TECHNICAL FIELD The present invention relates to a hinge device, and more particularly, to a door hinge device for rotatably connecting a door as a flow member to a fixed part such as a wall surface so as to open and close a door, and, inter alia, to a glass door. A hinge device more suitable for the following.

Various types and types of hinge devices that have been applied to various fields have been developed. That is, hinge devices of various sizes and shapes are being used, ranging from folding parts of portable small devices such as notebooks and mobile phones according to the trend of miniaturization and light weight of products, to large devices such as containers and medium and long-term devices. In addition, hinge devices with new functions, which have not been conventionally developed, are being developed one after another according to the multifunctionality and high-end of various equipment including electronic related products.

Among these hinge devices, the hinge device applied to the connection of the swing door has a long history, while the glass glass itself is directly mounted on the glass by adopting the glass glass itself as the door rotating plate not only for the functional aspect of the door but also for aesthetic appearance. The hinge devices of the structure are relatively recently and are being developed in earnest.

For example, in the case of a glass structure such as a shower booth in which several sheets of glass plates are connected to each other, a hinge device for a glass door that is rotatably connected to a wall or a fixed adjacent glass sheet which is also made of glass. Although glass plate structures such as glass booths for showers, which have many functions and aesthetics, have been constructed by applying them, the components such as hinge devices are mounted directly on the glass itself without a separate frame. In this case, due to the material characteristics of the glass sheet material difficult to process and molding the finished product, there is a limit such as the application of additional parts, such as to supplement the door opening function or to add other useful functions is relatively difficult.

Therefore, in order to maintain the closed state of the glass door in a stable state or to give a function of stably maintaining the open state at a certain angle (for example, an open angle of 90 ° from the closed state), it is necessary for Instead of mounting a separate device, it is desirable to add a configuration to perform the function on the hinge device itself.

In one example of such a configuration, a fixing groove is formed on an outer surface of a bush (a cylindrical portion surrounding a shaft hole for accommodating a hinge axis) of one gripping portion among the two rotatable portions rotatably connected to constitute a hinge device, and By applying pressure to the outer surface of the bush by elastic means such as a spring, and having a follower having a contact surface in a form that can be seated in the fixing groove, the cam is applied to the fixing groove during rotation by applying a cam function. A hinge device configured to maintain a stable fixed state at a rotation angle at which the contact surface of the follower is seated has been provided.

That is, by the above configuration, the rotation of the glass door is fixed at a certain angle where the fixing groove and the driven body are engaged without the addition or installation of additional equipment, so that the door is opened by itself or a half-open state unless a certain force is applied. The doors could be prevented from being placed at unwanted angles.

Furthermore, the hinge configured to stably fix the rotation angle of the door in two or more angle sections (for example, in a closed state and 90 ° open therefrom) by further extending the above-described configuration to form two or more fixing grooves. Devices have also been provided.

Nevertheless, in the case of the above-described conventional hinge device in which the fixing groove is fixedly fixed to one gripping portion (the bush outer surface of the bushing), a stable closing or opening state is maintained only at the originally designed angle, so that various types of places and If it is necessary to change the rotational fixing angle to meet the changing needs of the situation, there is no choice but to replace it with another hinge device having a different rotational fixing angle. There was a disadvantage due to the increase, and if there is no hinge device provided that can fix the rotation of the door at a desired rotation angle, the installation of the door according to the initial plan or design may not be possible.

The hinge shaft is inserted into the hinge device, which is not observed in FIG. 1 showing the appearance of the hinge device, and the characteristic configuration of the hinge shaft according to the present invention is better described with reference to FIGS. It will be described later in detail.

At this time, a big difference from the conventional hinge device found in appearance through FIG. 1 is that, in the case of the conventional hinge device, only the bushes 12 and 22 of the respective gripping parts 10 and 20 surrounding the hinge axis are used for the hinge device. In the hinge device according to the present invention, the hinge device according to the present invention, in addition to the bushes 12 and 22, is a component called the rotating cam part 30 according to the configuration of the present invention.

The rotating cam unit 30 is an essential part for freely setting and changing the rotation fixing angle, and a more detailed configuration and function thereof will be described in detail with reference to the accompanying drawings.

Figure 2 is an exploded perspective view of the hinge device according to a preferred embodiment of the present invention, showing all the components included together.

The first gripping portion 10 and the second gripping portion 20 are mutually positioned such that the axial holes 15 and 25 formed in the bushes 11 and 21 are arranged in a straight line, and then the axial holes arranged in a straight line ( The hinge shafts 50 are inserted into and penetrated to the 15 and 25 so as to be rotatable with each other.

At this time, as shown, according to a preferred embodiment of the present invention, between the first gripping portion bush 12 and the second gripping portion 22, the shaft hole that can be inserted into the hinge shaft 50 ( A rotating cam unit 30 having a 35) is interposed.

In addition, a follower 40 which is in contact with the outer surface of the rotation cam portion 30 to apply a pressure in the direction of the rotation center is further included, which is the driven body receiving groove of the first gripping portion 10 as shown 13 may be configured in a form in which the follower 40 is seated together with the elastic means 45 such as a spring.

On the other hand, the hinge shaft 50 according to a preferred embodiment of the present invention shown through Figure 2 has a different form from the conventional hinge axis, in the case of the hinge axis 50 shown is two different in cross-sectional diameter of the cylinder The section is formed, it can be seen that the stepped fixing jaw portion 51 is formed in the boundary portion.

The diameter of the two sections divided by the fixed jaw portion 51 as a boundary is smaller than the diameter of the shaft hole 35 of the rotation cam portion 30 when the diameter is smaller, and the rotation cam portion when the diameter is larger ( By forming larger than the diameter of the shaft hole 35 of the 30, the hinge shaft 50 of the first gripping portion 10, the second gripping portion 20 and the rotation cam portion 30 to the shaft holes 15, 25, 35 When the fixed jaw portion 51 is inserted into the rotating cam portion 30 is configured.

This configuration will be described in more detail with reference to FIG. 3, which shows only the second gripping portion 20, the rotation cam portion 30, and the hinge shaft 50. In this case, the first gripping portion 20 is actually always connected together via the hinge axis 50, but the first gripping portion 20 is omitted in order to express a more clear structure.

As shown, the hinge shaft 50 has a stepped fixing jaw 51 and a male thread 52 on the outer surface of the tip portion inserted into the shaft holes 15, 25, 35.
