Wooden swing floor, preferably made of beech straps. The height of the playing field is on one of the two shorter end walls 4.57 m and on the opposite other end wall 2.13 m The boundaries of the playing field are marked by a 5 cm wide stripe, preferably a red stripe. In the case of a courtyard that can be set up in a hall, this strip is also the upper limit the side walls. Such a courtyard must be set up in a roofed room, its Height allows a free space of 6 m from floor to ceiling. Be at an outdoor farm Walls with a height of at least 6 m on all sides are required.

The squash ball game is played in pairs with a ball, which on impact or hit partially converts the impulse given to it into deformation work, which is therefore not fully elastic B'all is given alternately by both players to either of the four courtyard walls and must be struck between two successive strikes of the two Players have touched the larger end wall.

Up until now, it has largely been the practice to cast the walls of squash courts in reinforced concrete. That was also considered to be absolutely necessary, since it was previously of the opinion that essentially only concrete walls are capable of bouncing the ball in a manner suitable for the game of squash, the surface of concrete is also suitable for giving the ball the appropriate spin for the game to lend. Squash fields with concrete walls, however, have the disadvantage that they are in the production

are expensive, in particular require expensive formwork and, moreover, not without destruction to move more of the place. In addition, the walls of squash courts must be completely flat and be arranged vertically and also run parallel to one another at precise intervals. The required dimensional accuracy only allows tolerances of up to 2 mm for the dimensions given above to. Such a dimensional accuracy is very difficult with concrete walls and with a very large one Effort to achieve. After all, it is also technically difficult to produce these walls without joints, In particular, it is difficult to seal the prints of waterstops that close the formwork joints to avoid or to eliminate afterwards.

From GB-PS 14 29 635 a squash playing field / consisting of a base plate and four walls, 'which consist of plates held at a distance by struts and a filler material located in the plate gap, is known in which the walls are made by struts mutual spaced asbestos cement panels exist, in which the space between the panels is filled with concrete up to a certain level. Such squash playing fields essentially also have the disadvantages already mentioned above, which are generally associated with the use of concrete, the walls in particular also not having sufficiently good and defined rebound properties. The particular disadvantage of this squash playing field is that there the wall panels, consisting of asbestos element, are kept at a distance by a relatively massive beam construction, whereby no optimal rebound

Properties of the walls can be achieved, as the wall areas covered by the respective struts are elastically "dead" in terms of their rebound properties.

To solve the task with relatively little effort a dimensionally accurate, easy-to-build squash court with optimal rebound properties create is in DE-OS 27 31 484 a squash playing field of the generic type described in to which the I-profiles, the flange outer sides of which are firmly connected to the inner sides of the chipboard, are preferably glued, in particular made of aluminum and also the load of the roof structure be able to record.

The well-known squash playing field of the generic type has proven itself in principle, however it has been shown that with regard to the more precise 'adjustability of the rebound properties

Playing field walls as well as the exact adjustment facility as well as easy assembly of the same, overall in terms of playing characteristics, such as reliable "Disqualifying" of "out-balls" etc., still further improvements are desirable.

The invention is therefore based on the object of improving the generic squash playing field in such a way that that when optimizing the overall playing characteristics, especially the rigidity and mountability the play walls are designed more cheaply.

According to the invention, this object is achieved in a squash playing field of the generic type by the features listed in the characterizing part of claim 1

Fig. 3 shows two contiguous squash playing fields with play areas 24 or 26 on the front

ι
of the two play areas 24, 26 each has a play wall designated as a whole by 28, while a side wall 30 running perpendicular to play wall 28 is located between the two play areas 24. The playing surface 26 shown at the top in FIG. 3 is delimited on its side facing away from the playing wall 28 by an entrance wall 32, while a glass wall 34 is located at the corresponding point on the playing surface. The game walls 28, the side wall 30 and the input wall 32 are each constructed in the manner known in principle from DE-OS 27 31 484 from chipboard 20, 22, which consists of aluminum or steel by serving as vertical wall terminations U-profiles 36 Furthermore, vertical profiles, preferably I-profiles made of aluminum, are kept at a distance by not-shown, in the plate gap 38 arranged at a distance. The chipboard panels 20, 22 in the squash playing field according to the invention consist of highly compressed material with a relatively large proportion of phenolic resin, the large-area chipboard panels forming the walls of the squash playing field being made up of individual panels that are glued together seamlessly on the spot.

The coating system is a low-solvent paint system, the preferred coating being A double primer at the factory with the one available under the trade name Pefalon 115 Primer FH Material is used. When setting up the squash court Adjacent chipboard panels are then horizontally, but possibly also vertically, seamlessly glued together, with, for example, as an adhesive when assembling directly on the glued points the two-component material available under the trade name COMPAKTA PU adhesive VP 621-007 can be used. Due to the weight of the upper chipboard to be put on and inserted the adhesive is strongly compressed during horizontal gluing, with the excess material is pushed out sideways. After drying for about 1 to 2 days, the protruding Material repelled, whereupon the surface with a synthetic resin spatula, for example one under the Trade name Metall-Spachtel SCHRAMM 616/83/7500 GFS 022 available two-component spatula is used can be. This is followed by a top coat using a two-component paint system water-based with highly abrasion-resistant paint resins based on epoxy resin, also with flame-retardant additives, preferably a under the trade name Pefalon-XL top coat available material can be used. This top coat is both in its color as well

in the degree of roughness, preferably by adding sand according to the teaching of DE-OS 27 31 484, the needs of the squash game, the color is preferably a yellow-gray tinted white.

The plate gap 38 is made of annealed, so fire-dried quartz sand with a grain size of 1-3 mm filled, the momentum given by the ball after hitting one of the walls in the playing field the smaller the grain, the smaller it is. This creates a playing field set either "fast" or "slow" accordingly, depending on the climatic conditions etc. because the gas-filled squash ball is especially popular in countries with a relatively hot climate is fast, while, on the other hand, systems installed in colder climates are relatively fast must be set, because of the lower "" rebound effect there, on the gas-filled ball or its "softer" elasticity.

Fig. 3 can also be used as a vertical wall closure and for connecting abutting one another Walls, in the illustrated embodiment of the side wall 30 and the entrance wall 32 and the Glass wall 34, serving hollow support profile 40 recognize which in horizontal section essentially has a square basic cross-section.
