Abstract
An adjustable socket for engaging various sized fastener projections such as hexagonal nuts, includes a socket body with a cavity having a spring-biased plate pushing nested and concentrically positioned sliding sleeves toward the socket opening and their first position. A retainer member restrains the outer sleeve and offset lower sleeve ends form interlocking shoulders to restrain the inner sleeves. Magnetic strip pairs are between the sleeves and integrated therewith to form magnetic couples when the sleeves are in the first position. The intrusion of a nut will encounter one or more of the smaller sleeves and shear the magnetic coupling between the largest of the smaller sleeves and the next largest sleeve. Magnetic couplings between the larger sleeves are maintained during the downward displacement of the smaller sleeves thus keeping such sleeves in the first position. The sleeve bore shapes can be chosen to engage all shapes of fastener projections.

A multiple sockets wrench which is able to accommodate and twist a great variety of differently sized and shaped nuts, bolts and screws. The wrench includes a polygonal tubular housing and several groups of clamping blocks axially retractably received in a front end of the housing. When used to twist a nut or a bolt head, the nut or bolt head contacts with the groups of the clamping blocks to force the unsuitable contacted clamping blocks into the housing, while permitting the suitable uncontacted clamping blocks to hold the nut or bolt head.




While these socket devices may be suitable for the purposes for which they were designed, they would not be as suitable for the purposes of the present invention, as hereinafter described. In particular, no prior art adjustable sockets use magnetic couples between sliding sleeves to retain the larger sleeves in place as the smaller sleeves are displaced by the intruding nut or bolt head to be wrenched.




SUMMARY OF THE PRESENT INVENTION




A primary object of the present invention is to provide a self-adjusting socket to accommodate different sized nuts and bolt heads without the user having to make any changes or adjustments.




An additional object of the present invention is to provide a self-adjusting socket having a plurality of concentric hexagonal sleeves.




A further object of the present invention is to provide a self-adjusting socket wherein the plurality of concentric hexagonal sleeve are biased towards the open end of the socket by a movable plate and a spring member, the hexagonal sleeves being retained within the socket by a flanged threaded retainer member extending peripherally across a portion of the open end of said socket.




A yet further object of the present invention is to provide a self-adjusting socket wherein the concentric hexagonal sleeves travel independently in response to pressure applied thereto by the insertion of a nut or bolt head.




Another object of the present invention is to provide a self-adjusting socket wherein each hexagonal sleeve employs magnetic strips to magnetically pair with adjacent sleeves, so as to maintain the larger sleeves in their original position while one or more smaller sleeves are being displaced by an intruding fastener projection.




One more object of the present invention is to provide a self-adjusting socket that is simple and easy to use.




A further object of the present invention is to provide a self-adjusting socket that is economical in cost to manufacture.




Further objects of the present invention will appear as the description proceeds.




The present invention is an adjustable socket for attachment to a typical tool handle, that has a plurality of concentric sleeves nested within a socket body cavity, wherein the pressure of a fastener such as a nut or bolt head being applied to one or more of the sleeves will thrust such sleeves longitudinally into said socket body while the larger sleeves, not directly borne upon by the insertion of the nut or bolt head, will remain stationary due to magnetic strip pairs that are positioned between the sleeves and integrated therewith. The magnetic strips are aligned on the sleeves to magnetically couple when the sleeves are in the upper first position. A singular spring member and a movable plate biases the sleeves toward the socket upper body end until a greater opposing bias is introduced by the insertion of the nut or bolt head. A retainer member prevents the plate from moving the sleeves out of the socket body cavity.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




The following discussion describes in detail various embodiments of the invention. This discussion should not be construed, however, as limiting the invention to those particular embodiments. Practitioners skilled in the art will recognize numerous other embodiments as well. For a definition of the complete scope of the invention, the reader is directed to the appended claims.





FIGS. 1-10

depict various views and components of the socket


10


of the present invention.

FIG. 1

depicts the socket


10


attached to a tool handle


12


held in the user's hand


14


.




As shown in

FIGS. 2-4

, the socket


10


has a metal main body


20


, formed about a central axis, the main body


20


having a lower body


22


with a lower end


24


, into which is directed a bore


26


for receiving the driving projection of a tool handle


12


. Typically the driving projection is square, and the bore


26


shown in

FIG. 3

, FIG.


9


and

FIG. 10

is shaped to receive such a projection. As shown in

FIG. 7

, the socket


10


receives and engages various fastener projections


16


such as the hexagonal head nut shown. The invention contemplates adaptation for all fastener projections, including bolt heads, screw heads, nuts, and the like, whether hexagonal, square, or of other polygonal shapes.




An upper body


30


portion of the main body


20


has a threaded upper end


32


for threaded coupling with a ring-shaped retainer member


34


.




Projecting within the main body


20


is a main body cavity


36


. In the preferred embodiments, the main body cavity


36


is hexagonal. In other embodiments, it is anticipated that other shapes will be utilized in order to accommodate a variety of fastener projections


16


, as discussed above. In the lower main body cavity


36


is a spring


38


that is positioned between and against the main body


20


and a hexagon shaped plate


40


, the plate being positioned perpendicular to the center axis of the main body


20


.




A hexagon shaped peripheral sleeve


42


is inserted into the main body cavity


20


, and has an exterior surface


44


that is flush against the main body cavity


36


along the length of the peripheral sleeve


42


. The lower end


46


of the peripheral sleeve


42


rests on the plate


40


. As shown in

FIGS. 3-5

, the upper end


48


of the peripheral sleeve


42


is held flush with the main body upper end


32


, in that the retainer member


34


inside diameter causes the retainer member


34


to overlie the points of the peripheral sleeve


42


hexagon, thus preventing the spring


38


from de-compressing further and elevating the peripheral sleeve upper end


48


above the main body upper end


34


. The peripheral sleeve


42


also has a reduced thickness at the lower end


46


that forms a downwardly facing shoulder


50


on the interior surface


52


of the peripheral sleeve


42


.




