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 overlapping parts or bent parts with just a single plate-shaped face plate, so the material for the end plate must be obtained from another plate material. First, there were problems such as poor material yield and additional effort required for manufacturing.

[Means for solving the problem] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a door that can eliminate these drawbacks. In the door, the surface plate has intermittent elongated holes in corresponding parts of the partition grooves so that the end plate part and the outer peripheral frame part are separated from each other. The long holes are integrally continuous with a continuous part that can be cut off, and the part corresponding to the head plate part and the part corresponding to the outer stile of the front plate are set on the back plate so that the part corresponding to the partition groove is open. It is characterized in that it is integrally assembled and fixed to the reinforcing aggregate to form a semi-finished product of the door body.

According to the present invention, with this configuration, it is possible to accurately position the end plate portion of the door, which is divided into the outer frame portion and the end plate portion, and to improve work 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 with an interval γ between them. , the inside becomes the end plate equivalent part 2b,
The outside is configured to be a portion 2a corresponding to the outer stile, and the width of the elongated hole 3 is set corresponding to the width of a decorative molding member 10 etc. to be inserted as described later. 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 that reinforces
It is composed of grooved steel having a substantially hat-shaped cross section, and the groove opening is located at the part corresponding to the separation, and the groove bottom is integrally fixed to the back plate 5. This makes it possible to manufacture a semi-finished product of the door 1 in which the front and back plates 2 and 5 are integrated.

In addition, 4 is "α×γ" that occurs between long holes 3.
The continuous portion 4 has a width of
It is configured to be fixed to the back plate 5 and cut off after being made into a semi-finished product, and by cutting it off, a partition groove 6 is formed for performing molding processing etc. as described later. There is.

The molding member 10 is made of aluminum, for example.
A molding main body 11 formed by extrusion molding of synthetic resin, etc., and having a substantially U-shaped groove in cross section on each of 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-like flange portion 11a so as to be in close contact with the front plate 2, while a bis pocket for a bolt 13 is formed in the longitudinal direction on the back side. 11b is formed. Additionally, the mounting bracket 12 has four corner clamping portions 12a that expand toward the tip;
A locking pawl 1 protrudes outward in a triangular pyramid shape at a position lower than the gripping portion 12a between the gripping portions 12a.
2b, 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.

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 inside the back plate 5 so that the parts corresponding to the elongated holes 3 are open, the front plate 2 is placed on top of the reinforcing aggregates, and the parts 2a and 8 corresponding to the outer frame are attached by appropriate means such as adhesion or welding. By fixing the end plate equivalent portion 2b, it can be made into a semi-finished product. In this case, the surface plate 2 of the semi-finished product has a portion 2b corresponding to the end plate portion.
It is assembled into the back plate 5 via the reinforcing aggregates 7 and 8 as a single plate containing Since the parts are fixed in position, extremely accurate positioning can be easily achieved. Furthermore, after making the semi-finished product in this way, the outer frame part 2a and the end plate part 2 are
Since the continuous portion 4, which is the position corresponding to the separation with b, is cut off and separated using a tool such as a saw, the end plate portion 2b is misaligned and the partition groove dimension α into which the decorative molding 10 is inserted is uneven. 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 periphery frame part 2a and the mirror plate part 2b are separated by the decorative molding 10, the mirror plate part 2b of this semi-finished door
is integrated with the outer frame part 2a, and therefore, the end plate part 2b can be assembled very easily with accurate positioning, and the accuracy can be significantly improved. This will greatly contribute to simplification. In addition, the mirror plate part 2b has a structure in which the part punched from the surface plate 2 is used as is, so there is less material loss compared to conventional ones, and the assembly work is simple, which greatly improves work efficiency. It is something.

By the way, Figure 2, Figure 8 A, B, C, D,
When manufacturing doors with various intermittent patterns as shown in E, H, G, CH, R, and N, the intermittent patterns can be created by simply pushing the decorative molding 10 etc. into the long holes of the front plate 2. It is possible to complete a door with a decorative molding. Therefore, by varying the positions and hole pitches of the elongated holes 3, it is possible to provide doors with a wide variety of patterns. In addition, as shown in Figure 1, if you want to manufacture a door with a continuous decorative pattern molding, as shown in Figure 7B, the continuous part 4 between the long holes 3 is cut off with a tool such as a saw, and the partition grooves are cut off. However, in such a case, if the distance γ dimension between the long holes 3 is set small in advance, the cutting operation will of course be made easier.

It should be noted that the present invention is of course not limited to the above-mentioned embodiment, and in order to prevent the decorative molding provided in the partition groove from protruding from the surface plate, the molding attachment portion is shown in FIG. As shown, it may be formed into a concave groove shape with intermittent long holes.

[Operations and Effects] In short, the present invention is configured as described above, and although the inner head plate portion is separated from the outer peripheral frame portion by the partition groove, the portion corresponding to the head plate portion is By integrally fixing each of these corresponding parts to the reinforcing aggregate set on the back plate so that the parts corresponding to the partition grooves are open, in the state of an integrated single plate continuous to the parts corresponding to the outer periphery frame part,
The semi-finished product is reliably and easily assembled and fixed in an accurately positioned and reinforced state, and there is no chance of the inner mirror plate being inadvertently displaced as in the conventional case.

Furthermore, the end panel and the outer frame part are made of the same single plate material, and the continuous part can be cut off to form a continuous molding type, or the continuous part can be left uncut and an interrupted molding type can be used. Furthermore, by changing the position and pitch of the long holes, it is possible to provide doors with a wide variety of patterns at will. Furthermore, since the end plate part is formed from a single plate common to the outer periphery frame part, material loss can be minimized and the width of the partition groove can be precisely determined.
