The bracket 11, Fig. 2, on door 10 is formed with two such rollers 25 running in track rails 28 secured to the wall and so arranged that one roller contacts the upper flange 30 of the rails and the other roller contacts the lower flange 27 of the rails, the tyres on the rollers being in compression. A tie bar 31 may secure together two such brackets on one door. The tyres may be so shaped as to be " selfaligning " in the rails. |
