  • Patent number: 6550733
    Abstract: A support for a window screening device includes a first pair of bracket members (6) for mounting on each of a pair of opposed parallel frame surfaces (2) engageable by the screening device. Each bracket member includes a relatively flat front part protruding from the frame surface and having a substantially smooth external surface, and the engaging mechanism (11-12; 111-112; 33-34) is provided by each coupling member (7; 107; 207; 307; 36) and includes a first engaging mechanism in the form of at least one contact surface on the coupling member engaging a circumferential surface part of a bracket member to provide temporary engagement therewith and non-resilient second engaging mechanism providing stable engagement of the coupling member with respect to the frame structure.

  • Patent number: 6283427
    Abstract: A supporting mechanism for a window screening device comprises a first pair of bracket members for mounting on each of a pair of opposed parallel frame surfaces of the frame structure and a second pair of coupling members engageable by the screening device. Each bracket member and each coupling member comprises an engaging mechanism for releasable sliding engagement of a coupling member with a bracket member. Each bracket member or each coupling member is provided with a resilient mechanism engageable with an abutment of a coupling member or a bracket member to retain the bracket member and the coupling member in mutual engagement. The bracket members are identical standard members each comprising a relatively flat front part protruding from said frame surface and having a substantially smooth external surface and engaging mechanism formed by a pair of opposed parallel side edges.
