うねつた形で止められている。 The details of the mounting structure of the elastic belt 1 are shown in FIG. A frame member 2 is provided on the lower surface of the elastic belt 1, and the elastic belt 1 is clamped and attached between the frame member 2 and a fastening fitting 3. Frame member 2
Two protrusions 2A and 2B are formed at a predetermined interval on the flat part of the upper surface, and a protrusion 3A is formed on the flat part of the lower surface of the fastening fitting 3 so as to be located between the protrusions 2A and 2B. It has been done. These convex portions 2A, 2
B and 3A are rods with a circular cross section, and these rods are welded to the upper surface of the frame member 2 and fastened to the fastening fitting 3.
It is welded to the bottom of the. Holes for inserting bolts 4 are formed in the tightening fitting 3, the elastic belt 1, and the frame member 2, and the bolts 4 are inserted into these holes from above the tightening fitting 3 to open the bottom surface of the frame member 2. Tighten with nut 5. As a result, the elastic belt 1 is clamped by the frame member 2 and the fastening fittings 3. When fastening the bolt 4, an elastic cover 6 having a horseshoe-shaped cross section is provided on the fastening fitting 3 so as to surround the head 4A of the bolt 4. A plate 7 and a washer 8 are interposed between the elastic belt 6 and the head 4A of the bolt 4. Also, before fitting the nut 5 into the lower end of the bolt 4, a washer 9 is fitted. A side plate 3B is attached to the side surface of the fastening fitting 3. This side plate 3B also protrudes downward from the lower surface of the fastening metal fitting 3, and forms a convex portion. In this way, the elastic belt 1, which is clamped between the frame member 2 and the fastening fitting 3, is fixed in a wave-like, undulating manner.

用してしつかりと固定されるようになつている。 To explain the entire play equipment based on Figures 2 to 4, the elastic belt 1 has a width of 3 m and a length of 3 m.
15m (straight line distance between both ends after installation), thickness of approximately 1.5cm, and static load of approximately 240Kg/ m2 .
We selected one that would provide a deflection amount of 20 cm or less. As shown in FIG. 3, the surface 1A of the elastic belt 1 is roughened (rough-topped) so that it is hard to slip and has good weather resistance. The roughness of the rough top processing is appropriate to the level of cloth grain. Further, it is desirable that the rubber material used be a rubber that does not easily allow carbon to float and has little deterioration over time. For example, a belt used for a belt conveyor can also be used, and it may be a composite product of rubber and other materials instead of just rubber. The elastic belt 1 can be made of various materials as long as it has a certain amount of deflection, is resilient, and has a certain strength. This elastic belt 1 is supported at a predetermined height from the ground G by a large number of support legs 10. These supporting legs 10... are located at the width ends of the elastic belt 1, and each pair of supporting legs 10 is located at the width end of the elastic belt 1.
They are provided at predetermined intervals in the longitudinal direction. These supporting legs 10... have different heights for each pair (there is no problem even if there are several pairs of the same height), and hold the supporting elastic belt 1 in a undulating shape in its longitudinal direction. It's forcing me. The supporting legs 10 protrude from the ground G by a certain height or more, and a reinforcing member 11 is stretched between the pair of supporting legs 10, 10. Further, when the elastic belt 1 is supported at a predetermined height from the ground G by the supporting legs 10 in a undulating manner, water drainage holes 12 are formed in the troughs of the elastic belt 1. To attach the frame member 2 and the support leg 10, as shown in FIG. 5, the bracket 10A is attached to the support leg 10, the bracket 2C is attached to the frame member 2, and these brackets 10A and 2C are attached rotatably. . As shown in Fig. 2, the base ends of the support legs 10 are secured by digging a hole in the ground G, pouring foundation concrete 13 into the hole, and using anchor bolts 14 to secure the foundation concrete 13. It has become fixed.

It is not necessarily necessary to wave the elastic belt 1.
It may also be a play equipment that is provided flatly at a constant height from the ground G.

may have a shape as shown in FIG.

As explained above, according to the present invention, a frame member attached to the support leg is provided on the lower surface of the elastic belt, the elastic belt is clamped between the frame member and the fastening fitting, and the clamped elastic belt is A convex part is formed on one or both of the fastening metal fittings and the frame member so that the elastic band undulates in a wave shape, or unevenness is formed on the opposing parts of the two parts, so that when the fastening metal fitting is tightened, the convex part becomes the elastic belt. A frictional force is created between the elastic belt and the elastic belt, which is firmly tightened and fixed. The attached elastic belt has enough strength to withstand use even when children play on it, and it is attached and fixed by the frictional force between the elastic belt and the convex part. It is highly durable with less cracking and failure.

There is no fear and it is excellent in terms of safety measures.
