Referring to FIGS. 1 to 10, an anti-furniture device 100 according to an embodiment of the present invention includes a housing 110, a support member 120, an operation unit 200, and a supporter 130.

In particular, a plurality of furniture preventive apparatuses 100 according to the present invention are provided on the bottom surface of the furniture shelf 10, and two furniture shelves 10 are disposed side by side on the bottom surface of the furniture shelf 10 for convenience.

Accordingly, the furniture anti-falling device 100 according to the present invention also serves as a bridge of the furniture shelf 10.

The housing 110 is connected to the furniture shelf 10. In detail, the housings 110 are provided in a pair arranged side by side on the lower side of the furniture shelf 10, and are disposed such that their axial directions are parallel to the front-rear direction of the furniture shelf 10. In addition, each of the housings 110 is connected to the lower side of the furniture shelf 10.

At this time, each of the housings 110 is to be detachably coupled to the lower side of the furniture rack 10 by the bracket 112.

Of course, the bracket 112 can be deformed into various shapes and is fastened to the lower side of the furniture rack 10 by the fastening member 113 while accommodating the housing 110. Here, the fastening member 113 is a bolt or a screw.

The housing 110 is applicable in various shapes and various materials.

Also, the support member 120 is provided in each of the housings 110 so as to be axially movable in and out. Thereby, the support member 120 can be pulled out in the axial direction in the housing 110.

Of course, the support member 120 may be provided so as to be movable in the axial direction while being arranged in parallel with the housing 110 from the outside of the housing 110. In particular, the support member 120 is provided so as to be able to move in and out of one side of the housing 110, that is, the front side.

Further, the support member 120 can be applied in various shapes and various materials.

In addition, the support member 120 is drawn out from the housing 110 when the furniture shelf 10 is tilted toward the setting direction, particularly forward. As a result, the furniture shelf 10 can no longer fall forward.

The operation unit 200 has a function of guiding the support member 120 in its initial state inserted into the housing 110 to be forcedly drawn out from the housing 110 by being interlocked with the furniture member 10 tilted forward do.

In other words, when the furniture shelf 10 is tilted forward, the supporting member 120 is pulled out of the housing 110 in front of the falling of the furniture shelf 10, Thereby supporting the furniture shelf 10 to be erected. Thus, the furniture shelf 10 no longer tilts or falls.

The supporter 130 is provided on the support member 120 and has a fixed foot 132 which is in contact with the floor.

The supporter 130 rotates with respect to the support member 120 when the support member 120 is pulled out from the housing 110 and tilted so that the supporter 130 stably contacts the fixed foot 132 to the floor .

That is, in a state in which the support member 120 is drawn out from the housing 110, the support member 120 is not shaken as the stationary foot 132 stably contacts the ground. Thus, the furniture shelf 10 can not fall more stably.

Specifically, the supporter 130 is rotatably provided to the connector 136, and the connector 136 is detachably coupled to one side of the support member 120. [

In particular, the supporter 130 is provided with a fixed foot 132 on the lower side and is vertically rotatable by the pivot pin 134.

Thus, when the furniture shelf 10, the housing 110 and the supporting member 120 are tilted so that the rear side of the furniture shelf 10 can be heard, the supporting member 120 is pulled out of the housing 110, 130 are pivoted upward relative to the support member 120 with respect to the pivot pin 134. Thus, the fixed foot 132 of the supporter 130 is stably supported on the floor surface.

At this time, even when the support member 120 is inserted into the housing 110 as much as possible, the support member 120 contacts the bottom of the elastic roll member 220 And is forcefully pulled out of the housing 110 by an elastic restoring force.

The connector 136 is constrained to the support member 120 by the constraining pin 138 while the support member 120 is hinged. At this time, the constraining pin 138 can be variously applied.

Of course, the supporter 130 may be directly hinged to the support member 120, but it is rotatably connected to the separate connector 136 so as to be replaceable while reducing maintenance cost. Of course, the connector 136 can be deformed into various shapes.

Particularly, when the support member 120 is inclined so that one side of the support member 120 to which the supporter 130 is connected is downwardly inclined, the supporter 130 is rotated in the upward direction with respect to the connector 136, (136).

In addition, the fixed feet 132 may be coupled to the supporter 130 so as to be adjustable in height.

The operating portion 200 includes a mounting member 210, an elastic roll member 220, and a locking portion 300.

The mounting member 210 is fixed to the inside of the other side of the supporting member 120, particularly, the supporting member 120. Thus, the mounting member 210 can be moved in the axial direction of the supporting member 120 together with the supporting member 120. [ Of course, the mounting member 210 can be applied in various shapes and various materials. In addition, the mounting member 210 is firmly fixed to the supporting member 120 so as to be detachable by the bolting member 212.

