Specifically, please continue refer to the
When said control member 11 is pressed against said disengaging portion 212, the control claw 21 is driven to rotate for a certain angle to make said clamping teeth separated from said control portion 31 (as shown in
Taking this embodiment as an example, the user rotates the top cover 10 clockwise so that the control member 11 is against the disengagement portion 212, pushing the control member 21 to rotate to disengage the clamping teeth from the control portion 31, at which time the rope outside the escapement rotary control clutch is pulled to release the rope.
Specifically, the number of said control members 11 is the same as that of said control claws 21 to facilitate each control claw 21 is subject to control of control member 11 and make the structure pulling the escapement rotary control clutch more stable.
Specifically, said first engagement structure 23 is pawl, and said second engagement structure 421 comprises a plurality of teeth, a plurality of said teeth being disposed circumferentially along the inner wall of said base 40 to form a tooth ring, the pawl moves unidirectionally within the tooth ring. It is worth mentioning that the second engagement structure 421 is a wedge-shaped structure, and when the first engagement structure 23 and the second engagement cooperate with each other, the control disk 22 can only rotate unidirectionally, but cannot rotate in the opposite direction.
Specifically, limiting members 24 are provided on the periphery of said control disk 22, said limiting members 24 being provided adjacent to said control claws 21 to limit rotation angle of the control claws 21 and prevent control claws 21 from rotate excessively.
More specifically, said limiting members 24 are provided in two, and said limiting members 24 are provided opposite each other; there are two first engagement structures 23 and are arranged opposite to each other. The limiting member 24 and the first engagement structure 23 are both provided on the periphery of the control disk 22, but not on the same side.
Specifically, the middle of said top cover 10 is further provided with a buckle 12, the middle of said spool 30 is provided with a buckle channel 33 for said buckle 12 to pass through, and said buckle channel 33 is internally provided with a buckle platform 331 for said buckle 12 to clamp to. When assembling the escapement rotary control clutch, it is sufficient to clamp the buckle 12 of the top cover 10 onto the buckle platform 331 of the spool 30, which makes the assembly quick and easy, saving time and effort.
Specifically, said base 40 comprises base body 41 and barrel 42 mounted on said base body 41, said barrel 42 being provided with the first rope hole 422 for the rope to pass through. In practice, the base body 41 is fixed to a wearable object, such as shoes, pants, etc. to enable the escapement rotary control clutch to assist in tightening or releasing the rope.
The bottom of said barrel 42 is provided with clamping member 423, and said base body 41 is provided with bayonet 411 for said clamping member 423 to clamp into, which is easy and quick to assemble.
The winding portion 32 of said spool 30 is provided with a second rope hole 34 for the rope to pass through. The interior of the spool 30 is a hollow structure, and in actual use, the two free ends of the rope body may be threaded into the hollow structure of the spool 30 from the second rope hole 34, and the free ends of the rope are knotted and stowed in the hollow structure.
It is to be understood that the control disk 22 in the escapement rotary control clutch is provided with the first engagement structure 23, and the second engagement structure 421 is provided in the upper portion of the base 40, wherein the first engagement structure 23 is unidirectionally engaged with the second engagement structure 421 to enable the control component 20 to be rotated only in a unidirectional direction along the base 40, and not in a reverse direction. The present application achieves the purpose of tightening or releasing the rope by controlling whether or not the spool 30 is linked with the control component 20. When the spool 30 is linked with the control component 20, then the spool 30 is subject to the unidirectional engagement of the first engagement structure 23 and the second engagement structure 421; and when the spool 30 is not linked with the control component 20, then the spool 30 is in a free state. When the user rotates the top cover 10 so that the control member 11 rests against the engagement portion 211 of the control claw 21, thereby actuating the clamping teeth on the disengagement portion 212 of the control claw 21 to stuck against the control portion 31 on spool 30, the collection of the rope is accomplished by continually rotating the top cover. When the rope is collected to the proper tightness, the user releases the top cover 10 and the rope still maintains the current tightness. The direction in which the control component 20 can rotate only unidirectionally along the base 40 should be consistent with the rotating direction of the top cover 10. When the user reversely rotate the top cover 10 so that the control member 11 rests against the disengaging portion 212 of the control claw 21, the control member 21 is pushed to rotate to disengage the clamping teeth from the control portion 31, and at this time the rope outside the escapement rotary control clutch is pulled to release the rope.
The advantageous effects of the escapement rotary control clutch of the embodiment lies in that: by positively or negatively rotating the top cover 10 to switch whether or not the control member 11 in the control component 20 is linked to the spool 30, thereby switching the using state of the escapement rotary control clutch, quickly realizing tightening or loosening of a rope.
In the above embodiment, the escapement rotary control clutch is used on wearable objects that require lacing, such as footwear, medical protective gear and the like. Preferably, the escapement release rotary control clutch is used on shoes to adjust the tightness of the shoelaces.
In this embodiment, the counterclockwise direction is assumed to be the direction of tightening the rope, but is not limited thereto. In other embodiments, due to the different habits of people using the right and left hands, it may be set to the clockwise direction as the tightening rope direction, and it is only necessary to change the direction of the unidirectional engagement of the first engagement structure 23 and the second engagement structure 421 as well as to correspondingly adjust the direction of the gears of the control claw 21 and the control portion 31, and the other principles are the same as in the present embodiment, and will not be further discussed herein.
The above description of the invention and the embodiments thereof is not restricted, and the accompanying drawings are only one of the embodiments of the invention, and the actual structure is not limited thereto. In conclusion, the similar structures and embodiments with the technical scheme of the invention, which are designed by the general skilled person in the art inspired by the invention, without creativity and without departing from the spirit of the invention, should be included in the protection scope of the invention.
