Abstract

The invention relates to a power lead for a swimming pool cleaning robot. Said power lead comprises a rotary connector and a buoyancy means supporting said rotary connector. An upper part of said buoyancy means is a cap shaped to slide under a swimming pool cover, under the effect of a traction exerted by the swimming pool cleaning robot on the buoyancy means through the power lead.

First claim

The invention claimed is:

1. A power lead for a swimming pool cleaning robot, said power lead comprising a rotary connector including a ball joint and a buoyancy means supporting said rotary connector, wherein an upper part of said buoyancy means is a cap shaped to slide under a swimming pool cover, under the effect of a traction exerted by the swimming pool cleaning robot on the buoyancy means through the power lead, and wherein the buoyancy means defines a recess configured to receive the ball joint so as to allow the rotary connector to move with two degrees of freedom.

2. The power lead according to claim 1 , comprising a projection supported by said buoyancy means.

3. The power lead according to claim 2 , wherein said projection can be extracted from said buoyancy means.

4. An assembly for use in a swimming pool, comprising:
a. a first power lead configured for connection to a control device;
b. a second power lead configured for connection to a swimming pool cleaning robot;
c. a rotary connector defining a longitudinal axis and comprising:
i. an upper part (A) defining a ball joint and (B) connected to the first power lead; and
ii. a lower part (A) configured to rotate about the longitudinal axis and (B) connected to the second power lead; and

d. a buoyancy means defining a recess configured to receive the ball joint so as to allow the rotary connector to move with two degrees of freedom.

5. The assembly according to claim 4 , wherein the buoyancy means comprises a smooth, convex cap configured to slide under a cover of the swimming pool.

6. The assembly according to claim 4 , wherein the upper part is configured to be rotationally fixed about the longitudinal axis.
