Definitions

  • the invention relates to a key switch with a guided in a frame, biased against its axial actuation direction in the rest position and in its working position actuating at least one contact spring set, and with a locking the key shaft in the working position and releasing when pressed again, the switching gate with a heart curve and includes a cam follower guided therein, the switching link and the cam follower being able to be moved in an approximately perpendicular triggering direction to the actuating direction of the push button shaft and the plane of the heart curve, relative to each other, for external control of the locking position of the switching lock independently of the key actuation.
  • Such pushbuttons are preferably used in telecommunications systems, for example in telephone sets, to control the operating state, for example from the dialing state to the receiving state and vice versa, and on the other hand to control an additional function such as listening.
  • a push button switch is already known, which is designed for double-pressure actuation.
  • a push-button shaft actuating the contact spring sets is locked by means of a key switch when depressed for the first time and released from the locked working position when depressed again.
  • the key switch used has a backdrop with a heart curve, in which a guide pin fastened to the push button shaft and movable with it slides and automatically ensures the locking or releasing of the push button shaft when passing through the heart curve.
  • a push-button switch according to the preamble of claim 1 is described in DE-B-1 415 591.
  • a locking lever with a heart curve is attached to the pushbutton shaft that is moved in the longitudinal direction when the switch is actuated, and a locking pin engages in this when the pushbutton is actuated.
  • This locking pin is in turn attached to the armature of an electromagnet mounted in the frame.
  • the electromagnet is excited so that the locking pin is pulled out of the heart curve and the key shaft together with the locking lever is released for return movement to the rest position.
  • DE-A-2 846 198 describes an electrical switch which can be locked in its working position by means of a catch.
  • This catch is fixed in a holding body made of fusible material, which can be melted by electrical heating, so that the catch is released and thus the locking position of the push button switch is released.
  • the external triggering is also based on an electrical power supply in this switch.
  • a key switch system for electromagnetic and mechanical interlocks in which the key shaft is locked by means of a locking mechanism after being depressed.
  • This locking mechanism can be controlled by a magnetic coil by electrical excitation such that the locking position is released.
  • DE-A-1 064 562 also describes a light button for telecommunications systems, the switch lock of which corresponds to that of DE-G-1 179 259 mentioned above, that is to say no external triggering is permitted.
  • the object underlying the invention is to develop a push button switch of the type mentioned in the preamble of claim 1 in such a way that the external triggering is possible without the use of electrical energy.
  • the push button switch consists of a frame 10 with a base 11, on which, on the one hand, a bearing block 13 for a release lever 15 and, on the other hand, an upwardly projecting holder 12 for the actual switch unit 30 are molded or attached are.
  • the bracket 12 and the bracket 13 are aligned with each other such that one end of the trigger lever 15 pivotally mounted on the journal 14 of the bracket 13 can engage with an actuating element 72 of the switch 60 of the switch unit 30.
  • the arm 82 of the release lever 15 projecting from the switch unit 30 can be actuated by a fork plunger 16 which moves together with the fork 18 of a telephone set when a handset 17 is placed or removed.
  • the switch unit 30 has a frame 31 which is attached to the holder 12 of the frame 10 in a suitable manner, for. B. is fastened by screwing.
  • a push button shaft 32 is slidably guided in the longitudinal direction.
  • the push-button shaft 32 consists of a tubular sleeve 34 and a switching cam 33 attached or molded to the lower end thereof, which is provided on its lower outer peripheral edge with bevels (3) for actuating the contact spring sets 39 which are insulated in a contact base 40.
  • a button head 36 is attached to the upper end of the button shaft 32, outside the frame 31 and the frame 10.
  • This key head 36 serves on the one hand for manual actuation of the key switch and on the other hand as a protective cap for the indicator 50 accommodated in its interior cavity.
  • the key head consists of a material which is transparent at least on the upper end face, e.g. B. made of plastic.
  • the display part of the indicator 50 which is visible through the transparent button head 36, is designed like a conventional star indicator and therefore does not require any detailed explanation. It consists of a cap-shaped diaphragm 52, divided into sectors of 60 ° in each case, and a star bell 51 which can be rotated back and forth within this diaphragm 52 by approximately 60 ° and is provided with sector-shaped color markings, which is particularly clear in FIGS is recognizable.
  • a spindle 53 Projecting axially downward on this star bell 51 is a spindle 53, which is received in an axial bore 41 in the tubular sleeve 34 of the push-button shaft 32 and is rotatably guided therein in the radial direction.
