[Problems to be solved by the device]

 By the way, in the above 180 ° open door device, airtightness and watertightness are required so as to effectively carry out cooling and heating and block external noise. It is necessary to make the gap between 21 and the floor 1 (frame 11) as small as possible.

However, the gap G between the open door 21 and the floor surface 1 is. Floor 1 is often made of concrete, etc., and it is difficult to achieve flatness. The reason why it is necessary to prevent dust (pebbles, etc.) on the floor surface 1 from being caught between the floor surface 1 and the opening door 21 in order to ensure smooth opening and closing of the opening door 21 Therefore, it is difficult to make it narrow, and it is difficult to achieve airtightness.

[0006] Therefore, as one measure to eliminate such inconvenience, it is conceivable to provide an airtight material (not shown) on the lower frame 22 of the opening door 21 to close the gap G. However, in this case, the airtight material is rubbed against the floor surface 1 (generally, the surface is rough) every time the opening door 21 is opened / closed, and the airtight material is worn early to function as the airtight material. It will be gone.

In view of the above circumstances, an object of the present invention is to provide a door device capable of improving airtightness and watertightness while ensuring smooth opening and closing of the door.

[0008]

[Means for Solving the Problems]

 The door device according to the present invention has a frame body that forms an opening that stands upright on the floor surface, has a gap with the floor surface in the frame body, and is rotatable within a predetermined angle range about the standing axis line. A door mounted on the floor, and a door device configured to open and close the opening of the frame by opening and closing the door, an airtight member protruding downward is provided at the lower end of the door, and The surface is provided with an engaging projection that comes into contact with the airtight member when the door is closed and is out of contact with the airtight member when the door is opened.

[0009]

[Action]

 In the present invention having the above-described structure, when the door is closed, the gap between the door and the floor surface is closed by the airtight member and the engaging protrusion that are in contact with each other. On the other hand, except when the door is closed, the airtight member is separated from the floor surface without contacting the engaging protrusion. Therefore, even if the door is opened and closed, the airtight member does not rub against the floor surface, and an excessive load does not act.

Therefore, the door can be opened and closed smoothly, and the airtightness and the watertightness can be improved when the door is closed.

[0011]

Embodiment An embodiment of the present invention will be described with reference to the drawings. The door device according to the present invention is applied to a 180 ° opening door device for stores, and as shown in FIG. 1, a frame body 11, a door (opening doors 21 and 21), an airtight member (31), an engaging convex portion. (41) is included. The same components as those shown in FIG. 7 are designated by the same reference numerals, and the description thereof will be omitted or simplified.

Here, an airtight member protruding downward is provided at a lower end portion (lower frame 22 in this embodiment) of each opening door 21. In this embodiment, the airtight member is composed of an attachment 31 with a tight material. As shown in FIG. 2, the attachment 31 is composed of a main body 32 detachably attached to the lower frame 22 of the open door 21 and two tight members 33, 33 attached to the main body 32. There is. Each tight member 33 is mounted on the main body 32 at a predetermined distance.

Further, each tight member 33 is made of an elastic member and is configured to contact the engaging convex portion (41) by utilizing its own elastic restoring force when the opening door 21 is closed. More specifically, each tight member 33 is attached to the main body 32 so as to deform within the range where it is not crushed when the opening door 21 is closed and to come into close contact with the engaging convex portion (41).

In particular, in this embodiment, in order to further improve the airtightness and the like, the attachments with the tight material having the same structure as the attachment 31 are also attached to the vertical frames 23 and 24 and the upper frame 25 of each opening door 21. 31A, 31C, 31B are provided. As shown in FIGS. 3 and 4, the attachment 31A (31B) is deformed within a range in which the tight material 33A (33B) is not crushed when the door 21 is closed and the vertical frame 13 (upper frame 15) is deformed. It is attached to the vertical frame 23 (upper frame 25) of the door 21 so as to be in close contact with it. Similarly, the attachment 31C is attached to the vertical frame 24 of each door 21 so as to close the gap between the doors 21 and 21 when the opening doors 21 and 21 are closed.

