Description

Technical Field

[0001] This invention relates to a bicycle stand for use during bicycle riding practice. Background Technology

[0002] Previously, it was known that there were various types of bicycle stands that could clamp and support the wheels of bicycles without stands from both sides, allowing them to stop on their own.

[0003] For example, Patent Document 1 discloses a bicycle stand, which is a movable bicycle stand that supports a bicycle wheel. The bicycle stand is characterized by comprising: a pair of left and right support members that clamp and support the wheel from both sides; leg members connected to the lower ends of the support members; and a hinge member connected to the middle portion of the support members in the vertical direction. Each support member has a column member located at the front and rear sides, and a crossbeam member connecting the upper ends of the column members. The upper ends of the leg members are rotatably connected to each other in a left-right split manner. The lower ends of the column members of the support members are connected to the middle portion of the leg members. The hinge member has... A pair of hinge plates on the front side and a pair of hinge plates on the rear side are detachably connected between the middle of the left and right column members on the front side of the support member, and a pair of hinge plates on the rear side are detachably connected between the middle of the left and right column members on the rear side of the support member. In each pair of front and rear hinge plates, one end of the hinge plate is axially supported at the middle of the column member, and the other end is axially supported by a common shaft member. This configuration is used to mount the wheel and bear its load. When the wheel is mounted on the hinge members on the front and rear sides, under the load of the wheel, the hinge members and the support member close together by bringing the crossbeam members closer to each other, thus clamping and supporting the wheel from the left and right.

[0004] According to Patent Document 1, a movable bicycle stand can be provided that is easy to operate and can stably support the bicycle by simply mounting the wheel, clamping the tire of the wheel, and suppressing the lateral movement of the wheel.

[0007] Patent Document 1: Japanese Patent Application Publication No. 2019-107952 Summary of the Invention

[0008] The problem the invention aims to solve

[0009] However, in the bicycle stand of Patent Document 1, although it is possible to make the bicycle self-supporting and stop, it is not conceivable to ride a bicycle in the self-supporting and stopped state.

[0010] On the other hand, children learning to ride a bicycle for the first time need to learn both the actions of balancing and pedaling, but it is difficult to learn both simultaneously. While balancing can be practiced using a balance bike without pedals, there has historically been no device for practicing pedaling independently. This invention addresses this problem by providing a bicycle stand that allows for independent pedaling practice during bicycle riding exercises, separate from the balancing action.

[0011] Solution for solving the problem

[0012] To achieve the above objectives, the present invention provides a bicycle bracket comprising: a support member having at least a pair of sidewall portions; and a pair of axle support members having an axle support portion for supporting the end of an axle of a bicycle wheel, and a support member engagement portion engaging with the upper edge of the sidewall portions. Furthermore, the support member can be used as a portion of a package for bundling the bicycle. Alternatively, the bicycle bracket may also include a nut member having an outer diameter larger than the inner diameter of the axle support portion, and threadedly engaging with the end of the axle.

[0013] Alternatively, the shaft support member may have a hook-shaped bicycle engaging portion that engages with the left and right sides of a portion of the bicycle. Alternatively, the distance between the upper edges of the pair of sidewall portions may be narrower than the distance between the lower ends.

[0014] Alternatively, the bicycle bracket may have ribs formed at the engaging portion to prevent misalignment between the sidewall portion and the axle support member. Alternatively, a groove may be formed for insertion of the upper edge, extending along the length of the axle support member and inclined in the width direction. Alternatively, the bicycle bracket may also include a fixing member that engages with the support member to fix the relative positions of the pair of sidewall portions. Alternatively, the fixing member may be connected to the pair of axle support members. Alternatively, the support member may be a corrugated cardboard member. Furthermore, the support member may have a notch at the upper edge of the sidewall portion for engagement with the axle support portion. Alternatively, the bicycle bracket may include a reinforcing member embedded in the bottom of the support member to prevent deformation of the support member; this reinforcing member, like the support member, may be a corrugated cardboard member. The reinforcing member is rectangular before use; during use, its two ends in the extending direction are raised in a prismatic shape extending along the side ends, and the two ends are erected and assembled. Alternatively, preferably, the reinforcing member is assembled by inserting a trapezoidal claw member, which is cut into the bottom surface, into a square hole provided in the prism-shaped member. Preferably, the reinforcing member has a second square hole in the prism-shaped member, and the supporting member has a second trapezoidal claw portion, which is cut into the second square hole to form an engaging portion.

