  Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention. Hereinafter, embodiments will be described with reference to the drawings. In the description of the drawings, the same or similar parts may be denoted by the same reference numerals, and redundant description may be omitted. The drawings are schematic, and the relationship between the thickness and the planar dimensions, the ratio, and the like may be different from the actual ones. In addition, for convenience of explanation, there may be a case where the drawings have different dimensional relationships or ratios.

  FIG. 1 schematically shows an example of a spiked shoe 100. In the present embodiment, the spike shoe 100 includes an upper 110, a sole 120, a spike 130, and a spike adjustment mechanism 140. Upper 110 is coupled to sole 120. The spike shoe 100 may be a golf shoe.

  The sole 120 houses the spike adjustment mechanism 140. The sole 120 has a bottom surface 122 and a side surface 124. In the present embodiment, the bottom surface 122 of the sole 120 is formed with an opening or a recess for taking in and out the spike 130. The structure of the sole 120 is not particularly limited, but may be a single-layer structure or a multilayer structure including a plurality of soles such as an outsole and a midsole.

  The spike 130 protrudes from the bottom surface 122 of the sole 120 and improves the grip force with respect to the ground. The material of the spike 130 is not particularly limited, but may be made of metal or plastic. The spike 130 may be detachably coupled to the spike adjustment mechanism 140. The spike 130 may have a through hole 132. By inserting and rotating a jig into the through hole 132, the spike 130 can be easily attached and detached. The through hole 132 may be an example of a jig mounting portion on which a jig for facilitating the attachment / detachment of the spike 130 is mounted.

  The spike adjustment mechanism 140 puts and removes the spike 130 from the bottom surface 122 of the sole 120 of the spike shoe 100. In the present embodiment, the spike adjustment mechanism 140 includes a switching lever 142 that switches whether the spike 130 protrudes from the bottom surface 122 of the sole 120. The switching lever 142 may be exposed to the outside of the sole 120 from the side surface 124 of the sole 120.

  When the user of the spike shoe 100 operates the switching lever 142 so that the spike 130 protrudes from the bottom surface 122 of the sole 120, the spike adjustment mechanism 140 is connected to the sole via the opening formed in the bottom surface 122 of the sole 120. The spike 130 protrudes from the bottom surface 122 of 120. On the other hand, when the user of the spike shoe 100 operates the switching lever 142 to accommodate the spike 130 in the sole 120, the spike adjustment mechanism 140 accommodates the spike 130 in the sole 120.

  The use of spike shoes having metal spikes may be prohibited or restricted in order to prevent the grass spikes, green, indoor flooring, etc. from being damaged by the metal spikes. For example, in a golf course, when entering an office, clubhouse, etc., it may be required to remove spikes or change to non-spiked shoes.

  When using spiked shoes with plastic spikes, the user must be careful not to tip over when walking on a wet or hard floor. Also, if you walk on concrete, asphalt, etc. while wearing spiked shoes with plastic spikes, the lifespan of the spikes will decrease.

  In the present embodiment, the spike shoe 100 includes a spike adjustment mechanism 140, and the spike 130 can be accommodated inside the sole 120 as necessary. Thereby, it is possible to prevent the spike 130 from damaging the lawn, the green, the indoor flooring, and the like. Moreover, a user's fall can be suppressed. Furthermore, the consumption of the spike 130 can be reduced. Further, the spike 130 can be accommodated in the sole 120 by operating the switching lever 142. Thereby, the spike 130 can be accommodated while wearing the spike shoes 100.

  In the present embodiment, the case where the switching lever 142 is disposed on the side surface 124 of the sole 120 has been described. However, the position of the switching lever 142 is not limited to this. The switching lever 142 may be disposed on the upper 110. The switching lever 142 may be disposed on the tongue (tongue) of the spike shoe 100.

  FIG. 2 schematically shows an example of a side view of the spike adjustment mechanism 140. FIG. 3 schematically shows an example of a bottom view of the spike adjustment mechanism 140. FIG. 2 shows an AA ′ cross section of FIG. FIG. 2 shows the spike adjustment mechanism 140 with the sole 120 and the spike 130. 3 shows a view of the spike adjustment mechanism 140 of FIG. 2 as viewed from below in FIG. The spike adjustment mechanism 140 will be described with reference to FIGS. 2 and 3.

