1. (WO2007012017) RATCHET DRIVER AND METHOD OF MAKING SAME
Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

What is claimed is:
1. A ratcheting driver configured to rotationally drive a work piece, the driver comprising:
a handle that includes a longitudinal axis and a hollow interior; a gear that includes gear teeth positioned thereon, wherein the gear is rotatably supported along the longitudinal axis in the hollow interior and wherein the gear is configured to rotationally drive a work piece;
a first pawl and a second pawl, each pivotally supported by the handle adjacent to the gear and being orbital about the axis upon and with rotation of the handle, wherein at least one of the pawls includes pawl teeth engageable with the gear teeth at a respective location on the gear teeth and wherein the pawl teeth are configured to transmit rotation from the handle to the work piece;
a spring configured to pivot the at least one pawl and to yieldingly urge the at least one pawl into rotational driving tooth engagement with the gear teeth; and
a force transmitting member configured to selectively pivot the at least one pawl out of rotational driving tooth engagement with the gear teeth, wherein the handle includes two spaced apart surfaces and wherein each of the pawls include two spaced-apart surfaces in respective sliding contact with the handle surfaces and with the handle surfaces being disposed to face the location for supporting the pawls in the teeth engagement of the pawls with the gear teeth at the location and further configured to urge the pawls to orbit about the axis and to thereby urge rotation of the gear about the axis.

2. The ratcheting driver of claim 1, wherein one of the handle surfaces and one of the pawl surfaces are of substantially the same shape and substantially fully overlie each other in two-dimensional contact during rotation of the gear.

3. The ratcheting driver of claim 1, wherein the spring is in sliding contact with the least one of pawl, wherein the spring is configured to move along the at least one pawl, and wherein the spring is further configured to urge the at least one pawl into driving tooth engagement with the gear.

4. The ratcheting driver of claim 1 , wherein the force transmitting member is rotatable on the handle and a stop interposed between the force transmitting member and the handle, thereby being configured to restrict rotation of the force transmitting member in one direction during assembly of the driver.

5. A method of arranging a ratcheting driver for rotationally driving a piece, the method comprising the steps of:
providing a handle that includes a hollow interior, a longitudinal axis, and two pockets supported by the handle;
placing two pivotal pawls in the pockets for orbital motion about the axis;
attaching a cap adjacent to the handle, wherein the cap is rotatable relative to the handle and about the axis and wherein the cap includes a portion extending toward the axis and between the pawls in final assembly and is configured to interfere with the pawls to restrict the rotation of the cap; and
placing a stop on the handle to substantially preclude rotation of the cap in one direction of rotation about the axis to assure positioning of the portion between the pawls.

6. The method of claim 5, further comprising the step of:
providing a spring adjacent one of the pawls for urging the pawl in a first direction; and
initially positioning the projection onto the one pawl for depressing the one pawl against the spring and then rotating and axially moving the cap relative to the handle for consequent positioning of the projection between the pawls in assembling the cap relative to the handle.

7. A driver, comprising:
a handle that includes a longitudinal axis and a hollow interior; a gear that includes gear teeth positioned thereon, wherein the gear is rotatably supported along the longitudinal axis in the hollow interior and wherein the gear is configured to rotationally drive a work piece; a pawl pivotally supported by the handle adjacent to the gear and being orbital about the axis upon and with rotation of the handle, wherein the pawl includes pawl teeth engageable with the gear teeth at a respective location on the gear teeth and wherein the pawl teeth are configured to transmit rotation from the handle to the work piece;
a first force transmitting member configured to pivot the pawl and to yieldingly urge the pawl into rotational driving tooth engagement with the gear teeth; and
a second force transmitting member configured to selectively pivot the pawl out of rotational driving tooth engagement with the gear teeth, wherein the handle includes two spaced apart surfaces and wherein the pawl includes two spaced-apart surfaces in respective sliding contact with the handle surfaces and with the handle surfaces being disposed to face the location for supporting the pawl in the teeth engagement of the pawl with the gear teeth at the location and further configured to urge the pawl to orbit about the axis and to thereby urge rotation of the gear about the axis.

A driver, comprising:
means for providing a handle that includes a hollow interior, a longitudinal axis, and two pockets supported by the handle;
means for placing two pivotal pawls in the pockets for orbital motion about the axis;
means for attaching a cap adjacent to the handle, wherein the cap is rotatable relative to the handle and about the axis and wherein the cap includes a portion extending toward the axis and between the pawls in final assembly and is configured to interfere with the pawls to restrict the rotation of the cap; and
means for placing a stop on the handle to substantially preclude rotation of the cap in one direction of rotation about the axis to assure positioning of the portion between the pawls.
