DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sash used for an entrance connecting an indoor room and an outdoor room.

[0002]

2. Description of the Related Art As shown in a typical example in FIG. 9, a conventional general sash employs a stepped watertight structure in order to provide watertight performance (raining performance). Specifically, the height is gradually increased from the outdoor side O toward the indoor side S, and a large watertight step H such as 80 mm is provided between the outdoor side O and the indoor side S. The step H prevents rainwater from entering from outside. Large water-tight steps due to such a step-water-tight structure, for example, such as nursing homes and hospitals, people who have impaired physical functions, have unstable walking, or are forced to act in a wheelchair In the case of a place, an entrance that connects the room with the outside such as a veranda or a common corridor is a major obstacle. In other words, if the step is large, there is a problem that the vehicle easily trips when passing over the sash, and there is a problem that it is difficult to pass the wheelchair.

[0003] For this reason, a sash for a doorway of a nursing home, a hospital, or the like may be a sash having a special structure in which a step is set to a minimum necessary range for, for example, a doorway of a sliding door, that is, a flat sash. It is becoming. Such a conventional flat sash is designed to be flat by using a watertight structure by a closed system instead of the watertightness due to the watertight step in the conventional general sash. Specifically, as shown in FIG. 10, a flexible airtight lip 21 is provided on the lower end surface of the sliding door 20, and the sliding door 22 of the sliding door 20 is moved up and down by operating a handle (not shown) so that the sliding door 20 is closed. The lower frame 23 can be moved up and down. When the sliding door 20 is run, the door wheel 22
Is lowered to float the sliding door 20 with respect to the lower frame 23. When the sliding door 20 is retracted and the sliding door 20 is lowered when the door is closed, the hermetic lip 21 is moved downward by the lower frame 23.
And tightly closed (as shown in the figure).

However, in the case of this closed type flat sash, there is a problem that the airtight lip 21 does not sufficiently seal the overlapping portion of the sliding door 20 and the fixed door 24, and there is a slight inundation therefrom. . Therefore, infiltration water is treated by using the hollow lower frame 23 as a hollow drainage channel. That is, a water passage hole (not shown) is provided in the lower frame 23 inside the doorway 25, and the infiltration water is guided from the water passage hole into the hollow inside of the lower frame 23. Water is drained to the drain G.

[0005] As described above, the conventional closed flat sash achieves high flatness at the entrance and exit and sufficient watertightness. However, moving the door wheel up and down greatly complicates its structure, and as a result, it is inevitable that the price will be extremely high as compared with a general sash. This imposes a heavy burden on nursing homes and hospitals that are operated with a limited budget, and is a factor that hinders access to nursing homes and hospitals that require the most flat entrance / exit structure.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and an object of the present invention is to provide a sash for an entrance which can realize flattening at lower cost.

[0007]

According to the present invention, a sash having a stepped watertight structure for providing watertightness based on a predetermined step is provided with a lower frame having a height of a doorway and a door stop. An upper step having a height difference is provided, and a rainfall part having a plurality of water holes is provided along the upper part, and a predetermined depth is provided below the rainfall part. Provision of a closed hollow drainage channel,
The structure is such that the rainwater that enters is guided to the hollow drainage channel through the drainage hole of the rainfall dropping part, and then discharged to the outside through the drainage pipe from the hollow drainage channel. The steps provide a watertight step required for the step watertight structure.

That is, in the sash according to the present invention, a minimum step which cannot be avoided due to a doorway and a door stop is given to the upper step, and the step by the upper step is assisted while the hollow drainage channel is formed. By making a large step due to the depth function as a main step for watertightness, a stepwise watertight structure is obtained, and the step for watertightness is generally provided in a direction opposite to the conventional one, that is, downward.

[0009] By forming the watertight step downward by the step mainly based on the depth of the hollow drainage channel, the watertight step is sufficiently secured to realize high watertightness.
The level difference between the indoor floor and the floor outside the room, such as a veranda or common corridor, is about the height of a doorway for a sliding door (usually around 15 mm), and a door stop for a door type. The height can be reduced to about the height (usually around 15 mm), and high flatness can be realized.

[0010] The present invention is further the sash as described above, provided with a partition within with water passing holes on the hollow drainage, so that partition the hollow drainage in the upper hollow portion and a lower hollow portion by partition therein .

According to this structure, the intermediate partition serves as a buffer, and the backflow from the hollow drainage channel can be more effectively prevented.
Higher watertightness can be realized. That is, the intermediate partition functions to reduce the momentum of the water flowing backward from the drainage ditch connected to the hollow drainage channel through the drainage pipe by the wind pressure of a strong wind such as a typhoon, thereby preventing the backflow water from entering the room. It can be more effectively prevented. In addition, the intermediate partition functions as a measure against fallen leaves and debris that enter through the water holes in the rainwater drop section. In other words, when dead leaves and garbage directly enter the deep hollow drainage channel, there is a problem of clogging of the waterway as described above, but if these are received by an intermediate partition at an intermediate depth position, Cleaning can be performed relatively easily.

