Description

  The present invention relates to a hinge device provided at a pivotally mounted portion of an electronic device such as a mobile phone, a mobile phone, and a laptop computer, 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, If it is difficult to show the display part to the 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. This makes it difficult to shoot and shutter operation.

  Therefore, the applicant is configured so that it can be turned upside down by rotating and rotating 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 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. In addition, for example, undulation rotation is restricted during reversal that is rotated and rotated, for example, it can be reversed at a predetermined opening position, but rotation can be performed during other opening. In addition, it cannot be closed and rotated if it is in the middle of reversal in the open state, and the operation part is accidentally pushed or damaged by closing the overlapped part in the twisted position. It can also be used as an equipment device, and the opening and closing operation is easy, making it extremely easy to handle, preventing malfunctions, and having excellent durability, such as excellent durability. Proposed a hinge device capable of realizing electronic devices such as mobile phones and mobiles, and an electronic device using this hinge device (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 rotatably provided on the shaft attachment portion 10 of the rotation rotation hinge portion HB, and the end portion of the rotation rotation hinge portion HA protruding to the inside of the shaft attachment portion 5 The second member 4 rotates and rotates together with the rotation of the second member 4, and the front 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 restricting shapes of the engaging portion 7 and the restricting portion 8 are 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 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 state in which the central portion of the large diameter undulating rotation shaft portion 9 is dug) The restricting portion 8 is formed on the outer surface portion of the undulating rotation shaft portion 9), but when the locking portion 7 is disposed at a position where it should be able to rotate and rotate, the diameter is sufficient in all directions to allow this. And a recess shape that allows the revolving movement (undulation rotation) of the locking portion 7 in the rotation direction of the undulation rotation shaft portion 9 in order to allow the undulation rotation in a predetermined rotation rotation direction. The concave space and the concave space are formed so as to be continuous with each other, and the continuous concave portion that allows this undulation rotation is to prevent rotation and rotation, Wider than the side portions is 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 the case of a hinge device that is provided with a rotation restricting mechanism that includes a locking portion and a restricting portion that restricts the movement of the locking portion at the intersection of such a biaxial hinge, the circuit portion of one member When the flexible wiring that electrically connects the circuit portion of the other member is routed, for example, the wiring is once wound around the undulating rotation shaft portion 9 and is then wound around the rotation rotation shaft portion 16. In addition, the wiring is very troublesome because the two-axis rotation and the rotation restriction of the rotation restriction mechanism S must be routed so as not to cause any trouble. There is also a concern about the possibility of causing a problem, and for this reason, there is also a concern about durability.

  Further, in the configuration so far, the outer surface portion of the undulation rotation shaft portion 9 is formed in a predetermined shape corresponding to the engagement portion 7 (from the relationship with the engagement portion 7), and the undulation rotation shaft portion 9 is formed. A restricting portion 8 is formed.

  In other words, the restricting portion 8 is integrally formed on the undulation rotation shaft portion 9 by molding or processing the position corresponding to the locking portion 7 of the undulation rotation shaft portion 9 into a predetermined shape.

  On the other hand, however, a configuration in which the U-shaped shaft mounting portion 10 is rotatably provided on the undulating rotation shaft portion 9, that is, the undulating rotation shaft portion 9 is provided in the shaft support hole 10C provided in the leg portion 10A of the shaft mounting portion 10. The shaft mounting portion 10 is rotatably provided on the undulating rotation shaft portion 9, and the restriction portion 8 is integrally formed on the outer surface of the undulating rotation shaft portion 9 between the leg portions 10 </ b> A of the shaft mounting portion 10. .

  Therefore, in order not to make the undulation rotation shaft portion 9 itself thick, the step for recessing the outer surface portion of the undulation rotation shaft portion 9 cannot be made sufficiently large (the depression is deepened). In other words, the outer diameter (the maximum outer diameter of the restricting portion 8) of the undulating rotation shaft portion 9 itself that is a base for molding or processing the restricting portion 8 is restricted due to the need to pass the leg portion 10A, and the weight and cost are reduced. Since the diameter cannot be increased in order to suppress the increase, the deep recess cannot be formed (the restriction portion 8 cannot be formed by the deep recess), and therefore the step edge that prevents the locking portion 7 from rotating can be formed sufficiently high. Although it is possible to prevent the locking portion 7 from rotating as expected, there is a risk that strong turning force may be applied, or that the long-term use may prevent the step due to the recess from becoming insufficient due to wear or the like. May cause problems that cannot be achieved.

