Abstract

A sliding door or window has a sliding door or window (B), which is positioned on the internal side of a fixed door or window (F) when open and which closes an open section (R) when closed, in a coplanar position. The sliding door is supported, with the aid of sliding door support pieces, by a pair of pulleys, which travel along the upper guide rails (19) so as to change the position of the sliding door in the direction of the pulleys. A bend space (30) is provided close to a door front edge of the upper guide rails. One end of the bend space communicates with a guide space which is provided between the guide rails (19), whereas the other end of the bend space is arranged on the external side of the guide space. The front edge side of the sliding door is supported, with the aid of arm pieces, by an upper guide member, which travels through these spaces so as to change the position of the sliding door in the direction of the upper guide member. <IMAGE>

Description

k -. SINGLE SLIDING SASH The present invention relates to' a single

sliding sash in which a sliding door which is positioned on the internal side of a fixed section when open and which closes an open section when closed is fixed to a window frame which has the fixed section on one side thereof and the open section on the other side.

While it is needless to cite well-known examples, conventional single sliding sashes are constructed in such a manner that when open sections of window frames are closed iby sliding doors, the sliding doors are positioned outside fixed sections. The outward appearance of such a conventional single sliding sash is similar to that of the so-called horizontally sliding sash.

According to conventional examples, since the sliding door is arranged close to the fixed section on the internal side when the door is closed, the outward appearance of such a sash is not good as compared with the so-called fixed sash. The outward appearance of an entire building is spoiled, especially when a fixed sash as well as a single sliding sash are fixed to the building, because the outward appearances of both the types of sashes differ from each other.

An object of the present invention is to provide a single sliding sash whose outward appearance is similar to that of a fixed sash when the door is c1osed.

In order to achieve this object, a sliding door, supported by sash pulleys which travel along guide rails, travels in the direction of an open section. A guide member, provided on the front edge of the sliding door, travels through a guide space, and further into a bend space, thereby shifting from the internal side of a fixed section to the external side of the fixed section. At this time, when the sliding door is pressed in the direction of the sash pulleys and an upper guide member, the position of the sliding door changes from the opening position to the external direction.

As a result, the sliding door is positioned flush with the fixed section. The sliding door is supported not only by the sash pulleys with the aid of sliding door support pieces, but also by the upper guide member with the aid of arm pieces. An object of the present invention is to provide a novel single sliding sash. An exemplary embodiment is now described with reference to the accompanying drawings, wherein:- Fig. 1 is a schematic illustration showing the state where various sections of a single sliding sash according to the present invention are arranged; C Fig. 2 is a cross-section view taken along line 1A-1A of Fig. 1; Fig.

As illustrated in the drawings, a single sliding sash of the present invention has a construction in which a sliding 18 is a cross-sectional view taken along line 1F1-1H s a cross-sectional view taken along line 19; s a cross-sectional view taken along line 19; a cross-sectional view taken along line 1J-1J -5door B is attached to a window frame A having a fixed section F on one side of the frame A. (Refer to Fig. 1, which shows the state where various components of the-single sliding sash are arranged, so that it is easy to understand the sash by contrasting Fig. 1 with the other drjawings.) As shown in Figs. 2 and 3, the window frame A is constructed in the following manner. A head 1, a sill 2, a door front edge hard frame 3 (illustrated on the right side of Fig. 2; hereinafter referred to simply as a door edge hard frame 3), a door rear edge hard frame 31 (illustrated on the left side of Fig. 2; hereinafter referred to simply as a door edge hard frame 3'), and a mullion 4 are fixed together. A glass panel 5 is then fitted into a space composed of the head 1, the sill 2, the door edge hard frame 31 in order to provide the fixed section F. An open section R which is opened and closed by the sliding door B is provided adjacent to the fixed section F.

The open section R of the window frame A is composed of an exterior piece la of the head 1, an exterior piece 2a of the sill 2, an exterior piece 3a of the door edge hard frame 3, and one side 4al of an exterior piece 4a of the mullion 4. First attachment grooves 6, 61, 611, 6111 are provided on the ends of all the exterior pieces la, 2a, 3a, 4a. That is, the grooves are provided on the side face of an internal piece of the open section R. A first air- and water-tight material 7 is attached to the first attachment grooves so as to cover -6the open section R mentioned above. The end 71 of the first air- and water-tight material 7 is directed in the internal direction so as to protrude from the first attachment grooves 6, 6f, 611, 6111 (see Figs. 2 and 19).

