Furthermore, it has a flexible toothed ring which is coaxial within both circular ones Cassettes is arranged and the same number of teeth as the first circular sprocket has, and a coaxial cam on the rotary element for deformation of the flexible toothed ring in a non-circular configuration to the Tooth ring in a partial engagement with the teeth of the first and second circular To bring sprocket and to rotate the deformed configuration of the toothed ring, to finally a relative movement between the first and second sprocket and thus an adjustment of the reading indicator cause.
The use according to the invention a suitable differential gear therefore causes depending on the chosen gear ratio that by turning the rotary element on the setting or Dosierknopf, z. B. 360 °, a specific slight rotational movement of the indicator takes place, which in turn is in a relation to a specific setting or dosing value.
outgoing from the case the setting or Dosierknopfes, which preferably cylindrical is formed, this housing already forms the outer part of the differential gear, d. H. the first circular sprocket the transmission is advantageous as internal teeth within the housing one piece provided with this, further wherein the housing at its periphery a window for the Reading the respective values of the indicator has.
Of the second sprocket, the longitudinal the axis of the first sprocket is disposed adjacent thereto, is on the other hand as internal toothing in a cylindrical display drum one piece provided with this, the advantageous at the same time on its outer jacket has the scaling.

In terms of the polygon of the adapter in this case, the connection portion of the rotary member has a corresponding have trained inner edge.
The concentric structure of the setting or Dosierknopfes invention advantageously allows only an axial bearing for all components. Also, a quick assembly is possible because all components can be easily assembled axially, the number of components is kept extremely low, ie it is not more than four essential items needed. Finally, for a quick and uncomplicated assembly of the adjusting or metering heads according to the invention, it is particularly expedient for the cylindrical housing, which can be plugged axially via the cylindrical display drum, to be replaced by a snap-action connector Binding is held on the control handle.
Further Features and advantages of the present invention will become apparent the following description of several embodiments in conjunction with the drawing; show it:
1.1 - 1.6 a schematic representation of the individual components of a control or Dosierknopfes invention and
2.1 - 2.5 a schematic representation of the control or Dosierknopfes according to 1 in five different positions during a full rotation of its control handle and cross sections through the changing in its position according to the rotation progress differential gear with an elliptical cam;
3 a schematic plan view of a further embodiment of an inventive differential gear.
4 a plan view of another embodiment of an inventive differential gear.
In 1 are the individual components 1.1 - 1.6 of an adjusting or Dosierknopfes shown schematically, namely designated 1 in 1.1 a rotary element consisting of a cylindrical control handle 2 and a shaft part integrally attached thereto 3 consists. The trained as a rotary knob handle 2 has on its conical collar a circumferential scale 4 and the shaft part 3 a coaxially arranged and elliptical in cross-section formed cam 5 , Further, in the shaft part 3 at its free end the front side a square socket 6 formed.
1.2 shows a flexible plastic ring gear 7 which belongs to the differential gear used in the present invention and whose inner peripheral surface has a length corresponding to the outer circle of the elliptical cam 5 corresponds so that the toothed ring 7 fed axially on the cam 5 in 1 can be pushed or pushed.
In 1.3 is the case - labeled with 8th - The differential gear shown schematically in section, which is formed as a cylinder ring and flattened at its periphery at one point, creating a window 9 is obtained, which is used for reading position or Dosierwerten. Further, on the inner surface of the plastic housing 8th a circular first sprocket 10 formed in the shape of an internal toothing.
1.4 shows as a further component of the transmission a cylindrical display drum 11 in section, which is also made of plastic and an internal toothing as a second sprocket 12 own, which is also an integral part of the display drum 11 is. The width of the sprocket 12 corresponds to the width of the first sprocket 10 in the case 8th and corresponds to about half the width of the display drum 11 ,
1.5 shows a relatively thin plastic ring 13 , on the outer shell of a scale 14 is applied and the according to the arrow (b) in 1.5 axially on the outer jacket of the display drum 11 is pushed or pushed.
For connecting the shaft part 3 of the rotary element 1 with a setting object, not shown, a plug connection is provided for the execution in 1.6 schematically an adapter 15 is shown, at one end of a square 16 and his other end a blind hole 17 is provided, a grub screw connection 18 has.
According to the shape of the square 16 is then also in the shaft part 3 of the rotary element 1 the square socket 6 educated.
After all, that's about the cylindrical display drum 11 Coaxial pluggable cylindrical housing 8th through a snap connection 20 on the control handle - indicated in 1.1 - held.
