Description

  The present invention relates to an opening device provided with a plurality of shojis arranged inside and outside and movable in the left-right direction in a frame body and provided with a smoke return structure.

  As one of the opening devices of this type, a frame composed of an upper frame, a lower frame, and left and right vertical frames provided around the opening of a building, and a shoji provided in the frame so as to be movable in the left-right direction. There is also known a full-open sash (full-open sash) that is provided with a door pocket that houses the shoji in a retractable manner and that can fully open the opening (see, for example, Patent Document 1).

In such a fully open sash, for example, the opening of a window or the like can be fully opened, so that not only the convenience is improved, but when the window is opened, the shoji can not be seen from the indoor side, thereby improving the design. Can be planned.
Here, generally, in the sliding window sash having the inner and outer shoji, a crescent lock is usually provided. The crescent lock is, for example, a hook provided on the side panel panel (glass) side of the outside shoji (outer shoji) summoning side, and the left side of the summit side of the inside shoji (inner shoji) summoning side or It consists of a rotatable semi-disc with a handle, provided on the end face facing right. This semi-disc has a protrusion, and the semi-disk is rotated so that the protrusion is hooked on the hook and tightened in the left-right direction and the front-rear direction so as not to open the window.
When this crescent tablet is used, the crescent tablet protrudes from the shovel of the shoji to the glass side as described above, thereby disturbing the vertical line of the chisel and lowering the design.

JP-A-6-26286

  By the way, if a door lock (including a joint lock) is used without using a crescent lock, for example, the design of the summoned portion can be improved. The door is not fastened and fixed like a lock, so even if it is locked with a door lock, the door is locked due to the clearance between the sash frame and the door, between the door and the door, or due to errors within the allowable range. There is a possibility of rattling. In other words, when the door lock is used, the shoji is rattled by vibrations caused by wind or passing of a car.

  In addition, in the fully open sash, in order to facilitate the opening operation of the shoji, for example, it extends up and down to the interior side of the downspout on the summit side of the shoji and the outboard side of the downspout on the summit side of the shoji. It is conceivable to provide a smoke hook having a cross-sectional hook shape that has a folded piece. Accordingly, when the external shoji is moved out of the door pocket and moved to the close side, and the external shoji is substantially out of the door pocket, the smoke return of the external shoji and the smoke return of the internal obstruction are engaged. Furthermore, by moving the external shoji to the closing side, the internal shoji is pulled by the external shoji via smoke return, and the internal shoji is closed in conjunction with the external shoji. Therefore, it is preferable to provide a smoke return in the fully opened sash in which the shoji is stored in the door pocket when opened in consideration of convenience when closing the shoji. In addition, when you close the door lock (or joint lock) of the shingles by providing smoke traps on the vertical saddle on the door pocket side of the shingles placed on the door pocket side when closing, and the vertical, The inner scotch is engaged with both the smoke squeezing of the outer sward and the vertical smoke squeezing so that it cannot move to the left and right, and the inner sward is locked with the opening closed.

However, when the smoke return is provided, if the door is locked in place of the crescent lock as described above, the paper sho At that time, smoke folds made of, for example, aluminum (alloy) of the external shoji and the internal shoji come into contact with each other, and an unpleasant metal sound is generated. That is, as described above, the inner shroud that is restricted from moving to the left and right by the smoke return of the external shoji and the vertical smoke return can be moved slightly to the left and right by the clearance between the smoke return. Yes, this causes rattling.
In this case, for example, it is conceivable to provide a sub-lock that tightens the external reflex child and the reflex child at the summoning part of the external reflex child and the internal reflex child, but if the sub-block is not used, stop rattling. I can't.

Further, if the clearance between the smoke smokes engaged when closing is set to 0 and the smoke smokes are brought into contact with each other when closed, it is possible to prevent the generation of metallic noise and further the occurrence of rattling itself. it can. However, dimensional variations due to manufacturing errors and the like occur, and even if the clearance is designed as 0, there is a possibility that the clearance will occur. On the other hand, there may be a case where the clearance becomes negative and the shoji cannot be closed smoothly.
In addition, when a metal sound based on rattling is generated even when the wind blows, the sash is used when accustomed to a crescent lock that does not rattle. There is a risk of misunderstanding that is not locked.

  The present invention has been made in view of such circumstances, and when using smoke return and not using a crescent lock, the shoji of the shoji at the time of locking and the shakiness of this shoji The purpose is to prevent the generation of noise due to smoke return.

