A knot-free device

Abstract

This invention discloses a knot-free device, belonging to the field of rope knotting technology. It includes: a connecting plate, a mounting base plate, and a limiting plate. The mounting base plate is hinged to both ends of the connecting plate. The first end of the limiting plate is hinged to the first end of the mounting base plate. A mounting clip is provided at the tail end of the mounting base plate. A support plate is provided at the tail end of the limiting plate. The mounting clip is engaged with the tail end of the limiting plate, and the support plate supports the engaged limiting plate. The limiting plate contains a limiting rod and a guide rod. The limiting rod has an edge, which limits the displacement of the rope. The guide rod causes the rope passing over the limiting rod to form an acute angle after being engaged with the limiting plate, thus limiting the movement of the rope. This invention eliminates the need for rope knots. Pulling the rope taut to both sides utilizes the edge of the limiting rod and the engaging of the limiting plate with the mounting base plate to create an acute angle, thus limiting the rope's displacement. Pulling the rope vertically upward releases the edge's restriction on the rope, allowing it to be easily released.

Description

Technical Field

[0001] This invention belongs to the field of rope and ribbon knotting technology, and particularly relates to a knotless device. Background Technology

[0002] In daily life, knots are often needed in various situations. The most typical example is tying a knot after tightening shoelaces. Other scenarios include using a drawstring around the opening of a bag to tighten it; and knotting the opening of clothing, such as the Chinese-style top. When tying knots on shoes, some people tie them loosely, allowing long laces to easily dangle, increasing the risk of accidents while walking or exercising. In other cases, loosening the shoelaces can result in a knot that is difficult to untie. Similarly, when tying a knot at the opening of a bag, a loose knot can cause the opening to come undone or become a knot that is difficult to untie. And the small holes in the Chinese-style buttons on clothing can make them difficult to fasten.

[0003] While automatic knot-tying devices exist in the existing technology, their structures lack versatility and cannot be widely used on clothing, bags, and shoes. Furthermore, these devices often use a ratchet-like structure to restrain the tightened shoelaces, thus achieving the function of automatic tying. However, the ropes are often woven, and over time, they can be damaged by ratchet-like components.

[0004] Chinese patent (CN102551276A) discloses a shoelace lacing device that relies on the mesh or ribs on the surface of the roller to restrict the movement of the shoelaces. The mesh or ribs rub against the shoelaces for a long time, causing the shoelace surface to become fuzzy and damaging the shoelaces. Summary of the Invention

[0005] In view of this, the present invention provides a knot-free device to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A knot-free device includes: a connecting plate, a mounting base plate, and a limiting plate. A pair of mounting base plates are hinged to both ends of the connecting plate. The first end of the limiting plate is hinged to the first end of the mounting base plate. A mounting clip is provided at the tail end of the mounting base plate. A support plate is provided at the tail end of the limiting plate. The mounting clip is engaged with the tail end of the limiting plate. The support plate supports the limiting plate after engagement. A limiting rod and a guide rod are provided within the limiting plate. The limiting rod has an edge for limiting the displacement of a rope. The guide rod causes a rope that passes over the limiting rod to form an acute angle after engagement with the limiting plate, thus limiting the movement of the rope.

[0008] Furthermore, a pair of support plates are located on both sides of the mounting clip.

[0009] Furthermore, it also includes a snap-fit ​​device, which includes a snap-fit ​​plate and a spring. The tail end of the limiting plate is provided with a snap-fit ​​sliding part, and the snap-fit ​​sliding part is provided with a pair of sliding grooves. The snap-fit ​​plate is slidably installed in the sliding grooves, and the two ends of the spring are respectively fixedly installed on the side walls of the snap-fit ​​plate and the sliding grooves.

[0010] Furthermore, the snap-fit ​​device also includes an elastic band, the two ends of which are fixedly installed on the opposite sidewalls of the pair of snap-fit ​​plates. A rope passes through the snap-fit ​​sliding part and the mounting base plate, goes around the limiting rod and the guide rod, and then passes out between the elastic band and the snap-fit ​​sliding part.

[0011] Furthermore, the connecting plate is provided with a mounting bracket.

[0012] The beneficial effects of this invention are as follows:

