Description

Technical Field

[0001] The present invention relates to the technical field of baby strollers, and in particular to a structure that assists a rider in locking a stroller. Background Art

[0002] Figure 1 The illustrated baby carriage frame includes two front legs 91, two rear legs 92, two side armrests 93 and two seat tubes 94. The upper ends of the front legs 91 and rear legs 92 on the same side are pivotally connected. The front end of the side armrest 93 is pivotally connected to the upper ends of the front legs 91 and rear legs 92. The rear end of the side armrest 93 is connected to a first connecting rod 95, which is in turn connected to a second connecting rod 96. The lower end of the second connecting rod 96 is pivotally connected to the rear legs 92. When the frame is folded, the front legs 91 and rear legs 92 are relatively folded together, and the first connecting rod 95 and the second connecting rod 96 can realize the automatic folding of the side armrests 93. The two seat tubes 94 are used to set a seat for carrying infants. The front end of the seat tube 94 is pivotally connected to the front legs 91, and the rear end is pivotally connected to the first connecting rod 95. For the first connecting rod 95, the seat tube 94 connected thereto is located on the inner side thereof, while the second connecting rod 96 connected thereto is located on the outer side thereof.

[0003] The frame also includes a handle 97, and the parent can push the baby carriage by the handle 97. The handle 97 is installed in the frame in an adjustable manner. Specifically, the handle 97 includes two side rods 971, and the lower ends of the side rods 971 are pivotally connected to the second connecting rod 96 so that the handle 97 can be in a certain position. Figure 1 In the forward use position shown in or swing forward to the rearward use position. When in the forward use position, the baby carriage advances to a side at the front foot 91 place, and when in the rearward use position, the baby carriage advances to a side at the rear foot 92 place.

[0004] Combination Figure 1 , Figure 2 A reversing sleeve 98 is slidably disposed on the side rod 971. An elastic member is disposed in the side rod 971 to provide an elastic force to push the reversing sleeve 98 downward. The reversing sleeve 98 has two push surfaces 981 and a clamping groove 982 located between the two push surfaces 981. A protruding clamping portion 951 is disposed on the outer side of the first connecting rod 95. When the rider 97 swings backward from the rearward use position to the forward use position, the push surface 981 first contacts the clamping portion 951 and drives the reversing sleeve 98 to slide upward. Figure 3As shown. When the push surface 981 is offset from the engaging portion 951, the elastic member pushes the reversing sleeve 98 downward to make the engaging portion 951 engage in the engaging groove 982. A similar engaging portion can also be provided at the front end of the side armrest 93 or the upper end of the front foot 91 to move the rider 97 to the rearward use position. In addition, a limiting sleeve 99 located below the reversing sleeve 98 is fixed to the side rod 971, and a stopper 991 protruding toward the inner side of the frame is provided on the limiting sleeve 99. The limiting sleeve 99 can limit the reversing sleeve 98, and the stopper 991 also abuts against the lower side of the engaging portion 951 to prevent the side rod 971 from shifting upward as a whole.

[0005] like Figure 4 As shown, in an ideal state, the reversing sleeve 98 is perfectly engaged with the engaging portion 951, which can lock the position of the rider 97 and ensure stability and safety during the process of pushing the stroller. However, in actual use, there is a child in the stroller, and the weight of the child will cause the structures on both sides of the frame to move slightly toward the middle. When the first connecting rod 95 shifts toward the middle, the position of the engaging portion 951 does not correspond to the position of the reversing sleeve 98, and the reversing sleeve 98 cannot be engaged with the engaging portion 951. At this time, the position of the rider 97 cannot be locked, which poses a safety hazard.

[0006] Therefore, in order to solve the above problems, it is necessary to provide an auxiliary structure on the frame that is conducive to locking the position of the rider. Summary of the invention

[0042] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0043] Combination Figures 5 to 7 As shown, the present invention provides a rider locking auxiliary structure, which is arranged in a frame 1 of a baby stroller. The frame 1 includes a lower frame 10 and a rider 11 pivotally connected to the lower frame 10. The rider 11 is U-shaped and includes two side rods 111 respectively located on both sides of the lower frame 10. The rider 11 can be in a position relative to the lower frame 10. Figure 5 , or swing forward to a rearward use position relative to the lower frame 10. The lower frame 10 includes a first connecting rod 12, on which a clamping portion 121 protruding toward the outer side of the lower frame 10 is provided, and a reversing sleeve 13 cooperating with the clamping portion 121 is slidably provided on the side rod 111 of the rider 11, and the reversing sleeve 13 is engaged with the clamping portion 121 to lock the position of the rider 11. There are two first connecting rods 12, which are respectively located on both sides of the lower frame 10, and reversing sleeves 13 are also provided on the two side rods 111 of the rider 11. In fact, the two sides of the frame 1 are symmetrical structures, and a detailed description of one side is sufficient. The rider locking auxiliary structure of the present invention includes a convex rib 141 that pushes the first connecting rod 12 outward from the lower frame 10, and the convex rib 141 can minimize the inward displacement of the first connecting rod 12 when the frame 1 is loaded by pushing the first connecting rod 12 outward.

