Technical Field

[0001] This utility model relates to the field of training equipment, and in particular to a movable joint for a seated pedal trainer and a seated pedal trainer. Background Technology

[0002] A seated pedal trainer is a fitness device that allows users to sit in a chair and swing their hands and / or feet back and forth on the swing arms of the trainer to exercise their arms and / or legs.

[0003] However, current seated pedal trainers, as home fitness equipment, only offer one mode: back-and-forth swinging. Their limited functionality fails to meet users' needs. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a movable joint for a seated pedal trainer, which allows the rocker arm to swing back and forth and left and right relative to the support column, enabling more usage modes to meet different user needs. This utility model also provides a seated pedal trainer.

[0005] To achieve the above objectives, the present invention employs the following technical solution:

[0006] A movable joint for a seated pedal trainer, used to connect a rocker arm to a support column, includes:

[0007] A support column connector, the support column connector being used to connect to the support column;

[0008] A rocker arm connector for connecting to the rocker arm;

[0009] And an intermediate swing member, which is rotatably connected to the support column connector and the rocker arm connector respectively, and the rotation axis of the rocker arm connector relative to the intermediate swing member is perpendicular to the rotation axis of the intermediate swing member relative to the support column connector.

[0010] By adopting the above technical solution, since the rocker arm connector can rotate relative to the intermediate swing member, the intermediate swing member can rotate relative to the support column connector, and the rotation axis of the rocker arm connector relative to the intermediate swing member is perpendicular to the rotation axis of the intermediate swing member relative to the support column connector, the rocker arm connector can move back and forth, left and right, and in combination relative to the support column connector, that is, the rocker arm installed on the rocker arm connector can move relative to the support column in the back and forth, left and right, and in combination directions.

[0011] The above technical solution allows users to use the seated training device in more ways. For example, when the rocker arm connector is equipped with an upper swing arm, the user can sit on a chair and hold the upper swing arm's grip to swing back and forth for arm swing training. The user can also swing left and right to train the arms and chest expansion exercises. Of course, the user can also perform a combination of forward and backward and left and right movements, that is, swinging back and forth while swinging left and right, presenting an arc-shaped movement to achieve a rowing-like training.

[0012] When the rocker arm connector is equipped with a lower swing arm, the user can sit on a chair and then step on the foot of the lower swing arm to swing back and forth for seated stepping training. They can also swing left and right to train their legs and related joints. Of course, they can also perform a combination of forward and backward and left and right movements, that is, swinging back and forth while swinging left and right, presenting an arc-shaped movement, which can better train the legs.

[0013] When the rocker arm connector is equipped with both an upper swing arm and a lower swing arm, the upper and lower swing arms on the same rocker arm connector move in opposite directions. That is, when the upper swing arm moves forward, the lower swing arm moves backward; when the upper swing arm moves backward, the lower swing arm moves forward; when the upper swing arm moves to the left, the lower swing arm moves to the right; and when the upper swing arm moves to the right, the lower swing arm moves to the left. This allows the user to train both arms and legs simultaneously.

[0014] Furthermore, the support column connector is configured as a movable joint pivot, and the intermediate swing member is configured as a connecting sleeve. The intermediate swing member is sleeved outside the support column connector and can rotate about the support column as the axis of rotation; or the support column connector is configured as a connecting sleeve, and the intermediate swing member is configured as a movable joint pivot. The intermediate swing member is inserted into the support column connector and can rotate about the axis of rotation of the intermediate swing member.

[0015] By adopting the above technical solution, the support column connector and the intermediate swing member are more reasonable, and the installation between the support column connector and the intermediate swing member is easier in actual production. It also facilitates the rotational movement of the intermediate swing member relative to the support column connector after installation.

[0016] Furthermore, the side wall of the intermediate swing member is provided with a first connecting rotating part, and the rocker arm connector is provided with a second connecting rotating part that matches the first connecting rotating part, and the rocker arm connector is rotatably connected to the first connecting rotating part through the second connecting rotating part.

The connecting shaft part extends along a direction perpendicular to the rotation axis of the intermediate swing member relative to the support column connector, and the axis of the connecting shaft hole is consistent with the direction perpendicular to the rotation axis of the intermediate swing member relative to the support column connector.

