Description

Technical Field

[0001] This utility model relates to the field of furniture, and in particular to a flip-up footrest. Background Technology

[0002] In furniture and vehicle seating, footrests are common accessories used to improve user comfort. However, traditional footrest designs have many shortcomings that limit their user experience and functional expansion.

[0003] On the one hand, non-flippable footrests not only take up too much space on the seat, but also cause a lot of waste during packaging and transportation.

[0004] On the other hand, most flip-up footrests are cumbersome and complicated to switch between folding and unfolding. Common methods use mechanical structures such as manually inserting and removing pins or flipping latches to fix the footrest position. Users not only need to bend over and reach out to operate, but these operations can also easily cause hand fatigue when used frequently. This is especially inconvenient for the elderly, disabled people, or passengers who have been traveling for a long time.

[0005] In conclusion, there is an urgent need for a new design of a flip-up footrest that is self-circulating, easy to operate, and highly stable, in order to overcome the limitations of existing technologies, meet people's growing needs for comfort and functionality, and improve the overall quality of various seating facilities. Summary of the Invention

[0006] To address the aforementioned technical problems, this utility model provides a flip-up footrest, comprising a base, a support, and a self-circulating flipping mechanism. The support is rotatably connected to the base. The self-circulating flipping mechanism includes a locking seat, a locking member, and a rotatably mounted guide. The locking seat is fixed to the base. An elastic element within the support provides elasticity to the locking member, ensuring it always abuts against the relevant components. The locking seat has first and second locking slots. The footrest has retracted and extended states. The locking member is retracted in the first locking slot and extended in the second locking slot, with the second locking slot preventing backward flipping. The locking member moves from the first locking slot to the second locking slot, pushing the guide to rotate. The guide assists the locking member in leaving the first locking slot, achieving a backward flipping and returning to the first locking slot after crossing the second locking slot. No additional switch is required; it can self-circulate and flip, offering convenient operation and high stability, greatly improving the user experience of seating facilities.

[0007] The technical solution of this utility model is implemented as follows:

[0008] A flip-up footrest includes a base, a support, and a self-circulating flipping mechanism disposed between the two. The support is rotatably connected to the base. The self-circulating flipping mechanism includes a locking seat, a locking member, and a guide member rotatably disposed on the locking seat. The locking seat is disposed on the base and remains stationary with the base. The locking member is slidably disposed on the support and rotates around the locking seat together with the support. The support also includes an elastic member to provide elastic force to the locking member to move toward the locking seat. The locking seat has a first locking groove and a second locking groove. The footrest has a folded state and an unfolded state. When the locking member is in the first locking slot, the foot rest is in a retracted state. When the locking member is in the second locking slot, the foot rest is in an extended state. The second locking slot is configured to prevent the locking member and the support member from flipping backward to keep the foot rest in the extended state. When the locking member moves from the first locking slot toward the second locking slot, the locking member pushes the guide member to rotate in the same direction. The guide member is configured to make the locking member leave the first locking slot and flip backward on the support member, so that the locking member abuts against the guide member and rotates backward together with the guide member to cross the second locking slot and return to the first locking slot.

[0009] The elastic element ensures that the locking element always abuts against the locking element, whether the locking element is against the locking seat or in the locking groove. When the locking element reaches the guide element, the elastic element causes the locking element to abut against the guide element instead of contacting the locking seat, thus allowing the locking element to pass over the second locking groove and switch from the unfolded state to the retracted state. No switch is required to operate, and a self-circulating footrest flipping motion is achieved.

[0010] Preferably, the locking seat is further provided with a first limiting part and a second limiting part. The guide includes a pushing part and a lifting part that both protrude from the locking seat in the radial direction, and the pushing part protrudes from the lifting part in the radial direction. The pushing part is configured such that when the locking member moves, the locking member pushes the pushing part to make the guide rotate together. The lifting part is configured to make the locking member leave the surface of the locking seat. When switching from the retracted state to the unfolded state, the rotation direction of the guide is the unfolding direction. When switching from the unfolded state to the retracted state, the guide rotates in the opposite direction and the rotation direction is the retracting direction. The first limiting part is configured such that when the locking member is located in the first locking groove, the first limiting part abuts against the guide and prevents the guide from continuing to move in the retracting direction. The second limiting part is configured such that when the locking member is located in the second locking groove, the second limiting part abuts against the guide and prevents the guide from continuing to move in the unfolding direction. The support member flips forward, and the locking member directly pushes the pusher to rotate the guide member toward the second limiting part until the locking member enters the second locking groove. At this time, the support member cannot flip backward to achieve support, but cannot return to the folded state. Therefore, the support member continues to flip forward, the locking member continues to rotate, and the guide member is blocked by the second limiting part and cannot move. The locking member moves from the pusher to the lifting part and disengages from the locking seat. At this time, the support member flips backward, and the locking member pushes the pusher to rotate backward on the lifting part until the guide member is blocked by the first limiting part. The locking member returns from the lifting part to the first locking groove through the pusher, realizing self-circulating flipping.

