Competition courts such as squash and installation method

Detailed description of the invention

[Technical Field]

The present invention provides a wall wall of a wall in a rectangular game floor (competition zone) in which front walls, back walls, and side walls are installed in front, rear, left and right. The present invention relates to a court for squash and the like, and a method of installing the ball, which is formed by hitting the ball with a racket, and more particularly, to the wall formed of a transparent synthetic resin material for convenience of field trips.

[Background]

FIG. 14 shows an example of a squash court that is currently generally used, which will be briefly described below. In the illustrated example of the squash game court 70, the floor 71 is formed of a wooden flooring material in a rectangular shape, and concrete or brick or a material of the same quality as that of the inner wall surface is finished with a flat surface without irregularities. The front wall 72, the left and right side walls 73, and the back wall 75 formed by using the transparent plate-shaped tempered glass so that the audience can observe the game from the outside.

In addition, the squash coat 70 of FIG. 14 is a regular size, and the floor 71 is 9.75 m long, 6.40 m wide, and the height of the front wall 72 is 4.75 m, and the height of the back wall 75 is 2.13 m. The upper ends of the side walls 74 and 75 are inclined by connecting the upper ends of the front wall 72 and the back wall 75, and the floor 71 and the front wall 72 are omitted in the drawings. But there is a line for the game.

In addition to the above-mentioned squash courts, there are also small ones called mini squash courts. In such a case, the floor is 5.40m long, 4.50m wide, the height of the front wall is 2.70m, and the height of the back wall is 1.80m. have.

Herein, the back wall 75 formed transparently in each of the months 72 to 75 will be described in more detail as follows. In other words, the back wall 75 is a door 80 used by players and the like to enter and exit the court, and wall surfaces 75a, 75b, 75c, and 75d made of plate glass disposed two to the left and right of the door 80. ), A door wall plate 82 disposed between the wall plates 75b and 75c, and support pillars 76 and 76 supporting the left end of the wall plate 75a and the right end of the wall plate 75d. The seam portions between 75a) and 75b and the seam portions between the wall plates 75c and 75d, and near the side ends of the door 80 of the wall plates 75b and 75c, respectively, are almost the same as the wall plates 75a to 75d. L-shaped angle members made of sheet metal or synthetic resin, respectively, with four elongated plate-like support plates 92, 92, 92, 92 of the same height having their one end surfaces abutting the wall plates 75a to 75d. 95, 95) (a pair of left and right pairs of three pairs) are fixed and supported, and all of the door 80, the wall plates 75a to 75d, the door upper wall 82, and the four support plates 92 Composed of transparent plate-like tempered glass Uh, and so it is able to see the game takes place within the court audience, including 70 from the rear side of the back March 75.

In addition, the upper and lower ends of the right end side (wall plate 75c side) of the door 80 constituting a part of the wall surface of the back wall 75 are supported by a well-known rotating support device (not shown) with an automatic return function. As shown by the dashed-dotted line in FIG. 14, the inner side of the coat 70 can be opened up to about 90 degrees, and the door 80 is automatically closed when the door 80 is released in the open state. On the outer surface (half coat 70 side) of the left end part (wall plate 75b side) of this door 80, the lock apparatus 85 for keeping this door 80 closed is arrange | positioned.

The squash court has been described above, but the racket ball court and the like are basically configured similarly to the squash court.

By the way, in the court 70 of the example shown above, only the back wall 75 is transparent, and therefore the game can only be observed from the back wall side, but for example, when a large tournament of a squash game is held, a large audience For this reason, it is strongly desired to be able to observe the game from all around the court. Therefore, the court which made all the months 72, 73, 74, and 75 transparent is already provided for practical use.

In the case of making the wall transparent as described above, it was common to use plate glass as a wall member of the wall. However, plate glass is fragile and difficult to handle. It cannot be said that there is no fear of breakage and human accidents when a strong impact is applied.

