Description

[0001] Cross-citation of relevant literature

[0002] This invention is a continuation of PCT application filed April 3, 2020, with serial number PCT / US20 / 26728, entitled "Improved Deformable Stroller Component", which is a continuation of U.S. patent application filed April 3, 2019, with serial number 16 / 373800, entitled "Deformable Stroller Component", the disclosure of which is incorporated herein by reference at least. Technical Field

[0003] This invention belongs to the field of strollers, and more specifically relates to a deformable stroller assembly with a pop-up privacy panel. Background Technology

[0004] A typical stroller includes a seat and backrest joined together, allowing the components to hinge so that the seat can remain level and the backrest can be adjusted to the desired angle, reducing the distance from the seat. The seat and backrest are supported by a lightweight frame comprising at least four legs that culminate in the stroller wheels. Frame components may be provided as push rods to allow the user to push the stroller. Strollers often include features for user convenience, such as a cup holder, fabric bag, wheel brakes, a temporary tray, and a canopy. Some strollers have a double seat.

[0005] The inventors know of a stroller, as described in the cross-references in the related literature section above, which can be converted into a diaper changing table via an angled seat and backrest assembly, the backrest being manually adjustable to a relatively horizontal position so that the baby can lie down safely for diaper changing. In addition to this capability, the stroller also includes opposing privacy panels, each located on each side of the stroller.

[0006] Privacy panels are vertically oriented on both sides of the stroller and are slidably attached to the stroller's vertical frame elements. These privacy panels can be raised vertically above the level of the stroller seat to form a highly opaque barrier on each side of the seat. These panels can rattle in the wind, may be difficult to lift and lock, and may encroach on space on each side of the stroller where pockets and other features such as diaper and wipes storage bags could be provided. The known deformable strollers, with their boxy vertical frame design, wheelbase length, width, and seat height, may be unsafe in supporting an infant's weight. The stroller may tip over if the user rolls up or down a moderate incline. Similarly, parking facing or perpendicular to the incline may cause the stroller to tip over.

[0007] One issue with privacy panels is that the frame assembly comprises multiple sections that must be individually manipulated by the stroller operator to raise and lower them. Furthermore, the stroller operator must ensure that the panels are fully folded on both sides before folding the stroller frame from a relatively horizontal position to a fully folded position for storage.

[0008] Therefore, there is clearly a need for a stroller that can transform into a diaper changing table to reduce or eliminate the above problems. Summary of the Invention

[0009] According to an embodiment of the present invention, an articulated stroller platform is provided, comprising: a material-encapsulated seat portion articulatedly connected to a material-encapsulated backrest portion, the backrest portion being mechanically adjustable to fold downwards over the seat portion and mechanically adjustable to unfold from the folded position, the backrest portion being additionally mechanically adjustable from a sharper angle to the seat portion to form a horizontal relationship with the seat portion for use as a diaper changing table; a pair of material-sealed privacy panels connected to opposing material edges of the seat portion via material seams, providing privacy... The privacy panel is positioned vertically when the stroller platform is unfolded and prone against the top surface of the seat portion when the stroller platform is folded; and a pair of elongated pull straps, each strap anchored to the privacy panel on each side of the stroller platform, each strap passing through a pair of elongated slots provided in the seat portion and returning upward to connect at the respective free end to or onto a corresponding arm base tube of a pair of arm base tubes connected to the stroller frame, the base tubes being configured to position an arcuate tubular arm above and in front of the seat portion of the stroller platform.

[0010] According to one embodiment, each pull strap is attached by sewing to the outward-facing surface of the corresponding privacy panel. In another embodiment, each pull strap is attached by sewing to the inward-facing surface of the corresponding privacy panel and passes through the panel to the outer surface. In one embodiment, each pull strap is arranged downward from the outside of the corresponding privacy panel into a corresponding elongated slot in the seat portion, passes through the outer edge of the seat portion, and connects upward to the corresponding arm base tube or thereon. In another embodiment, each pull strap is arranged downward from the outside of the corresponding privacy panel through the outer edge of the seat portion, passes inward and upward through the corresponding elongated slot in the seat portion, and connects upward to the corresponding arm base tube or thereon.

