Personal care assembly
View Patent ↗A personal care apparatus includes a handle housing a rechargeable battery and a plurality of operating heads such as a vibrating safety razor head and a hair trimming device exchangeably mountable on the handle for assembling different hand-held appliances for performing respective body treatments. A base is included for storing the components of the apparatus when not in use and forms a battery charging device with a socket into which the handle plugs for recharging the battery. The operating heads include electrical devices, in particular electric motors, powered by the battery.
1. A personal care assembly comprising:
a handle including electrical contacts, and a battery compartment for accommodating a battery for supply of electric current to the electrical contacts;
a first operating head comprising a safety razor and a second operating head comprising a hair trimmer, wherein each of said first and said second operating heads are exchangeably mountable on the handle, wherein each of said first and said second operating heads comprises an electric device, and electrical contacts for cooperation with the electrical contacts on the handle for supply of electric current to the electric device when a respective one of the operating heads is mounted to the handle; wherein the electrical devices for each of said first and said second operating heads comprise electric motors with differing electrical power requirements, and hence power outputs, for operation of a respective one of the operating heads,
wherein the handle has an end coupling part for mechanical connection to each of said first and said second operating heads the end coupling part comprising a cylindrical sleeve portion, wherein said electrical contacts comprises a first electrical contact of the handle being disposed within the sleeve portion and another electrical contact being formed by the sleeve portion, and
wherein the cylindrical sleeve portion forms an annular seal disposed on a peripheral groove positioned axially inwardly.
2. The personal care assembly of claim 1 , wherein the handle comprises a switch for controlling the supply of electric current to the electric device of an operating head mounted to the handle.
3. The personal care assembly of claim 1 wherein the safety razor is a vibrating safety razor.
4. The personal care assembly of claim 3 wherein the electric motor of the first operating head is a coin motor for generating vibrations.
5. The personal care assembly of claim 1 wherein the safety razor comprises a detachable shaving cartridge.
6. The personal care assembly of claim 1 , wherein each of said first and said second operating heads includes a coupling part with a male member slidably engageable in the sleeve portion, and having a radial projection for engagement with a bayonet slot formed in the sleeve portion for releasably locking the male member to the sleeve portion.
7. The personal care assembly of claim 1 , wherein the hair trimmer comprises at least one trimmer blade assembly having a trimmer blade element coupled to be drivable by the electric motor.
8. The personal care assembly of claim 7 , further comprising at least one comb attachment releasably engageable over the hair trimmer for increasing a hair length to which the hair trimmer is operable to trim hairs.
9. The personal care assembly of claim 1 , wherein the hair trimmer comprises a plurality of different trimmer blade assemblies.
10. The personal care assembly of claim 9 , wherein the hair trimmer is movably mounted on a drive unit of the second operating head for positioning a selected one of the blade assemblies at an operative hair trimming position.
11. The personal care assembly of claim 1 , wherein a rechargeable battery is received in the battery compartment of the handle, and the assembly further comprises a charging device for recharging the battery, the charging device having electrical contacts for cooperation with the electrical contacts of the handle when the handle is engaged with the charging device for recharging the battery.
12. The personal care assembly of claim 11 , wherein the charging device is included in a storage holder provided with holding regions for receiving the operating heads during periods of non-use.
13. The personal care assembly of claim 1 , wherein the electric motor of the first operating head is a vibrating electric motor.
14. The personal care assembly of claim 13 , wherein said vibrating electric motor is a coin motor.
15. The personal care assembly of claim 13 , wherein the power output of the electric motor of the second operating head is more powerful than the power output of the vibrating electric motor of the first operating head.
16. The personal care assembly of claim 1 , further comprising at least one comb attachment releasably engageable over the hair trimmer.
