H-profile rail fits into a C-section mounting whose lower arm fits into groove in its lower arm and whose upper arm has resilient lug fitting into groove in its upper arm

摘要

The H-profile rail (100) fits into a C-section mounting (112). The lower arm (118) of this has a hook (128) at the end which fits into a groove (106) on the inner side of the lower arm of the H-profile. A resilient lug (120) on the underside of the upper arm of the C-profile fits into a second groove (108) on the inner side of the upper arm of the H-profile. An independent claim is included for blinds supported at the top by the rails.
