DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention embodied in a kotatsu top plate will be described below with reference to FIGS.

As shown in FIG. 1, a top plate 11 is interposed between a main top plate 12 having a square plate shape as a polygonal plate shape and an auxiliary top plate 13 having the same square shape as the main top plate 12. A top plate body 15 comprising a reinforcing member 14 mounted thereon;
A decorative member 16 is attached to each of the corners. In the top plate 11, a reinforcing member 14 and an auxiliary top plate 13 are disposed inside a side wall 12a of the main top plate 12, and a top plate body 15 is formed by the decorative member 16 and the side wall 12a.
Are formed so that the internal structure of them is invisible.

First, the main top plate 12 will be described. As shown in FIG. 1, the main top plate 12 is a flat square steel plate (a so-called color steel plate) in which an iron plate is colored in a desired color.
Is formed by press molding. Each corner of the main top plate 12 is chamfered to form a planar arc.
On the main top plate 12, four peripheral edges of the steel plate excluding the four corners are bent at substantially right angles to the back surface (lower surface), respectively, to form a side wall 12a. Also, as shown in FIG.
A main top plate 1 is provided at a tip portion along the length direction of each side wall 12a.
After extending horizontally inward for a predetermined length toward the inside of 2, the reinforcing ribs 12b are formed by bending again at a substantially right angle to the surface (upper surface) side, that is, by bending the tip of the side wall 12a twice. The length of the side wall 12a along the width direction (vertical direction) is D1.

The auxiliary top plate 13 will be described. As shown in FIG. 1, the auxiliary top plate 13 is formed by press-forming the above-described square-shaped steel plate colored in a desired color. Each corner of the auxiliary top plate 13 is chamfered to form a planar arc. A reinforcing wall 13a is formed on the auxiliary top plate 13 by bending the four peripheral edges of the steel plate excluding the four corners to the surface (upper surface) side at substantially right angles. The length L1 along the length direction (lateral direction) of the side wall 12a and the length L2 along the length direction (lateral direction) of the reinforcing wall 13a are set to be the same.

The reinforcing member 14 will be described. As shown in FIG. 1, the reinforcing member 14 is formed by pressing the steel plate having a flat rectangular shape into a plurality of ridges 14a extending parallel to one side of the steel plate. It is bent and formed so as to be formed as a convex part. Since each ridge 14a is formed by bending a corner forming the ridge 14a at a substantially right angle, the upper surface of each ridge 14a is formed in a horizontal plane. Each corner of the reinforcing member 14 is chamfered to form a planar arc. The weight of the entire top plate 11 can be appropriately adjusted and set by adjusting the thickness of the reinforcing member 14 to be thin or thick.

Referring to the decorative member 16, as shown in FIG. 3, the decorative member 16 made of a synthetic resin material has a substantially U-shape as viewed from the side, and as shown in FIG. Is formed. As shown in FIG. 3, the distance between the upper and lower surfaces of the facing member 16 is set to W1, and the distance W1 is determined so that the facing member 16 is externally fitted to each side wall 12a and the corner of the top plate body 15. The side wall 12a is made possible.
Is set to be the same as the length D1. In a state where the decorative member 16 is externally fitted to each corner of the top plate main body 15, the edge of the adjacent side wall 12a and the main top plate 12, the auxiliary top plate, Each corner of the reinforcing member 13 and the reinforcing member 14 is set so as to be covered.

Now, the top plate 11 formed by using the main top plate 12, the reinforcing member 14, the auxiliary top plate 13, and the decorative member 16 will be described together with a manufacturing method. First, as shown in FIG. 5, the reinforcing member 14 and the auxiliary top plate 13 are accommodated inside the four side walls 12a of the main top plate 12, that is, in the space surrounded by the side walls 12a. In this storage state, the main top plate 1
2. Each corner (only one corner is shown in FIG. 5) of the auxiliary top plate 13 and the reinforcing member 14 respectively correspond to upper and lower sides, and as shown in FIG. 3, the outer surface of each reinforcing wall 13a and the outer surface of the reinforcing rib 12b And the upper edge of the reinforcing wall 13a is in contact with the back surface (lower surface) of the main top plate 12. Further, as shown in FIG. 4, the movement of the auxiliary top plate 13 within the main top plate 12 is restricted by the contact between the reinforcing ribs 12b and the reinforcing walls 13a.

