Description

Technical Field

[0001] This application relates to the technical field of shoe structures, and more particularly, to a telescopic shoe plate structure. Background Art

[0002] Roller skating in a straight line has become a quite popular sport in recent years, especially among young people. The general inline skate structure mainly consists of fixing and assembling a shoe cover above an inline wheel set. In order to adapt to the foot shapes of different users, some telescopic shoe plate structures have structures for adjusting the length and width respectively. However, the structures for adjusting the length and width are separate and must be adjusted separately with hand tools, which is quite inconvenient.

[0003] Among them, as shown in the patent case of the screw-type length adjustment structure for inline skates of Patent No. TW435255U, it mainly consists of a telescopic shoe plate structure body and a shoe cover. A threaded portion is fixedly provided at the bottom of the shoe cover, a screw is provided below the telescopic shoe plate structure body, a knob is provided at the outer end of the screw, positioning grooves are formed at intervals on the periphery of the knob, a pivot piece is pivotally provided on the inline wheel body, and a positioning block that can be engaged with the positioning grooves is formed at the end of the pivot piece. By rotating the knob and driving the screw to rotate, the threaded portion drives the shoe cover to translate, so as to adjust the length between the shoe cover and the telescopic shoe plate structure body. And positioning the positioning block on the pivot piece in the positioning grooves on the knob can keep the shoe cover and the telescopic shoe plate structure body at a fixed length. In this way, the length can be adjusted by rotating the knob from the outside of the telescopic shoe plate structure, and it has the advantage of being convenient to adjust without the need for hand tools.

[0004] Another example is shown in the patent case of the inline skate of Patent No. CN212818025U, which discloses another telescopic structure. It mainly includes an inline skate body and a shoe cover. The shoe upper of the shoe cover has a middle part. When the inline skate body and the shoe cover are relatively stretched straight, the first wing part on the shoe upper expands laterally relative to the middle part through the first structure, and the second wing part on the shoe upper expands laterally relative to the middle part through the second structure, and the first wing part and the second wing part move laterally in opposite directions. In this way, when the inline skate body and the shoe cover are relatively stretched straight, the length and width of the inline skate can be adjusted simultaneously through the reverse expansion of the two wing parts and the positioning of a clamping structure.

[0005] In actual use, both of the above inline skate structures can adjust the length of the inline skates, or adjust the length and width simultaneously, to facilitate users with different foot shapes. However, in the TW435255U patent case, the threaded portion is fixed at the bottom of the shoe cover, and the screw rod is fixed below the telescopic shoe plate structure body. That is to say, the screw rod type length adjustment structure and the inline skates are combined into a single integral body; while in the CN212818025U patent case, the inline skate body and the shoe cover are separated from an integral body into two relatively telescopic individuals. In this way, since one style of inline skates requires a matching telescopic structure, when purchasing, users will be limited by the overall style of the inline skates and cannot separately select different inline skates with the same telescopic structure according to personal preferences.

[0006] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to those of ordinary skill in the art.

[0030] The telescopic shoe plate structure of the present application is for accommodating and connecting and positioning within the internal space of a roller shoe, and mainly includes an upper shoe plate and a lower shoe plate. The upper shoe plate has an upper guiding portion on its plate surface. The longitudinal direction of the upper shoe plate has a front end portion and a rear end portion. One side of the front end portion has a first moving portion, and the other side of the front end portion has a second moving portion. The rear end portion has an upper fastening member. The upper shoe plate is combined with a pushing member. The lower shoe plate has a lower guiding portion on its plate surface, and the lower guiding portion is for connecting with the upper guiding portion. The lower shoe plate has a lower fastening member, and the lower fastening member is for connecting with the upper fastening member. Thereby enabling the upper shoe plate and the lower shoe plate to telescopically move relative to each other to adjust the length, and adjusting the width via the first moving portion and the second moving portion.

[0031] Please refer to Figures 1 to 6As shown, these are some embodiments of the retractable shoe plate structure 1 of the present application, which mainly includes an upper shoe plate 2 and a lower shoe plate 3. The long direction of the upper shoe plate 2 has a front end 21 and a rear end 22. On the plate surface of the front end 21, there is an upper guiding part 211. The upper guiding part 211 includes a straight groove 212 that penetrates the plate surface of the front end 21 up and down, and the long direction of the straight groove 212 is parallel to the long direction of the upper shoe plate 2. On one side of the plate surface of the front end 21, there is a first moving part 23. The first moving part 23 includes a first arc-shaped elastic piece 231. There is a first notch 232 between the first arc-shaped elastic piece 231 and one side of the plate surface of the front end 21, so as to allow the first arc-shaped elastic piece 231 to generate elastic lateral expansion. During implementation, it can also generate elastic lateral expansion or contraction at the same time. On the other side of the plate surface of the front end 21, there is a second moving part 24. The second moving part 24 includes a second arc-shaped elastic piece 241. There is a second notch 242 between the second arc-shaped elastic piece 241 and the other side of the plate surface of the front end 21, so as to allow the second arc-shaped elastic piece 241 to generate elastic lateral expansion. During implementation, it can also generate elastic lateral expansion or contraction at the same time. The rear end 22 has an upper fastening part 221. The upper fastening part 221 includes a long strip-shaped positioning rack 222 that protrudes downward from the plate surface of the rear end 22, and the long direction of the positioning rack 222 is parallel to the long direction of the upper shoe plate 2. On one side of the plate surface of the rear end 22, a square short column protrudes downward, and this square short column serves as the second straight rod part 223.

