The the emergency stop button is unlocked by turning the rotary mushroom relative to Casing. The turning process can be blocked, for example, by a security lock be so that a rotation of the rotary mushroom in the housing only after unlocking of the security lock is possible.

From DE 32 37 589 A1 illuminated pushbuttons are known, which have a housing and one against have a spring force long displaceable hollow plunger, one of the Housing attached light source is arranged, which is on the plunger face located translucent button illuminated from the inside. In particular, with With the help of a collecting lens arranged on the plunger, one contained in the tactile surface Focus screen illuminated with a converging light beam. The illuminated button cannot be used as an emergency stop button because e.g. B. the Locking function is missing. It is also not possible to convert to one.

A push button switch can be found in DE 41 35 208 C2, which is modular is composed. In a usable for different switch types and Uniformly designed base of the switch is a glow lamp Luminous element arranged. The tops of the key switch are interchangeable, however the light element in the base is not easily accessible.  

DE 93 06 074 U1 is an emergency stop button according to the preamble of claim 1 shown and described. Two radially arranged pins are held by a spring pressed apart. The pins rest on a protrusion, the one on top arranged slope and a slope arranged below is provided. At the A clear resistance must be overcome by pressing the emergency stop button. for example, you have to hit it with a certain force. The emergency stop The button can be moved in by simply pulling up the actuating head Unlock axis direction, whereby resistance must be overcome here too.

Planning and warehousing is simplified if the lighting element in one Base body snap-in functional element is arranged, the z. B. against an in the same way snap-in switching element is interchangeable.

A special low-cost production and drastic reduction in Warehousing results when the emergency stop button comes from an emergency stop button system is built up, with the built up from the emergency stop button system with for different functions jointly trained parts and for certain Functions of individually designed parts can be put together modularly. This modular principle means that parts can be used multiple times or insert (e.g. a common mushroom top for an unlockable button and a illuminable button according to the invention), on the other hand, the constructive training of the parts not too complicated. For example, a plunger sleeve is individually included Provide holding ribs for a lock, without other functions or features to have to integrate.

A particularly affordable modular system that is used most frequently in practice Integrated emergency stop buttons, results when the emergency stop button system is at least off a first mushroom top with a closed button surface for use in a there is no lockable or illuminated emergency stop button, the first Mushroom top is individually designed for this function, and from a second Mushroom top with a key opening, optionally in the Light signal element or a lock can be used, the second mushroom top for both functions are trained together and if the emergency stop continues Key system at least from a first plunger upper part for use in a neither lockable nor illuminated emergency stop button, a second Tappet upper part for use in an emergency stop button with lighting and one  third plunger upper part for use in an unlockable emergency stop button, whereby the plunger upper parts are individually designed for the respective functions, if the emergency stop button system from a first plunger top with a first closed bottom with a substantially flat surface, if the emergency stop button system has a second plunger top with a second base a light passage opening, and if the emergency stop button system from one third ram upper part with a third base with receiving means for a lock having.

The type of locking can also without additional parts for the invention Emergency stop button with lighting can be set when the plunger latches has, both for a train release, as well as for a rotary release can be used.

The emergency stop button can be combined as required when switching, lighting and / or further functional elements can be snapped into the base in a modular manner.

Fig. 1 shows a lockable emergency stop button 1 with an actuating head 2 and a connecting part 3 with a threaded portion for panel mounting and the like. As FIG. 2 shows, the emergency stop button 1 from a key guide 4, a plunger 5, a mushroom bottom 6, a plunger sleeve 7, a spring 8, a compression spring 9, a torsion spring 10, a plunger top 11 shown in Fig. 1 , a lock 12 and a mushroom top 13 .

The plunger 5 is moved by the actuating head 2 with the intermediate compression spring 9 .

The key guide 4 has a tubular housing part 14 which is provided with a shoulder 15 , as can be seen in FIG. 3.

As FIG. 25 shows, the key guide 4 is provided with a first guideway 21 and a second guideway 26 . The first guideway 21 and the second guideway 26 are arranged next to one another parallel to the axial actuation direction (arrow direction Y in FIG. 24) (see also FIG. 28).

