Abstract
TOOL FOR REMOVAL AND REPLACEMENT
OF LIGHT BULBS
ABSTRACT OF THE INVENTION
A tool for the removal of a light bulb from a remote socket consists of a flexible cup fitted over one end of a hollow rod.
The other end of the rod is fitted to a flexible elastomeric bellows adapted to expel its inner air through the cup to allow any object such as a light bulb to be gripped by the cup surface when the bellows is released.
OF LIGHT BULBS
ABSTRACT OF THE INVENTION
A tool for the removal of a light bulb from a remote socket consists of a flexible cup fitted over one end of a hollow rod.
The other end of the rod is fitted to a flexible elastomeric bellows adapted to expel its inner air through the cup to allow any object such as a light bulb to be gripped by the cup surface when the bellows is released.
Description
~ ~ TOOL FOR REMOVAL AND REPLACEMENT OF LIGHT BULBS
2~6898~
FIELD OF INVENTION
The present invention discloses a flexible member held aloft on a rigid hollow rod for enclosing a light bulb within its socket. By imp~rting a twisting motion to the rod, an operator standing below the bulb with the flexible member surrounding the bulb, can unscrew the bulb from its socket in an overhead fixture.
.
PRIOR ART
In industrial sites where overhead light bulbs are in use and where long step ladders are awkward to use, a cage-like device held on a long rod has been used to enclose the bulb and~
is used to impdrt the twisting action for removal of the bulb.
A cushion material i5 often fitted to the inner sides of the claws of the cage to prevent breakage of the glRss of the bu]b when being removed or replaced.
It is known that many household accidents are caused by people climbing on chairs or ladders to reach objects otherwise out of their reach from a floor surface. It is known that many light fixtures are difficult to access without the use of a ladder or climbing assist such as a chair. For old people the danger of climbing to change light bulbs is very great and with the recent design of apartments specifically made for older people with saftey in mind, the need for a tool to easily change a light bulb for a fixture has become apparent.
r OBJECT OF THE INVENTION ~ 0 ~ ~ ~ 8 3 The principal object of the invention is therefore to provide a tool having a flexible member thereon to surround a light bulb and which when twisted on t.he bulb will unscrew it from the fixture. Another object of the invention is to position the flexible member on a pole thereby allowing a person to use the flexible member from a position remote from the bulb. Another object of the invention is to use a hollow rod or pole with the inner body of the flexible member having and opening therein.--:
I`he flexible member is adapted to interfit over one hollow end of the rod to allow air passage between the rod and the flexible member.
A bellows member is adapted to interfit over the lower end of the hollow rod to permit the passage of air into and from the hollow rod.
SUMMARY OF THE INVENTION
A tool for the removal of a light bulb consists of an elastomeric flexible cup adapted to interfit over the roundecl portion of a light bulb and has an opening therein fixed over one end of a hollow rod. A bellows is fixed to the other end of the hollow rod to allow passage of air therethrough to and from the flexible cup. The inner face side of the flexible cup has a soft elastomeric surface thereon to grip the surface of the light bulb.
OPERATION OF THE DEVICE
To remove a light bulb wi~h the device, the bellows is depressed to expel the air from it and after the cup has been fitted over the bulb the bellows is allowed to return to normal .~ :
2~8983 -l~ereby a vacilum effect is created in the system and in the space between the cup and the rod opening thereby helping to pull the bulb into engagement with the gripping surface of the cup. The rod i9 then twisted until the bulb threads are freed from the socket and the tool and bulb combination can be lifted away from the socket without the bulb falling out of the cup. To replace a bulb it is placed into the cup while the bellows is depressed and then the bellows is released to impart a vacuum assist to the gripping action of the cup surface. The combination, tool and bulb, is then lifted to the socket where, by twisting the rod, it is screwed into place. When the bulb is in place in the socket the bellows is depressed to break the vacuum and thereby releases the cup from the bulb.

With the foregoing objects in view and such advantages or novel features as may become apparent from consideration of this disclosure and specification the present invention consists of the concept which is comprised, embodied and embraced and included in the methods or use of the methods and arrangements, or any new use of the foregoing, herein exemplified in the specific embodiment of the concept, reference being had to the accompanying drawings.
Figure 1 is a view of the tool in use showing the cup in section over a bulb and attached to the rod of the device.
Figure 2 is a perspective bottom view of the flexible cup attached to a rod and shows the rough inner gripping surface of the flexible cup .

THE PREFERRED EMBODIMENT OF THE INVENTION
Numeral 10 in Figure 1 designates the tool of the invention shown in engagement with a light bulb 15 by the gripping ac-tion of the elastomeric cup 13 as shown also in Figure 2 where the inner surface of cup 13 is roughened as at 20 to grip the smooth outer surface of the bulb 15. The cup 13 tapers to a hollow opening where it is fixed to a hollow rod 12 in a funnel-like configuration.
The hollow rod 12 is open at both ends with the one end aE~resaid fitted to the cup and the other end open and fitted to an opening into the interior of a flexible rubber bellows 14. Squeezing of the bellows 14 will expel air out through rod 12 and when the bellows is released after the bulb is fitted to cup 13 a vacuum like action is created to hold the bulb 15 into engagement with cup 13. The bulb 15 is shown in Figure 1 threaded at 17 into a socket 16 which is fixed to a wall or ceil-ing.
