Definitions

  • the invention relates to a dry shaving apparatus with a housing, a removable shaving head frame carrying the upper knife and a device for locking and unlocking the shaving head frame, consisting of locking elements movably arranged in the housing, which, under spring pressure, protrude from the narrow sides of the housing and into the Front cheeks of the shaving head frame arranged operating elements acting on the locking elements.
  • a dry shaving apparatus according to the preamble of claim 1 is known from DE-DS 25 19 881.
  • the disadvantages of such a construction are that in order to overcome the locking pressure forces and oppositely directed tensile forces must be applied to the shaving head frame and housing at the same time, which complicates the fact that the force component of the compressed locking spring acts on the control element via the locking element at a right angle and thus the removal process unfavorably burdened. Since the tensile forces to be exerted on the shaving head frame and housing must be greater than the force components of the locking springs, the unlocking process takes place in a jerky manner, which is perceived by the user as unpleasant.
  • the object of the present invention is to provide a device for locking and unlocking a shaving head frame which does not have the disadvantages mentioned above.
  • the device is intended in particular to ensure that the shaving head frame is easily removable or attachable from the housing.
  • leading ramps are provided on the inner walls of the end cheeks for the latching position of the locking elements and that in radially movable operating elements are arranged in the end cheeks, the walls of which act on the locking elements in the actuated state form discharge ramps for the locking elements.
  • the easy removal of the shaving head frame from the housing is achieved via the operating elements arranged in the forehead cheeks, which bend or rotate under the action of pressure around their attachment point and in this state form discharge ramps for which, during the course of this process, locking elements are pushed out from the locking positions.
  • the operating elements pressed into the shaving head frame come into contact with the locking elements at an angle, as a result of which the force component resulting from this angular position pushes the shaving head frame away from the housing via the discharge ramps.
  • the control element preferably consists of a resilient or pivotally mounted lever arm which is arranged in a recess provided in the front cheek of the shaving head frame.
  • One end of the lever arm is expediently fastened to a transverse web provided in the recess and, with its end acting on the locking element, lies against the inner wall of the forehead cheek in the idle state.
  • the inner wall of the lever arm serves as a discharge ramp, the inclination of which results according to the invention during the actuation process of the lever arm as a function of its radial deflection.
  • the ramp inclination of the downward ramp of the lever arm can preferably be changed beyond the blocking effect of the upward ramp.
  • the particular advantage of this measure can be seen in the fact that the separation process of the shaving head frame and the housing can be accelerated during the sliding of the locking elements on the discharge ramps of the lever arms by increasing the radial deflection of the lever arms and the resulting change in the ramp inclination.
  • a ramp is provided on both sides of an operating element on the end cheeks of the shaving head frame.
  • the walls leading from the slope end of the discharge ramps to the inner walls are preferably designed as detent stops for the locking elements.
  • FIG. 1 shows a dry shaving apparatus with a shaving head frame 2 which can be removed from a housing 1.
  • a shaving head frame 2 which can be removed from a housing 1.
  • an upper knife 3 is fastened, which interacts with a lower knife 4, which is set in a reciprocating motion by a motor, not shown, accommodated in the housing 1, via a rocker arm 5.
  • a helical spring 6 presses the lower knife 4 against the upper knife 3 in a known manner.
  • the end faces 7 and 8 of the housing 1 and the end cheeks 20, 21 of the shaving head frame 2 are identical, so that only one of the end faces with one of the end cheeks is referred to and described in more detail below.
  • locking elements 9 protrude from the two end faces 7 and 8 of the housing 1.
  • the locking elements 9 are, e.g. 2 shows, together with the compression springs 11 acting on them, housed in recesses 13 in the housing 1 and by means of resilient locking lugs 15 which engage in grooves 17 of a predetermined length provided in the walls of the recesses 13 to prevent them from falling out of the recesses 13 and torsion secured.
  • the end of the locking elements 9 protruding from the recesses 13 is conical, the cone tip being flattened or rounded.
  • the wall of the housing 1 is offset somewhat inward in the area of the shaving head frame 2, as a result of which a circumferential ledge 19 is formed which serves as a deflection for the shaving head frame 2 when it is placed on the viewing housing 1.
  • narrow U-shaped recesses 22 are provided, running in the longitudinal direction of the end cheeks and from the end of the shaving head frame 2 seated on the ledge 19, leading to the level of the locking elements 9.
  • an operating element 24 in the form of an elongated button, rotatable or, as shown, resilient.
  • a wide transverse web 42 is provided in the recesses 22, to which the operating elements 24 made of resilient material are fastened, e.g. through a clip connection.
  • the crossbars 24 can also be mounted as a round rod and rotatably in the recesses in order to rotate a deflection, e.g. rigidly designed controls.
  • control elements 24 facing away from the ledge 19 lie on the one hand on the locking elements 9 and on the other hand on the inner walls 26 of the end cheeks 20 and 21, the control elements 24 and the inner walls 26 being provided with interlocking shoulders 28 and 30 in the contact area.
  • Projections 32 are provided on the operating elements 24, which in the locked state of the shaving head frame 2 and the housing 1 from the recesses 22 and out of the outer contour of the Stirnwan - protrude gen. 20 and 21
  • the elevations 32 denote the pressure range for the unlocking process on the control elements 24.
  • the shaving head frame 2 stands out from the ledge 19 of the housing 1.
  • the unlocking process is initially supported and facilitated by the fact that, in the locked state of the shaving head frame 2 on the housing 1, the existing contact pressure of the lower knife 4 on the upper knife 3 fastened in the shaving head frame 2 can also be used.
  • the operating elements 24 are in the position shown in FIG. in contact with the inner walls 26 of the end cheeks 20 and 21.
  • the shaving head frame 2 is pushed over the recessed area of the housing 1, the locking elements 9 coming into contact with the run-up ramps 34, 35, the gradual gradients provided for the locking elements 9 against the pressure of the Push the compression springs-11 into the recesses 13.
  • the compression springs 11 press the locking elements 9 partially out of the recesses 13 into the latching position, this process being supported by the obliquely designed latching stops 38 and 39 and the inclined surfaces provided on the locking elements 9 .
  • Fig. 4 shows a part of the housing 1 of the razor with a locking element 9 protruding from the end face 8, the ends of which are chamfered and extend transversely to the end face.
  • An identically designed locking element is provided in the end face 7.
  • the end cheeks 20 and 21 of the shaving head frame 2 are connected to one another via a front wall 36 and a rear wall 37 shown in broken lines.
  • two run-up ramps 34 and 35 are provided, with an increasing gradient in the removal direction.
  • the return of the run-up ramps to the inner wall 26 results in locking stops 38 and 39, the walls of which are chamfered, corresponding to the bevel of the ends of the locking elements 9, which come into contact with these locking stops in the locking position.
  • the resilient or pivotable operating element 24 is arranged in a U-shaped recess, the end of which lying in the removal direction bears either on the inner wall 26 of the front cheek 20 or, as shown here, on the immovable foot part of a further operating element 25 .
  • the end cheek 21, the inner wall is not visible due to the perspective-v regard representation, has an identical with the inner wall 26 of the end cheek 20 training. This also applies to the outer walls of the front cheeks 21 and 20, which only show the operating elements 24 and 25 with the respective elevations 32 and 33 running in the longitudinal direction of the front cheeks.
