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, the present invention relates to an adjacent adjacent sealing structure.

  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.

  Thus, 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. Sometimes the problem arises that the airtightness and watertightness between the folding 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.
JP 2003-193756 A

  By the way, since the sealing member is provided corresponding to each folding door, if there are a plurality of folding doors, the same number of sealing members are arranged in series. In that case, if a gap is formed between adjacent end portions of adjacent sealing members, outside air enters the room. However, if the structure is such that the adjacent end abuts to close the gap, the adjacent end interferes when only one of the folding doors is closed, so that the opening and closing operation is difficult to perform smoothly due to the frictional force. There is a problem. Thus, in the conventional folding door apparatus, the process of the adjacent edge part of the member for sealing is not necessarily enough, but there existed a problem in airtightness and operativity.

  The present invention solves the above problems, and provides an adjacent seal structure in a folding door device that can secure sufficient airtightness between adjacent end portions of a sealing member and can be independently rotated. Let that be the issue.

In order to solve the above-mentioned problem, the invention according to claim 1 has a door frame and a folding door, the lower frame upper surface of the door frame is substantially flush with the floor surface, and the folding door is provided inside the door frame. A plurality of sealing members that can be folded and unfolded and stored in series inside the storage groove formed on the indoor side of the lower frame and that can rotate and protrude above the storage groove are serially stored in the folding door . The present invention is directed to a folding door device in which the sealing member is rotated by a lock rod provided so as to protrude from the storage groove, and the lower portion of the folding door and the floor surface are continuously sealed via the sealing member. .

  In such a folding door device, end covers are respectively attached to adjacent end portions of adjacent sealing members, and the side surface of one end cover of the opposite side surfaces of the both end covers has a sealing member on the side surface. An arc-shaped convex portion along an arc centered on the rotation axis is formed so as to protrude toward the other end cover side, and a circle along the arc centered on the rotation axis is formed on the side surface of the other end cover. An arcuate groove is formed, and the arcuate convex portion is fitted into the arcuate groove.

  In addition, a fitting means here the fitting state of a grade which an arc-shaped convex part and an arc-shaped recessed part do not interfere with each other.

The invention according to claim 2 is characterized in that the door frame and the folding door are each composed of a metal part and a synthetic resin part, respectively. The part cover is press-fitted into a hollow part formed in the longitudinal direction of the corresponding sealing member.

  According to a fourth aspect of the present invention, an extension portion formed by extending an airtight material of the sealing member is attached to each end portion cover, and when the two end portion covers are adjacent to each other, The extension portion is also in a butted state.

  Here, the term “butting” includes not only abutting each other but also a state in which there is a slight gap.

  According to the first aspect of the present invention, the plurality of sealing members are arranged in series in the guide groove, the end covers are respectively attached to the adjacent end portions of the adjacent sealing members, and the opposing side surfaces of the both end covers are arranged. Of these, the side surface of one end cover is formed with an arc-shaped convex portion along the arc centering on the rotation axis of the sealing member so as to protrude toward the other end cover, and the other end cover Since the arc-shaped groove portion along the arc centering on the rotation axis is formed on the side surface and the arc-shaped convex portion is fitted to the arc-shaped groove portion, only one sealing member is rotated. However, the arc-shaped convex portion and the arc-shaped groove portion do not interfere with each other. Therefore, each can be independently rotated.

  In addition, when the arcuate convex portion is fitted in the arcuate groove portion, the arcuate convex portion and the arcuate groove portion overlap each other when viewed indoors or outdoors. A direct gap that can be seen from the inside and outside of the room is not formed between both end covers provided in the section. Therefore, since the outside air cannot enter the indoor side directly from the adjacent end portion, airtightness can be ensured.

  According to the invention which concerns on Claim 2, since the said door frame and the folding door are each comprised from the metal part and the synthetic resin part, the indoor and outdoor heat insulation can be ensured further.

  According to the invention which concerns on Claim 3, what is necessary is just to press-fit in the hollow part formed in the longitudinal direction of the member for a respectively corresponding seal. Each end cover can be securely attached only by press-fitting because the other end cover cannot get out of the way. Therefore, attachment is easy.

  According to the invention which concerns on Claim 4, since the extension part of the airtight material attached to the member for a seal | sticker is attached to the edge part cover which adjoins, and it has come to contact | abut each other, airtightness is ensured favorable.

  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. Inside the storage groove 14, two sealing members 15a and 15b corresponding to the folding doors 2 and 3 are provided. They are stored in series. The lengths of the two sealing members 15 a and 15 b are 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, and an angle piece 27 for fixing to the floor surface on the indoor side of the lower frame 1b is formed.

  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 members 15 a and 15 b are rotatably supported on the upper end of the partition wall 18. In the sealing members 15a and 15b, an engagement recess 19 is formed on the outer side of the base portion of the hollow base portion 16 formed in a substantially fan shape by a metal extrusion mold, and a protruding edge portion 20 is 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 members 15a and 15b are formed in a sector shape as a whole.

  The engaging recess 19 of the sealing member 15a, 15b 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 members 15a and 15b are normally housed in the housing groove 14, and in this state, the tip of the projecting edge portion 20 projects into the intermediate groove 17 in a substantially horizontal state.

