DETAILED DESCRIPTION
[0031] One or more non-limiting exemplary embodiments are disclosed
herein with reference to the accompanying drawings, wherein like
numerals indicate like, but not necessarily identical, elements. It
should be clearly understood that the embodiments described with
reference to the drawings are merely exemplary in that any one or
more of them may be implemented in alternative manner as may become
apparent to a person of ordinary skills. The figures are not
necessarily to scale. Specific structural and/or functional
features and details disclosed herein are not to be construed as
limiting but should rather be treated as a basis for teaching one
of ordinary skills. There is no intent, implied or otherwise, to
limit the disclosure in any way, shape or form to the embodiments
illustrated and described herein. Accordingly, all variants for
providing structures and/or functionalities similar to those
described herein for the exemplary embodiments are considered as
being within the metes and bounds of the instant disclosure.
[0032] FIG. 1 is a side view of a non-limiting exemplary embodiment
of a firing system 10 of the instant disclosure. In some
embodiments, the firing system 10 includes a bowstring carrier 12
and a trigger assembly 14.
[0033] FIGS. 2A and 2B, respectively, are perspective views of a
non-limiting exemplary embodiment of the bowstring carrier 12.
FIGS. 3A-3E are various cross-sectional views of the bowstring
carrier 12.
[0034] In a non-limiting exemplary embodiment, the bowstring
carrier 12 includes a sear 16 and a catch 18. In some embodiments,
the sear 16 is operable between a cocked position 20 illustrated in
FIGS. 3C and 3E and an un-cocked position 22 illustrated in FIGS.
3A and 3B. In certain embodiments, the catch 18 is operable between
a locked position 24 illustrated in FIGS. 3C and 3E and an
un-locked position 26 illustrated in FIGS. 3A, 3B and 3D. As
illustrated in FIG. 3A, in some embodiments, the sear 16 is biased
towards the un-cocked position 22, and the catch 18 is biased
towards the un-locked position 26. In certain embodiments, the
catch 18 is configured for receiving a bowstring (not shown) in the
direction 28.
[0035] In a non-limiting exemplary embodiment, the sear 16 and the
catch 18 are operatively coupled for receiving, retaining, and
releasing the bowstring. As illustrated in FIG. 3B, as the
bowstring is displaced in the direction 28 against the surface 30
of the catch 18, the catch 18 rotates in the direction 32 about the
pivot 34. The end 36 of the catch 18 is displaced in the direction
38 around the bowstring, and the end 40 of the catch 18 is
displaced in the direction 42 along a surface 44 of the sear 16. As
the end 40 of the catch 18 displaces in the direction 42, the sear
16 rotates in the direction 46 about the pivot 48 whereby the tip
50 of the sear 16 is displaced in the direction opposite the
direction 42. The end 40 of the catch 18 and the tip 50 of the sear
16 displace in opposite directions until the end 40 of the catch 18
reaches the peak of the tip 50 of the sear 16. Thereafter, the end
40 of the catch 18 "trips" or "falls" over the peak of the tip 50
of the sear 16 whereby the sear 16 rotates in the direction
opposite the direction 46 and the catch 18 rotates in the direction
opposite the direction 32 until the sear 16 and the catch 18 latch
as illustrated in FIGS. 3C and 3E. As shown, the sear 16 is in the
cocked position 20 and the catch 18 is in the locked position 24
around the bowstring.
[0036] In a non-limiting exemplary embodiment, the bowstring
carrier 12 includes a biasing element 52 interacting with the sear
16, and a biasing element 54 interacting with the catch 18. In some
embodiments, such as illustrated in FIG. 3A, the biasing element 52
biases the sear 16 towards the un-cocked position 22, and the
biasing element 54 biases the catch 18 towards the un-locked
position 26. In certain embodiments, the biasing elements 52 and
54, respectively, are configured or balanced for retaining the sear
16 cocked and catch 18 locked around the bowstring, as illustrated
in FIG. 3C, until an external force 56 applied proximate an end 58
of the sear 16 un-cocks the sear 16 and/or un-locks the catch 18.
In some embodiments, the sear 16 and the catch 18 have
complementary geometries cooperating with the biasing elements 52
and 56 for ensuring the sear 16 remains cocked and the catch 18
remains locked until the external force 56 is applied.
