Patent Application
20120272781
This application claims the benefit and priority of German Patent Application No. 10 2011 018 988.2, filed Apr. 28, 2011. The entire disclosure of the above application is incorporated herein by reference.
The disclosure relates to an actuating device and, more particularly, to an actuating device with a handle that is secured in different positions with respect to the shaft.
An actuating device is known according to DE 196 45 778 A1. This actuating device, which is implemented as a clamping device, has an actuating element (clamping arm), that is connected in a rotationally fixed manner to a shaft that is rotatable in a housing. The actuating element is pivotable using a hand lever connected to the shaft The hand lever is formed from an attachment element connected to the shaft. An elongated handle element is fastened on it. In this solution, the handle element is fixedly connected to the attachment element. The attachment element itself can be fastened in four different positions on the shaft since the shaft has a square cross section perpendicular to its main axial direction.
The disclosure improves the actuating element of the above mentioned type. In particular, the flexibility of the attachment of the hand lever to the actuating device is improved.
An actuating device comprises an actuating element, which is connected in a rotationally-fixed manner to a shaft mounted so it is rotatable in a housing. The actuating element is pivotable using a hand lever connected to the shaft. The hand lever is formed from an attachment element connected to the shaft and an elongated handle element fastened to it. The handle element is fastenable at different positions on a front side of the attachment element. The front side is oriented perpendicularly to the main axial direction of the shaft.
Thus, the handle element is fastenable at different positions to the front side of the attachment element oriented perpendicularly to the main axial direction of the shaft.
According to the disclosure, the fastening of the handle element no longer occurs on a peripheral surface of the attachment element, but rather on its (shaft-free) front side. Depending on the diameter of the attachment element, its outer peripheral surface (cylinder lateral surface) is relatively small. The number of possible fastening points is limited, for example, to four places, as in the solution according to DE 60 2004 010 217 T2. In contrast, even with a small diameter of the attachment element, a relatively large number of fastening points for the handle element can be provided on the front side of the attachment element. The attachment of the hand lever to the actuating device can be more precisely adapted to the actual spatial conditions at the usage location.
Further areas of applicability will become apparent from the description provided herein. The description and specific examples in this summary are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.
The actuating device according to the disclosure, including the advantageous refinements according to the claims, is explained in greater detail on the basis of the illustration in the drawing of various exemplary embodiments.
The actuating or clamping devices shown in
With respect to the disclosure to be explained hereafter, a square cross section, which is also known per se, is particularly preferably provided, because, for example, a hexagonal cross section typically causes higher manufacturing costs.
The actuating element 3 is pivotable using a hand lever 4 connected to the shaft 2. The hand lever 4 is formed from an attachment element 5. The attachment element 5 is connected to the shaft 2 and is preferably arranged on the free end of the shaft 2. An elongated handle element 6 is fastened to the attachment element 5.
Although it is not shown separately in
The shaft 2 can include a hollow shaft and an inner shaft. The actuating element 3 is connected in a rotationally-fixed manner to the hollow shaft. The attachment element 5 is connected in a rotationally-fixed manner to the inner shaft.
In all embodiments of the actuating device of the disclosure, the handle element 6 is fastenable at different positions on a front side 7 of the attachment member. The front side 7 of the attachment element 6 is oriented to be at least substantially perpendicular to the main axial direction of the shaft 2. As explained at the beginning, particular advantages result from this measure with respect to a flexible arrangement or assignment of the handle element 6 to the actuating device. As shown in
The handle element 6 is fastened to the attachment element 5 by two fastening connections 8. The fastening connections 8 are positioned at a distance from one another. The fastening connections 8 are each formed from one attachment-element-side and one handle-element-side fastening element 9, 10. The fastening elements 9, 10 include, for example, corresponding threaded holes and screws or threaded rods and nuts. The fastening connection 8 is preferably a screw connection. Furthermore, two through holes for two corresponding fastening elements 9, 10 are provided on the handle element 6.
Multiple attachment-element-side fastening elements 9, for example, threaded holes, are arranged on the attachment element 5. Not all attachment-element-side fastening elements 9 can be recognized in
In both the embodiments according to
In the solution according to
In
Finally, it is to be noted in this context that
The description of the disclosure is merely exemplary in nature and thus, variations that do not depart from the gist of the disclosure are intended to be within the scope of the disclosure. Such variations are not to be regarded as a departure from the spirit and scope of the disclosure.
