[Modes for carrying out the invention]

[0008] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. The door body 1 of this embodiment is an entrance door consisting of a hinged door that is housed in a frame provided in an opening of a building structure (not shown) and opens toward the exterior side X1 around a pivot axis (not shown) on the hinge side.

[0009] As shown in Figures 1 to 7, the door body 1 has a door body 2 in which surface materials 2a and 2b made of steel plates are attached to both the exterior side X1 and the interior side X2 of a rectangular core material 3. An exterior handle 21a is attached to the door edge side of the surface material 2a on the exterior side X1, and an interior handle 21b and a door guard 23 are attached to the door edge side of the surface material 2b on the interior side X2. A door closer 22 is attached to the upper part of the hinge side of the door body 2. A locking device 4 is attached to the door body 2 from the visible surface on the door edge side. The locking device 4 has locking devices 4a and 4b consisting of cylinder locks arranged above and below the exterior handle 21a and the interior handle 21b, and a locking device 4c consisting of a latch lock arranged between the locking devices 4a and 4b and operated by the operation of the exterior handle 21a and the interior handle 21b.

[0010] Here, the directions in door body 1 and door body 2 are defined as follows: In the diagram, arrow X1 indicates the exterior side, and X2 indicates the interior side. Y1 indicates the upper side of door body 1 and door body 2, and Y2 indicates the lower side of door body 1 and door body 2. In door body 1 and door body 2, the direction connecting the exterior side X1 and the interior side X2 is called the depth direction. In door body 1 and door body 2, the surface arranged along the depth direction is called the depth surface. In Figure 4, the right side is the leading edge side of door body 1 and door body 2, and the left side is the hinge side of door body 1 and door body 2.

[0011] The core material 3 is constructed by framing an upper core material 31, a lower core material 32, and a pair of left and right vertical core materials 33 and 34, each made of metal profiles, in a rectangular shape to surround the four sides of the door body 2. As shown in Figure 7, the visible surface 33a of the vertical core material 33, which is positioned on the door edge side of the door body 2, has a vertically elongated rectangular housing hole 331 for housing the lock device 4 inside the door body 2. Figure 7 shows the mounting location of the lock device 4a, which is positioned at the very top, but similar housing holes 331 are also formed on the visible surface 33a of the vertical core material 33 for the mounting locations of the other lock devices 4b and 4c.

[0012] As shown in Figure 7, the locking device 4 has a lock case 41 that constitutes a box-shaped lock body and a flange portion 42. The flange portion 42 is made of a vertically elongated rectangular metal plate that constitutes the exposed surface on the door edge side of the door body 1 in the locking device 4. The flange portion 42 is formed to extend outwards from the top and bottom of the lock case 41 along the visible surface 33a of the vertical core material 33. The locking device 4 is attached to the visible surface 33a of the vertical core material 33 by screws 40, 40 inserted through through holes 421, 421 in the flange portion 42 at both the top and bottom ends of the flange portion 42. Screw holes 332 into which the screws 40 are screwed are formed above and below the housing hole 331 in the visible surface 33a.

[0013] As shown in Figures 6 and 7, the door edge material 5 is attached to the vertical core material 33 on the door edge side via an edge fixing component 6. The door edge material 5 is made of a metal profile and covers the entire visible surface 33a of the vertical core material 33 along the extension direction of the vertical core material 33. The door edge material 5 is provided along the entire length in the height direction of the door body 2.

[0014] The door edge material 5 has a flat edge material body 51 positioned along the visible surface 33a of the vertical core material 33. The edge material body 51 has a vertically elongated rectangular opening 511 formed at a position corresponding to the housing hole 331 of the vertical core material 33. The opening 511 has a larger opening area than the housing hole 331 of the vertical core material 33 so that the flange portion 42 of the locking device 4 can be accommodated inside.

[0015] The edge material body 51 is integrally provided with a pair of mounting pieces 52, 52 for attaching to the edge fixing component 6 and a support leg 53. The pair of mounting pieces 52, 52 and the support leg 53 project from the back surface 51a of the edge material body 51 toward the prospective surface 33a of the vertical core material 33.

