Description

  The present invention relates to a joinery in which a frame and an angle are fixed.

Conventionally, in joinery, the following two types of angle structures for connecting a frame body to a frame such as a frame are known.
For example, in the sash frame with an angle described in Patent Document 1, a small gap is formed between the lower frame and the frame. One mounting piece of an angle member made of an aluminum alloy extruded shape member having a substantially L-shaped cross section is inserted into the gap and fixed to the frame body with a screw. The other mounting piece of the angle member is fixed to the upper surface of the frame with screws. And the cover material is mounted on the upper surface of the other mounting piece of the angle member, and is fitted between the upper end of the frame and the frame to be concealed.

  However, since the angle of the sash frame described in Patent Document 1 described above is screwed to the frame body with one attachment piece inserted into the gap, even if the angle is cracked or damaged after installation Could not be removed.

  In addition, the angle 104 of the latter sash frame is fixed after the attachment because the both ends of the lower stage of the angle 104 are fixed by the two locking portions of the indoor side wall surface of the lower frame 101 and the base of the rail 103. It was difficult to remove the part. Therefore, when the angle 104 is cracked or damaged after the angle 104 is attached and used, it is difficult to remove or replace the angle 104.

  This invention is made | formed in view of such a subject, Comprising: It aims at providing the fitting which can attach and remove an angle easily.

The joinery according to the present invention includes a frame body that houses a shoji, and an angle that is installed in a gap formed between the frame body and the indoor side member, and is provided in one of the frame body and the angle in the gap. The engaging portion and the engagement receiving portion provided on the other side are arranged to be engaged with each other.
According to the present invention, an angle is set on the gap between the frame body and the indoor side member, and the engagement portion provided on the frame body and the angle is engaged with the engagement receiving portion in the gap to thereby reduce the angle. In addition to being able to be attached to the frame, it is possible to disengage the engagement between the locking portion and the engagement receiving portion by pulling the angle.
The angle may be either a resin angle or a metal angle. However, if the resin angle is used, the thermal conductivity can be reduced and condensation can be reduced.

Moreover, it is preferable to provide an elastically deformable contact portion that extends into the gap and contacts the frame body or the indoor side member on the indoor side in the prospective direction of the locking portion or the engagement receiving portion formed in an angle.
The angle engaged and fixed to the frame body is provided with an abutting portion that abuts against the wall surface of the frame body or the indoor side member on the indoor side of the prospective direction separately from the locking portion or the engagement receiving portion engaged with the frame body. Therefore, the heat insulation can be enhanced by the contact portion. In addition, when the angle is removed, if the angle on the frame body side is pulled apart, the abutment part is elastically deformed so that the locking part and the engagement receiving part can be detached, so that the removal is easy and even if the angle is damaged Can be removed.

Further, the angle may be made of resin, and a contact portion extending so as to surround the locking portion or the engagement receiving portion may be provided on the indoor side in the prospective direction of the locking portion or the engagement receiving portion provided in the angle.
By providing the resin angle, a heat insulating layer can be formed and condensation can be reduced.

Moreover, you may provide a fin part in the outdoor side edge part of an angle.
Thereby, airtightness can be improved by making the fin part provided in the angle contact a shoji.
In addition, an airtight material that abuts on the other of the frame and the shoji may be provided, and the airtightness can be improved in, for example, a building.

  In the joinery according to the present invention, the angle can be fixed to the frame body by engaging the engaging portion and the engaging receiving portion of the frame body and the angle in the gap between the frame body and the indoor side member. Since the receiving portion is positioned in the gap on the indoor side of the frame body, the engagement between the engaging portion and the engagement receiving portion can be disengaged and removed by pulling the angle. Therefore, it is easy to attach and remove the angle to the frame.

The inner shoji 7 and the outer shoji 8 are each formed into a quadrangular frame shape with an upper eave 10 and a lower eave 11 and left and right vertical eaves 12 and 13, and a multi-layer glass 9 such as a pair glass is housed therein. .
1 and 3, the upper frame 2 of the frame 5 is mainly formed of a metal upper frame 15, and an upper resin angle 16 made of resin is connected to the indoor side surface thereof. The metal upper frame 15 has an outdoor side hanging piece 15b hanging from the outdoor side end, an intermediate rail portion 15c hanging from the intermediate side, and an indoor side hanging from the indoor side end as viewed in the prospective direction of the base portion 15a forming the upper surface. And a hanging piece 15d.

