FR2521257A1 - Collapsible timber guard for cargo pallets - has spring-loaded cargo pin and angle stop for guard frame - Google Patents

Abstract

The pallet (15) is fitted with a collapsible timber side frame (7) to protect soft and perishable goods when stacked, during transport. The side frame (7) has an outer lining of sheet steel (6) to which is fixed an bracket (4) on the side and an angle bracket (5) at the base. The frame is hinged to the cargo pin (2) by a ring (1) which is fixed between the two angles. The frame can be laid flat and disengaged from the pallet. In the vertical position the angle (5) acts as a stop, ensuring the frame is positioned vertically.

Description

 The present invention resides in an apparatus fixed on a pallet of a cargo plane, making it possible, in addition to the current stowage by net launched on the goods and fixed to the pallet by stowage pins, to maintain the load so that it it no longer tilts laterally.

 Until now, the boxes of chicks, as well as those of vegetables, were stacked one on the other on an airplane pallet, up to a height of 1 m 50 to 1 m 80 depending on the height of the holds of the plane to be transported. These boxes were and still are held just by a net, stretched so that it sticks to the goods transported. This net is effective on hard loads (box or machine) but for transport in small tarton, it is much less. It is even less so if they are cartons of chicks, green beans or fresh fish, the boxes of which are wrapped in plastic bags. In these last cases, the boxes undergo a crushing and in addition for the fishes the boxes slide because of plastic. This crushing is done at the base of the loading by the weight of the load, and at the top if the net is too tight. This second aggravates the first. This compaction occurs during handling, and during transport to the aircraft.

Also, a net stretched correctly when making a pallet is already relaxed when it is loaded on the plane. Then, during the flight, this is accentuated with the landings, takeoffs, crossings of turbulence zones and the inclination of the plane describing curves. The net is then too loose and the load collapses on the first shock, this one no longer being maintained enough. This causes multiple problems 1. High mortality for the transport of chicks 2. Crushing of transported vegetables making them unsuitable for sale and well
safe refused by the recipient 3. This creates difficulties when unloading the aircraft or loading and
extra minutes to park an airplane are very expensive
to Companies.

 This invention helps prevent loads from overturning if the load settles (and it still settles) and the net relaxes. It also prevents the progressive sliding of the boxes. These devices by their design and their use in pairs are distributed on each side of the pallet (two, three or four pairs according to the weight of the goods to be supported: allow to maintain the load without crushing it. They play a little the role of bookends in a library.

 The attached drawings are divided into three plates.

 The first represents an entire device, front, back and profile.

 The second represents the full-size fixing system.

 Referring to plate 3/3 we have two devices A and B placed face to face, and fixed by the pins (2) in the rail (14) of the plane pallet (15). We take a rope (10) which we attach to the ring (9) of device A. We pass the other end of the rope (10) through the hole (11) of device A. We cross the pallet (15) with the rope (10) and pass it through the hole (11) of the appliance B. After the hole (11) we hold the rope (10) and make a loop (12) and pass the rope ( 10) in the ring (9) of the apparatus B and go back to the loop (12) in order to tension the rope (10) by an energetic pull, and to finally attach it.

 Attached, thus, the devices stick against the load without crushing it because they are held vertically by the angles (5) resting on the pallet (15). In addition, thanks to the cord (10) the two devices (A and B) hold each other and as soon as a force is made on one, a recall is made on the other thus preventing the load from tipping or sliding towards the interior.

 The number of devices to be placed on a pallet depends on the weight and the nature of the food to be transported. In addition it is possible to pass the rope at mid-height of the devices before going up that removing all possible flexibility of the wooden slat.

 These devices, in addition to their utility for transporting perishable freight in small cardboard boxes, can be used to tie up cargo in rolls such as pieces of fabric, carpets, rolls of carpet.

 The third shows two devices in place on an airplane pallet to explain their uses and the effect they have on each other, thus arranged.

 This device is made up of two parts, one in wood and the other metal which is used for fixing.

 The wooden part is a wooden slat (7) 1,500 mm long, 150 mm wide and 20 minutes thick. At different points of the batten (7) are drilled holes (11) 15 mm in diameter to allow the passage of a rope (10).

These holes (11) can be made at different heights depending on the height of the packages to be maintained.

 The metal part is made up of a sheet (6) 2 mm thick, 300 mm long and 120 mm wide. In it, there are 5 holes to allow the passage of 5 flat head bolts (8), one of which, in the middle of the sheet (6) is used to fix the ring (9) which will be used to attach the rope (10).

 To the sheet (6) is fixed the angle iron (4). This is riveted to the sheet (6).

The angle iron (4) is 2 mm thick, it is cold profile. Its length is -120 mm, the side facing upwards and connected to the sheet (6) is 40 mm, that on the horizontal is 20 mm. Another angle (5) of the same type, has the horizontal side of 40 mm and the vertical side, facing downwards of 20 ma. Depending on the type of plane pallet, it can be 30 or 35 mm. This vertical part, when the device is in position, plays a large role, it comes into contact with the plane pallet, thus preventing the wooden slat (7) from going beyond the vertical towards the inside of the pallet. This angle (5) is 150 minutes long.

 Between the two angles (4 and 5) is fixed the ring (1) of the lashing pin (2). To tighten it between the two angles (4 and 5) two holes are drilled to put two bolts (3) passing through the ring (1) holding it captive.

On the angle iron (5) are arranged four holes for passing four wood screws (13) thus connecting the base of the slat (7) to the angle iron (5) and giving strength to the fixing of the slat (7).

 The pin (2> is a small instrument such as it is found on the threads of the empty pallets. It is composed of the ring (1 attached to the axis of the pin (2) in a mobile way. On this axis a spring which presses on a sliding part which serves to block the pin (2 'on the rail (14) of the plane pallet (15>. The mobility of the ring l) on the axis of the pin (2> allows during 13 setting up the device e 'to facilitate this, to put the slat; 7) horizontally to be able to fix the pin (2) in the rail (14, of the pallet (15).

 These devices work in pairs. They must be placed on either side of the axvon pallet (15) and connected to each other by a rope (10).

Claims (2)

REX DICATI0N5  1) Device characterized in that the angle iron (5) prevents the latter from exceeding the vertical position when the latter is fixed to the pallet (15) by the pin (2) and thus makes it possible not to crush the load.  2) A method of using the devices, characterized in that the presence of two devices facing each other and connected by a rope, mean that, thanks to claim 1, these hold each other (A retains B and 8 retains A> thus taking up and down load like books in a bookend.
