Description

The present invention stores a folding screen picture, an old document including an old map, a paper-based art object such as a hanging scroll, and a sheet-like object such as a flexible display panel such as an organic EL without creases. It also relates to a hinge structure that can be easily expanded from a stored state to a flat state.

Since the artistic value of old documents, hanging scrolls, and other works of art is impaired by the formation of creases, it is necessary to store them without creases. Further, since the display characteristics of a flexible display panel such as an organic EL deteriorate when creases are formed, it is necessary to prevent creases from occurring when folding. In addition, these articles are preferably developed in a flat state during viewing and data reading. Therefore, the storage member for storing these articles is required to have a function of being folded so as not to be creases and being easily expanded into a flat state.

Patent Document 1 discloses a conventional structure that seems to have the above functions. This Patent Document 1 is applied to a flexible display panel as an article.
This conventional structure has a first housing in which an internal space is formed, and a second housing and a third housing that are foldably connected to both ends of the first housing, and a flexible display panel is provided. It is fixed to the second housing and the third housing. Then, in a state where the second housing and the third housing are not bent, the folded portion of the flexible display panel is stored in the space of the first housing, and the second housing and the third housing are bent in a direction in which they are separated from each other. In the open state, the flexible display panel becomes flat, and the first housing functions as legs protruding from the planes of the second housing and the third housing, connecting the second housing and the third housing. The second housing and the third housing are fixed by the holding member, and the folded portion of the flexible display panel is supported.

Japanese Unexamined Patent Publication No. 2016-15618

In the conventional structure, since it is necessary to form a space for storing the folded portion of the flexible display panel in the first housing, the first housing becomes bulky and the entire structure becomes large. Further, when the second housing and the third housing are bent to be in a horizontal state, the first housing between them serves as a leg to form a recess in the first housing portion, so that the second housing is formed. It is not possible to maintain a smooth flat state of the flexible display panel mounted on the body and the third housing.
In order to maintain the flat state of the flexible display panel, it is necessary to arrange the holding member between the second housing and the third housing. Therefore, there is an additional operation of arranging and removing the holding member when the second housing and the third housing change to the horizontal state and the closed state. Therefore, there is a problem that the operation is complicated and the operability is poor.
Further, in the conventional structure, even if it can be applied to a flexible display panel, there is a problem that it is difficult to apply it to paper materials such as folding screens and old documents. This is because paper materials are thinner than flexible display panels, have a fragile structure, and have low strength, so wrinkles and creases are likely to occur when performing complicated operations such as those used in conventional structures.

The present invention has been made in consideration of the above-mentioned problems of the conventional structure, and it is easy to operate in the horizontal and closed states without increasing the size, and the operability is good, and the creases and wrinkles of the paper material are formed.

As shown in FIG. 4, each main body member 2 has a thick plate portion 11 and a thin plate portion 12 having a plate thickness (t1> t2) thinner than the thick plate portion 11, as shown in FIGS. 1 to 3. The thin plate portions 12 are arranged side by side so as to face each other, and the hanging members 3 are superposed on the pair of main body members 2 in this side by side state. The hanging member 3 is hung so that the pair of main body members 2 can be deployed and closed. The closing operation is performed by rotating the pair of main body members 2 in the arrow α direction (see FIGS. 1 and 2), and the unfolding operation is performed by rotating the pair of main body members 2 in the anti-α direction.
A frame frame 14 thickened in a stepped manner is formed on the outer peripheral portion of the front surface of each main body member 2 (see FIG. 1), and a rib portion for increasing strength is formed on the back surface of the main body member 2. 15 is formed (see FIG. 2). Further, the thick plate portion 11 is formed so as to be longer than the thin plate portion 12. Here, the thin plate portion 12 is stepped lower than the thick plate portion 11, and a support claw 6 described later is attached to the thin plate portion 12.

The hanging member 3 is hung on a pair of main body members 2. In this embodiment, the cover 7 corresponds to the hanging member 3, and the hanging member 3 and the cover 7 are the same members. The cover 7 as the hanging member 3 is superposed on the pair of main body members 2 so as to cover the entire one side (opposite side surface 32 described later) of the pair of main body members 2.

As described above, the cover 7 is superposed on the pair of main body members 2 so as to cover the entire surface 31 on the opposite side and the surface 32 on the opposite side of the pair of main body members 2. The overlapped cover 7 is fastened to the opposite surface 32 of the main body member 2. Fastening can be done by screws, sewing, adhesion, or the like. As the cover 7, a flexible sheet having a thin thickness is used, and for example, a resin sheet, a leather sheet, a cloth sheet, a paper sheet, or other materials can be used.

