Description

Technical Field

[0001] The utility model relates to the field of furniture, in particular to a seat which is beneficial to packaging and transportation. Background Technique

[0002] A children's chair is a type of seat specially designed for children. Compared with ordinary seats, it is more suitable for the body size of children. At the same time, when designing, more attention will be paid to the growth of children and the safety and comfort brought by the seat.

[0003] In order to increase comfort, it is a good choice to set footrests on children's chairs. However, the footrests protrude forward from the chair legs, and the irregular overall shape increases the occupied space, and it will also cause inconvenience in placing during packaging and transportation, thus increasing the cost of packaging and transportation and reducing the efficiency of the manufacturer. Therefore, how to reduce the cost of packaging and transportation while retaining the footrests is an urgent problem for us to solve. Summary of the Invention

[0004] In order to solve the above technical problems, the utility model provides a seat which is beneficial to packaging and transportation, including a pedal, a rotating tube, a support tube and two chair legs. The pedal is arranged on the rotating tube, the support tube is arranged on the chair legs, and after the rotating tube is sleeved on the support tube, the pedal is rotatably arranged between the two chair legs; in the use state, the rotating tube and the support tube are axially fixed, so that the pedal is horizontal and can support the feet of the human body; in the packaging state, the pedal is turned to be vertical and kept in the same plane as the two chair legs, so that the state shape is more regular, the occupied space of the seat is reduced, and the cost of packaging and transportation is reduced.

[0005] The technical solution of the utility model is realized as follows:

[0006] A seat which is beneficial to packaging and transportation, including a pedal, a rotating tube, a support tube and two chair legs arranged at intervals left and right. The support tube is horizontally arranged on the chair legs, the rotating tube is sleeved on the support tube, the pedal is fixedly connected with the rotating tube, and both the pedal and the rotating tube are located between the two chair legs; there are also a use state and a packaging state. In the use state, the rotating tube and the support tube are circumferentially fixed, and the pedal is in a horizontal supporting posture to support the feet of the human body; in the packaging state, the rotating tube and the support tube rotate relative to each other, and the pedal is turned to be vertical and parallel to the two chair legs.

[0007] The pedal flips to be parallel to the two chair legs, that is, the pedal flips to be in the same plane as the two chair legs, so that the pedal no longer protrudes from the chair legs and will not occupy more space; since in the packaged state, the pedal flips to be vertical and in the same plane as the two chair legs, when packaging this seat in the packaged state, it seems that there is no footrest set on this seat, and the footrest is retracted between the two chair legs, reducing the complexity of packaging and also reducing the packaging and transportation costs; while in the use state, the footrest can remain horizontal and protrude forward from the chair legs to reasonably and comfortably support the child's feet.

[0008] Preferably, the rotating tube and the supporting tube are round tubes. When both the rotating tube and the supporting tube are round tubes, it is beneficial for the flipping of the rotating tube and the supporting tube, so that the pedal flips accordingly, and further enables the pedal to be between the two chair legs and parallel to the two chair legs or in the same plane as the two chair legs in the packaged state to save packaging and transportation costs.

[0009] Preferably, a limiting sliding groove is provided on the rotating tube, and a detachable limiting sliding member is provided on the supporting tube; in the use state, the limiting sliding member is located in the limiting sliding groove and is configured to prevent the rotating tube and the supporting tube from rotating; in the packaged state, the limiting sliding member is detached from the supporting tube, and the rotating tube can rotate relative to the supporting tube. When both the rotating tube and the supporting tube are round tubes, they can rotate relative to each other, although it is beneficial to flip the pedal between the two chair legs during packaging to save packaging and transportation costs, but in the supporting state, the pedal will rotate with the rotating tube and cannot achieve stable support. Therefore, a limiting sliding groove and a limiting sliding member are respectively provided on the rotating tube and the supporting tube. After packaging and transportation, they limit the rotating tube and the supporting tube, so that the pedal will no longer flip, thus enabling the pedal to stably support the human feet; in addition, the limiting sliding member is a screw that can be screwed, and tightening the screw can also lock the telescoping of the rotating tube and the supporting tube.

[0010] Preferably, the two chair legs incline forward and outward from top to bottom, there are two supporting tubes, and the two supporting tubes are arranged facing each other; the supporting tubes are arranged to be liftable on the chair legs. In the use state, when the pedal is lifted or lowered, the rotating tube and the supporting tube can telescopically adapt. The telescopic movement of the rotating tube and the supporting tube can adapt to the change in the distance between the chair legs, and even if a pedal is provided between the above-mentioned outward-inclined chair legs, the lifting and lowering of the pedal can be realized.

