Description of the Related Art Taking an environmental test apparatus as an example, such an apparatus usually has a test chamber for accommodating a sample and exposing the sample to a predetermined temperature, humidity or temperature and humidity. The loading and unloading is performed by opening and closing the door of the test room opening. A packing for hermetic sealing when the door is closed is provided on the inner peripheral edge of the door or / and the peripheral edge of the test chamber opening.

In some cases, a sliding door is used for the purpose of saving a space for turning the doors. is there. In the case of a pivotable door by hinge connection, the packing is clamped between the door and the apparatus body by being pivotally closed,
An airtight seal is obtained. Also, in the case of a sliding door, when closing the door, place the door on the test chamber opening surface so that the packing does not interfere with the opening / closing operation of the door, making it difficult to close or open the door or damage the packing. And placed in front of the opening, and then advanced toward the opening to close the opening. Conversely, when the door is opened, the door is first retracted from the opening, and then moved parallel to the opening surface.

る複雑、高価な機構が求められる。However, a test room in an environmental test room must accurately obtain an atmosphere of a predetermined temperature, humidity, or temperature and humidity. However, even in the case of a sliding door, the airtight seal packing must be considerably strongly clamped between the door and the apparatus main body at the time of the door closing operation. A complicated and expensive mechanism that can lock the door closed against strong resistance is required.

十分とれず、結局満足のいくシールを行えない。In addition to the above problem, in the case of a sliding door, when the door slides, the packing is not damaged by the packing, and the packing does not obstruct the opening or closing operation of the door. As described above, the height of the packing must be set low, which causes a problem that accurate and reliable hermetic sealing is hindered. As a means for solving such a problem, it is sufficient to adopt a hollow tube having a circular cross section as a packing and to expand the tube by introducing a pressurized fluid such as compressed air into the tube after closing the door. Although it is conceivable to obtain a good seal, the tube with a circular cross section expands in each direction of the radial direction, so it is not possible to take a sufficient difference in height when expanding and contracting on the side to be sealed, and eventually a satisfactory seal can be performed Absent.

It is conceivable to use such a tube by fitting it into a rigid frame such as a metal frame opened on the side to be sealed. However, depending on the shape of the frame, it is difficult to fit the tube into it, The tube and the frame rub against each other due to the expansion and contraction, and the tube is damaged at an early stage.
(Approximately Kgf / cm 2 ), a large pump is required, and there is a problem that the cost is increased.

That the free stretchable folding portion formed thinner than the base wall portion for contracting an elastic restoring force to the initial state
It is.

いる。The elastic packing according to the present invention is fixedly supported on a portion where an airtight seal is required, such as an inner surface of a door or a peripheral portion of an opening which is opened and closed by the door, at a mounting portion of the base wall portion. When opening and closing the door, assists in expanding the hollow part of the packing
No fluid pressure is supplied to the tube , so the folded portion of the telescopic wall is in a contracted state, the entire telescopic wall is contracted, and the overall height of the packing is low.

の加圧流体を導入することで行われる。Therefore, the opening and closing operation of the door can be easily performed without obstruction or strong resistance by the packing, and the packing is kept under a safe condition. The hermetic seal at the time of closing the door is to arrange the door at a predetermined closing position with respect to the opening,
This is performed by introducing a pressurized fluid, such as compressed air, into the expansion assisting tube in the hollow portion of the elastic packing while being held at that position by an appropriate locking device or the like.

で、それを待って容易に開扉することができる。[0012] That is, the auxiliary expansion tube for the hollow portion of the packing.
The tube expands by introducing a pressurized fluid into the tube,
The folded portion of the elastic wall portion is stretched, whereby the entire elastic wall portion expands mainly in one direction on the opposite side to the base wall portion, so that the height of the entire packing becomes sufficient, and the periphery of the opening on the other side is increased. Or the like, or airtightly adhered to the inner surface of the door to achieve a desired airtight seal. When the door is to be opened from the closed state, the pressurized fluid may be released from the expansion assisting tube in the packing, and the release allows the expansion / contraction wall part, especially its folded part, to return to the original folded state due to elastic restoring force. It returns and the whole packing contracts and returns to a short state, so that the door can be opened easily after waiting.

定の気密シールを達成できる。Since the ridges for improving the airtightness are provided on the expansion and contraction wall, the ridges adhere well to the mating side when the packing is expanded , so that a high hermetic sealing property can be obtained. Also, there was furnished a膨伸auxiliary tube packing the hollow portion
Therefore, as described above, by introducing a pressurized fluid into the tube to expand the tube, the packing expandable wall portion expands, and the expandable wall portion is supported by the expansion tube from its inner surface and maintained. The formation is better, and the risk of being deformed by external forces and thus damaging is reduced. In addition, even if the elastic wall is slightly damaged due to abrasion caused by opening / closing operation of the door, by expanding the expansion assisting tube separate from the elastic wall, the elastic wall is pressurized and expanded. Thus, a predetermined hermetic seal can be achieved.

Since the expansion wall 2 is expanded, the expansion / contraction wall portion is supported by the expansion tube 2 from the inner surface thereof, so that the expansion and contraction becomes better, and the possibility of being deformed by external force or being damaged due to external force is reduced. Further, even if the elastic wall portion 12 is slightly damaged due to abrasion or the like, by expanding the tube 2, the elastic wall portion 12 is expanded and a desired hermetic seal can be achieved.

Without lowering the door opening / closing operability and making the door opening / closing mechanism and lock mechanism complicated and expensive, it is inexpensive and accurate.
It can be securely hermetically sealed, and can be easily attached to a predetermined site.
An elastic packing that can be manufactured at low cost can be provided. In addition, at the time of expansion and contraction,
Since the protruding ridge that is in close contact with the mating member is formed along the same direction as the cylindrical center line of the packing, when the packing expands, the protruding ridge closely adheres to the mating member, and a high hermetic seal is achieved.

Because of the expansion , the expansion and contraction wall portion of the packing is supported from the inside, so that adverse effects such as deformation or damage due to the deformation are prevented. Also, even if the elastic wall is slightly damaged due to abrasion caused by opening and closing the door, the expansion and contraction auxiliary tube, which is separate from the elastic wall, is expanded to pressurize and expand the elastic wall. Therefore, the life is long as a whole, and a hermetic seal can be achieved safely and reliably for a long period of time.
