Description

  The present invention relates to a connection fitting used for connecting the equipment components of playground equipment, which is a combination of equipment components such as slides, stairs, fence panels, and circular columns.

  In recent years, a plurality of playground equipment such as a slide and a jungle gym has been provided as a single playground equipment facility as a facility for an infant to play outdoors in a park or the like. In this playground equipment, a plurality of playground equipments are not simply connected, but various equipment components such as slide plates of slides, handrails, jungle gym bars, fence panels, wall panels, floor panels, etc. It is designed so that it can be selected and combined according to the desired design, etc., and a circular column that is one of the equipment components and serves as a support member is erected at each preset position, Each playground equipment is configured by combining various equipment components so that the playground equipment portion is supported by the circular support.

In connection with such playground equipment, the present applicant has a connecting bracket having a counterbore so that the head of the mounting bolt does not pop out when assembling equipment components such as a circular support and a fence panel or a wall panel aligned with the support. The device which connects both by using is proposed (refer patent document 1).
Further, in the present applicant, when supporting the equipment constituent members arranged with the circular struts in between, the circular struts are sandwiched between a pair of substantially arc-shaped connecting brackets, An equipment component such as a panel or a wall panel is fastened, and a contrivance for improving safety is proposed as a structure covered with an elastic rubber in the connection fitting (see Patent Document 2).

And in such playground equipment equipment, as mentioned above, it is one of the equipment constituent members, and the former connecting metal fitting for connecting to the fence panel etc. assembled to this circular support and the circular support that serves as a support member. There is also a demand for improving safety by providing a cushioning material.
Therefore, the present invention has an object to increase the cushioning effect for the connection fittings passed to two adjacent equipment components without being limited to both the circular support and the panel to be assembled thereto, and an infant using playground equipment The purpose is to make it possible to play safely.

  The present invention has been made in consideration of the above-described problems, and is a connecting fitting that is passed to adjacent equipment components of a playground equipment that connects a plurality of equipment components, and corresponds to the adjacent equipment components. A mounting body in which the mounting plate is provided with a bolt hole through which a mounting bolt for passing the mounting bolt for fastening the mounting plate to the equipment constituent member is opened. It consists of an elastic rubber cushioning body that covers the surface of the equipment component other than the opposing surface and the surface around the bolt hole on the opposite side of the opposing surface, and covers the bolt hole of the cushioning body. A counterbore part having a depth larger than the head dimension of the mounting bolt to be passed through the bolt hole is provided at each of the positions where the bolt hole is passed, and is flexible on the side along the length direction of the concave groove part between the two counterbore parts. Provided with a flexible wall having Providing connecting fitting for playground equipment and is intended to solve the above problems.

  According to the present invention, the head of the mounting bolt does not protrude from the counterbore portion of the shock absorber even if the connecting bracket is bolted to the equipment component through the mounting bolt through the bolt hole. Because the counterbore part is continuous with the groove part, the counterbore part does not become a deep hole, and even if an infant puts a finger into the counterbore part and touches the head of the mounting bolt, Will not be lost. Furthermore, since a flexible wall with flexibility is provided in the recessed groove portion that continues to the spot facing portion, it can also be buffered by the collapse of the flexible wall, such as outdoor ultraviolet light, heat, rainwater, etc. In consideration of the above, the selection range of the elastic rubber material that does not impair the shock absorbing property is expanded.

Next, the present invention will be described in detail based on the embodiment shown in FIGS.
In the figure, reference numeral 1 denotes a playground equipment equipment fitting, and the playground equipment equipment fitting 1 extends over a circular column 2 of a metal pipe, which is an equipment component of the playground equipment, and a wall panel 3 arranged in parallel to the circular column 2. As shown in FIG. 1, it is used for assembling and supporting the wall panel 3 arranged along the radial direction of the circular column 2 on the circular column 2.
In this play equipment fitting 1, a shock absorber 5 made of elastic rubber is integrated with the metal body 4 by an insert molding method in which a metal metal body 4 is placed in a molding die (see FIG. 5). First, as shown in FIG. 4, the metal fitting body 4 is curved in accordance with the outer peripheral surface shape of the circular support column 2 and the radial direction of the circular support column 2 from the end of the mounting plate part 6. A rib that keeps the strength of the bent portion at the bent portion between the two mounting plate portions 6 and 7 and the other mounting plate portion 7 that is formed in a flat plate shape so as to correspond to the wall panel 3. 8 is integrally provided, and a bolt hole 9 is formed in each of the mounting plate portions 6 and 7 through which a mounting bolt that is fastened to the circular column 2 or the wall panel 3 is passed.

As shown in the cross section of FIG. 5, the shock absorber 5 includes opposing surfaces 6 a and 7 a on the equipment component side of the mounting plate portions 6 and 7 in the metal fitting body 4 and bolts on the opposite side to the opposing surfaces 6 a and 7 a. Covers the surface excluding the hole periphery in close contact with difficulty. Further, a counterbore 10 is provided at a position corresponding to the bolt hole 9 of the shock absorber 5 as a recess which is an internal space in which the head a of the mounting bolt can be placed. Each of the spot facings 10 has a depth that is larger than the head dimension (height dimension) of the mounting bolt, and the connection fitting 1 is bolted to the equipment component (such as the above-mentioned circular column or wall panel) with the mounting bolt. Sometimes it is provided so that the head of the mounting bolt does not protrude (see FIG. 1).
As shown in FIGS. 2 and 3, the two counterbore portions 10 are continuous with the concave groove portion 11 extending between the two counterbore portions 10, and each of the counterbore portions 10 is a deep circular hole. Instead, it is formed in a shape having an outward spread. Furthermore, in this embodiment, the two counterbore portions 10 and the concave groove portion 11 are integrated to form the shock absorber 5 having one concave portion.

  In the shock absorber 5 in the play equipment fitting 1, a flexible wall 12 having flexibility is provided on each side along the length direction of the groove 11 as shown in FIG. 5. The cage. When another object such as an infant's hand hits the flexible wall 12, the flexible wall 12 is deformed to absorb the impact, and the buffer effect due to the elastic deformation of the elastic rubber itself of the buffer body 5 A buffering effect due to the shape deformation of the flexible wall 12 is added to provide a high buffering property.

  As an example, stainless steel SUS304 is preferably used for the metal fitting body. Moreover, it is good to employ | adopt ethylene-propylene-diene rubber (EPDM) as an example of the elastic rubber which forms a buffer, and it has a mechanical resistance and a chemical resistance while having a weather resistance and a sliding resistance. In the present invention, the material is not limited to these. Further, the present invention is not limited to the connecting bracket extending over the circular column and the wall panel, but can be applied to the connecting bracket extending over the two equipment components arranged side by side. Furthermore, the equipment constituent members that are secured by the connecting metal fittings are not limited to metal ones, and may be, for example, wooden ones.
