Description

Bicycle shoe coupling device

[0001] The present invention relates to a bicycle shoe coupling device, and more particularly, to a bicycle shoe coupling device that enables a bicycle shoe and a pedal to be coupled and separated using magnetic force.

[0002]

[0003] Typically, bicycles are powered by pedaling force, but special bicycles such as mountain bikes or cycles use both pedaling force and traction force to power the bicycle.

[0004] However, if you simply place your shoes on the bicycle pedals and pedal, slippage occurs between the shoes and the pedals, preventing the rotational power of the rider's footwork from being sufficiently transmitted to the pedals.

[0005] Accordingly, cleats are used by professional cyclists to increase the bond between bicycle shoes and pedals.

[0006] However, in the case of conventional cleats, the structure is applied to make it difficult to separate the shoes and pedals when the bicycle needs to be stopped, so even people who are skilled at pedaling with cleats often have difficulty separating them, resulting in accidents where they fall. In addition, the structure for connecting the shoes and pedals is complex, making the manufacturing process complicated, and in most cases, only one side of the pedal can be used, so improvement is needed.

[0007]

[0008] The present invention is intended to solve the above-described problems, and more specifically, to provide a bicycle shoe coupling device that enables a bicycle shoe and a pedal to be easily coupled and separated using magnetic force, and that enables the pedal to be coupled to a bicycle shoe in both the upper and lower directions by a simplified structure.

[0050]

[0051] First, a shoe coupling device for a bicycle according to an embodiment of the present invention largely includes a pedal frame (100), a first coupling means (200), and a shoe coupling means (300).

[0052] First, the pedal frame (100) is rotatably connected to the crank arm of the bicycle.

[0053] Next, the first coupling means (200) includes at least one magnetic body, and at least one is provided on the pedal frame (100) so that a magnetic force is applied in both the upper and lower directions of the pedal frame (100).

[0054] Next, the shoe coupling means (300) is detachably provided on the lower part of the shoe, is provided so as to be coupled to the first coupling means (200) based on magnetic force, and may include a ferromagnetic material including metal.

[0056]

[0057] Hereinafter, the present invention will be described with reference to the attached drawings.

[0058] FIG. 1 is a side sectional view illustrating a shoe coupling device for a bicycle according to a first embodiment of the present invention, FIG. 2 is a side sectional view illustrating a shoe coupling device for a bicycle according to a second embodiment of the present invention, FIG. 3 is a side sectional view illustrating a shoe coupling device for a bicycle according to a third embodiment of the present invention, and FIG. 4 is a side sectional view illustrating a shoe coupling device for a bicycle according to a fourth embodiment of the present invention.

[0059] With reference to FIGS. 1 to 4, various embodiments of the first coupling means (200) will be examined in more detail. For reference, FIGS. 1 to 4 illustrate an example in which a pedal frame (100) is provided with a plurality of first coupling means (200).

[0060]

[0061] First, referring to FIG. 1, in the bicycle shoe coupling device according to the first embodiment of the present invention, the first coupling means (200) includes a mounting hole (210), a pair of stoppers (220), and a magnet (230).

[0062] Looking at it in more detail, first, the mounting hole (210) is formed by penetrating the pedal frame (100) vertically to form a space in which a magnet (230) is accommodated inside and can move up and down.

[0063] At this time, a pair of stoppers (220) are provided at both upper and lower ends of the mounting hole (210) to protrude inwardly from the mounting hole (210) so as to prevent the magnet (230) accommodated in the internal space of the mounting hole (210) from being separated to the outside, and also the range in which the magnet (230) moves can be limited by the stopper (220). For example, the stopper (220) may be configured to include at least one protrusion provided along the periphery of the mounting hole (210), or as another example, the stopper (220) may be configured to have a ring shape as illustrated in FIG. 1.

[0064] In addition, the magnet (230) is provided so as to be accommodated in the internal space of the mounting hole (210) so that the shoe coupling means (300) can be coupled with the pedal frame (100) by magnetic force, and is provided so as to be able to slide along the mounting hole (210), so that even if the pedal frame (100) is rotated and the upper and lower arrangement directions are switched, the magnet (230) is moved in a direction approaching the shoe coupling means (300) provided on the user's shoe located above the pedal frame (100), like the first coupling means (200) illustrated on the left side of the pedal frame (100) in FIG. 1, so that the magnet (230) and the shoe coupling means (300) are coupled by magnetic force, thereby providing a coupling force so that the pedal frame (100) and the shoe can be coupled.

[0065] Accordingly, the shoe coupling device for a bicycle according to the first embodiment of the present invention can directly transmit magnetic force and apply coupling force without an intervening means such as a cover between the magnet (230) of the first coupling means (200) and the shoe coupling means (300) by the ring-shaped stopper (220), thereby improving the coupling force between the shoe and the pedal frame (100), thereby preventing slipping of the shoe and providing the effect of enabling more stable use of the bicycle.

