Abstract:
A tolerance ring has a band with outwardly extending corrugated protrusions forming waves that engage an outer surface of a shaft. At one end of the tolerance ring is an inwardly flared guide surface extending axially and radially from the band. The guide surface acts as a tapered entrance to a bore of a housing to assist during assembly.

Abstract:
The present invention provides a protective sports helmet for a wearer engaged in a contact sport, such as football. The helmet includes a shell having a front region, a rear region, two side regions, and an ear flap depending from a side region. A jaw flap extends forwardly from each ear flap, wherein the jaw flap overlies an extent of a mandible of the wearer. The shell also includes a raised central band that extends from the front region across the crown to the rear region. The central band has lower side portions that extend from the rear region towards the side region of the shell and terminate proximate an ear opening in the shell. The central band has a width defined by a pair of opposed sidewalls that extend transversely from an outer surface of the shell. The shell also includes a first plurality of vent openings aligned along a first side of the raised central band and a second plurality of vent openings aligned along a second side of the band.
Abstract:
A system for securing a cover to a panel door of a recreational vehicle, the cover typically being a tent, as well as the resultant living space extension for the vehicle. An elongated, rigid extrusion is secured peripherally to the panel door, and an elongated channel is shaped to fit in a cavity of the extrusion and be retained in place, with the channel being stitched to the bottom skirt of the cover. With the channel engaged on the extension, the cover is retained essentially permanently in engagement on the panel door.
Abstract:
A releasable squeegee assembly for coupling to a surface maintenance machine and including a compliant bushing and an over-center lever attached to a pull rod and compliant spring. The compliant bushing is compressed via said over-center lever with said compliant spring providing a spring force. A bushing sleeve is provided to limit the degree of compression of said compliant bushing by the over-center lever. A method of coupling a squeegee assembly to a surface maintenance machine is also provided.
Abstract:
A tolerance ring has a band (16) with outwardly extending corrugated protrusions forming waves (2) which engage a surface (8) of the bore (4) in a housing (5). At one end of the tolerance ring is an outwardly flared guide surface (15) extending axially from the band (16). The guide surface (15) acts as an enlarged entrance to the band (16) for a shaft (3) to be mounted in the bore (4) by insertion into the tolerance ring. The use of the guide surface (15) assists assembly and reduces or eliminates particle production. It is also possible for the corrugated portions to extend inwardly, for the guide surface to be inwardly flared, and for the tolerance ring to be mounted on the shaft prior to insertion in the bore.

Abstract:
The present invention provides a face guard for a sports helmet having at least two ear holes. The face guard includes a main body having an arrangement of elongated members. The face guard also includes a pair of quadrilateral projections for securing the face guard to the helmet, wherein the projections are integral with and extend from the main body. The projections are positioned below the ear holes in the helmet when the face guard is secured to the helmet. Also, the projections are positioned adjacent a lower edge of the helmet when the face guard is secured to the helmet. The projections are positioned below a rear lower edge of the helmet when the face guard is secured to the helmet. Each projection has first and second vertical members that are configured to engage a connector that secures the face guard to the helmet. Furthermore, each projection includes a first and second substantially horizontal members that, when combined with the first and second vertical members, define a rectangle or a trapezoid.
Abstract:
A new football helmet includes: a jaw flap attached to the ear flap of the helmet, and the jaw flap overlies the sides of the lower jaw of football player; and a face guard connector which includes a shock absorbing member.
Abstract:
A flexible drive shaft extension for hand tools comprises serially nested, socket-ended shaft components of polygonal cross-section which have freedom of universal movement from axial alignment limited to about five degrees of arc and which are forcibly retained in coupled connection within a sleeve by spring biasing.
