[0005] Stroller that can be converted between a storage configuration and a usage configuration

[0006] Description

[0007] The invention relates to a stroller that can be converted between a storage configuration and a usage configuration, and to a method for converting a stroller.

[0008] Foldable strollers that can be converted from a usage configuration to a storage configuration are known in the prior art. For example, WO 2016 / 135074 A1 describes a stroller with a foldable child seat. The child seat comprises a backrest, a seat element, and several adapter elements by which the child seat can be connected to a stroller, as well as a locking element by which the seat element can be locked relative to the adapter elements. The locking element is designed such that the locking of the seat element relative to the adapter elements can be released by reducing the angle between the backrest and the seat element.

[0009] Solutions known in the state of the art for converting the child seat from a usage configuration to a storage configuration are still perceived as comparatively complex, especially with regard to operation.

[0010] The particular object of the invention is to propose a stroller and a corresponding method, whereby in a comparatively simple manner and MEISSNER BOLTE M / CUU-404-PC 2

[0011] How a transition between a usage configuration and a storage configuration should be possible.

[0012] This problem is solved in particular by the features of claim 1.

[0013] In particular, the problem is solved by a stroller with a chassis, a handlebar and a child carrying device, wherein the stroller is convertible between a storage configuration and a usage configuration, wherein the handlebar has a lower handlebar section and an upper handlebar section which are movably (in particular by hinges) connected to each other, wherein the child carrying device comprises a first area and a second area which are movably (in particular by hinges) connected to each other, wherein the upper handlebar section is movable (in particular pivotable) relative to the lower handlebar section such that the first area moves relative to the second area.

[0014] One aspect of the invention is that a slider with sliding sections movable relative to each other is provided, whereby the first section of a child restraint can be moved relative to a second section of the child restraint by means of a relative movement of the sliding sections. This allows for a simple transition from the operating configuration to the storage configuration (and / or vice versa). In particular, it takes advantage of the fact that a user initially orients themselves using the slider as the central operating element (for pushing the stroller) when picking up a stroller (especially in the operating configuration, but also in the storage configuration).Furthermore, movement of the push bar section can be intuitively assisted by gravity (especially in the operating configuration), which can further simplify operation. For example, when releasing a lock, little or no force is required to initiate movement. Overall, the operation of the stroller is simplified. From a design perspective, this also cleverly utilizes the fact that relative movements, particularly pivoting, of individual sections are necessary anyway to carry out a storage operation (or the reverse process of converting to the operating configuration). MEISSNER BOLTE M / CUU-404-PC 3.

[0015] The underframe can have at least one, or at least or exactly two (particularly interconnected) front wheel stays. The at least one front wheel stay can be rotatably integrated into the underframe about an underframe axle. Furthermore, the underframe can have at least or exactly one, or at least or exactly two rear wheel stays, which are preferably rotatably integrated into the underframe about a (further or the above) underframe axle. At least one wheel, or at least or preferably exactly two wheels, are attached to the (respective) front wheel stay and / or the (respective) rear wheel stay. In a specific embodiment, two front wheel stays and two rear wheel stays are provided, each with exactly one wheel attached. In general, preferably at least one front wheel is provided and at least two rear wheels or corresponding stays are provided. If here (hereinafter or(above) where a respective wheel is mentioned, this can also be formed by a twin wheel, whereby the singular can also be used in such a case.

[0016] The slider may have a right and a left slider strut. The slider struts may be connected to each other by a crossbar (particularly at a distal upper end of the slider struts) or not be connected by such a crossbar (or more generally, not at all, at their upper end). Where reference is made above and below to a lower structure, for example, the lower slider section, and an upper structure, for example, an upper slider section, this refers to the positioning in the operating configuration.

