Definitions

  • the invention relates to a modular system for emergency stop buttons, which contains different functions, such as unlockability, illuminability or unlockability.
  • An emergency stop switch is known from DE 196 07 562 C2, the task of which is then to immediately switch off an electrical machine in an emergency.
  • This emergency can be, for example, an existing danger for the operating personnel, overload or malfunction of the machine.
  • switching devices have a rotary mushroom, which can be rotated in a housing, at least to a limited extent, and is displaceable in the axial direction of the housing.
  • the switching function is carried out by impressing the rotary mushroom, the rotary mushroom being locked when it reaches its pressed-in end position, so that the rotary mushroom cannot be pulled back, for example in order to start the machine again.
  • the emergency stop button is unlocked by turning the rotary mushroom relative to the housing. The turning process can be blocked, for example, by a security lock, so that rotation of the rotary mushroom in the housing is only possible after unlocking the security lock.
  • An emergency stop button is shown and described in DE-GM 93 06 074, in which two radially arranged pins are pressed apart by a spring. The pins rest on a projection which is provided with a bevel arranged at the top and a bevel arranged at the bottom.
  • a clear resistance must be overcome, for example, a certain amount of force must be applied.
  • the emergency stop button can be lifted in again simply by pulling the actuating head in
  • the German patent DE 35 46 059 shows an unlockable emergency stop button with a tubular body, an actuating print head with a recess for a lock cylinder and with an outer jacket, which is made in one piece and is integrally formed on the actuating print head.
  • the plunger is connected to a plunger upper part, which is referred to here as a slide, with a bolt.
  • the push button is firmly attached to the body, while the cylinder can rotate in its recess when the key is present.
  • a push button switch can be found in DE 41 35 208 C2, which is composed of a modular system.
  • a glow lamp is arranged as a luminous element in a base of the switch that can be used for different types of switches and is of uniform design.
  • the top parts of the push button are interchangeable, but the light element in the base is not easily accessible.
  • the object of the invention is to provide an emergency stop button system which is inexpensive to manufacture and store and easily expandable by functions.
  • the modular principle means that fewer different parts are required, which also results in lower storage costs. An expansion of the emergency stop button program is also possible in a simple manner. A particularly cost-effective production and drastic reduction in construction costs and warehousing results because the keys with parts designed for different functions and for certain functions individually designed parts can be assembled in a modular manner.
  • this modular principle allows parts to be used or used several times (for example, a common mushroom head for a lockable key and a key that can be illuminated according to the invention), and on the other hand, the design of the individual parts is not too complicated. For example, a ram sleeve is individually provided with retaining ribs for a lock without having to integrate other functions or features.
  • the emergency stop button system consists of at least a first mushroom head with a closed button surface for use in an emergency lock button that cannot be locked or illuminated
  • the first Mushroom head is individually designed for this function, and consists of a second mushroom head with a key opening, into which a light signal element or a lock can be inserted, the second mushroom head being designed for both functions together and if the emergency stop button system also consists of at least a first one Upper part of the plunger for use in a non-lockable or illuminable emergency stop button, a second upper part of the plunger for use in an emergency stop button with lighting and a third upper part of the plunger for use in a lockable emergency stop button, the upper part of the plunger for the respective function NEN are individually designed if the emergency stop button system consists of a first push button upper part with a first closed bottom with a substantially flat surface, if the emergency stop button system comprises a second push button upper part with
  • Luminous element and the actuating head is arranged, wherein the locking arrangement is designed or arranged in a translucent manner, because on the one hand the lighting element is easily accessible and easily interchangeable and on the other hand the locking function is also fully retained under other possible uses, such as use as a lockable emergency stop button
  • the locking can be implemented particularly easily if the emergency stop button has a button guide which has at least one first guide track running parallel with respect to the longitudinal axis with a locking means which can be immersed in this guide track and which is under spring action, with a first projection in the first guide track is arranged, the first guideway and the first projection are designed such that only a train release is possible, and that the key guide has a second guideway running parallel to the first guideway, in which the locking means can be used, a second in the second guideway Projection is arranged, wherein the second guide track and the second projection are designed such that only a rotational unlocking is possible, the locking means being used either in the first guide track or in the second guide track, the latching means being at least one under spring action g is a standing locking ball, or the latching means are two locking balls resting on the ends of a spring, which can be completely immersed in a tunnel, the tunnel being arranged transversely to the actuating direction, the spring being embedded in the tunnel, and the spring being a
