Abstract

The present invention relates to a drawer cabinet used for a house, an office or the like. More specifically, the drawer cabinet uses an existing control bar moved up and down by a key module provided in the drawer cabinet, while including a control operation unit integrated with or mounted in a side part of each drawer, thus enabling automatic engagement and automatic disengagement with respect to drawers other than the one withdrawn and open due to interference between a control pin of the control bar and the control operation unit, which is caused by the individual withdrawal of the drawers. Thus, the drawer cabinet forms a control operation unit of a relatively simple constitution in a side part of each drawer while using the existing key module and control bar. Therefore, the drawer cabinet can enable drawers to be locked and unlocked at the same time through a key module like an existing method, and moreover, when a specific drawer is withdrawn and open in a state in which each of the drawers is unlocked, the drawer cabinet creates a temporary locking condition by engagement with respect to drawers other than the one withdrawn and open, thus preventing drawers from being unnecessarily withdrawn and open other than a selected drawer. Also, since the drawer cabinet can be prevented from leaning and overturning when all drawers are opened at the same time by the inclination of the drawer cabinet or damage or injury caused by overturning can be prevented, the drawer cabinet can be very economical and efficient.

Description

Drawer cabinet with automatic locking means for drawers other than open}

The present invention relates to a chest of drawers used in homes or offices, and more particularly, when the drawers are individually withdrawn from the upper and lower multi-stage drawers, the remaining drawers other than the drawers are configured to be automatically locked. The present invention relates to a chest of drawers equipped with an automatic locking means for individual drawers to prevent the rest of the drawers from being pulled out and opened and to prevent the drawers from being overturned while all drawers are simultaneously pulled out and opened by the inclination of the drawers.

In general, a chest of drawers is furniture used in homes or offices, and a plurality of drawers that can be individually withdrawn while storing clothes or office supplies and other various household items are made in a stacked top and bottom structure.

Such a drawer allows the opening and closing of the drawer to be determined through various types of locking devices for safe storage of the stored items, and the lock for drawers according to the prior art is usually coupled to one side of the front of the top drawer of the drawer. A key module, an interlocking bar installed up and down on one side inside the body of the drawer, a main deterrent pin protruding from one side of the deterrent bar to interfere with the key module, and a side of each drawer under the main deterrent pin It consists of an individual intermittent pin protruding to correspond to.

According to this conventional configuration, as the elevating pin of the key module rotates by the key, the control bar moves upward due to interference with the main control pin, and the individual control pins of the control bar move upward due to the rise of the control bar. The drawer is simultaneously locked while being simultaneously locked to the locking hole or the locking groove formed on the side of the drawer. As the key is rotated in the unlocking direction, the individual locking pin for each drawer is simultaneously lowered and It has a structure that simultaneously unlocks the drawer while descending.

In other words, as in Registered Utility Model No. 20-0208121, a lever, a pair of hooks, and a pair of hooks, are mounted on the inner wall of a cabinet in which one or more drawers are mounted and move up and down as the moving piece of the key part rotates. In the clasp composed of one or more intermittent pieces, reinforcing ribs protrude forward and rearward between the outer circumferential surface of the lever and each of the clasps and intermittent pieces to provide reinforcement against stress in the up and down directions, and each hanger Reinforcing pieces protruding left and right are formed at the boundary between the levers of the piece and the intermittent piece to provide reinforcing force against the stress in the left and right directions, and all of them are integrally formed by the operation of synthetic resin injection molding. Drawer lock clasps have been devised and registered.

However, the chest of drawers is simultaneously locked and unlocked for all drawers. When a specific drawer is pulled out and opened in the unlocked state for all drawers, the rest of the drawers are pulled out together and open at the same time. In the process of moving or transporting the drawer, all drawers are pulled out and opened at one time, and the drawer is overturned due to the shift of the center of gravity, causing injury to the worker and damage to the drawer.

Accordingly, a main body in which rails are fixedly arranged by dividing the layers into places corresponding to the drawers, as in the recent Korean Patent No. 10-1730417; And, several drawers having independent slide mobility while being guided to the main body rails; And, It consists of a key operation unit that allows entry and exit of the drawer; and a locking member that controls the slide movement of the drawer due to the position change of the key operation unit, but the locking member and the fall prevention on each of the opposite side and the other side of the upper body Including that the means is formed in a one-to-one correspondence, the fall prevention means is interlocked between layers by an individual slide withdrawal action of the drawer in a locked-unlocked state by a key operation unit, so that the locking of the other adjacent drawers is determined. As for the fall prevention means, a fall prevention drawer has been constructed and registered so that a downward movement is induced by an elastic means when switching from a locked state to an unlocked state through a key operation unit.

