Description

Transport pallet The invention relates to a pallet on which piece goods, for example packets, boxes, boards, building materials and others. piled up for transport will. This pallet should be designed so that the use of forklifts is possible.

Pallets of this type have hitherto been used preferably as wooden or metal pallets produced, on which corresponding foot parts or rollers are provided. It is also known to listen to such pallets in such a way that two wooden panels are connected by appropriate spacers so that between the Plates provide the space required to retract the forks of a forklift truck lst. All of these Paltten have a considerable weight, as they also are relatively expensive, they have to be transported back to the place of origin after use resulting in additional transport costs.

The object of the invention is to provide a pallet for transport purposes create that has a low weight and whose cost price is so low, that it can be destroyed as a one-way pallet after use. Such a palette consists according to the invention of siner from one any suitable Material made, the supporting surface forming corrugated sheet, preferably siner Corrugated sheet with an approximately trapezoidal wave or undulation profile1 on their as Underside serving side, with respect to the direction of the longitudinal axis of each Shafts rotated 90 a second from the same or another suitable Material existing corrugated sheet is attached.

Advantageously, for the upper plate serving as a support surface a plate with a relatively low onsulation height and a small undulation distance selected, while the corrugated sheet serving as a support on the floor has such an undulation height must have that the fork of a forklift is under the serving as a support surface upper corrugated sheet can be retracted. This can be used as a support on the floor serving plate into individual strips, each encompassing an undulation width are broken up at a suitable distance from each other on the top plate from below are attached forth. The distance between two such parts is then chosen so that that the central axis of the strip encompassing an undulation width in each case with the central axis of an arm of the forklift coincides, so that when loading or Unload the forklift with its two arms into the inside of this strip intervenes. With the correct choice of dimensions and strength ratios of the The material used is sufficient to give the pallet a certain maximum load capacity to provide only two such strips, which of course are symmetrical to Center axis of the pallet are arranged.

Un the pallet from all four sides with the fork of a forklift to be able to drive under, can in the individual waves of the lower plate, bsw, in din n individual strips encompassing the width of the undulation, in corresponding distance lateral openings can be provided through which the fork of the forklift is also vertical can be retracted to the direction of the longitudinal axis of the individual shafts. It is in this case, for example, it is also possible to use these individual strips as Manufacture individual pieces by a corresponding stamping or pressing process.

The material for such a pallet can either be appropriately corrugated Thin sheet metal or a plastic such as a synthetic resin, or are hard fiber, or a hard cardboard or plywood or

Sperrhols, or one made from a mixture of shredded fibers and a binder existing molding material can be used. Due to the special Shaping can keep the material thickness relatively low in all cases so that a substantial reduction in weight and price is achieved will. Particularly when using metal, the corrugated sheets can be made from very thin Sheets are pressed. On the other hand, there is another one even for hard cardboard sufficient strength.

Around the lower corrugated sheet, or the lower part of the pallet, For example, a strip encompassing an undulation width, with which the wing to connect the upper corrugated sheet, the individual parts depending on the material used be welded or glued together, or it can Riveted connections or metal chambers can be provided.

In the accompanying drawings are some exemplary embodiments for the invention, which will be briefly described in the following. In the Drawing shows Fig. 1 a transport pallet according to the invention in the direction of Seen arrow I of Fig. 2; Fig. 2 shows the same range through 90 ° rotated, d. H. seen in the direction of arrow II in Fig. 1, Fig. 3 another Embodiment of the pallet that is accessible to a forklift truck from all four sides is, seen in the direction of arrow III of FIG. 4, FIG. 4 the same pallet 90 ° rotated, cut along the line IV-IV in Fig. 3 and in the direction of the arrows seen, Fig. 5 on a scale reduced to about half the same range as seen in Figures 2 and 3 from above, with part of the upper corrugated sheet being cut out Fig. 6 is another embodiment for a pallet, from all four sides accessible for a forklift truck it, partly cut out according to the dash-dotted line Line VI-VI in Fig.

7, seen in the direction of the arrow; Fig. 7 the same pallet as in Fig. 6 rotated by 90 ° and partially cut along the dash-dotted line VII-VII in Fig. 6 seen in the filing direction.