  In the present embodiment, the spike adjustment mechanism 140 includes an actuator 210, a pressurizing unit 220, a pipe 230, and a switching unit 240. The pressurizing unit 220 may include an air pump 222, a suction valve 224, and a discharge valve 226. The pipe 230 may include a pipe 232 and a pipe 234. The air pump 222 may be an example of a pump.

  The spike adjustment mechanism 140 may include a plurality of actuators 210. In this embodiment, one actuator 210 is coupled per spike 130. Thereby, the total value of the volumes of the actuator 210 can be reduced. As a result, the response speed of the spike 130 can be improved.

  The actuator 210 converts the pressure energy of the working fluid into mechanical energy. The actuator 210 moves the spike 130 in and out of the sole 120 of the spike shoe 100 by the pressure of the working fluid. When the pressure of the working fluid inside the actuator 210 becomes larger than a specific threshold value, the spike 130 protrudes from the bottom surface 122 of the sole 120. When the pressure of the working fluid inside the actuator 210 becomes smaller than the inherent threshold value, the spike 130 is accommodated inside the sole 120.

  The working fluid may be a gas. Thereby, compared with the case where a liquid working fluid is used, the spike shoes 100 can be reduced in weight. The working fluid may be air. Thereby, outside air can be sucked and used as a working fluid. As a result, the structure of the spike adjustment mechanism 140 can be simplified.

  In the present embodiment, the actuator 210 is accommodated in an opening 250 formed in the sole 120. An elastic body such as rubber may be fitted in the gap between the actuator 210 and the opening 250. Further, the gap between the actuator 210 and the opening 250 may be sealed with resin or the like. Thereby, it is possible to prevent water, dirt, dust, and the like from entering the inside of the spike shoe 100 from the gap between the actuator 210 and the opening 250.

  The pressurizing unit 220 pressurizes the working fluid of the actuator 210. The pressurizing part 220 may be disposed on the heel part of the sole 120. Thereby, the working fluid of the actuator 210 can be pressurized using the weight of the user.

  The air pump 222 supplies a working fluid to the actuator 210. In the present embodiment, the air pump 222 sucks air from the outside of the spike adjustment mechanism 140 via the suction valve 224. When the user walks with wearing the spike shoes 100, the air pump 222 is pressed. Thereby, the air pump 222 discharges internal air via the discharge valve 226. When the air discharged from the air pump 222 is supplied to the actuator 210, the pressure inside the actuator 210 increases.

  The suction valve 224 is disposed on the suction port side of the air pump 222. The suction valve 224 may be a one-way valve. The suction valve 224 circulates air, which is an example of a working fluid, from the outside of the spike adjustment mechanism 140 toward the inside of the air pump 222. On the other hand, the suction valve 224 prevents the working fluid from being discharged from the inside of the air pump 222 toward the outside of the spike adjustment mechanism 140.

  The discharge valve 226 is disposed on the discharge port side of the air pump 222. The suction valve 224 may be a one-way valve. The discharge valve 226 causes the working fluid to flow from the inside of the air pump 222 toward the actuator 210. On the other hand, the discharge valve 226 suppresses the working fluid from flowing from the actuator 210 toward the inside of the air pump 222.

  The piping 230 circulates the working fluid between the pressurizing unit 220 and each of the plurality of actuators 210. The piping 232 causes the working fluid to flow between the discharge valve 226 of the pressurizing unit 220 and the switching unit 240. The piping 234 causes the working fluid to flow between the switching unit 240 and each of the plurality of actuators 210.

  The switching unit 240 is arranged in a part of the pipe 230 and switches whether to seal the inside of the pipe 230. Here, sealing means that leakage of the working fluid is suppressed to such an extent that most of the working fluid supplied from the pressurizing unit 220 to the switching unit 240 can be supplied to the plurality of actuators 210. The present invention is not limited to the case where the fluid is completely contained in the pipe 230.

  In the present embodiment, the switching unit 240 is disposed between the pipe 232 and the pipe 234, and the opening 242 is formed in the switching unit 240. The switching unit 240 has a switching lever 142, and the user operates the switching lever 142 to switch whether the switching unit 240 seals the inside of the pipe 230.

