These are the watertight projections 319 of the sliding door 31 and the watertight projections 3 of the sliding door 32 when the sliding doors 31, 32, 33 are completely closed.
28, and the watertight projection 329 of the sliding door 32 and the watertight projection 338 of the sliding door 33 are in close contact with each other to ensure the watertightness of the gap between them. Each of the tips that come into close contact with each other is covered with a cushioning sealing material made of rubber or plastic, so that the sealing property at the time of close contact is enhanced.

(Second Conventional Example) FIG. 12 shows a sliding door device 10B as a second conventional example. In the figure, the basic configuration of each sliding door 31, 32, 33 and frame 20 (upper frame 21, lower frame 2
2, vertical frames 23, 24, mounting members 231, 241, frame members 232, 242, screws
239, 249, wall surfaces 230, 240, and inner frame 200) are the same as those of the above-described sliding door device 10A (first conventional example). The difference in the sliding door device 10B is that a structure for inserting the screws 239, 249 into the frame members 232, 242 is added.

As shown in FIG. 13, each frame member 232, 242
Has recesses 238, 248 in the door stop portion, and the bottom surface thereof has an insertion hole 23 of a size that allows the screws 239, 249 to be easily inserted.
7,247 are formed in plurality. Covers 236, 246 also serving as door stop members are fitted and fixed to the openings of the concave grooves 238, 248, and caps 235, 245 are fitted into the respective insertion holes 237, 247.

The installation of the sliding door device 10B is performed in the following procedure. First, the frame body 20 is previously arranged between the wall surfaces 230 and 240 where the sliding door device 10B is installed. At this time, the inner frame 200
The attachment members 231 and 241 are housed in the frame members 232 and 242 of FIG. Next, the inner frame 200 arranged between the wall surfaces 230 and 240
The mounting members 231 and 241 are advanced from the frame members 232 and 242 and contact the opposing wall surfaces 230 and 240, respectively.

Subsequently, screws 239, 249 are driven into the wall surfaces 230, 240 through the respective insertion holes 237, 247 in the concave grooves 238, 248 of the frame members 232, 242 so as to penetrate the mounting members 231, 241.
231,241 is fixed to wall surfaces 230,240 over the entire length. Further, the mounting members 231 and 241 and the frame members 232 and 242 are fixed to each other with screws or the like to form the frame body 20. Finally, insert the caps 235, 245 into the respective insertion holes 237, 247, and cover the
246 is filled and sealed.

As described above, the frame body 20 is installed between the wall surfaces 230 and 240, and the sliding door device 20 together with the sliding doors 31, 32 and 33 inside the frame body.
B is configured. In such a sliding door device 20B, the mounting member
231,241 together with multiple screws 239, through each through hole 237,247
249 can be hit, and there is no need to lift the inner frame 200 unlike the sliding door device 10A described above, and there is an effect that the fixing can be reliably performed. In addition, each insertion hole 237,247
Is sealed with caps 235, 245, and each is accommodated in a series of concave grooves 238, 248 and covered with a series of covers 236, 246, so that the appearance can be improved.

However, in such a sliding door device 20B, it is necessary to provide caps 235, 245 in the individual insertion holes 237, 247 for sealing, or to form concave grooves 238, 248 for aesthetics, and separately cover them with covers 236, 246. For example, there are problems such as a complicated structure, an increase in the number of parts, complicated work and an increase in cost.

In FIG. 12, frame members 311, 321, 331 of sliding doors 31, 32, 33 have watertight projections 3 extending vertically.
19,328,329,338 are formed. Each watertight projection 319, 32
Each of 8,329,338 is formed in a rib shape integrally extended from the frame members 311,321,331, and the tip is rounded.

