Description

Technical Field

[0001] The present application belongs to the technical field of treadmills, and in particular relates to a push-type foldable handrail and a treadmill. Background Art

[0002] As a structure that often appears in people's lives, handrails are widely used in many fields. For example, they are used in treadmills to provide support for people when running. However, due to the consideration of assembly, transportation, and storage, some handrails are designed to be foldable. When they need to be stored, the handrails can be folded to reduce the space they occupy. However, the handrails in the prior art are difficult to fold, which causes inconvenience to users.

[0003] Taking the armrests used on treadmills as an example, the patent with application number 202223427764.8 discloses a convenient button-type treadmill armrest folding mechanism, including a pin and a rotating plate. The rotating plate is provided with a sliding groove. The pin includes a button and a first cylinder and a second cylinder. The button is arranged on the side of the armrest, and the second cylinder is adapted to the sliding groove of the rotating plate. When the armrest needs to be stored, the user needs to first press the button on the side of the armrest, and then push the second cylinder into the sliding groove, and at the same time rotate the rotating plate to completely insert the second cylinder into the sliding groove, so that the rotating plate obtains freedom, and then realizes rotation through the sliding cooperation between the sliding groove and the second cylinder. Such a setting has the following problems: on the one hand, the button is arranged on the side of the armrest. Since the user usually holds the armrest when supporting it, it is easy to accidentally touch the button to push the second cylinder into the sliding groove, so that the rotating plate gains freedom and rotates, which brings the risk of imbalance to the user; on the other hand, when storing the armrest, the user needs to press the button horizontally first, push the second cylinder into the sliding groove, and then rotate the rotating plate vertically or in other directions. This means that during the folding process of the armrest, the user needs to operate the button with one hand and hold the rotating plate with the other hand to rotate the rotating plate, which causes inconvenience to the user when storing.

[0007] The push-type foldable armrest described in this application also includes the following technical features:

[0008] The toggle portion is rotatably connected to the handrail frame, the distance between the pressing portion and the rotation point of the toggle portion and the handrail frame is not less than one quarter of the length of the toggle portion, and / or the distance between the pressing portion and the connecting end of the toggle portion and the limiting mechanism is not less than one third of the length of the toggle portion.

[0009] The toggle portion has a rotating end rotatably connected to the handrail frame, one of the handrail frame and the rotating end is provided with a rotating protrusion, and the other is provided with a rotating through groove adapted to the rotating protrusion, and the toggle portion is rotated relative to the handrail frame through the cooperation between the rotating protrusion and the rotating through groove.

[0010] The toggle portion includes two toggle pieces located at the rotating end and opposite to each other. The two toggle pieces are respectively in contact with the side walls of the handrail frame. The rotating protrusion is arranged on the toggle pieces, and the rotating through groove is arranged on the side wall of the handrail frame.

[0011] The pressing portion has a pressing surface, and when the armrest is in the locking position, the pressing surface is located outside the armrest and lower than the armrest.

[0012] The pressing portion protrudes outward in a direction away from the toggle portion and forms the pressing surface at an end away from the toggle portion. The interior of the pressing portion is hollow to form an abutment groove, and the abutment groove is bent inward to form a stop step. The toggle assembly also includes a matching portion connected to the toggle portion and abutting against the abutment groove, and the abutment groove includes a first abutment surface at a position away from the pressing surface and a second abutment surface located at the top of the stop step.

[0016] A treadmill comprises a treadmill base and also comprises the above-mentioned push-type foldable handrail, wherein the push-type foldable handrail is installed on the treadmill base.

