Description

  The present invention relates to a hinge device provided at a pivotally mounted portion of an electronic device such as a mobile phone and a mobile, and an electronic device using the hinge device.

  For example, a conventional foldable mobile phone is provided with an operation unit on which the numeric keys and function keys are arranged on the upper surface side of the lower main unit, and a liquid crystal panel on which a predetermined display is made by the key operation of the operation unit. The display part is provided on the lower surface side (polymerization side) of the upper overlapping part (lid part), the main body part and the overlapping part are connected via a hinge device, and the main body part and the overlapping part are folded in half. From the folded closed state where the operation part is concealed by the superposition part, the overlapping part is swung up and down by the hinge device and reversed approximately, so that the operation part and the display part can be switched to the open state. Yes.

  In addition, in the conventional electronic device that covers the operation part of the main body part with a superposition part that simply turns up and down, the display part is also concealed in a superposition state where the operation part is concealed although it can be folded and compactized. In many cases, the structure is inconvenient and the use in a compact state must be restricted.

  In addition, the display part is concealed in the closed state that is overlapped for compactness, and the display part is placed on the front side when it is erected by opening and turning the overlapping part during use, so it is easy to see the display part, When it is difficult to show the display part to a person, and the camera part is provided on the opposite side of the display part, if you want to display your face on the display part, etc. Therefore, it is difficult to shoot and the shutter operation is difficult.

  Therefore, the applicant is configured to be able to turn the front and back by rotating further at a predetermined angle in the middle of opening or at a predetermined angle in the middle of opening, and in other words, even when folded without using a key operation, for example, Even in a compact state where the operation unit is concealed by superimposing the overlapped part with the display unit on the main unit, the display unit can be concealed with the operation unit with the display unit facing down as before. The display unit is arranged on the upper side so that the display unit can be seen and functioned even in a compact closed state, and can be reversed at a predetermined angle when the overlapping unit is raised when using the camera. I proposed something that I made.

  In particular, the display part (overlapping part) that opens and closes by undulating rotation can be provided in a reversible manner, and the display part can be made compact with the display part on the top surface. By providing the unit, it is possible to take a camera while looking at the display unit in a compact state, and it can be designed to be used exactly the same as a digital camera by flipping and folding while it is a mobile phone. .

  In other words, it breaks the conventional fixed concept that opens and closes only by undulating rotation, and it is configured so that the opened overlapped part can be turned upside down by further rotation and folded when not in use or requiring no key operation. At the same time, the display part can be concealed with the operation part with the display part facing down as before, or the display part is arranged on the upper side by rotating and reversing, and the display part can be visually recognized even in a compact closed state. It can be used like a digital camera by functioning as a display unit that projects video from the camera unit as described above, or further improved, for example, reversal rotated by rotation. The undulation rotation is restricted in the middle, for example, it can be reversed at a predetermined opening position, but cannot be rotated in the middle of other opening, and it can be reversed in the opened state. If it is not closed, it cannot be rotated, and the overlapped portion is closed in a twisted position, so that the operation unit can be pushed by mistake or the main body can be prevented from being damaged, and the usage of the device can be expanded. In addition, the hinges that can be easily opened and closed, are extremely easy to handle, can prevent malfunctions, have excellent durability, such as innovative mobile phones and mobile devices that are extremely practical. And an electronic device using the hinge device have been proposed (Japanese Patent Application No. 2000-40666, etc.).

  Such a hinge device has the following configuration (the same components as those of the present invention to be described later are described with the same reference numerals).

  The first member 2 (main body portion 2) and the second member 4 (overlapping portion 4) are pivoted up and down so as to be in an open state in which the overlapping surface is exposed by opening and rotating from the closed state where they are overlapped with each other, Further, the hinge device for connecting the overlapped surface and the exposed surface of the second member 4 so as to be able to be reversed and switched by making the second member 4 that rotates and rotates relative to the first member 2 relatively rotatable. H, one attachment portion 5 of the opening / closing rotation hinge portion HA provided with the undulating rotation shaft portion 9 is connected to the first member 2, and the other attachment portion 6 is connected to the rotation rotation shaft portion 16. The rotation rotation hinge portion HB is connected to the second member 4 via the rotation rotation hinge portion HB provided, and the rotation rotation hinge portion HB is provided so as to be freely raised and lowered by the opening / closing rotation hinge portion HA. Closed in which the second member 4 overlaps the first member 2 on the HA and the rotation pivoting hinge HB. The second member 4 is rotatable at least 180 degrees with respect to the first member 2 in a predetermined rotation position that is opened and rotated by a predetermined angle from the state or in an open state that is opened and rotated more than a predetermined angle; At least in the rotation position where the rotation is not more than the predetermined angle, the second member 4 is rotated relative to the first member 2 without twisting so that the second member 4 and the first member 2 can overlap. A rotation restricting mechanism S that cannot rotate or rotate at a predetermined angle or more from the rotation position is provided, and the rotation restricting mechanism S that is rotatable with respect to the undulating rotation shaft portion 9 of the opening / closing rotation hinge portion HA is provided. The rotation rotation shaft portion 16 is provided on the shaft mounting portion 10 of the rotation rotation hinge portion HB so as to be capable of rotation rotation, and the end portion of the rotation rotation hinge portion HA that protrudes to the inside of the shaft attachment portion 10 The second member 4 rotates and rotates together with the rotation of the second member 4, and the A locking portion 7 is provided to turn up and down by the up-and-down rotation of the second member 4, and the regulating portion 8 that restricts the rotation and up-and-down rotation of the locking portion 7 is provided inside the shaft mounting portion 10. The shaft mounting portion 10 is provided on the undulating rotation shaft portion 9 of the opening / closing rotation hinge portion HA provided rotatably. The shaft mounting portion 10 is a U-shaped member, and both leg portions 10A of the U-shaped member are rotatably provided on the undulating rotation shaft portion 9, and the rotation rotation shaft portion 16 is rotated on the erection portion 10B. The outer surface of the undulating rotation shaft portion 9 between the leg portions 10A on the inner side of the U-shaped shaft mounting portion 10 is designed in the following shape. That is, at the rotation rotation position where the first member 2 and the second member 4 can overlap, the second member 4 is allowed to rotate up and down, and the first member 2 and the second member 4 are rotated at a predetermined angle from the closed state where they overlap each other. The second member 4 is allowed to be rotated and rotated at least 180 degrees with respect to the first member 2 in the opened position in which the second member 4 is opened or rotated more than a predetermined angle. In the rotation position where the above-mentioned rotation is not performed, the second member 4 is moved from the rotation rotation position where the second member 4 and the first member 2 can overlap with each other with respect to the first member 2. The rotation restricting mechanism S is configured by setting the outer surface shape of the restricting portion 8 with respect to the locking portion 7 so that the rotation cannot be rotated or the rotation cannot be rotated more than a predetermined angle.

