  Further, in this case, a spacer member is attached to the back plate, and the back plate is attached to the attachment location via the spacer member by coupling the spacer member to the attachment location at a position away from the opening. It may be attached to.

  According to this, since the total dimension of the thickness dimension of the building material for doors provided with the opening and the thickness dimension of the spacer member can be secured, the blades of the door hinges are thick plates. However, a sufficient dimension for fitting the blade plate into the opening can be obtained, and the blade plate can be directly coupled to the back plate.

  And the thickness dimension of the slats is the same or substantially the same as the total dimension of the thickness dimension of the door building material and the spacer member, so that the door is rotated around the door hinge. It can be made freely.

  In addition, it is preferable that the number of spacer members coupled to the attachment location is two at positions away from the opening, and these spacer members are attached to both ends in the length direction of the back plate.

According to this, the total dimension of the thickness dimension of the door building material provided with the opening and the thickness dimension of the spacer member can be more reliably ensured. The length direction of the back plate is a direction perpendicular to or substantially perpendicular to the positioning direction of the back plate by the bent portion, and the size of the exposed portion of the back plate exposed from between the two spacer members is It is preferable that the dimension is the same as or substantially the same as the dimension of the opening in a direction perpendicular to or substantially perpendicular to the positioning direction.

  According to this, the back plate can be easily positioned by the two spacer members and the opening in the direction perpendicular to or substantially perpendicular to the back plate positioning direction by the bent portion.

  Further, as described above, the spacer member is attached to the back plate, and the spacer member is attached to the attachment portion at a position away from the opening, whereby the back plate is attached to the door building material via the spacer member. When attaching to a location, it is preferable that the spacer member has a protruding portion that protrudes from an end surface opposite to the end surface of the back plate that contacts the bent portion.

  According to this, the operator can clearly recognize the end surface of the back plate to be brought into contact with the bent portion by the protruding portion of the spacer member out of both end surfaces of the back plate, and performs the positioning operation of the back plate. It will be easier.

  In the present invention described above, the door building material may be a door outer surface forming member that forms the outer surface of at least a part of the door that is rotatable around a door hinge, or may be opened and closed by the door. It may be a component member of a door frame for forming the opening to be formed inside.

  The door may be a front door or an indoor door, and the door hinge positioning structure of the door hinge according to the present invention can be applied to any door.

It is formed by cutting into dimensions. For this reason, the skeleton 11 includes a web 15 whose width direction is the thickness direction of the door 1 and a pair of flanges 16 and 17 extending in the same direction from both ends of the web 15 in the width direction (see also FIG. 4). ).

  Further, as shown in FIG. 3, a box portion 18 is provided inside the door 1, and a latch operated by the door knob 19 and the locking device 20 shown in FIG. Bolt and dead bolt operating mechanisms are housed.

  The indoor-side and outdoor-side surfaces of the door 1 are formed by the indoor-side surface material 21 and the outdoor-side surface material 22 shown in FIG. 3 each having a plate-like shape. It couple | bonds with the flanges 16 and 17 of 10-14 by welding, an adhesive material, etc.

  For this reason, the strength frames 10 to 14 and the surface materials 21 and 22 of the door 1, the left and right vertical frames 5 and 6, the upper frame 7 and the hull 8 of the door frame 3 are door building materials, The first strength frames 10 to 14 and the surface materials 21 and 22 are also door outer surface forming members forming at least a part of the outer surface of the door 1, and the web 15 of the longitudinal strength bone 11 is a door. 1 is formed on the side of the hinge 4 side of 1. Further, the flange 17 of the longitudinal force bone 11 is a bent portion of the longitudinal force bone 11 that is bent at a right angle or a substantially right angle with respect to the web 15.

  2 is a cross-sectional view taken along line S2-S2 of FIG. Of the blades 4A on the door 1 side of the hinge 4 shown in FIG. 1 and the blades 4B on the door frame 3 side, as shown in FIG. 2, the blades 4A on the door 1 side are doors. Among the pair of longitudinal strength bones 10 and 11 that are the left and right structural members 1, they are attached to the inside of the web 15 of the longitudinal strength bone 11 that is the structural material on the hinge 4 side and disposed inside the door 1. The blade 4 </ b> B on the door frame 3 side, which is coupled to the back plate 30, is attached to the inside of the vertical frame 6 that is a suspension source component on the side of the door frame 3 that suspends the door 1. It is coupled to the arranged back plate 31.

  In this embodiment, the back plate 30 arranged inside the door 1 is attached to the web 15 of the longitudinal force bone 11 via a spacer member 33 described later. In this embodiment, the web 15 is an attachment location where the back plate 30 is attached via the spacer member 33. The flange 17 is bent at a right angle or a substantially right angle with respect to the attachment location to form a bent portion.

