Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an edge structure of a top plate such as a desk.

[0002]

[Prior art]

 In many conventional structures of the top plate edge of a desk or table, one edge member is fixed to the end of the top plate body to form the top plate edge. In this case, the cross-sectional shape of the edging material was limited to a symmetrical shape in the upper and lower directions.

However, in recent years, the shape of the top plate edge has diversified, and its cross-sectional shape is vertically asymmetrical. For example, in order to make the top plate thickness look thin at the edge, the lower half of the top plate edge may be an inclined surface. It came to adopt the shape to do.

In this case, if an attempt is made to form the shape with one edge member, the thickness of the edge member in the horizontal direction becomes large, and the bendable curvature in the horizontal direction becomes large. Therefore, if you try to attach this edge-shaped edge material to the entire circumference of the top plate body, either increase the curvature of the top plate corners, or use edge parts for each side of the top plate body and molded parts for the corners. You will have to use two types of edge material.

In the former case, the planar shape of the top plate is restricted, and in the latter case, there are problems such as many exposed seams of the edge material and poor appearance.

[0006]

[Problems to be solved by the device]

 In view of the above problems of the conventional technique, the present invention can form various edge shapes including an inclined surface and the like without increasing the thickness of the edge material, and the top plate corner portion. The purpose is to provide a well-structured edge structure of the top plate that can reduce the curvature of.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the edge structure of the top plate of the present invention is such that a concave step portion is formed on the end surface of the main body of the top plate, and the concave step portion and the other end surface are formed as separate flexible bodies. The feature is that each edge is fixed.

In this case, it is preferable that a part of the edging material fixed to the recessed stepped portion and a part of the edging material fixed to the end surface other than the recessed stepped portion are polymerized with each other.

[0009]

[Action]

 By attaching separate flexible edging materials to the recessed stepped portion and the other portions on the end surface of the top plate body, the horizontal thickness of each edging material is reduced, and The radius of curvature at the time of bending can be reduced, and various edge shapes including inclined surfaces and the like can be formed with good appearance.

[0010]

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings. (1) is a wooden top plate main body, a concave step portion (3) is formed in the lower half of the front, rear, left and right end surfaces (2), and the middle portion of the concave step portion (3) A slit-shaped recess (5) is cut in the middle portion of the end surface (2) other than the recessed stepped portion (3) (hereinafter referred to as the outer end surface) (4).

In the recessed stepped portion (3), an outer surface (6a) forms an inclined surface that inclines inward and downward, and an inner surface (6b) has a vertical cross-section edge member (6). ) Horizontally extends inward from the middle part of the inner surface (6b) and has two serrated retaining ridges (6c) on the upper and lower surfaces, and insert the insertion piece (6d) It is fixed by being press-fitted into the groove (5).

In addition, the outer end surface (4) has an outer surface (7a) having an arc shape or an elliptical shape with a large curvature, and an inner surface (7b) having a vertical thin horizontal edge. A material (7) extends horizontally inward from the middle part of the inner surface (7b) and has two serrated retaining ridges (7c) on the upper and lower surfaces, which are insert pieces (7d). It is fastened by press-fitting it into the upper groove (5).

Both edge members (6) and (7) are preferably made of a plastic material such as a plastic material such as a soft synthetic resin material that is elastically flexible or an aluminum light alloy.

In the present embodiment, the lower end portion (7e) of the upper edge member (7) is slightly hung from the lower end of the outer end surface (4), and the lower end portion (7e) is referred to as the outer end surface (4). The lower edge member (6) is prevented from coming off by the upper edge member (7) by superimposing it on the outside of the upper part of the outer surface (6a) of the lower edge member (6) so that they are flush with each other. I am doing it.

According to the present invention, as shown in FIG. 2, the curvature of the top plate body (1) at the angle (1a) can be significantly reduced. As described above, this is formed with the recessed stepped portion (3) on the end surface (2) of the top plate body (1), and the edge member (6) fixed to the recessed stepped portion (3) and the recessed stepped portion (3). This is because the thickness in the horizontal direction is reduced by making the rim material (7) fixed to the outer end surface (4) other than the above different from each other.

That is, the end surface of the top plate body (1) is simply a vertical surface without the recessed stepped portion (3) as described above, and is formed by the both edge members (6) and (7) of FIG. If a single edge material (not shown) that forms the same contour line as the contour line is attached, the horizontal thickness of the edge material increases significantly, and even if a flexible material is selected, The bendable curvature in the horizontal direction becomes large, and it becomes extremely difficult to bend and fasten a single edge member to the corner portion (1a) having a small curvature as shown in FIG.

Further, if the edge surface of the top plate main body (1) is covered with a single edge material in this way, the cross-sectional area of the edge material becomes large, and the material cost of the edge material becomes high.

According to the present invention, such a problem can be solved by adopting the above-mentioned configuration. In addition, if necessary, a slit shape or a free edge side may be provided at a portion corresponding to the corner portion (1a) of the top plate body (1) in the insertion pieces (6d) (7d) of the both edge members (6) (7). It is better to form a notch (not shown) such as a wide triangle.

[0019]

[Effect of device]

 According to the present invention, the following effects can be achieved. (a) Since the edge material that is fixed to the recessed stepped portion and the edge material that is fixed to the end surface of the top plate body other than that can be formed separately as thin bodies, each edge material can be formed thinly. Even if the curvature that can be bent in the horizontal direction is small and the curvature of the corners of the top plate body is also small, both edges can be bent along the corners of the top plate body to be fixed. Further, it is not necessary to separately form a rim member for a corner portion, and various top and bottom asymmetrical top plate rim shapes can be formed neatly without exposing a seam or the like to the outside.

(B) By forming a recessed stepped portion in the top plate main body according to the shape of the top plate edge to be formed, the sum of the cross-sectional areas of both edge materials can be set to a single value as in the conventional case. The cross-sectional area of the edge material when the same edge shape is formed only by the edge material can be made significantly smaller, and the material cost of the edge material can be reduced.

(C) By changing the colors of both edge materials, it is possible to easily form a beautiful top plate edge in which the top plate edge is divided into upper and lower colors.