[0044] The lower frame 10 includes two front legs 151, two rear legs 152, two side armrests 16 and two seat tubes 17. For the same side of the lower frame 10, the upper end of the front leg 151 is pivotally connected to the upper end of the rear leg 152, and the lower ends of the front leg 151 and the rear leg 152 are provided with wheels 150. The front end of the side armrest 16 is pivotally connected to the front leg 151 and the rear leg 152, and the rear end of the side armrest 16 is pivotally connected to one end of the first connecting rod 12. The other end of the first connecting rod 12 is connected to a second connecting rod 18, and the other end of the second connecting rod 18 is pivotally connected to the rear leg 152. The lower end of the side rod 111 of the rider 11 is pivotally connected to the second connecting rod 18 so that it can swing relative to the lower frame 10. The front end of the seat tube 17 is pivotally connected to the front leg 151, and the rear end of the seat tube 17 is connected to the first connecting rod 12.

[0045] The first connecting rod 12 is provided with a protruding portion 122 protruding outward, and the above-mentioned engaging portion 121 is fixed at the end of the protruding portion 122 and protrudes upward relative to the protruding portion 122, and the top of the engaging portion 121 is in the shape of an arc surface. The engaging process of the reversing sleeve 13 and the engaging portion 121 is a prior art, and has been described in the background technology, which will not be repeated here. A guide groove 123 is also provided on the protruding portion 122, and the guide groove 123 is located on the side away from the engaging portion 121, and the two sides of the guide groove 123 are open. The first bottom surface 124 of the guide groove 123 is tilted upward, and the second bottom surface 125 connected to the first bottom surface 124 is tilted downward. A guide surface 126 facing upward is also connected to the side wall of the guide groove 123 on the outer side. The guide surface 126 in this embodiment is an arc surface, but it can also be an inclined surface.

[0046] A limiting sleeve 14 is also fixed on the side bar 111 and is located below the reversing sleeve 13. The limiting sleeve 14 has a stopper 140 protruding toward the inner side of the frame 1. Figure 5 In the forward use position shown, the stopper 140 abuts against the oblique lower part of the protrusion 122. The rib 141 is disposed at the upper end of the stopper 140 and protrudes relative to the stopper 140. The rib 141 is a rectangular structure, but may also be a columnar structure.

[0047] When the baby carriage is loaded, the structures on both sides of the frame 1 shift toward the middle. At this time, the position of the engaging portion 121 on the first connecting rod 12 is slightly offset from the reversing sleeve 13, and the two cannot be fully engaged. The position of the guide groove 123 is also closer to the inside than the position of the convex rib 141. In order to lock the position of the rider 11 well, the rider 11 can be pressed down with force, and the side rod 111 drives the convex rib 141 downward to contact the guide surface 126. Under the guidance of the guide surface 126, the convex rib 141 will slide into the guide groove 123. At the same time, the force of the convex rib 141 on the side wall of the guide groove 123 will also push the first connecting rod 12 to move outward, thereby correcting the position deviation of the engaging portion 121 and the reversing sleeve 13, which is conducive to the reversing sleeve 13 being engaged in place, so that the position of the rider 11 is stable and the safety is improved. The width of the guide groove 123 is slightly larger than the convex rib 141 . When the convex rib 141 is located in the guide groove 123 , the convex rib 141 limits the first connecting rod 12 , and the first connecting rod 12 is unlikely to deviate in the width direction of the frame 1 .

[0048] In other embodiments, the guide groove 123 may also be disposed at other positions on the first connecting rod 12 , such as the lower end, but disposing the guide groove 123 at a position close to the engaging portion 121 is a more effective option.

[0049] Preferably, a baffle 128 is connected between the first connecting rod 12 and the protruding portion 122 . When the rider 11 swings from the rearward use position to the forward use position, the baffle 128 cooperates with the stopper 140 to limit the rider 11 .

