Description

Title of the invention: Windshield wiper blade packaging device and system of a windshield wiper blade packaging device. SCOPE OF THE INVENTION

[0001] The present invention relates to a windshield wiper packaging device for at least two windshield wipers comprising an overpack. STATE OF THE ART

[0002] Such a windshield wiper packaging device receiving at least two windshield wiper blades and having an overpack is already known.

[0003] DESCRIPTION AND ADVANTAGES OF THE INVENTION

[0004] The present invention relates to a windshield wiper packaging device comprising at least two wiper blades with an overpack, characterized by at least one assembly package for connecting at least two wiper blades and for arranging the wiper blades in the overpack having at least two parallel folds extending over the entire length of the assembly package which delimits at least one through passage.

[0005] The windshield wiper packaging device according to the invention advantageously ensures the safe transport of at least two wiper blades. Advantageously, the two wiper blades in the overwrap are protected or secured, in particular, against slippage. Particularly advantageously, the two wiper blades are protected against damage during transport. The assembly packaging prevents the wiper blades attached to the positioning base from being ejected from it, for example, by the rotation of the wiper blades during movement of the overwrap. Particularly advantageously, the wiper blades, especially their wiping edges, are thus perfectly protected.

[0006] The term "wiper blade" preferably designates at least one part, in particular a sub-assembly, of a wiper. The wiper blade is intended for use on a vehicle. The wiper blade constitutes a part of the wiper assembly. Preferably, the wiper blade, particularly as a part of the wiper assembly, is used for cleaning a surface, preferably the surface of a window, in particular a vehicle window.

[0007] Preferably, the windshield wiper blade is designed to clean a window, particularly a vehicle window such as the windshield, preferably by being coupled to the vehicle's wiper arm drive. The fact that an object is designed to perform a specific function means that this object carries out or performs this function. determined in at least one state of application or operation. The term "state of operation" means the state in which the wiper arm device is ready to operate for a wiping operation or wiping mode or is in a wiping mode in which the wiper blade unit, preferably the wiping lip, of the wiper blade in particular of the wiper, is driven on the vehicle window against which it is applied.

[0008] The term "wiper pack device" refers to a pack device that holds at least two wiper blades. The term "package" refers to an enclosure, in particular a box designed to protect the contents of the pack from damage and which is only used in a temporary position, such as during transport or storage. Preferably, the wiper pack device is designed to store the wiper blades securely.

[0009] Preferably, the windshield wiper packaging device includes an overpack to protect the contents of the packaging, in particular the windshield wiper blades, against dirt or damage.

[0010] Preferably, the overwrap is at least practically rectangular in shape to ensure the protection of the transient state or the stacking unit. The term "overwrap" refers in particular to packaging made of a material that is particularly advantageous from an ecological point of view, especially cardboard or paper or an environmentally friendly material, and which constitutes the outermost packaging or the boundary between the wiper arm packaging device and the environment. The overwrap has openings on its front faces, particularly on the smaller front face, which is at least practically square.

[0011] Preferably, the two wiper blades are connected, in particular by a shape connection via the assembly package, or are fixed to each other, in particular in a rigid manner. The assembly package is folded or bent to secure the two wiper blades.

[0012] Preferably, the assembly package has at least one through-hole to receive the two wiper blades and secure them relative to each other. The through-hole is rectangular in shape, in particular with at least four margins that are practically perpendicular to each other and are formed, in particular, by the assembly package. The term "connected" refers, in particular, to the holding or securing in place of two objects, such as wiper blades, relative to each other.

[0013] Preferably, the assembly packaging is designed to protect the wiper blades installed on a base plate and prevent them from slipping on this plate or from being able to slide beyond this plate.

[0014] The assembly package preferably has two parallel folds, in particular two folds for folding along the parallel folds. The term "parallel folds" refers in particular to a notch, an edge, or a fold of the assembly package, these folds being parallel to the outer edge or the edge delimiting the opening, or to another parallel fold. Alternatively, a folding guide parallel to an outer edge or to an edge delimiting the through-opening, or to another parallel fold, can also be provided, either optically, perforated, or slotted.

[0015] Preferably, the folds of the lateral areas or ends of a spatial structure of the assembly packaging are at least practically perpendicular, in particular with the smallest angle greater than 45°. The parallel folds, in particular the spatial structure of the assembly packaging, are provided to connect the assembly packaging to the overpack by a form connection or to fix it to the overpack.

[0016] The two folded ends are on the side walls of the overpack.

[0017] Preferably, the two folded ends of the assembly packaging are folded in the same direction, in particular in a direction that moves away from the wiper blades.

