  • Patent number: 11839990
    Abstract: A knife has a knife handle and a blade, the blade being extendable and retractable in relation to the knife handle. A reinforcing part is provided which can support an extended portion of the blade, and is movable in respect of the knife handle and is detachably connected to the blade. Alternatively, the knife has a blade-moving carriage and/or a reinforcing part-moving carriage and a latching holder for latch-adjusting different extended positions of the blade is provided. In another embodiment, the blade-moving carriage has a holding magnet for holding cooperation with the blade. In yet another embodiment, a closing cap is arranged on the knife handle at the rear end of the blade, the closing cap closing the movement path for the blade-moving carriage and/or the reinforcement part-moving carriage.

  • Patent number: 8469600
    Abstract: A roller bearing cage for guiding rolling bodies in a rolling body bearing, which has multiple rolling bodies, two cage side elements, between which the rolling bodies are arranged, and which have multiple web appendages to guide the rolling bodies, and multiple connection elements that connect the two cage side elements. The azimuthal position of the connection elements defines a connection area. Exactly one connection element and at least one web appendage are arranged in a connection. The connection element and web appendage are arranged in sections inside a radial interior of the respective cage side elements, the border of which is defined by the positions of the rotation axes of the rolling bodies.

  • Patent number: 8277127
    Abstract: A bearing cage for large radial or axial roller bearings, which has two axially opposed, circular ring-shaped side washers held at a distance to each other by connecting elements, and roll-shaped rolling elements disposed between the side washers which have bolt-like elements on the faces thereof. A side washer on at least one side of the rolling element has radial recesses into which the bolt-like elements protrude. At least one securing element suitable for holding the bolt-like elements in the area of the radial recesses in the assembled state is provided. Shaped elements that can each be introduced at least partially into the radial recesses of the side washer are provided as the securing element. This construction achieves easy assembly and disassembly of the housing, allowing high flexibility in repairing a roller bearing so equipped.
