Abstract: Connecting hardware for furniture parts, particularly of panel-shaped components of easily disassembled furniture. The connecting hardware includes a bolt which protrudes from one furniture part and can be introduced into a recess in the second furniture part. The bolt is held in a connecting position by a tensioning element provided in the recess and which engages the free end of the bolt, the bolt being held in a fastening bushing inserted in the first furniture part. The end section of the bolt is offset eccentrically to the center axis of the bolt and is disposed rotatably in an associated accommodating opening of the fastening bushing. The accommodating opening for holding the end section in turn is offset by the same amount eccentrically to the external diameter of the fastening bushing. The eccentricity of the end section and of the associated accommodating opening is selected so that the accommodating opening extends to the outside with formation of a slot-like opening in the fastening bushing.

Abstract: The present invention is a fitting for the adjustable-height mounting of drawers on the runner rails of drawer slides, which support them on the bottom. On the runner rail of each drawer slide a slider is provided with a bearing surface facing the drawer bottom, and can be shifted parallel to the runner rails by a given amount. The slides are inclined, however, such that the bearing surface of the slider will be substantially flush with the drawer bottom or even below the drawer bottom when the drawer is supported on the runner rail in the properly installed position. But in the other end position the slider is shifted upward by the amount desired for the adjustment.

Abstract: An automatic pull-in mechanism for drawer guides consists of a guide rail and a runner rail, which are made longitudinally displaceable relative to one another by rolling bodies. On the guide rail there is disposed a component that can toggle between two end positions and is biased bistably toward the toggle end positions by a spring system, and has an open-ended slot for a projection projecting downward from the runner rail. The projection and the toggling component are so disposed relative to one another that upon a displacement of the runner rail from the drawer-open position to the drawer-closed position, as the projection approaches the latter it enters into the slot and then, after passing over the dead center of the toggling component, it is carried resiliently by the slot into the drawer-closed position.

Abstract: The invention relates to a carcase-related part of a cabinet hinge, which is an elongated, channel-shaped supporting arm, releasably fastened on the mounting plate by a catch mechanism. The catch mechanism has at the outer end of the mounting plate and supporting arm, a hanger device enabling the supporting arm to tilt relative to the mounting plate. At the inner end of the supporting arm where it straddles the mounting plate, two tongues are provided which can be flexed resiliently parallel to the cabinet wall surface. Each tongue bears a latch section which can be engaged in an associated catch in the mounting plate. The hanger coupling of the supporting arm and mounting plate has an at least partially spherical holding head which is introduced into a slot conforming approximately to the shape of the holding head.

Abstract: An over-center hinge for cabinet doors with a door-related hinge part in the form of a recess-mounting cup in which one end of each of two links is journaled whose other ends are journaled on a jamb-related hinge part in the form of an elongated supporting arm. On the side of the inner link facing the outer link a cam is articulated with its free end facing the supportring arm and is urged by a spring inserted between the cam and the pivot eye of the inner link against a counter-surface formed by a section of the inner wall of the supporting arm such that its face forces the hinge resiliently into the closed position upon passing a dead point in the closing movement. The section of the wall of the supporting arm that forms the counter-surface is provided at least in the surface area cooperating with the cam with a smooth, wear-resistant and friction-reducing surface.

Abstract: Hinge for hanging a door on the facing of a cabinet. The carcase-related part of the hinge, in the form of an elongated door-supporting arm, can be adjustably fastened on a mounting plate preinstalled on the inside surface of the facing, while its free end, which is angled toward the door, is coupled to a door-related member in the form of a hollow cup by means of a four-joint mechanism. The door-supporting arm is fastened to the mounting plate through an intermediate piece which is disposed in its rearward end portion between the supporting arm and the mounting plate and is mounted releasably on the mounting plate and on the supporting arm of adjustment by a certain amount lengthwise of the supporting arm. The intermediate piece and the supporting arm are coupled together by a threaded spindle (84) which is in threaded engagement with one of the coupled parts while it is connected to the other part in such a way that it is rotatable, but non-displaceable lengthwise relative thereto.

Abstract: Cabinet hinge whose jamb-related part in the form of an arm can be fastened at selectable positions along the length of a mounting plate attached to a jamb on a cabinet carcase by sliding it onto the mounting plate and then tightening a screw. The mounting plate has a spring catch element which as the installation of the arm begins snaps into a corresponding cutout or recess in the arm of the hinge and thus screws it against accidental withdrawal from the mounting plate, without interfering with its further movement for the purpose of a longitudinal adjustment of the arm on the mounting plate. The spring catch has a prolongation brought out of an opening in the cabinet-interior end of the mounting plate, and this prolongation can be shifted resiliently such that the cooperating abutments of the spring catch and opening become disengaged from one another.
