  • Patent number: 5419435
    Abstract: A sharps disposal system providing a frame and a container having an opening and being selectively mountable to the frame. A lid is pivotally attached to the frame and is selectively movable into engagement with the container when the container is mounted to the frame. Engaging the container with the lid closes the opening except for an aperture through which sharps can be inserted into the container but which impedes insertion of human hands. Engaging the container with the lid also impedes removal of the container from the frame. The system employs a means for selectively locking the lid into engagement with the container. The system further provides a cover for selectively sealing said opening.

  • Patent number: 5348356
    Abstract: A hidden, releasable latch for a molded plastic enclosure having a first panel abutting a second panel along a seam. The first panel has a pressure bump on its inside surface a first distance from the seam, and a projecting tang on its inside surface at a further distance from the seam. The second panel has a tab from its inside surface projecting inside, parallel and spaced from the inside surface of the first panel, the tab contacting the pressure bump, and capturing the projecting tang in a hole within the tab. The tab is flexible enough for slight deflection during the capturing of the tang by the hole during an assembly process, and the releasing of the tang by movement of the tab from pressure from the pressure bump during a disassembly process.

  • Patent number: 4730731
    Abstract: A unitary child-resistant container for pills and the like includes a rectangular tray-shaped body member to which a top closure member is connected by an integral hinge. The top closure member includes a front wall that is normally latched to the front wall of the body member by a latch device that is released by a release button that extends outwardly from the deformable front wall of the body member through a corresponding opening contained in the closure member front wall. Consequently, opening of the container requires the simultaneous depression of the release button and the application of a vertical lifting force on the top closure member. Stiffening ribs may be provided on the underside of the top closure member for frictional engagement with the inner surfaces of the body member side walls, thereby to further retain the closure member in the closed position. Preferably, the container is molded in one step from synthetic plastic material.

  • Patent number: 4541595
    Abstract: In an aircraft having a pressure window mounted in the hull, an interior window assembly is removably mounted in an interior wall spaced from the hull. The interior window assembly is in register with the pressure window to enable occupants of the aircraft to view the outside. The interior wall has an opening formed therein to accept the interior window assembly and the portions of the wall surrounding the opening are biased toward the interior of the aircraft. The interior window assembly includes a windowpane mounted in a frame. The frame includes a flange that overlies the inboard surface of the portions of the wall surrounding the opening, and the bias of the wall portions is exerted on the flange. A constraint means is affixed to the hull of the aircraft and releasably engages the frame to constrain the frame from inboard movement. The bias force of the wall portions and the constraint means cooperate to hold the window in place.

  • Patent number: 4501378
    Abstract: A latch unit for releasably securing a plastic lid to a tank-like container or for releasably securing another covering over the container. The container may be the tank of an electric vacuum cleaner. There are a plurality of the latch units spaced along the edge of the lid or covering and engageable with a bead around the open end of the tank. Each latch unit includes a cage at the edge of the lid or of the covering and includes a latch element molded of resilient plastic material. One end of the latch element protrudes from the cage and is hand engageable for moving the element between releasing and holding positions. The other end of the element is provided with a hook that engages a cage formation to form a pivot for the element. A normally bowed intermediate section of the element connects opposite ends of the element, and is stressed to provide a biasing force that holds the element mounted to the cage.

  • Patent number: 4455049
    Abstract: A simple latch assembly suitable for a lifting seat cushion in a motor vehicle comprises a latch member (9) in the form of a wire having two lobes (14, 15) each extending approximately in radial planes from a common axis (16). One lobe (14) engages a catch (2); the other (15) can be manipulated. The ends (10, 11) of the wire are fixed at spaced points (12, 13) so that rotation of either lobe (14, 15) about the common axis displaces the other and generates a restoring force in the loop biasing the lobes towards their original positions.

  • Patent number: 4407538
    Abstract: A latch mechanism useful for belt buckles, door latches, etc., includes an endless member in the form of a frusto-conical or frusto-spherical band of spring-like material which can be snapped between two stable positions. In one position the rim of the band is disposed on one side of a reference plane defined by the outer rim; in the other position the inner rim is on the opposite side of that plane. An integral tongue projects from one rim of the band and is positionally slaved thereto to assume first and second orientations depending upon the band position. The band is secured to one of two members to be latched, the second member having a keeper for receiving the tongue and a portion of the band, precluding relative movement between the two members. A keeper surface abuts the distal edge of the tongue in one stable band position such that movement of the band out of the keeper is resisted by the abutting force of the surface applied longitudinally to the tongue.

  • Patent number: 4344646
    Abstract: A detachable latch for a container is arranged to snap fit into a latch pocket and operate with minimal or no frictional interference in releasing a projecting bolt member from a closure position wherein it projects through a slot in the container cover. In a first embodiment, the base of the latch member abuts the pocket wall and is restrained from upward displacement by a wing-slot engagement. A retainer blade projects forwardly from the upper half of the latch to a location above a retainer shelf of the container body to preclude downward displacement of the latch. At least one nub projects upwardly from the shelf to provide minimal contact with the underside of the blade if the blade is inadvertently lowered into contact with the shelf. To open the container, the latch is flexed about its base by pushing the upper part of the latch into the pocket, thereby removing the bolt at the top of the latch from the cover slot.