The back surface (lower surface) of the main top plate 12, the surface (upper surface) of each ridge 14a of the reinforcing member 14, and the auxiliary top plate 1
3 and the back surface (lower surface) of the reinforcing member 14 located between the adjacent ridges 14a are adhered by an adhesive, so that the main top plate 12 and the reinforcing member 14, and the reinforcing member 14 and the auxiliary top plate 13 Are partially in contact. The main top plate 12, the reinforcing member 14, and the auxiliary top plate 13 are integrated with each other according to the accommodation state and the adhesion state to form the top plate main body 15. In addition, the reinforcing rib 1
The back surface of 2b and the back surface of the auxiliary top plate 13 are flush.

Subsequently, the four decorative members 16 are fitted to the respective corners of the top plate main body 15 until the outer surfaces of the side walls 12a of the top plate main body 15 abut against the inner back surfaces on both sides of each decorative member 16 respectively. . At the same time, the outer surface of the side wall 12a, the corner surface of the main top plate 12, and the corner back surface of the auxiliary top plate 13 are adhered to the inner surface of the decorative member 16 with the adhesive to the four corners of the top plate body 15. Each decorative member 16 is attached. In a state where the decorative member 16 is attached to the corners of the top plate main body 15, the corresponding corners of the main top plate 12, the reinforcing member 14, and the auxiliary top plate 13 that constitute each corner of the top plate main body 15 are the decorative member 1
6 is held by the outer fitting. Then, as shown in FIGS. 2 to 4, the decorative member 16 is attached to each corner of the top plate main body 15 to form the top plate 11.

Decorative member 1 attached to each corner of top plate 11
6 covers the internal structure of the top plate main body 15 so as to be invisible. In addition, the inner structure of the top plate main body 15 is not visible due to the side walls 12a of the four peripheral edges excluding the corners of the top plate 11. That is, the four peripheral edges of the top plate 11 excluding the four corners are constituted by the side walls 12a, and the four corners are constituted by the decorative members 16 attached to the four corners of the top plate body 15. Is done. The side wall 12a and the decorative member 16 form a peripheral portion of the top plate 11, and the reinforcing member 14 and the peripheral edge of the auxiliary top plate 13 arranged inside the peripheral portion are covered with the side wall 12a and the decorative member 16. Is done. As shown in FIG. 6, the top plate 11 is used for the kotatsu 17 with the main top plate 12 facing the front.

According to the top plate 11 and the method of manufacturing the same, the following features can be obtained. The side walls 12a are integrally formed on the main top plate 12 constituting the top plate main body 15, and the decorative members 16 are attached to each corner of the top plate main body 15, so that the top wall is formed by the side walls 12a and the respective decorative members 16. The internal structure of the plate body 15 was made invisible. Therefore, unlike the related art in which a single band-shaped decorative member 16 is adhered to the top plate main body 15 while being adhered along the peripheral edge and the corner of the top plate main body 15, the decorative member 1 for the top plate main body 15 is different.
6 can be easily attached and the top plate 11 can be easily manufactured. Further, the peripheral portions of the reinforcing member 14 and the auxiliary top plate 13 are reliably covered by the side walls 12a and the decorative member 16, so that the design of the top plate 11 can be prevented from being deteriorated.

A decorative member 16 previously formed in an arc shape along the corner of the top plate body 15
In order to attach the decorative member 16 to each of the corners, one decorative member 16 is manually folded along the corner of the top plate body 15 to make the decorative member 1
Unlike the conventional case in which distortion such as distortion or displacement of the top plate 6 has occurred, the top plate 1
The lowering of the design property of the corner portion 1 can be prevented.

The decorative member 16 is formed in an arc shape capable of covering one corner of the top plate body 15. for that reason,
Unlike the conventional case in which the decorative member 16 is formed in a band shape capable of covering the entire peripheral edge of the top plate body 15, the length of the decorative member 16 along the longitudinal direction in the planar shape is shortened to make the decorative member 16
Can be downsized. Therefore, the manufacturing cost can be reduced by downsizing the manufacturing machine,
1 can be reduced.