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0018] 1. The push-type foldable armrest of the present application comprises a column and an armrest frame, wherein the armrest frame can be rotated with the column through a rotating mechanism. When the armrest needs to be stored, the rotation of the armrest frame is driven by rotating the rotating mechanism, so that the armrest frame can be rotated to a position closer to the column, thereby reducing the size of the space occupied by the armrest and realizing rapid storage of the armrest; in addition, the foldable armrest of the present application is also provided with a limiting mechanism for limiting the movement of the rotating mechanism, the limiting mechanism has a locking state and an unlocking state, and the limiting mechanism is provided. When the armrest needs to be stored, the limiting mechanism can be adjusted to the unlocking state, so that the rotating mechanism can be freely rotated to change the angle between the armrest frame and the column, thereby realizing storage of the armrest, and when the armrest is in a working state, the limiting mechanism is adjusted to the locking state to prevent the rotating mechanism from rotating, thereby preventing the armrest frame from being locked with the column. The columns rotate relative to each other, which provides a guarantee for the stability of the armrest; moreover, the present application also provides a toggle assembly, including a toggle part with a locking position and an unlocking position and a pressing part acting on the toggle part. When the user needs to fold the armrest, the toggle part can be driven to move from the locking position to the unlocking position by pressing the pressing part, thereby driving the limit mechanism to switch from the locking state to the unlocking state, thereby realizing rapid unlocking of the rotating mechanism; that is, by providing the pressing part, the user can drive the toggle part to move through the pressing part, thereby operating the limit mechanism to lock or unlock the rotating mechanism, and then realize the rotation of the armrest, reducing the difficulty of the user operating the limit mechanism. When the user needs to fold the armrest, the armrest frame can be rotated by only pressing the pressing part, which greatly reduces the complexity of storing the armrest and greatly improves the user experience. Furthermore, the toggle portion of the present application is arranged so that the plane where the movement trajectory between the locked position and the unlocked position lies is coincident or parallel to the plane where the rotation direction of the armrest frame lies. With this arrangement, the force direction in which the user presses the pressing portion is consistent with the force direction in which the armrest frame is rotated. This allows the user to press the pressing portion with one hand to drive the limit mechanism to switch to the unlocked state when folding the armrest frame, and then continue to apply force in the direction of pressing the pressing portion to drive the armrest frame to rotate. This eliminates the need to first apply force toward the pressing portion in a certain direction and then switch the force direction to rotate the armrest. This provides the user with the possibility of folding the armrest with one hand while further reducing the difficulty of folding the armrest, thereby improving the user's storage experience.

[0019] 2. As a preferred embodiment of the present application, the toggle part is arranged to be connected with the armrest frame for rotation, which increases the movement space occupied by the toggle part compared with the movement of the armrest frame, so that the toggle part only needs a relatively small movement space to switch between the locked position and the unlocked position; and the pressing part is arranged to be at a distance of not less than one-fourth of the length of the toggle part from the rotation point of the toggle part and the armrest frame, so as to reserve sufficient torque between the force application point and the rotation point of the pressing part, thereby reducing the amount of force required for the user to drive the toggle part to move through the pressing part, which helps to improve the user experience; and the distance between the pressing part and the connecting end of the toggle part and the limit mechanism is not less than one-third of the length of the toggle part, which helps to shorten the force application distance required by the user to drive the toggle part to move through the pressing part.

[0020] 3. As a preferred embodiment of the present application, the toggle part has a rotating end rotatably connected to the handrail frame, one of the handrail frame and the rotating end is provided with a rotating protrusion, and the other is provided with a rotating through slot adapted to the rotating protrusion, and the toggle part is rotated relative to the handrail frame through the cooperation between the rotating protrusion and the rotating through slot. The provision of the rotating protrusion and the rotating through slot helps to ensure the stability of the rotation of the toggle part, making the rotation process of the toggle part smoother, so that the user can more smoothly operate the toggle part to switch from the locked position to the unlocked position.

[0021] 4. As a preferred embodiment of the present application, the rotating protrusion is arranged on the toggle part, which can reduce the difficulty of processing the rotating protrusion on the handrail frame. When processing the handrail frame, it is only necessary to process the rotating through groove at a preset position by punching or the like, thereby reducing the production difficulty of the handrail frame and optimizing the structural design of the handrail frame; and the rotating end of the toggle part is arranged to include two toggle pieces abutting against the side walls of the handrail frame, so that when the toggle part rotates, the rotating protrusion can be stably placed in the rotating through groove, thereby avoiding the rotating protrusion from falling out of the rotating through groove during the rotation of the toggle part, and providing a guarantee for the rotation stability of the toggle part.

