Definitions

  • a cover for a swimming pool with opposite side walls and opposite end walls with the cover being a sheet which in nonuse is lengthwise rolled up on a preferably springwound roll on one end wall of the pool, and in use is partly unwound from the roll and extended to the other end wall of the pool to which it is releasably anchored with its free end.
  • the cover has in opposite side margins thereof longitudinally spaced slits, and the opposite side walls of the pool are provided with claws which are manipulatable from inoperative position into operative position in which they enter the adjacent slits in the extended cover and hold the latter taut across the side walls of the pool, with the claws being releasably lockable in their operative position.
  • This invention relates to covers for swimming pools in general, and to rollable pool covers in particular.
  • the cover may first be unrolled over the pool, whereupon the same is firmly anchored to the claws on the opposite pool walls, so that covering of the pool is facile and quick, the cover is adequately tensioned and its sides are spaced so narrowly from the adjacent pool walls that children cannot fall into the pool.
  • FIG. 1 is a longitudinal section through a pool with a cover installation that embodies the invention
  • FIG. 2 is a top view of the covered pool
  • FIG. 3 is an enlarged section through one of the longitudinal pool walls.
  • brackets 5 Suitably secured to the opposite side walls 1 of a swimming pool 2 are brackets 5 which at the water level 3 rotatably and axially slidably support pipes or rods 4, preferably of aluminum. Depending on the length of the pool, one single pipe or rod 4 or several shorter lengths thereof may be provided along each side wall.
  • claws 6 Secured to the pipes 4 are claws 6 which project into slots 7 in a cover sheet 8.
  • the claws 6 are turnable with the pipes 4 and can be shifted from the full-line upper operative position into the dotted-line lower inoperative position.
  • they carry hand levers 9 which are axially slidable in holes in the pipes.
  • the hand lever 9 is slid downwardly so that the pipe 7 and claws 6 thereon are locked in operative position by this hand lever when the same rests against the side wall 1 as shown in FIG. 3. If the cover 8 is to be rolled back, the hand lever 9 is slid upwardly and pipe 4 turned clockwise (FIG. 3) to retract the claws 6 from the slits 7 in the cover 8.
  • the cover 8 is with one end suitably anchored to a shaft 10 which is rotatably supported on top of one end wall 11 of the pool, and is located in a casing 12 in which the wound-up cover is hidden and also protected.
  • the shaft 10 may, for wind-on of the cover 8 thereon, be driven in any suitable manner, such as by a crank (not shown), but is preferably spring-loaded to this end (FIG. 4).
  • a rod 13 which may releasably be interlocked with holders .14 on the other end wall 15 of the pool.
  • a line 16 Secured to the rod 13 or the cover 8 is a line 16 for handling the cover.
  • cover 8 If the cover 8 is wound-up on the spring-loaded shaft 10, and it is desired to unwind the same to cover the pool, an attendant will grasp the line 16 and proceed to the opposite end wall 15. The attendant will then unwind the cover 8 from the shaft 10 to the end wall 15 with the line 16 and anchors the same with the rod 13 behind the holders 14. The cover then sags downwardly onto the water level. One may then determine whether the claws 6 are in alignment with the slits 7, and if need be slide the pipes axially to reach such alignment.
  • the pipes 4 are at their hand levers 9 turned to project the claws *6 into the slits 7 and also tension the cover widthwise and keep it under quite substantial tension, whereupon the pipes 4 and claws 6 are locked in operative position through intermediation of the hand levers 9.
  • Both sides of the cover are then also so close to the adjacent side walls of the pool that virtually nothing may there drop into the pool.
  • the cover is also longitudinally tensioned, wherefore the cover is taut in all directions. Since such tension may be comparatively high, the cover must obviously be of a material which is highly tear-resistant and, moreover, may be wound.
  • Such a material may be suitable plastic, or even plastic reinforced by an embedded screen So (FIG. 2).
  • Such material is also heat-insulating and, hence, has the great advantage of keeing heat dissipation from the pool water at a minimum. This is of particular importance in the case of outdoor pools, because heat loss from the pool water at night or at a cloud-covered sky is negligible. This may be of equal importance in the case of indoor pools or pools with heated water.
  • the cover is preferably of transparent material to pass sun rays that heat the pool water.
  • the cover any tear-resistant and rollable material other than the one described.
  • the cover may be of canvas, or nylon or other netting, for example, as long as they are sufliciently tear-resistant and may be adequately tensioned.
  • the side pipes 4 serve also as hand rails which are highly desirable in pools.
  • the cover is adaptable to all kinds of pools, such as concrete, steel, aluminum and other pools. Furthermore, the cover may readily be installed in existing pools.
  • cover casing 12 may be of neat appearance so that the pleasing appearance of the pool is in no wise adversely alfected.
  • a cover installation as in claim :1 in which the pool has a given water level, and said rails are substantially at said water level.
