Description

Packaging for piece goods

The invention relates to a packaging for piece goods such as Furniture, machines, devices such as televisions and the like with one over the corner areas Part of the edges and surface parts of the piece to be packaged gripping upholstery elements.

It is known, for example, sensitive items for packing piece goods Devices to use upholstery elements, each over the corner area of the to be packed Piece (see U.S. Patents 3,166,227, 3 B4 798, 3,580,469 and 3,946 874).

It is also known to have such cushion elements in the form of panels or to provide clamps that grip the item to be packaged (see US Pat 3 404 826, 3 564 811 and 3 845 650).

It is also known, especially smaller pieces to be packaged to be surrounded with housing-like upholstery elements (cf.

U.S. Patent 3,181,766). The well-known upholstery elements are made of wood or wood products, but preferably made of flexible materials, e.g. corrugated cardboard or made of plastics that are thermoplastically molded, foamed or foamed. The known only across the corner areas of each piece to be packaged reaching Upholstery elements have the disadvantage that they offer very limited protection against damage of the item to be packaged and therefore actually only in connection with more or less solid outer packaging can be used, for example with wooden boxes or corrugated cardboard boxes. The plate-shaped upholstery elements are very largely modeled after the piece to be packaged and therefore leave none universal, i.e. system-like use. This restriction is even more pronounced for those well-known upholstery elements that have a housing-like shape for the piece to be packaged take up.

In contrast, the invention is based on the object of a simple universally usable basic parts to look at the simple packaging and universally usable upholstery elements securely attached to the item to be packaged and can be kept there safely until an outer packaging cover is appropriate. The basic parts of the packaging should match the item to be packed already so much protection That also offer a cheap outer shell is sufficient that actually only the packaging parts around the item to be packed holding around together. On the other hand, they should be attached around the piece to be packaged Packaging parts also take up little space, so that still a safe one convenient insertion into a more or less rigid outer packaging sleeve, for example a wooden box or a folding box or a corrugated cardboard box is possible.

This object is achieved according to the invention in that for the Packaging apart from the upholstery elements varies from upholstery element to upholstery element profile strips extending around the piece to be packaged are provided which with their ends in corresponding receptacles formed on the upholstery elements are to be plugged in. As a result, the upholstery elements form together with these profile strips an effective packaging frame system that already has so much holding strength when it is put on on a piece to be packed, that with this packaging frame system occupied piece easily and safely further packaging operations, for example Shrinking in a plastic sleeve, without any Protective parts of the packaging move out of their position or move at all could fall off.

The profile strips can in a preferred embodiment of the invention be held under friction in the recordings of the upholstery elements. You can do this for example, the recordings as on the inner surface facing the item to be packaged undercut grooves attached to the upholstery elements with the profile of the profile strips be formed with a suitable cross-section.

A trapezoidal, i.e. dovetail-shaped, cross-section is preferred for the profile strips and the grooves into consideration.

However, other cross-sectional shapes can also be provided, for example T-shaped, H-shaped, hexagonal, round or oval cross-section.

In a preferred embodiment of the invention, the profile strips upholstered trained. As a result, the profile strips also offer the packaged item Protection, for example along the edges or on more or less large areas.

In a preferred embodiment of the invention, the cushion elements Plate-shaped with foldable and / or with tenons or teeth interlocking edge areas formed. The upholstery elements can be This makes it easy and cheap to produce and folds out flat for transporting empties or disassemble.

In the context of the invention, there is a particularly favorable packaging frame system on, the upholstery elements in the form of corner areas of the item to be packaged with two legs over two adjacent surfaces and with a flange over the third surface engaging angle profile corners and cushion elements in the form of on one Edge of the piece to be packaged with two legs over the two adjacent ones Surface-engaging profile corners are provided, the legs of the upholstery elements are provided with the recordings for the profile strips. This packaging frame system can still be achieved with additional upholstery elements in the form of along an edge of the piece to be packaged between two angle profile corners in the course of the respective Profile strip to be used angle profile pieces and additional upholstery elements in the form of to be inserted between two profile corners in the course of the profile strip Complement profile pieces, these additional upholstery elements also with recordings are designed for the profile strips.

