Description

The present invention relates to readers of

  documents such as maps of all types,

  directories, lists, catalogs, ephemeris and similar

  which should be consulted quickly when it comes to following a route or finding information. In many situations it is necessary to

  consult documents, maps or directories

  res. This is the case for example for road traffic,

  shipping or air transport or even for

  pedestrian Because of their size, their lack of rigidity and / or the number of their leaves or

  folds, reading these documents is difficult. The conditions

  readings are often

  precarious and may result in errors of interpretation

  may be dangerous in the case of driving a means of transport. In addition to the navigation errors that may be involved, the consultation itself of the document under the conditions just described over-mobilizes the attention of the user, which, if he himself drives the means of transport, can

cause accidents.

  These problems are well known in the fields of

  piloting aircraft or automobiles in rallies and the professionals

  of these activities generally use

  rigid reading systems on which they fix, for example

  by means of elastic cords, the cards which they

  consult and annotate. These reading boards allow

  easier handling of the cards, but they are

  while requiring little manipulation

  than to switch from one card to another, or even from one

sheet or fold to another.

  The poor reading conditions on these boards are amplified when the illumination is low, for example during night driving, and even the use of lamps

  wanders or projectors does not give complete satis-

  faction. Because of their disadvantages, such reading boards are not widespread in the general public and are offered for sale only by traders.

specialized.

  The object of the present invention is to provide a

  apparatus not having the drawbacks mentioned above.

  top, which is of great ease of use, a small footprint and a low cost, and which allows a precise and fast reading of documents of

large dimensions.

  According to the invention, this object is achieved by virtue of the fact that the document, if necessary cut into strips of equal height, connected end to end in a predetermined order to form a ribbon of great length, is subject to its two-coil ends. indifferently playing the rattle

  receiving coil and supply coil on which

  the document is rolled up, both coils being mounted

  parallel to each other and so as to be able to

  around their axes on either side of a substantially parallelepipedal support whose flat and rigid upper face forms a reading table on which the document going from one to the other

  coil, the assembly constituting a charger or cassette, the-

  said charger which can be introduced into a boot case

  both a substantially rectangular reading window through which the document carried by the loader can be accessed, said stacker further comprising means for retaining and ejecting the loader and means for rotating each of the two reels of the loader and

  circulate, in one way or the other, the

  leaves behind the window of the case.

  According to another characteristic of the invention, the part of the charger that constitutes a reading table is translucent and lighting means are placed in the botter so as to be, when the charger is introduced into the housing, located below the translucent part, thus ensuring transparency the illumination of the document consulted. Thanks to the rotary means that comprises the document reader according to the invention, it is extremely easy and quick to scroll the document behind the window of

  reading, so that the latter can be of

  -nions reduced without reading the document,

  for example, a large-scale map is hindered.

  The document reader according to the invention can be of

  smaller dimensions than a conventional reading board

  which allows the user to transport it

ter and handle it without embarrassment.

  In a preferred embodiment, the shoemaker

  the reader and charger are made of plastic

  injected tick, which makes it possible to obtain them at a very low cost. The charger, in particular, may have

  very simple forms, to understand only a few pieces

  so that his cost is minimal. It is so

  possible to build a collection of char-

  the cost of each of the packed loaders not exceeding

  as soon as the codt of the card itself.

  In addition to these advantages, the reader according to the invention makes it possible to keep documents in good condition, even after very many consultations, said documents not being

  not handled directly by the user.

  In this respect, the casement window may be provided with a transparent plastic sheet, preventing

  the direct contact of the document and the degradations that

  sulteraient. If, however, it is desired to be able to write

  on the document, the transparent sheet can be

  raised or replaced by a film superimposed with the

  document, allowing writing and erasure.

  The document reader according to the invention is constituted

  killed by a casket 1 (FIG 1) substantially parallelepiped

  dique and hollow in which is housed a charger 2

  (fig.5) also substantially parallelepipedic. The box

  tier 1 has a rectangular window 3 on its upper face 4. When the charger 2 is introduced into the

  boXtier 1, the upper flat surface 5 of the charger 2 is vi-

  or not, ensuring the protection of the document. A small

  this 6 end of box 1 is free while the other 6

  tite 7 face end of the case carries at its ends two

  knurled or knurled buttons 8 (only one of these being

  shown in Figure 1) rotating around parallel axes

  between them and the two side faces 9 and 10 of the boXtier.

