Description

[Technical Field]

[0001] The present invention relates to a handle switching mechanism and a child stroller. [Background technology]

[0002] Commercially available child strollers usually have a handle direction switching function that allows the caregiver to pivot the handle between a backward direction, in which the handle and rear legs are on the same side, and a forward direction, in which the handle and front legs are on the same side. When the caregiver switches the handle to the backward direction and pushes the child stroller forward, both the caregiver and the child sitting in the child stroller face forward. Therefore, the child has a wider field of view. When the caregiver switches the handle to the backward direction and pushes the child stroller backward, the caregiver and the child sitting in the child stroller face each other. Therefore, the caregiver can easily communicate with the child.

[0003] However, during the handle switching operation, parts located on the handle scratch the lateral handrails on both sides, not only scratching the lateral handrails but also generating scratching noises that are harmful to the child. Therefore, conventional child strollers have a poor user experience. For example, see FIG. 1. FIG. 1 is a partial view of a handle switching mechanism in the prior art. As shown in FIG. 1, the handle switching mechanism includes a sliding sleeve 131' attached to the handle. Because the sliding sleeve 131' is formed by molding, a step structure, as indicated by the dashed line M, is formed on the back surface 1311' of the sliding sleeve 131' due to the back mold insert, which leads to scratches on the lateral handrails.

Accordingly, the drawings and descriptions are to be regarded as illustrative in nature and not restrictive. In the following detailed description of the preferred embodiment, reference is made to the accompanying drawings, which form a part of this specification and which show, by way of illustration, specific embodiments in which the invention may be practiced. Also, the term "connected" is intended to mean either an indirect or direct mechanical connection. Thus, if a first device is connected to a second device, the connection can be via a direct mechanical connection or via an indirect mechanical connection via other devices and connections.

[0030] Please refer to Figures 2 and 3. Figures 2 and 3 are schematic diagrams of a child stroller 100 from different perspectives according to a first embodiment of the present invention. As shown in Figures 2 and 3, the child stroller 100 includes a stroller frame 110, a stroller handle 120, and two handle switching mechanisms 130. The stroller handle 120 is pivotally connected to the stroller frame 110. Each of the handle switching mechanisms 130 is disposed between the stroller handle 120 and the stroller frame 110 to achieve a pivotal switching operation of the stroller handle 120 and to lock the stroller handle 120 to inhibit the pivotal switching operation of the stroller handle 120. The stroller frame 110 includes two side handrails 111, front legs 112, rear legs 113, and two support frames 114. The two side handrails 111 are symmetrically opposite each other and disposed on the left and right sides of the stroller frame 110, respectively. The two support frames 114 are symmetrically opposite each other and disposed on the left and right sides of the stroller frame 110, respectively. Each of the side handrails 111 is connected to a front leg 112 and a rear leg 113, and each of the support frames 114 is connected to the corresponding side handrail 111 and rear leg 113. Preferably, each of the side handrails 111, the front leg 112, the rear leg 113, and the support frame 114 is configured to be pivotable so that the stroller frame 110 can be switched between an unfolded state and a folded state. Specifically, the front end of each side handrail 111 is connected to the front leg 112 and the rear leg 113, and the upper and lower ends of each support frame 114 are connected to the rear end of the corresponding side handrail 111 and the rear leg 113, respectively.

[0031] More specifically, both ends of the stroller handle 120 are pivotally connected to two support frames 114 disposed on the left and right sides of the stroller frame 110, respectively. When the stroller handle 120 is disposed in a rearward direction, the stroller handle 120 and the rear legs 113 are disposed on the same side. That is, both the stroller handle 120 and the rear legs 113 are disposed on the back side of the stroller frame 110. Each of the handle switching mechanisms 130 can be configured to engage or disengage with the corresponding support frame 114 to prevent or enable departure movement of the stroller handle 120 from the rearward direction. When the stroller handle 120 is disposed in a forward direction, the stroller handle 120 and the front legs 112 are disposed on the same side. That is, both the stroller handle 120 and the front legs 112 are disposed on the front side of the stroller frame 110. Each of the handle switching mechanisms 130 can be configured to engage or disengage with the corresponding front legs 112 to prevent or enable departure movement of the stroller handle 120 from the forward direction. Furthermore, during pivotal switching of the stroller handle 120 between forward and rearward facing, each of the handle switching mechanisms 130 may be configured to prevent scratching damage to the corresponding side rail 111 or other structure and to prevent scratching noises.

