Definitions

  • the present invention relates generally snap-on control buttons of the type set works for example on a machine to ensure a emergency stop which should be continued.
  • the document EP-A-0 386 844 shows a button control according to the preamble of claim 1.
  • buttons commonly called “push fist”
  • a pusher which, for action on any underlying component to which is controlled the machine to be controlled, is mounted mobile axially in the guide body, like a piston, between a retracted position and an advanced position, means hooking, which, interposed on the path of the pusher, to a disengageable retention of the latter in at least one axial direction, are erasable, in the sense that they are capable of releasing the pusher
  • a control member in the general form of mushroom, which, mounted axially movable relative to the body guide, between a standby position and a position recessed service, has a head, for the action of the user, and an axis, for actuating the pusher, elastic return means, which constantly stress the control member towards its extended position waiting, and, intervening between
  • the attachment means act on the pusher in the axial direction from its advanced position, to which it acts on the underlying component, at its position moved back, for which it is moved away from it, and, therefore, in the axial direction from the depressed service position in the standby exit position of the control member.
  • the pusher moves itself in the advanced position, which allows to act on the underlying component to be ordered, by for example switching it from a closed state in an open state, the pusher is caught under the attachment means, and therefore retained by them, it keeps the underlying component open while retaining the control member in the depressed service position.
  • the switching of the closed state in the open state of the underlying component can intervene inadvertently before hooking the pusher, and therefore the control unit.
  • the emergency stop sought is not in this case only temporary, at the expense of security.
  • the present invention generally has for subject a provision to the contrary to ensure advantageously a sustainability of such an emergency stop once this duly established, and leading, moreover, to other benefits.
  • a button kind of control comprising, coaxially, a body guide, by which it is adapted to be mounted on a any support, and which, therefore, is fixed, a push-button, which, for action on any underlying component, is mounted axially movable like a piston in the body of guidance, between a retracted position and an advanced position, attachment means, which, interposed on the path of the pusher, for releasable retention thereof in one direction axial at least, are erasable, a control member, which, mounted movable axially with respect to the guide body, between a standby position and a depressed position of service, has a head, for user action, and a axis, for actuating the pusher, elastic means of reminder, which constantly request the control unit direction from its standby position, in which it is associated with this pusher, on the one hand, elastic means of axial polarization, which are able to stress it in direction of its advanced position, and, on the other hand
  • the pusher is momentarily retained by the attachment means when the control member is the object of a driving action, which prevents it from acting prematurely on the underlying component, and it should be emphasized, on this subject, that these means then intervene on the pusher in one direction axial which, going in this case from its retracted position to its advanced position, and therefore from the standby exit position of the control unit in the depressed service position of this one is the reverse of the previous one.
  • the invention act first on the pusher, in a first axial direction, for retaining this pusher against its displacement towards the underlying component on which it must act, and then on the control organ, in the axial direction opposite to the previous one, for the retention of this member control against elastic return means the soliciting towards its standby position, and, therefore, for locking the assembly in the depressed position on duty.
  • unlocking involves setting using specific means to allow training in relative rotation of the pusher and / or the control member one compared to each other.
  • these means of unlocking which for example comprise a section rod transverse other than circular to be engaged axially in a additional cross section bore provided for this effect in the pusher, can, if desired, be left freely available to the user.
  • This may be, for example, qualified personnel, responsible for controlling, for the benefit of security, whether the affected machine is actually in a state of repair road.
  • any component 10 As schematically illustrated in Figures 1 and 2, it is, overall, to act on any component 10, and, for example, for the emergency stop of a machine, on any electrical component, such as a switch, to cause a change of state of this component 10, that is to say to cause it to switch from one state to another, and, for example, to cause a state of closing in an open state.
