  • Patent number: 8205906
    Abstract: The invention relates to a rehabilitation children's sport stroller, comprising a frame (28), a seat (10), and a pivot device (16), which at least in some regions connects the seat (10) to the frame (28) pivotally about a seat pivot axis (S) and comprises a first joint (20) and a second joint (22), which are provided on the seat (10) on mutually opposing sides, wherein the first joint (20) and the second joint (22) can be locked, the first joint (20) comprising a first-joint operating element (40) for releasing the first joint (20). According to the invention, the second joint (22) is connected to the first-joint operating element (40) by means of a push-stable transfer device such that during an actuation of the first-joint operating element (40) the first joint (20) and the second joint (22) are released.

  • Publication number: 20100216334
    Abstract: Electrical service device having a cutout, which is arranged on an attachment face and at one end of which a movable lug is arranged, which lug can be latched in behind a longitudinal edge of a top-hat rail, wherein the movable lug is integrally formed on a latching arm, which protrudes on the attachment face at right angles thereto, and wherein a groove, which is open toward the movable lug, is arranged at the other end of the cutout, in such a way that, in the fitted state, one longitudinal edge of the top-hat rail is inserted behind the movable lug, and the other longitudinal edge is inserted into the groove. Furthermore, a spring element is provided which, once the service device has been fitted, presses in a sprung manner against the top-hat rail.

  • Patent number: 7579933
    Abstract: The disclosure relates to an electrical installation switching device, having a switching mechanism with a latching point which can be unlatched manually by means of a switching toggle or by means of an electromagnetic or thermal release, having a tripping lever which can be operated by the electromagnetic and thermal release and acts on the latching point, having a latching lever which forms one element of the latching point, and having a movable contact lever, which can pivot, is acted on by the electrical release in the event of a short-circuit and is moved permanently to the disconnected position by the switching mechanism in the event of a short-circuit or overcurrent. The latching lever (which is mounted in the enclosure such that it can rotate) together with the tripping lever forms the latching point. The tripping lever is mounted such that it can rotate on the same rotation axis as the switching toggle.

  • Patent number: 7528690
    Abstract: The invention relates to an electrical switching device, having a thermal release, an electromagnetic release, and a switching mechanism with a latching point. A contact base for moving a contact member is located between the thermal release and the electromagnetic release. The thermal release is coupled to a release lever by means of a connecting rod passing over the contact base so that both the thermal release and the electromagnetic release open the latching point in the event of an overcurrent and/or short-circuit current.

  • Patent number: 7504914
    Abstract: An electrical switchgear includes a thermal trip, an electromagnetic trip, and a switching mechanism with a latching point and at least one contact point that is continuously opened or closed. An operating handle is connected to one end of a lug by means of a coupling element and the other end of the lug is coupled to a contact base that carries a moving contact member. The thermal trip is coupled to a trip lever by a connecting rod that passes over the contact base so that both the thermal trip and the electromagnetic trip open a latching point in the event of an excess current and/or short circuit current.
