Description

The utility model relates to movable lock fasteners, more precisely to sliding fasteners, namely to zippers.

Below in the text, the “forward” direction will be the direction of movement of the slider when the zipper is closed, and “front” will refer to its side located in the direction of the closure.

Widely known are zippers containing two straps with locking elements and a slider serving to connect them, sometimes called a slider in the prior art, made in the form of a body with a Y-shaped channel, as well as a key ring loosely fastened to the slider [US 2065250, EP 1036517 B1, EP 1479306 B1, US 4409705, RU 178583].

The disadvantage of the known fasteners is that in the process of fastening them, it is possible to pinch the skin falling into the gap between the closing elements and the walls of the Y-shaped channel of the slider. This problem is very relevant for parents of young children who have not yet learned how to dress themselves, and pet owners. Overalls for dogs and cats are now widespread. The risk of pinching the pet's skin when fastening the zipper is quite high, because the animal often does not want to sit still and wait for it to be dressed. This forces the owners to fasten the zipper with sharp movements, not having time to make sure that there is no skin in the way of closing the zipper. And the skin of many breeds of dogs, especially decorative, short-haired or completely without wool, forms hanging folds. These breeds are most in need of clothing.

The purpose of the utility model is to exclude the possibility of pinching the skin of a person or animal into the channels of the slider when moving it along the braid with closing elements.

The technical result from the use of the proposed device consists in increasing the safety of the fastener by eliminating the possibility of pinching the skin in the gap between the channel of the slider and the closing elements.

The claimed result is achieved in that a security element made in the form of a plate installed in the front part of the slider with the possibility of folding back is additionally introduced into the known zipper, including the slider and the key fob.

In addition, the protective element contains an eye for a hinged connection with the slider.

In addition, the protective element is connected to the key fob by rods.

In addition, the security element is provided with a guide projection located on the side in contact with the locking elements.

Due to the introduction of a protective element made in the form of a plate installed in the front part of the slider, the safety of using the zipper is increased by preventing skin from getting into the gap between the channel of the slider and the closing elements.

Due to the fact that the security element contains a lug for pivoting with the slider, the security element can be folded backwards.

Due to the fact that the security element is installed with the possibility of folding back, it does not interfere with movement after the zipper is closed. If this possibility were not provided, after fastening, the security element would become an obstacle, reducing safety and being a source of damage (chafing) to the skin when moving the head or other parts of the body, depending on which item of clothing the zipper would be used on.

Due to the fact that the protective element is connected to the keychain with rods, the transfer of the protective element to the working position does not require additional movements and occurs simultaneously with the raising of the keychain when fastening, ensuring the safety of this process. The specificity of the process of fastening the zipper involves the obligatory lifting of the keychain. Upon completion of fastening, the keychain is lowered and at the same time folds back the protective element.

Due to the presence of a guiding protrusion on the security element, together with the front end of the security element, the task of maintaining the optimal trajectory of supply of the locking elements relative to the slider and maintaining the distance between the opposite locking elements at which it is still impossible to bite the skin at the time of their feeding into the Y-shaped channel is fulfilled. The likelihood of skin biting in the gap between the guiding protrusion on the security element and the locking elements is not great, but it does exist. Its minimization is ensured by the opening angle of the guide projection in the forward direction on the security element. Empirically, it was determined that this angle should have a value in the range of 30 ° -90 °. If its value is less than 30 °, then the likelihood of biting the skin will be very high. If its value exceeds 90 °, the supply of closing elements into the Y-shaped channel of the lock will be difficult or even impossible.

The essence of the utility model is illustrated by drawings.

FIG. 1 shows an embodiment of the device in which the key fob and the security element are connected by rods.

FIG. 2 shows the relative position of the zipper elements, highlighting the lead-in regions, the front of the security element and the Y-shaped channel.

The proposed zipper (Fig. 1) consists of a lock 1 with a key fob 2 and a security element 3. The security element 3 is a plate with a guide protrusion 4 on the inner side, acting as a guide for the locking elements 5 fixed to the braid 6.

In the described embodiment, the axle 7 of the key fob 2 and the axle 8 of the security element 3 pass through the lugs in the upper part of the lock 1, which ensures the hinged fastening of the key fob and the security element to the lock. The key fob and the security element are connected by rods 9. The traction connection ensures the synchronous movement of the key fob 2 and the security element 3. The Y-shaped channel 10 (Fig. 2) runs inside the lock /. Leading regions 11 are located at the front of the Y-shaped channel. The front part 12 of the protective element is located at the front end. The guide protrusion 4 of the security element has an opening angle of 13.

The proposed secure zipper works as follows. At the moment before the start of the zipper fastening, the keychain 2 is pressed against the lock / position. The security element 3 is in a folded back state. When fastening the zipper, the keychain 2, with the help of the fingers of the hand, is transferred to a position perpendicular to the plane of the braid 6, and the protective element 3, using the rods 9 connecting it to the keychain, is transferred from the folded back position to the working position (the plane of the protective element 3 is parallel to the plane of the braid 6). The guide protrusion 4, in this position, is located between the rows of locking elements 5 and does not allow them to approach each other.

When the slider 1 moves forward, the locking elements 5 move into the lead-in regions 11 of the Y-shaped channel along the side walls of the guide protrusion 4. If there is skin between the bands 6 with the locking elements 5, the protective element 3 with its front part 12 will prevent skin in the lead-in area 11 of the Y-shaped channel 10, thereby avoiding its "biting". The guide protrusion 4 provides a bite-safe distance between the rows of locking elements 5 at the front part 12 of the protective element 3.

At the end of the fastening of the fastener, the keychain 2 is transferred with fingers to a position parallel to the plane of the braid 6, and the rods 9 move the security element 3 to the folded back position.

Using a safe zipper can make the dressing procedure for babies safer and help to avoid injury to their skin. The same problem is solved by using a safe zipper in outdoor and domestic animal overalls, especially decorative breeds.