[0018] By adopting the above technical solution, the intermediate swing component and the rocker arm connector are more reasonable, and the installation between the intermediate swing component and the rocker arm connector is convenient in actual production. It also facilitates the rotational movement of the rocker arm connector and the intermediate swing component after installation.

[0019] Furthermore, the first connecting rotating part is configured as the connecting rotating shaft part, and correspondingly, the second connecting rotating part is configured as the connecting rotating shaft hole;

[0020] The intermediate swing member includes an intermediate swing member body and a connecting shaft. The intermediate swing member body is rotatably connected to the support column connector. The connecting shaft passes through the intermediate swing member body along a rotation axis perpendicular to the rotation axis of the intermediate swing member relative to the support column connector, and at least one end of the connecting shaft protrudes from the outer wall of the intermediate swing member body to form the connecting shaft portion.

[0021] By adopting the above technical solution, the intermediate swing component is made more reasonable, which facilitates actual production and installation. Specifically, the body of the intermediate swing component can be first installed on the support column connector; then the rocker arm connector can be pre-installed on the intermediate swing component so that the connecting shaft hole on the rocker arm connector is aligned with the intermediate swing component for installing the connecting shaft; then the connecting shaft passes through the connecting shaft hole and is inserted into the body of the intermediate swing component; preferably, both ends of the connecting shaft protrude from the outer wall of the body of the intermediate swing component to form the connecting shaft portion.

[0022] Furthermore, the inner diameter of the connecting sleeve is larger than the diameter of the movable joint shaft, and a first joint bearing is provided between the connecting sleeve and the movable joint shaft. The diameter of the movable joint shaft matches the inner ring inner hole of the first joint bearing so as to be inserted into the inner ring inner hole of the first joint bearing, and the inner diameter of the connecting sleeve matches the outer ring outer diameter of the first joint bearing so as to be sleeved on the outside of the first joint bearing.

[0023] The diameter of the connecting shaft hole is larger than the diameter of the connecting shaft part. A second spherical bearing is provided between the connecting shaft hole and the connecting shaft part. The diameter of the connecting shaft part matches the inner ring inner hole of the second spherical bearing so as to be inserted into the inner ring inner hole of the second spherical bearing. The diameter of the connecting shaft hole matches the outer ring outer diameter of the second spherical bearing so as to be sleeved on the outside of the second spherical bearing.

[0024] By adopting the above technical solution, the movable joint is made more reasonable, the movement of the connecting sleeve relative to the movable joint pivot is smoother, and the movement of the connecting pivot hole relative to the connecting pivot part is smoother; thus, the movement of the intermediate swing member relative to the support column connector is smoother, and the movement of the rocker arm connector relative to the intermediate swing member is smoother.

[0025] Furthermore, multiple first joint bearings are provided, and the multiple first joint bearings are spaced apart in the axial direction extending from the movable joint shaft.

[0026] By adopting the above technical solution, the installation between the support column connector and the intermediate swing member is more reasonable, and the arrangement of multiple first joint bearings enables the movement of the intermediate swing member relative to the support column connector to be smoother; preferably, two first joint bearings are provided.

[0027] Furthermore, the rocker arm connector is provided with a swing hole, and the rocker arm connector is sleeved on the outside of the intermediate swing member through the swing hole. The rocker arm connector has a second connecting rotating part at the corresponding position of the swing hole on both side walls in the direction of its rotation axis. When the second connecting rotating part is configured to connect to the pivot hole, the pivot hole is connected to the swing hole. When the second connecting rotating part is configured to connect to the pivot part, the pivot part extends toward the swing hole.

[0028] By adopting the above technical solution, the rocker arm connector is made more reasonable, which facilitates the installation of the rocker arm connector onto the intermediate swing member; and when the rocker arm connector is installed onto the intermediate swing member, the second connecting rotating part on both sides of the swing hole of the rocker arm connector can cooperate with the first connecting rotating part on both sides of the intermediate swing member, which makes the rotational connection between the rocker arm connector and the intermediate swing member more stable and reliable.

[0029] When the rocker arm connector is sleeved outside the intermediate swing member through the swing hole, it can also control the movement of the rocker arm connector in the direction perpendicular to its rotation axis, and also ensure the stability of the installation of the rocker arm connector and the intermediate swing member.

