A drive mechanism for a medication delivery device containing a resilient member and having a rotation member configured to be rotated in a first direction during setting of a dose of a medication and to be rotated in a second direction during delivery of the dose, where the rotation member is coupled to a drive member that is coupled to a piston rod such that on dose delivery the piston rod is displaced in a distal direction to dispense a medicament and where the resilient member prevents movement of the drive member and the piston rod during dose setting.

A disposable bidirectional ratchet, which has a tubular hollow handle with an interior surface having teeth thereon; a toggle mounted movably within the handle; a knob connected to an end of the toggle moves the toggle inside the handle; a plurality of pins on another end of the toggle; a plurality of actuators each comprising: fingers, levers, toes and a head, and having a post guide formed therein; a plurality of posts affixed to a clutch; and, wherein the actuators are movable affixed to the clutch via the posts, and the pin position selects the direction of engagement via adjustment of the actuator position via applying force to the levers, which moves the lateral edges of the actuator towards or away from the teeth.

A linear powered input device that utilizes linear input from a user and converts the linear input rotational energy to perform work. The linear input is generated by lever arms having a slotted attachment at a pivot point that allows a free end of the lever arms to move linearly rather than in an arcuate path. The lever arms are connected to a power transmission mechanism that wraps around one or more drive wheels having one-way bearings mounted on one or more output shafts. The output shafts can be connected to any type of auxiliary device to perform the desired work. Output wheels may be mounted on the output shafts and operatively connected by a transmission link that allows linear motion of any lever arm in any allowable direction to cause the output shaft to rotate in the same rotational direction so as to receive continuous input.

A hand operated tool for binding a load. The tool including a hollow tube with interior left hand and right hand threads at opposing ends. Opposing rods with exterior threads on one end and a releasable connection device on the other end that is screwed into each end of the tube. A gear rigidly mounted and encircling the tube allowing a pivotly attached ratcheting U-pawl to engage the gear teeth, the U-pawl attached to and carried by a handle assembly mounted on each side of the gear, the handle protruding perpendicular from the tube. The handle turning the tube in a first rotational direction drawing the rods closer together tightening the bind, the handle turning the tube in a second rotational direction moving the rods farther apart loosening the bind, the rods remaining stationary in rotation during rotation of the tube. A blocking device may be installed to prevent the U-pawl from pivoting into a position to turn the tube in the second rotational direction, that would loosen the bind on the load, the blocking device allowing normal ratcheting and turning of the tube in the first rotational direction tightening the bind on the load. A recessed-pawl partially pivoting independently of the U-pawl and engaging with the gear to prevent the tube from turning in the second-rotational-direction that would loosen the bind on the load when the U-pawl is in a neutral position whereby the U-pawl is not engaged with the gear. In addition, a tension-detecting-device suitable to detect or measure the tension on the ratchet load binder rods and also monitor and communicate the tension to the operator is also provided.

A drive train for a treadle scooter using a locking roller clutch on each side of a drive wheel substantially equalizes drive line pull at actuation pulleys operatively associated with the locking roller clutches as a user pivots a rocker board having its ends attached to ends of the drive line.

A spring component for a ratcheting mechanism, such as a ratchet wrench. The spring component is shaped to be retained in a recess without any special machining. For example, the spring component can be retained at three abutment points. A leaf of the spring component can abut a pawl, and a base portion opposite the leaf can abut the drive gear. Support arms can abut the sidewall of the recess to retain the spring component within the recess without the need for special machining or tooling.

An electricity generation system using tire deformation comprises driving mechanisms converting deformation of a tire into a driving force; and an electricity generation mechanism generating electricity using the driving force converted by the driving mechanisms, wherein the driving mechanisms convert only deformation due to expansion after compression of the tire into the driving force.

An energy harnessing device for harnessing wave energy that results in pitch, sway, yaw, surge, roll, and heave movement, wherein the device effectively converts multiaxial translational and rotational motion to unidirectional rotational motion for power transmission.

A quickly released and fastened adjustment mechanism including a gasket, a first ratchet, a second ratchet, a T-shaped sleeve and a fastener is installed between a sliding member and a fixing member. The first and second ratchets are arranged with annular teeth respectively while the two annular teeth are engaged. The T-shaped sleeve is mounted in the first and second ratchets and against the gasket. The fastener is passed through the T-shaped sleeve, the gasket and the sliding member to be secured on the fixing member. Thus the two corresponding annular teeth are engaged firmly. The height difference between low-level and high-level engagement of the two annular teeth is H.sub.f. The sleeved height of the T-shaped sleeve is D.sub.1. The total height of the first and second ratchets in the low-level engagement is D.sub.2. D.sub.1>D.sub.2. D.sub.1−D.sub.2=G>0 and H.sub.f>G>0.
