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 drive mechanism for a medication delivery device is presented having a housing, a rotation member that rotates in a first direction with respect to the housing during setting of a dose of a medication and rotates in a second direction with respect to the housing during delivery of the dose, the second direction being opposite to the first direction. The device also has a piston rod that is displaced in a distal direction with respect to the housing for delivering the dose, a drive member which follows rotational movement of the rotation member in the second direction during delivery of the dose, and a stop member which prevents rotational movement of the drive member with respect to the housing in the first direction during setting of the dose.

This invention relates to an energy transfer arrangement of a wave energy recovery apparatus comprising at least a base, a reciprocating panel, supporting legs and a pivot shaft for the reciprocating panel, and a driving and power-take-off arrangement equipped with an actuating mechanism and one or more power-take-off units to convert kinetic energy of waves or tidal currents to another type of energy, each PTO unit comprising a power transmission mechanism. The actuating mechanism is arranged to transfer the reciprocating motion of the panel mechanically to a linear motion of the power transmission mechanism of each PTO unit.

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 operating mechanism is provided for a screen assembly having an elongate endless pull cord hanging from the screen assembly in a loop. The operating mechanism has a housing having an opening at an upper end thereof. At least a lower portion of the pull cord can pass into the housing to be enclosed therein. A guide means for guiding passage of the pull cord through the housing. The guide means has a locking means adapted to selectively restrain first or second sides of a loop defined by the pull cord. The guide means includes a cord-retaining member engaging a lower end of the looped pull cord. The cord-retaining member is moveable within the housing between vertically spaced first and second positions, the second position being above the first position, the cord-retaining member being biased towards the first position by biasing means. The housing may be displaced downwardly with respect to the pull cord by upward movement of the cord-retaining member between the positions against the force of the biasing means.

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.

A wave energy conversion arrangement comprising, at least two modules (M1, M2) each of which comprises, at least one first float (P1) and at least one second float (P2) coupled mechanically with each other by means enabling for reciprocal and independent displacing of these floats in relation to each other over a predetermined length segment along separate straight lines parallel to each other; at least one elementary energy conversion arrangement (7) using reciprocating movement of said at least one first float (P1) of a given module (M1, M2) relative to said at least one second float (P2) of this module (M1, M2), connecting means (16) for alternative detachable connecting with each other; wherein said elementary energy conversion arrangements (7) of the adjoining modules (M1, M2) are energetically coupled with each other constituting a main energy conversion arrangement (15).

The present invention relates to a self-power generating apparatus that can generate power by converting an external force that alternately acts in a forward and reverse direction into a unidirectional force, and can generate power by winding a wire around a pulley axially coupled to a drive shaft and applying, by a user, an external force to the wire with his/her hands to rotate the pulley in a forward and reverse direction, thereby enhancing power generation efficiency. To this end, the self-power generating apparatus comprises: a drive shaft alternately rotated by an external force in a forward and reverse direction; a forward power transmission part that transmits only the forward rotating force of the drive shaft to a power generating shaft; a reverse power transmission part that transmits only the reverse rotating force of the drive shaft to the power generating shaft; and a power generator that generates power using a unidirectional rotating force of the power generating shaft.

The gear driven by wobble movement contains an ergonomic pendulum (D), a centric disk (C) and a flywheel (A) which have a common axis (S) of rotation. In the axis (S) of rotation a shaft (H) is placed which is rigidly joined to the pendulum (D). The mutual concentric position of the centric disk (C) and the flywheel (A) is delimitated by one planet disk (B) at least which contacts the outer 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. Between the shaft (H) and the flywheel (A) a first freewheel (VI) is situated while between the shaft (H) and the centric disk (C) a second freewheel (V2) is situated. The senses of rotation of the freewheels (VI and V2) are different. The vehicle comprising this gear has a linked structure to which the supporting structure (T) is fastened, having the form of the frame (U). To it the wheel (K) or the pair of wheels (K) are fastened.
