| 摘要 | A rectangular supporting frame, which can be mounted in a vehicle, has pairs of rollers protruding from its ends near the corners. A rectangular load carrier frame has transverse plates with pairs of substantially elliptical guide track slots in which the rollers ride. The slots are cut so that they form parts of ellipses having their major axes tilted from the planes of the frames and intersect to form an oblique angle and so that lines perpendicular to those axes intersect above the frames in a vertical plane which contains the center of gravity when the frames are at rest. In another embodiment the rollers are mounted on the load carrier frame and the guide slot plates are mounted on the supporting frame. Torsion bars are provided to prevent torsional flexing of the carrier frame. In a third embodiment linkages are provided between the two frames so that relative motion between them is similar to that with the slots. | ||||||
| 权利要求 | 1. An apparatus for supporting a load to be subjected to translational forces comprising the combination of a supporting frame; a load carrier; first and second support members both attached to one end of said load carrier and said supporting frame, said members being spaced apart in the direction of the forces; first and second means mounted on the other one of said load carrier and said supporting frame for supporting said load carrier and for guiding said first and second support members, respectively, along separate and different substantially elliptical path of transverse movement in response to application of the forces, said paths of transverse movement being substantially symmetrical with respect to a vertical plane containing the center of gravity of the load and load carrier when the load carrier is at rest, the major axes of the ellipses containing said paths forming an oblique angle such that the axes perpendicular to said major axes intersect said plane above said center of gravity; and third and fourth support members and third and fourth means for supporting and guiding at the other end of said carrier. 2. An apparatus according to claim 1 wherein said support members comprise first and second rollers mounted for rotation on said load carrier; and said first and second means mounted on the other one of said load carrier and said frame comprise first and second substantially elliptical guide tracks, and means for supporting said guide tracks on said supporting frame. 3. An apparatus according to claim 1 wherein said support members comprise first and second rollers fixedly mounted for rotation on said supporting frame; and said first and second means comprise first and second substantially elliptical guide tracks, and means for mounting said guide tracks on said load carrier. 4. An apparatus according to claim 1 wherein said first and second support members comprise first and second pivot axles and means for mounting said pivot axles on said load carrier; and wherein each of said first and second means for supporting said load carrier and for guiding said support members comprises a linkage having a first link pivotally connected at one end to a point on said supporting frame, said first link being substantially horizontal when the forces are not applied; a second link pivotally connected at one end to said supporting frame at a higher point than the point of pivotal connection of said first link; and a third link pivotally connected at one end to said load carrier, at the other end to the other end of said first link, and at a midpoint of said third link to the other end of said second link, said first and third links being of approximately equal length and said second link being approximately half the length of either; and wherein said first links extend away from each other from their points of connection to said frame and wherein said second links diverge downwardly from their points of connection to said carrier when the forces are not applied. 5. An apparatus according to claim 1 wherein said load carrier comprises an elongated frame having said first and second support members attached thereto at one end thereof; said carrier further comprising a torsion stabilizer interconnecting said support members on at least one side of said carrier. |
