Best Mode for Carrying Out the Invention

[0018] In FIGS. 1 to 4, FIG. 1 is a perspective view showing a baby stroller 1 according to an embodiment of the present invention, FIG. 2 is a perspective view showing the state of the baby stroller 1 shown in FIG. 1 with the seat 14 removed, FIG. 3 is a perspective view showing the seat 14 shown in FIG. 1 as viewed from another perspective, and FIG. 4 is a cross-sectional view showing the assembled state of the seat 14 and the seat fixing base 12.

[0019] As shown in FIGS. 1 and 2, the baby stroller 1 includes a frame 10, a seat fixing base 12, and a seat 14. The seat fixing base 12 is disposed on the frame 10, and the seat 14 is detachably disposed on the seat fixing base 12. As shown in FIGS. 2 and 4, the seat fixing base 12 has an engaging structure 120. As shown in FIGS. 1, 3, and 4, the seat 14 includes an unlocking button 140 and a plurality of engaging members 142, and the unlocking button 140 abuts against the engaging members 142. In this embodiment, the seat 14 can include four engaging members 142, but the present invention is not limited thereto. The number of engaging members 142 can be determined according to actual applications.

[0020] As shown in FIG. 4, when the seat 14 is disposed on the seat fixing base 12, the engaging members 142 engage with the engaging structure 120 to restrain the seat 14 on the seat fixing base 12. When the user wants to remove the seat 14, the user can push the unlocking button 140 in the direction of arrow A1. When the unlocking button 140 is pushed, the engaging members 142 are moved in the direction of arrow A2 by the unlocking button 140. At this time, the engaging members 142 are disengaged from the engaging structure 120, and the seat 14 can be removed from the seat fixing base 12. In this embodiment, the moving direction of each engaging member 142 (i.e., the direction of arrow A2) is orthogonal to the pressing direction of the unlocking button 140 (i.e., the direction of arrow A1), but the present invention is not limited thereto.

[0021] As shown in FIG. 2, the engaging structure 120 of the seat fixing base 12 is a ring-shaped recess. Therefore, the engaging member 142 engages with the ring-shaped recess (i.e., the engaging structure 120) to rotatably restrain the seat 14 on the seat fixing base 12. To explain further, since the engaging member 142 can move freely within the ring-shaped recess, the seat 14 can rotate 360 degrees with respect to the seat fixing base 12. At the same time, because the engaging member 142 engages with the engaging structure 120, the seat 14 is restrained by the seat fixing base 12 while rotating, and the rotation of the seat 14 becomes more stable.

[0022] As shown in FIG. 4, the seat 14 can further include a plurality of first elastic members 144 and struts 146. As shown in FIG. 3, the engaging member 142 surrounds the strut 146. As shown in FIG. 4, the opposite ends of each of the first elastic members 144 respectively abut against one of the corresponding engaging member 142 and strut 146. When the unlock button 140 is pressed to move the engaging member 142 in the direction of arrow A2, each of the engaging members 142 compresses the first elastic member 144. When the unlock button 140 is released, the elastic force generated by the first elastic member 144 pushes the engaging member 142 so that the engaging member 142 returns in the direction opposite to arrow A2. At the same time, the engaging member 142 presses the unlock button 140 so that the unlock button 140 returns in the direction opposite to arrow A1.

[0023] As shown in FIG. 4, the unlocking button 140 may have a first inclined surface 1400, and each of the engaging members 142 may have a second inclined surface 1420. The first inclined surface 1400 abuts against the second inclined surface 1420 of each of the engaging members 142. Therefore, when the unlocking button 140 is pressed, the first inclined surface 1400 of the unlocking button 140 presses the second inclined surface 1420 of each engaging member 142, and drives each engaging member 142 to move in the direction of arrow A2 to disengage from the engaging structure 120 of the seat fixing base 12. When the unlocking button 140 is released, the second inclined surface 1420 of each engaging member 142 presses the first inclined surface 1400 of the unlocking button 140, and the unlocking button 140 returns in the direction of arrow A1.

[0024] As shown in FIGS. 2 to 4, a guide groove 1402 may be provided inside the unlocking button 140, and a guide portion 1460 may be provided at the top of the support column 146. The guide portion 1460 is inserted into the guide groove 1402 so that the unlocking button 140 can continue to move linearly with respect to the support column 146.

