  • Patent number: 7849964
    Abstract: The present disclosure relates to tree stands which grasp upright columnar members for example, trees, poles, which are arranged to facilitate climbing and adjusting the height of the tree stand to a desired level and angle. When assembled as a cart, the invention consists of an upper climbing member or frame, lower climbing member or frame, a mechanical-interlocking system, an axle, wheels and a wheel attachment device. The two-climbing-member tree stand may be of a manually adjusting type or of a self-adjusting type which permit adjustment of the spacing of the grasping members so as to effect adjustment of the angle of each tree climber relative to the upright columnar member.

  • Patent number: 6948732
    Abstract: The present invention is directed to a convertible cargo rack that can be configured in one of two positions. In the first configuration, the cargo rack is suspended behind a vehicle, and in the second configuration, the cargo rack is pulled behind the vehicle in a trailer-like fashion. In the first configuration, the cargo rack has at least two tubular receivers on its underside that correspond to at least two tubular receivers attached to the rear of the vehicle. Support bars are inserted into the receivers to suspend the cargo rack behind the vehicle. In the second configuration, the cargo rack is rotated 90 degrees and wheels are attached to the sides of the cargo rack. A trailer bar then pivotably attaches the cargo receiver to the vehicle's center tubular receiver so that the cargo rack can be pulled behind the vehicle in a trailer-like fashion. The tubular receivers that are secured to the vehicle are attached using a bracket that can accommodate vehicle support frames of various sizes and shapes.

  • Patent number: 5297656
    Abstract: A fixed position tree stand having extendable vertical members for adjusting the height of the seat and extendable and retractable diagonal support members for adjusting the angle of the footrest.The invention includes an inverted U-shaped tubular frame having two extendable and retractable substantially vertical arms. The U-shaped frame is hung from a T-shaped screw handle attached to a tree. The footrest is pivotally attached at the rear thereof to the extendable and retractable vertical arms. Extendable and retractable support arms are pivotally mounted diagonally between the front of the footrest to the upper end of the extendable and retractable vertical arms. The diagonal extendable and retractable support arms permit the angle or inclination of the footrest to be adjusted. Provision is made to permit incremental automatic retraction or extension of the diagonal members by the combination of a locking pin assembly and a resilient biasing member mounted on each diagonal member.

  • Patent number: 5285868
    Abstract: A tree climber comprising a pair of climbing members, adapted to be affixed to the user's feet by quick release straps. Each climbing member includes a support arm extending forward from a platform portion and terminating at one end of a movable hook shaped clamping portion which engages the back side of the pole. Several embodiments show a clamping portion which is adjustably affixed to the terminus of the support arm with either a slidable collar and tube configuration or a clamped configuration. Another embodiment includes a slidable collar affixed to the platform portion, the support arm extending therethrough to a desired length corresponding to the diameter of the pole. The adjustable clamping portion of any of the embodiments may be used in combination with the extendable support arm to accommodate a wide range of tree trunk or pole diameters and to easily traverse protruding limbs which would otherwise arrest further vertical progress.

  • Patent number: 4669194
    Abstract: The present invention relates to an archery bow sight having a bracket mounted at the mid-section of the box. The bracket has a pair of vertical parallel slots therein, and a plurality of horizontally and vertically adjustable sight pins are mounted within the vertical slots of the bracket. Each sight pin in the first vertical slot is aligned with a sight pin in the second vertical slot so that it can be used to sight a target at a specific distance from the bow, and each pair of sight pins is adjusted for sighting targets at different distances from the bow. When using the sight of the present invention, the archer first estimates the distance between the target and the bow, and then determines which pair of sight pins is best adjusted for a target at that distance. The archer then sights the target using the properly adjusted pair of sight pins.