An intermediate resin frame 17 having a substantially comb-shaped cross section is connected to the intermediate rail portion 15c on the indoor side, and a substantially plate-shaped inner resin frame 18 is brought into contact with the outdoor side surface of the indoor side hanging piece portion 15d. Yes. Moreover, the intermediate resin frame 17 and the inner resin frame 18 are connected by a resin coupling plate 14 and engaged with the base portion 15a. The indoor indoor hanging piece 15d is surrounded by the inner resin frame 18 and the upper resin angle 16 on the indoor and outdoor surfaces a1 and a2.
And the outer shoji 8 is hold | maintained so that driving | running | working is possible between the outdoor side drooping piece part 15b and the intermediate | middle rail part 15c. The inner shovel 7 is also movably held between the intermediate rail portion 15c and the indoor hanging portion 15d.
1 and 4, the lower frame 3 is mainly formed of a metal lower frame 19, and an outer rail 20 is formed in the outdoor region as viewed from the prospective direction of the metal lower frame 19, and the indoor region An inner rail 21 is formed. A door (not shown) of the outer shoji 8 is placed on the outer rail 20 so as to be able to travel, and the inner wheel 21 is placed so as to be able to run on the inner rail 21 so as to receive the loads of the outer shoji 8 and the inner shoji 7, respectively. ing. A lower resin angle 24 made of a resin having a substantially L-shaped cross section is detachably installed at an indoor side end portion of the metal lower frame 19 with a wooden frame 22 shown in FIG.

In FIG. 2, the left and right vertical frames 4 are mainly formed of a metal vertical frame 25, and a resin vertical frame 26 having a plurality of hollow portions formed on the indoor side of the left metal vertical frame 25 is connected to the right metal vertical frame 25. A side resin angle 27 having the same configuration as that of the upper resin angle 16 is connected to the indoor side of the frame 25.
Further, the outer shoji 8 and the inner shoji 7 are configured such that the four sides of the double-glazed glass 9 are composed of an upper eyelid 10, a lower eyelid 11, and left and right longitudinal rods 12 and 13. The multi-layer glass 9 is supported at its four side edges by glass receiving portions 34 provided on the upper metal rod 10a, the lower metal rod 11a, and the left and right metal vertical rods 12a and 13a through glazing channels. The indoor side of these metal cages is covered with an upper resin cage 10b, a lower resin cage 11b, and left and right resin longitudinal rods 12b and 13b, respectively.
In addition, the metal upper frame 15, the metal lower frame 19, the left and right metal vertical frames 25, the metal upper rod 10a, the metal lower rod 11a, and the left and right metal vertical rods 12a and 13a are made of, for example, an aluminum alloy.

Next, an air-tight structure and a heat insulating structure between the metal upper frame 15 of the upper frame 2 and the upper collar 10 of the inner shoji 7 will be described with reference to FIG. An indoor side hanging piece 15d formed at the indoor side end of the metal upper frame 15 is suspended from the base 15a, and a receiving portion 35 is formed on the outdoor side surface a2 of the lower end thereof. For example, an elastic aluminum alloy sealing member 36 is fitted as an airtight material in the receiving portion 35, and the tip of the sealing portion 36 abuts on the surface portion 10 aa formed on the indoor side of the metal upper collar 10 a of the inner shroud 7. It is airtightly sealed.
An elastic member such as rubber may be used as the airtight material instead of a metal such as an aluminum alloy. Also. An engagement receiving portion 37 is formed on the indoor side surface a2 of the indoor side hanging piece 15d.

