Abstract
A work light stand. The stand includes a stand having a cross bar and at least one work light. The work light is installed on the cross bar of the stand by a universal direction adapter positioned at a fixed angle of elevation, and which can be oriented towards any direction such that adjusting the light emitting direction can be achieved by adjusting the work light itself directly.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




This present invention relates to a work light stand; especially to a work light stand capable of adjusting the light emitting direction of the work light.




2. Description of the Prior Art




Work lights are used extensively in many night work settings. For convenience, the conventional work light is generally installed on a stand. Shown in

FIG. 1

is a work light stand


10


that comprises a stand


11


, a cross bar


12


and a work light


14


; a U-shape adjuster


1


, hinged to the cross bar


12


of the stand


11


, can adjust the direction of light emitted from the work light


14


mounted on the cross bar


12


. The two arms of the U-shape adjuster


1


are fastened to the two protruding edges at the bottom of the work light


14


. A screw


4


fastens the U-shape adjuster


1


at the center of its bottom side to the cross bar


12


.




However, under the prior art, adjustment of the light emitting direction requires at least two steps: first, the screw


4


fastening the U-shape adjuster


1


to the cross bar must be unwound so that the work light can be adjusted in the horizontal direction, after which the screw


4


is wound up to fasten the work light


14


in a fixed horizontal direction. Secondly, the screws


2


and


3


fastening between the U-shape adjuster


1


and the work light


14


are unwound so that the work light


14


's angle of elevation can be adjusted, after which the screws


2


and


3


are again wound up to secure the work light


14


in its elevation angle. As the above indicates, the conventional work light stand


10


involves redundant steps when adjusting the light emitting direction of the work light


14


, causing inconvenience to a user. Furthermore, when adjusting the horizontal direction and the angle of elevation, the user must use one hand to hold the work light


14


in place while using the other hand to wind up the screws


2


,


3


, and


4


, a process that is laborious and time-consuming. In light of the above, the present invention furnishes a work light stand that provides easy adjustment of its light emitting direction, which thus has industrial practicality and utility.




The primary object of the present invention is to furnish a work light stand, which does not require unwinding of its screws in order to adjust its work light's emitting direction, thus making the work light stand convenient to use.




Another object of the present invention is to furnish a work light stand, which allows the user to simultaneously adjust the work light's horizontal direction and the angle of elevation when adjusting its light emitting direction, making the operation timesaving.




A further object of the present invention is to furnish a work light stand, which includes a universal direction adapter to adjust the work light's emitting direction.




SUMMARY OF THE INVENTION




Under the prior art, adjusting the work light stand to change the work light's emitting direction is laborious and time-consuming, and the repetitive process is inconvenient to the user. In light of such drawbacks in the prior art, the present invention provides a work light stand that comprises a stand, a cross bar and a work light. The work light is installed on the cross bar via a universal direction adapter so that the user can adjust the work light itself to change the light emitting direction.

DETAILED DESCRIPTION OF THE INVENTION




First, as shown in

FIG. 2

, the work light stand of the present invention


10


comprises a stand


11


having a cross bar


12


and supporting legs


13


and at least one work light


14


. The work light is installed on the cross bar


12


via a universal direction adapter


15


consisting of two hinged position fixers


151


and


152


. The first position fixer


151


and the second position fixer


152


can fix each other's position in relation to any direction, so that when adjusting the light emitting direction, the user can adjust the work light


14


itself through the employment of the universal direction adapter


15


, to simultaneously fine-tune both the horizontal direction and the angle of elevation. The structure of the universal direction adapter


15


is further described hereunder.




The universal direction adapter


15


has a wide range of applications, and generally comprises the first position fixer


151


and the second position fixer


152


as shown in FIG.


3


. The first position fixer


151


is hinged to the second position fixer


152


, and because of the friction force between the two fixers, any angle of elevation can be securely held. A turntable


153


, underneath the second position fixer


152


, enables the second position fixer


152


to be rotated in the horizontal plane. Therefore, with the universal direction adapter


15


employed in the work light stand


10


of the present invention, the work light


14


can be mounted on the first position fixer


151


, and the turntable


153


of the second position fixer


152


can be mounted on the cross bar


12


of the stand


11


, so that when adjusting for a new light emitting direction, regardless of its initial orientation, the work light


14


itself can be adjusted towards the desired emitting direction, and the universal direction adapter


15


between the work light


14


and the cross bar


12


will yield to the adjustment in both the horizontal direction and the angle of elevation, thus holding the work light


14


securely in the desired direction.




Moreover, a handle


16


, installed on the work light


14


, enables the user to hold on to it when adjusting the work light


14


and turn the universal direction adapter


15


upward or downward about its central axle, so that the adjustment in both the horizontal direction and the angle of elevation is completed in one action. After the user releases the handle


16


, the friction force in the universal direction adapter


15


itself can hold the work light


14


in position of the desired emitting direction.




The above thorough description of the preferred embodiment of the present invention can be clearly grasped by a person skilled in this technical field, who can then undertake various modifications without departing from the scope and spirit of the claims hereunder. In addition, the present invention is not limited to the specific mode of embodiment described herein; for instance, the universal direction adapter


15


is not limited to any specific structure; any functionally equivalent universal direction adapter


15


can be used to connect between the work light


14


and the cross bar


12


.




The work light stand of the present invention overcomes the drawback associated with the prior art in which the U-shape adjuster fixes the work light in position with screws, such that the work light cannot be adjusted in the horizontal direction and the angle of elevation simultaneously for easy operation. Therefore, the work light stand of the present invention employs the universal direction adapter for directional adjustment of the work light, where no screws are used and that allows the user easy adjustment.



Claims
  • 1. A work light stand device comprising:a stand; a crossbar secured to the stand; a universal direction adapter comprising first and second position fixers that are frictionally hinged to one another, and a turntable which is rotatably secured on a horizontal plane between the crossbar and the second position fixer; a work light secured to the first position fixer; the universal direction adapter supports the weight of the work light secured to the first position fixer thereof; and adjustment of the position of the work light towards any direction is made by manually rotating the position between the first and second position fixers upon which the first and the second position fixers are frictionally locked, as well as rotation of the turntable.
