  The locking means 6 is provided on the front side of the front cover 2b on the near side of the first member 2 so as to be slidable from the outside. For example, two N poles showing different magnetic poles of N and S A pair of movable magnets 20 and 20 composed of a magnet 19a and an S-pole magnet 19b are mounted and fixed in parallel with a predetermined interval therebetween, and a guide groove provided below the surface cover 2b of the first member 2 2c, a movable magnet member 19 that is housed together with the movable magnets 20 and 20 and a surface cover 3b on the display unit 3a side of the second member 3 so as to be hidden from the front surface with a predetermined interval. The fixed positions of the fixed magnets 21 and 21 are, for example, in the closed state of the first member 2 and the second member 3. The movable magnet attached to the movable magnet member 19 N pole magnet 19a, which is one of 0, 20, are determined so as to 19a facing. Needless to say, the magnetic poles of the fixed magnets 21 and 21 differ depending on the arrangement of the N-pole magnets 19a and 19a and the S-pole magnets 19b and 19b constituting the movable magnets 20 and 20, respectively.

  The operating means 8 includes an attachment member 22 attached at a position facing the hinge portion 5B of the hinge means 5 on the side of the first member 2, and the rotation member 13 into the insertion hole 22a provided in the attachment member 22. A push button member 23 slidably mounted so as to oppose, and a flat surface rotatably mounted in the horizontal direction by a support pin 25 with the operating portion 24a facing the push button member 23 and the rotation member 13 An approximately L-shaped first lever member 24, a first connecting member 27 having one end connected to a turning portion 24 b of the first lever member 24 via a connecting pin 26, and the first connecting member 27 The operating portion 31a is connected to the other end via a connecting pin 28, and the second lever member 31 provided so as to be rotatable in the horizontal direction by the support pin 29, and the swivel portion 31b of the second lever member 31 One end is connected via a connecting pin 32 The other end portion of the movable member 19 is connected to the end portion of the movable magnet member 19 via a connecting pin 34, and the lower side of the surface cover 2 b at the right end portion of the first member 2. It is installed in a step portion 2d provided so as not to be visible from the outside. 4 to 6 and FIG. 8, the reference symbol 13c indicates a cap member that closes the first lever member 24 side of the rotating member 13, and the reference symbol 13d indicates the cap member 13c. It is a protrusion for inserting and attaching to the deformation insertion hole 13a of the rotation member 13. The cap member 13c may be omitted by closing the cap member 13c side of the rotating member 13.

  As described above, the operation means 8 is provided collectively on the right side of the first member 2, and the movable magnet member 19 is attached to the groove portion 3 c provided on the front side of the first member 2 so as to be slidable in the left-right direction. It has been. Further, as described above, the operating means 8 is installed below the surface cover 2b of the first member 2, and is not exposed to the outside.

  Next, functions and effects of the above-described embodiment of the present invention will be described. As shown in FIG. 1, in the closed state in which the first member 2 and the second member 3 are closed, as shown in FIG. Among the movable magnets 20 and 20 of the movable magnet member 19 of the lock means 6 provided, for example, those of the N-pole magnets 19a and 19a and the fixed magnets 21 and 21 of the S-pole provided on the second member 3 side are not. Since the surface cover 2b and the surface cover 3b, which are magnetic pole materials, are opposed to each other, the first member 2 and the second member 3 are locked in a closed state by the magnetic attractive force of both.

  Therefore, when the push button member 23 is pushed to open the second member 3 with respect to the first member 2, as shown in FIGS. 5 and 12, the operating portion 24a of the first lever member 24 is caused by this pushing force. Turns counterclockwise with the support pin 25 as a fulcrum, and slides the rotating member 13 to the left in the figure against the elasticity of the first elastic means 18.

  At the same time, the second lever member 31 pivots about the support pin 29 via the first connecting member 27 as the first lever member 24 pivots, and the movable magnet member 19 moves to the right side in the drawing via the second connecting member 33. Therefore, the S-pole fixed magnets 21 and 21 attached to the second member 3 face the S-pole magnets 19b and 19b of the movable magnets 20 and 20 attached to the movable magnet member 19. The second member 3 is slightly opened with respect to the first member 2 by hop-up on the hinge shafts 10 and 14 of the hinge portion 5B and the hinge portion 5B with respect to the first member 2 by the magnetic repulsive force.

  At this time, since the cam portion 13b of the rotating member 13 rotated together with the hinge shaft 14 of the hinge portion 5B engages with the stopper member 17, the second member 3 opened by hopping up is naturally dropped. It is held in a slightly opened state without.

  Since the hop-up operation of the locking unit 6 and the holding operation by the holding unit 7 are performed almost simultaneously, even if the push button member 23 is pushed with the finger and released, the cam portion 13b and the stopper member 17 are engaged. Therefore, the rotating member 13 does not immediately return to the original position due to the elasticity of the second elastic means 30.

  Subsequently, when the second member 3 is opened by placing a hand to open the second member 3 with respect to the first member 2, the second member 3 is opened via the hinge means 5. When it is opened to a predetermined opening angle, the stopper member 17 is disengaged from the cam portion 13b, so that the rotating member 13 returns to the original position by the elasticity of the first elastic means 18, and at this time, the first lever member 24 is moved forward. While rotating in the clockwise direction of the opposite direction, the push button member 23 is pushed by the operating portion 24a to return to the original position. However, this portion can also be pivotally biased so that the first lever member 24 returns to the original position by other means.

  At the same time, the second lever member 31 rotates in the clockwise direction opposite to the previous direction via the first connecting member 27 to return the movable magnet member 19 to the original position. Most of the time, the movable magnet member 19 may be configured to return to the original position by acting an elastic means (not shown).

  As described above, the second member 3 is opened to 180 degrees with respect to the first member 2 as shown in FIG. The opening angle is not limited.

  When the opened second member 3 is closed, it is closed via the hinge means 5, and at this time, the movable magnet member 19, the holding means 7, and the operating means 8 of the lock means 6 are returned to their original positions. Therefore, the S-pole fixed magnets 21 and 21 on the second member 3 side to be closed face the N-pole magnets 19 a and 19 a among the movable magnets 20 and 20 of the movable magnet member 19. However, the second member 3 is locked again by the magnetic attractive force in the closed state with respect to the first member 2.

  As another embodiment, the operating means 8 has an operating lever attached to the movable magnet member, this operating lever protrudes to the side of the first member 2, and the movable magnet member itself slides in one direction. The holding means 7 is provided with a cam portion on the hinge shaft itself, and a stopper member that engages with the cam portion according to the rotation angle of the hinge shaft is rotated and urged in one direction. You can also. This configuration would be more desirable when implemented in a car console box.

  Since the present invention is configured as described above, it is possible to provide a switching device with a hop-up function with a simple configuration so that the lock means is not visible from the outside without any restrictions on the design. The present invention can be suitably used as an opening / closing device for an electronic device such as a personal computer or a portable game machine, and can also be applied as an opening / closing device for an automobile console box.
