摘要： PURPOSE:To make a fire hose inflatable in a cylindrical form for water running through thereinto in keeping it rolled intact at the time of using by forming a winding drum of a reel, suspended free of rotation in a frame, to make its circumference contractible in the radial direction of the reel. CONSTITUTION:A support rod (a winding drum of a reel 2) 5 is energized in the circumferential direction of a side plate 4 along a long hole 6 of this side plate 4 by a spring 7, and in the state that this support rod 5 is situated in an outer end of the long hole 6, a fire hose 12 being folded in flatness is wound around this support rod 5, thereby keeping it in storage. At the time of use, in this state of being rolled, water is made to run through this rolled hose 12 from a conveying hole 11 by way of a water supply port 9. With this water running through, the hose 12 rolled in plural layers on the circumference of the support rod 5 is inflated into cylindrical form in succession, while the support rod 5 is moved inward against resiliency of the spring 7. Thus, the hose 12 is inflable in the cylindrical form in a state of being rolled on the support rod 5 of the reel 2 as it is, and water is sprayed out of a discharge nozzle 13 at the other end of the hose 12 through the hose 12.

摘要： PURPOSE: To resist heat by providing a self-protective function such as to protect a hose by leaking water only in a part heated from outside without changing a basic structure of a weight-reduced hose. CONSTITUTION: In a weight-reduced hose where a watertight layer 2 is formed on an inside surface of a jacket 1 whose warp 4 and weft 5 are woven in a cylindrical shape, heat resistant work 3 is applied to the jacket 1, and the watertight layer 2 is formed of thermoplastic resin to be softened by heat transmitted through the jacket 1. Particularly, a softening degree by heat of the watertight layer 2 and a degree of the heat resistant work 3 of the jacket 1 are combined with each other so that the watertight layer 2 is broken without rupturing the hose when a heat resistant test is performed and water leaks from a surface of the jacket 1 and rupture pressure of the hose after this heat resistant test becomes equal to or higher than design working pressure when the heat resistant test by an A type fire model is performed in a condition where water pressure of 3kg/cm is applied to the hose, and proper water leakage is made obtainable only in a part with which a combustion material contacts among the hose.

摘要： PURPOSE:To make the titled hose superior in wear resistance and weather resistance and that favorable in handling properties, by a method wherein inside processing of a jacket is performed by immersing the jacket into a specific processing liquid prior to formation of a coating layer on the jacket and inorganic substance whose particles are sufficiently large is made to stick on the inside of the jacket through inside processing. CONSTITUTION:A jacket 2 formed by weaving warp and woof composed of long fiber thread into cylindrical state is immersed into a processing liquid 11, which is a mixed emulsion of colloidal silica with rubber or synthetic resin and having a mean particle diameter of less than 200mmu, in the inside of a processing liquid tank 10, which is pulled up through the processing liquid 11 and dried by passing through a hot air drying furness 12. In that instance, the colloidal silica of the inside of the processing liquid 11 entered into the jacket 2 aggregates to form spherical particles of silicon oxide. Then a coating layer of the rubber or the synthetic resin is molded on the surface of the jacket through extrusion by passing through the inside of a head 13 of an extruding machine. Then as the jacket 2, the coating layer is made into an inside lining layer 3 by turning over the inside and outside of the jacket 2 and a fire hose as a final product is obtained. With this construction, a process is simplified and the hose is turned superior in wear resistance and weather resistance.
