Abstract
A net for removing debris is mounted on a frame which is extendable across the width of a swimming pool. The frame has a rounded or ball-type element at each lower end which rotates about an axis to facilitate travel and to protect the swimming pool surfaces from damage as the swimming pool cleaning device is moved through the water during a cleaning operation. Handles are provided for pulling the net through the water by persons on opposing sides of the pool. The pool may be cleaned in a single pass across the length of the pool. The net may be completely or partially rolled up about at least one of the side members of the frame.
Claims20
A swimming pool cleaner for removing debris from a swimming pool comprising:
- a) a net catching floating and submerged debris in a swimming pool,
- b) a frame upon which said net is mounted, said frame comprising upper and lower substantially horizontal members which are connected to first and second substantially vertical side members,
- c) a weight for maintaining said net in a submerged position while it is moved through water contained within the swimming pool during a pool cleaning operation, and
- d) rounded elements rotatably mounted to said frame to facilitate travel of the net through the water and to protect the pool from damage by the frame.
A buoyant swimming pool cleaner for removing debris from a swimming pool comprising:
- a) a net for catching floating and submerged debris in a swimming pool,
- b) a frame upon which said net is mounted, said frame comprising a buoyant upper member,
- c) a weight for maintaining said net in a submerged position while it is moved through water contained within the swimming pool during a pool cleaning operation, and
- d) rounded elements rotatably mounted to said frame to facilitate travel of the net through the water and to protect the pool from damage by the frame.
A swimming pool cleaner for removing debris from a swimming pool comprising:
- a) a net for catching floating and submerged debris in a swimming pool.
- b) a frame upon which said net is mounted,
- c) a weight for maintaining said net in a submerged position while it is moved through water contained within the swimming pool during a pool cleaning operation, and
- d) rounded elements rotatably mounted to said frame to facilitate travel of the net through the water and to protect the pool from damage by the frame, said rounded elements being rotatably so that upon movement of the net through the water the rounded elements can rotate upon contacting the side walls of the pool.
A swimming pool cleaner for removing floating and submerged debris from a swimming pool comprising a foldable net having upper and lower flexible cord-like members, rigid side members, rounded elements attached to said side members for rotation about a vertical axis so that upon movement of the net through water in the pool during a cleaning operation the rounded elements can rotate upon contacting the side walls of the pool to prevent damage to the pool walls, and handles for pulling the net through the water by persons on opposing sides of the pool.
