Description

  The sliding door device with a brake device according to the present invention is used to prevent a part of the body from being caught between the window frame and the sliding door shoji, or to prevent the window frame and the sliding door shoji from colliding with force. .

  Conventionally, means for preventing a part of a body such as a finger from being caught between an opening such as an entrance and a sliding door for closing the opening has been considered. Describes a sliding door device with a braking device that exerts a braking force against the movement of the sliding door at the end of the movement when an upwardly suspended sliding door (so-called hanging door) moves in the closing direction. 20-21 has shown the 1st example of the sliding door apparatus with a brake device of the conventional structure described in patent document 1 among these. In the case of the first example of this conventional structure, the rail 2 is disposed horizontally above the opening 1, and a pair of suspension wheels 4, 4 are attached to the upper end surface of the sliding door shoji 3 via the hanger members 5, 5. And is supported rotatably. Then, by engaging these suspension wheels 4 and 4 with respect to the rail 2 from above, the upper end portion of the sliding door shoji 3 is supported so as to be movable in parallel (horizontal movement) along the rail 2.

  In the case of the first example of the conventional structure, the rack 6 is supported in the horizontal direction at a position above the rail 2. Further, a hanger member 5 provided on one end side (right side in FIG. 20) of the sliding door shoji 3 at a position above the sliding door shoji 3 is provided with a braking device body 8 having a pinion 7 engageable with the rack 6. The support is fixed. The braking device main body 8 is provided with resistance applying means for increasing the rotational resistance of the pinion 7 only when the pinion 7 rotates in a predetermined direction. Specifically, as shown in FIG. 21, the pinion 7 is supported on one end (upper end in FIG. 21) of the pivot 10 via the one-way clutch 9, and on the other end of the pivot 10. The rotating body 11 is supported. The rotating body 11 is filled with a viscous fluid 12 that functions as the resistance applying means. In the case of the first example of the conventional structure, the rack 6 and the brake device main body 8 constitute the brake device 13.

  In particular, in the case of the first example of the conventional structure, the rotation of the pinion 7 is changed to the pivot 10 (and the rotation) only when the pinion 7 rotates with the movement of the sliding door shoji 3 in the closing direction. The mounting direction of the one-way clutch 9 is restricted so as to be transmitted to the body 11). For this reason, when the sliding door shoji 3 moves in the closing direction and the pinion 7 meshes with the rack 6, the rotating body 11 is rotated in the viscous fluid 12. For this reason, the rotational resistance of the pinion 7 increases due to the viscous resistance acting on the rotating body 11. As a result, when the sliding door 3 moves in the closing direction and reaches the vicinity of the closing position, a braking force can be applied to the sliding door 3. On the other hand, when the pinion 7 rotates with the movement of the sliding door 3 in the opening direction, the sliding movement of the sliding door 3 to rotate the pinion 7 around the pivot 10. On the other hand, no braking force is applied.

  Moreover, as what provided the braking device in sliding door apparatuses other than the above-described suspension type sliding door apparatus, the structure described in patent documents 7, 8, etc. is known, for example. FIG. 22 shows a sliding door device with a brake device according to a second example of the conventional structure described in Patent Document 7 among them. In the case of the second example of this conventional structure, a configuration is adopted in which the upper end portion of the sliding door shoji 3a is inserted into a guide groove 15 formed on the lower surface of the upper frame 14, and the braking device 13a is connected to the sliding door. It is provided in the space between the upper end surface of the shoji 3 a and the lower surface of the guide groove 15.

