Description

The invention relates to aircraft, in particular to the equipment of aircraft for the transportation of goods, as well as to the equipment of passenger cabins of aircraft, and can be used to transport goods in vehicles, to place personal belongings of passengers inside the aircraft, as well as to separate classes in the passenger the cabin.

Known luggage shelf of a vehicle, mainly an airplane [US patent No. 4907762, class. B 64 C 1/20, B 64 C 1/22, publ. 03/13/90. U.S. Patent Documents], placed along the side of the vehicle, which is divided into individual compartments using dividing walls, and each of these compartments is closed with a corresponding lid.

The disadvantage of this device is the design complexity due to the fact that the edging element of the shelf and the guide rail are separate elements of the design of the shelf.

Known movable partition device for classifying the passenger compartment of the aircraft [WO 00/56601, cl. B 64 D 11/00, publ. 09.28.00, PCT Gazzete], which is attached to a guide rail located along the passenger compartment. This rail serves as a support for the rollers that make up the partition wall fastening mechanisms, which are designed to move the partition along the passenger compartment. After moving it is fixed in a specific position.

The disadvantage of this device is the design complexity due to the fact that the functions of the edging of the luggage rack and supports for securing the partition perform various elements.

A device for dividing into zones of the passenger compartment of the aircraft [WO 99/38771, cl. B 64 D 11/00, publ. 08/05/99, PCT Gazzete], containing a partition for zonal division and a longitudinal rail in which the partition has the ability to move.

This device has an inconvenience of operation due to the fact that the device for moving the partition of the aircraft cabin is located in an inaccessible place under the luggage rack above the passenger seats, and is not an integral part of the luggage rack. This can lead to failure of the mechanism due to jamming of the partition in the guide rails, which are located in an inaccessible place in the passenger compartment.

Closest to the invention in terms of technical nature, the intended purpose, the result achieved, and selected for the prototype, is a combination of the luggage rack with the ceiling of the passenger cabin [WO 99/38771, cl. B 60 Q 3/02, B 64 D 11/00, publ. 08.09.90, PCT Gazzete]. Elements associated with the luggage rack of this combination are located along the passenger cabin of the aircraft above the passenger seats. Each of these elements contains restrictive ribs and support plates forming a closed cavity. These elements play the role of longitudinal guides, in which the partition of the cabin has the ability to move. Elements are also attached to the shelf, which perform the function of fringing the luggage shelf, and also create a barrier against the sliding of luggage placed on the shelf.

This known device has several disadvantages:

- the complexity of the design due to the fact that the longitudinal guides and the fringing elements of the shelf are made in the form of individual parts that are mounted on the bottom of the luggage rack and are not included in its composition;

- the high cost of manufacturing longitudinal elements of the cabin due to the increase in the manufacturing cycle, the amount of necessary equipment and material from which the structural element of the luggage rack is made;

- the complexity of the installation, maintenance and repair of a complex of longitudinal elements, namely, guides and fringing elements, due to the presence of a large number of fixing joints. That is, each part of the complex is fastened with several fasteners, and for removal, respectively, it is necessary to disconnect each fastener connection.

These disadvantages of the prototype lead to a complication of the design, increase the manufacturing cycle and reduce the ease of installation and operation of the entire passenger cabin of the aircraft.

The basis of the invention is the task of simplifying the design by creating a single universal element that provides the functions of the entire complex of longitudinal elements of the passenger cabin of the aircraft. Namely:

- the function of edging the bottom of the shelf;

- the creation of an obstacle against the slipping of baggage;

- ensuring the fastening and movement of the walls of the cabin;

- ensuring the placement of information.

The basis of the invention is also the task of reducing the cost and duration of the manufacturing process of the device due to the fact that the universal longitudinal element is manufactured using an extrusion installation and, therefore, requires the use of less metal.

In addition, the task was set to simplify installation, maintenance and repair of the structure by simplifying the removal or fastening of the luggage compartment trim element.

The tasks are solved in that the trim element of the luggage compartment of the aircraft, placed along the passenger cabin of the aircraft above the passenger seats, contains restrictive ribs and base plates. According to the invention, the fringing element has three cavities, the transverse section of the element comprising one open and two closed loops defining said cavities. The open loop follows the shape of the corresponding loop of the airplane’s luggage rack to cover the bottom of the shelf with two sides of the shelf by means of support plates and then fasten them to the shelf with fasteners, such as screws. One of the element cavities is intended to be placed in it after removing the lintels of the vertical and horizontal fastening elements of the passenger compartment passenger compartment, installed with the possibility of movement in it along the support plates. The element also includes a support plate designed to accommodate a clamping element thereon with information printed thereon, which is mounted to move along this support plate. The element also contains a support plate, which creates an obstacle against the sliding of luggage from the shelf.

