Description

Technical Field

[0001] This invention relates to a folding stroller, a folding cradle, a folding seat, a baby carriage, a stroller, and a luggage system. Background Technology

[0002] Strollers are a convenient tool for parents or other caregivers to transport children (whether newborns, toddlers, or young children). However, strollers are often relatively large and bulky. Therefore, folding stroller designs have been developed to allow the stroller to fold, thus taking up less space and generally being easier for the user to handle, such as for storing or transporting folded strollers.

[0003] For example, a folding stroller is known, in which a folding cradle or seat is mounted on a folding wheeled chassis frame. When both the cradle and the wheeled chassis frame are unfolded, a user can safely transport an infant using the stroller. After use, the stroller can be folded, for example, for storage or transport.

[0004] In some designs, the cradle or seat must first be removed from the chassis before folding the cradle / seat and chassis frame separately. However, this is not very convenient for users. First, once folded, the user needs to transport and safely store two separate items: the folded cradle / seat and the folded chassis frame. Second, moving the stroller from its unfolded state to its folded state requires a series of steps: removing the cradle / seat, folding the cradle / seat, and folding the chassis frame. These difficulties are further amplified when the user not only has to fold the stroller but also needs to watch over the baby who has just been taken out of it to ensure the baby's safety.

[0005] In another design, a folding cradle is mounted on a folding chassis, but there is no need to remove the cradle to move it to the stroller's folded state. Instead, the user first folds the cradle while it is still attached to the frame, and then folds the frame to form a single folded cradle / frame unit.

[0006] Therefore, the first problem mentioned above (i.e., the transportation and storage of two separate items) is avoided. However, at least part of the second problem still exists—when moving the stroller from its unfolded state to its folded state, the user still needs to perform two separate operations: folding the cradle and then folding the frame. Summary of the Invention

[0007] According to a first aspect of the present invention, a folding stroller is provided, comprising:

[0008] A foldable chassis that can move between an unfolded and folded state;

[0009] A folding cradle or seat, supported by the foldable chassis, movable between an unfolded and folded state, and having a supporting surface on which a passenger can recline or sit when the folding cradle or seat is in the unfolded state; and

[0010] A first locking mechanism that, when engaged, prevents the folding cradle or seat from moving from its unfolded state to its folded state, and when released, allows the folding cradle or seat to move from its unfolded state to its folded state.

[0011] The first locking mechanism is released when the foldable chassis moves from its unfolded state to its folded state.

[0105] Figure 1 illustrates various embodiments of a folding stroller 1 according to one aspect of the invention. In this embodiment, the folding stroller 1 includes a wheeled chassis 3 and interchangeable seats 5 and cradles 7, allowing the stroller 1 to be positioned in three main configurations: i) a world-facing (seat facing forward / outward) configuration—see [reference] Figure 1A ii) Stroller configuration with the seat facing the parent / caregiver (seat facing rear-facing / inward) – see Figure 1B and iii) strollers with cradle configuration—see Figure 1C Although Cradle 7 can also be configured for both world-facing and parent / caregiver-facing setups, it's conceivable that the parent / caregiver-facing setup will be the one users almost inevitably use.

[0106] In each of these configurations, the stroller 1 can be folded in a simple and convenient manner without removing the seat / bassyduck from the stroller 1, and the folding process is linked to a single folding process via the wheeled chassis 3 and the bassyduck / seat 5, 7, thus increasing user convenience because the user does not need to perform separate operations to a) fold the bassyduck / seat 5, 7 and b) fold the chassis frame. This understandably overcomes the shortcomings of the aforementioned prior art.

[0107] The configuration of this embodiment further increases the convenience for the user, because the user can fold the stroller 1 of this embodiment with one hand, while the user's other hand is free, for example, holding the hand of the baby who was previously the passenger of the stroller 1.

[0108] For completeness, it should be noted that the three configurations shown in the various parts of Figure 1 are not necessarily exhaustive, and the stroller 1 can also be used in other ways. For example, in one embodiment, the car seat can be mounted to the wheeled chassis 3 via a suitable mounting adapter, for example, the mounting adapter mates with an ISOFIX type connector on the car seat to mount it to the wheeled chassis 3.

[0109] Before proceeding with a discussion of world-oriented / parent-oriented seating configurations, we will first refer to... Figure 2 More detailed shown in the middle Figure 1C The stroller 1 of this embodiment is described using the stroller and cradle configuration.

[0110] Reference Figure 2 (For clarity, the side walls of the cradle 5 are omitted in the figure, and the cradle 5 with an optional canopy C is shown.) The wheeled chassis 3 of the stroller 1 supports the cradle 5 and generally includes a foldable chassis 9, a wheeled bottom frame, telescopic handles 11 for moving (e.g., pushing, pulling, and turning) and folding the stroller 1, and a pair of joints 13 on each lateral side of the foldable chassis 9 to enable the foldable chassis 9 to be folded and also to be releasably connected to cooperating folding joints 15 on each side of the cradle 7.

[0111] When the foldable chassis 9 and the cradle 7 are separated, they can be folded independently of each other. However, conveniently, the foldable chassis 9 and the cradle 7 can also be folded together in a single collaborative process, resulting in the entire stroller 1 in a compact folded state without removing the cradle 7 from the foldable chassis 9. Before discussing the components of the stroller 1 in more detail, an overview of the folding process is given below with reference to the various parts of Figure 3.

[0112] In this embodiment, the folding process includes the following steps in sequence:

[0113] 1. The button on the user-activated telescopic handle 11 ( Figure 3ARelease the telescopic handle 11 from its initial locked position and push it downwards to fold the handle 11. Figure 3B This will release the chassis locking mechanism, which previously held the foldable chassis 9 in its unfolded state;

[0114] 2. The user tilts stroller 1 forward, lifting the rear wheels off the ground, causing them to swing forward under gravity, at which point the foldable chassis 9 begins to fold. Figure 3C This folding motion of the foldable chassis 9 releases the cradle (or seat, depending on the situation) locking mechanism that previously held the cradle 7 (or seat 5) in its unfolded state;

[0115] 3. Then the cradle 7 (or seat 5) folds freely under gravity to achieve a compact folding configuration. Figure 3D );and

[0116] 4. Then the telescopic handle 11 folds completely by continuing to move downwards, causing the stroller 1 to assume its fully folded state. Figure 3E In this embodiment, the stroller 1 is stabilized in a folded state by the front end of the telescopic handle 11, which protrudes through an opening on the lower side of the foldable chassis 9 and supports the stroller 1 on the floor surface (or other surface) in a manner that engages with the rear wheels of the wheeled chassis 3.

[0117] Therefore, it should be understood from the above that this embodiment provides a foldable stroller 1, in which the foldable chassis 9 and the cradle 7 (or seat 3) can be folded without removing the cradle 7 (or seat 5) from the foldable chassis 9, and the folding of the foldable chassis 9 and the cradle 7 (or seat 5) is completed in a single integration process. Furthermore, this embodiment further increases user convenience because the entire folding process can be operated by the user with one hand, while the other hand is free, for example, it can be used to hold the hand of the infant who was previously a passenger in the stroller 1.

[0118] The following sections will provide a more detailed explanation of the cradle 7, the wheeled chassis 3, and the folding process.

