Definitions
- the present invention relates to game machine, and in particular it refers to a backlighted push button for said machines.
- backlighted push buttons which are essentially constituted by a body for hooking to the game machine and for housing a sliding element, fit to carry out the opening and closing strokes of the electric connection of the push button, and supporting at its upper end a covering body housing a transparent cap allowing the light to pass through coming from a light opportunely positioned inside the sliding element.
- Said known push buttons therefore, allow to activate the main functions of the game machine and during the function, allowing the illumination of the transparent cover.
- a limitation of the known push buttons is due to the fact that the portion which is illuminated is only limited to the central portion of the push button well visible from the top of the key but not from the side.
- the main object of the present invention is to propose a backlighted push button with more than one illuminable zone so that it can be seen better and also laterally.
- numeral 1 indicates a backlighted push button for game machine, known but not shown, which is essentially constituted by a body 2, a sliding element 3, a fixing element, so called covering body 4, a cap 5 and an insert 6.
- the body 2 is hallow internally and houses the sliding element 3 with the interposition of a spring, not shown, and externally provided with a threaded zone to facilitate the hooking of push button 1 to the game machine through a screw bolt.
- the sliding element 3 is hallow internally, houses an luminous source, for example a known but not shown light bulb, and has, at its lower end, hooking means 3a to the body 2 and, at its upper end, supports the cap 5.
- an luminous source for example a known but not shown light bulb
- the covering body 4 is fixed at the upper portion of the body 2 and constitutes the peripheral visible portion of the push button 1.
- the covering body 4 is centrally provided with a hole 10 for the passage of the sliding element 3 and two peripheral slots 9.
- the insert 6, interposed between the covering body 4 and the cap 5, is shaped almost complementary to the covering body 4, is provided with a hole 11, is hooked by click to the covering body 4 and comprises conveyor means 7.
- the insert 6 is hooked to covering body the 4 in such a manner that the two inner ends 7a of conveyor means 7 are invested by a light beam R coming, for example, from the light source inside the sliding element 3.
- Each external end 7b is semi-lunar shaped complementary to the corresponding push slot 9 of the covering body 4.
- the conveyor means 7 is preferably made of light transparent material, also in several colours, and comprises a prism of internal reflection 8a, a prism of intermediate reflection 8b and a prism of external reflection 8c.
- push button 1 provides the activation of the luminous source whose light beam R beats the inner wall of the cap 5, backlighting this latter and allowing the primary lighting of the backlighted push button 1.
- the same light beam R invests the inner end 7a of the conveyor means 7 and, passing through this latter, is reflected in succession by the prisms of the internal reflection 8a, of the intermediate reflection 8b and of the external reflection 8c until it illuminates the external end 7b.
- the light source or with the supplementary light sources it is possible to illuminate the push button not only at the part of cap 5 but also in peripheral zones of the covering body 4 allowing better visible the push button also from the oblique angles-shot in respect with the longitudinal axis of the push button, because the covering body 4 is normally curved having cylindrical or spherical external surfaces.
- the main advantage of the present invention is to provide a backlighted push button with more than one illuminable zone in order to be visible not only from the top but also from the side.
