Definitions

  • Mechanics' cabinets and tool cabinets typically are fabricated from sheet metal and include a cabinet enclosure with drawers. Examples of mechanics' cabinets are depicted in U.S. Pat. No. 4,681,381 and U.S. Pat. No. 5,435,640 which are incorporated herewith by reference in their entirety.
  • a locking system is provided.
  • the locking system will normally include a key actuated mechanism which enables locking of the drawers in a closed position. Actuation or release of the key operated mechanism is necessary in order to release or unlock the drawers.
  • the present application discloses embodiments of drawer latches.
  • the disclosed drawer latches may be used in a wide variety of different applications, including a sliding drawer assembly.
  • the present application contemplates a drawer latch that may be provided to retain one or more drawers in a closed position unless positively opened by the user of the cabinet. This may be a desirable feature in a cabinet construction in order to preclude accidental opening of drawers, without requiring locking of the drawers in the closed position, such as with a key- operated locking mechanism. Maintaining the drawers in a closed position also inhibits the drawers from opening when the cabinet is, for example, being transported from one location to another.
  • a sliding drawer assembly includes a cabinet frame, a drawer, a drawer handle, and a catch member.
  • the drawer is slideably coupled to the cabinet frame.
  • the drawer includes a front wall and a top wall.
  • the drawer handle has a pivot wall that has an edge that is pivotable on or about the drawer top wall to allow the drawer handle to move between a drawer retention position and a drawer release position.
  • the catch member is coupled to the cabinet frame to maintain the drawer in the closed position.
  • the catch member is decoupled from the cabinet frame to allow the drawer to move from the closed position to an open position.
  • a sliding drawer assembly in another embodiment, includes a cabinet frame, a drawer, a pull handle, a drawer release handle, and a catch member.
  • the drawer is slideably coupled to the cabinet.
  • the pull handle is fixed to a front wall.
  • the drawer release handle has a pivot wall that is pivotable on or about an edge of the drawer front wall to allow the drawer release handle to move between a drawer retention position and a drawer release position.
  • the drawer release handle may be retained to the drawer by the pull handle.
  • a catch member is connected to the drawer release handle. When the drawer release handle is in the drawer retention position and the drawer is in a closed position, the catch member is coupled to the cabinet frame to maintain the drawer in the closed position. When the drawer release handle is in the drawer release position and the drawer is in the closed position, the catch member is decoupled from the cabinet frame to allow the drawer to move from the closed position to an open position.

Abstract

L'invention concerne un ensemble tiroir coulissant qui comporte un bâti d'armoire, un tiroir, une poignée de tiroir, et un élément de préhension. Le tiroir est couplé coulissant au cadre d'armoire. Le tiroir comporte une paroi avant et une paroi supérieure. La poignée de tiroir a une paroi pivot dont un bord pivote autour de la paroi supérieure du tiroir pour permettre à la poignée du tiroir de se déplacer entre une position de retenue du tiroir et une position de libération du tiroir. Lorsque la poignée est en position de retenue du tiroir et le tiroir en position de fermeture, l'élément de préhension est couplé au cadre de l'armoire de manière à maintenir le tiroir en position de fermeture. Lorsque la poignée est en position de libération du tiroir et le tiroir en position de fermeture, l'élément de préhension est libéré du cadre de l'armoire, ce qui permet au tiroir de se déplacer de la position de fermeture à une position d'ouverture.
