Abstract

In the corners, walls (3) include web sections (13) designed to accept loading and impacts having components towards the principal plane and directed towards the pallet (1) corner. Resilient deflection takes place, the forces being and spread away and distributed into pallet regions behind the corner.

Description

I. Field of application

The invention relates to a pallet, as is usually the case to deposit on it and thus also to Transporting goods together with the pallet used and for example with the help of forklifts or forklift trucks are moved.

II. Technical background

Such pallets can be made from different Materials exist. In the case of transportation from products that are sensitive from a hygiene point of view such as fresh food, in particular Fresh meat, however, the problem is that for such products used a hygiene pallet Set of additional requirements in addition to the basic requirement of sufficient stability for exposure to the desired products must meet:

Firstly, this pallet must be made of one material exist, the upper surface of which is slightly contaminated, especially germs, can be cleaned, and in which such germs are extremely difficult can penetrate. Stand with regard to the choice of materials for this essentially metal, in particular Light metal, or plastic available, being made of Cost-based plastic, especially as an injection molding part made with a largely hollow, ribbed Interior, is used.

Another requirement is that such Pallets against mechanical loads like this must be resistant to having a drop test to a corner up to a certain height without Have to survive breakage and possibly a subsequent one Leakage test by inflating with overpressure.

So far, this requirement could only be met by be solved that the rib structure is so resilient worked that drop test with no damage or Survived destruction.

The disadvantage, however, was that it was for the sufficient elasticity of the rib structure is necessary was that this - opposite the main horizontal plane the pallet - at least vertical ribs on one side, i.e. the underside or the Top, not by an upper or lower End plate were firmly supported against each other.

Through this on at least the top or structure of such hygiene pallets open at the bottom became deep, sharp-edged and therefore difficult to clean Bags formed in which Contaminants and thus also germs could.

WO 94/10051 is a plastic pallet become known with a smooth topsoil, the one at the bottom with a ribbing is provided. This closed on all sides hollow bottom is with at its bottom welded feet under the a base plate is welded. The feet show intersecting in their hollow interior Ribs on the middle of the foot side surfaces support each other and therefore increase the load capacity of the feet.

III. Presentation of the invention a) Technical task

The object of the present invention is in creating a hygiene range, despite the continuous external surfaces and sufficient stability is so elastic that a corresponding drop test on a corner and subsequent Pressure test of the range can be passed and the pallet is still inexpensive and simple is to be produced. ,

b) solving the problem

This task is characterized by the Features of claims 1 and 8 solved. advantageous Embodiments result from the Dependent claims.

As a rule, the pallets in question are constructed so that the below the support member arranged feet, at the lower end by skid parts can be connected to individual runners, at least in the corner areas, possibly also in the Course of the outer edge of the pallet.

To survive a fold test on the corner. is the ribbing through web walls or in the corner area designed by corner web walls so that one in the corner area impact on the pallet in the direction the main level of the pallet takes place or at least Directional components of this main plane includes through the outer walls of the corner area to the further transfer inside corner web walls of the corner area is, these corner web walls and / or the Exterior walls are designed so that they at least some of the energy applied by elastic Absorb deformation, and possibly one distributing excessive part of the impact energy the one behind it viewed from the corner Derive areas. Because of a right angle Corner with the sector behind it deepens with increasing depth, there is already one drastic reduction in individual forces or force peaks.

Such an effect is, for example achieved in that the corner area, which is usually simultaneously represents the foot, one or more in the corner area arched corner web walls located relatively far out which has those adjacent to the corner Connect outer walls with each other and with yours External curvature inwards, i.e. towards the middle of the pallet, Clues.

There is also further from the corner inwards recessed corner web walls, also are arcuate, and are arranged that their outer curvature towards the corner, i.e. after outside, points. These inside corner web walls are based on regular ones, i.e. parallel to the Outer edges and web walls running in a rectangular grid, through which a corner chamber is formed in the corner area, in which the Corner web walls are located.

These inner and outer, each one or more, arcuate Corner web walls serve on the one hand to stabilize the adjacent walls, in particular the outer walls subject to the force, this corner chamber, on the other hand, however, at least one as the start and end point another, guided diagonally from the corner radially towards the center of the pallet Corner web wall, which also has a curved shape and that is precisely why as an elastic element, i.e. as a spring, between the arched corner web walls serves.