[0013] This invention allows the limiting plate to be engaged with the mounting base plate at its tail end. A limiting rod and guide rod are used to form an acute angle around the rope as it wraps around the limiting rod, thus limiting the rope's displacement. To release the rope, the tail end of the limiting plate is first disengaged from the mounting clip on the mounting base plate, allowing the limiting plate to rotate around the hinge axis. This causes the rope to form a right or obtuse angle around the limiting rod, at which point the edge does not restrict the rope, allowing for easy release. Support plates on both sides of the mounting clip not only provide limiting support after the tail end of the limiting plate is engaged, but also protect the mounting clip from damage during normal movement. The spring moves outwards within the groove. Pushing the snap-fit ​​plate engages the mounting clip, securing the tail end of the limiting plate to the mounting base. If the structure securing the mounting clip is a fixed structure on the limiting plate, the mounting clip will fail after repeated use. The design of the spring and snap-fit ​​plate increases the service life of the mounting clip. To release the rope, simply pull the rope upwards. Pulling the elastic band upwards will cause the snap-fit ​​plate to compress the springs, releasing the mounting clip from the limiting plate. Then, by rotating the limiting plate around the hinge axis, the rope can be easily released. The mounting bracket on the connecting plate can accommodate various graphic symbols or rope knotting styles, enhancing aesthetics. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] See attached document Figure 1-7As shown, the present invention provides a knot-free device, comprising: a connecting plate 10, a mounting base plate 20, and a limiting plate 30. A pair of mounting base plates 20 are hinged to both ends of the connecting plate 10, and the first end of the limiting plate 30 is hinged to the first end of the mounting base plate 20. The two mounting base plates 20 and the connecting plate 10 are hinged to utilize the shape of the instep. A mounting clip 21 is provided at the tail end of the mounting base plate 20, and a support plate 31 is provided at the tail end of the limiting plate 30. The mounting clip 21 is snapped into the tail end of the limiting plate 30, and the support plate 31 is used to support the limiting plate 30 after it is snapped in place. A limiting rod 32 and a guide rod 33 are provided in the limiting plate 30. An edge 321 is provided on the limiting rod 32, which is used to limit the displacement of the rope 50. The guide rod 33 is used to make the rope 50 that passes around the limiting rod 32 form an acute angle after it is snapped in place by the limiting plate 30, thereby limiting the movement of the rope 50.

[0026] In a preferred embodiment, a pair of support plates 31 are located on both sides of the mounting clip 21. The support plates 31 on both sides of the mounting clip 21 can not only provide limiting support after the tail end of the limiting plate 30 is engaged, but also protect the mounting clip 21 from damage during daily movement.

[0027] In a preferred embodiment, the knot-free device further includes a snap-fit ​​device 40, which includes a snap-fit ​​plate 41 and a spring 42. The tail end of the limiting plate 30 is provided with a snap-fit ​​sliding part 34, and a pair of sliding grooves 341 are provided on the snap-fit ​​sliding part 34. The snap-fit ​​plate 41 is slidably installed in the sliding grooves 341. The two ends of the spring 42 are respectively fixedly installed on the side walls of the snap-fit ​​plate 41 and the sliding grooves 341. The spring 42 pushes the snap-fit ​​plate 41 outward in the sliding grooves 341 to snap the mounting clip 21 and fix the tail end of the limiting plate 30 to the mounting base plate 20. If the structure that snaps the mounting clip 21 is a fixed structure on the limiting plate 30, the mounting clip 21 will fail after multiple uses. The design of the spring 42 and the snap-fit ​​plate 41 can increase the service life of the mounting clip 21.

[0028] In a preferred embodiment, the locking device 40 further includes an elastic band 43, with both ends of the elastic band 43 fixedly mounted on the opposite sidewalls of a pair of locking plates 41. A rope 50 passes between the locking sliding part 34 and the mounting base plate 20, wraps around the limiting rod 32 and the guide rod 33, and then exits between the elastic band 43 and the locking sliding part 34. To release the rope 50, simply pull the rope 50 upwards. By pulling the elastic band 43 upwards, the locking plates 41 compress the springs 42 and move towards each other, thereby releasing the mounting clip 21 from the limiting plate 30.

[0029] In a preferred embodiment, the connecting plate 10 is provided with a mounting bracket 11, which can be used to install various graphic symbols or various knotted styles of ropes 50 to enhance aesthetics.

[0030] Example

[0031] When fastening the rope 50, the rope 50 has already passed between the locking sliding part 34 and the mounting base plate 20, passed around the limiting rod 32, and then passed out from the bottom end of the guide rod 33, and then from between the elastic band 43 and the locking sliding part 34. When tightening the rope 50, pull the rope 50 on both sides with both hands and press it down, so that the rope 50 presses down on the locking sliding part 34, causing the limiting plate 30 to rotate around the hinge axis, so that the mounting clip 21 is locked on the locking plate 41, and the portion of the rope 50 that passes around the limiting rod 32 is secured by the limiting rod 32 and the guide rod 33. An acute angle is formed, and the displacement of the rope 50 is restricted by the edge 321. At this time, the rope 50 is tightened and will not loosen. When the rope 50 is loosened, simply pull the rope 50 upward. By pulling the elastic band 43 upward, the clamping plate 41 will compress the spring 42 and move in opposite directions. This will release the clamping clip 21 from the clamping plate 30, allowing the clamping plate 30 to rotate around the hinge axis. This will cause the part of the rope 50 that passes around the clamping rod 32 to form a right angle or an obtuse angle. At this time, the edge 321 will not restrict the rope 50, and the rope 50 can be easily loosened.
