Definitions

  • the present invention relates to a reduced-energy requiring rolling-mechanism. More specifically, the present invention relates to a reduced-energy requiring rolling-mechanism for moving a movable part of a mechanical assembly between a first predetermined position and a second predetermined position.
  • the rolling-mechanism of the present invention is especially useful for, though not limited to, adaptation for use in a roll-up blinds assembly for a window, an adjustable garden covering assembly, or a retractable irrigation line.
  • the rolling-mechanism of the present invention also allows for a convenient automatic use of said mechanical assembly without requiring connection to a wall outlet.
  • Such electrical means usually include an AC electrical motor connected to a stationary AC powers source.
  • Such means are not ideal for mobile assemblies, such as rotating mobile irrigation lines that are commonly used for home gardens and are also expensive to purchase and install. It would be desirable, therefore, to produce a mechanism that could be adapted for use in mechanical assemblies with movable parts, that would make the operation of the assembly easier and more convenient but at the same time, did not require as much energy, such that it could be operated through the use of batteries that would not have to be replaced so often.
  • the aim of the present invention is to provide a reduced-energy requiring rolling-mechanism adapted for usage with a mechanical assembly that has a movable part, movable between two predetermined extreme positions (and intermediate points therein).
  • the rolling-mechanism of the present invention overcomes the aforementioned problems by using a spiral spring in combination with a DC motor that can be powered through conventional batteries.
  • the use of a battery-operated DC motor eliminates the need for electrical wiring for connection to an electrical power source. It also enables the mechanism to be useful for mobile mechanical assemblies. Independently, such a low-energy motor would not be able to provide enough mechanical energy to move the movable part of the assembly (or, would require gearing means causing the operation to be extremely slow).
  • the movable part can be moved between a first or second predetermined position by introducing a small, but sufficient amount of mechanical energy from the DC motor to move the movable part at a satisfactory speed.

  • the reduced-energy requiring rolling-mechanism according to this embodiment may be designed for easy installation by a consumer into an already-existing, manually-operated roll up blinds assembly. Since the reduced-energy requiring rolling-mechanism is battery-operated, no long cords or other external electrical connections are needed.
  • the reduced-energy requiring rolling-mechanism may be affixed to an inside wall and attached to an already-existing strap that is connected to the roll-up blinds. Thus, when the strap moves upwards or downwards, the roll-up blinds are lowered to cover the window or rolled up into a housing located above the exterior of the window.
