Description

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

Conventionally, in the fittings, the following two types are known as an angle structure for connecting the frame body to the frame body such as a frame.
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 having an L-shaped cross section and made of an aluminum alloy extruded shape member 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. Then, the cover member is placed on the upper surface of the other mounting piece of the angle member and fitted and hidden between the upper end of the frame and the frame.

An angle 104 made of resin is installed in a staircase shape between the rail 103 for running.
The angle 104 has one end screwed on the frame 102, and both ends of the lower stage of the angle 104 are fixed by being locked to two locking portions of the indoor side wall surface of the lower frame 101 and the root of the rail 103. is doing.
Moreover, the seal member 105 provided on the lower frame of the inner shoji 106 is set outside the rail 103, and the tip thereof abuts on the rail 103 to hermetically seal.

Japanese Patent No. 4871570

  However, in the angle of the sash frame described in Patent Document 1 described above, even if the angle is cracked or damaged after installation, one mounting piece inserted in the gap is screwed to the frame body. I couldn't remove it.

  In addition, since the angle 104 of the latter sash frame is fixed at both ends of the lower stage of the angle 104 by the two locking portions of the indoor side wall surface of the lower frame 101 and the root of the rail 103, the locking is performed after mounting. It was difficult to remove the part. Therefore, if 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.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a fitting capable of easily attaching and detaching an angle.

The fitting according to the present invention includes a frame body for housing a shoji screen, and an angle provided in a gap formed between the frame body and an indoor member, and the frame body and the angle are provided in the gap. The locking portion and the engagement receiving portion provided on the other side are arranged so as to be engaged with each other.
ADVANTAGE OF THE INVENTION According to this invention, an angle is installed on the space | gap between a frame and an indoor side member, and an angle is provided by engaging the engagement part and engagement part provided in the frame and an angle in a space | gap. In addition to being able to be attached to the frame, the engaging portion and the engagement receiving portion can be disengaged and removed by pulling the angle.
The angle may be either a resin angle or a metal angle, but if a resin angle is used, the thermal conductivity can be reduced and dew condensation can be reduced.

Further, it is preferable that an elastically deformable abutting portion that extends into the gap and abuts against the frame body or the indoor member is provided on the indoor side in the prospective direction of the locking portion or the engagement receiving portion formed in the angle.
The angle fixed to the frame body is provided with an abutting portion abutting against the wall surface of the frame body or the indoor side member in the prospective direction indoor side separately from the locking portion or the engagement receiving portion engaged with the frame body. Therefore, the abutting portion can enhance the heat insulating property. Moreover, when the angle is removed, if the angle on the frame body side is pulled away, the abutting part is elastically deformed and the locking part and the engagement receiving part can be separated, so removal is easy, and even if the angle is damaged It 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 on the angle.
By providing the resin angle, the heat insulating layer can be formed and the dew condensation can be reduced.

Further, fins may be provided at the outdoor end of the angle.
As a result, airtightness can be improved by bringing the fin portion provided on the angle into contact with the shoji screen.
Further, one of the frame and the shoji may be provided with an airtight member that comes into contact with the other, so that the airtightness can be improved in, for example, a building.

  In the fitting according to the present invention, the angle can be fixed to the frame body by engaging the locking portion and the engagement receiving portion of the frame body and the angle within the gap between the frame body and the member on the indoor side. Since the interlocking portion is located in the space on the indoor side of the frame, the engagement between the locking portion and the engagement receiving portion can be disengaged and removed by pulling the angle. Therefore, it is easy to attach and detach the angle to and from the frame body.

