FIELD OF THE INVENTION
[0001] The present invention is concerned with body grooming devices that have a head section
and a hand piece section that can be detachably connected. The present invention in
particular is concerned with body grooming devices according to the previous sentence
wherein the head section comprises a drivable body grooming unit and the hand piece
section comprises a drive.
BACKGROUND OF THE INVENTION
[0002] It is known to add further functions to a body grooming device. E.g. European patent
application
08005323.4 describes an epilator device that further comprises a vaporizer for applying vaporized
liquid onto the skin during operation of the epilator device.
SUMMARY OF THE INVENTION
[0003] It is desirable to improve known body grooming devices and in particular to provide
a body grooming device that adds additional comfort to the user or additional functionality
in an improved manner.
[0004] An improved body grooming device is given in accordance with claim 1.
[0005] The proposed body grooming device comprises a head section and a hand piece section.
The head section comprises a drivable body grooming unit, e.g. an epilation unit,
a shaving unit or a massaging unit etc. and the hand piece section comprises a drive,
e.g. a DC motor or a linear motor. Additionally, the body grooming device comprises
an attachment section that in an attached state is detachably arranged between the
head section and the hand piece section. The attachment section comprises a power
transmission unit for transmitting power from the hand piece section to the head section,
so that power generated by the drive is passed through to drive the drivable body
grooming unit in an operation mode with the necessary power (power in the present
context means mechanically provided power). The power transmission unit thus effectively
couples the drive disposed in the hand piece with the drivable body grooming unit.
According to an embodiment, the attachment section has an attachment section coupling
that couples to a hand piece power output of the hand piece section and an attachment
section power output that couples to a head section coupling of the head section.
During operation, the power provided through the hand piece power output is transmitted
by the power transmission unit through the attachment section and provided via the
head section coupling to the drivable body grooming unit.
[0006] Such an attachment section can e.g. be used to individualize the body grooming device
by e.g. adding length to the device when the attachment section is mounted between
the head section and the hand piece section. Users having larger hands than others
may find it more convenient to use the body grooming device with the mounted attachment
section. Instead of extending the body grooming device, the attachment section may
also provide for an angle between the head section and the hand piece section that
is not present if the head section is directly mounted to the hand piece section.
Some users may find it more convenient if the hand piece section is arranged at a
certain angle with respect to the head section. An attachment section as described
can provide for such an arrangement. Different attachment sections may differ in their
geometrical parameters, e.g. two different attachment sections may differently extend
the length of the body grooming device or may lead to different angles between the
head section and the hand piece section. Different attachment sections may hence be
used by different users to individualize the body grooming device according to their
wishes. The attachment section coupling and the attachment section power output are
part of the power transmission unit. The attachment section coupling and the attachment
section power output may be movably supported in the attachment section and they may
be connected by a simple shaft so that the power provided at the attachment section
coupling is transmitted to the attachment section power output via the shaft. In a
realization, the attachment section coupling may comprise a cavity to receive the
hand piece section power output in a form-fit manner so that e.g. a rotation of the
hand piece power output is transmitted to the attachment section coupling. In a refinement,
the power transmission unit comprises a gear section to e.g. realize a change in the
direction of the shaft axis or a lateral shift of the shaft axis or a change in the
frequency of a rotary motion provided at the attachment section coupling.
[0007] A "body grooming device" is a device out of the class of devices that are used to
treat the body, specifically the skin, by hair removal through plucking, shaving or
sheering, by massaging (e.g. to stimulate blood circulation, remove muscle tension
or to treat cellulites), peeling or abrading, by rubbing in an application material
such as a nurturing lotion etc. The drivable body grooming unit may comprise a combination
of two or more sub-units for performing two or more of the mentioned grooming treatments.
[0008] In another embodiment, the attachment section comprises a second attachment section
coupling that mates in the attached state with a second hand piece section power output.
In such an embodiment, the power transmission unit transmits power from the drive
in the hand piece section to the drivable body grooming unit in the head section and
the second attachment section coupling and second hand piece power output arrangement
can be used to transfer power from the drive in the hand piece section to a powered
unit in the attachment section.
