Definitions
- the invention relates to a plastic pallet, which is composed of several parts.
- a plastic pallet comprises a deck for storing objects to be transported, as well as feet, which comprise first and second foot elements, the first foot elements being molded onto a lower side of the deck and the second foot elements onto runners which connect at least two feet to one another.
- the plastic pallet also includes connecting means for connecting first foot elements with corresponding second foot elements and thus the deck with the runners.
- the deck is essentially a plate-shaped body with a top and bottom of the deck.
- the top of the deck is generally flat, for example it can be made closed, but also as a lattice structure or as a combination of these.
- various functional elements can be molded onto the deck, such as, for example, recesses for receiving barrel-shaped containers, other positioning aids or limiters to prevent horizontal movement of goods on the pallet beyond the edge of the pallet.
- the underside of the deck can also be essentially flat, with the first foot elements being molded onto the underside of the deck. These stick out from the bottom of the deck and are made in one piece with the deck.
- four, six or nine first foot elements are formed on the underside of the deck, for example.
- the Ku fen, on which second foot elements are molded now connect at least two feet, with larger pallets also three or more feet with each other, each in a straight line one behind the other or as a lattice structure.
- the second foot elements are complementary to the first foot elements, ie they match them, for each first foot element there is a corresponding second foot element, depending on the position of the foot in the pallet - on one of the four Corners, on one of the four edges or inside, for example at the position of the geometric center of gravity of the top of the deck - the first and second foot elements and thus the feet can be shaped differently.
- the plastic pallet described here is a pallet that is composed of several parts, i.e. the runners with the second foot elements are connected to the deck on which the first foot elements are formed by means of connecting means. These connecting means do not necessarily have to connect all the first foot elements with corresponding second foot elements, but for example only be present in those first and second foot elements which correspond to the corners of the pallet.
- Pallets are used for the storage and transport of goods and are therefore exposed to a great deal of stress. Loaded pallets are often transported by forklift, which can easily damage the feet of the pallet. In addition, pallets are often transported on conveyor belts, which are often roller conveyors. Sometimes pallets also fall to the ground from a medium height, for example between heights of 1 m and 2 m, be it at the end of a conveyor belt after unloading or in the event of carelessness during transport from or to a truck, to name just one example. This can damage the pallet, particularly the feet and particularly the corner feet. Such damage often means that the pallets can no longer be used and must be replaced.
- a two-part pallet which consists of an upper part and a lower part.
- First foot elements are molded onto the underside of the top of the upper part
- the lower part comprises all runners in a lattice structure
- second foot elements are molded onto the runners, which are connected by the runners.
- the upper part and the lower part are connected to one another via the first and second foot elements, the connection can be designed as a plug-in connection, as an adhesive connection, as a hot-welding connection and / or as a latching connection.
- the object of the invention is therefore to develop a plastic pallet of the type described in such a way that the cost of replacement in the event of damage and repair of a pallet are reduced and more sustainable use is made possible.
- the connecting means are reversible and in at least a selected part of the feet each comprise a tab-shaped, preferably tongue-shaped, one of the two foot elements, and about a bending axis elastically flexible tab with a longitudinal axis perpendicular to the bending axis.
- They are reversible binding agents, i.e. the connection can be released and, if necessary, re-established.
- the tab can be molded onto either the first or the second foot elements. It is present in at least a selected part of the feet, for example this selected part can be formed by the feet which are positioned in the corners of the pallet or by the feet whose foot elements lie on the edge of runners. Basically, a tab can also be arranged in each of the feet.
- the tab is fixedly connected at a fixed end with respect to its longitudinal axis to the respective foot element, i.e. the first or second foot element, by being molded onto it, i.e. for example, in the injection molding process, simultaneously with the foot element, or subsequently installed.
- the other end of the tab with respect to its longitudinal axis is a free end.
- the tab is elastically flexible about a bending axis, it can, for example, be tongue-shaped, ie essentially based on the shape of a plate, with two large sides or large surfaces which are connected to one another via narrow sides or narrow surfaces, and the large sides having a much larger area than the narrow sides and the thickness - the distance between the large areas to each other - is much smaller than the width and length.
