Examples

The embodiment of the present invention will be described in detail with reference to the attached drawings. In Embodiment 1, an automatic standing opening and closing device is assembled into a hinge device (refer to FIG. 2) that connects the first frame body and the second frame body in a freely rotatable manner. The automatic standing opening and closing device and the second frame The movement of the body from the closed position to the opening device is linked to move the standing member from the storage position to the action position. Therefore, it is not necessary to provide a mechanism that supports the standing member and a mechanism that links the standing member and the operation of the second frame on the outside of the hinge device. The mechanism that rotates the second assembly member and the first assembly member in the same direction as the first assembly member and rotates by a larger angle can be miniaturized and stored around the hinge shaft of the hinge device.

(Terminal machine)

Figure 1 is a perspective view of a terminal machine. Figure 2 is the closed position and open position of the second frame Set the explanatory diagram. FIG. 3 is an explanatory diagram of the storage position and the action position of the standing member. In FIG. 3, (a) is a supporting position, and (b) is a storage position. As shown in FIG. 1, the terminal device 1 is a tablet computer attached to a computer body, a so-called 2 in 1 type laptop computer in which the keyboard unit of the second housing is assembled in a detachable manner. The second frame 3 is a support plate 6a of the second frame assembly member 6 provided with a magnet 6m on four legs, and is assembled in a detachable manner by the magnetic force of the magnet 6m.

The second frame 3 is a so-called tablet computer in which a touch panel is provided on the image display unit 3d, and a touch input can be performed by directly touching the image display unit 3d with a finger. The first frame 2 will transmit the signal to the second frame 3 by short-range wireless communication according to the input signals arranged on the operation surface 2a of the keyboard unit or the operation signal of the keyboard. The second frame 3 can also be removed and carried by the second frame assembly member to resist the magnetic force of 6m of the magnet, and it can be used alone as a tablet computer.

In the terminal device 1, the first housing 2 placed on the mounting surface SM with the operation surface 2a upward is provided with the second housing 3 of the image display unit 3d so as to be able to be placed at an approximately horizontal closed position The vertical opening position can be opened and closed freely, using a pair of hinge devices 10 and 10 to connect. The hinge device 10, which is an example of an automatic standing opening and closing device, connects the second frame 3 to the first frame 2 in such a manner that they can be opened and closed and can be stopped at any opening angle. The second frame assembly member 6 can stop the rotation of the second frame 3 to the first frame 2 at an arbitrary angle in the range of 0 degrees to 135 degrees.

As shown in FIG. 2, the rehearsal device 10 connects the first frame 2, the second frame 3, and the standing member 7. The first housing 2 is placed on the placement surface SM with the operation surface 2a facing upward. The second housing 3 includes a video display unit 3d. The standing member 7 is tied behind the first frame 2 and is grounded on the placement surface SM. The second frame 3 is in the closed position P0 when it overlaps with the second frame. At this time, the opening angle θ1 of the hinge device 10 = 0 degrees. The second frame 3 is the opening position P1 within the range of the opening angle θ2=85 degrees of the hinge device 10 to the opening angle θ3=135 degrees. The hinge device 10 has a structure described later, so that the limit of the rotation angle of the second frame 3 is 135 degrees.

In such a terminal device 1, since the second frame 3 is heavier than the first frame 2, the center of gravity will move to the rear of the first frame when the second frame 3 is in the open position, making the overall Dumped from the rear. Alternatively, when the second frame 3 is in the open position P1 and an input operation is performed on the image display unit 3d by touch, the second frame 3 moves backward to make the input operation incorrect.

Therefore, the terminal device 1 is provided with a standing member 7 on the first frame 2, The supporting portion 7a of the tool 7 is grounded on the mounting surface SM behind the second frame 3, and supports the center of gravity of the second frame 3 from the rear. The hinge device 10 moves the standing member 7 in conjunction with the rotation of the second frame 3 with respect to the first frame 2, and stably holds the first frame 2 and the second frame 3. As a result, when the second frame 3 is located at the open position P1, it is difficult for the entire body to fall backward. Alternatively, when the second frame 3 is in the open position and an input operation is performed on the image display portion 3d by touch, the second frame 3 does not move backward and can perform a correct input operation.

The standing member 7 can rotate the first frame 2 by the hinge device 10. The standing member 7 is linked with the rotation of the second frame 3 by the hinge device 10, and is rotated by about 180 degrees from the storage position Q0 of the storage posture overlapping the second frame 3 at the closed position P0, and moved to The action position Q1 of the action posture of the placement surface SM is grounded behind the second frame 3.

The hinge device 10 gives the standing member 7 a larger rotation angle than the second frame 3 by the two structures described below. The hinge device 10 moves the standing member 7 from the storage position Q0 to the action position Q1 by about 180 degrees while the second frame 3 is opened by about 90 degrees from the opening angle θ0 to θ1. The hinge device 10 moves the standing member 7 from the action position Q1 to the storage position Q0 by approximately 180 degrees during the closing of the second frame 3 from the opening angle θ3 to the angle of approximately 90 degrees.

As shown in FIG. 3(a), at the open position P1, the hinge device 10 causes the second frame assembly member 6 to stand approximately 90 degrees to the operation surface 2a of the first frame 2, so that the standing member 7 is in the second frame The body 3 is grounded to the mounting surface SM on the rear side. As shown in FIG. 3(b), at the closed position P0, the hinge device 10 lays both the second frame assembly member 6 and the standing member 7 so as to lie parallel to the operation surface 2a of the first frame .

