Description

Technical Field

[0001] (Cross - Reference to Related Applications) This patent application claims the benefit and priority of U.S. Provisional Patent Application No. 62 / 930,775, filed on November 5, 2019. This patent application also claims the benefit and priority of U.S. Provisional Patent Application No. 63 / 021,074, filed on May 6, 2020. The contents of both provisional patent applications are hereby incorporated by reference in their entirety and for all purposes.

Background Art

[0002] In the portable chair industry, there is a market for high - performance folding chairs that can withstand frequent use efficiently and effectively and provide service to a large number of users. These seating situations are commonly seen in stadiums, arenas, lecture halls, schools, churches, and outdoor events such as picnics and concerts. Due to the general nature of the events, the performance requirements for these chairs can be very strict. For example, they need to withstand excessive use as commonly seen by sports fans and concert fans. Also, they need to provide comfort for long - term seating.

[0003] Many folding chairs tend to become uncomfortable, especially in situations with long seating times. For example, seats are usually made of rigid materials such as metal, plastic, and / or wood. Such materials can become even more uncomfortable over time as the surface deteriorates and weathers. These rigid seats may be covered with a layer of padding such as foam, but the thickness, elasticity, and quality may be insufficient.

[0004] Furthermore, these seat structures tend to ignore the contours of the human body. For example, the seating surface is generally one - dimensional, while the human body is clearly not so simple.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Folding chairs also tend to lack adequate back support. One reason is that back support is often kept to a minimum for the sake of folding operation and minimal storage space. For example, the backrest is usually much smaller than the human back. Backrests are often made of hard materials such as metal, plastic, or wood, which, as mentioned earlier, become uncomfortable over time and also disregard the contours of the human body. Like the seat, the backrest may be covered with a layer of padding such as foam, but this is not always sufficient. Also, backrests tend to be one-dimensional in contrast to the human body. As a result, there is a demand for high-performance folding chairs, especially for use in priority seating areas, and for folding chairs with seats and backrests that provide the durability required for heavy-duty use.

[0039] Embodiments of the present invention relate to a portable chair having superior skill and improved functionality. The portable chair includes a removable container, which, according to certain embodiments, can be insulated to keep beverages and food cold for extended periods. The chair is preferably designed and constructed to suit outdoor needs. The chair can be constructed of improved materials, including a frame made from aircraft-grade aluminum, according to some preferred embodiments. The chair may include a seat and back made of cloth webbing surrounding a nylon webbing core that is soft to the touch and maintains strength and "like new" comfort. The cloth webbing may include woven polyester cloth that can be made water-resistant. The chair may be fitted with wooden armrests that can be laminated and sealed for protection from natural forces. The armrests may be made of bamboo, which is lightweight, durable, and environmentally friendly.

[0040] Other improvements and features that demonstrate unique advantages include a variety of removable, reconfigurable, and / or interchangeable features, including an insulated container, a carrying strap, and a cup holder. The insulated container can be easily and conveniently attached to and removed from the folding chair. The insulated container can be welded, insulated, and sealed with an external pocket that is welded and sealed to protect what is contained inside. The strap can have multiple different attachment points. This allows for multiple different carrying styles and configurations, such as a backpack-type carrying configuration, a briefcase-type carrying configuration worn over the shoulder, and a satchel-type configuration worn across the body. The cup holder is interchangeable on both sides of the folding chair and can be designed to accommodate various different types of beverage containers, such as cups, cans, and water bottles with handles. Additional interchangeable accessory connectors can accommodate umbrellas, tables, fishing rod holders, etc., as will be understood in light of the teachings disclosed below.

[0041] According to several preferred embodiments, a removable insulated container can be designed to keep ice frozen for more than eight hours. The removable insulated container may have soft or hard sidewalls and construction, or a mixture of soft and hard sidewalls and construction. The folding chair and insulated container may include an external pocket for securely carrying and protecting additional items. Such an external pocket may be welded rather than sewn to ensure waterproof seams and a streamlined appearance. According to certain preferred embodiments, multiple carrying options provide a hands-free carrying experience designed for ergonomic comfort. Such multiple different carrying configurations are also useful for various carrying situations, depending on the environment and user needs.

[0042] According to a particular preferred embodiment, the removable container can be securely fastened to the underside of the chair's seat base frame via a clip such as a carabiner. Such a convenient connection allows for easy access to the contents of the insulated container. Furthermore, the insulated container can be easily detached from the seat frame of a folding chair, depending on the situation, to increase its portability or for separate use.

[0043] The hands-free carrying strap, in a satchel carrying configuration, crosses the chest, allowing the user's hands to freely carry additional equipment or items. According to various embodiments, the folding chair can be used to secure additional items such as snorkels, fins, and other items for any specific use within the folding chair.

[0044] The replaceable cup holder can be incorporated into a notch designed for cans, insulated water bottles, thermoses, and coffee mugs. Advantageously, the replaceable cup holder can be releasably coupled to an innovative frame element joint, rather than being positioned or formed on the armrest, providing not only the replaceable cup holder but also an improved ergonomic, multifunctional, parts-reduced, and versatile joint for rotatable frame element support.

[0045] Referring to Figures 1 and 2, an embodiment of a folding chair 100 including an insulated container 140 is shown. The folding chair 100 includes a folding chair frame. The folding chair frame may include a left arm support frame element 125A and a right arm support frame element 125B.

The cup holder 130 can be connected to and disconnected from the cup holder connectors 132 on each side of the folding chair 100 as preferred by the person sitting in the folding chair 100. Advantageously, the cup holder connectors 132 can be coupled, mounted, or attached to the front leg frame element 105, or they can also be coupled, mounted, or attached to the seat frame element 120. For example, the cup holder connector 132 may include an interlock or mating slot corresponding to an interlock or mating key or projection located on the cup holder 131.

[0052] Referring to Figure 3, a folding chair 100 containing an insulated container 140 is shown on the left side of Figure 3 with a person sitting in the chair, and on the right side of Figure 3 a person carrying the folding chair 100. As shown in Figure 3, the insulated container 140 is easily accessible to a seated person and, in its folded state, is easily carried by a connectable and reconfigurable strap 165.

[0053] Referring to Figure 4, the folding chair 100 is shown in three different configurations of one or more connectable and detachable carrying straps 165. In the first configuration on the left, the straps 165 are configured as a backpack. In the second configuration in the middle, the straps 165 are a briefcase-type strap carried over a woman's shoulder. And in the third configuration on the right, the reconfigurable straps 165 are in a satchel configuration that crosses a man's shoulder and chest.

[0054] Referring to Figure 5, an additional optional advantageous component of the insulated container 140 is shown. The insulated container 140 includes a handle 141. The handle 141 can be used to carry the insulated container 140 when it is removed from the frame of the folding chair 100.

[0055] The insulated container 140 can be connected and disconnected by front connectors 144 and rear connectors 145 of the insulated container 140. The front connectors 144 and rear connectors 145 may be in the form of loops, clips, or hooks that are attached to, coupled to, or connected to the insulated container 140, for example.

[0056] The insulated container 140 may also include one or more external pockets 142. For example, as shown in Figure 5, the insulated container 140 may include a pocket 142 equipped with a closing device such as a zipper. The insulated container 140 may include one or more bottom pockets 142 and / or one or more side pockets (not shown), as shown in Figure 5. In some embodiments, to ensure a watertight seam between the pocket 142 and the insulated container 140, the pocket 142 may be welded instead of sewn.

[0057] The folding chair 100 is shown in the figure as generally comprising a U-shaped front leg frame element 105, a U-shaped seat support frame element 120, a U-shaped rear leg support frame element 110, and a U-shaped back support frame element 115, interconnected by multiple couplings, folding joints, and / or pivotable joints. However, the back support frame element 115, the leg support frame elements 105 and 110, and the seat support frame element 120 can be implemented as individual or distinct parts. The use of U-shaped frame elements 105, 120, 110, and 115 results in various improvements, functional strengths, and ergonomic advantages, as discovered by the inventors of this patent application.

[0058] For example, as further shown in Figure 5, the folding chair 100 may include a chair frame having a left front leg frame element portion 105A and a right front leg frame element portion 105B. The left front leg frame element portion 105A may, but is not required, be connected to the right front leg element 105B by an interconnecting front leg frame element portion 105C. The elements of the front leg frame element 105 may be a single integrated support frame element in a U-shape, or separate individual parts according to embodiments not specifically shown. Any element of the frame element may be made from a single frame element that can be bent to perform a structural support function, or may be multiple individual support frame elements that can be joined together or designed for different configurations or individual functions.

[0059] Similarly, the rear leg frame element 110 may include a left rear leg frame element portion 110A and a right rear leg frame element portion 110B. The left rear leg frame element 110A may, but is not required, be connected to the right rear leg element 110B by an interconnecting rear leg frame element portion 110C. As shown, the elements of the rear leg frame element 110 may be a single part as shown, or separate parts (not shown) that can be joined together according to some embodiments.

