Description

Technical Field

[0001] This invention relates to the field of footwear technology, and more specifically to shoes with replaceable uppers. Background Technology

[0002] Currently, shoe soles and uppers are fixed, one-piece designs that cannot be easily separated. When different colors or decorations are needed, various complete pairs of shoes must be purchased. Therefore, the integrated sole and upper structure is unsuitable for diverse needs. To address this issue, patent CN113940480B provides a sports shoe with a replaceable upper. This patented invention uses several fixing devices on the sole to secure the upper. However, when the upper needs to be replaced, each fixing device must be operated individually to release the upper or re-fix the new upper. This makes changing the upper relatively cumbersome and inconvenient, thus requiring further improvement. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a shoe with a replaceable upper, in which multiple locking mechanisms can be simultaneously controlled to lock or release by operating only the tightening and resetting mechanism, so as to release the fixation of the upper or re-fix the newly replaced upper, making the replacement of the upper simpler and more convenient.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a shoe with replaceable upper, including a sole and an upper, wherein a snap-fit ​​mechanism is provided between the upper and the sole, and the upper is detachably connected to the upper end of the sole through multiple snap-fit ​​mechanisms. The multiple snap-fit ​​mechanisms are arranged at intervals along the circumference of the sole and the upper, and a tightening and resetting mechanism is provided on the sole for simultaneously controlling the multiple snap-fit ​​mechanisms to snap or separate.

[0005] Furthermore, the locking mechanism includes a sliding sleeve, a locking rod, and an insert block. The upper surface of the sole is provided with a fixing groove adapted to the sliding sleeve and a slot adapted to the insert block. The sliding sleeve is fixedly installed in the fixing groove. The sliding sleeve is provided with a sliding cavity that extends through both ends of the sliding sleeve. The locking rod is slidably installed in the sliding cavity. The insert block is fixedly installed at the bottom of the upper. The insert block is provided with a locking hole that extends through both ends of the insert block. The insert block can be detachably inserted into the slot and the locking hole corresponds to the locking rod. The tightening and resetting mechanism is used to drive the locking rod to slide. One end of the locking rod can pass through the sliding cavity and can be detachably locked into the locking hole.

[0006] Furthermore, the locking hole is conical, one end of the locking rod is adapted to the locking hole, and an elastic layer is fixedly covered on the outer conical surface of one end of the locking rod.

[0007] Furthermore, the tightening and resetting mechanism includes a tightening pull assembly, a reset spring, and two pull ropes. The tightening pull assembly is located at the rear end of the sole. The left and right sides of the upper surface of the sole are provided with rope-passing channels that communicate with the corresponding fixing grooves and slots. The two pull ropes are respectively passed through the two rope-passing channels and fixedly connected to multiple locking rods on the corresponding sides. The central axis of the locking rods coincides with the central axis of the pull ropes. One end of the pull ropes passes through the sole and is connected to the tightening pull assembly. The tightening pull assembly is used to pull the pull ropes and drive the locking rods into the locking holes. The bottom end of the insert block is provided with a slot that communicates with the locking holes and allows the pull ropes to pass through. The reset spring is sleeved on the locking rods and located in the sliding cavity. The reset spring is used to always apply an elastic force away from the locking holes to the locking rods. Both ends of the sliding sleeve are also fixedly installed with annular limiting plates for limiting the locking rods.

[0008] Furthermore, a guide tube is fixedly installed inside the rope-threading channel, and the pull rope is threaded through the guide tube, which has a U-shaped longitudinal section.

[0009] Furthermore, the tightening and pulling assembly includes a base cylinder and a cap. A positioning toothed ring is fixedly provided on the upper part of the inner circumference of the base cylinder, and two symmetrical rope-passing holes are provided on the lower part of the base cylinder. A fixed shaft is fixedly provided in the center of the base cylinder. The cap is located on the upper end of the base cylinder and is rotatably connected to the fixed shaft. A rope-winding block is fixedly provided at the bottom end of the cap. One end of the pull rope passes through the corresponding rope-passing hole and is fixedly connected to the rope-winding block. A pressing groove penetrating its outer circumference is provided on the upper surface of the cap, and a positioning groove penetrating its outer circumference is provided on the bottom surface of the cap. The cap contains a groove for connecting the pressing groove and the positioning groove. The connector has a connecting port, a movable pressing block inside the pressing groove, one end of which can extend out of the pressing groove. A movable positioning block is provided in the positioning groove, the tip of which can extend out of the positioning groove and be detachably engaged with the positioning tooth ring. The other end of the positioning block passes through the connecting port and is fixedly connected to the pressing block. A positioning spring is provided in the pressing groove. The positioning spring is used to always apply an elastic force towards the positioning tooth ring to the pressing block and to engage the tip of the positioning block with the positioning tooth ring. A sealing plate is fixedly installed at the upper end of the cap at the opening of the pressing groove.

