Abstract
An eye screw driving device for insertion and removal of eye screws having a generally cylindrical elongate body with a generally eye-screw-shaped recess formed in one end thereof, having a cover slidable into and out of a covering relation with the recess to retain the eye screw therein, the recess having an upstanding post positioned therein to allow the recess to accept a number of different eye screws formed of the same diameter bolt stock, yet with different head sizes, the device being fitted within a mounting post allowing the device to he mounted in a rotary drive power tool.
Claims12
A device for use in driving insertion and removal of a plurality of differently-sized eye screws and hooks of the type having an eyelet-shaped head portion and a shank extending therefrom for rotational penetration of a supporting member, wherein said eye screws and hooks have respective head portions and respective shanks of a common cross-sectional dimension, but differ in the overall size of their respective head portions, said driving device comprising:
- a body defining a rotational driving axis about which said body may be rotatably driven;
- a recess in said body, said recess having a main area sized and configured in conformity to the head portion of the eye screw or hook of said plurality of eye screws and hooks which has the largest-sized head portion and a channel portion which opens to one end of said body and is sized and configured in conformity to the common cross-sectional dimension of the respective shanks of said plurality of eye screws and hooks, said recess being capable of receiving interchangeably any selected one of said plurality of eye screws and hooks with the respective head portion thereof disposed within the main area of the recess and the respective shank disposed within the channel portion of the recess to extend outwardly from said one end of said body in alignment with said rotational axis;
- a cover device mounted on said body for selective sliding movement between an extended position disposed in covering relation to said recess for retaining the head portion of the eye screw or hook therein and a retracted position out of covering relation to said recess for selective insertion and removal of eye screws and hooks into and from said recess;
- and
- an upstanding post formed in said main area of said recess for insertion through the eyelet portion of any eye screw or hook received therein, said post being of a size and configuration to occupy no greater than the area within the eyelet portion of the eye screw or hook of said plurality of eye screws and hooks which has the smallest-sized head portion and to occupy less than the entirety of the area within the eyelet portion of each other eye screw or hook of said plurality of eye screws and hooks, said post being disposed at an offset within the main area of said recess to be spaced most closely to said channel portion, the spacing of said post to said channel portion corresponding to said common cross-sectional dimension of the head portions of said plurality of eye screws and hooks to prevent shifting movement within the main area of the recess by any eye screw or hook received therein.
A device for use in driving insertion and removal of eye screws and hooks of the type having an eyelet-shaped head portion and a shank extending therefrom for rotational penetration of a supporting member, said driving device comprising:
- a body defining a rotational driving axis about which said body may be rotatably driven;
- a recess in said body, said recess having a main area for receiving the head portion of an eye screw or hook and a channel portion which opens to one end of said body for positioning the shank to extend outwardly from said one end of said body in alignment with said rotational axis;
- a cover device mounted on said body for selective sliding movement between an extended position disposed in covering relation to said recess for retaining the head portion of the eye screw or hook therein and a retracted position out of covering relation to said recess for selective insertion and removal of eye screws and hooks into and from said recess;
- a series of substantially linearly aligned openings formed in said body within said main area of said recess;
- and
- a post configured for selective insertion into and removal from any of said openings for removably mounting said post in an upstanding manner within said recess, said post being configured for insertion through the eyelet portion of the eye screw.
A device for use in driving insertion and removal of eye screws and hooks of the type having an eyelet-shaped head portion and a shank extending therefrom for rotational penetration of a supporting member, said driving device comprising:
- a body defining a rotational driving axis about which said body may be rotatably driven;
- a recess in said body, said recess having a main area for receiving the head portion of an eye screw or hook and a channel portion which opens to one end of said body for positioning the shank to extend outwardly from said one end of said body in alignment with said rotational axis;
- a cover device mounted on said body for selective sliding movement between an extended position disposed in covering relation to said recess for retaining the head portion of the eye screw or hook therein and a retracted position out of covering relation to said recess for selective insertion and removal of eye screws and hooks into and from said recess;
- a movable post mounted in said recess for insertion through the eyelet portion of the eye screw or hook.
