Description

Technical Field

[0001] This application belongs to the field of fitness equipment technology, and in particular relates to a trigger switch and a training device equipped with the trigger switch. Background Technology

[0002] In outdoor fitness products, product safety is an important factor to consider.

[0003] In the existing technology, the counterweight of outdoor trainers is usually enclosed in the casing. When adjusting the counterweight, the user usually puts an adjustment handle into the trainer to adjust the resistance or switch the training mode.

[0004] However, once the adjustment handle is inserted into the trainer, it remains in a state where it can be used to adjust the trainer. If the user accidentally touches the adjustment handle during training, a safety accident may easily occur. Checking the status of the adjustment handle before each training session is a waste of time and affects the user experience. Utility Model Content

[0005] To address the shortcomings of related technologies, this application provides a trigger switch and a trainer equipped with it. By cooperating with a limiting member and a blocking member, the blocking member abuts against or avoids the end of the handle, thereby blocking or allowing the handle to connect to the counterweight mechanism for counterweight selection. This avoids accidental touch of the handle, which would cause it to directly connect to the counterweight mechanism for counterweight selection, thereby reducing the probability of safety accidents and saving inspection time.

[0006] On one hand, this application provides a trigger switch, which is disposed between the handle of the trainer and the counterweight mechanism inside the trainer housing, the trigger switch comprising:

[0007] A mounting base is provided on the housing of the trainer, and the handle is inserted through the mounting base;

[0008] A limiting element is provided on the mounting base;

[0009] A blocking element is provided on the limiting element;

[0010] In normal conditions, the blocking member abuts against the end of the handle to prevent the handle from connecting to the counterweight mechanism for counterweight selection;

[0011] When using the handle to select the counterweight, the blocking member moves to avoid the end of the handle so that the handle can be connected to the counterweight mechanism for counterweight selection.

[0012] In some embodiments, the blocking member includes:

[0013] A limiting part is slidably disposed on the limiting member, and the limiting part is used to limit the end position of the blocking member when it slides closer to the mounting base;

[0014] A blocking part is provided on one side of the limiting part, and the blocking part is used to prevent the handle from connecting with the counterweight mechanism for counterweight selection;

[0015] An abutment is provided between the blocking part and the limiting part and is connected to both respectively. The abutment is used to avoid the end of the handle so as to allow the handle to be connected to the counterweight mechanism for counterweight selection.

[0016] In some embodiments, the trigger switch further includes:

[0017] A first elastic element is disposed between the mounting base and the blocking element. The first elastic element is used to normally drive the limiting portion away from the mounting base, thereby causing the blocking element to abut against the handle.

[0018] In some embodiments, the blocking member moves toward the mounting base until the limiting portion is at its closest position to the mounting base, at which point the clearance portion aligns with the end of the handle to allow the handle to connect with the counterweight mechanism for counterweight selection.

[0019] In some embodiments, the trigger switch further includes:

[0020] A switch element, one end of which is located on the side of the blocking member away from the mounting base, and the other end is used to press or release the first elastic member, so as to drive the blocking member to slide along the limiting member, thereby abutting or avoiding the end of the handle.

[0021] In some embodiments, there are two limiting members, which are arranged parallel to each other on the mounting base. The blocking member is slidably disposed on the two limiting members, and the two limiting members cooperate to make the blocking member slide stably.

[0022] In some embodiments, the trigger switch further includes:

[0023] A guide is provided on the side of the mounting base away from the blocking member. The guide is open at both ends and hollow inside. One end of the guide is open at the position where the handle is inserted and is fixed on the mounting base. The other end is open to guide the handle to extend in.

[0024] In some embodiments, the trigger switch further includes:

[0025] A second elastic element is disposed between the guide and the handle, and the second elastic element is used to normally drive the handle away from the mounting base.

[0026] In some embodiments, the trigger switch further includes:

[0027] An abutment is provided inside the guide member. The inner diameter of the abutment is larger than the outer diameter of the handle insertion end, and the inner diameter of the abutment is smaller than the outer diameter of the second elastic member. The abutment is used to abut against the second elastic member and keep it stable.

