Publication number: 20230168062Abstract: A crossbow including a riser, a limb coupled to the riser, and a cam assembly rotatably coupled to the limb about an axis of rotation. The cam assembly including a string guide defining a plane of rotation of the cam assembly about the axis of rotation and structured to support a drawstring, a drawstring attachment point structured to engage the drawstring, a power cable journal extending away from the plane of rotation along the axis of rotation and structured to support a power cable, and a power cable attachment point structured to engage the power cable. The power cable journal is shaped to displace the power cable away from the plane of rotation as the crossbow is drawn from a released configuration to a drawn configuration to provide a gap sized to permit the drawstring attachment point and the power cable attachment point to pass between the power cable and the plane of rotation.Type: ApplicationFiled: October 24, 2022Publication date: June 1, 2023Applicant: Ravin Crossbows, LLCInventor: Craig Yehle

Patent number: 11555676Abstract: A high impact strength lighted nock assembly for an arrow that is activated when the arrow is fired with a bowstring. The lighted nock assembly includes a nock molded from a high impact strength, transparent polymeric material containing at least 10% by weight reinforcing fibers. The nock includes a head configured to engage with the bowstring and a shank configured to couple with a rear end of the arrow. The shank includes a recess extending in a distal end of the shank toward the head. A light assembly including a light emitting device is located in the recess in the shank that is electrically coupled to a battery. A switch is electrically coupled to the light emitting device and the battery that is triggered when the arrow is tired to activate the light emitting device.Type: GrantFiled: July 2, 2021Date of Patent: January 17, 2023Assignee: Ravin Crossbows, LLCInventors: Craig Yehle, Fred H. Hunt, Larry Pulkrabek

Patent number: 11408705Abstract: A reduced length crossbow with a trigger located near a midpoint of the crossbow and a small included angle of the draw string when in the drawing configuration that creates a space between the draw string and the user's face. The included angle of the draw string when in the drawing configuration may be less than about 25 degrees. The trigger is typically located proximate the midpoint within about 10% of the overall length of the crossbow.Type: GrantFiled: February 21, 2019Date of Patent: August 9, 2022Assignee: Ravin Crossbows, LLCInventor: Craig Yehle

Patent number: 10139205Abstract: A high impact strength nock assembly that couples with, and decouples from, a bushing mounted in an arrow. The forces applied to the nock during launch are translated to the arrow through the bushing, greatly extending arrow life. For lighted nock applications, the nock translates within the bushing during launch to activate the light. A battery stop is coupled to the battery and releasably coupled within the center opening of the bushing that resists longitudinal translation of the battery relative to the bushing. Consequently, the light can be deactivated without removing the lighted nock assembly from the bushing. The entire lighted nock assembly is removable from the bushing for maintenance and replacement.Type: GrantFiled: June 23, 2017Date of Patent: November 27, 2018Assignee: Ravin Crossbows, LLCInventors: Craig Yehle, Fred Hunt, Larry Pulkrabek
