The note book is connected to the rear of the upper surface of the first frame body so that the second frame body is rotatably connected through a hinge device, and the surface having the display of the second frame body is closely adhered to the upper surface of the first frame body keyboard. At the same time, it is possible to expose the keyboard and display by opening the display from an overlapping state. In other words, since the keyboard and the display are not exposed in the closed state in which the first frame and the second frame overlap with each other without being used, in order to expose the keyboard and the display, for example, with one hand. By fixing the first frame and holding the second frame with the other hand, the second frame is rotated through the hinge device with respect to the first frame to expose the keyboard and the display, thereby exposing the keyboard and display to an open state. This makes it possible to use a notebook. As the hinge device, the first frame body and the second frame body are rotatably connected to each other, and the second frame body does not naturally close to the first frame body while the first frame body and the second frame body are open. It is proposed that it can hold | maintain in state. As the known document, one described in Japanese Patent Laid-Open No. 2003-120650 is known.

It is preferable to provide the cam B protrusion part 75 which generate | occur | produces a frictional force in between.

The 76 is coupled to the cam mounting hole 36 of the mounting member 3 so that the cam A body 71 is attached to the mounting member 3.

As shown in FIGS. 2-8 and 12, the cam body 72 is formed in the disk shape of diameter substantially the same as the cam A body 71, for example.

The friction force applying means 73 is not particularly limited, and is, for example, a ring-shaped leaf spring 78 or the like. The number of the leaf springs 78 is not particularly limited to one, two or more, for example, preferably four. These leaf springs 78 are provided around the axis of the hinge shaft 2 so as to contact the second surface on the side opposite to the contact surface 72b to which the cam A body 71 of the cam body 72 contacts. The washer 79 is provided in the hinge shaft 2 of the surface on the opposite side to the cam body 72 of these leaf springs, ie, the 2nd end part of the hinge shaft 2. The leaf spring 78 is attached to the hinge shaft 2 by caulking or riveting the 2nd end part of the hinge shaft 2 which protrudes from this washer 79. As shown in FIG.

The cam A protrusion 74 and the cam B protrusion 75 which generate | occur | produce the said friction force and make it into the free stop state are provided. These cam A protrusions 74 and cam B protrusions 75 are formed to protrude in a projecting shape from the contact surface 7lb of the cam A body 71 and the contact surface 72b of the cam body 72, respectively, and are rotated. When the angle is in the range of 45 degrees to 180 degrees, the front end face of the cam A protrusion 74 and the front end face of the cam B protrusion 75 are in surface contact with each other, and the hinge shaft 2 and the mounting member 3 are in contact with each other. Friction force is generated.

As shown in FIG. 11, the cam A protrusion 74 is formed in the contact surface 7lb of the cam A body 71 in circular arc shape centering on the hinge shaft 2 (through hole 71a). Preferably comprises two first cam A projections 74a and a second cam A projection 74b. These first cam A protrusions 74a and the second cam A protrusions 74b are circular arcs of different diameters, have a flat end face, and are formed in substantially the same height, and at the same time, the hinge shaft 2 It is formed in the position which acted centering on the through-hole 71a. The diameter of the 1st cam A projection part 74a is formed in the dimension smaller than the diameter of the 2nd cam A projection part 74b, for example. It is preferable that both ends of the first cam A protrusion 74a in the arc direction and both ends of the second cam A protrusion 74b in the arc direction are inclined, respectively.

As shown in FIG. 12, the cam B protrusions 75 are formed on the tip end surface of the cam B protrusions 75 in an arc shape with the center of the hinge shaft 2 (through-hole 72a) as the center. It is preferable that the first cam B protrusions 75a and the second cam B protrusions 75b are provided. The first cam B protrusions 75a and the second cam B protrusions 75b are circular arcs of different diameters, have a flat end surface, and have substantially the same height, and the hinge shaft 2 ( It is formed in a position facing the through coupling hole 72a.

The diameter of the 2nd cam B protrusion part 75b is formed in the substantially same dimension as the diameter of the 2nd cam A protrusion part 74b. Both ends of the first cam B protrusion 75a in the arc direction and both ends of the second cam B protrusion 75b in the arc direction are preferably formed to be inclined.

In this manner, when the rotation angle is in the range of 45 degrees to 180 degrees, the front end surface of the first cam A protrusion 74a and the front end surface of the first cam B protrusion 75a are in surface contact with each other and the second cam A is in contact with each other. The front end face of the protrusion 74b and the front end face of the second cam B protrusion 75b are in surface contact with each other, and thus, between the hinge shaft 2 and the installation member 3, that is, the first frame body 11 and the second body. It is comprised so that the friction force which can be in the state of a free stop will generate | occur | produce between the frames 12. As shown in FIG. In addition, when the rotation angle is in the range of 0 degrees to 45 degrees, the front end surface of the first cam A projection 74a and the front end surface of the second cam A projection 74b are the contact surfaces 72b of the cam body 72 ( While contacting the surface of the first cam projections 75a and the second cam projections 75b, the front end face of the first cam projections 75a and the line of the second cam projections 75b The cross section is in surface contact with the contact surface 7lb (the surfaces other than the first cam A projection 74a and the second cam A projection 74ｂ) of the cam A body 71, and at this time, the hinge shaft 2 It is comprised so that friction force which may be in the state of a free stop does not generate | occur | produce between the installation members 3.

Next, the operation of the hinge device 1 and the portable device 10 according to the present invention will be described.

