CARRIER SUPPORT SYSTEM
A carrier system includes a carrier base that defines a carrier footprint. A first carrier support member extends from an outer side surface on the carrier base, and includes a first user engagement member that is located outside of the carrier footprint. A second carrier support member extends from the carrier base from a location on the carrier base that is opposite the outer side surface from the first carrier support member, and includes a second user engagement member. The engagement of the first user engagement member with a hand of a user and the engagement of the second user engagement member with a portion of an arm of the user that includes the hand provides for support of the carrier base with the hand located outside of the carrier footprint, which has been found to reduce arm strain and provide a more natural carrying position for the user.
The present disclosure relates generally to carrier systems, and more particularly to a support system for a carrier system.
Carrier systems are typically utilized to assist a user in lifting, supporting, and carrying a wide variety of things, and include child carrier systems such as child car seats for carrying children, grocery carrier systems such as grocery baskets for carrying groceries, luggage carrying systems such as suitcases and bags for carrying clothing, and/or other carrier systems known in the art. Conventional carrier systems include a carrier seat, carrier basket, or carrier container that include a handle system that may extend from opposite sides of the carrier seat or carrier basket or from a surface of the carrier container, and that handle system provides a handle that is located within a footprint of the carrier seat, carrier basket, or carrier container (i.e., within a perimeter of the carrier seat, carrier basket, or carrier container when the carrier seat, carrier basket, or carrier container is viewed from a top view in its normal use orientation). As is known in the art of such carrier systems, the use of such handle systems to support the carrier seat, carrier basket, or carrier container typically involves the user using the handle to lift and support the carrier system, and typically results in the carrier seat, carrier basket, or carrier container engaging the leg and/or hip of the user when the user is standing or walking. Such engagement of the carrier seat, carrier basket, or carrier container with the leg and/or hip of the user can be annoying, painful, and in some cases damaging. Some solutions to this issue involve the user holding the carrier system out and away from their body to prevent the engagement of the carrier seat, carrier basket, or carrier container with their leg and/or hip, or engaging the handle system with the “crook” of their arm (e.g. between the forearm and the bicep on the user's arm). However, such solutions cause the user to engage several muscles in their arm and shoulder in a manner that result in accelerated fatigue and sometimes muscle damage.
Accordingly, it would be desirable to provide an improved carrier support system.
SUMMARYAccording to one embodiment, a child support system includes a seat chassis that defines a seat channel; a child seat located in the seat channel; a first user engagement member that is coupled to a first side of the seat chassis, wherein the first user engagement member is located outside of a footprint of the seat chassis and is configured to engage a first hand of a user; and a second user engagement member that is coupled to a second side of the seat chassis and that is configured to engage a portion of a first arm of the user when the first hand of the user is engaging the first user engagement member.
As discussed above, the use of conventional support systems on conventional carrier systems involves the user using a handle that is provided within a footprint of the carrier base to lift and support the carrier system, and typically results in the carrier base engaging the leg and/or hip of the user when the user is standing or walking. Furthermore, conventional solutions to this issue involve the user attempting to hold the carrier system out and away from their body to prevent the engagement of the carrier base with their leg and/or hip, or engaging the handle system with the “crook” of their arm (e.g. between the forearm and the bicep on the user's arm). When the carrier system is held out and away from the body of a user, several muscles in the users' arm and shoulder are engaged such as, for example, the deltoid, the bicep, the rotator cuff, several muscles in the shoulder, the supraspinatus muscle, and others. Much of this muscle engagement involves contracting the muscles in an isotonic manner (i.e., where the tension remains unchanged while the length of the muscle changes (shortens or lengthens) in order to support the weight of the carrier system), and can result in fatigue and sometimes damage. For example, the engagement of the supraspinatus muscle to support the carrier system in this manner is necessary because the supraspinatus muscle is responsible for the first 15-30 degrees of movement of the arm away from the body, and it is notable because the supraspinatus muscle is one of the most frequently torn muscles in the body, as well as one of the smaller muscles in the body and thus more prone to fatigue than the other muscles engaged when supporting the carrier system in this manner. Carrying the carrier system using the “crook” of a users' arm can reduce the engagement of the supraspinatus muscle to remedy some of the issues discussed above, but introduces a flexed elbow and engaged bicep to provide support the carrier system, which puts added stresses on the labrum in the shoulder (another frequently torn muscle) and provides for an awkward carrying orientation for the user.
