Description

Split-type back plate for furniture with a fixed structure of a knock-down method using an expansion pressing tool}

The present invention relates to a split back plate of various storage furniture, and more particularly, in fixing the back plate of a prefabricated storage furniture, a complete knockdown structure for a split back plate is assembled by using a connection profile of a mutually engaging structure and an expansion presser. Not only does it produce hyper-degradability, but it also provides continuous expansion and pressure fixing power to the split back plate, thereby fundamentally blocking the back plate's play or wobbling, and at the same time, the stable and solid mutual fixing force increases the stability of assembly and installation of knockdown furniture. It relates to a split back panel for furniture that can be improved.

In general, furniture for storing various items such as various drawers, chests of drawers, or cabinets has the shape of a hexahedron as a whole, and is composed of a single or divided opening door at the front, side plates on both sides, and a back plate at the rear, with an upper panel and It is made of a combination of floor panels and the like.

Most of these storage furniture in various shapes and types go through the work of connecting and fixing each panel using a nailer pin in the factory, and in the case of an opening and closing door, it is mounted using a hinge, and in the case of a back panel, published patent No. 10- As shown in No. 2007-0029789, it is common to assemble and produce in the form of inserting each end of the back plate into each fitting groove formed on the side plate, top panel, and bottom panel and combining them.

In addition, instead of manufacturing finished products in factories and delivering them to consumers as in the past, each panel is produced in a factory and delivered to consumers before assembly, allowing consumers to directly connect and assemble each panel. Knock-down furniture, which allows furniture to be completed through a process, is becoming widely popular, and the knock-down furniture can significantly reduce logistics costs such as storage, delivery, and handling, as well as increase furniture productivity at the manufacturing site. At the same time, it is possible to provide convenience and economy in a form that can satisfy both producers and consumers by enabling consumers who purchased them at low prices to assemble and install them directly on site.

As shown in Patent Publication No. 10-2013-0060417, this prefabricated knockdown furniture consists of a vertical board built on the left and right sides of wood, a bottom plate blocked at the bottom, a top plate positioned at the top, and a back plate that blocks the back. In the furniture in which assembly grooves are respectively dug in the vertical plate body, the bottom plate, and the top plate so that the back plate is fitted and assembled, the vertical plate body, the bottom plate, and the top plate are respectively drilled with fastening holes communicating with the position of the assembly grooves , Prefabricated furniture has been devised in which screws are inserted through these fastening holes so that the back plate is fastened and fixed to the vertical plate body, the bottom plate, and the top plate, respectively.

Next, in the case of storage furniture having a double-sided opening and closing door form, it is common to produce by applying a back plate divided into both sides rather than using a single-plate back plate because the storage furniture itself is relatively bulky. In production and assembly, if the back plate of a single panel is used, the handling of the panel itself and the supply and demand of materials are very poor, as well as the inefficiency in the assembly process. universal

Therefore, the back plate of the storage furniture forms the rear part of the storage furniture in the form of connecting mutually opposite ends of the divided back plates to the joint member using a separately provided joint member having an 'H' shape in cross section, Both ends of the back plate are mutually coupled to the divided back plate as described above by inserting them into the fitting grooves formed on each side plate. It is true that it overcomes all the problems of the back plate in the form of a large single plate by firmly fixing it using a Takapin or fixing bolt.

In addition, a first board for furniture, as in Patent Registration No. 10-1558218 recently entered; a second board member for furniture disposed horizontally to the first board member; It consists of a connecting member for interconnecting the first and second plates arranged in the horizontal direction, the connecting member is made of an adhesive resin and is fixedly adhered to the first and second plates, and the connecting member is made of an adhesive resin. A furniture board having a folding structure characterized by being made of a material having elasticity so as to be bent when the second board member is folded with respect to the first board member and a manufacturing method thereof have been devised and registered.