The first guideway 21 has a depth which is somewhat greater than the ball radius of the locking ball 20 , so that the locking balls 20 are practically enclosed and only movement of the locking balls 20 along the first guideway 21 is possible. A rotational movement or a relative rotational movement between the plunger 5 and the key guide is not possible because the locking balls 20 are pressed against the almost straight inner walls and are held in the first guideway 21 under the action of the spring 8 . As a result, only an axial movement of the plunger or the actuating head is possible. The first guideway 21 is provided for a train release.

In the tubular housing part 14 ( FIG. 3), the tappet upper part 11 can be inserted axially from above and is embedded and rotatably arranged there, wherein rotation by a limited angle is only possible if locking balls 20 are mounted in the second guideway 26 . If the locking ball 20 is arranged in the first guideway 21 , no rotation of the actuating head 2 or of the key guide 4 is possible.

The key guide 4 has, as can be seen in FIG. 28, a first guide track 21 that runs straight with respect to the longitudinal axis, each with a locking ball 20 that can be immersed in this guide track 21 and is under spring action, as also shown in FIG. 24.

In the first guide track 21, the first projection 37 (Fig. 24), wherein the first guide path 21 and the first protrusion 37 are formed according to the invention such that only a pull release is possible. The locking ball 20 is caught, but can be pressed by vigorously hitting the actuating head 2 over the first projection 37 due to the bevel or wall 35 .

The key guide 4 has, as shown in Fig. 25 and 28 shows a plane parallel to the first guide rail 21 second guide rail 26, in each case the locking ball 20 according to the invention can be used either. That is, Depending on the type of locking, that is to say whether pull release or rotary release is desired, the locking ball 20 or the two opposite locking balls 20 can be inserted into the first or second guideway 21 , 26 .

The locking balls 20 (in principle also the spring 8 ) can be inserted through the mounting holes 27 arranged on the key guide 4 ( FIG. 2). By subsequently turning left or right, the locking balls enter the corresponding guideway.

A second projection is in the second guideway 26, as shown in FIG. 3, arranged 22, wherein the second guide track 26 and the second protrusion 22 are formed in such a way that only a rotary release is possible.

The locking balls 20 are arranged at the ends of a spring 8 , wherein the locking balls 20 can be completely immersed in a tunnel 33 . As is also shown in FIG. 6, the tunnel 33 is arranged transversely to the direction of actuation. The spring 8 is embedded in the tunnel 33 , the spring 8 being a compression spring. The tunnel 33 is arranged on the tappet 5 .

The second guide track 26 has a side wall below the second projection 22 in a second tripped area 70 , which is provided with such a curve shape with respect to a cross section that the locking ball 20 immerses as far as the actuating head 2 rotates in the direction of the curve 30 can that the locking ball 20 can bypass the second projection 22 when the actuating head 2 is moved by a rotary and spring action automatic stroke movement from a released position to the off position. The second guideway 26 has, below the second projection 22 in the second triggered area 70, an asymmetrically deep depression with a curve shape with a flat inclination 30 on one side and a steep wall 73 on the opposite side, as shown in FIG. 25.

In this embodiment, the actuating head 2 is rotatable in none of the embodiments, but only the lock 12 , which is firmly connected to the ram upper part 11 c. However, the actuating head 2 can be rotated without a lock just as well as in known rotary unlockings.

A second upper projection surface 23 ( FIG. 3) of the second projection 22 , in which the locking balls 20 meet them from the off position into the released position, is shaped and designed in this way, that is to say, for. B. shaped obliquely that pushing away or immersing the locking ball 20 can take place.

The second lower projection surface 25 ( FIG. 3) of the second projection 22 , in which the locking ball 20 meet in the direction from the released position to the off position, is shaped and designed (rectangular) so that pushing away or immersing the Bolt ball 20 is not possible without turning the lock (the actuating head as an alternative).