[0018] Preferably, the parallel folds are parallel to the length of the assembly package.

[0019] The term "assembly packaging length" refers in particular to the extension in the principal direction of extension. The term "principal direction of extension" of an object refers in particular to a direction parallel to the longest edge of the smallest geometric parallelepiped that closely and completely surrounds the object. Preferably, the assembly packaging is distinct from the overwrap.

[0020] According to another feature, the through-recess is designed as a receiving area / connecting element to receive at least two wiper blades. Advantageously, the two wiper blades are secured or blocked against slippage within the overpack. The two wiper blades are thus protected against damage during transport. The assembly package is particularly easy to assemble. The wiper arm connecting elements can be joined to secure the two wiper blades in the overpack, particularly with the assembly package. Each of the two wiper blades has a wiper arm connecting element to connect the wiper blade, particularly by means of a shaped connection, to the wiper arm. The wiper arm connecting elements have a front side, in particular an outer side shaped convex optimized particularly from an aerodynamic point of view and a rear side with a concave shape, particularly the inner side.

[0021] The receiving zone-connecting element is formed by the through recess.

[0022] Preferably, the receiving area – connecting element – ​​has a practically rectangular shape. The receiving area – connecting element, at least practically in the middle, is provided in particular in the main extension plane of the assembly packaging. The receiving area – connecting element, in its installed state, surrounds the two connecting elements of the wiper arm at least partially. The term "main extension plane" of a component refers in particular to a plane that is parallel to the largest lateral surface of the smallest parallelepiped that closely encloses the component and passes in particular through the center of the parallelepiped.

[0023] According to another feature, the through-hole secures the two wiper arm connecting elements of the two wiper blades in a plane by means of a form connection. This advantageously saves packaging material, in particular the amount of material from which the wiper arm connecting elements are made. Advantageously, the two wiper blades, and in particular the wiper arm connecting elements, are attached in a particularly simple manner, especially by means of a form connection.

[0024] The plane for attachment by a form connection is at least practically parallel to the main extension direction of the wiper blades. The plane is formed by the main extension direction of, in particular, the unfolded assembly package, the through-recess, or the receiving area / connecting element. In particular, the wiper arm connecting elements of the wiper blades are each longer than the through-recess. The through-recess has a width substantially twice that of the wiper arm connecting elements of the wiper blades. In particular, the two wiper arm connecting elements together are substantially as wide as the through-recess.

[0025] According to another characteristic, the assembly packaging is made of the same material as the overwrap. Advantageously, this results in savings, particularly in material and manufacturing costs. The expression "made of the same material" means that the material of the assembly packaging belongs to the same material group as that of the overwrap. For example, the "paper" material group is used for both the assembly packaging and the overwrap; thus, paper, lightweight board, or heavyweight board is used. Preferably, the material of the assembly packaging and the overwrap is identical, and in particular, it is the same raw material.

[0026] According to another characteristic, the assembly packaging is made of a biodegradable material. Disposal of the assembly packaging and the overwrap is therefore economical. The term "biodegradable" means, in particular, that microorganisms allow the material to be eliminated in the form of elementary components such as carbon, oxygen, hydrogen, and others.

[0027] According to another characteristic, the assembly package in its unfolded state has an outer contour that is at least practically rectangular. This saves material. It reduces the cost of the material and the cost of manufacturing. The term "unfolded" means that the assembly package is as flat as possible, and the thickness of the assembly package is defined at least practically by the thickness of the material. The term "outer contour" refers to the outer boundary, in particular the contour of the assembly package. The outer contour, in particular the macroscopic outer shape, which is practically defined by the two longest lateral edges, is rectangular or rectangular in shape. In particular, the macroscopic shape does not have fillets, rounded corners, small grips, or similar shapes.

[0028] According to another feature, the through-hole is delimited at least practically by a rectangular outer contour. The connection by shape is achieved in a particularly simple manner.

[0029] According to another feature, the through-hole is parallel to the longitudinal axis of the assembly package, being limited to a maximum extension corresponding to at least 75% of the maximum extension of the assembly package, parallel to the longitudinal axis; the through-hole is limited perpendicular to the longitudinal axis of the assembly package at a maximum extension representing at least 50% of the maximum extension of the assembly package, perpendicular to the longitudinal axis. This provides the advantage of a particularly robust assembly package. The term "longitudinal axis" refers in particular to the axis parallel to the principal direction of extension of the assembly package.