In FIGS. 1 and 2, reference numeral 30 is a bridging block. The bridging block 30 is formed of a flexible elastic member such as rubber having a U-shaped cross section, and auxiliaryly connects both ends of the pair of main body members in the width direction (Y direction). A bridging rod 13 extending in the direction of the mating main body member 2 is fixed to both ends of the pair of main body members 2 in the width direction (Y direction) with respect to the bridging block 30, and the bridging block 30 is fixed to the bridging block 30. The pair of main body members 2 are connected by elastically grasping the bridging rod 13. As a result, the connected state of the main body members 2 is ensured during the closing and unfolding operations of the pair of main body members 2.

The support claws 6 are attached to each of the pair of main body members 2. As shown in FIGS. 3 and 7, the support claw 6 is formed by a fixing portion 17 on the base end side and a claw portion 18 on the tip end side, and the fixing portion 17 is screwed 16 to the main body member 2 (see FIG. 9). Is fixed by. The entire support claw 6 extends from the fixing portion 17 in the direction of the main body member 2 on the mating side, and the extending tip side serves as the claw portion 18. As shown in FIGS. 1 to 3, the claw portion 18 has a shape curved toward the front side, and the tip portion thereof has a free end.

A plurality of support claws 6 (three in the illustrated example) are arranged along the width direction of each main body member 2. In this case, the support claw 6 of one main body member 2 and the support claw 6 of the other main body member 2 are arranged so as to be displaced in the width direction (Y direction). In the closed state of the main body member 2 shown in FIG. 7, the support claw 6 is in a retracted state in which the claw portion 18 at the tip portion is separated from the wing member 4 and the center member 5, but the main body member 2 shown in FIG. In the unfolded state, the claw portion 18 at the tip portion operates so as to support the wing member 4 (or the center member 5). At this time, the claw portion 18 at the tip portion abuts on the wing member 4 (or center member 5) from the back side as the pair of main body members 2 unfolds, and supports the wing member 4 and the center member 5 from the back side. Such support is provided so that the wing member 4 has the same height as the mounting surface 10 (see FIGS. 8 and 9) formed by the thick plate portions 11 of the pair of main body members 2, and the claw portion 18 has the same height. The curvature is set so that such contact and support is possible.

FIG. 5 shows a pair of wing members 4 and a center member 5, and the center member 5 is connected to the wing member 4 in a state of being located between the pair of wing members 4. Each wing member 4 has a flat plate-shaped wing main body 20 extending in the width direction (Y direction), and a connecting bracket portion 21 fixed to the back side of each wing main body 20. A plurality (two in the illustrated example) of the connecting bracket portions 21 are fixed to one wing member 4 along the width direction (Y direction).

Each connecting bracket portion 21 is formed with a pair of connecting arm portions 22 extending in the direction of the center member 5 and a pair of pin supporting portions 23 extending on the side opposite to the connecting arm portion 22.
A connecting shaft 24 extending in the width direction (Y direction) is inserted through the pair of connecting arm portions 22. The connecting shaft 24 inserts the wing member 4 and the center member 5 arranged between the wing members 4, and the center member 5 is connected to the wing member 4 by inserting the connecting shaft 24. As a result, the center member 5 and the wing member 4 operate integrally.
A guide pin 25, which is one of the constituent members of the engaging member 8 described later, is attached to the pair of pin support portions 23 in the connecting bracket portion 21. The guide pin 25 is fixed to the pin support portion 23 so as to project outward with respect to each of the pair of pin support portions 23. As a result, the guide pin 25 is provided on the wing member 4 via the connecting bracket portion 21.
In FIG. 5, reference numeral 26 is a holding block, which is screwed to the center member 5. The pressing block 26 presses the center member 5 and the wing member 4, and thereby functions to hold the connected state of the wing member 4 and the center member 5 connected by the connecting shaft 24.

In this embodiment, the engaging member 8 is formed by the guide pin 25 which is one constituent member and the guide groove 27 which is the other constituent member (see FIGS. 6 to 8). In FIGS. 1 and 2, reference numeral 28 is a guide block in which the guide groove 27 is formed. The guide block 28 is fixed to the thin plate portion 12 of the main body member 2 by screws. Therefore, the guide groove 27 is provided in the main body member 2 with respect to the guide pin 25 provided in the wing member 4.
The guide block 28 is fixed to the main body member 2 so as to be located on both sides of each connecting bracket portion 21 fixed to the wing member 4 (so as to be positioned so as to sandwich the connecting bracket portion 21). A guide pin 25 protruding from the pin support portion 23 of the connecting bracket portion 21 is inserted into the guide groove 27 of each guide block 28 so as to be relatively slidable. By inserting the guide pin 25 into the guide groove 27 in this way, the engaging member 8 is formed, and the wing member 4 is connected to the main body member 2 via the engaging member 8.