[0011] In one embodiment, the corresponding free end of the pull strap is a loop, which is placed on the end of the arm base tube before the arm is attached to the stroller platform. In another embodiment, the corresponding free end of the pull strap includes a connection interface that connects to the arm base tube. In this embodiment, the connection interface is a snap-fit ​​interface, a hook interface, or another hardware implementation.

[0012] In one embodiment, when the stroller platform is folded, the privacy panel is pushed inward by contacting the top rear corner of the privacy panel via the interface side of the backrest portion. In another embodiment, the privacy panel has a counterweight on its inner surface to facilitate a natural inward downward descent when the stroller platform is folded. Attached Figure Description

[0046] Now refer to the attached diagram, especially Figures 1 to 9 This will describe a new stroller device embodying the principles and concepts of embodiments of this disclosure and generally indicated by reference numeral 10 in the accompanying drawings. Figures 1 to 9As best shown, the convertible stroller assembly 10 typically includes a stroller 12 having a seat 14 and a backrest 16 pivotally connected to the seat 14. The backrest 16 is in an upright position so that the seat 14 and backrest 16 allow an infant to sit on it. In a tilted position, each of the seat 14 and backrest 16 forms a diaper changing table 18. In this way, the seat 14 and backrest 16 allow an infant to lie on it for diaper changes. The stroller 12 includes multiple wheels, support legs 34, and other structural components common to strollers.

[0047] The seat 14 has a top surface 20, a bottom surface 22, a first lateral edge 24, and a second lateral edge 26. The backrest 16 has a front surface 28, a rear surface 29, a first lateral edge 30, and a second lateral edge 32. A pair of support legs 34 are each pivotally connected to the backrest 16, and each support leg 34 is positioned in an extended position when the backrest 16 is positioned in an inclined position to support the backrest 16. In this way, the backrest 16 can support the weight of an infant. Each support leg 34 has a first end 36 and a second end 38, and the first end 36 of each support leg 34 is pivotally connected to the rear surface 29 of the backrest 16. When the support legs 34 are in the extended position, each support leg 34 extends downward from the backrest 16, and the second end 38 of each support leg 34 abuts against the ground or other supporting surface. Furthermore, when the support legs 34 are positioned in a stored position, each support leg 34 abuts against the backrest 16.

[0048] A seat cushion 40 is positioned on the seat 14 and is made of a resilient, compressible material. A strap 42 extends on the seat cushion 40 and can engage with itself to form a closed loop for holding the baby on the seat cushion 20. In this way, the strap 42 prevents the baby from rolling off the changing table 18. A backrest cushion 44 is located on the backrest 16 and is made of a resilient, compressible material. A first pin 46 and a second pin 48 are respectively connected to and extend from one of the first lateral edges 24 and the second lateral edge 26 of the backrest 16.

[0049] A pair of discs 50 are provided, each disc 50 having a first surface 52, a second surface 54, and a peripheral edge 56. Furthermore, each disc 50 has a plurality of holes 58 extending through the first surface 52 and the second surface 52. The holes 58 in the respective discs 50 are spaced apart from each other and distributed along the peripheral edge 56 of the respective disc 50. The pair of discs 50 includes a first disc 60 and a second disc 62. The first disc 60 is coupled to a first lateral edge 24 of the seat portion 14, and the second disc 62 is coupled to a second lateral edge 26 of the seat portion 14. Each of the first pin 46 and the second pin 48 engages with a selected one of the holes 58 in the respective disc of the first disc 60 and the second disc 62 to hold the backrest 16 relative to the seat portion 14 at a selected angle.

[0050] A pair of privacy panels 64 are slidably attached to the seat 14. Each privacy panel 64 is positioned in an unfolded position and extends upward from the seat 14. Each privacy panel 64 conceals the baby during diaper changes. Furthermore, each privacy panel 64 is positioned in a storage position, and each privacy panel 64 includes a first lateral rail 66 and a second lateral rail 68. Each of the first lateral rail 66 and the second lateral rail 68 may have a plurality of engagement points 70 thereon, distributed along the entire length of the first lateral rail 66 and the second lateral rail 68. Each privacy panel 64 may have a cup holder 71 attached thereto for holding a beverage cup.

