Description
- This is a continuation-in-part application of U.S. patent application Ser. No. 17/980,457, filed Nov. 3, 2022, which is incorporated herein by reference in its entirety.
- The present invention generally relates to a sidewall system to be able to unfold and fold the eave panel on the top of the sidewall along with the movement of the sidewall automatically. More particularly, the present invention relates to a collapsible building with a sidewall system and a sliding, retractable roof on it. The present invention further relates to a retractable roof with a foldable ceiling. More particularly, the present invention relates to a collapsible building that applies a retractable roof with a foldable ceiling.
- The following background information may present examples of specific aspects of the prior art (e.g., without limitation, approaches, facts, or common wisdom) that, while expected to be helpful to further educate the reader as to additional aspects of the prior art, is not to be construed as limiting the present invention, or any embodiments thereof, to anything stated or implied therein or inferred thereupon.
- The invention is a system of foldable walls and a collapsible building with the system of foldable walls and a retractable roof. The system can be used to create a stable shield or enclosed spaces that can be used in houses, RVs, warehouses, etc.
- For fixed structures or for people using RVs for traveling, it is sometimes necessary to provide portable walls that can be easily opened to provide shade along the horizontal plane. Sometimes it is necessary to provide shade in both directions in the horizontal plane. Further, there is also a need to provide a shelving platform at the top of the wall to accommodate other items or devices such as solar panels, temporary sun/rain shades, etc. to be placed on its top. In the prior art, the portable wall is usually assembled in such a way that after the wall is built, the items or equipment to be installed on it is fixed to it. The disadvantage of this type of wall is that building two vertical walls at an angle to each other and the shelving plane on top of them requires several steps and sometimes the assistance of others. In many cases, the device installed on its top surface cannot be fixed effectively if the shelving plane is not secured. Therefore, it is necessary to provide a device/system that can automatically release the eaves at the top for the installation of the top device while the wall is opened.
- Traditional methods of obtaining similar sized enclosed spaces are mainly tents and prefabricated mini warehouses. Prefabricated mini warehouses are large and difficult to transport; in order to reduce the weight of transportation, they usually use materials with low weight, such as plastic, which are not stable enough. Tents are small in the stowed state, but the structure is not strong enough to withstand larger loads, such as high wind pressure, snow, etc. When idle or transported, the present invention reduces its volume when idle or transported by foldable walls and retractable roof, and the material uses formwork with a steel frame to improve load-bearing capacity.
- Due to the increased functional requirements for equipment or buildings, many different folding top covering mechanisms have appeared on the market. The more common ones are folding awnings and retractable glass roofs. Folding awnings are mostly used in buildings and RVs and are easier to install, but the shading effect is poor because the unfolded area is generally small; and folding awnings are mostly soft materials with no load-bearing capacity. Retractable roofs are mostly used in buildings, and the structure will be designed thicker for heat preservation, resulting in larger volume and mass, which is not easy to install and transport.
- In cases where there is a need for heat preservation, the simultaneous presence of a ceiling and a roof can create a hollow insulation layer. Retractable roofs in the prior art are usually do not have ceilings. Separately set ceilings are not stable and complicate the operation of the whole installation.
- This invention introduces one kind of sliding roof design with a foldable ceiling. It includes sliding rails, roof shells, and ceiling mechanism. The roof is designed as several layers. These layers are nested together. It can expand out when needed. The roof can be used on some expandable structure such as recreational vehicles or mobile houses. Compared to traditional sliding roof, this invention combines a foldable ceiling inside the roof. The ceiling can split the roof and room which offer a better thermal insulation function.
- This roof design was first applied on an expandable RV. The roof can be folded inside the largest piece of shell. Then each piece of shell can be retracted one by one. The roof can be pulled out either by hand or some mechanisms. Then there are ceiling parts inside the roof. The ceiling can be pulled out followed with roof.

