Description

DETACHABLE ROLL CAGE FOR VEHICLES DESCRIPTION

[0001] Removable roll cage for vehicle protection TECHNICAL FIELD

[0002] The present invention is developed in the technical field of vehicle equipment to protect occupants from being harmed in the event of an accident or other traffic risks, specifically it refers to a rollover cage mounted inside wheeled vehicles. BACKGROUND OF THE INVENTION

[0003] With the growing popularity of cars and the continuous development of technology, off-road vehicle users have quietly become a new consumer group. However, the likelihood of rollover accidents in off-road activities is much higher than in normal car driving, where the vehicle's cabin is easily deformed by external forces, also injuring the occupant.

[0004] Therefore, there is an urgent need to develop a support structure that can be used in vehicles to ensure the cabin has a safe space for occupants, particularly reducing the impact on the occupants in a rollover. In response, patent application CN214420397U, entitled “Rollover Carrier for Vehicle,” was developed, comprising a rear support, right side support, left side support, upper connection, and rear connection; patent GB2306408, entitled “Rollover Cage for Minibus,” was also developed, comprising roof struts, side vertical struts, center vertical struts, floor mounting plates, and However, they lack components that cushion the direct impacts caused by a pothole that jolt the occupants with the cage components; they lack supports that allow the driver and co-driver to be protected from hitting the front of the vehicles; they also lack a series of joints that facilitate quick assembly and disassembly for the interior of the motor vehicle. DESCRIPTION OF THE INVENTION

[0005] As a solution to the aforementioned problems, the present invention is developed, revealing a detachable roll cage for vehicle protection that allows the driver, co-driver and passengers to be protected by increasing the resistance against deformation of the motor vehicle body, and also has the advantage of having a curved configuration that allows it to adapt to different types of vehicles.

[0006] The roll cage comprises sections of pipe with convex and concave angles, including a plurality of coupled arches stabilized by crossbars; coupling pieces mounted between the pipes for assembly and disassembly; impact protectors that reduce direct impacts caused by the vehicle when passing over a slope, preventing the pipes from injuring the occupants; supports for attaching sunshades, seat belts, emergency hammers, and / or accessories; and body anchors.

[0007] The aforementioned coupling pieces can have various shapes suitable for fixing between the arches and the crossbeams, which are preferably of the omega, sliding, overlapping, circular trapezoidal type and may have holes for assembly and disassembly.

[0008] The present invention has the advantage of producing different configurations of crossbars and arches that allow the roll cage to be mounted on different vehicles such as minibuses, microbuses, vans, all-terrain pickups, ambulance vehicles, double cab, single cab or vehicles that have electronic devices on the roof.

[0009] To extend the lifespan of the foam components, quick-contact protectors are mounted on them. These protective components prevent scratches, bites, and pinches that can be caused by the occupants to protect themselves from the direct impacts of a rollover or vehicle crash, thus protecting against vehicle accidents and safeguarding people's lives.

[0066] It should be mentioned that, the rings (421a, 423a) slide over the surface of the arch tubes (21, 31) and straight sections of the crossbar (5) after the bent or twisted configuration is obtained, the lateral ends of the crossbars (11, 12) are mounted to the circular trapezoids (421b, 423b), after positioning themselves on the arches (2, 3) and arms (1) and the hollow appendages of the sliding couplings (42) are coupled concentrically, the roll cage is stabilized by threaded elements.

[0067] Figure 14 shows a third example of a preferred embodiment of the coupling pieces (4), showing that overlapping couplings (43) are fixed in the upper area of ​​the arches (2, 3), in the intermediate section of each front arm (1), and at each of the ends of the front crossbar (5).

[0092] Figure 32 illustrates a sixth example of a preferred embodiment of the roll cage, in the case it is mounted inside vehicles with electronic devices such as air conditioning, which, although comprising three front arches (3) and a rear arch (2) as shown in the first example embodiment, the configuration of the front arches (3) has two curved sections (31 b) at each upper end as shown in the figure.

[0093] Depending on the vehicle type, the rear roll bar (2), front roll bars (3), or front arms (1) can be obtained from a single piece of tubing, even by high-temperature melting or by means of welding electrodes, such as the pipe sections of the front crossbeam (5) and the side crossbeams (11, 12).

[0094] In these, points are drawn on each entire tube of the pipe sections, these points define longitudinal dimensions and limit the segments of the straight sections, to then perform the bending and shape the curved sections as required, this bending is done at the points drawn between the segments, forming the angular configuration of the front arms (1), the rear arch (2), each front arch (3), the front crossbar (5) and the side crossbars (11, 12).

[0096] While the anchoring elements are fixed to the lower floor of the vehicle body and for their stability connections are made such as threaded joints that pass through the through holes, the threaded joint can be composed of threaded elements such as nut and bolt, in addition the threaded joint facilitates assembly, disassembly and ensures a stable connection.

[0097] The aforementioned pipe sections of the front arms (1), the rear arch (2), each front arch (3) and the side crossbars (11, 12) can be of circular tubular section, or also of section composed of polygons and circular arch; hollow concentrically.