[0011] Preferably, a locking mechanism is further included, and the locking mechanism is sleeved on the chair leg; each supporting tube is fixedly connected to a locking mechanism, and the locking mechanism is configured to selectively lock or unlock with the chair leg, and when the locking mechanism is unlocked from the chair leg, the pedal can be lifted or lowered, and the rotating tube and the supporting tube can telescopically adapt. The locking mechanism is used to lock or unlock the lifting and lowering function of the pedal and can provide the ability for the pedal to support the feet when locked.

[0012] Preferably, the chair leg includes a fixed part and a movable part sleeved on the fixed part. The fixed part is configured to be fixedly connected to the seat. The movable part is threadedly connected to the fixed part and is arranged to be lifted and lowered on the fixed part. The movable part is a frustum of a cone, and the diameter of the movable part gradually increases from top to bottom. For the chair leg with such a changing diameter in the shape of a frustum of a cone, the locking mechanism can also lock or unlock with the chair leg at different diameters. That is, the greatest characteristic of the locking mechanism is that it will not be unable to lock due to the change in the diameter of the chair leg. At different diameter positions of the chair leg, the locking mechanism can achieve the functions of locking and unlocking. Moreover, the locking mechanism enables the telescoping of the movable part and the fixed part and the lifting of the pedal not to interfere with each other, and both can proceed smoothly, greatly increasing the functionality of the seat.

[0013] Preferably, the locking mechanism includes a sleeve and a movable piece arranged in the sleeve. An installation seat extends from the sleeve towards the telescopic assembly. The end of the telescopic assembly is inserted into the installation seat and fixedly connected to the installation seat. A knob and a locking piece controlled to retract by the knob are also provided on the sleeve. The knob is arranged outside the sleeve. One end of the locking piece is fixedly connected to the knob, and the other end of the locking piece abuts against the movable piece. The knob is configured to control the locking piece to move towards the movable piece, so that the movable piece presses against the chair leg and locks with the chair leg, or control the locking piece to move away from the movable piece, and the movable piece releases the chair leg and unlocks with the chair leg. The locking piece is a screw, which is threadedly connected to the sleeve, and the knob is turned to control the retraction of the locking piece. The retraction of the locking piece can control the movable piece to press against or release the chair leg, so as to achieve the function of the locking mechanism.

[0014] Preferably, a gap-blocking part is further provided on the movable piece. The gap-blocking part protrudes upwards from the sleeve, and the gap-blocking part extends outwards along the diameter direction of the sleeve. The gap-blocking part is used to block the gap generated between the movable piece and the sleeve after the movable piece moves inwards radially, improving the appearance and making it more plump. There can be two gap-blocking parts, which respectively protrude from the sleeve upwards and downwards.

[0015] Preferably, the movable piece has elasticity. Doing so is convenient for installing the movable piece into the sleeve on the one hand, and on the other hand, it can make the movable piece fit the frustum-shaped chair leg, that is, adapt to the changing diameter of the chair leg, increase the contact area, increase the friction force, and also make the gap between the movable piece and the chair leg smaller and more beautiful.

[0016] Preferably, limiting convex points are provided on the movable piece, and corresponding limiting grooves are provided on the inner wall of the sleeve. The movable piece is installed in the sleeve and the limiting convex points are located in the limiting grooves. To prevent the relative movement or rotation of the movable piece and the sleeve.

[0017] The design starting point, concept and beneficial effects of the present utility model adopting the above technical solutions are:

[0018] The pedal flips to be parallel to the two chair legs, that is, the pedal flips to be in the same plane as the two chair legs, so that the pedal no longer protrudes from the chair legs and does not occupy more space. Since in the packaged state, the pedal flips to be vertical and in the same plane as the two chair legs, when packaging the seat in the packaged state, it seems that there is no footrest on the seat, and the footrest is retracted between the two chair legs, reducing the complexity of packaging and also reducing the cost of packaging and transportation. In the use state, the footrest can keep horizontal and protrude forward from the chair legs to reasonably and comfortably support the child's feet. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0030] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0031] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0032] In the description of the present invention, the terms "first", "second", "third", etc. are only used for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0033] The specific implementation manners of the present invention are as follows:

[0034] As Figure 1 、 7 shown, the present invention provides a seat that is conducive to packaging and transportation, including a pedal 1, a rotating tube 22, a support tube 21, and two chair legs 4 arranged at intervals left and right. The support tube 21 is horizontally arranged on the chair legs 4, the rotating tube 22 is sleeved on the support tube 21, the pedal 1 is fixedly connected to the rotating tube 22, and both the pedal 1 and the rotating tube 22 are located between the two chair legs 4; it also has a use state and a packaging state. In the use state, the rotating tube 22 and the support tube 21 are circumferentially fixed, and the pedal 1 is in a horizontal support posture to support the feet of a person; in the packaging state, the rotating tube 22 and the support tube 21 rotate relative to each other, and the pedal 1 flips to be vertical and parallel to the two chair legs 4.

