Transport Pallet

Abstract

Transport pallet consisting of a first and second opposite short side and a first and second opposite long side. The bearing surface is constituted by a framework consisting of a number of mutually parallel extending elongate ribs and a number of mutually parallel extending transversal ribs extending perpendicularly to the elongate ribs. A number of legs are formed as an extension of the ribs and extend downward from the bearing surface and mutually distributed below the same. The short sides are similarly formed with fork lift pockets. The rib extension is formed with an inclination, so that the legs narrow in a direction away from the pallet underside.

DETAILED DESCRIPTION

[0023] FIG. 1 shows a pallet 100 in accordance with the disclosed embodiments viewed in perspective from above, whereas FIG. 2 shows the pallet in perspective from below. The pallet 100 comprises a first short side 101, a second opposite short side 102, a first long side 103 and a second opposite long side 104, so as to form a bearing/carrying surface for goods there between for transport or storage. The short sides and long sides are advantageously provided with a rounded lower edge (FIG. 4A) to simplify insertion of the forks of a hand pallet truck or fork lift. A number of legs 105 extend downward from the bearing surface, where compartments 111 between adjacent legs 105 of the respective short side 102 and 103 establish pockets for the forks of a hand pullet truck. Similar pockets 112 are formed between adjacent legs 105 of the respective long sides 103 and 105, so as to establish pockets for the forks of a fork lift.

[0024] Now with reference to FIG. 3, a section of the bearing surface is shown, consisting of a number of elongate ribs 106 and a number of transversal ribs 107 extending perpendicularly to the elongate ribs 106 and having their surface extending substantially perpendicularly when the pallet is resting upon a surface, thus forming the bearing surface of the pallet. A number of pairs of adjacent elongate leg ribs 106 constituted by a first and second elongate rib section 108, 109 in the area forming the leg 105, are arranged at a mutual angle in a direction, so that the ribs 108 and 109 are approaching each other in a direction away from the bearing surface of the pallet. The inclined elongate leg rib sections 108 and 109 with adjacent lateral rib sections 115 and 116 of two ribs 107 do in this way form a cavity 110 for accommodation of the leg 105 of another pallet stacked upon a first pallet. The angle of inclination of the elongate leg rib sections 108 and 109 is advantageously about 5 degrees with respect to the vertical. In an advantageous embodiment, half of the rib sections 108, 109, 115 and 116 forming the legs 105 exhibit a larger thickness than the remaining ribs 106, 107 and 109, and represents a reinforcing rib 108, but with minimal material consumption and minimal weight increase.

[0025] The framework of the pallet 100, which is cast in one piece, is illustrated in the form of a section in FIG. 5 having a frame in the form of the elongate ribs 106 and the transversal ribs 107. What is evident particularly from FIG. 5, the legs (not shown explicitly) are formed as an extension of four adjacent leg rib sections 108, 109, 115 and 116 of a respective elongate rib 106 and transversal rib 107, respectively, where each leg rib section 108, 109, 115 and 116 is formed with a break or step 113 a distance up from the underside of the pallet, so that the respective leg rib section is formed by an inclined lower part 106′ and a vertically extending upper part 106″. The transversal ribs are formed similarly (not shown). The surfaces marked X are virtual surfaces which are included to better illustrate the angle geometry of the framework. In FIG. 6 the virtual surfaces are removed to show a section of the framework of the pallet. FIGS. 4A and 4B are side views showing the angle geometry of the legs, formed as an extension of the ribs.

[0026] In order to utilize dead space between adjacent pallets with goods located upon a number of airplane pallets (not shown), the legs 105 are in a preferred embodiment closest to the long side and the short side of the pallets, respectively, arranged a distance away from the respective short side 101, 102 and long side 103, 104. This distance corresponds to the horizontal extension of the airplane pallet rail (not shown). In this way, pallets 100 placed in adjacent airplane pallets can with their respective bearing surfaces be arranged close to each other, and utilize dead space between adjacent load carrying airplane pallets in accordance with the prior art. The placement of these legs appears in particular from FIGS. 1, 2 and 4A.

[0027] Now with reference to FIG. 7, a partial section is shown, of two pallets stacked upon each other. This illustration shows an alternative advantageous embodiment of the transport pallets. In order to provide solid legs having good washability, some elongate ribs arranged tilted across the entire longitudinal direction. These elongate tilted ribs are illustrated by reference numeral 117. This solution maximize the external cross-section of the leg, eliminating step points in the leg and eliminating steps in the elongate rib. However, the transversal ribs 107 are vertical. This is necessary to obtain continuous partition lines and properly arranged release directions. The leg of the wall in this area therefore must have a step to secure mutual stacking. Since the legs are elongate in the longitudinal direction of the pallet, the steps are arranged so that they weaken the leg strength as little as possible, i.e. at the lateral ribs 107.

[0028] FIG. 8 shows release directions within regions of the pallet, shown as a section in perspective of two pallets stacked upon each other. The rib sections marked by reference numeral 188 have a release direction in an upward direction, whereas the rib sections marked by reference numeral 119 have a release direction in a downward direction. This embodiment of the pallet is constructed by taking a starting point in the inclined elongate ribs 117, and then the walls of the transversal ribs 107 are adjusted to obtain continuous partition lines.

[0029] Finally is should be mentioned that lower part of each side edge (not further illustrated) is inclined, having lower art of the side edge in a direction away from the pallet, to reduce risk of damage at contact with fork lift. This involves that the pallet is lifted instead of being pushed in if the lifting fork should be positioned at a level too high. Inclined side edge also contributes to increased bending stiffness of the pallet.

[0030] The pallet has several advantages. Except from the upper side of the ribs, the pallet does not have horizontal surfaces or compartments, a feature which will be highly valuated with respect to cleaning. The rigid framework results in a substantial bend-stiff pallet compared to prior art pallets. In addition, the rounded edge contributes to increased bending stiffness. The framework and arrangement having the legs distributed along the underside of the pallet provides good load distribution towards the surface, and the pallet will not kneel from high load. Last but not least, the material consumption is very low compared to prior art pallets. The pallet is capable of carrying higher weight with half of the material consumption compared to the prior art. The different heights of the elongate ribs and the transversal ribs, respectively, having shorter vertical extension, results in a maximal stiffness and also results in reduced weight and material consumption.

[0031] Locating the legs closest to the long sides and the short sides a distance away from the same, particularly for load of e.g. boxes upon an airplane pallet aboard the cargo compartment of a typical transport plane, results in that the cargo compartment is able to accommodate about 168 boxes compared to maximum 161 boxes in accordance with the prior art. An EPS carrier with salmon accommodates about 10 kg fish. This means 140 kg additional fish in an airplane transport.

[0032] It should also be emphasized that the size of the pallet and the shape of the legs are formed, so that 8 pallets can be arranged on a standard so-called PNC airplane fright pallet. In addition, the pallet is preferably formed of a two-component polymer, of which one plastic component serves as friction coating, cast within the pallet. The friction coatings of this type is normally applied to the external of pallets after casting of the pallet itself.