[0119] Cradle 7 is also an embodiment of the independently folding cradle aspect of the present invention, such as... Figure 4A and 4B As shown in detail, it includes a padded baseboard 17 on which an infant can be placed, with surrounding sidewalls 18 forming a folded frame 19. The folded frame 19 is covered by inner and outer layers of fabrics 21 and 23 (the fabric layers are in...). Figure 4A(Seen in dashed lines). The folding frame 19 itself includes a bottom frame 25, a base plate 17 mounted on the bottom frame 25 (the bottom frame 25 and the base 17 can be integrally formed as a single piece, so that the bottom frame 25 can be considered part of the base plate 17), and the cradle connector 15 passes through a slotted mounting plate 27 (see...). Figure 5B The upper frame 29 is slidably mounted on each lateral side; and a set of hinged first and second connecting arms 31, 33 are located on each lateral side of the cradle 7. The first (upper) end of each pair of connecting arms is pivotally mounted to a corresponding mounting sleeve 35, which is fixed to each lateral side of the upper frame 29 (see [link to upper frame 29]). Figure 5D The second (lower) ends of connecting arms 31 and 33 are mounted to connector 15. Support legs 36 are provided on the underside of the bottom frame 25 to stabilize the cradle 7 on the ground (or other supporting surface) when the cradle 7 is used independently on the foldable chassis 9. The upper frame 29 of the cradle 7 is also provided with sunshade, canopy, and handle interfaces 37, 39, and 41, to which the sunshade, canopy, and handle (not shown) can be detachably attached by the user.

[0120] Figure 5 shows the joint 15 on the first transverse side of the frame 19 in more detail; the joint 15 on the second side of the frame 19 adopts a corresponding structure, which will not be described in detail here.

[0121] like Figure 5A As best seen in the image, connector 15 includes connector body 43 having a mounting portion 45 on its outer surface. In this embodiment, the mounting portion 45 includes a generally triangular recess with a topmost circular apex, which cooperates with a mounting portion on a corresponding connector of the foldable chassis (described below) to mount the cradle 7 onto the foldable chassis. A protrusion (not shown) is provided on the back of connector body 43, which engages with a laterally extending groove 27a in mounting plate 27 to slidably mount connector body 43 relative to cradle frame 19.

[0122] from Figures 5C to 5E As best shown, the second (lower) end of the first connecting arm 31 is pivotally mounted to the connector body 43 at pivot point 47. Similarly, the second connecting arm is pivotally mounted to the connector body at pivot point 49. However, in the cradle 7 deployed state, the cradle locking lever 51 is biased to engage with the second connecting arm 33, preventing the second connecting arm 33 from pivoting relative to the connector body 43.

[0123] More specifically, in this embodiment, the cradle locking lever 51 is provided with two laterally extending protrusions 52a and 52b. The first of these protrusions, 52a (see...) Figure 5CLocated at the first end 51a of the control lever 51, away from the pivotally mounted second end 51b, and biased by a biasing element such as a spring (not shown) to protrude through and thus engage with a hole 33a formed at the second (lower) end of the second connecting arm 33. The second protrusion 52b of these protrusions (see...) Figure 5A The second connecting arm 33 is positioned between the first and second ends of the control lever 51 and extends through it to engage with the hole 43a in the connector body 43. In this case, the second connecting arm 33 is fixed in place relative to the connector body 43, as... Figure 5A and 5B As shown. Since the second connecting arm 33 is fixed in place relative to the connector body 43, the first connecting arm 31 and the connector body 43 also remain fixed in place relative to the rest of the cradle frame 19, meaning that the cradle 7 is firmly held in place. Figure 4A The cradle locking lever 51, the holes in the second connecting arm, and the connector bodies 33a and 43a can therefore be considered together as a cradle locking mechanism, which is used to prevent the cradle 7 from accidentally folding.

[0124] Viewed from the outside, the second laterally extending protrusion 52b of the cradle locking lever 51 defines a cradle unlocking button 53 that coincides with the position of the mounting portion 45. Pressing this button 53 causes the control lever 51 to move along... Figure 5C The arrow shown rotates in the direction of rotation, resisting the bias of its associated biasing element, to move inward toward the connector body 43. Therefore, sufficient pressure on the cradle unlock button 53 disengages the second connecting arm 33 from the cradle locking lever 51, thereby pivoting the first and second connecting arms 31, 33 relative to the connector 15, thus folding the cradle 7 (see...). Figure 5D and 5E ).

[0125] The disengagement of the second connecting arm 33 from the cradle locking lever 51 also releases the connector 15 itself to move relative to the cradle frame 19, which is achieved by sliding it backward along the groove of the mounting plate 27a (see...). Figure 5D and 5EWithout this relative movement of the connector 15, the pivotal connection of the first and second connecting arms 31, 33 relative to the upper frame 29 and the bottom frame 25 would require the upper frame 29 to move longitudinally (forward) along the bottom frame 25 during folding of the cradle 7. This would result in an undesirable expansion of the footprint of the folded cradle 7, and could also cause the upper frame 29 of the folded cradle 7 to protrude forward to contact the floor before the stroller 1 is fully folded, thus interfering with the overall proper folding of the stroller 1. These problems are avoided in this embodiment by effectively absorbing longitudinal (forward) movement by moving the cradle connector 15 in the opposite (rearward) direction, which would otherwise be observed in the arc of the upper frame 29. This allows the cradle 7 to form a longitudinally compact folded form, where the upper frame 29 folds directly downward, resting on top of the bottom frame 25.

[0126] To begin folding the cradle 7, the cradle locking button 53 can be pressed in either of the following ways: a) when the cradle 7 is mounted on the foldable chassis 9, by moving the moving part of the foldable chassis 8 (specifically, the second folding actuator rod described below) to press the locking button 53 – this corresponds to the folding steps in Figure 3; or b) when the cradle 7 is used independently of the foldable chassis 9, the user presses the locking button 53 with their fingers or by using a suitable tool – this corresponds to the folding steps in Figure 6 discussed below.

[0127] Finally, a cradle-to-chassis mounting lock 55 and a corresponding release button 57 are also provided on the connector body 43, such as... Figure 5A As shown. When the cradle 7 is mounted on the foldable chassis 9, the cradle-to-chassis mounting lock 55 automatically engages with the corresponding part of the foldable chassis connector 13 to lock the cradle 7 in place and prevent its accidental release. When it is necessary to remove the cradle 7 from the foldable chassis 9, the locking engagement is released by pressing the release button 57.

[0128] Now refer to Figure 2 Let's begin a detailed description of wheeled chassis 3.

[0129] The bottom frame of the foldable chassis 9 includes front and rear frame portions 59 and 61, which are hinged to each other at pivot points 63 provided in each chassis joint 13, thereby allowing the entire foldable chassis to be folded. A locking mechanism (described further below) is provided in each joint 13 to prevent the foldable chassis 9 from being accidentally folded.

[0130] The front frame portion 59 has a generally "U"-shaped construction and is formed by two parallel front frame arms 65, which are connected near their front ends (i.e., the distal ends of pivot point 63) by a transverse strut 67. A "self-supporting" 69 used during folding is located at the center of the transverse strut 67. The front ends of each front frame arm 65 serve as mounting points 1 for a corresponding front wheel of a pair of front wheels 71 of the stroller.

[0131] The front wheels 71 are connected to the front frame arm 65 via a rod 73, which itself is pivotally mounted to the front end of the front frame arm 65 via a swivel joint 75 to allow the front wheels 71 to rotate relative to the central longitudinal axis of the stroller 1, thereby providing steering. The rod 73 is configured to offset the hub 71a of each front wheel 71 (and the center of gravity of the wheel / rod combination) from its associated swivel joint 75 in a horizontal plane—this horizontal offset is in… Figure 2B The symbol is marked "X". Therefore, when the stroller 1 is unfolded and its wheels are on the ground, viewed from directly above the stroller 1, the hub 71a of each front wheel 71 is observed at a different position than the swivel joint 75 associated with that wheel 71, because the hub 71a is not positioned directly below its respective swivel joint 75, but rather horizontally offset from it. In this embodiment, the lever 73 is configured such that when the stroller 1 is pushed forward, the hub 71a of each front wheel 71 takes on a horizontally offset position further back (closer to the rear wheel) than the swivel joint 75.