The corner web walls running radially inwards from the corner can either start at or on one of the outside, arc-shaped corner web walls the outside wall itself and they can be on one of the inside curved corner web walls end or on one of the regular, parallel to the Outer edge of the pallet-extending web walls, which the corner chamber limit.

In addition, one or both of the outer walls in the corner area, i.e. in the Area of the corner chamber, which otherwise run straight, at least one have hat-shaped or S-shaped twist, with hat-shaped twists should preferably be directed inwards. This also favors one Suspension of the outer wall towards your main level. The radial ones too Corner web walls can have such a twist.

Wall thicknesses, curvatures, transition radii and the like and materials, z. B. unreinforced polyethylene, are in tune with the desired elasticity and coordinate the desired ability to eliminate.

All web walls and / or corner web walls and / or outer walls are fixed, in particular in one piece, connected to one another, as is the case in the manufacture of a such ribbed part is common as a plastic injection molded part, or lie at least closely adjacent to the adjacent wall.

Despite the ribbing described, continuous, i.e. dense, Outer surfaces of the hygiene range in all spatial directions, i.e. also against that Interior of the tine pockets for the forklift tines, achieved in that the range of several individual parts with ribbed pockets that are open on one side is composed, each preferably made as a molded plastic part and by gluing or thermowelding when in use thermoplastic materials or other known methods tightly together be glued.

The individual parts can be viewed through openings or have open pockets on one side, if the individual parts are like this Be put together that the respective continuous outer surfaces of this Individual parts only represent the outer surfaces of the finished pallet.

• einem Mittelteil, welches einerseits einen über die gesamte Grundfläche der Palette durchgehenden Tragteil umfaßt sowie die vom Tragteil nach unten abragenden Füße, die sich insbesondere in den Eckbereichen befinden, und die in parallelen Richtungen an ihrem unteren Ende zu Kufenteilen verbunden sein können, sowie
• einer Deckelplatte, die in der Aufsicht ebenfalls der Grundfläche der Palette entspricht und auf das Tragteil als oberer Abschluß aufgesetzt wird, und weiterhin
• Kufenplatten, die den Grundflächen der Kufen entsprechen und auf deren Unterseite aufgesetzt werden.

Preferably, the pallet - viewed from the side and thus in the direction of the main plane - consists of

• a central part, which on the one hand comprises a support part which extends over the entire base area of the pallet, and the feet which project downwards from the support part and which are located in particular in the corner areas and which can be connected in parallel directions at their lower ends to skid parts, and
• a cover plate, which also corresponds to the base of the pallet in the supervision and is placed on the supporting part as the upper end, and further
• Skid plates that correspond to the base of the skids and are placed on the underside.

When fitting, ensure that there is a tight connection to prevent penetration of Prevent contamination and germs inside the pallet.

The middle part is on the underside of its support part as well as on all outer walls and surrounding walls with the exception of the top of the support member and the underside of the runner parts or the individual feet with a continuous dense outer surface provided so that by attaching the cover plate and the skid plates result in an overall tight, continuous exterior.

The cover plate and / or the skid plates point from their upper end plate (with the cover plate) or from the lower end plate (with the Skid plates) against the middle section pointing ribs, which with the Ribs in the middle section except for the exceptions described later match, so that when stacking and gluing or thermal Not only weld the outer walls, but also the individual ones Web walls that form the ribs are firmly connected to what the rigidity of the pallet increased significantly.

The above-described corner web walls are, however, particularly on their upper, possibly also or additionally at its lower end, partly not with the Cover plate or skid plate and their ribs connected, but end at a distance or in contact, but loosely, opposite this plate.

For this purpose, the cover plate itself cannot be in the area of the corner chamber have their own ribbing, and the corner web walls protrude above the upper edge of the rest of the middle section accordingly far upwards, so that it is directly on or end under the lower edge of the upper end plate of the cover plate. The same applies at the lower end of the corner web walls opposite the skid plates or if the individual feet are not connected to one another for runners for the end plates of the individual feet.

Likewise, the cover plate can also have ribs in the corner area, the total or only partially with those coming below Ribs of the corner areas of the middle section match. The rigidity in the Corner area can be controlled by the fact that some of the ribs in the Corner area between middle part and cover plate firmly connected become. If all ribs in the corner area with regard to their course must match, especially when thermal welding by a sufficient height separation of those web walls that are not together to be connected, the welding should be prevented.

As a result, the elasticity and spring action of the corner web walls is only in desired dimension through the flat end plates of the cover plate or Skid plate reduced.