[0009] In another embodiment of the proposed body grooming device, the attachment section
comprises a powered unit. The powered unit may e.g. be an ultrasonic vaporizer that
is powered with energy. The energy source may then be comprised in the hand piece
section (where this should include cases in which an energy source such as a battery
or an accumulator is present in the hand piece section and cases where the hand piece
section is connected to mains voltage) or in the attachment section. In an embodiment,
the hand piece section is equipped with a hand piece energy contact structure and
the attachment section with an attachment section energy contact structure. The hand
piece energy contact structure may comprise electrical contacts that connect in an
assembled state with electrical contacts of the attachment section energy contact
structure so that energy can be transferred from the energy source to the powered
unit in a wired manner. In another realization, the energy is transferred in a wireless
manner, e.g. inductively, in which case the hand piece energy contact structure may
comprise a primary coil for generation of electromagnetic radiation and the attachment
section energy contact structure may comprise a secondary coil for receiving the energy
from the electromagnetic radiation. Alternatively, the powered unit may be mechanically
drivable, e.g. the powered unit may comprise a fan or a pump. The drive for driving
such a powered unit may be present in the hand piece or in the attachment section.
In the first case, the attachment section may have a second attachment section coupling
to connect with a second hand piece power output of the hand piece. Alternatively,
power may be extracted from the power transmission unit by a power extraction unit,
which can be realized, e.g., as a gear wheel arrangement. In such an embodiment with
a powered unit present in the attachment section, the attachment section can add a
function to the body grooming device without the need to amend the hand piece section
and/or the head section. Different attachment sections could then provide different
functions. Such a modular approach makes the body grooming device very versatile.
[0010] In another embodiment, the attachment section of the proposed body grooming device
comprises a container. A container can be used to store a liquid, a lotion, or a gel.
The container may be coupled to a liquid supply that is arranged to contact the skin
during operation of the body grooming device. In particular, the liquid supply can
be arranged to transport liquid from the container to the skin due to capillary forces.
[0011] In a further embodiment, the attachment section comprises a first attachment section
connector structure that detachably couples in the attached state with a hand piece
connector structure and a second attachment section connector structure that detachably
couples in the attached state with a head section connector structure. In this embodiment,
the three parts of the body grooming device can be detachably connected by using the
additional connector structures. In a refinement of this embodiment, the hand piece
section connector structure is arranged to detachably connect also with the head section
connector structure. Hence, the head section and the hand piece section can also be
connected together without the attachment section attached in between. In such a case,
the head section power output is also arranged to mate with the head section coupling.
[0012] The invention is also concerned with an attachment section as described that can
be detachably coupled between a head section and a hand piece section so that a body
grooming device is formed. The attachment section comprises a power transmission unit
for transferring power from the hand piece section to the head section. A drivable
body grooming unit present in the head section can thus be driven by a drive present
in the hand piece section. Such an attachment section may be sold as an accessory
for a two-part body grooming device that has only a head section and a hand piece
section so that customers can add functionality to the two-part body grooming device
according to their individual wishes or a customer can geometrically adapt the two-part
body grooming device according to individual wishes by using such an attachment section.
[0013] The invention is further concerned with a kit comprising a head section comprising
a drivable body grooming unit, a hand piece section comprising a drive, and a first
attachment section comprising a power transmission unit, where the first attachment
section is arranged to become detachably attached between the head section and the
hand piece section to form a body grooming device such that in operation the power
transmission unit transmits power from the hand piece section to the head section.
Hence, the power transmission unit passes through the power generated by the drive
so that the drivable body grooming unit can be driven in an operation state of the
body grooming device.
[0014] In an embodiment, the kit further comprises a second attachment section that differs
from the first attachment section in at least a geometrical parameter or a function
provided by the second attachment section. The geometrical parameter can in particular
be the different length of the first attachment section and the second attachment
section or the different angle between head section and hand piece section introduced
by the first attachment section or the second attachment section. The attachment sections
may geometrically coincide but differ in a function. E.g. the first attachment section
may serve no other function than to provide an extension of the hand piece section,
while the second attachment section may have an atomizer unit for applying a mist
of atomized liquid onto the skin during operation.