The resin upper resin angle 16 engaged with the indoor-side hanging piece 15d of the metal upper frame 15 has a main body portion 16b provided with a stepped portion 16a, and the tip piece 16c is an indoor-side hanging piece. The lower end of the portion 15d is contacted and covered.
Further, the upper resin angle 16 has a locking piece that can be engaged with the engagement receiving portion 37 with the base abutting on the indoor side hanging piece 15d near the stepped portion 16a and the distal end bent toward the indoor side. 38 (locking portion). Further, the upper resin angle 16 extends upward from the main body portion 16b and bends or curves at the distal end side so as to surround the locking piece 38 and comes into contact with the indoor hanging portion 15d (contact portion). ) Is formed.
Further, at the corner of the stepped portion 16a, a fin portion 40 made of a soft resin is connected or integrally formed on the outdoor side, that is, toward the upper collar 10 of the inner shoji 7. The soft resin of the fin portion 40 is softer than other resins and is formed so as to be elastically deformable, and is in contact with the upper collar 10 of the inner pouch 7. When the inner impeller 7 is caused to travel, it is displaced while the fin portion 40 is in contact therewith, and the airtight state is maintained.
In addition, the fin part 40 may be formed of a relatively hard resin like other resins, and in this case, it is preferable that the fin part 40 is close to the upper collar 10 of the inner limb 7 without contact. .

On the other hand, on the upper collar 10 of the inner shovel 7, the indoor side end portion of the metal upper collar 10 a has, for example, a vertically extending surface portion 10 aa that is in contact with the seal member 36 of the upper resin angle 16 and hermetically seals. The sealing member 36 and the surface portion 10aa constitute an airtight line that prevents the outside air from being ventilated indoors.
Further, the resin upper collar 10b connected to the metal upper collar 10a on the indoor side forms an indoor vertical section 10ba in which the portion with which the fin portion 40 abuts forms, for example, a planar shape. Further, the lower portion is formed with a tapered portion 10bb which is inclined so as to widen toward the indoor side, and further, a concave portion 10bc having a protrusion at the tip is formed on the lower side.
The resin upper collar 10b may be formed of a soft resin so that it does not come into contact with the upper frame 2 and is damaged when the inner impeller 7 is removed from the frame 5 to the indoor side.

Therefore, the stepped portion 16a, the tip piece 16c, and the fin portion 40 of the upper resin angle 16 constitute a substantially U-shaped heat insulation layer 42 that insulates cold air transmitted from the outdoor side, and constitutes a heat insulation line. To do. Moreover, even when the dew condensation adhering to the surfaces a1 and a2 of the indoor side hanging piece 15d falls along the surfaces a1 and a2, it can be held by the heat insulating layer 42. Furthermore, even if the dew condensation water flows from the heat insulating layer 42 through the soft fin portion 40 to the resin upper tub 10b, it can be stored in the recess 10bc. In the heat insulating layer 42, the tip piece 16 c is not in contact with the upper flange 10 and the fin portion 40 is in contact, but the fin portion 40 may be in non-contact as long as it extends to a position close to the upper flange 10.
The resin upper ridge 10b has a vertical surface or a slightly inclined downward surface from the concave portion 10bc and an inversely tapered surface 10bd inclined to the multilayer glass 9 side. As a result, the condensed water overflowing the recess 10bc flows along the resin upper ridge 10b and flows down from the reverse tapered surface 10bd onto the multi-layer glass 9, so that it does not fall into the room.

1 and 3, a seal member 36A is installed on the outdoor side of the intermediate rail portion 15c of the metal upper frame 15 of the upper frame 2 as an airtight material that comes into contact with the upper arm 10 of the outer shroud 8. Is configured.
The intermediate resin frame 17 connected to the indoor side of the intermediate rail portion 15c has the same configuration as the upper resin angle 16 attached to the indoor side hanging piece 15d described above. That is, the intermediate resin frame 17 connected to the indoor side of the intermediate rail portion 15c also surrounds the indoor side and the front end by the tip piece 17a coming into contact with the lower end portion of the intermediate rail portion 15c. A heat insulating layer 42A having a substantially U-shaped cross section is formed by the tip piece 17a of the intermediate resin frame 17, the inclined stepped portion, and the fin portion 40A made of a soft resin, and the heat insulating layer 42A constitutes a heat insulating line.
In addition, in the resin upper collar 10b attached to the metal upper collar 10a of the external shoji 8, the indoor vertical section 10ba, the taper section 10bb, and the concave portion with which the fin section 40A abuts, similar to the resin upper collar 10b provided on the inner shoji 7, 10bc, a surface descending vertically or slightly inclined from the recess 10bc, and a reverse tapered surface 10bd.

