Abstract
A dual ended hair remover which includes a casing having a motor, an epilating head for plucking hairs from the skin of a user attached to one end of the casing, a depilating head for cutting the hairs from the skin of the user attached to the other end of the casing, and a handle which covers one of the epilating and depilating heads while providing power to the other one of the epilating and depilating heads. The handle fits over one or the other end of the casing and provides power to the head which is not covered. The handle may also simultaneously provide power to the head which is covered. The handle protects the user and the unused head by covering the unused head and provides power to at least the head which is in use. Further, by incorporating the epilating and depilating heads on the casing at the same time and at opposite ends, ease of use is obtained. Still further, in the instances that only the head which is in use is being driven, power conservation is achieved.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a dual ended hair remover having depilating and epilating functions for removing hair from a user, and more particularly, to a dual ended hair remover having a casing with a depilating head fixed at one end thereof, an epilating head fixed at the opposite end thereof, and a handle which covers one of the depilating and epilating heads at a time while providing power to drive the other one of the depilating and epilating heads.
2. Description of the Related Art
Shaving devices are known which have multiple heads mounted thereon. The heads may either be permanently affixed to a casing having a motor or may be interchangeable. Such a device may even include a depilating head and an epilating head. A depilating head cuts hairs from the skin of a user, whereas an epilating head plucks (pulls) the hair from the skin of the user.
JP 4-348704, published Dec. 3, 1992 to Iwasaki, discloses a main body in which a motor is contained, an epilating block in which epilating means is contained and a trimmer. Both the epilating block and the trimmer are permanently affixed to one end of the main body, and they both operate simultaneously. The epilating block is at one side and the trimmer is at the other side of the same end, with the depilating block and the trimmer being in close proximity with each other. By being in close proximity with each other, there is a risk of injuring one's self through unintentional contact with the one of the depilating block and trimmer which is not intended to be used at a given time. In addition, as both the depilating block and trimmer operate simultaneously, although one is being used at a given time, unnecessary power is being used to drive the epilating/depilating appliance.
U.S. Pat. No. 3,672,049 issued Jun. 27, 1972 to Demci et al. discloses different operating heads as separate units for individual operation. The operating heads are both trimmers, which are interchangeable with each other at the same end of the casing 11. The two different types of trimmers are mounted one at a time to the casing 11. As a result, effort is required to interchange the two heads to perform the two different types of trimming and extra wearing of the components result from the repeated changing of the heads. Both heads are trimmers, and neither one performs the function of epilation. Also, as only one head is mounted at a time, the unmounted head may easily be lost by the user when not in use.
U.S. Pat. No. 5,611,804 issued Mar. 18, 1997 to Heintke et al. discloses a casing 2 which is adapted to receive a first attachment incorporating an epilating cylinder, or alternatively, a second attachment incorporating a long-hair trimmer. The first and second attachments are interchangeable with each other at a same end of the casing 2. Although Heintke et al. performs both the epilating and depilating functions, the appliance disclosed therein suffers from a number of the same drawbacks as are present in Demci et al. Namely, additional effort is required to replace the epilating head with the depilating head, and vice versa, when alternating between the epilating and depilating functions, and extra wearing of the components result from the repeated changing of the heads. Also, the unattached head may easily be lost by the user when not in use.
Other devices are known which have a shaving head and a long-hair trimmer at a same end of a casing, wherein either the shaver is in operation or both the shaver and the long-hair trimmer are in operation. In these devices, it is often easy to accidentally activate the long-hair trimmer, causing possible injury to the user when such operation is unaccounted for. Further, through the simultaneous operation of both the shaver and the long-hair trimmer, unnecessary power is required to drive both heads. Still further, such devices do not enable the epilation function to be performed.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a dual ended hair remover having both a depilating function and an epilating function.
It is another object of the present invention to provide a dual ended hair remover having a casing and a depilating head and an epilating head fixed at respective opposite ends of the casing.
