Abstract: A connector for connecting without tools two panels has a pot-like housing with a radially outwardly protruding expansion sleeve. A clamping lever supported in the housing pivots about a pivot axis between a non-tensioned starting position and a tensioned end position. A tensioning contour extends eccentrically with respect to the pivot axis. A tension bolt has a bolt shaft, with a first bolt end being a first bolt head which is thickened with respect to the bolt shaft and is in the expansion sleeve. A second bolt end being a second bolt head is thickened with respect to the bolt shaft and is arranged inside the housing. The second bolt head is engaged from behind by the eccentric tensioning contour of the clamping lever in the tensioned starting position and is pulled in the direction away from the expansion sleeve. The expansion sleeve is expanded by the first bolt head.

Abstract: A doubling-up fitting includes an expansion sleeve which has a sleeve base with a sleeve base opening and has at least one expansion tab which can be spread radially outward. An inner ring is axially displaceable in the expansion sleeve towards the sleeve base in a tightening direction in order to spread the at least one expansion tab radially outward. A threaded bolt with a screw thread and with a bolt head engages behind the inner ring in the tightening direction. A threaded part has a widened head and can be screwed to the screw thread of the threaded bolt. The opening diameter of the sleeve base opening and the clear opening diameter of the inner ring are each greater than the bolt diameter of the threaded bolt.

Abstract: A doubling-up fitting includes a clamp element with a clamp base and at least two clamp arms rising from the clamp base at its ends. The free clamp ends are angled inward and extend over the clamp base. A rotatably mounted spreading disc is arranged between the clamp base and the free clamp ends. A disc opening leads into a recess in the spreading disc where the diameter is greater than the disc opening diameter. A plurality of outer contour portions spread the free clamp ends radially outward less far in an initial rotational position of the spreading disc than in a final rotational position. An adjusting disc arranged in the recess of the spreading disc has a thread. The outer diameter of the adjusting disc is smaller than the diameter of the recess in the spreading disc and larger than the opening diameter of the disc opening.

Two double-armed levers are connected in an articulated manner about an axis running, in the housing, parallel to the cup axis and which each have an inner lever arm which is arranged in the housing and an outer lever arm which projects outwards beyond the circumference of the housing and is intended for engaging in a surface-area bore in the other part. A handle can be moved from a starting position into an end position and has an actuating element for rotating the inner lever arms in relation to one another such that the two outer lever arms are spread further apart in the end position of the handle than in the starting position.

Abstract: A one-part plastic furniture wall part, in particular a plastic side wall part, includes a lattice-like skeleton structure which is closed toward the outside by an outer wall and is open toward the inside. The skeleton structure has at least one inwardly open recess for receiving a furniture fitting or an electrical component and/or at least one inwardly protruding functional element, in particular a pin.

Abstract: A joining device for parts of furniture and furnishing accessories includes a casing or container body suitable for being inserted in a seat formed in one of the components of the item of furniture to be joined and provided with an expansion bushing externally projecting with respect to a first end or front end of said casing or container body and suitable for engaging with a further seat of a further component of the item of furniture to be joined to the component wherein the casing or container body is inserted. Said joining device includes a cam mechanism for a linear motion of actuation means co-operating in an expansion and retraction deformation movement of the expansion bushing and simultaneous expansion of at least one portion of said casing or container body, with said cam mechanism and actuation means housed in the casing or container body and actuated by a tool.

Abstract: A corner fitting includes a strip-like base member for a clamping connection between two furniture panels which are arranged substantially perpendicularly to each other. A lip protrudes from the corner fitting in an end region of the base member along at least a portion of the width. In the opposing end region of the base member a pin protrudes, wherein the lip and the pin protrude at the same side of the base member substantially in the same direction.

Abstract: A fitting part for tool-free fastening in a bore in a panel includes a radially outwardly expandable expansion sleeve for insertion into the bore and a fitting housing, which is mounted in the expansion sleeve so as to be rotatable about an axis of rotation between a starting rotary position and a final rotary position, has a lever arm which is arranged outside the expansion sleeve and has a latching device, and has an expansion contour which is arranged inside the expansion sleeve and, upon rotation of the fitting housing in the expansion direction of rotation from the starting rotary position to the final rotary position, expands the expansion sleeve radially outwards.

Abstract: A rear wall/panel connector includes a stud, which has a receiving groove and two walls projecting vertically from the stud on both sides of the receiving groove. The two walls each have an opening configured for screwing in a screw. One of the two walls forms an arm of a rocker which is mounted on the stud wherein it is pivotable between a starting position and an end position about an axis which is parallel or almost parallel to the longitudinal direction of the receiving groove. The inside of the second wall is positioned obliquely outwards with respect to the longitudinal center plane of the receiving groove in the starting position and extends parallel to the longitudinal center plane in the end position.
