Abstract
The invention relates to an electrohydraulic pressing device (1) that can be operated using one hand. The device comprises a working head (30), an electric motor (4), a pump (20), a hydraulic reservoir (33), and a gear mechanism (19) extending between the electric motor (4) and the pump (20). A holding area (5) around which a hand is placed is provided and an actuating switch (39) is assigned to this area. The aim of the invention is to improve a pressing device of this type with regard to the handling thereof. To this end, the invention provides that the holding area (5) is formed around the electric motor (4), and the actuating switch (39) is situated between the electric motor (4) and the working head.
Claims15
Electrohydraulic pressing device suitable for one-handed operation, comprising:
- a housing having a forward end and a rearward end;
- a working head attached to said housing, said working head provided at said forward end of said housing;
- an electric motor for actuating said working head, said electric motor being rearward of said working head, provided within said housing and being axially aligned with said working head;
- a hydraulic tank which houses hydraulic fluid, said hydraulic tank being rearward of said working head and provided within said housing;
- a pump for pumping hydraulic fluid from said hydraulic tank to said working head, said pump being rearward of said working head and provided within said housing;
- and
- a gear mechanism connected between the electric motor and the pump, said gear mechanism being rearward of said working head and provided within said housing;
- said housing defining a gripping region around which one hand of a user can be placed, said gripping region is formed around the electric motor such that in use, the hand of the user at least partially encircles the housing around said electric motor;
- and
- an actuating switch for actuating said working head, said actuating switch provided on said housing and being forward of said gripping region such that in use, the hand of the user can actuate said actuating switch while gripping said gripping region.
Electrohydraulic pressing device suitable for one-handed operation, comprising:
- a housing having a center of gravity and defining a forward end and a rearward end;
- a working head attached to said housing, said working head provided at said forward end of said housing;
- an electric motor for actuating said working head;
- a hydraulic tank which houses hydraulic fluid;
- a pump for pumping hydraulic fluid from said hydraulic tank to said working head;
- and
- a gear mechanism connected between the electric motor and the pump, said electric motor, pump, hydraulic tank and gear mechanism being rearward of said working head and provided within said housing;
- said housing defining a gripping region around which one hand of a user can be placed, said gripping region is formed around the electric motor;
- and
- an actuating switch for actuating said working head, said actuating switch provided on said housing and being forward of said gripping region;
- and
- an emergency switch provided on said housing, the gripping region is formed at the center of gravity of the housing and the actuating switch and the emergency switch are formed lying oppositely on the housing, appropriately for placement of an index finger/thumb.
Electrohydraulic pressing device suitable for one-handed operation, comprising:
- a housing defining a forward end and a rearward end;
- a working head attached to said housing, said working head provided at said forward end of said linear housing, said rear end of the housing is widened relative to a remainder of said housing;
- an electric motor for actuating said working head;
- a hydraulic tank which houses hydraulic fluid;
- a pump for pumping hydraulic fluid from said hydraulic tank to said working head;
- and
- a gear mechanism connected between the electric motor and the pump, said electric motor, pump, hydraulic tank and gear mechanism being rearward of said working head and provided within said housing;
- said linear housing defining a gripping region around which one hand of a user can be placed, said gripping region is formed around the electric motor;
- and
- an actuating switch for actuating said working head, said actuating switch provided on said housing and being forward of said gripping region, said actuating switch is formed on a side of said housing, the widened rear end projects to the side of said housing on which the actuating switch is formed.