  Specifically, a U-shaped receiving member 16 having a rack 6a on the inner surface is supported and fixed to the lower surface of the guide groove 15, and the upper end surface of the sliding door 3a can be engaged with the rack 6a. A braking device main body 8a having a pinion 7a is supported and fixed. Thereby, this pinion 7a and the said rack 6a are meshed | engaged in the front and back direction of the said sliding door shoji 3a. Particularly, in the case of the second example of the conventional structure, a concave portion 17 is formed on the upper end surface of the sliding door shoji 3a, and the braking device main body 8a is accommodated in the concave portion 17 so as to be movable up and down. In the case of the second example of the conventional structure, the vertical position restricting means for projecting the pinion 7a from the recess 17 only when the sliding door 3a moves in the closing direction and reaches the vicinity of the closing position. Provided. Also in the case of the second example of the conventional structure configured as described above, when the pinion 7a and the rack 6a mesh with each other, the action of the resistance applying means provided in the braking device main body 8a causes the pinion 7a to move. The rotational resistance is increased, and a braking force is applied to the sliding door shoji 3a.

  By the way, any of the conventionally proposed sliding door devices with a braking device is intended for the above-described suspension type sliding door device as shown in the first example of the conventional structure, or the second example of the conventional structure described above. As shown in Fig. 3, the sliding frame device has a simple structure that allows easy engagement between the upper frame and the upper end of the sliding door shoji, and can secure a large space between the lower surface of the upper frame and the upper end surface of the sliding door shoji. Limited to what you do. Furthermore, many of them have a structure including a self-closing device that biases the sliding door shoji in the closing direction. That is, the conventionally proposed sliding door device with a brake device is a structure that can secure a sufficient space for assembling the brake device, and is intended for a sliding door that is relatively light.

  However, the sliding door shoji that performs the closing operation has a larger inertial mass than the lightweight sliding door shoji because the weight of the sliding door shoji is large. If a part of the body such as a finger is sandwiched between the opening and the opening, it may lead to a major accident. For this reason, in order to ensure sufficient safety and quietness when closing a heavy sliding door shoji, it is desirable to take some measures, and it is desirable to exhibit the braking function by the braking device as described above. It is. In particular, sliding door shojis built in window frames have recently been improved in sound insulation, high heat insulation, wind pressure resistance, etc., and large glass panels may be used to ensure daylighting. And its weight tends to increase. Moreover, the weight of a sliding door shoji increases also by using a multilayer glass panel. Therefore, it is necessary to incorporate a braking device even for a sliding door device composed of such a window frame and a sliding door shoji built in the window frame. However, an upper guide rail for guiding the sliding door shoji is provided between the upper frame constituting the upper side of the window frame and the upper arm constituting the upper side of the sliding door shoji. The space is limited, and it is not possible to incorporate a braking device for a sliding door device by using the conventionally known structures such as the first and second examples of the conventional structure as they are.

Further, each of the respective sliding door Shoji, a stile on constituting the upper side, and lower frame constituting the lower side, by a vertical stile of a pair that constitute the left and right vertical side, is configured to surround the four sides of the glass panel Yes.
And the upper guide rail provided in the lower surface of the said upper frame is engaged with the guide groove formed in the guide block each supported by the upper end part of each of these ridges, and the doorwheel provided in the said lower ridge is made into the said By engaging with a lower guide rail provided on the upper surface of the lower frame, each sliding door shoji is built in the window frame so as to be horizontally movable.
Further, each of the respective braking device has a rack which is arranged in the horizontal direction, the rack meshing freely pinion, the pinion only when rotating along with the movement of the closing direction of the respective sliding door shoji, The braking device main body is provided with a resistance applying means for increasing the rotational resistance of the pinion.

In particular, in the braking device with the sliding door device of the present invention, among the above rack, the rack for applying a braking force to the sliding door shoji outdoor side, of the member fixed to the upper side of the window opening above A pair of locking grooves, which are provided adjacent to the indoor side of the upper frame and separated in the indoor and outdoor directions, are provided on the indoor side in the locking groove on the outdoor side of the attachment for attachment that is open on the lower surface. A rack for applying a braking force to the sliding door screen is supported and fixed in the indoor engagement groove of the attachment for attachment , and each of the braking device main bodies is connected to the sliding door screen on the outdoor side and the indoor side. Among them, on the inner side surface of the upper end room of the cage or the indoor side surface of the upper cage, via the spacer, the mounting position in the vertical direction is adjustable and supported, and each of the above-mentioned by the cover attached to each of these spacers Braking device book Covering the other of the upper space. The attachment for attachment can be attached to the upper frame, the frame, the saddle plate, the curtain box or the like.

