RU2710129C2 - Safe door - Google Patents

Abstract

FIELD: chemistry.

SUBSTANCE: this method of injuries reduction is realized by arrangement of special pads made of rubber or rubber with hardness of 20–50 units on Shore, along side sides of door leaf. Since the material hardness is selected for maximum preservation of the physical characteristics of the door leaf, the use of such a door does not cause discomfort. Owing to cavities in the pad and the fact that the dimensions of the lining in the plane of door make 15 to 50 mm, the risk of injuries is considerably reduced. Application without cavities is also possible to reduce production costs.

EFFECT: invention has high economic feasibility and industrial applicability, possibility to arrange industrial production in a short period of time.

Description

The present invention relates to the field of construction and can be used to replace / upgrade conventional interior doors in residential or public buildings.

No analogues of safe doors are known [1]. The aim of the invention is to reduce or nullify the possibility of injury to citizens by pinching limbs when closing the door.

The goal is achieved as follows:

1. Lining made of rubber (or rubber of moderate hardness (20-50 units of Shore)) is installed on the vertical end parts of the door, long and wide in accordance with the length and width of the door leaf, the thickness of the linings is from 15 mm to 50 mm.

2. Fastening is carried out by bolting, glue is also allowed. Thus, the safety of use is achieved by reducing the hardness of the end parts of the door to a hardness below the values at which, in case of pinching, there is a violation of the integrity of the human limbs.

3. Moderate hardness of the linings is necessary to preserve the geometry of the door and its physical properties (protection from noise, structural rigidity, etc.)

4. Pads can be used with horizontal cavities on the inside along the outer corners.

The invention is carried out in the following way:

(Fig. 1) A door leaf (made of wood or other material providing spatial, structural rigidity) (6) with fixed plates (7) by using an adhesive or bolting through the provided holes (1). The dimensions of the lining (7), respectively: the width is equal to the width of the door, the length is equal to the length of the door, the depth (G) is from 15 mm to 50 mm. The attachment points of the door hinges (3) and the attachment point of the door handle (5) and the attachment point of the door lock (2) are made of identical material with the material of the door frame. Cavities (8) provide the required rigidity of the pads (7) to provide the necessary degree of compression in the specified parameters and restore the geometry of the pads.

Composition “FIG. 1 "location on the door leaf:

1. Bolt hole;

2. The installation location of the door handle, made of similar material to the door leaf;

3. The installation location of door hinges made of similar material to the door leaf;

4. Grooves to increase rigidity and increase the convenience of assembly and operation;

5. The door handle;

6. The door leaf;

7. A slip made of rubber or rubber;

8. Cavities in the overlay.

The composition of the lining "7" "Figure No. 2":

1. Bolt holes;

2. The installation location of the door handle, made of similar material to the door leaf;

3. The installation location of door hinges made of similar material to the door leaf;

4. Grooves to increase rigidity and increase the convenience of assembly and operation;

7. A slip from rubber or rubber;

8. Cavities in the overlay (7)

The example application of the proposed invention shows its usefulness in preventing injury to people. The application of the invention helps to reduce, including childhood injuries.

The alleged invention satisfies the criteria of novelty, since in determining the prior art no means have been found which have inherent features identical (that is, coinciding in the function performed by them and the form of these features) to all the features listed in the claims, including the purpose of the application.

This device has an inventive step, because it has not been identified technical solutions that have features that match the distinguishing features of this invention, and the popularity of the influence of distinctive features on the specified technical result is not established. The claimed technical solution can be implemented in industrial production, in the activities of many organizations, using well-known standard technical devices and equipment. This meets the criterion of "industrial applicability" presented to the invention.

This method has high economic feasibility and can be widely used due to low production costs, the widespread prevalence of door leafs, which reduces production costs calculated for each unit of production.

The invention provides high efficiency for the prevention of injuries.
