Description

The utility model relates to storage devices and can be used to store keys.

A pocket case is known (patent US1414798A, publ. 05/02/1922), the body of which is a side wall connected along the long side. On one side of the cover there is an opening between the side walls for placing a belt holding the keys in it. On the opposite side of the opening, the side walls are not connected, so that a receiving opening is formed through which keys can be placed between the side walls. On the side walls on the side of the receiving opening, there are two parts of the latch in the form of a button, designed to block the receiving opening of the said housing in the closed state. When opening the receiving hole, the keys are removed from the case, remaining attached to the belt. If you want to store the keys in the case, then you need to pull the strap from the side of the strap hole until the keys are between the side walls. After that, you need to block the receiving hole by connecting and squeezing the two parts of the latch (reciprocal and receiving parts of the button).

The disadvantage of this device is that it is difficult to remove the keys from the case if the user has the opportunity to use only one hand for this.

Known wallet (patent DE1194540B, publ. 06/10/1965), designed to store coins and keys. The wallet has a body consisting of two outer walls and one inner partition, forming two pockets, one of which is designed to store keys, and the second - to store coins. The peculiarity of the wallet is that in the part of the walls in which they are not connected, there are two springy inserts. When you press the sides of the case, the spring inserts bend, opening the receiving hole for coins or keys.

The disadvantage of this device is that the keys are not fixed in it and can fall out if the user has the opportunity to use only one hand to extract the keys.

The prototype is a key case (patent US3119429A, publ. 01/28/1964), which is presented in the form of a housing having an end wall and opposite flat walls, which are made as a single unit with the side walls. The end wall has a slot. Through the slot inside the case, you can place the keys on the chain. The keys are held inside the case due to the fact that they are squeezed by the flat and side walls of the case. When squeezing the side walls with your fingers, the slot in the end wall acquires a rounded shape due to the elasticity of the material from which the cover is made: rubber, rubber. As a result, the keys are released from the case. The keys are secured inside the case on a chain.

The disadvantage of this device is that it is laborious to manufacture, since specialized equipment, special raw materials and strict adherence to the manufacturing technology of the product are required to create a single body structure made of elastic material.

The disadvantage is also that, firstly, the slot in the end wall does not close completely and the key chain may at any time be outside the case. Secondly, some effort is required to remove the keys and the chain on which they are held inside the case. The combination of these shortcomings leads to the fact that the chain can at any time be outside the case, for example, when carried in a bag, and, catching on foreign objects, release the keys from the case.

In addition, the disadvantage is also that the slot in the end wall does not close completely at the moment when nothing is squeezing the side walls. That is, the keys can fall out of the case without the user's desire.

The technical result of the claimed solution is the expansion of the arsenal of technical means designed for storing and carrying keys, providing the ability to extract the keys with one hand and at the same time preventing the keys from falling out of the means for carrying and storing. In this patent, the falling out of keys refers to cases where the keys can be accidentally removed from the case when carrying (for example, due to a loosely closed case, the keys in the bag can fall out of it) or cases when the keys can be separated from it when opening the case with one hand (for example, fall to the floor).

When using the claimed solution, a useful effect is achieved - provided that the keys are stored in the key holder, they do not damage the phone and other items when they are together with them in a bag or pocket.

The technical result is achieved due to the fact that the key case contains:

1. two walls connected on all sides except one,

2. hole at the junction of the walls,

3. a flexible element holding the keys, fixed in the hole with the possibility of movement,

4. the receiving hole formed by the non-connected sides of the walls,

5. at least two elastic inserts fixed along the non-connected sides of the walls,

6. moreover, at least one magnet is fixed along at least two elastic inserts.

The presence of connected walls provides the possibility of fixing the keys inside the case. The hole at the junction of the walls allows you to move the flexible element holding the keys in such a way that when the case is opened with one hand and the keys are removed from it, the latter remain connected to the case through the flexible element holding the keys, do not fall to the floor and are not lost. The movement of the key retaining flex also allows keys to be placed within the case effortlessly in one motion. Elastic inserts attached to the walls along the non-connected sides of the walls make it possible to tightly close the receiving opening, which prevents the keys from falling out when they are transported in a case.

The essence of the claimed solution is illustrated by drawings. In FIG. 1 shows a general view of the key case at the moment when the keys are placed inside it. In FIG. 2 shows a general view of the key case at the moment when the keys are removed from it.

In one embodiment, the key case consists of two walls 1 connected to each other along the sides 2 and on one end side 3. In the end side 3, at the junction of the walls 1, there is an opening 4, in which a flexible element 5 holding the keys is placed. On the opposite side from the end side 3 there is a receiving opening 6 formed by the non-connected sides of the walls 1. Inserts 7 are placed along the receiving opening 6, forming a closing device.

To use the cover, the flexible element holding the keys 5 is withdrawn for the entire possible length through the receiving opening 6. The flexible element holding the keys 5 is placed in the opening 4 in such a way that it can move freely through the opening 4, but could not be completely removed from the opening. 4 and separated from the case. This can be achieved, for example, by thickening the end of the key-retaining flexible element 5. This is also achieved by fixing the keys at the extracted end of the key-retaining flexible element 5. When pressing on the side parts of the inserts 7 forming the closing device, the receiving opening 6 expands due to the fact that the inserts 7 bend in opposite directions. If you pull at this moment the flexible element 5 on the opposite side of the keys, then the keys will be placed between the walls 1. After that, you can stop pressing on the side parts of the inserts 7 and the receiving hole 6 will close.

The walls can be in the form of a triangle, rectangle, square or trapezoid. The walls may have an irregular shape, provided that the walls have a smooth, straight edge on the side of the receiving opening. The walls can be made from a single web of material connected on the sides 2.

The walls can be made of any material capable of bending, as is necessary for the use of the proposed closing device, and strong enough not to be damaged when keys are carried in it. For example, it can be fabric, leather, polymeric materials.

The flexible element holding the keys can be made in the form of a cord, for example, of a polymeric material or other fiber, in the form of a strap, for example, of leather, or in the form of a chain. Any of the listed embodiments of the retaining element provides the ability to fix keys on it, is strong enough to withstand the weight of the keys when they are removed from the case, and durable enough to allow the keys to be repeatedly placed inside the case with it.

The inserts forming the closing device are fixed on the walls along the receiving opening. They can be placed in a groove formed by a folded strip of material from which the wall is made. The inserts may also be attached to the walls along the receiving opening with adhesive or otherwise. The above methods of fixation ensure the durability of the use of the case and allow you to store and carry the keys, securely fixing them in the case without the risk that the keys will fall out of it.

The inserts forming the closing device are made in the form of plates or plates with a cylindrical bend, in which the middle plane of the plate is curved along the cylindrical surface. The cylindrical bend increases the elasticity of the plate and allows the closing device to close more tightly, preventing the keys from falling out.

Inserts can be made of any elastic dense material, such as plastic or thin metal. The use of such a material ensures the proper functioning of the closing device and the durability of its operation.

The presence of magnets along at least two elastic inserts allows you to securely fix the keys in the case without the risk that the keys will fall out of it. There must be at least two magnets so that they can show their properties and securely close the case. The number of magnets can be increased, for example, there can be four, to provide a greater degree of fixation.

The applicant tested the claimed technical solution. During testing, it was found that the claimed solution provides the ability to remove the keys from it with one hand and at the same time prevents the keys from falling out of the key case during their carrying and storage. That is, when using the claimed solution, the arsenal of technical means intended for storing and carrying keys is expanding.