[0015] Alternatively, the support member can be constructed by combining a base member with a front member and a rear member. The base member is formed by bending the right side wall and the left side wall parallel to each other across the bottom. The front member and the rear member are orthogonal to the right side wall and the left side wall.

[0016] The effects of the invention

[0017] According to the present invention, a bicycle stand is provided that allows for independent pedaling practice during bicycle riding practice, separate from the operation of achieving balance. Attached Figure Description

[0048] Hereinafter, preferred embodiments for carrying out the present invention will be described with reference to the accompanying drawings. Furthermore, the embodiments described below represent an example of a representative embodiment of the present invention and are not intended to limit the scope of the invention; various combinations, modifications, and alterations are possible within the scope of its spirit.

[0049] <First Embodiment>

[0050] First, refer to Figure 1 and Figure 2 An example of the structure of a bicycle bracket according to the first embodiment of the present invention will be described. Figure 1 This is a schematic diagram illustrating a structural example of the bicycle support 100 according to this embodiment. Figure 2 This is a vertical sectional view through the center of the tire, showing a structural example of a bicycle support 100.

[0051] like Figure 1 and Figure 2 As shown, as an example, the bicycle 101 of this embodiment includes a rear wheel 102, a rear wheel axle 103 located at the center of the rear wheel 102, and a frame 104 extending along the left and right sides of the rear wheel 102 and supporting the rear wheel axle 103 from the left and right sides. In addition, the bicycle 101 includes a seat, pedals, a chain cover, and a chain.

[0052] In addition, the bicycle bracket 100 of this embodiment includes a support member 105, a pair of axle support members 106R and axle support members 106L, and a nut member 107 that is threadedly connected to the left and right ends of the rear wheel axle 103.

[0053] As an example, the support member 105 is formed as a cuboid shape with the longitudinal direction of the bicycle 101 as the longitudinal direction, and the upper surface is open. The support member 105 has at least a pair of side wall portions 111 opposite to the left and right sides of the bicycle 101, an upper edge portion 112 of the side wall portions 111, a front surface portion 116, a rear surface portion 117, and a bottom portion 118, and has a notch portion 113 formed in the front surface portion 116 corresponding to the rear wheel 102.

[0054] The axle support member 106R and axle support member 106L each have: an axle support portion 114 that supports the end of the rear wheel axle 103 of the rear wheel 102, which serves as the wheel of the bicycle 101; and a support member engaging portion 119 that engages with the upper edge portion 112 of the side wall portion 111.

[0055] like Figure 2 As shown, the axle support member 106R and axle support member 106L also have a hook-shaped bicycle engaging portion 115, which engages with the left and right sides of the frame 104, which is part of the bicycle 101.

[0056] The nut component 107 has an outer diameter larger than the inner diameter of the shaft support portion 114 of the shaft support component 106R and the shaft support component 106L, and is threaded onto the left and right ends of the rear wheel axle 103. Using this nut component 107 and the bicycle engaging portion 115, even if the support component 105 deforms, the shaft support components 106R and 106L can be prevented from detaching from the ends of the rear wheel axle 103.

[0057] The support member 105 of the bicycle bracket 100 is a corrugated cardboard member, formed from a portion of the corrugated cardboard used as the packaging body for bundling the bicycle 101. Therefore, the lateral width of the support member 105 is greater than the width of the bicycle 101. Furthermore, the front surface portion 116 is formed by bending the side or bottom surface of the corrugated cardboard. By placing the bicycle 101 under the longitudinal grain of the corrugated cardboard, the support member 105, as a corrugated cardboard member, ensures strength. Additionally, regarding the distance between the pair of sidewall portions 111 of the support member 105, the upper edges 112 are the same width as the lower ends.

