Description

Hand-holding safety hinges for narrow door frames

The present invention relates to a safety device that prevents injuries caused by pinching a finger through a door frame that is opened and closed by a hinge and a door gap between the door leaf, and more specifically, it can be installed on an existing wide door frame. Of course, it is possible to install all of the narrow door frames to secure the door width that opens and closes.

In addition, by simplifying parts than before, the installation and handling are further improved, while providing excellent aesthetics so that the installed parts are not visible from the outside.

In general, most of the door structure consists of an opening and closing method in which a door frame and a door are opened and closed in one direction by a hinge at the entrance and the entrance opened for access to a space partitioned indoors.

At this time, the hinge is made of a certain thickness and the hinge part is positioned so that the hinge part protrudes from one side of the door, so that the fixing blades of the hinge are fixed to the door frame and the door with screws, and are mounted to be exposed. The stepped surface is provided so that there is no gap between the doors, so that even when the fixing blades of the hinge are screwed, they are not exposed to the outside.

However, when the door is opened, a significant separation space is provided between the door frame and the hinge of the door, and if fingers, etc. are caught in this separation space, there is a concern of considerable injury due to the pinching of the finger. .

Therefore, in order to cover the door gap between the door frame and the door leaf, various types of safety hinges have been proposed in the prior art. Among them, the folding plate on one side is fixed to the door frame by using two folding plates folded by the folding surface, The other side of the folding plate is the most used safety hinge, which is installed in a structure that is fixed to the door.

In particular, according to No. 1931961, in which the applicant of the present invention registered a patent, among the conventional safety hinges, the front end of the folding plate fixed to the door frame is provided with a fixing base that is foldably connected by a second folding surface, and is screwed and fixed. To provide a safety hinge that is mounted by pressing and pressing a separate pressure connecting rod that is foldably connected by a third folding surface to the front end of the folding plate that is fixed to the door while another fixing rod is mounted.

However, depending on the interior stationery group or the construction environment, various sizes of wide and narrow door frames are used, but conventional safety hinges can only be applied to a wide door frame, and when applied to a narrow door frame All doors have the same door width, but because the folding plate is small, it is difficult to secure a complete door width when opening and closing, and there is a problem that damage occurs to the door frame or door or moving items, as well as inconvenient problems when entering and exiting for the movement of goods.

In addition, the conventional safety hinge has a problem in that manufacturing, as well as cost, storage and handling are difficult because the component for installation is composed of several parts, and the installation structure is complicated, and thus installation is difficult.

In particular, there was a disadvantage in that the installed parts were exposed to the outside, damaging the exterior of the interior, and when the other side of the two folded plates is fixed to the door and the door frame, it is difficult to fix the exact position, so it is not fixed at the correct fixed position. If not, there are three parts to be folded, but the opening angle is changed due to the incorrect position of the part that is fixed to the door and the door frame, causing a problem that it is not easy to fold.

Therefore, in order to solve the problems of the prior art, the present invention can be installed in a wide door frame as well as a narrow door frame and secures the door width in which the door can be opened as much as possible. While making handling easier, the parts installed by the folding plate are not exposed to the outside while the door is closed, providing an excellent aesthetic.

To this end, in the present invention, while maintaining the conventional structure consisting of a first folding plate on one side of the first folding plate and a second folding plate than the first folding plate, a second folding surface is provided on the other side of the first folding plate. It is provided with a fixing base having a protruding outer wall that is extended by one end and bent at one end, so that the protruding outer wall of the fixing unit is in close contact with the door frame while the door leaf is closed so that it is mounted in the correct position. The mounting base to be mounted is in close contact so that it is always installed in the correct position, and the other side of the second folding plate is provided with a fitting cap extended by the third folding surface, and one-touch pressing and pressing the fitting cap on the mounting stand while the door is open. The folding position of the third folding surface is made to be formed on one side of the door frame adjacent to the door to be opened and closed, so that the first folding plate and the second folding plate are folded to overlap each other when the door is closed. .

Therefore, the present invention provides a smooth opening and closing structure with minimal folding by maximizing the opening and double overlapping of the folding plate covering the door gap while being able to be installed in all widths of various door frames. It is possible to provide smooth entry and exit of goods, ease of manufacturing and installation due to the simplification of parts, and low manufacturing cost, and can be installed without exposing the installed parts to the outside. It can be provided.
