Description

Technical Field

[0001] This invention belongs to the technical field of treadmills, and in particular relates to a manual vertical folding treadmill and a folding method. Background Technology

[0002] With the popularization of healthy living concepts, the market demand for home fitness equipment continues to grow. Walking machines, as a low-impact, space-saving, and low-noise aerobic fitness device, are especially suitable for small apartments and offices. Compared to large treadmills, walking machines have a simpler structure and are more affordable; however, even so, their unfolded length is usually 1.2 to 1.5 meters, which is still a significant amount of space in urban homes where space is at a premium. Therefore, folding functionality has become an important design direction for walking machines—users can fold up the running platform when not in use, allowing it to stand against a wall or be tucked under a bed or sofa, saving considerable space.

[0003] However, some existing folding treadmills use motors or electric push rods to drive the folding mechanism, which not only increases manufacturing costs but also makes the electric components prone to motor jamming, push rod oil leakage, or circuit failures during long-term use, leading to folding function failure and making repairs difficult. Meanwhile, existing manual folding treadmills usually require users to bend over and forcefully lift the running platform, which is strenuous. Furthermore, once folded, they rely solely on simple latches or friction to maintain their position, making them susceptible to self-unfolding due to vibration or accidental activation, or accidental folding during exercise, posing serious safety hazards. Therefore, we provide a manual upright folding treadmill and folding method to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a manual vertical folding treadmill and a folding method. By using the folding component, there is no need for components such as motors and electric push rods, which reduces manufacturing costs and failure rates. At the same time, the use of the self-locking component effectively avoids the safety hazards of accidental folding during use or accidental unfolding during storage.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention provides a manual vertical folding treadmill, including a front running platform and a rear running platform. A running belt is driven between the rollers of the front and rear running platforms. A motor unit is installed in a groove on the end of the front running platform away from the rear running platform, and the motor unit is driven by the rollers of the front running platform. A support base is provided at the lower part between the front and rear running platforms. Folding components are provided at the front and rear parts of the upper part of the support base. The folding components include connectors and T-shaped support components. Two sets of connectors are provided and are arranged in a front-to-back arrangement. The connectors are fixed at the corresponding ends of the front and rear running platforms. The T-shaped support components are fixedly connected to the support base. Two curved strips and two straight strips are provided between the T-shaped support components and the connectors. The two curved strips are located between the two straight strips. A self-locking component is provided on the side of one of the folding components. The self-locking component includes a double-through-hole metal part and a pin. The double-through-hole metal part is fixed on the support base. Two pins are provided and are slidably disposed in the corresponding through holes of the double-through-hole metal part.

[0007] The present invention is further configured such that a vertical groove is provided through the vertical part in the middle of the T-shaped support member, and a horizontal groove is provided through the horizontal part of the T-shaped support member located on both sides of the vertical groove.

[0008] The invention is further configured such that the middle bends of two adjacent curved strips are hinged by a connecting pin, and the two adjacent curved strips are arranged in an X-shape, with the straight strip and the lower end of the adjacent curved strips hinged by a connecting pin.

[0009] The invention is further configured such that the upper ends of both the straight bar and the curved bar are hinged to the corresponding connecting parts by a connecting pin, wherein the two ends of the connecting pin at the bend connection in the middle of the two curved bars are slidably disposed in the corresponding vertical groove, and the two ends of the connecting pin at the hinge connection between the lower ends of the curved bar and the straight bar are slidably disposed in the corresponding horizontal groove.

[0010] The invention is further configured such that rollers are installed on the front and rear parts of the left and right side walls of the support base.

[0011] The invention is further configured such that an installation strip is installed at the lower end of the rear running platform, and a telescopic pull rod is installed on the opposite side of the surface of the front running platform.

[0012] The invention is further configured such that the pin heads of the two pins are inserted into the corresponding vertical slots, and a linkage block is provided on the end face of the double-through-hole metal part away from the folding assembly. The end face of each pin is fixedly connected to the linkage block, and a mounting shaft is fixed on the end face of the linkage block opposite to the end face of the double-through-hole metal part, and a pull ring is provided at the end of the mounting shaft.

[0013] The invention is further configured such that each pin is fitted with a spring on its outer side, and the other end of the spring abuts against the inner end face of the through hole of the double through hole metal part. The upper end face of the double through hole metal part is provided with a limiting groove that communicates with the inside of the corresponding through hole. A limiting member with one end inside the limiting groove is fixed at the upper end of the pin.

[0014] The present invention also provides a folding method for a manual upright folding walking machine, which is operated according to the following steps:

[0015] S1: When the treadmill is in the unfolded state, the pin is inserted into the corresponding vertical slot. Therefore, the pin head will limit the connecting pin shaft at the upper end of the vertical slot, thereby limiting the folding component.