[0058] According to the bicycle stand 100 of this embodiment, when practicing riding the bicycle 101, the pedaling action can be practiced independently of the balance-gaining action. Therefore, children and others who are not familiar with the pedaling action can practice the pedaling action independently of the balance-gaining action, and can pedal smoothly and ride the bicycle 101 in actual use.

[0059] Furthermore, according to the bicycle bracket 100, by utilizing the corrugated cardboard used to bundle the bicycle 101, the number of additional components prepared separately relative to the bicycle 101 is minimized, thereby reducing the environmental burden and cutting costs.

[0060] <Modifications of the First Embodiment>

[0061] Next, refer to Figure 3 and Figure 4 This section describes a variation of the bicycle bracket 100 according to this embodiment. Figure 3 This is a schematic diagram showing a structural example of a bicycle bracket 120, which is a variation of the bicycle bracket 100. Figure 4 This is a vertical sectional view showing the structural example of the bicycle bracket 120 in this modified example.

[0062] like Figure 3 and Figure 4 As shown, the bicycle bracket 120 of this modified example includes: a support member 121; a pair of axle support members 122R and axle support members 122L; and a nut member 123, which is threadedly engaged with the left and right ends of the rear wheel axle 103.

[0063] As an example, the support member 121 is formed into a generally cuboid shape with the longitudinal direction of the bicycle 101 as the longitudinal direction, and the upper surface is open. The support member 121 has at least a pair of side wall portions 131 opposite to the left and right sides of the bicycle 101, an upper edge portion 132 of the side wall portions 131, and a notch portion 133 formed on the side in front of the rear wheel 102.

[0064] The axle support member 122R and axle support member 122L each have: an axle support portion 134 that supports the end of the rear wheel axle 103 of the rear wheel 102, which serves as the wheel of the bicycle 101; and a support member engaging portion that engages with the upper edge portion 132 of the side wall portion 131.

[0065] A pair of sidewall portions 131 have inclined surfaces that slope toward the shaft support members 122R and 122L, which engage with each other's upper edges 132. Thus, the upper edges 132 are narrower than their lower ends are at each other in terms of their mutual distance. Furthermore, they are not inclined at the engagement position of the shaft support members 122R and 122L, but rather form mutually parallel planes.

[0066] like Figure 4 As shown, the axle support members 122R and 122L also have hook-shaped bicycle engaging portions 135, which engage with the left and right sides of the frame 104, which is part of the bicycle 101.

[0067] The nut component 123 has an outer diameter larger than the inner diameter of the shaft support portion 134 of the shaft support component 122R and the shaft support component 122L, and is threaded onto the left and right ends of the rear wheel axle 103. Using this nut component 123 and the bicycle engaging portion 135, even if the support component 121 deforms, the shaft support components 122R and 122L can be prevented from detaching from the ends of the rear wheel axle 103.

[0068] The bicycle stand 120 of this modified example, similar to the bicycle stand 100 of this embodiment, allows for independent pedaling practice during bicycle riding practice, separate from the operation of achieving balance. Furthermore, it reduces environmental impact and lowers costs.

[0069] Furthermore, according to the bicycle bracket 120, since the distance between the pair of sidewall portions 131 is such that the upper edges 132 are narrower than the lower edges, it can suppress lateral swaying during riding practice and improve stability compared to the bicycle bracket 100. Additionally, compared to the bicycle bracket 100, the bicycle bracket 120 can reduce the thickness of the axle support members 122R and 122L in the bicycle width direction, thus reducing material usage.

[0070] <Second Implementation>

[0071] Next, refer to Figures 5 to 7 The structure of the bicycle bracket 200 according to the second embodiment is explained. Figure 5 This is a schematic diagram illustrating a structural example of the bicycle support 200 according to this embodiment. Figure 6 This is a vertical sectional view through the center of the tire, showing a structural example of a bicycle support 200. Figure 7 This is a schematic diagram illustrating a structural example of the shaft support member of this embodiment.

