Description

本発明は、上下に開閉回動する突出体を具えた機器、具体的にはストロボを上下に開閉回動可能に設けたデジタルカメラ等のカメラ機器に関する。   The present invention relates to a device having a projecting body that opens and closes up and down, and more specifically to a camera device such as a digital camera provided with a strobe that can be opened and closed up and down.

図4(a)、(b)は、ストロボを上下回動可能に設けた従来のカメラ機器の側面図である(特許文献1参照)。ストロボランプ(210)を具えたストロボ本体(200)は、キャビネット(100)に設けられた枢軸(220)を中心として上下回動し、該ストロボ本体(200)上に設けられた支持軸(25)に回転アーム(8)の一端部が回動可能に嵌まる。該回転アーム(8)の他端部は、キャビネット(100)に開設された横長の長孔(110)に嵌まる。支持軸(25)にはまた、カム部材(6)がネジリバネ(69)に反時計方向に付勢されて回転可能に嵌まり、該カム部材(6)の先端部は、枢軸(220)に嵌められた付勢バネ(9)の脚片(90)に接する。付勢バネ(9)の他方の脚片(91)はストロボ本体(200)上に設けられたストッパ(26)に接する。
図4(a)に示すように、ストロボ本体(200)が上昇して突出した位置では、脚片(90)とカム部材(6)の接点は、支持軸(25)よりもストロボ本体(200)の先端側に位置する。従って、回転アーム(8)には、ネジリバネ(69)のトルクTに、支持軸(25)から接点までの距離L2に脚片(90)による荷重P2を乗じた反時計方向のトルクが加わる。これにより、回転アーム(8)の他端部は、トルクTよりも大きなトルクで長孔(110)の右端部に圧接され、ストロボ本体(200)のグラ付きが防止される。
一方、図4(b)に示すように、ストロボ本体(200)が下降して閉じた位置では、脚片(90)とカム部材(6)の接点は、支持軸(25)よりもストロボ本体(200)の基端側に位置する。従って、回転アーム(8)にはネジリバネ(69)のトルクTから、支持軸(25)から接点までの距離L1に脚片(90)による荷重P1を乗じた時計方向のトルクを減じたトルクが加わる。従って、使用者がストロボ本体(200)を手で閉じる際に、使用者にはトルクTよりも弱い力が加わり、使用者は弱い力でストロボ本体(200)を閉じることができる。
4 (a) and 4 (b) are side views of a conventional camera device in which a strobe is provided so as to be rotatable up and down (see Patent Document 1). A strobe body (200) having a strobe lamp (210) is rotated up and down around a pivot (220) provided in the cabinet (100), and a support shaft (25) provided on the strobe body (200) is provided. ) Is fitted to one end of the rotary arm (8) in a rotatable manner. The other end of the rotating arm (8) is fitted into a horizontally long slot (110) provided in the cabinet (100). Further, the cam member (6) is urged counterclockwise by the torsion spring (69) and rotatably fitted to the support shaft (25), and the tip of the cam member (6) is attached to the pivot (220). It contacts the leg piece (90) of the biasing spring (9) fitted. The other leg piece (91) of the biasing spring (9) is in contact with a stopper (26) provided on the strobe body (200).
As shown in FIG. 4 (a), at the position where the strobe body (200) is raised and protrudes, the contact between the leg piece (90) and the cam member (6) is closer to the strobe body (200) than the support shaft (25). ). Therefore, counterclockwise torque obtained by multiplying the torque T of the torsion spring 69 by the load L2 from the leg piece 90 to the distance L2 from the support shaft 25 to the contact is applied to the rotary arm 8. As a result, the other end portion of the rotary arm (8) is pressed against the right end portion of the long hole (110) with a torque larger than the torque T, thereby preventing the strobe body (200) from being attached to the grab.
On the other hand, as shown in FIG. 4 (b), when the strobe body (200) is lowered and closed, the contact between the leg piece (90) and the cam member (6) is closer to the strobe body than the support shaft (25). It is located on the base end side of (200). Accordingly, the rotary arm (8) has a torque obtained by subtracting the clockwise torque obtained by multiplying the torque T of the torsion spring (69) by the load P1 by the leg piece (90) to the distance L1 from the support shaft (25) to the contact point. Join. Therefore, when the user closes the strobe body (200) by hand, a force weaker than the torque T is applied to the user, and the user can close the strobe body (200) with a weak force.

