[0002] This application claims priority to U.S. Provisional Application 62 / 967,466, filed January 29, 2020, entitled “STROLLERHAVING COMPACT FOLDING AND SUSPENSION SYSTEM”, under 35 U.S.SC §119(a), the disclosure of which is incorporated herein by reference in its entirety. Technical Field

[0003] The subject matter described herein relates to several different embodiments of a stroller with a foldable frame. Background Technology

[0004] Strollers offer multiple uses, such as transporting children and carrying objects. The ability to use a stroller in a variety of conditions enhances convenience and practicality. For example, some strollers are configured to allow users to carry at least one child while jogging. Such jogging strollers may include a suspension system that helps ensure a smoother ride for the child. While jogging strollers offer many benefits, one drawback is their relatively large size, including when in a folded or collapsed configuration. Smaller and more compact folding stroller configurations make transportation easier, such as in a car or on public transport, and also enable improved storage. Summary of the Invention

[0005] The present subject matter includes various embodiments of stroller assemblies comprising a foldable frame and a suspension system. In one aspect, the stroller assembly may include a foldable frame assembly having a top frame including a handle. The foldable frame assembly may also include a bottom frame pivotally connected to the top frame such that the top frame is allowed to pivot along the longitudinal plane of the foldable frame assembly. The foldable frame assembly can form a folded configuration as the top frame pivots toward the bottom frame, and an extended configuration as the top frame pivots away from the bottom frame. The foldable frame assembly may also include a first pillar assembly pivotally connected to the bottom frame at a first angled joint. The first pillar assembly may include a first rear wheel axle, and the first angled joint may include a first rotation axis angled relative to the longitudinal plane, such that when the top frame pivots toward the bottom frame to form the folded configuration, the first rear wheel axle pivots toward the longitudinal plane.

[0006] In some variations, one or more of the following features may be optionally included in any feasible combination. The foldable frame assembly may also include a second strut assembly pivotally connected to the bottom frame at a second angled joint. The second strut assembly may include a second rear axle, and the second angled joint may include a second rotation axis angled relative to the longitudinal plane, such that when the top frame pivots toward the bottom frame, the second rear axle pivots toward the longitudinal plane. The first rotation axis may form a first angle with the longitudinal plane, which may be approximately 70 degrees to approximately 80 degrees. The second rotation axis may form a second angle with the longitudinal plane, which may be approximately 70 degrees to approximately 80 degrees. The first and second rotation axes may each extend along different planes.

[0007] The foldable frame assembly may further include a first suspension system, which includes a first shock absorber and extends between the top frame and the first strut assembly. The foldable frame assembly may also include a second suspension system, which includes a second shock absorber and extends between the top frame and the second strut assembly. The first suspension system may be connected to the first strut assembly via a first ball joint enabling three-dimensional pivoting, and the first suspension system may be connected to the top frame via a second ball joint enabling three-dimensional pivoting. Three-dimensional pivoting allows the first suspension system and the first strut assembly to pivot toward the longitudinal plane as the top frame pivots toward the bottom frame.

[0008] A first rear axle can be configured to connect to a first rear wheel, and a second rear axle can be configured to connect to a second rear wheel. When the foldable frame assembly is in a folded configuration, a first track can be formed between the first rear wheel and the second wheel; when the foldable frame assembly is in an extended configuration, a second track can be formed between the first rear wheel and the second wheel. Furthermore, the second track can be longer than the first track. When the foldable frame assembly is in an extended configuration, the first wheel can be positioned parallel to the second wheel; when the foldable frame assembly is in a folded configuration, the first wheel can be positioned at an angle relative to the second wheel.

[0009] In some embodiments, the stroller assembly may also include a material seat portion connected to the foldable frame assembly.

[0010] In another related aspect of the present topic, a method includes a folding configuration of a foldable frame assembly forming a stroller assembly. For example, the method may include pivoting a top frame of the foldable frame assembly toward a bottom frame of the foldable frame assembly along a longitudinal plane. The method may also include, as a result of pivoting the top frame toward the bottom frame, pivoting a first strut assembly and a first suspension assembly toward a longitudinal plane. Additionally, the method may include, as a result of pivoting the top frame toward the bottom frame, pivoting a second strut assembly and a second suspension assembly toward a longitudinal plane.