On the one hand, the first guideway 21 , as shown in FIG. 25, has a depth which is greater than the radius of the ball of a locking ball 20 , and the first guideway has a side wall shaped in such a way that the locking ball 20 is enclosed in the first guideway 21 and cannot get out of the first guideway 21 , whereby only a movement of the locking balls 20 along the first guideway 21 is possible. On the other hand, the first guideway 21 has a depth in which the locking ball 20 can only immerse into the first guideway 21 to such an extent that there is no substantial play when trying to turn the lock (the actuating head 2 ) (the depth corresponds approximately the sphere radius).

A first upper projection surface 35 ( FIG. 24) of the first projection 37 , in which the locking balls 20 meet from the off position into the released position, as shown in FIG. 26, is shaped and designed such that it is pushed away or immersed the locking ball 20 can be done.

The first lower projection surface 38 ( FIG. 24) of the first projection 37 , in which the locking ball 20 meets them in the direction from the released position to the off position, is shaped and designed such that pushing or immersing the locking ball 20 also occurs is possible.

The tappet upper part 11 can be rotated completely in the housing part 14 if no locking balls 20 are installed. The tappet upper part 11 has a second shoulder 16 , as shown in FIG. 3. The torsion spring 10 is arranged between the first shoulder 15 of the housing part 14 and the second shoulder 16 .

The compression spring 9 is arranged between the tappet upper part 11 and the tappet 5 , which is supported on a surface 17 of the tappet upper part 11 and a third shoulder 18 of the tappet, as shown in FIG. 3.

The plunger 5 has essentially a tubular or hollow shape.

At two opposite openings 19 of the plunger 5 , a locking ball 20 partially protrudes ( FIG. 2). The locking balls 20 are under the pressure of the intermediate compression spring 8 .

As already explained, the locking balls 20 are held either in a first guideway 21 or in a second guideway 26 . The first guideway 21 and the second guideway are arranged on the key guide 4 .

The first guideway 21 is provided for a train release. A train release is advantageous if no key lock 29 is used, as is provided in the embodiments shown in FIGS. 20 and 24.

The second guideway 26 is provided for rotational unlocking. Rotary unlocking is advantageous if a key lock 29 is used, as is provided in the embodiment shown in FIG. 3.

When the rotary unlocking (as already explained) in the unactuated state, the locking balls 20 rest against a second projection 22 , the second projection having an oblique edge or second upper projection surface 23 , as shown in FIG. 3.

The plunger 5 presses the locking balls 20 against the bevels or the second upper projection surface 23 under the force of the compression spring 9 without the locking balls being pressed inwards. That is, the spring forces of the springs 8 and 9 are dimensioned accordingly.

When the actuating head 2 is pressed or struck, the locking balls dip into the openings 19 until they have been moved over the second projection 22 and, after reaching an edge 24 or second lower projection surface 25 , protrude again from the openings 19 .

Behind the edge 24 there is a second lower projection surface 25 arranged at right angles, which holds the emergency stop button 1 in the pressed position. In the non-rotated position, the second lower projection surface 25 has a depth which prevents the locking ball 20 from reaching the off position. The surface 25 has no angle of inclination.

In order to unlock the emergency stop button and bring it into the unlocked position, the lock (the actuating head 2 ) is rotated until the locking ball 20 is immersed in the opening 19 until the locking ball 20 is no longer supported on the surface 25 can. This required rotation identifies the emergency stop button as a button with a rotary release.

The housing part 14 has a second guideway 26 which is provided for the rotational unlocking. As shown in FIG. 25, the second guide track 26 below an second projection 22 has an asymmetrical shape or a relatively flat wall profile or flat inclination 30 or curve. When the lock (actuating button 2 ) is turned in the direction of the inclination 30 , the locking ball 20 can be immersed.

FIGS. 6, 8, 16 show the locking balls 20 as they are mounted in the first guide track 21.

The locking balls are mounted in the first guideway 21 in such a way that the plunger 5 is guided in the housing part 14 such that it cannot be rotated, so that a train release is then possible. So that the actuating head 2 can be pulled into the original position without a rotary movement but only by pulling, a projection 37 is arranged in the first guideway, as shown in FIG. 24, which has a surface 38 which is shaped obliquely at the bottom.