[0016] S2: When the treadmill needs to be folded, first pull the pull ring with one hand. The pull ring will drive the linkage block to move away from the metal part with double through holes through the mounting shaft. Then the linkage block will drive the pin to slide in the through hole of the metal part with double through holes, and the pin head at the end of the pin will be dislodged inside the vertical groove. Thus the connecting pin can slide up and down in the vertical groove.

[0017] S3: After the previous step, the staff controls the front and rear running platforms to rotate relative to each other in the upward direction. The front and rear running platforms will drive the connecting parts connected to them to rotate synchronously relative to each other, so that the opposite ends of the two sets of connecting parts move downward and compress the two curved strips downward. At this time, the connecting pins at the bends of the two curved strips slide downward along the vertical groove.

[0018] S4: The ends of the two sets of connectors that are relatively far apart will be tilted upwards, which will pull the straight bar upwards, thereby simultaneously driving the connecting pin at the hinge of the straight bar and the curved bar to slide in the transverse groove.

[0019] S5: When the connecting pin is at the bottom of the vertical groove, the folding is complete. Then the pull ring can be released, and the spring will push the pin to reset and re-insert it into the vertical groove. The pin will then limit the corresponding connecting pin at the bottom of the vertical groove, thereby limiting the folded treadmill.

[0020] The present invention has the following beneficial effects:

[0021] 1. This invention sets up a support base and a folding assembly between the front and rear running platforms. Folding can be completed by manually lifting the front and rear running platforms. When the front and rear running platforms are closed upwards, the connecting piece rotates inwards and presses down on the center of the curved strip, causing its connecting pin to slide down along the vertical groove. At the same time, the connecting pin at the lower end of the curved strip and the straight strip slides outwards along the horizontal groove, thereby realizing the vertical closure of the running platforms. This purely mechanical linkage structure does not require components such as motors and electric push rods, reducing manufacturing costs and failure rates. At the same time, it avoids the jamming or power failure problems that may occur with electric folding. The operation is intuitive and the maintenance is simple.

[0022] 2. This invention features a self-locking component on the side of one of the folding components. In the unfolded state, the pin inserts into the vertical slot to limit the connecting pin at the upper end, preventing the running platform from folding accidentally. When folding is required, pull the pull ring with one hand to disengage the pin from the vertical slot. After unlocking, manually close the running platform. Once folded in place, release the pull ring, and the spring pushes the pin to automatically reset and insert into the vertical slot, locking the connecting pin at the bottom to prevent the running platform from opening on its own. This self-locking structure is simple to operate, securely locks, and effectively avoids the safety hazards of accidental folding during use or accidental unfolding during storage.

[0023] Of course, any product implementing this invention does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1 to 9This invention relates to a manual vertical folding treadmill, comprising a front running platform 1 and a rear running platform 3. A running belt 2 is connected between the rollers of the front running platform 1 and the rollers of the rear running platform 3. A motor assembly 101 is installed in a groove on the end of the front running platform 1 away from the rear running platform 3, and the motor assembly 101 is connected to the rollers of the front running platform 1. A support base 4 is provided at the lower part between the front running platform 1 and the rear running platform 3. Folding components 6 are provided at both the front and rear parts of the upper end of the support base 4. The folding components 6 include connectors 601 and T-shaped support members 605. Two sets of connectors 601 are provided and arranged in a front-to-back configuration. Fixed at the opposite ends of the corresponding front running platform 1 and rear running platform 3, the T-shaped support 605 is fixedly connected to the support base 4. Two curved strips 602 and two straight strips 603 are provided between the T-shaped support 605 and the connecting piece 601, and the two curved strips 602 are located between the two straight strips 603. One of the folding components 6 has a self-locking component 7 on its side. The self-locking component 7 includes a double-hole metal part 701 and a pin 704. The double-hole metal part 701 is fixed on the support base 4. There are two pins 704, which are slidably disposed in the corresponding through holes of the double-hole metal part 701.

[0038] Rollers 401 are installed on the front and rear parts of the left and right side walls of the support base 4. An installation strip 301 is installed at the lower end of the rear running platform 3. A telescopic pull rod 5 is installed on the opposite side of the surface of the front running platform 1.

[0039] When the treadmill is unfolded, the self-locking component 7 locks the folding component 6 in place, preventing the folding component 6 from moving and keeping the running platform level and stable, allowing for safe weight-bearing movement. When folding is required, pull the pull ring 706 with one hand to fold the front running platform 1 and the rear running platform 3 upwards into an upright position. Release the pull ring 706, and the pin 704 will automatically insert into the vertical slot 607 under the push of the spring 705, locking the connecting pin 604 in the bottom position. The folded state remains fixed and will not come apart on its own. After folding and locking, the rollers 401 of the support base 4 touch the ground, and the telescopic pull rod 5 can be stretched to easily pull and move the treadmill. It can be easily pushed under the bed, into a cabinet, or into a corner for storage.

