  • Patent number: 8857848
    Abstract: A collapsible vehicle trailer comprises a detachable lightweight enclosure (1), consisting of flexible, collapsible walls (21) and floor (22). The enclosure has two or more support frame members (2) integral to the structure of the enclosure. The support frame members are integrated into the structure of the enclosure by virtue of horizontal loops (3) and vertical loops (4). The enclosure is detachably connected to the rigid frame of the vehicle trailer, by means of the integral support frame members and the front transverse frame member (5) and the rear transverse frame member (6). The enclosure becomes a self supporting, freestanding structure when detached from the trailer frame. The enclosure also acts as a storage bag for the constituent components of the collapsed trailer frame.

  • Patent number: 6715775
    Abstract: A forward dumping, two-wheeled barrow possessing the means to prevent inadvertent rearward dumping and/or injury to the operator is herein disclosed. The primary subassemblies of the forward dumping, two-wheeled barrow include a frame assembly, a wheel assembly, and the cargo receptacle. The frame assembly preferably includes an adjustable length handle assembly and a safety/spill prevention bracket located somewhere between the wheels and the end of the handle assembly. This novel feature prevents potential injury to the operator or nearby individuals (e.g. to the feet) and avoids the problem of emptying all or some of the receptacle's contents in an unintended location. In addition, the safety bracket provides a stable rearward loading position with minimal risk of tipping and/or rolling. The ergonomically designed barrow is fabricated of a variety of strong, lightweight materials (e.g. aluminum, reinforced plastics) to provide a high-strength-to-weight ratio.

  • Patent number: 6508478
    Abstract: An auxiliary wheeled frame for wheelbarrows having a lateral beam being attached to the legs of a typical wheelbarrow and having attached at a bottom outer end thereof a plurality of pivotable, rotating wheels one each attached at each exterior end of the lateral beam exterior to a position where the legs of a typical wheelbarrow normally rest on the ground. A plurality of braces are provided with the braces being either removably or permanently secured one each to an upper side of said lateral beam immediately interior of each rotating wheel and to one each of the legs of a typical wheelbarrow. A horizontal cross bar is provided with the horizontal cross bar being secured between interior portions of each of the legs of a typical wheelbarrow. The rotating wheels may be removably attached, may have brake means, and may be castor-type wheels. A plurality of second diagonal bars may be secured between interior portions of each of the legs of a typical wheelbarrow. The lateral beam may have a toolbox.

  • Patent number: 6474007
    Abstract: A snow removing vehicle has a vehicle body frame and a snow removing member connected directly to a front part of the vehicle body frame for removing snow from a ground surface. The snow removing member has a generally arc-shaped portion curved concavely rearward from the front part of the vehicle body frame. A single wheel axle is rotatably mounted on the vehicle body frame and is disposed in a widthwise central portion thereof so that the vehicle body frame is pivotally movable about the single wheel axle. At least one wheel is mounted on the single wheel axle. A pair of operational handles are connected directly to a rear part of the vehicle body frame so that upward and downward movement of the right and left operational handles relative to the ground surface pivots the vehicle body frame relative to the single wheel axle.

  • Patent number: 6446989
    Abstract: A wheelbarrow includes a load carrying bin, a frame structure, a number of wheels, and a closed loop pivotal handle. The handle is attached near the rear of the wheelbarrow on a pivoting axis so that the user may adjust the height of the handle. The handle may be attached with two threaded pins having knobs at one end so a user may fix the handle at one particular height, may leave the handle entirely adjustable, or may remove the handle entirely for convenient storage of the device. The wheels are placed to provide complete support for the load and may include vertical swivel axes to make moving the wheelbarrow easier.

  • Patent number: 6390496
    Abstract: In a wheel barrow having a load carrying container disposed between a rotatable wheel and a handle, an adapter apparatus is disclosed for assisting transportation of the wheelbarrow. The adapter apparatus includes a frame having a first and a second end and an axle having a first and a second side. The axle extends through the frame and the rotatable wheel such that the rotatable wheel rotates about the axle. Additionally, the axle pivotally supports the wheel barrow such that pivotal movement of the wheel barrow about the axle and relative to the frame is permitted. A rotatable device is secured to the frame so that the container is disposed between the axle and the rotatable device. The arrangement is such that in a first mode of operation of the apparatus, the wheel barrow is supported by the frame and is transported on the rotatable wheel and the rotatable device for transportation of the load disposed within the container.