[0010] Furthermore, an ankle support piece is fixedly provided on the upper rear side of the sole. The cross-section of the ankle support piece is U-shaped, and both the left and right sides of the ankle support piece are detachably connected to the upper through connectors.

[0011] Furthermore, V-shaped notches are provided on both the left and right surfaces of the ankle wrap, and elastic sheets are fixedly connected to the V-shaped notches on the ankle wrap.

[0012] Furthermore, the bottom of the shoe upper is closed and forms a closed bottom surface, and there is an opening at the upper rear of the shoe upper. There is a detachable insole inside the shoe upper.

[0013] Furthermore, the bottom of the closed bottom surface is fixed with multiple inserts, and the upper surface of the sole is provided with multiple grooves that are adapted to and correspond one-to-one with the inserts. The inserts can be separably embedded in the grooves and can be magnetically fixed to the sole.

[0014] As can be seen from the above description, the replaceable upper shoe provided by the present invention has the following beneficial effects: the multiple snap-fit ​​mechanisms facilitate fixing the upper to the sole, and the tightening and resetting mechanism can simultaneously control the multiple snap-fit ​​mechanisms to snap or separate. In this way, when the upper needs to be replaced, only the tightening and resetting mechanism needs to be operated to release the fixation of the upper or to re-fix the newly replaced upper. This makes the replacement of the upper simpler and more convenient. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below through specific embodiments.

[0025] like Figures 1 to 8 As shown, the replaceable upper shoe of the present invention includes a sole 1 and an upper 2. A snap-fit ​​mechanism 3 is provided between the upper 2 and the sole 1. The upper 2 is detachably connected to the upper end of the sole 1 through a plurality of snap-fit ​​mechanisms 3. The plurality of snap-fit ​​mechanisms 3 are arranged at intervals along the circumference of the sole 1 and the upper 2. The sole 1 is provided with a tightening and resetting mechanism 4 for simultaneously controlling the snap-fit ​​or separation of the plurality of snap-fit ​​mechanisms 3.

[0026] The multiple locking mechanisms 3 facilitate the fixing of the upper 2 to the sole 1. Simultaneously, the tightening and resetting mechanism 4 controls the locking and disengaging of the multiple locking mechanisms 3. Therefore, when the upper 2 needs to be replaced, simply operating the tightening and resetting mechanism 4 releases the upper 2 from its fixation or re-fixes the newly replaced upper 2, making the replacement of the upper 2 simpler and more convenient.

[0027] Accordingly, the shoe can be classified as a casual shoe.

[0028] Specifically, the locking mechanism 3 includes a sliding sleeve 31, a locking rod 32, and an insert block 33. The upper surface of the sole 1 is provided with a fixing groove adapted to the sliding sleeve 31 and a slot 11 adapted to the insert block 33. The sliding sleeve 31 is fixedly disposed in the fixing groove, and the sliding sleeve 31 is provided with a sliding cavity penetrating both ends therethrough. The locking rod 32 is slidably disposed in the sliding cavity. The insert block 33 is fixedly disposed at the bottom end of the upper 2, and the insert block 33 is provided with locking holes 331 penetrating both ends therethrough. The insert block 33 is detachably inserted into the slot 11, and the locking holes 331 correspond to the locking rod 32. The tightening and resetting mechanism 4 is used to drive the locking rod. The lever 32 slides, and one end of the lever 32 can pass through the sliding cavity and be detachably locked in the locking hole 331. With this structure, when one end of the lever 32 passes through the sliding cavity and is locked in the locking hole 331 of the insert block 33 under the drive of the tightening and resetting mechanism 4, the locking mechanism 3 can be locked, thereby fixing the shoe upper 2 to the shoe. When one end of the lever 32 retracts into the sliding cavity and disengages from the locking hole 331 of the insert block 33 under the drive of the tightening and resetting mechanism 4, the locking mechanism 3 can be disengaged. At this time, the shoe upper 2 can be removed from the shoe and the shoe upper 2 can be replaced.