[0032] 2 and 3, the stroller frame 110 further includes two first engagement parts 140 and two second engagement parts 141, and the first engagement parts 140 and the second engagement parts 141 may have similar structures. The two first engagement parts 140 are arranged on the front legs 112 and are arranged to engage with or disengage from the two handle switching mechanisms 130, respectively, when the stroller handle 120 is positioned forward-facing, to lock or unlock the stroller handle 120 in the forward-facing position. The two second engagement parts 141 are arranged on the two support frames 114, respectively, and are arranged to engage with or disengage from the two handle switching mechanisms 130, respectively, when the stroller handle 120 is positioned rearward-facing, to lock or unlock the stroller handle 120 in the rearward-facing position.

[0033] The stroller frame 110 has a structure and operation principle similar to that of a conventional stroller frame, so a detailed description of the stroller frame 110 is omitted herein for simplicity. Furthermore, the two handle switching mechanisms 130 disposed on the left and right sides of the stroller frame 110, respectively, are symmetrical to each other and have the same structure, so a diagram of the handle switching mechanism 130 on one side is provided as follows:

[0034] Please refer to FIG. 4. FIG. 4 is an exploded view of a handle switching mechanism 130 according to a first embodiment of the present invention. As shown in FIG. 4, each of the handle switching mechanisms 130 includes a sliding sleeve 131, an engagement block 1312, and a sliding component 131a. The sliding sleeve 131 is slidably connected to the stroller handle 120. The engagement block 1312 protrudes from the sliding sleeve 131 and engages with the stroller frame 110. The sliding component 131a is disposed on a side of the engagement block 1312 adjacent to the stroller frame 110. The sliding component 131a is made of an elastic material and has a smooth surface. The sliding sleeve 131 is slidably switchable between a locked position and an unlocked position along the stroller handle 120. When the sliding sleeve 131 slides to the locked position, the engagement block 1312 and the stroller handle 120 engage with each other to prevent the stroller handle 120 from pivoting. When the sliding sleeve 131 slides to the release position, the engagement block 1312 and the stroller handle 120 disengage from each other to allow pivoting of the stroller handle 120. During the pivoting movement of the stroller handle 120, the sliding component 131a can contact the side rail 111 or other structures of the stroller frame 110 to prevent scratching damage to the side rail 111 or other structures and to prevent scratching noises.

[0035] Specifically, the sliding sleeve 131 includes a sleeve body 1311 slidably connected to the stroller handle 120. An engagement block 1312 protrudes from the sleeve body 1311. An engagement notch 1313 is formed on the engagement block 1312. The pushing direction of the engagement notch 1313 is substantially parallel to the longitudinal direction of the sleeve body 1311, i.e., the sliding direction of the sleeve body 1311. The sliding component 131a is disposed on the side of the engagement block 1312 away from the sleeve body 1311, i.e., the side of the engagement block 1312 adjacent to the stroller frame 110. The engagement notch 1313 is configured to engage or disengage with a first engagement part 140 disposed on the front leg 112 or a second engagement part 141 disposed on the support frame 114 to achieve a locking or unlocking operation of the stroller handle 120.

[0036] More specifically, in this embodiment, the sliding component 131a is integrally formed adjacent to the stroller frame 110 so that the side of the engagement block 1312 is away from the sleeve body 1311. The sliding component 131a may have a flat surface structure or an arc surface structure, and an arc-shaped chamfered edge or an arc-shaped beveled edge is formed adjacent to the connection between the periphery of the sliding component 131a and the periphery of the engagement block 1312.

[0037] Preferably, in this embodiment, the sliding sleeve 131, the engagement block 1312, and the sliding component 131a are integrally formed with each other to form a unitary structure and are made of the same elastic material, which may be a thermoplastic elastomer (TPE) or a rubber material.

