Abstract
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.
Claims4
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.