[0066] Meanwhile, the magnet (230) may further include an intermediate body part (231) positioned in the space between a pair of stoppers (220) in the internal space of the mounting hole (210), and magnetic protrusions (232) formed protrudingly at both ends of the intermediate body part (231) so as to be inserted through the ring-shaped stopper (220). In this case, as an example, as shown in FIG. 1, the magnetic protrusions (232) are formed protrudingly with the same size as the thickness of the stopper (220), so that the outer end of the magnetic protrusions (232) inserted through the stopper (220) while the magnet (230) is restricted from moving by the stopper (220) and the end of the stopper (220) facing the outside of the mounting hole (210) are positioned on the same plane, so that the end surface of the magnet (230) can be in direct contact with the shoe coupling means (300). It can be configured to further enhance the bonding force between the magnet (230) and the shoe coupling means (300). In addition, the intermediate body part (231) can be configured to have a cross-section of a size and shape corresponding to the cross-section of the mounting hole (210), so that the magnet (230) can move along the mounting hole (210) while the magnetic protrusion (232) is maintained aligned toward the upper and lower sides of the pedal frame (100).

[0067] Meanwhile, the stopper (220) may be formed integrally with the pedal frame (100) or, as shown in FIG. 1, may be provided as a ring-shaped member formed as a separate body from the pedal frame (100), and may be configured to be coupled to the mounting hole (210) by a screw fastening structure. In addition, the stopper (220) can be configured to be able to adjust the mounting position at which the stopper (220) is mounted on the mounting hole (210) by being rotated by the user through a screw-fastening structure, and in this case, when the shoe coupling means (300) and the magnet (230) are coupled by magnetic force through the mounting structure of the stopper (220), the magnet (230) moves along the mounting hole (210) and the movement is restricted by the stopper (220), thereby enabling adjustment of the distance between the shoe coupling means (300) and the end of the magnet (230). As a result, the end of the magnet (230) and the shoe coupling means (300) come into direct contact, or the distance between the end of the magnet (230) and the shoe coupling means (300) is varied, thereby allowing adjustment of the coupling force between the magnet (230) and the shoe coupling means (300).

[0068] Meanwhile, the first coupling means (200) may include one magnet (230) as shown in FIG. 1, or may further include a separate connecting body, although not shown in the drawing, so that magnets are provided at each of the upper and lower ends of the connecting body.

[0069]

[0070] Referring to FIG. 2, in the bicycle shoe coupling device according to the second embodiment of the present invention, the first coupling means (200) includes a mounting hole (210), a stopper (220), a magnet (230), and a movement restriction groove (290).

[0071] Looking at it in more detail, first, the mounting hole (210) is formed by penetrating the pedal frame (100) vertically to form a space in which a magnet (230) is accommodated inside and can move up and down.

[0072] In addition, the magnet (230) is provided so that the shoe coupling means (300) can be coupled to the pedal frame (100) by magnetic force, and is accommodated in the internal space of the mounting hole (210) and can slide along the mounting hole (210), so that even if the pedal frame (100) is rotated and the upper and lower arrangement directions are changed, the magnet (230) is moved in a direction approaching the shoe coupling means (300) provided on the user's shoe located above the pedal frame (100), like the first coupling means (200) illustrated on the left side of the pedal frame (100) in FIG. 2, so that the magnet (230) and the shoe coupling means (300) are coupled by magnetic force, and a coupling force is provided so that the pedal frame (100) and the shoe can be coupled.

[0073] In addition, a movement restriction groove (290) may be formed in the inner surface of the middle portion of the mounting hole (210), and the stopper (220) may be mounted in a fixed groove formed in the outer surface of the magnet (230) so that the outer end is fitted into the movement restriction groove (290) to prevent the magnet (230) from being separated from the mounting hole (210) to the outside. At this time, as an example, the stopper (220) may be configured to be made of a material that is elastic in itself, such as a snap ring, or as another example, as illustrated in FIG. 2, a separate elastic member (280) may be mounted inside a fixed groove formed in a recess on the outer surface of the magnet (230), and a force that pushes the stopper (220) outward may be applied to the elastic member (280), so that the outer end of the stopper (220) is fitted into the movement-restricting groove (290), thereby preventing the magnet (230) from being separated from the mounting hole (210) to the outside, and limiting the range of movement by being caught by the movement-restricting groove (290).

[0074]

[0075] Referring to FIG. 3, in the bicycle shoe coupling device according to the third embodiment of the present invention, the first coupling means (200) includes a mounting hole (210), a magnetic assembly, and a stopper (220).

[0078] More specifically, the magnetic assembly includes a first coupling member (240), a first magnet (250), a second coupling member (260), a second magnet (270), and an elastic member (280).

[0079] The first connecting member (240) has a head portion (241) formed at one end that protrudes outward.

