Example Embodiment

[0026] Now referring to these drawings, these drawings are only for the purpose of illustrating the preferred and different embodiments of the present invention and not for the purpose of limiting the same. Figure 1 to Figure 3 Shown in is a thin wrench 10 for installation with a fastener 160 that reduces upper operability and / or reduces rotational operability. Broadly speaking, the wrench 10 includes an elongated body 12 and a driving mechanism 80 incorporated into the body 12. The driving mechanism 80 may be supported on an irreversible, unidirectional roller clutch 90. Advantageously, the one-way roller clutch 90 provides a ratchet mechanism with minimal or substantially zero backlash.

[0027] Specific reference figure 1 as well as figure 2 In an embodiment, the body 12 of the wrench 10 may have a plurality of opposite ends, and these ends include a tool end 14 and a handle end 16 and include a head portion 18 and a handle portion 20. The drive mechanism 80 may be generall...

Abstract

A wrench for rotating a member comprises an elongate body having a head portion. The wrench may include a drive mechanism mounted to the head portion. The drive mechanism may comprise a drive gear and a clutch gear. The drive gear may include a drive element for engaging the member. The clutch gear may be operatively coupled to the drive gear and may be rotatably supported by a unidirectional roller clutch.

Description

technical field [0001] The present invention relates generally to hand tools of various types and, more particularly, to tools configured to allow operation of fasteners installed in areas of limited headroom or limited rotational space. Background technique [0002] Restricted access to fasteners is a common problem in a variety of industries. In the aerospace industry, the problem of restricted handling of fasteners is exacerbated by more stringent engineering requirements and less space constraints associated with aeronautical structures. Furthermore, relatively large quantities of fasteners are used in the aerospace industry compared to other industries. For example, hundreds or thousands of fasteners may be used on a single aircraft. A larger percentage of such fasteners can be installed in areas where access is restricted. [0003] For example, many aircraft include spars or stringers coupled to the skin piece in order to increase the rigidity of the skin piece. Su...
