Abstract:
A coupling structure of a variable length shaft, comprises a pipe member having an end formed with a plurality of slits elongated in the axial direction to be capable of expanding and diminishing in diameter, an intermediate shaft spline-fitted in the end of the pipe member, and a ring member fitted on an outer periphery of the end of the pipe member, the intermediate shaft being fastened by the end of the pipe member. A holder is releasably attached to an end of the ring member to expand a diameter thereof and thereby reduce a slide frictional resistance of the pipe member against the intermediate shaft. When the holder is released, the ring member diminishes in diameter, and a fastening force of the pipe member on the intermediate shaft is increased.

Abstract:
A device for attaching a steering wheel on a steering shaft by a connecting sleeve, which is attached to the hub of the steering wheel. At its end, the steering shaft has a section with exterior splines, which are complementary to interior splines in the connecting sleeve. The connecting sleeve has an axial slot and is clamped by a clamping screw against the section of the steering shaft which has the splines. The steering wheel constitutes a sub-assembly with an integrated air bag module and may be supplied for the final assembly of the vehicle.
Abstract:
An extension handle is provided for extending the reach of a tool such as a paint roller or the like. The handle includes a first end presenting an axial opening, and is provided with a locking mechanism for locking the tool on the extension handle. The locking mechanism includes a housing supported on the extension handle at the first end and including a stepped inner surface presenting a plurality of axially extending teeth. A pin is supported by the housing for shifting movement in a direction transverse to the length of the extension handle between a locked position extending into the opening and an unlocked position withdrawn from the opening, and a biasing member biases the pin toward the locked position. A release button releases the biasing member and shifts the pin to the unlocked position. The extension handle is adapted for use with a special tool having a handle presenting a free end that is sized for receipt in the axial opening of the extension handle and that includes a cavity within which the pin is received when the handle is positioned in the axial opening and the pin is in the locked position. However, through the use of adapters, the extension handle can also be used with conventional tools having handles presenting internally threaded open ends or quick-release mechanisms.
Abstract:
A probe and socket assembly (10) for serving as a mechanical interface. The assembly comprising a socket (11) having a housing (14) adapted for connection to a first supporting structure and a probe (12) which is readily connectable to a second structure and is designed to be easily grappled and manipulated by a robotic device for insertion and coupling with the socket. Cooperable automatic locking means (35, 49) are provided on the probe shaft (43) and socket housing (14) for automatically locking the probe in the socket when the probe is inserted a predetermined distance. A second cooperable locking means (92, 25) on the probe shaft (43) and housing (14) are adapted for actuation after the probe has been inserted the predetermined distance. Actuation means (80, 62) mounted on the probe are responsive to the grip of the probe handle by a gripping device, such as a robot for conditioning the probe for insertion and are also responsive to release of the grip of the probe handle (51) to actuate the second locking means to provide a "hard" lock of the probe in the socket.
Abstract:
A splined assembly 10 is disclosed and includes a generally annular outer spline member 12 into which a second generally annular inner spline member 14 is rotatably placed. Member 12 includes a plurality of splines 22, 24, each having a snap ring reception slot 30 formed therein. In a first embodiment, housing member 12 also includes a band 34 which substantially surrounds the housing member 12 and overlays slots 30. In a second embodiment, housing 12 includes a plurality of elliptically protruding portions 40, each of which is positioned between pairs of adjacent splines 22, 24. Both band 34 and portions 40 are effective to prevent structural deformation caused by the received snap ring.
Abstract:
A small gas turbine engine including a power turbine shaft and a gearbox input shaft co-axially aligned one with the other and mounted in three bearings. The power turbine shaft is provided with a male conical surface while the gearbox input shaft is hollow and includes a female conical surface adapted to mate with the male conical surface of the power turbine shaft. The power turbine shaft also includes an axial projection being threaded and inserted within the hollow portion of the gearbox input shaft. A nut having a shoulder is threaded onto the threaded projection of the power turbine shaft and engages a shoulder provided within the hollow gearbox input shaft such that torsion applied to the nut will force axial engagement of the conical surfaces. A complementary spline section may be provided, on the one hand, between the nut engaging shoulder and the female conical section on the gearbox input shaft. The complete coupling is within the diameter of the two co-axial shafts.
Abstract:
A device for adjusting the angular position of rotation of a steering wheel hub of a motor vehicle relative of a steering shaft utilizing a bushing which is located between these parts and connected to each of these by sets of teeth distributed uniformly over the inner and outer periphery of the bushing and wherein these teeth offer a large number of possibilities of angular adjustment as a result of the engagement of one set of teeth with the steering wheel hub for a coarse adjustment and as a result of the engagement of the other set of teeth with the steering shaft for an even larger possibility of minor angular adjustment.
Abstract:
A spline joint includes an externally splined shaft end and an internally splined hub end engaged therewith. The shaft end has an annular groove around the spline portion wherein a plurality of locking balls may ride. The hub has the same number of holes as there are locking balls, each of which hole is adapted to receive a locking ball. A sliding sheath surrounds the hub. This sliding sheath has an annular projection and an annular groove in axially spaced relation around its internal face. The annular projection presses against the locking balls when the spline joint is in operation. The annular groove embraces a polygonal spring, the spring having the same number of sides as the number of locking balls. The center of each side of the polygonal spring presses against a lock ball from a radially outward position and prevents the lock balls from going out of position when the spline joint is being detached. Thus, one-touch attach/detach operation is possible by moving the sliding sheath axially relative to the hub.