DETAILED DESCRIPTION OF THE INVENTION
[0016] Fig. 1 is a perspective view onto an exemplary embodiment of a body grooming device
1 as proposed. The body grooming device 1 is shown in an assembled state. The body
grooming device 1 is realized as an epilator device. The body grooming device 1 comprises
a head section 200, an attachment section 100, and a hand piece section 300. The attachment
section 100 is detachably connected in between the head section 200 and the hand piece
section 300. The head section 200 comprises a drivable body grooming unit 230, which
in the shown embodiment is realized as an epilation cylinder for plucking hairs from
the skin during operation. In another embodiment, the body grooming device 1 may be
realized as an electric shaver and the drivable body grooming unit 230 as a foil shaver
head.
[0017] Fig. 2 is a perspective view onto the body grooming device 1 as shown in Fig. 1 but
with the three sections shown in a detached state (exploded view of the three sections).
The hand piece section 300 comprises a hand piece section power output 311, which
is realized as a hexagon shaft. The hand piece power output 311 is connected with
a drive shaft of a drive that is disposed within the hand piece 300 (reference is
made to Figs. 4 - 6 and the respective description concerning the drive shaft and
the drive). The hand piece section 300 further comprises a hand piece connector structure
320. The attachment section 100 comprises on a side that is intended for coupling
with the hand piece section 300 an attachment section coupling 110, which in the shown
embodiment is realized as a shaft having a hexagon recess. The attachment section
100 further has on the side intended for coupling with the hand piece section 300
a first attachment section connector structure 120a. The attachment section comprises
and the side intended for coupling with the head section 200 an attachment section
power output 111 that is realized as a hexagon shaft. The attachment section coupling
110 and the attachment section power output 111 are parts of a power transmission
unit to transfer power provided by the hand piece section 300 to the head section
200. In certain embodiments, the attachment section coupling 110 and the attachment
section power output 111 are connected by a simple drive shaft or a gear arrangement
(this is discussed in more detail with reference to Figs. 4 - 6). Independent on whether
the attachment section simply provides for a geometrical adaption of the body grooming
device (see Figs. 7A - 7D) or adds a function (see Fig. 3), the attachment section
100 provides for the transmission of power from the hand piece section 300 to the
head section 200. The attachment section 100 further comprises on the side intended
for coupling with the head section 200 a second attachment section connector structure
120b. The head section 200 comprises a head section coupling 210 that is realized
as a shaft having a hexagon recess. The head section 200 further comprises a head
section connector structure 220.
[0018] The hand piece section power output 311 is arranged to mate with the attachment section
coupling 110 in the attached state. In the shown embodiment, the hexagon shaft then
sits in the respective form-fit hexagon recess provided in the shaft of the attachment
section coupling 110. In another embodiment, the hand piece power output 311 is realized
as a gear wheel and the attachment section coupling 110 is also realized as a gear
wheel, the teeth of the gear wheels meshing with each other in the attached state.
Any other realization of the hand piece power output 311 and the attachment section
coupling 110 known to a skilled person are also possible. In the same manner, the
attachment section power output 111 mates with the head section coupling 210 in the
attached state. In the present example, the hexagon shaft of the attachment section
100 then sits in the respective form-fit hexagon recess provided in the shaft of the
head section coupling 111.
[0019] The hand piece connector structure 320 is arranged to mate with the first attachment
section connector structure 120a in the attached state; in the shown embodiment, the
first attachment section connector structure 120a is realized a undercut structures
that are received by recesses of the hand piece connector structure 320. At least
an element of the hand piece connector structure 320 is movably arranged. In the shown
embodiment, the undercut structures snap-fit onto movably mounted hooks and can be
released from the snapped state by a push button realized on the back of the hand
piece section 300 that moves the hooks against a spring bias. The attachment section
100 and the hand piece section 300 can be detached while the push button is depressed.
