Abstract: A sofa bed can solve the problem of where to place a sofa in a smaller space or inside a recreational vehicle. The sofa can be completely flattened out to become a sofa bed. When not needed or when space is limited, the sofa bed can be folded directly against the wall. The sofa bed can include a back support cushion, a seat cushion and a leg rest. The back support and seat cushions can be supported by a frame underneath. A system of spring-loaded rods can be under the leg rest. These parts can be completely flattened or turned into a sofa, with the leg rests covering the frame underneath the sofa. The sofa can be folded to the wall, controlled by hydraulic rods at the bottom. The legs of the sofa bed and the hydraulic rods can be designed to not protrude from the wall when folded.

Abstract: A mobile expandable structure can expand both outward, from at least one side thereof, and rearward, from a back side thereof. When expanded, the mobile expandable structure can provide an expansion of about 2.5 to about 3 times the original living space provided by the main structure.

Abstract: An expandable structure has an expansion section with side wall panels that can stack into and be deployed from a wall enclosure central housing. A track can be deployed on the wall enclosure for facilitating the movement of wall panels into and out of the central housing. This innovative configuration not only enables efficient and accurate storage of each wall panel within the central enclosure but also concurrently serves as the foundational support structure for the cabin. After the wall panels are deployed and the structure is fully expanded, the wall panels can be tightened together to provide sound and weather protection.

Abstract: A foldable enclosure can turn an outdoor spa or swimming pool into its indoor counterpart, allowing the pool or spa to be used when the outdoor temperature is cold or when the weather is bad. An expandable room-like structure can cover the pool or spa in the back yard of the house. When the structure is not used, it can be retracted so it does not occupy much space in the house or in the back yard. The enclosure can include a sliding cover that can be used to cover up the pool and to allow people to walk on it. The expandable structure includes a sliding outer wall, two rotating side walls, a sliding wall seal, and several roof blocks.

Abstract: An expandable home structure includes a main structure and a first expansion section that is expandable outward in a first direction from a first side of the main structure. Once the expansion section is expanded, coverage members can unfold from a bottom of the floor member and the floor member can be lowered within the unfolded coverage members, thus providing a sunken floor for the expanded section. The floor member may fold vertically against the main section in the folded configuration. After the front and rear walls are unfolded from the main section, the outer wall of the expansion section can be moved outward from the main section to cause the floor member to lower into its horizontal, expanded, and raised position. The coverage members can be unfolded from the bottom of the floor member and the floor member can be lowered.

Abstract: A self-cleaning foldable solar panel system with a foldable support system and a self-cleaning unit is provided. The foldable support system is composed of a main support board, a first support board, and a second support board. The solar panels of the array are mounted on support frames of the support boards by means of worm wheels. The folding support system allows the solar panels to save space when they are not in use. The support frame provides tilt angle adjustment for the solar panels. The worm wheels allow the solar panel to be adjusted to rotate horizontally. The reciprocating motion and rotation of the rotary brush that works when the system is in folded status make it possible to keep the system clean by brushing it automatically. Compared to traditional solar panels, the present self-cleaning foldable solar panel system is portable, angle-adjustable, and self-cleaning.

Abstract: A detachable storage space, such as a movable closet, can be mounted on the back of a vehicle, such as a recreational vehicle. The detachable storage space differs from a trailer, which can lead to a worse driving experience. When the detachable storage space is mounted on the vehicle, it will be similar to a spare tire mounted on a back of a sport-utility vehicle, for example. A lifting structure on the backside of the vehicle can lift the detachable storage space and lock it on the vehicle structure. The detachable storage space can include wheels and a small motor to permit users to move and control it remotely.

Abstract: A multilink structure provides for a stabilizer system for an expansion section of an expandable structure, such as for a slide-out of a recreational vehicle. The stabilization system can be securely mounted onto either the chassis or the extension track, offering versatility for different configurations. Due to space constraints on the chassis, the stabilizer is engineered to remain horizontally aligned when retracted, maximizing available space. The primary connection point for the multilink stabilizer system is the chassis structure, with the outer wall attached as a secondary support. During deployment, the outer wall ingeniously combines pushing and rotational forces to smoothly extend the stabilizer assemblies outward. Once fully extended, the stabilizer adopts a fully vertical position, providing vital stability and support for the expansion section or slide-out.

The horizontal adjustable awning includes an internal control mechanism, a main transmission mechanism and a folding mechanism. The internal control mechanism includes a spring roller, a drive belt, a belt end block and a block snap; the main transmission mechanism includes a pulley, a filament rod, a shade cloth mechanism, a bearing housing, a rack and pinion mechanism and a gear housing; the folding mechanism includes two rotating pushers, two articulated sliders and a protective plate.

Abstract: A table, such as a coffee table, can be quickly folded and unfolded. The coffee table can be used indoors or outdoors. Compared with the traditional coffee table, the folding coffee table can be quickly unfolded and folded, and can be put away to gain more space under the condition of limited space indoors and can also be used as a temporary table outdoors. There is a carrying handle in the center of each of the two long sides of the table, which can be unfolded by holding it and lifting it upwards. When deployed, the coffee table can provide a stable structure for use. In the folded state, on either side of the short side of the tabletop are folded up support legs. On either side of the long side of the tabletop are two carrying handles to assist in unfolding and retracting the coffee table.

Abstract: A roof-based system for electric vehicles can be equipped with an array of wind turbines and expandable solar panels that are designed to generate electricity for the operation of electric vehicle. The wind turbines can harness the power of the wind while the vehicle is driving, and the solar panels can be fully extended when the vehicle is parked, maximizing the conversion of solar energy into electrical power. The generated energy can then be stored in the vehicle's batteries, serving a dual purpose: it can either propel the electric vehicle or supply power for daily energy needs. This innovative roofing system represents a sustainable and eco-friendly solution that not only promotes renewable energy usage but also enhances the overall efficiency and eco-friendliness of electric vehicles.
