Description

Curling Hinge Device {CURLING HINGE DEVICE}

The present invention relates to a curling hinge device, and more particularly, to a curling hinge device which is applied to opening and closing of a relatively heavy item such as a notebook, a liquid crystal monitor, etc., and whose configuration is simple and facilitates position fixing during opening and closing. .

In general, the hinge device installed in the notebook, the liquid crystal monitor is configured to support the rotation operation in a relatively simple configuration, the notebook is installed to support the opening and closing operation of the top plate, the liquid crystal monitor to adjust the rotation angle of the monitor Is installed.

While the hinge device is manufactured in a simple configuration, it is possible to easily adjust the rotation angle of the top plate of the notebook or the liquid crystal monitor, and the configuration is such that the angle is not easily changed in the adjusted state.

As an example of the hinge device as described above, the curling hinge shown in FIG. 4 is used a lot, which is a rotation shaft 51 coupled to a liquid crystal monitor and the like, and the rotation shaft 51 is inserted into the friction force while being pressed at a predetermined pressure. It consists of a hinge bracket 52 of the curling (CURLING) form to generate.

That is, the rotation shaft 51 is pressed by a predetermined pressure by the hinge bracket 52, the rotation shaft 51 is stopped at a certain angle, thereby keeping the monitor inclined at a certain angle.

However, when the curling hinge bracket is used to maintain the rotation angle of the liquid crystal monitor at a predetermined angle as described above, it is difficult to control the position of the monitor due to the limitation of the frictional force, so that the monitor does not stop at a desired position.

In order to solve the above problems, a plurality of hinge brackets were installed according to the size of the monitor to increase the friction force, but there was also a problem that the assembly was not easy and the configuration became complicated due to the limited space.

Accordingly, an object of the present invention is to solve the above problems, and simplifies the configuration of the curling hinge device used in devices such as liquid crystal monitors and laptops, and increases the pressure to precisely adjust the rotation angle at the position desired by the user. The present invention provides a curling hinge device capable of improving the durability and fixing force of the hinge device.

As described above, the present invention is configured such that the pressing force applied to the rotating shaft is increased, the rotation angle is precisely adjusted at the desired position of the rotating shaft, the durability and fixing force of the hinge device are improved, and the structure is simple, and the assembly is easy. have.

1, 2 and 3 is an exploded perspective view, an assembled perspective view and an assembled cross-sectional view showing a curling hinge device according to the present invention, a hinge bracket (2) fixed to the main body of a notebook or a stand of a liquid crystal monitor, and the hinge It is inserted into the bracket (2) is pressed to a certain pressure while rotating by rotating the rotation shaft (1) at a certain angle, and is coupled to the outer surface of the hinge bracket (2) to press the hinge bracket (2) It consists of the clip 3 which is a metal material.

That is, the clip 3 presses the hinge bracket 2, and as a result, the pressing force for the hinge bracket 2 to press the rotary shaft 1 is increased, thereby fixing the rotary shaft 1 with greater frictional force. You will be able to.

Of course, the friction force is set so that the user can be opened and closed with a relatively small force when the user grasps the top plate or the liquid crystal monitor of the notebook and rotates, and the rotation position is easily fixed in proportion to the weight of the rotated part.

Here, when the clip 3, which is a metal material, is coupled to the hinge bracket 2, a large friction force can be obtained without forming the hinge bracket 2 thickly, and the hinge bracket 2 and the clip 3 of the clip 3 can be obtained. By setting the pressing force in two steps, the pressing force can be set more precisely.

That is, when the pressing force is set by forming the hinge bracket 2 thickly, not only the setting of the pressing force according to the thickness is difficult, but also because the thickness is thick, the pressing force does not increase proportionally. It is easier to adjust the pressing force (friction force) with).

Referring to the operation and effect of the present invention as described above, one side of the rotating shaft 1 is inserted into the hinge bracket 2 so that the rotating shaft 1 is pressed by the hinge bracket 2 at a predetermined pressure, and the rotating shaft 1 ) Is coupled to the metal clip (3) so that the pressing force is increased to the outer surface of the hinge bracket (2) is inserted.

The hinge bracket 2 coupled as described above is fixed to a main body of a notebook or a stand of a liquid crystal monitor, and the other side of the rotating shaft 1 is screwed to a top plate of a notebook or a monitor.

In this case, when an external force is applied to the top plate or the monitor of the notebook, the rotating shaft 1 screwed to the top plate or the monitor of the notebook is rotated, and when the external force is removed, the rotation shaft 1 is fixed by the frictional force. The state will be maintained.

Here, the pressing force applied to the rotating shaft 1 according to the weight of the top plate or the monitor of the notebook is increased so that the clip 3 is coupled to the outer surface of the hinge bracket 2 so that the fixed state of the rotating shaft 1 is maintained. Even if the hinge bracket 2 is not formed thick, a large pressing force can be obtained.

In addition, as the pressing force is increased, the rotation angle of the top plate or the monitor of the notebook is precisely adjusted at a desired position, and the durability and fixing force of the curling hinge device are improved.
