Description

Technical field

The utility model can be used in the manufacture of jewelry and haberdashery. For jewelry that requires a reliable, convenient and aesthetically pleasing fastening in particular bracelets, neck chains, straps, etc. This application is about a lock for bracelets and jewelry. The design uses a lid and two hinged sashes, made in the form of hollow frames with a T-shaped protrusion and a groove, respectively, providing reliable mutual fixation in the articulated position, preventing uncontrolled opening. Unlocking and locking such a lock is carried out by combining the elements relative to each other with a subsequent change in the angle of fixation, the final fixation is carried out using the cover.

State of the art

The prior art applies locks designed to create a closed loop and have mechanical means of fixation, consisting of several elements. The main disadvantages of such locks are that when locking the lock they do not provide a secure fit and can spontaneously unfasten. Another disadvantage is the complexity of the structural implementation of these fixtures, the consequence of which is the complexity of replacing decorative elements and, accordingly, the complexity of their production. This drawback is eliminated in the locks, consisting of a minimum number of elements, the closing elements of which have a simple constructive solution, which reduces manufacturing costs. The purpose of the utility model is to improve well-known locks and develop a new original, reliable and easy-to-use lock design, reduce the number of elements, increase reliability by triple fixing when locking the lock.

[1] A spruggle-type lock is known which comprises two interlocking elements, in which a spring is used as the elastic element carrying out the movement of the latch. In the patent document RU 2396140 C1 B21F 35/00 (2006.01) The elastic properties of such springs are low, and with cyclic loading they have a sufficiently large shrinkage, the method of their production is not technologically advanced. Truss locks are not always suitable for certain jewelry and, moreover, this known lock does not have sufficient durability with a large number of compression cycles. In the event of a spring break at the sprengel (dog), it is only possible to replace the lock with a similar one, since a broken lock of this type cannot be repaired.

The closest in technical essence and the achieved technical result (prototype) is a box lock: Portal about jewelry and jewelry secrets [Electronic resource] // INFO@JUVELIRUM.RU: inform. - help portal. http://juveliram.ru Published: juvelirum Date: February 24, 2013 Access mode: - http://juveliram.ru/vidy-juvelimyh-izdelij/braslety/zastyozhki-dlya-brasletov-kakie-zamochki-luchshe/ - Zagl . from the screen (access date: 05/15/2017).

The box lock is based on the use of two halves - a box with a hole and a latch, which is a bar folded in half with notches at the end. The latch is inserted into the box and, thanks to the notches, is held inside. The design is strengthened with one or two locking loops. They increase reliability, but they themselves can cause the bracelet to cling to clothes. The disadvantage is that if the latch is damaged, in order to replace the fixation element, a sufficient number of manipulations with the fixation means must be done, which results in the inability to remove the latch from the hole without breakage, opening with a little more force leads to breakage, which is excluded in the proposed utility model. The box-shaped lock is difficult to manufacture, for safety, it is supplemented with a locking loop to prevent spontaneous opening, assembly is time-consuming, since the lock is made manually. The technical result of the proposed utility model can be expressed, in particular, mass production by vacuum casting, which simplifies the manufacture, as a result of which the cost of the finished product decreases.