According to the present invention configured as described above, a sliding door device including a window frame provided in a window opening and a pair of sliding door shojis built in the window frame has a closing direction of each of these sliding door shojis. A braking device can be incorporated to brake movement to That is, in the case of the sliding door device with a braking device of the present invention, the assembling property of the braking device is ensured by effectively using the space on the indoor side of the sliding door shoji. Therefore, when the sliding door shoji moves in the closing direction and reaches the vicinity of the closing position, a braking force can be applied to the sliding door shoji. For this reason, it is possible to prevent a part of the body from being caught between the sliding door shoji and the window frame, and to prevent the sliding door shoji and the window frame from colliding with force. As a result, even when a sliding door with a large weight is used, safety and quietness at the time of closing can be ensured.

In the case of the present invention, the brake device body is supported and fixed by using a spacer so that the mounting position in the vertical direction can be adjusted. For this reason, by appropriately regulating the shape, dimensions, etc. of the spacer, it is possible to use a brake device body that has been conventionally used in other types of sliding door devices. Moreover, the adjustment work regarding the up-down direction for meshing the pinion constituting the braking device with the rack can also be performed.
Furthermore, according to the present invention, it is possible to prevent a part of the body (mainly the head) from coming into contact with the pinion (the lower part thereof) and prevent a curtain or the like from being caught. Furthermore, the appearance and appearance of the sliding door shoji provided with the braking device main body can be secured satisfactorily by the cover.

[First example of embodiment]
1 to 5 show a first example of an embodiment of the present invention . In the case of this example, a pair of glass shojis 19a and 19b, each of which is a sliding door shoji described in the claims, are built inside the window frame 18 in a sliding manner. Of these, the window frame 18 is formed in a rectangular shape by an upper frame 20 constituting the upper side, a lower frame 21 constituting the lower side, and collar frames 22a and 22b constituting the left and right vertical sides. Each of these frames 20, 21, 22a, 22b is made of an integrally extruded material of aluminum alloy. Further, each of the glass shojis 19a and 19b are upper ridges 23a and 23b that constitute the upper sides thereof, and lower ridges 24a and 24b that also constitute the lower sides, respectively, that are ridges that constitute the left and right vertical sides. The summing rods 25a and 25b and the butting rods 26a and 26b surround the four sides of the glass panels 27a and 27b. Each of these flanges 23a, 23b, 24a, 24b, 25a, 25b, 26a, and 26b is also made of an integrally extruded material of aluminum alloy. Among these, the summoning tubs 25a and 25b are located in the center of the window frame 18 when the glass shojis 19a and 19b are closed, and face each other in the indoor and outdoor directions. In contrast, each of the butting rods 26a and 26b is positioned at the end of the window frame 18 when the glass shojis 19a and 19b are closed, and is butted against the rib frames 22a and 22b. In the case of this example, as the glass panels 27a and 27b, multi-layer (double) glass panels are used.

A pair of upper guide rails 28a and 28b are provided on the lower surface of the upper frame 20 so as to be separated from each other in the indoor and outdoor directions. The upper guide rails 28a and 28b are engaged with the guide grooves 30a and 30b formed in the guide blocks 29a and 29b supported on the upper ends of the summing rods 25a and 25b and the butting rods 26a and 26b. . With this configuration, the upper ends of the glass shojis 19a and 19b are supported so as to be movable along the upper frame 20. On the other hand, the lower frame 21 is provided with a pair of lower guide rails 31a and 31b that are separated from each other indoors and outdoors. Then, the door guides 32a and 32b (see FIG. 7 described later) provided in the vicinity of both ends of the lower rods 24a and 24b constituting the lower sides of the glass shojis 19a and 19b are connected to the lower guide rails 31a and 31b. Engaged. As a result, the glass shojis 19a and 19b are supported at a position above the lower frame 21 so as to freely move horizontally along the lower frame 21.
With the above configuration, the glass shojis 19a and 19b are built inside the window frame 18 so as to be horizontally movable.