It is a further object of the present invention to provide a dual ended hair remover having a casing, depilating and epilating heads fixed at respective opposite ends thereof, and a handle which alternately attaches to the opposite ends of the casing so as to cover one of the depilating and epilating heads while providing power to the other one of the depilating and epilating heads.
It is a further object of the present invention to provide a dual ended hair remover having a casing, depilating and epilating heads fixed at respective ends thereof, so as to lengthen the durability of the heads since there is no need to repeatedly detach and reattach the same.
It is still a further object of the present invention to provide a dual ended hair remover having a casing, depilating and epilating heads simultaneously fixed to the casing, and a handle which covers one of the depilating and epilating heads while providing power to the other one of the depilating and epilating heads.
It is still yet further another object of the present invention to provide a dual ended hair remover having a casing, depilating and epilating heads simultaneously fixed to the casing, and a handle which covers one of the depilating and epilating heads while providing power to the other one of the depilating and epilating heads, wherein the casing has a motor for driving the depilating and epilating heads, and a coupling unit to disengage the one of the depilating and epilating heads covered by the handle while engaging the motor and the one of the depilating and epilating heads which is not covered by the handle.
Additional objects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
The above objects of the present invention are achieved by providing a dual ended hair remover to remove hairs from skin of a user, comprising a casing having first and second ends opposite each other, an epilating head mounted on the first end, to pluck the hairs from the skin of the user, and a depilating head mounted on the second end, to cut the hairs from the skin of the user.
The above and other objects are further achieved by providing a dual ended hair remover to remove hairs from skin of a user, comprising a casing having first and second ends opposite each other, an epilating head mounted on the casing, to pluck the hairs from the skin of the user, a depilating head mounted on the casing, to cut the hairs from the skin of the user, and a handle to alternately cover the epilating head and enable driving of the depilating head, and cover the depilating head and enable driving of the epilating head. The above and other objects are still further achieved by providing a dual ended hair remover to remove hairs from skin of a user, comprising a casing having first and second ends opposite each other, an epilating head mounted on the casing, to pluck the hairs from the skin of the user, a depilating head mounted on the casing, to cut the hairs from the skin of the user, and a handle to alternately cover the epilating head and enable driving of the depilating head without enabling driving of the epilating head, and cover the depilating head and enable driving of the epilating head without enabling driving of the depilating head.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Reference will now made in detail to the present preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout.
FIGS. 1A and 1B
are perspective views of a dual ended hair remover in accordance with the first embodiment of the present invention. The dual ended hair remover
10
has a casing
12
, an epilating head attached to one (a first) end of the casing and a depilating head (shaving unit) attached to the other (second) end of the casing
12
. A pair of contacts
18
are exposed at respective opposite sides of the casing
12
, in between the epilating head
14
and the depilating head
16
. An on/off switch
17
extends from a middle of one of the surfaces of the casing
12
to control power to the epilating head
14
and the depilating head
16
.
A handle
20
fits over either of the ends of the casing
12
, selectively covering the epilating head
14
and the depilating head
16
. A pair of terminals
22
are thin strips of metal extending in opposite directions from a power receptacle
24
. The terminals
22
run along opposite sides of inner walls of the handle
20
.
FIG. 1A
shows the handle
20
about to be placed over (attached to) the first end of the casing
12
so as to cover the epilating head
14
, and
FIG. 1B
shows the handle
20
about to be placed over (attached to) the other end of the casing
20
so as to cover the depilating head
16
.
Regardless of whether the handle is placed over the first end or the second end of the casing
12
, the terminals
22
respectively come into contact with the contacts
18
to provide electrical power to the contacts
18
.