The sloping surface can be overcome by pulling with a certain force.

As shown in FIG. 4, the emergency stop button 1 is provided with a thread 31 for the usual fastening. The emergency stop button 1 is provided with snap-in switch elements 32 which can be actuated by the plunger 5 and the plunger sleeve. This shown emergency stop button 1 can be unlocked with a lock 12 or only unlocked with a key, which is shown in FIG. 5 from above.

In FIG. 6 is a sectional view of the emergency stop button 1 is shown in non-actuated position, wherein the locking balls 20 are arranged above the projections 22 and 37. The first and second guide tracks 21 , 26 are shaped above the projections 22 and 37 such that the locking balls 20 prevent the actuating head 2 or plunger 5 from rotating relative to the key guide 4 .

In principle, a rotary movement of the actuating head 2 is prevented by the second guide ribs and guide grooves 43 , 44 in all the embodiments shown here.

Fig. 7 shows in a sectional view along the section line AA in Fig. 4, the unlockable emergency stop button 1 , in which the lock 12 (lock cylinder) is shown in a sectional view.

The lock 12 prevents unlocking of unauthorized persons. To unlock, however, turning with a key is required so that only authorized persons who have a key can move the emergency stop button 1 back into the off position.

The switch elements 32 are shown in section in FIG. 7.

To cooperate with the lock 12 , the ram upper part 11 is provided with molded ribs 36 , which are shown in Fig. 10.

The sectional illustration shown in FIG. 8, for example, according to the section line EE in FIG. 4, shows a tunnel 33 , which is arranged symmetrically like a bridge between the wall 35 of the tappet upper part 11 . The tunnel 33 is open at both ends, so that the locking balls 20 can be fully inserted. The spring 8 is embedded essentially flush in the tunnel 33 , as can be seen in particular in FIG. 7. In the middle of the tunnel 33 , rectangular openings 34 are arranged at the top and bottom, which will be explained in more detail later.

The plunger 5 is essentially hollow. The mechanical connection to the tappet upper part 11 takes place by means which are arranged on the outside of the tappet.

So that the plunger 5 in the plunger upper part 11 is on the one hand longitudinally displaceable by a limited path and on the other hand non-rotatably connected to the plunger upper part 11 , the plunger 5 is provided with first latching lugs 40 which engage in corresponding window-like openings 39 , as in FIG. 2 or FIG. 9, which shows a sectional illustration along the section line FF in FIG. 5, is shown. The width of the locking lug 40 is slightly less than the width of the opening 39 . The locking lug 40 is displaceable in the actuation direction Y within the opening 39 .

The non-rotatability is realized by first guide ribs 41 ( FIG. 7) formed on the plunger 5 in the actuating direction and which can be displaced into corresponding first guide grooves 42 of the upper part 11 of the plunger, as can be seen in particular in FIGS . 7 and 9.

The key guide 4 has second guide ribs 43 which engage in second guide grooves 44 , the second guide grooves 44 being arranged on the mushroom lower part 6 belonging to the actuating head 2 , as shown in FIGS. 2 and 9. Mushroom lower part 6 and mushroom upper part 13 form the actuating head 2 , these being connected by latching means 45 , 46, which are identified in FIG. 2.

Fig. 11, which shows a sectional view along the section line CC (angularly offset section) in Fig. 5, shows the switch element 32 , which is provided with a switch cam 47 and can be actuated by the plunger sleeve 7 , the plunger sleeve 7 with the plunger 5 is rotatably connected.

For this purpose, second locking lugs 48 are arranged on the tappet sleeve 7 , which engage in guide slots 49 ( FIGS. 2 and 12).

Characterized in that the ram sleeve 7 with laterally arranged pegs 50 (Fig. 2) is provided and the pins are set 50 in non-rotatable manner in recesses 51 of the tappet guide 51, the plunger 5 can be turned only within the slot length 49 of the guide slot 49. Allowing this rotation is important for unlocking the actuating head 2 during the rotational unlocking. In this type of unlocking, the locking balls 20 are immersed in the tunnel 33 during the rotational movement, with which the actuating head 2 and its parts connected to it can be pulled up because the first projection 22 shown in FIG. 3 acting as a lock is bypassed.