[0051] Multiple receivers 72 are respectively coupled to stroller 12, each receiver 72 slidably engaging a corresponding privacy panel 64 to slidably hold the privacy panel 64 on stroller 12. Each receiver 72 has a front wall 74 spaced apart from a rear wall 76 to define a groove 78 extending between the front wall 74 and the rear wall 76. The rear wall 76 of each receiver 72 is coupled to stroller 12 such that an axis extending through the groove 78 is vertically oriented. The groove 78 in each receiver 72 slidably receives a corresponding one of a first lateral rail 66 or a second lateral rail 68 of the corresponding privacy panel 64, such that the privacy panel 64 can be raised and lowered within the receiver 72. Multiple screws 80 each extend through the front wall 74 of a corresponding one of the receivers 72. When the screws 80 are tightened to hold the privacy panel 64 in a selected position, each screw 80 engages a corresponding first lateral rail 66 or second lateral rail 68 of the corresponding privacy panel 64. In addition, each screw 80 can engage one of the engagement points 70 in the corresponding first lateral rail 66 or second lateral rail 68.

[0052] A canopy 82 is provided, which is foldably attached to the backrest 16. When the baby is seated in the stroller 12, the canopy 80 is positioned in the unfolded position to shield the baby. Furthermore, the canopy 81 is positioned in the storage position before the backrest 16 is positioned in the reclining position. A tray 84 is attached to the rear edge 86 of the backrest 16, and the tray 84 is oriented at an angle to the rear surface 29 of the backrest 16. Furthermore, when the backrest 16 is positioned in the upright position, the tray 84 is oriented to be on a horizontal plane. Thus, the tray 84 can be gripped to push the stroller 12. The tray 84 may include a cup holder and a storage well. A storage box 88 for wet wipes is attached to the bottom surface 22 of the seat 14 for storing wet wipes used for diaper changes.

[0053] In use, the backrest 16 is positioned in an upright position for transporting the baby using the stroller 12 in a conventional manner. When the baby needs a diaper change, each support leg 34 is positioned in an extended position, and the backrest 16 is positioned in a tilted position. In this way, a diaper changing table 18 is formed. Each privacy panel 64 is positioned at a selected height to conceal the baby during diaper changes. When the diaper has been changed and the baby in the stroller 12 is to be transported again, the backrest 16 is positioned in an upright position.

[0054] Figure 10 This is a right-side view of a stroller frame 100 according to an embodiment of the present invention. The frame 100 includes a rear support leg tube 122a and a front support leg tube 122b. The front support leg tube 122b is located outside the rear support leg tube 122a relative to the arrangement of tubes on the transverse members of the frame at the center view where the tubes are mounted. However, in one embodiment, the opposite is possible without departing from the spirit and scope of the invention.

[0055] The rear outrigger tube 122a and the front outrigger tube 122b can be made of steel or aluminum tubing, which is formed into an arcuate profile during a forming and bending process. The arcuate design of the outrigger tubes provides a larger shock-absorbing frame relative to vertical impact forces. The front outrigger tube 122b includes a pair of front wheels 124 (one of which is visible). The rear outrigger tube 122a includes a pair of rear wheels 123 (one of which is visible).

[0056] The diameter of the front wheel 124 may be smaller than that of the rear wheel 123. The front wheel 124 is free to rotate, while the rear wheel 123 may be mounted on a fixed axle that cannot rotate relative to the stroller's lines. The stroller frame 100 includes additional frame support transverse members (not visible in this view) near the lower ends of the front and rear support tubes.

[0057] The stroller frame 100 includes a molded backrest 90 and a stroller control handle tube 121. The molded seat 90 and stroller control handle tube 121 are both located on the transverse members of the main frame. Figure 11 At position 127), both the front and rear support leg tubes rest on the transverse member of the main frame. Although the positions of the front and rear support leg tubes 122b and 122a are fixed relative to each other, the positions of the molded backrest 90 and the stroller control handle tube 121 can be pivoted about the transverse member of the main frame in a controlled manner. The seat 132 can also engage with the aforementioned transverse member. The seat 132 may have a footrest 89 rotatably attached to the distal end of the seat via a hinge 133.