However, the fall prevention drawer must be provided with a unique locking member, without using the existing control table as it is, and the fall prevention means is composed of complex and many components including elastic means, which incurs excessive production costs. It has a bad thing.

In addition, since the fall prevention means acts due to the mutual organic operating relationship of many components, the service life is extremely short due to frequent failures or damages.

Korea Registered Utility Model 20-0208121 (Registered on October 12, 2000) Korean Patent Registration 10-1730417 (registered on April 20, 2017)

As shown in the figure, in the conventional multi-stage drawer cabinet in which each drawer 110 and 110 ′ is locked or unlocked from the drawer body 100 at the same time, the drawer 110 and 110 ′ are locked. In the unlocked state, certain drawers 110 and 110 ′ are pulled out and opened, and at the same time, the remaining drawers 110 and 110 ′ are configured to be engaged with respect to the drawer body 100, thereby unnecessarily opening the drawers other than opening. At the same time, it plays a role of preventing the drawer from falling over or being damaged or injured by falling, as all drawers are opened at the same time due to inclination or the like.

Accordingly, in the present invention, the drawers 110 and 110 ′ of the upper and lower layers from the front of the drawer body 100 are connected to the drawer body 100 and each of the drawers 110 and 110 ′ through a rail, etc. The key module 120 is mounted on the front of the drawer 110 at the top of the drawers 110 and 110 ′ by sliding and protruding to the drawer 110 and 110 ′. The key module 120 is rotated by a key suitable for the module 120, and a separate control unit 130 is coupled to the inner surface of the drawer body 100.

At this time, a pair of locking pins 131 and 131 ′ are protruding from one end of the control bar 130 so as to interfere with the elevating and descending pins 121 protruding from the inside of the key module 120. In addition, the locking pins 132 and 132 ′ protruding toward the drawers 110 and 110 ′ are formed under the locking pins 131 and 131 ′, and the key module 120 ), when the key module 120 is rotated while the key is inserted, the inner elevating pin 121 rotates together to change the position up and down, and the elevating pin 121 rotates up and down. Accordingly, due to the locking pins 131 and 131 ′ of the enforcement unit 130 that interfere with the lifting and lowering pins 121, the enforcement unit 130 moves up and down together, and the enforcement unit 130 Due to the rise of the lockout pins 132, 132' of the lockout 130 are inserted into the sides of each drawer 110, 110', the simultaneous locking state for the drawers 110, 110' When the control bar 130 is lowered by the rotation of the key, the locked drawers 110 and 110 ′ are simultaneously unlocked.

At this time, the control table 130 is embedded in one side of the inner surface of the drawer body 100 or formed in close contact with the inner surface of the drawer body 100 as in the past, and the drawer is provided with a separate support bracket (not shown in the drawing). While it is not separated from the main body 100, it is coupled so that the movement in the up and down directions is freely performed.

In such a drawer, in the present invention, a separate control mechanism 200 corresponding to the control pins 132 and 132 ′ of the control table 130 is provided on the side of the drawer 110 and 110 ′. Protruding formed, and provided with a separate elevating resistance means 300 in the intermittent zone 130, the intermittent elevating or lowering by mutual interference between the intermittent operation device 200 and the elevating resistance means 300 ( 130) is configured to prevent arbitrary flow.

Here, the intermittent operation tool 200 includes a vertical flow groove 201 in which the intermittent pins 132 and 132 ′ are inserted, and an inclined flow groove formed open upward from the lower end of the vertical flow groove 201 ( 202), and the vertical flow groove 201 by the inclined flow groove 202, consisting of a locking projection 203 on one side, the elevating and descending action of the control bar 130 by the inclined flow groove 202 and the vertical The flow groove 201 and the locking step portion 203 is configured to automatically lock and release the drawer.

