DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structural board for furniture which can be used as a tabletop of a desk or a shelf of a display shelf.

[0002]

2. Description of the Related Art Conventionally, as a structural plate for furniture such as a shelf plate of a display shelf, a structural plate manufactured by pressing a sheet metal is widely used. Such sheet metal products are rigid but heavy in weight, and the number of display shelves is large, so that assembly work requires labor. By the way, in recent years,
In order to solve the problems of the sheet metal product, a synthetic resin product was developed, and it became possible to reduce the weight while maintaining rigidity. Such a synthetic resin furniture structural board is made of, for example, an extruded product, and is formed with a hole in the plate portion in the longitudinal direction in order to reduce the weight, and the hole is formed to secure rigidity. A configuration in which a metal reinforcing member is inserted into a hole is known. The stolen hole is a cylindrical hollow portion formed inside with dimensions close to the thickness of the extruded product, and when such an extruded product is viewed from its longitudinal end face,
A plurality is formed in the width direction and penetrates to the other end surface. Correspondingly, the reinforcing member has substantially the same length as the length of the extruded product, and has substantially the same outer dimensions as the internal dimensions of the hole.

[0003]

By the way, the hole of the extruded product as the above-mentioned furniture structural plate extends over the entire length in the longitudinal direction of the extruded product, but has an opening at an intermediate portion thereof. It has a complete cylindrical structure, not a structure. Since the reinforcing member has substantially the same size as the inside diameter of the meat stealing hole for the meat stealing hole having such a structure, when inserted from the end of the meat stealing hole, it is difficult to slide inside the meat stealing hole, It took time to insert the whole. In addition, when members made of different materials such as synthetic resin and metal are used, it is becoming a situation that the materials are sorted and collected for each material at the time of disposal, but the reinforcing member inserted into the hole for removing meat is removed. It was difficult to remove, and it was difficult to separate each material.

On the other hand, in consideration of such a configuration, it is conceivable to make the outer dimensions of the reinforcing member slightly smaller than the inner diameter of the hole for the thickness of the hole, but in this case, the reinforcing member can be easily inserted, but easily removed. It is in a state where it can be obtained, and it is necessary to bond or weld a reinforcing member in order to fix the reinforcing member in the hole. In other words, the work for such fixing increases, and the work process cannot be simplified as a whole.

[0005] An object of the present invention is to solve such a problem.

[0006]

In order to achieve the above object, the present invention takes the following measures. That, furniture construction plate according to the present invention, extruded on both sides near the edge in the width direction of the back surface of the molded synthetic resin plate body an elastic deformable aperture, a metallic reinforcing opening Ri Na by engaging the member, opening in the width direction of the plate body
Each of the opposing surfaces has a groove, and the reinforcing member is provided with a groove.
A ridge is provided at a position corresponding to the portion .

[0007] As a desirable mode of the reinforcing member, a hollow quadrangular prism shape is formed at a predetermined width over the entire length in the longitudinal direction substantially at the center of a surface in contact with a surface opposite to one surface of the opening. An example is provided that has a cut portion formed by cutting, and exhibits elasticity in the width direction of the cut portion.

[0008]

With such a structure, the groove of the plate body is
When the reinforcing member is pushed into the opening portion from the opening direction, the opening portion is elastically deformed, the groove portion elastically engages with the ridge of the reinforcing member, and portions near both side edges in the longitudinal direction of the plate are reinforced by metal. You. In this case, since the opening of the reinforcing member is elastically deformed, it is not necessary to push the reinforcing member from the longitudinal end portion thereof, so that the reinforcing member can be easily attached to the plate.

Further, if the reinforcing member is formed in the shape of a hollow quadrangular prism having a cutout formed by cutting out at a predetermined width over the entire length in the longitudinal direction, and is configured to exhibit elasticity in the widthwise direction of the cutout, Since the opening and the reinforcing member engage with each other by the elastic force, a stronger engagement state can be maintained.