[0028] On the other hand, this application also provides a trainer equipped with a trigger switch as described in any of the above claims to block or allow the handle to be connected to the counterweight mechanism for counterweight selection.

[0029] In summary, this application provides a trigger-type switch and a trainer equipped with it. Through the cooperation of a limiting member and a blocking member, the blocking member abuts against or avoids the end of the handle, thereby blocking or allowing the handle to connect to the counterweight mechanism for counterweight selection. This prevents accidental touches that could directly connect the handle to the counterweight mechanism, thus reducing the probability of safety accidents and saving inspection time. A first elastic member is provided to normally drive the blocking member away from the mounting base, causing the blocking member to abut against the end of the handle, preventing the handle from connecting to the counterweight mechanism. A switching member is provided to maintain or release the blocking member against the first elastic member, thus keeping the blocking member abutting or avoiding the end of the handle. A guide member is provided to guide the handle through the mounting base, avoiding excessive calibration time. A second elastic member is provided to normally drive the handle in a direction away from the mounting base, preventing it from remaining connected to the counterweight mechanism after adjustment, thus affecting the resetting of the blocking member. An abutment boss is provided to ensure stable operation of the second elastic member between the guide member and the handle.

[0040] Reference Appendix Figure 1 , Figure 1 This is a perspective view of the trigger switch of this application; the following is in conjunction with the attached diagram. Figure 1 Specific embodiments are described below.

[0041] Reference Appendix Figure 1This application provides a trigger switch, which is disposed between the handle of the trainer and the counterweight mechanism inside the trainer housing. The trigger switch is used to open or close the adjustment port on the trainer. The trigger switch includes a mounting base 200, a limiting member 300, and a blocking member 400.

[0042] The limiting member 300 is disposed on the mounting base 200, and the blocking member 400 is disposed on the limiting member 300. Under normal conditions, the blocking member 400 abuts against the end of the handle 100 to prevent the handle 100 from connecting with the counterweight mechanism for counterweight selection. When using the handle 100 to select the counterweight, the blocking member 400 moves to avoid the end of the handle 100 so that the handle 100 can connect with the counterweight mechanism for counterweight selection.

[0043] It should be noted that the blocking member 400 is provided on the limiting member 300. The user drives the blocking member 400 to make the blocking member 400 abut against the end of the handle 100, or to make the blocking member 400 avoid the end of the handle 100. The relative movement relationship between the blocking member 400 and the limiting member 300 includes, but is not limited to, relative sliding, relative rotation and relative rolling.

[0044] The trainer includes a housing, a counterweight mechanism, an adjustment port, and a handle 100. The counterweight mechanism is located inside the housing and is used to provide resistance during training. The handle 100 further includes an insertion end and a gripping end. The end of the handle that abuts against the blocking member is the insertion end. The user grasps the gripping end and inserts the insertion end into the adjustment port in a first direction. After the insertion end passes through the adjustment port and connects to the counterweight mechanism inside the trainer, the user can adjust the resistance by rotating the handle 100.

[0045] In some embodiments, the mounting base 200 is disposed on the housing of the trainer, and the housing of the trainer is provided with an adjustment port. The handle 100 passes through the adjustment port along a first direction and is mounted on the mounting base 200. One end of the limiting member 300 is fixed on the mounting base 200, and the other end extends along a second direction away from the mounting base 200. The second direction is perpendicular to the first direction and is slidably disposed on the limiting member 300. The blocking member 400 slides away from the mounting base 200 along the second direction, thereby covering the adjustment port to close it. The blocking member 400 is provided with a clearance portion. The blocking member 400 slides along the second direction closer to the mounting base 200 until the clearance portion is aligned with the adjustment port, thereby opening the adjustment port to allow the handle 100 to pass through.