[0037] In a non-limiting exemplary embodiment, the external force
56 applied proximate the end 58 of the cocked sear 16 rotates the
sear 16 in the direction 46 about the pivot 48 whereby the tip 50
of the sear 16 is displaced in the direction opposite the direction
42. The end 40 of the catch 18 is displaced over the tip 50 of the
sear 16 un-locking the catch 18 whereby the end 36 of the catch 18
is displaced opposite the direction 38 exposing the bowstring.
[0038] In some embodiments, the biasing element 54 urges or rotates
the locked catch 18 about the pivot 34 in the direction opposite
the direction 32. In certain embodiments, the un-locking of the
catch 18 is aided by at least some force exerted proximate the end
36 by a drawn bowstring held by the locked catch 18.
[0039] In a non-limiting exemplary embodiment, the trigger assembly
14 is configured for exerting the force 56 for un-cocking the sear
16, un-locking the catch 18, and firing the bowstring held by the
locked catch 18. FIGS. 4A and 4B are perspective views of an
exemplary trigger assembly 14, and FIGS. 4C and 4D are side views
thereof. In some embodiments, the trigger assembly 14 includes a
trigger 60, a trigger roller 62, and a link member 66 operatively
coupling the trigger 60 and the trigger roller 62. In some
embodiments, the trigger 60 is operable between a cocked position
68 shown in FIG. 4C and an un-cocked position 70 shown in FIG. 4D.
In certain embodiments, the trigger assembly 14 includes a biasing
element 72 which biases the trigger 60 in the cocked position 68
shown in FIG. 4C.
[0040] When the cocked trigger 60 is pulled, for example in the
direction 74, the trigger 60 rotates about the pivot 76 causing the
link member 66 to displace in the direction opposite the direction
74 whereby the roller arm 78 and the trigger roller 62 rotate in
the direction 80 about the pivot 82, and the trigger 60 is
un-cocked as shown in FIG. 4D. Then, when the un-cocked trigger 60
is released, the biasing element 72 causes the trigger 60, the link
member 66, the roller arm 78, and the trigger roller 62 to move or
displace in the direction opposite the direction each component
moved when the trigger 60 was pulled, and the trigger 60 returns to
the cocked position 68 shown in FIG. 4C.
[0041] FIG. 5 illustrates a non-limiting exemplary embodiment
wherein the bowstring carrier 12 and the trigger assembly 14 are
operatively coupled with the sear 16 and the trigger 60 in their
respective cocked positions 20 and 68, and the catch 18 in the
locked position 24 around a drawn bowstring (not shown). It will be
apparent to one skilled in the art that FIG. 5 represents an
embodiment described in further detail below wherein the bowstring
carrier 12 with the catch 18 locked around the bowstring has been
fully retracted in the proximal direction towards the user, and the
bowstring carrier 12 and the trigger assembly 14 are held abutting
each other, as shown, with the bowstring fully drawn. The sear 16
in the cocked position 20 and the trigger roller 62 with the
trigger 62 cocked 68 abut, and are operatively coupled, along a
surface 64 of the sear 16.
[0042] As described in the foregoing with reference to FIGS. 4C and
4D, when the trigger 60 is pulled, the trigger roller 62 rotates in
the direction 80 along the surface 64 of the sear 16 and applies
the force 56 to the sear 16 in the cocked position 20. The force
56, as described in the foregoing, causes the sear 16 to rotate to
the un-cocked position 22 whereby the catch 18 rotates to the
un-locked position 26 releasing the bowstring.
[0043] From the foregoing, it should be readily apparent to one
skilled in the art, that the sear 16 must be in the cocked position
20 in order for the catch 18 to un-lock to release the bowstring.
It will also be readily apparent to one skilled in the art that if
the sear 16 is not cocked when the bowstring carrier 12 is
retracted in the proximal direction towards the user, and end 58 of
the sear 16 will abut the trigger roller 62 and stop the movement
of the bowstring carrier 12 in the proximal direction towards the
user inhibiting the sear 16 and the trigger roller 62 from being
operatively coupled.
[0044] In a non-limiting exemplary embodiment, the firing system 10
includes a safety 84 operable between a de-activated position 86
illustrated in FIGS. 3A-3C and an activated position 88 illustrated
in FIGS. 3D and 3E. In some embodiments, the safety 84 includes a
ledge or a shoulder 90 on the safety lever 92.
