Definitions
- the present invention relates to a padlockable emergency stop button disposed on a mounting wall and comprising a control head, which head is able to act on electrical contacts, on the one hand by moving in translation along a determined axis, from an on position to an off position locked, and on the other hand by turning around this axis to be unlocked so return to the on position (see for example DE 87 04 026 u).
- the invention aims to allow padlocking very simply and so space-saving an emergency stop button unlockable by rotation, of the type described.
- a lug is integral with the control head, preferably a tubular skirt thereof, projecting radially outward, and it is provided a control head locking pull tab, this pull pull being movable in translation in a direction perpendicular to the axis of the emergency stop button, from a locking position to an unlocking position and vice versa, and having an element stop in rotation of the lug as well as at least one passage opening for a padlock.
- the zipper can advantageously be provided with a projection provided for cooperate by abutment with the lug of the skirt so that in the running position it prevents pull out the pull tab and / or in the stop position it prevents the inadvertent ascent of the control head.
- the element for stopping the rotation of the lug is a face of stop provided in a longitudinal bar of the pull tab to lock the lug in rotation, near a window in the bar to let the pin pass rotation. It is more advantageous that the lockout hole is hidden in release position by guide surfaces of the pull tab.
- Figure 1 shows in elevation an emergency stop button in walking position.
- Figure 2 shows the emergency stop button in the locked stop position and blocked.
- Figures 3 and 4 show in section along plane P of Figures 1 and 2 the emergency stop button in the corresponding positions.
- Figure 5 shows in perspective the locking tab associated with the button emergency stop.
- the emergency stop button 10 illustrated in the figures comprises a head control 11 provided with a tubular skirt 12 and a pusher 13 actuated by this head to act on an electrical appliance, not shown, which is housed behind a cover, a partition or other mounting wall such as a cabinet wall 14.
- the button emergency stop 10 is for example fixed to the wall 14 by means of a nut 15.
- the tubular skirt 12 of the emergency stop button has a radial projection outwardly a lug 16 provided to cooperate with a locking pull tab 20.
- the pull tab can be moved in translation in a direction Y normal to X and can take an unlocking position (see figures 1 and 3) and a locking position (see figures 2 and 4) of the emergency stop button.
- the zipper 20 is arranged on the side of the emergency stop button where the lug is located and includes a longitudinal bar 21 provided near a gripping end 22 with a padlocking orifice 23, which can receive at least one padlock; one could of course provide several orifices 23.
- the bar 21 is provided in the middle with a window 24 for passage of the lug 16 and, near this window, an abutment face 25 for the lug. Instead of this window, it is of course possible to provide any other space for the free passage of the lug.
- the window 24 authorizes, in the unlocked position of the zipper, the passage of lug 16 (as shown in dashes in Figure 3), while the face of stop 25 prohibits, in the locking position of the pull tab, the passage of the lug 16 (as shown in dashes in Figure 4).
- the pull tab 20 has guide faces 27a, b and 28a, b which cooperate with walls corresponding guides 31a, b and 32a, b provided in a housing 30; this one is integral with the mounting wall 14 and comes for example from molding with it.
- the housing 30 finally has a shoulder or a projection 33 which extends parallel to the plane P and perpendicular to the direction X; the advance prevents, when the head 11 is out, to extract the pull tab, thanks to its stop against the lug 16 and, when the head 11 is pressed in the stop position and the zipper has been put in position blocking, the raising of the lug, thus contributing to the safety of the device.
- the mounting wall 14 comprises further guide walls 34, 35 which serve on the one hand to guide the zipper, on the other hand to hide the lockout hole 23 of the zipper when it is in its blocking position.
- the bar 21 has a latching element 36 such than a pin, lug, hard point or elastic tab to cooperate with an element complementary latching 37 provided in an adjacent wall, for example in the guide wall 34 or 35, in order to keep the pull tab in the locking position.
- a latching element 36 such than a pin, lug, hard point or elastic tab to cooperate with an element complementary latching 37 provided in an adjacent wall, for example in the guide wall 34 or 35, in order to keep the pull tab in the locking position.
- the holding the pull tab in the unlocked position is ensured by friction of the various guide surfaces and possibly by the presence of a hard point.
- An element elastic return can of course be associated with the pull tab.
- the emergency stop button described works as follows.
- the head of the emergency stop button is out (figure 1). Note that in this state of the zipper cannot be brought from its position in figure 1 to that of Figure 2 because its projection 33 abuts against a side of the lug 16. If the operator wishes to stop the device, he presses on the head 11 (FIG. 2), the lug 16 remaining in the nominal angular position indicated in solid lines in FIGS. 1 and 3. The head then remains locked in this position by its locking means not represented.
