  • Patent number: 11913676
    Abstract: A PTC heating element has a casing that joins as a unit at least one PTC element, conductor paths electrically connected to the PTC element, and insulating layers bearing, in a heat-conductive manner against the PTC element. The PTC heating element also has contact strips which project over itself and which are electrically conductively connected to the conductor paths for energizing the PTC element with different polarities. The casing forms a receptacle space that receives the PTC element, the conductor paths, and the insulating layers. In order to improve heat decoupling from the PTC element, the receptacle, in a cross-sectional view, is defined by two oppositely disposed inner surfaces covering the PTC element and concave cavities, adjoining the inner surfaces and forming the longitudinal edges of the casing, the diameter of which is greater than the distance between the inner surfaces. The electric heating device has at least one PTC heating element arranged in a circulation chamber.

  • Patent number: 11204053
    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. The other rocker arm projects outwards over the stud, at least in the end position.

  • Patent number: 11085476
    Abstract: A fitting for releasably connecting two furniture parts includes a first fitting part fastened on a first furniture part and a second fitting part fastened on a second furniture part. The second fitting part has at least one rigid latching cam which is engaged behind by a latching nose being provided on a deflectable latching tongue of the first fitting part. The latching tongue can be moved from its locking position engaged behind the latching cam, into a release position which can be fixed to the second fitting part. The latching tongue has at least one latching spring which can be deflected transversely to the deflecting plane of the latching tongue by a counter bearing of the second fitting part. The free spring end of the latching spring remains deflected by the counter bearing from the locking position until before the release position of the latching tongue is reached.

  • Patent number: 10711499
    Abstract: A soft closing damper fitting includes a soft closing damper fastenable to an internal door leaf of a multi-leaf sliding door and can be used for right-hand or left-hand closing. A Z-shaped profiled sheet has a central leg and with two outer legs angled in each case by 90° in opposing directions. For fastening the soft closing damper for right-hand closing the central leg comprises first fastening holes and a first marking for its fastening position on the internal door leaf. For fastening the soft closing damper for left-hand closing the central leg comprises second fastening holes and a second marking for its fastening position on the internal door leaf. The first fastening holes are spaced apart from the second fastening holes and the first marking is spaced apart from the second marking in each case by the same distance A in the longitudinal direction of the profile.

  • Patent number: 10584732
    Abstract: A connecting expansion bolt over-molded with an expansion sleeve includes a bolt head at one bolt end and a bolt cone tapering in the direction of the bolt head. At the other bolt end, the bolt cone and an adjoining bolt shaft portion are over-molded with a plastic expansion sleeve, the sleeve end of which that surrounds the bolt cone is divided into a plurality of spreadable sleeve segments by open-ended slits. Provision is made for the sleeve end that surrounds the bolt cone to be divided into at least three sleeve segments. For at least two of the slits on the bolt cone that separate the sleeve segments from one another do not extend parallel to the bolt axis.

  • Patent number: 8939673
    Abstract: A shelf carrier having an insertion pot with a T-shaped suspension opening on a side wall, the suspension opening being formed by a longitudinal slit extending parallel to the pot axis and by a transverse slit extending perpendicularly thereto. The longitudinal slit is open at an end facing away from the transverse slit. A slider is supported in the insertion pot so as to be displaceable transversely to the longitudinal slit. A longitudinal slit is formed on the slider, which extends parallel to the longitudinal slit of the insertion pot and is open at an end facing away from the insertion pot transverse slit, and forms a common insertion slit together with the insertion pot longitudinal slit in a center position of the slider. The slider is lockable with the insertion pot in the center position and/or in end positions transversely shifted to both sides of the center position.