  As shown in FIG. 3, an opening 32 is formed in the web 15 of the longitudinal force bone 11, and this opening 32, which communicates the inside and outside of the door 1, has three upper and lower hinges 4. Three are provided according to the arrangement position. 4 is a partially enlarged view of FIG. 3, and FIG. 5 is a sectional view taken along line S4-S4 of FIG. Further, FIG. 7 shows an opening 32 excluding the back plate 30 and the like. As can be seen from FIGS. 4, 5, and 7, each of the openings 32 is formed from the indoor flange 16 to the door 1 among the pair of flanges 16 and 17 of the longitudinal force bone 11 formed of the channel material. The web 15 is cut to the outdoor flange 17 from a position slightly apart in the thickness direction, and this cutting operation also cuts the thickness of the outdoor flange 17 and the outdoor surface material 22. At the same time, the outdoor flange 17 and the outdoor surface material 22 are cut inwardly of the door 1.

  Therefore, as shown in FIG. 5, the opening 32 has an L-shaped cross-sectional shape having a long length at the web 15 and a short length at the flange 17.

  FIG. 6 shows the back plate 30 disposed inside the longitudinal force bone 11 of the door 1 described in FIG. The back plate 30, which is thicker than the longitudinal bone 11, has a rectangular shape in which the vertical direction of the door 1 is the length direction of the long side, and 2 on the surface of both end portions in the length direction. The spacer members 33 are attached by welding or the like, and this attachment is performed on the end surfaces 30A and 30B on both sides in the width direction of the back plate 30 (the thickness direction of the door 1) perpendicular to the length direction of the back plate 30. Among these, the position of one end face 30 </ b> A and the position of the end face 33 </ b> A on the same side as the end face 30 </ b> A in each spacer member 33 are made to coincide in the width direction of the back plate 30. Since the dimension in the width direction of the back plate 30 in each spacer member 33 is larger than the width dimension of the back plate 30, each spacer member 33 is opposite to the end face 30 </ b> A of the back plate 30. It has a protruding portion 33B protruding from the side end face 30B.

  As described above, attaching the two spacer members 33 to the surfaces of both end portions in the length direction of the back plate 30 by welding or the like means that the back plate 30 is arranged inside the longitudinal force bone 11 that is a constituent member of the door 1. Has been done before. For this reason, the back plate assembly 40 including the back plate 30 and the two spacer members 33 is manufactured in advance.

  In the back plate assembly 40 shown in FIG. 6, the inner dimension L1 between the two spacer members 33 in the length direction of the back plate 30 is the length of the back plate 30 shown in FIG. It is the same as or substantially the same as the dimension L2 of the opening 32 in the direction, specifically, the dimension L2 is the same as or slightly larger than the dimension L2. Further, as shown in FIG. 5, the dimension (W1 + W2) obtained by adding the width dimension W2 of the back plate 30 to the total thickness dimension W1 of the outdoor surface material 22 and the flange 17 of the longitudinal force bone 11 described above is The same as or substantially the same as the dimension W3 of the opening 32 in the width direction of the back plate 30. Further, the dimension W4 of the spacer member 33 in the width direction of the back plate 30 is larger than the dimension (W3-W1) obtained by subtracting the total thickness dimension W1 from the dimension W3. The dimension W4 is smaller than the inner dimension W5 between the pair of flanges 16 and 17 of the longitudinal force bone 11 in the width direction of the back plate 30. For this reason, the back plate assembly 40 can be dropped from above between the pair of flanges 16 and 17.

  Furthermore, the thickness dimension T1 of the blade 4A on the door 1 side of the hinge 4 described above is the thickness dimension of the web 15 of the longitudinal bone 11 which is the door building material and also serves as the outer surface forming member of the door 1. It is the same or substantially the same as the total dimension T2 with the thickness dimension of the spacer member 33. In this embodiment, the thickness dimension T1 is slightly larger than the total dimension T2.

  As shown in FIG. 2, since the blade 4A on the door 1 side of the hinge 4 is coupled to the back plate 30 by screws 41, as shown in FIG. A screw hole 42 into which the screw 41 is screwed is formed at a position within the inner dimension L1 exposed between the spacer members 33.

  The back plate assembly 40 is arranged inside the longitudinal bone 11 of the door 1 during the door 1 manufacturing process. This placement operation is performed by placing the above-mentioned outdoor surface material 22 on the work table, in other words, as shown in FIG. 3, a bent portion bent with respect to the web 15 of the longitudinal force bone 11. This is performed after the door 1 is placed in a horizontal position in a flat state on the work table by lowering the flange 17 that is formed. After the door 1 is placed in such a horizontal position, the back plate assembly 40 is placed on the inside of the longitudinal bone 11 in the width direction of the back plate 30 (in FIG. 3, the vertical direction and the thickness of the door 1). Direction) and attaching to the web 15 of the longitudinal force bone 11 is performed. This positioning attachment work is performed by forming two spacer members 33 on the web 15 as shown in FIG. The back plate 30 is placed on both sides of the opening 32, in other words, the positions of the spacer members 33 are moved away from the opening 32, and the back plate assembly 40 is dropped from above. 5A and the end surface 33A of the spacer member 33 that coincides with the position of the end surface 30A in the width direction of the back plate 30 are brought into contact with the flange 17 of the longitudinal bone 11 as shown in FIG. By touching Performed by the abutment, the back plate 30 is positioned in the width direction of the back plate 30 is a thickness direction of the door 1.