Additionally or in addition to or instead of the one described above Mechanism is in the supporting part of the central part a predetermined bending point in an arc the corner area arranged to bend away one of the corner areas compared to the rest of the pallet and its elastic spring back favor.

The predetermined bending point consists of an arc-shaped bead, which in the Underside of the support part of the middle part is incorporated and in essentially from one to the other of those outer edges of the pallet stretches that strive from the corner in question. These too in cross section hat-shaped bead is formed as a continuous, dense outer surface and has no sharp inner corners or inner edges, which the cleaning of the External surfaces of the pallets can complicate, which of course also for all other inner edges of the pallets apply.

Run from the top of the middle section into the support section bead walls standing upright along the edges of the bead, and along the middle of which is an upstanding bead center wall. While the ribbed walls in turn firmly connected to the cover plate or its ribs the beading middle wall is only loosely on the underside of the upper end plate or the cover plate. Is actually a Bend the foot away from the rest of the pallet along the bead as Target bending point, so the bead center wall is pushed up and is thus supported on the upper end plate, which thereby leads to the outside at the top is deformed, and overall serves as a resilient element in this bend and causes an automatic return bend to the starting position.

An analogous training in the skid parts that separate the individual feet from each other connect and a bending of the corner area on the arranged there Hindrance to the foot is usually not necessary, since the foot parts are so little hard and stable that not here in addition, a predetermined bending point must be provided.

Another possibility is only in the cover plate and in the middle part those corner web walls that are to be welded together with one to arrange a matching course. A subsequent selection, e.g. B. by Milling in the vertical height extension, depending on which of the Corner web walls are to be welded together, and thus variations of Rigidity in the corner area is no longer possible.

Figures 1 show a variant of the pallet obliquely in the finished state from above or obliquely from below, while Figures 2 show the state before Represent connecting the individual parts.

The basic design and in particular the dimensions correspond to existing standards the known pallets.

As shown in FIGS. 2a and 2b, the pallet consists of a central part 21 the top of which a cover plate 8 is placed, and on its individual Skid parts 6 skid plates 9a and 9b are placed.

In the middle part 21 protrude from the plate-shaped upper support part 4, its size corresponds to the base of the pallet 1, down at every corner and in the One foot 5 each from the middle of each of the outer edges. In the longitudinal direction of the pallet are the three feet 5 together by a skid part 6 to a skid 7 connected, as best seen in Fig. 1 b.

As a result, each of the runners 7 has two in the space between the three feet 5 Tine pockets 25 for the tines z. B. a forklift so that the pallet in a known manner both in the longitudinal direction, that is between the runners 7, as well as in the transverse direction, through the aligned zinc pockets 25 of the individual runners 7 through, can be gripped by a forklift.

The outer plate of the cover plate 8 corresponds to the outer contour of the central part 21 and its upper end edge. The same applies to the skid plates 9a, 9b and the associated runner parts 6, so that after the precise fitting of Cover plate 8 or skid plates 9a, 9b a firm connection z. B. by thermal Welding those consisting of a thermoplastic, such as polyethylene Individual parts, is possible.

Because the individual parts match at least in their outer structure and thermal welding along the entire circumferential length, and in addition, if necessary, is also carried out along the internal ribs, continuous, dense outer surfaces of pallet 1 are created.

As best shown in FIG. 2, the skid plates 9a, 9b consist of flat Sheet material, without vertically rising edge areas or ribbing.

The cover plate 8, however, consists of an upper end plate 8 ', of which of outer walls 14a ', 14b' over the entire circumference of the end plate 8 'protrude downwards and also a large number of web walls in the interior 3 'or corner web walls 13', the ribbing and thus reinforcement serve the cover plate 8.

In addition, the cover plate 8, and thus its upper end plate 8 ' the upper side partially along the outer edges of edge elevations 22 prevent the goods placed on the pallet 1 from sliding down should, as well as partially in the central area, for example along the longitudinal and transverse central axes arranged, center elevations 23, which also slipping load placed on pallet 1 should oppose.

In order to be able to stack the pallets 1 empty one above the other, they are in the transverse direction arranged center elevations 23 arranged only over such an extent, that they are in the free spacing of the runners 7 of the pallet placed above 1 come to rest. The center elevations 23 arranged in the longitudinal direction on the other hand find in the central recesses 24 'of the middle runners 7 or above lying pallet 1 place. For this purpose, the middle lower skid plate 9b, which consists only of a lower end plate 9 ', corresponding center openings 24, the contour and positioning of the central recess 24 ' of the overlying middle skid part 6 of the middle part 21.

