  Next, the operation of the opening / closing device 1 described above will be described.

  First, as shown in FIGS. 1 and 7, when the second casing 4 is closed with respect to the first casing 3 and is in a closed state, and completely overlaps with each other, the swivel member 10 is The shaft portion 9a of the attached rotating shaft 9 is engaged with a stopper recess 6b provided in the guide hole 6a of the base member 6, and the rotating shaft 9, the small-diameter disk 8, the central axes of the rotating disk 7, and the rotating disk. As shown in FIG. 30, the central axis of the guide slot 7b provided in 7 is on a straight line. Further, since the shaft portion 9a of the rotary shaft 9 falls into the stopper recess 6b by the click stopping means 12, and this state is maintained by the elasticity of the elastic means 13, the second casing 4 is fixed to the first casing 3. As long as no force is applied in either the left or right rotational direction, the closed state is stably maintained. In particular, as shown in FIG. 7, the fixed locking members 14 and 14 at both ends of the turning member 10 are in a state in which the locking portions 14a and 14a face downward. Further, as shown in FIG. 7, the movable locking members 22, 22 are both turned and biased by the respective sub-elastic means 23, and the locking pins 20 of the arc-shaped guide holes 11 of the cover plate 16. It exists in the start end part 11a, and it exists in the position which exhibits reverse C shape in both. Further, as shown in FIG. 7 (b), the guide protrusions 6j and 6k are sandwiched between the deformation mounting pin portion 14c and the engagement pin portion 14b of each fixed locking member 14, whereby the turning member 10 The posture is stabilized.

  From the closed state of FIG. 7, when the second casing 4 is pushed, for example, in the horizontal direction in the clockwise direction with respect to the first casing 3, the second casing 4 is connected to the right joint recess 6g. Rotating in the clockwise direction in the horizontal direction with the rotating shaft 9 as a fulcrum, with the deformation mounting pin portion 14c of the fixed locking member 14 falling into the fulcrum as the fulcrum, FIG. As shown, the small-diameter disk 8 is eccentrically rotated clockwise with the rotating shaft 9 as a fulcrum, and at the same time, the rotating disk 7 is urged to rotate counterclockwise due to the eccentric rotation of the small-diameter disk 8. Does not rotate at a fixed position, but rotates and draws an asteroid curve as shown in FIG. Then, as shown in FIG. 8, the elastic means 13 is in the most bent state at a rotation angle of 45 degrees in the clockwise direction with respect to the first casing 3 of the second casing 4, and the swiveling members 10 are both It is in a position turned 45 degrees. And the thing located in the left side of the fixed locking member 14 has removed the guide convex part 6k, but the thing located in the right side has the engaging pin part 14b inserted in the joining recessed part 6g of the base member 6. Yes. At this time, the one located on the right side of the fixed locking member 14 has the deformation mounting pin portion 14c and the engagement pin portion 14b holding the guide protrusion 6j. The deformation mounting pin portion 14c and the engaging pin portion 14b are protruded from the guide protrusion 6k.

  Next, from the state shown in FIG. 8, as shown in FIG. 9, the second casing 4 is further rotated clockwise with respect to the first casing 3 and rotated 90 degrees from the closed state. In this state, as the rotating shaft 9 rotates, the small-diameter disk 8 further eccentrically rotates clockwise with the rotating shaft 9 as a fulcrum, and the rotating disk 7 rotates counterclockwise due to the eccentric rotation of the small-diameter disk 8. Therefore, the rotation of the rotary shaft 9 is not a fixed position rotation, but rotates and moves while drawing an asteroid curve as shown in FIG. Then, the elastic means 13 extends from the most bent state of FIG. 8 at a clockwise rotation angle of 90 degrees with respect to the first casing 3 of the second casing 4, so that the second casing 4 is The shaft portion 9a of the rotary shaft 9 constituting the click stopping means 12 that automatically rotates clockwise with respect to the first housing 3 and is attached to the turning member 10 at a rotation angle of 90 degrees is the base member 6. It falls into the second stopper recess 6c, and this state is maintained by the elastic means 13, and since the rotation angle of 90 degrees is stably maintained, the second casing 4 is rotated at the rotation angle of 90 degrees. Can be used to operate the operation unit 3a (shown in FIG. 2) of the first housing 3. At the end of the rotation, the deformation mounting pin portions 14c and 14c and the engagement pin portions 14b and 14b of the fixed locking members 14 and 14 sandwich the guide protrusions 6j and 6n.

