As shown in fig. 1, the passenger device 1 of the present invention includes a frame 10 and a seat 12. The passenger device 1 may be a baby stroller or other device for carrying. The seat 12 is provided on the frame 10. The frame 10 may be stowed or deployed in conjunction with the seat 12. In another embodiment, the seat 12 is removably disposed on the frame 10. At this time, the seat 12 may be removed from the frame 10 and then individually folded or unfolded. As shown in fig. 1 and 2, the seat 12 is in a deployed state. As shown in fig. 3, the seat 12 is in a stowed position. The passenger device 1 and the seat 12 of the present invention are configured to be substantially bilaterally symmetrical, and the technical features of the present invention will be described below with reference to a one-sided configuration.
In some embodiments, the seat 12 is removably mounted to the passenger device, but the invention is not limited thereto.
As shown in fig. 1-5, the seat 12 includes a support base 120, a backrest 122, a lower leg rest 124, and a locking member 126. The support base 120 is coupled to the frame 10 to mount the seat 12 to the frame 10. The backrest 122 is connected to the support base 120, and the calf rest 124 is pivotally connected to the support base 120. In this embodiment, the backrest 122 and the lower leg rest 124 may be U-shaped pipe, but not limited thereto. In practice, the backrest 122 and the calf rest 124 can be covered by seat cloth to form a seating area for seating. In another embodiment, the seat 12 may be supplemented with other support or reinforcement structures (e.g., a seat pan) depending on the application.
As shown in fig. 4, 5 and 7, the support base 120 includes a first pivot portion 1200, and the lower leg rest 124 includes a second pivot portion 1240. The first pivot portion 1200 is inserted into the second pivot portion 1240, and the first pivot portion 1200 and the second pivot portion 1240 have corresponding holes for a pivot (not shown) to be inserted into, so that the calf rest 124 is pivoted to the support base 120.
As shown in fig. 4, 5 and 7, the locking member 126 is disposed between the support base 120 and the lower leg rest 124. In this embodiment, the lower leg rest 124 further includes a receiving slot 1242 and two engaging slots 1244a and 1244b, wherein the two engaging slots 1244a and 1244b are located at two sides of the receiving slot 1242, and the second pivot portion 1240 is located in the receiving slot 1242. In addition, the locking element 126 includes a through hole 1260 and two engaging portions 1262a, 1262b, wherein the two engaging portions 1262a, 1262b are located at two sides of the through hole 1260. As shown in fig. 5, the second pivot portion 1240 of the lower leg rest 124 is inserted into the through hole 1260 of the locking member 126, so that the locking member 126 is movably disposed in the accommodating groove 1242 of the lower leg rest 124. The locking member 126 is thereby movable relative to the calf rest 124 in the direction of double arrow A1 in fig. 5. The two engaging portions 1262a and 1262b of the locking piece 126 are engaged with the two engaging grooves 1244a and 1244b of the lower leg rest 124, respectively, so that the locking piece 126 can rotate together with the lower leg rest 124 in the direction of the double arrow A2 in fig. 5.
As shown in fig. 7, the seat 12 further includes a resilient member 128 disposed between the lower leg rest 124 and the locking member 126. In the present embodiment, the elastic member 128 may be a spring, but is not limited thereto. In addition, as shown in fig. 4 and fig. 6, the supporting base 120 further includes a driving inclined plane 1202 and a stopping portion 1204, wherein the height of the driving inclined plane 1202 is gradually increased from the engaging portion 1262b to the engaging portion 1262a, and the stopping portion 1204 is located at one end of the driving inclined plane 1202 corresponding to the engaging portion 1262 a.
When the calf back 124 is unfolded relative to the backrest 122 to the unfolded position shown in figures 1 and 2, the locking member 126 is in the locked position shown in figure 7. At this point, the locking member 126 will lock the calf back 124 in the unfolded position relative to the backrest 122. As shown in fig. 4, when the locking member 126 is in the locking position, the stopping portion 1204 of the supporting seat 120 stops the engaging portion 1262a of the locking member 126, so that the calf rest 124 cannot rotate further in the direction of arrow A3. Thereby, calf rest 124 is retained in the deployed position.
When the user wants to fold the seat 12, the user can rotate the lower leg rest 124 relative to the backrest 122 in the direction of arrow A4 in fig. 2. When the calf back 124 rotates relative to the backrest 122, the calf back 124 drives the lock member 126 to unlock, so that the calf back 124 can rotate relative to the backrest 122 to the folded position shown in fig. 3. Further, when lower leg rest 124 is rotated in the direction of arrow A4 relative to backrest 122 from the deployed position shown in FIG. 2, locking member 126 shown in FIG. 6 rotates with lower leg rest 124 in the direction of arrow A4. At this time, the driving inclined plane 1202 of the supporting seat 120 pushes the engaging portion 1262b of the locking member 126, so that the locking member 126 moves toward the calf rest 124 to drive the locking member 126 to unlock. Then, the locking member 126 will completely enter the receiving slot 1242 of the lower leg rest 124 to be at the unlocking position shown in fig. 8, so that the lower leg rest 124 can rotate relative to the backrest 122 to the folding position shown in fig. 3. Therefore, the seat 12 can be quickly folded by rotating the lower leg rest 124, and the folding seat is simple in structure and convenient to operate.
As shown in FIG. 8, when the lower leg rest 124 rotates to drive the locking member 126 to unlock, the locking member 126 moves toward the lower leg rest 124 to compress the elastic member 128. When the user wishes to unfold the seat 12, the user can rotate the lower leg rest 124 relative to the backrest 122 in the direction of arrow A3 in fig. 3. When the calf back 124 rotates relative to the backrest 122 from the stowed position shown in fig. 3 to the deployed position shown in fig. 2, the elastic force generated by the elastic member 128 shown in fig. 8 drives the locking member 126 to return toward the support base 120, so as to lock the calf back 124 in the deployed position relative to the backrest 122.
As shown in fig. 1-3 and 9, chair 12 may further include an armrest 130 pivotally connected to lower leg rest 124. Therefore, the armrests 130 can also rotate relative to the backrest 122 to be folded or unfolded. Preferably, armrest 130 is removably pivotally coupled to lower leg rest 124 such that armrest 130 is removable from seat 12 when not in use. As shown in fig. 10, lower leg rest 124 may include a guide slot 1246 and armrest 130 may include a guide post 1300. When the armrest 130 is pivoted to the lower leg rest 124, the guide post 1300 is inserted into the guide slot 1246. Therefore, when the lower leg rest 124 rotates relative to the backrest 122 to be folded or unfolded, the end of the guiding slot 1246 of the lower leg rest 124 pushes the guiding post of the armrest 130 to drive the armrest 130 to rotate relative to the backrest 122 to be folded or unfolded.
Therefore, according to the above technical solution, the seat and the passenger device of the present invention have at least the following advantages and benefits: the user can fold or unfold the chair only by rotating the crus rest. The invention can realize the rapid folding of the seat by the rotation of the crus rest by means of the matching of the locking piece and the driving inclined plane of the supporting seat, and has simple structure and convenient operation. In addition, if the chair is provided with the armrests, the user can synchronously fold or unfold the armrests only by rotating the crus rest. The seat of the invention does not need to be provided with a separate folding operation mechanism, thereby further reducing the manufacturing cost of the seat and the passenger device.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