As illustrated in Figs. 2 and 3, the fixed section F is constructed in the following way. The glass panel 5 is engaged with the exterior piece la of the head, and the exterior piece 2a of the sill 2. The glass panel 5 is also engaged with an exterior piece 31a of the door edge hard frame 31, and the other side 4all of the exterior piece 4a of the mullion 4. The glass panel 5 is also engaged with an engaging groove 9 which is composed of battens 8, 81, 811. The battens 8, 81, 811 are attached to all of the head 1, the door edge hard frame 31, and the mullion 4. The glass panel 5 is then clamped by a dry air- and water-tight material 10 arranged on the external side, a wet air- and water-tight material 101, and by a relatively hard spacer material 1011. Both of the materials 101 and 1011 are arranged on the internal side. This hard spacer material 10 serves as a backup material for the wet air- and water-tight material 101.

Also, as shown in Fig. 2, a cross-sectional first step 11a as well as a cross-sectional second step 11b are provided on the side of the open section R of the mullion 4 so as to gradually draw toward the side of the fixed section F 1 1 -7 mentioned above. A second attachment groove 12111 is provided on the first stage lla. The second attachment groove 12111 communicates with second attachment grooves 12, 121, 1211 which are all provided on the first stage of the head 1, which will be described later. A pai, of vertical L-shaped intermediate drawing pieces 13, 131 are fixed to the inner face 41 of the mullion 4, which is positioned between the second step 11b and the internal edge of the mullion 4.

As shown in Figs. 2 and 17, the mullion 4 is fixed, with the aid of L-shaped attaching pieces 14, to the head 1 and the sill 2.

Moreover, as illustrated in Figs. 2 and 3, receiving pieces lb, 2b, 3b, are attached to the sides of the exterior pieces la, 2a, 3a. The ends of the receiving pieces lb, 2b, 3b are positioned outside the exterior pieces la, 2a, 3a of the head 1, sill 2, and the door edge hard frame 3, respectively. That is, the pieces are positioned on the outside of the window frame A. The second attachment grooves 12, 12.9 1211 are provided on the internal side of the receiving pieces lb, 2b, and 3b. The second attachment grooves 12, 121, 1211 communicate with the second attachment groove 12111, which is provided on the firs-IC step lla of the mullion 4. Second air- and water-tight materials 15 are provided to the second attachment grooves 12, 121, 1211, 12111 so that the ends 151 thereof protrude in theinternal ( i direction.

The above-mentioned sliding door B is constructed by fixing together an upper rail 16, a lower rail 17, meeting stiles 18, a hard rail 181, and a glass panel 51 (see Figs. 2 and 19). In the same manner as with the glass panel 5 of the fixed section F, the glass panel 51 is clamped by the dry air- and water-tight material 10 arranged on the external side, the wet air- and water-tight material 101 arranged on the internal side, and by the relatively hard spacer material 1011. This spacer _material 1011 serves as a backup material for the wet air- and water-tight material 101.

As shown in Figs. 2 and 19, when the sliding door is being closed, all of the ends of the exterior pieces 16a, 17a, 18a, 18 'a of all the rails 16, 17, 18, 181 are arranged so that the ends do not protrude in the direction of the open section R from the exterior pieces and one side 4al of the exterior piece 4a of the mullion 4. These exterior pieces are la of the head 1, 2a of the sill 2, and 3a of the door edge hard f rame 3. When the sliding door is being closed, the meeting stiles 18 is constructed so as to be stored in the mullion 4; that is, within the width of the exterior piece 4a.

The sliding door B is constructed in the following manner. A sash pulley 20 on the side of a meeting style which travels along upper guide rails 19 on the head 1, a sash pulley 21 on the front edge of the door, and an upper guide member 22, are attached to the upper rail 16. A lower guide member 24 on the side of the meeting style which travels along lower guide rails 23 on the sill 2, and a lower guide member 25 on the front edge of the door are attached to the above-mentioned lower rail 17. When the sliding door B is being opened, it is constructed so as to be overlapped by the fixed section F as a result of the travel of the sash pulleys 20, 21, and the guide members 22, 24, 25. When the sliding door B is being closed, it is constructed so as to close the open section R, and is positioned parallel to and flush with the fixed section F.