[0030] Furthermore, the intermediate swing member is restricted to move relative to the support column connector along its axis.

[0031] By adopting the above technical solution, the movable joint becomes more reasonable and its operation more reliable and stable.

[0032] Furthermore, the connecting shaft is restricted to movement in its axial direction and to movement perpendicular to its axial direction.

[0033] By adopting the above technical solution, the movable joint is made more reasonable, more reliable and stable in operation, and since the connecting shaft is set through the intermediate swing member body, the movement of the intermediate swing member body in the direction perpendicular to the connecting shaft axis can also be restricted, that is, the movement of the intermediate swing member body in the axis of the support column connector is restricted.

[0034] Furthermore, the movable joint includes a connecting pivot limiting member, the support column connector is configured as the movable joint pivot, and correspondingly, the intermediate swing member body is configured as a connecting sleeve. The connecting pivot is disposed on the outside of the support column connector and has a connecting pivot through hole at a corresponding position on the support column connector. The connecting pivot through hole is disposed along the axis perpendicular to the connecting pivot. One end of the connecting pivot limiting member is provided with a limiting member limiting cap with a diameter larger than the connecting pivot through hole, and the other end is formed as a limiting member fixing end. The limiting member fixing end of the connecting pivot limiting member passes through the connecting pivot through hole and is connected to the support column connector.

[0035] By adopting the above technical solution, the connecting shaft limiting member and the connecting shaft through hole are engaged, and the limiting member limiting cap restricts the connecting shaft, which can restrict the connecting shaft to move in its axial direction and to move in a direction perpendicular to its axial direction.

[0036] Furthermore, a pad is provided between the support column connector and the connecting shaft, and the two sides of the pad abut against the support column connector and the connecting shaft respectively.

[0037] By adopting the above technical solution, the movable joint is made more reasonable; the pad block can make the movable joint more stable as a whole, and can prevent the shaking between the parts in the movable joint. Therefore, the operation of the movable joint is more reliable, stable and quiet.

[0038] Furthermore, the pad is recessed on the side facing the connecting shaft, and a pad groove matching the connecting shaft is provided.

[0039] By adopting the above technical solution, the contact between the pad and the connecting shaft becomes more stable.

[0040] A seated pedaling training device includes a support column, a rocker arm, and a movable joint. The rocker arm is disposed on the side of the support column via the movable joint, and the rocker arm can swing back and forth and left and right relative to the support column via the movable joint. The rocker arm includes an upper rocker arm disposed above the movable joint and / or a lower rocker arm disposed below the movable joint. The end of the upper rocker arm away from the movable joint is provided with a gripping part for hand holding, and the end of the lower rocker arm away from the movable joint is provided with a pedaling part for foot pedaling.

[0041] By adopting the above technical solution, since the rocker arm can swing back and forth and left and right relative to the support column through the movable joint, that is, the rocker arm can swing back and forth, swing left and right, and perform compound swings; therefore, the seated training device can realize more usage scenarios to meet the different usage scenarios of users.

[0042] Specifically, when the rocker arm only includes the upper rocker arm, the user can sit on a chair and hold the grip part of the upper rocker arm to swing back and forth for arm swing training, or swing left and right to train the arms and chest expansion exercises. Of course, a combination of forward and backward and left and right movements can also be performed, that is, swinging back and forth while swinging left and right, presenting an arc-shaped movement to achieve a rowing-like training.

[0043] When the rocker arm only includes the lower rocker arm, the user can sit on a chair and then step on the footrest of the lower rocker arm to swing back and forth for seated stepping training. They can also swing left and right to train their legs and related joints. Of course, they can also perform a combination of forward and backward and left and right movements, that is, swinging back and forth while swinging left and right, presenting an arc-shaped movement, which can better train the legs.

[0044] When the rocker arm includes the upper rocker arm and the lower rocker arm, the upper rocker arm and the lower rocker arm, which are mounted on the same rocker arm connector, move in opposite directions. That is, when the upper rocker arm moves forward, the lower rocker arm moves backward; when the upper rocker arm moves backward, the lower rocker arm moves forward; when the upper rocker arm moves to the left, the lower rocker arm moves to the right; and when the upper rocker arm moves to the right, the lower rocker arm moves to the left. This allows the user to train both arms and legs simultaneously.