[0038] However, the materials and manufacturing of the sliding sleeve, engagement block, and sliding component of the present invention are not limited to this embodiment. For example, in another embodiment, the sliding component can be made of an elastic material, and the sliding component and sliding sleeve can be made of any other material. Furthermore, the sliding sleeve, engagement block, and sliding component can be integrally formed with each other, for example, by overmolding, to form a unitary structure.

[0039] Furthermore, the structure of the sliding component of the present invention is not limited to this embodiment. For example, in other embodiments, the sliding component may be a protruding column, a protruding block, a protruding rib, or any other structure.

[0040] 2 to 4, the handle switching mechanism 130 includes a recovering component 134 disposed between the stroller handle 120 and the sliding sleeve 131, and a fixing component 135 attached to the stroller handle 120. The recovering component 134 is housed inside the stroller handle 120. Two ends of the recovering component 134 are connected to the sliding sleeve 131 and the fixing component 135, respectively. When the sliding sleeve 131 is forced to slide toward the release position, the recovering component 134 is elastically deformed by the sliding sleeve 131. When the sliding sleeve 131 is released, the recovering component 134 elastically recovers and drives the sliding sleeve 131 to slide to the lock position. That is, the sliding sleeve 131 is biased by the recovering component 134 to move toward the lock position.

[0041] More specifically, the handle switching mechanism 130 further includes a blocking component 136 and a pivoting component 137. The blocking component 136 is fixed to the stroller handle 120 and disposed below the sliding sleeve 131. The blocking portion 1361 protrudes from the blocking component 136 and is disposed at a position corresponding to the engagement notch 1313. When the engagement notch 1313 engages with the first engagement part 140 or the second engagement part 141, the blocking portion 1361 cooperates with the engagement notch 1313 to restrain the first engagement part 140 or the second engagement part 141, thereby ensuring the locking of the stroller handle 120. Furthermore, the blocking component 136 can be configured to limit the sliding movement distance of the sliding sleeve 131. Additionally, a pivot component 137 is located at the bottom of the stroller handle 120 and is pivotally connected to the support frame 114 to allow the stroller handle 120 to pivot relative to the support frame 114 .

[0042] As shown in FIGS. 2 to 4, the operating principle of the handle switching mechanism 130 is as follows. As shown in FIGS. 2 and 3, the stroller handle 120 is configured to be pivotable relative to the support frame 114 of the stroller frame 110 around a pivot axis P, which is arranged along the left-right direction of the stroller frame 110. When the stroller handle 120 is arranged in the position shown in FIG. 2, that is, when the stroller handle 120 and the rear leg 113 are adjacent to each other and both are located at the rear side of the stroller frame 110, the stroller handle 120 is arranged in the rearward direction. When it is desired to pivotally switch the stroller handle 120 from the rearward direction to the forward direction, the sliding sleeve 131 can be operated and slid upward along the first direction F1 to release the engagement notch 1313 from the second engagement part 141 arranged on the support frame 114. During the aforementioned process, the recovery component 134 can be elastically deformed by the sliding sleeve 131. After the sliding sleeve 131 is placed in the release position, the stroller handle 120 can be pivoted forward along the second direction F2 about the pivot axis P. While the stroller handle 120 pivots forward along the second direction F2 about the pivot axis P, the sliding sleeve 131 is placed at a position corresponding to the side handrail 111. Therefore, the sliding component 131a, which is made of an elastic material and has a smooth surface, can slide along the side handrail 111 to prevent scratching damage to the side handrail 111 and prevent scratching noises. When the stroller handle 120 pivots forward, the engagement notch 1313 is aligned with the first engagement part 140 placed on the front leg 112. At this point, the sliding sleeve 131 can be released and the recovery component 134 can drive the sliding sleeve 131 back to the locked position, engaging the first engagement part 140 with the engagement notch 1313 to lock the stroller handle 120.