  For example, the locking portion 7 rotates and rotates with respect to the restricting portion 8 together with the rotation of the overlapping portion 4, and revolves and rotates with respect to the restricting portion 8 together with the undulating rotation of the overlapping portion 4. The portion 7 has a flat plate shape or a concave shape having a short diameter portion and a long diameter portion such as a drum shape or an ellipse shape, and the restriction portion 8 has a concave shape for receiving it. The shape of the locking portion 7 and the regulating portion 8 is not limited to this, and can be designed in various ways. For example, the locking portion 7 has a flat plate shape having a long side portion and a short side portion with respect to the rotation surface of rotation. In this case, the restricting portion 8 is formed by providing a concave portion between the large diameter portions of the undulating rotation shaft portion 9 (the central portion of the large diameter undulating rotation shaft portion 9 is dug) Although the restricting portion 8 is formed on the outer surface portion of the undulating rotation shaft portion 9), when the locking portion 7 is disposed at a position where it should be able to rotate and rotate, a sufficient diameter in all directions is allowed to allow this. In order to allow the undulation to rotate in a predetermined rotation direction, and to allow the revolving movement (undulation rotation) of the locking portion 7 in the rotation direction of the undulation rotation shaft portion 9, The recess portion and the recess space are formed so as to be continuous with each other, and the continuous recess portion that allows the undulation rotation is prevented from rotating and rotating. Wider but a narrow shape from the long side portion.

  As another example, the engaging portion 7 has a concave surface whose bottom surface escapes the undulating rotation shaft portion 9 so that the undulation rotation shaft portion 9 can be revolved in the undulation rotation direction while covering the undulation rotation shaft portion 9 during the undulation rotation. At this time, the rotation is prevented and the rotation is prevented, but it can be designed in various ways, such as being configured so that the rotation is not blocked by a wide recess in all directions at the fully swung position. It is.

  That is, for example, until the overlapping portion 4 is swung up and down 90 degrees, the overlapping portion 4 cannot rotate due to the engaging portion 7 hitting the restricting portion 8 and cannot rotate, and for example, the main body portion 2 and the overlapping portion 4 are overlapped. At a position where there is no twist (0 degree, 180 degree automatic rotation position), the position is rotated up and down within the restricting portion 8 and does not interfere with the restricting portion 8, but also, for example, a position where the 90 degree overlapping portion 4 is rotated and rotated. Then, it is possible to configure so that the locking portion 7 completely contacts the restricting portion 8 and cannot be closed and rotated beyond the substantially raised position (the rotation position where the main body portion 2 and the overlapping portion 4 are substantially perpendicular). is there.

  Therefore, by configuring the hinge device as described above, the undulation rotation is restricted during the reversal that is rotated and rotated, for example, it can be reversed at the open position, but the rotation cannot be rotated during the opening, and the open state is not achieved. It is not possible to rotate and rotate while the reversal is in progress, but it is possible to prevent the operation part from being accidentally pushed or damaged by closing the overlapped part in the twisted position. Applications are widespread, and the opening and closing operations are easy, extremely easy to handle, prevent malfunctions, have excellent durability, such as innovative mobile phones and mobile electronic devices, and these It becomes the hinge device used for.

  However, in order to make the display portion easy to see, the maximum opening angle in the undulating rotation of the overlapping portion is not 180 degrees but is slightly smaller than 180 degrees, for example, set to about 160 to 170 degrees.

  The maximum opening position restriction for the undulation rotation of this overlapping part is provided with a stopper to prevent over-rotation at the rotation part of the hinge device, or an uneven cam engagement structure to hold the angle in the hinge device and click hold However, in this proposal, the locking portion that restricts the undulation rotation and rotation rotation of the overlapping portion and the shape setting of the restriction portion prevent over-rotation, and the maximum opening in this undulation rotation is achieved. The position is determined so as to be regulated.

  Therefore, in the existing structure, in order to make the display part easy to see, the overlapped part turns up and down only to an angle slightly smaller than 180 degrees in a state where it is fully opened, and the display part is slightly inclined toward the front side and is set to be easy to see.

