Description

BACKGROUND OF THE INVENTION

Field of the Disclosure

The present invention relates in general, to wheeled devices for carrying car seats.

Description of the Related Art

In the United States, the National Highway Traffic Safety Administration sets guidelines for the use of car seats and all states have their own laws governing the use of car seats. For example. Texas requires that children under 8 years old and less than 4 feet 9 inches tall be in a car seat or a booster seat. Children under 1 year old and/or less than 35 lbs should be placed in a rear facing car seat when riding in an automobile. California law also requires that children under 8 years old and less than 4 feet 9 inches tall be in a car seat or a booster seat. Children under 2 years old that are less than 40 pounds or 40 inches tall must be restrained in a rear facing car seat.

Rear facing car seats typically can be used to carry an infant and the rear facing car seat can be engaged with a detachable car seat base that is properly tethered in a vehicle. Using such a system allows the parent to strap their small child in the rear facing car seat, carry the rear facing car seat to the car and engage the rear facing car seat with the detachable car seat base. Once the rear facing car seat is engaged with the detachable car seat base the rear facing car seat may not be disengaged without toggling, a release mechanism.

The car seat industry is always seeking improvements to car seats and the different ways in which car seats are transported when not in a motor vehicle.

DETAILED DESCRIPTION

The following is generally directed to a rolling car seat carrier that is suited to receive and engage a child car seat, e.g., a rear-facing infant car seat. Embodiments are directed to a car seat carrier having a carrier body that is configured to receive and lockably engage an infant car seat therein. The carrier body is further configured to retain the infant car seat in engagement with the carrier body until a release handle on the infant car seal is toggle by a user. As such, the infant car seat is securely attached to the carrier body. The carrier body can include two front wheels directly attached to the carrier body. The two front wheels can rotate around a first axis and swivel around a second axis. The carrier body can also include two rear wheels directly attached to the carrier body. The two rear wheels can rotate around a first axis. A pivoting and telescoping handle can be attached to the front of the carrier body near the front wheels. A user can grasp a handgrip on the pivoting/telescoping handle with one hand and push the car seat carrier or pull the car seat carrier. Accordingly, the car seat carrier is human powered and not powered by a motor, an engine, or other non-human power source.

The pivoting/telescoping handle is configured to be move between various positions. For example, the pivoting/telescoping handle can be moved to a first stowage position in which the pivoting/telescoping handle is in a collapsed configuration and folded back across the carrier body of the car seat carrier. Further, the pivoting/telescoping handle can be moved to a second stowage position in which the pivoting/telescoping handle is in the collapsed configuration and rotated away from the carrier body so that the hand grip on the pivoting/telescoping handle is in a position furthest from the carrier body. The pivoting/telescoping handle can also be moved to a from push/pull position in which the pivoting/telescoping handle is in an extended configuration and rotated so that the pivoting/telescoping handle, or the handgrip, is forward of the axis around which the pivoting/telescoping handle rotates, in this front push/pull position, a user can use the pivoting/telescoping handle to push the car seat carrier or pull the car seat carrier. In either case, an infant car seat, and an infant securely placed in the infant car seat, would be facing the user.

The pivoting/telescoping handle can be further moved to a rear push position in which the pivoting/telescoping handle is in the extended configuration and rotated so the pivoting/telescoping handle, or handgrip, is behind the axis about which the pivoting/telescoping handle rotates, in this position, a user can push the car seat carrier with the infant car seat engaged with the car seat carrier, and an infant therein, facing the direction in which the car seat carrier is pushed, i.e., away from the user. Finally, the pivoting/telescoping can be moved to a broadcast position in which the handle, in either the collapsed configuration or extended configuration, is rotated to a vertical position or slightly aft so that the handgrip is behind the axis of rotation. In the broadcast position, a portable electronic device, e.g., a smartphone, that is securely held within a bracket on the pivoting/telescoping handle can be located in a position to allow an infant within the infant car seat to listen to and watch content that is being broadcast by the portable electronic device.

