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.
Claims16
A collapsible structure comprising:
- at least two standing frames connected by an extendable linkage, said extendable linkage allows the at least two standing frames to be closed or extended;
- wherein each of said at least two standing frames has;
- two standing poles, comprising a first standing pole and a second standing pole, wherein a top end of said first standing pole and a top end of said second standing pole are connected by a pivot point, allowing said two standing poles to rotate about said pivot point and to be folded or unfolded;
- a sliding member mounted to the first standing pole and configured to slide on said first standing pole, able to move along a length thereof;
- and
- a link pole, one end of which is pivotally connected to said sliding member and a second end thereof is pivotally connected to said second standing pole;
- wherein each of said at least two standing frames is configured such that when said first standing pole of the respective standing frame is folded towards said second standing pole of the respective standing frame, said link pole of the respective standing frame rotates around the second end thereof, and drives said sliding member of the respective standing frame away from said pivot point of the respective standing frame along said first standing pole of the respective standing frame until the two standing poles of the respective standing frame are completely folded up;
- and when said first standing pole of the respective standing frame is opened up from said second standing pole of the respective standing frame, said link pole of the respective standing frame rotates accordingly and drives said sliding member of the respective standing frame towards said pivot point of the respective standing frame along said first standing pole of the respective standing frame until the two standing poles of the respective standing frame are completely unfolded.

A collapsible structure comprising:
- 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 a top through a first pivot point, wherein said first standing pole is pivotally connected with a first bracing pole, and the second standing pole is pivotally connected with a second bracing pole, and inner ends of said first bracing pole and said second bracing pole are pivotally connected together through a second pivot point;
- wherein for each standing frame:
- said first standing pole includes a sliding member, said second standing pole includes a sliding member;
- said first bracing pole is pivotally connected to the sliding member of the first standing pole;
- and said second bracing pole is pivotally connected to the sliding member of the second standing pole;
- and
- an extendable linkage is provided between the at least two standing frames, to provide for closure or extension, wherein a first end of said extendable linkage is connected to said first pivot point and said second pivot point of a first standing frame of the at least two standing frames, a second end of said extendable linkage is connected to said first pivot point and said second pivot point of a second standing frame of the at least two standing frames;
- said extendable linkage is folded, for:
- each standing frame of the at least two standing frames is configured such that when said extendable linkage drives said second pivot point of the respective standing frame away from said first pivot point of the respective standing frame, causing said bracing poles of the respective standing frame and said standing poles of the respective standing frame to rotate and fold accordingly, and when said extendable linkage is unfolded, said extendable linkage drives said second pivot point of the respective standing frame towards said first pivot point of the respective standing frame, causing said bracing poles of the respective standing frame and said standing poles of the respective standing frame to rotate and unfold accordingly.
