Description

Technical field:

[0001] The invention relates to a foldable height-reducing roller skate, belonging to the technical field of sports goods. Background technology:

[0002] More than a hundred years ago, a pair of four-wheeled skates with wheels side by side appeared, which could make various movements such as turning, moving forward and backward. This is the prototype structure of the most popular roller skates now. At present, most roller skates are single roller skates, and the wheels are fixed on the aluminum alloy base, because the aluminum alloy base is relatively strong and not easy to deform. The matching wheels must be highly elastic wheels, and must not be plastic wheels. Generally, the high elastic wheels are relatively soft and have good elasticity. The roller skates matched with them are durable. Although roller skates can be widely used, they can only be used in the process of roller skating. With the widespread popularity of roller skating, there are more and more places where roller skating can be performed, but the process of replacing roller skates is still very inconvenient. Users need to bring two sets of shoes for replacement. There is an urgent need for the emergence of multi-purpose roller skates. At present, the internal structure design of shoes that can be converted between ordinary shoes and roller skates is complex and prone to failure. In addition, the wheel output method is single, and the height of the wheel is in the same direction as the height of the shoe, resulting in the wheel being fixed in the direction and the height cannot be ignored when it is inside the shoe. In order to take into account the height of the wheel, the total height of the shoe is significantly higher than the height of the ordinary shoe. When walking normally, it forms a "walking on stilts" walking method, which is uncomfortable to wear and more unfavorable for stable walking. When gliding, it is generally used by skilled personnel who can only slide in the forward and backward directions, and cannot meet the versatility of learning training and technical tricks for beginners. Summary of the invention:

[0003] In order to solve the problems mentioned in the above background technology, the object of the present invention is to provide a foldable height-reducing roller skate.

[0004] A foldable height-reducing roller skate comprises a shoe body and a deformable wheel assembly. A mounting groove is processed on the bottom of the shoe body. The deformable wheel assembly comprises two support rods and at least two pulleys. The two support rods are arranged in the mounting groove along the length direction of the shoe body. One end of each support rod is hinged in the mounting groove. The other end of each support rod is provided with at least one pulley. When the pulley is in the mounting groove, the axial direction of the pulley is in the same direction as the height direction of the shoe body. When the pulley is in a sliding state, the radial direction of the pulley is in the same direction as the height direction of the shoe body.

[0005] As a preferred solution: the support rod includes an outer cover body, a rotating shaft, an inner plug, an insert block, a limit plate, a connecting piece and a spring. The inner plug is arranged in the outer cover body, the rotating shaft is passed through the inner plug, both ends of the rotating shaft pass through the side walls of the outer cover body and are hinged to the side walls of the mounting groove respectively, a socket is processed at the lower end of the inner plug, a limit plate is fixedly mounted on the insert block, the upper end of the insert block is detachably connected to the socket, the lower end of the insert block passes through the outer cover body and is integrally connected to the upper end of the connecting piece, the spring is mounted on the insert block and is between the limit plate and the bottom surface of the outer cover body, and at least one pulley is hinged at the lower end of the connecting piece.

[0006] As a preferred solution: the plug block is a special-shaped block, and the plug block includes a square column and a round column, and the square column and the round column are fixedly connected in sequence from top to bottom to form a whole.

[0007] As a preferred solution: the bottom end of the connecting piece is processed with a connecting part that matches the pulley one by one. When the number of pulleys is one, the connecting piece is a connecting rod, and the bottom end of the connecting rod is processed with a connecting part. When the number of pulleys is two, the longitudinal cross-section of the connecting piece along its length direction is a triangle, and the two end corners at the bottom of the connecting piece are two connecting parts.

[0008] As a preferred solution: one end of each support rod is hinged to the inner wall of the end of the installation groove.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. The present invention changes the folding method of the existing wheels, so that the support rod and the pulley in the deformable wheel assembly cooperate with each other to realize the pulley to expand and fold under the drive of the support rod, and can also realize a 90-degree twisting action under the cooperation between the outer cover, the rotating shaft, the inner plug, the plug block, the limit plate, the connecting piece and the spring, thereby driving the pulley to twist after expansion or before folding, thereby directly taking into account the technical effects of the fixed height of the pulley itself that does not need to be changed and the ability to reduce the total height of the shoe, overcoming the difficult problem of reducing the total height of the shoe under the premise of keeping the height of the pulley itself unchanged, making the structure of the roller skates and ordinary shoes more coordinated with each other more reasonable and simple, and the deformation operation is stable and reliable.