Next, the lower resin angle 24 provided between the metal lower frame 19 and the frame 22 of the lower frame 3 will be described with reference to FIGS.
The lower resin angle 24 has substantially the same configuration as the upper resin angle 16 described above. The metal lower collar 11a forms a lower frame 11aa that extends and bends further to the lower side of the engaging portion with the resin lower collar 11b at the indoor side end. The indoor side wall surface 19a provided at the indoor side end portion of the metal lower frame 19 extends in the vertical direction, overlaps the lower frame 11aa in the horizontal direction at the upper end portion, and a receiving portion 19b is formed on the outdoor side. . An engagement receiving portion 19c is formed on the indoor side of the indoor side wall surface 19a.
A seal member 44 made of an elastic member such as an aluminum alloy or rubber fitted into the receiving portion 19b is in contact with the lower frame 11aa of the metal lower collar 11a, thereby preventing the cool air from flowing into the indoor side. Construct an airtight material.

A small gap K is formed between the indoor side wall surface 19 a of the metal lower frame 19 and the frame 22, and a lower resin angle 24 is installed on the upper portion thereof. The lower resin angle 24 is formed in a substantially flat plate shape, its base is fixed to the stepped portion of the frame 22 by a fixing bolt 45, and the tip is placed on the upper end of the indoor side wall surface 19a and has elasticity formed at the tip. A resin fin 46 is in contact with the lower frame 11aa provided on the metal lower frame 19.
The lower resin angle 24 is formed with a locking piece 48 (locking portion) that can be engaged with the engagement receiving portion 19c in the vicinity of the fin portion 46 in the vicinity of the fin portion 46 as a claw portion. On the 22 side, a contact piece 49 (contact portion) is formed which extends downward in the gap K and bends or curves on the tip side to contact the indoor side wall surface 19 a of the metal lower frame 19.

Therefore, the lower resin angle 24 is locked to the frame 22 and the metal lower frame 19 by the fixing bolt 45 and the locking piece 48. Moreover, since the locking piece 48 is provided on the indoor side of the indoor side wall surface 19a, when the fixing bolt 45 is removed from the frame 22 and the tip of the lower resin angle 24 on the fin portion 46 side is pulled up, the contact piece 49 is elastic. Since the latching piece 48 is disengaged from the engagement receiving portion 19c by deformation, it can be removed. Therefore, the lower resin angle 24 can be attached and detached.
Further, the upper resin angle 16 and the intermediate resin frame 17 described above also have the same configuration as the lower resin angle 24. That is, in the lower resin angle 24, when the tip piece 16c is pulled down, the contact piece 39 is elastically deformed, and the locking piece 38 is detached from the engagement receiving portion 37 and can be attached and detached. When the front end piece 17a is pulled down, the intermediate resin frame 17 can be exchanged by disengaging the engagement receiving portion provided on the base portion 15a.
Further, a seal made of an elastic member such as an aluminum alloy or rubber that fits into a receiving portion 19d formed on the metal lower frame 19 is provided at a contact portion between the metal lower collar 11a and the metal lower frame 19 of the external shoji 8. The member 44A is in contact with the metal lower collar 11a, and the seal member 44A constitutes an airtight material that prevents the cold air from being ventilated indoors.

The sliding window 1 according to the present embodiment has the above-described airtight and heat insulating structure, and its operation will be described next.
The sliding window 1 shown in FIGS. 1 and 2 is assumed to be installed in a building such as a middle floor or a high floor. In the closed state of the external door 8 and the internal door 7 of the sliding window 1, on the internal door 7 side, the low temperature outside air is generated by the intermediate rail portion 15 c of the upper frame 2 and the intermediate resin frame 17 and the upper arm 10 of the internal door 7. It flows in the space between and flows into the indoor side.
The outside air flows through the gap between the metal upper frame 15 on the indoor side and the upper collar 10 of the inner shoji 7 toward the indoor side hanging piece 15d side. Here, since the seal member 36 provided on the indoor side hanging piece portion 15d can be hermetically sealed by coming into contact with the metal upper collar 10a of the inner shoji 7, it prevents the outside air from flowing into the indoor side beyond the seal member 36. .

