Abstract
The present invention discloses a collapsible structure having at least two standing frames connected by an extendable linkage. Each standing frame comprises at least two standing poles. Two standing poles are pivotally connected to each other by a pivot point. The standing frame also includes a linking device that enables two standing poles to be folded or unfolded. The extendable linkage connected to two adjacent standing frames comprises at least one extendable link assembly capable of adjusting the distance of its two ends. The collapsible structure also includes a locking device and telescoping tubes.
Claims20
A collapsible structure, wherein it comprises:
- at least two standing frames connected by an extendable linkage, said extendable linkage allows two adjacent standing frames to be closed or extended;
- and
- each standing frame has two standing poles, comprising a first standing pole and a second standing pole, wherein the top ends of said first and second standing poles are connected by a pivot point, allowing said poles to rotate about said pivot point and to be folded or unfolded;
- and
- whereby, a sliding member slides on said first standing pole, able to move along it's length, and said standing frame also includes a link pole, one end of which is pivotally connected to said sliding member and the other end of which is pivotally connected to said second standing pole;
- when
- said first standing pole is folded towards said second standing pole, said link pole rotates around its second end, and drives said sliding member away from said first pivot point along said first standing pole until both poles are completely folded up;
- and when said first standing pole is opened up from said second standing pole, said link pole rotates accordingly and drives said sliding member towards said first pivot point along said first standing pole until both poles are completely unfolded.
A collapsible structure, wherein it comprises:
- at least a pair of standing frames, each standing frame consisting of two standing poles:
- a first standing pole and a second standing pole, which are pivotally connected at the top through a first pivot point, wherein said first standing pole is pivotally connected with a first bracing pole, and said second standing pole is pivotally connected with a second bracing pole, and the inner ends of said first bracing pole and said second bracing pole are pivotally connected together through a second pivot point;
- and
- an extendable linkage is provided between two adjacent standing frames, allowing them to close or extend, and the first end of said extendable linkage is connected to said first pivot point of one standing frame, and said second end is connected to said first pivot of the other standing frame.
A collapsible structure, wherein it comprises:
- at least two standing frames, each standing frame consisting of two standing poles:
- a first standing pole and a second standing pole, which are pivotally connected at the top through a first pivot point, wherein said first standing pole is pivotally connected with a first bracing pole, and a second standing pole is pivotally connected with said second bracing pole, and the inner ends of said first bracing pole and said second bracing pole are pivotally connected together through a second pivot point;
- and
- an extendable linkage is provided between two adjacent standing frames, allowing them to close or extend, wherein the first end of said extendable linkage is connected to said first and second pivot points of one standing frame, while the second end is connected to said first and second pivot points of another standing frame;
- when
- said extendable linkage folds, it drives said second pivot points away from said first pivot points, causing said bracing poles and said standing poles to rotate and fold accordingly, and when said extendable linkage unfolds, it drives said second pivot points towards said first pivot points, causing said bracing poles and said standing poles to rotate and unfold accordingly.
