By engaging with the groove 7, the slider portion 8 is prevented from coming out of the guide groove 7. The reference symbol 8b is a mounting hole for the mounting screws 4 and 4.

  The configuration of the tilt hinge portions 9 and 9 constituting the tilt mechanism 3 is also only symmetrical, and the configuration is the same, so only one of them will be described. In particular, as shown in FIGS. 5 and 6, what is indicated by an instruction symbol 10 is an attachment member, and this attachment member 10 is attached to the rear end side of the upper surface of the first housing 1 at a predetermined interval. The board portion 10a is attached to the first housing 1 with mounting screws (not shown), and the side plates 10b and 10b are raised from both sides of the board portion 10a. Preferably, a metal plate such as SUS is pressed. Made by processing. The side plates 10b and 10b are provided with shaft support holes 10c and 10c having a common shaft core, and the side plates 10b and 10b are, for example, pressed at diagonal positions inside the side plates 10b and 10b with the shaft support holes 10c and 10c interposed therebetween. Thus, the first cam portions 13 and 13 are provided by providing the recesses 13a and 13a, respectively.

  A hinge pin 12 is inserted into and attached to the shaft support holes 10c and 10c, and an attachment portion 12a having a deformed outer diameter is formed at a portion where the hinge pin 12 passes through one side plate 10b and protrudes outward. The support member 11 is attached to the attachment portion 12a so as to rotate together with the hinge pin 12 in a cantilever manner.

  The support member 11 is preferably made by pressing a metal plate such as SUS, but is not limited to this, and may be a forged product, for example. As shown in FIGS. 5 to 7, the support member 11 has a substantially L-shaped cross section, and has a mounting portion 11a having a deformed mounting hole 11c attached to the hinge pin 12, and is bent in a direction perpendicular to the mounting portion 11a. The slider portion 8 described above is attached to the support portion 11b with mounting screws 4 and 4 as shown in FIGS.

The deformation shaft portion 12c provided on the other end side and the caulking portion 12d provided on the other end side are attached. The attachment portion 11a of the support member 11 is attached to the attachment portion 12a, and the deformation shaft portion 12c is attached to the side plate 10b of the attachment member 10. 10b is rotatably supported in shaft support holes 10c and 10c provided in 10b. The attachment portion 12a of the hinge pin 12 inserted into the deformation attachment hole 11c provided in the attachment portion 11a of the support member 11 is fixed to the deformation attachment hole 11c by caulking the end portion thereof. It is not limited to the above, and other means such as an E-ring or a nut may be used. The caulking portion 12d can also be formed of a nut.

  A rotation control means 14 is provided between the attachment member 10 and the support member 11. As shown in FIGS. 5 and 6, the friction torque generating means 20 of the rotation control means 14 is a flange provided on the hinge pin 12 when the support member 11 is rotatably connected to the mounting member 10 by the hinge pin 12. Between the portion 12b and the outer side of one side plate 10b of the mounting member 10, a resin or brass-like material such as a resin or brass arranged by inserting the deformation shaft portion 12c of the hinge pin 12 through the deformation insertion hole 15a provided in the center portion. A friction washer 15 having wear and a cam disposed by inserting the deformed shaft portion 12c of the hinge pin 12 through the deformed insertion holes 16a and 16a provided in the axial direction of the central portion of the side plates 10b and 10b of the mounting member 10. Elasticity comprising a plate 16 and 16 and a compression spring elastically wound around the hinge pin 12 between the cam plates 16 and 16 And stage 18, in is configured. If the elastic means is configured in this way, there is an advantage that the elasticity can be used more effectively. Further, as shown in FIG. 8, the cam plates 16, 16 are each a second cam portion composed of convex portions 16 b, 16 b with the deformation insertion holes 16 a, 16 a sandwiched on the side facing the first cam portions 13, 13. 17 and 17 are provided. Furthermore, a flat washer 19 provided between the side plate 10 b and the caulking portion 12 d of the hinge pin 12 may be added as a constituent member of the friction torque generating means 20.

  In the friction torque, when the end portion of the hinge pin 12 is caulked to form the caulking portion 12d, the friction washer 15 is pressed between the one side plate 10b of the mounting member 10 and the flange portion 12b, and the flat washer 19 is The crimping portion 12d and the other side plate 10b are pressed against each other, and the cam plates 16 and 16 are pressed against the inner side of the side plates 10b and 10b of the mounting member 10 by the elastic means 18. This occurs when the support member 11 is rotated. With this configuration, the necessary torque can be generated even with a small diameter.

