Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a sliding door in which a mullion is attached between both doors.

[Conventional technology]

A double sliding door does not require a door pocket in the frontage opening with upper and lower frames and a vertical frame attached, but rather, for example, two doors are installed and one door is opened in one direction to open one side of the frontage. or the other door may be opened in the opposite direction to the other door to allow entry and exit from the other side of the opening.

[Problem that the invention attempts to solve]

Generally, when sliding doors are opened, one door moves to the other door side so that they are lined up side by side, so it is not possible to attach a protruding puller, so a carved puller has been used. This is because when a protruding pull is attached to a door, when one door is opened, that is, when both doors are parallel, the door and the pull of the other door will collide, and the stop will not be attached to the frame or door side. A problem arose that required measures to be taken to prevent collisions, such as installing a On the other hand, carved pulls do not interfere with the two doors, but they do not apply enough force to open and close the doors, resulting in poor operability.

In addition, when sliding doors are applied to particularly large frontage openings, there is a problem in that the middle part of the upper frame tends to bend downward, making it inconvenient to erect the door.

This idea was created in view of the above-mentioned problems, and it is a method that allows both doors to be opened and closed without any collision even if the door is equipped with a protruding puller without the need for a stopper, and also prevents the upper frame from bending. The technical challenge is to provide a sliding door with a vertical opening.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention has been developed by attaching a protruding puller 13 shorter than the width of the mullion D to the front and back surfaces of the vertical frame 3 that comes into contact with the door body B when the door is closed. When door B is opened, the protruding pull 13 is positioned in front of mullion D, so that there is a remaining pull on both door bodies based on the position of mullion D, and between both doors at the center of the frontage opening. Removable mullion D
It consists of a sliding door equipped with a mullion.

[Effect]

According to this invention, the distance between the two doors is equal to the width of the mullion located between the two doors, so the protruding pulls attached to the doors can be opened and closed without interfering with other doors. In addition, a mullion is installed between the upper frame and the lower frame, so the upper frame does not sag.
Furthermore, since the mullions are removable, by removing both doors, the frontage opening can be fully opened, making it possible to carry in and out large-volume equipment.

〔Example〕

An embodiment of this invention will be described based on the drawings. FIG. 1 is a plan sectional view of a hanger-type air-tight sliding door equipped with mullions, and FIG. 2 is a side sectional view of the same sliding door.

Hanger-type airtight sliding door A has an upper frame 1, a shoe slide 2 serving as a lower frame, and vertical frames 3, 3 assembled around the frontage opening, and doors B, B are attached to this frontage opening.
is being built. A case C is attached to the upper frame 1 side of the above-mentioned frontage opening, and approximately L-shaped rails 4, 4 are attached symmetrically to the inside, and the door bodies B ₁ , B ₁
Engage the upper hanger rollers 5, 5 and close the doors B, B.
is slidable.

As shown in FIG. 2, the case C has a substantially U-shaped cross section, with the opening side facing downward, and both opposite sides thereof being detachable using screws. This case C
In the center of the interior, there is a wall that separates the opposing sides.
Posts 6 parallel to both sides are vertically provided, and a substantially rectangular mullion D is removably attached to the middle part of the frontage opening with bolts and nuts. This mullion D is erected with its upper part located at the lower part of the support column 6 and its lower part located at the shoe slide 2.

On the other hand, the doors B, B have pulling rollers 7, 7 attached to the lower part of the door bodies _B1 , _B1 so as to fit into the rail grooves 2a, 2a of the shoe slides 2. Further, a link mechanism E is attached to the upper part of the door bodies B ₁ and B ₁ . This link mechanism E includes link members 9 and 9 that are loosely fitted between the support shafts on the side of the door bodies B ₁ and B ₁ and the support shafts on the sides of supports 8 and 8 that support the hanger rollers 5 and 5.
It is designed to absorb the amount of pulling movement of the door bodies B ₁ and B ₁ . By the way, when the frontage opening of the doors B and B is closed, the respective door bodies B ₁ and B ₁ are in the mullion D.
Rail members 2b, 2 each have an inclined surface at a portion corresponding to the rail grooves 2a, 2a of the shoe slide 2 so as to be closer to the side.
b is installed. In addition, at the top of the door bodies B ₁ and B ₁ , there are inclined guide pieces 1 that are bent and protrude in opposite directions.
0 and 10 are attached at two locations, and the inclined surfaces thereof are directed toward the doors B and B, respectively. and the door body
When B ₁ , B ₁ are on the closed side, there are pulling rollers 11 , 11 that engage with the inclined guide pieces 10 , 10 at the lower part of the rails 4 , 4 .
is attached via angle material. When the doors B and B are closed respectively, the rail members 2b and 2
b and the inclined guide pieces 10, 10 cooperate, so that the pulling rollers 7, 7 work together in the rail grooves 2a, 2a, and the pulling rollers 11, 1 work together in the inclined guide pieces 10, 10.
1 are regulated, respectively, and draw the door bodies B ₁ and B ₁ toward the mullion D side. On the other hand, on both sides in the longitudinal direction of mullion D, on both sides in the longitudinal direction of shoe slide 2, in the longitudinal direction of vertical frames 3 and 3, and in the support column 6 extending from mullion D to the respective vertical frames 3 and 3 sides.
Since the air-tight rubber 12 is attached to the lower longitudinal direction of the door, when the doors B and B are pulled toward the mullion D side as described above, the air-tight rubber 12 and the face plates of the door bodies B ₁ and B ₁ are placed in close contact to ensure airtightness.

Projecting pulls 13, 13 are attached to the front and back plates of the doors B, B, respectively. The door bodies B ₁ and B ₁ are left behind with reference to the mullion D position, and since there is a distance between the doors B and B by the width dimension of the mullion D, the protruding pulls 13 of both doors , 13 is door B,
The opening and closing operations of B do not interfere with each other's doors.

The hanger-type air-tight sliding door A configured as described above has the mullion D removably attached to the center of the frontage opening, so the middle position of the support column 6 is reinforced and supported, and the middle part of the case C is supported. In addition to preventing bending and eliminating the inconvenience of opening and closing doors B,
Since the mullion D can be removed by loosening bolts and nuts together with B, the frontage opening can be fully opened, making it possible to carry in and out large equipment.

[Effect of idea]

Since this idea is constructed as described above, there is a mullion distance between both doors, and even if a protruding pull is attached to the door, when one door is opened, the pull will collide with the other door. Things will disappear. Therefore, it becomes easier to open and close the door. In addition, since the mullion is removable, even if the middle position of the upper frame of the frontage opening tends to sag, the presence of the mullion provides reinforcement and support, eliminating sagging and eliminating inconveniences when installing the door. Since the stand can be removed, by removing the door as well, a large frontage opening can be obtained, making it possible to carry in and out large equipment.
