Description:
AN ELONGATED PACKAGE FOR A WINDSCREEN WIPER DEVICE OF THE FLAT BLADE TYPE

The present invention relates to an elongated package for a windscreen wiper device of the flat blade type.

The present invention also relates to a system comprising such an elongated package according to the invention, as well as two windscreen wiper devices of the flat blade type packaged therein. A windscreen wiper device of the flat blade type comprises an elastic, elongated carrier element, as well as an elongated wiper blade of a flexible material, which can be placed in abutment with a windscreen to be wiped, which wiper blade includes at least one longitudinal groove, in which groove a longitudinal strip of the carrier element is disposed, wherein ends of said wiper blade and/or of said longitudinal strip may be connected, if desired, with a respective connecting piece, said carrier element biasing the wiper blade in a curved position, which windscreen wiper device comprises a connecting device for pivotally connecting an oscillating wiper arm thereto near one end thereof. Said longitudinal strip is usually referred to as a flexor, whereas said connecting piece is usually indicated as an end cap. Said connecting device in practice is referred to as a connector. Said wiper blade is preferably made by extrusion. Hence, the present windscreen wiper device is designed as a so-called "yokeless" wiper device, wherein use is no longer made of several yokes pivotally connected to each other, but wherein the wiper blade is biased by the carrier element, as a result of which it exhibits a specific curvature.

It is noted that the present invention is not restricted to the use of only one longitudinal strip forming the elastic carrier that is particularly located in a central longitudinal groove of the wiper blade. Instead, said carrier may also comprise two longitudinal strips, wherein said strips are disposed in opposite longitudinal grooves of the wiper blade. Said groove(s) may be closed at one outer end. Further, it is noted that in practice use is made of a mounting head fixed for rotation to a shaft, wherein said shaft is rotatable alternately in a clockwise and in a counter-clockwise sense carrying said mounting head into rotation. Thus, in turn said mounting head draws said connecting device into rotation and thereby moves said wiper blade. In the alternative, said mounting head is fixed for translation to a carriage, wherein said carriage can be translated alternately in a one linear direction and in another counter linear direction carrying said mounting head into translation. The present windscreen wiper device can therefore be used for circular or linear movement of said mounting head.

Such an elongated package is generally known.

One drawback of this known package is the fact that due its specific curvature the windscreen wiper device thereof cannot be inserted easily in said package, whereas once said windscreen wiper device is taken out said package it cannot be handled easily, for example in an outlet for display purposes. A further disadvantage is that it is expensive and cumbersome to make use of two packages for packaging two windscreen wiper devices with wiper blades having different lengths for a car.

The object of the invention is to overcome the drawbacks of the prior art as mentioned above, in particular to make it possible that the windscreen wiper device can be efficiently held during transport, storage and display.

In order to accomplish that objective, an elongated package of the kind referred to in the introduction is characterized according to the invention in that said package has a quadrangular cross-section having four walls enclosing four vertices (also referred to as corners), wherein said package has an internal partition wall extending along the length of the package, wherein said partition wall forms inside said package two chambers having along their length an at least substantially triangular cross-section, wherein each chamber is arranged to hold a windscreen wiper device of the flat blade type, and wherein at least one vertex of said triangular chambers has an acute angle. Thus, this package is shaped such that a windscreen wiper device of the flat blade packed therein is supported along its connecting device and/or its longitudinal strips and/or its connecting pieces, while a wiping lip thereof rests free inside towards a vertex of the respective chamber (i.e. is not engaged by the walls of the respective chamber). The present package allows packaging two windscreen wiper devices in said chambers, so that particularly two windscreen wiper devices with wiper blades having different lengths for one car can be efficiently transported, stored and displayed in one package. Further, as said triangular chambers each have at least one vertex with an acute angle preferably equal to or smaller than 45°, said windscreen wiper devices are supported inside said chambers at the location of their connecting devices and/or said connecting pieces, for example, without damaging a longitudinal wiping lip of the wiper blade thereof. Thus, said wiping lip is not engaged by the package and rests free inside the package. Wiping properties are therefore not negatively affected by using the package for transport, storage and display. Particularly, said partition all extends along the entire length of said package.

It is noted that the present elongated package enveloping the two windscreen wiper devices is used without any further packages, so that the present package solely acts as holder during transport, storage and/or display.

In one preferred embodiment of an elongated package in accordance with the invention said partition wall encloses an acute angle equal to or smaller than 45° with an adjacent wall of said four walls of said quadrangular cross-section of said package. Particularly, said partition wall encloses an acute angle smaller than 40°, preferably smaller than 35°, more preferably smaller than 30° with an adjacent wall of said four walls of said quadrangular cross-section of said package.

In another preferred embodiment of an elongated package according to the invention said partition wall extends between opposite vertices of said quadrangular cross-section of said package.