[0011] In some variations, one or more of the following features may be optionally included in any feasible combination. The first strut assembly may pivot independently of the second strut assembly. The first strut assembly may be pivotally connected to the bottom frame at a first angled joint, and the first strut assembly may include a first rear wheel axle. The first angled joint may include a first rotation axis angled relative to the longitudinal plane, such that the first rear wheel axle can pivot toward the longitudinal plane as the top frame pivots toward the bottom frame.

[0012] A first axis of rotation may form a first angle with the longitudinal plane, the first angle being approximately 70 degrees to approximately 80 degrees. A first suspension system may include a first shock absorber and extend between the top frame and the first strut assembly. The first suspension system may be connected to the first strut assembly via a first ball joint enabling three-dimensional pivoting, and the first suspension system may be connected to the top frame via a second ball joint enabling three-dimensional pivoting. Three-dimensional pivoting allows the first suspension system and the first strut assembly to pivot toward the longitudinal plane when the top frame pivots toward the bottom frame.

[0013] The first rear axle can be configured to connect the first rear wheel to the first pillar assembly. The stroller assembly may also include a material seat portion that connects to the top frame and the bottom frame.

[0014] Details of one or more variations of the subject matter described herein are set forth in the accompanying drawings and the following description. Other features and advantages of the subject matter described herein will become apparent from the specification, the accompanying drawings, and the claims. The claims following the invention are intended to define the scope of the protected subject matter. Attached Figure Description

[0035] The current subject matter relates to several different embodiments of a foldable stroller with a foldable frame, the foldable frame including folding features that enable the foldable stroller to be folded and collapsed into a compact configuration efficiently and effectively. In some embodiments, the foldable stroller may include a suspension system capable of effectively absorbing shocks during use of the foldable stroller. For example, the foldable stroller can switch between an extended configuration (e.g., in an unfolded state) and a retracted configuration (e.g., in a folded state). Additionally, the extended state allows for the transport of a child (e.g., positioning along the material seat portion of the foldable stroller), while the retracted configuration allows for the storage of the foldable stroller. The foldable stroller described herein can be used in a variety of different ways, such as for carrying a child being pushed by a user who is running or walking. Other uses of the stroller are also within the scope of the invention.

[0036] In some embodiments, the foldable stroller includes a foldable frame assembly that includes at least one angled connector assembly that helps to enable the foldable stroller to form an improved compact configuration, for example, compared to at least some other currently available strollers, as will be described in more detail below.

[0037] Figures 1A to 1R An embodiment of a foldable stroller 100 consistent with the current topic is shown. Figure 1A As shown in Figure 1J, the foldable stroller 100 may include a foldable frame assembly 110, which includes a top frame 112 pivotally connected to a bottom frame 114. Figure 1C As shown, the bottom frame 114 may include a frame crossbar 109 and a pair of bottom side bars 117. Figure 1C As shown, each of the bottom side bars 117 may include a first end connected to both ends of the frame crossbar 109. The bottom side bars 117 may also be connected to each other at a second end of each bottom side bar 117, as shown below. Figure 1C As shown in Figures 1E to 1J, the bottom frame 114 can be connected to the front wheel 116. For example, the front wheel 116 can be connected to the second end of the bottom side bar 117.

[0038] In some embodiments, the top frame 112 may include a pair of top side bars 107, each connected to one end of the handle 111, such as... Figure 1CAs shown. The handle 111 can be configured to allow a user to push and / or steer the foldable stroller 100. In some embodiments, the handle 111 can be connected to a top side bar 107 via a handle pivot joint 103, which allows the handle 111 to form more than one configuration relative to the top side bar 107, for example, forming more than one angle between the handle 111 and the top side bar 107. For example, the handle 111 can form an angle between approximately 180 degrees and approximately 90 degrees relative to the top side bar 107. A handle support structure 105 can extend between the handle pivot joints 103 to help provide structural support for the top frame 112 of the foldable frame assembly 110.