[0058] The wheelbase dimension D1 reflects the length of the stroller 100 from the centerline of the wheel to the centerline (from back to front). In a preferred embodiment, D1 is approximately 45-75 centimeters (cm), and in this embodiment, it is 66.2 cm. The seat height D2 reflects the height of the bottom 103 of the molded plastic seat of the stroller from the ground. D2 is approximately 50-65 cm, and in this embodiment, it is 58 cm from the ground to the top of the seat 132. This orientation of the wheelbase dimension and seat height is necessary to provide stability during backrest positioning and to provide the seat height required for comfort when the user changes passengers.

[0059] It should be noted that the centerline of the main transverse member at the apex of the curved outrigger tube profile is closer to the rear wheel 123 than to the front wheel 124. For example, the distance from the rear wheel 123 to the centerline of the main transverse member is in the range of 28-35 cm, and in this embodiment, it is approximately 30.2 cm, while the distance from the front wheel 124 to the centerline of the main transverse member is in the range of approximately 32-38 cm. This dimension is designed to shift the center of gravity rearward toward the rear of the stroller, thereby providing greater stability during use and preventing the stroller from tipping over.

[0060] Figure 11 yes Figure 10 A front view of a stroller frame 100. In this view, the main lateral member 127 (upper lateral member) and the lower supporting lateral member 128 (lower lateral member) are visible, extending between the front wheels 124. The wheels 124 are visible in this view, while the rear wheels 123 are not depicted. This front view assumes that the width dimension D3 of the wheelbase, measured from the centerline to the centerline of the wheels 124, is substantially the same as the width dimension of the rear wheels 123. However, this should not be construed as limiting, as the rear wheelbase width dimension can be significantly wider than the front wheelbase width dimension without departing from the spirit and scope of the invention, and this is preferred in most embodiments. D3 can be in the range of 35-56 cm, and in this embodiment, it spans approximately 50 cm from the centerline to the centerline across the front wheels 124.

The slots reserved for securing the child to the shoulder straps on the changing table are slots 100 (upper slot), 101 (middle slot), and 102 (lower shoulder strap slot). The slots 100, 101, and 102 are strategically positioned above the seat surface of the molded backrest 90.

[0075] In this view, a shoulder strap 99 is provided, one end of which is anchored aligned with and passes through a lower shoulder strap groove 102. The shoulder strap 99 returns through an upper groove 101 (the next highest group) and then through an upper groove 100 (the next highest group in group 101). The shoulder strap 99 prevents the baby from rolling over or sitting up during diaper changes.

[0076] Figure 17 yes Figure 16 An enlarged side view of the shoulder strap configuration of the shoulder strap 99 is shown inside the support. In this view, the shoulder strap 99 is anchored to the lower shoulder strap groove 102 from behind the padded material shown in the section line. The strap 99 passes through the lower shoulder strap groove 102, returns through the intermediate groove 101, and then returns through the upper groove 100 of the backrest 90.

[0077] Pop-up privacy panel and operation

[0078] The object of this invention is to provide a design for a pair of privacy panels (integrated into the stroller material) located on opposite sides of the stroller seat, which provide greater and more privacy for the user and the baby during diaper changes. Another object of this invention is to provide a device for popping out the privacy panels when needed and folding them when not needed, without requiring additional tasks beyond unfolding and folding the stroller.

[0079] Figure 18 This is a front view of a deformable stroller 1800 with a pop-up privacy panel according to an embodiment of the present invention. The structure and materials of the stroller 1800 are similar to those described above. Figure 10 The stroller described above is similar to the 100 model, except for the pair of privacy panels 1803 (one of which is visible), which replace the one described above. Figure 13A The framework components introduced in the text are 200.

[0080] Privacy panel 1803 is a solid panel encapsulated in a material such as a padded product and shaped into a rounded rectangle or arc, having a static and non-adjustable total storage length and total storage height. Privacy panel 1803 may be formed from a rigid material (such as plastic or metal sheet) with sufficient thickness to resist bending, warping, or twisting. The panel is encased or surrounded by a durable material, which may include rigid padding material on both sides of the panel components. Privacy panel 1803 may be padded, in which the panel is covered by padding and material.