In order to achieve the above object, an opening device according to claim 1 is provided with a frame body and a movable body in the left-right direction in the frame body, and at least a part of the opening device is front and rear in the indoor side and the outdoor side. With a plurality of shojis arranged at different positions,
The inside of the frame body is partitioned into an opening and a shoji storage portion with a border arranged in the vertical direction as a boundary,
In the state where the opening is closed by the shoji, the left and right edges adjacent to the front and rear are adjacent so that the left and right edges of the other shoji out of the left and right edges of the shoji overlap. Smoke return that engages with each other between the left and right side edges is provided,
The side of the shoji on the vertical side is further closed from the predetermined position in a state in which the shoji on the vertical side that is arranged on the most side when the opening of the shoji is closed is arranged at a predetermined position. A restricting member for restricting movement to
The regulating member is
Among the shojis that can be interlocked in the closing direction of the shoji on the vertical side based on the engagement of the smoke return, at least the shoji that is farthest from the stand in the closed state is moved to the open side. When locked to prohibit,
The predetermined position can be adjusted to be the position of the standing-side shoji where the mutually engaged smoke chimes come into contact with each other in the pair of smoke chimes that engage with each other in a series of interlocking shojis. It is characterized by becoming.

The invention according to claim 2 is the opening device according to claim 1, wherein the frame body is formed in a rectangular frame shape from an upper frame, a lower frame, and left and right vertical frames,
The regulating member is fixed to the upper frame or the lower frame,
An abutting portion that abuts on an upper end portion or a lower end portion of a summing-side end surface that is the opposite side of the vertical side shoji is provided,
And the position of the said contact part can be adjusted to right and left, It is characterized by the above-mentioned.

In the opening device, the shoji is basically arranged in a sliding manner, but it may be a double-slip type (drawing type) shoji in which a plurality of shojis on the left and right are arranged in the drawing. It may be a single-draw type where the shojis are arranged in a sliding manner, and there may be two or three or more shojis that are linked and connected by smoke return. It is only necessary that the smoke stacks respectively provided on the left and right side edges of the shoji that overlap in the front and rear direction so that the positions in the left and right directions coincide with each other in the closed state are engaged with each other.
Smoke return is well known and is connected to each other when moving the shoji in the closing direction, and is disconnected when moving the shoji in the opening direction.

Further, in the case of the single pull type, one stand is arranged in the frame body, and one side in the left-right direction is an opening portion with this stand as a boundary, and the other side is a shoji storage portion (door pocket). Further, in the case of the double-alignment type, verticals are arranged on the left and right sides of the frame body, and the left and right end sides of the frame body are used as the shoji storage portions, and the central side is the opening portion, with the vertical frame as a boundary. .
In addition, in the structure of the above-mentioned this invention, it describes on the basis of one stand, and in the case of a double opening type, two sets of structures described except a frame will exist.
In addition, the shoji to be locked is locked on the frame body side in a state of being fixed by a door lock, for example, and the position is fixed, but in the case of a double opening device, a joint lock may be used. In addition, the object to be locked is not fixed, and the positions are fixed to each other by locking. However, if the predetermined position of the regulating member is accurately adjusted, movement to the open side is prohibited. It becomes a state.

  According to the opening device of claim 1, when the shoji on the side farthest from the stand is fixed by the door lock or the joint lock without using the crescent lock, the shoji on the stand side is in a predetermined position. When the movement in the direction away from the vertical is regulated by the regulating member, and the movement of the shoji on the vertical side is regulated at a predetermined position, the smoke folds engaged with each other are in contact with each other. In this case, the movement of the shoji farthest from the vertical to the vertical (open side) is restricted by locking, and the vertical shoji closest to the vertical moves to the side away from the vertical (closed side). In a restricted state, the smoke return is in contact with each other, that is, the clearance is 0, so that the back of the shoji is prevented and the back of the smoke is separated or bumped by the play of the shoji. This prevents the generation of metallic sounds.

In addition, it is also possible to provide a smoke return that engages with each other on the vertical and vertical side shojis, and these smoke return can also regulate the movement of the vertical side shoji away from the side, but in this case It is necessary to design and manufacture the opening device with the clearance between the smoke stacks being zero so that the smoke stacks that are engaged with each other with the shoji closed are in contact with each other as described above. It is practically impossible to set the clearance to 0 for all products, and the rattling cannot be eliminated for all products. On the other hand, in the present invention, instead of this vertical smoke return, the above-mentioned regulating member regulates the movement of the vertical side shoji and is manufactured by adjusting the regulating position to be a predetermined position. It is possible to prevent rattling and abnormal noise caused by all products.
In the present invention, there may or may not be a vertical smoke return. When there is a vertical smoke return, the vertical smoke return and the shoji side smoke return engaged with the smoke return are not basically in contact with each other. The position of the shoji is not restricted by the vertical smoke return, but the position is restricted by a restriction member that is a member different from the vertical smoke return.

According to the opening device of claim 2, the regulating member is attached to the upper frame or the lower frame of the frame body, and the abutment portion comes into contact with the end face of the vertical side shoji to move the vertical side shoji. The position where the movement is restricted can be adjusted to a predetermined position by shifting the position of the contact portion to the left and right.
Thus, for example, when closing the shoji that is farthest from the shoji connected by smoke return when it is closed, the door is locked so that the shoji on the vertical side is pressed against the erect side. If the position of the part is determined, the smoke smokers that engage with each other in the locked state (not including the vertical smoke smoker and the smoke smoker that engages this vertical smoke smoker) will be in contact with each other. It can be in contact. In this case, the regulating member can be adjusted from the indoor side. Then, the regulating member can be easily adjusted by simply fixing the contact portion at the position determined in this way. In addition, the adjustment method of a control member is not restricted to this.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
FIGS. 1-8 is a figure which shows the sash of the two-piece single-drawing full opening type which concerns on embodiment of this invention, Comprising: FIG. 1 is a cross-sectional view of a closed state, FIG. FIG. 3 is a longitudinal sectional view showing an upper frame cover, FIGS. 4 to 5 are drawings showing a regulating member described later, and FIGS. 7 and 8 are manufactured later. It is drawing for demonstrating the response | compatibility method to an error.