However, it is particularly advantageous with this packaging frame system, if the upholstery elements in the form of angled profile corners and the as Profile corners formed pad elements between their legs with a hinge are trained. This joint design makes the upholstery elements practical adapt to any shape of a piece to be packaged. Those in the form of angle profile corners trained upholstery elements are then along edges of the to be packaged piece, while the trained in the form of profile corners Upholstery elements extend over surfaces of various shapes and also over edges let begin. Due to the articulation of the upholstery elements, there is no need for them also the additional profile pieces and angle profile pieces, because the articulated Also insert upholstery elements as intermediate pieces in the course of the profile strip and have it applied to the respective area of the item to be packaged. Both The flange can then be designed in the form of angle profile corners made of mitered flange parts that are cut to the joint and attached to each leg be formed with nestable undercut clip connection ..

For simple training that can also be used multiple times can within the scope of the invention at least the by means of joints in flap-shaped State of the folding upholstery elements on their outer surfaces a flexible one Have carrier layer on which the individual plate-shaped parts of the respective Padding element are attached. Such flexible carrier layers can, for example Textile layers or plastic layers provided with a textile insert or at all Be films made of flexible plastic. Otherwise, the upholstery is preferred and the profile strips preferably made of foam sotff, for example foamed thermoplastic material, manufacture and joint formation through Compress the material.

In the example in FIG. 1, a smaller, approximately quarter-shaped one is closed packaging item 24 of which the front surface 21 is a side surface in the drawing 22 and the upper surface 23 are visible, with an upper and a lower one Packaging and protection frame 24. Both packaging and protection frames are in this Example from at the corners of the piece to be packaged 20 in the form of angle profile corners attached cushion elements 30 and in the frame between the four cushion elements 30 extending profile strips 70 formed. The cushion elements 30 grip with their Legs 31 on the peripheral surfaces 21, 22 of the piece 20 and with their flange-like Divide 32 onto the top surface 23 and the bottom surface (not shown) of the piece 20. The profile strips 70 are under friction in the legs 31 of the upholstery elements 30 plugged in. As a result, the two frames 24 are held securely in one piece 20, if this is handled in the further course of the packaging process, for example introduced into a packaging container or shrink-wrapped in packaging film will.

Figure 2 shows a somewhat larger, approximately cylindrical to be packaged Piece 25 (but on a smaller scale than Figure 1).

In this example, around the circumference of the piece 25 are an upper and a lower packaging and protection frame 26 and three middle packaging and Protective frame 27 placed. The top and bottom packaging and protective frames 26 is formed from a number, six in the example shown, upholstery elements 30, with their legs 31 on the circumferential surface 28 of the cylindrical piece 25 are applied and with their flange parts 32 on the upper end face 29 or the Grip the lower end face (not shown) of the cylindrical piece 25. Between the individual upholstery elements 30 are in turn arranged profile strips 70, the are inserted under friction into the legs 31 of the padding element 30. The three middle packaging and protective frame 27 are at approximately regular intervals arranged between the outer packaging and protective frame 26 and made of cushioning elements 50 formed. Each of these cushion elements 50 in turn has two legs 51, the are applied to the peripheral surface 28 of the cylindrical piece 25. Between Upholstery elements 50 in turn extend profile strips 70, which in the legs 51 of the upholstery elements are inserted under friction.

The packaging placed around the cylindrical piece 25 to be packed and protective frames 26 and 27 are thus under friction on the peripheral surface 28 of the cylindrical piece 25 to be packaged held so that the piece with an additional outer packaging cover or other securing elements can be provided. For example, the piece 25 can be shrunk into packaging film will. But it is also possible, at all, from a continuous outer packaging sleeve and around the packaging and protective frames 26 and 27, narrow securing straps made of steel or plastic.

In contrast to FIG. 1, according to FIG. 2, the legs 31 are Upholstery elements 30 are not folded over against one another at an angle of 900, but only about an angle corresponding to the rounding of the circumferential surface 28. One would be similar FIG. 1 shows a larger quarter-shaped piece with a packaging and protective frame occupy, then you could also arrange upholstery elements 30 between the corners and the legs 31 of these upholstery elements 30 stretched out, i.e. at an angle of 1800 let stand to each other. Correspondingly, you can also use larger quarter-shaped Pieces one or more middle packaging and protective frames made of upholstery elements Apply 50, with cushioning elements 50 with their legs 51 around the edges 900 inserts, and with both legs 51 on the two adjacent sides of the the piece to be packaged can be grasped.

