Description

  In the present invention, a plurality of folding doors arranged inside a door frame provided in a building frame are arranged so as to be openable and closable, and a sealing member is rotatably provided in a storage groove formed on the indoor side of each folding door. In the folding door device in which the sealing member is rotated when the door is closed so that the floor surface and the folding door are made continuous by the sealing member, between the vertical frame of the door frame and the end of the sealing member. The present invention relates to an end seal structure in a folding door device for maintaining airtightness.

  Generally, a folding door is configured by connecting two door bodies through a joint rod so as to be rotatable, and allowing one free end to move along a guide rail of a building opening. A handle is provided on the door body, and the folding door can be opened and closed by pushing and pulling the handle outdoors or indoors. When the door is closed, all the door bodies are arranged flush with each other, and when the door is opened, the door body is folded.

  By the way, recently, a barrier-free structure has been adopted that makes it easy for elderly people and infants to move to the outdoor deck or balcony through the opening of the building or to move indoors when entering the indoor from the deck or balcony. There is a strong tendency to be. For this reason, there are increasing examples in which the upper surface of the lower frame of the sash, the floor surface on the indoor side, the deck surface on the outdoor side, and the floor surface of the balcony are designed to be substantially flush with each other.

  However, such barrier-free structures are mostly examples of sliding door sashes, and there is no barrier-free structure in the opening / closing structure provided with a folding door at the opening of the building.

  The reason is that airtightness and watertightness between the folding door and the lower frame of the door frame are difficult. That is, the structure in which the upper surface of the lower frame of the door frame, the floor surface on the indoor side, the deck surface on the outdoor side and the floor surface of the balcony are substantially flush with each other, prevents wind and rain from the outdoor side from entering the room. It is difficult.

  The lower frame of the conventional folding door has a structure with a step so that the indoor side is high and the outdoor side is low.In this way, the door body is separated from the lower frame when the door is opened. There is no problem. In addition, when the door is closed, the indoor side surface of the door frame is brought into contact with the stepped surface of the lower frame, so that airtightness and watertightness indoors and outdoors can be easily ensured.

  However, in the barrier-free structure, since the upper surface of the lower frame of the door frame is formed to be substantially horizontal, a gap is inevitably formed between the door body and the lower frame. The problem arises that the airtightness and watertightness between the door and the lower frame cannot be maintained.

As an improvement measure, as shown in Japanese Patent Application No. 2004-306750 and Japanese Patent Application No. 2004-216660, the floor surface around the lower frame of the door frame is flat when the door is opened, but the lower frame and the floor surface are closed when the door is closed. A structure in which a sealing member that seals the protrusion protrudes is conceivable.

  As shown in FIGS. 2 and 3, the door frame 1 and the folding doors 2 and 3 are composite sashes each including an outdoor-side metal portion p and an indoor-side synthetic resin portion q. As shown in FIG. 4, the door is configured to expand into a planar shape when the door is closed and to be folded to the outdoor side when the door is opened.

  The door frame 1 is formed by rectangularly framing an upper frame 1a, a lower frame 1b, and a vertical frame 1c, and is fixed to a door opening of a building housing (not shown). It is assumed that the indoor floor of the lower frame 1b is substantially flush with the indoor floor and the deck and balcony are substantially flush with the outdoor. The upper frame 1a and the lower frame 1b of the door frame 1 are formed with guide grooves 5 and 6 for folding doors along the outdoor longitudinal direction.

  Each of the folding doors 2 and 3 has two door bodies 9 rotatably connected via a joint rod 10 between a fixing rod 7 on the suspending side which is separated from each other and a door rod 8 which can be brought into contact with each other. It will be. A double glass 11 is mounted inside the door body 9. A roller bracket 12 is attached to the upper part of the fixed rod 7 and the door rod 8, and the roller rod 12 is slidably engaged with the guide groove 5 of the upper frame 1 a, so that the fixed rod 7 and the door rod 8 are engaged. In addition, two door bodies 9 and a joint rod 10 are suspended. A rotating roller 13 that rotates along the guide groove 6 of the lower frame 1b is provided at the lower part.

