Abstract
A wall element incorporating idle rollers, presenting a body with seats into which stationary pins carrying idle rollers are snap-fitted; said body presents two parts (22, 30), of which one is the lower base part (22) and the other the upper base part (30), these being structurally separate, but connected together by just the pins (10, 21), which present end portions (15, 15A) transversely wider than adjacent portions (11a, 21a) provided for their snap-fitting into seats (12a,b,c; 22a,b,c) in said two parts (22, 30), said wider portions (15, 15A) abutting against said seats to prevent any movement of said parts (22, 30) in the axial direction of the pins (10, 21).
Claims6
A wall element incorporating idle rollers comprising:
- a body with seats into which stationary pins carrying idle rollers are snap-fitted, said body having two parts (22, 30), of which one is a lower base part and the other an upper base part, these being structurally separate, but connected together by just the pins (10, 21), which present end portions (15, 15A) transversely wider than adjacent portions (11a, 21a) provided for their snap-fitting into seats (12a,b,c;
- 22a,b,c) in said two parts (22, 30), said wider portions (15, 15A) abutting against said seats to prevent any movement of said parts (22, 30) in the axial direction of the pins (10, 21).
A wall element incorporating idle rollers, comprising:
- a body including a lower base part defining a lower slot and an upper base part defining an upper slot;
- a plurality of pins disposed between said lower base part and said upper base part, each of said plurality of pins includes a first end portion, second end portion, a first narrow portion, a second narrow portion and a center portion wherein said first and second end portions have a diameter greater than said narrow portion and wherein said center portion has a diameter greater than said narrow portion;
- and
- wherein said lower slot receives said first narrow portion and said upper slot receives said upper narrow portion, said first end portion being in abutment with said lower base portion and said second end portion being in abutment with said upper base portion whereby each of said end portions of said plurality of pins prevents movement of said lower base part and said upper base part in the axial direction of said plurality of pins.