[0035] The pedal 1 flips to be parallel to the two chair legs 4, that is, the pedal 1 flips to be in the same plane as the two chair legs 4, so that the pedal 1 no longer protrudes from the chair legs 4 and will not occupy more space; since in the packaging state, the pedal 1 flips to be vertical and in the same plane as the two chair legs 4, when packaging the seat in the packaging state, it seems that there is no footrest on the seat, and the footrest is retracted between the two chair legs 4, reducing the complexity of packaging and also reducing the cost of packaging and transportation; while in the use state, the footrest can remain horizontal and protrude in front of the chair legs 4 to reasonably and comfortably support the feet of a child.

[0036] In this embodiment, the rotating tube 22 and the supporting tube 21 are round tubes, which is conducive to the flipping of the rotating tube 22 and the supporting tube 21, so that the pedal 1 is flipped accordingly, and then the pedal 1 can be located between the two chair legs 4 in the packaged state and parallel to the two chair legs 4 or in the same plane as the two chair legs 4, so as to save packaging and transportation costs.

[0037] like Figure 4 , 7 As shown, a limited sliding groove 11 is provided on the rotating tube 22, and a detachable limited sliding member 12 is provided on the supporting tube 21; in the use state, the limited sliding member 12 is located in the limited sliding groove 11, and is configured to prevent the rotating tube 22 and the supporting tube 21 from rotating; in the packaging state, the limited sliding member 12 is removed from the supporting tube 21, and the rotating tube 22 can rotate relative to the supporting tube 21; when the rotating tube 22 and the supporting tube 21 are both round tubes, the rotating tube 22 and the supporting tube 21 can rotate relative to each other, which is beneficial for turning the pedal 1 to the two sides when packaging. The chair legs 4 are interlaced to save packaging and transportation costs, but the pedal 1 will rotate with the rotating tube 22 in the supported state, and stable support cannot be achieved. Therefore, a limiting sliding groove 11 and a limiting sliding member 12 are respectively set on the rotating tube 22 and the supporting tube 21. After packaging and transportation, the two limit the rotating tube 22 and the supporting tube 21, so that the pedal 1 will no longer flip over, thereby allowing the pedal 1 to stably support the human feet; in addition, the limiting sliding member 12 is a screw that can be screwed, and tightening the screw can also lock the extension and retraction of the rotating tube 22 and the supporting tube 21.

[0038] In addition, if Figures 1-10 As shown, the pedal 1 of the seat can also be raised and lowered and the chair leg 4 can also be extended and retracted. Specifically, the chair leg 4 is inclined from top to bottom, forward and outward; the chair leg 4 includes a fixed portion 41 and a movable portion 42, the movable portion 42 is sleeved on the lower end of the fixed portion 41 and the movable portion 42 is raised and lowered on the fixed portion 41; the fixed portion 41 is fixedly connected to the seat of the chair, the fixed portion 41 is a pipe fitting, and the movable portion 42 is a pipe fitting sleeved outside the fixed portion 41, and the movable portion 42 is located at the lower end of the fixed portion 41 and in contact with the ground; the fixed portion 41 and the movable portion 42 are connected by a threaded connection, and the movable portion 42 and the fixed portion 41 can be extended and retracted by rotating the movable portion 42, so as to realize the lifting and lowering of the chair leg 4 and the seat, thereby adapting to the body shapes of children of different age groups.

[0039] In the use state, the seat also has a support state and an adjustment state. There are two support tubes 21, and both of the two support tubes 21 are partially inserted into the rotating tube 22. Locking mechanisms 3 are installed at the ends of the support tubes 21 exposed from the rotating tube 22. The locking mechanisms 3 are sleeved on the chair legs 4 and adapt to different diameters at different positions of the chair legs 4 and selectively lock or unlock with the chair legs 4. The support tubes 21 and the rotating tube 22 can expand and contract as the distance between the two chair legs 4 changes during lifting, and when expanding and contracting, the limit sliding members 12 slide in the limit sliding grooves 11. The locking mechanisms 3 are sleeved on the movable parts 42. In the support state, the locking components lock with the movable parts 42. In the adjustment state, the locking components unlock from the movable parts 42 and the locking components can move up and down relative to the fixed parts 41, that is, the pedal 1 can move up and down, and the support tubes 21 and the rotating tube 22 will adaptively expand and contract.