  The boltier 1 itself is formed by a half

  upper boltier 11, which has the window 3, and a lower half-casing 12, the two half-housings being in contact with each other along a joint plane 13 on their periphery. The upper and lower half-casings 11 and 12 have, near the lateral faces 9 and

  10, cells 14 (FIG 3) arranged in pairs on one another

  above the other, one in the upper half-stack and the other in the lower half-boltier. The ends 15 of four elastic and semi-cylindrical clips are housed in the cells 14 by overlapping the joint plane

  13 to keep the half bowl bolts in the opposite position.

2462272

  The upper half-boltier 11 bears on its upper face

  4 and close to the end face 7 a button-

  push 17 whose functions will be explained later.

  The left and right ends of the end faces 71 and 72 respectively of the half-housings 11 and 12 comprise half-bearings 18 and 19 which form, when the half-housings

  are assembled, two bearings 20 for the buttons 8.

  The half-box 12 (FIG 2) is provided with projections 21 on its inner face 22, said projections being adapted to maintain in position an electric battery 23 (FIG 6). The inner face 22 also carries metal bars 24,

  and 26 arranged in series which constitute a circuit of

  feeding, from the poles of the battery 23, an incandescent lamp 27 fixed substantially in the middle of the inner wall 22 of the half-housing 12. The end 28 of the bar 24 and the end 29 of the bar 25 are left free from each other, a contact,

  ensuring the passage of electric current, which can be

  by flexing said ends toward each other.

  The ends 28 and 29 forming an electrical switch are arranged close to the inner face of the wall 72 of the

  lower half-box 12, and so as to be just in-between

  under the pushbutton 17 carried by the upper half-housing

11.

  Thanks to an elongated slot 17 '(FIG 7) in which

  it is housed, the push-button 17 can be moved long-

  tudinalemen.t relative to the case. When he is moved

  in the Y direction, its lower part 30 comes to the con-

  tact then pushes the end 29 of the bar 25 towards the ex-

  tremité 28 of the bar 24, the bar 25 deforming elastically. An electrical contact is thus made, this

  which causes the illumination of the lamp 27.

  In the bearings 20 formed in the housing are shown

  buttons 8. These bearings 20, consisting of two half-

  bearings each carried by a half-casing, have three

  successive cylindrical bearings 40, 41 and 42 (FIG 8), each

  one of the staves having a diameter smaller than the diameter of

  the previous. The range 40 of larger diameter is

  killed near the outer side of the case. Between the por-

  40 and 41 is formed a groove 43 circular of a

6 462272

  internal diameter greater than the diameter of the span 40.

  In this groove 43 is housed an annular flange 44

  which is shaped on a single hollow cylindrical sleeve 45

  block with a button 8 having substantially the shape of a mushroom, provided with a cylindrical cap 46 of axis 47,

  the hollow sleeve 45 acting as a foot. Through cooperation

  rim 44 and groove 43, the button. knurled is held in position in the bearing 20 and is movable in

  rotation, the bearing 40 ensuring the guiding of the sleeve 45.

  The internal cylindrical face 48 of the sleeve 45 has at its free end 49 a smooth cylindrical bearing surface 50

  diameter greater than the diameter of the cylindrical

  48. This cylindrical wall 48 has grooves 51

  (Fig 9) regularly spaced on the periphery of the

  King 48 and parallel to his generators. In the volume

  free dull sleeve 45 is housed a sleeve 52 cy-

  lindrique and hollow bearing on its periphery longitudinal ribs 53 which cooperate with the grooves 51 of the sleeve 45. The sleeve 52 is thus locked in rotation but

  is free in translation relative to the sleeve 45 of the

  the diameter of the bearing 50 of the sleeve 45 is sensitively

  It is equal to the diameter of the bearing surface 41 of the bearing 20, the two bearing surfaces 50 and 41 thus extending axially to one another. In the annular space constituted by these two bearing surfaces 41 and 50 is housed an annular ring 54 of rectangular cross-section, formed at mid-length of

  the sleeve 52 and on which abut the ribs 53.

