Abstract
Abstract A covering arrangement for swimming pools or similar open areas in which a flexible cover has one end attached to a drum, and which may be wound onto the drum or rolled off from the drum. A reversible motor operates the drum for unwinding the cover when the motor operates in one direction of rotation. In the reverse direction of the motor, the cover is rolled off from the drum. A carriage serves to carry the drum which is provided with transport mechanisms on each side. A coupling arrangement connects the motor to the transport mechanisms when the motor rotates the drum for the purpose of unwinding the cover from the drum. When, on the other hand, the cover is to be wound onto the drum, the motor is connected by the coupling arrangement to the drum.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
150 words
A covering arrangement for open areas comprising, in combination, flexible cover means; winding drum means attached to one end of said flexible cover means, said flexible cover means being windable on said drum means; reversible motor means linked to said drum means for unwinding said cover means from said drum means in one direction of said motor means, siad cover means being wound onto said drum means in the reverse direction of said motor means; wagon means for carrying said drum means and transporting said drum means; drive means on each side of said drum means; and coupling means connected between said motor means, drum means and drive means so that said motor means is connected to said drive means when said motor means rotates in said one direction, said motor means being connected through said coupling to said drum means when said motor means rotates in said reverse direction.
Claim 2
Dependent Claim
150 words

Claim 9
Dependent Claim
43 words
the arrangement as defined in claim 4, wherein the outer diameter of said wheel means is substantially larger than said drum means with said cover means wound on said drum means; and including compensating means for compensating for the difference of said diameters.
Claim 10
Dependent Claim
34 words
The arrangement as defined in claim 8, including slip clutch means connected to said coupling means, said slip clutch means and said coupling means being connected between said drum means and said wheel means.
Claim 11
Dependent Claim
28 words
