Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] The present application claims priority to U.S. Provisional
Application No. 61/622,177, filed Apr. 10, 2012 and titled
"Retractable Makeup Brush."
BACKGROUND OF THE INVENTION
[0002] The present invention is directed generally to a retractable
device and, more particularly, a cosmetic or other tool that is
movable or slidable between a retracted position for storage and an
extended position for use.
[0003] Cosmetic tools, such as hand-held brushes, as well known.
Many conventional cosmetic tools include a cover or lid that must
be removed from a body or housing before use to expose a cosmetic
product. Such covers may be inadvertently misplaced, or may
inadvertently damage the tool when the cover is placed onto the
housing to cover the tool for storage. Other conventional cosmetic
tools employ magnets to retract the tool when not in use. However,
such conventional retractable cosmetic tools can be difficult
and/or expensive to produce or manufacture. In addition, it can be
difficult to easily and inexpensively produce such conventional
retractable cosmetic tools where the tool is of an appreciable
size.
[0004] It has yet to be discovered how to create a retractable
cosmetic tool that is easy and relatively inexpensive to produce.
The device of the present application overcomes and/or eliminates
at least one of the above or other shortcomings of such
conventional products.
BRIEF SUMMARY OF THE INVENTION
[0005] Briefly stated, one aspect of the present invention is
directed to a retractable cosmetic device including an outer shell
defining a cavity and an inner shell defining a cavity. At least a
portion of the inner shell is positioned within the cavity of the
outer shell. The inner shell is slidably attached to the outer
shell. At least one slider is positioned within and slidable with
respect to the inner shell. A tool is fixedly attached to the
slider. The tool is movable between an extended position in which
at least a portion of the tool extends outwardly from the inner
shell and a retracted position in which the tool is positioned
within the inner shell.

DETAILED DESCRIPTION OF THE INVENTION
[0016] Certain terminology is used in the following description for
convenience only and is not limiting. The words "front" and "rear"
designate directions in the drawings to which reference is made.
The words "inwardly" and "outwardly" refer to directions toward and
away from, respectively, the geometric center of the device, and
designated parts thereof, in accordance with the present
disclosure. Unless specifically set forth herein, the terms "a,"
"an" and "the" are not limited to one element, but instead should
be read as meaning "at least one." The terminology includes the
words noted above, derivatives thereof and words of similar
import.
[0017] Referring to the drawings in detail, wherein like numerals
indicate like elements throughout, FIGS. 1-9 illustrate a
retractable device, generally designated 10, in accordance with a
preferred embodiment of the present disclosure. The device 10 is
illustrated as a cosmetic brush with bristles or the like (as
described in detail below), such as for applying blush or another
cosmetic product. However, the present disclosure is not limited to
such a device or functionality. For example, the device 10 may be
any of a variety of articles that would benefit from the compact
and retractable features described herein, such as an eating
utensil (i.e., a spoon or a fork), a toothbrush, a writing utensil
(i.e., a pen or a pencil), a flashlight, a screwdriver or the
like.
[0018] Referring to FIGS. 1-3, 5-7 and 9, the device 10 preferably
includes an outer shell or housing 20 that defines a cavity 20a
(see FIGS. 6 and 7). The outer shell 20 includes an open first or
front end 42, an opposing closed second or rear end 44, and a
sidewall 46 extending therebetween. As shown in FIG. 6, a
longitudinal axis A of the device 10 preferably extends linearly
from the front end 42 to the rear end 44 of the outer shell 20. The
outer shell 20 preferably has a generally square or rectangular
cross-sectional shape or area, such that the sidewall 46 is formed
of four at least generally planar surfaces or faces. However, the
outer shell 20 is not limited to the size, shape and/or
configuration shown and described herein. For example, the outer
shell 20 may have a generally circular or ovular cross-sectional
shape or some other cross-sectional shape, such as pentagonal,
hexagonal or the like.
[0019] As shown in FIGS. 3 and 7, an interior surface of two
opposing faces of the sidewall 46 of the outer shell 20 each
includes an indentation 68, 70. Each indentation 68, 70 preferably
has a generally circular cross-section shape and does not extend
completely through the sidewall 46 of the outer shell 20. Each
indentation 68, 70 is preferably positioned proximate to the front
end 42 of the outer shell 20, such as spaced-apart at least
slightly proximally along the longitudinal axis A from the front
end 42. However, the indentations 68, 70 are not limited to the
size, shape and/or configuration shown and described herein. For
example, each indentation 68, 70 may have a generally square
cross-sectional shape or may extend completely through the sidewall
46 of the outer shell 20.