FIGS. 2A and 2B
respectively show a plan view and a perspective view of the interior mechanical configuration region of the casing
12
. A motor
26
is positioned near a center of the interior of the casing
12
. First and second axles
30
,
32
extend from opposite sides of the motor
26
, the first axle
30
having an axis pointing toward the epilating head
14
and the second axle
32
having an axis of rotation directed toward the depilating head
16
. When the handle
20
is placed over the epilating head
14
or the depilating head
16
, the terminals
22
respectively come into contact with the contacts
18
, thereby providing power to the contacts
18
. The contacts
18
provide power to the motor
26
(see description of the electrical circuitry below), thereby causing the first and second axles
30
,
32
to rotate.
A rotary gear
34
is affixed to the end of the axle
30
and is concentric thereto. A rotary gear
36
is permanently engaged with the rotary gear
34
, has an axis of rotation parallel to that of the rotary gear
34
, and has teeth
38
extending from the surface of the rotary gear
36
facing away from the motor
26
. A rotary gear
40
is positioned at a right angle to the rotary gears
34
and
36
, and permanently engages the teeth
38
of the rotary gear
36
. A rotary gear
42
is affixed to an end of an axle
44
of the epilating head
14
. Grippers
46
are formed at the periphery of an epilating cylinder
48
of the epilating head
14
.
When the first axle
30
is driven by the motor
26
, the rotary gear
34
is rotated, thereby rotating the rotary gear
36
and the teeth
38
. The rotation of the teeth
38
causes the rotary gear
40
to rotate at a 90° angle relative to the rotary gear
36
, thereby causing the rotary gear
42
to rotate. The rotation of the rotary gear
42
causes the axle
44
of the epilating cylinder
48
to rotate, thereby causing the grippers
46
to open and close, so as to pluck hairs from the skin of a user.
The motor
26
simultaneously drives the second axle
32
, thereby causing a shaving element
50
to reciprocate back and forth relative to a fixed element
52
. The reciprocation of the shaving element
50
relative to the fixed element
52
causes hair extending from the surface of the skin of the user between the shaving element
50
and the fixed element
52
to be cut.
FIGS. 3A and 3B
show a first situation wherein the handle
20
covers the epilating head
14
, and a second situation wherein the handle
20
covers the depilating head
16
, respectively. The contacts
18
are connected to two opposite points of a regulator (a wheatstone bridge)
54
and positive and negative poles
56
,
58
of the motor
26
are connected to other opposite points of the regulator
54
. A transformer
60
which is part of an external adapter (not shown) converts a 230V-110VAC from a wall socket
62
to 3V-18VAC which is transmitted through the power receptacle
24
to the terminals
22
. When the handle
20
is placed over the first end to cover the epilating head
14
or the second end to cover the depilating head
16
, power is supplied through the terminals
22
to the contacts
18
, and subsequently to the motor
26
through the regulator
54
and the positive and negative poles
56
,
58
of the motor
26
.
As a result of this two-contact AC system, the electrical system forms an adapter which converts AC current to DC current inside the casing
12
, so that there is no importance placed on the polarity of the contacts
18
.
FIGS. 4A and 4B
show a perspective view and a plan view of the dual ended hair remover
10
having the two-contact AC system, respectively, shown in
FIGS. 1A through 3B
.
FIG. 4C
shows the electrical contacts
22
respectively in contact with the contacts
18
when the handle
20
(the external portion of the handle
20
not being shown herein) is placed over the first end of the casing
12
to cover the epilating head
14
.
FIG. 4D
shows the terminals
22
in contact with the contacts
18
, respectively, when the handle
20
(the external portion of the handle
20
not being shown herein) is attached over the second end of the casing
12
to cover the depilating head
16
.
FIGS. 5A through 5D
show various views of the internal electrical circuitry for the two contact AC power system shown in
FIGS. 3A through 4D
.
FIG. 5A
shows a front perspective view of the electrical circuitry,
FIG. 5B
shows a back perspective view of the electrical circuitry,
FIG. 5C
shows the terminals
22
of the handle
20
(not shown in this drawing) contacting the respective contacts
18
when the handle
20
is mounted at one end of the casing
12
to cover the epilating head
14
, and
FIG. 5D
shows the terminals
22
in contact with the respective contacts
18
when the handle
20
(not shown in this drawing) is mounted on the other end of the casing
12
to cover the depilating head
16
.