The hinge device 10 fixes the end of the hinge shaft 11 to the assembly portion 2b of the first housing 2. The second frame assembly member 6 is fixed to an assembly portion 6b that rotates around the hinge shaft 11, that is, the first assembly member 31 of the hinge device 10, using fixing screws (not shown). The standing member 7 is fixed to the assembly portion 7b (the second assembly member 32 of the hinge device 10) that rotates around the hinge shaft 11 using fixing screws (not shown). The hinge device 10 has the left and right standing members 7 and the central second frame assembly member 6 in common, and is disposed on the left and right of the terminal device 1 respectively. This is because the rotation control force caused by the hinge device 10 for the standing member 7 is well balanced between left and right.

(Hinge device)

FIG. 4 is an explanatory view of the assembled state of the hinge device. Figure 5 is the exploded oblique of the hinge device view. In FIG. 4, (a) is an appearance, and (b) is an internal structure. As shown in FIG. 4(a), the first assembling member 31 and the second assembling member 32 of the hinge device 10 can rotate around the hinge shaft 11 which is arranged to penetrate through the center, and the hinge shaft 11 can be fixed to the first frame 2. The first assembly member 31, which is an example of the input member, can be fixed to the second frame 3, and freely rotatable on the axis of the hinge shaft 11. The second assembly member 32, which is an example of the output member, can be fixed to the standing member 7, and can freely rotate on the axis of the hinge shaft 11.

As shown in FIG. 4(b), the hinge shaft 11 is inserted, and a rotation range restricting member 12, a rotating member 13, a friction torque generating member 14, a friction plate 15, a cam member 16, a rotation transmitting member 17, and an input member 18 are assembled , Output member 19, trend support member 22, trend member 21, trend reference member 23, discharge member 20.

The rotation restricting protrusions 13e, 14e, 15e, 18e are constrained by the first assembly member 31, so the first assembly of the rotation member 13, the friction torque generating member 14, the friction plate 15, and the input member 18 with the hinge shaft 11 The member 31 rotates integrally around the hinge shaft 11. On the other hand, since the rotation restricting protrusion 19e is restricted by the second assembly member 32, the output member 19 rotates around the hinge shaft 11 integrally with the second assembly member 32.

The rotation transmitting member 17 can freely move the output member 19 in the axial direction in a state where the rotation of the output member 19 is restricted. The rotation transmitting member 17 makes the other end of the axial direction abut against the cam member 16 in a state where the tendency member 21 presses one end of the axial direction. Therefore, the rotation transmitting member 17 is guided by the cam member 16 as the rotation is moved in the axial direction.

As shown in FIG. 5, the first assembly member 31 is formed with a circular hole-shaped storage hole 31 a of the storage mechanism portion 10P and a restriction groove 31 m that restricts the partial rotation of the mechanism portion 10P. Since the rotating member 13, the friction torque generating member 14, the friction plate 15, the input member 18, and the rotation restricting protrusions 13e, 14e, 15e, and 18e are located in the restricting groove 31m, the rotation of the first assembly member 31 can be restricted.

On the other hand, in the second assembly member 32, a round hole-shaped storage hole 32a with a bottom portion of the storage mechanism portion 10Q and a restriction groove 32m that restricts partial rotation of the mechanism portion 10Q are formed. Since the output member 19 has the rotation restricting protrusion 19e located in the restricting groove 32m, the rotation of the second assembly member 32 can be restricted.

The input member 18 can be positioned at a fixed position in the axial direction of the hinge device 10 by overlapping the pin hole 31b of the first assembly member 31 and the pin hole 18f of the input member 18 and inserting the fixing pin 26, Instead, the rotation of the first assembly member 31 is fixed.

The output member 19 can be positioned at a fixed position in the axial direction of the hinge device 10 by superimposing the pin hole 32b of the second assembly member 32 and the pin hole 19f of the output member 19 and inserting the fixing pin 27 to fix the second assembly Rotation of member 32.

A flat assembly portion 11a is formed at the end of the hinge shaft 11, and an assembly hole 11b for fixing is formed at the assembly portion 11a. The hinge shaft 11 and the first frame 2 overlap the assembly hole 11b formed in the assembly portion 11a and the assembly hole 2c formed in the assembly portion 2b of the first frame 2, and insert the fixing pin 11h by inserting the fixing pin The end is riveted before 11h and can be fixed integrally.

As shown in FIG. 4(b), the cam member 16 and the trend reference member 23 determine the axial distance between the two ends, and a pair of the trend support member 22, the trend member 21, and the rotation transmission member 17 are held to compress the trend Member 21. The tendency member 21 tends to rotate the transmission member 17 toward the cam member 16. The tendency member 21 makes the rotation transmission member 17 tend to be in the axial direction, and is pressed against the cam surface of the cam member 16. As the rotation transmission member 17 rotates, the rotating rotation transmission member 17 is guided by the stopped cam member and moves in the axial direction.

(Rotation range limiter)

Fig. 6 is an explanatory diagram of a rotation range restricting portion. As shown in FIG. 2, in the terminal device 1, the rotation range of the second frame 3 is limited to the range of the opening angles θ0 to θ3.

