  • Patent number: 5472272
    Abstract: A drawer rail assembly having at least an outer rail, an inner rail, and ball bearings enabling relative extension therebetween, said rails having vertical legs and generally horizontally extending, arcuate, radiused legs forming bearing races. At least the lower, generally horizontally extending leg of the outer race has an integral buttress leg or extension which protrudes at an obtuse angle from the arcuate portion and has two sections, namely an intermediate section at an obtuse angle to the end of the arcuate portion, and a terminal section at an obtuse angle to the intermediate section.

  • Patent number: 5411333
    Abstract: A drawer slide assembly comprising two or more channel pieces is fabricated from both plastic and metal materials. Specifically, the channel pieces are made up of formed steel and certain individual components such as stops, cushions and ball retainers are made of plastic. The invention behind the present concept is usage of detents, tabs and projections to retain the plastic components in their positions while maintaining the functional integrity of these individual items as they function within the drawer slide.

  • Patent number: 5316389
    Abstract: A drawer slide stop lever mechanism comprises a stop lever that is fixed to an inner channel member between the ends of the channel, and at one end of the stop lever, with the other end being free to resiliently flex from an at rest position to an actuated position. This stop lever includes a lever trigger, and a middle portion having a block with stop faces. Corresponding to the stop faces are faces found on opposing stop means of the other intermediate rail.

  • Patent number: 5069408
    Abstract: A shelving assembly having vertical standards and cantilever brackets, and an elongated generally U-shaped cover over each standard. The cover flanges laterally stabilize the bracket. The brackets have V-shaped upper recesses interfitting with slotted hemispherical shelving mounts fitted in the upper edge recesses of the brackets, each mount having a tapered slot configuration complementary to the recess configuration, and having an upper adhesive pad and a vertical jack for temporarily holding a shelf up off the adhesive. The jacks are shiftable down under limited predetermined force to lower the shelf onto the adhesive for anchoring.

  • Patent number: 5004202
    Abstract: A shelving assembly having vertical standards and brackets thereon suspending shelves therebetween by telescopic mounting connectors telescopically fitted into and projecting from openings as in reinforcing beams recessed into the bottom of the shelves. The mounting connectors extend into openings in the brackets. These openings are in alternate pairs to allow the shelf to be in either of two positions, preferably horizontal or tilted diagonally. The connectors have peripheral grooves configured to interengage with the plate type brackets, there being three such grooves so they can support one end of one shelf on a bracket or the adjacent ends of two shelves on a common bracket. Glass shelves can be mounted on these book end brackets using socket shelf mounts having a receiving socket in a body, an outer shelf support surface, and a resilient clip for attachment to the shelf.

  • Patent number: 5004201
    Abstract: A shelving assembly having vertical standards and cantilever brackets, and an elongated cover over each standard. The cover has slots coinciding with the standard slots but of greater length. The cover webs between the slots are shorter than the standard webs. The bracket holds the cover vertically in place. The cover flanges laterally stabilize the bracket. The brackets have lugs that extend through slots on the cover and slots on the standard, and engage behind webs on the standard between the slots. The spaces between the lug front faces and the rear edge of the bracket have receiving portions of a width to receive both standard webs and cover webs. The bracket rear edge also has abutment portions adjacent the bottom of the bracket engaging exposed standard web surface not covered by cover web.

  • Patent number: 5002248
    Abstract: A shelving assembly having vertical standards and brackets thereon suspending shelves therebetween by steel mounting pins projecting from channels in reinforcing beams recessed into the bottom of the shelves. The mounting pins extend into openings in the brackets. These openings, when in the form of recesses in the upper edge of the brackets, are configured with an overhand lip to prevent shelf tipping. These openings, when in bookend brackets are in alternate pairs to allow the shelf to be horizontal or tilted diagonally.The pins have a steel core, preferably jacketed with polymer having an integral peripheral flexible fin for a friction fit in the channels. These pins have peripheral grooves configured to interengage with plate type brackets. The pins have three such grooves so that they can serve to support one end of one shelf on the bracket or the adjacent ends of two shelves on a common bracket.

  • Patent number: 4966343
    Abstract: A shelving assembly having vertical standards and cantilever brackets, an elongated generally U-shaped cover over each standard, its legs being resiliently biased toward the standard, and there being a space extending in from the apex of the cover and straddled by flanges which integrally join a cross piece forming webs and vertically spaced slots generally coinciding with slots in the standard. The legs hold the cover on the standard. The bracket holds the cover vertically in place. The cover flanges laterally stabilize the bracket. Caps and collars project from the ends of the standards. The brackets have slotted shelving mounts fitted in upper edge recesses of the brackets, each mount having an upper adhesive pad and a vertical jack for temporarily holding a shelf up off the adhesive. The jacks are shiftable down under limited predetermined force to lower the shelf onto the adhesive for anchoring. A wire clip for guiding an electric wire is attachable to the standard by lug engagement.

  • Patent number: 4765699
    Abstract: The specification discloses a lift-out drawer slide having a lock to positively prevent accidental or inadvertent removal of the drawer from the cabinet. As is conventional in lift-out slides, the drawer rail can be vertically cocked with respect to the supporting rail to bypass the stop mechanism and remove the drawer. The present slide includes a movable lock which can be positioned within the clearance space between the rails to prevent relative cocking of the rails and thereby prevent bypassing of the stop mechanism.