[0081] The privacy panel 1803 is typically positioned on the opposite side of the bottom of the stroller seat 1804 and sewn onto the bottom cover material of the seat. When the stroller 1800 is folded to the closed position for storage, the privacy panel can be folded flat relative to the bottom of the seat 1803. The privacy panel is folded flat against the bottom of the seat when the stroller backrest 1801 is folded down on its top.

[0082] In a preferred embodiment, a pull strap system automatically pulls the privacy panel upward from a folded position to a generally vertical position, with the outer surface of the panel resting against a stroller arm, referred to herein as arm 1806. Arm 1806 may be a flexible tubular member removable from stroller 1800 and may be attached to a pair of arm base tubes 1807, which are connected on both sides to the stroller frame (not shown on the back side) near the seat bottom 1804. A flexible pull strap 2101 with length, width, and material thickness is provided. The pull strap 2101 may be attached to the outer surface of the privacy panel 1803 below the vertical center and facing rearward. In one embodiment, one end of the pull strap is sewn into the panel material, providing an anchor point 2201 for pulling the privacy panel upward to a vertical use position.

[0083] A stroller platform, including a backrest 1801 connected to the seat bottom 1804, is fitted to a stroller frame 100, wherein the backrest 1801 can be adjusted from vertical to horizontal to form a changing table. The stroller 1800 can be folded for storage and unfolded for use. A privacy panel 1803 folds down when the stroller is folded for storage and pops out when the user unfolds the stroller for use. In one embodiment, the stroller platform includes a footrest portion that... Figure 12A The footrest is introduced and described as 89. Practicing this invention does not require a footrest.

[0084] In a preferred embodiment, the arm 1806 extends to a length sufficient to clear the front edge of the privacy panel 1803 to prevent accidental contact between the panel and the arm structure. In one embodiment, the arm 1806 may be angled relative to a generally horizontal position of the seat base 1804. It is understood that the stroller platform, including the backrest 1801 and the seat base 1802, may be covered with durable fabric material or padded. Similarly, the presence of materials designed for storing items is assumed in this embodiment. The privacy panel 1803 remains vertical when the backrest 1801 is angled downwards to form a near-horizontal angle with the bottom seat 1804 to create a changing table. The backrest 1801 may include side edges 1809 extending from the backrest 1801 on both sides and, in one embodiment, across the top of the backrest.

[0085] The seat base 1804 includes a pair of elongated slots 2202 provided by material that breaks through the seat base. Detail 1811 depicts a slot extending generally longitudinally with the stroller platform seat base in a dashed boundary near the edge of the seat base. These slots are spaced apart such that one slot aligns with each side of the seat base. A pull strap 2101 can be guided from the anchor point 2102 into the slot 2202, then towards the edge of the seat base 1804, extending upward around the edge to and connecting to, or onto, the proximal arm base tube 1807. This configuration can be repeated on both sides of the stroller 1800.

[0086] In one embodiment, the pull strap 2101 includes a loop sewn to its free end, the loop having a sufficiently large diameter to loosely fit the outer diameter of the arm base tube 1807. In this configuration, the privacy panel 1803 pops out when the user unfolds the stroller, thus unfolding the stroller platform for use. When the stroller is folded back for storage, the panel 1803 folds down and rests against the top surface of the seat base 1804. In one embodiment, a pair of top seams 1810 are provided in the material sidewalls 1809 of the backrest 1801, starting from a point at the top of the sidewall in the lower region of the backrest, the seams sloping downwards to the seam edges of the base 1804 and the backrest 1801. This forms a fold line so that when the stroller 1800 is folded, the lower edge of the sidewall 1809 contacts the upper rear corner of the privacy panel 1803, facilitating inward pushing of the panel. These angled areas at the bottom of sidewall 1809 can be moderately reinforced by inserting appropriately cut pieces of plastic sheet material (invisible) between the padding material up to the top seam 1810. Further details regarding the pull strap system utilizing pull strap 2101 are provided below.

