Abstract

The automatic page turner has a base plate (1) that may be on a table or a stand, a flat support surface (2) for the book. There is an arm (14) that rotates about an axis parallel to the surface of the support, and close to the surface, together with a drive (5-8) for actuating the arm in rotation. A user control (39) is provided to control the operation of the drive, and a suction device (17) is fitted to the arm at some distance from the axis of rotation. The arm is positioned above the page to be turned and the suction lifts the page and holds it while the arm displaces the page. The suction is then released and the page falls to its new position.

Description

 This page-turner must be used to turn magazines in various large formats because it is adjustable.

 Can be used by disabled people absent from their members or simply to turn pages alone without touching the magazine.

 Can be used especially for musicians to turn the pages of the musical scores placed on their desk as soon as they make music. For these, there will be additional options to keep the pages attached to the desk under various circumstances, for example when there is a music concert outside and a little breeze of wind might turn the scores page; fixings are provided so that it does not turn alone with the wind.

 PL 1/4 Fig. 1 includes the page turner in perspective.

 PL 2/4 Fig. 2 includes the page viewer turned upside down.

 PL 3/4 Fig. 3 comprises the plate, the actuator and its full-size mechanism of the page turner.

 PL 4/4 Fig. 4 has the case closed with the inner page turner and FIG. 5 the open case with the visible page turner on a desk ready for use.

 This automatic page turner consists of two plates (1) and (2) superimposed one above the other with 4 height-adjustable support columns.

 The bottom aluminum plate (1) is used to hold the entire mechanism of the page-turning device on the edge.

 The top plate (2) is used to hold a magazine, book or sheet music.

The turning device attached to the edge of the bottom plate
(1) consists of an aluminum plate (4) with a grooved design (5) for the movement of the arm (14) which turns the page. In this plate (4) there is fixed a toothed pulley (6) connected with a toothed belt (7) to the toothed pulley of the motor (8) of 12 V and 220 V.

 Next to this plate (4), there is fixed a jack (12) which allows by its movement to feed a suction cup which sucks the page of the magazine and turns it.

 The contents of this page turner are contained in a case designed for this purpose which will always remain in it even at the time of its use and the whole is placed on a desk.

 The groove (5) on the plate (4) is used to make an arm movement to vacuum the page.

 The motor (8) feeds the belt (7) the pulleys (6), the actuator (12) being actuated sucks air which, connected by a flexible rubber tube (13) to the arm (14) and at the end a suction cup (17) fixed on a support (29) sucks the page to turn it.

 All the connecting rods, movement arms, support cylinders and support arms of the plate are used for the movement and operation of the device.

 The notebook fixing magnets (16) are used to fix the magazine on the spot so that it does not move when the page turns sucked by the suction cup.

 The cylinder (21) supporting the movement arm (22) serves to keep all the cylinders (27) movement rod (23), cylinder (24) well aligned and directed in alignment in their course along the groove (5) of the main cam plate (4).

 For musicians, there will be options (15) to add to maintain the sheet music when there is wind in fiber air concerts.

 The motor (8) which turns everything, will be actuated by one or more push buttons (39) where the user would be best suited to use it ex foot, hand, elbow, knees, etc.

 The whole of this page-turner is designed so that when you have finished playing and want to put everything away, music stand, accessories of the page-turner, books, magazines and scores, everything fits inside between the two plates (1) and (2) and thus close the case.

 The two plates (1) and (2) Fig. 1 are made of aluminum or plastic for the advantage of their rigidity and lightness.

 The 4 adjustable columns (3) are formed so that the top plate can be adjusted according to the desired height necessary for the operation of the turner.

They are made up
The column is in two parts. The lower part would be a cylinder pierced at its center of its diameter so that the other smaller upper cylinder slides inside a screw placed on the larger cylinder would block the upper cylinder which slides at inside and thus adjust the height of the plate (2) for the thickness of the magazine.

 These cylinders, both the bottom and the top, are perforated and threaded at the central edge of their ends in order to be able to fix them to the two plates (1) and (2).

 The main cam plate (4) Fig. 1, 2, 3 also made of aluminum for its lightness is made in such a way.

There is a grooved slot (5) there. 1 used to roll inside a bearing fixed to an axis and cylinder (27) but the cylinder (27) is kept straight in its movement along the groove (5) thanks to the movement support arm (22) by a sliding hole on the cylinder (27)
The arm supporting the movement (22) Fig. 1, 2, 3 is fixed on a support cylinder (21) which fixes at its center a bearing and the whole fixed on the plate (4).

 The cylinder (21) and arms (22) follow the whole assembly (27) (23) (24) (14) Fig. 3 the bearing and axis in its movement in the groove (5) to keep it in line.

The groove (5) is mainly designed to turn the pages properly.

 The right part of the groove Fig. 1 is used to slide the page 2 cm back once it is sucked by the suction cup, eg in the same way as we do with a finger when we want to turn a page by hand.

 Then, the bearing (27) engages to follow the path of the groove (5).

 Thus, this bearing (27) continues its course to the end of the groove (5) and stops, leaving the entire location and visual free for any manual intervention.

As for the options (15) Fig. 1.2. for musicians giving concerts in the open air, the way it works
The arm (14) with the suction cup (17) Fig. 1 descend on the page to suck it, learn on a stop (31) of the option (15) a finger (32) which is placed on the sheet to hold it, pivots, the suction cup (17) sucks the page and turns it; starting from the arm (14) moves away from the stop (31) and a spring on the option (15) brings the finger (32) on the page to maintain it.