  This sash (opening device) is a sash of a single pulling full opening type (single pulling type) in which two shojis are arranged so as to be pulled in and out as shown in FIGS. This sash is arranged in the frame A attached to the opening of the building, and the frame A is shifted in the front-rear direction to the indoor side and the outdoor side, and is movable in the left-right direction (horizontal direction). The external shoji (shoji) B and the internal shoji (shoji) C provided in the 1, 7, and 8, illustrations of the panel fitted into the shoji B and C and the upper frame 1 of the frame A are omitted, and are on the right side of a later-described vertical E of the frame A. Only a part of the shoji storage portion D is shown (the vertical frame 4 on the right side of the frame A (the shoji storage portion D side) is not shown).

  The side of one side (in this example, the right side) of the frame A is provided with a shoji storage section (also referred to as a door pocket section) D that can store the shoji B and C. It is partitioned from the opening F of the sash by the vertical E. In this sash, the opening F can be fully opened by storing the outer shoji B and the inner shoji C in the right shoji housing portion D. That is, in FIG. 1, the external obstacle B and the internal obstacle C can be moved to the right side of the screen E. The opening F is arranged so as to substantially overlap with the opening of the building, and the opening formed in the building can be almost fully opened. As shown in FIGS. 2 and 3, the screen doors M and N are arranged so as to be separated from each other on the outside of the paper frame B and C of the frame A, and the screen doors M and N are also on the side of the paper screen storage portion D. The opening F can be brought into a fully open state by being drawn into the position.

The frame A is constructed by being assembled into a rectangular frame shape by an upper frame 1, a lower frame 2, and left and right vertical frames 3, 4. 1, 7, and 8, the cross section is shown as viewed from the bottom to the top, but the upper frame 1 and the upper frame cover 50 described later are not shown. Yes.
The external shoji B is constructed by assembling a rectangular frame-shaped cage assembly with the upper cage 11, the lower cage 12, and the left and right vertical rods 13, 14, and the laminated glass 16 as a panel is incorporated in the cage assembly. ing. In addition, the inner shoji C is constructed by assembling a square cage assembly with the upper cage 21, the lower cage 22 and the left and right vertical rods 23, 24, and incorporating the double-glazed glass 26 as a panel into the cage assembly. ing.
The upper collars 11 and 21, the lower collars 12 and 22, and the left and right vertical collars 13, 23, 14, and 24 are made of a metal such as an aluminum alloy, and the indoor side of the multilayer glass 26. And the surface exposed to the indoor side is covered with a resin cover as a resin shape member of a heat insulating sash having a composite structure, and the above-mentioned metal portion Is not exposed to the indoor side. That is, the outer shoji B and the inner shoji C have a heat insulating sash shoji B, C having a composite structure in which the exterior side is exposed from a metal such as an aluminum alloy or its painted surface, and the interior side is covered with a resin cover made of synthetic resin. It has become.

As shown in FIG. 2, the rail 1 a for the handicapped child B and the rail 1 b for the handicapped child C are formed in a rib shape on the lower surface, which is the inner side surface of the upper frame 1 of the frame A. Rails 1a and 1b are respectively inserted into the upper arm 11 of the outer shoji B and the upper arm 21 of the inner shoji C, and are locked to the rails 1a and 1b so as to be movable left and right along the length direction thereof. The rail latching | locking part 11a, 21a to be performed is provided.
At this time, a space is provided between the lower surface of the upper frame 1 and the upper surface of the upper collar 11 of the outer obstacle B and the upper collar 21 of the inner obstacle C.

The lower arm 12 of the external shoji B and the lower arm 22 of the inner shoji C are equipped with wheels 12a and 22a that facilitate the movement of the outer shoji B and the inner shoji C, and the lower arm 12 and 22 Are formed with latching ribs 12b, 22b extending downward from the wheels 12a, 22a.
In addition, on the upper surface, which is the inner side surface of the lower frame 2 of the frame A, the positions through which the wheels 12a and 22a of the above-mentioned obstacles B and C are slightly sticking out, but there is no clear rail. On the upper surface of the lower frame 2 of the frame A, slits extending in the left and right directions, in which the locking ribs 12b and 22b are movably inserted in the left and right directions, are formed. The shoji C cannot be removed. This frame A is used for a sweep-out window in which the upper surface of the lower frame 2 is substantially equal to the floor level, and is a barrier-free type in which there are almost no steps such as rails on the upper surface of the lower frame 2.

