DETAILED DESCRIPTION
[0040] Immaterial modifications may be made to the embodiments described here
without
departing from what is covered by the claims. In the claims, the word
"comprising" is used
in its inclusive sense and does not exclude other elements being present. The
indefinite
articles "a" and "an" before a claim feature do not exclude more than one of
the feature
being present. Each one of the individual features described here may be used
in one or more
embodiments and is not, by virtue only of being described here, to be
construed as essential
to all embodiments as defined by the claims.
[0041] Referring to Figs. 1 - 5, there is disclosed an embodiment of a body
forming a razor
handle 12 having a first end 14 and a second end 16. The first end 14 of the
handle 12 is
formed as one part 18A of a quick release connector 18 (see Fig. 8 and 22 for
the entire
quick release connector 18). The part 18A includes a housing 22 that forms a
cylinder
opening outward. As shown in Figs. 3 and 4, the housing 22 has a latching
component 24 for
removably holding a piston in the housing 22. The latching component 24 may
comprise an
interior groove 26 containing a latching element 28. The latching element 28
may for
example be a canted coil spring. The housing 22 may have for example a
generally
cylindrical shape. The latching component 24 may operate using any suitable
releasable
latching mechanism such as snap fit joints. Although the housing 22 is shown
here as being
on the handle 12, the piston part of the quick release connector 18 may
instead be on the
handle 12 in any of the disclosed embodiments.
[0042] The female part 18A of the quick release connector 18 allows the handle
12 to be
connected to a male part 18B (piston) of the quick release connector 18, the
male part 18B
CA 02928818 2016-05-04
being shaped to fit in the housing 22, thus allowing a variety of functional
heads to be
connected to the housing 22.
[0043] Figs. 6¨ 8 disclose a further embodiment of a razor 10 comprising a
handle 12
having a first end 14 and a second end 16 and the handle 12 having one part
18A of
the quick release connector 18 at the first end 14. A safety razor head 30 has
a razor blade 32
and a piston 34 extending from the head 30 away from the razor blade 32. The
piston 34 and
housing 22 together form the quick release connector 18, with the piston 34
inserted in the
housing 22. The embodiment shown of the quick release connector 18 has a
latching
component 24 for removably holding the piston 34 in the housing 22 of the
handle 12. The
latching component 24 may comprise a groove 26 containing a latching element
28. The
latching element 28 may be for example a canted coil spring. The piston 34 may
have angled
outer surfaces or indents 36 corresponding to the latching component 24.
[0044] Referring to Figs. 6¨ 13, an embodiment of a razor 10 may comprise a
handle 12 for
gripping the razor 10, the handle 12 having a first end 14 and a second end
16, the handle 12
having a core 38 and a removable sleeve 40, the sleeve 40 having a hollow
interior shaped to
allow the sleeve 40 to slide onto the core 38, and a razor head 30 attached to
the handle 12 at
the first end 14. The razor head 30 may be a safety razor head or cartridge
razor head. The
sleeve 40 may for example be made from any type of material to create a
variety of
decorative finishes including but not limited to polished, chromed, anodized,
colored,
printed, and including such materials as aluminum, copper, brass, gold,
silver, platinum,
tungsten, stainless steel, titanium, wood, resin, carbon fibre. The sleeve 40
may be decorated
using UV cured inkjet technology, silkscreen technology or application of a
printed plastic
sleeve. Resin may include any type of poured, cast, or machined synthetic or
semi-synthetic
organic polymers of high molecular mass commonly called 'plastic'. The sleeve
40 allows
users of the razor 10 to change the appearance or shape of the exterior of
handle according to
preference. In an alternative embodiment, the sleeve 40 may be permanently
fixed to the
core 38.
[0045] The core 38 may be solid or hollow and may be made of for example metal
or resin
material. The diameter of the core may be sized to fit the inside diameter of
the sleeve 40 to
allow the sleeve 40 to be slid over the core. In an embodiment, the portion of
the core 38
CA 02928818 2016-05-04
closer to the first end 14 of the handle 12 may be larger in diameter than the
diameter
diameter of the sleeve to act as a stop 42 for the sleeve 40. The diameter of
the core 38, and
the corresponding diameter of the sleeve 40, may vary over the length of the
core 38 and
sleeve 40.
[0046] The sleeve 40 may include multiple sleeve sections. The sleeve 40
exterior may form
any desired shape, including for example round, square, triangular, or ribbed.
