Abstract
The present invention is directed to a switching device with a rotatably mounted operating element (10) and an eccentric element (12) for translating a rotational displacement (14) of the operating element (10) into a translatory displacement (16) of a switching element (18), in particular a selector shaft of a hand-held power tool. It is provided that a shape of the eccentric element (12) differs significantly from that of a rod.
Claims8
A switching device with a rotatably mounted operating element (10) and an eccentric element (12) for translating a rotational displacement (14) of the operating element (10) into a translatory displacement (16) of a switching element (18), wherein the switching element is in the form of a selector shaft of a hand-held power tool, wherein a shape of the eccentric element (12) differs significantly from that of a rod as well as a circular shape, wherein the eccentric element (12) has a guide surface (24, 26) provided to convert the rotational displacement (14) using a contact point (28, 30) that travels on the guide surface (24, 26) during the rotational displacement (14), wherein the guide surface (24) is substantially parabolic in shape, and wherein a vertex of the parabolic-shaped guide surface (24) points outwardly in a radial direction.
A hand-held power tool comprising a switching device, wherein the switching device comprises a rotatably mounted operating element (10) and an eccentric element (12) for translating a rotational displacement (14) of the operating element (10) into a translatory displacement (16) of a switching element (18) in the form of a selector shaft of a hand-held power tool, and wherein a shape of the eccentric element (12) differs significantly from that of a rod as well as from a circular shape, wherein the eccentric element (12) has a guide surface (24, 26) provided to convert the rotational displacement (14) using a contact point (28, 30) that travels on the guide surface (24, 26) during the rotational displacement (14), wherein the guide surface (24) is substantially parabolic in shape, and wherein a vertex of the parabolic-shaped guide surface (24) points outwardly in a radial direction.
An eccentric element (12) for translating a rotational displacement (14) of an operating element (10) of a hand-held power tool into a translatory displacement (16) of a switching element (18) of the hand-held power tool, wherein a shape of the eccentric element (12) differs significantly from that of a rod as well as a circular shape, wherein the eccentric element (12) has a guide surface (24, 26) provided to convert the rotational displacement (814) using a contact point (28, 30) that travels on the guide surface (24, 26) during the rotational displacement (814), wherein the guide surface (24) is substantially parabolic in shape, and wherein a vertex of the parabolic-shaped guide surface (24) points outwardly in a radial direction.
