Abstract

(57) [Summary] [Object] The present invention relates to a wooden staircase constructed to be used for elevating and lowering in a general house, etc., and can reliably prevent stair ringing without causing individual differences among stairmakers and the like. The purpose is to do so. [Structure] Therefore, in a wooden staircase constructed by combining a wooden step board 1 and a wooden embossing board 2,
A spacer 3 made of a plastic material is interposed between an upper edge of the indentation plate 2 and a recess 1a formed in the lower surface of the step plate 1 to fit the upper edge of the indentation plate 2. To do.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wooden stairway constructed to be used for raising and lowering a house or the like.

[0002]

2. Description of the Related Art Conventionally, stairs constructed in a general house have been constructed by combining a wooden step board and a sink board (see, for example, Japanese Utility Model Publication No. 56-8752).

As described above, in the case where the wooden step board and the indentation board are combined with each other, when a load is applied when the stairs are moved up and down, these boards rub against each other to generate stairs.

Therefore, the stairs are prevented from ringing by improving the rigidity of the stairs by modifying the stairs made of wood with specifications such as small plywood sticking specifications and reinforcing metal specifications.

[0005]

However, even if the rigidity of the stairs is increased as described above, the stair ringing occurs when individual stairs are produced due to different tightening of screws depending on the stairs manufacturer. There is.

The present invention is intended to solve such a problem, and provides a wooden staircase capable of reliably preventing the generation of staircase noise without causing individual differences among staircase makers. With the goal.

[0007]

In order to achieve the above object, the wooden staircase of the present invention is characterized in that a spacer made of a non-wood material is interposed between the step plate and the indentation plate.

The non-wood material is a plastic material, and the spacer made of the plastic material is formed on the upper edge of the indentation plate and on the lower surface of the step plate to fit the upper edge of the indentation plate. It may be provided between the recess and the recess.

[0009]

In the above-described wooden stairs of the present invention, since the spacer made of a non-wood material is interposed between the step plate and the indentation plate, the wooden step plate and the indentation plate do not come into direct contact with each other. The stair ringing that was caused by the rubbing of the boards will no longer occur.

When assembling the stairs by fitting the upper edge of the indenting plate into the recess of the step plate, a spacer made of plastic material is inserted between the upper edge of the indenting plate and the recess of the step plate. Only by itself, it can be easily provided between the step plate and the indentation plate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A wooden staircase as an embodiment of the present invention will be described below with reference to the drawings. FIG.
FIG. 2 is a perspective view of the step plate viewed from the lower surface side to show the attachment of the spacer.

In this embodiment, as shown in FIGS. 1 and 2, in order to construct a wooden stair by combining a wooden step board 1 and a wooden step board 2, the upper edge of the step board 2 is changed to a step board. Prior to fitting into the recess 1a formed on the lower surface of the plate 1, a plastic spacer 3 is inserted into the recess 1a along the recess 1a, and the upper edge of the indentation plate 2 is set to the recess 1a of the step plate 1. At the same time when the spacers 3 are fitted in, the spacers 3 are provided between the step plate 1 and the indentation plate 2.

With the above-described structure, since the non-wood material plastic spacer 3 is interposed between the step plate 1 and the indentation plate 2, the wooden step plate 1 and the indentation plate 2 directly contact each other. Even if a large load is applied when the stairs are moved up and down, the plates 1 and 2 do not rub against each other, and the stair ringing as in the conventional case does not occur at all.

Further, since the spacer 3 is merely interposed between the step plate 1 and the indentation plate 2, there is no individual difference between stairs by the stairs maker, and the stairs constructed as in this embodiment can be used. If so, stairs can be reliably prevented.

The present invention is not limited to the above-mentioned embodiments, and is included in the scope of the present invention even if the design is changed without departing from the gist of the present invention. For example, although the non-wooden material spacer 3 made of plastic is used in the above embodiments, the present invention is not limited to this, and may be made of metal, for example. The same effect as can be obtained.

[0016]

As described in detail above, according to the wooden staircase of the present invention, the staircase is manufactured with a very simple structure in which the spacer made of a non-wooden material is interposed between the step plate and the indentation plate. There is an effect that it is possible to reliably prevent the occurrence of staircase noise without causing individual differences among persons.