In the present invention, the sash as described above is provided with a mounting receiver at a predetermined depth along the upper step.
A glazing member having a plurality of water holes is removably fitted and mounted on the mounting receiving portion to form a rainwater dropping portion.

[0013] This structure is to prevent falling leaves and dust entering through the water holes of the rainfall dropping section. That is, when the hollow drainage channel is clogged with dead leaves, dust, etc., the glazing member is removed so that dead leaves, dust, etc. can be collected from the hollow drainage channel.

In the present invention, the sash as described above is formed such that the width of the upper hollow portion is wider than the width of the lower hollow portion.

[0015] This structure also functions to buffer the backflow water in the same manner as described above. When the backflow water flows from the lower hollow portion on the upstream side to the upper hollow portion on the downstream side, the width of the backflow water increases. By expanding the flow path of the backflow water in the wide upper hollow portion, the backflow water functions to be weakened. As a result, it is possible to further effectively prevent the backflow water from entering the room.

In the present invention, a plurality of water holes of the intermediate partition are formed at predetermined intervals in the sash as described above, and each of the water holes does not overlap with each of the water holes of the rainfall dropping portion. ing.

As described above, if the water holes of the rainwater dropping portion and the water holes of the intermediate partition do not overlap each other, it is possible to considerably reduce falling leaves and dirt from entering the lower hollow portion. Therefore, the occurrence of clogging can be suppressed accordingly.

[0018]

Embodiments of the present invention will be described below. As shown in FIG. 4, the sash according to the first embodiment is of a single sliding type comprising two movable sliding doors 1, 1 and two fixed doors 2, 2. The lower frame 3, which is the main part,
As shown in FIGS. 1 to 3, a rainwater drop groove 6 is provided along an upper step portion 5 formed at substantially the same height as the door roller track 4.

The rainwater drop 6 has a width W of about 26 mm.
The depth D is formed to be about 13 mm, and also serves as a mounting receiving portion. In other words, a square groove-shaped glazing member 7 having water holes 7h (FIG. 2) at regular intervals is fitted into the rainwater drop groove 6, and the glazing member 7 forms a rainwater drop portion 8. The rainwater drop groove 6 also serves as an upper hollow portion 9 a of the hollow drainage channel 9. In other words, rainfall ditch 6
The bottom with water holes 9h formed at regular intervals is an intermediate partition 9s.
With the glazing member 7 and the intermediate partition 9s fitted therein, the openness of the glazing member 7 through the water passage hole 7h (FIG. 2) and the intermediate partition 9s through the water passage hole 9h is excluded, so that the entire structure is closed. An upper hollow portion 9a is formed. Although the water holes 7h of the glazing member 7 are also formed at regular intervals, the water holes 7h do not overlap with the water holes 9h of the intermediate partition 9s.

On the other hand, the lower hollow portion 9b of the hollow drainage channel 9
Rainwater drop groove 6, ie, upper hollow portion 9a, through water hole 9h
The other portion is formed in a sealed shape, and the width thereof is the same as that of the rainfall drain groove 6 except for a part that is partially enlarged, but has a depth of about 53 mm. A drain pipe P is connected to the lower hollow portion 9b at one or more locations.

As a result, the upper hollow portion 9a and the lower hollow portion 9
Step H due to the depth of the hollow drainage channel 9 consisting of b: about 66 m
The total step height Ht = about 81 mm, which is obtained by adding an auxiliary step about 15 mm provided by the height of the rainwater drop groove 6 (upper hollow part 9 a) and the upper step part 5 adjacent to the m, is given as the watertight step. That is, for example, rainwater that has entered from the veranda B across the doorway 4 passes through the water holes 7h of the glazing member 7, enters the upper hollow portion 9a, and further passes through the water holes 9h of the upper hollow portion 9a. The water is guided to the lower hollow portion 9b, and finally drained to the drain G of the veranda B by the drain pipe P.
In order for rainwater to enter, it is necessary to substantially climb over the watertight step Ht, and thus the watertight step Ht is given watertightness. On the other hand, the step between the outdoor side and the indoor side can be limited only to the step formed by the upper step portion 5 which is about the height of the doorway 4 and high flatness can be realized.

Here, when the present sash is used, the drain groove of the veranda is provided close to the sash, for the following reason. That is, the high flatness as described above is for facilitating, for example, traffic when going out to a veranda in a wheelchair, but for further enhancing safety when going out to a veranda using such a wheelchair. . In other words, in the case of a general structure, the drainage groove is provided at the tip of the veranda, and the entire veranda is gently inclined toward the drainage groove. Unexpected momentum can cause a wheelchair, which can result in an accident. Therefore, by providing the drainage groove close to the sash, the veranda is inclined in the opposite direction, and the possibility of such an accident is eliminated.

