Description

  The present invention eliminates the need for attaching a non-slip as a separate part, can obtain sufficient frictional resistance for anti-slip, can bring out the texture of wood, and can be easily assembled and manufactured at low cost. It relates to the tread board.

A conventional stair tread has the following structure.
It is constructed by smoothing the surface of the stair tread and painting it.
However, it looks good and looks beautiful, but it is very slippery and has a safety problem, such as the need to attach a slip stopper later.
In addition, because of the smoothness, the texture of the wood was impaired, and the appearance of a timber cut was exhibited.

In order to solve this point, the one disclosed in Patent Document 1 has been proposed.
Patent Document 1 states that “it is composed of a stair tread body, a surface plate, and unevenness, and the stair tread body is composed of a single plate obtained by slicing wood such as larch at a predetermined thickness and laminated. The surface board is composed of a single board thinly sliced from hardwood, etc., and is attached to the surface of the main body of the staircase, and the unevenness is raised in a state where thorns due to wood chips are not generated on the surface board The staircase tread that is composed of concave and convex parts formed by the grain of wood and is colored and painted is described, and "the stair tread body is low-cost wood such as larch" The sliced veneer is laminated with an adhesive and pressed to form a plate with an appropriate thickness.The surface plate is composed of a veneer thinly sliced veneer and the surface of the staircase tread body. Pasted in a pressed state, Recess the faceplate in unevenness which is Ukidasa by rough machining of a metal brush, projections, after drying impregnated with sanding sealer, treadle stairs are cutting and polishing a resin brush "is described.
It is recognized by those skilled in the art that the technical meaning of “slicing thinly” is 0.19 to 0.2 mm.
Registered Utility Model No. 3084428

As described above, the step board of the prior art staircase is very slippery and has a safety problem such as the need to attach a slip stopper later, and the texture of the wood is impaired because it is formed smoothly. There was a problem.
In addition, as described above, in the device described in Patent Document 1, the surface plate is composed of a single plate obtained by thinly slicing hardwood or the like. It is recognized that it is 0.19 to 0.2 mm, and 0.19 to 0.2 mm is sufficiently thick because the surface plate is thin, so the difference in unevenness formed by the grain raised by brushing cannot be taken large enough. It was difficult to obtain frictional resistance. Therefore, there is a problem that sufficient safety cannot be ensured.

  In view of the above situation, the present invention does not require a slip stopper as a separate part, can provide sufficient frictional resistance for slip prevention, and can sufficiently bring out the texture of wood, and An object of the present invention is to provide a stair tread that is easy to assemble and can be manufactured at low cost.

In order to solve the above problems, the present invention provides the following configurations.
The invention according to claim 1 is a stair tread composed of a tread body and a surface board adhered to the surface of the tread body, the tread body slicing wood such as larch with a predetermined thickness Consists of laminated plates with laminated single plates, and the surface plate is composed of a single plate obtained by slicing hardwood, etc. with a thickness ranging from 0.6 to 1.0 mm, and irregularities are formed on the surface of the surface plate The unevenness is composed of concave and convex parts formed by the grain that is raised in a state where no thorn due to wood chips or the like is generated on the surface plate, and is colored and painted. It provides a characteristic stair tread.

  In the invention according to claim 2, the surface plate is stuck in a pressed state on the surface of the tread body, and the unevenness of the surface plate is raised along the grain by roughing the surface of the surface plate with a metal brush. The stair tread according to claim 1, wherein the concave and convex portions are impregnated with a sanding sealer and dried and then cut and polished with a resin brush.

  The invention according to claim 3 provides the step board of the staircase according to claim 1 or 2, wherein the surface plate is formed of a single plate that is thickly sliced in a range of 0.60 to 0.70 mm. .

Since this invention is comprised as mentioned above, there exists an effect described below.
The effects of the invention according to claim 1 of the present invention are as follows.
(1) Since the difference in unevenness on the surface can be obtained greatly, the back of the foot (the surface in contact with the tread) is moderately gripped by the unevenness on the surface of the tread due to the user's own weight, so that the tread is less slippery than the conventional example Can be provided. That is, the step board of the conventional example needs to be attached with a non-slip on the front side of the footrest because the surface is slippery, but according to the present invention, it generates a frictional resistance about three times that of the conventional example. As a result, it is possible to ascend and descend the stairs and ensure safety.
In addition, since the frictional resistance is further increased as compared with the device described in Patent Document 1, safety can be further improved.
By using a thick sliced single plate, that is, a relatively thick surface plate, the strength and durability of the surface plate can be improved.
(2) When natural light or the like is applied to the surface, it is possible to draw out a woody texture that was originally only possible with solid wood due to the shading of light due to the unevenness of the grain. In other words, in the current situation where woody dwellings are being reviewed, it can be used as a stepping board with a feeling of material, and the naturalness of the material is conveyed to the touch, which can be used with peace of mind by elderly people in particular.
Moreover, the shadow of the light by the unevenness | corrugation of a grain is clear rather than the idea of patent document 1, and it can draw out a woody material feeling further.
And, it can be used as a substitute for solid wood because it can bring out the texture of wood, and as a result, it reduces consumption of valuable wood resources by reducing the use of solid wood.
(3) In addition, there are effects such as being inexpensive to manufacture, being easy to assemble because of the small number of parts, and being economical.
(4) Furthermore, if the number of stacked tread bodies is reduced and a thin stair tread is used, it can be easily retrofitted to an existing stair and can be reformed inexpensively without the need for extensive repair work. .

