Abstract
Description
[Technical field]
[0001] The present invention relates to a transportation device, and more particularly to a transportation device that can prevent a seat back from affecting the folding of the transportation device. [Background technology]
[0002] A stroller is a tool for parents to carry their babies or children when going shopping. Currently, various foldable strollers are known for easy storage and carrying. Referring to Figs. 1 and 2, Fig. 1 is a side view of a stroller 1 of the prior art, and Fig. 2 is a side view of the stroller 1 shown in Fig. 1 in a folded state. As shown in Figs. 1 and 2, the stroller 1 includes a handle 10, rear legs 12, front legs 14, a seat 16, handrails 18, and a backrest 20. The handle 10, rear legs 12, and front legs 14 can be folded or unfolded relative to each other to drive the seat 16, handrails 18, and backrest 20 to fold or unfold. As shown in Fig. 2, when the handle 10, rear legs 12, and front legs 14 are folded relative to each other, the seat 16 and handrails 18 are both rotated upwards, and the backrest 20 is rotated downwards. If the backrest 20 is too long, the backrest 20 will come into contact with the ground when the stroller 1 is folded. The length of the backrest 20 is limited because the backrest 20 not only affects the folding of the stroller 1 but also easily gets dirty. Furthermore, the seat 16 and the handrails 18 rotate upward, which increases the length of the stroller 1 when folded. Therefore, this is not beneficial for storing or carrying the stroller 1. Summary of the Invention [Problem to be solved by the invention]
[0003] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to solve the above problems and provide a transportation device that can prevent the backrest from affecting the folding of the transportation device. [Means for solving the problem]
[0004] This is achieved by a transport device as claimed in the independent claims. The dependent claims relate to corresponding further developments and improvements.
[0005] As will become more apparent from the following detailed description, the claimed transportation device includes a handle, rear legs, front legs, a seat, and handrails. The front legs are pivotally connected to the rear legs. The seat is pivotally connected to the handle, rear legs, and front legs. The handrails are pivotally connected to the handle. The handle, rear legs, and front legs fold or unfold relative to one another to actuate the seat and handrails to fold or unfold. After the handrails are folded, the front side of the handrails is lower than the rear side of the handrails.
[0006] Preferably, the transport device further comprises a fixing member, a first seat connecting member and a second seat connecting member. The fixing member is disposed at the rear of the seat and connected to an end of the handle. The first seat connecting member is pivotally connected to the seat and the fixing member such that the seat is pivotally connected to the handle. The second seat connecting member is pivotally connected to the seat and the rear legs such that the seat is pivotally connected to the rear legs. When the handle, the rear legs and the front legs are folded together, the fixing member and the rear legs rotate the rear side of the seat in a direction opposite to the ground by the first seat connecting member and the second seat connecting member, respectively. When the handle, the rear legs and the front legs are unfolded together, the fixing member and the rear legs drive the rear side of the seat to be positioned toward the ground by the first seat connecting member and the second seat connecting member, respectively.
[0007] Preferably, when the handle, rear legs and front legs are folded together, they rotate the front side of the handrail downwards in a rearward direction.
[0008] Preferably, the transport device further includes a lower leg rest pivotally connected to the front side of the seat.
[0009] Preferably, the transport device further comprises a first handrail connecting member and a second handrail connecting member. The first handrail connecting member is pivotally connected to the handrail and the second handrail connecting member. The second handrail connecting member is fixed to the rear leg. When the handle, the rear leg and the front leg are folded and unfolded relative to each other, the rear leg drives the handrail to fold and unfold by the first handrail connecting member and the second handrail connecting member.
[0010] Preferably, the transport device further comprises a first handrail connecting member, the first handrail connecting member being pivotally connected to the handrail and the rear leg, the rear leg driving the handrail to fold or unfold by the first handrail connecting member when the handle, the rear leg and the front leg are folded or unfolded relative to each other.
[0011] Preferably, the transport device further comprises a backrest and a backrest rotation base. The backrest is pivotally connected to the backrest rotation base.
[0012] Preferably, the transport device further includes a first backrest connecting member and a second backrest connecting member. The first backrest connecting member is pivotally connected to the backrest rotation base and the handle. The second backrest connecting member is pivotally connected to the fixed member, the seat and the backrest rotation base. When the handle, the rear legs and the front legs are folded or unfolded relative to each other, the handle drives the first backrest connecting member and the second backrest connecting member to fold or unfold the backrest.
[0013] Preferably, after the seat is folded, the front side of the seat is lower than the rear side of the seat.
[0014] Preferably, the transport device further comprises a backrest disposed behind the seat. When the handle, the rear legs and the front legs are folded together, the rotation directions of the seat and the backrest are opposite.
[0015] Preferably, when the handle, rear legs and front legs are folded together, the rotational directions of the seat and handrails are opposite.
