Description

DESCRIPTION

Application ring for a pallet box and pallet box.

[0001] The invention relates to an application ring for a pallet box with standard dimensions of a grid box 5, with four side walls, where at least one side wall has retaining elements for a flexible compartment configuration, where two opposite side walls are formed as a double wall from an internal and external cover after the formation of hollow chambers or hollow spaces between the internal and external cover configured of plastic surface parts, and where the two permanent side walls are formed at least by sections through rigid sleepers, which are connected to the 10 plastic surface parts, as well as a pallet box with an application ring of this type.

[0002] US 2005/0155971 A1 discloses a pallet box with an application ring with four side walls, where at least one side wall has retaining elements for a flexible compartment configuration. Two opposite side walls of the application ring are formed as surface portions 15 of double wall plastic. A permanent side wall comprises a rigid frame with stringers and sleepers. The stringers oriented in the vertical direction are connected to the adjacent side walls.

[0003] From document DE 198 06 075 A1 a pallet box with a folding application ring is known, which extends in the installed state between a bottom and a cover. The folding application ring has four side walls 20, which can be joined for an empty transport of the pallet box and can be deposited at the bottom. The lid closes the bottom with the attached application ring on it.

[0004] Another pallet box of EP 0 286 271 A2 is known. The pallet box comprises a bottom as well as a lid. In addition, four side walls are provided, which are made insertable both together and in the bottom. The cover can be placed on the four side walls that form an application ring. Both the bottom and the side walls are produced with double cover from plastic plates.

[0005] Another pallet box of WO 97/31830 A1 is known. The pallet box is intended for the transport of automobile supply parts and has a pallet bottom, which can be manipulated through a forklift 30 with fork. A collapsible wall ring is placed on the bottom of pallets. A lid is placed on the wall ring, which closes the inside of the wall ring. The wall ring has four surface side walls, which are foldable by edge hinges. Retaining rails are provided internally on two opposite side walls, to which a flexible compartment configuration for the accommodation of the corresponding automobile supply parts is fixed. 35

[0006] It is the object of the invention to create an application ring and a pallet box of the initially mentioned type, which are easily produced and have a stable structure.

[0007] This task is solved for the application ring by the features of claim 1. Since the plastic surface parts are produced in a double sheet method, the plastic surface parts are configured with double wall to from an internal cover and an external cover after the formation of hollow chambers or hollow spaces between the internal cover and the external cover of the plastic surface part. The concepts "internal" and "external" refer to the installed functional position of the application ring, where "internal" defines the side turned inwardly of the application ring and "external" defines the side turned outwardly 45 of the application ring . The solution according to the invention is particularly advantageous for application rings whose size is in accordance with the standardized grid boxes for housing and transport of supply parts for the automotive industry.

[0008] According to the invention, the wall sections are provided with transverse grooves formed in a single piece, which are arranged divided over the height of the wall sections, in which the sleepers are embedded and fixed by means of fixing elements, where each transverse groove is associated with a termination recess arranged at the same height, which in the rectangular constructed state of the application ring accommodate the corresponding frontal ends of the rigid sleepers. Thus the sleepers do not protrude above a corresponding surface contour of the plastic surface parts. The configuration 55 allows an arrangement of the sleepers that occupy little. The interleaving of the sleepers additionally guarantees a reinforcement of the wall sections of the plastic surface parts.

[0009] Advantageously, the application rings are intended to be placed in a corresponding grid box or a comparable pallet box made from a plastic material. In both cases the side walls 60 of the application ring adjust directly in the functional position installed to the corresponding internal walls of the grid box or the pallet box. Alternatively, it is provided according to the invention that the application rings be made directly as a wall ring for corresponding pallet boxes. In this case, a corresponding application ring with its lower side is placed on a corresponding pallet bottom. An upper side of the application ring is closed by a supportive cover. The lid is made in relation to the bottom of 65 pallets so that it can also be placed directly on the pallet bottoms. The manufacture of

plastic surface parts means in a double sheet method, that two plates of a thermoplastic plastic are made available and introduced into an injection mold, in which simultaneously by drawing both plastic plates and corresponding welding of the plastic plates on its edge as well as in intermediate segments with each other the flat element of double cover is produced. The sleepers form at least sections of the side walls of the application ring and are preferably configured as a hollow metal profile, particularly of a steel alloy.

[0010] In the preparation of the invention, the plastic surface parts are provided with fold lines extending from the edge, to allow folding and unfolding of the application ring. The fold lines that extend from the edge are preferably formed by the sheet hinges, which are formed in a single piece with the plastic surface parts.