The car seat carrier is configured to have a foot print that is nearly identical in area to the footprint of the infant car seat that can be installed therein. As such, the car seat carrier takes up relatively little floor space and is very easy to maneuver in crowded spaces, in narrow spaces, around closely placed objects, etc. Further, the car seat carrier supports the infant car seat in a manner that is relatively low to the surface on which the car seat carrier is used. This provides a relatively low center of gravity that makes is difficult to tip over the car seat carrier. Further, this allows a user to sit in a chair adjacent to the car seat carrier, e.g., at a doctor's office, and easily see and interact with the infant that is securely placed within the infant car seat attached to the car seat carrier.

FIG. 1 through FIG. 14 illustrate a car seat carrier that is generally designated 100. As shown, the car seat carrier 100 can include a carrier body 102. The carrier body 102 can be sized and shaped to receive and lockably engage a complementary shaped infant car seat, as described in detail below. In particular, the carrier body 102 can include a molded shell that can be substantially symmetrical about a central longitudinal axis 104. In one aspect, the carrier body 102 can be a one-piece molded shell. The carrier body 102 may be molded from a polymer material. In particular, the carrier body 102 may be made from a lightweight, durable plastic material. For example, the carrier body 102 may be made from polypropylene, such as impact grade polypropylene or impact copolymer polypropylene. In another aspect the carrier body 102 may be made from nylon, in still another aspect, the carrier body 102 may be made from a metal or a metal alloy. For example, the carrier body 102 may be stamped from sheet steel or aluminum. In one particular aspect, the carrier body 102 can be a detachable car seat base that is configured to receive and engage a car seat, described below.

In a particular aspect, the entire car seat carrier 100 can have a weight, W_CSC, and W_CSC can be less than or equal to 20 pounds.

The first cavity 122 and the second cavity 124 can extend from the rear end 108 of the carrier body 102 to the transverse wall 114 of the carrier body 102. Further, the cavities 122, 124 can be sized and shaped to receive a complementary shaped portion of a body of an infant car seat. A curved platform 126 can extend between the first inner side wall 118 and the second inner side wall 120 and between the rear end 108 of the carrier body 102 and the transverse wall 114. In a particular aspect, the first cavity 122, the second cavity 124, and the curved platform 126 are configured to receive and lockably engage a complementary shaped infant car seat, as shown in greater detail in FIG. 16.

As illustrated in FIG. 3, the carrier body 102 can further include a first rear locking notch 128 formed in the first outer side wall 110 adjacent to the first cavity 122. Moreover, the carrier body 102 can include a second rear locking notch 130 formed in the second outer side wall 112 adjacent to the second cavity 124. The rear locking notches 128, 130 are configured to receive retractable securing projections on an infant car seat as illustrated in FIG. 15.

The carrier body 102 can further include a first front guide 132 that can extend in an upward direction from an upper surface 134 of the carrier body 102. The carrier body 102 can also include a second from guide 136 extending from the upper surface 134 of the carrier body 102 opposite from the first front guide 132 across the longitudinal axis 104. A first flout slot 138 may be formed in the upper surface 134 of the carrier body 102 adjacent to the first front guide 132. A second front slot 140 may be formed in the upper surface 134 of the carrier body 102 adjacent to the second front guide 136 and opposite the first front slot 138.

A first hook 142 may extend through the first front slot 138 so that the head of the first hook 142 faces the front end 106 of the carrier body 102. A second hook 144 may extend through the second front slot 140 so that the head of the second hook 144 faces the front end 106 of the carrier body 102. The first hook 142 and the second hock 144 on the carrier body 102 of the car seat carrier 100 are configured to engage attachment points on the underside of an infant car seat. Accordingly, the first hook 142, the second hook 144, the first rear locking notch 128, and the second rear locking notch 130 work in concert to engage and lock an infant car seat to the car seat carrier 100, as shown in FIG. 16 through FIG. 22.

Referring now to FIG. 4, the canter body 102 of the car seat carrier 100 can further include a bottom plate 150 that can cover and enclose the underside of the carrier body of the car seat carrier 100. The bottom plate 150 can include a rear portion 152 that extends from the rear end 108 of the carrier body 102 to a point located between the midpoint 116 of the carrier body 102 and the front end 106 of the carrier body 102. The bottom plate 150 can also include a front portion 154 that can extend from the front end 106 of the carrier body 102 to a location between the midpoint 116 of the carrier body 102 and the rear end 108 of the carrier body 102. It can be appreciated that the bottom plate 150 may be a single continuous bottom plate in which the rear portion 152 and the front, portion 154 are integrally formed with each other. Further, the bottom plate 150 may be attached to the carrier body 102 via a plurality of threaded fasteners 156, e.g., screws.

