Definitions
- the invention relates to a dry shaver according to the preamble of claim 1.
- a dry shaver of the type mentioned is known from the document DE 33 02 610 A1.
- the interchangeable frame arranged in a housing part is seated on the ledge of the housing by means of a flange and is coupled to the housing by means of a positive locking action which acts in the two working directions of a movable cutting element and which is formed by projections engaging in recesses.
- a housing part provided for receiving and holding an interchangeable frame can be detachably arranged on the housing of a dry shaving apparatus - see DE 33 02 610 A1 - and also firmly connected to the housing, i.e. Be part of the housing - see DE 44 10 543 C1, Fig. 10 -.
- Interlocking couplings between an interchangeable frame and a housing part of a dry shaving apparatus for the purpose of a vibration-free seat of the interchangeable frame require a movement-free contact of interacting form-locking elements, i.e. a gap-free form fit.
- a gap-free form fit can be produced with increased manufacturing effort, but it is susceptible to wear over a longer period of time due to abrasion or deformation of interacting form-fitting elements during use, so that the desired effect of permanently preventing the change frame equipped with at least one cutting element from oscillating is ruled out.
- a dry shaver of the type mentioned in which a wear-free fit of the removable frame is permanently guaranteed in a housing part, but in this known dry shaver additional means, such as arranged in the housing part, loaded by spring elements, movably mounted pressure elements provided that press the removable frame against a stop provided on the housing part.
- the object of the invention is to simplify the releasable attachment of an interchangeable frame to the housing part while ensuring a vibration-free attachment of the interchangeable frame to the housing part in a dry shaver of the type mentioned and to make it cheaper.
- a major advantage of the invention is that the already existing detachable locking devices that hold the removable frame on the housing part are used for a permanent vibration-free seat of the removable frame on the housing part, so that additional costs-causing components are saved.
- the latching force of the locking element can be converted into a positional force component and into a holding force component by means of a spatial alignment of the contact surfaces of the locking element and the contact surfaces of the removable frame.
- the vibration-free positioning of the removable frame is determined by the removable frame resting against a stop on the housing part under the influence of the positional force component on the contact surface of the removable frame.
- the stop is formed by an inner wall of the housing part. This measure does not cause any costs, for example, since an already existing wall of the housing part is used here as a system or support for the removable frame for the vibration-free seat. Any wear that occurs on the locking surfaces of the locking elements and also on the locking surfaces in the removable frame and also the interacting surfaces of the removable frame and the stop are automatically compensated for by the locking force of the locking elements.
- the stop is provided on an inner wall of the housing part.
- the inner wall is part of an end wall of the housing part.
- a preferred embodiment of the invention is characterized in that the position force component is effective only in one direction of the directions of vibration of the movable cutting element. This has the advantage that a corresponding course of the contact surfaces on the locking elements of the interchangeable frame can alternately be placed on the housing part and locked with it.
- the holding force component is effective against the removal direction of the removable frame from the housing part.
- two latching surfaces are provided on each longitudinal side wall of the change frame.
- a particularly advantageous embodiment of the invention is characterized in that, starting from a common zero point, the latching surfaces are formed obliquely to the x-axis, the y-axis and the z-axis.
- all the latching surfaces provided on the longitudinal side walls of the interchangeable frame are designed with respect to the stop with a course increasing in the coordinate axes x and y and x and z in relation to a common zero point.
- at least one locking surface is provided on the locking element in a further embodiment of the invention.
- two locking surfaces are provided on the locking element.
- the latter embodiment tion form the locking surfaces are wedge-shaped to each other.
- the alignment of the locking surfaces on the locking elements is essentially adapted to the alignment of the locking surfaces in the removable frame.
- the shape of the latching surface of the locking element is adapted to the latching surface of the interchangeable frame in such a way that the engagement of interacting latching surfaces is determined by a line-like contact.
- An alternative embodiment of the invention is characterized in that the contact of the locking surface of the locking element on the locking surfaces of the removable frame is determined by a point-like contact.
- the locking elements arranged in the housing part can be acted upon by a spring element.
- a spring element is preferably provided for acting on two locking elements which act in opposite directions.