[0017] A "usage configuration" refers to a stroller in which a child can be placed in the child carrier and transported using the stroller. In this configuration, all lockable sections of the stroller are preferably locked (at least those components intended for carrying and transporting the child). The "stack configuration," on the other hand, is a more compact configuration compared to the "usage" configuration. In the "stack configuration," lockable sections may or may not be locked. When the stroller is placed on the ground in the "stack configuration" (in a way that minimizes its height, if multiple options exist), the maximum height of the stroller is [MEISSNER BOLTE M / CUU-404-PC 4].

[0018] A maximum of 50%, preferably a maximum of 20%, or possibly a maximum of 12% of the height of the stroller in its operating configuration (if multiple operating configurations are possible, for example with a height-adjustable handlebar, this should refer to at least one operating configuration, preferably one at maximum height). In the stowed configuration, in particular, no child can be placed in the child restraint or at least cannot be transported (by rolling).

[0019] In general, it is not excluded that an even more compact configuration can be set than a (first) storage configuration, or that a second storage configuration is possible in which, for example, the wheels and possibly frame sections are also tilted around a horizontal axis (in the second storage configuration, where horizontal refers to the orientation of the tilting axis in the usage configuration).

[0020] The lower slide section can have a lower end that is rotatably connected to the base frame (in particular directly) about a lower axis. The lower slide section can have an upper end that is rotatably connected to the upper slide section (in particular directly) about an upper axis.

[0021] This allows the lower and upper slide sections to be moved against each other in a simple way.

[0022] The child reception facility may include a third area. The second area may have a proximal end that can be rotatably connected to the third area (directly).

[0023] The second region may have a distal end that can be rotatably connected to the first region (directly). Preferably, the proximal end of the second region is rotatable about a proximal axis that, in the operating configuration, is preferably located vertically above a level of the lower axis and / or below a level of the upper axis. The distal end of the second region is preferably rotatable about a distal axis that, in the operating configuration, is preferably located vertically above a level of the lower axis and / or below a level of the upper axis. MEISSNER BOLTE M / CUU-404-PC 5

[0024] An axis (any axis) can be defined as a physical axis, for example comprising a rod or a pair of projections (pins), but this is not mandatory.

[0025] The movement of the upper slide section relative to the lower slide section preferably comprises a (possibly pure) rotational movement. Alternatively, the movement of the upper slide section relative to the lower slide section can be a (possibly pure) translational movement. A movement that is both rotational and translational (superimposed, sequential, or phased superimposed and phased sequential) is also possible.

[0026] The first area can be rotatably movable (especially purely rotatably) relative to the second area. Furthermore, the first area can be translationally movable (possibly purely translationally) relative to the second area. It is possible that the first area is both rotatably and translationally movable relative to the second area (superimposed, sequentially, or phased superimposition and phased sequential movement).

[0027] Insofar as relative movements are mentioned, this is intended to mean in particular that the corresponding structures / sections are completely movable relative to each other and / or move relative to each other in an area where they are connected to each other (for example, overlapping and / or via a joint).

[0028] In one embodiment, the upper slide section can seamlessly continue the lower slide section (without kinking) in a continuous operating configuration. Alternatively or additionally, in the operating configuration, the first and second sections can enclose at least substantially an angle of 180° (measured at a junction between the first and second sections) (in side view). "Substantially 180°" refers in particular to a 180° angle with a maximum deviation of ± 10°, preferably ± 5°.

[0029] Insofar as an angle between sections / structures of the stroller, particularly the child restraint system, is mentioned, the respective angle should be 0 or close to 0 when the sides facing a child potentially in the stroller are directly or almost directly adjacent to (or pointing towards) each other. The respective angle should be specifically defined as MEISSNER BOLTE M / CUU-404-PC 6

[0030] 360° (or close to 360°) is considered to occur when the sides facing away from a child potentially in the stroller are directly or almost directly adjacent to (or pointing towards) each other. For example, an angle between push bar sections may be 0° (or close to 0°) when those sides directly or almost directly adjacent are those which, in the configuration of use, point (at least approximately) in the same direction as the sides of the child restraint facing the child potentially in the stroller; and 360° (or close to 360°) when those sides directly or indirectly adjacent are those which, in the configuration of use, point (at least approximately) in the same direction as the sides of the child restraint facing away from a child potentially in the stroller.

