In this operation, as shown in the embodiment, the arm is engaged with the engaging means and the engaged means, and one end side of the arm enters the standby holding portion bent from the first moving portion and is locked. The This switching to the locked state is performed by the biasing means for the arm in order to turn the other end side of the arm fitted to the second moving portion around the other end and shift the one end side to the standby holding portion side. It can be reliably locked only by setting the urging direction downward. Therefore, in this retracting mechanism, the urging force accumulation state can be stably maintained as compared with Patent Document 1, thereby eliminating the occurrence of malfunction.

請求項2の発明では、係合手段及び被係合部が互いに係脱する軸部か軸受部からなるため実施容易となる。これに対し、請求項3の発明では、付勢手段の付勢方向がアームの両端を結ぶ線よりも下方であるためアーム一端側を待受保持部により確実に移行さるようにする。   In the invention of claim 2, since the engaging means and the engaged portion are composed of a shaft portion or a bearing portion which engages with and disengages from each other, it is easy to implement. On the other hand, in the invention of claim 3, since the urging direction of the urging means is below the line connecting the both ends of the arm, one end side of the arm is surely shifted by the standby holding portion.

請求項4の発明では、第二移動部分がケースに対して摺動可能に設けられたスライダーであることから、アーム他端側を安定した状態で移動されるようにすると共に、形態例のごとく該スライダーを利用して回転式ダンパーやピストン式ダンパーを付設し易くなる。これに対し、請求項5の発明では、第二移動部分がケースに設けられた溝又は長孔であるため簡易化が図られる。また、請求項6の発明では、第二移動部分がケースに対し取付部を支点として回転可能なリンク部材であり、例えば請求項8のような展開が可能となる。   In the invention of claim 4, since the second moving part is a slider provided to be slidable with respect to the case, the other end side of the arm is moved in a stable state, and as in the embodiment. It becomes easy to attach a rotary damper or a piston damper using the slider. On the other hand, in the invention of claim 5, since the second moving part is a groove or a long hole provided in the case, simplification is achieved. In the invention of claim 6, the second moving part is a link member that can rotate with respect to the case with the mounting portion as a fulcrum. For example, the development as in claim 8 is possible.

請求項7の発明では、アームの移動速度が制動手段により制動されるため、可動体が付勢力により引き込まれるときに緩やかに移動されるようにし、それにより可動体の跳ね返りを防いだり高級感を付与できるようにする。これに対し、請求項8の発明では、ピストン式ダンパーを構成しているロッドのストロークを抑えて制動できる。   In the invention of claim 7, since the moving speed of the arm is braked by the braking means, the movable body is moved slowly when it is pulled by the urging force, thereby preventing the movable body from rebounding and giving a sense of quality. Be granted. On the other hand, in the invention of claim 8, braking can be performed while suppressing the stroke of the rod constituting the piston type damper.

In addition, a spring hooking portion 3 a is provided in a downward projecting manner in front of the other end portion 30.

以上のスライダー2及びアーム3並びにコイルばねSは、次のような手順にてケース1に組み込まれる。まず、スライダー2は、ケース1に対して一端面14と対向している他端面の開口からケース内に入れられると共に、両側の凸部24がガイド溝10b,11bに嵌合されることで該ガイド溝に沿って水平に摺動される。この場合、格納部11a内に装着されているダンパー側ピストンロッド36は、スライダー側挿入孔25に挿入され、かつ、小開口26に突出している先端にキャップ状止め具36aが装着されることでスライダー2に連結される。また、取付孔10cに装着されているダンパー37は、ギア39がスライダー側のラック27と噛み合わせられる。このため、スライダー2は、ピストン式ダンパー34及び回転式ダンパー37により制動されながら摺動されることになる。   The slider 2, the arm 3, and the coil spring S described above are assembled into the case 1 in the following procedure. First, the slider 2 is inserted into the case from the opening on the other end surface facing the one end surface 14 with respect to the case 1, and the convex portions 24 on both sides are fitted into the guide grooves 10b and 11b, thereby It is slid horizontally along the guide groove. In this case, the damper-side piston rod 36 mounted in the storage portion 11a is inserted into the slider-side insertion hole 25, and the cap-shaped stopper 36a is mounted on the tip protruding from the small opening 26. Connected to the slider 2. Further, the damper 37 mounted in the mounting hole 10c has the gear 39 engaged with the rack 27 on the slider side. For this reason, the slider 2 is slid while being braked by the piston damper 34 and the rotary damper 37.

また、アーム3は、図4のごとく他端部30の連結軸31aがスライダー側の支持部28に嵌合され、かつ、一端部32の軸部31bが案内溝15に挿通された状態でケース1内に組み込まれる。その際、一端部32は、径大の鍔部32aが第一移動部分15aの端部に少し大きく設けられた逃げ孔を利用して案内溝15に挿通されることで、ケース1に対し抜け止め状態に配置される。この状態では軸部33が案内溝15から水平に突出されている。次に、コイルばねSは、一端がケース側掛止部18に係止され、他端がアーム側掛止部3aにが係止される。これにより、引込本体Aが完成される。ここでのコイルばねSは、待受保持部15b側付近の掛止部18とアーム3の他端部30b側との間に配置され、かつ、付勢方向がアーム3の一端部32と他端部30とを結ぶ線よりも下方になるよう設定されている。   Further, as shown in FIG. 4, the arm 3 has a case in which the connecting shaft 31 a of the other end portion 30 is fitted to the support portion 28 on the slider side and the shaft portion 31 b of the one end portion 32 is inserted into the guide groove 15. 1 is incorporated. At this time, the one end portion 32 is removed from the case 1 by inserting the large flange portion 32a into the guide groove 15 using a clearance hole provided slightly larger at the end portion of the first moving portion 15a. Arranged in a stopped state. In this state, the shaft portion 33 projects horizontally from the guide groove 15. Next, one end of the coil spring S is locked to the case side latching portion 18 and the other end is latched to the arm side latching portion 3a. Thereby, the drawing-in main body A is completed. Here, the coil spring S is disposed between the latching portion 18 near the standby holding portion 15b side and the other end portion 30b side of the arm 3, and the urging direction is different from that of the one end portion 32 of the arm 3 and the like. It is set so as to be lower than the line connecting the end 30.

