  Hereinafter, embodiments of the present application will be described in detail based on specific examples with reference to the accompanying drawings. Since the structure of the notebook computer 3 of the comparative technique described with reference to FIGS. 1 and 2 is not changed, the same components as those of the notebook computer 3 of the comparative technique are denoted by the same reference numerals.

  FIG. 4A shows a closed state of the notebook personal computer 3 to which the opening / closing device 41 of the first embodiment of the present application is attached. The opening / closing device 41 according to the first embodiment includes two hinges 4 provided at positions on both sides of the side 5 portion that connects the main body 1 and the display unit 2. The two hinges 4 in the notebook computer 3 of the comparative technique described in FIG. 1A are attached to the main body 1 so that the hinge rotation shafts 4A coincide with each other.

On the other hand, the hinges 4A of the two hinges 4 in the opening / closing device 41 of the first embodiment of the present application do not coincide with each other, and the axis AX of the hinges 4A is determined by the main body 1 and the display 2. Are provided with a predetermined angle A with respect to the side 5 connecting the two. The angle A is in the range of 2 ° to 4 °. That is, the two hinges 4 are attached to the main body 1 in an inclined state by 2 ° to 4 ° so that the axis AX of the two hinge rotation shafts 4A intersects at the point B on the main body 1. And the rigidity of the housing of the display part 2 is formed lower than the rigidity of the housing of the main body part 1. In order to make the rigidity of the casing of the display unit 2 lower than the rigidity of the casing of the main body 1, a method of lowering the hardness of the material of the casing or a method of reducing the thickness of the casing can be considered.

  For this reason, when the display part 2 of the notebook personal computer 3 is opened with respect to the main body part 1, the display part 2 curves with the main body part 1 side convex. FIG. 4B shows a state in which the display unit 2 of the notebook computer 3 shown in FIG. 4A is opened to a direction perpendicular to the main body unit 1. A convex and curved state is shown. Accordingly, when the display unit 2 is provided with a touch panel, the display unit 2 is curved with the main body unit 1 side projecting, so that it can counter an external force applied from the main body unit 1 side. The display unit 2 is less likely to vibrate by operation.

  Here, in the notebook personal computer 3 including the opening / closing device 41 of the first embodiment including the two hinges 4, when the display unit 2 is opened with respect to the main unit 1, the display unit 2 makes the main unit 1 side convex. The principle of bending will be described using an open / close model 10 for a folding article. FIG. 5A is a plan view of a folding article opening / closing model 10 to which the opening / closing device 41 of the first embodiment is attached, and FIG. 5B is a side view of FIG. 5A. The folding article opening / closing model 10 includes a main body portion 11 and two rectangular plate-like opening / closing members 12, and the opening / closing member 12 is connected to the main body portion 11 by a hinge 4 on one side in the short direction. ing. The length of the side in the longitudinal direction of the opening / closing member 12 is equal to the length of the side in the short direction of the main body 11. The two hinges 4 are attached to both sides of one side 15 on the upper surface of the main body 11 in a state inclined by a predetermined angle A with respect to the side 15.

  FIG. 5C is an enlarged view showing a state where the two opening / closing members 12 are attached to the main body 11 by the two hinges 4. Actually, the angle A when the two hinges 4 are attached to be inclined with respect to the side 15 is in the range of 2 ° to 4 °. It is exaggerated. The hinge 4 has a first attachment portion 4B attached to the main body portion 11 with a screw 7 and a second attachment portion 4C attached to the opening / closing member 12 with the screw 7. The first attachment portion 4B and the second attachment portion 4C are hinges. The rotary shaft 4A is rotatably connected.

  FIG. 6A shows a state in which the two opening / closing members 12 of the opening / closing model 10 shown in FIG. 5A are closed. The hinge rotation shaft 4 </ b> A of the opening / closing device 41 is attached to be inclined at a predetermined angle A with respect to the side 15 of the main body 11 (the state in which the predetermined angle A is inclined with respect to a line L parallel to the side 15 is shown in the drawing. Have been). When the opening / closing member 12 is closed, the two opening / closing members 12 are not at an angle to each other, and the upper and lower surfaces of the two opening / closing members 12 are on the same plane. Further, the side surface 12S of the opening / closing member 12 is on the same plane as the side surface 11S of the main body 11. At this time, a line P that is parallel to the distal end and is separated from the distal ends of the two opening / closing members 12 by the same distance is on a straight line.

  FIG. 6B shows a state where the two opening / closing members 12 are slightly opened from the state shown in FIG. It is assumed that the opening angles of the two opening / closing members 12 are the same. Since the rotation shafts 4A of the two hinges 4 are inclined at a predetermined angle A in different directions with respect to the side 15, when the two opening / closing members 12 are opened, the two opening / closing members 12 have an angle with each other. Thus, the upper and lower surfaces of the two opening / closing members 12 are not positioned on the same plane.

