In addition, a monitoring module 60 for limiting the path of movement of the support 42 additionally provided, the task of the monitoring module 60 it is then to limit the forward and reverse path when the conveyor body 433 from the forward and reverse drive means 431 moving forward or backward, and being one on the foundation plate 1 mounted bracket 61 , and two limit switches 62 which is at a head end of the bracket 61 are arranged, and in contact with the conveyor body 433 or the support 42 then come when the conveyor body 433 forward or backward is moved down.

If the two limit switches 62 depending on the forward or backward movement of the conveyor body 433 come into contact, then send it to the control unit 2c a touch signal, and thus the receiving this controller 2c leads to switching off the operation of the forward and reverse drive means 431 , Accordingly, the limit switches 62 the forward or Rückwärtsbewegungsweg of the conveyor body 433 limit.

Of course, it is here in this inventive description that the structure of the Drehwinke monitoring module 50 and the monitoring module 60 for limiting the movement path according to the respective task can be changed and interpreted in various ways.

Further, as in 7 it can be seen is a housing 3 provided that it is the foundation plate 1 includes, with the foot plate 23 is exposed outside, and that to the top of the foot plate 23 a separate cover (not shown) for the foot plate 23 is connected.

following an operation of the invention described above, amplitude-controlled vibration device described in more detail.

One on the foot plate 23 Stagnant user can by means of the tower support 2 provided operating buttons 2 B the start / stop, or an amplitude range, etc. control.

Accordingly, if the foot plate 23 The left and right are thereby selectively moved up and down, then the other components are operated so that the up and down movement drive motor 11 of the up and down drive means 10 by the operation of the control unit 2c is operated, and the over the belt B with the drive pulley 111 connected drive pulley 311 is turned so that the actuating rod 31 also performs a linear movement.

After that, the opposed cams 32 each at both ends of the operating rod 31 camshafts 321 rotated, and connected to this interconnection body 33 Also performs an elliptical motion up and down, as well as on the interconnection body 33 connected levers 41 an up and down movement.

In doing so, starting from as the point of action for the lever 41 serving supports 42 , does that with the lever 41 coupled support means 232 for raising and lowering the with the support means 232 connected foot plate 23 , so that this can perform an optional left and right up and down movement (linkage movement).

That is, as shown in FIGS. 3a and 3b 3 it can be seen that moves a lever 41 starting from the front support 42 the supportive means 232 down, and thereby the other lever 41 starting from the support 42 the supportive means 232 upwards.

Besides, if the amplitudes of the foot plate 23 by the amplitude changing means 40 is changed, then the other components, like out 4 to 6 can be seen operated in that the forward and reverse drive motor 431a of the forward and reverse drive means 431 through the control unit 2c is pressed, and thus with the engine 431a connected rotary shaft 432 is rotated, so that the conveyor body 433 Therefore, it is moved backwards because of the thread 432a and the mating thread 433a paired together.

Thereafter, the conveyor body 433 through the help unit 434 guided and moved, ie the conveying part 434a of the conveyor body 433 along the guide bar 434b moves backwards. In doing so, if the conveyor part 434a through the limit switches 62 of the monitoring module 60 reached to limit the path of movement predetermined path, then it can not be moved backwards, the limit switches 62 the control unit 2c a touch signal of the support 2c or the conveyor body 433 send, so that the forward and reverse drive motor 431a through the control of the control unit 2c could be switched off.

For that with the conveyor body 433 coupled and acting as a point of support 42 , its starting point is along the lever 41 shifted so that the upper and lower amplitude of the support means 232 ie the foot plate 23 changed. (The upper and lower amplitudes gradually increase.) (See Figs. 5a and 5b) 5 .)

When the rotary shaft 432 on the other hand is rotated in the opposite direction, then the conveyor body 433 moved forward, and thus the support 42 along the lever 41 forward so that the starting point is moved. In doing so, the upper and lower amplitude of the assisting means decreases 232 ie the foot plate 23 gradually.

Further, when the predetermined movement path is reached in the amplitude change, then the limit switches transmit 62 of the over wachungsmoduls 60 the control unit 2c the touch signal, and thus depending on the control of the touch signal receiving controller 2c the forward and reverse drive motor 431a off. Accordingly, the starting point of the Auflagers 42 only within that through the monitoring module 60 shifted movement path.

The top of two representation parts of the 6 schematically represents a state before the amplitude change, and the lower side another state in which the amplitude change occurs, so that the amplitude changes greatly.

Subsequently, it is due to the two parts of the representation of 6 explained in more detail. Before the change of the support 42 is the upper and lower up and down movement of the through the cam 32 up and down elliptically moving interconnecting body 33 h1, wherein the up and down movement width of the support means 232 h2, that with the starting from the support 42 the up and down movement performing lever 41 is coupled.

After the change of the support 42 ie when the conveyor body 433 by the forward and reverse drive means 431 moves backwards, then becomes the starting point of the support 42 shifted backwards so that the up and down movement width of the lever 41 coupled supportive means 232 is increased by h3 at the state where the up and down movement width h1 does not change.

In contrast, if the conveyor body 433 by the forward and reverse drive means 431 is moved forward under the state before the change, then the up and down movement width of the support means 232 reduced to the lower than h2.

In addition, the rotation angle of the rotary shaft 432 through the rotation angle monitoring module 50 detected, the light sensor 52 concerning the toothed disc 51 detects a rotation angle and the detected values in the memory 53 of the control unit 2c and a current state of change on the display 2a is shown. Accordingly, a help function is provided which allows that, due to the detected, in memory 53 stored values, it can be informed of a current state of change just when restarting after the power failure or shutdown.

Obwhol the inventive, "amplitude-controlled Vibration device "above based on attached Drawings essentially with respect to their specific ones Embodiments and structures is described, it can by a person skilled in the art be transformed and changed in various ways, and thus these transformations and changes as considered within the scope of the invention be.
