Definitions
- This disclosure relates generally to strollers and, more particularly, to strollers with removable seats and related methods.
- Known strollers include a frame to support one or more seats and/or accessories (e.g., a basket).
- FIG. 1 is a right, front perspective view of an example stroller having two seats coupled to a frame of the stroller in accordance with the teachings of this disclosure.
- FIG. 2 is a right, front perspective view of an example seat including a seat mount that may be coupled to the example stroller frame of FIG. 1 in accordance with the teachings of this disclosure.
- FIG. 3 is a partial, right, front perspective view of the example stroller of FIG. 1 including a mount bar having a plurality of mount receivers to receive the seat mount of the example seat of FIG. 2 .
- FIG. 4 is a cross-sectional view of the example seat mount taken along the A-A line of FIG. 2 and a mount receiver of the example mount bar taken along the B-B line of FIG. 3 , the seat mount locked to the mount receiver.
- FIG. 5 is a left, rear perspective view of the example seat mount and a partial view of an example seat connection hub, napper bar, and a backrest arm of the example seat of FIG. 2 .
- FIGS. 6-8 are left, rear perspective views of the example seat mount and seat connection hub of FIG. 5 , showing the backrest arm and napper bar in different angular positions.
- FIG. 9 is a right, perspective view of the example seat of FIG. 2 , including the backrest arm and the napper bar in folded positions.
- FIG. 10 is a cross-sectional view of the example seat mount taken along the A-A line of FIG. 2 and a mount receiver of the example mount bar taken along the B-B line of FIG. 3 , the seat mount in a partially unlocked position relative to the mount receiver.
- FIG. 11 a cross-section view of the example seat mount and the example mount bar of FIG. 10 , the seat mount unlocked from the mount receiver.
- FIG. 12 is a flowchart representative of an example method disclosed herein for removably coupling a seat to a foldable stroller frame.
- Strollers typically include a frame and a seat supported by the frame to receive a child occupant.
- an accessory such as a basket
- some known strollers are limited with respect to a number of seats provided.
- some strollers include only one seat for one child. If a user wishes to carry a second child in the stroller, the user has to purchase a different stroller that includes two seats (e.g., a double stroller).
- a double stroller having two identical seats may not be appropriate if, for example, one child is capable of sitting upright but the other child cannot sit upright because of the child's age.
- a double stroller may be difficult to push if there is only one child in the stroller because of the extra unoccupied seat and/or uneven loading of the stroller.
- some known strollers do not provide for flexibility in accommodating different numbers of occupants and/or occupants of different ages.
- some known strollers include an expandable stroller frame which allows a user to move the stroller frame from a first width to a second width greater than the first width.
- the stroller In the non-expanded position having the first width, the stroller may have one seat coupled to the stroller frame. In the expanded position having the second width, two seats may be coupled to the stroller frame. To return the stroller to the non-expanded position, the user compresses the frame.
- such strollers are difficult for the user to manipulate, as these strollers require the user to reconfigure the stroller frame, including expanding the stroller frame before attaching the second seat.
- the stability of the stroller frame and, thus, the support provided by the stroller frame for one or more occupants seated in the seat(s) attached to the stroller frame may be compromised.
- example strollers for removably coupling one or more seats and/or accessories (e.g., baskets) to the stroller frame.
- the one or more seats and/or accessories are removably coupled to the stroller frame without changing a size of the stroller frame. Rather, one seat, two seats, or one seat and an accessory can be selectively coupled to the stroller frame without any adjustments to the frame itself.
- Example strollers frames disclosed herein selectively move between supporting one seat or accessory, one seat and an accessory, or two seats or accessories via a coupling mechanism between the stroller frame and the seat(s) and/or the accessory/accessories.
- Example stroller frames disclosed herein include a mount bar for supporting one or more seats and/or accessories coupled to the stroller frame.
- the mount bar includes a plurality of mount receivers. Each mount receiver receives a corresponding part of a seat or an accessory to removably secure the seat or the accessory to the stroller frame at one or more positions relative to the stroller frame (e.g., left, right, or middle).
- the seat or accessory includes a coupling mechanism that is controlled by a user (e.g., a child caretaker) to selectively lock or unlock the seat or the accessory to a mount receiver of the mount bar of the stroller frame.
- the mount bar of the stroller frame is a passive mechanical part that receives the coupling mechanism, thereby reducing the number of moving mechanical parts on the stroller frame.
- the coupling mechanism between the stroller frame and the seat(s) and accessories are same or substantially the same for each seat or accessory to provide for easy installation and removal of the seat or accessory by the user.
- example seats disclosed herein include a napper bar and backrest portion that can be selectively adjusted to release a lock that enables a handle of the seat to be pulled by the user. In such examples, the pulling of the handle releases a coupling between the seat and a mount receiver to which the seat mount is coupled and allows the seat to be removed from the mount receiver.
- example seats disclosed herein include multiple locking mechanisms to prevent instances of unintended disengagement between the seat and the stroller (e.g., by a child, by mechanical failure), which could result in injury to the child occupant.
- Example seats disclosed herein provide for ease of access for the user to removably attach the seat to the stroller frame while providing for a secure coupling between the stroller frame and the seat to protect the child occupant.
- a position of the one or more seats or accessories coupled to the example stroller frames can be varied with respect to (1) placement relative to a left side, a center, and/or a right side of the stroller and/or (2) orientation including forward- or rearward-facing or sideways relative to a direction of travel of the stroller.
- the placement and/or orientation of the one or more seats or accessories can be varied without modification to the stroller frame or the coupling mechanism between the seats or accessories and the stroller frame.
- the disclosed example strollers can receive different types of seats, such as an upright seat, a car seat, and/or a bassinet. In some disclosed examples, an upright seat and a bassinet can each be coupled to the stroller frame to accommodate differently aged children.
- One of the seats can be removed from the frame to reduce the occupancy of the stroller.
- the stroller can be used as a single-seat stroller.
- a basket accessory can be coupled to the stroller frame in place of the second seat to provide storage space.
- the seat(s) may be removed and only an accessory may be coupled to the frame such as, for example, one or more basket(s), and the frame may be used to transport items (e.g., groceries).
- An example stroller includes a wheeled frame, a receiver coupled to the frame, and a seat.
- the seat includes a hub; a mount; a lock disposed in the mount, the lock to move from a first positon to a second position when the mount is disposed in the receiver to removably couple the seat to the frame; a handle; and a pin disposed between the handle and the hub.
- the handle is moveable from a retracted position to an extended position when the pin is in a third position relative to the handle and the lock to move from the second position to the first position when the handle moves from the retracted position to the extended position.
- the hub includes a cam.
- the cam is to cause the pin to selectively engage a pocket of the handle.
- the pin in the third position, the pin is spaced apart from the pocket.
- the stroller further includes an actuator disposed in the mount.
- the actuator is to rotate to cause the lock to move to the second position when the handle moves to the extended position.
- the stroller further includes a plate slidably coupled to the handle. The actuator is to rotate via sliding of the plate.
- the stroller further includes a plate slidably coupled to the handle.
- the actuator is to rotate via sliding of the plate.
- the lock in the second position, the lock is disposed in an opening of the receiver and in the first position, the lock is retracted relative to the opening.
- the receiver is a first receiver and the stroller further includes a second receiver coupled to the frame.
- the seat is to be removably coupled to the first receiver or the second receiver.
