[0001] The present invention relates to a support unit for a top plate of furniture with a top plate such as a desk or a table.

Background Art

[0002] In order to support the top plate of furniture with a top plate such as a desk or a table, a table has been proposed and put into practical use in which a reinforcing beam is spanned between support legs that support the top plate so as to be attached to the lower surface of the top plate (see, for example, Patent Documents 1 and 2).

Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the tables disclosed in Patent Documents 1 and 2, in which a reinforcing beam is spanned between support legs that support the top plate so as to be attached to the lower surface of the top plate, the reinforcing beam is attached via a mounting plate fixed to the top plate for attaching the support legs. And in these tables, since the attachment position and direction of the reinforcing beam with respect to the mounting plate are specified, the versatility with respect to a top plate having a planar shape other than a rectangle (square or rectangle) is poor, and in a top plate having a planar shape other than a rectangle, it may be difficult to position the reinforcing beam close to the outer periphery of the top plate effective for supporting the top plate.

[0005] In view of the problems associated with the fact that in a table in which a reinforcing beam is bridged between support legs that support the top plate so as to be attached to the lower surface of the top plate, the attachment position and direction of the reinforcing beam with respect to the attachment plate are specified, an object of the present invention is to provide a support unit for a top plate that can give freedom to the attachment position and direction of the reinforcing beam with respect to the attachment plate.

Means for Solving the Problems

[0006] To achieve the above object, a support unit for a top plate according to the present invention is a support unit for a top plate that attaches support legs for supporting the top plate and bridges a reinforcing beam between the support legs so as to be attached to the lower surface of the top plate, wherein the support unit includes an attachment plate fixed to the top plate for attaching the support legs, and a reinforcing beam having both ends attached to adjacent attachment plates, the attachment plate is formed with an attachment portion for attaching the reinforcing beam, and the reinforcing beam is configured to be attachable to the attachment portion of the attachment plate in an arbitrary direction.

[0007] In this case, the attachment portion may be cylindrical, the end portion of the reinforcing beam may be arc-shaped, and the center may be attached by a screw.

[0008] Also, an attachment portion for attaching the support legs is formed on the attachment plate, and the support legs may be attached to the attachment portion via a leg bracket fixed to the support legs.

Effects of the Invention

[0009] According to the support unit for a top plate of the present invention, the reinforcing beam can be attached to the attachment portion of the attachment plate in an arbitrary direction. More specifically, by making the attachment portion cylindrical, the end portion of the reinforcing beam arc-shaped, and the center attached by a screw, freedom can be given to the attachment position and direction of the reinforcing beam with respect to the attachment plate. As a result, even in the case of a top plate having a planar shape other than a rectangle, the position where the reinforcing beam is attached can be set to a position close to the outer periphery of the top plate that is effective for supporting the top plate.

Mode for Carrying Out the Invention

[0011] Hereinafter, embodiments of the top plate support unit of the present invention will be described with reference to the drawings.

[0012] Figs. 1 to 7 show an embodiment of a furniture with a top plate to which the top plate support unit of the present invention is applied. The support unit 3 of the top plate 1 is for attaching the support legs 2 that support the top plate 1 and for spanning a reinforcing beam 5 between the support legs 2 so as to be attached to the lower surface of the top plate 1. The support unit 3 includes a mounting plate 4 fixed to the top plate 1 for attaching the support legs 2, and a reinforcing beam 5 with both ends 51 attached to adjacent mounting plates 4. The mounting plate 4 is formed with a mounting portion 41 for attaching the reinforcing beam 5, and the reinforcing beam 5 can be attached to the mounting portion 41 of the mounting plate 4 in any direction.

[0013] The mounting plate 4 is formed with a mounting portion 42 for attaching the support legs 2, and the support legs 2 are attached to this mounting portion 42 via a leg bracket 21 fixed to the support legs 2.

[0014] The leg bracket 21 and the mounting plate 4 are made of an alloy such as aluminum, zinc, or magnesium and can be formed by die casting (casting).

[0015] The reinforcing beam 5 is made of sheet metal made of steel (formed by bending or welding a steel material), and a material with a thickness of 1.0 to 3.0 mm, preferably 1.5 to 2.0 mm (1.6 mm in this embodiment) can be used. The length of the reinforcing beam 5 (the distance between the centers of the ends of the reinforcing beam 5 formed in an arc shape) is set according to the design distance between the mounting portions 41 (the centers of the columnar mounting portions 41) of the mounting plate 4.

[0016] Next, the assembly process of the furniture with a top plate applying the support unit 3 of this top plate 1 will be described.

[0017] As shown in FIG. 3, the mounting plate 4 is fixed to a predetermined position of the top plate 1 (in this embodiment, the four corners of the top plate 1 having a trapezoidal planar shape) using screws 61. Screws 61 that are suitable for the material of the top plate 1 are used.

[0018] Next, as shown in FIG. 4, the end of the reinforcing beam 5 is fixed to the mounting portion 41 of the mounting plate 4 using a screw 62. At two locations on the mounting plate 4 (if necessary, it can also be three or more locations), the mounting portion 41 has a cylindrical shape with a recessed center and a female screw formed. The center of the end of the reinforcing beam 5 formed in an arc shape with a screw seat surface at the center is fixed using a screw 62. By doing so, the reinforcing beam 5 can be attached to the mounting portion 41 of the mounting plate 4 in an arbitrary direction (in this embodiment, as shown in FIG. 7, θ1: 55°, θ2: 125°). As a result, the position where the reinforcing beam 5 is attached can be set close to the outer periphery of the top plate 1 that is effective for supporting the top plate 1. A dish bolt can be preferably used for the screw 62.

[0019] Next, as shown in FIGS. 5 to 7, the support leg 2 is fitted to the mounting portion 42 of the mounting plate 4, and the leg bracket 21 fixed to the support leg 2 is also fitted and fixed using a screw 63. A cap bolt can be preferably used for the screw 63.

[0020] According to this top plate support unit 3, the reinforcing beam 5 can be attached to the mounting portion 41 of the mounting plate 4 in an arbitrary direction. More specifically, the mounting portion 41 of the mounting plate 4 has a cylindrical shape, and the end 51 of the reinforcing beam 5 has an arc shape, and the center is attached by a screw 62. By doing so, the mounting position and direction of the reinforcing beam 5 with respect to the mounting plate 4 can have degrees of freedom. As a result, even for a top plate 1 having a planar shape other than a rectangle, the position where the reinforcing beam 5 is attached can be set close to the outer periphery of the top plate 1 that is effective for supporting the top plate 1.

[0021] As described above, the top plate support unit of the present invention has been described based on its embodiments. However, the present invention is not limited to the configurations described in the above embodiments, and its configuration can be appropriately changed without departing from the spirit thereof.

Industrial Applicability

[0022] The top plate support unit of the present invention can provide freedom in the mounting position and direction of the reinforcing beam with respect to the mounting plate. Thus, even for a top plate having a planar shape other than a rectangle, the position where the reinforcing beam is attached can be set close to the outer periphery of the top plate, which is effective for supporting the top plate. Therefore, it can be widely used as a support structure for the top plate of furniture with a top plate such as a desk or a table.