In a normal state in which the portable device 10 is not used, the first frame body 11 and the second frame body 12 are in a closed state overlapping each other. At this time, as shown in FIG. 5, the contact portion 55 of the slider member 52 contacts one inclined surface of the cam protrusion 54 so that the support member 4 is pressed against the mounting member 3. Since the working force is applied in the closing direction by 56, the first frame body 11 and the second frame body 12 are maintained in the closed state overlapping each other. In this way, the first frame body 11 and the second frame body 12 are kept in the closed state, so that a latch mechanism or the like for fixing the first frame body 11 and the second frame body 12 in the closed state is unnecessary. I can do it. As a result, the fixed state releasing operation for releasing the fixed state when opening the first frame body 11 and the second frame body 12 is unnecessary.

In the case of using the portable device 10, for example, a force is applied to the second frame body 12 so that the second frame body 12 rotates the hinge shaft 2 about the axis relative to the first frame body 11. Let's do it. When the rotation angle is less than 0 degrees to 15 degrees, the second frame 12 is moved to the first member 12 so that the slider member 52 can be moved in the mounting member 3 against the force of the compression spring 56. It rotates with respect to the frame 11. When the rotation angle is 15 degrees and exceeds 15 degrees, as shown in FIG. 6, the contact portion 55 of the slider member 52 slides the tip portion from one inclined surface of the cam protrusion 54 to reach the other inclined surface. Therefore, the second frame body 12 automatically rotates with respect to the first frame body 11 at a rotational angle of 45 degrees due to the action force (elastic force) of the compression spring 56.

As shown in FIG. 7, the second frame 12 having a rotational angle of 45 degrees is applied to the second frame 12 such that the hinge shaft 2 is rotated more axially with respect to the first frame 11. To act. Then, the first cam A projection 74a and the first cam B projection 75a are lifted up against the action force of the leaf spring 78, so that the front end surface and the first cam B projection of the first cam A projection 74a are lifted. While the front end surfaces of 75a make sliding contact while being in surface contact with each other, the second cam A protrusion 74b and the second cam B protrusion 75b are lifted up to each other, and the front end surface of the second cam A protrusion 74b is formed. The front end surfaces of the second cam B protrusion 75b are in sliding contact with each other. This state is performed in the range of 180 degree after turning angle exceeds 45 degree | times.

In this surface contact state, when the rotation of the second frame body 12 is stopped by the action force of the leaf spring 78, the front end surface of the first cam A projection 74a and the front end surface of the first cam B projection 75a. The frictional force is generated by the surface contact between the front end surface of the second cam A projection 74b and the front end surface of the second cam B projection 75b, so that the second frame 12 stops at that position. Stays in the state. Thereby, since the display of the 2nd frame 12 and the keyboard provided in the upper surface of the 1st frame 11 are exposed, keyboard operation becomes possible while watching a display. When the angle of the display (second frame body 12) is to be adjusted within the range of 45 degrees to 180 degrees, the second frame body 12 is rotated with respect to the first frame body 11 to a desired position. When stopped, the display remains stationary at that position, so that the angle of the display can be easily adjusted to the desired angle.

After use, in order to return to a closed state, the 2nd frame 12 is rotated with respect to the 1st frame 11 in the closing direction. At this time, the front end surface of the first cam A protrusion 74a and the front end surface of the first cam B protrusion 75a make sliding contact while being in surface contact with each other, and at the same time, the second cam A protrusion 74b and the second cam are moved. When the B protrusions 75b are in surface contact with each other and slide, and the rotation angle is 45 degrees, the first cam A protrusion 74a and the first cam B protrusion 75a and the second cam A protrusion 74b are engaged. And the coupling of the second cam B protrusion 75b are released, respectively. From 45 degree to 15 degree rotation angle, the 2nd frame 12 is rotated by resisting the acting force of the compression spring 56. FIG. When the rotational angle is smaller than 15 degrees, the contact portion 55 of the slider member 52 reaches the one inclined surface after sliding the tip portion on the other inclined surface of the cam projection 54, so that the compression spring 56 The second frame 12 is automatically rotated with respect to the first frame 11 until the rotational angle is 0 degrees, that is, the closed state, and the first frame 11 and the second frame 12 Are kept closed, overlapping each other.

Therefore, the hinge device 1 and the portable device 10 according to the present invention have a region in which the first frame body 11 automatically rotates during the opening and closing operation, and at the same time releases the fixed state at the time of opening. Since the fixed state releasing operation is unnecessary, the opening and closing operation with good operability can be performed.

In addition, the suction mechanism 5 and the pop-up mechanism 6, in particular the pop-up mechanism 6, a slider member 52 reciprocating in a linear direction, and a force action member for applying a force to the slider member ( By providing the compression spring 56 of 53), since the pressing direction of the slider member 52 is in a linear direction, even if the second frame 12, which is relatively heavy, such as a notebook, the second frame 12 is sufficient. The popup mechanism 6 can automatically rotate. Moreover, the suction mechanism 5 and the pop-up are used by using the cam body 51, the slider member 52, the compression spring 56, the cam A body 71, the cam shock body 72, the leaf spring 78, and the like. Since the mechanism 6 and the friction mechanism 7 are constituted, the structure becomes simple, the number of parts is reduced, and the price can be reduced and the size can be reduced.

As described above, the hinge device and the portable device according to the present invention have an area in which the support member automatically rotates by the pop-up mechanism when the first frame body and the second frame body are opened. When the frame is closed, the support member has an area which is automatically rotated by the suction mechanism and the first and second frame bodies are kept closed by the suction mechanism, so that the operability of opening and closing with good operability can be performed. It is especially suitable for use in notebooks.

According to the configuration and operation of the hinge device and the portable device according to the embodiment of the present invention described above, there is an effect such as open and close operation with good operability.