  Therefore, even if such a superposition part rotates and rotates by 180 degrees and the direction of the display part is reversed, the maximum opening position is still slightly smaller than 180 degrees, and it is opened only to a slightly inclined state.

  However, there are various inconveniences when opening only to an angle slightly smaller than 180 degrees even at the time of reversal.

  For example, when used as a mobile phone as described above, the overlapping part can be folded and polymerized to make it compact, and the overlapping part can be rotated and inverted to make it superimpose on the main body with the display part as the surface. It can be configured so that it can be used as a digital camera by configuring the camera unit to be provided on the bottom surface of this main body unit, but in this case, the camera unit that projects on the display unit is Provided on the outer surface (bottom side) of the main body.

  In such a case, if you want to take a picture of yourself, turn the folded overlapping part open and turn the overlapping part to rotate and reverse (fold the display part 3 upside down). Because it is already inverted in the compact digital camera specification, it is only necessary to open it as it is), but the display part is directed to the same side as the camera part on the outer surface of the main body, and the image reflected by the camera part is oriented in the same direction The convenience of being able to operate the shutter while visually recognizing on the display unit will be provided.

  However, in this case, since the maximum opening position of the overlapping portion can be opened only up to about 160 to 170 degrees for easy viewing of the display portion opened in normal use as described above, the opening cannot be rotated up to 180 degrees. Therefore, it has a drawback that it is difficult to see the display unit.

  In view of such a problem, the present invention aims to change the groundbreaking idea and easily improve, that is, by setting the shape relationship between the locking portion and the regulating portion that regulates the undulation rotation and the rotation rotation, For example, the maximum opening position in the undulation rotation of the overlapping part where the display unit is provided is regulated, and the maximum opening angle is increased in the undulation rotation before and after inversion, thus improving convenience. Accordingly, the present invention provides an innovative hinge device that can be used in various ways and is extremely practical, and an electronic device using the hinge device.

  The gist of the present invention will be described with reference to the accompanying drawings.

When the locking portion 7 is swung up and down with respect to the restricting portion 8 due to the up-and-down rotation, the locking portion 7 abuts against the restricting portion 8 and the over-rotation of the locking portion 7 is prevented, and the first In a state where the maximum opening position of the two members 4 is restricted and the second member 4 is rotated 180 degrees and the locking portion 7 is rotated 180 degrees, the locking portion 7 is still in the maximum opening position. The maximum opening angle at the time of reversal of the second member 4 is set to a shape that increases more than before reversal without hitting 8. Those of the hinge device to be.

  In addition, when the second member 4 is swung up and down and the locking portion 7 is swung up and down, the bottom surface of the restricting portion 8 against which the bottom surface of the locking portion 7 abuts at the maximum open position or the engagement. A convex portion 30 is provided on the bottom surface of the stop portion 7, and the bottom surface of the locking portion 7 or the undulation rotation prevention outer surface of the restricting portion 8 abuts against the convex portion 30, thereby preventing the overturning of the locking portion 7. The rotation position at which the locking portion 7 abuts against the restriction portion 8 is configured to be the maximum opening position of the second member 4, and the second member 4 is rotated by 180 degrees to the restriction portion 8. On the other hand, when the locking portion 7 is rotated 180 degrees relative to the restricting portion 8, the locking portion at a position where the locking portion 7 is engaged with the convex portion 30 when the locking portion 7 is swung up and down.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention that are considered suitable (how to carry out the invention) will be briefly described with reference to the drawings, illustrating the operation of the present invention.

  For example, in the open state in which the second member 4 (overlapping portion 4) is rotated by 180 degrees with respect to the first member 2 (main body portion 2) in the open state in which the open state is rotated by a predetermined angle or more from the closed state, the closed rotation is again performed. By setting the closed state overlapping each other, the exposed surface and the bottom surface of the overlapped portion 4 in the closed state can be reversed and switched, and the twisted position in the middle of the 180 ° reverse rotation by rotating the overlapped portion 4 in the open state. In this case, it can be designed so that at least the angle at which the end of the overlapping portion 4 comes into contact with the upper surface of the main body 2 cannot be closed and rotated.

  Further, for example, the locking portion 7 that rotates and rotates together with the rotation of the superimposing portion 4 and moves up and down together with the rotation and rotation hinge device HB by the up and down rotation of the overlapping portion 4 is connected to the rotation rotation axis of the rotation and rotation hinge portion HB. An end of the portion 16 is provided in the shaft mounting portion 10, and the restricting portion 8 for restricting the rotation and undulation rotation of the locking portion 7 is provided as the undulation of the opening / closing rotation hinge HA on the main body 2 side. For example, in the rotation rotation position where the main body portion 2 and the overlapping portion 4 can be overlapped, the locking portion 7 does not interfere with the restricting portion 8 and does not interfere with the restricting portion 8. In the open state in which the movement is allowed and the open state is rotated by a predetermined angle from the closed state where they are overlapped with each other, the overlapping portion 4 is similarly allowed to rotate 180 degrees with respect to the main body portion 2, but it is allowed to rotate more than the predetermined angle. At the rotation position where the opening is not rotated, the movement of the locking portion 7 is obstructed by the restricting portion 8 and is The overlapping portion 4 and the main body portion 2 can be overlapped and closed to the main body portion 2 without being twisted at all times during the closing rotation, for example, the rotation rotation of a predetermined angle or more is prevented from the rotation position without twisting that can be overlapped with the main body portion 2. The shape of the restricting portion 8 with respect to the locking portion 7 can be set so that the end portion of the overlapping portion 4 does not come into contact with the upper surface of the main body 2 when the twisted portion is twisted.