  According to the invention of claim 2, in addition to the effect of the invention of claim 1, the difference in unevenness is large, the touch is very good, it is hard to slip, and the natural material feeling can be fully drawn out. The surface of the stair tread with the advantages can be easily formed.

  According to the invention described in claim 3, in addition to the effect of the invention described in claim 1 or 2, by reducing the upper limit of the range of the thickness of the surface plate, the workability is good and the table of optimum economical thickness is obtained. A face plate can be secured.

Hereinafter, embodiments of the present invention will be described with reference to the drawings showing examples.
In FIG. 1, reference numeral 1 denotes a step board of a staircase according to the present invention, and the step board 1 of the staircase is composed of a tread board body 2 and a surface board 3 adhered to the surface of the tread board body 2.

The tread board body 2 is composed of a laminated board obtained by laminating and adhering single boards 2A, 2A,... Sliced low-cost wood such as larch at a predetermined thickness.
The surface plate 3 is composed of a single plate obtained by slicing hardwood and the like in a thickness range of 0.6 to 1.0 mm, and the surface plate 3 has uneven portions 4 formed on the surface. 3 is composed of a concave portion 4A1 and a convex portion 4B1 formed by a grain raised in a state where no thorn due to a wood chip or the like is generated, and is colored and painted.
In addition, “thickly slice in a thickness range of 0.6 to 1.0 mm” means “select a desired thickness in the range of 0.6 to 1.0 mm and slice relatively thickly”. .

  Specifically, as shown in FIG. 2, first, the surface plate 3 is stuck to the surface of the tread board body 2 in a pressed state, and as shown in FIG. 3, the surface of the stuck surface plate 3 is attached to the metal brush. As shown in FIG. 4, the recesses 4 </ b> A and the projections 4 </ b> B are raised along the grain of the surface plate 3, and the spray gun 6 is applied to the raised recesses 4 </ b> A and projections 4 </ b> B. The sanding sealer 7 was applied, impregnated, and dried, and then cut and polished with a resin brush 8 as shown in FIG. 5, and then colored and painted (not shown). It is.

  FIG. 6 shows a state after roughing the surface of the surface plate 3 with the metal brush 5, and the concave portions 4 </ b> A and the convex portions 4 </ b> B that are roughed and raised by the metal brush 5 are not cut off by wood fibers. In addition, wood chips and the like appear, so that thorns 4C, 4C,... Are generated, and the surface feel is poor.

FIG. 7 shows a state after the sanding sealer 7 is impregnated and dried in the concave portions 4A and the convex portions 4B raised by the metal brush 5 described above, and then cut and polished by the resin brush 8, and the thorn 4C, The concave portions 4A1 and the convex portions 4B1 from which 4C... Are removed are formed.
In this state, the touch of the surface is good, the appearance is excellent, and it is possible to bring out a wooden texture.

As described above, the surface plate 3 is sliced with a thickness in the range of 0.6 to 1.0 mm, and the above range is the surface plate 3 suitable for forming the unevenness 4 having an appropriate height. The thickness is defined, and is formed to have a relatively larger thickness than the “thin slice” thickness that is recognized as 0.19 to 0.2 mm by those skilled in the art.
When the thickness of the surface plate 3 is less than 0.6 mm, the unevenness 4 having an appropriate height as the object of the present invention cannot be formed, that is, a suitable frictional resistance cannot be obtained, and the thickness of the surface plate 3 is not obtained. If the thickness exceeds 1.0 mm, the cost of the surface plate 3 may increase, and problems such as an increase in the weight and rigidity of the surface plate 3 and poor workability may occur.
The height of the unevenness 4 is within the range of 0.6 to 1.0 mm of the thickness of the surface plate 3, and the surface plate left after the roughing has a thickness with an appropriate strength, and the unevenness 4 Is appropriately set so as to satisfy the conditions such as the appearance, the performance such as the frictional resistance, and the optimum height excellent in the strength.

  The surface plate 3 is more preferably sliced with a thickness in the range of 0.60 to 0.70 mm. When the thickness of the surface plate 3 is sliced in the range of 0.60 to 0.70 mm, that is, by reducing the upper limit of the range of the thickness of the surface plate 3, the appearance and the friction resistance are excellent, and the work It is possible to secure a surface plate with good thickness and economical optimum.

  The unevenness 4 of the surface plate 3 of the present invention has a greater difference in unevenness than the idea described in Patent Document 1, the unevenness appears clearly, it is difficult to slip, and the natural texture can be fully extracted, The touch is good.
