Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a moving partition seal mechanism that can achieve good sealing performance.
[0002]
[Prior art]
In a moving partition that freely partitions the room, a movable member with a sealing material that is driven toward the outside of the moving panel is incorporated into the moving panel in order to improve the sealing performance of the moving panel, such as sound insulation, airtightness, and heat insulation. (For example, JP-A-3-72188).
[0003]
The movable member is housed so as to be relatively movable toward the outside of the movable panel with respect to an outward guide groove formed on the peripheral end surface of the movable panel, and is movable through a manual or electric drive mechanism called a power closer. By driving in the direction, a sealing material can be brought into close contact with a ceiling surface, a floor surface, left and right wall surfaces and the like (hereinafter, simply referred to as a ceiling surface or the like) to complete the sealing of the movable panel. In order to further improve the sealing performance, it is also known to attach another soft sealing material for filling the air and swelling the movable member (JP-A-2002-89148).
[0004]
[Problems to be solved by the invention]
According to this conventional technique, since the movable member is housed in the outwardly facing guide groove on the peripheral end surface of the movable panel so as to be relatively movable, it is indispensable to provide a gap between the movable member and the wall surface of the guide groove. However, since the air inside and outside the room flows through this gap, there is a problem that the sealing performance is not always sufficient.
[0005]
Accordingly, an object of the present invention is to provide a moving partition seal mechanism capable of easily realizing better sealing performance by appropriately combining the first and third movable members in view of the problems of the related art. To provide.
[0006]
[Means for Solving the Problems]
According to a configuration of the present invention for achieving the above object, the first movable member housed in the outward guide groove on the peripheral end surface of the movable panel is connected to the inner side of the first movable member via a sealing material. A third movable member; and a drive rod for driving the first and third movable members. By driving the drive rod toward the outside of the movable panel, the first movable member is provided on the movable panel. The gist is that the third movable member projects outward when the first movable member stops, and the third movable member moves outward, and the sealing material elastically deforms and comes into close contact with the wall surface of the guide groove.
[0007]
The second movable member is housed in the first movable member that opens outward, and by driving the drive rod, the second movable member projects out of the movable panel together with the first movable member. When the first movable member stops, only the second movable member may further project, and when the second movable member stops, the third movable member may move outward.
[0008]
Further, the second movable member is connected to an extension rod that is connected to the drive rod so as to be extendable and contractible, and the first movable member is connected between the drive rod and the extension rod and between the extension rod and the first movable member. The third movable member can be driven by a drive rod via a spacer which acts when the compression spring is compressed, through a strong and weak compression spring interposed therebetween.
[0009]
Further, the guide groove may be formed by a fixed guide member provided on the peripheral end surface of the movable panel, and the first and second movable members may be provided with outward sealing materials, respectively.
[0010]
The corner member is held by the first movable members on two adjacent sides of the movable panel, and the corner member is connected to the first right-angle member and the inside of the first right-angle member via a sealant. The second right angle member can be connected to the second movable members on two adjacent sides of the movable panel, and the first right angle member is provided with an outward sealing material. Can be attached.
[0011]
[Action]
According to the structure of the invention, the first movable member is housed so as to be relatively movable toward the outside of the movable panel with respect to the outward guide groove formed on the peripheral end surface of the movable panel. The movable member is connected to the inner side of the first movable member via a sealing material. Therefore, when the first movable member is protruded to the outside of the movable panel via the drive rod and the first movable member is stopped against the ceiling surface or the like, the third movable member moves outward, The seal member is elastically deformed in the lateral direction and comes into close contact with the wall surface of the guide groove. That is, the first movable member seals a gap between the movable panel and a ceiling surface around the movable panel, and the sealing material connecting the first and third movable members is formed of the first movable member and the guide groove. The gap between the wall and the wall can be effectively sealed. Note that the third movable member moves outward toward the outside of the movable panel in conjunction with the first movable member until the first movable member stops, and when the first movable member stops, It moves further outward so as to approach the first movable member.
[0012]
The second movable member housed in the first movable member moves outward together with the first movable member and protrudes outside the movable panel until the first movable member stops, and the first movable member moves out of the movable panel. When stopped, only the second movable member moves further outward and protrudes to the outside of the movable panel, and when the second movable member stops, the third movable member moves outward to complete the seal by the sealing material. . That is, the first and second movable members eventually protrude stepwise outside the movable panel, and can more effectively seal the gap around the movable panel. However, a shallow groove corresponding to the second movable member is formed on the ceiling surface around the movable panel.
[0013]
The first, second, and third movable members are connected to or driven by the driving rods via the compression springs, the extension rods, and the spacers, respectively, to drive the driving rods outward only. Thus, it is possible to sequentially move outward. Until the first movable member stops, the first and second movable members move in conjunction with each other by maintaining both free lengths of the compression springs. When the first movable member stops, the weaker compression is performed. When the spring contracts, only the second movable member moves via the extension rod, and when the second movable member stops, the stronger compression spring contracts, causing the third movable member to move via the spacer. Because it moves.
[0014]
The guide groove formed by the fixed guide member can easily and sufficiently finish the inner wall surface to which the seal member connecting the first and third movable members is in close contact. In addition, the guide member may use a channel-shaped aluminum extruded profile that opens outward, and a pair of left and right aluminum extruded profiles that face each other and form an outward guide groove in the middle. Is also good.
[0015]
The outward sealing material attached to the first and second movable members is appropriately elastically deformed and brought into close contact with the ceiling surface by stopping the first and second movable members against the ceiling surface or the like. Then, the gap between the moving panel and the ceiling surface is effectively sealed. It is preferable that the sealing material attached to the first and second movable members be sufficiently harder than the sealing material connecting the first and third movable members, respectively.
[0016]
The corner member that combines the first and second right-angled members can effectively seal the gap generated at the corner of the movable panel via the sealant that connects the first and second right-angled members. The inner second right angle member is connected to the second movable members on two adjacent sides of the movable panel, and only the second movable member relatively moves with respect to the first movable member. This is because the sealing material can be elastically deformed in the lateral direction and can be brought into close contact with the inner wall surface of the first movable member. The first movable members on two sides adjacent to each other are cut at an angle of 45 ° at the respective ends, and finished so that they can be joined at right angles to each other at the corners of the movable panel. Further, the sealing material connecting the first and second right-angle members can be made of the same quality and the same shape as the sealing material connecting the first and third movable members.
[0017]
The outward sealing material attached to the first right-angled member adheres to two right-angled surfaces such as a ceiling surface and a wall surface, and a wall surface and a floor surface, and forms a gap between the moving panel and the moving panel at a corner of the moving panel. Can be sealed. In addition, the sealing material attached to the first right-angled member can be made of the same quality and the same shape as the sealing material attached to the first and second movable members.