[0045] In a non-limiting exemplary embodiment, the safety 84 when
in the de-activated position 86 such as that illustrated in FIGS.
3A and 3B permits un-hindered rotation of the sear 16 in the
direction 46 around the pivot 48 enabling the catch 18 to rotate in
the direction 32 around the pivot 34 until the catch 18 locks
around the bowstring and the sear 18 cocks as shown in FIG. 3C. In
a non-limiting exemplary embodiment, when the safety 84 is in the
activated position 88, a ledge or shoulder 90 on the safety lever
92 of the safety 84 and a plateau 94 on the sear 16 abut, as shown
in FIG. 3D, to prevent the sear 16 from being cocked by impeding
the sear 16 from continuing its rotation in the direction 46 around
the pivot 48 whereby the catch 18 is hindered from completing its
rotation in the direction 32 around the pivot 34 and the catch 18
is inhibited from locking around the bowstring. Accordingly, as
will be apparent to one skilled in the art, the safety 84 must
always be in the de-activated position 86 for the catch 18 to lock
around the bowstring and for the sear 16 to cock.
[0046] In a non-limiting exemplary embodiment, the safety 84 when
in the de-activated position 86 such as illustrated in FIGS. 3C and
5 permits the sear 16 to un-cock and the catch 18 to un-lock when
the trigger 60 is pulled and the force 56, as described in the
foregoing with reference to FIGS. 4C and 4D, is applied proximate
the end 58 of the cocked sear 16. In a non-limiting exemplary
embodiment, when the safety 84 is in the activated position 88, the
ledge or shoulder 90 on the safety lever 92 of the safety 84 and
the plateau 94 on the cocked sear 16 abut, as shown in FIG. 3E, to
prevent the sear 16 from un-cocked and the catch 18 from un-locking
when the trigger 60 is pulled and the force 56, as described in the
foregoing with reference to FIGS. 4C and 4D, is applied proximate
the end 58 of the cocked sear 16. Accordingly, as will be apparent
to one skilled in the art, the safety 84 must always be in the
activated position 88 for the sear 16 to un-cock and the catch 18
to unlock. To that end, the safety 84 is configured for being
activated and de-activated manually by the user.
[0047] As described in the foregoing, the safety 84 must be
de-activated for the catch 18 to lock around the bowstring in order
to draw the bowstring, and the sear 16 must be cocked and the
safety 84 must be de-activate in order to pull the trigger 60 and
release the drawn bowstring. Generally, the bowstring, after being
released from the catch 18, will be at a location distal or
downrange from the user, and the bowstring carrier 12 must be moved
to the bowstring with the safety 84 de-activated for the catch 18
to lock around the bowstring. Then, as the "captured" bowstring is
drawn by retracting the bowstring carrier 12 in the proximal
direction towards the user, it would be advantageous to activate
the safety 84 to inhibit the trigger 60 from being pulled, for
example, accidently.
[0048] In a non-limiting exemplary embodiment, the firing system 10
includes a safety reset 96 for respectively activating and
de-activating the safety 84 when the bowstring carrier 12 is
retracted to draw the bowstring and when the bowstring carrier 12
is moved or displaced in the distal direction to "capture" the
bowstring in the catch 18. FIGS. 6A and 6B are perspective views
and FIG. 6C is a side view of a non-limiting exemplary embodiment
of the safety reset 96. In some embodiments, the safety reset 96 is
configured for activating and de-activating the safety 84 as the
bowstring carrier 12 is displaced across the safety reset 96. To
that end, in certain embodiments, the safety reset 96 includes a
reset lever 98 configured for interacting with the safety lever 92
as the bowstring carrier 12 is displaced across the safety reset
96.
[0049] In some embodiments, as the bowstring carrier 12 is moved
from a proximal side to a distal side of the safety reset 96, the
reset lever 98 sufficiently obstructs the movement of the safety
lever 92 across the safety reset 96 so that the safety 84 is
de-activated whereby the catch 18 is enabled to "capture" the
bowstring on the distal side of the safety reset 96.
[0050] In certain embodiments, as the bowstring carrier 12 is
retracted in the proximal direction to draw the bowstring captured
in the catch 18, the bowstring carrier 12 moves from the distal
side to the proximal side of the safety reset 96 and the reset
lever 98 sufficiently obstructs the movement of the safety lever 92
across the safety reset 96 so that the safety 84 is activated
whereby the trigger 60 is inhibited from being pulled accidently
until the safety 84 is de-activated.
