  • Patent number: 11255471
    Abstract: A pipe coupling for connecting two pipe ends includes: a clamp band which has a longitudinal slot, an inner housing arranged therein, and a clamping mechanism for reducing the internal diameter of the clamp band. The clamp band is designed as a flat single piece and has an outer band portion and inner band portions which are connected to the outer band portion via at least one connection. A connection assembly is provided for securing the inner housing in the clamp band, where the connection assembly includes a first connection part and a second connection part. The first connection part extends into the second connection part, and at least one of the connection parts of the connection assembly is designed to connect the at least first outer band portion to the at least first inner band portion of the clamp band.

  • Patent number: 10781961
    Abstract: A pipe coupling or a pipe clamp has an outer clamp band with an outer longitudinal slot, an inner clamp band with an inner longitudinal slot and a tensioning mechanism arranged on the outer clamp band. The inner longitudinal slot is offset in relation to the outer longitudinal slot. A separate flat spanning element is provided on the inner clamp band in order to span the inner longitudinal slot. The spanning element extends from one side of the inner longitudinal slot towards the other side of said longitudinal slot.

  • Publication number: 20160109051
    Abstract: The invention relates a tensioning or pipe clamp with a housing (22) comprising a longitudinal slot (23), wherein the regions of the housing (22) lying opposite one another at the longitudinal slot (23) are constituted as bent brackets (24, 26), and with a tensioning mechanism (32) for tightening the housing (22). The tensioning mechanism (32) comprises a first bolt (33) and a second bolt (35), which are each provided in the brackets (24, 26), and a tensioning means (36) which is held in the first bolt (33) and can be swivelled relative to the second bolt (35). The tensioning mechanism (32) also comprises a distance part (42), which comprises a contact section (43) which can be brought into contact with a contact region (40) of the second bolt (35), and a feed-through opening (46) for the tensioning means (36), said feed-through opening being spaced apart from the contact section (43) of the distance part (42).

  • Patent number: 7648107
    Abstract: Brace or pipe clamp with a deformable, essentially cylindrical housing, which has at least one longitudinal slot. The regions of the housing that are situated opposite one another at the longitudinal slot are formed as bent over lugs. The lugs are used to accommodate hollow bolts. The housing can be braced by means of clamping bolts, which penetrate the hollow bolts transversely and are arranged approximately tangentially to the housing, and nuts which can be connected to said clamping bolts. At least one of the clamping bolts is connected directly or indirectly with a handle for manually pretensioning the brace or pipe clamp and/or for operating the clamping bolt.
