Description

  The present invention relates to a door in which a core material and a bag are sandwiched and joined between front and back panels used for an entrance or the like.

  The entrance door has a core made of polystyrene foam or the like on the inside of a metal frame consisting of a metal upper frame, a lower wall, and left and right walls, and a panel made of steel or the like on the outdoor side and indoor side surfaces of the frame and core material. Are bonded with an adhesive. When the door is exposed to solar radiation, the outdoor panel tends to extend greatly in the vertical direction due to heat, and the indoor panel is insulated by the core material, so it hardly extends, and these outdoor and indoor panels are assembled. Therefore, the door is warped so that the middle part in the vertical direction swells to the outdoor side. The amount of warpage is greater on the free door end side than on the hanging side fixed to the fence frame with a hinge. Inside the door on the door end side, a lock with a dead bolt and a latch bolt is embedded, and the door is locked by engaging the dead bolt and the latch bolt with the hole of the lock receiver of the frame. When the door is warped as described above, the dead bolt and the latch bolt are not easily engaged with the lock. When locking manually, even if the door is warped, the resident could lock it by operating the lock while pulling it against the room with the handle, but in recent years electronic locks have become widespread, In the case of an electronic lock, since it is operated by a remote controller from a position away from the door, there are many problems that the dead bolt does not engage with the lock receiver.

As a conventional structure for preventing the door from warping due to heat, there is a structure disclosed in Patent Document 1. In this door, the expected size of the braid is smaller than the expected size of the core, and the outdoor panel is joined to the outdoor side of the braid with adhesive, but the indoor panel is attached to the indoor side of the braid. Not joined. A heat insulating panel and a positioning resin block serving as spacers are disposed between the indoor side surface of the pair of panels and the indoor side panel. This door suppresses the warpage of the door caused by the difference in thermal expansion between the outdoor side panel and the indoor side panel because the indoor side panel is not joined to the frame.
However, in the above door, the edge of the panel on the indoor side is not temporarily joined to the frame, and is only partially temporarily fixed via the heat insulating panel and the positioning resin block. There is an inconvenience. Furthermore, it is necessary to affix the heat insulation panel on the side of the interior of the frame with double-sided tape, or to attach the positioning block to the frame, which is very time-consuming to manufacture the door. Also, because the expected dimensions of the braiding and the core material are different, the dimensional tolerance of each member so that the sum of the expected dimensions of the braiding and the spacer (heat insulation panel, positioning block) matches the expected dimensions of the core material. Need to manage.

The entrance door includes a door frame 15 and a door 14 attached to the door frame 15 with a hinge 16 so as to be freely opened and closed.
As shown in FIG. 2, the door 14 includes a vertically long handle 12 at the middle in the vertical direction on the door end side, and the locks 10 a, 10b. A door guard 11 is provided on the door side on the indoor side surface at a position slightly higher than the upper locking lock 10a. The upper and lower final locking locks 10a and 10b are electronic locks that can be locked and unlocked by a remote controller in addition to a key and a thumb turn. By operating the remote controller or the like, the dead bolt 17 appears and disappears from the door end side. The door 14 is locked by engaging with a lock receiver 19 provided on the inner peripheral side surface of the collar frame 18 (see FIG. 4). The lock receptacle 19 is formed so that the hole with which the dead bolt 17 engages is slightly larger than the dead bolt 17, and the mounting position can be adjusted in the indoor and outdoor directions. The door guard 11 is capable of restricting the opening range of the door 14 to a predetermined narrow range by hooking the arm on the receiving metal 20 provided on the frame 18. The base portion of the handle 12 is provided with a latch lock (not shown). A door closer 24 is provided at the upper part of the indoor side surface of the door 14. A window portion 22 incorporating a glass 21 is provided vertically at the center of the door 14.

  As shown in FIGS. 3 and 4, the door 14 includes panels 1 a and 1 b made of thin steel plates on the outdoor and indoor surfaces, and between the outdoor and indoor panels 1 a and 1 b inside the door. A core material 2 made of a foamed polystyrene board is provided in a sandwiched manner, and an upper rod 3, a lower rod 4, a door rod 5 and a hanging ridge rod are provided between the panels 1a and 1b so as to surround the periphery of the core material 2. 6 is provided. The upper eaves 3 and the lower eaves 4 use extruded shapes of synthetic resin, and as shown in FIG. 3, have an approximately U-shaped cross section with an inner peripheral side opened. The door rod 5 and the hanging rod 6 are made of an aluminum alloy extruded shape and have a substantially U-shaped cross section with an inner peripheral side opened. The expected dimensions of each of the flanges 3, 4, 5, 6 are the same as the expected dimensions of the core material 2.

