[0024] The following examples are merely used to illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention, so it is clearly stated in advance.
[0025] Please refer to Figures 1 to 8 , which shows an embodiment of the present invention. The adjustable shoe 1 of the present invention includes a sole 10 , a shoe body 20 , a heel adjuster 30 and an adjustment assembly 40 .
[0026] The sole 10 includes a guide groove 11, and the sole 10 is defined by a longitudinal direction L. The shoe body 20 is connected to the sole 10. The heel adjuster 30 is arranged in the shoe body 20, and the heel adjuster 30 includes a receiving shell 31 for receiving a heel of a foot and at least one guide pin 32 extending from the receiving shell 31. The at least one guide pin 32 is inserted into the guide groove 11, and the receiving shell 31 is located above the sole 10. The adjustment component 40 is rotatably arranged on the sole 10, and the adjustment component 40 includes a screw segment 41 screwed to the at least one guide pin 32. Rotating the adjustment component 40 can drive the at least one guide pin 32 to move in the guide groove 11 along the longitudinal direction L, so that the relative position of the receiving shell 31 relative to the heel 21 of the shoe body 20 in the longitudinal direction L changes ( Figure 2 ). Thus, the adjustable shoe 1 can be adjusted in size, and its sole 10 and appearance are integral without being segmented, and have good covering, comfort and protection.
[0027] The adjustable shoe 1 can be any footwear product with a heel. For example, if the sole 10 is additionally equipped with a wheel frame equipped with multiple pulleys, the adjustable shoe can be a skate. If the sole 10 only includes a midsole and an outsole, the adjustable shoe can be an athletic shoe, a casual shoe, a boot, or other footwear. The sole 10 can be a single, integrally molded component or a multi-layered structure. The shoe body 20 can be a flexible component (e.g., a lining kit). In the field of sporting goods, the shoe body 20 is a flexible component. A relatively rigid shoe shell connected to the sole 10 can be provided on the outside of the shoe body 20 to provide good structural strength and protection.
[0028] The sole 10 further includes a first partition wall 12 and a second partition wall 13 spaced apart in the longitudinal direction L. The first partition wall 12 and the second partition wall 13 divide the guide groove 11 into a first groove area 111, a second groove area 112, and a third groove area 113 located between the first groove area 111 and the second groove area 112. The heel adjuster 30 includes a first guide pin 33 inserted into the first groove area 111 and a second guide pin 34 inserted into the second groove area 112. The multiple guide pins can provide a stable connection and guiding effect. The adjustment assembly 40 further includes a drive rod 42 rotatably inserted into the sole 10. The drive rod 42 includes the threaded section 41 and a radial annular protrusion 43. The radial annular protrusion 43 is rotatably accommodated in the third groove area 113 and is limited between the first partition wall 12 and the second partition wall 13, making it easy to assemble and providing stable positioning. The second guide pin 34 includes a thread 341 that is threadably engaged with the threaded segment 41 of the adjustment assembly 40. In this embodiment, the second guide pin 34 includes a half-threaded hole, which facilitates assembly and allows for quick engagement with the threaded segment 41. Thus, the heel adjuster 30 can be moved by rotating the drive rod 42 to thread the second guide pin 34, thereby adjusting the size of the adjustable shoe 1.
[0029] Specifically, the width of the second groove section 112 is greater than the width of the first groove section 111, and the width of the second guide pin 34 is greater than the width of the first guide pin 33, thereby providing good structural strength and stable guidance. The housing 31 extends forward to form an elongated portion 35, and the first guide pin 33 is disposed in the elongated portion 35. The elongated portion 35 covers at least a portion of the first groove section 111. This reduces the hollowing area of the first groove section 111, and the sole 10 can maintain greater structural strength.
[0030] The sole 10 further includes a plurality of guide posts 14 located on opposite sides of the guide slot 11. The housing 31 further includes a plurality of guide slots 36. The guide posts 14 are respectively inserted into the guide slots 36. The adjustable shoe 1 further includes a stopper 50 and a plurality of fasteners 60. The fasteners 60 pass through the stopper 50 and are respectively fixed to the guide posts 14. The housing 31 is movably sandwiched between the stopper 50 and the sole 10. This stabilizes and strengthens the structure of the heel adjuster 30.
[0031] Preferably, at least one supporting leg 37 (preferably multiple) is convexly provided on the bottom surface of the receiving shell 31, and a gap G ( Figure 7 ), which can reduce friction and facilitate adjustment of the heel adjuster 30. When the load of the housing 31 causes the driving rod 42 to be stressed and deformed radially, the at least one supporting leg 37 is supported on the top surface of the sole 10 ( Figure 8 ), which can avoid damaging the driving rod 42 and preventing the receiving shell 31 from moving arbitrarily relative to the driving rod 42 to change the size of the adjustable shoe 1.
[0032] In this embodiment, the housing 31 includes a housing body 38 and a tongue 39. The housing body 38 includes the at least one guide pin 32. The tongue 39 is pivotally connected to the upper end of the housing body 38 and can swing to abut against the inner surface of the shoe body 20. Preferably, the housing 31 further includes an elastic member 70. The elastic member 70 elastically abuts between the housing body 38 and the tongue 39 and pushes the tongue 39 toward the inner surface of the shoe body 20. As the heel adjuster 30 moves away from the inner surface of the shoe body 20, the tongue 39 swings toward the inner surface of the shoe body 20, eliminating or reducing the gap between the heel adjuster 30 and the inner surface of the shoe body 20. Furthermore, the tongue 39 can function like a shoe horn, facilitating wearing.
[0033] The above is a preferred embodiment of the present invention and the technical principles used therein. For those skilled in the art, any obvious changes such as equivalent transformations, simple replacements, etc. based on the technical solution of the present invention, without departing from the spirit and scope of the present invention, shall fall within the scope of protection of the present invention.