[0031] In the stowable configuration, the upper slide section is preferably angled relative to the lower slide section, preferably such that the angle is less than 180°, preferably less than 90°, and even more preferably less than 20°, or possibly 0°.

[0032] In the stowable configuration, the first area can form an angle with the second area of ​​greater than 180°, preferably greater than 270°, even more preferably greater than 350°, possibly 360° (so that the surfaces of the first and second areas facing away from the child in relation to the usage configuration face each other).

[0033] In this embodiment, the upper slide section can perform a first rotation relative to the lower slide section when converting from the operating configuration to the stow configuration. Alternatively or additionally, the first section can perform a second rotation relative to the second section when converting from the operating configuration. Preferably, the first and second rotations differ from each other (for example, such that the second rotation only begins once the first rotation has already started, i.e., after a rotation angle of, for example, at least 5° or at least 15° has been completed). It would also be conceivable that the total rotation (total rotation angle) of the first section relative to the second section is less (or greater) than the total rotation of the upper slide section relative to the lower slide section when transitioning from the operating configuration to the stow configuration.Specifically, the total rotation angles can be identical, for example MEISSNER BOLTE M / CUU-404-PC 7.

[0034] each shall be 180°. When referring to rotation angles, this refers in particular to a delta between an initial position and an end position (especially between a position in operating configuration and a position in stowing configuration), preferably a maximum possible (respective) rotation angle.

[0035] In a preferred embodiment, the upper slider section is rotatable relative to the lower slider section in a first direction during conversion from the operating configuration to the stow configuration. Alternatively or additionally, the first section is rotatable (or rotated) relative to the second section in a second direction (opposite to the first direction) during conversion from the operating configuration to the stow configuration.

[0036] Specifically, the direction of rotation of the corresponding sections can be reversed. Preferably, the upper section of the handlebar rotates counterclockwise relative to the lower section when viewed from the left side of the stroller, and the first section rotates clockwise relative to the second (where, in this context, the second section, or lower section of the handlebar, is considered stationary). Especially when the corresponding movement differs (particularly the opposite direction of rotation), an extremely compact position can be easily achieved. In particular, the corresponding axes of rotation can be moved away from each other, which reduces the overall space requirement (compared to a case where the axes of rotation, with their correspondingly necessary structural features, are located close together in the stowed configuration).In specific embodiments, the lower slider section and the upper slider section, in the stowed configuration, enclose an angle of at most 30°, in particular at most 15°. Alternatively or additionally, the first section and the second section, in the stowed configuration, enclose an angle of more than 330°, in particular more than 345°.

[0037] Preferably, the child reception facility includes a buttocks area and a back area. The buttocks area may include a third area.

[0038] The back area can include the first area and the second area.

[0039] The child restraint system is preferably designed as a child seat. MEISSNER BOLTE M / CUU-404-PC 8

[0040] The child restraint system can have a leg section for the child's legs, which can optionally be rotated relative to the buttocks area. Alternatively, the child restraint system may not have a leg section (in which case at least parts of the child's thighs can rest on the buttocks area). In one embodiment, the child restraint system does not have a leg section that can be pivoted relative to the buttocks area.

[0041] The first section and / or second section (possibly the back section) may have a smaller transverse extent (extension in the lateral direction or in the left-right direction) (preferably at least 2% smaller and / or at most 20% smaller) than the slider. Preferably, the first section and / or second section fit between the left slider strut and the right slider strut, in particular such that the first section and / or second section can be moved at least partially, possibly completely, through the space between the left slider strut and the right slider strut (or at least could be moved if they are at least partially restrained by another component, i.e., not the left or right slider strut).

