Abstract

The utility model is a page turning device. A viscous contact element is arranged at a page turning bar fixed a support stand for book placing and a turned page. Since the viscous contact element is made of a directional viscous material, so that the element can stick to a page firmly at the initial stage of page turning; and during the process of page turning, due to the position of a page turning rod shaft fixed at the support stand being deviated from the central line of the turned book at the support stand, the contact elements produce a displacement in between towards the direction of less viscosity so as to lose viscosity entirely, with the time when the page turning travel is ended to make the page turning bar to deviate from a page. This simple structure efficiently solves a key difficult point by using mechanism instead of for page turning by hand. The device can stick to a page firmly at the initial stage of page turning and lose the viscosity during ending stage so as to enable the page-turning bar to deviate from the page. The device can be used for music books, magazines, and books instead of page turning by hand.

Description

A kind of leaf turner

Affiliated technical field

The utility model is a kind of leaf turner that is used to read music score, magazine, book.

Background technology

Usually, when reading music score or book reading matter, people use the handspring page or leaf.This is for Instrumentalist or very inconvenience of some handicapped persons.Replace the key point (also can be described as a main difficult point) with the handspring page or leaf, be that the initialization phase that the page turning apparatus contacted and started the page will pick up the page firmly, and will break away from the page in the ending stage of page turning stroke, both are just in time opposite.China utility model patent CN86203463U discloses a kind of leaf turner, its weak point is, the magnetic sticking device of the contact page can magnetize to the metal object of predetermined fixed on the page, cause the metal object magnetic adhesion of prevpage and the next page, influence page turning, its another weak point is, the ending stage of page turning stroke is to make the magnetic sticking device of the contact page break away from the page, have to form complicated clamp mechanism and clamp the page that has overturn, increased the complexity of leaf turner greatly with more than 10 parts nearly.China utility model patent notification number CN2033743U discloses a kind of leaf turner, and its weak point is that the rubber friction head of the contact page can not start the page reliably on the page turning pivoted arm, is difficult to adapt to the different soft and hard degree of page paper.China utility model patent notification number CN2033340U discloses a kind of leaf turner, and its weak point is to start the page respectively and break away from the page with two complex structure assemblies.

Summary of the invention

The purpose of this utility model is to provide a kind of structure ingenious and simple leaf turner.The purpose of this utility model is achieved in that it is made up of a page turning bar that sways and the carriage of shelving music score or book.The axle that the page turning bar rotates is fixed on and departs from the position of being stirred the book center line on the carriage.The page turning bar all has contact element with the page that is stirred book.This contact element is made of the material that directionality changes viscosity.In the page turning stroke, the fixing axle center of book center line of departing from of page turning bar combines with the directionality variation viscosity of contact element, weakens automatically in the ending stage of page turning stroke viscosity, breaks away from the page.

Characteristics by above introduction, can find out that the utility model utilizes the fixing position of page turning bar axle, ingenious combination with contact element viscosity directionality, simply and effectively solved a crucial difficult point of apparatus replacement handspring page or leaf: will firmly cling the page at the initialization phase that starts the page, the ending stage at the page turning stroke will deduct viscosity, so that the page turning bar breaks away from the page.Both are just in time opposite.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the perspective view of an embodiment of the utility model;

Fig. 2 is the actuating length schematic diagram of an embodiment of the utility model.

(1) shelves the carriage of music score or book among the figure, and (2) stir the page turning bar of the page, and (3) music score or book are shelved on the center line on the carriage, and (4) are fixed on the page turning bar axle on the carriage, the contact element on (5) page turning bar, the contact element on (6) page.

The specific embodiment

In the direction of taking back of the center line (3) of the shelf (1) of placing music score or book, fixed page turning bar axle (4).On the page turning bar fixed-site of (5) viscosity contact element that can change with direction.This contact element can adopt known any viscosity to constitute with the material that direction changes, for example, a kind of velcro materials similar, after the contact element of pasting on it and the page (6) is pressed close to, toward pressing close to opposite direction maximum viscosity is arranged, therefore can cling the page on the page turning bar firmly; And stagger toward the 90 degree directions of pressing close to direction are laterally mobile mutually, minimum viscosity is just arranged, be easy to both are separated.

When the page turning bar rotates, because the reason of page turning bar axle (4) disalignment (3), when clinging the contact element of pasting on the page (6), also laterally staggers gradually the contact element of page turning bar (5) past, surpass half up to page turning bar rotational travel, (5) that are the page turning bar have crossed center line (3) one segment distances, just stagger fully, page nature breaks away from the page turning bar, has finished the page turning action.The page turning bar, pastes with contact element (6) on the next page to the right with regard to self-return, waits for that next time the page turning bar rotates and continues page turning.

The page turning bar of present embodiment is arranged on the top of shelf, in like manner also can be identical and be arranged on the bottom of shelf symmetrically, even respectively be provided with one in the upper and lower portion of shelf.Because this is apparent, just repeat no more.Fixed position with the utility model page turning bar moves on to the right from the left side of departing from the book center line simply, also can realize page turning from left to right.Drive the device that page turning bar of the present utility model sways and gets back to initial position automatically, can adopt any of known technology.

The utility model not only can be used on music easel, also may be used on other many occasions that inconvenience is read the book page with handspring.

Claims

1. leaf turner, by the carriage of shelving book (1) be fixed on the carriage and can form around the page turning bar (2) that axle (4) rotates, the axle (4) that it is characterized in that the page turning bar of this device is fixed on the center line (3) that is stirred book on the position deviation carriage on the carriage, this page turning bar is stirred with quilt all contact element (5) and (6) on the page, this contact element is made of the material that directionality changes viscosity.
