Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a wooden door using a paper honeycomb plate or other plate-like body as a base material, and its field of use is for openings in buildings. It is mainly used for doors as opening/closing members, and is widely applied to other similar items, such as doors for furniture such as chests of drawers and storage devices.

[Prior art]

Doors using flat paper honeycomb as a base material are conventionally known.

FIG. 5 shows a cross-sectional structure of this type of door (hereinafter referred to as "prior art"). Here, A is a paper honeycomb, B is a surface material adhesively bonded to both sides of the paper honeycomb, C is a frame material as a frame, and D is a picture frame material.

In this structure of the prior art, the paper honeycomb is weak in strength, so the strength depends on the stile material, and the stile material is thick, making the door as a whole unnecessarily heavy. It becomes something.

In addition, the adhesive surface between the outer surface of the paper honeycomb plate and the frame material is extremely small, and the adhesive and fixation is mainly done by the frame material interposed between the two, so the fixing force of the paper honeycomb is It cannot be said that it is strong enough to withstand the impact force, and the door body lacks strength as a whole.

Furthermore, paper honeycomb has the advantage of being inexpensive because it is a mass-produced product with constant quality, but in this conventional technology, only a portion of the entire door is used, and the advantages of paper honeycomb are not fully utilized. The problem is that it is not being utilized.

In addition, when looking at the manufacturing process of doors, assembly must be performed continuously, and if the dimensions of the door, especially the dimensions of the frame, change, the dimensions of each component must be changed accordingly, and the processing time and labor required for each component changes. It has been pointed out that it takes a lot of time.

The structure of the door core 1 is shown in FIGS. 1 and 2. The door core 1 is made up of a flat plate base material 2, a frame material 3, and a sill material 4.

The plate-shaped base material 2 is a rectangular plate of equal thickness, and is formed by cutting, for example, a large paper honeycomb material into an appropriate size according to the required dimensions of the door. 2a is a notch for attaching a lock or a door handle.

For example, cross plywood is used as the frame material 3, and is attached to the outer edges of the four circumferences of the plate-like base material 2 in accordance with the thickness of the plate-like base material 2. A relatively thin width (about 3 cm) of the frame material 3 is sufficient. The frame material 3 has a function of preventing the plate-shaped base material 2 from warping.

The lining material 4 has a required thickness and width, and is adhesively bonded (attached) across the plate-like base material 2 and the frame material 3 via an adhesive. That is, an adhesive is applied to the entire surface of one side of the lining material 4 to integrally join the plate-like base material 2 and the frame material 3. The waste upholstery material 4 is the upper upholstery material 4
It consists of a, lower upholstery 4b, and both side upholstery 4c. Although the strip material 4 is normally arranged on both sides of the plate-shaped base material 2, it is not prohibited to arrange it only on one side. As the lining material 4, cross plywood is usually used.

Therefore, both side parts (or one side part) of the door core 1
In the center, there is a rectangular recess 1A surrounded by sapling material 4.
is formed. indicates the width of the recessed portion 1A in the lateral direction.

3a and 3b show the frame panel 5 fitted into the recess 1A of the door core 1. The frame panel 5 consists of a panel 6 and a frame 7.

The panel 6 is made of a thin plate-like surface material that is fitted into the recess 1A of the door core 1.

The frame 7 is fixed to the outer edge of the panel 6 on all four sides, and its back side engages with the shoulder of the upholstery material 4.

FIG. 4 shows a cross-sectional view of the completed door by attaching the frame panel 5 to the door core 1.

Reference numeral 8 denotes a peripheral surface member as a decorative material attached to the surface of the upholstery material 4, and usually cross plywood is used. The peripheral surface member 8 is attached prior to attaching the frame panel 5 to the door core 1. Note that the surface member 8 can be omitted if the surface of the upholstery material 4 is sufficiently smooth and beautiful;
This can also be omitted by painting the surface of the lining material 4.

It is affixed to both side edges of the door core 1 and across the frame material 3, the sillage material 4, and the peripheral surface member 8.

It goes without saying that when the upholstery material 4 is placed on one side of the door core 1, a surface material (decorative material) covering the entire surface of the other side is attached.

Incidentally, the specifications of the door core and the door are illustrated.

The plate-shaped substrate 2 of the door core 1 has a height of 1925 mm, a width of 637 mm,
The thickness is 18mm, and the frame material 3 has a width of 30mm and a thickness of 18mm.
mm, and the thickness of the sakuhari material 4 is 6 mm, and its width is 151 mm for the upper sakuhari material, 186 mm for the lower sakuhari material,
The lining material on both sides is 104mm. Therefore, the width of the recessed portion of the door core 1 is 527 mm. In addition, the peripheral surface member 8
is pasted with the same width as sakuhari material 4, but its thickness is
Take 2.5mm.

Next, a method of manufacturing the door of the above embodiment will be described. There are various implementation methods, but the following example shows an embodiment for a single type (large quantity) of both the door core and the frame panel.

The steps will be described below in order.

(1) Door core 1 is manufactured as follows. That is, a flat paper honeycomb is cut into required dimensions corresponding to the predetermined dimensions of the door, and the plate-shaped base material 2 is obtained. Cross plywood is cut to a predetermined thickness (that is, the thickness of the paper honeycomb) and used as the frame material 3, and the frame material 3 is attached to the outer four circumferences of the plate-like base material 2 (both are glued together). (Although it is not necessary to do so, you may feel free to secure it lightly with a fixing device such as a nail). Next, a lining material 4 having a required thickness and width is fixed across the plate-like base material 2 and the frame material 3 via an adhesive. The strip material 4 is placed on one or both sides of the plate-like base material 2.

(2) If necessary, attach a peripheral surface material 8 as a decorative material to the surface of the upholstery material 4.

(3) Attach pusher materials 9 to both outer peripheral surfaces of the door core 2. Prior to pasting the main material 9, the outer edges of the four circumferences of the door core 1 are cut (or cut) to form a smooth surface.

(4) On the other hand, prepare a panel 6 that matches the recess 1A formed inward of the lining material 4 of the door core 1, fix a frame 7 around the four sides of the panel 6, and Manufacture. One type of panel 6 is selected from among those in a flat plate shape or one with irregularities, and one type of frame 7 is selected from among those in a square shape or a round shape.

This step is carried out in parallel with step (1).

Note that the door core 1 and frame panel 5 manufactured by the steps (1) and (4) above are stored as appropriate.

(5) Fit the frame panel 5 produced in step (4) into the recess 1A of the door core 1 produced in steps (1) to (3), and fix the frame panel 5 using appropriate fixing means (usually (can be fixed with adhesive, nails, or screws).

Through the above steps, the production of the door body is completed.

In the above embodiment, both the door core and the frame panel are of a single type (in large quantity), but the following embodiments are adopted depending on the form of the door.

When there are many different dimensions of the door (width, height, thickness), the size of the frame panel changes, and there are many different shapes of the frame panel (the shape of the frame and the shape of the panel). , door cores and frame panels are both produced in a wide variety of products (in small quantities).

When the size of the door is the same but there are many types of frame panels, the door core is produced in a single type and in large quantities, and the frame panels are produced in many types and in small quantities.

That is, many types of frame panels are prepared in advance depending on the type, and the door is completed by fitting them into the recess of a single door core.

When there are many door dimensions but only a single frame panel, it is possible to prepare many types of door cores in advance according to the type, and fit the frame panels produced in large quantities of a single type into the recesses of each door core. Put it on and complete the door.
