  • Patent number: 7428908
    Abstract: A collapsible canopy frame is provided that includes a first truss bar having a surface that defines an opening; a second truss bar having a surface that defines an opening that is aligned with the first truss bar opening; and a connector assembly that pivotally connects the first truss bar to the second truss bar. The connector assembly includes a locking plate at a second end of the connector assembly having a base that defines first and second surfaces with an opening extending therebetween, wherein the first base surface abuts the second truss bar; and a fastener having a main body that extends through each of the first and second truss bar openings and the locking plate base opening. The fastener also includes spaced apart first and second arms each having a shoulder that laterally extends from the main body to abut the second base surface of the locking plate to pivotally connect the first truss bar to the second truss bar.

  • Patent number: 7395830
    Abstract: A locking pin assembly includes a button that can be moved in a first direction from a first position to a second position, and a first biasing member for biasing the button to be normally in the first position. The locking pin assembly also includes a locking pin member that engages the button and is movable in a second direction, which is substantially perpendicular to the first direction, from a third position to a fourth position when the button is moved from the first position to the second position. The locking pin assembly also includes a second biasing member for biasing the locking pin member to be normally in the third position. The locking pin assembly can be used in a collapsible canopy frame to adjust the height of a telescoping side pole by fixing upper and lower sections to each other and/or to fix the edge scissor assemblies and the side poles in an opened position.

  • Patent number: 7240686
    Abstract: A collapsible canopy frame includes a plurality of side poles, and a plurality of scissor assemblies for coupling the side poles to one another. The collapsible canopy frame also includes a center support pole, which includes an outer pole having an upper end and a lower end, and an inner pole slidable within the outer pole. The inner pole has an upper end that can extend upwardly from the outer pole and a lower end that can extend downwardly from the outer pole. A plurality of center scissor assemblies are provided for coupling the plurality of scissor assemblies to the center support pole. A fixing bracket fixed to the lower end of the outer pole has a central opening around the inner pole and a side opening. A locking pin is disposed at least partly in the side opening of the fixing bracket, and is used for fixedly coupling the inner pole to the fixing bracket.