As FIG. 3 shows, the upholstery elements 30 are in the form of angle profile corners m essentially L-shaped cross-section, the legs 31 being one part and the flange parts 32 form the second part of the L-profile and substantially are arranged at right angles to each other. In the legs 31 is a continuous Groove 33 with a dovetail, i.e. trapezoidal cross-section attached. the The base line of the trapezoid lies roughly in the middle of the material of the respective leg 31, so that the groove 33 is to be laid against the piece to be packaged Inner surface 37 of the cushion element 36 narrows down. In the middle part of the upholstery element 30 a V-shaped cutout 34 is formed, on both sides of which the legs 31 and the flange parts 32 are arranged. The angle of the V-shaped cutout 34 is preferably 900, so that the legs 31 and the flange parts 32 are attached the sides facing each other have a miter 450, which fold against each other the leg 31 and flange parts 32 allows up to an angle of 900 (cf.

Figure 6). This angle can be changed according to requirements also larger or smaller than 900 can be provided. At the apex 35 of the V-shaped Cutout 34 remains a residual thickness of the material to form the hinge or joint.

This residual material can consist of an additionally applied web 36 flexible material, for example textile or flexible plastic film his (see. Figures 9 to 14).

Figure 4 shows a cushion element 50 for profile corners in stretched out State, i.e. with its legs 51 in a mutual angular arrangement of 1800. The legs 51 of the cushion element 50 are the legs 31 of the cushion element 30 similar.

However, they do not have flange parts, but essentially point rectangular cross-section and a continuous central groove 53, the same Cross-section like the groove 33 of the rister element 30. The cushion element 50 has also a central, V-shaped cutout 54, which is on the two opposite Front sides of the legs 51 each form a miter angle of 45 °. The vertex 55 of the V-shaped cutout 54 leaves a residual thickness of the material as There are hinge elements, which are also applied in this case by an additional Web 56 can be made of flexible material.

Figure 5 shows a profile strip 70, which in principle within the scope of the invention can have any cross-sectional shape with an undercut. In the illustrated For example, the profile strip 70 has a trapezoidal, i.e. dovetail-shaped, cross-section. A length marking 71 is applied to the narrow side of the profile strip 70. In this way, the profile strip 70 can be in basic lengths manufactured and be deflected in required pieces for the respective packaging purposes. The profile strip 70 can consist of any material. One is preferred to them however, from flexible material to form the profile strip 70 itself to give a cushioning effect. For example, the profile strip 70 can foamed, thermoplastic plastic. If it's because of the material the profile strip 70 is not possible, the length marking 71 directly on the narrow side 72, it is entirely possible to shape or print on the narrow side 72 also to apply a strip carrying the length marking 71, in particular stick on. The angle profile strip 70 fits with its cross section under friction into the grooves 33 and 53 of the cushion elements 30 and 50, respectively.

FIG. 6 shows one formed from a cushion element 30 according to FIG Corner profile corner with ProfileMiste 70 pushed into one leg. The bend is 900 in this case, so that the V-shaped cutout 34 is completely closed is.

The angled profile corner thus formed thus has two legs 31 and a closed flange 32. The legs 31 thus grip - as in FIG. 1 shows - over two adjacent side surfaces 21, 22 of a quarter-shaped to be packaged Piece 20, while the closed flange 32 over the top or bottom this to be packaged piece 20 engages. The remaining material layer serving as a hinge or additional support 36 forms an effective edge protection in this state.

FIG. 7 shows a cushion element 50 according to FIG. 4 in relation to a profile corner angled state in which the two legs 51 under complete closure of the V-shaped cutout 54 in a diaper of 900 to each other. The grooves 53 are also at right angles to each other, according to the illustration of Figure 7 in which a groove a profile strip 70 is inserted under friction.

In the illustration of FIGS. 3 to 7, section lines are at 38 and 58, respectively recognizable, which indicate that the cushion element 30 or the cushion element 50 from a plate-shaped element can be folded, as shown in the figures 8 to 14 can be seen. However, the cushion elements 30 and 50 with the from Figures 3 and 4 apparent profile be solidly shaped. However has the training shown in Figures 8 to 14 a number of special advantages. In particular with regard to easier formability and better possibility of the flat Unfolding the respective cushion element 30 or 50.