[0051] In a non-limiting exemplary embodiment, the reset lever 98
is configured as a biasing element to "give" or deflect and yet
exert sufficient force on the safety lever 92 to activate or
de-activate the safety 84 as the bowstring carrier 12 moves across
the safety reset 96.
[0052] In another non-limiting exemplary embodiment, the safety
reset 96 includes a biasing element 100 configured for interacting
with the reset lever 98. In some embodiments, the biasing element
100 is configured to permit the reset lever 98 to "give" or deflect
and yet allow the reset lever 98 to exert sufficient force on the
safety lever 92 to activate or de-activate the safety 84 as the
bowstring carrier 12 moves across the safety reset 96.
[0053] In a non-limiting exemplary embodiment, the firing system 10
does not have the safety reset 96. In some exemplary embodiments,
the user activates and de-activates the safety 84. In a
non-limiting exemplary embodiment, the safety reset 96 is
configured as an "obstruction element" with or without biasing
properties such as, for example, a protrusion or a bar (e.g.,
dowel) extending across the width of the center rail 122 or a bulge
or the head of a bolt, etc.
[0054] In a non-limiting exemplary embodiment, the catch 18
activates and de-activates the safety. In some exemplary
embodiments, the catch 18 and the safety 84 are operatively
coupled. In certain exemplary embodiments, if the safety 84 is in
the activated position 88, the un-locked catch 18 first
de-activates the safety 84 before locking around the bowstring. Of
course, if the safety 84 is already de-activated, then the catch 18
does not need to de-activate the safety 84 before locking around
the bowstring.
[0055] In a non-limiting exemplary embodiment, the safety 84 does
not include the safety lever 92. In some exemplary embodiments, the
safety 84 and the safety reset 96 interact or operate cooperatively
to activate and de-activate the safety 84 as the bowstring carrier
12 moves across or over the safety reset 96.
[0056] Because, as described in the foregoing, the safety 84 must
be de-activated before the trigger 60 can to pulled to release the
drawn bowstring held by the catch 18, it will be readily apparent
to those skilled in the art that the safety 84, most likely, will
be in the de-activated position 86 as it traverses or is moved or
displaced from the proximal side to the distal side of the safety
reset 96. Therefore, in some exemplary embodiments, the safety
reset 96 ensures or makes certain that the safety 84 is in fact
de-activated just in case it was activated deliberately by the user
and/or accidently got activated.
[0057] As is well known in the art, dry-firing a bow, i.e.,
releasing a drawn bowstring without a nocked arrow or bolt to
absorb the released energy, can be dangerous to the user and/or
damage the equipment. In a non-limiting exemplary embodiment, the
firing system 10 includes a dry-fire inhibitor 102 configured to
"capture" or "arrest" a drawn bowstring released without a nocked
bolt or arrow. In some embodiments, the dry-fire inhibitor 102
includes a biasing element 104 configured to bias the dry-fire
inhibitor 102 "upright" or in an activated position 106 to capture
the drawn bowstring if released without a nocked bolt or arrow.
FIG. 3C illustrates one such exemplary embodiment wherein the sear
16 is cocked, the catch 18 is locked about a drawn bowstring (not
shown), the safety 84 is de-activated, and the dry-fire inhibitor
102 is activated since an arrow or bolt has not been nocked onto
the drawn bowstring. As will be readily apparent to one skilled in
the art, and as described in the foregoing, the drawn bowstring,
without the nocked bolt or arrow, will be released if the trigger
60 is accidently or deliberately pulled. As will also be apparent
to one skilled in the art, the released bowstring will be
immediately "arrested" or "captured" or "stopped" at the surface
108 of the upright or activated dry-fire inhibitor 102. With the
safety 84 in the de-activated position 86, the user may then
advance or move the bowstring carrier 12 towards the dry-fire
inhibitor 102 to "grab" the bowstring and lock the catch 18 around
the bowstring. The bowstring carrier 12 can then be retracted in
the proximal direction to again fully draw the bowstring.