[0029] Preferably, the locking hole 331 is conical, one end of the locking rod 32 is adapted to the locking hole 331, and an elastic layer is fixedly covered on the outer conical surface of one end of the locking rod 32. Correspondingly, the elastic layer is made of silicone or rubber. This helps to improve the stability of the locking rod 32 in the locking hole 331, thereby further improving the stability of the connection between the shoe upper 2 and the shoe sole 1.

[0030] Specifically, the tightening and resetting mechanism 4 includes a tightening pull assembly 41, a resetting spring 42, and two pull ropes 43. The tightening pull assembly 41 is located at the rear end of the sole 1. The upper surface of the sole 1 has rope-threading channels on both the left and right sides that communicate with the corresponding fixing groove and slot 11. The two pull ropes 43 are respectively threaded through the two rope-threading channels and fixedly connected to multiple locking rods 32 on the corresponding sides. The central axis of the locking rods 32 coincides with the central axis of the pull ropes 43. One end of each pull rope 43 extends out of the sole 1 and connects to the tightening pull assembly 41. The tightening pull assembly 41 is used to pull the pull ropes 43 and cause the locking rods 32 to engage with the locking holes. Inside 331, the bottom end of the insert 33 is provided with a slot 332 that communicates with the locking hole 331 and allows the pull rope 43 to pass through. Preferably, the slot 332 is a figure-eight shape that is wider at the bottom and narrower at the top. The return spring 42 is sleeved on the locking rod 32 and located in the sliding cavity. The return spring 42 is used to always apply an elastic force to the locking rod 32 away from the locking hole 331. Both ends of the sliding sleeve 31 are also fixedly installed with annular limiting plates 34 for limiting the locking rod 32. Specifically, one end of the return spring 42 abuts against the annular protrusion on the locking rod 32, and the other end of the return spring 42 abuts against one of the annular limiting plates. 34 abuts against each other. Furthermore, the tightening and pulling assembly 41 includes a base cylinder 411 and a cap 412. A positioning gear ring 4111 is fixedly provided on the upper part of the inner circumference of the base cylinder 411. Two symmetrical rope-passing holes 4112 are provided on the lower part of the base cylinder 411. A fixed shaft 4113 is fixedly provided at the center of the inner part of the base cylinder 411. The cap 412 is located at the upper end of the base cylinder 411 and is rotatably connected to the fixed shaft 4113. A rope-winding block 4121 is fixedly provided at the bottom end of the cap 412. One end of the pull rope 43 passes through the corresponding rope-passing hole 4112 and is fixedly connected to the rope-winding block 4121. A pressing groove 4122 penetrating its outer circumference is provided on the upper surface of the cap 412. 2. A positioning groove 4123 penetrating its outer circumference is provided on the bottom end face. The screw cap 412 has a communication port 4124 for connecting the pressing groove 4122 and the positioning groove 4123. A movable pressing block 413 is provided in the pressing groove 4122. One end of the pressing block 413 can protrude from the pressing groove 4122. A movable positioning block 414 is provided in the positioning groove 4123. The tip of the positioning block 414 can protrude from the positioning groove 4123 and be detachably engaged with the positioning toothed ring 4111. The other end of the positioning block 414 passes through the communication port 4124 and is fixedly connected to the pressing block 413. A positioning spring 415 is provided in the pressing groove 4122.The positioning spring 415 is used to consistently apply an elastic force toward the positioning toothed ring 4111 to the pressing block 413, and to engage the tip of the positioning block 414 with the positioning toothed ring 4111. A sealing plate 416 is fixedly installed at the upper end of the cap 412 at the opening of the pressing groove 4122. Correspondingly, one end of the positioning spring 415 abuts against the pressing block 413, and the other end of the positioning spring 415 abuts against one side of the inner surface of the pressing groove 4122. In addition, specifically, the cap 412 is provided with a rotating hole that matches the fixed shaft 4113. The cap 412 is rotatably sleeved on the fixed shaft 4113 through the rotating hole. A limiting screw is threaded on the fixed shaft 4113 to limit the cap 412, so as to prevent the cap 412 from disengaging from the fixed shaft 4113, thereby facilitating the rotatable connection between the cap 412 and the fixed shaft 4113. ,