As shown in FIG. 5, in the rotation range restricting portion 33, the rotation range restricting member 12 restricts the rotation range of the rotation member 13. The rotation range restricting member 12 engages the upper and lower engaging convex portions 12c and 12d with the engaging convex portions 11f and 11g of the hinge shaft, respectively, so that even if the first assembly member 31 rotates, the hinge shaft stops. On the other hand, the rotation member 13 engages the rotation restriction protrusion 13e in the restriction groove 31m of the first assembly member 31, so if the first assembly member 31 rotates, the rotation member also rotates integrally with the first assembly member 31 .

As shown in FIG. 6, the rotation range restricting member 12 has restriction protrusions 12e on the opposite sides of the engaging protrusions 12c and 12d, and restriction surfaces 12f and 12g are formed on the restriction protrusions 12e. On the other hand, on the surface of the rotating member 13 that faces the limiting convex portion 12e, a limiting convex portion 13g is formed, which engages with the limiting convex portion 12e as the rotating member 13 rotates. Therefore, the range in which the rotation member 13 can rotate the rotation range limiting member 12, that is, the range in which the first assembly member 31 can rotate the hinge shaft 11, is the limiting surface 13 i The range from the angle of contact with the restriction surface 12f to the angle of the restriction surface 13j with the restriction surface 12g.

(Output section)

7 is an explanatory diagram of the configuration of the output unit. As shown in FIG. 7, the output unit 34 transmits the rotation taken out by the rotation transmission member 17 to the output member 19. The output member 19 is formed with a pin hole 19f penetrating in the thickness direction of the rotation restricting protrusion 19e.

As described above, the outer peripheral portion 17b of the rotation transmitting member 17 and the outer peripheral portion 19b of the output member 19 shown in FIG. 5 are rotatably held by the storage holes 31a of the first assembly member 31. The output member 19 restricts the rotation of the second assembly member 32 by the rotation restricting protrusion 19e, so it rotates integrally with the second assembly member 32. On the other hand, since the rotation transmission member 17 is held by the corner hole 19a of the output member 19, the corner column portion 17h rotates integrally with the output member 19. However, the rotation transmitting member 17 restricts the rotation of the output member 19, but can freely move in the axial direction. Therefore, the rotation transmitted from the input member 18 and the cam member 16 to the rotation transmission member 17 is transmitted to the second assembly member 32 through the output member 19, but the axial movement transmitted from the cam member 16 to the rotation transmission member 17 does not Will interfere with the output member 19.

(Standing member rotation control means)

FIG. 8 is an explanatory diagram of the structure of the rotation transmission part. 9 is an explanatory diagram of the cam curve of the cam member. 10 is an explanatory diagram of the rotation range of the rotation transmission member in the open position of the hinge device. In FIG. 10, (a) is 90 degrees and (b) is 135 degrees.

As shown in FIG. 4(b), the input member 18 restricts rotation and axial movement of the first assembly member 31. The rotation transmission member 17 can move in the axial direction in a state where the rotation of the second assembly member 32 is restricted, and is engaged with the input member 18 to transmit the rotation of the second transmission member 32. The outer peripheral portion 17b of the rotation transmitting member 17, the outer peripheral portion 18b of the input member 18, and the outer peripheral portion 16b of the cam member 16 are held in the storage hole 31a of the first assembly member 31. In the cam member 16, the central flat hole 16a is constrained by the hinge shaft 11, which restricts the rotation of the hinge shaft 11. The input member 18 holds a cylindrical portion 17k of the rotation transmission member 17 in a freely rotatable circular hole 18a in the center.

As shown in FIG. 5, by holding the flat portion 11 d of the hinge shaft 11 with the flat hole 16 a in the center, the cam member 16 can restrict the rotation of the hinge shaft 11. The cam member 16 is pressed toward the rotation transmitting member 17 by the tendency force of the tendency member 21, and abuts on the end portion 11j of the flat portion 11d of the hinge shaft 11, It is positioned at a predetermined position in the axial direction of the hinge shaft 11. The cam member 16 is provided with a cam surface with a phase difference of 180 degrees on the inside and outside in the diameter direction so that the cam member 16 does not incline.

The rotation transmitting member 17 is able to rotate freely around the hinge shaft 11 because the flat portion 11d of the hinge shaft 11 is held in the circular hole 17a at the center. The trend reference member 23 is a so-called E ring assembled in the annular groove 11m of the hinge shaft 11, and the trend reference member 21 determines the trend reference position of the rotation transmission member 17. The trend support member 22 is inserted into the flat portion 11d of the hinge shaft 11 at the center flat hole 22a to restrict the rotation, so that the end surface of the compression spring trend member 21 is in a compressed state and is positioned perpendicular to the axis direction.

The output member 19 has the corner post portion 17h of the rotation transmission member 17 inserted into the central corner hole 19a, so that the rotation transmission member 17 can be moved in the axial direction with the rotation of the rotation transmission member 17 restricted. Therefore, even if the rotation transmission member 17 guided by the cam member 16 moves in the axial direction, the output member 19 outputs the rotation of the rotation transmission member 17 to the second assembly member at a fixed position in the axial direction.

