Bicycle wheel structure with integral rim-spoke formation

[0001] The present invention relates to a bicycle wheel structure having an integral rim-spoke formed therein, and more particularly, to a bicycle wheel structure having an integral rim-spoke formed therein, which forms a structure in which a tire is mounted through an inner wheel and spokes, and which can eliminate shaking that occurs between a rim and a spoke by connecting the inner wheel and the spokes while forming a joint extending in the vertical direction.

[0002] Typically, a bicycle wheel structure includes a rim in the shape of a ring, a tire attached along the outer surface of the rim, and spokes attached to the inner surface of the rim. Fig. 1 is a drawing showing a conventional bicycle wheel structure.

[0003] Referring to Fig. 1, a conventional bicycle wheel structure includes a rim (10) to which a tire is coupled, and a spoke (20) that is coupled to the inner surface of the rim (10) and supports the rim (10). The conventional bicycle wheel structure is manufactured by forming the rim (10) and the spoke (20) separately and then coupling them together.

[0004] Specifically, as shown in Fig. 1, the rim (10) and the spoke (20) are manufactured separately, and the bicycle wheel structure is manufactured by combining the rim (10) to the upper portion of the spoke (20).

[0005] However, the conventional bicycle wheel structure has the following problems. The conventional bicycle wheel structure is manufactured by manufacturing the rim (10) and the spoke (20) separately and joining the rim (10) to the upper portion of the spoke (20), so there is a problem of shaking occurring at the joining point of the rim (10) and the spoke (20).

[0006] Specifically, when the rim (10) is coupled to the upper portion of the spoke (20), there is a problem in that it is difficult to increase the area where the spoke (20) and the rim (10) are coupled because the width of the spoke (20) is limited.

[0007] As it is difficult to increase the area where the spoke (20) and the rim (10) are joined, the joining force at the point where the spoke (20) and the rim (10) are joined may be reduced, and accordingly, there is a problem in that shaking occurs at the joining point of the rim (10) and the spoke (20) due to driving of the bicycle.

[0041] The present invention relates to a bicycle wheel structure having an integral rim-spoke formed therein, and relates to a bicycle wheel structure having an integral rim-spoke formed therein, which forms a structure in which a tire is mounted through an inner wheel and spokes, and which can eliminate shaking that occurs between a rim and a spoke by connecting the inner wheel and the spokes while forming a joint extending in the vertical direction.

[0042] A bicycle wheel structure having an integral rim-spoke formed according to an embodiment of the present invention forms an integral rim-spoke through an inner wheel and spokes. The bicycle wheel structure having an integral rim-spoke formed according to an embodiment of the present invention can form one side of the rim structure through the inner wheel and the other side of the rim structure through the spokes.

[0043] A bicycle wheel structure comprising an integrated rim-spoke according to an embodiment of the present invention can be applied to a regular bicycle or an electric bicycle. Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

[0044] A bicycle wheel structure having an integrated rim-spoke according to an embodiment of the present invention includes an inner wheel (110) and spokes (150).

[0045] Referring to FIGS. 2 and 3, the inner wheel (110) may be a wheel mounted on a bicycle wheel structure, and the inner wheel (110) may be processed to form a structure that can support a tire while it is seated.

[0046] Referring to FIG. 4, the inner wheel (110) may include a first connecting portion (120), a first fixing portion (130), and a first support portion (140). In the description to follow, the configuration according to the embodiment of the present invention extending in the vertical direction and the left and right direction may be a direction in which the first fixing portion (130) extends based on the case where the first fixing portion (130) is positioned at the top of the bicycle wheel structure as shown in FIG. 4.

[0047] Although the bicycle wheel structure according to an embodiment of the present invention can rotate around a center, the following description will describe the configuration according to an embodiment of the present invention based on the case where the first mounting portion (130) is positioned at the top of the bicycle wheel structure as shown in FIG. 4.

[0048] Referring to Fig. 4, the first coupling portion (120) extends in a vertical direction. The first coupling portion (120) may extend in a vertical direction or a vertical direction, and the first coupling portion (120) may extend in a direction toward the center of the wheel structure.

[0049] Referring to Fig. 4, the first mounting portion (130) extends from the end of the first connecting portion (120) to form a space in which the tire is mounted. The first mounting portion (130) extends while being bent in the left and right directions from the end of the first connecting portion (120).

