Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for manufacturing a door in which a front plate is divided into an inner end panel portion and an outer peripheral frame portion.

[Prior Art and Problems to be Solved by the Invention] Today, in order to improve the quality of metal doors, some have changed the design by adding partition grooves or decorative molding members to the surface of the door, for example. In order to achieve such a configuration, the inner end plate and outer peripheral frame part of the surface plate are assembled as separate parts, but conventionally, the opposing edges of both plates were folded back or As a result, there is not enough material for the overlapped or bent parts with just a single plate-shaped face plate, so material for the end plate must be obtained from another plate material. Not only that, but the yield of materials is poor, and furthermore, it is difficult to position each member, which requires extra effort to manufacture.

[Means for Solving the Problems] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a door manufacturing method that can eliminate these drawbacks. In a door that is divided into a mirror panel part and an outer peripheral stile, the surface plate is in the form of a single plate, and after drilling intermittent long holes in the parts corresponding to the division of the plate material, the long holes are The part corresponding to the head plate and the part corresponding to the outer stile of the drilled board are integrally fixed to the reinforcing aggregate set on the back plate so that the part corresponding to the division is open, and then the continuity between each long hole is established. This is characterized in that the partition groove is formed by cutting off the section.

With this configuration, the present invention enables effective use of door materials and contributes to improvement in manufacturing efficiency.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawing, 1 is a door, and both the front side and the back side of the door 1 are formed from a front plate 2 and a back plate 5, which are each a single plate, but these front and back plates 2 , 5 are bent into a box shape, and appropriate reinforcing aggregates 7, 8, etc. are integrally fixed and incorporated between the front and back plates 2, 5 to form the door 1.
is now being configured. In addition, the front and back plates 2, 5 and reinforcing aggregates 7, 8 are all made of metal in the embodiment, and are integrally fixed using appropriate fixing means such as double-sided adhesive tape or welding. .

Incidentally, in the surface plate 2, a plurality of angular long holes 3 having a width α and a length β are intermittently bored at intervals of γ, and the long holes 3 can be used as parts corresponding to division. , the inside thereof is configured to be a portion corresponding to a mirror plate 2b, and the outside thereof is a portion corresponding to a peripheral stile 2a, and the width of the elongated hole 3 corresponds to the width dimension of the decorative molding member 10 etc. to be inserted as described later. It has been set. Then, the front plate 2 with the elongated holes 3 drilled in this way is integrally fixed to the back plate 5 to which the reinforcing aggregates 7 and 8 are fixed, but in this case, the intermediate part The reinforcing aggregate 8 is made of grooved steel having a substantially hat-shaped cross section, and is arranged so that the groove opening is located at the part corresponding to the separation, and the groove bottom is integrated with the back plate 5. It is installed in such a way that it is firmly fixed. Further, 4 is a continuous portion having a width of “α×γ” that is formed between the long holes 3, and the continuous portion 4 is configured to be cut off after being fixed to the back plate 5. As a result, a partition groove 6 is formed, which is subjected to a molding process, etc., which will be described later.

The molding member 10 is made of aluminum, for example.
A molding body 11 formed by extrusion molding of synthetic resin, etc., and having grooves approximately U-shaped in cross section on the front and back sides.
From the back side, apply a U-shaped mounting bracket 12 made of stainless steel or the like and having spring properties,
It is constructed by screwing together with a bolt 13. Further, the front side edge of the molding body 11 is bent left and right to form a flat edge-shaped flange portion 11a so as to be in close contact with the front plate 2, while a bis pocket for the bolt 13 is formed in the longitudinal direction of the back side. 11b is formed. Additionally, the mounting bracket 12 has four corner clamping portions 12a that expand toward the tip;
A locking claw 1 protrudes outward in a triangular pyramid shape at a position lower than the clamping part 12a between the clamping parts 12a.
2b is provided, and the molding member 10 is pushed into the partition groove 6 from the mounting bracket 12 side and the locking claw 12b engages with the back surface of the surface plate 2, so that the molding member 10 is attached to the surface plate 2. It is configured to be assembled into the partition groove 6 of No. 2.

In the embodiment of the present invention configured as described above, a surface plate 2 in which elongated holes 3 are drilled in advance is prepared,
Reinforcing aggregates 7 and 8 are set at predetermined positions inside the back plate 5, the front plate 2 is placed on top of the reinforcing aggregates, and the portion corresponding to the outer frame 2a and the portion corresponding to the head plate 2b are fixed by appropriate means such as adhesion or welding to form a half. After this, a partition groove 6 can be formed by cutting off the continuous portion 4 between the elongated holes 3 with a tool such as a saw, and the partition groove 6 can be processed using a molding member 10 or the like. Accordingly, the door body 1 can be formed in which the outer periphery frame portion 2a and the end plate 2b portion are separately formed. In this case, the front plate 2 including the end plate part 2b will be assembled into the back plate 5 via the reinforcing aggregates 7 and 8, so that the end plate part 2b will be fixed in a positioned state. As a result, extremely accurate positioning can be easily achieved. Moreover, the outer frame part 2a
Even if the continuous portion 4 is cut and the end plate portion 2b is separated at a corresponding part, the end plate portion 2b may be misaligned and the partition groove dimension α into which the decorative remole 10 is inserted may become uneven, or There is no need to adjust the position of the end plate portion 2b as in the conventional case.

In this way, in the present invention, even if the outer frame part 2a and the mirror plate part 2b are separated by the decorative molding 10, the mirror plate part 2b is different from the outer frame part 2b.
Therefore, the end plate part 2b can be assembled in an accurately positioned state very easily, which not only significantly improves accuracy but also greatly contributes to simplifying the assembly process. It will be possible. Moreover, since the mirror plate part 2b is constructed so that the part punched from the surface plate 2 is used as is,
Compared to conventional products, there is less material loss, and the assembly work is simpler, greatly increasing work efficiency.

It should be noted that the present invention is of course not limited to the above-described embodiment, and the distance γ between the long holes 3 can be freely set, but it may be set to a small size in consideration of the cutting work. Setting it up will make your work easier. Further, in order to prevent the decorative molding provided in the partition groove from protruding from the surface plate, the molding attachment portion may be formed into a concave groove shape with intermittent elongated holes as shown in FIG.

[Operations and Effects] In summary, since the present invention is constructed as described above, the surface plate has an outer circumferential frame portion and an inner mirror plate portion separated by a partition groove; The part corresponding to the mirror plate part is continuous with the outer peripheral frame part, and is simultaneously assembled with the part corresponding to the outer peripheral frame part to the reinforcing aggregate set on the back plate so that the part corresponding to division is opened. As a result, positioning is accurate and extremely simple, and the assembly and fixation are strong. Furthermore, in this case, the mirror plate part and the outer frame part can be molded using the same single plate material, so there is less material loss, and the partition grooved door can be manufactured easily and accurately.