A printed circuit board (PCB)
21
has two diodes
23
and a switch
25
mounted thereon. The PCB
21
receives AC current from the contacts
18
which are supplied from the terminals
22
(see FIGS.
5
C and
5
D).
FIG. 5B
shows wires
27
that conduct the AC current from the contacts
18
from both sides to the rectifier
54
shown in
FIGS. 3A and 3B
, and then the DC direct current is supplied to the positive and negative leads (motor poles)
56
,
58
of the motor
26
.
A variety of other mechanical configurations and electrical circuitries may be adapted for use in the present invention, some of which are explained below.
FIGS. 6A and 6B
show a plan view and a perspective view of the internal mechanical configuration of the casing
12
according to a second embodiment of the present invention. The mechanical elements and operation of the mechanical elements are substantially the same as the internal mechanical elements shown in
FIGS. 2A and 2B
with the following exceptions.
Instead of the second axle
32
extending from the opposite side of the motor
26
to that of the first axle
30
to reciprocatingly drive the shaving element
50
, a second axle
66
is attached to the rotary gear
36
so as to extend parallel to the first axle
30
alongside the motor
26
and past the motor
26
. The end of the second axle
66
opposite the rotary gear
36
is attached to the shaving element
50
. When the motor
26
is driven, the first axle
30
rotates, thereby rotating the rotary gear
36
. As a result of rotation of the rotary gear
34
, the rotary gear
36
rotates, thereby rotating the second axle
66
, to cause the reciprocating movement of the shaving element
50
relative to the fixed element
16
. As a result, hair positioned between the shaving element
50
and the fixed element
52
is cut, as in the first embodiment. The epilating cylinder
48
is driven simultaneously with the shaving element
50
, with either the epilating head
14
or the depilating head
16
being covered by the handle
20
.
FIGS. 7A and 7B
show a plan view and a perspective view of the internal mechanical portion of the casing
12
for driving the epilating head
14
and the depilating head
16
according to a third embodiment of the present invention. In this third embodiment, instead of the motor extending in a lengthwise direction of the casing
12
in a direction from the epilating head
14
to the depilating head
16
, the motor is rotated 90° from that of the first and second embodiments shown in
FIGS. 1A through 5B
. In this third embodiment, the motor
26
extends in a direction from one side of the casing
12
to the other side, and not in a direction from one end to the other. A bracket
78
is fixed within the casing
12
. The motor
26
is mounted in the bracket
78
and is movable between a position A and a position B. The mounting of the handle
20
on the epilating head
14
or the depilating head
16
or a switch in the interior of the handle
12
based upon the mounting of the handle
12
on the epilating head
14
or the depilating head
16
may be used to move the motor between the positions A and B. The first axle
30
extends from one side of the motor
26
and is rotated in conjunction with the driving of the motor
26
. The rotary gear
34
is coaxial with and placed at the end of the first axle
30
.
A rotary gear
38
has an axis of rotation parallel to the axis of rotation of the rotary gear
34
and is positioned at a right angle relative to a rotary gear
70
. A rotary gear
70
has teeth
72
extending from a surface thereof to permanently engage with the rotary gear
68
. The rotary gear
70
is connected to the shaving element
50
. A rotary gear
74
has an axis of rotation parallel to the axis of rotation of rotary gear
34
, and is permanently engaged with a rotary gear
76
. The rotary gear
76
is permanently engaged with the rotary gear
40
.
