Abstract

A crossbow has a riser, flexible limbs, a bowstring extending between the tips of the limbs for propelling an arrow, and an elongated frame extending from the riser. A bowstring release proximate the rear end of the elongated frame includes a trigger for releasing the bowstring, and firing an arrow. A first grip is disposed proximate to the trigger for being grasped by the user'"'"'s first hand. A “Picatinny” type support rail extends along and below the elongated frame, secured at its rearmost end to the elongated frame, but otherwise spaced therefrom. The support rail can receive fore-grips, a bi-pod, or can be rested against a support surface to help steady the crossbow during firing.

Claims

1. A crossbow comprising in combination:

a. a riser having a central portion and opposing end portions;

b. first and second limbs coupled to the opposing end portions of the riser, the first limb extending from the riser toward a first limb tip, and the second limb extending from the riser toward a second limb tip;

c. a bowstring extending between the first limb tip and the second limb tip for propelling an arrow;

d. an elongated frame member having front and rear opposing ends, the front end being coupled to the riser,

e. a bowstring release coupled to the rear end of the elongated frame member, the bowstring release having a trigger mechanism adapted to be operated by a finger on a user'"'"'s first hand, the bowstring release being responsive to the trigger mechanism for selectively releasing the bowstring when a user operates the trigger mechanism;

f. a first grip disposed proximate to the trigger mechanism and being adapted to be grasped by the user'"'"'s first hand; and

g. a rail having opposing front and rear ends thereof, the rail extending along and below the elongated frame member, the rear end of the rail being secured generally proximate to the rear end of the elongated frame member, the front end of the rail extending forwardly generally toward the front end of the elongated frame member and spaced apart therefrom, the rail avoiding physical coupling with the riser except proximate to the rear end of the rail, the rail being adapted to assist the user in supporting the crossbow during release of the bowstring.

2. The crossbow recited by claim 1 wherein the rail is integral with said elongated frame member.

3. The crossbow recited by claim 1 wherein the rail is adapted to receive a support member.

4. The crossbow recited by claim 3 wherein the support member is a second grip.

5. The crossbow recited by claim 4 wherein the second grip is slidingly received by the rail.

6. The crossbow recited by claim 1 wherein the rail has a generally T-shaped cross-section and includes a series of ridges interspersed with flat spacing slots.

7. A crossbow comprising in combination:

a. a riser having a central portion and opposing end portions;

b. first and second limbs coupled to the opposing end portions of the riser, the first limb extending from the riser toward a first limb tip, and the second limb extending from the riser toward a second limb tip;

c. a bowstring extending between the first limb tip and the second limb tip for propelling an arrow;

d. an elongated frame member having front and rear opposing ends, the front end being coupled to the riser,

e. a bowstring release coupled to the rear end of the elongated frame member, the bowstring release having a trigger mechanism adapted to be operated by a finger on a user'"'"'s first hand, the bowstring release being responsive to the trigger mechanism for selectively releasing the bowstring when a user operates the trigger mechanism;

f. a first grip disposed proximate to the trigger mechanism and being adapted to be grasped by the user'"'"'s first hand; and

g. a rail having opposing front and rear ends thereof, the rail extending along and below the elongated frame member, the rear end of the rail being secured generally proximate to the rear end of the elongated frame member, the front end of the rail extending forwardly generally toward the front end of the elongated frame member and spaced apart therefrom, the rail avoiding physical coupling with the elongated frame member except proximate to the rear end of the rail, the rail being adapted to assist the user in supporting the crossbow during release of the bowstring.

8. The crossbow recited by claim 7 wherein the rail is integral with said elongated frame member.

9. The crossbow recited by claim 7 wherein the rail is adapted to receive a support member.

10. The crossbow recited by claim 9 wherein the support member is a second grip.

11. The crossbow recited by claim 10 wherein the second grip is slidingly received by the rail.

12. The crossbow recited by claim 7 wherein the rail has a generally T-shaped cross-section and includes a series of ridges interspersed with flat spacing slots.

13. A crossbow comprising in combination:

a. a riser having a central portion and opposing end portions;

b. first and second limbs coupled to the opposing end portions of the riser, the first limb extending from the riser toward a first limb tip, and the second limb extending from the riser toward a second limb tip;

c. a bowstring extending between the first limb tip and the second limb tip for propelling an arrow;

d. an elongated frame member having front and rear opposing ends, the front end being coupled to the riser,

e. a bowstring release coupled to the rear end of the elongated frame member, the bowstring release having a trigger mechanism adapted to be operated by a finger on a user'"'"'s first hand, the bowstring release being responsive to the trigger mechanism for selectively releasing the bowstring when a user operates the trigger mechanism;

f. a first grip disposed proximate to the trigger mechanism and being adapted to be grasped by the user'"'"'s first hand; and

g. a rail having opposing front and rear ends thereof, the rail extending along and below the elongated frame member, the rear end of the rail being secured generally proximate to the rear end of the elongated frame member, the front end of the rail extending forwardly generally toward the front end of the elongated frame member and spaced apart therefrom, the front end of the rail terminating before reaching the riser, the rail being adapted to assist the user in supporting the crossbow during release of the bowstring.

14. The crossbow recited by claim 13 wherein the rail is integral with said elongated frame member.

15. The crossbow recited by claim 13 wherein the rail is adapted to receive a support member.

16. The crossbow recited by claim 15 wherein the support member is a second grip.

17. The crossbow recited by claim 16 wherein the second grip is slidingly received by the rail.

18. The crossbow recited by claim 13 wherein the rail has a generally T-shaped cross-section and includes a series of ridges interspersed with flat spacing slots.
