Supporting device
The invention relates to a supporting device, which comprises a larger clearance for the spindle, whereby the foot receiving device should comprise a high level of stability. The foot-receiving device comprises a component, which occludes the inner sleeve. Said component comprises an opening for admitting the spindle, at least one bracing element located on the upper and/or bottom sides thereof, and two opposing bearing points for the support foot.
1. A supporting device for semi-trailers comprising:
an outer sleeve a telescopic inner sleeve;
the spindle for a telescopic inner sleeve; and
a foot-receiving device for attaching a support foot, the foot receiving device connected to a bottom end of the inner sleeve, the foot-receiving device comprising:
a component comprising a plate that occludes the inner sleeve;
an opening in the component plate for penetration of the spindle past a lower end of the inner sleeve;
at least one bracing element at a top or bottom end of the foot-receiving device; and
two opposing bearing points adapted to accommodate the support foot.
2. The supporting device according to claim 1 , wherein the bracing element is arranged within the inner sleeve.
3. The supporting device according to claim 1 , wherein the bracing element extends at least between the bearing points.
4. The supporting device according to claim 1 , wherein the bracing element is a bracing rib.
5. The supporting device according to claim 1 , wherein the bracing element is a bracing rib which has a curved shape and is located around the opening.
6. The supporting device according to claim 1 , wherein the component is said plate having an edge section located outside of the bracing element which is a bracing rib for attachment of the inner sleeve.
7. The supporting device according to claim 1 , wherein the bearing points are arranged on a plane of the component which is said plate.
8. The supporting device according to claim 1 , wherein the bracing element is a circumferential bracing rib, which engages the inner sleeve in a forced fit, is arranged on the top of the component which is said plate and forms a bottom part that constitutes a cover at the bottom of the circumferential bracing rib.
9. A supporting device according to claim 8 , wherein the foot receiving device consists of two laterally reversed halves.
10. A supporting device according to claim 1 , wherein the component comprises a vertically arranged tube whose outside diameter is less than or equal to the inside diameter of the inner sleeve in at least one section.
11. A supporting device according to claim 10 , wherein the tube is a rectangular tube.
12. A supporting device according to claim 10 , wherein the bearing points are attached to the outer surface of the tube.
13. A supporting device according to claim 1 , wherein the opening is closed off by a cover.
14. The supporting device according to claim 2 , wherein the bracing element extends at least between the bearing points.
15. The supporting device according to claim 14 , wherein the component is said plate and the bracing element is a bracing rib.
16. The supporting device according to claim 15 , wherein the bracing rib has a curved shape and is located around the opening.
17. The supporting device according to claim 16 , wherein the plate has an edge section located outside of the bracing rib for attachment of the inner sleeve.
18. The supporting device according to claim 17 , wherein the bearing points are arranged on the plate plane.
19. The supporting device according to claim 18 , wherein a circumferential bracing rib, which engages the inner sleeve in a forced fit, is arranged on the top of the plate and forms a bottom part that constitutes a cover at the bottom of the circumferential bracing rib.
20. A supporting device according to claim 19 , wherein the foot receiving device consists of two laterally reversed halves.
