Definitions
- An additional object is a mechanism of this type which can take three stable positions, namely "stop”, “on”, “triggered” and a transient reset position.
- this object and these objects, as well as others which will appear subsequently, are achieved by means of a mechanism of the aforementioned type, characterized in that it comprises at least one lever which acts on at least one push-button block for actuating the switches and which is articulated around a fixed axis, this lever comprising a bearing surface, preferably constituted by a roller, applied to the profile of a cam by elastic means, means being designed to move this cam from a locked position for automatic operation where it keeps the lever away from the push block, thereby authorizing the closing of the switches, towards a triggered position where the lever acts on the push block to maintain the switches in the open position.
- this button can be secured to a finger capable of pushing the cam towards its locking position, position in which it engages with a trigger and is locked in rotation.
- the cam can then be released by actuating this trigger by means of one or more fault detection relays.
- the mechanism according to the invention comprises a cleat which is pivotally mounted on a fixed axis against a spring and which can be blocked by two triggers each of which can be unlocked by a detection relay default.
- One of these triggers can be that which also blocks the main S-cam specified above and which is controlled by a fault detection relay, while the other is controlled by another fault detection relay, a link may or may not exist between these two triggers.
- the trigger cam 7 has substantially the shape of an S mounted in its center on the axis 8, so that its width, taken along a fixed line contained in the plane of Figure 1, can go from a small value ( Figure 4) where the rollers 6 are close to each other, at a higher value ( Figures 2, 3 to 5) by moving away from each other and by pivoting outwards the branches which carry them Z-shaped levers, 4 against the springs 9.
- Figures 2, 3 to 5 a higher value
- a cleat 21 is articulated on a pivot 22 parallel to the axis 8, at a distance therefrom and against a return spring 23. It has a finger 24 which is directed towards the axis 8 and which bears, under the effect of the spring 23, on the cam 14.
- the latter successively comprises: a heel 25 against which the finger 24 abuts to block the axis 8 in an angular position corresponding to the "stop" position "against the action of the spring 11, and a circular portion allowing a quarter-turn rotation of the axis 8 in the clockwise direction from the" off "position.
- the recess 44 of the lever 37 and its looped spring 46 serve to allow correct hooking in the "automatic" position without interfering with the triggering: during operation of the button 10 towards the "stop” position, the notch 35 of the cam 16 biases downward the finger 36 held in abutment by the spring 39, and this, until exhausted, tilting of the lever 37 and opening of the switch 42.
- the S-cam, 7 can rotate under the effect of the rollers 6 on which the springs act 9.
- the rollers come together, which causes the free ends of the levers in Z, 4 to move towards the blocks- pushers 2 and to open the switches 1.
- the switch 42 opens, which removes the supply of electromagnets A and B which also press push-buttons 2 to open switches 1.
- the device which has just been described in its application to a reversing contactor-limiter device can be applied to a simple contactor-limiter, by replacing the push-buttons 2a and 2b of FIG. 1 with a single push-button 2 shown on Figure 6 on which act the free ends of the two levers in Z, 4a and 4b.
