TECHNICAL FIELD OF THE INVENTION
The application applies for unique system and method for fastening lacing-type footwear.
BACKGROUND OF THE INVENTION
Lacing-type footwear is an important part of our life, but adjusting, tying, and untying laces are time-consuming and frustrating. Plus, bow knots and lace ends are cumbersome, snagging, and hazardous. Accordingly, there are ever-increasing demands for a convenient, safe, and aesthetic system, which could fasten a footwear quickly and easily, could be locked on and released from a footwear quickly and easily, and is affordable, compact, and simple without any cumbersome, hazardous bow knots, lace ends, and components.
PRIOR ART

These aforementioned prior-art patents teach that to fasten a footwear on a foot, a user ties lace ends of a lace together into lengthy, hazardous bows and lace ends, fastens them to a cumbersome, hazardous, expensive device, and exposes them, causing dragging, tripping, snagging, poking, and abrading problems and, thus, inevitable personal injury. They also teach that to release a device from a lace, the lace needs to be untied and/or taken apart. They do not describe nor show a unique system for fastening a footwear on a foot at at least one predetermined tension of a loop. They do not describe nor show a releasably locking device for quickly and easily locking and releasing a loop-section fastener on and from a loop without the needs for taking the loop apart. Therefore, all prior arts heretofore teach away from the present invention.

LOOP-SECTION FASTENER WITH RELEASABLY LOCKING DEVICE
Structure
FIGS. 1 and 2 illustrate the perspective and side views of a loop-section fastener 51. Loop-section fastener 51 comprises two opposite hooks 52a and 52b, a base 53, and a releasably locking device 54. Two opposite hooks 52a and 52b are integrated into each other, and have two opposite hook tips 55a and 55b, respectively. Base 53 is half-pie-shaped, and is integrated into the under-sides of two opposite hooks 52a and 52b. Base 53 has two opposite sides and upper and lower recesses 56a and 56b disposed at predetermined locations thereon, respectively. Releasably locking device 54 comprises a predetermined C-shaped or V-shaped spring, which has two spring ends bent inwards. The C-shaped or V-shaped spring comprises two uneven spring halves 57a and 57b, which are on two intersecting planes, respectively.
FIGS. 3 and 4 illustrate the assemblage of loop-section fastener 51. The spring ends of spring halves 57a and 57b are inserted into recesses 56a and 56b, respectively, to pivotably integrate spring halves 57a and 57b into base 53 and to make spring halves 57a and 57b generally parallel with each other to create a springing force. The springing force pushes releasably locking device 54 back to its original form and, therefore, pushes releasably locking device 54 against hook tip 55a at a contacting area 58, to close the mouth of hook 52a. Releasably locking device 54 can pivot in either one of the opposite directions of an arrow 59 to open or close the mouth of hook 52a. 
Function
Hook tip 55a is predeterminedly bent inward to narrow the mouth of hook 52a, such that hook tip 55a is capable of preventing hook 52a from snagging, poking, etc., and such that hook 52a is capable of securely fastening a loop section thereon when the loop section is hooked thereon, regardless of the tension of the loop section (for example, the loop section can be on a worn or unworn footwear, and the tension of the loop section can be loose or tight or anywhere in between).
Hook tip 55b is predeterminedly bent inward to narrow the mouth of hook 52b, such that hook tip 55b is capable of preventing hook 52b from snagging, poking, etc., and such that hook 52b is capable of securely fastening a loop section thereon when the loop section is hooked thereon, regardless of the tension of the loop section (for example, the loop section can be on a worn or unworn footwear, and the tension of the loop section can be loose or tight or anywhere in between).
Releasably locking device 54 is:

    1) For quickly and easily locking hook 52a of loop-section fastener 51 on a loop section, to quickly and easily fasten loop-section fastener 51 on the loop section, and
    2) For quickly and easily releasing hook 52a of loop-section fastener 51 from a loop section, to quickly and easily unfasten loop-section fastener 51 from the loop section.