  In the present invention, the maximum opening position in the undulating rotation of the overlapping portion 4 with respect to the main body portion 2 is restricted by the shape setting of the locking portion 7 and the restricting portion 8.

  That is, the restricting portion 8 prevents the locking portion 7 from rotating up and down, thereby preventing the overlapping portion 4 from excessively rotating and determining the maximum opening angle of the overlapping portion 4.

  The shape of the locking portion 7 and the regulating portion 8 is the same as that when the locking portion 7 is swung up and down with respect to the regulating portion 8 by the up-and-down rotation of the overlapping portion 4 with respect to the main body 2. 7 abuts against the restricting portion 8 to prevent over-rotation of the locking portion 7 and the maximum opening position of the second member 4 is restricted, and the second member 4 rotates and rotates 180 degrees. In a state where the portion 7 is rotated by 180 degrees, the locking portion 7 is not yet in contact with the restricting portion 8 at the maximum opening position, and the maximum opening angle when the overlapping portion 4 is reversed is set to be larger than that before reversal. did.

  For example, as in Example 1 described later, when the overlapping portion 4 is swung up and down and the locking portion 7 is swung up and down, the bottom surface of the locking portion 7 abuts at the maximum open position. A convex portion 30 is provided on the undulating rotation preventing outer surface or the bottom surface of the engaging portion 7, and the bottom surface of the engaging portion 7 or the undulating rotation preventing outer surface of the restricting portion 8 abuts against the convex portion 30. An excessive rotation is prevented, and the rotation position where the locking portion 7 abuts against the restriction portion 8 is configured to be the maximum opening position of the overlapping portion 4, and the overlapping portion 4 is rotated 180 degrees. In a state where the locking portion 7 rotates and rotates 180 degrees relative to the restriction portion 8 with respect to the restriction portion 8, a position where the engagement portion 7 engages with the convex portion 30 when the locking portion 7 is rotated up and down. A concave portion 31 is provided on the bottom surface of the locking portion 7 or on the outer surface of the restricting portion 8 to prevent undulation rotation. Opening rotation angle of the maximum opening position by engagement is constructed as later reversed from the previous inversion is increased.

  Therefore, for example, when configured and used as a mobile phone as described above, the overlapping portion 4 can be folded and overlapped to be compact, and the overlapping portion 4 can be rotated and reversed so that the display portion 3 faces the main body portion 2. In this case, it can be used as a compact digital camera by providing a camera unit 32 on the bottom surface of the main body unit 2. The camera unit 32 projected on the display unit 3 is provided on the outer surface (bottom surface) of the main body.

  Even in such a case, when taking a picture of himself / herself, the folded overlapping portion 4 is opened and rotated, and the overlapping portion 4 is rotated and reversed (the display portion 3 is turned to the front side). Since it has already been reversed in the compact digital camera specification that is folded, the display unit 3 faces the same side as the camera unit 32 on the outer surface of the main unit 2 and is reflected by the camera unit 32 itself. Is provided with the convenience of being able to operate the shutter while visually recognizing with the display unit 3 in the same orientation. In addition, since the display unit 3 is pivoted to open more than before reversal, for example, by 180 degrees, the display unit 3 can be largely pivoted to open if the display unit 3 is reversed unlike before. It becomes an innovative mobile phone, mobile electronic device and the like, and a hinge device used in these, which are extremely practical, such as being easy to see.

  A first embodiment of the present invention will be described with reference to the drawings.

  In this embodiment, the present invention is applied to a mobile phone that can be made compact in size. On the upper surface side of a plate-like main body 2 (first member 2) in which electronic parts such as a circuit board and a power source are housed in a case. An operation unit 1 that performs a keyboard function in which numeric keys and function keys are arranged is provided, and a substantially overlapping plate-like overlapping unit 4 (second member 4) that overlaps the main body unit 2 and covers the operation unit 1 is undulated. It is configured to be pivotally connected by a hinge device H so as to be movable.

  A display unit 3 such as a liquid crystal panel on which a predetermined display is made or a predetermined display is made by the operation of the operation unit 1 or an incoming call is provided on the lower surface side (lower surface) of the overlapping unit 4.

  The connection between the main body portion 2 and the overlapping portion 4 is made by connecting the overlapping portions of both end portions to the undulating rotation shaft portion 9 arranged in the width direction and the rotation turning shaft arranged in the direction orthogonal thereto. Connected by a biaxial hinge device H having a portion 16, the overlapping portion 4 can rotate up and down as usual, and can rotate and rotate 180 degrees in the left and right directions (reversible), and can rotate 180 degrees as an open state. By doing so, the front and back directions of the overlapping portion 4 can be switched, and the concealed surface and the exposed surface of the overlapping portion 4 in the closed state where they are overlapped with each other can be reversed.

  Further, a camera unit 32 is provided on the bottom surface of the main body 2, that is, the outer surface of the overlapping portion 4 of the main body 2, and an image of the camera portion 32 is configured to be displayed on the display unit 3 of the overlapping portion 4. Thus, the display unit 3 is arranged on the outer surface, and the superposition unit 4 is superposed on the operation unit 1 so that it can be used as a digital camera in a compact state.

  Next, the hinge apparatus H of a present Example is demonstrated.