  As shown in FIG. 4, a wooden block body 13 is provided inside the door at a position where the door guard 11 is attached, and the door guard 11 is firmly attached by screwing wood screws 23 into the block body 13. Similarly, a wooden block body 25 is provided inside the door where the door closer 24 is attached. As shown in FIG. 5, the core material 2 is provided with notches 26 corresponding to the positions where the block bodies 13 and 25 are disposed and the positions where the upper and lower final locks 10 a and 10 b and the handle 12 are attached. .

  As shown in FIGS. 3, 4, and 6, the window portion 22 has openings 27 having the same shape on the outdoor side and indoor side panels 1 a and 1 b and the core member 2, and sandwiches the glass 21. A frame 28 and 29 are fitted into the outer wall 27 and the indoor side 27. The frame 28 on the indoor side has a rectangular frame shape, and the frame 29 on the outdoor side has an aluminum panel 29b provided between the left and right vertical members 29a, 29a. The design of the portion 22 is different between the indoor side and the indoor side. The frame 29 on the outdoor side and the frame 28 on the indoor side are coupled with screws 30 from the indoor side, and a cover 31 is attached to the frame 28 on the indoor side to hide the screws 30.

The panel 1b on the indoor side is bonded entirely to the core material 2, the inner side surfaces of the flanges 3, 4, 5, 6 and the block bodies 13, 25 with an adhesive.
On the other hand, as shown in FIG. 1, the outdoor panel 1a is provided with non-adhesive regions 7a and 7b at the upper and lower portions on the door-end side. 5, 6 and the outdoor side surfaces of the block bodies 13, 25 are bonded with an adhesive. A hatched area 32 indicates an adhesion area. The upper non-adhesion region 7a extends from the upper edge of the panel 1a to the top of the block body 13 corresponding to the attachment position of the door guard 11, and the lower non-adhesion region 7b is the attachment position of the lower locking lock 10b from the lower edge of the panel 1a. As below. The upper non-adhesion region 7a and the lower non-adhesion region 7b have a width w extending from the door-side edge of the panel 1a to the door-end collar 5 and the core material 2. The width w of the upper non-adhesion region 7a and the lower non-adhesion region 7b is substantially the same as the width necessary for attaching the handle 12, the lock locks 10a and 10b, the latch lock, and the door guard 11 (strictly speaking, the width w A little larger than). Specifically, the upper non-adhesion region 7a has a width w of 130 mm and a height h1 of 710 mm, and the lower non-adhesion region 7b has a width w of 130 mm and a height h2 of 500 mm. . The panel 1a has a width of 824 mm and a height of 2310 mm. That is, the non-adhesive regions 7a and 7b occupy more than half of the total height of the door 14 at the door end.

  As shown in FIG. 4, an edge member 8 made of an aluminum alloy extruded shape is provided on the door side surface of the door 14 over the entire height. The edge member 8 has a finding piece 9 that abuts against the surface of the door-side edge of the outdoor panel 1 a over the entire length, and the outdoor piece panel 1 a includes the finding piece 9 and the door-end fence 5. By sandwiching the edge on the door-end side, the edge on the door-end side of the outdoor panel 1a that is not bonded is prevented from floating. There is no such finding piece on the indoor side of the edge material 8 and is flush with the surface of the panel 1b on the indoor side, so that the tight material 33 attached to the frame 18 is not damaged.

  Next, the manufacturing procedure of the door 14 will be described. First, as shown in FIG. 5, an adhesive is applied to the back surface of the outdoor panel 1a except for the upper non-adhesive region 7a and the lower non-adhesive region 7b. The application of the adhesive is automatically performed by the machine, and the brush to which the adhesive is applied strokes the entire back surface of the panel 1a. In the region 32 to which the adhesive is applied, the adhesive comes out of the brush, In the upper non-bonding area 7a and the lower bonding area 7b, the adhesive is set so as not to come out from the brush. Next, the block bodies 13 and 25, the flanges 3, 4, 5 and 6, and the core material 2 are placed on the back surface of the outdoor panel 1 a coated with an adhesive. After that, an adhesive is applied to the entire back surface of the indoor panel 1b and placed on it. Then, the door 14 is pressed from the front and back with a press machine, and the panels 1a and 1b are firmly bonded. Thereafter, the edge member 8 is attached to the door side surface of the door 14, and the glass 21 and the frames 28 and 29 are fitted and attached to the opening 27 as shown in FIG. 6. Finally, the locks 10a and 10b, the handle 12, the door guard 11, and the door closer 24 are attached.