[0132] The rod 73 can be shaped and / or constructed in various ways to achieve this horizontal offset relationship between the center of gravity of the wheel / rod assembly and the swivel joint 75 of the rod 73. The precise manner in which this relationship is achieved is not important, but in this embodiment, this relationship is achieved by providing a plurality of elongated rods 73, each defining a longitudinal rod axis A (see illustration). Figure 2A The axis A forms a non-zero angle θ with the vertical plane Z on the lower side of the ground / rod 73. The specific value of this angle is not particularly important once the above relationship is observed, but it can be, for example, any acute angle less than 90 degrees and non-zero, preferably any acute angle greater than or equal to 10 degrees and less than or equal to 60 degrees, more preferably any acute angle greater than or equal to 20 degrees and less than or equal to 50 degrees, even more preferably any acute angle greater than or equal to 30 degrees and less than or equal to 40 degrees, and most preferably an angle of approximately 35 degrees.

[0133] Returning to the foldable chassis 9, the rear frame portion 61 has a roughly "U"-shaped structure, consisting of two parallel rear frame arms 77, which are connected near their rear ends (i.e., the distal ends of the pivot point 63) by a transverse strut 79. The rear ends of each rear frame arm 77 serve as mounting points for a corresponding rear wheel of one of the pair of rear wheels 81 of the stroller 1.

[0134] Although for the sake of clarity, from Figure 2 The luggage storage area is omitted in the figure, but a luggage storage area is provided below the cradle / seat installation area—this luggage storage area is shown in Figure 21 and discussed in more detail below.

[0135] The telescopic handle 11 includes an outer tube 83 fixed relative to the front frame arm 65, and a pair of inner tubes 85 that can slide within the front frame wall 65 when a button located in the button housing 87 is properly actuated. The button housing 87 is centrally mounted on the handle crossbar 89, which connects the two inner tubes and is used in this embodiment to activate the handle height adjustment and folding of the stroller 1.

[0136] The outer tube 83 is fixed to and passes through the (hollow) front frame arm 65 to allow the front end of the inner tube 85 to pass forward into the front frame arm 65 when the telescopic handle 11 is folded, and then exits through a hole in the front frame wall 65 when the handle is fully folded, where they are used to support the stroller 1 in the folded state (see...). Figure 3E ).

[0137] Figure 7 shows the button housing 87 of the handle 11 in more detail in various parts, wherein the housing 87a of the housing 87 is in Figure 7A The housing 87a is shown in dashed lines, and the rest of the illustration is omitted entirely for clarity. The main handle adjustment button 93 and the secondary handle adjustment button 95, along with a pair of movable sliding elements 97 located on the corresponding inclined inner surface 93a of the main handle adjustment button 93, are housed within the button housing 87.

[0138] Each sliding element 97 is attached via a cable (not shown) to a corresponding locking system in a pair of handle locking systems, one of which is in Figure 8A The handle is generally shown as 101. The handle locking system 101 is located inside the handle 11 and is distributed on the outer / inner tube pairs 83, 85 on one side of the handle 11. Another handle locking system is distributed on another outer / inner tube pair on the other side of the handle 11 and is the same as shown in the various parts of FIG8.

[0139] The handle locking system 101 mainly includes a series of recesses 103 on the inner surface of the (fixed position) outer tube 83, and movable locking height adjusting plates 105, chassis folding plates 107, and chassis folding plate actuators 109, all disposed on the (movable) inner tube 85 of the handle 11. The recesses 103 correspond to multiple predetermined handle heights, and the locking height adjusting plates 105 can selectively engage with the recesses 103 to fix the handle 11 at the desired height. The chassis folding plates 107 and chassis folding plate actuators 109 are used when the stroller 1 is folded.

[0140] When stroller 1 is in its normally unfolded position (see...) Figure 2 In the case of ), the main and auxiliary handle adjustment buttons 93, 95 and the sliding element 97 are biased to their respective biasing elements, such as springs (not shown), to . Figure 7A The initial position is shown in Figure 7B, and the locking height adjustment piece 105 is similarly biased by a locking height adjustment piece biasing element, such as a spring (not shown), to protrude outward to engage with the initial position recess 103a, corresponding to the initial predetermined handle height, as shown in Figure 7B. Figure 8A As shown.

[0141] To adjust the height of the handle 11, the user presses the main handle adjustment button 93 into the button housing 87. As the sliding element 97 slides on the inclined inner surface of the main handle adjustment button 93, this causes the sliding elements 97 to move toward each other (see Figure 7C). This movement of the sliding elements 97 pulls on the cable within the handle 11, which in turn causes the locking height adjustment tab 105 to retract from its engagement with the initial position notch 103a, thus releasing the handle 11 from its initial height position. The user can then move the handle 11 to another predetermined handle height position and release the main handle adjustment button 93, causing the sliding elements 97 to return to their initial positions under the bias of their respective biasing elements (not shown). Due to the bias applied by the locking height adjustment tab biasing elements (not shown), the previous tension on the cable is now released, causing the locking height adjustment tab 105 to protrude and engage with the notch 103 at the current handle height position. The handle 11 is thus secured at its new height position.

[0142] Here, it should be noted that the extent of movement of the main handle adjustment button 93 into the button housing 87 (and thus the amount by which the sliding element 97 pulls the cable) is limited by the protrusion 95a of the secondary handle adjustment button 95, which acts as an end stop by contacting a corresponding protrusion 93b provided on the main adjustment handle 93.

[0143] When folding stroller 1, the user further actuates the secondary handle adjustment button 95 by sliding it laterally to a position where protrusions 93a and 95a are misaligned and thus do not contact each other, as shown in Figures 7D and 7E. This increases the range of motion of the main handle adjustment button 93 into the button housing 87, thereby increasing the amount of cable pulled by the sliding element 97. This further pulling of the cable causes the inclined surface 109a of the chassis folding plate actuator 109 to contact the chassis folding plate 107, forcing it to protrude outward from the inner tube 85 (e.g., Figure 8B and 8C(As shown, discussed below). The protruding chassis folding piece 107 of the handle locking system 101 is then used to unlock the locking mechanism in each chassis frame joint 13 (described in more detail below), thus allowing the foldable chassis 9 to begin folding. It will thus be understood that, by controlling this operation, the auxiliary handle adjustment button 95 serves as a safety mechanism to prevent the stroller 1 from folding accidentally.

[0144] Figures 9 through 13 show the first of two chassis frame joints 13 located on a first side of the foldable chassis 9; the second of the two joints 13 on the other side of the foldable chassis 9 employs the same configuration. Each joint 13 includes a joint housing 111 fixed to the outer tube 83 of the handle 11 (and thus also fixed relative to the front frame portion 59 of the foldable chassis 9), the joint housing 111 containing various joint components; and the aforementioned pivot point 63 serving as a hinged connection between the front frame portion 59 and the rear frame portion 61. A mounting portion 115 is formed on the outer surface of the joint housing 111 for cooperating with the mounting portion 45 of the corresponding cradle joint 15 to support and secure the cradle 7 in place on the foldable chassis 9, wherein in this embodiment, the mounting portion 115 is a generally triangular protrusion with a rounded apex at its uppermost point. A hole 117 is positioned to coincide with the position of the mounting portion 115, particularly when the cradle 7 is supported on the foldable chassis 9, and coincides with the position of the cradle unlock button 53 in the cradle joint 15. As further described below, this enables the cradle unlock button 53 to be pressed automatically when the foldable chassis 9 is folded, thereby allowing the cradle 7 to also be folded.