  Next, from the state shown in FIG. 9, as shown in FIG. 10, the second housing 4 is further rotated clockwise by 45 degrees with respect to the first housing 3, and the state shown in FIG. 7 in the state where the swiveling member 10 is rotated by 135 degrees from the state shown in FIG. 7, the deformation mounting pin portion 14 c and the engaging pin portion 14 b of the right fixed locking member 14 in the state of FIG. Since the left fixed locking member 14 in FIG. 6 falls into the joint recess 6h and pivots about the deformable mounting pin portion 14c, the guide protrusion 6j is escaped.

  Next, as shown in FIG. 11, the second housing 4 is further rotated clockwise by 45 degrees from the state shown in FIG. When the rotary shaft 9 is rotated 180 degrees from the closed state, the small-diameter disk 8 is eccentrically rotated clockwise with the rotary shaft 9 as a fulcrum, and the rotary disk 7 is rotated by the eccentric rotation of the small-diameter disk 8. Since the rotation is performed in the counterclockwise direction, the rotation of the rotation shaft 9 is not a fixed position rotation, but is rotated while drawing an asteroid curve as shown in FIG. Then, the elastic means 13 extends from the most bent state of FIG. 10 at a clockwise rotation angle of 180 degrees with respect to the first casing 3 of the second casing 4, so that the second casing 4 is The shaft portion 9a of the rotating shaft 9 attached to the turning member 10 is engaged with the stopper recess 6d of the base member 6 at a rotation angle of 180 degrees. Since the rotation angle of 180 degrees is stably maintained, the second casing 4 is used in a vertically long position at the rotation angle of 180 degrees, and the operation unit 3a (shown in FIG. 2) of the first casing 3 is used. The operation can be performed. At the time of this rotation, the fixed locking member 14 located on the left side of the turning member 10 shown in FIG. 7 engages with the locking pin 20 of the movable locking member 22 on the right side in the drawing at its locking portion 14a. The fixed locking member 14 located on the right side in the state of FIG. 7 has its locking portion 14 a with the locking pin 20 of the movable locking member 22 resisting the elasticity of the sub elastic means 23, and the terminal portion of the arcuate guide hole 11. The movable locking member 22 pushed by the fixed locking member 14 by retracting the movable locking member 22 by pushing it counterclockwise on the 11b side hits the base member 6. Therefore, clockwise rotation of 180 degrees or more with respect to the first casing 3 of the second casing 4 is prevented. FIG. 21 shows an enlarged view of this state.

  Next, the case of the counterclockwise rotation operation when performing the opening / closing operation of the second casing 4 on the first casing 3 will be described.

  First, when the second casing 4 is pushed in the counterclockwise direction in the horizontal direction with respect to the first casing 3 from the closed state of FIG. While the rotating shaft 9 is also used as a fulcrum while rotating with the deformation mounting pin portion 14c of the fixed locking member 14 falling to 6f as a fulcrum, the rotation shaft 9 rotates as the rotation shaft 9 rotates. As shown in FIG. 12, the small-diameter disk 8 rotates eccentrically in the counterclockwise direction with the rotating shaft 9 as a fulcrum, and at the same time, the rotating disk 7 urges the clockwise rotation by the eccentric rotation of the small-diameter disk 8, This rotation is not a fixed position rotation, but rotates and moves while drawing an asteroid curve as shown in FIG. Then, as shown in FIG. 13, the elastic means 13 is in the most bent state at a rotation angle of 45 degrees counterclockwise with respect to the first housing 3 of the second housing 4, and the turning member 10. Are both turned 45 degrees. And what is located on the right side of the fixed locking member 14 has removed the joint recess 6g, but what is located on the left side remains in a state where its engaging pin portion 14b is fitted into the joint recess 6f of the base member 6. It is. At this time, the one located on the left side of the fixed locking member 14 has the deformation mounting pin portion 14c and the engaging pin portion 14b sandwiching the guide ridge portion 6k, while the one on the right side is The deformation mounting pin portion 14c and the engaging pin portion 14b are protruded from the guide protrusion 6j.