特開平6−95219号公報JP-A-6-95219

上記の従来例では、ストロボ本体(200)が閉じた位置では、付勢バネ(9)による荷重が加わっている。従って、カメラ機器の製造業者が、製造工程にてストロボ本体(200)をキャビネット(100)に組み付ける際に、作業性が悪い問題がある。
本発明の目的は、突出体であるストロボ本体が開く過程では荷重を加えるが、閉じた位置では、開き方向に殆ど荷重を加えない付勢体を有する機器を提供することにある。また、ストロボ本体を開く途中に、ストロボ本体を開き方向に付勢する力が、弱い状態から強い状態に切り替わる転換点を任意に設定できることも目的とする。
In the conventional example described above, a load by the biasing spring (9) is applied at the position where the strobe body (200) is closed. Accordingly, there is a problem that workability is poor when a camera device manufacturer assembles the strobe body (200) to the cabinet (100) in the manufacturing process.
An object of the present invention is to provide a device having an urging body that applies a load in the process of opening a strobe body that is a projecting body, but hardly applies a load in the opening direction in a closed position. Another object of the present invention is to be able to arbitrarily set a turning point at which the force for biasing the strobe body in the opening direction is switched from a weak state to a strong state while the strobe body is being opened.

機器は、キャビネット(1)上に開閉回動自在に設けられた突出体と、該突出体を開き方向に付勢する第1の付勢体と、該突出体に取り付けられたカム部材(3)と、該カム部材(3)に接してカム部材(3)を付勢する第2の付勢体を具え、
カム部材(3)は、突出体が開き途中に接する第1カム部(30)と、更なる開き回動時に突出体が接する第2カム部(31)とを連続して具え、
突出体は、突出体の閉じ状態にて第2の付勢体との間で無負荷又は略無負荷状態となる第1の位置と、第1カム部(30)が第2の付勢体に接して第1の付勢体によるトルクを減じる向きの荷重を受ける第2の位置と、第2カム部(31)が第2の付勢体に接して第1の付勢体によるトルクと同じ向きのトルクを生じさせる荷重を受ける第3の位置との間を回動自在に設けられている。
The device includes a protrusion provided on the cabinet (1) so as to be freely opened and closed, a first urging body for urging the protrusion in the opening direction, and a cam member (3 And a second urging body for urging the cam member (3) in contact with the cam member (3),
The cam member (3) includes a first cam portion (30) in contact with the projecting body in the middle of opening and a second cam portion (31) in contact with the projecting body during further opening rotation,
The projecting body has a first position where the projecting body is unloaded or substantially unloaded with the second urging body in the closed state, and the first cam portion (30) is the second urging body. A second position that receives a load in a direction that reduces the torque by the first urging body in contact with the second urging body, and a torque by the first urging body when the second cam portion (31) is in contact with the second urging body. It is rotatably provided between a third position that receives a load that generates torque in the same direction.

突出体の第1の位置、即ち閉じ状態にて、突出体は、第2の付勢体との間で無負荷又は略無負荷状態となる。即ち、突出体は第2の付勢体から殆ど付勢力を受けない。これにより、突出体を閉じ状態でキャビネット(1)に取り付ける際の作業性が良くなる。
突出体が開いて、第2の位置に達すると、第1カム部(30)が第2の付勢体に接して第1の付勢体によるトルクを減じる向きの荷重を受ける。即ち、突出体を開く向きのトルクは小さくなる。これにより、突出体を開いた当初に、突出体が急に開くことが防止される。
更に、突出体が開いて、第3の位置に達すると、第2カム部(31)が第2の付勢体に接して第1の付勢体によるトルクと同じ向きのトルクを生じさせる荷重を受ける。即ち、突出体を開く向きのトルクは大きくなる。これにより、突出体は最後まで確実に開くことができる。
また、突出体を付勢するトルクは、第1カム部(30)と第2カム部(31)との交点を転換点として、大きさが変わる。両カム部(30)(31)はカム部材(3)に形成されており、交点の位置を設計的に容易に変更することができる。
In the first position of the projecting body, that is, in the closed state, the projecting body is unloaded or substantially unloaded with the second urging body. That is, the protruding body receives almost no urging force from the second urging body. Thereby, workability | operativity at the time of attaching to a cabinet (1) in the state which closed the protrusion is improved.
When the projecting body opens and reaches the second position, the first cam portion (30) comes into contact with the second urging body and receives a load in a direction that reduces the torque by the first urging body. That is, the torque in the direction of opening the protrusion is reduced. This prevents the projecting body from opening suddenly when the projecting body is opened.
Further, when the projecting body opens and reaches the third position, the load that causes the second cam portion (31) to come into contact with the second urging body and generate a torque in the same direction as the torque by the first urging body. Receive. In other words, the torque in the direction of opening the protrusion is increased. Thereby, a protrusion can be reliably opened to the last.
Further, the magnitude of the torque that biases the protruding body changes with the intersection of the first cam portion (30) and the second cam portion (31) as a turning point. Both cam portions (30) and (31) are formed on the cam member (3), and the position of the intersection can be easily changed by design.

