DESCRIPTION

Stroller system

Technical field

This disclosure refers to strollers.

Background

A stroller is generally a chair-like cart, often foldable, with four wheels to transport an infant or child. An infant or child generally sits or reclines in a stroller seat when a user (eg, a parent) propels the stroller in a desired direction. Strollers typically include a single seat to accommodate a single passenger to be transported. However, some strollers include two seats, either side-by-side or one in front of the other, and are typically used for twins or two children who are still of the age that need the stroller. However, when a second seat is no longer needed or desired, the stroller may no longer be functional for its new purpose of carrying a single child. In contrast, a single seat stroller may no longer be desired when there is a need to transport two children at the same time.

Resume

The present disclosure provides a stroller system that includes a seating system removably attached to a stroller chassis, thereby offering additional seating capacity of a stroller.

In one aspect, the stroller system includes a stroller frame and a seating system. The stroller frame includes first and second frame supports disposed spaced apart, an optional at least third frame support that secures the first frame support to the second frame support, and wheels rotatably attached to one or more over the rack brackets. The seat system is removably attached to the frame of the stroller and includes a seat support having first and second end portions, and first and second end connectors disposed on corresponding first and second end portions of the seat. seat support. Each end connector includes a connector body having first and second end portions, each end portion defining a recess configured to receive one of the frame supports. The recesses arranged substantially opposite to engage the support received in substantially opposite directions.

In some implementations, the stroller frame includes fourth and fifth frame supports, each having first and second end portions. The first end portions of the fourth and fifth supports are rotatably coupled to the first and second frame supports, respectively. The fourth and fifth supports are movable between a stowed position substantially parallel to the first and second supports and a position deployed at an angle with respect to the first and second supports. One of the wheels is rotatably attached to the second end portion of each of the fourth and fifth frame supports. In some examples, the first and second frame supports are arranged on a front portion of the stroller frame for receiving the seating system in a frontal position on the stroller frame.

In another aspect, a system for a stroller includes a seat support having first and second end portions, and first and second end connectors disposed on corresponding first and second end portions of the seat support.

Detailed description

With reference to Figures 1-3, a stroller system 10 includes a stroller frame 100 and a seat system 200 removably attached to the stroller frame 100 to provide additional removable seating capability to the frame. 100 from the stroller. The seat system 200 can be adjustable or otherwise adaptable to be accommodated by various types of strollers. The example stroller frame 100 shown includes first and second supports 110, 120, each having a first end 112, 122 and a second end 114, 124. A third and fourth supports 130, 140, each It has a first end 132, 142 and a second end 134, 144, with the first ends 132, 142 rotatably attached to respective first and second supports 110, 120. The third and fourth supports 130, 140 pivot between a deployed position (as shown) to provide a fourth contact point configuration and a retracted position, in which the third and fourth supports 130, 140 are adjacent, close to, or substantially parallel to the first and second supports 110, 120. The first and second supports 110, 120 are spaced substantially parallel or angled to each other, and a fifth support 150 is attached to the second ends 114, 124 of the first and second supports 110, 120. An optional sixth support 160 may be attached to the first and second supports 110, 120 to provide additional rigidity for the frame 100 of the stroller as a whole. Wheels 170 are also attached to second ends 134, 144 of third and fourth supports 130, 140. A main seat (not shown), such as a baby chair or a child chair, can be removably attached to the first and second supports 110, 120. In the example shown, the first and second seat receivers 116, 126 are disposed on the respective first and second supports 110, 120 and configured to receive and hold mating members of the main seat. In some examples, the main seat is permanently attached to the stroller frame 100.

Referring to Figures 4-8, the seat system 200 includes a seat support 210 having first and second end portions 212, 214. The example seat bracket 210 shown defines a substantially U-shape from a top view; however, other shapes and configurations are possible, such as an M shape, etc. A seat 220 (shown in FIG. 3) is attached to seat support 210 and configured to receive a child or infant. Seat 220 may be made of fabric, plastic, or other suitable material. In the example shown, the seat 220 comprises a woven nylon fabric attached to the seat support 210 by fasteners (eg, through stitching, adhesive, snaps, and hook and loop fasteners, etc.). The first and second end connectors 302, 304 are attached to the corresponding first and second end portions 212, 214. In some implementations, the first and second end connectors 302, 304 are removably attached (eg, through a snap fit, threaded connection, locking bolt, clamp, etc.) to the corresponding first and second portions 212, 214 extreme. In some examples, the first and second end connectors 302, 304 are mirror images of each other. Each of the connectors 302, 304

The ends include a connector body 310 having first and second end portions 312, 314. Each of the end portions 312, 314 defines a respective recess 316, 318 configured to receive a frame support (eg, the first and second supports 110, 120) of the stroller frame 100. End portions 312, 314 are disposed substantially opposite each other to provide counter engagement of a received stroller frame support.

