Description




BACKGROUND OF THE INVENTION




1) Field of the Invention




This invention relates to hand tools and more particularly to a wrench type of hand tool which includes an illuminating device that is intended to illuminate the operating area to which the wrench is being applied.




2) Description of the Prior Art




Hand tools in the form of wrenches have long been known. The common form of wrenches is what is termed a ratchet wrench which is connectable to various types of drivers or sockets, the driver or socket of the wrench then to be applied to a fastener or a fastener nut for the purpose of tightening the fastener or fastener nut. Many times when the operating of these wrenches, the fastener or fastener nut that is being tightened is not only in an inaccessible location but is also in a darkened location. It is common in such locations for the user to operate by “feel” in obtaining of the connection between the wrench and the fastener or the fastener nut as opposed to using sight. In some instances, “feel” is even difficult and sight is an absolute requirement. In such instances, usually there is a second person involved that operates a flashlight to illuminate the area of operation so that a satisfactory job of tightening the fastener or fastener nut can be achieved.




SUMMARY OF THE INVENTION




A primary objective of the present invention is to construct a wrench within which is incorporated a flashlight with this flashlight to be used to illuminate the area that is being operated on by the wrench.




Another objective of the present invention is to construct a wrench which includes a flashlight where the light emitting head of the flashlight can be adjusted to different positions.




Another objective of the present invention is to construct a wrench which includes a flashlight as a separate structure with provision being mounted in conjunction with the wrench to permit detachment of the flashlight from the wrench permitting the flashlight to be used separately.




Another objective of the present invention is to construct a wrench which includes a flashlight which can be manufactured at a reasonable cost and thereby sold to the ultimate consumer at a reasonable cost.




Another objective of the present invention is to construct a wrench which can be used to illuminate darkened areas thereby eliminating the need for a second person to use a flashlight to illuminate the area of operation.




A wrench which has an operating end to which is attached an elongated handle. The elongated handle includes an elongated pocket. The handle also includes a through opening. The body of a flashlight is to be mounted within the pocket with the light emitting head of the flashlight connecting with the through opening.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring particularly to the drawings, there is shown the wrench


10


of this invention. The wrench


10


has an operating end


12


and a handle


14


. The operating end


12


will normally include some form of a ratchet mechanism which is to be operated by pivotable lever


16


which is deemed to be conventional. However, it is not mandatory for the operating end to include the latching mechanism. Typically, the operating end


12


will include a polygonal-shaped protrusion


18


which is designed to connect with an extension rod, a driver or a socket


20


. It is to be understood that the socket


20


or driver is to be used to connect to a fastener or fastener nut which is then to be tightened by usage of the wrench


10


. The fastener or the fastener nut is not shown.




The operating end


12


is integrally connected to the handle


14


. However, as far as this invention is concerned, it is immaterial whether the operating end


12


is integrally connected to the handle


14


and could comprise two separate parts which are interconnected together. The handle


14


includes an elongated pocket


22


. The forward end of the pocket


22


connects with a through hole


24


. The forward end of the through hole


24


includes a relieved portion


26


. The through hole


24


connects between the upper side


28


and the lower side


30


of the handle


14


.




A flashlight which has a flashlight body


32


and a light emitting head


34


is designed to be mountable within the pocket


22


with the light emitting head


34


connecting with the through hole


24


. The rear end of the body


22


is closed by an end cap


36


. The end cap


36


is intended to close battery compartment


38


of the body


32


. Within the battery compartment


38


is to be located a plurality of conventional batteries


40


. The forward end of the body


32


is bifurcated forming a center slot


42


. The protrusion


44


, which is integral with the light emitting head


34


, is mounted within the center slot


42


. Pins


46


and


48


are mounted within the bifurcated portion of the body


42


and are to connect with the protrusion


44


resulting in the light emitting head


34


being pivotally mounted relative to the body


32


. The amount of pivotable movement of the light emitting head


34


is limited to about forty-five degrees. The light emitting head


34


can be adjusted at various angles in order to direct light either closer to the operating end


12


or a little bit further away from .The operating end


12


. In other words, if the wrench


10


of this invention is being used with the socket


20


, then the light emitting head


34


is located in the position of

FIG. 3

to direct the light very near the operating end


12


and actually to illuminate the socket


20


and the adjacent area. The relief portion


26


is included so as to not block this illumination. However, if the operating end


12


is connected to a longer tool, such as an extension or a driver, which will mean that the operation on the fastener or fastener nut is at some short distance spaced slightly further from the operating end


12


, the light emitting head


34


can be adjusted to illuminate that particular area with this adjusting being achieved by pivoting of the light emitting head


34


in a further clockwise direction from the position shown in FIG.


3


. It is to be noted that the light emitting head


34


includes a rounded section


50


to facilitate this pivoting action. The light emitting head


34


also includes a right-angled wall


52


which is to abut against the body


32


when the light emitting head


34


is in substantial alignment with the body


32


.




It is to be understood that the flashlight included within this invention can be removed from the pocket


22


. In order to achieve this removal, there is utilized a latching cover


54


which is basically in the shape of a half circle and at one end thereof, is connected to pivot pins


56


and


58


. The pivot pins


56


are mounted within the handle


14


. The latching cover


54


has a forward end which has serrated sections


60


which facilitate manual grasping of the forward end of the latching cover


54


. The forward end of the latching cover


54


also includes a pair of oppositely facing protrusions


62


and


64


. The protrusions


62


and


64


are to connect with indentations formed within the handle


14


.




With the flashlight mounted within the pocket


22


and the latching cover


54


in the solid line position shown in

FIG. 2

, the flashlight is securely latched in position relative to the handle


14


. However, upon manual grasping of the serrated section


60


and squeezing of such, the protrusions


62


and


64


will disengage from their respective indentations and permit the cover


54


to be pivoted to the dotted line position shown in FIG.


2


. This will permit the flashlight, composed of the body


32


and light emitting head


34


, to be disengaged from the pocket


22


with the flashlight to then be used independently of the wrench


10


.




The protrusion


44


includes a through hole


66


through which is conducted electrical connector


68


. This electrical connector


68


is to make the electrical connection between the batteries


40


and the lamp, which is not shown, and mounted within the light emitting head


34


.




It is to be noted that the body


32


of the flashlight is intended to be mounted in only one position within the pocket


22


. This position is so that the pivot axis of the light emitting head


34


is located parallel to the planes of the upper side


28


and the lower side


30


which are also located parallel to each other. The body


32


may be formed of a slight elliptical shape with only the narrow dimension of the body


32


permitting mounting of the body


32


in conjunction with the pocket


22


thereby insuring that the body


32


is correctly positioned within the pocket


22


. If per chance the body


32


is installed in a reverse direction, which means that the light emitting head


34


would only be able to shine light in the area of lever


16


, the user is then to physically pick up the flashlight and reverse same one hundred eighty degrees and reinstall such within the pocket


22


.
