Abstract
A man-powered (e.g. manually pulled or pushed) multipurpose wheeled carrying device with ground clearance for transporting people, animals, equipment and goods over unsurfaced roads or tracks. The carrying device may include a chassis, a front dependent suspension and a rear dependent suspension, wherein each of the dependent suspensions comprises a legged solid axle, a connector, springs, and wheels. The legged solid axles of the dependent suspensions are adapted to keep the chassis at least 6 inches above the ground surface. The dependent suspensions are tiltable around a longitudinal axis of the chassis to keep the chassis leveled while all of the wheels are in contact with the ground, and to provide ground clearance during use.
Claims17
A wheeled stretcher comprising:
- a chassis comprising a supporting platform supported above a plurality of cross members;
- a front dependent suspension and a rear dependent suspension, wherein each of
- said dependent suspensions comprises a substantially inverted U shaped legged solid axle, a connector, springs, and wheels;
- wherein said legged solid axles of said dependent suspensions each comprise legs extending down from a central bar and are adapted to keep said chassis at least 6 inches above the ground surface
- wherein said connectors are attached to the bottoms of said cross members;
- wherein said central bar is pivotally connected to said connector by a pin such that said central bar is located below said connector and pivots relative to said connector about the axis of said pin and
- to keep said chassis leveled while all of said wheels are in contact with the ground wherein said springs are attached between said central bar and said connector on either side of the pin;
- and
- wherein each wheel is supported in a cantilevered fashion at the lower end of one of said legs with a separate axle from the opposite wheel.
A wheeled device comprising:
- a chassis comprising a supporting platform supported above a plurality of cross members and one or more hinges facilitating folding of said chassis;
- a front dependent suspension and a rear dependent suspension, wherein each of said dependent suspensions comprises a substantially inverted U shaped legged solid axle, a connector, springs, and wheels;
- wherein said legged solid axles of said dependent suspensions each comprise legs extending down from a central bar and are adapted to keep said chassis at least 6 inches above the ground surface
- wherein said connectors are attached to the bottoms of said cross members;
- wherein said central bar is pivotally connected to said connector by a pin such that said central bar is located below said connector and pivots relative to said connector about the axis of said pin and
- to keep said chassis leveled while all of said wheels are in contact with the ground wherein said springs are attached between said central bar and said connector on either side of the pin;
- and
- wherein each wheel is supported in a cantilevered fashion at the lower end of one of said legs with a separate axle from the opposite wheel;
- and
- wherein each wheel is supported in a cantilevered fashion at the lower end of one of said legs with a separate axle from the opposite wheel.