[0016] The pair of mounting pieces 52, 52 extend in parallel through both sides of the opening 511 over the entire length in the extending direction of the door tip edge material 5. At the tips of the pair of mounting pieces 52, 52, claw portions 521, 521 for locking to the edge fixing component 6 are formed so as to face each other with the opening 511 interposed therebetween.

[0017] The support leg 53 constitutes the leg portion of the door tip edge material 5 that abuts against the prospective surface 33a of the vertical core material 33. The protruding height of the support leg 53 from the back surface 51a of the edge material body 51 is equivalent to the protruding height of the pair of mounting pieces 52, 52. The support leg 53 extends in parallel with the pair of mounting pieces 52, 52 over the entire length in the extending direction of the door tip edge material 5, but is partially interrupted at the opening 511. The support leg 53 maintains the edge material body 51 at a certain interval from the prospective surface 33a by abutting against the prospective surface 33a of the vertical core material 33.

[0018] Next, the edge fixing component 6 will be described. The edge fixing component 6 is an integrally molded product integrally formed of a resin material, and as shown in FIG. 5, two are provided corresponding to each locking device 4a to 4c. Specifically, the edge fixing component 6 is attached to the prospective surface 33a so as to be disposed between the upper and lower end portions of the flange portion 42 of each locking device 4a to 4c and the prospective surface 33a of the vertical core material 33. The edge fixing components 6 corresponding to each locking device 4a to 4c have the same structure.

[0019] The structure of the edge fixing component 6 will be described with reference to FIGS. 8 and 9. The edge fixing component 6 includes a fixing component body 61, a first fixing portion 62 for attaching and fixing the edge fixing component 6 to the prospective surface 33a of the vertical core material 33, and a second fixing portion 63 for attaching and fixing the door tip edge material 5 to the edge fixing component 6.

[0020] The fixed part body 61 is formed in a rectangular shape that extends in the width direction and the vertical direction of the prospective surface 33a of the vertical core material 33 when viewed from the front. The width direction of the prospective surface 33a of the vertical core material 33 is the indoor-outdoor direction. The lateral width of the fixed part body 61 along the width direction of the prospective surface 33a is smaller than the distance between the pair of mounting pieces 52, 52 of the door edge material 5. An insertion hole 611 for inserting a screw 40 for fixing the lock device 4 to the prospective surface 33a is formed in the central part of the fixed part body 61.

[0021] The fixed part body 61 is sandwiched between the prospective surface 33a of the vertical core material 33 and the flange part 42 of the lock device 4 attached to the prospective surface 33a. Thereby, the fixed part body 61 functions as a spacer for adjusting the distance between the prospective surface 33a and the flange part 42. That is, when the flange part 42 is brought into contact with the surface 61a of the fixed part body 61 during the attachment of the lock device 4, the flange part 42 is attached away from the prospective surface 33a of the vertical core material 33 by the thickness of the fixed part body 61. The attachment height of the flange part 42 from the prospective surface 33a is adjusted by the thickness of the fixed part body 61. Specifically, the position of the surface 42a of the flange part 42 is adjusted to be about 0.5 mm higher than the position of the surface 51b of the edge material body 51 of the door edge material 5. Thereby, it is possible to prevent the user's hand or the like from directly touching the processed edge of the periphery of the opening 511 formed in the edge material body 51.

[0022] The first fixing part 62 is configured to have a pair of mounting claw parts 621, 621 that protrude from the back surface 61b of the fixed part body 61 toward the prospective surface 33a of the vertical core material 33. As shown in FIG. 7, the pair of mounting claw parts 621, 621 are inserted into mounting holes 333, 333 formed so as to sandwich the screw hole 332 of the vertical core material 33 from both sides in the width direction. Thereby, the pair of mounting claw parts 621, 621 attach the edge fixing part 6 to the prospective surface 33a of the vertical core material 33. The pair of mounting claw parts 621, 621 are arranged on both sides in the width direction of the fixed part body 61 with the insertion hole 611 at the center of the fixed part body 61 interposed therebetween. The width direction of the fixed part body 61 is the indoor-outdoor direction.

[0023] The pair of mounting claws 621, 621 and the insertion hole 611 are arranged side by side on the same straight line L along the width direction of the fixing part body 61. The pair of mounting claws 621, 621 and the insertion hole 611 on the same straight line L are arranged at equal intervals. Since the edge fixing part 6 does not have a distinction between L (left) and R (right), it can be used without worrying about left or right.