[0058] In a non-limiting exemplary embodiment, the dry-fire
inhibitor 102 is configured to rotate or bias out of the path of
the drawn bowstring when an arrow or bolt is nocked. FIG. 7
illustrates one such exemplary embodiment, albeit without a nocked
arrow or bolt, wherein the sear 16 is cocked, the catch 18 is
locked about a drawn bowstring (not shown), the safety 84 is
de-activated, and the dry-fire inhibitor 102 is in a de-activated
position 110. As will be apparent to one skilled in the art, the
dry-fire inhibitor 102 will be de-activated by the shaft (not
shown) of the nocked arrow or bolt (not shown) in the groove 112 of
the bowstring carrier 12. Then, when the trigger 60 is accidently
or deliberately pulled, the bowstring will be released from the
catch 18, and the nocked arrow or bolt will be propelled downrange.
Of course, the biasing element 104 is configured to ensure that the
dry-fire inhibitor 102 remains de-activated for a sufficient amount
of time to inhibit the bowstring from being prematurely captured or
arrested by the dry-fire inhibitor 102.
[0059] In a non-limiting exemplary embodiment, the biasing element
104 is a torsion spring. In some embodiments, the biasing element
104 is not a spring. In a non-limiting exemplary embodiment, the
dry-fire inhibitor 102 does not include the biasing element 104. In
some embodiments, the dry-fire inhibitor 102 itself is a biasing
element configured for being in the activated position 106 in the
absence of a nocked arrow or bolts, and in the de-activated
position 110 in the presence of a nocked arrow or bolt. Any and all
other alternatives providing the required functionality are
considered as being within the metes and bounds of this
disclosure.
[0060] In a non-limiting exemplary embodiment, the end 40 of the
catch 18 includes a roller configured for rotating as the end 40 is
displaced along the surface 44 of the sear 16. In some embodiments,
the end 44 of the catch 18 is rounded or curved. In certain
embodiments, the surface 44 of the sear 16 includes a groove or a
channel configured as a guide or track along which the end 40
moves. In some embodiments, the end 40 of the sear 16 and the
surface 44 of the sear 16 are substantially smooth or slippery to
permit their un-hindered movement against each other. In certain
embodiments, the end 40 of the sear and the surface 44 of the sear
16 are configured to minimize or eliminate friction therebetween as
they move or slide against each other.
[0061] In a non-limiting exemplary embodiment, the trigger roller
62 is configured for rotating along the surface 64 of the sear 16.
In some embodiments, the trigger assembly 14 includes a rounded or
curved end or surface instead of the trigger roller 62. In certain
embodiments, the surface 64 of the sear 16 includes a groove or a
channel configured as a guide or track along which the trigger
roller 62 rotates or alternatively along which the rounded or
curved end or surface of the trigger assembly 14 moves. In some
embodiments, the rounded or curved end of the trigger assembly 14
and the surface 64 of the sear 16 are substantially smooth or
slippery to permit their un-hindered movement against each other.
In certain embodiments, the rounded or curved end of the trigger
assembly 14 and the surface 64 of the sear 16 are configured to
minimize or eliminate friction therebetween as they move or slide
against each other.
[0062] In a non-limiting exemplary embodiment, the bowstring
carrier 12 includes a housing 114. In some embodiments, the sear 16
and the catch 18 are disposed or housed within the housing 114. In
a non-limiting exemplary embodiment, the safety 84 is disposed or
housed within the housing 114. In a non-limiting exemplary
embodiment, the dry-fire inhibitor 102 is disposed or housed within
the housing 114. In a non-limiting exemplary embodiment, the sear
16, the catch 18, the safety 84, and the dry-fire inhibitor 102 are
disposed or housed within the housing 114. In some embodiments, the
safety 84 is external of the housing 114. In certain embodiments,
the dry-fire inhibitor 102 is external of the housing 114. In some
embodiments, the safety 84 and the dry-fire inhibitor 102 are
external of the housing 114.
[0063] FIGS. 8A and 8B, respectively, are perspective and side
views of a non-limiting exemplary embodiment of a crossbow 116
equipped with an exemplary embodiment of the firing system 10 of
the instant disclosure. FIGS. 9A and 9B are perspective views and
FIG. 9C is a side view of the relevant portions of the crossbow 116
to which the firing system 10 is coupled with or attached to or
installed on.
[0064] In a non-limiting exemplary embodiment, the crossbow 116
includes a pair of substantially parallel rails 118a and 118b
extending between the proximal and distal ends of the crossbow 114.