  • the spindle 53 is generally cylindrical in shape, but extending over part of its length is a spiral helical surface 54 which is axially closed on both sides by radial shoulders 57 at a distance from the respectively adjacent ends of the spindle, so that at both ends of the spindle in each case a cylindrical spindle collar 58 remains, which is the radial one Guidance of the spindle 53 within the axial bore 41 ensures rotation.
  • the axial fixation of the spindle 53 is ensured by a spindle counter bearing 56 formed centrally in the diaphragm 52, on which the uppermost point of the star bell 51 is rotatably supported.
  • a switching pin 55 is provided transversely to the direction of actuation of the push-button shaft 32 and runs diametrically through its longitudinal center axis, the two ends of which are anchored in diametrically opposite bores of the frame 31 of the switch unit 30.
  • This switching pin on the one hand passes through two diametrically opposed, longitudinal slots 35 in the tubular sleeve 34 of the push-button shaft 32 and, on the other hand, slidably abuts the helical surface 54 of the spindle 53 of the indicator 50.
  • This arrangement ensures that the helical surface 54 of the spindle 53 slides on the switching pin 55 fixed in the frame 31 and forcibly executes a rotational movement when the push-button shaft 32 is depressed or when it returns from the locking position. In this way it is achieved without the use of external energy that when the push-button shaft is depressed and also when it returns in the opposite direction, the star bell 51 fixedly connected to the spindle 53 is rotated by a predetermined angle, so that the color markings of the star bell 51 either from the fixed aperture 52 are covered or released and made visible.
  • the switch positions of the pushbutton switch are thus forcibly mechanically coupled directly to the two display positions of the indicator 50.
  • the switch lock 60 of the embodiment of the push-button switch shown in FIGS. 1 and 2 has a rocker 70 which can be pivoted in bearings 71 attached to the frame 31 of the switch unit 30 about a rocker axis aligned transversely to the actuating direction of the push-button shaft 32.
  • the part of the rocker 70 projecting downward from the rocker axis 64 is equipped with an actuating element 72 in the form of a freely rotatable roller and to the left in FIG. 1 by means of a return spring 73 which is supported on the frame 31 biased.
  • a shifting link 65 designed in the form of an arm movable on one side about a pivot bearing 63 is attached.
  • a heart curve 66 of known shape, which is open toward the frame 31 of the switch unit 30, is formed in this switching link 65.
  • a transversely extending recess 69 is formed in the switching link 65, which is interspersed with play by a spring pin 67 anchored to the rocker 70.
  • the spring pin 67 carries springs 68 on both sides of the shift gate, which are supported on the one hand on the rocker 70 and on the other hand on the associated side of the shift gate 65, so that the heart curve 66 of the shift gate is biased into a predetermined rest position and can be deflected from this rest position to both sides .
  • the second element of the switch lock 60 which interacts with the heart curve 66 of the switching link 65 is designed in the form of a guide pin 61 anchored in the push-button shaft 32 and projecting laterally transversely to its longitudinal axis.
  • This guide pin protrudes through an elongated recess 62 formed in the frame 31 parallel to the direction of movement of the push-button shaft and beyond the outer surface of the frame 31 so that its free end can engage the switching link 65.
  • the pushbutton shaft 32 is pressed downward again in the actuating direction, as a result of which the guide pin 61 emerges from the catch groove 66b along the heart curve 66 to the bottom right. If the push-button shaft is released in this fully pressed position, it moves together with the guide pin 61 under the action of the springs 37 upward against the actuation direction and the guide pin 61 slides upward on the right edge of the switching link 65 (FIG. 6), until it returns to its released rest position above the shift gate 65. During this upward movement of the guide pin 61, the switching link 65 is pivoted counter to its spring preload to the left in FIG.
  • the locking position of the push shaft 32 and thus the working position of the contact spring sets 39 can be released without manual intervention in that the rocker 70 of the switch lock 60 from the position shown in FIG. 1 into the position shown in FIG. 2 shown position is pivoted against the biasing force of the return spring 73.
  • the shifting gate 65 together with the rocker 70 is moved away from the frame 31 in such a way that the guide pin 61 slides out of the catch groove 66b of the heart curve 66 and, together with the push-button shaft 32, freely moves upward against the actuating direction under the action of the springs 37 can move so that the key shaft 32 comes to its rest position in which the contact spring sets 39 are not actuated.
  • a one-time pivoting of the rocker 75 carrying the rocker switch 65 of the key switch 60 thus ensures that the push button switch returns to its rest position if it was in the locked position before actuation of the rocker 70 or remains in its rest position if it had previously been used .
  • the two-armed trigger lever 15 is pivotally mounted on the frame 10 of the pushbutton switch, the lever arm facing the switching lock at the free end of which carries two mutually angled sliding surfaces 80 and 81, each of which can slide along the actuating element 72 when the trigger lever 15 is pivoted and this presses against the return spring 73 towards the frame 31, that is, the rocker 70 is pivoted in the desired sense to release the switch lock.