[0039] The foldable frame assembly 110 may include a pair of frame joints 115 that pivotally connect the top frame 112 to the bottom frame 114 and facilitate movement of the foldable frame assembly 110 between an unfolded configuration, as shown in Figures 1E and 1H, and a folded configuration, as shown in Figures 1G and 1J. As shown in Figures 1F and 1I, the top frame 112 and the bottom frame 114 may pivot toward each other along a longitudinal plane L (with the pivot point being the frame joint 115) to form a retracted configuration. The frame joints 115 may include and / or be controllable by a releasable locking mechanism that allows a user to selectively pivot the foldable frame assembly 110 to a folded configuration and / or an unfolded configuration. Frame joint support structures 106 may extend between the frame joints 115, such as Figure 1C As shown, this helps to provide structural support for the foldable frame component 110, for example, when in the unfolded configuration.

[0040] like Figure 1A As shown in Figure 1J, the foldable stroller 100 may include two support assemblies 120 connected to a bottom frame 114, each support assembly 120 being connected to the bottom frame 114 via an angled connector assembly 122. In some embodiments, each support assembly 120 may be connected to a top frame 112 via a suspension assembly 125, such as... Figure 1A As shown in -1J. As will be described in more detail below, each of the support components 120 is connected to the top frame 112 and the bottom frame 114, enabling the foldable stroller 100 to provide efficient steering and comfortable passenger seating, while achieving an improved compact configuration, for example, compared to at least some currently available jogging and / or foldable strollers.

[0041] like Figure 1B As shown, the foldable frame assembly 110 may include a first strut assembly 120a, which is connected to the bottom frame 114 via a first angled joint assembly 122a and to the top frame 112 via a first suspension assembly 125a. Also as... Figure 1BAs shown, the foldable frame assembly 110 may include a second strut assembly 120b, which is connected to the bottom frame 114 via a second angled joint assembly 122b and to the top frame 112 via a second suspension assembly 125b. The first strut assembly 120a and the second strut assembly 120b may include the same or similar functions and features. Thus, the description of the strut assembly 120 is applicable to the description of the first strut assembly 120a and the second strut assembly 120b. Similarly, the first angled joint assembly 122a and the second angled joint assembly 122b may include the same or similar functions and features. Thus, the description of the angled strut assembly 122 is applicable to the description of the first angled joint assembly 122a and the second joint assembly 122b. Furthermore, the description of the suspension assembly 125 is applicable to the description of the first suspension assembly 125a and the second suspension assembly 125b.

[0042] like Figure 1B As shown, the strut assembly 120 may include a structural support member 130 extending between a first support end 131 and a rear axle 132. The first support end 131 may be formed as part of an angled joint assembly 122, such as... Figure 1K and Figure 1L As shown. The rear axle 132 can be configured to connect the rear wheel 134 thereto, as... Figure 1B As shown. In some embodiments, the structural support 130 may have a curved shape along its length, for example as Figure 1B As shown.

[0043] like Figure 1B and Figure 1Q As shown, the first angled connector assembly 122a can be positioned at an angle relative to the second angled connector assembly 122b. For example, the first angled connector assembly 122a may have a first rotation axis 135a that is not parallel to and has a different axis from the second rotation axis 135b of the second angled connector assembly 122b. In some embodiments, the first rotation axis 135a and the second rotation axis 135b may extend along different planes. Figure 1B and 1Q As shown, the first rotation axis 135a and the second rotation axis 135b can intersect the longitudinal plane L of the foldable stroller 100 at an angle θ of approximately 70 to approximately 80 degrees. As will be described in more detail below, the aforementioned angled positioning of the first angled connector assembly 122a and the second angled connector assembly 122b allows the first support assembly 120a and the second support assembly 120b to pivot towards each other (e.g., towards the longitudinal plane L) and towards the top frame 112, respectively, when the foldable stroller 100 is moved to the folded configuration, as shown in Figures 1E to 1J. Figure 1B As shown, the longitudinal plane L can extend along the longitudinal axis of the foldable frame assembly 110.