[0087] Figure 19 yes Figure 18 A partial front view of a stroller 1800, showing a pop-up privacy panel in an upright position. In this view, as the stroller unfolds from its storage position, the privacy panel 1803 is vertically positioned relative to the seat base 1804. When the stroller is folded back to its storage position, the panel 1803 can be folded down and laid flat on the seat base 1804 in the direction of the arrow. In this embodiment, each privacy panel has a top seam 1805. Furthermore, in this embodiment, a pair of double-stitched seams 1809 are provided to secure the privacy panel downwards to the opposing material edges of the padded seat base 1804. A double seam may also be provided between the backrest 1801 and the seat base 1802.

[0088] In this embodiment, the privacy panel 1803 is stitched at its bottom to the edge material of the seat base 1804 using a seam seam 1809. The seam between the privacy panel and the seat base is reinforced, and the width of the seat base is slightly reduced to allow sufficient clearance between the hard edge of the seat and the panel edge of the privacy panel to easily and without interference fold downwards to a folded position lying flat on the seat base 1804. The privacy panel 1803 extends to the footrest portion 1802 of the stroller 1800, which is substantially attached to the front edge of the seat base 1804. The footrest 802 may be similar to the one described above. Figure 12A 89. Footrest.

[0089] In this example, the top of the privacy panel 1803 is slightly curved along the length of the panel. In another embodiment, without departing from the spirit and scope of the invention, the panel may be a rectangle with fewer rounded corners, and the vertical height of the rectangular panel may be the same as that of the curved panel.

[0090] Figure 20 yes Figure 18 A partial perspective view of stroller 1800 depicting the downward-folding privacy panel. In this view, the privacy panel 1803 is depicted folded down and lying flat on the base 1804; the arm has been removed for clarity. For clarity, material and seams have been removed, and the hard gaps between solid parts are illustrated to aid in unobstructed operation of the panel. (See reference above.) Figure 18 The pull strap system is used to pull the panel 1803 to an upright position when the stroller 1800 is unfolded to an upright position for use. The pull strap system includes two pull straps 2101 of specific lengths, one pull strap for each side of the bottom 1804 of the stroller seat. The pull straps 2102 may be made of heavy webbing material with a total length, width and material thickness.

[0091] The rear edge of the privacy panel 1803 is generally parallel to the fold line between the backrest 1801 and the seat base 1804. In this embodiment, one end of the pull strap 2101 is sewn to the covering material on the outside of the panel 1803, and this configuration is repeated on the other side of the stroller. In one embodiment, the pull strap 2101 is arranged downward from the outer surface of the panel 1803 and enters a groove 2202 placed through the seat base 1804, then goes below the seat base 1804 and around to the outside of the seat base 1804, and is arranged upward to secure to the tubular base portion 1807 of the arm (the arm has been removed for clarity). A pair of grooves 2202 are provided on each side of the stroller seat base 1804.

[0092] In this example, the free end of the pull strap 2101 forms a loop by sewing, snapping, or nailing the end of the strap to itself. The loop end has a sufficient inner diameter to loosely fit onto the outer diameter of the tubular base portion 1807 of the boom. In one embodiment, without departing from the spirit and scope of the invention, the pull strap 2101 can be attached to the tubular boom base 1807 by other methods, such as via a snap-fit ​​interface, hook interface, or other hardware implementation.

[0093] In this embodiment, the angle of the arm changes during the folding and unfolding of the stroller platform. When folded, the arm becomes sharper relative to the horizontal plane of the seat bottom, while when unfolded, the arm becomes less sharp relative to the horizontal plane of the seat bottom. This ensures that sufficient strap material remains slack when folded, allowing the privacy panel 1803b to... Figure 20 The stroller 1800 is folded flat as shown. When the stroller 1800 is unfolded for use, slack in the strap 2101 is absorbed by raising the arm angle, causing the panel 1803b to stand upright against the inside of the arm. In this way, the privacy panel 1803 can automatically pop out and fold down automatically without requiring manual placement or adjustment by the user. After the stroller is in the use position, the backrest 1801 can be further adjusted to change the backrest angle to a horizontal position for use as a changing table.