Fig. 3 shows a sectional view along the line III-III of Fig. 1a or 4c, that is in the longitudinal direction of the pallet along one of the outer runners 7.

It can be seen that at corresponding positions to the regular Web walls 3 of the middle part 21, which - as can be seen from the figures 2 - in Longitudinal direction and transverse direction, that is parallel to the outer edges 14a, 14b run, in the cover plate 8 the corresponding web walls 3 'on the same Position are arranged so that when connecting the intersecting Web walls 3 or 3 'existing ribs of these parts one above the other come and are thermally welded together. The same applies to the outer walls 14a, 14b and 14a ', 14b'.

The contact plane 10 'between the cover plate 8 and the middle part 21 is one horizontal plane, and thus runs parallel to the main plane 10 of the pallet 1.

Detailed designs of the palette in its corner areas are as follows with reference to Fig. 3 and a quarter of the middle part of the pallet Figures 4a and 4b and a bottom view of a Area representation described in Fig. 4c.

On the one hand, it can be seen from FIGS. 3, 4a, 4b that in the area of the feet 5 through the longitudinal and transverse web walls 3 in the middle part 21 upwards and continuously open at the bottom, chambers 19 are formed, while in the other areas - ie in the area of the support member 4 between the runners and in the area of the runners in the longitudinal sections in which the tine pockets 25 are present - the web walls 3 from the continuous outer surfaces only protrude on one side, up or down.

On the one hand, the ribbing in the corner area, in which usually one of the Feet 5 is arranged on the following design:

The arrangement of the corner web walls 13 within the corner chamber 19 'is best can be seen in the top view of the middle part from below according to FIG. 4c:

In each corner area is due to the 26 meeting in the outer corner Outer walls 14a, 14b on the one hand and essentially by contrast parallel, recessed regular web walls 3x and 3a on the other a corner chamber 19c is formed, in which corner web walls 13 are arranged, which have a different orientation than the usual web walls 3.

In the outer corner area of the corner chamber 19 'run at a distance from the outer corner and at a distance from each other arc-shaped, approximately quarter-circular corner web walls 13a, 13b in each case from one outer wall 14a to the other outer wall 14b, corner 26 being approximately the center of curvature of these corner web walls 13a, 13b forms, so this with its outer curvature inwards, against the center of the Pallet.

There is one in the diagonally opposite inner corner of the corner chamber 19c approximately mirror-inverted opposite curved, approximately quarter-circular Eckstegwand 13c arranged, which is analogous to one there Web wall 3a to the other, delimiting the corner chamber 19c, at a right angle to the web wall 3a, another web wall 3x runs.

Again, the inner corner formed by the web walls 3a and 3x forms the Corner chamber 19 'approximately the center of curvature of the corner web wall 13c, so that this is directed with its outer curvature against the corner 26 of the pallet 1.

In size, this corner web wall 13c corresponds approximately to the larger one, further inside lying the outer corner web walls 13b. The radius of the corner web walls 13b, 13c is approximately as large as the width, i.e. the smaller extent of the Corner chamber 19 '. These two arcuate corner web chambers 13b, 13c are by an approximately radial - with respect to the corner 26 of the pallet - extending Corner web wall 13d connected, which is not straight, but slightly curved is curved. While this corner web wall 13d approximately at a right angle to the External curvature of the corner web wall 13b hits, it goes into the outer circumference of the inside, arcuate corner web wall 13c gently over.

Another radially extending corner web wall 13e, which is also at right angles on the outer circumference of the quarter-circular corner web wall 13b, at a distance from radial corner web wall 13d, hits, goes smoothly into the web wall 3a, which at the same time represents an outer wall of the foot and thus the corner chamber 19 via.

In addition, the longer outer wall 14b of the corner chamber 19 'has a hat-shaped shape Bend 27, which is directed into the interior of the corner chamber 19 ', namely in Area between the point of impact of the largest outer arcuate Corner web walls 13b and that along the outer wall 14b from the corner 26 recessed corner of the corner chamber 19 '.

As shown in FIG. 3, the central part 21 has one over its entire extent constant height, and also all web walls 3 and corner web walls 13 and the outer walls 14 have the same height throughout.

Another possibility for the corner area is that - as in Fig. 4a, 4b can be seen - the corner web walls 13, which are arranged in the corner chambers 19 ', extend upward beyond the rest of the middle part 21. Thereby in this area in the cover plate 8 no ribbing is necessary.