[0050] Specifically, the first fixing portion (130) can extend in the left-right direction or horizontal direction from the end of the first connecting portion (120), and as the first fixing portion (130) extends in the left-right direction or horizontal direction from the end of the first connecting portion (120), a space in which a tire can be fixed can be formed.

[0051] Referring to Fig. 4, the first support portion (140) extends vertically from the end of the first mounting portion (130). The first support portion (140) may extend vertically or vertically, and may support the side surface of the tire through the first support portion (140).

[0052] Specifically, when the tire is mounted on the first mounting portion (130), the first support portion (140) comes into contact with the side surface of the tire, thereby supporting the tire through the first support portion (140).

[0053] According to an embodiment of the present invention, the first support portion (140) may include a first pressing portion (141) that is bent inwardly of the first fixing portion (130). The first pressing portion (141) is bent while protruding inwardly from the outer direction of the first fixing portion (130) toward the inner direction of the first fixing portion (130).

[0054] When a tire is mounted on the first mounting portion (130), the tire must be prevented from coming off the first mounting portion (130). The first pressurizing portion (141) is provided for this purpose, and as the first pressurizing portion (141) is bent inwardly of the first mounting portion (130), the side surface of the tire can be pressed through the first pressurizing portion (141).

[0055] More specifically, as the first pressure member (141) is bent while protruding from the outer side of the first mounting portion (130) toward the inner side of the first mounting portion (130), the tire can be forcibly fitted into the first mounting portion (130), thereby preventing the tire from being detached from the first mounting portion (130).

[0056] According to an embodiment of the present invention, the first support portion (140) may include a first support portion (142) that is bent in the outer direction of the first mounting portion (130) from the first pressing portion (141).

[0057] The first support portion (142) extends from the end of the first pressurizing portion (141) toward the outside of the first fixing portion (130). A tire according to an embodiment of the present invention may have a width wider than the sum of the width of the first fixing portion (130) and the width of the second fixing portion (170) described later.

[0058] Therefore, when the tire is mounted on the first mounting portion (130), a portion of the tire may be forcibly fitted onto the first mounting portion (130), and a specific portion of the tire that is not mounted on the first mounting portion (130) protrudes outward from the first mounting portion (130).

[0059] The first support portion (142) can support a specific portion of the tire that is not seated on the first mounting portion (130). The first support portion (142) can support the lower portion of a specific portion of the tire that is not seated on the first mounting portion (130), and by providing the first support portion (142), the tire can be stably seated on the first mounting portion (130).

[0060] Referring to FIGS. 2 and 3, the spoke (150) may be a member that supports a wheel structure for a vehicle while being provided with spokes. According to an embodiment of the present invention, by processing a portion of the spoke (150), a structure capable of supporting and mounting a tire can be formed.

[0061] Referring to FIG. 4, the spoke (150) may include a second connecting portion (160), a second fixing portion (170), and a second supporting portion (180). In the description to follow, the configuration according to the embodiment of the present invention extending in the vertical direction and the left and right direction may be a direction in which the second fixing portion (170) extends based on the case where the second fixing portion (170) is positioned at the top of the bicycle wheel structure as shown in FIG. 4.

[0062] Although the bicycle wheel structure according to an embodiment of the present invention can rotate around a center, the following description will describe the configuration according to an embodiment of the present invention based on the case where the second fixing portion (170) is positioned at the top of the bicycle wheel structure as shown in FIG. 4.

[0063] Referring to Fig. 4, the second coupling portion (160) extends in the vertical direction. The second coupling portion (160) may extend in the vertical direction or the vertical direction, and the second coupling portion (160) may extend in a direction toward the center of the wheel structure.

[0064] According to an embodiment of the present invention, the second coupling portion (160) may be extended longer than the first coupling portion (120), and the second coupling portion (160) may be formed of a spoke extending toward the center of the spoke (150). The second coupling portion (160) may be formed by processing the spoke of the spoke (150), and the second coupling portion (160) may be coupled with the first coupling portion (120).

[0065] Referring to Fig. 4, the second fixing portion (170) extends from the end of the second connecting portion (160) and comes into contact with the tire. The second fixing portion (170) can extend while being bent from the end of the second connecting portion (160).

[0066] The second mounting portion (170) according to an embodiment of the present invention may extend in the left-right direction or horizontal direction like the first mounting portion (130). As the second mounting portion (170) extends in the left-right direction or horizontal direction like the first mounting portion (130), a space in which a tire can be mounted can be formed through the second mounting portion (170).

