DESCRIPTION OF THE PREFERRED EMBODIMENT
In order that our invention may be the more completely understood,
we give hereinafter the preferred form of the present invention by
referring to the accompanying drawing which, however, is not
intended to limit the scope of the present invention in any
way.
In FIGS. 1 and 2, the numeral 1 designates a lower longitudinal
casing which has a slender cylindrical form for ease of gripping
onto which is fitted an upper casing 2 having a shape similar to a
beer-barrel slanting upwardly on the right and left at small angles
with the lower casing 1. The lower longitudinal casing 1
incorporates an electric motor 3 which is activated, for instance,
by power supply available at home, and a reduction gear device 6
consisting of plurality of smaller and larger gears which are
interposed by upper and lower support plates 4, 5 of the motor 3.
To a support member 7 which is positioned almost at the center of
the upper casing 2, there is supported by longitudinal sleeves 8, 9
a longitudinal crank shaft 10, a shaft 11 from the reduction gear
device 6 being connected to one end of said crank shaft 10 and a
bevel gear 12 being connected to the other end thereof.
At the left edge section 2a of the upper casing 2, a stage section
13 defines a concave wall 14. To said stage section 13 is turnably
fitted a shaft 16 equipped with another bevel gear 15 by means of a
sleeve 17, said bevel gear 15 being capable of engagement with the
abovementioned bevel gear 12. A massaging member 19 is pivoted to
this shaft 16 via a universal joint 18 so that it can effect
oscillating motion inside the concave 14. The massaging member 19
has a friction plate 20 made of a resilient material such as a soft
rubber or the like and a rotary disc 21 to support said friction
plate 20. The rotary disc 21 is secured to the universal joint 18
by a nut in a direction opposite an rotation thereof in the
arrangement such that prevents it from jumping out of the massaging
member 19 and can easily be detachable when the universal joint 18
is locked by the reduction gear device 6 at the time when the motor
3 is not in motion.
The massaging member 19 is available in an assortments of surface
plate shapes 20a for the friction plate 20 depending on the kind of
massaging actions desired. FIG. 4 illustrates four types of the
massaging members as examples. FIG. 4 (a) shows the massaging
member having corrugated arc 22 disposed radially on the surface
whose function it is to retain an oily membrane of a vanishing
cream without spreading outwardly when the cream is rubbed into the
skin. The member 19 in FIG. 4 (b) has a swirly corrugated surface
23 which is suited for spreading the skin and smoothing wrinkles,
and the one in FIG. 4 (c) has a surface provided with a number of
small protrusions which is effective for stimulating the skin and
quickening of the blood. Further the massaging member in FIG. 4 (d)
has the friction plate whose surface 20a incorporates a plurality
of rollers 25 disposed radially, and the massaging member having
this shape supplies a good massaging effect when vanishing cream is
not rubbed into the skin.
The upper casing 2 having the abovementioned massaging member 19
further has a hemi-spherical sheet cover 26 at the left edge
section 2A thereof, said sheet cover being fitted to a lock ring 27
and a protrusion 28 of the left edge section 2a. This sheet cover
26 presses a sheet 29 made of a thin membrane of polyethylene,
rubber and the like to the friction plate 20, and detachably covers
the same. When this sheet cover 26 is used, the friction plate 20
does not touch the facial skin directly, it prevents the hardening
and aching of the skin and imparts a deep massaging effect into the
dermis.
On the other hand, at the right edge section 2b of the upper casing
2, there is bored a stepped hole 30 having a relatively large
diameter into which is inserted a stepped cylinder 31 extending
horizontally from the proximity of the support member 7 up to the
outside of the upper casing 2. Inside the larger diameter portion
31a of the stepped cylinder 31, a piston 32 is fitted so as to
reciprocate therein by the engagement of a crank pin 33 of the
crank shaft 10 with a rod 34 and a connector 34'. A thin rubber
member 36 is fitted to the outer periphery of the piston 32 by a
locking element 35. During the forward stroke of the piston 32, the
rubber member 36 is compressed so as to thereby escape the
pressure, and during the return stroke, it expands so as to touch
tightly with the cylinder 31 and thereby generate suction. At the
distal end of the smaller diameter portion 31b of the cylinder,
there is fitted a cap 38 having a suction hole 37 which cap 38 is
further covered by a cover detachably which has an annular concave
chamber 39 inside the suction hole 37. Both of the smaller diameter
portion 31b and the larger diameter portion 31a of the cylinder 31
are respectively provided with suction regulation valves 50 and
relief valves 60.
