  • Patent number: 11643297
    Abstract: A reel take-up apparatus includes a frame, a drive mechanism, a pair of support rollers, and a pair of positioning actuators. The frame may be configured to receive a reel from one end. The drive mechanism is generally slidably mounted to the frame and configured to rotate the reel. The pair of support rollers generally extend from the frame and may be configured to provide support to the reel while allowing the reel to rotate. The pair of positioning actuators may be configured to move the pair of support rollers toward and away from each other so as to (i) lift the reel from a support surface, (ii) support the reel during rotation by the drive mechanism, and (iii) lower the reel to the support surface for removal from the frame.

  • Patent number: 6698549
    Abstract: A tree stand includes a standing section with attachment members, a releasable standing section lashing member attachable to the standing section attachment members, a seating section including seating section attachment members having upper and lower surfaces, and a plurality of spaced holes extending between the upper and lower surfaces, and a seating section lashing member having first and second ends with handles positionable on the upper surfaces of the seating section attachment members, the handles including projections releasibly attachable in selected holes in the seating section attachment members. The tree stand may also include at least one adjustable tie-down strap attachable between the standing section outer end and the standing section inner end, and tree grippers with spaced, parallel trunk-contacting blades attached to the inner ends of the standing and seating sections.

  • Patent number: 6668976
    Abstract: A tree stand that includes a seating section and a standing section, each including inclined attachment bars adjacent the section sides, and seating and standing section cables, each having first and second ends with handles at each of the ends. Each attachment bar has outer and inner faces with a plurality of spaced, aligned attachment holes extending between the faces, and a plurality of spaced, aligned latch holes alternating with the attachment holes. Each of the handles including a pair of flanged projections insertable into adjacent attachment holes in an attachment bar, and a latch pin insertable into a latch hole between the adjacent holes. Each projection is moveable from an insertion position to a locked position within a hole when the cable is tensioned, and is prevented by the latch pin from moving back to the insertion position when the cable is relaxed.
