    Description: TECHNICAL FIELD [0001] The present invention relates to a double-lock loop assembly for fastening two belts together. In particular, the invention relates to a loop assembly in which both belts can be adjusted and which can be opened easily. 2. State of the art [0002] Buckles for fastening together two belts are often used on belts, backpacks and luggage. It is desirable that the belts can be adjusted and that the buckle can be disengaged without losing the positioning of the belts. It is also important that the buckle can be completely disengaged but does not disengage inadvertently when it experiences sudden lateral pressure.
    [0003] A loop that achieves these goals is disclosed in Korean Patent Application Publication No. 10-2012-0 121 956. In this application, a main loop portion is connected to a belt. This main part of the loop can be locked on a locking device connected to a second belt. The locking device is attached to the main loop portion by means of hinge bumpers that lock into slots on the main body, and by additional protuberances on the main body that lock into slots on the locking device. . The buckle can only be disengaged by pivoting the latch up and away from the main body and sliding the latch behind the main body.
    Although this loop is effective to lock the two parts together, it requires that the two parts are snapped together with the additional protuberances to prevent the two parts from separating. This often requires the use of two hands, as the parts pivot relative to each other around the hinge bumpers. It would be desirable to create a loop having a small number of projecting portions, to limit the wear and risk of breakage of the loop, and to develop a loop that can be locked simply and easily. SUMMARY OF THE INVENTION An object of the invention is therefore to provide a loop having a single simple locking mechanism, in which the parts can connect to each other easily, and which does not may inadvertently separate.
    These objects are achieved by a loop assembly having a base portion and a locking portion adapted to connect to the base portion. The base portion has an upper surface, a lower surface, side walls, a belt attachment bar positioned between the side walls, and an inner opening disposed between the side walls. The inner opening has a width that extends between the side walls and a length perpendicular to the width.
    The locking portion has opposite side walls, a belt attachment bar, and a protrusion that extends outwardly from each of the side walls. The locking portion has a width that extends from one of the side walls to the other and a length that extends perpendicular to the width of the locking portion. The length of the locking portion is greater than the length of the opening in the base portion and the width of the opening at its widest point is greater than the width of the locking portion at its point the wider. In this way, the locking portion can be slid entirely through the opening of the base portion by positioning the locking portion perpendicular to the base portion and sliding the locking portion from below the base portion to the base portion. the top of the base portion. The locking portion can then be connected to the base portion by positioning the locking portion parallel to the base portion, so that the locking portion can no longer pass through the opening, since the length of the portion of base is larger than the length of the opening. This creates a first lock level, where the lock portion can not be inadvertently separated from the base portion.
    The side walls of the base portion each have a slot arranged to receive the protuberances of the locking portion when the locking portion is placed on an upper surface of the base portion. In this way, when the locking portion extends parallel to the upper face of the base portion, the protuberances can snap into the slots to maintain the locking portion to the base portion. This creates a second level of locking, to ensure that the locking portion can not disengage from the base portion, even when there is no tension on the belts connected to the base portion and the locking portion. .
    Preferably, the side walls of the base portion have an inner contour which corresponds to the shape of an outer contour of the locking portion, so that the locking portion can sit within the side walls of the base portion when the base portion and the locking portion are locked to one another. This makes it very easy to connect the base portion and the locking portion since the locking portion is automatically forced into a correct orientation by being snap-fitted. The two portions can thus be easily locked together using one hand only, either to lock the locking portion directly or to pull on a belt connected to the locking portion, as will be explained in more detail below.
    In one embodiment, the belt attachment bar of the base portion is disposed at one end of the base portion and the belt attachment bar of the locking portion is disposed through the middle of the base portion. the locking portion extending between the side walls of the locking portion. The locking portion is preferably configured with a cavity between the side walls, and the belt fastener passes through the cavity. In this manner, the belt can extend upward and around the belt attachment bar, with the strands extending through the cavity on either side of the belt attachment bar.
    In another embodiment, there are two additional protuberances each placed on the inside of the side walls of the locking portion adjacent to the belt attachment bar. Insertion of the belt between the belt attachment bar and the additional protuberances causes the belt to bear against the protuberances and to be held in place during manufacturing and assembly of the buckle portion. By pressing on the marginal zones of the belts, the protuberances cause the creation of a "belly" in a median zone of the belt, which is arched away from the belt attachment bar. This arched configuration prevents slippage of the belt during assembly. In addition, the protuberances allow for easier assembly since the belt can be sewn before insertion into the locking portion due to the additional space created by the absence of a narrower slot or a belt attachment bar. additional.