As illustrated for instance in Fig. 3, 14 or 23, the upper guide rails 19 mentioned above are made of horizontal pieces which are formed by bending the lower ends of the exterior piece lc of the head 1 and of an intermediate piece 1d arranged between the exterior piece lc and the receiving piece 1d so as to be opposite one another. The end of the intermediate piece 1d forming these"upper guide rails 19, and the end of the horizontal piece of the exterior piece lc on the side of the door edge hard frame 3, are cut away 27. An upper auxiliary block 28 is fitted into the cut-away section 27, and is fastened to the head 1 mentioned above by means of screws 29 (see Figs. 22 and 23). One end of a bend space 30, which is provided on the upper auxiliary block 28, 1 corresponds to a guide space 26 formed by the upper guide rails 19, 19, whereas the other end of the bend space 30 is arranged adjacent to the exterior piece lL of the head 1.

In other words, the upper guide rails 19 are arranged parallel to the above-mentioned fixed section F on the internal. The guide space 26 between the upper guide rails 19, 19 communicates with the bend space 30 formed by the upper auxiliary block 28. The above-described sash pulleys 20, 21 travel along the upper guide rails 19, 19. On the other hand, the upper guide member 22 is engaged with the guide space 26 and the bend space 30 so as to travel along these spaces 26, 30.

As illustrated for example in Figs. 14, 16, 22 and 24, the lower guide rails 23 are composed of an interior piece 2c of the sill 2, and a first intermediate piece 2d adjacent to the interior piece 2c. In the same manner as with the upper guide rails 19, the lower guide rails 23 are arranged parallel to the fixed section F on the internal side. A doorway cut-away section 33 is provided at the center of the first intermediate piece 2d which forms the lower guide rails 23, that is, in the part where the mullion 4 and the meeting stiles 18 are overlapped. A groove 32 along which travels a first roller 24a of the lower guide member 24 on the side of the meeting style, is provided in the doorway cut-away section 33. The groove 32 is composed of the first intermediate piece 2d of the sill 2, and a second intermediate piece 2e disposed outside the first intermediate piece 2d (see Figs. 14 and 16). Furthermore, as shown in Fig. 24, the ends of the first and second intermediate pieces 2d, 2e on the side of the above-mentioned door edge hard frame 3 are cut away 271 A lower auxiliary block 281 is fitted to the cut-away section 271 so that it is positioned directly under the upper auxiliary block 28. The lower auxiliary block 281 is then fastened to the sill 2 by means of the screws 29. One end of a bend rail 34, which is provided on the lower auxiliary block 281, corresponds to the above-mentioned lower guide rail 23. An open end 341 on the other end of the bend rail 34 is positioned adjacent to the receiving piece 2b of the sill 2 arranged outside the second intermediate piece 2e mentioned above. The open end 341 communicates, through the space 35 between the lower auxiliary block 28' and the receiving piece 2b, with a drainage hole 36 which is provided on the receiving piece 2b.

On the one hand, the lower guide member 24 on the side of the meeting style, and the lower guide member 25 on the front edge of the door are arranged so as to travel along the On the other hand, the lower guide edge of the door is arranged s.o as to rails 34 which communicate with the lower guide rails 23.

member 25 on the front travel along the bend lower guide rails 23.

1 -12 The drainage hole 36 communicates with the outside via a drain opening 37 which is disposed on the lower end of the external side of the sill 2.

The sash pulley 20 (see Figs. 11, 12 and 15) on the side of the meeting style is constructed in the following manner.

It is rotatably fixed to one end of a main frame 39 on the side of the meeting stiles 18, to which an upward drawing roller 40, which also serves as a lock, is rotatably fixed.

Wheels 20a, which roll along the upper guide rails 19, are rotatably fixed by axles 38 to the main frame 39. The base end side of a sliding door support piece 41 is rotatably fixed by a support shaft 42 to the intermediate section of the main frame 39. A coiled spring 43 is additionally provided between the support shaft 42 and the upward drawing roller 40 mentioned above. A first stopper 44, energized in a rising direction, is fixed so as to rise and fall. Also, a support piece 45 is arranged on one end of the main frame 39 on the f ront edge of the door so as to be suspended through the guide space 26 mentioned above. A roller 46 is rotatably fixed to the support piece 45, and is engaged with a first arc-like groove 47 which is arranged in the intermediate section of the sliding door support piece 41. A second stopper 49, suspended from the main frame 39 between the support piece 45 and the support shaft 42, is engaged with a second arc-like groove 48 which is provided adjacent to the door support -13first arc-like groove 47 on the side of the support shaft 42.