[0042] Preferably, the upper and lower slide sections are directly connected. In general, the upper and lower slide sections can be spaced less than 10 cm or less than 4 cm apart in at least one configuration, particularly a service configuration.

[0043] The first end and second end can form at least one joint, in particular a right-hand joint on the right side of the slide and a left-hand joint on the left side of the slide. Alternatively or additionally, an indirect connection (for example, via an intermediate piece) can be made, whereby two joints can be present per slide strut.

[0044] Alternatively or additionally, the first and second areas can be directly connected. Generally, the first and second areas can be less than 10 cm apart, less than 4 cm apart, or even 0 cm apart. Specifically, the first and second areas can be separated by (at least) one joint (possibly formed by the areas themselves), or possibly two joints on either side. An indirect MEISSNER BOLTE M / CUU-404-PC 9

[0045] Connection (for example by means of at least one intermediate joint piece) is possible.

[0046] The upper and / or lower valve sections, in particular the right and left valve struts, may be designed, at least partially, as tube(s) and / or profile(s). Alternatively or additionally, the first and second sections may each comprise a plate.

[0047] Specifically, the first and / or second and / or third area can comprise at least one textile (cover or soft good), in particular a common textile for the first and second area and / or the second and third area and / or the first, second, and third area. The textile (soft good) can preferably encase the (respective) panel. The textile can be attached to the slider and / or the base frame.

[0048] At least one additional textile (soft good), for example for a canopy, may be provided, which may optionally be connected to the textile of, for example, the first area.

[0049] In particular, sections of textiles can form the tensile force described below. This allows for simple and effective adjustment.

[0050] Preferably, a locking means, in particular comprising or formed by a stop, is provided that prevents the angle between the first and second regions from becoming smaller than 160°, preferably smaller than 175°, optionally smaller than 180°. For this purpose, the (respective) joint can be eccentric with respect to the plane defined by the first and second regions, and / or the edges of the first and second regions can abut each other. The locking means can have one or more locking devices (in particular stops).

[0051] Preferably, the stroller includes a locking device that locks the upper handle section and the lower handle section together in the operating configuration and / or that locks the lower handle section and the chassis together in the operating configuration, wherein the stroller, in particular the handle (preferably the upper MEISSNER BOLTE M / CUU-404-PC 10

[0052] The sliding section may include a release mechanism for releasing the locking device. In addition to or as an alternative to locking the upper sliding section against the lower sliding section and / or the lower sliding section against the underframe, the locking device may optionally also lock at least one component of the underframe, for example, at least one front wheel strut and / or at least one rear wheel strut, together in its operating configuration.

[0053] A (manual) release mechanism preferably comprises an actuating button and / or actuating lever and / or actuating slide. In a specific embodiment, at least one release mechanism can be arranged laterally on the upper slide section, preferably at a distal end of handle sections extending upwards and / or forwards (possibly obliquely upwards) in the operating configuration. According to the embodiment, a release mechanism, in particular a release button (push button), is provided on each such handle section, and these preferably must be actuated simultaneously to release a locking mechanism.

[0054] To make the release mechanism easy to identify, it can have a different color than adjacent sections of the stroller; for example, the release mechanism can be white and the adjacent section black.

[0055] The (respective) optional handle can be rotated relative to a central section of the upper push bar section in order to make the stroller even more compact (in the storage configuration).

[0056] Preferably, the upper slide section has a slide end section (in particular comprising a transverse segment) (which in particular does not include the connection of the upper slide section to the lower slide section). The first section may comprise a child intake device end section (which preferably does not include the connection of the first section to the second section), wherein the first section, in particular the child intake device end section, is connected to the upper slide section, in particular the slide end section (the transverse segment), by means of connecting elements, in particular a tension element (optionally comprising one or more tension elements). MEISSNER BOLTE M / CUU-404-PC 11

[0057] Preferably, the connecting element, in particular the tensioning element, comprises a planar structure (for example, formed by or comprising a textile) and / or at least one strap. Specifically, (exactly) two lateral strap sections and (exactly) two lateral planar structures can be provided.