[0080] The first magnet (250) is configured to be fitted around the circumference of the first coupling member (240), and has a ring shape with a mounting groove (251) formed on one surface thereof in which the head (241) of the first coupling member (240) is mounted, so that it can be fitted to the circumference of the first coupling member (240) through the other end of the first coupling member (240), and the head (241) of the first coupling member (240) is fitted into the mounting groove so that it can be mounted.

[0081] The second connecting member (260) is configured such that a head portion (261) protruding outward is formed at one end, and the other end is connected to the first connecting member (240).

[0082] The second magnet (270) is configured to be fitted around the circumference of the second coupling member (260), and has a ring shape with a mounting groove (271) formed on one surface thereof in which the head (261) of the second coupling member (260) is mounted, so that it can be fitted to the circumference of the second coupling member (260) through the other end of the second coupling member (260), and the head (261) of the second coupling member (260) is fitted into the mounting groove so that it can be mounted.

[0083] The elastic member (280) may be fitted to the circumference of the first coupling member (240) and the second coupling member (260) and may be interposed between the first magnet (250) and the second magnet (270) to apply a force to push the first magnet (250) and the second magnet (270) in a direction away from each other.

[0084] As configured as above, the magnetic assembly is configured so that the first magnet (250) is fitted to the circumference of the first coupling member (240) and the second magnet (270) is fitted to the circumference of the second coupling member (260), and then the elastic member (280) is placed between the first magnet (250) and the second magnet (270) so that it is fitted simultaneously to the circumference of the other end of the first coupling member (240) and the circumference of the other end of the second coupling member (260), and then the other end of the first coupling member (240) and the other end of the second coupling member (260) are coupled, so that the first magnet (250), the elastic member (280), and the second The magnetic assembly can be manufactured by assembling the magnets (270) in a sequentially interposed state, and in the assembled state, the first magnet (250) can be arranged to wrap the head (241) of the first coupling member (240) from the outside by the elastic member (280), and the second magnet (270) can be arranged to wrap the head (261) of the second coupling member (260) from the outside, so that the first magnet (250) and the second magnet (270) can be positioned at both ends of the magnetic assembly.

[0085] Meanwhile, the stopper (220) is provided to protrude inwardly from the middle of the mounting hole (210), and may be configured to include, for example, at least one protrusion protruding inwardly along the inner surface of the mounting hole (210), or, as another example, may be configured to have a ring shape as illustrated in the drawing, and is arranged in the space between the first magnet (250) and the second magnet (270) of the magnetic assembly when the magnetic assembly is positioned in the inner space of the mounting hole (210), so as to prevent the magnetic assembly from being separated from the mounting hole (210) by the first magnet (250) or the second magnet (270) being caught during the process of moving the magnetic assembly along the mounting hole (210), and at the same time, limit the range of movement of the magnetic assembly.

[0086] Accordingly, the shoe coupling device for a bicycle according to the third embodiment of the present invention prevents the magnetic assembly from being separated from the mounting hole (210) by the stopper (220), and furthermore, the magnetic assembly can have the first magnet (250) and the second magnet (270) positioned at both ends, so that when the magnetic assembly is mounted in the mounting hole (210), the magnetic force is directly transmitted between the shoe coupling means (300) and the first magnet (250) or the second magnet (270) without an intervening means such as a cover, thereby allowing the coupling force to be applied, thereby improving the coupling force between the shoe and the pedal frame (100), thereby providing the effect of preventing slipping of the shoe and enabling more stable use of the bicycle.

[0088] Meanwhile, the first magnet (250) and the second magnet (270) are configured to have an outer circumference corresponding to the shape and size of the inner circumference of the mounting hole (210), so that the first magnet (250) and the second magnet (270) of the magnetic assembly can be configured to slide along the mounting hole (210) while being aligned and inserted into the mounting hole (210).

[0089] Meanwhile, the first coupling member (240) and the second coupling member (260) may be coupled by a screw-fastening structure so that the length of the magnetic assembly can be adjusted. In this case, by adjusting the length of the magnetic assembly, the end of the magnetic assembly in the direction in which the shoe coupling means (300) is positioned is positioned on the same plane as the end of the mounting hole (210) so as to be in direct contact with the shoe coupling means (300) while the movement of the magnetic assembly is restricted by the stopper (220), or the end of the magnetic assembly in the direction in which the shoe coupling means (300) is positioned in the inner space of the mounting hole (210) rather than the end of the mounting hole (210) so as to be spaced apart from the shoe coupling means (300) while the shoe coupling means (300) is in contact with the pedal frame (100), so that the coupling force can be reduced compared to the state in which the shoe coupling means (300) and the end of the magnetic assembly are in direct contact. At this time, the coupling force can be adjusted by adjusting the distance between the end of the magnetic assembly in the direction in which the shoe coupling means (300) is positioned and the shoe coupling means (300). Consequently, the magnetic coupling force between the shoe coupling means (300) and the magnetic assembly can be adjusted by adjusting the length of the magnetic assembly.