In addition, as a two-sheet single-drawing sash, the outer shoji B substantially contacts the opposite side of the shoji storage portion D of the frame A, that is, the left vertical frame 3 when the opening F is closed. Arranged on the left side, the inner shoji C is arranged on the right side of the opening F on the side of the shoji storage portion D.
Further, as shown in FIG. 1, a soot smoke 18 is formed on the interior side of the downspout 14 serving as the summoning side of the external shoji B, and the downspout 23 serving as the summoning side of the internal shunt C described later. It engages with the smoke return 28 formed on the outdoor side surface. Then, when the external shoji B is moved to the side where the opening F is closed, the smoke return 18 of the external shoji B is engaged with the smoke return 28 of the internal shoji C on the way, and the internal shoji is interlocked with the external shoji B. C moves to the closing side. Further, when the external obstacle B is moved to the side where the opening F is opened, the engagement between the smoke return 18 of the external obstacle B and the smoke return 28 of the internal obstacle C is released.

The above-described smoke return 28 is formed on the outdoor side surface of the vertical rod 23 on the calling side of the inner shoji C.
As described above, with the opening F closed by the shoji B and C, the left and right edges of the other shoji among the left and right edges of the shoji B and C (vertical rods 13, 14, 23 and 24). The right and left side edges (vertical rods 14, 23) of the shoji that are adjacent to each other so that the left and right positions overlap with each other are smoke smokers 18, 28 that engage with each other between the adjacent left and right edges. Each is provided.

  Further, a smoke return 29 that engages with a smoke return 31 of a vertical E to be described later is formed on the indoor side surface of the vertical fence 24 on the door end side (the shoji storage portion D side) of the inner shoji C. As a result, the shoji C is pulled out from the shoji storage portion D, and the vertical fence 24 on the shoji storage portion D side of the shoji C and the vertical E overlap in the indoor-outdoor direction, and the smoke return 29 and the smoke return 31 are engaged. When the smoke return 29 and the smoke return 31 come into contact with each other, it becomes impossible to move further away from the shoji storage portion D. In this example, however, when the shoji C is moved in a direction away from the shoji storage portion D, before the smoke return 29 and the smoke return 31 come into contact with each other, the restricting member 40 described later is brought into contact with the inner shuffle C. Thus, the end face of the vertical rod 23 comes into contact with each other, whereby the movement of the inner cuff C is restricted, so that the smoke return 29 and the smoke return 31 do not come into contact with each other.

  Therefore, the smoke return 31 of the vertical E and the smoke return 29 provided on the door-end side spatula 24 of the inner couch C that engages with the smoke return 31 are in a state in which the outer obstacle B and the inner obstacle C are closed. , It does not prevent the inner shoji C from moving further away from the vertical E and prevent the vertical F side of the opening F from opening (the restricting member 40 prevents). It becomes for improving the airtightness of E and the vertical gutter 24 of the inner cuff C. In this case, for example, a seal member made of an elastic member such as rubber or soft synthetic resin is provided so as to extend from the vertical E to the longitudinal cage 24 side of the inner couch C and extend vertically. The smoke return 29 and the smoke return 31 may be omitted as long as the airtightness of the vertical hoist 24 can be secured.

  These smoke return 18, 28, 29, 31 are basically formed in a shape (hook shape) whose cross section is bent at a right angle and extends over the top and bottom of the shoji B, C. When the smoke smokes 18 and 28 (29, 31) to be engaged are engaged with each other so as to hook each other and moved in the engaged state in the engaged state, the smoke smoke 18 and 28 ( 29, 31) come into contact with each other and cannot move in the direction of relatively further engagement.

The stand E extending vertically is provided between the opening F of the frame A and the shoji storage portion D. The vertical E has an upper end joined to the upper frame and a lower end joined to the lower frame 2. Further, the side of the shoji storage portion D from the side E of the frame A is outside the opening of the building and is invisible from the indoor side by the wall. Further, the smoke return 31 described above is provided on the outdoor side surface of the vertical E.
On the other hand, the opening F is in a state where its inner peripheral portion is exposed from the indoor side by the opening of the building. The periphery of the rectangular opening F is composed of the upper frame of the frame A on the upper side, the lower frame 2 of the frame A on the lower side, the vertical frame 3 of the frame A on the left side, and the vertical E on the right side. Yes.
An angle 33 that forms a rectangular cylindrical inner peripheral surface is attached to the inner peripheral surface side of the opening F composed of the upper frame, the lower frame 2, the vertical frame 3, and the vertical E. 33 is the resin structure of the above-mentioned composite structure of the heat insulating sash, and is formed from a synthetic resin.

