Abstract

A floor fixing assembly for releasable fixing of a leg of a frame to a vehicle floor comprises at least one retaining peg which can be fixed to the vehicle floor. The floor fixing assembly furthermore comprises a frame fixing element, which is configured to be connected to the leg of the frame and comprises at least one receiving space for receiving the retaining peg. A clamping device is configured to be introduced into the receiving space of the frame fixing element in order to connect the frame fixing element to the retaining peg by form fit.

First claim

The invention claimed is:

1. A floor fixing assembly for releasable fixing of a leg of a frame to a vehicle floor, comprising:
at least one retaining peg configured to be fixed to the vehicle floor,
a frame fixing element configured to be connected to the leg of the frame and comprises at least one receiving space for receiving the retaining peg, and
a clamping device configured to be introduced into the receiving space of the frame fixing element in order to connect the frame fixing element to the retaining peg by form fit,
wherein the clamping device comprises two clamping split pins which, in a state in which the floor fixing assembly is mounted on the vehicle floor, runs substantially parallel to a longitudinal axis of the frame fixing element and substantially parallel to a plane defined by the vehicle floor, wherein each clamping split pin engages one retaining peg and the frame fixing element, and
wherein the two clamping split pins are connected by a connecting piece that extends in a plane parallel to the plane defined by the vehicle floor and extends in a plane that is perpendicular to the plane defined by the vehicle floor; and
wherein the connecting piece is dimensioned larger than the receiving space.

2. The floor fixing assembly according to claim 1 , wherein the retaining peg is formed and is configured to be fixed to the vehicle floor such that its longitudinal axis, in a state in which the floor fixing assembly is mounted on the vehicle floor and connected to the frame, forms an angle of more than 90° with a main load direction of a load acting in a defined load case on the leg of the frame connected to the frame fixing element.

3. The floor fixing assembly according to claim 1 , wherein the retaining peg is formed and is configured to be fixed to the vehicle floor such that its longitudinal axis, in a state in which the floor fixing assembly is mounted on the vehicle floor and fixed to the frame, and viewed in a direction of a main load direction of a load acting in a defined load case on the leg of the frame connected to the frame fixing element, forms an angle of less than 90 with a plane defined by the vehicle floor.

4. The floor fixing assembly according to claim 1 , wherein the receiving space of the floor fixing assembly is formed such that its longitudinal axis, in a state in which the floor fixing assembly is mounted on the vehicle floor, forms an angle of more than 90° with a main load direction of a load acting in a defined load case on the leg of the frame connected to the frame fixing element.

5. The floor fixing assembly according to claim 1 , wherein the receiving space of the floor fixing assembly is formed such that its longitudinal axis, in a state in which the floor fixing assembly is mounted on the vehicle floor, and viewed in a direction of a main load direction of a load acting in a defined load case on the leg of the frame connected to the frame fixing element, forms an angle of less than 90° with a plane defined by the vehicle floor.

6. The floor fixing assembly according to claim 1 ,
wherein the retaining peg is provided with at least one first groove for receiving one of the clamping split pins,
wherein the first groove extends substantially parallel to the plane defined by the vehicle floor, so that on connection of the frame fixing element to the retaining peg, the respective clamping split pin is guided by the first groove and moved substantially parallel to the plane defined by the vehicle floor.

7. The floor fixing assembly according to claim 6 ,
wherein in a region of its receiving space, the frame fixing element is provided with at least one second groove for receiving one of the clamping split pins,
wherein the second groove extends substantially parallel to the plane defined by the vehicle floor, so that on connection of the frame fixing element to the retaining peg, the respective clamping split pin is guided by the second groove and moved substantially parallel to the plane defined by the vehicle floor.

8. The floor fixing assembly according to claim 1 ,
wherein the frame fixing element is provided with a connecting bore which is configured to receive a connecting element for connecting the leg of the frame to the frame fixing element,
wherein a longitudinal axis of the connecting bore runs substantially parallel or substantially perpendicular to a plane defined by the vehicle floor.

9. The floor fixing assembly according to claim 7 ,
wherein each clamping split pin is provided with a third groove configured to receive the retaining peg in the state in which the floor fixing assembly is mounted on the vehicle floor.

10. The floor fixing assembly according to claim 1 ,
wherein the two clamping split pins
are configured to grip the retaining peg on both sides, or
are configured to cooperate with respective outer faces of two of the retaining pegs arranged next to each other.

11. The floor fixing assembly according to claim 1 , wherein the connecting piece comprises:
a first element which, in a state in which the floor fixing assembly is mounted on the vehicle floor, extends at least one of
between the clamping split pins,
substantially perpendicularly to the clamping split pins, or
substantially parallel to a plane defined by the vehicle floor.

12. The floor fixing assembly according to claim 10 , wherein the connecting piece comprises:
a first element,
two second elements which extend substantially coaxially to each other and towards the outside from respective ends of the clamping split pins, and
two third elements which extend substantially parallel to each other from respective ends of the second elements and connect the second elements to the first element.

13. A frame fixing system, comprising:
a vehicle floor,
a plurality of retaining pegs fixed to the vehicle floor,
a first frame fixing element configured to be connected to a first leg of a frame to be releasably attached to the vehicle floor and comprising at least one receiving space for receiving at least one of the plurality of retaining pegs,
a second frame fixing element configured to be connected to a second leg of the frame to be releasably attached to the vehicle floor and comprising at least one receiving space for receiving at least one of the plurality of retaining pegs,
a first clamping device configured to be introduced into the at least one receiving space of the first frame fixing element in order to connect the first frame fixing element by form fit to at least one of the plurality of retaining pegs, wherein the first clamping device comprises a first clamping split pin which engages at least one of the plurality of retaining pegs, and
a second clamping device configured to be introduced into the at least one receiving space of the second frame fixing element to connect the second frame fixing element by form fit to at least one of the plurality of retaining pegs, wherein the second clamping device comprises a second clamping split pin which engages at least one of the plurality of retaining pegs,
wherein at least one of the first clamping split pin, the second clamping split pin, and the plurality of retaining pegs comprise at least one groove, and
wherein the first clamping split pin and the second clamping split pin are connected by a connecting piece that extends in a plane parallel to a plane defined by the vehicle floor and extends in a plane that is perpendicular to a plane defined by the vehicle floor; and
wherein the connecting piece is dimensioned larger than the at least one receiving space.

14. The frame fixing system according to claim 13 ,
