Description
La présente invention concerne un balai pour installations d'essuie-glace,The present invention relates to a broom for wiper installations,
pourvu d'un corps de base en matière plastique relativement dure,qui comporte un canal ouvert, ayant une section droite à peu près en forme de T, continu sur son étendue longitudinale et servant à recevoir la zone de pied d'une lame d'essuyage en caoutchouc mou, ayant également une section droite en forme de T et pourvue de protubérances faisant saillie des deux côtés de la tige centrale du "T" et à l'aide desquelles elle s'appuie contre des surfaces de butée du corps de base pendant les mouvements alternatifs de provided with a relatively hard plastic base body, which has an open channel, having a substantially T-shaped cross-section, continuous over its longitudinal extent and serving to receive the foot area of a blade of wiper made of soft rubber, also having a T-shaped cross section and provided with protuberances protruding from both sides of the central stem of the "T" and by means of which it bears against abutment surfaces of the basic body during the alternative movements of
pivotement du balai d'essuie-glace.pivoting of the wiper blade.
Un balai d'essuie-glace de ce genre est déjà A wiper blade of this kind is already
connu d'après la demande de brevet allemand DE-OS 23 44 876. known from the German patent application DE-OS 23 44 876.
La partie d'appui, représentéedanscecas,de la lamine d'essuyage The bearing part, represented in this case, of the wiping lamination
en caoutchouc relativement mou n'est cependant pas suffi- relatively soft rubber is however not enough
sante pour empêcher, dans toutes les conditions de marche, to prevent, under all conditions of operation,
la formation de stries sur la surface de glace à essuyer. the formation of streaks on the ice surface to be wiped.
La présente invention a pour cette raison pour but de perfectionner un balai d'essuie-glace du type précité, de telle sorte que, également dans des conditions défavorables, il se produise un nettoyage correct de la glace. Ce problème est résolu selon l'invention en ce que les surfaces de délimitation du canal s'évasent avec un profil incurvé jusque dans sa zone ouverte d'embouchure et s'épanouissenten formant des parties de pied arrondies, contre lesquelles s'appuient les côtés supérieurs des protubérances, avec conjugaison de formes, alternativement en fonction du sens de pivotement, la forme des surfaces de délimitation du canal et là forme de la lame d'essuyage en caoutchouc étant mutuellement adaptées de telle sorte que la lame d'essuyage en caoutchouc s'applique dans les deux positions de pivotement autant que possible dans une large mesure avec conjugaison de formes contre les The object of the present invention is therefore to improve a windscreen wiper blade of the aforementioned type, so that, also under unfavorable conditions, a proper cleaning of the ice occurs. This problem is solved according to the invention in that the channel delimiting surfaces flare with a curved profile into its open mouth area and open out forming rounded foot portions, against which the sides are supported. upper portions of the protuberances, with a combination of shapes, alternatively depending on the direction of rotation, the shape of the channel delimiting surfaces and the shape of the rubber wiper blade being mutually adapted such that the rubber wiper blade applies in both pivoting positions as much as possible to a large extent with conjugation of forms against
surfaces de délimitation et les parties de pieds. delimitation surfaces and parts of feet.
Selon une particularité avantageuse de l'in- According to an advantageous feature of the invention,
vention, l'appui de la lame d'essuyage en caoutchouc peut encore être amélioré en faisant en sorte que la tige centrale du "T" de la lame d'essuyage en caoutchouc soitdisposée, au moins sur la moitié de sa hauteur, à In addition, the support of the rubber wiper blade can be further improved by ensuring that the central shaft of the "T" of the rubber wiper blade is at least half of its height
