The stopper support portion 4 is provided on the fixture body 9. The stopper support portion 4 is configured to be able to support the stopper 3. A pair of stopper support portions 4 are provided above and below the stopper 3. As shown in FIG. 4, the stopper support portion 4 has a fixing portion 41 to the fixture main body 9, a shaft fixing portion 42, and a shaft support portion 6. In the stopper support portion 4, the fixing portion 41, the shaft fixing portion 42, and the shaft support portion 6 are integrally formed.

The fixed portion 41 has a flat plate shape and has a flat portion along the front surface of the fixture body 9. The fixing portion 41 is formed with a fixing hole 43 penetrating in the depth direction D. The shaft fixing portion 42 is arranged so as to project forward from the fixing portion 41.

The stopper support portion 4 is provided with a shaft support portion 6. The shaft support portion 6 is a portion that rotatably supports the stopper 3. The shaft support portion 6 projects from the substantially central portion of the shaft fixing portion 42 in a plan view and extends along the vertical direction V. The shaft support portion 6 is a cylindrical shaft member.

The pair of stopper support portions 4 are parts having the same shape. The stopper support portion 4a arranged above the stopper 3 is arranged so that the shaft support portion 6 extends downward from the shaft fixing portion 42. The stopper support portion 4b arranged below the stopper 3 is arranged so that the shaft support portion 6 extends upward from the shaft fixing portion 42.

The stopper support portions 4a and 4b are provided at the front end 95 of the fixture body 9 and at the end portion in the width direction W. As shown in the horizontal cross-sectional view of FIG. 3, a vertical groove 97 extending in the vertical direction V is formed in the front end portion 96 of the member constituting the side wall 92 of the fixture body 9. The vertical groove 97 is formed with a slit 99 that opens to the front side. The length W99 of the slit 99 in the width direction W is shorter than the length W97 of the vertical groove 97 in the width direction W.

The support receiving member 8 is arranged in the vertical groove 97. 5 and 6 show a schematic view of an example of the support receiving member 8. The support receiving member 8 is a member having a substantially flat plate shape, and a screw hole 81 is formed in the central portion of the flat plate. As shown in FIGS. 5 and 6, the support receiving member 8 is a flat plate-shaped member having a hexagonal front view and having a vertical dimension longer than a horizontal dimension. The thickness of the support receiving member 8 is slightly smaller than the dimension of the vertical groove 97 in the depth direction D. Therefore, the support receiving member 8 can be slidably moved in the vertical groove 97.

In the support receiving member 8, the vertical edge portions 82 at both ends in the width direction W extend in parallel. The horizontal edge 83 of the upper and lower ends of the vertical direction V of the support receiving member 8 extends in parallel. Between the vertical edge portion 82 and the horizontal edge portion 83, a corner portion 85 intersecting at a substantially right angle and an inclined edge portion 84 are formed. The corner portions 85 are provided at positions symmetrical with respect to the screw holes 81. The inclined edge portion 84 is located on the side opposite to the corner portion 85 in the width direction W, and is provided at a position symmetrical with respect to the screw hole 81. Inclined edges 84 extend parallel to each other.

The dimension L82 between the vertical edge portions 82 of the support receiving member 8 is shorter than the length W99 in the width direction W of the slit 99. The length L83 between the horizontal edge portions 83 in the vertical direction V is longer than the length W99 in the width direction W of the slit 99. The length L84 between the inclined edge portions 84 is longer than the length W99 in the width direction W of the slit 99 and shorter than the length W97 in the width direction W of the vertical groove 97. Therefore, as shown in FIG. 5, when the support receiving member 8 is arranged at a position where the vertical edge portion 82 is along the vertical direction V, the support receiving member 8 can be inserted into the vertical groove 97 from the front through the slit 99. On the other hand, as shown in FIG. 6, when the support receiving member 8 is rotated around the screw hole 81, the inclined edge portion 84 comes into contact with the inner wall of the vertical groove 97 facing the width direction W. In this state, the support receiving member 8 does not come out ahead of the slit 99. Therefore, when the slit 99 is sandwiched between the support receiving member 8 and the fixing portion 41 of the stopper supporting portion 4, and the screws are inserted into the screw holes 81 and fastened, the fixing portion 41 can be fixed to the front surface of the fixture body 9. With this configuration, the stopper support portion 4 can be fixed at an arbitrary position in the vertical direction V of the fixture body 9.