[0045] Furthermore, the movable joint adopts the movable joint for the seated pedal trainer described above. In the movable joint, the rotation axis of the intermediate swing member relative to the support column connector is arranged along the front-back direction, and the rotation axis of the rocker arm connector relative to the intermediate swing member is arranged along the left-right direction. The upper rocker arm is arranged above the rocker arm connector, and the lower rocker arm is arranged below the rocker arm connector.

[0047] Furthermore, the rocker arm is provided in two sets, and correspondingly, the movable joint is provided in two sets. The two sets of rocker arms are respectively provided on opposite sides of the support column through the two movable joints.

[0048] By adopting the above technical solution, the seated training device becomes more reasonable, and the setting of the two sets of rocker arms can train both hands and feet simultaneously.

[0049] Furthermore, the upper rocker arm is detachably connected to the movable joint.

[0050] By adopting the above technical solution, when the user is not using the device, the upper rocker arm can be detached from the movable joint for easy storage, reducing the space required for storage; when the device is needed, the upper rocker arm can be installed back onto the movable joint.

[0051] Furthermore, the support column has a storage cavity along its height direction, and the top of the support column is provided with an upper opening communicating with the storage cavity, through which the upper rocker arm can be inserted into the storage cavity.

[0052] By adopting the above technical solution, the seat pedal trainer becomes more reasonable. When the user does not need to use it, the user can insert the disassembled upper rocker arm into the storage cavity; when the user needs to use it, the user can take the upper rocker arm out of the storage cavity and then install it on the movable joint. The above technical solution allows the seat pedal trainer to occupy less space when stored, making it easier to store; and it can also prevent the disassembled upper rocker arm from being lost.

[0053] Furthermore, the upper end of the movable joint is provided with a first disassembly and assembly structure, and correspondingly, the end of the upper rocker arm used to connect with the movable joint is provided with a second disassembly and assembly structure, and the first disassembly and assembly structure and the second disassembly and assembly structure can be disassembled and assembled together.

[0054] Specifically, one of the first and second disassembly structures is configured as a disassembly post, and the other of the first and second disassembly structures is configured as a disassembly groove that can be inserted and engaged with the disassembly post.

[0055] The above technical solution facilitates the disassembly and installation of the upper rocker arm and the movable joint.

[0056] Furthermore, the gripping part is rotatably disposed between the gripping part and the upper rocker arm, and the axis of rotation of the gripping part relative to the upper rocker arm extends along the front-back direction.

[0057] By adopting the above technical solution, the grip can rotate inward and outward relative to the upper rocker arm in the left and right directions, so that it can be adjusted according to the user's usage and better meet the actual usage needs; for example, the grip can be rotated to a vertical position, an inward or outward horizontal position, or an inward or outward 45-degree angle, etc.

[0058] Furthermore, the foot pedal is rotatably configured with respect to the lower rocker arm, and the axis of rotation of the foot pedal relative to the lower rocker arm extends in the left-right direction.

Preferably, two first joint bearings 8 are provided.

[0100] Furthermore, the rocker arm connector 2 is provided with a swing hole 202. The rocker arm connector 2 is sleeved on the outside of the intermediate swing member 3 through the swing hole 202. The rocker arm connector 2 has a second connecting rotating part 201 on both side walls in the direction of its rotation axis at the corresponding positions of the swing hole 202. When the second connecting rotating part 201 is configured to connect to the shaft hole 7, the shaft hole 7 is connected to the swing hole 202. When the second connecting rotating part 201 is configured to connect to the shaft part 6, the shaft part 6 extends toward the swing hole 202.

[0101] By adopting the above technical solution, the rocker arm connector 2 is made more reasonable, making it easier to install the rocker arm connector 2 onto the intermediate swing member 3; and when the rocker arm connector 2 is installed onto the intermediate swing member 3, the second connecting rotating part 201 on both sides of the swing hole 202 of the rocker arm connector 2 can cooperate with the first connecting rotating part 301 on both sides of the intermediate swing member 3, making the rotational connection between the rocker arm connector 2 and the intermediate swing member 3 more stable and reliable;

[0102] When the rocker arm connector 2 is sleeved on the outside of the intermediate swing member 3 through the swing hole 202, it can also control the movement of the rocker arm connector 2 in the direction perpendicular to its rotation axis, and also ensure the stability of the installation of the rocker arm connector 2 and the intermediate swing member 3.