As described in detail below, carrier support systems and methods for supporting a carrier system have been discovered that remedy the deficiencies of the conventional systems discussed above. The systems and methods of the present disclosure provide a carrier system that includes a carrier base with a handle that is located outside of the footprint of the carrier base, along with an arm support that extends from a location on the carrier base that is opposite at least some of the carrier base from the handle. A user may engage the handle with their hand to lift and support the carrier system while engaging the arm support with their arm (the arm that includes the hand engaging the handle) to also support the carrier system, which allows the user to lift and support the carrier system while standing and walking while reducing the occurrence of the carrier base engaging the leg and/or hip of the user. Furthermore, it is believed that the arm orientation that is enabled by the systems and methods of the present disclosure when lifting and supporting a carrier system produces less stress on the muscles in the arm and shoulder of the user relative to conventional systems and methods, particularly with regard the supraspinatus muscle. While in the embodiments discussed below, the carrier system is illustrated and described as a child carrier system, the teachings of the present disclosure will be beneficial for any of a variety of carrier systems including the grocery carrier systems and the luggage carrier systems discussed above, and/or any other carrier systems known in the art.

In yet other embodiments, the first carrier support member 108 may be attachable to and detachable from the carrier base 102 by the user via a variety of quick-attach and quick-release couplings known in the art. As such, a user may be enabled to attach the first carrier support member 108 to the side surface 106c of the carrier base 102 when the user wishes to perform the method 300 discussed below, and may detach the first carrier support member 108 from the side surface 106c of the carrier base 102 when the user is no longer performing the method 300 discussed below. In
In the illustrated embodiment, the first carrier support member 108 also includes a third user engagement member 108b that is positioned adjacent the first user engagement member 108a and that defines an arm channel 108c that is spaced apart from the first user engagement member 108a to allow a user to grasp the first user engagement member 108a with a hand and engage the third user engagement member 108 with an arm that includes that hand by placing that arm in the arm channel 108c, as discussed in further detail below. The third user engagement member 108b may include any of a variety of padding, cushioning, or other engagement features known in the art on its inner surface that is immediately adjacent the arm channel 108c such that those padding and/or cushioning features engage the arm of the user when that arm is located in the arm channel 108c. However, in other non-illustrated embodiments, the third user engagement member 108b may be omitted from the carrier system 100.
A second carrier support member 110 extends from the side surface 106d of the carrier base 102 and includes a second user engagement member 110a that, as discussed below, provides for supporting the chassis base 102 when the chassis base 102 is lifted and supported using the first user engagement member 108a. In some embodiments, the second carrier support member 110 is integral to the carrier base 102 as a molded portion of the carrier base 102 that extends from the side surface 106d. In other embodiments, the second carrier support member 110 is attached to the carrier base 102 via an attachment coupling on the carrier base 102 that may accept a variety of coupling members such as screws, clips, and/or other coupling members known in the art. In yet other embodiments, the second carrier support member 110 may be attachable to and detachable from the carrier base 102 by the user via a variety of quick-attach and quick-release couplings known in the art. As such, a user may be enabled to attach the second carrier support member 110 to the side surface 106d of the carrier base 102 when the user wishes to perform the method 300 discussed below, and may detach the second carrier support member 110 from the side surface 106d of the carrier base 102 when the user is no longer performing the method 300 discussed below.
In the embodiments illustrated in
The second user engagement member 110a defines an arm channel 110b that, in the illustrated embodiment, is located on a distal end of the second carrier support member 110 (opposite the end of the second carrier support member 110 that is connected to the side surface 106d) and that is configured to allow a user to engage the second user engagement member 110a with an arm when the user is grasping the first user engagement member 108a with their hand (and optionally has that arm engaging the third user engagement member 108b) by placing that arm in the arm channel 110b, as discussed in further detail below. However, in other embodiments, only a few of which are discussed below, the second user engagement member 110a may be provided at some point along the length of the second carrier support member 110 rather than on its distal end.