FIG. 1 andFIG. 2 show an embodiment of the sidewall system.FIG. 1 shows the folded status of the sidewall system.FIG. 2 shows the side view of the sidewall system while deploying from the folded status to the unfolded status as shown by the dashed arrow direction inFIG. 2 . The sidewall system comprises a fixedwall 110, asidewall 120, and a single-side eave system 200. Thesidewall 120 is pivoted to the fixedwall 110 by one or several hinges, thesidewall 120 rotates in the horizontal plane around the hinge axis to unfold or fold the sidewall system. - The single-
side eave system 200 is attached to thesidewall 120. The single-side eave system 200 comprises agear rod 210, agear 220, aneave panel 230, adrive shaft 240, at least onesupport rod 250, and at least onehinge 260. Theeave panel 230 is attached to thesidewall 120 by one or more hinges 260. This configuration allowseave panel 230 to be rotated around the axis ofhinge 260. As shown inFIG. 1 , in the folded state,eave panel 230 andsidewall 120 are affixed together. As shown inFIG. 2 , while deploying theeave panel 230 rotates around thehinge 260 axis correspondingly. In the fully unfolded status, theeave panel 230 is approximately perpendicular to thesidewall 120. - In the embodiment, the
gear rod 210, thegear 220, and thesupport rod 250 constitute the mechanism that automatically unfolds and folds theeave panel 230 along with the movement of thesidewall 120 around the fixedwall 110. In this mechanism, thegear rod 210 is mounted and fixed to the fixedwall 110 without relative motion to the fixedwall 110 and cannot be rotated without a rotating shaft. Thegear rod 210 is coaxial with the pivoting axis of thesidewall 120. Thegear 220 is attached to and coaxial with adrive shaft 240 and does not have relative motion with thedrive shaft 240. The teeth ofgear 220 andgear rod 210 engage with each other. When sidewall 120 rotates,gear 220 rotates synchronously. Sincegear 220 and driveshaft 240 are fixed and coaxially connected, the shaft rotates synchronously withgear 220. Sincegear rod 210 is fixed, it remains stationary with respect to the fixedwall 110 during the rotation of thesidewall 120. Sincegear 220 is located on thesidewall 120, during the rotation of thesidewall 120,gear 220 is forced to rotate simultaneously around its own axis to maintain the engagement with the teeth of thegear rod 210. Therefore, whensidewall 120 rotates, it drivesgear 220 and driveshaft 240 to rotate simultaneously, and the rotation ofdrive 240 drives the rotation ofsupport rod 250, which eventually drives the rotation ofeave panel 230. The rotation ofsidewall 120 in the horizontal plane drives the rotation ofeave panel 230 in the vertical plane. As shown inFIG. 2 , at least onesupport rod 250 connects theeave panel 230 and thedrive shaft 240. One end of thesupport rod 250 is slidably pivoted on theeave panel 230 and the other end is securely coupled to thedrive shaft 240. When thedrive shaft 240 rotates, it drives thesupport rod 250 to prop up theeave panel 230. In the present embodiment, the rotation ofsidewall 110 around fixedwall 110 drives the rotation ofdrive shaft 240, which in turn drives thesupport rod 250 to raise or retract theeave panel 230. In another embodiment, to provide more stable support, the single-side eave system 200 further comprises 2 ormore support rods 250, the ends of eachsupport rod 250 on one side are slidably pivoted on theeave panel 230, and the other ends are securely coupled to thedrive shaft 240, thedrive shaft 240 rotates all thesupport rods 250 synchronously. -
FIG. 3A andFIG. 3B show the top view and schematic of the sidewall system while deploying respectively. The direction of the arrow inFIG. 3A indicates the direction of rotation ofsidewall 120. The direction of the arrow inFIG. 3B indicates the direction of rotation ofeave panel 230. - To prevent the entry of external debris and water droplets to reduce the life of
gear 220 and gear rod 21, the single-side eave system 200 further comprises shells for the gear rod and the gear. - In an embodiment, the shell for
gear 220 comprises an outer cylindricalgear rod shell 2102 arranged on the fixedwall 110 along thegear rod 210 and an inner cylindricalgear rod shell 2104 arranged on thesidewall 120 along thegear rod 210. The outer cylindricalgear rod shell 2102 and the inner cylindricalgear rod shell 2104 are two separate components. The separate configuration facilitates the repair or replacement of individual shells in case of damage. Outer cylindricalgear rod shell 2102 is always fixed to the fixedwall 110 and remains relatively stationary. The inner cylindricalgear rod shell 2104 is always fixed to thesidewall 120 and turns at the same angle as thesidewall 120 rotates. As shown inFIG. 2 andFIG. 3A , the inner cylindricalgear rod shell 2104 is shorter than the outer cylindricalgear rod shell 2102 in radius. This setup allows the inner cylindricalgear rod shell 2104 to be partially covered by the outer cylindricalgear rod shell 2102 during rotation, thus avoiding jamming and providing better protection. The outer cylindricalgear rod shell 2102, and the inner cylindricalgear rod shell 2104 jointly cover thegear rod 210 located between Space A formed by the relative rotation of the fixed wall and the sidewall asFIG. 3A shows. - In another embodiment, the single-
side eave system 200 includes aring gear shell 2202. Thering gear shell 2202 is mounted on the fixedwall 110, space inside thering gear shell 2202 accommodates the gear whengear 220 is close to the fixedwall 110 in Space B. -
