Abstract
Disclosed are an electric spiraling piston and systems, devices, apparatuses, and methods utilizing same. An electric spiraling piston includes a drum around which the piston spirals as it is being retracted. A spinning axis of the drum is functionally connected to the drive shaft of a motor, such that motor torque is relayed to the axis. The axis, when spinning with the drum in a first direction, causes the piston to un-spiral and extend out of a housing —while rounding its cross section — to assume a straight, rigid position/orientation. The Axis, when spinning with the drum in a second direction, causes the piston to be retracted back into the housing — while flattening its cross section — to assume a spiral orientation within the housing.
Claims13
An electric spiraling piston comprising:
- a drum around which said piston is spiraled when in a retracted orientation, said drum positioned within a piston housing;
- and
- an electric motor having a drive shaft connected to a central axis of said drum such that motor torque is relayed to the axis causing said drum to spin, wherein, when said drum is span by said motor in a first direction said piston un-spirals and extracts out of said piston housing in a straight orientation and when span by said motor in a second direction said piston spirals around said drum and retracts into said piston housing;
- wherein said piston housing further contains one or more outer-drums positioned around, and in parallel orientation to, said drum, such that when said piston is spiraled around said drum, an external side of said piston contacts said one or more outer-drums;
- wherein said drum, and said outer-drums, each comprises a gear retained to its base;
- and,
- wherein each of said outer-drums gears is intermeshed with said drum gear, such that when said drum is span by said motor, rotational motion is transmitted from said drum gear to said outer drums gears causing said outer drums to spin in a direction opposite to the spinning direction of said drum.

A motorized curtain comprising:
- a curtain including:
- a rollable rectangular sheet;
- a first curtain pole connected to a first edge of said rectangular sheet;
- and
- a second curtain pole connected to a second, opposite, edge of said rectangular sheet;
- and
- an electric spiraling piston unit including:
- a drum around which said piston is spiraled when in a retracted orientation, said drum positioned within a piston housing;
- an electric motor having a drive shaft connected to a central axis of said drum such that motor torque is relayed to the axis causing said drum to spin, wherein, when said drum is span by said motor in a first direction said piston un-spirals and extracts out of said piston housing in a straight orientation and when span by said motor in a second direction said piston spirals around said drum and retracts into said piston housing;
- a first curtain connector for retaining said piston housing to said first curtain pole;
- and
- a second curtain connector for retaining a tip of said piston to said second curtain pole, such that upon extraction of said piston by said motor, said first curtain pole remains stationary and connected to said piston housing and said second curtain pole travels, along with and with support of said piston tip, away from said piston housing
- - thereby unrolling said rectangular sheet from a rolled position to an unrolled position to close said curtain.

- - thereby unrolling said rectangular sheet from a rolled position to an unrolled position to close said curtain;
- a potentiometer functionally associated with said drum for measuring specific electric resistance levels based on said drum’s rotational orientation;
- and communication circuitry for relaying data indicative of the measured electric resistance levels to a user communication device running a mobile device application;
- and
- said mobile device application for:
- calculating, based on a given measured electric resistance level, the length of a segment of said piston that is extracted out of said piston housing;
- and visually presenting, over a screen of the user communication device, the length of the segment of said piston that is extracted out of said piston housing, relative to a predefined length of a segment representing a full extraction of said piston.