[0046] Reference Appendix Figure 1 In some embodiments, the mounting base 200 is made of materials including but not limited to aluminum alloy, steel, cast iron, and other metal materials, and the mounting base 200 is fixed to the housing of the trainer. An adjustment port is opened on the side wall of the mounting base 200 to connect the two sides of the mounting base 200.

[0047] The limiting member 300 is a long strip-shaped component. One end of the limiting member 300 is fixed to the top wall of the mounting base 200, and the other end extends along the second direction away from the mounting base 200.

[0048] The limiting member 300 is used to guide the sliding of the blocking member 400 and restrict the sliding direction of the blocking member 400 so that the blocking member 400 slides closer to the mounting base 200 or slides away from the mounting base 200 in the second direction.

[0049] Since the handle 100 passes through the adjustment port in the first direction and the limiting member 300 extends in the second direction, which is perpendicular to the first direction.

[0050] Therefore, based on the limiting and guiding effect of the limiting member 300, the movement trajectory of the blocking member 400 intersects with the movement trajectory of the handle 100, thereby affecting each other's movement.

[0051] Reference Appendix Figure 1 In some other embodiments, there are two limiting members 300, which are arranged in parallel on the mounting base 200. The blocking member 400 is slidably disposed on the two limiting members 300, and the two limiting members 300 cooperate to make the blocking member 400 slide stably.

[0052] Specifically, the two limiting members 300 are fixedly mounted in parallel on the mounting base 200. One end of each limiting member 300 is fixed to the top wall of the mounting base 200, and the other end extends along the second direction away from the mounting base 200.

[0053] The blocking member 400 is slidably disposed on the two limiting members 300. The two limiting members 300 cooperate to prevent the blocking member 400 from shifting laterally during movement and causing jamming, thereby ensuring that the blocking member 400 slides stably along the second direction.

[0054] Reference Appendix Figure 1 In some embodiments, the blocking member 400 is slidably disposed on the limiting member 300, and the blocking member 400 slides away from the mounting base 200 in the second direction, thereby covering the adjustment port to close it; the blocking member 400 is provided with a relief part, and the blocking member 400 slides close to the mounting base 200 in the second direction until the relief part is aligned with the adjustment port, thereby opening the adjustment port to allow the handle 100 to pass through.

[0055] Specifically, the blocking member 400 is slidably disposed on the limiting member 300, and the blocking member 400 is provided with a clearance part, which is used to clearance the end of the handle 100 so as to allow the handle 100 to connect with the counterweight mechanism for counterweight selection.

[0056] When the blocking member 400 slides away from the mounting base 200 in the second direction, the clearance part on the blocking member 400 intersects with the adjustment port on the mounting base 200, and other positions on the blocking member 400 cover and block the adjustment port, thereby closing the adjustment port. At this time, the handle 100 cannot pass through the adjustment port in the first direction to connect with the counterweight mechanism for counterweight selection.

[0057] When the blocking member 400 slides close to the mounting base 200 in the second direction until the clearance part on the blocking member 400 is aligned with the adjustment port on the mounting base 200, the adjustment port is opened, and the two sides of the mounting base 200 are connected. At this time, the handle 100 can pass through the adjustment port in the first direction and connect with the counterweight mechanism to select the counterweight.

[0058] In some embodiments, the blocking member 400 further includes a limiting portion, a blocking portion, and a clearance portion. The limiting portion is slidably disposed on the limiting member 300 and is used to limit the endpoint of the blocking member 400 when it slides toward the mounting base 200. The blocking portion is disposed on one side of the limiting portion and is used to cover the adjustment port to close it. The clearance portion is disposed between the blocking portion and the limiting portion and is connected to both of them respectively. The clearance portion is used to avoid the end of the handle 100 so as to allow the handle 100 to be connected to the counterweight mechanism for counterweight selection.

[0059] Specifically, the limiting part is a plate-shaped component, which is slidably disposed on the limiting member 300. The limiting part slides along the second direction to move away from or close to the top wall of the mounting base 200.