[0145] Located inside the connector housing 111 is the pivotally mounted chassis unlocking lever 119 (see... Figure 10 and 11), locking beam 121 (see Figure 10 ), and the locking beam track 123 formed on the inner surface of the connector housing 111 (see Figure 10 ), and a secondary folding actuator rod 125, which is located on a cam surface 127 formed on the rear frame portion 61 (see Figure 9B and 9D ).

[0146] As shown in the various parts of Figure 12, the locking beam 121 has a floating first end 121a with a protrusion 121b and a second end 121c pivotally mounted to the upper end of the rear frame portion 61. When the stroller 1 is in its initial unfolded state (i.e., Figure 2When in the state shown, the locking beam 121 adopts the initial position shown in FIG. 12A. Here, the protrusion 121b is located within the unfolded locking recess 123A at the first (upper) end of the locking beam track 123, thereby securing the rear frame portion 61 in place relative to the handle 11 and the front frame portion 59. The locking beam 121 and the locking beam track 123 thus serve as a chassis locking mechanism, holding the foldable chassis 9 in its unfolded state until the user selects to fold the stroller 1.

[0147] Locking beam 121 is also connected to self-support 69 via cable 129 (see...) Figure 13B and 13D The self-support 69 can be in the retracted state (see...). Figure 13A and 13B ) and extended state (see Figure 13C and 13D The self-support 69 moves between the two positions. A biasing element, such as a spring (not shown), is used to bias the self-support 69 into the extended state. However, when the locking beam 121 is in its initial position as shown in FIG. 12A, tension is applied to the cable, which means that the self-support 69 remains in its retracted state when the stroller 1 is unfolded.

[0148] To fold the stroller 1, the user first actuates the auxiliary handle adjustment button 95 in the button housing 87 by sliding the auxiliary handle adjustment button 95 laterally to the position shown in Figure 7D, and then presses down the main handle adjustment button 93 to the extended position shown in Figure 7E. This is as discussed earlier. Figure 3A The initial steps are shown in the diagram. As described above, these actions disengage the locking height adjustment piece 105 from the notch 103 on the outer tube 83, causing the telescopic handle 11 to begin folding (see...). Figure 3B And make the chassis folding piece 107 protrude outward from the outer tube 83.

[0149] The continued folding of the telescopic handle 11 (i.e., the inner tube continues to move downward into the outer tube) causes the protruding chassis folding piece 107 to contact the chassis unlocking lever 119 and apply pressure with a downward component to the chassis unlocking lever 119 (see...). Figure 8C ; Figure 11A The arrow in the diagram indicates the downward force component applied by the protruding chassis folding piece 107. The protruding chassis folding piece has an inclined surface 107a to contact the chassis unlocking lever 119 to allow for smooth actuation of the control lever; the leading edge of the chassis unlocking lever 119 may also have a rounded corner 119a (see [link to diagram]). Figure 8C To facilitate smooth contact between the chassis folding plate 107 and the chassis unlocking lever 119.

[0150] The downward force applied by the chassis folding plate 107 causes the chassis unlocking lever 119 to pivot so that it contacts the first (upper) end of the locking beam 121 (see...). Figure 11BThis contact disengages the locking beam 121 from the locking recess 123a in the deployed state, thereby releasing the rear frame portion 61 from its fixed position relative to the telescopic handle 11 and the front frame portion 59. The user can now simply tilt the stroller 11 forward using the handle (see...). Figure 3C (The arrow in the middle) lifts the rear end of the stroller 1, causing the (unlocked) rear frame portion 61 to swing forward under gravity toward the front frame portion 59, thereby initiating the folding of the foldable chassis 9.

[0151] Because the second (lower) end of the locking beam 121 is pivotally mounted to the rear frame portion 61, it is pulled downward along the locking beam track 123 by the folding movement of the rear frame portion 61 (see Figures 12B and 12C). This downward movement of the locking beam 121 releases tension on the cable 129, allowing the self-support 69 to assume its extended state (see Figures 12B and 12C). Figure 13C and 13D Therefore, when stroller 1 tilts forward, the support 69 extends and contacts the ground, causing the front wheels 71 to lift off the ground, as... Figures 17F to 17I The folding sequence is shown (although seat 5 is shown attached to foldable chassis 9 instead of cradle 7). Friction between the self-supporting bracket 69 and the ground helps to tilt the stroller 1 further forward.

[0152] Additionally, since the self-supporting bracket 69 now replaces the front wheels 71 as the load-bearing element at the front of the stroller 1, the front wheels 71 can rotate freely about their respective swivel mounts 75 (see...). Figures 17F to 17I It should be understood that when all wheels of stroller 1 are on the ground, the initial horizontal offset X of the center of gravity of each front wheel / stem assembly from its associated swivel mount 75 causes a torque about the swivel mount 75 when stroller 1 tilts forward and the front wheels are lifted off the ground. This causes the wheel / stem assembly to swing forward under gravity (see...). Figures 17F to 17H Automatically adopts an aligned stationary position, such that the vertical plane containing each front wheel 71 is parallel to each other and also parallel to the vertical plane containing each rear wheel 81 (see...). Figure 17I This method of automatically aligning the front wheels 71 under gravity advantageously avoids the possibility that the front wheels 71 will remain in the path of the rear wheels 81 when the rear frame portion 51 is folded forward, which would cause the front wheels 71 to interfere with the proper folding of the foldable chassis 9. Furthermore, in this embodiment, a predetermined spacing is ensured between the front wheels 71 in their stationary position, allowing the rear wheels 81 to easily swing to this spacing without contacting the front wheels 71. This enables the foldable chassis 9 to automatically and conveniently adopt a compact folding package (see...). Figure 17J However, the rear wheel 81 can also swing to be positioned on either side of the aligned front wheel pair 71.

[0153] Folding the foldable chassis 9 also unlocks the cradle 7 from its unfolded state. Referring to Figures 9 and 10, and as described above, the secondary folding actuator rod 125 (and more specifically, its first end 125a) rests on a cam surface 127, which is formed on the rear frame portion 61. It will thus be understood that the forward movement of the rear frame portion 61 during forward folding results in the movement of the secondary folding actuator rod 125, governed by the contact between the first end 125a of the secondary folding actuator rod 125 and the cam surface 127. Here, as the foldable chassis 9 folds, the movement of the cam surface 127 relative to the secondary folding actuator rod 125 causes the first end 125a of the secondary folding actuator rod 125 to move further into the connector housing 111 (i.e., away from the mounting portion 115), causing the secondary folding actuator rod 125 to pivot about its pivot point 125b (located at the first end 125A and the second end 125c of the secondary folding actuator rod 125), causing the second end 125c of the secondary folding actuator rod 125 to move forward and finally protrude through the hole formed in the connector housing 111 (see...). Figure 9C and Figure 9D Pressing the cradle unlock button 53 in the cradle connector 16 then releases the cradle 7 from its unfolded state as described above, and uses gravity to pull the upper frame 29 down (now unlocked), thus automatically folding it into its folded state.

[0154] It should be noted that when the rear frame portion 61 (and the rear wheel 81 mounted to the rear frame portion 61) swings forward under gravity, the movement of the secondary folding actuator rod 125 is caused by the folding motion of the rear frame portion 61. Since the rear frame portion 61 and the rear wheel 81 are relatively heavy, a large amount of power is transmitted to the secondary folding actuator rod 125 via the cam surface 127, easily overcoming any friction between the cam surface 127 and the secondary folding actuator rod 125 and providing a firm and reliable actuation of the cradle unlock button 53.