[0024] As shown in Figure 9, the mounting claw portion 621 has a pointed tip portion 621a. Near the base of the mounting portion 621, locking claws 621b, 621b protrude in opposite directions in the width direction. In the width direction center of the mounting claw portion 621 sandwiched between the locking claws 621b, 621b, a weight-reducing portion 621c is formed along the length direction of the mounting claw portion 621, and the mounting claw portion 621 is formed in a roughly U-shape with a pointed tip portion 621a. As a result, when the mounting claw portion 621 is inserted into the mounting hole 333 of the vertical core material 33, the portions of the locking claws 621b, 621b easily deform elastically toward the weight-reducing portion 621c to pass through the mounting hole 333, and then elastically return to their original shape, thereby locking onto the back surface 33b of the vertical core material 33.

[0025] The second fixing part 63 has an engaging claw portion 631 that engages with a pair of mounting pieces 52 of the door edge material 5. More specifically, the edge fixing part 6 has a pair of left and right engaging claw portions 631, 631 that are arranged at both ends in the width direction of the fixing part body 61 and engage with a pair of mounting pieces 52, 52 of the door edge material 5. The left and right pair of engaging claw portions 631, 631 are arranged on the upper end side and the lower end side of the fixing part body 61 when the edge fixing part 6 is viewed from the front, as shown in Figure 8. The left and right pair of engaging claw portions 631, 631 are arranged in pairs on the upper end side and the lower end side of the fixing part body 61 along the extending direction of the vertical core material 33. Therefore, as shown in Figure 8, the edge fixing part 6 has four engaging claw portions 631 that protrude in the left and right width directions of the fixing part body 61.

[0026] The four engaging claws 631 are arranged so that when the fixing part body 61 is sandwiched between the visible surface 33a of the vertical core material 33 and the flange portion 42 of the locking device 4, two claws protrude outwards on each side in the width direction of the flange portion 42. When the edge fixing part 6 is viewed from the front, the four engaging claws 631 are located at the four corners of the edge fixing part 6 and are arranged symmetrically above and below a straight line L. Since the edge fixing part 6 has no distinction between top and bottom, and is symmetrical left and right, it can be used without worrying about its orientation. However, the number of engaging claws 631 provided on the edge fixing part 6 is not limited to four; two engaging claws 631, 631 may be provided on both sides in the width direction of the fixing part body 61.

[0027] Next, we will explain the installation process for attaching the locking device 4 and the door edge material 5 to the vertical core material 33 using this edge fixing component 6.

[0028] First, a pair of mounting claws 621, 621 of the edge fixing component 6 are inserted into a pair of mounting holes 333, 333 formed in the visible surface 33a of the vertical core material 33 on the door-side of the door body 2. The locking claws 621b, 621b of the mounting claws 621 are inserted into the mounting holes 333 while elastically bending and deforming, and then elastically return to their original position after passing through the mounting holes 333. As a result, the pair of mounting claws 621, 621 are locked to the back surface 33b of the vertical core material 33, as shown in Figure 9, and the edge fixing component 6 is fixed to the vertical core material 33. The fixing component body 61 of the edge fixing component 6 is positioned on the visible surface 33a of the vertical core material 33. The edge fixing component 6 is similarly attached to the top and bottom of each of the three housing holes 331 provided in the vertical core material 33. Since the edge fixing component 6 does not have a left / right distinction, the installation work can be easily performed.

[0029] Next, the door edge material 5 is attached across the six edge fixing parts 6 attached to the vertical core material 33. Specifically, the door edge material 5 is positioned so that the two upper and lower edge fixing parts 6, 6 and the accommodating hole 331 between them face each opening 511 of the door edge material 5. In this state, as shown in Figure 9, the door edge material 5 is attached by sandwiching each edge fixing part 6 with a pair of mounting pieces 52, 52.

[0030] Each edge fixing component 6 engages with one mounting piece 52 by two upper and lower engaging claws 631, 631. Therefore, each edge fixing component 6 engages with a pair of mounting pieces 52, 52 by four engaging claws 631, one above, one below, one on the left and one on the right. As a result, the edge fixing component 6 can firmly fix and hold the door edge material 5. Since there is no need to use separate screws to fasten the door edge material 5 to the visible surface 33a of the vertical core material 33, the appearance of the surface 51b of the edge material body 51 of the door edge material 5 can be made neater, as shown in Figures 1, 2 and 5, and the design of the door body 1 is improved.

