Ratchet wrench
A ratchet wrench includes a fastener drive member and a rigid, one-piece frame having a handle portion extending along a longitudinal frame axis between a head portion and a finger loop. The fastener drive member has a pair of drive openings centered on the drive axis and facing in opposite directions, with each of the drive openings defined by one or more drive surfaces. One of the drive openings is sized to receive a fastener or driver bit of a first size and the other opening is sized to receive a fastener or driver bit of a second size greater than the first size. The finger loop has a finger receiving opening sized to receive and encircle a finger of a user. The fastener drive member is mounted in the head portion to rotate about a drive axis, and a ratchet mechanism is mounted in the head portion in operable connection to the fastener drive member to selectively transfer torque from the frame to the fastener drive member in either a clockwise or counterclockwise direction about the drive axis.
1. A ratchet wrench adapted to be operated in confined spaces the ratchet wrench comprising:
a fastener drive member having a pair of drive openings centered on a drive axis and facing in opposite directions, each of the drive openings defined by one or more drive surfaces, one of the drive openings sized to receive a fastener or driver bit of a first size and the other opening sized to receive a fastener or driver bit of a second size greater than the first size;
a reversible ratchet mechanism;
a rigid, one-piece frame having a handle portion extending along a longitudinal frame axis between a head portion and a finger loop, the finger loop having a finger receiving opening sized to receive and encircle a finger of a user, the fastener drive member mounted in the head portion to rotate about the drive axis, and the ratchet mechanism mounted in the head portion in operable connection to the fastener drive member to selectively transfer torque from the frame to the fastener drive member in either a clockwise or counterclockwise direction about the drive axis, wherein the handle portion forms partial flanges on either side of the finger loop defining a wider neck portion extending from the finger loop towards a middle portion of the frame;
a magnet located in the fastener drive member between the openings; and a magnet housing, the magnet mounted in the magnet housing, and the magnet housing having an interference fit with the fastener drive member.
2. The ratchet wrench of claim 1 wherein one of the drive openings of the fastener drive member is configured to engage a ¼ inch hexagonal drive portion on a fastener or drive bit, and the other drive opening of the fastener drive member is configured to engage a 5/16 inch hexagonal drive portion on a fastener or drive bit.
3. The ratchet wrench of claim 1 wherein the magnet has a through bore centered on the drive axis.
4. The ratchet wrench of claim 1 wherein the magnet has a cylindrical outer surface centered on the drive axis.
5. The ratchet wrench of claim 1 wherein the fastener drive member comprises a thumb wheel having a diameter transverse to the drive axis that is greater than a maximum width of the head portion transverse to the frame and drive axes.
6. The ratchet wrench of claim 1 wherein the head portion has a maximum width transverse to the frame and drive axes, the finger receiving opening has a maximum width transverse to the frame and drive axes that is greater than the maximum width of the head, the maximum width of the head portion is no greater than ⅞ inch, and the maximum width of the finger receiving opening is no less than ⅞ inch.
7. The ratchet wrench of claim 1 wherein at least part of the handle portion has a width transverse to the frame and drive axes that is less than the maximum width of the head portion.
8. The ratchet wrench of claim 1 wherein the finger receiving opening has a circular shape.
9. The ratchet wrench of claim 1 wherein the finger loop has an arcuate outer surface that partially surrounds the finger receiving opening.