The inner shoji 7 and the outer shoji 8 are formed in a rectangular frame shape with an upper frame 10, a lower frame 11, and left and right vertical frames 12, 13 respectively, and a multi-layer glass 9 such as paired glass is housed therein. ..
In FIGS. 1 and 3, the upper frame 2 of the frame body 5 is mainly formed of a metal upper frame 15, and an upper resin angle 16 made of resin is connected to the surface on the indoor side thereof. The metal upper frame 15 has an outdoor side hanging piece 15b hanging from the outdoor side end, an intermediate rail part 15c hanging from the middle part, and an indoor side hanging from the indoor side end as viewed from the prospective direction of the base part 15a forming the upper surface part. It has the hanging piece part 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 abutted on the outdoor side surface of the indoor side hanging piece portion 15d. There is. Moreover, the intermediate resin frame 17 and the inner resin frame 18 are connected by the resin connecting plate 14 and engaged with the base portion 15a. The indoor side hanging piece 15d made of metal is surrounded by the inner resin frame 18 and the upper resin angle 16 to surround the indoor and outdoor surfaces a1 and a2.
The shoji screen 8 is movably held between the outdoor side hanging piece portion 15b and the intermediate rail portion 15c. The inner shoji 7 is movably held between the intermediate rail portion 15c and the indoor side hanging piece portion 15d.
Further, in FIGS. 1 and 4, the lower frame 3 is mainly formed by the metal lower frame 19, the outer rail 20 is formed in the outdoor side region when viewed in the prospective direction of the metal lower frame 19, and the indoor side region is formed. The inner rail 21 is formed. A door roller (not shown) of the outer shoji 8 is movably mounted on the outer rail 20, and a door roller of the inner shoji 7 is movably mounted on the inner rail 21 to receive the loads of the outer shoji 8 and the inner shoji 7, respectively. ing. A lower resin angle 24 made of resin and having a substantially L-shaped cross section is detachably installed at an indoor end of the metal lower frame 19 between the metal lower frame 19 and a wooden frame 22 shown in FIG.

In addition, in FIG. 2, the left and right vertical frames 4 are mainly formed by metal vertical frames 25, and a resin vertical frame 26 having a plurality of hollow portions is connected to the indoor side of the left metal vertical frame 25, and the right vertical metal frame 25 is connected. A side resin angle 27 having the same structure as the upper resin angle 16 is connected to the inside of the frame 25.
Further, in the external shoji 8 and the internal shoji 7, the frame portions on the four sides of the multi-layer glass 9 are composed of an upper frame 10, a lower frame 11, and left and right vertical frames 12, 13. The multi-layered glass 9 is supported at its four side edges by glass receiving portions 34 provided on the upper metal frame 10a, the lower metal frame 11a, and the left and right metal vertical frames 12a and 13a via glazing channels. The indoor side of these metal frames is covered with a resin upper frame 10b, a resin lower frame 11b, and left and right resin vertical frames 12b and 13b, respectively.
The metal upper frame 15, the metal lower frame 19, the left and right metal vertical frames 25, the metal upper frame 10a, the metal lower frame 11a, and the left and right metal vertical frames 12a, 13a are made of, for example, an aluminum alloy.

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

Further, the resin upper resin angle 16 engaged with the indoor side hanging piece portion 15d of the upper metal frame 15 has a main body portion 16b having a stepped portion 16a, and the tip piece 16c thereof is the indoor side hanging piece. The lower end of the portion 15d is abutted and covered.
Further, the upper resin angle 16 has a locking piece that can be engaged with the engagement receiving portion 37 by having the base portion contact the indoor-side hanging piece portion 15d near the tip end side near the stepped portion 16a and bend the tip end side 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 tip side so as to surround the locking piece 38 and abuts on the indoor side hanging piece portion 15d (abutting portion 39). ) Is formed.
In addition, a fin portion 40 made of a soft resin that extends toward the upper frame 10 on the outdoor side, that is, the inner shoji 7, is connected or integrally formed at a corner of the stepped portion 16a. The soft resin of the fin 40 is softer and elastically deformable than the other resins, and is in contact with the upper frame 10 of the inner shoji 7.
When the inner shoji 7 is moved, the fins 40 are displaced in contact with each other and maintain an airtight state.
The fin portion 40 may be formed of a relatively hard resin like other resins, and in this case, it is preferable that the fin portion 40 is brought into contact with the upper frame 10 of the inner shoji 7 in a non-contact manner in order to maintain airtightness. ..

