[0006]
[Problems to be solved by the invention]
However, the hinge 200 described in JP-T-2000-501149 has a large number of components and is complicated, so that it has been difficult to reduce the weight and size.
[0007]
Accordingly, an object of the present invention is to provide a hinge that can reduce the number of parts, reduce the weight and size, and generate an appropriate friction torque.
[0008]
[Means for Solving the Problems]
In order to solve the above problems, the present invention provides a first member having a cylindrical shaft member and a first support portion formed continuously with the shaft member in a longitudinal direction of the shaft member. A shaft case having a cylindrical spilling pin with a slit in the longitudinal direction and a cylindrical internal space in which the spilling pin can be housed in a state where the shaft member is inserted into the spilling pin. A second member having a second support portion formed continuously with the shaft case in a longitudinal direction of the shaft case, and attaching the first support portion to a first body. A hinge configured to attach the second support portion to a second main body so that the first main body and the second main body can be rotatably connected to each other; Between the outer peripheral surface of the shaft case and the inner peripheral surface of the shaft case. By inserting the shaft member and the spilling pin into the internal space so as to sandwich the spilling pin, between the inner peripheral surface of the shaft case and the outer peripheral surface of the spilling pin, or the shaft member The first member and the second member are kept stationary at an arbitrary angle by generating a frictional force between the outer peripheral surface of the first member and the inner peripheral surface of the spilling pin. Provide a hinge that can be used.
[0009]
The first member has a cylindrical shaft member protruding in one direction, and a first support portion formed continuously with the shaft member in a longitudinal direction of the shaft member.
[0010]
The shaft member is formed in a cylindrical shape large enough to come into contact with the inner peripheral surface of the spilling pin so that a frictional force is generated between the shaft member and the inner peripheral surface of the spilling pin when rotating. .
[0011]
The spilling pin has a slit in the longitudinal direction.
[0012]
This is to provide elasticity by inserting slits.
[0013]
The spilling pin is sandwiched between an outer peripheral surface of a shaft member and an inner peripheral surface of a shaft case described later, and is formed in a cylindrical shape having a size and thickness so as to be in contact with both surfaces.
[0014]
The second member includes a shaft case, and a second support portion formed continuously with the shaft case in a longitudinal direction of the shaft case.
[0015]
In the shaft case, a cylindrical internal space is formed so that the shaft member can be housed inside the spilling pin with the shaft member inserted into the spilling pin.
[0016]
That is, in a state where a cylindrical shaft member is covered with a cylindrical spilling pin, a cylindrical internal space that can be housed inside the shaft case is formed, and the outer peripheral surface of the spilling pin and the shaft case are formed. So that it comes into contact with the inner peripheral surface.
[0017]
Then, the first member, the spilling pin and the second member attach the first support of the first member to the first body, and connect the second support of the second member to the second body. By attaching to the main body, the first main body and the second main body can be rotatably connected.
[0018]
At this time, the shaft member and the spilling pin are inserted into the inner space of the shaft case so that the spilling pin is sandwiched between the outer peripheral surface of the shaft member and the inner peripheral surface of the shaft case, so that the inner circumference of the shaft case is A frictional force is generated between the surface and the outer peripheral surface of the spilling pin, or between the outer peripheral surface of the shaft member and the inner peripheral surface of the spilling pin.
[0019]
In this way, the first member and the second member can be kept stationary at an arbitrary angle by generating the frictional force.
[0020]
Here, at least one of the inner peripheral surface of the shaft case, the outer peripheral surface of the spilling pin, the outer peripheral surface of the spilling pin or the outer peripheral surface of the shaft member has a groove for storing a lubricant. By forming the first member and the second member, the first member and the second member can be smoothly rotated.
[0021]
The shape of the groove can be appropriately selected within a range in which the lubricant can be stored, such as an arc-shaped or trapezoidal cross section.
[0022]
Further, the display main body and the keyboard main body of the laptop personal computer can be connected by the above-mentioned hinge, and the present invention can also be used for a portable DVD player, a foldable mobile phone, and the like.