[0011] In a further configuration of the invention at least one of the plastic surface parts is provided with a folding section, which is connected to the flat plastic element by means of a sheet hinge that extends transversely. The folding section is connected to the flat plastic element 15 only in the area of the sheet hinge. Through the fold section it is possible to gain access to the interior of the application ring. Preferably, the sheet hinge is arranged so that it is also hardened and reinforced in the folded state of the respective fold section of the side wall of the plastic surface part. In the raised state the fold section closes the access opening inside the application ring. Through the access opening, the introduction or removal of a corresponding transport product 20, particularly a car supply part, is allowed.

[0012] In a further configuration of the invention the sleepers are provided with the retaining means for the flexible compartment configuration. This avoids retention rails or additional carriers for flexible compartment configuration. The sleepers are preferably provided with internal longitudinal grooves 25, in which the corresponding sliding or carriage elements can be moved, with which the flexible compartment configuration is connected. The slots of the sleepers are preferably made according to the method of curtain rails. Also the sliding or carriage elements for retention of the flexible compartment configuration are configured according to the method of a curtain suspension.

 30

[0013] In a further configuration of the invention, the folded areas that extend from the edge into areas of angle of the application ring respectively have two spaced apart lines that extend parallel, which delimit between them a support backing which defines in folded state of the application ring a free space between corresponding wall sections of the plastic surface parts. This ensures that sufficient space is also available in the folded state of the application ring to accommodate the flexible compartment configuration between the corresponding wall sections of the plastic surface parts, thus ensuring that the flexible compartment configuration is not move away from the crossbar before joining or folding the application ring. The compartment configuration can remain attached to the side walls rather also in the folded state of the application ring, particularly with the sleepers.

 40

[0014] In a further configuration of the invention the fold lines are configured by sheet hinges, which are flanked inside by peripheral miter surfaces of the plastic surface parts, where 45 ° miter angles are particularly provided. The peripheral miter surfaces are supported in a folded state, so that the corresponding wall sections of the plastic surface parts are oriented relatively rectangular to each other and relatively to the support bridges in the folded state.

[0015] The application ring according to the invention can be placed particularly advantageously in a pallet box, particularly in a grid box consisting of steel. In this case the application ring is placed from above, e.d. from the open side of the pallet box, until its bottom edge is on the bottom 50 of pallets. The side walls of the application ring are aligned in height and width with the side walls of the pallet box so that in the installed functional state of the application ring the side walls are adjusted essentially superficially to the inner walls of the box of pallets. The pallet box has the dimensions of a standardized grid box, which is 835 mm wide, 1240 mm long and 970 mm high. The pallet box has a loading means for the technique of accommodation, transport and extraction. 55 Each pallet box has four feet on the underside of its pallet bottom, which should allow a forklift ramming from all four sides.

[0016] According to the invention the application ring is sized for a pallet box with the standard dimensions of a grid box, such that it can be placed in the pallet box and is arranged erect in an internal area of the custom pallet box. The pallet box may consist of plastic or steel grid and preferably has standard dimensions of an euro grid box, which is particularly used in the automobile supply branch. The sizing of the application ring in its functional state installed in such a way that it is arranged in an erect way to measure in the internal area of the pallet box, allows positioning the application ring without additional fixing means in the pallet box. The application ring completely fills the inner area of the pallet box in the installed functional state, so that its outer walls are

arranged mostly without play and directly adjacent to the inner walls of the pallet box. This allows a particularly simple insertion and removal of the application ring. In addition, the pallet box and the application ring can be handled independently of each other in an empty state. Wooden pallets with the corresponding standard dimensions are also provided as a pallet box in the sense of the invention, as well as combined wooden and steel grid constructions or also combined plastic and wooden constructions.

[0017] The task at the base of the invention is solved by the features of claim 7 for the pallet box.

 10

[0018] In the embodiment of the pallet box according to the invention the application ring is made foldable or foldable and dimensioned in a folded or folded state such that the application ring is housed erect or lying in the box of pallet Preferably, several application rings can be transported in a folded or folded state in the pallet box.

[0020] An application ring 1 for a pallet box is composed according to Fig. 1 to 7 of two plastic surface parts 3 as well as several sleepers 4, as described in detail below. The application ring 1 has a rectangular bottom base and forms a total of four side walls A, B, C, D. Within the four side walls A to D, a flexible compartment configuration 2 is provided in the application ring 1, which creates several ties of a textile surface track. The ties form fold-type bags and are arranged parallel to each other. The flexible compartment configuration 2 can be fixed or hung with the aid of tensioning ropes or by hooks or eyelets fixed in the compartment configuration 2 to the internal parts of the application ring 1 and thus at least two opposite side walls C are held, D of the application ring 1.