In another preferred embodiment of an elongated package in accordance with the invention said package has a rectangular cross-section. In the alternative, said package has a rhombic cross- section or a trapezoidal cross-section.

In another preferred embodiment of an elongated package according to the invention said package and said partition wall are made in one piece of material. In the alternative, said partition wall is a separate constructional element. In the latter case the partition wall may then be slid inside said package. Preferably, said package and said partition wall are both made of a cellulose containing material, preferably cardboard.

As indicated, the present invention also refers to a system comprising an elongated package according to the present invention, as well as two windscreen wiper devices of the flat blade type, wherein one windscreen wiper device thereof is held by one of said chambers, and wherein the other windscreen wiper device thereof is held by the other of said chambers. Particularly, a wiping lip of each windscreen wiper device of the flat blade type is facing towards said acute angle.

The invention will now be explained in more detail with reference to figures illustrated in a drawing, wherein: figure 1 is a total perspective, schematic view of a windscreen wiper device of the flat blade type to be packaged in a package according to the invention; figure 2 is a perspective, schematic view of a preferred embodiment of a box-like package in accordance with the invention, together with two windscreen wiper devices of the flat blade type ready to be packaged; figure 3 corresponds to figure 2, but now sliding said windscreen wiper devices inside said package; figure 4 corresponds to figure 3, but now said windscreen wiper devices being packaged (only one is visible); and figure 5 is a schematic side view of the package of figure 4 showing that the packaged windscreen wiper devices are straightened inside the package.

Figure 1 shows a preferred variant of a windscreen wiper device 1 of the flat blade type. Said windscreen wiper device is built up of an elastomeric wiper blade 2, in the longitudinal sides of which opposing longitudinal grooves 3 are formed, and of longitudinal strips 4 made of spring band steel, which are fitted in said longitudinal grooves 3. Said strips 4 form a flexible carrier element for the rubber wiper blade 2, as it were, which is thus biased in a curved position (the curvature in operative position being that of a windscreen to be wiped). Neighboring ends 5 of strips 4 are interconnected on either side of the windscreen wiper device 1 by means of connecting pieces 6 or end caps functioning as clamping members. In this embodiment, the connecting pieces 6 are separate constructional elements, which may be form-locked as well as force-locked to the ends 5 of strips 4. In another preferred variant, said connecting pieces 6 are in one piece with the strips 4 made of spring band steel. In the latter case said connecting pieces form transverse bridges for the strips 4, as it were. The windscreen wiper device 1 is furthermore built up of a connecting device 7 of plastic or metallic material for an oscillating wiper arm 8. Connecting device 7 comprises clamping members 9 that are integral therewith, which engage round longitudinal sides of the strips 4 that face away from each other, as a result of which the connecting device 7 is firmly attached to the unit consisting of wiper blade 2 and strips 4. The oscillating wiper arm 8 is pivotally connected to the connecting device 7 about a pivot axis near one end. A spoiler or "air deflector" 10 is included and comprises two separate sub-spoilers 11. Each sub-spoiler 11 is detachably connected in its entirety to the wiper blade 2 on opposite sides of the connecting device 7. In figure 2 an elongated box-like package 12 having a rectangular cross-section is depicted. The package 12 is made from one blank and is made entirely of cardboard. As shown, the package 12 has a partition wall 13 in one piece thereof. The partition wall 13 extends along the entire length of the package 12 and between opposite vertices 14,15 of said package 12. This partition wall 13 divides the internal space inside said package 12 into two chambers 16,17 having a triangular cross-section along their entire length. Each chamber 16,17 is arranged to receive and

accommodate a windscreen wiper device 18,19 of the fiat blade type. This is shown in figure 3, wherein these windscreen wiper devices 18,19 are slid in longitudinal direction inside their corresponding chambers 16,17.

With reference to figure 4, said partition wall 13 encloses an acute angle a smaller than 45° with an adjacent wall 20 of said box-like package 12, so that the windscreen wiper device 19 shown is supported inside its corresponding chamber 17 at the location of its connecting device 7 and/or its connecting pieces 6, and so that a wiping lip 21 of the wiper blade 2 thereof is not engaged at all. The wiping lip 21 rests thus free inside the chamber 17 and cannot be damaged during transport, for example. The other windscreen wiper device 18 (not shown) would be inside its corresponding chamber 16 in a position upside down compared to the windscreen wiper device 19, as depicted in figure 3.

As shown in figure 5, the windscreen wiper devices 18,19 are stretched, i.e. straightened inside their corresponding chambers 16,17, seen relative to their curved position prior to insertion in the package in figure 2 (shown in dotted lined in figure 5).

The present invention is not restricted to the embodiment shown, but also covers other preferred embodiments falling under the scope of the appended claims.
