Definitions

  • the invention relates to a transport pallet made from plastic material according to the preamble of patent claim one.
  • Transport pallets made from plastic material are generally used for transporting stackable goods and similar.
  • the transport pallets can be provided in different sizes wherein however the dimensions for so-called euro pallets are predetermined due to standardization. This is provided for reasons of simplifying transportation so that transport pallets from different vendors are compatible without any problems with other pallets.
  • Transport pallets made from plastic material are typically provided in two components and include a cover plate which forms the actual support surface for goods to be received and a base element which forms a standing surface for the transport pallet.
  • the cover plate and the base element are connected with one another by plural support elements over a circumference but also in center portions of the pallet wherein the support elements are either configured separately and/or configured at the cover plate or at the base element.
  • the cover plate and the base bar are permanently connected with the support elements through welding or gluing.
  • the cover plate is firmly interlocked with the base bar through snap locking elements (DE 10 2006 027 451 A1) in order to provide an interconnection between the cover plate and the base element for forming the transport pallet.
  • Interlocking connections of this type which are typically formed from plural engagement lugs and complementary engagement recess have a certain amount of flexibility due to tolerances which to a certain extent helps to avoid damaging the pallet in the portion of the support bases with respect to lateral collision forces as they can occur for example when the pallet is handled with a forklift.
  • the engagement lugs can tear under excessive loads which can lead to a destruction of the support elements which in the simplest case requires a the reinstallation of the support base but which can also lead to damages of the engagement members configured with the support lugs, so that complex repair work is required.
  • the pallets are circumferentially provided with a respective openings for engagement of the forklift tongs or other engagement elements, wherein typically the adjacent support elements form the engagement openings for the forklift tongues and similar between one another.
  • lifting carts are used for transporting the pallets wherein these lifting carts can also be forklifts which, however, are provided with an additional elevation adjustable mast lifting element.
  • These lifting carts include a wheel arm lifting element in a lower portion which wheel arm lifting element is separate from the mast lifting element arranged there above. These lifting carts improve stacking work and facilitate for example removing half pallets from euro pallets. Lifting carts of this type with separate wheel arm lift and mast lift are produced for example by the Jungheinrich Company, however they are also available from other vendors.
  • the support bases are configured sleeve shaped and by using an engagement element that is advantageously glued together with the cover plate and arranged at an upper end of the support base which upper end is oriented towards the cover plate of the pallet wherein the engagement element engages respective engagement recesses at the inner wall of the sleeve shaped support base with laterally extending engagement lugs.
  • the engagement element can disengage from the support bases, so that a new support base can be inserted as required.
  • the interlocking can be levered out when large forces occur, for example when incorrect handling is performed by a forklift, so that the interlocking is disengaged.
  • pallets configured from individual components to use bayonet bolts as connection members, thus for example for attaching replaceable supports skids at support bases according to DE 10 2008 047 856A1.
  • the cover plate is connected with the base element by separate closure elements, in particular closure bolts wherein each closure element is advantageously arranged in a support element and provided with a rated breaking point that is configured as a tension element.
  • closure elements in particular closure bolts
  • each closure element is advantageously arranged in a support element and provided with a rated breaking point that is configured as a tension element.
  • each closure element is configured as a tension element which firmly connects the cover plate and the base element with one another through tensioning.
  • the closure element is configured as a bayonet closure element according to claim 4 which yields a simple attachment of the pallet elements and only the bayonet bolts need to be inserted into the respective receivers and rotated, so that the cover plate and the base plate are clamped together so that a stable interconnection of the pallet is achieved.
  • each of the support elements which hold the base plate and the cover plate at a distance from one another and connects them with one another is configured with at least one closure element.
  • closure element can also be configured as a bolt with a screw thread which is insertable into a respective screw thread opening at the base plate or the base bar.
  • closure bolts are inserted from below, this means from a bottom side of the base bar in upward direction.
  • the bolt is formed here with an expansion so that a bolt section is formed that has a larger diameter than the bolt diameter, wherein the bayonet closure or the screw closure is provided at the opposite bolt end. This yields a respective stop when actuating the bayonet closure or the screw thread in order to provide a clamping effect between the elements in order to form the pallet.
  • closure elements are made from plastic material, thus advantageously bolt shaped, wherein the bolts in turn are advantageously configured hollow.
  • the rated breakpoint can be for example formed in a simple manner through a circumferential groove, in particular a V-shaped notch.
  • the depth of the groove and the material weakening of the closure element caused thereby or of the wall thickness of the closure element advantageously configured as a hollow bolt allows to predetermine the sensibility of the rated breakpoint with simple measures, this means it can be determined above which introduced force the rated breaking of the closure element occurs.
  • forming the rated breakpoint as a groove or notch is not mandatory, rather the rated breakpoint can also be configured differently, thus in that openings or similar perforations or material weakening's are provided over the circumference.
  • the expanded bolt section includes an inner wall and an outer wall which define an annular cavity between one another, wherein offset ribs within radial bars are provided within the annular cavity, wherein the ribs connect the inner wall with the outer wall and form respective stop surfaces for engagement of the rotating tool for rotating the bolt in order to provide the preload.

