Variable outer diameter wheel for vehicles

A vehicle having variable outer diameter wheels, each wheel comprising:

• a generally cylindrical supporting part having a cylindrical wall in which are formed a plurality of penetrating holes;
• a plurality of diaphragms disposed adjacent to and inward of said penetrating holes;
• sliders disposed in said penetrating holes, said sliders adapted to slide in said penetrating holes and form overlapping wheel peripheral parts;
• and moved through pressure exerted on said diaphragms by fluid supplied inside said supporting part causing the outer diameter of said variable outer diameter wheel to enlarge;
• and
• an axle for coupling said wheel to said vehicle.

A vehicle having variable outer diameter wheels comprising:

• sealing parts which have diaphragms fitted against a plurality of penetrating holes inside a pipe having said penetrating holes;
• sliders forming wheel peripheral parts fitted into said penetrating holes so that said sliders can slide in said penetrating holes;
• said sealing parts and said pipe held in air-tight relationship between side plates provided on both ends of said pipe;
• said sliders are moved by fluid introduced into said pipe in the direction that the outer diameters of said variable outer diameter wheels enlarge;
• and
• a plurality of axles, each for coupling a respective one of said wheels to said vehicle.

A variable outer diameter wheel comprising:

• a supporting part having the shape of a pipe or drum, said supporting part having a fluid supplying passage and a plurality of penetrating holes disposed radially and equidistant around a side wall of said supporting part and, said supporting part connected to said fluid supplying passage;
• a slider disposed in each of said penetrating holes in said supporting part, said sliders adapted to slide in said penetrating holes and form overwheel peripheral parts;
• said sliders moved by fluid supplied into said fluid supply passage to move said sliders in a direction so that the outer diameter of said variable outer diameter wheel enlarges;
• and
• a tire selected from the group comprising a tubeless tire or tire having a rubber inner tube mounted on said supporting part.

A variable outer diameter wheel comprising:

• a supporting part having a plurality of penetrating holes disposed radially and equidistant around an outer cylindrical face surface of a cylindrical trunk of said supporting part with diaphragms facing said penetrating holes;
• sliders disposed in said penetrating holes, said sliders adapted to slide in said penetrating hole, and form overlapping wheel peripheral parts;
• said sliders moved in said holes perpendicular to the cylindrical face of said supporting part by said diaphragm facing said penetrating holes;
• said sliders moved by fluid supplied inside said supporting part in a direction so that the outer diameter of said variable outer diameter wheel enlarges;
• and
• a tire selected from the group consisting of a tubeless tire or a tire having a rubber inner tube attached around the cylindrical face of said supporting part.

A variable outer diameter wheel for use with a vehicle comprising:

• sealing parts having diaphragms facing a plurality of penetrating holes disposed inside a supporting pipe having penetrating holes;
• sliders forming wheel peripheral parts are disposed in said penetrating holes so that said sliders can slide in said penetrating holes;
• said sealing parts and said pipe are held in air-tight relationship between side plates provided on both ends of said pipe;
• wherein
• said sliders are moved by fluid introduced into said pipe to move said sliders outwardly from said holes to increase the diameter of said variable outer diameter wheel;
• and
• an axle for coupling said wheel to said vehicle.
