Pallet for carrying a load
A pallet ( 100 ) comprises a platform section ( 101 ) and foot sections ( 103 - 107 ) protruding downwards from the platform section. The pallet comprises at least one elongated support element ( 108 ) between opposite edge areas of the pallet and going via a lower portion of a foot section ( 107 ) that is between and distances away from the opposite edge areas of the pallet. The elongated support element is connected to the opposite edge areas of the pallet with connections ( 109, 110 ) for receiving tensile stress acting on the elongated support element. The tensile stress of the elongated support element is increased in response to downwards arching bending of the platform section. Thus, the elongated support element tends to prevent the bending of the platform section.
1. A pallet comprising:
a platform section having an upper side for carrying load,
foot sections protruding downwards from the platform section, and
at least one elongated support element between opposite edge areas of the pallet and going via a lower portion of at least one first foot section that is between and distances away from the opposite edge areas of the pallet, the at least one first foot section belonging to the foot sections of the pallet,
wherein the elongated support element is connected to the opposite edge areas of the pallet with connections for receiving tensile stress acting on the elongated support element, and the tensile stress acting on the elongated support element is increased in response to downwards arching bending of the platform section, and
wherein the elongated support element is an elongated flexible element without load bearing stiffness against bending, and the elongated support element constitutes a closed loop and each of the connections for receiving the tensile stress has a part protruding through the closed loop, both branches of the closed loop between the connections going via the lower portion of the at least one first foot section.
2. A pallet according to claim 1 , wherein a cross-section of the elongated support element in terms of its area is less than 3% of area of a geometric surface delimited by a shortest closed geometric curve capable of surrounding the first foot section.
3. A pallet according to claim 2 , wherein a bottom surface of the first foot section comprises a groove for the elongated support element.
4. A pallet according to claim 3 , wherein a bottom surface of the first foot section comprises a recess forming a free room between the elongated support element and a bottom of the recess.
5. A pallet according to claim 2 , wherein a bottom surface of the first foot section comprises a recess forming a free room between the elongated support element and a bottom of the recess.
6. A pallet according to claim 1 , wherein a cross-section of the elongated support element in terms of its area is less than 2% of area of a base of a smallest volume geometric circular cylinder capable of including the first foot section.
7. A pallet according to claim 1 , wherein the elongated support element has a downwards convex profile between the connections for receiving the tensile stress acting on the elongated support element.
8. A pallet according to claim 7 , wherein a height difference between a lowest point of the elongated support element and the connections for receiving the tensile stress is at least 50% of a height of the pallet.
9. A pallet according to claim 1 , wherein there is a straight angle or a blunt and upwards opening angle between portions of the elongated support element on different sides of the lower portion of the first foot section.
10. A pallet according to claim 1 , wherein there is a blunt and upwards opening angle between portions of the elongated support element on different sides of the lower portion of the first foot section.
11. A pallet according to claim 1 , wherein a bottom surface of the first foot section comprises a groove for the elongated support element.
12. A pallet according to claim 1 , wherein a bottom surface of the first foot section comprises a recess forming a free room between the elongated support element and a bottom of the recess.
13. A pallet according to claim 1 , wherein the pallet comprises lower chords between lower portions of the foot sections and parallel with the platform section.
14. A pallet according to claim 13 , wherein bottom surfaces of the lower chords comprise grooves for the elongated support element.
15. A pallet according to claim 1 , wherein the elongated support element is an elongated flexible element without load bearing stiffness against bending.
16. A pallet according to claim 15 , wherein the elongated support element ( 108 ) is a flexible band.
17. A pallet according to claim 16 , wherein the flexible band is made of steel.
