And throughout this specification, like reference numerals refer to like elements throughout.

The present invention is disclosed with respect to a folding desk table.

Particularly, the present invention is an improvement of a related structure of an existing support (reinforcement bar) which is integrally provided with a table leg so as to withstand a vertical load, and maximizes the convenience in storage, storage and transportation by easy de- In addition to the fact that the connector is differentiated from the existing one, the additional fastening of the connector to the legs and the legs of the table leads to a very good assembling performance. In addition, it prevents the lateral flow and contributes to dispersion and offsetting of the load stress. It is noted that the present invention relates to a folding-type desk table 100 constructed as a holding assembly type.

As shown in FIGS. 1 to 8, the folding type folding table 100 according to the present invention is characterized in that the supporting table and the supporting table are separated from each other for convenience of handling when carrying, storing, And it is also a technical concept that it is possible to induce a firm fastening of the support table and the support table due to the connector exhibiting the same level of cohesion as the conventional welding.

To this end, the upper supporting column type folding type desk table 100 includes a supporting frame 10 having mobility and disposed at positions corresponding to each other, a top plate 20 disposed transversely through the supporting frame and allowed to move in one direction A support (30) interposed in the space between the support frames and supporting the upright of the both support frames while maintaining a vertical load; and a supporting frame (30) having mobility and cross- And an auxiliary frame (99) for constructing a downward slope.

It should be noted that the upper strut 30 is separated from the two side support frames 10 so that it is determined whether the lower strut 30 is engaged with each support frame via two sets of connectors 50, And the outer periphery of the pillar is surrounded at the both ends of the pillar to be restrained in position through the side surface of the pillar to thereby induce mutual binding between the pillar 30 and the supporting frame.

As shown in the figure, the upper support frame 10 is bent in a predetermined shape so as to come into contact with the struts 30, and a lead-in hole 11, which determines the horizontal position of the support, is perforated. After the support frame is horizontally aligned through the support frame, the load imposed by the top plate 20 or other external factors is resisted by the structure integrated with the support.

The upper struts 30 are interposed between the support frames 10 so as to exert a more rigid supporting force of the support frame with respect to the vertical load. The upper struts 30 exhibit desired functions as both ends of the struts are connected to the support frame.

In the present invention, the support (30) and the support frame (10) are provided in a separated form. It is preferable to drill a through hole (31) penetrating both ends of the support column

In particular, the strut 30 of the present invention is fastened through a connector 50 of a predetermined shape, not directly fastened to the support frame, whereby the upper connector 50 has a flexure corresponding to the flexion of the support frame To provide a more tightly coupled force.

The upper connector 50 includes a fastening means 40 through which a coupling force with a strut is induced by being traversed in a transverse manner through a strut 30 and a fastening means 60 ).

The upper fastening means 40 is pierced on the side of the support for mutual engagement of the support and the connector, and the upper binding means 60 is formed on the connector base in the lengthwise direction of the support Respectively.

This configuration is for the purpose of inducing the same or a higher level of bonding force as compared with the conventional case where the support 30 and the support frame 10 are integrally provided.

The folding table is provided in the form of an expanded form of the top plate in order to satisfy the various demands of the consumers and to increase the utilization value thereof. However, in a folding table other than a fixed table, such a size expansion may cause a vertical load exceeding the allowable limit on the table leg (support frame), so that a reinforcing bar (support) Of the user.

That is, the struts are arranged transversely to the space between the table legs while extending to the length corresponding to the upper plate. In order to maximize the coupling force, the table legs and the struts are integrated by welding or the like. Problems cause a great inconvenience in storing, storing, transporting, or the like. As a result, due to the unified structure of such a holding structure, the folding table is only reduced in local volume, and the size thereof can not be reduced to a satisfactory level, resulting in inconvenience and difficulty in storing, have.

However, it is an object of the present invention to provide a support structure for a support frame, which is capable of supporting a sufficient supporting force as described above. It is desirable to provide a predetermined connector that can be maximized.

The upper connector 50 is provided in a cylindrical shape and is cut at right angles to each other on the basis of a point which is ½ to ⅓ of the entire diameter and a point of ½ to ⅓ of the entire upper and lower length, It is preferable to divide them.

As shown in Fig. 4, the connector 50 of the present invention is divided into a cylindrical main bracket 70 and a bracket unit 80 having a part of the main bracket cut into a shape, and the main bracket 70 and the bracket unit 80 The structure is intended to intervene between the support and the support frame.

The reason for not dividing the main bracket 70 and the bracket unit 80 into a 1: 1 size is to improve the coupling force and the mutual assembling performance over a certain level, and the coupling holes 75 And the fitting protrusions 83 can disperse or offset the shear stress with respect to the vertical load.

The upper connector 50 is constituted by a combination of the main bracket 70 and the bracket unit 80 and the upper main bracket 70 is provided in the same shape as the curvature held by the side surface of the support frame 10 A binding hole (72) penetrating the support surface in the longitudinal direction from the support surface and coinciding with the inlet hole (11) formed on the support frame to allow the binding means (60) to enter, A fastening hole 73 formed in the direction orthogonal to the hole and threadedly engaged with the fastening means 40 which penetrates through the through hole 31 formed in the strut, a cut surface 74 formed so as to be in surface contact with the bracket unit, And a coupling hole 75 formed in a T-shaped incision for restricting the position of the bracket unit.