[0040] In the adjustment state, rotating the movable part 42 and the lifting pedal 1 will not conflict and interfere with each other. Further, the movable part 42 is frustum-shaped, and the diameter of the movable part 42 gradually increases from top to bottom. Such chair legs 4 are more beautiful, and it is convenient to hold and rotate the movable part 42. Although the diameter of the movable part 42 changes, the locking mechanism 3 of the lifting footrest can adapt to the diameter change of the movable part 42, so that when the locking mechanism 3 locks with the movable part 42, it is more firm, and the bearing capacity of the pedal 1 is stronger.

[0041] The locking mechanism 3 can be a cam wrench or other similar mechanisms, or it can be realized by setting a counterbore in the chair leg 4 and using a pin on the locking mechanism 3 that can enter and leave the counterbore to lock and unlock. In this embodiment, as Figures 8-10 shown, the locking mechanism 3 includes a sleeve 31 and a movable piece 32 and a gasket 33 arranged in the sleeve 31. The movable piece 32 and the gasket 33 are both arc-shaped sheets and are respectively inserted into the sleeve 31. The movable piece 32 is away from the support tube 21, and the gasket 33 is close to the support tube 21. Limiting convex points are provided on both the movable piece 32 and the gasket 33, and corresponding limiting grooves are provided on the inner wall of the sleeve 31. After the movable piece 32 and the gasket 33 are inserted into the sleeve 31, the limiting convex points are located in the limiting grooves to prevent the movable piece 32 and the gasket 33 from moving or rotating relative to the sleeve 31.

[0042] On the sleeve 31, there is a mounting seat 5 extending towards the support tube 21. The end of the support tube 21 away from the rotating tube 22 is inserted into the mounting seat 5 and fixedly connected to the mounting seat 5 by screws. A knob 6 and a locking member 7 controlled to retract by the knob 6 are also provided on the sleeve 31. The knob 6 is arranged on the outer side of the sleeve 31 and away from the support tube 21. One end of the locking member 7 is fixedly connected to the knob 6, and the other end of the locking member 7 abuts against the movable piece 32. The knob 6 is configured to control the locking member 7 to move towards the movable piece 32 to press the chair leg 4 by the movable piece 32, or to control the locking member 7 to move away from the movable piece 32 to release the chair leg 4 by the movable piece 32. In the support state, the movable piece 32 presses the chair leg 4 so that the locking mechanism 3 stays in the current position. In the adjustment state, the movable piece 32 releases the chair leg 4 so that the locking mechanism 3 can move up and down on the chair leg 4. The locking member 7 is a screw threadedly connected to the sleeve 31, and turning the knob 6 controls the retraction of the locking member 7. The retraction of the locking member 7 can control the movable piece 32 to press or release the chair leg 4, thereby realizing the function of the locking mechanism 3.

[0043] Furthermore, a slot covering part 8 is also provided on the sleeve 31 and the movable piece 32. The slot covering part 8 protrudes upward from the sleeve 31 and extends outward along the diameter direction of the sleeve 31. The slot covering part 8 is used to cover the gap generated between the movable piece 32 and the sleeve 31 after the movable piece 32 moves radially inward, improving the appearance and making it more plump. There can be two slot covering parts 8, respectively protruding upward and downward from the sleeve 31. Both the movable piece 32 and the gasket 33 are elastic. On the one hand, this facilitates the installation of the movable piece 32 and the gasket 33 into the sleeve 31. On the other hand, it enables the movable piece 32 and the gasket 33 to fit the frustum-shaped chair leg 4, that is, to adapt to the changing diameter of the chair leg 4, increase the contact area, increase the friction force, and make the gap between the movable piece 32 and the chair leg 4 smaller and more beautiful. Compared with the direct contact between the sleeve 31 and the chair leg 4, the contact between the movable piece 32, the gasket 33 and the chair leg 4 can be closer. Firstly, the gap is removed, and secondly, the friction force is increased, ensuring the stability when the locking mechanism 3 is locked with the chair leg 4 and improving the supporting capacity of the pedal 1.

[0044] Furthermore, as Figures 2-6 shown; the rotating tube 22 is fixedly connected to the pedal 1, and the two locking mechanisms 3 are respectively fixedly connected to the two support tubes 21. When the support tube 21 is configured to move up and down, the support tube 21 slides in the rotating tube 22 to adapt to the change in the distance between the two chair legs 4. The way for the support tube 21 and the rotating tube 22 to achieve telescoping is the telescoping between the rotating tube 22 and the two support tubes 21. When the pedal 1 moves up and down, the support tube 21 and the rotating tube 22 will not only move up and down together but also generate relative sliding. At the position where the distance between the chair legs 4 is smaller, the support tube 21 enters the rotating tube 22 more. At the position where the distance between the chair legs 4 is larger, the support tube 21 will protrude from the rotating tube 22 more, thereby realizing the adaptation to the change in the distance between the chair legs 4.
