Description

shoe reel

technical field

The utility model relates to a cord reel, in particular to a shoe cord reel suitable for shoes.

Background technique

Although it is not difficult to tie the laces, the work of tying the laces can only be completed by putting a slipknot on the laces after the laces pass through the loops of the shoes and boots. This tying of the laces becomes a redundant and time-wasting action, especially for For those who are not familiar with knotting, in addition to the safety problem that the lace is easy to loosen, it will also affect the overall appearance of the shoes and boots.

Therefore, there is a Chinese Taiwan Announcement No. 1252741 tethering device patent prior case in response to it. Looking at this patent case, it can indeed improve the convenience of fastening the lacing, but it is still not optimal. There are three reasons:

1. When fastening the laces, the user has to pull the two laces up with one hand at the same time, while the other hand presses down the lace device, so that the laces can be fastened. This mode of operation is still troublesome, and For young children or people with low intelligence, it is really difficult to fasten.

2. Its lacing head is not fixed on the fastening device, so when the lacing is loosened, the tying device and the lacing will be loosened if you are not careful, and it is quite difficult to make the lacing re-enter the tying device. time consuming.

3. The frenulum is directly clamped by the ratchet teeth, which will damage the periphery of the frenulum, resulting in a significant reduction in the life of the frenulum for repeated use.

The reason is that the designer has successfully created the utility model through many tests and designs in view of the shortcomings of the conventional tether device, so as to thoroughly solve the existing problems of the conventional use.

The screw hole 23 intersects with the tie hole 22, so that The head of the tether 70 passes through the guide hole 17 and the retracting area 21 in order to pass through the tie hole 22. The screw 230 locks the head of the tether 70 to the retracting shaft 20, and one end of the retracting shaft 20 is coaxially provided with a protrusion The pivoting column 24 at the opening end of the bearing hole 11 and the other end are coaxially recessed with an internal gear 25 smaller than the through hole 12 and connected to each other;

A cover 30 is provided with the female thread 31 of the male thread section 15 on the back of the cylinder seat 10 to close the bearing hole 11. The inner end surface of the cover 30 is recessed with a blind hole for the pivoting post 24 to pivot. 32, to strengthen the rotation positioning of the take-up shaft 20 on the cylinder base 10;

A restriction cylinder 40, one end of its axis is concavely provided with a restriction hole 41 with a certain depth and larger than the through hole 12, and the other shaft end is provided with a perforation hole 42 with a smaller diameter. The female thread 43 of the front male thread section 14 is then provided with ratchets 44 protrudingly at positions 120 degrees apart from the restricting holes 41, and the restricting cylinder 40 is provided with a forming flow channel 45 at a position opposite to the ratchets 44 for forming and manufacturing Out ratchet 44;

A drive shaft 50 has a ratchet 51 meshing with the ratchet 44, an external gear 52 meshing with the internal gear 25, a pin shaft 53 that protrudes through the hole 42 and pivots with the hole 42, and the ratchet 51 is thicker than the limiting hole 41. The depth is small, so that the bolt shaft 53 protruding from the through hole 42 can be pulled forward and backward with a margin, and this distance is enough to make the external gear 52 escape from the internal gear 25; and

A control cylinder 60, one end of its axis is concavely provided with a holding hole 61 that can be slidably sleeved on the front half of the limiting cylinder 40, and the inner end of the holding hole 61 is also concavely provided with a bolt hole 62 for the coupling of the bolt shaft 53, and the control cylinder 60, the other end of the shaft is concavely provided with a cap hole 63, which is covered and closed with a decorative cover 64, and a bolt 65 is threaded in the cap hole 63, and this bolt 65 can be screwed to the bolt shaft 53, so that the control The barrel 60 is integrated with the drive shaft 50 so that the control barrel 60 can pull the drive shaft 50 back and forth.

As shown in Figures 9 to 11, when the utility model is implemented, the cylinder base 10, the take-up shaft 20, the restraining cylinder 40 and the drive shaft 50 are sequentially assembled, and then the cylinder base 10 is fixed on the shoe. The position of the tongue is such that the limiting cylinder 40 and the driving shaft 50 protrude from the tongue, and then the two laces 70 are respectively inserted into the corresponding guide holes 17, and then passed through the retracting area 21 and the tie hole 22 into the screw hole 23 for The supply screw 230 locks the head of the lace 70 to the retracting shaft 20, and then slides the control cylinder 60 on the front half of the restricting cylinder 40, and locks the bolt shaft 53 with the bolt 65, thus completing the assembly procedure.

As shown in Figure 10, when the user wants to fasten the shoe strap 70, due to the engagement of the ratchet 51 and the ratchet 44, the control cylinder 60 can only be rotated in one direction, so that the external gear 52 of the drive shaft 50 drives the coil. The inner gear 25 of the retracting shaft 20 enables the retracting shaft 20 to retract the shoe lace 70 in the retracting area 21, so as to achieve the function of fastening the shoe lace 70.

As shown in Figure 11, when the user wants to loosen the shoe strap 70, he only needs to pull the control cylinder 60 forward to make the ratchet 51 slide along the ratchet 44 limit, so that the drive shaft 50 and the external gear 52 simultaneously The inner gear 25 of the take-up shaft 20 is pulled out to the restricting hole 41, so that the take-up shaft 20 can be released, and the user can directly pull the lace 70 of the shoe to loosen, so that the user can take off the shoe.

Therefore, the overall operation of the utility model can be completed only by rotating or pulling the control cylinder 60 with one hand, and this simple mode can indeed be used to operate the loosening or tightening of the tie belt 70, so as to overcome the above-mentioned patents. It is troublesome and inconvenient to operate with both hands, and it can be easily used by young children or people with low intelligence.

Furthermore, the head of the tether 70 of the present invention is directly locked on the take-up shaft 20, so when the tether 70 is loosened, there is no need to carefully pull it, because the tether 70 of the present invention is completely free from the trouble of getting loose and reinserting. .

Secondly, the tether 70 of the present invention is retracted on the take-up shaft 20 , so the outer periphery of the tether 70 will not be damaged, and thus the service life of the tether 70 can be maintained.

The above is only a preferred embodiment of the present utility model, and cannot limit the scope of creation of the present utility model with it. Generally, all equal changes and modifications made according to the patent scope of the utility model should still belong to the utility model. within the scope covered.