When the sliding doors 31, 32, 33 are completely closed, the watertight projections 319 of the sliding door 31 and the watertight projections 3
28, and the watertight projection 329 of the sliding door 32 and the watertight projection 338 of the sliding door 33 are in close contact with each other to ensure the watertightness of the gap between them. One of the close ends is covered with a cushioning sealing material made of rubber or plastic to enhance the sealing performance at the time of close contact.

(Third Conventional Example) FIG. 14 shows a sliding door device 10C as a third conventional example. In the figure, the basic configuration of each sliding door 31, 32, 33 and the frame body 20 (frame members 311, 321, 33
1, the plate members 312, 322, 332, the upper frame 21, the lower frame 22, and the vertical frames 23, 24) are the same as those of the above-described sliding door device 10A (first conventional example).
In order to fix the frame 20, any of the above-described sliding door devices 10A and 10B is appropriately adopted. The support structure of each of the sliding doors 31, 32, 33 will be described below.

In the sliding door device 10C, three guide rails 215 corresponding to each of the sliding doors 31, 32, 33 are provided on the lower surface of the upper frame 21.
Are formed. Each guide rail 215 has a J-shaped cross section, and an upper curved lower edge serves as a rail function. Each sliding door 31, 32, 33 is made of frame material 311,
There are plate-shaped hanging parts 317, 327, 337 on the upper side of 321,331, and a pulley 40 is attached to each of them. Pulley 40 for each sliding door 31, 32, 33
Are engaged with the corresponding guide rails 215 to suspend and support the sliding doors 31, 32, 33, respectively, and allow the sliding doors 31, 32, 33 to move by rolling.

A lower recess 225 is formed in the lower frame 22 along the outside of the sliding door 31, and a downward recess 226 is formed immediately below the sliding door 32. The sliding door 31 is provided with a lower edge sealing material 315 over the entire length of the lower edge. The leading edge of the lower edge seal member 315 is inserted into the concave portion 225, thereby forming a watertight structure for the lower portion of the sliding door 31. The sliding door 33 is provided with a lower edge sealing material 336 over the entire length of the lower edge. The leading edge of the lower edge sealing member 336 is inserted into the recess 226, thereby forming a watertight structure for the lower portion of the sliding door 33.

The sliding door 32 is provided with a pair of lower edge sealing materials 325 and 326 over the entire length of the lower edge. The leading edge of the lower edge sealing member 325 is in close contact with the lower surface of the lower edge sealing material 315 of the sliding door 31. The leading edge of the lower edge seal member 326 is sliding door 3.
3. The lower edge sealing member 336 is closely contacted along the upper surface. This forms a watertight structure for the lower part of the sliding door 32.

As shown in FIG. 15, in the sliding door apparatus 10C, the height of the upper suspension structure of each of the sliding doors 31, 32, 33 can be adjusted. In the figure, the hanging parts 317, 327 of each sliding door 31, 32, 33,
An insertion hole 42 is formed in 337, and a screw 41 is inserted into the insertion hole 42, and the shaft of the pulley 40 is fixed by tightening the screw 41. The insertion hole 42 is a long hole that extends diagonally,
By shifting the position of 41 in the horizontal direction, the vertical height of the axis of the pulley 40 can be changed from the highest PH to the lowest PL.

Such a structure for adjusting the suspended height of each of the sliding doors 31, 32, 33 can be used to adjust the mutual height of each of the sliding doors 31, 32, 33 supported by the frame 20 when the frame 20 is installed. Is used for the inclination of. As shown in FIG. 16, in the frame body 20, the installed frame body 20 is often distorted into a parallelogram instead of an accurate square due to an inclined wall surface to be installed.

In such a case, even if the upper frame 21 and the lower frame 22 of the frame body 20 remain horizontal, the vertical frames 23 and 24 are inclined. Here, if the pulleys 40 of the sliding doors 31, 32, 33 are set to the same height as usual, the upper and lower edges of each sliding door may be horizontal and parallel to the upper frame 21 and the lower frame 22, but each sliding door remains vertical. A gap is created between the side edge of the vertical frame 23 and the vertical frames 23 and 24 of the inclined frame body 20.

