[0002] Skateboarding is a skill-based sport that involves sliding, jumping, spinning, flipping, and other difficult movements. The main body of a skateboard is a board, and two brackets are installed at the bottom of the board. Both brackets are equipped with axles, and wheels are installed at both ends of the axles. Beginners are prone to uneven force on the board, causing one side of the wheel to rotate and drive the board to tilt, so the person standing on the board is also very likely to lose balance and fall.

[0055] See also Figure 1 and 2 The present embodiment discloses a wheel limiter, comprising a main side plate 1 and two first limiting strips 2 arranged on the main side plate 1 at intervals, one ends of the two first limiting strips 2 are interconnected with the lower part of the main side plate 1, a wheel space is formed between the main side plate 1 and the two first limiting strips 2, the wheel space is used to place the wheels 300 of the skateboard, the main side plate 1 is provided with an installation groove 11, the installation groove 11 is connected to the wheel space, and the installation groove 11 is used to install the axle 200 of the skateboard.

[0056] See Figure 3The installation method of the skateboard and the wheel limiter is to directly clamp the axle 200 of the skateboard into the installation groove 11. In this way, the wheel limiter can be installed on the skateboard without tools, without removing parts of the skateboard or modifying the skateboard in other ways, so as to assist the skateboarder in skateboarding practice. Moreover, by removing the axle 200 from the installation groove 11, the disassembly of the wheel limiter is completed, and the normal operation of the skateboard can be restored. The disassembly and assembly are convenient and easy to operate.

[0057] Moreover, when the wheel limiter is installed on the skateboard, the wheel 300 of the skateboard is located in the wheel placement space, the board surface of the main side plate 1 is attached to the side surface of the wheel 300, the two first limiting strips 2 are attached to the outer circumferential surface of the wheel 300, and the axle 200 is stuck in the installation groove 11, so that the wheel 300 and the axle 200 are respectively restricted in a relatively limited space. The existence of the main side plate 1 and the first limiting strip 2 prevents the wheel 300 from contacting the ground without obstacles, restricts the free rotation of the wheel 300, and can reduce the possibility of the board body 100 of the skateboard rotating around the axle 200, preventing beginners from losing balance and falling when standing on the board body, which is also helpful for learning skateboarding skills, improving the overall stability of the skateboard, and increasing the safety of skateboarding practice. At the same time, when the skateboard with the wheel limiter is placed on the ground, the skateboard will not slide by itself, which is convenient for the fixed placement of the skateboard.

[0058] The main side plate 1 can be designed into various shapes as required. The main side plate 1 of this embodiment is a flat plate with a designed contour. The extension line of the first limiting strip 2 in the length direction intersects with the plane where the main side plate 1 is located.

[0059] Specifically, the bottom surface of the main side plate 1 is a convex curved surface protruding downward. In this way, when in use, the main side plate 1 is perpendicular to the ground, the bottom surface of the main side plate 1 contacts the ground, and the wheel 300 is not completely fixed. The wheel 300 can rotate within the curvature range of the bottom surface of the main side plate 1 to a certain extent, which is conducive to beginners to adapt to the shaking of the skateboard, and does not cause the beginners to fall due to excessive rotation of the wheel 300, which is conducive to skateboard learning.

[0060] In this embodiment, the lower part of the main side plate 1 is an arched plate, the bottom surface of the main side plate 1 is a convex arc surface protruding downward, and the extension direction of the generatrix of the bottom surface of the main side plate 1 is parallel to the thickness direction of the main side plate 1. The convex arc surface of the main side plate 1 is matched with the outer circumferential surface of the wheel 300, and when in use, the wheel 300 has a larger rotation range, and the experience is better.

[0061] Furthermore, the lower part of the main side plate 1 can be a major arc arch plate, a minor arc arch plate, or a semicircular plate. The bottom surface of the main side plate 1 is a partial arc surface or a full arc surface of the arch plate.

[0062] In addition, there are many design methods for the structure of the upper portion of the main side plate 1, and this embodiment discloses one of them.