On the other hand, on the upper frame 10 of the inner shoji 7, the indoor side end of the upper metal frame 10a has, for example, a vertically extending surface portion 10aa that abuts the sealing member 36 of the upper resin angle 16 to hermetically seal it. The seal member 36 and the surface portion 10aa form an airtight line that blocks ventilation of outside air into the room.
Further, the resin upper frame 10b, which is connected to the metal upper frame 10a on the indoor side, forms an indoor-side vertical portion 10ba in which the portion with which the fin portion 40 abuts is, for example, flat. Further, a taper portion 10bb which is inclined so as to widen toward the indoor side is formed in a lower portion thereof, and a concave portion 10bc having a projection portion at a tip thereof is further formed in a lower portion thereof.
The resin upper frame 10b may be formed of a soft resin so as not to come into contact with the upper frame 2 and be damaged when the inner sliding door 7 is removed from the frame body 5 to the indoor side.

Therefore, the stepped portion 16a of the upper resin angle 16, the tip piece 16c, and the fin portion 40 form a heat insulating layer 42 having a substantially U-shaped cross section for heat insulating the cold air transmitted from the outdoor side to form a heat insulating line. To do. Further, even when the dew condensation attached to the surfaces a1 and a2 of the indoor side hanging piece portion 15d drops along the surfaces a1 and a2, it can be held by the heat insulating layer 42. Further, even if the condensed water flows from the heat insulating layer 42 through the soft fin portion 40 to the resin upper frame 10b, it can be stored in the concave portion 10bc. In the heat insulating layer 42, the tip piece 16c is in non-contact with the upper frame 10 and the fin portion 40 is in contact therewith, but the fin portion 40 may be in non-contact as long as it extends to a position close to the upper frame 10.
Further, the resin upper frame 10b has a vertical surface or a surface that slightly descends from the recess 10bc and a reverse taper surface 10bd that slopes toward the double glazing 9 side. As a result, the dew condensation water that overflows the recess 10bc flows along the resin upper frame 10b and flows down from the reverse taper surface 10bd onto the double glazing 9, and therefore does not fall into the room.

1 and 3, a seal member 36A is installed as an airtight material that abuts the upper frame 10 of the shoji 8 on the outdoor side of the intermediate rail portion 15c of the metal upper frame 15 of the upper frame 2 as well. Is composed of.
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 portion 15d described above. In other words, the intermediate resin frame 17 connected to the indoor side of the intermediate rail portion 15c also surrounds the indoor side and the distal end by the tip piece 17a contacting the lower end portion of the intermediate rail portion 15c. The tip piece 17a of the intermediate resin frame 17, the inclined step portion, and the fin portion 40A made of soft resin form a heat insulating layer 42A having a substantially U-shaped cross section, and the heat insulating layer 42A constitutes a heat insulating line.
Further, in the resin upper frame 10b attached to the metal upper frame 10a of the outer shoji 8, like the resin upper frame 10b provided on the inner shoji 7, the indoor side vertical part 10ba, the taper part 10bb, and the recessed part with which the fins 40A abut. 10 bc, a surface that descends vertically or slightly inclined from the recess 10 bc and an inverse taper surface 10 bd.

Next, the lower resin angle 24 provided between the metal lower frame 19 of the lower frame 3 and the frame 22 will be described with reference to FIGS. 4 to 6.
The lower resin angle 24 has substantially the same structure as the upper resin angle 16 described above.
The metal lower frame 11a forms a lower frame 11aa that extends further below the engaging portion with the resin lower frame 11b at the indoor end and bends. The indoor side wall surface 19a provided at the indoor side end of the metal lower frame 19 extends in the vertical direction, overlaps the lower frame 11aa in the horizontal direction at the upper end, and the receiving portion 19b is formed on the outdoor side thereof. .. An engagement receiving portion 19c is formed on the indoor side wall surface 19a on the indoor side.
The seal member 44, which is made of an elastic material such as aluminum alloy or rubber, and which fits into the receiving portion 19b, is in contact with the lower frame 11aa of the lower metal frame 11a, and prevents ventilation of cool air to the indoor side. It constitutes an airtight material.

