[0021]
As shown in FIGS. 11B and 12, the push-type hinge 30 generates a closing torque by the fully closed lock step 30A when the opening angle is about 20 degrees or less, and opens the opening torque by the release step 30B when the opening angle is larger. To generate a click at about 130 degrees, a closing torque is generated by the stop step 30D between 130 degrees and 145 degrees, and an open torque is generated by the regulation step 30C between 145 degrees and 160 degrees (fully open state OHA). Let it.
[0022]
Next, the operation when the push button key 60 is pressed will be described.
When the push button key 60 is pushed in against the second compression spring 50, the cam holder 46 and the cam 42 are moved through the two cam locking claws 62, 62 of the push button key 60 and the push button key attaching portion 45 of the cam 42. The locked state is released, and the cam 42 can freely rotate with respect to the push button key 60 and the cam holder 46. Therefore, in the fully closed state OHC, when the push button key 60 is pressed from a state in which the closing torque is normally generated, the rotation of the cam 42 becomes free, so that the generation of torque is eliminated.
[0023]
Since the notches 45b, 45b for locking the push button key of the cam 42 and the claw portions 62, 62 for locking the cam of the push button key 60 are arranged at 180 degrees, the push button key 60 is pushed in the fully closed state OHC and rotated. When this is done, the state where the push button key 60 is pushed down is maintained up to 180 degrees, and the free rotation of the cam 42 is prevented, and when rotated 180 degrees, the locking portions match and the state where the push button key 60 is pushed down returns. Then, the state returns to the state where the cam holder 46 and the cam 42 are locked via the push button key 60. Also, since the pawls 62a, 62a of the cam locking pawls 62, 62 of the push button key 60 are chamfered, the second compression in the fully open state OHA (160 °) without rotating to 180 °. Due to the load of the spring 50, the push button key 60 returns while rotating the cam to a position of 180 degrees according to the chamfered portion.
[0024]
Next, the mobile phone 1 according to the present embodiment will be described.
First, when the push button key 60 is not depressed, the normal torque of the push-type hinge 30 and the torque of the open hinge 10 are combined as shown in FIG. A closing torque, an opening torque between 20 ° and 130 °, a closing torque between 130 ° and 145 °, and an opening torque (locking force at full opening) between 145 ° and 160 ° are generated.
[0025]
When the push button key 60 is not depressed and the opening angle is 20 degrees or less, as shown in FIG. 13, in the open hinge 10, the sliding pin 25 is at the initial position of the cam surfaces 21 and 21, and the push hinge In FIG. 30, the opposing cam 40 is located on the ascending inclined surfaces 43a, 43a of the cam surfaces 43, 43, and the push button key mounting portion 45 of the cam 42 in the push-type hinge 30 has two protrusions 45a, 45a, The two cam locking claws 62, 62 are locked.
[0026]
Next, when the push button key 60 is depressed, the torque of the push-type hinge 30 is lost as shown in FIG. 12 as normal, so that the display-side housing 3 is fully opened only according to the torque of the open-type hinge 10 (opening torque). It rotates by the torque generated by the open hinge 10 up to OHA.
FIG. 14 shows a state immediately after the push button key 60 is pressed. At this point, the two cam locking claws 62 of the push button key 60 are disengaged from the two projections 45a, 45a of the push button key mounting portion 45 of the cam 42 in the push hinge 30, but in the open hinge 10, The sliding pin 25 is located at the initial position of the cam surfaces 21 and 21, and in the push-type hinge 30, the opposing cam 40 is located on the ascending inclined surfaces 43a and 43a of the cam surfaces 43 and 43.
[0027]
Next, as shown in FIG. 15, the opposing cam 39 is in a state where it can rotate with respect to the cam 42.
Next, the light passes through the opening angle of the display-side housing 3 shown in FIG. 16 of 90 degrees and the opening angle of the display-side housing 3 shown in FIG. 17 at 140 degrees, and the display-side housing 3 shown in FIG. 160 degrees).
[0028]
Next, when the display-side housing 3 is rotated to the fully open state OHA (160 degrees), the push button key mounting portion 45 of the cam 42 in the push hinge 30 has two protrusions 45a, 45a as shown in FIG. The two cam locking pawls 62, 62 are locked.
As a result, the push button key 60 is restored, the cam 42 of the push hinge 30 is locked, and torque is generated according to the cam 42.
[0029]
At the same time, the parallel pins 25 of the open hinge 10 fit into the recesses 23, 23 to form a fully open lock step 10B.
Next, when the operator pushes the display side housing 3 in the closing direction, a click occurs at the first predetermined position OHB (130 degrees) as shown in FIG. The click on the display-side housing 3 can be stopped at (degree).
[0030]
As described above, according to the mobile phone 1 according to the present embodiment, when not in use, the push-type hinge 30 restricts the movement of the open-type hinge 10 and the display-side housing 3 is held in the fully closed state OHC. When the push button key 60 of the hinge 30 is pressed, the regulation by the push hinge 30 is released, and the display side housing 3 is opened by the open hinge 10 to the fully open state OHA by the restoring force of the compression spring 19.
[0031]
Then, when the display-side housing 3 starts to be closed in the fully-closed-state OHC direction from the fully-open state OHA, the display-side housing 3 is click-stopped at the first predetermined position OHB (130 degrees), and the first predetermined position OHB ( 130 degrees). Therefore, at the first predetermined position OHB (130 degrees), the mobile phone 1 can be operated by placing it on a table or the like, for example, like a notebook computer.
[0032]
When the display side housing 3 is closed from the first predetermined position OHB (130 degrees) in the fully closed state OHC direction, a closing torque by the push-type hinge 30 acts at an opening angle of 20 degrees or less to display. The side housing 30 can be overlaid on the operation side housing 5 to form a fully closed state OHC.
[0033]
【The invention's effect】
In the present invention, the function of the push-type hinge is assigned to the left and right hinges, so that the space of the dummy hinge can be effectively used, and the overall length of the hinge can be reduced.
In the present invention, since the cam portion of the push hinge is provided with a shape for generating the click torque, it is possible to set the click generation only in the closing stroke when the push hinge is fully opened to the full open state and then returned from the full open state.
[0034]
In the present invention, by using a parallel pin as a mating member of the cam of the open hinge, the hardness and surface roughness of the mating component can be improved, and the operation can be smooth and the friction can be reduced. Become.
In the past, components (such as E-rings) were provided separately from the mating member of the cam. However, since parallel pins can be used as built-in positioning components, these components become unnecessary, reducing the number of components and the number of assembly steps. As a result, cost can be reduced.