[0020] Referring to FIGS. 1-7 and 9, the device 10 preferably
includes an inner shell or housing 22 that defines a cavity 22a
(see FIG. 9). The inner shell 22 includes an open first or front
end 48, an opposing open second or rear end 50, and a sidewall 52
extending therebetween. The inner shell 22 preferably has a
generally square or rectangular cross-sectional shape or area (see
FIG. 4), such that the sidewall 52 is formed of four at least
generally planar surfaces. However, the inner shell 22 is not
limited to the size, shape and/or configuration shown and described
herein. For example, the inner shell 22 may have a generally
circular or ovular cross-sectional shape or some other
cross-sectional shape, such as pentagonal, hexagonal or the like.
An outer periphery and/or cross-sectional area of at least a
portion of the inner shell 22, such as the rear end 50 and the
sidewall 52 thereof, is preferably at least slightly smaller than
an inner periphery and/or cross-sectional area of the outer shell
22. Both the outer and inner shells 20, 22 are preferably formed of
a light-weight, high-strength material, such as a polymeric or
metallic material.
[0021] At least a portion of the inner shell 22 is positioned
within the cavity 20a of the outer shell 20. More particularly, at
least the rear end 50 and a portion of the sidewall 52 of the inner
shell 22 are preferably positioned within the cavity 20a of the
outer shell 20. It is preferred that the inner shell 22 is movably
or slidably attached to the outer shell 20 along the longitudinal
axis A. Therefore, it is preferred that the inner shell 22 has
generally, if not exactly, the same cross-sectional shape as the
outer shell 20. More particularly, the inner shell 22 is preferably
manually or selectively slidable along the longitudinal axis A by a
user between a first or extended position (see FIGS. 5-7) and a
second or retracted position (see FIGS. 1-3).
[0022] Referring to FIGS. 1-7 and 9, the inner shell 22 preferably
includes an enlarged portion or head 58 proximate the front end 48
thereof. As shown in FIGS. 5-7 and 9, the head 58 preferably has an
outer periphery that extends radially outwardly beyond the rear end
50 and the sidewall 52 when the inner shell 22 is in both the
extended and retracted positions. More specifically, in the
retracted position (FIGS. 1-3), at least a portion of the inner
shell 22, such as the entire head 58, extends outwardly beyond the
front end 42 of the outer shell 20 along the longitudinal axis.
However, in the retracted position, as least a distal surface of
the head 58 may engage or contact a portion of the front end 42 of
the outer shell 20. As shown in FIGS. 3 and 7, at least a portion
of an interior surface of the head 58 includes an arcuate or
concave portion 60.
[0023] As shown in FIGS. 3, 5, 7 and 9, the inner shell 22
preferably includes at least one and more preferably two
spaced-apart or opposing slots 54, 56 in the sidewall 52 thereof.
More particularly, one face or side of the sidewall 52 of the inner
shell 22 includes a first slot 54 extending completely
therethrough, and an opposing face or side of the sidewall 52 of
the inner shell 22 includes a second slot 56 (see FIG. 3) extending
completely therethrough. Each slot 56 preferably extends at least
generally, if not exactly, parallel to the longitudinal axis A and
has a length (measured parallel to the longitudinal axis A) that is
greater than a width (measured perpendicularly to the longitudinal
axis A). The slots 54, 56 preferably have at least a generally, if
not exactly, identical size, shape and/or configuration.
[0024] As shown in FIGS. 2, 3 and 6-9, the device 10 preferably
includes at least one and preferably two or more sliders 32, 34
within the cavity 22a of the inner shell 22. In one preferred
embodiment, a first slider 32 and a second slider 34 are fixedly
attached to form a single slider assembly within the inner shell 22
that is slidable with respect to the inner shell 22. As shown in
FIG. 3, each of the sliders 32, 34 may include a projection 32a,
34a that is received within a corresponding groove 32b, 34b of the
other slider 32, 34. Alternatively, the slider may be a single,
unitary component defining a passageway therein.