[0031] By employing the above structure, when it is necessary to rotate the cap 412, the pressing block 413 can be pressed first, causing it to retract into the pressing groove 4122. This causes the positioning block 414 to retract into the positioning groove 4123, disengaging the tip of the positioning block 414 from the positioning tooth ring 4111. At this point, the cap 412 can be rotated. After rotating to the appropriate position, the pressing block 413 can be released. At this time, the elastic force of the positioning spring 415 will... When pressed, the pressing block 413 can be pushed outward, causing the tip of the positioning block 414 to re-engage with the positioning tooth ring 4111, thereby providing a corresponding positioning function for the cap 412. Specifically, when it is necessary to remove the upper 2 from the shoe, the pressing block 413 can be pressed while the cap 412 is rotated, thereby causing the rope winding block 4121 to loosen the two pull ropes 43. At this time, in conjunction with the elastic force applied by the multiple return springs 42, it can drive the... The multiple locking levers 32 on the pull cord 43 move away from the insert block 33, causing the locking levers 32 to disengage from the corresponding locking holes 331 on the insert block 33. This allows for simultaneous control of the separation of multiple locking mechanisms 3, releasing the locking and fixing between the upper 2 and the sole 1. When a new upper 2 needs to be fixed, the new upper 2 can be placed on the upper end of the sole 1, and the multiple insert blocks 33 on the upper 2 can be inserted into the corresponding slots 11 on the sole 1. Then, press... While pressing the block 413, the cap 412 is rotated, thereby driving the winding block 4121 to wind the two pull ropes 43. At this time, the multiple locking rods 32 on the pull rope 43 can be moved to the side closer to the insertion block 33, and the locking rods 32 can be locked into the corresponding locking holes 331 on the insertion block 33. Thus, multiple locking mechanisms 3 can be controlled to lock and fix the upper 2 and the sole 1, making the operation simpler and more convenient.

[0032] In addition, a guide tube 44 is fixedly provided in the rope channel, and the pull rope 43 is passed through the guide tube 44. The longitudinal section of the guide tube 44 is U-shaped, which can guide the movement of the pull rope 43 and better ensure the smoothness of the movement of the pull rope 43.

[0033] In addition, an ankle support piece 12 is fixedly provided on the upper rear side of the sole 1. The cross-section of the ankle support piece 12 is U-shaped. Both sides of the ankle support piece 12 are detachably connected to the upper 2 through connectors 5. In this way, the stability of the connection between the upper 2 and the sole 1 can be further improved. Correspondingly, the connectors 5 are Velcro or multiple metal snaps.

[0034] In addition, V-shaped notches are provided on both the left and right sides of the ankle wrap 12. An elastic sheet 121 is fixedly connected to the ankle wrap 12 at the V-shaped notches. Correspondingly, the elastic sheet 121 can be made of elastic band. By utilizing the stretching elastic deformation of the elastic sheet 121, the size of the opening at the upper end of the ankle wrap 12 can be adjusted to further improve the convenience of putting on and taking off shoes.

[0035] Furthermore, the bottom of the upper 2 is closed and forms a closed bottom surface 21. The upper rear end of the upper 2 is provided with an opening 22. The upper 2 is provided with a separable insole 6. The bottom end of the closed bottom surface 21 is fixedly provided with multiple inserts 211. The upper surface of the sole 1 is provided with multiple grooves 13 that are adapted to and correspond one-to-one with the inserts 211. The inserts 211 are separably embedded in the grooves 13 and can be magnetically fixed to the sole 1. In this way, the stability of the connection between the upper 2 and the sole 1 can be further improved.

[0036] Correspondingly, magnetic rubber sheets are fixedly bonded to both the insert 211 and the groove 13 of the sole 1, thereby facilitating the magnetic attraction between the insert 211 and the sole 1.

[0037] In addition, an annular sealing strip is fixedly provided at the four periphery of the bottom end of the closed bottom surface 21, and an annular sealing groove corresponding to and adapted to the annular sealing strip is provided at the four periphery of the upper end of the shoe sole 1. The annular sealing strip is detachably embedded in the annular sealing groove.

[0038] The above are merely some specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept shall be considered as infringing upon the protection scope of the present invention.