However, the connection and fixing structure of the split back plate for storage furniture using the joint member of the 'H' cross section as described above has a weak mutual fixing force between the side plate and the back plate, so that the back plate and The work of coupling and fixing the side plates to each other must be accompanied, and due to the mutual gap or gap between the joint member and the back plate and between the side plate and the back plate, the wobble or rocking in the center of the back plate, which depends on the vertical joint member, is very severe. However, as the fixing force of the back plate is weak, the solid support fixing force between the side plates is weakened or lost, resulting in a decrease in the overall structural stability of the storage furniture and a decrease in its useful life.

Moreover, as described above, since the Taka pins or fixing blocks used to strengthen the fixing power of the split back plate will be very difficult for consumers to directly realize at home or in the office, so that they can be easily assembled and disassembled in the field It has disadvantages that go against the purpose and trend of knockdown furniture.

Korean Patent Publication No. 10-2007-0029789 (published on March 14, 2007) Korean Patent Publication No. 10-2013-0060417 (2013.06.10. Publication) Korean Registered Patent No. 10-1558218 (2015.10.01. Registration)

First, the storage furniture 100 having the split back plates 110 and 110' of the present invention typically includes a pair of side plates 120 and 120' spaced apart from the front opening and closing door, a top plate, and a bottom plate. In the case of the split back plate 110 (110 ') as described above, both ends are inserted into the fitting grooves formed on the inner surface of the side plate 120 (120 '), and the split back plate ( The upper and lower ends of the 110) (110') are inserted into the fitting grooves formed on the inner surfaces of the top plate and the bottom plate, respectively, so that the split back plate 110 (110') is inserted into these side plates, the top plate, and the bottom plate. It has an assembled form, and in the case of mutually opposite ends of each of the split back plates 110 and 110', the expansion pressure spheres 200 and 200' and the connection profiles 300 and 300' as in the present invention ) has a structure connected by

Accordingly, at the upper and lower ends of the mutually opposite ends of the split-type back plates 110 and 110' as described above, the first pressing fixture 210 and the second pressing fixture 220 having an interlocking structure are expanded pressers ( 200) (200') are respectively formed, and between these expansion presses (200) (200'), a connection profile of a mutually engaging structure to be coupled to the opposite end of the split back plate (110) (110') (300) (300') are formed by combining each other, and the split type back plate (110) (110') It is designed to make a connection.

Here, the expansion presser 200 (200') is easily coupled to the split back plate 110 (110') by the assembly installer, and at the same time, the expansion force of the extension presser 200 (200') is applied to the split back plate 110. ) (110 '), resulting in the split back plate 110, 110' due to the continuous outward pressing force acting on the split back plate 110, 110', as well as the interconnection fixing force of the split back plate 110 (110') itself. (110) (110') and the side plate (120) (120') serves to increase the coupling fixing force.

In addition, the connection profile 300, 300' fills the gap between the split back plates 110, 110' receiving forces to open outward from each other by the expansion pressure spheres 200, 200'. At the same time, it serves to connect these split back plates 110 and 110 ', and has the effect of preventing the split back plate 110 and 110' from rolling or swinging through the interlocking structure.

Therefore. The insertion grooves 211, 221 and the insertion protrusions ( 212 and 222 are formed in correspondence with each other, and on the other side of the first press fixture 210 and the second press fixture 220, an assembly groove for inserting the end of the split back plate 110 (110 ') ( 213 and 223 are formed, respectively, and a screw shaft 216 formed on one side of a separate pressing rotation body 215 is coupled by forming a screw hole 214 in the transverse direction in the first pressing fixture 210 It is made up so that

In addition, at the upper and lower ends of the mutually opposite sides of the split-type back plates 110 and 110' as described above, a square receiving groove for inserting one side of the first press fixture 210 and the second press fixture 220 (111) (111') is formed, and the assembly grooves 213 and 223 of the first press fixture 210 and the second press fixture 220 are the first press fixture 210 and the second press fixture 210. It is configured in a "c" shape connecting the upper, lower and outer ends of the press fixture 220 so that the inner ends of the square receiving grooves 111 and 111' interlock with the assembly grooves 213 and 223. As configured to be, the first pressing fixture 210 and the second pressing fixture 220 coupled to the split back plate 110 (110 ') are mutually coupled from the split back plate 110 (110 '), It is configured to be indented without flow.