The assembly and operation of the present invention is as follows: The in 1.1 - 1.6 The components shown are assembled or assembled by first the toothed ring 7 according to arrow (a) coaxial with the housing 8th is pushed into, until its teeth from the teeth of the toothed ring 7 completely covered. Then the scaling 14 according to arrow (b) axially on the display drum 11 inserted flush and coaxial with the arrow (c) in the housing 8th pushed. Then this unit becomes coaxial with the shaft part 3 as indicated by arrow (d), so that it is the toothed ring 7 over the elliptical cam 5 lays and the housing 8th with its free edge over the conical collar of the control handle 2 at 20 snaps. With these few steps, the adjusting or dosing knob according to the invention is thus assembled or mounted in a simple manner.
For a connection of the thus assembled control or Dosierknopfs to a setting object then only the adapter must in accordance with 1.6 with his square 16 in the square socket 16 of the shaft part 3 be plugged axially, here similar to in 1 .6 shown, the square 16 can be clamped with a grub screw. But it is also possible to additionally or exclusively accomplish the attachment of the control or Dosierknopfs by a countersunk screw, which from the front side of the control handle 2 out into the front of the square 16 is screwed (not shown).
Furthermore, it may also be expedient in this context, the rotary member 1 only as a hollow shaft 19 with z. B. form a grub screw connection to just put it on a connecting shaft can. The latter solution is also taken over by the adapter 15 with his subject hole 17 and the grub screw 18 ( 1.6 ).
The operation of the present invention will be described below with reference to 2 explained in more detail, and that is in the 2.1 - 2.5 each according to the 1.1 - 1.5 Assembled control or Dosierknopf shown schematically in different operating phases.
2.1 shows the starting phase, in which the control handle 2 with his scale 4 is at "zero position" and the display drum 11 with their scaling 14 At the same time the elliptical cam is displayed 5 with its main axis horizontal, so that the flexible toothed ring 7 in its two vertices 21 and 22 with the affected teeth of both circular sprockets 10 and 12 within the housing 8th is engaged.
Now the control knob 2 rotated clockwise by 90 ° ( 2.2 ), then on the one hand moves the main axis of the elliptical cam 5 in a vertical position and the described engagement of the deformed toothed ring 7 is done in the same way, and on the other hand scaling is going on 14 counterclockwise by a small amount.
The process is then repeated as in the 2.3 - 2.5 represented, ie in 2.3 is the control handle 2 around 180 °, in 2.4 around 270 ° and in 2.5 been turned around a full turn. As soon as a full turn of the control handle 2 reached is the scale 4 of the control handle 2 again at the position "0" and the scaling 14 has advanced exactly by a large scale counter-clockwise.
The ratio of the two rotational movements between the control handle 2 and the display drum 11 depends on the gear ratio of the differential gear, and that is calculated according to the formula
= Number of teeth of the first sprocket 10
= Number of teeth of the second sprocket 12 .
whereby here tooth number differences of 2, (4), are possible.
Hereby have the sprocket 10 in the case 8th and the toothed ring 7 the same number of teeth, so that these two components when turning the rotary element 1 not be adjusted in their position to each other. The second sprocket 12 in the display drum 11 on the other hand has a different number of teeth, so that when rolling the toothed ring 7 along the second sprocket 12 this one turned becomes.
While 2 shows the embodiment of the invention with an elliptical differential gear is in 3 indicated that the arrangement of an eccentric differential gear is possible. Here is a toothed ring 7.1 round and sitting on a cylindrical eccentric cam 23 on. The eccentric cam 23 is in place of the cam 5 provided and a rotating element 1.1 instead of the cam 5 formed. It rotates eccentrically around an axis A of the rotary element.
The toothed ring 7.1 also engages in position of use, like the toothed ring 7 , in the first and second sprocket 10 respectively. 12 the display drum 11 or of the housing 8th a, wherein the ratio of the number of teeth may be the same as in the elliptical drive. Also, the formula of the translation is the same, but the possible number of teeth differences are 1, 2 (3), ....
According to 4 is in place of the cam 5 or the eccentric cam 23 a polygonal sock 24 provided on the the toothed ring 7.2 is plugged. In the present embodiment, the polygonal cam is triangular in shape, but it may also have a different number of engagement portions. Also in this embodiment, the formula for the translation is the same, but there are the following possible number of teeth differences: 3, (6), ....
Overall, with the present invention, a purely mechanical actuator or Dosierknopf created advantageous only requires an axial bearing for all transmission components by its concentric structure, ie all components can on one axis - in this case the rotary element axis - are mounted, creating an extraordinary Low tolerance is achieved. Furthermore, the measured value display and the transmission form a unit, at the same time the internal gears 10 and 12 each in the associated components 8th and 11 are integrated, which also fewer items are present, which must be mounted and may also be lost. Last but not least, the display drum has 11 a multiple function, and indeed serves as storage, gear, display and scale protection, as this only through the window 9 is visible, so for scaling 14 It is also possible to use only printed paper strips (eg also custom-printed) and the like. Finally, the invention allows a simple and quick installation of the control or Dosierknopfes, which is still supported by the proposed snap technology. The button presents itself to the consumer in its size relatively small and compact in its design.
