Description

The invention relates to roof rail mounting devices for a passenger car. Roof rails - longitudinal logs (protruding handrails) on the roof, used for securing cargo or trunk (https://volvo-club.kz/faq/interes/159-termin-ru.html).

    There are various ways of attaching luggage racks on a car roof, for example, using devices for attaching transverse beams on the sides of a roof in apertures of drain grooves (WO 89/00519, publ. 01.26.1989) or by attaching transverse beams on a side of a roof in an aperture of a door with a hook for the edge of the roof (WO 2017/214063 A1, publ. 12/14/2017).

          It is known to install rails assembled with pre-profile metal brackets attached to them, repeating the body profile and having one connecting hole on each bracket, which, when installing the railing, are combined with standard threaded holes under the seals of the doorways of the car body and bolted (VAZ-car 2123 Chevrolet-Niva, https://chevniva.ru/ustanovka-rejlingov-na-shevrole-niva/).

   The installation of roof rails on a Nissan Qashqai Turbodiesel car is known, which can be carried out by the manufacturer or owner of the car by purchasing a ready-made set of rails with devices for attaching them to the car (https://www.drive2.ru/l/459925714972470485/). Installation of such a device for securing the rails is carried out in the roof drain in regular places, which are specially welded four plates on both sides of the drain (two on each side). The front device for securing the railing is a cast aluminum plate with openings in which there are two horizontal threaded holes for bolts securing the device to the car and two vertical holes for the studs on which the railing is mounted. The device is fixed in the roof gutter by tightly wrapping the bolts into horizontal holes until they stop in the welded plates, while the device on the other hand also abuts against such welded plates.

We draw attention to the fact that the manufacturer provided for the installation of rails in advance and welded special plates for the own design of the railing fastening device.

   The essence of the problem is as follows. Today, in numerous specialized stores, there are a lot of both model and universal roof rails. Their difference lies in the fact that model fastening elements are made for a specific make of the car, so it is not possible to mount them on other cars. Universal fixing elements are designed for installation on most modern vehicles of domestic and foreign manufacturers. It is much more difficult to install roof rails on a car, the design of which does not provide for the presence on the roof of standard openings for fastening elements

(http://auto-wiki.ru/ustanovka-rejlingov-na-kryshu/).

        The first difficulty to be faced is to find suitable rails .... The second difficulty is that since the plant did not count on installing roof rails, there are no amplifiers on the roof for them. Will have to do it yourself not only to strengthen the structure in places of fastening arcs, but also to make holes in the roof. It is worth considering that a lack of stiffness or improperly installed roof rails can push the roof.

Thus, the roof mounting system not provided by the manufacturer does not give luggage system manufacturers the opportunity to produce roof rails. And you feel the need for an additional roof rack.

   Below we consider the problem of installing a longitudinal railing fastener in a roof drain of a passenger car, which is usually covered by a molding, in the case when the car manufacturer has not provided any special elements that make it possible to use a roof drain profile for installing a railing fastener. The analysis of patent and scientific and technical information did not reveal a significant number of such solutions. And home-made constructions of devices for attaching rails with their installation often lead to significant repair work.

  A device for fastening a car railing is known, comprising two plates connected by means of fasteners, a boss with a hole with an internal thread, rigidly connected to the plates, one of the plates being made with sections having different heights and located along the length of the plate (RF patent 171866 useful model, publ. 06/19/2017) ..

 The device according to the patent is also characterized in that on the plates there are sections with bends formed by the bent part of the plates.

In addition, the device according to the patent is characterized in that the boss is attached to the outer side of one of the plates through an additional plate.

Based on the set of features, we select a solution according to the patent of the Russian Federation 171866 as a prototype.

         As a disadvantage of the prototype, it can be pointed out that the fastening option according to the patent does not have an additional insurance system for fixing the fastening on the car roof. In particular, in the case of installation of fasteners without monitoring the tightening torque of the fasteners, or under the influence of vibrations during operation, the plates may break apart, which may lead to loss of fixation of the fastening on the car roof.

      It is also necessary to note the large number of parts of the mountings of the prototype, which increases the complexity and installation time of the device on the car.

      The technical result consists in eliminating the disadvantages of the prototype and creating a fastening device for the car railing, which ensures its reliable and vibration-resistant fastening to the car body.

      An additional technical result of the claimed utility model is the expansion of the arsenal of means for mounting rails on cars that do not have regular places for their installation, which gives consumers the opportunity to choose the option to install rails on such cars.

      The technical result is achieved by solving the technical problem of creating a fastening device for a car railing, comprising two parts for fastening the device to the body, interconnected by means of fasteners, an opening with an internal thread on one of the parts for fastening the railing to the device, characterized in that the parts are: front bracket and connecting bracket, are profile elements of complex shape with horizontal and vertical planes, with each bracket and it has an inner end in the form of a vertical shank with holes for connecting the brackets to each other and an outer end in the form of a profile having a cross section in the shape of the letter “P” with an elongated upper crossbar representing the horizontal plane of the bracket, on which a longitudinal through slot is made, starting from the edge the bracket, and the sides of the bracket are spaced from each other at a distance that is tied to the width of the bottom of the gutter of the car roof, i.e. mainly using most of the width of the bottom of the drain.

       In the claimed utility model, in comparison with the prototype, additional protection (insurance) is carried out by the presence of a constructive slot in the brackets, which avoids the dismantling of rails during operation. The inventive design of the device provides its high resistance to vibration and vibrations that are transmitted to rails and devices for securing rails from baggage cargo, which can be up to 60-70 kg. In addition to the slot, the high resistance of the device to inertial fluctuations of the load is provided by the creation of a large area of support brackets on the bottom of the drain. This area is determined by the widest possible arrangement of the lower edges of the lateral sides of the bracket and their sufficient length.

