Description

[Detailed description of the invention] [Field of industrial application] The present invention is a multi-drawer type cabinet in which drawers are mounted in multiple stages within the main body. This relates to improvements in equipment.

[Conventional technology]

As is known from Japanese Utility Model Publication No. 58-40208 and Japanese Utility Model Application Publication No. 61-59760, the all-lock device for this type of cabinet is generally provided with a vertical rod that can be raised and lowered along the inner surface of the side plate of the cabinet body. By interlocking and connecting a locking rod that locks the drawer to the vertical rod, all the drawers are locked or unlocked as the vertical rod moves up and down. A plate having a lock fixed to its inner surface and rotatably supported at both left and right ends on the inner surface of the side plate of the cabinet body, behind the lock, that is, in a hollow space surrounded by the upper stile and the top plate of the cabinet body. A cross rod having a shape of All the drawers can be locked or unlocked by associating the vertical rods with the vertical movement to move up and down in conjunction with the rotation.

[Problem that the invention attempts to solve]

However, if the vertical beam is raised and lowered by rotating the plate-shaped horizontal beam placed behind the top stile about its axis, as in the past, the dead space below the top plate increases. There was a problem where the vertical width of the upper stile increased. In other words, as the plate-shaped horizontal rod rotates, its flat surface becomes slanted, but since the horizontal rod has a certain width from front to back, its upper edge will touch the bottom surface of the top plate when it is slanted. The horizontal rod itself has to be placed considerably below the top plate to avoid contact, and when the lock is unlocked, the lower edge of the lock is positioned below the bottom surface of the lock. The vertical width of the space required for this increased, and the upper and lower dimensions of the upper stile had to be increased accordingly.

The present invention aims to solve this problem.

[Means for solving problems]

In order to solve this problem, the present invention provides a cabinet in which drawers are installed in multiple stages between the left and right side plates of the cabinet body, and a vertical rod is provided on the inner surface of one or both of the left and right side plates of the cabinet body. It is mounted so that it can be moved up and down, and as the vertical rod moves up and down, a locking rod provided for each drawer stage is rotated on the inside of the side plate of the cabinet main body, and the locking rod is used to lock the locking part on the side of each drawer. The upper stile of the cabinet body is provided with a lock with a key hole facing the front of the upper stile, and the upper stile of the cabinet body is provided with a lock that faces the front side of the upper stile. A horizontal rod having a tip end facing near the upper part of the vertical rod is arranged approximately horizontally at the rear of the lock extending in the direction of the lock, and the horizontal rod moves left and right along its axis as the lock is unlocked and unlocked. The horizontal rod and the rear part of the lock are connected to each other in such a manner that the horizontal rod and the rear part of the lock are connected to each other, and the tip of the horizontal rod is bent to form an inclined part that is inclined in either the up or down direction, so that the horizontal rod can be moved laterally when the lock is operated. An engagement hole for forcibly moving the vertical rod upward or downward in the locking direction at the inclined part of the horizontal rod is attached to the vertical rod or the upper and lower holes interposed between the vertical rod and the horizontal rod. This configuration is provided on a moving lever member.

[Functions and effects of the idea]

With this configuration, the inclined portion formed at the tip of the horizontal rod can be used as an engagement hole provided in the vertical rod or in an engagement hole provided in the vertically movable lever member interposed between the vertical rod and the horizontal rod. When the horizontal beam moves left and right along its axis in response to an unlocking operation from the front of the upper stile, the vertical beam is directly pushed up or down by the inclined part of the horizontal beam, Alternatively, when the inclined portion engages with the engagement hole of the lever member, the lever member can be moved up and down, thereby indirectly pushing up or lowering the vertical rod.

Therefore, when all the drawers are pushed in and locked, the horizontal rod moves horizontally along its axial direction to move the vertical rod to a locked position, and all the drawers are locked so that they cannot be pulled out. On the other hand, when the drawers are unlocked from the locked position, the horizontal rod moves in the opposite direction to the above to move the vertical rod to an unlocked position, and all the drawers are unlocked and can be pulled out.