 In the same way when the arm (14) deposits the page.

 Descending on the stop (33) the finger (34) lifts (pivots), the page falls because it is no longer sucked by the suction cup because the arm (14) is at its end of travel; at this moment the arm (14) starts again the ascent by an impulse in advance ready for another restart and comes to a standstill thus being released from the stop (33) and the finger (34) rests again on the page to maintain it wind thanks to the spring placed on option (15).

 Another bearing (25) Fig. 3 is placed on the plate to fix it at each end of the plate (4) elements used for its operation.

 On one side of the bearing (25), there is fixed a cylinder block (30), a movement rod (19) the other side of the movement rod (19) is fixed an axis and bearing (26).

 On this axis and bearing (26), there is fixed a connecting rod (23), the opposite side of the connecting rod (23) the connecting rod is perforated to place it on the axis which passes through the bearing.

cylinders (27) and (24). The cylinder (24) adjustable according to revised height in turn serves to fix the suction cup support arm (14) to it.

 The other side of the bearing (25) Fig. 3 on the plate (4), a notched pulley (6) is fixed on the axis which crosses the bearing (25) the wedge and the movement rod (19).

 In this same axis next to the toothed pulley (6) is fixed a cylinder movement rod (9).

 The movable cylinder rod head (10) is equipped with a bearing fixed in a cylinder which simultaneously maintains the bearing and the rod of the mobile cylinder (11).

 The cylinder (12) is fixed by a cylinder support (28).

 A toothed belt (7) connects the toothed pulley (6) of the motor (8).

 The 12 V 220 V motor (8) can run on batteries or in a 220 V sector.

 On the jack (12), there is fixed a flexible rubber tube (13) to fix it at the end with a suction cup (17) which sucks the page.

 The device for turning the 220 V electric and battery operated pages of magazines and music scores, includes: a very light case PL 4/4 Fig. 1 which includes all the shapes and bumps of the page turner to protect it, can remain in the case even when it is used; it suffices to open the case, the cover (36) thereof fixed by hinges (37), once opened it turns over below the case following the hinges. Thus open, it is placed on a desk located inside and the page-turner remains free from the case. The lateral top and bottom sides of the case (38) also fitted with hinges (37) can also open, freeing up space at 100 W for turning. Thus the open case we can recover the lectern if necessary, the wire and electrical box, magazines, scores, pencil, eraser or pen if necessary and accessories: screwdriver, beater key of the page turner, etc.

The plates (1) and (2) are made of aluminum or plastic material for the advantage of their rigidity and lightness where the upper plate (2) made of thin metal sheet for the attachment of the magnets (16) which hold the magazine, or two adjustable rectangular metal sheets on the aluminum plate (2) for the magnets (16) which hold the magazines. These plates
(1) and (2) are held together at the corner sides by four cylindrical columns adjustable in height.

 The main cam plate (4) is also made of aluminum or plastic. There is manufactured a grooved slot (5) for the operation of the movement of the arm (14) which turns the page, a hole to incorporate a bearing with a cylinder (21) and its sliding arm (22) and another hole for incorporate a bearing (25) and that is fixed in a cylindrical wedge end and connecting rod, on the other side, a connecting rod pulley for suction cylinder.

 The pulley (6) of the plate (4) is connected by a belt (7) to the pulley (6) of the motor (8) or pulley against pulley operating at 220 V or with batteries.

 The cylinder moves by its axis and central bearing driven by the connecting rod (23) and the sliding of the arm (22) in the cylinder (27).

An axis passes through the bearing, cylinder (27), connecting rod
(23) and cylinder (24). On the cylinder (24) there is fixed the adjustable arm (14) used to hold the suction cup for the suction of the page; the cylinder (24) is made up of two parts used for adjusting the arm (14) higher or lower depending on the thickness of the book, magazine or score. The arm (14) consists of a flexible strip bar or rigid bar depending on the use of the thickness of the book, magazine or score. Three adjustments or choices for the thickness of the book or magazine: cylinder (24) in two parts, the arm (14), flexible strip, cylindrical columns (3).

 The cylinder (30) is a thickness for aligning the connecting rod (19) which, coupled with an axis and a bearing (26) drives the connecting rod (23) and the whole assembly (27) (24) (14) .

 The axis which crosses the bearing (25) on the pulley side (6) drives a connecting rod (9) which in turn drives the head (10) of a rod (11) of the jack (12). This cylinder (12) being held by a support (28) angle with axis.

 The support block (29) adjustable on the arm (14) is designed to hold the suction cup (17) connected to the flexible rubber tube (13) in turn connected to the jack (12).

 When the arm (14) descends to vacuum the page, presses on a stop (31) of the option (15), the finger (32) lifts, the suction cup (17) sucks the page and turns it; starting from the arm (14) is raised, a spring on the option (15) brings back the stop (31) and the finger (32) on the page. The arm (14) having made its full stroke (therefore page turned) presses on the stop (33), the finger (34) is raised and the page is raised, the arm (14) begins to rise again, disengages from the stop (33) and the finger (34) is placed on the page attracted by the spring of the option (15) - the arm (14) is immobilized thus leaving all the visuality and release of the magazine or score.
