Modular Crossbow
Abstract
A crossbow comprising a tiller, a prod and a trigger mechanism.
The tiller comprises a butt and at least one track, and is
configured to support a bolt. The prod comprises a bow; a bow
string; and a bow base arranged to connect the bow to the track(s).
The trigger mechanism is arranged to hold the bow string in a
cocked state and to allow releasing the bow string and thereby
shooting the bolt. Either the prod; the trigger mechanism; or both,
are movably connected to the track(s) such that cocking the bow
string utilizes the movable connection. The crossbow exhibits a
predefined drawing weight. One crossbow comprises a force enhancing
mechanism arranged to allow cocking the bow string with a cocking
weight substantially smaller than the predefined drawing weight,
utilizing the movable connection of the prod, the trigger
mechanism, or both, to the track(s).

DETAILED DESCRIPTION
[0019] Before explaining at least one embodiment of the invention
in detail, it is to be understood that the invention is not limited
in its application to the details of construction and the
arrangement of the components set forth in the following
description or illustrated in the drawings. The invention is
applicable to other embodiments or of being practiced or carried
out in various ways. Also, it is to be understood that the
phraseology and terminology employed herein is for the purpose of
description and should not be regarded as limiting.
[0020] FIG. 1 is a schematic illustration of a crossbow 100
according to some embodiments of the invention. Crossbow 100
comprises a tiller 125, a prod 140, a trigger mechanism 160, and
may further comprise a basis 131 for supporting a bolt (not shown),
sights (not shown, mountable on sights basis 170), a bolt magazine
(not shown) connected to tiller 125, and so forth. Tiller 125
comprises a butt 110 and at least one track 120. Tiller 125 is
configured to support a bolt (not shown), e.g. upon basis 131
connected to tiller 125. Bolts may be loaded upon tiller 125 from
the bolt magazine. Prod 140 comprises a bow string 150 (shown in
FIG. 1A), a bow 141 and a bow base 142. Bow base 142 is arranged to
connect bow 141 to tracks 120. Trigger mechanism 160 is arranged to
hold bow string 150 in a cocked state and to allow releasing bow
string 150 and thereby shooting the bolt.
[0021] According to some embodiments of the invention, tracks 120
may comprise either one, two, or any number of tracks 120
configured to allowing convenient operation of crossbow 100, and
providing enough strength to tiller 125. For example, tracks 120
may comprise two parallel tracks 120 posited at either sides of the
bolt and below a horizontal plane comprising the bolt.
Alternatively, tracks may be posited above the bolt or at a lateral
configuration. Tracks 120 may comprise a single track, below, above
or lateral to the bolt. For example, the single track may be
posited on a perpendicular plane comprising the bolt.
[0022] According to some embodiments of the invention, crossbow 100
may comprise attachment means 135 for further parts such as a
bipod.
[0023] FIGS. 1A, 1B and 1C are schematic illustrations of a
crossbow exhibiting various drawing possibilities, according to
some embodiments of the invention. In FIG. 1A, trigger mechanism
160 is movable (via movable connection 180) along tracks 120 and
arrange to hold bow string 150 and allow drawing bow string 150
together with trigger mechanism 160 backwards to a shooting
position (e.g., as in FIG. 1).
[0024] Referring to FIG. 1B, prod 140 is movable (via movable
connection 180 of bow base 142) along tracks 120 backwards. Bow
string 150 may be attached, or hooked, onto trigger mechanism 160,
and then prod 140 may be pushed back--in the forward direction in
respect to crossbow 100, and so allowing drawing bow string 150. In
both FIG. 1A and FIG. 1B, trigger mechanism 160 serves as an
anchorage for bow string 150 before the application of the drawing
forces.
[0025] According to some embodiments of the invention, either prod
140, trigger mechanism 160 or both may be movably connected (180)
to tracks 120 such that cocking bow string 150 is carried out
utilizing movable connection 180. Further elements may be movably
connected to tracks 120 such as basis 131 or the bolt magazine, and
these too may be arranged to allow cocking bow string 150. Both
prod 140 and trigger mechanism 160 may be movably connected (180)
to tracks 120, such that their relative motion allow drawing bow
string 150.
[0026] Referring to FIG. 1C, crossbow 100 may further comprise a
drawing element 144 movably connected (via movable connection 180)
to tracks 120 and arranged to entrain and allow cocking bow string
150. Drawing element 144 is arranged to fixate bow string 150, and
allow drawing bow string 150 from its lax position near prod 140 to
a drawn (and cocked) position at trigger mechanism 160. When
drawing element 144 is movably connected to tracks 120, prod 140
and trigger mechanism 160 may be fixated to tracks 120.
[0027] According to some embodiments of the invention, crossbow 100
exhibits a predefined drawing weight. Crossbow 100 may further
comprise a force enhancing mechanism (not shown) arranged to allow
cocking bow string 150 with a cocking weight substantially smaller
than the predefined drawing weight. The force enhancing mechanism
is arranged to utilize movable connection (180) of prod 140,
trigger mechanism 160, drawing element 144, or any of their
combinations to tracks 120. The force enhancing mechanism may
comprise various mechanical appliances for enhancing the cocking
weight.
[0028] FIG. 2 is a high level schematic flowchart illustrating a
method of configuring a crossbow, according to some embodiments of
the invention. The crossbow comprises a tiller, a prod comprising a
bow string, and a trigger mechanism. The method comprises the
stages: connecting at least one track to the tiller (stage 200);
and connecting the prod and the trigger mechanism to the track
(stage 205). The connection is arranged to allow a modular assembly
of the crossbow. The method may comprise connecting one track, two
tracks or more at various configurations to reach an optimal force
application and operation convenience. According to some
embodiments of the invention, connecting the prod and the trigger
mechanism to the tracks (stage 205) comprises movably connecting
either the prod, the trigger mechanism or both to the track (stage
210), such that cocking the bow string is carried out utilizing the
movable connection.
[0029] According to some embodiments of the invention, the crossbow
exhibits a predefined drawing weight, and the method further
comprising the stages: connecting a force enhancing mechanism to
the crossbow (stage 215); and arranging the force enhancing
mechanism to allow cocking the bow string with a cocking weight
substantially smaller than the predefined drawing weight (stage
220). The force enhancing mechanism utilizes the movable connection
of either the prod, the trigger mechanism or both to the track.
[0030] According to some embodiments of the invention, the method
further comprises the stages: movably connecting a drawing element
to the tracks (stage 225); and arranging the drawing element to
allow cocking the bow string (stage 230). According to some
embodiments of the invention, the crossbow exhibits a predefined
drawing weight, and the method further comprising the stages:
connecting a force enhancing mechanism to the crossbow (stage 215);
and arranging the force enhancing mechanism to allow cocking the
bow string with a cocking weight substantially smaller than the
predefined drawing weight (stage 220). The force enhancing
mechanism utilizes the movable connection of the drawing element to
the track.
[0031] According to some embodiments of the invention, the method
further comprises connecting at least one accessory to the tiller
(stage 235). Accessories may comprise a bolt magazine; a basis
configured to support the bolt; sights; and bipod.