[0072] like Figure 5 and Figure 6 As shown, as an example, the bicycle 151 of this embodiment includes a rear wheel 102, a rear wheel axle 103 located at the center of the rear wheel 102, and a frame 104 extending along the left and right sides of the rear wheel 102 and supporting the rear wheel axle 103 from the left and right axles. In addition, the bicycle 151 includes a seat 152, pedals 153, a chain cover 154, and a chain.

[0073] The bicycle bracket 200 of this embodiment includes a support member 201, a pair of axle support members 202R and axle support members 202L, and nut members 203 that are threadedly connected to the left and right ends of the rear wheel axle 103.

[0074] As an example, the support member 201 is formed into a cuboid shape with the longitudinal direction of the bicycle 151 as the longitudinal direction, and the upper surface is open. The support member 201 has at least a pair of side wall portions 211 opposite to the left and right sides of the bicycle 151, an upper edge portion 212 of the side wall portions 211, and a notch portion 213 formed on the side in front of the rear wheel 102.

[0075] Axle support members 202R and 202L each have: an axle support portion 214 that supports the end of the rear wheel axle 103 of the rear wheel 102, which serves as the wheel of the bicycle 151; and a support member engaging portion that engages with the upper edge portion 212 of the side wall portion 211. Furthermore, axle support members 202R and 202L extend along the upper edge portion 212 toward the front of the bicycle 151 and extend to the surface where the notch portion 213 is formed.

[0076] The nut component 203 has an outer diameter larger than the inner diameter of the shaft support portion 214 of the shaft support component 202R and the shaft support component 202L, and is threaded to the left and right ends of the rear wheel axle 103.

[0077] like Figure 6As shown, a pair of sidewall portions 211 have inclined surfaces that slope toward the shaft support members 202R and 202L that engage with each other's upper edges 212. Thus, the upper edges 212 are narrower than their lower ends for the distance between the pair of sidewall portions 211.

[0078] like Figure 7 As shown, the shaft support member 202L has a groove 221 formed in the support member engagement portion that engages with the upper edge portion 212, for the upper edge portion 212 to be inserted. The groove 221 extends along the length direction of the shaft support member 202L and is formed to be inclined in the width direction of the shaft support member 202L. Vertical ribs are provided inside the groove 221 to prevent horizontal displacement and to achieve material reduction and strength assurance. The shaft support member 202R also has a groove similar to the groove 221.

[0079] The bicycle stand 200 according to this embodiment, like the bicycle stand 100 of the first embodiment, allows for independent pedaling practice during bicycle riding practice on the bicycle 151, separate from the operation of achieving balance. Furthermore, it reduces environmental impact and lowers costs. Additionally, the axle support members 202R and 202L extend along the upper edge 212 towards the front of the bicycle 151 and extend to the side where the notch 213 is formed, thereby preventing deformation of the support members 201 and enabling more stable pedaling practice.

[0080] <Third Implementation>

[0081] Next, refer to Figure 8 The structure of the bicycle bracket 300 according to the third embodiment is explained. Figure 8 This is a schematic diagram illustrating a structural example of the bicycle support 300 according to this embodiment.

[0082] like Figure 8 As shown, as an example, the bicycle 151 of this embodiment includes a rear wheel 102, a rear wheel axle 103 located at the center of the rear wheel 102, and a frame 104 protecting the left and right sides of the rear wheel 102. In addition, the bicycle 151 includes a seat 152, pedals 153, a chain cover 154, and a chain.

[0083] The bicycle bracket 300 of this embodiment includes a support member 301, a pair of axle support members 302R and axle support members 302L, and nut members 303 that are threadedly connected to the left and right ends of the rear wheel axle 103.

[0084] As an example, the support member 301 is formed as a cuboid shape with the longitudinal direction of the bicycle 151 as the longitudinal direction, and the upper surface is open. The support member 301 has at least a pair of side wall portions 311 opposite to the left and right sides of the bicycle 151, an upper edge portion 312 of the side wall portions 311, and a notch formed on the surface in front of the rear wheel 102.

