Description

TECHNICAL FIELD

The present disclosure relates to the field of furniture, and, more particularly, to furniture frames and related methods.

BACKGROUND

Many existing furniture pieces, especially in the case of increasing e-commerce applications, are often shipped in a dissembled state in separate packages. The users must then subsequently assemble the furniture pieces, and typically use screw type fasteners during the assembly. These approaches may have complicated assembly instructions, and may even require special tools for assembly, for example, power tools and specialty Allen wrenches.

In particular, e-commerce applicable approaches for chairs may have additional drawbacks. Typically, for chairs, the seat board, due to long-term use, receives a mutual shear force between the seat board and armrest components. This may cause fasteners to loosen during prolonged use. Further, in these approaches, disassembly of the chair may permanently affect structural strength of the fasteners.

SUMMARY

Generally, a chair assembly includes first and second arm rests, a backboard, a pair of first connection devices coupling the backboard between the first and second arm rests, a seat board, and a pair of second connection devices coupling the seat board between the first and second arm rests. Each first connection device comprises a first L-shaped anchor, a second transverse anchor, and first and second openings opposite to and receiving the first L-shaped anchor and the second transverse anchor for coupling. Each second connection device comprises a third L-shaped anchor, and a third opening opposite to and receiving the third L-shaped anchor for coupling.

In particular, the first L-shaped anchor may be canted at an angle with respect to the first and second arm rests and the backboard. For example, the angle may be less than 15°. In some embodiments, the second transverse anchor may comprise a snap fastener. In other embodiments, the second transverse anchor may include an elongate anchor extending through one of the first and second arm rests and the backboard. The second transverse anchor may comprise a housing coupled to one of the first and second arm rests and the backboard and receiving the elongate anchor. The elongate anchor may be L-shaped.

Also, the first opening and the third opening may each comprise an elongate opening, and the second opening may comprise a circle-shaped opening. The first and second arm rests, the backboard, and the seat board may be hollow.

Another aspect is directed to a method for making a chair assembly to be assembled by a user. The method comprises providing first and second arm rests and a backboard, forming a pair of first connection devices to be coupled between the backboard and the first and second arm rests, and providing a seat board. The method also includes forming a pair of second connection devices to be coupled between the seat board and the first and second arm rests. Each first connection device comprises a first L-shaped anchor, a second transverse anchor, and first and second openings opposite to and receiving the first L-shaped anchor and the second transverse anchor for coupling. Each second connection device comprises a third L-shaped anchor, and a third opening opposite to and receiving the third L-shaped anchor for coupling.

Each connection device 103a-103b, 105a-105b comprises one or both of a first L-shaped anchor 106, and a second transverse anchor 107. Each connection device 103a-103b, 105a-105b comprises one or both of first and second openings 110, 111 opposite to and receiving the first L-shaped anchor 106 and the second transverse anchor 107 for coupling.

Each of the first and second arm rests 101a-101b, the seat board 104, and the backboard 102 may comprise a hollow structure. Also, each of the first and second arm rests 101a-101b, the seat board 104, and the backboard 102 may comprise a rigid material, such as aluminum.

In some embodiments, the second transverse anchor 107 may comprise a snap fastener. Also, for the component carrying the second transverse anchor 107, the component may comprise a through-hole 112 for receiving the second transverse anchor 107 and being aligned with the second opening 111. The first opening 110 may comprise an elongate opening, and the second opening 111 may comprise a circle-shaped opening.

In the illustrated embodiment, only two connection devices 103a-103b comprise both the first L-shaped anchor 106 and the second transverse anchor 107, and both the first and second openings 110, 111 for coupling (i.e., the lower connection devices coupling the backboard 102 and the first and second arm rests 101a-101b). The other connection devices 105a-105b comprise only the first L-shaped anchor 106 and the first opening 110. Of course, in other embodiments, the other connection devices 105a-105b may also comprise both anchors and openings.

One aspect is directed to a method for making a chair assembly 100 to be assembled by a user. The method comprises providing first and second arm rests 101a-101b, providing a backboard 102, and forming a first pair of connection devices 103a-103b for coupling the backboard between the first and second arm rests. The method also includes providing a seat board 104, and forming a second pair of connection devices 105a-105b for coupling the seat board between the first and second arm rests 101a-101b. Each connection device 103a-103b, 105a-105b comprises a first L-shaped anchor 106, and a second transverse anchor 107, and first and second openings 110, 111 opposite to and receiving the first L-shaped anchor and the second transverse anchor for coupling.

