Description

[Detailed description of the invention] This invention relates to an improvement of a folding slide used indoors, and aims to prevent injuries caused by jamming fingers between the joint ends of the landing board and the sliding board during folding and assembly. The purpose is to

Conventionally, in wooden folding slides, both the sliding board and the landing board are made of hard wood-based materials, so when folding or assembling, if you jam your fingers between the joint ends of the sliding board and the landing board, There was a risk of injury.

This invention aims to improve the above-mentioned drawbacks of the conventional slide and to provide a folding slide that can be folded safely. Therefore, its feature is that the upper end of the sliding board and the landing board are In a folding slide in which the descending side end is refractably joined, a joint plate made of a flexible material is attached to the upper end of the sliding board or the descending end of the landing board to close the gap between the upper end and the descending end. It's at the point where I arrived.

Hereinafter, embodiments of this invention will be described based on the drawings.

In the drawing, 1 is a sliding board, 2 is a landing board, 3 is a step ladder, 4 is a pair of right and left support legs, and 5 is a pair of left and right handrail frames, which are connected to both sides of the upper end 1a of the sliding board 1 and the landing board 2. It is refractably joined to both sides of the lower end 2a of the supporting leg 4 via a connecting bolt 6, and the upper end 4a of the support leg 4 is rotatably inserted and connected to the connecting bolt 6. Both sides of the ascending side end 2b of the landing board 2 and both sides of the upper end of the step ladder 3 are joined via connecting bolts 7 so as to be bendable.

A joint plate 8 made of a flexible material such as soft or semi-hard plastic is attached to the upper end 1a of the sliding plate 1 and extends further upward from the upper end 1a. The gap between the upper end 1a of the sliding board 1 and the downward end 2a of the landing board 2 is closed. In the illustrated example, the joint plate 8 is composed of an upper plate 9 and a lower plate 10 which are integrally formed in a bifold shape. The recesses 11 of the lower plate 10 and the upper plate 9 are directly overlapped, and the bulges 12 of the lower plate 10 and the upper plate 9 are integrally formed through fin-like ribs 13. It exists as a connected structure. This joint plate 8 has the upper end 1a of the sliding plate 1 fitted between the edge 9a of the upper plate 9 and the edge 10a of the lower plate 10,
The end 13a of each fin-like rib 13 is connected to the end surface 1 of the upper end 1a.
b, and the inner wall portion 1 of each recessed portion 11.
It is attached to the upper end 1a of the sliding board 1 by abutting the end face 1a against the same end face 1b and fixing this abutting portion with a fastener 14 such as a staple. The joint plate 8 constructed or attached in this manner exhibits sufficient flexibility at the direct overlap portion between the recessed portion 11 of the lower plate 10 and the upper plate 9, and furthermore, no tread pressure is applied to the joint plate 8. When it is pressed, the end 13a of the fin-like rib 13 strongly contacts the end surface 1b of the sliding board 1, exerting a tensioning action, so that it can sufficiently withstand stepping pressure.

Note that, contrary to the above embodiment, the joint plate 8 may be attached to the downward end 2a of the landing board 2 so as to match the slope of the sliding board 1.

In the assembled state, the above-mentioned slide connects the midway part of the side surface of the sliding board 1 and the midway part of the side surface of the support leg 4 with the bendable joint rod 15 maintaining a straight line, thereby controlling the inclined state of the sliding board 1 and the support leg 4.
maintain vertical state. Further, the inclined state of the step ladder 3 and the horizontal state of the landing board 2 are maintained by connecting the midway portion of the side surface of the step ladder 3 and the midway portion of the side surface of the landing board 2 with the handrail frame 5. The handrail frame 5 is removably attached to the side surface of the step ladder 3 and the side surface of the landing board 2 with mounting bolts 16, respectively.

To fold the slide, remove the mounting bolts 16, remove the handrail frame 5, and attach the step ladder 3 to the connecting bolt 7.
Rotate the step ladder 3 and the landing board 2 in the direction indicated by the arrow A in FIG. Finally, the joint rod 15 is bent into a dogleg shape, and the support leg 4 is rotated around the connecting bolt 6 in the direction of arrow C in the same figure, and placed on the side surface of the sliding plate 1. All you have to do is fold it so that it polymerizes, and the whole can be folded compactly. When assembling, the folding operation described above can be performed in the reverse order.

As mentioned above, the foldable slide of this invention has the upper end 1a of the sliding board 1 or the downward end 2 of the landing board 2.
Since the joint plate 8 made of flexible material is attached to the upper end 1a and the lower end 2a to close the gap between the upper end 1a and the lower end 2a, when folding or assembling this slide as described above, even if , the hand is the descending end 2a of the landing board 2 or the upper end 1a of the sliding board 1.
Even if it is pinched between the joint plate 8 and the joint plate 8, the pinching pressure is relieved by the flexibility of the joint plate 8, so there is no chance of injury, and there is an advantage that it can be folded and assembled very safely.
