DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a playground equipment mainly intended for use by infants and children (hereinafter collectively referred to as "children"), and more particularly, to a playground equipment for hanging or riding these persons. The present invention relates to a net-shaped play equipment that can be used.

[0002]

2. Description of the Related Art Hitherto, many playground equipments installed in parks and the like have a fixed form such as a slide, an iron bar, and a jingle gym. On the other hand, rocking playground equipment represented by seesaws and swings also depend on fixed mechanical and mechanical structures, and their movements are standard. Therefore, when using these playground equipment, there is no way to play other than performing a prescribed exercise defined by the structure of the playground equipment. The children who were looking for a good play were immediately reluctant to use it, and were not actively used except for those who were in the early stages of play, such as infants. Also, these conventional play equipment, for example,
It was made of a hard material such as stone, concrete, iron, etc., and there was a danger of a hit accident and the like.

In view of the above-mentioned problems of the prior art, the inventor of the present application has disclosed Japanese Utility Model Laid-Open No. 55-131267 and Japanese Utility Model Laid-Open No. 55
No. 26859 proposes a net-shaped playground equipment, and this playground equipment is now widely used in various places. The former play equipment is characterized in that it has a swing hole made of a net-like bag unit containing a sphere inside the lower end of an inverted conical net-like bag that is extendable and contractable and has a closed end. This is a net-shaped playground equipment provided with a bag unit in which a sphere is stored in the lower end of the bag to be hung from the net body of the playground equipment. Further, the latter play equipment has a circular or elliptical outer shell, and is provided with a net unit having a hole at a position deviated from the center thereof. It is a net-shaped playground equipment provided with a bag unit provided with a hole through which a user can enter on the side of the bag body to be hung down.

Each of the bag units disclosed in Japanese Utility Model Laid-Open No. 55-131267 and Japanese Utility Model Laid-Open No. 55-126859 is used in such a manner that a plurality of the bag units are provided together with one net-shaped playground equipment. There are various ways to play with this playground equipment, and they are not described uniformly.However, in the case of the former bag unit, for example, the user puts his feet on the sphere of the bag unit, You can rock and swing, roll up and enjoy the reverse, or climb up and play with several people. In addition, with regard to the latter bag unit, a user enters the bag body through the hole on the side surface and swings freely, moves freely, or can travel along the inside of the bag body to the net body of the playground equipment. .

[0005]

However, in the above-mentioned net-shaped play equipment, since the user hangs or rides on the net and each unit hanging therefrom, the play equipment must be suspended from the structure. I had to. Specifically, by adding a starfish-shaped or star-shaped extension to the outer peripheral edge of the net body of the playground equipment, by suspending each extension from a plurality of vertical pillars arranged at equal intervals on the circumference. , And supported between a plurality of vertical columns in a stretched state.

In this case, since the supported play equipment is premised on that a plurality of users hang or ride at one time, a large hanging load is applied to each of the vertical pillars suspending it. First, the vertical pillar itself must be made of a material and thickness having a strength enough to withstand this load. Second, the vertical pillar must not be buried and fixed in the installation place with a strong foundation. I didn't have to.

[0007] For this reason, the above-mentioned play equipment requires a large amount of civil engineering work for its installation, and may not be installed on a place other than the ground, for example, on an upper floor of a building having insufficient strength. Naturally, the installation is permanent, and it is unsuitable for the purpose of temporary installation at an arbitrary place, and the portability is poor due to the heavy weight of the vertical column itself.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems specific to the net-shaped play equipment, and makes the structure for hanging the play equipment more rational. It is another object of the present invention to provide a net-shaped playground equipment having a suspending means which can be installed in a short time and with a simple method.

That is, the net-shaped play equipment provided with the suspending means of the present invention comprises a plurality of vertical pillars arranged at equal intervals on the circumference and an X-shaped arrangement between adjacent vertical pillars. At the top of a planar polygonal frame composed of brace columns that are joined and joined at the intersection of the X-shape and arch columns that are arranged and joined in an arch shape between the upper ends of adjacent vertical columns,
A self-standing structure is constructed by arranging a lattice-shaped ceiling member with each arch column as a connection point, and a net-shaped playground equipment made of a non-rigid material that allows users to hang or ride And is suspended inside the self-supporting structure so that a pulling load is applied above the self-standing structure.

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view showing the entire net-shaped play equipment provided with the suspending means of the present invention. The present invention is composed of a net-shaped play equipment 20 and a structure 1 for suspending and supporting the play equipment. First, the play equipment 20 as a premise of the present invention will be described.

FIG. 6 is a diagram showing the playground equipment 20 in an exploded state. The net-shaped play equipment 20 itself is the same as that of the above-described actual open flat 5.
No. 5,131,267 and Japanese Utility Model Laid-Open No. 55-126859. Here, a bag unit 26 (disclosed in the former) in which a sphere 27 is stored in the lower end of the bag and a bag unit 2 in which a hole 25 through which a user can enter is provided on the side surface of the bag.
4 (disclosed in the latter) is suspended from the net body 21 to be hung on the structure 1. Since these details are disclosed in the above-mentioned publications, only a minimum description of the embodiments will be given here.