As described above, the door 14 is bonded to the door-side portion of the outdoor panel 1a only in the middle portion in the vertical direction where the handle 12, the door guard 11 and the like are arranged, and the upper portion above and below the upper portion. Since the non-bonding region 7a and the lower bonding region 7b are not bonded to the flanges 3, 4, 5 and the core material 2, the upper non-bonding region 7a and the lower bonding region 7b freely extend vertically when exposed to sunlight. Therefore, it is possible to reduce the warpage of the door 14 on the door end side. By reducing the warpage on the door end side, even when electronic locks are used for the lock locks 10 a and 10 b, it is possible to effectively suppress the occurrence of a problem that the dead bolt 17 does not engage with the lock receiver 19. Moreover, since the edge part of the door end side of the outdoor side panel 1a is clamped by the finding piece 9 of the edge member 8 and the door end rod 5, the upper part of the door side of the outdoor side panel 1a which is not bonded. And the bottom does not rise. Further, the door 14 can be manufactured in the same manner as a normal door by simply applying no adhesive to the upper and lower non-adhesive regions 7a and 7b of the outdoor panel 1a. Since the expected dimensions of 6 and the core material 2 are the same, and there is no need to install a spacer, manufacturing is easy.
Furthermore, the door 14 has a width that the upper non-adhesion region 7a and the lower non-adhesion region 7b extend over the door toe 5 and the core material 2, so that the door 14 is warped as compared with the case in which only the door toe 5 is not adhered. The effect of preventing is high. In addition, since the width w of the upper non-adhesive region 7a and the lower non-adhesive region 7b is set to be substantially the same as the width necessary for mounting the functional parts such as the handle 12 and the lock locks 10a and 10b, The rigidity of the door 14 can be sufficiently secured while suppressing the warpage and effectively suppressing the locking failure. In addition, the door portion 22 can be adapted to any design door. Of course, it can respond also to the door without the window part 22. FIG.
When the door guard 11 is used, the door 14 is pulled indoors by the door guard 11, but the door 14 is provided with a wooden block body 13 inside the door at the position where the door guard 11 is attached, and both sides of the block body 13 are arranged on the panel 1a. , 1b, the door is not loose.

As shown in FIG. 7, the lower non-bonding region 7 b can be spread upward to the bottom of the block body 13 at the position where the door guard 11 is attached. By doing in this way, the improvement of the effect which prevents the curvature of a door door tip part can be anticipated.
FIG. 8 shows an adhesion state of the outdoor panel 1 a when only one lock 10 is provided above the handle 12. In this case, the lower adhesive region 7b extends from the lower edge of the panel 1a to just below the mounting position of the handle 12. This door 14 can also suppress warping of the door tip portion as in the previous embodiment.

  9 and 10 show another embodiment of the entrance door. In this door 14, the widths of the window portion 22 and the opening portion 27 are significantly larger than those of the previous embodiment. The outdoor panel 1a is provided with an upper non-adhesive region 7a and a lower non-adhesive region 7b as in the previous embodiment. In this door 14, since the opening part 27 is widely provided in the panel 1a of the outdoor side, and the area which receives solar radiation is small, the curvature of a door tip part becomes still smaller than the thing of previous embodiment.

  As described above, the door 14 can reliably reduce the warp generated at the door tip when heated by being exposed to solar radiation. As a result, when using an electronic lock (as opposed to manually locking the door by pulling the door manually), the door may be warped and the dead bolt may come out of the lock receiving hole even a little. Although it cannot be locked normally, this can be effectively solved. The inconvenience of locking due to the warp of the door is generally dealt with by enlarging the hole of the lock receiver 19 or shifting the position of the lock receiver 19 to the outdoor side. This solves the problem of locking. Moreover, the door 14 can be manufactured in the same manner as a normal flush door by simply applying no adhesive to the upper non-adhesive region 7a and the lower non-adhesive region 7b of the outdoor panel 1a. It is excellent in that the warpage of the door tip can be reduced without increasing any of the above. In other words, in practice, it is only necessary to set and input the application area to a fully automatic machine that applies adhesive to the panel, so it can be carried out very easily without changing the conventional procedure, and labor and cost are reduced. The inconvenience of locking can be eliminated without increasing.

  The present invention is not limited to the embodiments described above. The upper non-adhesion region 7a and the lower non-adhesion region 7b can also be provided on the indoor panel 1b. The size of the upper non-bonding region 7a and the lower non-bonding region 7b can be changed as appropriate. The materials of the panels 1a, 1b, the flanges 3, 4, 5, 6, the core material 2, and the edge material 8 are arbitrary. The auxiliary lock is not limited to the arm type, and may be one using a chain. The lock lock may not be an electronic lock and may be integrated with the handle.