Further, a part of the outside air flowing between the indoor side hanging piece 15d and the upper lid 10 of the inner shoji 7 cools the indoor side hanging piece 15d and transmits the cold air downward. In this case, since the heat insulation layer 42 having a substantially U-shaped cross section is formed at the tip of the upper resin angle 16, low temperature transmission through the upper resin angle 16 and inflow of cold air to the indoor side are prevented. Or can be reduced.
Moreover, as shown in FIG. 3, the indoor side hanging piece 15d is surrounded by the outdoor side inner resin frame 18 and the indoor side upper resin angle 16 at the tip and both surfaces a1 and a2, so that the surface temperature is high and condensation occurs. Can be suppressed. Particularly, the tip and the indoor side of the indoor side hanging piece 15d exhibit a heat insulating effect because the heat insulating layer 42 and the contact piece 39 of the upper resin angle 16 cover the indoor side surface a1 of the indoor side hanging piece 15d. Thus, it is possible to suppress the transmission of cool air to the indoors and reduce the occurrence of condensation on the indoor side surface a1 of the indoor side hanging piece 15d.
However, some of the cool air wraps around the inner resin frame 18 and comes into contact with the indoor side hanging piece 15d, so that condensation may occur on the inner and outer surfaces a1 and a2 of the indoor side hanging piece 15d. Even in this case, the indoor side hanging piece 15d is covered with the contact piece 39 of the upper resin angle 16 and is not exposed to the indoor side, so that an indoor person cannot see.

Even if the surfaces a1 and a2 of the indoor side hanging piece 15d are condensed due to low temperature and a part of the condensed water flows as water droplets and flows downward, the fin 40 of the heat insulating layer 42 having a U-shaped cross section is used. The condensed water can be received and retained, and the falling of the condensed water can be suppressed.
Further, when the dew condensation water retained in the heat insulating layer 42 flows downward through the fin portion 40 due to its weight, a concave portion having a protrusion by flowing from the indoor vertical portion 10ba to the taper portion 10bb in the resin upper collar 10b. It is stored at 10bc. This also prevents the condensed water from falling indoors.
Furthermore, even if the condensed water overflows the concave portion 10bc, the condensed water does not fall on the floor surface or the like, and the multilayer glass 9 passes through the reverse tapered surface 10bd from the substantially vertical surface of the concave portion 10bc of the resin upper collar 10b. Flows down to the surface. Therefore, even if a part of the dew condensate flows downward from the resin upper wall 10b through the multi-layer glass 9 on the indoor side of the inner shoji 7, it is not noticeable.

  In addition, even when cold air enters between the outdoor-side hanging piece 15b of the metal upper frame 15 and the upper arm 10 of the outer shoji 8, heat insulation can be performed as in the case of the inner shoji 7. That is, the seal member 36 </ b> A abutted between the intermediate rail portion 15 c of the metal upper frame 15 provided on the indoor side of the external shoji 8 and the metal upper collar 10 a of the external shoji 8, An airtight line is formed between them. Therefore, the outside air is prevented from entering the indoor side by the seal member 36A.

Further, the intermediate resin frame 17 is covered with the tip piece 17a in contact with the tip of the intermediate rail portion 15c, and is provided with a heat insulating layer 42A having a substantially U-shaped cross section formed by the tip piece 17a and the fin portion 40A. Can be reduced or blocked.
Moreover, in addition to the heat insulating layer 42A, the surface on the indoor side of the intermediate rail portion 15c is surrounded by the intermediate resin frame 17, so that the surface temperature can be improved and condensation due to cold air can be prevented. Even if slight condensation occurs, it is not exposed to the indoor side and cannot be visually observed from the room because it is covered with the intermediate resin frame 17. When condensation occurs on the outdoor surface of the intermediate rail portion 15c, even if the condensed water falls, the condensed water can be stored in the heat insulating layer 42A, so that the fall can be prevented.
Further, even when a portion of the dew condensation water stored in the heat insulating layer 42A falls from the fin portion 40A, the dew condensation water that flows down can be similarly stored in the recess 10bc of the upper resin bowl 10b, and further along the multilayer glass 9 Can be washed away.
The upper resin angle 16 and the intermediate resin frame 17 are expanded and contracted by heat by locking the upper resin angle 16 to the indoor side hanging piece 15d and locking the intermediate resin frame 17 to the intermediate rail 15c. Can be suppressed.