  In particular, in the case of the present example, when the glass shoji 19a built on the outdoor side moves in the closing direction and reaches the vicinity of the closing position (with the opening width remaining about 30 to 40 cm), A braking device 13b for applying a braking force to the glass shoji 19a is provided. In the case of this example, as the braking device 13b, the one constituted by the rack 6b and the braking device main body 8b is used in the same manner as the braking devices 13 and 13a having the conventional structure described above (see FIGS. 20 to 22). ing. The brake device main body 8b increases the rotational resistance of the pinion 7b only when the pinion 7b engageable with the rack 6b and the pinion 7b rotate as the glass shoddle 19a moves in the closing direction. A resistance applying means. In the case of this example, the structure of the resistance applying means capable of exhibiting such a function is not particularly limited. For example, as shown in FIG. 21, a viscous fluid is filled around a rotating body that rotates together with a pinion. It is possible to employ a structure such as a structure in which a friction member is pressed against a rotating body that rotates together with a pinion using an elastic material such as a spring. In any case, in the case of this example, the resistance applying means capable of exhibiting the function as described above is housed inside the substantially cylindrical case 33.

  In particular, in the case of this example, the rack 6b is supported and fixed to a portion near one end of the upper frame 20 constituting the upper side of the window frame 18 (the left side portion in FIG. 1), and the brake device main body 8b is fixed. The glass shoji 19a is supported and fixed to the inner surface of the upper end chamber of the butting rod 26a constituting the vertical side. Therefore, in this example, the rack 6b is supported and fixed to a portion near one end of the upper frame 20 by using a rack mounting attachment 34. The rack attachment 34 includes a crank-shaped stay 37 fixed to a protruding plate portion 35 provided on an indoor side surface of the upper frame 20 by screws 36a from below, and an indoor side of the upper frame 20. Are fixed by screws 36b and 36c from below to a wooden frame 38 provided in

  A pair of locking grooves 39a and 39b are provided on the lower surface of the rack mounting attachment 34 as described above in a state of being separated in the indoor and outdoor directions. In the case of this example, the rack 6b is locked to the locking groove 39a on the outdoor side of the locking grooves 39a and 39b. In the case of this example, the rack 6b has a substantially T-shaped cross section, and its base end is locked in the locking groove 39a. Specifically, by caulking and fixing the base end portion of the rack 6b, or by supporting blocking members (not shown) on both sides of the rack 6b in the longitudinal direction of the locking groove 39a, The rack 6b is prevented from being displaced in the locking groove 39a in the opening / closing direction of the glass shoji 19a. In the case of this example, the rack mounting attachment 34 is made of an integrally extruded material of aluminum alloy and has a length dimension substantially equal to the entire length of the upper frame 20. However, a rack slightly larger than the length of each rack 6b (about 30 cm) may be used. Further, the rack mounting attachment 34 used in this example is not a dedicated product for locking only the rack 6b for braking the outdoor glass shoddle 19a. The rack 6b for braking the glass shoji 19b is also locked (see FIGS. 7 to 9 described later).

  In the case of this example, the braking device main body 8b is coupled to the inner surface of the upper end chamber of the butting rod 26a via a positioning spacer 40 as shown in FIGS. For this purpose, the positioning spacer 40 is screwed and fixed to the inner surface of the upper end chamber of the butting bar 26a with a pair of screws 41 and 41. Further, a reinforcing member 42 having a U-shaped cross section is provided on the inside of the butting bar 26a, and the coupling strength of the positioning spacer 40 to the butting bar 26a is increased. In the case of this example, since the positioning spacer 40 is made of synthetic resin, a metal washer (not shown) is provided between the positioning spacer 40 and the indoor side surface of the butting rod 26a. Is pinched. The reinforcing member 42 is inserted in advance from above the butting bar 26a and fixed with screws in a state in which the glass shoddle 19a is removed from the window frame 18.

