Abstract

A crossbow includes a barrel with a bowstring rail and an arrow support area on the rail. An arrow retention spring is carried by the barrel for releasably holding the arrow on the arrow support area prior to launch. The arrow support area includes a first arrow rest area adjacent to an end of the bowstring rail and a second arrow rest area beneath the arrow retention spring. An arrow on the barrel is out of contact with and spaced from the bowstring rail except in the first and second rest areas. Provision of the spaced rest areas, particularly the second rest area beneath the arrow retention spring, stabilizes an arrow on the barrel prior to launch.

Claims

1. A crossbow that includes:

a barrel with a bowstring rail and an arrow support area along a length of said bowstring rail for positioning an arrow to be shot, and an arrow retention spring carried by said barrel for releasably holding an arrow on said arrow support area,

characterized in that

said arrow support area includes a first arrow rest area adjacent to an end of said bowstring rail, and a second arrow support area beneath said arrow retention spring and being spaced from and not connected to said first arrow rest area, wherein said first and second arrow rest areas are aligned along said bowstring rail,

an arrow on said barrel being spaced and out of contact with said barrel and said bowstring rail except in said first and second arrow rest areas, such that said arrow does not touch said bowstring rail in a clearance area between said first and second arrow rest areas,

wherein said second arrow support area is directly beneath said arrow retention spring in a location where said arrow retention spring contacts said arrow.

2. The crossbow set forth in claim 1 wherein said first and second arrow rest areas together comprise not more than 75% of the total length of said bowstring rail.

3. The crossbow set forth in claim 2 wherein said first and second arrow rest areas together comprise about 20% of the total length of said bowstring rail.

4. The crossbow set forth in claim 1 wherein said first arrow rest area is of less length than said second arrow rest area.

5. The crossbow set forth in claim 4 wherein said first arrow rest area is about one-half the length of said second arrow rest area.

6. A crossbow includes:

a barrel with a bowstring rail and an arrow support area along a length of said bowstring rail for positioning an arrow to be shot,

characterized in that

said arrow support area includes a first arrow rest area adjacent to an end of said bowstring rail, and a second arrow rest area spaced from and not in contact with said first arrow rest area, with an arrow clearance area between the first and second arrow rest areas,

an arrow on said barrel being spaced and out of contact with said barrel and said bowstring rail except in said first arrow rest area and in said second arrow rest area, and

an arrow retention spring carried by said barrel for releasable holding said arrow on said second arrow rest area of said barrel, wherein said second arrow rest area is positioned directly beneath said arrow retention spring in a location where said arrow retention spring contacts said arrow,

wherein said first arrow rest area comprises less than 10% of the total length of said bowstring rail, and has a length in the range of one-quarter inch to three inches.

7. The crossbow set forth in claim 6 wherein the first and second arrow rest areas together comprise not more than 75% of the total length of the bowstring rail.

8. The crossbow set forth in claim 7 wherein the first and second arrow rest areas together comprise about 20% of the total length of the bowstring rail.

9. The crossbow set forth in claim 6 wherein the first arrow rest area is of less length than the second arrow rest area.

10. The crossbow set forth in claim 9 wherein the first arrow rest area is about one-half the length of the second arrow rest area.

11. The crossbow set forth in claim 6 wherein an arrow is supportable on the barrel spaced and out of contact with the barrel and the bowstring rail except in the first and second arrow rest areas.