Irrespective of this, not all corner web walls 13 or the corner web walls become 13 only partially at its upper and / or lower end with the cover plate 8 or the skid plate 9 firmly connected, in particular thermally welded.

In the exemplary embodiment according to FIG. 4c, only the quarter-circle-shaped ones lying inside are Corner web wall 13c and the largest of the outer quarter-circle Corner web walls 13b welded to the cover plate 8 by this analogously arranged and shaped corner web walls 13c ', 13b', as on best seen in Fig. 2b. In addition, there is also one of the arcuate corner web walls 13a corresponding corner web wall 13a 'is present in the cover plate 8, however, the corner web walls 13a and 13a 'are not welded together. During thermal welding of the entire cover plate 8 with the entire This is avoided in the middle part 21 by one of the corner web walls 13a and 13a 'in its height extension is shortened so that it touch level 10 'and so that the corresponding opposite corner web wall is not reached.

As FIG. 2b also shows, none of the corner web walls 13d, 13e corresponding corner web walls available. Instead, it's easy curved corner web walls 13 "in the corner chamber of the cover plate 8 transverse to its longitudinal extent, on both sides of the hat-shaped bend 27 'in the Outer edge, with opposing outer curvatures, from the Outer wall 14b 'to web wall 3a', which forms the corner chamber in the cover plate 8 limit opposite.

The aforementioned training makes it possible to act in or approximately in the main level Loads and blows against a corner 26 of the pallet 1 on the one hand cushion and on the other hand to areas on the inside of the pallet forward that besides an instantaneous deformation and recovery there is no permanent damage to the pallet.

Approximately the same effect is achieved by arranging a predetermined bending point a bead 12 in the underside of the support part 4 of the middle part 21 around the respective corner area, usually a foot 5, reached around.

The bead 12 is - as can be seen in Figures 4b and 4c - around an arc the corner 26 arranged around, each with a straight end piece towards the respective outer edge 14a, 14b. On the narrow side of the Pallet ends the bead 12 approximately in the middle of the distance between two runners 7. On the long side, the distance to the foot 5 is only about half as large.

The cross section of the bead 12 is an arc segment of less than 180 °, approximately 120-160 °.

Because of the increasing thickness of the supporting part 4 at the edges, the bead ends increasing thickness in this edge area, and thus does not immediately reach to the outermost edge 14a, 14b, since the depth of the bead 12 is less, about half as much is large, like the thickness of the support part 4 of the middle part 21, as best shown in FIG. 3 can be seen.

Viewed from the top of the middle part 21, the bead 12 acts as Bulge in the lower end plate of the supporting part, on which is vertical towering the web walls 3, which are perpendicular and parallel to the Cross the outer edges 14a, 14b of the pallet. These web walls 3 are missing above the bead 12. Instead, these web walls 3 go into bead web walls 17 over, which also along each of the edges of the bead 12 vertically upright and at the height of the other web walls 3, so towering extend to the contact plane 10 '.

Approximately at the same level, preferably in the area of the transition between the arcuate part and the straight longitudinal part of the Bead 12, the bead web walls 17 each have a section 18 with an S-shaped or hat-shaped curvature - viewed in the top view of FIG. 4c - on. At least on one of the bead web walls 17, as shown in FIG. B. in the such a section should lie outside the two bead web walls to be available.

In addition, a bead center wall 15 runs along the center line of the bead. This protrudes upwards beyond the contact plane 10 '.

The cover plate 8 has a ribbing projecting downwards, including the Beading web walls 17 ', and just as in the middle part 21 is in the area between the rib web walls 17 'no ribbing through the normal web walls 3 available. In addition, the cover part 8 lacks along the center of the bead extending middle wall, so that the bead center wall 15 of the middle part 21 to just below the end plate 8 'of the cover plate 8 ends.

If the corner area bends over the rest of the pallet due to excessive stress on the corner area, bending away (in Fig. 3: Bending away the right corner area down) defined along the Bead 12 take place. As a result, this is bulged further up, and the Beading center wall 15 presses against the end plate 8 'from below. their Stability through the own ribbing as well as the connection with the middle part is used as a resilient element to limit the bend and a to automatically return to the initial state.

The runner part 6 between the individual feet 5 is dimensioned relatively weak, and offers little resistance to such a bend.

As FIG. 4a shows, the bead center wall 15 runs without an S-shaped section or hat-shaped bend along the center line of the bead.