- the tongue shape also allows deviations from the strict geometry of a Plate too, for example variable thicknesses or narrow sides that do not run parallel to each other.
- the bending axis runs parallel to one of the narrow sides with which the tab is molded onto the corresponding first or second foot element.
- the distance between the two large sides must be dimensioned in such a way that an elastic bend perpendicular to the bending axis is possible, i.e. the surfaces of the large surfaces can be curved - by hand or with the help of a tool - so that the large sides are perpendicular in cross-section to the bending axis, i.e. along its longitudinal axis, can be bent elastic or concave or convex.
- the thicker the distance between the two large areas the more force must be applied to elastically deform the tab as described.
- the narrow side of the tongue-shaped tab with which it is molded onto the corresponding foot element the more stable the connection. But it is just if possible to make the narrow side with which the tab is formed on the first or second foot element so short that the tab can not only be bent elastically in the manner just described, but also perpendicular to it a second bending axis, which is perpendicular to the first bending axis and to the longitudinal axis of the tab.
- the tab can then have the shape of a column, for example.
- the lug even closer to the tongue shape, with a stronger base with which it is molded onto the first or second foot element and a shape tapering away from the base in one or both directions perpendicular to the longitudinal axis , so that it is flexible at least in an upper area closer to the free end about one or two bending axes.
- At least one hook is formed on the free end of the tab.
- the hook receptacle is complementary to the hook, i.e. to match its shape, so that a corresponding positive connection can be made.
- the form fit prevents the runners along the longitudinal axis of the tab, i.e. perpendicular to the top of the deck, can be removed from the deck.
- a positive connection in the other two directions is preferably produced in that the feet at least partially have a double-walled structure on their outer circumference exhibit.
- the first foot elements then protrude from the underside of the deck and so far from the runner that they are pushed into one another when assembled, which requires that one of the two foot elements has a smaller outer circumference than the other of the two foot elements has an inner circumference in order to accommodate one another to allow pushing.
- the double-walled structure on the one hand increases the stability against damage, for example by means of a forklift
- the training of a double-walled structure can also advantageously produce a non-positive connection from the deck to the runners along the normal to the top of the deck, i.e. parallel to the longitudinal axis of the flap.
- the outer circumference of the one foot element, which forms the inner part of the double-walled structure is formed with a slight excess compared to the inner diameter of the other foot element, which forms the outer part of the double-walled structure.
- the at least one hook and the hook receptacle are each arranged in the middle of the feet, namely in a top view and / or from the side, i.e. In the case of rectangular feet, the hook and hook receptacle are located approximately at the intersection of the diagonals of the rectangle in plan view and / or halfway between the top of the deck and a bottom of the runners. This provides a high level of protection against impact and impact from outside, for example with a fork-lift truck.
- connection via the hook can also be non-positive, the positive connection then taking place in directions that are parallel to the surface of the deck and perpendicular to the longitudinal axis of the flap.
- the hook is then additionally fixed by frictional forces, which can be achieved, for example, by dimensioning the length of the tab so that the hook rests in the hook receptacle without play or under tension.
- receptacle elements are formed on the hook which prevent the hook connection from coming loose.
- the closure elements thus replace or supplement the non-positive connection of the Hook with the hook receptacle and prevent movement of the hook from the hook receptacle in directions perpendicular to the longitudinal axis of the tab, that is in a plane parallel to the top of the deck.
- closure elements can, for example, be designed such that they also produce a positive connection of the hook with the hook receptacle in these directions in the plane parallel to the upper side of the deck, in addition to the positive connection in the direction of the longitudinal axis, which is the essential part of the deck to connect the runners.
- a hook guide element is advantageously formed on the hook receptacle, which when the feet are put together by moving the first and second foot elements along the longitudinal axis of the tab towards one another, the tab is elastic and continuously stronger Rest position is designed to deflect.
- the rest position of the flap is the position in which no bending forces act on the flap, that is to say it is generally oriented perpendicularly and parallel to the normal direction of the upper side of the deck.
- the hook and hook receptacle approach one another to move.