[0040] Example 1, according to Figure 4 , Figure 5 and Figure 7It can be seen that the vertical part of the T-shaped support 605 has a vertical groove 607 through it, and the horizontal parts of the T-shaped support 605 on both sides of the vertical groove 607 have horizontal grooves 606 through them. The middle bends of the two adjacent curved strips 602 are hinged by a connecting pin 604, and the two adjacent curved strips 602 are arranged in an X-shape. The lower ends of the straight strip 603 and the adjacent curved strip 602 are hinged by a connecting pin 604. The upper ends of the straight strip 603 and the curved strip 602 are both hinged to the corresponding connector 601 by a connecting pin 604. The two ends of the connecting pin 604 at the bend of the two curved strips 602 are slidably disposed in the corresponding vertical groove 607, and the two ends of the connecting pin 604 at the lower hinge of the curved strip 602 and the straight strip 603 are slidably disposed in the corresponding horizontal groove 606.

[0041] In this embodiment, in the unfolded state, the two sets of curved strips 602 are open, providing the highest support height. When the front and rear running platforms 3 are lifted up and down, the connecting piece 601 rotates inward and presses down on the intersection center of the curved strips 602, causing its connecting pin 604 to slide down along the vertical groove 607. At the same time, the connecting pin 604 at the lower end of the curved strips 602 and the straight strips 603 slides outward along the transverse groove 606, thereby causing the front running platform 1 and the rear running platform 3 to vertically close upward. Through pure mechanical linkage, stable manual folding without electric power or complex structure is achieved. The movement is smooth, the load-bearing capacity is strong, and it is not easily deformed. After folding, it occupies very little space.

[0042] Example 2, based on Example 1, according to Figure 5 , Figure 8 and Figure 9 It can be seen that the pin heads of the two pins 704 are inserted into the corresponding vertical slots 607. The end face of the double-through-hole metal part 701 away from the folding component 6 is provided with a linkage block 702. The end face of each pin 704 is fixedly connected to the linkage block 702. The linkage block 702 is fixed with a mounting shaft 703 opposite to the end face of the double-through-hole metal part 701. The end of the mounting shaft 703 is provided with a pull ring 706. The surface of each pin 704 is fitted with a spring 705. The other end of the spring 705 abuts against the inner end face of the through hole of the double-through-hole metal part 701. The upper end face of the double-through-hole metal part 701 is provided with a limiting groove 707 that communicates with the inside of the corresponding through hole. The end of the upper pin 704 is fixed with a limiting member 708 that is located inside the limiting groove 707.

[0043] In this embodiment, when unlocking, the user only needs to pull the pull ring 706 outward with one hand. The two pins 704 will retract synchronously through the mounting shaft 703 and the linkage block 702, completely disengaging from the vertical groove 607 and releasing the restriction on the connecting pin shaft 604.

[0044] After the pull ring 706 is released, the spring 705 immediately pushes the pin 704 to automatically reset and insert, thus locking it again. At the same time, the limit member 708 and the limit groove 707 cooperate to prevent the pin 704 from being pulled out excessively and falling off, realizing self-locking when unfolded, self-locking when folded, and simultaneous unlocking with one hand. The operation is simple, the locking is firm, and it avoids accidental folding during use or accidental unfolding during storage, making it extremely safe.

[0045] Example 3: The present invention also provides a folding method for a manual upright folding treadmill, which is operated according to the following steps:

[0046] S1: When the treadmill is in the unfolded state, the pin 704 is inserted into the corresponding vertical slot 607. Therefore, the pin head of the pin 704 will limit the connecting pin 604 to the upper end of the vertical slot 607, thereby limiting the folding component 6.

[0047] S2: When the treadmill needs to be folded, first pull the pull ring 706 with one hand. The pull ring 706 drives the linkage block 702 to move away from the double-through-hole metal part 701 through the mounting shaft 703. Then the linkage block 702 will simultaneously drive the pin 704 to slide in the through hole of the double-through-hole metal part 701, and the pin head at the end of the pin 704 will disengage inside the vertical groove 607. Thus, the connecting pin 604 can slide up and down in the vertical groove 607.

[0048] S3: After the previous step, the staff controls the front running platform 1 and the rear running platform 3 to rotate relative to each other in the upward direction. This causes the connecting parts 601 connected to them to rotate synchronously relative to each other, so that the opposite ends of the two sets of connecting parts 601 move downward and compress the two bent strips 602 downward. At this time, the connecting pins 604 at the bends of the two bent strips 602 slide downward along the vertical groove 607.

[0049] S4: The relatively distant ends of the two sets of connectors 601 will be tilted upwards, thereby pulling the connecting straight bar 603 upwards, which will simultaneously drive the connecting pin 604 at the hinge of the straight bar 603 and the curved bar 602 to slide in the transverse groove 606.

[0050] S5: When the connecting pin 604 is at the bottom of the vertical groove 607, the folding is complete. Then the pull ring 706 can be released, and the spring 705 will push the pin 704 to reset and re-insert it into the vertical groove 607. The pin 704 will then limit the corresponding connecting pin 604 at the bottom of the vertical groove 607, thereby limiting the folded treadmill.