[0067] However, it is not limited thereto, and the second fixing portion (170) may extend diagonally and vertically from the second connecting portion (160). The second fixing portion (170) may form a space where the tire comes into contact with one side of the first fixing portion (130), and if the space where the tire comes into contact can be formed, the second fixing portion (170) may extend diagonally and vertically from the second connecting portion (160).

[0068] Referring to Fig. 4, the second support portion (180) extends vertically from the end of the second mounting portion (170). The second support portion (180) may extend vertically or vertically, and may support the side surface of the tire through the second support portion (180).

[0069] Specifically, when the tire is mounted on the second mounting portion (170), the second support portion (180) comes into contact with the side surface of the tire, thereby supporting the tire through the second support portion (180).

[0070] According to an embodiment of the present invention, the second support portion (180) may include a second pressing portion (181) that is bent inwardly of the second fixing portion (170). The second pressing portion (181) is bent while protruding inwardly from the outer direction of the second fixing portion (170) toward the inner direction of the second fixing portion (170).

[0071] When the tire comes into contact with the second mounting portion (170), the tire must be prevented from coming off the second mounting portion (170). The second pressurizing portion (181) is provided for this purpose, and as the second pressurizing portion (181) is bent in the inward direction of the second mounting portion (170), the side surface of the tire can be pressed through the second pressurizing portion (181).

[0072] More specifically, as the second pressure member (181) is bent while protruding from the outer side of the second mounting portion (170) toward the inner side of the second mounting portion (170), the tire can be forcibly fitted into the second mounting portion (170), thereby preventing the tire from being detached from the second mounting portion (170).

[0073] According to an embodiment of the present invention, the second support portion (180) may include a second support portion (182) that is bent in the outer direction of the second mounting portion (170) from the second pressing portion (181).

[0074] The second support portion (182) extends from the end of the second pressurizing portion (181) toward the outside of the second mounting portion (170). The tire according to an embodiment of the present invention may have a width wider than the sum of the widths of the first mounting portion (130) and the second mounting portion (170).

[0075] Therefore, when the tire is mounted on the second mounting portion (170), a portion of the tire may be forcibly fitted onto the second mounting portion (170), and a specific portion of the tire that is not mounted on the second mounting portion (170) protrudes outward from the second mounting portion (170).

[0076] The second support member (182) can support a specific portion of the tire that is not seated on the second mounting member (170). The second support member (182) can support the lower portion of a specific portion of the tire that is not seated on the second mounting member (170), and by providing the second support member (182), the tire can be stably seated on the second mounting member (170).

[0077] Referring to Fig. 4, the inner wheel (110) and the spoke (150) according to an embodiment of the present invention can be joined through the first joining portion (120) and the second joining portion (160). Specifically, when the first joining portion (120) and the second joining portion (160) are joined, a joining portion (121) extending in the vertical direction can be formed.

[0078] As described above, the first coupling portion (120) and the second coupling portion (160) can extend in the vertical direction or the vertical direction. When the first coupling portion (120) and the second coupling portion (160) are joined, the joint area of ​​the first coupling portion (120) and the second coupling portion (160) can be increased as the first coupling portion (120) and the second coupling portion (160) extend in the vertical direction or the vertical direction.

[0079] Specifically, when the first joining portion (120) and the second joining portion (160) are joined to form the joining portion (121) extending in the vertical direction, the length of the joining portion (121) can be formed longer as the first joining portion (120) and the second joining portion (160) extend in the vertical direction or vertical direction, thereby improving the joining force between the inner wheel (110) and the spoke (150).

[0080] In the past, when a bicycle wheel structure was manufactured in a form in which a rim (10) was joined to the upper portion of a spoke (20), there was a problem in that shaking occurred at the joining point of the rim (10) and the spoke (20). In addition, when the rim (10) was joined to the upper portion of the spoke (20), there was a problem in that it was difficult to increase the joining area of ​​the spoke (20) and the rim (10) because the width of the spoke (20) was limited.

[0081] However, the bicycle wheel structure formed with an integrated rim-spoke according to an embodiment of the present invention forms a structure in which a tire is mounted through the inner wheel (110) and the spoke (150), thereby eliminating shaking that occurs between the rim (10) and the spoke (20).

[0082] In addition, the bicycle wheel structure having an integrated rim-spoke according to an embodiment of the present invention can form the joint (121) through the first joint (120) and the second joint (160) extending in the vertical direction, thereby connecting the inner wheel (110) and the spoke (150). Through this, the connecting area of ​​the inner wheel (110) and the spoke (150) is increased, thereby making it possible to firmly connect the inner wheel (110) and the spoke (150).