  When the user of the spike shoe 100 operates the switching lever 142 to accommodate the spike 130 in the sole 120, the switching unit 240 pipes a part of the working fluid inside the pipe 230 through the opening 242. 230 is discharged to the outside. As a result, the pressure of the working fluid inside the actuator 210 becomes approximately the same as the atmospheric pressure. As a result, the spike 130 is accommodated inside the sole 120.

  On the other hand, when the user of the spike shoe 100 operates the switching lever 142 so that the spike 130 protrudes from the sole 120, the switching unit 240 indicates that the working fluid inside the pipe 230 is discharged from the opening 242 to the outside. Suppress. Thereby, the working fluid supplied from the pressurizing unit 220 to the switching unit 240 is supplied to the plurality of actuators 210. As a result, the pressure of the working fluid inside the actuator 210 becomes larger than the atmospheric pressure, and the spike 130 protrudes from the sole 120.

  In the present embodiment, the case where the pressurizing unit 220 increases the pressure of the working fluid inside the actuator 210 by supplying the external air sucked from the suction valve 224 to the actuator 210 has been described. Further, the case where the switching unit 240 reduces the pressure of the working fluid inside the actuator 210 by discharging a part of the working fluid inside the pipe 230 to the outside of the pipe 230 has been described. However, the spike adjustment mechanism 140 is not limited to this. The storage unit may further include a storage unit that stores the working fluid, and the pressurization unit 220 may supply the working fluid sucked from the storage unit to the actuator 210. The switching unit 240 may discharge a part of the working fluid inside the pipe 230 to the storage unit.

  In the present embodiment, the case where the actuator 210 is accommodated in the opening 250 that penetrates the sole 120 has been described. However, the arrangement of the actuator 210 is not limited to this. The actuator 210 may be disposed in a recess formed in the bottom surface 122 of the sole 120 or may be embedded in the sole 120.

  FIG. 4 schematically shows an example of a sectional view of the actuator 210. In the present embodiment, the actuator 210 has a diaphragm 410 and a cylinder 420. The cylinder 420 includes a cylinder body 422, a guide member 424, and a seal member 428. A chamber 430 for storing a working fluid is formed inside the actuator 210. In FIG. 4, the drawing is performed such that there is a gap between each part for the purpose of simplifying the explanation. However, in an actual embodiment, each part of the actuator 210 is coupled without a gap.

  The diaphragm 410 separates the inside and the outside of the chamber 430. A spike 130 is coupled to the surface of the diaphragm 410 that contacts the outside of the chamber 430. Spike 130 may be removably coupled to diaphragm 410. Diaphragm 410 may have a threaded hole to which spike 130 is attached. The diaphragm 410 may be formed of an elastic body such as rubber.

  The diaphragm 410 moves the spike 130 in the vertical direction in the drawing by the pressure of the working fluid inside the chamber 430. When the pressure of the working fluid inside the chamber 430 becomes larger than a specific threshold value, the diaphragm 410 moves downward in the drawing until it comes into contact with the guide member 424. Thereby, the spike 130 moves downward in the figure. On the other hand, when the pressure of the working fluid inside the chamber 430 becomes smaller than a specific threshold value, the diaphragm 410 moves downward in the drawing. Thereby, the spike 130 moves upward in the figure.

  The cylinder body 422 forms a chamber 430 together with the diaphragm 410. The cylinder body 422 may have a hollow shape. The cylinder body 422 is formed with an opening 425 in which the diaphragm 410 is disposed and an opening 426 through which the working fluid flows between the chamber 430 and the pipe 234.

  The guide member 424 guides the movement of the spike 130. Thereby, the spike 130 can move linearly. The guide member 424 is coupled to the cylinder body 422 so that the diaphragm 410 and the cylinder body 422 are brought into close contact with each other. As a result, the working fluid can be prevented from being discharged to the outside through the gap between the diaphragm 410 and the cylinder body 422.

  The seal member 428 is disposed on the surface of the guide member 424 on the bottom surface 122 side. The seal member 428 is formed with a through hole through which the spike 130 enters and exits. The seal member 428 may be formed of an elastic material such as rubber or resin. The planar shape of the seal member 428 may be determined according to the shape of the opening 250 of the sole 120. Thereby, it is possible to prevent water, dirt, dust, and the like from entering the inside of the spike shoe 100 from the gap between the actuator 210 and the opening 250. The planar shape of the seal member 428 may be a ring shape.