Thus, the inventors of the present application have considered using a synthetic resin material such as acrylic as a constituent member of the wall to be transparent so as to improve safety. However, it is apparent that the following problems arise when the synthetic resin material is used as the constituent member of the wall to be made transparent.

In other words, transparent materials such as acrylic have a much higher thermal expansion rate than glass, so the annual warming difference greatly expands or contracts due to changes in room temperature due to ON / OFF of cooling and heating. If the side plate is restrained by fixing the wall plate 75a to 75d constituting the wall and the support plate 90 as described above, a large gap is formed in the corner portion, or the corner portion is bent or skewed. This wall plate is bent or skewed, the wall plate and the support plate are separated, the wall plate is inclined, and the door is bent or skewed, which causes the opening and closing.

In this case, if the entire wall, wall plate, door, etc. are warped or skewed, or if there is a gap in the month, the direction of ball repulsion or the tempo of hitting the ball will be irregular and undesired, which will interfere with the game. There was a fear that the coat could not be used, in effect.

In general, a synthetic resin material such as an acrylic plate has a laminated structure in which a thin plate material such as paper is stacked in the thickness direction, so that a plate-like body having a very high height compared to the plate thickness like the wall plate or door is easily bent due to room temperature change. If the door or wall plate close to it is bent, the door may not be closed properly, and the door may not be locked, which may cause problems.

In view of such a point, the present invention can reasonably absorb thermal expansion by forming the previous month using a transparent synthetic resin material, which can prevent warpage, skewing, inclination, etc., and is comfortable. The object of the present invention is to provide a game court for squash and the like and a method of installing the same, which can safely play and reduce maintenance costs.

[Initiation of invention]

In order to achieve the above object, a competition coat such as squash according to the present invention has a front wall, a back wall, and a pair of side walls, which are installed at the front, rear, left and right sides of a rectangular game floor, each of which has a plurality of transparent resin materials. It is formed using a wall plate, and a gap is formed on at least one side of each of the walls so as to prevent the walls from being matched with thermal expansion due to room temperature change, or one end of two adjacent walls is formed. It is characterized in that both sides can extend outward so that the other end may become T-shaped.

The wall board used for the coat of this invention should just be transparent enough to be able to see the game | play made in a court from the outer periphery, and it may be a thing which colored a little and adhered the special film.

In a court for competition such as squash according to the present invention having such a configuration, a gap allowing elongation is formed on at least one side of each of the four months, or one end and the other end of two adjacent walls are formed. It is arranged to form a T-shape so that both sides can extend outward, so that each month does not hit each other in contact with each other. Therefore, even if the entire month is formed by using a transparent synthetic resin material, the thermal expansion is reasonably achieved. As a result, it is possible to prevent warping, skewing, and inclination of each wall, wall board, door, etc., as well as to play comfortably and safely, and to reduce maintenance costs.

In addition, according to the present invention, a method for installing a court for squashing or the like is used in a front wall, a back wall, and a pair of sidewalls formed by using a plurality of transparent wall plates made of a synthetic resin material. A gap is formed between each month and / or between the wall plates forming each month in anticipation of the amount of expansion in advance so as not to be hit together.

As described above, in the method of installing a court for squash, etc. according to the present invention, a gap is formed between each month and / or between the wall plates forming each month in anticipation of the amount of thermal expansion according to the change of room temperature in advance. Not only can be avoided by impact contact, but also a large gap between the walls or the wall can be avoided, and the expansion and contraction of the wall plate can cause the warp and skew. It is also possible to avoid the situation that the support plate is separated and the wall plate is inclined, and the door is warped and distorted, which causes trouble in opening and closing. As a result, the repulsive direction of the ball, the tempo of hitting the ball, and the like can be kept desired, and maintenance work and the like can be made unnecessary.

