  • Patent number: 5099952
    Abstract: A ladder lateral extension, adapted for use with a conventional ladder, includes a generally channel-shaped member adapted to be placed on the siderail of a ladder, such that the siderail fits within the channel-shaped member. The channel-shaped member has opposite interior and exterior sidewalls and a base. A pair of rung-receiving slots are formed in the exterior sidewall, which slots receive the rungs as the channel-shaped member is placed over the siderail. Extending perpendicularly outwardly from the exterior sidewall is a lateral support member of a length equal to or greater than the distance between the rung-receiving slots, thus providing a safe standing area. Safety for the user of the lateral ladder extension is thus greatly increased, due to the engagement of two rungs of the ladder and the length of the lateral support member, which allows the user to safely stand upon it.

  • Patent number: 5097925
    Abstract: A lightweight, portable, tree-climbing device to provide a stable, elevated, horizontal, platfrom utilizing two separate elements for a hunter or observer. The uppermost element accommodates the user in a sitting position while the lower element accommodates his feet. The user faces the tree during the ascending and descending processes but has the option of facing the tree or leaning his back against the tree during his hunting or observing activity. Each element has tubular supporting members, which, along the the ends of the supporting cables, have predrilled holes, thus allowing for the selective adjustment of each element during initial attachment. The device further provides for selective adjustment of the support cables as the user ascends and descends the tree. The device further allows the user to climb past limbs without first having to cut them from the tree.

  • Patent number: 5096069
    Abstract: A calendar accessory for use with a wall calendar of the type having sheets bound in the middle to form pages is constructed of a linear, vertically extending plastic member wherein the length of the member is substantially greater than its width and the width is substantially greater than its thickness. The member has a centrally located clearance hole extending through the member. The hole is adapted for receiving a nail which partially penetrates a vertical surface or wall. The linear member has a depending tab at either end. The calendar holder is used by placing the central hole over a nail embedded in a wall or other vertical surface, after which the calendar is hung by placing it over the supporting nail. The linear member lies behind and along the horizontal upper edge of the suspended calendar.The tabs depend from the upper edge near the ends of the horizontal member and extend outwardly and downwardly to retain the calendar pages.

  • Patent number: 5096018
    Abstract: A method and apparatus are disclosed for securing a manbasket to the tines of a lifting fork of a forklift. A preferred embodiment comprises a tine clamp mounted to a tine socket on the manbasket. The clamp automatically applies a self-adjusting gripping force to the underside of the tine whenever the fork has elevated the manbasket and automatically releases the tine when the manbasket is resting upright on a reference surface. The tine clamp comprises a lever pivotably mounted at mid-length to the tine socket, at least one gripping cam rotatably mounted to one end of the lever, and a cam release member pivotably mounted to the opposite end of the lever. The lever is biased to keep the gripping edge surface of the cam in contact with the underside of the tine whenever the tine is in the socket and the manbasket is elevated. The cam has an outwardly spiraled profile to enable it to apply a gripping force to the tine that increases as the tine is urged more strongly out of the socket.

  • Patent number: 5092427
    Abstract: A convertible ladder-clamp combination as disclosed which includes first and second sides each having upper and lower end portions and a plurality of rungs therebetween. Each upper end portion carries a clamping member between which an object can be clamped when the lower ends of the sides are moved apart. The sides are preferably selectively adjustably connected to each other at the upper portions to thereby vary the spatial relationship between the clamping members to effect clamping of different size objects. At least one of the clamping members may be mounted in a slidable biased relationship to the other of the clamping members to provide a yielding clamping force to an object clamped therebetween which is particularly advantageous when clamping fragile, brittle or like objects.

  • Patent number: 5092426
    Abstract: First and second elongated members are slidable along each other to form a beam of variable length to span the top surface of a structure on which a worker is positioned. Clamping surfaces extend from the ends of the beam to engage the sides of the structure. A lever pivotally mounted on the first elongated member is connected through a link to the second elongated member to shorten the beam and urge the clamping surfaces against the structure. A worker's safety line may be attached to the device such that the lever is locked relative to the first elongated member to secure the device to the structure whenever the safety line is attached.

  • Patent number: 5086875
    Abstract: A folding scaffold for supporting workers and material including a folding frame and a plurality of supporting planks. The frame includes two ladder frames with rungs, which ladder frames are connected by the support frames which hold the ladder frames a spaced distance apart when the scaffold is fully extended. The support frames are of different size and they are hingedly connected to fit in the same plane when the scaffold is in the folded position. The larger support frame protrudes a spaced distance from the smaller support frame when in the same plane to form a handle for easy transport of the scaffold when folded. When fully extended the end of the larger support frame is equi-distant from the ladder frames. The supporting planks extend between the ladder frame and are notched to receive the rungs of the ladder frame to hold the ladder frames in a parallel relation. A removable snap-on spring clip retains the ladder frames in the folded position for transport or storage.