That is, the intermittent operation tool 200 has a rectangular block shape having a predetermined thickness, and a vertical flow groove 201 in a vertical direction is formed at a predetermined eccentric position from the center of the intermittent operation tool 200 The inclined flow groove 202 is formed in an open end shape from the lower end of the vertical flow groove 201 to one side, and the inclined flow groove 202 moves the rear direction of the drawer. Is directed.

In addition, due to the inclined flow groove 201 formed on one side of the vertical flow groove 201, between the vertical flow groove 201 and the inclined flow groove 201, corresponding to the lower end of one side of the vertical flow groove 201 The locking step portion 203 is naturally generated, and these vertical flow grooves 201 and inclined flow grooves 202 are intermittent pins 132 and 132 ′ of the aforementioned intermittent table 130 are inserted into these vertical flow grooves. The intermittent pins 132 and 132' are interfered by the 201 and the inclined flow groove 202, and the intermittent bar 130 can move up and down in the up and down directions.

At this time, in the case of the intermittent operation device 200, if the drawers 110 and 110 ′ are assembled and manufactured by wood, the intermittent operation device 200 is separately manufactured and a drawer made of wood as described above. It will be formed by fixing bolts to the side of (110) (110'), and if the drawers 110 and 110' are made by synthetic resin injection, the drawers 110 and 110' It can be manufactured so that the above-mentioned intermittent operation device 200 is integrally protruded on the side, and in a state in which the drawers 110 and 110 ′ are injection-molded in a normal form, the separately manufactured intermittent operation device 200 is bolted. It would be okay to fix it.

Subsequently, the elevating resistance means 300 is for suppressing the free elevating and descending of the chopper 130 that is elevating in the up and down directions by its own weight or vibration or impact, and the aforementioned chopper 130 ) On one side of the locking grooves 133, 133' at regular intervals, and a separate tanjigu 310 on one side of the chopper 130 in which the locking grooves 133, 133' are formed. It is fixedly formed on the inner surface of the drawer body 100, but the tanji pieces 311 and 311' which are inserted into the locking grooves 133 and 133' are protrudingly formed in the tan jigu 310.

At this time, the upper and lower intervals between the locking grooves 133 and 133' in which the intermittent zone 130 is formed are the lower end of the vertical flow groove 201 and the inclined flow groove 202 of the intermittent operation tool 200 It is to be formed equal to the height between the tips, and the bullet point 310 in the process of raising and lowering the enforcement unit 130 from the interference between the control operation tool 200 and the control pins 132, 132' The tanji pieces 311 and 311 ′ of the locking grooves 133 and 133 ′ change their position to the locking grooves 133 and 133 ′ and are elastically held and serve to fix the position of the chopper 130 in an elevated or lowered state.

Accordingly, as shown in FIG. 6 in a state in which the control bar 130 is lowered by the rotation of the elevating pin 121 of the key module 120, that is, the lock for the drawers 110 and 110 ′ is released. When a specific drawer 110, 110' of interest is pulled out and opened, the intermittent pins 132 and 132' of the intermittent table 130 inserted in the intermittent operation tool 200 cause interference and oblique flow As it is guided to the groove 202, the chopper 130 rises, and at the same time, the drawers 110 and 110 ′ of the rest of the drawers 110 and 110 ′ are locked to the chopper 130 and at the same time, any opening is possible. It can be prevented.

That is, as shown in FIG. 7, in a state where all drawers are closed, the cracker 130 will be in a lowered state, and the cracker pins 132 and 132' of the cracker 130 are each drawer 110 ( 110 ′) is located under the vertical flow groove 201 of the intermittent operation tool 200 formed on the side surface.

In addition, the tanji pieces 311 and 311 ′ of the elevating resistance means 300 are in the locking grooves 133 and 133 ′ located on the upper side of the locking grooves 133 and 133 ′ of the enforcement unit 130 You have a locked state.

In such a state, when the user wants to lock all of the drawers 110 and 110 ′, the key is inserted into the key module 120 so that the rotation of the key module 120 and the elevating pin 121 are moved upward. When the elevating pin 121 is rotated to cause interference with the locking pins 131, 131 ′ on the upper side of the enforcement unit 130, the upward action of the enforcement unit 130 occurs, and the enforcement unit 130 ) Due to the rise of each of the intermittent pins 132 and 132' is moved to the upper side of the vertical flow groove 201. Even if the drawers 110 and 110' are pulled in the above state, the intermittent pins Since (132) (132') is constrained in the front and rear directions by the locking projections 203 on the upper inner side of the vertical flow groove 201, the drawers 110 and 11' above cannot be opened. The state comes to pass.

