Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the improvement of play equipment suitable for installation in children's playgrounds, parks, field athletic facilities, etc.

[Conventional technology]

Most conventional play equipment installed outdoors is made of logs, metal pipes, or a combination of wood and metal, which are hard and prone to corrosion when exposed to the wind and rain. It was easy to do.

[Problem to be solved]

Conventional play equipment made from hard materials such as wood and metal are susceptible to corrosion, so from a safety standpoint, they not only require repair within a relatively short period of time, but also require frequent maintenance and management. It took a lot of effort for the person involved. Furthermore, most of the conventional play equipment is fixed in both structure and play method, and lacks the degree of freedom that allows children to utilize their ingenuity. Therefore, the present applicant has already applied for a play equipment using an elastic belt. However, the elastic belt installation structure is short and it is impossible to adjust the tension of the belt simply by bolting the elastic belt.If the elastic belt becomes loose due to play or long-term use, it is necessary to adjust the elastic belt tension at any time. It was desired that the belt tension could be adjusted.

SUMMARY OF THE INVENTION An object of the present invention is to provide a play equipment that is structurally flexible, has a large degree of freedom in how to play, and allows the tension of an elastic belt to be easily adjusted.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention provides an elastic belt attachment structure for a play equipment in which a plurality of pairs of left and right legs are provided, a horizontal bar is attached between the pair of left and right legs, and an elastic belt is attached to these horizontal bars. Two or more horizontal bars are attached to the legs to which at least one end of both longitudinal ends of the elastic belt is attached, and the elastic belt is stretched around these horizontal bars in an S-shape, and one end of the elastic belt is waved on the mounting plate. It was installed by undulating the elastic belt into a shape and pinching it with a fastening metal fitting, and the fitting provided on the leg part of the elastic belt whose tension can be adjusted was attached to the mounting plate.

[Effect]

When children play on the elastic belt, the elastic belt bends and rebounds, depending on how they play, the tension on the elastic belt can be loosened or tightened, and even if the elastic belt becomes loose due to long-term use. By adjusting this, the tension of the elastic belt can be set to the desired tension.

〔Example〕

Preferred embodiments of the present invention will be described below based on the drawings.

In Fig. 1, only one of the pair of left and right legs 1, 1 is shown, horizontal bars 2, 2 are attached between the pair of left and right legs 1, 1, and elastic belts 3 are attached to these horizontal bars 2... In this play equipment, at least one end 3A of both ends in the longitudinal direction of the elastic belt 3 is attached to a fixture 4 that can adjust the tension of the elastic belt 3. The base end of the fixture 4 is attached to a bracket 5 suspended between a pair of left and right legs 1, 1. This fixture is a turnbuckle, and consists of a turnbuckle bolt 41 and a turnbuckle body 40, and a mounting plate 42 is fixed to the upper turnbuckle bolt 41. The turnbuckle barrel 40 is covered with a cover 43. This cover 43 is made of a soft urethane foam material covered with a vinyl chloride cover, and has fasteners (not shown) on both sides.
It can be easily attached to the turnbuckle body 40 by closing this fastener. One end 3A of the elastic belt 3 is attached to the mounting plate 42. As shown in FIG. It is attached with bolts 8 and nuts 9.
Two bars 10, 10 are welded and fixed to the base plate 7, and one bar 11 is welded and fixed to the fastening fitting 6.
1, one end 3A of the elastic belt 3 is held between the fastening metal fitting 6 and the base plate 7 so as to undulate in a wave shape. The head 8 of the bolt 8 is on the tightening fitting 6.
A rubber cover 12 with a horseshoe-shaped cross section surrounds A.
A plate 13 and a washer 14 are provided, and the bolt 8 is provided with a washer 14, a plate 13, and a washer 14.
The rubber cover 12, the tightening fitting 6, one end 3A of the elastic belt 3, the base plate 7, and the mounting plate 42 are sequentially inserted, and the washer 15 is inserted into the tip of the bolt 8 protruding from the mounting plate 42, and then the nut 9 is tightened. There is. In addition, a side plate 6A is provided on the side of the tightening fitting 6.
is installed. This side plate 6A also has a shape protruding downward from the lower surface of the fastening metal fitting 6.
A is clamping one end of the elastic belt 3. In this manner, the one end 3A of the elastic belt 3 is pinched between the fastening metal fitting 6 and the base plate 7 in a wave-like wavy shape, thereby eliminating the possibility that the elastic belt 3 will come off.

A plurality of fixtures 4 are attached along the width direction of one end of the elastic belt 3 (see FIG. 4).

As shown in FIG. 5, the other end 3B of the elastic belt 3 may be fastened simply by using a fastening metal fitting 6 without using the fitting 4, or by simply using a fastening metal fitting 6 as shown in FIG. It is also possible to use a conventional mounting method.

A plurality of left and right pairs of legs 1, 1 are provided, horizontal bars 2 of the left and right pairs of legs 1, 1 are attached, and these horizontal bars 2 are attached.
The play equipment to which the elastic belt 3 is attached may be configured as a climbing platform for climbing onto the swing gym 20, as shown in FIG. 6, for example. This climbing platform has four pairs of legs 1, 1 whose base ends are buried in the ground, an arch member 21 is attached between the upper ends of these legs 1, and a rope 22 is installed between these arch members 21. Put it on. The elastic belt 3 used here is attached to the horizontal bars 2 . The thickness of the elastic belt 3 is about 15 mm and the width is 1 m.
A length of approximately 1.5 m and a length of 3 m to 6 m is optimal, and the surface of the elastic belt 3 may be textured (rough top processing) to prevent slipping when walking. This elastic belt 3 can be used not only as a climbing platform, but also as a slide, or for playing by jumping on this elastic belt.

〔effect〕

As explained above, according to the present invention, a plurality of pairs of left and right legs are provided, horizontal bars are attached between the left and right pairs of legs, and elastic belts are attached to these horizontal bars. Two or more horizontal bars are attached to the legs to which at least one end of both longitudinal ends of the elastic belt is attached, and the elastic belt is passed around these horizontal bars in an S-shape, and one end of the elastic belt is waved on the mounting plate. It is installed by undulating it into a shape and pinching it with a tightening metal fitting, and the mounting plate is attached to the mounting plate, which is attached to the legs that can adjust the tension of the elastic belt, so children can ride on the elastic belt and play with it. When the tension is loosened by repeating the action of bending and rebounding, the tension can be easily corrected by adjusting the fixture. Furthermore, it becomes easy to change the tension of the elastic belt depending on the way the player plays. Further, the present invention is useful as a play toy that is highly flexible, highly safe, has improved durability, and has a high degree of freedom. Furthermore, one end of the elastic belt that is attached to the fixture is stretched around two or more horizontal bars in an S-shape, and the other end is also attached to the mounting plate by undulating it in a wave shape and pinching it with a tightening metal fitting. The belt is less likely to loosen, and the attachment strength at one end is high.