[0090] Meanwhile, the stopper (220) may be formed integrally with the pedal frame (100) as shown in FIG. 3, or may be provided as a ring-shaped member formed as a separate body from the pedal frame (100), and may be configured to be coupled to the mounting hole (210) by a screw fastening structure.

[0091]

[0092] Referring to FIG. 4, in the bicycle shoe coupling device according to the fourth embodiment of the present invention, the first coupling means (200) includes a mounting hole (210), a magnetic assembly, and a stopper (220).

[0093] Looking at it in more detail, first, the mounting hole (210) is formed by penetrating the pedal frame (100) vertically to form a space in which the magnetic assembly is accommodated inside and can move up and down.

[0094] In addition, the magnetic assembly is provided so that the shoe coupling means (300) can be coupled to the pedal frame (100) by magnetic force and is accommodated in the internal space of the mounting hole (210), and is provided so as to be able to slide along the mounting hole (210), so that even if the pedal frame (100) is rotated and the upper and lower arrangement directions are changed, the magnetic assembly is moved in a direction approaching the shoe coupling means (300) provided on the user's shoe located above the pedal frame (100), as in the first coupling means (200) illustrated on the left side of the pedal frame (100) in FIG. 3, so that the magnetic assembly and the shoe coupling means (300) are coupled by magnetic force, and a coupling force is provided so that the pedal frame (100) and the shoe can be coupled.

[0095] More specifically, the magnetic assembly includes a first coupling member (240), a first magnet (250), a second coupling member (260), and a second magnet (270).

[0096] The first connecting member (240) has a head portion (241) formed at one end that protrudes outward.

[0097] The first magnet (250) is provided at one end of the first coupling member (240).

[0098] The second connecting member (260) is configured such that a head portion (261) protruding outward is formed at one end, and the other end is connected to the first connecting member (240).

[0099] The second magnet (270) is provided at one end of the second coupling member (260).

[0100] Meanwhile, the stopper (220) is provided to protrude inwardly from the middle of the mounting hole (210) of the mounting hole (210), and may be formed in the shape of a ring, for example, and is arranged in the space between the head (241) of the first coupling member (240) of the magnetic assembly and the head (261) of the second coupling member (260) when the magnetic assembly is positioned in the internal space of the mounting hole (210), so that the head (241) of the first coupling member (240) or the head (261) of the second coupling member (260) is caught during the process of moving the magnetic assembly along the mounting hole (210), thereby preventing the magnetic assembly from being separated from the mounting hole (210), and at the same time limiting the range of movement of the magnetic assembly.

[0101] Accordingly, the bicycle shoe coupling device according to the third embodiment of the present invention is provided with a first coupling member (240) having a first magnet (250) provided at one end of the first coupling member (240) and a second coupling member (260) having a second magnet (270) provided, and the first coupling member (240) and the second coupling member (260) are respectively fitted at both ends so that the first magnet (250) and the second magnet (270) are positioned on both sides with respect to the stopper (220) in the mounting hole (210) formed in the pedal frame (100), so that the other end of the first coupling member (240) and the other end of the second coupling member (260) are coupled to form a single magnetic assembly, and can be mounted on the pedal frame (100), thereby forming a single magnetic assembly. The magnet (250) and the second magnet (270) can be positioned so that the magnetic force can be directly transmitted between the shoe coupling means (300) and the first magnet (250) or the second magnet (270) without an intervening means such as a cover when the magnetic assembly is mounted in the mounting hole (210), thereby allowing the coupling force to be applied, thereby improving the coupling force between the shoe and the pedal frame (100), thereby preventing slipping of the shoe and providing the effect of enabling more stable use of the bicycle.

[0102] Meanwhile, the first coupling member (240) and the second coupling member (260) may be coupled by a screw-fastening structure so that the length of the magnetic assembly can be adjusted. In this case, by adjusting the length of the magnetic assembly, the end of the magnetic assembly in the direction in which the shoe coupling means (300) is positioned is positioned on the same plane as the end of the mounting hole (210) so as to be in direct contact with the shoe coupling means (300) while the movement of the magnetic assembly is restricted by the stopper (220), or the end of the magnetic assembly in the direction in which the shoe coupling means (300) is positioned in the inner space of the mounting hole (210) rather than the end of the mounting hole (210) so as to be spaced apart from the shoe coupling means (300) while the shoe coupling means (300) is in contact with the pedal frame (100), so that the coupling force can be reduced compared to the state in which the shoe coupling means (300) and the end of the magnetic assembly are in direct contact. At this time, the coupling force can be adjusted by adjusting the distance between the end of the magnetic assembly in the direction in which the shoe coupling means (300) is positioned and the shoe coupling means (300). Consequently, the magnetic coupling force between the shoe coupling means (300) and the magnetic assembly can be adjusted by adjusting the length of the magnetic assembly.