Similarly, the head section 200 comprises a head section connector structure 220 and
the attachment section 100 comprises a second attachment section connector structure
120b. The second attachment section connector structure 120b is realized essentially
identical to the hand piece section connector structure 320 and the head section connector
structure 220 is realized essentially identical to the first attachment section connector
structure 120a. As further, the attachment section coupling 110 is designed essentially
identical to the head section coupling 110 the head section coupling 210 and the head
section connector structure 220 can also mate with the hand piece section power output
311 and the hand piece section connector structure 320. A two-part body grooming device
could thus be formed without the attachment section 100, which renders the proposed
body grooming device 1 as specifically versatile.
[0020] Fig. 3 is a perspective view onto an exemplary embodiment of an attachment section
100 in accordance with a body grooming device as proposed. As described with reference
to Fig. 2, the attachment section 100 comprises first and second attachment section
connector structures 120a and 120b, a attachment section coupling 110, and an attachment
section power output 111. The attachment section 100 further comprises an atomizer
unit 170 of which a rotatably mounted brush-like element 171 is visible, which brush-like
element 171 sits within a housing outlet 140. Liquid can be supplied via a liquid
supply outlet 153 during operation of the device and the rotating brush-like element
171 atomizes the liquid into fine droplets that are catapulted out of the housing
outlet 140 by centrifugal forces. Hence, the attachment section 100 as shown adds
a function to the body grooming device, namely provision of atomized liquid. The attachment
section 100 may comprise a liquid supply 150 that comprises a container 151 for storing
a liquid. In another embodiment, the attachment section provides a different functionality,
e.g. it provides a heated vapor to soften skin and hairs or any other functionality.
[0021] Fig. 4 is a schematic depiction of an exemplary embodiment of a body grooming device
1 as proposed. The body grooming device 1 is shown in a detached state for clarification
reasons. The body grooming device 1 comprises a head section 200, an attachment section
100, and a hand piece section 300. The head section 200 comprises a drivable body
grooming unit 230 that is coupled to the head section coupling 210 via a drive shaft
212. The drivable body grooming unit 230 may comprise a gear arrangement or an excenter
extending into an elongated hole to convert the vertical rotational movement that
in the shown embodiment is provided by the drive shaft 212 into a horizontal rotational
movement or into a linear oscillatory movement, respectively. The head section 200
further comprises a head section connector structure 220. The head section connector
structure 220 comprises several undercut elements that are intended to snap-fit into
respective recesses that are part of the second attachment connector structure 120b
when being attached. The hand piece section 300 comprises a drive 330 that in the
shown embodiment is coupled to a hand piece section power output 311 and a second
hand piece section power output 311a via a coupling structure 312. The coupling structure
312 may comprise shafts, gear wheels, and the like. In certain embodiments, the rotational
speeds provided by the hand piece section power output 311 and the second hand piece
section power output 311a are different due to different gear transmission ratios
realized between the drive 330 and the two power outputs. The hand piece section 300
further comprises a hand piece connector structure 320 that has several recesses (indicated
by dotted lines) for receiving undercut elements of the first attachment section connector
structure 120a when being attached. An energy source 335 is arranged in the hand piece
section 300 and a hand piece section electrical contact structure 336 is provided
that is intended for contacting an attachment section electrical contact structure
136 of the attachment section 100 so that energy can be transferred in the attached
state from the energy source 335 to a first powered unit 170 (which may be an atomizer
unit, e.g. an ultrasonic vaporizer) of the attachment section 100. The attachment
section 100 comprises an attachment section coupling 110 and an attachment section
power output 111 that are connected by a first shaft 112. Attachment section coupling
110, attachment section power output 111, and first shaft 112 form the power transmission
unit 190 of the shown embodiment. The attachment section 100 further comprises a second
attachment section coupling 110a, which is intended to mate with second hand piece
section power output 311 a in the attached state. Attachment section coupling 111a
is coupled to a second powered unit 160, which may be a blower unit. The first powered
unit 170 is connected to an electrical contact structure 136 to receive energy from
the energy source 335 present in the hand piece section 300. Alternatively, the attachment
section 100 may comprise an energy source to provide energy to e.g. the first powered
unit 170 or a drive may be arranged in the attachment section 100 to drive the second
powered unit 160 (which is discussed with reference to Fig. 5). The attachment section
100 comprises a second attachment section connector structure 120b that comprises
recesses (indicated by dotted lines) into which the undercut elements of the head
section connector structure 220 will snap when those two sections are attached. The
undercut elements of the head section connector structure 220 and of the first attachment
section connector structure 120a may be realized as flexible elements, e.g. made from
a natural or synthetic rubber, so that they can be released from the snapped state
by pulling the respective section apart with a certain force so that the elasticity
of the flexible elements leads to deformation and thus to unlocking.
