Three jaw adjustable socket

Abstract

A ⅜ drive adjustable socket apparatus comprised of a three jaw socket members which ride triangularly and radially within an upper cylindrical tapered housing. The jaw members are abutted inward at 15 degrees to the jaw housing radial walls of the same angular taper. Each jaw member has an inner 120 degrees V-notch which becomes a hexagonal configuration when they are trilaterally spaced apart to accept standard hexagonal configured nuts and bolt type fasteners. The adjustable socket apparatus has a ⅜ inch driver end which has a two slotted windows to allow the use of thumb and index finger to rotate the inner serrated wheel that is exposed through both opposite window slots on the bottom portion of the adjustable socket embodiment. The lower driver end of the adjustable socket has a ⅜ square cavity to accept male universal ratcheting driver. The adjustable socket's driver embodiment also has an internal serrated fixed wheel and a right hand threaded central actuator unit which is solidly affixed onto the vertical shaft. When the serrated wheel is manually rotated, it influences the three jaws to either move upwards or downward depending on the axial rotation of the main vertical thread. The three jaws maneuvering is accomplished by a smaller, upper diameter actuator ring horizontally seated at the lower limb of each jaw member to influence its movement in either an upward or downward and tapered motion. The main vertical thread screw is attached to the vertical adjusting wheel which is secured by the horizontal retention snap ring located beneath an internal groove just above the said serrated wheel. As the user rotates the exposed serrated wheel and its vertical threaded vertical internal screw, it will activate the smaller diameter upper horizontal wheel upwards or downwards as the main vertical thread and serrated gear is being manually rotated on its Z axis. This actuates the threaded adjusting horizontal ring which is housed within the three jaw members' lower slotted or pocket features. The upward and or downward, X coordinate rotation will influence the jaw members to move in either an upward or downward motion at a 15 degree inward angle and ride within the tapered cylindrical walls of the upper jaw housing at the same 15 degree angle. Either a clockwise or counterclockwise rotation causes the main central right hand threaded actuator wheel, when rotated, to move the jaws upward and/or downward because of the influence of the main vertical threaded screw.

Description

BACKGROUND OF THE INVENTION

This utility patent application is for an adjustable socket apparatus having three jaws trilaterally spaced 120 degrees, each jaw having a 120 degrees interior notch feature which becomes a hexagonal configuration to accept hexagon type nuts and bolt fasteners. The adjustable socket apparatus has six main components as follows: three jaw members within the upper jaw housing, a lower driver housing, and a main actuator serrated wheel with affixed main vertical threaded right hand screw which is permanently attached onto the main adjusting serrated thumb wheel. The serrated wheel is retained internally by a standard snap retention C-ring. A smaller actuator wheel is threaded onto the main vertical screw, the thread of which activates the smaller horizontal threaded ring to activate the three jaw members at their lower notches. The manual rotational activation influences the three jaw members to move on an inward/upward or outward/downward path at a 15 degrees angle. The upper and lower main components are threaded and secured as a unit by two fastener dowel pins. Each jaw member has an exterior 30 degrees dovetail projection on the jaw outer surface. This dovetail feature rides and interlocks within the corresponding female dovetail recessed slot feature for additional jaw stability and torque strength for the jaw members.

Nos. 5,819,607, 6,073,522 and 7,261,021 B1, there is disclosed a socket which is manually adjustable to enable the socket to grip nuts or bolts with hexagonal configured heads of different sizes. Two opposing jaw members are provided which are adjustably spaced apart to grip a hexagonal bolt head of a selected size. Although the socket allows a user to make the necessary adjustments, it includes numerous components that may add to the cost of manufacturing this adjustable socket tool.

