Definitions
- the invention relates to a shaving apparatus comprising a cutting unit which comprises a first cutting member with hair-entry apertures and a second cutting member which is rotatable relative to the first cutting member, which second cutting member is coupled to a drive mechanism by means of a spindle, which spindle comprises two portions which are movable relative to each other in a substantially axial direction, a first spindle portion having a coupling end which is situated in a recess in a second spindle portion and which is formed with a flange which is retained in said recess by means of elastically deflectable limbs formed by wall portions of the second spindle portion.
- a shaving apparatus is disclosed in, for example, US-PS 4,257,161.
- the invention aims at providing a coupling of minimal dimensions between the cutting unit and the drive mechanism and is characterized in that the elastically deflectable limbs extend substantially tangentially of the spindle and are directed at least partly inwards relative to the wall of the recess.
- a special embodiment is characterized in that the elastically deflectable limbs are formed on the ends of axial ridges in the recess of the second spindle portion.
- the shaving apparatus shown in Figure 1 comprises a housing 1 and cutting units 2, a cutting unit comprising a first cutting member 3 with hair-entry apertures 4 and a second cutting member 5 which is rotatable relative to the first cutting member 3.
- the second cutting member 5 is coupled to the drive mechanism 7 by means of a spindle 6.
- the spindle 6 (see Figures 2, and 4) comprises two spindle portions 8 and 9 which are movable relative to each other in a substantially axial direction.
- the first spindle portion 8 has a coupling end 10 with a flange 11. This flange 11 engages a recess 12 of the second spindle portion 9.
- the spindle portion 9 is provided with a gear ring 13 for the coupling to the drive mechanism 7.
- three ridges 14 are formed which extend in the axial direction and which are integral with the wall 15 of the recess 12. The ridges 14 engage in three recesses 16 in the flange 11, thereby imparting the rotation of the spindle portion 9 to the spindle portion 8.
- the flange 11 is retained in the recess 12 by means of elastically deflectable limbs 17.
- These limbs 17 extend from the ends 18 of the ridges 14, in a substantially tangential direction relative to the spindle, enabling the overall length of the spindle 6 to be minimized.
- In the assembled condition at least the ends 19 of the limbs 17 are situated above the portions 20 of the flange 11 which are spaced by the recesses 16, so that they effectively retain the flange.
- the portions 20 of the flange 11 are urged against said elastically deflectable limbs by the compression spring 21 which is enclosed within the spindle portions 8 and 9.
- the portions 20 of the flange may be formed with oblique guide faces 20 to facilitate the passage of these ends.
- the elastically deflectable limbs 17 extend in the circumferential direction from an end 18 of a ridge 15 to a point near the end 18 of an adjacent ridge.
- the portions 20 of the flange 11 should only cover a small circumferential or tangential distance, for example 1/6 of the circumference.

Abstract
Description
- The invention relates to a shaving apparatus comprising a cutting unit which comprises a first cutting member with hair-entry apertures and a second cutting member which is rotatable relative to the first cutting member, which second cutting member is coupled to a drive mechanism by means of a spindle, which spindle comprises two portions which are movable relative to each other in a substantially axial direction, a first spindle portion having a coupling end which is situated in a recess in a second spindle portion and which is formed with a flange which is retained in said recess by means of elastically deflectable limbs formed by wall portions of the second spindle portion. Such a shaving apparatus is disclosed in, for example, US-PS 4,257,161.
- The invention aims at providing a coupling of minimal dimensions between the cutting unit and the drive mechanism and is characterized in that the elastically deflectable limbs extend substantially tangentially of the spindle and are directed at least partly inwards relative to the wall of the recess.
- A special embodiment is characterized in that the elastically deflectable limbs are formed on the ends of axial ridges in the recess of the second spindle portion.
- An embodiment of the invention will now be described in more detail, by way of example, with reference to the Figures.
- Figure 1 shows a shaving apparatus having three cutting units in a side elevation and partly in cross-section.
- Figure 2 is a sectional view of the spindle.
- Figure 3 is a plan view of the spindle shown in Fig. 2.
- Figure 4 is a side elevation of a spindle portion of the spindle shown in Figs. 2 and 3.
- The shaving apparatus shown in Figure 1 comprises a housing 1 and
cutting units 2, a cutting unit comprising afirst cutting member 3 with hair-entry apertures 4 and asecond cutting member 5 which is rotatable relative to thefirst cutting member 3. For this purpose thesecond cutting member 5 is coupled to thedrive mechanism 7 by means of aspindle 6. - The spindle 6 (see Figures 2, and 4) comprises two
spindle portions first spindle portion 8 has acoupling end 10 with aflange 11. Thisflange 11 engages arecess 12 of thesecond spindle portion 9. Thespindle portion 9 is provided with agear ring 13 for the coupling to thedrive mechanism 7. In therecess 12 threeridges 14 are formed which extend in the axial direction and which are integral with thewall 15 of therecess 12. Theridges 14 engage in threerecesses 16 in theflange 11, thereby imparting the rotation of thespindle portion 9 to thespindle portion 8. Theflange 11 is retained in therecess 12 by means of elasticallydeflectable limbs 17. Theselimbs 17 extend from theends 18 of theridges 14, in a substantially tangential direction relative to the spindle, enabling the overall length of thespindle 6 to be minimized. In the assembled condition at least theends 19 of thelimbs 17 are situated above theportions 20 of theflange 11 which are spaced by therecesses 16, so that they effectively retain the flange. Theportions 20 of theflange 11 are urged against said elastically deflectable limbs by thecompression spring 21 which is enclosed within thespindle portions spindle portion 8 is fitted into thespindle portion 9 theends 19 of the limbs are pressed radially outwards to allow theportions 20 of theflange 11 to move past theseend 19. Theportions 20 of the flange may be formed with oblique guide faces 20 to facilitate the passage of these ends. The elasticallydeflectable limbs 17 extend in the circumferential direction from anend 18 of aridge 15 to a point near theend 18 of an adjacent ridge. Theportions 20 of theflange 11 should only cover a small circumferential or tangential distance, for example 1/6 of the circumference.