[0103] Meanwhile, the stopper (220) may be formed integrally with the pedal frame (100) as shown in FIG. 4, or may be provided as a ring-shaped member formed as a separate body from the pedal frame (100), and may be configured to be coupled to the mounting hole (210) by a screw fastening structure.

[0104] Meanwhile, the head portion (241) of the first coupling member (240) and the head portion (261) of the second coupling member (260) are configured to have an outer circumference having a shape and size corresponding to the inner circumference of the mounting hole (210), so that the first coupling member (240) and the second coupling member (260) of the magnetic assembly can be configured to slide along the mounting hole (210) while being aligned and fitted into the mounting hole (210).

[0105] Meanwhile, the stopper (220) may be formed integrally with the pedal frame (100) as shown in FIG. 4, or may be provided as a ring-shaped member formed as a separate body from the pedal frame (100), and may be configured to be coupled to the mounting hole (210) by a screw fastening structure.

[0106] Meanwhile, a fitting groove may be formed in a recessed manner in the head portion (241) of the first coupling member (240) and the head portion (261) of the second coupling member (260), and the first magnet (250) may be configured to be fitted into and fixed in the fitting groove formed in the head portion (241) of the first coupling member (240), and the second magnet (270) may be configured to be fitted into and fixed in the fitting groove formed in the head portion (261) of the second coupling member (260).

[0107] At this time, the entire first coupling member (240) and the second coupling member (260) or the head portion (241) of the first coupling member (240) and the head portion (261) of the second coupling member (260) are made of a ferromagnetic material, and the ferromagnetic material absorbs the magnetic force of the magnet and blocks the magnetic force from leaking to the outside, so that the magnetic force of the first magnet (250) and the second magnet (270) fitted into the fitting groove made of the ferromagnetic material can be configured to minimize the magnetic force from leaking to the outside, so that a stronger bonding force can be applied to the shoe coupling means (300). Examples of the ferromagnetic material that can be used include iron, Permalloy, which is an alloy of iron and nickel, aluminum, silicon, Sendust, which is an alloy of iron, and silicon steel, which is an alloy of iron and silicon.

[0108]

[0109] Meanwhile, in the shoe coupling device for a bicycle according to an embodiment of the present invention, the magnetic assembly of the first coupling means (200) may be configured to be positioned on a plane with the upper or lower surface of the pedal frame (100) while the movement is restricted by the stopper (220) in a direction adjacent to the shoe coupling means (300), or, as shown in FIGS. 3 and 4, in the shoe coupling device for a bicycle according to an embodiment of the present invention, the magnetic assembly of the first coupling means (200) may be configured to be positioned so as to be exposed to the outside by protruding further outward than the upper or lower surface of the pedal frame (100) while the movement is restricted by the stopper (220) in a direction adjacent to the shoe coupling means (300), and in this case, the lower surface of the shoe coupling means (300) may be configured to wrap the end of the magnetic assembly exposed to the outside of the pedal frame (100) from the outside to minimize the leakage of magnetic force, so as to simultaneously wrap the entire first coupling means (200) from the outside as shown in FIG. 3. A leakage blocking groove may be formed, or a leakage blocking groove may be formed at a position corresponding to each first coupling means (200) so as to surround each first coupling means (200) from the outside as shown in FIG. 4, and may include a magnetic contact surface that comes into contact with the upper or lower surface of the magnetic assembly, and a side blocking wall that is formed to protrude and surround the upper or lower surface of the magnetic assembly along the periphery of the contact surface. In this case, as the area in contact with the magnetic assembly increases, a more improved coupling force can be provided.

[0110] At this time, the part of the shoe coupling means (300) that comes into contact with the end of the magnetic assembly of the first coupling means (200) is made of a ferromagnetic material, and the ferromagnetic material absorbs the magnetic force of the magnet and blocks the magnetic force from leaking to the outside, thereby minimizing the magnetic force from leaking to the outside, and can be configured so that a stronger bonding force can be applied to the shoe coupling means (300). Examples of the ferromagnetic material that can be used include iron, Permalloy, which is an alloy of iron and nickel, Sendust, which is an alloy of aluminum, silicon, and iron, and silicon steel, which is an alloy of iron and silicon.

[0111] FIG. 5 is a perspective view showing a pedal frame (100), a raising / lowering housing (110), and a first coupling means (200) in a shoe coupling device for a bicycle according to a fifth embodiment of the present invention, FIG. 6 is a side sectional view showing a pedal frame (100), a raising / lowering housing (110), and a first coupling means (200) in a shoe coupling device for a bicycle according to a fifth embodiment of the present invention, FIG. 7 is a side sectional view showing a pedal frame (100), a raising / lowering housing (110), and a first coupling means (200) in a shoe coupling device for a bicycle according to a sixth embodiment of the present invention, and FIG. 8 is a side sectional view showing a pedal frame (100), a raising / lowering housing (110), and a first coupling means (200) in a shoe coupling device for a bicycle according to a seventh embodiment of the present invention.

