Description

The apparatus for being installed with the safety hinge for door and preventing that the hand is put between}

The present invention relates to a device for preventing hand pinching, which is installed by a safety hinge for a door, and more particularly, to install a safety cover for preventing hand pinching, while improving the construction property of a safety door.

In general, the basic structure of a swing door mainly used in buildings or houses is a structure in which the door hinge is mounted on the door frame to open and close while rotating by the hinge, and a gap between the door frame and the door inevitably occurs due to the hinge structure. On the contrary, when the door is closed, the gap between the door frame and the door is eliminated. Therefore, there is a problem that a safety accident occurs when a part of the user's body is caught in the gap when the door is closed.

In particular, the installation of safety doors has become a legal recommendation in recent years, and local governments that have the right to complete the construction have required the installation of safety doors. Therefore, the installation of safety doors without gaps between door frames and doors has been continued. Is required.

Therefore, recently, as disclosed in Korean Patent No. 1630135 (2016.06.07.), A safety door equipped with a safety cover of a curved surface has been disclosed so that a door gap does not occur.

That is, by providing a separate safety cover so that no gap occurs when the door is opened or closed, a safety accident can be prevented by preventing any part of the body such as a finger from being caught even when the door is opened.

However, such a conventional safety door has a problem that the mounting structure and the operation structure of the safety cover to prevent the occurrence of a gap when the door is opened, the structure is very complicated, and in some cases the door and the door to install the safety cover It requires that the design of the door frame be changed.

In other words, when the door is closed, the safety cover is not exposed and the safety cover is exposed only when the door is opened so that a gap does not occur between the door frame and the door, and the mounting structure of the safety cover should not be exposed to the outside. Therefore, there is a problem that the installation structure is very complicated.

In particular, as a structure for mounting the hinge so that the assembly is not exposed to the outside without a protruding part in appearance, as shown in Figure 1 and 2 in recent years to install the mounting bar 10 in the door (D) and its After connecting the installation bar and the door frame with the hinge 20, the hinge shaft 30 is vertically assembled and the safety cover 40 is hinged together with the hinge, but this installation method has been proposed after extrusion molding the installation bar Since the internal space 12 for mounting the hinge has to be dug out by working, the productivity of the subsidiary materials is very low.

In addition, since the installation bar 10 itself is a structure that receives a load when the door is opened and closed, there is a problem that the cost of the safety door must be manufactured because it must be made of a metal frame to secure rigidity, and in order to post-process metal materials There is a problem that the productivity is very low because the work process is more difficult.

In addition, since the hinge shaft 30 is vertically and vertically inserted, the construction is not only difficult in the field but also causes unnecessary waste of materials.

And it is very difficult to manufacture the subsidiary materials and parts according to the complex assembly structure as described above, there is a problem that the installation cost increases because the manufacturing cost of the subsidiary materials and parts is increased.

The present invention is to solve the above problems, to simplify the installation structure of the safety hinge and to be made of a structure that can be assembled without post-processing the subsidiary materials to improve the productivity of the subsidiary materials and accessories and to construct a safety door at a low cost I would have to.
