Quick release integrated collet and chuck device

A quick release chuck device, comprising:

• a body member having means for mounting to a drive spindle of a drive tool;
• a frustoconical chamber defined in said body member and a collet device operably housed in said frustoconical chamber;
• longitudinally extending members disposed equally spaced around the circumference of said body member, said longitudinally extending members pivotally mounted relative to said body member at pivot points generally nearer a first end of said members, said longitudinally extending members having a second end opposite said first end wherein said second ends are movable radially outward from said body member as said body member is rotated in an operational mode of said chuck device, said second ends comprising a weighted portion;
• said first ends of said longitudinal members engaging said collet device and forcing said collet device longitudinally into said frustoconical chamber when said second ends move radially outward thereby causing said collet device to grip a tool shank carried therein;
• spring members operably disposed between said longitudinally extending members and said body member so as to impart an initial radially outward bias to said second ends of said longitudinally extending members;
• and
• a spring biased sleeve member disposed about said body member and said longitudinally extending members, said sleeve member manually movable relative to said body member so as to contact and move said longitudinally extending members radially inward against the force of said spring members to allow a tool shank to be inserted into said collet device.

• spring members operably disposed between said longitudinally extending members and said body member so as to impart an initial radially outward bias to said second ends of said longitudinally extending members;
• and
• a sleeve member disposed over said longitudinally extending members, said sleeve member having access openings defined therein to provide access for an operator to manually squeeze said longitudinally extending members radially inward to insert a tool shank into said device, said sleeve member further comprising a covering of resilient material at least covering said access openings.

A quick release chuck device, comprising:

• a body member;
• a frustoconical chamber defined in said body member;
• a collet device operably housed in said frustoconical chamber;
• at least two longitudinally extending members disposed equally spaced around the circumference of said body member, said longitudinally extending members pivotally mounted relative to said body member at pivot points generally nearer a first end of said members, said longitudinally extending members having a second end opposite said first end wherein said second ends are movable radially outward from said body member as said body member is rotated in an operational mode of said chuck device;
• said first ends of said longitudinal members engaging said collet device and forcing said collet device longitudinally into said frustoconical chamber when said second ends move radially outward thereby causing said collet device to grip a tool shank carried therein;
• and
• a sleeve member longitudinally movable relative to said body member, said sleeve member comprising a surface for contacting said longitudinally extending members as said sleeve member is manually moved relative to said body member thereby causing said longitudinally extending members to move radially towards said body member so that a tool shank can be inserted into said collet device.