[0112] Referring to FIGS. 5 to 8, the shoe coupling device for a bicycle according to the fifth to seventh embodiments of the present invention further includes, in addition to a pedal frame (100), a first coupling means (200), and a shoe coupling means (300), a raising / lowering housing (110) that is provided so as to be mounted on the pedal frame (100). In this case, in the fifth to seventh embodiments, unlike the first to fourth embodiments, the first coupling means (200) is provided on the raising / lowering housing (110) that is mounted on the pedal frame (100), not on the pedal frame (100). This will be described in more detail as follows.

[0113] First, referring to FIGS. 5 and 6, in the shoe coupling device for a bicycle according to the fifth embodiment of the present invention, the first coupling means (200) includes a mounting hole (210), a pair of stoppers (220), and a magnet, like the shoe coupling device for a bicycle according to the first embodiment of the present invention. However, the mounting hole (210) is different in that it is formed by vertically penetrating the raising / lowering housing (110) rather than the pedal frame (100). In the case of the pair of stoppers (220) and the magnet, the configuration and the operating method of the shoe coupling device for a bicycle according to the first embodiment of the present invention are the same, so that redundant expressions are omitted for the sake of concise description of the invention.

[0114] In addition, referring to FIG. 7, in the shoe coupling device for a bicycle according to the sixth embodiment of the present invention, the first coupling means (200) includes a mounting hole (210), a magnetic assembly, and a stopper (220) like the shoe coupling device for a bicycle according to the third embodiment of the present invention. However, the mounting hole (210) is different in that it is formed by vertically penetrating the raising / lowering housing (110) rather than the pedal frame (100). In the case of the magnetic assembly and the stopper (220), the configuration and operating method of the shoe coupling device for a bicycle according to the third embodiment of the present invention are the same, so that redundant expressions are omitted for the sake of concise description of the invention.

[0115] In addition, referring to FIG. 8, in the shoe coupling device for a bicycle according to the seventh embodiment of the present invention, the first coupling means (200) includes a mounting hole (210), a magnetic assembly, and a stopper (220) like the shoe coupling device for a bicycle according to the fourth embodiment of the present invention. However, the mounting hole (210) is different in that it is formed by vertically penetrating the raising / lowering housing (110) rather than the pedal frame (100). In the case of the magnetic assembly and the stopper (220), the configuration and operating method of the shoe coupling device for a bicycle according to the third embodiment of the present invention are the same, so that redundant expressions are omitted for the sake of concise description of the invention.

[0116] Meanwhile, although not shown in the drawing, in the bicycle shoe coupling device according to another embodiment of the present invention, the first coupling means (200) includes a mounting hole (210), a stopper (220), a magnet (230), and a movement-limiting groove (290), like the bicycle shoe coupling device according to the second embodiment of the present invention. However, the mounting hole (210) is different in that it is formed by vertically penetrating the raising / lowering housing (110) rather than the pedal frame (100). In the case of the stopper (220), the magnet (230), and the movement-limiting groove (290), the configuration and the operating method of the bicycle shoe coupling device according to the second embodiment of the present invention are the same, so that redundant expressions are omitted for the sake of concise description of the invention.

[0117] Meanwhile, when the shoe coupling means (300) including the magnetic body and the ferromagnetic body of the first coupling means (200) provided in the lift housing (110) are positioned close to each other, the lift housing (110) can be raised upward toward the shoe coupling means (300).

[0118] At this time, the raising / lowering housing (110) can be raised to a position where the upper surface of the raising / lowering housing (110) is outside the upper surface of the pedal frame (100), such as the raising / lowering housing (110) shown on the left among the plurality of raising / lowering housings (110) mounted on the pedal frame (100) in FIGS. 6 to 8, thereby enabling the user to more easily apply an external force toward the raising / lowering housing (110).

[0119] In addition, the ascending and descending housing (110) is made of a non-magnetic material, and when the ascending and descending housing (110) comes into contact with the shoe coupling means (300), the magnetic material built into the mounting hole (210) of the first coupling means (200) moves toward the shoe coupling means (300), so that the ascending and descending housing (110) can be coupled to the shoe coupling means (300) by magnetic force.

[0120]

[0121] FIG. 9 is a side view illustrating a shoe coupling device for a bicycle according to an eighth embodiment of the present invention, FIG. 10 is a side view illustrating a shoe coupling device for a bicycle according to a ninth embodiment of the present invention, and FIG. 11 is a side view illustrating a shoe coupling device for a bicycle according to a tenth embodiment of the present invention.