  the freedom of movement in translation of the sleeve 52 is thus limited by the abutment of the lateral faces of the ring 54 against the sides 55 and 56 of the annular recess limited by the bearing surfaces 41 and 50. Beyond the ring 54, the sleeve 52

  is extended by a smooth cylindrical portion 58 of a diameter

  be slightly smaller than the diameter of the bearing 42, the latter guiding the sleeve 52 in translation. The end 57 of the sleeve 52 located opposite the knurled knob 8

  has an annular cap 60 and a plane of larger diameter

  meter that part 58 of the socket. the end face 59 of the cap 60 has radial grooves 61 (FIG. 10) angularly arranged in a regular manner. In the axial bore 62 of the sleeve 52 is disposed a coil spring 63, one end 64 abuts against the inner face 65 of the button 8 and the other end 66 abuts against the inner face 67 of the cap 60 of the sleeve 52 Spring 63 has

  effect of protruding the sleeve 52 carrying the cha-

  skin 60 towards the inside of the housing relative to the bearing, the ring 54 abutting against the edge 56 of the scope

  41 and thus limiting the protrusion of the socket.

  The upper face 67 of the button 8 has a slot

  diametrical 68 which extends on the cylindrical side

  69 of the button by a slot 70 parallel to the axis of the button.

  In these slots 68 and 70 is housed an angled element 71 connected at its end 72 to the knob 8 by a hinge 73 located at the end 74 'of the slot 68 opposite the slot 70. By the play of this hinge 73, the angled element 71 can move from a first position in which it is

  housed in the slots 68 and 70 of the button at a second posi-

  remote control where it forms a crank allowing the knob to be turned by grasping the free end of the square. The magazine 2 intended to receive the document in front of

  to be consulted is constituted by a substantially parallel body

  the epipedic 80 whose large upper face 5 serves as a reading table and whose large lower face was removed. the material chosen to make the charger is a translucent plastic material. In the small face

  end of the magazine is provided with a rectangular recess

  re 82 opening. In the middle of the edge 83 of the upper face

  5 and the small end face 87 is provided a cell 84 limited by a rim 85 (FIG 7) extending on a slope

  soft to the end face 87 of the charger.

  On both sides of the loader and in the

  of its end faces 87 and 88, protrude from the

  89 and 90. the ears 90, which extend the end face 87, have a circular hole 91, and the ears 89, which extend the end face 88, pre-feel on their

  inner face 92 a circular grain 93.

  the magazine 2 is equipped with two bobbins 94 with axis 95 terminated by two circular flanges 96 and 97 which bear on their outer side 98 a cylindrical rim 99, of the same axis as the bobbin, having an internal bearing surface 100 and

  an outer bearing 101 cylindrical and smooth.

  The outer flank of the flange 97 (FIG 8) carries, in its central zone 200 limited by the flange 99, trapezoidal grooves 102 (FIG 10) arranged radially and in conjugate form of the ribs 61 of the cap 60 of the socket

52 sliding in the button 8.

  The coil 94 is mounted on the charger cooperatively

  on one side, the cylindrical grain 93 of an ear 89

  with the internal cylindrical bearing surface 100 of flange 99 of

  than 96, and on the other hand by cooperation of the

  the outer lindrique 101 flange 99 of the flange 97 with the hole 91 of the ear 90, the introduction of the coil being elastically deforming slightly ears 89 and 90, which then block the coil in position while allowing it a rotational movement around its axis.

  A coil 94 being mounted on each side of the

  2, a document having the shape of a strip of great length and width substantially equal to the dimension between flanges of the coils, is fixed by its ends to the two coils respectively passing above the reading table 5 of the charger. the document is wound on the reels until it is properly stretched over

said reading table.

  How to use the document reader according to

  the invention will now be described.