After striking the actuating head 2 , the locking balls 20 move behind the projection 22 , analogously to the position shown in FIG. 24. Wherein Fig. 24 shows a sectional view of the emergency stop button, in the actuated state.

Fig. 28 shows the first guide path 21 for the lock-out part comprising a first training portion 71, a first projection 37 and a first portion 72 tripped.

28 further shows the Fig., The second guide path 26 for the pull and twist to having a second off portion 69, a second projection 22 and a second tripped area 70 with the slope 30 and the steep wall 73.

Furthermore, the projections 22 , 37 on the side of the off area 69 , 71 are provided with troughs 74 , in which the locking balls 20 are held in the off position and enable a defined position.

As shown in FIG. 30, a total of four guideways 21 , 22 are provided, two of which are arranged opposite each other.

A displacement of the pin 50 in the actuating direction is possible within the recesses 51 .

To seal the rotatably movable plunger upper part 11 or actuating head 2 to the key guide 4 or the other fixed parts, the key guide 4 is provided with two sealing lips 52 , 53 , which are made of soft material and can be injection molded, as in FIG. 3 is shown.

The two sealing lips 52 , 53 offset in height are arranged at an oblique angle in the head direction.

As shown in FIG. 15, the emergency stop button can be practiced without sealing lips.

Instead of a lock 12 , as shown in FIGS . 18 to 22 and 26, the emergency stop button can be provided with a translucent window or button head opening 54 bc and a light element in the form of a functional element 53 with a light emitting diode 55 , the functional element 53 only is shown in Fig. 26. As FIG. 24 shows, an actuating head without window or key opening bc and without lock 12 can also be used.

At the location of the translucent window 54 , a lens 56 is arranged, which consists of a disk-like lens region 57 and a sleeve-like body 58 which is adapted to the dimensions of the lock 12 .

The lens area 57 is recessed on the inside like a dome. The lens 56 is colored red. The shape and the dimensions of the lens 56 correspond to those of the lock in the head-side region, as a result of which the same mushroom upper part 13 bc as shown in FIG. 31 can be used.

So that the light emitted by the light-emitting diode 55 ( FIG. 26) reaches the lens region 57 , the tappet sleeve 7 , the tappet 5 , and the tappet upper part 11 c are designed to be hollow or with a cavity. The openings 34 provide an improvement in light transmission.

As FIG. 31 shows, the emergency stop button has a modular or modular design.

For better differentiation, the reference numerals of the corresponding parts are marked with a provided that the emergency stop button is a simple emergency stop button without lighting, without lockability and train release.

With an emergency stop button with lighting and pull release, the parts are with the Reference number b provided.

The parts come with a lockable emergency stop button and a rotary release provided with the reference symbol c.

The kit consists of a first mushroom head 13 a without a window 54 with a closed surface 55 'for use in a simple emergency stop button and a second mushroom head 13 bc for use both for an emergency stop button with lighting and pull release and for a lockable emergency stop Button with rotary pull release.

Furthermore, the kit consists of three different plunger upper parts 11 a, 11 b, 11 c for the three different emergency stop buttons, a torsion spring 10 c for an unlockable emergency stop button with rotary unlocking, a common compression spring 9 , a common plunger 5 , a common key guide 4 , and a common mushroom base 6 for the three different types of emergency stop. The modular system has a tappet sleeve 7 ac for common use in a simple emergency stop button and a lockable emergency stop button. Another tappet sleeve 7 b is provided for an emergency stop button with lighting and release.

A simple emergency stop button is neither unlockable nor has none Lighting on. It can be unlocked in any way.

Emergency stop buttons, which can be assembled in a modular manner according to FIG. 31, contain different functions, such as unlockability and illuminability. The emergency stop buttons consist of a mushroom-shaped actuating head 2 and a base body composed of various parts with movable and fixed parts.