Further, a small gap K is formed between the indoor side wall surface 19a 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, the base thereof is fixed to the step portion of the frame 22 by a fixing bolt 45, and the tip end is placed on the upper end of the indoor side wall surface 19a and has the elasticity formed at the tip end. The fin part 46 made of resin is in contact with the lower frame 11aa provided on the metal lower frame 19.
On the lower resin angle 24, a locking piece 48 (locking portion) that can be engaged with the engagement receiving portion 19c downward in the gap K near the fin portion 46 is formed as a claw portion, and the frame thereof is further formed. On the 22 side, an abutting piece 49 (abutting portion) is formed which extends downward in the gap K and bends or curves at the tip side to abut the indoor side wall surface 19a 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. As the locking piece 48 is disengaged from the engagement receiving portion 19c by being deformed, it can be removed. Therefore, the lower resin angle 24 is removable and replaceable.
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 disengaged from the engagement receiving portion 37 so that it can be detached and replaced. With respect to the intermediate resin frame 17, when the tip piece 17a is pulled down, the engagement receiving portion and the engagement portion provided on the base portion 15a are disengaged and can be replaced.
In addition, a seal made of an elastic member made of aluminum alloy or rubber, which is fitted to the receiving portion 19d formed on the metal lower frame 19, is provided at a contact portion between the metal lower frame 11a of the outer shoji 8 and the metal lower frame 19. The member 44A is in contact with the lower metal frame 11a, and the sealing member 44A constitutes an airtight member that blocks the ventilation of cool air to the indoor side.

The sliding window 1 according to the present embodiment has the above-described airtight and heat insulating structure, and its operation will be described below.
It is assumed that the sliding window 1 shown in FIGS. 1 and 2 is installed in a building such as a middle floor or a high floor. In the closed state of the sliding door 8 of the sliding window 1 and the sliding door 7 on the inner sliding door 7 side, low temperature outside air causes the middle rail portion 15c of the upper frame 2 and the intermediate resin frame 17 and the upper frame 10 of the inner sliding door 7. It flows through the space between and flows into the indoor side.
Then, the outside air flows toward the indoor side hanging piece portion 15d side through the gap between the indoor upper metal frame 15 and the upper frame 10 of the inner sliding door 7. Here, since the seal member 36 provided on the indoor-side hanging piece 15d abuts on the metal upper frame 10a of the inner shoji 7 to perform an air-tight seal, the outside air is prevented from flowing over the seal member 36 to the indoor side. ..

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

Then, even if the surfaces a1 and a2 of the indoor side hanging piece 15d are condensed due to the low temperature and a part of the condensed water becomes water drops and flows downward, the fins 40 of the heat insulating layer 42 having a U-shaped cross section. 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 fins 40 due to its weight, the resin upper frame 10b flows from the indoor-side vertical portion 10ba through the taper portion 10bb to form a concave portion having a protrusion. It is stored at 10 bc. This also makes it possible to prevent the condensed water from falling on the indoor side.
Further, even if the dew condensation water overflows the recess 10bc, the dew condensation water does not drop to the floor surface or the like, and the double-sided glass 9 passes from the substantially vertical surface of the recess 10bc of the resin upper frame 10b through the reverse taper surface 10bd. Run off to the surface. Therefore, even if a part of the condensed water flows downward from the resin upper frame 10b through the double glazing 9 on the indoor side of the inner sliding door 7, it is not conspicuous.

  Further, even when cold air enters between the outdoor side hanging piece 15b of the metal upper frame 15 and the upper frame 10 of the outer shoji 8, the heat can be insulated as in the case of the inner shoji 7. That is, with the sealing member 36A abutting between the intermediate rail portion 15c of the upper metal frame 15 provided on the indoor side of the outer shoji 8 and the upper metal frame 10a of the outer shoji 8, the upper frame 10 of the inner shoji 7 and Form an airtight line between. Therefore, the outside air is prevented from entering the indoor side by the seal member 36A.

