Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for easily forming a slope on a stairway portion of a building entrance.

[0002]

2. Description of the Related Art In a public facility such as a gymnasium or an auditorium of a school designated as a polling place in an election, for example, in general, several steps are usually formed at the entrance or its entrance.
If there is such a step, for example, an elderly person or a person in a wheelchair cannot enter the building without the help of people. For this reason, a simple slope device for forming a gentle slope on the step is attached at the time of voting in an election.

In the conventional simple slope device, a wooden square member and a plate member are cut into a predetermined size and nailed or the like to finish the side surface shape having a slope S on the upper surface as shown in FIG.

[0004]

However, in this device, when the cross-sectional dimension of the stairway portion K at the entrance and exit is measured in advance and the device is manufactured in the factory based on this, the device is heavy and bulky, which makes transportation difficult. . In addition, at the time of site installation, it is necessary to cut the front portion A and the lower end portion B on the spot according to the fine irregularities of the ground and the tread of the stairs.
The same cutting or cutting adjustment work is required when manufacturing parts at the factory and assembling them on site.

Further, this device lacks versatility because it is manufactured according to the situation of the installation site. In addition, since it requires a large storage space when assembled, it is actually manufactured and discarded each time it is used, which in the long run increases costs and wastes resources.

An object of the present invention is to provide a lightweight and simple slope device which can be easily assembled on site in view of the above problems of the prior art. Another object of the present invention is to provide a simple slope device that can be easily disassembled on site and is easy to store. Further, it is an object of the present invention to provide a simple slope device whose length can be easily adjusted according to the situation at the site.

[0007]

A simple slope device of the present invention comprises a bottom frame formed by a rod-shaped member such as a pipe,
A side frame formed by the rod-shaped member and detachably attached to a side end of the bottom frame, and a plate-like slope body detachably attached to the bottom frame or the lower side frame so as to cover the upper surface of the bottom frame. The bottom frame is characterized in that legs having adjustable lengths are provided at least at both ends of the front part and both ends of the middle part.

In this simple slope device, a skirt plate having continuous slopes may be attached to the rear end of the slope body. The hem plate is made of a thin plate material, and the front end upper surface is substantially flush with the rear end upper surface of the slope main body, while the rear end is grounded during use so that both sides of the front part can be attached to and detached from both sides of the rear part of the bottom frame. It is fixed freely. Alternatively, a reinforcing aggregate formed of a pipe may be attached to the back surface of the slope body, and the aggregate may be detachably fitted to a clip member fixed to the bottom frame.

Further, the above-mentioned bottom frame and side frames are formed by joining pipes by joining members, and standing portions are provided on both sides of the rear portion of the bottom plate, and the lower ends of the side frames are connected to the standing portions and the legs described above. It may be detachably fitted to the upper end of the.

[0010]

This simple slope device is composed of a bottom frame, both side frames and a slope main body, and can be disassembled and assembled by the three parties, so it is easy to transport and does not take up much space for storage. Also,
Since the bottom frame and the both side frames are formed by the rod-shaped members, the weight is lighter than that of the whole formed by the plate material.

Since the bottom plate has legs whose length can be adjusted, a stable slope is formed on the stairs by simply adjusting the length of the legs according to the unevenness of the stair tread or the ground contact surface. The step due to the bottom frame and the thickness of the slope main body at the ground contact portion at the rear end of the slope main body is corrected by attaching a hem piece to the rear end of the slope main body so that the wheel of the wheelchair does not hinder the ride. Both sides of the frame also serve as handrails for slope users.

The side rods 11 and 11 located on both sides of the bottom frame 1 are formed by vertically bundling two pipes, respectively, and regulate both side ends of the slope body 3. Reference numeral 12 is a vertical rod for reinforcement arranged between the side rods 11, 11, 13 is a front horizontal rod, 14 is a horizontal rod in the longitudinal direction, which is slightly intermediate from the front portion, and 15 is a rear horizontal rod. Yes,
These side rods 11, vertical rods 12, and each horizontal rod 13 days 5
Is assembled into a predetermined shape by an appropriate joining member 4, for example, a synthetic resin clip in which a fitting groove or a tubular portion is combined into a T shape or an L shape.

Legs 16 formed of pipe material are attached to both ends of the front side horizontal rod 13 and the intermediate side rod 14. An adjuster 16a for adjusting the length is screwed into the lower end of each of the legs 16 so that the height of the front portion and the intermediate portion of the bottom frame 1 can be adjusted. The rear horizontal rod 15 has standing portions 15a at both ends of which the open ends of the pipes face upward.

Like the bottom frame 1, the side frames 2 and 2 are assembled so that they can be disassembled by joining pipe members with the above-mentioned joining member 4. Reference numerals 21, 22, and 23 are support rods extending vertically, and are provided at a front portion corresponding to each of the horizontal rods 13 to 15 of the bottom frame 1, an intermediate portion slightly closer to the front portion, and a rear portion. At the lower ends of these support rods 21 to 23, the upper ends of the legs 16 of the front horizontal rods 13, the upper ends of the legs 16 of the intermediate horizontal rods 14,
