[0031] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0032] Figure 1 and Figure 2 The figure shows a footrest 100 in an embodiment of the present invention, which includes a fixed seat 101, a first guide member 105, a second guide member 107 and a pedal 102. The fixed seat 101 is provided with at least one slide slot unit, and a slide slot unit includes a first slide slot 106 and a second slide slot 108. The first slide slot 106 and the second slide slot 108 are not collinear. The collinearity of the first slide slot 106 and the second slide slot 108 means that the first slide slot 106 and the second slide slot 108 are both straight, and the center line of the first slide slot 106 ( Figure 3 The first center line 305 in the middle and the center line of the second chute 108 ( Figure 3 306 in the first slide groove 106). On the contrary, the first slide groove 106 and the second slide groove 108 are not collinear, which means that the two slide grooves do not meet the above conditions. The first slide groove 106 and the second slide groove 108 are not collinear, including but not limited to the following situations: (1) the first slide groove 106 and the second slide groove 108 are both straight, but the angle between the first center line 305 and the second center line 306 is an acute angle, a right angle or an obtuse angle; (2) the first slide groove 106 and the second slide groove 108 are both straight, but the first center line 305 and the second center line 306 are parallel; (3) the first slide groove 106 and the second slide groove 108 are both arc-shaped. A first guide member 105 is provided in each first slide groove 106, and a second guide member 107 is provided in each second slide groove 108. A slide groove unit is provided on at least one side of the pedal 102. The first guide member 105 and the second guide member 107 are both connected to the pedal 102. For example, the first guide member 105 and the second guide member 107 are connected at the edge of the pedal 102. The pedal 102 is used to contact with the user's feet and support the user's feet. Figure 3As shown, the pedal 102 can move relative to the fixed seat 101 to change the inclination angle of the pedal 102 relative to the horizontal plane. During the movement of the pedal 102 relative to the fixed seat 101, the first guide member 105 slides along the first slide groove 106, and the second guide member 107 slides along the second slide groove 108. Figure 3 As shown, in this embodiment, the first chute 106 and the second chute 108 are spaced apart from each other and are not connected. However, in other embodiments, the first chute 106 and the second chute 108 may also be directly or indirectly connected, in which case the first chute 106 and the second chute 108 are equivalent to different slot sections in one chute.

[0033] The user's toes can be placed on the front of the pedal 102, and the user's heels can be placed on the rear of the pedal 102. When the pedal 102 is at its maximum tilt angle relative to the horizontal plane, the footstool 100 is suitable for relaxing the user's Achilles tendon and posterior calf muscles. When the pedal 102 is at its minimum tilt angle relative to the horizontal plane, the pedal 102 is close to a horizontal state, and the footstool 100 is suitable for relaxing the user's instep. When the user steps on the pedal 102, the angle and height of the pedal (referring to the height of the bottom end of the pedal 102) can be adaptively changed as the posture of the user's foot changes. Since the pedal 102 cooperates with the slide unit through two guide members, the pedal 102 can move relative to the fixed seat 101 to change the angle and height of the pedal 102. The footstool 100 can provide support for different users, and the adjustment method of the pedal 102 is simple and easy to use. Furthermore, since at least one side of the pedal 102 is provided with two guide members, the pedal 102 is subject to more guide constraints when moving, the structural reliability of the footrest 100 is higher, and the stability of the pedal 102 when moving is better.

[0034] In order to further improve the movement stability of the pedal, the fixing seat 101 may include two slide slot units, which are respectively located on both sides of the pedal. Accordingly, the footrest 100 includes two first guide members 105 and two second guide members 107. Figure 2As shown, the fixing seat 101 includes two side plates 104 and two crossbeams 103. The two side plates 104 are arranged at intervals so as to form a storage space between the two side plates 104. The two side plates 104 are respectively connected to the two ends of the crossbeam 103. The pedal 102 is located in the storage space, that is, the pedal 102 is located between the two side plates 104. Each side plate 104 is provided with a slide groove unit, that is, each side plate 104 is provided with a first slide groove 106 and a second slide groove 108. The crossbeam 103 is also located between the two side plates 104, and the two ends of the crossbeam 103 are respectively connected to the two side plates 104. Specifically, the side plates 104 are further provided with a plug-in hole 109, and the two ends of the crossbeam 103 are inserted into the plug-in hole 109, and the crossbeam 103 and the side plates 104 are fixed to each other. In this embodiment, two crossbeams 103 are provided to improve the structural stability of the fixing seat 101. In other embodiments, the number of crossbeams 103 can also be appropriately increased or decreased. If the fixing base 101 only includes one sliding slot unit, the sliding slot unit is disposed on one of the side plates 104 .

