Abstract

A fastener holding device is designed for use with power tools. The device securely engages a fastener, such as a screw, and automatically disengages the fastener when the device is pushed against a work material. The device includes a driving bit assembly which has a socket on one end for holding a driving bit and has a polygonally shaped portion on the other end for mounting in a power drill. The device further includes a retaining member adapted to be placed on the driving bit assembly and a sleeve member adapted to be placed on the retaining member. The retaining member can be equipped with various engaging assemblies, such as brackets, bearings and pins, to securely engage the fastener. The position of the sleeve member in relation to the retaining member allows the fastener to be either engaged or disengaged with respect to the driving bit.

2. A fastener holding device according to claim 1, wherein the first end of the driving bit assembly is a socket configured to receive a driving bit.

3. A fastener holding device according to claim 2, wherein the socket has a recess for holding a hook which couples the driving bit to hold the driving bit within the socket.

4. A fastener holding device according to claim 1, wherein the first end of the driving bit assembly is a driving bit.

5. A fastener holding device according to claim 1, wherein a length of each one the plurality of recesses of the sleeve member determines when the engaging assembly disengages the fastener.

6. A fastener holding device according to claim 5, wherein as the length of the recess is longer, the fastener is disengaged earlier from the engaging assembly, and as the length of the recess is shorter, the fastener is disengaged later.

7. A fastener holding device according to claim 6, wherein the plurality of recesses includes at least one pair of oppositely disposed recesses, each having a first length.

8. A fastener holding device according to claim 6, wherein the plurality of recesses includes a first pair of substantially oppositely disposed recesses, each having a first length and a second pair of substantially oppositely disposed recesses, each having a second length.

9. A fastener holding device according to claim 1, wherein the retaining member is adjustably coupled to the driving bit assembly to accommodate fasteners having various head thicknesses.

10. A fastener holding device according to claim 9, further including a plug coupled to the retaining member, wherein the driving bit assembly has a first inclined collar and the plug has a second inclined collar, in which a position of the first inclined collar with respect to the second inclined collar determines the position of the retaining member with respect to the driving bit assembly.

11. A fastener holding device according to claim 1, wherein each one the plurality of brackets of the engaging assembly comprises a body and a leg, the leg being pivotally connected to a respective receptacle.

12. A fastener holding device according to claim 11, wherein the receptacle has a slot configured to receive the leg of the bracket.

13. A fastener holding device according to claim 1, wherein there are two receptacles positioned substantially opposite of each other to receive two brackets for holding the fastener.

14. A fastener holding device according to claim 1, further comprising a coil positioned in a surrounding relation to the retaining member and behind the sleeve member to bias the sleeve member to be in the first position.

15. A fastener holding device operable with a fastener, the fastener holding device comprising:

a driving bit assembly having a first end and a second end;

a retaining member adapted to be placed on the first end of and in surrounding relation to the driving bit assembly;

an engaging assembly coupled with the retaining member for maintaining an engaging position to hold the fastener within the retaining member, wherein the engaging assembly includes a plurality of brackets, wherein each one of the plurality of brackets includes a head portion, a body portion, and a leg portion; and

a sleeve member configured to be placed on and in surrounding relation to the retaining member, the sleeve member including a plurality of recesses, wherein each one of the plurality of recesses is configured to encase the head portion of the plurality of brackets, the sleeve member maintaining at least one of a first position and a second position relative to the retaining member, wherein the engaging assembly engages the fastener by being in the engaging position when the sleeve member is at the first position and disengages the fastener when the sleeve member is at the second position, wherein

the retaining member includes a plurality of receptacles and a plurality of slots, and wherein each one of the plurality of receptacles is sized to hold each one of the plurality of brackets, each one of the plurality of slots is sized to hold the leg portion of the plurality of brackets.

16. A fastener holding device according to claim 15, wherein the retaining member is adjustably coupled to the driving bit assembly to accommodate fasteners having various head thicknesses.

17. A fastener holding device according to claim 16, further including a plug coupled to the retaining member, wherein the driving bit assembly has a first inclined collar and the plug has a second inclined collar, in which a position of the first inclined collar with respect to the second inclined collar determines the position of the retaining member with respect to the driving bit assembly.

18. A fastener holding device according to claim 15, wherein there are two receptacles positioned substantially opposite of each other to receive two brackets for holding the fastener.

19. A fastener holding device according to claim 15, further comprising a coil positioned in a surrounding relation to the retaining member and behind the sleeve member to bias the sleeve member to be in the first position.

20. A fastener holding device operable with a fastener, the device comprising;

a driving bit assembly having a first end and a second end, wherein the second end is polygonally shaped and the first end having a first inclined member on an outer circumference of the driving bit assembly;

a retaining member configured to be placed on the first end of and in surrounding relation to the driving bit assembly, wherein the retaining member includes a plurality of receptacles and a plurality of slots;