[0022] Fig. 5 is a schematic depiction of another embodiment of a body grooming device as
proposed. Elements identical to elements in Fig. 4 are not explained again and reference
is made to the previous paragraph. The hand piece section 300 of the shown embodiment
does not comprise a second hand piece power output anymore but the drive 330 is connected
via drive shaft 312 to the hand piece section power output 311. Hand piece section
300 may nevertheless comprise an energy source to energize the drive 330 or the hand
piece section 300 may be connectable to mains power via a cord. In contrast to the
previous embodiment, the attachment section 100 comprises a drive 130 and an energy
source 135. The energy source 135 is coupled to a first powered unit 170, which may
be an atomizer unit such as an ultrasonic vaporizer. The attachment 100 may further
comprise a container to store a liquid that is vaporized. The drive 130 that is energized
by the energy source 135 is coupled to a second powered unit 160, which may be a blower
unit, via a drive shaft 112a. It is to be understood that Fig. 5 is just illustrating
the possible elements that can be present in an attachment section 100 of a body grooming
device 1 as proposed. In another embodiment, the attachment section 100 comprises
a drive 330 coupled to a powered unit but it does not comprise an energy source but
receives energy through an attachment section electrical contact structure 136 as
depicted in Fig. 4. In another embodiment, attachment section 100 comprises an energy
source 135 coupled to a powered unit 170 but not a drive.
[0023] Depending on the function provided by the attachment section 100, the skilled person
can combine the various discussed elements as needed.
[0024] Fig. 6 is a schematic depiction of the possible elements present in the attachment
section 100 as shown e.g. in Fig. 3 and additionally the drive 330 and drive shaft
312 that are disposed in the hand piece section 300 are shown. Housing and mounting
structures are neglected in Fig. 6 for sake of simplicity. Fig. 6 shows a power transmission
unit 190 and a power extraction unit 180, and further parts of a first powered unit
170 realized as an atomizer unit and of a second powered unit 160 realized as a blower
unit. Further, a liquid supply 150 is shown. The power transmission unit 190 comprises
the attachment section coupling 110, the attachment section power output 111, a first
shaft 112 extending from the attachment section coupling 110, which first shaft 112
ends in a first gear wheel 114, which first gear wheel 114 meshes with a second gear
wheel 115. The second gear wheel 115 is mounted on a second shaft 113 that is connected
with the attachment section power output 111. The first and second gear wheels 114,
115 form a gear section 191 that is used to provide for an offset between the axis
of the first shaft 112 and the axis of the second shaft 113 (in Fig. 6 this is shown
to be a lateral offset but an angular offset may alternatively or additionally be
realized). Depending on, e.g., the geometry and other requirements of the attachment
section 100, the gear section 191 could be dispensed with. In certain embodiments,
the attachment section coupling 110 and the attachment section power output 111 may
hence be connected by a simple drive shaft (these three elements would then form the
power transmission unit 190). In the present embodiment, the drive 330 that is arranged
in the hand piece section has a drive shaft 312 that ends in the hand piece section
power output 311 (indicated with dotted lines), which in Fig. 6 engages with the attachment
section coupling 110. The power extraction section 180 couples to the first gear wheel
114 of the power transmission unit 190 to extract power from the power transmission
unit 190 to drive a fan 161 of the blower unit 160 and a brush-like element 171 of
the atomizer unit 170. It is to be understood that in an embodiment in which no offset
between a first shaft 112 and a second shaft 113 is required, a single shaft extending
between the attachment section coupling 110 and the attachment section power output
111 may be provided with a fixedly mounted gear wheel to couple with the power extraction
unit 180. In the shown embodiment, a third gear wheel 181 meshes with the first gear
wheel 114. The third gear wheel 181 is mounted on a common axis with a first bevel
gear wheel 182. The first bevel gear wheel 182 meshes with a second bevel gear wheel
183 to tilt the rotation axis by 90 degrees from a rotation around a vertical axis
to a rotation around a horizontal axis. The second bevel gear wheel 183 is mounted
on a common axis with a fourth gear wheel 184. The fourth gear wheel 184 meshes with
a fifth gear wheel 185, which fifth gear wheel 185 drives the fan axis 162 on which
the fan 161 is fixedly mounted. The fifth gear wheel 185 meshes with a sixth gear
wheel 186 which in turn meshes with a seventh gear wheel 187. The seventh gear wheel
187 drives the atomizer axis 173 to which the brush-like element 171 is fixedly mounted.