Of course, in other embodiments, the position of the anchors and the openings may be reversed. Further, it should be appreciated that the connection devices 103a-103b, 105a-105b may be applied to other furniture items for quick assembly, such as tables, lounge chairs, couches, etc.

For assembly of the chair assembly 100, the seat board 104 is coupled to the first and second arm rests 101a-101b via the first L-shaped anchors 106 extending from the sides of the seat board, and the first openings 110 on the first and second arm rests. Then, the backboard 102 is coupled to the first and second arm rests 101a-101b via the L-shaped anchors 106 extending from the sides of the backboard. Once the backboard 102 is locked into position, the second transverse anchors 107 are positioned through the through-holes in the backboard and into the second openings 111 on the first and second arm rests 101a-101b. As perhaps best seen in FIG. 2, the backboard 102 abuts and retains the seat board 104 from sliding out of locked position.

Referring now to FIGS. 9-15, another embodiment of the chair assembly 200 is now described. The chair assembly 200 illustratively includes first and second arm rests 201a-201b, a backboard 202, and a pair of first connection devices 203a-203b coupling the backboard between the first and second arm rests.

The second transverse anchor 207a-207b illustratively comprises a housing 216a-216b coupled to the first and second arm rests 201a-201b and receiving the elongate anchor 207a-207b. The housing 216a-216b is positioned over the second opening. The housing 216a-216b may define a slotted recess to receive adjacent portions of the elongate anchor 215a-215b and to retain it therein.

Further, as shown in FIGS. 13-14, the first and second arm rests 201a-201b each illustratively comprises a passageway 217a-217b for receiving the second transverse anchor 207a-207b. The backboard 202 also illustratively includes a blind passageway 220a-220b for receiving distal ends of the second transverse anchors 207a-207b.

In some embodiments, the first and second arm rests 201a-201b, the backboard 202, and the seat board 204 may be hollow. In other embodiments, the first and second arm rests 201a-201b, the backboard 202, and the seat board 204 may be solid with respective recesses for the first, second, third, and fourth openings. As for material, the first and second arm rests 201a-201b, the backboard 202, and the seat board 204 may comprise any rigid material with sufficient mechanical strength, for example, metallic materials such as aluminum, or polymers, such as plastic polymers.

Also, the first opening, the third opening, and the fourth opening each comprises an elongate opening, which is similarly constituted to the first opening 110 of FIG. 4. The second opening comprises a circle-shaped opening, which is similarly constituted to the second opening 111 of FIG. 4.

In the illustrated embodiments, the first opening, the third opening, and the fourth opening are defined in each of the first and second arm rests 201a-201b. The first L-shaped anchor 206a-206b, the third L-shaped anchor 213a-213b, and the fourth L-shaped anchor 214a-214b are carried by the backboard 202 and seat board 204, and are respectively received within the first opening, the third opening, and the fourth opening. The second opening is defined within the backboard 202, and the second transverse anchor 207a-207b is received within the second opening. It should be appreciated that the placement of opening/anchor can be reversed, and is within the scope of the disclosed embodiments.

Another aspect is directed to a method for making a chair assembly 200 to be assembled by a user.

Each first connection device 203a-203b comprises a first L-shaped anchor 206a-206b, and a second transverse anchor 207a-207b, and first and second openings opposite to and receiving the first L-shaped anchor and the second transverse anchor for coupling. Each second connection device 205-205b comprises a fourth L-shaped anchor 214a-214b, and a fourth opening opposite to and receiving the fourth L-shaped anchor for coupling.

During assembly, the user would first assemble the seat board 204 and the first and second arm rests 201a-201b by aligning the fourth L-shaped anchor 214a-214b into the fourth openings. The user would then position the backboard 202 between the first and second arm rests 201a-201b, aligning the first L-shaped anchor 206a-206b and the third L-shaped anchor 213a-213b with the first and third openings respectively. Lastly, the user would insert the second transverse anchor 207a-207b to lock the assembly into place for use.

Advantageously, the chair assembly 100, 200 may be readily assembled without any tools (i.e., toolless assembly). Further, as noted herein above, the first L-shaped anchor 206a-206b, the third L-shaped anchor 213a-213b, and the fourth L-shaped anchor 214a-214b are vertically oriented and aligned with the shear forces imparted on the chair assembly 100, 200 during use. This may provide for a more durable chair assembly 100, 200. Further, the pair of first connection devices 203a-203b and the pair of second connection devices 205a-205b may be disassembled without degrading the physical integrity of the coupling.
