The pivotally collapsible greenhouse 100 (hereinafter invention) is a portable greenhouse that comprising a collapsible frame 101 and a cover 102 and a means to attach the cover 102 on the collapsible frame 101.

The cover 102 comprises sheeting that acts as a barrier that is adapted to protect plants 119 contained within the invention 100 from the surrounding environment. Depending on the needs of the region, the cover 102 can be transparent to allow full sunlight into the greenhouse or it can be tinted to reduce or block the sunlight being received. Materials suitable for use in sheeting include, but are not limited to, commercially available plastic sheeting or textile fabrics.

The purpose of the collapsible frame 101 is to provide a structure upon which the cover 102 can be mounted. This provides a protective physical space 124 within which plants 119 will be protected from the elements.

The collapsible frame 101 comprises a plurality of U shaped posts 120, and a plurality of hinges 121. The plurality of U shaped posts 120 can be further defined as a first U shaped post 103, a second U shaped post 104, a third U shaped post 105, a fourth U shaped post 106, and a fifth U shaped post 107. The plurality of hinges 121 can be further defined as a first hinge 108, a second hinge 109, a third hinge 110, a fourth hinge 111, fifth hinge 112, sixth hinge 113, seventh hinge 114, eighth hinge 115, ninth hinge 116, tenth hinge 117.

Each of the plurality of U shaped posts 120 is made of tubing that is formed roughly in the shape of a flat arch with rounded corners. Each of the plurality of U shaped posts 120 has a first end 171 and a second end 172. Each of the plurality of U shaped posts 120 may be formed as a single piece or may be formed from three straight shafts joined with corner pieces. Each of the plurality of U shaped posts 120 may be made from, but not are not limited to, commercially available aluminum, copper, or polyvinylchloride pipes and fittings.

The length of each of the plurality of U shaped posts 120 is the distance along the tubing from the first end 171 to the second end 172 of each U shaped post 120. The length of the first U shaped post 103 is greater than the length of the second U shaped post 104, which is greater than the length of the third U shaped post 105, which is greater than the length of the fourth U shaped post 106, which is greater than the length of the fifth U shaped post 107. The differences in lengths allow the plurality of U shaped posts 120 to nest within each other as shown in FIG. 3. This allows for easy storage and transportation of the invention 100.

The first end 171 of each of the plurality of U shaped posts 120 is attached to one of the plurality of hinges 121. The second end 172 of each of the plurality of U shaped posts 120 is attached to a corresponding one of the plurality of hinges 121. Methods for attachment include, but are not limited to: 1) screwing the each end of each of the plurality of U shaped posts 120 into a threaded hole provided as part of each of the plurality of hinges 121; or, 2) inserting each end of each of the plurality of U shaped posts 120 into a collar 175 provided with each of the plurality of hinges 121 and then tightening each collar 175 to hold the end of the individual U shaped posts in place.

The purpose of the plurality of hinges 121 is to allow the plurality of U shaped posts 120 to rotate around a first shaft and a second shaft 182. Optionally, governing devices can be incorporated into each of the plurality of hinges 121 to limit the range of motion of each of the plurality of U shaped posts 120 so that each of the plurality of U shaped posts 120 can only move between the storage position and working position.

Each of the plurality of hinges 121 are comprised of a pivoting joint that allows for rotational motion around the first shaft 181 and the second shaft 182. Devices and methods suitable for use in providing the plurality of hinges 121 include, but are not limited to, using a plumbing tee fitting or using commercially available bearings or hinges.

If optional governing devices are used, methods to implement this would include, but are not limited to, selecting a hinge device with a limited range of motion or the addition of protrusions that would act as physical stops once the appropriate range of motion had been achieved.

Once the plurality of U shaped posts 120 are moved in position, they can be held in place by locking the plurality of hinges 121 in place. Methods to do this include, but are not limited to, using the optional governing devices or fitting the plurality of hinges 121 with screws that screw into first shaft 181 and the second shaft 182 to hold the plurality of hinges 121 in place.

The first shaft 181 is a pipe around which half of the plurality of hinges 121 are mounted. The purpose of the first shaft 181 is: 1) to hold the half of the plurality of hinges 121 in position relative to each other; and, 2) to act as a pivot point around which the half of the plurality of hinges 121 will rotate. The first shaft 181 may be made from, but not are not limited to, commercially available aluminum, copper, or polyvinylchloride pipes.

The second shaft 182 is a pipe around which half of the plurality of hinges 121 are mounted. The purpose of the second shaft 182 is: 1) to hold the half of the plurality of hinges 121 in position relative to each other; and, 2) to act as a pivot point around which the half of the plurality of hinges 121 will rotate. The second shaft 182 may be made from, but not are not limited to, commercially available aluminum, copper, or polyvinylchloride pipes.

Several means are available to secure the cover 102 to the collapsible frame 101 including, but not limited to, the following examples. Example 1: if the cover 102 is significantly larger than the collapsible frame 101, the cover 102 can simply be placed over the collapsible frame 101 and held in place using rocks or other weights. Example 2: clips, such as laundry clips or even large binder clips may be used to physically attached cover 102 to the plurality of U shaped posts 120. Example 3: The cover 102 may be formed, sized and fitted to tightly fit over the collapsible frame 101 and the perimeter of the cover 102 can be fitted with elastic webbing to securely hold the cover 102 tightly to the collapsible frame 101.
