Description

Lacing connector and lacing system comprising same

Technical Field

The utility model relates to the technical field of lacing, in particular to a lacing connector and a lacing system comprising the lacing connector.

Background

The shoelace is usually a belt for binding the inner and outer upper surfaces of the shoes, decorating the upper surfaces, adjusting the tightness of the shoes, etc. In tying a shoe upper with a lace, it is common to tie the upper with a bow tie or other fastener by crossing two portions of a lace through the eyelets and then tightening the lace to make a knot.

However, such knots are prone to automatic loosening or to becoming dead knots. If the shoelace is dead, the shoelace is difficult to be untied, thereby bringing great inconvenience to the life of people. If the shoelace is automatically loosened, once the shoelace is loosened, accidents are easy to happen. Particularly, when stepping on the shoelace in sports, the shoelace is easy to fall down, and the shoelace is relatively dangerous. And the shoelace is easy to loosen, and the shoelace needs to be tied repeatedly, so that the method is tedious and time-consuming.

The automatic fastening device solves the problems of manual shoelace tying, and the automatic fastening device of the rear-mounted shoelace tying is more and more popular with users due to low cost and easy replacement. For the post-loading fastening mechanism, the threading of one tie is complex, and the threading of two ties is more convenient and quick, but the problem that the free ends of the two ties are connected and fixed after the threading of the two ties exists, so that the direct knotting and fixing are not only attractive, but also easy to loosen.

Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

Example 1

Referring to fig. 1 to 5, a harness connector 10 according to an embodiment of the present utility model includes: a first connector housing 101 and a second connector housing 102, wherein a first end of the first connector housing 101 is provided with a first threading opening 1012, a second end of the first connector housing 101 is provided with a first connection opening 1011, a first threading channel 1013 is further provided in the first connector housing 101, the first threading channel 1013 communicates the first threading opening 1012 with the first connection opening 1011, a caliber of the first threading opening 1012 is smaller than a caliber of the first connection opening 1011, the first threading channel 1013 is used for threading a first free end 201 of a lace 20, and the first free end 201 of the lace 20 is fixed in the first threading channel 1013; the first end of the second connector housing 102 is provided with a second threading opening 1022, the second end of the second connector housing 102 is provided with a second connection opening 1021, a second threading channel 1023 is further provided in the second connector housing 102, the second threading channel 1023 enables the second threading opening 1022 and the second connection opening 1021 to be communicated with each other, the caliber of the second threading opening 1022 is smaller than that of the second connection opening 1021, the second threading channel 1023 is used for threading the second free end 202 of the tie 20, the second free end 202 of the tie 20 is fixed in the second threading channel 1023, and the second end of the first connector housing 101 is connected with the second end of the second connector housing 102 in a matching manner, so that two ends of the tie 20 are connected.

As shown in fig. 1 to 4, the connection method of the lace connector 10 and the lace 20: first, the first free end 201 and the second free end 202 of the tie are connected to the first connector housing 101 and the second connector housing 102, respectively; second,: the two connector housings 101, 102 are connected in a mating manner.

Specifically, the method of connecting the first free end 201 of the strap to the first connector housing 101 includes: the first free end 201 of the lace 20 is inserted into the first threading channel 1013 through the first threading opening 1012, is threaded out of the first connection opening 1011 through the first threading channel 1013, and is then knotted at the first free end 201 of the lace 20 near the tip, thereby forming a first knotting head 2011. Since the first connection opening 1011 has a larger caliber than the first threading opening 1012, the tie is pulled back and the first knot head 2011 is pulled back into the first threading channel 1013 through the first connection opening 1011. When the outer diameter of the first knotting head 2011 is smaller than the caliber of the first connection opening 1011 and larger than the caliber of the first threading opening 1012, the first knotting head 2011 may be caught at the first threading opening 1012, thereby connecting the first free end 201 of the tie 20 with the first connector housing 101, as shown in fig. 4.

Likewise, the second free end 202 is also connected to the second connector housing 102 in the same manner, wherein the second free end 202 is knotted proximate to the distal end to form a second knotted knot 2021, and the second knotted knot 2021 is clampable at the second threaded opening 1022 to thereby connect the second free end 202 of the harness to the second connector housing 102. In this way, the first connector housing 101 and the second connector housing 102 may be connected to the first free end 201 and the second free end 202 of the tie 20, respectively, and then the second end (one end of the first connection opening 1011) of the first connector housing 101 and the second end (one end of the second connection opening 1021) of the second connector housing 102 are cooperatively connected, thereby connecting both ends of the tie 20. The use of the lacing connector 10 makes the connection of the two ends of the lacing 20 simple and convenient, and the lacing connector 10 can protect and hide knotted knots at the two ends of the lacing 20, the connection is relatively firm, the lacing 20 is not easy to loosen, and the appearance is more attractive and integrated. It should be noted that in some embodiments, there may be various manners of mating connection between the first connector housing 101 and the second connector housing 102, such as a snap connection, a hook connection, a threaded connection, etc.

Preferably, the thickness of the lacing 20 is matched with the sizes of the first threading opening 1012 and the second threading opening 1022; and the caliber of the first threading opening 1012 is smaller than the caliber of the first connecting opening 1011, and the caliber of the second threading opening 1022 is smaller than the caliber of the second connecting opening 1021. As shown in fig. 4, the lace 20 can have a diameter slightly smaller than the apertures of the first and second threading openings 1012, 1022. Thus, by tying a knot at the ends of the two free ends of the tie 20, multiple knots are not required, and the connection is more convenient.

Referring to fig. 4 and 5, in one embodiment of the present utility model, the second end of the first threading channel 1013 near the lace connector is provided with an internal thread 10131, the second end of the second connector housing 102 is provided with a threaded connection portion, the first connection opening 1011 is located at the threaded connection portion, the threaded connection portion is provided with an external thread 1024, and the first connector housing 101 and the second connector housing 102 are fixedly connected with each other through the internal thread 10131 and the external thread 1024.