以下、本発明の一実施例を図を用いて、詳述する。
図1(a)、(b)は、本願に係わる突出体を具えた機器、具体的にはストロボを上下回動自在に具えたカメラ機器の斜視図であり、(a)はストロボ本体(2)が上向きに突出した開き状態を、(b)はストロボ本体(2)が下向きに閉じた状態を夫々示す。
キャビネット(1)の前面からは、周知の如く、鏡筒(10)が突出し、以下の記載では鏡筒(10)の撮影方向を前方、逆方向を後方とする。キャビネット(1)上にて鏡筒(10)の上方に、ストロボ本体(2)が枢軸(20)を中心として回動可能に設けられている。枢軸(20)はキャビネット(1)上に立てられた軸受け(11)に嵌まっている。
ストロボ本体(2)は先端部下面にストロボランプ(21)を設け、枢軸(20)に嵌められたネジリバネ(7)によって開き方向に付勢されている。即ち、本例に於けるネジリバネ(7)は、図4(a)、(b)に示した付勢バネ(9)とは異なり、常にストロボ本体(2)を開き方向に付勢する第1の付勢体である。ストロボ本体(2)は一側部又は両側部にレバーである板状のカム部材(3)を設け、本例ではこのカム部材(3)に1つの特徴がある。
尚、ストロボ本体(2)を閉じ状態でキャビネット(1)へ組み付ける時に、ネジリバネ(7)の一方の脚片をストロボ本体(2)を閉じた後に、キャビネット(1)に係止させて、ネジリバネ(7)の開き方向の付勢力が加わらないようにすることができる。
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
1 (a) and 1 (b) are perspective views of a device provided with a projecting body according to the present application, specifically, a camera device provided with a strobe so that the strobe can be turned up and down. FIG. ) Shows an open state protruding upward, and (b) shows a state where the strobe body (2) is closed downward.
As is well known, the lens barrel (10) protrudes from the front surface of the cabinet (1). In the following description, the photographing direction of the lens barrel (10) is the front and the reverse direction is the rear. A strobe body (2) is provided on the cabinet (1) above the lens barrel (10) so as to be rotatable about a pivot (20). The pivot (20) is fitted into a bearing (11) which stands on the cabinet (1).
The strobe body (2) is provided with a strobe lamp (21) on the lower surface of the tip, and is urged in the opening direction by a torsion spring (7) fitted to the pivot (20). That is, unlike the biasing spring (9) shown in FIGS. 4 (a) and 4 (b), the torsion spring (7) in this example always biases the strobe body (2) in the opening direction. It is an energizing body. The strobe body (2) is provided with a plate-like cam member (3) as a lever on one side or both sides, and this cam member (3) has one feature in this example.
When assembling the strobe body (2) to the cabinet (1) in a closed state, one leg piece of the torsion spring (7) is locked to the cabinet (1) after the strobe body (2) is closed, and the torsion spring It is possible to prevent the biasing force in the opening direction of (7) from being applied.

ストロボ本体(2)は閉じ状態で、キャビネット(1)の上面に設けられたストロボ受け片(4)に受けられ、該ストロボ受け片(4)はストロボ本体(2)の基端部から前方に延びる。ストロボ本体(2)の基端部からは、ストロボ受け片(4)よりも下側に位置する庇板(40)が後方に突出する。
ストロボ受け片(4)にはロック爪(41)が設けられ、ストロボ本体(2)の閉じ状態では、ネジリバネの付勢力に抗して、ロック爪(41)がストロボ本体(2)を係止する。
The strobe body (2) is closed and is received by a strobe receiving piece (4) provided on the upper surface of the cabinet (1). The strobe receiving piece (4) is forward from the base end of the strobe body (2). Extend. From the base end portion of the strobe body (2), a collar plate (40) located below the strobe receiving piece (4) projects backward.
The flash receiving piece (4) is provided with a lock claw (41). When the strobe body (2) is closed, the lock claw (41) locks the strobe body (2) against the biasing force of the torsion spring. To do.

