Description

DETAILED DESCRIPTION OF THE INVENTION The purpose of this invention is to prevent tragic deaths caused by people losing their escape and falling to their deaths due to fires in high-rise buildings. In other words, when you have no way out in an emergency such as a fire, put this invention on your back, tighten your safety belt, hook the wire hook in place, hold the brake grip with one hand, go outside and tighten the brake grip. It descends at a speed of about 100,000 yen, stops midway, and rises at will. Regardless of gender or weight difference, even women and children can evacuate in an extremely simple and safe manner. Also, it can be used for work. It also provides an extremely useful fall life preserver.

The present invention will be described in detail below with reference to the drawings. As shown in FIG. (this may be omitted in the case of Attach the other end to the outside of the drawer opening 14 (see Figure 3) drilled in the upper part of the case 1, and securely attach the hook 13. As shown in Figure 5, the fringe 35 and the fringe 34 are fitted ( The braking gear 6 (not fitted in case of lowering only) and the small gear 5 (see Fig. 1) are integrated into one unit, and as shown in Fig. 2, the small gear 5 is inserted into the support shaft 7 and fixed. A chain wheel formed by meshing the gear 5 with the drum gear 3, extending one end 7' of the support shaft 7 into the case 1', and fitting a fringe boss 38 and a fringe 37 as shown in FIG. 36 (excluding when lifting is not required) is inserted into and fixed to the support shaft 7' so as to rotate opposite to the brake gear 6, and provided around it for free rotation via support shafts 40 and 40'. The chain 41 is wrapped around the chain wheel 36 through the groove wheel 39.39'',
(The chain wheels 36, 34 and 37 are commonly used in chin blocks, bicycles, etc., and can be designed very easily by engineers in the relevant department, so detailed diagrams are not provided.
□ and explanation omitted) When pulling out the wire 12, the chain wheel 36 is stopped by the action of the flex 37, and the chain wheel 36 is pulled out with both hands via the chain 41- (a small entrainer may be used).
When pulling the wire 12 and rewinding it to the drum 2, the braking gear 6 is continuously rotated so that the flex 34 works and stops, and the chain 41 can be pulled with both hands and raised easily (similar to a chin block). As shown in FIG.
The control plate 8.8" is set for free rotation through the A tooth feed, 9 degrees protruding from one end of the control plate 8.8", meshing with the braking gear 6, and the B gear 10.10 protruding from the other end. " is placed just before meshing, and according to the rotation of the brake gear 6, A tooth feed, 9" and B double feed 10.
Furthermore, a pawl 24 is provided around the ratchet gear 27, one end of which is freely rotatable around a case 25, and a tooth tip 24 of the other end. ' is meshed with the ratchet gear 27, and one end of the spring is connected to the regular size 24" drilled in the middle, and the other end is connected to the regular size 24" drilled in the case 25' (not shown). 24"
The ratchet gear 27 is tightened to prevent rotation of the ratchet gear 27, and the handshake 30 and 31 can be freely opened and closed via the support shaft 32. One end of the tube 28 is fixed to a small hole 28' (not shown) drilled in the case 1, and the other end is fixed to a wire 290 at 31°.
8. It is fixed to the regular size 33 drilled on the lower side of the tooth tip 24'' through a small hole 28'' (not shown), and the tooth tip 24'' can be attached and detached from the ratchet gear 27G by opening and closing the brake grip. , the ratchet gear 27 can be freely rotated and stopped G
As shown in FIG. 3, metal rings 15.
Attach metal rings 17 and 17' to both lower ends of 15' and metal rings 18 and 18' to both sides of the lower side, and attach back bands 16 and 16.
' One end of gold ring 15.15', the other end of gold ring 17.1v
Connect the case 1 to the gold ring 18' with both hands in place, connect one end of the band 19 to the metal ring 18', and connect one end of the band 22 to the metal ring 18'.
A retaining ring 21 is inserted into the other end to secure a buckle 20, and the buckle 20 is inserted into the buckle 20 from the tip of the band 19 and tightened so that it can be fastened as a safety belt. It is also possible to install a metal ring on the bag or a seat band (not shown). Tighten the safety band on your back, hook the hook 13 indoors or somewhere else, grab the brake lever in one hand, go outside and hang, and when you tighten the brake lever, the rotational speed of 24゛ will be released, and you will be able to quietly maintain a moderate speed. (The speed of descent can be adjusted by increasing or decreasing the number of teeth on the gear.) You can also stop midway, or stop by releasing the brake grip) If you want to reverse rotation by pulling the chain 41 with both hands, use a similar principle to Chinbu 1'7. It is possible to climb up at will from any high-rise building, regardless of gender, regardless of weight.
This also allows you to safely descend and evacuate. Therefore, if this invention is kept on hand for emergencies, the tragic death caused by a painful jump caused by a fire in a high-rise building can be completely prevented. Moreover, it has a wide range of uses for work and is a huge contribution to society.