The upper bracket unit 80 includes a body 81 provided in a shape corresponding to the cut surface 74 and a body 81 formed at a corresponding position of the fastening hole 73 on the body to allow the fastening means 40 to enter. And a fitting protrusion 83 formed in a shape corresponding to the fitting hole 75 and adapted to be fitted to the fitting hole 83.

The upper support surface 71 is formed to have the same bending shape as that of the support frame 10 for firmly restraining the connector 50 and the support frame 10 and the upper binding hole 72 is formed in the inlet hole 11 of the support frame So that the binding means 60 can be interposed by aligning positions on the horizontal line. The binding holes 72 should be recessed into the inner space of the support surface 71 within a range that does not interfere with the fastening holes 73. When the fastening holes are bored in a direction perpendicular to the fastening holes, And the fastening means are fastened in directions intersecting with each other so that the rigid coupling force between the support post and the support frame via the connector 50 can be maintained.

The upper fastening hole 73 protrudes inward from the inner surface of the main bracket 70 as shown in the figure and is formed inside the threaded protruding space for screwing with the fastening means 40.

The upper cut surface 74 overlaps the outer circumferential surface of the bracket unit 80 and forms a single cylindrical shape and functions as a means for guiding the interposition of the fitting projections 83 to the engagement holes 75 due to the engagement with the bracket unit .

The upper coupling hole 75 is a main part of the present invention, and due to the structural characteristics of such a shape, the vertical load can be more firmly supported and can be stably supported against stress that can be locally induced. The related description will be described in detail later.

The fastening hole 82 of the upper bracket unit 80 is a component corresponding to the fastening hole 73 of the main bracket so that the fastening means 40 can be introduced and the fastening means can be accurately guided to the fastening hole . For this purpose, the upper fastening hole 82 may be formed to extend from the inner surface of the body 81, and the range of extension should be set within a range that does not interfere with the fastening hole.

The upholstery hole 75 and the fitting protrusion 83 which are featured in the present invention are formed in the direction orthogonal to the struts 30 and are connected to each other so that a supporting force against the vertical load transmitted from the top plate 20 is generated Preventing flow in the lateral direction and dispersing or canceling the shearing stress.

This is illustrated in detail in FIGS. 5 to 7. The direction of the arrows in the respective drawings indicates the stress to the vertical load, and the load stress maximized in a certain region due to the related structure of the engaging hole 75 and the fit- It will cope effectively.

In other words, by providing the coupling holes 75 and the fitting projections 83 in the vertical direction orthogonal to the struts or the upper plate 20, which is not the same horizontal direction as the struts 30, And the engagement state of the connector 50 is more firmly maintained due to the inclined surfaces of the coupling hole and the fitting projection portion, which acts as a supporting force for preventing the support frame 10 from flowing.

To this end, the upper coupling hole 75 and the fitting projection 83 extend from the cut surface 74 and the body 81 in one direction, respectively, and the first and second extension surfaces 91 and 92 And third and fourth extending surfaces (93, 94) extending in the orthogonal direction on the first and second extending surfaces, and extending in the same direction as the first and second extending surfaces on the third and fourth extending surfaces And a seventh extending surface (97) extending in the same direction as the third and fourth extending surfaces in the fifth and sixth extending surfaces, ;

As shown in FIG. 7, the first, second, fifth, and sixth extending surfaces are each formed to have a constant inclined surface in order to more effectively cope with local stress to the vertical load to induce a strong supporting force.

For example, if the 1st, 2nd, 5th, and 6th extension planes are constructed in a planar shape, the same level of stress acts on the corresponding surfaces, which can not be relieved from the stress of continuous stress even though it is a relatively weak space. However, if the first, second, fifth, and sixth extended surfaces are constructed as inclined surfaces as in the present invention, a section where the first inclined surface and the third inclined surface, which are relatively weak spaces, overlap each other, Even if a local stress is imposed on a section where the fourth slant plane overlaps, a section where the third slant plane and the fifth slant plane overlap each other, and a section where the fourth slant plane and the sixth slant plane overlap each other, Stress and stress can be applied, and it can be supported relatively firmly.

The upper engaging hole 75 and the lower engaging protrusion 83 are sloped in the direction of the support surface 71 so as to be slidably engaged with each other. At this time, the upper engaging means 40 is engaged with the engaging hole and the fitting protrusion So that the mutual binding force between the main bracket 70 and the bracket unit 80 on the support 30 can be maximized.

8 shows the structure of the connector 50 according to another embodiment in detail. According to FIG. 8, when the bracket unit 80 is inserted into the main bracket 70, the cross- And the fastening means 40 is made to intersect at an opposite inclination, so that the assembling property and fastening property of the connector can be further strengthened due to the structural characteristic of being cross-coupled with each other.

According to the folding type foldable table 100 of the present invention constructed as above, unlike the conventional folding type folding table table 100, it is possible to carry out the attachment / detachment of the pillars 30 from the support frame 10, And the effect of ensuring the safety is achieved. In addition, in the present invention, the connector 50 differentiated so as to have a bonding force of the same level as the welding induces mutual coupling between the support and the support frame, thereby maximizing the binding force and maximizing the binding force. The advantage is also expected.

Particularly, the present invention adopts a configuration in which the main bracket 70 and the bracket unit 80 are divided in providing the connector 50, and mutual engagement of the main bracket and the bracket unit is achieved by the fastening means 40 and the binding means 60, The coupling force is maximized by inducing a more reliable fastening based on such a connector, so that it is more effective and moreover, the support force against the vertical load transmitted from the upper plate 20 According to the induced structural characteristics, it is effective to prevent the flow in the lateral direction and actively achieve dispersion or offsetting of shear stress.
