Definitions
- the invention relates to a tensioning device according to the preamble of independent claim 1.
- a clamping device of the type mentioned is known from DE 196 45 778 Cl. This consists of a provided with a linearly movable actuator and a pivot shaft for a clamping arm toggle mechanism associated with the means for unlocking an over-center position, wherein
- CONFIRMATION COPY these are formed from a control element arranged on the actuator (called abutment surface there) and from a rocker which can be brought into adjustment contact with the adjusting element (there called an adjusting pin).
- the invention has for its object to improve clamping devices of the type mentioned. In particular, a simpler and less expensive to produce and more reliable solution to be created.
- the actuating element oriented away from the pivot shaft is designed as an actuating extension and the actuator is arranged between the pivot shaft and the rocker.
- the means for unlocking the located in the over-center position actuating mechanism of the clamping device are thus formed from a linearly movable actuator from the actuator arranged as Stellfortsatz actuating element and further from a with the actuating extension in adjustable contact and actuated by a flank side of the tensioning device rocker so in the Head of the device in the travel of the actuating extension projects, which will be explained in more detail.
- the rocker is in the form of a small one-armed, entrained by Stellfortsatz to Mattertot Vietnamese lever and accordingly arranged at the appropriate location of the head piece, with its pivot axis and the pivotally connected to it pivot shaft of the clamping arm particularly preferably extends from flank side to flank side of the head piece and thus accessible from the outside.
- the swingarm remains on reaching the fürtot Vietnameseposition in adjusting contact with the Stellfortsatz so that, if necessary, by actuation of the rocker, the actuator can be solved via it seated Verstellfortsatz from its over-center position.
- the arrangement of the rocker at Kochtot Vietnamesesent Scheme- and edge side point in the head causes the lateral access to the pivot shaft outside the pivoting range of the clamping arm and thus it does not automatically to threats an accessing hand in itself due to about in the device still existing operating pressure Low tension can come.
- the present invention provides the advantage of lateral assignment possibility basically arbitrarilyproofder handle for the provision of the rocker, which also, what will also be explained in more detail can change to the effect that it is possible with her, if necessary, the Actuator also press by hand in Automattothuis position to be able to which embodiment is preferred.
- the actuating extension to be attached to the actuator is, as explained, arranged oriented against the back of the clamping device, d. H. , to the tension arm or schwenkwellenabgewandten narrow side of the head piece out, which also results in the arrangement of the rocker in accordance with the rear portion of the head piece, in the quasi control and connection side usually in such tensioning devices and their sensor technology is housed. If the actuator in the sense of DE 202 09 237 Ul or DE 202 05 994 Ul two-piece and thus variable in length, so in this case the actuating extension is arranged on the knee lever mechanism near part of the actuator.
- Figure 1 the clamping device in side view and in
- FIG. 2 shows the clamping device according to FIG. 1 with the preferred embodiment of the rocker
- FIG. 3 shows the clamping device according to FIG. 2 in an intermediate position
- FIG. 4 shows the clamping device according to FIG. 2 in the open position
- Figure 5 enlarges the rocker in side view
- the clamping device shown greatly simplified in Figures 1 to 4 consists with reference to these figures in a known manner from a housed in a head piece 20, provided with a linear from a (especially pneumatic) drive 22 (for example, a reciprocating piston) of movable actuator 1 Knee lever mechanism 2, which is associated with means for unlocking an over-center division.
- a (especially pneumatic) drive 22 for example, a reciprocating piston
- the adjusting mechanism 2 include, as usual, nor an intermediate member 25 for connection between the actuator 1 and a shaft lever 24 a pivot shaft 23 with the clamping arm 21st
- the actuating element 3 is designed to be remote from the pivoting shaft and designed as a positioning extension and the actuator 1 is arranged between the pivoting shaft 23 and the rocker 4, ie the rocker 4 is designed to be actuatable from one flank side of the tensioning device.
- the actuating element 3 or the actuating extension is preferably arranged on the knee lever-mechanical end of the actuator 1, as a pin oriented transversely to this and against the back 5 of the head piece 20, d. H. , there is the rocker 4, which is also arranged outside the pivoting sector of the associated with the adjusting mechanism 2 clamping arm 21 on the head piece 20.
- the rocker 4 only has a nose protruding into the actuating path of the actuating extension 3, which, when turned clockwise, the actuating element 3 or the actuating extension and thus the actuator 1 from the over-center position pushes something down, after which the actuator 1 can be further moved down until the clamping arm 21 reaches its open position (see Figure 4).
- the stop 8 shown with ensures that the nose of the rocker 4 in dashed lines indicated position continues to protrude into the travel of the actuating element 3 and 4 Stellfortsatzes and can be taken back at stroke of the actuator 1 again.
- this can be associated with a suitable spring element 9, which is indicated only with a direction of effect arrow, as in Figure 2.
- the rocker 4 is in an advantageous development provided at its free end 6 with a receiving groove 7 for the engagement of the actuating element 3 and the Stellfortsatzes, as enlarged in Figure 5 illustrates.
- a stop 8 and possibly also a small spring element 9 are expediently provided.
- the rocker 4 at its free end 6 two well rounded noses overlapping one another, between which the actuator 3 and the actuating extension can intervene and thereby both the rocker 4 entrains both in upward and downward movement of the actuator 1.
- the bearing part 12 of the rocker 4 with its bearing pin 10 is provided with a through hole 13, so that advantageous handling elements, such as socket wrenches or the like, from both flank sides of the jig and in a suitable manner against rotation in the through hole can be used if necessary.
- the actuating element 3 or the actuating extension is arranged on the part 1.1 of the actuator 1 close to the toggle mechanism or associated therewith.
