Description

[Detailed Description of the Invention] The present invention relates to a staircase in which the bottom of the treads of a house staircase is used as an article storage section.

In an attempt to widen the layered living space inside the house as much as possible, the space directly below the staircase Sasarageta F shown in Figure 1 has already been used as a closet, storage room, etc.; It is difficult to say that the rectangular parallelepiped space, whose two sides are the footboard and the footboard fixed horizontally, has yet been rationally utilized.

According to the Building Standards Act, the height of the tread should be at least 15 cm, and the riser height should be 2.
The size of the rectangular parallelepiped spaces is limited to 5 cm or less, and although the size of the rectangular parallelepiped spaces cannot necessarily be said to be large, their number is equal to the number of stairs, making them a fairly large part as a whole.

In addition, in general life, there are many types of so-called small items, and it is convenient for organizing them to be sorted and stored according to their purpose.

Focusing on this point, the present invention has made the stair treads freely openable and closable so that items can be stored there.More specifically, the treads can be rotated around the rear of the riser at the bottom of the riser. This is a stairway with a storage section where the tread can be freely opened and closed by attaching it freely and locking the front side of the iron plate to a locking piece provided on the upper part of the riser one step below.

As shown in FIG. 1, the stairs are constructed by repeating risers 1 and treads 2 on top of the riser F, and one article storage section S consists of the above-mentioned riser 1, tread 2, and treads above the riser. This space is divided by a back plate 3, a bottom plate 4, and left and right plates (not shown in the figure), which are attached to the front panel.

In many cases, a part of the building frame such as a wall is used as a substitute for the left and right side panels, so in order to standardize the storage section S and supply it as one suitable for mass production, in this invention, the side panels are used instead. Of the four boards, excluding the riser board, back board, and bottom board, three boards are made common, and they are made into rectangular boards of the same thickness and size, and the combination or combination of the four corners, that is, the , Metal molds were used for A, B, B, and C shown by dotted circles.

For the four corners, three types of molding materials are required for the diagonal B-B.
This is because the molding materials at both corners can be the same molding material as shown in the figure.

Now, for convenience, the molding material used for part A will be named assembly member 5, and the molding material used for part B and joining member 6.0 will be named joining member 7, and these will be explained sequentially with reference to FIG.

In the following explanation, we use the words left and right according to the diagram, but in real life, the left corresponds to the side where people go up and down, and the right corresponds to the side where people go up and down, so the left side is the front and the right side is the back. was also used.

Since the combination member 5 used at the A position has the role of protecting the upper end of the riser board 1 and locking the front edge of the tread board 2 constituting the tread, the lower surface 5a is opened downward, In addition, a riser plate insertion groove 5d having a width equal to the thickness of the riser plate 1 is provided,
Further, it is a metal hollow member with a square cross section and a locking piece 5e on the front side of the tread plate is provided on the rear side surface 5b or an extension thereof.

It is preferable that a tapping hole 5f is provided in this hollow portion and a packing groove 5g is provided in the upper surface.

Of course, the upper end of the riser plate is inserted into the insertion groove 5d, and the locking piece 5e shown as an upward hook-shaped body and the packing groove 5g have a packing P for the purpose of cushioning or preventing slipping.
is inserted.

The connecting member 6 used in position B connects the riser plate 1 on the upper side, the tread plate 2 on the left side, the back plate 3 on the lower side, and the bottom plate 4 on the right side. The surface is provided with grooves 6a, 6b, and 6C having a width equal to the thickness of the board to be inserted therein, and the other surface, the left side, is provided with grooves 6a, 6b, and 6C that are integral with the footboard 2 so that the footboard 2 can be opened and closed. It is a hollow metal shape member with a rectangular cross section and is provided with a mounting groove 6d for the tread support piece 8 to be coupled to the tread plate support piece 8.

A tapping hole 6e is provided in this hollow interior.

The mounting groove 6d has a circular cross section as shown in the figure, and the upper left corner thereof is open by about 1 yen, and the mounting type 8a of the tread support piece is formed into a shape that exactly fits into the mounting groove 6d, that is, a circular cross section. The opening range of the above-mentioned circle can be rotated.

In other words, the main connecting member 6 can mount the tread support piece 8 and the rectangular tread plate 2 integrated with the tread support piece 8 at the rear side so as to be rotatable by 90 degrees from horizontal to vertical about the mounting type 8a.

The joining member 7 used in the C position is for fitting the lower edge of the back plate 3 on the top surface and the right side of the bottom plate 4 on the left side. It is a hollow metal mold member having a rectangular cross section and having fitting grooves 7a and 7b having a width equal to , and a tapping hole 7C is provided in the hollow portion.

As already mentioned, since the thickness of the above-mentioned riser plate 1, back plate 3, and bottom plate 4 was standardized for mass production, the insertion grooves 5d, 6a, 6b, and 6c of each member were standardized. , 7a
Both U7b and U7b have the same width.

If the riser board 1 and the back board have the same width (height), the tread surface will not be level, but the width of the bottom board does not have to be the same as the width of the riser board if desired.

However, based on the above-mentioned objective, it is reasonable that all three plates have the same size and thickness.

The figure illustrates this case.

The tread plate is a plate that forms a tread surface, and its usage is not fixed, but an opening/closing plate, so it should be thicker than the other three plates, or it should be decided by considering the appearance of the material.

The assembly of this staircase is clear from what has already been said;
Tapping hole 5f provided in the hollow of each member after sequentially assembling, joining and joining on Sasarageta F
, 6e, and 7C, tapping screws may be screwed into the metal side plate walls (not shown) attached to the body of the detached stairs attachment portion to fix them.

As mentioned above, the invented staircase uses extremely few parts,
This greatly contributes to the effective use of space.