[0030] The assembly package in its unfolded state is planar symmetrical with respect to a mirror plane, preferably with respect to at least two different mirror planes. The longitudinal axis of the assembly package corresponds to the principal direction of extension of the assembly package in its unfolded state. The through-cutout is parallel to the longitudinal axis of the assembly package, limited to a maximum extension that preferably represents at least 90%, preferably at least 60%, and advantageously at least 50% of the maximum extension of the assembly package parallel to the longitudinal axis. Perpendicular to the longitudinal axis of the assembly package, the through-cutout has an extension maximum which represents, preferably, at least 75%, preferably at least 60%, advantageously at least 40% of the maximum extension of the assembly packaging perpendicular to the longitudinal axis.

[0031] According to another feature, the through-hole is located between at least two parallel folds. This advantageously improves strength. The two wiper blades are thus fixed particularly effectively. The term "between" means that the through-hole, in particular the receiving area / connecting element in the main extension direction of the connecting package, is delimited on at least two sides by the parallel folds, being provided in particular between or beside the parallel folds.

[0032] According to another feature, the through-hollow is directly adjacent to the two parallel folds, which improves strength. The two edges delimiting the through-hollow in the longitudinal direction of the assembly package meet at least practically at one parallel fold each. The parallel folds result from folding the assembly package along the longitudinal axis of the through-hollow.

[0033] According to another feature, the unfolded assembly package has an outer contour with truncated corner areas. This simplifies the placement of the assembly package within the overwrap. The corner areas of the outer contour are truncated, in particular, at an angle of at least 45° to the longitudinal direction of the assembly package, which decreases in the longitudinal direction. Alternatively, the angle parallel to the longitudinal direction of the assembly package may be at least 5°, advantageously at least 15°, and particularly advantageously at least 30°. The fillet is achieved by removing material, in particular by cutting the corners. Alternatively, the corners may also be folded, in particular by 180° around one of the two sides.Preferably, the outer contour with folded corners facilitates the assembly of the packaging within the overwrap.

[0034] The invention also relates to a system comprising a windshield wiper packaging device and at least two wiper blades, each having a wiper arm connecting element, these connecting elements being at least partially traversed by the through-hole. The two wiper blades are thus stored and protected. Damage to the two wiper blades is prevented, particularly from shocks such as an impact on the overwrap.

[0035] Assembling the packaging is quick and easy. Passing the two wiper arm connecting elements through the through-hole creates a connection by shape between the two wiper arm connecting elements and the assembly packaging. Advantageously, the assembly packaging limits the direction movement of the two wiper blades in directions parallel to their main direction of extension.

[0036] According to another feature, the two wiper blades are packaged so that the rear sides of the respective wiper arm connecting elements face each other. This simplifies assembly and creates a particularly strong connection by form, with the advantage of simplified mounting. The term "front side" refers in particular to the side exposed to the wind during operation, especially a convex side; the term "rear side" refers to the side not exposed to the wind during operation, especially a concave side.

[0037] The wiper packaging device according to the invention and the system according to the invention are not limited to the application and embodiment described above. In particular, the wiper packaging device according to the invention and the system according to the invention may have a different number of elements, components, or units than those described above to ensure their described operation.

[0038] Furthermore, the value ranges given in the description can be used in any way. Brief description of the drawings

[0039] The present invention will be described in more detail below with reference to embodiments of a packaging device according to the invention shown in the accompanying drawings, in which:

[0043] DESCRIPTION OF METHODS OF IMPLEMENTING THE INVENTION

[0044] Figure 1 shows a schematic perspective view of a system 32 with a wiper blade packaging device. The system 32 comprises two wiper blades 10. The system 32 has a positioning base 40. The wiper blades 10 are placed in the positioning base 40. The positioning base 40 is made of plastic. The positioning base 40 is made of a biodegradable material. Alternatively, the positioning base 40 can also be made of cardboard. The positioning base 40 protects the two wiper blades 10 by means of a form-fitting connection to prevent them from slipping into the overwrap 12 of the wiper blade packaging device. The positioning base 40 protects the wiper blades 10, in particular the wiper blade lips 10, against damage during transport. The geometric shape of the positioning base 40 is viewed in a direction perpendicular to the principal plane of extension of the positioning base 40, at least practically the same size as the lateral surfaces of the overpack 12, in particular, the lower side of the overpack 12.