The net main body 21 constituting the above-mentioned play equipment 20
The bag units 26 and 24 are all constituted by nets. This net is obtained, for example, by knitting a braid made of a braid of a non-rigid material such as nylon, vinylon, or polyester fiber.The knitting method is stretchable and the stitch does not pass through the foot of the child, However, it is desirable that the fingertip or toe can be hooked (usually a pitch of about 5 cm).

The net main body 21 is formed in a shape (here, circular) which can be supported in a stretched state within the structure 1 described later, and is suspended from the outer peripheral edge to each vertical column 2 of the structure 1. Ropes 23 are extended at required intervals.

A bag unit 2 containing a sphere 27 in the lower end
6 are suspended from the net main body 21 by a required number. In this embodiment, the bag of the bag unit 26 has an inverted conical shape having a closed end at the lower end, and has a bottom portion extending to a cylindrical bag portion, in which a sphere 27 is accommodated. The sphere 27 may be accommodated from the open conical portion above the bag unit 26, or the sphere 27 may be initially placed at the tip of the mesh bag 1 to knit the bag unit. The sphere 27 can be swung wobbled by the user hanging or riding on it, which is housed in the hanging bag body as a clue or a foothold (FIG. 7).
(See diameter of about 30 cm), but those having different sizes so that children of various ages can use them may be provided in one playground equipment. In this embodiment, the sphere 27 is assumed to be, for example, a float-like one used in fisheries or a hollow and lightweight one such as a rubber ball, and the surface is colored. The upper edge of the bag unit 26 is fixed to the back side of the net body 21 with the upper conical opening part opened.
Here, for the purpose of putting the spherical body 27 in and out, a hole 22 through which the spherical body can be put in and out is provided at the location of the net main body 21 where the cone opening is located.

On the other hand, a required number of bag units 24 having holes 25 through which a user can enter are provided on the side surface of the bag body. In this embodiment, the cross-sectional shape of the bag is circular or elliptical, and a hole 25 is provided in the lower side surface. The diameter of the hole 25 is small enough to allow one child to pass through and enter the bag (see FIG. 7).
It is preferable that the stitches are arranged slightly densely around the periphery, and the innermost peripheral edge is tightly knitted so that the periphery of the hole does not stretch.
Although not shown in this embodiment, a plurality of bag units 24 may be stacked, and the bags may be joined to the bags of the upper (or lower) bag units. In this case, when the user falls down (falls) from one hole of the upper-layer bag unit 24, there is always the lower-layer bag unit 24 thereunder, so that it is possible to prevent the user from directly falling to the ground. Safety effect is obtained. The upper edge of the bag unit 24 is fixed to the back side of the net body 21 with the upper conical opening part opened. Here, a hole 22 through which the user can enter is provided at the position of the net main body 21 where the conical opening is located so that the user can move between the inside of the bag unit 24 and the main body 21.

Next, the structure 1 which is a feature of the present invention will be described. The structure 1 is formed of a plane polygonal frame that supports the net-shaped play equipment 20 in a suspended state therein. In this embodiment, a plane octagonal frame having eight vertical pillars 2 is taken as an example, but the number and the plane shape of the vertical pillars 2 are of course not limited thereto. The vertical pillars 2 are arranged at equal intervals on the circumference in a standing state, so that they are located at respective vertices of a polygon (here, an octagon), and these become vertical pillars of the frame.
These vertical columns 2 are arranged and connected in an X-shape between adjacent ones, and are connected by brace columns 3A and 3B connected at intersections of the X-shape. Further, the adjacent vertical columns 2 are connected by an arch column 7 arranged and connected between the upper ends thereof in an arch shape.

The vertical column 2 is subjected to the tensile load of the net-shaped play equipment 20 suspended at the upper end in the same manner as the above-described vertical column. However, as described later, in the present invention, the load is not distributed by the vertical column 2 alone, but is distributed to the entire frame constituting the structure 1 by being combined with the other columns and the ceiling member. As a result, the vertical column 2 itself does not need to have the strength required for the prior art vertical column. The vertical column 2 is of course rigid, but may have a slight degree of bending due to external force. Specifically, in addition to metal, it may be made of plastic, glass fiber, wood, or the like, or may be a hollow pipe. In this embodiment, as the vertical pillars 2, wood processed into a cylindrical shape is adopted, but this is an example. In addition, other brace pillar 3
The situation is exactly the same for A and 3B and the arch column 7, and in this embodiment, the brace columns 3A and 3B are also made of cylindrically processed wood, and the arch column 7 is also made of metal pipe. However, this is also an example.