(被係合手段)この被係合手段Bは、図1及び図5に示されるように、板状の保持部材4と、保持部材4に所定上下寸法だけ移動可能に支持された軸受部材5とを備えている。このうち、保持部材4は、背面側に設けられた上下に長い矩形の凹部40と、凹部40内の上下部及び左右部を除いて表裏貫通した矩形の開口41と、凹部40内の上一側部分を欠如し凹部40内から外へ通じている逃げ部42と、複数箇所に設けられた取付孔43とを有している。 (Engaged means) As shown in FIGS. 1 and 5, the engaged means B includes a plate-like holding member 4 and a bearing member 5 supported by the holding member 4 so as to be movable by a predetermined vertical dimension. And. Of these, the holding member 4 includes a rectangular recess 40 that is long on the back side, a rectangular opening 41 that passes through the front and back except for the upper and lower portions and the left and right portions in the recess 40, and the upper one in the recess 40. It has a relief portion 42 that lacks a side portion and communicates from the inside of the recess 40 to the outside, and mounting holes 43 that are provided at a plurality of locations.

軸受部材5は、凹部40に対応した板部50と、板部50の表面側に突設されて開口41から正面側に突出配置される上軸受部51及び下軸受部52と、上軸受部51に上下動可能に組み込まれた爪部材45とを有している。板部50は、一方側面の上側に上記したガイド溝16に嵌合する突起53を形成しており、凹部40内に上下方向へ移動可能に配置されたとき、突起53も逃げ部42から外へ突出した状態で上下動される。上軸受部51及び下軸受部52は、開口41から板部50の正面側へ上下動可能に突出された状態で、上軸受部51の両外側面に設けられた爪55を介して抜け止めされる。下軸受部52は、下に行くほど低くなるテーパーに形成されて、上記係止状態の軸部33に当たったとき、被係合手段Bの前進移動によって軸部33を前記テーパー作用により待受保持部15bより第一移動部分15aに逃がす。   The bearing member 5 includes a plate portion 50 corresponding to the concave portion 40, an upper bearing portion 51 and a lower bearing portion 52 that are provided on the front surface side of the plate portion 50 so as to protrude from the opening 41 to the front side, and an upper bearing portion. 51, and a claw member 45 incorporated so as to be movable up and down. The plate portion 50 has a projection 53 that fits into the above-described guide groove 16 on the upper side of one side surface. When the plate portion 50 is disposed in the recess 40 so as to be movable in the vertical direction, the projection 53 is also removed from the escape portion 42. It is moved up and down while protruding to the side. The upper bearing portion 51 and the lower bearing portion 52 are prevented from coming off via claws 55 provided on both outer side surfaces of the upper bearing portion 51 in a state where the upper bearing portion 51 and the lower bearing portion 52 protrude from the opening 41 to the front side of the plate portion 50 so as to be vertically movable. Is done. The lower bearing portion 52 is formed in a taper that becomes lower as it goes downward. When the lower bearing portion 52 comes into contact with the shaft portion 33 in the locked state, the shaft portion 33 is awaited by the taper action by the forward movement of the engaged means B. It escapes from the holding portion 15b to the first moving portion 15a.

これに対し、上軸受部51は、突出先端側が下部及び端面の一部54を開口した空洞部となっている。そして、該空洞部には、両内側面に爪部材45を案内するガイドリブ56が対向して設けられている。すなわち、爪部材45は、図5(b),(d)のごとく、先端が傾斜面に形成されると共に、両側に設けられた縦溝45aと、上側に突設された弾性片部46を有している。そして、爪部材45は、各縦溝45aを対応するガイドリブ56に嵌合し、かつ、片部46を前記空洞部の内上面に当接した状態に配置されることにより、通常は片部46を介して同図の突出状態に付勢されている。上向きの応力を受けると、片部46の弾性力に抗して没方向へ一旦逃げた後、応力がなくなると再び突出状態となる。   On the other hand, the upper bearing portion 51 is a hollow portion in which the projecting tip side opens the lower portion and a part 54 of the end surface. And the guide part 56 which guides the nail | claw member 45 is provided in this hollow part facing both inner side surfaces. That is, as shown in FIGS. 5B and 5D, the claw member 45 has a tip formed on an inclined surface, and has a vertical groove 45a provided on both sides and an elastic piece 46 projecting upward. Have. The claw member 45 is normally fitted to the corresponding guide rib 56 in each longitudinal groove 45a and disposed in a state in which the piece 46 is in contact with the inner upper surface of the hollow portion. Is biased to the protruding state of FIG. When the stress is applied upward, it once escapes in the sinking direction against the elastic force of the piece 46, and then returns to the protruding state when the stress disappears.

