Filed:

Jul 27, 2001

Appl. No.:

09/916816

Inventors:

Robert A. Andersen - Glenview IL 60025

International Classification:

A47K 1310

US Classification:

42461, 42463

Abstract:

A closure apparatus and a method of installing the same are provided. The closure apparatus is adapted to mount to a toilet having a cover, a bowl ledge and a flush mechanism. The closure apparatus includes a mounting bolt having an opening extending therethrough and a rod disposed within the opening of the bolt. The apparatus also includes a spring that is adapted to be deformed by the rod to thereby bias the rod and a lever movable with respect to the mounting bolt. A latch release mechanism coupled to the lever is also included. Upon flushing the toilet when the cover is open, and when the closure apparatus is mounted on the bowl ledge, the latch release mechanism causes the latch point of the lever to move with respect to the mounting bolt and allows the spring to move the rod, which pushes the cover, to thereby close the cover.

Appl. No.:

11/182082

Inventors:

Robert Andersen - Barrington IL, US

International Classification:

F04B 53/00
F04B 39/00

US Classification:

417437000, 417572000

Abstract:

A method for assembling a piston on a rod, and resultant piston and rod assembly, uses one or more lock rings that are mechanically deformed radially inwardly into respective locking grooves in the rod, thereby axially locking the lock ring to the rod. The lock ring can function as an axial stop for the piston or can be formed integrally with the piston. The method of assembly minimize unwanted strains and stresses in the piston and rod, while providing a secure and durable joint between the piston and rod.

Inventors:

Robert Andersen - Glenview IL, US

International Classification:

A47K 13/10

US Classification:

004246100

Abstract:

A toilet assembly that includes a bowl, a toilet seat member mounted on the bowl for movement between raised and lowered positions, and a tank mounted on the bowl. The tank is adapted to contain water for flushing the toilet and has a flushing apparatus for causing the water in the tank to flow into the bowl. The toilet assembly also includes a hydraulic closure apparatus mounted on the toilet. The apparatus includes a member movable relative to the toilet and engageable with the seat member such that movement of the member in one direction moves the seat member toward the lowered position. Movement of the seat member toward the raised position moves the member in an opposite direction. The apparatus also includes a cylinder and a piston slidable inside the cylinder. The piston divides the cylinder into first and second chambers and is connected to the member such that movement of the member in the opposite direction moves the piston in the direction minimizing the volume of the second chamber. The apparatus further includes a spring positioned in the second chamber. The spring is compressed by the piston when the piston moves in the direction minimizing the volume of the second chamber. The apparatus also further includes a conduit having one end in communication with the second chamber and a second end positioned in the water in the tank. The toilet assembly further includes a valve arrangement for closing the second end of the conduit when the tank is relatively full of water and for opening the second end of the conduit when the toilet is flushed.

Robert A. Andersen - Glenview IL, US

International Classification:

A47K 13/12
A47K 13/14

US Classification:

4240, 42421

Abstract:

A closing apparatus is provided for automatically closing a toilet seat assembly adapted for mounting to a top ledge of a toilet bowl. Embodiments of the closing apparatus include an actuator for automatically rotating the toilet seat assembly between open and closed positions. The closing apparatus may also include one or more dampers for resisting the rotational movement of the toilet seat assembly so as to extend the closing rotation of the toilet seat assembly over a desired delay period. In other embodiments, the respective centers of gravity of a seat and a lid of the toilet seat assembly may be positioned with respect to a hinge axis of the toilet seat assembly in a manner that causes the seat or the seat and the lid to automatically close via gravitational torque when released in the open position. The closure apparatus may also include a simplified latch mechanism for selectively restraining the toilet seat assembly in an open position.

Robert A. Andersen - Glenview IL

International Classification:

B08B 900
F28G 900

US Classification:

141 7

Abstract:

An apparatus and method for changing the antifreeze in a vehicle requires only a garden hose and opening of the radiator cap. Water from the hose is utilized to prime a conduit for siphoning used coolant from a side tank radiator and for refilling the radiator. By operating the vehicle with fresh water in the radiator, coolant remaining in the system is mixed with the water, and repeated drainings decrease the remaining used antifreeze by about one-half each time. After removal of the desired amount of antifreeze, new antifreeze may be placed in the radiator.

Abstract:

A port mounted fluid control valve construction (18) is mounted to a pneumatic cylinder (10) through the first port (31) and second port (37) of the cylinder. The construction includes a removable valve body portion (22) which is detachable from a manifold portion (20). A tube (34) extends from the manifold portion to an adapter body (36). The manifold portion includes a first inlet (42) which extends to a first outlet (50) through a first passage (52). An ear (44) extends in the first passage. A spud fitting (100) which includes cutouts (110) which enables fluid to pass therethrough, is mounted in the first port of the cylinder. The spud fitting includes a threaded opening which accepts a fastener (102). The fastener extends through ear (44) and holds the manifold adjacent the cylinder. The adapter body includes first aperture (122) which is in fluid communication through the adapter body with the tube.
