  • Patent number: 7950123
    Abstract: Apparatus and methods for transporter shaft coupling and decoupling to assure alignment of a user interface with a control shaft through matching asymmetric cylindrical surfaces and alignment of an upper shaft segment and a lower shaft segment with ribs meshing with grooves on rings attached to the upper shaft. A tone confirms proper connection. Alignment apparatus is protected from damage associated with torques applied to the control shaft by tab features designed to first give way before other damage is incurred and from moisture by apparatus that seals the connection between upper and lower shaft segments. The user is protected from sudden loss of control by requiring the user interface to execute a sequence of linear and rotational manipulations during assembly of the shaft.

  • Patent number: 6634674
    Abstract: A telescopic dust collecting pipe includes an outer pipe, an inner pipe inserted in the outer pipe, and a locking mechanism used for locking the relative position of the outer and inner pipe. The inner pipe and the controlling rod form an outer layer oriented groove and an inner layer oriented groove. Relative movement of the controlling rod and inner pipe brings the outer layer oriented groove to coincide or stagger with the inner layer oriented groove. A locking element moved along the radial direction is arranged between the outer pipe and inner pipe. The locking element is pressed against one side of the inner pipe by an elastic element. The relative movement between the controlling rod and inner pipe can cause the double layer oriented grooves to be coincided or staggered, so as to press or to push the locking element into or out of the oriented groove, so that the outer pipe and inner pipe are locked or released.

  • Publication number: 20030042738
    Abstract: The invention concerns a connector to connect two parts of a brake conduit where the connector permits axial movement without variation of the volume of the conduit. The connector is used in the suspension fork of a motorcycle. The brake circuit is the hydraulic connection between a handle and the brake cylinder of the front wheel. The connector makes it possible to integrate the brake circuit into a leg of the fork. The variation in length is necessary to compensate the suspension movement of the fork. The invention aims at a brake circuit connector which can be mounted in the centre of the leg. Because of the permitting of axial movement without variation of the volume of the circuit the brake conduit can completely be built in. Because of the absence of hoses the brake circuit is very direct in the transmitting of the brake force. Also protruding parts are completely avoided.
