  • Patent number: 8544856
    Abstract: A skid shoe for a snowthrower is provided that includes a selected dual-faced, dual-angled approach surface, and an elongate footprint as compared to prior skid shoe devices. The skid shoe includes a runner element and a mounting flange element, each of which has dimensions and contours configured to maximize utility when mounted to a snowthrower. In particular, the skid shoe provides for smoothened operation of a snowthrower moving across uneven surfaces and/or abrupt transitions.

  • Publication number: 20110085884
    Abstract: A multi-directional scaffold transport device, which may be attached to each base of a scaffold's legs, provides increased mobility in relation to movement atop corrugated floor decking with vertical anchor studs used in conventional steel I-beam superstructures. The device comprises an elongated flat plate with angled extensions. The angled extensions may form a trapezoidal shape, or more preferably a triangular shape, and may be curved or have compound curvature to enable deflection of the device to either side of any anchor stud encountered, rather than jamming thereon. The elongated flat plate may have minimal length sufficient to normally receive support from at least two peaks of the corrugated decking. The device may incorporate threaded studs protruding from the elongated flat plate, which may be received by holes in the base of the scaffold, and be removeably fastened thereto using nuts. The device may also incorporate vertical walls for increased stiffness.

  • Publication number: 20030042727
    Abstract: A furniture moving device including a circular sliding section made of substantially friction-free material with a lip formed at a periphery of the circular sliding section and a support section made of a substantially compressible material fixedly attached at a position substantially centered on the circular sliding section. The support section supports a ground contact of furniture, such as a leg or edge, so that the ground contact does not slide with respect to the support section. When force is applied to the furniture, the ground contact of the furniture remains in contact with the support section and moves along with the circular sliding section as the circular sliding section slides along the surface in the direction in which the force is applied.

  • Patent number: 6464256
    Abstract: A furniture slide for placement between an object to be moved and flooring over which it is to be moved, which includes a sheet of flexible material having top and bottom faces and complex curvature on the bottom face with a concave curvature along the longitudinal axis thereof and a convex curvature along the transverse axis thereof. A compressible material is adhered to the top face for support contact with an object to be moved.

  • Patent number: 6206424
    Abstract: A furniture slide for moving furniture over a floor surface and also serving to provide foam drying blocks under the furniture for placement on wet carpet surfaces. The furniture slide of the present invention includes a sheet of material having a convex bottom base for sliding on a floor surface and further includes compressible material that is adhered to the top face of the sheet for support contact with the furniture to be moved. This compressible material is precut whereby a plug of the compressible material may be readily removed therefrom to provide a cavity in the compressible material. Then a slightly thicker Styrofoam drying block, which is dimensioned for insertion into this cavity, is inserted into the cavity. The drying block has an upper surface with a sticky adhesive so that the drying block sticks and remains adhered to the supported furniture when the remainder of the furniture slide is removed. The slide sheet is further provided with an upturned perimeter edge.