図2(a)、(b)は、図1(a)、(b)の左側面図である。庇板(40)には、薄手の金属板を折曲して形成される付勢体(5)が取り付けられ、該付勢体(5)は上向きに膨らんだ円弧状に形成された板バネ(50)と、庇板(40)に嵌まる嵌合板(51)と、キャビネット(1)の上面にネジ(53)止めされる止め板(52)を一体に具えている。ストロボ本体(2)の回動時には、カム部材(3)の周縁が、板バネ(50)の円弧面に接する。即ち、付勢体(5)はカム部材(3)の周縁に接する第2の付勢体である。
カム部材(3)の周縁は、カム面(32)を形成し、該カム面(32)は枢軸(20)と略同心の円弧状に形成された第1カム部(30)と、第1カム部(30)よりもストロボ本体(2)の閉じ側、即ち時計方向側に位置する直線状の第2カム部(31)を連続して形成している。第1カム部(30)と第2カム部(31)の交点をKとする。
2 (a) and 2 (b) are left side views of FIGS. 1 (a) and 1 (b). An urging body (5) formed by bending a thin metal plate is attached to the saddle plate (40), and the urging body (5) is a leaf spring formed in an arcuate shape swelled upward. (50), a fitting plate (51) that fits into the gutter plate (40), and a stop plate (52) that is secured to the top surface of the cabinet (1) by screws (53). When the strobe body (2) is rotated, the periphery of the cam member (3) is in contact with the arc surface of the leaf spring (50). That is, the urging body (5) is a second urging body in contact with the peripheral edge of the cam member (3).
The peripheral edge of the cam member (3) forms a cam surface (32). The cam surface (32) has a first cam portion (30) formed in an arc shape substantially concentric with the pivot (20), and a first cam portion (3). A linear second cam portion (31) is continuously formed so as to be located closer to the closing side of the strobe body (2) than the cam portion (30), that is, to the clockwise direction. Let K be the intersection of the first cam portion (30) and the second cam portion (31).

図2(a)に示すように、ストロボ本体(2)が閉じ状態にあるときには、カム部材(3)の第1カム部(30)は板バネ(50)から僅かに離れている。ストロボ本体(2)のキャビネット(1)への組み付け時には、ネジリバネ(7)の付勢力が加わらないようにすることができるから、この状態では、板バネ(50)から付勢力を受けない無負荷状態となっている。これを第1の位置とする。
ストロボ本体(2)をキャビネット(1)に組み付け、ネジリバネ(7)を正しく取り付けた状態で、ロック爪(41)の係止を解除して、ストロボ本体(2)を開くと、第1カム部(30)が板バネ(50)に接して板バネ(50)から上向きの付勢力を受ける。これを第2の位置とする。
この場合、図3(a)に示すように、カム部材(3)には枢軸(20)に嵌められたネジリバネ(7)による反時計方向のトルクTが当初から加わっているが、これに加えて、板バネ(50)から受ける付勢力P1に該P1から枢軸(20)までの距離L1を乗じたトルクT1が作用する。付勢力P1を延長した仮想線は枢軸(20)よりも左側を通るから、該トルクT1はトルクTと反対側の時計方向であり、ストロボ本体(2)を付勢するトルクは
T−T1=T−P1×L1
となり、ネジリバネ(7)によるトルクTよりも小さくなる。これにより、ロック爪(41)による係止を解除して、ストロボ本体(2)を開いた当初に、ストロボ本体(2)が急に開く向きに飛び出すことが防止される。即ち、板バネ(50)はダンパとしての役割を有する。
As shown in FIG. 2 (a), when the strobe body (2) is in the closed state, the first cam portion (30) of the cam member (3) is slightly separated from the leaf spring (50). When assembling the strobe body (2) to the cabinet (1), it is possible to prevent the biasing force of the torsion spring (7) from being applied. In this state, no load is applied without receiving the biasing force from the leaf spring (50). It is in a state. This is the first position.
When the strobe body (2) is assembled to the cabinet (1) and the torsion spring (7) is correctly attached, the lock claw (41) is released and the strobe body (2) is opened. (30) contacts the leaf spring (50) and receives an upward biasing force from the leaf spring (50). This is the second position.
In this case, as shown in FIG. 3 (a), a counterclockwise torque T is applied to the cam member (3) by a torsion spring (7) fitted to the pivot (20) from the beginning. Thus, a torque T1 obtained by multiplying the urging force P1 received from the leaf spring (50) by a distance L1 from the P1 to the pivot (20) acts. Since the imaginary line in which the urging force P1 is extended passes on the left side of the pivot (20), the torque T1 is in the clockwise direction opposite to the torque T, and the torque for urging the strobe body (2) is T−T1 = T-P1 × L1
Thus, it becomes smaller than the torque T by the torsion spring (7). Thus, when the flash claw (41) is released and the strobe main body (2) is opened, the strobe main body (2) is prevented from jumping out in a sudden opening direction. That is, the leaf spring (50) has a role as a damper.

