Description

[Detailed explanation of the idea] This idea concerns stairs.

As shown in Fig. 1, conventional stairs include those in which a support 2 is fixed to a side ledge 1, and a tread 3 is mounted on this support 2, or a second staircase.
As shown in FIG.
Protruding holding parts 4a and 4a' are provided at the upper end, and one end of the footboards 5 and 5' is mounted on these holding parts 4a and 4a', and a recessed board is provided between the upper and lower footboards 5 and 5'. 6,
6' are connected.

However, these stairs all have treads of 3 and 5.5.
' are fixed because these treads 3,5.5'
The disadvantage was that the space underneath could not be used effectively.

Therefore, a staircase was proposed in which the treads were rotatable and a storage space was provided in the tread base.

That is, as shown in FIGS. 4 and 5, this staircase is constructed by fixing a back plate 8 between a pair of side beams 7 (one not shown), and attaching the back plate 8 vertically to the L-shaped member 9 shown in FIG. Both sides of the piece 9a (i.e., the recessed board part) are each pivotally connected to a pair of side protrusions 7, and a support 10 for horizontally mounting and supporting the horizontal part 9b (i.e., the footboard part) of this L-shaped member 9 is mounted on the side. 7, and the side and rear end surfaces of the bottom plate 11 are fixed to the sidewalls 7 and back plate 8, respectively, and the front end surface 11a of the bottom plate 11 is disposed near the lower end of the vertical piece 9a of the L-shaped member 9.

In this case, the L-shaped material 9 is made by stacking a plurality of wooden veneers coated with adhesive on the surface, and heating and pressing them with a mold (not shown) to form each wooden veneer into an L-shape. It is formed by bending and laminating and bonding.

In addition, pins are inserted (L
12, and by inserting a support pin (not shown) protruding from the inner surface of the side wall 7 into the pin insertion hole 12, the L-shaped member 9 can be rotatably attached to the side wall 7. There is.

The bottom plate 11 is fixed at its rear end by a mounting bracket 13 attached to the upper surface of the back plate 8, and is mounted and held by a support 14 fixed to the inner surface of the sidewall 7 at its front end.

Note that the bottom plate 11 and the side beams 7 are made of synthetic material, wood, or the like.

In this way, the staircase of this proposed example has a
A storage space 15 surrounded by the side beams 7, the back plate 8, the bottom plate 11 and the L-shaped member 9 is formed.

When storing in the storage space 17, the L-shaped member 9 is lifted and rotated clockwise around the pin insertion hole 12, as shown by the imaginary line in FIG.

In addition, normally, the horizontal piece 9b of the L-shaped member 9 is mounted on the holder 10, and the vertical piece 9a is used as a support plate, and the horizontal piece 9b is used as a footboard.

However, in the staircase of this proposed example, the inside of the storage space 15 is dark and it is inconvenient to take in and out the stored items.
There was a danger of losing one's footing because it was dark near the area, that is, the area under one's feet.

Therefore, an object of this invention is to provide a staircase which can form a storage space below the tread and can illuminate this storage space and the tread.

An embodiment of this invention will be described with reference to FIGS. 7 and 8.

In other words, in this staircase, the front end 9C' of the tread portion 9b' of the generally shaped member 9' located at the upper stage is projected further forward than the recessed plate portion 9a' of the generally shaped member 9' located at the lower stage. set up,
A lamp 16 is provided on the lower surface of this protruding front end 9C'.

The rest of the configuration is the same as the proposed example shown in Figure 5, so
Identical or equivalent parts will be given the same or equivalent symbols and their explanation will be omitted.

With this configuration, the storage space 15 can be formed below the footboard portion 9b'.

When storing items in the storage space 15, the inside of the storage space 15 can be illuminated with the lamp 16 by rotating the L-shaped member 9' clockwise as shown by the imaginary line in FIG. I can do it.

The same applies when taking out stored items.

On the other hand, during normal times, that is, when the footboard portion 9b' is in a horizontal state, the footboard portion 9b' is illuminated by the lamp 16 to prevent the user from stepping on the stairs.

Furthermore, since the tread plate part of the tread part is integrally formed with the L-shaped member 9' of irregularly shaped laminated wood, there is no need for dovetail joints or nailing to connect the tread plate and the tread plate, which were conventionally done. Workability is greatly improved.

Furthermore, since irregularly shaped laminated wood is used as the L-shaped member 9', the strength is improved and the front edge of the footboard can be bent downward, increasing the degree of freedom in design.

As described above, the staircase of this invention consists of a pair of side beams, a back plate installed between these side beams, and a vertical and horizontal footboard section, respectively, on both sides of the footboard section. a plurality of L-shaped members which are pivotally connected to the pair of side beams and whose front ends of the upper step plate portions protrude forward than the lower step plate portions; a plurality of holders, each of which is fixed to the side beam and holds the footboard portion of the cross section horizontally; Since it is equipped with a plurality of bottom plates whose surfaces are arranged near the lower ends of the recessed plates, a storage space is formed below the treads, and the effect is that this storage space and the treads can be illuminated. has.
