Definitions

  • the subject of the invention is a waterproof modular keyboard with a tactile effect.
  • this type of keyboard has the major drawback of not having a stroke allowing the operator to realize without display means, by simple tactile sensation, if his action has been taken into account by the machine connected to the keyboard.
  • the invention combines the advantages of these different keyboards, while eliminating their respective drawbacks.
  • the invention enables a reliable, waterproof, easy-to-maintain, robust, modular keyboard to be produced at low cost.
  • a keypad intended to be mounted in the housing of an apparatus and comprising: a printed circuit board serving as support and connection means for a plurality of modular switches housed in housings, placed side by side side by side and each actuated by a push-button to receive and transmit the movements of a cooperating key, deformable means being associated with each push-button-switch assembly to communicate a tactile sensation to the user, an insulating, rigid spacer of generally planar shape, fixed to said card and forming a plurality of through cells housing the respective housings, is characterized in that the walls of said cells have outer edges and an internal surface substantially perpendicular to said card and having retaining means; that said deformable means comprise a membrane which covers the cells and is fixed to said outer edges, the portion of membrane which closes each cell being provided with an opening; and by the fact that each push-button assembly comprises an outer part and an inner part to the corresponding cell, connected together by a part which passes through the opening and is fixed to the membrane, said inner part
  • Fig. 1 represents a set of keys 8 resting on a membrane 1 partially removed to reveal a spacer 3 on which the key-membrane assembly rests.
  • This modular honeycomb spacer 3 obtained by molding comprises a plurality of cells 30 arranged in rows and columns.
  • This plurality of housings or cells of square shape are defined by partition walls 31 having precuts 32 so as to modify the dimension of a cell and to obtain cells having several modules of length.
  • contact modules or indicator modules are available depending on the type of keyboard that one wishes to achieve and, in cooperation with these contact modules, keys in square shape comprising the alphanumeric characters or other signs corresponding to the keyboard that we want to achieve.
  • all or part of the modular honeycomb spacer is used.
  • this spacer in combination with the modular elements constituting a keyboard makes it possible to obtain keyboards that are easily adaptable to demand.
  • Fig. 2 shows an embodiment of a waterproof modular keyboard with tactile effect and a relatively large stroke, in which there has been mounted on a support constituted by a printed circuit 4, contact modules 7 at the locations corresponding to the housings of a spacer modular 3 which is fixed on the printed circuit by means of screws 22 for example.
  • the modular spacer 3 can also be fixed to the printed circuit by crimping or any other fixing means.
  • This modular spacer 3 comprises partitions 31 separating the housings from the precuts 32 to detach several partitions and obtain housings with dimensions adapted to the keys and, in addition, housing covers 33 connected to the partitions delimiting the housing, by a thin web 34 allowing by pressing on the cover, detach the cover from the grid and obtain an opening at the location chosen to place a button 30.
  • the partitions of the grid have a flat lower face in contact with the printed circuit, an upper face in which is formed a longitudinal groove 35 and two lateral faces each comprising a vertical portion 36 and an inclined portion 37 forming with the vertical portion 36
  • the face of the covers, outside the housings, is in a plane parallel to the plane in which the upper faces of the partitions are situated.
  • a membrane 1 made of polyurethane or any other elastic and waterproof material that can be easily molded has bosses 100 in the form of a trunk of pyramid 105 with a square base, the upper base of which cooperates with a key or rests on the upper face of the associated cover in the case where there is no key, and whose lower base is secured to the spacer by longitudinal and transverse ribs 101 which are fixed in the grooves 35 of the spacer 3 by gluing, crimping, welding or any other suitable means .
  • the upper base of the membrane boss has a bead 102 sealing with the button 8 which is mounted on this upper base after having made a cruciform notch 107 in the membrane, as shown in FIGS. 10 and 11, to allow the passage of the latching head 84 of the button 8 with the assembly part 11, comprising a flange 110 which limits the movement of the part 11 coming into abutment against the shoulder 38.
  • the flange also cooperates with the faces vertical 36 of the partitions closing the housing to form a means for guiding the button when the latter moves vertically.
  • the seal between the keyboard and the housing 12 of the device using the keyboard is ensured by tightening the membrane against the housing 12, for example by means of a device such as that shown in FIG. 2 comprising a nut 122 welded to the housing, a flange 120 and a screw 121.
  • Figs 3 and 4 show a contact module used in the keyboard of fig. 2, comprising a polycarbonate housing 74 of circular shape provided with two holes in the bottom of the housing to allow passage to two pins 77, 78 of conductive material, provided with contact heads.
  • the bottom of the housing also includes two bosses 70, 71 fig. 4.
  • a contact blade 75 constituted by a thin sheet of conductive material, comes to rest in the housing bearing on the bosses 70, 71 and the pin 77 so that at rest the electrical connection between the pins 77 and 78 does not is not established, while in the working position it will be established.
  • a thin waterproof polycarbonate film constituting a membrane 76 is bonded or welded to the housing 74.
  • This type of contact module has the advantage of not having a tactile effect due to the passage of a hard point. This contact module therefore avoids to superimpose a tactile effect due to the module, to the tactile effect of the boss 105 of FIG. 2.
  • the housing 74 has on its periphery a circular rib 79.
  • Fig. 5 shows the production and mounting of a multiple key, for example double.
  • a double key 81 of length equal to twice the length of a single key plus the distance separating two adjacent keys is produced.
  • This double key has two latching heads 84 which are mounted by means of two assembly parts 11 on the membrane secured to the grid 3 from which an intermediate partition has been removed at the place where the key is to be mounted. double.
  • Fig. 6 shows a variant of the second method of mounting a unitary button with label housing.
  • the partitions 31 of the spacer 3 do not have a shoulder 38 but have on their vertical parts 36 an extension 360 constituting a circular opening in which a contact module is fixed by snap-fastening of the rib 79 with a corresponding groove 361.
  • the connecting piece 11 does not have a collar, but a guide surface 112 and is assembled by snap-fastening with the button 8 label holder, constituted in a manner known per se by a body 85 comprising in a housing 88 a label protector 86 in transparent material and a label 87.
  • a tongue 104 makes it possible to remove a piece of membrane precut according to the precut 103 of square shape and to obtain an opening 106 which allows the mounting of a key as represented in fig. 6.
  • Fig. 7 shows a top view of a square shaped button having in a corner of the button a transparent circular window 83 for an indicator and a label protector 86 of circular shape adapted to the shape of the finger.
  • Fig. 8 shows a diagonal sectional view of the button with indicator mounted on the keyboard in a housing comprising in addition to the contact module 7 a support 51 for light-emitting diode 6 mounted in an opening 41 formed in the printed circuit.
  • the assembly piece 11 mounted in the housing includes a skylight 111 opposite the diode and the transparent window provided on the button.
  • Fig. 9 shows the mounting of a fixed indicator in an opening provided for a key in which a support 51 for light-emitting diode 6 has been mounted on the printed circuit.
  • a cabochon made of transparent material 23 of shape suitable for cutting the membrane and comprising on its lateral faces 25 a groove 24 in which the bead 102 of the membrane is clamped by an internal collar 114 provided on the assembly part which just snaps onto the cap.
  • An outer flange 113 and the lateral faces 25 prevent any movement of the cap relative to the grid.