In the position A (when the handle
20
is mounted over the epilating head
14
), the rotary gear
34
attached to the first axle
30
engages with the rotary gear
68
, and is disengaged from the rotary gear
74
. The rotation of the rotary gear
34
causes the rotary gears
68
to rotate, thereby causing the rotary gear
70
to rotate through the interaction of the teeth
72
with the rotary gear
68
. The rotation of the rotary gear
70
causes the shaving element
50
to move in a reciprocating motion relative to the fixed element
52
of the depilation head
16
.
When the motor
26
is in the position B (when the handle
20
is mounted over the depilating head
16
), the rotary gear
36
engages the rotary gear
74
, and is disengaged from the rotary gear
68
. The rotation of the rotary gear
34
causes the rotation of the rotary gears
74
,
76
,
40
, and
42
, thereby causing rotation of the epilating cylinder
48
. As a result, the grippers
46
open and close to pull the hair, positioned between the grippers, from the skin of the user.
The two contact system shown in
FIGS. 1A
,
1
B and
3
A through
4
B may be used to power the motor
26
.
In the third embodiment, because the motor
26
is movable between the positions A and B, it is possible to selectively drive the epilating head
14
and the depilating head
16
, only when necessary. Therefore, if the epilating head
14
is covered by the handle
20
, only the depilating head
16
need be driven. If the depilating head
16
is covered by the handle
20
, only the epilating head
14
need be driven. Such a configuration saves power by not simultaneously driving both the epilating head
14
and the depilating head
16
while only one head is being used while the other one is covered.
FIGS. 8A and 8B
show a plan view and a perspective view of the internal mechanical configuration and operation of the casing
12
, respectively, according to a fourth embodiment of the present invention. Many of the mechanical parts are very similar to those shown in
FIGS. 6A and 6B
, except there are distinctions to enable selective driving of the epilation head
14
and the depilation head
16
as in the third embodiment shown in
FIGS. 7A and 7B
. Like the second embodiment shown in
FIGS. 6A and 6B
, the rotary gear
34
is currently engaged with the rotary gear
36
. However, instead of the rotary gear
36
having teeth extending from a surface thereof, another rotary gear
80
is adjacent to the rotary gear
36
, but may or may not rotate based upon the rotation of the rotary gear
36
. The rotary gear
80
has teeth extending from a surface thereof in a direction toward the epilating head
14
. Further, the rotary gear
80
has a hole in the middle and protrusions
84
at a periphery of the hole and extending from the same surface as the teeth at 90° intervals. The second axle
66
, unlike in the second embodiment shown in
FIGS. 6A and 6B
, extends beyond the rotary gear
36
and through the hole of the rotary gear
80
. A spline
90
is fixedly formed at the end of the axle
66
and has slots
92
formed at 90° intervals. A coupler
86
having protrusions
88
is selectively moved linearly to either engage the protrusions
84
or the slots
92
of the spline
90
.
FIGS. 9A and 9B
show a more detailed perspective view of the coupler
86
engaging the protrusions
84
of the rotary gear
80
and the slots
92
of the spline
90
, respectively.
FIG. 10
shows a plan view of the rotary gear
34
engaged with the rotary gear
36
, and the rotary gear
80
and the coupler
86
positioned above the rotary gear
36
.
FIGS. 11A and 11B
are cross-sectional views of the coupling unit shown in
FIGS. 9A and 9B
, respectively.
FIG. 12
shows an exploded view of the coupling unit shown in
FIGS. 9A through 11B
.
In
FIGS. 9A and 11A
, the coupler has been moved into a first position so that recesses
94
formed therein to correspond with the protrusions
84
of the rotary gear
80
are engaged by the protrusions
84
. A description of the how the coupling moves between the first and second positions will be described later in the specification.
As shown in
FIG. 12
, the rotary gear
36
has a thickened region
96
extending therefrom and through the hole of the rotary gear
80
. The thickened region
96
is coaxial with the second axle
66
, and has slots
98
formed at 90° relative to each other and extending along the lengthwise direction of the second axle
66
. The protrusions
88
of the coupler
86
are slidable within the slots
98
of the thickened region
96
, and as the rotary gear
36
and the thickened region
96
rotate, the coupler
86
is rotated through the interaction of the protrusions
88
and the slots
98
.