[0016] When the transportation device of the present invention is folded, the handle, the rear legs and the front legs are folded or unfolded relative to each other to drive the seat and the handrail to fold or unfold. After the handrail is folded, the front side of the handrail is lower than the rear side of the handrail. Therefore, after the transportation device of the present invention is folded, the handrail rotates downwards so that the front side of the handrail is lower than the rear side of the handrail, thereby reducing the height of the folded transportation device. Therefore, it is advantageous for storing and carrying the transportation device.
[0017] In the following the invention will be further explained by way of example of embodiment with reference to the attached drawings, in which: [Brief description of the drawings]

[0019] Referring to Figures 3 to 8, Figure 3 is an oblique view showing a transport device 3 according to one embodiment of the present invention, Figure 4 is a side view of the transport device 3 shown in Figure 3, Figure 5 is an oblique view showing the transport device 3 shown in Figure 3 folded in half, Figure 6 is a side view of the transport device 3 shown in Figure 5, Figure 7 is an oblique view showing the transport device 3 shown in Figure 3 folded, and Figure 8 is a side view of the transport device 3 shown in Figure 7.
[0020] As shown in Figures 3 to 8, the transport device 3 of the present invention includes a handle 30, a fixing member 32, rear legs 34, front legs 36, a seat 38, a first seat connecting member 40, a second seat connecting member 42, a lower leg rest 44, a handrail 46, a first handrail connecting member 48, and a second handrail connecting member 50. The transport device 3 may be a stroller or other device used for transportation. Note that the structure of the transport device 3 of the present invention is substantially symmetrical, and the technical features of the present invention will be described below with respect to the structure viewed from one direction.
[0021] 3 to 8, in this embodiment, the handle 30 may include an upper handle 300, a first lower handle 302, and a second lower handle 304. The first lower handle 302 and the second lower handle 304 are pivotally connected to the upper handle 300 such that the upper handle 300, the first lower handle 302, and the second lower handle 304 can rotate relative to each other to fold or unfold. The transport device 3 may further include a folding operation member 52 and a locking mechanism 54. The folding operation member 52 may be disposed on the upper handle 300. A user can fold the transport device 3 by operating the folding operation member 52. The locking mechanism 54 may be disposed on a pivot joint between the upper handle 300 and the second lower handle 304, and the locking mechanism 54 is used to lock or unlock the upper handle 300 and the second lower handle 304.
[0022] As shown in FIG. 3 and FIG. 4, the fixing member 32 is disposed on the rear side 382 of the seat 38 and is connected to an end of the second lower handle 304 of the handle 30. In this embodiment, the rear leg 34 may include a connecting member 340. The front leg 36 and the first lower handle 302 of the handle 30 are pivotally connected to the opposite side of the connecting member 340 of the rear leg 34, so that the front leg 36 and the first lower handle 302 of the handle 30 can rotate together so as to be folded and unfolded relative to the rear leg 34. The seat 38 is pivotally connected to the front leg 36. Both ends of the first seat connecting member 40 are pivotally connected to the seat 38 and the fixing member 32. Both ends of the second seat connecting member 42 are pivotally connected to the seat 38 and the rear leg 34. In this embodiment, the first seat connecting member 40 and the second seat connecting member 42 may be, but are not limited to, iron plates.
[0023] As shown in FIGS. 3, 5, and 7, the seat 38 has a front side 380 and a rear side 382. The lower leg rest 44 is pivotally connected to the front side 380 of the seat 38 such that the lower leg rest 44 can rotate relative to the seat 38 to adjust the angle between the lower leg rest 44 and the seat 38. In addition, the transport device 3 may further include a backrest 56 (as shown in FIG. 8). Generally, the backrest 56 is disposed on the rear side 382 of the seat 38. Thus, the rear side 382 of the seat 38 is the transition between the seat 38 and the backrest 56. In this embodiment, the handrail 46 may be pivotally connected to the first lower handle 302 of the handle 30 by a pivot 460, and the handrail 46 can rotate relative to the first lower handle 302 of the handle 30 to adjust the angle between the handrail 46 and the first lower handle 302. The second handrail connecting member 50 is fixed to the connecting member 340 of the rear leg 34. One end of the first handrail linking member 48 is pivotally connected to the handrail 46 by a pivot 462, and the other end of the first handrail linking member 48 is pivotally connected to a second handrail linking member 50. In this embodiment, the first handrail linking member 48 and the second handrail linking member 50 may be, but are not limited to, iron plates.