The method 300 begins at block 302 where the first user engagement member is engaged with a hand. In an embodiment, the user 400 may engage the first user engagement member 108a by grasping the first user engagement member 108a with their hand 406. As discussed above, the first user engagement member 108a may be moveable relative to the carrier base 102, and thus in some embodiments the user 400 may move the first user engagement member 108a relative to the carrier base 102 and into an orientation desired by the user prior to grasping the first user engagement member 108a (and subsequent to securing the first user engagement member 1089a in that orientation in some embodiments), or the user 400 may move the first user engagement member 108a relative to the carrier base 102 and into an orientation desired by the user subsequent to grasping the first user engagement member 108a. In embodiments in which the third user engagement member 108b is provided (e.g., as illustrated), at block 302 the user 400 may move the hand 406 and second portion of the arm 404 through the arm channel 108c defined by the third user engagement member 108b in order to grasp the first user engagement member 108a, and as a result the third user engagement member 108b will be engaged by the second portion 404 of the arm of the user 400.
The method 300 then proceeds to block 304 where the second user engagement member is engaged with a portion of an arm. In an embodiment, the user 400 may engage the second user engagement member 110a by positioning the first portion 402 of their arm in the arm channel 110b defined by the second user engagement member 110a. As discussed above, the second user engagement member 110a may be moveable relative to the carrier base 102, and thus in some embodiments the user 400 may move the second user engagement member 110a relative to the carrier base 102 and into an orientation desired by the user and that allows the first portion 402 of their arm to be positioned in the arm channel 110b and in engagement with the second user engagement member 110a. In some embodiments, the user 400 may move the hand 406, the second portion 404 of their arm, and the first portion 402 of their arm through the arm channel 110b defined by the second user engagement member 110a (and through the arm channel 108c defined by the third user engagement member 108b, when provided) in order to grasp the first user engagement member 108a, and as a result the second user engagement member 110a is engaged by the first portion 402 of the arm of the user 400 (as well as the third user engagement member 108b being engaged by the second portion 404 of the arm of the user 400, when provided).
The method 300 then proceeds to block 306 where a lifting force is provided on the first user engagement member to produce a support force on the second user engagement member. As illustrated in
Furthermore, the orientation of the arm of the user 400 when lifting and supporting the carrier system 100 as illustrated in
Thus, systems and methods have been described that provide a novel carrier system and method for supporting a carrier system that provide substantial benefits over conventional carrier systems and methods. The carrier systems and methods of the present disclosure utilize a handle extending from a first outer surface of the carrier base such that the handle is located outside of a footprint of the carrier chassis, along with a support member that extends from a second side of the carrier chassis and that is configured to engage an arm of a user when the hand on that arm is lifting the carrier chassis using the handle. A user lifting and supporting the carrier chassis using the systems and methods of the present disclosure will not engage their hip and/or leg with the carrier chassis when the user is holding the carrier system and/or walking with the carrier system, and may do so using an arm orientation that produces less stress on the muscles in the user's arm and shoulders than is experienced in conventional carrier systems, thus providing the user the ability to support the carrier system comfortably and without stress, fatigue, or injury.

In operation, the alternative carrier system 500 may be utilized according to the method 300 substantially as described above for the carrier system 100. In some embodiments, the user may utilize the hand 406 on their right arm to grasp the first user engagement member 108a while engaging the modified second user engagement member 502a with the second portion 404 on their right arm (as illustrated in
Furthermore, the alternative carrier system 500 also includes rotatable couplings 506a and 506b that are located between the first user engagement member 108a and the modified second carrier support member 502, as well as between the added user engagement member 504 and the modified second carrier support member 502. In some embodiments, the modified second carrier support member 502 may be utilized to lift and support the alternative carrier system 500 in a conventional manner. The rotatable couplings 506a and 506b may be utilized to allow the modified second carrier support member 502 to be rotated about an axis defined by the rotatable couplings 506a and 506b to, for example, move the modified second carrier support member 502 adjacent the front surface 106a or back surface 106b of the carrier base 102 (e.g., when positioning the alternative carrier system 500 in a car). Further still, the alternative carrier system 500 also includes extendable couplings 508a and 508b located between the first user engagement member 108a and the modified second carrier support member 502, as well as between the added user engagement member 504 and the modified second carrier support member 502.