[0011] Second, the present invention has multiple functions. Function one is that it can be used as ordinary shoes, and function two is that it can be used as roller skates. When used as roller skates, it can achieve the effects of forward movement and sideways sliding, and can also help beginners practice standing posture.

[0012] 3. The present invention realizes continuous changes of multiple actions of the pulley through a simple structure formed by a support rod, and the operation is fast and the position is stable after deformation. Description of the drawings:

Specific implementation method:

[0023] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is described below by the specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0024] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the solutions according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0025] Specific implementation method 1: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6, Figure 7 and Figure 8 As shown, this specific embodiment adopts the following technical scheme, which includes a shoe body 1 and a deforming wheel assembly 2. The bottom of the shoe body 1 is processed with a mounting groove 3. The deforming wheel assembly 2 includes two support rods 6 and at least two pulleys 7. The two support rods 6 are arranged in the mounting groove 3 along the length direction of the shoe body 1. One end of each support rod 6 is hinged in the mounting groove 3. The other end of each support rod 6 is provided with at least one pulley 7. When the pulley 7 is in the mounting groove 3, the axial direction of the pulley 7 is in the same direction as the height direction of the shoe body 1. When the pulley 7 is in a sliding state, the radial direction of the pulley 7 is in the same direction as the height direction of the shoe body 1.

[0026] The axial direction of the pulley of the present invention is not unique, and can be in the same direction as or perpendicular to the width direction of the shoe body, such as Figure 4 As shown, the present invention can slide forward and backward. Figure 2 As shown, the present invention can also slide sideways. Figure 3 As shown, when the axial directions of the two pulleys 7 at the front and rear positions are perpendicular to each other, it is more stable for beginners to stand, which can train the strength of the beginners' ankle joints and is more conducive to use by beginners.

[0027] In this embodiment, the shape of the mounting groove 3 matches the shape of the deformable wheel assembly 2 .

[0028] Furthermore, the mounting groove 3 includes a plurality of single grooves 3-1, and the single grooves 3-1 are arranged one-to-one corresponding to the support rods 6. Each single groove 3-1 is detachably connected to its corresponding support rod 6, and the shape of each single groove 3-1 matches the shape of the structure composed of its corresponding support rod 6 and the pulley 7 on the support rod 6.

[0029] In this embodiment, when the deformable wheel assembly 2 is in the folded state, that is, the two support rods 6 and at least two pulleys 7 are all stored in the installation groove 3, the performance of the shoe body 1 at this time is the performance of an ordinary walking shoe.

[0030] Furthermore, when the deformable wheel assembly 2 is in the unfolded state, that is, the two support rods 6 and at least two pulleys 7 are unfolded and located below the mounting groove 3, the performance of the shoe body 1 at this time is the performance of roller skates.

[0031] Specific implementation method 2: This implementation method is a further limitation of specific implementation method 1. The support rod 6 includes an outer cover body 6-1, a rotating shaft 6-2, an inner plug 6-3, an insert block 6-4, a limiting plate 6-5, a connecting member 6-6 and a spring 6-7. The inner plug 6-3 is arranged in the outer cover body 6-1, and the rotating shaft 6-2 is penetrated on the inner plug 6-3. The two ends of the rotating shaft 6-2 pass through the side walls of the outer cover body 6-1 and are hinged to the side walls of the groove of the mounting groove 3 respectively. A socket 6-8 is processed at the lower end of the inner plug 6-3. A limiting plate 6-5 is fixedly mounted on the insert block 6-4. The upper end of the insert block 6-4 is detachably connected to the socket 6-7. The lower end of the insert block 6-4 passes through the outer cover body 6-1 and is integrally connected to the upper end of the connecting member 6-6. The spring 6-7 is mounted on the insert block 6-4 and is located between the limiting plate 6-5 and the bottom surface of the outer cover body 6-1. The lower end of the connecting member 6-6 is hinged with at least one pulley 7.