[0122] Referring to FIGS. 9 to 11, a shoe coupling device for a bicycle according to an embodiment of the present invention, when including a raising / lowering housing (110) as described above, may further include a second coupling means (400) provided such that one end is hinge-coupled to the raising / lowering housing (110) and the other end is capable of contacting and separating from the lower part of the shoe.

[0123] First, the second coupling means (400) may be provided such that one end is hinge-connected to the raising / lowering housing (110) and the other end can be brought into contact with and separated from the bottom of the shoe, thereby increasing the contact area with the shoe, thereby allowing the coupling force between the shoe coupling means (300) and the pedal to be more firmly maintained.

[0124] In addition, the second coupling means (400) is hinge-coupled by the pedal frame (100) and the support shaft (430) so as to be able to be raised and lowered in conjunction with the raising and lowering movement of the raising and lowering housing (110).

[0125] More specifically, the second coupling means (400) may be configured such that when the elevating housing (110) is lowered, one end coupled to the elevating housing (110) is lowered relative to the support shaft (430) and the other end is raised so that the other end can come into contact with the lower part of the shoe, and conversely, when the elevating housing (110) is raised, one end coupled to the elevating housing (110) is raised relative to the support shaft (430) and the other end is lowered so that the other end can be separated from the lower part of the shoe.

[0126] Meanwhile, the raising / lowering housing (110) can be raised to a position where the upper surface of the raising / lowering housing (110) is outside the upper surface of the pedal frame (100), thereby allowing the user to more easily apply an external force toward the raising / lowering housing (110), so that the second coupling means (400) can be more easily raised / lowered to make contact with and separate from the shoe.

[0127] In addition, when a strong bonding force is required between the shoe bonding means (300) and the first bonding means (200), such as when pedaling, through the interlocking second bonding means (400) of the ascending and descending housing (110), the second bonding means (400) and the lower part of the shoe can be brought into contact to assist the bonding force, and when separation between the shoe bonding means (300) and the first bonding means (200) is required, the second bonding means (400) is separated from the lower part of the shoe so that separation can be achieved more quickly, thereby assisting stable pedaling and assisting rapid separation of the shoe bonding means (300) and the first bonding means (200), thereby providing the effect of preventing a falling accident.

[0128] Meanwhile, the second coupling means (400) may include a leverage frame (410) and a pin member (420).

[0129] The leverage frame (410) may be provided with at least one end hingedly connected to the lifting housing (110), and may be configured such that the middle portion between the one end and the other end is hingedly connected to the pedal frame (100) by a support shaft (430) so that the other end can be raised or lowered toward the upper or lower surface of the pedal frame (100).

[0130] At this time, the leverage frame (410) may be formed to extend toward the front and rear of the pedal frame (100) as shown in the drawing, and of course, may be formed to extend toward both sides of the pedal frame (100).

[0131] In addition, the leverage frame (410) may be provided such that the other end, which is the free end of the leverage frame (410), protrudes toward the outside of the pedal frame (100).

[0132] In particular, by configuring the other end of the leverage frame (410) to protrude toward the outside of the pedal frame (100), the contact point with the shoe can be further expanded, thereby further improving the bonding force between the second coupling means (400) and the shoe.

[0133] Meanwhile, the pin member (420) is provided at the other end, which is the free end of the leverage frame (410), and may be provided so as to be in contact with or separated from the lower surface of the shoe and may be provided at least one or more.

[0134] At this time, the pin member (420) can be formed to extend in one or more directions selected from the upper and lower directions based on the pedal frame (100), and in particular, the state of connection with the shoe can be varied through the raising and lowering of the pin member (420) depending on the position of the raising and lowering housing (110), thereby improving the connection strength or ensuring ease of separation.

[0135] More specifically, when an external force is applied to the raising / lowering housing (110), the pin member (420) is raised so that the upper end of the pin member (420) leaves the upper surface of the pedal frame (100) and comes into contact with the lower surface of the shoe. In particular, the pin member (420) may be configured to come into contact with the shoe only when an external force is applied to the raising / lowering housing (110), thereby improving the fastening force or ensuring ease of separation as needed.

[0136]

[0137] Meanwhile, referring to FIGS. 9 to 11, more diverse embodiments of the shoe coupling means (300) in the shoe coupling device for a bicycle according to an embodiment of the present invention will be described as follows.

[0138] As illustrated in FIG. 9, the shoe coupling means (300) may include a pedal fastening means (310), a shoe fastening means (320), and a position restraining means (330).

[0139] First, the pedal fastening means (310) can be detachably attached to the lower surface of the shoe.

[0140] More specifically, the pedal fastening means (310) may include a first pedal fastening body (311a) and a connecting member (312a, 312b).

[0141] In addition, the first pedal fastening body (311a) may be formed with at least one coupling protrusion that protrudes downward from the first pedal fastening body (311a) to mechanically couple with the pedal frame (100).

