DETAILED DESCRIPTION OF VARIOUS EMBODIMENTS

(7) FIG. 1 shows a side view of hair clippers having a housing 2, on the front side of which is arranged a cutting assembly 3 comprising a clipping comb 4 and a clipping blade 5, which is arranged above the latter such that it can be driven in oscillation. An oscillating movement of the clipping blade 5 can be generated by a hair-clippers drive arranged in the housing 2.

(8) FIG. 2 shows the hair clippers from FIG. 1 with the cutting assembly 3 swung down.

(9) This illustration shows the construction of the cutting assembly 3 to particularly good effect. A cutting compression spring 7, which is arranged on the clipping comb 4, subjects the clipping blade 5 to a contact pressure, which prevents hair from jamming between teeth arranged on the front side of the clipping comb 4 and the clipping blade 5, which would result in the cutting assembly 3 blocking. An oscillation movement of the drive is transmitted to the clipping blade 5 via a driver 6. The driver 6 is arranged on the drive side of the clipping blade 5 and has an engagement device for a stub which is arranged on the front side of the drive and is intended for transmitting the oscillation movement.

(10) FIG. 3 illustrates a cutting-assembly mount 1 as is used on the front side of the hair clippers from FIGS. 1 and 2. FIG. 3 shows a sectional illustration of the cutting-assembly mount 1, and this allows the construction of the latter to be shown to particularly good effect.

(11) The cutting-assembly mount 1 is formed essentially from an accommodating base 10, on which an accommodating limb 20 is arranged in a pivotable manner. The accommodating limb 20 is of essentially L-shaped design in side view and is mounted on the accommodating base 10 such that it can be pivoted via a pivot pin 18. Also mounted on the pivot pin 18 is a blocking element 30, the latter such that it can be displaced parallel to the accommodating limb 20. The blocking element 30 has a U-shaped guide 34, by which it engages over the pivot pin 18 and can thus be displaced along the accommodating limb 20. The accommodating limb 20 is subjected, on its rear side, to the action of a leaf spring 12, which is arranged on the accommodating base 10 and is of arcuate configuration such that a rear portion of the accommodating limb 20 slides into the arc and thus, as a result of the spring-loading, causes the accommodating limb 20 to open, i.e. swing down. On its side which is directed toward the accommodating limb 20, oriented in the direction of the pivot pin 18, the accommodating base 10 has a stop edge 13, against which the blocking element 30, which in the present example is designed as a blocking catch 30, strikes in the blocking position and can thus block the cutting-assembly mount 1 from swinging closed. For this purpose, the blocking catch 30 has a blocking step 32 which, when the blocking catch 30 is located in the blocking position, strikes against the stop edge 13.

(12) The blocking catch 30 is illustrated in two different positions in FIG. 3, wherein a position in which it is disengaged in the frontward direction (illustrated by dashed lines) constitutes the blocking position of the blocking catch 32. That position of the blocking catch 30 which is illustrated by solid lines constitutes an intermediate position, in which the blocking catch 30 has been displaced in the direction of the pivoting position. The pivoting position is reached as soon as a front edge of the blocking step 32 can slide past the stop edge 13.

(13) Spring-loading of the blocking catch 30 is achieved by a compression spring which engages in the engagement opening 36 and thus loads the blocking catch 30 in the frontward direction. Such a compression spring may be supported, for example, in the rearward direction, on the L-shaped accommodating limb 20 or on the pivot pin 18.

(14) FIG. 4 shows a plan view of the cutting-assembly mount 1 from FIG. 3. It is only the accommodating base 10 with the pivot pin 18 arranged thereon which is illustrated, the accommodating limb 20 having been omitted in order to give a better view of the blocking mechanism.

