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 the wiper blade and/or of the longitudinal strip may be connected, if desired, with a respective connecting piece, the 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. The longitudinal strip is usually referred to as a flexor, whereas the connecting piece is usually indicated as an end cap. The connecting device in practice is referred to as a connector. The 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, the carrier may also comprise two longitudinal strips, wherein the strips are disposed in opposite longitudinal grooves of the wiper blade. The 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 the shaft is rotatable alternately in a clockwise and in a counter-clockwise sense carrying the mounting head into rotation. Thus, in turn the mounting head draws the connecting device into rotation and thereby moves the wiper blade. In the alternative, the mounting head is fixed for translation to a carriage, wherein the carriage can be translated alternately in a one linear direction and in another counter linear direction carrying the mounting head into translation. The present windscreen wiper device can therefore be used for circular or linear movement of the 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 the package, whereas once the windscreen wiper device is taken out the 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 the package has a quadrangular cross-section having four walls enclosing four vertices (also referred to as corners), wherein the package has an internal partition wall extending along the length of the package, wherein the partition wall forms inside the 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 the 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 the 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 the triangular chambers each have at least one vertex with an acute angle preferably equal to or smaller than 45°, the windscreen wiper devices are supported inside the chambers at the location of their connecting devices and/or the connecting pieces, for example, without damaging a longitudinal wiping lip of the wiper blade thereof. Thus, the 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, the partition all extends along the entire length of the 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 the partition wall encloses an acute angle equal to or smaller than 45° with an adjacent wall of the four walls of the quadrangular cross-section of the package. Particularly, the partition wall encloses an acute angle smaller than 40°, preferably smaller than 35°, more preferably smaller than 30° with an adjacent wall of the four walls of the quadrangular cross-section of the package.
In another preferred embodiment of an elongated package according to the invention the partition wall extends between opposite vertices of the quadrangular cross-section of the package.
In another preferred embodiment of an elongated package in accordance with the invention the package has a rectangular cross-section. In the alternative, the package has a rhombic cross-section or a trapezoidal cross-section.
In another preferred embodiment of an elongated package according to the invention the package and the partition wall are made in one piece of material. In the alternative, the partition wall is a separate constructional element. In the latter case the partition wall may then be slid inside the package. Preferably, the package and the 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 the chambers, and wherein the other windscreen wiper device thereof is held by the other of the chambers. Particularly, a wiping lip of each windscreen wiper device of the flat blade type is facing towards the acute angle.
The invention will now be explained in more detail with reference to figures illustrated in a drawing, wherein:
With reference to
