Description

The invention relates to the field of auto repair work and is intended to protect the vehicle from damage, for example, paintwork from scratches, oils, bumps, etc., which inevitably occur during repair.

Analogs

The well-known solution US 9186972 "Protective cover for vehicle front ends" is a protective cover mounted on the front of the car, consisting of a mesh web and having fastenings in the form of buttons and sockets, elastic belts. This solution is intended, as stated, to protect the car paintwork.

The disadvantage of this solution is the mesh material, which during repair cannot effectively protect the paintwork, for example, from scratches that appear from tools, impacts of falling tools, from drops of oil or other liquids, which, moreover, spoil the paintwork of the car, but also increase risk of fire. In addition, the disadvantage is the difficulty of mounting in the form of latches, rubber bands, clips, which leads to time costs for installation. The complexity of the T-shaped structure of FIG. 3 - the presence of embedded rubber bands (22). Another drawback is the restriction of access to the elements closed by the apron, due to the fact that the apron is attached to the bottom, i.e. during the repair process, the master loses free access to the radiator grill, to the radiator, to the headlights, etc. Another drawback is that the design of this cover allows you to use it only for the front of the car due to the pattern and mounts (see US 9186972 on uspto.gov).

Another US Pat. No. 5,195,778 “Car utility apron” is known, which is an apron having a soft flexible outer layer with the number of pockets located on either side of the apron. The front of the apron has an insert of another material to allow the radiator to take air if the engine is running, while the apron is in place. An apron is attached in the engine compartment of the car with hooks at the top and an elastic band and also at the bottom. This solution is intended, as stated, to protect the car paintwork.

The disadvantages of this solution are the complexity of the design, as well as the insert that allows the radiator to breathe, coming from the very top, unable to protect the paintwork, for example, from scratches from tools, impacts of falling tools, from oil drops or other liquids. In addition, the design provides for a fairly complex installation both from above and from below. Another drawback is the restriction of access to the elements closed by the apron, due to the fact that the apron is attached to the bottom, i.e., during the repair process, the master loses free access to the radiator grill, headlights, wheel arches, etc. Another disadvantage is the material from which the apron is made, which in accordance with the description has the following characteristics: durable, flexible, soft, while it also has a second layer made of a soft substance. This apron is not able to protect against oils and other fluids used in various repair cases, which not only spoil, stain the paintwork, but also increase the risk of fire. In addition, the presence of two layers makes the design complex. Another disadvantage of this solution is that it can be used to protect only the front of the car. Also, the presence of many pockets located on the front side, especially loaded with tools, interferes with the master during the repair process, since during the repair he most often has to lean on, bend over through the wings or in front of the car. In this case, the master is more likely to get injured from tools located in the pockets, for example, an injection with a screwdriver, bruises, cuts, etc., from wrenches, cutters, etc. located in the pockets. In addition, the presence of pockets, especially filled with tools, can interfere with the work of the master, for example, he can cling to them with buttons, pockets, etc. on clothing, hoses, and other similar items can get stuck, squeezed, etc., which naturally leads to interference (see US 5195778 on uspto.gov).

Another US 5460305 Magnetically mounted tool pouch solution is known, which is a rectangle with magnets on all sides and on the surface of pockets. This solution is installed on the door surface and is used to place tools and accessories in them during repairs.

The disadvantage of this solution is that it is not able to protect the paintwork of the car due to the small area, in addition, it cannot be used on other surfaces of the car, except on the door, which is indicated in the description and in the choice of class B60J 11/06 ( to cover only specific vehicle elements, such as doors), and even if you place this product on the wing or in front under the hood of the car, it will protect a small part. Another drawback is the use of two layers of material: one simple, the second as described, absorbing oils, solvents and other liquids. Firstly, this complicates the design, and secondly, the impregnated layer increases the risk of fire and the duration of combustion. It should be noted that edge treatment with a border (50) (corner envelope) complicates the design. Another disadvantage when using this solution, for example, on the front of the car is the presence of protruding pockets located on the front side. Especially loaded with tools, they interfere with the master during the repair process, since during repairs he most often has to lean on, bend over through the wings or in front of the car. In this case, the master is more likely to get injured from tools located in his pockets, for example, an injection with a screwdriver, bruises, cuts, etc. In addition, the presence of pockets, especially filled with tools, can interfere with the work of the master, for example, he can catch on buttons on clothes, hoses and other similar elements can get stuck, squeezed, etc., which naturally leads to interference in the work. Another disadvantage is that installation only in an even taut position does not imply folding folds and installation at an angle.