  Next, a storage groove 14 is formed along the indoor side of the guide groove 6 of the lower frame 1b, and two sealing members 15 corresponding to the folding doors 2 and 3 rotate inside the storage groove 14. It is stored freely. The length of the two sealing members 15 is substantially the same as the length of the storage groove 14. The indoor side of the storage groove 14 is also covered with the synthetic resin portion q. A part of the synthetic resin portion q is extended to form an angle piece 27 for fixing to the floor 25 on the indoor side of the lower frame 1b.

  An intermediate groove 17 is formed between the guide groove 6 and the storage groove 14 of the lower frame 1b. As shown in FIG. 5, a circular bulge 23 is formed at the upper end of the partition wall 18 of both grooves 14, 17. Is formed.

  As shown in FIG. 5, the sealing member 15 is rotatably supported on the upper end of the partition wall 18. The sealing member 15 has an engagement recess 19 formed on the outer side of the base of a hollow base portion 16 formed in a substantially fan shape by a metal extrusion mold, and a protruding edge 20 formed on the opposite side. A resin cover 21 is attached to the outer peripheral side of the base portion 16, and an airtight material 22 is attached to the upper portion. The sealing member 15 is formed in a sector shape as a whole.

  The engaging recess 19 of the sealing member 15 is engaged with the upper end bulging portion 23 of the partition wall 18 of the storage groove 14 and is rotatable about the center of the engaging portion as a rotation axis. The sealing member 15 is normally housed in the housing groove 14, and in this state, the tip of the projecting edge portion 20 projects in a substantially horizontal state in the intermediate groove 17.

  As shown in FIGS. 2 and 5, a lock rod 24 that can be operated from the outside is accommodated inside the joint rod 10 so as to be movable up and down. The lower portion of the lock rod 24 is branched into a fork between an outdoor lock portion 24a and an indoor operation rod 24b. The lock portion 24a is disposed so as to be insertable into the guide groove 6 of the lower frame 1b, and the operation rod 24b is disposed so as to be insertable into the intermediate groove 17.

  In the above configuration, when the folding door is folded and opened, the sealing member 15 is housed in the storage groove 14, and a part of the upper side surface portion and the airtight material 22 face the indoor side. . When the folding door 9 is unfolded and closed, as shown in FIG. 6, the lock rod 24 of each folding door is lowered and the outdoor side lock portion 24a is inserted into the guide groove 6 of the lower frame 1b. As a result, the folding door cannot be folded. At the same time, the actuating rod 24b is also lowered, enters the intermediate groove 17 of the lower frame 1b, engages with the protruding edge 20 of the sealing member 15, and is pushed down, so that the sealing member 15 rotates to be above the storage groove 14. The airtight material 22 abuts against the indoor side surface of the lower lid 9b of the folding door, the floor surface and the folding door are continuous, and the sealing member 15 closes the gap between the folding door and the indoor floor surface 25. Therefore, even with the barrier-free structure, airtightness and watertightness with the outside can be ensured.

  Next, in the folding door device, an end block 26 made of synthetic resin is fixed between the vertical frame 1c of the door frame and the end of the sealing member 15. As shown in FIGS. 5 to 9, the end block 26 includes a lower block 26 a and an upper block 26 b screwed thereon. The lower block 26a has a rectangular parallelepiped shape as shown in FIGS. 7A and 7B, and a concave portion 28 is formed at one end (on the side facing the end of the sealing member 15). The recess 28 is formed to be slightly larger than the movement trajectory of the tip arc portion of the sealing member 15 during rotation. The inner surface of the outer edge 29 of the recess 28 is formed in an arc shape.

  Moreover, the vertical groove 30 and the horizontal groove 31 are formed in the side surface which faces the outdoor side of the lower block 26a. The vertical groove 30 is disposed at a position corresponding to the airtight material 32 provided in the vertical frame 1c, is formed in a size that allows the lower end portion of the airtight material 32 to be fitted, and the horizontal groove 31 is formed in the sealing member 15. It is formed at a position where it abuts against the end of the provided airtight material 22, and the airtight material 33 is fitted therein.

  As shown in FIG. 8, the upper block 26b is formed to be narrower and smaller than the lower block 26a, and a drop bar receiving groove 34 and a long hole 35 are formed on the upper surface.