[0050] like Figures 8 to 10 As shown, in the second embodiment of the present invention, the rib 21 is no longer fixed on the side rod 111 of the rider 11, but is arranged in the lower frame 10. The rib 21 arranged in the lower frame 10 can also push the first connecting rod 12 outward.

[0051] Specifically, the vehicle frame 1 in this embodiment further comprises a quick-insertion cover 2 inserted into the lower frame body 10. The quick-insertion cover 2 is located inside the first connecting rod 12 after being inserted, and the rib 21 is protrudingly provided on the outward side of the quick-insertion cover 2. Fig.11 , a fixing flange 22 for fixing the quick-insertion cover 2 is provided at the edge of the other side of the quick-insertion cover 2, and the quick-insertion cover 2 has a notch 23 that divides the fixing flange 22 into two sections and a top portion 24 located on the side away from the notch 23. The quick-insertion cover 2 in this embodiment is a slightly curved structure, and a buckle arm 25 extends from one side thereof. It is known that the frame 1 is a symmetrical structure, and a first connecting rod 12 is provided on both sides of the frame 1. Therefore, the quick-insertion covers 2 and 3 are respectively inserted into the two sides of the frame 1 to push the two first connecting rods 12 respectively. The two quick-insertion covers 2 are also symmetrical to each other, and the other quick-insertion cover 3 is as shown in FIG. Fig.12 The two quick-insertion covers 2 and 3 can be distinguished by letters, words or graphics.

[0052] Replay Figure 8 and Fig. 9 In this embodiment, the quick-connect cover 2 is inserted between the first connecting rod 12 and the seat tube 17 located inside the first connecting rod 12. After insertion, the quick-connect cover 2 is fixed on the seat tube 17 and the convex rib 21 presses against the first connecting rod 12 outward.

[0053] Refer to Fig.13 The end of the seat tube 17 connected to the first connecting rod 12 is provided with a docking portion 171, and a ring portion 172 is provided on the docking portion 171 for the pivot shaft to pass through, and a positioning lip 173 is provided at the edge of the docking portion 171. After the quick-insertion cover 2 is inserted between the first connecting rod 12 and the seat tube 17, the fixing flange 22 on it covers the docking portion 171, and the buckle arm 25 is buckled on the docking portion 171. At the same time, the abutting top 24 of the quick-insertion cover 2 abuts against the inner side of the positioning lip 173, and the ring portion 172 is just accommodated in the notch 23 provided on the quick-insertion cover 2. After the quick-insertion cover 2 is fixed on the docking portion 171, it can rotate with the seat tube 17, so as to always keep abutting against the first connecting rod 12.

[0054] Specifically, Fig.10 As shown, the rib 21 in this embodiment is a long strip structure, and its extension direction is roughly consistent with the width direction of the first connecting rod 12, so that it can completely abut the first connecting rod 12 as much as possible after insertion. Preferably, the middle part of the rib 21 is higher than its two ends, and the height of the middle part is about 3mm.

[0055] Reference Fig.14 When the frame 1 is in the folded state, the joint position between the docking portion 171 of the seat tube 17 and the first connecting rod 12 exposes a gap a, which is easier to operate. In this state, the quick-insert cover 2 can be inserted into the gap a, and then the frame 1 can be unfolded so that the convex rib 21 can maintain the abutment against the first connecting rod 12.

[0056] In other embodiments, when the lower frame 10 is of other structures, the quick-insert cover 2 can also be inserted between the first connecting rod 12 and other positions. The specific structure of the quick-insert cover 2 in this embodiment is designed to be fixed to the docking portion 171 of the seat tube 17. When it is inserted in other positions, the structure of the quick-insert cover 2 does not need to be the same as in this embodiment, and only the ribs 21 need to be provided. In theory, the ribs 21 can be inserted into the lower frame 10 as a separate structure, and the abutment effect can also be achieved, but the separate ribs 21 are difficult to be fixed in the lower frame 10, so it is better to be attached to the quick-insert cover 2.

[0057] Compared with the prior art, since the present invention provides the convex ribs 141, 21 in the frame 1 to push the first connecting rod 12 outward, it can prevent the first connecting rod 12 of the frame 1 from deviating too much inward when the baby carriage is load-bearing, so that the reversing sleeve 13 can be smoothly engaged with the engaging portion 121, which is beneficial to locking the position of the rider 11 and ensuring stability and safety.

[0058] The above disclosure is only a preferred embodiment of the present invention, which is to facilitate the understanding and implementation of the present invention by those skilled in the art. It certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
