Description

[Detailed explanation of the idea] The present invention relates to a top plate of a desk or the like.

A protective edge is attached to the circumferential surface of a so-called top plate of a desk, dining table, etc. for the purpose of protection or decoration.

Conventionally, this protective edge has generally been a band-shaped protective edge made of extrusion molding because it can be easily attached and manufactured at low cost.

Therefore, if the environment in which it is used differs, that is, changes in temperature due to climate change, the protective rim may contract or expand.
The abutting portions of the protective edges on the circumferential surface of the top plate separate, creating gaps, or lifting up, resulting in an unsightly appearance.

The present invention improves these shortcomings and provides a top plate for desks, etc., which is easy to manufacture, easy to install, and maintains its aesthetic appearance even under changes in the environment in which it is used. The structure is such that in a top plate of a desk, etc., which has a protective edge made of extruded synthetic resin on its periphery, an engaging part is formed on the top part, and the top part is bent downward into an L-shape and engaged with the side part. A frame having a substantially U-shaped cross section formed with a section is fixed to the lower surface of the end of the main body of the top plate to form a gap between the main body of the top plate and the above-mentioned engaging part, and has a fitting protrusion on the upper side. A protrusion is formed at the tip of the fitting protrusion, and a protective edge with a locking protrusion formed below is inserted into the above-mentioned gap, and the protrusion, the retaining part, and the locking protrusion are connected to each other. It is characterized in that a raised protrusion is provided on one side of the mating protrusion by raising it up on one side of the mating protrusion, and is provided facing the retaining part where the abutting part of the protective edge is located while engaging the protrusion with the retaining part. It is.

The present invention will be explained below with reference to the drawings.

FIG. 1 shows a perspective view of the entire top plate equipped with the present invention;
1 is a top plate, 2 is a protective edge, and 3 is a butt portion of the protective edge 2.

The top plate 1 includes a back plate 12, a plate-shaped top plate main body 11 made of decorative plywood 13 that is slightly larger than the back plate 12 attached to the upper surface of the back plate 12, and frames 14 provided on the lower surface of the four corners of the top plate main body 11. The frame 14 consists of a top plate reinforcement 15 attached at a predetermined position excluding the abutment part 3 between both longitudinal ends of the top plate main body 11 and the protective edge 2, and the frame 14 is formed by bending the top part 141 downward and further upward in an L shape. The engagement portion 142 and the step portion 143 are formed by bending the step portion 143 to form a gap 140 on the lower surface of the periphery of the top plate main body 11. Section 144
, forming a locking portion 145.

The engaging portion 142 has two U-shaped notches 146 that face each other with the abutting portion 3 in between, in the vicinity of the abutting portion 3 of the protective edge 2, and are raised in the direction of the abutting portion 3 of the mating protrusion 23. A cut-and-raised protrusion 147 is formed.

The top plate reinforcement 15 has a rising part 152, where the locking part 145 is located, at the rear end of the mounting part 151 that is bent downward into an L-shape, and the rising part 152 is further bent upward into an L-shape. Then, the locking portion 145 and the side surface portion 1
44. It is composed of a top plate reinforcing side portion 153 that protrudes from the inner surface of the top plate.

The protective edge 2 is made of synthetic resin and has a vertically elongated cross section, and has a stainless steel foil 22 on the upper surface of the top 21 and grooves 20 that are inclined so that the inner side becomes narrower on the lower part of the inner surface of the top 21. The fitting protrusion 23 has a protrusion 24' that protrudes downward at the end thereof, and has a side portion 24 continuous to the top portion 21, with the lower end of the side portion 24 protruding inward. At least it constitutes a lower protective edge 26 having a locking protrusion 25 at its tip.

A metal foil 27 such as aluminum foil is provided within the side portion 24 over the entire width of the protective edge 2.

The stainless steel foil 22 and the metal foil 27 are molded at the same time when the protective edge 2 is manufactured by extrusion molding of synthetic resin.

The protective edge 2 constructed as described above is attached to the circumferential surface of the top plate 1 in the following manner.

The fitting protrusion 23 of the protective edge 2 is fitted into the gap 140 formed on the lower peripheral surface of the top plate main body 11, and the protrusion 24 is engaged with the engagement part 142.

Then, the peripheral end surface of the top plate main body 11 is connected to the groove 22 of the protective edge 2.
The top part 21 is made to protrude above the periphery of the main body 11 of the top plate.

Next, the lower part of the protective edge 2 is pushed inward, the locking protrusion 25 is locked with the locking part 145 of the frame 14, and it is sequentially attached around the top plate, and finally, the ends of the protective edge 2 are butted together. Form part 3.

After that, turn the top plate 1 face down, and use a screwdriver or the like to raise the cut and raised protrusion 147 of the frame 14 toward the top plate main body 11 side in the direction of the abutting portion 3, and insert it into the fitting protrusion 23 of the protective edge 2. .

As described above, in the present invention, the cut-and-raised protrusion provided on the frame at the abutting part of the protective edge is raised in the direction of the abutting part and embedded in the mating protrusion, so that the end surfaces of the protective edge are in close contact with each other. However, it is possible to suppress the shrinkage and expansion of the protective edge due to temperature changes of the outer ring as much as possible, and prevent the butt part of the protective edge from separating and lifting up, which will spoil the aesthetic appearance of the top plate of a desk, etc. This is a useful device that can be maintained in good condition without any problems.