To solve such a problem, for each of the sliding doors 31, 32 and 33, one pulley 40 is raised and the other is lowered, and the upper and lower edges of each sliding door are inclined to the upper frame 21 and the lower frame 22. The side edges of each sliding door can be set parallel to the vertical frames 23 and 24 of the frame 20. By doing so, it is possible to avoid the generation of a gap between the side edge of each sliding door and the vertical frames 23, 24 of the inclined frame body 20.

The upper and lower edges of each sliding door are connected to an upper frame 21 and a lower frame.
Since each of the structures 22 can tolerate vertical displacement, there is no problem such as generation of a gap due to tilting. Also, in order to perform an operation of tightening the screw 41 of each of the sliding doors 31, 32, 33,
Each of the three guide rails 215 of the upper frame 21 is formed with a circular or similar operation hole 216. Of these, a cap 217 is inserted into the operation hole 216 on the side of the sliding door 33 facing the outside so as not to impair the appearance.

[0034]

The above-described conventional sliding door devices 10A, 10B, and 10C have the following problems, respectively, and a structure capable of solving these problems has been desired.

(Problem of Wall Mounting Part) First, there is a problem of a wall mounting part. First, the sliding door device 10A (first
In the conventional example, one mounting member 241 is fixed through three or more points, whereas the other mounting member 231 is fixed through two upper and lower points, which is not sufficient in strength. In addition, it is necessary to lift the inner frame body 200 in fixing the lower portion of the mounting member 231 through therethrough, so that there is a problem that workability is not good.

On the other hand, in the sliding door device 10B (second conventional example), the frame members 2
Insertion holes 237,247 are formed in 32,242. This allows
Both of the mounting members 231 and 241 can be fixed to penetrate at three or more places. Also, when installing the inner frame 200
No need to lift up.

However, in the sliding door device 10B, each of the insertion holes 237, 2
Caps 235 and 245 are used to seal 47. Also,
In order to avoid a deterioration in aesthetic appearance due to a large number of caps 235, 245 being arranged, the insertion holes 237, 247 are arranged in the recesses 238, 248, and these are covered by covers 236, 246 collectively. As described above, in the sliding door device 10B, a plurality of perforations are required, and the caps 235, 245 and the covers 236, 246 are required.
And so on, resulting in an increase in parts management and manufacturing costs.

As described above, for the wall mounting portion,
Improvement in strength and workability and improvement in aesthetics and reduction in the number of parts have not been solved as conflicting conditions.

(Problem of Building Frame) Third, there is a problem of building a frame. In the above-described sliding door device 10C (third conventional example), the suspended state of each of the sliding doors 31, 32, 33 is adjusted with respect to the inclination of the wall surfaces 230, 240 and the accompanying inclination of the vertical frames 23, 24, respectively. Was tilted. Then, in order to tilt each sliding door, a structure in which the mounting height of each pulley 40 can be adjusted has been adopted.

However, in the conventional adjustment, each of the sliding doors 31, 32, 33
It is necessary to make adjustments for each of them, and if the number of sliding doors further increases, the work becomes more complicated. In addition, it is necessary to form an operation hole 216 used for performing adjustment on the guide rail 215 of the upper frame 21, and a cap 217 is used as appropriate so as not to impair the aesthetic appearance. There was a problem of inviting.

(Problem of waterproofing between sliding doors) Secondly, there is a problem of waterproofing between sliding doors. In the above-described sliding door device 10A (first conventional example) and sliding door device 10B (second conventional example), in order to ensure watertightness when the sliding doors 31, 32, and 33 are closed, respectively, each frame member is secured. Rib-shaped watertight projections 319, 328, 329, 338 extending vertically are formed integrally with 311, 321, 331, respectively.

