A pair of support ridges 64 are provided on the inner surface of the plate. The outer locking protrusion 63 is a protruding portion of a line formed by bending the ends of the outer locking fins 61 and 62 in a direction close to each other. The pair of support protrusions 64 are protruding portions of the wire provided in the portion closer to the base end side than the outer locking protrusion 63, and are parallel to each other and the outer locking protrusion 63. It is formed to have approximately the same protruding height. In addition, the code | symbol 65 in FIG. 4 is a connection board part provided so that between the base end parts of a pair of outward latching fin parts 61 and 62 might be connected.

  On the other hand, the upper frame 11 and the vertical frames 13 and 14 to which the decorative frame 60 is attached (hereinafter, when the upper frame 11 and the vertical frames 13 and 14 to which the decorative frame 60 is attached are collectively referred to as “basic frames 11, 13, and 14”). ) Are provided with a pair of inner locking fin portions 71 and 72, respectively. The pair of inner locking fin portions 71 and 72 are thin plate-like portions protruding so as to be parallel to each other from the finding surfaces located on the outdoor side of the basic frames 11, 13 and 14, and the distance between the outer surfaces of each other Is formed so as to be substantially equal to the distance between the outer locking protrusions 63 provided on the pair of outer locking fins 61 and 62. The inner locking fin portion 71 positioned on the outer peripheral side is formed so that the protruding length is substantially equal to the protruding length of the outer locking fin portions 61 and 62, while the inner locking fin portion 71 positioned on the inner peripheral side is The locking fin portion 72 is formed so that the protruding length is about 1/3 of the protruding length of the outer locking fin portions 61 and 62.

  Each of the inner locking fins 71 and 72 is provided with an inner locking protrusion (locking protrusion) 73 on the outer surface of the base end portion, and on the inner peripheral side having a small protruding length. The inner locking fin portion 72 is provided with an inclined surface 74. The inner locking protrusions 73 are line protruding portions protruding from the outer surfaces of the individual inner locking fins 71, 72, and a pair of outer locking fins 61 provided on the decorative frame 60. , 62 are disposed on the outdoor side of the outer locking protrusions 63 of the outer locking fin portions 61, 62 when the tips of the basic frames 11, 13, 14 are brought into contact with the end faces, respectively. And it is provided in the position which can be latched by the outward latching protrusion 63. The inclined surface 74 is provided at the distal end portion of the inner locking fin portion 72 having a small protruding length, and gradually becomes the outer peripheral side from the proximal end side to the distal end side of the inner locking fin portion 72. Inclined. As is apparent from FIGS. 2 to 4, the flat plate portion 75 provided with the inner locking fin portions 71, 72 in the pair of inner locking fin portions 71, 72 and the basic frames 11, 13, 14 includes the basic frame. 11, 13, and 14 are configured to be thicker than other portions.

  In order to attach the decorative frame 60 to the inner locking fin portions 71, 72 of the basic frames 11, 13, 14 configured as described above, a pair of outer locking fin portions 61, provided on the decorative frame 60, The inner locking fins 71 and 72 are inserted between the two, and the outer locking ridges 63 of the outer locking fins 61 and 62 are inserted at the positions over the inner locking ridges 73. What is necessary is just to make it latch to the inward latching protrusion part 73, respectively. At this time, since the inner locking protrusion 73 is formed on the base end side of the inner locking fins 71, 72, the deformation of the inner locking protrusion 73 is reduced, and the decorative frame 60 The fixing strength to the basic frames 11, 13, and 14 becomes stronger.

  At this time, in the above-mentioned joinery, the inner locking fin portion 71 located on the outer peripheral side protrudes larger than the inner locking fin portion 72 positioned on the inner peripheral side. The inner locking fin portion 71 having a large projecting dimension is inserted between the fin portions 61 and 62 first. In addition, an inclined surface 74 that is inclined so as to gradually become the outer peripheral side from the proximal end side toward the distal end side is provided at the distal end portion of the inner locking fin portion 72 having a small projecting dimension.

  Therefore, as shown by a two-dot chain line in FIG. 5, first, the inner locking fin portion 71 having a large projecting dimension is inserted between the outer locking fin portions 61 and 62 of the decorative frame 60, and the decorative frame 60. The outer locking ridge 63 of the outer locking fin 61 is engaged with the inner locking ridge 73 of the inner locking fin 71 in a state in which the front end is inclined so as to face the outer peripheral side. Stop. Thereafter, while maintaining this state, as shown by the solid line in FIG. 5, if the posture of the decorative frame 60 is moved so as to be perpendicular to the finding surface of the basic frames 11, 13, 14, the projecting dimension is large. The inner locking fin portion 71 serves as a guide so that the outer locking protrusion 63 of the outer locking fin portion 62 can be easily changed to the inner locking protrusion 73 of the inner locking fin portion 72, and As a result, the assembly work can be facilitated without damaging the inner locking fin portions 71, 72 and the outer locking fin portions 61, 62.

