Rotary tool holder
First Claim
1. A tool holder for releasably coupling a bit with a non-circular outer connector surface to a rotary driver, comprising:
- a socket having a forward end and an opening extending rearwardly from said forward end, said opening having a non-circular cross section adapted to receive the outer connector surface of the bit to couple the bit for rotation with the socket; and
a retaining mechanism coupled to said socket and operable in a retaining mode and a released mode, said retaining mechanism having a rubber o-ring, said retaining mechanism adapted to permit disposal of the bit into an operative position within the opening and to prevent axial displacement of the bit out of its operative position when the retaining mechanism is in its retaining mode, said rubber o-ring biasing said retaining mechanism into its retaining mode, said retaining mechanism further adapted to permit axial displacement of the bit out of its operative position when the retaining mechanism is in its released mode, said retaining mechanism including a sleeve and a spring, said sleeve coupled to said socket for displacement toward said forward end of said socket from a locked position to an unlocked position to move said retaining mechanism from said retaining mode to said released mode, said spring biasing said sleeve into its locked position.

Abstract
A tool holder for releasably coupling a bit with a non-circular outer connector surface to a rotary driver. The tool holder includes a socket and a retaining mechanism coupled to the socket and operable in a retaining mode and a released mode. The socket includes a forward end with an opening extending rearwardly from the forward end. The opening also includes a non-circular cross-section adapted to receive the outer connector surface of the bit to couple the bit for rotation with the socket. The retaining mechanism is adapted to permit disposable of the bit into an operative position within the opening and to prevent axial movement of the bit out of its operative position when the retaining mechanism is in its retaining mode. The retaining mechanism is further adapted to permit axial displacement of the bit out of its operative position when the retaining mechanism is in its released mode. The retaining mechanism includes a sleeve coupled to the socket for displacement toward the forward end of the socket from a locked position to an unlocked position thereby moving the retaining mechanism from its retaining mode into its released mode. The retaining mechanism also includes a spring or alternately a rubber o-ring biasing the sleeve into its locked position.

6. A tool holder for releasably coupling a bit with a non-circular outer connector surface to a rotary driver, comprising:
-
a socket having a forward end and an opening extending rearwardly from said forward end, said opening having a non-circular cross section adapted to receive the outer connector surface of the bit to couple the bit for rotation with the socket;
a sleeve displaceable axially along said socket between a locked position and an unlocked position;
a spring biasing said sleeve toward its locked position;
a detent mechanism having a rubber o-ring biasing said detent mechanism into said opening and adapted to engage the bit and prevent axial removal of the bit from the opening when said detent mechanism is in an engaged position;
said detent mechanism being movable between its engaged position to first and second disengaged positions, said sleeve preventing movement of said detent mechanism from its engaged position into its second disengaged position while permitting movement of said detent mechanism from its engaged position into its first disengaged position when said sleeve is in its locked position, said sleeve permitting movement of said detent mechanism from its engaged position to its second disengaged position when said sleeve is in its unlocked position. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A rotatable tool comprising:
-
a bit having a non-circular outer connector surface; and
a tool holder having a socket and a retaining mechanism, said socket having a forward end and an opening extending rearwardly from said forward end, said opening having a non-circular cross section, said bit being disposable in an operative position within said socket wherein said opening receives said connector surface to couple said bit for rotation with said tool socket, said retaining mechanism including;
a detent mechanism movable between an engaged position and first and second disengaged positions, said bit displacing said detent mechanism into its first disengaged position during insertion of the bit into its operative position, said detent mechanism extending into said opening to engage the bit and prevent axial removal of the bit from the opening when said detent mechanism is in its engaged position and the bit is in its operative position, said bit displacing said detent mechanism into its second disengaged position during removal of the bit from its operative position, said detent mechanism including a rubber o-ring biasing said detent mechanism into its engaged position, a sleeve displaceable axially along said socket between a locked position and an unlocked position, said sleeve preventing movement of said detent mechanism from its engaged position into its second disengaged position while permitting movement of said detent mechanism from its engaged position into its first disengaged position when said sleeve is in said locked position, said sleeve permitting movement of said detent mechanism from its engaged position to its second disengaged position when said sleeve is in said unlocked position, and a spring normally biasing said sleeve into said locked position. - View Dependent Claims (14, 15, 16)
