| 摘要 | A green tire carrier having a wheeled frame providing support at three levels thereof for tire carrying sling members, each sling member being adjustable between several operative positions and an inoperative position accommodating access to tires on the sling therebelow. A step is carried by the frame along at least one side thereof adjacent and below the lowermost sling support and at an elevation to facilitate application of tires to and removal of tires from the upper sling by a workman of average height while standing on the step. The step may be shiftable between operative position projecting laterally from the frame and a retracted position. | ||||||
| 权利要求 | 1. A green tire carrier comprising a wheel supported rigid frame having a base portion and superstructure. sling supports carried by said frame at three levels thereof, tire supporting slings carried by said sliNg supports, said uppermost sling supports being located at an elevation above the reach of a workman of average height, and a step member carried by said frame at one side thereof below the level of and substantially parallel to the sling supports of the lowermost slings and adapted to support a workman in position to apply tires to and remove tires from the uppermost sling means. 2. A green tire carrier as defined in claim 1, wherein said slings are adjustable on said sling supports to accommodate tires of a range of different sizes, and are spaced vertically to accommodate tires of the largest size in said range with slight clearance, and means on said superstructure for selectively laterally positioning the two upper slings remote from the side of the frame which carries said step and each clear of tires in the next lower sling. 3. A green tire carrier as defined in claim 1, wherein said step member is shiftable between a substantially horizontal operative position projecting laterally from said frame and a position retracted within the outline of said frame. 4. A green tire carrier as defined in claim 3, wherein said step member is pivoted to said frame for support by said frame in its horizontal operative position, said step being substantially vertically positioned when retracted. 5. A green tire carrier as defined in claim 4, and spring means normally urging said step means to retracted position. 6. A green tire carrier as defined in claim 4, wherein said frame carries adjacent each end of said step member a pair of vertically spaced rigid pins and said step member includes a part at each end thereof having a substantially L-shaped aperture receiving said pins and accommodating swinging of said step between and limiting swinging at said horizontal and vertical positions. 7. A green tire carrier as defined in claim 3, wherein horizontal guide means are carried by said frame and said step is slidable in said guide means. 8. A green tire carrier as defined in claim 7, and spring detent and recess means for releasably maintaining said step in selected position. |
