The elastic motor comprises annular-shaped elastic member, supported by means of a first bracket assembly consisting of a supporting bracket positioned between a first pressing bracket and a second pressing bracket for carrying out the straining of said first elastic member, the brackets being fixed on a base plate, on a circular path according to the projection of the circumference of the elastic member, wherein the distance between the second pressing bracket and the supporting bracket is bigger than the distance between the first pressing bracket and the supporting bracket. The first and the second pressing bracket are provided with some adjusting screws whose rotation determines the translation of a threaded bushing connected with balancers, determining the movement thereof and the straining of said first elastic member and the movement thereof from the second pressing bracket towards the first pressing bracket.

The present invention provides a spring return device comprising a rotatable drive coupling configured for releasably engaging a rotatable drive part on a first side of the device and configured for releasably engaging a rotatable drive part on an opposite second side of the device. A spring is engaged with the drive coupling, and a retainer retains the spring. The drive coupling is rotatable relative to the retainer, wherein rotation of the drive coupling relative to the retainer in a first direction causes mechanical energy to be stored in the spring. The spring return device further comprises a limiter element that is arranged to rotate with the drive coupling, and one or more stopping surfaces comprising a first stopping surface arranged to abut a first limiter surface on the limiter element when the drive coupling is in a first predetermined rotational position, to thereby limit rotation of the drive coupling relative to the retainer in a second direction, the second direction being opposite to the first direction. The spring return device of the invention may facilitate reversing the direction of operation of the spring return device.

The Mechanical battery stores kinetic energy in the form of Potential Energy then converts it to electrical energy and has five ways to recharged which are the manual method, Manual Automatic method and in association with wind energy as well as the home electricity and solar energy.

What is new in the invention?

It is that the battery stores the kinetic energy in the form of Potential Energy then converts it to electrical energy, as well as the small ones of the same doesn't need chargers and have a long useful life compared to others, it is eco-friendly and also make advantage of both wind and solar energy complete and stable and generates AC or DC generating 1, 2 or 3 phases as needed.

In at least one implementation, a torsion rod preload device, includes a body, a driver and a retainer. The body may have a base adapted to be connected to a vehicle and at least one stop. The driver is carried by the body for movement relative to the body, and is adapted to engage a torsion rod so that movement of the driver relative to the body increases a torsion force within the torsion rod. The retainer is carried by one or both of the body and the driver, and is movable by the driver as the driver moves relative to the body. The retainer is engageable with the stop to inhibit or prevent movement of the driver when the retainer is engaged with the stop to maintain a desired torsion force in the torsion rod.

An elastic energy storage and deployment system deploys a torsional spring that bias a cam connected to a cable. The cam is coupled to the torsion spring about a shared rotational axis such that the cam directs elastic energy to and from the torsion spring and the cable transforms rotational force into linear motion, with little rotational inertia, and the addition of angular acceleration.

A spring-assisted cordless roller shade without clutch system includes a tubular body defining an internal space. A shade is wound on the tubular body. The internal space has a first section and a second section. In each of the first and second sections are mounted a connector, a central shaft assembled with the connector, a fixing member connected with the central shaft and a subsidiary shaft disposed on the fixing member. An elastic member is disposed between the connector and the central shaft to provide a frictional force. A rotational member and a torsion spring are mounted on the subsidiary shaft of the first section and rotatable along with the tubular body. A constant force belt spring module is assembled with the subsidiary shaft of the second section. When the operational force applied to the shade disappears, the shade is immediately located.
