This invention is in the field of covers for light bulbs and more specifically to tools for installing and/or removing the covers.
Festive decorating of homes and businesses has included colored lights, most commonly Christmas lights. Soffit lights in the form of BR30 pot lights have become a common place for colored bulbs. To change the bulbs to festive colored bulbs, one would use a ladder, which may cause injury or inconvenience. Another method to change the bulb was a special device on the end of pole, which was prone to damaging the fixture by twisting the bulbs in and out in a rougher manner than that by hand.
In the last decade, LED type bulbs have become very popular and we are seeing less of incandescent bulbs. During this transition, it seems that the manufacturing of the colored BR30 bulbs has ceased, however, other shaped color bulbs are still available. Manufactures have replaced the colored bulbs with light & color-changing LED bulbs controlled by Wi-Fi at a much higher cost to the consumer and some have negative issues in colder weather.
Color light filters have been marketed using mechanical attaching accessories with drawbacks during the installation. Magnetic attaching of accessories had potential but only work on metal light fixtures.
LED light type bulbs generate very little heat compared to the traditional incandescent type of bulb thus allowing the introduction to use plastic tight against the bulb. Some manufacturers use plastic for the housing instead of glass.
The invention comprises the aspects described herein in any and/or all combinations.
According to an aspect there is provided a tool for installing a cover for a light bulb within a fixture. The tool may have a tube-shaped body with an installation end and a central axis; a platform located within the tube-shaped body approximately a height of the cover from the installation end; and/or a handle attachment located near an opposite end of the installation end; the handle attachment may receive an extension pole. The platform may be contoured to a shape of the cover. The tube-shaped body may have a thickness sized so that the installation end fits between the light bulb and the fixture. A diameter of the installation end may be approximately 110% of a largest diameter of a light emitting end of the light bulb. The central axis of the tube-shaped body may be aligned with an axis of the light bulb; and the installation end may be pushed upward toward the light bulb until a cuff of the cover bypasses the largest diameter of the light bulb. An interior storage may be within the tube-shaped body.
According to another aspect, the installing tool may further comprise a pair of pivots on opposite sides of the tube-shaped body with an axis transverse to the central axis of the tube-shaped body; the pair of the pivots may receive a pair of rods extending generally parallel to the tube-shaped body and may couple to the handle attachment. Each of the rods may have a bend and an angled portion with the angled portion approaching the central axis of the tube-shaped body; and the angled portions couple to the handle attachment. The handle attachment may be generally aligned with the central axis of the tube-shaped body.

While the invention is claimed in the concluding portions hereof, example embodiments are provided in the accompanying detailed description which may be best understood in conjunction with the accompanying diagrams where like parts in each of the several diagrams are labeled with like numbers, and where:
With reference to
The cover 104 may be contoured to receive a light emitting end or face 110 of the light bulb 102. The cover 104 may extend partially onto a neck 112 of the light bulb 102 in order to maintain the cover 104 in position. The cover 104 may comprise a cuff 106 to facilitate maintaining the cover 104 on the light bulb 102. In this aspect, the cuff 106 may comprise a plurality of creases or indentations 108 around the cuff 106. In another aspect shown particularly in
Turning to
The tube-shaped body 202 may have a larger diameter 252 at the installation end 204 than the removal end 206. The diameter of the tube-shaped body 202 at each of the two ends 204, 206 may generally correspond to a diameter 114 of the light bulb 102. In some aspects, the diameter 254 between the two ends 204, 206 of the tube-shaped body 202 may be less than both the diameter at the two ends 204, 206. In some aspects, the diameter 254 at a position of a pair of pivots 210 may be at a minimum diameter for the tube-shaped body 202.
In this aspect shown particularly in
The cover 104 may rest on a platform 260 within the installation end 204. In this aspect the platform 260 may be located approximately a height of the cover 104 below the edge of the installation end 204 (e.g. approximately 20-mm for a BR30 bulb 102). This platform 260 may be contoured to generally match the contour of the cover 104. The contour of the platform 260 may provide a centering of the cover 104 within the tube-shaped body 202 and/or may provide a distributed force on the cover 104 to assist in sliding the cover 104 onto the bulb 102. The platform 260 may work in conjunction with the walls of the installation end 204 to push the cover 104 onto the light bulb 102.