The other one of the courts for playing squash etc. according to the present invention is provided with front walls, back walls, and side walls, respectively, before and after the rectangular game floor, and at least one of the four walls is played. A transparent wall plate made of a synthetic resin material forming a dragon wall surface, a support plate made of the same synthetic resin material as the wall plate and having one end face of the wall surface perpendicular to the outer surface thereof, and a long hole having a required length in the horizontal direction An L-shaped angle member having a horizontal edge portion formed to be in contact with the outer surface of the wall plate and a vertical edge fixed to the support plate, and for connecting the wall plate and the support plate through the L-shaped angle member. It is composed of bolts inserted into a long hole formed in the horizontal edge part and screwed into the wall plate, the wall against the support plate Along the length of the long hole and is characterized in that it is elastic so as to be movable in the horizontal width direction.

This is because the wall plate and the support plate are formed of the same synthetic resin material and they are connected by bolts inserted into the long holes formed in the L-angle member through the L-angle member. The expansion and contraction in the vertical direction is absorbed by the support plate stretching and contracting at the same ratio, and the expansion and contraction in the horizontal and horizontal directions is absorbed by the bolts moving horizontally in the elongated hole as the wall plate expands and contracts.

Therefore, even when the structural member of the wall to be made of transparent material is formed of synthetic resin material, thermal expansion and contraction can be reasonably absorbed, and it is possible to prevent the occurrence of distortion and inclination on the wall plate forming the wall surface of the wall. The game can be played safely and maintenance costs are reduced.

In addition, the other one of the courts for playing squash, etc. according to the present invention is provided with a front wall, a back wall, and a side wall, respectively, before and after the rectangular game floor, and at least one of the four sides of the wall is provided. It consists of a transparent wall plate and a door made of the same synthetic resin material arranged on the same plane to each other to form a single wall surface, the door being closed so that its open end face is in contact with the end face of the wall plate. When the reinforcing ribs made of the same synthetic resin material as the wall plate are formed at the end of the one side end face on the outer surface of the wall plate, and the door is closed in the height direction of the wall plate. Integrally joined in a state partially formed laterally from one end face of the wall plate so as to receive an end of the open side; A transparent reinforcing rib made of the same synthetic resin material as that of the door is integrally joined along the height direction of the door to at least a portion near the open end of the outer surface of the door.

This is because the transparent reinforcement rib made of the same synthetic resin material as the wall plate is integrally joined to the end of one side cross-section side of the wall plate along the height direction of the wall plate so that the door side end of the wall plate is reinforced by the reinforcement rib. The warpage can be prevented.

Since the wall plate and the reinforcing rib have a laminated structure, when the cross-sections of the reinforcing ribs are bonded to the wall plate so that the laminates constituting the wall plate and the reinforcing rib are orthogonal to each other and bonded by polymer bonding or the like, their warp directions become different directions. Can be prevented from bending. Since the reinforcing ribs are integrally joined in a state partially formed laterally from one end surface of the wall plate, the reinforcing ribs serve as a stopper for stopping and catching the open end of the door.

In addition, transparent reinforcing ribs made of the same synthetic resin material are integrally joined along the height direction of the door to at least a portion near the open side of the door, so that the door is reinforced by the reinforcing ribs. The warpage can be prevented. Even in this case, since the door and the reinforcing rib have a laminated structure, when the laminates constituting the door and the reinforcing rib abut the cross sections of the reinforcing ribs with respect to the door and are joined by polymerization bonding, the direction in which they are bent is different. Therefore, it is possible to prevent the door from further bending.

Since the reinforcing ribs are made of the same synthetic resin material as the doors, even if the doors are expanded and contracted due to temperature changes, the doors are stretched at the same rate so that they are not skewed or separated, and the reinforcement ribs are transparent. Can be installed over the entire height.

(described later), and one end of the left and right sidewalls 13, 14 is the front wall as described above. Although the inner wall surface of (12) is made to contact and opposes to form a T-shape, the other end on the back wall 15 side protrudes outward than the back wall 15. As shown in FIG.

