Floor sweeping apparatus (9) of the type having a rotary brush member (20), which in use is driven to rotate about a generally horizontal axis, the brush member (20) having bristle elements (22) that, as the brush member (20) rotates, extend during part of their range of movement through an aperture (13) in a base plate (12) of a housing (10) in which the rotary brush member (20) is rotatably journalled has at least one bristle element (22), hereinafter called an end-most bristle element (25), arranged immediately adjacent to each end of said brush member (20), and a deflector member (26) is provided at each end of the aperture (13) to co-operate with said end-most bristle element (25) at the respective end of the brush member (20). The deflector members (26) deflect said end-most bristle elements (25) axially beyond the end of the aperture (13) as said end-most bristle elements (25) extend through the aperture (13) during the rotation of the brush member (20) to effectively extend the sweeping action at least up to, and preferably beyond, the outer edge of the housing.
La présente invention concerne un appareil (9) permettant de balayer le sol d'un type à brosse (20) rotative, qui en fonctionnement est entraînée de façon à tourner autour d'un axe généralement horizontal. Cette brosse (20) possède des touffes de poils (22) qui, lorsque la brosse (20) tourne, surgissent durant une partie du cycle de leur mouvement à travers une ouverture (13) pratiquée dans la plaque de base (12) d'un boîtier (10) dans lequel cette brosse rotative (20) tourne. Cette brosse possède au moins une touffe de poils (22), appelée touffe de poils d'extrémité (25), agencée à proximité immédiate de chaque extrémité de cette brosse (20), et un élément déflecteur (26) au niveau de chaque extrémité de l'ouverture (13) de façon à coopérer avec ladite touffe de poils d'extrémité (25), à infléchir cette touffe de poils d'extrémité (25) axialement au delà de l'extrémité de l'ouverture (13) pendant la rotation de la brosse (20) et à prolonger efficacement l'action de balayage au moins jusqu'au bord extérieur du boîtier, et de préférence au delà de ce bord.
