Before describing the present invention with reference to the accompanying drawings, it should be noted that the present invention is not described or specifically described with respect to a known configuration that can be easily added by a person skilled in the art, Let the sound be revealed.

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a table-

Specifically, since the upper plate supporting portion supporting the upper plate of the desk and the lower supporting portion supporting the upper plate supporting portion are inclined from the lower supporting portion, the inclination of the upper plate of the desk can be inclined, And more particularly, to a table locking device capable of adjusting the angle of a top plate.

Further, the present invention relates to a table locking device capable of adjusting the angle of the upper plate so that the tilt adjustment can be interrupted when the desk is used, thereby preventing inconvenience in use.

The present invention will be described with reference to Figs. 1 and 2 of the accompanying drawings.

FIG. 1 schematically shows a main configuration of a table locking device capable of adjusting the angle of a top plate according to the present invention, and FIG. 2 schematically shows the configuration of a top plate supporting device of a table locking device capable of adjusting the angle of a top plate according to the present invention.

Referring to Figure 1,

The lower support portion 10 and the upper plate support portion 20 are each composed of two, and in particular, the lower support portions 10 may be configured to be interconnected. It should be noted that this is for the purpose of clarification of the present invention and in fact it may lack connection if the lower support 10 can be erected from the ground and each lower support 10 and upper support 20 may comprise one or two Or more.

The lower support part 10 may include an upper body 11 and a lower body 11 'connected to the lower side of the upper body 11 and supported to the ground. The structure omitted in the drawings may be variously designed as will be apparent to those skilled in the art.

A first protrusion 12 may protrude from one side of the upper body 11 of the lower support 10. The first protrusion 12 may have a groove formed at one end thereof, 12a may be formed of a flexible material such as rubber.

At this time, the wear-and-holding member 12a can prevent the engagement protrusion 21 from being worn when it comes into contact with the engagement protrusion 21 described later.

The second protrusion 13 may protrude from the other side of the upper body 11. The second protrusion 13 may be connected to the variable portion 15 through the connection portion 14. [

The variable portion 15 is connected to the connection portion 14 through a hinge H and is rotatable about the hinge H as an axis. The second projecting portion 13 and the connecting portion 14 may be connected to each other by various coupling methods such as a combination with a screw or a bolt.

In addition, it is preferable that the lower side of the second projecting portion 13 is curved by the connection structure of the connecting portion 14 and the variable portion 15. This is for the purpose of facilitating the rotation of the variable portion 15 through the hinge H.

An upper plate supporting portion 20 is connected to the upper surface of the variable portion 15.

According to an embodiment of the present invention as described above, the upper surface of the variable portion 15 and the upper plate supporting portion 20 may be connected to each other by attachment or screw / bolt connection.

The upper plate support portion 20 may be formed in a rod shape and may have a groove portion 20 'extending along the longitudinal direction as shown in FIG. 2 on a surface contacting the upper surface of the variable portion 15.

The upper plate supporting portion 20 can be closed with a cap 20 '' which is opened at both ends and formed so as to correspond to the sectional shape of the upper plate supporting portion 20. Through holes are formed in the plug 20 ' (30) is infiltrated into the inside.

The groove 20 'on the one end side into which the wire 30 is infiltrated may include a spring as shown by the dotted line in FIG. 2. The spring has one end contacting the inner surface of the stopper 20' ', So as to contact the engaging protrusion 21 inserted in the groove 20 '.

The latching protrusion 21 is configured such that a part thereof is inserted into the groove 20 'and the remaining part is exposed from the groove 20'. At this time, the exposed part is formed in a ring shape.

The wire 30 penetrates into the plug 20 " as described above and penetrates the spring and is connected to one end of the locking protrusion 21. [

The other end of the wire 30 may be exposed to the outside of the upper plate supporting portion 20 and may be connected to the operation body 40.

One end of the wire 30 connected to the operation body 40 is connected to an operation unit 41 operated inside the operation body 40. When the operation unit 41 is operated in the pulling direction, Thereby pulling the stopper 21 in the spring direction.

On the other hand, when the pulling of the operating portion 41 is released, the pulling of the wire 30 is released, and the latching protrusion 21 can be returned to the original position by the elastic force of the spring.

The wire 30 may be received in the operation body 40 and connected to the operation unit 41 or may be connected to the operation unit 41 through the operation body 40. [

The wire 30 is configured to cover the surface of the metal wire with the cover cover, and the cover cover can be configured to enclose only the area of the wire exposed to the outside.

Referring again to FIG. 1,

When the locking projection 21 is pulled in the spring direction by pulling the operating portion 41 while the locking projection 21 is engaged with the waved supporting member 12a of the first projection 12 during use of the desk, (21) is not caught by the hair-holding member (12a).

In this state, when the upper plate or the upper plate supporting portion 20 of the desk is lifted, the upper plate and / or the upper plate supporting portion 20 of the desk can be inclined.

Then, when the upper plate of the desk is returned to its original state, the locking protrusion 21 is bent in the form of a hook, so that the locking protrusion 21 hits the heating element 12a and is caught again. At this time, since the wear-and-holding member 12a is made of a flexible material, the stopper 21 may not be worn even if it is impacted.

