Cleanable reversible socket and driver

Abstract

A cleanable reversible socket and driver for a hex head fastener having a driver shank with a hex shaped shaft, or otherwise splined, having a tool mounting end and a socket mounting end and a collar therebetween. A cleanable reversible socket is provided having a hex, or otherwise splined, passage therethrough rotationally lockable with the similarly shaped driver shank shaft. The socket is removably, nonrotatably mountable onto the driver shank shaft at the socket mounting end up to the collar having two different sized hex socket ends. A magnet on the socket mounting end of the driver shank is to be located at a bottom of one of the two hex socket ends when the socket is mounted on the driver shank to hold the hex head fastener in one of the socket ends.

DETAILED SPECIFICATION

(13) Referring to FIGS. 1 through 3, the cleanable reversible socket and driver 10 for a hand tool may be seen and appreciated. The socket and driver 10 includes a drive shank 12 that will fit on to a multipurpose driver handle 17 with spring loaded retaining balls. The drive shank 12 will also removably receive and hold a socket or drive sleeve 32.

(14) More particularly, the drive shank 12 may be of various lengths depending on its particular use. The shank 12 has a hex shaped shaft 14. Other spline configurations are possible. At the tool mounting end 18 is located an intermediate annular channel 16 that may be gripped and held by the spring loaded retaining balls 17.5 of the driver handle 17. Intermediate of the hex shaft 14 or drive shank 12 is an annular collar 20. Forward of and adjacent to the collar 20 is raised stop ring 22, both of which will be appreciated later. Adjacent to the socket drive end 24 is located spring loaded retaining ball or detent 28. At the drive end 24 is imbedded magnet 26.

(15) The cleanable removable socket or drive sleeve 32 has a round exterior 36 and an internal through passage 38 which is hex shaped to engageably match the hex shaped drive shank 12 and shaft 14. Other spline configurations are possible. By this arrangement, the tool handle 17 may transmit rotational torque to the shaft 14, shank 12 and ultimately to the socket or drive sleeve 32 for turning in an hex screw or fastener 44 into a work piece.

(16) The socket 32 has first and second internal hex ends 40, 42. The smaller hex end 40 is of equal size or larger than the hex size of the hex shaped shaft 14 and the socket drive end 24. The larger hex end 42 is of a larger size than the hex size of the hex shaped shaft 14 and the socket drive end 24. The hex sizes of the shaft and hex ends may vary, such as, from , , 7/16 or 5/16 inch. Within internal passage 38 are located first and second internal grooves or channels 46, 48 for axial locking of the spring loaded retaining ball or detent 28 on shank 12 depending on which side, first or second socket ends 40, 42 are to be used.

(17) The assembly and operation of the cleanable reversible socket and driver 10 with hand tool 17 may now be appreciated and understood, particularly in FIGS. 1, 4 and 5. The drive shank 12 is grasped and the tool mounting end is fed into the receptacle end of the hand tool 17 until the annular channel 16 snaps into engagement with the spring loaded retaining balls 17.5. Next the desired size of socket 32, such as internal hex end inch 42, is selected. The opposite hex end 40 ( inch) is fed onto hex shaped shaft 14 until the spring loaded retaining ball or detent 28 on shaft 14 is engaged with second internal groove or channel 48 which will axially lock the socket 32 onto the shaft 14 as the outer surface of hex end 40 ( inch) will abut against the raised stop collar 22. The handle 17 may be replace with the tightening chuck of a drill or a ratchet tool.

(18) Now the cleanable reversible socket and driver 10 may be used by an operator. The inch hex head of a hex screw 44 or bolt or other fastener is lined up with the inch hex end 42 of the socket 32. The magnet 26 at the base of hex end 42 will suck up and draw in the inch hex head of the fastener 44 and hold it thereat. The operator simply points the fastener 44 into the work piece and transmits the rotation torque to secure the fastener into the work piece. After many, many uses of the inch hex end 42, the socket hex end 42 becomes clogged with filings, shavings and metal particles to the point where the fastener has difficulty in fitting into the inch hex end 42.

(19) When the hex end 42 becomes clogged, the operator may simply pull the socket 32 off the hex shaped shaft 14 by overcoming the grip of the detent 28 in groove 48. Because the socket is not magnetized, the debris may simply be blown out (with a large breath) of the socket 32 through internal passage 38 or tapping the socket 32 on a hard surface. The magnet end 24 of the shaft may simply be wiped off with a rag to remove the particles.

(20) Thereafter the socket 32 may be reassembled onto the shaft 14 or reversed to present the inch socket hex end 40 for use by the operator. Other socket 32 sizes may be contemplated for use. all that is necessary is that the hex shaped shaft 14 of the drive shank 12 be of a size compatible with the hex shaped internal passage 38 or the socket 32 to guarantee compatible rotational torque being transmitted through the parts.

(21) Referring to FIG. 6, a second embodiment of the drive shank 112 may be viewed that is similar to drive shank 12 and shaft 14 of the first embodiment. Shank or shaft 112 has an annular collar or socket stop 120. Next to the collar 120 is fixed a ring magnet 128 that hold the cleanable removable socket 130 in place.

(22) Referring to FIGS. 7 and 8, a third embodiment of the drive shank 136 may be viewed that is similar to drive shank 12 and shaft 14 of the first embodiment. Shank or shaft 136 has an annular collar or socket stop 138. A socket drive end 140 has an annular channel 142 with an expansion ring 144 seated therein. The cleanable socket 146 has an interior annular channel 148 that releasably engages the expansion ring 144 to hold the socket 146 in its drive position.

(23) Referring to FIGS. 9 and 10, a fourth embodiment of the drive shank 152 may be viewed that is similar to drive shank 12 and shaft 14 of the first embodiment. Shank or shaft 152 has an annular collar or socket stop 154. A socket drive end 156 has an annular channel 158. The cleanable socket 160 has an exterior annular channel 162 wherein is seated an expansion ring 166 which has radial fingers 168. Fingers 168 engage the annular channel 158 to hold the socket 146 in its drive position.

(24) Referring to FIG. 11, a fifth embodiment of the drive shank 172 may be viewed that is similar to drive shank 12 and shaft 14 of the first embodiment. Shank or shaft 172 has an annular collar or socket stop 174. A socket drive end 176 has an annular channel 178 with an elastomeric and compressible O-ring 144 seated therein. The cleanable socket 146 may or may not have an interior annular channel that releasably engages the compressible O-ring 144 to hold the socket 146 in its drive position by frictional grip.

(25) Referring to FIG. 12, a sixth embodiment of the drive shank 190 may be viewed that is similar to drive shank 12 and shaft 14 of the first embodiment. Shank or shaft 190 has an annular collar or socket stop 192. A socket drive end 194 has an annular channel 196. The cleanable socket 198 has an exterior threaded passageway 200 wherein is threadably seated a threadable spring-ball plunger 202 which releasable engages the annular channel 196 to hold the socket 190 in its drive position.

(26) The above description and FIGS. are for illustrative purposes only. The true scope of this invention is defined by the following claims.