 Four. Five

[0021] Both plastic surface parts 3 opposite each other are configured identically with each other. Each flat plastic element 3 is produced with double wall double wall construction. In this case, each of both parts of the plastic surface 3 has an internal cover turned towards the center of the application ring 1 as well as an external cover facing outwards, which are produced in a fundamentally known manner by common drawing in a double method. sheet after the formation of cavities and seams joining the respective flat plastic element 3.

[0022] With the aid of Fig. 7, the configuration of the plastic surface part 3 can be well recognized. The opposite plastic flat element 3 of the application ring 1 is configured identically. Each flat plastic element 3 has a section of the side wall 5, which is configured by means of a fold line 6 that extends from a foldable divided edge. The side wall section 5 is provided in the area of its upper half with a rectangular cutout, which can be partially closed by a fold section 7. The fold section 7 is joined in one piece with the flat plastic element 3 and is joined in the area of a sheet hinge S, which extends transversely relatively to the upper axis of the plastic surface part 3, with the side wall section 5. Also the fold section 7 has a fold line 6a 60 aligned coaxially with the fold line 6. Both the fold line 6a and the fold line 6 are formed respectively by a sheet hinge taken from the mold in one piece, which is aligned with the outer cover of the surface part plastic 3. Starting from the inner cover, both the side wall section 5 and the fold section 7 have peripheral miter surfaces not mentioned in more detail, q They flank the fold line 6, 6a on both sides in a 45 ° angular alignment. The sheet hinge S, with which the fold section 7 is retained in the side wall section 5, is provided on the height of the cover

internal of the plastic surface part 3. On the peripheral sides opposite the side wall section 5 respectively connects a fold line 10 which extends from the edge through the total height of the side wall section 5, such as the which is carried out on the height of the outer cover of the foil hinge provided. From the inner cover each of both fold lines 10 is flanked on opposite sides of the side wall section 5 of peripheral miter surfaces, which are made identically to the peripheral miter surfaces 5 of the fold line 6.

[0023] Respectively outwards, to each fold line 10 connects a narrow support back 11, which extends through the total height of the plastic surface part 3 and is limited outwardly by another fold line 9. The fold line 9 in the installed functional position of the application ring 1 forms 10 respectively an angle of the application ring 1. The fold line 9 is also formed by a sheet hinge placed in the area of the outer cover, which passes over the total height of the plastic surface part 3 and is oriented parallel to the fold lines 10, 6. The sheet hinge 9 is flanked from the inner cover by peripheral miter surfaces oriented at an angle of 45 °. The opposite outer wall sections of the plastic surface part 3 are formed with wider retention sections 8 in front of the support back 11, which form extended wall sections over the total height of the plastic surface part 3. Laterally outwardly each retaining section 8 has a peripheral miter surface oriented at an angle of 45 °. The retention sections 8 are provided with transverse grooves 14 formed in one piece, which are arranged divided over the height of the retention sections 8. In the exemplary embodiment shown, a total of six transverse grooves 14 are provided, which are formed 20 for accommodation of 4 rigid sleepers. Each transverse groove 14 is associated inside the support backing 11 with a termination recess 15 arranged on the same height, which in the rectangular constructed state of the application ring houses the corresponding front ends of the rigid sleepers 14.

[0024] Since a sheet hinge S is provided that extends transversely of the fold section 7 25 in the area of the inner cover of the plastic surface part 3, the fold section 7 can be rotated 180 ° towards inside, whereby its fold line 6a is oriented opposite to this fold line 6 of the corresponding side wall section 5 (Fig. 2, 5, 6). In this way the fold section 7 forms in the folded inward state a reinforcement and hardening for the side wall section 5.

 30

[0025] In the transverse grooves 14 of both opposite plastic surface parts 3 are inserted respectively on opposite sides of the application ring 1 six rigid sleepers 4, which in the embodiment shown are performed as a hollow metal profile with quadrangular cross section . The sleepers are preferably produced from steel. However, it is also possible to manufacture the sleepers 4 from a light metal, particularly an aluminum alloy, or a fiber bonding material. By means of the crosspieces 35 4 both opposite plastic surface parts 3 are joined, as is well recognized with the aid of Fig. 1 to 3. The crosspieces 4 are respectively configured in their cross-sectional profile, such that they can be embedded flush in the transverse grooves 14 provided with the quadrangular light cross section. For fixing the sleepers 4 in the transverse grooves 14 of the opposite retaining sections 8 of the plastic surface portions 3, fixing means in the form of riveted joints or the like are provided. The fixing means are preferably effective in positive bonding. It is also possible to provide fittings and / or pre-formed fittings in one piece as fixing means.

