Abstract: A coupling device for a chair device, such as a wheelchair includes a bracket that is intended to be integrally incorporated in the chair device frame or secured to the frame of the wheelchair. The bracket has an attachment system formed by various elements thereof, which is intended for mating with a corresponding engagement device associated with a lift mechanism or a securing position. The attachment system is intended to mate with the corresponding engagement device to allow the wheelchair to be secured in position and then lifted to or lowered from an elevated position within a transportation vehicle or architectural setting while the wheelchair is occupied. The attachment system is additionally intended to universally mate to a corresponding engagement device for securing of a wheelchair in position.
Abstract: A method for filling a flexible container with a flowable material is provided, including the steps of filling the flexible container, suspending the flexible container, transferring the weight of the flexible container from being suspended to being supported by a support surface, and applying a hoop force to the flexible container to substantially maintain a configuration of the flexible container. The flexible container can be a bag-type container for containing flowable material such as chemicals, food products, agricultural products, and plastic pellets. As the container is lowered from the suspended position to a bottom-supported position, the hoop force is applied around the perimeter as the perimeter changes during transfer of the flexible container from being suspend to being bottom-supported. The hoop force can be applied by stretch wrap. Alternatively, the first flexible container can be lowered into a second flexible container.