- Another example stroller disclosed herein includes a wheeled frame; a mount bar coupled to the frame, the mount bar including a plurality of receivers; and a seat.
- the seat includes a hub, a mount, and a handle.
- the hub is to selectively enable the handle to move between an extended position and a retracted position to removably couple the mount to one of the plurality of receivers.
- the mount includes a lock and each of the receivers includes an opening.
- the handle is to cause the lock to move relative to the opening to removably couple the mount to the one of the plurality of receivers.
- each of the plurality of receivers includes a substantially frustoconical portion and the mount includes a substantially frustoconical portion.
- the seat further includes a pin disposed between the hub and the handle, the hub to selectively cause the pin to engage a pocket of the handle to lock the handle.
- the hub includes a cam to engage the pin when the handle is in the retracted position.
- the cam is spaced apart from the pin when the handle is in the extended position.
- the seat includes a backrest arm coupled to the hub and movement of the backrest arm from a first position to a second position is to cause the hub to rotate to enable the handle to move from the retracted position to the extended position.
- An example seat to be coupled to a frame of a stroller is disclosed herein.
- the example seat includes a hub, a mount, and a lock disposed in the mount.
- the lock is to move from a first position to a second position to removably couple the seat to the frame.

FIG. 12 is a flowchart representative of an example method disclosed herein for removably coupling a seat to a foldable stroller frame. - The figures are not to scale. Instead, to clarify multiple layers and regions, the thickness of the layers may be enlarged in the drawings. Wherever possible, the same reference numbers will be used throughout the drawing(s) and accompanying written description to refer to the same or like parts.
- Strollers typically include a frame and a seat supported by the frame to receive a child occupant. In some examples, an accessory, such as a basket, is also supported by the frame. However, some known strollers are limited with respect to a number of seats provided. For example, some strollers include only one seat for one child. If a user wishes to carry a second child in the stroller, the user has to purchase a different stroller that includes two seats (e.g., a double stroller). However, a double stroller having two identical seats may not be appropriate if, for example, one child is capable of sitting upright but the other child cannot sit upright because of the child's age. Also, a double stroller may be difficult to push if there is only one child in the stroller because of the extra unoccupied seat and/or uneven loading of the stroller. Thus, some known strollers do not provide for flexibility in accommodating different numbers of occupants and/or occupants of different ages.
- To provide for flexibility in the number of occupants, some known strollers include an expandable stroller frame which allows a user to move the stroller frame from a first width to a second width greater than the first width. In the non-expanded position having the first width, the stroller may have one seat coupled to the stroller frame. In the expanded position having the second width, two seats may be coupled to the stroller frame. To return the stroller to the non-expanded position, the user compresses the frame. However, such strollers are difficult for the user to manipulate, as these strollers require the user to reconfigure the stroller frame, including expanding the stroller frame before attaching the second seat. If the stroller frame is not properly secured in the expanded position or the non-expanded position, the stability of the stroller frame and, thus, the support provided by the stroller frame for one or more occupants seated in the seat(s) attached to the stroller frame may be compromised.
- Disclosed herein are example strollers for removably coupling one or more seats and/or accessories (e.g., baskets) to the stroller frame. In the disclosed examples, the one or more seats and/or accessories are removably coupled to the stroller frame without changing a size of the stroller frame. Rather, one seat, two seats, or one seat and an accessory can be selectively coupled to the stroller frame without any adjustments to the frame itself.
- Example strollers frames disclosed herein selectively move between supporting one seat or accessory, one seat and an accessory, or two seats or accessories via a coupling mechanism between the stroller frame and the seat(s) and/or the accessory/accessories. Example stroller frames disclosed herein include a mount bar for supporting one or more seats and/or accessories coupled to the stroller frame. The mount bar includes a plurality of mount receivers. Each mount receiver receives a corresponding part of a seat or an accessory to removably secure the seat or the accessory to the stroller frame at one or more positions relative to the stroller frame (e.g., left, right, or middle).
- In some disclosed examples, the seat or accessory includes a coupling mechanism that is controlled by a user (e.g., a child caretaker) to selectively lock or unlock the seat or the accessory to a mount receiver of the mount bar of the stroller frame. In some such examples, the mount bar of the stroller frame is a passive mechanical part that receives the coupling mechanism, thereby reducing the number of moving mechanical parts on the stroller frame. In some disclosed examples, the coupling mechanism between the stroller frame and the seat(s) and accessories are same or substantially the same for each seat or accessory to provide for easy installation and removal of the seat or accessory by the user.
- Some example seats disclosed herein include a napper bar and backrest portion that can be selectively adjusted to release a lock that enables a handle of the seat to be pulled by the user. In such examples, the pulling of the handle releases a coupling between the seat and a mount receiver to which the seat mount is coupled and allows the seat to be removed from the mount receiver. Thus, example seats disclosed herein include multiple locking mechanisms to prevent instances of unintended disengagement between the seat and the stroller (e.g., by a child, by mechanical failure), which could result in injury to the child occupant. Example seats disclosed herein provide for ease of access for the user to removably attach the seat to the stroller frame while providing for a secure coupling between the stroller frame and the seat to protect the child occupant.
- Further, a position of the one or more seats or accessories coupled to the example stroller frames can be varied with respect to (1) placement relative to a left side, a center, and/or a right side of the stroller and/or (2) orientation including forward- or rearward-facing or sideways relative to a direction of travel of the stroller. The placement and/or orientation of the one or more seats or accessories can be varied without modification to the stroller frame or the coupling mechanism between the seats or accessories and the stroller frame. Additionally, the disclosed example strollers can receive different types of seats, such as an upright seat, a car seat, and/or a bassinet. In some disclosed examples, an upright seat and a bassinet can each be coupled to the stroller frame to accommodate differently aged children. One of the seats can be removed from the frame to reduce the occupancy of the stroller. The stroller can be used as a single-seat stroller. In other examples, a basket accessory can be coupled to the stroller frame in place of the second seat to provide storage space. Also, in some examples, the seat(s) may be removed and only an accessory may be coupled to the frame such as, for example, one or more basket(s), and the frame may be used to transport items (e.g., groceries).
- An example stroller includes a wheeled frame, a receiver coupled to the frame, and a seat. The seat includes a hub; a mount; a lock disposed in the mount, the lock to move from a first positon to a second position when the mount is disposed in the receiver to removably couple the seat to the frame; a handle; and a pin disposed between the handle and the hub. The handle is moveable from a retracted position to an extended position when the pin is in a third position relative to the handle and the lock to move from the second position to the first position when the handle moves from the retracted position to the extended position.
- In some examples, the hub includes a cam. The cam is to cause the pin to selectively engage a pocket of the handle. In some such examples, in the third position, the pin is spaced apart from the pocket.
- In some examples, the stroller further includes an actuator disposed in the mount. The actuator is to rotate to cause the lock to move to the second position when the handle moves to the extended position. In some such examples, the stroller further includes a plate slidably coupled to the handle. The actuator is to rotate via sliding of the plate.
- In some examples, the stroller further includes a plate slidably coupled to the handle. The actuator is to rotate via sliding of the plate.
- In some examples, in the second position, the lock is disposed in an opening of the receiver and in the first position, the lock is retracted relative to the opening.
- In some examples, the receiver is a first receiver and the stroller further includes a second receiver coupled to the frame. The seat is to be removably coupled to the first receiver or the second receiver.
