Definitions

  • the present invention relates to push button assemblies, and particularly, but not exclusively, to illuminated push button assemblies for use in amusement or gaming machines.
  • Conventional push button assembly as used with an amusement or gaming machine typically comprise a push button, a housing, a lamp and switch unit, and an actuating structure with a spring.
  • GB 2350722 A discloses a push button assembly of this kind.
  • the push button comprises a translucent disc, a transparency and a fitted lens cap.
  • the housing is an open ended tubular structure with a flange around one end defining a bezel.
  • the push button is movably retained within the flange and the lamp and switch unit is removably attached to the opposite open end of the housing so that the lamp is within the housing for illumination of the button and the switch is outside the housing.
  • the housing is passed through an aperture in a panel of the machine with the flange on the outside and a nut is screwed onto the tubular structure against the underside of the panel to hold the housing firmly attached to the panel.
  • Conventional push button assemblies for amusement or gaming machines are typically illuminated e.g. by an internal lamp, to attract attention to the button and to indicate the current functional status of the associated switch with regard to the game played with the machine.
  • the button may be illuminated with a steady or flashing light to indicate that the button can be pressed to initiate game play, the button otherwise being non-illuminated or differently illuminated. Illumination may be by means of an LCD or OLED light source or sources.
  • Push buttons illuminated by OLED or LCD sources typically have small viewable areas when compared to the overall button size.
  • the OLED or LCD screens are arranged inside the push button under the lenscap, and display the images only to the size of the viewable area of the LCD or OLED itself. This typically leaves a non-illuminated border area on the push button.
  • GB 2350722 provides a push button assembly where the button is surrounded by an external bezel that has an array of illuminable LEDs beneath it. Light is transmitted by light conducting elements to the bezel to provide a display of light spots which can twinkle or alternate to give an attractive changing pattern.
  • a disadvantage of the above described illumination means is that there is an area at the edges of the push buttons that cannot display an image. Additionally, a further disadvantage is that the illumination means is placed in a position where it typically provides the surface pressed by the user, or directly in contact with the top surface of the button and is separated from said button surface by a plastic film. As the illumination device is therefore constantly absorbing strikes by the user when in use, it is required to be particularly robust. Even so, the illumination device is therefore liable to failure which requires the time consuming and costly maintenance of the games machine by replacement of the illumination device. This replacement and maintenance may typically be achieved only by the replacement of the entire push button assembly.
  • Embodiments of the present invention seek to provide illuminated push button assemblies, and in particular, but not exclusively, push button assemblies for use in gaming or amusement machines which provide more varied illumination arrangement for a push button assembly to facilitate a greater versatility of uses for the assembly.

  • the appearance of the button can be easily changed by changing the projected image.
  • the appearance obtained this way conveniently closely represents the appearance of a traditional push button in which a printed insert bearing an image is placed on a surface of the button and illuminated from behind.
  • provision of a rear projection surface enables any means for projecting light, and in particular an image, onto the surface to be spaced from the push button so that force applied to, and movement of, the push button is not transferred to the projection means during use of the button, reducing the risk of damage to the projection means.
