Title (EN) SNOW PLOW BLADE ASSEMBLY
(FR) ENSEMBLE LAME DE CHASSE-NEIGE
Abstract:
(EN) A snow plow blade assembly is disclosed that allows substantially rigid blades to shift in response to surfaces and obstacles without placing undue stress on the blade assembly as a whole. The assembly includes a flexible bushing that is received in a bushing hole of a blade, the bushing further having at least one bushing hole to receive at least one stem. The blade is disposed between first and second plates that cooperate with the stem and a fastening means to removably secure all of the elements together. Also disclosed is a kit containing replacement blades and bushings, a flexible bushing or variable density, a wear block assembly on the blade trailing edge, a protuberance on the bushing that is received in one of the plates and a bushing hole formed as two connected lobes for receiving a like shaped bushing.
(FR) L'invention concerne un ensemble lame de chasse-neige qui permet à des lames sensiblement rigides de se déplacer en réponse à des surfaces et des obstacles sans placer une contrainte excessive sur l'ensemble lame dans son ensemble. L'ensemble comprend une bague flexible qui est reçue dans un trou de bague d'une lame, la bague ayant en outre au moins un trou de bague pour recevoir au moins une tige. La lame est disposée entre des première et seconde plaques qui coopèrent avec la tige et un moyen de fixation pour fixer tous les éléments ensemble de manière amovible. L'invention concerne également un kit contenant des lames et des bagues de remplacement, une bague flexible ou une densité variable, un ensemble bloc d'usure sur le bord de fuite de lame, une protubérance sur la bague qui est reçue dans l'une des plaques, et un trou de bague sous forme de deux lobes reliés pour recevoir une bague de forme similaire.