In addition, the elastic roll member 220 is rotatably mounted to the mounting member 210 with respect to the center shaft 222. The center shaft 222 may be mounted on the mounting member 210 on both sides after the shaft is inserted into the elastic roller member 220 and may be provided on opposite inner sides of the mounting member 210 to rotate the elastic roller member 220 It may be possible to mount it.

In addition, one side of the elastic roll member 220 to be unwound is fixedly connected to the housing 110.

Specifically, the support member 120 forms an opening 122 to expose the elastic roll member 220 to the housing 110 side, and the housing 110 supports the elastic roll member 220 through the opening 122, And a hook 114 may be provided for fixing the position by hanging one side of the hook 114.

Accordingly, the elastic roll member 220 may be connected to one side of the elastic member 220 so that the elastic member 220 can be firmly fixed to the hook 114. Of course, the hooks 114 can be formed in various ways.

Of course, the elastic roll member 220 can be variously applied.

As the support member 120 is elastically expanded when the shaft is inserted into the housing 110, an elastic restoring force acts on the elastic roll member 220 as a roll type. As a result, a force to pull the elastic member 220 in an initial state, which is inserted into the housing 110 as much as possible, is applied to the elastic member 220 due to a force to wind the elastic member 220 in an initial state.

Accordingly, the locking part 300 serves to restrain the support member 120 from being initially inside the housing 110. [

In addition, the locking part 300 serves to release the restraint of the support member 120 when the furniture shelf 10 tilts forward. Accordingly, the support member 120 is forcibly drawn out to the outside of the housing 110 by being allowed to move in the axial direction by the elastic restoring force of the elastic roll member 220.

In particular, the mounting member 210 or the supporting member 120 includes a guide pin 216, and the housing 110 includes a guide hole 216, which receives the guide pin 216 to guide the linear movement of the supporting member 120, (116) can be formed.

The guide member 116 can guide the guide pin 216 in a straight direction so that the support member 120 can be stably guided and conveyed in a straight line and the conveyance distance is limited, Separation can be prevented.

For convenience, the guide pin 216 is shown protruding from the support member 120. The guide hole portion 116 may have a hole shape, but may be formed in a groove shape.

The locking part 300 includes a fixing block 310, a locking block 320, a locking protrusion 330, a locking hole 340 and a locking protrusion 350.

The fixing block 310 is fixedly mounted inside the housing 110. In particular, the fixing block 310 can be fixedly mounted inside the setting portion of the housing 110 which is opened to the floor when the furniture shelf 10 is inclined.

Specifically, the fixing block 310 is installed inside the other side opposite to one side of the housing 110 that receives the supporter 130 in an initial state.

Of course, the fixed block 310 can be applied in various shapes and various materials.

The locking block 320 is seated inside the fixing block 310. At this time, the fixing block 310 is formed to be opened in the direction toward the inner upper side of the housing 110 in the initial state.

In addition, the locking block 320 protrudes from the locking protrusion 330 on one side. The shape of the stopper portion 330 can be variously applied.

The latching hole portion 340 is formed on the other side of the support member 120 and accommodates the stopper portion 330 in the initial state. Thus, even when the elastic roll member 220 is subjected to an elastic restoring force, the support member 120 is prevented from moving forward in the axial direction. Of course, the latching hole portion 340 is applicable to a hole or a groove shape.

When the furniture shelf 10 and the housing 110 are inclined upwardly, the locking roof 350 is inclined upwardly from the one side of the housing 110 to the other side of the housing 110, And the locking block 320 to be disposed is forcibly pushed to the bottom side of the fixing block 310 to relieve the locking protrusion 330 from the locking hole 340.

In detail, the locking assembly portion 350 includes a push block 352 and a push spring member 354.

The push block 352 is disposed on the opposite side of the fixing block 310 of the retaining block 320. That is, the push block 352 is placed on the upper side of the latch block 320. Of course, the push block 352 can be applied in various shapes and various materials. The push block 352 has an operation foot 355 protruding downward from the housing 110 through the housing 110. The operation foot 355 may be screwed to the push block 352 so as to be adjustable in height.

Therefore, the supporter 130 disposed at one side of the housing 110 has the fixed feet 132, and the push block 352 disposed at the other side has the actuating feet 355. Accordingly, the anti-fall device 100 including the fixed feet 132 and the operating feet 355 may serve as a bridge of the furniture shelf 10.

One side of the push spring member 354 is resiliently supported on the inner upper surface of the housing 110 and the other side is resiliently supported on the bottom surface of the push block 352. Since the weight of the housing 110 is heavier than the weight of the push block 352, the push spring 354 can be resiliently supported by the housing 110 so that the push block 352 is elastically . Thus, the push block 352 pushes the retaining block 320 toward the bottom surface side of the fixing block 310.

