The coupling device of the transversal frame component and the vertical bridge in the handrail

摘要

(57) Abstract Constitution Inside vertical bridge 3 the central axis, namely vertical bridge 3To provide multiple bis pockets 12 on L the diameter belt, vertical bridge 3The end face 3a curved surface condition and the forming which correspond to the peripheral face of transversal frame component 1To do, the curved surface condition end face 3of a vertical bridge 3 peripheral face necessary of transversal frame component 1This touching to the section, from the bis Interpolation through-hole 13 whom it provides in transversal frame component 1Spiral shellfish entrance restraint doing bis 14 in bis pocket 12 of vertical bridge 3ru. Advantages Bis Interpolation through-hole of transversal frame component and bis pocket of vertical bridgeWith hitting against the alignment, profile of the vertical bridge approximately that directIf it should have tried to adjust on the diameter belt to the bis Interpolation through-hole, in additionWhen screwing in bis to the vertical bridge, as for the bis head the water of the side bridge inner skinBecause it means this to touch on plane surface, bis the vertical bridge stands uprightTo be able screw in on the ru vertical line, vis-a-vis the side bridge the vertical bridge the rightCrossing definite, it is possible to concatenate.
