International Classification:

F41B 5/10

US Classification:

124 256

Abstract:

A compound archery bow having a riser and first and second limbs secured to and extending from opposite ends of the riser, each limb having an axle to support a wheel or cam; the limbs have a limb tip angle measured from an unstrung or unflexed limb position to a flexed position at brace height of at least 65 and preferably 75 or more. The bow has an axle-to-axle distance percentage change from an unstrung or unflexed condition to a brace condition of at least 20%. The limbs exhibit a limb tip angle percentage change from brace height to full draw condition of 25% or less of the total limb tip change from unflexed to full draw while the limb tip measured from an unstrung condition to a flexed condition at full draw is at least 80 and preferably 100 or more.

International Classification:

F41B 5/12

US Classification:

124 25

Abstract:

A crossbow accessory for coupling to a modular lower receiver of a rifle includes an elongated frame coupled to a riser at a first end, and coupled above the lower receiver at its second end. An upper housing secured to the second end of the frame includes a rope spool and winding gears for retracting the bowstring toward a drawn position. A rope extends from the rope spool to a bowstring release for retracting the bowstring. The bowstring release is retracted into the upper housing proximate the modular lower receiver for selectively releasing the bowstring when a user pulls the trigger of the lower receiver. A method for creating a crossbow using the modular lower receiver is also disclosed.

Appl. No.:

12/117222

Inventors:

David H. Kronengold - Tucson AZ, US
Scott F. Coffinger - Oro Valley AZ, US
Kevin Hansen - Tucson AZ, US

Assignee:

Precision Shooting Equipment, Inc. - Tucson AZ

International Classification:

F41B 5/14

US Classification:

124 1, 124 86

Abstract:

A portable bow press made of three distinct and separable parts. The first two parts contain loop assemblies made of steel wire formed into a U-shaped loop with the two ends connected via a bolt. The third part is a connection cable with S-hooks on either end that hook into the loop elements. The bolts in the loop assemblies are applied through tooling holes in pulleys on the limbs of a compound archery bow. The bow press is applied once the loop assemblies are in place. The limbs can be forced inward by drawing the bowstring creating enough slack for the connection cable to be hooked on either end to the loops. When the bowstring is released, the limbs are held by tension in the cable and loops to a point where they are closer than at brace height. When the bow press is applied, the bowstring is loose and maintenance can be applied to the bow, before disengaging the bow press.

International Classification:

F41B 5/12

US Classification:

124 25

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.

Abstract:

A crossbow includes an elongated frame coupled to a riser at a first end thereof. The riser supports a pair of flexible limbs, and a bowstring extends between such limbs. A movable bowstring release is used both to retract the bowstring into a drawn position, and to release the bowstring under the operation of a trigger assembly. The bowstring release is initially positioned near the bowstring at rest, and a bowstring hook is engaged therewith. A bowstring retractor includes a retractor rope secured to the bowstring release for retracting the bowstring. An upper housing is secured to the second end of the elongated frame, and supports a rope spool used to wind the retractor rope. The bowstring release is retracted into the upper housing proximate a trigger assembly for selectively releasing the bowstring when a user pulls a trigger.
