[Conventional technology]

In the case of a suspended movable panel equipped with a hidden door, after the movable panel is moved to a position that partitions a room or a frontage for sound insulation and light shielding, the upper edge of the movable panel and the ceiling and the lower edge and the floor are It is necessary to seal not only the gap between the movable panel and the floor surface, but also the gap between the bottom edge of the door in the movable panel and the floor. If the door remains in contact with the floor, the door cannot be opened and closed smoothly, so the seal must be raised.

In Japanese Utility Model Publication No. 56-48870 as a prior art, a downward opening is provided in the main body of a movable panel, and a door is provided in the opening, one side of which is connected to the main body of the movable panel so as to be openable and closable. At the upper and lower edges of the main body, sealing bases are arranged so as to be movable up and down, except for the door part, and inside the movable panel body, both the upper and lower sealing bases are installed by rotating from the outer surface of the main body. A link mechanism is provided to make the base protrude upward and downward, respectively, and a sealing base that seals the gap with the floor is provided on the lower edge of the door so as to be movable up and down, and a hinge of the door is provided inside the door. A swinging mechanism is provided that moves the sealing base at the lower edge of the door downward by the pushing movement of an operating rod whose tip protrudes toward the edge of the opening to be attached, and a protrusion near the lower end of the link mechanism in the movable panel body and It is proposed that the tip projection of the operating rod be associated with the tip projection of the operating rod so that the tip projection of the operating rod can be pushed in by the downward movement of the protrusion when the door is in the closed state.

[Problem that the invention attempts to solve]

In this prior art, a mechanism for tensioning the sealing bases at both upper and lower edges of a movable panel with a hidden door upward and downward away from the movable panel body, and a mechanism for lowering the sealing base at the lower edge of the door, which is a hidden door, are provided.
Since it is related to a link mechanism in the movable panel, a large force is required to move the link mechanism from the outside of the movable panel, and it cannot be operated smoothly with a light force.

In addition, in order to fix a movable panel at a stopped position, in addition to pressing the movable panel against the end face of an adjacent movable panel or the end face of the frontage, it is also necessary to move the sealing base up and down. There was also the problem that it was time consuming.

The purpose of the present invention is to solve the conventional problems by making it possible to seal the gap between the lower end of the submerged door and the floor simply by pressing the movable panel to the stop position.

[Means for solving problems]

Therefore, the present invention provides a frame with a downward opening in the main body of the suspended movable panel, and one side edge of the door frame of the hidden door is pivoted to the frame via a hinge so that it can be opened and closed. In the panel, a sealing base that closes the gap with the floor surface is movably disposed on the lower edge of the door frame in the subdoor, and the sealing base is drawn into the door frame and biased. A rod with a biased tip protruding toward the frame on which the hinge is attached is provided in a substantially horizontal manner, and the rod and the sealed base are connected via a link mechanism, and the tip of the rod is pushed in to close the sealed base. The movable panel is configured such that the movable panel is configured to descend toward the floor surface, and a hinge in the frame is attached to an operating rod, one end of which is biased so as to protrude toward the end surface of the movable panel in the moving direction. One end of the operating rod is arranged so as to be movable forward and backward between the side end surface on the opposite side, and when the end surface in the moving direction of the moving panel having the submerged door comes into contact with the end surface of the adjacent moving panel or frontage member. is configured so that the other end abutting portion of the operating rod faces the position where the tip of the rod is pressed.

[Functions and effects of the idea]

According to the present invention, the main body in the movable panel;
This means that an operating rod is provided between the frame to which one side edge of the door frame of the subdoor is attached so that it can move forward and backward parallel to the moving direction of the moving panel, and the operating rod has one end attached to the frame. Since the movable panel is biased to protrude from the end face in the direction of movement, when the movable panel with the submerged door is moved, the sealing base at the bottom edge of the submerged door is away from the floor surface, so it does not slide. , the movable panel can be moved with light force.

At the position where the movable panel stops, the end face of the frontage member or the end face of the adjacent movable panel comes into contact with the end face of the movable panel with the submerged door, and at the same time one end of the operating rod is pressed. The other end abutting portion presses the tip of the rod protruding from the door frame of the closed door against the frame of the opening of the movable panel.

As a result, the sealing base, which is movable up and down at the lower edge of the door frame of the hidden door that is closed to the movable panel, moves downward due to the movement of the rod and the link mechanism connected thereto, and touches the floor surface. It is possible to seal the gap between. In other words, simply by pressing the movable panel with the submerged door to the stop position, the seal can be easily sealed without requiring any other operation.

Furthermore, when the closed door is opened centering on the hinge, the tip of the rod provided in the door frame of the door moves away from the abutting part of the protruding operating rod as the door rotates. , the sealing base automatically separates from the floor surface, allowing the door to be opened with a light force; conversely, when the door is closed parallel to the movable panel, the tip of the rod is pressed by the abutting part of the operating rod. This allows the airtight base to seal the floor and the gap.

As described above, according to the present invention, not only can the sealing base at the lower edge of the subdoor be moved up and down in accordance with the opening/closing operation of the subdoor, but also the movement can be performed without involving the vertical movement of the sealing base at the upper and lower ends of the movable panel. This has the remarkable effect of being able to press the sealing base at the lower edge of the closed subdoor onto the floor by simply pressing the panel against the end face of the adjacent movable panel or the end face of the frontage member.

