Light bulb changing apparatus

Details

Primary Examiner: Cherry; Johnny D.

Attorney, Agent or Firm: Townsend and Townsend

The present invention discloses a light bulb changing apparatus which is normally mounted on the end of a rod (2) and takes the form of a body (1) having a substantially hemispherical cavity (3). A number of fingers (4) surround the cavity in order to assist in restraining a light bulb engaged with the body such that the hemispherical end of the light bulb is located within the cavity (3). The interior of the cavity permits a twisting force to be applied to the hemispherical end of the light bulb in order to permit it to be removed from, or inserted into, a light fitting.

DETAILED DESCRIPTION We claim: 1.
A light bulb changing apparatus, comprising: a body having a rod receptor which is shaped to receive one end of a rod therein to thereby support body by said rod; a cavity, said cavity having walls formed to be a substantially hemispherical segment of said body, opening away from said rod receptor and dimensioned to receive the hemispherical end portion of an incandescent light bulb; a plurality of restraining fingers circumferentially arranged around said walls of said cavity, mutually spaced apart, and protruding beyond said cavity away from said rod receptor to restrain an incandescent bulb within said cavity to prevent movement of the bulb away from said apparatus; wherein said body and said restraining fingers are fabricated in a single piece from a single moldable material which is substantially rigid; wherein said cavity has an interior surface a substantial portion of which is dimensioned to exactly correspond without deformation to the hemispherical end of the light bulb; and wherein each of said restraining fingers is substantially longer than it is wide whereby said restraining fingers are relatively resilient in the radial direction.
2.
Apparatus as claimed in claim 1, wherein said rod receptor further includes at least one radially directed, internally threaded aperture therethrough which threadably engages and cooperates with an externally threaded fastener to frictionally retain said rod within said rod receptor.
3.
Apparatus as claimed in claim 1, wherein said apparatus is molded from plastics material.
4.
Apparatus as claimed in claim 1, wherein said rod receptor comprises a sleeve dimension to form a frictional fit with said one end of said rod.

Description:
The present invention relates to light bulb changing apparatus and, in particular, to light bulb changing apparatus which enables substantially conventional incandescent light bulbs to be changed manually without being held in the hand of an operator.
BACKGROUND ART Incandescent light bulbs are well known and have a metallic base and a glass envelope with a substantially hemisperical end or tip