In this way, the present invention locks and unlocks all the drawers at the same time by moving the left and right horizontally elongated horizontal bars arranged horizontally behind the upper frame of the cabinet body along their axis. Since the horizontal bars simply move from side to side, they can be installed closer to the bottom surface of the top plate, and the height position of the bottom surface of the horizontal bars remains constant regardless of whether the lock is unlocked or not. The vertical width of the space occupied by the rod can be reduced. Therefore, the dead space below the top plate is reduced and the vertical width of the upper stile can be reduced, which has the effect of improving the design of the cabinet and saving the number of members used for the upper stile and side plates.

〔Example〕

Next, an embodiment of the present invention will be described based on the drawings. In the drawings, reference numeral 1 indicates a drawer (not shown) of three stages mounted between the left and right side plates 3, 3 of the cabinet body 2 so as to be freely forward and backward. The cabinet is made of a thin metal plate, and between the front edges of the left and right side plates 3, 3 of the cabinet body 2, a door 4 is provided at each portion corresponding to each drawer so that the door 4 can be flipped up and rotated, and the door 4 is raised to a horizontal position. The drawer is constructed so that the drawer can be freely pulled out by rotating and being pushed into the cabinet main body 2 along a guide rail (not shown).

Vertical rods 5 having a rectangular cross section are provided on the inner surfaces of the left and right side plates 3 of the main body 2 nearer to the front, and vertical rods 5 having a rectangular cross section are provided so as to be vertically movable. By pivoting the pin 7 to the pin 7 and locking one end of each locking rod 6 to the vertical rod 5 by the pin 8, when the vertical rod 5 rises, the locking portion formed at the other end of the locking rod 6 6a engage with the engaging portions 9 formed on the back surface of each door 4 all at once, locking the drawer so that it cannot be pulled out, and when the vertical rod 5 descends, the engagement is released and the door 4 can be rotated. I am trying to get it unlocked.

Reference numeral 10 denotes a lock fixed to the inner surface of the upper stile 13 of the cabinet body 2, and numerals 12 and 12' denote horizontal rods made of round bars that are horizontally arranged to extend from the rear of the lock 10 in the direction of the side plate 3, respectively. Each shows
The lock 10 has a keyhole facing the front of the cabinet body 2, and a rotary plate 10a provided at the rear end.
Fix the dead bolt 10b in an eccentric state,
Due to the unlocking operation, the dead bolt 10b is locked 10.
The base ends 12a, 12a' of both horizontal rods 12 are connected to the dead bolt 10a via a connecting member 14. The connecting member 14 has a U-shaped cross section,
The flattened proximal ends 12a, 12a' of the horizontal bars 12, 12' are connected to both ends of the base plate with pins 15, so that the horizontal bars 12, 12' and the connecting member 14 are in a substantially linear posture. At the same time, the dead bolt 10b of the lock 10 is inserted and locked into the vertically longitudinal elongated hole 14a bored approximately midway through the substrate of the connecting member 14, and the dead bolt 10b is rotated by the unlocking operation. Along with this movement, both the horizontal rods 12, 12' move laterally along their axis.

In this case, by suspending the middle portions of both horizontal bars 12, 12' at about two locations each with support members 17 that are approximately U-shaped in side view and are fixed to the reinforcing plate 16 of the top plate 11, Although the horizontal posture of the rods 12, 12' is maintained and the horizontal movement is guided, other means may be used to maintain the posture and guide the horizontal movement.

Then, an inclined portion 12c extending diagonally downward is formed on the tip end 12b of the horizontal rod 12 located on the right side of both the horizontal rods 12, 12', while the horizontal rod 12' located on the left side of the cabinet 1 is bent. The tip portion 12b' has a bent inclined portion 12c' extending obliquely upward.

Furthermore, a pin 19 is rotatably attached to the base end portions of lever members 18, 18', which support the vertical rod 5 at their distal ends, to the inner surfaces of the upper end portions of the support members 3, 3'. The vertical rod 5 is configured to move up and down as the lever members 18, 18' move up and down, and
Side plates 18a of these lever members 18, 18',
In the engagement holes 20, 20' drilled in the middle part of 18a',
The inclined portions 12c, 12c' of each of the horizontal rods 12, 12 are exposed.