  In other words, the diameter of the undulating rotation shaft portion 9 (the restricting portion 8) is increased so that the shaft supporting hole 10C of the leg portion 10A of the shaft mounting portion 10 is enlarged to form the restricting portion 8 having a sufficiently deep recess. If this is passed through, the hinge mounting shaft 10 becomes taller and the hinge device cannot be made compact, the weight increases, the cost increases, and the undulating rotation shaft portion having such a restriction portion 8 is provided. 9 may be difficult to mold and process, and may cause various problems.

  Therefore, it has been unavoidable to have a configuration that requires various improvements such as processing accuracy of the restricting portion 8 formed on the undulating rotation shaft portion 9 and hardening / lightening of the material.

  In view of such problems, the present invention aims to change the groundbreaking idea and easily improve the wiring incorporated in the first member 2 and the second member 4 connected via the hinge device to the hinge shaft. The biaxial rotation and rotation of the rotation restricting mechanism S are configured so that the bent portion of the wiring can be accommodated in the restricting portion 8 of the rotation restricting mechanism S while being configured to wire through the shaft portion instead of being wound and wired. Wiring can be done very easily without causing any trouble in regulation, wiring failure is difficult to occur, and the regulation shape of the regulation part is easy, and a highly durable regulation shape with deep recesses and sufficient steps can be configured. Even if the diameter is increased, the hollow shape allows easy wiring, reducing weight and reducing costs. For example, once the wiring passed through one shaft is pulled out, the wiring is placed inside the next shaft. To pass And its object is to provide an electronic device using an innovative hinge device and hinge apparatus Xiu is extremely practical, such as enabling the easy.

  In addition, the restricting portion 8 is configured as a separate part from the undulating rotation shaft portion 9 by the restricting portion forming member 8A, so that the concave portion is deep without hindering compactness and weight reduction and the rotation of the locking portion 7 is ensured. A revolutionary hinge device and a hinge device that are more practical, such as the restriction portion 8 that can be locked and stopped with good durability and can be simply configured and arranged between the leg portions 10A of the shaft mounting portion 10 as before. It aims at providing the used electronic equipment.

  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 (the 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 opening is rotated by a predetermined angle or more from the closed state, the second member 4 (the body portion 2) is rotated and closed again. By setting the overlapped closed state, it is possible to reversely switch the exposed surface and the bottom surface of the overlapped portion 4 in the closed state. In the open state, the overlapped portion 4 rotates and rotates to a twist position in the middle of the 180-degree reverse rotation. In some cases, 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.

  Therefore, the locking portion 7 that rotates and rotates together with the rotation of the overlapping 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 used as 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. At the rotational axis position where the main body 2 and the overlapping portion 4 can be overlapped with each other so that the main body 2 and the overlapping portion 4 can be overlapped with each other, the overlapping portion 4 does not interfere with the restricting portion 7 and interferes with the restricting portion 8. In the open state, which is allowed to rotate by a predetermined angle from the closed state where they are overlapped with each other, the overlapping portion 4 is also allowed to rotate 180 degrees with respect to the main body portion 2 in the same manner. At the rotation position where the rotation is not performed, the movement of the locking portion 7 is obstructed by the restricting portion 8, and the overlapping portion 4 and The main body 2 can be superposed on the main body 2 without being twisted at the time of the closing rotation, such as the rotation of the rotation more than a predetermined angle is prevented from the rotation without rotation where the main body 2 can be superposed. In this case, the shape of the restricting portion 8 with respect to the locking portion 7 can be set so that the closed portion cannot be rotated and the end portion of the overlapping portion 4 does not contact the upper surface of the main body portion 2.

  When the wiring 24 for electrically connecting the circuit part provided in the main body part 2 and the circuit part provided in the superposition part 4 is routed around the hinge device, it can be opened and closed without being wound around the shaft part or attached to the outer surface of the shaft. The relay bending portion of the wiring 24 is stored in the storage space 26 provided in the restriction portion 8 serving as a relay position through the in-axis wiring path 25 provided in the undulating rotation shaft portion 9 of the portion HA, and the rotation rotation hinge portion HB. Wiring can be performed through the in-axis wiring path 25 provided on the rotation rotation shaft portion 16 of the rotating rotation shaft 16, the assembly can be easily manufactured with a simple configuration, and the wiring can be surely performed, and the wiring defect is hardly caused.