[0060] The shielding part is a plate-shaped component. The shielding part is located on one side of the limiting part and is connected to it through the avoidance part. The maximum cross section of the shielding part is parallel to the side wall of the mounting base 200 and is used to cover and shield the adjustment port that passes through the side wall of the mounting base 200 so that the adjustment port is closed.

[0061] The avoidance part is a bent component, with its two ends extending toward the limiting part and the blocking part respectively and connecting to both. The end of the avoidance part near the blocking part is provided with an avoidance opening or an avoidance area.

[0062] When the limiting part slides along the second direction, the limiting part drives the avoidance part and the blocking part to move relative to the adjustment port on the mounting base 200; when the limiting part slides to the position closest to the top wall of the mounting base 200, this position is the end position when the blocking member 400 slides towards the mounting base 200, and the limiting part is used to restrict the entire blocking member 400 from continuing to slide towards the mounting base 200.

[0063] In some embodiments, the blocking member 400 moves toward the mounting base 200 until the limiting portion is in the position closest to the mounting base, at which point the clearance portion aligns with the end of the handle 100 to allow the handle 100 to connect with the counterweight mechanism for counterweight selection.

[0064] Specifically, the blocking member 400 moves closer to the mounting base 200 along the second direction until the limiting part is at the position closest to the mounting base 200. This position is the endpoint position of the blocking member 400 as it slides closer to the mounting base 200.

[0065] That is, the clearance part can no longer follow the blocking part 400 to move closer to the mounting base 200, so that the position of the clearance part can be aligned with the position of the adjustment port, thereby avoiding the clearance part from moving during the sliding of the blocking part 400 and failing to stably align with the position of the adjustment port.

[0066] Reference Appendix Figure 1 In some embodiments, a first elastic member 500 is disposed between the mounting base 200 and the blocking member 400. The first elastic member 500 is used to normally drive the limiting part away from the mounting base 200, thereby causing the blocking member 400 to abut against the handle 100. The blocking member 400 covers the adjustment port to keep it in a normally closed state.

[0067] Specifically, the first elastic element 500 includes, but is not limited to, a spring, a compression spring, and a spring sheet, and the first elastic element 500 is disposed between the mounting base 200 and the blocking element 400.

[0068] The first elastic member 500 is sleeved on the limiting member 300, with one end of the first elastic member 500 abutting against the mounting base 200 and the other end abutting against the limiting part of the blocking member 400.

[0069] The elastic force of the first elastic element 500 is used to normally drive the blocking element 400 away from the mounting base 200, so that the blocking part of the blocking element 400 covers the adjustment port, so that the adjustment port is kept in a normally closed state, avoiding accidental touch of the handle 100 so that it can directly pass through the adjustment port to connect to the counterweight mechanism for counterweight selection.

[0070] Reference Appendix Figure 1 In some embodiments, one end of the switch 600 is rotatably disposed on the side of the blocking member 400 away from the mounting base 200, and the other end is used to press or release the first elastic member 500 so as to drive the blocking member 400 to slide along the limiting member 300, thereby abutting or avoiding the end of the handle 100 and controlling the opening or closing of the adjustment port.

[0071] Specifically, the switch 600 includes, but is not limited to, a toggle switch. One end of the switch 600 is rotatably disposed on the side of the blocking member 400 away from the mounting base 200, and the other end rotates to move closer to or away from the blocking member 400.

[0072] The switch 600 is used to keep the blocking member 400 in a state of pressing against or releasing the first elastic member 500, thereby facilitating the user to control the adjustment port to be normally open or normally closed.

[0073] When the switch 600 is rotated so that one end of it continuously presses against the blocking member 400, the blocking member 400 presses against the first elastic member 500 to resist its elastic force and slides towards the mounting base 200 until the blocking member 400 slides to the position closest to the mounting base 200, the clearance part is aligned with the adjustment port, and the adjustment port opens to allow the handle 100 to pass through.

