Description

The claimed utility model relates to the field of construction and can be used for installing external and internal doors in residential and industrial premises.

A door hinge with magnetic fastening of the fastening plates comprises a movable Fig. 2 (4) and a fixed Fig. 2 (3) half-hinges, each of which is made in the form of a plate with a hinge part Fig. 2 (13, 14), connected with the possibility of hinge rotation relative to each other by means of a rod Fig. 1 (8), protective covers Fig. 1 (6, 7), closing cavities made in the hinge parts of the half-hinges, and friction bearings Fig. 1 (5), wherein the plates of the movable and fixed half-hinges Fig. 1 (1, 2) are made with through holes Fig. 1 Fig. 2 (9), for fastening elements that ensure their fastening, respectively, to the door leaf Fig. 4 (15) and to the door frame Fig. 4 (16), the hinge part of the movable half-hinge consists of three sleeve elements Fig. spaced apart along the length of the half-hinge. 2 (14), the hinge part of the fixed half-loop consists of two sleeve elements spaced apart along the length of the half-loop Fig. 2 (13), located between the sleeve elements of the movable half-loop, and the plain bearings Fig. 1 (5) are located between the upper pair of adjacent sleeve elements of the movable and fixed half-loops and between the lower pair of adjacent sleeve elements of the said half-loops and are made with an outer diameter equal to the diameter of the sleeve elements of the half-loops. What is new in the proposed design of the door hinge is that it is provided with two fastening metal plates Fig. 1 Fig. 3 (11), made with a length exceeding the length of the plates of the movable and fixed half-loops, and a width that is greater than the width of the half-loop plates Fig. 3 and less than the thickness of the door leaf Fig. 4, the plates of the movable and fixed half-loops are made with openings Fig. 1 (12), in which fastening magnets Fig. 1 Fig. 3 (10) of a size corresponding to the mentioned holes, and the fastening metal plates of Fig. 1 Fig. 3 (11) are attached to the plates of the movable and fixed half-loops of Fig. 1 (1, 2) by means of fastening magnets.

The technical result of this utility model is a simplification of the cutting process and an increase in the reliability of cutting in door hinges.

When constructing houses and buildings of any purpose, it is necessary to install doors. The installation process is quite labor-intensive and complex, requiring precise cutting of door hinges into the door block and reliable fastening. Minimal deviations during the installation of hinges lead to skewing of the door leaf or the appearance of gaps, which affects the reliability of the installation of the door leaf. This useful model allows you to solve these problems, make the cutting process easier and more reliable, significantly improve the quality of the installed door hinge and the door block as a whole.

At the moment, there are different types of door hinges that are used to install interior doors. The closest prototype is the door hinge utility model RU 182422 U1. The disadvantage of this utility model is the complexity of cutting, the lack of tolerance when cutting the door hinge, and the impossibility of adjusting it during installation. The need for a complete replacement of the door leaf if the door hinge is not cut accurately enough.

There are other similar PM door hinges that have all the listed disadvantages. All these door hinges require precise cutting into the door leaf and door frame, no possibility of cutting tolerance. If the door hinge is not installed accurately enough, this can lead to a skew of the door leaf or the need for its complete replacement, loss of reliability of the door hinge and door leaf fastening.

The purpose of this utility model is to make the installation of door hinges simpler and more reliable.

This is achieved by the fact that the door hinge with magnetic fastening of the fastening plates, containing a movable and fixed half-loop, each of which consists of a hinge part and a plate, respectively attached to the door leaf and to the door frame by means of fastening elements, in addition to the holes for the fasteners, has additional holes with installed fastening magnets of the corresponding size and fastening metal plates, which are attached to the door hinge by means of magnets and have dimensions in length and width greater than the dimensions of the door hinge plate and in width less than the thickness of the door leaf.

The novelty of this useful model is the presence of fastening magnets fixed in the holes of the door hinge plates, fastening metal plates that are attached to the door hinge by means of fastening magnets.

This useful model is quite easy to use. The door hinge is cut into the door unit with a small tolerance, the tolerance during cutting allows you to adjust the installation of the door hinge as needed. The door hinge is attached to the door unit using self-tapping screws. Then, fastening metal plates are attached to the door hinge from above, which fit tightly to the door leaf and door frame, the fastening plates overlap the door hinge plates and the tolerance that was made when cutting the door hinge fits tightly to the door unit and door leaf due to the installed fastening magnets. The fastening metal plates must completely overlap the dimensions of the door hinge plates and be smaller than the width of the door leaf and have an arbitrary shape. This will significantly simplify the cutting of door hinges and make the installation more reliable due to the possibility of adjustment. For more reliable adhesion to the door unit, the fastening plates can have an additional adhesive layer on the inside.