Releasably locking device 54 is for releasably locking hook 52a of loop-section fastener 51 on at least one loop section, quickly and easily.
Loop-section fastener 51 is for at least one loop section to be fastened thereon and for at least one loop section to be unfastened therefrom to fasten a footwear on and to unfasten a footwear from a foot, respectively.
Operation
FIGS. 5, 6, and 7 illustrate a method for quickly and easily locking hook 52a of loop-section fastener 51 on a loop section, and another method for quickly and easily releasing hook 52a of loop-section fastener 51 from a loop section. A loop 60 has a loop section 61:

    1) To quickly and easily lock hook 52a of loop-section fastener 51 on loop section 61 (FIGS. 5 and 6):
    
        push loop section 61 against releasably locking device 54 (in the direction of arrow 62a) such that releasably locking device 54 opens, and
        push loop section 61 past releasably locking device 54 (in the direction of arrow 62a) such that releasably locking device 54 closes.
    
    
    2) To quickly and easily release hook 52a of loop-section fastener 51 from loop section 61 (FIGS. 6 and 7):
    
        push loop section 61 against releasably locking device 54 (in the direction of arrow 62b) such that releasably locking device 54 opens, and
        push loop section 61 past releasably locking device 54 (in the direction of arrow 62b) such that releasably locking device 54 closes.
    
    


FIG. 8 illustrates two methods equivalent to the two above-described methods, respectively:

    1) To quickly and easily lock hook 52a of loop-section fastener 51 on loop section 61:
    
        push releasably locking device 54 against loop section 61 (in the direction of arrow 63a) such that releasably locking device 54 opens, and
        push releasably locking device 54 past loop section 61 (in the direction of arrow 63a) such that releasably locking device 54 closes.
    
    
    2) To quickly and easily release hook 52a of loop-section fastener 51 from loop section 61:
    
        push releasably locking device 54 against loop section 61 (in the direction of arrow 63b) such that releasably locking device 54 opens, and
        push releasably locking device 54 past loop section 61 (in the direction of arrow 63b) such that releasably locking device 54 closes.
    
    


FIRST EXAMPLE
Structure
FIGS. 9 and 10 illustrate a unique system for fastening a footwear on a foot. The unique system comprises loop-section fastener 51 (illustrated in FIGS. 1-8), loop 60 (illustrated in FIGS. 5-8), a plurality of opposite loop receivers 64a and 64b of a footwear, and a tongue 65 of the footwear. Loop 60 has a predetermined length to set predetermined loop tension(s). Loop 60 has two opposite loop sections 66a and 66b and two central loop sections 66c and 66d. The footwear has two opposite sides 67a and 67b, on which opposite loop receivers 64a and 64b are disposed, respectively. Tongue 65 has two opposite openings 68a and 68b, a tongue top 69, and outer and inner surfaces. Each of two opposite openings 68a and 68b extends from the outer surface to the inner surface of tongue 65.
The footwear is laced with loop 60, such that each of loop sections 66a and 66b extends between two of loop-receivers 64a and 64b on the same side, and such that central loop section 66c extends between two opposite openings 68a and 68b of tongue 65 and hides inside tongue 65. Releasably locking device 54 of loop-section fastener 51 is pushed against and past loop section 66a to releasably lock hook 52a of loop-section fastener 51 on loop section 66a, quickly and easily, to fasten loop-section fastener 51 on loop section 66a (see the example in FIGS. 5, 6, 7, and 8 above).
Material
The material(s), used to make each component of the unique system, can partially or entirely be rigid, non-rigid, flexible, non-flexible, pliable, non-pliable, elastic, non-elastic, resilient, non-resilient, etc. . . . , or a combination of at least two of the above. For example, the material, used to make each component of the unique system, can partially or entirely be leather, vinyl, nylon, cotton, wool, fabric, foam, plastic, plastic composite, plasticized material, Zytel nylon, neon material, glow-in-the-dark material, fluorescent material, glittering material, light-reflecting material, rubber, steel, aluminum, alloy, titanium, bronze, iron, zinc, tin, copper, metal, carbon fiber, the like, the equivalent, etc. . . . , or a combination of at least two of the above.
Operation
FIGS. 9, 10, and 11 illustrate two unique methods for fastening and unfastening the footwear on and from a foot, respectively. After inserting a foot into the footwear:

    1) To fasten the footwear on the foot, hook loop section 66b on hook 52b of loop-section fastener 51, to fasten loop section 66b on loop-section fastener 51.
    2) To unfasten the footwear from the foot, unhook loop section 66b from hook 52b of loop-section fastener 51, to unfasten loop section 66b from loop-section fastener 51.
    
