Abstract

Mechanical inversion of direction of a rotating control component of a landscape sprinkler device. Such a device, having a switching member with end stops associated therewith in both pivoting directions the control component, against said stops the switching member stops and is actuated, wherein at least one end stop can be adjusted coaxially with respect to a pivoting axis of the control component. The switching member is configured in an elastically resilient manner on the contact region thereof that is positioned at the height of the end stops such that the contact region retreats back from the adjusting path of the end stop in case of an overload, and devices are provided in order to re-establish the contact region at a defined position in the rotation angle region between the two end slops from the retreated position.

Claims

1. A device for the mechanical reversal of direction of a rotatable control component of a landscape watering device comprising:

a stationary housing comprising;

two adjustment rings, wherein each of the two adjustment rings has an annular flange and an end stop at the same horizontal level, wherein each of the annular flanges has one recess near a corresponding one of the end stops, wherein at least one of the two end stops can be adjusted coaxially with respect to an axis of rotation of the adjustment rings, wherein the annular flange and the corresponding end stop form an adjustment path; and

the rotatable control component comprising;

an elastic switching member, wherein the switching member includes;

a switching pin having a stationary area mounted on the rotatable control component and a contact area, the contact area positioned at the same horizontal level as the corresponding end stop and the annular flange of the adjustment rings, thereby the contact area of the switching pin is placed within the adjustment path; and

wherein, in case of an overload, one of the two end stops pushes the corresponding contact area of the switching pin to withdraw from the adjustment path through a corresponding recess in the annular flange in a line direction tangent to the adjustment path configured to mechanically reverse the direction of the rotatable control component.

2. The device according to claim 1, wherein the contact area is implemented to be elastically resilient as a function of force.

3. The device according to claim 2, wherein the contact area has a load limit in which the contact area yields elastically, the load limit is greater than a load required for switching the switching member.

4. The device according to claim 2, wherein the contact area has a load limit in which the contact area yields elastically, the load limit is greater than a load limit at which an overload safety device between the rotatable control component and a stationary housing part yields.

5. The device according to claim 1, wherein both adjusting rings are implemented with identical construction and are mounted in installation positions which are reversed with respect to one another.

6. The device according to claim 1, wherein the rotatable control component provides in the vicinity of the contact area and on both sides a bent lug as well as a deflection area in which the contact area is positioned in its elastically bent deflection position.

7. The device according to claim 1, wherein the contact area is formed by a spring element.

8. A landscape watering device with a rotatable control component and a stationary housing according to claim 1.

9. The device according to claim 1, wherein the switching member comprises a tillable switching pin which is provided with the elastically resilient contact area.

10. The device according to claim 9, wherein the switching pin is disposed eccentrically with respect to an axis of rotation of the control component and that the contact area projects axially into at least one stationary functional part which flanks the contact area both radially inwards and radially outwards.

11. The device according to claim 10, wherein an end stop is associated with the at least one stationary functional part and the at least one stationary functional part is formed as an adjusting ring which can be adjusted with respect to the housing part and can be arrested in various adjustment positions.

12. The device according to claim 11, wherein adjacent to the first adjusting ring and as an additional functional part, an additional adjusting ring which can be adjusted with respect to the housing part and can be arrested in various adjustment positions.