(使用例)図6(及び図1中、右上に示された部分)は以上の引込機構を引出体8の引き込みに適用した一例である。この配置では、引込本体Aが収納本体9の内側面に取り付けられると共に、被係合手段Bが引出体8の後端面8bに取り付けられている。この場合、引込本体Aは取付部19及びねじ等を使用して固着される。被係合手段Bは、取付孔43及びねじ等を使用して固着されるが、その際、突起53が引込本体Aのガイド溝16に対応して、引出体側面8aから突出するよう位置決めされる。なお、他の配置としては、引込本体Aを引出体8側に取り付け、それに対応して被係合手段Bを収納本体9側に取り付けることも可能である。また、引込本体A及び被係合手段Bは、可動体を2組使用して引き込むこともあるが、そのような場合、引出体8であればもう一方は上記形態に対し左右対称形となる。 (Usage example) FIG. 6 (and the portion shown in the upper right in FIG. 1) is an example in which the above-described retracting mechanism is applied to retracting the drawer body 8. In this arrangement, the retractable main body A is attached to the inner side surface of the storage main body 9 and the engaged means B is attached to the rear end surface 8 b of the drawer body 8. In this case, the lead-in main body A is fixed using the mounting portion 19 and screws. The engaged means B is fixed by using the mounting hole 43 and screws or the like. At this time, the protrusion 53 is positioned so as to protrude from the drawer body side surface 8a corresponding to the guide groove 16 of the drawing body A. The As another arrangement, it is also possible to attach the retracting main body A to the drawer body 8 side and correspondingly attach the engaged means B to the storage body 9 side. In addition, the retractable body A and the engaged means B may be retracted by using two sets of movable bodies. In such a case, if the drawer body 8 is used, the other is symmetrical with respect to the above-described form. .

(作動)以上の引込機構の作動を図3と図4、及び図7〜図9を参照しながら詳述する。なお、図7〜図9では、図6の使用例を想定して主な作動を示したものであり、各部材の関係を明らかにするため簡略化したり模式化されている。 (Operation) The operation of the above retracting mechanism will be described in detail with reference to FIGS. 3 and 4 and FIGS. 7 to 9 show main operations assuming the use example of FIG. 6, and are simplified or modeled in order to clarify the relationship between the members.

(1)まず、引込本体Aの作動特徴は、コイルばねSが図3のごとく付勢力を蓄積した付勢力蓄積状態と、コイルばねSが図4のごとく付勢力を解放した付勢力解放状態ないしは引込状態とに切り換えられる。付勢力蓄積状態において、コイルばねSはアーム3の摺動を介して付勢力を最大まで蓄積している。アーム3は軸部31bを待受保持部15bに係止している。ダンパー34はピストンロッド36がシリンダー35から大きく引き出されている。そして、付勢力蓄積状態から、軸部31bが待受保持部15bから係止解除されて第一移動部分15aに逃がされると、軸部33、アーム3、スライダー2がコイルばねSの付勢力で一体として第一移動部分15aに沿って摺動される。この係止解除は、後述する軸部33に対する被係合手段Bの係合を伴って行われる。係止解除されると、被係合手段Bは、軸部33と軸受部材5との係合状態を保ってアーム3と連動して摺動、つまり上記ダンパー34,37で制動されながら自動的に引き込まれる。この引込機構では、付勢力解放状態ないしは引込完了状態において、コイルばねSはアーム3の摺動を介して付勢力を解放ないしは付勢力を最小にしている。アーム3は軸部31bを第一移動部分15aの適宜な箇所に配置している。ダンパー34はピストンロッド36をシリンダー35に最も没した状態となっている。 (1) First, the operation feature of the retractable body A is that the coil spring S accumulates the urging force as shown in FIG. 3 and the urging force released state where the coil spring S releases the urging force as shown in FIG. Switch to the retracted state. In the urging force accumulation state, the coil spring S accumulates the urging force to the maximum through sliding of the arm 3. The arm 3 locks the shaft portion 31b to the standby holding portion 15b. In the damper 34, the piston rod 36 is largely pulled out from the cylinder 35. When the shaft portion 31b is released from the standby holding portion 15b and released to the first moving portion 15a from the biasing force accumulation state, the shaft portion 33, the arm 3, and the slider 2 are moved by the biasing force of the coil spring S. It is slid along the first moving portion 15a as a unit. This unlocking is performed with the engagement of the engaged means B with the shaft portion 33 described later. When unlocked, the engaged means B slides in conjunction with the arm 3 while maintaining the engaged state of the shaft portion 33 and the bearing member 5, that is, automatically while being braked by the dampers 34 and 37. Be drawn into. In this retracting mechanism, the coil spring S releases the urging force or minimizes the urging force through sliding of the arm 3 in the urging force released state or in the retracted state. The arm 3 has the shaft portion 31b disposed at an appropriate position of the first moving portion 15a. The damper 34 has the piston rod 36 most immersed in the cylinder 35.

(2)図7は、被係合手段Bが引込本体Aに係合する前段階で、互いの係合位置関係をガイド手段7により矯正する作動を示している。これは、図6の使用例だと、例えば、引出体8の積載量や収納荷重の変化により、軸受部材5を構成している上軸受部51に配置された爪部材45及び下軸受部52と、引込本体Aの軸部33との相対位置が変化し、爪部材45及び下軸受部52と軸部33とが正常に係合されなくという問題をガイド手段7により解消する。すなわち、このガイド手段7は、図7(b)のごとく被係合手段Bが引込本体Aに接近されると、(ア)軸受部側突起53がケース側ガイド溝16に対し嵌合した状態で摺動されるため軸受部材5(下軸受部52及び爪部材45)と軸部33とが正確に位置出しされること、(イ)突起53がガイド溝16のうち幅広の溝出入口部分16aで受け入れられて幅細の溝部分16bにセンタリングされながら移行されるため軸受部材5(下軸受部52及び爪部材45)と軸部33との溝幅方向つまり上下位置が変化していても効率よく修正されること、(ウ)軸受部材5(下軸受部52及び爪部材45)が保持部材4に対し所定寸法だけ移動可能に支持されていることから該許容された移動範囲内で位置を変更して軸部33に対して最適位置に調整されること、それらの作動により前記相対位置の変化を効率よく確実に吸収し誤作動をなくする。 (2) FIG. 7 shows the operation of correcting the engagement position relationship with the guide means 7 before the engaged means B is engaged with the retractable body A. In the usage example of FIG. 6, for example, the claw member 45 and the lower bearing portion 52 arranged in the upper bearing portion 51 constituting the bearing member 5 due to a change in the loading amount and the storage load of the drawer body 8. The guide means 7 solves the problem that the relative position of the retractable body A with the shaft portion 33 changes and the claw member 45 and the lower bearing portion 52 and the shaft portion 33 are not normally engaged. That is, when the engaged means B approaches the retracting body A as shown in FIG. 7B, the guide means 7 is in a state in which (a) the bearing portion side protrusion 53 is fitted into the case side guide groove 16. Therefore, the bearing member 5 (the lower bearing portion 52 and the claw member 45) and the shaft portion 33 are accurately positioned, and (a) the protrusion 53 has a wide groove inlet / outlet portion 16a in the guide groove 16. And is moved while being centered in the narrow groove portion 16b. Therefore, even if the groove width direction of the bearing member 5 (the lower bearing portion 52 and the claw member 45) and the shaft portion 33, that is, the vertical position is changed, the efficiency is improved. (C) Since the bearing member 5 (the lower bearing portion 52 and the claw member 45) is supported so as to be movable by a predetermined dimension with respect to the holding member 4, the position thereof is within the allowable movement range. Change to adjust to the optimal position for shaft 33 It is the fact, to efficiently and reliably absorb a change in the relative position by their malfunction eliminating operation.

