BACKGROUND OF THE INVENTION
1. Technical Field
This invention relates to page rotating devices and, more particularly, to a power-operated page rotating device for automatically turning a musicians page during a musical performance.
2. Prior Art
At a recital, and other music performances, it has often been seen that a musician interrupts playing, crouches forward, hurriedly turns the pages of a music book with his hands, and then resumes playing. Alternately, an assistant sitting behind a musician carefully gazes at the music book, and from time to time stands up and turns pages for the musician. Such page turning acts are primitive and troublesome, since no fumbling or mistake is permitted. Numerous inventions have been proposed as better solutions to those problems, but up until now, none are considered good enough in terms of versatility, inconspicuousness, and especially, in reliability.
One prior art example shows a page turning device that is placed on a music stand by a clip. A preformed set of a flat spring mechanism is fixed in an opening which is located in the center of the device. Each spring has a predetermined length; the first spring resting on the page turning device is the shortest. The second spring is longer by a predetermined length. The last spring is the longest. A narrow pocket is located at the bottom of each transparency. Each spring is connected to a transparency. To operate, each transparency is placed behind a page which is to be turned, and with the aid of a clip the transparency and the page are held together.
All the springs are arranged in the unit in the following way: The shortest spring turns the first page; the longest spring turns the last page. The movable unit is connected by a cable to a gear of a toothed gear wheel located in the pedal. Every pedal depression results in a predetermined pull of a cable around the gear, causing the movable unit to move to the right on the device and to release one pressed spring which returns to its initial position, causing a page to be turned. Unfortunately, this device is overly complicated in design and is rather heavy, making the transport thereof difficult. The above-noted example is also limited in the number of sheets that can be held therein by the number of springs that can be incorporated into the device.
Accordingly, a need remains for a power-operated page rotating device in order to overcome the above-noted shortcomings. The present invention satisfies such a need by providing a device that is convenient and easy to use, is portable in nature, is versatile in its uses, and has stress-reducing and performance enhancing qualities. When a musician is required to perform lengthy pieces of music, the page rotating device provides him or her with a convenient, hands-free means of turning the individual pages of sheet music. By simply pressing the control, the performer can turn pages of sheet music without worrying that the sheets might fall from the stand or become rearranged. This eliminates the need for musicians to remove their hands from an instrument in order to turn pages and thus reduces performance anxiety during a show in which page turning is required. The device also eliminates the need to have another individual sitting or standing nearby for the sole purpose of turning pages.
BRIEF SUMMARY OF THE INVENTION
In view of the foregoing background, it is therefore an object of the present invention to provide a power-operated page rotating device. These and other objects, features, and advantages of the invention are provided by a power-operated page turning device for automatically turning a musician's page during a musical performance.
The power-operated page turning device includes a planar rear support plate. An elongated and cylindrical housing is provided that has a first longitudinal length. Such a housing is directly and statically coupled to the support plate. An elongated and rectilinear central shaft has axially opposed top and bottom ends registered along a vertical plane. Such a central shaft has a second longitudinal length and is rotatably seated within the housing. The second longitudinal length is shorter than the first longitudinal length. The central shaft preferably has a threaded outer surface extending along a major portion of the second longitudinal length.
A plurality of page-holding sections are operably coupled to the central shaft. Each of the page-holding sections has an inner linear edge disposed adjacent to the central shaft and extends parallel to the central shaft. Such inner edges of the page-holding sections are seated within the housing. Each of the page-holding sections includes a plurality of non-linear wire ribs attached thereto for advantageously and effectively preventing the page-holding sections from undesirably flexing during rotating movement. Such wire ribs diagonally span along a major length of the page-holding sections. Each of the page-holding sections preferably includes a T-shaped lever registered within the housing and medially located between the interior and exterior walls of the housing. Such a T-shaped lever is rigidly connected directly to a corresponding one of the inner edges in such a manner that the arm engages the T-shaped lever and thereby causes the page-holding section to articulate about the central shaft.