  As shown in FIGS. 5, 6, and 8, the click stop means 21 includes the first cam portions 13 and 13 including the concave portions 13 a and 13 a provided in the side plates 10 b and 10 b of the mounting member 10, and the cam plate. 16 and 16 and the second cam portions 17 and 17 formed of the convex portions 16b and 16b. The convex portions 16b and 16b of the cam plates 16 and 16 are the concave portions 13a provided on the side plates 10b and 10b, respectively. While the friction torque is generated while escaped from 13a, the click is stopped when the convex portions 16b and 16b fall into the concave portions 13a and 13a. This click stop occurs when the second housing 2 is at an angle of about 60 ° with respect to the rear side of the first housing 1 in the embodiment, but is not limited to this angle. Further, depending on how the concave portions 13a and 13a and the convex portions 16b and 16b are provided, the click can be stopped at a plurality of angles. The concave portions 13a and 13a and the convex portions 16b and 16b may be provided in reverse.

  The cam plates 16 and 16 can be a single plate, and the elastic means 18 contributes to the generation of friction torque by the rotation control means and further improvement of the click stop function when configured as in the embodiment. However, other spring washers and disc springs can be used. As shown in the figure, the convex portions 16b and 16b of the second cam portion 17 generate a stronger friction torque if their upper surfaces are made flat, but they may be round. Further, the click stopping means 21 may be omitted and only the friction torque generating means 20 may be used. Furthermore, if the configurations of the friction torque generating means 20 and the click stopping means 21 are configured as in the embodiment, the necessary friction torque can be generated with a small configuration without overworking the configuration, and a stable click can be achieved. Although the stop function can be exhibited, the present invention is not limited to this, and one stop may be provided on one side, and various other known ones can be applied. Furthermore, although the support member 11 is a cantilever type, it is also possible to connect this to the attachment member 10 in a both-end support type.

  The operation of the switchgear B according to the present invention will be described below.

  First, in the closed state in which the first casing 1 and the second casing 2 shown in FIG. 1A of the portable information device A are overlapped with each other, the opening / closing device B has the same configuration as that of FIG. In the state shown in (b), the positions of the slider portions 8 and 8 are at the positions of the start ends of the guide grooves 7 and 7 of the slide rail members 6 and 6 of the slide mechanism 5. Even if the rear end side of the second housing 2 is held in this closed position and the first housing 1 is to be raised from the rear side, the front end portion of the second housing 2 is the first housing. It is impossible to get up by hitting the upper surface of the body 1. This is the same even if the front side of the second housing 2 is held and the first housing 1 is raised from the front side.

  In this closed state, it goes without saying that if any click stopping means or engaging means is provided between the slider portions 8, 8 and the slide rail members 6, 6, the closed state becomes stable.

  Next, when the second casing 2 is pushed to the rear side of the first casing 1 from this closed state, or the first casing 1 is pulled toward the front side with respect to the second casing 2. Since the slide rail members 6 and 6 are guided and slid by the slider portions 8 and 8, the second housing 2 and the first housing 1 slide relatively, and the upper surface of the first housing 1 is It is exposed and becomes an open state as shown in FIG. This open state is stopped when the slider portions 8 and 8 reach the end portions of the guide grooves 7 and 7, as shown in FIG. In this manner, the keyboard unit 1a on the first housing 1 can be operated.

  If the rear end side of the second casing 2 is pulled upward from this opened state, the concave groove 1b that allows the lower end of the front side to escape at the sliding position of the second casing 2 is particularly shown in FIGS. As shown in FIGS. 4 and 9, since it is provided on the upper surface of the first housing 1, it can be caused, and the support member 11 rotates together with the hinge pin 12, so that the second housing 2 is moved to the first housing 1. You will get up against body 1. This cause is referred to herein as “getting up” or “standing up”. This rising (standing) angle is 60 ° in the embodiment. As shown in FIG. 1C, the recesses 13a and 13a of the first cam portion 13 of the click stopping means 21 and the protrusions of the second cam portion 17 when the angle is 60 ° from the rear side of the first housing 1. Since the parts 16b and 16b are engaged, the click is stopped at this position. The state of the switching device B in this state is shown in FIG. Of course, it is possible to get up to an angle of 90 °, for example. However, 60 ° is selected as the angle at which the display unit 2b is most easily viewed. As a means for enabling the second housing 2 to be raised with respect to the first housing 1, the configuration is complicated, but a rising allowance device other than the groove 1b may be used. If the second housing 2 slides with respect to the first housing 1 and is fully opened, the rising permission means can be configured to permit rotation of the support member 11 relative to the mounting member 10. There is no limitation. In addition, the method of forming the concave groove 1b is configured to reach both end portions of the first housing 1 in the drawing, but the both end portions on the near side of the second housing 2 are rounded to take a rounded shape. Then, it does not need to be set as the structure which reaches the both ends of the 1st housing | casing 1. FIG.