The stopper 3 is a member arranged in front of the drawer 7 when the drawer 7 is locked. As shown in FIGS. 1 to 4, the stopper 3 is a plate material having a rectangular shape when viewed from the front. The stopper 3 may have, for example, the same material and the same color as the fixture body 9. The details of the operation of the stopper 3 will be described later.

The stopper 3 has a vertical dimension that covers one or more drawers 7 among the plurality of drawers 7, and has a vertical dimension that does not cover the front surface of the remaining one or more drawers 7. The stopper 3 has a length in the vertical direction shorter than the length of the vertical V from the upper stage to the lower stage of the plurality of drawers 7. That is, the stopper 3 is arranged so that one or more of the plurality of drawers 7 can always be opened.

In the example shown in FIGS. 1 and 2, the stopper 3 has a height dimension that can be arranged in front of the upper three drawers 7a, 7b, 7c including the uppermost drawer 7a. The stopper 3 has a vertical dimension substantially equal to the length from the upper end of the uppermost drawer 7a in the vertical direction V to the lower end of the third drawer 7c.

As shown in FIG. 1, the length of the stopper 3 in the width direction W is shorter than the length of the drawer 7 in the width direction W. The stopper 3 covers a part of the front of the drawer 7 in the width direction W. In this way, since the entire front surface of the drawer 7 is not covered, the locked drawer 7 can be visually recognized from the outside at the time of locking. As a result, for example, when the front plate is made of a transparent member or the like, or when the drawer 7 is provided with a window or a slight gap so that the inside of the box can be seen, the drawer 7 can be seen from the outside. In some cases, the stored items can be visually confirmed from the outside even when locked. In addition, the weight of the stopper 3 can be reduced and the cost can be reduced. In addition, although the stopper 3 can rotate around the shaft support portion 6, the flow line of the stopper 3 due to the rotation can be suppressed to a small size. That is, since the length of the stopper 3 in the width direction W is shorter than the length of the drawer 7, even when the stopper 3 is rotated to a position that does not hinder the advance / retreat of the drawer 7 at the time of unlocking, the circumference of the cabinet 1 The stopper 3 does not protrude significantly and does not interfere with the flow line of the user of the cabinet 1.

The stopper 3 is pivotally supported by the shaft support 6 of the stopper support 4. Shaft insertion holes 31 are opened on the upper surface and the lower surface of the stopper 3. The shaft insertion hole 31 is a circular opening having a diameter slightly larger than the diameter of the shaft support portion 6. By inserting each shaft support 6 into the upper and lower shaft insertion holes 31, the stopper 3 is rotatably supported around the shaft support 6. The stopper 3 is provided so as to be movable between a locking position located in front of one or more drawers 7 and restricting the forward movement of the drawer 7 and an unlocking position avoiding the front of the drawer 7. There is.

The stopper 3 rotatably attached around the shaft support 6 is located between the locking position located in front of the drawer 7 and restricting the forward movement of the drawer 7 and the unlocking position avoiding the front of the drawer 7. It is provided so that it can be moved.

The lock portion 5 is configured so that the drawer 7 can be locked by holding the stopper 3 at the locked position. The locking portion 5 includes a known locking portion main body 51, a key (not shown), and a locked portion 52. The locking portion main body 51 includes a lock bar 53 (see FIG. 4). When the key is inserted into the keyhole of the locking portion main body 51 and rotated, the lock bar 53 is configured to move in the width direction W.

The locking portion main body 51 is fixed in the upper frame 93 of the fixture main body 9. The upper frame 93 is formed with a key insertion hole and a locking hole 55. The locking unit main body 51 is inserted into the key insertion hole, and the key hole into which the key is inserted is exposed to the outside. A locking hole 55 penetrating in the depth direction D is formed in the upper frame 93 in the vicinity of the key insertion hole.

The locked portion 52 is attached to the stopper 3. As shown in FIGS. 2 to 4, the locked portion 52 is provided on the back surface of the stopper 3. The locked portion 52 is configured to be lockable with the lock bar 53 of the locking portion 5. The locked portion 52 has a flat plate shape that projects rearward from the back surface of the stopper 3 in the depth direction D. The locked portion 52 is formed with a through hole 54 penetrating in the width direction W, which is the plate thickness direction of the locked portion 52.

