The present invention relates to a bracket used to interconnect an upper panel and a pillar member of furniture, which are assembled in directions perpendicular to each other, ready-to-assemble furniture using the brackets, and an assembly method of the furniture, and more particularly, a furniture assembly bracket capable of coupling an upper panel to a pillar member in a fitting manner without additionally using coupling means, allowing users to easily disassemble or re-assemble the pillar member as necessary, and increasing furniture exterior quality, ready-to-assemble furniture using the brackets, and an assembly method of the furniture.
In general, corners of a desk, table, wardrobe, or shelf include parts where ends of three pillars, i.e., a horizontal pillar and two vertical pillars, which form a right angle therebetween.
A method of coupling the three pillars to each other includes a method using connection pins such as nails, a method of providing and combining coupling projections and recesses at coupling parts, a welding method for metallic pillars, a method using brackets, etc. Compared to other methods, a corner assembly method using brackets and coupling screws allows easy assembly and disassembly between members and thus is broadly used these days. That is, an L-shaped bracket is attached to a corner of two members contacting each other at a right angle, and then a coupling screw is fastened into the bracket, thereby coupling the bracket to the corner or a pillar member at the corner.
For example, as illustrated in
However, since a pillar member is coupled to vertical support members by providing a bracket therebetween, the above-described conventional furniture assembly structure does not enable easy assembly and disassembly of furniture and may not be applied to do it yourself (DIY) products which are assembled or disassembled by users.
Furthermore, in the conventional furniture assembly structure, the bracket configured as plate-shaped metal may be deformed and the pillar member may not be firmly coupled to the bracket using only the coupling means, thereby reducing stability of furniture.

The outer member 20 may further include a plurality of positioning projections 21″ protruding from ends of the fixing plates 21 and inserted into the vertical support members 52 in order to mount the outer member 20 on the support member 52 at an accurate location.
In this case, preferably, the positioning projections 21″ have sharp ends in order to easily determine the locations of holes, into which the positioning projections 21″ are to be inserted, when the fixing plates 21 are attached to the vertical support members 52. In other words, hole locations may be marked by pressing the positioning projections 21″ on the vertical support members 52 and holes may be created using a boring tool such as a drill.
Preferably, fitting plates 24 are provided at parts where the fixing plates 21 and the connection plates 23 of the outer member 20 are connected to each other, so as to insert the fixing plates 11 of the inner member 10 thereinto, and side ridges 11b other than top ridges 11a of the fixing plates 11 of the inner member 10 have a small thickness so as to be inserted into the fitting plates 24. In this case, preferably, the fixing plates 11 have a descending width in a downward direction in order to easily insert the side ridges 11b into the fitting plates 24.
The fitting plates 24 may be generated integrally with the connection plates 23 using a molding process or the like. When the connection plates 23 are generated using a plate material, parts of the connection plates 23 may be cut to generate the fitting plates 24. In this case, the fitting plates 24 include extending parts 24a extending from the fixing plates 21, and fitting parts 24b bent from ends of the extending parts 24a to insert the fixing plates 11 of the inner member 10 thereinto. The side ridges 11b may be divided into upper side ridges 11b1 and lower side ridges 11b2. In this case, preferably, the lower side ridges 11b2 have a smaller thickness than the upper side ridges 11b1.

The fixing parts 321 is provided to correspond to an angle of the vertical support members 52 so as to be fixed to the vertical support members 52 in contact with the vertical support members 52.
In detail, one or more through holes 321′ are provided in the fixing parts 321 so as to be screw-coupled and fixed to the vertical support members 52.
The connection parts 323 are configured as frames connected to the fixing parts 321 in parallel with the vertical support members 52.
Since the connection parts 323 are configured as frames, unnecessary waste of raw material may be prevented, a light weight may be achieved, and screws may be easily fastened into the hollow parts 311′.
Separation parts 328 may be provided in the connection parts 323 at locations corresponding to the separation recesses 318 of the ridge 315.
The function of the separation parts 328 is the same as that of the separation recesses 318, and thus a detailed description thereof is not provided herein.
The middle part 325 is provided to interconnect the connection parts 323.
A cut screw hole 325a corresponding to the partial screw hole 315′ of the ridge 315 is provided in a top surface of the middle part 325, and a center screw hole 325b corresponding to the screw hole 313″ of the first middle surface 313 is provided.

The fitting parts 329 are provided in a shape corresponding to the protruding parts 317 and are coupled to the protruding parts 317.
The fitting parts 329 extend in an L shape from the fixing parts 321, and thus may not be easily produced using a conventional mold.
For example, when the outer member 320 having a W shape is produced using a mold having a W-shaped concavo-convex pattern, the fitting parts 329 extending from the fixing parts 321 and then bent to face each other should be additionally generated using a slide mold corresponding to the shape of the fitting parts 329. As such, compared to production of a general bracket, mold size is increased and more time and more processes are required.
However, when the fitting parts 329 are produced, since the connection parts 323 are configured as frames as described above, a small mold may be used.
Since the fitting parts 329 are produced as described above, time, mold size, and waste of raw material may be reduced and thus the outer member 320 may be easily produced.
A bracket using the additionally mountable second member 320b, according to another embodiment, will now be described with reference to

The long screw holes 334 are configured as pipes passing through a middle portion of the fixing parts 332, and are provided at locations corresponding to the screw holes 313″ provided in the middle portion of the first middle surface 313 of the inner member 310, so as to be coupled to screws inserted through the inner member 310.
The fixing plates 336 are provided in a horizontal direction on the top and bottom of the fixing parts 332.
Each fixing plate 336 may include projections 336′ protruding in a direction coupled to the inner member 310. Since the projections 336′ are seated in the top and bottom of the hollow part 313′ of the first middle surface 313 of the inner member 310, a user may easily fix the second member 320b coupled to the pillar 41, to the inner member 310 using screws.

As such, since the side and rear panels 32 and 33 may have a smaller thickness than the pillar members 55, wood may be saved, a product weight may be reduced, and a process for fixing the side and rear panels 32 and 33 for assembly may be omitted.
Preferably, a plurality of inner brackets 10 are spaced apart from each other by a certain distance and mounted along a vertical direction of the pillar members 55, and the side and rear panels 32 and 33 are divided by a height corresponding to the distance between the inner brackets 10. In addition, preferably, to fix the side and rear panels 32 and 33, grooves configured to insert the side and rear panels 32 and 33 thereinto are provided in the vertical support members 52 mounted on the top and bottom upper panels 51.
For reference, herein, the upper panels 51 refer to not only upper panels but also plate materials mounted in a horizontal direction.
As illustrated in
In this case, the assembly method may further include fixing the upper panels 51 by assembling the inner and outer brackets 10 and 20 after the upper panels 51 are inserted, repeating the coupling of the rear and side panels 33 and 32, coupling a cover including the upper panels 51 to the top of the pillar members 55 when a desired number of the upper panels 51 are completely coupled, thereby completing furniture assembly.
In this case, preferably, grooves configured to insert the side and rear panels 32 and 33 thereinto are provided in the vertical support members 52 mounted on the top and bottom upper panels 51, e.g., the cover, thereby fixing ends of the side and rear panels 32 and 33.
Although an inner member and an outer member are separately produced and coupled to a pillar member and vertical support members in the above description, the pillar member and the inner member may be integrally produced or the vertical support members and the outer member may be integrally produced. For example, the pillar member and the inner member may be integrally produced and the vertical support members and the outer member may be integrally produced using a plastic injection process, and then the two may be coupled to each other.
While the present invention has been particularly shown and described with reference to embodiments thereof, it will be understood by one 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 present invention as defined by the following claims.