[0074] When the switch 600 is rotated so that one end is away from the blocking member 400, the first elastic member 500 releases its elastic force to drive the blocking member 400 to slide away from the mounting base 200. The clearance part intersects with the adjustment port, and the blocking part of the blocking member 400 covers the adjustment port so that the adjustment port is closed. At this time, the handle 100 cannot pass through the adjustment port to connect to the counterweight mechanism for counterweight selection.

[0075] Reference Appendix Figure 1 In some embodiments, the guide 700 is located on the side of the mounting base 200 away from the blocking member 400. The guide 700 is open at both ends and hollow inside. One end of the guide 700 is open at the position where the handle 100 passes through and is fixed on the mounting base 200. The other end is open to guide the handle 100 to extend in.

[0076] Specifically, the guide 700 is a cylindrical component with openings at both ends and a hollow interior. One end of the guide 700 is open to correspond to the adjustment port and is fixed on the mounting base 200, while the other end is open to guide the handle 100 to extend into it.

[0077] After the extension end of the handle 100 is pulled out of the adjustment port, the guide 700 is used to accommodate the extension end of the handle 100 so that the handle 100 is mounted on one side of the adjustment port. When the user wants to use the handle 100 to connect the counterweight mechanism for counterweight selection, there is no need to spend time aligning the extension end of the handle 100 with the adjustment port.

[0078] Reference Appendix Figure 1 In some embodiments, a second elastic member 800 is disposed between the guide 700 and the handle 100, and the second elastic member 800 is used to normally drive the handle 100 away from the mounting base 200 in a first direction.

[0079] Specifically, the second elastic element 800 includes, but is not limited to, a spring, a compression spring, and a spring sheet, and the second elastic element 800 is disposed between the guide 700 and the handle 100.

[0080] The second elastic element 800 is used to normally drive the handle 100 away from the mounting base 200 in the first direction.

[0081] When the user uses the handle 100 to connect to the counterweight mechanism for counterweight selection, the user pushes the handle 100 in the first direction to compress the second elastic element 800, and the extension end of the handle 100 passes through the adjustment port to connect to the counterweight mechanism for counterweight selection.

[0082] When the user releases the force, the second elastic element 800 can release the elastic force to push the handle 100 to automatically pull out the adjustment port for reset, simplifying the adjustment steps.

[0083] In some embodiments, the abutment boss is disposed within the guide 700, the inner diameter of the abutment boss is greater than the outer diameter of the end of the handle 100 extending into, and the inner diameter of the abutment boss is less than the outer diameter of the second elastic member 800. The abutment boss is used to abut against the second elastic member 800 and keep it stable.

[0084] Specifically, the abutment is located inside the guide 700. The end face of the abutment away from the adjustment port is separated from the mounting base 200 by a first distance. The end face of the guide 700 away from the adjustment port is separated from the mounting base 200 by a second distance. The second distance is greater than the first distance, so that a step is formed between the two end faces.

[0085] The inner diameter of the abutting boss is greater than the outer diameter of the end of the handle 100 that extends into it, and the inner diameter of the abutting boss is less than the outer diameter of the second elastic element 800.

[0086] When the second elastic member 800 abuts against the abutting boss, a portion of the second elastic member 800 is located inside the guide 700, and the other portion extends out of the guide 700 to be sleeved outside the extension end of the handle 100 and abut against the gripping end of the handle 100; the displacement of the second elastic member 800 in the first direction and the displacement perpendicular to the first direction are both restricted, and the abutting boss is used to abut against the second elastic member 800 and keep it stable.

[0087] When the user wants to turn on the trigger switch for adjustment, he / she rotates the switch 600 so that one end of it presses against the blocking member 400, which in turn presses against the first elastic member 500 to resist its elastic force and slides towards the mounting base 200 until the blocking member 400 slides to the position closest to the mounting base 200, at which point the clearance part is aligned with the adjustment port and the adjustment port remains open.