[0011] Preferably, the locking member includes a lock head with an inclined surface; the first locking groove has an inclined surface adjacent to the second locking groove, and the second locking groove has an inclined surface located at the front. This allows the support member to flip forward without obstruction, and also allows the lock head to leave the locking groove and come onto the guide member. The pushing part of the guide member also has the same inclined surface as the first and second locking grooves, allowing the lock head to pass through the pushing part onto the lifting part.

[0012] Preferably, the locking seat includes a rotating shaft and an actuating part, the diameter of the rotating shaft is smaller than that of the actuating part, and the first locking groove, the second locking groove, the first limiting part and the second limiting part are all provided on the actuating part; the rotating shaft is configured to allow the support member to be rotatably connected to the base.

[0013] Preferably, the guide further includes an abutting portion configured to abut against the first limiting portion, and when the abutting portion abuts against the first limiting portion, the pushing portion is located in front of the first locking groove. This ensures that when the guide returns to its original position with the locking member, the locking member returns precisely to the first locking groove.

[0014] Preferably, the base has two integrally formed bearings extending to the left and right respectively, a locking seat is sleeved on the bearing and circumferentially limited by the bearing, and a guide is sleeved on the bearing and rotatably connected to the bearing.

[0015] Preferably, the bearing seat has a limiting block at its end near the base, and the limiting block engages with the locking seat. This achieves circumferential limiting of the bearing seat and the locking seat.

[0016] Preferably, the support includes a main body and a cover plate. The main body is provided with a sliding seat, the locking member is inserted into the sliding seat, and the elastic member is disposed in the sliding seat. The cover plate is fixedly connected to the main body, and the locking seat is located between the cover plate and the main body. The cover plate is U-shaped to avoid the base.

[0017] Preferably, the guide has a rotating protrusion with a diameter smaller than that of the guide, and the rotating protrusion abuts against the locking seat. The rotating protrusion provides rotational friction for the guide, allowing the guide to be smoothly pushed by the locking member.

[0018] Preferably, the base is V-shaped. This serves two purposes: firstly, it limits the excessive rotation of the support member; secondly, when the locking member is in the second locking groove, the support member can continue to rotate forward a certain distance, allowing the locking member to come onto the guide member.

[0019] The design starting point, concept, and beneficial effects of this utility model, which adopts the above technical solution, are as follows:

[0020] The elastic element ensures that the locking element always abuts against the locking element, whether the locking element is against the locking seat or in the locking groove. When the locking element reaches the guide element, the elastic element causes the locking element to abut against the guide element instead of contacting the locking seat, thus allowing the locking element to pass over the second locking groove and switch from the unfolded state to the retracted state. No switch is required to operate, and a self-circulating footrest flipping motion is achieved. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0034] In the description of this utility model, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] The specific implementation of this utility model is as follows:

