The first hinge pin 16, the second hinge pin 18, the third hinge pin 40, and the fourth hinge pin 42 are fixed to the first base plate 9, the second base plate 10, the first mounting member 17, and the second mounting member 41, respectively. The first link arm 19, the second link arm 20, the third link arm 43, and the fourth link arm 44 are respectively connected to the first hinge pin 16, the second hinge pin 18, the third hinge pin 40, and the fourth hinge pin 42. Rotation is not constrained. Further, the first link disk 31 and the second link disk 49 are rotatable about the first mounting shaft 29 and the second mounting shaft 47, and the first link bases 34, 34 and the second link bases 52, 52 are The rotation of the first and second hinge pins 16 and 18 and the third and fourth hinge pins 40 and 42 is restricted.

  Therefore, during the lift-down operation of the second housing 3, the first link arm 19, the second link arm 20, the third link arm 43, and the fourth link arm 44 support the second hinge pin 18 and the fourth hinge pin 42. The first hinge pin 16 and the third hinge pin 40 are rotated together with the second hinge pin as the first link arm 19, the second link arm 20, the third link arm 43 and the fourth link arm 44 rotate. 18 and the fourth hinge pin 42 are pivoted. And the 1st stopper arm accompanying the rotation operation | movement of the 1st link arm 19 and the 2nd link arm 20, the 3rd link arm 43, and the 4th link arm 44 accompanying the lift-down operation | movement of the 2nd housing | casing 3 The movements of the first and third link arms 19 and 51 are fixed to the first and third link arms 19 and 43 by the rotation of the first and third link arms 19 and 43, respectively. The link bases 34 and 34 and the second link bases 52 and 52 rotate in opposite directions, respectively, and by this rotation operation, the first stopper arm 33 and the second stopper arm 51 are pushed and the first and first stopper arms 51 are pushed. As the two-link discs 31 and 49 rotate, the other first stopper arm 33 and second stopper arm 51 also oscillate and operate with respect to each other. It is linked.

  Here, the movements of the first stopper arms 33 and 33 and the second stopper arms 51 and 51 of the first link mechanism 15 and the second link mechanism 45 are set in reverse but operate in the same direction. You may comprise so that it may do.

  During the lift-down operation of the second casing 3, the second casing 3 does not rotate with the first hinge pin 16 and the third hinge pin 40 as fulcrums. The first stopper arms 33 and 33 and the second stopper This is because the rotation operation is restricted by the link operation of the arms 51 and 51.

  If the second link mechanism 45 of the second hinge means 7 on the right side is omitted, the link operation is performed without any trouble by the operation of only the first link mechanism 15 of the first hinge means 6 on the left side.

  Next, the operational effects of the switchgear according to the present invention and a small electronic device using the switchgear will be described.

  First, as shown in FIG. 1, in the closed state in which the second housing 3 is closed with respect to the first housing 2, the first hinge means 6 and the first hinge of the second hinge means 7. The side portions of the case 6a and the second hinge case 7a abut against the front end portions 2c and 2c of the housing recesses 2b and 2b provided in the first housing 2, and in this state, the elastic means 12 and 12 of the slide mechanism 5 are provided. Pushes the second housing 3 in the closing direction via the slide base member 8, so that the second housing 3 is locked in the closed state.

  Further, in this closed state, even if it is attempted to open the second casing 3 in the vertical direction with respect to the first casing 2, as shown in FIG. The first hinge case 6a of the second hinge means 7 and the stopper portions 6d, 7d of the second hinge case 7a hit the ceiling portions 3d, 3d of the hinge case receiving grooves 3b, 3b; Because of the rotation inhibiting function of the second link mechanism 45 with respect to the second casing 3, the second casing 3 cannot be opened in the vertical direction.

  In using the pocket computer 1, when the second housing 3 is pushed backward to expose the upper surface of the first housing 2, the slide plate 11 of the slide mechanism 5 moves against the slide base member 8. The first housing 3 is opened by sliding against the elastic force of the elastic means 12, 12. When the intermediate open position is exceeded, the second casing 3 is opened by the elastic force when the compressed elastic means 12, 12 is extended. It is pushed in the direction and is automatically opened with respect to the first housing 2.

  Even if an attempt is made to open the second casing 3 in the vertical direction with respect to the first casing 2 in the middle of the opening / closing operation, the second casing 3 with respect to the first link mechanism 15 and the second link mechanism 45 has The rotation preventing function and the stopper portions 6d and 7d of the first hinge case 6a and the second hinge case 7a cannot be opened due to contact with the ceiling portions 3d and 3d of the hinge case receiving grooves 3b and 3b.

  As shown in FIGS. 2 and 5B, when the slide opening operation of the second housing 3 with respect to the first housing 2 by the slide mechanism 5 is completed, the first hinge means 6 and the second hinge The first hinge case 6a and the second hinge case 7a of the means 7 are located at the positions of the recesses 3c and 3c of the hinge case receiving grooves 3b and 3b, but the second case 3 is used as the first case 2. The first hinge means 6 and the second hinge means 7 are provided with the first link mechanism 15 and the second link mechanism 45, so that the second casing 3 is the first one. Since it does not operate so as to open up and down with respect to one casing 2, it cannot be opened up and down.