[0022] 5. As a preferred embodiment of the present application, the pressing surface provides a force-applying surface for the user when pressing the pressing part, which helps to improve the user's gripping experience, and setting the pressing surface on the outside of the armrest frame eliminates the need for the user to insert his hand into the armrest frame and then press the pressing part, thereby reducing the user's operating difficulty and improving the user's usage experience; in addition, since the armrest is usually used to provide a supporting function for the user, the force point of the armrest frame when the user supports the armrest is usually on the upper part or side of the armrest frame, and setting the pressing surface lower than the armrest frame can reduce the possibility of the user accidentally touching the pressing part when supporting the handrail, thereby reducing the possibility of mutual rotation between the armrest frame and the column caused by accidentally touching the pressing part.

[0023] 6. As a preferred embodiment of the present application, the interior of the pressing part is arranged to be hollow and to form an abutment groove, so that the matching part connected to the toggle part can fully abut against the abutment groove, thereby increasing the force transmission area from the pressing part to the toggle part and reducing the possibility of stress concentration between the pressing part and the toggle part; and the abutment groove is arranged to bend inward and form a first abutment surface and a second abutment surface, thereby further allowing the pressing force borne by the pressing part to be transmitted to the toggle part in a gradient manner. At the same time, the abutment cooperation between the matching part and the abutment groove can improve the connection stability between the toggle part and the pressing part, thereby optimizing the structural design of the toggle assembly.

[0024] 7. As a preferred embodiment of the present application, the pressing part is provided with an insertion groove, a part of the area of ​​the toggle part is inserted into the insertion groove, and the top surface of the insertion groove forms a third abutting surface abutting against the toggle part. With such a configuration, on the one hand, the connection stability of the toggle part and the pressing part is improved through the insertion and matching of the insertion groove and the toggle part; on the other hand, the third abutting surface provided by the insertion groove also increases the force transmission area from the pressing part to the toggle part, reducing the possibility of stress concentration during the force transmission process from the pressing part to the toggle part.

[0053] like Figures 1 to 12As shown, a push-type foldable handrail comprises a column 1 and a handrail frame 2 connected by a rotating mechanism 3, wherein the handrail frame 2 can be rotated relative to the column 1 by the rotating mechanism 3 so that the handrail frame 2 has a working state and a storage state; further comprising: a limiting mechanism 4 for limiting the movement of the rotating mechanism 3, wherein the limiting mechanism 4 has a locking state for limiting the rotation of the rotating mechanism 3 and an unlocking state for releasing the rotation restriction of the rotating mechanism 3; a toggle assembly, wherein the toggle assembly is installed on the handrail frame 2 and has the function of driving the limiting mechanism 4 to move. The limit mechanism 4 includes a toggle portion 5 for switching from the locked state to the unlocked state and a pressing portion 6 acting on the toggle portion 5, the toggle portion 5 has a locked position corresponding to the locked state of the limit mechanism 4 and an unlocked position corresponding to the unlocked state of the limit mechanism 4, the pressing portion 6 can drive the toggle portion 5 to move from the locked position to the unlocked position, and the plane where the movement trajectory of the toggle portion 5 between the locked position and the unlocked position is located coincides with or is parallel to the plane where the rotation direction of the armrest frame 2 is located.

