Description

[Detailed Description of the Invention] The present invention relates to a safety belt for a gradual descent machine that allows evacuees to slowly descend from a high place in a building in the event of a fire outbreak.

Conventionally, as shown in FIG. 1, when a descending machine 1 is equipped with a descending cable 2 connected to both ends with safety belts 6, and a pulley with a centrifugal brake through which the intermediate part of the descending cable passes, the safety belt 6 and Since it is normal to wind the descending cable 2 around a rubber drop reel 7,
The bifold safety belt 6 wound around the inner end of the reel 7 is tightened by the descending rope 2 wound around the outside thereof.

On the other hand, since the belt 3 of the safety belt 6 is triple woven from cotton or synthetic resin threads, the mounting bracket 8 of the slow descender 1 installed at the evacuation exit of the building should be used in the event of a fire.
When both safety belts are suspended via the descending rope by dropping the drop reel 7 outdoors as shown in Fig. 1, the belt 3 of the lower safety belt often clings tightly to the folded part. In some cases, the safety belt 6 may remain folded, and in this case, when the safety belt 6 on the lower side of Figure 1 rises to the evacuation exit, it should normally open into a ring shape and hold the evacuee's armpit. There is a danger that a panicked evacuee could grab Belt 3 and fall down, which is extremely dangerous.

The present invention addresses this problem by connecting each end of a descent cable that frictionally passes through a slow descent machine.
A safety belt made of cloth is wrapped around a drop reel and stored together with the descending rope, and the descending rope 2 is attached to the descending machine 1.
The present invention is characterized in that a flexible band-like member 4 that constantly urges the belt to expand is bonded to the lower back end portion 3a of the belt 3, which is suspended and supported through the belt.

2 and 3 show an embodiment of the present invention,
The safety belt 6 is constructed by holding the bottom side of a hanging ring 10 engaged with a connecting ring 9 to the descending cable 2 with both ends of a cloth belt 3 similar to the conventional one, and tightening both holding parts with bolts and nuts 11. A fastening ring 12 is slidably fitted to the belt 3, and the outside of the back contact portion 3a of the belt 3 is made of one type of material similar to that of the belt, such as leather, rubber, etc. Alternatively, a plurality of types of flexible band-like members 4 are glued or sewn while the belt is in a linearly unfolded state. In the illustrated case, a thin plate-shaped or linear weak belt-expanding spring 5 is sandwiched between the back rest portion 3a and the belt-like member 4 to further increase the belt-expanding ability.

The present invention has the above-mentioned configuration, and when storing the slow descent machine, the safety belt 6 and descending rope 2 are wound around the drop reel 7 while preventing the band member 4 from being folded. That is, as shown in FIG. 4, only the belt 3 at one end of the strip member 4 is folded, and the folded part A is inserted into the long hole 14 provided in the body part 13 of the reel 7. The part A and the torso part 13 are locked together, and a safety belt or descending cable is wrapped around the torso part.

For this reason, folded portions B and C are formed in the middle of the belt 3, but in the usage state where the safety belt 6 is suspended and supported by the descending machine 1 via the descending cable 2 as shown in FIG. The folded portions B and C help the belt 3 to expand, which is convenient.

According to the present invention, when the safety belt 6 is suspended and supported by the descending cable 2 in order to use a slow descent machine, each belt 3 is attached to the belt-like member 4 attached to the safety belt 6 as shown in FIG. 2. Because it will be expanded to a certain extent,
There is no fear that the tightening ring 12 will fall under its own weight along the belt, and there is no fear that an evacuee who is descending by grasping both sides of the folded belt 3 as in the past may slip off the belt. effective.