- Another example stroller disclosed herein includes a wheeled frame; a mount bar coupled to the frame, the mount bar including a plurality of receivers; and a seat. The seat includes a hub, a mount, and a handle. The hub is to selectively enable the handle to move between an extended position and a retracted position to removably couple the mount to one of the plurality of receivers.
- In some examples, the mount includes a lock and each of the receivers includes an opening. The handle is to cause the lock to move relative to the opening to removably couple the mount to the one of the plurality of receivers.
- In some examples, each of the plurality of receivers includes a substantially frustoconical portion and the mount includes a substantially frustoconical portion.
- In some examples, the seat further includes a pin disposed between the hub and the handle, the hub to selectively cause the pin to engage a pocket of the handle to lock the handle.
- In some examples, the hub includes a cam to engage the pin when the handle is in the retracted position. In some such examples, the cam is spaced apart from the pin when the handle is in the extended position.
- In some examples, the seat includes a backrest arm coupled to the hub and movement of the backrest arm from a first position to a second position is to cause the hub to rotate to enable the handle to move from the retracted position to the extended position.
- An example seat to be coupled to a frame of a stroller is disclosed herein. The example seat includes a hub, a mount, and a lock disposed in the mount. The lock is to move from a first position to a second position to removably couple the seat to the frame. The example seat includes a pin disposed between the handle and the hub. The handle is moveable from a retracted position to an extended position when the pin is in a third position relative to the handle and the lock is to move from the second position to the first position when the handle moves from the retracted position to the extended position.
- In some examples, the seat further includes a backrest arm to be rotatably coupled to the hub. In such examples, when the backrest arm is in a first position, the seat is in an unfolded position and when the backrest arm is in the second position, the seat is in a folded position. In some such examples, the handle includes a pocket. The pin is to be disposed in the pocket when the seat is in the unfolded position In some such examples, the pin is to move relative to the pocket during movement of the backrest arm from the first position to the second position.
- In some examples, the seat further includes a napper bar rotabably coupled to the hub, wherein rotation of the napper bar is to enable the handle to move between the retracted position and the extended position.
- In some examples, the mount includes an actuator and the lock is to operatively coupled to the actuator. The handle is to cause the actuator to rotate when the handle moves from the retracted position to the extended position. The lock is to move relative to the frame based on the rotation of the actuator.
- Turning to the figures,
FIG. 1 is a right, front perspective view of anexample stroller 100 constructed in accordance with the teachings of this disclosure. Theexample stroller 100 illustrated inFIG. 1 includes aframe 102 having afirst side 104 and asecond side 106. Thefirst side 104 and thesecond side 106 of thestroller frame 102 include a plurality of frame members and wheels attached to the frame members. The frame members and wheels of thefirst side 104 of thestroller frame 102 will be described herein with the understanding that thesecond side 106 is a mirror image of thefirst side 104. Thus, thesecond side 106 includes substantially identical frame members and wheels as thefirst side 104 and, in the interest of brevity, will not be repeatedly detailed herein. - In the illustrated
example stroller 100, thefirst side 104 includes anarm 108 extending from aparent handle 110. The parent handle 110 is disposed between thefirst side 104 and thesecond side 106 of thestroller frame 102. In some examples, thearm 108 and the parent handle 110 are integrally formed from a unit such as, for example, a tube. In some examples, a height of the parent handle 110 is adjustable via adjustment of height of thearm 108. - The
first side 104 of thestroller frame 102 also includes afront leg 112 and arear leg 114. Afront wheel 116 is rotatably coupled to thefront leg 112. In some examples, thefront wheel 116 is rotatably coupled to afront bar 118 that extends between thefirst side 104 and thesecond side 106. Arear wheel 120 is coupled to therear leg 114. In some examples, arear wheel 120 is coupled to arear bar 122 that extends between thefirst side 104 and thesecond side 106. Although theexample stroller 100 ofFIG. 1 includes four wheels (e.g., twofront wheels 116 and tworear wheels 120 coupled to the first andsecond sides - In the illustrated example, the
front leg 112 and therear leg 114 are coupled via a joint 124. Therear leg 114 and thearm 108 are coupled via a hub 126 (e.g., a second joint). The joint 124 and thehub 126 facilitate folding of the stroller such thatfront leg 112 and thearm 108 and, thus, the parent handle 110 are free to rotate relative to therear leg 114. - The
example stroller 100 ofFIG. 1 includes afirst seat 128 disposed between thefirst side 104 and thesecond side 106 and asecond seat 130 disposed between thefirst side 104 and thesecond side 106. In some examples, thestroller 100 only includes oneseat FIG. 1 . For example, bothseats stroller 100 or can face in different directions (e.g., as illustrated inFIG. 1 ). Each of the first andsecond seats seat frame 132 mounted to thestroller frame 102. Theseat frame 132 defines abackrest portion 133 of the seat 128 (e.g., a portion against which an occupant of the seat rests his or back when sitting in theseat 128, 130) and a support portion 135 (e.g., a portion that supports a body of the seat occupant). The seat(s) 128, 130 can include accessories attached to the respective seat frames 132, such as soft goods, a canopy, a footrest, etc. In some examples, thesecond seat 130 is substantially the same as thefirst seat 128. - In the
example stroller 100 ofFIG. 1 , thefirst seat 128 and thesecond seat 130 are removably coupled to thestroller frame 102 via respective seat mounts of the seat frames 132. The seat mount(s) of the seat(s) 128, 130 are coupled to a mount bar of thestroller frame 102. For example purposes, the removable coupling of a seat to thestroller frame 102 will be discussed in connection with thefirst example seat 128 ofFIG. 1 , with the understanding thesecond example seat 130 can be coupled to thestroller frame 102 in the same or substantially the same manner as disclosed in connection with thefirst seat 128. -
FIG. 2 is a right, front perspective view of thefirst example seat 128 ofFIG. 1 . Theexample seat 200 includes means for coupling theseat 128 to a mount bar of the stroller frame. As shown inFIG. 2 , thefirst example seat 128 includes aseat mount 200 coupled to theseat frame 132. In operation, theseat mount 200 is coupled to a ground-facing surface of thesupport portion 135 of theseat frame 132, or side of theseat frame 132 opposite a side on which a child sits. As also shown inFIG. 2 , thefirst example seat 128 includes anapper bar 202 extending between afirst side 204 and asecond side 206 of theseat frame 132. Thenapper bar 202 is coupled to theseat frame 132 via respectiveseat connection hubs 208 disposed at the first side 204 (shown inFIG. 2 ) and thesecond side 206 of theseat frame 132. Theseat connection hubs 208 enable rotation of thenapper bar 202 relative to theseat frame 132 when a user exerts a force on the napper bar 202 (e.g. presses down on the napper bar 202). - The
