  The rail member 9 is a substantially rectangular sheet metal fixed to the lower surface of the second housing 2, and rails 91 are formed along the left and right sides thereof. The pair of left and right rails 91 is U-shaped in cross section, and the open sides thereof are opposed to each other, and a sliding member 92 made of POM (polyacetal) is fitted inside the rail 91. The sliding direction guide portion 51 and the rotational direction guide portion 52 of the support member 5 and the sliding direction guide portion 61 and the rotational direction guide 62 of the movable member 6 can be engaged with the sliding groove of the sliding member 92, respectively. It has become.

  The other end of the torsion spring 7 is connected by a fixture 72 slightly below the left side of the rail member 9 in the drawing. A wiring through hole 96 is formed in the middle portion of the rail member 9 on the right side of the fixed portion 72 in the figure.

  FIG. 4 shows the rail member 9 as viewed from the opposite side. As shown in the figure, a protruding portion 93 that is parallel to the vicinity of one rail 91 is formed on one end portion side of the rail member 9. In the slide closed state, the protruding portion 93 abuts on the fixing member 53 for assembling the movable member 6 to the support member 5 from the side to restrict the rotation of the rail member 9.

Next, FIG. 5 shows the operation of the slide rotation hinge as viewed from the front.
First, in the slide closed state, as shown in FIG. 5A, the rail member 9 fixed to the lower surface of the second housing 2 is such that the upper end in the figure of the pair of left and right rails 91 is the first housing. 1 is engaged with the sliding direction guide portion 51 by a linear portion along the left side portion of the support member 5 fixed to the upper surface of the support member 5 and along the right side portion of the movable member 6 assembled on the support member 5. It is engaged with the slide direction guide portion 61 by the straight portion.

  In the slide closed state described above, the slide direction guide portion 51 of the support member 5 fixed to the first casing 1 is engaged with the rail 91 on the left side of the rail member 9 fixed to the second casing 2. In addition, the protruding portion 93 that is parallel to the vicinity of one rail 91 on one end portion side of the rail member 9 abuts on the fixing member 53 that attaches the movable member 6 to the support member 5 from the side, so that the rail member 9, that is, the second casing 2 cannot rotate. Therefore, the fixture 53 and the protruding portion 93 function as a rotation restricting portion.

  Further, at this time, the torsion spring 7 generates an elastic force so as to press the rail member 9 downward through the fixture 72 as shown by an arrow. Therefore, the slide closed state is maintained.

  In the middle of the sliding operation in which the first housing 1 and the second housing 2 are relatively slid, before the protruding portion 93 of the rail member 9 comes out of the fixture 53, FIGS. As shown in FIG. 6, the fixing member 72 for assembling the torsion spring 7 to the rail member 9 hits the inner wall of the sliding direction guide portion 51 of the support member 5, so that the second casing 2 cannot continue to rotate. Therefore, the inner wall of the sliding direction guide portion 51 and the fixture 72 function as a rotation restricting portion.

  Further, during the sliding, the fixing tool 72 for assembling the torsion spring 7 to the rail member 9 is also slid, so that the direction of the elastic force of the torsion spring 7 changes as shown by the arrow in FIG. If the slide amount is exceeded, the slide opening assist force is obtained.

  Further, in the slide open state, as shown in FIG. 5C, the lower end side of the rail 91 of the rail member 9 is engaged with the sliding direction guide portions 51 and 61 of the support member 5 and the movable member 6 to slide completely. Reached the position.

  At this time, since there is no contact for suppressing the rotation operation, the rail member 9 can rotate around the shaft portion of the fixture 72 to which the torsion spring 7 is assembled. That is, the fixing tool 72 is surrounded on the left side and the upper side in the figure by the sliding direction guide part 51 and the rotation direction guide part 52 of the support member 5, and is surrounded on the right side in the figure by the stopper 8, so You can only rotate on the spot. Accordingly, the slide direction guide portion 51, the rotation direction guide portion 52, the fixture 72, and the stopper 8 function as a rotation permission portion.

Next, FIG. 6 shows the rotation operation.
FIG. 6A shows the middle of rotation from the slide open state of FIG. 5C. When the second casing 2 is rotated with respect to the first casing 1, the torsion spring 7 is fixed. The rail member 9 rotates around the tool 72.

  At this time, the rail 91 on the left side in the figure engages with the curved part of the rotational direction guide part 52 of the support member 5, and the rail 91 on the right side in the figure engages with the curved part of the rotational direction guide part 62 of the movable member 6, At the same time, the movable member 6 is pushed by the rail 91 on the right side of the figure, and rotates around the shaft portions of the fixture 53 with respect to the support member 5 along the arc-shaped grooves 54 and 55 with which the shafts 64 and 65 are respectively engaged. . As a result, the torsion spring 7 is compressed, and the torsion spring 7 generates a force in an outward direction to return to the original state, so that the rail member 9 is pushed and becomes a rotation assist force.

  FIG. 6B shows a rotated state. When the rail member 91 rotates 90 degrees, the upper and lower rails 91 are engaged with the linear portion of the rotation direction guide portion 52 of the support member 5. At the same time, it engages with the linear portion of the rotational direction guide portion 62 of the movable member 6, and at the same time, the wall of the rotational direction guide portion 52 of the support member 5 hits the end surface of the rail 91 as shown in FIG. Stops.

At this time, the movable member 6 returns to the original position by the force of the torsion spring 7 because the linear portion of the rotational direction guide portion 62 is not pushed by the rail 91.
After the rotation, the rail member 9 is held by the linear portion of the rotational direction guide portion 52 of the support member 5 and the linear portion of the rotational direction guide portion 62 of the movable member 6, so that the strength is high and the backlash is small. .

  FIG. 9 shows the rotated state as seen from the back side. The rail member 9 can be seen on the back side of the second casing 2 on the left and right sides of the first casing 1, and a guide hole as in the conventional case is shown. Because it is not exposed, it looks good.

  FIGS. 10A and 10B are views of the rear side when viewed from the left and right sides in a rotated state. Both the left and right sides of the rail member 9 on the rear side of the second casing 2 and the first casing 1 are shown. Since the wall portion of the slide direction guide portion 51 of the support member 5 and the wall portion of the slide direction guide portion 61 of the movable member 6 are located between them and the internal structure is not exposed, the appearance is good.

  Next, FIG. 11 shows an example of the wiring 10 on the first housing 1 side provided with the support member 5, FIG. 11A is in a slide closed state together with the rail 91, and FIG. The state, FIG. 11 (c) shows the same rotated state.

  As shown in the drawing, the wiring 10 by the coaxial line is led out from the wiring through hole 56 of the support member 5 fixed to the upper surface of the first housing 1. The wiring 10 is disposed outside the fixture 71 that attaches the torsion spring 7 to the movable member 6 and inside the shaft 64 that engages the arcuate groove 54 on the right side of the support member 5 in the drawing.