As shown in FIG. 8, the standing member rotation control means 35 transmits the rotation from the input member 18 to the output member 19 through the cam member 16. The standing member rotation control means 35 inputs a rotation of less than 90 degrees to the input member 18 and outputs a rotation of 180 degrees or more to the rotation transmission member 17. The rotation of the input member 18 by about 90 degrees (specifically, 85 degrees) is transmitted to the rotation transmitting member 17 through the cam member 16, and the rotation transmitting member 17 is rotated by about 180 degrees (specifically, 183 degrees).

The cam member 16 is in contact with the rotation transmission member 17 in a state of restricting the rotation of the hinge shaft 11 and the movement in the axial direction, and moves the rotation transmission member 17 in the axial direction as the rotation transmission member 17 rotates. When the rotation transmission member 17 guided by the cam member 16 rotates, the rotation transmission member 17 is guided by the cam surfaces 16c and 16d of the cam member 16 and moves in the axial direction, causing the tendency member 21 to expand and contract.

CAM员16. As described above, the outer cam surface 16c and the inner cam surface 16d arranged concentrically are included. The rotation transmission member 17 includes a protrusion 17c guided by the outer cam surface 16c and a protrusion 17d guided by the inner cam surface 16d. The cam surfaces 16c and 16d form a range of approximately 180 degrees corresponding to the open position of the storage position Q0 to the action position Q1 shown in FIG. 2.

The outer cam surface 16c includes: a valley bottom corresponding to the axial direction of the storage position Q0 The portion 16e, the valley bottom 16f corresponding to the axial direction of the action position Q1, and the mountain top 16g corresponding to the intermediate position between the storage position Q0 and the action position Q1. The valley bottoms 16e and 16f hold the rotation transmission member 17 at the storage position Q0 and the action position Q1 of the standing member 7, respectively. The mountain top 16g reverses the movement of the rotation transmission member 17 in the axial direction between the storage position Q0 and the acting position Q1 of the standing member 7. On the other hand, the inner cam surface 16d includes a valley bottom 16i corresponding to the storage position Q0, a valley bottom 16j corresponding to the operation position Q1, and a mountain top 16k corresponding to an intermediate position between the storage position Q0 and the operation position Q1.

Here, for convenience of explanation, in the following, the rotation angle of the rotation transmission member 17 interlocked with the standing member 7 at the storage position Q0 is similarly referred to as the storage position Q0, and the rotation transmission member 17 when the standing member 7 is at the action position Q1 The rotation angle of is likewise called the action position Q1. Also, the angular position of the input member 18 interlocked with the second frame 3 at the closed position P0 is similarly referred to as the closed position P0, and the angular position of the input member 18 at the open position P1, The same is called the open position P0.

The explanation is continued according to such a definition. When the rotation transmission member 17 is at the storage position Q0, the tendency member 21 tends to be engaged, the protrusion 17d of the rotation transmission member 17 is engaged with the valley bottom 16j of the cam member 16, and the protrusion 17c of the rotation transmission member 17 is engaged with the cam member 16f at the bottom of the Valley of 16. Thereby, as shown in FIG. 2, when the standing member 7 is at the storage position Q0, even if the frame 2 and the frame 3 are held in the reverse direction, the tendency force of the tendency member 21 can be held on the card respectively. In the closed state, the frame 3 and the standing member 7 will not open downward from the frame 2.

Also, when the rotation transmission member 17 is at the action position Q1, the tendency member 21 tends to be, the protrusion 17d of the rotation transmission member 17 is engaged with the valley bottom 16i of the cam member 16, and the protrusion 17c of the rotation transmission member 17 is engaged with The bottom 16e of the valley of the cam member 16. By this, as shown in FIG. 2, when the standing member 7 is at the action position Q1, even if the image surface 3a of the frame 3 is pushed back, the opening angle of the standing member 7 is maintained due to the tendency force of the tendency member 21, the terminal The machine 1 will not tilt or fall backward.

When the rotation transmission member 17 is at the intermediate position Q2 of the storage position Q0 and the action position Q1, the protrusion 17d of the rotation transmission member 17 is located at the top 16k of the cam member 16, and the protrusion 17d of the rotation transmission member 17 is located at the top of the cam member 16.部16g. This state is unstable, rotation transmission If the member 17 loses the support of the rotational position, the cam surfaces 16c, 16d will naturally fall off and be positioned at the storage position Q0 or the action position Q1. Therefore, if the rotation transmission member 17 is driven by the input member 18, the valley bottom 16e rotates against the tendency member 21, so that the protrusion 17d exceeds the mountain top 16g, the rotation transmission member 17 is rotated by the tendency member 21, and the protrusion 17d remains at the bottom of the valley 16f.

The input member 18 is formed with a pair of engaging portions 18c and 18d, which hold the engaged portion 17m of the rotation transmission member 17 protruding in the axial direction, and face the rotation direction. When the engaging portion 18c moves the rotation transmitting member 17 from the storage position Q0 to the acting position Q1, it abuts on the engaged portion 17m and transmits the rotation to the rotating transmitting member 17. When the rotation transmission member 17 is moved from the action position Q1 to the storage position Q0, the engagement portion 18d abuts the engaged portion 17m and transmits rotation to the rotation transmission member 17.

As shown in FIG. 9, the cam surfaces 16c and 16d of the cam member 16 are attached to the rotation transmission member 17 from the storage position Q0 to the center position Q2 toward the action position Q1 by about 180 degrees, so that the rotation transmission member 17 reciprocates in the axial direction Instead, the trending member 21 expands and contracts.