[0063] For details, see again Figure 2 The upper part of the main side plate 1 includes two ear plates 13, the ear plates 13 are inverted V-shaped plates, the ear plates 13 are connected to the lower part of the main side plate 1, and a V-shaped guide groove 12 is provided between the two ear plates 13, and the lower end of the guide groove 12 is connected to the upper end of the installation groove 11. The axle 200 of the skateboard moves downward along the guide groove 12 and can enter the installation groove 11, which is convenient for the installation of the axle 200.

[0064] Moreover, the upper and lower parts of the main side plate 1 together form the shape of a rabbit head, which has a lovely appearance.

[0065] In this embodiment, the length extension direction of the mounting groove 11 is parallel to the thickness direction of the main side plate 1, that is, the mounting groove 11 crosses the main side plate 1, and the mounting groove 11 is cut off by a section perpendicular to the length extension direction of the mounting groove 11. The cross-sectional shape of the mounting groove 11 is an oval or circular shape with an open upper end. The shape of the mounting groove 11 is adapted to the shape of the axle 200, which is convenient for installation.

[0066] Preferably, the main side plate 1 is made of soft plastic, rubber or silicone, etc., wherein the soft plastic can be soft PVC. In this way, the main side plate 1 has a certain flexibility and rigidity, and the axle 200 can enter the installation groove 11 without the aid of tools, thereby forming a support for the entire skateboard.

[0067] Furthermore, the wheel limiter is integrally formed, and the material of the wheel limiter is soft plastic, rubber or silicone, etc. In this way, the wheel limiter is lightweight, portable, and temporary, and can be installed without the aid of tools, so that when the skateboarder uses the skateboard, the wheel 300 is kept in contact with the ground, and the added mass of the wheel limiter is not significant relative to the mass of the skateboard, and the position of the wheel limiter is near the center of gravity of the skateboard, so that the dynamic rotation properties of the skateboard with the wheel limiter do not change significantly, and the weight and overall feel of the skateboard are not affected, which helps to practice skills while protecting beginners.

[0068] Moreover, there are many design methods for the connection position between the first restriction strip 2 and the main side panel 1. For example, the first restriction strip 2 is connected to one of the panels of the main side panel 1, or the first restriction strip 2 is connected to the side of the main side panel 1.

[0069] In this embodiment, see again Figure 1, the first limiting strip 2 is connected to the side surface of the lower part of the main side panel 1, and the two first limiting strips 2 are respectively located on both sides of the bottom surface of the main side panel 1, and the first limiting strip 2 protrudes from the side surface of the main side panel 1, that is, the first limiting strip 2 is located outside the board surface range of the main side panel 1, and the lowest point of the first limiting strip 2 is flush with the lowest point of the main side panel 1. The board surface of the main side panel 1 refers to the two surfaces of the main side panel 1 in the non-thickness direction, and the side surface, bottom surface and upper end surface of the main side panel 1 are all surfaces of the main side panel 1 in the thickness direction.

[0070] Furthermore, the plate surface of the main side plate 1 is perpendicular to the length direction of the first limiting strip 2, and the length of the first limiting strip 2 is greater than the thickness of the main side plate 1. One end surface of the first limiting strip 2 is flush with one of the plate surfaces of the main side plate 1, and the other end surface of the first limiting strip 2 protrudes from the other plate surface of the main side plate 1, that is, the other end of the first limiting strip 2 extends away from the main side plate 1, and the length of the first limiting strip 2 protruding from the other plate surface of the main side plate 1 is greater than, less than or equal to the axial width of the wheel 300. When in use, the wheel 300 is located on the two first limiting strips 2, and the first limiting strips 2 provide resistance to the rotation of the wheel 300.

[0071] Furthermore, there are many design methods for the shape of the first restriction strip 2, and this embodiment discloses one of them.

[0072] Specifically, see Figure 1 The first limiting strip 2 is provided with a first side surface 21 and a second side surface 22 .

[0073] The first side surfaces 21 of the two first limiting strips 2 are arranged opposite to each other, and the wheel space is formed between the main side plate 1 and the two first side surfaces 21, and the first side surfaces 21 are concave curved surfaces. The arrangement of the first side surfaces 21 can increase the contact area between the first limiting strips 2 and the wheels 300, increase the friction resistance of the first limiting strips 2 to the wheels 300, and achieve a better effect of limiting the rotation of the wheels 300.