〔Example〕

Next, an embodiment of the present invention will be described. In the figure, reference numeral 1 denotes a movable partition panel equipped with a submerged door 2, 3 a box-shaped guide rail disposed on the floor, and 4 a box-shaped guide rail disposed on the ceiling. An open passage is formed in the lower surface of the rail 4 along its longitudinal direction.

Reference numerals 5 and 5 refer to a suspension rod that projects upward from an appropriate location on the upper end of the movable panel 1 and faces into the open passage in the guide rail 4. The movable panel 1 is moved along the inner guide surface of the guide rail 4 by rotating rollers provided at the upper end thereof. Configure it to do so.

A frame 7 with a downward opening is fixed to the main body 1a of the movable panel 1, which is pivotally connected to one side edge of the door frame 2a of the submerged door 2 via a hinge 6.

Therefore, the main body 1a of the suspended movable panel 1
is formed in a downward U-shape when viewed from the front, and the main body 1a
A compression rod 1 is provided with upwardly drawn and biased sealing bases 10, 10 disposed on the lower edges of both the left and right sides of the
1 and 11, and a compression rod 13 is connected to a downwardly drawn and biased sealing base 12 disposed on the upper edge of the main body 1a.
1 and 13 are connected via a link mechanism 14, and can be operated up and down using an operating lever 15 on one side of the main body 1a.

A seal piece 16 made of rubber or the like is attached to each of the sealing bases 10, 10, 12, which comes into contact with the floor surface 3 or the lower surface of the guide rail 4 when the base body protrudes.

A sealing base 18 with a seal piece 16 having the same cross-sectional shape as each of the sealing bases is provided in the lower frame 17 of the lower edge of the door frame 2a of the subdoor 2, which has a downward U-shaped cross section.
are arranged so that they can move up and down.

The link mechanism 19 for vertically moving the sealing base 18 includes a vertically movable pipe member 22 disposed between a bracket 20 on the upper surface of the longitudinally intermediate portion of the lower frame 17 and a unit frame 21 located above the bracket 20. ,
It consists of a bell crank lever 24 which is pivotally attached to the upper end of the pipe member 22 and whose midway portion is pivotally attached to the unit frame 21 by a pin 23.The other end of the bell crank lever 24 has a base end of a horizontal rod 25. The tip of the rod 25 is slidably protruded from a hole on one side of the door frame 2a where the hinge 6 is attached, and the rod 25 is attached to the frame 7 by a tension spring 26.
The pipe member 22 is urged upward by a tension spring 27, while a bar 28 projecting upward from the sealing base 18 can be slid vertically on the pipe member 22. Insert it into the

9 to prevent it from falling, and furthermore, the collar piece 30 on the outer periphery of the pipe member 22 and the sealing base 1
8. A compression spring 31 is fitted between the top surface and the upper surface.

Therefore, when the tip of the rod 25 is not pressed, the biasing force of the tension springs 26 and 27 is stronger than the force of the compression spring 31, and the sealing base 18
When the rod 25 is pressed, the sealing base 18 moves downward, and the sealing piece 16 of the sealing base 18 is pressed against the floor surface 3 by the biasing force of the compression spring 31 to close the sealing base 18. I can do it.

In the main body 1a of the movable panel 1, there is an operating rod 3.
2 is horizontally arranged between the side end surface of the frame 7 on which the hinge 6 is attached and the end surface of the movable panel 1 in the moving direction, and the left and right middle portions of the operating rod 32 are connected to bearings 33, 34. It is supported so that it can move forward and backward through. The pressing piece 35, which is one end of the operating rod 32, is urged by a spring 38 so that the end surface in the moving direction of the movable panel 1 with a submerged door protrudes toward the adjacent movable panel 37 or the end surface of the frontage member. An abutment part 36 formed in an L-shape at the other end of the rod 32 faces the side of the subdoor 2 facing the tip end of the rod 25.

When the movable panel 1 with the submerged door 2 comes into contact with the adjacent movable panel 37 or the end face of the frontage member and stops, the pressing piece 35 of the operating rod 32 is pressed against the end face of the movable panel 37, etc., and the operating rod 32 is pushed in so that the other end abutting portion 36 of the operating rod 32 comes to a position where it presses the tip of the rod 25.

In this configuration, when the sliding door 2 is held in a closed state with respect to the frame 7 of the movable panel 1 which is suspended from the guide rail 4 and is movable, the tip of the rod 25 in the sliding door 2 comes into contact with the operating rod 32. 36, but is not pressed against the contact portion 36, so that the sealing base 18 in the hidden door 2
are urged to be pulled in by tension springs 26 and 27, and are separated from the floor surface 3.

Therefore, when the movable panel 1 is moved along the guide rail 4, the seal piece 16 of the sealing base 18 is not supported by the floor surface 3, and the movable panel 1 can be moved with a light force.

Move the movable panel 1 and press it against the end face of the frontage member or against the end face of the adjacent movable panel 37 (if the rod 25 of the movable panel 1 with a submerged door protrudes backward in the direction of movement, When the movable panel 37 is pressed from the rear side), one end of the operating rod 32 on the movable panel 1 is pressed and moved (see the two-dot chain line in FIG. 3), and its abutting portion 36 touches the tip of the rod 25. By pushing and lowering the pipe member 22 via the link mechanism 19 and lowering the sealing base 18, the gap with the floor surface 3 can be sealed.

When the door 2 is opened around the six hinges as shown by the two-dot chain line in FIG. This protrudes and the sealing base 18 is pulled up, allowing the door 2 to be opened and closed easily without scraping the floor 3.

With this simple structure, the present invention allows the sealing base at the lower edge of the submersible door to be moved downward and to be released without being sealed.
