  • Patent number: 5490350
    Abstract: A Christmas-tree stand (2) essentially consists of a housing (6) in which two clamping bars (18, 20) are rotatably supported so as to allow a swivelling movement around two support pins (22, 24). The activation of the clamping straps (18, 20) takes place via a central clamping device which essentially consists of a threaded rod (26) with two inversely threaded sections (32, 34) constructed thereon. When rotating the threaded rod (26), the free ends of the clamping bars (18, 20) are moved along by the nuts (30, 30') running along with the threaded sections (32, 34), so that a Christmas-tree trunk can be fixed or fastened between the clamping bars (18, 20).