    In use, the belt is disposed on the belt attachment bar of the locking portion, so that when the locking portion is connected to the base portion, the strands of the belt extend through the cavity of the base portion. In this manner, pulling the belt ends in a direction parallel to the upper and lower surfaces of the base portion and locking portion causes engagement of the protuberances in the slots and locking of the locking portion to the portion of based. By pulling on the belts, the locking portion is constrained downward on the base portion, because the belt on the locking portion also extends through the base portion. Thus, a tension on the belts causes an automatic locking of the locking portion in the base portion and prevents inadvertent disengagement. When the tension on the belts is completely relaxed, the locking portion is easily disengaged from the base portion. To disengage the locking portion from the base portion, the locking portion must be pivoted to be substantially perpendicular to the base portion so that it can pass through the opening in the base portion.
    In another embodiment, the base portion has a notch on an end opposite the end with the belt attachment bar. This notch allows the locking portion to overhang the base portion when the two portions are locked together, and allows the locking portion to easily disengage from the base portion by pushing upwardly on the locking portion.
    The present invention is an improvement over loops of the prior art since it is easy to engage and disengage but absolutely prevents disengagement inadvertently, both under tension and when the tension is released. Straps can easily be added and sewn onto the buckle portions while the portions are attached to each other, thereby making manufacture and assembly easier. In addition, since there are no large protruding parts, the loop portions can not easily be broken. 4.

DETAILED DESCRIPTION OF THE INVENTION [0017] Referring now more in detail to the drawings, FIGS. 1 and 1A show the loop assembly 1 according to the invention in an assembled state. The loop assembly 1 comprises a base portion 10 and a locking portion 20, which engages an upper surface of the base portion 10. FIGS. 2 and 2A show the base portion 10, which has an upper surface 11, a lower surface 12 and two raised side walls 13, 14. Between the side walls 13, 14 is an opening 15 which has a width w 1 and a length h. At the end of the base portion 10 is a belt attachment bar 16 for attaching a belt to the base portion 10.
    FIG. 3 shows the locking portion 20, which has an upper surface 21, a lower surface, side walls 25,26, a cavity 23 between the side walls 25,26 and a belt attachment bar placed through the cavity 23 between the side walls 25, 26. On the outside of the side walls 25, 26 are protuberances 27, 28. The locking portion 20 has a width w2 and a length l2.
    The width w · of the opening 15 in the base portion 10 is greater than the width w2 of the locking portion 20, and the length 12 of the locking portion 20 is greater than the length h. of the opening 15. This allows the locking portion 20 to be integrally inserted through the opening 15 of the base portion 10 when the locking portion 20 is placed substantially perpendicular to the base portion 10 but prevents the locking portion 20 to pass through the opening 15 when the locking portion 20 is disposed in parallel with the upper surface of the base portion 10.
    Figs. 4 to 8 show the process for connecting the base portion 10 to the locking portion 20. The base portion 10 is connected to the belt 30, which is sewn around the belt attachment bar 16. The locking portion 20 is connected to the belt 40, which is threaded around the belt attachment bar 24. The loop assembly 1 according to the invention is used to connect two belts together in a way that prevents inadvertent disengagement under tension but however, it is easy to engage and disengage. Fig. 4 shows the two portions 10, 20 before their engagement. To connect the base portion 10 and the locking portion 20, the locking portion 20 is inserted through the opening 15 from the lower surface 12 of the base portion 10, as shown in FIG. 5. The locking portion 20 slides easily through the opening 15, since the width w, of the opening 15 is larger than the width w2 of the locking portion 20, as explained above.
    Once the locking portion 20 has completely passed through the base portion 10 so as to lie above the upper surface 11 of the base portion 10 (as shown in Fig. 6), the locking portion 20 can be easily and firmly connected to the base portion 10 simply by pulling on the belts 30 and 40. The belt 40 is fully extended through both the locking portion 20 and the base portion 10, while the belt 30 contacts only the base portion 10.
    By pulling on the belts 30 and 40, the locking portion 20 is constrained downwardly on the upper surface 11 of the base portion 10, as shown in FIGS. 7 and 8. Insofar as the locking portion 20 has a length 12 which is greater than the length h of the opening 15, the locking portion 20 can not pass through the opening 15 while the two portions 10, 20 are arranged in parallel with each other. This creates a first level of locking, where the locking portion 20 can not inadvertently be disengaged from the base portion 10.
    In addition to forcing the two portions together, the fact of pulling on the belts 30, 40 also causes the protuberances 27, 28 on the locking portion 20 to snap into the slots 18, 19 of the base portion. 10, as illustrated in FIG. 9. This creates a second level of locking between the base portion 10 and the locking portion 20. The slots 18, 19 are disposed on an inner surface of the side walls 13, 14 of the base portion 10 and are positioned to be located directly adjacent to the protuberances 27, 28 when the locking portion 20 is placed above the base portion 10. The interaction of the protuberances 27, 28 with the slots 18, 19 prevents the locking portion 20 from disengaging from the base portion 10, even when the belts are released. To open the loop assembly 1, the locking portion 20 must be lifted out of the base portion 10 until the protuberances 27, 28 are ejected out of the slots 18, 19. Then, the locking portion can to be rotated