[0074] In this embodiment, the first side surface 21 is an inwardly concave arc surface, and the extension direction of the generatrix of the first side surface 21 is parallel to the length direction of the first restriction strip 2. The inwardly concave arc surface of the first side surface 21 is adapted to the shape of the outer circumferential surface of the wheel 300, so as to further increase the contact area between the first side surface 21 and the wheel 300, and enhance the braking effect of the first restriction strip 2 on the wheel 300.

[0075] Moreover, the second side surface 22 is an outward convex curved surface, the second side surface 22 is connected to the first side surface 21, and the second side surface 22 and the first side surface 21 together constitute the outer peripheral surface of the first limiting strip 2. The outer peripheral surface of the first limiting strip 2 here refers to a surface that is not perpendicular to the length direction of the first limiting strip 2, and the end surfaces of the first limiting strip 2 refer to two surfaces that are perpendicular to the length direction of the first limiting strip 2.

[0076] Furthermore, the second side surface 22 is an outwardly convex arc surface, and the extension direction of the generatrix of the second side surface 22 is parallel to the length direction of the first limiting strip 2 .

[0077] Thus, when in use, the second side surface 22 of the first limiting strip 2 and the bottom surface of the main side plate 1 are in contact with the ground, forming a limited movable space for the wheels 300 within an arc range, which will not cause the skateboard to tip over sideways or forward and backward.

[0078] Moreover, when viewed along the length direction of the first restriction strip 2, the first restriction strip 2 looks like a panda's ear, and when combined with the lower portion of the main side plate 1, it forms the shape of an inverted panda's head, which is very beautiful. Example

[0079] See also Figure 4-6 , a wheel limiter disclosed in this embodiment is the same as that in embodiment 1 except that the shape of the first limiting strip 2 is different, while other structures are the same.

[0080] This embodiment discloses another design method of the shape of the first restriction strip 2, specifically:

[0081] See also Figure 4 and 5 The first limiting strip 2 is provided with a first side surface 21 , a third side surface 23 and a fourth side surface 24 .

[0082] The first side surface 21 has the same structure as the first side surface 21 in Embodiment 1. The third side surface 23, the fourth side surface 24 and the first side surface 21 are connected to each other in this way, and the third side surface 23, the fourth side surface 24 and the first side surface 21 together constitute the outer peripheral surface of the first limiting strip 2. The third side surface 23 is a plane, an outer convex surface or an inner concave surface, and the fourth side surface 24 is a plane, an outer convex surface or an inner concave surface.

[0083] In this embodiment, the third side surface 23 and the fourth side surface 24 are both planes, and the first side surface 21 , the third side surface 23 and the fourth side surface 24 are connected to each other in a smooth transition.

[0084] In this way, when viewed along the length direction of the first restriction strip 2, the first restriction strip 2 looks like a cat's ear, and when combined with the lower portion of the main side plate 1, it forms a shape of an inverted cat's head, which is lovely and beautiful. Example

[0085] See also Figure 7 The wheel limiter disclosed in this embodiment is the same as that in Embodiment 1 and Embodiment 2 except that the structure of the upper portion of the main side plate 1 is different, while the other structures are the same.

[0086] This embodiment discloses another design method of the upper structure of the main side plate 1, specifically:

[0087] There is no ear plate 13 on the upper part of the main side plate 1 , the upper end surface of the main side plate 1 is a plane, the mounting groove 11 is opened on the upper part of the main side plate 1 , and the opening of the mounting groove 11 is arranged on the upper end surface of the mounting groove 11 .

[0088] In this way, the height of the main side plate 1 can be lowered, the space occupied by the wheel limiter can be reduced, and the storage and carrying can be facilitated. The weight of the wheel limiter can also be reduced, and the influence of the weight of the wheel limiter on skateboarding practice can be reduced. Example

[0089] See also Figure 8 The wheel limiter disclosed in this embodiment is based on any one of the embodiments 1-3, and some structures are added. The added structures are as follows:

[0090] A second limiting strip 6 is disposed on the upper portion of the main side plate 1 , and the wheel space is formed between the main side plate 1 , the first limiting strip 2 and the second limiting strip 6 .