  In other words, the wiring can be simplified and with good durability, and even if the undulating rotation shaft portion 9 and the rotation rotation shaft portion 16 have a large diameter, they can be reduced in weight while being configured to allow the wiring to pass therethrough. It is possible to easily realize a concave portion and a deeply restricting portion for giving a large load, and further, for example, an operation of once pulling out the wiring 24 drawn out from the in-axis wiring path 25 to the storage space 26 provided in the restricting portion 8 becomes easy. If the drawer opening part 27 is provided and the shape of the edge part of the drawer opening part 27 is set to the regulation shape, the wiring is also connected to the regulation part position serving as a folding relay point of the wiring 24 passing through each orthogonal axis. Not only a storage part is provided, it is also easy to draw out the wiring that has passed through one axis and then pass the wiring through to the next axis, making it extremely easy to route the wiring. Hinge device and hinge The ability to realize an electronic device using a location.

  Further, if the undulation rotation shaft portion 9 and the restriction portion 8 are separate parts, that is, the predetermined portion of the undulation rotation shaft portion 9 is not integrally formed or processed into a predetermined shape, and the undulation rotation shaft is not formed. As a separate part from the portion 9, for example, the undulating rotation shaft portion 9 is inserted into the regulating portion forming member 8 </ b> A disposed between the leg portions 10 </ b> A of the shaft mounting portion 10, or the undulating rotation shaft portion 9 is inserted and connected from the side. The undulation rotation shaft portion 9 is connected to a restricting portion forming member 8A provided separately from the undulation rotation shaft portion 9 (which may be configured by assembling or arranging a plurality of parts). Thus, if the restricting portion 8 is provided on the undulating rotation shaft portion 9, for example, the undulating rotation shaft portion 9 that does not allow wiring to pass is thin, and the restricting portion forming member 8A can be designed to be large and compact as before. It is possible to achieve a structure that can be realized, and it is lightweight by using a hollow cylindrical member. The restricting portion forming member 8A can be easily formed with a sufficiently deep recess, and the contact surface (step surface) that prevents the rotation of the locking portion 7 can be easily formed. It is possible to easily realize an innovative hinge device and an electronic device using the hinge device that can be formed high, can reliably prevent the locking portion 7 from rotating, and have excellent durability. .

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.

  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. Rotation range is provided between the opening / closing rotation hinge part HA and the rotation rotation hinge part HB. In the rotation range (open state) that is opened and rotated by a predetermined angle or more from the closed state, the overlapping portion 4 can be rotated forward and backward by 180 degrees with respect to the main body portion 2, and the predetermined angle In a rotation position that does not reach the rotation position that is fully rotated to the open position, a rotation restriction mechanism that prevents rotation and prevents rotation beyond a predetermined angle, and holds and restricts a state where there is no twist to overlap each other. S is provided.

  In other words, in the present embodiment, opening rotation up to a predetermined angle is allowed, and the overlapping portion 4 is rotated 180 degrees relative to the main body portion 2 in the open state where the opening portion is opened and rotated more than a predetermined angle from the closed state. In the closed state, the exposed surface and the lower surface of the overlapping portion 4 can be reversed and switched, and the overlapping portion 4 rotates and rotates 180 degrees in the open state. When in the twisting position in the middle of rotation, the rotation restricting mechanism S is set so that it cannot be closed and rotated at least beyond an angle at which the end of the overlapping portion 4 comes into contact with the upper surface of the main body 2. It is composed.

  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 restricting 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. ) (A storage space 26 to be described later) is formed, and the edge of the recess is set to a restricting shape to form the restricting 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 through which the undulating rotation shaft portion 9 is inserted, and an upper hole portion (erection portion 10B) is provided with a shaft hole through which the rotation rotation shaft portion 16 is inserted.

  First, the opening / closing rotation hinge portion HA will be described. The opposing leg portion 10A of the U-shaped base portion 10 is rotatably connected to the left and right undulation rotation shaft portions 9, and the left and right leg portions of the base portion 10 are connected. A restricting portion forming member 8A constituting the restricting portion 8 between 10A is connected to the left and right undulating rotation shaft portions 9, and the shaft mounting portion is connected to the left and right undulating rotation shaft portions 9 and the central restricting portion forming member 8A. 10 is configured to be rotatable.

