Abstract
A portable worklight having a protective outer casing which encloses the contents of the light. The outer casing includes first and second housings which are operable between open and closed positions. When in a closed position, the working components of the light, including the lens, grill, and light source are enclosed by the two housings. In an open position, the second housing acts as a base which holds the worklight in an upright position.
Description




BACKGROUND OF THE INVENTION




The invention relates to portable worklights, and more specifically, a portable worklight that includes an outer protective housing.




SUMMARY OF THE INVENTION




Typical worklights consist of a light housing which typically contain the components necessary to illuminate an object. This would include, among other things, a lens, grill, light source or lamp, and the necessary wiring and electrical components. In addition, a tubular support stand often is used to support the light housing in an upright position. However, because the worklights are intended to be portable, the worklights are often transported in vehicles and the like along with other equipment. As a result, the worklight is susceptible to damage when being transported, especially the light source and lens which mare made of glass and remain exposed to damage from foreign objects. In addition, while the common support stand is useful when the light is in a stationary position, in a moving vehicle it typically fails to support the device in a stable condition.




The present invention minimizes the risk of damage during transportation by providing a worklight having opposing first and second housings which enclose the worklight when in a closed position and which hinge open for use. Moreover, the housings have at least one flat surface that supports the light housing in an upright position during use and in a stable position when being stored and/or transported.




Consequently, an object of the present invention is to provide a worklight which incorporates a protective housing as part of the light.




Another object of the present invention is to provide a first housing that contains the light source and an opposing second housing that acts as base.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




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.





FIG. 1

shows a worklight


10


having a first housing


12


and second housing


14


both of which define a cavity. Located in the cavity of housing


12


are the components making up a standard light, i.e., a lens


17


, light source


18


, grill


20


, and front plate


21


as well as the necessary wiring and electrical components (not shown)among other things.




The housings are connected together by hinges


22


and


24


as shown in

FIG. 1

or hinge


100


as shown in FIG.


7


. As shown in

FIGS. 2 and 3

, hinges


22


and


24


form two pivot points


33


and


37


with housings


12


and


14


.




Spring latches


38


and


40


coact with edges


61


and


63


to releasably secure the housings together. Hinges


22


and


24


include latches


34


and


36


which releasably secure the hinges in a stationary position during operation of the light source and permit the rotation of the hinges when released. Coacting fasteners


30


and


32


pivotally connect housing


12


to hinges


22


and


24


as well.




In use, worklight


10


is stored and transported in a closed position as shown in FIG.


5


. In this position, the grill, light source, and lens are all enclosed by the housings and are inaccessible to foreign objects which would damage the components. In addition, the flat surface


19


of housing


14


holds the device in a stable position which further minimizes the risk of damage to the device. When the light is needed to illuminate an object, latches


30


and


40


are operated to release the housings which allows housing


12


to pivot about pivot point


33


. This allows housing


12


to move forward as well as up and away from housing


14


and into a position located above the central portion of housing


14


until latches


38


and


40


catch and hold hinges


22


and


24


in a stable, extended position. This, in turn, raises the grill and other operating components of the light out of the cavity formed by housing


14


. Next, housing


12


is pivoted about fasteners


30


and


32


until a desired position of illumination is obtained. At the same time, housing


14


functions as a base to hold the light source in an upright position.




Moreover, placing pivot points


33


and


37


offset from the center line


39


, as shown in

FIGS. 2 and 3

, permits housing


12


to remain centrally located with respect to housing


14


. This maintains the balance of the device when it is in an open position which helps prevent tipping. It also allows the components in housing


12


to nest within housing


14


. Because the components must be centrally aligned to nest within housing


14


, as shown in

FIGS. 2 and 3

, to close the device, pivot point


37


which is located on the lower end of housing


37


, is positioned to coordinate with the length of the hinges to place the outer of edges of the two housing together when in a closed position.




In an alternate embodiment, a single pivot point is used to connect housing


102


to


104


. The construction and operation of this embodiment is similar to the embodiment 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 portable worklight comprising:first and second housings, said housings pivotal between open and closed positions; a lens, light source, and grill located on said first housing; in said closed position, said lens, grill, and light source are enclosed by said housings; and in said open position, said second housing acts as a base which holds said worklight in an upright position.