FIG. 1 shows a state in which the summit 14 on the summoning side of the external shoji B and the summit 23 on the summoning side of the inner shrimp C are overlapped with the left and right positions being substantially the same. This is basically a state in which the door F provided on the door side of the handicap B can be locked or in a locked state with the opening F closed by the handicapped B and the handicapped C. It is shown.
As shown in FIG. 6, the smoke return 28 provided on the vertical hook 23 on the summoning side of the inner shoji C is formed to extend vertically along the longitudinal direction of the outdoor side surface of the vertical hook 23, In addition, a base piece 28a provided along the plane direction of the inner cuff C and in the left-right direction, a bent piece 28b that bends and projects outward from the base piece 28a at a right angle, and a base piece 28a from the bent piece 28b. And a folded piece 28c folded back to the shoji storage portion D side.

Accordingly, the folded piece 28c extends to the shoji storage portion D side along the left-right direction.
The base piece 28a and the bent piece 28b also serve as members constituting the main body of the vertical rod 24.
Further, in the inner shroud C, the outdoor side surface of the main body of the vertical shaft 24 and the outdoor side surface of the folded piece 28c are arranged in one plane along the left-right direction. Further, a groove-like concave portion extending vertically is formed between the folded piece 28c and the base piece 28a so as to open to the side of the shoji storage portion D (the door tip side of the inner shoji C).

  The smoke return 18 provided on the vertical fence 14 on the summoning side of the shoji B is formed so as to extend vertically along the longitudinal direction of the indoor side surface of the chisel 14, and the surface direction of the external shoji B And a base piece 18a provided along the left and right direction, a bent piece 18b protruding from the base piece 18a at a right angle toward the indoor side, and a door to be parallel to the base piece 18a from the bent piece 18b. And a folded piece 18c folded back to the side. The bent piece 18b is located on the side of the shoji storage portion D from the tip of the above-described folded piece 28c of the longitudinal hook 23 of the inner sward C, and slightly more indoor than the folded piece 28c from the indoor side surface of the longitudinal collar 14 of the outer sward B. Protruding.

  Then, in a state where the smoke smokers 18 and 28 are engaged with each other, the folded piece 18c extends from the distal end portion of the bent piece 18b along the base piece 18a to the base piece 28a and the folded piece 28c. It is in the state inserted between. Note that the base piece 18a and the bent piece 18b of the smoke return 18 also serve as members constituting the main body of the vertical rod 14.

  A buffer member 60 made of, for example, rubber (including rubber-like synthetic resin) or soft synthetic resin is attached to the inner side surface (the surface facing the door end side) of the bent piece 18b. The cushioning member 60 has a thickness (the clearance at the time of design) expected for the smoke return 18 of the external obstacle B and the smoke return 28 of the internal obstacle C in a state in which the thickness of the external obstacle B and the internal obstacle C is closed and locked. It is almost the same. Here, the clearance between the smoke return 18 and the smoke return 19 is, for example, the distance between the bent piece 18b of the smoke return 18 and the tip of the folded piece 28c of the smoke return 28, or the bent of the smoke return 28. This is the distance between the piece 28 b and the tip of the folded piece 18 c of the smoke return 18. Moreover, although the buffer member 60 extends up and down substantially the same as the vertical width of the external obstacle B, it does not necessarily need to be one and may be divided into a plurality of upper and lower parts. There may be a vertical gap between them.

With this buffer member 60, the clearance between the smoke return 18 and the smoke return 28 is practically zero at the time of design.
In addition, the movement of the inner shoji C to the left and right is restricted by the engagement of the smoke return 29 provided on the vertical fence 24 on the door end side and the vertical smoke return 31. A clearance similar to that between the smoke stack 18 and the smoke stack 28 is sometimes set between the smoke stack 29 and the smoke stack 31. The movement to the left and right is restricted by the locked external obstacle B, and the movement can be made to the left and right by the clearance.

  That is, even if the clearance between the smoke return 18 and the smoke return 28 is practically zero by the buffer member 60, the smoke return 29 on the door-end side of the shoji C and the smoke return 31 of the vertical E are provided. Therefore, when the outer obstacle B is locked and fixed, the inner obstacle C can be moved to the left and right by the clearance between the smoke return 29 and the smoke return 31. In other words, when the external obstacle B and the internal obstacle C are closed and the external obstacle B is locked, the buffer member 60 attached to the bent piece 18b of the smoke return 18 of the external obstacle B and the internal obstacle C are summed. When the tip of the folded piece 28c of the smoke return 28 on the side comes into contact, the space between the smoke return 29 on the door tip side of the inner couch C and the smoke return 31 of the vertical E is spaced by the designed clearance. As a result, the movement of the inner cuff C to the side of the outer baffle B, which is locked by this interval, is restricted by a regulating member 40 described later. Even if a clearance is set between the smoke smokes 18 and 28 and between the smoke smokes 29 and 31, it cannot move left and right.

  Further, a door lock (not shown) is provided on the vertical hook 13 on the door tip side of the external shoji B so that the vertical hook 13 can be fixed to the vertical frame 3 of the frame A. The door lock can be locked even at a position (within a preset allowable range) where the end face of the door B on the side of the door B is slightly away from the position closest to the vertical frame 3 of the frame A. Due to the manufacturing error, as described later, it is regulated by the engagement (contact) of the regulating member 40, the smoke smoke 18 and the smoke smoke 28, and the end face on the door end side of the outer panel B is the most of the frame A. Locking is possible even in a state in which the shoji B cannot be moved to a position approaching the vertical frame 3.