The brace columns 3A and 3B are concretely the vertical columns 2
Is bridged from the upper end to the lower end of the adjacent vertical column 2 in an X-shape. In this embodiment, the strut column connecting the adjacent vertical columns is not formed as two crossing struts, and the lower strut column is not formed. 4 for 3A, 3A and upper brace post 3B, 3B
Divided. These strut columns are connected by a four-way joint sphere 4 having connectors on all sides of the sphere, so that four are connected at the intersection of the X-shape.
The lower brace pillars 3A, 3A are connected to the lower ends of the adjacent vertical pillars 2, 2 via plate-like joint plates 5, 5, and the upper brace pillars 3B, 3B connect the connectors to the five sides of the sphere. It is connected to the upper ends of the adjacent vertical columns 2, 2 via a five-way joint sphere 6. In this embodiment, the upper brace columns 3B, 3B are curved upward for the reason described later.

The upper ends of the adjacent vertical columns 2 are connected by arch columns 7. The arch pillar 7 has an upwardly curved shape, and is connected to the upper ends of the adjacent vertical pillars 2 and 2 via the five-way joint spheres 6 so that both ends are connected in an arch shape between the vertical pillars. It is.

A ceiling member 10 is connected to the upper part of the above-mentioned plane polygonal frame by using each arch column 7 as a connection point, whereby a self-standing structure is completed. The ceiling member 10 has a structure in which vertical and horizontal wires 11 and 12 are connected in a lattice shape. The ceiling member 10 may have a certain degree of bending due to an external force, as a matter of course, having rigidity. Specifically, in addition to metal, it may be made of plastic, glass fiber, wood, or the like. In this embodiment, wood processed into a plate shape is used, but this is an example.

When the structure 1 is installed, the structure 1 is placed as it is on an artificial ground such as the ground or concrete, and is fixed thereto by driving an anchor. In the drawing, reference numeral 9 denotes an installation plate provided at the lower end of each vertical column 2 for driving and fixing an anchor. still,
In this embodiment, the adjacent vertical columns are connected to each other at the lower end of each vertical column 2 by the horizontal columns 8.
Is not a requirement of the present invention, and its addition is optional.

The net-shaped play equipment 20 is supported in a suspended state inside the structure 1 described above. It is desirable that the play equipment 20 be suspended so that a pulling load is applied above each vertical pillar 2 of the structure 1. In order to realize this, in this embodiment, the net main body 21 of the playground equipment 20 is used.
After hanging each rope 23 extending from the outer peripheral edge of the vertical column 2 on the pulley 30 attached to the upper end of each vertical column 2 and the five-way joint ball 6 connecting the brace column 3B and the arch column 7, the ends are each vertical column. 2 is fixed to a joint plate 5 connecting the lower end of the strut 3A and the brace post 3A. Under the structure 1 on which the play equipment 20 is supported in a suspended state, sand covering the installation surface is scattered (not shown) to reduce the impact when the user falls.

[0023]

According to the present invention, it is possible for a user to freely, freely, creatively and systemically exercise with a net-shaped play equipment.
Japanese Utility Model Laid-Open No. 55-131267 and Japanese Utility Model Laid-Open No. 555-1
As is known in Japanese Patent No. 26859, according to the present invention, the following unique effects are exhibited with respect to the suspending means, and the use of the playground equipment is widened. When a downward load is applied by the suspended net-shaped play equipment, the vertical column 2 tries to bend inward, but the force is applied to the strut columns 3A, 3B bridged between the vertical columns 2.
In addition, the arch column 7 is dispersed in the direction in which the arch column 7 is to be bent and received by the entire frame body, and this force acts to narrow the frame body. In this case, since the lattice-shaped ceiling member 10 is connected to the arch pillar 7 that constitutes the upper edge of the frame, the force for narrowing the frame increases the ceiling member 10 this time. It is distributed and received in the direction in which it is bent and pushed up. In this case, the upper brace pillars 3B, 3B may be bent upward as in the embodiment, or the play equipment 20
Is not provided directly on the vertical column 2 but on the five-way joint sphere 6 connecting each vertical column with the brace column 3B and the arch column 7, instead of directly providing the pulley 30 on which the hanging rope 23 is hung. It is effective in promoting. As described above, the downward load due to the playground equipment is received not only by the vertical pillars but also by the entire structure as in the prior art, so that not only the vertical pillars but also the members constituting the structure are made as thin as possible. It is possible to configure, and the restrictions on the materials are relaxed. Due to the above effects, each member constituting the structure is lightened so that only one member can hold it. As a result, the structure can be easily assembled and disassembled, and the structure can be installed and removed with a small number of hands (two people). Since the structure constituted by the frame has autonomy, and also distributes the load uniformly throughout the structure as described above,
The means of fixing to the installation surface is minimal, and no special civil works as in the prior art are required. As a result of the above, as a result, a net-shaped playground equipment that is highly portable and has hanging means that can be easily installed and removed can be realized. Becomes As described above, the material of each member constituting the structure is also loosened, and as a result, it becomes possible to use wood as in the example, and the metal of the prior art has been forced to use metal due to the problem of strength. As compared with the suspending means, the portion touched by the user is softened and the safety is improved.