[0155] To complete the folding process, the user applies further downward pressure to the telescopic handle 11, causing the stroller 1 to fold as follows: Figure 3E The fully folded state shown is for example, for convenient transportation or storage of folded packaging. In this embodiment, the stroller 1 is stabilized in the folded state by the front end of the telescopic handle 11, which protrudes through a hole in the underside of the foldable chassis 9 to support the stroller 1 on the ground (or other supporting surface) together with the rear wheels of the stroller 1.

[0156] Therefore, it can be understood that in this embodiment, the user only needs to perform the following actions to fully fold the stroller 1, wherein the stroller 1 includes a foldable chassis 9 and a cradle 7 mounted on the foldable chassis 9, specifically: (i) activating the main and auxiliary buttons 93, 95 on the button housing 87 to release the handle; (ii) pressing down the handle 11 while tilting the stroller 1 forward, causing the foldable chassis 9 and the cradle 7 to fold under gravity; and (iii) continuing to press down the handle 11 until it is fully folded. Similar considerations also apply to the folding of the stroller in "world-facing seat" or "parent-facing seat" configurations, as discussed further below.

[0157] According to this process, it is not necessary to remove the cradle 7 (or seat 5) from the foldable chassis 9 before folding. Furthermore, the foldable chassis 9 and the cradle 7 (or seat 5) are folded in a single related operation, rather than two separate operations. Therefore, the problems related to the prior art discussed in the "Background Art" section above are overcome.

[0158] Furthermore, this embodiment is more convenient because the user can easily and simply perform each of the three operations i) to iii) above (thereby safely folding the stroller 1 in any of the three configurations shown in FIG1) by grasping the handle 11 with one hand and operating the button housing 87, leaving the user's other hand free, for example, by holding the hand of the passenger who was previously in the stroller 1.

[0159] The stroller 1 of this embodiment further includes a releasable locking mechanism associated with the handle 11 and the foldable chassis 9, which advantageously holds the stroller 1 in its folded state until the user wishes to unfold it. This embodiment also includes a handle locking mechanism to prevent the handle 11 from fully folding before a suitable time during the folding process. This latter handle locking structure is more relevant to strollers with a (forward / rear-facing) seat configuration, and therefore strollers with those configurations will be described further below. The releasable locking mechanism for holding the stroller 1 in its folded state is now described below.

[0160] First, refer to Figure 14A Each handle locking mechanism 101 disposed within the handle 11 further includes a handle locking plate 131 mounted on the (slidable) inner tube 85 of the handle 11. The handle locking plate 131 is identical in each case, therefore only one is described here. The handle locking plate 131 is biased to protrude outward by a spring-loaded elastic element 133. When the handle 11 slides downward to its... Figure 3E When fully folded, the handle locking piece 131 engages with the end stop recess 135 located on the (fixed) outer tube side - see Figure 14BAt this point, the handle 11 is locked in its fully folded state, allowing the user to easily lift and move the folded stroller 1 without unfolding it. To release the handle 11 from its locked state, the user simply activates the main handle adjustment button 93 on the button housing 87. This button 93 pulls a cable (not shown) inside the handle 11 and disengages the handle locking plate 131 from the end stop notch 135, resisting the bias provided by the spring-loaded elastic element. The user can then extend the handle 11 again to unfold the stroller 1 (the fully unfolded process is discussed further below).

[0161] Secondly, referring first to Figure 12B, it will be noted that in addition to the unfolded locking notch 123a at its upper end, the locking beam track 123 also includes a pair of folded locking notches 123b, 123c at its lower end. The first notch (123b) of these folded locking notches is slightly higher on the track 123 than the second notch and is used when luggage or items are present in the storage area of ​​the stroller 1 under the cradle / seat to prevent the stroller 1 from being placed in its most compact folded state, corresponding to the lowest folded locking notch 123c. In either case, it should be understood that once the protrusion 121b at the upper end of the locking beam 121 is in place in the folded locking notch associated with the most compact folding form that can be achieved, the rear frame portion 61 of the foldable chassis 9 is locked in place again relative to the rest of the foldable chassis 9, i.e., the stroller 1 remains in its maximum folded state.

[0162] To release this engagement, chassis joint 13 is also provided with a folding chassis release lever 137, as shown in the various parts of Figure 15. During the folding process, first along... Figure 15A and 15B When the handle 11 is moved downwards in the direction indicated by arrow "A" (the former position corresponds to the folding position when luggage is on stroller 1, placing it for further folding, and the latter corresponds to the most compact folding position), the folding chassis release lever 137 is forced (in... Figure 15A In example B, the rotation is counterclockwise, against the bias of the bias element (not shown).

[0163] Then, as Figure 15C As shown, when the handle 11 moves upward again (after releasing the handle locking piece 131, as described above), the folded chassis release lever 137 rotates back to its initial position under the bias of a biasing element (not shown). In doing so, the outer curved surface 137a of the folded chassis release lever 137 contacts the upper end of the locking beam 121, thereby removing it from the folded locking recess 123b / 123c, which it previously occupied when the stroller 1 is folded. The rear frame portion 61 of the foldable chassis 9 is now free to move again and thus the stroller 1 can be unfolded.

[0164] Specifically, in order to unfold stroller 1, the user reverses the folding process as shown in Figure 16, that is:

[0165] 1. User-actuated button housing 87 ( Figure 16A The main and auxiliary handle adjustment buttons 93 and 95 are used to disengage the handle locking piece 131 from the end stop notch 135, and the telescopic handle 11 is extended by pulling it upward. Figure 16B );

[0166] 2. The user tilts the stroller backward 1, causing the front and rear frame sections 59 and 61 to separate and unfold (see...). Figure 16C This action causes the locking beam 121 to return to the locking beam track 123 until it is once again in the locked position as shown in Figure 12(A), so that the foldable chassis 9 is once again held in its unfolded position;

[0167] 3. The user pulls the rear of the upper frame 29 of the cradle 7 (see...). Figure 16D (The arrow in the middle) until the cradle 7 is locked again in its deployed state by the cradle locking lever 51; and

[0168] 4. The user adjusts the telescopic handle 1 to the desired predetermined height, and then releases the main and auxiliary handle adjustment buttons 93 and 95 to complete the unfolding process. Figure 16E ).

[0169] The folding of the cradle 7 in conjunction with the folding of the foldable chassis 9 has been described above; however, it should be understood that the cradle 7 can be used independently of the foldable chassis 9. For example, a user can detach the cradle 7 from the foldable chassis 9 and use the cradle 9 in a nursery or other room, placing the cradle 7 on the ground or other suitable supporting surface, rather than on the foldable chassis 9.

[0170] The folding process of the cradle 7 is now described with reference to 6A to 6C. The cradle is independent of the stroller frame.

[0171] With cradle 7 empty, the user first uses their finger or a suitable pressing tool to press the cradle unlock button 53 on each cradle joint 15 to release the locking engagement between the cradle frame 19 and the joint 13 (see...). Figure 6A The user then presses down and forward on the upper frame 25 (see...). Figure 6B (See arrow in the image) to cause the first and second connecting arms 31, 33 of the cradle frame 19 to begin pivoting. Upper frame 29 (see...) Figure 6C The continuous vertical downward pressure on the arrow in the figure causes the cradle 7 to fold completely, and the cradle joint 15 slides backward to absorb the longitudinal movement of the pivot connecting arm 31, as described above, to allow the upper frame 29 to fold directly downward onto the bottom frame 25 and provide a compact folded coverage area.

[0172] Here, it should be noted that the legs 36 on the underside of the bottom frame provide sufficient ground clearance for the joint 15 and the pivoting connecting arms 31, 33 to move freely throughout the folding process without contacting the floor surface (or other supporting surfaces, such as a tabletop).

