Definitions

  • the present disclosure generally relates to the attachment of pivoting structural members in an integrated collapsible canopy system. Specifically, the present disclosure relates to a structural device, in the form of non-compressible mounting brackets each forming a plurality of sockets for use in a collapsible canopy framework, wherein each socket captures an end portion of a scissor assembly member. [0003] 2. General Background
  • a collapsible frame adapted to support a flexible fabric canopy or tent in an extended configuration and a collapsed configuration in accordance with the present disclosure has a plurality of upright support members oriented alongside one another in the collapsed state and movable outwardly apart from one another toward the expanded state.
  • a plurality of edge scissor link assemblies each interconnect adjacent support members, each edge scissor link assembly comprising one or more pairs of scissor link members.
  • a unique mounting bracket connects one or more scissor link members to one of either one of the upright support members or another edge scissor link assembly.
  • the mounting bracket is a solid body having a plurality of sockets therein each shaped to receive and pivotally hold one end of one of the link members therein.
  • Each socket has an inner face, a horizontal wall, and only a single vertical side wall merging substantially at a right angle with the horizontal wall and the inner face of the socket.
  • a pivot fastener extends through the one end of the link member and into the single side wall to hold the member in the socket and permit rotation of the link member about an axis of the pivot fastener.
  • the mounting bracket further includes means formed between the horizontal wall of the socket and the end of the link member in the socket for limiting the effect of twisting side stresses applied to the scissor link member in the socket when the frame is fully expanded to support the canopy or tent cover.
  • the means for limiting preferably is formed within the socket by a groove formed in the horizontal wall extending parallel to the vertical wall and mates with a complementary shaped rib formed on the end of the scissor member engaged with the groove in the socket when the pivot fastener fastens the link member to the vertical wall in the socket.
  • the means for limiting may preferably be a rib formed in the horizontal wall extending into the socket parallel to the vertical wall and a complementary shaped groove formed on the end of the scissor member engaged with the rib in the socket when the pivot fastener fastens the link member to the vertical wall in the socket.
  • the framework structure includes several different configurations of the mounting bracket of the present disclosure that have two, three, or four or more sockets formed therein, each of which includes the means for limiting the effect of twist or side stresses to which the scissor member in the socket may be subjected to.
  • a mounting bracket at one of the corners of the framework may have two sockets at right angles.
  • a mounting bracket placed in the center of the framework for supporting the central portion of the canopy roof will have four sockets at right angles from each other. If the canopy or tent framework has roof members extending from the corners, then the corner mounting brackets each may include a socket oriented between the right angle sockets.
  • the framework structure can be folded and stored in a collapsed state and erected in an expanded state on a support surface in order to support a canopy covering above the support surface. In the collapsed state, the support members are oriented alongside one another but are movable outwardly apart from one another towards the expanded state.
  • a preferred embodiment of the framework structure includes a plurality of edge scissor assemblies that form truss members for the expandable framework with there being an edge scissor assembly interconnecting adjacent ones of the support members. Each edge scissor assembly may be made of two or more pairs of scissor members linked together.
  • mounting brackets in accordance with the present disclosure connecting the scissor member pairs together.
  • a fixed and slidable pair of mounting brackets are disposed on the upright support members to fasten the edge scissor assemblies to the upright support members.
  • the mounting brackets each have sockets that include a track or means for engaging the end of the scissor member of the scissor assembly received within a respective one of the sockets.
  • a fastening pivot pin pivotally secures each outer end portion of each edge scissor assembly in its respective socket.
  • the mounting brackets on the upright support member are relatively movable with respect to one another so that the edge scissor assemblies are operative to open and close whereby the framework structure may move between the expanded and contracted states.
  • One mounting bracket is stationary while the other is slidable.
  • the sockets and the mounting brackets thus provide pivotal connections for the scissor bars or members which form the scissor pairs which in turn comprise the scissor assemblies.
  • the roof support assembly of the framework may be extendible roof members pivotally attached to the stationary mounting brackets in sockets at upper ends of the upright support members with these roof members projecting radially inwardly to form one or more apices to support the canopy covering. Alternately, the roof support members may extend radially inwardly from the slide mounting brackets to form such apex.

Abstract

La structure selon l'invention est pliable et extensible pour supporter un abri en toile lorsqu'un revêtement est placé au sommet de la structure, et comprend une pluralité de supports verticaux et une pluralité d'assemblages en ciseaux de bord qui relient entre eux les supports verticaux qui sont adjacents. Des supports de fixation sont disposés sur les supports verticaux et également entre les assemblages en ciseaux pour fixer les parties d'extrémité externes des assemblages en ciseaux de bord entre elles ou sur les supports verticaux. Les supports de fixation présentent chacun une pluralité de prises de parois latérales uniques comprenant chacune un moyen de limitation de la torsion des assemblages en ciseaux fixés dans la prise. Les moyens de limitation comprennent une rainure ou nervure complémentaire pour mettre en prise mutuellement, de manière complémentaire, une nervure ou rainure complémentaire, respectivement, formée sur l'extrémité de l'élément en ciseaux reçue dans la prise et fixée à l'intérieur de celle-ci avec un axe d'articulation. Les supports de fixation sur chaque support vertical peuvent être relativement mobiles pour permettre l'extension et la contraction de la structure tout en limitant les contraintes côte à côte sur les éléments en ciseaux maintenus de manière pivotante à l'intérieur des supports de fixation.