As can be seen from FIGS. 8 to 14, the cushion element 30 is with two longitudinal hinges 39 and 40 and one through the apex 35 of the V-shaped Recess 34 formed transverse hinge can be folded out into a plane in the form of a plate. The cushion element 30 is formed in such a way that six sections on a flexible carrier layer 36, for example a textile material layer or film made of flexible plastic. These six sections are two identical Leg pieces 31, two leg side strips 45a and 45b, which are attached to each other facing end faces are beveled with 450. The leg sidebar 45a carries on this beveled side a bracket attachment 43, while the leg side strip 45b has a bracket recess 44 at the corresponding point. On the side edge the edge adjacent to the respective leg piece 31 carry the two leg side strips 45a and 45b teeth 46, which are in corresponding recesses 47 in the side edge of the Grab leg pieces 31. Conversely, the leg pieces 31 have a tooth 46 which into a corresponding recess 47 of the respective leg side strip 45a or 45b matures. As can be seen from FIG. 8, the teeth 46 are somewhat wider than the recesses 47 formed so that when the leg side strips 45a and 45b are folded over 900 the teeth 46 due to the manufacture of the cushion element 30 from resilient Material are pressed into the respective recesses 47 with friction, and the leg sidebars 45a and 45b in folded position keep. The teeth 46 and recesses close to the outside and inside 47 abutment surfaces 38 beveled at 45 °.

As can be seen from FIGS. 8 to 14, each of the leg side strips carries 45a and 45b on the outer edge facing away from the leg parts 31 one after externally increasing bevel 48. This bevel 48 forms when the leg side strips are folded in 45a and 45b the one, tapering towards the interior of the buffer element 30 Side surface of the dovetail groove 33. The inner surface of the cushion element is As shown in FIGS. 9 to 11, through the side surface 37 of the leg side strips 45a and 45b formed I On the other side of the leg parts 31 are flange side strips 49a and 49b are attached, which are bevelled at their opposite sides at 45 ° are. The flange side portion 49a carries on this beveled edge while in the A matching bracket recess 42 is attached to the flange side part 49b. Along the connecting edges to the flange parts 31 are again inclined surfaces on both sides 38, teeth 46 and recesses 47 matching these teeth 46, like this has been described above in relation to the leg sidebars 45a and 45b. In the end carries each of the flange side pieces one sloping outwards increasing bar 48, which in the folded state of the flange side parts 49a and 49b form the second side surface of the dovetail groove 33.

The clip parts 41, 42 and 43, 44 are provided so that the Upholstery element 30 can be assembled to form an angle profile corner. being it is folded around the apex 35 of the V-shaped recess by 90 °. Included the clip lugs 41 and 43 are in the corresponding clip receptacles 42 and 44 used.

The upholstery element 30 then forms a stable angle profile corner element.

The cushion element 50 is constructed in the same way as in FIG Connection with Figure 8 to 14 for the cushion element 30 explained, with the only one The difference is that on both sides of the leg parts 31 the same leg side strips 45a and 45b are provided, so the flange side parts 49a and 49b by leg side strips 45a and 45b are replaced.

FIG. 15 shows a possible modification for the formation of the Upholstery element provided for angle profile corners. Hereafter this has been modified Upholstery element 30 'both in its legs 31' and in its flange parts 32 'grooves 33', which in the example shown are also trapezoidal, i.e. dovetail-shaped Have cross-section. This enables also on the end faces of the pieces to be packaged profile strips 70 can be provided, which are then inserted into the flange parts 32 '. This preserves the peripheral edge of a piece to be packed an even better protection and the corner profile corners receive improved hold, particularly in the area of their flanges 32 '.

As FIG. 15 shows, such a modified cushion element can also be used 30 'for this purpose, manufactured essentially in the form of a plate and folded up for use to become. This becomes clear in FIG. 15 at the contact lines 38 'and 38 ".

If one compares FIG. 15 with FIG. 8, it can be seen that the same Leg side strips 45a and 45b can be provided as in the example of FIG. The leg parts 31 'are, however, on the side to which the flange parts 49'a and 49'b are attached, with one forming the second side surface of the groove 33 ' Bar 48 'formed. The leg parts 49'a and 49'b are in this example each built in two parts, with a pivoting sidebar 49 "a and 49" b, which are constructed similarly to the leg side strips 45a and 45b.

The flange parts are on the edge articulated to the leg parts 31 ' 49'a and 49'b formed with a bar 48 ″, which is provided with inclined surfaces and, if necessary, l Toothings on the outer surface of the bar 48 'of the leg parts 31' fits, and on the other Side one side surface of the in the flange parts 49'a and 49'b formed longitudinal groove 33 '. Otherwise the structure is the same as in the example of FIG. 8, the clamping elements in the illustration 15 are omitted for the sake of clarity.