SUMMARY OF THE INVENTION

1. The object of this invention is to provide an adjustable socket apparatus having a sizeable range from ⅜ to ⅝ inch, and 10 mm to 17 mm to either tighten or loosen hexagonal configured nuts and bolt type fasteners. This new preferred adjustable socket apparatus attaches onto a standard universal ⅜ male driver for tightening and/or loosening standard hex shaped fasteners. This adjustable socket apparatus has a range of twelve hexagonal size openings that range as follows: ⅜ inch, 10 mm, 11 mm, 7/16 inch, 12 mm, ½ inch, 13 mm, 14 mm, 9/16 inch, 15 mm, 16 mm, ⅝ inch and 17 mm. The adjustable socket's lower driver component includes a ⅜ inch square driver cavity to accept standard universal male ratchet drivers. The lower diameter of the lower embodiment has a knurled feature to allow the user to insert and manually align the adjustable socket onto a fastener to be worked. This adjustable socket features three jaws that have a 120 degree internal V-cavity. The jaws are triangularly positioned to each other at 120 degrees, which becomes a hexagonal configuration. The adjustable socket has a lower serrated adjusting wheel that has peripheral serrations exposed through two windows opposite each other. It can be rotated in either a clockwise or counterclockwise rotation to either activate the jaws to move in the upward or downward adjustment at a 15 degree inward or outward taper to close the jaws to a smaller hex opening or open the jaws in the downward path to a larger hex opening. This is accomplished by an internal affixed vertical right hand thread that has an attached horizontal threaded ring disk that seats within the lower slotted pocket of the jaw members. The manual axial rotation of the main serrated wheel that is peripherally threaded, and has a vertical main male thread which influences the horizontal threaded disk to induce the jaws to either move in a tapered and upwards or downwards path at a 15 degrees taper.

Claims

1. A three jaw adjustable socket with a number of adjustable socket size openings to accommodate different size hexagonal fasteners, a fixed and a lower drive member with an interior serrated wheel with exterior teeth that are exposed through two opposite slotted windows on the lower adjustable socket driver embodiment. The exposed teeth through two slotted windows 180 degrees apart are provided at the lower driver embodiment of the adjustable socket apparatus are for thumb and index finger axial rotation. This manual rotation activates the three jaw members that taper together by axial rotation to smaller hex opening adjustments, as the serrated wheel is being manually rotated in a counterclockwise rotation. This downward rotation movement expands the jaw members to larger hexagonal openings. The upper jaw housing and the lower driver housing is an exterior unit. The upper jaws cylindrical housing retains the three trilateral jaw members that that are positioned 120 degree triangularly and move axially and on a 10 degree taper upwards to a smaller hexagonal size as the three jaws come together. When the user rotates the serrated gear in the opposite rotation of the serrated exposed wheel, the three jaw members' axial movement is expanded downward at 15 degree to a larger hex opening on the Z axis plane and is influenced by a horizontal cylindrical threaded disc that is threaded onto a vertical main threaded helix screw. The threaded disc is nestled within the lower jaws pocket, and the threaded disc driver unit is manually rotatable to a clockwise or counterclockwise rotation depending on the desired jaw openings.

2. Each jaw member has an exterior 30 degree included dovetail projection on the jaw outer surface. This dovetail feature rides and interlocks within the corresponding female dovetail recessed slot feature on the upper cylindrical jaw housing for additional jaw stability and torque strength for each of the jaw member. The main actuator serrated wheel with affixed main vertical threaded right hand screw is permanently attached onto the main adjusting serrated thumb wheel. It is retained internally by a standard snap retention C-ring. A smaller horizontal actuator wheel ring is threaded onto the main vertical screw which activates the three jaw members at their lower notch. The manual rotational activation influences the three jaw members to move inward or downward at a 15 degree angle. The upper and lower main components are threaded and secured by two fastener dowel pins. Each jaw member has an exterior 30 degrees dovetail projection on the jaw outer surface. This dovetail feature rides and interlocks within the corresponding female dovetail recessed slot feature on the upper cylindrical jaw housing for additional jaw stability and torque strength to each of the jaw members.
