Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a door mounting device, and particularly to one that improves the engagement between a mullion and a vertical frame.

(Prior Art) A door mounting device is generally constructed by fixing one mounting piece of a hinge to the door side and fixing the other mounting piece to a vertical frame, and on the back side of the other mounting piece, Usually, a screw holder is provided.

(Problem to be solved by the invention) Therefore, the door opens and closes while being supported by the vertical frame via the hinge.

In this case, there is no problem if the vertical frame is securely nailed to a pillar or the like for support, but there is a problem if the vertical frame is engaged with the mullion, for example in the manner shown in Figure 2. .

In the door mounting device shown in FIG. 2, a vertical frame 5 to which one mounting piece 2 of a hinge 1 is fixed is engaged with a mullion 6 in a simply fitted state. Specifically, one side wall 51 of the vertical frame 5 is inscribed in the mullion 6 via the tight material 9, and the edge of the other side wall 52 of the vertical frame 5 is connected to the protruding edge 61 of the mullion 6 and the mullion piece 7. It has a simple structure of being held between the edges. in this way,
The structure A in which the vertical frame 5 and the mullion 6 are engaged can be easily assembled by simply fitting the two 5 and 6 together, but on the other hand, since the load of the door 4 is applied to the vertical frame 5, the structure A has a long length. When used for a long time, the state of engagement between the vertical frame 5 and the mullion 6 becomes uncertain, causing a situation where the door 4 also tilts as a unit, and as a result, the door 4 aligns precisely with the door frame (not shown). This causes an inconvenience in that opening and closing of the door 4 is hindered.

The present invention is a door mounting device that does not cause any trouble in opening and closing the door 4 even when applied to the above structure A in which the vertical frame 5 and the mullion 6 can be easily engaged and assembled using the screw holder 8. This was done for the purpose of providing.

(Means for Solving the Problem) That is, the door mounting device of the present invention inscribes one side wall of the vertical frame into one side wall of the mullion, and clamps the edge of the other side wall of the vertical frame between the mullion and the mullion piece. A door mounting device that is applied to a structure that is assembled at least, one mounting piece of the hinge is fixed to the door, and the other mounting piece is screwed to the vertical frame provided with a screw holder on the back surface, and further, The screw holder is formed to protrude toward the side of the mullion, and an end edge of the screw holder is engaged with an engagement groove formed in the mullion.

The direction of engagement between the edge of the screw holder and the mullioned engagement groove may be any direction other than the direction in which the vertical frame comes out.

(Function) According to the above structure, the edge of the screw holder is engaged with the engagement groove of the mullion, and the vertical frame is prevented from coming off from the mullion, so that the door does not tilt. Also,
In the above configuration, only the cross-sectional shape of the screw holder is made into an L-shape, for example, and the shapes of other members are not changed, so there is no increase in the number of parts. Further, the vertical frame and the mullion can be easily combined and connected by fitting as in the conventional case.

(Example) The present invention will be explained below with reference to FIG.

FIG. 1 is a cross-sectional view showing an embodiment of the present invention, in which the same reference numerals as those used in FIG. 2 indicate the same or corresponding parts.

As is clear from the comparison between FIG. 1 and FIG. 2, in the present invention, the cross-sectional shape of the screw holder 8, the shape of the vertical frame 5, and the manner in which the screw holder 8 engages with the vertical frame 5 are different.

That is, the upright piece 81 is connected to the screw holder 8, and the engagement groove 62 is formed at the appropriate position of the mullion 6.
The end edge 82 of the screw holding upright piece 81 is inserted into this engagement groove 62.
In this example, the upright piece 81
is L-shaped, and is connected to the screw holder 8 so that the overall shape is approximately U-shaped. On the other hand, the engagement groove 62 is formed in the hollow part 6 of the mullion 6.
3 by forming an L-shaped outward protrusion 64 at the corner. And preferably,
Another engagement groove 62 may be formed symmetrically at the corner of the hollow portion 63. This is because by doing so, it becomes possible to form the door either on the left or the right.

However, it goes without saying that the upright piece 81 is not limited to the above-mentioned shape; for example, as shown by the two-dot chain line in FIG. The matching groove 62 can also take any form, such as being formed as shown by the two-dot chain line, in short, the screw retainer 8
Any form may be used as long as the upright piece 81 is connected to the mullion 6, an engagement groove 62 is formed in the mullion 6, and the upright piece 81 is engaged with the engagement groove 62.

Furthermore, the mullion 6 and the left and right vertical frames are fixed by mullion pieces 7, and the vertical frame 5 is also supported and fixed by the screwing of the concealment case 10.

In the illustrated drawing, a twist prevention piece 11 is disposed inside the vertical frame 5 in order to prevent the vertical frame 5 from twisting.

(Effects of the invention) As explained above, the invention has one side wall of the vertical frame inscribed in one side wall of the mullion, and the edge of the other side wall of the vertical frame is sandwiched between the mullion and the mullion pieces. A door mounting device applied to a structure to be assembled, wherein one mounting piece of the hinge is fixed to the door, and the other mounting piece is screwed to the vertical frame provided with a screw holder on the back surface, and A screw grip is formed to protrude toward the side of the mullion, and an edge of the screw grip is engaged with an engagement groove formed in the mullion,
The vertical frame can be assembled into a mullion simply by fitting, and there is no increase in the number of parts, and above all, the screw holder is engaged with the mullion, so the vertical frame does not tilt with respect to the mullion. Therefore, there is an advantage that no situation arises that hinders the opening and closing of the door.