  Next, from the state shown in FIG. 12, as shown in FIG. 13, the second casing 4 is further rotated clockwise by 45 degrees with respect to the first casing 3 to 90 degrees from the closed state. In the rotated state, as the rotating shaft 9 rotates, the small-diameter disk 8 further rotates eccentrically counterclockwise with the rotating shaft 9 as a fulcrum, and the rotating disk 7 rotates clockwise due to the eccentric rotation of the small-diameter disk 8. Therefore, the rotation of the rotary shaft 9 is not a fixed position rotation but a left rotation movement while drawing an asteroid curve as shown in FIG. Then, the elastic means 13 extends from the most bent state of FIG. 12 at a counterclockwise rotation angle of 90 degrees with respect to the first casing 3 of the second casing 4. Is automatically rotated counterclockwise with respect to the first casing 3, and the shaft portion 9a of the rotary shaft 9 constituting the click stopping means 12 attached to the turning member 10 is rotated at a rotation angle of 90 degrees as a base member. 6, the state is maintained by the elastic means 13, and the rotation angle of 90 degrees is stably maintained, so that the second casing 4 is rotated at the rotation angle of 90 degrees. Can be used to operate the operation unit 3a (shown in FIG. 2) of the first housing 3. At the time of this rotation, the fixed locking member 14 pivots on the left deformation mounting pin portion 14c in the state of FIG. 7 and is located on the right side of the fixed locking member 14 as shown in FIG. The deformation mounting pin portion 14c and the engaging pin portion 14b sandwich the guide protrusion 6m.

  Next, from the state shown in FIG. 13, as shown in FIG. 14, the second housing 4 is further rotated 45 degrees counterclockwise with respect to the first housing 3, and the FIG. In the state rotated 135 degrees from the state, the deformation mounting pin portion 14c and the engaging pin portion 14b of the left locking member 14 in the state of FIG. 7 of the turning member 10 are fixed to the right side of the turning member 10. Since the deformation mounting pin portion 14c of the locking member 14 falls into the joint recess 6i and pivots about the deformation mounting pin portion 14c, the deformation mounting pin portion 14c of the left fixed locking member 14 and the engagement pin The part 14b has escaped the guide protrusion 6k.

  Next, from the state shown in FIG. 14, as shown in FIG. 15, the second housing 4 is further rotated 45 degrees counterclockwise with respect to the first housing 3. When the rotary shaft 9 is rotated 180 degrees from the closed state, the small-diameter disk 8 rotates eccentrically counterclockwise with the rotary shaft 9 as a fulcrum, and the rotary disk 7 is rotated by the eccentric rotation of the small-diameter disk 8. Since the rotation is performed in the clockwise direction, the rotation of the rotation shaft 9 is not a fixed position rotation, but is rotated while drawing an asteroid curve as shown in FIG. Then, the elastic means 13 expands from the most bent state of FIG. 14 at a counterclockwise rotation angle of 180 degrees with respect to the first casing 3 of the second casing 4. Automatically rotates counterclockwise with respect to the first housing 3, and the shaft portion 9 a of the rotation shaft 9 of the click stopping means 12 attached to the turning member 10 is rotated by 180 ° with respect to the base member 6. Since the rotation angle of 180 degrees is stably maintained by engaging with the stopper recess 6d, the operation portion 3a of the first case 3 is used with the second case 4 being vertically long at the rotation angle of 180 degrees. (Displayed in FIG. 2) can be performed. At the time of this rotation, the fixed locking member 14 located on the right side of the turning member 10 in the state shown in FIG. 7 is connected to the locking pin 20 of the movable locking member 22 located on the left side in the drawing by the locking portion 14a. The locking pin 20 of the right movable locking member 22 is made elastic by the sub-elastic means 23 by the locking portion 14a of the fixed locking member 14 that is engaged and located on the left side of the swiveling member 10 shown in FIG. The movable locking member 22 is retracted by pushing it clockwise. Therefore, the counterclockwise rotation of 180 degrees or more with respect to the first casing 3 of the second casing 4 is prevented. FIG. 22 shows an enlarged view of this state.

