DISASSEMBLED CHAIRS FOR SHIPMENT

Abstract

A chair suitable for disassembly and a shipping method for the disassembled chair, which arranges chair parts of multiple chairs in one container and saves shipping cost. The disassembled chair has at least a backrest porting and a seat portion with extending legs, each of which has multiple connecting holes allowing them to be connected by mechanical fastener, such as rivets or screws. The seat portions of multiple chairs can be inverted and stacked within each other and multiple backrests can be located above the stacked seats between their legs, all within a single container so that the shipping and storing costs are lower.

DETAILED DESCRIPTION OF THE INVENTION

[0022] The present invention relates to a device and a method for including one or more disassembled chairs in one shipment box or container. As shown in FIG. 1A, the chair of the present invention has a backrest portion 100. The backrest portion 100 has right tubular side portion 101 and left tubular side portion 103. In one embodiment, the backrest portion 100 can be in tubular shape. In some other embodiments, the backrest portion 100 can include an optional middle portion 104 that provides more back support to a user. Preferably, connection holes 102 are included in backrest portion 100, located at two ends of the backrest portion 100 as shown in FIG. 1A. A seat portion 105 forms a part of the chair of the present invention as shown in FIG. 1B. In some practical implementations, connection holes 107 are included near a top end of the seat portion 105, as shown in FIG. 1B. A mechanical fastener 110 is shown in FIG. 1C. Multiple mechanical fasteners 110 are included in the shipment to assist user's assembly process.

[0023] FIGS. 2A and 2B show an assembly method of the invention. FIG. 2A shows that the optional middle portion 104 is first fastened to the seat portion 105 by one or more mechanical fasteners 110. FIG. 2B shows that the tubular side portions 101 and 103 of the backrest portion 100 are fastened by at least one mechanical fastener 110 at each portion. The backrest portion 100 and the seat portion 105 are arranged in such a position that the connection holes 102 and 107 overlap, so that the mechanical fastener 110 can be used to fix the backrest portion 100 onto the seating portion 105. A practical implementation of the assembled chair is shown in FIG. 3.

[0024] FIGS. 4-7 show a shipping method for the chair of FIG. 3 in its disassembled state, which allows multiple chairs to be stored and shipped in one container. FIG. 4A shows a seat portion 105 arranged and placed in a shipping container 405 of suitable size with its seating surface 111 facing downward. FIG. 4B shows an alternative implementation in which multiple seat portions 105 are stacked together, arranged and placed in one shipment container 405. FIG. 5 is a top view of the box containing one or more seat portions 105. As shown in FIG. 5, other protection materials 410 can be included in the shipping container 405 to protect the chair surfaces. In some preferred implementations, protection materials 410 can be plastic bubble wraps and/or foam. Because the chair seat portions 105 are designed to stack one within the other, multiple seat portions 105 can be placed in a single container 405 depending on its height.

[0025] FIG. 6A shows six backrest portions 100 arranged and placed in a shipping container 405 of suitable size. Typically the backrest portion 100 is placed in the container 405 after the seat portions 105 are stacked therein, so the backrest portion 100 has to be designed so that the distance between tubular side portions 101, 103 is less than the distance between the legs 109 of the seat portion 105. In some preferred implementations, each backrest portion 100 is arranged with its top portion 106 resting at one side of the shipping container 405 against the bottom ends of the inverted legs 109 of the uppermost seat portion 105 and its bottom portion placed at the diagonal opposite side from the top portion 106 against the upper ends of the inverted legs 109 of the seat portion 105. FIG. 6B shows how the backrest portions 105 are crossed and arranged in the shipment container 405 of FIG. 6A.

[0026] FIG. 7 is a top view of the shipping container 405 containing one or more (in this case four) backrest portions 105 in crossed positioning on top of multiple (in this case four) inverted and stacked seat portions 105 with extending legs 109. As shown in FIG. 7, other protection materials 710 can be included in the shipping container 405. In some preferred implementations, protection materials 710 can be plastic bubble wrap and/or foam. Optional backrest middle portion 104 can be arranged and stored in the spare space of the shipping container 405.

[0027] As shown in FIG. 7 the backrest portions 100 inclined on opposite sides are laterally offset from each other. With a slight increase in the width and height of the container 405, additional (i.e., more than four) backrest portions 100 can be included in one container 405. Similarly, because of the way the seat portions 105 stack, with a slight increase in height, additional (i.e., more than four) seat portions 105 can be included in the one container 405.

[0028] In some practical implementations, the present invention, namely, the seat portion 105, the backrest portion 100, the optional backrest middle portion 104, and the mechanical fasteners 110, can be made of wood, metal, plastic, or any combination of these materials. In some practical implementations, certain chair parts, namely the seat portion 105, the backrest portion 100, and the optional backrest middle portion 104, can be upholstered.

[0029] While the present invention has been particularly shown and described with reference to preferred embodiments thereof; it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention, and that the embodiments are merely illustrative of the invention, which is limited only by the appended claims. In particular, the foregoing detailed description illustrates the invention by way of example and not by way of limitation. The description enables one skilled in the art to make and use the present invention, and describes several embodiments, adaptations, variations, and method of use of the present invention.