(3)図8は、被係合手段Bが引込本体Aに係合して付勢力により引き込まれるときの引込作動を示している。すなわち、この引込機構では、被係合手段Bが図8(a)のごとく引込本体Aに接近されると、まず、軸受部材側爪部材45が上記した片部46の付勢に抗して上へ動いて軸部33を通過し、同時に軸部33が下軸受部52のテーパー形状により上又は斜め上方向へ押されることで待受保持部15bから第一移動部分15aに逃がされて係止解除される。この係止解除は、アーム3が他端部側軸部31aを支点に回動して一端部32を上方向へ変位する。これにより、被係合手段Bは、図8(b)のごとく軸受部材5(下軸受部52及び爪部材45)と軸部33との係合を保って、アーム3及びスライダー2がコイルばねSの付勢力により摺動され、引出体等の可動体がその摺動に連動して引き込まれる。これは、上記図6の使用例だと、引出体8が押し入れられる途中からコイルばねSに蓄積された付勢力により自動的に最終の押入位置まで(制動手段6により制動されながら)引き込まれるようにし、それにより引出体8を勢いよく押し込めるときの跳ね返りを防いだり引出体8の不完全な押入状態の発生を防ぐ。 (3) FIG. 8 shows the retraction operation when the engaged means B is engaged with the retraction main body A and is retracted by the urging force. That is, in this retracting mechanism, when the engaged means B is approached to the retracting main body A as shown in FIG. 8A, first, the bearing member side claw member 45 resists the biasing of the above-described piece 46. The shaft portion 33 moves upward and passes through the shaft portion 33. At the same time, the shaft portion 33 is pushed upward or obliquely upward by the tapered shape of the lower bearing portion 52, so that it is released from the standby holding portion 15b to the first moving portion 15a. The lock is released. In this unlocking, the arm 3 rotates about the other end side shaft portion 31a as a fulcrum, and the one end portion 32 is displaced upward. Thus, the engaged means B maintains the engagement between the bearing member 5 (the lower bearing portion 52 and the claw member 45) and the shaft portion 33 as shown in FIG. 8B, and the arm 3 and the slider 2 are coil springs. It is slid by the urging force of S, and a movable body such as a drawer is drawn in conjunction with the sliding. In the use example of FIG. 6 described above, the drawing body 8 is automatically pulled to the final pushing position (while being braked by the braking means 6) by the urging force accumulated in the coil spring S from the middle of being pushed in. Thus, the rebound when the drawer body 8 is pushed in vigorously is prevented, and the occurrence of an incomplete push-in state of the drawer body 8 is prevented.

(4)図9は、引出体8等の可動体が図8(b)の引き込まれた状態から再び引き出し方向へ移動されて前記係合を解除するときの作動を示している。すなわち、この引込機構では、被係合手段Bが再び図9(a)のごとく引込本体Aから離れる方向へ移動される過程において、まず、軸部33が軸受部材5(下軸受部52及び爪部材45)と係合した状態で、第一移動部分15aから一段低くなった待受保持部15b上にくると、爪部材45で押されて待受保持部15bに入って係止される。この係止状態への切り換えは、アーム3が他端部側軸部31aを支点に回動して一端部側軸部31bを待受保持部15b側である下方向へ変位すること、コイルばねSの付勢方向がアーム3の両端部を結ぶ線よりも待受保持部15bと同じ下方向であること、アーム3がその付勢力の一部で軸部31bを待受保持部15b側へ変位するよう押圧されていること、等により軸部31bが待受保持部15bに確実に係止される。その結果、この引込機構では、特許文献1と比較して付勢力蓄積状態を常に安定保持でき、それにより誤作動の発生を解消できる。加えて、待受保持部15bの溝深さを浅くすることも可能となり、それにより高さ方向のスペースを抑えてコンパクト化も図り易くなる。なお、この引出機構では、軸部33が下軸受部52及び爪部材45と係合した状態で、被係合手段Bが引出体8等の引き出し操作により図8(b)から図9(a)の箇所まで移動されると、軸部33つまりアーム3及びスライダー2も連動して同方向へ移動されるためコイルばねSに付勢力を蓄積することになる。勿論、この付勢力蓄積は、被係合手段Bの軸受部材5(下軸受部52及び爪部材45)が軸部33と係合解除されるまでである。すなわち、軸部31bが待受保持部15aに係止した後、被係合手段Bは図9(b)のごとく軸受部を構成している下軸受部52及び爪部材45が軸部33との係合を解除し、単独で操作方向へ移動されることになる。 (4) FIG. 9 shows the operation when a movable body such as the drawer 8 is moved again from the retracted state in FIG. 8B in the drawing direction to release the engagement. That is, in this retracting mechanism, in the process in which the engaged means B is moved again away from the retracting body A as shown in FIG. 9A, first, the shaft portion 33 is moved to the bearing member 5 (the lower bearing portion 52 and the pawl). In a state where it is engaged with the member 45), when it comes to the standby holding portion 15b that is one step lower than the first moving portion 15a, it is pushed by the claw member 45 and enters the standby holding portion 15b to be locked. The switching to the locked state is performed by the arm 3 rotating about the other end side shaft portion 31a as a fulcrum and displacing the one end portion side shaft portion 31b downward on the standby holding portion 15b side, a coil spring. The biasing direction of S is the same downward direction as the standby holding portion 15b with respect to the line connecting both ends of the arm 3, and the arm 3 moves the shaft portion 31b toward the standby holding portion 15b with a part of the biasing force. The shaft portion 31b is reliably locked to the standby holding portion 15b by being pressed so as to be displaced. As a result, in this retracting mechanism, the urging force accumulation state can always be stably maintained as compared with Patent Document 1, thereby eliminating the occurrence of malfunction. In addition, it is possible to reduce the groove depth of the standby holding portion 15b, which facilitates downsizing by reducing the space in the height direction. In this drawer mechanism, with the shaft portion 33 engaged with the lower bearing portion 52 and the claw member 45, the engaged means B is operated by pulling out the drawer body 8 and the like, as shown in FIGS. ), The shaft portion 33, that is, the arm 3 and the slider 2 are also moved in the same direction in conjunction with each other, so that the urging force is accumulated in the coil spring S. Of course, this urging force accumulation is until the bearing member 5 (the lower bearing portion 52 and the claw member 45) of the engaged means B is disengaged from the shaft portion 33. That is, after the shaft portion 31b is locked to the standby holding portion 15a, the engaged means B includes the lower bearing portion 52 and the claw member 45 constituting the bearing portion as shown in FIG. Is disengaged and moved alone in the operation direction.