The claimed invention allows to simplify the design due to the fact that it is made in the form of a single universal element, which provides the functions of the whole complex of longitudinal elements of the prototype. That is, the luggage compartment edging element is a support for the side walls of the shelf, it borders the free edge of the bottom of the shelf, creates an obstacle against the slip of the baggage, and in the closed cavities of the element the movable supports of the partition of the airplane cabin are placed, which ensures its movement along the passenger cabin.

The invention reduces the cost and duration of the manufacturing process of the device due to the fact that the element is manufactured by extrusion. That is, with the help of simple equipment, namely, a die, which repeats the configuration of the structural element of the luggage rack. This also allows to reduce the amount of metal from which the element is made, since the coefficient of use of the material of the invention is equal to one.

The invention allows to simplify the installation, maintenance and repair of the entire complex of parts of the passenger compartment due to the fact that several elements are replaced by one universal element. This allows you to reduce the number of fasteners, provides a simple approach for installation (dismantling). That is, the universal element, which is the subject of the invention, provides the functions of several elements of the prototype. Namely, an element of edging of the bottom of the shelf, a guide for moving the partition of the cabin, an obstacle against the sliding of luggage, as well as an element that is designed to place information on it in the passenger cabin, for example, numbering of passenger seats.

Figure 1 shows a cross section of a border element of the luggage compartment of an airplane; figure 2 is a General view of the location of the border element in the luggage compartment of the aircraft.

The proposed element trim the luggage shelf (see figure 1) has three cavities A, B, C, and the cross-section of the element includes two closed circuits that bound the cavity A and B, and an open circuit bounding the cavity B. Cavity A, B and C contain base plates G, D, E, Zh, Z, I1, I2, K1, K2 and restrictive ribs that form surfaces M, L. On the base plate Zh of cavity A, the clamping element with the information applied thereon can move B has the ability to move the movable support of the partition walls of the aircraft eta. The circuit bounding the cavity B repeats the shape of the corresponding contour of the luggage compartment of the aircraft with the possibility of further fixing on it. The support plate E edges the edge of the bottom of the shelf with the possibility of creating an obstacle against the sliding of luggage.

The structural element of the luggage rack 1 is placed along the passenger cabin of the aircraft and is attached to the bottom 2 of the luggage rack of the aircraft, designed to accommodate baggage 3 and having a lid 4 for closing or opening the shelf (see figure 2).

The invention is intended for edging a shelf, creating an obstacle against the sliding of baggage on a shelf, for securing a clamping element with information printed on it, for securing and securing the movement of a partition of a passenger compartment of a vehicle, and also for stiffening the free edge of the bottom 2.

Each surface of the ribs and supporting plates of the element have their own purpose, namely:

- the base plates G and D of the cavity B are used to cover the bottom of the shelf 2 from two sides, followed by fastening with fasteners, for example, screws;

- the supporting plate E is designed to prevent the luggage from sliding off the shelf;

- the supporting plate W is a supporting plate for accommodating the clamping element with the information applied thereon;

- support plates I1, I2, K1, K2 in the cavity B serve as support, respectively, for the vertical and horizontal fastening elements of the partition walls of the passenger compartment.

The invention also performs a decorative function. That is, it is a transition element from the predominantly vertical lines of the contour of the luggage compartment lid cover 4 to the predominantly horizontal lines of the contour of the aircraft side lining elements that are under the luggage rack. This decorative function is performed by the surface M.

During installation of the partition walls, the jumper on the surface area A is removed. Thus, the free edge of the shelf is closed from damage and, in turn, cannot injure passengers with barbs and chipped edges that may appear during interaction with luggage. At the same time, the invention also performs a power function. That is, it gives rigidity to the free edge of the bottom of the shelf 2, linking it to the extreme side walls of the luggage rack and the central jumper (if it is provided for by the design of the shelf).

Thus, the claimed invention allows to simplify the design by creating a single universal element, which provides the functions of the whole complex of longitudinal elements of the passenger cabin of the aircraft. That is, the functions of edging the shelf, creating obstacles against the sliding of luggage, and securing and moving the partitions of the cabin. The invention allows to reduce the cost and duration of the manufacturing process, as well as the amount of metal from which the structural element of the luggage rack of the aircraft is made, due to the fact that the edging element is made by extrusion. The invention provides simplification of installation, maintenance and repair of the structure while reducing the number of fasteners, which provides a simple approach for installation (dismantling).
