Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a lock device for locking an opening / closing member moved to a closed position and moored to a storage device main body at the closed position, and more particularly to a lock device with a simplified structure.
[0002]
[Prior art]
For example, many drawer-type storage furniture in the related art are provided with a lock device that locks a drawer that is moved to a closed position and is moored to the storage device main body at the closed position.
[0003]
This lock device converts the operation of an advance / retreat member that moves forward / backward by a key operation into a rotation operation of an operating body via a transmission element such as a link mechanism, and converts the operating body into an engagement provided on the storage device body side. By selectively engaging the drawer with the portion in the closed position of the drawer, a locked state in which the opening operation of the drawer is prohibited as necessary is realized.
[0004]
[Problems to be solved by the invention]
However, in such a case, by appropriately configuring the transmission element such as the link mechanism, even if there is a gap in the space between the place where the cylinder lock or the like is arranged and the place where the operating body is arranged, the operation amount can be reduced. While transmission is possible, the presence of such a transmission element increases the number of parts and unavoidably expands the space.Therefore, there are many restrictions on the installation space of the drawer, and there are more causes of malfunction. Become.
[0005]
In particular, this type of lock device is often applied to the uppermost drawer of a plurality of drawers, and the uppermost drawer has a shallower bottom and a lower height than other drawers. There are not a few small forms. For this reason, many locking devices incorporated in such drawers are incompatible with conventional devices.
[0006]
The present invention has been made in view of such a problem, and aims to newly provide a lock device that can be incorporated in a storage device as compactly as possible.
[0007]
[Means for Solving the Problems]
The present invention employs the following means to achieve the above object.
[0008]
That is, when the lock device of the present invention is moved to the closed position to lock the open / close member moored to the storage device main body at the closed position, the surface provided on the open / close member side and orthogonal to the open / close direction along with the key operation. A locking mechanism provided with a reciprocating member operating inside thereof, a locking mechanism protruding in the opening and closing direction at a position adjacent to the locking mechanism, and being directly driven by the reciprocating member to rotate between the open position and the engagement position around the first axis. An actuating body rotatable between the actuating body and the actuating body in the open position when the opening / closing member moves to the closed position at the corresponding position of the actuating body on the storage device body side, and is engageable at the standby position; and An actuated body rotatable about a second axis parallel to the first axis by the actuated body after the engagement, and when the actuated body is rotationally driven and moves from the standby position to the lock position. The opening and closing member Or wherein the indirectly so that lock to the storage body.
[0009]
According to such a configuration, it is possible to dispose the operating body immediately near the locking mechanism, and to dispose the actuated body immediately behind the operating body when the opening / closing member moves to the closed position. For this reason, at least the portion from the opening / closing member to the transmission of the lock operation force to the storage device main body can be locally concentrated and configured, and the lock device can be effectively incorporated even in a narrow space.
[0010]
When the opening / closing member moved to the closed position is moored to the storage device main body by the latch mechanism configured between the opening / closing member and the storage device main body, the actuated body of the lock device is driven to rotate. At this time, it is desirable that the latch mechanism be configured to directly or indirectly engage with a part of the latch mechanism to prohibit release of the latch state.
[0011]
Specifically, when the latch mechanism includes a mooring claw provided on the opening / closing member side and a mooring portion provided on the storage device body side, the operation of disengaging the mooring claw from the mooring portion is selectively allowed or A regulating member is arranged at a position where the actuation is prohibited, and a connection between the actuated body and the regulating member is connected by a transmission member, and the movement of the operated body from the standby position to the lock position via the transmission member is regulated. Is preferably converted to an operation of moving from the allowable position to the prohibited position.
[0012]
A preferred positional relationship is one in which the locking claws of the latch mechanism are arranged in substantially the same plane with the locking mechanism, the operating body and the operated body.