In particular, a locking groove 215a is formed on the outer surface of the pressing rotating body 215 as described above, and on one side of the second pressing fixture 220 corresponding to the pressing rotating body 215, the locking groove ( 215a), the first pressing fixture 210 and the second pressing fixture 210 on both sides due to mutual coupling of the locking groove 215a and the locking projection 220a. The fixture 220 is not only more firmly engaged and locked, but also the second press fixture 220 in the process of rotating the press rotation body 215 of the first press fixture 210 and protruding outward. Due to the mutually coupled state, problems such as slipping of the first pressing fixture 210 and the second pressing fixture 220 can be prevented, so with more powerful force, the split back plate 110, 110' on both sides ) can be pushed outward and fixed.

In addition, as the pressing rotating body 215 as described above is configured by further forming a tool insertion groove 215b on the outer circumferential surface, the pressing rotating body 215 is rotated to divide the back plate 110, 110'. In the process of providing the pressing force, a driver or a pin or rod may be inserted into the tool insertion groove 215b to rotate the pressing rotating body 215 more strongly through this.

Subsequently, the pair of connection profiles 300 and 300' respectively coupled to the split back plate 110 and 110' are made in a single form and assembled to face each other, and one side has a fitting groove 301 along the vertical longitudinal direction. ) And a fitting protrusion 302 is formed, and on the other side, a coupling groove 303 is formed so that the end of the split back plate 110, 110' is inserted.

Therefore, by tightly inserting the end of the split back plate 110, 110' into the coupling groove 303, the connection profile 300, 300' for the split back plate 110, 110' The coupling is made, and as a pair of connection profiles 300 and 300' having the same shape are inserted into the ends of the split back plates 110 and 110' facing each other, the pair of connection profiles ( 300) (300') is to have an assembly form in which the fitting groove 301 and the fitting protrusion 302 face each other.

Accordingly, when the mutually opposed connection profiles 300 and 300' are coupled, the fitting groove 301 and the fitting protrusion 302 of the connection profile 300 on one side are the fitting protrusions formed on the connection profile 300' on the other side ( 302) and the fitting groove 301 are coupled to each other in correspondence with each other so that they can be coupled in an interlocking form.

This interlocking structure induces an increase in the connection holding force between the split back plate 110, 110' and the connection profile 300, 300', thereby creating a mutually strong bonding force, as well as being fixed in a form that opens to each other. Considering the characteristics of the split-type back plate 110 (110'), even if a predetermined gap or play occurs between the split-type back plate 110 (110'), the mutual coupling length between the fitting groove 301 and the fitting protrusion 302 Within the range, it is possible to maintain a solid and stable connection without separation or gaps.

Therefore, looking at the fixing process for the split back plate 110 (110') of the present invention sequentially, as shown in Figs. The press fixture 210, the second press fixture 220, and the connection profiles 300 and 300' are coupled, respectively, and the first press fixture 210 and the second press fixture 220 facing each other. ) and the connection profiles 300 and 300' as shown in FIG. 11, the connection work for the divided back plates 110 and 110' in a separated state is performed.

At this time, the insertion groove 211 and the insertion protrusion 212 of the first pressure fixture 210 are interlocked and coupled to each other by the insertion projection 222 and the insertion groove 221 of the second pressure fixture 220, The pair of connection profiles 300 and 300' also have the fitting groove 301 and the fitting protrusion 302 facing each other and interlocking, so that the separated split back plates 110 and 110' are in a stable and solid coupling state. It will be done.

In addition, the outer ends of the split back plates 110 (110') are inserted into fitting grooves (numerals in the drawing are omitted) formed in the side plates 120 (120') constituting the storage furniture 100. Accordingly, assembly and temporary fixation of the split back plate 110, 110' is performed.

In this state, the assembler or the user rotates the pressing rotating body 215 coupled to the first pressing fixture 210 of the expansion pressing sphere 200 (200') in a counterclockwise direction to rotate the pressing rotating body 215. ) is adjusted so that it protrudes toward the second pressing fixture 220, and the outer end of the pressing rotating body 215 continuously rotates the pressing body 215 in a state in which the second pressing fixture 220 interferes. Due to the rotational protruding force, the first pressing fixture 210 and the second pressing fixture 220 will receive a force to open each other as shown in FIG. 12, and these first pressing fixtures 210 and As the two pressure fixtures 220 are opened, the split back plates 110 and 110' to which they are coupled are also subjected to force to open each other in the outward direction.

