BACKGROUND OF THE INVENTION
The present invention relates to the field of buildings including tents and canopies, more specifically, a tent with a flexible and foldable frame.
The convenience and simplicity of pop-up tents make them popular for use in outdoor environments. When extended, a pop-up tent forms a characteristic dome shape that has a low vertical span relative to the volume of interior space enclosed within the pop-up tent. While this is appropriate for most purposes, when the pop-up tent is used for activities requiring a person to stand upright, such as changing clothes, a pop-up tent can take up a lot of area relative to the requirements of the activity. Clearly a pop-up tent type structure that forms cylindrical or rectangular block interior spaces would be of benefit for such situations.
SUMMARY OF INVENTION
The present disclosure addresses the problem with pop-up tents described above.
The portable pop-up tent comprises a cover, a self-supporting frame, and a retaining strap. The portable pop-up tent is a self-erecting structure that is used to create a private space within a public setting. The self-supporting frame is a spring-loaded structure. The springs within the spring-loaded structure are arranged such that the springs will cause the self-supporting frame to extend into a rectangular block shape without intervention from a person 196. The covering encloses the self-supporting frame for the purpose of creating the private space. The retaining strap holds the self-supporting frame and the cover in position when the self-supporting frame is placed in a collapsed position.
These together with additional objects, features and advantages of the portable pop-up tent will be readily apparent to those of ordinary skill in the art upon reading the following detailed description of the presently preferred, but nonetheless illustrative, embodiments when taken in conjunction with the accompanying drawings.
In this respect, before explaining the current embodiments of the portable pop-up tent in detail, it is to be understood that the portable pop-up tent is not limited in its applications to the details of construction and arrangements of the components set forth in the following description or illustration. Those skilled in the art will appreciate that the concept of this disclosure may be readily utilized as a basis for the design of other structures, methods, and systems for carrying out the several purposes of the portable pop-up tent.

The portable pop-up tent 100 (hereinafter invention) comprises a cover 101, a self-supporting frame 102, and a retaining strap 103. The invention 100 is a self-erecting structure that is used to create a private space within a public setting. The self-supporting frame 102 is a spring-loaded structure. The springs within the spring-loaded structure are arranged such that the springs will cause the self-supporting frame 102 to extend into a rectangular block shape without intervention from a person 196. The cover 101 encloses the self-supporting frame 102 for the purpose of creating the private space. The retaining strap 103 holds the self-supporting frame 102 and the cover 101 in position when the self-supporting frame 102 is placed in a collapsed position.
The self-supporting frame 102 is a collapsible structure that supports the cover 101. In the first potential embodiment of the disclosure, the self-supporting frame 102 forms a rectangular block structure. The self-supporting frame 102 comprises a plurality of struts 111 and a plurality of springs 112. The plurality of springs 112 are stored in a tension bearing state while the self-supporting frame 102 is in a collapsed state. This configuration allows the invention 100 to use the energy stored within each of the plurality of springs 112 to expand the self-supporting frame 102.
Each of the plurality of struts 111 is a structural member that is used to form the self-supporting frame 102. The plurality of struts 111 comprises a first strut 151, a second strut 152, a third strut 153, a fourth strut 154, a fifth strut 155, a sixth strut 156, a seventh strut 157, and an eighth strut 158. The first strut 151 is further defined with a first end 171 and a second end 172. The second strut 152 is further defined with a third end 173 and a fourth end 174.

The first strut 151 is a U shaped strut 191. The second strut 152 is a U shaped strut 191. The third strut 153 is a straight strut 192. The fourth strut 154 is a straight strut 192. The fifth strut 155 is a U shaped strut 191. The sixth strut 156 is a straight strut 192. The seventh strut 157 is a straight strut 192. The eighth strut 158 is a U shaped strut 191.
Each of the plurality of springs 112 is a readily and commercially available torsion spring. Each of the plurality of springs 112 are used to attach each of the plurality of struts 111 to each other. Each of the plurality of springs 112 are installed such that each of the plurality of springs 112 is under tension when the self-supporting frame 102 is in the collapsed state. Each of the plurality of springs 112 are installed such that each of the plurality of springs 112 is in the relaxed shape when the self-supporting frame 102 is in the extended state. The plurality of springs 112 comprises a first torsion spring 161, a second torsion spring 162, a third torsion spring 163, a fourth torsion spring 164, a fifth torsion spring 165, a sixth torsion spring 166, a seventh torsion spring 167, an eighth torsion spring 168, a ninth torsion spring 169, and a tenth torsion spring 170.
As shown most clearly in FIG. 5, the assembly of the self-supporting frame 102 is described in this paragraph. The first torsion spring 161 attaches the first end 171 of the first strut 151 to the third end 173 of the second strut 152. The second torsion spring 162 attaches the second end 172 of the first strut 151 to the fourth end 174 of the second strut 152. The third torsion spring 163 attaches the fifth end 175 of the third strut 153 to the shaft of the of the second strut 152 that is attached to the distal end relative to the fifth end 175 of the third strut 153.