Further, since the tip 17a of the intermediate resin frame 17 abuts against the tip of the intermediate rail portion 15c to cover it, and the tip 17a and the fin portion 40A are provided with a heat insulating layer 42A having a substantially U-shaped cross section, the inside side of the outside air is closed. Can be reduced or prevented.
Moreover, since the indoor side surface of the intermediate rail portion 15c is surrounded by the intermediate resin frame 17 in addition to the heat insulating layer 42A, the surface temperature can be improved and dew condensation due to cold air can be prevented. Even if a slight amount of dew condensation occurs, since it is covered with the intermediate resin frame 17, it is not exposed to the indoor side and cannot be visually observed from the room. When dew condensation occurs on the outdoor side surface of the intermediate rail portion 15c, even if the dew condensation water drops, the dew condensation water can be stored in the heat insulating layer 42A, so that the fall can be prevented.
Moreover, even when a part of the condensed water stored in the heat insulating layer 42A drops from the fin portion 40A, the condensed water that flows down can be stored in the concave portion 10bc of the resin upper frame 10b, and further along the double glazing 9. Can be washed away.
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, it is possible to prevent the upper resin angle 16 and the intermediate resin frame 17 from expanding and contracting due to heat. Can be suppressed.

Further, in FIGS. 4 to 6, even when the lower resin angle 24 is damaged or worn over time, it can be easily replaced. That is, when the fixing bolt 45 for fixing 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, and thus elastically deformed. To do. Then, the locking piece 48 is also deformed and disengaged 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 the reverse operation to the above operation and fixed to the frame 22 with the fixing bolt 45.
Similarly, with respect to the upper resin angle 16, the abutting piece 39 may be elastically deformed by pulling the tip piece 16c, and the locking piece 38 may be removed from the engagement receiving portion 37.

In FIGS. 1 and 4, on the indoor side of the inner rail 21, a sealing member 44 provided on the indoor side wall surface 19a of the metal lower frame 19 is brought into contact with the metal lower frame 11a of the inner shoji 7 to maintain the airtight state. ing. The fin portion 46 of the lower resin angle 24 is also in contact with the lower metal frame 11a and is kept airtight. Further, on the indoor side of the outer rail 20, the seal member 44A provided on the receiving portion 19d of the metal lower frame 19 is in contact with the metal lower frame 11a of the outer shoji 8 and is kept airtight.
Therefore, even if rainwater or the like is sprayed on the sliding window 1, little rainwater flows into the indoor side after being drained by the outdoor side wall surface 11c of the metal lower frame 19 of the inner shoji 7 or the outer shoji 8. In addition, since the seal members 44 and 44A for the inner shoji 7 and the outer shoji 8 are installed on the indoor side of the inner rail 21 and the outer rail 20, rainwater passes through the seal members 44 and 44A due to the pressure difference between the outer pressure and the inner pressure. Can be prevented from flowing indoors.

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 provided on the indoor side wall surface 19a and the indoor side hanging piece portion 15d on the indoor side. Since the locking pieces 48, 38 and the contact pieces 49, 39 are provided, the tip on the outdoor side can be peeled off to elastically deform and easily removed and attached. Moreover, the abutting pieces 49, 39 can form a heat insulating layer between the locking pieces 48, 38 and between the indoor side wall surface 19a and the indoor side hanging piece portion 15d.
Further, in the lower frame 3, since the metal lower frames 19 of the inner shoji 7 and the outer shoji 8 are provided with the seal members 44 and 44A on the inner side of the inner rail 21 and the outer rail 20, they are in the middle and high floors of a high-rise building. Also, it is possible to prevent rainwater and the like blown into the lower frame 3 from entering the indoor side due to the 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 scope of the present invention. Hereinafter, other embodiments and modified examples of the present invention will be described, but the same or similar parts or members as those described in the above-described embodiments will be denoted by the same reference numerals and description thereof will be omitted.

In the embodiment described above, the contact pieces 49, 39 of the lower resin angle 24 and the upper resin angle 16 are extended until they come into contact with the indoor side wall surface 19a of the metal lower frame 19 and the indoor side hanging piece portion 15d of the metal upper frame 15.