[0031] Inside each opening 511 of the door edge material 5 attached to the vertical core material 33, there is a housing hole 331 of the vertical core material 33 and, above and below it, an edge fixing part 6, 6. Subsequently, as shown in Figure 7, the lock case 41 is housed in the housing hole 331 of the vertical core material 33 through the opening 511 of the door edge material 5, and the lock device 4 is attached to the vertical core material 33.

[0032] Specifically, the flange portion 42 of the locking device 4 abuts against the surface 61a of the fixing part bodies 61, 61 of the upper and lower edge fixing parts 6, 6 of the housing hole 331. A pair of screws 40, 40 pass through the through holes 421, 421 of the flange portion 42 and the insertion holes 611, 611 of the upper and lower edge fixing parts 6, 6, and are screwed into the screw holes 332, 332 of the vertical core material 33. In this way, the flange portion 42 is fixed to the visible surface 33a of the vertical core material 33. The height position of the flange portion 42 from the visible surface 33a of the vertical core material 33 is adjusted by the thickness of the fixing part body 61 so that it is about 0.5 mm higher than the surface 51b of the edge material body 51, as shown in Figure 6.

[0033] According to this embodiment, the following effects are achieved. Specifically, the door body 2 has a vertical core material 33 on the door edge side, a door edge material 5 is positioned on the visible surface 33a of the vertical core material 33 of the door body 2, an edge fixing part 6 fixes the door edge material 5 to the visible surface 33a, and a locking device 4 is attached to the visible surface 33a. The door edge material 5 has a pair of mounting pieces 52, 52 that are attached to the edge fixing part 6 so as to sandwich the edge fixing part 6 between them, and the locking device 4 has a lock case 41 housed inside the door body 2, and The door body 1 has a flange portion 42 extending vertically along the recessed surface 33a of the lock case 41, and the edge fixing part 6 has a fixing part body 61 positioned between the recessed surface 33a and the flange portion 42 to adjust the mounting height of the flange portion 42 from the recessed surface 33a, a first fixing part 62 that fixes the edge fixing part 6 to the recessed surface 33a, and a second fixing part 63 that engages with a pair of mounting pieces 52, 52 of the door edge material 5 to fix the door edge material 5.

[0034] According to this, the edge fixing part 6, which is a height adjustment part for adjusting the mounting height of the flange portion 42, is attached to the vertical core material 33, so there is no need to provide an engagement part for attaching the height adjustment part to the door edge material 5. The door edge material 5 only needs to have a pair of mounting pieces 52, 52 for attaching to the vertical core material 33, so the structure of the door edge material 5 can be simplified. The door edge material 5 can be installed by only working on the surface 33a of the vertical core material 33, which consists of installing the edge fixing part 6 to the surface 33a of the vertical core material 33 and installing the door edge material 5 to the surface 33a with the edge fixing part 6 installed, thus improving work efficiency.

[0035] In this embodiment, the edge fixing part 6 has a screw insertion hole 611 for fixing the flange portion 42 to the vertical core material 33, and the first fixing part 62 has a pair of mounting claws 621, 621 arranged on both sides in the width direction with respect to the insertion hole 611, and the insertion hole 611 and the pair of mounting claws 621, 621 are arranged in a straight line in the width direction of the edge fixing part 6.

[0036] According to this, since there is no distinction between L (left) and R (right) in the edge fixing part 6, it offers excellent workability when attaching the edge fixing part 6 to the vertical core material 33.

[0037] In this embodiment, the edge fixing component 6 has a pair of engaging claws 631, 631 positioned at both ends in the width direction of the fixing component body 61, on the upper end side and the lower end side of the fixing component body 61, respectively, along the extending direction of the vertical core material 33.

[0038] According to this, the edge fixing component 6 can firmly fix and hold the door edge material 5, eliminating the need to use separate screws to fasten the door edge material 5 to the visible surface 33a of the vertical core material 33, thereby improving the aesthetic appearance of the door body 1.