[0025] As shown in FIGS. 2 to 4, a protrusion 122 may be provided on the seat fixing base 12, and a groove 1462 may be provided outside the support column 146 of the seat 14. The user can align the groove 1462 of the seat 14 with the protrusion 122 of the seat fixing base 12 and place the seat 14 on the seat fixing base 12. When the seat 14 is placed on the seat fixing base 12, the protrusion 122 is inserted into the groove 1462. Therefore, the user can align the seat 14 with the seat fixing base 12 by the cooperation of the protrusion 122 and the groove 1462, and facilitate the installation of the seat 14.

[0026] Referring to FIG. 5, FIG. 5 is a perspective view showing the sheet 14 according to another embodiment of the present invention. As shown in FIG. 5, the sheet 14 can further include a webbing 148, and the webbing 148 is disposed on the upper surface of the sheet 14. To remove the sheet 14, the user can press the unlock button 140 of the sheet 14 with the thumb and pull the webbing 148 upward with the other fingers, and the sheet 14 can be removed from the sheet fixing base 12. Therefore, the user can remove the sheet 14 with one hand. The operation is simple and the structure is simple.

[0027] Referring to FIGS. 6 to 9, FIG. 6 is a perspective view explaining the assembly of the sheet 14 and the sheet fixing base 12 from another view, FIG. 7 is a perspective view explaining the sheet fixing base 12, FIG. 8 is a cross-sectional view explaining the assembly of the sheet 14 and the sheet fixing base 12, and FIG. 9 is a perspective view explaining the state where the sheet 14 is directed toward the back of the baby stroller 1.

[0028] As shown in FIGS. 6 to 8, the seat fixing base 12 can have two positioning recesses 124a, 124b, and the seat 14 can further include a positioning member 150 and a second elastic member 152. The positioning member 150 is disposed on the bottom surface of the base 14. The opposing ends of the second elastic member 152 abut against the positioning member 150 and the seat 14. When the positioning member 150 engages with one of the two positioning recesses 124a, 124b, the seat 14 faces forward in the stroller 1 (as shown in FIG. 1). When the positioning member 150 engages with the other positioning recess 124a of the two positioning recesses 124a, 124b, the seat 14 faces in the rearward direction of the stroller 1 (as shown in FIG. 9). In other words, the positioning member 150 is configured to cooperate with the two positioning recesses 124a, 124b to direct the seat 14 forward in the stroller 1 or to direct the seat 14 rearward in the stroller 1. In the present embodiment, when the positioning member 150 engages with the positioning recess 124a, the seat 14 faces forward in the stroller 1. When the positioning member 150 engages with the positioning recess 124b, the seat 14 faces in the rearward direction of the stroller 1. It should be noted that the present invention can adjust the positions of the two positioning recesses 124a, 124b to direct the seat 14 in other directions of the stroller 1, for example, to direct the seat 14 to the left in the stroller 1 or to direct the seat 14 to the right in the stroller 1. Needless to say, in addition to the two positioning recesses 124a, 124b, the present invention can further add other positioning recesses to the seat fixing base 12 so that the seat 14 can face more different directions of the stroller 1.

[0029] As shown in FIG. 8, the positioning member 150 engages with the positioning recess 124a, preventing the seat 14 from rotating relative to the seat fixing base 12. The user can push the positioning member 150 in the direction of arrow A3 so that the positioning member 150 disengages from the positioning recess 124a. At this time, the user can rotate the seat 14 to adjust its orientation. When the positioning member 150 is pressed to move in the direction of arrow A3, the positioning member 150 compresses the second elastic member 152. When the positioning member 150 is released and aligned with the positioning recess 124a or 124b, the elastic force generated by the second elastic member 152 pushes the positioning member 150, causing it to return in the opposite direction of arrow A3 and engage with the positioning recess 124a or 124b.

[0030] As described above, the frame of the present invention includes a seat fixing base having an engagement structure. When the engagement member of the seat engages with the engagement structure of the seat fixing base, the seat is constrained by the seat fixing base. To remove the seat, the user can press the unlocking button with one hand. When the unlocking button is pressed, the unlocking button drives the engagement member to disengage from the engagement structure, allowing the seat to be removed from the seat fixing base. Further, in the present invention, the webbing can also be disposed on the upper surface of the seat. To remove the seat, press the seat unlocking button with the thumb and pull the webbing upward with the other fingers to remove the seat from the seat fixing base. Therefore, the user can remove the seat with one hand. The operation is simple and the structure is straightforward.