[0026] As can be recognized with the aid of Fig. 2, the sleepers 4 are flush in the retention sections 8 of the opposite plastic surface parts 3, so that they do not protrude above an internal surface. or internal contour of retaining sections 8 inwards. The sleepers 4 are provided with longitudinal grooves 12 open towards the center of the application ring 1, in which corresponding retaining elements 13 of the hooks, eyelets or tensioning ropes of the compartment configuration 2 are retained.

 fifty

[0027] As can be recognized with the aid of Figs. 5 and 6, the peripheral miter surfaces flanking the fold lines 9 of the plastic surface parts 3 form support surfaces in the installed functional state of the application ring 1 , to assist perpendicular alignment of application corners 1.

[0028] The application ring 1 is transferable with or without compartment configuration 2 integrated in a folded rest state according to Figs. 3 and 4. For this purpose the fold sections 7 are easily rotated 180 ° upwards again from its hardening position folded inwards, whereby according to Fig. 7 they align with the outer surface contours of the respective side wall section 5. Next the side wall sections 5 are pressed inwardly around their line of intermediate fold 6, 6a towards the center. As soon as a left and right half of each side wall section 5 including the fold sections split into 60 two 7 meet each other with their outer surface sides, the folded rest position of the application ring 1 according to Fig. 3 and 4. As can be recognized with the aid of Fig. 3 and 4, because of the support back 11 there is a free space between the side walls C, D formed by the sleepers 4 at least in a part of its width and the folded side wall sections 5, since the retention sections 8 are oriented at 90 ° with respect to the support backs 11 and also the side wall sections 5 are supported 65 on the sleepers 4 at approximately 90 ° internally to the backrest of support 11. The fold lines and with them

the corresponding sheet hinges are flexibly shaped, so that a minimally oblique orientation of the folded side wall sections 5 according to Fig. 4 is allowed. Thus the opposite side wall sections 5 can overlap each other with the side walls. A, B, as can be recognized with the aid of Figs. 3 and 4. The clearance between the sleepers 4 and the associated retention sections 8 of the opposite side walls C, D is sufficient to accommodate the compartment configuration Flexible 2 in its 5 folded state.

[0029] Both side walls C, D are therefore formed by the respective two retaining sections 8 of the opposite plastic surface parts 3 as well as by the six sleepers 4, which are embedded in the transverse grooves 14 of both sections of both retention 8 of the opposite 10 plastic surface parts 5.

[0030] The application ring 1 has high stiffness and stability due to the type of double sheet construction of the plastic surface parts 3 as well as because of the rigid sleepers 4. Since the sleepers 4 completely form the walls opposite sides C, D between the opposite retention sections 8 of the 15 plastic surface parts 3, weight savings are achieved. Since the sleepers 4 are arranged parallel to each other in a common wall plane, but with distance between them, it is possible to look inwards in the area of the side walls C, D through the sleepers 4 inside the ring of application 1.

[0031] A pallet box H according to Fig. 8 to 12 serves to accommodate at least one application ring 1 20 according to Fig. 1 to 7 in its installed functional position (Fig. 8) or in its position of folded rest (Fig. 9 and 12). The pallet box H has standard dimensions, which are used in the automotive industry or in the field of household appliances. The pallet box H is made of plastic in the embodiment shown and with at least one foldable side wall provided. As can be recognized with the aid of Fig. 8, an application ring 1 can be placed in the installed functional state including its compartment configuration 2 from above in the pallet box 25 open at the top. The application ring 1 adapts in such a way to the internal dimensions of the pallet box H, that in the installed functional state it is essentially connected without play to the four side walls of the quadrangular pallet box H at least in large part. This avoids additional fixing means for securing the application ring 1 in the functional state installed inside the pallet box H. 30

[0032] As can be recognized with the aid of Fig. 9, the application ring 1 can also be folded. This folding can be carried out both inside the pallet box H and outside the pallet box H. In the folded state, the application ring is arranged erectly in the pallet box H. According to Fig. 10 and 11, it can be removed easily up. The stability of the application ring 1 also allows easy operation in the folded rest state 35, as soon as the application ring 1 can either be placed erect in the pallet box H or it can be easily removed upwards from the case pallets H (Fig. 10 and 11). In the folded functional state it is possible to accommodate fourteen rings of application 1 in total adjacent to each other erect within the pallet box. In the empty and folded state, these many application rings 1 can be transported with a pallet box H. No additional fixing means are necessary for this. Rather the fourteen application rings 1 are stacked 40 adjacent to each other in such a way that they complete the internal dimensions of the pallet box H.