However, the present invention proposes a structure according to Fig. 3 as a method for completely preventing the abrasion of the engaging protrusion 21.

FIG. 3 is a schematic view showing another embodiment of a top plate supporting part of a table locking device capable of adjusting the angle of a top plate according to the present invention.

3, an intermittent groove 22 is formed on an upper side of both side walls of the groove 20 'of the upper plate supporting portion 20.

The jutting protrusion 23 is inserted into the intermittent groove 22 and the jutting protrusion 23 is formed so that the upper side thereof is curved and the intermittent projection 24 is connected to one side.

At this time, the intermittent projection 24 may be exposed to the outside of the groove 20 'through a groove (not shown) formed on the side surface of the groove 20'.

The elastic member 25 has one end contacting the one wall surface of the intermittent groove 22 and the other end contacting the one surface of the intermittent projection 24. [ .

In this case, the following constitution of the above-mentioned intermittent groove portion 22 is shown as being distant from the engagement protrusion 21, but this is only for the sake of easy understanding of the present invention, Is formed in the vicinity of its original position when it is not pulled in the direction of the plug 20 ". The reason for this can be sufficiently predicted by the function of the constitution below the intermittent groove section 22 described later.

In the above description, it is described that the top plate of the desk is placed at its original position so that the latching protrusion 21 is caught by the bottom plate 12a. The material of the bottom plate 12a prevents the latching protrusion 21 from being worn However,

It is practically impossible to prevent wear due to continuous use.

Therefore, according to the present invention, when the upper plate of the desk is lowered, it is prevented that at least the latching protuberance 21 and the wear-and-holding member 12a are brought into contact with the upper plate of the desk before the abrasion due to the impact is prevented.

When the operation unit 41 is pulled and the locking projection 21 is pulled, the interlocking projection 24, which has not protruded into the groove 20 'by the locking projection 21, protrudes into the groove 20' . This is due to the elastic force of the elastic member 25.

Therefore, the protruding interlocking protrusion 24 functions to intermittently prevent the locking protrusion 21 from advancing due to the elastic force of the spring even when the operating portion 41 is released, which is illustrated in Fig. 3 , It is preferable that two interlocking trenches 22 to 25 are formed on both sides of the stopper 21 as a reference.

The upper plate support portion 20 is completely lowered and the curved surface of the pushing projection 23 of the first projecting portion 12 is pushed back and the interlocking projection 24 is also retracted, The collision protector 21 returns to its original position due to the elastic force of the spring, so that the collision between the locking protrusion 21 and the wearer rest 12a can be minimized (Fig. 3 (a) And (b)). Therefore, the impact transmitted to the locking protrusion 21 is reduced, thereby blocking the original cause of the wear.

This is possible because the curved surface of the jaw projection 23 is bent in the direction of the groove 20 '.

For this purpose, it is preferable that the width of the upper plate support portion 20 is configured not to be too wide than the width of the first projecting portion 12.

On the other hand, by allowing the upper plate adjusting portion 20 whose inclination is adjusted to slide on the lower supporting portion 10, the upper plate of the inclined desk can be moved downward to further reduce the storage volume.

This is illustrated in Figure 4 of the accompanying drawings.

FIG. 4 is a schematic view showing a combined structure of a top plate supporting part and a bottom supporting part of a table locking device capable of adjusting the angle of a top plate according to the present invention.

4 of the accompanying drawings,

Two variable groove portions 15 'partially formed in the longitudinal direction are formed on one side of the variable portion 15.

The roller 17 includes a shaft 16 protruding upward and a roller 17 rotating with respect to the shaft 16 at one side of the upper surface of the variable portion 15, Two roller grooves 17 'formed corresponding to the grooves 15' can be formed.

In addition, at one side of the connection part 14, two fixing rods 18 to be inserted into the variable groove 15 'and the roller groove 17' may be formed.

The variable section 15 'and the roller groove 17' are configured to open at one end so that when the variable section 15 rotates about the hinge H, And can be separated from the groove 15 'and the roller groove 17'.

The roller 17 has an outer diameter corresponding to the width of the groove 20 'of the upper plate supporting portion 20 and is fitted in the groove 20' to be rotated along the side surface of the groove 20 '. Thus, the groove 20 'serves as a rail, so that the upper plate supporting portion 20 can be slid upward or downward with respect to the lower supporting portion 10.

However, since the top plate can not be slidably moved by the rotation of the roller 17 in a state where the desk is used or the top plate of the desk is not tilted, the fixing rod 18 prevents the roller 17 from rotating, So that the rollers 17 can not be rotated unless the top plate of the desk is tilted through the rollers 15.

Accordingly, when the top plate of the desk is not tilted, it is used as a general desk, and when the desk is tilted, the height of the desk can be reduced by moving the slide.

It is apparent that the present invention is not limited to the configuration of the drawings, as described above with reference to the drawings, only the main points of the present invention are described, and various designs can be made within the technical scope thereof.