A description of the mechanical operation according to the fourth embodiment when the coupler
86
is in the first position will now be described. As the motor
26
is driven, the axle
30
rotates the rotary gear
34
so that the rotary gear
36
is rotated. The rotation of the rotary gear
36
causes the thickened region
96
to rotate so that the coupler
86
rotates through the interaction between the slots
98
and the protrusions
88
. The interaction between the engagement of the protrusions
84
of the rotary gear
80
and the recesses
94
of the coupler
86
cause the rotary gear
80
to rotate. Because the teeth
82
of the rotary gear
80
are permanently engaged with the rotary gear
40
, the rotary gear
40
is rotated, thereby rotating the rotary gear
42
. As a result, the axle
44
is rotated, to thereby rotate the epilating cylinder
48
, which in turn causes the grippers
46
to rotate and open and close. Based upon the rotation and opening and closing of the grippers
46
, the hairs from the skin of the user are plucked, to accomplish the epilation function.
FIGS. 9B and 11B
show when the coupler
86
is in the second position. At this time, the recesses
94
disengage from the protrusions
84
of the rotary gear
80
, and the protrusions
88
engage with the slots
92
of the spline
90
. When the coupler
86
is in this second position, the protrusions
88
, which extend through the height of the coupler
86
are within both the corresponding slots
98
and the corresponding slots
92
.
When the motor
26
is driven, the first axle
30
rotates the rotary gear
34
, thereby rotating the rotary gear
36
. The thickened region
96
rotates in conjunction with the rotary gear
36
, thereby causing the rotation of the coupler
86
through the interaction of the engagement of the protrusions
88
within the corresponding slots
98
. Simultaneously, the protrusions
88
are at least partially engaged in the corresponding slots
92
of the spline
90
, thereby rotating the second axle
66
. The rotation of the second axle
66
causes the shaving element
50
to move in the reciprocating motion relative to the fixed element
52
, thereby cutting the hairs from the skin of the user which are positioned between the sharing element
50
and the fixed element
52
.
FIGS. 13 through 15
show a coupling mechanism for moving the coupler
86
between the first and second positions.
FIG. 13
shows a fork
100
which is connected at one end to the coupler
86
so that a portion of the fork
100
goes around part of the periphery of the coupler
86
. The other end of the fork
100
is fixed to a lever mechanism
102
which extends perpendicularly from the bottom surface (see
FIG. 12
) of the fork
100
. The lever mechanism
102
includes an H-shaped bracket having a protrusion
107
fixed to an interior portion of the casing
12
so that the H-shaped bracket
109
is rotatable about an axis of the cylindrical protrusion
107
. A cylindrical piece
103
is fixed in between one of the gaps of the H-shaped bracket
109
at one end and to the fork
100
at the other end thereof. A T-shaped arm
105
has one end fixed to the other gap in the H-shaped bracket
109
.
FIG. 14
shows the coupler
86
, the fork
100
and the lever mechanism
102
(which are in the interior part of the casing
12
) which are pushed in one direction by the handle
20
when the handle
20
is mounted on the casing
12
. When the handle
20
is inserted over one end of the casing
12
to cover the epilating head
14
, the T-shaped arm
105
is moved downward (in FIGS.
13
through
15
), the H-shaped bracket
109
is rotated clockwise about the cylindrical protrusion
107
and the cylindrical piece
103
is pushed upward, thereby pushing the fork and coupler upward to the first position to engine the spline
90
. When the handle
20
is removed from the casing
12
and inserted over the other end of the casing
12
to cover the depilation
16
, the T-shaped arm
105
is moved upward, thereby causing the H-shaped bracket
109
to rotate counterclockwise about the cylindrical protrusion
107
. As a result, the cylindrical piece
103
is pulled downward, thereby moving the fork
100
and the coupler
86
downward to the first position. Then, the protrusions
84
of the rotary gear
80
engage the recesses
94
of the coupler
86
. A more detailed view of the interaction between the lever mechanism
102
and the fork
100
is shown in FIG.
