Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a molding end locking tool for fixing the end of a decorative molding (hereinafter referred to as a molding) provided on a door.

[Conventional technology]

 The conventional molding was attached as follows.

That is, the front surface panel of the door is depressed by press molding to form a mounting groove portion, a double-sided adhesive tape is attached to the bottom portion of the mounting groove portion, and a molding made of aluminum or brass is bonded and attached thereto. Further, there is also a case in which the molding is directly attached to the molding through the double-sided adhesive tape without forming the mounting groove portion on the surface panel, and the molding projects from the surface panel. Further, in place of the double-sided adhesive tape, there is also a mode in which a receiving tool is provided at a predetermined pitch of the molding attachment position, and a convex portion formed on the bottom of the molding is fitted and attached to the receiving tool.

Except for the part where the door body is not edged, the molding is exposed not only on the upper and lower end surfaces of the door body but also on the door stop side end surface and the hanging end side end surface due to the design of the molding. .

[Problems to be solved by the device]

According to the conventional mall mounting structure, the mall may be peeled off when an obstacle such as a stone or a person's foot is caught or hit by the lower end surface of the door body when the door is opened or closed.
Also, when the molding is attached with double-sided adhesive tape, due to deterioration of the adhesive tape, not only the lower end surface of the door body, but also the upper end surface, the door stop side, and the hanging end side end surface It sometimes came up.

The present invention has been made in view of the above problems, and an object thereof is to provide a door molding end locking device that prevents the molding end portion from peeling or rising.

[Means for solving the problem]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention is directed to a door in which the end of the molding attached to the door surface is exposed to the end surface of the door. Is configured.

[Action]

According to this invention, when the molding end and the door main body exposed on the door end face are pinched by the elastic force of the molding end locking device, the molding end is firmly coupled to the door main body, so that, for example, when the door is opened and closed. It is possible to prevent an obstacle from being caught on the lower end surface of the door and the molding from peeling off, or to prevent the molding end from floating due to deterioration of the adhesive tape.

〔Example〕

An embodiment according to the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a lower end surface of a door and a molding end locking tool, FIG. 2 is a front view of a door body showing a mounting position of the molding end locking tool, and FIG. 3 is a cross-sectional view of the door body. FIG. 4 is a vertical cross-sectional view of the lower side of the door showing a state where the molding end locking tool is inserted.

First, the mounting structure of the molding will be described. As shown in FIGS. 1 and 3, a double-sided adhesive tape 3 is attached to a mounting groove portion 2 formed by press molding at a predetermined position of the front panel 1 of the door body A. The molding 4 having an H-shaped cross section formed by extrusion is adhered. Lower end face with the front panel 1 bent
In 1a, the corresponding portion of the mounting groove portion 2 is cut out in advance. Further, the inner frame 5 having a U-shaped cross section in the door body A is also cut out in advance. The molding 4 is such that its two parallel sides are in the vertical position and one side is bonded to the double-sided adhesive tape 3, and air spaces 4a are formed on the left and right sides in the longitudinal direction of the molding.

As shown in FIGS. 1 and 4, the molding end locking tool B is formed by bending a plate-shaped metal into a substantially U-shape. At the upper part of the molding end locking tool B, two parallel upper pressing parts 11 are formed by cutting out the intermediate part so as to be inserted into the air spaces 4a on both sides of the molding 4. The upper pressing portion 11 has its tip largely folded back upward to generate an elastic action, and is tightly inserted into the molding space 4a in a bent state.

In addition, the lower portion of the molding end locking tool B has the entire plate-shaped body for insertion into the gap between the lower side of the mounting groove portion 2 and the cutout portion of the surface panel 1 and the inner frame 5, that is, the slit portion 6. Bend in a V shape
12 is formed so as to be tightly inserted into the slit portion 6 in a bent state. The slit portion 6 may have a mode in which a single slit into which the lower pressing portion 12 is inserted is formed in a corresponding portion without using a gap in a portion where the front panel 1 or the inner frame 5 is cut out.

As shown in FIG. 2, when the molding 4 reaches the lower end from the upper end of the door body A, the molding end locking tool B configured as described above is inserted into the upper and lower end surfaces thereof, respectively, and It clamps the ends. As shown in detail in FIGS. 1 and 4, the upper pressing portion 11 is inserted into the molding space 4a and the lower pressing portion 12 is inserted into the slit portion 6 with the opening side of the molding end locking tool B first. . As shown by the phantom line, the molding end locking tool B that was in the solid line state in FIG. 4 has its upper end pressing portion 11 bent at its tip folding portion, and the lower pressing portion 12 is entirely bent, Since the molding 4 is pinched from above and below via the bottom of the mounting groove 2, the molding end is firmly coupled to the door body A. As a result, it is possible to prevent obstacles from being caught on the lower end surface of the door body and the molding from peeling off, or to prevent the molding end portion from floating due to deterioration of the adhesive tape. This mall end locking device B
Is easy to enter at the time of insertion at the folded part of the upper holding part 11 and difficult to pull out so that it will not fall off even if the mall hits an obstacle. In addition, this molding end locking tool B is easy to manufacture and easy to install, and can be applied without changing the existing molding shape.

Further, instead of the molding end locking tool, the following structure may be adopted. FIG. 5 is a perspective view of a pin-shaped molding end locking tool showing another embodiment. That is, one wire is bent symmetrically, and is formed into a substantially U-shape in side view similar to the molding end locking device of the above embodiment. This pin-shaped molding end locking device B'also has two upper parts folded back to form the upper pressing part 1
1'is formed, and the lower part is bent in a substantially V shape to form a lower pressing part 12 'so as to retain an elastic force.

In addition, in the above-mentioned embodiment, an example of attaching the molding end locking tool to the upper and lower ends of the door body is shown, but it is also possible to employ it when the molding end is exposed on the door stop side or the hanging side of the door body. Of course. Furthermore, the molding end locking device of the above-described two embodiments may be divided into left and right halves, and one may be inserted into each of the left and right air spaces of the molding. In addition, although the shape of the molding has an H-shaped section as an example, a molding having a B-shaped section may also be used for manufacturing reasons. Even in this case, the molding end locking device according to the present invention can be applied.

[Effect of device]

Since this invention is configured as described above, when the molding end and the door body exposed on the door end face are pinched by the elastic force of the molding end locking tool, the molding and the door body are firmly connected to each other, for example, opening and closing the door. Occasionally, an obstacle may be caught on the lower end surface of the door and the molding may be peeled off, and in the case of using an adhesive tape, the deterioration of the molding may prevent the molding end from rising.
