Definitions

  • the invention relates to a push-button with a housing of the actuating head and body, wherein projecting from the actuating head into the body housing guides in which a spring element supports.
  • Such a pushbutton according to the preamble of claim 1 is in the US2003 / 0226747 A1 disclosed.
  • Such pushbuttons are regularly used for command input at so-called machine / human interfaces. Not only a use for the switching of control currents, but also for power circuits is conceivable by the push-button is used as a trigger for circuit breakers. At this push button high demands are made in terms of life, robustness, sealing of the electrical part against water and dirt as cost-effective and process-reliable manufacturability.
  • Command devices are mounted in control panels, control panels, control cabinet doors or enclosure covers.
  • Command devices are generally modular. That is, they consist of an actuator, a fixing member such as a ring nut or a mounting bracket and one or more switching elements, which are designed as normally closed or normally closed switching elements.
  • the actuator is usually guided from the front through a hole in the dash panel and mounted from behind by means of a fastening part.
  • the switching elements are mechanically fastened with screws, snap hooks or bolts on the actuator or on the fastening part. The electrical connection of the switching elements to the controller via terminals.
  • the signal is generated by opening positive-opening contacts. This means that with an unconfirmed emergency stop device the contacts and so that the associated circuit are closed.
  • the normally closed contact is interrupted by striking the emergency stop actuator, which is located in front of the switchboard, and the system or machine is put into a safe state.
  • the emergency stop command device is no longer functional. That is, in an emergency operation, the contacts are not opened, and thus there is no elimination of the dangerous condition. This can lead to fatal damage to man and machine. Therefore, the secure connection between actuator and switching element is essential.
  • the object of the present invention is to provide a push button which locks when actuated in a safe position.
  • this object is achieved by a push-button with a housing of the actuator head and body, wherein the actuator head in the main body housing guides protrude, in which a spring element superimposed.
  • Essential to the invention is that the housing guides are arranged standing on actuation of the actuating head in operative connection with two locking slides.
  • the emergency stop devices usually have very limited installation space for a locking / unlocking system. It is therefore problematic to develop a system with respect to the life of the required actuation-unlocking forces withstands and remains functional.
  • the main problem is the material wear on the working surfaces of moving parts and the secure locking in the locking positions.
  • two slides are installed with their own springs in a plane parallel to each other, both contribute simultaneously to locking or unlocking.
  • the slides themselves and the mounting parts can be made of different materials and designed differently, for example, transparent with recesses for a light channel.
  • both sliders can lock the emergency stop state with double security. This means that if a slider suffers material breakage, such as spring breakage or material wear, the second slider can still lock the system completely safely.
  • material breakage such as spring breakage or material wear
  • Fig. 1 shows a pushbutton 1 according to the invention with a preferably two-part housing of actuator head 2 and body 3.
  • the actuator head 2 is preferably executed like a mushroom and overlaps the base body 3, wherein the base body 3 is attached via clamping elements 4 on the actuating head 3.
  • the housing guides 5 include a spring element 6 a.
  • the housing guides 5 have at the end insertion bevels 7, which are in operative connection with two locking slides 8 upon actuation of the actuating head.
  • the locking slide 8 are preferably arranged in a plane parallel to each other opposite one another. Upon actuation of the actuating head 2, both locking slides 8 simultaneously change into the locking position, that is to say conversely, that both locking slides 8 likewise have the same position in the unactuated state.
  • Fig. 2 the locking slide 8 are shown, wherein each locking slide 8, a spring 9 is assigned, so that in the case of a spring break still a functional spring 9 remains, which can take the locked state.
  • the 3 and 4 show the position of the locking slide 8 in the unactuated or in the actuated state.
  • the pushbutton according to the invention is characterized in that two slides are moved simultaneously in the actuation case, so that in case of material wear still a functional locking slide remains.