  • numeral 1 designates the cover plate which forms the support surface 2 of the transport pallet with its upper main surface.
  • the base element 3 of the pallet which is formed herein by skids 4 that extend in parallel and perpendicular to one another, wherein the skids form the contact surfaces for the base element 3 .
  • the upper cover plate 1 and the base element 3 arranged thereunder are arranged at a distance from one another thus through support elements 5 which can be provided in different configurations.
  • the support elements 5 are formed by support element sections 5 a integrally molded at a bottom side of the cover plate 1 , protruding in downward direction and circumferentially configured, through upward oriented support element sections 5 b integrally molded at the topside of the base element 3 , wherein the support element sections 5 b are also circumferentially configured, and by a support sleeve 5 c placed there above one an outside.
  • the lower support element section 5 b includes an inner wall 6 and an outer wall 7 that are offset from one another and in an assembled condition the sleeve 5 c contacts the outer wall 7 .
  • the support element section 5 a integrally molded at the upper cover plate 1 contacts the inner wall 6 and the upper face 8 of the sleeve 5 and contacts an upper shoulder 9 of the cover plate 1 so that a stable support interconnection is provided.
  • FIG. 1 also illustrates a closure element 11 which is formed herein by a bolt 12 which has an annular expansion at its lower free end and a bolt section 13 with a larger diameter than the bolt 12 .
  • a bayonet closure element 14 which is formed herein by two opposite screw thread sections 15 that extend over a partial circumference of the bolt and protrude in an outward direction, wherein, however, only one screw thread section 15 is illustrated in FIG. 1 .
  • the non-illustrated screw thread section is exactly on the opposite side of the closure bolt which is not visible in this figure illustration.
  • FIG. 2 illustrates the bolt shaped closure element 11 in assembled condition.
  • the bolt 12 is inserted from a bottom side of the base element 3 into the support base through which it reaches completely which, however, is not mandatory.
  • the bolt according to FIG. 2 is inserted into a sleeve 17 formed in an interior of the support element section 5 b which sleeve is connected according to FIG. 2 through a radial bars 18 with the inner wall 6 of the support element section 5 b .
  • the bolt extends through the sleeve 5 c in upward direction into a sleeve shaped receiving opening 19 of the upper cover plate or of the support element section 5 a , wherein the opening is also evident at the support surface 2 of the cover plate 1 in FIG. 1 .
  • Shoulders 21 that are complementary to the bayonet closure element 11 are provided in the opening 19 , wherein the shoulders only extend over a partial circumference of the opening 19 and form the actual bayonet closure together with the bayonet closure element 11 or the two screw thread sections 15 described herein.
  • the bayonet closure element 14 Since the screw sections 15 of the bayonet closure element 14 and also the opposite shoulders 21 interacting therewith are arranged at such distance from one another so that the bolt with the bayonet closure element 14 can be run through, the bayonet closure element only has to be the rotated after inserting the closure bolt 12 , so that the bayonet surfaces are preloaded relative to one another.
  • the bolt section 13 configured at a head of the closure bolt 12 furthermore contacts an opposite shoulder 23 in an opening 24 of the base element 3 a corresponding preload is achieved with increasing rotation of the bolt 12 so that a firm interconnection of the upper cover plate 1 with the lower base element 3 is provided.
  • the hollow configured bolt 12 is configured with a rated breakpoint 25 that can be configured in a suitable manner, thus through a V-shaped groove shaped circumferential notch.
  • the braking force is predetermined at the rated breakpoint so that a respective setting is feasible beyond which force between cover plate and base element the predetermined rated fracture occurs.
  • the rated breakpoint is advantageously configured at an upper end of the bolt 12 , in particular at the cover plate or slightly below the bayonet element 15 .
  • each support element 5 includes at least one receiver for a bolt shaped closure element 11 .
  • two receivers can be provided as illustrated in FIG. 1 for the corner side support element 5 .
  • the bolt 12 instead of being provided with a bayonet closure at its upper end, is provided with a screw thread and can be screwed into a respective through screw thread opening of the cover plate 1 . Also this preloads the cover plate 1 and the base element 3 relative to one another. When there is an excessive load and a fracture of a bolt at the rated breakpoint provided for this purpose the bolt can be unthreaded and the interconnection of the pallet can be provided through another screw bolt.
  • the expanded bolt section 13 as apparent from FIGS. 2 and 3 is provided with an inner wall and an outer wall which form an annular cavity 27 between one another.
  • radial bars can be arranged at a distance from one another, thus in particular formed as ribs which extend from an inner wall to an outer wall and can be used as a contact surface for a suitable turning tool, so that the bolt can be threaded in or threaded out with a tool.

  • the locking bars and the teething are thus configured so that rotating the closure element 11 into the closed position in order to lock the cover plate with the base element or the base bar advantageously automatically provides a locking acting against the closing movement due to the engagement of the locking bars 33 in the teething 34 .
  • closing the bayonet bolt provides the interlocking between the cover plate and the base element or the base bar 3 ; however the bayonet closure is blocked in a reverse direction and cannot be disengage independently any more.
  • locking bars 33 are provided for this purpose with a slanted flank 36 and the teething 34 includes a locking shoulder 37 distributed over the circumference and advantageously oriented radially inward, wherein an additional slanted surface 38 adjoins the locking shoulder 37 .
  • the slanted surface 36 of the locking bar moves over the slanted surface 38 of the teething, whereas an opening of the bayonet closure is prevented in opposite direction in that the bar surface at each bar 33 comes in contact with a locking shoulder 37 of the teething 34 and thus a rotation in unlocking direction for opening the bayonet closure is blocked and prevented.
  • other embodiments are certainly feasible.
  • one locking bar would already suffice, however plural locking bars distributed over the circumference, in particular four locking bars like in the illustrated embodiment are useful.
