Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indefinite armor, stay, or the like necessary for impact protection against vibrations between parts of equipment or contact with other objects, anti-vibration protection, or thermal protection.
The present invention relates to a method for enabling fitting of a rubber material, a synthetic resin material, or the like having a cushioning or protective coating to an object having a complicated shape with respect to a protrusion or the like.

[0002]

2. Description of the Related Art In order to coat a complex-shaped object having a conventional shape with a protective coating substance, a molten cured substance is coated and then molded, or a short ring of the coated substance is immersed in water or a solvent. There has been a method of manually pushing in the above and then fitting them. However, the work is complicated and time-consuming, and the workmanship is also very poor, so improvement is required.

[0003]

Therefore, the present invention is an effective method for coating a stretchable protective substance on an irregularly shaped object as described above, by applying a pressure to the inner wall of the substance to be coated, and the whole body is covered. (EN) To provide a method of expanding or expanding the inner tube by atmospheric pressure to expand the inner tube by expanding the pressure on the outer side of the inner tube, pushing it into the mouth of an irregularly shaped object to fit it, and sequentially covering the entire body. It is an object.

[0004]

In order to achieve the above object, as a first aspect of the present invention, an elastic coil or a plurality of elastic rings are wound around a pipe made of a stretchable material,
The one end of the pipe is fitted airtightly to the small end of the amorphous object to be fitted without a gap, the fluid pressure is applied from the other end of the pipe to widen the inner diameter of the pipe, and the pipe is sequentially applied to the surface of the amorphous object. It is a method of pushing and fitting. Next, as a second claim, a pipe in which an elastic coil or a large number of elastic rings is wound on the outside of the pipe made of the elastic material according to claim 1 is inserted into a similar pipe having a larger diameter. A double pipe with both ends connected is fitted to one end of an irregularly shaped object airtightly without any gap, and the air between the double pipes is sucked from the other end of the pipe with a vacuum pump, and the diameter of the elastic inner pipe is adjusted by atmospheric pressure This is a method of sequentially pushing into the surface of an amorphous object of the spread pipe and fitting.

[0005]

The fitting method of the stretchable substance to the irregularly shaped object of the present invention configured as described above is performed by the method of the first item or the method of the second item, both of which are made of a pipe made of the elastic substance. When the internal pressure breaks the airtightness of the tip and jets out, the tip opens and is pushed forward by the momentum, and this is repeated repeatedly to fit, so it can easily pass through any curved part of an irregular shaped object and cover the target A fit can be achieved. Especially for long objects, it is advisable to divide the coated pipe into several pieces. In the method of the second item, since the elastic coil wound on the outer side of the inner pipe exists between the double pipes, the coil serves as a supporting material, so that the inner pipe can be expanded.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A method of claim 1 will be described with reference to FIG. 1. An elastic coil (2) is wound around a rubber pipe (1) and one end of this rubber pipe (1) is fitted. (F) Airtightly fit into one end of the amorphous object (3)
Then, compressed air is sent from the other end of the pipe to widen the inner diameter of the pipe by pressure, and the pipe (1) is sequentially sent to the surface of the amorphous object for fitting. After the fitting is completed, the outer elastic coil may be removed. (Fig. 2)

Next, the fitting method using a double pipe according to claim 2 will be described. In FIG. 3, a rubber pipe (1) and an elastic coil (2) are wound, and the same diameter pipe (4) having a larger diameter is used. , The end of each of the inner and outer pipes is connected to the end of the irregular shaped object (3) in an airtight manner (F), and the air between the inner and outer double pipes is vacuumed from the other end of the pipe. When sucked by the pump (P), the inner diameter of the rubber pipe (1) expands due to the atmospheric pressure, so that the double pipe is pushed into the surface of the irregular-shaped object one after another and fitted. After the fitting process is completed, the elastic coil and the large-diameter outer pipe may be removed.

[0008]

Since the present invention is constructed as described above, it has the following effects. A ball with a cushioning or protective coating for irregularly shaped armor, stays, protrusions, etc. necessary for shock protection against contact between equipment parts or contact with other things, anti-vibration protection or heat protection, etc. This is a new method that enables fitting of a material, synthetic resin material, or the like to an irregularly shaped object having a complicated shape. This is an invention that can be expected to contribute to the protection of chemicals, medicines, medicines, works of art, etc. when handling glass equipment.
