System of differently designed swivel castors as well as a castor designed as a swivel castor

摘要

The invention relates to a system (S) of differently designed castors (1, 101, 201, 301), each of which has a running wheel (2, 102, 202, 302), a steering axis (x) that is vertically aligned in the installed state and one in an upper one Have sliding or roller bearings (8) received mounting pins (5) and side panels (23) for the wheel, the castors differing in terms of the diameter of the wheel and / or the design of the wheel itself and / or the cover. In order to improve a system of the type in question, it is proposed that all swivel castors belonging to the system have the same design and dimensions with regard to the upper sliding or roller bearing (8) and its mounting in the swivel castor, with two fork halves (3, 4) are provided which, in the installed state, form bearing shell halves (6, 7) on the top, each with a receiving area, the receiving areas together forming the seat in which bearing shell halves the upper sliding or roller bearing for the fastening pin can be received and a dimensional design of the seat together with the same plain and roller bearing, results in an identical design of all swivel castors of the system (S) in terms of strength, with the fork halves also forming a pin and a pin receptacle on the underside to accommodate a lower slide or roller bearing (17) for the impeller, the dimensional design of the pin and the pin receptacle m With the same sliding and roller bearing, all swivel castors of the system (S) have the same design in terms of strength, the fork halves being designed as injection-molded plastic parts.