      In addition, the device is characterized in that the hole with the internal thread is made on a nut or boss, permanently attached to the horizontal plane of the front bracket.

      In addition, the device is characterized in that a through slot of the outer end of each of the brackets has an expanded part at the entrance.

 The width of the through slot of the outer end of each of the brackets is calculated taking into account the thickness of the standard butt welding rib of the sidewall and the roof of the car body.

The height of the sides of the outer end of each of the brackets is calculated taking into account the distance from the lower edge of the bend of the standard butt welding rib to the bottom of the drain in the roof of the car body on which the device is mounted.

        In addition, the device is characterized in that when it is mounted on a vehicle, a gasket is installed under the sides of the outer end of each of the brackets. The presence of a gasket or its absence is not the essence of the claimed utility model. The need to install gaskets can be determined during operation of the device. The gasket can perform both a protective function (protection against possible damage by the lower edges of the sides of the bracket) and an adjustment compensation function to ensure tight installation of the device in the vertical direction, taking into account the height “h” of the side of the bracket and the distance from the lower edge of the bend of the standard welding ribs to the bottom of the gutter in the roof of the car body

         The inventive utility model of a fastening device for a car railing is presented below in one embodiment. The device consists of a front bracket 1 and a connecting bracket 2 (figure 1), which are profile elements of complex shape with horizontal and vertical planes. The brackets are interconnected by means of fasteners: bolts 3, nuts 4 and washers 5 (figure 3), used when installing and securing the device in the gutter (gutter) of the roof of a car. On the horizontal plane of the front bracket 1, a nut 6 is permanently attached with a hole with an internal thread for fastening the railing. Each bracket 1 and 2 has an inner end in the form of a vertical shank 7 with holes 8 (round or elongated) for connecting the brackets 1 and 2 to each other and the outer end 9 in the form of a profile 10 (Fig.2c), Fig.1, Fig.1. 5), having a cross-section in the shape of the letter “P” with an elongated upper crossbar representing the horizontal plane of the bracket, on which a longitudinal through slot 11 is made, starting from the edge of the bracket. The through slot 11 of the outer end of each of the brackets may have an expanded part 12 at the inlet (Fig. 2b).

The width of the through slot 11 of the outer end of each of the brackets 1 and 2 is calculated taking into account the thickness of the standard butt welding rib of the sidewall and the roof of the body of a particular automobile brand.

     The lateral sides 13 of the bracket are located at a distance “S” from each other, which is tied to the width of the bottom of the gutter of the car roof (Fig. 5), i.e. mainly using most of the width of the bottom of the drain.

The height "h" of the sides 13 ((Fig. 2a), 2c), 3a), Fig. 5), the outer end of each of the brackets 1 and 2 is calculated taking into account the distance from the lower edge of the bend 14 (Fig.5,6,7 ) of a regular docking welding rib 15 (Fig. 5,6,7) to the bottom of the drain (gutter) 16, on which the device is installed. The height "h" of the sides 13 may depend on the brand of the car.

    An extended, for example, rounded part 12 at the beginning of the through slot 11 is designed to facilitate the entry of each of the brackets 1 and 2 into the corresponding standard welding butt fin 15 of the sidewall and the roof of the car body, while at the places of installation of the brackets 1 and 2, the welding rib 15 has an increased height (compared with the low part of the rib) and bends 14. The welding rib 15 is located in the drain (gutter) 16, which is available on both sides of the roof of the car. The gutter 16 is closed on top by a molding (not shown). The presence of bends 14 on the welding rib 15 is a prerequisite for mounting the device on a car. To increase the rigidity of the connection of the front bracket 1 and the connecting bracket 2, a reinforcement plate 17 is welded to the vertical shank 7 of the front bracket 1. In another embodiment, the reinforcement plate 17 can be permanently attached to the connecting bracket 2.

     The dimensions of the brackets 1 and 2 are determined primarily by the design of the drain and the welding rib of the car brand for which the claimed device for fastening the railing is intended.

    Installing the device on a car is as follows.

The molding is removed on each side of the car. In the place of fastening of the railing, a front bracket 1 is installed (with a nut 6 for fastening the railing) by inserting it under the bend of the welding rib at the bottom of the gutter 16 due to the presence of a through slot 11 with a rounded entry part. Then, in the same way, the mounting bracket 2 is installed under the adjacent bend of the welding rib. The brackets burst to the end of the through-cuts 11 to the edges of the weld in the area of its increased height and the beginning of the bend and then are rigidly fastened together using fasteners 3-5, forming a reliable and reliable connection of the device with the body. In railing, in the place corresponding to the axis of the threaded connection of the nut 6 of the device, a hole is made for its fastening to the device by any of the known methods. After installing four devices (two on each side) in the gutters (gutters), and then rails on each side, moldings are installed. The design is checked for durability of fastening of rails.

      In the main or other versions, depending on the brand of the car, it is possible to use gaskets for the lower edges of the U-shaped profile of the device. Gaskets may be needed, for example, to prevent damage to the paintwork of the car roof at the installation sites. In addition, in some cases, the gaskets can play the role of compensating, to ensure the density of the device on the car, as described above.

    The claimed embodiment of the device is intended for installation on passenger cars of the following brands: Lada XRAY, Renault Captur, Hyunday Creta, Mazda CX5, Hyunday Santafe, Hyunday Tucson and other representatives of the SUV, B, C. segment

    Technical appraisal and economic advantages of the claimed utility model consist in creating a reliable design of a device for fastening a car railing on cars that do not have regular places for fastening the railing, but have a gutter on the roof.
