  Hereinafter, the present invention will be described in more detail with reference to the example of the drawings. In FIG. 1 to FIG. 5, A is a modified door in which a new door 2 is installed on an existing door frame 1 that has been removed by removing an existing door. The refurbished door A has a handle 34 fixed with a pair of upper and lower lock cases 31 projecting inwardly on the indoor side of the new door 2 as a receiving seat, and the outdoor side of the new door 2 directly on the surface of the door. The push-pull lock 3 is installed by attaching the handle 34 and the pair of upper and lower latches for receiving each latch 32 from the lock case 31 on the indoor side expected surface of the door-holding side vertical frame 11 in the existing door frame 1. The receiving holes 41 and 51 are arranged, and the new door 2 is locked and unlocked by the push-pull lock 3.

  That is, the refurbished door A remains, for example, by removing an existing door of a so-called KJ door, that is, a press door formed by press-molding a steel plate and suspended and supported on an existing door frame, and a hinge that supports the suspended door. The existing door frame 1 is refurbished by, for example, suspending and supporting the new door 2 by a double-sided flash door filled with a heat insulating and soundproofing material using a hinge 12 for earthquake resistance. At this time, the new door 2 has a door thickness of 40 mm so that it fits into the expected width 41 mm of the outdoor-side expected surface of the existing door frame 1. Has a stepped portion having an L-shaped cross section on the outer periphery of the indoor-side finding surface, and an airtight material receiving frame having a U-shaped cross section is disposed on the stepped portion. It is assumed that the material 21 is mounted and airtightness is secured with the existing door frame 1 by contacting the door 21 with the door step portion of the existing door frame 1.

  At this time, the lock case 31 is made of a stainless box and forms a pair of upper and lower front rectangles. A lock mechanism for projecting and retracting the latch 32 by the operation of the handle 34 is separately incorporated, and a pair of upper and lower parts are separated. For example, the screws at the corners of the four corners are screwed into the center of the new door 2 so as to be fixed to the above-mentioned indoor-side finding surface, and fixed to the indoor-side finding surface. The lock cases 31 are respectively used as upper and lower seats, the upper and lower pedestals of the indoor handle 34 are brought into contact with each other, and the handles 34 are fixed to the lock case 31 with screws from the respective pedestals. The outdoor handle 34 has its upper and lower pedestals directly in contact with the outdoor-side finding surface without using the above-mentioned seat, and the handle 34 is directly attached to the finding surface with screws from each pedestal. Poppy and is fixed. At this time, the connecting levers of the upper and lower handles 34 are connected to a locking mechanism in the lock case 31 through a through hole provided in the box of the lock case 31 on the indoor side, and the surface plate of the new door 2 on the outdoor side. Similarly, the connecting bar is connected to the locking mechanism in the lock case 31 so as to cross the new door 2 through the through-hole formed in the door. The locking mechanism is actuated via the bar to project and retract the latch 32.

  In this example, the pair of upper and lower lock cases 31 are covered in series in this example. For example, an appropriate metal cover 33 such as stainless steel or a decorative steel plate is provided to expose the lock case 31. Therefore, in the present example, the fixing of the handle 34 using the lock case 31 as a pedestal is performed through the cover 33.

  At this time, the pair of upper and lower lock cases 31 of this example is disposed close to the end of the indoor-side finding surface of the new door 2, while the pair of upper and lower latch receiving holes 41 are arranged vertically on the door side. Arranged in a pair of latch receivers 4 above and below each of the latch receiving holes 41 covering the machining holes formed in the field by performing partial notch processing on the indoor side expected surface of the frame 11 and removing the mortar on the back surface Thus, the latch 32 is protruded and retracted by the operation of the handle 34 in this example with respect to the pair of upper and lower latch receivers 4 of the existing door frame 1. 42 is a thumb-turn latch receiving hole disposed in addition to the latch receiving hole 41 from the upper lock case 31.

  That is, the above-mentioned pair of upper and lower lock cases 31 installed on the indoor-side surface of the new door 2 has a latch 32 that can be freely projected and retracted, and a latch for the door-holding side vertical frame 11 of the existing door frame 1. In order to enter the receiving hole 41 and be surely locked to the receiving hole 41, the end of the new door can be locked on the indoor side, that is, on the end located on the door-holding side vertical frame 11 side. In the lock case 31 of this example, which is arranged as close as possible to a few millimeters, particularly 2 to 3 mm, and is provided with the cover 33, the cover 3 is the above-mentioned of the new door 2. The airtight material 21 is arranged so as to be close to several mm, particularly 2 to 3 mm, from the step where the airtight material 21 is installed.

