The skirt drapes downwardly from the curved rear edge and provides a curvilinear mounting surface to which the scraper element is affixed. The scraper element takes the shape of the curved mounting surface and can be moved along a supporting floor surface in a squeegee type fashion. A second scraper element can be affixed to the front edge of the deck providing a second scraping action. Various attachment structures can be affixed to the upper mounting surface on the deck.Type: GrantFiled: August 6, 1990Date of Patent: December 31, 1991Inventor: Donald L. Mensch

Patent number: 5074027Abstract: A squeegee has a handle consisting of a straight elongate cylindrical member having a pair of elongate blades mounted along one side, flush with one end of the handle and protruding beyond the opposite end. The blades each have a rigid base portion received in one of a pair of channels and a flexible distal portion protruding therefrom for wiping a surface. The blades are integrally formed in a shallow S-shaped cross section and the channels are formed with parallel curved sidewalls conforming to the curvature of a portion of the width of the blade.Type: GrantFiled: April 9, 1990Date of Patent: December 24, 1991Assignee: Hanco, Inc.Inventors: Christopher G. Alviar, Paul E. Furner, David R. Knaub, Terrence K. Jones, Sohrab Vossoughi

Patent number: 4993101Abstract: Tool system (10) advantageously provides tool (12), adapter (14) and extension member (16) successively coupled so that groove (34) mates with rib (44) in the assembled position. Groove (34) and rib (44) are engaged so that tool (12) is axially fixed relative to adapter (14) yet is axially rotatable relative thereto. In preferred embodiments adapter body (36) includes a shoulder (42), and adapter (36) and handle member (20) are correspondingly tapered with increasing radius from top to bottom so that the snapping, engaging action of handle member (20) on adapter head (36) is enhanced when the system (10) is assembled.Type: GrantFiled: October 12, 1989Date of Patent: February 19, 1991Assignee: Mr. Longarm, Inc.Inventors: Robert D. Newman, Sr., Robert D. Newman, Jr.

Patent number: 4977637Abstract: Inside and outside window surface cleaning units contain magnets disposed adjacent to respective base walls. All magnets of the inside unit have the same polarity surfaces adjacent to the base wall. All magnets of the outside unit have all magnets with the opposite polarity adjacent to the base wall so that lateral displacement of the inner and outer units does not cause magnetic repulsion, but rather sustains attraction. A separate outside squeegee unit is provided also having magnets of the opposite polarity adjacent to the base wall.Type: GrantFiled: February 16, 1990Date of Patent: December 18, 1990Inventor: Rodney C. Demers

Patent number: 4941228Abstract: A squeegee or like cleaning appliance, particularly for cleaning window panes and floors having a holder-handle assembly into which can be removably inserted a replaceable cleaning element. The holder is provided with a pivotally mounted fastening apparatus which directly contacts a removably inserted cleaning element that is somewhat rectangular in shape. The fastening apparatus has an open position and a closed position. To remove or insert the cleaning element, the fastener is pivoted to the open position wherein the fastening means does not exert force on the cleaning element. Once the cleaning element has been inserted into the holder, the fastener is moved to the closed position, the fastening apparatus exerting pressure upon the cleaning element. The holder is designed so that the fastener fits snugly when in the closed position. This prevents the cleaning element from sliding in the holder while being used. The fastening apparatus can be opened and closed repeatedly without losing its effectiveness.Type: GrantFiled: December 9, 1988Date of Patent: July 17, 1990Inventors: Daniel J. Belanger, Frank A. Petracek

Patent number: 4926519Abstract: A plastic trowel wherein strength is achieved through use of a blade with a smooth lower side and with handle-retaining members integral with an upper side. Strengthening ribs are disposed on the upper side of the blade. A ribbed handle includes end portions having broad flat areas for contacting the upper face of the blade. Openings in the end portions engage bosses defining the handle-retaining members. The bosses are upset to fasten the handle to the blade. Fastening may be supplemented by cementing or ultrasonic welding the abutting surfaces of the end portions and the blade.Type: GrantFiled: April 10, 1989Date of Patent: May 22, 1990Assignee: Red Devil, Inc.Inventors: Daniel B. Podlesny, Ralph Lopez

Patent number: 4910825Abstract: An attachment for a squeegee includes a resilient mounting member to which a liquid applicator is connected. The liquid applicator preferably comprises a water retentive pad or the like, and the mounting member is preferably formed of a resilient material, such as plastic, which is adapted for connection to the squeegee. The resilient mounting of the pad to the squeegee urges the liquid applicator against the surface being cleaned, and the pad is maintained in a position adjacent the squeegee blade when the blade is placed on the surface.Type: GrantFiled: September 1, 1988Date of Patent: March 27, 1990Inventor: Gary Mauer
