Definitions

  • ABSTRACT This invention describes a device for protecting coverings of inflatable halls, particularly inflatable tennis halls (covered tennis courts) from mechanical damages, which coverings are provided on the inner hall side in the range in which hit tennis balls might possibly strike on the covering wall.
  • the protective device is a resilient skirt mounted on stands, which extends at [56] References Cited a spacing parallel to the inner hall wall and is of 21 UNITED STATES PATENTS height up to which tennis balls can be expected to im- 843.326 2/1907 Chapin 273/29 B p c in p ay an np o ec ed covering.
  • a protective device which is a resilient skirt mounted on stands and extended at a spacing parallel to the inner hall wall and up to a height to which tennis balls can be expected to impact in play an unprotected covering.
  • the attachment of the impact skirt which may also be a net which, according to one embodiment of the invention, consists of meshed wire, on individual stands provides the advantage that the protective device can be mounted ata desired location on the hall base independently of the construction of the hall.
  • a continuous material web is also suited, such as a cloth.
  • the impact skirt prevents the hit tennis balls which usually have relatively high kinethic energy from contacting the relatively sensitive covering foil, and it simultaneously prevents tennis balls contacting it from rebounding into the court.
  • the protective device can be arranged in front of each of the hall walls, but the compared to the use of meshed foils and by which a better protection from damages by hit tennis balls can be attained than is possible with the aid of welded-on meshed foil, but which can be mounted also independently of the covering wall.
  • a further object is to provide a protective device the height of which can be adjustable, in order to thus provide a possibility to arrange the skirt at various levels as required.
  • An additional object is to provide the stands on which the skirt is mounted with means to mutually support the stands so that they are also supported against the hall base by lateral or rear supports which prevent them from tipping over.
  • FIG. 1 a cross-sectional view of an inflatable hall with a protective-device according to the invention arranged It is known in connection with inflatable halls'used as 5 at the front face, and
  • FIG. 2 a partial longitudinal section of the hall as shown in FIG. 1, from which the arrangement of the protective device at the hall end can be seen.
  • the inflatable hall I that is under inside positive pressure comprises covering 2, which is anchored in per se known manner laterally in the base 3.
  • a protectivedevice 4 is installed transversely to the longitudinal hall direction behind each court end, said device consisting of stands 6 arranged at a spacingadjacent one another and of a skirt-like materialweb 5 se- Cured to the stands, the other rim of which extends approximately to the height, which it is expected that tennis balls hit beyond the court end will reach.
  • the stands 6 are mounted on the hall base 3 and can be anchored in the base by suitable means or can be supported against the hall base with the aid of supports mounted laterally and at the rear, so that they will not tip over when balls strike the skirt 5.
  • the skirt 5 can be mounted on the stands in such a manner that it depends down to the hall base 3, so that balls rolling beyond the court edge cannot roll behind the skirts.
  • the halls striking the skirt pass their energy of motion entirely onto the skirt without any forces whatever being transmitted in that regard to the covering 2 of the hall, because neither the stands nor the skirt are in communication with the covering. After striking the skirt, the balls drop down on the skirt without rebounding into the court, because the limp skirt is not capable of transmitting impact forces to the balls striking it.
  • the spacing of the stands 6 from the net 7 is selected such that a distance in accordance with regulations is maintained between the stands and the inner side of the covering.
  • the height of the stands can be adjustable by conventional adjustable means in order to thereby be ableto adapt the skirt height to the maximum height at which balls are expected to strike.
  • the skirt itself can either be a continuous material web, i.e., a clothreinforced foil, or it can also be a net consisting e.g., of meshed wire.
  • a protection device of this kind cannot only be arranged at the front ends of the court, but also longitudinally of the court edges, so that then the hall covering surrounding the court is'entirely covered byprotection devicesof this type.