FIG. 4 further indicates that the car seat carrier 100 can include a first rear axle support 160 that can extend in a generally downward direction from the bottom plate 150, e.g., the rear portion 152 of the bottom plate 150. The first rear axle support 160 can be formed with a transverse axle bore 162. A second rear axle support 164 can also extend in a generally downward direction from the bottom plate 150. e.g., the rear portion 152 of the bottom plate 150. The second rear axle support 164 can be opposite from the first rear axle support 160 across the longitudinal axis 104. The second rear axle support 164 can also be formed with a transverse axle bore 166.

In another aspect, the tire 196 may be made from robber and filled with air. In another aspect, the tire 206 may be made from rubber and filled with air.

Returning to FIG. 4, the car seat carrier 100 can further include a first front wheel assembly 210 installed in the bottom plate 150 of the carrier body 102, e.g., the second portion 154 of the bottom plate 150. In particular, the first front wheel assembly 210 can include a threaded stem 212 that extends through a bore 214 formed in the bottom plate 150 near the front end 106 of the carrier body 102. A threaded nut 216 can engage the threaded stem 202 and hold the first front wheel assembly 200 firmly in place.

The car seat carrier 100 can also include a second front wheel assembly 220 installed in the bottom plate 150 of the carrier body 102, e.g., the second portion 154 of the bottom plate 150. In particular, the second front wheel assembly 220 can include a threaded stem 222 that can extend through a bore 224 formed in the bottom plate 150 near the front end 106 of the carrier body 102. A threaded nut 226 can engage the threaded stem 222 and hold the second front wheel assembly 220 firmly in place. The front wheel assemblies 210, 220 can be swiveled wheels assemblies e.g., wheel assemblies that rotate about two axes and provide steering.

FIG. 1 shows that the first front wheel assembly 210 can include a base plate 230 from which the threaded stem 212 can extend up into carrier body 102 through the bottom plate 150. A wheel support frame 232 can be coupled to the base plate 230 via a bearing assembly and an internal post (not shown). The wheel support frame 232 can rotate three-hundred and sixty degrees (360°) relative to the base plate 230 around an axis centered on the threaded stem 202. Further, the wheel support frame 232 can rotate around the axis centered on the threaded stem 202 three-hundred and sixty degases (360°) relative to the carrier body 102.

The first front wheel assembly 210 also includes an axle 234 mounted in the wheel support frame 232. The axle 234 can include an at least partially threaded bolt held in place within the wheel support frame 232 by a threaded nut 226. A wheel 238 can be mounted on the axle 234 and rotate thereon. Further, a tire 240 can be mounted on the wheel 238. In a particular aspect, the wheel 238 may be made from a polymer material. In particular, the wheel 238 may be made from polypropylene, such as impact grade polypropylene or impact copolymer polypropylene. In another aspect, the wheel 238 may be made from nylon. The tire 240 may also be made from a polymer material. For example, the tire 240 may be a solid tire made from polymer foam material. Further, the tire 196 may polyurethane foam material, e.g., a closed cell polyurethane foam material. In another aspect the tire 240 may be made from rubber and filled with air in still another aspect, the tire 240 may be a solid polymer tire. e.g., a solid polyurethane tire or a solid rubber tire. Since the wheel 238 is mounted on the axle 234 of the wheel support frame 232, the wheel 238 and the tire 240 may also rotate three-hundred and sixty degrees (360°) relative to the carrier body 102 with the first front wheel assembly 210.

FIG. 4 indicates that the first front wheel assembly 210 may also include a wheel lock 242 that may be toggled between an “ON” position and an “OFF” position. When the wheel lock 242 is in the “ON” position, the wheel 238 and the tire 240 may not easily rotate within the first front wheel assembly 210 on the axle 234. When the wheel lock 242 is in the “OFF” position, the wheel 238 and the tire 240 may freely rotate within the first front wheel assembly 210 on the axle 234. Accordingly, a user can lock the wheel 238 of the first wheel assembly 210 in order to prevent the car seat carrier 100 from freely moving relative to a surface on which the car seat carrier 100 is placed.