  Further, as shown in FIG. 1, when the frame A is closed, airtight ribs 3a are formed on the side surface of the vertical frame 3 that opposes the door end side end surface of the outer panel B to extend vertically. An airtight holding member 13a that secures airtightness when the outer obstacle B is closed by engaging with the airtight rib 3a is formed on the door end side vertical rod 13 of B. The airtight rib 3a has a margin in the length in the left-right direction, and maintains airtightness even when the door end side face of the outer panel B cannot move to the position closest to the vertical frame 3 of the frame A as described above. The member 13a can be engaged. That is, if the door lock can be basically locked, the airtightness between the frame body A and the closed outer panel B can be secured by the airtight holding member 13a.

Next, the regulating member 40 according to the present invention will be described.
As shown in FIGS. 4A and 4B, the restricting member 40 is detachably attached to the lower surface, which is the inner surface of the upper frame 1, in this example. The regulating member 40 is made of, for example, aluminum (alloy) formed by extrusion molding.
And the regulation member 40 is the state attached to the upper frame 1, between the rail 1a with which the outer obstacle B is movably latched on the outer side rather than the upper collar 21 of the inner obstacle C, and the inner obstacle C The attachment part 41 arrange | positioned and the contact part 42 arrange | positioned inside the attachment part 41 in the position which overlaps with the movement path | route to the right and left of the upper arm 21 of the inner couch C are provided.

  The lower surface of the mounting portion 41 is higher than the upper collars 11 and 21 of the external obstacle B and the internal obstacle C, and does not interfere with the external obstacle B and the internal obstacle C. On the other hand, the lower surface of the contact portion 42 is lower than the upper surfaces of the upper collars 11 and 21. And since the contact part 42 is arrange | positioned in the position which overlaps with the movement path | route to the left and right of the upper arm 21 of the inner couch C as mentioned above, it contacts the upper arm 21 of the inner arm and the direction of the inner arm C The movement in the direction away from the stand E (the shoji storage portion D) (the closing direction) is restricted.

  The mounting portion 41 and the contact portion 42 are integrally molded, and the lower surface of the mounting portion 41 and the contact portion 42 are lower than the mounting portion 41 as described above. A step is formed at the boundary with 42. Further, on the lower surface of the regulating member 40, a plurality of steps corresponding to a portion (left side) opposite to the side E of the regulating member 40 and an upper frame cover 50 provided on a portion inside the regulating member 40. Is provided and is designed to be unified with the upper frame cover 50 in design.

  Here, the upper frame cover 50 has an angle that forms the inner peripheral surface of the opening F on the lower surface of the upper frame on the indoor side of the inner frame C when the opening F is closed by the outer panel B and the inner frame C. It arrange | positions in the position which becomes between 33 and the external shoji B. In other words, the upper frame cover 50 is disposed at a position overlapping the closed external obstacle B in the inner and outer directions. This is because when the external shoji B and the internal shoji C are closed, on the inner shoji C side, the resin-made angle 33 and the resin cover on the indoor side of the internal shoji C are arranged with almost no space between them. If the end portion on the indoor side of the angle 33 is located on the inner side from the inner impingement C, there will be a large gap between the angle 33 and the resin cover on the inner side of the outer obstacle B. Therefore, the angle 33 is filled to fill this portion. The upper frame cover 50 in a continuous state is arranged to improve the design.

  Further, the left and right attachment ranges of the upper frame cover 50 and the attachment positions of the restricting member 40 are overlapped, and as shown in FIG. 4A, the right end portion of the upper frame cover 50 (the side of the shoji storage portion D side). A notch 51 is formed on the outdoor side of the end) corresponding to the attachment position of the regulating member 40. Then, the restriction member 40 is attached to the upper frame 1 at the notch 51. Therefore, the upper frame cover 50 is disposed on the indoor side from the regulating member 40. In addition, almost half of the upper frame cover 50 on the indoor side has a height substantially equal to the height of the lower surface of the contact portion 42 of the restricting member 40 (the upper ends of the shojis B and C so as to hide the upper end of the shoji B. The lower half of the upper frame cover 50 has a base portion 53 whose lower surface is higher than the upper end of the external obstacle B so as not to interfere with the external obstacle B. .

The restricting member 40 is located on the outdoor side of the cutout portion 51 of the upper frame cover 50, and the lower surfaces of the contact portion 42 and the protruding portion 52 of the restricting member 40 are substantially the same height. Thereby, the restricting member 40 and the upper frame cover 50 have a substantially integrated shape, and the design property is prevented from being lowered due to the restricting member 40 being conspicuous.
2 and 3 are cross sections on the left side of the restriction member 40, and the restriction member 40 is hidden by the upper frame cover 50.