[0025] It is preferred that the slider(s) 32, 34 is/are movably or
slidable with respect to the inner shell 22 and, therefore, the
outer shell 20, along the longitudinal axis A. Therefore, it is
preferred that an outer periphery of the slider(s) 32, 34 is/are at
least slightly smaller than an inner periphery of the inner shell
22. More particularly, the sliders 32, 34 are preferably
simultaneously slidable along the longitudinal axis A by a user
between a first or extended position (see FIGS. 6 and 7) and a
second or retracted position (see FIGS. 2 and 3) with respect to
the inner shell 22. In the extended position, the sliders 32, 34
are preferably positioned proximate the front end 48 of the inner
shell 22 and preferably beyond the front end 42 of the outer shell
20 along the longitudinal axis A. In the retracted position, the
sliders 32, 34 are preferably positioned proximate the rear end 50
of the inner shell 22 and the rear end 44 of the outer shell
20.
[0026] Referring to FIGS. 2, 3 and 5-9, the device 10 includes a
tool 36 preferably fixedly attached to either or both sliders 32,
34. More particularly, the device 10 may include a connector 62
(see FIG. 9) that attaches the tool 36 to the slider(s) 32, 34. The
connector 62 has a first or front end or portion 62a that engages
and/or surrounds at least a proximal end of the tool 36. An
opposing second or rear end or portion 62b of the connector 62 may
engage and/or surround either or both of the sliders 32, 34.
[0027] The tool 36 is movable or slidable with respect to the outer
and inner shells 20, 22 along the longitudinal axis A between a
first or extended position (see FIGS. 5-8) and a second or
retracted position (see FIGS. 2 and 3). In the extended position,
at least a portion of the tool 36, such as a front or distal end
thereof, extends outwardly from the inner shell 22 beyond the front
end 48 thereof. In the retracted position, the tool 36 is
positioned entirely within the cavity 22a of the inner shell 22 and
at least partially within the cavity 20a of the outer shell 20.
More particularly, when the tool 36 is in the retracted position
(FIGS. 2 and 3), at least a portion of the tool 36, such as the
front or distal end thereof, extends at least slightly outwardly
beyond the front end 42 of the outer shell 20 along the
longitudinal axis A but remains within the inner shell 22.
[0028] In one preferred embodiment, the tool 36 is a cosmetic brush
having a plurality of bristles 36a (see FIGS. 2 and 7). The
bristles 36a of the brush 36, particularly at their distal ends,
are preferably radially expandable (see FIGS. 5-9) when the brush
36 is in the extended position and are radially compressible,
particularly at their distal ends, (see FIGS. 2 and 3) when the
brush 36 is in the retracted position. Moving the brush 36 from the
extended position to the retracted position does not damage the
bristles 36a of the brush 36 because at least the distal ends of
the bristles 36a readily and easily radially compress against an
interior portion or surface of the inner shell 22 during such
movement. The bristles 36a may extend generally parallel to the
longitudinal axis A when the brush 36 is in the retracted position,
and at least the distal ends of the bristles 36a may extend at a
slight angle, such as approximately thirty degrees, when the brush
36 is in the extended position. Alternatively, the bristles 36a may
extend generally perpendicularly to the longitudinal axis A when
the brush 36 is in the retracted and extended positions, such as if
the brush 36 is a mascara brush.
[0029] The tool 36 is not limited to being a cosmetic brush or even
a brush with the size, shape and/or configuration shown and
described herein. For example, the tool 36 may be any of a variety
of utensils or applicators in which it would be desirable to
conceal during storage, such as a shaving or trimming razor, a pair
of tweezers or scissors, a nail clipper or filer, a cotton swab,
lip gloss or moisturizer and the like. In addition, the tool 36 may
be in any form that would benefit from the retractable and compact
nature of the device 10 described herein.
[0030] As shown in FIGS. 2, 3 and 6-9, the device 10 includes at
least one and preferably two or more straps 28, 30 positioned
within the cavity 22a of the inner shell 22. The strap(s) 28, 30
is/are designed to facilitate movement of the slider(s) 32, 34 and
the tool 36 within the inner shell 22 when the inner shell 22 is
moved or slid with respect to the outer shell 20 by a user. To
facilitate such movement, each strap 28, 30 preferably engages one
or both of the sliders 32, 34, which are preferably fixedly
attached to the tool 36. More particularly, as shown in FIG. 9,
each strap 28, 30 includes a first opening 28a, 30a, respectively,
that preferably engages and or surrounds the projection 32a, 34a of
one of the sliders 32, 34. In addition, as shown in FIGS. 3 and 7,
it is preferred that the straps 28, 30 extend through and/or are
positioned or sandwiched between the two sliders 32, 34. Thus, each
slider 32, 34 is preferably generally fixedly attached to a portion
of one of the straps 28, 30.
