Claims7
An adjustable tire cart for handling various size and type tires, comprising a frame having a center section and two lateral sections, said lateral sections being spaced apart and extending perpendicularly from the ends of said center section, each of said lateral sections having a perpendicular extension at one end thereof, said perpendicular extensions telescopically engaging said center section to permit adjustment of the spacing between said lateral sections for accommodating various tires, tire lifting means on said frame for engaging and raising or lowering a tire, said tire lifting means including an actuating member mounted on said frame, a pair of pivotable flap members mounted on said lateral sections, and adjustable length linkage connecting said actuating member to said flap members, said adjustable linkage including two lengths of chain, each of said lengths of chain having a first connection connected to one of said flap members and a second connection connected to said acutating member, and at least one of said first and second connections including means for engaging a selected link of the length of chain extending between said connections.
An adjustable tire cart for handling various size and type tires, comprising a frame having a center section and two lateral sections, said lateral sections being spaced apart and extending perpendicularly from the ends of said center section, said lateral sections having perpendicular extensions secured thereto, said extensions telescoping within said center section, said lateral sections being adjustable relative to said center section to vary the spacing between said lateral sections for accommodating various tires;
- means for moving and holding said lateral sections in various positions relative to said center section;
- tire lifting means on said frame for engaging and raising or lowering a tire, said tire lifting means including an actuating member mounted on said frame, a pair of pivotable flap members, one flap member being mounted on each of said lateral sections, adjustable length linkage connecting said actuating member to said flap members;
- tire support means including a pair of support arms, each of said support arms being pivotally mounted at its lower end to a respective one of said lateral sections, said support arms curving inwardly toward each other, each of said support arms having an adjustable bar at its upper end, said bars being parallel to said lateral sections and being adapted to engage the tread of a tire, and a pair of supports adjustably mounted on each of said bars, said supports extending perpendicularly from said bars and being adapted to engage the sidewalls of a tire;
- and a wheel mounted near each of the respective ends of said lateral sections so that the weight of a tire is generally equally distributed on all four of said wheels.
An adjustable tire cart for handling various size and type tires, comprising a frame having a center section and two lateral sections, said lateral sections being spaced apart and extending perpendicularly from said center section, a support arm pivotally mounted at its lower end on each of said lateral sections, said support arms curving inwardly toward each other and having radii of curvature similar to that of tires to be handled by said cart, an adjustable bar on the upper end of each support arm, said bars being parallel to said lateral sections and being adapted to engage the tread of the tire, a pair of supports adjustably mounted on each bar, said supports extending perpendicularly from said bars and being adapted to engage the sidewalls of the tire, and at least one elastic strap detachably connected to one of said pairs of supports and holding said bars against the tread of the tire, and tire lifting means on said frame for engaging and raising or lowering a tire.
