Abstract
A manually operated press comprising an actuating member coupled to a shaft, wherein an actuation of the actuating member is converted into a stroke movement of a press ram coupled to the shaft, and hence also into a change in a relative position of the press ram. The press furthermore comprises a reset mechanism for resetting the actuating member, which reset mechanism counteracts the actuation of the actuating member and causes a return movement of the press ram opposite the stroke movement. The reset mechanism comprises a spiral spring.
Claims17
A manually operated press, comprising:
- a shaft;
- an actuating member coupled to the shaft;
- a press ram coupled to the shaft;
- and
- a reset mechanism that is configured to reset the actuating member;
- wherein an actuation of the actuating member is converted into a stroke movement of the press ram;
- wherein the reset mechanism is configured to counteract the actuation of the actuating member and to cause a return movement of the press ram opposite the stroke movement,
- wherein the reset mechanism comprises a spiral spring,
- wherein a radially inner end of the spiral spring is attached to the shaft,
- wherein the spiral spring comprises a first connecting link at the radially inner end,
- wherein the first connecting link comprises a curved portion that is integrally connected to the spiral spring, and
- wherein the shaft comprises a web that is oriented parallel to a longitudinal axis of the shaft, wherein a cavity is arranged between the web and an outer side of the shaft facing towards the web, and wherein the first connecting link engages in the cavity.