- the hook can, for example, constantly snap itself into the hook receptacle at the end of this process, but this snap-in can also be supported mechanically either manually or by a tool. If the parts of the pallet are assembled automatically in the course of production, the use of an appropriate tool is preferred. In this case, it is a snap hook connection that is releasable - that is reversible - in contrast to a latching connection, which is not releasable and only has one or more latching positions.
- the hook can be designed as a classic hook, ie as a curved end piece of the tab with an opening, the hook is then also formed perpendicular to the bending axis.
- this training perpendicular to the bending axis also limits the effectiveness of the hook, since the complementary hook receptacle must enable hooking.
- the hook engages behind a wall of the hook receptacle, but the tip of the hook must not engage too far behind this hook receptacle in order to enable the hook connection to be turned and released.
- the at least one hook is therefore designed as a widening of the tab along the bending axis and perpendicular to the longitudinal axis. This allows greater flexibility in the design of the hook, in particular the extent along the bending axis can also influence how strong the at least positive connection is: the longer the extension along the bending axis, the more the positive connection along the Normal direction of the top side resilient.
- the hook receptacle is expediently designed as a rail-shaped support perpendicular to the bending axis. On the top of the rail there is a support surface for the hook to match it.
- the support surface or the rail has a longitudinal direction of the rail which is perpendicular to the longitudinal axis of the bracket and to the bending axis.
- the tab With a corresponding design of the tab, it can be rotated about its longitudinal axis, so that the hook can be guided past the free end of the tab on the rail-shaped support during assembly. As soon as the end position is reached in which the two foot elements are assembled, the hook is automatically turned in the right direction due to the torsional tension. In order to facilitate this process and the handling of the hook, the free end of the tab can also be provided with a handle element.
- the rail-shaped support has a free end.
- the hook at the free end of the tab does not have to be rotated, but the bending of the tab is sufficient to guide the hook past the rail-shaped support into the end position.
- two hooks are formed on the free end of the tab on opposite sides along a direction parallel to the bending axis. Accordingly, there are also two hook receptacles that are separated by a space between. So it is a double hook and a Doppelha kenwork.
- the hooks can be connected by means of a grip element.
- the connection of the first and second foot elements and thus the individual parts of the pallet can be further strengthened in this way.
- the construction of the rail-shaped supports with a space in between can also suppress movement of the hook along the bending axis.
- the positive connection along the normal direction of the top of the deck is further strengthened. There are several ways to form locking elements on this hook receptacle if they are to be used.
- the closure elements include stop elements which are arranged on the free end of the rail-shaped supports on these and prevent the hook from being displaced beyond the free end.
- stop elements are simple surveys, for example in hemispherical or cuboid form.
- Corresponding stop elements can also be arranged on the rail-shaped supports in the direction of their fixed ends - the fixed ends mean those ends of the rail-shaped supports with which the rail-shaped supports on the corresponding foot element on which the hook receptacle is formed, and the distance between these stop elements on a rail can be dimensioned so that the hook fits exactly between them, so that the hook moves along the rail-shaped supports after reaching the end position is prevented.
- stop elements can also be formed at the free end of the rail-shaped support on the side thereof in the area of the leg and - protrude into the intermediate space during the formation of a double hook, thus tapering its opening.
- a hook guide element is formed there, which has a bevel for deflecting the tab from a rest position when assembling on a bottom of the hook receptacle that has the other foot element. If, for example, the hook receptacle is formed on the first foot element, the bevel is formed on the side of the hook receptacle that faces the second foot element. It is, for example, the underside of the rail-shaped support, the support surface forms the top of the rail-shaped support and the hook receptacle.
- the width of these slopes preferably corresponds to the width of the rail-shaped supports, so that the at least one hook is contacted by the slope in any case and the tab is deflected from its rest position.
- the slope should only include such an acute angle with the normal direction of the deck surface that does not prevent deflection, but the angle should not be so acute that the distance along the normal direction, over the length of which the deflection takes place, becomes too long, here there are natural limits to the height of your feet.
