A shiftable wall for swimming pools

Abstract

 This shiftable wall is made up by a transversal bridge (2) resting on the lateral edges (6 and 7) of the swimming pool (3) by means of wheels (8 and 9) running on rails (10) being provided at said edges (6 and 7) of the swimming pool (3). This shiftable wall is characterised in that the rolling ends of the bridge are each linked to a respective rope (16 and 17) forming a respective guided loop and being driven by a motor (19). The ropes (16 and 17) run along a path being guided by pulleys (18) and have their ends linked to a drum (20) having a helical periphery and being driven by the motor (19), and the wall is made up by a framework (14) at its front and back faces comprising grid panels (15).

Description

OBJECT OF THE INVENTION

[0001] A shiftable wall for swimming pools.

BACKGROUND OF THE INVENTION

[0002] As is known, a swimming pool will have to be of some given dimensions according to the use for which it is intended. For example the swimming pools for children are of more reduced dimensions as compared with those being intended for adults, said dimensions being bigger in the case of the competition swimming pools.

[0003] Having several swimming pools with different dimensions represents a big space requirement and a high cost for building them.

[0004] In order to solve this problem some swimming pools have been provided with a shiftable wall allowing to have them divided into two spaces of different dimensions. Said wall is shiftable along the length of the swimming pool and is made up by a bridge being arranged in a transversal arrangement and resting at its ends and by means of wheels on the lateral edges of the swimming pool, said lateral edges being provided with the corresponding rails.

SUMMARY OF THE INVENTION

[0005] It is the object of this invention to improve this type of shiftable walls as regards both their make-up and their operation.

[0006] For such a purpose the shifting of the wall is obtained by linking each of its rolling ends to a respective hauling rope forming a guided loop and being driven by a motor.

[0007] The ropes run along a pulley-guided path and have their ends linked to a drum having a helical periphery and being driven by the motor.

[0008] The shiftable wall structure is made up by a framework comprising several lengths being joined together, the front and back faces of said framework being formed by grid panels.

[0009] The wheels are of the double-wheel type and are divergently tapered at their periphery in correspondence with the tapers of the rail.

[0010] The shiftable wall ends have been each provided with a respective resilient edge in order to thus have them properly adapted to the swimming pool vessel.

[0011] These and other characterising features will be best made apparent by the following detailed description whose understanding will be made easier by the accompanying two sheets of drawings showing a practical embodiment being cited only by way of example not limiting the scope of the present invention.

DETAILED DESCRIPTION

[0013] According to the drawings the wall (1) being the object of this invention is a prefabricated wall and makes up a bridge (2) being arranged in a transversal arrangement in a swimming pool (3) and having at each of its ends a respective bearing (4) and (5) resting on the respective lateral edge (6) and (7) of the swimming pool.

[0014] Two wheel pairs (8) and (9) (Fig. 3) are fitted to each of these bearings and run on corresponding rails (10) (Fig. 6), the wheels of each pair being divergently tapered at their periphery (11) in correspondence with the tapers (12) of the rails.

[0015] The bridge (2) adapts at its ends to the swimming pool vessel by means of resilient edges (13) and the shiftable wall is made up by a framework (14) being formed by three lengths (a), (b) and (c) being joined together and at their front and back faces comprising grid panels (15) (Fig. 4).

[0016] The bridge ends being formed by the bearings (4) and (5) being provided with the wheel pairs (8) and (9) are each linked to a respective rope (16) and (17) (Fig. 5) forming a respective loop being guided by pulleys (18), said ropes being driven by a motor (19) (Fig. 7), the ropes being linked at their ends to a drum (20) having a helical periphery and being driven by the motor (19) through transmissions by means of sprockets and the corresponding sprocket chains (21), said drum being shifted on the screw spindle (22) and thus allowing the ropes to always be wound on the drum as per an arrangement being perpendicular to the axis of this latter.

[0017] The fact of the framework being made up of several lengths facilitates its transportation, said lengths being assembled together with no need for special machinery since they are joined together by means of screw fastening.

[0018] The motor unit will comprise means being such as to assure a synchronised shifting of the two ends of the bridge, this latter being provided with the proper safety devices that will deactivate the motor when the bridge during its shifting travel comes into juxtaposition to one of the ends walls of the swimming pool, or when there is an anomaly in its operation.

[0019] The invention can within its essentiality be put into practice in other embodiments only in detail differing from the one having been described above only by way of example, said other embodiments also falling within the scope of the protection being sought. This shiftable wall can hence be manufactured in any shape and size, with the best suited means and materials and with the most convenient accessories, and its integrating elements can be replaced with others being technically equivalent, all this falling within the spirit of the appended claims.