In the embodiment of Fig. T and 2, the Tragfläehe is the Pallet formed by a corrugated sheet 1, which is a regular ondulation of trapezoidal profile. On the one facing the underside of the pallet Side of the corrugated sheet 1 is a corrugated sheet z attached so that the Längsaehsen Individual waves of this plate are at right angles to the axis alignment of the waves of the plate 1 run, this lower plate 2 has two waves facing downwards 2 ', 2 "ven trapezoidal profile, between which an upwardly directed wave greater undulation width is present, the spacing a of the longitudinal axes of these two shafts 2 ', 2 "is chosen because it corresponds to the distance between the central lobes of the two Arms of the fork of a Hmbstapler arises. the Broito b the waves 2 ', 2 "is dimensioned so that the arm of the fork of a forklift truck into the through the Shafts 2 'or 2 "limited, tubular cavity 3 of the shafts are retracted can. The same applies to the undulation height h of this plate, a selche Plate can, for example, be manufactured as a long strand in the width of the pallet and sawn off to the required length. It is different, too possible to produce a plate that covers several pallet widths next to each other, which results in an irregular undulation with two waves in the Distance a from each other, while in each case between two such pairs of waves only otwa a distance corresponding to the value of the width b is provided. This plate is then both in the longitudinal direction and in the transverse direction each cut to the dimensions corresponding to the dimensions of the plaette.

The undulation height H 'of the upper plate forming the traaflae is much less than the undulation height h of the lower plate. Also ilt, in the case of the upper plate 1, which, as said, t is perfectly regularly undulated, the Distance c between the longitudinal axes of two successive waves, or the width b ' of the individual waves, each significantly smaller than the corresponding value a or b with the lower plate 2. In this way, a perfect position of the stacked goods, In particular, goods lying next to one another with a relatively small contact surface, on the plate 1 serving as a support surface.

With this pallet described above, the fork of a forklift only be retracted on two opposite sides, while of the both other sides of the iOubstapler running at right angles to this the pallet cannot accommodate. This is generally undesirable. To one of pallet that can be picked up by the forklift truck on all four sides are in Further development of the invention in the waves serving as a support on the floor laterally Appropriate openings at a suitable distance for retracting the fork of the forklift intended. An example of this is shown on the basis of FIGS. 3, 4 and 5.

The plate 1 serving as a supporting surface is designed exactly as in the example described above according to FIGS. 1 and 2. Instead of a single, correspondingly corrugated plate 7 are in this example two each one undulation width comprising strips 12 'and 12 "perpendicular to the direction of undulation of the plate 1 attached to the underside, in such a way that the distance a between the longitudinal central axes of the two strips 12 'and 12 "the distance between the central axes of the fork arms of one Forklift truck. The strips 12 'and 12 "can, for example, be white be made that one with corresponding undulation height and undulation width manufactured panel with regular undulation of trapezoidal profile in suitable Sections parallel to the longitudinal axes of the individual waves in individual strips which each comprise an undulation width, as can be seen from FIG. 4 is.

The undulation height h of these strips 12 ', 12 "must be higher than the thickness of the fork arms of a forklift. In the strips 12 ', 12 "are laterally each approximately rectangular openings 13 are introduced, the height d of which is the thickness and whose width f corresponds to the width of the fork arms of a forklift truck. The distance a 'of the central axis of these openings 13 is equal to the distance between the central axes the fork arms of a forklift truck and corresponds to the distance a the Center axes of the strips 12 ', 12 ". The two strips 12', 12" are arranged so that the axes x of the openings 13 fall together in their extensions.

Di. Breakthroughs 13 can, for example, by punching in the Strips 12 ', 12 "be introduced.

In this way you get a pallet with the fork of a forklift eir @@ can be driven from all four sides, either in one of the two duzoh the double arrow m indicated directions into the tubular cavity 3, which is delimited by the two strips 12 'and 12 "or in one of the two by the double arrow n indicated directions through the one behind the other Openings 13 in the sate walls of the two disputes 12 'and 12 ".

Bringing the fork of the forklift into the interiors 3 of the strips 12 ', 12 "does not present any difficulties, since these openings are connected to the corresponding Each side are easily recognizable. However, since the stripes 12 ', 12 " viewed from the corresponding edges of the pallet, something towards the inside are offset towards the pallet, the points at which the fork retracts must be should be marked in a clearly recognizable manner. This can be, for example by a coat of paint at the points corresponding to the position of the openings 13 the outer sides of the flanges 15 and the edges of the plate 1 happen. It is also mögl @ ch, in the manner shown in FIGS. 3, 4 and 5, a recess 14 in each case to be provided at the relevant points in the support plate 1 or the flange 15. Finally, for example, a cover piece can also be placed above the openings 13 the undulating edge of the plate 1 should be attached so that the profile is covered is and in this way a deficiency arises.

In Fig. 5 is on a reduced, about half the scale, the pallet sideways in plan view. Part of the corrugated sheet 1 forming the wing has been removed, so @@@ you can see the stripe 12 'ven above. The openings 13 and the notches 14 to identify the position of the openings 13 can be seen in FIG. the The representation is purely schematic and no openings are made 13 to indicate the material thickness of the strips 12 ′, 12 ″, which becomes visible at the top.