        (For example, to unhook loop section 66b from hook 52b, a person can lift hook 52b with one finger until loop section 66b slides off hook 52b).

Advantages

    
    


Referring to FIG. 11, when the unique system fastens the footwear on the foot, it fastens the two top opposite ones of opposite loop receivers 64a and 64b right on top of two opposite openings 68a and 68b of tongue 65, respectively (with central loop section 66c extending inside tongue 65 between two opposite openings 68a and 68b of tongue 65). As a result, at the same time, the unique system:

    1) Automatically lifts tongue 65 at tongue top 69 to straighten the whole tongue 65, resulting from loop 60 threaded through the two top opposite ones of opposite loop receivers 64a and 64b and through two opposite openings 68a and 68b at tongue top 69, which eliminates the problem of tongue top 69 sagging, at every step;
    2) Automatically centers tongue 65 between two opposite sides 67a and 67b, resulting from loop 60 threaded through the two top opposite ones of opposite loop receivers 64a and 64b and through two opposite openings 68a and 68b at tongue top 69, which eliminates the problem of the foot becoming unprotected and exposed, at every step;
    3) Automatically locks tongue 65 between two opposite sides 67a and 67b, resulting from loop 60 threaded through the two top opposite ones of opposite loop receivers 64a and 64b and through two opposite openings 68a and 68b at tongue top 69, which eliminates the problem of tongue 65 sliding sideways, at every step;
    4) Automatically interlocks tongue 65 and two opposite sides 67a and 67b. As a result, the more two opposite sides 67a and 67b are pulled apart, the more securely they are locked together, which eliminates the problem of the footwear warping, at every step;
    5) Automatically interlocks tongue 65 and two opposite loop sections 66a and 66b. As a result, the more two opposite loop sections 66a and 66b are pulled apart, the more securely they are locked together, which eliminates the problem of using hazardous messy bows and lace ends, the problem of tying and untying every time the footwear is worn, and the problem of re-tying and re-untying every time the bows become loose; and
    6) Automatically fastens the footwear at predetermined loop tension(s) of loop 60, which eliminates the problems of adjusting and re-adjusting the tension of a conventional lace every time the footwear is fastened on the foot, and eliminates the problems of guessing and searching for ‘the’ favorite tension of a conventional lace every time the footwear is fastened on the foot.


FIG. 12 illustrates the unique capabilities of releasably locking device 54 (see the example in FIG. 4 above) of loop-section fastener 51, which allows loop-section fastener 51:

    1) To be locked on the loop section of a loop, quickly and easily, without the needs for taking the loop apart;
    2) To be released from the loop section of a loop, quickly and easily, without the needs for taking the loop apart;
    3) To be worn upside down or right side up, quickly and easily, without the needs for taking the loop apart;
    4) To be removed to add decoration or device to it, quickly and easily, without the needs for taking the loop apart;
    5) To be interchanged with another loop-section fastener, quickly and easily, without the needs for taking the loop apart;
    6) To be replaced with another loop-section fastener, quickly and easily, without the needs for taking the loop apart, for example, of:
    
        a) Different design for different mood, fashion, etc.,
        b) Different length for different loop tension, etc.,
        c) Different shape for additional capability, etc.,
        d) Different material for different capability, etc.
    
    


For example, loop-section fastener 51 can quickly and easily be replaced with a loop-section fastener 70, which is similar to and equivalent to loop-section fastener 51. Loop-section fastener 70 has a relief of a heart integrated thereinto for decoration and for making the surface of loop-section fastener 70 non-slippery. To quickly and easily replace loop-section fastener 51 with loop-section fastener 70:

    1) Push loop section 66a against and past releasably locking device 54 of loop-section fastener 51 (see the example in FIGS. 6 and 7 above) to quickly and easily release loop section 66a from loop-section fastener 51, and
    2) Push loop section 66a against and past a releasably locking device of loop-section fastener 70 (see the example in FIGS. 5 and 6 above) to quickly and easily lock loop section 66a on loop-section fastener 70.