The push spring member 354 is disposed between the inner upper surface of the housing 110 and the push block 352 to be in a compressed state. That is, when the operation foot 355 touches the floor, when the pressing force of the furniture field 10, the housing 110 and the support member 120 by their own weight acts, the operation foot 355 is moved to the position- 110, the push spring member 354 is compressed as the push block 352 is subjected to a force to be lifted.

When the housing 110 is inclined, the push block 352 is pushed toward the bottom surface of the fixing block 310 together with the latch block 320 by the resilient restoring force of the push spring member 354.

Thus, the locking projection 330 of the locking block 320 is disengaged from the locking hole 340. Accordingly, the support member 120 is drawn (advanced) to one side of the housing 110 by the elastic restoring force of the elastic roll member 220.

Here, the push spring member 354 can be variously applied, such as a coil spring.

Particularly, the latching block 320 is rotatably connected to the fixing block 310 at an opposite side edge of one side edge of the latching block 330. That is, the other side of the latching block 320 is connected to the fixing block 310 by the hinge pin 322, so that the latching block 320 can be rotated along the arc locus based on the hinge pin 322.

Then, the retaining block 320 is elastically supported on the bottom of the fixing block 310 by the support spring member 324. Particularly, a lower side of the retaining block 320, which forms the locking projection 330, is elastically supported by the support spring member 324 with respect to the fixing block 310.

Accordingly, the retaining block 320 is prevented from being downwardly arbitrarily selected, and the support spring member 324 is compressed downward by the pressing force of the push block 352. As a result, the engagement protrusion 330 is prevented from being arbitrarily detached from the engagement hole 340.

Here, the support spring member 324 can be variously applied, such as a coil spring.

At this time, since the push block 352 must press the retaining block 320 when the push spring member 354 pushes the push block 352 with an elastic restoring force, the elastic modulus K1 of the push spring member 354 is not supported by the support Is greater than the elastic modulus K2 of the spring member 324. (K1 > K2)

The push block 352 is inserted into the retaining block 320 and the retaining block 310 to increase the area of the connecting portion of the operated foot 355 to increase the durability of the actuating foot 355, .

In order to prevent the push block 352 from completely disengaging from the lower side of the fixed block 310, a push tab 357 is formed on the circumferential surface. And the push jaw 357 is brought into contact with the upper surface of the push block 352. [ More specifically, since the push block 352 compresses and pushes the push spring member 354 in an initial state in which the push spring member 354 is compressed, the push jaw portion 357 is engaged with the upper surface of the retaining block 320, do.

Thereafter, when the push spring member 354 is resiliently restored, the push block 352 is lowered until the push-in step portion 357 is engaged with the retaining block 320. That is, the pushing jaw 357 pushes the retaining block 320 toward the bottom surface side of the fixing block 310.

Of course, the push jaw 357 can be deformed into various shapes.

On the other hand, the supporter 130 is bound or bound to the housing 110 by the binding portion 140, thereby preventing the supporter 130 from being arbitrarily drawn out from the housing 110.

Here, the binding portion 140 includes a binding lever 142, a binding piece 144, and a binding port 146.

The binding lever 142 is rotatably inserted into the supporter 130. The binding piece 144 is provided on the circumferential surface of the binding lever 142 located inside the supporter 130. Thus, the binding piece 144 is rotatable together with the binding lever 142. Of course, the binding piece 144 can be deformed into various shapes.

The binding port 146 is formed in the housing 110 so as to bind or unbond the binding piece 144 in accordance with the amount of rotation of the binding piece 144. [ Here, the binding port 146 may be formed in a hole or groove shape.

The binding piece 144 is rotated together with the rotation of the binding lever 142 and the binding piece 144 is accommodated in the binding hole 146 so that the supporter 130 is constrained to the housing 110. On the other hand, when the binding piece 144 is separated from the binding hole 146, the supporter 130 is released from the housing 110.

Thereafter, when the furniture shelf 10 is tilted forward, the support member 120 can be pulled out to the outside of the housing 110 due to the operation of the locking portion 300. Thus, the furniture shelf 10 can not be inclined or fall over a certain angle.

Particularly, initially, even if the fixed foot 132 is in contact with the floor, the elastic roll member 220 is resiliently restored and the force for pulling the support member 130 to one side of the housing 110 is transmitted to the fixed foot 132 The supporting member 120 becomes able to be drawn out of the housing 110. As shown in Fig.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. I will understand. Accordingly, the true scope of the present invention should be determined by the following claims.
