Abstract
The invention relates to a device for positioning or extracting light bulbs from hard-to-reach places. The device has an extendable handle, and support attached to the handle and the main housing mounted on the support for a limited rotational movement about longitudinal axis of the support. A pair of independently activated electrical motors positioned within the housing operate the device. The first motor transmits a longitudinal movement to a piston having a suction cup for gripping a light bulb, and a second motor transmits rotational movement to the gripped bulb.
Claims14
An apparatus for inserting and extracting light bulbs comprising:
- a handle means;
- a support means attached to said handle means substantially perpendicularly thereto;
- a housing means attached to said support means opposite said handle means and adapted for adjustable rotation about said support means;
- a piston housing means secured to said housing means and adapted for a rotational movement independently from said housing means;
- a gripping means attached to said piston housing means for gripping a light bulb;
- said piston housing means housing a piston means adapted for an axial movement within said housing means for creating a vacuum between said gripping means and a light bulb to be gripped.
An apparatus for inserting and extracting light bulbs, comprising:
- a handle means, said handle means housing means for transmitting an operational power;
- a support means connected to said handle means;
- a housing means securedly attached to said support means opposite said handle means and adapted for adjustable rotational movement about the support means, rotation of the housing means allowing manipulation of a light bulb at an angled position;
- a piston housing means secured to said housing means and adapted for a rotational movement independently from said housing means;
- gripping means attached to said piston housing means for gripping a light bulb, said gripping means comprising a piston means adapted for axial movement within said piston housing means and a suction cup fixedly attached to one end of said piston housing means, axial movement of said piston means away from said suction cup creating a partial vacuum to allow gripping of the light bulb by the suction cup;
- an electrical motor means mounted within said housing means, said motor means comprising a first motor for transmitting rotational movement to said piston housing means and a second motor for transmitting a longitudinal axial movement to said piston means within said piston housing means, said first and second motor being operationally connected to the electrical power source.
