Abstract
A worklight mounting system having a post extending from a support and a light having a catch. The post is insertable into the catch and is releasably secured within the catch by the coaction between a groove and at least one roller. The coaction there between prevents axial movement while permitting rotational movement there between.
Description




BACKGROUND OF THE INVENTION




The invention relates to a quick mounting system for use with a work light. More specifically, the invention relates to a mount which releasably affixes a light housing to a support structure such as stand, clamp, or other support means.




SUMMARY OF THE INVENTION




In the work light field, there are many types of halogen work lights with several common ones, being a stand light, a portable floor light, and a clamp light. A stand light, as the name suggests, uses a stand to elevate a light housing, in most instances, several feet off the ground for use. A portable floor light, on the other hand, is often placed upon a floor through the use of a base or legs which typically elevate the light no more than several inches off of the floor. A clamp light has a light housing affixed to a clamp which, in turn, may be affixed to a wide variety of objects.




The present invention provides a mounting system which allows a typical light housing to be quickly and easily mounted to any number of different support structures such as a stand, base, legs, clamp, and the like. The mounting system does this by providing a post which has a groove on the support structure. The light housing, in turn, includes a bracket which has a catch. The catch is adapted to releasably engage the post for ease of mounting and dismounting.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Set forth below is a description of what are currently believed to be the preferred embodiments or best examples of the invention claimed. Future and present alternatives and modifications to the preferred embodiments are contemplated. Any alternates or modifications in which insubstantial changes in function, in purpose, in structure or in result are intended to be covered by the claims of this patent.




As shown in

FIG. 1

, the present invention provides a bracket or frame


10


to which a light housing


12


(shown partially in phantom) may be secured by fasteners


14


. Also included on frame


10


is a catch


20


which is adapted to releasably engage a post


30


which is located on a support


32


which may be a pole which extends upwardly from stand (not shown), a clamp, a support base, or some other suitable support to which the light housing may be affixed. Post


30


includes a groove


34


.




Catch


20


includes a cap


21


, interior spring


22


, and outer housing


23


defining a sleeve


24


having bore


25


and inwardly directed finger


45


. Coaxially located within bore


25


is second sleeve


26


which defines a second bore


27


which is adapted to receive post


30


. Sleeve


26


is mounted to bracket


10


and includes an aperture


40


in which roller


42


rests.




In use, light housing


12


is mounted to support


32


by inserting post


30


into bore


27


located in catch


20


. As shown in

FIG. 3

, post


30


is inserted until roller


42


, which is urged inwardly by finger


45


, engages groove


34


. The engagement is maintained by spring


22


which is urged against cap


21


and finger


45


and maintains finger


45


in the proper spatial relationship with respect to roller


42


. Roller


42


only partially extends through wall


47


of sleeve


26


and is prevented from passing through aperture


40


since the inner diameter of aperture


40


is sized to be less than the diameter of roller


42


.




By urging roller


42


against and into groove


34


, axial movement is prevented by the coaction between the roller and groove while rotational movement is still allowed for the positioning of the light on an object to be illuminated. In addition, a plurality of rollers may be used as well for ease of rotational movement.




To disengage worklight


12


from support


32


, roller


42


is released from its engagement with groove


34


. To do this, outer sleeve


23


is actuated in a manner to remove finger


45


from its engagement with roller


42


. This causes roller


42


to travel downwardly on sloped surface


50


away from and out of groove


34


. Once roller


42


clears groove


34


, the light may be disengaged from the support.




As shown in

FIGS. 6 and 7

, the location of the groove and roller may be switched. As shown, catch


60


defines a bore


64


in which groove


62


is located. Post


70


, on the other hand, may include thereon rollers


72


and


74


which partially extend from the post and are adapted to be depressed into post


70


. In use, coaction between groove


62


and rollers


72


and


74


is similar to the groove/roller engagement described above. As post


70


is inserted into bore


64


, rollers


72


and


74


are urged inwardly until they coact with groove


62


. Then, the rollers spring outwardly to inhibit any further axially movement while permitting rotational movement as described above.




It should be understood that various changes and modifications to the preferred embodiments described would be apparent to those skilled in the art. Changes and modifications can be made without departing from the spirit and scope of the present invention and without diminishing its intended advantages. It is, therefore, intended that such changes and modifications be covered by the following claims.



Claims
  • 1. A worklight mounting system comprising:a post extending from a support having a groove; a light housing having a catch having an internally located at least one roller; and said groove and said at least one roller coact to releasably engage said post to said catch, said coaction prevents axial movement between said post and said catch while permitting rotational movement there between.
  • 2. A worklight mounting system comprising:a post extending from a support, said post having a groove; a light housing including a catch, said catch comprised of coaxially aligned inner and outer sleeves; at lease one aperture on said inner sleeve and at least one roller disposed therein, said aperture including a surface which is directed downwardly towards said outer sleeve; a bore defined by said inner sleeve, said bore adapted to receive said post; a finger on said outer sleeve, said finger adapted to urge said roller against said groove to permit said roller and said groove to coact to secure said post within said catch; and said outer sleeve adapted to be actuated, said actuation releases said finger from engaging said roller which permits said roller to be disengaged from said groove whereby said catch and said post may be separated.
  • 3. The device of claim 2 further including a spring, said spring maintains said finger in a position to urge said finger against said roller.
  • 4. A worklight mounting system comprising:a post extending from a support; at least one roller partially extending outwardly from said post; a light housing having a catch, said catch defining a bore adapted to receive said post and a groove adapted to coact with said roller; said coaction between said roller and said groove releasably secures said post within said catch while permitting said catch to rotate about said post.