  In the case of this example, the braking device main body 8b is coupled to the positioning spacer 40 coupled as described above in the following manner. That is, the rear surface of the case 33 is brought into contact with the positioning spacer 40 in a state in which the rotation shaft of the pinion 7b constituting the braking device main body 8b is arranged indoors and outdoors, and a part of the outer peripheral surface of the case 33 A mounting plate portion 43 provided below (under FIGS. 2, 3, and 5) is fixed to the positioning spacer 40 with screws.

  Specifically, the mounting plate portion 43 is screwed and fixed to a pair of receiving portions 44, 44 provided on both side portions of the positioning spacer 40. For this purpose, each of the receiving portions 44, 44 can be inserted with screws 45, 45 inserted through the mounting plate portion 43, and can be inserted into the long holes 46, 46 which are long in the vertical direction. Concave portions 48 and 48 are formed for accommodating free plate nuts 47 and 47. Then, the screws 45, 45 inserted into the long holes 46, 46 and the plate nuts 47, 47 are screwed and fastened, whereby the mounting plate portion 43 is fixed to the receiving portions 44, 44. It is fixed with screws. In the case of this example, the screws 45, 45 are inserted into the long holes 46, 46 which are long in the vertical direction, so that the mounting position of the braking device body 8b with respect to the positioning spacer 40 is determined. Can be adjusted up and down. Thereby, the adjustment work regarding the up-down direction for meshing the pinion 7b with the rack 6b can be performed. In the case of this example, by appropriately regulating the thickness dimension of the positioning spacer 40 in the indoor / outdoor direction, the indoor / outdoor position of the pinion 7b is made the same as the indoor / outdoor position of the rack 6b. ing.

  In the case of this example, the cover 49 is attached so as to cover the area other than the upper space of the braking device main body 8b. That is, by engaging the locking claws 50, 50 provided on the inner surface of the cover 49 with the locking recesses 51, 51 provided on the outer surface of the upper ends of the receiving parts 44, 44, The cover 49 is attached to the positioning spacer 40 so as to cover the braking device main body 8b. In the case of this example, by providing such a cover 49, it is possible to prevent a part of the body (mainly the head) from coming into contact with the pinion 7b (the lower part thereof), and a curtain or the like is involved. I try to prevent things. Furthermore, the cover 49 ensures a good appearance and appearance of the glass shoji 19a provided with the braking device main body 8b.

  As described above, in the case of this example, the braking device 13b is assembled using the space on the indoor side of the window frame 18 and the glass shoji 19a. Therefore, in the case of this example, when the sliding door 19a moves in the closing direction and reaches the vicinity of the closing position, the rack 6b and the pinion 7b mesh with each other and rotate by the action of the resistance applying means. The pinion 7b having increased resistance is rotated. For this reason, a braking force can be applied to the sliding door shoji 19a. Accordingly, it is possible to prevent a part of the body from being caught between the sliding door shoji 19a and the heel frame 22a constituting the vertical side of the window frame 18, and the sliding door shoji 19a and the heel frame 22a collide vigorously. Can be prevented. For this reason, as in this example, even when the sliding door shoji 19a is increased in weight by incorporating the multi-layer glass panel 27a, the safety and quietness at the time of closing can be sufficiently secured. .

  In the case of this example, since the braking device body 8b is supported and fixed via the positioning spacer 40, the braking device body 8b that has been conventionally used for other types of sliding door devices is used as it is. Can be used. In other words, in the case of this example, it is not necessary to prepare a dedicated braking device body 8b, and the existing one can be used as it is.