[0032] In this embodiment, the interior of the outer cover 6-1 provides accommodation space for the rotating shaft 6-2, the inner plug 6-3, the plug block 6-4, the limit plate 6-5 and the spring 6-7, and can also ensure that the longitudinal space of the spring 6-7 is effectively limited when the plug block 6-4 rotates, and can also provide a spatial position for the lateral twisting action of the spring 6-7, so that the plug block 6-4 can make a 90-degree rotation while driving the pulley 7 to make a synchronous action through the connecting member 6-6, so that the pulley 7 can be turned from a parallel state to a vertical state relative to the bottom surface of the shoe body 1, thereby completing the conversion of the pulley 7 from a storage state to a use state.

[0033] In this embodiment, the spring 6-7 is in a primary compression state before twisting, and during the 90-degree twisting process, the spring 6-7 is compressed for a second time on the basis of the primary compression state. After ensuring that the top of the plug 6-4 is completely out of the socket 6-8, the plug 6-4 is rotated horizontally at an angle of 90 degrees. After rotating 90 degrees, the plug 6-4 is released, and the spring 6-7 is converted from the secondary compression state to the primary compression state. The plug 6-4 is inserted into the socket 6-8 for the second time, completing the 90-degree rotation process of the plug 6-4. The rotation of the plug 6-4 causes the connecting member 6-6 to rotate, thereby driving the pulley 7 to make a synchronous rotation action.

[0034] Specific implementation method three: This implementation method is a further limitation of specific implementation methods one or two. The plug block 6-4 is a special-shaped block. The plug block 6-4 includes a square column 6-4-1 and a round column 6-4-2. The square column 6-4-1 and the round column 6-4-2 are fixedly connected in sequence from top to bottom as a whole.

[0035] In this embodiment, the plug block 6-4 is a special-shaped block, specifically a structure composed of a square column 6-4-1 and a round column 6-4-2, which is an upper and lower round structure. The shape of the square column 6-4-1 is to match the shape of the socket 6-8 in the inner plug 6-3, so that the two can be plugged in quickly and smoothly.

[0036] Furthermore, the shape of the circular cylinder 6-4-2 is designed to cooperate with the spring 6-7, so that the transition of the spring 6-7 from the first compression to the second compression is smooth and unobstructed.

[0037] Furthermore, the transverse cross-section of the square column 6-4-1 is a square, that is, the corresponding shape of the plug hole 6-8 is a square hole.

[0038] Specific implementation method 4: This implementation method is a further limitation of specific implementation methods 1, 2 or 3, and the ratio of the length of the square cylinder 6-4-1 to the length of the circular cylinder 6-4-2 is 1:3.

[0039] This ratio is the optimal length ratio determined during the design and development process, which is conducive to providing sufficient space for the twisting operation of the support rod 6 and can also ensure the basic height of the roller skates.

[0040] Specific embodiment five: This embodiment is a further limitation of specific embodiments one, two, three or four. The bottom end of the connecting member 6-6 is processed with a connecting portion 8 that matches the pulley 7 one by one. When the number of pulleys 7 is one, the connecting member 6-6 is a connecting rod, and the bottom end of the connecting rod is processed with a connecting portion 8. When the number of pulleys 7 is two, the longitudinal cross-section shape of the connecting member 6-6 along its length direction is a triangle, and the two end corners at the bottom of the connecting member 6-6 are two connecting portions 8.

[0041] Furthermore, when there are two pulleys 7, the longitudinal cross-sectional shape of the connecting member 6-6 along its length direction is preferably an isosceles triangle.

[0042] Specific implementation example six: This implementation example is a further limitation of specific implementation examples one, two, three, four or five, in which the upper end of each support rod 6 is hinged to the inner wall of the end of the mounting groove 3 .

[0043] Specific embodiment seven: This embodiment is a further limitation of specific embodiments one, two, three, four, five or six. At least one protrusion is processed on the outer wall of the outer cover body 6-1, and a slot matching the protrusion is processed on the side wall of the mounting groove 3. The protrusion and the slot are snap-fitted to achieve a locking effect of fixing the deformable wheel assembly 2 when the shoe body 1 is in the storage state.

