Description

The present invention relates to vehicles, in particular to the side doors of automobiles, and can be used in their manufacture.

The side part of the car body contains doorways, in which there are doors designed for entering and exiting the car and loading and unloading goods. External handles are directly affected by atmospheric phenomena and bear traces of them in the form of dust, dirt and moisture, so when opening and closing doors from the outside, your hands often get dirty.

Some designs of passenger car side doors are shown in patents WO 2011054826 (A1) of 05/12/2011, B60J 5/04; KR 20120102417 (A) from 09/18/2012, B60J 5/00, B60J 5/04; WO 2012145849 (A1) dated 01/01/2012, B60J 5/04, B60R 21/00, B62D 25/00, B62D 25/02. The closest in technical essence to the claimed invention is patent RU 2466253 C1 dated 10.11.2012, ЕВВ 65/12, which presents the design of the outer handle of the side door of a car, recessed in the closed position, flush with the door surface, which does not allow its inner surface to get dirty. To open and close the door, the specified handle is pushed out under the influence of the central lock of the car. The disadvantage of these designs is the difficulty in opening the door from the outside, if the hands are occupied, for example, by a sleeping child.

The aim of the invention is to develop a method of opening a side door of a car from the outside without using hands.

The solution of the technical problem is provided by the fact that the outer handle of the side car door moves to the threshold and becomes a pedal. In order to avoid unauthorized opening of the door by foreign objects, for example, when the car is skidded, the pedal is installed in the recess of the threshold with which the doorway is mating with its lower part. Outside, the recesses are closed with decorative covers, similar to filling hatches.

The essence of the technical solution is illustrated by a description of an example of its preferred embodiment with reference to the accompanying drawings. The same item numbers are used throughout the description and in all drawings to refer to the same components and parts. Figure 1 presents these recesses 1 and 2, respectively, for the front and rear doors. To open the door, you need to press the toe of the shoe soles on the pedal 3 down (figure 2). The opposite end of the lever 4, on which it is mounted, rises to the inner surface of the upper part of the threshold and pushes the rod 5 into the inner cavity of the door, acting on the door lock. The lock is unlocked, the rod 5 is fixed in the raised position, the door is pushed out of the doorway under the influence of a spring, and it can be opened by holding onto a clean internal surface.

To completely exclude hands from the process of opening a side door, you need to change the location of the door hinges on which it is pivotally mounted in the doorway of one of its sides. In the doorway, the door is most often mounted on two hinges located vertically one above the other, so the axis of rotation of the door is located vertically, and the door at any opening angle is in equilibrium. It is enough to shift the upper hinge 6 from vertical to the outside of the car relative to the lower 7, as shown in Fig. 3, so that the door, after unlocking the corresponding door lock, opens independently by gravity.

When opening the door from the inside of the car, the stem 5 is removed into the inner cavity of the door by acting on the inner handle. Closing the automobile side door of the claimed design is carried out in the usual manner. When the door is slammed, the latch releases the stem 5, which lowers onto the lever 4, preparing the device for a new door opening.

It is possible to use an electric button instead of the pedal, when pressed, its contact is closed in the unlocking solenoid circuit. The button in this case for protection against moisture and dust is located in a protective rubber cover.

Thus, the outer surface of the side doors of the car is freed from auxiliary parts, only the larva 8 of the lock on the front door remains.

The essence of the claimed invention lies in the fact that a method and device for unlocking a side car door from the outside without using hands by pressing a pedal located in the threshold unlocking the lock, after which the door opens independently under the action of its mass by tilting the axis of rotation from the vertical to the outside of the car, is developed.

The technical result of the claimed invention is to increase the consumer qualities of the car by protecting the hands of the driver and passengers from dust and dirt when opening the side door from the outside, as well as the ability to open it without using hands, for example, with busy hands.

The specified technical result is achieved due to the fact that a method and device for unlocking a side car door from the outside without using hands by pressing a pedal located on the threshold of the unlocking lock, after which the door opens independently under the action of its mass due to the inclination of the axis of rotation from the vertical to the outside of the car, has been developed.

The specified layout of the side door increases the comfort of passenger vehicles, ease of use and consumer qualities of the car. Improving the consumer qualities of the car lies in the fact that the hands of the driver and passengers do not get dirty when opening the side doors from the outside, as well as due to the possibility of opening the door with busy hands.

The protection of the driver’s and passengers ’hands from dust and dirt when opening the side doors from the outside consists in the development of a side automobile door designed to be unlocked by pressing the foot located on the threshold of the pedal, after which the door opens independently under the action of its mass due to the inclination of the axis of rotation from the vertical to the outside a car.

New significant features of the claimed invention are:

- improving the consumer qualities of the car;

- protection of the hands of the driver or passengers from dust and dirt when opening the side doors of the car;

- use for unlocking the side door of the pedal located in the threshold of the car;

- the ability to open the door with busy hands;

- independent opening of the door under the action of its mass due to the inclination of its axis of rotation from the vertical to the outside of the car.
