Abstract

A device (1) for the treatment of a region of a body comprises the following components, i.e.: a housing (2) which can be held in one hand, a tool (10) provided for treating the region of the body, drive means (14) for driving the tool (10), and compression force definition means (65) for defining a desired compression force obtaining between the tool (10) and the region of a body under treatment, as well as adjustment means (66) accommodated in the housing (2) for adjusting the range for a desired compression force.

Claims

1. A device (1) for the treatment of a region of a body, which device (1) comprises means as listed below, i.e.:

a housing (2) which can be held in one hand, and

a tool (10) provided for the treatment of the region of the body, and

drive means (14) which are accommodated in the housing (2), which are adjustably supported with respect to the housing (2), which are constructed for driving the tool (10), and to which the tool (10) is coupled, and

compression force definition means (65) by means of which a region for a desired compression force can be defined with which the tool (10) can act on the region of the body,

and which comprise at least one region (78, 79) in engagement with the drive means (14) and

at least one region (73) in engagement with a support part (66), and

adjustment means (66) provided in the housing (2) and constructed for adjusting the range for a desired compression force.

2. A device (1) as claimed in claim 1, wherein the adjustment means (66) are formed by said support part (6) which is adjustable relative to the housing (2) by means of a manual control member (67).

3. A device (1) as claimed in claim 2, wherein the adjustable support part (66) comprises an adjustment cam (68) which has a changing height gradient with respect to the region (73) of the compression force definition means (65) bearing on the support part (66).

4. A device (1) as claimed in claim 3, wherein the adjustable support part (66) is formed by a rotatably supported disc (66) which is provided in the interior of the housing (2), and wherein a rotary knob (67) serving as the manual control member (67) is connected to said disc (66).

5. A device (1) as claimed in claim 4, wherein the rotary knob (67) has an extension (69) which is passed through a hole (70) in the housing (2) and which is connected to the disc (66).

6. A device (1) as claimed in claim 1, wherein the compression force definition means (65) are formed by spring means (65).

7. A device (1) as claimed in claim 6, wherein the spring means (65) are realized in the form of a wire spring (65).

8. A device (1) as claimed in claim 7, wherein the wire spring (65) comprises a central portion (73) bent into a U-shape with two spring legs (74, 75) for cooperation with the support part (66), and comprises two spiraling spring portions (76, 77) each extending away from one of the two spring legs (74, 75) and provided for journaling of the wire spring (65), and comprises two load legs (78, 79) which each extend from one of the two spiraling spring portions (76, 77) and which bear on the drive means (14).

9. A device (1) as claimed in claim 1, wherein the drive means (14) are accommodated in retention means (28) which are pivotably journaled about a pivot rod (29) passed through the retention means (28).

10. A device (1) as claimed in claim 3, wherein the retention means (28) comprise a first holder region (32) for the accommodation of a motor (15) of the drive means (14), which region lies substantially at the side remote from the tool (10) with respect to the pivot rod (29), and wherein the retention means (28) comprise a second holder region (33) for the accommodation of part of a transmission (16) provided between the motor (15) and the tool (10), which region lies at the side facing the tool (10) with respect to the pivot rod (29).

11. A device (1) as claimed in claim 8, wherein the wire spring (65) is journaled with its two spiraling spring portions (76, 77) on the pivot rod (29).

12. A device (1) as claimed in claim 11, wherein the wire spring (65) bears with its load legs (78, 79) on respective leg receptacles (82, 83) provided at the first holder region (32) of the retention means (28).

13. A device (1) as claimed in claim 1, wherein the device (1) is constructed as a facial treatment device (1) with a brush (10) which can be driven into rotation acting as the tool (10).
