Abstract: A pull-behind carriage has an auxiliary wheel mounted on a reconfigurable drawbar. When the pull-behind carriage is converted to a push carriage, the drawbar is folded so that the auxiliary wheel is positioned on the ground to act as an extra, supporting wheel. Joints in the drawbar are palm operated and can be rotated without continuing to hold the joint. The drawbar may also serve to move the axle of the main wheels backwards when the carriage is converted from the pull-behind mode to the push mode.

Abstract: A harness for pulling a carriage by a person is attached to a pulling assembly, which includes a rigid drawbar coupled to the carriage and a cantilevered member coupled to the forward end of the drawbar and to the harness. The cantilevered member partially isolates cyclical motion of the person from the drawbar, and may be a spring, a sprung rigid member or a rigid member controlled by an electronic servo.

Abstract: A harness for pulling a carriage includes a waistband and a plurality of pressure-distributing plates. A pulling assembly for coupling the harness to the carriage includes a drawbar coupled to the carriage and a spring coupled to the drawbar and to the harness. A length and an angle of the spring are adjustable.

Abstract: A vehicle is equipped with an automated device for covering the windows of the vehicle. The device comprises a collection container, a plurality of the extensions attached to the collection container, a motor attached to the collection container to rotate the collection container, and a covering attached to the plurality of extensions and sized to cover the windows of the vehicle. The rotation of the collection container extends and retracts the plurality of extensions which results in the deployment of the covering over the windows of the vehicle and the collection of the covering from the windows of the vehicle. In a preferred embodiment, the plurality of extensions comprises malleable metal strips with eyelets at the end of the metal strips. The eyelets and the metal strips are positioned within sleeves or channels which are made integral to the covering. The covering includes a reflective fabric that is substantially opaque to sunlight.
