Abstract

Disclosed is a life rope. By the life rope, a person can escape from windows or balconies entirely depending on personal abilities without any aid. The life rope comprises an enough long rope and a specially-made speed reducer. Core parts of the life rope are an oxford block and a cast iron slider which are sandwiched between two steel plates, and two screws are arranged additionally. With the aid of action of two pulleys, the life rope penetrates the oxford block for three times so as to increase contact area and friction force. The two screws are screwed up to push the cast iron slider to exert pressure to the oxford block, so that the oxford block tightly holds the rope. When the pressure is high enough, the speed reducer and the life rope can be fixed relatively. If the screws are unscrewed, the pressure is lowered, the oxford block restores gradually depending on self elasticity, and then the friction force is decreased. When weight of a human body attaching to the speed reducer is larger than the friction force between the oxford block and the rope, the speed reducer and the human body start descending along the rope; and descent speed can be controlled to a certain extent by means of adjusting tightness of the screws, and descending can be fast, slow and stoppable.

Description

Life line

Abovestairs people live, just in case breaking out of fire downstairs and there's nowhere to run, rescue aid can not arrive in the very nick of time or highly can't reach and during threat to life, use life line can allow the people under the situation without any the foreign aid, relies on individual's ability from window or balcony escape fully.Allow the people from the eminence safe falling to ground, realize saving oneself.If rope falls short of, also can temporarily rest on aerial in order to try every possible means to enter floor nearby or wait for relief.

One. the technical scheme of control sinking speed.Life line is made up of a sufficiently long rope and the special decelerator of a tool.Its core component is that a Cowhells piece and a cast iron slide block of being clipped in two steel plates add two screws.Effect by two pulleys makes life line pass the Cowhells piece 3 times, and purpose is to increase contact-making surface and frictional force.Tighten two screws, promote the cast iron slide block and exert pressure to the Cowhells piece, allow the Cowhells piece tightly embrace rope.When pressure was enough big, decelerator and life line just can relative fixed.If loosen screw, pressure reduces, and the Cowhells piece relies on the elastic force of self to restore to the original state gradually, and frictional force also reduces thereupon.When being affiliated to human body weight on decelerator greater than the frictional force between Cowhells piece and the rope, decelerator and human body just begin downward landing along rope.The degree of tightness of adjustment screw can be controlled the speed of landing to a certain extent, can can stop slowly soon.See accompanying drawing for details.Life line proposes two kinds of models of size, and large size can use for three-person household (husband and wife and a child), and is small size for single use.

Two. the using method of life line.Life line is a kind of being fit to from the special implement of window or balcony escape.To on the window abutment wall that is fit to escape, about 2 meters eminences be welded with a semicircular iron hoop on the plate, for fixedly life line special use with iron expansion bolt grappling one block plate earlier before the use.Screw on the decelerator can not be tightened at ordinary times, allows the Cowhells piece in the raw.Could use in the time of only must escaping in that fire and genuine entail dangers to life have taken place really.The method of using is: at first two screw-drivings on the decelerator, be screwed to appointed positions 1..2. fasten seat belts.The safety belt that arranges on the decelerator has three circles.Two following circles are enclosed within the root of two thighs of human body respectively, and a top snare is in the oxter, and the position of decelerator is in the front.3. there is one section about 3 meters long rope the top of decelerator, is through it among the pre-buried bail on the wall and beats an individual fast knot and fix.The length of rope is suitable.When human body climbed out of windowsill, human weight just dropped on the safety belt.4. the rope tied is untied and tossed out of the window and allow its vertical naturally ground, make a call to a knot at the end of rope, can prevent decelerator disengaging rope like this and cause danger.The middle part that is also noted that rope does not allow knotting, otherwise can't land down.5. human body can climb out of window and allowed own unsettled hanging on the life line this moment.6. left hand is firmly grasped the decelerator of front, and the right hand is held screw, slowly unscrews screw, allow hang over decelerator on the life line, under the effect of human body weight to lower slider, until dropping to ground.

Three. other purposes and the value of life line.Life line is except residential building can be used, as long as other have people's place equally also can use as if breaking out of fire.In addition can also be in the recreation ground exploitation as the tourist recreation campaign item, the enjoyment that allows tourist experience high-altitude rope fall is tempered people's courage and the ability of manoeuvre high-rise life saving.The life that rescues the people when fire is given in the appearance of life line has been opened up new approach.Be equipped with a last tool life line and increased insurance together with regard to equaling to the life of preciousness.Rescued human life just in case use, that just is worth huge.

Claims

1. life line is made up of a sufficiently long rope and the special decelerator of a tool; Its core component is that a Cowhells piece and a cast iron slide block of being clipped in two steel plates add two screws.Effect by two pulleys makes life line pass the Cowhells piece 3 times, and purpose is to increase contact-making surface and frictional force; Tighten two screws, promote the cast iron slide block and exert pressure to the Cowhells piece, allow the Cowhells piece tightly embrace rope.When pressure was enough big, decelerator and life line just can relative fixed.If loosen screw, pressure reduces, and the Cowhells piece relies on the elastic force of self to restore to the original state gradually, and frictional force also reduces thereupon; When being affiliated to human body weight on decelerator greater than the frictional force between Cowhells piece and the rope, decelerator and human body just begin downward landing along rope; The degree of tightness of adjustment screw can be controlled the speed of landing to a certain extent, can can stop slowly soon.Life line proposes two kinds of models of size, and large size can use for three-person household (husband and wife and a child), and is small size for single use.
