Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a mounting structure for a decorative molding for a door that is decorated on a door surface plate.

[Prior Art and Problems to be Solved by the Invention] Generally, in order to improve the quality of metal doors, a decorative molding is applied to the door surface to change the design. However, with such a structure, it is not possible to freely change the arrangement and combination of the decorative parts of the door, it is difficult to set the position of the mirror plate, or the cut part of the plate cannot be exposed, so The structure is such that the tips are folded back or overlapped with each other. As a result, if only a single plate is used, there is not enough material for the overlapping part, so the end plate must be made from another plate, resulting in poor material yield and furthermore, it is difficult to position each member. There were problems such as the extra effort required for production.

[Means for solving the problem] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a mounting structure for a decorative molding for a door that can eliminate these drawbacks. is formed in the concave groove for attaching the decorative molding of the surface plate, and the end edges of the face plate on both sides of the concave groove are extended in the direction of the surface facing each other to form a locking piece. A decorative molding fitted into a groove is provided with an engaging pawl that is elastically held at a position laterally than the edge of the locking piece, and a flange portion that covers the edge of the locking piece from the outside. The device is characterized in that the mating claws are configured to be attached and fixed by engaging with the locking pieces on the edge of the face plate from the inside.

With this configuration, the present invention can cover the cut surface of the face plate in the door body, which is manufactured by effectively utilizing materials without wasting them, and can be installed with just one push. This is what I did.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawing, 1 is a door with a decorative molding, and both the front side and the back side of the door 1 with the decorative molding have four peripheral edges bent into a box shape, and the front side has an outer peripheral frame part 2. , a mirror plate part 3 partitioned by an opening groove 4 having a groove width a and surrounded by this outer frame part 2, and a back plate 5 on the back side is a single plate. this door 1
In the case of the front side, the mirror plate part 3 is punched out from a single plate material by, for example, press punching, turret punch punching, etc., and the remaining part is used as the outer frame part 2. The opening groove 4 formed on the surface of the incorporated door body has a decorative molding 10 as described later.
is fitted so as to completely cover the entire length of the opening groove 4. Further, 6 and 7 are reinforcing aggregates which are sandwiched between the outer periphery frame portion 2 (or mirror plate portion 3) and the back plate 5 of the door 1 and are integrally fixed to the face plate. The opposing edges of the outer frame part 2 and the mirror plate part 3 extend in the plane direction so as to be narrower than the opposing spacing between the reinforcing aggregates 6 and 7, and the locking pieces 2a,
3a is formed. In addition, in this example,
Outer frame part 2, mirror plate part 3, back plate 5, reinforcing aggregate 6,
7 and the like are all made of metal, and are fixed using appropriate means such as double-sided adhesive or welding. In addition, in the figure, w
indicates a welded part.

The molding 10 is made of extrusion molded material such as aluminum or synthetic resin, and has a substantially U-shaped cross section, and has a molding body 11 having a flange portion 12 at the end edge;
A mounting bracket 20 in the form of a springy strip made of stainless steel or the like is similarly bent into a U-shape so as to cover the molding body 11 from the bottom, and a bolt 30 screws the mounting bracket 20 onto the molding body 11. It is configured. The upper end edge of the molding body 11 is bent left and right to form an expanded flat flange part 12, and the flange part 12 is adapted to come into close contact with the door face plate during installation. Further, a bis pocket 13 for a bolt 30 is formed in the longitudinal direction of the bottom. The mounting bracket 12 has clamping parts 21 at the four corners that expand toward the tip (for example, the rising angle of elevation is about 85 degrees).
An engaging pawl 22 protruding outward in the shape of a triangular pyramid is formed between the clamping parts 21 and 21 at a position lower than the clamping part 21.

In the embodiment of the present invention constructed as described above, a groove is provided on the front side of the door body in which the outer frame part 2, the mirror plate part 3, and the back plate 5 are assembled by appropriate means using reinforcing aggregates 6 and 7. An opening groove 4 having a width α is formed. In this opening groove 4, the cut surfaces of the outer circumferential stile portion 2 and the mirror plate portion 3 (ie, the locking pieces 2a, 3a) face each other while being exposed to form an edge portion of the opening groove 4. First, a plurality of mounting fittings 20 are screwed with bolts 30 into appropriate positions of the molding main body 11 cut to the length dimensions of the vertical and horizontal sides of the opening groove 4 to complete the decorative molding 1.
Assemble 0. Mounting bracket 20 for decorative molding 10
When the mounting bracket 20 is inserted into the opening groove 4, the clamping part 21 of the mounting bracket 20 is inserted between the outer frame part 2, the tip edge of the end plate part 3, that is, the locking pieces 2a, 3a, and the decorative molding 10, and at the same time, the clamping part 21 of the mounting bracket 20 The stepped portion 23 formed by the engaging claw 22 and the clamping portion 21 engages the locking piece 2a, which is the tip edge of the outer circumferential frame portion 2, and the locking piece 3a, which is the tip edge of the mirror plate portion 3, from the inside. The decorative molding 10 is fixed to the door 1 so as to completely cover the cut surface of the board. After that, necessary parts such as the lock, door scope, and screws are attached to complete the door production.

FIG. 6 shows a state in which the decorative molding 10 according to the present invention is attached, taking as an example a case where there is a step between the mirror plate part 3 and the outer circumferential frame part 2. In this case, the decorative molding main body 11 and the mounting fittings 20 may be set to dimensions that correspond to the difference in level rather than being symmetrical.

As described above, the present invention is a door in which the outer frame part 2 is manufactured by punching out the central part from a door material, and the punched inner material is used as it is as the head plate part 3, and the outer frame part 2, Even if the cut surface of the end plate portion 3 remains exposed, this cut surface can be completely covered by the flange portion 12. Moreover, the decorative molding 10 can be easily and reliably attached by a one-touch push-in operation due to the elasticity of the steel that utilizes the unevenness and other steps.

In addition, it goes without saying that by increasing the number of mounting brackets 20 installed, floating of the molding can be prevented, and although the structure can be used regardless of the door thickness, the shape of the aggregate is changed each time in order to attach the decorative molding. There's no need to do that.

[Working Effects] In short, since the present invention is constructed as described above, the decorative molding is simply fitted into the groove so that the engaging pawl is engaged with the locking piece formed in the groove from the inside. It can be installed in one piece with an extremely simple operation. Moreover, the edge of the locking piece, which is the cut surface of the plate, is covered and hidden from the outside by the flange of the attached decorative molding, so the locking piece cannot be used simply by punching out the plate. It is now possible to use a cut piece without any bending, and the surface plate can be formed by simply punching out the molding attachment part from a single plate. This not only greatly simplifies the processing and assembly process, but also greatly improves the material yield.
