Description

Door hinge device

The present invention relates to a hinge device of a hinged door, and in detail, it is possible to prevent the door edge from interfering with the stepped side of the door frame in the opening and closing of the hinged door around the hinge shaft, without damaging the aesthetics of the door. It is possible to minimize the gap between the door frames, thereby preventing a safety accident such as a child's hand or finger being pinched or cut between the door gaps.

In general, a hinge is a hardware used for attaching a door to a window, door, or furniture, and is mainly used for a hinged door that is installed on the edge of a door frame and a door and uses it as a rotating shaft to pull or push in and out.

Usually, two or three pairs of hinges, which act as rotating shafts, are used to hold the door, and handles are in and out in the middle of the opposite edge of the hinged door edge. The longer the distance between the handle on which the force acts and the rotating shaft, the more easily the door is opened.

That is, in the conventional hinged door and door frame connection structure, the hinge is fixed to one side of the door frame fixed to the wall of the building, and the hinged door is attached to the hinge so that the hinged door can be opened in one direction.

However, the opening and closing door is fixed by a hinge and opens and closes. Therefore, when the door is open, the gap between the door and the door frame is wide, so that fingers are pinched. If the door is closed, there is a risk of serious injury. .

Therefore, recently, by changing the door for the swinging door in a way that rotates in place by the hinge axis, the gap between the door and the door frame is minimized to prevent the child's hand or finger from being caught, but this is because the door rotates. It has the disadvantage that the corners of the door are caught on the upper and lower steps of the door frame.

Therefore, if the upper and lower steps of the door frame are caught, the upper and lower steps of the door frame must be removed. In this case, when the upper and lower steps of the door frame are removed, the aesthetics of the entire door are severely damaged, so the merchandise of the door is significantly reduced.

First, it should be noted that, among the drawings, the same components or parts are denoted by the same reference numerals as possible. In addition, in describing the present invention, detailed descriptions of related known functions or configurations will be omitted so as not to obscure the subject matter of the present invention.

The present invention consists of a pair of hinge devices installed at the top and bottom corners of the casement door (110).

The hinge device is composed of a hinge housing 130 having a hinge shaft 132 and a hinge housing 120 coupled to the door 110 in a state in which the hinge housing 130 is embedded, but the hinge housing ( 120) the shaft hole (121a) is perforated and extends from the shaft support portion 121 and the shaft support portion 121 having a semi-circular curved surface on the outside to support the body 131 of the hinge bundle 130, the hinge bundle ( 130) is composed of a hinged body support portion 122 having a housing shape having an opening portion 122a for insertion.

One side surface of the hinge body support portion 122 requires a vertically incised portion 123a, which is a configuration required to fix the hinge housing 120 to the door 110.

That is, the hinge body support portion 122 of the hinge housing 120 is coupled to the door 110 by a fastening screw 130a in a state fitted in the concave groove 111 of the door 110, the fastening screw ( This is because one side of the hinge housing 120 must be opened so that the tool can be inserted so that the tool can be used for the combination of 130a).

In addition, the incision (123a) is a configuration required to secure the hinge bundle 130 to the hinge housing 120. That is, a fixing screw 130b is required to fix the hinge bundle 130 to the hinge housing 120, and a configuration of the incision 123a is also required to fasten the fixing screw 130b.

After all, it is natural that the incision part 123a of the hinge housing 120 and the fastening screw through-hole 131a and the fixed screw coupling hole 131b formed in the body 131 of the hinge bundle 130 are formed to penetrate each other. .

For this purpose, the fastening screw through hole 131a and the fixed screw coupling hole 131b are also arranged at regular intervals perpendicular to the body 131, and a thread (not shown) is formed on the inner surface of the fixing screw coupling hole 131b. .

As described above, the present invention is a fastening screw (130a) is passed through the fastening screw through hole (131a) is coupled to the hinge housing 120 to the door 110, and then fixed screw that is screwed to the fixing screw coupling hole (131b) ( The hinge bundle 130 is fixed to the hinge housing 120 by 130b).

In order to support the head of the fixing screw 130b to be screwed in this way, locking jaws 123 are formed on both sides of the incision 123a. At this time, the head diameter of the fixing screw 130b should be larger than the width of the incision 123a, so that the fixing screw 130b is previously screwed to the hinge bundle 130 and the opening portion 122a of the hinge housing 120 ) To the built-in state.

This is a necessary configuration because it is difficult to connect the door 110 to the door frame B when the hinge shaft 132 protrudes outward from the hinge housing 120 from the beginning.

Between the shaft support portion 121 and the hinge body support portion 122, a stepped portion 121b is formed, which is a configuration required to engage the locking jaw 111a of the door 110. That is, the height of the shaft support portion 121 should be at least higher than the step C of the door frame B, so that the door 110 can be rotated. This step is formed constant and the stepped portion is convenient to facilitate the installation of the hinge device of the present invention. The configuration of (121b) is necessary.

As described above, the present invention does not protrude the upper and lower corners of the door 110 in a right angle shape like the conventional door 110, but is a semi-circular curved surface structure, so that even if the door 110 rotates around the hinge axis, the door 110 ) The top and bottom corners of the door frame will not have to worry about getting stuck on the steps of the door frame.

The combination of the hinge device of the present invention is as follows.

First, the fixing screw 130b is screwed into the hinge bundle 130 provided with the hinge shaft 132 in advance, and then inserted through the opening 122a of the hinge housing 120 to be embedded.

Next, insert the hinge housing 120 into the concave groove 111 of the door 110, and then use a tool such as a screwdriver to fasten the screw 130a through the incision 123a and the fastening screw through hole 131a. ).

Next, the hinge bundle 130 is raised (when the hinge axis is coupled to the top of the door frame) or lowered (when the hinge axis is coupled to the bottom of the door frame) so that the hinge axis 132 is inserted into the shaft insertion hole of the door frame (B).

As described above, when the hinge shaft 132 is inserted into the shaft insertion hole B, the fixing screw 130b coupled to the fixing screw coupling hole 131b of the hinge bundle 130 is rotated.

Accordingly, when the fixing screw 130b is rotated to retreat, the screw head is caught by the locking jaw 123 of the hinge housing 120, so that it is no longer able to retreat, and the fixing screw 130b is hinged by the reverse action 130 ) As being pushed out, the hinge bundle 130 is fixed while being firmly in close contact with the inner side of the hinge housing 120.

That is, an important technical configuration in the present invention is a structure in which the hinge bundle 130 is freely moved up and down in a state embedded in the hinge housing 120, and the hinge shaft 132 is inserted into the shaft insertion hole of the door frame B. It is to be able to fix the hinge bundle 130 in the state.

Therefore, the present invention, as shown in Figure 5, the present invention is a corner of the door 110 by the round portion 121 of the hinge housing 120 is rotated in a state that does not interfere with the step (C) of the door frame (B) It becomes possible.

As described above, although the present invention has been described by limited embodiments, the present invention is not limited to this, and is described below by the person skilled in the art to which the present invention pertains and the technical idea of the present invention. Various modifications and variations are possible within the equal scope of the claims to be made.
