Abstract: A sandbagging attachment to a tiltable dolly for filling bags with scoopable materials such as sand without use of shovels and for subsequent transportation of the filled bags to the destination by using the same dolly. The attachment contains a connection member for connecting the attachment to the dolly and a scoop with a through passage for a material to be scooped. The connection member rotationally supports a scoop that can be turned between a scooping position for filling a bag and a transportation position, at which the filled bag can be transported by the dolly to the destination. The attachment eliminates a need for a special sandbagging equipment. All aforementioned operations are accomplished without the use of manual labor, except for transporting the dolly and removing the filled bag from the dolly.

Abstract: Provided is a one-wheel drop-floor trailer for towing motorcycles. The trailer is characterized by a provision of a two-pivot link having one pivot as a part of a universal joint of a trailer hitch and another pivot as an axis for rotational connection to a main tow bar frame. The two-pivot link allows the plane-parallel movements of the trailer platform in a vertical direction between the working, i.e., transport position, and the floor or ground level for loading/unloading the bicycle.

Abstract: A composite protective helmet comprises two or more separable and mutually connectable parts that can be interconnected by L-shaped projections on one of the parts and L-shaped recesses on a mating part so that during assembly the L-shaped projections are inserted into the mating recesses and the separable parts are interconnected by shifting one part relative to the other so that elements of the L-shaped projections that are parallel to the mating end faces are inserted into respective parts of the recesses, and then the separable parts of the helmet are locked in the assembled state, e.g., by hooks on one of the parts and a hook-engaging ferrule on the other of the separable parts. The advantage of the composite protection helmet is that after the parts are separated, they can be stored in a relatively small space, e.g., in a top box attachable to the luggage rack of a motorcycle.

Abstract: Proposed is a wheeled drop-floor trailer that has a U-shaped frame with two articulated linkages pivotally installed on the sides of the U-shaped frame and suspension rods that pivotally support the drop floor in a freely hanging condition. On the side of the trailer opposite the loading side the articulated linkages are interconnected by a cross bar, which is connected to a drive mechanism, e.g., to a winch, via a cable. When the articulated linkages are inclined toward the loading side, the drop floor descends to the ground under its own weight and, after the cargo is loaded onto the drop floor, the latter is raised by pulling the linkages with the use of the winch via the cable and the cross bar in the direction opposite the loading side.