(第1変形例)図10及び図11の第1変形例は上記形態を簡略化した一例である。この説明では、上記形態と同一部材及び作用的に同じ部位に同じ符号を付し、変更した構成だけ述べて重複した記載を極力省く。 (First Modification) The first modification shown in FIGS. 10 and 11 is an example in which the above embodiment is simplified. In this description, the same members as those in the above embodiment and the same functional parts are denoted by the same reference numerals, and only the changed configuration is described to avoid redundant descriptions as much as possible.

この引出機構では、上記引込本体Aの構成部材のうち、スライダー2及び回転式ダンパー6が省略されている。すなわち、この引込本体Aは、ケース1と、軸部33を有したアーム3と、付勢手段としてのコイルばねSと、アーム3の移動を制動するピストン式ダンパー34とを備えている。   In this drawing mechanism, the slider 2 and the rotary damper 6 are omitted from the constituent members of the pull-in main body A. That is, the retractable body A includes a case 1, an arm 3 having a shaft portion 33, a coil spring S as urging means, and a piston type damper 34 that brakes the movement of the arm 3.

ケース1は、前後方向に細長くなっており、内空間が正面10及び背面11と、上下面12,13と、一端面14とで概略区画されており、他端面を開口している。正面10及び背面11には、第二移動部分としての溝又は長孔10e,11eが対向して設けられている。各長孔10e,11eは、案内溝15の第一移動部分15aとほぼ同じ長さの直線状で、アーム3の移動方向に延びている。アーム3の他端部30は、略コ形をなし、該コ形の両片部間に設けられた上記した連結軸31aと共に、コ形の両片部外面に突設された軸部31cを有している。そして、アーム他端部30は、両側の軸部31cが対応する長孔10e,11eに嵌合されており、該嵌合状態でアーム3の回動及び移動を許容するようになっている。   The case 1 is elongated in the front-rear direction, and the inner space is roughly partitioned by the front face 10 and the rear face 11, the upper and lower faces 12, 13, and one end face 14, and the other end face is opened. Grooves or long holes 10e, 11e as second moving parts are provided on the front surface 10 and the back surface 11 so as to face each other. Each of the long holes 10 e and 11 e is a straight line having substantially the same length as the first moving portion 15 a of the guide groove 15 and extends in the moving direction of the arm 3. The other end 30 of the arm 3 is substantially U-shaped, and together with the above-described connecting shaft 31a provided between the U-shaped pieces, a shaft 31c protruding from the outer surfaces of the U-shaped pieces is provided. Have. The arm other end 30 is fitted in the corresponding long holes 10e and 11e with the shaft portions 31c on both sides, and the arm 3 is allowed to rotate and move in the fitted state.

また、ケース1には、ピストン式ダンパー34のシリンダー35が長孔10e,11eとケース他端面との間に装着可能となっている。そして、ダンパー34は、シリンダー35がケース1に対して後端をケース外へ突出した状態に装着されると共に、ピストンロッド36が前記した連結軸31aに設けられた不図示の貫通孔に挿入され、かつ、該貫通孔から突出した先端にキャップ状止め具36bが装着されることでアーム他端部30に連結されている。以上の引込機構でも上記形態と同様に作動すると共に、スライダー2が省略される分だけ簡略化されることになる。   Moreover, the cylinder 1 of the piston type damper 34 can be attached to the case 1 between the long holes 10e and 11e and the other end surface of the case. The damper 34 is mounted in a state where the cylinder 35 protrudes out of the case with respect to the case 1 and the piston rod 36 is inserted into a through hole (not shown) provided in the connecting shaft 31a. In addition, the cap-like stopper 36b is attached to the tip protruding from the through hole, and is connected to the arm other end 30. The above retracting mechanism operates in the same manner as in the above embodiment, and is simplified to the extent that the slider 2 is omitted.

