Abstract

A personal rescue or escape chute comprises double walled chute sections 1, the sections are joined together to make a chute of the desired height along with a cooling water circulation pipe 4 with an outlet valve 3 at the bottom of the safety chute. The sections may have joints comprising of a countersunk joint assembly 9, rubber seal 10, lip flange and water joints 11. The joins may be fastened with nuts and bolts or may use wing nuts 7 clipped into brackets 8. Water is pumped up to an inlet valve 6, or an upper storage tank, which may also connect to the water mains and building water storage 14. The water travels through the cavity created by the double wall structure keeping the interior of the safety chute relatively cool, but if the water temperature in the safety chute rises above certain level then the warm water may be released out of the system. In case of power failure valve 2 can be opened on a slow drain out creating a water system whereby cold water will enter the system through the connection with the water mains or the building water storage.

Description

Water cooled Safety Chute.

The invention relates to emergency safety chute slide down.

There are many situation in which people get trapped, such as fire, earth quake, and any other disastrous and unforeseen situation where all the exit escape routes are blocked or are too dangerous to go down, therefore the only option will be to slide (5') down a water cooled safety chute, or perhaps be the first option being the fast way of getting to the ground and out of danger.

The invention seeks to provide a relatively cool, comfortable, safe and fast slide down to the safe level or all the way down.

According to one aspect of the invention there is provided a double wall cavity water filled safety chute with spring biased entrance I exit door on each and every floor of the building, a water inlet valve at the top safety chute and a water outlet valve at the bottom of the safety chute, a water pump, a water circulation pipe, a water release valve, a ventilation eiit, a cooling chamber, safety chute upper water storage tank (IOI which is also connected to the building water storage tank and the safety chute lower water storage tank.

The safety chute is joined by water tight joints on each floor starting from the basement or the ground floor extending all the way to the desired height, having left or right turn loops at the desired angle and the distance between each loop.

/ \ Advantageously in low rise buildings such as houses, offices, stadiums, schools, U hotels, a double wall running water safety chute connected to the building water storage tank and electric pump, will keep the water circulating by switching the onloff button manually and if for unforeseen reason a power failure occurs then simply release the water release valve situated at the bottom of the safety chute creating a water in / out system.

A fully automatic system with sensors for all high rise building where upon opening any door on any floor will trigger the whole apparatus into action simultaneously such as inflating air cushion platform in the basement or the ground floor, blowers blowing (ocO) cold and fresh air into the chute, chimney vents open, cooling system on, water pump on, creating a complete circulation keeping the interior of the safety chute relatively cool and comfortable even in extremely high temperatures, and if the water in the safety chute starts to get warmer or above certain degrees, the water release valve at the bottom of chute will open releasing the warm water out of safety chute at the same time fresh cold water from the mains and building water storage tank will enter into the system in the safety chute upper storage water tank.

Advantageously the safety chute for high rise buildings will be at least triple wall having water cavity and liquid set insulation, or a quadruple wall cavity having insulation on both sides of the water cavity and further heat resisting material can be added on the outside exterior surface of the safety chute. The joints on this chute will (2) have nuts, bolts, and washers to tighten the upper section with flange sitting into the lower countersunk section as will be the water nozzles sitting into countersunk holes.

A special float valve can be screwed into the entire safety chute nozzles which will (5) prevent the water pouring out if a certain section of the chute needs replacing.

Advantageously each section will fit within one floor with the joint either below the ceiling or above the ceiling through a cut out hole or open plan space area. The chute section will be moulded out of heat resisting nylon, rubber, plastic material in a single piece or number of pieces joined together, or metal fabricated and welded together, or even each single loop joined together with a door loop piece placed at the right level for easy entry into the chute.

Advantageously the safety chute will include at least one electrical cables system and at least one fibre optic system linked to all the sensors and all functional devices.

The safety chute connected to the water mains or building storage tank can have just one on/off water release valve within a convenient location on ground floor, in the basement or even in the reception area of a hotel, and for safety reasons one onloff water release valve outside the building to create a in!out watcr flow in the safety chute by releasing the water slowly out into the drainage system, while at the top fresh water is entering into the safety chute from the water mains and the main building storage tank.

(r 5') Advantageously the water release valve at the bottom of the safety chute is the most essential past of the apparatus for creating water in / out system in case of power failure, for cooling down the safety chute by releasing water out, and by closing the top water inlet valve all the water from safety chute canbe drained out for repairs.

Advantageously in a emergency one can slide straight down to any one of the safer floor below or all the way down, or one can use a little trolley with a pull up lever for braking and slowing down, or a special lithe mat with rubber strips on both ends for pressing down on them will act as braking and slowing down. (go')

Advantageously for slowmg down towards the lower end of the safety chute the loops can be set at lower degree angle, also to further reduce the speed of decent the interior surface of the last section can be rubber compound coated.

Advantageously this apparatus of the water cooled running water safety chute will save a lot of lives in the future even in a two storey house having just one section of the safety chute.

Advantageously the shape, size, design, angle, length, breath, width, and the distance between each loop, level of turning circle, angle of turning circle, amount of space available, manufacture of each section and the process of delivering to the site and erecting one section at a time will determine the final product.
