DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe or a fluid (water, oil, air, refrigerant of an air conditioner, etc.) in which cables (electricity, signal lines) are accommodated in bolts previously implanted on a wall or a beam. The present invention relates to a pipe suspender for fixing a pipe through which the above-mentioned method is carried.

[0002]

SUMMARY OF THE INVENTION The applicant of the present invention has disclosed, for example, in Japanese Patent Application No. 8-355083, a structure in which a main body is provided with a shaft adjacent to a fixed support member for supporting the outer peripheral surface of the shaft member at upper and lower portions thereof. A pressing support member for supporting the outer peripheral surface of the member is provided, and a tube holding member for holding the outer peripheral surface of the tube at least over a half circumference is provided on the main body opposite to the fixed supporting member and the pressing supporting member, and the fixed supporting member is pressed. In a pipe hanger provided with an urging member for elastically deforming the supporting member to pinch the shaft member, the fixing member extends in a horizontal direction orthogonal to the axis of the shaft member with respect to the upper fixed supporting member or the urging member. A tube pressing member having an engagement portion engaging with one or both of the support member and the body portion and a tube contact portion contacting the upper outer peripheral surface of the held tube is provided in a bendable manner. Retained tube The tube pressing member on the outer peripheral surface upper proposed contactable to the tube hanger.

[0003] In this pipe hanging device, the mounting position can be easily finely adjusted with respect to a shaft member such as a bolt planted on a wall surface or a beam. However, the main body and the pipe holding member are integrally formed of synthetic resin such as polypropylene. Because of the molded structure, it is suitable for hanging relatively light pipes such as drain pipes, but for heavy metal pipes such as refrigerant pipes of air conditioners, for example, The tube holding portion was easily cut off due to deterioration of the synthetic resin due to use over time, and the tube could not be stably held for a long period of time.

Further, since the thickness of the tube holding portion is set in advance, in order to suspend tubes having different tube diameters, it is necessary to prepare tube suspending tools corresponding to various tube diameters.

[0005] These drawbacks include, for example, a band having a large number of locking portions oriented in a plane perpendicular to the longitudinal direction, an opening into which the band is inserted at one end of the band, and elastic deformation in the opening. This can be solved by using a known binding band integrally formed with a locking portion provided with a locking claw that engages with the locking groove. It was extremely difficult to release the locked state later, and there was no other way to remove the tube except to cut the band. For this reason, in order to hold the tube again, a new binding band must be used, and there is a problem that the cost of mounting the tube increases.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned conventional drawbacks, and an object of the present invention is to make it possible to easily suspend various pipes having different pipe diameters and to install the pipes even after installation. It is an object of the present invention to provide a pipe hanging tool that can easily release a pipe holding state.