Further, since the reinforcing member is only held by the plate body with an elastic force, a force is applied in a direction for releasing the engagement between the plate body and the reinforcing member, that is, the reinforcing member is reinforced in the opening direction of the opening of the plate body. When the member is pulled, the engagement between the reinforcing member and the plate can be easily released, and the reinforcing member can be removed from the opening. Therefore, the plate made of synthetic resin and the reinforcing member made of metal can be easily separated, and each can be separated and reused as a resource, or can be efficiently disposed.

[0011]

An embodiment of the present invention will be described below with reference to the drawings.

A top plate 1 as a furniture structure shown in FIGS.
A flat plate member 2 made of synthetic resin, both surfaces of which are extruded flat, a reinforcing member 3 made of sheet metal disposed on the lower surface of the plate member 2 in the longitudinal direction, and fitted on both end surfaces of the plate member 2. And an end cap 4.

The plate body 2 has a rectangular hole 5 in the longitudinal direction formed in the inside thereof. The meat hole 5 is a cylindrical hollow portion, and when viewed from the end face in the longitudinal direction of the plate body 2, a plurality of, for example, six, holes are formed in the width direction and penetrate to the other end face. Further, an elastically deformable opening 6 is provided near the front end and the rear end in the width direction on the back side. The opening 6 has a rectangular shape as viewed from the side and has an opening at the bottom, and is formed in the same shape from one end surface to the other end surface, similarly to the meat hole 5.

As shown in the enlarged view of FIG. 2, the opening 6 is provided with a groove 8 in which a ridge 7 formed on the front and rear surfaces of the reinforcing member 3 described later is fitted at a position corresponding to the ridge 7. It is.

The reinforcing member 3 is formed by bending a sheet metal, has a hollow rectangular column shape, and has substantially the same outer shape as the inside of the opening 6 so as to be fitted into the opening 6 of the plate 2. It has dimensions. At a substantially center of a surface in contact with a surface opposite to one surface of the opening 6, a predetermined width, for example, about 1/3 of a width in the front-rear direction of the reinforcing member 3, is cut over the entire length in the longitudinal direction. It has a resection part 9 consisting of: Due to the cutout portion 9, the reinforcing member 3 exhibits elasticity outward in the width direction of the cutout portion 9.
Further, on the outer surface before and after the reinforcing member 3, a ridge 7 projecting over the entire length in the longitudinal direction is formed. Since the vicinity of the left and right ends of the reinforcing member 3 is a leg and a mounting portion (not shown), a nut member (not shown) is fixed to the corresponding leg mounting position in advance by welding or the like.

The end cap 4 is made of synthetic resin and includes a plate-shaped main body 10 having the same shape as the plate body 2 in a side view, and a fitting portion 11 integrally formed on one side of the main body. is there. When the main body 10 is attached to the plate 2, the plate 2
Front, back, front, and back. The fitting portion 11 has a shape that can be fitted to the reinforcing member 3, that is,
It is substantially the same rectangular shape in side view as the space formed by the inner surface of the reinforcing member 3 and has a size slightly smaller than the space. The end cap 4 is attached to the plate 2 by fitting the fitting portion 11 to the reinforcing member 3 and is for protecting the left and right ends of the plate 2 which is the cut end face of the extrusion molding. .

In such a configuration, to assemble the top plate 1, the reinforcing member 3 is engaged with the plate 2, and then the end caps 4 are fitted into both side ends of the plate 2. Specifically, to engage the reinforcing member 3 with the plate 2, the reinforcing member 3 is pushed into the opening 6 of the plate 2 from below with the cutout 9 facing upward. Then, the reinforcing member 3 exerts elasticity in the width direction of the cutout 9 and the length in the width direction is temporarily reduced. At this time,
The opening 6 is elastically deformed and temporarily expands in the width direction when viewed from the end face in the longitudinal direction. Then, when the ridge 7 is fitted into the groove 8 and the surface of the reinforcing member 3 having the cutout 9 abuts against the surface of the opening 6 opposite to one surface, the reinforcing member 3 and the opening 6 are connected. Return to the shape before elastic deformation. In this way,
The reinforcing member 3 easily fits into the opening 6, and the plate 2 and the reinforcing member 3 are engaged. Thereafter, the fitting portion of the end cap 4 is fitted to the inner surface of the auxiliary member 3, and the end cap 4 is attached to the plate 2. With such a configuration, the engagement between the reinforcing member 3 and the plate 2 becomes stronger by fitting the ridge 7 into the groove 8. Further, since the reinforcing member 3 can be easily engaged with the plate 2 and the end cap 4 can be easily attached to the plate 2, the time and labor required for assembling the top plate 1 are reduced. It will be slight.

