V. DETAILED DESCRIPTION

[0028] Referring now to the drawings wherein the showings are for purposes of illustrating embodiments of the invention only and not for purposes of limiting the same, and wherein like reference numerals are understood to refer to like components, FIG. 1 shows a crossbow 100 that may use a combination crossbow stirrup and shooting rest mechanism 130 according to some embodiments of this invention. The crossbow 100 may have a main beam 102 including a stock member 104 and a barrel 106. An optional handgrip 108 may be mounted to the main beam 102 in any conventional manner. A trigger mechanism 110 suitable for shooting an arrow is mounted to the main beam 102 in any suitable manner. It should be noted that the crossbow 100 may comprise any trigger mechanism 110 chosen with sound judgment by a person of ordinary skill in the art. The crossbow 100 also includes a bow assembly 112 adapted to propel an arrow and having a bow 114 and a bowstring 116. The bow 114 includes a pair of bow limbs 118, 118 that receive the bowstring 116 in any conventional manner chosen with the sound judgment of a person of ordinary skill in the art. For the embodiment shown, a pair of cams (which may be also pulleys and/or wheels) 120, 120 mounted to the bow limbs 118, 118 receive the bowstring 116 in a known manner; making the bow a compound bow. While the crossbow shown uses a compound bow, it should be understood that this invention will work well with any type of bow chosen with sound judgment by a person of ordinary skill in the art. One or more strings or cables 122, in addition to the bowstring 116, may be interconnected between the wheels 120 and the crossbow 100 in any manner chosen with the sound judgment of a person of skill in the art. The one or more cables 122 may pass through a barrel slot 124 formed in the barrel 106, as shown.

[0029] With continuing reference to FIG. 1, numerous other crossbow components may be used, or not used, with a crossbow using a combination crossbow stirrup and shooting rest mechanism 130 according to some embodiments of this invention. The crossbow 100 may include, for example, a riser or block 126 that is supported to the main beam 102 and that has a pair of limb pockets 128, 128 that support the bow limbs 118, 118, as shown. The combination crossbow stirrup and shooting rest mechanism 130 of this invention may be attached to the riser 126 and may be used as will be discussed below. In alternate embodiments, the combination crossbow stirrup and shooting rest mechanism 130 may be attached directly to the main beam 102 without the use of a riser. In still other embodiments, a riser may work with a bracket as will be discussed below. An optional cocking unit 132 may be provided for use in cocking the crossbow 100 when the stirrup is not used. Still other optional components may include a scope 50 attached to a scope mount 52 that is supported to the main beam 102. Another optional component shown is an arrow retention spring 138. As the operation of these components is well known to those of skill in the art, no further details will be provided.

[0030] FIGS. 2-4 show a combination crossbow stirrup and shooting rest mechanism 200 according to some embodiments of this invention. The combination crossbow stirrup and shooting rest mechanism 200 may include a bracket 202 and a bracket engagement device 208. The bracket 202 may be rotatable with respect to the bracket engagement device 208 and may have a connection surface 224 and a pair of distinct contact surfaces 226, 228 that will be discussed further below. The bracket 202 may have any shape and size chosen with the sound judgment of a person of skill in the art. The bracket shown in FIGS. 2-3 has a contact member 238 with the contact surfaces 226, 228 on opposite sides thereof, an axle or pin 204, and a leg 230 that interconnects the axle 204 to the contact member 238 and thus to contact surface 228. In an alternate embodiment, not shown, the axle or pin 204 may be part of the bracket engagement device 208 instead of part of the bracket 202. The axle 204 may define an axis of rotation 232 about which the bracket 202 is rotatable with respect to the bracket engagement device 208. The contact surface 228 may extend generally parallel to the axis of rotation 232, as shown. The leg 230 may have any shape chosen with the sound judgment of a person of skill in the art. For the embodiment shown, the leg extends generally perpendicular to the axis of rotation 232 but has an outwardly extending portion 234 that increases the areas of the contact surfaces 226, 228. Contact surface 226 may be used to receive the foot of a user when the bracket 202 is used as a stirrup while contact surface 228 may be used to contact a ground or other cocking support surface to cock the bow assembly. A guide lip 236 may be provided to guide the user's foot onto the contact surface 226 when the bracket 202 is used as a stirrup. Contact surface 228 may be used to contact a ground or other shooting support surface when the bracket 202 is used as a shooting rest. The contact surface 228 may be spaced from the axis of rotation 232 a distance 240. Distance 240 can be any distance sufficient to permit the bracket 202 to serve as a stirrup and a shooting rest. In one embodiment, distance 240 is at least 4 inches. In another embodiment, distance 240 is at most 12 inches. In yet another embodiment, distance 240 is between 4 inches and 12 inches, inclusive. In still another embodiment, distance 240 is between 5 inches and 8 inches, inclusive. The connection surface 224 may have a centerline spaced from the axis of rotation 232 a distance 242 that may be in the range of 0.5 inches to 4 inches, inclusive. In another embodiment, distance 242 may be in the range of 1 inch to 2 inches, inclusive.

