Description

The present invention relates to the field of automatic control of

movements, in particular by

  persons with disabilities, and relates to a rotating apparatus

automatic pages.

  Currently, people with disabilities can only read newspapers or books with the help of third-party

  in their surroundings, to turn the pages.

  This procedure is, however, very alienating for the patient and very demanding for the person taking care of the patient, the two having to continually be one in the presence of the other. In particular, especially in the case of books, it is often necessary to maintain the pages

in open position.

  The present invention aims to overcome these disadvantages.

  It has, in effect, a rotating apparatus

  automatic pages, characterized in that it is essential

  consists of a chassis in the form of a light console-

  inclined relative to the horizontal, on which is mounted a pivoting support support of a frame for receiving a book or a newspaper, by a device for maneuvering the pages controlled in displacement by inverter relays, by limit switches, by an optical control cell, by an electrical outlet and by a

  switch on and off.

  The invention will be better understood thanks to the description

  Hereinafter, which relates to a preferred embodiment, given by way of non-limiting example, and explained with reference to the accompanying diagrammatic drawings, in which:

  FIG. 1 is a perspective view of a device in accordance with

  me to the invention; FIG. 2 is a plan view of a newspaper receiving frame, and FIG. 3 is a plan view showing a slide rail.

  maneuvering pages for pound and another for newspaper.

  According to the invention, and as shown more particularly by way of example, Figure 1 of the accompanying drawings, the automatic turning machine is essentially constituted by a frame 1 in the form of a desk slightly inclined with respect to the horizontal, on which is fixed a pivot support 2 for supporting a frame 3 for receiving a book or a frame 4 for receiving a newspaper (FIG. 2), by a device 5 for maneuvering the pages, which is controlled on the move by inverter relays 6, by limit switches 7, by an optical control cell 8, by an electrical socket 38, and by an on / off switch.

stop 33.

  The frame 1 carries, at its front part, the pivoting support 2 by means of a bracket 9, and at its rear part the operating device 5 by means of two end mountings 10, as well as the inverter relays 6 housed in a protective casing 11, and an electronic control unit 12 for controlling the intensity of the luminous flux and for detecting changes in this flux, of the optical control cell 8, which is advantageously fixed on

  one of the uprights 10 of the operating device 5.

  The pivoting support 2 is fixed on the bracket 9 by means of a hinge 9 ', and consists of a plate

  13 provided on its upper face with two studs 14 of posi-

  3 and 4 frames and a hole 15 for passing a fixing screw of said frames on the support 2, this plate 13 being provided on its underside, near the end opposite the hinge 9 'd' a support 16 for a spring element 17 which tends to tilt the plate 13 around the hinge 9 ', this element 17 being maintained

  in the non-use position by means of a slide lock

health 18.

  On the opposite side to the plate 13, the hinge 9 'is provided with an adjustable stop 19 allowing a pivotal adjustment of said plate 13, and, in addition, the hinge

  9 'is mounted in a height-adjustable manner by sliding

and tightening on the square 9.

  The frame 3 for receiving a book is constituted by a board that can be fixed on the support 2,

  while the framework 4 for receiving a newspaper is constituted

  killed by a fixed mounting bracket 20 on the support 2, and by a sliding member 21 guided on the support 20 and tending to press the central part of the log against a median cross by the action of springs 22, or other elastic elements.

  The device 5 for maneuvering the pages is

  killed by strips 23 to be inserted between the pages to rotate and mounted at their ends on a guide pin 24 provided near one of the uprights 10, these strips being movable on the axis 24 under the action of a spring Pressing a support and guide member 26, which can be immobilized in the compressed position of the spring by means of a sliding lock 27 guided in the upright 10, the strips 23 being held on the end of the axis 24 at by means of an eclipsable latch 29, and by a device

  28 extraction and displacement of the strips 23.

  This device 28 for extracting and moving the strips 23 is constituted by a carriage 30 movable parallel to the support 2 on transverse guides by means of a screw assembly 31 nut 32 driven by a not shown electric motor driven by pulses of the

  electronic box 12, and provided with a stop 33 of action-

  the retractable lock 29, a finger 34 driving a strip 23 cooperating with a lug 35 provided under the stop 33 and penetrating into a groove 36 of the strip 23 (Figure 3), and a stop 37 d activation of contacts

  end-of-run 7 mounted on each amount 10 and

  the inverter relays 6 determining the direction of rotation

  drive motor assembly screw 31 nut 32.

  The strips 23 (Figure 3) are advantageously at least two different lengths, the shorter 23 'being intended to be inserted between the pages of a book, and the longer 23 "being inserted between the pages of a newspaper , and they are preferably made in one

  transparent material so as not to disturb the reading.

  The apparatus according to the invention operates as follows: After setting up a book on the frame 3 or a newspaper on the frame 4, the strips 23 are inserted between a certain number of pages of the book or of the newspaper and

  threaded on the axis 24, the support member 26 being immobilized

  The spring element 17 is then released by means of the latch 18, the latch 27 is withdrawn, and the plate 13 of the support 2 tilts upwards until the upper ruler comes into abutment against the latch. retractable latch 29, and the apparatus is turned on by means of the switch 39 At the end of reading of the page of

  right, the user modifies the luminous flux by

  member or head in said flow of the optical control cell 8, whose electronic housing 12

  sends a start pulse to the motor of the assembly.

  The carriage 30 then moves the retractable latch 29 thus releasing the slider 23, and by means of its abutment 37, the slider 30 is moved 32 to the slider 32, which is moved to the right above the upper slat 23. simultaneously actuates the corresponding end-of-travel contact 7, which controls a switching of the inverter relays 6 having the effect of reversing the direction of rotation of the motor and therefore the direction of movement of the carriage 30 towards the opposite end-of-travel contact 7, the carriage carrying in its stroke, by means of the finger 34 and the pin 35, the strip 23, which is guided on its lower face on a slide 40 secured to the uprights 10, this slide having, on the opposite side to the axis 24 guiding the strips 23, near the upright 10, a recess 41 ejection

  strips before the return journey of the carriage 30.

  After ejection of the strip 23, the carriage 30 actuates with its stop 33 the end-of-travel contact 7, which reverses

  again, through the relays 6, the sense of displace-

  The carriage 30 can be interrupted at any time by modifying the luminous flux of the cell 8 by the user. Thus, it is possible for the user to stop the motor when the strip is on the left page. of the book to ensure a better maintenance of the pages Under the recess 41 of the slide 40 can advantageously be placed an inbox and

storage of the strips 23.

  Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications remain possible, particularly from the point of view of the constitution of the various elements, or by substitution of technical equivalents, without departing from of the field of protection of the invention.
