Abstract
An extendible ceiling hook comprises an apparatus for suspending a hanging plant at various distances from a ceiling for the purposes of ease of maintenance, appearance and the general well being of the plant. An extension line, wound on an extension spool inside the extendible ceiling hook may be reeled in or out or made to rest at a desired distance from the ceiling by raising or lowering the suspended plant pot in a controlled fashion. The suspended plant can also be easily rotated to any desired angle to fully exploit any available sunlight and further enhance its appearance.
Claims5
An extendible ceiling hook, comprising an extension spool rotatable upon an axle mounted inside an assembly housing sealed with an assembly housing seal, the rotation of said extension spool being governed by a spring;
- an extension line secured to said extension spool and wound around said extension spool, exiting from said assembly housing at an opening and with an extension line grip secured thereto at a point outside said assembly housing;
- a notch and stop bar arrangement inside said assembly housing which permits said extension spool to rotate with speed but prevents said extension spool from rotation in a direction which would allow said extension line to unwind from said extension spool when the rotational speed of said extension spool is slow;
- a securing shaft protruding from said assembly housing.
An extension device comprising:
- an extension spool rotatably mounted inside a housing for receiving an extension line secured to the extension spool and wound around the extension spool;
- a spring connected to the housing and to the extension spool for biasing the rotation of the extension spool towards a direction that winds up the extension line when the extension line is secured to the spool;
- and
- notch and stop bar means connected to the housing and to the extension spool, which means permits the extension spool to rotate in either direction through 360.degree. when the rotational speed of the extension spool is sufficiently fast, but prevents rotation through 360.degree. when the rotational speed of the extension spool is sufficiently slow.
