Abstract

A device for moving an object on a rail that has grid openings, the device having at least one first movement element, at least one first drive element, and at least one engagement element for engaging at least one grid opening. The engagement element is positioned on the first movement element. The first drive element for driving the first movement element is connected to the first movement element, and the first movement element is movably held in such a way that the engagement element is at least in some regions guided along an outside of the device. As a result of this an even force is directly introduced into the rail to prevent the object to be moved by sliding becoming skewed or jammed. Likewise, the device can be supplemented by a motor so moving the object can be carried out automatically, precisely, and quickly.

First claim

The invention claimed is:

1. An apparatus for moving an object on a rail comprising a plurality of grid openings, comprising:
a first movement element comprising a longitudinal element having a first and a second lateral walls;
a first drive element; and
an engagement element for engaging at least one of the plurality of grid openings, the engagement element comprising a plurality of sets, each set comprising a first pair and a second pair, each pair comprising a first and a second cylindrical bodies extending laterally from the first and the second lateral walls, respectively, wherein a first distance between a first pair of a first set and a second pair of a second set is greater than a second distance between the first and second pairs of the first set;
wherein the first drive element is connected to the first movement element for driving the first movement element, and
wherein the first movement element is movably held in such a way that the engagement element is at least in some regions guided along edges of the grid openings.

2. The apparatus of claim 1 , wherein the first movement element is configured as an essentially linear movement element.

3. The apparatus of claim 2 , wherein the first movement element is a closed chain held so as to be movable in circumferential direction.

4. The apparatus of claim 1 , wherein the engagement element is configured as a roller-like body.

5. The apparatus of claim 3 , wherein the first drive element is a chain wheel.

6. The apparatus of claim 1 , further comprising a second movement element and a second drive element, wherein the second drive element is coupled to the first drive element by a first shaft.

7. The apparatus of claim 6 , further comprising a protective tube enclosing the first shaft.

8. The apparatus of claim 7 , further comprising a first pivotably held locking lever for operating one or several locking apparatuses.

9. The apparatus of claim 8 , further comprising a second pivotably held locking lever for operating the one or several locking apparatuses, wherein the second locking lever by way of a second shaft is coupled to the first locking lever in such a way that pivoting of the first locking lever causes corresponding pivoting of the second locking lever.

10. The apparatus of claim 9 , wherein the first shaft or the second shaft is configured as a hollow shaft, and wherein the first shaft, the second shaft and the protective tube are concentrically arranged.

11. The apparatus of claim 10 , wherein the first shaft and second shaft are configured as hollow shafts.

12. The apparatus of claim 6 , wherein said second movement element is at least one second movement element and said second drive element is at least one second drive element.

13. The apparatus of claim 1 , further comprising a drive device for driving the first drive element.

14. The apparatus of claim 13 , wherein the drive device is a motor.

15. The apparatus of claim 13 , wherein for initiating movement of the objects along the rail the drive device is connected to a regulating unit.

16. The apparatus of claim 1 , wherein the first movement element is at least one first movement element, the first drive element is at least one first drive element, and the engagement element is at least one engagement element.

17. A transportation device with at least one rail comprising a plurality of grid openings, at least one object configured to be locked to the rail, and at least one apparatus for moving the object on the rail, the at least one apparatus comprising:
a first movement element comprising a longitudinal element having a first and a second lateral walls;
a first drive element; and
an engagement element for engaging at least one of the plurality of grid openings, the engagement element comprising a plurality of sets, each set comprising a first pair and a second pair, each pair comprising a first and a second cylindrical bodies extending laterally from the first and the second lateral walls, respectively, wherein a first distance between a first pair of a first set and a second pair of a second set is greater than a second distance between the first and second pairs of the first set;
wherein the first drive element is connected to the first movement element for driving the first movement element.

18. An apparatus for moving an object on a rail comprising a plurality of grid openings, comprising:
a first movement element comprising a longitudinal element having a first and a second lateral walls;
a first drive element; and
an engagement element for engaging at least one of the plurality of grid openings, the engagement element comprising a first and a second cylindrical bodies extending laterally from the first and the second lateral walls, respectively, and a connecting member extending between the first and second lateral walls, wherein a first diameter of the first cylindrical body is greater than a second diameter of the connecting member;
wherein the first drive element is connected to the first movement element for driving the first movement element, and
wherein the first movement element is movably held in such a way that the first and second cylindrical bodies are at least in some regions guided along edges of the grid openings in a positive-locking manner in a longitudinal direction of the plurality of grid openings and in a direction transverse to the longitudinal direction.