[0103] Furthermore, the intermediate swing member 3 is restricted to move relative to the support column connector 1 along its axis.

[0104] By adopting the above technical solution, the movable joint 300 becomes more reasonable, and its operation becomes more reliable and stable.

[0105] Furthermore, the connecting shaft 303 is restricted to movement in its axial direction and to movement perpendicular to its axial direction.

[0106] By adopting the above technical solution, the movable joint 300 is more reasonable, more reliable and stable in operation, and since the connecting shaft 303 is set through the intermediate swing member body 302, it can also restrict the movement of the intermediate swing member body 302 in the axial direction perpendicular to the connecting shaft 303, that is, it can restrict the movement of the intermediate swing member body 302 on the axis of the support column connector 1.

[0107] Further, the movable joint 300 includes a connecting pivot restrictor 10, the support column connector 1 is configured as a movable joint pivot 4, and correspondingly, the intermediate swing body 302 is configured as a connecting sleeve 5. The connecting pivot 303 is disposed on the outside of the support column connector 1 and has a connecting pivot through hole 303-1 at a corresponding position on the support column connector 1. The connecting pivot through hole 303-1 is disposed along the axis perpendicular to the connecting pivot 303. One end of the connecting pivot restrictor 10 is provided with a restrictor restrictor cap 1001 with a diameter larger than the connecting pivot through hole 303-1, and the other end is formed as a restrictor fixing end 1002. The restrictor fixing end 1002 of the connecting pivot restrictor 10 passes through the connecting pivot through hole 303-1 and is connected to the support column connector 1.

[0108] By adopting the above technical solution, the connection shaft limiting member 10 cooperates with the connection shaft through hole 303-1, and the limiting member limiting cap 1001 restricts the connection shaft 303, which can restrict the movement of the connection shaft 303 in its axial direction and in a direction perpendicular to its axial direction.

[0109] Furthermore, a pad 11 is provided between the support column connector 1 and the connecting shaft 303, and the two sides of the pad 11 abut against the support column connector 1 and the connecting shaft 303 respectively.

[0110] By adopting the above technical solution, the movable joint 300 is made more reasonable; the pad 11 makes the movable joint 300 more stable as a whole, and can prevent the shaking between the parts in the movable joint 300. Therefore, the operation of the movable joint 300 is more reliable, stable and quiet.

[0111] Furthermore, the pad 11 is recessed on the side facing the connecting shaft 303 and has a pad groove 1101 that matches the connecting shaft 303.

[0112] By adopting the above technical solution, the contact between the pad 11 and the connecting shaft 303 becomes more stable.

[0113] See Figures 1 to 5A seated pedaling training device includes a support column 100, a rocker arm 200, and a movable joint 300. The rocker arm 200 is disposed on the side of the support column 100 via the movable joint 300, and the rocker arm 200 can swing back and forth and left and right relative to the support column 100 via the movable joint 300. The rocker arm 200 includes an upper rocker arm 200-1 disposed above the movable joint 300 and / or a lower rocker arm 200-2 disposed below the movable joint 300.

[0114] By adopting the above technical solution, since the rocker arm 200 can swing back and forth and left and right relative to the support column 100 through the movable joint 300, that is, the rocker arm 200 can swing back and forth, swing left and right, and perform compound swings; therefore, the seated training device can realize more usage scenarios to meet the different usage scenarios of users.

[0115] Specifically, when the rocker arm 200 only includes the upper rocker arm 200-1, the user can sit on a chair and hold the grip part 400 of the upper rocker arm to swing back and forth for arm swing training. The user can also swing left and right to train the arms and chest expansion exercises. Of course, the user can also perform a combination of forward and backward and left and right movements, that is, swinging back and forth while swinging left and right, presenting an arc-shaped movement to achieve a rowing-like training.

[0116] When the rocker arm 200 only includes the lower rocker arm 200-2, the user can sit on a chair and then step on the foot pedal part 500 of the lower rocker arm to swing back and forth for seated stepping training. The user can also swing left and right to train the legs and related joints. Of course, the user can also perform a combination of forward and backward and left and right movements, that is, swinging back and forth while swinging left and right, presenting an arc-shaped movement, which can better train the legs.