  In particular, when the decorative frame 60 is attached to the face of the upper frame 11, since the protruding dimension of the inner locking fin portion 71 located above is large, the pair of outer locking fin portions 61, 62 are not connected to each other. It is possible to place the decorative frame 60 on the inner locking fin portion 71 when the inner locking fin portion 71 having a large protruding dimension is inserted into the inner locking fin portion 71, and the assembling work of the decorative frame 60 is extremely easy. Become.

  Moreover, since a desired mounting strength can be ensured between the inner locking fin portion 71 having a large protruding dimension and the outer locking fin portion 61 locked thereto, a situation in which the mounting strength is insufficient. There is no fear of being invited. After the pair of outer locking fins 61 and 62 and the pair of inner locking fins 71 and 72 are locked to each other, the inner engagement is performed via the outer locking fins 61 on the outer peripheral side. The decorative frame 60 is fixed to the basic frames 11, 13, and 14 by screwing the attachment screws B into the stop fin portion 71. At this time, between the outer locking fin portion 61 and the inner locking fin portion 71 via a pair of support protrusions 64 provided on the inner surface of the outer locking fin portion 61 located on the outer peripheral side. Are pressed against each other.

  According to the fitting to which the decorative frame 60 is attached as described above, it is possible to improve the appearance quality as compared with the case in which the opening frame 10 is configured only by the basic frames 11, 13, and 14. Furthermore, as long as the dimensions of the outer locking fins 61, 62 provided on the decorative frame 60 are the same, the decorative frame 60 with different shapes and different decorations can be attached to the same basic frame 11, 13, 14. It is possible to configure the opening frame 10 with various specifications at a low cost by sharing the parts. Furthermore, after constructing the outer wall S on the outer peripheral portion of the decorative frame 60, it must pass through a pair of outer locking fin portions 61, 62 and a pair of inner locking fin portions 71, 72 locked to each other. In this case, water such as rainwater does not enter between the outer wall S and the housing K, which is advantageous in securing water tightness.

  By the way, as mentioned above, in the fitting from which the decorative frame 60 protrudes to the outdoor side, when the door 20 is largely opened, there is a possibility that the decorative frame 60 interferes with the decorative frame 60 and both are damaged. Such a situation is generally prevented by arranging a door stop on the floor or wall surface outside the room and limiting the opening of the door 20. However, a joinery that requires a door stop needs to secure a space for the door stop, and there are cases where the application location is restricted. Therefore, in the joinery of the present embodiment, as shown in FIG. 3, the door 20 and the decorative frame 60 are provided by providing the edge member 80 on the suspension base surface 21 of the door 20 and providing the buffer member 90 on the suspension base frame 14. To prevent interference.

  The edge member 80 is provided so as to cover the suspension base surface 21 of the door 20 over the entire length, and has a guide surface 81 at a corner portion located on the outdoor side. The guide surface 81 is a cylindrical convex surface having an arc shape centered on the rotation axis C of the door 20.

  As shown in FIG. 6, the buffer member 90 is a long member having a substantially trapezoidal cross section formed of a synthetic resin material having elasticity such as rubber. The buffer member 90 has a mounting tab 91 having a substantially T-shaped cross section at the base end, and the mounting tab 91 is mounted between a pair of locking strips 14 a provided on the suspension frame 14. Thus, it is disposed over the entire length of the edge located on the outdoor side of the prospective surface of the suspension base frame 14. In the synthetic resin material constituting the buffer member 90, the base end portion provided with the mounting tab 91 is configured to be hard, while the tip end portion contacting the door 20 is formed soft. The protrusion height of the buffer member 90 can contact the door 20 before contacting the decorative frame 60 provided on the suspension frame 14 when the door 20 is rotated to the outdoor side around the rotation axis C. The dimensions are set.

  A contact piece 92 is formed integrally with the buffer member 90. The abutting piece 92 is a fin-like portion that protrudes from the tip of the buffer member 90 toward the indoor side, and protrudes toward the guide surface 81 provided on the suspension base surface 21 when no external force is applied. It is formed in an arc shape so that The resin material constituting the contact piece 92 is soft like the tip of the buffer member 90. A notch 93 is formed in the connecting portion between the buffer member 90 and the contact piece 92 from the surface located on the indoor side. The notch 93 is a groove-like portion that deforms as a broken line when the contact piece 92 receives an external force toward the indoor side. The length of the contact piece 92 is set to a dimension that allows the contact piece 92 to continuously contact the guide surface 81 of the edge member 80 or the surface of the door 20 while the door 20 is opened from the closed state until it contacts the buffer member 90. It is.