In some embodiments, the rails 118 are cylindrical shaped, i.e.,
have a circular cross-section. In certain embodiments, the rails
118 have an oval or oblong cross-section. In some embodiments, the
rails 118 have a triangular cross-section. In some embodiments, the
rails 118 have a polygon shaped cross-section. Any and all other
geometries for the rails 118 that are or may become apparent to a
person of ordinary skill are considered as within the metes and
bounds of the instant disclosure.
[0065] In a non-limiting exemplary embodiment, the bowstring
carrier 12 is slidably coupled to the rails 118 and configured for
being displaced along the rails 118 between the proximal and distal
ends of the crossbow 116. In some embodiments, the housing 114 has
an external complementary surface 120a and 120b for slidably
coupling the bowstring carrier 12 between the rails 118. In certain
embodiments (not shown), the rails 118 extend through an interior
of the bowstring carrier 12.
[0066] In some embodiments, the crossbow 116 includes a center rail
122 extending between the proximal and distal ends of the crossbow
116. In a non-limiting exemplary embodiment (not shown), the
bowstring carrier 12 is slidably coupled to the center rail 122 and
configured for being displaced along the center rail 122 between
the proximal and distal ends of the crossbow 116. In a non-limiting
exemplary embodiment, the cross-section of the center rail 122 is
any one of circular, oval, oblong, polygonal, and any and all other
geometries that are or may become apparent to a person of ordinary
skill. In some embodiments, the housing 114 has an external
complementary surface for slidably coupling the bowstring carrier
12 and the center rail 122 to each other. In certain embodiments
(not shown), the center rail 122 extends through an interior of the
bowstring carrier 12.
[0067] In a non-limiting exemplary embodiment, the trigger assembly
14 is fixedly attached to the center rail 122 proximate the
proximal end 124 of the center rail 122. In a non-limiting
exemplary embodiment, the safety reset 96 is fixedly attached to
the center rail 122 in the path of the bowstring carrier 12 as it
moves between the proximal and distal ends of the crossbow 116.
[0068] In a non-limiting exemplary embodiment, the bowstring
carrier 12 and the trigger assembly 14 are discrete components
configured for abutting against each other. In a non-limiting
exemplary embodiment, the bowstring carrier 12 and the trigger
assembly 14 are discrete components configured for being removably
attached to each other. In a non-limiting exemplary embodiment, the
bowstring carrier 12 and the trigger assembly 14 are discrete
components fixedly attached to each other. In a non-limiting
exemplary embodiment, the bowstring carrier 12 and the trigger
assembly 14 are a unitary component.
[0069] In a non-limiting exemplary embodiment, the crossbow 116
includes a retractor 126 configured for drawing the bowstring
locked in the catch 18 by retracting or pulling the bowstring
carrier 12 toward or to the proximal end of the crossbow 116. In a
non-limiting exemplary embodiment, the retractor 126 is a winch
such as the non-limiting exemplary embodiments disclosed in
Applicant's co-pending patent application number PCT/US19/55159
which is herein incorporated by reference in its entirety.
[0070] In a non-limiting exemplary embodiment, the retractor 126
includes one or more straps and/or one or more cables having an end
attached to the bowstring carrier 12. In a non-limiting exemplary
embodiment, rotating a crank or handle 128 of the retractor 126 in
a first direction pulls on the straps and/or the cables to retract
or displace the bowstring carrier 12 towards the proximal end of
the crossbow 116. In certain embodiments, retracting or pulling the
bowstring carrier 12 draws the bowstring locked in the catch 18. In
some embodiments, the retractor 126 pulls on the bowstring carrier
12 until it abuts a housing 130 of the trigger assembly 14. In a
non-limiting exemplary embodiment, the retractor 126 holds or
retains the bowstring carrier 12 with the drawn bowstring abutting
the housing 130 of the trigger assembly 14 proximate the proximal
end of the crossbow 116.
[0071] In a non-limiting exemplary embodiment, rotating the crank
or handle 128 of the retractor 126 in a second direction opposite
the first direction unwinds the straps and/or the cables from the
retractor 126. If the bowstring carrier 12, more specifically the
catch 18, no longer holds the bowstring, i.e., after the bowstring
has been released, unwinding the straps and/or the cables from the
retractor 126 creates a slack in the straps and/or the cables which
then enables the user to manually displace or move the bowstring
carrier 12 towards the bowstring for locking the catch 18 around
the bowstring. If the drawn bowstring is still held or locked in
the catch 18, then unwinding the straps and/or the cables enables
or permits or provides for controlled movement or displacement of
the bowstring carrier 12 towards the distal end of the crossbow 116
under the influence of the energy stored in the limbs of the
crossbow 116 and/or the force of the drawn bowstring.
