Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an airtight device for a sliding door, and more particularly to an airtight device for facilitating separation of an airtight member using a magnet by the sliding door.

[0002]

[Prior art]

 As shown in, for example, Japanese Utility Model Publication No. 63-1754, an airtight state of an airtight device in a conventional sliding door is easily released. In addition, an airtight material with a magnet is attached to the vertical frame of the sliding door so that it can be retracted, and when the sliding door is closed, the magnets stick to each other to form an airtight state. It has been known that the provided cam is inserted between magnets that are attracted by moving a sliding door to separate the airtight material to reduce the separating force.

[0003]

[Problems to be solved by the device]

 The airtight device that uses the cam to separate the airtight material requires a strong force at first because the tip of the inclined surface of the cam is inserted into the attraction surface of the magnet by the movement of the sliding door to separate it. However, there is a need for a material that can peel off the airtight material with a small force without difficulty. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve the above problems and to provide an airtight device for a sliding door in which the airtight material can be easily peeled off with a small force.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a sliding door airtight device in which airtight members 7 and 7a using magnets are attached to vertical frames 3 and 5 which overlap each other when the shoji 4 is closed to form an airtight state. The one vertical frame 3 is provided with an airtight member storage section 12 with one side opening wide, and the magnet 6 attached to the other vertical frame 5 and the magnet 11 attracted to the other end of the airtight member storage section 12 are provided. The built-in airtight portion 8 and the airtight member 7, 7a in which the attachment portions 9 and 9a attached to the bottom of the airtight member storage portion 12 are connected by the elastically deformable connection portions 10 and 10a are stored to open the shoji. The airtight portion is tilted so that the attraction surface of the magnet is separated from the end portion.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view of an airtight device of the present invention, and FIG. 2 shows an example in which the airtight device is attached to a sliding door. The airtightness device of the present invention is attached to the overlapping parts of sliding doors, sliding doors, etc. to form an airtight state, and the one shown in FIG. The magnets 6 and 11 are attached to the facing surface of the overlapping portion of the vertical frame 3 of the fixed portion 2 and the vertical frame 5 of the shoji 4 to attract the magnets 6 and 11. The shoji screen 4 moves and opens and closes as shown by the arrow in FIG. 2. When the shoji screen 4 is closed, the magnet 6 is built-in and fixed vertically in the vertical frame 5 that overlaps with the vertical frame 3 of the fixing part 2. Has been done. An airtight member 7 is attached to the end of the vertical frame 3 of the fitting / fixing portion 2 in the vertical direction so as to adsorb the magnet 6 built in and fixed to the vertical frame 5 of the shoji 4 to form an airtight state. . As shown in FIG. 1, the airtight member 7 is composed of an airtight portion 8, a mounting portion 9 and a connecting portion 10 that connects the both, and the airtight portion 8 has a magnet 6 of the shoji 4 and a magnet 11 attracted when closed up and down. The mounting portion 9 is built in and fixed in the direction, and the rear end is provided with a mounting portion 9 which is fitted and mounted in a mounting groove 16 at the bottom of the airtight member housing portion 12 provided in the vertical direction of the vertical frame 3. The airtight portion 8 and the mounting portion 9 are connected by a flat connecting portion 10 which is elastically deformable in the left-right direction. The airtight member housing portion 12 for housing the airtight member 7 is formed in a groove shape in the vertical direction of the vertical frame 3 of the fitting and fixing portion 2, and the inner wall of the airtight member housing portion 12 moves to open the shoji 4. The wall is a slanted wall 13 formed to have a wide mouth, and when the magnet 4 is peeled off when the shoji 4 is opened, the airtight portion 8 is tilted as shown in FIG. 3 so that the magnet can be peeled from the end portion. It is configured to form the tilting space 14. The inner wall on the opposite side is a vertical wall 15 which is configured so that the airtight portion 8 is fixed so as not to move when the shoji 4 is closed, and is faced to the magnet 6 of the shoji 4 to be securely attracted. . Further, a mounting groove 16 for fitting and mounting the mounting portion 9 of the airtight member 7 is provided at the bottom of the airtight member housing portion 12. The mounting groove 16 is configured to movably fit the mounting portion 9 of the airtight member 7 to the shoji side by a partition plate 17, and the magnet 11 of the airtight portion 8 is attracted when the shoji 4 is opened. As shown in FIG. 3, the airtight member 7 is slightly retracted to facilitate the tilting of the airtight portion 8 when it is moved together with the magnet 6 of the shoji 4 in the opening direction and tilts to peel off. As shown in Fig. 1, the magnet attracts to move forward to form an airtight state. It is possible to separate the magnet 11 by tilting the airtight portion 8 by moving the shoji 4 without fixing the attachment portion 9 and moving it.

FIG. 4 and FIG. 5 show another embodiment, which is a cylindrical shape having an elastically deformable hollow portion 18 in place of the elastically deformable flat connecting portion for the airtight member connecting portion. The connecting portion 10a is attached so that the attaching portion 9a is fixed, and when the shoji 4 is opened, the connecting portion 10a can be easily deformed by moving the shoji 4 to tilt the airtight portion 8 for peeling. It is the one. In the above-mentioned embodiment, the airtight member storage portion is provided in the vertical frame of the fitting and fixing portion so that the airtight member can be stored and attached.However, the airtight member storage portion is provided on the shoji side to store and install the airtight member. Also, in order to form an airtight state on the door stop side of the shoji screen, a protruding piece that overlaps with the vertical frame on the door stop side of the shoji screen is projected on the vertical frame of the window frame, and the airtight member is attached to the protruding piece. It can also be applied to an airtight device in which is attached.

[0007]

[Effect of device]

 The present invention is constructed as described above, and one of the vertical frames that overlap with each other is provided with the airtight member storage part with one side wide open, and the tiltable airtight member is stored in the airtight member storage part. Since the airtight part is tilted to separate the magnets by the moving force when opening the shoji, the magnets are gradually separated from the end of the magnet as the shoji moves, so the airtight device can be easily released with a small force. It has a very good effect that