[0054] The push-type foldable armrest of the present application comprises a column 1 and an armrest frame 2, wherein the armrest frame 2 can be rotated with the column 1 through a rotating mechanism 3. When the armrest needs to be stored, the rotation of the armrest frame 2 is driven by rotating the rotating mechanism 3, so that the armrest frame 2 can be rotated to a position closer to the column 1, thereby reducing the size of the space occupied by the armrest and realizing rapid storage of the armrest; in addition, the foldable armrest of the present application is also provided with a limiting mechanism 4 for limiting the movement of the rotating mechanism 3, the limiting mechanism 4 has a locking state and an unlocking state, and the limiting mechanism 4 is set. When the armrest needs to be stored, the limiting mechanism 4 can be adjusted to the unlocking state, so that the rotating mechanism 3 can be freely rotated to change the angle between the armrest frame 2 and the column 1, thereby realizing storage of the armrest, and when the armrest is in a working state, the limiting mechanism 4 is adjusted to the locking state to prevent the rotating mechanism 3 from rotating, thereby preventing the armrest 2 rotates relative to the column 1 to provide a guarantee for the stability of the armrest; moreover, the present application is also provided with a toggle assembly, including a toggle portion 5 with a locking position and an unlocking position and a pressing portion 6 acting on the toggle portion 5. When the user needs to fold the armrest, the toggle portion 5 can be driven to move from the locking position to the unlocking position by pressing the pressing portion 6, thereby driving the limiting mechanism 4 to switch from the locking state to the unlocking state, thereby realizing the rapid unlocking of the rotating mechanism 3; that is, by providing the pressing portion 6, the user can drive the toggle portion 5 to move through the pressing portion 6, thereby operating the limiting mechanism 4 to lock or unlock the rotating mechanism 3, and then realize the rotation of the armrest, reducing the difficulty of the user to operate the limiting mechanism 4. When the user has a folding demand for the armrest, the armrest frame 2 can be rotated only by pressing the pressing portion 6, which greatly reduces the complexity of storing the armrest and greatly improves the user's experience. Furthermore, the toggle portion 5 of the present application is arranged so that the plane where the movement trajectory between the locked position and the unlocked position lies is coincident or parallel to the plane where the rotation direction of the armrest frame 2 lies. This arrangement allows the user to apply force in the direction of the pressing portion 6 when pressing the pressing portion 6 and to apply force in the direction of rotating the armrest frame 2. This allows the user to press the pressing portion 6 with one hand when folding the armrest frame 2 to drive the limiting mechanism 4 to switch to the unlocked state and then continue to apply force in the direction of pressing the pressing portion 6 to drive the armrest frame 2 to rotate. This eliminates the need to first apply force toward the pressing portion 6 in a certain direction and then switch the force direction to rotate the armrest frame 2. This provides the user with the possibility of folding the armrest with one hand while further reducing the difficulty of folding the armrest, thereby improving the user's storage experience.

[0055] The present application does not limit the connection method between the toggle portion 5 and the handrail frame 2, and it can adopt any one of the following embodiments:

[0056] Embodiment 1: The toggle part 5 is slidably connected to the armrest frame 2. One of the toggle part 5 and the armrest frame 2 is provided with a sliding protrusion, and the other is provided with a sliding groove adapted to the sliding protrusion. The sliding protrusion slides in the sliding groove to drive the toggle part 5 to slide relative to the armrest frame 2.

[0057] Implementation method 2: Figures 1 to 4 As shown, the toggle portion 5 is rotatably connected to the handrail frame 2, the distance between the pressing portion 6 and the rotation point of the toggle portion 5 and the handrail frame 2 is not less than one-fourth of the length of the toggle portion 5, and / or the distance between the pressing portion 6 and the connection end of the toggle portion 5 and the limiting mechanism 4 is not less than one-third of the length of the toggle portion 5. The toggle portion 5 is arranged to be rotatably connected to the handrail frame 2, which increases the movement space occupied by the toggle portion 5 compared to the movement of the handrail frame 2, so that the toggle portion 5 only needs a relatively small movement space to switch between the locked position and the unlocked position; in addition, Figure 4 H1 indicates the distance between the pressing portion 6 and the rotation point of the toggle portion 5 and the armrest 2, H2 indicates the distance between the pressing portion 6 and the connecting end of the toggle portion 5 and the limiting mechanism 4, and H3 indicates the length of the toggle portion 5. Preferably, the pressing portion 6 satisfies the requirements that the distance from the rotation point of the toggle portion 5 and the armrest 2 is not less than one-third of the length of the toggle portion 5, and the distance from the connecting end of the toggle portion 5 and the limiting mechanism 4 is not less than one-third of the length of the toggle portion 5, that is, H1≥1 / 4H3, and H2≥1 / 3H3. Then, while ensuring that sufficient torque is reserved between the force application point and the rotation point of the toggle portion 5, the force required for the user to drive the toggle portion 5 to move through the pressing portion 6 is reduced, and at the same time, the toggle portion 5 does not have an excessively long moving distance, so that the user can drive the toggle portion 5 to move from the locked position to the unlocked position by applying a suitable force and a suitable pressing distance to the pressing portion 6, which helps to improve the user experience.