  More specifically, the undulating rotation shaft 9 on one side is arranged as a thin shaft rod on the side of the base portion 10 and is fixed to the mounting portion 5 attached to the first member 2 (main body portion 2). It is arranged inside and is fixed to the mounting portion 5 with a detent. In this cylindrical case 12, at least one of the cam portion 13 and the cam engagement portion 14 that engage with each other with the undulation rotation shaft portion 9 as an axis is relatively rotatable and slidable (in a non-rotating state). Decorated. That is, the cylindrical case 12 is connected to the mounting portion 5 in a non-rotating manner, and one end of the undulating rotation shaft portion 9 is also connected to the mounting portion 5 attached to the first member 2 in a non-rotating manner. Therefore, in the predetermined undulation rotation position, the cam portion 13 and the cam engagement portion 14 are positioned (cam locked) by relative rotation engagement between the cam engagement bias and the engagement bias by the spring 11. For example, in the closed state, the cam is engaged and closed, and in the open state, the cam is engaged (cam locked). It is configured to realize a free stop in which the rotational position is maintained.

  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, as will be described later, the undulating rotation shaft portion 9 on the opposite side is formed in a pipe shape (hollow cylindrical shape) and provided with an in-axis wiring path 25, and one end is fixed to the opposite attachment portion 5 to prevent rotation. The end is configured so as to be pivotably inserted into the shaft support hole 10C of the other leg 10A of the shaft mounting portion 10. And, as described later, the undulating rotation shaft portion 9 is not provided between the leg portions 10A of the shaft mounting portion 10, and a restricting portion forming member 8A constituting the restricting portion 8 is connected to the undulating rotation shaft portion 9 as will be described later. Yes.

  Then, the overlapping portion 4 is rotated on the base portion 10 that rotates with respect to the main body portion 2 (the cylindrical case 12, the undulating rotation shaft portion 9, the restricting portion forming member 8A) via the rotation rotation hinge portion HB. It is pivotably connected.

  The rotation rotation hinge portion HB provided with the rotation rotation shaft portion 16 is inserted through the rotation rotation shaft portion 16 into the shaft hole of the upper piece portion (the erection portion 10B) of the base portion 10 (the shaft mounting portion 10). An attachment portion 6 is provided at one end (upper end) of the rotation rotation shaft portion 16, and is connected to the overlapping portion 4 through the attachment portion 6, and the other end (lower end) is disposed in the shaft support hole 10C. The locking portion 7 is provided. Further, in this embodiment, the cam engaging portion 18 that is inserted into the rotation rotating shaft portion 16 (and the mounting portion 6) and is engaged with the cam portion 17 is inserted into the base portion 10. The upper piece portion (the erection portion 10B) is provided with irregularities, and 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. Yes.

  In addition, as will be described later, the rotation rotation shaft portion 16 is also formed in a pipe shape (hollow cylindrical shape) to provide an in-axis wiring path 25, and the locking portion 7 is formed at the peripheral edge of the lower end of the in-axis wiring path 25. is doing.

  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 stopper portion 20A that rotates together with the rotation rotation shaft portion 16 so as to be rotatable forward and reverse within this range without rotating about 180 degrees or more so as not to disturb the wiring is rotated. A stopper receiving portion 20B is provided on the installation portion 10B of the shaft mounting portion 10 so as to be fitted to the moving shaft portion 16 and to prevent the rotation turning shaft portion 16 from over-rotating in the forward / reverse 180 ° range or more. .

  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 restricting portion 8 has a concave shape (notch shape) for receiving it. The restricting shapes of the engaging portion 7 and the restricting portion 8 are not limited to this, and can be variously designed. For example, the engaging portion 7 has a long side portion and a short side portion with respect to the rotation surface of rotation. In this case, when the locking portion 7 is arranged at a position where it should be able to rotate and rotate, it has a concave shape (notch shape) having a sufficient diameter in all directions so as to allow this, and a predetermined rotation. In order to allow the undulation rotation in the moving direction, the concave portion shape (notch shape) that allows the revolving movement (undulation rotation) of the locking portion 7 in the rotation direction of the undulation rotation shaft portion 9 is formed. The concavity part (notch part) that is formed so as to be connected to the concave part space and allows the undulation rotation is wider than the short side part but wider than the long side part to prevent rotation. Narrow shape.

  As another example, the locking portion 7 has a concave shape with the lower surface escaping the undulating rotation shaft portion 9 so that the undulating rotation shaft portion 9 can be moved and moved in the undulation rotation direction during the undulation rotation. In this case, the rotational rotation is obstructed and the rotational rotation is prevented. However, at the position where the rotation is sufficiently raised and lowered, the rotational rotation is not prevented by the wide recesses (notches). Can be designed.