A hinge pin 50 is suspended from the end of the sliding piece 41, and a square tube-like intermediate frame 51 is loosely fitted to the hinge pin 50. The intermediate frame 51 is attached so as to vertically move to a connection block 52 fixed to the upper rail 16 of the sliding door B. In the connection block 52, the tip of c-in adjusting screw 53, penetrating from the under face of the upper rail 16, is helically mated with the intermediate frame 51.

That is, the side of the meeting stiles 18 ofthe sliding door B is supported, with the aid of the slide door support piece 41, by the sash pulley 20 on the meeting stiles.

When the sliding door is being closed, the upper end 44' of the first stopper 44 is brought into contact with the center of the upper rail 1. In other words, the upper end 441 is brought into contact with a projected edge 54 which is provided directly over the guide space 26. As a result, the first stopper 44 falls against the force acting on the coiled spring 43. When the sliding door is being opened, the first stopper 44 rises because of the energy from the coiled spring 43. The lower end 4411 of the first stopper 44 is then brought into contact with the internal end face of a base 411 of the above-described sliding door support piece 41, thereby regulating the rotation in one direction in which the support shaft 42 of the sliding door support piece 41 serves as a fulcrum. When the sliding door is being opened, the rotation of the first stopper 44 in the other direction is regulated by virtue of the fact that the secondstopper 49 is stopped by a projected strip 55, which is vertically arranged on the exterior end of a side wall of the second arc-like groove 48.

The space between the upper rail 16 of the sliding door and the head 1 can be adjusted by operating the adjusting screw 53 mentioned above. Numeral 56 in Fig. 11 denotes a cover plate.

The sash pulley 21 on the front edge of the door is constructed in the following way. It is disposed on the side of the guide member 22 between the sash pulley 20 on the side of the meeting style and the upper guide member 22. As illustrated in Figs. 8 and 9, branch pieces 581, 581 are suspended from a main frame 58, to which wheels 21a, traveling along the upper guide rails 19, are rotatably fixed by axies 57. Support rollers 59, 59 are rotatably fixed to the branch pieces 581, 581, respectively, in both the internal and external directions. A sliding door support frame 60 is arranged so as to protrude from the upper face of the upper rail 16 of the sliding door B. A pair of projected support pieces 601, 601, opposite to the sliding door support frame 60, are vertically disposed in the external direction.

1 ( j -is- The support rollers 59, 59 are supported so as to travel in both the internal and external directions. That is, the side of the door front edge of the sliding door B is supported, with the aid of the sliding door support frame 60, by the sash pulley 21 on the front edge ofthe door. Thus, the position of the sliding door B can change in the internal as well as external directions.

As shown in Fig. 23, the upper guide member 22 is constructed in such a manner that a roller 22a is rotatably fixed to the end of an arm piece 61, whose base is rotatably attached to the front of the sliding door B. The upper section on the front side of the sliding door B travels along the above-described guide space 26 and the bend space 30. The upper section on the front side of the sliding door B travels between the hard frames 3, 31 while it is regulated by the roller 2a of the upper guide member 22.

As shown in Figs. 14 and 16, the lower guide member 24 on the side of the meeting style is constructed in the following way. The base of an arm piece 63, which is bent at the center, is rotatably fixed to a horizontal piece 621 of an attachment piece 62. The attachment piece 62 is attached to the meeting stiles 18 by means of the screws 29. The above-mentioned first roller- 24a and a second roller 24b are arranged parallel to each other, and are rotatably fixed on the front side of the arm piece 63. Both the rollers 24a, 4 -16 24b are engaged with the lower guide rails 23 mentioned above. When the sliding door is being closed, thefirst roller 24 shifts to the groove 32 with the aid of the doorway cut-away section 33, thereby not hindering the closing operation of the sliding section B in the open section R.

Numeral 64 in the drawings designates a support roller for supporting the horizontal piece 621 of the attachment piece 62. The support roller 64 is rotatably fixed to the sill 2.

The operation of the lower section on the side of the meeting style of the sliding door B is regulated by this lower guide member 24 on the side of the meeting style.

