Abstract: An apparatus for adjusting the longitudinal position of a safety binding of a ski including a base plate attached to the binding and adapted to longitudinally slide in a guide on the ski. The base plate has a plurality of teeth adapted to engage a plurality of notches in the guide. Also provided is an apparatus for locking the teeth in the guide including a locking lever, a locking cam, and an elastic bearing. The locking lever is pivotally attached to the base plate by a first journal. The cam includes a second journal pivotally mounted on the base plate to rotate between locked and unlocked positions. Either the first or second journal is housed in the elastic bearing. Rotation of the cam from the unlocked to the locked position rotates the locking lever to displace the teeth into the notches and longitudinally displaces the journal housed in the elastic bearing, thereby compressing the bearing and biasing the teeth against displacement out of the notches.
Abstract: A wheel suspension for steerable wheels of motor vehicles, especially for rear wheels which includes a wheel carrier supporting the wheel. Of the wheel guide members (upper triangular guide member, lower individual cross guide members) one guide member is displaceable approximately in the transverse direction of the vehicle by way of an adjusting motor and additionally supports the support spring. With its inner end, this guide member is pivotally connected at an intermediate lever. This intermediate lever is pivotally supported at the vehicle body about a pivot axis extending approximately in the vehicle longitudinal direction and is connected at its lower end with the adjusting motor by way of lateral tie rods. The high bearing forces at the inner end of the guide member are absorbed in this manner principally by the intermediate levers and are kept away from the adjusting motor and the adjusting members thereof (tie rod, actuating member).

Abstract: A ski binding adapted to be displaced between a boot retaining and boot releasing position. The binding includes a jaw and two lateral arms pivotally connected at one end to the ski around a first transverse axis and pivotally connected at their other end to the jaw around a second transverse axis passing through a journal. Also provided is an elastic element for biasing the jaw against pivoting around the second transverse axis, and a retractable support. The support supports the jaw, the arms and the journal when the support is in its active position. The support is also retractable to an inactive position in which the jaw, the arms, and the journal are unsupported by the support. When the support is retracted into this inactive position the jaw, the arms, and the journal can be displaced around the first transverse axis to release the boot from the binding without substantial pivoting around the first transverse axis, and therefore without pivoting against the bias of the elastic element.
Abstract: A quick-release wheel retainer consisting of a hooked-shaped member having a generally planar shaped tab attached thereto and extending outwardly therefrom approximately perpendicular to the hook-shaped member. The member is pivotally connected to a vertical drop-out of a bicycle front fork and the pivot connection is positioned directly above the drop-out slot such that, once in a locked position about a bicycle axle, the weight of the axle against the member causes the retainer to remain in that locked position.
Abstract: The invention relates to an axle suspension means for motor vehicles, wherein the guide means of a rigid axle is constructed so that the latter changes its position in the sense of a positive oblique springing during inward spring stroke movements, and executes no inherent steering movements during one-sided and alternate-side inward and outward spring strokes. For this purpose the rigid axle is guided on each side by a pair of guiding control arms which determine, for its wheel axis, a pivot axis about which the wheel axis is movable by means of a guide arm retained on the vehicle body in the sense of the positive oblique springing during inward spring stroke movements.
Abstract: A motorcycle having a cantilever-type rear swing arm pivotally mounted to the vehicle frame. A cushion member associated with the rear swing arm extends between the upper frame and linkage below the swing arm through an offset bore in the swing arm. A rear wheel is arranged on an axle supported at one end of the rear swing arm with a brake disc therebetween. The brake disc is aligned with the centerline of the vehicle as is the wheel rim. The hub of the wheel is arranged with a concavity to accommodate the brake disc. The swing arm is arranged such that it gradually increases in thickness as it extends rearwardly from the front pivot. The thickness is maximized near the center of the swing arm at locations which approach the mutual tangent lines of the pitch circles of drive and driven sprockets of a chain drive mechanism. Sliders are positioned to accommodate the chain when necessary.
Abstract: A body cover for a motor scooter vehicle with a rear cover for covering the engine unit. The rear cover has a projection in its upper portion over the rear wheel, the projection having an outlet. Accordingly, the heat generated from the engine unit may be well discharged through the outlet of the projection to the atmosphere.

Abstract: A coupler for a pickup drawbar has a removable stud mounted to the end of the drawbar for engaging an implement hitch. A main bracket is mounted to the drawbar between the stud and the work vehicle. A top strap is pivotally mounted in the main bracket and is pivotal between a position engaging the top of the stud and a position removed therefrom to allow the implement hitch access to and from the stud. The top strap is lockable in its closed position engaging the stud and preferably also in its fully open position laying back against the drawbar. The coupler is readily modifiable for use with various implement hitches simply by replacing the stud and top strap.
Abstract: The hitching aid disclosed is for use with agricultural tractors. It is used to allow the tractor to be backed onto a trailer, whereupon the trailer becomes automatically hitched to the tractor. The aid includes a converging channel which receives the head of the trailer's draw-pin. The channel draws the pin-head into a throat, thus aligning the pin before the pin enters the pin-receiving jaws. Thus, any abusive loads due to mismatch, etc., are taken by the bulbous head of the pin and the channel, rather than by the shank of the pin and the jaws.
Abstract: Apparatus to reduce the force required to move a load along a flat or inclined surface utilizing an assembly of two traction wheels on a common axis whereby one wheel is free to rotate and the other is prevented from rotation and vice versa by the use of a uni-directional control arm system and means for applying a horizontal oscillating force in alternating left and right hand directions in the form of a relatively long handle attached to the axle housing midway between said traction wheels. The wheel assembly is particularly useful for trailers for carrying animals, small boats, recreational vehicles, two-wheeled hand trucks and similar applications.

Abstract: For the control of the drive slip of a motor vehicle a first rotation rate sensor produces a first rotation rate signal corresponding to the rotation rate of the driven wheel or the output rotation rate of the change-speed gear. A second rotation rate sensor generates a second rotation rate signal corresponding to the rotation rate of a non-driven wheel. The friction clutch of the motor vehicle is engageable and disengageable through a controllable servo drive, and a control system controls the clutch in the release direction when the first rotation rate signal represents a rotation rate higher by at least a pre-determined difference value than the second rotation rate signal. The control system controls the clutch in the engagement direction when the rotation rates represented by the first and the second rotation rate signals differ by less than the pre-determined difference value.