  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, since the rotation of the closed portion in the twisted state is also prevented, and the rotation of the rotating portion in the twisted direction in the middle of the closed rotation in the correct direction is also prevented, the end corner portion of the overlapping portion 4 is prevented from rotating. 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 setting the edge of the restriction shape of the restriction portion 8 to be chamfered, when the overlapping portion 4 is closed and rotated at a slightly twisted rotation position, the overlapping portion is automatically formed along the upper end shape of the restriction portion 8. 4 can be configured to rotate and rotate in the correct orientation, and can be overlapped. Also, as described above, it can be rotated to any open range, and if it is twisted, it can not be rotated. In addition, it can be finely adjusted.

  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.

  More specifically, in this embodiment, the shaft mounting portion 10 is provided on the undulating rotation shaft portion 9 of the opening / closing rotation hinge portion HA which is rotatably provided. The portion 8 has a configuration in which an outer surface shape is set to a restriction shape that restricts the rotation of the locking portion 7, and the undulation rotation shaft portion 9 on the one side of the opening / closing rotation hinge portion HA and the rotation rotation.

An in-axis wiring path 25 is provided, and a storage space 26 for storing the relay bent portion of the wiring 24 inserted and disposed in each of the in-axis wiring paths 25 is provided in the restriction portion forming member 8A constituting the restriction portion 8; The outer shape of the storage space 26 of the restricting portion 8 is set to the restricting shape, and the rotation restricting mechanism S is Forms.

  That is, the restricting portion 8 does not have a configuration in which the outer surface of the undulating rotation shaft portion 9 is formed in a predetermined shape and is integrally formed with the undulating rotation shaft portion 9, but a restricting portion forming member in which the outer surface portion is formed in a predetermined shape. The undulation rotation shaft portion 9 is connected to 8A, and the restricting portion 8 is provided on the undulation rotation shaft portion 9 as a separate part. The restriction portion forming member 8A is in communication with the intra-axis wiring paths 25. The restricting portion forming member 8A employs a cylindrical part to form a communication hole and a notch opening portion (drawer opening portion 27) in the hollow portion. As a configuration in which the storage space 26 is provided in a shape communicating with the wiring path 25, the undulating rotation shaft portion 9 is inserted and connected through the communication hole of the restricting portion forming member 8A, and the end exit is stored in the storage space. 26 to communicate with the in-axis wiring path 25 and the storage space 26. And the end outlet of the rotation rotation shaft portion 16 faces the drawer opening portion 27 of the storage space 26 so that the in-axis wiring path 25 provided in the rotation rotation shaft portion 16 and the storage space 26 are formed. It is formed in a communication state.

  Specifically, the storage space 26 of the restricting portion 8 formed so as to communicate with the in-axis wiring paths 25 temporarily pulls the wiring 24 drawn out from the in-axis wiring paths 25 to the outside of the storage space 26. A drawer opening 27 that facilitates operation is provided, and the shape of the edge of the drawer opening 27 is set to the restriction shape. Then, the locking portion 7 is positioned on the upper part of the drawer opening portion 27 and the end exit of the rotation rotation shaft portion 16 is faced, and the drawer opening portion 27 opens a communication hole on the side of the open storage space 26. The undulating rotation shaft portion 9 is inserted and communicated, and similarly inserted into the mounting holes of the mounting portions 5 and 6, and relays the storage space 26 of the restricting portion forming member 8 </ b> A from each mounting portion 5 to the mounting portion 6. The in-axis wiring path 25 communicates in an L shape.

  That is, in this embodiment, the restricting portion forming member 8A is constituted by a cut-out cylindrical part, and the restricting portion forming member 8A having the hollow portion as the storage space 26 and the opening portion by the notch portion as the drawer opening portion 27. The undulating rotation shaft portion 9 is inserted using the side communication hole as an attachment hole, and the rotation rotation shaft portion 16 faces the drawer opening portion 27 to form a wiring path, and in particular, the drawer opening portion 27 is largely opened. Thus, when wiring, the wiring 24 that has passed through the in-axis wiring path 25 is once pulled out, or is pushed into the next in-axis wiring path 25, and can be easily pulled out. And the recessed part and opening part which notched the peripheral shape of the drawer | drawing open part 27 of this storage space 26 as the regulation shape are made into allowance space.