Here, these watertight projections 319, 328, 329,
338 does not need to be made of the same material as the frame members 311,321,331 in consideration of strength and the like. However, for simplification of the manufacturing process, it is desirable to form it integrally with the frame material. From such a background, conventionally, the watertight projection is formed of the same expensive material as the frame material, such as an aluminum alloy. That is, the simplification of the manufacturing process and the reduction of the material cost cannot be solved as mutually contradictory conditions.

(Request for Sliding Door Device) Considering the above problems, the conditions required for a new sliding door device are as follows:
While securing the mounting strength, ensuring the installation adjustment performance, the waterproof performance between the sliding doors, etc., each part structure and manufacturing,
It can be said that the construction work is not complicated. An object of the present invention is to provide a sliding door device having a simple structure and good workability while improving performance such as mounting strength and installation adjustment performance.

[0044]

SUMMARY OF THE INVENTION According to the present invention, the vertical frame portion is adapted to cope with the inclination of the wall while using the vertical frame insertion hole, and the inclination can be adjusted particularly at the penetration fixed portion. By doing so, it is intended to secure the mounting strength and the mounting adjustment performance while simplifying the structure. Specifically, the following configuration is adopted.

The present invention is a sliding door device comprising a substantially rectangular frame body including a pair of vertical frames fixed to a wall surface, and a sliding door held in the frame body. An attachment member fixed to the wall surface, a frame member attached to the attachment member, and an intermediate member movably supported with respect to the frame member from a first state to a second state, The frame member has an insertion hole corresponding to a position where the mounting member is penetrated and fixed to the wall surface, and the intermediate member has a fixing operation hole at a position corresponding to the insertion hole when in the first state. ,
In the second state, a mounting fixing device is provided at a position corresponding to the insertion hole.

Here, it is preferable that the mounting and fixing device has a structure having a female screw hole formed in the intermediate member and a bolt screwed into the female screw hole to adjust the inclination of the frame member with respect to the mounting member. This bolt may be screwed into the female screw hole in advance at the manufacturing facility of the sliding door device, or may be screwed separately at the time of installation adjustment.

In such a configuration, installation is performed in the following procedure. First, with the intermediate member in the first state, the fixing operation holes and the insertion holes of the frame member are communicated with each other.
In this state, as in the above-described second conventional example, the mounting member is placed along the wall surface, the frame member is covered with the intermediate member, and the fixing member such as a screw or a nail is fixed to the mounting member through the communicating fixing operation hole and the insertion hole. Driving members. Thereby, the mounting member is fixed to the wall surface, and the inner frame member is temporarily fixed by the pair of mounting members on both sides.

In this state, there is a possibility that the mounting member is inclined according to the wall surface, and the frame member that is simply covered is also inclined according to the mounting member. Therefore, the inclination of the frame member is adjusted by the following operation to correct the vertical state.

That is, with the intermediate member in the second state, the respective mounting and fixing devices and the insertion holes of the frame member are arranged at corresponding positions such as on the same axis. Next, the bolt of the mounting and fixing device is screwed through the insertion hole, and the tip of the bolt is brought into contact with the mounting member (or the fixing member previously driven). Then, by appropriately adjusting the screwing amount of the bolt, the distance of the frame member to the mounting member is adjusted, thereby adjusting the inclination of the frame member.
For example, when the upper side of the frame member is inclined so as to approach the wall surface side, the frame member is separated from the wall surface by screwing a bolt of the mounting fixing device on the upper side of the intermediate member, and the vertical state can be adjusted. it can.

Therefore, in such a configuration, the fixing of the mounting member on each side can be made sufficiently strong by applying the fixing member by the insertion hole, and the installation adjustment performance can be secured by adjusting the inclination of the frame member by the bolt. At this time, in adjusting the installation, the conventional tilt adjusting structure for each sliding door can be omitted, thereby simplifying the structure, simplifying the manufacturing process, and simplifying the adjusting work for each sliding door. It becomes possible.