When the engaging portion 18c of the input member 18 moves the rotation transmission member 17 from the storage position Q0 to the action position Q1, the rotation transmission member 17 rotates from the storage position Q0 to an angle slightly exceeding the intermediate position Q2. During this process, the trending member 21 is compressed to accumulate the trending force. Then, from exceeding the intermediate position Q2 to the acting position Q1, the tendency force accumulated by the tendency member 21 tends to cause the rotation transmission member 17 to slide off the cam surfaces 16c, 16d.

When the engaging portion 18d of the input member 18 moves the rotation transmission member 17 from the storage position Q0 to the action position Q1, the rotation transmission member 17 rotates from the storage position Q0 to an angle slightly exceeding the intermediate position Q2. During this process, the trending member 21 is compressed to accumulate the trending force. Then, from exceeding the intermediate position Q2 to the acting position Q1, the tendency force accumulated by the tendency member 21 tends to cause the rotation transmission member 17 to slide off the cam surfaces 16c, 16d.

As shown in FIG. 10(a), at the 90-degree opening position P1 of the input member 18, the rotation transmission member 17 is positioned at the action position Q1. By the rotation transmitting member 17 in which the tendency member 21 tends to the axial direction, the protrusion 17c is held by the valley bottom 16e of the cam member 16. Thereby, as shown in FIG. 2, even if the image surface 3 a of the frame body 3 is pushed backward, since the protrusion 17 c of the rotation transmission member 17 continues to be held at the bottom 16 e of the valley of the cam member 16, the terminal device 1 will not tilt backward , Upset.

In this state, as shown in FIG. 10(b), the input member 18 is rotated to the open position P1 of 135 degrees. In other words, the cam member 16 can rotate the input member 18 from 90 degrees to 135 degrees without the engaging portions 18c and 18d of the input member 18 contacting the engaged portion 17m of the rotation transmitting member 17. In addition, the rotation of 135 degrees or more is restricted by the above-mentioned rotation range restricting portion 33.

In this way, in the hinge device 10, the rotation transmission member 17 is manually rotated about half of the stroke between the storage position Q0 and the acting position Q1, and the remaining half of the stroke is caused by the restoring force of the tendency member 21 to make the rotation transmission member 17 automatic rotation. Therefore, as shown in FIG. 2, the rotation of the second frame 3 at approximately 90 degrees can rotate the standing member 7 at approximately 180 degrees.

(Inclined surface)

FIG. 11 is an explanatory diagram of the process of moving the standing member to the storage position. FIG. 12 is an explanatory diagram of the process of moving the standing member to the storage position. In FIG. 11, (a) is 85 degrees and (b) is 75 degrees. In FIG. 12, (a) is 55 degrees, (b) is 45 degrees, and (c) is 35 degrees.

As shown in FIG. 2, using the terminal device 1, if the user opens the second frame 3 to the first frame 2 from the closed position P0 to the open position P1, the standing member 7 at the storage position Q0 will be hinged The shaft 11 rotates toward the action position Q1 as a center. At this time, as shown in FIG. 4( b ), the input member 18 rotates as the first assembly member 31 rotates, and the rotation transmission member 17 engaged with the input member 18 rotates the cam member 16. As the rotation transmission member 17 rotates, the cam member resists the tendency force of the tendency member 21 and squeezes the rotation transmission member 17 upward in the axis direction. At this time, the vertical surface 18i and the inclined surface 18j of the input member 18 adjust the torque transmitted from the input member 18 to the rotation transmission member 17 according to the rotation position of the rotation transmission member 17.

As shown in FIG. 8, the engaging portion 18c of the input member 18 is formed with a vertical surface 18i and an inclined surface 18j in the axial direction. The vertical surface 18i and the inclined surface 18j are the opposing surface, the engaging surface, and the contact surface with respect to the engaged portion 17m of the rotation transmission member 17. When the input member 18 rotates at a speed v, the vertical surface 18i presses the engaged portion 17m in the direction of rotation, causing the rotation transmission member 17 to rotate at a speed greater than the speed v.

Since the protrusion 17d of the rotation transmission member 17 is held at the storage position Q0 of the valley bottom 16f, the end surface 17n of the rotation transmission member 17 abuts on the vertical surface 18i of the input member 18 and starts to rotate with a large torque. After that, if the rotation transmitting member 17 is guided by the cam member 16 in the axial direction When moving, the end surface 17n of the rotation transmission member 17 abuts on the inclined surface 18j of the input member 18, and rapidly rotates with a small torque.

Therefore, by rotating the input member 18, the protrusion 17d of the rotation transmission member 17 can be easily detached from the valley bottom 16f. On the other hand, by the rotation of the input member 18 less than 90 degrees (85 degrees), the rotation transmission member 17 can be rotated more than 90 degrees (183 degrees).

On the other hand, a vertical surface 17i and an inclined surface 17j in the axial direction are formed in the engaged portion 17m of the rotation transmission member 17. The vertical surface 17i and the inclined surface 17j are opposed surfaces, engaging surfaces, and abutting surfaces with respect to the engaging portion 17d of the input member 18.