FIG. 2 show that the second front wheel assembly 220 can include a base plate 250 from which the threaded stem 222 can extend up into carrier body 102 through the bottom plate 150. A wheel support frame 252 can be coupled to the base plate 250 via a bearing assembly and an internal post (not shown). The wheel support frame 252 can rotate three-hundred and sixty degrees (360°) relative to the base plate 250 around an axis centered on the threaded stem 222. Further, the wheel support frame 252 can rotate around the axis centered on the threaded stem 222 three-hundred and sixty degrees (360°) relative to the carrier body 102.

The second front wheel assembly 220 also includes an axle 254 mounted in the wheel support frame 252. The axle 254 can be an at least partially threaded bolt held in place within the wheel support frame 252 by a threaded nut 256. A wheel 258 can be mounted on the axle 254 and rotate thereon. Further, a tire 260 can be mounted on the first front wheel 258. In a particular aspect, the wheel 258 may be made from a polymer material. In particular, the wheel 258 may be made from polypropylene, such as impact grade polypropylene or impact copolymer polypropylene. In another aspect, the wheel 258 may be made from nylon. The tire 260 may also be made from a polymer material. For example, the tire 260 may be a solid tire made from a polymer foam material. Further, the tire 196 may polyurethane foam material, e.g., a closed cell polyurethane foam material. In another aspect, the tire 260 may be made from rubber and filled with air. In still another aspect, the tire 260 may be a solid polymer tire, e.g., a solid polyurethane tire or a solid rubber tire. Since the wheel 258 is mounted on the axle 254 of the wheel support frame 252, the wheel 258 and the tire 260 may also rotate three-hundred and sixty degrees (360°) relative to the carrier body 102 with the second front wheel assembly 220.

FIG. 4 indicates that the second front wheel assembly 220 may also include a wheel lock 262 that may be toggled between an “ON” position and an “OFF” position. When the wheel lock 262 is in the “ON” position, the wheel 258 and the tire 260 may not easily rotate within the second front wheel assembly 220 on the axle 254. When the wheel lock 262 is in the “OFF” position, the wheel 258 and the tire 260 may freely rotate within the second front wheel assembly 220 on the axle 254. Accordingly, a user can lock the wheel 258 of the second front wheel assembly 220 in order to prevent the car seat carrier 100 from freely moving relative to a surface on which the car seat carrier 100 is placed. It can be appreciated that the wheels 238, 258 of both front wheel assemblies 210, 220 may be locked at the same time to prevent the car seat carrier 100 from rolling on a surface.

It can be appreciated that the front wheels 238, 258 and from tires 240, 260 can swivel around the stems 232, 222 in unison with each other, but also independent from each other. Further, the front wheels 238, 258 and front tires 240, 260 can swivel around the stems 212, 222 in response to steering inputs provided to the front 106 of the carrier body 102 via handle affixed thereto as described in detail below. However, the front wheels assemblies 210, 220 are not directly connected to the handle.

As shown in FIG. 2, the rear wheel assemblies 180, 184 can have a diameter, D_R. The front wheel assemblies 210, 220 can have a diameter, D_F. Further, the car seat carrier 100 can have a first wheelbase when it is pulled, WB_PULL, and a second wheelbase when if is pushed, WB_PUSH, as illustrated in FIG. 13. WB_PULL can be measured from the center of the rear wheel assemblies 180, 184 to the center of the axles 234, 254 of the front wheel assemblies 210, 220 when the front wheel assemblies 210, 220 are in position for the car seat carrier 100 to be pulled by a user, as shown in FIG. 2.