  That is, when the door 20 is in a closed state, the contact piece 92 of the buffer member 90 is in contact with the guide surface 81 of the edge member 80 via its tip as shown in FIG. The tip of the abutting piece 92 is in the state facing the indoor side, and is in pressure contact with the guide surface 81 of the edge member 80 via an outer surface that is convex in an arc shape. In this state, the space between the suspending frame 14 and the door 20 is covered with the contact piece 92 and the buffer member 90 that are in contact with each other. It is possible to prevent foreign objects such as fingers from entering.

  When the electric lock 50 is released from this state and the door 20 is opened to the outdoor side, the door end side moves to the outdoor side, while the guide surface 81 of the edge member 80 located on the suspending side from the rotation axis C is the chamber. The abutting piece 92 that is in pressure contact with the guide surface 81 is also drawn into the indoor side, and the part that forms itself and the notch 93 is elastically deformed.

  Here, when the elastic deformation of the contact piece 92 and the notch 93 increases as the opening degree of the door 20 increases, the operation force when rotating the door 20 in the opening direction also increases, and the operability point is increased. It is not preferable. However, the above-mentioned contact piece 92 of the joinery is provided with the front end facing the indoor side, and coincides with the retracting direction of the guide surface 81 when the door 20 rotates in the opening direction. There is no interposition between the guide surface 81 and the suspension base frame 14 in a stretched manner. In addition, when the door 20 is opened, the amount of elastic deformation increases because the amount of deformation is reset by appropriately deforming the contact piece 92 in a direction away from the guide surface 81 of the edge member 80. The contact state with the guide surface 81 is maintained. Therefore, it is possible to ensure a desired sealing property between the suspension frame 14 and the door 20 without increasing the operating force when opening the door 20.

  When the door 20 is further opened, the front end portion of the contact piece 92 passes through the guide surface 81 of the edge member 80 and then comes into contact with the surface of the door 20, and the contact piece 92 comes close to the buffer member 90 through the notch 93. The abutting state with the door 20 is maintained while appropriately bending in the direction of turning. After that, the door 20 comes into contact with the buffer member 90 via the contact piece 92 and the opening degree thereof is limited, and the situation where the decorative frame 60 and the door 20 interfere with each other can be prevented. During this time, according to the joinery described above, the space between the suspension base frame 14 and the door 20 is continuously covered by the buffer member 90 and the contact piece 92 until the door 20 is fully opened from the closed state. Thus, not only the entry of foreign matter such as sand dust can be prevented, but also the situation where the wiring cable 51 of the electric lock 50 disposed between the suspension frame 14 and the door 20 is exposed to the outside is prevented. Will be able to.

  If the door 20 is closed from the fully opened position, the state shown in FIG. 3 is restored. Therefore, the contact piece 92 is bent in the direction approaching the buffer member 90 through the notch 93 only when the door 20 is fully opened, and even when used for a long time. There is no possibility that creep will occur in the contact piece 92 or the notch 93.

  As described above, according to the fitting described above, since the protruding dimensions of the pair of inner locking fin portions 71 and 72 are different, the inner locking fin portion 71 having a large protruding dimension is formed on the decorative frame 60. Inserted between the outer locking fin portions 61, 62, the inner locking fin portion 72 having a small protruding dimension is guided by the inner locking fin portion 71 as a pair of outer locking fin portions. It becomes possible to insert between 61 and 62 easily and reliably. Moreover, since a desired mounting strength can be ensured between the inner locking fin portion 71 having a large protruding dimension and the outer locking fin portion 61 locked thereto, a situation in which the mounting strength is insufficient. There is no fear of being invited.

  In the embodiment described above, in the fitting provided in the entrance provided with the opening frame 10 and the door 20, the one in which the decorative frame 60 is provided on the finding surface located on the outdoor side of the opening frame 10 is illustrated. However, the present invention is not limited to this, and it may be applied to other fittings such as a fitting having a glass window in the opening frame, or a decorative frame may be provided on a finding surface located on the indoor side. Further, the basic frame for providing the decorative frame need not be the upper frame and the pair of left and right vertical frames, and may be only the upper frame, or the decorative frame may be provided for all the frames including the lower frame. good. Furthermore, although what was shape | molded as aluminum or aluminum alloy is illustrated as a decorative frame, it is not necessarily limited to this, For example, a decorative frame can also be comprised with a synthetic resin material.
