Description

  The present invention relates to a wall surface structure that forms a wall surface of a competition court such as a padel or a squash in which a ball is hit against a wall surface with a racket.

In recent years, squash, padel, etc. (hereinafter also referred to as racquetball) are becoming popular in Japan. Both squash and padel are similar to tennis, but at least on the court surrounded by walls.
Squash hits the ball alternately using rackets in singles, and all the hits need to hit the front wall, but other walls may be used.
Padel is a rule similar to tennis, but it is a competition that is played on a court surrounded by walls and can be played back using the walls.

Examples of the invention relating to the racket ball competition court include the following.
In Patent Document 1 below, a front wall, a back wall, and a pair of side walls that are erected on the front and rear and right and left of a rectangular game floor are formed by using a plurality of transparent wall plates each made of a synthetic resin material. In order to prevent the walls from being pressed against each other by thermal expansion due to a change in room temperature, a gap that allows the walls to extend is formed on at least one end of each wall, or one of the two adjacent walls A squash or other competitive court is shown, characterized in that one end and the other end are arranged so as to exhibit a T-shape, and both can be extended outward. It is designed to absorb the expansion of various synthetic resin materials.

  In Patent Document 2 below, a front wall, a back wall, and a side wall are erected on the front, back, left and right of a rectangular game floor, respectively, and at least one of the four walls forms a wall for competition. A transparent plate-like wall made of a synthetic resin material, and a plate made of the same synthetic resin material as the plate-like wall and having one end face abutted so as to be orthogonal to the outer surface of the plate-like wall -Shaped reinforcing support, a lateral side portion in which a long hole having a required length is formed in a lateral direction and is brought into contact with the outer surface of the plate-like wall body, and a vertical side portion fixed to the reinforcing support body In order to connect the L-shaped angle member, the plate-shaped wall body, and the reinforcing support through the L-shaped angle member, the L-shaped angle member is inserted into an elongated hole formed in a lateral side portion of the L-shaped angle member. The male threaded portion of the lever is the plate wall The plate-like wall body can be expanded and contracted in the lateral direction in accordance with the length of the long hole with respect to the reinforcing support body. A squash and racquetball competition court is shown, which is adapted to absorb the expansion of a transparent synthetic resin material.

  In Patent Document 3 below, a plurality of divided bases are connected using bolts or the like so that they can be separated as needed to assemble a rectangular frame base, and a plurality of divided wall bodies are bolted to the frame base. It is attached so that it can be removed if necessary using a kind etc., and the adjacent ones of the divided wall bodies are connected so that they can be separated if necessary using bolts etc. A competition court such as a squash is shown which forms a wall, a back wall, and left and right sidewalls, and a competition court such as a squash or padel can be easily installed and removed.

The competition courts described in Patent Documents 1 to 3 use a transparent wall plate on the wall surface, so that the competition can be observed from the outside of the court and can be enjoyed by the spectators.
However, in the vicinity of the boundary between the wall plates, a columnar support plate or the like is provided to support the wall plates, and such a support plate may block the sight of the spectator and make it difficult to see the competition. Further, there has been a problem that the wall surface is distorted by the thermal expansion of the member.

  Accordingly, an object of the present invention is to provide a wall surface structure of a racket ball competition court that improves the sight of the spectator and makes it easier to watch the competition, and further, due to the difference in thermal expansion between the frame and the transparent plate material. To provide a wall structure in which wall distortion is less likely to occur.

  The wall surface structure of the racquetball court according to an embodiment of the present invention is formed by connecting at least two vertical frame members rising at an appropriate interval and at least two horizontal frame members with a gap therebetween. There is an upper frame member that spans the upper end side of the vertical frame member, a bracket that has a laterally long hole, and is fixed to the upper frame member, and a hole that is provided in a plurality of transparent plates arranged in parallel with each other. And a fastening member that is inserted and fixed into the laterally long hole while being inserted through the horizontal hole.

  By adopting such a configuration, the wall surface of the racket ball competition court can be formed without providing a pillar or the like between the plurality of transparent plate members, the sight of the spectator can be improved, and the competition can be easily observed. The upper frame member is formed by connecting a horizontal frame member with a gap, and the transparent plate member and the upper frame member supporting the transparent plate member are fixed by inserting a fastening member into the horizontal elongated hole. Therefore, even if the upper frame member or the transparent plate member expands or contracts due to thermal expansion, it is possible to prevent the wall surface from being distorted due to the difference in thermal expansion coefficient.

  The wall surface structure of the racket ball competition court of the above aspect is provided with a gap in the vertical frame member, and provided in the lower frame member arranged on the lower end side of the vertical frame member and the lower frame member A hole and a fastening member that is inserted into and fixed to the hole of the lower frame member while being inserted into the hole provided in the transparent plate member.

  By adopting such a configuration, the lower frame member for fixing the transparent plate material is arranged with a gap in the vertical frame member, so even if the lower frame member expands due to heat or the like, it interferes with the vertical frame member. The vertical frame member is not easily distorted without doing so.

  The wall surface structure of the racquetball court in the above-described form includes a connector for connecting two horizontal frame members, and the connector can be formed integrally with the bracket.

  By setting it as such a structure, it can have the function of a coupling tool and a bracket, and construction of a wall surface can be performed easily.

  In the wall structure of the racquetball court in the above form, the vertical frame member, the upper frame member, and the lower frame member can be formed of an aluminum material.

  With such a configuration, the weight of the frame can be reduced, and the construction work can be facilitated. Moreover, even if the wall surface of the racket ball competition court is formed of an aluminum material having a high coefficient of thermal expansion, it is possible to prevent distortion due to heat.

  It is possible to create a racket ball competition court having the above-described wall structure. Since this competition court has no pillars or the like between the transparent plates, the field of view of the spectator is good and the competition can be easily observed. In addition, there is a merit that maintenance is easy because the wall surface is not easily distorted by heat.

It is the perspective view which showed an example of the court for padel competitions using the wall surface structure of one Embodiment of this invention. It is the front view which showed the wall surface structure of the court for padel competition of one Embodiment of this invention, and visually recognized the front wall from the court side. It is the disassembled perspective view which showed the connection part vicinity of the upper side frame member used for the wall surface structure of FIG.
