Abstract

A quick-release mounting apparatus for mounting a panel instrument to a mounting surface or support. The mounting apparatus comprises a frame to be mounted to the mounting support. A slide bar is slidably mounted to the frame and is slidable between a locked position and an unlocked position. The slide bar has a mounting hole configured to receive a mounting pin projecting from the back surface of the panel instrument. The mounting hole locks the mounting pin within the mounting hole in the locked position and allows the mounting pin to be removed from the mounting hole in the unlocked position. A cam is rotatably mounted to the frame and couples the slide bar to an actuator configured to rotate the cam between a locking position and an unlocking position. The actuator has a biasing device which biases the cam toward the locking position.

First claim

What is claimed is:

1. An apparatus for mounting a panel instrument to a mounting support, the panel instrument having a back surface with mounting pins projecting therefrom, the apparatus comprising:
a frame configured to be mounted to the mounting support;
a slide bar slidably mounted to the frame such that the slide bar is slidable between a locked position and an unlocked position, the slide bar having a mounting hole configured to receive one of said mounting pins projecting from the back surface of the panel instrument, the mounting hole configured to lock the one of said mounting pins within the mounting hole in the locked position and to allow the one of said mounting pins to be removed from the mounting hole in the unlocked position;
a cam rotatably mounted to the frame such that the cam may be rotated relative to the frame in a first rotational direction to a locking position and a second rotational direction opposite the first rotational direction to an unlocking position;
a link coupling the slide bar to the cam such that rotation of the cam in the first rotational direction forces the slide bar toward the locked position, and rotation of the cam in the second rotational direction forces the slide bar toward the unlocked position; and
an actuator coupled to the cam and configured to rotate the cam between the locking position and the unlocking position, the actuator having a biasing device which biases the cam in the first rotational direction toward the locking position.

2. The apparatus of claim 1 , wherein the actuator comprises a tool interface for receiving a tool for manipulating the actuator to rotate the cam.

3. The apparatus of claim 1 , wherein the cam comprises a structure selected from the group consisting of a coupling disc, a coupling rod, a coupling link, and a coupling plate.

4. The apparatus of claim 1 , wherein the actuator comprises:
a pull bar slidably mounted to the frame;
a linkage coupling the pull bar to the cam;
the biasing device comprises a biasing spring received on the pull bar, a first end of the biasing spring bearing against a spring stop fixed to the frame and a second end of the biasing spring bearing against a stop on the pull bar such that the biasing spring biases the pull bar thereby causing the pull bar to exert a force on the linkage causing the linkage to bias the cam in the first rotational direction;
a tool interface coupled to the pull bar, the tool interface configured to receive a tool for moving the pull bar which in turn moves the linkage causing the linkage to rotate the cam.

5. The apparatus of claim 1 , wherein:
the one of said mounting pins includes a groove, and the mounting hole comprises a locking edge configured to be received in the groove of the one of said mounting pins in the locked position of the slide bar such that when the one of said mounting pins is inserted into the mounting hole to a locking depth, the biasing of the biasing device forces the first locking edge into the groove and the biasing of the biasing device biases the locking edge to remain in the groove thereby locking the one of said mounting pins in place within the mounting hole such that the one of said mounting pins cannot be removed except by sliding the slide bar to the unlocked position.

6. The apparatus of claim 5 , wherein the locking edge is further configured such that as the one of said mounting pins is inserted into the mounting hole, the one of said mounting pins pushes against the locking edge thereby pushing the slide bar toward the unlocked position.

7. The apparatus of claim 1 , wherein:
the slide bar comprises another mounting hole configured to receive another mounting pin projecting from the back surface of the panel instrument, the another mounting hole configured to lock the another mounting pin within the another mounting hole in the locked position of the slide bar and to allow the another mounting pin to be removed from the another mounting hole in the unlocked position of the slide bar.

8. The apparatus of claim 1 , further comprising:
another slide bar slidably mounted to the frame such that the another slide bar is slidable between a locked position and an unlocked position, the another slide bar having a another mounting hole configured to receive an another mounting pin projecting from the back surface of the panel instrument, the another mounting hole configured to lock the another mounting pin within the another mounting hole in the locked position and to allow the another mounting pin to be removed from the another mounting hole in the unlocked position; and
an another link coupling the another slide bar to the cam such that rotation of the cam in the first rotational direction forces the another slide bar toward the locked position, and rotation of the cam in the second rotational direction forces the another slide bar toward the unlocked position.

9. The apparatus of claim 8 , wherein the cam is positioned between the slide bars.

10. A mounting system for a panel instrument having a back surface, the system comprising:
a first mounting apparatus including:
a first frame configured to be mounted to the back surface of the panel instrument; and
a mounting pin projecting from the first frame;

a second mounting apparatus configured to releasably attach to the first mounting apparatus, the second mounting apparatus including:
a second frame configured to be mounted to the mounting support;
a slide bar slidably mounted to the second frame such that the slide bar is slidable between a locked position and an unlocked position, the slide bar having a mounting hole configured to receive the mounting pin, the mounting hole configured to lock the mounting pin within the mounting hole in the locked position and to allow the mounting pin to be removed from the mounting hole in the unlocked position;

a cam rotatably mounted to the second frame such that the coupling member may be rotated relative to the frame in a first rotational direction to a locking position and a second rotational direction opposite the first rotational direction to an unlocking position;
a link coupling the slide bar to the cam such that rotation of the cam in the first rotational direction drives the slide bar toward the locked position, and rotation of the cam in the second rotational direction drives the first slide bar toward the unlocked position; and
an actuator coupled to the cam and configured to rotate the cam between the locking position and the unlocking position, the actuator having a biasing device which biases the cam in the first rotational direction toward the locking position.

11. The mounting system of claim 10 , wherein the actuator includes:
a pull bar slidably mounted to the second frame;
a linkage coupling the pull bar to the cam; and
wherein the biasing device comprises a biasing spring received on the pull bar, a first end of the biasing spring bearing against a spring stop fixed to the second frame and a second end of the biasing spring bearing against a stop on the pull bar such that the biasing spring biases the pull bar thereby causing the pull bar to exert a force on the linkage causing the linkage to bias the cam in the first rotational direction;
a tool interface coupled to the pull bar, the tool interface configured to receive a tool for moving the pull bar which in turn moves the linkage causing the linkage to rotate the cam.

12. The mounting system of claim 10 , wherein the cam comprises a structure selected from the group consisting of a coupling disc, a coupling rod, a coupling link, and a coupling plate.

13. The mounting system of claim 10 , wherein:
the mounti