The seat system 200 is attached to two stroller frame supports. Referring again to Figures 1-3, the seat system 200 is received by the exemplary stroller frame 100 by positioning the first and second end connectors 302, 304 above the first and second frame supports 110, 120. separated to receive the seating system 200. The first end portions 312 of the first and second end connectors 302, 304 are positioned to receive the first and second frame supports 110, 120 in their respective recesses 316 (eg, an opening in a substantially tubular structure). The seat system 200 is rotated causing the connectors 302, 304 to pivot with respect to their first and second end portions 312 toward the respective first and second frame supports 110, 120 until the second end portions 314 of the first and second connectors 302 , 304 ends engage and receive the first and second frame supports 110 and 120 in respective recesses 318 of the second end portions 314 of the first and second end connectors 302, 304, thereby attaching the seat system 200 to the first and second frame supports 110, 120. The seat support 210 is cantilevered from the first and second frame supports 110, 120. A child received in the seat 220 causes the seat support 210 to attempt to rotate down relative to the second end portions 314 of the first and second end connectors 302, 304 until the first end portions 312 of the first and second connectors 302, 304 The ends engage the frame supports 110, 120 to prevent twisting, thereby cinching, locking, or otherwise immobilizing the seat support 210 in place.

With reference to FIG. 3, in some implementations, the seat system 200 is specifically adapted for attachment to a front portion 101 of the frame 100 of the received stroller. Although, in other implementations, the seat system 200 may be attached to a rear portion 103 of the stroller frame 100 as well or instead. In the example shown, the first and second frame supports 110, 120 are arranged at the front position 101 of the stroller frame 100 for receiving the seating system in a front relative position on the stroller frame 100. The rear-facing seat system 200 cantilevered from the rear portion 101 of the stroller frame 100 allows the transportation of a child in a convenient position within the supervision of a user (eg, a parent or caregiver). . In addition, the front side attachment of the seat system 200 to the front portion 101 of the stroller frame 100 provides ergonomic ease of use, allowing attachment to an upward facing portion of the stroller frame 100, for example. example. In the example of rear side attachment to the rear portion 103 of the stroller frame 100, the seat support 210 as well as the first and second end connectors 302, 304 are configured for attachment to the third and fourth supports 130, 140 in its deployed position. The method of attachment is the same or substantially similar to that of attachment to the front portion 101 of the stroller frame 100, thus providing multiple seat configurations of the stroller system 10. The seat system 200 may be arranged facing forward with a rear-side attachment to the stroller frame 100.

In the examples shown, recesses 316, 318 are substantially semicircular or C-shaped to receive a tubular stroller frame support therein and partially surround the tubular stroller frame support in an end view. In some examples, the recesses 316, 318 are substantially semi-circular or U-shaped. Recesses 316, 318 may define other shapes as well, such as elliptical and polygonal shapes, to receive similar or dissimilar cross-sectional shaped frame supports. The recesses 316, 318 are also disposed substantially opposite each other to engage the received stroller frame support in substantially opposite directions to prevent rotation of the seat system 200 along one direction. The recesses 316, 318 may be dimensioned to provide an interference fit with the received stroller frame support to increase friction therebetween and prevent slippage of the end connector body 310 along the received stroller frame. .

In the example shown in Figure 8, each end connector 302, 304 is disposed at an angle to each other to receive similarly angled stroller frame brackets. End connector body 310 defines a longitudinal axis 305. The connector body 310 of each end connector 302, 304 is disposed at an angle θ (eg, between about 90 ° and 180 °, preferably between about 100 ° and about 120 °) between its longitudinal axis 305 and a defined lateral axis 215 by the seat support. In this case, at least a portion of the first and second frame supports 110, 120 are angled to each other and the end connectors 302, 304 are similarly angled with respect to the lateral axis 215 of the seat support 210 to receive the first and second frame supports 110, 120. Once the end connectors 302, 304 are received by the first and second frame supports 110, 120, the end connectors 302, 304 can be moved into a position that provides a comfortable fit therebetween.

In some examples, the end connector body 310 includes a support bracket 320 (Figure 6) configured to receive a stabilizer, such as a cross bracket (for example, the sixth bracket 160 of the example stroller frame 100) or a protrusion (not shown) on the received frame support. Support bracket 320 receives

ES 2 640 127 T3 to the sixth support 160, as shown in Figures 1 and 2, to prevent the end connector 302, 304 from slipping relative to the frame support 110, 120 received past the sixth support.

To accommodate various stroller frames, in some implementations, seat support 210 includes an adjustable portion 216, as shown in FIG. 8, configured to modify the geometry of seat support 210. In some examples, the adjustable portion 216 includes a telescopic portion 217 for adjusting an overall width, W, of the seat support 210, thereby allowing the seat system 200 to be attached to various stroller widths. The adjustable portion 216 may also include a pivot 218 that allows movement of the first and second end portions 212, 214 of the seat support relative to each other for adaptation of the seat support 210 to allow attachment of the seat system 200 over various stroller frame configurations.