[0085] The axle support member 302R and axle support member 302L each have: an axle support portion 314 that supports the end of the rear wheel axle 103 of the rear wheel 102, which serves as the wheel of the bicycle 151; and a support member engaging portion that engages with the upper edge portion 312 of the side wall portion 311.

[0086] The bicycle bracket 300 also includes a fixing member 315, which engages with a notch formed on the front side of the support member 301 and fixes the relative positions of a pair of sidewall portions 311.

[0087] The nut component 303 has an outer diameter larger than the inner diameter of the shaft support portion 314 of the shaft support component 302R and the shaft support component 302L, and is threaded to the left and right ends of the rear wheel axle 103.

[0088] A pair of sidewall portions 311 have inclined surfaces that are inclined toward the shaft support members 302R and 302L that engage with each other's upper edges 312. As a result, the upper edges 312 are narrower than their lower ends are for the distance between the pair of sidewall portions 311.

[0089] The bicycle stand 300 according to this embodiment, like the bicycle stand 100 of the first embodiment, allows for independent pedaling practice during bicycle riding practice (151) from the operation of achieving balance. Furthermore, it reduces environmental impact and lowers costs.

[0090] Furthermore, in the bicycle bracket 300, the distance between the two sidewall portions 311 is such that the upper edges 312 are narrower than the lower edges, and a fixing member 315 is provided. Therefore, compared to the bicycle bracket 100, it can suppress lateral swaying during riding practice and improve stability. In addition, the fixing member 315 can prevent deformation of the support member 301. Moreover, the triangles printed on the positions of the support member 301, the axle support member 302R and the axle support member 302L, and the fixing member 315 are used for accurate installation to prevent incorrect installation.

[0091] <Fourth Implementation>

[0092] Next, refer to Figure 9 The structure of the bicycle bracket 400 according to the fourth embodiment is explained. Figure 9 This is a schematic diagram illustrating a structural example of the bicycle support 400 according to this embodiment.

[0093] like Figure 9 As shown, as an example, the bicycle 151 of this embodiment includes a rear wheel 102, a rear wheel axle 103 located at the center of the rear wheel 102, and a frame 104 protecting the left and right sides of the rear wheel 102. In addition, the bicycle 151 includes a seat 152, pedals 153, and a chain cover 154.

[0094] The bicycle bracket 400 of this embodiment includes a support member 401, a pair of axle support members 402R and axle support members 402L, and a nut member 403 that is threadedly connected to the left and right ends of the rear wheel axle 103.

[0095] As an example, the support member 401 is formed into a cuboid shape with the longitudinal direction of the bicycle 151 as the longitudinal direction, and the upper surface is open. The support member 401 has at least a pair of side wall portions 411 opposite to the left and right sides of the bicycle 151, an upper edge portion 412 of the side wall portions 411, and a notch formed on the side in front of the rear wheel 102.

[0096] Axle support members 402R and 402L each have: an axle support portion 414 that supports the end of the rear wheel axle 103 of the rear wheel 102, which serves as the wheel of the bicycle 151; and a support member engaging portion that engages with the upper edge portion 412 of the side wall portion 411. Furthermore, axle support members 402R and 402L extend along the upper edge portion 412 toward the front of the bicycle 151 and extend to the side where the notch portion 413 is formed.

[0097] The bicycle bracket 400 also integrally includes a fixing member 415, which engages with a notch formed on the side of the front side of the support member 401 and fixes the relative positions of a pair of sidewall portions 411. In this embodiment, the fixing member 415 is connected to a pair of shaft support members 402R and shaft support members 402L.

[0098] The nut component 403 has an outer diameter larger than the inner diameter of the shaft support portion 414 of the shaft support component 402R and the shaft support component 402L, and is threaded to the left and right ends of the rear wheel axle 103.