  In the case of this example, since both the rack 6b and the braking device main body 8b constituting the braking device 13b are mounted in the indoor space of the sliding door device, the braking device 13b is newly constructed. It can be attached not only to the sliding door device attached to the building but also to the existing sliding door device already attached to the building. Furthermore, not only can the safety during the mounting operation of the braking device 13b be ensured, but also the work efficiency of the mounting operation can be improved. Further, the influence of dust, rain, solar radiation and the like can be reduced, which is advantageous in terms of ensuring the durability of the braking device 13b.

  In addition, the structure of this example is applicable not only to the glass shod 19a on the outdoor side but also to the glass shod 19b on the indoor side as it is. FIGS. 6 to 9 show a structure in which a braking device 13b is incorporated in order to brake the movement of the indoor glass shroud 19b in the closing direction. However, also in this case, the braking device main body 8b used for the outdoor glass shroud 19a cannot be used as it is for the indoor glass shroud 19b, and the rotation direction of the pinion 7b that increases the rotational resistance by the resistance applying means. Must be reversed. For this purpose, for example, if the one-way clutch as shown in the first example of the conventional structure described above is used, the one-way clutch can be attached in the opposite direction between the outdoor side and the indoor side. The same braking device main body 8b can be used for the glass shoji 19a and the indoor glass shoji 19b.

[One Reference Example Related to the Present Invention]
10 to 12 show an example of a reference example related to the present invention. Even in this reference example, the structure of the sliding door device to be applied is a sliding door as in the first example of the embodiment described above. In the case of this reference example, two sets of braking devices 13c and 13c are provided in order to brake the movement in the closing direction of both the outdoor and indoor glass shojis 19a and 19b. However, in the case of this reference example, the braking resistance 13c for braking the outdoor glass shroud 19a and the braking apparatus 13c for braking the indoor glass shroud 19b are provided with rotational resistance by resistance applying means. Since the basic configuration is the same except that the rotation direction of the pinion to be enlarged is reversed, the following description is made on the braking device 13c provided for braking the outdoor glass shoji 19a. .

  Also in this reference example, the braking device 13c includes a rack 6c and a braking device main body 8c. The braking device main body 8c includes a pinion 7c that can be meshed with the rack 6c, and resistance applying means. I have. In the case of the present reference example, the rack 6c is supported on the upper collar 23a constituting the upper side of the glass shoji 19a so as to be only movable up and down, and the brake device body 8c is supported on the upper side of the window frame 18. The upper frame 20 is supported and fixed.

  Specifically, the rack 6c is protruded from the upper end surface of the upper collar 23a with its tooth tip surface facing upward, and by engagement between a long hole in the vertical direction and a guide pin, The upper collar 23a is supported to be movable up and down. Further, the lower surface of both ends of the rack 6c is supported in a space (indoor side space) adjacent to the locking groove 52 that engages with the upper guide rail 28a among the upper end portions of the upper collar 23a, and the rack Vertical position adjusting devices 53 and 53 that can adjust the vertical position of 6c are provided. Each of the vertical position adjusting devices 53 and 53 includes a stopper 54 screwed to the bottom wall portion of the locking groove 52 and an adjustment piece 55 rotatably supported by the stopper 54. . The adjustment piece 55 includes a pair of fitting pieces 56a and 56b and a projecting piece 57 provided between the fitting pieces 56a and 56b. The uppermost portion of the projecting piece 57 is brought into contact with a part of a recess 68 provided on the bottom side of the rack 6c. In FIGS. 11 and 12, the protrusion 57 and the recess 68 are omitted.

  Further, among the fitting pieces 56a and 56b, the indoor side end surface of the fitting piece 56a provided on the indoor side is formed with an engagement groove that can be engaged with a tool such as a screwdriver. The outer peripheral surface of the fitting piece 56b provided in is formed in a gear shape. A part of the stopper 54 is engaged with the outer peripheral surface of the fitting piece 56b to provide resistance against rotation of the fitting piece 56b and the protruding piece 57. In the case of this reference example, a through-hole through which the tool can be inserted is formed on the indoor side surface of the upper collar 23 a and is closed by a cap 58.