[0094] Figure 21A It is based on detailed drawing 1811. Figure 18 A partial enlarged view of the stroller 1800 depicts the first position of the pull strap relative to the bottom of the seat of the stroller in the open position with the panel facing upwards. In this view, the pull strap 2101 is secured to the outer surface of the privacy panel 1803 (not visible) at anchor point 2201 (not visible), and extends downwards through a groove 2202 (not visible) in the bottom of the seat 1804, then around the proximal side of the bottom of the seat, and then flips upwards (loops) to secure it to the arm base tube 1807 (not visible) or thereon.

[0095] The stroller handle 1808 obstructs the view of the arm base tube 1807, however, it is visible in the next view. For reference purposes, a dashed line is provided on the pull strap 2101, depicting the advance of the pull strap through the slot 2202 relative to the alternative folded position of the stroller. The dashed line indicates a marker indicating the position of the strap relative to the unfolded state of the stroller, where the privacy panel remains vertical.

[0096] Figure 21B It is based on details 1811 Figure 18A partial enlarged view of stroller 1800 depicts the forward travel of the pull strap through the slot in the stroller's folded state. With the panel facing down in the folded position, the position mark shows the forward travel distance A relative to the bottom of the stroller's seat. In this view, the arm base 1807 is visible and secures the free end of the pull strap 2101. In the folded position, the privacy panel lies flat on the bottom of the seat 1804. Dashed reference lines have been drawn from... Figure 21A The unfolded position shown has advanced a distance A (middle of the drawing). The handle 1808 is presented at a different angle, exposing the arm base tube 1807. Distance A represents the amount of slack required in the strap loop so that the privacy panel can lie completely flat on the seat bottom 1804 when the stroller is folded down for storage.

[0097] Figure 22A yes Figure 18 A partial enlarged view of detail 1811 depicts the attachment end of the pull strap to the privacy panel before it is positioned into a slot at the bottom of the seat. In this view, one end of the pull strap 2101 is sewn to the privacy panel 1803 at an anchor point 2201. The anchor point 2202 is positioned to the outer surface of the panel 1803 and faces below the horizontal center of the panel, towards the rear of the panel. The pull strap 2201 is not yet inserted into the slot 2202. The slot 2202 is configured to pass through the bottom of the seat substantially parallel to the near edges on both sides. The slot 2202 has a length and width adapted to the width and material thickness of the pull strap 2101 to provide a smooth or unrestrained sliding fit through the slot 2202. This configuration can be repeated on the other side of the stroller. The slot 2202 may have rounded smooth edges and polished inner walls to help reduce friction with the bidirectional and repetitively advancing pull strap 2101 when the stroller is in operation.

[0098] Figure 22B yes Figure 18 A close-up view of the stroller, depicting... Figure 22A The pull strap passes through Figure 22A The groove. In this view, the pull strap 2201 is arranged on the boom base tube 1807 and inserted directly into the groove from top to bottom, and then the free end is arranged around the bottom of the seat and upward to secure the pull strap to the base tube 1808.

[0099] Figure 23 yes Figure 18 A partial top perspective view of the bottom of the stroller seat 1804, with material removed, depicting elongated grooves running through the bottom of the seat for the pull strap to pass through. The grooves 2202 are substantially parallel to the corresponding outer edges of the bottom of the seat 1804. Each groove is located near the rear edge of the bottom of the seat 1802 and near the inner edge of the base tube 1807 of the arm (removed for clarity).

[0100] Figure 24 yes Figure 23A partial top perspective view of the bottom of the seat, with material removed, depicts the pull strap passing through a groove in the bottom of the seat and around the outer perimeter of the seat. In one embodiment, the arrangement of the pull strap 2101 differs slightly from that described further above. Furthermore, the material of the pull strap 2101 sewn to the outer surface of the privacy panel 1803 at anchor point 2201 is also disclosed. Figure 22A The free end of the pull strap passes directly downwards from the top through the slot into slot 2202, then around the lower side of the seat bottom 1804 to the outer edge, and then is fixed upwards to or attached to the arm base tube 1807.

[0101] Alternatively, the free end of the pull strap 2101, anchored at anchor point 2201 to the material covering the privacy panel 1803, can pass downwards through the outer edge of the seat bottom 1804, then upwards through the groove 2202, and further upwards to the arm base tubes 1807 on either side of the configuration. In this embodiment, a loop is fixed to the free end of the pull strap to loop around the arm base tube 1807. When the stroller is unfolded from the folded position, the privacy panel is pulled to the upright position; when the stroller is folded for storage, the privacy panel falls inwards to fold. This alternative arrangement provides the same operational characteristics. The alternative arrangement of the pull strap will be described in more detail below.