[0099] A pair of sidewall portions 411 have inclined surfaces that are inclined toward shaft support members 402R and 402L that engage with each other's upper edges 412. As a result, the upper edges 412 are narrower than their lower ends for the distance between the pair of sidewall portions 411.

[0100] The bicycle stand 400 according to this embodiment, like the bicycle stand 100 of the first embodiment, allows for independent pedaling practice during bicycle riding practice on the bicycle 151, separate from the operation of achieving balance. Furthermore, it reduces environmental impact and lowers costs.

[0101] Furthermore, according to the bicycle bracket 400, the distance between the two sidewall portions 411 is such that the upper edges 412 are narrower than the lower edges, and a fixing member 415 is provided. Therefore, compared to the bicycle bracket 100, it can suppress lateral swaying during riding practice and improve stability. In addition, the fixing member 415 is integrally formed with a pair of axle support members 402R and 402L, thus further suppressing deformation of the support member 401.

[0102] <Fifth Implementation>

[0103] Next, refer to Figures 10 to 14 An example of the structure of a pair of shaft support members 502R and shaft support members 502L for a bicycle bracket in the fifth embodiment is described. Figure 10 This is a schematic diagram showing a structural example as viewed from the surface of the shaft support member 502R. Figure 11 This is a schematic diagram showing a structural example as viewed from the back of the shaft support member 502R. Figure 12 This is a schematic diagram showing a structural example as viewed from the surface of the shaft support member 502L. Figure 13 This is a schematic diagram showing a structural example viewed from the back of the shaft support member 502L. Figure 14 This is a schematic diagram showing an example of the installation of the shaft support member 502L.

[0104] like Figure 10 and Figure 11 As shown, as an example, the axle support member 502R has: an axle support portion 514 that supports the end of the rear wheel axle 103 of the rear wheel 102 of the bicycle 101, which is the same as in the first embodiment; and a support member engaging portion that engages with the upper edge portion 112 of the side wall portion 111. Additionally, the axle support member 502R has a hook-shaped bicycle engaging portion 515 that engages with the left and right sides of the frame 104, which is part of the bicycle 101.

[0105] Multiple ribs may also be formed in the bicycle engagement portion 515 of the axle support member 502R. These multiple ribs are used to prevent the side wall portion 111 from shifting between the axle support member 502R and to save material while increasing strength.

[0106] like Figure 12 and Figure 13As shown, the axle support member 502L, like the axle support member 502R, has an axle support portion 514 and a support member engaging portion. Additionally, the axle support member 502L has a hook-shaped bicycle engaging portion 515.

[0122] <Eighth Implementation>

[0123] Next, refer to Figures 24 to 26 The structure of the bicycle bracket 800 according to the eighth embodiment is explained. Figure 24 This is an unfolded view showing a structural example of a bicycle bracket according to the eighth embodiment of the present invention. Figure 25 It is its three-dimensional image. Figure 26 This is its top view.

[0124] The bicycle bracket 800 is constructed by mounting the aforementioned pair of axle support members 502R and 502L on the upper edge of the support member 810, thereby supporting the axle of the bicycle's rear wheel. Unlike other bicycle brackets, the support member 810 is not made of corrugated cardboard used for bicycle binding, but rather of separately prepared corrugated cardboard. Even in this case, since the various components described below are small enough, they can be bound simultaneously with the corrugated cardboard used for bicycle binding without the need for separate delivery. Of course, it can also be constructed by cutting out a portion of the corrugated cardboard used for bicycle binding.

[0125] The support members 810 are assembled in a grid shape when viewed from above, and are combined with mutually parallel front members 805 and rear members 806 orthogonally relative to the base member 804. The base member 804 includes a bottom 803 and mutually parallel right side wall 801 and left side wall 802. A pair of shaft support members 502R and 502L are mounted on the upper edges of the right side wall 801 and the left side wall 802.

[0126] like Figure 24 As shown, the base member 804 is constructed by bending a plate-shaped member in a valley-shaped manner to form a cross-section resembling the Japanese kana character コ, thus forming a right side wall 801, a left side wall 802, and a bottom 803. Furthermore, it has a pair of slits 841 and 842 that extend from the right side wall 801 through the bottom 803 to the left side wall 802, and the front member 805 and the rear member 806 engage with these slits 841 and 842.

