Abstract

Provided is a bow assembly comprising a main beam elongated in a first direction to define a distal end, and a proximal end, wherein the distal end has a distal end facing surface from which extend, an upper member, and a lower member having a first set of threads thereon; and a riser having a proximate facing surface, an upper groove dimensioned to engage the upper member, and a lower opening through hole dimensioned to engage the lower member; a threaded fastener adapted to threadedly engaged the first set of threads; and wherein the riser is assembled with the main beam and the threaded fastener such that the upper member is inserted within the upper groove, the lower member is inserted within the lower opening, the distal end facing surface faces the proximate facing surface, and the threaded fastener is threadedly engaged with the first set of threads.

Claims

1. A bow assembly comprising

a main beam elongated in a first direction to define

a distal end, and

a proximal end opposite the distal end,

wherein the distal end has a distal end facing surface from which extend,

an upper member elongated in the first direction, and

a lower member separate from the upper member, the lower member,

being elongated in the first direction, and

having a first set of threads thereon;

and

a riser having

a proximate facing surface,

an upper groove dimensioned to engage the upper member in a close sliding fit, and

a lower opening through hole dimensioned to engage the lower member in a close sliding fit;

a threaded fastener having a second set of threads adapted to threadedly engaged the first set of threads; and

wherein the riser is assembled with the main beam and the threaded fastener such that

the upper member is inserted within the upper groove,

the lower member is inserted within the lower opening,

the distal end facing surface faces the proximate facing surface,

the threaded fastener is threadedly engaged with the first set of threads.

2. The bow assembly of claim 1, wherein the lower member is generally cylindrical.

3. The bow assembly of claim 2, wherein the upper member,

has a generally V-shaped cross-section, and

includes an upper surface with an arrow receiving slot therein.

4. The bow assembly of claim 3, wherein the upper member has

a lower surface,

a first wall of the upper member extending upward and outwardly, and

a second wall of the upper member extending upward and outwardly.

5. The bow assembly of claim 4, wherein the first wall of the upper member has

a lower laterally extending arm,

a mid-portion laterally extending arm, and

an upper laterally extending arm.

6. The bow assembly of claim 5, wherein the second wall of the upper member has

a lower laterally extending arm,

a mid-portion laterally extending arm, and

an upper laterally extending arm.

7. The bow assembly of claim 6, wherein the threaded fastener is a nut.

8. The bow assembly of claim 7, further comprising a first attachment bracket engaged to the riser with a dovetail tongue and groove interconnection.

9. The bow assembly of claim 7 further comprising a power cable pulley inset into riser.

10. The bow assembly of claim 7, further comprising a bowstring dampener attached to the riser.

11. A method of assembling a bow assembly comprising

providing a main beam, the main beam being elongated in a first direction to define

a distal end, and

a proximal end opposite the distal end,

wherein the distal end has a distal end facing surface from which extend,

an upper member elongated in the first direction, and

a lower member separate from the upper member, the lower member,

being elongated in the first direction, and

having a first set of threads thereon;

and

providing a riser, the riser having

a proximate facing surface,

an upper groove dimensioned to engage the upper member in a close sliding fit, and

a lower opening through hole dimensioned to engage the lower member 300 in a close sliding fit;

providing a threaded fastener, the threaded fastener having a second set of threads adapted to threadedly engaged the first set of threads;

inserting the riser onto the main beam such that the

the upper member is inserted within the upper groove,

the lower member is inserted within the lower opening, and

the distal end facing surface faces the proximate facing surface; and

threadedly engaging the threaded fastener with the first set of threads.

12. The method of assembling a bow assembly of claim 11, wherein the lower member is generally cylindrical.

13. The method of assembling a bow assembly of claim 12, wherein the upper member,

has a generally V-shaped cross-section, and

includes an upper surface with an arrow receiving slot therein.

14. The method of assembling a bow assembly of claim 13, wherein the upper member has

a lower surface,

a first wall of the upper member extending upward and outwardly, and

a second wall of the upper member extending upward and outwardly.

15. The method of assembling a bow assembly of claim 14, wherein the first wall of the upper member has

a lower laterally extending arm,

a mid-portion laterally extending arm, and

an upper laterally extending arm.

16. The method of assembling a bow assembly of claim 15, wherein the second wall of the upper member has

a lower laterally extending arm,

a mid-portion laterally extending arm, and

an upper laterally extending arm.

17. The method of assembling a bow assembly of claim 16, wherein the threaded fastener is a nut.

18. The method of assembling a bow assembly of claim 17, further comprising a first attachment bracket engaged to the riser with a dovetail tongue and groove interconnection.

19. The method of assembling a bow assembly of claim 17 further comprising a power cable pulley inset into riser.

20. A crossbow comprising

a main beam elongated in a first direction to define

a distal end, and

a proximal end opposite the distal end,

wherein the distal end has a distal end facing surface from which extend,

an upper member elongated in the first direction,

having a generally V-shaped cross-section, and

including an upper surface with an arrow receiving slot therein, and

a generally cylindrical lower member separate from the upper member, the lower member,

being elongated in the first direction, and

having a first set of threads thereon;

and

a riser having

a proximate facing surface,