Next, an example of how the locking unit 2 is attached to the fixture body 9 will be described.
A pair of stopper support portions 4a and 4b are attached to the fixture body 9 to support the stopper 3.

The support receiving member 8 is provided so as to be slidable in the vertical groove 97 in the vertical direction V. The height of the support receiving member 8 is positioned according to the height position of the drawer 7 to be locked, and the stopper support portion 4 is rotated in the vertical groove 97 to be temporarily locked in the vertical direction V. In this state, the screw 120 is inserted into the fixing portion 41 of the stopper support portion 4 and the screw hole 81 of the support receiving member 8 from the front. Next, when the screw 120 is tightened, the slit 99 is sandwiched between the fixing portion 41 and the support receiving member 8, and the stopper supporting portion 4 is fixed to the fixture body 9. With this configuration, the height position of the stopper support portion 4 can be changed according to the height position where the stopper 3 is provided.

The stopper 3 can be installed at a position corresponding to any drawer 7 among the plurality of drawers 7. That is, the stopper can be provided at the position of any drawer 7 set by the user among the plurality of drawers 7. For example, as in the example shown in FIG. 1, when the drawers 7a to the third drawer 7c in the uppermost stage are the drawers to be locked, or as in the example shown in FIG. 7, the drawers 7a and 2 in the uppermost stage The stopper 3 can be provided at an arbitrary height position as in the case where the drawer 7b of the step is to be locked. In addition, for example, when only the third drawer 7c is to be locked, the stopper 3 can be provided only at the height position corresponding to the third drawer 7c. Therefore, the locking unit 2 can be flexibly provided according to the needs of the user.

By the above method, the lower stopper support portion 4b is first fixed to the fixture body 9. After that, the shaft insertion hole at the lower part of the stopper 3 is inserted into the shaft support portion 6 of the stopper support portion 4b. Next, the shaft support portion 6 of the upper stopper support portion 4a is inserted into the shaft insertion hole 31 above the stopper 3, and the upper stopper support portion 4a is fixed to the fixture body 9 by the above method. As a result, the stopper 3 is fixed to the fixture body 9 via the stopper support portion 4 and the support receiving member 8. The stopper 3 is attached to the fixture body 9 so as to be rotatable between the locking position and the unlocking position with the shaft support portion 6 as the center.

When the stopper 3 is arranged at the locked position, the back surface of the stopper 3 faces the front surface of the drawer 7, and the locked portion 52 enters the locking hole 55 of the upper frame 93. In this state, when the key is inserted into the keyhole of the locking portion main body 51 and the locking operation is performed, the lock bar 53 moves in the width direction W and enters the through hole 54 of the locked portion 52. As a result, the stopper 3 is locked to the upper frame 93 via the lock bar 53 and the locked portion 52, and the rotation of the stopper 3 is restricted. The stopper 3 is held at the locked position. That is, the state in which the stopper 3 is arranged in front of the drawer 7 is maintained, the movement of the drawer 7 to the front is restricted, and the drawer 7 is locked.

In this way, a plurality of drawers 7a, 7b, and 7c can be locked with a single locking operation. On the other hand, in the lowermost drawer 7d, since the stopper 3 is not arranged in front, the drawer 7 can always be opened and closed.

The stopper 3 may be arranged in front of the drawer 7 to restrict the forward movement of the drawer 7. Therefore, the vertical dimension of the stopper 3 may be arranged in a range that hinders the forward movement of the drawer 7 to be locked, and it is not necessary to provide the stopper 3 over the entire area V in the vertical direction from the upper end to the lower end of the drawer 7 to be locked. .. If the stopper 3 is provided at a position that covers at least a part of the front plate of the drawer 7, it has an effect of restricting the movement.