  As described above, when the second casing 4 rotates clockwise or counterclockwise with respect to the first casing 3, the rotating shaft 9 and the rotating disc 7 rotate 90 degrees and 180 degrees, but the small diameter disk Since the mounting position is determined so that 8 rotates 360 degrees each time, the rotation locus of the rotating shaft 9 draws an asteroid curve as shown in FIG.

  The movement of the small-diameter disk 8 during the rotation operation of the second casing 4 with respect to the first casing 3 as described above is as shown in FIGS. 16 to 20 and FIG. The disk 8 moves while rotating in the elliptical recess 7a provided in the rotating disk 7 together with the rotating shaft 9 moving in the guide long hole 7b during the rotating operation of the second casing 4 with respect to the first casing 3. . In the present invention, this operation causes the rotating shaft 9 to perform an asteroid operation.

  Further, when the second casing 4 is opened and closed in the counterclockwise direction with respect to the first casing 3, the flange portion 9b at the lower end portion of the rotary shaft 9 has a cover plate as shown in FIGS. The asteroid operation is performed along the 16 cutout portions 16b, and the engagement recesses 16c to 16f provided in the cutout portion 16b are sequentially fitted at rotation angles of 0 degrees, 90 degrees, and 180 degrees. Although the drawing is omitted for the clockwise rotation of the second housing 4 with respect to the first housing 3, the flange portion 9 b at the lower end portion of the rotating shaft 9 is cut out from the cutout portion 16 b of the cover plate 16. Asteroid operation is performed along with the rotation, and at the rotation angles of 0 degrees, 90 degrees, and 180 degrees, when rotating in the clockwise direction, the engagement recesses 16c, 16f, and 16e provided in the cutout portion 16b are sequentially inserted and counterclockwise. During the rotation, the engagement recesses 16c, 16d, and 16e are sequentially inserted.

  The slide preventing means 61 for preventing the base member 6 and thus the second housing 4 from sliding in the linear direction with respect to the first housing 3 includes stopper recesses 6b, 6c, 6d of the guide hole 6a of the base member 6. Inclined portions 61a, 61b, 61c, 61d, 61e, 61f, 61g, 61h provided from 6e to the joint recesses 6f, 6g, 6h, 6i, and deformation mounting pin portions 14c, 14c of the fixing locking members 14, 14 In particular, as shown in FIGS. 1 to 4 and FIGS. 7, 9, 11, 13, and 15, the first housing 3 and the second housing 4 are closed. When the user rotates the second casing 4 with respect to the first casing 3 in the clockwise direction and counterclockwise 90 degrees from the closed state and the closed state, the original operation method of the switchgear according to the present invention Try to slide back and forth or left and right In this case, as shown in FIGS. 23A to 23C, the deformation mounting pin portions 14 c and 14 c of the fixed locking members 14 and 14 are connected to the first housing 3 of the second housing 4. Is engaged with the inclined portions 61a to 61h of the guide hole 6a of the base member 6 to prevent the second casing 4 from sliding. That is, as shown in FIGS. 1 and 7, in the closed state in which the second housing 4 is closed with respect to the first housing 3, the second housing 4 is replaced with the first housing 3. On the other hand, when trying to slide in the front-rear direction, even if the second housing 4 slides slightly forward with respect to the first housing 3, as indicated by an imaginary line in FIG. The deformation mounting pin portions 14c and 14c of the turning member 10 are brought into contact with and engaged with the inclined portions 61a and 61d, and further sliding operation of the second housing 4 with respect to the first housing 3 is prevented.

  Next, in a state where the second casing 4 is rotated 90 degrees clockwise with respect to the first casing 3 as shown in FIGS. When the left side of the casing 3 is slid to the left, as shown by an imaginary line in FIG. When 14c and 14c contact and engage with the inclined portions 61c and 61f, further sliding operation in the left direction is prevented.