15
. The handle
20
contacts the lever mechanism
102
through a track in the casing
12
. When the handle
20
is inserted over one end of the casing
12
to cover the epilating head
14
, the lever mechanism
102
pushes against the fork
100
to move the coupler
86
to the second position. When the handle
20
is removed from the casing
12
and inserted over the other end of the casing
12
to cover the depilation head
16
, the lever mechanism
102
pushes on the opposite side of the fork
100
to move the coupler
86
. A more detailed view of the interaction between the lever mechanism
102
and the fork
100
is shown in FIG.
15
.
Based upon the positioning of the handle
20
, the lever mechanism
102
pushes or pulls the fork
100
to selectively move the coupler
86
to the first and second positions, thereby selectively driving the one of the epilating head
14
and the depilating head
16
which is positioned at the opposite end of the casing
12
from which the handle
20
is mounted. Therefore, when the handle
20
covers the epilating head
14
, the depilating head
16
is driven by the coupler
86
being positioned at the second position, whereas when the handle
20
covers the depilating head
16
, the epilating head
14
is driven by the movement by the coupler
86
to the first position.
Another possible coupling mechanism for moving the coupler
86
between the first and second positions to alternately engage the epilating head
14
and the depilating head
16
is shown in
FIG. 16
according to another aspect of the fourth embodiment of the present invention. A spring
104
biases the lever mechanism
102
so that the fork
100
is in either the first or second position, and as shown in the drawing, biases the lever mechanism
102
so that the fork
100
is in the second position so that the protrusions
88
engage the slots
92
of the spline
90
. When the handle
20
is mounted on the depilating head
16
, the handle
20
moves the lever mechanism
102
to push down on the fork
100
, thereby moving the coupler
86
to the first position against the bias of the spring
104
. As a result, the coupler
86
disengages from the spline
90
and the recesses
94
of the coupler
86
are engaged by the protrusions
84
of the rotary gear
80
. When the handle
20
is removed from the depilating head
16
, the coupler
86
is moved back to the second position through the bias of the spring
104
.
Based upon the two aspects described above regarding the movement of the coupler
86
between the first and second positions, it is possible to alternately engage the epilating head
14
and the depilating head
16
, so that only one head is operating at a given time. As are result, power is conserved, and wear and tear on the epilating and depilating heads
14
,
16
are minimized.
Of course, one of ordinary skill in the art would recognize that there are any number of different ways to move the coupler
86
between the first and second positions to selectively engage the splines
90
and the protrusions
84
of the rotary gear
80
.
FIGS. 17A through 19C
show another electrical system for supplying power to the motor
26
using a three-contact AC system according to a fifth embodiment of the present invention. In the three-contact AC system, the transfer of current is performed by an adapter within a casing
112
, wherein there are three contacts instead of two.
FIGS. 17A and 17B
show the internal schematic drawings of the power electrical system of the dual ended hair remover when the handle
20
is attached to one end of the casing
112
which covers the epilating head
14
and when the handle is connected to the other end of the casing
112
to cover the depilating head
16
. As shown in
FIGS. 18A through 18C
, the casing
112
differs from the casing
12
in that there are three contacts
114
,
116
and
118
which are exposed externally from the casing
112
. The handle
20
, instead of having terminals
22
extending along the inner peripheries of opposite sides of the handle
20
, has terminals
122
,
124
extending along an inner surface of the back of the handle
20
.
The central contact
116
has a positive polarity, while the outside contacts
114
,
118
have a negative polarity and are connected together. The central contact
116
is connected to one end of the rectifier
54
, whereas the outside contacts
114
and
118
are connected to the other end of the rectifier
54
.