Disclosure of invention

The objective of the claimed invention is the development of such a protective apron for a car that would have a simple structure, effectively protect the vehicle during repair from scratches, chips, oil, solvent and other liquids used in the repair of a vehicle, and is fireproof. In addition, it was easily mounted and dismantled, as well as allowing quick access to protected elements. The declared apron should be applicable not only to any one part of the car, but also to different ones. In addition, the claimed apron should not interfere with the work of the master, and also not harm his health.

The tasks are solved due to the apron, simple to manufacture, having a simple design based on a rectangular smooth canvas (Fig. 1), the edges of which are seam-hemmed with a closed cut (Fig. 3), while on one of the long edges in the seam processing the magnetic elements (3) of FIG. 1, by which the apron is attached to the vehicle body in any place, depending on what parts need to be protected during repair. This design is simple, including the manufacture, as well as installation and dismantling.

It should be noted that the magnetic elements (3) of FIG. 1, located at a distance from each other, allow you to adjust the angle of attachment of the apron, lay the folds, adjust the length, make bends and turns, etc., i.e. they protect not only a specific part of the car such as the front and wings, but, for example, part of the roof and one wing, hood and wings, etc., and also has a range of protection area, as it can even fold several times A condition to be fixed on some small-sized part.

In particular cases of execution of the magnetic elements (3) of FIG. 1 can be replaced by magnetic tape, which is flexible and also capable of forming wrinkles, adjusting in length, and making bends and turns.

In the particular case of execution, the magnetic elements can be additionally located on the side edges.

This arrangement of magnetic elements on one long edge or on one long edge and on the side edges allows free access to the protected elements of the car, such as headlights, bumpers, grille, etc., depending on where the protective apron is installed . In this case, the fastening in the form of magnetic elements (3) of FIG. 1 allows you to quickly and without harm to the paintwork to mount and dismantle the protective apron.

Due to the distances between the magnetic elements, the loose bottom and in the particular case of the bottom and sidewalls, a car without special cutouts and inserts can work quietly, taking air from the outside.

It should be noted that the hem in the hem with a closed cut (Fig. 3) can be replaced by a grind (Fig. 4), stitched on the wrong side or on the front side, into which magnetic elements (3) and / or magnetic tape are also sewn.

Another difference from analogues is that the magnetic elements (3) of FIG. 2 are fixed, preventing side movement within the seam, i.e. two sewing seams (2.1) are laid on the sides of the magnetic element (3), and / or glue and / or welds, the magnetic element (3) can be glued inside the edge treatment of the protective apron with glue from two or one side to the protective canvas.

In addition, another difference from analogues is the material of which the apron is made, namely, this canvas (1.1) of FIG. 3, soft, allowing to lay folds, strong, abrasion-resistant, liquid-impermeable, liquid-absorbing, in particular cases may have water-repellent and / or refractory impregnation, for example, polyurethane or polyvinyl chloride, providing resistance to solvents and water resistance of fabric with a PU coating from 200 to 5000 mm of water.

In special cases of manufacture, the material used can be rubberized (1.2) of FIG. 3 on one or both sides, which additionally protects against the penetration of liquids, as well as during impacts, absorbs part of the impact force and prevents damage to the car.

It should be noted that in the particular case of edge processing by turning (4) of FIG. 4, it can be made from the same material, or from another having the same characteristics as the main material of the apron.

The density of the material without impregnation and rubberization in the claimed solution is from 200 to 600 den.

It should be noted that in the claimed solution to the apron in the form of magnetic elements, permanent magnets, for example neodymium, are used.

The preferred strength of the magnetic element is 1.3-1.6 kg.

For example, in the case of using neodymium magnets, it is preferable to use the following magnets: in the form of a disk with dimensions d 10 × 3 mm with an adhesion force of 1.8 kg and / or in the form of a rectangle with dimensions 18 × 10 × 1.5 with an adhesion force of 1.3 kg Moreover, the number of magnets on one long side is preferably from 8 to 15 pcs., And on the side short side from 3 to 5 pcs.

The dimensions of the protective apron in relation to the aspect ratio can be varied, but preferably in the range of length 3200-4000 mm, width 750-1300 mm.

It should be noted that when sewing the edge, the machine sewing seam (2) of FIG. 2, 3, 4 and / or manual, but can also be made of adhesive or welded.
