Description

  The present invention relates to a fitting having a ventilation frame member provided with a ventilation mechanism.

  Some fittings include a ventilation mechanism. As the ventilation mechanism, those provided directly on the upper and lower frames of the shoji screen and those provided on a dedicated ventilation frame are also provided. The ventilation frame is, for example, juxtaposed on the inner peripheral side of the upper frame and serves as a member for supporting the upper edge of the face material. According to the fitting provided with the ventilation frame, there is an advantage that a ventilation function can be added after applying a normal fitting for the upper frame and the lower frame of the sliding door (for example, see Patent Document 1).

JP 2013-28985 A

  By the way, in the above-mentioned fittings, both ends of the ventilation frame are sandwiched between the support fins of the vertical frame and the ridge. For this reason, the ridge mounted on the vertical frame is disposed over the surface of the face material and the surface of the ventilation frame.

  Here, the ridge is to secure airtightness and watertightness with the face material by originally supporting the surface of the face material. Therefore, it is not preferable that a gap is formed between the ridge and the surface of the face material or between the ridge and the surface of the ventilation frame. In the above-described fittings, a spacer is interposed between the ridge and the ventilation frame, thereby preventing a gap from being formed between them. However, the surface of the ventilation frame may protrude from the surface of the surface material depending on the mounting state of the surface material or the ventilation frame. In such a situation, it is difficult to prevent a situation in which a gap is formed between the ridge and the surface of the face material, which may affect airtightness and watertightness. In addition, the above-mentioned problem is not limited to the case where a dedicated ventilation frame is provided on a shoji screen, and the same applies to a case where a dedicated ventilation frame material is provided on a frame body having a frame material directly supported by a frame material such as a FIX window. Can occur.

  The present invention has been made in view of the above circumstances, and has as its object to provide a fitting that can support a ventilation frame member without affecting airtightness or watertightness.

  In order to achieve the above object, a fitting according to the present invention includes two support frame members arranged at an interval from each other, and a ventilation frame member provided so as to bridge between the two support frame members. The support frame member is provided with a support fin portion for supporting one surface of the face material, and a mounting groove for mounting a ridge for supporting the other surface of the face material is provided. The ventilation frame material includes a ventilation mechanism that allows ventilation along a prospective direction between cap members attached to both ends, and supports the support frame material via one wall of the cap member. It is supported by a fin portion, and between the cap member and the support frame member, the cap member restricts movement in a direction away from the support fin portion, and is configured separately from the pressing edge. Characterized in that the regulating means is provided.

  According to the present invention, the cap member of the ventilation frame member is supported by the regulating means separate from the pressing edge and the support fin of the support frame member. For this reason, it is not necessary to clamp the cap member by the ridge, and the difference between the surface position of the cap member and the surface of the panel does not affect the relative position between the ridge and the surface of the panel. Thereby, it becomes possible to support the ventilation frame member without affecting the airtightness and the watertightness.

When the ventilation frame 30 is mounted, an adhesive or a double-sided tape is attached to the mounting surface 31b of the mounting portion 31 facing the room and the side wall portion 43 of the cap member 40 located on the room side. Then, as shown in FIG. 2 and FIG. 6A, while the engaging fin portion 31a is inserted into the mounting groove 203 of the upper frame 22 with the engaging member 53 held at the retracted position, the interior of the mounting portion 31 is indoors. Is pressed against the support fin portion 202 of the upper frame 22 to be supported, and the side wall portion 43 located on the indoor side of the cap member 40 is pressed against the support fin portion 202 of the vertical frame 21 to be supported.

  At this time, the engaging member 53 held at the evacuation position does not interfere with the vertical frame 21 and does not impair workability when the ventilation frame 30 is attached. After the finding surface 31b facing the room of the mounting portion 31 and the side wall portion 43 located on the room side of the cap member 40 are supported by the corresponding supporting fin portions 202, for example, the two side wall portions 42 of the cap member 40 are provided. , 43, a tool is inserted, and the engaging member 53 is rotated to be positioned at the engaging position. Thereby, as shown in FIG. 6B, the engagement plate portion 53 a projecting from the edge of the side wall portions 42 and 43 is inserted into the mounting groove 203 of the vertical frame 21.

It will be in the state that was done. Further, cap members 40 provided at both ends of the ventilation frame 30 are bonded to the support fin portions 202 of the vertical frame 21, and the engagement ends 53 c of the engagement members 53 are engaged with the mounting grooves 203 of the vertical frame 21. State. As a result, the ventilation frame 30 is attached to the frame set 24 with the movement along the expected direction and the movement in the vertical direction with respect to the upper frame 22 and the vertical frame 21 being restricted. Thereafter, the face material 25 is arranged in a region surrounded by the left and right vertical frames 21, the ventilation frame 30 and the lower frame 23, and, for example, one surface of the face material 25 is bonded to the respective support fin portions 202 and the support plate portions 32b. At the same time, if the ridge 26 is mounted on each of the mounting groove 203 and the auxiliary mounting groove 32c, the ridge 26 supports the other surface of the face material 25. This makes it possible to form the shoji screens 20A and 20B in which the face material 25 is supported between the support fin portion 202 and the support plate portion 32b and the pressing edge 26. In the first embodiment, similarly to the frame members 21, 22 and 23, a joining surface of 45 ° is formed at both ends of the pressing edge 26.

Moreover, the cap member 40 of the ventilation frame 30 is in a state in which all the side walls 42 on the outdoor side are exposed to the outside. In other words, the ridges 26 attached to the frame members 21, 22, 23 and the ventilation frame 30 are all arranged only on the surface of the face material 25, and are not configured to cover the cap member 40. Therefore, even if there is a difference between the surface position of the face material 25 and the surface position of the cap member 40, the difference does not affect the relative position between the pressing edge 26 and the surface of the face material 25, and There is no possibility that the airtightness and the watertightness with the face material 25 are impaired.

In addition, since the engaging member 53 provided on the cap member 40 is inserted into the mounting groove 203 of the vertical frame 21, the movement of the cap member 40 in the direction away from the support fin portion 202 of the vertical frame 21 is restricted. . Accordingly, there is no possibility that the cap member 40 projects from the vertical frame 21. Further, as the frame members 21, 22, 23 constituting the frame set 24, not only frame members having the same cross-sectional shape on four circumferences can be applied, but also frame members having no ventilation mechanism. It can be diverted, which is advantageous in terms of design and manufacturing cost.

  In the first embodiment, the lock plate portion 53b of the engagement member 53 is held at the retracted position by engaging the elastic engagement piece 45 provided on the cap member 40 with the lock plate portion 53b. It is not limited to. For example, like the lock unit 50 'of the first modification shown in FIGS. 9 and 10, the holding base portion 54 having the screw insertion hole 54a is provided on the mounting base 51, and the lock hole 53d of the lock plate portion 53b is screwed. It may be changed to the hole 53e, and the screw 55 may be screwed into the screw hole 53e of the lock plate 53b via the screw insertion hole 54a of the holding piece 54 when the engaging member 53 is located at the retracted position. good.