[0035] The first guide member 105 can be configured as a shaft, a pin, a screw, a bolt, etc. In the case where the first guide member 105 is configured as a screw or a bolt, a threaded hole is provided at the edge of the pedal 102, and the first guide member 105 is inserted into the threaded hole, thereby achieving the fixation between the first guide member 105 and the pedal 102. The diameter of the nut of the first guide member 105 is greater than the width of the first slide groove 106, and the nut of the first guide member 105 and the pedal 102 are respectively located on different sides of the side plate 104. Similarly, the second guide member 107 can also be configured as a shaft, a pin, a screw or a bolt.

[0036] In some embodiments, when the pedal 102 moves relative to the fixed seat 101, the first guide member 105 and the second guide member 107 are both fixed relative to the pedal 102 (for example, when the first guide member 105 and the second guide member 107 are both set as screws). The portion of the first guide member 105 disposed in the first slide groove 106 is cylindrical, and during the sliding process of the first guide member 105 along the first slide groove 106, the first guide member 105 can also rotate relative to the side plate 104, thereby reducing the resistance of the first guide member 105 when sliding along the first slide groove 106, and improving the smoothness of the movement of the pedal 102. Similarly, the portion of the second guide member 107 disposed in the second slide groove 108 can also be cylindrical, and during the sliding process of the second guide member 107 along the second slide groove 108, the second guide member 107 can also rotate relative to the second slide groove 108, thereby reducing the resistance of the second guide member 107 when sliding along the second slide groove 108, and improving the smoothness of the movement of the pedal 102. More specifically, when the first guide member 105 and the second guide member 107 are screws, the screw rod of the screw includes a threaded section and a polished section, the outer circumference of the threaded section is provided with threads, and the outer circumference of the polished section is not provided with threads. The threaded section is used to connect with the threaded hole of the pedal 102, and the cylindrical polished section is located in the first slide groove 106 or the second slide groove 108.

[0037] It should be noted that the first guide member 105 and the second guide member 107 do not necessarily need to be fixed to the pedal 102. In other embodiments, the first guide member 105 and the second guide member 107 can be configured as rollers that can rotate relative to the pedal 102. In this configuration, the portion of the first guide member 105 disposed in the first slide groove 106 is cylindrical, and during the sliding process of the first guide member 105 along the first slide groove 106, the first guide member 105 can also rotate relative to the first slide groove 106; the portion of the second guide member 107 disposed in the second slide groove 108 is cylindrical, and during the sliding process of the second guide member 107 along the second slide groove 108, the second guide member 107 can also rotate relative to the second slide groove 108. This configuration is also conducive to improving the smoothness of the pedal 102 during movement.

[0038] The shapes and arrangements of the first slide groove 106 and the second slide groove 108 are introduced below.

[0039] like Figure 3As shown, in the first embodiment, the first slide groove 106 and the second slide groove 108 are arranged at intervals from each other, and the first slide groove 106 and the second slide groove 108 are not connected. In the case where the first slide groove 106 and the second slide groove 108 are arranged at intervals from each other, the first slide groove 106 and the second slide groove 108 can be set as grooves with closed ends, so that the groove wall at the end of the first slide groove 106 can limit the first guide member 105, and the groove wall at the end of the second slide groove 108 can limit the second guide member 107, thereby limiting the movement of the pedal 102. In order to limit the movement of the pedal 102, in other embodiments, the footrest 100 can also be set as: one of the first slide groove 106 and the second slide groove 108 is a groove with closed ends.

[0040] like Figure 3 As shown, in some embodiments, the first slide groove 106 and the second slide groove 108 are both straight grooves. This is conducive to reducing the shape complexity of the first slide groove 106 and the second slide groove 108, thereby reducing the processing difficulty of the fixing seat 101. In order to reduce the shape complexity of the first slide groove 106 and the second slide groove 108, in other embodiments, the first slide groove 106 and the second slide groove 108 can also be set as arc grooves. In addition, in other embodiments, one of the first slide groove 106 and the second slide groove 108 is set as a straight groove, and the other is set as an arc groove, which is also conducive to reducing the shape complexity of the first slide groove 106 and the second slide groove 108.

