  • Patent number: 11691570
    Abstract: A telescoping roof rack system is described. Embodiments of the telescoping roof rack system can include, but are not limited to, roof rack assemblies, crossbar assemblies, a canopy, and combinations thereof. The telescoping roof rack system can be implemented to provide an awning proximate a side of a vehicle. The telescoping roof rack system can provide protrusions extending out an end of the crossbar assemblies such that no additional components are needed to provide the awning.

  • Publication number: 20100192417
    Abstract: A modular snow travel system for common footwear includes a first traction component which may be an overboot. The first traction component includes at least one traction cleat having latch, such as an exposed hook portion, for engagement with a snowdeck. The engagement is effected by a releasable locking mechanism on the snowdeck. The releasable locking mechanism includes a transversely movable slider and a longitudinally movable slider having contacting cam faces. The lateral position of the transverse slider determines the longitudinal position of the longitudinal slider so that the longitudinal slider could be moved longitudinally to and from a position where a catch on the longitudinal slider is engaged in the hook portion or is disengaged from the latch of the traction cleat.

  • Publication number: 20030052473
    Abstract: A cleated overshoe and snowshoe with a binding for accepting the overshoe. The overshoe includes a fastener for tightening the overshoe around a shoe. The overshoe also has a sole with one or more claws. The claws have apertures for receiving tabs or similar protrusions. The claws fit into a step-in binding on the snowshoe. The snowshoe has an outer frame, a decking, and a decking strap and the step-in binding is secured to the decking strap. The binding has a connection point for coupling each claw of the overshoe to the binding. In one embodiment, the binding also includes a base plate, a lift mounted to the base plate, a heel plate mounted to the lift, and a latch tab mounted to the heel plate. The latch tab is movable between a locked position and an unlocked position. In the locked position, the latch tab secures the claws of the overshoe in a position where the claws are coupled to the connection point.

  • Patent number: 4342442
    Abstract: Mold for injection molding battery containers which include a plurality of thin resilient ribs integral with and projecting at acute angles from the inside walls thereof into the cell compartment(s) to hold the battery's innards therein. The core of the mold includes a mandrel defining the cell compartment. The mandrel has dovetail-like mortises therein and complementary-shaped ejector bars reciprocally slideable within the mortises between retracted and extended positions to facilitate stripping the container from the core. The rib-forming portion of the mold cavity is formed in the side walls of the ejector bar. The ejector bars travel with the container during at least part of the ejection cycle so as to free the rib from the rib-forming cavity without untoward resistance or permanent deformation of the ribs.

  • Patent number: 4328945
    Abstract: Mold for injection molding battery containers which include a plurality of thin resilient ribs integral with and projecting at acute angles from the inside walls thereof into the cell compartment(s) to hold the battery's innards therein. The core of the mold includes a compartment-shaping mandrel which in turn includes ejector bars reciprocally slideable within complementary-shaped mortises in the mandrel. Rib-forming cavities are formed in the side walls of the ejector bars. Lips at the distal ends of the ejector bars project toward the mortise walls to produce undercuts at the bases of the ribs which in turn result in the formation of ribs which are detached from the bottom of the container.