In addition, the back wall 15 is the door 20 with the lock mechanism 30 arrange | positioned at the center part, and the wall board 15a arrange | positioned at the left and right of this door 20 two each, as can be seen also referring also to FIG. 15d), four support plates 40, 40, ... arranged at right angles to the wall plates 15a-15d to support it, and the wall plates 15a-15d and the support plates 40, 40, ... It is composed of required number of L-shaped angle members 45, 45, ... (described later), and both ends of the back wall 15 impact the left and right side walls 13 and 14 due to thermal expansion caused by room temperature change. A gap S (for example, 5 to 6 mm) is formed between the both ends and the left and right sidewalls 13 and 14 in anticipation of thermal expansion in advance so as not to be in contact with each other.

As shown in FIG. 3, the lock mechanism 30 attached to the door 20 has a seesaw rocking lever 32 disposed outside the door 20, and a locking piece portion 36 for engaging the tip thereof. ), The notch insertion portion 34, and the finger insertion hole 24 for operating the lever 32 from within the court.

The wall wall 12a-12e of the front wall 12 mentioned above, the wall plate 13a-13e of the side wall 13 of the left side, and the back wall 15 of the wall plate 14a-14e of the side wall 14 of the right side. The coupling mode of the support plates 40 and 40 and the L-angle member 45 to the wall plates 15a to 15d and their structure and function will be described below with the back wall 15 as a representative.

Referring to FIGS. 2, 3, 5 and 7 (representing the joint portions of the wall plates 15a and 15b representatively), as can be seen, the wall plates 15a and 15b The joint portion and the joint portion between the wall plates 15c and 15d, and near the ends of the door 20 side of the wall plates 15b and 15c, respectively, are approximately the same height as the wall plates 15a to 15d, and made of the same synthetic resin material. Each of the elongated trapezoidal plate-like transparent support plates 40, 40, 40, 40 has a relatively large strength, such as polycarbonate, in a state in which the one end surface thereof is orthogonal to the outer surface of the wall plates 15a-15d. It is sandwiched by transparent or translucent (milky white) L-shaped angle members 45 and 45 (three pairs of left and right pairs) made of a synthetic resin material and connected to the wall plates 15a to 15d in the following manner. It is assumed here that all of the doors 20, the wall plates 15a to 15d, and the support plate 40 have the same thickness.

The lower end portions of the wall plates 15a to 15d are embedded in the grooves 36 formed in the floor 11, and can be stretched and moved in the horizontal width direction. In this case, the end face of the door 20 side of the wall boards 15b and 15c is caught by a partition wall or the like provided in the groove 36 so that it can no longer be moved to the door 20 side. When 15a-15d expands, the said wall board 15a, 15b extends toward the side wall 13 side of the left side, and 15c, 15d extends toward the side wall 14 of the right side.

In addition, the left end of the wall plate 15a and the right end of the wall plate 15d located at the left and right ends of the wall plates 15a to 15d and the L-shaped strut 35 (see FIGS. 2 and 9) and bolts described later. (51, 51) is elastically reinforced and supported.

The L-angle member 45 for connecting the wall plates 15a to 15d and the support plates 40, 40, 40, and 40 has a horizontal edge portion 45A and a vertical edge portion as shown in FIGS. 45B is formed, and the horizontal edge portion 45A is formed in the horizontal direction by a long hole 46 having a recess 46a having a required length in which the amount of expansion and contraction of the widthwise direction of the wall plates 15a to 15d is expected. It is in contact with the outer surface of the wall plate (15a ~ 15d), the vertical edge portion 45B is a bolt 42 for fixing the pair of L-shaped angle member (45, 45) by sandwiching the support plate 40 and An insertion hole 47 with a recess for inserting the nut 43 is formed.