[0031] With reference now to FIGS. 1-2 and 4, the bracket engagement device 208 may be supportable to the crossbow main beam. In one embodiment, the bracket engagement device 208 is directly supported to the main beam. In another embodiment, the bracket engagement device 208 is supported to the main beam via a riser. In yet another embodiment, the riser serves as the bracket engagement device 208. In this case, reference 208 represents a crossbow riser. For embodiments where axle 204 is part of the bracket 202, the bracket engagement device 208 may have an opening 206 that rotatably receives the axle 204. In one embodiment, the opening 206 is parallel to the flight rail plane of the crossbow. The axle 204 may have a threaded end 214 that receives a washer 216 and a nut 212 or other securing device to mount the axle, and in some embodiments the bracket 202 also, to the bracket engagement device 208. The bracket engagement device 208 may have a counter bore 210 for purposes to be explained below.

[0032] With reference now to FIGS. 2 and 4, the bracket engagement device 208 may have at least two distinct connection surfaces 222 that selectively interconnect with the connection surface 224 of the bracket 202. When bracket connection surface 224 is interconnected to any of the bracket engagement device connection surfaces 222, the bracket 202 is held in position relative to the bracket engagement device 208 as long as the interconnection is maintained. Thus, each connection surface 222 defines a predetermined relative position between the bracket 202 and the bracket engagement device 208. The connection surfaces 222, 224 may be of any type and size chosen with the sound judgment of a person of skill in the art. In one embodiment, the connection surfaces 222 are convex in shape and the connection surface 224 is concave in shape and receives any one of the convex connection surfaces 222. In another embodiment, shown, the connection surfaces 222 are concave in shape and the connection surface 224 is convex in shape. In this case, the convex connection surface 224 is received in any of the concave connection surfaces 222. The specific number and arrangement of connection surfaces 222 can be any chosen with the sound judgment of a person of skill in the art. The connection surfaces 222 may, for the embodiment shown, be arranged on a side surface 220 of the bracket engagement device 208. For the embodiments shown, nine connection surfaces 222 are provided in an evenly divided radial pattern providing a total range of motion of 180 degrees from position A-A to position B-B, as shown in FIG. 4. This provides a range of motion of 22.5 degrees between neighboring connection surfaces, 45 degrees between two connection surfaces having just one connection surface between them (such as 222A and 222E shown in FIG. 4), 90 degrees between position A-A and C-C, 90 degrees between position B-B and C-C, and other ranges of motion as readily understood by a person of skill in the art.

[0033] With reference now to FIGS. 2-4, the combination crossbow stirrup and shooting rest mechanism 200 may include one or more biasing force generators 212 that exert a biasing force to bias the bracket 202 into the position defined by one or more of the bracket engagement device connection surfaces 222. The biasing force generator(s) 212 may therefore provide a positive lock for specific relative bracket/bracket engagement device positions. The biasing force generator(s) used can be of any type and size chosen with the sound judgement of a person of skill in the art. In one embodiment, the biasing force generator 212 is a spring, as shown in FIGS. 2 and 3. The spring 212 may be positioned within the counter bore 210 and around the axle 204, as shown. In another embodiment, discussed further below, the one or more biasing force generators 212 may comprise a spring force inherent to the bracket. The one or more biasing force generators 212 may apply a biasing force automatically. By automatically it is meant that the biasing force is applied naturally as a characteristic of the biasing force generator without human or other intervention. Spring 212, for example, may be a compression spring that, as is well known to those of skill in the art, automatically applies a force resisting compression of the spring. As a result, the spring 212 placed within the counter bore 210 and beside washer 216 will provide a biasing force that biases the bracket connection surface 224 (and thus the bracket 202) into relative position with respect to a bracket engagement device connection surface 222 (and thus with respect to the bracket engagement device 208).

