Abstract

A support rail fastener for detachably fastening a component to a support rail includes: a mounting plate, the mounting plate having at least one attachment element and a guide; a first spring element; and a slider, the slider being displaceable on the guide, the first spring element being brought into a preloaded position by moving the slider on the guide. On the guide and on the slide latching elements are respectively provided which, when the first spring element is preloaded the latching elements are brought into engagement with each other such that the slider engages in a latching position. The support rail fastener in an initial position in which the slider is in the latching position and in which the mounting plate is placed on the support rail by the attachment element is movable along the support rail.

First claim

The invention claimed is:

1. A support rail fastener for detachably fastening a component to a support rail, comprising:
a mounting plate, the mounting plate having at least one attachment element and a guide;
a first spring element; and
a slider, the slider being displaceable on the guide, the first spring element being configured to be brought into a preloaded position by moving the slider on the guide,
wherein on the guide and on the slide latching elements are respectively provided which, when the first spring element is preloaded the latching elements are configured to be brought into engagement with each other such that the slider engages in a latching position,
wherein the support rail fastener in an initial position in which the slider is in the latching position and in which the mounting plate is placed on the support rail by the attachment element is movable along the support rail,
wherein the slider has a first edge and a second edge at a distance therefrom, and a clamping groove formed between the first edge and the second edge,
wherein starting from the initial position, a triggering movement of the slider is induceable by application of a force to the mounting plate in a direction of the support rail, as a result of which triggering movement the engagement between the latching elements is released and the slider is configured to be brought by the restoring force of the first spring element from the latching position into a locking position in which the slider in a region of the clamping groove comes into clamping contact with the support rail and the support rail fastener is fixed in a locking position on the support rail,
wherein the triggering movement comprises a tilting movement of the slider,
wherein the second edge of the slider in the initial position comes into contact with the support rail such that the force applied to the mounting plate in the direction of the support rail is transferred via the second edge to the slider such that the slider makes a tilting movement,
wherein the slider, starting from the locking position of the support rail fastener, is transferrable from the locking position back into the latching position by a movement of the mounting plate in a direction which enables the attachment element to be lifted off the support rail, and
wherein the support rail fastener is configured to be brought back into the initial position in this way.

2. The support rail fastening means according to claim 1 , wherein the first spring element is integrally formed with the slider.

3. The support rail fastener according to claim 1 ,
wherein the latching elements on the guide comprise latching lugs, and
wherein the latching elements on the slider comprise corresponding recesses in which the latching lugs engage in the latching position.

4. The support rail fastener according to claim 1 , wherein the latching elements on the guide comprise elongated holes, and
wherein the latching elements on the slider comprise latching hooks which engage in the elongated holes in the latching position.

5. The support rail fastener according to claim 1 , wherein the slider comprises at least one second spring element, and
wherein the triggering movement of the slider is induceable by an action of force on the mounting plate in the direction of the support rail and against a force of the at least one second spring element.

6. The support rail fastener according to claim 5 , wherein the slider comprises two second spring elements.

7. The support rail fastener according to claim 5 , wherein the at least one second spring element is formed integrally with the slider.

8. The support rail fastener according to claim 5 , wherein the at least one second spring element comprises a leaf spring.

9. The support rail fastener according to claim 1 , wherein the first spring element comprises a helical spring.

10. The support rail fastener according to claim 1 , wherein the guide comprises two guide rails which form a receptacle for the first spring element between them.

11. The support rail fastener according to claim 1 , wherein the slider comprises a spring steel.

12. The support rail fastener according to claim 1 , wherein the slider comprises an opening for insertion of a tool.

13. The support rail fastener according to claim 1 , wherein the mounting plate forms a wall of a housing for receiving the component to be fastened.
