Description

[Detailed description of the invention] [Field of industrial application] This invention is suitable for parts such as bolts and nuts used in high-altitude work such as waveguide piping work on the vertical ladder of a wireless tower or work on antenna poles. This invention relates to a receiver that prevents objects from falling.

[Prior art]

For example, in piping work for waveguides on a vertical ladder of a radio tower, a receiver 1 shown in FIG. 11 is used to prevent members such as bolts and nuts from falling. This receiver 1 has a net 3 stretched over a U-shaped frame 2 in the form of a saucer, and a pair of hanging rods 4, 4 are attached to the frame 2 in an upright manner. A connecting rod 5 having a hook piece between its tip portions is installed.

FIG. 12 is a diagram showing how to use this receiver 1. The receiver 1 is hung and held by hooking the hooking piece of the connecting rod 5 onto the foothold bar 7a of the ladder 7 so that the net 3 is positioned below the operator's hand. Therefore, even if bolts, nuts, etc. are accidentally dropped from the worker's hand, they are caught by the net 3 of the receiver 1 and prevented from falling downward.

However, when the waveguide 8 is already attached to the ladder 7, the connecting rod 5 is obstructed by the existing waveguide 8, and the attachment of the support 1 to the desired position is restricted, or There were times when I couldn't do it at all.

Furthermore, as is clear from Fig. 12b, the net 3 of the support 1 protrudes toward the worker, and the ends hit the worker's waist, knees, etc., making the worker feel unnatural and unstable. I was forced to work in an awkward position,
This reduced work efficiency and was also dangerous.

In order to avoid this, if the installation position of the net 3 is lowered below the feet, the distance from the worker's hand to the net 3 will increase, which may reduce the effectiveness of catching falling parts and increase the danger. Ta.

Furthermore, even if there is no existing waveguide 8, it is possible to install a ladder 7 in the newly installed waveguide 8' as shown in FIG. 12c.
The edge of the net 3 on the side hits, and that part is pushed in and deformed into a V shape, making it impossible to cover the entire periphery of the waveguide 8' with the net 3, reducing the effect of catching falling members. There was a problem.

[Purpose of invention]

The purpose of this invention is to enable easy installation in the desired position regardless of the presence or absence of existing waveguides on the ladder of a steel tower, etc., and to enable workers to work in a stable posture. To provide a member fall prevention bracket for working at high places, which is not deformed by waveguides, etc., and can be used in a wide variety of applications.

[Structure of the idea]

For this reason, the receiver of the present invention has a fitting hole with a shape corresponding to the outer shape of the pole-shaped body, and a supporter that can be attached to and detached from the pole-shaped body, and a supporter that can be attached to and detached from the outside of the supporter and that can be attached to the supporter. and a bottomed receiving bag attached to the mounting band and having a removable opening/closing part at one end. By attaching the supporter to the pole-shaped body and closing the opening/closing portion, the receiving bag can be attached to surround the pole-shaped body.

An attachment/detachment tool 15 made of fastener tape (for example, magic tape) that can be reattached and detached from the outer peripheral surface is attached.

Reference numeral 16 denotes a mounting band that is attached to the outside of the supporter 11, and as shown in FIG. 6, there is a detachable tool 15' on the inner surface that forms a pair with the detachable tool 15, and fasteners on both ends for attaching and detaching between them. 17 and 17' are attached respectively. A hinge 18 is provided on the opposite side of the fasteners 17, 17'.
A plurality of frame attachment portions 19 are attached to the outer peripheral surface at appropriate intervals.

20 is a bent frame made of piano wire,
Each frame 20 has one side (lower side) pivotally attached to the frame mounting portion 19 and the other side bent upward to form an upright shape.

Reference numeral 21 denotes a receiving bag formed by stretching a sheet such as a vinyl sheet, cloth, or net over each of the frames 20 and the attachment band 14. This receiving bag 21
The upper surface is open, and the bottom corner (inner peripheral portion) is formed lower than the central portion (see Figure 3),
Further, an opening/closing portion 22 is formed at a position that matches the mounting position of the fasteners 17, 17' of the mounting band 16,
Attachment and detachment tools 23 and 2 similar to the aforementioned attachment and detachment tools 15 and 15' for attaching and detaching the opening and closing portion 22 to both edges thereof.
3' is attached.

Now, in order to assemble this receiver 1, first,
As shown in Figures a and b, the supporter 11 is fitted inside the mounting band 16, and the attachment/detachment tools 15, 15' are adhered to fix the two. At this time, supporter 11
cutout 13 and fasteners 17, 1 of the mounting band 16
Match the positions with 7'.

Next, the frame 20 and the receiving bag 21 are unfolded, and the attachment/detachment tools 23, 23' of the opening/closing part 22 are adhered, so that the receiving bag 21 is formed into a container shape.

To attach this to the waveguide 8, as shown in Fig. 7c,
As shown in d, the opening/closing part 22 of the receiving bag 21 and the fasteners 17, 17' of the mounting band 16 are bonded and engaged,
The part is pushed in to fit the waveguide 8, and the fitting hole 12 of the supporter 11 is held onto the waveguide 8.

Next, the fasteners 17 and 17' are locked, the supporter 11 is tightened, and the waveguide 8 of the supporter 11 is tightened.
Securely fix the mounting condition. Finally, the receiving bag 21 is attached so as to surround the waveguide 8 by gluing the attachment/detachment tools 23 and 23'.

FIG. 8 shows an example of the use of this support 10 on a vertical ladder. The receiver 10 is attached to the newly installed waveguide 8'. In this case, the receiver 10 can be installed at any position near the working hand of the waveguide 8'. In addition, bolts, nuts, etc. that have fallen into the receiving bag 21 are collected at the corners of the bottom of the receiving bag 21, making it easy to check and pick them up.

In this embodiment, the supporter 11 is attached to the mounting band 16.
It is separated and independent from the. For this reason, if a plurality of supports 11 with different shapes of fitting holes 12 are prepared, they can be used to replace not only circular but also elliptical, rectangular waveguides, etc. Alternatively, it can also be attached to a coaxial feeder line, antenna pole, etc.

FIG. 9 shows an example in which the present receiver 10 is attached to a TV antenna pole 24 installed on the roof of a building, etc., and the receiver 10 is used during work such as installing or replacing a booster amplifier 25 of a TV antenna. catch falling objects such as parts and screws.