[0058] Preferably, the sliding end section approaches the lower axle during conversion from the operating configuration to the stow configuration. Alternatively or additionally, the upper axle approaches the at least two rear wheels. Preferably, the connecting element, in particular the traction element, drives the first section, in particular the child restraint end section, to move in the direction of the lower axle and / or the proximal axle and / or the rear wheels. In particular, the traction element pulls the first section (in particular the child restraint end section) in the direction of the lower axle, so that, further preferably, the first section is driven to move, in particular to fold around the distal axis, relative to the second section (to shorten the effective length of a combination of the first section and the second section, in particular the back section).The length is, in particular, a (maximum) extent in a direction perpendicular to the transverse extent of the respective structure.

[0059] The above-mentioned problem is further solved in particular by a method for converting a stroller, especially of the type above, from a usage configuration into a storage configuration, wherein the stroller comprises a chassis, a push bar with a lower push bar section and an upper push bar section, and a child receiving device with a first area and a second area, wherein the method comprises the following steps:

[0060] - preferably actuating a release mechanism to release a locking device,

[0061] - Moving, especially flaps, the upper slide section relative to the lower slide section,

[0062] the movement of the upper slide section relative to the lower slide section causes the first section to move relative to the second section. MEISSNER BOLTE M / CUU-404-PC 12

[0063] Further procedural aspects arise from the above and subsequent description of the stroller, whereby functional or purpose-oriented specifications can be concretely implemented as procedural characteristics (steps). For example, if it is stated in connection with the stroller that one structure is rotatable relative to another structure, this can mean, in particular for the procedural aspect, that such a rotation actually takes place.

[0064] The wheels, in particular the at least one rear wheel (or at least or exactly two rear wheels), can be rotatable, especially for further compacting the stroller, particularly around an axis that preferably compacts at least approximately parallel to an extension of the rear wheel strut. Such rotation can be coupled to a rotation of the upper handle section relative to the lower handle section and / or to a rotation of the first section relative to the second section. Alternatively, such rotation of the wheels (especially rear wheels) can be carried out independently (for example, in a subsequent compaction step).

[0065] In particular, the rear wheels can be rotated for compaction by turning an associated handle on the upper slider section.

[0066] In the stow configuration, at least one front wheel (especially at least or exactly two front wheels) can be located between the two rear wheels.

[0067] The back area is preferably designed to accommodate the child's back and head. The buttocks area is preferably designed to accommodate the child's buttocks (and possibly at least parts of the child's thighs).

[0068] The first and / or second and / or third area can each have a base plate made of a dimensionally stable material (for example, a polymer, in particular a non-porous polymer). Alternatively, the first and / or second and / or third area can be formed by a (particularly stretched) textile, the textile being stretched, for example, in a corresponding frame assigned to the respective area. MEISSNER BOLTE M / CUU-404-PC 13

[0069] Generally, a sub-frame may be provided to synchronize the individual components of the stroller during the folding process.

[0070] Further embodiments are described in the dependent claims.

[0083] Fig. 12 shows a configuration starting from the stowing configuration according to Fig. 11, wherein the rear wheels of the stroller are rotated for further compaction; and

[0084] Fig. 13 shows an oblique view of the configuration according to Fig. 12.

[0085] In the following description, the same reference numbers are used for identical and equivalent parts.

[0086] Figures 1 and 2 show oblique views of a stroller 100 according to the disclosure. The stroller may have a canopy 153, which is extended in Figure 1 and retracted (by rotation) in Figure 2. The stroller includes a child restraint 140, comprising a backrest 141 and a seat 142.