Further, since the decorative member 16 is used by being attached only to the corners of the top plate main body 15, it can be used according to a plurality of types of sizes of the top plate main body 15. Therefore, the development dimension in the length direction of the decorative member 16 changes for each size of the top plate main body 15, and unlike the conventional case where it is necessary to manufacture the decorative member 16 for each size of the top plate main body 15, The range of use can be expanded.

Since the top plate body 15 and the decorative member 16 may be adhered by applying an adhesive to the four decorative members 16, the single decorative member 16 and the entire peripheral edge of the top plate body 15 may be separated. Unlike the conventional method of bonding with an adhesive, the amount of the adhesive used can be reduced, which can contribute to a reduction in the manufacturing cost of the top plate 11.

The back surface of the main top plate 12, the surface of each ridge 14a of the reinforcing member 14, and the back surface of the reinforcing member 14 located between the surface of the auxiliary top plate 13 and the adjacent ridge 14a are respectively bonded with an adhesive. Have been. Therefore, for example, when the upper surface of the top plate 11 is hit, no sound is generated due to the contact between the main top plate 12 and the reinforcing member 14, so that the use state of the top plate 11 can be prevented from lowering.

In the top plate 11, the decorative member 16 slightly protrudes from the top plate body 15, that is, the back surface of the auxiliary top plate 13. Therefore, when the comforter (not shown) is hung on the kotatsu 17 and the top plate 11 is placed on the comforter, the load of the top plate 11 acts on the position of the comforter corresponding to the four decorative members 16. Therefore, the top plate 11 can be made harder to move on the comforter than when the load of the top plate 11 acts on the comforter from the entire surface of the top plate 11. Further, a slight gap is formed between the back surface of the top plate 11 and the comforter by the decorative member 16. Therefore, unlike the conventional case in which the decorative member 16 is provided over the entire circumference of the top plate main body 15, it becomes easy to put a finger between the top plate 11 and the comforter,
The work of lifting the top plate 11 from the comforter can be easily performed.

Corresponding corners of the main top plate 12 and the auxiliary top plate 13 are sandwiched by decorative members 16, respectively.
Therefore, the force in the direction in which the main top plate 12 and the auxiliary top plate 13 separate from each other by the decorative members 16 can be suppressed.

The main top plate 12, the reinforcing member 14, and the auxiliary top plate 13 are each formed by pressing a steel plate. Therefore, as compared with the case where each member is molded by a synthetic resin material or the like, the side wall 12a, the reinforcing wall 13a,
a, the reinforcing ribs 12b and the like can be easily formed, and the manufacturing process of the top plate 11 can be simplified.
1 can contribute to a reduction in manufacturing cost.

Since the reinforcing member 14 is formed of a steel plate, the weight of the top plate 11 can be adjusted by changing the thickness of the steel plate. Therefore, the top plate 11 having a desired weight can be easily set and manufactured. Further, by reducing the plate thickness, it is possible to contribute to a reduction in the manufacturing cost of the top plate 11.

The top plate 11 is formed by the main top plate 12 made of steel plate, the reinforcing member 14, the auxiliary top plate 13, and the decorative member 16 made of a synthetic resin material. Only the top plate body 15 can be provided for recycling without further separation. Therefore, the decorative member 16 made of a melamine resin is removed, and the top plate body 15 composed of a flat plate made of a synthetic material of wood and a synthetic resin and a melamine decorative plate is separated into a wooden material and a synthetic resin material for recycling. Unlike the conventional method, the top plate 11 can be easily disposed of.

The abutment of the reinforcing wall 13a on the back surface of the main top plate 12 imparts a required strength to a position corresponding to the four peripheral edges of the auxiliary top plate 13 on the back surface of the top plate 11 to provide the required strength.
Deformation of the peripheral portion and the like can be prevented.

A reinforcing rib 12b is formed by bending the tip of the side wall 12a twice. Therefore, the side wall 12
a with respect to the external force from above the top plate 11 as compared to the case where the reinforcing rib 12b is not formed at the tip edge of the reinforcing rib 1b.
2b imparts necessary strength to the side wall 12a and
Can be prevented from being deformed.
