  • Patent number: 5125613
    Abstract: Display easel having an elongated connector to which are attached three legs which can be moved from parallel storage positions to angular erection positions to form a tripod. The connector has a longitudinal passage in which slides a support rod, the movement of the legs from their storage positions to their erected positions causing the legs to lock the rod at a selected position in the passage. The legs have telescoping extensions and at least one leg has an auxiliary element that is held on the leg by a blind rivet whose head lies in a protuberance in the leg, so that its head does not interfere with sliding of the extension in the leg for adjustment.