[0058] As a preferred embodiment of the second implementation mode, Figure 1 , Figure 6 , Figure 8 As shown, the toggle part 5 has a rotating end 51 rotatably connected to the handrail frame 2, one of the handrail frame 2 and the rotating end 51 is provided with a rotating protrusion 52, and the other is provided with a rotating through slot 22 adapted to the rotating protrusion 52, and the toggle part 5 is rotated relative to the handrail frame 2 by the cooperation between the rotating protrusion 52 and the rotating through slot 22. The provision of the rotating protrusion 52 and the rotating through slot 22 helps to ensure the stability of the rotation of the toggle part 5, so that the rotation process of the toggle part 5 is smoother, so that the user can more smoothly operate the toggle part 5 to switch from the locked position to the unlocked position.

[0059] This embodiment does not limit the location and manner of the rotating protrusion 52 and the rotating through groove 22, and any of the following examples may be used:

[0060] Example 1: The toggle portion 5 includes two opposite toggle pieces 53 located at the rotating end 51 , the two toggle pieces 53 are respectively abutted against the side walls of the handrail frame 2 , the rotating protrusion 52 is arranged on the side wall of the handrail frame 2 , and the rotating through groove 22 is arranged on the toggle piece 53 .

[0061] Example 2: Figure 1 , Figure 6 As shown, the toggle part 5 includes two toggle pieces 53 located at the rotating end 51 and opposite to each other, the two toggle pieces 53 are respectively in contact with the side wall of the handrail frame 2, the rotating protrusion 52 is arranged on the toggle piece 53, and the rotating groove 22 is arranged on the side wall of the handrail frame 2. The rotating protrusion 52 is arranged on the toggle part 5, which can reduce the difficulty of processing the rotating protrusion 52 on the handrail frame 2. When processing the handrail frame 2, it is only necessary to process the rotating groove 22 at a preset position by punching or the like, which reduces the production difficulty of the handrail frame 2 and optimizes the structural design of the handrail frame 2; and the rotating end 51 of the toggle part 5 is arranged to include two toggle pieces 53 in contact with the side wall of the handrail frame 2, so that when the toggle part 5 rotates, the rotating protrusion 52 can be stably placed in the rotating groove 22, avoiding the occurrence of the rotating protrusion 52 falling out of the rotating groove 22 during the rotation of the toggle part 5, and providing a guarantee for the rotation stability of the toggle part 5.

[0062] As a preferred implementation of the present application, Figures 1 to 3 , Figure 5 As shown, the pressing portion 6 has a pressing surface 61, and when the armrest 2 is in the locking position, the pressing surface 61 is located outside the armrest 2 and lower than the armrest 2. The pressing surface 61 provides a force application surface for the user when pressing the pressing portion 6, which helps to improve the user's grip experience. The pressing surface 61 is set on the outside of the armrest 2, which saves the user from inserting his hand into the armrest 2 and then pressing the pressing portion 6, reduces the user's operation difficulty, and thus improves the user's experience. In addition, since the armrest is usually used to provide a supporting function for the user, the force point of the armrest 2 when the user supports the armrest is usually on the upper part or the side of the armrest 2, and the pressing surface 61 is set lower than the armrest 2 to reduce the possibility of the user accidentally touching the pressing portion 6 when supporting the handrail, thereby reducing the possibility of the handrail 2 and the column 1 rotating relative to each other due to the accidental touching of the pressing portion 6.

[0063] Preferably, a receiving cavity 21 for receiving the pressing unit is provided at the bottom of the armrest frame 2, and when the toggle portion 5 is located at the locking position, the pressing surface 61 is located outside the receiving cavity 21.

[0064] As a preferred embodiment of this implementation, Figure 5 , Figure 6 As shown, the pressing portion 6 protrudes outward in a direction away from the toggle portion 5 and forms the pressing surface 61 at the end away from the toggle portion 5. The pressing portion 6 is hollow inside to form a contact groove 62. The contact groove 62 is bent inward to form a stop step 621. The toggle assembly also includes a matching portion 7 connected to the toggle portion 5 and abutting against the abutment groove 62. The abutment groove 62 includes a first abutment surface 622 at a position away from the pressing surface 61 and a second abutment surface 623 located at the top of the stop step 621. The interior of the pressing portion 6 is set to be hollow and form an abutment groove 62, so that the matching portion 7 connected to the toggle portion 5 can fully abut against the abutment groove 62, thereby increasing the force transmission area from the pressing portion 6 to the toggle portion 5 and reducing the possibility of stress concentration between the pressing portion 6 and the toggle portion 5; and the abutment groove 62 is set to be bent inward to form a first abutment surface 622 and a second abutment surface 623, so that the pressing force borne by the pressing portion 6 is further transmitted to the toggle portion 5 in a gradient manner. At the same time, the abutment cooperation between the matching portion 7 and the abutment groove 62 can improve the connection stability between the toggle portion 5 and the pressing portion 6, thereby optimizing the structural design of the toggle assembly.