[0041] like Figure 3 As shown, in some embodiments, at least a portion of the first chute 106 is located above the top of the second chute 108. In the case where the first chute 106 is located in front of the second chute 108, the above arrangement is conducive to increasing the maximum upward inclination angle of the pedal 102. In the case where the first chute 106 is located behind the second chute 108, the above arrangement is conducive to increasing the maximum downward inclination angle of the pedal 102. The arrangement that at least a portion of the first chute 106 is located above the top of the second chute 108 is conducive to increasing the maximum upward inclination angle or downward inclination angle of the pedal 102, so that the user's feet or legs can be fully stretched or stretched. Among them, the upward inclination of the pedal 102 means that the front end of the pedal 102 is located above the rear end of the pedal 102, and the downward inclination of the pedal 102 means that the front end of the pedal 102 is located below the rear end of the pedal 102.

[0042] like Figure 3As shown, in some embodiments, a first slide 106 and a second slide 108 belonging to the same slide unit meet the following conditions: the first slide 106 and the second slide 108 are arranged at intervals in the horizontal direction, the first slide 106 and the second slide 108 are both inclined relative to the horizontal plane, the first slide 106 gradually approaches the second slide 108 in the direction from bottom to top, and the top of the first slide 106 and the top of the second slide 108 are both located between the bottom of the first slide 106 and the bottom of the second slide 108 in the horizontal direction. This setting is convenient for the user to adjust the angle of the pedal 102 with his feet. When the user's heel steps on the rear of the pedal 102 and presses down, the second guide member 107 slides toward the rear and bottom, the first guide member 105 slides toward the rear and top, the rear end of the pedal 102 drops and the front end of the pedal 102 rises, and the upward angle of the pedal 102 increases. The user's toes step on the front part of the pedal 102 and press down, the first guide member 105 slides forward and downward, the second guide member 107 slides forward and upward, the rear end of the pedal 102 rises and causes the front end of the pedal 102 to fall, and the upward angle of the pedal 102 decreases.

[0043] like Figure 2 As shown, in some embodiments, the footrest 100 further includes a locking mechanism 201. After the user has adjusted the angle of the pedal 102, the user can fix the angle of the pedal 102 through the locking mechanism 201. The locking mechanism 201 includes a clamping member 202 and an unlocking member 203, and the clamping member 202 is connected to a first guide member 105. The locking mechanism 201 has a locked state and an unlocked state, and the unlocking member 203 can move relative to the clamping member 202 so that the locking mechanism 201 switches between the above two states. When the locking mechanism 201 is in the locked state, the clamping member 202 and the pedal 102 jointly clamp the fixed seat 101, and the friction force applied by the clamping member 202 and the pedal 102 to the fixed seat 101 hinders the pedal 102 from moving relative to the fixed seat 101. In this state, the angle of the pedal 102 relative to the fixed seat 101 is fixed. More specifically, when the locking mechanism 201 is in the locked state, the clamping member 202 and the pedal 102 jointly clamp the side plate 104 (such as Figure 6 It can also be understood that the clamping member 202 presses the side plate 104 against the edge of the pedal 102. When the locking mechanism 201 is in the unlocked state, the clamping member 202 and the pedal 102 do not clamp the side plate 104 of the fixing seat 101, and the pedal 102 can move relative to the fixing seat 101. In this state, the user can adjust the angle of the pedal 102.

[0044] In other embodiments, the clamping member 202 may also be connected to a second guide member 107, as long as the clamping member 202 and the pedal 102 can clamp the side plate 104 of the fixed seat 101. There may be only one locking mechanism 201, which is installed at one of the first guide members 105 or one of the second guide members 107. In this way, when the pedal 102 needs to be unlocked or locked, the user does not need to operate multiple locking mechanisms 201 in sequence, and the footrest 100 is more convenient to use.

[0045] The following describes how to change the position or state of the clamping member 202 so that the locking mechanism 201 switches between the locked state and the unlocked state.

[0046] like Figure 5 As shown, in some embodiments, the clamping member 202 includes a gasket portion 204 and at least one protrusion 217. The first guide member 105 passes through the gasket portion 204, and the gasket portion 204 includes a second surface 209 and a first surface 208 that are arranged opposite to each other. The first surface is arranged on the side of the gasket portion 204 facing the fixing seat 101, and the protrusion 217 is connected to the second surface 209 and protrudes relative to the second surface 209. The second surface 209 is the right side surface of the gasket portion 204 (as shown in FIG. Figure 4 ), the first surface 208 is the left side surface of the gasket portion 204 (as shown in Figure 5 The locking mechanism 201 further includes an unlocking member 203, which is connected to the first guide member 105 and can move relative to the gasket portion 204. Figure 6 As shown, the first guide member 105 is configured as a screw, and the unlocking member 203 is sleeved on the outside of the nut of the screw. The unlocking member 203 and the first guide member 105 are fixed to each other, and the unlocking member 203 can rotate relative to the clamping member 202. The central axis of the first guide member 105 is also the rotation axis 216 of the unlocking member 203 (as shown in FIG. Figure 4 and Figure 5 As shown in Figure 4 As shown, the unlocking member 203 includes a disc-shaped disc portion 211, the outer surface of the disc portion 211 includes a third surface 210, and the third surface 210 is provided with a receiving groove 212. Figure 4 and Figure 5 It can be seen that the second surface 209 and the third surface 210 are arranged opposite to each other. The second surface 209, the first surface 208 and the third surface 210 can all be arranged as planes.

