[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door type packing system, and more particularly, to a sliding door type packing system for sealing a space, such as a studio or a sterile room, where airtightness is required.

[0002]

2. Description of the Related Art There are many spaces, such as music studios, sterile rooms, and rooms that handle radiation, which are shielded from the outside and require airtightness. Depends greatly on As such a door in a room where airtightness is required, a hinged door that shuts air by rotating a door plate around a hinge and closely contacting a door frame is often used. If a hinged door cannot be installed, use a sliding door,
Sliding doors are unsatisfactory in performance because it is difficult to adhere the door plate to the door frame.

[0003]

In the case of a sliding door, the door plate has high adhesion in both the horizontal direction where the door frame and the edge of the door plate abut and the vertical direction where the door frame and the floor abut. Is required.

[0004] However, in the case of a usual sliding door type door, since the door plate slides in the horizontal direction, it is difficult to improve the adhesion in the vertical direction, that is, between the door plate and the floor surface.
SUMMARY OF THE INVENTION An object of the present invention is to provide a sliding door type packing system which can ensure high adhesion and blocking performance with a simple structure.

[0005]

In order to solve the above-mentioned problems, the present invention relates to a sliding door type packing system, wherein a door frame portion, a door plate portion connected to the door frame portion, and the same vertical plane as the door frame portion are provided. The door plate is slid horizontally at a position higher than the door frame above, and the door plate is moved obliquely downward with respect to the traveling direction on the vertical plane immediately before the door plate comes into contact with the door frame. A door plate portion moving mechanism, wherein the door frame portion has a plurality of door frame side contact portions having a predetermined width in a direction substantially perpendicular to a plane on which the door plate portion moving mechanism moves the door plate portion. And the plurality of door frame portion-side contact surfaces are formed continuously to form a first continuous contact portion, and the door plate portions are each formed on the door frame portion-side contact surface. And the door plate moving mechanism moves the door plate. A plurality of door plate portion-side contact surfaces having a predetermined width in a direction substantially perpendicular to the plurality of door plate portion-side contact surfaces are formed continuously to form a second continuous contact portion. The first continuous contact portion and the second continuous contact portion each have a predetermined width in a direction substantially perpendicular to a plane on which the door plate moving mechanism moves the door plate. With this configuration, it is possible to form a sealed state even if they abut against each other in a state of being shifted in the substantially vertical direction. According to the present invention, when the sliding door is closed, the door plate portion approaches while sliding horizontally in the direction of the door frame portion, and moves while falling obliquely downward with respect to the traveling direction immediately before contacting the door frame portion. As a result, the first continuous contact portion on the door frame portion side and the second continuous contact portion on the door plate side come into contact with each other, so that both the horizontal and vertical directions are securely adhered to each other, and high blocking performance is achieved. Is achieved. Here, since the first continuous contact surface and the second continuous contact portion each have a predetermined width in a direction perpendicular to the surface on which the door plate portion moves, the first continuous contact surface and the second continuous contact portion have the first width within the range of the width. If the continuous contact portion and the second continuous contact portion are in contact with each other, a sealed state can be formed even if the positions of the door plate portion and the door frame portion are shifted in the substantially vertical direction. .

[0006] The invention described in claim 2 is the invention according to claim 1.
In the sliding door type packing system according to the above, the plurality of door frame side contact surfaces are oblique abutment surfaces formed substantially perpendicular to the oblique lower part where the door plate moving mechanism moves the door plate. The plurality of door plate-side contact surfaces have an oblique contact surface that contacts an oblique contact surface provided on the door frame portion. This allows the door frame and the door plate to adhere to each other without friction. According to a third aspect of the present invention, in the sliding door type packing system according to the first or second aspect, one of the first continuous contact portion and the second continuous contact portion is provided. An integrated rubber packing is attached, and the other of the first continuous contact portion or the second continuous contact portion is attached to a sword member that contacts the rubber packing. Therefore, the sword tip member appropriately bites into the rubber packing, so that the sealing performance is further improved.

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. First, a basic structure of a sliding door type packing system according to the present invention will be described with reference to FIGS. FIG. 1 is a diagram showing a connection relationship between a door frame portion and a door plate portion, and FIGS. 2 and 3 are diagrams showing structures of a door frame portion and a door plate portion, respectively.