[0072] In a non-limiting exemplary embodiment, the retractor 126
retracts or pulls the bowstring carrier 12 to the proximal end of
the crossbow 116 for being removably attached to the trigger
assembly 14 at the proximal end of the crossbow 116. In a
non-limiting exemplary embodiment, the retractor 126 retracts or
pulls the bowstring carrier 12 to the proximal end of the crossbow
116 for being fixedly attached to the trigger assembly 14 at the
proximal end of the crossbow 116. In a non-limiting exemplary
embodiment, the retractor 126 retracts or pulls the bowstring
carrier 12 to the proximal end of the crossbow 116 for being
removably attached to the rails 118 at the proximal end of the
crossbow 116. In a non-limiting exemplary embodiment, the retractor
126 retracts or pulls the bowstring carrier 12 to the proximal end
of the crossbow 116 for being fixedly attached to the rails 118 at
the proximal end of the crossbow 116. In a non-limiting exemplary
embodiment, the retractor 126 retracts or pulls the bowstring
carrier 12 to the proximal end of the crossbow 116 for being
removably attached to the center rail 122 at the proximal end of
the crossbow 116. In a non-limiting exemplary embodiment, the
retractor 126 retracts or pulls the bowstring carrier 12 to the
proximal end of the crossbow 116 for being fixedly attached to the
center rail 122 at the proximal end of the crossbow 116. In a
non-limiting exemplary embodiment, the retractor 126 retracts or
pulls the bowstring carrier 12 to the proximal end of the crossbow
116 for being removably and/or fixedly attached to one or more of
the trigger assembly 14, the rails 118 and the center rail 122 at
the proximal end of the crossbow 116.
[0073] In a non-limiting exemplary embodiment, the straps and/or
the cables of the retractor 126 extend through the housing 128 of
the trigger assembly 14.
[0074] In a non-limiting exemplary embodiment, the crossbow 116
includes a retractor (not shown) having one or more straps and/or
one or more cables having ends configured for being removably
attached to the bowstring prior to drawing the bowstring and for
being detached from the bowstring after the bowstring has been
drawn and locked in the catch 18 of the bowstring carrier 12. In a
non-limiting exemplary embodiment, rotating the crank or handle of
the retractor in a first direction pulls on the straps and/or the
cables to retract or displace the bowstring towards the catch 18 of
the bowstring carrier 12. Once the catch 18 is locked around the
bowstring, the straps and/or the cables can be detached from the
bowstring.
[0075] In a non-limiting exemplary embodiment, rotating the crank
or handle of the retractor in a second direction opposite the first
direction unwinds the straps and/or the cables from the retractor.
If the bowstring carrier 12, more specifically the catch 18, no
longer holds the bowstring, i.e., after the bowstring has been
released, unwinding the straps and/or the cables from the retractor
creates a slack which then enables the user to attach the straps
and/or cables to the released bowstring. If the drawn bowstring is
still held or locked in the catch 18, then unwinding the straps or
the cables enables or permits or provides for controlled movement
or displacement of the drawn bowstring towards the distal end of
the crossbow 116 under the influence of the energy stored in the
limbs of the crossbow 116 and/or the force of the drawn
bowstring.
[0076] In a non-limiting exemplary embodiment, one or both biasing
elements 54 and 56 are compression springs. In a non-limiting
exemplary embodiment, one or both biasing elements 54 and 56 are
expansion springs. It will be apparent to one skilled in the art
that the location and/or the configuration of the biasing elements
54 and 56 is not limited to those illustrated.
[0077] In view thereof, modified and/or alternate configurations of
the non-limiting exemplary embodiments illustrated and described
herein may become apparent or obvious to one of ordinary skill. All
such variations are considered as being within the metes and bounds
of the instant disclosure. For instance, while reference may have
been made to particular feature(s) and/or function(s), this
disclosure is considered to also encompass any and all equivalents
providing functionalities similar to those described herein with
reference to the accompanying drawings. Accordingly, the spirit,
scope and intent of the instant disclosure embraces all variations.
Consequently, the metes and bounds of the instant disclosure are
