This stick is designed to be a walking stick, a rescue tool, and a conversation piece. Primarily, it consists of a main body with a handle at one end and a hook is provided at the other end for engaging with a ground surface and hooking onto an article. The design further includes a cup portion for preventing the hook from sinking into soft ground, and a rope is wound on the main body and is releasable at one end when needed for rescue work, etc.

There is provided an improved shaft seal especially adapted for use on a rotating shaft, and characterized by a seal ring, a channel-form circular seal member disposed between the channel-form retainer and the seal ring, and locking means coacting between the seal ring and the channel-form seal retainer. In a specific embodiment, the seal ring is provided with a key member or plurality thereof, and the seal retainer is provided with keyways which coact in assembly to prevent relative rotation of...

This invention provides a telescopic shaft in which a backlash or a sliding resistance in a rotational direction is maintained to a predetermined value even when there are fabrication errors in a male shaft and a female shaft, and a preload is not reduced even when a sleeve is worn by a friction force in sliding, and a steering apparatus having the telescopic shaft. An inclined sleeve portion 712 is pressed by an elastic deformation of an urge sleeve portion 713, so that there is not backlash be...

The invention relates to a balancing shaft, whose balancing weight is located between two cylindrical bearing surfaces and which is configured as one piece with said weight. The end cross-sections of the balancing weight are circular segments that are delimited by an arc and a secant. The aim of the invention is to configure the balancing shaft in such a way that the mass effect and rigidity are optimal. To achieve this, the contours of the balancing weight on the plane that is fixed by the seca...

A longitudinal shaft for use in particular in four-wheel drive or rear-wheel drive motor vehicles includes a gearbox-side articulation, a differential-side articulation, as well as a central articulation through which a gearbox-side section is integrally linked in rotation to a differential-side section of the longitudinal shaft. To reduce the centrifugal forces occurring at the longitudinal shaft 1 in operation, the gearbox-side articulation and the differential-side articulation have each an i...

A club shaft composed of a club shaft body and a single- or multi-layered coating film covering said club shaft body, wherein said coating film includes a coating layer having good scratch or scuff resistance and high resilience. The club shaft keeps its good appearance owing to its self-healing ability even though it is damaged during carry in a caddie bag.

An endoscope shaft comprising a working conduit and a number of supply and/or functional conduits. The supply and/or functional conduits have an excessive length with respect to the endoscope shaft and are arranged in spirals, in serpentine and/or zigzag shape around or along the working conduit, whereby a flexibility and bendability of the endoscope shaft is achieved.

The present invention provides a rotor shaft, comprising: a rod member (26); and a plurality of separately formed component parts (such as a compressor wheel 10, a turbine wheel 11 and a rotor 14 of an electric generator) through which the rod member extends so that the plurality of component parts are joined together on an axis of the rod member, wherein mutually facing axial end surfaces of adjoining ones of the plurality of component parts are formed with annular projections (22, 23) having a...

A crash optimized propeller shaft includes a swaged tube to connect ends having disparate diameters. The variable diameter tube creates a stress concentration zone which allows the shaft to collapse or buckle in a controlled and predictable manner in response to predetermined loads.

A propeller shaft assembly includes a thin-walled tubular member, a connecting member fixed to each end of the tubular member, and a support member fixed within the tubular member. The support member includes a plurality of radial elements extending a first length (L1) within the tubular member and engaging an interior surface of the tubular member to increase the bending frequency of the propeller shaft assembly. In one example, the support member includes a central hub coaxially located within...