  In the present embodiment, the case where the actuator 210 is a single-acting cylinder having the diaphragm 410 and the cylinder 420 has been described. However, the actuator 210 is not limited to this. The actuator 210 may be a single acting cylinder in which an elastic body such as a spring and a piston are combined instead of the diaphragm 410, or may be a backward acting cylinder. However, by using the diaphragm 410, inflow of water, soil, dust, or the like into the chamber 430 can be prevented.

  FIG. 5 schematically shows an example of a side view of the pressure unit 220. FIG. 6 schematically shows an example of a top view of the pressure unit 220. The pressurizing unit 220 will be described with reference to FIGS. 5 and 6. In the present embodiment, the pressurizing unit 220 includes an air pump 222, a suction valve 224, and a discharge valve 226. The air pump 222 includes a diaphragm 512, an elastic body 514, and a support portion 522. The diaphragm 512 and the support portion 522 are combined to form a chamber 530 that stores the working fluid inside the air pump 222.

  The diaphragm 512 causes the working fluid inside the chamber 530 to flow by deforming its shape. Diaphragm 512 may have a hollow hemispherical or semi-ellipsoidal shape. A suction port 624 and a discharge port 626 are formed in the diaphragm 512. The working fluid sucked from the suction valve 224 flows into the chamber 530 through the suction port 624. The working fluid inside the chamber 530 is discharged from the inside of the chamber 530 through the discharge port 626. The working fluid discharged from the chamber 530 is supplied to the actuator 210 via the discharge valve 226. The diaphragm 512 may be formed of a flexible material such as rubber or a resin sheet.

  The elastic body 514 restores the shape of the diaphragm 512 that has been pressed and deformed. The elastic body 514 is disposed inside the chamber 530. One end of the elastic body 514 is coupled to the support portion 522. The other end of the elastic body 514 is coupled to the diaphragm 512. In the present embodiment, a spring is used as the elastic body 514.

  Next, the operation of the air pump 222 will be described. When the user walks with the spike shoes 100 on, the diaphragm 512 is pressed and deformed by the weight of the user. Thereby, the volume of the chamber 530 decreases. As a result, the air pump 222 discharges the working fluid inside the chamber 530 via the discharge valve 226. On the other hand, when the force that presses the diaphragm 512 decreases, the shape of the diaphragm 512 is restored to the shape before being pressed by the elastic force of the elastic body 514. As a result, the air pump 222 sucks the working fluid into the chamber 530 via the suction valve 224.

  FIG. 7 schematically shows an example of a cross-sectional view of the intake valve 224. The discharge valve 226 may have the same configuration as the intake valve 224. In the present embodiment, the intake valve 224 includes a valve box 710 and a valve box 720, a valve body 732, an elastic body 734, and a valve seat 736. The valve box 710 is formed with a discharge port 712 that discharges the working fluid from the inside of the valve box 710 to the outside of the valve box 710. The valve box 720 is formed with an inlet 722 through which the working fluid flows from the outside of the valve box 720 into the valve box 720.

  The valve body 732 and the elastic body 734 are disposed inside the valve box 710. One end of the elastic body 734 is coupled to the inner surface of the valve box 710. The other end of the elastic body 734 is coupled to the valve body 732. The valve seat 736 is disposed inside the valve box 720. The valve box 710 and the valve box 720 are coupled so that the valve box 720 covers the outside of the valve box 710. As a result, the elastic body 734 presses the valve body 732 against the valve seat 736. As a result, the working fluid can flow from the inlet 722 toward the outlet 712, but cannot flow from the outlet 712 toward the inlet 722. By forming the valve box from the valve box 710 and the valve box 720, the intake valve 224 can be easily assembled.

  FIG. 8 schematically illustrates an example of a cross-sectional view of the switching unit 240 in the closed state. FIG. 9 schematically shows an example of a cross-sectional view of the switching unit 240 in the open state. The switching unit 240 will be described with reference to FIGS. 8 and 9. In the present embodiment, the switching unit 240 includes a distribution unit 810 and an opening / closing unit 820. The distribution unit 810 includes a switching unit main body 812 and a lid member 814. The opening / closing part 820 includes a closing member 822, a pushing member 824, a support member 826, and a lid member 828.