- an opening is formed on that of the two foot elements - that is to say on each corresponding foot element in the selected part of the foot elements - on which the hook receptacle is formed, through which the hook is accessible from outside the foot element.
- the hook receptacle is formed on the first foot element and the tab on the second foot element. An opening is then introduced into the deck so that the hook receptacle and the hook are easily accessible in the normal position of the pallet.

- the plastic pallet 1 also includes connecting means for the reversible connection of first foot elements 3 and corresponding second foot elements 4 and thus the deck 2 to the runners 6.
- the connecting means are present in at least one selected part of the feet, in the example shown there is the selected part of the feet from the corner feet 7 of the pallet, as in FIG. 5b, which shows a section through the plastic pallet 1 along the line BB shown in FIG. 5a perpendicular to the sheet plane.
- the runners 6 are designed here as real runners and not as a lattice structure, but this is also possible without further ado.
- the connecting means each comprise a tab 8 which is integrally formed on one of the two foot elements 3, 4 and which is elastically flexible about a bending axis K and has a longitudinal axis L perpendicular to the bending axis K.
- the bending axis K and the longitudinal axis L are marked in FIG. 2b
- FIG. 2a shows a plan view of the section of the exploded view from a plastic pallet 1 shown in FIG. 1
- FIG. 2b shows a section through the section along the line AA in FIG. 2a.
- Fig. 2c shows the section designated B in Fig. 2a in an enlarged view.
- the tab 8 can be seen in Fig. 1 and in Fig. 2b.
- the bending axis K is drawn in Fig. 2b and is perpendicular to the sheet plane.
- the longitudinal axis L lies in the leaf plane in FIG. 2b and in FIG. 2a it is perpendicular to it.
- the tab 8 is tongue-shaped or essentially plate-shaped.
- the tab 8 is connected at a fixed end with respect to the longitudinal axis L to the respective foot element - here the second foot element 4 or is formed thereon.
- At least one hook 9 is formed on the tab 8 at a free end with respect to its longitudinal axis L.
- two hooks 9 are formed as widenings of the tab 8 along the bending axis K and perpendicular to the longitudinal axis L. They are formed on opposite sides along a direction parallel to the bending axis K from.
- a grip element 10 on both sides of the free end of the tab 8 enables the tab 8 to be easily gripped with a tool or with the hands.
- the gripping surfaces 10 can be roughened for manual assembly.
- a hook recording 11 is shown for example in Fig. 2a and in the enlarged section in Fig. 2c with reference to the exploded view of Fig. 1.
- the hook receptacle 11 is designed as a rail-shaped support 12 perpendicular to the bending axis K.
- Rail-shaped means that the area on which the hook 9 rests on the rail-shaped support 12 is perpendicular to the longitudinal axis L and perpendicular to the bending axis K - that is, along the direction in which the tab 8 can be moved - has a greater longitudinal extent, than the hook 9 is wide.
- the two rail-shaped supports 12 in the example are firmly connected on two sides in the direction of view along the longitudinal axis L to the first foot element 3, which is molded onto the deck 2, that is to say they are molded onto it or formed thereon.
- the hook receptacle 11 is here designed as a rail-shaped support 12 perpendicular to the bending axis K and perpendicular to the longitudinal axis L, it has a free end 13, via which the hook 9 can be brought into the positive connection with the hook receptacle 11. Since two hooks 9 are formed in the example shown, two hook receptacles 11 are also correspondingly required, which are separated from one another by an intermediate space 14 which serves to introduce the tab 9 into the hook receptacle 11. In this way, the stability of the positive connection is increased.
- FIG. 3a-d show the first foot element 3 from different perspectives, without the second foot element 4.
- FIG. 3a shows a plan view
- FIG. 3b shows the hook receptacle 11 again enlarged and in detail in accordance with the detail B from FIG. 3a without it arranged second foot element 4 with tab 8.
- Fig. 3c shows a section through the first mitele element 3 along the line AA in Fig. 3a.
- 3d finally shows the first foot element 3 from below. 4 show similar views, but with assembled foot elements 3, 4.