  When the second casing 3 is lifted down with respect to the first casing 2, as shown in FIGS. 3 and 5C, the second casing 3 is further pushed backward. The stopper portions 6d and 7d of the first hinge case 6a and the second hinge case 7a of the first hinge means 6 and the second hinge means 7 are located in the recesses 3c and 3c of the hinge case receiving grooves 3b and 3b. Thus, the first hinge case 6a and the second hinge case 7a rotate around the second hinge pin 18 and the fourth hinge pin 42 as a fulcrum, and the second casing 3 further moves in the horizontal state rearward. However, as shown in FIG. 5 (c), the upper front end portions of the first hinge case 6a and the second hinge case 7a hit the corner portions 3f and 3f of the recesses 3c and 3c. Stop at. By pushing the second housing 3 from the upper surface at this stop position, as shown in FIGS. 3, 4 and 5, the second housing 3 is the first housing. The first housing 2 is lifted down while being kept in a parallel state with respect to the other housing 2 and is juxtaposed on a desk, for example.

  During the lift-down operation, the cam recesses 24b, 24b, 24b, 24b of the first cam members 24, 24 of the rotation control means 14 provided in the first hinge means 6 on the left side of the second housing 3 and the second cams. The lift-down operation of the second housing 3 is controlled by the cam projections 25a, 25a, 25a, and 25a of the members 25 and 25, and does not naturally fall by its own weight. It is also possible to stop the click at the position at the start of the lift-down operation and the position at the end of the lift-down operation.

  During the lift-down operation, the first link mechanism 15 and the second link mechanism 45 operate, and the second casing 3 is lifted down and grounded while maintaining a horizontal and parallel state with respect to the first casing 2. However, it can be flush with the first housing 2.

  That is, the second housing 3 is moved toward the lift-down operation from the end state of the sliding mechanism 5 toward the opening direction of the second housing 3 with respect to the first housing 2. As shown in FIG. 5B, the first hinge case 6a and the second hinge case 7a are in the recesses 3c and 3c so that the lift-down operation is possible. It becomes. Then, the first stopper arms 33 and 33 and the second stopper arms 51 and 51 move in the opposite directions, respectively, while the first link arm 19 and the second link arm 20, the third link arm 43 and the fourth link arm 44 are moved. The rotation operation with the second hinge pin 18 and the fourth hinge pin 42 as a fulcrum is allowed, and the second housing 3 is lifted down while maintaining the horizontal state. This lift-down operation is performed when the second housing 3 is in a grounded state, and as shown in FIGS. 17 and 18D, the tip of the second housing 3 is moved to the first housing 2. Finish by hitting the rear edge of the.

  When returning the second casing 3 that has been lifted down, when the second casing 3 is lifted, the first link mechanism 15 and the second link mechanism 45 operate, and the second casing 3 By performing the lift-up operation opposite to that described above, the state before the lift-down operation is restored, and the rotation operations of the first link arm 19, the second link arm 20, the third link arm 43, and the fourth link arm 44 are performed. finish.

  Next, by pulling the second housing 3 forward, the second housing 3 is slid by the slide mechanism 5 and returned to the original position. When the second casing 3 slides back to the original position, the elastic means 12 and 12 are once compressed and expanded, so that the second casing 3 is moved by the biasing force to the first casing 3. The body 2 is automatically closed from the middle of the sliding operation, and the first hinge case 6a and the second hinge case 7a are brought into contact with the front end portions 2c and 2c of the housing recesses 2b and 2b, thereby completing the operation. A stable state will be maintained.

  In addition, although the 1st attachment member 17 and the 2nd attachment member 41 are attaching each side plate 17a and 41a downward, these can be attached arbitrarily upwards. Further, when the second casing 3 is lifted down with respect to the first casing 2 and juxtaposed with the first casing 2, the second casing 3 becomes the first casing 2. In addition, although what is grounded is shown, it is also arbitrary that the gap is formed on the lower surface of the second casing 3. Furthermore, it is desirable that when the second housing 3 is lifted down, the upper surface of the first housing 2 and the upper surface of the second housing 3 are flush with each other, but this is not the only case. Not.

  Further, the E-rings 53 and 53 of the second hinge means 7 may be omitted when the edge of the third link arm 43 is fitted to the inner peripheral groove 7e of the second hinge case 7a. The first cam members 24, 24 and the second cam members 25, 25 of the rotation control means 14 can also be simply friction washers.

  Since the present invention is configured as described above, the second casing can be opened and closed by sliding it horizontally with respect to the first casing, and after the opening operation is completed, the second casing is moved to the first casing. Since it can be lifted down and juxtaposed while maintaining a horizontal state with respect to the housing, it is suitable as an opening / closing device for small electronic devices such as pocket computers, PDAs, electronic dictionaries, and mobile phones for performing new operations. It can be used, and a device that performs a new operation as a small electronic device can be provided.
