[0023] Conventional outdoor furniture, e.g., folding chairs, is intended to allow users to carry their own chairs. For example, a folding chair having a shoulder strap configuration allows users to carry a single chair to its destination but is limited in that it only allowsAttorney Docket No.: DV8-P001WO the user to carry a single chair on their back. It is common for beach goers or campers to have multiple people in their group, each needing a chair to sit in, but not all beach goers or campers are capable of lifting and carrying a chair on their back. Thus, beach goers or campers are burdened with a folding chair on their back, and several other chairs in their hands. Having one’s hands full carrying chairs results in negating the very convenience of the backpack strap chair.

[0024] Accordingly, the inventors have developed a connector device and a multiple chair carry system that allow one chair to be attached to another chair, which can be attached to an additional chair, so on and so forth. This connector device allows a single user to stack multiple chairs together so that the user can carry all of them utilizing just the carrying device (e.g., backpack straps or handles) already attached to the lead chair. Further, the connector device allows a user to also stack other types of outdoor furniture, such as a folding table or an umbrella, and carry them from the lead chair or other chairs in the multiple chair carry system.

[0025] FIG. 1A shows an example multiple chair carry system 100 that includes one or more connector devices 102 that connect multiple chairs 104 (e.g., 104-1, 104-2, 104-3), according to some embodiments. FIG. IB shows an example of a person carrying multiple chairs connected via the multiple chair carry system 100 in FIG. 1 A, according to some embodiments. A folding chair (e.g., chair 104-1) may include a shoulder strap (e.g., 106 in FIG. IB) or a carry handle. Chair 104-1 may be a lead chair that connects other chairs. A lead chair may be a term relative to the chair that connects to it directly or indirectly. Whereas a chair may connect to a lead chair, it may also act as a lead chair for another chair connected thereto. A first lead chair may be strapped to or carried by the user and bears weight of the other chairs (or folding table or umbrella).

[0026] A lead chair (e.g., 104-1) and another chair (e.g., chair 104-2) may be releasably connected in variously ways. For example, lead chair 104-1 may include a connector device 102 configured to releasably connect to a second folding chair (e.g., 104-2). When connected in this manner, the first folding chair (e.g., 104-1) functions as a lead chair and may be strapped to a user or carried by the user while bearing weight of the other folding chairs (e.g., 104-2, 104-3). In such configuration, multiple chairs connected via the connector devices (e.g., 102 in FIG. 1A) can be carried by a single user via a carryingAttorney Docket No.: DV8-P001WO device (e.g., a shoulder strap or a carry handle) of a lead chair. As shown in the example in FIG. IB, the user can carry the multiple stacked chairs using shoulder straps 106 from the lead chair. Carrying in this method allows the user’s hands to be available for carrying other items or to maintain balance.

[0027] FIGS. 2A and 2B respectively show a side view and a front view of an example connector device 200, according to some embodiments. In some embodiments, connector device 200 may implement the connector device in system 100 (FIG. 1), e.g., connector devices 102. Connector device 200 may include a first connector 202 and a second connector 204. Connector 202 may be connected to a first folding chair and connector 204 may be connected to a second chair, where connectors 202 and 204 are coupled together. In the example shown in FIGS. 2A-2B, connector 202 may be a strap configured to be attached to a first folding chair and connector 204 may be a hook configured to be attached to a second folding chair. This is further described with reference to FIGS. 3A-3B.

[0028] FIG. 3A shows an example stackable multi-chair system, in which multiple chairs are connected together using an example of the connector device shown in FIGS. 2A and 2B easier transport, according to some embodiments. Connector device 302 may use the connector device 200 shown in FIGS. 2A-2B. As shown, connector device 302 may include a connector 306 (e.g., a strap) and a connector 304 (e.g., a hook) that are connected together. In a non-limiting example, connector 306 may be attached to a chair (e.g., 300-2) using a section of nylon webbing that is sewn to the chair fabric 308-2 of chair 300-2 at one end. Possible methods for attaching the connector 306 to the chair may also include, for example: riveted or bolted to chair frame (e.g., fastener goes through the fabric and secures to the frame metal). In some embodiments, webbing is wrapped around the chair frame and secured to itself (by sewing, buckle, or Velcro). In some embodiments, webbing is secured to the frame or fabric with snaps or other semi-secure method.

[0029] Once the chairs are stackably connected, the carry handle of the lead chair takes the weight of the second chair behind it, and the second chair hangs by gravity. The second chair carry handle takes the weight of a third chair, the third chair carry handle takes the weight of the fourth chair, and so on. When the user arrives at the desiredAttorney Docket No.: DV8-P001WO location, he or she simply removes the shoulder straps and then disconnects the chairs from each other one by one.

[0030] The other end of connector 306 may be fixedly connected to connector 304 (e.g., a hook shaped apparatus). Connector 304 may be configured to connect to a carry handle 310 on another chair (e.g., a lead chair 300-1). As shown, the locations for hook / connector may be the center of the upper chair, either on the front or back of the chair.

[0031] FIG. 3B shows another example stackable multi-chair system in which multiple chairs are connected by a dual connection system, where connector devices 302-1 (including connectors 304-1 and 306-1) and 302-2 (including connectors 304-2 and 306- 2) are positioned to connect chairs 300-1 and 300-2 at two locations rather than a single location. Each of the connector devices 302-1 and 302-2 may have a structure similar to connector device 302 (FIG. 3A) and connect the two chairs (e g., 300-1, 300-2) in a similar manner. For example, connectors 304-1 and 306-1 (shown in FIG. 3B) are connected in a similar as connectors 304 and 306 are connected (shown in FIG. 3A). Connectors 304-2 and 306-2 (shown in FIG. 3B) may also be connected in a similar manner. Similarly, connectors 304-2 and 306-2 may each be attached to folding chair 300-2 in a similar manner as connector 306 is attached to chair 300-2 (shown in FIG. 3A).

