Abstract
A high-pressure washer has a housing and an actuator rotatably supported about an actuator rotation axis. A control element is arranged rotatably at the housing and is provided to control the actuator. The control element and the actuator are fixedly connected to each other for joint rotation by one or more universal joints.
Claims17
A high-pressure washer comprising:
- a housing;
- an actuator rotatably supported about an actuator rotation axis;
- a control element arranged rotatably at the housing and configured to control the actuator;
- the control element and the actuator fixedly connected to each other for joint rotation by one or more universal joints;
- wherein the one or more universal joints include a first universal joint and a second universal joint, wherein the control element and the actuator are arranged at a distance from each other, wherein the distance is measured in a direction of a control rotation axis of the control element, and wherein the control element and the actuator are fixedly connected to each other for joint rotation by the first universal joint and the second universal joint;
- a connecting member arranged between the control element and the actuator, wherein the first universal joint is formed between the control element and the connecting member and wherein the second universal joint is formed between the actuator and the connecting member;
- wherein the control element and the connecting member form a component group, wherein the component group comprises a state of use, wherein in the state of use the control element and the connecting member are movable relative to each other, wherein the component group further comprises a mounting state, wherein in the mounting state the first universal joint is non-pivotably locked by a releasable locking connection provided between the control element and the connecting member;
- wherein the releasable locking connection in the state of use is released such that the control element and the connecting member in the state of use are connected to each other by the first universal joint only such that pivoting of the connecting member relative to the control member is possible.

A high-pressure washer sprayer comprising:
- a housing;
- an actuator rotatably supported about an actuator rotation axis, wherein the actuator rotation axis extends along an actuator rotation axis direction;
- a control element arranged rotatably at the housing and configured to control the actuator;
- the control element and the actuator fixedly connected to each other for joint rotation by a connection provided by at least one universal joint;
- wherein the at least one universal joint comprises a first joint element and a second joint element, wherein the first joint element comprises a receptacle, and wherein the second joint element is supported in the receptacle of the first joint element and is pivotable relative to the first joint element;
- wherein the receptacle of the first joint element and the at least one universal joint are configured as a whole such that a movement of the second joint element in the receptacle of the first joint element relative to the first joint element is enabled in a direction parallel to the actuator rotation axis direction without opening the connection provided by the at least one universal joint;
- wherein the at least one universal joint is configured to enable a movement of the actuator relative to the control element along the actuator rotation axis direction without disengaging the connection provided by the at least one universal joint between the control element and the actuator.
