DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for curing an opening / closing door such as an entrance door, a service door, a gate, and the like, and a cured opening / closing door.

[0002]

2. Description of the Related Art An opening / closing door is a substantially plate-like body having a predetermined thickness, width and length. At an installation site, a hinge is attached to one side in the width direction, and a lock is attached to the other side in the width direction. Then, the hinge is connected to the fixed side to be freely opened and closed.

[0003] Since the opening / closing door is assembled in a factory or the like and transported to an installation site, it is cured so as not to be damaged during the transportation.

[0004] For example, an opening / closing door is inserted into a bag larger than an opening / closing door made of a shrink film which contracts in two axial directions, that is, a longitudinal direction and a lateral direction, and the shrink film is heated in the longitudinal and lateral directions by heating the whole. And the entire door is covered with a shrink film.

[0005] Further, a tape is attached to the entire surface of the door, and the entire door is covered with the tape.

[0006]

In order to mount the door at the installation site, hinges and locks are attached to one side and the other side in the width direction of the door as described above. Since the tape is in the way, hinges and locks are attached after removing the shrink film and the tape.

As described above, when the shrink film and the tape are all peeled off from the door, the entire surface of the door is exposed, and may interfere with the fixed side or the like during installation and may be damaged.

Further, the building may not be completed at the time when the opening / closing door is attached due to the order of construction of the building or the like.
If the opening / closing door is left with the entire surface exposed, the door may be deteriorated or damaged by wind and rain.

For this reason, conventionally, after the hinges and locks are attached, the opening / closing doors are re-cured with cardboard paper or the like to prevent damage at the time of attachment, and are deteriorated or damaged during the period from attachment to completion of the building. And re-curing work after attaching the hinge and the lock becomes troublesome.

In order to solve this problem, only the hinge attachment portion and the lock attachment portion of the shrink film or tape need to be peeled off. However, in order to do this, the shrink film or tape is cut off by a cutter or the like. It is not practical because the peeling work is troublesome and the surface of the opening / closing door may be erroneously damaged.

Accordingly, an object of the present invention is to provide a cured opening / closing door and a method of curing the opening / closing door which can solve the above-mentioned problems.

[0012]

Means for Solving the Problems A substantially plate-like body having a predetermined width, thickness and length, having a hinge mounting portion 9 on one side 8 in the width direction and a lock mounting portion 11 on the other side 10 in the width direction. A cured opening / closing door, comprising a curing film covering a surface of the opening / closing door other than a middle portion in the longitudinal direction of one widthwise side portion 8 and another widthwise side portion 10.

An opening / closing door 1 which is a substantially plate-like body having a predetermined width, thickness and length and has a hinge mounting portion 9 on one side 8 in the width direction and a lock mounting portion 11 on the other side 10 in the width direction. In a method of curing by covering with a curing film, the heat-shrinkable film that contracts in the width direction by heating is used to form the opening / closing door 1.
The opening / closing door 1 is inserted into a bag-shaped curing film 20 which is wider and longer and both ends in the longitudinal direction are closed and both ends in the width direction are open, and the bag-shaped curing film 20 is heated in this state. A method for curing an opening / closing door that shrinks in the width direction to adhere to the surface of the opening / closing door 1.

In the case of the cured door for opening and closing according to the present invention, the curing film does not cover one side in the width direction and the other side in the width direction of the opening and closing door. Hinge and lock can be attached, and there is no need to re-cure after attaching.

According to the curing method of the present invention, the opening / closing door 1 is inserted into the bag-shaped curing film 20 and heated to leave a longitudinally intermediate portion on one side in the width direction and on the other side in the width direction. The other surface can be covered with a curing film, and the curing operation is simplified.

The one-side curing film 21 and the other-side curing film 22 of the bag-shaped curing film 20 are largely shrunk in the width direction by heating and hardly shrunk in the longitudinal direction (for example, the shrinkage in the width direction is set to 100). Sometimes the longitudinal shrinkage ratio is 20 to 30) Uniaxially shrinkable heat-shrinkable film, for example, formed by cutting a continuous long heat-shrinkable film by folding it from a predetermined length and welding the cut edge. .

The opening / closing door 1 is inserted into the bag-shaped curing film 20 so that both ends of the bag-shaped curing film 20 in the width direction project from the one end surface 4 and the other end surface 5 in the width direction of the opening / closing door 1. The bag-shaped curing film 20 is heat-shrinked by heating the whole in this state.

The one-side curing film 21 and the other-side curing film 22 of the bag-like curing film 20 largely shrink in the width direction, but hardly shrink in the longitudinal direction. Therefore, as shown in FIG. As shown in FIG. 2 and FIG. 3, the longitudinally intermediate portions of the two end surfaces 21 a, 22 a of the one-side curing film 21 and the other-side curing film 22 are one end surfaces in the width direction of the opening / closing door 1. 4, the other end face in the width direction 5
More closely to the center in the width direction than to the one side surface 2 and the other side surface 3 of the opening / closing door 1, and both ends 23 in the longitudinal direction of the bag-shaped curing film 20 are arranged in one end surface 6 in the longitudinal direction of the opening / closing door 1. The other end face 7, the one end face 4 in the width direction, and the other end face 5 are in close contact with both ends in the longitudinal direction, respectively.

Further, the one-side curing film 21 and the other-side curing film 22 contract in the width direction to form a large number of wrinkles continuous in the longitudinal direction in the width direction as shown in FIG. The surface on one side and the surface on the other side have a shape having a large number of concave portions and convex portions continuous in the longitudinal direction over the width direction.

Because of this, the cured opening / closing door 1
As shown in FIG. 2, the surface other than the hinge mounting portion 9 and the lock mounting portion 10 is covered with a curing film.

Therefore, as shown in FIG. 4, the hinge 30 and the lock 31 can be mounted at the mounting site without peeling the curing film, and after the hinge 30 is mounted on the vertical frame 33 of the door frame 32, the hinge 30 can be mounted. Almost the entire surface of the door 1 can be covered with a curing film.

Next, a device for curing the door 1 will be described. As shown in FIG. 5, a first transport unit 40, a second transport unit 41, a heating unit 42, and a third transport unit 43 are sequentially provided in the transport direction, and the first, second, and second transport units are provided. 3 transport section 4
