The present disclosure claims the priority to the Chinese patent application with the filing number CN201811380427.3, filed on Nov. 20, 2018 with the Chinese Patent Office, and entitled “Rope Adjusting Device and Article Having Rope Adjusting Device”, the contents of which are incorporated herein by reference in entirety.
The present disclosure relates to the technical field of articles for daily use, in particular to a rope adjusting device and an article having the rope adjusting device.
Products such as shoes, clothes and medical protective gear are provided with ropes, and the purpose of fixing the products is achieved by adjusting tightness of the rope (or rope belt).
At present, one needs to pull two ends of the rope by two hands, respectively, to realize adjustment of tightness, and then fix the rope by knotting.
The knotting needs to be completed by two hands, and the tightness degree of knotting is hard to ensure. When going out, due to movement and other reasons, the rope may become loose, and at this moment, the rope needs to be knotted again.
The knotting is relatively time-consuming, and as to shoelace, only when one bends down, can the knotting operation be performed. However, once encountering a crowded situation, the operation of tying cannot be performed at all, which may cause drop-out of the shoe when the heelpiece is stepped on.

Referring to
As shown in
As the driving portion 4 and the linkage portion 5 are relatively fixed, the linkage portion 5 will also be rotated synchronously when the driving portion 4 is rotated with the adjusting part 1. Moreover, as the adjusting part 1 can be rotated with respect to the mounting base 2, axes of rotation of both the driving portion 4 and the linkage portion 5 are also collinear.
As shown in
The rope winding part 3 is rotatably connected to the mounting base 2.
As shown in
By rotating the adjusting part 1, a user enables the driving portion 4 on the adjusting part 1 to drive the driven portion 7 on the rope winding part 3, so as to control the rotation of the rope winding part 3, but as the rotation restricting portion 6 restricts the rotational direction of the linkage portion 5, the adjusting part 1 can only rotate towards one direction, thereby the rope can be prevented from becoming loose.
In the present embodiment, the adjusting part 1 further includes a housing 8, wherein the driving portion 4 and the linkage portion 5 are both provided inside the housing 8.
The three, namely, the housing 8, the driving portion 4 and the linkage portion 5, may be integrally molded. Specifically, plastic may be selected as a raw material, and the housing 8, the driving portion 4 and the linkage portion 5 are integrally molded by an injection molding process. In other specific embodiments, a process such as die casting may also be used.
As shown in
In the present embodiment, the adjusting part 1 and the mounting base 2 are rotatably connected. Specifically, on the housing 8, an inner wall of an inner bore configured to arrange the driving portion 4 and the linkage portion 5 may be provided with a plurality of buckles 10 in a manner of annular array with respect to an axial line of the driving portion 4, and correspondingly, the mounting base 2 may be provided with a brim (or convex edge) 11 corresponding to the buckles 10. When fastening the buckles 10 to the brim 11, the relative movement between the adjusting part 1 and the mounting base 2 is restricted by the action of the buckles 10 and the brim 11, so that the adjusting part 1 and the mounting base 2 can only rotate relative to each other, without occurrence of disengagement.
In the present embodiment, an outer gear ring may be selected as the driving portion 4, an inner ratchet ring may be selected as the linkage portion 5, an inner gear ring may be selected as the driven portion 7, and a pawl may be selected as the rotation restricting portion 6.
Specifically, a plurality of pawls may be provided and distributed in a manner of annular array about an axis of rotation of the rotation restricting portion 6. By increasing the number of pawls, the restricting effect of the pawls on the inner ratchet ring can be improved and enhanced, and meanwhile, the force can be distributed on the respective pawls, thereby preventing a single pawl from breaking due to uneven force.
The outer gear ring is meshed with the inner gear ring, so as to realize transmission connection therebetween; the inner ratchet ring cooperates with the pawls, and the steering of the inner ratchet ring can be controlled by the pawls, so that the inner ratchet ring can only rotate towards a single direction, thereby also restricting the rotational direction of the adjusting part 1. Meanwhile, due to the restriction of the pawls, as long as the pawls abut against the inner ratchet ring, the adjusting part 1 cannot rotate reversely to loosen the rope.
In the present embodiment, the radius of addendum circle of the outer gear ring is smaller than the radius of addendum circle of the inner ratchet ring.
In the above, in other specific embodiments, an inner gear ring may be chosen as the driving portion 4, and an outer gear ring corresponding thereto may be chosen as the driven portion 7.
As shown in
The insertion part 12 is inserted into and slidably connected to the insertion hole 13, and meanwhile, the insertion part 12 is further rotatably connected to the insertion hole 13 all the time.
