| 摘要 | A green tire support which includes a flexible web supported by and having a longitudinal dimension exceeding the spacing between carrier parts. One of the carrier parts includes a pivoted lever which is shiftable between a first position in which the web is formed into a generally U-shaped tire supporting sling and a second position in which the web is formed into a generally Lshaped configuration. | ||||||
| 权利要求 | 1. A green tire support comprising a frame having a base supporting spaced carrier means, a flexible web supported by and having a longitudinal dimension exceeding the spacing between said carrier means, one of said carrier means including a hand actuated lever member, means pivotally connecting one end of said lever member to said frame wherein said lever member is shiftable about a horizontal pivot axis toward the other of said carrier means into a first position and away from said other carrier means into a second position, means anchoring one end margin of said web to said lever member spaced from its pivot axis, means anchoring the other end margin of said web to the other carrier means, said web having a tire-supporting profile of a generally U-shaped configuration when said lever member is in its first position and a generally L-shaped configuration when said lever is in its second position, and means aligned with said web for contacting said web intermediate the end margins thereof when said lever member is in its second position to raise said web profile to assist in the removal of a tire being supported by said web from said carrier. 2. The support of claim 1 and stop means engagable by said lever member for positioning said lever member in its first position. 3. The support of claim 1 wherein at least one of said anchor means adjustably anchors a web end margin to a said carrier means wherein the curvature of said web can be varied to accommodate tires of various sizes with said lever member in its first position. 4. The support of claim 3 wherein the anchor means associated with said other web end margin adjustably anchors the web to said other carrier means. 5. The support of claim 1 wherein said frame base includes a ramp means constituting said web contacting means and positioned under said lever member. 6. The support of claim 1 and support means in contact with said lever means for urging said lever member into a generally upright position, said support means being yieldable when a tire is set upon said web with said lever arm in said generally upright position to permit said lever arm to shift from said generally upright position into its said first position. 7. A green tire support comprising a frame having a base supporting spaced carrier means, a flexible web supported by and having a longitudinal dimension exceeding the spacing between said carrier means, one of said carrier means including a pivoted lever member shiftable about a pivot axis toward the other of said carrier means into a first position and away from said other of said carrier means into a second position, means anchoring one end margin of said web to said lever member spaced from its pivot axis, means anchoring the other end margin of said web to the other carrier member, said web defining a generally U-shaped tire supporting sling when said lever member is in its first position, support means in contact with said lever member urging said lever member into its second position wherein said web defines a sling which is more open than said first mentioned sling, said support means being yieldable when a tire is set upon said web with said lever member in its second position so as to permit said lever member to shift from its said second position into its said first position. 8. The support of claim 1 and stop means engageable by said lever member for positioning said lever member in an over-center orientation inclined toward said other carrier means when said lever member is in its first position. |
