Claims
- 1. A device for lifting a person from a pool comprising:
- a base mount with a shaft extending along a longitudinal axis; a column extending from the base mount along the longitudinal axis and selectively rotatable with respect to the base mount; a drivable belt and a catch belt;
- belt support mounted on a top end of the column, said belt support including a housing;
- means to hold a person including a lifting arm having a first end attached to a person holding element and a second end attached to a device which is fixed to the drivable belt and to the catch belt;
- said drivable and catch belt extending in parallel and moving synchronously along the longitudinal axis of the column during the lifting and lowering operation of a person; and
- said catch belt arresting movement when the speed of lowering of the person holding element exceeds a predetermined value.
- 2. The device according to claim 1, wherein the column includes a tube-shaped bottom end, said bottom end cooperating with the shaft to enable column rotation.
- 3. The device according to claim 2, including locking means to prevent column rotation relative to the base mount.
- 4. The device according to claim 1, further including a battery operated drive means for operating the drivable belt.
- 5. The device according to claim 4, wherein the person holding element is arranged on a first side of the column and the drive means having control elements are mounted on an opposite side.
- 6. The device according to claim 4, wherein the column includes a battery receptacle near the base mount and the drive means includes an emergency off switch to disable operation.
- 7. The device according to claim 4, further including a switch actuatable by the drivable belt, said switch means being kept in the ON position as long as the drivable belt is under tension, but changing to the OFF position when not under belt tension, so as to render the drive means inoperative.
- 8. The device according to claim 1, wherein the column includes U-shaped guides, the drivable belt is drawn through a first U-shaped guide and the catch belt is drawn through a second U-shaped guide, the first and second U-shaped guides being parallel to each other, said drivable belt and said catch belt are fastened in their individual guides to a first and second securing attachment contained in each of the corresponding guides, first and second elements extend through the U-shaped guides and are connected to the means to hold a person.
- 9. The device according to claim 8, wherein the first and second securing attachment are formed as shuttles capable of running inside the first and second U-shaped guide.
- 10. The device according to claim 4, wherein the drivable belt acts on a switch so that when the drivable belt is under tension, the drive means is supplied with battery power and when the drivable belt is not under tension, the battery power supply is cut off.
- 11. The device according to claim 2, including locking means to prevent column rotation relative to said base having a bolt connected to a lever, a sleeve with an internal thread connected to the column and a lever for turning the bolt to press against the base mount shaft until rotation is prevented.