[0044] Furthermore, the protrusion is an elastic protrusion made of existing rubber or plastic.

[0045] Specific embodiment eight: This embodiment is a further limitation of specific embodiments one, two, three, four, five, six or seven. In this embodiment, the optimal number of support rods 6 is two, and the number of pulleys 7 provided on each support rod 6 is two.

[0046] Furthermore, the two support rods 6 are arranged one in front of the other in the length direction of the shoe body 1, and the operation order of the two support rods 6 is not limited, and the front support rod 6 can be operated first, and then the rear support rod 6. Alternatively, the rear support rod 6 can be operated first, and then the front support rod 6 can be operated.

[0047] Furthermore, the shoe body 1 can be an existing shoe body, and there is no need to perform any additional structural processing to increase the height of the shoe body 1 .

[0048] Specific embodiment nine: This embodiment is a further limitation of specific embodiments one, two, three, four, five, six, seven or eight. In this embodiment, the shaft 6-2 is an existing right-angle shaft, and the angle between the two extreme rotation limits of the shaft 6-2 is 90 degrees, ensuring that the rotation limit positions of the inner plug 6-3, the plug block 6-4 and the connector 6-6 can accurately reach 90 degrees. The auxiliary design of the relevant positioning components is eliminated, so that the structure of the deformation wheel assembly 2 is simple and compact, saving the occupied area and space, which is conducive to reducing the total height of the shoe body 1 when used for roller skates, and can also reduce the occupied height of the deformation wheel assembly 2 when it is in the storage state.

[0049] Specific embodiment ten: This embodiment is a further limitation of specific embodiments one, two, three, four, five, six, seven, eight or nine. When there are multiple connecting parts 8 on the connecting member 6-6, reinforcing ribs 6-9 are provided on the connecting member 6-6 to strengthen the self-compressive and tensile strengths of the connecting member 6-6.

[0050] Further, when the connecting member 6 - 6 has two connecting portions 8 , the shape of the reinforcing rib 6 - 9 matches the edge shape of the connecting member 6 - 6 .

[0051] Further, when the connecting member 6 - 6 has two connecting portions 8 , the reinforcing rib 6 - 9 is preferably in the shape of an arc-shaped bar.

[0052] Working process:

[0053] The operation process of converting ordinary walking shoes into roller skates of the present invention is divided into a 90-degree turning operation of the deformable wheel assembly 2 and a 90-degree turning operation of the pulley 7.

[0054] The 90-degree turning operation of the deformable wheel assembly 2 is as follows:

[0055] Grasp the support rod 6 with your hand, and apply force to rotate the support rod 6 from the horizontal position parallel to the bottom of the mounting groove 3 to the vertical position through the mounting groove 3 at the bottom of the shoe body 1. That is, the connecting member 6-6 rotates 90 degrees driven by the rotating shaft 6-2, thereby driving the pulley 7 to rotate synchronously. After the above process is completed, the axial direction of the pulley 7 is in the same direction as the length direction of the shoe body 1.

[0056] Then the pulley 7 is further turned 90 degrees:

[0057] Since the spring 6-7 is in a primary compression state before twisting, the downward pulling connecting piece 6-6 causes the plug 6-4 to move downward in the outer cover 6-1, and at the same time, the compression spring 6-7 is in a secondary compression state, until the top of the plug 6-4 is completely out of the socket 6-8, the plug 6-4 is rotated horizontally, the rotation angle is 90 degrees, and the plug 6-4 is released after rotating 90 degrees. The spring 6-7 is converted from the secondary compression state to the primary compression state, and the plug 6-4 is inserted into the socket 6-8 for the second time, completing the 90-degree rotation process of the plug 6-4, that is, the rotation of the plug 6-4 drives the pulley 7 to make a synchronous rotation action through the connecting piece 6-6, so that the pulley 7 is in use, that is, the rolling direction of the pulley 7 is in the same direction as the length direction of the shoe body 1.

[0058] The operation process of converting roller skates into common walking shoes is the reverse operation of the above process.

[0059] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
