Technical Field

[0001] The invention belongs to the technical field of detachable footwear, and in particular relates to a detachable roller skating structure, roller skates and a wearing method of the roller skates. Background Art

[0002] There are two types of roller skates on the market, single-row and double-row. Most of them are one-piece designs, which are inconvenient to wear or carry. Usually, you need to wear a pair of shoes and bring a pair of roller skates, which cannot be switched at any time. In addition, one-piece roller skates are bulky and inconvenient to carry. There is a type of shoe with a thick insole and wheels hidden inside. The wheels can be opened when in use. This type of shoe can be used for short-distance skating, but because of its thick sole, small wheel spacing between the pulleys, and thin pulleys, the skating speed is slow and the skating is unstable, and it is impossible to get a real skating experience like roller skates. There is also a type of shoe that designs the sole of the skates into a detachable structure, but the other disassembly and installation processes are complicated, and it is not possible to install it conveniently on site. Summary of the invention

[0003] In order to solve the problems in the above-mentioned background technology, the present invention provides a detachable roller skating structure, roller skates and a method for wearing roller skates. The present invention enables the sole structure to be more conveniently and quickly removed or installed from the sole of an ordinary shoe by moving the lock buckles on the locking mechanism toward or away from each other, thereby realizing free and arbitrary switching between ordinary shoes and roller skates.

DETAILED DESCRIPTION

[0039] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0040] The following is combined with Figure 1 To Attachment Fig.11 The present invention is described in detail with reference to specific embodiments.

[0041] like Figure 1-11 As shown, the present invention provides a detachable roller skating structure for being installed on the sole of an ordinary shoe, so that the ordinary shoe and the roller skating structure can be quickly installed and quickly separated, thereby realizing free switching between the ordinary shoe and the roller skating shoe. The ordinary shoe can be worn alone for walking or other sports, and the ordinary shoe can be a sports shoe, a skate shoe, a leather shoe, etc., but is not limited to this. It should be understood that a locking card plate that matches the roller skating structure is provided on the sole of the ordinary shoe, and the locking card plate can be used to achieve quick installation and disassembly with the roller skating structure.

[0042] The sole structure of the present application includes a frame 1, a locking mechanism 2 and a toggle switch 5, wherein a receiving cavity 11 extending along the length direction is provided in the frame 1, and the receiving cavity 11 is a cavity with an upper end opening; the locking mechanism 2 is installed in the receiving cavity 11, and the locking mechanism 2 includes two lock buckles 21 and a driving component 22 located between the two lock buckles 21, and the driving component 22 drives the two lock buckles 21 to move toward or away from each other to open the lock buckles 21 or lock the lock buckles 21 on the sole of the ordinary shoe, and the two lock buckles 21 are respectively located at the two ends of the length direction of the receiving cavity 11 and extend upward from the receiving cavity 11, and the lock buckles 21 are used to lock and separate with the sole of the ordinary shoe, and when the two lock buckles 21 move toward each other, the lock buckles 21 are in the opening process or the open state, and at this time, the ordinary shoe can be removed from the roller skating structure; when the two lock buckles 21 move away from each other, the lock buckles 21 can lock the roller skating structure on the sole of the ordinary shoe, so as to realize the switching use of the roller skates, thereby realizing the dual-use effect of the roller skates. The toggle switch 5 is arranged on the outside of the frame 1 and is in transmission connection with the driving assembly 22. The toggle switch 5 includes a toggle housing 51 and a limit lock arranged on the toggle housing 51. The limit lock can be locked on the frame 1. The toggle switch 5 is arranged on the outside of the frame 1, which is convenient for the user to operate. When the user uses it, the limit lock on the toggle switch 5 can be opened to allow the toggle switch 5 to rotate freely, and drive the driving assembly 22 to move. The movement of the driving assembly 22 drives the lock buckle 21 to move horizontally, thereby realizing the locking and unlocking of the lock buckle 21. At the same time, the setting of the limit lock can ensure that the relative position of the lock buckle 21 is fixed during the use of the roller skates, ensuring the safety during the skating process.

[0043] The present application designs the roller skating structure into a separately detachable integral structure by providing a skeleton 1, a locking mechanism 2 and a toggle switch 5. When not in use, the roller skating structure can be disassembled and placed in the user's backpack. Since the separate roller skating structure is small in size and light in weight, it is more convenient to carry. The functions of ordinary shoes are the same as those of ordinary shoes, and the shoes can continue to be worn for other sports or ordinary walking. When skating is to be performed, the roller skating structure can be taken out and installed and locked on the sole of the ordinary shoe being worn to achieve the switching of roller skates. The roller skating structure of the present application is not only easy to carry, easy to install, and has high safety performance, but also realizes the real gliding experience of roller skates.