  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 members 15a and 15b are accommodated in the storage groove 14, and a part of the side surface portion on the upper side and the airtight material 22 face the indoor side. ing. 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 lowered and enters the intermediate groove 17 of the lower frame 1b and engages and pushes down the projecting edge portion 20 of the sealing members 15a and 15b. 14, the airtight material abuts against the indoor side surface of the lower lid 9 b of the folding door, whereby the floor surface 25 and the folding doors 2 and 3 are continuous, and the sealing members 15 a and 15 b are connected to the folding door 2, 3 and the floor 25 on the indoor side are closed, so that airtightness and watertightness with the outside can be ensured even with a barrier-free structure.

  Next, end covers 26a and 26b are attached to adjacent end portions of the adjacent sealing members 15a and 15b, respectively. As shown in FIGS. 7A to 7D, one end cover 26a is formed with a fan-shaped portion 28 in accordance with the sectional shape of the sealing members 15a and 15b (including the base portion 16 and the cover 21). A projecting edge portion 29 and an engaging recess portion 30 are formed, and an airtight material fitting groove 31 is formed. One side surface of the plate portion 26a can be engaged with a protrusion 33 that can be press-fitted into the hollow portion 32 (see FIG. 5) of the base portion 16 of the sealing members 15a and 15b and the end portions of the sealing members 15a and 15b. An arcuate collar 34 is formed, and on the opposite side, the side facing the other end cover 26b is an arcuate convex 35 along an arc centering on the rotation axis of the sealing members 15a, 15b. Is formed so as to protrude toward the other end cover 26b.

  On the other hand, the other end cover 26b is also provided with a fan-shaped portion 36, a projecting edge portion 37, and an engaging recess 38, as well as the one end cover 26a, and an airtight material fitting groove 39. Is formed. Also, on one side surface, similar to the one end cover 26a, there is a protrusion 40 that can be press-fitted into the hollow portion 32 of the base portion 16 of the sealing members 15a and 15b, and the end portions of the sealing members 15a and 15b. An arcuate collar 41 that can be engaged is formed. An arcuate groove portion 42 is formed on the side surface facing the one end cover 26a along the arc centered on the rotation shaft.

  When attaching the end covers 26a and 26b to the sealing members 15a and 15b, as shown in FIGS. 9A and 9B, the arc-shaped flanges 34 and 41 of the end covers 26a and 26b are sealed. The protrusions 33 and 40 of the end covers 26a and 26b may be pressed into the hollow portions 32 formed in the longitudinal direction of the seal members 15a and 15b while being engaged with the cover 21 of the members 15a and 15b. As shown in FIGS. 10A and 10B, the sealing members 15a and 15b of the sealing members 15a and 15b extend toward the end cover 26a and 26b, and the extended portions 22a and 22b are connected to the end portions. The cover 26a, 26b is fitted and mounted in the airtight material fitting grooves 31, 39. Then, when the two end covers 26a and 26b are adjacent to each other, the extension portions 22a and 22b of the both airtight materials are also brought into contact with each other. Then, as shown in FIG. 9B, the arcuate convex portion 35 of one end cover 26a is fitted into the arcuate groove portion 42 of the other end cover 27a.

  Each end cover 26a, 26b can be securely attached only by press fitting because the other end cover 26b, 26a cannot get out of the other end cover 26b, 26a. Therefore, attachment is easy.

  Next, the rotation mode of the two sealing members 15a and 15b will be described. When both the sealing members 15a and 15b are housed in the housing groove 14, that is, when the two folding doors 2 and 3 are in the open state, as shown in FIGS. 11 (a) and 11 (b), Both the sealing members 15 a and 15 b do not protrude above the storage groove 14. Also, as shown in FIGS. 12 (a) and 12 (b), when both sealing members 15a and 15b rotate and protrude from the storage groove 14, that is, when the two folding doors 2 and 3 are in a closed state. Both the sealing members 15a and 15b protrude above the storage groove 14, and seal the indoor side of the folding doors 2 and 3 as shown in FIG. In this case, the airtight material extensions 22a and 22b attached to the sealing members 15a and 15b are attached to the adjacent end covers 26a and 26b so as to be brought into contact with each other, so that airtightness is ensured. The

  On the other hand, when one sealing member 15a rotates and protrudes upward and the other sealing member 15b is stored in the storage groove 14, as shown in FIGS. 13 (a) and 13 (b). Since one sealing member 15a rotates about the rotation axis, as shown in FIG. 14, the arc-shaped convex portion 35 of the end cover 26a passes through the arc-shaped groove 42 with the rotation axis. Move to draw a circular arc around the center. When only the other end cover 26b rotates, the arc-shaped groove 42 moves similarly. Therefore, even if only one sealing member 15a or 15b is rotated, the arc-shaped convex portions 35 and the arc-shaped groove portions 42 of the two end covers 26a and 26b do not interfere with each other. Therefore, each can be independently rotated.

  Further, the state in which the arc-shaped convex portion 35 is fitted in the arc-shaped groove portion 42 is a state in which the arc-shaped convex portion 35 and the arc-shaped groove portion 42 overlap each other when viewed indoors or outdoors. A direct gap that can be seen from the inside and outside of the room is not formed between both end covers 26a and 26b provided at adjacent ends of the members 15a and 15b. Therefore, since the outside air cannot enter the indoor side directly from the adjacent end portion, airtightness can be ensured.

  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.
