Definitions

  • the invention relates to a keyboard consisting of a chassis provided inter alia with an elongated key, for example a space bar, means for sliding this key, and a spreader intended to prevent the key from being pressed sideways, spreader oscillating about an axis linked to the chassis and perpendicular to the direction of said sliding, and comprising at least two pins, each sliding in a slot formed in the key perpendicular to the direction of said sliding.
  • Keyboards according to the invention are used for example in data processing equipment such as minicomputers.
  • Space bars provided with spreaders according to the preamble above are present in a commercially available computer keyboard.
  • the spreader pins are engaged in key slots and the spreader axis is held by rigid intermediate parts, themselves attached and fixed to the chassis by clipping.
  • the assembly of this system is possible by bringing together the key, the spreader and said intermediate parts on the chassis. To mechanize this assembly, a complex system would be necessary to hold and position all these parts together.
  • disassembly is only possible by accessing the underside of the chassis beforehand to release said intermediate parts.
  • the invention aims to provide a keyboard whose assembly and disassembly are greatly facilitated.
  • the lifter can be put in place on the chassis in advance, and the assembly is completed by the only addition of the bare key, which suffices to press down forcefully to put it in square. Disassembly is also easy since it suffices to pull hard enough on the key.
  • a keyboard according to the invention is notably remarkable in that, each slot being open at one end to allow entry of the spindle, the key is provided with an inclined plane leading towards the opening of the slot , in the direction from the chassis to the key, and the connecting means between the axis of the lifter and the chassis comprise an elastic part to allow movement of said axis in the direction which allows the pins of the lifter to follow the inclined plane and to enter the slot.
  • the opening of the slot is turned towards the outside of the button.
  • the lifter is fixed to the chassis by at least one elastic hook whose clearance is sufficient to allow the introduction of the pins into the slots.
  • This hook advantageously comprises a folded part intended to increase its effective length, and consequently its elasticity and its clearance.
  • the elastic hook is advantageously molded in one piece with the chassis, made of plastic.
  • space bar On the keyboard of FIG. 1 is indicated at 4 the elongated key called space bar, which is concerned with the invention.
  • the key is provided with known sliding means 5, 6 which are not part of the invention. They comprise a central tube 5 intended to slide in a barrel 18 carried by the chassis, and cylinder parts 6 which serve to trap a return spring (not shown) and to fix the key by being hooked by lugs to a relief 21 formed around the barrel 18.
  • This barrel is held in the center of an annular hole 20 by four fins 19.
  • the elements 6 can slide in this annular hole and the fins pass between the elements 6. It is also the tube 5 which presses on electrical contact means not shown.
  • the lifter intended to prevent the key from sinking crookedly consists here of a steel wire whose diameter is approximately 1.5mm, of which part 8 constitutes an axis of oscillation, and each end of which is folded twice at right angles to form, at each end, a pin 9 parallel to the axis 8, that is to say here horizontal, and therefore perpendicular to the direction of sliding which is here vertical.
  • the key 4 has at each end a tab 15 in which is formed a slot 3 perpendicular to the direction of sliding, that is to say horizontal here.
  • the slot 3 is open at one end which is here turned towards the outside of the button.
  • the axis of the swinging spreader is linked to the chassis by hooks 1 which are shown diagrammatically at the spreader, and shown in more detail below.
  • the hook 1 is arranged opposite a relief 12 so as to trap the part 8 of the lifter between the hook 1 and the relief 12.
  • a vertical wall 10 makes it possible to press against it the part 7 of the legs 15, as the arrow 17 suggests, to prevent the key from turning around a vertical axis, and a rectangular hole 11 allows the legs 15 to sink, when the key is pressed .
  • the legs 15 are provided with an inclined plane 2, the role of which will be better understood thanks to the section of FIG. 3.
  • FIG. 3 the assembly is shown mounted, in the rest position of the key.
  • the elements already described in connection with FIG. 2 bear the same reference numbers there.
  • the chassis is indicated by the reference 13, and the spindle 9 is shown in a rest position 9A and in a position 9B which has two functions.
  • the lifter turns around its axis 8 and the spindle goes from position 9A to position 9B, while part 7 slides along the vertical wall 10.
  • the axis 8 is held between the hook 1 and the relief 12, and the lifter rests flat on the chassis. There is therefore no need to provide tools to maintain it.
  • the lugs of the elements 6 of the sliding system of FIG. 2 engage in the relief 21 of the barrel 18 and subsequently prevent the key from going back higher than the position shown in FIG. 3.
  • the effective length of the latter is increased, since from its point of connection to the chassis, it is first directed downwards, then is folded at 14 to then direct upwards.
  • the frame 13, the wall 10, the hook 1, 14 and the relief 12 are all molded together in a plastic material, for example that called ABS.
  • disassembly one way is to insert a tool that moves the hook 1 to the left, the key being pressed, which pushes the pin 9B out of the slot 3 after which we just have to leave raise the button.
  • Another means, with which disassembly is even easier, is to provide a deeper slot 3 than the normal displacement of the key requires, as is suggested by the dotted line 30. Then, it suffices to pull the key up strong enough to release the clipping 6, 21 of the sliding means, and when the bottom of the part 7 reaches the height of the top of the wall 10, the key can be released to the right.
  • the hook can have other shapes, one can imagine in particular a kind of bolt associated with a spring, like that of a lock.
  • the slot 3 can also be turned towards the inside of the key, the hook then being turned in the other direction (that is to say its elasticity would make it possible, in the case of FIG. 3, to push the lifter to the right) .
  • this solution is less favorable because it leaves less width available for the lifter, unless the latter overflows outside the key, which is not desirable.
  • a group of elements 1, 10, 11, 12 can be constituted by a small independent part which is attached to the chassis. Instead of using a relief 12 opposite the hook 1, it is also possible to provide the latter, at its end, with a sort of clamp trapping the axis of the lifter.