A mechanism is included for selectively rotating the page-holding sections about the central shaft such that the inner edges of the page-holding sections remain equidistantly spaced from the central shaft and travel substantially 180 degrees along an arcuate path. Such a rotating mechanism rotates the page-holding sections in clockwise and counter clockwise directions when the central shaft is rotated in clockwise and counter clockwise directions respectively. The rotating mechanism preferably includes a finger that has a body directly engaged about the central shaft. Such a body is linearly displaced along the central shaft and travels along the second longitudinal length when the central shaft rotates. The finger further has an arm monolithically formed with the body. Such an arm extends laterally and horizontally away from the central shaft and terminates within the housing.
A motor is operably coupled directly to the top end of the central shaft. Such a motor effectively drives the shaft. A controller is electrically mated to the motor. Such a controller is disposed to an exterior of the housing and is tethered to the motor such that a user can conveniently easily operate the motor while playing an instrument. The housing includes an exterior wall provided with a plurality of equidistantly spaced curvilinear slots formed therein. The arm engages the page-holding sections and thereby effectively causes the inner edges to independently articulate about the curvilinear slots and rotate along the arcuate path respectively. The housing may further include an interior wall that is equidistantly spaced about the central shaft and the outer wall respectively. Such an interior wall is provided with a continuous helical groove traveling along the second longitudinal length. The arm is guided along the helical groove when the central shaft is rotated.
The device may further include a telescopic support stand that has a male portion directly coupled to a rear surface of the support plate. Such a support stand further has a female portion provided with a plurality of equidistantly spaced legs such that the support plate can be maintained at a substantially stable position above ground level.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.

DETAILED DESCRIPTION OF THE INVENTION
The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which a preferred embodiment of the invention is shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiment set forth herein. Rather, this embodiment is provided so that this application will be thorough and complete, and will fully convey the true scope of the invention to those skilled in the art. Like numbers refer to like elements throughout the figures.
The device of this invention is referred to generally in FIGS. 1-5 by the reference numeral 10 and is intended to provide a power-operated page rotating device. It should be understood that the device 10 may be used to rotate many different types of pages and/or sheets and should not be limited in use to only rotating a musician's sheet music.
Referring initially to FIGS. 1, 2, 3, 4 and 5, the device 10 includes a planar rear support plate 20. An elongated and cylindrical housing 21 is provided that has a first longitudinal length. Such a housing 21 is directly and statically coupled, without the use of intervening elements, to the support plate 20, as is best shown in FIG. 4. An elongated and rectilinear central shaft 22 has axially opposed top 23A and bottom 23B ends registered along a vertical plane. Such a central shaft 22 has a second longitudinal length and is rotatably seated within the housing 21. The second longitudinal length is shorter than the first longitudinal length, which is crucial for allowing central shaft 22 to become completely disposed within the housing 21. The central shaft 22 has a threaded outer surface 24 extending along a major portion of the second longitudinal length.
Referring to FIGS. 1 through 4, a plurality of page-holding sections 30 are operably coupled to the central shaft 22. Each of the page-holding sections 30 has an inner linear edge 31 disposed adjacent to the central shaft 22 and extending parallel to the central shaft 22. Such inner edges 31 of the page-holding sections 30 are seated within the housing 21, as is illustrated in FIGS. 3 and 4. Each of the page-holding sections 30 includes a plurality of non-linear wire ribs 32 attached thereto that are essential for advantageously and effectively preventing the page-holding sections 30 from undesirably flexing during rotating movement. Such wire ribs 32 diagonally span along a major length of the page-holding sections 30. Each of the page-holding sections 30 includes a T-shaped lever 33 registered within the housing 21 and medially located between the interior 25A and exterior 25B walls of the housing 21. Such a T-shaped lever 33 is rigidly connected directly, without the use of intervening elements, to a corresponding one of the inner edges 31 in such a manner that the arm 43 (described herein below) engages the T-shaped lever 33 and thereby effectively causes the page-holding section 30 to articulate about the central shaft 22.