In the above, the linkage portion 5 is combined with or separated from the rotation restricting portion 6 through relative sliding between the insertion part 12 and the insertion hole 13, that is, realizing combination and separation between the inner ratchet ring and pawls in the present embodiment. When the linkage portion 5 is combined with the rotation restricting portion 6, the adjusting part 1 can only rotate towards a single direction; when the linkage portion 5 is separated from the rotation restricting portion 6, as being free of restriction of the rotation restricting portion 6, the adjusting part 1 can rotate in two directions, meanwhile, the rope is in a free state, and can be elongated or shortened freely with the rotation of the rope winding part 3, so that the tightness degree of the rope can be adjusted more conveniently.
In the present embodiment, the insertion part 12 may include several elastic plugs 14, wherein the plug 14 are provided with a metal spring sheet 15 configured to improve the strength. Specifically, two plugs 14 may be provided, and the metal spring sheet 15 may be mounted between the two plugs.
Sliding and rotating actions need to be performed for inserting the plugs 14 into the insertion hole 13, so that damage, breakage and other situations easily occur, while by mounting the metal spring sheet 15 between the two plugs 14, the strength and the service life of the insertion part 12 can be effectively improved.
As shown in
During use, the linkage portion 5 needs to be combined with the rotation restricting portion 6 most of the time, so as to control the tightness degree of the rope, and only when the rope needs to be loosened, the linkage portion 5 needs to be separated from the rotation restricting portion 6. In order to prevent the linkage portion 5 from being separated from the rotation restricting portion 6 to loose the rope due to vibration, swinging or other situation, a protrusions may be provided on an outer wall of the plugs 14, and correspondingly, limiting grooves corresponding to the protrusions are provided in the insertion hole 13, then relative sliding between the insertion part 12 and the insertion hole 13 is prevented through cooperation between the protrusion and the limiting groove.
When the protrusion is located in the limiting groove, the linkage portion 5 and the rotation restricting portion 6 are in a combined state. When the adjusting part 1 is pulled with an external force and the protrusion is slid out of the limiting groove, the linkage portion 5 and the rotation restricting portion 6 will be separated from each other; thereafter, when the linkage portion 5 and the rotation restricting portion 6 need to be combined again, it is only necessary to press the housing cover 9 of the adjusting part 1 to make the protrusion to slide into the limiting groove.
The rope winding part 3 is rotated to make the rope to wind thereon, so as to control the length of the rope. As shown in
Referring to
Due to the existence of the limiting buckles 22, the limiting buckles 22 affect the installation and disassembly of the rope winding part 3 to a certain extent. As shown in
When mounting the three, namely, the adjusting part 1, the mounting base 2 and the rope winding part 3, the adjusting part 1 may be first connected to the mounting base 2, and then the rope winding part 3 is placed in the mounting hole 16, and the insertion part 12 is inserted into the insertion hole 13.
In order to facilitate the mounting of the rope on the rope adjusting device, a side wall of the mounting base 2 may be provided with several rope inlet holes 17 in communication with the mounting hole 16. In the above, in the present embodiment, the number of the rope inlet holes 17 may be set to two or three and so on.
As shown in
After passing through the rope inlet hole 17 and the mounting hole 16 in sequence, a front end of the rope may pass through the rope threading hole 19, and then the front end of the rope is fixed, and then the adjusting part 1 is rotated, and the rope winding part 3 is rotated under the action of the driving portion 4 and the driven portion 7, so as to enable the rope to be wound in the wiring groove 18.
As shown in
In the above, the mounting base 2 and the rope winding part 3 may be provided with a mark for alignment, for example, an arrow, and when the arrows on both the mounting base 2 and the rope winding part 3 are aligned, the rope inlet holes 17 on the mounting base 2 will be aligned with the rope threading holes 19 on the rope winding part 3 one by one, thus facilitating the penetration of the rope.
As shown in
In the present embodiment, the rope adjusting device has a simple structure, and fewer components, and is easily disassembled and assembled, and meanwhile, the tightness degree of the rope can be adjusted by one hand, thus the operation is fast and simple.
In other specific embodiments, the rope adjusting device may be provided with a small motor, and the adjusting part 1 may be driven by the motor to rotate. In the above, a driver of the motor may be provided with a wireless communication module, for example, a Bluetooth module and a wifi module, and the user may adjust the tightness degree of shoelace more easily by using a terminal such as cellphone.
In the present embodiment, the rope adjusting device may further include a sewing part 21, wherein the sewing part 21 may be mounted on the mounting base 2, and then the sewing part 21 may be fixed with suture to an article that needs to use the rope adjusting device; and the rope on the rope adjusting device penetrates into a guiding part mounted in a position such as shoe upper. The adjusting part 1 is adjusted so as to control the telescopic length of the rope, and the guiding part is pulled by the rope, so as to achieve the purpose of adjusting the tightness.
In the present embodiment, an article having the rope adjusting device is further provided, including the above rope adjusting device. Specifically, the rope adjusting device may be applied to articles such as shoes, clothes and medical protective gear.