The lower guide member 25 on the front edge of the door is mainly shown in Fig. 24. That is, it is constructed in the same manner as that of the upper guide member 22. On the end of an arm piece 65, whose base is rotatably attached to the front edge of the door, the rotatably fixed roller 25a is engaged with the lower guide rails 23. The lower guide member 25 travels along the lower guide rails 23 and the bend rails 34 which communicate with the lower rail 23.

It has a falling A doorway cut-away section 861 of a receiving piece 851 for the lower intermediate drawing piece is provided at the center of the 1 f 0 falling piece 841a.

The receiving piece 851 for the lower intermediate drawing piece is arranged, in a vertical direction, symmetrically with the receiving piece 85 for the upper intermediate drawing piece. The receiving piece 851 for the lower intermediate drawing piece is positioned substantially in the middle of the door edge hard frame 3 and the mullion 4 of the sill 2, and stands on the sill 2 in the vicinity of the sill receiving piece 2b (see Fig. 19).

The front end of the horizontally moving lower frame 821 extends on the side of the hard rail 181. A pressed piece 87, having inclined faces 871, 871 inclining toward the hard frames 3, 31 on the external end thereof, is attached to the end of the frame 821 (see Fig. 25).

The pressed piece 87 comes in or out of contact, in response to the horizontal movement of the horizontally moving lower frame 82', with the internal face of a closed cover 88 for the drainage hole 36. As illustrated in Fig. 24, the closed cover 88 has an elastic piece 88a on the external end thereof, and is arranged while being energized in the open direction by a spring 88. One end of the spring 88 is rotatably fixed to the sill 2.

Numeral 89 in the drawings indicates a support piece which is arranged atthe vertical center of the face 1811 opposite to the mullion 4 in the meeting stiles 18.The 1.

-22meeting stiles 18 are always positioned on the internal side of the above-described fixed section F (see Figs. 5, 6 and 7). The base of a regulating portioh 90 is interposed between a pair of horizontal pieces 89a of the support piece 89. The regulating portion 90 is rotatably fixed, with the aid of a shaft 91, to the horizontal pieces 89a, 89a.

The regulating portion 90 is made of a somewhat groove-like frame composed of a central piece 90a, and regulating pieces 90b, 90b I, which vertically connect to the central piece 90a. A projected piece 901, which extends vertically, is provided on the outside of the central piece 90a. As described above, the end sides of the regulating pieces 90b, 90bl are rotatably fixed to the support piece 89 with the aid of the shaft 91 rotatably energized by coiled the shaft 91 in a clockwise The regulating portion 90 is spring 92 which is wound around direction of Fig. 5. In other words, the regulating portion 90 is energized in a direction in which the projected piece 901 faces the mullion 4; that is, in a direction in which the projected piece 901 moves away from the face 181' opposite to the mullion 4. Because of the force acting on the coiled spring 92, the regulating pieces 90b, 90b ' are positioned so as to be on the vertical tracks of the upper and lower intermediate pieces 73, 73 1 mentioned above. A receiving piece 93 for the upper regulating piece, which stops the upper regulating piece 90b, 1 k -23is provided on the lower end of the upper intermediate piece 73 so as to protrude in the direction of the mullion 4. Similarly, a receiving piece 931 for the lower regulating piece, which stops the lower regulating piece 90bl, is provided on the upper end of the lower intermediate piece 731 so as to protrude in the direction of the mullion 4.

Moreover, as shown in Fig. 2, a roller frame 94 is provided in an appropriate place of the door edge hard frame 3 on the internal side so as to be overlapped by the receiving piece 3b in the internal and the external directions. An auxiliary roller 94a, which presses an interior piece 181b of the hard rail 181, is rotatably fixed to the roller frame 94.

A member indicated by numeral 95 in Figs. 3 and 4 is a spacer to obtain the fixed section F.

The operations of the various components will now be described.

Fig. 8, 22, 23 or 24 shows the state where the sliding door B is completely or partially opened. Under such conditions, as indicated by chain lines in Figs. 5, 6 and 7, the regulating portion 90 rotates by the force acting on the coiled spring 92. It rotates on the shaft 91 clockwise as shown in Fig. 5. The upper regulating piece 90b of the regulating portion 90 is stopped by the receiving piece 93 for the upper regulating piece. On the other hand, the lower regulating piece 90bl of the regulating portion 90 is stopped by the receiving piece 931 for the lower regulating piece. As a result, the upward movement of the -upward moving frame 74 is regulated. The upward moving frame 74 is attached, with the aid of the upper intermediate piece 73, to the receiving piece 93 for the upper regulating piece. On the other hand, the downward movement of the downward moving frame 741 is also regulated. The downward moving frame 74' is attached, with the aid of the lower intermediate piece 731, to the receiving piece 931 for the lower regulating piece. In other words, although the upper and lower intermediate pieces 73, 731 are linked to the pinion 70 by means of the upper and lower racks 71, 711, the knob 68 will not rotate because of the above-described regulation, even if one may try to rotate the knob 68 accidentally.

