- Such a structure has a low resistance to deformation under the action of bending moments arising in the longitudinal plane during the movement of the elevator doors or physical impact from the users, which can lead to bending of the strip for securing the elevator flap, further distortion of the elevator flaps and jamming of the shaft or elevator car doors.
- the known devices often have an asymmetry of the sides of the elevator flaps, due to the fact that the upper and lower strips for fixing the elevator flaps have different designs.
- the strips for securing the elevator sash differ in their profiles, as well as in the shape of the mounting holes and their location, as a result of which, in order to install the elevator sash in the door opening mechanism, its corresponding orientation in the opening is required, which complicates the installation process of the sash, as a result of which it becomes necessary to create a new solution in the design of the lift door.

- the strip for securing the leaf in the mechanism for moving the elevator door has a rectangular L-shaped profile, thereby increasing its resistance to bending moments arising from the movement of the elevator door, thereby increasing its deformation resistance.
- the strip for fixing the leaf in the mechanism for moving the elevator door can be provided with a stiffener, which also increases its deformation resistance.
- the strips for securing the sash in the mechanism for moving the elevator door have a rectangular L or U-shaped profile, since such a profile provides minimal mobility of the strip inside the groove and excludes the possibility of loss of contact of the strip with the groove surface, as a result of which reliable fixation is ensured strips for fixing the leaf in the mechanism for moving the elevator door and, as a result, increases its deformation resistance.
- the strip for securing the sash in the mechanism for moving the elevator door is formed by flanging the upper and lower edges of the sheet blank metal along the ends into the inner region of the workpiece at an angle of 180 °.
- This value of the angle is due to the fact that when the edge of the workpiece is bent to an angle less than 180 °, a gap is formed between the strip for fixing the sash in the mechanism for moving the elevator door and the sash, which during operation of the elevator sash can lead to the formation of additional bending moments acting on a bar for fixing the leaf in the mechanism for moving the elevator door, as a result of which its profile can be deformed, which ultimately can lead to a skew of the elevator leaf and to the occurrence of an emergency situation.
- the strips for securing the elevator sash are displaced at the same distance from the edges of the sash, due to which a space is formed, limited by the sash and the strip, the size of which allows the installation in it of both the mechanism for moving the elevator door and the shoe of the threshold of the elevator door, therefore, when the installation of the sash eliminates the need to orient the sash sides with respect to these mechanisms, as a result of which it simplifies the installation of the sash in the elevator and increases the maintainability of the elevator sash, since it is possible to reposition the damaged and usable sash.
- the distance from the edges of the sash to the strips can be in the range of 1-5% of the sash length, which eliminates the need for spatial orientation of the sash when installing it in most existing mechanisms and further simplifies its installation.
- the side walls can be made in the form of a triangular, trapezoidal or rectangular profile by bending, rolling or stamping.
- the sidewalls are rectangular C-shaped and are formed by bending the side edges of the sheet metal blank along the ends into the interior of the blank, thereby increasing the mechanical strength of the elevator flap.
- the strips for securing the leaf in the mechanism for moving the elevator door and the side walls can be connected to each other by means of detachable or non-detachable connections.
- the strip for securing the flap in the mechanism for moving the door of the elevator and the side walls can be connected to each other using rivets, which further increases the deformation strength of the strip for securing the flap in the mechanism for moving the door of the elevator.
- the elevator flap securing bars have mounting holes for securing the elevator flap, which can be made by various metal processing methods such as chopping, cutting, punching and various shapes such as rectangular, round or oval.
- both elevator flap fastening strips have rectangular mounting holes for securing the elevator flap, which are designed to fit the elevator flap into the mechanism for moving the elevator door and the elevator door sill shoe, while such mounting holes are the same in shape and location on the strips.
- longitudinal holes can be made on the elevator sash fastening strips to provide access for installation tools to the mechanism for moving the elevator door or the elevator door sill shoe, which also further simplifies the process of installing and disassembling the sash from the elevator and increases its maintainability.
- the bars for securing the elevator flap and the side walls can be connected to each other by means of detachable or non-detachable connections.
- the strip for securing the elevator flap and the side walls can be riveted together.
- the side walls have grooves for fixing a strip for fixing the elevator flap.

- the side walls and strips for securing the leaf in the mechanism for moving the elevator door can be made by the same methods of sheet metal processing, such as punching, rolling, flanging.
- the grooves are made in the edge of the side wall having a rectangular C-shaped profile, since in this case the deformation resistance of the strip for fixing the leaf in the mechanism for moving the elevator door is increased by maintaining the rigidity of the elevator leaf.
- the shape of the groove repeats the external shape of the profile of the strip for securing the leaf in the mechanism for moving the elevator door, since this provides the maximum contact area of the strip for securing the leaf in the mechanism for moving the door of the elevator with the groove surface, which additionally increases the deformation resistance of the elevator door.
- the grooves are made at the same level with the strips for fixing the sash in the mechanism for moving the elevator door, due to which, in the assembled form of the elevator sash, the slats are connected to the surface of the groove, thereby ensuring reliable fixation of the strip in the wall and, therefore, increasing its deformation resistance.