(第2変形例)図12〜図14の第2変形例は上記係合手段を軸部から軸受部構成に変更し、逆に被係合手段Bを軸受部から軸部構成に変更した一例である。また、この変形例では上記したガイド手段7が省略されている。この説明では、上記形態及び第1変形例と同一部材及び作用的に同じ部位に同じ符号を付し、変更した構成についてだけ詳述する。 (Second Modification) The second modification shown in FIGS. 12 to 14 is an example in which the engaging means is changed from the shaft portion to the bearing portion configuration, and conversely, the engaged means B is changed from the bearing portion to the shaft portion configuration. It is. Further, in this modified example, the guide means 7 described above is omitted. In this description, the same members and operatively the same parts as those in the above embodiment and the first modified example are denoted by the same reference numerals, and only the changed configuration will be described in detail.

この引出機構では、上記したアーム一端側の軸部33に代えて軸受部133とし、被係合部Bがその軸受部133に係脱される軸部140を有する構成としたものである。すなわち、軸受部133は、上記したアーム一端部側の軸部31b或いは鍔部32に連結した状態に設けられ、軸部140を係脱可能な略コ形状となっている。軸受部133の形状は、コ形状上片部134a内面が先端に行くほど高くなるテーパーに形成されると共に、コ形状下片部の先端に設けられた上向きの抜止用突起134bを有している。   In this drawing mechanism, the bearing portion 133 is used instead of the shaft portion 33 on the one end side of the arm, and the engaged portion B includes a shaft portion 140 that is engaged with and disengaged from the bearing portion 133. That is, the bearing portion 133 is provided in a state of being connected to the shaft portion 31b or the flange portion 32 on the arm one end portion side, and has a substantially U shape capable of engaging and disengaging the shaft portion 140. The shape of the bearing portion 133 is formed in a taper that becomes higher as the inner surface of the U-shaped upper piece portion 134a goes to the tip, and has an upward retaining protrusion 134b provided at the tip of the U-shaped lower piece portion. .

これに対し、被係合部Bは、軸部140、保持部材142及びベース143などを有している。軸部140は、保持部材142に対し付勢ばね141の付勢力に抗して突出寸法を変位可能に支持されていると共に、ベース143に対し保持部材142を所定寸法だけ移動可能に支持されている。ここで、軸部140は鋼材であり、支持部150に突設されている。支持部150は、両側面に設けられた係止爪150aと、軸部140を突出している側と反対側を凹状に形成した穴部150bとを有している。保持部材142は概略T形であり、支持部150を摺動自在に配置する保持穴を形成していると共に、両側面にそれぞれ設けられているガイド孔142a及び凸部142bを有している。両側のガイド孔142aは、前後方向に延び、支持部150が穴部150bに付勢ばね141を配置した状態で保持部材142の保持穴に挿入されたとき、係止爪150aと嵌合することで支持部150を摺動自在に抜け止めする。凸部142bは、前側でガイド孔142aを挟んだ上下に設けられている。 On the other hand, the engaged portion B includes a shaft portion 140, a holding member 142, a base 143, and the like. The shaft portion 140 is supported so that the protruding dimension can be displaced against the urging force of the urging spring 141 with respect to the holding member 142, and the holding member 142 is supported to be movable with respect to the base 143 by a predetermined dimension. Yes. Here, the shaft portion 140 is a steel material, and is protruded from the support portion 150. The support part 150 has the latching claw 150a provided in both sides | surfaces, and the hole 150b which formed the recessed part in the opposite side to the side which protrudes the axial part 140. As shown in FIG. The holding member 142 is substantially T-shaped, has a holding hole in which the support portion 150 is slidably disposed, and has a guide hole 142a and a convex portion 142b provided on both side surfaces, respectively. The guide holes 142a on both sides extend in the front-rear direction, and when the support part 150 is inserted into the holding hole of the holding member 142 in a state where the urging spring 141 is disposed in the hole part 150b, the guide hole 142a is fitted with the locking claw 150a. Thus, the support portion 150 is slidably retained. The convex portions 142b are provided above and below the guide hole 142a on the front side.

ベース143は、板部144及び板部144の片側に設けられた張出部146を一体に有している。板部144と張出部146の間は、保持空間147が区画形成され、保持空間147の奥側が側壁148で閉じられている。板部144及び張出部146には、上下に延びる規制溝144a及び146bが対向して設けられると共に、左右に延びる対の凹部145及び凹部146aが対向して設けられている。凹部145及び凹部146aは、規制溝144a及び146bに通じており、各凸部142bを嵌合した状態で規制溝144a及び146bまで誘導可能にする。側壁148には長孔149が設けられている。以上のベース143には、保持部材142が軸部140を組み付けた状態で、各凸部142bを凹部145及び凹部146aに嵌合して保持空間147内へ移動されると、軸部140が長孔149から外へ突出され、かつ各凸部142bが凹部145及び凹部146aから規制溝144a及び146bに嵌合される。これにより、保持部材142は、軸部140をその突出寸法を付勢力に抗して可変可能に支持し、また、ベース143に対して各凸部142bを規制溝144a及び146bに摺動可能に嵌合した状態に支持されて、軸部140が長孔149に対し孔寸法に応じた距離だけ上下に移動可能となる。符号144bと144cはベース143に付設された取付孔である。   The base 143 integrally includes a plate portion 144 and an overhang portion 146 provided on one side of the plate portion 144. A holding space 147 is defined between the plate portion 144 and the overhanging portion 146, and the back side of the holding space 147 is closed by a side wall 148. The plate portion 144 and the overhang portion 146 are provided with restriction grooves 144a and 146b extending vertically, and provided with a pair of recesses 145 and recesses 146a extending left and right. The recesses 145 and 146a communicate with the regulation grooves 144a and 146b, and can be guided to the regulation grooves 144a and 146b in a state where the projections 142b are fitted. A long hole 149 is provided in the side wall 148. In the state where the holding member 142 is assembled with the shaft portion 140 in the above-described base 143, when the protrusions 142 b are fitted into the recesses 145 and 146 a and moved into the holding space 147, the shaft portion 140 is long. The protrusions 142b protrude outward from the holes 149, and the protrusions 142b are fitted into the restriction grooves 144a and 146b from the recesses 145 and 146a. As a result, the holding member 142 supports the shaft portion 140 such that the projecting dimension thereof can be varied against the urging force, and the convex portions 142b can slide in the restriction grooves 144a and 146b with respect to the base 143. Supported by the fitted state, the shaft portion 140 can move up and down by a distance corresponding to the hole size with respect to the elongated hole 149. Reference numerals 144 b and 144 c are attachment holes attached to the base 143.