  Each of the vertical position braking devices 53, 53 configured in this way rotates the indoor fitting piece 56a using a tool, and rotates the protruding piece 57 together with the fitting piece 56a. The contact position between the recess 68 provided at the bottom of the rack 6c and the protrusion 57 is changed (the uppermost position of the protrusion 57 that is in contact with the recess 68 is changed in the vertical direction. And the vertical position of the rack 6c is adjusted. In the case of this reference example, as described above, by locking a part of the stopper 54 to the outer peripheral surface of the outdoor fitting piece 56b, the protruding piece 57 is rotated by a tool. Rotation is prevented except for motion. In the case of the present reference example, the protrusion 57 and the concave portion provided on the bottom side of the rack 6c come into contact with each other, so that the rack 6c can be prevented from being displaced in the length direction. (The engaging portion between the long hole and the pin described above can be omitted).

  On the other hand, in the case of the present reference example, the brake device main body 8c is disposed on the lower surface of the upper frame 20, and the rotation shaft of the pinion 7c constituting the brake device main body 8c is arranged indoors and outdoors (horizontal direction). It is fixed with support. Specifically, the braking device body 8c is supported and fixed to a portion closer to the indoor side than the upper guide rail 28a on the lower surface of the upper frame 20 via a positioning spacer 40a having an L-shaped cross section.

  As described above, in the case of this reference example, the presence of the upper guide rail 28a makes it difficult to secure a wide space in the indoor / outdoor direction, between the upper frame 20 and the upper collar 23a. By using the space in the vertical direction, the braking device 13c is assembled in this space. Therefore, also in the case of this reference example, when the sliding door 19a moves in the closing direction and reaches the vicinity of the closing position, the pinion 7c and the rack 6c constituting the braking device main body 8c are moved in the vertical direction. By engaging, a braking force can be applied to the sliding door shoji 19a.

In particular, in the case of this reference example, the vertical position of the rack 6c can be adjusted from the indoor side using a tool, and therefore the vertical direction for making the meshing state between the rack 6c and the pinion 7c appropriate. Adjustment work can be done easily. Further, the rack 6a does not hinder the work of installing the sliding door shoji 19a.
Other configurations and operations are the same as those in the first example of the embodiment described above.

[Second Example of Embodiment]

The feature of the second example is that the summing fence 25b constituting the vertical side of the indoor side glass shoddle 19b is prevented from colliding with the gutter frame 22a constituting the window frame 18, so that the outdoor side glass shoddle is 19a is provided with stopper members 59a and 59b. Other configurations and operations are the same as the structure of the first example of the embodiment of the present invention described above. For this reason, the overlapping description will be omitted or simplified, and the following description will focus on the features of this example.

  In the case of this example, each said stopper member 59a, 59b is each provided in the indoor side surface of the upper end part and lower end part of the butting rod 26a among the said glass shoji 19a. Particularly in the case of this example, a stopper member 59a provided at the upper end of the butting rod 26a is integrally provided at the lower end of the positioning spacer 40a. That is, an abutting member 61a made of an elastic material such as a synthetic resin or rubber is coupled to an attachment portion 60a having an L-shaped cross section formed integrally with the lower end portion of the positioning spacer 40a to form the stopper member 59a. . For this reason, the front-end | tip part of this contact member 61a is arrange | positioned in the center side of the window frame 18 rather than the cover 49 which covers the braking device main body 8b. In the case of this example, the mounting portion 60a is screwed and fixed to the indoor side surface of the butting rod 26a with a screw 62. Accordingly, the reinforcing member 42a provided inside the butting rod 26a is longer than the first example of the above-described embodiment.

