Description

[Detailed Description of the Invention] This invention relates to a hanging device, such as an evacuation ramp, which allows the speed of movement of a lifesaving rope to be controlled.

When setting evacuation equipment such as the above-mentioned descending device on the top of a high-rise building, a hanging device is generally used.

However, in the case of conventional hanging equipment, it is a structure that is assembled using steel materials such as angles and channels, and fixed at a specific location such as on the rooftop. It is very inconvenient to have to travel to

Furthermore, since the structure is such that the evacuation equipment is fixed at a specific position, it may sometimes not be possible to move it to that position, and there is a risk that the evacuation equipment may become unused.

Therefore, the purpose of this invention is to provide a hanging device that can be easily set on the side of an upright wall, such as on both sides of an indoor window, and can be firmly attached. There is.

This idea involves attaching a pressure pad to a pad support frame that is movable relative to the positioning pad, and providing a spring that presses the pad support frame toward the pressure pad.
A pressure pad is attached to the pad support frame, and a pair of plates that guide the movement of the pad support frame swingably support the hanging arm, and the positioning pad is placed between the positioning pad and the pressure pad on the side of the wall. The pad support frame is positioned and the wall is clamped by the elasticity of the spring applied to the pad support frame, and then the hanging arm is swung horizontally, and the swinging movement of the hanging arm moves the pad support frame toward the positioning pad. Then, a part of the wall is held between the two pads.

An embodiment of this invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 3, a support arm 1 made of a square pipe is provided with a support piece 2 horizontally at the end thereof.
A pad support 3 is attached to the support arm 1.

The pad support 3 has a pad support plate 5 provided on the outside of a slidable cylinder 4 fitted on the outside of the support arm 1, and an elastic positioning pad 6 is attached to the pad support plate 5. .

A nut 7 is fixed to the outside of the cylindrical body 4 of the pad support 3, and the end of a threaded rod 8 screwed into the nut 7 can be rotated by a protrusion 9 provided at the end of the support arm 1. , and is supported immovably in the axial direction, so that when the threaded rod 8 is rotated, the pad support 3 moves along the support arm 1.

Further, tightening nuts 10 are screwed into the threaded rod 8 on both sides sandwiching the nut 7, and when these tightening nuts 10 are rotated and brought into contact with the end surface of the nut 7, the screw rod 8 is rotated. The movement of the pad support 3 can be prevented.

Said support piece 2 extending laterally from the end of the support arm 1
A pair of plates 11, 11 are provided facing each other, and a pad support frame 12 is disposed between the plates 11, 11.

The pad support frame includes a rectangular guide hole 13, and the support piece 2 is inserted into the guide hole 13 so as to be movably supported relative to the positioning pad 6, and elastic pressure is applied to the positioning pad 6. A pad 14 is attached.

Further, a guide shaft 15 that passes through the support piece 2 is attached to the pad support frame 12, and a spring 16 fitted on the outside of this guide shaft 15 presses the pad support frame 12 toward the positioning pad 6. .

A horizontal shaft 17 is passed between the plates 11 arranged on both sides of the pad support frame 12, and a hanging arm 18 is supported by this horizontal shaft 17. When the hanging arm 18 is swung, the pad support frame 12 is moved. It is designed to move in a straight line.

The means for converting the swinging motion of the hanging arm 18 into linear movement of the pad support frame 12 is to extend the end of the hanging arm 18 supported by the horizontal shaft 17, and to form an arc-shaped outer periphery of the extended portion 19. The extension portion 19 and the pad support frame 12 are connected by a check 721.

Note that the structure of the conversion means is not limited to this, for example, as shown in FIG.
An arcuate hole 22 is formed in the arcuate hole 22, and both ends of a connecting pin 23 inserted into the arcuate hole 22 are supported by the pad support frame 12, or as shown in FIG.
It is also possible to use a structure in which the extended end of 8 and the pad support frame 12 are connected by a link 24.

The hanging tool shown in the embodiment is different from the above-mentioned structure, and this hanging tool adjusts the dimension between the positioning pad 6 and the pressure pad 14 in accordance with the thickness of the wall to be set. When a wall is placed between 14, both pads 6.1
4 clamps the wall with the elasticity of the spring 16.

In order to adjust the spacing between the pads, the threaded rod 8 is rotated to move the pad support 3 along the support arm 1, and after the adjustment, the tightening nut 10 is rotated to tighten the nut 10. is brought into contact with the end face of the nut 7 next to the pad support 3 to prevent the pad support 3 from moving.

After the dimension adjustment work as described above, the hanging arm 18
When the pad support frame 12 is moved back in the upright direction, the space between the positioning pad 6 and the pressure pad 14 becomes wider. In this state, a part of the wall A is positioned between the pads 6 and 14, After that, when the swinging operation of the hanging arm 18 is released, the pad support frame 12 moves toward the positioning pad 6 due to the elasticity of the spring 16, so that the wall A is clamped between the positioning pad 6 and the pressure pad 14. The clamping force and contact friction force can temporarily fix the entire hanging tool.

After temporary fixing, when the hanging arm 18 is swung downward, the pressing cam surface 20 provided on the outer periphery of the extended end 19 of this arm 18 presses the back surface of the pad support frame 12, so that the pad support frame 12 moves to the side of the positioning pad 6, and as a result, the pressing force of the pressure pad 14 against the wall A is improved, and the entire hanging tool can be firmly attached to the wall A.

After the hanging tool is attached, the evacuation tool is suspended and supported from the end of the hanging arm 18 via a carabiner or the like.

By suspending and supporting such evacuation equipment, a downward load acts on the end of the hanging arm 18, which further increases the pressing force against the wall of the pressure pad 14, improving the stability of the hanging equipment. can be done.

As described above, according to this invention, the pressure pad provided opposite to the positioning pad is movable and moves in conjunction with the swinging of the hanging arm provided on the back of the pressure pad. It is removable and can be set by a simple action of swinging the hanging arm after positioning a part of the wall between the positioning pad and the pressure pad.

In addition, because the elasticity of the spring applied to the pad support frame allows the positioning pad and pressure pad to hold a part of the wall under pressure, there is no need to hold the hanging tool when swinging the hanging arm. , the swinging operation of the arm can be easily performed.

Furthermore, when the hanging arm is swung downward, the pressure pad moves to the side of the positioning pad and presses down on a part of the wall.In addition, the weight of the evacuation equipment hanging from the end of the hanging arm further pushes this hanging arm down. Since it swings downward, it can be mounted stably against a wall.