[0034] With reference now to FIGS. 1-4, in operation the user can manually position the bracket 202 into any one of the predetermined positions relative to the bracket engagement device 208 by first pulling the bracket 202 away from the bracket engagement device 208 in direction X-X, shown in FIG. 2. This motion will compress the spring 212, overcoming the spring's biasing force that biases the bracket into the initial relative position, allowing the bracket connection surface 224 to be moved away from (and thus out of interconnection with) the initial engagement device connection surface 222. The bracket 202 can then be manually rotated about the axis of rotation 232 to the desired relative position. Finally, by then manually releasing the bracket 202, the spring biasing force will automatically draw the bracket 202 toward the bracket engagement device 208 and interconnect the bracket connection surface 224 to the juxtaposed engagement device connection surface 222. This biasing force positively locks the bracket 202 in position with respect to the bracket engagement device 208. This process can be repeated as often as desired and the bracket 202 can be positioned relative to the bracket engagement device 208 into any of the positions provided by the engagement device connection surfaces 222.

[0035] Still referring to FIGS. 1-4, assuming, for example, that the orientation shown in FIG. 4 is the same as that shown in FIG. 1 (that is, the front and back directions are the same), to adjust the bracket 202 into a suitable position for use as a stirrup, the user may rotate the bracket 202 into relative position B-B shown in FIG. 4. In this cocking position, bracket connection surface 224 interconnects with engagement device connection surface 222A enabling the user to use the bracket 202 as a stirrup to cock the crossbow bow assembly with contact surface 226 receiving the user's foot and contact surface 228 contacting a ground or other cocking support surface. To adjust the bracket 202 into a suitable position for use as a shooting rest, the user may rotate the bracket 202 into relative position C-C shown in FIG. 4. In this shooting rest position, bracket connection surface 224 interconnects with engagement device connection surface 222B enabling the user to use the bracket 202 as a shooting rest with contact surface 228 contacting a ground or other shooting support surface while the user carefully aims and fires the crossbow. To make the crossbow easier to carry, reducing bracket interference with obstacles, the user may adjust the bracket 202 into a suitable position for carrying the crossbow such as by rotating the bracket 202 into relative position A-A shown in FIG. 4. In this carry position, bracket connection surface 224 interconnects with engagement device connection surface 222C and the bracket 202 is out of the way of interference as it does not extend significantly frontward or downward.

[0036] With continuing reference to FIGS. 1-4, it should be understood that the specific cocking, shooting rest and carry positions just described are exemplary only. In other embodiments, bracket connection surface 224 may interconnect with engagement device connection surface 222D to enable the user to use the bracket 202 as a stirrup. In other embodiments, bracket connection surface 224 may interconnect with engagement device connection surface 222E, 222F, 222G and/or 222H to enable the user to use the bracket 202 as a shooting rest. In still other embodiments, bracket connection surface 224 may interconnect with engagement device connection surface 2221 to enable the user to position the bracket 202 for carrying the crossbow. In some embodiments, the bracket 202 rotates at least 70 degrees with respect to the bracket engagement device 208 about the axis of rotation 232 between the cocking position and the shooting rest position. In other embodiments, the bracket 202 rotates at least 70 degrees with respect to the bracket engagement device 208 about the axis of rotation 232 between the shooting rest position and the carry position. In yet other embodiments, the bracket 202 rotates at least 140 degrees with respect to the bracket engagement device 208 about the axis of rotation 232 between the cocking position and the carry position.