Sizes of the gear wheels and hence gear transmission ratios are chosen according to
the needs of the power extraction section 180 to drive the fan axis 162 and the atomizer
axis 173 at certain rotational speeds. It is to be understood that the exemplary embodiment
shown in Fig. 6 is not to be interpreted as limiting the present invention. It is
a specific embodiment of the general concept and any gear arrangement that would be
considered by a skilled person should also fall under the subject matter of the present
application.
[0025] Fig. 6 further depicts the liquid supply 150. The liquid supply 150 comprises a container
151 and a capillary force element 152 that extends into the container 151. A liquid
that is stored in the container 151 is drawn to the liquid supply outlet 153 by capillary
forces, which are effectual independent on the orientation of the body grooming device.
The capillary force element 151 may be made from a fibrous or porous material. Container
150 and capillary force element 151 can be realized as a replaceable module so that
certain wear of the material of the capillary force element 151 at the liquid supply
outlet 153 due to the mechanical contact with the rotating bristle-like protrusion
172 of the brush-like element 171 is acceptable.
[0026] Figs. 7A - 7D show side views of four exemplary examples of body grooming devices
1 in which various exemplary embodiments of attachment sections 100a - 100d (in the
following labeled as first to fourth attachment section) are used to modify a geometrical
parameter of the body grooming device 1. The body grooming device 1 may, e.g., be
sold in the configuration as shown in Fig. 7A (or a two-part body grooming device
could be sold as basic device). The configuration of the body grooming device 1 shown
in Fig. 7A is characterized by a length of the body grooming device 1 that is influenced
by the length d1 of the first attachment section 100a and an angle α1 between a centre
axis of the hand piece section 300 and a central axis of the head section 200, which
angle is also influenced by the first attachment section 100a. A second attachment
section 100b as shown in Fig. 7B may be sold together with the body grooming device
1 as shown in Fig. 7A or the second attachment section 100b may be sold separately.
Fig. 7B shows the attached state of the body grooming device 1. The second attachment
section 100b has a length d2 that is essentially identical to the length d1 of the
attachment section 100 shown in Fig. 7A, hence d1 = d2. But the second attachment
section 100b provides for a different angle α2 between the central axis of the hand
piece section 300 and the central axis of the head section 200, which angle is larger
than the angle as indicated in Fig. 7A, hence α2 > α1. In Fig. 7C a third attachment
section 100c is shown that has a length d3 that is larger than the length d1 of the
first attachment section 100a shown in Fig. 7A, hence d3 > d1. The angle between the
central axis of the hand piece section 300 and the central axis of the head section
200 is essentially identical to the angle as indicated in Fig. 7A. Fig. 7D shows an
exemplary body grooming device 1 with a fourth attachment section 100d. The fourth
attachment section 100d is about as long as the third attachment section 100c but
provides for an even larger angle α3 between the centre axis of the hand piece section
300 and the centre axis of the head section, hence α3 > α2. Obviously, the shown embodiments
are just illustrations of the general concept of an attachment section and various
other attachment sections do also fall under the subject matter of the present invention.
[0027] The dimensions and values disclosed herein are not to be understood as being strictly
limited to the exact numerical values recited. Instead, unless otherwise specified,
each such dimension is intended to mean both the recited value and a functionally
equivalent range surrounding that value. For example, a dimension disclosed as "40
mm" is intended to mean "about 40 mm."