example seat frame 132 also includesbackrest arms 203 at the first andsecond sides seat 128 that define thebackrest portion 133 of theseat 128. Thebackrest arms 203 are rotatably coupled to the respectiveseat connection hubs 208. In some examples, thebackrest arms 203 rotate substantially simultaneously via thehubs 208. Thebackrest arm 203 can rotate toward the napper bar 202 (e.g., to fold the seat 128) or away from the napper bar 202 (e.g., to adjust a recline angle of thebackrest portion 133 of the seat 128). As disclosed below in connection withFIGS. 3-8 , theexample napper bar 202 and thebackrest arms 203 can be selectively rotated by a user via theseat connection hubs 208 to releaseseat mount 200 from thestroller frame 102 such that thefirst example seat 128 can be removed or detached from thestroller frame 102. In some examples, thenapper bar 202 and thebackrest arms 203 are selectively rotated via theseat connection hubs 208 to couple theseat 128 to thestroller frame 102. -
FIG. 3 is a partial, right, front perspective view of the example stroller ofFIG. 1 . As shown inFIG. 3 , theexample stroller frame 102 includes amount bar 300. Themount bar 300 extends between the first andsecond sides stroller frame 102. In the example ofFIG. 3 , themount bar 300 is disposed proximate to the joint 124 between thefront leg 112 and therear leg 114 of thestroller frame 102. In some examples, themount bar 300 ofFIG. 3 is a cast part coupled to theexample stroller frame 102. In some examples, themount bar 300 is integral with thestroller frame 102. - The
example mount bar 300 ofFIG. 3 includes means for receiving a seat mount of a seat, such as theexample seat mount 200 of thefirst seat 128 ofFIG. 2 . For example, theexample mount bar 300 ofFIG. 3 includes afirst mount receiver 302, asecond mount receiver 304, and athird mount receiver 306. The first, second, and third mount receiver(s) 302, 304, 306 can include cavities oropenings 310 formed in themount bar 300. In some examples, themount bar 300 and the first, second, andthird mount receivers mount bar 300 and coupled to the mount bar 300 (e.g., via fastener(s) such as screw(s)). Theexample mount bar 300 and the first, second, and thirdexample mount receivers example mount bar 300 can include additional or fewer mount receivers than illustrated inFIG. 3 . Also, although the first, second, andthird mount receivers mount bar 300, the receivers can be arranged in other patterns such as, for example, a triangular pattern. - In the example of
FIG. 3 , the each of the first, second, and thirdexample mount receivers third mount receivers shell 308 having a substantially frustoconical or funnel-shape. The first, second, andthird mount receivers shell 308 of each of themount receivers opening 310. As disclosed herein, the shapes of the first, second, andthird mount receivers seat mount 200 ofFIG. 2 ) or an accessory to be coupled to thestroller frame 102. - In the example of
FIG. 3 , thefirst mount receiver 302 is disposed proximate to thesecond side 106 of thestroller frame 102, thethird mount receiver 306 is disposed proximate to thefirst side 104 of the stroller frame, and thesecond mount receiver 304 is disposed between thefirst mount receiver 302 and the second mount receiver 306 (e.g., proximate to a longitudinal axis extending through a center of the mount bar 300). Thus, one or more seats and/or accessories can be coupled to thestroller frame 102 at different positions. Theexample stroller frame 102 ofFIGS. 1 and 3 can support a single seat or accessory and/or two more seats or accessories in any of the mount receivers without the risk thestroller frame 102 becomes unstable. - For example, the
first seat 128 can be mounted to thestroller frame 102 via thesecond mount receiver 304 such that a longitudinal axis extending through a center of thefirst seat 128 is substantially aligned with a longitudinal axis extending through a center of themount bar 300. In other examples, a center of thefirst seat 128 is positioned right or left relative to the center of themount bar 300 via thefirst mount receiver 302 or thethird mount receiver 306. Put another way, the center of thefirst seat 128 can be disposed closer to thefirst side 104 or thesecond side 106 of theexample stroller 100. In some examples, thefirst seat 128 is coupled to thefirst mount receiver 302 and thesecond seat 130 is coupled to the third mount receiver 306 (e.g., as illustrated inFIG. 1 ). In some such examples, a portion of theseat frame 132 may overhang in thestroller frame 102 when thefirst seat 128 and/or thesecond seat 130 is coupled proximate to the first orsecond sides stroller frame 102 via the first and/orthird mount receivers third mount receivers stroller 100. In some examples, the seat(s) and/or accessories can be coupled to thestroller frame 102 sideways relative to the direction of travel (e.g., via thefirst mount receiver 302 and/or the third mount receiver 306). -
FIG. 4 is a cross-sectional view of theexample seat mount 200 of thefirst example seat 128 taken along the A-A line ofFIG. 2 and the secondexample mount receiver 304 of theexample mount bar 300 taken along the B-B line ofFIG. 3 . In the example ofFIG. 4 , theseat mount 200 is locked to thesecond mount receiver 304 and, thus, thefirst example seat 128 is coupled to thestroller frame 102. AlthoughFIG. 4 is discussed in connection with thefirst example seat 128, another seat (e.g., thesecond example seat 130 ofFIG. 1 ) and/or accessory (e.g., a basket) can be coupled to thestroller frame 102 in a substantially similar manner as disclosed herein. Also, althoughFIG. 4 is discussed in connection with the second (e.g., middle)mount receiver 304 of themount bar 300 ofFIG. 3 , theseat mount 200 of the example seat 128 (or another seat and/or accessory) can be coupled to thestroller frame 102 via thefirst mount receiver 302 and/or thethird mount receiver 306 in substantially the same manner as disclosed herein in connection with thesecond mount receiver 304. - As illustrated in
FIG. 4 , thesecond mount receiver 304 of theexample mount bar 300 and theseat mount 200 of thefirst example seat 128 have complementary shapes. In the example ofFIG. 4 , theshell 308 of thesecond mount receiver 304 has a substantiallyfrustoconical portion 400 and a substantiallysquare portion 402. In some examples, the substantiallysquare portion 402 includes a surface on which theseat mount 200 rests when disposed in the second mount receiver 304 (e.g., thecavity 310 is close-ended). In other examples, the substantiallysquare portion 402 does not include such a surface (e.g., thecavity 310 is open-ended). Also, theseat mount 200 has a substantiallyfrustoconical portion 404 and a substantiallysquare portion 406 such that theseat mount 200 can be inserted into thecavity 310 of thesecond mount receiver 304. In operation, the complementary shapes of thesecond mount receiver 304 of thestroller frame 102 and theseat mount 200 of theseat 128 provide for coupling of theseat 128 to thestroller frame 102 without requiring exact alignment between theseat mount 200 and thecavity 310 of thesecond mount receiver 304 when the user is inserting theseat mount 200 into thecavity 310. In particular, because of thefrustoconical portion 400 of the secondexample mount receiver 304, theseat mount 200 is guided into thesecond mount receiver 304 without requiring precise alignment of theseat mount 200 and thesecond mount receiver 304 by the user. For example, to insert theseat mount 200 in thesecond mount receiver 304, the user positions theseat mount 200 of theseat 128 over thesecond mount receiver 304 and lowers theseat 128 onto thestroller frame 102 such that theseat mount 200 is received in thecavity 310 of thesecond mount receiver 304. In some examples, the user may not have aligned (e.g., exactly aligned) the respectivesquare end portions second mount receiver 304 and theseat mount 200. As a result, thesquare end portion 406 of theseat mount 200 enters thesecond mount receiver 304 at an angle or offset relative to thesquare end portion 402 of thesecond mount receiver 304. In such examples, thefrustoconical portion 400 of thesecond mount receiver 304 facilities placement of thesquare end portion 406 of theseat mount 200 into thesquare end portion 402 of thesecond mount receiver 304. In particular, the curved or sloped surface of thefrustoconical portion 400 allows thesquare end portion 406 of theseat mount 200 to slide into thesquare end portion 402 of thesecond mount receiver 304 to couple theexample seat 128 to theexample stroller frame 102. Thus, the secondexample mount receiver 304 provides for self-alignment of theseat mount 200, thereby reducing potential user difficulties in coupling theseat 128 to thestroller frame 102 and any risks that theseat 128 is not securely coupled to thestroller frame 102. - Referring the