[0032] Connectors 304-1 and 304-2 may also be configured to releasably connect to lead chair 300-1 in a similar manner as connector 304 is connected to chair 300-1 (shown in FIG. 3A). In such configuration, when lead folding chair 300-1 and folding chair 300-2 are connected by the connector devices 302-1 and 302-2 and carried by the user, both of these connector devices (instead of one connector device) bear weight of the second folding chair (e.g., 300-2). This prevents the second folding chair (e.g., 300-2) from dangling off the lead chair 300-1, and thus, improve the stability of the stackable multichair system.

[0033] In some examples, the connector devices may be positioned to connect to the lead chair at the sides (e.g., at frames), or left and right sides of a central handle bar, or two sides of the upper section of the lead chair. For example, connector devices 302-1 and 302-2 may be located at positions A and B, which are opposite locations about a verticalAttorney Docket No.: DV8-P001WO center line L of the lead folding chairs 300-1. In non-limiting examples, connectors 304-1 and 304-2 may be configured to be attached to a frame of the folding chair 300-1 (e.g., a top frame 308-1). In other non-limiting examples, connector devices 302-1 and 302-2 may be attached to chair 300-1 on side frames opposite each other with respect to the vertical center line L. For example, connector 304-1 may be configured to be attached to a left side frame of chair 300-1 and connector 304-2 may be configured to be attached to a right side frame of chair 300-1.

[0034] In FIGS. 3A and 3B, connector 304 (or 304-1 and 304-2) may be releasably attached to the folding chair 300-1 in various ways, such as hooking to a handle of the folding chair (e.g., 310 in FIG. 3A), or a frame of the folding chair (e.g., frame 308-1 shown in FIG. 3B). In other variations, FIG. 5A shows an example connector device 500 which may implement connector devices 102 (in FIG. 1A), for example. Connector device 500 may include a first connector (e.g., S-hook 502) and a second connector (e.g., strap 504) connected to the S-hook 502. S-hook 502 may be configured to connect to a chair via a webbing having a fabric loop 506. Strap 504 may be fixedly attached to another chair.

[0035] FIG. 5B shows an example connector device 520 which may implement connector devices 102 (in FIG. 1A). Connector device 520 may have a hook 524, where inner diameter of hook 524 is concentric to the diameter of the carry handle and / or the frame of the chair (e.g., 522) to which the connector device connects. In this example, connector 524 may be adjustable in inner diameter to fit the diameter of the frame (e.g. 522). The hook profile may be configured in such a way that accommodates multiple diameters. In some examples, the hook may be configured to have enough flex in the shape design to accommodate the carry handle sizing and / or the frame sizing of different chair types and manufacturers.

[0036] In other variations, the connector device which implements the connector devices 102 in system 100 (FIG. 1A) may also include a bendable Gear Tie on webbing into fabric loop or plastic receiver or frame from the second chair to the lead chair. The connector device may also include strap (self-securing with Velcro / snaps / other connector) to the carry handle of the chair. The connector device may also include a strap (self-securing with Velcro / snaps / other connector) to the frame of the lead chair. TheAttorney Docket No.: DV8-P001WO connector device may also include a buckle strap (buckles to itself, e.g., both male and female buckles are attached to the same strap) to the carry handle or frame of the lead chair, or buckle straps (for example: lead chair has a female buckle strap, and the second chair has a male buckle strap) where the buckle straps are sewn to fabric of the chairs or sewn to form a closed loop around the frames of both chairs.

[0037] FIGS. 6A-6B show an example connector device 600 may implement connector devices 102 in system 100 (FIG. 1A). Connector device 600 may having intentionally mated parts 604-1 and 604-2 and may connect folding chairs 608-1 and 608-2, such that the two chairs can be releasably connected when the mated parts are mated together. When the mated parts are disengaged, the two chairs can be disconnected.

[0038] In FIG. 6A, connector device 600 may include a first connector (e.g., male connector 604-1) and a second connector (e.g., female connector 604-2 for which inside is shown). Connectors 604-1, 604-2 can be mated to connect chairs 608-1 and 608-2. In some embodiments, the male connector 604-1 may optionally be connected to one end of a strap that is attached a first chair e.g., 608-1, and the female connector 604-2 may be fixedly attached (e.g., sewed) to a second chair (e.g., chair 608-2).

[0039] FIG. 6B shows details of the connector part shown in circle A in FIG. 6A, where the male connector 604-1 is secured into the female connector 604-2 with side release 610. As shown in FIG. 6B, the connector device 600 may be positioned in such a way that the male connector 604-1 is slidably inserted into the female connector 604-2 from top of the chair (shown in arrow). In this manner, with chair 608-2 being the lead chair, the connector device 600 may bear more weight from the second chair 608-1 without breaking or unbuckling.

[0040] In other variations, a connector device (e.g., 102 in FIG. 1A) may be structured in other ways. FIG. 3C shows a variation of a connector device for use with a multiple chair carry system, according to some embodiments. As shown, connector device 350 may include a handle 352 and a hook 356 extending from the handle 352, where the handle 352 is fixedly attached to the folding chair.