(15) This plan view shows that the present exemplary embodiment has two blocking catches 30, which are spaced apart from one another on the pivot pin 18. This makes it possible to achieve uniform distribution of force over the accommodating base for the case where, despite the blocking catch 30 being located in the blocking position, an attempt is made to swing the cutting-assembly mount closed. Furthermore, the cutting-assembly mount 1 is prevented from being swung closed if the cutting assembly 3 is inserted in a skewed state, and therefore incorrect operation, in this way, is ruled out.

(16) The blocking catches 30 are illustrated in the blocking position in FIG. 4. This is evident in that a front edge of the blocking catches 30 overlaps with the stop edge 13 of the accommodating base 10 and thus strikes against the same. In order to accommodate the blocking catches 30 in the pivoting position, the accommodating base 10 has two recesses 19, into which the blocking catches 30 can penetrate when they are pushed in the direction of the pivot pin 18 by the cutting assembly 3, and therefore a pivoting movement of the accommodating limb 20 is released.

(17) The pivot pin 18 is retained on the outside of the accommodating base 10 via two bearing bushings 16, which in the present exemplary embodiment are formed in one piece on the accommodating base 10.

(18) The accommodating base 10 also has two fastening bores 14, by way of which the accommodating base 10 can be fastened on the hair clippers by two screws.

(19) FIG. 5 shows a second exemplary embodiment of a cutting-assembly mount 1 according to the system described herein. The cutting-assembly mount 1 according to FIG. 5 differs from the cutting-assembly mount 1 according to FIG. 4 in that the blocking element 30, rather than being designed as a blocking catch, is designed as something of an angled blocking element 30. A corresponding angled blocking element 30 has a blocking nose 39 which, in the blocking position of the angled blocking element, strikes against the accommodating base 10 and thus blocks a pivoting movement of the accommodating limb 20 in the direction of the accommodating base 10. As is illustrated in FIG. 5, such an angled blocking element 30, depending on how it is mounted, can be transferred from the blocking position into the pivoting position in two ways.

(20) In a first variant, the angled blocking element 30 is mounted on the pivoting pin 18 and is designed such that it can be displaced along the pin 18. In order for the angled blocking element 30 to be transferred from the blocking position into the pivoting position, a run-up edge 37 is provided, this being designed such that it transfers a linear pushing-on movement of the cutting assembly 3 in the direction of the pivot pin 18 into a linear movement of the angled blocking element 30 parallel to the pivot pin 18. In this way, the blocking nose 39 is likewise displaced parallel to the pivot pin 18 and can thus be transferred from being positioned above the accommodating base 10 into a position in the region of one of the recesses 19. The blocking nose 39 is then arranged such that it penetrates into the recesses 19 and thus allows a pivoting movement of the accommodating limb 20 in the direction of the accommodating base 10.

(21) In this embodiment, spring-loading of the angled blocking element 30 can be achieved particularly straightforwardly, for example, by a helical spring arranged on the pivot pin 18.

(22) In a second embodiment, the angled blocking element 30 is mounted in a pivotable manner either on the accommodating base or on the accommodating limb and is pivoted, by virtue of the cutting assembly 3 being plugged on, into a position over the recess 19, and therefore, in this position too, a pivoting movement between the accommodating limb 20 and accommodating base 10 is released.

(23) There is also, in principle, a series of further options which are intended for configuring a cutting-assembly mount 1 with a blocking element 30 and can be realized without deviating from the basic concept of the system described herein. In particular, a possible configuration of the accommodating base 10, accommodating limb 20 and blocking element is one in which the recess 19, rather than being provided in the accommodating base 10, is provided on the accommodating limb 20 or on the blocking element 30.

(24) Various embodiments discussed herein may be combined with each other in appropriate combinations in connection with the system described herein. Additionally, in some instances, the order of steps in the flowcharts, flow diagrams and/or described flow processing may be modified, where appropriate.

(25) Other embodiments of the invention will be apparent to those skilled in the art from a consideration of the specification or practice of the invention disclosed herein. It is intended that the specification and examples be considered as exemplary only, with the true scope and spirit of the invention being indicated by the following claims.