図2(b)に示すように、ストロボ本体(2)を更に開き、交点Kを通過して、第2カム部(31)が板バネ(50)に接すると、板バネ(50)から上向きの付勢力を受ける。これを第3の位置とする。第2カム部(31)は直線状であり、図3(b)に示すように、板バネ(50)から受ける付勢力P2を延長した仮想線は枢軸(20)よりも右側を通る。従って、付勢力P2に該P2から枢軸(20)までの距離L2を乗じたトルクT2はトルクTと同じく反時計方向であり、ストロボ本体(2)を付勢するトルクは
T+T2=T+P2×L2
となり、ネジリバネ(7)によるトルクTよりも大きくなる。これにより、ストロボ本体(2)が最後まで確実に開くことができる。また、直線状の第2カム部(31)が板バネ(50)と突っ張るように接するから、ストロボ本体(2)が開き完了した状態で、グラ付くことが防止される。
上記の如く、ストロボ本体(2)を付勢するトルクは、交点Kを転換点として、大きさが変わる。両カム部(30)(31)は板状のカム部材(3)の周縁に形成されており、交点Kの位置を設計的に容易に変更することができる。例えば、ストロボ本体(2)の開き完了直前まで、ストロボ本体(2)を付勢するトルクをトルクTから減じるように設定することもできる。
As shown in FIG. 2 (b), when the strobe body (2) is further opened and the second cam portion (31) is in contact with the leaf spring (50) after passing through the intersection K, the leaf spring (50) is directed upward. Receive the energizing power of This is the third position. The second cam portion (31) is linear, and as shown in FIG. 3 (b), the imaginary line extending the urging force P2 received from the leaf spring (50) passes to the right of the pivot (20). Therefore, the torque T2 obtained by multiplying the urging force P2 by the distance L2 from the P2 to the pivot (20) is counterclockwise like the torque T, and the torque for urging the strobe body (2) is T + T2 = T + P2 × L2.
Thus, it becomes larger than the torque T by the torsion spring (7). Thereby, the strobe body (2) can be reliably opened to the end. Further, since the linear second cam portion (31) is in contact with the leaf spring (50) so as to be stretched, it is possible to prevent the flash body from sticking when the strobe body (2) is completely opened.
As described above, the torque for energizing the strobe body (2) changes in magnitude with the intersection K as a turning point. Both cam portions (30) and (31) are formed on the periphery of the plate-like cam member (3), and the position of the intersection K can be easily changed in design. For example, the torque for urging the strobe body (2) may be set to be reduced from the torque T until just before the strobe body (2) is opened.

本例にあっては、ストロボ本体(2)が閉じ状態にあるときに、カム部材(3)の第1カム部(30)は板バネ(50)から僅かに離れており、ネジリバネの付勢力が加わらないようにすれば、無負荷状態となっている。従って、カメラ機器の製造業者が、製造工程にてストロボ本体(2)をキャビネット(1)に組み付ける際に、板バネ(50)から付勢力を受けることはなく、組立作業性がよい。
ここで、ストロボ本体(2)が閉じ状態にあるときには、無負荷状態となっているとしたが、略無負荷状態であってもよい。この略無負荷状態とは、カム部材(3)の第1カム部(30)は板バネ(50)に接しているが、板バネ(50)が撓まない又は殆ど撓まず、板バネ(50)から付勢力を殆ど受けていない状態を指す。この無負荷状態でも、ストロボ本体(2)の組立作業性及びストロボ本体(2)を閉じる際の操作性が改善される。
In this example, when the strobe body (2) is in the closed state, the first cam portion (30) of the cam member (3) is slightly separated from the leaf spring (50), and the biasing force of the torsion spring If it is made not to add, it will be in a no-load state. Therefore, when the camera device manufacturer assembles the strobe body (2) to the cabinet (1) in the manufacturing process, it does not receive a biasing force from the leaf spring (50), and the assembly workability is good.
Here, when the strobe body (2) is in the closed state, it is in the no-load state, but it may be in a substantially no-load state. This substantially no-load state means that the first cam portion (30) of the cam member (3) is in contact with the leaf spring (50), but the leaf spring (50) is not bent or hardly bent, and the leaf spring ( This refers to the state that receives almost no urging force from 50). Even in this no-load state, the assembly workability of the strobe body (2) and the operability when closing the strobe body (2) are improved.
