Device for rolling up and unrolling swimming pool covers and freeing the beach. The invention relates to a device which makes it possible to roll up, unroll the cover of the swimming pool and very easily release the beach on which the device is fixed. It consists of two supports (1) fixed to the ground, which each receive an axis (2) on which the arms (3) pivot. The arms (3) support the tube (5), axle (6), tarpaulin (7), crank (9) assembly, and the vee-shaped rollers (8) which move and are guided on the arms (3) thanks to the vee-shaped rollers (8). The arms (3) are kept horizontal thanks to the crutches (11). The operator, to release the range, unlocks the hooks (10), pushes the tube (5), axle (6), tarpaulin (7) crank (9), and vee-shaped rollers (8) assembly against the hooks (4). It can then very easily rotate the arms (3) one after the other, the crutch (11) pivots with its own weight at 180 degrees around the axis (12) and is found in contact with the ground on the side. opposite the basin then supporting the arms (3) horizontally. The reverse operation allows the tube, axle, cover, crank and rollers assembly to be brought back into position, in order to unroll the cover over the basin.

Description

The present invention relates to a tarpaulin reel / unwinder of

cover of

  swimming pool which frees up the beach.

  The cover of swimming pools is traditionally carried out using a mobile reel / unwinder on wheel without fixed points, which does not facilitate the alignment of the tarpaulin s on the water, because it is necessary to move this reel / unwinder to free the pool deck during the bath, which means realigning it each time the tarpaulin is replaced

on the water.

  Despite its mounting on a wheel, the movement requires a significant force

  can only be performed by an adult.

  0 This winder / unwinder is sensitive to wind and it is not uncommon for it to be knocked over

during gusts of wind.

  Given the drawbacks described above, it is common for users to avoid moving it, which has the effect of leaving the beach congested

by this winder / unwinder.

  The reel / unwinder according to the invention overcomes these drawbacks.

  Indeed, the invention comprises two points of attachment to the ground, which forces the sheet to unfold properly on the water and prevents the reel / unwinder from overturning

under the action of the wind.

  This reel / unwinder by its design allows a young child to handle it effortlessly and without precision, to roll up or unroll the tarpaulin and especially to be able to very easily release the beach. In fact, the weight of the assembly is never supported by the person handling it, the reel / unwinder consisting of two arms articulated on two supports fixed to the ground. The user moves by pushing the whole of the wrapped tarpaulin on an axis in the direction of the articulation points, which has the effect of increasing the lever arms constituted by the articulated arms and therefore transferring the weight of the assembly near the axis of rotation. It remains for the user to tilt the arms one after the other, while they are practically relieved of their weight. The beach is freed. The reverse maneuver will be practiced to bring the tarpaulin back into position

pool cover.

  The invention relates to a device for winding and unwinding at least one swimming pool cover covering comprising a cover winding shaft, the maneuvering means for rotating the winding shaft and two support assemblies which support the ends of the shaft, characterized in that the two assemblies are arranged substantially parallel to one another, and in that each support assembly comprises: A support (1) for anchoring to the ground. An arm (3) articulated on the axis (2) of the support (1) and movable between a position remote from the pool and a position -2- close to the pool. Fastening means (4) and (10) of the winding arUre on the arm (3), on the one hand near the support (1), and on the other hand at the end of the

  arm (3) located opposite the support (1).

  According to a characteristic of the invention, each arm (3) defines a rolling track for the winding arUre during its passage from the fixing means (4) located

  near the support (1) by means of flxation (l O) located opposite, and vice versa.

  The accompanying drawings illustrate the invention:

  Figure n 1 represents the b3che in position to be unrolled on the basin.

  Figure 2 shows the cover in the position to be tilted to release the

lo beach.

  Figure 3 shows the tilting of a first arm.

  Figure 4 shows the tilting of the second arm and therefore the

liberation from the beach.

  Figures 5a, 5b, 6a, 6b and 7a, 7b show the movement of the hooks

  arranged opposite the point of rotation of the arms.

