Definitions
- the invention relates to a charge carrier with a base body made from a particle foam according to the preamble of claim 1 .
- Such load carriers are regularly used for the transport of piece goods.
- the base body made of particle foam is very soft, so that sensitive piece goods such as components for the automotive industry are not damaged if they come into contact with the base body.
- the load carriers are equipped with functional elements made of a material that is harder than the particle foam.
- retaining rails for the piece goods are used as functional elements, which hold the piece goods in position and prevent them from slipping.
- Such functional elements have to be fixed to the base body, with adhesive or other additional fastening means such as screws usually being used. This is often felt to be cumbersome. It is therefore the object of the invention to develop a charge carrier of the type mentioned at the outset in such a way that it can be manufactured more easily.
- a charge carrier having the features of claim 1 .
- Advantageous developments of the invention are the subject matter of the dependent claims.
- the invention is based on the idea of simplifying the attachment of the at least one functional element to the base body in that it is not fixed with additional attachment means such as adhesive or screws, but is anchored in the base body in a quasi-positive manner.
- the functional element is inserted with its anchoring section into the depression assigned to it, with the holding ribs being inserted into the receiving grooves forming an undercut of the depression.
- the insertion can be carried out with little effort while the functional element is firmly fixed in the base body after it has cooled down.
- the base body which is still soft, can be at least partially elastically deformed in the area of the depression assigned to the functional element when the functional element is inserted with its anchoring part into the depression.
- the functional element can have a width in the area of its anchoring part that is slightly larger, for example by about 2%, than the width of the recess would be if no functional element were inserted into it.
- the base body then rests at least in sections on the anchoring part in a positive and non-positive manner and holds the functional element in place.
- Each anchoring section expediently has an engagement section which is accommodated in the associated recess and from which the retaining ribs protrude on opposite sides. It is preferred that the holding ribs each protrude by at least 1.5 mm, preferably by at least 2 mm, from the respective engagement part.
- the receiving grooves must also be of a suitable depth to accommodate the retaining ribs so that there is a stable connection. Furthermore, it is preferred that the boundary surfaces of each indentation bear against the engagement part of the functional element associated with the indentation, so that it is even more difficult to pull the holding ribs out of the receiving grooves.
- each well through the functional element assigned to it can be stretched with deformation of the base body, so that there is an additional frictional connection between the base body and the respective functional element.
- the at least one functional element can be dimensioned in such a way that its engagement part and its retaining ribs are inserted with a precise fit into the associated depression and the receiving grooves of a base body that has been removed from the sintering mold and has not yet cooled, and that the deformation of the base body increases due to its volume reduction during cooling ambient temperature results.
- each anchoring part has a notch facing one of the boundary surfaces, into which a projection protruding from the relevant boundary surface engages.
- the projection can have a smaller length than the indentation, so that there is some play.
- the at least one functional element is expediently made of hard plastic. It is also advantageously formed in one piece, preferably as an injection molded part. Such parts are easy to manufacture and have a high level of stability.
- the at least one functional element is a holding bar with a holding part for piece goods. But it can also fulfill other functions.
- the receiving grooves are symmetrically opposite one another with respect to a median longitudinal plane of the recess from which they extend, possibly with the exception of the area in which the notch is arranged.
- the depth of each of the receiving grooves, measured from the respective boundary surface increases continuously up to a maximum depth. This makes it easier to insert the respective functional element into the associated depression.
- FIG. 1b detailed representations of the load carrier according to FIG. 1b in a perspective view and in section;
- Fig. 3a, b a holding strip in a perspective view and in side view and
- FIG. 4 shows a detailed representation of the charge carrier according to FIG. 1a in section.
- the load carrier 10 shown in the drawing is used to store and transport components for the automotive industry. It has a one-piece base body 12 made of a particle foam, which has a base 14 and walls 16 that stand up from the base 14 and border a receiving space 18 that is open at the top for the components. Two functional elements in the form of holding strips 20 are fixed to the floor 14, each of which has a holding part 22 with upstanding teeth 24, between which the components can be inserted.
- the holding strips 20 are identical in construction as injection-moulded parts made in one piece from a hard plastic.
- Each retaining strip 20 is assigned a depression 26 in the base 14 of the base body, into which an anchoring part 28 of the retaining strip 20 engages.
- the anchoring portion 28 has an engaging portion 30 received in the depression and retaining ribs 32 projecting from the engaging portion 30 in opposite directions by about 2 mm.
- One of the retaining ribs 32 extends over the entire length of the retaining strip 20, while the other retaining rib 32 is interrupted in the middle of the retaining strip 20 by a notch 34.
- Extending from each of the depressions 26 in two boundary surfaces 36 facing one another is a receiving channel 38, which is bounded on three sides by the base body 12 and is open towards the depression 26, and the depth of which initially increases continuously from the respective boundary surface 36 until it reached a maximum depth.
- Approximately in the middle of the recesses 26 is from one of the boundary surfaces 36 before a projection 40 in the Notch 34 of the holding bar 20 in question engages.
- the projection 40 is measured in the longitudinal direction of the holding strip 20 shorter than the notch 34 so that it is accommodated in this with play.
- the base body 12 is first produced in a sintering process by the application of heat in a sintering mold. Before it cools down to ambient temperature, the base body 12 is removed from the sintering mold and the retaining strips 20 are inserted into the depressions 26, with the particle foam material, which is still soft, being slightly elastically deformed. When it cools down to ambient temperature, it contracts so that on the one hand the boundary surfaces 36 rest against the engagement parts 30 and on the other hand the base body 12 is under tension or stretched in the area of the depressions 26 . This is achieved in that the width X (see. Fig. 3b) of the engagement part 30 is 1% to 3% and preferably 2% greater than the distance A (see. Fig.
- the width Y of the retaining bar 20 measured in the area of the retaining ribs 32 can be 1% to 3% and preferably 2% greater than the width B that the depression 26 would have in the area of the receiving grooves 38 if there were no retaining bar in it 20 would be used.
- the invention relates to a charge carrier 10 with a base body 12 made of a particle foam, in particular made of expanded polypropylene (EPP) or expanded polyurethane (EPU), and with at least one functional element 20, which consists of a material that is harder than the particle foam.
- the base body 12 has a recess 26 assigned to each functional element 20, from which a receiving channel 38, which is bounded on three sides by the base body 12 and is open to the recess 26, extends in two mutually facing boundary surfaces 36, and that each Functional element 20 has a projecting into its associated recess 26 anchoring portion 28 which holding ribs 32 which protrude away from one another and engage in each case in one of the receiving grooves.