[0173] To deploy the cradle 7, the user simply lifts the upper frame 29, causing the connector 15 and the first and second connecting arm pairs 31, 33 to move back to their initial positions until the cradle locking lever 51 of each connector re-engages with its corresponding second connecting arm, wherein this engagement is preferably audible with a "click" to hold the cradle 7 in its deployed state once again.

[0174] It should also be understood that the cradle aspect of the present invention, and therefore its advantage of a compact folding footprint, can also be applied to cradles that are not suitable for mounting on a stroller but are intended for standalone use only. Therefore, embodiments of the standalone cradle aspect of the present invention extend from cradles that can be mounted on a stroller to standalone cradles configured not to be mounted on a stroller frame or similar component.

[0175] A stroller with a cradle configuration has already been described; now a stroller with a world-facing / parent-facing seat configuration will be described, which similarly folds without removing the seat from the chassis frame in a single interconnection process, and in this embodiment can be advantageously folded with one hand by the user.

[0176] Figures 17 and 18 show stroller 1 in its folded state from its "parent-facing seat" and "world-facing seat," respectively. The folding process is similar to that of the "stroller with cradle" configuration, because the folding of the foldable chassis 9 of the wheeled chassis 3 causes the secondary folding actuator 125 of the frame joint 13 to disengage from the locking mechanism within the joint on either side of the seat 5, which in turn allows the seat 5 to fold under gravity as stroller 1 tilts forward. Given the similarity of the folding process, the following discussion focuses on the joints of the seat 5, which are shown in various parts of Figure 19; like the cradle 7, the joints on both sides of the seat 5 are identical to each other, so only one of the joints will be described.

[0177] like Figure 19AAs shown, seat 5 includes a seat cushion or bottom frame 139 (only the portion closest to the connector is shown in the figure), a reclining seat back frame 141 (also only the portion closest to the connector is shown in the figure), and a "bumper" socket 143, all of which are connected by a central seat connector 145. The seat back frame 141 is releasably engaged with connector 145 to rotate about the central seat connector 145 when released to fold seat 5, thus positioning the seat in a fixed upright or reclining position for a child to sit or lean against. Bumper socket 143 is initially connected to seat back frame 141 via a detachable connector (not shown) and therefore rotates with movement of seat back frame 141. The bottom frame 139 rotates freely about connector 145 but is supported by... Figures 19A to 19C As shown, its approximately horizontal position, when the stroller 1 is unfolded, rests on the horizontal upper surface 146a of the bosses 146 formed on each side of the rear frame portion 61—see Figure 11A .

[0178] The seating portion (whether padded, netted, or similar) is mounted on the bottom frame 139 for the stroller passenger to sit on. The seat back frame 141 similarly mounts the seat back (whether padded, netted, or similar) for the stroller passenger to lean against. The bumper insert 143 allows the bumper to be detachably attached to the seat 5. For clarity, the bumper is omitted in this figure, but examples of the bumper 143a are shown in various portions of Figures 17 and 18 as being mounted to different parts of the seat 5.

[0179] It should be understood that the lever 143a provides a safety element by helping to keep the child in the seat 5 (in addition to any seat belts that may be provided (not shown)), provides a handrail for the child to grip during stroller use, and further provides the user with an additional handle, for example, to assist in maneuvering the stroller when loading a folded stroller into the vehicle.

[0180] Turning now to the seat connector 145 itself, externally, the seat connector 145 includes a generally cylindrical connector housing 146, which has a mounting portion 147 on its circular end face surface. In this embodiment, the mounting portion 147 includes a generally triangular recess with a circular apex at its uppermost point, for cooperating with a mounting portion 115 on the corresponding connector 13 of the foldable chassis 9 to mount the seat 5 onto the foldable chassis 9. A hole 149 is located at the center of the circular end face of the connector housing 146. As explained further below, this allows the secondary folding actuation rod 125 of the foldable chassis connector 13 to contact the first end 151a of the seat locking element 151 located within the seat connector 145, thereby releasing the seat 5 for folding. The seat locking element 151 in… Figure 19CAs shown in the figure, and further provided at its second end 151b, a protrusion is provided for engaging with the seat tilt position selector 153 fixedly mounted in the seat joint 145 (see Figure 153). Figure 19B Selective engagement of any one of the multiple holes 153a.

[0181] Each hole 153a of the seat tilt position selector 153 corresponds to a predetermined tilt position of the seat back 141. During normal use of the unfolded stroller 1, the engagement between the protrusion 151b and the seat tilt position selector 153 keeps the seat back 141 in a fixed position relative to the connector 145, at one of the predetermined tilt positions. A handle (not shown) is provided at the top of the seat back frame 141, and the handle is connected via a cable (not shown) to the second end of the seat locking element 151. To adjust the tilt position of the seat back, the user simply pulls the handle, disengaging the protrusion 151b from the hole 153a in the seat tilt position selector 153; the seat back can then be rotated relative to the connector 145 to another predetermined seat back tilt position, where the protrusion 151b will re-engage with the seat tilt position selector 153 at the hole 153b corresponding to the new seat back position.

[0182] As described above, the secondary folding actuator rod 125 of the chassis connector 13 can contact the first end 151a of the seat locking element 151 through the hole 149. This contact also releases the seat back frame 141 to rotate about the seat connector 145 as part of the seat folding process. When the first end 151a of the seat locking element 151 is pressed, the seat locking element 151 moves inward into the connector housing 146, thereby disengaging the protrusion from the seat tilt position selector 153. Therefore, the seat locking element 151 and the seat tilt position selector 153 can be considered together as a seat connector locking mechanism.

[0183] Advantageously, the first end of the hole 149 and the seat locking element 151 is located at the center of the end face of the connector housing 146. This means that the seat locking element 151 can be easily and simply actuated by the secondary folding actuator rod 125 of the chassis connector 13, regardless of whether the seat 5 is "world-facing" or "parent-facing"—in either case, the position where the secondary folding actuator rod 125 of the chassis connector 13 needs to contact the seat connector 145 is the same (i.e., at the center of the seat connector 145). Therefore, the actuation mechanism remains simple, eliminating the need for different actuation processes depending on the seat orientation.

[0184] As described above, the stroller folding process is similar to the cradle configuration process—by properly manipulating buttons 93, 95 on the button housing 87, the user begins to fold the stroller frame handle 11, wherein the chassis folding piece 107 protrudes outward from the inner tube of the handle 11, which in turn actuates each chassis joint 13 (see Figure 11Aand Figure 11B The chassis unlocking lever 119 causes the locking beam 121 to emerge from the unlocking recess 123a in the unfolded state, thereby releasing the rear frame portion 61 from its fixed position relative to the telescopic handle 11 and the front frame portion 59. The user can now simply lift the rear end of the stroller frame using the handle 11, tilt the stroller 1 forward, and cause the (unlocked) rear frame portion 61 to swing forward under gravity toward the front frame portion 59, causing the foldable chassis 9 to begin folding. With the load-bearing element at the front of the stroller 1, the self-support 69 is in the extended state and the front wheel 71 is replaced. Thus, under the gravity as described above, the front wheel 71 automatically comes into its aligned position for easy folding. Furthermore, the folding of the rear frame portion 61 toward the front frame portion 59 again causes the sub-folding actuator rod 125 to move, controlled by the first end of the sub-folding actuator rod 125 and the cam surface 127 on the rear frame portion 61, such that the second end of the sub-folding actuator rod 125 protrudes toward and eventually through the hole 117 formed in the connector housing 111, this time pressing the first end 151a of the seat locking element 151, thereby releasing the seat back frame 141 as the stroller 1 tilts forward by the user, allowing it to rotate freely about the connector under gravity. When the seat back frame 141 is released, it rotates freely clockwise and counterclockwise about the connector 145. Therefore, in the "parent-facing" configuration of Figure 17, the tilted seat back falls back (see... Figures 17C to 17I ) so that it is generally face down in the folded stroller (see Figure 17J In the "world-facing" configuration of Figure 18, the reclining seat back rotates forward, again presenting a generally downward position in the folded stroller.