以上の引込機構において、図12(a)は図8(a)に対応し、図12(b)は図8(b)に対応している。すなわち、図12(a)は、被係合手段Bの軸部140が引込本体Aの軸受部133に係合する直前の状態を示している。この引込機構では、被係合手段Bの軸部140が軸受部133に接近されると、軸部140が軸受部側上片部134aの内側テーパー面に当たる。すると、軸部140は、上片部134aのテーパー面から上向きの応力を受けて、保持部材42を介して長孔149に対し所定寸法だけ上方へ移行し、それにより図12(b)のように軸受部133のコ形内に係合する。同時に、上記したアーム一端側の軸部33(不図示)が待受保持部15bから第一移動部分15aに逃がされて係止解除される。これにより、被係合手段Bは、図12(b)のごとく軸受部133と軸部140との係合を保って、アーム3がコイルばねSの付勢力により摺動され、引出体等の可動体がその摺動に連動して引き込まれる。また、引出体等の可動体が図12(b)の引き込まれた状態から再び引き出し方向へ移動される過程において、軸部140は軸受部133と係合した状態で、第一移動部分15aから一段低くなった待受保持部15b上にくると、保持部材42を介して長孔149に対し所定寸法だけ下方へ移行されて係合解除されることになる。   In the above retracting mechanism, FIG. 12A corresponds to FIG. 8A, and FIG. 12B corresponds to FIG. That is, FIG. 12A shows a state immediately before the shaft portion 140 of the engaged means B is engaged with the bearing portion 133 of the pull-in main body A. In this retracting mechanism, when the shaft portion 140 of the engaged means B approaches the bearing portion 133, the shaft portion 140 hits the inner tapered surface of the bearing portion-side upper piece portion 134a. Then, the shaft portion 140 receives upward stress from the taper surface of the upper piece portion 134a, and moves upward by a predetermined dimension with respect to the long hole 149 via the holding member 42, thereby, as shown in FIG. To the inside of the U-shape of the bearing portion 133. At the same time, the shaft portion 33 (not shown) on the one end side of the arm is released from the standby holding portion 15b to the first moving portion 15a and unlocked. As a result, the engaged means B maintains the engagement between the bearing portion 133 and the shaft portion 140 as shown in FIG. 12B, and the arm 3 is slid by the urging force of the coil spring S. The movable body is pulled in conjunction with the sliding. Further, in the process in which the movable body such as the drawer body is moved again from the retracted state in FIG. 12B in the pulling direction, the shaft portion 140 is engaged with the bearing portion 133 from the first moving portion 15a. When it comes on the standby holding portion 15b that is lowered by one step, it is moved downward by a predetermined dimension with respect to the long hole 149 via the holding member 42 and is disengaged.

(第3変形例)図15の第3変形例は第二移動部分の構成及びピストン式ダンパーとの関係を変更した例である。この説明では、上記形態及び第1変形例や第2変形例と同一部材及び作用的に同じ部位に同じ符号を付し、変更した構成についてだけ詳述する。 (Third Modification) The third modification of FIG. 15 is an example in which the configuration of the second moving part and the relationship with the piston type damper are changed. In this description, the same reference numerals are given to the same members and operatively the same parts as those of the above-described embodiment and the first and second modified examples, and only the changed configuration will be described in detail.

この引出機構では、上記引込本体Aに対し、第二移動部分がケース1内に回転可能に取り付けられたリンク部材80にて構成されている点と、制動手段であるピストン式ダンパー34が連接部材90及びリング部材80を介してアーム3を制動するよう構成されている点で変更されている。   In this drawing mechanism, a point where the second moving part is constituted by a link member 80 rotatably attached to the case 1 with respect to the drawing main body A, and a piston type damper 34 which is a braking means is a connecting member. 90 and the ring member 80 is modified in that the arm 3 is braked.