[0044] As shown in Figures 1G and 1J, when the foldable frame assembly 110 is in a folded configuration due to the inward pivoting of the strut assembly 120 and suspension assembly 125 toward the longitudinal plane L, the strut assembly 120 and suspension assembly 125 can be positioned, or at least substantially positioned, within the boundary formed at least by the top side bar 107 of the top frame 112 and the handlebar 111. Thus, in the folded configuration, the maximum width of the foldable stroller 100 can be defined by and / or not greater than the distance between the outer sides of the top side bars 107 of the top frame 112, as shown in Figure 1J. Additionally, when the foldable frame assembly 110 is in the folded configuration, the rear wheels 134 can be positioned at least substantially adjacent to the front wheels 116, as shown in Figure 1J. For example, when the foldable frame assembly 110 is in the unfolded configuration, the rear wheels 134 can be spaced approximately 22 inches to approximately 25 inches, such as approximately 23.5 inches. Furthermore, when the foldable frame assembly 110 is in the folded configuration, the rear wheels 134 can be spaced approximately 10 inches to approximately 12 inches, for example, approximately 11 inches. The reduction in the overall width of the foldable stroller 100 between its extended and folded configurations allows the foldable stroller 100 to achieve an effective compact size, for example, for storage and transport in a compact configuration.

[0045] In some embodiments, the foldable stroller 100 may have a height of approximately 43 inches in its unfolded configuration (as shown in FIG. 1E) and approximately 29 inches in its folded configuration (as shown in FIG. 1G). Additionally, the foldable stroller 100 may have a length of approximately 39 inches (e.g., front-to-back distance) in its unfolded configuration (as shown in FIG. 1E) and approximately 16 inches in its folded configuration (as shown in FIG. 1G). Furthermore, the foldable stroller 100 may have a width of approximately 25 inches (e.g., side-to-side distance) in its unfolded configuration (as shown in FIG. 1H) and approximately 17 inches in its folded configuration (as shown in FIG. 1J). Other configurations and dimensions of the foldable stroller 100 are also within the scope of this invention.

[0046] At least some currently available strollers include a crossbar between a set of wheels, such as between a set of rear wheels, to help fix the position of the rear wheels relative to each other. The foldable stroller 100 of the present invention does not include a crossbar or structure extending between the rear axle 132 or the rear wheels 134. Instead, the foldable stroller 100 may include a hub crossbar 113 extending between angled joint assemblies 122, such as... Figure 1BAs shown, and can provide structural support and stability to the foldable stroller 100, as well as other benefits associated with the foldable stroller 100. For example, the hub crossbar 113 allows the strut assemblies 120, such as the first strut assembly 120a and the second strut assembly 120b, to move and pivot independently of each other. This independent movement and pivoting toward the longitudinal plane L allows the foldable stroller 100 to form a desired compact configuration (e.g., the rear wheels 134 can move closer to each other) and achieves smooth and stable steering and movement (e.g., due to the presence of the suspension system 125), as will be further described below. When maintaining the extended configuration, the hub crossbar 113 also prevents the strut assemblies 120 from pivoting toward each other (e.g., toward the longitudinal plane L).

[0047] Figure 1K-1P An embodiment of an angled connector assembly 122 of a foldable stroller 100 is shown, wherein Figure 1L-1P This includes at least a portion of a concealed, angled joint assembly 122. The angled joint assembly 122 allows the corresponding support assembly 120 to be aligned (including a series of alignments) with at least the bottom frame 114, thereby enabling the foldable stroller 100 to achieve smooth and stable steering and movement. Figure 1K-1Q As shown, the angled joint assembly 122 may include a hub bracket 142 extending from the bottom frame 114, for example, from the frame crossbar 109. The hub bracket 142 may include a pair of parallel extensions 144 spaced apart to provide a hub bushing 146, including a hub shaft 149 positioned therebetween. Figure 1M As shown. The first support end 131 of the strut assembly 120 can be connected to the hub bushing 146 and is also positioned between the parallel extensions 144, for example as... Figure 1K and Figure 1L As shown, this allows the support assembly 120 to pivot along the hub shaft 149 and remain aligned with the hub bracket 142. For example, when the hub bushing 146 is connected to the hub bracket 142, the hub shaft 149 is collinear with the rotation axis 135 of the angled joint assembly 122, thus allowing the support assembly 120 to pivot toward the longitudinal plane L of the foldable stroller 100 when the foldable frame assembly 110 is transformed into a foldable configuration.

