Description

Furniture frame having improved assemblability and durability

The present invention relates to a frame for furniture, and more particularly, to have excellent strength and durability, and contribute to the improvement of productivity and the reduction of manufacturing cost through the simplification of the assembly and coupling structure, and the ease of assembly and disassembly in the field The present invention relates to a furniture frame having improved assembly and durability, which provides convenience of work such as installation and transportation of products.

In general, furniture, such as a bed, table, bookshelf, and the like has a furniture frame including a plurality of vertical frames arranged in a vertical direction, and a plurality of horizontal frames arranged horizontally to connect the vertical frames to each other.

In a frame used for furniture such as a bed or a table, the vertical frame and the horizontal frame are fixed to each other by welding, so that if a single frame structure is required, a lot of time and effort is required for welding work, thereby increasing worker fatigue and It caused a decrease in productivity. In addition, in the case of the furniture frame of the welding method, since it is difficult to disassemble, taking up a large volume during transportation, there was a problem that the cost and inconvenience required for transportation greatly increases.

In order to solve the problem of the frame used in furniture such as a bed or table, a product for assembling a vertical frame and a horizontal frame with a bracket has been developed and used. As a related art, Korean Patent No. 10 The bed frame structure of -1322621 has been presented. It comprises at least four vertical frames erected perpendicular to the floor; A horizontal frame having an edge equal to the number of the vertical frames when combined with each other; And a support bracket portion fixed to each vertical frame, wherein each corner of the horizontal frame is coupled between the vertical frame and the support bracket portion, and the horizontal frame is adjacent to or spaced apart from the support bracket portion. The inner surface is pressed or depressurized by the fixing member which is movable to the fixed frame or fixed to the vertical frame. The support bracket part includes a horizontal plate having a fixing part fixed to the vertical frame on one side, and the vertical frame. And a vertical support bent upwardly perpendicular to the inner end of the horizontal plate, wherein the fixing member is movable relative to the vertical frame by a coupling rod screwed to the vertical support.

However, such a conventional technology causes the horizontal plate to bear most of the load, causing problems of durability deterioration due to deflection of the horizontal plate, and by supporting the frame with only the block-shaped fixing member, such as torsion applied to the frame. There is a limit to endure the external force of the, which has a problem acting as a limit to increase the safety of the frame.

In addition, as a technology related to a table corresponding to another conventional technology, Korean Patent Application Publication No. 10-2018-0089831 discloses a "table frame", which includes a plurality of vertical frames; A plurality of horizontal frames provided on an upper portion of the vertical frame; A connection bracket coupled to the vertical frame; And a horizontal connection part coupled to the connection bracket and connecting the adjacent horizontal frame, wherein the connection bracket includes a first fitting part fitted to the vertical frame; And a connecting protrusion extending to the opposite side of the first fitting portion and connected to the horizontal connecting portion. The connecting projection and the horizontal connecting portion are mutually coupled by a locking portion; The locking portion locking ribs formed on the circumferential surface of the connecting projection; And a locking hole into which the connecting protrusion is inserted and which is coupled to the locking rib by the rotation of the connecting protrusion.

However, this conventional technique has a problem in that due to the coupling structure between the frames connected by a simple fitting coupling, inevitably deteriorate durability, causing inconvenience due to the inability to ensure stable separation during disassembly. .

In order to solve the above problems of the prior art, the present invention is coupled by the locking and bolting structure between the vertical frame, the horizontal frame and the connection brackets, so as to stably support the load between each other and to have excellent strength and durability , Contributing to the improvement of productivity and the reduction of manufacturing cost through the simplification of assembly and assembly structure, and the purpose of providing convenience of operations such as installation and transportation of products on site due to ease of assembly and disassembly.