[0117] When the rocker arm 200 includes the upper rocker arm 200-1 and the lower rocker arm 200-2, the upper and lower rocker arms, which are mounted on the same rocker arm connector 2, move in opposite directions. That is, when the upper rocker arm moves forward, the lower rocker arm moves backward; when the upper rocker arm moves backward, the lower rocker arm moves forward; when the upper rocker arm moves to the left, the lower rocker arm moves to the right; and when the upper rocker arm moves to the right, the lower rocker arm moves to the left. This allows the user to train both arms and legs simultaneously.

[0118] Furthermore, the movable joint 300 adopts the movable joint 300 for the seated pedal trainer described above. In the movable joint 300, the rotation axis of the intermediate swing member 3 relative to the support column connector 1 is arranged along the front-back direction, and the rotation axis of the rocker arm connector 2 relative to the intermediate swing member 3 is arranged along the left-right direction. The upper rocker arm 200-1 is arranged above the rocker arm connector 2, and the lower rocker arm 200-2 is arranged below the rocker arm connector 2.

[0119] By adopting the above technical solution, the setting of the movable joint 300 is made more reasonable.

[0120] Furthermore, the rocker arm 200 is provided in two sets, and correspondingly, the movable joint 300 is provided in two sets. The two sets of rocker arms 200 are respectively provided on opposite sides of the support column 100 through the two movable joints 300.

[0122] Furthermore, the upper rocker arm 200-1 is detachably connected to the movable joint 300.

[0123] By adopting the above technical solution, when the user is not using the device, the upper rocker arm 200-1 can be detached from the movable joint 300 for easy storage, reducing the space required for storage; when the device is needed, the upper rocker arm 200-1 can be installed onto the movable joint 300.

[0124] Furthermore, the support column 100 has a storage cavity 100-1 along its height direction, and the top of the support column 100 is provided with an upper opening 100-2 communicating with the storage cavity 100-1, and the upper rocker arm 200-1 can be inserted into the storage cavity 100-1 through the upper opening 100-2.

[0125] By adopting the above technical solution, the seat pedal trainer becomes more reasonable. When the user does not need to use it, the user can insert the disassembled upper rocker arm 200-1 into the storage cavity 100-1. When the user needs to use it, the user can remove the upper rocker arm 200-1 from the storage cavity 100-1 and then install it on the movable joint 300. The above technical solution allows the seat pedal trainer to occupy less space when stored, making it easier to store. It also prevents the disassembled upper rocker arm 200-1 from being lost.

[0126] Furthermore, the upper end of the movable joint 300 is provided with a first disassembly structure 300-1, and correspondingly, the end of the upper rocker arm 200-1 used to connect with the movable joint 300 is provided with a second disassembly structure 200-11, and the first disassembly structure 300-1 and the second disassembly structure 200-11 can be disassembled and assembled together.

[0127] Specifically, one of the first disassembly structure 300-1 and the second disassembly structure 200-11 is configured as a disassembly post 600, and the other of the first disassembly structure 300-1 and the second disassembly structure 200-11 is configured as a disassembly groove 700 that can be inserted and engaged with the disassembly post 600.

[0128] The above technical solution facilitates the disassembly and installation of the upper rocker arm 200-1 and the movable joint 300.

[0129] See Figure 5 Furthermore, the gripping part 400 is rotatably disposed between the upper rocker arm 200-1, and the axis of rotation of the gripping part 400 relative to the upper rocker arm 200-1 extends along the front-back direction.

[0130] By adopting the above technical solution, the grip 400 can rotate inward and outward relative to the upper rocker arm 200-1 in the left and right directions, so that it can be adjusted according to the user's usage and better meet the actual usage needs; for example, the grip 400 can be rotated to a vertical state, a horizontal state facing inward or outward, or a 45-degree angle facing inward or outward, etc.

[0131] Furthermore, the foot pedal 500 is rotatably configured with respect to the lower rocker arm 200-2, and the axis of rotation of the foot pedal 500 relative to the lower rocker arm 200-2 extends in the left-right direction.

[0132] By adopting the above technical solution, the foot pedal 500 is made more reasonable, and the user can step on the foot pedal 500 very stably when the swing arm swings.
