  • Patent number: 10676957
    Abstract: A tent system including: a fabric member including a body portion and a bottom portion to form a resident space; a fixing device disposed at the fabric member and including a mesh pocket, an upper clip, a lower clip and a side clip; a main pole coupled to the fabric member in an X-shape through the fixing device, in which one end and an opposite end of the main pole are supported by the mesh pocket and the lower clip, respectively; and an adjusting device that allows at least one of the fixing device and the main pole to have a variable structure. The tent is easily installed and disassembled even by one person with a simple structure and maintains a tight supported state to the ground, so that usability is improved in cost-effectiveness.

  • Patent number: 8776815
    Abstract: A collapsible shelter assembly includes legs, a truss system, a cover, cover supporting rods and mounting brackets. Each of the legs has an upper and a lower end. The truss system is configured to link each pair of legs together and define a base perimeter. The brackets are adapted for mounting to the upper ends of the legs, for attaching to the rods at a predefined distance distal to ends of the rods and for defining an outer perimeter greater than the base perimeter. The cover is adapted for attaching about the ends of the rods for covering the outer perimeter.

  • Patent number: 8215326
    Abstract: A collapsible shelter assembly includes plurality of legs with each of the legs having an upper, a lower end and an axis. A truss system links each pair of legs together and defines a perimeter. Rods are adapted for supporting a cover and brackets are adapted for attaching the rods to the legs. Each of the brackets has a base adapted for attachment to the upper end one of the legs and a coupler mounted to the base for attaching one of the rods. Each bracket is configured so that at least one of the base and the coupler is rotatable relative to the leg axis.
