Abstract

The cargo deck for the cargo hold of an aircraft has several mounting profiles (10) which are fitted in the longitudinal direction of the aircraft and in which are mounted functional elements such as rollers (31-35), ball elements (53), locks (40,52), PDUs (51) and floor elements. The mounting profiles when viewed over the width of the cargo hold have identical spacings with identical components (20,21) fitting accurately between them. An odd number of mounting profiles is provided, especially 5, 7, or 9, but preferably 7.

Description

The The invention relates to a support roller according to the preamble of claim 1 and their use.

From the DE 2908400 A1 For example, an arrangement for a cargo hold floor of a (wide) aircraft is known in which a total of six rows of mounting profiles are mounted in the longitudinal direction of the aircraft. In the mounting profiles support rollers and locking elements are mounted. The arrangement of the mounting profiles is such that two containers side by side find space and sit at the edge and center on the support rollers. For locking the container in a direction transverse to the aircraft longitudinal axis corresponding locking elements are provided between the central mounting profiles.

at This arrangement, it is considered disadvantageous that the support rollers each mounting profile only one row at a time (in aircraft longitudinal direction) of containers or pallets can be used for the next row of containers, pallets or the like items of freight is Separate mounting profile needed with carrying rollers mounted therein.

Of the Invention is based on the object, a support roller of the above to further develop this type of knowledge so that a more versatile Availability is ensured at low construction costs.

These Task is solved by a support roller according to claim 1. Especially The object is achieved by a support roller for mounting in a mounting profile a cargo compartment floor of an aircraft cargo space, wherein the mounting profile side walls has and in an interior of the mounting profile locking elements for securing containers, pallets or the like freight packages mountable are solved by that at one through the side walls passed through the mounting profile Axle two outer rollers outside the interior of the mounting profile are rotatably mounted. Through this Arrangement it is possible Two rows (in aircraft longitudinal direction) by means of a single mounting profile to mount from idlers.

Preferably is on the axle in the interior of the mounting profile one (further) Inner roller mounted. This will improve the support of a Containers then reached when not only with its edge zone over one the two outer rollers, but with its entire floor over both outer rollers and the inner roller moves.

Preferably are the external roles each in a carrying cage mounted, on the one hand to the associated side wall of the mounting profile is fixed and on the other hand has an outer wall, in which the axle is attached with an end portion under support. In spite of the small additional expenditure for the assembly of external rollers results in a significantly increased Strength of the overall arrangement, the support profile substantially can be kept free of bending moments.

Of the carrying cage preferably has an upper surface with a central recess through which the outer roller protrudes. This achieves an overall improved protection against damage.

The upper surface is preferably to the outer roll inclined upward so that when starting a Containers is ensured that this ascends to the role. Farther indicates the upper surface of the cage preferably a rounded outer contour with side edges on, which in the direction of the respective associated side wall of the mounting profile diverge. On the one hand, this results in an increased stability of the overall arrangement, On the other hand, this measure also increases security achieved against catching cargo on the cage.

The outer rollers are preferably much narrower than the interior of the mounting profile or an optionally mounted there inner roller. This will on the one hand an increased stability due to shorter axis length achieved, on the other hand, in spite of this measure is only an external role guided Container not overloaded, since he's over with his edge the outer roll moves, So with an area in which the usual containers or pallets reinforced are formed.

Especially preferred is the use of the support roller according to the invention in a mounting profile, that (especially single) in the middle of the cargo hold floor of a Aircraft mounted, designed as a roller conveyor and with cross bars is provided for locking pairs of containers or pallets or like pieces of freight along the middle of the cargo hold floor. In this use can a mounting profile can be saved, which is not only in terms the construction cost, but especially in terms of weight savings is particularly advantageous.

Preferred embodiments of the invention From the dependent claims and the following description of exemplary embodiments, which are explained in more detail with reference to figures. Show here

1 a front view of a mounting profile with rollers and wedges of containers,

2 a view along the line II-II 1 .

3 a view along the line III-III 2 .

4 a perspective view of a mounting profile with carrying rollers and bolts, and

5 a plan view of a portion of a cargo hold floor.

In The following description will be for the same and the same Parts used the same reference numerals.

As in the 1 to 4 shown has a mounting profile 10 side walls 11 and 12 on top of a floor 13 protrude upwards. high edges 14 and 15 the side walls 11 and 12 are "flanged" to increase the flexural rigidity.

On the side walls 11 . 12 and on their outer surfaces are cages 20 by means of a flange 21 mounted, over rivets 26 on the side walls 11 . 12 is attached. The cage 20 continues to point perpendicular to the side walls 11 . 12 of the mounting profile 10 from the flange 21 protruding side cheeks 24 . 25 as well as one of these side cheeks 24 . 25 connecting outer wall 22 on, so that there is a closed, rigid box. The upper edges of the outer wall 22 and the side cheeks 24 . 25 go into an upper surface 23 about which a cutout 27 having. This upper surface 23 is on the one hand rising towards the middle (see 2 ), on the other hand, it has a peripheral edge to the outside, from the mounting profile 10 is converged progressively and rounded at its corners.

Through the side walls 11 . 12 , the flanges 21 and the outer walls 22 of the two exactly opposite cages 20 is an axis 34 passed through and secured by end snap rings or the like. On the axis 34 are on the one hand external roles 31 and 32 and on the other hand, an inner roll 33 rotatably mounted, the outer rollers 31 . 32 and the inner roll 33 have identical diameters and the outer rollers 31 . 32 through the cutouts 27 the cages 20 to stand up.

As in 5 are shown on a cargo hold floor 50 all in all 7 Mounting profiles mounted in the longitudinal direction of the aircraft, namely a middle mounting profile 10 , two edge mounting profiles 10-3 and in between inner mounting profiles 10-1 and 10-2 , In the inner mounting profiles 10-1 and 10-2 are PDUs 51 and bars 52 mounted, which secure container against forces in the aircraft longitudinal direction. In addition, in all mounting profiles (inner) rollers 33 and ball elements 53 (please refer 4 ), so that arise roller conveyors.

In the middle mounting profile 10 , which with the outer rollers 31 . 32 provided are bolts 40 attached, which serve to secure the cargo in the aircraft transverse direction. As in 1 and 4 indicated, have these bars 40 nose 41 . 42 which are directed to the two sides. This way containers can 1 . 2 (please refer 1 ) with their locking edges 3 . 4 by means of the bolt 40 or its noses 41 . 42 be secured. The arrangement of the outer rollers 31 . 32 Here is such that the container 1 . 2 with their edge stripes 5 . 6 on the outer rollers 31 . 32 (barely) rest, the inner roll 33 however do not touch. In this way, two adjacent containers on the cargo hold floor (see 4 ) by means of a single mounting profile 10 and the outer rollers attached there 31 . 32 be safely supported. Then, when a container of higher width is loaded into the hold or for some reason a narrower container is not transported at the edge but rather in the middle, the inner roll comes 33 to the effect, which can support such a container on its relatively soft ground due to their high width. The outer rollers 31 . 32 in this case give an additional support surface.

From the above it is apparent that the use of the carrying rollers described here not only brings a saving in effort and weight with it, but also by the arrangement of the bolt 40 achieved within this middle mounting profile over the prior art, a significant advantage.
