Description

DEVICE FOR TURNING OVER THE PAGE OF A SCORE OR THE LIKE BACKGROUND OF THE INVENTION It is found that the commonly used music stand is designed to support a score only- and cannot be used to turn the page of a score thereby causing very much inconvenience to the performer.

It is, therefore, an object of the present invention to provide a device which mar automatically- turn over the page of a score or the like.

SUMMARY OF THE INVENTION This invention reiates to a device especially used for turning over the page of a score.

It is the primary object of the present invention to provide a device which may automaticallv turn over the page of a score simply by pressing an actuating switch.

It is another object of the present invention to provide a device which is specificalls helpful to a performer.

It is still another object of the present invention to provide a device which is also subservient to the typist as well as the disabled.

Other objects and merits and a fuller understanding of the present invention will be obtained b those having ordinary skill in the art when the following detailed description is read in conjunction with the accompanying drawings wherein like numerals refer to like or similar parts and in which: BRIEF DESCRIPTION OF THE DRAWINGS FIG. I is a perspective view of a device for turning over the pages of a score according to the present invention; FIG. 2 is an exploded view of the driving box of the device; FIGS. 3-5 show the stroke of the diving gear; and FIG.6 is an embodiment of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED E'IBODIXIENT With reference to the drawings and in particular to FIG.1 thereof, the device for turning the pages of a score mainly comprises a platform 1, a turning rod 2, a cohering arm 3, a driving box 4 and an actuating switch The platform 1 is used to support a score or the like.

The driving bos Y is disposed at the front portion of the platform 1. The turning rod 2 is driven by the driving box 4 to oscillate horizontally and its length is adjustable. The cohering arm 3 is mounted on the driving box 4 and has at its middle portion a gear 32 for engaging the driving box 4. At each end of the turning rod 2, there is a branch arm 33 which extends over the platform 1. The branch arm 33 is telescopic and provided with an adhesive pad. for cohering the page of a score.

The actuating switch 5 is designed to control the driving box 4 and has two buttons 51 and 52 respectively for controlling the positive and reverse rotation of the motor 41. Between the two buttons 51 and 52 there is a pedal 53 which can control the buttons 51 and 52.

FIG. 2 is an exploded view of the driving box 4. As illustrated the driving box mainly comprises a reversible motor 41, a set of aears 42, a driving gear 43 and two driven plates 44 and 45. The reversible motor 41 is controlled by the actuating switch 5. The output axle of the motor 41 is engaged with a worm 421 which will transmit the power of the motor 41 to the driving gear 3 via the set of gears 42. The upper driven plate 44 is disposed above the driving gear 43 and has at its bottom a pin received in the groove 434. The front edge of the driven plate 4f is provided with threads 442 engageable with the pinion 22 on the branch shaft 21 of the turning rod 2. The rear end of the driven plate 44 is pivoted on the driving box 4 bp a shaft 443.The lower driven plate 45 is mounted under the driving gear 43 and has at its top a pin engaging with the groove 432 of the driving gear 43. The driven plate 4D is provided with a threaded sector 4D2 engageable with the gear set 31 of the turning rod 2. Hence, when the driving gear 43 is driven b a motor 11 and the gear set 42, the turning rod 2 and the cohering arm 3 will move horizontally and vertically respectively through the grooves 431 and 432 and the pins 441 and 451.

On the circumference of the driving gear 43 there is a conductin loop 433 which has a 10-degree notch. Beside the conducting loop 433 there is a spring electrode 435 in contact therewith. The spring electrode 43D is connected to the control circuit of the motor 41. When the actuating switch 5 is turned on to start the motor 41, the driving gear 43 will rotate (meanwhile, the spring electrode 435 is in contact with the conducting wire 433). As the driving gear 43 is rotated to the notch 434, the spring electrode 435 will be separated from the conducting wire 433 therefore eliminating the power to the driving gear 43. However, the driving gear 43 will still travel a small distance due to its inertia.

Thus, when the driving gear 43 completely stops, the spring electrode 435 will be in contact with the conducting sire 433 and wait for the turning of the actuating switch 5. By means of these mecnanisms, the operator may press the actuating switch S once to cause the driving gear 43 to rotate one revolution thereby turning rover one page.

The cycle of the driving gear 43 to actuate the turning rod 2 and the cohering arm 3 may be roughly divided into six strokes.

The strokes for turning the page to the left are as follows: DRIVING GEAR STROKE 0 -10 10 -95 95 -180 180 -265 265 -350 350 -360 TURNING ROD P. R. P.R. M.L. P.L.

R. : MOVING TO RIGHT LT : LIFT FIGS. 3-5 show the present invention turns a page to the left. In FIG. 3, the driving gear 13 is positioned between 00 - 100 and the turning rod is fixed at the right side and the cohering arm 3 is fixed at the bottom, When the driving gear 43 is positioned between 100 - 950 the cohering arm 3 will gradually lift thereby moving a page upwards. As the driving gear 43 moves between 950 1800 , the turning rod 2 will first move to the left and so the turning rod 2 will turn the page attached to the cohering arm 3 to the left (see FIG. 4). FIG. 5 shows the driving gear 43 between 3500 - 3600, i.e. the restoring state.

Regarding the action of turning to the right, it is mainly featured between 950 - 2650 of the driving gear 43 where the cohering arm 3 lifts and the turning rod 2 moves to the right. The motion is similar to that for turning the page to the left and so there is no need to describe again.

It should be noted, however, that the cohering arm 3 is contractible and so it can adapt to scores or books of various thickness. The adhesive tape 34 may be a dualsurface tape and can be replaced when the adherin force thereof is insufficient.

Although the present invention has been described with a certain degree of particularity, it is understood that the present disclosure is made by way of example only and that numerous changes in the detail of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