[0031] Each strap 28, 30 is preferably rotatable with respect to
the inner shell 22. It is preferred that each strap 28, 30 rotates
in a different rotational direction when the inner shell 22 is
being moved with respect to the outer shell 20, and/or when the
tool 36 is being moved with respect to the inner shell 22. More
particularly, from the perspective shown in FIG. 7, the first strap
28 is rotated in a first rotational direction (e.g., clockwise)
when the tool 36 is moved from the extended position to the
retracted position. The first strap 28 is rotated in a second
rotational direction (e.g., counterclockwise) when the tool 36 is
moved from the retracted position (see FIG. 3) to the extended
position (see FIG. 7). Conversely, from the perspective shown in
FIG. 7, the second strap 30 is rotated in the second rotational
direction (e.g., counterclockwise) when the tool 36 is moved from
the extended position to the retracted position. The second strap
30 is rotated in the first rotational direction (e.g., clockwise)
when the tool 36 is moved from the retracted position to the
extended position.
[0032] Each strap 28, 30 is preferably at least a generally
flexible band. Each strap 28, 30 preferably has a greater length
(as measured parallel to the longitudinal axis A) than width (as
measured perpendicularly to the longitudinal axis A). The straps
28, 30 may be formed of a polyester material or
Polytetrafluoroethylene or TEFLON, for example. Each strap 28, 30
preferably forms a generally closed loop inside the inner shell 22.
Each strap 28, 30 may have a generally ovular shape (see FIG. 9)
when the tool 36 is in the extended position, and may have a
generally eccentric or convoluted shape when the tool is in the
retracted position (see FIG. 3). The flexibility of each strap 28,
30 allows the straps 28, 30 to conform to the shape of other
components of the device 10 when the device is "closed," without
sacrificing the functionality of the straps 28, 30 as described
herein. However, the straps 28, 30 are not limited to size, shape
and/or configuration shown and described herein. Two straps 28, 30
have been found to be beneficial for moving, extending or
retracting relatively large tools 36. However, for more compact
devices 10 and/or smaller tools 36, only a single strap may be
necessary. In such embodiments, the single strap may be a
monofilament line, a braided wire or other such material, which
reduces the spaced occupied by the strap.
[0033] As shown in FIGS. 2, 3 and 6-9, the device 10 includes at
least one and preferably two or more guides 24, 26. In an
embodiment that employs two guides 24, 26, the guides 24, 26
preferably have a generally identical size, shape and/or
configuration. Each guide 24, 26 is preferably fixedly mounted to
the inner shell 22 within the cavity 22a thereof. As shown in FIG.
9, an inner surface of one or more of the sidewalls 52 of the inner
shell 22 includes a groove 22b that receives at least a portion of
one of the guides 24, 26 therein. Engagement of the grooves(s) 22b
and at least a portion of each guide 24, 26 fixedly mounts the
guides 24, 26 within the inner shell 22. It is preferred that each
strap 28, 30 moves or rotates around at least a portion of one of
the guides 24, 26 when the tool 36 is slid between the extended and
retracted positions. More particularly, each strap 28, 30
preferably moves through an opening or space defined between the
guides 24, 26 when the tool 36 is slid between the extended and
retracted positions.
[0034] Referring to FIGS. 2-4 and 6-9, the device 10 includes at
least one and preferably two or more covers 38, 40. Each cover 38,
40 is preferably formed of a flexible and/or resilient material. At
least a portion of each cover 38, 40, such as a rear or proximal
end thereof, is fixedly attached to a portion of one of the straps
28, 30, such that movement or rotation of the straps 28, 30 moves
the covers 38, 40 with respect to the inner shell 22. The covers
38, 40 preferably combine to enclose the tool 36 within the cavity
22a of the inner shell 22 when the tool 36 is slid to the retracted
position (see FIG. 3). When the tool 36 and the inner shell 22 are
in the extended position, each cover 38, 40 preferably extends in a
single plane (see FIG. 8). However, when the tool 36 and the inner
shell 22 are in the retracted position, each cover 38, 40 is
preferably at least partially curved or arcuate. More specifically,
as the tool 36 and the inner shell 22 move from the extended
position to the retracted position, at least a distal portion of
each cover 38, 40 preferably contacts the arcuate interior 60 of
the head 58 of the inner shell 22. As a result, the arcuate
interior 60 guides or forces at least a portion of each cover 38,
40 to curve radially inwardly to eventually close the open front
end 48 of the inner shell 22 to generally enclose the tool 36
within the cavity 22a of the inner shell 22. More particularly, as
shown in FIG. 3, at least a portion of the interior of the head 58
includes an arcuate track 60a that guides the covers 38, 40.
