  • this massage device includes advantageously a propeller mounted on the output shaft of the motor, upstream of the worm, the housing being drilled, around the periphery of the orifice housing the motor shaft, of lights for the passage of the air circulated by said propeller.
  • Such a propeller has a double function: on the one hand, it cools the engine, and on the other hand, it provides a flow of air heated by said motor whose action is not only physiological, but also mechanical because leading to the dispersion of materials raised during contact with massage devices on the skin.
  • the massage device shown in Figures 1 and 2 show the essential feature of have a floating massage head.
  • This massage device is presented under the shape of a case 1 made up of two half-cases 2, 3 forming an ergonomic handle for handling with one hand.
  • This case 1 also constitutes a housing housing the various elements (electric motors, ...), and whose interior layout is adapted to ensure the maintenance of each of said elements.
  • this case has, on the underside of the casing, of a cylindrical wall 4 arranged to extend around the massage head, on a partial portion of the height of the latter.
  • the massage device includes, first instead, a DC motor 5 housed in the housing 1.
  • This motor 5 is electrically powered via an electronic card 6 connected to a cable electric 7 intended to be connected to the network.
  • This cable 7 enters the box 1 through a orifice 8 formed in this housing and is blocked, in view to avoid any risk of disconnection, by a system of baffle 9.
  • the electronic card 6 is, moreover, connected to a switch 10, said card and switch being adapted to allow two speeds to be selected motor rotation 5.
  • the massager further comprises associated with motor 5, a reduction unit consisting of a screw endless 11 extending in the extension of the shaft of outlet 5a of said motor, and of a toothed wheel 12 meshing with said worm.
  • the massage device includes, also associated with motor 5, a propeller 13 mounted on the output shaft 5a of said motor upstream of the screw without end 11.
  • This propeller 13 is adapted to create a flow air capable of cooling the motor 5, and to deliver the flow of heated air to the head of massage, via lights, such as 14, formed in the half-housing 3 so as to communication inside the box 1 and the volume delimited by the cylindrical wall 4.
  • the housing 1 comprises, to the right of the propeller 13, a transverse internal wall 1a separating the interior of said housing in two upstream compartments and downstream relative to said propeller.
  • the massage device also has a drive shaft 15 for transmission to the massage head, rotational movement of the motor / gear unit.
  • this motor shaft 15 has knurling and is force-fitted to the interior of a blind bore 12a formed axially in the soul of the toothed wheel 12.
  • This drive shaft 15 extends outside of the housing 1 through an orifice formed in this last, axially relative to the cylindrical wall 4.
  • the wall of the housing 1 is shaped, at this orifice, so as to constitute a sleeve 16 to the interior of which is housed a bearing 17.
  • the opposite, lower, end of the tree motor 15 consists of a threaded section 15b, of diameter lower than that of the upper section 15a, on which comes to screw a shaft end 18 arranged to extend in the lower extension of said drive shaft 15, and whose ability to be dismantled is intended to allow the installation of elastic support members described below.
  • This shaft end 18 splits longitudinally in three sections, namely, referring to Figure 3: a cylindrical upper section 18a of section substantially smaller than that of the section upper 15a of the motor shaft 15, a section intermediate 18c consisting of an annular groove of semi-cylindrical section separated from the upper section 18a by a shoulder 18b, and a lower section 18d, of very much longer than the other two sections, having a hexagonal section.
  • this lower section 18d includes, at a short distance from its lower end, an annular groove housing an O-ring 19 of thickness adapted to partially protrude outside of this throat.
  • the elastic support bodies mentioned more top consist of two O-rings 20, 21 intended for allow respectively axial and angle of the massage head.
  • the first 20 of these O-rings constituting the elastic axial support member, is arranged around the upper section 18a of the shaft end, and is held between two washers 22, 23, one of said washers 22 being pinched between the motor shaft 15 and the shaft end 18, and the other washer 23 resting on the shoulder 18b of said shaft end.
  • the second 21 of these O-rings constituting the elastic radial support member, is housed in the annular groove formed by the intermediate section 18c of the shaft end 18, and has a thickness adapted to partially protrude outside of this throat.
  • two anti-friction washers 24, 25 are arranged around the drive shaft 15, in upper and lower contact with the bearing 17.
  • Massage heads designed to equip a such massage device are all composed of a hub central 26 in which is formed a bore 27 of section hexagonal, suitable for allowing the mounting of said heads massage, and arms such as 28, in the example of three, uniformly distributed, extending radially by relative to the axis of the bore 27, each of said arms being consisting of a rod carrying at least one massage member.
  • the bore of the hub 26 also has longitudinally, the shape of two opposite diverging lines 27a, 27c separated by a neck 27b of cross section combined with that of the lower hexagonal portion 18d of the shaft end 18, each of said diverging having a section increasing towards one end of bore 27.
  • this bore 27 comprises a counterbore 29 at its upper end, capable of housing the portion of the O-ring 20 projecting radially at the outside of the annular groove constituting the section intermediate 18c of the shaft end 18.
  • central hub 26 has, at counterbore level 29, an upper shaped section annular of dimensions adapted so that said hub come into high abutment against the washer 23 once the massage head in place.
  • Such a massage device is therefore designed to allow rapid assembly and disassembly of the heads massage by simple snap, the stop member ensuring the maintenance of these massage heads being consisting of the O-ring 19 whose external dimensions, excluding stresses, are greater than those of the collar 27b.
  • the massage heads may suffer, on the one hand, an axial movement by compression of the seal toric 20, and on the other hand, an angular displacement by compression of the O-ring 21, this angular movement being further authorized by the divergent form of bore 27.
