Abstract

PROBLEM TO BE SOLVED: To enable the installation of a pipe in a desirable position of an installation member with one hand in a narrow space by enabling temporary stopping to bent portions of fixed arms and pressing arms abutted against an outer periphery of the input shaft member, and narrowing a space between the bent portions. SOLUTION: A circular arc virtually formed by bent portions 5a, 7a of fixed arms 5, 7 and a bent portion 13a of a pressing arm 13 has a diameter a little larger than an outer diameter of an installation shaft member 9. Engagement grooves 5d, 7d, 13d are formed on inner peripheral surfaces of the bent portions 5a, 7a of the fixed arms 5, 7 and the bent portions 13 of the pressing arm 13, so as to engage with spiral grooves or deformed portions formed on an outer periphery of the input shaft member 9. A locking plate 11 has width such that the circular arc formed by the bent portions 5a, 7a, 13a has a diameter smaller than the outer diameter of the input shaft member 9 when the locking plate 11 is locked to a portion 13b.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to various cables (electricity, control signals), liquid (air, oil, water, etc.) pipes (the pipes include a supply pipe and a discharge pipe. And a pipe) for suspending and fixing a pipe.

[0002]

A suspension fixture for suspending and fixing a pipe on a mounting shaft member such as a threaded bolt or a modified bolt whose end is planted on a wall surface or a ceiling is, for example, a main body portion. An upper grip portion and a lower grip portion, which are engaged with each other on the outer circumference half of the mounting shaft member, are provided on the upper and lower portions at a distance of at least the diameter of the mounting shaft member and at least on the side surface of the main body. It is generally known that a band portion that fits over a half circumference of a pipe is provided.

In the above-mentioned conventional hanging fixture, the main body is erected with the mounting shaft member positioned between the upper and lower grip portions which are first laid down horizontally, with a predetermined interval in the vertical direction. After engaging the upper and lower grip parts over each half of the outer circumference of the opposing mounting shaft member, the band is elastically deformed, and the pipe is press-fitted and clamped in the space part to obtain the desired height of the mounting shaft member. The pipe is suspended and fixed at the position.

However, in the above-mentioned conventional hanging fixture, when the mounting position of the pipe with respect to the mounting shaft member is to be changed after the pipe is mounted, the position of the pipe is kept when the pipe is mounted. I couldn't change it. Therefore, while removing the attached pipe and holding it with one hand, lay down the main body part with the other hand and change the meshing position of the upper and lower grip parts with the mounting shaft member to adjust the height. It had to be done and the workability was poor. Particularly, in a narrow space such as a ceiling or a wall, it is difficult to insert both hands, so that the above work cannot be performed efficiently.

Further, since it is not possible to adjust the mounting position of the pipe with respect to the mounting shaft member in a state where the pipe is attached to the hanging fixture, it is necessary to mount the pipe with a slight inclination such as a drain drain pipe. Had to remove the pipe after every position adjustment, and it took a lot of time and labor to adjust the mounting position.

The present invention has been invented to solve the conventional drawbacks, and its object is to be able to mount a pipe at a desired position of a mounting shaft member with one hand even in a narrow space. Thus, it is possible to provide a hanging fixture for a pipe that can efficiently perform the work of attaching the pipe.

Another object of the present invention is to provide a suspending fixture for a pipe, the position of which can be easily adjusted with the pipe being attached.

[0008]

Therefore, according to the present invention, a fixed arm portion having a curved portion, which is substantially coincident with a part of an outer peripheral surface of a mounting shaft member to be mounted, is provided in a main body portion provided with a pipe holding portion. And a pressing arm portion having a curved portion which substantially matches and is opposed to the curved portion of the fixed arm portion. A lock member is provided at the end of the fixed arm or the pressing arm so that the free end can be locked at the end of the other arm so as to be bendable.

Then, when the mounting shaft member is inserted between the curved portions of the fixed arm portion and the pressing arm portion, the hanging fixing tool is brought into contact with the outer peripheral surface of the mounting shaft member by the curved portions of the fixed arm portion and the pressing arm portion. To temporarily stop. Further, in the above state, the free end portion of the locking member is locked to the end portion of the other arm portion so that the interval between the curved portions is narrowed and the hanging fixture is held by the mounting shaft member.