example seat mount 200 of thefirst example seat 128, theseat mount 200 includes abase 408 and means for coupling theseat mount 200 to themount bar 300, or acoupler 410 extending from thebase 408. Thecoupler 410 can include a protrusion extending from thebase 408. As illustrated inFIG. 4 , when theseat mount 200 is coupled to themount bar 300, thecoupler 410 is disposed in thecavity 310 of thesecond mount receiver 304 and thebase 408 is disposed on (e.g., sits on) asurface 412 of themount bar 300. The base 408 can be coupled to a surface of the seat 128 (e.g., the ground-facing surface of thesupport portion 135 of the stroller frame 132) or an accessory via one or more mechanical or chemical fasteners. - The
example seat mount 200 includes means for releasing theseat mount 200 from one of themount receivers mount bar 300. For example, theseat mount 200 includes arelease handle 414. Afirst end 416 of the example release handle 414 includes agrip portion 418 that can be accessed by a user. Asecond end 420 of therelease handle 414 is disposed in aslot 422 defined by thebase 408 of theseat mount 200. In the example ofFIG. 4 , thegrip portion 418 of therelease handle 414 is disposed proximate to thebackrest portion 133 of the seat 128 (e.g.,FIGS. 1, 2 ). Such a location of thegrip portion 418 of therelease handle 414 prevents unintended access to the release handle 414 by the occupant of theseat 128 during use of thestroller 100. - In the example of
FIG. 4 , afirst plate 424 is coupled to thesecond end 420 of therelease handle 414. Asecond plate 426 is disposed between thefirst plate 424 and thesecond end 420 of therelease handle 414. Thesecond plate 426 is slidably coupled to therelease handle 414. As disclosed herein, when the release handle 414 moves from a locked positon to an unlocked position, thesecond plate 426 slides relative to thecoupler 410 to unlock theseat mount 200 from themount bar 300. Therelease handle 414 and thesecond plate 426 are slidably coupled to thebase 408 viafasteners 428 that extend throughopenings 429 in thefirst plate 424, openings in thesecond plate 426, and openings in therelease handle 414. - The
example seat mount 200 includes means for driving the locking of theseat mount 200 to thesecond mount receiver 304. For example, theseat mount 200 ofFIG. 4 includes anactuator 430 disposed in thecoupler 410. Theactuator 430 includes apinion 432. As illustrated inFIG. 4 , thepinion 432 extends through afirst opening 434 formed in therelease handle 414 andsecond opening 436 formed in thesecond plate 426. As disclosed herein, thepinion 432 selectively engages arack 506 of the second plate 426 (FIG. 5 ). Theactuator 430 is coupled to the first plate 424 (e.g., via an interference fit between a portion of thefirst plate 424 and theactuator 430 via a mechanical fastener, etc.). - The
example seat mount 200 includes means for locking theseat mount 200 to thesecond mount receiver 304. For example, theseat mount 200 ofFIG. 4 includes afirst lock 438 and asecond lock 440. The first andsecond locks respective openings 442 formed in thecoupler 410. Each of the first andsecond locks teeth 444. Thepinion 432 of theactuator 430 selectively engages theteeth 444 of the first andsecond locks second locks - The
example seat mount 200 includes means for driving the means for locking theseat mount 200 to thesecond mount receiver 304. For example, afirst spring 446 is disposed between thefirst lock 438 and theactuator 430. Asecond spring 448 is disposed between thesecond lock 440 and theactuator 430. As illustrated inFIG. 4 , thefirst spring 446 is disposed between awall 450 of thefirst lock 438 and afirst projection 452 formed in thecoupler 410 proximate to theactuator 430 and thesecond spring 448 is disposed awall 454 between thesecond lock 440 and asecond projection 455 formed in thecoupler 410 proximate to theactuator 430. The first andsecond locks second springs seat mount 200 to and unlocking of theseat mount 200 from the secondexample mount receiver 304. When thecoupler 410 is disposed in the secondexample mount receiver 304, the first andsecond springs second springs second locks actuator 430, through theopenings 442 of thecoupler 410 and intorespective notches 456 formed in thesecond mount receiver 304 to couple theseat mount 200 to themount receiver 304. - The retraction and expansion of the first and
second locks release handle 414 into and partially out of theslot 422 of thebase 408, as represented by thearrow 458 ofFIG. 4 . For example, a user can grasp thegrip portion 418 to pull the release handle 414 outward relative to theseat mount 200. As disclosed herein, when the user pulls thegrip portion 418 of the release handle 414 outward relative to theseat mount 200, thesecond plate 426 slides with therelease handle 414, and therack 506 of thesecond plate 426 causes thepinion 432 of theactuator 430 to rotate and the first andsecond locks FIG. 4 to a retracted position. - The
example seat mount 200 includes means for controlling therelease handle 414. In the example ofFIG. 4 , the ability of the user to pull therelease handle 414 is controlled by alock pin 460 disposed between therelease handle 414 and theseat connection hub 208 of thefirst example seat 128 ofFIG. 4 . In the example ofFIG. 4 , afirst end 462 of thelock pin 460 is disposed in apocket 464 of therelease handle 414. Asecond end 466 of thelock pin 460 selectively engages means for positioning thelock pin 460 relative to thepocket 464. For example, thesecond end 466 of thelock pin 460 engages acam 468 disposed in ahousing 469 of theseat connection hub 208. Although inFIG. 4 thelock pin 460 is shown as engaging theseat connection hub 208 located at thesecond side 206 of thefirst example seat 128, thelock pin 460 could alternatively engage theseat connection hub 208 located at thefirst side 204 of the first example seat (FIG. 2 ). In some examples, theseat mount 200 includes twolock pins 460 that engage the respectiveseat connection hubs 208 located at the first andsecond sides first example seat 128. In such examples, therelease handle 414 includes twopockets 464 to receive the respective lock pins 460. - The
example lock pin 460 includes means for driving thelock pin 460. In the example ofFIG. 4 , thelock pin 460 includes aspring 470. In the example ofFIG. 4 , when thelock pin 460 engages thecam 468 and thespring 470 is compressed, the spring-loadedlock pin 460 is disposed in thepocket 464 of therelease handle 414. In such examples, thelock pin 460 prevents sliding of the release handle 414 (e.g., the user cannot pull thegrip portion 418 outward relative to the seat mount 200) due to the presence of thelock pin 460 in thepocket 464. As disclosed in greater detail below, rotation of the backrest arm(s) 203 and the napper bar 202 (FIG. 2 ) via theseat connection hub 208 causes thelock pin 460 to move out of thepocket 464 of therelease handle 414. In examples including twolock pins 460, rotation of theseat connection hubs 208 can cause the lock pins 460 to move out of thepockets 464 at substantially the same time. The release of the lock pin(s) 460 from the pocket(s) 464 enables thegrip portion 418 of therelease handle 414 to be pulled by the user, which causes the first andsecond locks seat mount 200 to be removed from thesecond mount receiver 304. -
FIG. 5 is a left, rear perspective view of theexample seat mount 200 and a partial view of one of theseat connection hub 208, thenapper bar 202 and one of thebackrest arms 203 of thefirst example seat 128 ofFIG. 2 . In some examples ofFIG. 5 , theseat mount 200 is coupled to first, second, orthird mount receivers example mount bar 300 of thestroller 100 ofFIGS. 1 and 3 . However, for illustrative purposes, themount bar 300 and themount receivers FIG. 5 . In other examples ofFIG. 5 , theseat mount 200 is not coupled (or not yet coupled) to themount bar 300. - As shown in