On the other hand, the sliding door support piece 41 is prevented from rotating because a lower end 4411 of the first stopper 44 is stopped by the internal end face of the base 411 of the sliding door support piece 41, and because the second stopper 49 is stopped by the projected strip 55. Accordinaly, in the same manner as with the side of meeting stiles 18 (door rear edge), a fixed space between the sash pulley 21 on the front edge of the door and the sliding door hard rail 18' (door front) is maintained, thereby regulating the rotations of the arm piece 61 of the upper guide member 22, the arm piece 64 of the lower guide member 24 on the side of the meeting style, and the arm piece 65 of the lower guide member 25 on the front edge of the door. - Under the above conditions, when the sliding door B travels in the direction of the door edge hard frame 3, that is, in the closed direction, the wheels 20a of the sash pulley 20 on the side of the meeting style, and the wheels 21a of the sash pulley 21 on the front edge of the door, travel along the upper guide rails 19. The roller 22a of the upper guide member 22 travels through the guide space 26, and advances into the bend space 30. Also, the rollers 24a, 24b of the lower guide member 24 on the side of the meeting style travel along the lower guide rails 31. (As shown in Fig. 16, the first roller 24a travels to the doorway cut-away section 33.) The roller 25a of the lower guide member 25 on the front edge of the door travels along the lower guide rails 31, and advances into the bend rails 34. The interior piece 181b of the hard rail into contact with the illustrated in Figs.

181 of the sliding door B is brought auxiliary roller 94a. As partially and 16, the sliding door B is arranged so as to cross the window frame A.

At this time, the upper end 441 comes in contact with the projected edge 54, whereby the first stopper 44 falls against the coiled spring 43, and comes off the internal end face of the base 411 of the sliding door support piece 41.

1 k At the same time, the sliding door support frame 60, that is, the hard rail 181 is caused to be capable of traveling in the direction of the sash pulley 21 on the--- front edge of the door, thereby releasing the restriction of the arm pieces 61, 63, 65.

When the operation knob 68 is pressed in order to press the meeting stiles 18 in the external direction, that is, in the direction of the mullion 4, the first roller 24a of the lower guide member 24 on the side of the meeting style travels through the doorway cut-away sect-ion 33 into the grooves 32. The hard rail 181 stays momentarily between the auxiliary roller 94a and the receiving piece 3b of the hard frame 3 on the front edge of the door. The projected piece 901 is stopped by the internal end face of the mullion 4, whereby the regulating portion 90 is caused to rotate against the coiled spring 92. The regulating pieces 90b, 90b' of the regulating portion 90 release the restriction of the receiving pieces for the upper and lower regulating pieces.

The rotation of the operation knob 68 is thus made possible.

Furthermore, when the operation knob 68 is rotated, the pinion 70 attached to the rotary shaft 69 rotates, thereby causing the upper and lower racks 71, 711 to move vertically.

Because of the ascent of the upper rack 71, the upward moving frame 74 ascends with the aid of the upper intermediate piece 73. The upward drawing member 75 connected to the upward J i 1 -27 moving frame 74 also ascends. The upward separating projection 77, provided on the upward drawing member 75, comes in contact and overlaps with the upper separate receiving piece 78. Moreover, because of the descent of the lower rack 711, the downward moving frame 741 descends with the aid of the lower intermediate piece 731. The downward drawing member 751 connected to the downward moving frame 74' also descends. The downward separating projection 771, provided on the downward drawing member 751, comes in contact and overlaps with the lower separate receiving piece 781.

The hard rail 181 is inserted into the space between the auxiliary roller 94a and the receiving piece 3b by virtue of the fact that the upward separating projection 77 comes in contact and overlaps with the upper separate receiving piece 78, and also by virtue of the fact that the downward separating projection 771 comes in contact and overlaps with the lower separate receiving piece 78 1. The sliding door B thus stands between the mullion 4 and the door edge hard frame 3. In other words, the position of the sliding door B changes so as to face in the external direction, and closes the open section R.