4 to 6, even if the lower resin angle 24 is damaged or worn over time, it can be easily replaced. That is, when the fixing bolt 45 that fixes the lower resin angle 24 to the frame 22 is removed and the tip having the fin portion 46 is lifted upward, the tip of the contact piece 49 is in contact with the indoor side wall surface 19a, so that it is elastically deformed. To do. Then, the locking piece 48 is also deformed and detached from the engagement receiving portion 19c of the indoor side wall surface 19a, so that the lower resin angle 24 can be easily removed. Then, a new lower resin angle 24 may be attached by an operation reverse to the above operation and fixed to the frame 22 with the fixing bolt 45.
Similarly, with respect to the upper resin angle 16, similarly, the contact piece 39 may be elastically deformed by pulling the tip piece 16 c to remove the locking piece 38 from the engagement receiving portion 37.

1 and 4, on the indoor side of the inner rail 21, the seal member 44 provided on the indoor side wall surface 19a of the metal lower frame 19 is in contact with the metal lower collar 11a of the inner shroud 7 to keep it airtight. ing. And the fin part 46 of the lower resin angle 24 is also contact | abutted to the metal lower collar 11a, and is hold | maintained in the airtight state. In addition, on the indoor side of the outer rail 20, the seal member 44 </ b> A provided on the receiving portion 19 d of the metal lower frame 19 is in contact with the metal lower collar 11 a of the outer shoji 8 and is kept airtight.
Therefore, even if rainwater or the like is sprayed on the sliding window 1, there is little rainwater drained by the outdoor side wall surface 11 c in the metal lower frame 19 of the inner shoji 7 or the outer shoji 8 and flowing into the indoor side. In addition, since the sealing members 44 and 44A of the inner shoji 7 and the outer shoji 8 are installed on the inner side of the inner rail 21 and the outer rail 20, rainwater passes through the sealing members 44 and 44A due to the differential pressure between the external pressure and the inner atmospheric pressure. Can be prevented from entering the indoor side.

As described above, according to the sliding window 1 according to the present embodiment, the lower resin angle 24 of the lower frame 3 and the upper resin angle 16 of the upper frame 2 are located on the indoor side of the indoor side wall surface 19a and the indoor side hanging piece 15d. Since the locking pieces 48 and 38 and the contact pieces 49 and 39 are provided, it is possible to easily remove and attach them by elastically deforming them by peeling off the outdoor end. Moreover, a heat insulating layer can be formed by the contact pieces 49 and 39, between the locking pieces 48 and 38, and between the indoor side wall surface 19a and the indoor side hanging piece 15d.
In the lower frame 3, the metal lower frames 19 of the inner and outer children 7 and 8 are provided with the sealing members 44 and 44 </ b> A on the inner side of the inner rail 21 and the outer rail 20. In addition, rainwater or the like blown into the lower frame 3 can be prevented from entering the indoor side due to a pressure difference between the inside and outside.

  The sliding window 1 according to the present invention is not limited to the above-described embodiment, and can be appropriately changed or replaced without departing from the gist of the present invention. Other embodiments and modifications of the present invention will be described below, but the same or similar parts and members as those described in the above-described embodiments will be described using the same reference numerals.

In the embodiment described above, the contact pieces 49 and 39 of the lower resin angle 24 and the upper resin angle 16 are extended until they contact the indoor side wall piece 19a of the metal lower frame 19 and the indoor side hanging piece 15d of the metal upper frame 15. Although formed, it may be non-contact as long as it extends long so as to cover the locking pieces 38 and 48 to ensure heat insulation. Even in this case, when the lower resin angle 24 and the upper resin angle 16 are elastically deformed, the contact pieces 49 and 39 contact the indoor side wall surface 19a and the indoor side hanging piece 15d of the metal upper frame 15.
Further, although the lower resin angle 24 and the indoor side wall surface 19a and the upper resin angle 16 and the indoor side hanging piece 15d are provided with the locking pieces 48 and 38 and the engagement receiving portions 19c and 37, respectively, the locking pieces 48 and 38 are provided. And the arrangement of the engagement receiving portions 19c and 37 may be reversed.