- the top of the deck 2 has an opening 15 through which the hook 9 can be accessed from outside the first foot element 3 in the inserted state. This makes it easier to establish and release the connection. If the first foot element 3 and the second foot element 4 are put together, the feet formed from the two foot elements 3, 4 at least partially form a double-walled structure on their outer circumference. In the present case, the inner circumference of the first foot element 3 is smaller than the outer circumference of the second foot element 4, the latter is thus at least partially enclosed by the first foot element 3 during assembly. This increases the stability against damage and the stability when loaded from above.
- Closure elements are preferably formed on the hook receptacle 11, which prevent the connection between the first foot element 3 and the second foot element 4 from being inadvertently released.
- These closure elements can be formed in different ways.
- An example is shown in FIG. 3b, here the closure elements include stop elements 17, which are formed at the free end 13 of the rail-shaped supports 12 on their sides in the area where the tab 8 is in the connected state.
- the tab 8 can be pressed past the stop elements 17 into the intermediate space 14, the rounded edges serve for easier insertion.
- the tab 8 is at least in this area wider than the distance between the two stubble elements 17 in the sheet plane. The tab 8 can therefore only be introduced into the intermediate space 14 with a certain amount of force, which can be achieved by hand or with a tool.
- the closure elements comprise stop elements 18, which are arranged on the free end 13 of the rail-shaped supports 12 and prevent the hook 9 from being displaced beyond the free end 13 , as well as the stop elements 17 described above.
- Such stop elements 18 are shown in FIG. 7b, whereas FIG. 7a shows the stop elements 17 again.
- Fig. 7c shows a combination nation of the two types of stop elements 17 and 18.
- Fig. 8a-c show the sections CC, as they are marked in Fig. 7a-c.
- stop elements 17 engage the tab 8 and prevent their movement by engaging in the space in which the tabs 8 move, namely directly below the hook 9
- the stop elements 18 prevent the connection from being loosened, by preventing the grip element 10, on the underside of which the hooks 9 are formed, from sliding out of the intermediate space 14.
- stubble elements 18 can also be arranged on the other side of the grip element 10, so as to minimize the play of the tab 8 perpendicular to the bending axis K and perpendicular to the longitudinal axis L.
- a hook guide element 19 is formed on the hook receptacle 1 1, which has a slope 20 here or as a slope 20 for deflecting the tab 8 a rest position is formed during assembly, this can be clearly seen, for example, in FIG. 3c.
- it is arranged on an underside of the flake receptacle 1 1 that has the other foot element.
- the tab 8 is thereby when putting the feet together by moving the first and second foot elements 3, 4 along the longitudinal axis L of the tab 8 towards each other to elastic and continuously deflected from a rest position.
- the rest position of the tab 8 is shown, for example, in FIG. 2 b, the longitudinal axis L extends there parallel to the normal surface of the deck 2.
- FIG. 6 The effect of the hook guide element 19 with the slope 20 is shown in Fig. 6.
- the movement of the first foot element 3 and the second foot element 4 towards one another takes place along the bottom arrow pointing straight up.
- the tab 8 in the rest position moves initially only in this direction.
- the handle element 10 of the plate 8 meets the slope 20, the tab 8 is deflected elastically out of its rest position, the free end of the tab 8 on the handle element 10 follows the drawn arrow diagonally to the top left, while the two foot elements 3 , 4 continue to move towards each other in the previously displayed direction.
- the tab 8 or the hook 9 on the handle element 10 must be pressed with force over the stop elements - here stop elements 18 - this is symbolized by the uppermost, horizontal arrow . If this has taken place, the positive connection between the first foot element 3 and the second foot element 4 and thus between the deck 2 and the runners 6 is established.
- the entire pallet no longer has to be disposed of, but the runners 6 concerned can be detached from the deck 2 and replaced without great mechanical effort. Due to its design, the connection is released at least partially by a shock from a height of approx. 2m and more - which corresponds to typical situations in which pallets are damaged - so that the change effort is even lower. For the user of such a multi-part plastic pallet, this is more cost-effective than replacing the entire pallet with a new one. In addition, this concept also helps to reduce the amount of waste.