  In the present embodiment, as described above, the main body portion 2 and the overlapping portion 4 are overlapped with each other to be opened to a predetermined angle with the undulating rotation shaft portion 9 as an axis, thereby opening the overlapping surface. Thus, the overlapping portion 4 and the exposed surface of the overlapping portion 4 can be rotated freely about the rotation rotation shaft portion 16 as the rotation rotation shaft portion 16. Is a hinge device H that is connected so as to be capable of being reversed and switched, wherein one attachment portion 5 of the opening / closing rotation hinge portion HA including the undulating rotation shaft portion 9 is connected to the main body portion 2 and the other attachment portion 6 is connected. Is connected to the overlapping portion 4 via a rotation rotation hinge portion HB provided with the rotation rotation shaft portion 16, and the rotation rotation hinge portion HB is undulated and rotated (revolved) by the opening / closing rotation hinge portion HA. It can be freely rotated, and the open / close rotation hinge portion HA and the rotation rotation hinge portion HB are closed. In the rotation range (open state) in which the rotation portion is opened and rotated more than a predetermined angle from the main body portion 2, the overlapping portion 4 can be rotated forward and backward by 180 degrees with respect to the main body portion 2, and the rotation that is opened and rotated to the predetermined angle. In a rotation position that does not reach the position, a rotation restriction mechanism S is provided in which rotation is prevented and rotation is impossible for a predetermined angle or more, and a state where there is no twist that overlaps with each other is held and restricted. .

  That is, in this embodiment, in the open state in which the rotation is opened by a predetermined angle or more from the closed state, the overlapping portion 4 is rotated 180 degrees with respect to the main body portion 2 and is again closed and rotated to overlap each other. By doing so, it is possible to reversely switch the exposed surface and the bottom surface of the overlapped portion 4 in the closed state, and when the overlapped portion 4 rotates in the open state and is in a twisted position in the middle of the 180-degree reverse rotation, The rotation restricting mechanism S is configured so that at least the angle at which the end of the overlapping portion 4 comes into contact with the upper surface of the main body 2 cannot be closed and rotated.

  Specifically, the rotation portion of the rotation rotation hinge portion HB rotates the locking portion 7 that rotates and rotates together with the rotation rotation of the overlapping portion 4 and moves up and down together with the rotation rotation hinge device HB by the rotation of the overlapping portion 4. This rotation rotation shaft portion 16 is provided at the end of the moving shaft portion 16 in a U-shaped shaft mounting portion 10 provided to freely rotate, and the rotation and undulation rotation of the locking portion 7 is restricted ( A restricting portion 8 that is allowed / blocked) is provided on the undulating rotation shaft portion 9 of the opening / closing rotation hinge portion HA on the side of the main body portion 2, so that the main body portion 2 and the overlapping portion 4 can overlap with each other and rotate without rotation. Then, the overlapping portion 4 is allowed to turn up and down without the locking portion 7 interfering with the restricting portion 8, and similarly in the open state in which the overlapping portion is rotated more than a predetermined angle from the closed state where they overlap each other. 4 is allowed to rotate 180 degrees with respect to the main body 2 by rotating 180 degrees more than a predetermined angle. In the non-rotating position, the movement of the locking portion 7 is obstructed by the restricting portion 8, and the rotation rotation beyond a predetermined angle is prevented from the non-twisting rotation position where the overlapping portion 4 and the main body portion 2 can overlap. Thus, the shape of the restricting portion 8 with respect to the locking portion 7 is set so that the end portion of the overlapping portion 4 does not come into contact with the upper surface of the main body portion 2 during the closing rotation.

  That is, in the present embodiment, the space (the space for disposing the locking portion 7) that allows the rocking and rotating shaft portion 9 of the opening and closing rotation hinge portion HA of the present embodiment to rotate and rotate the locking portion 7. ) As a restriction portion 8.

  More specifically, a shaft mounting portion 10 (base portion 10) that serves as a mounting seat base for the rotation rotation shaft portion 16 of the rotation rotation hinge portion HB is formed in a U-shape, and the opposite leg portions of the base portion 10 are formed. 10A is provided with a shaft support hole 10C hole through which the undulating rotation shaft portion 9 is inserted, and a shaft hole through which the rotation rotation shaft portion 16 is inserted in the upper piece portion (erection portion 10B).

  First, the opening / closing rotation hinge portion HA will be described. The undulating rotation shaft portion 9 inserted through the base portion 10 is disposed in a non-rotating cylindrical case 12 disposed on the side of the base portion 10. In the cylindrical case 12, at least one of the cam portion 13 and the cam engaging portion 14 that engage with each other with the undulating rotation shaft portion 9 as an axis is slidably mounted so as to be rotatable relative to each other. 12 is engaged with the first member 2 via the attachment portion 5, and the opposite end of the undulating rotation shaft portion 9 is also engaged with the first member 2. Therefore, in the predetermined undulation rotation position, it is configured to be positioned (cam lock) by the cam engagement bias and the engagement bias by the spring 11. For example, in the closed state, the cam is biased in the middle of the cam engagement. In the open state, cam engagement is held (cam lock), and in the middle of up and down rotation, a rotation resistance is generated by spring bias, and a free stop that holds the released rotation position is realized. Yes.

  In the present embodiment, the cam portion 13 that is inserted through the undulation rotation shaft portion 9 and rotates together is slidably mounted in the cylindrical case 12, and the other cam engagement portion 14 is attached to the undulation rotation shaft 9. Concavities and convexities are formed on one opposing leg portion 10A of the base portion 10 that undulates and rotates relative to the base portion 10 to form a cam engaging portion 14 itself.

  Further, the concave portion is formed in the undulating rotation shaft portion 9 between the opposing leg portions 10A, and the restricting portion 8 is provided.