Further, the use of the intermediate member enables the same insertion hole to be used for the function of adjusting the inclination of the frame member and the fixing of the mounting member, eliminating the need for an insertion hole dedicated to adjusting the inclination. For this reason, it is possible to avoid complication of the manufacturing process due to an increase in the number of insertion holes and the caps thereof, and it is also possible to avoid a reduction in appearance. As described above, a sliding door structure having a simple structure and good workability can be obtained while improving performance such as mounting strength and construction adjustment performance.

In the present invention, the intermediate member is disposed inside the frame member over the entire length of the frame member and is movable along the longitudinal direction, and the end portion of the intermediate member has the end portion of the frame member in the second state. It is desirable that the shape does not protrude from the end. With such a configuration, the insertion holes and the fixing operation holes arranged in the longitudinal direction of the frame member and the fixing member can be collectively handled by one intermediate member, and efficient arrangement and operation can be achieved. I can do it.

In the present invention, a plurality of the insertion holes and the fixing operation holes are arranged along the longitudinal direction of the frame member and the intermediate member, and the mounting and fixing device is provided at the uppermost and lowermost ones of the insertion holes. It is desirable to be formed in two corresponding positions. With this configuration, it is possible to provide a configuration that is sufficient and minimum for application to any one of the upper and lower ends used when correcting the inclination of the frame member.

In the present invention, it is desirable that the female screw hole is constituted by an opening formed in the intermediate member and a nut joined to one side of the opening. With such a configuration, it is not necessary to perform threading or the like on the intermediate member for the mounting and fixing device, and the female screw hole can be easily formed.

In the present invention, the intermediate member has, on one surface, a pair of holding ribs continuous over the entire length of the intermediate member, and the holding rib is formed in an L-shaped cross section capable of holding the nut from both sides. Preferably, the nut is screwed into the bolt while being held in the holding rib, and the bolt is desirably inserted from the nut into the opening of the intermediate member.

With this configuration, the holding rib can be easily manufactured by, for example, drawing out the intermediate member, and the nut is held by the holding rib. By screwing the bolt to the nut and inserting the intermediate member, the nut and the bolt can be held in a predetermined form without the nut shifting along the holding rib. Therefore, the nut can be joined to the intermediate member without joining processing such as adhesion or welding.

In the present invention, a cover from the upper end to the lower end is attached to the frame material of the sliding door, and the cover is extended toward the adjacent sliding door and has a lip portion whose leading end contacts the adjacent sliding door. It is desirable to have. With this configuration, a rib-like portion integrally extending from the frame material as in the related art can be omitted, and expensive materials such as an aluminum alloy can be reduced. In addition, the cover at the end of the frame material is generally frequently used when hiding the assembling screws of the frame material, and the structure can be simplified by extending this and using it for the lip. it can.

The same insertion hole 60 can be shared by the inclination adjustment function of 242 and the fixing of the mounting members 231 and 241, and a dedicated insertion hole for inclination adjustment is not required. For this reason, it is possible to avoid complication of the manufacturing process due to the increase of the insertion holes 60 and the caps 61 thereof, and it is also possible to avoid a reduction in appearance.

In particular, the intermediate member 50 is mounted on the frame members 232 and 242 in advance, and by switching between the first position and the second position, the fixing function and the inclination adjusting function can be switched. Operation is easy. In addition, the bolts 53 and nuts 52 for adjusting the inclination are also mounted on the intermediate member 50 in advance, so that the operation of transport, installation and adjustment is easy.

The intermediate member 50 can be easily manufactured by drawing including the holding rib 501, and the frame members 232 and 242 can be easily manufactured by drawing including the supporting rib 51 for supporting the intermediate member 50. . Other necessary insertion holes 60, fixing operation holes 502, and openings 503 for female screw holes may be formed by simple boring, and the manufacturing process can be simplified.