[0091] The shape of the second restriction strip 6 is the same as or different from the shape of the first restriction strip 2 .

[0092] In this embodiment, two second limiting strips 6 are provided, and the two second limiting strips 6 are respectively connected to the two side surfaces of the upper part of the main side plate 1, and the second limiting strips 6 protrude from the side surfaces of the main side plate 1, and the second limiting strips 6 and the first limiting strips 2 are parallel to each other in the length direction.

[0093] When in use, the upper part of the outer circumferential surface of the wheel 300 abuts against the second limiting strip 6, and the lower part of the outer circumferential surface of the wheel 300 abuts against the first side surface 21 of the first limiting strip 2. The first limiting strip 2 and the second limiting strip 6 form a multi-sided limit for the wheel 300, further enhancing the effect of limiting the rotation of the wheel 300. Example

[0094] See also Figure 9-13 The wheel limiter disclosed in this embodiment is based on any one of the embodiments 1-4, and some structures are added. The added structures are as follows:

[0095] In the first case, see Figure 9-12 The upper end of the first restriction strip 2 is provided with a wheel-wrapped curved plate 3, the wheel-wrapped curved plate 3 and the first restriction strip 2 are connected, the wheel-wrapped curved plate 3 is an arc plate, and the extension direction of the generatrix of the wheel-wrapped curved plate 3 is parallel to the length direction of the first restriction strip 2. Figure 9-11 , the wheel-wrapped curved plate 3 can be connected to the main side plate 1; or, see Fig.12 , the wheel-wrapped curved plate 3 may also be disconnected from the main side plate 1, that is, there is a gap between the wheel-wrapped curved plate 3 and the main side plate 1;

[0096] In the second case, see Fig.13The main side panel 1 is provided with a wheel-wrapped curved plate 3, and the wheel-wrapped curved plate 3 is located above the first limiting strip 2, that is, the wheel-wrapped curved plate 3 is connected to the main side panel 1 and is not connected to the first limiting strip 2. There is a gap between the wheel-wrapped curved plate 3 and the first limiting strip 2. The wheel-wrapped curved plate 3 is an arc plate, and the extension direction of the generatrix of the wheel-wrapped curved plate 3 is parallel to the length direction of the first limiting strip 2.

[0097] In this embodiment, the wheel-enclosing curved plate 3 and the first side surface 21 are coaxial, and the inner side surface of the wheel-enclosing curved plate 3 and the first side surface 21 have the same arc radius.

[0098] Moreover, the generatrix length of the wheel-enclosing curved plate 3 may be greater than, less than or equal to the length of the first limiting strip 2 .

[0099] Specifically, the wheel-enclosing curved plate 3 and the first limiting strip 2 together form a semi-enclosed limiting space for the wheel 300. The design of the wheel-enclosing curved plate 3 greatly increases the contact area between the wheel limiter and the outer circumferential surface of the wheel 300. When the wheel 300 tends to rotate, the wheel-enclosing curved plate 3 and the first limiting strip 2 together generate friction resistance to the wheel 300 to prevent the wheel 300 from rotating. Example

[0100] See also Fig.14 The wheel limiter disclosed in this embodiment is based on any one of the embodiments 1 to 5, and some structures are added. The added structures are as follows:

[0101] A bridge plate 4 is provided between the two first limiting strips 2. Adding a bridge plate 4 between the two first limiting strips 2 as a reinforcement member enhances the supporting strength of the first limiting strips 2 and also prevents failure of the fixing device due to damage to a single first limiting strip 2.

[0102] Specifically, the bridge plate 4 is an arc plate, the bridge plate 4 and the first side surface 21 are coaxial, and the inner side surface of the bridge plate 4 has the same arc radius as the first side surface 21. The bridge plate 4 may be provided with holes or grooves.

