Description

The present utility model relates to a sunshade roof for wagons equipped with a cantilever arm, in particular a roof for protecting the wagon from the sun or a sunshade roof.

As the economy has developed very rapidly in recent years, outdoor recreation has become one of the main activities of city dwellers on holidays. Therefore, an easily detachable or collapsible roof for protection from sun, rain and wind is one of the most important means for untroubled recreation, especially a roof integrated with the body is very popular among the masses. As shown in Fig. 9 and 10, such a sunshade roof essentially consists of a stationary frame 10, an articulated and movable frame 30, with a pull handle 301 in the middle of the movable

Scaffolding is arranged, a clamping base 302 is provided, and two supports 303 with the same design and two telescopic rods 304 with the same design are arranged on the movable scaffolding 30, the two supports 303 being provided at both ends of the movable scaffolding 30 and a base frame 305 being arranged at the lower end of both supports 303 (see Fig. 11), so that when the roof fabric is unfolded they serve as support columns on both sides of the sunshade roof, and one end of both telescopic rods is connected to the movable scaffolding 30, while the other end is connected to fastening base 101 in the middle of the stationary scaffolding 10, so that when the roof fabric is unfolded the two telescopic rods 304 are formed as a V-shaped support frame guided transversely under the roof fabric to support the roof fabric 20, and an elastic roller 102 is arranged in the inner cavity, so that the roofing material 20 can be rolled up by means of this elastic roller 102. As shown in Fig. 11, in use, the stationary frame 10 is fixed to one side of the carriage and the pulling handle 301 on the movable frame 30 is pulled to pull out the roofing material 20 rolled up in the stationary frame 10, and the two telescopic rods are thereby extended to form the support frame under roofing material 20. When a corresponding length of roofing material 20 has been pulled out, the two supports 303 arranged at both ends of the movable frame are folded down so that they rest against the ground so that the roofing material is secured between the carriage and the upper end of the two supports.

Although the goal of protection from the sun can be achieved with the help of this sunshade, it still has the following shortcomings when used:

1. Since the roof fabric of such a sunshade is fixed by means of the car and the upper end of the two supports, this sunshade can only be installed on the outside of the car and can only serve as a sunshade for a place next to the car. When the car is parked outdoors under the sun, this roof cannot be used as a sunshade covering the car.

so that the application area of this sunshade roof is considerably limited.

2. Since this sunshade must be fixed to one side of the vehicle using a stationary frame, it is only suitable for certain vehicles, but not for small trucks, and it is also impossible to install such a sunshade for cars due to the small height of cars. So the application range of such a sunshade is very limited. Since the length of the vehicle where the sunshade is fixed is limited, it is only possible to install a sunshade of a certain length. Therefore, its sunshade area is limited. Such a sunshade has not proven itself well in practice.

3. Since such a sunshade is attached to one side of the car with the help of its stationary frame, the installation must be carried out by a special workshop. It is impossible for users to install such a sunshade on the car themselves, and it is not so simple and easy to carry out the installation.

4. Since such a sunshade must always remain on one side of the car after installation, not only will the aesthetic effect of the exterior be affected, but also the airflow resistance due to the sunshade installed on the car will increase, especially when driving at high speed, so that the balance when the car is driving will be affected. It is very dangerous.

The present utility model is based on the task of creating a sunshade for a car for recreational purposes, equipped with a boom arm, in which all of the above-mentioned deficiencies are eliminated, whereby a clamping device is clamped to the fender of the front and rear tires of the car, to which a mast is connected, to the upper end of which a boom arm is connected, and the boom arm unfolds in the principle of the mechanism of parallel, equally spaced crank arms.

and is contracted when the movable end of the boom arm is moved, and the roof fabric connected to the boom arm is also unfolded and retracted, so that the aim is achieved of providing a sunroof for the wagon both for protection of the wagon from the sun and for recreation, which is light and simple to unfold and reset.

The problem addressed by the present utility model is solved by providing a sunshade roof for the car equipped with a cantilever arm, consisting of a clamping frame, mast, positioning plate, cantilever arm and roofing material, characterized in that a clamping device is arranged on the clamping frame, which is clampably attached to the fender of the car above the tire, the lower side of which is connected to a telescopic tube so that the telescopic tube can move the clamping device, and a movable sleeve is arranged in the bottom part of the clamping frame, and the cantilever arm is formed from several intersecting and rotatably connected rod bodies, the ends of which are pivotally connected to one another so that a mechanism of parallel, equally spaced cranks is formed, and the upper end is connected to the positioning plate from the inside of the cantilever arm, while its lower end is fastened by means of a screw leading through the slot so that a movable end that can be moved along the slot of the positioning plate is formed, and the roofing material is fastened to the upper end of the cantilever arm. is.

The task of the present utility model can also be largely solved by the following technical features:

In the sunroof of a recreational vehicle according to the utility model, the upper end is attached from the inside of the boom arm by means of a clamping ring and is located between two adjacent intersection points of rod bodies, while the other end of the clamping ring serves as an access.