[0043] Furthermore, when it is desired to pivotally switch the stroller handle 120 from the forward direction to the rearward direction, the sliding sleeve 131 can be operated to slide to the release position, and then the stroller handle 120 can be pivoted along the direction opposite to the second direction F2. Thereafter, when the stroller handle 120 reaches the pivotally rearward direction, the sliding sleeve 131 can be released to engage the engagement notch 1313 with the second engagement part 141 to lock the stroller handle 120.

[0044] Please refer to Figures 5 and 6. Figure 5 is a partial view of a child stroller 100 according to a second embodiment of the present invention. Figure 6 is a partial view of the child stroller 100 when the protective plate 132 is removed according to the second embodiment of the present invention. As shown in Figures 5 and 6, in this embodiment, the sliding component 131a is not integrally formed with the engagement block 1312. Specifically, the handle switching mechanism 130 further includes a protective plate 132. The protective plate 132 is formed independently and is made of an elastic material. An arc-shaped surface structure having a flat surface structure or a smooth surface is formed on the side of the protective plate 132 away from the engagement block 1312 to form the sliding component 131a. An arc-shaped chamfered edge or an arc-shaped beveled edge is formed around the periphery of the protective plate 132. The shape of the protective plate 132 matches the shape of the side of the engagement block 1312 away from the sleeve body 1311 and adjacent to the stroller frame 110, and the protective plate 132 is installed on the side of the engagement block 1312 away from the sleeve body 1311 and adjacent to the stroller frame 110.

[0045] However, the present invention is not limited to this embodiment. For example, in another embodiment, the at least one protrusion, at least one protruding block, at least one protruding rib, or any other structure may be made of an elastic material, have a smooth surface, and be formed on the side of the engagement block away from the sleeve body and adjacent to the stroller frame to form a sliding component.

[0046] As shown in FIG. 6 , the sleeve body 1311 and the engagement block 1312 of the sliding sleeve 131 may be integrally formed with each other or formed by other methods. The engagement block 1312 has a hollow structure. At least one connecting column 1314 protrudes from the inside of the engagement block 1312. At least one protective plate connecting hole 1321 is formed on the protective plate 132 and disposed at a position corresponding to the at least one connecting column 1314. The protective plate connecting hole 1321 and the connecting column 1314 may be configured to cooperate with connecting components such as screw members, so that the protective plate 132 can be connected to the engagement block 1312 through cooperation of the connecting component, the protective plate connecting hole 1321, and the connecting column 1314 to achieve assembly of the protective plate 132.

[0047] However, the present invention is not limited to this embodiment. For example, in another embodiment, the engagement block may be a solid structure, and the protection plate may be assembled with the engagement block in an engaging or adhesive manner. Alternatively, in another embodiment, the connecting post may be replaced with a screw nut structure or a screw hole structure.

[0048] In addition, in this embodiment, the protective plate 132 can be made of a resilient material such as a thermoplastic elastomer (TPE) or a soft plastic material, and the protective plate 132 and the sliding component 131 a can be integrally formed to form a one-piece structure. However, the present invention is not limited to this embodiment.

[0049] Other structures of the second embodiment are the same as those of the first embodiment, with similar variations, and for the sake of simplicity, detailed descriptions are omitted here.

[0050] Please refer to Figures 7 to 9. Figures 7 and 8 are exploded views of a handle switching mechanism 130 from different perspectives according to a third embodiment of the present invention. Figure 9 is a partial view of a child stroller 100 when an outer cover 133 is removed according to the third embodiment of the present invention. As shown in Figures 7 to 8, in this embodiment, the handle switching mechanism 130 includes a protective plate 132 and an outer cover 133. The protective plate 132 is connected to an engagement block 1312 by the outer cover 133.

[0051] Specifically, in this embodiment, the protective plate 132 is made of an elastic material, and a smooth, flat or arcuate surface structure is formed on the side of the protective plate 132 away from the engagement block 1312 to form the sliding component 131a. However, the present invention is not limited to this embodiment. For example, in another embodiment, the protective plate may be made of an elastic material, have a smooth surface, and have a protrusion, protruding block, protruding rib, or any other structure formed on the side of the protective plate away from the engagement block to form the sliding component. Furthermore, the shape of the outer cover 133 matches the shape of the side of the engagement block 1312 away from the sleeve body 1311 and adjacent to the stroller frame 110 to facilitate connection between the outer cover 133 and the engagement block 1312.

