Abstract

Oppfinnelsen angår en gravetann (10) for bruk i forskjellige typer graveutstyr, bestående av en spiss (12), en adaptor (14) og en sandwich-låsepinne (16). Pinnen omfatter et stivt hus (54) og et flertall uavhengige nedpressbare fremspring (58, 59). Ett av fremspringene (58) er i elastisk kontakt med en overflate (22) definert på nesen av adapteren, for å stramme tilkoplingen av spissen på nesen. Et annet av fremspringene (59) strekker seg inn i en åpning (50) definert i spissen for å feste låsepinnen til spissen. Når det gjelder en ekstern låsetann, omfatter åpningen (50) i spissen et par knotter (155a, 155b) som definerer et redusert område av åpningen. Det reduserte område mottar og holder endene på det stive hus for låsepinnen. Den uavhengige låsing av pinnen og tilpasset mottaking av huset i åpningen i spissen reduserer sannsyn- ligheten for at pinnen går tapt på grunn av overbelastning av elastomermateri- alet, slitasje av komponentene eller hamrende krefter.The invention relates to a digging tooth (10) for use in various types of digging equipment, comprising a tip (12), an adapter (14) and a sandwich locking pin (16). The pin comprises a rigid housing (54) and a plurality of independent compressible projections (58, 59). One of the projections (58) is in elastic contact with a surface (22) defined on the nose of the adapter, to tighten the connection of the tip to the nose. Another of the projections (59) extends into an opening (50) defined in the tip to secure the locking pin to the tip. In the case of an external locking tooth, the opening (50) at the tip comprises a pair of knobs (155a, 155b) defining a reduced area of the opening. The reduced area receives and holds the ends of the rigid housing of the locking pin. The independent locking of the pin and adapted reception of the housing in the opening at the tip reduces the likelihood of the pin being lost due to overload of the elastomer material, wear of the components or hammering forces.