FIG. 6 is a cross-sectional view of the closed state of the pair of main body members 2 cut at the guide groove 27 portion, FIG. 7 is a cross-sectional view of the closed state of the pair of main body members 2 cut at the support claw 6 portion, and FIG. The unfolded state of the main body member 2 is cut so as to correspond to FIG. 6, and FIG. 9 is a cross-sectional view obtained by cutting the unfolded state of the pair of main body members 2 so as to correspond to FIG. As shown in these figures, in the closed state of the pair of main body members 2, the other faces of the pair of main body members 2 face each other, and this is referred to as the facing side faces 31. Further, the surface opposite to the surface 31 on the facing side (which is the lower surface in FIGS. 8 and 9) is referred to as the surface 32 on the opposite side. The cover 7 is superposed on the surface 32 on the opposite side.
As shown in FIGS. 6 and 8, the guide groove 27 on the main body member 2 (guide block 28) side constituting one of the engaging members 8 communicates with the oblique slide groove portion 27a and one end side of the slide groove portion 27a. It is formed by a positioning groove portion 27b.

In the closed state of the pair of main body members 2, the guide pin 25 on the wing member 4 (connecting bracket portion 21) side is located at the end of the slide groove portion 27a (the end opposite to the positioning groove portion 27b) as shown in FIG. doing. When the main body member 2 is rotated in the deployment direction in this state, the support claws 6 move integrally, and the claw portion 18 at the tip abuts on the wing member 4 to press the wing member 4. As a result, the wing member 4 moves in the pressing direction, and the guide pin 25 slides in the slide groove portion 27a in the direction of the positioning groove portion 27b with this movement. In the horizontal state in which the pair of main body members 2 are opened 180 degrees, the guide pin 25 enters the positioning groove portion 27b. As a result, the movement of the wing member 4 in the pressing direction is stopped, and the horizontal unfolded state of the main body member 2 is maintained. The positioning groove portion 27b is formed in the guide groove 27 so as to maintain such a horizontally expanded state. The support claw 6 may press the center member 5 instead of the wing member 4. Since the center member 5 and the wing member 4 are connected by the connecting shaft 24, the wing member 4 moves in the same manner by pressing the center member 5.
Here, in the deployed state of the pair of main body members 2, the surface 31 on the facing side of the pair of main body members 2 has the same height to form the mounting surface 10, but the engaging member 8 is the pair of main bodies. The wing member 4 is set to have the same height as the mounting surface 10 in the unfolded state of the member 2. Therefore, the length and inclination of the guide groove 27 constituting the engaging member 8 are set in this way.

Next, the operation of this embodiment will be described.
The sheet-shaped member 100 held by the hinge structure 1 of this embodiment is arranged so as to cover the back surface side of the pair of main body members 2, and both ends in the length direction (X direction) are on the outer peripheral portion of the main body member 2. It is locked. As the locking means, screws, clips, double-sided adhesive tape, or other appropriate means can be used. When the sheet-shaped member 100 is a flexible display panel such as an organic EL, information such as images and characters is displayed on the screen, and touch keys such as a numeric keypad are displayed on the screen. In addition, by tapping the touch key, it is possible to connect to the Internet network and perform e-mail communication. As shown in FIG. 1, the sheet-shaped member 100 is provided so as to cover the entire surface of the pair of main body members 2. In the sheet-shaped member 100, both end portions or peripheral portions in the length direction (X direction) are connected to the outer peripheral portion of the main body member 2, but the intermediate portion is mounted on the main body member 2 without being connected to the main body member 2. It is in a placed state. The sheet-shaped member 100 is connected to the main body member 2 by screwing, clipping, or other appropriate connecting means. By connecting both ends or the periphery of the sheet-shaped member 100 in the length direction to the main body member 2, the sheet-shaped member 100 is folded following the closing operation of the main body member 2, while the main body member 2 is expanded. It follows and is developed in a plane.

In a state where the pair of main body members 2 are closed, the main body members 2 face each other with the facing surfaces 31 as shown in FIGS. 6 and 7. At this time, the cover 7 is overlapped with the surface 32 on the opposite side, and the accommodating space 9 is formed by the cover 7 (hanging member 3). By forming the accommodation space 9 in this way, the slack portion (extra length portion) 110 of the sheet-like member 100 can be curved in the accommodation space 9. The curved shape prevents creases and wrinkles from occurring even if the sheet-like member 100 is a fragile and low-strength paper material. Further, when the sheet-shaped member 100 is a flexible display panel, no creases are generated, so that the display of information such as characters and figures displayed by the panel is not difficult to see.