[0048] like Figure 1N and Figure 1PAs shown, the pivot bolt assembly 150 may extend along the hub axle 149 to provide a stable axis of rotation, for example, to enable the strut assembly 120 to maintain a position and / or achieve a series of positions relative to the bottom frame 114. Thus, the rear wheels 134 connected to the strut assembly 120 may be maintained in a desired alignment and / or a series of alignments relative to the bottom frame 114 and / or the longitudinal plane. For example, at least the angled joint assembly 122, including the hub axle 149 and the axis of rotation, allows the rear wheels 134 to be aligned parallel to each other when the foldable stroller 100 is in the unfolded position. Figure 1B As shown in Figure 1J. Additionally, when the foldable stroller is in its folded configuration, the rear wheels 134 can be angled relative to each other.

[0049] As described above, the rotation axes 135 of the first and second angled joint assemblies 122a, 122b are not parallel to each other and are not coaxial, so that the support assembly can pivot toward the longitudinal plane L of the foldable stroller 100 when moved to the folded configuration. This inward pivoting enables a compact folding configuration. Therefore, the angled joint assembly 122 contributes to achieving a compact folding configuration of the foldable stroller 100, as well as to achieving efficient and effective steering and movement of the foldable stroller (e.g., keeping the rear wheels 134 parallel to each other when the foldable stroller 100 is in the extended configuration).

[0050] like Figure 1A As shown, the foldable stroller 100 may include a suspension assembly 125, which may be part of and / or integrated with the foldable frame assembly 110. Figure 1A As shown, the suspension assembly 125 may extend between the top frame 112 and the strut assembly 120. For example, the suspension assembly 125 may pivot relative to the top frame 112 and the strut assembly 120 so that the suspension assembly 125 can pivot toward and away from the longitudinal plane L, respectively, when the foldable stroller 100 changes between a folded configuration and an extended configuration.

[0051] For example, suspension assembly 125 may include a shock absorber 155 extending between two ball joints 157. A first ball joint 157a connects the shock absorber 155 to the top frame 112, and a second ball joint 157b connects the shock absorber 155 to the strut assembly 120, such as... Figure 1A As shown. Figure 1BAs shown, the foldable stroller 100 may include a first suspension assembly 125a extending between a top frame 112 and a first strut assembly 120a, and a second suspension assembly 125b extending between the top frame 112 and a second strut assembly 120b. The first suspension assembly 125a may be the same as or substantially the same as the second suspension assembly 125b, such that the disclosure of the suspension assembly 125 is applicable to the first and second suspension assemblies 125a, 125b. A ball joint 157 connecting a shock absorber 155 to the top frame 112 and the strut assembly 120 allows the shock absorber 155 to move in three dimensions, thereby allowing the strut assembly 120 and the suspension assembly 125 to pivot toward the longitudinal plane L of the foldable stroller 100, as shown in Figures 1H-1J. In this way, the suspension assembly 125 can provide shock absorption (via the damper 155), such as absorbing vibrations caused by the rear wheel 134 traveling on an uneven surface, and allow the strut assembly 120 and the suspension assembly 125 to pivot inward toward the longitudinal plane L of the foldable stroller 100 to help form a compact folding configuration.

[0052] The first and second suspension assemblies 125a and 125b can further enable the first and second strut assemblies 125a and 125b to move independently. For example, movement of the rear wheel 134 associated with the first strut assembly 125a can travel on an uneven surface, causing the associated first shock absorber 155a of the first suspension assembly 125a to activate (e.g., compress) and absorb at least part of the movement of the first strut assembly 120a caused by such travel. Additionally, while the first strut assembly 120a can be moved (e.g., relative to the top frame 112) and the associated shock absorber 155 activated, the second strut assembly 120b can remain stationary (e.g., relative to the top frame 112) and thus the associated second shock absorber 155 deactivated, for example, when the rear wheel 134 associated with the second strut assembly 120b travels on a flat surface. Thus, the movement and damping of the first strut assembly 120a can be independent of the movement and damping of the second strut assembly 120b, thereby providing stable and smooth steering and movement of the foldable stroller 100.

[0053] Figure 1R An embodiment of a material seat portion 190 connected to a foldable frame assembly is shown. The material seat portion 190 provides a seat and support for the passenger (e.g., a child) of the foldable stroller. The material seat portion 190 can be flexible to allow the foldable stroller to fold and unfold into a configuration. Other structural members with multiple different functions may also be connected to the foldable frame assembly, such as a retractable cover 192. Other features and functions associated with the foldable stroller 100 are also within the scope of this invention.
