The door frame 1 includes two vertical frames 11, 11 positioned on the left and right sides, and an upper frame 12 (kamoi) horizontally mounted between the upper ends of both the vertical frames 11, 11. An opening 13 is formed inside. A plurality of upper and lower hinges 14, 14,... (Two in FIG. 1) are attached to the right vertical frame 11, and the door 2 is supported by the hinges 14, 14,. Yes. The opening 13 is opened and closed by swinging the door 2. A left-side vertical frame 11 is provided with a bottomed box-like latch receiver 9. In the following description, the side of the vertical frame 11 to which the hinges 14, 14,... Are attached is the right side, and the side of the vertical frame 11 on which the other latch receiver 9 is disposed is the left side.

  As shown in FIGS. 1 and 2, the door 2 is a door having a flash panel structure in which decorative plates 29 and 29 made of MDF or the like are integrally joined to the front and back surfaces of a rectangular frame-shaped four-sided ridge (core material). is there. Specifically, the four-way rod is, for example, the outer vertical rods 21 and 21 positioned at the left and right ends of the door 2 and the upper and lower horizontal rail members 22 respectively connected between the upper and lower ends of the outer vertical rods 21 and 21. , 22. Further, the upper and lower horizontal rail members 22 and 22 are connected by two inner vertical rod members 23 and 24 between both outer vertical rod members 21 and 21. These outer vertical bar members 21, 21, upper and lower horizontal beam members 22, 22 and the two inner vertical bar members 23, 24 are all located on the same plane, and a decorative plate 29 is provided on the front surface and the rear surface, respectively. , 29 are integrally joined and fixed.

  The door 2 has a door body 20 in which a notch 25 is formed by notching an intermediate portion in the vertical direction at the left end in a rectangular shape when viewed from the front. The left outer vertical gutter 21 is vertically separated at a position corresponding to the notch 25 (an intermediate position in the vertical direction). The left inner vertical bar 23 is erected along the right side surface of the notch 25. Further, the left outer vertical member 21 and the left inner vertical member 23 are connected by inner horizontal rail members 26 and 26 extending along the upper and lower side surfaces of the notch 25. That is, the notch 25 is partitioned by both inner side crosspieces 26, 26 and the left inner side vertical bar 23. The handle unit 3 is fixedly attached to the notch 25.

  As shown in FIG. 3, the handle unit 3 includes a front plate 4 and a stop guide 5 that are arranged opposite to each other in the left-right direction, and a pair of plate handles 6 that connect the front and rear ends of the front plate 4 and the stop guide 5 and face each other. 6 are arranged in a box shape. The thickness of the handle unit 3 in the front-rear direction is substantially the same as the thickness of the door body 20. Therefore, when the handle unit 3 is attached and fixed to the notch 25, the outer surfaces of the plate handles 6, 6 and the outer surface of the decorative plate 29 in the front-rear direction are flush with each other (FIGS. 2 and 6). In other words, the plate handles 6 and 6 are respectively provided in the same plane as the front-rear surface of the door body 20 (the front-rear direction outer surface of the decorative plate 29). In the present disclosure, “in the same plane” refers to substantially in the same plane. Specifically, it is a concept that includes plate handles 6 and 6 that are slightly protruded or slightly recessed with respect to the front-rear surface of the door body 20. More specifically, for example, it is a concept that includes a plate handle 6, 6 that is recessed in the front-rear direction of the door body 20 with a width corresponding to the thickness of the decorative plate. The same applies to “Same”.

  The front plate 4 extends in the vertical direction, and the height in the vertical direction is set slightly higher than the height in the vertical direction of the notch. The front plate 4 is formed with screw holes 41 and 41 at positions projecting from the upper and lower ends of the notch 25 when the handle unit 3 is attached to the notch 25. The front plate 4 is screwed and fixed to the inner horizontal rail member 26 or the left outer vertical rod member 21 by screws 42, 42 inserted into the screw holes 41, 41. A rectangular guide hole 43 configured to allow a latch engagement portion 81a (see FIG. 3) of a swing latch 8 (described later) to be taken in and out is provided at the middle position in the vertical direction of the front plate 4. It is formed penetrating in the left-right direction.

  The stop guide 5 is a substantially rectangular plate extending in the vertical direction. The left side surface of the stop guide 5 is formed with a recessed portion 51 that is recessed in a substantially curved shape, and constitutes a clue portion for opening and closing the door. The front and rear end portions 51a, 51a on the open end side of the recessed portion 51 are formed slightly longer in the left-right direction so that a locking step portion 64 of the plate handle 6 described later can be locked. The height of the stop guide 5 is slightly lower than the height of the notch 25, and screw holes 52 and 52 are formed through it at positions close to the end in the vertical direction. The stop guide 5 is screwed and fixed to the left inner vertical rod 23 with screws 53 and 53 inserted into the screw holes 52 and 52.

  As shown in FIGS. 4 and 5, a pair of upper and lower hinges 61, 61 project from the left end of the plate handle 6, and the front plate 4 extends in the front-rear direction via the hinges 61, 61. It is pivotally supported at the end so that it can swing. Also, a substantially spherical trapezoidal spring receiver 62 projects from the center portion of the inner surface of the plate handle 6, and a spring spring that urges the plate handles 6 and 6 outward between the spring receivers 62 and 62. 69 (see FIG. 6) is inserted.

