  • Patent number: 5421648
    Abstract: A drawer guide including a drawer rail for connection to a drawer, a carcass rail for connection to a carcass and a center rail which engages the drawer and carcass rails in a load transmitting relationship. Engagement with the drawer and carcass rails is by means of upper and lower carriages each of which include a plurality of rollers. In order to obtain synchronous displacement of the center rail during displacement of the drawer rail, there is provided a closed loop cable or chain traction means which runs over guide rollers arranged on opposite ends of the center rail. The upper run of the traction means is connected to both ends of the upper carriage, while the lower run of the traction means is connected to both ends of the lower carriage.

  • Patent number: 5419026
    Abstract: A tool for anchoring a housing barrel where in the barrel has a plurality of expandable claws, the tool comprising a support plate moveable axially and a plunger associated with the plate moveable therewith. The plunger has a plate engaging in and a tapered point. The tapered point is arranged to cooperate with an expansion tool consisting of a bowl cage, and a number of balls arranged around the cage periphery. Each ball is brought opposite the claw it is to deform. When the tapering point of the plunger penetrates the ball cage, the bails are displaced radially outward and thus deform the claws radially outwardly in the hole of the door section.

  • Patent number: 5406677
    Abstract: A press-fit hinge cup for a hinge is anchored in a recess in a furniture portion, preferably in a door portion, and the anchoring means consists of tabs which project radially outwardly from the side wall of the hinge cup into the material of the peripheral wall of the recess of the furniture portion. In order to avoid excessive weakening of the material of the peripheral wall of the furniture portion and to ensure secure fitting of the hinge cup in the furniture portion respective upper or distal edges of the tabs are located at different distances from the base of the hinge cup relative to each other. As a result these tabs engage in the peripheral wall of the furniture portion along different contour lines in the recess. Additional splay tabs defined by slits positioned substantially perpendicularly to the hinge cup's base and pressed outwardly into the peripheral wall of the recess may be provided. The splay tabs provide additional resistance to twisting of the hinge cup in the recess.

  • Patent number: 5388309
    Abstract: A hinge for insertion in a recess in a furniture portion (e.g. a door) including a press-in cup for engagement with the recess and rotary cup which is engageable with the press-in cup by a rotary action. Pairs of complementarily engageable tabs are provided on the bases of the cups. Further pairs of complementarily engageable engagement tabs are provided on side walls of the cups which provide a camming action tending to urge the cups together as they are engaged. The base of the press-in cup is provided with a resilient detent tongue which springs into place when the cups are connected and resists inadvertent disconnection. Manual depression of the detent permits the cups to be separated.