[0047] Figure 6 1 shows the matching relationship between the clamping member 202, the unlocking member 203, the pedal 102 and the side plate 104 of the fixing seat 101 when the locking mechanism 201 is in the locked state. Figure 6As shown, when the locking mechanism 201 is in the locked state, the protrusion 217 and the receiving groove 212 are staggered, the protrusion 217 is located outside the receiving groove 212, the protrusion 217 is in contact with the third surface 210, and the first surface 208 and the pedal 102 jointly clamp the fixing seat 101 (clamp the side plate 104 of the fixing seat 101). That is, the unlocking member 203 and the clamping member 202 are pressed against each other, so that the clamping member 202 and the side plate 104 are kept pressed against each other.

[0048] Figure 7 1 shows the matching relationship between the clamping member 202, the unlocking member 203, the pedal 102 and the side plate 104 of the fixing seat 101 when the locking mechanism 201 is in the unlocked state. Figure 7 As shown, when the locking mechanism 201 is in the unlocked state, the protrusion 217 is disposed opposite to the receiving groove 212, the protrusion 217 is located in the receiving groove 212, the clamping member 202 can move in the gap 303 between the unlocking member 203 and the fixing seat 101, and the clamping member 202 can move in the gap 303 along the axial direction of the first guide member 105. Since the clamping member 202 is movable, the first surface 208 and the pedal 102 do not clamp the side plate at this time.

[0049] It should be noted that Figure 7 The locking mechanism 201 is in the unlocked state, and the protrusion 217 is accommodated in the receiving groove 212. At this time, there is a gap between the first surface 208 of the clamping member 202 and the side plate 104, and the gap provides a stroke for the clamping member 202 to move axially (left and right) along the first guide member 105. When the locking mechanism 201 switches from the unlocked state to the locked state, the clamping member 202 and the unlocking member 203 rotate relative to each other, so that the protrusion 217 gradually withdraws from the receiving groove 212, and the clamping member 202 is pushed toward the side plate 104. When the protrusion 217 completely withdraws from the receiving groove 212 (that is, the protrusion 217 is located outside the receiving groove 212), the clamping member 202 presses against the side plate 104, that is, the clamping member 202 and the pedal 102 clamp the side plate 104, thereby maintaining the pedal 102 at the current position / angle.

[0050] Based on the structure of the locking mechanism 201 described above, the user can drive the unlocking member 203 to rotate, thereby changing the relative positions of the receiving groove 212 and the protruding portion 217 , thereby switching the state of the locking mechanism 201 .

[0051] In other embodiments, the positions of the protrusion 217 and the receiving groove 212 can be interchanged. For example, in other embodiments, the second surface 209 is provided with the receiving groove 212, and the third surface 210 is provided with the protrusion 217. When the locking mechanism 201 is in the locked state and the unlocked state, the matching relationship between the clamping member 202, the unlocking member 203, the pedal 102 and the side plate 104 of the fixing seat 101 is the same as the above-mentioned embodiment, and is not repeated here.

[0052] Please combine Figure 4 and Figure 5 In some embodiments, the clamping member 202 further includes a restraining portion 205, which is connected to the first surface 208 and protrudes relative to the first surface 208. The restraining portion 205 is slidably disposed in the first slide groove 106, and the restraining portion 205 abuts against the groove wall of the first slide groove 106, thereby preventing the clamping member 202 from rotating relative to the fixing seat 101. The clamping member 202 can slide synchronously with the first guide member 105, and the sliding matching relationship between the restraining portion 205 and the first slide groove 106 guides the sliding of the clamping member 202. In addition, since the restraining portion 205 prevents the clamping member 202 from rotating relative to the fixing seat 101, the clamping member 202 will not rotate with the unlocking member 203 when the unlocking member 203 rotates, and the relative position relationship between the receiving groove 212 and the protruding portion 217 can be changed by the rotation of the unlocking member 203. It should be noted that, in other embodiments, if the locking mechanism 201 is installed at the second guide member 107 , the restraining portion 205 is disposed in the second sliding groove 108 , and the clamping member 202 can slide synchronously with the second guide member 107 .