[0142] And, at least one connecting member (312a, 312b) may be provided to connect the first pedal fastening body (311a) and the shoe, and at this time, the connecting member (312a, 312b) may include at least one selected from an elastic body having a predetermined elastic restoring force and a magnetic body having a predetermined magnetic force.

[0143] In particular, as illustrated in Fig. 9, when the connecting member (312a) is provided with an elastic body, one end of the elastic body is provided to be coupled with the lower surface of the shoe, and the other end of the elastic body is provided to be coupled with the upper portion of the first pedal fastening body (311a).

[0144] Alternatively, as illustrated in FIG. 10, when the connecting member (312b) is provided with a magnetic body, a soft magnetic pad may be used as the connecting member, and the upper surface of the magnetic pad is attached to the lower surface of the shoe, and the lower surface of the magnetic pad is provided to be attached to the upper surface of the first pedal body.

[0145] At this time, the magnetic pad may be configured to have a lower magnetic force than the magnetic body of the first coupling means (200) described above.

[0146] Next, the shoe fastening means (320) is provided to mutually connect the first pedal fastening body (311a) and the lower surface of the shoe so that the position of the free end of the first pedal fastening body (311a) can move freely within a certain area when the pedal fastening means (310) is coupled to the shoe.

[0147] At this time, the shoe fastening means (320) may use a bolt having a predetermined length, and of course, at least one may be provided.

[0148] In addition, the shoe fastening means (320) may use at least one selected from among a hexagonal bolt, a round head screw, a countersunk head screw, and a cross-slotted screw, but is not limited thereto.

[0149] At this time, the shoe fastening means (320) is fastened to the shoe while simultaneously penetrating the position restraint means (330) and the first pedal fastening body (311a).

[0150] And, the position restraint means (330) is provided to limit the range of movement of the first pedal fastening body (311a), and is fastened to the shoe fastening means (320) so that it can be raised and lowered.

[0151] In particular, when the position restraint means (330) comes into contact with the raising / lowering housing (110), the first pedal engaging body (311a) is moved to descend along the position restraint means (330).

[0152] At this time, at least one coupling protrusion formed on the first pedal fastening body (311a) moves toward the pedal frame (100), so that the coupling protrusion and the pedal frame (100) are mutually coupled at at least one point.

[0153] That is, as configured as described above, while the connection is made based on magnetic force, the pedal connection means (310) is raised and lowered simultaneously, so that the connection point is expanded, thereby ensuring a more stable connection force.

[0154] Meanwhile, referring to FIG. 11, another embodiment of the shoe coupling means (300) will be described in more detail.

[0155] As illustrated in Fig. 11, the shoe coupling means (300) includes a pedal fastening means (310), a shoe fastening means (320), and a position-restricting means (330). First, at least one pedal fastening means (310) is provided, and is provided to be detachable from the lower surface of the shoe. At this time, the pedal fastening means (310) may be configured to include a second pedal fastening body (311b) provided so that the position of the free end is variable.

[0156] In addition, the shoe fastening means (320) may be provided to interconnect the position restraining means (330) and the lower surface of the shoe, and as described above, a bolt having a predetermined length may be used, and of course, at least one may be provided.

[0157] In addition, the position restraint means (330) may be provided to limit the movement area of ​​the free end of the second pedal fastening body (311b), and may be made of a ferromagnetic material including metal.

[0158] In addition, the shoe fastening means (320) may use at least one selected from among a hexagonal bolt, a round head screw, a countersunk head screw, and a cross-slotted screw, but is not limited thereto.

[0159] In particular, the second pedal fastening body (311b) has one end of the second pedal fastening body (311b) hinge-connected to the position restraining means (330).

[0160] At this time, the second pedal fastening bodies (311b) can be arranged at equal intervals with respect to the shoe fastening means (320).

[0161] More specifically, the other end of the second pedal fastening body (311b) can be configured to be coupled to or separated from the pedal frame (100) in conjunction with the contact state of the position restraining means (330) and the raising / lowering housing (110).

[0162] In addition, although not specifically shown in the drawing, the second pedal fastening body (311b) can be fastened to a connecting member (312a, 312b) including at least one selected from among an elastic body and a magnetic body that are coupled to the lower surface of the shoe, as shown in FIG. 9 or FIG. 10 described above.

[0163] In particular, when the ascending and descending housing (110) and the position restraining means (330) are mutually coupled by magnetic force, the second pedal fastening body (311b) descends and is coupled with the pedal frame (100).

[0164] And, when the second pedal fastening body (311b) is coupled to the lower surface of the shoe through a connecting member, it is obvious that it can be driven to rise upward when the raising / lowering housing (110) and the position restraining means (330) are separated from each other.

[0165] That is, as the position of the pedal fastening means (310) returns to its original position after the user removes the shoe from the pedal, the second pedal fastening body (311b) rises again, minimizing the phenomenon of the coupling protrusion coming into direct contact with the ground, and thus, of course, ensuring improved durability.