The support plate 40 supports the vertical edge portions 45B and 45B of the pair of L-shaped angle members 45 and 45 so as to connect the wall plates 15a to 15d and the support plate 40 through the L-angle member 45. On the other side through the through-hole 48 formed in the support plate 40 from the insertion hole 47 with the concave portion formed in the longitudinal side portion 45B of one L-shaped angle member 45 in the state of being in contact with both sides of A bolt 42 having a short circumferential head is inserted into the insertion hole 47 having a concave portion formed in the vertical edge portion 45B of the L-angle member 45 so as to be different from the male screw portion of the bolt 42. The short circumferential nut 43 inserted into the insertion hole 47 with the concave portion of the L-shaped angle member 45 is screwed and tightened, and thus, the pair of L-shaped angle members 45 and 45 are supported by the support plate 40. And a bolt 41 having a short circumferential head, which is then formed in the transverse portion 45A of the L-angle member 45. 6a) is inserted into the long hole 46 and the male screw portion is screwed into the female screw portion 44 formed in the wall plate 15a to 15d so that the head of the bolt 41 is completely inserted into the recess 46a. Tighten to a degree. In the above example, two jig insertion holes 41a and 41b are formed in the heads of the bolts 41 and 42, respectively, so that the heads are inserted into the recesses of the insertion holes 46 and 47. It is for preventing the bolts 41 and 42 from being pulled out due to mischief, etc., and the bolts 41 and 42 for fixing the connection to the support plate 40 and the wall plates 15a to 15d of the L-angle member 45. This is because it is easy to remove and attach, and it is easy to attain convenience when replacing, repairing, etc. of the L-angle member 45 or the like.

Although the supporting plate 40, the L-shaped angle member 45, and the like of the back wall 15 are described above, the wall plates 12a to 12e of the front wall 12 and the wall plates 13a to 13e of the left side wall 13 are described. ), The coupling aspect of the support plate 40 with respect to the wall boards 14a-14e of the right side wall 14, and the L-angle member 45, and their structure and function are the same.

On the other hand, the L-shaped props 32 and 35 and the reinforcement column 34 provided at the four corner corners of the coat 1A are as follows. That is, the L-shaped strut 32 which reinforces and supports the wall plates 12a and 12e at both ends of the front wall 12 and the wall plates 13a and 14a at one end of the left and right side walls 13 and 14 is shown in FIG. Referring to FIG. 8 (which shows the vicinity of the left front corner of the coat 1A), as can be seen, the horizontal edge portion 55A and the vertical edge portion 55B are formed. The required number of long holes 56 with recesses 56a having the required lengths for which the amount of expansion and contraction of the front wall 12 is estimated (here, seven) is formed laterally so that the wall plate of the front wall 12 { 12d (12a)}, and the vertical edge portion 55B is a bolt 51 (side walls 13 and 14) for fixing the strut 32 to the left and right side walls 13 and 14. An insertion hole 57 having a concave portion into which the female screw portion 58 formed therein is inserted is formed, and the long hole 56 is formed in the wall plate 12d (12a) of the front wall 12. A bolt 51 screwed into the female threaded portion 54 is inserted.

In addition, the L-shaped reinforcement column 34 disposed at the corner of the four corners is disposed at the front left corner in FIG. 8, as shown by the representative of the front wall 12 and the left and right side walls 13, 14. Long holes 66 having recesses 66a having required lengths for which the amount of stretching is anticipated are formed laterally by the required number, and the long holes 66 have wall plates 12d (12a) of the front wall 12. The bolt 61 screwed into the female screw part 64 formed in (circle)} is inserted.