[0044] For details, see Figure 5The accommodating cavity 11 of the present application includes a first cavity 111, a second cavity 112 and a third cavity 113 which are sequentially connected along the length direction of the frame 1. Two lock buckles 21 are respectively located in the first cavity 111 and the third cavity 113. The driving component 22 is located in the second cavity 112, and the telescopic end of the driving component 22 extends into the first cavity 111 and the third cavity 113 and is fixedly connected to the lock buckle 21 through a stop pin 223. The locking mechanism 2 can be placed in the accommodating cavity 11 from the upper opening of the accommodating cavity 11, which simplifies the installation process, so that the locking mechanism 2 is first installed outside the frame 1 and then placed as a whole in the accommodating cavity 11. It can be understood that the space of the accommodating cavity 11 of the present application is small, and the size of each cavity is only suitable for assembling the parts adapted thereto. Therefore, it is not suitable to assemble the locking mechanism 2 in the accommodating cavity 11.

[0045] For details, see Figure 3 , Figure 4 , Fig.10 and Fig.11 The locking mechanism 2 also includes a reset elastic member 4, each lock buckle 21 corresponds to a reset elastic member 4; the two reset elastic members 4 are respectively located in the first cavity 111 and the third cavity 113, one end of one reset elastic member 4 abuts against the corresponding lock buckle 21, and the other end abuts against the inner wall of the first cavity 111, and one end of the other reset elastic member 4 abuts against the corresponding lock buckle 21, and the other end abuts against the inner wall of the third cavity 113. When the lock buckle 21 is locked, the reset elastic member 4 is in a compressed state. In other words, the lock buckle 21 can move the two lock buckles 21 in opposite directions under the action of the reset elastic member 4. During the movement of the lock buckle 21, the limit lock will also be driven to reset to the locked position, and the limit lock will be locked on the frame 1, so that the roller skating structure is automatically locked on the sole of the ordinary shoe, which saves the installation procedure and improves the convenience of installation. Preferably, the reset elastic member 4 is a spring.

[0046] For details, see Figure 4 , Fig.11The driving assembly 22 includes a toggle cap 221, and a toggle piece 222 is provided on each side of the toggle cap 221. The toggle cap 221 is transmission-connected to the toggle piece 222. The end of the toggle piece 222 away from the toggle cap 221 is connected to the lock buckle 21. The reset elastic member 4 is sleeved on the toggle piece 222. The toggle piece 222 can provide guidance for the direction of the force of the reset elastic member 4 to prevent the reset elastic member 4 from bending; the toggle cap 221 is rotated, and the toggle cap 221 drives the lock buckle 21 to move horizontally through the toggle piece 222. In the present embodiment, one of the connection methods between the toggle member 222 and the lock buckle 21 is: a socket is provided on the lock buckle 21, one end of the toggle member 222 is inserted into the socket, and a stop pin hole is penetrated on the toggle member 222 and the lock buckle 21, and a stop pin 223 is installed in the stop pin hole to achieve relative fixation of the toggle member 222 and the lock buckle 21, but it is not limited to this. As long as the relative fixation of the toggle member 222 and the lock buckle 21 can be achieved, it belongs to the protection scope of this application.

[0047] In some embodiments, see Fig.10 , Fig.11The toggle cap 221 includes a guide cylinder (not shown) and a toggle sleeve 2211 spaced apart on the guide cylinder, symmetrically arranged protrusions 2212 are formed on the toggle sleeve 2211, one end of the toggle member 222 is overlapped on the guide cylinder and located between the protrusions 2212 of the two toggle sleeves, and an abutment block 2221 in contact with the protrusion 2212 of the toggle sleeve is provided on the toggle member 222. The toggle sleeve 2211 rotates so that the protrusion 2212 interacts with the abutment block 2221 to drive the toggle member 222 to move horizontally on the top of the guide cylinder; when When the lock buckle 21 is in the locked state, the toggle cap 221 can be rotated in the opposite direction to rotate the protrusion 2212 of the toggle sleeve to the end of the abutment block 2221 away from the corresponding lock buckle 21, which can limit the backward movement of the toggle member 222, thereby preventing the pulley structure from detaching from the sole of an ordinary shoe under the action of external force during the use of the roller skates, thereby causing safety problems. In addition, in order to further prevent the toggle member 222 from moving backward during the sliding process of the roller skates, a movable limiting assembly is provided on the toggle member 222 and the frame 1, which can effectively improve the safety of the roller skates during the sliding process. In one embodiment, the movable limiting assembly includes a plug-in shaft 226, and both the toggle member 222 and the frame 1 are provided with a socket that cooperates with the plug-in shaft 226, and when the position of the socket on the frame 1 is locked with the lock buckle 21, the socket on the toggle member 222 corresponds to the socket. When the soles of ordinary shoes and roller skates are locked, the plug-in shaft 226 is passed through the sockets on the toggle member 222 and the frame 1 to limit the toggle member 222, so that the toggle member 222 cannot move backward, thereby achieving double safety protection. In another embodiment, the movable limiting assembly is limited in the form of a gear rack (not shown in the figure), such as processing a rack structure on the toggle member, and opening a guide clamping groove on the side wall of the skeleton, in which a gear assembly or a ratchet assembly is movably arranged, and the engagement with the rack is achieved by changing the position of the gear and the ratchet to prevent the gear from moving backward; of course, in other embodiments, the movable limiting assembly may also adopt other structures, as long as the toggle member can be limited to prevent it from moving backward, it belongs to the protection scope of the present application.