  The distribution unit 810 distributes the working fluid. In the present embodiment, the switching unit main body 812 has a hollow shape, and an opening 816 is formed at one end. The lid member 814 closes the opening 816 of the switching unit main body 812. As a result, a flow path 830 through which the working fluid flows is formed inside the switching unit main body 812. The switching unit main body 812 is formed with an inlet 832, an outlet 834, and an opening 836 for pressure adjustment.

  The working fluid supplied from the pressurizing unit 220 flows into the flow path 830 through the inflow port 832. The working fluid inside the flow path 830 is discharged from the inside of the flow path 830 through the discharge port 834. The opening 836 opens the inside of the flow path 830 to the outside of the spike adjustment mechanism 140. When the opening 836 is open to the outside, the working fluid inside the flow path 830 is discharged to the outside through the opening 836.

  The opening / closing part 820 opens and closes the opening 836. The closing member 822 is pushed into the opening 836 by the pushing member 824 and closes the opening 836. The closing member 822 is pushed out from the opening 836 by the pressure of the working fluid inside the flow path 830 to open the opening 836. In the present embodiment, the closing member 822 has an elastic body 842 at one end. The elastic body 842 contacts the wall surface of the opening 836 when the closing member 822 closes the opening 836. Thereby, the opening 836 can be sealed. The other end of the closing member 822 is disposed to face the pushing member 824.

  In the present embodiment, the pushing member 824 includes a rotating portion 844, a protruding portion 846, a switching lever 142, and a support pin 848. The rotating unit 844 rotates around the support pin 848 as a rotation axis. The rotating unit 844 may have a substantially disk shape or a substantially spherical shape. The protruding portion 846 is disposed on a part of the outer periphery of the rotating portion 844. The protruding portion 846 may be disposed at a position facing the closing member 822. The switching lever 142 is disposed on a part of the outer periphery of the rotating unit 844. The protruding portion 846 and the switching lever 142 may be disposed at substantially symmetrical positions with the support pin 848 as the center. The rotating portion 844, the protruding portion 846, and the switching lever 142 may be formed by integral molding. In the present embodiment, the support pin 848 supports the rotating unit 844 so as to be rotatable with respect to the lid member 828.

  The support member 826 supports the pushing member 824. In the present embodiment, the support member 826 supports the lid member 828 on which the pushing member 824 is disposed. The support member 826 has a hollow shape, and a lid member 828 is disposed at one end. The other end of the support member 826 is coupled to the switching unit main body 812. At the other end of the support member 826, the wall surface of the support member 826 may be disposed so as to surround the opening 836. An opening 242 is formed in a part of the wall surface of the support member 826. The support member 826 accommodates the closing member 822 and the pushing member 824 inside. The support member 826 and the switching unit main body 812 may be formed by integral molding.

  The lid member 828 supports the pushing member 824 to be rotatable. The lid member 828 may be disposed so as to surround the pushing member 824. At least a part of the switching lever 142 may be disposed outside the lid member 828.

  Next, the operation of the switching unit 240 will be described. Since the protruding portion 846 protrudes from the outer periphery of the rotating portion 844, the distance between the outer surface of the pushing member 824 and the opening 836 changes when the user operates the switching lever 142. Therefore, when the user operates the switching lever 142 so that the spike 130 protrudes from the sole 120, the pushing member 824 pushes the closing member 822 into the opening 836 and closes the opening 836. Further, the closing member 822 is prevented from being pushed out from the opening 836 even if the pressure of the working fluid inside the flow path 830 increases.

  On the other hand, when the user operates the switching lever 142 to accommodate the spike 130 in the sole 120, the force with which the pushing member 824 pushes the closing member 822 into the opening 836 is weakened, or the pushing member 824 moves away from the closing member 822. In this state, when the pressure of the working fluid inside the flow path 830 is larger than a certain value, the closing member 822 is pushed out from the opening 836. As a result, the working fluid inside the flow path 830 is discharged to the outside of the spike adjustment mechanism 140 through the opening 836 and the opening 242.