  The magazine 2 carrying a document wound on its coils is introduced longitudinally into the casing 1 by its end face 6 left free. the front of the charger at the edge of which is the cell 84 is introduced first. Thanks to the recess 82 of the end face 81, the circulation of the loader in the casing is not impeded by the presence of the electric battery 23 and the lamp

electric 27.

  At the end of the race, the bobbins 94 of the loader are

  wind in the axial extension of the sleeve 52 controlled by the button 8. As has been seen above, this sleeve 52 is protruded by the spring 63. The ribbed cap 60 of the sleeve 52 comes into contact with the flange 97 of the coil by sliding in the inner surface 100 of the flange 99 carried by the coil. As a result of this contact, the ribs 61 and

  the grooves 102 of conjugate shapes are made to co-operate

  rer. The introduction of the loader continues, the spring 63 is compressed and the sleeve 52 moves backwards until the loader is in its full introduction position. With the spring 63, the ribbed cap 60 of the sleeve 52 is

  applied firmly against the face 59 of the spool 94.

  At the end of introduction of the magazine, the rim 85 of the cell 84 cooperates with a pin 201 (FIG 7) carried by

  the inner face of the casing, the cell 84 thus coming

  click on the pin 201, by elastic deformation of the edge 86 of the cell. Thanks to this clipping, the charger

  is stuck in position in the stacker.

  Through the window 3 of the housing it is possible to consult the

  cument, carried by the loader who is supported by the table

reading 5.

  The rotation of the button 8 causes, by cooperation of the grooves 51 of the button and the ribs 53 of the socket

  52, the rotation of the latter which, being applied fer-

  against the flange of the flange of the coil, drives the coil in rotation through the cooperation of the ribs 61 of

  the sleeve 52 and grooves 102 of the coil 94.

  When we want to scroll the document in front of the

  reading window, just turn one of the two

  8 controlling the rotation of one or the other coil,

  according to the direction in which one wishes to scroll the

  cument. When the document is fully wrapped or unwound

  on a coil, there is no risk of damaging it, for example

  This is because, when one of the coils is locked in rotation for any reason, the ribs 61 and the grooves 102, the sides of which are inclined, act as an escapement. Mechanical ment, the sleeve 52 retreating by wedge effect by compressing the spring 63. A ratchet effect is thus obtained. If you wish to illuminate the document, simply push the button 17 in the Y direction (Fig. 7), which

  causes the electrical contact described above and the

  The magazine's reading table is translucent, the back of the document placed on the reading table is illuminated and the

  document is enlightened by transparency. -

  When it is desired to eject the charger from the case, simply push the button 17 in the opposite direction Y. The lower part of the button 17 then comes into contact with the flange 86 of the cell 84, which is pushed down and deforms elastically until release the pin 201 from its stop in the cell 84. Under the action of the springs 63 which act on the sockets 52, the charger

  ejected from the casing, the sockets 52 taking up their position

  projecting towards the inside of the housing with respect to

bearings 20.

  To make reading a large document easier

  dimensions, for example a map, said document is

  tagously cut out (Fig. 11) into strips of width equal to the width of the rolls, then butt-to-end (Fig.12) and rolled up in a magazine. To facilitate the reading of the card 180 and in particular the passage from a point 181 of the card situated on the edge of a strip to a next point i82 which corresponds to it, it is advantageous to wear on the edge 183 of the strip a graphic 184 or a color that

  indicates by correspondence part 185 of the following

  previous or next to which you must refer by scrolling through the document with knurled buttons to find the rest of the document. If it is desired to write on the document, the window 3 of the casing does not carry a transparent sheet, and the document is advantageously coated or

  lined with a transparent film allowing the writing and the ef-

facement.

  In an alternative embodiment, the control of the rotation of the coils is ensured by an electric motor with

  inverter, placed in the housing and replacing the buttons 8.

  The power supply of this electric motor is ensured by the

  battery mounted in the case or by an external energy source

  the latter, which can also supply the lighting means.

  It is clear that if the document presents itself

  In the form of a ribbon of height substantially equal to the width of the reels of the loader, it is not necessary that it be 2462272

  cut it into strips and connect them end to end.

  Such a document can be housed in a charger without

preliminary treatment.
