[0045] See Figure 1A swing dining chair is provided, including a support frame 100, a swing frame 200, and a seat 300. The support frame 100 has a structure including, but not limited to, two oppositely arranged side frames, and the swing frame 200 is arranged between the two side frames. In one embodiment, the side frame includes an inclined support rod, and the support frame 100 also includes a base frame connected to the bottom of the two side frames.

[0046] like Figure 2 As shown, in another embodiment, the support frame 100 includes a first leg assembly 110 and a second leg assembly 120 rotatably connected by a joint 130. The first leg assembly 110 is inclined backward from bottom to top, and the second leg assembly 120 is inclined backward from top to bottom. The first leg assembly 110 includes two oppositely arranged first leg rods 111, and the second leg assembly 120 includes two oppositely arranged second leg rods 121. The tops of the first leg rods 111 and the second leg rods 121 on the same side are hinged by the joint 130 to form a side frame.

[0047] like Figures 1-8 As shown, the seat 300 is mounted on the swing frame 200, which is rotatably mounted on the support frame 100 about a first horizontal axis, giving the dining chair a first usage mode and a second usage mode. The first horizontal axis is the direction of the two side frames, also known as the left-right direction. In one embodiment, the swing frame 200 includes two swing arms 210 arranged left and right, and a crossbar 220 connected between the two swing arms 210. The tops of the two swing arms 210 are rotatably connected to the joints 130, and the crossbar 220 is connected to the bottoms of the two swing arms 210.

[0048] like Figure 4 As shown, the seat 300 includes side panels 310 arranged on the left and right, a seat cushion 320, a backrest 330, and a tray 340. The side panels 310, seat cushion 320, backrest 330, and tray 340 together form a space for a child to sit in. The backrest 330 and seat cushion 320 can rotate and cooperate, and the angle of the backrest 330 relative to the seat cushion 320 is adjustable. Figure 5 and Figure 7 As shown, the side rails 310 and the swing arm 210 are slidably engaged and height-adjustable. In one embodiment, the tray 340 is detachably connected to the two side rails 310 to facilitate children's access to and from the seating space.

[0049] See also Figure 4 In one embodiment, the side rail 310 includes a main body 311 and an adjustment seat 312 that rotatably engages with the main body 311. The adjustment seat 312 and the rocker arm 210 are slidably engaged to achieve height adjustment of the seat 300. An angle adjustment mechanism is provided between the adjustment seat 312 and the main body 311.

[0050] like Figure 5 and Figure 7As shown, in the first usage mode, the swing frame 200 and the support frame 100 are combined to fix the seat 300. For example, in the figure, the swing frame 200 is combined with the first foot assembly 110, at which time the child can carry out activities such as eating normally.

[0051] like Figure 8 As shown, in the second usage mode, the swing frame 200 and the support frame 100 are separated, and the seat 300 can swing along the dotted line in the figure with the swing frame 200, thus functioning as a swing for children's entertainment. To facilitate caregivers looking after children, in one embodiment, the swing chair includes a drive mechanism mounted on the support frame 100, which drives the swing frame 200 to swing in the second usage mode. For example, the drive mechanism is located within the joint 130 and includes a motor as a power source.

[0052] Preferably, in the second usage mode, the seat 300 slides relative to the rocker arm 210 and is adjusted to the lowest position to lower the center of gravity and make swaying safer. The backrest 330 is adjusted to tilt, specifically to maximize the angle between the backrest 330 and the seat cushion 320.

[0053] like Figures 9-14 As shown, to facilitate switching between the two modes, the swing chair also includes a locking element 400 and a resilient return element 500. The locking element 400 is used to lock the swing frame 200 so that the chair is in the first usage mode. The locking element 400 is movable and has a locked position and an unlocked position. The resilient return element 500 acts directly or indirectly on the locking element 400, causing it to tend to move from the unlocked position to the locked position.

[0054] In actual locking operations, such as Figure 12 and Figure 13 As shown, during the process of switching the dining chair from the second usage mode to the first usage mode, the locking member 400 is subjected to an external force other than human intervention (such as touching other components), which drives the locking member 400 along... Figure 13 The dashed arrow in the image indicates that the device moves from the locked position to the unlocked position, simultaneously compressing the elastic reset element 500. Figure 14 As shown, when the swing frame 200 swings to its position, the elastic reset member 500 drives the locking member 400 to return to the locked position, and the locking member 400 locks the swing frame 200, so that the dining chair remains in the first usage mode. The entire locking process only requires manual control of the swing frame 200 to rotate and move closer to the first foot assembly 110, and wait for the locking member 400 to lock automatically, which is convenient for locking operation.

