PCT No. PCT/SE94/00129 Sec. 371 Date Dec. 21, 1994 Sec. 102(e) Date Dec. 21, 1994 PCT Filed Feb. 16, 1994 PCT Pub. No. WO94/22642 PCT Pub. Date Oct. 13, 1994.A nut wrench device, especially for loosening or tightening wheel nuts or similar (22), comprising an input axle (1) having operating means (3,23), an output axle (17) having actuating means (19-21) disposed at one of its ends, which actuating means (19-21) has a non-round peg (20) on which a nut socket or the like (21) is non-rotatably secured for wrenching the nut (22), a force transmission mechanism (7-16, 24, 26-29) which links the input axle (1) with the output axle (17), and anchoring means (5,25) to anchor the nut wrench device on a second wheel nut (6) spaced from the nut (22), whereby a force applied to the operating means is transmitted as a torque to the nut (22) which is to be wrenched. Novel in the invention is that the anchoring means (5,25) is disposed at one end of the input axle (1) and the operating means (3,23) is disposed at the second end (2 ), and the force transmitting mechanism (7-16, 24, 26-29) comprises a link member (9) which is connected to the input axle (1) via its first end and connected to the output axle (17) via its second end (2), the link member (9) being disposed substantially at right angles to both the input axle (1) and the output axle (17). |