Subsequently, when the intermittent bar 130 is lowered together by the rotation of the key module 120 and the lowering of the elevating pin 121, the intermittent pins 132 and 132' are vertical of the intermittent operation tool 200. It is located under the flow groove 201, and in such a unlocked state, when a specific drawer 110, 110 ′ is pulled and opened as shown in FIG. 8, the intermittent operation tool 200 becomes the drawer 110 ) (110') is moving in the withdrawal direction, and the intermittent pins 132 and 132' located under the vertical flow groove 201 due to the movement of the intermittent operation tool 200 are inclined flow grooves 202 ), and acts as a force to push up the chopper 130 upward.

Therefore, when the target drawers 110 and 110 ′ are completely opened as described above, and the corresponding control operation tool 200 is separated from one side of the control unit 130, the electric power is performed in the elevated state of the control unit 130. Due to the mutual locking force of the lifting and lowering resistance means 300, the intermittent bar 130 is maintained in an elevated state, and the intermittent pins 132 and 132 ′ formed protruding from the intermittent bar 130 are Since it is located on the upper side of the vertical flow groove 201 of each intermittent operation device 200, in the end, an automatic locking state with the intermittent table 130 for the drawer outside the opening as described above is produced.

Accordingly, one desired drawer is opened and the other drawers are simultaneously locked or locked, thereby preventing unnecessary opening.

In addition, when one open drawer is pushed back and closed as described above, the control mechanism 200 is also directed toward the corresponding control pins 132 and 132 ′ by the retraction action of the drawers 110 and 110 ′. As shown in FIG. 9, the control pins 132 and 132 ′ of the control table 130 are retracted, and the control pins 132 and 132 ′ of the control table 130 are continuously moved in the closing direction of the drawers 110 and 110 ′. It is to be guided and inserted into the inclined flow groove 202.

Therefore, by simply pushing and closing the drawers 110 and 110 ′ in the open state, the intermittent pins 132 and 132 ′ of the intermittent table 130 are vertically flowing grooves 201 along the inclined flow groove 202. ), and the interfering action of the control pins 132 and 132' like this serves to lower the cracker 130, which is in an elevated state, and eventually cracks down on all drawers 110 and 110'. The intermittent pins 132 and 132 ′ inserted in the operation tool 200 are positioned under the vertical flow groove 201, and are individually unlocked or unlocked for all drawers 110 and 110 ′. Will come true.

Accordingly, the drawer of the present invention can be used to lock or unlock all of the drawers 110 and 110 ′ using a key as in the past, as well as one drawer desired in the unlocked state of the drawer. In the case of withdrawal and opening, temporary locking or locking of the other drawers other than the withdrawal opening prevents unnecessary opening of drawers, and at the same time, all drawers are opened as if pouring out at one time due to a tilting of the floor, and the drawer is overturned or overturned. This can effectively prevent damage or injuries to users.

Next, in the present invention, as another embodiment of the above-described lifting and descending resistance means 300, as shown in FIG. 10, a magnet body 320, 320' is embedded in the inner surface of the drawer body 100, but the above The magnet body 320, 320 ′ is arranged to face the enforcement unit 130, and the enforcement unit 130 is made of iron so that it can be attached by the attraction of the magnet body 320 and 320 ′. As a result, the chopper 130 is capable of suppressing free elevating and descending due to its own weight, vibration, or impact.

Therefore, due to the magnetic body 320, 320 ′ and the cracker 130 made of iron, the raised cracker 130 or the lowered crackdown 130 can maintain the corresponding moving state as it is, The attractive force of the magnet body 320 and 320 ′ with respect to the enforcement unit 130 will ideally be such that it can be artificially raised and lowered by interference with the enforcement unit 200 or operation of the key module 120. .

Accordingly, in the present invention, the drawer is configured to open a desired drawer in a state in which the lock state of the drawer is released, and at the same time to create a lock or lock state for the drawer outside the opening, and the control unit ( 130) as in the past, as well as the simultaneous locking or unlocking of the drawers 110 and 110 ′, as well as the locking action for the drawers other than the opening as described above, as well as very economical and excellent efficiency. To have.