Moreover, as shown in Fig. 10 or 11, because of the ascent of the upper drawing member 75, the upward drawing piece 76, attached to the upper drawing member 75, is brought into contact with the upward drawing roller 40. Furthermore, 4 -28as shown in Fig. 11, because of the descent of the lower drawing member 751, the downward drawing piece 761, attached to the lower drawing member 751, is brought into contact tiwh the second intermediate piece 2e of the sill 2. As a result, the upper and lower parts of the mee.ting stiles 18 of the sliding door B are drawn. (Thus side of the hard rail 181 is drawn toward the side of the receiving piece 3b of the door edge hard frame 3 by virtue of the fact that the side of the hard rail 181 is pressed into contact with the auxiliary roller 94.) Also, the intermediate section of the meeting stiles 18 is drawn toward the external direction due to the fact that the upper and lower intermediate drawing rollers 79, 791 are pressed into contact with the intermediate drawing pieces 13, 131. The upper and lower intermediate drawing rollers 79, 791 are arranged on the upward and downward moving frames 74, 741. The intermediate drawing pieces 13, 131 are disposed on the inner face 4' of the mullion 4.

As the upper drawing member 75 ascends, the horizontally moving upper frame 82 advances, with the aid of the upper leaf spring 80, in the direction of the hard rail 181 (the door edge hard frame 3). By the operation in which the sliding door B is pressed so that its position changes to face in the external direction, the upper intermediate drawing piece 84, attached to the horizontally moving upper 1 frame 82, is pressed into contact with the external side face of the upper intermediate drawing piece 85. The upper intermediate drawing piece 85 is positioned, with the aid of the doorway cut-away section 86, on the internal side of the rising piece 84a. Furthermore, as the lower drawig member 751 descends, the horizontally moving lower -frame 82' advances, with the aid of the lower leaf spring 82, in the direction of hard rail 181 (the door edge hard frame 3). By the operation in which the sliding door B is pressed so that its position changes to face in the external direction, the lower intermediate drawing piece 841, attached to the horizontally moving lower frame 821, is pressed into contact with the external side face of the lower intermediate drawing piece 851. The lower intermediate drawing piece 851 is positioned, with the aid of the doorway cut-away section 861, on the internal side of the falling piece 84a. Due to the pressure contact of the upper and mentioned above, the intermediate sections lower rails 16, 17 of the sliding door B are drawn in the external direction.

As illustrated in Fig. 2 or 19, by joining together various components mentioned above, it is possible to obtain the air- and water-tight conditions on the external side by virtue of the fact that the end 7' of the first air- and watertight material 7 contacts the dry air and watertight material 10 of the sliding door B. The first air- and 1 1 -30water-tight material 7 is provided so as to cover the open section R, and is arranged respectively on the exterior piece la of the head 1, the exterior piece 2a- of the sill 2, the exterior piece 3a of the door edge hard frame 3, and the exterior piece 4a of the mullion 4.. Moreover, it is also possible to obtain the air- and water-tight conditions on the internal side by virtue of the fact that the ends 151 of the second airand water-tight materials 15 contact the piece 16c of the upper rail 16, the piece 17c of the lower rail 17, the piece 18c of the meeting stiles 18, and a piece 181c of the hard rail 181. All of the above-mentioned pieces are attached to the sliding door B. The second air- and water-tight materials 15 are attached respectively to the receiving piece lb of the head 1, the receiving piece 2b of the sill 2, the receiving piece 3b of the door edge hard frame 3, and the first step lla of the mullion 4.

In addition, the pressed piece 87, attached to the horizontally moving lower frame 821, presses against the closed cover 88, which closes the drainage hole 36.

As has been described above, it is possible to close the open section R by means of the sliding door B. As shown in Fig. 2, when it is closed, the sliding door B is arranged flush with the fixed section F, whereby the outward appearance of the single sliding sash according to the present invention becomes similar to that of a fixed window.

) 4 The open section R can be opened owing to the fact that the various components mentioned above return to their original positions by operating the operating knob 68. The opening operation is the same as that for the closing operation mentioned above, except the procedures of the closing operation are reverse. The explanation of the opening operation, therefore, will be omitted.