As shown in FIG. 1, in the sliding door type packing system according to the present invention, the door frame portion 10 and the door plate portion 20 are in close contact with each other, so that the blocking performance is ensured. Actually, the door frame 10 and the door plate 20 are installed as doors at the entrance of a space such as a studio. The door plate portion 20 is provided so as to be slidable in a direction substantially horizontal to the ground as shown in the drawing, and slides in the door frame direction I to be closed by being in close contact with the door frame portion 10. The door frame portion 10 and the door plate portion 20 slide at positions that coincide in the width direction III (on the same vertical plane). In addition, the door plate part 20 has a structure which slides in the door frame direction I at a position several mm higher than the door frame part 10 in the vertical direction II.

The door frame 10 and the door plate 20 have a structure as shown in FIGS. 2 and 3, respectively. That is, as shown in FIG. 2, the door frame 10 is provided with an L-shaped joint 100 inside the upper side 1 and the side 2 thereof.
0 has a horizontal contact surface 13a, a vertical contact surface 14a, and an L-shaped side contact surface 19a. The horizontal contact surface 13a
An inclined contact surface 12a inclined at about 45 degrees continues to the left end of the vertical contact surface 1a.
1a is extended. An inclined contact surface 15a inclined at about 45 degrees extends from the vertical contact surface 14a, and a narrow horizontal contact surface 16a is formed from the lower end thereof.
A vertical contact surface 17a is provided on the inside of the left side of the door frame 10.
Is formed, and a horizontal contact surface 18a is formed inside the lower side. The L-shaped joint 100 and the vertical and horizontal contact surfaces 17a and 18a form a passage opening S through which a person passes.

On the other hand, as shown in FIG. 3, an L-shaped outer edge portion 110 is formed in the door plate portion 20, and the inside of the outer edge portion is widely cut into a rectangular shape, and a horizontal portion is formed on the upper side. An abutment surface 13b, a vertical abutment surface 14b on a side portion, and a flat closing portion 200 occupying most of the door plate portion 20 and closing the passage opening S of the door frame portion 10 are formed. The contact surface 19b is formed. The horizontal contact surface 13b is
A vertical contact surface 11b extends from the inclined contact surface 12b inclined by about 45 degrees. A vertical contact surface 17b extends downward from the inclined contact surface 12b, and a horizontal contact surface 18b is formed horizontally from a lower end thereof. Further, an inclined contact surface 15b inclined at about 45 degrees is formed on the left side of the horizontal contact surface 18b, and the inclined contact surface 15b is connected to the horizontal contact surface 16b. The respective contact surfaces 12b to 15b, 17b to 18b of the door plate portion 20 are respectively corresponding to the respective contact surfaces 12a to 15a, 17 of the door frame portion 10.
a to 18a are tightly closed. If the above-mentioned contact surfaces are in close contact with each other, even if the other contact surfaces 11a,
11b, 16a, 16b, 19a, 19b, 20a, 2
The sealing between the door plate portion 20 and the door frame portion 10 can be realized without the close contact of Ob.

Next, the closing operation of the door plate will be described with reference to FIG.
5 will be described. FIG. 4 shows an example of the door plate moving mechanism. In FIG. 4, the door plate 20 is moved in the sliding direction I by the moving mechanism 30 with respect to the door frame 10 fixed to a part of the room. The moving mechanism 30 has a rail 32 provided above the door plate 20 and running wheels 31 rolling on the rail 32. The rail 32 is partially cut, and inclined portions 32a, 32a inclined at 45 degrees.
Are provided with the depressions 32b, 32b. The door plate portion 20 is suspended by running wheels 31a, 31a and moves in the sliding direction I. Here, running wheels 31
When a and 31a reach the positions of the inclined portions 32a and 32a of the rail 32, they fall downward by approximately 45 degrees along the inclination of the inclined portions. Along with this, the door plate part 20 moves downward by approximately 45 degrees and comes into close contact with the door frame part 10. Door frame 1
0 contact surfaces 12a and 15b and the contact surface 12 of the door plate 20.
The reason why b and 15b are formed at an angle of approximately 45 degrees in the horizontal and vertical directions as described above is to eliminate the gap between the door frame 10 and the door plate 20 due to the fall of the door plate 20. Further, by forming in this manner, any portion of the door plate is brought into close contact with the door without friction. The opening operation of the door plate portion 20 is performed, for example, by pulling the door plate portion 20 upward by approximately 45 degrees.

