A first driven lever of a vehicle wiper device has a proximal end pivotally connected to a distal end of a first driving lever. A second driven lever has a proximal end pivotally connected to a distal end of the first driven lever and a distal end pivotally connected to a distal end of a second driving lever. A first wiper arm operates integrally with the second driven lever and has a distal end to which a first wiper blade is connected. A swing transmission mechanism transmits a driving force to the first driving lever. The swing transmission mechanism includes a swing crank arm integrally rotatable with a rotation shaft of a single drive source. An extension-contraction transmission mechanism transmits a driving force to the second driving lever. The extension-contraction transmission mechanism includes an extension-contraction crank arm integrally rotatable with the rotation shaft of the drive source.

The present invention concerns a key (1) for locking a link including a U-section and a crank of a linkage of a wiper mechanism in a transport position, characterized in that it comprises: a shaft (11) having at one end a radial holding excrescence (13) and at the other end an enlarged head (15) intended to cooperate with a hollow part of the U-section forming the link, and a first radial finger (17) configured to be housed in a slot for locking the link in the transport position.

A gravity oscillating system which comprises a looped and suitably substantially circular track around which a heavy mass such as a ball travels in use, the track being supported from above or below to oscillate up and down as the ball travels around the track, and there being a power transfer mechanism linked to the track to be moved by the track as the track oscillates, the power transfer mechanism being linked to an electrical generator/dynamo whereby the movement is used to generate electrical energy and wherein the system has an oscillating electromagnetic drive comprising a plurality of electromagnets in an array around the track and which are successively momentarily energized to urge each successive part of the track around the track in a direction, upwards or downwards, to cause the track to dip down ahead of the rolling mass, without the drive contacting the track.

The solar tracking arrangement enables a plurality of parallel arranged PTCs to be directed towards the travelling sun. The solar tracking arrangement comprises a drive means, a transmission means, and a plurality of conversion means. The transmission means are connected with the drive means and to each of the plurality of conversion means. The transmission means is configured to convey an operating movement caused by the drive means to the plurality of conversion means, and each of the conversion means is configured to convert the conveyed operating movement into a pivoting movement of a respective one of the plurality of PTCs about a focus line, such that each of the pivoting movements directs the respective PTC towards the travelling sun. One or more of the conversion means are adjustably connected with the transmission means in a direction along the transmission means.

A motor includes a motor unit, a speed reduction mechanism, a motion conversion mechanism, and a housing. The motion conversion mechanism converts rotary motion of the speed reduction. mechanism into reciprocating rotary motion and transmits the motion to an output shaft. The speed reduction mechanism includes a worm, a first gear, and a second gear. The worm is disposed on a rotation shaft of the motor unit. The first gear transmits rotation of the worm and rotates about a first shaft. The second gear receives rotation of the first gear and rotates about a second shaft. The motion conversion mechanism includes a rotary member and a rod. The rotary member includes a sector gear and rotates about an axis of the first shaft. The rod couples the second gear and the rotary member. The output shaft includes an output gear that engages the sector gear.