[0013]
When the opening / closing member is moved toward the storage device main body, when the operating body is in the open position, the opening / closing member reaches the closed position and engages with the operated body in the standby position. When the opening / closing member is at the position, it is interfered with the actuated body at the standby position just before reaching the closing position and is prevented from reaching the closing position. It is desirable to provide a safety mechanism for preventing the body from moving from the open position to the engagement position.
[0014]
The safety mechanism is preferably configured such that the opening / closing member comes into contact with a part of the storage device body preferentially before reaching the closed position to release the prohibited state.
[0015]
In order to realize a simple mounting structure, it is preferable that the operating body and the safety mechanism are incorporated in a case to form a unit.
[0016]
As a preferable application example of the present invention, the storage device main body is a housing having an opening in the front, and the opening / closing member is a drawer that can be put in and taken out of the opening, and in particular, the drawer is the uppermost stage. Drawers.

And a pressing member 44 rotatably attached to the center and transmitting the rotating operation of the handle 3 to the second rotating arm 42.
[0023]
The first rotating arm 41 is formed by bending a wire into an L-shape and attached to the left and right front ends of the drawer 2 via first rotating arm attachments 41x, and includes a main body 41a located on the rotating shaft, And a horizontal portion 41b bent from the upper end of the main body 41a. The mooring claw 43 is attached to the lower end of the main body 41a so as to be integrally rotatable, and the tip of the mooring claw 43 is projected rearward from the end plate 22.
[0024]
The second rotary arm 42 is formed by bending a wire into a crank shape to form a main body 42a extending substantially in parallel with the longitudinal direction of the tab 3, and a first rotary arm engaging portion extending substantially vertically downward from one end of the main body 42a. 42b, and a pressing member engaging portion 42c extending substantially vertically upward from the other end of the main body 42a, and is formed in a U-shape in plan view attached to a substrate 45 provided on the plate surface of the end plate 22. The main body 42a is rotatably supported about the axis thereof by a rotary arm fitting 42x.
[0025]
The mooring claw 43 is a plate-shaped member having a hole 43a in the thickness direction on the side of the rear protruding end. As shown in FIG. 7, the penetrating direction of the hole 43a is directed to the inner surface of the side wall 13 of the storage device body 1. It has been set. On the other hand, the mooring portion 10 is attached to the inner surface of the side wall 13 of the storage device main body 1 and has a slope gradually approaching the drawer 2 toward the back. An urging force is applied to the first rotating arm 41 from an urging means such as a torsion coil spring (not shown) to elastically urge the mooring claw 43 in the direction toward the mooring portion 10.
[0026]
As shown in FIGS. 3 to 5, the pressing member 44 is disposed substantially opposite to the plate surface of the end plate 22, and has a main body 44 a having a pressing member engaging portion 42 c of the second rotating arm 42 in contact with the inner surface.

Here, the operation of the latch mechanism 4 of the present embodiment configured as described above will be described with reference to FIG. In the figure, reference numeral 55 denotes a regulating member, but the regulating member 55 will be described later, and is not considered here.
[0028]
First, in a state where the drawer 2 is stored in the storage space, when the puller 3 is operated to be pulled forward by using the concave portion 31 provided in the puller 3 of the drawer 2, the pressing member 44 rotates around the axis m. Then, the main body 44a is rotated in a direction to approach the plate surface of the end plate 22. Then, in conjunction with the rotation operation, the pressing member connecting portion 42c of the second rotating arm 42 is pushed backward, and the second rotating arm 42 rotates around the main body 42a in a direction indicated by an arrow in FIG. The first rotating arm connection part 42b moves forward. Then, the first rotating arm 41 rotates about the main body 41a. As a result, as shown by an arrow in FIG. 7, the direction in which the mooring claw 43 fixed and attached to the main body 41 a of the first rotating arm 41 rotates together with the main body 41 a and separates from the side wall 13 of the storage device main body 1.

Then, by continuously pulling the drawer 2 toward the user, the drawer 2 can be pulled out of the storage space, and articles can be taken in and out of the drawer 2.