  Then, the overlapping portion 4 is connected to the base portion 10 that rotates up and down with respect to the main body 2 (the cylindrical case 12 and the up-and-down rotation shaft portion 9) via the rotation-rotation hinge portion HB. ing.

  The rotation rotation hinge portion HB provided with the rotation rotation shaft portion 16 is attached to one end (upper end) of the shaft hole of the upper piece portion (erection portion 10B) of the base portion 10 (shaft attachment portion 10). It connects with the superposition | polymerization part 4 via the part 6, and the rotation rotation shaft part 16 which provided the said latching | locking part 7 in the other end (lower end) is inserted, This rotation rotation shaft part 16 (and the said attachment part 6) In this embodiment, a cam engagement portion 18 that is inserted into the cam portion 17 that is prevented from rotating and is engaged with the cam portion 17 is provided on the upper piece (the erection portion 10B) of the base portion 10 so as to be uneven. The cam portion 13 is slidably provided along the rotation rotation shaft portion 16 and is configured to be engaged and biased by a spring 19.

  Accordingly, the overlapping portion 4 rotates and rotates about the rotation and rotation shaft portion 16 and is cam-locked in a rotation direction that cannot be twisted by the cam engagement between the cam portion 17 and the cam engagement portion 18 so that the overlapped state can be achieved. It is configured as follows.

  In addition, when rotating 180 degrees from a direction without twisting, the cam portion 17 is separated from the cam engaging portion 18 and rotates relative to the spring 19, and is rotated at 0 ° and 180 ° inversion positions. In the same manner as the opening / closing rotation hinge part HA, the cams are locked by engaging the projections and recesses, and a free stop is realized by a spring bias at the middle position of the rotation so that the closing rotation is possible. It is positioned at the 0 degree and 180 degree rotation positions, and is configured not to wobble and rotate.

  Further, in this embodiment, the cam portion 17 or the cam portion 17 (the rotation rotation shaft portion 16) is not rotated more than approximately 180 degrees so that the wiring is not hindered, and the cam portion 17 or the cam portion 17 can rotate freely in this range. In addition, a stopper portion 20 that abuts and engages with the rotating member and the cam engaging portion 18 or a member integrated therewith is provided.

  Further, in this embodiment, the locking portion 7 rotates and rotates with respect to the restricting portion 8 with the rotation of the overlapping portion 4, and revolves with respect to the restricting portion 8 with the undulating rotation of the overlapping portion 4. However, the engaging portion 7 has a flat plate shape or a concave shape having a short diameter portion and a long diameter portion such as a drum shape or an elliptical shape, and the restriction portion 8 has a concave shape for receiving the same. The shape of the engaging portion 7 and the restricting portion 8 is not limited to this, and can be designed in various ways. For example, the engaging portion 7 has a long side portion and a short side portion with respect to the rotation surface. In this case, the restricting portion 8 is formed in a recessed state between the large diameter portions of the restricting portion forming member 8A that is coaxial with the undulating turning shaft portion 9, but is locked at a position where it should be able to rotate and rotate. When the portion 7 is arranged, a concave shape having a sufficient diameter on all four sides is allowed to allow this, and the rotation direction of the undulation rotation shaft portion 9 is allowed to allow the undulation rotation in a predetermined rotation rotation direction. The recess portion that allows the revolving movement (undulation rotation) of the locking portion 7 to the recess portion, the recess space and the recess space are formed so as to be connected to each other. In order to prevent rotation, the shape is wider than the short side but narrower than the long side.

  As another example (Embodiment 2), the engaging portion 7 is formed in a concave shape whose bottom surface escapes the undulating rotation shaft portion 9, and the undulating rotation shaft portion 9 is covered and disposed during the undulation rotation. In this case, the rotational rotation is obstructed and the rotational rotation is prevented, but the rotational rotation is prevented by the wide recesses in the four directions at the fully swung position. Various designs are possible.

  That is, for example, until the overlapping portion 4 is swung up and down 90 degrees, the overlapping portion 4 cannot rotate due to the engaging portion 7 hitting the restricting portion 8 and cannot rotate, and for example, the main body portion 2 and the overlapping portion 4 are overlapped. At a position where there is no twist (0 degree, 180 degree automatic rotation position), the position is rotated up and down within the restricting portion 8 and does not interfere with the restricting portion 8, but also, for example, a position where the 90 degree overlapping portion 4 is rotated and rotated. Then, it is configured such that the locking portion 7 completely contacts the restricting portion 8 and cannot be closed and rotated beyond the substantially raised position (the rotation position where the main body portion 2 and the overlapping portion 4 are substantially perpendicular).

  More specifically, in this embodiment, in the open state in which the positioning is locked by the cam engagement by the opening / closing rotation hinge part HA (and the rotation position in the open state until reaching the substantially raised position), The stop portion 7 can freely rotate 180 degrees forward and reverse without interfering with the restricting portion 8, and the direction of the locking portion 7 undulates when closing and turning from the open state where the cam lock is performed. In the open state, when the overlapped portion 4 is rotated and rotated, the latching portion 7 interferes with the restricting portion 8 and the above-mentioned open rotation position or more Therefore, the overlapping portion 4 is configured so as not to be closed and rotated when it cannot be closed and rotated.

  Accordingly, the rotation of the closed portion in the twisted state is also prevented, and the rotation of the rotation in the twisted direction in the middle of the closed rotation in the correct direction is also prevented. It is configured so that it can be prevented from striking against the portion 2, and the operation portion 1 on the main body portion 2 can be prevented from being pushed by mistake.