FIG. 4A andFIG. 4B show a plurality of fixing elements and a single fixing element. In order to provide better support fordrive shaft 240, to make it rotate more smoothly, and to avoid bending, several fixingelements 300 have been installed. In an embodiment, 2 or more sleeves are applied as fixing elements, thesleeves 300 are fixed to thesidewall 120 at equally spaced distances along the axis ofdrive shaft 240. The fixing mechanism holds thedrive shaft 240 in the long hole ofsleeves 300 in thesidewall 120 so that thedrive shaft 240 can rotate in the hole but cannot be disengaged from the hole. The fixingelement 300 limits the position of thedrive shaft 240. In an embodiment, the fixingelement 300 is fixed to thesidewall 120 by fourscrews 310. - Another embodiment is shown in
FIGS. 5A-6B .FIG. 5A andFIG. 5B show the top view and schematic view of a collapsible building when the sidewall system is fully deployed.FIG. 6A andFIG. 6B show the top view and schematic view of a collapsible building while deploying from the folded status to the unfolded status. The collapsible building comprises two previously mentioned sidewall systems and a retractable roof system. - More specifically, as shown in
FIGS. 5A-6B , the building comprises a first sidewall system, a second sidewall system, and a retractable roof system. The first sidewall system comprises a first fixedwall 510; afirst sidewall 610 pivoted to the first fixedwall 510, thefirst sidewall 610 rotates around the first fixedwall 510 about a first pivoting axis; a first single-side eave system comprises afirst eave panel 710 hinged to thefirst sidewall 520, thefirst eave panel 710 rotates around a first hinge axis correspondingly. - The first single-side eave system is attached to the
first sidewall 610. The first single-side eave system comprises a first gear rod, a first gear, afirst eave panel 710, a first drive shaft, at least one first support rod, and at least one first hinge. Thefirst eave panel 710 is attached to thefirst sidewall 610 by one or more first hinges. This configuration allowsfirst eave panel 710 to be rotated around the axis of first hinge. In the folded state,first eave panel 710 andfirst sidewall 610 are affixed together. While deploying thefirst eave panel 710 rotates around the first hinge axis correspondingly. In the fully unfolded status, thefirst eave panel 710 is approximately perpendicular to thefirst sidewall 610. - In the embodiment, the first gear rod, the first gear, and the first support rod constitute the mechanism that automatically unfolds and folds the
first eave panel 710 along with the movement of thefirst sidewall 610 around the first fixedwall 510. In this mechanism, the first gear rod is mounted and fixed to the first fixedwall 510 without relative motion to the first fixedwall 510 and cannot be rotated without a rotating shaft. The first gear rod is coaxial with the pivoting axis of thefirst sidewall 610. The first gear is attached to and coaxial with a first drive shaft and does not have relative motion with the first drive shaft. The teeth of first gear and first gear rod engage with each other. Whenfirst sidewall 610 rotates, first gear rotates synchronously. Since first gear and first drive shaft are fixed and coaxially connected, the shaft rotates synchronously with first gear. Since first gear rod is fixed, it remains stationary with respect to the first fixedwall 510 during the rotation of thefirst sidewall 610. Since first gear is located on thefirst sidewall 610, during the rotation of thefirst sidewall 610, first gear is forced to rotate simultaneously around its own axis to maintain the engagement with the teeth of the first gear rod. Therefore, whenfirst sidewall 610 rotates, it drives first gear and first drive shaft to rotate simultaneously, and the rotation of the first drive shaft drives the rotation of first support rod, which eventually drives the rotation offirst eave panel 710. The rotation offirst sidewall 610 in the horizontal plane drives the rotation offirst eave panel 710 in the vertical plane. At least one first support rod connects thefirst eave panel 710 and the first drive shaft. One end of the first support rod is slidably pivoted on thefirst eave panel 710 and the other end is securely coupled to the first drive shaft. When the first drive shaft rotates, it drives the first support rod to prop up thefirst eave panel 710. In the present embodiment, the rotation of thefirst sidewall 610 around first fixedwall 510 drives the rotation of first drive shaft, which in turn drives the first support rod to raise or retract thefirst eave panel 710. In another embodiment, to provide more stable support, the first single-side eave system further comprises 2 or more support rods, the ends of each first support rod on one side are slidably pivoted on thefirst eave panel 710, and the other ends are securely coupled to the first drive shaft, the first drive shaft rotates all the support rods synchronously. - Similar to those described previously, in the present embodiment, the rotation of the
first sidewall 610 around fixedwall 510 drives the rotation of the drive shaft, which in turn drives the support rods to raise or retract thefirst eave panel 710. Thefirst sidewall 610 and the first fixedwall 510 form a first sidewall system in the open state, at which the state angle between thefirst sidewall 610 and the first fixedwall 510 is 180°. - The second sidewall system is configured in the same way as the first sidewall system. The first sidewall system and the second sidewall system in the open state are facing each other.