[0185] As described above, there is initially a releasable connector (not shown) between the bumper insert 143 and the seat back frame 141, meaning that the bumper insert 43 (and thus the bumper mounted in the insert) initially rotates about the seat joint 145 relative to the seat back frame 141. As the seat back frame 141 approaches its final downward position, this releasable connector is released (e.g., via a protrusion, not shown), meaning that the bumper insert 143 can then rotate further about the seat joint 145 relative to the seat back frame 141, taking a position closer to the seat back frame 141 (i.e., reducing its position). Figure 19A The angle α shown in the figure further reduces the size of the folded seat.

[0186] As for the seat base 139, from Figure 18AAs shown in the "world-facing seat" configuration, the folding movement of the rear frame portion 61 means that the upper surface 146a of the boss 146 that initially supports the seat base frame 139 moves downward relative to the horizontal plane (see Figure 12A) (see Figure 12B), allowing the seat base frame to rotate around the joint, ultimately moving approximately vertically downward, as... Figure 18H As shown.

[0187] As seen in the "parent-facing seat" configuration in Figure 17, the rotation of the seat back frame 141 causes the leading edge 141a of the seat back frame adjacent to the connector to impact the corresponding portion 139a of the seat base frame (see Figure 17). Figure 19A The impact causes the seat base frame to rotate about the joint in the same direction of rotation as the seat back frame 141, in order to employ... Figure 17J Its folded state.

[0188] Therefore, it will generally be understood that the folding stroller 1 can also be conveniently folded by the user from either its "parent-facing seat" or "world-facing seat" configuration without removing the seat 5 from the foldable chassis frame 9 and without requiring the user to perform separate folding operations on the foldable chassis frame 9 and the seat 5. Similarly, a further advantage of the stroller 1 in this embodiment is that it can be folded using only one hand, while the user's other hand is used, for example, to hold the hand of the child who was previously a passenger in the stroller 1.

[0189] As described above, this embodiment also includes a handle locking mechanism to ensure that the handle 11 is prevented from fully folding before the appropriate time during the stroller folding process. Specifically, when folded from the "parent-facing seat" configuration, the seat base frame 139 and the bumper, carried by the bumper insert 143, rotate about the seat joint 145 to move from one side of the handle 11 to the other, passing under the crossbar 89 of the handle 11 (see below). Figures 17E to 17I The handle locking mechanism is primarily designed to prevent the handle 11 from interfering with the rotation of the seat back 141 or seat base 139, i.e., to prevent the seat back or base from being trapped on the “wrong” side of the handle 11 before they are in a bent or folded state. However, it should be understood that such a mechanism may also be useful, for example, to prevent interference between the handle and the folding cradle 7, especially when the cradle 7 has high sidewalls.

[0190] Referring to the various parts of Figure 20, the handle locking mechanism is generally shown at 155 and includes a generally "T"-shaped movable handle locking element 157, which is pivotally mounted to the chassis frame joint 13 at a first end 157a and has a blocking protrusion 157b and a contact protrusion 157c at opposite ends of its second end. The contact protrusion 157c rests on a curved surface 159, which is formed on the rear frame portion 61. When the foldable chassis 9 is in its unfolded state, the contact between the contact protrusion 157c and the curved surface 159 causes the blocking protrusion 157b to project upward from the chassis joint 13 (see Figure 20). Figure 20A This prevents the inner tube 85 of the handle 11 from moving further forward to the blocking protrusion 157b, thus limiting the extent to which the handle 11 can be retracted and folded. As the contact protrusion 157c rests on the curved surface 159, subsequent movement of the rear frame portion 61 (when folding the foldable chassis 9) causes the blocking protrusion 157b to gradually move downwards until it no longer protrudes upwards to the chassis joint 13, thereby releasing the handle 11 to full folding. However, at this point, the foldable chassis 9 itself is almost or completely folded, meaning that the seat 5 (or cradle 7) supported on the foldable chassis 9 can also be assumed to be almost or completely folded. Therefore, full folding of the handle 11 (which would otherwise interfere with the folding of the seat 5 or cradle 7) can be prevented before a suitable point in the folding process.

[0191] The luggage aspect of the invention will now be described. As shown in the various parts of FIG21, the wheeled chassis 3 of the above embodiment includes a luggage storage area 161 below the seat / cradle mounting point (the seat and cradle are omitted in FIG21 for clarity of illustration of the luggage storage area). In this embodiment, the luggage storage area 161 includes a generally horizontal support surface 161a on which luggage or other items can be placed, and two lateral sidewalls 161b that help hold luggage / items on the support surface 161a, all of which extend between the front and rear frame portions 59, 61 of the foldable chassis 9 below the seat / cradle mounting point. In this embodiment, the lateral support pillars 79 of the rear frame portion 61 also help hold items on the support surface 161a and thus also form part of the luggage storage area 161. The luggage storage area 161 is foldable to fit the foldable chassis 9. In this embodiment, this is achieved by forming a horizontal support surface 161a and a transverse sidewall 161b of a luggage storage area 161 made of a flexible material (e.g., foldable fabric or mesh), although other examples are also possible, such as the luggage storage area 161 may include a suitably hinged panel so as not to interfere with the folding of the foldable chassis 9.

[0192] Figure 21AThe image also shows a baggage item 163, configured to be placed on a baggage storage area 161 and, in this embodiment, in the form of a bag. The bag 163 has a front and rear panel 165, side panels 167, and one or more openings 169 to provide one or more cavities or compartments for storing items within the bag 163. The bag 163 further preferably includes a handle 171. In the foregoing, the bag 163 of this embodiment can be understood as a "handbag" in the general conventional sense. However, the bag 163 also includes unconventional features.

[0193] First, connecting element 172a ( Figure 21A Only one connecting element 172a is shown; a second connecting element (located at a corresponding position on the other side of the bag 163) is provided on either lateral side of the bag 163 to form a releasable connection with a corresponding connecting element 172b (again, only one is shown), which is located on either lateral side of the rear of the foldable chassis 9. In this embodiment, connecting elements 172a, 172b include cooperating magnetic elements. For example, cooperating connecting elements 172a, 172b may include a pair of magnets that attract each other, or one of a pair of cooperating connecting elements 172a, 172b (e.g., each connecting element 172b on the foldable chassis 9) may be a magnet and the other of a pair of cooperating connecting elements 172a, 172b (each connecting element 172a on the bag 163) may include a portion of a magnetic material, such as a piece of ferromagnetic material, like iron or steel, strongly attracted by a magnet. Although the magnetic connecting element 172a is located on the outside of the bag 163 in this embodiment, it can be covered, for example, hidden under the fabric of the side panel of the bag 163, as long as the magnetic attraction between the connecting elements 172a and 172b is still strong enough to form a reliable and releasable connection between the bag 163 and the foldable chassis 9.

[0194] A magnetic connection between the bag 163 and the collapsible base 9 is preferred because it is more convenient for the user—the releasable connection between the bag 163 and the collapsible base 9 can be easily established by properly positioning the connecting element 172a of the bag 163 close to the connecting element 172b on the base 9. However, the connecting element can also take other forms, such as mating poppers and sockets, patches of hook and loop material (e.g., Velcro (RTM)), or any other suitable releasable connection method.