[0065] As a preferred example under this embodiment, Figures 1 to 3 , Figure 5 As shown, when the armrest 2 is in the locking position, the pressing surface 61 is parallel to the length direction of the armrest 2. With such a configuration, when the user needs to fold the armrest 2, the user can first hold the pressing portion 6 and squeeze the pressing portion 6 toward the toggle portion 5. Since the pressing surface 61 is parallel to the length direction of the armrest 2, when the user applies force toward the pressing surface 61, it is convenient for the user to simultaneously hold the armrest 2. When the pressing portion 6 is pressed into place, that is, when the toggle portion 5 reaches the unlocking position, the user can rotate the armrest 2 for storage; that is, the pressing surface 61 configured in this way is convenient for the user to realize the operation of the toggle component with one hand while rotating the armrest 2, which greatly optimizes the structural design of the armrest and improves the user's experience.

[0066] As a preferred implementation of the present application, Figure 5 , Figure 7 As shown, the pressing portion 6 is provided with an insertion groove 63, a part of the area of ​​the toggle portion 5 is inserted into the insertion groove 63, and the top surface of the insertion groove 63 forms a third abutting surface 631 abutting against the toggle portion 5. With such a configuration, on the one hand, the connection stability of the toggle portion 5 and the pressing portion 6 is improved through the insertion and matching of the insertion groove 63 and the toggle portion 5; on the other hand, the third abutting surface 631 provided by the insertion groove 63 also increases the force transmission area from the pressing portion 6 to the toggle portion 5, reducing the possibility of stress concentration during the force transmission process from the pressing portion 6 to the toggle portion 5.

[0067] As a preferred implementation of the present application, Figure 2 , Figure 3 As shown, the toggle assembly further includes an elastic reset member 8 acting on the toggle portion 5, the elastic reset member 8 abuts against the toggle portion 5 and can abut against the toggle portion 5 to move the toggle portion 5 from the unlocked position to the locked position. By setting the elastic reset member 8, the storage work of the armrest is completed, that is, when the armrest frame 2 has been rotated to the preset storage position, the user can release the pressing portion 6, and the toggle portion 5 can be restored from the unlocked position to the locked position under the elastic action of the elastic reset member 8, eliminating the user's reverse force on the toggle portion 5 to change the position of the toggle portion 5 after the armrest is stored, thereby improving the user's use experience; in addition, the user can adjust the pressing feel of the pressing portion 6 by adjusting the elastic size of the elastic reset member 8 or by replacing the elastic reset member 8 with different elasticity, that is, by setting the elastic reset member 8, the needs of different users for different pressing feels of the pressing portion 6 are improved, which helps to improve the user's armrest storage experience.

[0068] Specifically, Figure 2 , Figure 3 , Fig.10 As shown, the limiting mechanism 4 includes a fixing member 41 installed on the column 1 and a locking member 42 installed on the handrail frame 2, and the toggle portion 5 is connected to the locking member 42. When the limiting mechanism 4 is in a locked state, the locking member 42 abuts against the fixing member 41, thereby limiting the rotation of the rotating mechanism 3; when the handrail frame 2 needs to switch from the working state to the storage state, the toggle portion 5 drives the locking member 42 to move and separate it from the fixing member 41, so that the limiting mechanism 4 releases the lock on the rotating mechanism 3, so that the handrail frame 2 can be switched to the storage state through the rotating mechanism 3.

[0069] like Fig.11 , Fig.12 As shown, a treadmill includes a treadmill base 9, and also includes the above-mentioned push-type foldable handrail, and the push-type foldable handrail is installed on the treadmill base 9. The treadmill of the present application is provided with a foldable handrail, and the folding speed of the handrail is fast, and the folding process is simple, which helps to improve the overall folding speed of the treadmill.
