Cylinder Clip Type Friction Hinges {FRICTION HINGE DEVICE WITH A CYLINDRIC CLIP}

The present invention relates to a cylinder clip-type friction hinge device, and more particularly to a cylinder clip-type friction hinge device in which the hinge shaft rotates only when a torque of a predetermined size or more is applied due to the friction force between the cylinder clip into which the hinge shaft is inserted and the hinge shaft. It is about.

Referring to FIG. 1, a conventional cylinder clip type friction hinge device includes a cylinder clip 10 and a hinge shaft 20 rotatably inserted into the cylinder clip 10.

The cylinder clip 10 has a cutout portion 11 having a constant width in the longitudinal direction and extends flatly from one end portion of the cutout portion 11 to a specific length with respect to the other end portion of the cutout portion 11. An extension 12 is formed to keep the width of the cutout 11 constant.

The hinge shaft 20 is rotatably inserted into the cylinder clip 10 and has a spiral oil groove 21 closed at both ends on an outer surface having an outer diameter larger than the inner diameter of the cylinder clip 10.

The conventional cylindrical clip-type friction hinge device configured as described above is a cutout of the cylinder clip 10 when the hinge shaft 20 having an outer diameter larger than the inner diameter of the cylinder clip 10 is inserted into the cylinder clip 20. Since 11 is opened, the width of the cutout 11 is larger than before the hinge shaft 20 is inserted into the cylinder clip 10.

In this case, the cylinder clip 10 exerts an elastic force on the outer surface of the hinge shaft 20, as a result of the friction between the inner surface of the cylinder clip 10 and the outer surface of the hinge shaft 20, a predetermined size The hinge shaft 20 rotates inside the cylinder clip 10 only when the above torque, for example, a torque exceeding the frictional force is applied.

Meanwhile, the conventional cylindrical clip-type friction hinge device is divided into a main body and a stand, and is used as a hinge device for connecting the main body and the stand to each other in a device in which the stand rotates based on the main body. It is used for LCD monitors for desktop computers.

When a conventional cylinder clip type friction hinge device is utilized in the notebook computer, the main body and the monitor panel of the notebook computer correspond to the main body and the stand, respectively.

FIG. 2 is an exploded perspective view showing a cylinder clip friction hinge device improved to a structure for utilizing a cylinder clip friction hinge device as shown in FIG. 1 in a notebook computer, and the improved cylinder clip friction hinge device is 2 per notebook computer. Hinge devices are mounted on both sides of the monitor panel.

Referring to FIG. 2, the cylinder clip 10a has a cutout portion 11a having a predetermined width in the longitudinal direction, and extends flatly at a specific length from one end of the cutout portion 11a to the cutout portion 11a. An extension portion 12a to which a main body (for example, a main body of a notebook computer) is mounted is formed while keeping the width of the cutout portion 11a constant with respect to the other end of the ().

The hinge shaft 20a is provided with a fixing part 22 to which a stand (for example, a monitor panel) is mounted on one side, and is rotatably inserted into the cylinder clip 10a on the other side of the hinge shaft 20a. The friction part 23 in which the spiral oil groove 21a with the both ends closed is formed in the outer surface which has an outer diameter larger than an inner diameter is formed.

Between the fixing portion 22 and the friction portion 23 of the hinge shaft 20a connects the fixing portion 22 and the friction portion 23 and the cylinder clip 10a into which the friction portion 23 is inserted. The connection catching part 24 which catches one end part is formed.

In the case where the cylindrical clip-type friction hinge device is utilized in the notebook computer as described above, the notebook panel user must apply torque exceeding the friction force generated between the cylinder clip 10a and the hinge shaft 20a so that the monitor panel cannot be used. It rotates based on the main body of a notebook computer.

When the conventional cylinder clip type friction hinge device is utilized in the LCD monitor for the desktop computer, the hinge bracket and the LCD monitor panel serving as a pedestal correspond to the main body and the stand, respectively.

FIG. 3 is an exploded perspective view showing a cylinder clip friction hinge device improved to a structure for utilizing a cylinder clip friction hinge device as shown in FIG. 1 in an LCD monitor, and the improved cylinder clip friction hinge device is used per LCD monitor. Two hinge devices are mounted on both sides of the LCD monitor panel.

Referring to FIG. 3, the cylinder clip 10b has a cutout portion 11b having a constant width in a longitudinal direction, and extends flatly at a specific length from one end of the cutout portion 11b to the cutout portion 11b. An extension portion 12b is formed in which the width of the cutout portion 11b is kept constant with respect to the other end of the circumference, and the flattened end is bent.

The hinge shaft 20b is rotatably inserted into the cylinder clip 10b, and a stand (for example, an LCD monitor panel) is mounted on one side thereof, and a plurality of hinge shafts 20b are provided on the outer surface having an outer diameter larger than the inner diameter of the cylinder clip 10b. The oil groove 21b is formed.

The hinge bracket 30 has a clip hole 31 into which the cylinder clip 10b is inserted and fixed, and supports a stand (eg, an LCD monitor panel) mounted at one side of the hinge shaft 20b. Play a role.

In the case where the cylindrical clip-type friction hinge device is utilized for the LCD monitor as described above, the user of the desktop computer must apply a torque exceeding the friction force generated between the cylinder clip 10b and the hinge shaft 20b. It rotates based on this hinge bracket 30. As shown in FIG.

However, the conventional cylindrical clip-type friction hinge device utilized in LCD monitors for notebook computers or desktop computers as described above, as long as a torque exceeding the friction force generated between the cylinder clip and the hinge shaft is applied regardless of the user's intention. The hinge axis has the disadvantage of rotating inside the cylinder clip.

For example, in the case of an LCD monitor for a desktop computer, although the user does not intend to rotate the LCD monitor panel, the user or another user accidentally exceeds the friction force generated between the cylinder clip and the hinge axis on the LCD monitor panel. When the torque is applied, the LCD monitor panel is arbitrarily rotated to easily move away from the position set by the user.

In the case of the notebook computer as shown in Fig. 4, in the initial state where the monitor panel 104 is folded on the main body 102, if the user grasps both sides of the monitor panel 104, the main body (by the weight of the main body) 102 is rotated arbitrarily and opens downward. On the contrary, when the user grasps both sides of the main body 102 and flips the main body 102, the monitor panel 104 is arbitrarily rotated and opened downward by its own weight. .

Accordingly, in order to prevent the monitor panel 104 from rotating arbitrarily from the main body 102 regardless of the user's intention in the initial state in which the monitor panel 104 is folded in the main body 102 of the notebook computer. A locking device composed of a latch groove 106 formed in the monitor panel 104 to allow locking and unlocking operations by the locking groove 106 formed in the 102 and the button 124 is further added to a conventional notebook computer. There is a downside to installing it.

The present invention is to overcome the above-mentioned conventional problems, an object of the present invention is a rotation preventing plane portion formed along the longitudinal direction on the outer surface of the hinge shaft of the circular cross section along the longitudinal direction on the inner surface of the cylinder clip into which the hinge shaft is inserted It is to provide a cylindrical clip-type friction hinge device that is in close contact with the formed anti-rotation plane to prevent the rotation axis to rotate arbitrarily regardless of the user's intention.