[0029]
When the drawer 2 is to be stored in the storage space, the reverse operation may be performed. That is, only by pushing the drawer 2 inward, the mooring claw 43 gradually falls inward when climbing over the slope of the mooring portion 10, and returns to the original posture by the action of a torsion coil spring (not shown) at the overcoming position, and the mooring claw 43 is returned. Moored at 10. In this state, the mooring claw 43 is moored in the hole 10a of the mooring portion 10, so that the situation where the drawer 2 is accidentally moved at the time of an earthquake or moving furniture is reliably prevented.

More specifically, as shown in FIGS. 3, 4, and 8, the locking mechanism 51 is configured by incorporating a cylinder 51b and a reciprocating member 51a in a housing 51h, and is attached to the uppermost drawer 2. The pull-out member 51a, which is disposed adjacent to the right end of the pull handle 3 and located at the right side thereof, turns the axis of the cylinder 51b in the opening and closing direction of the drawer 2 and projects downward from the housing 51a. It is raised and lowered by operation.
[0032]
As shown in FIGS. 4 to 6, the operating body 52 is provided near the left and right ends of the drawer 2 so as to be spaced apart in the width direction of the drawer 2, and has a base end 52 a attached to an interlocking rotating shaft 50 described later. The first and second claws 52b, 52c protrude rearward from the end 52a. The operating body 52 has a plate shape in a plan view in the mounting posture. The first claw 52b extends straight, and the second claw 52c gradually bends and extends in a “C” shape so as to gradually approach the first claw 52b after being separated from the first claw 52b, and has a substantially U-shape as a whole. Has made. The operating body 52 is normally biased by a spring (not shown) and is at an open position P where the first claw 52b is substantially horizontal. 8, the upper surface of the first claw 52b is located at a position where it can be pushed down by the advance / retreat member 51a of the locking mechanism 51 as shown in FIG. It can be driven to rotate to the engagement position Q around 50 turns. The operating bodies 52 are connected to each other via an interlocking rotating shaft 50, and the rotational force applied to the right operating body 52 is transmitted to the left operating body 52 via the interlocking rotating shaft 50. . In order to ensure the transmission of the rotational force, the interlocking rotating shaft 50 has a prismatic shape, and both ends are inserted into square holes provided on the opposing surface of the operating body 52. In particular, the interlocking rotary shaft 50 of the present embodiment is disposed on the axis m of the latch mechanism 4, and the bearing 46 b has a hole for inserting the interlocking rotary shaft 50 at the center at the axial position. It is a formed annular shape.
[0033]
On the other hand, the actuated body 53 is attached to the inner surface of the side wall 13 of the storage device main body 1 so as to be rotatable around a horizontal axis 53a, which is a second axis parallel to the interlocking rotating shaft 50, as shown in FIG. An input end 53b that enters between the first claw 52b and the second claw 52c of the operating body 52, and an output end 53c located on the opposite side of the horizontal shaft 53a from the input end 53b. It has a plate shape with. The actuated body 53 is rotatable between a standby position R in which the input end portion 53b is substantially horizontal and a lock position S in which the input end 53b is inclined forward. It engages with a certain operating body 52, and after the engagement, the operating body 52 rotates to the engagement position Q, so that it is rotated around the horizontal shaft 53 a to the lock position S.
[0034]
The regulating member 55 is formed by bending a plate material into a crank shape and attaching the base end side of the intermediate portion to the inner surface of the side wall 13 of the storage device main body 1 via the horizontal shaft 55a, and inputs the inner end of the storage space. The end 55b is defined as the outer end and the regulation end 55c is defined as the outer end. In order to selectively allow or prohibit the operation of the mooring claw 43 disengaging from the mooring portion 10 in the mooring state, the regulating end 55c disposed at a position slightly raised from the inner surface of the side wall 13 seals the mooring portion 10 with the lid. Between the prohibition position U and the permissible position T where the disengagement is permitted.