  On the other hand, the latch receiver 4 has, for example, two upper and lower cutouts in the middle in the longitudinal direction aligned with the position of the latch 32 of the lock case 31 on the indoor side of the door-holding side vertical frame 11 of the existing door frame 1. For example, by screwing on the indoor side finding surface of the door-holding side vertical frame 11 so that the edge of the notch hole that has been removed over the two back surface mortars is covered with makeup, The latch receiver 4 is provided with a pair of upper and lower latch receiving holes 41. In this example, the upper latch receiver 4 is further provided with a latch receiving hole 42 for the thumb turn.

  Therefore, the new door 2 of the present example has a thickness of about 5 to 6.5 cm while the outside expected surface of the door-holding side vertical frame 11 of the existing door frame 1 has a thickness of 40 mm in accordance with the 41 mm. It is possible to install a push-pull lock 3 on the premise that it is built in a new door and to lock and unlock the push-pull lock 3 between the push-pull lock 3 and the existing door frame 1. The same door opening as that of the renovated door with no narrowing, and its design and usability can be improved.

  FIGS. 6 to 9 show other examples. In this example, the new door 2 in the refurbished door A has the above-mentioned pair of upper and lower lock cases 31 connected to the indoor side finding surface of the new door 2. While the door holding side vertical frame 11 is spaced apart from the end portion, the pair of upper and lower latch receiving holes 51 are attached to the indoor side expected surface of the door holding side vertical frame 11 and fixed thereto. This is an example of arrangement.

  In this example, the lock case 31 is provided with the above-mentioned airtight material 21 of the new door 2 at the end of the indoor-side finding surface of the new door 2, also at the end located on the door-holding side vertical frame 11 side. The position corresponding to the protrusion length of the latch 32 is separated from the stepped portion in the in-plane direction by several cm or less, for example, about 2 cm in this example. Are installed on the indoor side of the new door 2.

  On the other hand, the pair of upper and lower latch receiving holes 51 are arranged in the attachment member 5 in this example, and the attachment member 5 in this example is attached to the door frame side vertical frame 11. The latch 32 is received and locked in accordance with the separation distance from the end of the lock case 31 from the indoor side expected surface, and the projecting width necessary for performing the locking and unlocking is about 2 cm in this example. It has a narrow protrusion width, for example, a metal long member having a length of about 30 cm, such as stainless steel, a thick decorative steel plate of about 1 to 2 mm, etc. The length of the member 5 is the same as that of the cover 33 covering the lock case 31, so that the interior appearance in which the attachment member 5 is installed in the door-holding side vertical frame 11 is made as much as possible. As good, it is not uncomfortable.

  The attachment member 5 is in the form of a box, in the present example, the above-mentioned narrow and long box with a C-shaped cross section with the top and bottom closed, and in the middle of the longitudinal direction, at the latch 32 position of the lock case 31. At the same time, the pair of upper and lower latch receiving holes 51, and in this example, the latch receiving hole 52 for the thumb turn is provided in the same manner as described above. In the hollow portion of the member 5, the upper and lower sides of the latch receiving hole 51 are partitioned inside, and the bottom surface that is in contact with the door-end side vertical frame 11 from the opening of the latch receiving hole 51 is the chamber of the door-end side vertical frame 11. As a reinforcement to reinforce the C-shaped attachment member 5 that is attached and fixed to the inner surface by screwing, there is a latch 32 of the lock case 31 on the attachment member 5 and above. The same metal that accepts and houses the thumb-turn latch at the same time. It is disposed a box 53.

  Therefore, in this example, the new door 2 is similarly provided with a push-pull lock 3 with a thickness of about 4 cm, particularly 40 mm, and between the push-pull lock 3 and the existing door frame 1. The door to be locked and unlocked can be improved in the design and usability of the refurbished door A. The refurbished door A in this example uses the above-mentioned attachment member 5, The projecting width can be made as narrow as necessary to receive the latch 32 and lock it to the door-side vertical frame 11 of the existing door frame 1. By partially installing the door frame 1 at the middle position in the longitudinal direction of the door-holding side vertical frame 11, a narrowed portion corresponding to the protruding width is generated in the door opening, but the additional narrowing is not caused. The installation member 5 is installed and its narrowing is suppressed as much as possible. Furthermore, in the modified door A of this example, the attachment member 5 may be retrofitted to the existing door frame 1 at the site as a factory production member, so the above example for the existing door frame 1 Thus, it is possible to eliminate the on-site processing as described above, simplify the renovation work, and prevent the generation of noise and dust associated with the work.