In the embodiment according to FIGS. 3 to 5, the openings were 13 for introducing the fork of the forklift perpendicular to the axial direction of the individual Shafts 12 ', 12 "of the part intended to be placed on the floor in the same Waves introduced themselves. Of course there is also the possibility to go through corresponding special shape of the upper corrugated sheet forming the wing the openings for the introduction of the fork from one direction through a corresponding one Design the waves to achieve this plate while in the perpendicular direction for this, as with the examples described above, the ones to be placed on the floor certain parts are drawn in. A selehe solution requires that the appropriate one Place a wave of greater waviness width, corresponding to the width of one Fork arm, is provided in the upper corrugated sheet. Since in this case the upper one Plate alone has to bear the load, so must, in particular, those during use ven molding materials, the panel thickness must be greater at this part of the omdulation width than the rest of the flatten. With an ontspreshenden consideration of the The height required to accommodate the fork armMC will, however, in this case be the pallet Relatively high To keep this part out, comb the below the as a wing this Eberen Flatte amsusetesnden Stripes, instead of cutting them out of a correspondingly shaped plate, as individual pieces Produce a good shape. An example of such a palette is in the Figures 6 and 7 shown.

In Fig. 6, the right-most part of the pallet is in section shown in accordance with the dash-dotted line VI-VI in Fig. 7, in the direction the arrows go while in Fig. 7, the part shown on the right of the pallet in Section along the dash-dotted line VII-VII in FIG. 6, also in the direction of the arrow seen is shown.

The upper plate 21 is provided with two shafts 24 of greater undulation width versohen whose central axes have a distance a 'from each other, the distance corresponds to the fork arms of a forklift. The undulation heights of this upper one However, plate 21 is smaller than the thickness of the fork arms.

Transverse to the direction of undulation of the plate 21 are on its underside the two strips 22 'and 22 "are attached, each of which is roughly a wave in a appropriately sized corrugated sheet would correspond. In each case on the shaft greater undulation width 24 of the plate 21 corresponding Stells is on dan walls a corresponding recess is provided for parts 22 ′ and 22 ″, and flange 25 of the two strips 22 'and 22 "over that of the undulation width of the shaft 24 corresponding Offset length down so that it forms a trough-shaped part 26, which together encloses a tubular space 23 with the wool 24. The dimensions of this Space 23 in height and width are chosen so that the fork ekines forklift in in space 23, or in the coaxially one behind the other, dueh the shaft 24 and the trough-shaped parts 26 formed openings biv.

Spaces can be introduced. On the other hand is the andulation height h of the two strips 22 ', 22 "are sufficient to also pass through these two parts formed, tubular spaces 27 to retract the fork of a forklift truck.

Nit consideration of the goods to be stacked on the pallet and its perfect location on the pallet, it is, as already mentioned, desirable for the upper corrugated sheet 1 or 21 is not too large a. To provide undulation width e, whereby the undulation height of this corrugated sheet is limited in a certain sense. Of course, it can be used as a corrugated sheet that can be placed on the floor a corrugated sheet can also be used, which has several undulation widths. However, it is necessary to dimension this corrugated sheet or its undulation so that that the retraction of the fork of a forklift is possible. One chooses that Dimensions most favorable so that each fork arm in the one already shown in FIG Way straight into the tubular cavity created by a shaft of the unteron plate is enclosed, can be introduced. this results for the lower plate generally a greater undulation height than for the obare plate and it can in this? all be advantageous in the manner previously described the lower plate either to be limited to only two waves, or to individual ones, to only one To replace strips comprising undulation width, as shown in FIG. 4 is. With regard to the required stability, these, based on the upper plate, as it were serving as transverse ribs waves or

Strips are correspondingly high and have a greater material thickness than the top plate.

It goes without saying that these are the ones described above Plaetten only to embodiments of the invention that have a different application of the inventive concept do not exclude.

As already mentioned above, either Metal in the form of appropriately pressed Bloch or light metal injection gufl in question. Instead, however, it can also be, for example, in a strand or in forms Pressed plastics or a pressed material made from a mixture of non-climbing Reduced fiber stiffeners such as wood and a binder can be used. In the end are also corrugated sheets made of plywood or laminated wood or hardboard or hardboard corrugated sheets suitable for the production of such pallets.

Even if these pallets are not used as one-way pallets for subsequent use Destruction is determined by the result of the static properties The reduction in material thickness caused by the corrugated sheets saves a considerable amount of weight and achieved a reduction in production costs.

As already said above, the individual parts can also be riveted, such as tubular rivets, or can be connected to one another by staples. This can be, for example only at the place of use and shortly before commissioning, with the help of a corresponding Riveting or Klanmervorrichtung take place, whereby namely bii made of cardboard or a One-way pallets made up of plastic an extremely space-saving shipping and storage space is available.

Finally, it should be noted that the drawings for the the embodiments described above are purely schematic and in none Way can be considered to be true to scale in their properties.