[0087] Furthermore, the stroller 100 comprises a chassis 110, comprising at least one (specifically exactly two) front wheel stays (2) 111 and at least one (specifically exactly two) rear wheel stays (2) 112. A front wheel 113 is arranged on each front wheel stay 111. The front wheel can be rotatable about a vertical axis (in the operating configuration) for maneuvering the stroller. A rear wheel 114 is arranged on each rear wheel stay. The rear wheel 114 can be fixed (in the operating configuration), and in particular, not rotatable. Such a fixation is preferably releasable, so that the rear wheel can be rotated about an axis (which preferably extends at least approximately parallel to the length of the rear wheel stay) for compaction.

[0088] Figures 1 and 2 also show a slider 120, which has a right slider arm 121 and a left slider arm 122. Each slider arm 121, 122 can have a lower slider section 123 and an upper slider section 124. A release mechanism 109 (specifically comprising two release buttons) is visible at the top of the stroller according to Figure 1. MEISSNER BOLTE M / CUU-404-PC 15

[0089] The stroller 110 can also have a harness system 101 and a luggage compartment 102.

[0090] The upper slide section 124 includes a slide end section 129, which in turn may have a transverse segment 130 (see Fig. 3).

[0091] The conversion of the stroller from the usage configuration shown in Figures 1 and 2 to a storage configuration is now described with reference to Figures 3 ff. According to Figure 3, the upper handle section 124 is pivoted relative to the lower handle section 123, so that the upper handle section 124 and the lower handle section 123 do not (as in Figures 1 and 2) extend each other at least substantially linearly. A configuration corresponding to Figure 3 is also shown in Figure 4 (where the canopy 153 is folded). Figure 5 shows the storage configuration.

[0092] The exact process of converting the stroller into its stowable configuration can be better understood with reference to Figures 6 ff., since elements such as the padding and canopy have been omitted in Figures 6 to 11. Figures 6 and 7 initially show the stroller 110 in its standard configuration.

[0093] The child receiving device 140 is divided by a proximal axis 146 and a distal axis 147 into a first section 143, a second section 144, and a third section 145. The first and second sections 144, 145 are formed by the back section 141. The third section 145 is formed by the buttocks section 142. Specifically, the second section is rotatably connected to the third section 145 at a proximal end 148 about the proximal axis 146. The transverse dimension 150 of the back section is preferably smaller (narrower) than the distance between the right sliding strut 121 and the left sliding strut 122 (this also applies in particular to a potentially increased transverse dimension of the back section if a soft good is arranged on the base plate shown in Fig. 6).

[0094] As can be seen in Figs. 6 to 11, the first area 143, the second area 144 and the third area 145 can each have a base plate (which is not mandatory, however, since, for example, corresponding areas can also be defined by a stretched textile and are accordingly described below in MEISSNER BOLTE M / CUU-404-PC 16).

[0095] The rotations described can be achieved by rotating frame elements intended for clamping.

[0096] Specifically, the pediatric admission facility 140 comprises a third section 145, wherein the second section 144 has a proximal end 148 that is rotatably connected to the third section 145. Furthermore, the second section 144 has a distal end 149 that is rotatably connected to the first section 143 (see Fig. 6).

[0097] According to Figures 8 to 11, the front wheel struts 111 and rear wheel struts 112 are preferably rotatable about a chassis axle 115. The chassis axle 115 preferably has a distance from the lower axle 125, which is not mandatory.

[0098] A base plate (plate) of the first area is provided with reference numeral 151 in Fig. 7. A reference (soft good) 152 can be seen, for example, in Fig. 2.

[0099] In addition to the axes 146 and 147 already mentioned, axes 125 and 126 are also shown in Fig. 7, specifically a lower axis 125 and an upper axis 126. The upper slide section 124 can be rotated about the upper axis 126 relative to the lower slide section 123. The (entire) slide, or the lower slide section 123, can be rotated about the lower axis 125 relative to the base 110. Specifically, a lower end 127 of the lower slide section 123 is rotatably connected to the base 110 about the lower axis 125; and an upper end 128 of the lower slide section 124 is rotatably connected to the upper slide section 124 about the upper axis 126.