  At this time, the hinge rotation shaft 4A of the opening / closing device 41 is attached to the side 15 of the main body portion 11 at a predetermined angle A, so that the parallel lines P separated from the tip ends of the two opening / closing members 12 by the same distance. Intersect. FIG. 6C shows a state where the two opening / closing members 12 shown in FIG. 6B are further opened. It is assumed that the opening angles of the two opening / closing members 12 are the same. Even in this state, lines P that are separated from the tip ends of the two opening / closing members 12 by the same distance and that are parallel to the tip portions intersect.

  FIG. 7A shows a state where the two opening / closing members 12 shown in FIG. 6C are opened to a position perpendicular to the main body 11. Since the hinge rotation shaft 4A of the opening / closing device 41 is attached to be inclined at a predetermined angle A with respect to the side 15 of the body portion 11, in this state, the distal end separated from the distal ends of the two opening / closing members 12 by the same distance. The line P parallel to the portion intersects at a predetermined angle 2A.

Therefore, as shown in FIG. 7 (b), when the flexible housing 13 is present between the two opening / closing members 12 shown in FIG. 7 (a), the housing 13 is the main body portion. It is deformed to bend (curve) with the 11 side convex. Therefore, it can be seen that the casing formed integrally with the two opening / closing members 12 and the flexible casing 13 is curved with the main body portion 11 side being convex.

  However, as can be seen from FIGS. 7A and 7B, when the opening / closing member 12 is opened from the main body 11, the distance between the opening / closing members 12 on the side closer to the main body 11 is larger. It is longer than the distance between the opening / closing members 12 on the distal end side away from. For this reason, even in the case 13 with flexibility in the portion between the two opening / closing members 12, the deformation amount differs between the main body 11 side and the distal end side, and unnatural deformation may occur. For this reason, the inclination angle A with respect to the side 15 of the hinge 4 cannot be increased too much.

  Therefore, in the opening / closing device 42 of the second embodiment of the present application, the hinge 8 is provided with a degree of freedom between the opening / closing member 12 and the second mounting portion 4C of the hinge 4 of the first embodiment. This will be described with reference to FIGS. 8 and 9. FIG. 8A shows a foldable article in which the two hinges 4 of the opening / closing device 41 of the first embodiment in the foldable article opening / closing model 10 shown in FIG. An open / close model 10A is shown.

  Also in the opening / closing device 42 of the second embodiment, in reality, the angle A when the two hinges 8 are attached to be inclined with respect to the side 15 is in the range of 2 ° to 4 °. The angle A is exaggerated for easy understanding. The hinge 8 includes a first attachment portion 8B attached to the main body portion 11 with a screw 7 and a second attachment portion 8C attached to the opening / closing member 12 with the rotary shaft 9, and the first attachment portion 8B and the second attachment portion 8C. Are rotatably connected by a hinge rotation shaft 8A. The rotating shaft 9 is screwed to the opening / closing member 12 through a through hole 8H provided in the second mounting portion 8C and having an inner diameter slightly larger than the diameter of the rotating shaft 9.

  As a result, as shown in FIG. 8B, the first attachment portion 8B of the hinge 8 is fixed to the main body portion 11, but the second attachment portion 8C is attached to the opening / closing member 12 by the rotating shaft 9. Therefore, the opening / closing member 12 is rotatable with respect to the second mounting portion 8C. That is, in the opening / closing device 42 of the second embodiment, as shown in FIG. 9, since there is a degree of freedom between the opening / closing member 12 and the hinge 8, the opening / closing member 12 is moved to a position perpendicular to the main body 11. When opened, the base of the opening and closing member 12 can rotate relative to the hinge 8.

  In the first embodiment shown in FIGS. 7A and 7B, when the opening / closing member 12 is opened at a right angle from the main body 11, the distance between the opening / closing members 12 on the side closer to the main body 11 is longer. However, it was longer than the distance between the opening-and-closing members 12 on the distal end side away from the main body 11. On the other hand, in the second embodiment, when the opening / closing member 12 is opened at a right angle from the main body 11, the base of the opening / closing member 12 can be rotated with respect to the hinge 8, so that the opening / closing member on the distal end side away from the main body 11. The distance between 12 can be made the same as the distance between the opening and closing members 12 on the side close to the main body 11.

  As a result, when the flexible housing 13 is provided between the two opening / closing members 12, unnatural deformation on the main body 11 side of the flexible housing 13 can be reduced. The flexible housing 13 can be curved smoothly. For this reason, the inclination angle with respect to the side 15 of the hinge 8 can be increased as compared with the first embodiment.

FIG. 10A is a perspective view showing a closed state of the notebook personal computer 3 to which the opening / closing device 42 of the second embodiment of the present application is attached, and FIG. 11A is a plan view of FIG. Fig. 11 (b) is a side view of Fig. 11 (a). In the state shown in these drawings, the display unit 2 is flat with respect to the main body unit 1, and the display unit 2 exactly overlaps the main body unit 1. The two hinges 8 of the opening / closing device 42 of the second embodiment are attached between the main body 1 and the display unit 2 while being inclined at a predetermined angle A with respect to one side 5 of the notebook computer 3. Yes. The rigidity of the housing of the display unit 2 is formed to be lower than the rigidity of the housing of the main body unit 1 in the same manner as the notebook computer 3 to which the opening / closing device 41 of the first embodiment is attached.