  The right end portion of the plate handle 6 is slightly thick, and the front and rear end portions 51a and 51a (open) of the recessed portion 51 of the stop guide 5 are formed outside the thick portion (hereinafter referred to as the thick portion 63). A locking step portion 64 that is locked from the inside is formed at both end portions on the side. As described above, since the locking step 64 and the stop guide 5 are respectively locked, the movement of the two plate handles 6 and 6 swinging outward from the surface of the door body 20 is restricted (FIG. 3). reference). Accordingly, the pair of plate handles 6 and 6 are held in a flat state with the surface of the door body 20 in a state before operation (when not operated), and the other side from the flat state toward the inside of the door body 20 It can be pushed in until it abuts against the plate handle 6, that is, it can swing.

  It is also possible to configure the door body 20 (door 2) by omitting the stop guide 5. Specifically, the position corresponding to the notched portion 25 of the left inner vertical rod member 23 can be realized by recessing on a substantially curved surface in the same manner as the recessed portion 51 of the stop guide 5.

  A box-like key box 7 is integrally projected on the inner surface (right side surface) of the front plate 4. As shown in FIGS. 6 and 7, a swing latch 8 is accommodated in the box-like key box 7 so as to be swingable in the left-right direction. The swing latch 8 is constituted by an inverted L-shaped swing body 81 and a substantially U-shaped fork 82 opened on the right side when viewed in the front-rear direction. The fork 82 and the swing body 81 are arranged side by side in the vertical direction. Although not shown in detail, the upper end portion of the swing body 81 is recessed in a U-shape when viewed from above and a substantially L-shape when viewed in the front-rear direction, so that the lower left portion (intermediate portion) of the fork 82 can be inserted. It is like that. Then, in a state where the intermediate portion of the fork 82 is inserted into the swing body 81, the two are integrally connected using a connecting pin 83. The lower left end of the swing body 81 constitutes a latch engaging portion 81a. The upper and lower open ends of the fork 82 constitute a pair of locking claws 82a and 82b.

  The latch engaging portion 81a can be protruded to the outside (left side) of the guide hole 43 of the front plate 4 and immersed inside (right side) of the guide hole 43 by swinging of the swing latch 8 (swing body 81). It is configured. The left end surface of the latch engaging portion 81a is recessed in a substantially rectangular shape, and a magnet 81b is fitted into the recessed portion and fixed with screws. An inclined surface 91 that is inclined from the right front side (upper right side) to the left rear side (lower left side) is formed inside the latch receiver 9 provided in the left vertical frame 11. A suction plate 92 made of a ferromagnetic material is fixed with screws. The swing body 81 has a bottomed spring accommodating hole 84 that extends from the left end surface to the right side below the connecting pin 83, and a coil spring 85 is inserted into the spring accommodating hole 84. The coil spring 85 opens the door 2 when the latch engagement portion 81a moves in the immersion direction in which it is immersed in the guide hole 43, that is, when the engagement between the latch engagement portion 81a and the latch receiver 9 is released. It is biased to hold the locked state. The attractive force between the magnet 81b of the latch engaging portion 81a and the attracting plate 92 is set to be slightly larger than the urging force by the coil spring 85. Accordingly, when the door main body 20 moves to the closed position of the door where the latch engaging portion 81a and the latch receiver 9 face each other, the magnet 81b is attracted and moved to the suction plate 92, whereby the latch engaging portion 81a is moved to the latch receiver 9. The door 2 enters and the closed state (locked state) of the door 2 is maintained.

  Returning to FIGS. 4 and 5, in the plate handle 6, a locking plate 65 protrudes inward on the left side of each spring receiver 62. When viewed from the left-right direction, the locking plate 65 is configured such that its thickness decreases toward the distal end in the direction away from the base end. The locking plate 65 is arranged with the position in the horizontal direction being shifted by the pair of plate handles 6 and 6 while being shifted in the vertical direction. Specifically, as shown in FIG. 5, the locking plate 65 (hereinafter also referred to as the locking plate 65a) of the front plate handle 6 (hereinafter also referred to as the plate handle 6a) is in a state where the plate handle 6a is flat. The top surface of the tip of the fork 82 is disposed so as to come into contact with the locking claw 82a on the upper side of the fork 82 in the locked state. Similarly, as shown in FIG. 4, the locking plate (hereinafter also referred to as the locking plate 65b) of the rear plate handle 6 (hereinafter also referred to as the plate handle 6b) is in a state where the plate handle 6b is flat. The top surface of the tip is disposed so as to abut on the locking claw 82b on the lower side of the fork in the locked state.

-Door opening and closing operation-
Next, the door opening / closing operation will be described in detail.

  Hereinafter, a case where the door 2 is opened by operating the rear plate handle 6b will be described in detail. Specifically, first, the rear plate handle 6 b is pressed toward the inside (front side) of the door body 20 against the elasticity of the spring spring 69. When the plate handle 6b is pushed toward the inside of the door body 20, the locking plate 65a formed integrally with the plate handle 6b moves toward the inside of the door body 20 while slightly tilting in the left-right direction. Then, the locking claw 82a slides on the inclined surface of the locking plate 65a from the distal end portion toward the proximal end portion, and the fork 82 is pushed upward. Accordingly, the swing body 81 swings counterclockwise from the state of FIG. 6, and the latch engaging portion 81a (magnet 81b) is separated from the attracting plate 92. Further, when the plate handle 6 is pushed toward the inside of the door body 20, as shown in FIG. 7, the latch engaging portion 81a is drawn inside the guide hole 43, and the door 2 can be opened and closed. . FIGS. 8 and 9 show this state as viewed from above and below.