[0023]

[0026]
As shown in FIG. 2, the shaft member 104 has a columnar shape with a circular vertical cross section, and the diameter A is substantially the same as the inner diameter B of the cylindrical spring pin 102. By forming the shaft member 104 when the shaft member 104 is inserted into the spring pin 102, the outer peripheral surface of the shaft member 104 comes into contact with the inner peripheral surface of the spring pin 102, and when the shaft member 104 is rotated, A frictional force is generated between these surfaces.
[0027]
Further, as shown in FIG. 2, the first support portion 105 constituting the first member 101 is formed in a flat plate shape, and the first member 101 is, for example, a laptop type. A screw hole 106 is provided for attachment to a display body or the like of a personal computer with a screw.

[0030]
Further, the spring pin 102 is made of spring steel and further has a wavy slit 109 in the length direction, so that the spring pin 102 is moved in a direction perpendicular to its central axis. It will have elasticity.
[0031]
Further, the length D of the spring pin 102 is the same as the length C of the shaft member 104 of the first member 101, so that the entire shaft member 104 can be accommodated therein. .
[0032]
The second member 103 includes a shaft case 110 and a second support 111.
[0033]
As shown in FIG. 4, the shaft case 110 has a cylindrical internal space 112 that can accommodate the spring pin 102.
[0034]
That is, the diameter E of the internal space 112 formed in a cylindrical shape is substantially the same as the outer diameter F of the spring pin 102, and the length G of the internal space 112 is also equal to the length D of the spring pin 102. And are almost identical.
[0035]
As for the shaft case 110, like the shaft case 210 shown in FIG. 5, a groove 213 having an arc-shaped cross section can be formed in the inner peripheral surface 210a in a spiral shape.
[0036]
By providing such a groove 213, a lubricant such as grease can be stored inside the groove 213, and the movement of the shaft case 210 and the spring pin 102 can be performed smoothly.
[0037]
Here, the groove 213 is formed in the inner peripheral surface 210a of the shaft case 210, but the present invention is not limited to this, and the outer peripheral surface 104a of the shaft 104, the inner peripheral surface 102a or the outer peripheral surface of the spilling pin 102 is formed. It is also possible to provide a groove in 102b.
[0038]
As shown in FIG. 4, the second support portion 111 constituting the second member 103 is formed in a flat plate shape. For example, the second support portion 111 is screwed to a keyboard body or the like of a laptop personal computer. A screw hole 106 for attachment is formed.
[0039]
As described above, since the first member 101, the spring pin 102, and the second member 103 are configured, the spring pin 102 is put on the shaft member 104 of the first member 101, and the shaft case of the second member 103 is formed. The first member 101 and the second member 103 can be rotated in the XX ′ and YY ′ directions as shown in FIG. Will be able to
[0040]
The diameter A of the shaft member 104 and the inner diameter B of the spring pin 102 are substantially the same, and the outer diameter F of the spring pin 102 and the diameter E of the inner space 112 of the shaft case 110 are substantially the same. Therefore, when the first member 101 and the second member 103 are rotated, between the inner peripheral surface of the shaft case 110 and the outer peripheral surface of the spilling pin 102, or A frictional force is generated between the outer peripheral surface of the shaft member 104 and the inner peripheral surface of the spilling pin 102.
[0041]
By making such a frictional force occur, for example, when this hinge 100 is used in a laptop personal computer and the keyboard main body and the display main body are connected, the keyboard main body and the display main body are rotated. In addition to being movable, the keyboard main body and the display main body can be held at a predetermined angle.
[0042]
The magnitude of the frictional force is determined by the material forming the first member 101, the spring pin 102, and the second member 103, the area and roughness of the surface that comes into contact with them, and the vertical effect on these contact surfaces. Although it varies depending on the size and the like, how much frictional force is generated can be selected as appropriate depending on what kind or purpose this hinge is used for.
[0043]
【The invention's effect】
Since the present invention is configured as described above, it is possible to provide a hinge that can reduce the number of parts, reduce the weight and size, and generate an appropriate friction torque.
