A portal covering such as a door (12) or window having a handle (14) that rotates as the door (12) or window rotates. The handle (14) is rotatably mounted within the portal covering. The handle (14) is coupled to a shaft (16) that is coupled to the portal covering via couplings (18). On an end of the shaft is a gear (20) that meshes with an adjacent gear (22). The adjacent bevel gear (22) is coupled to a second shaft (24) extending on a different axis from the first shaft (16). There is also a second, oppositely spaced bevel gear (28) positioned on the second shaft (24) opposite the first bevel gear (22). The second bevel gear (28) on the second shaft (24) couples with a fixed bevel gear (30) that is fixed to a door frame (34) or a window frame. As the covering (12) rotates with respect to the frame (34), the handle (14) rotates with the covering rotation allowing the user to always have contact with the handle (14) at all angles of rotation of the covering (12).

L'invention se rapporte à un couvercle de portail tel qu'une porte ou une fenêtre dotée d'une poignée qui pivote au moment où la porte ou la fenêtre pivotent. En principe, ce couvercle de portail comporte une poignée installée rotative à l'intérieur du couvercle de portail. Cette poignée est couplée à un arbre qui est relié au couvercle de portail au moyen d'éléments de couplage. Un engrenage est installé sur une extrémité de l'arbre et vient en prise avec un engrenage adjacent. Un engrenage conique adjacent est couplé à un arbre qui s'étend sur un axe différent du premier arbre. Un deuxième engrenage conique espacé dans le sens opposé est installé sur ce second arbre à l'opposé du premier engrenage conique. Le second engrenage conique situé sur le second arbre est couplé à un engrenage conique fixe qui est fixé de manière à recouvrir un cadre tel qu'une encadrement de porte ou de fenêtre. Lorsque le couvercle pivote à l'intérieur du cadre, la poignée pivote, cette rotation du couvercle permettant à l'utilisateur de rester toujours en contact avec la poignée au niveau de tous les angles de rotation du couvercle.