[0045] The wiper packaging device includes the overpack 12. The wiper packaging device includes an assembly package 14. The assembly package 14 holds the wiper blades 10 together. The assembly package 12 is designed to hold the wiper blades 10 in the respective positions provided in the overpack 12. The assembly package 14 holds each of the wiper blades 10 in a predetermined position in the positioning base 40. The wiper blades 10 each have a wiper arm connecting element 34. The assembly package 14 is designed to hold the wiper blades 10 by a connection through the shape with the connecting elements 34 of the wiper blades 10 relative to each other. In the packaged state of the system 32, the two connecting elements 34 of the wiper blades 10 pass through a through recess 18 of the connecting packaging 14.Each wiper arm linkage element 34 has a rear side 36. The rear side 36 of the wiper arm linkage element 34 is the side of the wiper arm linkage element 34 which, when correctly installed on a vehicle, is oriented opposite to the forward direction of the vehicle. The two wiper blades 10 are thus connected by the linkage package 14 so that the rear sides 36 coincide.

[0046] While [Fig. 1] shows the system 32 in a state in which the assembly package 14 is partially engaged in the overpack 12, [Fig. 2] shows the assembly package 14 completely outside the overpack 12. The assembly package 14 is designed to be engaged by a form-fit connection in the overpack 12. The assembly package 14 in its folded state has protruding ends 42 of the assembly package 14 to participate in a form-fit connection with the overpack 12. The assembly package 14 in its folded state encloses the wiper arm connecting elements 34 of the wiper blades 10 on three sides. The overpack 12 is made of cardboard; alternatively, the overpack 12 may be made of another raw material. The overpack 12 has a parallelepiped shape. The overpack 12 is intended to package the two wiper blades 10.The wiper blades 10 and the assembly packaging 14 are placed in the opening of the overpack on the front side of the overpack 12. The opening of the overpack includes three closing tabs. The three closing tabs are designed to close the opening of the overpack by a form-fitting connection.

[0047] The assembly package 14 has an outer contour 24 with truncated corner areas 30. The truncated corner areas 30 are formed by fillets. The truncated corner areas 30 are formed, in particular, by material removal, specifically by cutting the corners. In one embodiment, the truncated corner areas 30 can be obtained by folding. The truncated corner areas 30 orient the corner at 45°. In one embodiment, the angles may form a different angle than 45° with respect to the principal extension direction of the assembly package 14. The truncated corner areas 30 are provided to facilitate the assembly of the assembly package 14 into the overpack 12. The truncated corner areas 30 serve as an aid in engaging the assembly package 14 into the overpack 12.

[0048] Figure 3 shows the assembly package 14 in its unfolded state, viewed from above. The assembly package 14 has two parallel folds 16. The parallel folds 16 extend along the entire length 38 of the assembly package 14. The parallel folds result from the formation of the folds in the assembly package 14. The parallel folds 16 can, however, be optically marked. The optical markings of the parallel folds 16 could also be made optically. The optical marking of the parallel folds 16 could indicate a fold. The parallel folds could also be made by a perforation or a perforated fold mark. The folding of the assembly package 14 at the parallel folds 16 forms the protruding corners 42. In the folded state of the assembly package 14, the protruding ends 42 are unfolded by 90° with respect to their main extension plane of the assembly package 14 by the unfolding of the folds.

[0049] The assembly package 14 includes the through recess 18. The assembly package 14 delimits the through recess 18. This through recess 18 is in the middle of the main extension plane of the assembly package 14. The width 44 of the assembly package 14 in the main extension direction of the assembly package 14 is identical on both sides of the through recess 18. The width 46 of the assembly package 14, in the direction perpendicular to the main extension direction of the assembly package 14, is identical on both sides of the through recess 16. The through recess 18 forms a receiving area for the connecting element 20.

[0050] The receiving area 20 of the connecting element is designed to receive two connecting elements of a wiper arm 34. The through recess 18 secures the two connecting elements of the wiper arm 34 in a plane 22 by means of a form connection. The plane 22 is parallel to the main extension plane of the assembly package 14. The assembly package 14 is made of the same material as the overpack 12. The assembly package 14 is made of a material Biodegradable. The biodegradable material is cardboard. However, the biodegradable material could also be paper (in a variant) or cellulose. Wood could also be used. Alternatively, it could be a biodegradable plastic such as PLA.

[0051] The assembly package 14 in its unfolded state has at least one practically rectangular outer contour 24. The through-hole 18 is delimited by a rectangular outer contour 26. The through-hole 18 is parallel to the longitudinal axis 28 of the assembly package 14, limited to a maximum extension of approximately 70%.

[0052] The through-cutout 18 is limited perpendicularly to the longitudinal axis 28 of the assembly package 14 to a maximum extension of approximately 50%. The through-cutout 18 is provided between the two parallel folds 16. The two parallel folds 16 meet the limitation in the longitudinal direction of the through-cutout 18. The parallel folds 16 extend the limitation of the through-cutout 18 in the longitudinal direction through the assembly package 14. The through-cutout 18 directly meets the two parallel folds 16.