Several additional hexagon shaped sleeves


60


, are concentrically nested within the peripheral sleeve


42


. Each sleeve


60


,


70


,


80


,


90


,


100


has a lower end


62


,


72


,


82


,


92


,


102


that is adjacent the plate


40


in the first position, as shown in

FIGS. 3-4

, an upper end


64


,


74


,


84


,


94


,


104


, and an offset that forms an interior downwardly facing shoulder


66


,


76


,


86


,


96


,


106


and an exterior upwardly facing shoulder


68


,


78


,


88


,


98


,


108


, as shown particularly in FIG.


8


. As shown in

FIG. 3

, this arrangement prevents the sleeves


60


,


70


,


80


,


90


,


100


from sliding upwardly relative to the others when in the first position, while allowing downward sliding to a second position when a nut


16


bears upon one or more of them with sufficient force to compress the spring


38


and lower the plate


40


.





FIG. 7

depicts the downward displacement of the innermost and smallest sleeve


100


by a hexagonal nut


16


. The sleeve


100


slides downwardly with respect to the next largest sleeve


90


to the second position. The lower end


102


pushes on the plate


40


and compresses the spring


38


, such that the plate


40


no longer bears upon the remaining sleeve lower ends


62


,


72


,


82


,


92


.




To support such remaining sleeves


60


,


70


,


80


,


90


, pairs of magnetic strips


110


,


112


,


114


,


116


,


118


,


120


are integrated with the sliding sleeves


60


,


70


,


80


,


90


, the peripheral sleeve


42


, and the upper body interior wall


122


, to create magnetic couples between the sleeves


60


,


70


,


80


,


90


, between the outermost sliding sleeve


60


and the peripheral sleeve


42


, and between the peripheral sleeve


42


and the upper body interior wall


122


, as shown in FIG.


4


.




These magnetic attractions are of such a strength that the direct shear force on the magnetic strip pair


110


causes it to separate and allow the innermost sleeve


100


to be displaced downwardly by the nut


16


. The other magnetically coupled pairs


112


,


114


,


116


,


118


,


120


are not separated, thus the remaining sleeves


60


,


70


,


80


,


90


are held in place although the plate


40


has been lowered. Since the innermost sleeve


100


will not need to remain in the first position while the plate


40


is lowered, the magnetic strip pair


110


between the innermost sleeve


100


and the next largest sleeve


90


can be eliminated in another embodiment.




In another circumstance, where the nut


16


corresponds to the size of the third sleeve


80


, the intruding nut


16


bears upon the third sleeve


80


which, in turn, bears upon the two next smallest sleeves


90


,


100


through the interaction of the adjacent shoulders, e.g. the interior downwardly facing shoulder


86


of the third sleeve


80


bearing on the exterior upwardly facing shoulder


98


of the next smallest sleeve


90


, and the interior downwardly facing shoulder


96


of the next smallest sleeve


90


bearing on the exterior upwardly facing shoulder


108


of the innermost sleeve


100


. In this circumstance, magnetic strip pair


114


is sheared, while pairs


116


,


118


,


120


remain magnetically coupled.




In the preferred embodiment, the strength of the magnetic attraction between the magnetic strip pairs


110


,


112


,


114


,


116


,


118


,


120


decreases from the outermost pair


120


to the innermost pair


110


, in order to encourage the intended magnetic strip pair to shear. This decrease can be obtained by continuously decreasing the length of the magnetic strip pairs, decreasing the exposed exterior areas of the strips, decreasing the overall volume of the magnetic strip pairs, and/or utilizing materials of varying magnetic capabilities.





FIG. 9

depicts an additional embodiment of the socket


200


in which the peripheral sleeve's lower end


202


and the sliding sleeves' offset lower ends


204


,


206


,


208


,


210


,


212


are gradually angled instead of offset, the angle being of sufficient magnitude to duplicate the upwards vertical restraint function of the shoulders described above.




In the embodiment of the socket


300


depicted in

FIG. 10

, the peripheral sleeve


302


is integrated with the retainer member. The sliding sleeves


304


,


306


,


308


,


310


,


312


,


314


have right angled lower ends


316


,


318


,


320


,


322


,


324


,


326


. The peripheral sleeve


302


presents a lower end


328


in position to prevent upwards vertical movement of the first sleeve lower end


316


. Starting with the first sleeve lower end


316


, all other sleeves


306


,


308


,


310


,


312


,


314


are restrained in the upwards vertical direction due to the vertical stacking of the lower ends


316


,


318


,


320


,


322


,


324


,


326


. The integration of the peripheral sleeve


302


with the retainer member eliminates the need for a magnetic strip pair


330


between the peripheral sleeve and the upper body interior wall


332


. As discussed above, this embodiment


300


also eliminates the magnetic strip pair


330


between the innermost sleeve


314


and the next largest sleeve


312


.




With respect to the above description then, it is to be realized that the optimum material and dimensional relationships for the parts of the adjustable socket


10


,


200


,


300


will include variations in size, materials, shape, and form, which will occur to those skilled in the art upon review of the present disclosure. For example the components can be constructed from various metals, including, steel, and can have multiple main body sizes so as to provide the appropriate cavity for sleeves to properly engage all typical English and metric fastener projection sizes. All equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