8 and 9 show a state in which the pair of main body members 2 are unfolded. A cover 7 constituting the hanging member 3 is hung on the pair of main body members 2, and the pair of main body members 2 are connected by this hanging. As a result, the pair of main body members 2 can rotate from the closed state to the expanded state. In the unfolded state of the main body member 2, the facing surfaces 31 of the pair of main body members 2 have the same height, so that the facing surfaces 31 form the mounting surfaces 10 having the same height. Further, the engaging member 8 composed of the guide pin 25 and the guide groove 27 moves the wing member 4 so as to have the same height as the mounting surface 10 of the main body member 4. Since the center member 5 is connected to the wing member 4 by the connecting shaft 24, it moves to the same height as the wing member 4. That is, the wing member 4 and the center member 5 move between the surfaces 31 on the opposite side of the main body member 2 to be the mounting surface 10, and the same height as the mounting surface 10 is continuous. As a result, the sheet-shaped member 100 is supported and deployed so as to be flush with the mounting surface 10, the wing member 4, and the center member 5. Therefore, the content displayed by the sheet-shaped member 100 can be easily and surely read and observed.

In such an embodiment, the accommodating space 9 is formed in the cover 7 (hanging member 3) in the closed state of the pair of main body members 2, and the same height is applied to the facing surface 31 in the unfolded state of the pair of main body members 2. Since the mounting surface 10 is formed, the sheet-like member 100 does not become large when it is accommodated or unfolded. In addition, it is easy to operate in the horizontal and closed states, and the operability is good. Further, even when the sheet-shaped member 100 is a paper material, it is possible to prevent the occurrence of creases and wrinkles on the paper material.

In this embodiment, in the deployed state of the pair of main body members 2, the claw portion 18 at the tip of the support claw 6 is surely supported so that the wing member 4 is at the same height as the mounting surface 10 of the main body member 2. As a result, the gap between the facing surfaces 31 of the pair of main body members 2 is filled with the wing members 4 having the same height, and the gap disappears. Therefore, it is possible to support a good unfolded state of the sheet-shaped member 100, the holding member described in Patent Document 1 becomes unnecessary, the operation of arranging and removing the holding member becomes unnecessary, and the operability is further improved. Become.

Further, in the deployed state of the pair of main body members 2, the support claws 6 support the wing member 4 so as to have the same height as the mounting surface 10 formed by the pair of main body members 2. Therefore, it is possible to support a good unfolded state of the sheet-shaped member 100, and the display of the sheet-shaped member 100 can be read well. Further, by supporting the wing member 4 in this way, the sheet-like member 100 does not dent even if the sheet-like member 100 on the wing member 4 is hit or pressed. Therefore, when the sheet-shaped member 100 is a flexible display panel, the influence of tapping or pressing on the panel is eliminated, and information can be input to the panel satisfactorily.

Here, the cover 7 as the hanging member 3 may be slidable relative to the surface 32 on the opposite side. In such a structure, when the pair of main body members 2 rotate to perform the closing operation and the deploying operation, the cover 7 slides following this operation. As a result, the cover 7 is not loosened, and the opening / closing operation of the pair of main body members 2 is not hindered.
In this embodiment, a plurality (two) of slide slits 33 are formed in each of the pair of main body members 2 in order to secure the relative slide of the cover 7 (see FIGS. 1 to 3). Each of the slide slits 33 extends along the length direction (X direction). On the other hand, although not shown, the cover 7 is provided with a slide boss that is slidably inserted into the slide slit 33. As a result, the cover 7 is attached to the pair of main body members 2 in a superposed state, and the slide boss slides the slide slit 33 as the pair of main body members 2 rotate to close and deploy. As a result, the cover 7 slides following the rotation of the main body member 2.
The length of the slide slit 33 is set so that the slide boss reaches the end when the pair of main body members 2 are closed and unfolded. Specifically, when the pair of main body members 2 shown in FIGS. 6 and 7 are closed, the slide boss reaches the inner end of the slide slit 33, while the pair of main body members 2 shown in FIGS. 8 and 9 are used. At the time of deployment, the length of the slide slit 33 is set so that the slide boss reaches the outer end of the slide slit 33. By setting in this way, the closed state and the unfolded state of the pair of main body members 2 are fixed, and the closed state of FIGS. 6 and 7 and the unfolded state of FIGS. 8 and 9 can be maintained.
Here, the cover 7 may be formed so that a plurality of (at least two) slide bosses correspond to one slide slit 33. In the case of two slide bosses, these slide bosses are provided at intervals, and in the closing operation of the pair of main body members 2, one slide boss reaches the inner end of the slide slit 33, and the pair In the unfolding operation of the main body member 2, the other slide boss may reach the outer end of the slide slit 33.
The above structure can be applied to other embodiments after the second embodiment.