FIG. 5 , thelock pin 460 is disposed in thepocket 464 of therelease handle 414. As disclosed above, although thelock pin 460 is shown proximate to thefirst side 204 of theseat 128 inFIG. 5 , thelock pin 460 could be disposed proximate to thesecond side 206 of the seat 128 (e.g., as inFIG. 4 ). In some examples, afirst lock pin 460 is disposed proximate to thesecond side 206 of theseat 128 and asecond lock pin 460 is disposed proximate to thefirst side 204 of theseat 128. - As also shown in
FIG. 5 , thebackrest arm 203 is coupled to theseat connection hub 208 via afirst connector 500. Thefirst connector 500 is at least partially disposed in thehousing 469 of thehub 208. Thefirst connector 500 is pivotably coupled to thehousing 469 to enable thebackrest arm 203 to move between one or more angular positions relative to thehousing 469. Also, thenapper bar 202 is coupled to theseat connection hub 208 via asecond connector 502. Thesecond connector 502 is pivotably coupled to thehousing 469 to enable the napper bar to move between one or more angular positions relative to thehousing 469. In the example ofFIG. 5 , thebackrest arm 203 is in a first angular position and thenapper bar 202 is in a second angular position spaced apart from thebackrest arm 203. In some examples, the first angular position of thebackrest arm 203 corresponds to a position in which thebackrest portion 133 of theseat 128 is in a substantially upright position (e.g., substantially perpendicular relative to thesupport portion 135 ofFIG. 1 , at a recline relative to the support portion 135) such that an occupant of theseat 128 could rest his or her back against thebackrest portion 133. - For illustrative purposes, the
first plate 424 is shown as transparent relative to thesecond plate 426 inFIG. 5 . As shown inFIG. 5 , thesecond plate 426 includesopenings 504 through which thefasteners 428 extend to couple the first andsecond plates release handle 414 to thebase 408. As also shown inFIG. 5 , thesecond plate 426 includes therack 506 having a plurality of teeth at least partially extending in theopening 436 of thesecond plate 426. Thepinion 432 of theactuator 430 selectively engages therack 506, as disclosed above. As also shown inFIG. 5 , thesecond lock 440 is in an expanded position (and thefirst lock 438 is in an expanded position as shown inFIG. 4 ). - In some examples, the user may wish to retract the
locks seat mount 200 to enable theseat 128 to be removed from thestroller frame 102. In other examples, the user may wish to retract thelocks seat mount 200 into the first, second, orthird mount receivers mount bar 300.FIGS. 6-8 illustrate the unlocking of therelease handle 414 via thelocking pin 460, which enables the user to pull therelease handle 414 to retract thelocks seat mount 200. -
FIGS. 6-8 are left, rear perspective views of the example seat mount and seat connection hub ofFIG. 5 , showing the backrest arm and napper bar in different angular positions. For illustrative purposes, a portion of therelease handle 414 is shown in a cutaway view with respect to thepocket 464 for receiving thelock pin 460 inFIGS. 6 and 7 . AlthoughFIGS. 6-8 illustrate one lock pin and seat connection hub, the release oflock pin 460 shown inFIGS. 6-8 can apply to examples including twolock pins 460 associated with theseat connection hubs 208 at each side of theseat 128. - As illustrated in
FIG. 6 , thesecond end 466 of thelock pin 460 engages thecam 468 of theseat connection hub 208. In the example ofFIG. 6 , thecam 468 is coupled to thefirst connector 500 of theseat connection hub 208, or the connector to which thebackrest arm 203 is coupled. In some examples, thefirst connector 500 and thecam 468 are formed from one or more molds, from two or more separate pieces mechanically or chemically coupled together, etc. Also, inFIG. 6 , thespring 470 is in a compressed position. As shown inFIG. 6 , thespring 470 is disposed between acollar 600 of thelock pin 460 and thepocket 464. Thus,first end 462 of thelock pin 460 is held in thepocket 464 of the release handle 414 by the engagement of thesecond end 466 of thelock pin 460 withcam 468, which acts on thespring 470. - To release the
lock pin 460 from thepocket 464 of therelease handle 414, the user rotates thebackrest arm 203 toward the napper bar 202 (e.g., pushes thebackrest arm 203 toward thesupport portion 135 of the seat 128), as represented by thearrow 602 ofFIG. 6 . Thefirst connector 500 rotates via theseat connection hub 208, which enables thebackrest arm 203 coupled thereto to move toward thenapper bar 202. As thebackrest arm 203 pivots toward thenapper bar 202, thecam 468 moves away from thesecond end 466 of thelock pin 460 due to the movement (e.g., rotation) of thefirst connector 500, as represented by thearrow 604 ofFIG. 6 . Put another way, during rotation of thebackrest arm 203 and thefirst connector 500, thecam 468 becomes spaced apart from thesecond end 466 of thelock pin 460 such that thecam 468 no longer engages thesecond end 466 of thelock pin 460. - As the
backrest arm 203 rotates toward thenapper bar 202 via thefirst connector 500 and theseat connection hub 208, thesecond end 466 of thelock pin 460 no longer engages thecam 468. Thus, the tension of thespring 470 is released and thespring 470 moves from a compressed position to an extended position. As a result of the release of thespring 470, thefirst end 462 of thelock pin 460 moves out of thepocket 464 and no longer engages the pocket 464 (e.g., thefirst end 462 is moved a distance from the pocket 464), as represented by thearrow 700 ofFIG. 7 . Put another way, thelock pin 460 is sprung back relative to thepocket 464. - In some examples, as the user rotates the
backrest arm 203, thebackrest arm 203 engages thenapper bar 202, which causes thenapper bar 202 to move toward thesupport portion 135 of theseat 128. Thus, in some examples, theseat 128 folds or substantially folds as a result of the rotation of the backrest arm(s) 203 and thenapper bar 202 such that thebackrest portion 133 is disposed proximate to thesupport portion 135, which is disclosed below inFIG. 9 . - As shown in
FIG. 8 , when thebackrest arm 203 and thenapper bar 202 are rotated such that thebackrest arm 203 andnapper bar 202 are substantially collapsed, thelock pin 460 is no longer disposed in thepocket 464 of therelease handle 414. Thus, therelease handle 414 is free to slide relative to theslot 422 of thebase 408. As represented by thearrow 800 inFIG. 8 , a user can grasp thegrip portion 418 of therelease handle 414 and pull the release handle 414 outward relative to thecoupler 410 of theseat mount 200. As a result of the pulling of therelease handle 414, anedge 802 of thesecond end 420 of the release handle 414 moves a distance x away from anedge 804 of theslot 422. - When the user pulls the release handle 414 outward, the
second plate 426 of theseat mount 200 slides with therelease handle 414. For example, theopenings 504 of thesecond plate 426 move (e.g., slide) relative to thefasteners 428 extending through theopenings 504 from thefirst plate 424, as represented by thearrows 806 ofFIG. 8 . The sliding of thesecond plate 426 causes thepinion 432 of theactuator 430 to rotate as a result of the engagement of thepinion 432 with therack 506, as represented by thearrow 808 ofFIG. 8 . In some examples, the amount by which thesecond plate 426 slides and, thus, the distance x by which the release handle 414 slides relative to theedge 804 of theslot 422 is defined by a size and/or a number of teeth of therack 506, a length of theopenings openings pinion 432 causes thelocks seat mount 200 to retract. -