  With reference to these drawings, the apparatus consists of two independent support assemblies, not connected one to the other, each being fixed to the ground and spaced one from the other by an equal interval. approximately at the side of the basin on which the reel / unwinder is placed. These two sets are identical, each of the parts the

constituent can be interchanged.

  Each set consists of a support (1) used for anchoring to the ground and for

  fixing an axis (2) supporting and allowing the rotation of an arm (3).

  The arm (3) consisting of a rectilinear piece of rectangular, square or other section, without excluding other profll, is pierced at one of its ends to

  receive the axis (2) connecting it to the support (1) thus forming a joint.

  The arm (3) is provided on the support side (1) and a few centimeters from the axis (2) of a fixing means (4) represented by a hook in cane beak welded or mechanically fixed, which serves to retain the '' winding shaft of the tarpaulin comprising the tube (5), the axis (6), the tarpaulin (7) the rollers with V-shaped shoulders (8) and the crank (9) in the rolled up position and released from the range, this hook (4) can be replaced by any other locking means for example (magnet, spring, ramp). This same arm (3) is provided at its other end with a fixing means (10) represented by a hook of the same shape (cane beak), but axially movable (according to the arrows indicated on the

  sketch fig. 1 and fig. 2) allowing the hook (10) to go up and down in the arm (3).

  This hook (10) can also be replaced by any other locking means in the same way as the hook (4). This hook (10) serves to immobilize the tube (5), the axis (6), the tarpaulin - - 3 (7) the rollers with V-shaped shoulders (8) and the crank (9) during the winding maneuver and unwinding. This hook (10) is fitted onto a v-shaped roller (8) which guides and

  supports the tube (5), the shaft (6), the cover (7) and the crank (9).

  This explains why: s When the hook (10) is lowered in the central part of the v-shaped shouldered roller (8) (fig.5), the shouldered v-shaped roller (8) is blocked, but the axle (6) of the tube (5) man_uvré by the crank (9) or possibly by a handwheel, can freely rotate in the roller supported in vee (8) and ententner the tube (5) which allows the winding or the unwinding of the tarpaulin ( 7) (fig. 1). When this cover (7) is too heavy the effort on the crank (9)

  0 can be multiplied by a gear play or by any other means of reduction.

  For example, it suffices to fix the crank (9) on the arm (3) on the side of the hook (1 û). We will fix on the axis of the crank (9) a pinion with fewer teeth than that which will be fixed on the axis (6). When the user takes the tube assembly (5) axis (6) tarpaulin (7) rolled shouldered roller (8) against the hooks (10) the two pinions will drive. The effort to be made to roll up or unroll the sheet will depend on the reduction ratio of these

two gables.

  When the hook (10) is lifted, the v-shaped roller (8) ffig.6) is released. It suffices to push the tube (5), axle (6), tarpaulin (7), crank (9) assembly so that the shouldered roller in vee (8) moves by turning on the arm (3) ffig. 7) and go to lodge against the fixed hook (4) ffig. 2). It will suffice to tilt the arm (3) ffig. 3) to about 180, depending on the condition of the ground, so that the shouldered roller in vee (8), therefore the assembly (5,6,7 and 9) rolls to the inside the hook (4), get trapped at the bottom of the hook (4) and stops near the axis (2) of the support (1). The range will thus be free, when the two arms (3) have been tilted

  one after the other, by one person (fig. 4).

  The reverse operation will allow the tube (5), axle (6), tarpaulin (7), crank (9), v-shaped rollers (8) rollers to be brought back into position to unroll the tarpaulin (7) on the basin. The arm (3) will also receive a crutch (11) centered on a side (right or left depending on whether it is the right arm or the left arm) which will pivot around the axis (12) under the action of its own weight, at the same time as the arm (3) pivots on its axis (2). Ceffe crutch (11) will support the arm (3) in the two horizontal working positions of the arm. The attached sketches explain the method of manufacture and handling of the device.