[0103] Furthermore, the bridge plate 4 is connected to the main side plate 1. The width of the bridge plate 4 is the same as the length of the first limit strip 2 beyond the main side plate 1, and the bridge plate 4 fills the gap between the two first limit strips 2. When in use, the bottom of the wheel 300 is located on the bridge plate 4, and the wheel 300 does not contact the ground, so that the wheel 300 is locked in the wheel limiter and cannot rotate, which improves the overall stability of the skateboard. The skateboarder only needs to practice within the arc range of the bridge plate 4, which enhances safety.

[0104] Alternatively, there is a gap between the bridge plate 4 and the main side plate 1; if the gap is smaller than the width of the wheel 300, when in use, the bottom part of the wheel 300 is located on the bridge plate 4, and the bridge plate 4 can increase the friction resistance of the wheel limiter to the wheel 300; if the gap is equal to or greater than the width of the wheel 300, when in use, the bottom of the wheel 300 is in the gap, and the bridge plate 4 can abut against the side of the wheel 300 to enhance the friction resistance, wherein the bottom of the wheel 300 contacts the ground in the gap, which also enhances the experience. Example

[0105] See also Fig.15 The wheel limiter disclosed in this embodiment is based on any one of the embodiments 1-6, and some structures are added. The added structures are as follows:

[0106] The wheel limiter further comprises an auxiliary side plate 5, wherein the first limiting strip 2 is arranged between the main side plate 1 and the auxiliary side plate 5, and the other end of the first limiting strip 2 is connected to the lower part of the auxiliary side plate 5. The auxiliary side plate 5 and the main side plate 1 have the same or different shapes.

[0107] Specifically, the auxiliary side plate 5 can strengthen the strength of the wheel limiter, especially the strength of the first limiting strip 2. When in use, the auxiliary side plate 5 is located on the outside of the wheel 300, and the main side plate 1 is located on the inside of the wheel 300. The wheel 300 is placed on the first limiting strip 2 between the main side plate 1 and the auxiliary side plate 5.

[0108] Furthermore, in order to strengthen the connection between the wheel limiter and the skateboard, a limiting protrusion 51 is provided on the inner side of the auxiliary side plate 5, and a limiting groove 52 is provided on the limiting protrusion 51. The limiting protrusion 51 is located in the wheel placement space, and the limiting groove 52 is connected to the wheel placement space. The limiting protrusion 51 is suitable for a skateboard with a depression or a nut on the outside of the wheel 300. The limiting protrusion 51 can be stuck in the depression on the outside of the wheel 300, or the nut on the outside of the wheel 300 can be stuck in the limiting groove 52, thereby enhancing the limitation of the wheel. Example

[0109] See also Figure 16-17 The present embodiment discloses a wheel limiting device, comprising a connecting rod 20 and two wheel limiters 10 as described in any of the above embodiments, wherein the two ends of the connecting rod 20 are respectively connected to the main side plates 1 of the two wheel limiters 10, and the connecting rod 20 does not interfere with the wheel placement space.

[0110] Furthermore, the length direction of the connecting rod 20 is parallel to the length extension direction of the mounting groove 11, and the length direction of the connecting rod 20 is perpendicular to the plate surface of the main side plate 1. The connecting rod 20 is provided with a groove 201 in the length direction, and the groove 201 is connected to the mounting groove 11, and the bottom of the groove 201 is flush with the bottom of the mounting groove 11. The groove 201 is used to place the axle 200 to prevent the axle 200 from being suspended in the air.

[0111] Specifically, the wheel limiter device uses a connecting rod 20 to connect two wheel limiters 10. The two wheel limiters 10 are respectively installed at both ends of an axle 200 to limit the two wheels 300 of the same axle 200. The connecting rod 20 enhances the center positioning and bearing strength between the two wheel limiters 10, further prevents the rotation of the axle 200 and the wheel 300, improves the stability of the skateboard, and prevents beginners from falling.

[0112] In summary, skateboarders can use wheel limiters or wheel limit devices of different sizes or structures to restrict the wheel 300 to different degrees, so that they can practice at different rotation degrees of the wheel 300 to adapt to skateboarders of different technical levels. It is highly versatile and practical.