[0035]
The transmission member 54 is a plate-like member provided in the inner surface of the side wall 13 of the storage device main body 1 and provided with a vertically extending groove 13a and accommodated in the groove 13a, and is slidable in the vertical direction. The output end 53c of the actuated body 53 is connected to the upper end of the transmission member 54 via a slide engagement portion 54a having a horizontal shaft and a long hole, and a slide member having a horizontal shaft and a long hole is connected to the lower end. The input end 55b of the restricting member 55 is connected via the joint 54b, and the restricting member 55 is allowed to move from the standby position R to the lock position S via the transmitting member 54. Is converted to an operation of moving from the position to the prohibition position U.
[0036]
When the drawer 2 is moved toward the storage device main body 1 under the lock device 5, when the drawer 2 reaches the closed position when the drawer 2 reaches the closed position when the drawer 2 is at the open position P, the operating body 52 is moved to the standby position R. When the drawer 2 is at the engagement position Q, the driven body 53 at the standby position R, mainly the first claw 52b, and the input The portion 53b interferes and is prevented from reaching the closed position. Therefore, in this embodiment, the safety mechanism 6 is provided to prohibit the operation body 52 from moving from the open position P to the engagement position Q while the drawer 2 is not in the closed position.
[0037]
As shown in FIGS. 4, 5, 8, and 9, the safety mechanism 6 includes a movable element 61 which is located adjacent to the operating body 52 and which can be protruded and retracted in the opening / closing direction. A coil spring 62 biasing the movable member 61 is moved from the open position P of the operating body 52 to the engagement position Q when the movable member 61 is at the projecting position V shown in FIG. And a pin 63 for inhibiting rotation toward the movable member 61. The pin 63 is provided on a relief 61a provided in a part of the movable member 61 when the movable member 61 moves to the immersion position W shown in FIG. It can enter and allow the rotation of the operating body 52. The movable element 61 comes into contact with a part of the storage device main body 1 (for example, the front surface of the side wall 13) preferentially before the drawer 2 reaches the closed position, and is immersed, thereby releasing the prohibited state. ing.
[0038]
The operating body 52 and the safety mechanism 6 that constitute the lock device 5 are integrated into a case 7 to form a unit. The case 7 and the housing 51h of the locking mechanism 51 are overlapped and arranged. The reciprocating member 51a of the locking mechanism 51 is protruded downward through a notch 7a provided in the lock mechanism 51.
[0039]
As described above, in the present embodiment, when locking the drawer 2 to the closed position, the locking mechanism 51 provided with the advance / retreat member 51a provided on the drawer 2 and operating in a plane orthogonal to the opening / closing direction in accordance with a key operation. An operation that is provided at a position adjacent to the locking mechanism 51 so as to protrude in the opening and closing direction and is directly driven by the advance / retreat member 51a and rotatable about the interlocking rotation shaft 50 between the open position P and the engagement position Q. The drawer 2 moves to the closed position when the drawer 2 is moved to the closed position at the corresponding position of the body 52 and the operating body 52 on the storage device main body 1 side, and is engageable at the standby position R; After the engagement, there is provided an actuated body 53 rotatable about a horizontal axis 53a parallel to the interlocking rotating shaft 50 by the actuated body 52, and the actuated body 53 is driven to rotate and locked from the standby position R. When moved to location S, it is obtained so as to lock the drawer 2 to the storage body 1.
[0040]
As described above, since the operating body 52 can be arranged in the immediate vicinity of the locking mechanism 51, and the operated body 53 can be arranged in the immediate vicinity of the operating body 52 when the drawer 2 is moved to the closed position. The portion that transmits the lock operation force from the second to the storage device main body 1 can be locally concentrated, and the lock device 5 can be effectively incorporated in a narrow space.