[0037] FIGS. 5-6 show a combination crossbow stirrup and shooting rest mechanism 500 incorporating many of the same embodiments disclosed above but also incorporating alternate embodiments from those disclosed above. The alternate embodiments will be especially noted. The combination crossbow stirrup and shooting rest mechanism 500 may include a bracket 502 that may be rotatable with respect to a bracket engagement device 600. The bracket 502 may have a pair of distinct contact surfaces 508, 510 that are positioned on opposite sides of a contact member 512 and used in the same way as previously described contact surfaces 226 and 228. In some embodiments, the bracket 502 has a single connection surface 506 to selectively interconnect with at least two distinct connections surfaces 602 on the bracket engagement device 600. In another embodiment, shown, the bracket 502 has a pair of connection surfaces 506, 514 on opposite legs 516, 518 that selectively interconnect with at least two distinct connections surfaces 602, 604 on each of the opposite sides 606, 608 of the bracket engagement device 600. The bracket 502 may have any shape and size chosen with the sound judgment of a person of skill in the art and may include one or more (two shown) outwardly extending portions 520 that provide the advantages described above regarding outwardly extending portion 234. Previously described bracket 202 can be thought of as an open design because there is an open space between the bracket and the axle as indicated with brace Z-Z in FIG. 2. Bracket 502, however, has no such open space and thus can be thought of as a closed design.

[0038] With continuing reference to FIGS. 5-6, the bracket 502 may have a pair of axles or pins 504, 504 rotatably received in openings 610, 610 formed on the opposite sides 606, 608 of the bracket engagement device 600. In another embodiment, not shown, the axles 504, 504 may be part of the bracket engagement device 600 instead of the bracket 502. The axles 504, 504 may each define an axis of rotation 522, 524 about which the bracket 502 is rotatable with respect to the bracket engagement device 600. For the embodiment shown, the axes of rotation are collinear. The connection surfaces 602, 604 may be arranged as the connection surfaces 222 described above and shown in FIG. 4. The connection surfaces 506, 514, 602, 604 may be convex and concave in alternative embodiments as with the connection surfaces 222, 224 described above. The contact surface 510 may be spaced from the axes of rotation 522 and/or 524 a distance 526. Distance 526 can be any distance sufficient to permit the bracket 502 to serve as a stirrup and a shooting rest and may have the same range as previously described distance 240. The connection surfaces 506, 514 may, have centerlines that are collinear in some embodiments and non-collinear in other embodiments. These centerlines may be spaced from the axes of rotation 522 and/or 524 a distance 528 that may have the same range as previously described distance 224. If the bracket 502 is made of an appropriate material, such as metal, it will have an inherent spring force. This inherent spring force will maintain the axles 504, 504 within the openings 610, 610. To overcome this spring force to adjust the bracket 502 into a different relative position with respect to the bracket engagement device 600, such as by relative rotation, the user can apply a manual force on both sides as indicated with the arrows 530 in FIG. 5. Once the desired relative position has been achieved, the user may simply release the bracket 502 and the inherent spring force will interconnect the connection surfaces 506, 514 to the desired corresponding connection surfaces 602, 604. As a result, the bracket 502 does not require one or more separate springs as described with other embodiments above. Use and adjustment of the bracket 502 may be similar to bracket 202 described above except for the inherent spring force instead of a separate spring.

[0039] Numerous embodiments have been described herein. It will be apparent to those skilled in the art that the above methods and apparatuses may incorporate changes and modifications without departing from the general scope of this invention. It is intended to include all such modifications and alterations in so far as they come within the scope of the appended claims or the equivalents thereof. Further, the invention as that term is used in this document is what is claimed in the claims of this document. The right to claim elements and/or sub-combinations that are disclosed herein as other inventions in other patent documents is hereby unconditionally reserved.

[0040] In the patent claims that follow, it should be understood that any component referred to as being associated is not being claimed positively but rather indicates the environment in which the claimed invention is used. Thus, for a non-limiting example, if a patent claim includes a combination crossbow stirrup and shooting rest mechanism for use with an associated crossbow then Applicant's intent is that infringement does not require a crossbow. Rather, infringement only requires a combination crossbow stirrup and shooting rest mechanism that is capable of being used with a crossbow.

[0041] Having thus described the invention, it is now claimed:
