The present invention relates generally to portable chairs, and more particularly relates to lightweight chairs of portable, collapsible type including one or more storage container thereon.
Folding and collapsible furniture, generally, is well known and has been used a long time. Popularity of the mini van, the sport utility vehicle and the recreational vehicle has resulted in increased demand for improved collapsible furniture and particularly collapsible portable furniture of the outdoor type which may be readily stowed in a vehicle and conveniently manually transported to a picnic area or the site of a spectator event, such as, for example, an outdoor concert, a sporting event, a golf tournament, or an air show, where the general rule is to bring your own seating accommodations. Accordingly, the general intent of folding furniture is ease of storage and portability, i.e., the furniture can be set-up for use and then folded down for transport and/or storage in a space of smaller volume than what the furniture occupies in its set-up condition. It also has been noted that it would be desirable to have the furniture fold down to fit within a space of minimum possible perimeter and/or volume, i.e., for purposes of shipping the furniture at a minimal rate when the shipping rate is based in part on the volume and perimeter of the package to be shipped.
Lightweight, portable seats and chairs of a type with which the present invention is concerned are enjoying increasing popularity for use in viewing sports activities, concerts and a wide variety of other outdoor activities such as camping, boating, hunting, fishing and the like, normally lacking adequate preexisting seating accommodations. As so used, it is desirable to have a container provided as part of the chair: firstly, to provide a means to store extra items—such as, a wallet or purse, a phone or tablet, car keys, extra or excess clothing, snacks, sunscreen or the like; and secondly, as a way to reduce the number of objects the user needs to carry in her hands.
Folding chairs with storage containers are generally known in the art. However, it is desirable to be able to dose the container to secure and protect the items contained therein, thereby providing extra security from theft (e.g., at the beach or a park where the user may occasionally stray away from the chair). Prior art means have used variations of a flap that folds over the open top of the container. Such a flap is traditionally secured to the container using multiple connection spots and means, such as, zippers, hook-and-loop fastening means, buckle and clasp arrangements, buttons, snaps, and the like. However, each of these prior art means has drawbacks, mostly in connection with the ease and speed with which the user can gain access to the interior of the container and then be able to reclose and secure the container.
It is also desirable to have means to easily transport a folded chair, such as by using straps, so that the chair can be carried while keeping the user's hands free for carrying other objects. Preferably, such straps would be backpack straps so that the folded chair can be carried on the user's back, like a backpack, freeing up the user's hands to carry other objects. Optimally, the folded condition of the chair and the location of the straps when the chair is folded, do not interfere with the container. In some prior art designs, the container is not easily usable when the chair is folded. Additionally, such chairs may not have convenient straps for transporting the chair, and as a result, it is easy to lose items from within the container when the chair is folded and/or carried.
In view of the foregoing, there is a need for a lightweight, portable chair that can be easily collapsed into a small bundle for transport and storage, and as easily set-up for use as a seat. There is also a need for such a chair that include a storage container with means for closing the container to secure items stored therein that is easy to close and access.
Accordingly, it is the general aim of the present invention to provide an improved, lightweight, portable, and collapsible chair that includes a closeable storage container that overcomes the problems and drawbacks associated with prior art folding chair with storage containers, and therefore significantly improves the utility of such chairs in the set-up condition and the folded condition for use and transport.
In accordance with embodiments of the present invention, a collapsible and portable chair includes a storage container formed in or mounted on the back-side of the backrest of the chair. Such a storage container can be used to secure and protect the items contained therein, thereby providing extra security from theft (e.g., at the beach or a park where the user may occasionally stray away from the chair). The storage container can be used to store a variety of items a user may bring with them, such as, a wallet or purse, a phone or tablet, car keys, extra or excess clothing, snacks, sunscreen or the like.
In a first aspect of the present invention, the container is formed on the back-side of the chair's back-rest by a web of fabric sewn to the backrest panel, enclosed on the bottom and both sides, but open on the top edge to provide easy access to the interior of the container. In an alternate embodiment, the container can be fully formed and thereafter attached to the backrest. In still another embodiment, the fully formed container could be removably attached to the backrest of the chair so that the user may use the container as attached to the chair, or separate from the chair, as desired and convenient.
In embodiments of the present invention, the open top end of the container can be closed using a cinching means. For example, a single rope anchored on each side of the container can be provided and fed through openings or grommets in the container fabric in an alternating threaded fashion, whereby the center of the rope can be pulled in a center portion of the container to tighten and gather the fabric material around the open top end to close the opening. Alternatively, two ropes can be used - more particularly, a left rope and a right rope, each anchored on a respective side of the container and fed through openings or grommets in the container fabric to meet in a middle portion of the container, whereby, again, pulling on the ropes will gather and cinch the opening of the container closed. To open the container, the rope can be relaxed and the fabric along the opening of the container can be pulled open so as to gain access to the interior of the container and objects contained therein.
A sleeve can be provided for essentially locking the container closed. That is, the sleeve is included on the slack of the rope or ropes at the middle of the container. When the rope is pulled to dose the opening, the length of rope in the middle relative to the fabric of the container increases. The sleeve can be slid toward the container fabric and positioned to hold the rope (and the slack thereof) in place relative to the container fabric so that the rope cannot relax and permit the container to open, especially when the are items in the container and/or the folded chair is being carried. To open the container, the sleeve can be pulled away from the fabric so that the fabric can be relaxed relative to the pull rope(s). Accordingly, the present invention provides a container that is easy to close, yet equally easy to gain access to the interior of the container without needing to fidget with tedious fasteners as known in the art and multiple such fasteners.
In another aspect of the present invention, the chair includes straps for easy transport. For example, the straps can be wrapped around the side of the folded chair away from the container and worn over the user's shoulders like a backpack. As so worn, the chair lies on the user's back and the container projects outwardly away from the user, much like standard backpack designs. Embodiments of this type of chair are described and shown in Applicant's co-pending U.S. patent application Ser. No. 15/975,339, filed May 9, 2018, and entitled “Collapsible and Portable Chair,” the disclosure of which is incorporated by reference herein in its entirety. Therefore, a chair and container in accordance with the present invention provides a way to reduce the number of objects the user needs to carry in her hands, or at least free up the user's hands to carry objects other than a chair and a bag. Moreover, when the chair is folded and being worn like a backpack, the container is still functional for storage of items in the container. Such straps also preferably do not interfere with the set-up condition of the chair, or with the collapsing of the chair, or affect use of the chair when so set up.
In another aspect of the present invention, the chair can include a shade that can be secured at side hubs to the chair frame on the back rest or on the rear legs of the chair frame, and generally comprises two arcing members each having at least one hinge to aid in the collapsing of the shade, as shown and described in Applicant's co-pending U.S. patent application Ser. No. 15/802,957, incorporated herein by reference. A flexible shade membrane or fabric materials extends between the arcing members. When the shade is in a set-up condition, the membrane is generally taut. The shade can be collapsed, and when so collapsed, the membrane is folded between the arcing members and ultimately folded within or adjacent to the chair frame members as the chair is collapsed. In preferred embodiments, the position of the shade over the head of a seated user sitting in the set-up chair can be adjusted via movement at the side hubs, and still more preferably, locked into certain positions once adjusted, as desired. When the shade is collapsed and folded against the chair back, it can be positioned around the storage container so as not to interfere with use of the container.
These and other objects, features and advantages of the present invention will become apparent in light of the detailed description of embodiments thereof, as illustrated in the accompanying drawings.
Referring to
More particularly, the side frame members are arranged symmetrically in a left plurality 12 and a right plurality 14. Each plurality 12 or 14 of side frame members includes a front leg 16, a rear leg 18, a seat support 20, an armrest 22, and a back support 24. The front legs 16 are cross-connected by a lower leg brace 26 and an upper leg brace 28. The rear legs 18 are cross-connected by a rear brace 30. The back supports 24 are cross-connected by a top brace 32.
Each front leg 16 is pivotally connected to its respective seat support 20 by a front joint 42, and is pivotally connected to its respective rear leg 18 by a wrist joint 44. Each seat support 20 is pivotally connected to its respective back support 24 by a seat joint 46. Each seat joint 46 also connects its respective seat support 20 and back support 24 to a crank 48, which is connected by a crank joint 50 to the respective rear leg 18. Finally, each armrest 22 is pivotally connected to its respective back support 24 by an elbow joint 52, and is adjustably attached to its respective front leg 16 (at or near the wrist joint 44) by a ratchet mechanism 60.
Each member of the chair has a diameter or thickness, and conventionally all members of such chairs have been of a uniform diameter or thickness. Also, conventionally, the members of such chairs have been arranged in a stacked configuration in which they fold down against each other. Thus, for an arrangement of four side frame members, the known chairs when fully folded occupy the thickness of four side frame members.
With reference to the set-up configuration of the chair 10, as shown in
Referring further to
Moreover, the carrying strap 66 may be duplicated with the duplicate strap being attached at the side of the top brace and at the other rear leg 18. Accordingly, when the chair 10 is in its flattened condition, both of the duplicate carrying straps may be used to carry the chair over both shoulders like a backpack.
In accordance with preferred embodiments of the present invention, the chair 10 includes a storage container 80 on the backside of the back rest panel 64, as shown in
In a preferred embodiment, the container 80 is a cinch-style container that can be easily dosed to secure and protect the items contained therein, thereby providing extra security from theft (e.g., at the beach or a park where the user may occasionally stray away from the chair 10). The storage container 80 can be used to hold and store a variety of items, such as, a wallet or purse, a phone or tablet, car keys, extra clothing, snacks, sunscreen, and the like.
Referring to
In embodiments of the present invention, the open top end 82 of the container 80 can be closed using a cinching means, generally designated as reference numeral 84. For example, a single rope 86 anchored on each side of the container 80 can be provided and fed through openings or grommets 88 in the container fabric in an alternating threaded fashion, whereby the center of the rope 86 can be pulled in a center portion of the container 80 to tighten and gather the fabric material around the open top end 82 to close the opening. Alternatively, two ropes can be used—more particularly, a left rope and a right rope, each anchored on a respective side of the container 80 and fed through openings or grommets 88 in the container fabric to meet in a middle portion of the container 80, whereby, again, pulling on the ropes will gather and cinch the opening of the container 80 closed. To open the container 80, the rope 86 can be relaxed and the fabric along the opening of the container 80 can be pulled open so as to gain access to the interior of the container 80 and objects contained therein.
A sleeve can be provided for essentially locking the container 80 closed. That is, the sleeve is included on the slack of the rope or ropes 86 at the middle of the container 80. When the rope 86 is pulled to close the opening, the length of rope in the middle relative to the fabric of the container 80 increases. The sleeve can be slid toward the container fabric, as illustrated in
The container 80 in accordance with the present invention may also be used on a chair style 300 having a folding shade 200 attached to the back rest of the chair frame, such as described and shown in Applicant's co-pending U.S. patent application Ser. No. 15/802,957, filed Nov. 3, 2017, and entitled “Transverse Folding Shade,” the disclosure of which is incorporated by reference herein in its entirety.
Referring to
The present invention permits use of a folding shade 200 that may close and/or fold without being removed from the folding furniture that it is permanently or removably attached to. This feature advantageously allows the folding shade to travel and/or be stored with folding furniture when the folding furniture is also closed and/or folded instead of being required to be separately removed for such travel or storage applications. Further, the since the folding shade is configured to close and/or fold while attached to folding furniture, the folding shade may not add any extra width to the folding furniture footprint when in the folded the position.