  10B is a perspective view showing a state in which the display unit 2 of the notebook personal computer 3 shown in FIG. 10A is opened to a direction perpendicular to the main body unit 1, and FIG. 10 (b) is a plan view, and FIG. 11 (d) is a side view in which a part of FIG. 11 (c) is omitted. When the display unit 3 is opened to a right angle with respect to the main body unit 1, the display unit 2 is slightly curved with the main body unit 1 side convex. Since the lower part of the display unit 2 rotates with respect to the hinge 8 in the opening / closing device 42 of the second embodiment, there is no unnatural deformation, and a curve Q shown in FIGS. 10 (b) and 11 (c). In addition, the display unit 2 is smoothly curved.

  Thus, when the display unit 2 of the notebook personal computer 3 is opened with respect to the main body unit 1 and the display unit 2 is curved with the main body unit 1 projecting, the touch when the display unit 2 is provided with a touch panel is touched. The display unit 2 is unlikely to vibrate in response to the operation. This is because the display unit 2 is curved with the main body unit 1 side convex so that the strength against external force applied from the main body unit 1 side can be improved, and the display unit 2 is less likely to vibrate by a touch operation. It is. At the same time, the friction of the hinge rotation shaft 8A increases due to the moment, and the shaking of the display unit 2 can be suppressed.

  12A shows a closed state of the notebook personal computer 3 to which the opening / closing device 43 of the third embodiment of the present application is attached, and FIG. 12B is a side view of FIG. It is. The difference between the opening / closing device 43 of the third embodiment and the opening / closing device 42 of the second embodiment is the direction of the hinges 8 attached to both sides of the upper surface of the main body 1. As shown in FIG. 11A, the two hinges 8 of the opening / closing device 42 of the second embodiment are such that the axis AX of the hinge rotation shaft 8A is on the side 5 connecting the main body 1 and the display 2. On the other hand, it has a predetermined angle A and intersects at a point B on the main body 1.

On the other hand, the two hinges 8 of the opening / closing device 43 of the third embodiment are such that the axis AX of the hinge rotation shaft 8A is at a predetermined angle with respect to the side 5 connecting the main body 1 and the display 2. The points provided with A are the same, but intersect at a point C outside the main body 1. The size of the predetermined angle A may be 2 ° to 4 °, similar to the opening / closing device 42 of the second embodiment. That is, in a state where the two hinges 8 are inclined by 2 ° to 4 ° with respect to the side 5 of the main body 1 so that the axis AX of the two hinge rotation shafts 8A intersects at a point C outside the main body 1. It is attached. And the rigidity of the housing of the display part 2 is formed lower than the rigidity of the housing of the main body part 1.

  12C and 12D show a state in which the display unit 2 of the notebook personal computer 3 shown in FIGS. 12A and 12B is opened to a direction perpendicular to the main body unit 1. In the third embodiment, similarly to the second embodiment, the display unit 2 and the hinge 8 are connected and connected via a rotating shaft. For this reason, when the display unit 3 is opened up to a right angle with respect to the main body unit 1, the display unit 2 is smoothly curved with the main body unit 1 side being concave. That is, since the lower part of the display unit 2 is rotating with respect to the hinge 8 in the opening / closing device 43 of the third embodiment, the display unit 2 is smooth as shown by a curve R shown in FIG. It is curved.

  When the display unit 2 of the notebook computer 3 is opened with respect to the main unit 1, the display unit 2 is input from the opposite side of the main unit 1 in the notebook computer 3 that is curved with the main unit 1 side being concave. There is resistance against external forces. That is, the display unit 2 is unlikely to vibrate in response to a touch operation when the touch panel is provided outside the main unit 1 of the display unit 2. This is because the display unit 2 is curved outward with the main body unit 1 side being concave, so that the strength can be improved against an external force applied from the outside of the main body unit 1, and the display unit 2 vibrates by a touch operation. Because it is difficult to do. At the same time, the friction of the hinge rotation shaft 8A increases due to the moment, and the shaking of the display unit 2 can be suppressed.

  The opening / closing devices 41, 42, 43 as described above can be applied as opening / closing devices for thin laptop computers, game machines, etc., and for example, when opened, one surface is curved to make the display stand out. It can be applied to articles for use. Fig.13 (a) shows the open state of the articles | goods 30 to which the switchgear (not shown) of the 2nd Example of this application was attached. In this example, one display surface 31 is curved with the front protruding. Moreover, FIG.13 (b) shows the open state of the articles | goods 50 to which the opening / closing apparatus (not shown) of the 2nd Example of this application was attached. In this example, one display surface 51 is curved with a concave front. As such articles 30 and 50, a photo stand or a stand signboard can be considered. Any article can emphasize the content displayed on the curved surface. Further, the warp shape increases the rigidity, and the strength of the signboard or the like can be improved.