In the above configuration, when the drawer is pushed into the cabinet body 2 and the door 4 is closed, the lock 10 is opened.
When the lock 10 is locked, the dead bolt 10a of the lock 10 rotates in the direction of the arrow A shown in FIG. In that case, the upper surface of the downwardly inclined portion 12c of the right side rod 12 is the lever member 18 on the right side.
Since the lever member 18 on the right side is engaged with the engagement hole 20 in the middle part, the lever member 18 on the right side is rotated upward by the horizontal movement of the right side horizontal rod 12, and accordingly, the vertical rod 5
rises against its own weight and locks each door 4 unrotatably on the right side, while the upper surface of the upwardly sloped part 12c' of the left side rod 12' touches the left lever member 1.
Since it is engaged with the engagement hole 20' in the middle part of 8', as the left horizontal rod 12' moves in the direction B, the tip of the left lever member 18' also moves upward. As the door 4 is rotated in this manner and the vertical rod 5 attached to the left side plate 3 is raised against its own weight, the door 4 is locked unrotatably on the left side as well.

As both side bars 12, 12' move in the same direction (direction B), the drawer pushed into the cabinet body 2 is locked so that it cannot be pulled out, while the lock 10 is released from the locked state. When the door is unlocked, both the left and right vertical rods 5 move downward due to the opposite action to that described above, and each locking rod 6 is disengaged from each door 4, thereby releasing the lock.

As mentioned above, when unlocking, the horizontal bars 12 and 1
2' simply moves from side to side, these horizontal bars 12, 12' can be provided close to the lower surface of the top plate 11, and accordingly, the mounting position of the lock 10 can also be positioned upward. At the same time, the lower end surfaces of the horizontal bars 12 and 12' are at a constant height regardless of whether the lock is unlocked or not, and there is no unnecessary dead space below the top plate 11. This makes it possible to reduce the vertical width of the upper stile 13 for hiding the frames 12 and 12'. Further, both horizontal rods 12, 12' can be easily formed by bending a round bar or the like, and processing is also simple.

In addition, in the embodiment, the drawer is locked so that it cannot be pulled out by locking the door 4 that is pivotally supported on the main body 2, but in the case of a cabinet in which the drawer is simply mounted, Needless to say, the locking rod may be engaged with and removed from a locking portion provided on the outer surface of the drawer. Further, it is not necessary to lock both the left and right sides of the drawer, and it may be locked only at either the left or right side. Alternatively, the vertical rod may be spring-biased upward and locked as the vertical rod moves downward.
In this case, the direction of movement of the horizontal rod when unlocking may be reversed, or the direction of inclination of the inclined part may be reversed from that in the example (in this case, the lever member should be pushed down on the lower surface of the inclined part). ).

In the embodiment, the horizontal movement of the horizontal rods 12, 12' is converted into the vertical movement of the vertical rods 5, 5 through the lever members 18, 18' pivotally connected to the side plates 3 of the cabinet body 2. Atsutaga, horizontal rod 12, 12'
The inclined portions 12c and 12c' at the other end are connected to the vertical rod 5.
It may be configured such that the vertical rod 5 is directly raised and lowered by the horizontal rods 12, 12' by drilling the side surface of the rod and fitting it into an engagement hole. Furthermore, the shape of the lock is not limited to the embodiments, and the form of the lock is
Like the lock in Publication No. 61-59760, the dead bolt may be provided so as to be slidable left and right with respect to the lock body (in this case, the horizontal bars 12, 12' are attached to the dead bolt). (You can lock it directly).

Furthermore, the horizontal rods may be made of square rods or strips, or if the drawer is to be locked on both the left and right sides as in the embodiment, both horizontal rods may be formed integrally with one round rod or the like. You may do so.

In this way, conventional horizontal rods are formed into a plate shape in order to minimize the turning moment required for locking by keeping the distance from the center of rotation to the position where the dead bolt of the lock contacts a certain distance. However, the horizontal rod in the present invention only needs to have a sloped part at its tip, and can be used with round rods or square rods. It can be made extremely easily by bending a member such as a rod, and it also has the effect of reducing the labor required for processing.