The sleeve 40
may be secured to the core by for example gluing, friction, fit or
magnetically. The sleeve 40
may also or alternatively be secured in place by a bottom cap 44, attached to
the second end
16 of the handle 12, as shown in Figs. 1 ¨ 3. Several views of the bottom cap
44 are shown
in Figs. 14 - 17. The bottom cap 44 may be removably fixed to the handle 12 in
a variety of
ways, including for example by screwing or a snap fit. Bottom cap 44 may for
example have
an inner groove 46 and a pin element 48. The inner groove 46 may cooperate
with a
corresponding ridge on second end 16 of the handle 12 to form a stop for the
sleeve 40 so
that the sleeve 40 does not slide off of the core 38 in use. The pin element
48 may help the
user align the bottom cap 44 with the handle 12. The sleeve 40 may incorporate
a variety of
materials including stones (precious or non-precious), electronic components
such as LEDs
or electroluminescent wire. The sleeve 40 may have for example an inner radius
of 0.278 ¨
0.288 inches.
[0047] As shown in Figs. 6 ¨ 8, the housing 22 of the quick release connector
18 may be
covered with a top cap 50. Figs. 18 - 21 show several views of the top cap 50.
Top cap 50
may provide protection for the quick release connector 18. Top cap 50 may
slide onto the
quick release connector and abut against the first end 14 of the handle 12.
[0048] Referring to Figs. 22 ¨ 26, an embodiment of a razor 20 comprises a
handle 12
having a first end 14 and a second end 16. At the first end of the handle 12
is a female part
18A of a quick release connector 18 for receiving male part 18B that is
attached to a neck 52
of a cartridge connector 53. The cartridge connector 53 has a body extending
between the
female part 18A of the quick release connector 53 and an adaptor portion 54
for connecting
to a razor cartridge. The adaptor portion 54 has a substantially trapezoidal-
shaped cross-
section, wherein the trapezoid forming the trapezoidal-shape is an acute
trapezoid. The
roughly trapezoidal-shape may have non-linear sides or may have more than four
edges.
CA 02928818 2016-05-04
[0049] The adaptor portion 54 may be used to connect the razor handle 12 to a
variety of
razor cartridges, and for this reason is referred to as a universal adaptor,
although it will be
understood that universal in this context only means that several cartridge
heads may be
connector to the cartridge connector. The adaptor portion may be made of a
flexible, resilient
material to allow different shapes and sizes of razor cartridges to be
inserted into the adaptor
portion 54.
[0050] Referring to Figs. 6 ¨ 8 and 27 - 36, an embodiment of a razor head 30
comprises a
blade 32 mounted to a razor base 58 and a silver coating or strip 60 fixed to
the razor base 58
and adjacent to the blade 32. The silver coating or strip 60 may be for
example a silver strip
running parallel to the razor blade 32 along the razor base 58. The silver
coating or strip 60
may be affixed to discrete sections of the razor base 58 which are adjacent to
the blade 32.
The silver coating or strip 60 may replace a lubrication strip on the razor
base 38. The silver
coating or strip 60 may provide a natural antibacterial protection while
shaving. The razor
head 30 may be any type of razor cartridge with any number of blades. Fig. 27
shows a
cartridge head having a silver strip 60, razor blades 32 and wiper blade 62
[0051] The razor base 58 may be the base of a cartridge razor such as for
example the
cartridge shown in Fig. 27, or a safety razor such as for example a razor base
in Figs. 31- 34.
The razor base may have tapered walls 64 to provide swarf clearance. The razor
base 58 may
be for example 1.015 ¨ 1.025 inches in width, 1.625 ¨ 1.635 inches in length
and 0.200 ¨
0.210 inches in height.
[0052] A safety razor head 30 may include a blade cap 62 as shown in Figs. 28
¨ 30, which
connects to the razor base such as the blade cap shown in Figs. 28 ¨ 30. The
blade cap has a
blade or blades 32. The blade cap 62 may have dimensions of for example 0.76 ¨
0.78 inches
in width, 1.60¨ 1.61 inches in length and 0.572 ¨ 0.582 inches in height. The
blade cap may
include a single blade or multiple blades. The blade cap 62 may have connector
pins or
pistons 66 which may be inserted into the razor base 58. In a typical safety
razor blade cap,
the central pin may be a screw.