Said suction regulation valve 50 comprises a small pore 51 which
passes through the smaller diameter portion 31 of the cylinder 31,
a ring 52 which is disposed rotatably in between the edge section
2b of the upper casing 2, the smaller diameter portion 31b of the
cylinder and the cap 38 and a slit 53 fitted at a position to
oppose the small pore 51 of the ring 52 in such a manner as to
continuously vary the degree of opening of the small pore 51 in
accordance with rotational angle of the ring 52. By this
arrangement, the suction regulation valve 50 regulates the force of
suction inside the cylinder by means of escaping a part of the
force of suction 2b of the upper casing to the outside of the
casing.
The relief valve 60 comprises the hole 61 passing through the
larger diameter portion 31a of the cylinder and the upper casing 2,
a cylindrical member 62 fitted into said hole 61, an adjusting
screw 64 equipped with an air inlet 63 and screwed to said
cylindrical member 62, a ball 65 disposed inside the inner plane
64b of the adjusting screw 64 so as to open or close the air inlet
63 by means of suction inside the cylinder, and a spring 66
interposed by a protruding section 62a of the cylindrical member 62
to the side of the cylinder and the ball 65. When the vacuum inside
the cylinder becomes abnormally high, the relief valve 60 sucks the
ball 65 against the spring 66, whereby the air inlet 63 is opened
to introduce open air and lower the vacuum eventually.
In the operation of the facial treatment device of the present
invention, any of the messaging members 19 suited for a desired
message application massage is first fitted to the universal joint
18, and the motor 3 is switched on, whereupon the massaging member
19 initiates rotation at a predetermined speed by the reduction
gear device via the crank shaft 10, bevel gears 12, 15, universal
joint 18 and the like, and at the same time, the piston 32 starts
reciprocation by the action of the crank shaft 10 so as to thereby
generate suction. As the lower casing 1 is being gripped, the
friction plate 20 of the massaging member 19 is gently pressed onto
the face with or without vanishing cream either directly as it is
or as it is attached by the sheet cover 26 in view of the condition
of the skin of the face, and then is moved around. Subsequently
massage is applied to the skin of the face by the rotation of the
friction plate 20; when the skin is rubbed with a vanishing cream,
impurities are extracted from pores of the roots of hair, of the
sweat glands, etc., and when, on the contrary, the skin is not
rubbed with the cream, wrinkles of the skin are smoothed and the
flow of the blood is quickened.
Next, while adjusting the suction by the suction regulation valve
50, the cap 38 is equipped with the cover 40 opposite the massaging
member 19 is applied to the face. Then, suction is caused inside
the cylinder which suctions such dirt and impurities as cream waste
rubbed to the skin and spoiled by the preceeding massaging process,
dirt extracted thereby, face powder, fat and the like. As soon as
these impurities leave the skin, they are mostly collected into the
concave chamber 39 of the cover 40. The impurities thus collected
in the concave chamber 39 can be wiped off by a cloth or the like,
or alternatively be washed off by removing the cover 40 from the
cap 38.
Thus in accordance with the present invention, it is possible to
enhance the vital powers of the facial skin and remove impurities
therefrom by suction and massaging mechanically by simply applying
either the massaging member 19 or the cap 38 to the facial skin.
The device of this invention eliminates troublesome practice of
massaging which heretofore has been done manually, and also
provides an easy and simple removal of impurities by means of
suction.
Further, the facial treatment device of this invention is compactly
designed for ease of operation and good appearance. Being of
slender cylindrical shape, the lower casing is easy to grip, and
the upper casing integrates the means for applying massage for
convenience. A wide variety of attachments which serve as the
friction plate 20 of the massaging member 19 ensures a versatile
application of the massage desired. In addition, indirect massage
is also possible by the use of the cover 26 to be attached to the
massaging member 19 in order to prevent damages of the skin as well
as to facilitate the massage deep into the dermis. The cover 40
collects impurities almost entirely that are extracted by suction
so as not to hinder the reciprocation of the piston 32, and the
suction regulation valve 50 together with the relief valve 60
always ensure an optimum suction.
While certain representative embodiments and details have been
shown for the purpose of illustrating the present invention, it
will be apparent to those skilled in the art that various changes
and modifications may be made therein without departing from the
spirit or scope of the invention.
