A power generation apparatus includes a rocker arm having a first end and a second end and is mounted pivotally between the first end and the second end, wherein reciprocal movement of the first end between raised and lowered positions urges reciprocal movement of the second end between lowered and raised positions. A pulley apparatus couples the second end of the rocker arm to a drive member, wherein reciprocal movement of the second end of the rocker arm between its lowered and raised positions urges reciprocal rotation of the drive member between first and second positions. A transmission interacts between the drive member and the output shaft, wherein reciprocal rotation of the drive member between its first and second positions urges rotation of the output shaft in one direction.

A syringe adapter having a syringe holder and an actuator are disclosed. The syringe holder may include a fixed portion that may receive a barrel of a syringe and an adjustable portion adjustably positioned relative to the fixed portion, where the adjustable portion may receive a plunger of the syringe. To facilitate aspirating fluid to and/or dispensing fluid from the syringe, the actuator may be selectively actuated with one or more digits or a palm of a user's hand to adjust a position of the adjustable portion. The selective actuation of the actuator may be performed with one or more digits of the user while two or more other digits are engaging a portion of the adapter adjacent a dispensing end of the syringe. The adapter may include a gear system translating movement of the actuator to movement of the adjustable portion of the syringe holder.

A ratcheting belt system with opposed rollers and quick release capability provides two opposed rollers which frictionally allow a tightening belt of a safety harness, cargo securement system, between themselves compressively, via a manually operated ratcheting handle such that the excess length of belt distal to the active portion used for securement is passed through the system substantially parallel to the active portion of belt, and need not be contained on a spool. A ratchet mechanism prevents back-out of the belt through the buckle, a manually operated lever provides for opening of the rollers away from each other and easy, quick exit of the driver, passenger, or cargo from securement.

A gear driven by wobble movement contains an ergonomic pendulum (D), a centric disk (C) and a flywheel (A) having a common axis (S) of rotation. In the axis (S) of rotation a shaft (H) is placed which is joined to the pendulum (D). The mutual concentric position of the centric disk (C) and the flywheel (A) is delimitated by planet disk (B) which contacts the periphery of the centric disk (C) and the internal periphery of the flywheel (A) and is joined rotatably to the supporting structure (T). The supporting structure (T) is fixed to the linked structure which fixes the supporting structure (T), together with the planet disk (B), against rotation with respect to the axis (S) of rotation. A first freewheel (V1) is situated between the shaft (H) and flywheel (A) and a second freewheel (V2) is situated between the shaft (H) and centric disc (C).

A conveyance to carry humans, such as a wheelchair, is described having levers on each side of the wheelchair that are manually moved forward and backward to propel the conveyance. The levers are connected to a tooth clutch mechanism that allow the user to shift into forward, reverse or neutral, brake, and change mechanical advantage (gear ratio), all this without removing the user's hands from the drive levers.

A rotary high lifter and controlled descender has a main housing enclosing a ratchet spool, controlled descender, and locking pawl. An adjustable crank turns the ratchet spool and takes up rope which raises an attached feeder, nestbox, etc. The locking pawl assures that as the rope is wound, the lifter/descender automatically locks in place so that an inadvertent crank release of the crank does not cause the feeder to fall. The rope exits the main housing via an inlet nipple which protects the housing from the elements, insects, etc. To lower the feeder, actuate a cam lock to release the locking pawl, and turn the crank in the opposite direction. Releasing the cam lock can actuate a controlled descender portion of the invention. These components apply a brake-pad-like action against the ratchet spool (can also use a tension knob) to control the speed of rotation and descent.

A tensioning device for a load carrier, such as a bike carrier or a roof box. The tensioning device includes a torque limiting mechanism which is adapted to limit the amount of transferable torque. The torque limiting mechanism includes a first torque transmission member and a second torque transmission member. The first torque transmission member is biased into working cooperation with the second torque transmission member such that upon a torque threshold value, the first and second torque transmission members are disengaged from working cooperation so that a torque limiting function is provided. An activation member is associated with the first torque transmission member, which enables a user to operate the first torque transmission member to transfer torque to the second torque transmission member.

An auxiliary bicycle transmission for a bicycle has a crossbar formed by a telescoping bar slidably mounted in an outer channel member. One end of a half chain or half V-belt is connected to the telescoping bar, the other end is connected by means of a spring to the upper end of a down tube, and the chain or V-belt that engages a freewheeling sprocket or pulley so that when the telescoping bar extends out of the outer channel member against the spring force, the freewheeling sprocket rotates and provides additional motive force to the standard transmission of the bicycle.

A rotator mechanism for rotating an elongate member that is coupled to a reciprocating member of a pumping system includes: a body having a through-hole for receiving a portion of the elongate member; a first freewheel clutch configured to cause the elongate member to rotate incrementally about the body axis in a predetermined direction when the reciprocating member reciprocates; and a second freewheel clutch spaced from the first clutch and configured to prevent the elongate member from rotating opposite the predetermined direction when the reciprocating member reciprocates. One or both of the clutches includes circumferentially-spaced clutch elements, that may include rollers or sprags or both.

The present invention relates to a system of converting kinetic energy into electrical energy, comprising: at least one element that produces kinetic energy; a shaft coupled to the at least one element and configured to reciprocate in a vertical direction, whereby a linear movement of at least one element exerts a pressure for enabling the reciprocation in vertical direction, wherein said shaft serves as a vertically elevated poll; and a flywheel fastened to the shaft and configured to receive and store one-way rotational energy from said shaft, wherein the form of the shaft facilitate the rotational movement of the flywheel, thereby enabling to use the rotational energy for the generation of electricity.