  Next, an operation of joining the two spacer members 33 brought into contact with the web 15 of the longitudinal force bone 11 to the web 15 and the flange 17 by welding or the like is performed, and thereby the back plate 30 is formed by two spacer members. The web 15 is attached to the web 15 of the longitudinal force bone 11 via 33, and this web 15 becomes an attachment location of the back plate 30. Further, when the back plate 30 is attached to the web 15 of the longitudinal force bone 11 via the two spacer members 33 in this way, the respective spacer members 33 are cross-sectioned into the web 15 and the flange 17 of the longitudinal force bone 11 in the section L. At the position deviating from the opening 32 formed in the character, it is coupled to the mounting location, and further, a part of the back plate 30 is exposed from the opening 32, and this part is described above. Screw holes 42 are formed.

  Thereafter, as shown in FIG. 5, an operation of fitting the blade 4 </ b> A on the door 1 side of the hinge 4 into the opening 32 from the outside of the door 1 is performed, and the blade fitted into the opening 32. The plate 4 </ b> A is coupled to the back plate 30 by screws 41 that are screwed into screw holes 42 formed in the back plate 30.

  As described above, the back plate 30 when the blades 4 </ b> A on the door 1 side are coupled with the screws 41 is in contact with the flange 17 in the width direction of the back plate 30 as described above. Since the positioning of the back plate 30 in the width direction of the back plate 30 is accurately set by this positioning, the positioning of the door device for the entrance shown in FIG. After the construction is completed, when the door 1 is rotated about the hinge 4 with the door knob 19, the door 1 can be opened and closed as predetermined with respect to the opening 2 serving as an entrance.

  As described above, in this embodiment, the work for attaching the back plate 30 to the web 15 of the longitudinal force bone 11 which is a door building material and is an outer surface forming member of the door 1 is performed on the web 15. The back plate 30 is positioned by bringing the end surface 30A of the back plate 30 into contact with the bent flange 17, and the flange 17 is a door for forming at least a part of the outer surface of the door 1. Since it is a bent portion that is bent at a right angle or a substantially right angle with respect to the web 15 that is the back plate attachment portion of the longitudinal force bone 11 that is the outer surface forming member, the positioning operation of the back plate 30 is performed by the vertical force. This can be performed by effectively using the bent portion that the bone 11 originally has. For this reason, the work for positioning the back plate 30 on the longitudinal force bone 11 and attaching it to the attachment location of the longitudinal force bone 11 is performed. Easy and short Performed between, it is possible to improve the efficiency of this process.

  Further, in this embodiment, when the back plate 30 is positioned on the longitudinal force bone 11 by bringing the end surface 30A of the back plate 30 into contact with the flange 17 which is a bent portion of the longitudinal force bone 11, the door 1 and the longitudinal plate 30 are arranged. The strength bone 11 is in a posture with the flange 17 on the lower side, and the positioning of the back plate 30 is performed by positioning the back plate 30 with the end surface 30A facing downward of the back plate contacting the flange 17.

It is a direction that makes a right angle. As described above, the back plate assembly 40 has two spacer members 33 attached to both ends in the length direction of the back plate 30, and the inner dimension L 1 between these spacer members 33. In other words, the dimension L1 of the exposed portion of the back plate 30 exposed between the two spacer members 33 is the same as the dimension L2 of the opening 32 in the length direction of the back plate 30 or this dimension L2. Is a little bigger.

  Therefore, the positioning of the back plate 30 in the direction perpendicular to or substantially perpendicular to the positioning direction of the back plate 30 by the flange 17 can be easily performed by the opening 32 and the two spacer members 33.

  Further, as described above, the spacer member 33 is provided with the protruding portion 33B that protrudes from the end surface 30B of the two end surfaces 30A and 30B of the back plate 30, and the end surface 30B is provided on the back plate 30. Since the end face is opposite to the end face 30A that is brought into contact with the flange 17 for positioning, the operator makes contact with the flange 17 out of both the end faces 30A and 30B of the back board 30 and the back board 30. The end surface 30A for positioning can be clearly recognized by the protruding portion 33B of the spacer member 33, whereby the positioning operation of the back plate 30 can be performed more easily.