Further, the engaging convex portion is formed on the floor surface 1 so as to be in contact with the airtight member (31) when the opening door 21 is closed and not in contact with the airtight member (31) when the opening door 21 is opened. ing. In the present embodiment, the engaging projection is composed of the engaging rail 41 and the like provided on the floor surface 1 so as to be parallel to the upper frame 15 of the frame body 11. The engagement rail 41 is made of stainless steel, and its surface is formed so as to have required flatness and surface roughness. Further, the step between the upper surface 42 of the engagement rail 41 and the floor surface 1 is, as shown in FIG. 2, a height that is in close contact with the attachment 31 on the side of the opening door 21 and does not cause a pedestrian to trip.

In particular, in the present embodiment, the engaging protrusion is configured to include not only the engaging rail 41 but also the hinge portion 27 so that the airtightness and the like can be further improved. Therefore, as shown in FIG. 5, the engaging rail 41 and the main body 28 of the hinge portion 27 are connected so that their upper surfaces 42 and 28f have the same height.

Next, the operation will be described. When the opening doors 21 and 21 are closed, the tight material 33 of each attachment 31 provided on the doors 21 and 21 comes into close contact with the engaging protrusions (42, 28f) on the floor surface 1 side. Similarly, the tight material 33A (33B) of each attachment 31A (31B) is in close contact with the vertical frame 13 (upper frame 15) of the frame body 1. In addition, the attachments 31C and 31C also come into close contact with each other. As a result, the gaps between the opening doors 21 and 21, between the opening doors 21 and the floor surface 1, and between the opening doors 21 and the frame body 11 are closed, and airtightness and watertightness are dramatically improved. .. In addition, fireproofness and crime prevention also improve with the improvement of airtightness.

On the other hand, when the opening doors 21 and 21 are opened from the closed state, the contact state between the tight material 33 of the attachment 31 and the engaging convex portions (42, 28f) is released and the non-contact state is established. The opening doors 21 and 21 can be smoothly opened without an excessive load acting on the doors 21 and 21.

Therefore, according to this embodiment, an attachment 31 with a tight material protruding downward is provided on the lower frame 22 of each opening door 21, and the attachment 31 is attached to the floor surface 1 when the opening doors 21 and 21 are closed. Since the engaging convex portions (the upper surface 42 of the engaging rail 41 and the upper surface 28f of the hinge portion 27) that come into contact with the tight material 33 and are in a non-contact state with the tight material 33 are provided, it is smooth. It is possible to improve airtightness, watertightness, fireproofness, etc. while ensuring the opening and closing of the opening doors 21, 21.

Further, since the vertical frames 23, 24 and the upper frame 25 other than the lower frame 22 of the opening door 21 are also equipped with the attachments 31A, 31C, 31B with the titer members to close the respective gaps, it is further improved. Airtightness, watertightness, fireproofing, etc. can be improved.

Further, since the airtight member is composed of the attachment 31 with the tight material, the mounting becomes easy.

Further, since the attachment 31 has a double airtight structure in which the two tight members 33, 33 are attached to the main body 32 (similarly to the attachments 31A, 31B, 31C), the airtightness, watertightness and It is possible to improve fire resistance and the like. Further, an air layer (heat retaining layer) is formed between the tight members (for example, the tight members 33, 33) when the opening doors 21 and 21 are closed, so that cooling and heating can be performed more effectively.

Further, since the engaging convex portion is composed of the stainless engaging rail 41 and the like, it is possible to maintain the flatness and the surface roughness at a constant level for a long period of time without rusting. Therefore, even if the tight material comes into contact with the closed material, the tight material does not wear off, and the airtightness, watertightness, fireproofness, etc. can be improved more effectively over a long period of time.

Further, since the engaging rail 41 and the hinge portion 27 are connected so that the respective upper surfaces 42 and 28f have the same height, the engaging convex portion is formed, so that the door 21 and the floor are completely opened. The gap between the surfaces 1 can be closed, and the airtightness, watertightness, fire resistance, etc. can be dramatically improved.

Furthermore, since the height difference between the upper surface 42 of the engaging rail 41 and the floor surface 1 is selected so that the pedestrian does not trip, the pedestrian safety is ensured.

As shown by the chain double-dashed line in FIG. 2, gently inclined surfaces 45, 45 may be provided on both sides of the engagement rail 41. With this configuration, it is possible to further secure pedestrian safety. In this case, the inclined surfaces 45, 45 may be formed integrally with the engagement rail 41. Moreover, you may provide separately.

Further, although the present door device is applied to a 180 ° opening door device for stores, it may be applied to other door devices (for example, a single opening door device).