As shown in FIG. 11(a), at the action position Q1 of the rotation transmission member 17, the protrusion 17c is held by the valley bottom 16e. The valley bottom 16e is formed in a circular arc shape in order to increase the resistance of the standing member 7 when the second frame 3 is pushed rearward, conforming to the shape of the front end of the protrusion 17c. Therefore, a large torque is required to disengage the protrusion 17d from the valley bottom 16e.

As described above at the open position P1 of 135 degrees to 90 degrees, the input member 18 is idling around the rotation transmitting member 17. However, in the process toward the closed position, the input member 18 starts from the 85-degree open position P1, and the engaging portion 18d of the input member 18 abuts against the engaged portion 17m of the rotation transmitting member 17 and starts to squeeze. The input member 18 is between 85 degrees and 75 degrees, and the engaging portion 18 d of the input member 18 abuts on the vertical surface 17 i of the rotation transmission member 17 to transmit a large torque. With this, as shown in FIG. 11( b ), the protrusion 17 d of the rotation transmission member 17 is easily detached from the bottom of the valley of the cam member 16.

After that, if the rotation transmission member 17 guided by the cam member 16 squeezes upward in the axial direction, as shown in FIG. 12(a), the engaging portion 18d of the input member 18 becomes an inclined surface 17j that squeezes the rotation transmission member 17 . Until the input member 18 changes from 75 degrees to 33 degrees, the cam member 16 continues to squeeze the rotation transmission member 17 upwards. At this time, the engaging portion 18d of the input member 18 will increase the rotation speed of the rotation transmission member 17 plus The inclined surface 17j moving along the axis of the rotation transmission member 17 rotates at a forward speed. As the speed increases, the torque transmitted from the input member 18 to the rotation transmission member 17 decreases. The inclination of the inclined surface 17j is set to rotate the rotation transmitting member 17 at a rotation angle twice that of the input member 18.

As shown in FIG. 12(b), if the input member 18 rotates to 33 degrees, the protrusion 17c of the rotation transmission member 17 will reach the mountain top 16g of the cam member 16. At this time, the axis of the rotation transmitting member 17 The movement in the direction is stopped, and the rotation speed of the input member 18 and the rotation transmission member 17 are equal at an instant. However, after that, the protrusion 17c of the rotation transmission member 17 will exceed the mountain top 16g of the cam member 16, and as shown in FIG. 12(c), it starts to slide down the slope from the mountain top 16g to the valley bottom 16f.

Therefore, the rotation transmission member 17 will be the first to rotate, and the inclined surface 17j of the rotation transmission member 17 will be separated by the engaging portion 18d of the input member 18, accompanied by the rotation of the input member 18 from 33 degrees to 0 degrees, continuing in a manner to pursue it Turn.

(Unloading member)

13(a), (b), and (c) are explanatory views of the structure of the discharge member 20. FIG. As shown in FIG. 4, the discharge member 20, which is an example of the viscous moment generating member, is arranged on the axis of the hinge shaft 11, and resists the rotation of the output member 19 to the hinge shaft 11 and exerts a viscous resistance on the output member 19.

The outer peripheral portion 25b of the bearing portion 25 of the unloading member 20 is housed in a round hole-shaped housing hole 32 of the second assembly member 32 with a bottom portion. The rotation restricting protrusion 25e of the bearing portion 25 housed in the housing hole 32 is located in the restriction groove 32m together with the rotation restricting protrusion 19e of the output member 19, so the bearing portion 25 is integrated with the output member 19 by the second assembly member 32 Turn. On the other hand, since the flat hole 22a in the center of the shaft portion 24 is inserted into the flat end portion 11i of the hinge shaft 11, the rotation of the hinge shaft 11 by the shaft portion 24 is restricted.

As shown in FIG. 13( a ), the discharge member 20 is attached to the inner side of the bearing portion 25 to rotatably hold the shaft portion 24. The space between the inner peripheral surface 25a of the bearing portion 25 shown in FIG. 13 and the outer peripheral surface 24b of the shaft portion 24 shown in FIG. 13(c) is filled with high-viscosity oil (or semi-solid viscous material). On the outer peripheral surface 24b of the shaft portion 24, in order to increase the oil stirring effect, a stirring portion 24c in which protrusions and recesses are alternately arranged is formed. At the bottom of the bearing portion 25, a holding portion 25c capable of holding the shaft portion 24 in a freely rotatable manner is formed, and a uniform oil layer holding the concentric state of the bearing portion 25 and the shaft portion 24 is formed on the outer periphery of the shaft portion 24. On the outlet side, a seal 25s is provided between the bearing portion 25 and the shaft portion 24 to prevent oil from leaking to the outside.

As shown in FIG. 4(b), as the output member 19 rotates in the direction C of the action position Q1 or the direction D of the storage position Q0, the discharge member 20 relatively rotates between the bearing portion 25 and the shaft portion 24 . The discharge member 20 generates and rotates in a manner to resist the rotation of the bearing portion 25 and the shaft portion 24 The viscous resistance is proportional to the moving speed. The discharge member 20 optimizes the rotation position of the output member 19 with respect to the hinge shaft 11. In the range where the input member 18 does not support the rotation transmission member 17, the rotation transmission member 17 is slowly rotated to release the tendency force accumulated in the tendency member 21, whereby the rotation transmission member 17 is surely engaged with the cam member 16. In addition, when a sudden force is applied to the second housing 3, the discharge member 20 locks the rotation of the output member 19 to the hinge shaft, and resists the force of the standing member 7 toward the storage position Q0.