On the other hand, the L-shaped struts 35 disposed at the corner portions located at both ends of the back wall 15 are arranged at the right end side of the back wall 15 in FIG. 9 as a representative. And concave portions having the required lengths of the back wall 15 (the left part and the right part from the door 20 of the door 20) and the left and right side walls 13 and 14, respectively, on both sides of the vertical edge part 55D. The long holes 56 and 56 with the 56a are formed sideways by the required number (here, for example, five) in the same manner as the posts 32, and the left and right sidewalls 13 on one side of the long holes 56 and 56 are formed. Bolts 51 and 51 screwed into the female threaded portions 54 formed in the wall plates 13e and 14e of the wall plates 13e and 14e are inserted, and the wall plates of the back wall 15 (in the other side of the long holes 56 and 56). The bolts 51 and 51 screwed into the female screw part 59 formed in (15a, 15d)) are inserted.

In the above structure, the wall boards 12a to 12e of the front wall 12, the wall boards 13a to 13e of the left side wall 13, the wall boards 14a to 14e of the right side wall 14, and the bag While the wall plates 15a to 15d and the support plate 40 of the wall 15 are formed of the same synthetic resin material, they are formed by the long holes formed in the L-shaped angle members 45 by facing the L-shaped angle members 45 ( It is connected by the bolt 41 inserted in 46, and both ends of the front wall 12, end portions on the back wall 15 side of the left and right side walls 13 and 14, and both ends of the back wall 15, respectively. Is connected to the L-shaped struts 32 and 35 and the reinforcement column 34 through the bolts 51 and 61 inserted into the long holes 56 and 66, so that the wall plates 12a, 12b,. Even when stretched due to temperature change, the stretch in the vertical direction is absorbed by the support plate 40 stretching in the same ratio, and the stretch in the left and right (width) directions is applied to the bolts 41, 51, and 61. In the long holes 46, 56, 66, wall plates 12a, 12b, It is absorbed by moving to the side in accordance with the stretching movement of…).

In other words, the thermal expansion of each of the wall plates 12a, 12b falls in the left and right directions with respect to the front wall 12, as indicated by the white arrows in FIG. 1, and in the back wall 15 direction with respect to the left and right side walls 13, 14, respectively. (Back side), the left half (wall plate 15a, 15b) is absorbed by the gap S formed between the left side wall 13, and the right half (wall plate) with respect to the back wall 15. (15c, 15d)) is absorbed by the clearance gap S formed between the right side wall 14 and it.

In this example, the left half of the back wall 15 (wall plates 15a and 15b) is disposed between both ends of the back wall 15 and the left and right sidewalls 13 and 14 of the four walls 12 to 15. A gap S is formed to allow the extension of the right half (wall plates 15c and 15d), and between one end of the two adjacent walls 12 and 13, 12 and 14 and the other end. Are arranged to form a T shape so that the front walls 12 can extend outward to the left and right, and the side walls 13 and 14 can extend toward the outside (back of the back wall). Therefore, even if the previous months 12-15 were formed using a transparent synthetic resin material, the thermal expansion can be reasonably absorbed. As a result, each month 12-15, wallboard (12a, 12b, ...), the door 20, etc., can prevent the warping, skewing, inclination, etc., it is possible to play comfortably and safely as well as maintenance It is possible to reduce the ratio.

On the other hand, the door wall on the outer surface of the wall plate 15b of the same thickness and the transparent wall boards 15a-15d of the same thickness which are mutually formed on the same plane mutually forming the back wall 15 ( As shown in FIG. 3 at the end of the side 20, a transparent reinforcing rib 25 having a trapezoidal cross section made of the same synthetic resin material (acryl plate) as the wall plate 15b is located along the height direction of the wall plate 15b. In addition, when the door 20 is closed, it is integrally joined by polymerization bonding without using an adhesive in a state partially formed laterally from one end surface of the wall plate 15b so as to receive an end of the open side. It is.

In addition, transparent thin and long plate-shaped reinforcement ribs 26 and 27 made of the same synthetic resin material (acrylic plate) as the door 20 are located at both ends of the door 20 at one end thereof and the outer surface of the wall plate 15b. It is integrally joined by polymerization bonding along the height direction of the said door 20 in the state which contact | connected.