In order to disassemble the top plate 1, the reverse procedure of the assembly may be performed, that is, the end cap 4
Is removed from the plate 2, the reinforcing member 3 is separated from the plate 2. More specifically, the main body 10 is pulled in a direction away from the plate 2, the fitting portion 11 is pulled out from the auxiliary member 3, and the end cap 4 is removed from the plate 2. Next, a force is applied in a direction to release the engagement between the plate 2 and the reinforcing member 3, that is, the reinforcing member 3 is applied in the opening direction of the opening 6 of the plate 2.
Is pulled, the fitting of the ridge 7 and the groove 8 and the reinforcing member 3
The engagement between the reinforcing member 3 and the plate 2 can be released by disengagement of the reinforcing member 3 from the opening 6. Therefore, the plate 2, the reinforcing member 3, and the end cap 4 made of different materials can be easily separated without complicated work, and the respective members can be reused or efficiently disposed. Can be provided.

Further, since the plate 2 is formed by extrusion molding, it is possible to manufacture the plate 2 having various dimensions in the extrusion direction with the same die. As a result, capital investment for dies and the like can be reduced, and the manufacturing cost can be reduced.

In addition, since the plate 2 is formed with a plurality of the pits 5, it is light in weight for its size. Moreover, since the reinforcing members 3 are engaged in the longitudinal direction in the vicinity of the front end and the rear end of the back surface of the plate 2, sufficient rigidity is secured.

Further, since a nut member can be fixed to the reinforcing member 3, a leg can be attached via the nut member, and a place for attaching the leg can be easily secured. In this case, since the reinforcing member 3 is made of sheet metal, the reinforcing member 3 has sufficient strength even when the leg is attached.

The present invention is not limited to the embodiment described above. When the present invention is used as a shelf board, instead of fixing a nut member to the reinforcing member 3, a shelf claw is used. May be provided in the slit. With such a configuration, the shelf board is attached via the highly rigid metal reinforcing member 3, and the strength of the shelf board can be maintained.

In addition, the configuration of each section is not limited to the illustrated embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0024]

According to the present invention, as described in detail above, an opening having a groove is provided on the other surface of the plate body, and the protrusion of the reinforcing member is elastically engaged with the groove of the opening. In addition, the reinforcing member can be integrated with the plate without being inserted from the longitudinal end of the plate, and the mounting operation can be significantly facilitated. Also, when the assisting member is pressed against the opening with the cut portion facing the back of the opening, the assisting member having elasticity and the plate body are each elastically deformed, so that the assisting member is elastically engaged with the opening. It can be easily fitted.

In addition, since the reinforcing member is attached to the plate by elastic engagement, the engagement between the plate and the reinforcing member can be easily released, and the plate made of synthetic resin and the reinforcing member made of metal can be connected. Can be easily separated. Therefore, the plate member and the reinforcing member made of different materials can be separated from each other without any troublesome work, and each member can be used for reuse or efficient disposal.

Furthermore, since the plate is formed by extrusion molding, it is possible to manufacture plates having various different dimensions in the extrusion direction using the same mold. As a result, capital investment for dies and the like can be reduced, and the manufacturing cost can be reduced.

According to such a configuration, the versatility of the plate can be improved by processing the nuts and the mounting holes only on the reinforcing member. Can be supported.