  On the other hand, the stopper member 59b provided at the lower end portion of the butting rod 26a is composed of a mounting portion 60b having a substantially L-shaped cross section and an abutting member 61b. It is fixed with screws to the lower end of the butting bar 26a. In the case of this example, the reinforcing plate 63 is provided on the inner side of the lower end portion of the butting bar 26a, so that the coupling strength of the stopper member 59b to the butting bar 26a is increased. In the case of this example, the tip portions of the both contact members 61a and 61b constituting the stopper members 59a and 59b can be simultaneously contacted with the summing bowl 25b of the sliding door sliding door 19b on the indoor side. In addition, the mounting position is regulated.

In the case of this example configured as described above, even when the indoor glass shoddle 19b is moved in the opening direction, the summing bar 25b of the glass shoddle 19b is moved to the stopper members 59a and 59b (contact). The members 61a and 61b) can be brought into contact with each other. For this reason, it is possible to prevent the summoning collar 25b from colliding with the collar frame 22a and damaging the crescent 69 or the like. Particularly in the case of this example, since the stopper member 59a is provided integrally with the positioning spacer 40a, it is easier to ensure the bonding strength to the butt bar 26a than when the stopper member 59a is provided alone. You can plan. Further, since the positioning spacer 40a and the mounting portion 60a constituting the stopper member 59a can be manufactured at the same time by integral molding of synthetic resin, the manufacturing operation can be shortened, which is advantageous in terms of manufacturing cost. Further, by reducing the number of parts, the part management cost can be reduced, and the mounting work for mounting the stopper member 59a can be omitted.
About the structure of another part, it is the same as that of the structure described in the 1st example of embodiment of this Example mentioned above.

  In the first example and the second example of the embodiment described above, the stay plate 37 is screwed and fixed to the projecting plate portion 35 of the upper frame 20 from below, and the projecting plate portion 35 and the wooden picture frame are used. A structure for assembling the rack mounting attachment 34 to 38 is shown. However, the structure for assembling the rack mounting attachment 34 is not limited to the frame 38, for example, a slat 64 as shown in FIG. 17A or a curtain box 65 as shown in FIG. It can also be configured using. And according to such a structure, the above-mentioned stay 37 and the rack attachment 34 supported by this stay 37, as well as the sliding door device not yet attached to the building, have already been attached to the building. Can also be attached to.

  On the other hand, when only the sliding door device not yet attached to the building is targeted, it is possible to employ a structure in which the stay 37 is screwed and fixed to the protruding plate portion 35 of the upper frame 20 from above. . Even in such a configuration, as shown in FIGS. 18A to 18C, it is possible to use the wooden picture frame 38, the roof 64, and the curtain box 65.

  Further, as another configuration of the rack mounting attachment shown in the first example and the second example of the above-described embodiment, for example, a configuration as shown in FIGS. 19A to 19C is adopted. Can do. FIG. 19A shows a configuration in which an engaging portion 66 provided on the upper surface of the rack mounting attachment 34 is engaged with the distal end portion of the stay 37. According to such a configuration, the rack mounting attachment 34 can be temporarily supported on the stay 37 in a state before being fixed to the stay 37 with screws. FIG. 2B shows a configuration in which the bottom portion of the locking groove 39a of the rack mounting attachment 34 is directly screwed and fixed to the protruding plate portion 35 with a screw 67 inserted from below. According to such a configuration, the mounting work of the rack mounting attachment 34 can be simplified. Further, (c) in the figure shows that the locking grooves 39a and 39b for locking the base end of the rack 6b are engaged with other locking members 68a and 68b independent of the rack mounting attachment 34. The structure which stops is shown. According to such a configuration, the rack 6b can be easily attached and the unnecessary locking member 68b (68a) can be removed.

  Further, regarding the vertical position adjusting device 53 shown in one example of the reference example described above, the following configuration can be adopted in addition to forming the concave portion on the bottom side of the rack. That is, although not shown in the drawings, as described above, long holes in the vertical direction are formed at both ends in the length direction of the rack, and support pins are inserted into the respective long holes. Support both ends with stoppers. By adopting such a configuration, it is possible to effectively prevent the rack from being displaced in the length direction due to the engagement between the support pins and the long holes without providing a recess on the bottom side of the rack. .
