Abstract: A cam driver includes a support, a cam, a motor, and a retracting torque applicator. The support supports an object. The cam moves the support. The motor rotates the cam and maintains a position of the cam. The retracting torque applicator applies torque to the cam in a direction to move the object away from a counter object that faces the object.

Abstract: An oscillation drive with a drive and with an eccentric coupling drive for converting a rotary motion of the drive into an oscillating rotary motion of a tool spindle about its longitudinal axis is disclosed, wherein the eccentric coupling drive has an eccentric with a first eccentricity that is driven by the drive and that works together with a coupling element that is coupled to the tool spindle in order to convert the motion of the eccentric into an oscillating rotary motion of the tool spindle, wherein the eccentric is coupled to an additional eccentric with a second eccentricity so that the eccentricities are superimposed, wherein the relative position between the eccentric and the additional eccentric is adjustable to at least two different positions in order to change the amplitude of the oscillating motions of the tool spindle.

Abstract: A rotation transmission mechanism may include a drive wheel structured to rotate to one side, a driven wheel turned by the drive wheel to one side, and an urging member urging the driven wheel to turn to the other side. The drive wheel may include a drive teeth forming part where drive teeth structured to turn the driven wheel to the one side are provided at positions different from each other in an axial line direction, and a cam face forming part on which the driven wheel is slid. The driven wheel is provided with a driven teeth forming part where driven teeth provided at positions different from each other in an axial line direction are disposed over an angular range so that, when the drive wheel is turned to the one side, the drive teeth are sequentially abutted with the driven teeth.

Abstract: Disclosed are a support device and a folding furniture having the support device. The support device includes a base, a support mechanism, a fixed seat, and a force providing mechanism installed to the base. The support mechanism includes a support element and a rotating element rotatably installed to the base. The support assembly has an end hinged to the fixed seat and the other end having a disassembling structure for detachably connecting the rotating element. The rotating element abuts the force providing mechanism, and the force providing mechanism is provided for supporting the rotating element. The support device has an ingenious structural design, so that the support element and the rotating element can be installed or removed conveniently, and the operation is simple and labor-saving, and the lifting operation of the support element has the features of stable operation, low noise, and high practicality.

Abstract: An engine includes an engine shaft and a piston configured to reciprocate within a cylinder chamber having an axis, each piston having an first piston part and piston stem to move in unison with or separately from a second piston part to define piston strokes for different thermal functions of the engine. The engine further includes a linkage assembly having a first end coupled to the engine and a second end coupled to the piston stem defining a copy point, an actuator that engages the linkage assembly, and a guide cam that engages a guide cam follower on the linkage assembly. The actuator and the guide cam are operable to control motion of the linkage assembly to thereby define substantially linear movement of the copy point along the cylinder chamber axis.

Abstract: A pair of spaced-apart cam disks disposed along a common power shaft, with a pair of cam followers disposed within channels formed in opposing inner surfaces of the cam disks, forms a balanced arrangement for creating linear reciprocating motion from the rotation of the pair of cam disks. A linear motion shaft is coupled to the cam followers. As the cam disks synchronously rotate and the cam followers trace the path formed by the paired channels, this rotational motion is converted into linear, reciprocal motion that provides the translational movement of the linear motion shaft.
