Abstract
The invention is directed to a dry shaving apparatus having a housing (1) and a housing portion (21) in which at least one exchangeable frame (20) incorporating at least one cutting element (18) is held by at least one detent means (28, 29), with cooperating stop elements (40, 50, 60, 70) being provided on the exchangeable frame (20) and on the housing portion (21), wherein the stop elements (40, 50, 60, 70) are maintained in engagement by means of at least one pressure element (30, 31) acted upon by a spring element (32, 33) and bearing against a wall (39), and by means of a sloping wall surface (34, 35, 36, 37) acted upon by the pressure element (30, 31), and wherein the pressure element (30, 31) and the sloping wall surface (34, 35, 36, 37) are provided to take effect only on one side of the cooperating stop elements (40, 50, 60, 70).
Claims20
A dry shaving apparatus comprising:
- a housing;
- a housing portion mounted on the housing and having a first inner wall and a second inner wall opposite the first end wall;
- a biasing mechanism including a pressure element, a spring element, and a bearing wall;
- at least one exchangeable frame incorporating at least one cutting element and having a first end wall on one end and a second end wall on an opposite end, one of said first inner wall and said first end wall defining a sloping wall surface;
- and
- at least one detent element holding the exchangeable frame onto the housing portion so that said first end wall abuts said first wall and said second end wall abuts said second wall, said frame having a first stop element that cooperates with a corresponding second stop element of the housing portion, wherein the first and second stop elements are maintained in engagement with each other by said spring element acting upon said pressure element and causing said pressure element to both bear against said bearing wall and act upon said sloping wall surface, and wherein said spring element has a direction of force and the sloping wall surface slopes with respect to a plane that is normal to the direction of force.
The dry shaving apparatus as claimed in 1, wherein the housing defines a vertical center line, the direction of the force of the spring element being oriented parallel to the vertical center line.
