1. A crossbow assembly, comprising:
- a rail and stock assembly defining a forward and a rearward direction, said rail and stock assembly containing a trigger and a latch mechanism and defining a bolt guide extending from the latch mechanism in the forward direction;
a triangular riser assembly, said triangular riser assembly having;
a crosspiece with a center portion mounted perpendicular to said rail and stock assembly, said crosspiece having a pair of lateral wings, anda pair of bracing struts extending rearward from said lateral wings to an apex;
wherein said wings are non-linear, having a swept-V profile from a top perspective while rising from said center portion to limb mounting portions at a higher height from a horizontal perspective, so that said limb mounting portions are arranged parallel to, yet offset in height from said center portion;
wherein said bracing struts are non-linear both vertically and horizontally, each strut curving laterally outward and upward from the rear to the front; and
,wherein rearward ends of each of said bracing struts are anchored to said rail and stock assembly to form said apex;
a pair of flexible limbs extending horizontally forward from said limb mounting portions in the direction of shooting to limb tips;
a pair of rotatable elements mounted to said limb tips; and
,a bowstring mounted directly between said rotatable elements.

Abstract
A crossbow system is illustrated with a rail, a stock and a riser assembly. In certain embodiments, flexible limbs extend forward from riser assembly, in the direction of shooting, and include cams at the limb tips for the power cable arrangement at their ends. In certain embodiments, the riser assembly is made in a triangular arrangement with a crosspiece and a pair of struts extending rearward and are braced at an apex. Optionally, the crosspiece and struts can be formed separately and connected during assembly, facilitating manufacture and ease of assembly of the crossbow and allowing greater flexibility in the choice of manufacturing methods, materials and mounting arrangements.