[0032] The lower shoe plate 3 has a flat plate part 31. The bottom of the flat plate part 31 has a flat surface part 32. The outer peripheral edge of the flat plate part 31 extends upward to form a vertical surface part 33. Thus, when the upper shoe plate 2 and the lower shoe plate 3 are combined together and simultaneously accommodated in the internal space of a roller skate, the flat surface part 32 of the lower shoe plate 3 can be pressed downward for positioning, and a user's foot can be limited within the vertical surface part 33, allowing the user to engage in roller skating. There is a positioning guide groove 331 that penetrates horizontally on the vertical surface part 33. On the plate surface of the lower shoe plate 3, there is a first straight rod part 341 that protrudes upward. The first straight rod part 341 passes upward through the straight groove 212, and the top end of the first straight rod part 341 is locked and connected to a headed screw, and this headed screw serves as the first limiting member 342. Thus, the moving direction of the first straight rod part 341 can be restricted, and the front end 21 of the upper shoe plate 2 can be limited to prevent the front end 21 from separating from the flat plate part 31 of the lower shoe plate 3. During implementation, the first straight rod part 341 and the first limiting member 342 are combined to form a lower guiding part 34.

[0033] On the plate surface of the flat plate portion 31, there is a long guide groove 35 that penetrates the flat plate portion 31 up and down. When the upper shoe plate 2 is stacked above the flat plate portion 31, one end of the second straight rod portion 223 passes downward through the long guide groove 35 and then is locked to a pushing portion 224. During implementation, the second straight rod portion 223 and the pushing portion 224 are combined into a pushing member 225. Additionally, below the rear plate surface of the flat plate portion 31, there is a lower fastening member 36. The lower fastening member 36 includes a clamping member 37 and a reset member 38. The clamping member 37 is a long cylinder with a head 371 at one end. The head 371 of the clamping member 37 is limited within the positioning guide groove 331 of the vertical plate portion 33. The other end of the clamping member 37 has a positioning tooth 372, and the positioning tooth 372 correspondingly clamps the positioning rack 222 of the upper shoe plate 2. The reset member 38 is a compression spring. The reset member 38 is positioned within the lower shoe plate 3, and one end of the reset member 38 is coaxially connected to the other end of the clamping member 37 to stably position the clamping member 37 and enable the clamping member 37 to return to its original position after movement.

[0034] Above the rear plate surface of the flat plate portion 31, there is a second limiting member 39. The second limiting member 39 has a pressing plate 391 in the shape of a long sheet. Below the plate surface of the pressing plate 391, there are two parallel downward protruding positioning posts (392, 392'), and these two positioning posts (392, 392') are combined into a first engaging portion 393. One end of each of the two positioning posts (392, 392') is inserted into two positioning holes (311, 311') of the flat plate portion 31, so as to limit the two positioning posts (392, 392') by corresponding to the two positioning holes (311, 311'), and enable the pressing plate 391 to press downward against the rear end portion 22 of the upper shoe plate 2 to prevent the rear end portion 22 from separating from the flat plate portion 31 of the lower shoe plate 3. During implementation, the two positioning holes (311, 311') are combined into a first engaging portion 312.

[0035] Thus, when the user presses the head 371 at one end of the clamping member 37, the positioning tooth 372 can be separated from the positioning rack 222, enabling the upper shoe plate 2 and the lower shoe plate 3 to form a state where they can relatively telescopically extend and contract directly. When the pushing member 225 is pushed to move the upper shoe plate 2 and then the head 371 is released, the positioning tooth 372 and the positioning rack 222 can return to a state of being mutually clamped, thereby enabling the upper shoe plate 2 and the lower shoe plate 3 to have a fixed length to suit the length of a foot of different users. And through the reverse elastic expansion or contraction of the first arc-shaped elastic piece 231 and the second arc-shaped elastic piece 241, it can be suitable for the width of a foot of different users, facilitating the use by users with different foot lengths and widths.

[0036] In summary, based on the content disclosed above, this application can indeed achieve the intended purpose, providing a telescopic shoe plate structure that can not only accommodate and connect a top shoe plate and a bottom shoe plate within the internal space of a roller skate, enabling users to flexibly choose and match roller skates with different appearance styles according to their personal preferences, but also adjust according to the different lengths and widths of the users' feet. It has great industrial utilization value, so a utility model patent application is filed in accordance with the law.