Referring to FIGS. 3 and 4, a mechanism 40 is included for selectively rotating the page-holding sections 30 about the central shaft 22 such that the inner edges 31 of the page-holding sections 30 remain equidistantly spaced from the central shaft 22 and travel substantially 180 degrees along an arcuate path. Such a rotating mechanism 40 rotates the page-holding sections 40 in clockwise and counter clockwise directions when the central shaft 22 is rotated in clockwise and counter clockwise directions respectively. The rotating mechanism 40 includes a finger 41 that has a body 42 directly engaged, without the use of intervening elements, about the central shaft 22. Such a body 42 is linearly displaced along the central shaft 22 and travels along the second longitudinal length when the central shaft 22 rotates. The finger 41 further has an arm 43 monolithically formed with the body 42. Such an arm 43 extends laterally and horizontally away from the central shaft 22 and terminates within the housing 21.
Referring to FIGS. 1 through 5, a motor 44 is operably coupled directly, without the use of intervening elements, to the top end 23A of the central shaft 22. Such a motor 44 effectively drives the central shaft 22. A controller 45 is electrically mated to the motor 44. Such a controller 45 is disposed to an exterior of the housing 21 and is tethered to the motor 44, which is crucial such that a user can conveniently easily operate the motor 44 while playing an instrument. The housing 21 includes an exterior wall 25B provided with a plurality of equidistantly spaced curvilinear slots 26 formed therein. The arm 43 engages the page-holding sections 30 and thereby effectively causes the inner edges 31 to independently articulate about the curvilinear slots 26 and rotate along the arcuate path respectively. The housing 21 further includes an interior wall 25A that is equidistantly spaced about the central shaft 22 and the outer wall 25B respectively. Such an interior wall 25A is provided with a continuous helical groove 27 traveling along the second longitudinal length. The arm 43 is guided along the helical groove 27 when the central shaft 22 is rotated.
Referring to FIGS. 2 and 5, the device 10 further includes a telescopic support stand 50 that has a male portion 51 directly coupled, without the use of intervening elements, to a rear surface 28 of the support plate 20. Such a support stand 50 further has a female portion 52 provided with a plurality of equidistantly spaced legs 53 that are critical such that the support plate 20 can be maintained at a substantially stable position above ground level. The telescoping nature of support stand 50 is vital for allowing a musician to support their sheet music at a convenient and comfortable height, whether they are playing at a seated or a standing position.
In use, when a musician has multiple pages of sheet music for a particular selection or performance, they first place each sheet within a respective page-holding section 30. Once the pages are correctly arranged, the musician can place the support plate 20 on the support stand 50. Of course, the support plate 20 can be placed on the music desk area of a piano, keyboard, etc., as is obvious to a person of ordinary skill in the art. The user then simply activates the device 10, places the controller 45 in a preferred location, places their instrument or hands at the appropriate playing position, and begins their performance. Once the musician reaches the end of the first page they press the controller 45, causing the motor 44 to move the arm 43, and subsequently the page section 30. This effectively and conveniently reveals the next two pages of sheet music, and allows the musician's hands to remain on their instrument. This, in turn, results in a smoother performance by the musician, and provides a stress-free method for rotating their pages of sheet music.
While the invention has been described with respect to a certain specific embodiment, it will be appreciated that many modifications and changes may be made by those skilled in the art without departing from the spirit of the invention. It is intended, therefore, by the appended claims to cover all such modifications and changes as fall within the true spirit and scope of the invention.
In particular, with respect to the above description, it is to be realized that the optimum dimensional relationships for the parts of the present invention may include variations in size, materials, shape, form, function and manner of operation. The assembly and use of the present invention are deemed readily apparent and obvious to one skilled in the art.