[0083] In addition, the bicycle wheel structure having an integrated rim-spoke according to an embodiment of the present invention can form a free space (122) inside the inner wheel (110) and the spoke (150) by connecting the inner wheel (110) and the spoke (150) while forming the joint (121) extending in the vertical direction.

[0084] When a rim (10) is joined to the upper part of a spoke (20) as in a conventional bicycle wheel structure, the inner space of the wheel structure may become narrower as one lower side and the other lower side of the rim (10) must be supported through the spoke (20).

[0085] However, the bicycle wheel structure having an integrated rim-spoke according to an embodiment of the present invention is formed by joining the first connecting portion (120) of the inner wheel (110) and the second connecting portion (160) of the spoke (150) as shown in FIG. 4, and forming the first mounting portion (130) by bending the end of the first connecting portion (120) of the inner wheel (110) in the left-right direction, thereby forming a free space (122) at the bottom of the first mounting portion (130).

[0086] As the free space (122) is formed in the lower portion of the first mounting portion (130) in this way, the volume of the wheel structure can be reduced. In addition, other components necessary for driving the bicycle can be placed in the free space (122).

[0087] Referring to FIGS. 5 and 6, a bicycle wheel structure formed with an integrated rim-spoke according to an embodiment of the present invention may include a sub inner wheel (210) and a sub spoke (250).

[0088] The above-mentioned sub inner wheel (210) and the above-mentioned sub spoke (250) may be provided to form a wheel structure for a double-wheel bicycle. A structure in which one tire is mounted may be formed through the above-mentioned inner wheel (110) and the above-mentioned spoke (150), and a structure in which another tire is mounted may be formed through the above-mentioned sub inner wheel (210) and the above-mentioned sub spoke (250).

[0089] Referring to FIGS. 6 and 7, the lower part of the sub spoke (250) can be connected to the lower part of the spoke (150) through a bolt (190) and a nut (191), and as the lower part of the sub spoke (250) is connected to the lower part of the spoke (150), a wheel structure for a double-wheel bicycle can be formed.

[0090] The above sub inner wheel (210) and the above sub spoke (250) can form a structure in which a tire is mounted, and the method for forming a structure in which a tire is mounted through the above sub inner wheel (210) and the above sub spoke (250) can be the same as the method for forming a structure in which a tire is mounted through the above inner wheel (110) and the above spoke (150).

[0091] Referring to FIGS. 5 and 6, the sub inner wheel (210) may be a wheel mounted on a bicycle wheel structure, and the sub inner wheel (210) may be processed to form a structure that can support a tire while it is seated.

[0092] Referring to FIG. 7, the sub inner wheel (210) may include a third connecting portion (220), a third fixing portion (230), and a third support portion (240). In the description to follow, the configuration according to the embodiment of the present invention extending in the vertical direction and the left and right direction may be a direction in which the third fixing portion (230) extends based on the case where the third fixing portion (230) is positioned at the top of the bicycle wheel structure as shown in FIG. 7.

[0093] Although the bicycle wheel structure according to an embodiment of the present invention can rotate around a center, the following description will describe the configuration according to an embodiment of the present invention based on the case where the third fixing portion (230) is positioned at the top of the bicycle wheel structure as shown in FIG. 7.

[0094] Referring to Fig. 7, the third coupling portion (220) extends in the vertical direction. The third coupling portion (220) may extend in the vertical direction or the vertical direction, and the third coupling portion (220) may extend in a direction toward the center of the wheel structure.

[0095] Referring to Fig. 7, the third mounting portion (230) extends from the end of the third connecting portion (220) to form a space in which the tire is mounted. The third mounting portion (230) extends while being bent in the left and right directions from the end of the third connecting portion (220).

[0096] Specifically, the third fixing portion (230) can extend in the left-right direction or horizontal direction from the end of the third connecting portion (220), and as the third fixing portion (230) extends in the left-right direction or horizontal direction from the end of the third connecting portion (220), a space in which a tire can be fixed can be formed.

[0097] Referring to Fig. 7, the third support portion (240) extends vertically from the end of the third mounting portion (230). The third support portion (240) may extend vertically or vertically, and may support the side surface of the tire through the third support portion (240).

[0098] Specifically, when the tire is mounted on the third mounting portion (230), the third support portion (240) comes into contact with the side surface of the tire, thereby supporting the tire through the third support portion (240).