[0048] In some other embodiments, see Figure 3 , Figure 4, the toggle cap 221 is connected to the toggle member 222 through the connecting rod 224, one end of the connecting rod 224 is hingedly connected to the toggle cap 221, and the other end is hingedly connected to the toggle member 222. When the toggle cap 221 rotates, the rotation of the toggle cap 221 drives the connecting rod 224 to move in conjunction, and the connecting rod 224 pulls the toggle member 222 to move horizontally. When the lock buckle 21 is in a locked state, the relative positions of the toggle cap 221, the connecting rod 224, and the toggle member 222 are fixed, and the toggle member 222 is restricted from moving backward; preferably, when the lock buckle 21 is in a locked state, the connecting rod 224 and the toggle member 222 are close to a straight line state, and the interaction effect is better. In addition, in order to further prevent the toggle member 222 from moving backward during the sliding process of the roller skates, a movable limit assembly is set on the toggle member 222 and the frame 1, which can effectively improve the safety of the roller skates during the sliding process. In one embodiment, the movable limit assembly includes a plug-in shaft 226, and a plug-in hole matching the plug-in shaft 226 is provided on the toggle member 222 and the frame 1 or on the connecting rod 224 and the frame 1. When the soles of ordinary shoes and roller skates are locked, the plug-in shaft 226 is passed through the toggle member 222 or the connecting rod 224 and the plug-in hole on the frame 1 to limit the toggle member 222, so that the toggle member 222 cannot move backward, thereby achieving double safety protection. In another embodiment, the movable limit assembly adopts a gear rack form (not shown in the figure) for limiting, such as machining a rack structure on the toggle member, and opening a guide clamping groove on the side wall of the frame, and a gear assembly or a ratchet assembly is movably provided in the guide clamping groove, and the meshing with the rack is achieved by changing the position of the gear and the ratchet to prevent the gear from moving backward; of course, in other embodiments, the movable limit assembly can also adopt other structures, as long as the toggle member can be limited to prevent it from moving backward, it belongs to the protection scope of this application.

[0049] For details, see Figure 6 , a pin hole is provided at the axis position of the toggle cap 221, a pin 225 is installed in the pin hole, one end of the pin 225 passes through the frame 1 and is connected to the toggle switch 5 outside the frame 1. When the toggle switch 5 is rotated, the toggle cap 221 is driven to rotate through the pin 225, thereby realizing the horizontal movement of the toggle member 222. The pin hole and the pin 225 of the present application can be in the shape of a quadrilateral, a pentagon, a hexagon, etc., but are not limited thereto, as long as the relative fixation of the two can be achieved. In addition, the toggle switch 5 is a switch with a limit lock, which can realize the rotation of the toggle cap 221 and also limit the rotation of the toggle cap 221.

[0050] For details, see Figure 6The toggle switch 5 includes a toggle housing 51 connected to the pin 225, a locking member 52 movably arranged in the toggle housing 51 along a direction perpendicular to the side wall of the frame 1, and a compression spring 53 arranged between the locking member 52 and the inner wall of the toggle housing 51. A locking hole (not shown in the figure) is provided on the side of the frame 1 opposite to the locking member 51. The end of the locking member 51 away from the compression spring 53 can be inserted into the locking hole under the action of the compression spring 53. The setting position and distribution number of the locking holes in this application need to be designed according to the specific structure of the locking mechanism 2, and are not specifically limited here. It should be noted that when the lock buckle 21 is in a locked state with the ordinary shoe, the locking member 51 is inserted into the locking hole under the action of the compression spring 53, that is, the driving assembly 22 is locked, and the lock buckle 21 will not move during the use of the roller skates; when installing and disassembling the roller skate structure, first pull the locking member 51 to make the locking member 51 disengage from the locking hole, and then rotate the toggle switch 5 to achieve the movement of the lock buckle 21.