The mounting portion 41 of the restricting member 40 is formed with screw holes 44 and 44 for screwing at two locations on the left and right sides in the central portion in the inner and outer direction that is formed by the contact portion 42. As will be described later, the screw holes 44, 44 are elongated holes that are long to the left and right so that the position of the restricting member 40 (abutment portion 42) can be adjusted by shifting to the left and right.
The upper frame 1 of the frame A is formed with screw holes that are screwed into the screws 45 and 45 inserted through the screw holes 44 and 44 in correspondence with the attachment positions of the restricting members 40.

And as shown in FIG. 1, the attachment position of the restricting member 40 is the state which closed the door block of the external obstacle B and closed the door pad of the external obstacle B, and the internal obstacle C contact | abutted the restricting member 40. Thus, the tip of the folded piece 28c of the smoke return 28 of the inner couch C is in contact with the buffer member 60 of the smoke return 18 of the external obstacle B. In other words, in the state where the door block of the external obstacle B and the internal obstacle C are closed and the door lock of the external obstacle B is locked, the tip of the folded piece 28c of the smoke return 28 of the internal obstacle C is placed on the buffer member of the smoke return 18 of the external obstacle B. And the contact side end face of the inner shoji C and the contact face of the restricting member 40 facing the shoji storage portion D come into contact.
The position of the inner limb C in this state is a predetermined position of the inner limb C regulated by the regulating member 40.

  In this case, the external shoji B is fixed in a state in which it cannot move to the left and right by locking the door lock, and the internal shoji C is fixed to the tip of the folded piece 28c of the smoke return 28 in the vertical rod 23 on the calling side. The movement to the right (in the direction toward the shoji storage portion D) is restricted by contacting the buffer member 60 attached to the smoke return 18 of the shoji B in a state where the door is fixed. The side end surface (the end surface of the vertical rod 23) comes into contact with the contact surface of the restricting member 40, and movement in the left direction (the direction toward the external obstacle) is restricted. As a result, the inner limb C is in a state in which it cannot move to the left or right, and has no backlash.

Then, the external shoji B and the internal shoji C do not rattle from side to side, and the smoke return 18 of the external shoji B and the smoke return 28 of the internal shoji C are brought into contact with each other via the buffer member 60. Therefore, the generation of the metallic sound caused by the smoke smoke 18 and the smoke smoke 28 colliding with each other is completely eliminated.
In addition, the smoke return 31 of the vertical E and the smoke return 29 on the door side of the inner limb C are in a state where movement of the inner limb C to the left and right is restricted in a state where the clearance is opened, The engaged smoke return 31 and the smoke return 29 do not come into contact with each other, and generation of a metallic sound between the smoke return 31 and the smoke return 29 is also prevented.

Here, the above description has been given of the case where the clearance between the smoke stack 18 and the smoke stack 28 and the clearance between the smoke stack 29 and the smoke stack 31 are as designed values. Will increase or decrease.
For example, when the lateral width of the frame is slightly wider than the design value, or when the smoke fold 18 and the smoke fold 28 are in contact with each other via the cushioning member 60, the outer limb B and the inner limb C are combined. When the left and right width is slightly narrower than the design value, the clearance is increased. Conversely, when the left and right width of the frame is slightly narrower than the design value, the smoke return 18 and the smoke return 28 are buffered. When the left and right width of the outer obstacle B and the inner obstacle C in a state of being in contact with each other via the member 60 is slightly wider than the design value, the clearance is narrowed.

Here, when the right and left positions of the restricting member 40 (abutting portion 42) are determined according to the design value, if the clearance becomes wide due to a manufacturing error or the like, the summing side end face of the inner limb C is contacted with the restricting member 40. In the state of being in contact with the contact surface, a gap is generated between the cushioning member 60 attached to the smoke return 18 of the outer obstacle B and the tip of the folded piece 28c of the smoke return 28 of the inner obstacle C. As a result, in the state where the external shoji B is locked with the door lock, the internal shroud C can move slightly to the left and right in accordance with the amount of deviation from the design value.
Therefore, by shifting the position of the regulating member 40 (contact portion 42) so as to approach the side of the shoji storage portion D (shifting away from the vertical frame 3), the tip of the folded piece 28c of the smoke return 28 of the inner shoji C. Can be brought into contact with the buffer member 60 attached to the smoke return 18 of the external shoji B. In other words, in a state in which the shoji B is locked, the position of the regulating member 40 is shifted until the tip of the folded piece 28c of the smoke stack 28 of the shoji C comes into contact with the buffer member 60 attached to the smoke stack 18 of the shoji B. By fixing the restricting member 40 to the upper frame 1 again, it is possible to prevent rattling even when the clearance between the smoke smokes 18, 28, 29 and 31 is widened due to a manufacturing error within an allowable range.

  That is, the restricting member 40 is the most in the closed state among the shojis that can be interlocked in the closing direction of the inner shoji C on the side E based on the engagement of the smoke smokers 18 and 28. When the distant shoji B is locked so as to prohibit at least the movement to the open side, the predetermined position is set in the pair of smoke smokers 18 and 28 of the interlocking shoji B and C that are engaged with each other. The position can be adjusted so that the position of the inner limb C on the side E where the engaged smoke smokes 18 and 28 come into contact with each other.