[0100] Figure 8 shows a side view of the stroller, analogous to Figures 6 and 7. The release mechanism 109 is again visible here (at one upper end of the stroller in its operating configuration).

[0101] The stowing process can be controlled by rotating the upper slider section 124 relative to the lower slider section 123. For this purpose, the upper slider section 124 and the lower slider section 123 can be connected to the child restraint system via strap sections and / or soft goods. Furthermore, a linkage 106 (see Fig. 8) can control the movements. MEISSNER BOLTE M / CUU-404-PC 17

[0102] The linkage 106 can transmit and / or guide the movement. For this purpose, the linkage 106 can have joints 107 (see Figs. 9 and 10). In particular, the linkage 106 can be pivotally connected to the child-receiving area, especially the third area 145, the (respective) rear wheel stays, the (respective) front wheel stays, and the upper and lower slider sections. It should be noted here that the joint 107a, with which the linkage 106 is articulated to the rear wheel stay (see Fig. 10), can only be understood schematically. In reality, this joint 107a can be fixed to the respective rear wheel stay or can be concealed by the rear wheel stay in the side view according to Fig. 10. Therefore, the positioning of the joint 107a, and in particular any changes to this positioning, can deviate from the representation in the figures (and therefore also the relative angle between the front wheel stay and the rear wheel stay).The front wheel strut and the rear wheel strut are preferably pivoted relative to each other via the joints 107a, 107b and 107c.

[0103] Starting from Fig. 8, the pram according to Fig. 9 is already partially converted into its stowable configuration. In particular, the upper handle section 124 has been moved towards the lower handle section 123. In the intermediate configuration according to Fig. 9, the first section 143 is not yet rotated relative to the second section 144 (but lies on a common plane with it). Therefore, the effective length 156 of the back section 141 (which is formed by the first section 142 and the second section 144) has not yet been reduced.

[0104] If (see Fig. 10) the upper slider section 124 is rotated further relative to the lower slider section 123, the first section 143 is also rotated relative to the second section 144, but the direction of rotation is exactly opposite to the direction of rotation of the upper slider section 124 with respect to the lower slider section 123. Specifically, it can be seen that the distal axis 147 is no longer (as in Fig. 7 or in the operating configuration) below the upper axis 126 (relative to a given level), but above it. According to a general principle, the upper axis 126 changes its height relative to the distal axis 147, in particular such that the axis 147 is initially below the level of the axis 126 and, as the stroller is moved into its stowable configuration, is above it at a certain point. This change can occur, in particular, when all the wheels of the stroller are (still) in contact with the ground.MEISSNER BOLTE M / CUU-404-PC 18.

[0105] Furthermore, as can be seen in Fig. 10, the effective length 156 of the back area 141 has been reduced.

[0106] In Fig. 10 a blocking means 154 is further shown, which comprises two complementary stops and prevents the first area 143 and the second area 144 from being rotated differently from Fig. 8 to 10 (i.e. in the other direction).

[0107] Figure 11 finally shows the stowage configuration. In this configuration, the upper slider section 124 and the lower slider section 123, as well as the first section 143, the second section 144, and the third section 145, are folded together (only indirectly visible in Figure 11, as they are obscured by other parts, especially the slider). In this configuration, the first and second sections 143 and 144 point away from each other. Furthermore, the second section 144 and the third section 145 point towards each other.

[0108] For further compaction (see Figs. 12 and 13), handles 105 (see Figs. 12, 13) can be pivoted and / or the rear wheels 114 can be pivoted. Preferably, the rear wheels 114 are pivoted by pivoting the handles 105.

[0109] The transfer process for moving the stroller into its stowable configuration can preferably be initiated by actuating the release mechanism 109 (or, more specifically, by simultaneously actuating the corresponding actuating buttons). Such actuation releases a locking device for locking the stroller, in particular the handlebar and the chassis 110.