[0088] By grasping the gripping end of the handle 100 and compressing the second elastic element 800 in the first direction, the insertion end of the handle 100 passes through the guide 700 and extends into the open adjustment port, thus connecting to the counterweight mechanism for counterweight selection; when the user releases the force, the second elastic element 800 releases its elastic force to push the handle 100 to automatically pull out of the adjustment port for reset.

[0089] When the user wants to turn off the trigger switch to prevent adjustment, he / she rotates the switch 600 so that one end is away from the blocking member 400. The first elastic member 500 releases its elastic force to drive the blocking member 400 to slide away from the mounting base 200. The avoidance part intersects with the adjustment port, and the blocking part of the blocking member 400 covers the adjustment port to keep the adjustment port closed. At this time, the insertion end of the handle 100 cannot pass through the adjustment port to connect to the counterweight mechanism for counterweight selection. Specific Implementation Example 2

[0091] This application also provides a trigger switch, which differs from the specific embodiment in that the blocking member 400 is slidably disposed on the limiting member 300. The blocking member 400 is provided with a clearance part. By sliding the blocking member 400 relative to the limiting member 300, the clearance part is aligned with or staggered with the adjustment port to block or allow the handle 100 to pass through the mounting base 200 to connect to the counterweight mechanism for counterweight selection.

[0092] The difference is that the blocking member 400 is rotatably mounted on the limiting member 300, and the blocking member 400 does not have a clearance part.

[0093] By rotating the blocking member 400 relative to the mounting base 200, the adjustment port is blocked when the blocking member 400 is close to the side wall of the mounting base 200, or opened when the blocking member 400 is away from the side wall of the mounting base 200; the other structures are the same and will not be described in detail here.

[0094] Specifically, the blocking member 400 is rotatably mounted on the limiting member 300. When the blocking member 400 rotates to approach the side wall of the mounting base 200, the adjustment port on the mounting base 200 is gradually blocked until the blocking member 400 is in contact with the side wall of the mounting base 200, at which point the adjustment port is completely blocked and closed. At this time, the handle 100 cannot pass through the adjustment port in the first direction to connect with the counterweight mechanism for counterweight selection.

[0095] When the blocking member 400 is rotated away from the side wall of the mounting base 200, the adjustment port on the mounting base 200 is gradually opened until the blocking member 400 is rotated to be perpendicular to the side wall of the mounting base 200, at which point the adjustment port is fully opened. At this time, the handle 100 can pass through the adjustment port in the first direction to connect with the counterweight mechanism for counterweight selection.

[0096] It should be noted that the rotation direction of the blocking component 400 should be set according to the actual situation, and no specific limitation is made here. Specific Implementation Example 3

[0098] This application also provides a trainer equipped with a trigger switch as described in the first or second embodiment above, to block or allow the handle 100 to connect to the counterweight mechanism for counterweight selection.

[0099] This application provides a trigger switch and a training device equipped with it. The limiting member 300 and the blocking member 400 cooperate to allow the blocking member 400 to abut or avoid the end of the handle 100, thereby blocking or allowing the handle 100 to connect to the counterweight mechanism for counterweight selection. This prevents accidental activation of the handle 100, thus reducing the probability of safety accidents and saving inspection time. By providing a first elastic member 500, the blocking member 400 is normally driven away from the mounting base 200, causing the blocking member 400 to abut the end of the handle 100, preventing the handle 100 from connecting to the counterweight mechanism. The switch... The component 600 keeps the blocking component 400 in a state of pressing against or releasing the first elastic component 500, thereby keeping the blocking component 400 in a state of abutting against or avoiding the end of the handle 100; by providing the guide component 700 to guide the handle 100 through the mounting base 200, excessive calibration time is avoided; by providing the second elastic component 800 to normally drive the handle 100 to move in a direction away from the mounting base 200, it is prevented from remaining connected to the counterweight mechanism after adjustment, thus affecting the reset of the blocking component 400; by providing the abutment boss, the second elastic component 800 works stably between the guide component 700 and the handle 100.
