RU2290344C1 - Floor carpet coat for cargo-and-passenger cabin - Google Patents

Abstract

FIELD: aeronautical engineering; floor coats; conversion of cargo cabins into passenger ones; sea and land transport facilities.

SUBSTANCE: proposed floor coat has carpet, stiffening members keeping carper from deformation, fasteners for securing easily removable carpet and photo-luminescent tapes-indicators of emergency escape. Carpet is made in form of strips connected by means of stiffening members made in form of longitudinal plates at longitudinal clearances between strips where emergency escape photo-luminescent tapes are located and secured on stiffening members. Floor carpet coat may be rolled for stowage.

EFFECT: extended operational capabilities.

Description

The invention relates to aircraft, and in particular to the flooring and floors of aircraft, and can be used for the conversion of cargo cabs into passenger cabins. The present invention can also be used on marine and land vehicles.

A technical solution is known, published in the journal "Aviation week and space technology", T.97, No. 24, 11.12.72, p. 37-39, in which the cabin of a transport aircraft contains a floor on which they roll up and on which passenger blocks are fixed compartments equipped with flooring, chairs, luggage racks, etc.

The disadvantage of this technical solution is the large weight, because the floor, walls and ceiling are duplicated by the aircraft floor, walls and ceiling, the fastening to the floor of the compartment blocks must be powerful, this invention can only be used on aircraft with a ramp and high ceilings.

Known flooring US No. 3938764, 64 C 1/18 (US C1. 244/117), containing the floor, carpet, mounted on a stiffness, made in the form of a panel that is attached to the floor by fixing elements.

The disadvantage of this technical solution is the large weight of the device and the fact that, using this invention, the height of the passage in the passenger cabin of the aircraft will decrease, because the panel has a thickness, as well as the fact that the storage and installation of such a device is difficult due to the large dimensions of rigidity, made in the form of a panel.

The closest is the CAF-T-GLO flooring (www.stagaerospace.com), containing photoluminescent tapes indicating emergency exit from the aircraft. The floor covering includes a patch panel glued (around the entire perimeter of the panel) to it with a soft corrugation carpet and with smooth sections on which photoluminescent emergency exit tapes are glued.

The disadvantage of this device is that the carpet, to prevent deformation, is glued to the stiffness, made in the form of a patch panel. The patch panels have a thickness, and this reduces the height of the aisle, as well as the fact that a carpet having soft corrugation on the outer surface should be made with smooth sections on which photoluminescent index tapes are glued. This increases the cost of manufacturing (manufacturing) the device. Storage, installation and dismantling of such a device is difficult due to the large dimensions of the stiffness, made in the form of patch panels.

The objective of the invention is to expand the operational capabilities of the aircraft by converting the cargo floor into a passenger one, by placing the floor carpet while maintaining the passage height in the passenger cabin, equipping the floor with photoluminescent emergency exit tapes technologically combined with the floor carpet, and ensuring the compact laying of the device when storage and transportation.

The invention is illustrated by drawings, where:

figure 1 - floor carpet depicted in the interior of the cabin;

figure 2 - compact laying of the floor carpet;

figure 3 - floor carpet (in the foreground, one element of attachment to the floor is removed, the structure of the floor carpet is visible);

figure 4 - assembly diagram of the floor carpet company "CAF-T-GLO".

The floor carpet of the cargo and passenger cabin consists of carpet strips 1 interconnected by means of stiffness 2, made in the form of plates, so that photoluminescent tape indications 3 of emergency exit are glued to the resulting gaps between the strips 1 on stiffness 2. The floor covering is fastened with fasteners 4 to the floor 5.

Thus, the passage between the rows of chairs is equipped with a floor carpet with photoluminescent tapes-indicators 3 emergency exit with the possibility of converting the cargo compartment into a passenger.

For storage and transportation, the cargo carpet floor is made with the possibility of transformation into a compact laying in the form of a roll. This is ensured by the fact that the stiffness 2, made in the form of longitudinal plates, is performed only in the longitudinal direction, along the floor carpet, and in the transverse direction, flexibility is maintained.

Installation of the device is as follows. Compact laying of easily removable carpet is laid on floor 5 and oriented along the passenger cabin of the aircraft. Carpet strips are unfolded and straightened 1. An easily removable carpet around the perimeter is fixed to the floor by 5 fasteners 4. During operation, the stiffness 2 connecting the carpet strips 1 prevents the carpet strips from deforming 1. Photoluminescent signposts 3 emergency exit ensure safe evacuation of passengers because indicate the position of the passage between the seats and the direction of movement when the lights and smoke are off.

In the manufacture of the proposed floor carpet, the carpet strips 1 are cut from the linear material of the carpet, and smooth sections for gluing photoluminescent tapes-indicators 3 emergency exit are structurally formed on stiffness in the form of plates 2, because carpet strips 1 are glued with a gap - this reduces the cost of production of the proposed device, while improving the manufacturability of the device.

The proposed floor carpet for the cargo and passenger cabin allows the cargo floor to be converted into a passenger one without reducing the passage height in the cargo and passenger cabin, to technologically combine the photoluminescent emergency exit tapes with the carpet, and also to store the cargo and passenger cabin floor carpet for compact storage in a compact roll form .

Claims (1)

The floor carpet of the cargo and passenger cabin containing the carpet, stiffnesses that hold the carpet from deformation, and fastening elements for the easily removable carpet to the floor, photoluminescent tapes indicating emergency exit, characterized in that the carpet is made in the form of strips connected by stiffness made in the form of longitudinal plates, forming longitudinal gaps between carpet strips, in which photoluminescent emergency escape tapes are placed, fixed on stiffness, made in the form of longitudinal Lastin, wherein the floor carpet cargo cabin is configured to transformation during storage and transportation in a compact folding into a roll.