[0055] When switching the dining chair from the second usage mode to the first usage mode: simply manually drive the locking device 400 to the release position.

[0056] like Figures 1-3In one embodiment, the locking member 400 is movably mounted on one of the swing frame 200 and the support frame 100, while the other is provided with a locking part 140 that cooperates with the locking member 400. In the figures, the locking member 400 is rotatably mounted on the swing arm 210 about a second horizontal axis, which is parallel to and in the same direction as the first horizontal axis. Furthermore, the locking member 400 is rotatably connected to the bottom of the swing arm 210 and is located on the outer side of the axial direction, thereby maximizing the swing amplitude of the swing frame 200.

[0057] Combined Figures 11-14 A locking member 150 is fitted onto the first foot rod 111. A locking block, serving as a locking part 140, protrudes from the locking member 150. The locking member 400 is provided with a locking groove 410 that matches the locking block. One radial side of the locking groove 410 is open to allow the locking block to enter the locking groove 410. At least one of the locking member 400 and the locking part 140 is provided with a first inclined surface that guides the locking member 400 to move from the locked position to the unlocked position. In the figure, the locking block and the locking member 400 are provided with mutually cooperating first inclined surfaces. The two ends of the first inclined surface 141b of the locking member 400 extend to the outer peripheral surface of the locking member 400 and the locking groove 410, respectively.

[0058] When the dining chair switches from the second usage mode to the first usage mode, the first inclined surface 141a of the locking block and the first inclined surface 141b of the locking member 400 abut and press against each other, driving the locking member 400 to move from the locked position to the unlocked position. After the swing frame 200 swings into place and the lock groove 410 aligns with the locking block, the elastic reset member 500 drives the locking member 400 to reset, and the locking block enters the lock groove 410, completing the locking operation.

[0059] like Figure 11 As shown, the locking member 400 includes a connecting part 401 that is hinged to the swing arm 210, a joint part 402 with a locking groove 410, and an extension part 403 that connects the two joint parts 402 and the connecting part 401. When viewed along the axial direction, the extension part 403 and the joint part 402 extend out of the swing frame 200. The extension part 403 can be used as an operating part during the unlocking operation.

[0060] To prevent accidental locking during swinging, such as Figure 15 As shown, in one embodiment, the locking member 400 has a clearance position to avoid locking the swing frame 200. In the figure, viewed axially and in the clearance position, the locking member 400 coincides with the swing frame 200, resulting in a clean appearance and maximizing the swing amplitude of the swing frame 200.

[0061] like Figures 9-11As shown, in one embodiment, the swing chair also includes a positioning member 600 that engages with the locking member 400 to hold it in an abdication position. In the illustration, the positioning member 600 is slidably mounted on the swing frame 200 along a second horizontal axis. The locking member 400 is provided with a second inclined surface 420 to guide the movement of the positioning member 600. The second inclined surface 420 has a higher position 421 and a lower position 422 (the height direction is based on the second horizontal axis). The higher position 421 is provided with a positioning groove 423 that mates with the positioning member 600. The second inclined surface 420 is arranged circumferentially and has three sets. The positioning member 600 is cylindrical, and three positioning blocks 610 are arranged circumferentially and mate with the positioning grooves 423. The two circumferential sides of the positioning blocks 610 are arc surfaces. The elastic reset member 500 is a cylindrical spring that abuts against the positioning member 600 to achieve an indirect effect of the elastic reset member 500 on the locking member 400.

[0062] In practical use: When the locking member 400 is manually rotated in the first direction, the positioning member 600 slides under the guidance of the second inclined surface 420 until the positioning block 610 aligns with and engages with the positioning groove 423, at which point the locking member 400 switches to the clearance position. When the locking member 400 is manually rotated in the second direction, the positioning block 610 disengages from the positioning groove 423 and abuts against the second inclined surface 420 under the action of the elastic reset member 500, at which point the locking member 400 can then automatically switch to the locking position.

[0063] During the locking operation, when the locking member 400 switches from the locked position to the unlocked position, the second inclined surface 420 of the locking member 400 abuts against the positioning block 610, driving the positioning member 600 to slide, while compressing the elastic reset member 500. After the swing frame 200 swings to its position, the elastic reset member 500 resets, driving the positioning member 600 to slide and abut against the second inclined surface 420, causing the locking member 400 to rotate to the locked position.

[0064] In this application, when the swing dining chair is switched from the second usage mode to the first usage mode, the locking part first switches from the locked position to the unlocked position. After the swing frame is in place, the locking part resets to the locked position to complete the locking operation. The entire process only requires one hand to control the swing frame, without the need to operate any other buttons, making it convenient to operate.

[0065] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0066] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are quite specific and detailed. However, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