  Next, as shown in FIGS. 3 and 13, in a state where the second housing 4 is rotated 90 degrees counterclockwise with respect to the first housing 3, the second housing 4 is moved. Even if it is intended to slide to the right with respect to the first housing 3, it slightly slides to the right as indicated by the imaginary line in FIG. Since the portions 14c and 14c are in contact with and engaged with the inclined portions 61b and 61g, further sliding operation in the right direction is prevented.

  When the second casing 4 is rotated 180 degrees by rotating in the clockwise direction or the counterclockwise direction with respect to the first casing 3, as shown in FIGS. 11 and 15, Since one of the left and right deformation mounting pin portions 14c and 14c of the turning member 10 is locked by one of the movable locking members 22 and 22 depending on the rotation direction, the second casing 4 is moved by this engagement. Even if the first casing 3 is slid forward and closed, the second casing 4 does not slide with respect to the first casing 3.

  At the end of the 0 °, 90 °, and 180 ° rotation operations of the second housing 4 with respect to the first housing 3, the deformation mounting pin portions 14c and 14c fall into the respective joint recesses 6f, 6g, 6h, and 6i. Therefore, in the case of (a) in FIG. 23, the slide operation is not performed in the forward direction, in the case of (b) in the right direction, and in the case of (c), the slide operation is not performed in the left direction.

  Next, as shown in FIG. 24, the rotation fulcrum adjusting means 62 when the second casing 4 rotates with respect to the first casing 3 is engaged with the fixed locking members 14 and 14. It comprises pin portions 14b, 14b and thin guide portions 62a, 62b, 62c, 62d provided at the corners of the guide protrusions 6j, 6k, 6m, 6n of the base member 6. That is, as shown in FIGS. 1 to 4 and FIGS. 7, 9, 11, 13, and 15, the second casing 4 is 0 degrees, 90 degrees, and 180 degrees with respect to the first casing 3. As described above, when the deformation attachment pin portions 14c and 14c are to be slid in the direction of engagement with the inclined portions 61a to 61h as described above, the deformation attachment pin portions 14c and 14c are finished. Until it comes into contact with the inclined portions 61a to 61h. In this slid state, the second housing 4 is rotated with respect to the first housing 3 as shown in FIGS. 1 to 3 and FIGS. 7, 9, 11, 13, and 15. In such a case, since the deformation mounting pin portions 14c and 14c serving as the pivots are not in the respective joint recesses 6f, 6g, 6h, and 6i, there is a risk that a smooth asteroid operation cannot be performed. There is. In this case, the rotation fulcrum adjusting means 62 functions.

  In this case, when the second casing 4 is rotated clockwise with respect to the first casing 3, one of the engaging pin portions 14b accompanying the rotation operation is particularly shown in FIG. As shown in the figure, it is guided by the thin guide portion 62b and moves downward as indicated by an imaginary line in the figure, so that the deformable mounting pin portion 14c serving as a fulcrum is dropped into the joint recess 6g. It adjusts so that steroid movement can be performed. FIG. 24 shows the second casing 4 with respect to the first casing 3, particularly when the second casing 4 is slid backward from the closed state with respect to the first casing 3. As shown in FIG. 8, the clockwise rotation is illustrated, but one of the deformation mounting pin portions 14c and 14c is joined even when rotated 90 degrees in any other left and right directions. Since the second casing 4 is rotated with respect to the first casing 3 without being in the recesses 6g, 6f, and 6i, the rotation fulcrum is adjusted in the same manner. Description is omitted.

  Since the present invention is configured as described above, the second housing is placed on either the left or right side of the first housing from the state in which the second housing is almost completely overlapped with the first housing. And 90 degrees and 180 degrees in the horizontal direction, the second casing can be used horizontally and vertically with respect to the first casing, and the upper surface of the first casing Since the operation part can be exposed operably, it is easy for both right-handed and left-handed persons to open and close, so that the top surface is the same as the first case provided with an operation part such as a keyboard on the top surface. It can be suitably used as an opening / closing device for a portable device such as a mobile phone, an electronic dictionary, a pocket computer, a PDA, etc., and a portable device using this opening / closing device.
