Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a device for firmly and aesthetically connecting a pair of orthogonal plates, such as a top plate and a side plate of furniture, for example.

[Conventional technology]

In furniture, etc., the ends of two plates are often connected at right angles to each other.

Figure 4 shows an example of a conventional orthogonal section.
The upper end surface of the vertical side plate 52 overlaps the back end of the horizontal top plate 51 and is connected to the angle-shaped connecting fitting 53 and screws 54.

Reference numerals 55 and 56 denote decorative boards that are attached to the surfaces of both boards 51 and 52, respectively, and 57 is a decorative board that is attached after both boards 51 and 52 are connected in order to cover the unsightly end of the top board 51.

FIG. 5 shows another example of the conventional orthogonal part, in which the back edges of the top plate 71 and side plate 72 are butted against each other, and are connected with the connecting fittings 73 and screws 74 as described above, and further, both A flexible decorative edge material 75 made of synthetic resin or the like is fitted into the stepped portion formed by the end surfaces of the plates 71 and 72, and the protrusion 7 is connected to the edge material 75.
6 is in the cut groove 77 cut into the end surface of the top plate 71,
It is clamped to prevent it from falling out.

78 and 79 are decorative boards similar to 55 and 56 above.

[Problem that the invention attempts to solve]

Since the orthogonal parts shown in FIG.
5, 57 may peel off.

In the orthogonal part shown in FIG. 5, the top plate 71 does not rest on the side plates 72, so the strength is weak against the load that the top plate 71 receives from above, and there is also a cut groove 77 for attaching the edge material 75. , it is necessary to cut with high precision, and processing requires skill.

Furthermore, a rim material 75 covering the end surfaces of both plates 71 and 72 is provided.
Not only is it difficult to visually harmonize with both decorative boards 78 and 79, but also when the edge of the top plate 71 is made into an arc shape, it is difficult to curve it along the edge. If the edge material 75 is forcibly bent, wrinkles may form in the radial direction on both the upper and lower sides of the edge material 75, and both plates 7
A gap may be formed between the end faces of 1 and 72.

[Means for solving problems]

The present invention involves cutting a step-shaped notch in the back end of one plate, which is parallel to both the front and back sides, and whose width is narrower than the thickness of the other plate. , a step-shaped notch in which the width of the notch surface that is parallel to both the front and back surfaces is narrower than the thickness of one of the plate materials, and the width of the notch surface that is perpendicular to both the front and back surfaces is slightly wider than the width of the above-mentioned notch surface of one of the plate materials. Cut out, fit both notches together, and properly fix both plates at right angles.
Furthermore, a flexible decorative edging material is fitted into the stepped portion formed by the end surfaces of both plate materials, and a protrusion continuous to the decorative edging material is connected to the end surface of one plate material and the cutout surface of the other plate material. The above-mentioned problem is solved by sandwiching the material in the gap formed between them so as not to come off.

[Effect]

In the device of the present invention, the notches at the ends of the top plate and the side plates that are perpendicular to each other are engaged with each other, so that the apparatus is strong against loads from above and from the outside.

In addition, since the edge material provided at the corner can be made thinner, there is less discomfort, and even if the top plate is fan-shaped or circular, it can be curved easily along the edge of the top plate.

〔Example〕

Figures 1 and 2 show an example of the device of the present invention, in which 1 is a top plate, 2 is a decorative plate thereof, 3 is a side plate, and 4 is a top plate.
is its decorative board.

A step-shaped notch 5 is cut at the end of the back surface of the top plate 1, and a notch surface 5a parallel to the top plate 1 is set to be narrower than the thickness of the side plate 3.

A step-like notch 6 is also cut in the back end of the side plate 3, and the notch surface 6a parallel to the side plate 3 is narrower than the thickness of the top plate 1 and is perpendicular to the side plate 3.
b is set to be slightly larger than the cutout surface 5a.

Both plates 1 and 3 have their notches 5 and 6 engaged with each other, and their back surfaces are connected by an angle-shaped connecting fitting 7 and screws 8.

Step portion 9 formed by end surfaces 1a and 3a of both plates 1 and 3
A flexible decorative edging material 10 made of synthetic resin having a fan-shaped cross section is fitted into the edging material 10, and a protrusion 11 connected downwardly to the inner end of the edging material 10 is inserted between the end surface 1a and the cutout surface 6a. It is held in a downwardly facing gap 12 formed in the gap 12 so as not to come off.

The edge material 10 has its protrusions 11 secured in advance to the end surface 1a of the top plate 1 with pins 13, and then both plates 1,
2 are connected and attached.

Since the decorative edge material 10 used in the device of the present invention is thin, even if the top plate 1 is fan-shaped as shown in FIG. 2, it can be easily curved and attached along the end surface 1a of the top plate 1.

FIG. 3 shows another example of the device of the present invention,
Reference numerals 31 and 32 indicate a top plate and its decorative panel corresponding to 1 and 2 above, respectively, and 33 and 34 indicate a side panel and its decorative panel corresponding to 3 and 4 above, respectively.

Notches 35 and 36 corresponding to the above-mentioned 5 and 6 are cut in the back ends of both plates 31 and 33, respectively.The notches 36 in this embodiment have a notch surface 36a parallel to the side plate 33. , the width of the notch 35 is smaller than the thickness of the top plate 31, and the notch 35 has a notch surface 35a parallel to the top plate 31, a width smaller than the thickness of the side plate 33, and a notch surface 35b perpendicular to the top plate 31, the above-mentioned notch surface. 36a is set to be slightly larger than that of 36a.

Therefore, as in the previous embodiment, when the back surfaces of both plates 31 and 33 are connected with the connecting fitting 37 and the screw 38, a gap 39 facing the side is created between the end surface 33a of the side plate 33 and the cutout surface 35a. is formed, and between the end surfaces 31a and 33a of both plates 31 and 33, the above-mentioned
A step portion 40 similar to the above is formed.

Reference numeral 41 is a decorative edge material corresponding to 10 above, and a protrusion 42 that is laterally connected at the inner end has a large number of sideways-facing retaining strips 43 formed thereon, and these retaining strips 43 close the gap. 39 so as not to come off.

This embodiment also has the same functions and effects as the previous embodiment.

[Effect of idea]

In the device of the present invention, the notches at the ends of the two orthogonal plates engage with each other, so both are strong against loads from above and from the outside, and the decorative edges provided at the corners are Because it is thin, it does not look out of place even though it is different from the two boards, so it does not spoil the aesthetic appearance, and even if one of the boards is fan-shaped or circular, it can be curved easily along the edge of the board.