[0060] Similarly, the seat frame element 120 may include two or more seat frame element portions. As shown in Figure 5, the seat frame element 120 may include a first seat frame element portion 120A and a second seat frame element portion 120B. The first seat frame element portion 120A may be the left seat frame element portion, and the second seat frame element portion 120B may be the right seat frame element portion 120B. The first seat frame element portion 110A may be connected to the right seat frame element portion 110B by an interconnecting seat frame element portion 110C. As shown, the elements of the seat frame element 120 may be a single part or separate parts. Similar teachings can be understood by reference to the back support frame element 115, as will be understood by those skilled in the art in light of the preceding teachings.

[0061] Referring to Figures 6-10, the folding chair may further include multiple couplings and joints adjacent to two or more of the front leg frame elements 105, rear leg frame elements 110, back support frame elements 115, seat support frame elements 120, and cup holder connectors 132. The couplings and joints may further include connectors for connecting the coupling joints to one or more carrying straps 165 and insulated containers 140, which may be integrated with them in some embodiments.

[0062] For example, the folding chair 100 may include two front couplings 170 and two rear couplings 180. The front coupling 170 may have a first front coupling joint 170A for connecting to the front leg frame element 105 and a second front coupling joint 170B for connecting to the seat frame element 120.

[0063] The first front coupling joint 170A is rotatably connected to the second front coupling joint 170B so that the seat frame element 120 is rotatably coupled to the front leg frame element 105.

[0064] As shown in Figure 7, the front coupling joint 170 may include a pivot rod 173 extending through the first front coupling joint 170A and the second front coupling joint 170A, the second front coupling joint 170B providing rotation of the first front coupling joint 170A relative to the second front coupling joint 170B while providing support for a person sitting on the seat of the folding chair 100.

[0065] The front coupling joint 170 may further include a first front coupling joint 171 for connecting a second front coupling joint 170B of each front coupling joint 170 to the insulated container 140. For example, as shown, the first front coupling connector 171 may have an integrated clip, such as a carabiner, for connecting to the front connector 144 of the insulated container 140. As shown in Figure 7, the front connector 144 of the insulated container 140 may be fixed to the top surface of the insulated container 140 or attached by a strap 146. The front coupling joint 170 may further include a second front coupling joint connector 172 for connecting and disconnecting the front coupling joint 170 to the end of a carrying strap (not shown), as shown in Figure 6.

[0066] The folding chair frame may further include two rear rotatable and folding couplings 180. The rear couplings 180 can foldably connect the end of the back support frame element 115 to the end of the seat support frame element 120. The rear couplings 180 can further rotatably connect the back support frame element 120 and the seat support frame element 120 to the rear leg frame element 110.

[0067] More specifically, as shown in Figure 7, the right rear coupling 180 is shown and includes two foldable rear coupling portions 180A and 180B. The first foldable rear coupling portion 180A connects to the back support frame element 115. The second foldable rear coupling portion 180B connects to the seat frame element 120. When in the folded position (not shown), the back support frame element 115 folds back relative to the seat support frame element 120. Furthermore, the rotational connection of the rear leg support frame element 110 to the rear coupling 180 allows the rear leg support frame element 110 to rotate to a position adjacent to and substantially parallel to the seat support frame element 120, the back support frame element 115, and the front leg support frame element 105. The rotation and support of the seat frame element 120 are made possible by a pivotable support rod 183 coupled to the rear leg frame element 110 by a rotational support frame arm 184.

[0068] The rear coupling 180 may further include a first rear coupling connector 181 for connecting the rear coupling 180 to the insulated container 140. The first rear coupling connector 181 can be formed integrally with a second portion 180B of the rear coupling 180. The first rear coupling connector 181 may be functionally analogous to a carabiner with a metal clip biased to the closed position.

[0069] The rear coupling 180 may further include a second rear coupling connector 182 for connecting to and disconnecting a carrying strap (not shown). Thus, the folding chair may include one, two, three, or four front and rear coupling joint connections for selectively connecting one or more carrying straps (see, for example, Figure 4) to each side of the front and / or rear of the seat by a second rear coupling connector 182 as shown in Figure 7, and a second fully coupling joint connector 172 as shown in Figure 6.

[0070] The folding chair section 100 may further include a seat support material 155 and a rear support material 150. The fabric of the seat support material 155 and the rear support material 150 may include fabric webbing in the form of fabric strips.
