专利汇可以提供Resilient landing gear foot专利检索，专利查询，专利分析的服务。并且A resilient trailer landing gear foot slidably mounted on the lower end of a landing gear leg. The landing gear foot includes a resilient toroid disposed between the lower end of the leg and a ground engaging plate forming a part of the foot for providing resiliency to the foot to absorb shock loading imposed thereon.，下面是Resilient landing gear foot专利的具体信息内容。
1. A landing gear for a vehicle comprising: a leg; a plate member secured to the bottom of said leg; a bracket carried by said leg and movable relative to said leg, said bracket having a wall portion surrounding said leg and extending downwardly below said plate member; a ground engaging member secured to the lower portion of said bracket wall portion; and an elastomer member disposed between said plate member and said ground engaging member, the downward movement of said bracket with respect to said leg being limited by the engagement of said wall portion with said plate member, the upward movement of said bracket with respect to said leg being limited by the amount of compression of said elastomer member between said plate member and ground engaging means when said last mentioned member engages the ground, said elastomer member normally being in an uncompressed state when said bracket wall portion is in engagement with said plate member, said elastomer member having an increasing cross-sectional area as taken in successive planes substantially parallel to the plane of said plate member, the spring rate of said elastomer member increasing as said elastomer member is compressed between said plate member and said ground engaging member.
2. The landing gear as defined in claim 1, wherein said elastomer member is a toroid.
3. The landing gear as defined in claim 1, wherein said elastomer member is substantially cylindrically shaped and is disposed between said plate member and said ground engaging member with its axis of elongation substantially parallel to the axis of elongation of said leg.
4. The landing gear as defined in claim 3, wherein said elastomer member is chamferred at one end around its outer edge.
5. The landing gear as defined in claim 4, wherein said elastomer member has an aperture formed therethrough with its aXis of elongation substantially parallel to the axis of elongation of said leg.
6. The landing gear as defined in claim 5, wherein said aperture includes a cylindrical portion and a cone shaped portion increasing the diameter of said aperture at the chamferred end of said elastomer member.
7. The landing gear as defined in claim 1, wherein a portion of said plate member extends laterally beyond said leg, and said bracket wall portion engages said laterally extending portion of said plate member for limiting the downward movement of said bracket with respect to said leg.
8. The landing gear as defined in claim 1, wherein said leg includes a tubular portion forming its lower end, and said plate member is disc shaped with a diameter larger than the outer diameter of said leg.
9. The landing gear as defined in claim 8, wherein said bracket includes a tubular portion having its lower end secured to said ground engaging member and an annular flange extending inwardly from the upper end of said tubular portion, said plate member being disposed within said bracket and engaging said flange for limiting the downward movement of said bracket with respect to said leg.
10. A landing gear for a vehicle comprising: a leg; a plate member secured to the bottom of said leg; a bracket movably secured to the bottom portion of said leg and extending downwardly past said plate; a ground engaging member secured to the lower portion of said bracket; and a resilient member having a substantially cylindrical shape and chamfered at one end around its outer edge and having an aperture formed therethrough with its axis of elongation substantially parallel to the axis of elongation of said leg, said aperture including a cylindrical portion and a cone-shaped portion increasing the diameter of said aperture at the chamfered end of said resilient member, the spring rate of said resilient member increasing as said resilient member is compressed between said plate and said ground engaging member.
