Definitions

  • This invention relates to a push-button arrangement of the type used in radio apparatus.
  • a push button comprising one or more push buttons and a locking member preferably for each individual push button has been suggested, each push button being supported by a switching element comprising the locking member, which switching element is slidable in the pushing direction for controlling a switching mechanism and is tiltable about an axis, preferably imaginary, at right angles to the direction of sliding for locking or releasing the locking member.
  • each button it is possible by means of each button to choose between two positions of the switching mechanism.
  • the invention underlies the recognition that during the tilting movement at least part of the switching element may exhibit a component of movement oppositely directed to the corresponding direction of sliding, that is to say after a button has been pushed, an opposite movement of part of the switching element may follow during tilting, and when a button is released, a movement opposite to the subsequent sliding movement may occur during tilting. Consequently, during pushing and locking and also during the release and the subsequent sliding movement the movement of part of the switching element may each time be reversed.
  • At least part of the switching element during tilting exhibits a component of movement oppositely directed to the corresponding direction of sliding, said component of movement being used to control the switching mechanism, so that the change in position thereof is limited to part of the operating time of the device.
  • the device according to the invention permits not only of bringing about a permanent change in position of a switching mechanism but also of obtaining a change in position for a determined period.
  • the speed of the movement of the button only acts upon the duration of the change in position. Irrespective of this speed, however, it is always ensured that the change in position actually takes place and is obviated at the end of the operating period.
  • each part of the switching element on account of the particular shape of the locking surface of the locking member exhibits a component of movement oppositely directed to the corresponding direction of sliding, so that each arbitrary part of the switching element may be utilised to control the switching mechanism.
  • Figs. 1 and 2 show one embodiment comprising two buttons intended for recording and reproduction, respectively.
  • Fig. 1 is a sectional view taken along the line I'I of Fig. 2, but in which, contrary to Fig. 2, the two buttons are assumed to-occupy positions.
  • Fig. 3 shows the button of Fig. 1 at the moment of being locked and i Fig. 4 shows this button in the completely locked position.
  • a carrier plate 1 has secured to it a U-shaped clasp 23 by means of rivets 24 and 25.
  • the two tree limbs of the U are bent inwardly, thus forming extensions 26 and 27.
  • An aperture 28 of the carrier plate 1 is such that the switching elements 29 and 30 are not guided by it. This is effected in apertures 31, provided in the extensions 26 and 27, and in apertures 32 of the clasp 23.
  • Springs 33, 34 are secured, on the one hand, to extensions 35 and 36 of the switching elements 29 and 30 and, on the other, to extensions 37, 38 of the clasp 23.
  • a pin 39 it is possible to operate a lever 40 connected by way of a rod 41 to a switching mechanism for recording or reproduction.
  • the upward movement of the elements 29 and 30 is limited by the parts moved by them.
  • the downward movement of the elements 29 and 30, if the elements have not been locked beforehand, is at any rate limited due to the extensions 35, 36 abutting against the parts 26, 27.
  • the elements 29, 30 are operated by but tons 42, 43.
  • the upper surfaces 44 thereof are of a particular shape to facilitate the operation.
  • a locking member 45 is of a shape such that at least an edge obtained by intersection of surfaces 46 and 47 and engaging in the locked position with the lower side of the U-clasp 23 remains in contact with the lower side of the clasp 23 during tilting of the element 29. This takes place, for example, as shown in Fig. 5, in which the surface 46 is a flat surface making an angle a with the surface 47 which is the complement of an angle 19, that is the angle through which the surface 47 has been tilted.
  • the locking member of lever 30 is of a similar shape. Owing to this particular shape of the surface 46 1t 15 ensured that each part of the switching elements exhibits a component of movement which is opposite to the corresponding direction of sliding as long as the edge of the surface 46 slides along the lower side of clasp 23.
  • the terminus of the element is indicated by 48 in the case of the element 29, thus in Fig. 3 is farther away from the lower side of clasp 23 than in Fig. 4.
  • the displacement in the direction of sliding of the element is during tilting oppositely directed to the preceding or subsequent sliding movement.
  • the U-clasp 23 comprises, at each end, a prolongation 52 projecting from the extensions 26, 27, respectively. Between the prolongations 52, a lever 54 is pivotally ar ranged on a shaft 53. The lever 54 is maintained in a rest position by a spring 55 and an abutment 56 provided *ing movement. posed on the shaft, the magnitude and the direction of the "displacement resulting from the tilting movement 3 on "a la'teral'p'art 52, which rest position is chosen to be such that the points 48 just engage the lever 54 in the locked positions of the elements 29 and 31 The lever 54 occupies the same position when the buttons are released.
  • the surface 46 it is advantageous for the surface 46 to have a shape such that the shifts of all parts of the element resulting from tilting is sufficient to control the switching mechanism.
  • the present invention is not limited to the use in connection with a demagnetising device. It is also independent of the manner in which the sliding movement of the switching element is transmitted, neither is it essential for the edge which during tilting slides along the lower edge of clasp 23 to be located in the surface 47 and hence at the end of the surface 46, though the maximum stroke is thus obtained.
  • a push button device as set forth inclaim 1 further comprising an elongated lever engaging at one end :said switch mechanism, means pivotally mounting said lever on said frame for transmitting the movement of said switching element.
  • a push-button device comprising 'a carrier plate, a frame member secured 'tos'aid carrier plate, at least one switching element having -a locking portion and 'slidable in said frame member, said locking portion being areentr'ant part having opposite sides angular-1y positioned relative to each -other,'-the distance between said opposite sides.
  • a switch mechanism associated withs'ai'd push-button device “and controlled by the movement of said switching element, the latter being slidabl'e in a direction substantially transverse to said switch mechanism to actuate the same and tiltable about an axis substantially perpendicular to the direction ofsliding to further actuate said 'switch'mechanism while said switching element is locked against further sliding movement by said locking portion.