With the configuration of structure described herein the car seat carrier according to any of the aspects, can provide a car seat carrier that is relatively low to the ground with a relatively low center of gravity. This can provide a car seat carrier that is difficult to tip over. Further, this can provide a car seat carrier that a user can see into and keep an eye on an infant wherein while sitting in a chair, couch, or other low seating element. Moreover, while seated, a user can gently roll the car seat carrier back and forth to provide soothing motion for an infant placed in an infant car seat engaged with the car seat carrier. Additionally, the configuration of structure described herein, can provide a car seat carrier that is relatively compact and can fit in areas that, traditional strollers, or car seat carriers, cannot fit. For example, the car seat carrier according to one or more aspects herein can fit in the aisle on a bus, a train, an airplane, or other narrow aisle. Further, the car seat earlier can fit on a subway car without taking up much more space than a car seat that may be carried by a user. In another aspect, the car seat carrier can fit into the overhead compartment on most passenger airplanes. The car seat carrier according to one or more embodiments described herein can provide a car seat carrier that is human powered and non-motorized. Further, the placement of the wheels and handle results in a car seat carrier that is very agile, nimble, and relatively easy to maneuver around obstacles and in locations that may be difficult to maneuver a typical stroller. For example, the car seat carrier is relatively easy to push or pull on a sidewalk, around light posts, around mailboxes, around clothing racks in a store, inside a house, or at other locations that are filled with obstacles that hinder the use of a conventional stroller. Further, the bi-directional usability of the car beat carrier provides a car seat carrier that can be easily pushed or pulled. In addition, the placement of the wheel assemblies relative to each other on the carrier body of the car seat carrier provides a car seat carrier that can quickly be rotated from the push position to the pull position. As such, if a user is pushing his child in an infant car seat lockably installed within the car seat carrier and the sunlight is shining in the child's face, the user can quickly rotate the car seat carrier, and the infant car seat therein, one-hundred and eighty degrees (180°) from the push position to the pull position so that the sunlight is no longer shining in the child's face.

Additionally the car seat carrier, according to one or more aspects described herein, provides a relatively easy way to transport an infant car seat to an automobile or other vehicle. At the vehicle, the user can disengage the infant car seat from the car seat carrier and engage the infant car seat with a detachable car seat base properly installed within the vehicle. To stow the car seat carrier in the vehicle trunk, or other space, the user can simply move the pivoting/telescoping handle to the collapsed configuration and rotate the pivoting/telescoping handle to the first stowage position, i.e., so that the pivoting/telescoping handle is folded back over the top of the carrier body. The user may then easily lift the car seat carrier and place it in the trunk of the vehicle for storage. To prevent the car seat carrier from rolling, around within the truck of the vehicle, the front wheel assemblies can be locked. When the user arrives at his or her destination, he or she can easily lift the car seat carrier from the trunk of the vehicle, rotate and extend the handle to the push/pull position, release the infant car seat from the detachable car seat base in the vehicle, and engage the infant car seat with the car seat carrier. Using the car seat carrier is quite easy. There is no need to collapse or expand a mechanically complex framework that is typically associated with a folding stroller. Many folks will leave their conventional folding stroller at home because it can be relatively difficult to fold and unfold. Also a conventional folding stroller can be relatively bulky, heavy, and difficult for some smaller users to pick up and easily place the folded stroller in the trunk of a vehicle.

Moreover, since the car seat carrier is specifically designed to receive the infant car seat in a manner similar to that of the detachable car seat base, the infant car seat is securely locked within the car seat carrier and the risk of the infant car seat from falling out of the car seat carrier is minimized. Further, using the car seat carrier, according to one or more of the aspects described herein, in conjunction with an infant car seat carrier provides a very safe way to transport an infant child that is properly buckled in the infant car seat. Most infant car seats are crash tested and are designed to withstand car crashes white protecting the infant therein, if a user is pushing bis or her child around the neighborhood, in a parking lot, or other location, and the infant car seat carrier assembly is impacted by a motor vehicle, a bicycle, or other vehicle, the child is less likely to get injured when compared with a conventional stroller or conventional wagon which is not as rigorously tested as a car seat and is not designed to survive an automobile accident. It can be appreciated that the car seat carrier can be integrally formed with the infant car seat.

Many different aspects and embodiments are possible. Some of those aspects and embodiments are described herein. After reading this specification, skilled artisans will appreciate that those aspects and embodiments are only illustrative and do not limit the scope of the present invention.