  Further, by chamfering the end portion of the restricting portion 8 to a predetermined shape, when the overlapping portion 4 is closed and rotated at a slightly twisted rotation position, the overlapping portion 4 is automatically aligned along the upper end shape of the restricting portion 8. Can be configured to rotate and rotate in the correct orientation and close the polymerization, and as described above, it can be rotated to any open range, and if it is twisted, it can be blocked and rotated beyond what position. Moreover, it will be possible to make fine adjustment settings.

  Therefore, it is possible to easily prevent the end corner of the overlapping portion 4 from contacting the main body 2 as described above by closing and rotating the overlapping portion 4 even though the overlapping portion 4 is in the twisted position. In addition, in the present embodiment, it is possible to easily realize the rotation restriction as described above by setting the shapes of the locking portion 7 and the restriction portion 8, so that this rotation restriction can be easily made into various variations. It can be designed.

  Further, in the present embodiment, as described above, the second member 4 rotates and rotates at the end protruding to the inside of the shaft attachment portion 10 of the rotation rotation hinge portion HA, and the second rotation is performed. A locking portion 7 is provided to turn up and down by the up-and-down rotation of the two members 4. A restricting portion 8 that restricts the rotation and up-and-down rotation of the locking portion 7 is provided inside the shaft mounting portion 10. The shaft mounting portion 10 is provided on the undulating rotation shaft portion 9 of the opening / closing rotation hinge portion HA provided so as to be rotatable. The restricting portion 8 has an outer surface of the rotation shaft portion 16 formed in a predetermined shape. The undulation rotation shaft portion 9 is connected to a restriction portion forming member 8A having an outer surface formed in a predetermined shape without being integrally formed with the undulation rotation shaft portion 9, and the restriction is applied to the undulation rotation portion 9 by another part. The portion 8 is provided.

  That is, the shaft mounting portion 10 is a U-shaped member, and both leg portions 10A of the U-shaped member are rotatably provided on the undulating rotation shaft portion 9, and the rotation rotation shaft portion 16 is provided on the erection portion 10B. Is provided such that the restricting portion forming member 8A is disposed between the leg portions 10A on the inner side of the U-shaped shaft mounting portion 10, and the undulating rotation shaft portion 9 is pivotally supported by both leg portions 10A. The shaft mounting portion 10 is rotatably provided on the undulating rotation shaft portion 9 through the hole 10C, and, for example, the undulating rotation shaft portion 9 is connected to the shaft connecting hole 8B of the restricting portion forming member 8A. The restricting portion 8 may be provided on the undulating rotation shaft portion 9 between the leg portions 10A.

  Therefore, unlike the conventional configuration, the undulating rotation shaft portion 9 and the restricting portion 8 are separate parts, that is, the predetermined portion of the undulating rotation shaft portion 9 is integrally formed or processed into a predetermined shape. As a separate part from the undulating and rotating shaft part 9, the undulating and rotating shaft part 9 is passed through the restriction forming member 8A disposed between the leg parts 10A of the shaft mounting part 10 or the undulating and turning shaft part 9 is placed on the side. The restricting portion 8 is provided on the undulating rotation shaft portion 9 by connecting the undulating rotation shaft portion 9 to the restricting portion forming member 8A provided separately from the undulating rotation shaft portion 9 by being inserted and connected from the side. Since the configuration is such that the undulating rotation shaft portion 9 is thin, the restricting portion forming member 8A can be designed large. As a result, since the undulating rotation shaft portion 9 is thin, it is inserted into the leg portion 10A (the shaft support hole 10C) of the shaft mounting portion 10 as before, and the shaft mounting portion 10 is provided rotatably on the undulating rotation shaft portion 9. However, even if the outer diameter of the restricting portion forming member 8A is increased, it is not necessary to pass the restricting portion forming member 8A through the leg portion 10A (the shaft support hole 10C). A large restricting portion forming member 8A (a restricting portion forming member 8A capable of forming a deep concave portion) can be arranged inside the shaft attaching portion 10 without increasing the shaft attaching portion 10 and the shaft for rotating the undulations. In order to connect the part 9 and the restricting part forming member 8A, the restricting part 8 can be provided on the undulating rotation shaft part 9 as before.

  Therefore, it is possible to form a sufficiently deep concave portion in the restricting portion forming member 8A with a configuration that can be made compact as in the past, and a contact surface (step surface) that prevents the locking portion 7 from rotating can be formed sufficiently high. The revolutionary hinge device and the electronic device using the hinge device that can reliably prevent the rotation of the portion 7 and have excellent durability can be easily realized by this simple improvement.

  Further, in this embodiment, the restricting portion forming member 8A disposed on the leg portion 10A of the shaft attaching portion 10 is provided with the undulating rotation shaft portion 9 inserted through the shaft support hole 10C of the leg portion 10A. Although the configuration has been described in which the undulation rotation shaft portion 9 and the restriction portion forming member 8A are connected through the shaft connection hole 8B, the undulation rotation shaft portion 9 is provided on the restriction portion formation member 8A disposed between the leg portions 10A. The shaft connecting holes 8B that are inserted and connected to the undulating rotation shaft portions 9 that pass through the shaft supporting holes 10C of the left and right leg portions 10A are provided on the left and right sides of the restricting portion forming member 8A. It is good also as a structure which connects the raising / lowering rotation shaft part 9 and the control part formation member 8A of the center, and provides the restriction part 8 in the raising / lowering rotation shaft part 9. FIG. In this embodiment, the restricting portion forming member 8A does not require a through hole, and therefore there is no through shaft in the center portion. Therefore, a deep recess can be formed in the restricting portion forming member 8A. The hitting step can be designed to be higher (deeper), the locking portion 7 can be reliably controlled, and the functions and effects of the present invention with excellent durability can be exhibited well. This example illustrates this type as Example 1.