[0127] The front member 805 and the rear member 806 have the same shape and are formed by bending a plate-like member in a mountain-shaped fold at the center line 870, creating an axisymmetric front part 871 and a rear part 872. Furthermore, a pair of axially symmetrical slits 873 and 874 passing through the center line 870 are provided. These slits 873 and 874 engage with the aforementioned slits 841 and 842 and with the right side wall 801 and the left side wall 802. Additionally, a notch 875 is provided in the center in the left-right direction to avoid contact with the bicycle tire, thereby preventing contact with the bicycle tire when the bicycle is mounted on the bicycle stand 800 and used for pedaling practice.

[0128] The bicycle stand 800 according to this embodiment, in addition to having the same effects as the bicycle stand 100 of the first embodiment, improves the strength of lateral sway relative to the bicycle by utilizing the folded-shape front member 805 and rear member 806, and further enhances stability during riding practice. Furthermore, it provides an effective and compact bicycle stand at a low cost when bicycle strapping materials are unavailable, and it can also be strapped together with bicycle strapping materials.

[0129] <Ninth Embodiment>

[0130] Next, refer to Figures 27 to 30 The structure of the bicycle bracket 900 according to the ninth embodiment is explained. Figure 27 This is a unfolded view showing a structural example of a bicycle bracket according to the ninth embodiment of the present invention. Figure 28 It is a 3D diagram showing its assembled state. Figure 29 It is a three-dimensional diagram showing its bottom surface. Figure 30 This is a side view showing the usage status.

[0131] The bicycle bracket 900 is constructed by mounting a pair of axle support members 902R and 902L, which have the same function as the aforementioned axle support members, on the upper edge of the support member 901, thereby supporting the axle of the bicycle's rear wheel. The support member 901 is constructed by cutting out a portion of the corrugated cardboard used as the bicycle's packaging material, including the lower corner.

[0132] The support member 901 is cut out with openings at the top and front, and notches 901a and 901b are provided on the upper edge of the left and right side walls for mounting a pair of shaft support members 902R and shaft support members 902L.

[0133] The support member 901 has vertical slits 901c and 901e on the front of its left side wall for engaging with the reinforcing member 903, and similarly, it has vertical slits 901d and 901f on the front of its right side wall for engaging with the reinforcing member 903. The reinforcing member 903 is V-shaped by a left-right extending fold line and has a pair of vertical slits 903a and 903b passing through this fold line. By engaging with the vertical slits 901c, 901e and 901d, 901f through these slits 903a and 903b, the reinforcing member 903 engages with the support member 901, thereby reducing the deformation of the support member 901 caused by the left-right swinging of the bicycle.

[0134] like Figure 29 As shown, a portion of the bottom surface of the support member 901, which is a corrugated cardboard bottom flap 901g, has a notch 901h cut through the dotted lines. The bottom flap 901g is flap-shaped, thus facilitating access to the inside of the box member. When riding a bicycle, it prevents collisions with the rear wheel; therefore, the flap is shaped to avoid the rear wheel. Figure 30 As shown, even when the bottom flap 901g is raised while riding a bicycle and using the bicycle stand 900, the blank portion 901i formed by the cut notch 901h will prevent the rear wheel from hitting the bottom flap 901g.

[0135] The bicycle bracket 900 according to this embodiment, in addition to having the same effects as the bicycle bracket 900 of the first embodiment, further improves the stability of riding practice by increasing the strength of the swaying relative to the left and right direction of the bicycle using the reinforcing member 903. Furthermore, by using bicycle packing material, an effective and compact bicycle bracket can be provided inexpensively, which also contributes to resource conservation.

[0136] Furthermore, the effects described in this specification are illustrative only and are not limiting; other effects are also possible. The raw materials for the shaft support components and support components can also be paper, wood, resin, metals such as iron, or ceramics.