FIG. 9 is a right, perspective view of theexample seat 128 in a substantially folded position, or a position in which the backrest arm(s) 203 and thenapper bar 202 are substantially collapsed and, thus, thebackrest portion 133 is disposed proximate to thesupport portion 135. For example, a user may rotate the backrest arm(s) 203 and thenapper bar 202 via theseat connection hub 208 to the positions shown inFIG. 9 to unlocklock pin 460 from the release handle 414 as disclosed above in connection withFIGS. 5-8 . In addition to releasing thelock pin 460 to enable the user to pull the release handle 414 of theseat mount 200, the folded position of theseat 128 shown inFIG. 9 provides for increase ease of access to the release handle 414 as compared to if the user had to reach around and under thebackrest portion 133 of theseat 128 while thebackrest portion 133 was substantially upright. In some examples, a degree to which thebackrest arm 203 and thenapper bar 202 rotate and theseat 128 folds is defined by the seat connection hub 208 (e.g., one or more stops disposed in thehousing 469 of the seat connection hub 208). -
FIG. 10 is a cross-sectional view of theexample seat mount 200 of thefirst example seat 128 taken along the A-A line ofFIG. 2 and the secondexample mount receiver 304 of theexample mount bar 300 taken along the B-B line ofFIG. 3 , with theseat mount 200 assembled in thesecond mount receiver 304. In the example ofFIG. 10 , theseat mount 200 is partially unlocked to the second mount receiver 304 (i.e., as compared to the example ofFIG. 4 in which theseat mount 200 is locked to the second mount receiver 304). - As shown in
FIG. 10 , thelock pin 460 is disengaged from the cam 468 (e.g., as a result of rotation of thebackrest arm 203 and the napper bar 202) and thefirst end 462 of thelock pin 460 is removed from thepocket 464 of therelease handle 414. Thus, the release handle is free to be pulled outward relative to the coupler 410 (e.g., via the grip portion 418), as represented by thearrow 1000 ofFIG. 10 . - As disclosed above, when the
release handle 414 is pulled outward relative to thecoupler 410, thesecond plate 426 slides with therelease handle 414. The sliding of thesecond plate 426 causes thepinion 432 of theactuator 430 to rotate via therack 506 of the second plate 426 (FIGS. 5, 8 ). As thepinion 432 rotates as a result of the sliding of thesecond plate 426 in the direction of the movement of therelease handle 414, thepinion 432 engages theteeth 444 of the first andsecond locks pinion 432 and the engagement of thepinion 432 with theteeth 444 of the first andsecond locks second locks actuator 430 and the first andsecond springs second locks notches 456 of thesecond mount receiver 304, as represented by thearrows FIG. 10 . In examples, the first andsecond locks respective openings 442 of thecoupler 410. -
FIG. 11 shows theexample seat mount 200 removed from thesecond mount receiver 304. As illustrated inFIG. 11 , the retraction of thelocks notches 456 of thesecond mount receiver 304 enables theseat mount 200 to be removed from the second mount receiver 304 (and, thus, the seat or accessory to which theseat mount 200 is coupled from the stroller 100). For example, a user may lift theseat 128 out of thesecond mount receiver 304 while grasping, for example, thegrip portion 418 of therelease handle 414 and one or more portions of theseat 128, such as thesupport portion 135. - If the user wishes to re-attach the
first example seat 128 including theseat mount 200 or to couple another seat or accessory having theseat mount 200 to themount bar 300, the user inserts theseat mount 200 into the second mount receiver 304 (or the first orthird mount receivers 302, 306) by aligning or substantially aligning thecoupler 410 of theseat mount 200 with the substantiallysquare portion 402 of theshell 308 of thesecond mount receiver 304. In some examples, therelease handle 414 is in an unlocked position when theseat mount 200 is inserted into the mount receiver 340 (e.g., as a result of a user folding thebackrest arm 203 so as to release thelock pin 460 and holding and/or pulling thegrip portion 418 of the release handle 414 while inserting theseat mount 200 into the second mount receiver 304). Thus, the first andsecond locks coupler 410 is inserted into the mount receiver 304 (e.g., thebase 408 of theseat mount 200 engages thesurface 412 of the mount bar 300), the user may lock the release handle 414 by pushing the release handle 414 inward relative to thecoupler 410. In other examples, the release handle 414 automatically moves inward or retracts when the user releases thegrip portion 418 of therelease handle 414. - As the release handle 414 moves to the retracted position, the
second plate 426 slides in the direction of the movement of therelease handle 414, or toward theedge 804 of the slot 422 (e.g., such that the distance x between theedge 802 of therelease handle 414 and theedge 804 of theslot 422 decreases as compared to the example ofFIG. 8 ). The sliding of thesecond plate 426 as a result of the movement of the release handle 414 causes thepinion 432 of theactuator 430 to rotate due to the engagement of thepinion 432 with therack 506 of thesecond plate 426. When thesecond plate 426 slides toward theedge 804 of theslot 422 due to the movement of therelease handle 414, thepinion 432 rotates in a direction opposite the direction of rotation of thepinion 432 when thesecond plate 426 moves away from theedge 804 of theslot 422 and the release handle 414 moves the extended position. The rotation of thepinion 432 during movement of therelease handle 414 to the retracted position causes the first andsecond locks actuator 430 via the engagement of theteeth 444 of the first andsecond locks pinion 432. The first andsecond locks respective notches 456 of, for example, thesecond mount receiver 304 to lock theseat mount 200 to thesecond mount receiver 304. In some examples, therespective springs second locks locks - In some such examples, after the user has released the release handle 414 (e.g., after pushing the handle inward) and the
locks notches 456 of thesecond mount receiver 304, the user moves the backrest arm(s) 203 away from thesupport portion 135 of theseat 128 to move theseat 128 from the folded position shown inFIG. 9 to the unfolded position shown inFIG. 2 . In such examples, thefirst connector 500 of theseat connection hub 208 rotates such that thecam 468 re-engages or pushes on thesecond end 466 of thelock pin 460 and causes thefirst end 462 of thelock pin 460 to move into thepocket 464 of therelease handle 414, thereby locking therelease handle 414. In some examples, the user further moves the backrest arm(s) 203 to adjust a recline angle of thebackrest portion 133 of theseat 128. In some examples, the user moves thenapper bar 202 from the folded position to a desired height relative to thesupport portion 135 of theseat 128. - Thus,
FIGS. 4-11 illustrate the removably secure coupling of theexample seat mount 200 ofFIGS. 2 and 9 to theexample stroller frame 102 ofFIGS. 1 and 3 . As illustrated inFIGS. 3, 4, 10, and 11 the mount receiver(s) 302, 304, 306 are passive mechanical parts that do not include moving parts. Rather, theexample seat 128 includes components that provide for locking of theseat mount 200 to one of themount receivers example seat mount 200 includes at least two locking mechanisms including (1) the lock pin(s) 460 which prevents unintended movement of therelease handle 414 and (2) thelocks coupler 410 of theseat mount 200 to one of themount receivers actuator 430 and thesecond plate 426. Providing the locking mechanism(s) via theseat mount 200 reduces the number of components on thestroller frame 102 and, thus, reduces the potential for components on thestroller frame 102 and theseat 128 to fail or to improperly engage. Providing the locking mechanism(s) via theseat mount 200 also increases user control over the locking of theseat 128 to thestroller frame 102, as the operation of theseat mount 200 is controlled by the user via the backrest arm(s) 203, thenapper bar 202, and therelease handle 414. Because the mount receiver(s) 302, 304, 306 are mechanically passive components, once the user releases therelease handle 414 after inserting theseat mount 200 into one of themount receivers seat 128 is locked to theframe 102 via activation of thelocks seat mount 200 without wondering if any components in thestroller frame 102 have properly reacted to the insertion of theseat mount 200. Further, the seats and/or accessories can be coupled to the mount receiver(s) 302, 304, 306 in different orientations (e.g., forward-facing or rearward-facing relative to the direction of travel of the stroller 100) without the user having to make any adjustments to the stroller frame. -
