Description

[Detailed Description of the Invention] The present invention relates to an airtight device for a door frame, which is constructed by butting and joining the upper end of the vertical frame and the side end of the upper frame at approximately 45 degrees.

In recent years, the end connections between the upper frame made of extruded aluminum and the left and right vertical frames are as shown in Figure 6.
In order to maintain the concavo-convex pattern on the surface, both ends are beveled at approximately 45 degrees and butt-joined. However, a doorstop wall 3 that also serves as an airtight wall is provided on the inside surface of the vertical frame 1, and when the end of the vertical frame 1 is cut diagonally, the upper end of the doorstop wall 3 is also cut diagonally, and the vertical frame 1 and the doorstop wall 3 are cut diagonally. The end of the upper frame 2 is connected by forming a triangular gap 4 above the cut edge of the door stop wall 3, as shown by dotted lines.
was formed, deteriorating the appearance. On the other hand, it is also possible to horizontally cut the upper end of the door stop wall 3 so that it contacts the lower surface of the upper frame 2, but it is also possible to perform two cutting processes, diagonal cutting and horizontal cutting, on the end of the vertical frame 1, which is a form material. However, the machining accuracy was poor and the machining was troublesome, resulting in a significant decrease in work efficiency.

The present invention was made in view of the above points, and the entire upper end of the vertical frame is cut diagonally, and the gap between the cut edge of the door stop wall and the upper frame created by this diagonal cutting is appropriately filled. The present invention proposes an airtight device for a door frame that easily prevents the appearance of the door frame from deteriorating by closing it with a closing material.

Embodiments of the present invention will be described below based on the drawings. FIG. 1 is a front view of the apparatus of this embodiment, FIG. 2 is a sectional view taken along the line A-A in FIG.

In each of the above figures, the door frame airtight device according to the present embodiment connects the upper end of the vertical frame 1, which has the doorstop wall 3 which also serves as an airtight wall on the inner surface, and the side end of the upper frame 2 to each other. In a door frame formed by butting each other at approximately 45 degrees, a decorative cover portion 6 is attached to the door stop wall 3 in a manner surrounding the wall 3, and a door is provided on one side of the decorative cover portion 6. A closing material 5 is constructed from the hit buffer section 7, and the upper end of the said closing material 5 is connected to the door stop wall 3.
The lower end surface 2a of the upper frame is rolled upward from the cutting edge of the upper frame.
It is configured to abut against the upper frame lower end surface 2a and the upper end surface of the door stop wall 3 so as to cover the gap 4.

The closing material 5 is applied to the entire length of the door stop wall 3 in order to cover the gap 4 at the top of the door stop wall 3. For example, when it is installed in a transom, it is formed at approximately the same height as the transom height. However, if it is installed on a frame without a transom, it will be installed over the entire length from the top frame to the bottom frame. Further, as the material of the closing member 5, an elastic material such as synthetic resin or rubber is used. For example, by double extruding the decorative cover part 6 with hard synthetic resin and the doorstop buffer part 7 with soft synthetic resin, the decorative cover part 6 can be firmly attached to the doorstop wall 3, and the doorstop buffer part 7 can be firmly attached to the doorstop wall 3. The impact buffering portion 7 has sufficient elastic force and can buffer the impact of the door 8.

Next, as for the closing material 5, the decorative cover part 6 is attached to the door stop wall 3.
It has an internal shape that is substantially the same as the external shape of the door stop wall 3 so as to surround the door stop wall 3, and has a projection 6a of the same shape that fits into the tight material storage recess 3a of the door stop wall 3. The hit buffer part 7 is the decorative cover part 6
On the side surface facing the door 8, several protrusions 7a are arranged in parallel in the longitudinal direction. As mentioned above,
By providing the decorative cover part 6 with a protrusion 6a having the same shape as the tight material storage recess 3a, the decorative cover part 6
The doorstop can be attached to the wall 3 with more integrity. In addition, the covering piece 6b provided on one side of the decorative cover portion 6 serves as a decorative edge by covering the entire surface of one side of the doorstop wall 3, and as shown in FIG. By bending the gap 6c, the inward elasticity can be increased and the covering of the doorstop wall 3 can be made even stronger. Furthermore, a protrusion 6d is formed at the inner tip of the adhered piece 6b, and by pressing this into contact with the door stop wall 3, the entire adhered piece 6b is stretched in an arched shape, thereby increasing the pressing elasticity. Furthermore, by configuring the door stop buffer section 7 by arranging several protrusions 7a in parallel, the impact of the door 8 coming into contact with it can be further buffered.

FIG. 5 is a plan view of another embodiment of the closing material, and the closing material 5 shown in the figure is formed with a triangular projection 6a that fits into the tight material storage recess 3a.
The elastic force of a and the enveloping force of the entire decorative cover part 6 ensure that it is firmly attached to the door stop wall 3. Moreover, the door stop buffer part 7 has a large number of protrusions 7a to improve airtightness. Note that the protrusion 6a of the decorative cover portion 6 is located in the recess 3a of the doorstop wall 3.
It can be modified as appropriate depending on the shape.

The above-mentioned closing material 5 is installed by sliding it from the longitudinal direction into the door stop wall 3 of the vertical frame 1 whose upper end is cut at approximately 45 degrees, and fits into the triangular gap 4 shown in FIG. In a state where the upper end of the closing member 5 is positioned, the upper end of the vertical frame 1 and the side end of the upper frame 2 are butted against each other at approximately 45 degrees to form a frame.

As described above, the present invention is configured such that the closing material consisting of the decorative cover part and the door stop buffer part is attached to the door stop wall of the vertical frame, so that the upper end of the vertical frame and the side end of the upper frame are The gap at the top of the door stop wall that occurs when the doors are butt-joined at approximately 45 degrees to each other is covered by the upper end of the closing material, thereby easily and reliably preventing deterioration in appearance. can. Furthermore, since the closing material is provided with a door stop buffer on one side, it reliably prevents the impact of the door from coming into contact with it, and in combination with the shielding of the gap, further improves the airtightness when the door is closed. I can do it.