FIG. 5 shows another example of the door plate moving mechanism. FIG.
The door plate moving mechanism 40 shown in FIG.
a, 41b move, and the depression 4 provided in the traveling path 42
When the wheels 41a and 41b fall on 2a and 42b, the door plate part 20 falls and moves downward by approximately 45 degrees. The dents 42a and 42b are slid downward by approximately 45 degrees as shown in the figure, and then fitted and fixed in the dents. Therefore, as in the case of the moving mechanism shown in FIG.
And high degree of close contact.

In any of FIGS. 4 and 5, the contact surfaces of the door frame and the door plate do not abut each other until the door plate 20 falls obliquely downward, so that there is no frictional relationship. There is no fear.

In the above description, the door plate portion 20 moves obliquely downward by utilizing its own weight (gravity). In the case of a normal music studio, etc., the door plate ranges from several tens of kilograms to hundreds of tens of kilograms, so it is possible to achieve sufficient close contact only with its own weight, but of course, using electric energy or hydraulic pressure, etc. Further, the structure may be made to adhere more strongly.

In the above description, two examples of the mechanism for moving the door plate have been described. However, the mechanism is not limited to these modes as long as it is a mechanism for moving the door plate approximately 45 degrees downward.
The mechanism for opening the door plate once closed includes, for example, a method using a handle using a lever, a method of pulling back with a wire, a method of moving the door plate by changing the inclination angle of the rail itself for moving the door plate, and the like. Although a method is conceivable, any method may be used in the present invention.

Next, a mechanism for bringing the door frame portion 10 and the door plate portion 20 into close contact will be described with reference to FIGS. FIG. 6 shows a case where a rubber packing and a sword point are used as the close contact mechanism. As shown in FIG. 6, a rubber packing 50 is adhered on the contact surface of the door frame 10. On the other hand, a sword point 60 is provided on the corresponding contact surface of the door plate portion 20 so as to contact the rubber packing 50 substantially on the center line in the width direction. Therefore, the door plate 20
8 comes into contact with the door frame portion 10, as shown in the cross-sectional view of FIG.
The barrier properties are improved.

The rubber packing 50 can be easily manufactured by cutting the center of one rubber plate having a constant width as shown in FIG. Rubber packing is often used to enhance adhesion, but normal rubber packing, especially for doors, is often made of a combination of short packings, and is connected to any part of the contact surface. Since the eyes are formed, there is a disadvantage that the adhesion at the joints is reduced. However, the rubber packing in the present invention is
As shown in Fig. 7, since it is made integrally by cutting the center of one rubber plate, there is no seam at the contact surface with the sword tip as shown in Fig. 6, and high adhesion is realized. it can.

Even when the door plate portion 20 is slightly shifted in the width direction III and is joined to the door frame portion 20, the surface where the rubber packing comes into contact with the sword tip has a constant width. The rubber packing may be abutted at any position within the range. For this reason, even if there is a slight displacement in the width direction at the connection position between the door plate portion and the door frame portion, the adhesion does not decrease and the adjustment of the connection position in the width direction becomes unnecessary. In addition, as this adhesion mechanism, in addition to the combination of the rubber packing and the sword tip described above, when only the rubber packing is used without providing the sword tip on the door plate part, when the rubber packing is bonded to the door plate part and the rubber packings come into contact with each other. And so on. Also, the number of sword tips may be increased.

As shown in FIG. 8B, a concave portion 51 having a constant depth is formed in the door frame portion 10 and a convex portion 61 is formed in the door plate portion 20.
If the concave portion 51 and the convex portion 61 are deeply engaged with each other when the door plate is closed, the degree of connection is increased and the security can be improved. In this case, the degree of adhesion can be increased by providing a rubber packing or the like.