[0102] Figure 25A yes Figure 18 A partial perspective view of the stroller 1800 depicts a pull strap sewn to the outside of the privacy panel and through a groove according to an alternative arrangement embodiment. In this alternative arrangement embodiment, one end of the pull strap 2101 is anchored to the outside of the privacy panel 1803 at anchor point 2201. The pull strap 2201 extends downward from anchor point 2202 to the outside of the seat bottom 1804, then wraps around and upward through the pull strap groove 2202. A loop at the free end of the pull strap 2102 is ready to be placed on the arm base tube 1807. Once the loop is secured to the base tubes on both sides of the stroller, the arm (1808) can be positioned.

[0103] Figure 25B yes Figure 18 A partial perspective view of the stroller 1800 depicts a pull strap 2101 arranged downwards from anchor point 2201 into a groove 2202 according to a first arrangement embodiment. In this view, the pull strap 2201, anchored to the privacy panel 1803 via anchor point 2102, is first guided directly from the top into the groove 2202, then wraps around from below to the outside of the seat bottom 1804, up to the arm base tube 1807. A loop at the free end is secured to the arm base tube 1807 before the arm is attached. This arrangement can be repeated on both sides of the stroller.

[0104] Figure 26 yes Figure 18A partial perspective view of the stroller 1800, detail 1811 depicts a pull strap anchored to a privacy panel and passing through the bottom of the seat, with a loop at its free end secured to the base of the arm. This view depicts the above... Figure 25B The first arrangement embodiment described herein includes a loop of pull strap 2101 fixed to the arm base 1807. The pull strap 2101 may be cut to a specific length (additionally for the loop) to ensure that an appropriate length is provided so that when the stroller is folded, the side panels can lie flat on the bottom of the seat and can be pulled upward to a vertical position with the panels against the inside of the arm.

[0105] In a variation of the above embodiment, the pull strap 2101 may not be anchored to the outer surface of the privacy panel 1803 at anchor point 2201. Instead, the pull strap may pass through the outer surface of the privacy panel to the inner surface and be anchored thereto. According to this variation, a top seam (1809) may be provided on the material side at the lower end of the backrest (1801). Figure 18 This creates a pair of slanted fold lines that extend inwards and downwards from the outside, angled to the seam connecting the backrest and the bottom of the seat. A plastic sheet can be added to the inner padding beneath the material in this area (both sides of the backrest) to reinforce the material. The plastic sheet remains hidden beneath the material.

[0106] The aforementioned modification allows the underside of the outer material of the backrest to contact the privacy panel at the outer rear corner, so as to push the privacy panel inward and downward toward the bottom of the seat 1804 when the stroller is folded. This ensures that the panel is pushed downward with a gentle force, thereby reducing the task of the user physically pushing the panel inward or having to check the panel before folding the stroller. In another embodiment, each privacy panel 1803 may be counterweighted on its inner surface, preferably along the top inner surface, so that it may fall inward naturally if it is not held in an upright position by the tension of the pull strap 2101.

[0107] Regarding the foregoing description, it should be recognized that the optimal dimensional relationships of the parts in the embodiments achievable by this disclosure, including variations in size, material, shape, form, function and operation, assembly and use, will be apparent to those skilled in the art, and all equivalent relationships with those shown in the drawings and described in the specification are intended to be included in the embodiments of this disclosure.

[0108] Therefore, the foregoing is considered merely an explanation of the principles of this disclosure. Furthermore, since numerous modifications and alterations are readily possible for those skilled in the art, it is not intended to limit this disclosure to the exact structures and operations shown and described; thus, all appropriate modifications and equivalents may be employed, all within the scope of this disclosure. In this patent document, the word "comprising" is used in its non-limiting sense to mean including the items following the word, but does not exclude items not specifically mentioned. The indefinite article "a" referring to an element does not exclude the possibility of more than one element, unless the context explicitly requires only one element.