[0195] Regardless of the type of connecting element used, it should be understood that it is beneficial to releasably attach the bag 163 to the rear of the foldable chassis 9, because this means that... Figure 3E and 17GAs shown, when the stroller 1 is folded, the user can still access the bag 163. When the stroller 1 is folded, the rear frame portion 61 is at the very back, thus keeping the bag 163 accessible at the rear of the folded stroller 1. It should also be understood that when the stroller 1 is in its unfolded state, attaching the bag 163 to the rear frame portion 61 also advantageously facilitates easy access to the bag 163 and its contents, such as... Figures 21B to 21D As shown.

[0196] Secondly, the bag 163 is specifically configured (in size and shape) to fit with the foldable chassis 9 and the luggage compartment 161, and particularly has a suitable width to bridge the gap between the lateral sides of the rear frame portion 61. This is advantageous because when the bag 163 is placed on the luggage compartment 161, it acts as an additional rear retaining wall, helping to keep other items or items on the horizontal support surface 161a. Furthermore, the fitting bag width ensures that when the bag 163 is placed on the luggage compartment 161, the connecting element 172a on the bag 163 is automatically and conveniently positioned near the corresponding connecting element 172b on the chassis 9.

[0197] Third, the side panel 167 of the bag 163 has an additional material 173 at the connection between the side panel 167 and the front panel 165a (see Figure 21C , 21D This allows the bag (and its storage capacity) to be expanded. To keep bag 163 in its... Figure 21A In its normal, unfolded configuration, bag 163 also features detachable attachments, such as snap fasteners, zippers, etc. (not shown), which provide a releasable connection between the unfolded side panel 167 and the front panel 165a. When secured, the releasable attachments hold the front panel 165a in a fixed position relative to the unfolded side panel 167, with the additional material of the side panel 167 remaining folded within the body of bag 163; the user simply releases the attachments to unfold bag 163. When bag 163 is mounted on the foldable chassis 9, unfolding bag 163 not only increases storage capacity but also creates a larger opening, thus facilitating the insertion and removal of items from bag 163.

[0198] Fourth, vertical zipper 175 ( Figure 21C One of the vertical zippers 175 is shown for attaching the side panel 167 to the back panel 165b of the bag. In such a case... Figure 21A During normal use of the bag, the zippers remain fastened, thus securing the side panels 167 and the back panel 165b in a fixed relationship. However, conveniently, the user can unzip these zippers to lower the back panel 165b of the bag to lie flat on the horizontal support surface 161a, so that the luggage storage area 161 effectively extends to and includes the luggage storage area provided by the bag 163. Figure 21DAs shown, this is particularly beneficial when the side panels 167 of the bags 163 are in their extended state, as this maximizes the available luggage storage area.

[0199] Although the folding stroller 1 described in conjunction with the foregoing embodiments describes luggage 163, it should be understood that luggage 163 can also be applied to non-folding strollers with a hanging luggage storage area.

[0200] The features described in the foregoing description, or the following claims, or the accompanying drawings, in their particular form or according to the manner in which they are described to perform the disclosed functions, or the methods or processes for obtaining the disclosed results, may be used alone or in combination of these features, if appropriate, to realize the invention in various forms.

[0201] Therefore, the foregoing embodiments of the invention have been described by way of example only. Those skilled in the art will understand that various modifications can be made without departing from the scope of the invention as defined by the claims. The following are non-exhaustive alternative modifications, which are also embodiments of the invention.

[0202] Exemplary modifications

[0203] In the above-described stroller embodiments, the stroller 1 can be placed in various configurations of FIG. 1 by providing a wheeled chassis 3 with a removable and repositionable seat 5 and a cradle 7. However, it will be understood that, according to other embodiments, the stroller does not need to provide this level of adaptability, especially where a simpler or less expensive device is preferred. For example, the stroller may be provided with only one of the seat or the cradle, and further, the seat or the cradle may or may not be removed from the wheeled chassis.

[0204] In the above embodiments, the chassis locking mechanism is contained within the chassis joint housing 111, and the cradle and seat locking mechanisms are contained within the cradle and seat joints 15 and 145, respectively. However, this is not necessarily the case, and the chassis locking mechanism may be provided wholly or partially by components carried by other parts of the cradle or seat or stroller, including by chassis handles; similarly, the cradle and seat locking mechanisms may be provided wholly or partially by components carried by other parts of the foldable chassis or stroller, including by chassis handles.

[0205] In the above embodiment, moving (folding) the handle 11 releases the foldable chassis 9 to fold, and the folding movement of the chassis 9 releases the seat 5 or cradle 7 to fold. In the modification, moving (folding) the handle instead releases the cradle / seat locking mechanism to allow the cradle / seat to fold under gravity when the stroller tilts forward. The folding of the cradle / seat then releases the chassis locking mechanism, which in turn also allows the chassis frame to fold under gravity; therefore, it should be understood that in this modification, the action of the joint between the cradle / seat and the chassis frame is effectively reversed, such that the folding action of the cradle / seat becomes the cause of releasing the chassis frame locking mechanism.

[0206] More generally, the above embodiments can be modified such that movement of the first of any one of the chassis frame, cradle / seat, or handle from its unfolded / extended state toward its folded / folded state releases the locking mechanism of the second of these components, allowing the second of these components to move toward its folded / folded state. Simultaneously, the movement of the second of these components toward its folded / folded state releases the locking mechanism of the third of these components, thereby enabling the third of these components to move into its folded / folded state. For example, an embodiment of this modification is also an aspect of the invention:

[0207] 1. The user first loosens the chassis frame locking mechanism and folds the chassis frame. The folding motion loosens the handle locking mechanism, causing the handle to collapse / fold. The movement of the handle releases the cradle / seat locking mechanism, causing the cradle / seat to fold.

[0208] 2. The user first releases the chassis frame locking mechanism and folds the chassis frame. The folding motion releases the cradle / seat locking mechanism, and the cradle / seat folding unlocks the handle locking mechanism to allow the handle to collapse / fold.

[0209] 3. The user first releases the cradle / seat locking mechanism and folds the cradle / seat. The folding motion then releases the handle locking mechanism, causing the handle to collapse / fold. This motion then releases the chassis frame locking mechanism, allowing the chassis frame to fold.

[0210] 4. The user first releases the cradle / seat locking mechanism and folds the cradle / seat. The folding motion then releases the chassis frame locking mechanism, and subsequently the folding of the chassis frame releases the handle locking mechanism to allow the handle to collapse / fold.

[0211] In another modification, also an embodiment of one aspect of the invention, the movement of the first of any of the chassis frame, cradle / seat, or handle from its unfolded / extended state toward its folded / collapsed state simultaneously or sequentially releases the locking mechanisms of the second and third of these components, enabling the second and third of these components to also move to their folded / collapsed states. For example, in this modification, the user first folds the handle, a movement that simultaneously or sequentially releases the chassis locking mechanism and the cradle / seat locking mechanism to allow the chassis and cradle / seat to fold under gravity when the stroller is tilted.

[0212] The reference to "baby stroller" should be interpreted as including baby strollers, children's strollers, and folding baby strollers. Furthermore, although embodiments of baby strollers for children or infants have been described above, it should be understood that various aspects of the invention can be applied to wheelchairs for children or adults. Therefore, the reference to "baby stroller" should also be interpreted as including wheelchairs for children or adults.

[0213] In the modified embodiment of the invention regarding luggage, unlike the case where there is a zipper connection between the sidewalls 167 and the back panel 165b, the side panels may have additional material at their junction with the back panel to allow the back panel to move downwards into the luggage storage area, lying flat on a horizontal support surface. It should be understood that this modification also results in the luggage storage area effectively extending to and including the luggage storage area provided by the bag. Furthermore, the additional material attached to the sides of the back panel can advantageously help hold items laterally in the luggage storage area.