As shown in
FIGS. 17A and 18B
, when the handle
20
is attached at one end of the casing
112
to cover the epilating head
14
, the terminal
124
contacts the center contact
116
and the terminal
122
contacts the outer contact
114
. As shown in
FIGS. 17B
,
18
C and
19
B, when the handle
20
is attached to the other end of the casing
112
so as to cover the depilating head
16
, the terminal
124
contacts the center contact
116
and the terminal
122
contacts the outer lead
118
.
FIG. 19C
shows a closeup of
FIG. 19B
, and shows a conductor
126
of the motor
26
having a minus polarity, a conductor
128
having a positive polarity, and a conductor
130
of the motor
26
having a negative polarity. A wire
132
connects the conductors
126
,
130
to the negative terminal
58
of the motor
26
. A wire
134
connects the conductor
128
with a switch
136
. A wire
138
connects the switch
136
to the positive lead
56
of the motor.
Regardless of at which end of the casing
12
the handle
20
attaches, the terminal
124
contacts the positive conductor
128
, and the terminal
122
contacts either of the negative conductors
126
,
130
.
Although
FIGS. 19A through 19C
show a mechanical configuration similar to that shown in
FIGS. 7A and 7B
, other mechanical configurations such as those shown in
FIGS. 2A and 2B
, and
6
A and
6
B may be used with the three-contact AC power systems.
FIGS. 20A through 21C
show a four-contact AC power electrical system according to a sixth embodiment of the present invention. The casing
212
as shown in
FIGS. 21A through 21C
differs from casings
12
,
112
in that there are four contacts
214
,
216
,
218
,
220
which are externally exposed from the casing
212
. The terminals
122
,
124
of the handle
20
contact either the contacts
214
,
216
or contacts
218
,
220
, depending upon which end of the casing
212
at which the handle
20
attaches.
FIGS. 20A and 20B
show that there are two separate contact systems which are combined within the casing
212
. The rectifier
54
provides DC power from the terminals
122
,
124
to the contacts
214
,
216
or the contacts
218
,
220
. The rectifier
54
is in an outside adapter (not shown) external to the dual ended hair remover
10
.
As one can see, there are numerous power electrical circuits which may drive the motor to operate the epilating head
14
and the depilating head
16
. The three-contact or four-contact AC system according to the fifth and sixth embodiments may be used in any of the first through fourth embodiments. One of ordinary skill in the art would recognize that there may be other power electrical systems which would properly operate the motor
26
.
FIGS. 22A and 22B
show a plan view and a perspective view of internal mechanical configuration for the casing
12
according to a seventh embodiment of the present invention. In the seventh embodiment, there is a second motor
226
in addition to the first motor
26
. The configuration of the rotary gears
34
,
74
,
76
,
40
and
42
in relation to powering the epilating head
14
is the same as that shown in
FIGS. 6A and 6B
, with the exception that the motor
26
is not movable within the casing
12
. Thus, the motor
26
is used only to drive the epilating head
14
, and not the depilating head
16
.
The second motor
226
is positioned perpendicular to the motor
26
, and has an axle
228
which is connected to the moving element
50
of the depilating head
16
so as to move the moving element
50
in a reciprocating motion relative to the fixed element
52
, as in the other embodiments of the invention.
FIGS. 23A and 23B
are schematic electrical diagrams of the power electrical circuitry for driving the motors
26
,
226
.
FIG. 24
shows the internal mechanical configuration of the casing
212
which has the contacts
214
,
216
,
218
,
220
as in the sixth embodiment. The difference is that the contact
214
is connected to the negative pole
56
of the motor
26
and the contact
216
is connected to the switch
136
. The contact
218
is connected to the negative pole
56
of the motor
226
and the contact
220
is connected to the switch
136
. The positive and negative poles of the second motor
226
are
256
,
258
, respectively. The rectifier
54
is part of an outside adapter external to the dual ended hair remover
10
.