During installation, the cover 104 may be placed on the platform 260 within the installation end 204. A central axis 230 of the tube-shaped body 202 may be aligned with the axis of the light bulb 102. The alignment of the central axis 230 and the axis of the light bulb 102 may reduce or prevent the cover 104 from falling off during high winds. The installation end 204 may then be pushed upward onto the light bulb 202 until the cuff 106 of the cover 104 bypasses the diameter 114 of the light bulb 102. In some aspects, installation of the cover 104 may be facilitated by applying pressure around the outer edge of the installation end 204, such as by using a handle.
Turning to
Generally, the removal end 206 may be placed over the light bulb 102 and cover 104 and one or more frictional elements on an interior surface of the removal end 206, such as arms 234, wedges 236, or elastics 270, may snag the cuff 106 of the cover 104 in order to remove the cover 104. The cover 104 may then fall into a cover storage 702 within the tubular body 202. The cover storage 702 may be a volume formed from the wall of the tube-shaped body 202 and the platform 260. The storage 702 may be sized to hold several covers 104 before filling the storage 702. In this aspect, the storage 702 may hold approximately 12 covers. In other aspects, the storage 702 may hold fewer or more covers depending on a size and/or a slope of a mold release angle. An oval or circular-shaped cutout 208 may be present through one side of the tube-shaped body 202 from the exterior of the tube-shaped body 202 to the storage 702 within the tube-shaped body 202. In this aspect, the cutout 208 may be located between the pair of pivots 210 and the removal end 206. The cutout 208 may facilitate easier removal of the covers 104 from the storage 702.
As shown particularly with reference to
When the removal end 206 is pulled in a downward direction, the arms 234 may catch on the cuff 106 thereby pulling the cover 104 from the light bulb 102. In some aspects, each of the arms 234 may comprise one or more catches 802 (e.g. grab edge) in order to improve friction between the arms 234 and the cuff 106 when the tool 200 is pulled in a downward direction. As shown in
In another aspect shown particularly in
When the tool 200 is pushed in an upward direction, the wedge 236 may provide a slope 238 the provides reduced friction with the cuff 106. Once the slope 238 passes the cuff 106, the wedge 236 may expand and a perpendicular surface 239 may engage the cuff 106. The perpendicular surface 239 may provide a higher friction than the reduced friction of the slope 238. In this aspect, the wedge 236 may be approximately 10-mm long with the perpendicular surface 239 being approximately 7-mm long. The slope 238 may be approximately 7-mm long.
In another aspect shown particularly in
Returning to
Returning to
In use, the handle attachment 218 may hold the rods 212 apart from each other at a distance such that a force or tension towards the central axis 230 of the tube-shaped body 202 may be experienced by the rods 212. The force may cause the ends of the rods 212 to be held within the centrally located holes 224 of the pivots 210 and the rods 212 may be aligned by the grooves 222. When the operator wishes to switch between the installation end 204 and/or the removal end 206 (or vice versa) as demonstrated particularly in
Although particular shapes and/or number of the arms 234 and catches 802, 236 are described herein, these parameters may be varied depending on a size and/or a shape of the covers 104 and/or the light bulbs 102. In some aspects, a length and diameter of the tool 200 may also be varied accordingly with the size and shape of the cover 104 and/or the light bulb 102.
Although the platform 260 is demonstrated as a continuous surface in
Although the aspects described herein have the cuff 106 with a plurality of creases, other aspects may comprise an elastic used to retain the cover 104 on the light bulb 102.
Although the aspects described herein have a larger diameter 252 at the installation end 204 than the removal end 206, other aspects may have the larger diameter at the removal end 206 than the installation end 204. In some aspects, the removal end 206 and the installation end 204 may have similar diameters. The diameters of the ends 204, 206 may be determined, in part, by the diameter 114 and/or type of the light bulb 102.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous changes and modifications will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all such suitable changes or modifications in structure or operation which may be resorted to are intended to fall within the scope of the claimed invention