  • Fig. 1 it can be seen that this function is possible starting from two pivot positions of the trigger lever 15. Starting from the position of the trigger lever 15 shown in solid lines, the sliding surface 81 causes the rocker 70 to pivot, while in the reverse movement, starting from the position of the trigger lever 15 shown in broken lines, the sliding surface 80 engages with the actuating element 72.
  • the other lever arm of the trigger lever 15 is designed as a fork-like slotted arm 82, the fork prongs of which engage around the fork plunger 16 of the fork 18 of a telephone set (not shown).
  • the fork plunger 16 is moved downward in FIG. 1, whereby the release lever 15 is pivoted upward from the position shown in solid lines in FIG. 1.
  • the release lever 15 is automatically pivoted out of the position shown in dash-dotted lines in FIG. 1, the switch lock 60 again being unlocked in the manner described above.
  • the fork opening of the slotted arm 82 can be adjusted by means of a screw 83.
  • This exemplary embodiment of unlocking the switch lock 60 is particularly advantageous in practice in the case of a telephone apparatus if, for example, a listening device or a loudspeaker device is switched on by the push-button switch. Whenever the handset is removed from the fork or put back on it, it is ensured at the same time that the key switch is returned to its unlocked rest position, in which, for example, the monitoring device is switched off. This can ensure that the monitoring device does not remain switched on inadvertently.
  • FIGS. 1 to 6 A further embodiment of the push-button switch according to the invention is shown in FIGS.
  • the parts corresponding to the embodiment of FIGS. 1 to 6 are provided with the same reference numerals.
  • this exemplary embodiment differs from the one explained above, in particular in the design of the switch lock 100.
  • the switch gate of the switch lock 100 is formed in the side face of the push-button shaft 85, that is to say with the push-button shaft when actuated Heart curve 84, which can be moved up and down, is also of conventional construction.
  • the second element of the switch lock 100 which interacts with the heart curve 84 for locking purposes is shown as a guide pin 74 which is connected to a rocker 75 which is pivotably mounted on the outer surface of the frame 31 of the pushbutton switch. As shown in FIG. 8, this rocker 75 can be pivoted by means of a rocker shaft 96 in bearing blocks 97 attached to the frame 31.
  • a spirally wound spring 78 is attached to the rocker shaft 96 and has two free straight legs 78a and 78b.
  • the lower leg 78a of the spring 78 is supported on the frame 31, while the upwardly projecting leg 78b is fastened to the outside of the rocker 75 by means of a spring fixation 95.
  • This arrangement of the spring biases the rocker 75 against the frame 31 in the rest position.
  • the preferred below the cradle shaft 96 part of the rocker 75 has designed as a freely rotatable roller actuator 72, as shown in FIG.,
  • the "sliding surfaces 80 and 81 of a trigger lever 90 can engage to pivot the rocker 75.
  • a recess 77 is formed, in which a slide 76 is received so as to be displaceable transversely to the actuating direction of the push-button shaft 85.
  • Attached to the carriage 76 is the guide pin 74 which, when the rocker 75 is in the rest position, projects through a slot 98 in the frame 31 and can engage with the heart curve 84 of the push-button shaft 85.
  • the laterally displaceable in the rocker 75 together with the guide pin 74 slide 76 is biased by the upper leg 78b of the spring 78 into a rest position from which it can be deflected on both sides when the guide pin 74 engages with the heart curve 84.
  • To guide the leg 78b two guide brackets 79 are attached to the outside of the rocker 75.
  • the guide pin 74 and the slide 76 of the rocker 75 can also be replaced by a ball which can move freely in a groove in the rocker 75 if the heart curve 84 is suitably known.
  • the trigger lever 90 shown in the exemplary embodiment in FIG. 7, the function and mode of actuation of which completely correspond to the trigger lever 15 of the exemplary embodiment in FIG. 1, is designed in a special way.
  • Its lever arm facing away from the switching lock 100 is designed as a fork-shaped slotted arm 91 which is pivotally and fixably attached to the main body of the release lever 90 by means of a bearing pin 94.
  • an arc slot 92 is formed in the slotted arm 91, through which, as can be seen in particular from FIG. 9, a clamping screw 93, which can be screwed into the main body of the release lever 90, projects.
  • the resulting angular adjustment of the slotted arm 91 allows the interaction of the trigger lever 90 with, for example, the fork plunger 16 of a telephone set to be precisely adjusted in a particularly advantageous and simple manner, as already explained with reference to FIG. 1.