The second embodiment is a modification of the single-drawing type sash similar to the first embodiment, and as shown in FIG. It has a part 13. The mounting receiving portion 13 has a width of about 26 mm and a depth of about 13 mm, into which a glazing member 14 having water holes 14h at regular intervals is fitted and fitted similarly to the glazing member 7 of the first embodiment. The glazing member 14 is mounted, and a rainwater dropping portion 15 is formed.

A rainwater dropping portion 15 is provided below the mounting receiving portion 13.
A closed hollow drainage channel 16 is provided in communication with the hollow drainage passage 16. The hollow drainage channel 16 includes an upper hollow portion 16a and a lower hollow portion 16b having a narrow lateral width, and has a depth of about 60 mm as a whole. At the boundary between the upper hollow portion 16a and the lower hollow portion 16b, an intermediate partition 17 having water holes 17h at regular intervals is provided similarly to the intermediate partition 9s in the first embodiment. As in the first embodiment, the position of the water passage hole 17h is not overlapped with the water passage hole 14h of the glazing member 14. In FIG. 5, for convenience of explanation, both the water passage hole 14h and the water passage hole 17h are temporarily shown. However, since the positional relationship does not overlap as described above, one of them does not actually appear in the figure. Becomes

Therefore, also in the case of the sash of this example, the total height Ht = approximately 7 which is obtained by adding the height H of the upper drain 12 to the height H of approximately 60 mm to the height H of the hollow drainage channel 16 and approximately 15 mm.
5 mm is a step for watertightness.

The third embodiment is an example of a sliding type, in which a lower frame 30 has one sliding door 3 as shown in FIGS.
It has a door roller track 32a for 1a and a door roller track 32b for the other sliding door 31b, and a mounting receiving portion 33 is provided between the door roller track 32a and the door roller track 32b.

The mounting receiving portion 33 is formed wider than the mounting receiving portion 13 of the second embodiment. Also, a glazing member 35 mounted thereon to form a rainwater dropping portion 34
Has a sealing material holding portion 36. The seal material holding portion 36 is for holding the seal material 37 in contact with the sliding door 31a, and is used for the door roller tracks 32a to 32b.
It is formed at almost the same height as. Further, the sealing material holding portion 36 is provided at a position where the left side divided by this is substantially the same as the width of the glazing member 14 of the second embodiment, and the length thereof is set to a length substantially corresponding to the width of the sliding door 31a. ing. That is, the sealing material holding portion 36 is not provided over the entire length of the glazing member 35, but is provided on the sliding door 3.
When the sealing member 37 is closed, the sliding door 31a is closed.
Are provided in a range that abuts the contact.

The glazing member 35 has two types of water holes 35h and 35H (FIG. 7). That is, a water passage hole 35h is formed in a portion along the seal material holding portion 36, and a water passage hole 35H larger than the water flow hole 35h is formed in a portion without the seal material holding portion 36. As a result, in the case of the present embodiment, the seal material holding portion 36 along the water passage hole 35h forms a part of the upper step portion 38, and the door wheel track 32b along the water passage hole 35H becomes the remaining portion of the upper step portion 38. Will be formed.

As in the second embodiment, a hollow drainage channel 39 having an overall depth of about 60 mm is provided below the mounting receiving portion 33 so as to communicate with the rainwater dropping portion 34. Similarly, the drainage channel 39 is divided into a wide upper hollow portion 39a and a narrow lower hollow portion 39b by an intermediate partition 40 having water holes 40h at regular intervals. Also in this case, the step H due to the depth of the hollow drainage channel 39 is about 6
The total step height Ht = about 75 mm obtained by adding the height of the upper step section 38 to about 15 mm to 0 mm is the watertight step.

FIG. 8 shows a sash according to a fourth embodiment, which is an example of a door type in which a door panel 50 is rotated. This case is also basically the same as the second embodiment, but
The upper step 52 of the lower frame 51 is
Is formed at a height of about 15 mm for a door stop, and a mounting receiving portion 54 having substantially the same size as that of the second embodiment is formed along the upper step 52, and a water passage hole 55h is formed there.
By fitting and mounting a glazing member 55 having

As in the case of the second embodiment, a hollow drainage channel 57 having an overall depth of about 60 mm is provided below the mounting receiving portion 54 so as to communicate with the rainfall portion 56,
Similarly, the hollow drainage channel 57 has a wide upper hollow portion 57 formed by an intermediate partition 58 having water holes 58h at regular intervals.
a and a lower hollow portion 57b having a narrow lateral width. Therefore, also in this case, the step H due to the depth of the hollow drainage channel 57 is formed.
The total step height Ht = about 75 mm obtained by adding the height of the upper step 52 to about 15 mm to about 60 mm is the watertight step.

[0032]

As described above, according to the present invention, in a sash having a step watertight structure for achieving watertightness based on a predetermined step, the step for watertightness is directed downward by a step mainly based on the depth of the hollow drainage channel. Since it is formed, a sufficient flatness can be ensured and a high flatness can be realized, and the flattening can be realized at a relatively low cost because the structure is not so complicated.
