Abstract
A protective bumper device formed of: a pair of cylinders, each having outer wall surfaces which include on each of the cylinders a first sidewall surface extending in the lengthwise direction, the cylinders each having a central longitudinal axis, the cylinders being positionable with the first wall surfaces of the two cylinders respectively spaced apart and in facing relationship, a web of sheet material having top and bottom edges and opposite side edges, each of the side edges fixed to one of the first sidewall surfaces of the cylinders respectively.
Claims21
A protective bumper device comprising:
- a. a pair of inflatable tubes made of flexible sheet material, each tube having outer wall surfaces which include on each of said tubes a first sidewall surface extending in the lengthwise direction,
- said tubes each having a central longitudinal axis, said tubes being positionable with said first wall surfaces of said two tubes respectively spaced apart and in facing relationship,
- b. a web of sheet material having top and bottom edges and opposite side edges, each of said side edges fixed to one of said first sidewall surfaces of said tubes respectively, and
- c. valve means coupled to said tubes for inflation and deflation of said tubes.
A protective device for a person's lumbar back area, where the person's back defines a contact surface, a portion of which is wounded and is protected from pressure contact, comprising:
- a. a pair of inflatable tubes having outside diameter D when inflated and length L,
- b. a web of sheet material having length and having width terminating in opposite side edges,
- c. each of said tubes secured along its length to one of said side edges of said web and extending generally parallel to the length of said web,
- d. said web being extendible as a first plane between said tubes where said bottom surfaces of said tubes define a second plane spaced apart from said first plane, and
- e. valve means for inflating and deflating each of said tubes.
A protection device for a person's lumbar back area, where the person's back defines a contact surface, a portion of which is wounded and is to be protected from contact, comprising:
- a. a top sheet having length and width,
- b. a bottom sheet having generally the same dimensions,
- c. the opposite side edges being heat sealed together, a heat seal line parallel to and spaced from each of said side edges, thus defining a tube between said side edge and said heat seal line, said heat seal lines being spaced from each other, the ends of each tube being closed, and
- d. valve means for inflating and deflating each of said tubes.
A bumper device comprising an inflatable tube defining a closed loop surrounding a space, said tube made of flexible sheet material, a web extending across at least a part of said space and secured to inner wall surfaces of said loop, and valve means coupled to said tube for inflation and deflation of said tube.
A bumper device comprising an elongated cylinder formed into a closed loop surrounding a space and a web extending across at least a part of said space and secured to inner wall surfaces of said loop.