[0036] like Figure 1-10As shown, this utility model provides a flip-up foot rest, including a base 1, a support 2, and a self-circulating flipping mechanism disposed between the two. The support 2 is rotatably connected to the base 1. The self-circulating flipping mechanism includes a locking seat 3, a locking member 8, and a guide member 9 rotatably disposed on the locking seat 3. The locking seat 3 is disposed on the base 1 and remains stationary with the base 1. The locking member 8 is slidably disposed on the support 2 and rotates around the locking seat 3 together with the support 2. The support 2 is also provided with an elastic member 10 to provide elastic force to the locking member 8 moving towards the locking seat 3. The locking seat 3 is provided with a first locking groove 4 and a second locking groove 5. The foot rest has a folded state. In the unfolded state; when the locking member 8 is located in the first locking groove 4, the foot rest is in the retracted state; when the locking member 8 is located in the second locking groove 5, the foot rest is in the unfolded state. The second locking groove 5 is configured to prevent the locking member 8 and the support member 2 from flipping backward to keep the foot rest in the unfolded state; the locking seat 3 is also provided with a first limiting part 6 and a second limiting part 7. The guide member 9 includes a pushing part 91 and a lifting part 92 that both protrude from the locking seat 3 in the radial direction, and the pushing part 91 protrudes from the lifting part 92 in the radial direction; the pushing part 91 is configured such that when the locking member 8 moves, the locking member 8 pushes the pushing part 91 to make the guide member 9 rotate together; the lifting part 9... Configuration 2 is configured such that the locking member 8 leaves the surface of the locking seat 3; when switching from the retracted state to the unfolded state, the rotation direction of the guide member 9 is the unfolding direction; when switching from the unfolded state to the retracted state, the guide member 9 rotates in the opposite direction and the rotation direction is the retracting direction; the first limiting part 6 is configured such that when the locking member 8 is located in the first locking groove 4, the first limiting part 6 abuts against the guide member 9 and prevents the guide member 9 from continuing to move in the retracting direction; the second limiting part 7 is configured such that when the locking member 8 is located in the second locking groove 5, the second limiting part 7 abuts against the guide member 9 and prevents the guide member 9 from continuing to move in the unfolding direction; the supporting member 2 flips forward, and the locking member 8 directly pushes the pushing part 91 to cause the guide member 8 to rotate forward. The guide 9 rotates toward the second limiting part 7 until the locking part 8 enters the second locking groove 5. At this time, the support 2 cannot be flipped backward to achieve support capacity, but cannot return to the folded state. Therefore, the support 2 continues to be flipped forward, the locking part 8 continues to rotate, and the guide 9 is blocked by the second limiting part 7 and cannot move. The locking part 8 moves from the pushing part 91 to the lifting part 92 and disengages from the locking seat 3. At this time, the support 2 is flipped backward, and the locking part 8 pushes the pushing part 91 to rotate backward on the lifting part 92 until the guide 9 is blocked by the first limiting part 6. The locking part 8 returns from the lifting part 92 through the pushing part 91 to the first locking groove 4, realizing self-circulating flipping.

[0037] Specifically, such as Figure 4-7As shown, both the first limiting part 6 and the second limiting part 7 protrude from the end face of the locking seat 3 to the side. The guide 9 also includes an abutting part 93, which is configured to abut against the first limiting part 6. When the abutting part 93 abuts against the first limiting part 6, the pushing part 91 is located in front of the first locking groove 4. This allows the locking part 8 to return to its original position when the guide 9 carries the locking part 8 back into the first locking groove 4. The base 1 is V-shaped, which firstly restricts the excessive rotation of the support 2, and secondly allows the support 2 to continue to rotate forward a certain distance when the locking part 8 is in the second locking groove 5, so that the locking part 8 can come onto the guide 9. Two bearing seats 11 extending to the left and right are integrally formed on the base 1. The locking seat 3 is sleeved on the bearing seats 11 and circumferentially limited by the bearing seats 11. The guide 9 is sleeved on the bearing seats 11 and rotatably connected to the bearing seats 11. The seat 11 has a limiting block 111 at its end near the base 1. The limiting block 111 engages with the locking seat 3 to achieve circumferential limiting between the bearing seat 11 and the locking seat 3. The support member 2 includes a main body 21 and a cover plate 22. The main body 21 has a sliding seat 211. The locking member 8 is inserted into the sliding seat 211. The elastic member 10 is disposed in the sliding seat 211. The cover plate 22 is fixedly connected to the main body 21. The locking seat 3 is located between the cover plate 22 and the main body 21. The cover plate 22 is U-shaped and can avoid the base 1. The locking seat 3 includes a rotating shaft 31 and an actuating part 32. The diameter of the rotating shaft 31 is smaller than that of the actuating part 32. The first locking groove 4, the second locking groove 5, the first limiting part 6, and the second limiting part 7 are all disposed on the actuating part 32. The rotating shaft 31 is configured to allow the support member 2 to be rotatably connected to the base 1.

[0038] The locking member 8 includes a lock head 81 with an inclined surface; the first locking groove 4 has an inclined surface close to the second locking groove 5, and the second locking groove 5 has an inclined surface at the front, allowing the support member 2 to flip forward unimpeded, and also allowing the lock head 81 to leave the locking groove and come onto the guide member 9. The pushing part 91 of the guide member 9 also has the same inclined surface as the first locking groove 4 and the second locking groove 5, allowing the lock head 81 to come onto the lifting part 92 via the pushing part 91. The guide member 9 has a rotating protrusion 94, the diameter of which is smaller than the diameter of the guide member 9, and the rotating protrusion 94 abuts against the locking seat 3; the rotating protrusion 94 is used for the rotational friction of the guide member 9, so that the guide member 9 can be smoothly pushed by the locking member 8.