  In the present embodiment, the undulation rotation shaft portion 9 of the opening / closing rotation hinge portion HA or the member provided in the axial direction of the undulation rotation shaft portion 9, the circuit portion provided in the first member 2, and the second A wiring winding part 22 for winding a wiring 21 that electrically connects a circuit part provided in the member 4 is provided.

  That is, a part of the undulation rotation shaft portion 9 of the opening / closing rotation hinge portion HA or a portion provided in this axial direction, on a side portion of the restriction portion 8, and on the outer periphery of the winding space of the wiring 21 The wiring winding part 22 is provided so as to form a part where the resistance is secured.

  Specifically, the undulating rotation shaft portion 9 extended to the opposite side to the side where the cam engaging lock mechanism (cylindrical case 12) of the base portion 10 is provided is engaged with the first member 2, but this is not the case. The side is simply configured to extend the undulating rotation shaft portion 9, that is, the extended shaft portion is not provided with a cam engagement mechanism, and this extended portion (a part of the undulating rotation shaft portion 9) is wound by wiring. It is referred to as round part 22.

  In other words, in this embodiment, a wiring winding portion 22 is provided on one side of the undulating rotation shaft portion 9 as a winding portion for fixing and holding the wiring 21, specifically, the flexible wiring several times. On the other hand, a wire 21 that electrically connects the circuit portion provided in the first member 2 and the circuit portion provided in the second member 4 is also wound around the rotation rotation shaft portion 16 of the rotation rotation hinge portion HB. A wiring winding part 22 is provided.

  That is, the winding ring 23 is fitted on the rotation rotation shaft portion 16, and this is also used as the wire winding portion 22. Therefore, the present invention can be easily wired without hindering such an opening / closing operation and a regulating operation.

  In such a configuration, in the present embodiment, the shape of the locking portion 7 and the restricting portion 8 is changed by the undulating rotation of the second member 4 (overlapping portion 4) with respect to the first member 2 (main body portion 2). When the locking part 7 is swung up and down with respect to the restricting part 8, the locking part 7 hits the restricting part 8, and the overturning of the locking part 7 is prevented, and the overlapping part 4 is turned up and down. In the state where the maximum opening position in movement is restricted and the overlapping portion 4 is rotated 180 degrees and the locking portion 7 is rotated 180 degrees, the locking portion 7 is still in the maximum opening position in the undulation rotation. The maximum opening angle at the time of reversal of the overlapping portion 4 is set to be larger than that before reversal. That is, when the overlapping portion 4 is swung up and down and the locking portion 7 is swung up and down, the convex portion 30 is formed on the hulling and rotation preventing outer surface of the restricting portion 8 where the bottom surface of the locking portion 7 abuts at the maximum open position. When the bottom surface of the locking portion 7 abuts against the convex portion 30, excessive rotation of the locking portion 7 is prevented, and the rotation position where the locking portion 7 abuts against the restriction portion 8 is the second position. The overlapping portion 4 is rotated by 180 degrees and the locking portion 7 is rotated by 180 degrees with respect to the restricting portion 8. In this state, when the locking portion 7 is swung up and down, a recess 31 is provided on the bottom surface of the locking portion 7 at a position where the locking portion 7 is engaged, and the recess 31 is engaged with the protrusion 30. Thus, the opening rotation angle at the maximum opening position in the undulation rotation is configured to increase after reversal than before reversal.

  In the first embodiment, the maximum opening angle at the maximum opening position in the above-described undulation rotation is set to be about 165 degrees by the convex portion 30. When the overlapping portion 4 is inverted, the convex portion 30 is reversed. The maximum opening angle is set to be approximately 180 degrees by escaping through the recess 31. That is, one side of the bottom surface of the locking portion 7 is a flat surface, and this flat surface is provided on the outer surface of the restriction portion 8 that prevents the rotation of the locking portion 7 when the locking portion 7 is swung with respect to the restriction portion 8. The concave portion 31 is provided on the opposite side of the bottom surface of the locking portion 7 so that the convex portion 30 engages (displaces), and the overlapping portion 4 is reversed to form the locking portion 7. In the state of rotating 180 degrees, the convex portion 30 and the concave portion 31 are engaged with each other, and the concave bottom surface of the concave portion 31 hits the convex portion 30 or the periphery of the concave portion 31 hits the periphery of the convex portion 30. Thus, the opening angle of the maximum undulation rotation position of the second member 4 is increased so that it can be opened up to about 180 degrees.

  Further, in the second embodiment, the bottom surface of the locking portion 7 is formed in a curved shape that escapes the restricting portion 8, and has a shape that allows undulation rotation (revolution movement) with respect to the restricting portion 8. The maximum opening angle is regulated by setting the end of the locking part 7 to protrude from the undulation rotation preventing outer surface of the regulating part 8, and the lengths from the centers of both ends of the locking part 7 are made different. When the locking portion 7 is reversed, the allowable range of undulation rotation until the abutment is made different so that the maximum opening angle in the undulation rotation at the time of reversal can be opened and rotated from about 160 to 170 degrees to about 180 degrees, and the maximum opening is possible. The angle is configured to increase after inversion compared to before inversion.

  Note that the present invention is not limited to the first and second embodiments, and the specific configuration of each component can be appropriately designed.