[0053] like Figure 5 As shown, in some embodiments, the constraint portion 205 may include a first flat plate 206 and a second flat plate 207 that are relatively fixed and parallel to each other, the groove wall of the first slide groove 106 includes a first wall surface 301 and a second wall surface 302 that are arranged opposite to each other and parallel to each other, the first wall surface 301 and the second wall surface 302 are both planes, the first flat plate 206 abuts against the first wall surface 301, and the second flat plate 207 abuts against the second wall surface 302. More specifically, a side surface of the first flat plate 206 facing away from the second flat plate 207 is used to abut against the first wall surface 301, and a side surface of the second flat plate 207 facing away from the first flat plate 206 abuts against the second wall surface 302. The constraint portion 205 composed of the first flat plate 206 and the second flat plate 207 is easy to process and saves materials. In other embodiments, the constraint portion 205 can also be set to other shapes, for example, the constraint portion 205 is set to a quadrangular prism or a hexagonal prism.

[0054] As described above, the unlocking member 203 can rotate relative to the gasket portion 204, so that the protrusion 217 enters and exits the receiving groove 212. Figure 5As shown, the unlocking member 203 further includes a fourth surface 218 and a treading portion 213, and the fourth surface 218 and the third surface 210 are arranged back to back (back to back). The treading portion 213 is arranged on the fourth surface 218 so that the user's foot contacts the treading portion 213. The two ends of the treading portion 213 are respectively located on both sides of the rotation axis 216 of the unlocking member 203. The user's foot can be stepped on the treading portion 213, and the user can step on the treading portion 213 with his foot, thereby switching the state of the locking mechanism 201. In this way, the user does not need to bend over and use his hands to operate the unlocking member 203, and the operation of switching the state of the locking mechanism 201 is more convenient. Since the two ends of the treading portion 213 are respectively located on both sides of the rotation axis 216 of the unlocking member 203, the user can rotate the unlocking member 203 in different directions by stepping on different positions of the unlocking member 203, thereby switching the locking mechanism 201 to different states. More specifically, the two ends of the tread portion 213 are respectively an unlocking end 215 and a locking end 214, wherein the unlocking end 215 is the front end of the tread portion 213, and the locking end 214 is the rear end of the tread portion 213. The user steps down on the unlocking end 215 until the protrusion 217 leaves the receiving groove 212, and the locking mechanism 201 can be switched to the locked state. The user steps down on the locking end 214 until the protrusion 217 enters the receiving groove 212, and the locking mechanism 201 can be switched to the unlocked state.

[0055] As described above, a storage space is formed between the two side plates 104, and the pedal 102 is located in the storage space. The pedal portion 213 can be located outside the storage space. This arrangement allows the pedal portion 213 to be located outside the fixed seat 101, which is convenient for the user to step on the pedal portion 213. The user can step on the pedal 102 with the left foot to change the angle of the pedal 102; when the angle of the pedal 102 is adjusted to the angle required by the user, the user can step on the pedal portion 213 with the right foot (the left foot is still placed on the pedal 102), thereby restoring the locking mechanism 201 to the locked state, thereby fixing the angle of the pedal 102.

[0056] like Figure 4 and Figure 5 As shown, in some embodiments, there are multiple receiving grooves 212, multiple protrusions 217, multiple receiving grooves 212 surround the rotation axis 216 of the unlocking member 203, multiple protrusions 217 are distributed around the rotation axis 216, and one protrusion 217 is matched with one receiving groove 212. In this way, when the locking mechanism 201 is in a locked state, multiple protrusions 217 are all in contact with the third surface 210, and the pressure applied by the unlocking member 203 to the clamping member 202 is more uniformly distributed. The unlocking member 203 can better press the clamping member 202 against the side of the side plate 104, thereby improving the clamping effect of the clamping member 202 and the pedal 102 on the side plate 104.

[0057] It should be noted that, in other embodiments, the movement mode of the unlocking member 203 relative to the gasket portion 204 can also be set to move (move along a straight line), as long as the relative positions of the receiving groove 212 and the protrusion 217 can be changed when the unlocking member 203 moves. In addition, the unlocking mechanism does not necessarily require the unlocking member 203. For example, the locking mechanism 201 can only include the clamping member 202, the first guide member 105 passes through the clamping member 202, the clamping member 202 is threadedly connected to the first guide member 105, and the clamping member 202 is equivalent to a nut. The user can adjust the position of the clamping member 202 by rotating the clamping member 202, so that the clamping member 202 is pressed against the side plate 104 or the contact between the clamping member 202 and the side plate 104 is released, thereby switching the state of the locking mechanism 201.