すなわち、ケース1は、内空間が正面10及び背面11と、上下面12,13と、両端面とで概略区画されている。正面10及び背面11にはガイド部10f,11fが対向して設けられている。ガイド部10f,11fは、案内溝15(第一移動部分15a及び待受保持部15b)から離れる側に設けられて、第一移動部分15aと同じ直線溝でアーム3の移動方向に延びている。ケース1内には、ピストン式ダンパー34のシリンダー35が下側でかつ左右略中間部に装着されていると共に、リンク部材80及び連接部材90がダンパー34のピストンロッド36に対応して設けられている。このうち、リンク部材80は、全体が細長い板状をなし、中間部分に設けられた肉薄部及び該薄肉部に設けられたピン用孔と、下端部に設けられた軸孔とを有し、下端部が前記軸孔に挿通される枢軸Mを介して回転可能に取り付けられた状態で、上端部が上記アーム他端部30に対し連結軸31a等を介して嵌合連結される。これに対し、連接部材90は、側面から見ると、略T形に形成されており、水平片部91及び垂直片部92とからなる。水平片部91は、両側面に設けられた突起91aと、先端に設けられた略コ形の嵌合部と、該嵌合部に設けられた縦孔91bとを有している。そして、以上の連接部材90は、例えば、両側の突起91aを前記ガイド部10f,11fに摺動可能に嵌合すると共に、前記した先端嵌合部のコ形内にリンク部材80の中間薄肉部を嵌合するようケース1内に組み込まれる。その後、リンク部材80及び連接部材90は、ピンPが一方縦孔91b、リンク部材80の薄肉部側のピン用孔、他方縦孔91bに配設されることにより作動連結される。   That is, the inner space of the case 1 is roughly divided by the front surface 10 and the back surface 11, the upper and lower surfaces 12, 13, and both end surfaces. Guide portions 10f and 11f are provided on the front surface 10 and the back surface 11 so as to face each other. The guide portions 10f and 11f are provided on the side away from the guide groove 15 (the first moving portion 15a and the standby holding portion 15b), and extend in the moving direction of the arm 3 in the same linear groove as the first moving portion 15a. . In the case 1, the cylinder 35 of the piston type damper 34 is mounted on the lower side and substantially in the middle of the left and right, and the link member 80 and the connecting member 90 are provided corresponding to the piston rod 36 of the damper 34. Yes. Among these, the link member 80 is formed in an elongated plate shape as a whole, and has a thin portion provided in the intermediate portion, a pin hole provided in the thin portion, and a shaft hole provided in the lower end portion, With the lower end portion rotatably attached via a pivot M inserted through the shaft hole, the upper end portion is fitted and connected to the arm other end portion 30 via a connecting shaft 31a or the like. On the other hand, the connecting member 90 is formed in a substantially T shape when viewed from the side, and includes a horizontal piece portion 91 and a vertical piece portion 92. The horizontal piece portion 91 has protrusions 91a provided on both side surfaces, a substantially U-shaped fitting portion provided at the tip, and a vertical hole 91b provided in the fitting portion. The connecting member 90 described above includes, for example, the protrusions 91a on both sides slidably fitted to the guide portions 10f and 11f, and the intermediate thin portion of the link member 80 in the U-shape of the tip fitting portion described above. Are assembled in the case 1 so as to be fitted. Thereafter, the link member 80 and the connecting member 90 are operatively connected by arranging the pin P in the one vertical hole 91b, the pin hole on the thin portion side of the link member 80, and the other vertical hole 91b.

以上の引込機構において、図15(a)は、図3(c)に対応し、図15(b)は図4(b)に対応している。すなわち、作動特徴としては、図15(a)に示されるコイルばねSが付勢力を蓄積した付勢力蓄積状態と、コイルばねSが図15(b)のごとく付勢力を解放した付勢力解放状態ないしは引込状態とに切り換えられる。付勢力蓄積状態において、コイルばねSはアーム3の摺動を介して付勢力を最大まで蓄積している。アーム3は軸部31bを待受保持部15bに係止している。ダンパー34はピストンロッド36がシリンダー35から引き出されて連接部材90の垂直片部92に当接もしくは接続されている。そして、付勢力蓄積状態から、軸部31bが待受保持部15bから係止解除されて第一移動部分15aに逃がされると、アーム3がコイルばねSの付勢力で第一移動部分15aに沿って摺動される。このアーム3の摺動は、アーム他端部30がリンク部材80の回転作動を伴って許容される。すなわち、この引込機構では、軸部31bが待受保持部15bから係止解除されると、リンク部材80が枢軸Mを支点とした時計回りないしは案内溝15側への回転される。すると、連接部材90は、リンク部材80の回転によって押圧されながら突起91aとガイド部10f,11fとのガイド作用を伴って、かつダンパー34で制動されながら図15(a)から同(b)の位置まで摺動される。図15(b)の付勢力解放状態ないしは引込完了状態において、ダンパー34はピストンロッド36をシリンダー35に最も没した状態となっている。以上のように、アーム3の摺動をダンパー34で制動する構成として、リンク部材80及び連接部材90を介してダンパー34に作動連結すると、例えば、ピストンロッド3のストロークを半分程度に抑えることができ制動効率を向上できる。   In the above retracting mechanism, FIG. 15A corresponds to FIG. 3C, and FIG. 15B corresponds to FIG. That is, as an operation feature, the urging force accumulation state where the coil spring S shown in FIG. 15A accumulates the urging force and the urging force released state where the coil spring S releases the urging force as shown in FIG. 15B. Or switched to the retracted state. In the urging force accumulation state, the coil spring S accumulates the urging force to the maximum through sliding of the arm 3. The arm 3 locks the shaft portion 31b to the standby holding portion 15b. In the damper 34, the piston rod 36 is pulled out from the cylinder 35 and is in contact with or connected to the vertical piece 92 of the connecting member 90. Then, when the shaft portion 31b is released from the standby holding portion 15b and released to the first moving portion 15a from the biasing force accumulation state, the arm 3 moves along the first moving portion 15a with the biasing force of the coil spring S. Are slid. The sliding of the arm 3 is allowed with the rotation of the link member 80 at the other end 30 of the arm. That is, in this retracting mechanism, when the shaft portion 31b is unlocked from the standby holding portion 15b, the link member 80 is rotated clockwise or pivoted toward the guide groove 15 with the pivot M as a fulcrum. Then, the connecting member 90 is guided by the protrusion 91a and the guide portions 10f and 11f while being pressed by the rotation of the link member 80, and is braked by the damper 34 as shown in FIG. Slide to position. In the urging force released state or the retracted state shown in FIG. 15B, the damper 34 is in a state where the piston rod 36 is most submerged in the cylinder 35. As described above, when the sliding movement of the arm 3 is braked by the damper 34, when the operative connection is made to the damper 34 via the link member 80 and the connecting member 90, for example, the stroke of the piston rod 3 can be suppressed to about half. And braking efficiency can be improved.

なお、本発明の引込機構は、請求項で特定される構成を実質的に備えておればよく、細部はこの形態及び各変形例を参考にして更に変更したり展開可能なものである。その一例として、付勢手段はコイルばねSに限られず、板ばねやゴム等の弾性部材であってもよいものである。   Note that the retracting mechanism of the present invention only needs to substantially include the configuration specified in the claims, and the details can be further modified or developed with reference to this form and each modification. As an example, the biasing means is not limited to the coil spring S, and may be an elastic member such as a leaf spring or rubber.
