Abstract
A socket set includes a socket wrench having a tapered hollow handle. A tapered tray fits within said handle. The tapered tray holds a plurality of sockets resting on their sides. This enables one to combine the socket set with the wrench so the sockets are always present when needed.
Description




BACKGROUND OF THE INVENTION




Socket wrenches, also referred to as ratchet wrenches, have a rectangular drive to rotate a socket which engages a nut or bolthead causing it to rotate A plurality of sockets are used, each socket having a different size opening to fit a different size nut or bolt. The drive for all the sockets is the same. Generally the sockets are stored separate from the wrench.




However, there are many different types of socket wrenches which have been used which hold or house a plurality of sockets. None of these are particularly efficient. Either they lose a great deal of torque in the design of the overall wrench or the location of the sockets is very inconvenient.




For example, in Martinmaas, U.S. Pat. Nos. 4,253,356 and 4,352,306 disclose a socket set in which the sockets are held in an open handle of the wrench. When one grasps the wrench, they actually grasp the sockets which is particularly uncomfortable and would prevent one from applying a great deal of torque. Lin, U.S. Pat. No. 4,627,315 discloses a wrench socket combination in which the sockets are held in a tray. However the sockets are held in an upright position making the size of the handle very awkward and thus difficult to use.




SUMMARY OF THE INVENTION




The present invention is premised on the realization that a socket wrench having a socket wrench and a set of sockets can be formed wherein the socket wrench simply has a tapered hollow handle which is adapted to hold a plurality of sockets laying on their side and supported in a tray which is also tapered and adapted to fit within the handle. A cap is placed at the end of the handle to hold the tray and the sockets in position. Preferably the tray has a plurality of pairs of fingers which are adapted to grasp the sockets positioned on the tray leaving enough room for an individual to grasp the socket to remove it from the tray. Thus, the present invention is easy to use. It keeps the sockets together and most importantly the socket wrench itself is not so altered as to make it difficult to use.




The objects and advantages of the present invention will be further appreciated in light of the following detailed description and drawings in which:

DETAILED DESCRIPTION




As shown more particularly in

FIG. 1

, the present invention is a socket wrench set


12


. The set


12


includes a socket wrench


14


which has a handle


16


and a ratchet drive mechanism


18


. The set also includes a plurality of different sockets


22


which are stored together in a plastic tapered tray


24


which fits within the hollowed portion


26


of the handle


16


. In turn this is maintained in the handle


16


by a plastic cap


28


which is threaded into an open end


32


of the socket handle


16


.




More particularly as shown in the present invention, the tapered handle


16


of socket wrench


14


terminates in a neck


34


which connects to the drive mechanism


18


in the head


36


of the socket wrench


14


. Each of the sockets


22


in turn has an opening which corresponds to the size of drive


38


as is typically the case with socket wrenches.




Each of the different sockets has a different diameter permitting them to be stacked on their sides and positioned in the tray


24


. (See

FIG. 2.

) Thus the socket with the smallest cross-sectional diameter is in a front portion


42


of the tray whereas the socket with the largest cross-sectional diameter is in the rear portion


44


of the tray and the remaining sockets are positioned based on size from front to back. The handle


16


further includes a rubber or plastic grip


46


which encases the outer portion of the handle making it easier to grip.




As shown in

FIG. 3

, the tray


24


has a rounded tapered lower portion


48


. The lower portion is arcuate and is preferably less than 180° radius so that the lower portion is not actually holding the individual sockets. The bottom


49


of the tray is flat so that when the tray itself is removed from the handle, it will rest on a flat surface without rocking. Extending from the bottom portion which is slightly tapered (from bottom to top) are pairs of fingers


52


. Each pair of fingers is adapted to grasp one of the sockets so that again the pair of fingers at the front end


42


of the tray


24


are closest together designed to grasp a small socket and the pair of fingers at the far end


44


of the tray


24


are farthest apart adapted to grasp the largest socket. Again the remaining fingers are positioned accordingly to grasp the different size sockets.




When the socket wrench is not being used, the sockets will be snap-fitted on their sides in the tapered tray


24


and positioned in the hollow portion of the handle


16


. The cap


28


will close the end of the handle keeping the tray


24


in position. When the socket set is needed, cap


28


is pulled off and the tray


24


pulled out and the necessary socket


22


removed from the tray


24


. This will then be put on the drive


38


of the socket wrench


14


and used. When finished, the socket


22


would be placed back in the tray


24


, the tray back in the handle and the socket wrench will be ready for storage with all the sockets very neatly held within the wrench.




Thus, the present invention provides a very unique way to hold the sockets with the socket wrench. But most importantly it does not cause an extreme deviation of the shape of the socket wrench. Thus it basically has the same feel as a normal socket wrench because of the shape of the socket handle i.e., tubular.



Claims
  • 1. A socket set comprising a socket wrench having a tapered hollow handle and a cap sealing a large end of said handle;a plurality of sockets each having a round side surface and having a different outermost diameter and adapted to snap onto said socket wrench; said sockets located axially aligned within an interior portion of said handle.
  • 2. The socket set claimed in claim 1 wherein a smallest socket is located nearest a forward end of said handle and a largest socket is located nearest said cap.