[0051] For details, see Figure 1 , Figure 2 A shoe plate 6 is installed on the upper end surface of the frame 1. A through hole is opened on the shoe plate 6. The positioning plate 3 is installed at the position of the through hole. The shape of the shoe plate 6 is the same as the shape of the sole of an ordinary shoe. The shoe plate 6 can cover the upper opening of the accommodating cavity 11 except the position of the lock buckle 21 to prevent dust and other dirt from entering the accommodating cavity. Of course, the present application can also not set the shoe plate 6, design the upper end surface of the frame 1 to match the shape of the sole of an ordinary shoe, and set a covering plate to cover the upper opening of the accommodating cavity 11, and the effect is the same as the above embodiment.

[0052] For details, see Figure 7 , Figure 8 The lock buckle 21 includes a moving part 211 and a hook 212 fixed on the moving part 211. The hook 212 is in a 7-shaped structure, and the two hooks 212 are arranged back to back, that is, the hook-shaped part of the hook 212 is arranged outward, and the top surface of the hook 212 is a first inclined surface 213. The first inclined surface 213 is inclined downward in the direction away from the driving component 22. The angle between the first inclined surface 213 and the horizontal plane is a, and a is an obtuse angle. Applying a force perpendicular to the first inclined surface 213 to the first inclined surface 213 will cause the lock buckle 21 to generate a force to move backward, so that the two lock buckles 21 move toward each other, and then the lock buckle 21 can be opened and ordinary shoes can be installed on the roller skate structure of the present application; in addition, the angle between the back side 214 of the hook 212 away from the hook-shaped part and the horizontal plane is b, and b is greater than or equal to 90°. In order to ensure that the force driving the lock buckle 21 to move backward is large, b is generally greater than 90°. Of course, if Figure 8 As shown, the back side 214 of the hook can also be designed as an arc surface, as long as the angle between the section of the arc surface and the horizontal plane is b, and b is always greater than 90°, but the shape of the back side of the hook is not limited thereto.

[0053] For details, see Fig. 9 When the first inclined surface 213 is subjected to a force F perpendicular to the first inclined surface 213, the first inclined surface 213 can decompose F into F x and F y ,F y The friction force F is generated between the contact surface of the lock buckle 21 and the accommodating cavity 11. f When the lock buckle 21 is locked, the resetting elastic member 4 exerts a forward pressure of F on the lock buckle 21. z , and F z Always greater than F x , the self-locking of the lock buckle 21 can be realized. It should be noted that, in order to increase the safety of the roller skates, the greater the friction force, the better the self-locking property; in order to further increase the friction force, the roughness value of the contact surface between the lock buckle 21 and the accommodating cavity 21 can be appropriately increased, such as Ra12.5 or Ra25; since the force F exerted on the first inclined surface 213 is a variable, F x and F f is also a variable. In the specific design process, the forward pressure exerted by the reset elastic member 4 on the lock buckle 21 can be set to be greater than F x The maximum value can ensure self-locking.

[0054] The present application fully ensures the safety of the roller skates during use by means of the self-locking of the lock, the limit lock on the toggle switch, and the setting of the movable limit assembly in the frame.

[0055] For details, see Figure 1 , Figure 2 The roller skating structure also includes a positioning plate 3, which can be fixed on the frame 1 by fasteners such as bolts, and is located at the upper openings at both ends of the accommodating cavity 11, and is arranged one-to-one with the two lock buckles 21. A limiting hole is provided on the positioning plate 3, and the corresponding lock buckle 21 passes through the limiting hole upward and moves horizontally in the limiting hole. The limiting hole is a strip hole with a certain length, which can enable the lock buckle 21 to move horizontally within a certain range.

[0056] For details, see Figure 2 Each lock buckle 21 is also provided with a stopper card 7 on its side. The stopper card 7 is fixed on the upper surface of the frame 1 and extends upward through the positioning plate 3. The stopper card 7 is used to position the ordinary shoe. Correspondingly, the sole of the ordinary shoe is provided with a locking card 8, and the locking card 8 is provided with a positioning hole 81. When installing the roller skate structure of the present application, the stopper card 7 needs to be aligned with the positioning hole 81 first, so that the sole structure can be accurately installed on the ordinary shoe.