  On the other hand, when there is an error that the clearance between the smoke return 18, 28, 29, 31 becomes narrow, the state shown in the figure is obtained. That is, when the external obstacle B and the internal obstacle C are closed, the end face on the door-end side of the external obstacle B is slightly separated from the vertical frame 3 of the frame A from the normal position. In this case, the well-known door lock has an adjustment function for an error, and can be locked even if it is slightly away from the vertical frame 3. By adjusting the door lock, the design value described above can be obtained. The same effect as when there is no deviation can be obtained. As described above, when the opening F is closed, the airtight material that secures the airtightness between the vertical frame 3 of the frame A and the vertical rod 13 on the door-end side of the outer panel B is also allowable in the horizontal direction. If the position shift due to the above-described error of the external obstacle B is within an allowable range, airtightness can be ensured.

  In the above case, the amount of deviation from the design value needs to be within an allowable range expected in advance. If the allowable range is exceeded, the movement of the restricting member 40 (contact portion 42) and the adjustment of the door lock cannot be handled, and rattling cannot be completely prevented, or locking of the door lock becomes difficult. Or a gap may be formed between the vertical frame 3 of the frame A and the external shoji B. Further, when the restricting member 40 can be moved to the left and right, if the left and right widths of the frame A and the shojis B and C are substantially equal to the design value, the restricting member 40 (abuts on the substantially central portion of the left and right moving range). Part 42) is arranged, and as described above, the restricting member 40 is set to either the left or right regardless of whether the left and right widths of the shojis B and C are short or long with respect to the left and right width of the frame A due to manufacturing errors or the like. It may be possible to respond by moving.

In the above example, the present invention is applied to a two-seat single-drawn full-open type sash, but the present invention can also be applied to other types of sashes. It can be applied to a full opening type sash. In this case, the configuration of the above example may be basically applied to each of the left and right shojis except that the door lock is a joint lock. Further, the present invention can be applied to a sash having three or more sheets on one side and five or more sheets on both sides.
In this case, when the door is closed, the shoji placed on the vertical E side (here, the innermost shoji) becomes the shoji that the regulating member 40 regulates.

Further, the sash is not necessarily limited to the fully open type that is completely opened, and may have a structure in which a part of the shoji remains in the opening when opened.
Further, the attachment position of the regulating member 40 is not limited to the upper frame 1, and may be attached to the lower frame 2. In addition, when the sash is of a sweeping window as in the above example and the upper surface of the lower frame 2 has a structure without protrusions (rails, etc.) because it is barrier-free, it can be attached to the upper frame 1. preferable.

  Further, the restricting member 40 can restrict the movement (movement toward the closing side) of the inner impingement C, which is arranged closest to the standing E side when closed, from the side E (the shoji storage portion D). And the structure will not be limited if it does not regulate the movement to the open side of the shoji C to which the movement is restricted without restricting the movement of other shoji.

The shock-absorbing member 60 is attached to the bent piece 18b of the smoke return 18 of the outer obstacle B, and the tip of the folded piece 28c of the smoke return 28 of the inner shroud C is brought into contact with the buffer member 60. The buffer member 60 may be attached to the bent piece 28b of the return 28, and the tip of the folded piece 18c of the smoke return 18 of the external obstacle B may be in contact with the buffer member 60.
In addition, the left and right screw holes for fixing the regulating member 40 to the upper frame 1 are long holes on the left and right sides. The screw hole for screw may be formed in the restricting member 40, or a long hole is formed in the upper frame 1, the male screw is fixed to the restricting member 40, and the nut is screwed to the male screw and fixed. It is good also as what to do.

  Note that the adjustment of the predetermined position where the movement of the inner impingement C in the opening direction by the restriction member 40 is restricted is not limited to the above-described one. The adjustment member may be detachable, and may be adjusted according to the thickness (width in the left-right direction) and the number of adjustment members disposed between the regulating member 40 and the summing-side end surface of the inner impingement C, for example, You may arrange | position the adjustment member which can adjust protrusion length from the control member 40 with a screw etc., for example.

  Further, when the shock-absorbing member 60 is not provided and the smoke return 18 of the external obstacle B and the smoke return 28 of the internal impediment C contact each other, the bent piece 18b of the smoke return 18 (the bent piece 28b of the smoke return 28) and the smoke You may make it the front-end | tip of the return piece 28c of the return 28 (the front-end | tip of the return piece 18c of the smoke return 18) contact | abut directly. In addition, it is preferable that the buffer member 60 is provided in terms of durability and reliable prevention of the generation of metal sound. In addition, when the buffer member 60 is not used, the clearance between the smoke return 18 of the external obstacle B and the smoke return 28 of the internal impact child C may be set to 0 by design, and the clearance does not become 0 due to a manufacturing error. In this case, it can be dealt with by adjusting the position of the regulating member 40 (contact portion 42) as described above.
