  • Patent number: 10017990
    Abstract: A ladder safety device is usable for holding and stabilizing a ladder in a safe and stable manner while being used, by way of securing a ladder relative to continuous horizontal guttering at the edge of a building. The device locks to the gutter by way of locking jaws and is secured to the side rail of a ladder by way of an adjustable locking bar—said locking bar being adjustable in lateral and normal directions. The jaws interact by an over-center relationship with each other. In an alternate embodiment, a trigger and locking mechanism secures the jaws in a closed position while in use.

  • Patent number: 9551183
    Abstract: A house clamp assembly having a fixed jaw and a slide bar mounted movable jaw, the fixed jaw opposing the movable jaw. A one-way drive means, by operation of a trigger handle grip, releasably engages the slide bar and advances the movable jaw towards the fixed jaw. The one-way drive means is incapable of moving the slide bar and movable jaw away from the fixed jaw. A return motion of the movable jaw (separating) is accomplished manually when the one-way drive means is disengaged. A braking lever, which is biased to bind the slide bar, prevents reverse motion of the slideable jaw away from the fixed jaw, except when the first lever is disengaged from the slide bar.

  • Patent number: 9326500
    Abstract: A platform is provided with a ladder to allow the user to easily ascend to the platform. A pair of stabilizing arms and jaws provides lateral stability to the ladder. A climbing stick has a pair of vertical posts attached between the front and rear walls of steps to provide a secure connection. The upper and lower ends extend inwardly and away from each other to provide a gripping surface. A tree stand has a male adapter with a bracket for securing a strap. The strap is used to secure the male adapter in place. Once secured to the tree, the platform area can be attached to the male adapter using a female adapter. The ability to first secure the smaller, lighter bracket and male adapter to a tree before attaching the platform using a female adapter increases the ease in securing the tree stand to a tree.

  • Patent number: 9091120
    Abstract: A platform in combination with ladder-like rails combine to form an add-on device that is connected to a rung near the top of an extension ladder so that the platform is rotatably connected to the extension ladder and the ladder-like rails. In a storage or retracted position, the add-on device is generally co-planar with the extension ladder; and in a use position, the platform can be extended from the extension ladder and directly supported by a roof. The platform acts as a rigid support for the top of the ladder and does not deflect under load. The ladder-like rails act as “grab rails” so that a user can “grab” or hold on to them while walking through the top of the extension ladder. Also, one or more retractable hand rails provide added safety when the user moves onto the platform.

  • Patent number: 6907957
    Abstract: A trench shield ladder that hangs on the wall of the trench shield to provide workmen safe access to a trench. The ladder is provided with a top platform and hand rails that extend over the platform. The ladder can be adjusted in length by employing an extension portion with hooks that hang the extension on the main rungs of the main ladder. The extension portion is not as wide as the main portion of the ladder so that the legs of the extension rest between the legs of the main portion of the ladder. The ladder and extension are provided with stand off arms that hold the main and extension rungs of the ladder away from the wall of the trench shield. The present invention is designed to fit on trench shields of varying thicknesses.

  • Patent number: 6883464
    Abstract: A bird cage ladder equipped with a locking connection mechanism that is biased toward a closed position and is easy to install and remove from a bird cage is disclosed herein. Particular embodiments of the present invention have the flexibility to connect with various shaped bird cages. Other embodiments provide additional ladder stability by limiting the range of movement of the ladder from side-to-side. Utilization of a locking connection mechanism as disclosed makes it very difficult for the ladder to disengage from the bird cage due to rocking caused by a bird. The locking connection mechanisms are releasably connected to the bird cage and bird cage ladder, allowing the bird cage ladder to be easily installed and removed from the bird cage.

  • Patent number: 6820722
    Abstract: A device for erecting roof comprises a portable platform of a size and weight easily lifted and manipulated by a single worker. The platform is configured to fit over the upper ends of the chords of a truss that has already been secured in place so that it can support a worker. By using a pair of the devices, the worker can move from truss to truss, from one end of the roof to the other. The worker moves the device that is not currently in use from one truss to the truss that he has just finished securing in place, and then steps from the device currently in use onto the other device so that the worker is supported on the newly secured truss, in position to guide a new truss into position so that it can be secured. This process is repeated until all trusses have been secured.

  • Patent number: 6729441
    Abstract: The present invention 10 discloses an extension ladder safety adapter that is fabricated from a single elongated strap 22 made of a sturdy, malleable material, preferably metal, wherein each distal end of the strap 22 forms a substantially rectangular side rail retention bracket 18 of a size and shape adequate to accommodate the insertion of an industry standard extension ladder side rail 12 therethrough. Separation of the side walls of the retention bracket 18 is prohibited by a fastening element 20 such as a pop rivet that fastens the foot 30 of each bracket 18 to the bearing strap 22. The retention brackets 18 are secured to the side rails 12 either by sheet metal screws that screw directly into the ladder side rails or by other appropriate non-penetrative pressure-securing means that may reduce damage perpetrated upon the ladder.
