Definitions

  • the present invention relates to an impulse push button of the type comprising a tubular plunger housed coaxially in a cylindrical body to act on electrical contacts, guided in translation in the body and biased by a return spring.
  • Such impulse push buttons also called single push buttons, are well known.
  • snap-on push buttons also called push-push buttons or double thrust
  • a cam with an attachment zone, for example in the shape of a heart
  • a pin spring for obtain, at the end of the downward movement of the pusher, the retention of the pin in the cam attachment area prevents the ascent of the pusher; during the next actuation of the pusher, the pin is released from the attachment zone during the downward movement of the pusher and the latter can go up freely.
  • a mechanism is dedicated to hanging specific to the type of button considered.
  • the object of the invention is to provide sound and tactile feedback to the user of a single push button with dependent action, i.e. without sudden break, this return being significant of the good functioning of the push button and being obtained by simple means.
  • the pusher has a wall provided with a cooperating cam with an active part, for example a terminal part, of a shaped spring pin, this pin being also embedded in the body and storing energy as a function of its stress on the cam; else hand, the cam has a profile provided with at least one cusp, this profile being traversed, entirely and without holding hook, by the part active pin, following an actuation cycle of the pusher, that is to say a movement of descent and ascent of the pusher; finally, the wall of the pusher has a projection associated with the cusp point for allow a jump of the active part of the pin.
  • an active part for example a terminal part
  • the cam has a profile provided with at least one cusp, this profile being traversed, entirely and without holding hook, by the part active pin, following an actuation cycle of the pusher, that is to say a movement of descent and ascent of the pusher; finally, the wall of the pusher has a projection associated with the cusp point for allow a jump of
  • the terminal part of the pin is an elbow whose end radial is able to strike the bottom of the projection when crossing it by the elbow.
  • Figure 1 shows in axial section a push button according to the invention.
  • FIG. 2 is an enlarged view of detail A of FIG. 1.
  • FIG. 3 is the view along B of the detail in FIG. 2.
  • Figure 4 shows in perspective the cam of the push button.
  • FIGS. 5A to 5E show the phases of the relative movement of the cam and of the needle during a push button actuation cycle.
  • Figure 6 shows an alternative embodiment of the cam.
  • the impulse push button shown in Figure 1 includes a tubular body 10 of generally cylindrical shape with axis X, provided with a head 11 opened out with respect to a barrel 12.
  • a generally cylindrical pusher 20 composed of an upper part 20a open to be housed in the head 11 and a bottom part 20b secured of the part 20a and movable in the barrel 12; the pusher is movable in the body 10 so as to move in translation along X in response to a pressure exerted on its upper part 20a, against the effort of a coaxial helical return spring 21, while being immobilized in rotation around X.
  • the pusher is stopped in the high position in the body by stop means not shown.
  • the term cylindrical must be understood in broad sense and also designates prismatic or similar forms.
  • the pusher is guided and kept in rotation by means of suitable shapes, for example as indicated in 13 and 22.
  • the pusher 20 is tightly attached to the body by a seal 14 and forms inside a room 23 which can accommodate a sight glass.
  • the pusher 20 has on its cylindrical periphery a wall 24 and, on the outer face 25 of this wall, a cam 30 which cooperates with a part active 16, preferably a terminal portion bent radially towards the axis X, of a pin-shaped spring or the like; the end 16a located towards the X axis of the terminal part 16 is applied against the face 25.
  • the other end part 17 of the pin 15 is embedded in a housing 18 of the lower end of the body 10.
  • the pin 15 extends in a direction X1 parallel at X, along the cylindrical wall of the barrel 12 and preferably in a groove or slot 19 thereof. As we will see later, the pin 15 is secured to the cam so as to accumulate by bending a energy to obtain the desired tactile and sound effect, in combination with a percussion effect due to the escape of its end on adapted shapes of the face 25.
  • the cam 30 has substantially the shape of a parallelogram having two sides 32,34 essentially parallel to the X axis of the body and two other sides obliques 31,33.
  • the oblique side 33 located towards the head 11 of the push button has a flat or convex shape without discontinuity and the oblique side 31 of the cam located opposite the head can also have a continuous shape (see Figures 5A-5E) or may offer a discontinuity providing resistance touch (see Figure 6).
  • Cam offers a cusp 35 (acute angle of the parallelogram) at the transition between the sides 32.33 and a another cusp 36 at the transition between sides 34 and 31.
  • the outer face 25 of the wall 24 comprises a ramp slightly rising 26a to guide the end 16a of the elbow 16 of the pin 15 along side 31 and a bowl or similar recess 26b adjacent to the ramp 26a to provide a projection 27 in the vicinity of the cusp 35; likewise; a slightly rising ramp 28a is provided for guide the end 16a of the elbow 16 along the side 34 and an adjacent recess 28b to the ramp 28a to provide a projection 29 close to the cusp 36.
  • the push button described operates as follows.
  • the initial position is illustrated in Figures 1 and 5A; in this position, the pusher 20 is applied in abutment against an element of the body, while the upper face of the elbow 16 is located in the immediate vicinity of the side lower 31 of cam 30, or is applied on this side, the pin being at rest.
  • the pushbutton causes the rightward sagging of the pin (see Figure 5D) due to the sliding of the side 33 of the cam against the elbow 16.
  • the end 16a of the elbow 16 rises on the ramp 28a and, when the elbow crosses the cusp 36 and the jump 29 associated ( Figure 5E), it strikes the face 25 in the recess 28b, so that the user perceives a sound and a tactile reaction as before.
  • cusps, ramps and jumps can be sized to favor for example the first indication (jump 27).
  • a single projection can be provided.
  • FIG. 6 shows a variant in which a discontinuity 37 is provided in the side 31 of the cam 30 to mark a resistance touch at the start of actuation.
  • Cams shown as an example can of course take other equivalent forms.