Moreover, the movement of the tendency supporting member 22 driven by the tendency member 21 is restricted by the tendency reference member 23 which is engaged with the annular groove 11m of the hinge shaft 11, so the tendency force of the tendency member 21 does not affect the discharge member 20 has an impact.

(Friction torque generating member)

As shown in FIG. 4, the friction torque generating member 14 is arranged on the axis of the hinge shaft 11. The friction torque generating member 14 resists the rotation of the input member 18 on the hinge shaft 11 and acts on the input member 18 with frictional resistance, whereby the input member 18 can be kept stopped on the hinge shaft 11. Thereby, the friction torque generating member 14 can keep the second frame 3 stopped at an arbitrary angular position between the closed position P0 and the open position P1.

The outer peripheral portion 14b of the friction torque generating member 14 is housed in the housing hole 31a of the first assembly member 31. The rotation restricting protrusion 14e of the friction torque generating member 14 housed in the receiving hole 31a is located in the restricting groove 31m together with the rotation restricting protrusion 18e of the input member 18, so the friction torque generating member 14 is combined with the first assembly member 31 The input member 18 rotates integrally. On the other hand, the diameter of the concave-convex hole 14a in the center of the friction torque generating member 14 is formed to be smaller than the round shaft portion 11c of the hinge shaft 11. The round shaft portion 11c of the hinge shaft 11 is inserted by squeezing the concave-convex hole 14a in the center of the friction torque generating member 14, and the rotation of the input member 18 is between the relative rotating friction torque generating member 14 and the hinge shaft 11 , Acting frictional resistance. Therefore, as shown in FIG. 2, the second frame 3 can be stopped at an arbitrary angular position between the closed position P0 and the open position P1. When the second frame body 3 opens and closes the first frame body 2, the second frame body 3 can be kept at an arbitrary opening and closing angle position by the opening and closing resistance.

(Effect of Example 1)

In Embodiment 1, the standing member rotation control means 35 turns the first assembly member 31 when the second frame 3 is superimposed on the closed position P0 of the first frame 2 to the open position P1, causing the standing The member 7 moves from the storage position Q0 to the action position Q1. Therefore, the supporting standing member 7 can be The mechanism that unfolds toward the rear of the second housing 3 is assembled in the hinge device 10. Outside the hinge device 10 connecting the first frame 2 and the second frame 3, there is no need to provide a mechanism that supports the standing member 7 and expands toward the rear of the second frame 3.

In Embodiment 1, the input member 18, the cam member 16, and the rotation transmission member 17 arranged around the hinge shaft 11 move the standing member 7 from the storage position Q0 to the action position Q1. Instead, it can move in the axial direction in a state where the rotation of the output member 19 is restricted, and is engaged with the input member 18 to transmit the rotation from the input member 18. The cam member 16, including the cam surfaces 16c and 16d, is in contact with the rotation transmission member 17 in a state where the rotation of the hinge shaft 11 and the movement in the axial direction are restricted, and the rotation transmission member 17 rotates with the rotation of the rotation transmission member 17 Move in the direction of the axis. The tendency member 21 makes the rotation transmission member 17 tend to the cam member 16 in the axial direction. Therefore, the mechanism that rotates the second assembly member 32 in conjunction with the rotation of the first assembly member 31 can be tightly housed around the hinge shaft.

In Embodiment 1, the hinge shaft 11 is assembled to the first frame body 2 and partially rotated. Therefore, a bearing that allows the hinge shaft 11 to freely rotate is not required. In addition, the first assembly member 31 is assembled to the second frame 3 rotatably around the hinge shaft 11, and the second assembly member 32 is assembled to the standing member 7 rotatably around the hinge shaft 11. Therefore, by using the hinge shaft 11 as the bearing member of the first assembly member 31 and the second assembly member 32, the arrangement of the dedicated bearing member can be omitted.

In the first embodiment, the standing member rotation control means 35 is to move the standing member 7 from the storage position Q0 to the predetermined action position Q1 between the rotation of the second frame 3 from the closed position P0 to the predetermined open position P1. , The rotation of the second assembly member 32 is controlled in response to the rotation of the first assembly member 31. Thereby, in conjunction with the rotation of the second frame 3 with respect to the first frame 2, the standing member 7 moves, and the first frame 2 and the second frame 3 are stably held. Therefore, by adopting a different structure from the past, the standing member 7 for stably maintaining the opening angle of the terminal device 1 on the mounting surface SM can respond to the opening operation of the second frame 3 to the first frame 2, The storage posture automatically moves into the action posture.

In the first embodiment, if the input member 18 is driven to rotate the rotation transmitting member 17 against the tendency member 21 to exceed the mountain top 16g, it is rotated by the tendency force of the tendency member 21 to be held at the valley bottoms 16e, 16f. Therefore, in conjunction with the rotation of the first assembly member 31, the second assembly member 32 can be rotated in the same direction as the first assembly member 31 with a larger rotation angle.

In Embodiment 1, the standing member rotation control means 35 is hinged to the first assembly member 31 When the rotation of the chain shaft 11 is less than 90 degrees, the second assembly member 32 rotates the hinge shaft 11 by 180 degrees or more. Thereby, even if the center of gravity of the second frame body 3 is located at the plane end of the first assembly member, the standing member 7 moves to the action position Q1, and the second frame body 3 can be held stably. In addition, even if the terminal device 1 is placed on an inclined surface lowered toward the rear, the second frame 3 can be held stably.

