Automatic car tent with spring mechanism, retractable rope and anti-theft chain

Abstract

This invention involves the design and manufacture of an automatic car tent with a spring mechanism and a central retracting rope system that covers or retracts the car in seconds without the need for electricity or a motor. The tent is made of lightweight, waterproof and UV-resistant materials and includes an internal locking plastic chain to prevent theft and wind. **The opening process begins by placing the tent on the roof and pulling the central rope, and the spring automatically opens the tent; retraction is done by pulling the rope again.** This tent is suitable for all types of passenger cars and SUVs, and with its anti-theft design (chain with front and rear outlets for locking to its own beads or snaps) and light weight, it solves the problems of manual (time-consuming and heavy) and electric (energy-intensive and high-maintenance) tents. **Compared to prior art, it is an innovation in the combination of spring and rope without external energy and an anti-wind / theft chain system.** Its application is in public and private parking lots, automotive accessory manufacturing industries, and exports to countries around the world, especially neighboring countries such as Iraq, Afghanistan, and Oman. This invention provides effective protection of the vehicle against sun, rain, snow, and dust with high speed and safety.

Description

Description of the invention Title of the invention Automatic car tent with spring mechanism, retractable rope and anti-theft chain Technical background of the relevant invention This invention falls within the field of automotive accessories, specifically **systems** for automatic vehicle protection against environmental factors such as sun, rain, snow, and dust. Its technical scope includes spring and rope-driven mechanisms for quickly and safely covering passenger and SUV vehicles. Technical problem and stating the objectives of the invention **The main problem** with car tents is the time-consuming process of opening and closing manually (requiring 1 to 2 people and a lot of force), heavy weight, risk of theft due to lack of locking, and the need for external energy (electricity or motor) in electric models, which has a **high** maintenance cost. The goals of this invention are to provide a light, fast (open / fold in a few seconds), safe, and external energy-free tent that completely covers the car, is anti-theft, and can be used for all types of cars. A description of the state of the prior art and the history of developments related to the claimed invention. A review of domestic and international patent records shows that car awnings are mostly manual or electric. In Iran, patent number 72183 (1721) refers to an automatic car awning with a simple mechanism, but without a spring and a ~~smart~~ rope. Patent number 72388 (1721) describes a spring-loaded car awning, but without an anti-theft system and a central rope. More recently, patent number 117322 (1077) introduces an anti-theft retractable car awning that is stored in the trunk, but requires an electric mechanism. Internationally, patent US6513858B1 (2003) describes a roll-up awning with a spring roller, but limited to partial coverage and without a ~~smart~~ rope. Patent US5597196A (1997) has a trunk storage system, but is electric. Patent CN106677570A (2017) introduces a fully automatic awning with a motorized roller and spring, but it is dependent on electricity and lacks an anti-wind chain. Patent US8070211 (2011) has an automatic awning in the trunk, but it is heavy and not anti-theft. By combining a spring, a central rope and a plastic chain, this invention creates an innovation in speed, lightness and no need for energy, and solves the problems of theft and wind. - Providing a solution to an existing technical problem along with an accurate, sufficient, and integrated description of the invention This invention combines a spring mechanism (similar to that of travel tents) and a central retracting rope system, making the opening and closing process automatic and fast. The lightweight material (UV-resistant polyester) and anti-theft design (chain with lock) increase efficiency. When folded, the tent is compact and portable. Explanation of shapes, maps and diagrams - Figure 1: Comprehensive plan, side and top view of the tent unfolded on the vehicle, showing the location of the central retractor rope (number 2: tension rope), the inner spring (number 1: spring mechanism) and the lower chain (number 3: locking chain). -Figure 2: Tent opening spring diagram, side and top view of the tent with spring dimensions for different sizes S (480-420 cm long), M (490-450), L (510-480), XL (530-490) and XXL (550-520). Lines included in green. -Figure 3: Spring and tent retractor rope mechanism with rope dimensions for different sizes S (360-320 cm long), M (380-350), L (400-370), XL (420-390) and XXL (440-410). Lines included in yellow. -Figure 4: Anti-theft, lockable, absorbent plastic chain (front / rear outlets) and internal wind with chain dimensions for different sizes: S (340-380 cm long), M (360-400), L (380-420), XL (400-440) and XXL (420-460). A clear and precise statement of the advantages of the claimed invention over prior inventions. Advantages over previous inventions: - No need for a motor or electricity, unlike electrical patents such as CN106677570A. - High speed and convenience, unlike manual ones. - Light weight and easy to carry. - Anti-theft and windproof design with new chain compared to US6513858B1. - Usable for all types of vehicles (various sizes). Description of at least one implementation method for implementing the invention The user places the folded tent on the roof of the car (No. 2: central rope). By pulling the rope, the spring mechanism (No. 1) is activated and the tent opens in a few seconds. The lower chain (No. 3) is removed from the front / rear bumpers and locked to its own beads or towbar to be windproof and theft-proof. To fold, the rope is pulled and the spring (No. 2) folds the tent. This method is safe and requires no additional tools. Explicit mention of the industrial application of the invention This invention is used in public / private parking lots to protect the paint and cleanliness of cars, accessory manufacturing industries, protective equipment manufacturing companies, and exports to countries around the world, especially Iraq, Afghanistan, and Oman.
