Abstract:
In a tilt handle, including a steering shaft, supported by a sleeve the lower end of which is pivotably provided so as to adjust an inclination angle of the tilt handle with relation to a car body, a device for adjusting the inclination angle of the tilt handle includes a stationary bracket, a movable bracket and spring means therebetween, the stationary bracket being positioned at a proper portion of the car body. The movable bracket is located at a suitable portion of the sleeve and is movable within the stationary bracket. The spring means is provided for energizing the sleeve to move upwardly.
Abstract:
A joint prosthesis comprises two relatively inextensible primary components that are spaced apart from one another. Disposed between and spaced from both of the components is a pivot member. The pivot member is resiliently secured to each of the primary components so as to permit relative rotation between the primary components and the pivot member. As a result, the two primary components of the prosthesis can rotate toward and away from each other about an axis that is disposed at least adjacent to and at least approximately parallel to a central longitudinal axis of the pivot member. The pivot member and the primary components of the prosthesis are preferably secured together by one or more bodies of elastomer.
Abstract:
For use in a trailing arm assembly having a support frame and a spring-loaded trailing arm pivotally mounted on the support frame, an adjustable stop element is provided for limiting the downward deflection of the trailing arm. The stop element is a rotatable eccentrically mounted element having a polygonal cross section, the surfaces around the polygon adjustably engaging the underside of the trailing arm, thereby adjustably limiting the downward deflection of the trailing arm. The deflection limiting element may conveniently be in the form of a rectangular parallelepiped eccentrically mounted between two guide plates which provide lateral support for the trailing arm.
Abstract:
The present disclosure discloses a variable torsion spring damping rotating shaft. The shaft includes a movable unit, a fixed unit, a first connection mechanism, a second connection mechanism, and a torsion spring; the fixed unit is detachable in inserting connection with the movable unit; the first connection mechanism is arranged inside the fixed unit, and the first connection mechanism is connected to an end of the fixed unit; the torsion spring is sleeved on the first connection mechanism, an end of the torsion spring is in inserting connection with the fixed unit, and another end of the torsion is in inserting connection with the movable unit; the second connection mechanism is arranged in the movable unit and is in cooperation with the first connection mechanism; and the second connection mechanism is configured to rotate on the first connection mechanism, to drive the movable unit to move towards the fixed unit.