[0024] As shown in Figures 3 to 8, the handle 30, the rear legs 34, and the front legs 36 can be folded or unfolded relative to one another to fold or unfold the seat 38 and the handrails 46. To further explain, when the handle 30, the rear legs 34, and the front legs 36 are folded relative to one another, the fixing member 32 and the rear legs 34 drive the seat 38 to fold or unfold by the first seat connecting member 40 and the second seat connecting member 42, respectively. As shown in Figures 7 and 8, when the handle 30, the rear legs 34, and the front legs 36 are folded relative to one another, the fixing member 32 and the rear legs 34 drive the rear surface 382 of the seat 38 to rotate in a direction away from the ground (i.e., in the direction of arrow A1) by the first seat connecting member 40 and the second seat connecting member, respectively. Therefore, after the seat 38 is folded, the seat 38 rotates downward in the direction of the arrow A1, so that the front side 380 of the seat 38 is lower than the rear side 382 of the seat 38. As mentioned above, the rear side 382 of the seat 38 is the boundary between the seat 38 and the backrest 56. Therefore, in other words, after the seat 38 is folded, the boundary between the seat 38 and the backrest 56 moves to the uppermost position, and after the transportation device 3 is folded, the backrest 56 does not contact the ground. Therefore, the length of the backrest 56 can be increased according to actual requirements. Furthermore, when the handle 30, the rear leg 34 and the front leg 36 are deployed relative to each other, the fixing member 32 and the rear leg 34 respectively drive the rear surface 382 of the seat 38 to be positioned toward the ground (i.e., in the direction of the arrow A2) by the first seat connecting member 40 and the second seat connecting member 42.
[0025] As shown in Figures 3 to 8, when the handle 30, the rear legs 34 and the front legs 36 are folded or unfolded relative to each other, the rear legs 34 also drive the handrail 46 to fold or unfold by the first handrail connecting member 48 and the second handrail connecting member 50. As shown in Figures 7 and 8, after the transportation device 3 is folded, the seat 38 rotates downward in the direction of arrow A1, and the handrail 46 rotates downward in the direction of arrow A2, lowering the height of the folded transportation device 3. This is therefore advantageous for storage and carrying of the transportation device 3.
[0026] In addition, in other embodiments, the transportation device 3 may include only the first handrail connecting member 48 without including the second handrail connecting member 50. That is, the second handrail connecting member 50 may be omitted. When the transportation device 3 includes only the first handrail connecting member 48, both ends of the first handrail connecting member 48 may be pivotally connected to the handrail 46 and the rear leg 34. Therefore, when the handle 30, the rear leg 34, and the front leg 36 are folded or unfolded relative to each other, the rear leg 34 drives the handrail 46 by the first handrail connecting member 48 to be folded or unfolded.
[0027] Referring to Figures 9 to 16, Figure 9 is an oblique view showing a transportation device 3 according to another embodiment of the present invention, Figure 10 is an oblique view showing the transport device 3 shown in Figure 9 without the handle 30, rear legs 34 and front legs 36, Figure 11 is an oblique view of the transport device 3 shown in Figure 9 from another angle, Figure 12 is an oblique view of the transport device 3 shown in Figure 9 from another angle, Figure 13 is a side view of the transport device 3 shown in Figure 9, Figure 14 is a side view showing the transport device 3 shown in Figure 13 folded in half, Figure 15 is a side view showing the transport device 3 shown in Figure 13 in a folded state, and Figure 16 is an oblique view of the transport device 3 shown in Figure 15.
[0028] As shown in Figures 9 to 16, the transport device 3 may further include a backrest rotation base 58, a first backrest connecting member 60, and a second backrest connecting member 62. The backrest 56 is pivotally connected to the backrest rotation base 58 so that the backrest 56 can rotate relative to the backrest rotation base 58 to adjust the angle between the backrest 56 and the backrest rotation base 58. As shown in Figures 11 and 13, both ends of the first backrest connecting member 60 are pivotally connected to the backrest rotation base 58 and the second lower handle 304 of the handle 30. The second backrest connecting member 62 is pivotally connected to the fixed member 32, the seat 38, and the backrest rotation base 58. As shown in Figures 11 and 13, the lower end of the second backrest connecting member 62 is pivotally connected to the fixed member 32. As shown in Fig. 12 and Fig. 13, the upper end front side of the second backrest connecting member 62 is pivotally connected to the seat 38, and the middle part of the second backrest connecting member 62 is pivotally connected to the backrest rotation base 58. Therefore, when the handle 30, the rear leg 34, and the front leg 36 are folded or unfolded relative to each other, the handle 30 drives the backrest 56 to fold or unfold by the first backrest connecting member 60 and the second backrest connecting member 62. Note that Fig. 13 to Fig. 15 show the folding process when the backrest 56 is in an upright state. When the backrest 56 is in a reclining state, the backrest 56 pushes the rear leg 34 during the folding process, so that the backrest 56 is pushed to an upright position. In this embodiment, the first backrest connecting member 60 and the second backrest connecting member 62 may be, but are not limited to, iron plates.
[0029] As described above, when the transportation device of the present invention is folded, the handle, the rear legs and the front legs are folded or unfolded relative to each other to drive the seat and the handrail to fold or unfold. After the handrail is folded, the front side of the handrail is lower than the rear side of the handrail. Therefore, after the transportation device of the present invention is folded, the handrail rotates downwards so that the front side of the handrail is lower than the rear side of the handrail, thereby reducing the height of the folded transportation device. Therefore, it is advantageous for storing and carrying the transportation device.
[0030] The above is merely a preferred embodiment of the present invention, and the scope of protection of the present invention is not limited to the above description. Any modifications or replacements within the technical scope disclosed by the present specification are included in the scope of protection of the present invention.