Therefore, the outer ends of the split back plates 110 and 110' spread outward in the opposite direction to each other by using the continuous rotational protrusion force of the rotational pressure body 215. While being strongly adhered to the fitting grooves of the side plates 120 and 120', mutually firm adhesion and fixing force can be obtained, and the continuous and strong outward pressing force acting on the divided back plates 110 and 110' is the divided back plate ( 110) (110') serves to increase the mutual support and fixing force, and eventually the split back plate 110 (110') and the side plate 120 (120') are combined and fixed with strong force. that can be kept stable.

In particular, the first pressing fixture 210 and the second pressing fixture 220 are coupled by mutual fitting of the insertion grooves 211 and 221 and the insertion protrusions 212 and 222 as described above. , The connection profiles 300 and 300' are also coupled in a state of mutual engagement between the fitting groove 301 and the fitting protrusion 302, and the split back plate 110, 110' has a force that spreads outward. Even if they are spaced apart and fixed, these insertion grooves 211, 221, insertion protrusions 212, 222, fitting grooves 301, and fitting protrusions 302 have a length sufficient to prevent separation or separation from each other. (110) There will be no gap or play between (110').

In addition, compared to the connection profiles 300 and 300', the expansion pressure sphere 200 and 200' has a pressure rotation body 215, considering that it is relatively large in size, the split type back plate 110 ( 110') after forming the square receiving grooves 111 and 111', the first pressing fixture 210 and the second pressing fixture 220 are recessed and inserted into the square receiving grooves 111 and 111' By configuring, as shown in FIG. 13, the expansion pressure spheres 200 and 200' and the connection profiles 300 and 300' are a continuous form of fixing means in the upward and downward directions, creating a beautiful and concise exterior at the same time. A strong outward pressing force can be continuously applied to the split back plates 110 and 110' even with the simple rotational action of the pressurizing rotating body 215 exposed to the outside, so that a more robust and stable coupling and fixation can be maintained. do.

Conversely, when the pressure rotation body 215 of the first pressure fixture 210 as described above is rotated in the reverse direction, that is, clockwise, the screw shaft 216 of the pressure rotation body 215 is the first pressure fixture ( 210) is further inserted into the inside of the screw hole 214, and the force pushing the second pressing fixture 220 is lost, and when the pressing rotating body 215 continues to rotate, the split back plate 110, 110 Since the entire force pushing the ') will be weakened and lost, the play between these split back plates 110, 110' and the side plates 120, 120' and the gap between the split back plates 110, 110' Through this, the split back plate 110, 110' can be easily separated and disassembled.

As a result, for the entire storage furniture 100, the split back plates 110 and 110' themselves realize a perfect knockdown assembly structure, including the side plates 120 and 120' of the storage furniture 100. Therefore, when the assembly structure of the knockdown method is applied to the top plate and the bottom plate, it can be completed as a perfect knockdown furniture.

In addition, in the case of storage furniture with a relatively long height, as shown in (a) of FIG. It will be possible to design and assemble the back plate 110 (110') so that the outside pressing force acts as a whole, and in the case of a storage furniture 100 with a partition or a relatively wide and large storage furniture, FIG. 14 (b) It will be possible to construct and assemble the expansion pressure spheres 200 and 200' and the connection profiles 300 and 300' in the form of separate upper and lower parts, as shown in FIG.

As a result, the split back plate having the assembly structure of the present invention can be easily assembled and disassembled for the split back plate 110, 110' by any producer, installer, or consumer, so that furniture with a perfect knockdown structure can be realized. Due to the expansion pressing spheres 200 and 200' that continuously provide pressing force in the outward direction, the split back plate 110 and 110' does not require a separate tack pin fixing or block fixing, so productivity improvement and assembly performance It will be a very useful invention that can satisfy both economic feasibility and efficiency.