FIG. 12 is a flowchart illustrating anexample process 1200 for removably coupling a seat or accessory (e.g., theseat example process 1200 is disclosed with respect to the flowchart illustrated inFIG. 12 , many other methods of operating theexample seat 128, 130 (or an accessory) and/or theexample stroller frame 102 may alternatively be used. For example, the order of execution of the blocks may be changed, and/or some of the blocks described may be changed, eliminated, or combined. - The
example process 1200 ofFIG. 12 includes positioning the seat or accessory relative to a receiver on a stroller frame (block 1202). For example, a user can position theseat 128 over one of themount receivers frame 102 such that theseat mount 200 of theseat 128 is substantially aligned over an opening orcavity 310 of the one of themount receivers - The
example process 1200 includes removably coupling the seat or the accessory to the receiver (block 1204). For example, the user can insert theseat mount 200 of theseat 128 in one of themount receivers seat mount 200 engages the one of themount receivers locks coupler 410 of theseat mount 200 engage with the openings ornotches 456 of the one of themount receivers seat 128 to theframe 102. - The
example process 1200 includes a decision whether to remove the seat or accessory from the stroller frame (block 1206). For example, the user may decide to remove the seat or accessory from the frame because the stroller is no longer being used and the user wishes to fold stroller. Or the user may wish to replace the seat or accessory with a different type of seat or accessory. For example, the user may wish to replace an upright seat for a toddler with a bassinet to accommodate an infant. - If a decision is made not to remove a seat or accessory from the stroller frame (block 1206), the
example process 1200 continues atblock 1214, as disclosed below. However, if a decision is made to remove the seat or accessory from the stroller frame (block 1206), theexample process 1200 includes unlocking a handle on the seat or accessory (block 1208). For example, the user may move the backrest arm(s) 203 of theseat 128 toward thenapper bar 202 such that thebackrest portion 133 of theseat 128 folds toward thesupport portion 135 of theseat 128. As the user moves thebackrest arms 203 and, in some examples, thenapper bar 202 to fold theseat 128, the cam(s) 468 of the seat connection hub(s) 208 of theseat 128 move away from thesecond end 466 of respective lock pin(s) 460, which releases thefirst end 462 of the spring-loaded lock pin(s) 460 from the pocket(s) 464 of therelease handle 414. The release of the lock pin(s) 460 from the pocket(s) 464 of therelease handle 414 via the rotation of theseat connection hub 208 enables a user to pull therelease handle 414. - The
example process 1200 includes releasing a handle on the seat or accessory to unlock the seat or accessory from the receiver (block 1210). For example, the user may pull the release handle 414 outward relative to themount receiver seat mount 200 is coupled, which causes thesecond plate 426 to slide with therelease handle 414 and rotate theactuator 430 of theseat mount 200. Rotation of theactuator 430 causes thelocks notches 456 of themount receiver - When unlocked, the user can lift the seat or accessory out of the receiver (block 1212). For example, when the
seat 128 or accessory is unlocked from themount receiver release handle 414 and the resulting disengagement of theseat mount 200 from themount receiver locks mount receiver - The
example process 1200 includes a decision whether to attach another seat or accessory to the stroller frame (block 1214). For example, the user may wish to replace the seat (e.g., an upright seat) or accessory removed from the frame with another type of seat (e.g., a bassinet) or accessory. Also, if the user previously in theexample process 1200 decided not to remove the seat or accessory from the stroller frame (e.g., block 1206), the decision atblock 1214 would be whether to attach another seat or accessory to the frame via a different receiver than the receiver to which the seat or accessory is coupled. If the user wishes to attach another seat or accessory to the stroller frame (block 1214), the example process 1100 returns to the user positioning a seat or accessory over a receiver on the stroller frame to removably couple the seat or accessory to the frame (blocks 1202, 1204). The type of seat or accessory can differ from the seat or accessory currently attached to the stroller frame to provide for combinations such as one seat and one accessory, one upright seat and one bassinet, etc. Also, the orientation of the seat or accessory can differ from the seat or accessory currently attached to the stroller frame to include, for example, one forward-facing seat and one rearward-facing seat. - If the user does not wish to attach another seat or accessory to the stroller frame (block 1214), the
example process 1200 ends. - From the foregoing, it will be appreciated that methods and apparatus have been disclosed to provide for removable coupling of one or more seats or accessories to a stroller frame. Disclosed example stroller frames provide for attachment of the one or more seats and/or accessories to the frame in different combinations with respect to type of seat (e.g., upright seat, bassinet), placement of the seat relative to the stroller frame (e.g., left, middle, or right side), and orientation (e.g., forward- or rearward-facing or sideways) without requiring the user to adjust the stroller frame or consider factors such as stability of the frame. Rather, the user attaches the one or more seats or accessories to the frame without modifying the frame and/or the seats or accessories, which provides for flexibility in coupling different seats and/or accessories to the stroller frame.
- In disclosed examples, a seat mount of a seat or accessory is inserted into a receiver on the frame to couple the seat or accessory to the frame. In some disclosed examples, the seat mount includes locks that are engage with openings in the receiver to couple the seat mount to the receiver. In some such examples, the locks are operated via rotation of an actuator, which is activated by extension or retraction of a handle. In such examples, the rotation of the actuator causes the locks to extend and retract to mount the seat to the frame. The control of the locks via the handle of the seat mount increases user control over the coupling of the seat to the stroller frame and reduces the number of movable parts on the stroller frame, thereby simplifying the attachment of the seat and the frame while providing for secure coupling of the seat to the frame.
- Further, in some disclosed examples, removal of the seat from the stroller via the slidable handle is controlled by a lock pin, which prevents unintended movement of the handle. Instead, a user selectively adjusts a positon of the backrest arm(s) and/or napper bar of the seat (e.g., to substantially fold the seat), which releases the lock pin disposed between a rotatable joint of the seat and the seat mount release handle. Thus, examples disclosed herein provide for secure coupling of a seat or accessory to the stroller to protect stroller occupants while also facilitating ease of access for the user (e.g., a caregiver).
- Although certain example methods, apparatus and articles of manufacture have been disclosed herein, the scope of coverage of this patent is not limited thereto. On the contrary, this patent covers all methods, apparatus and articles of manufacture fairly falling within the scope of the claims of this patent.