[0052] More specifically, the protective plate 132 and the outer cover 133 may be two separate structures formed independently from different materials and secured together after formation, or they may be a single, integral structure formed integrally from the same or different materials. In this embodiment, the protective plate 132 may be made of an elastic material such as a thermoplastic elastomer (TPE) or a soft plastic material. The outer cover 133 and the protective plate 132 may be made of the same or different materials. The outer cover 133 and the protective plate 132 may be integrally formed with each other, for example, by overmolding, to form a single structure. Furthermore, at least one connecting post 1314 protrudes from the inside of the engagement block 1312. At least one outer cover connecting hole 1331 is formed on the outer cover 133 and positioned corresponding to the at least one connecting post 1314. At least one protective plate connecting hole 1321 is formed on the protective plate 132 and positioned corresponding to the at least one outer cover connecting hole 1331. The outer cover connection holes 1331, the protective plate connection holes 1321 and the connection columns 1314 are configured to cooperate with connecting parts such as screw members, so that the outer cover 133 and the protective plate 132 can be connected to the engagement block 1312 through cooperation of the connecting parts, the outer cover connection holes 1331, the protective plate connection holes 1321 and the connection columns 1314.

[0053] Other structures of the third embodiment are the same as those of the second embodiment, with similar variations, and for the sake of simplicity, detailed descriptions are omitted here.

[0054] Please refer to Figures 10 and 11, which are diagrams of a handle switching mechanism 130 from different perspectives according to a fourth embodiment of the present invention. As shown in Figures 10 and 11, in this embodiment, the sliding component 131a may be a protruding post made of an elastic material, rather than a flat or arc-shaped surface structure.

[0055] 10 and 11, a plurality of protruding columns made of an elastic material are formed on the side of the engagement block 1312 that is remote from the sleeve body 1311. In this embodiment, there may be two protruding columns symmetrically arranged on the side of the engagement block 1312 that is remote from the sleeve body 1311, each of which is arranged on two sides of the engagement notch 1313. The surface of each protruding column may be polished to be smooth so as to reduce friction between each protruding column and the side handrail 111 during pivoting operation of the stroller handle 120.

[0056] More specifically, in this embodiment, the protruding post and the sliding sleeve 131 can be integrally formed with one another and can be made of a resilient material, such as a thermoplastic elastomer or a soft plastic material. However, the present invention is not limited to this embodiment. For example, in another embodiment, the protruding post can be made of a resilient material and the sliding sleeve can be made of a different material. The protruding post and the sliding sleeve can be integrally formed with one another, for example, by overmolding, to form a unitary structure.

[0057] Of course, the structure and number of the sliding component 131a are not limited to this embodiment and depend on actual requirements. For example, in another embodiment, the sliding component may be a protruding block or a protruding rib, and the handle switching mechanism may include at least one sliding component.

[0058] Other structures of the third embodiment are the same as those of the first embodiment, with similar variations, and for the sake of simplicity, detailed descriptions are omitted here.

[0059] In addition, the number of handle switching mechanisms, side handrails, and support frames is not limited to the above-described embodiment. For example, in another embodiment, the child stroller may include only one handle switching mechanism, one side handrail, and one support frame on one side.

[0060] In summary, in this invention, the sliding component is disposed on the side of the engagement block adjacent to the stroller frame, and the sliding component is made of an elastic material and has a smooth surface. The sliding component can contact the side rail or other structures of the stroller frame to prevent scratching damage to the side rail or other structures of the stroller frame and to prevent scratching noises during pivoting of the stroller handle. Therefore, this invention provides an improved user experience. Furthermore, this invention also has the advantages of a simple structure and easy manufacturing.

[0061] Those skilled in the art will readily appreciate that numerous modifications and variations of the apparatus and method may be made while retaining the teachings of the present invention.
