Definitions

  • the invention relates to a system for conveying tennis balls with an at least approximately vertical baffle and a collecting groove arranged at the foot of the balls, to which a ramp with a rising and a falling area adjoins the playing field, the baffle or ramp with Flexible covering provided frames, consisting of telescoped pipe sections.
  • Such systems have the purpose of collecting the balls hit by a player against the vertical baffle or the ramp and feeding them to a conveyor which transports them to a container.
  • a ball throwing machine is usually connected to this container.
  • the balls can be moved in the collecting channel under the exclusive influence of gravity (cf. DE-OS 23 34 849) or using conveyor belts (cf. EU-OS 0 043 886).
  • the tennis oalls are transported from the end of the sarii channel to the collection container; Usually through a flexible hose under the influence of a suction device arranged in the ball throwing machine.
  • the balls could also be transported further via a vertical conveyor with a rotating conveyor belt, as shown in DE-OS 23 34 849.
  • DE-OS-1 428 841 shows a covering attached by means of springs to a frame, which practically always throws a tennis ball back into the area of the playground, so that it simulates a kickback of the ball by an opponent.
  • This problem is only partially solved by the loosely hanging fabric webs according to PCT-OS WO 80/01650, which is just desirable in the context described there.
  • the impacting balls are to be brought to approximately the same final speed, relatively independently of their initial speed, at which they bounce back from a rigid impact surface.
  • GB-PS 1 223 579 attempts to solve the problem on which the invention is based and to intercept an impacting tennis ball in such a way that it is not thrown back into the field.
  • a safety net is attached to side swivel arms, which allow the entire net to swing out when a ball hits it.
  • the invention achieves the same object in that the covering of the baffle and / or at least one area of the ramp is in each case only fastened to a pair of parallel edge strips of the associated frame and in that the side parts connecting the edge strips diverge under the pressure of springs arranged therein.
  • Compression springs are therefore added to the known frame constructions, the suitable strength of which can easily be determined by trial and error. If a ball now strikes the covering, in contrast to the device according to DE-OS 1 428 841, it not only has to set the covering itself, but the entire frame in motion and is thus largely independent of the type of covering intercepted.
  • the invention makes it possible to use almost any covering for the baffle wall and ramp, which, from the point of view of durability, cleanability and the like. can be selected.
  • the covering surrounds the outer edge of the edge strips, which protrude from the frame level. This prevents the tarpaulin from resting on the side parts under spring pressure and balls from these areas bouncing back into the playing field without being damped. Further details of the invention are subsequently explained with reference to the drawing.
  • FIG. 1 shows an embodiment of the invention from the side
  • FIG. 2 shows the associated top view
  • 3 and 4 represent sections of enlarged side views, partly in section.
  • the arrangement according to the invention essentially consists of an at least approximately vertical baffle wall 2, which is supported by stands 16 and, like the ramp 5 composed of an ascending area and a descending area 4, is provided with a covering 1.
  • This covering runs between edge strips 6 and 6 ', which are held at a distance by telescopically pushed side parts 8, 8 1 .
  • a joint 10 holds the ramp 5 in the position shown, so that a collecting channel 22 is formed between the ramp 5 and the baffle wall 2.
  • the tennis balls 17 in the present exemplary embodiment are conveyed by a screw conveyor 11 to an output housing 23, into which they are individually introduced by a paddle wheel 14.
  • This paddle wheel 14 is driven by means of a reduction gear 25 from the same motor 12 as the screw conveyor 11.
  • From the outlet housing 23, the tennis balls 17 are pressed into the hose 15 by a blower 13, through which they lead to the collecting container, not shown, for example a ball throwing machine.
  • the baffle 2 and ramp 5 are composed of individual parts of constant width, which makes the whole system easy to transport and can also be assembled in different widths from prepared elements
  • a single conveyor device is sufficient for tennis balls 19.
  • the screw conveyor 11 is to be provided with coupling points 31, which make it possible to piece it to any length.
  • FIGS. 3 and 4 The manner according to the invention, in which the covering 1 is fastened to the baffle wall 2 or to the partial areas 3 and 4 of the ramp 5, is shown in greater detail in FIGS. 3 and 4.
  • the edge strips 6, 6 'to form a frame connected side parts 8, 8 * springs 7, which are supported in the interior of blind holes 20 of the outer side parts 8.
  • the pressure of the springs 7 causes the covering 1 between the edge strips 6 and 6 'to be under elastic tension, which now no longer depends on the material of the covering 1, but can be determined by a suitable choice of the springs 7.
  • the edge strips 6 and 6 ' are angled twice, so that their outer edge 9 is at a distance from the side parts 8 and 8', on which they by means of screws 24 or the like. are attached.
  • the shape and arrangement of the facing edge strips 6 of the baffle 2 and ramp 5 determine the collecting channel 22, against the bottom of which the tennis balls 17 rest, while they are transported by the conveyor screw 11 consisting of an inner tube or rod 18 and a helix 19.
  • the ramp 5 Since the ramp 5 is fastened to the stand 16 by means of a joint 21 and, moreover, there is a joint 10 between the ascending region 3 and the descending region 4 of the ramp, the ramp 5 can easily be folded together in a space-saving manner if the Device is not in operation.
  • a particular advantage of the arrangement is, however, that the elasticity of the ramp caused by the springs 7 prevents damage to the ramp even when the ramp is not folded up and play increases on the covering. Sm A

Abstract

Installation de transport de balles de tennis avec au moins une paroi de rebondissement presque verticale ainsi qu'un conduit collecteur pour les balles situé au pied de celle-ci. Le recouvrement (1) de la paroi de rebondissement (2) est fixé simplement à une paire de rebords parallèles (6, 6') du cadre et les parties latérales (8, 8') reliant les rebords (6, 6') s'écartent l'une de l'autre en raison de la pression des ressorts (7) qui y sont disposés.