Here, the wall plate 15b, the door 20, and the reinforcing ribs 25, 26, and 27 are all made of an acrylic plate of a laminated structure, so that the reinforcing rib 25 is attached to the wall plate 15b, and the door 20 is closed. The reinforcing ribs 26 and 27 are brought into contact with each other so that the laminates constituting them are perpendicular to each other so as to be integrally joined by polymerization bonding or the like.

In this configuration, the door side end of the wall plate 15b is reinforced by the transparent reinforcing rib 25 made of the same synthetic resin material as the wall plate 15b, so that the wall plate 15b can be prevented from bending. In particular, as described above, the wall plates 15b and the reinforcing ribs 25 are integrally joined by polymerization bonding or the like by contacting end faces of the reinforcing ribs with respect to the wall plates so that the laminates constituting them are perpendicular to each other. It becomes different and can prevent the door side edge part of the wall board 15b from bending.

In addition, since the reinforcing rib 25 is integrally joined in a state formed partially in the lateral direction from one end surface of the wall plate 15b, the reinforcing rib 25 receives the open end of the door 20 and stops. It acts as a stopper to hang.

In this case, since the reinforcing rib 25 is formed of the same synthetic resin material as the wall plate 15b, even if the wall plate 15b is stretched due to temperature change, the reinforcing rib 25 is stretched at the same rate so that they are not skewed or separated. In addition, since the reinforcing rib 25 is transparent, the reinforcing rib 25 can be installed over almost the entire height of the wall plate 15b, so that the area of the part serving as the stopper receiving the open end of the door 20, In other words, since the area under pressure of the door 20 can be increased, the impact or external force is applied to the wall plate 15b and the door 20 when the door 20 is closed or when the door 20 is pushed outward. It is distributed evenly over almost all of the height of.

In addition, transparent reinforcing ribs 26 and 27 made of the same synthetic resin material as that of the door 20 are integrally joined along the height direction of the door 20 to at least a portion near the open end of the door 20. Since the door 20 is reinforced by the reinforcing ribs 26 and 27, it is possible to prevent the door 20 from bending. Also in this case, the end faces of the reinforcing ribs 26 and 27 are brought into contact with the door 20 so that the laminates constituting the door 20 and the reinforcing ribs 26 and 27 are orthogonally joined to each other by polymerization bonding or the like. As a result, their bending directions are different, and further, the door can be prevented from bending.

In addition, since the reinforcing ribs 26 and 27 are formed of the same synthetic resin material as the door 20, even if the door 20 is expanded or contracted due to temperature change, the reinforcing ribs 26 and 27 are stretched in proportion to it, thereby preventing them from being skewed or separated. Since the reinforcing ribs 26 and 27 are transparent, the reinforcing ribs 26 and 27 can be installed over almost the entire height of the door 20.

As a result, the impact and external force at the time of opening and closing the door can be uniformly distributed over almost the entire height of the wall plate and the door, and the wall plate and the door can be prevented from bending, and at the same time, Since the end portion can be prevented from being skewed or broken, it does not cause any trouble in opening / closing and releasing the door 20, so that the game can be played comfortably and safely as well as maintenance costs can be reduced.

In other words, the front wall 12 is pulled out in the right direction, the right side wall 14 is pulled out in the direction of the back wall 15 (back), and the back wall 15 is pulled out of the left side wall 13. It falls outward, and with respect to the left sidewall 13, it falls out in the front wall 12 direction (front side). Therefore, in the squash coat 1C of this example, similarly to the squash coat 1A of the first embodiment, even if the previous months 12 to 15 were formed by using a transparent synthetic resin material, the thermal expansion can be reasonably absorbed. As a result, it is possible to prevent bending, skewing, inclination, etc. in each wall 12-15, wall plates 12a, 12b, ..., door 20, etc. Etc. can be reduced.