  The upper block 26b is fixed to the lower block 26a with a screw 36 inserted through the long hole 35. As described above, the reason why the attachment position can be adjusted by using the long hole 35 is that the load of the folding doors 2 and 3 is applied to the upper frame in the upper suspension system, and the center of the upper frame 1a is aging. There is a possibility that the portion may sag slightly, and the dropping rod 37 also tilts accordingly, so that the position of the receiving groove 34 that receives the dropping rod 37 can be changed corresponding to such a case. .

  The end block 26 is housed in the housing groove 14 of the lower frame 1b in a state where the airtight material 22 of the vertical frame 1c is fitted in the vertical groove 30, and is fixed by appropriate means. Thereby, the lower end of the airtight material 32 of the vertical groove 30 abuts on the upper surface of the airtight material 33 of the horizontal groove 31. Further, the end portion of the sealing member 15 is accommodated in the concave portion 28 at the end portion of the end block 26 and is covered by the outer edge 29 of the concave portion 28. Further, the end 15 a of the sealing member 15 is accommodated in the recess 28 at the end of the end block 26.

  Next, the operation mode of the end seal structure having the above configuration will be described. When the folding doors 2 and 3 are opened, there is no need for sealing, and the sealing member 15 is stored in the storage groove 14. On the other hand, when the door is closed, it is necessary to seal between the folding doors 2 and 3 and the door frame 1 (including the floor surface 25). First, the airtight material 32 of the vertical frame 1c of the door frame 1 and the vertical groove 30 of the end block 26 is brought into contact with the indoor side surface of the fixing door 7 of the folding door, and the airtight material 33 of the horizontal groove 31 of the end block 26 is folded. It abuts against the indoor side surface of the lower arm 34 of the door. Then, when the sealing member 15 is rotated upward, the space between the folding doors 2 and 3 and the floor surface 25 is sealed. Further, as shown in FIG. Fifteen airtight members 22 and airtight members 33 in the lateral grooves 31 of the end block 26 are continuous in a butt shape. Thus, the folding door fixing rod 7 comes into contact with the vertical frame 1c of the door frame and the airtight material 32 of the vertical groove 30 of the end block 26, and the lower lid 39 of the folding door is the airtight material of the sealing member 15 and the end block 26. 22 and 33.

  As described above, the end block 26 is fixed between the vertical frame 1c of the door frame and the end portion of the sealing member 15, and the end block 26 has an airtight material provided on the vertical frame 1c of the door frame. A vertical groove 30 for receiving the lower end portion of 32 and a horizontal groove 31 for fitting an airtight material 33 which can be abutted against the end portion of the airtight material 22 provided in the sealing member 15 are formed. Since the lower end of 32 is in contact with the upper surface of the airtight material 33 of the lateral groove 31, the airtight material 32 of the vertical frame 1 c and the airtight material 22 of the sealing member 15 are continuously connected via the airtight material 33 of the end block 26. Therefore, the seal between the end portion of the folding door device and the vertical frame 1c can be ensured satisfactorily.

  Further, the end portion 15a of the sealing member 15 is accommodated in the concave portion 28 at the end portion of the end block 26, and this end portion 15a is covered by the outer edge 29 of the concave portion 28. There is no gap between the block 26 and the block 26. Therefore, the outdoor air does not directly enter the indoor side, and a good indoor / outdoor seal can be secured.

  Therefore, it is possible to satisfactorily secure end seals at the corners of the folding door device and the vertical and lower frames of the door frame.

  In addition, as a sash with improved heat insulation, as in the example of the door frame and folding door described above, the part facing the outdoor side is made of an extruded metal material such as aluminum, and the part facing the indoor side is made of synthetic resin. In addition to those configured, there is also known a configuration in which a door frame and a folding door are each connected to an indoor member and an outdoor member made of a metal extrusion mold member via a heat insulating member made of synthetic resin. The lower frame structure of the door frame can also be applied to the latter folding door device. Of course, the lower frame structure of the door frame is applicable not only to a heat insulating sash, but also to a metal sash made of a metal such as aluminum.