On the other hand, when unlocking the drawer 7, when the user inserts the key into the keyhole of the locking portion main body 51 and unlocks the drawer 7, the lock bar 53 moves toward the locking portion main body 51 in the width direction W. As a result, the lock bar 53 comes out of the through hole 54 of the locked portion 52. In this state, the user rotates the stopper 3 to the unlocked position. The stopper 3 is rotated until the back surface is located outside the front of the drawer 7. As a result, the movement restriction of the drawer 7 is lifted, and the drawer 7 can move forward. The unlocking position may be at least a position where the drawer 7 can be moved forward. For example, it may be a position extending forward along the side wall 92 of the fixture body 9, a position extending in the width direction W along the front surface of the fixture body 9, a position where the stopper 3 faces the side surface of the fixture body 9, and the like. ..

As shown in FIG. 9, after the stopper support portion 4B is attached to the front end portion 96 of the fixture body 9, the front of the slit 99 is covered with the cover member 113. When the slit 99 is covered with the cover member 113, a simple appearance can be obtained. Since the stopper support portion 4B of this modification has the vertical portion 422 on the shaft fixing portion 42B, the stopper support portion 4B can be attached without interfering with the cover member 113. Therefore, the same cover member 113 can be used regardless of the stopper support portion and the mounting position of the stopper.

According to the locking unit 2B of this modification, the stopper support portion 4B can be attached to an arbitrary position at the front end of the fixture body 9 as in the above embodiment. Further, the stopper support portion 4B can be detachably attached to the fixture body 9. Therefore, the stopper 3 can be easily selected and replaced according to the needs of the user.

In the above embodiment, an example of a plate-shaped stopper has been shown, but the form of the stopper is not limited to this, and any structure may be used as long as the advance of the drawer 7 can be regulated. For example, as in the modified example shown in FIG. 10, a long rod-shaped stopper 3C may be used. The stopper 3C of this modification is composed of a base portion 32 extending along the shaft support portion 6 and a restricting portion 33 bent from the base portion 32. The upper and lower bases 32 of the stopper 3C are provided along the shaft support 6, respectively, and the regulating portion 33 is provided in the middle portion of the stopper 3C in the vertical direction V. When the base portion 32 rotates about the shaft support portion 6, the regulating portion 33 rotates. When the locking portion 5B is locked at the locking position where the regulating portion 33 is arranged in front of the drawer 7, the rotation of the stopper 3C is restricted. As a result, the stopper 3C is held at the locked position, and the drawer 7 is locked.

The locked portion 52C is fixed to the base portion 32 above the stopper 3C. The locked portion 52C is provided with a locked portion 52C having the same configuration as that of the above embodiment on the back surface of the plate-shaped connecting member 521. The locking unit 5 and the locking mode are the same as those in the above embodiment. In addition, the locking portion may restrict the rotation of the base portion 32 and the shaft support portion 6 by a known configuration. For example, at the connecting portion between the upper or lower portion of the stopper 3C and the shaft support portion 6, a protrusion that regulates the rotation of the base portion 32 with respect to the shaft support portion 6 is projected by a locking or unlocking operation to restrict the rotation of the base portion 32. Deregulate.

According to the locking unit 2C of the present modification, as in the above embodiment, one locking unit main body 51 can lock any number of drawers 7 at any position. Since the stopper 3C has a rod shape, further weight reduction can be realized. Since the stopper 3C has a rod shape, the stopper 3C is inconspicuous in appearance, and the cabinet 1 having excellent design can be provided.

The mode in which the stopper support portion is attached to the fixture body 9 is not limited to the mode of the above-described embodiment and the modified example. For example, a plurality of screw holes may be formed in the front end portion of the fixture body in the vertical direction V, and the fixture may be directly fixed to the fixture body with screws from any screw hole.

In the above embodiment, an example in which the fixture main body 9 caster 110 and the handle 111 are provided is shown, but the caster 110 and the handle 111 are not indispensable configurations.

In the above-described embodiment and modified example, an example in which the drawer 7 is composed of a front plate and a box portion is shown, but a known example can be applied to the form of the drawer 7. The drawer may be, for example, a basket made of resin, metal, or the like.

In the above embodiment, an example in which the locking unit 5 is provided with a key has been shown, but the locking method is not limited to this, and a known locking device can be used. For example, a configuration may be provided in which a mechanical or electronic input unit for inputting numbers and symbols is provided, and the stopper 3 is switched to either a locked state or an unlocked state by inputting a password in the input unit. ..

In addition to this, as long as the gist of the present invention is not deviated, the configuration described in the above embodiment can be selected or changed to another configuration as appropriate.
