Definitions

  • the invention relates to an indicating push button mechanism, more particularly for push button switches, comprising two viewing plates which can be seen through a front window and reflect light from the surroundings.
  • the surface serving for providing an indication is too small in relation to the size of the front surface of the button, something which is more particularly curved by the complicated mechanical switching or operating mechanism.
  • the indicating means is too far removed from the viewing window of the push button head so that in particular in the case of viewing the push button and the sign obliquely no clear information as to the setting is received.
  • the indicating surfaces are curved, something which makes labelling them difficult.
  • One aim of the present invention is to avoid these disadvantages and to provide an indicating push button head with means for indicating positions and which can readily be inspected even when not looked at directly, that is to say when it is looked at obliquely.
  • a further aim of the invention is to provide such a mechanism which operates reliably over long periods of time.
  • the present in vention provides that the viewing plates are arranged so as to be individually rotatable in the housing of the push button adjacent to the window and at least one of them is pivotally mounted on a pivoting lever. This lever is acted upon by the movement of a sliding switch, and it assumes two distinct angular positions and swings one of the two viewing plates into the field of view of the window.
  • two comparatively large viewing plates can be swung alternately into the field of view of the window of the button. Since they swing or fold inwards during the time of changing over by a swinging movement, the pivotal changing over occurs with the minimum space requirement and the radius of the swinging lever can nevertheless be made comparatively large.
  • the button would haveto be made many times larger, if approximately the same radius as with the invention were to be provided on the head. In the case of a smaller radius the distance from theviewing window would be greater.
  • FIG. 1 is a perspective view of an indicating push button head' mechanism in accordance with the invention, partly broken away. I
  • FIG. 2 shows an axial section of a push button head in the non-depressed position.
  • FIG. 3 is a sectional view of a push button head-approximately in the half-depressed position.
  • FIG. 4 is a sectional view of the push button after being completely depressed.
  • FIG. 5 shows a section of another embodiment of the invention with the push button head not depressed.
  • FIG. 6 shows the embodiment of FIG. 5 with the push button head half depressed.
  • FIG. 7 shows a section corresponding to FIG. 5 with the push button head completely depressed.
  • FIG. 1 shows the spatial arrangement of the viewing plates 11 and 13, their bearing, the pivoting lever 8, its bearing or pivot 9, and the means for moving or controlling the viewing plates by means of driving grooves 15, 15. The manner of operation will be explained chiefly with reference to the diagrammatic representations of the other figures.
  • FIGS. 2 to 7 the following parts are well known in the art'and are of only subordinate importance for the invention:
  • the push button switch 1 with its push button plunger 2 and return spring 3, the switch frame or chassis 4, the push button housing 5 and the attachment means 6 forthe push button plunger on or in the push button housing.
  • the push button housing is'interrupted by a window 7 on the front part.
  • a window 7 on the front part.
  • the window 7 makes it possible to inspect the head looking at one of the two viewing plates A 11 and B 13, as shown in FIGS. 2 and 4 is well reflected, the viewing plates should be placed as close as possible to the window. This is facilitated by making the radius R large, which is defined by the pivoting lever 8 and the pivot point or bearing 9.
  • the viewing plates A and B have the common hearing means 10 which has means that is oriented generally parallel to window 7 and the pivoting lever and can therefore adapt themselves to the space available on turning of the pivoting lever 8 and the plates can assume an angle to each other (FIG. 3) which is less than
  • the angular driving means for the viewing plates A and B can be arranged in various different manners.
  • FIGS. 1 to 4 show two possibilities.
  • driving grooves 15 and 15 are arranged laterally in the interior of the push button housing 5 and they define a suitable curve or cam surface, which can cooperate with laterally extending pins 12, 14 on the sides, remote from the bearing 10, of the viewing plates or flaps.
  • the pins 12 or 14 lie against the front guiding surface or edge 18 and ensure that the viewing plate in question is parallel to the window 7.
  • the push button housing can be made in a simpler manner if the means for changing over the viewing plates is only along the outer guide curve 16, 16. In this case the pins 12, 14 are not necessary, if the guide curve 16, 16' extends over the whole breadth, or a reasonable part of it, of the interior space of the push button. In order to erect the viewing plates in front of the window 7 it is then, however, necessary to provide a spring 30 which on the one hand abuts against the push button housing, approximately at 32, and with the limb 31 presses the viewing plate towards the window 7.
  • FIG. 2 shows the indicating push button mechanism in the non-depressed position and the control slide 19 which is fixed in the switch frame 4 with the hook 20, has its nosepiece 21 at the same level with respect to window 7 as the bearing 9 on the edge 22 of the pivoting lever so as to be non-operative at this time.
  • the pivoting lever 8 is held by a compression spring 24 in a defined starting position.
  • the compression spring 24 has one end resting aginst the bottom of the housing and the other end engages the pin 23. In this position the viewing plate 11 appears inthe window 7.
  • the pivoting lever 8 turns into its defined terminal position.
  • the viewing plate 13 appears in the window 7 and the edge 22 of the pivoting lever comes into a position in which it is parallel to the direction of thrust; further depressing of the push button cannot lead to the nosepiece 21 changing the position of the pivoting lever 8 further so that the viewing plate 13 in the window 7 cannot react with-a change in position if the switch is pushed toofar.
  • -It may oftenbe the case that the small amount of space available inside a push button head does not allow the pivoting, of both viewing plates by the pivoting lever 8 and an arrangement of a viewing plate 13 on the pivot bearing 10, which bearing is oriented parallel to window 7, (FIGS. to 7) is sufficient, while the second viewing plate 25 is pivoted directly on the bottom of the housing, at bearing 26, which bearing is oriented parallel to window.
  • This viewing plate 25 is urged by a spring 28 towards the window 7, and the spring engages the pin 27 on the housing 5 of the push button.
  • the resiliently loaded viewing plate 25, which furthermore can be in the form of a strip spring, at the same time performs the task of the spring 30 of FIGS. 2 to 4, that is to say it springs in the off position of the push button (FIG. 5) automatically against the window 7 while in the depressed condition (FIG. 7) it is also pressed against the viewing plate 13.
  • FIGS. 5 to 7 show the manner of operation of the arrangement in three phases: off position FIG. 5, half depressed FIG. 6, depressed to the full FIG, 7.
  • the pivoting lever 8 can also make do without spring loading (spring 24 in FIGS. 2 to 4), if the edge 22 of the pivoting lever has a bay above the bearing 9 and the nosepiece 21 of the control slide 19 lying on the cranked part 22 defines the off position of the swinging lever.
  • FIG. 6 indicates how the viewing plate 25 moves inwards in order to allow a space saving swinging over of the viewing plate 13 so as to move towards the upper housing wall.
  • the viewing plates can have various contrasting colors and/or lettering.
  • a transparent insert in the window 7 it is also possible for a transparent insert in the window 7 to be let tered and in this case the contrasting colors seem to the rear indicate where the push button is switched on or switched off.
  • An indicating push button mechanism having two indicator plates for indicating two different button positions, comprising:
  • a hollow push button housing said housing having a viewing window thereinto through which the interior of said housing may be viewed;
  • lever in said housing; said lever being so supported in and being so movable in said housing that a portion of said lever is movable in said housing behind said viewing window and in a first direction across said window and also in a second direction opposite said first direction;