In Embodiment 1, the standing member rotation control means 35 is arranged around the hinge shaft 11. Therefore, the standing member rotation control means 35 is accommodated inside the hinge device 10 having an elongated appearance, and the hinge device can be miniaturized.

In the embodiment, the engaged portion 17m of the rotation transmission member 17 is formed to protrude in the axial direction so as to be engaged with the input member 18 that rotates. The pair of engaging portions 18c and 18d of the input member 18 can be engaged with the end surfaces of the engaged portion 17m in the rotational direction, respectively, and are arranged at opposite intervals with a width wider than the engaged portion 17m to rotate Hold the engaged portion 17m in the direction. Therefore, when the second frame 3 is rotated from the closed position (0 degrees) to the open position (85 degrees), the second frame 3 is rotated from the open position (85 degrees) to the closed position (0 degrees) At this time, the engaging portions 18c and 18d respectively function. Thereby, the gap between the engaging portions 18c and 18d and the engaged portion 17m can be secured, and the timing for moving the standing member 7 from the storage position Q0 to the action position Q1 can be arbitrarily set.

In Embodiment 1, the facing angle of the rotating direction of the engaging portions 18c and 18d is the angle of the rotating direction of the engaged portion 17m, plus the angle from the top of the mountain 16g to the bottom 16f. Therefore, the second assembly member 32 can be kept below the action position Q1, and the tilt state of the second frame 3 can be adjusted arbitrarily within a predetermined range.

In Embodiment 1, during the rotation of the first assembly member 31 from the closed position P0 by approximately 90 degrees, the second assembly member 32 rotates by approximately 180 degrees. After that, during the rotation of the first assembly member 31 from about 90 degrees to about 130 degrees, the rotation is not transmitted to the second assembly member 32. Therefore, in the range of the predetermined opening position P1 (85 degrees to 135 degrees), even if the second frame 3 rotates, the standing member 7 is stably maintained at the action position Q1.

In the first embodiment, inclined surfaces 17j and 18j are provided on the opposing surfaces of the engaging portions 18c and 18d of the engaged portion 17m. The inclined surfaces 17j and 18j are accompanied by the movement of the rotation transmission member 17 in the axial direction guided by the cam surface 16c, so that the rotation amount of the rotation transmission member 17 is greater than the rotation amount of the input member 18. Thereby, it can be linked with the rotation of the first assembly member 31, so that the second assembly member 32 faces the first assembly The member 31 rotates in the same direction and at a larger rotation angle. The rotation of the first assembly member 31 that is less than 90 degrees can be used to extract the rotation of the second assembly member 32 that is more than 180 degrees.

In the first embodiment, the inclined surfaces 17j and 18j are provided such that the rotation transmission member 17 starts to engage with the rotation transmission member 17 from the position where the valley bottoms 16e and 16f are disengaged. Therefore, the initial moment when the standing member 7 moves toward the storage position Q0 is reduced, and the operability when the standing member 7 is deployed can be improved.

In Embodiment 1, the hinge shaft 11 has an assembly portion 11a for the first frame 2 at one end in the axial direction. The first assembly member 31 is arranged between the second assembly member 32 and the assembly portion 11a in the axial direction. Therefore, in Embodiment 1, the pair of hinge devices 10 arrange the second assembly members at both ends in the axial direction. Therefore, the standing member 7 with a wide grounding range can move symmetrically and stably between the storage position Q0 and the action position Q1.

(Other embodiments)

It can also be used for various machines or containers in which an arbitrarily selected first frame body and second frame body are connected by a hinge device 10 in an openable and closable manner.

The timing of the start/end of movement of the standing member 7 accompanying the opening and closing operation of the second frame 3 is not limited to those of the embodiment.

In Embodiment 1, the opening angle of the second frame 3 to the closing position P0 of the first frame 2 is set to 0 degrees, and the opening angle of the opening position P1 is set to 85 degrees to 135 degrees, but the second frame 3 The opening angles of the closed position P0 and the open position P1 of the first frame 2 can also be set to a range other than the fixed angle. Furthermore, in Embodiment 1, the opening angle of the standing member 7 to the storage position Q0 of the first frame 2 is set to 0 degrees, and the opening angle of the action position Q1 is set to 180 degrees, but the standing member 7 The opening angle of the storage position Q0 and the action position Q1 of the first frame 2 can also be set to a range other than it or a fixed angle.

In Embodiment 1, the hinge shaft 10 is arranged between the assembly portion 11a of the hinge shaft 11 and the second assembly member 32 in the axial direction, and the assembly portion 11a of the hinge shaft 11 is disposed in the axial direction Inside. However, the arrangement of the assembly portion 11a of the hinge shaft 11 and the second assembly member 32 and the first assembly member 31 in the axial direction, the arrangement order of the inner and outer sides of the axial direction of the arrangement order, may also be a combination other than this.

In the first embodiment, the hinge device 10 is arranged symmetrically to the left and right of the terminal device 1, but the number of the hinge device 10 may be one or more than three. When a pair of hinge devices are provided, it is not necessary for both to be the hinge devices 10. One of them may be replaced with one without the discharge member 20 or the friction torque generating member 14.