  If it is possible to raise the second casing 2 during the sliding of the second casing 2 with respect to the first casing 1, in order to get up in the middle, it is a recess that allows the lower end of the second casing 2 to escape. Since the groove 1b is not on the first housing 1 side, this is impossible.

  Of course, the raising of the second casing 2 relative to the first casing 1 may be performed by other means although the configuration is complicated.

  When the second casing 2 is raised, when the upper part of the upper surface is pushed to the rear side, the support member 11 is rotated via the hinge pin 12 to return to the original parallel state in the fully opened state. If the second housing 2 can be slid to the near side when the second housing 2 is raised with respect to the first housing 1, the lower end on the near side of the second housing 2 is the first housing when the second housing 2 is raised. Since it enters the concave groove 1b of the body 1, sliding toward the near side is rejected.

  When the second casing 2 is raised as described above, and when the second casing 2 is returned to the parallel state in the original fully opened state, the friction torque generating means 20 generates the friction torque to generate the second torque. It is possible to stop the housing 2 in a free stop with respect to the first housing 1.

  The second housing 2 returned from the rising state to the original parallel state is slid to return to the original position by pulling it toward the front side or pushing the first housing 1 backward. ). In the slide mechanism 5, although not shown in the figure, for example, it is possible to arbitrarily add semi-automatic means having a known configuration using elastic means such as a snake spring, a push spring, or a pull spring. .

  FIG. 10 shows another embodiment of the slide mechanism, which is disassembled from the reverse direction of the state in use. The slide rail member 26 of the slide mechanism 25 according to this embodiment is made of stainless steel for a spring and has a case shape with an integrated structure having a substantially planar shape. Two are used as in the previous embodiment, but only one is shown. As shown in the drawing, the slide rail member 26 is composed of a slide rail member 26 composed of a case-like rail main body in which a lock plate 26b and a slide cover 26c are engaged and fixed facing each other. Raised portions 26d and 26d are provided on both inner ends. The slide cover 26c is provided with guide grooves 26e that reach the both end portions in the longitudinal direction, and a plurality of mounting portions 26f that protrude from the slide cover 26c are connected to the second casing 2 as in the previous embodiment. It is fixed to the back with a mounting screw. The lock plate 26b and the slide cover 26c are engaged and fixed by engaging a plurality of locking protrusions 26g provided around the lock plate 26b with locking holes 26h provided in the slide cover 26c. The locking protrusion and the locking hole may be reversed, and the fixing means is not limited to that of this embodiment.

  The slider portion 28 slidably engaged with the slide rail member 26 formed of the rail portion main body is accommodated in the guide rail 28a fitted in the guide groove 26e and the slide rail member 26 formed of the rail portion main body. The slider 28b has a spring property, and elastic protrusions 28c and 28c are provided at both ends of the slider 28b. The elastic protrusions 28c and 28c perform a locking function by engaging with the raised portions 26d and 26d during the sliding operation of the slider 28b. Reference symbols 28e, 28e and 28f, 28f are mounting holes for attaching the spacers 28d, 28d. The spacers 28d and 28d are provided with female screw holes 28g and 28g. One end portions of the spacers 28d and 28d are inserted into the mounting holes 28e and 28e of the slider 28b and fixed by caulking, and the other end portions of the guide member 28a are fixed. It is inserted into the mounting holes 28f, 28f, and then the support member 11 is overlapped, and then the whole is fixed by mounting screws 29, 29. The configuration of the slider portion 28 is not limited to that of the embodiment, and the guide member 28a may be integrated with the support member 11, for example, or the slider 28b may be replaced by a pin attached to the support member 11. Also good.

  When implemented as described above, there is an advantage that the sliding of the slider 28b with respect to the slide rail member 26 formed of the rail portion main body becomes smoother and smoother. Note that the lubricant is used for the sliding portion as necessary.

  As another embodiment, each of the tilt mechanism and the slide mechanism includes a pair of tilt hinge portions and a slide rail member. However, if necessary, the tilt hinge portion and the slide rail member can be integrated.

  As can be understood from the above description, the switchgear according to the present invention has a simple configuration, and in particular, a first casing that constitutes a portable information device such as a small personal computer, a mobile phone, and a portable terminal.