[0035] As shown in FIG. 9, each cover 38, 40 preferably includes an
opening 38a, 40a, respectively, and each strap 28, 30 includes a
second opening 28b, 30b, respectively, spaced-apart from the first
opening 28a, 28b. At least a portion of a first connecting pin 64
extends through the opening 38a of the first cover 38 and through
the second opening 28b of the first strap 28. Similarly, at least a
portion of a second connecting pin 66 extends through the opening
40a of the second cover 40 and through the second opening 30b of
the second strap 30.
[0036] Referring to FIGS. 3 and 7, a radially outwardly extending
portion of each pin 64, 66 preferably extends through at least a
portion of one of the slots 54, 56, respectively, of the inner
shell 22. In addition, a radially outwardly portion of each pin 64,
66 extends at least partially into the corresponding indentations
68, 70 of the outer shell 20. As a result of the pins 64, 66 being
fixedly attached to a portion of the outer shell 20, the pins 64,
66 transfer the relative motion of the outer shell 20 with respect
to the inner shell 22 to the straps 28, 30, which in turn
effectuates movement of the tool 36 and the covers 38, 40, as
described in detail above. The above-described combination of
components allows the tool 36 to be relatively large and the device
10 to be retractable and relatively compact in a "closed"
configuration.
[0037] In operation, to "open" the device 10 or move the tool 36
from the retracted position to the expanded position, the user
preferably moves the inner shell 22 outwardly or distally with
respect to the outer shell 20 along the longitudinal axis A. One
way to accomplish such movement is to hold the outer shell 20
generally stationary and to grasp and move the head 58 of the inner
shell 22 distally along the longitudinal axis A. During such
movement, at least a portion of each pin 64, 66 remains at least
generally fixed in the respective indentation 68, 70 of the outer
shell 20. Meanwhile, inner shell 22 can move with respect to the
pins 64, 66 and the outer shell 20 as a result of the slots 54, 56
of the inner shell 22 moving over or with respect to the pins 64,
66, respectively. The above movement of the inner shell 22 causes
the straps 28, 30 to rotate, as described in detail above. Rotation
of the straps 28, 30 causes the covers 38, 40 to open and
simultaneously moves or forces the sliders 32, 34 and the tool 36
distally along the longitudinal axis A until the tool 36 extends
outwardly beyond the head 58 and the sliders 32, 34 are positioned
proximate to or within the front end 48 of the inner shell 22. Once
the device 10 is in the "open" configuration, the user or
beautician can grasp the device 10 by the outer shell 20 and/or the
inner shell 22, which function(s) as a handle to control or
manipulate the tool 36. A friction force generated by and/or on the
straps 28, 30 may be sufficient to maintain the device 10 in the
"open" configuration unless and until the user desires to place the
device 10 in the "closed" configuration. Additionally or
alternatively, a detent mechanism (not shown) may be formed on or
more of the outer shell 20, the inner shell 22, the straps 28, 30,
the sliders 32, 34 and the guides 24, 26 to at least help maintain
the device 10 in the "open" and/or "closed" configuration.
[0038] To "close" the device 10 to retract the tool 36 for storage
or transportation purposes, the user preferably moves the inner
shell 22 inwardly or proximally with respect to the outer shell 20
along the longitudinal axis A. During such movement, at least a
portion of each pin 64, 66 remains at least generally fixed in the
respective indentation 68, 70 of the outer shell 20. Meanwhile, the
slots 54, 56 of the inner shell 22 move over or with respect to the
pins 64, 66, respectively. The above movement of the inner shell 22
causes the straps 28, 30 to rotate in the reverse direction from
when the device is being "opened." Such rotation of the straps 28,
30 moves or forces the sliders 32, 34 and the tool 36 proximally
along the longitudinal axis A until the tool 36 is positioned
proximate to or within the front end 48 of the inner shell 22 and
proximate to and at least partially within the front end 42 of the
outer shell 20, as also causes the covers 38, 40 to move back to
the "closed" position.
[0039] It will be appreciated by those skilled in the art that
changes could be made to the embodiments described above without
departing from the broad inventive concept thereof. For example,
the straps 28, 30 and/or other components of the device 10 could be
replaced by another type of movement mechanism, such as a
rack-and-pinion design or another gear mechanism. It is understood,
therefore, that this invention is not limited to the particular
embodiments disclosed, but it is intended to cover modifications
within the spirit and scope of the present invention as defined by
the appended claims.