[0041]
In particular, the storage device of this embodiment has a structure in which the drawer 2 moved to the closed position is moored to the storage device body 1 by the latch mechanism 4 configured between the drawer 2 and the storage device body 1. However, using this structure, the lock device 5 is configured to indirectly engage with a part of the latch mechanism 4 to prohibit the release of the latch state when the actuated body 53 is rotationally driven. . For this reason, the latch mechanism 4 and a part of the component parts of the lock device 5 can be used in common, and the number of components of the lock device 5 can be effectively reduced as compared with a case where a lock device is newly formed separately. The overall space factor can also be effectively improved.
[0042]
Specifically, the latch mechanism 4 includes a mooring claw 43 provided on the drawer 2 side and a mooring portion 10 provided on the storage device main body 1 side, and the mooring claw 43 is disengaged from the mooring portion 10. The restricting member 55 is disposed at a position where the operation to selectively perform the operation is selectively permitted or prohibited, and the operating member 53 and the restricting member 55 are connected by the transmission member 54. The operation of moving the lock member 53 from the standby position R to the lock position S is converted into an operation of moving the restricting member 55 from the allowable position T to the prohibited position U. For this reason, even if the mooring claw 43 is separated from the operating body 52, the operating force can be effectively transmitted via the transmitting member 54, and the other mooring claw 43 (not shown) is operated using the transmitting member 54. Since all of the three drawers 2 can be locked at the same time, the necessary lock function can be accurately realized through a simple structure.
[0043]
Further, as is apparent from the drawing, the mooring claws 43 of the latch mechanism 4 are arranged in substantially the same plane (vertical plane) together with the locking mechanism 51, the actuating body 52 and the actuated body 53. Since it is subsumed in a small space, it can be compactly assembled on the right end side of the drawer 2 as shown in the figure, and the present invention can be effectively introduced to a limited part of the assembling space. Can be.
[0044]
Further, in this embodiment, since the safety mechanism 6 for preventing the operating body 52 from moving from the open position P to the engagement position Q while the drawer 2 is not in the closed position is provided, the storage device main body 1 is opened. Even if a key operation is performed by mistake in this state, the movement of the operating body 52 to the engagement position Q is prohibited by the safety mechanism 6, and the operating body 52 collides with the operated body 53 to cause unexpected damage. This can be reliably prevented.
[0045]
In particular, since the safety mechanism 6 releases the prohibition state by preferentially contacting a part of the storage device main body 1 before the drawer 2 reaches the closed position, the safety mechanism 6 has a simple structure and a prohibition area. As a result, the above-described effect can be achieved as large as possible, and at the same time, in the closed position, the prohibited state can be reliably released and the state can be shifted to the lockable state.
[0046]
In addition, in this embodiment, since the operating body 52 and the safety mechanism 6 are incorporated into the case 7 to form a unit, the mounting of the operating body 52 and the safety mechanism 6 in an appropriate positional relationship only by attaching the unit is required. And the assembling work can be simplified.
[0047]
With this configuration, in this embodiment, the storage device main body 1 has a housing shape having an opening at the front, and the opening / closing member is a drawer 2 that can be put in and out of the opening. The lock device 5 of the present invention can be compactly incorporated into a small gap between the drawer 2 (specifically, the end plate 22 thereof) and the storage device main body 1.
[0048]
The lock device 5 is applied to the uppermost drawer 2 of a plurality of drawers. Even if the drawer 2 has a smaller vertical height than that shown in the drawing, the present invention can be applied to the lock device 5. It can be applied effectively.
[0049]
The present invention is also applicable to a storage device having an opening / closing member other than a drawer, for example, a storage device having an opening / closing door or a sliding door as an opening / closing member. Further, the specific configuration of each unit is not limited to only the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
[0050]
【The invention's effect】
The present invention provides, through the above-described configuration, an operation body disposed in the immediate vicinity of a locking mechanism, and an actuated body disposed in the vicinity of a depth of the operation body when the opening / closing member has moved to a closed position, and at least an opening / closing member Since the part from when the lock operation force is transmitted to the storage device main body can be locally aggregated and configured, the application target is the narrow space between the top drawer with a small internal volume and the storage device main body, etc. Even if there is, the lock device can be effectively incorporated in a compact state.
