This disclosure relates generally to collapsible furniture which can be simply assembled without the need for any conventional fastening means and can be easily fabricated.
Conventional furniture construction uses glue and/or fasteners installed with tools. Once the conventional furniture has been assembled, shipping and storage costs are increased due to the size of the assembled conventional furniture.
Collapsible furniture is known in the art. For example, U.S. Pat. No. 5,387,027 proposes take-apart furniture. A disadvantage associated with the proposed take-apart furniture is that the members therein tend to slide causing structural instability.
The present disclosure provides a number of examples of novel and unobvious mechanisms for collapsible furniture which allow the furniture to be easy to assemble without the use of tools, structurally rigid when assembled in order to support added weight, and easy to disassemble. Collapsible furniture provides distinct advantages over conventional furniture for the purposes of shipping and storage.
In one example of this disclosure, collapsible furniture consisting of substantially planar members which positively interlock and reversibly unlock is provided. Interlocking members have respective, complementary locking means (for example, male and female components) to provide structural rigidity. The members also have nook components to aid in the disassembly of the collapsible furniture. The collapsible furniture of the present disclosure can be assembled without the use of any nails, screws, glue or any other fasteners or adhesives. Furthermore, the planar members may be easily disassembled and compacted into space-saving form for convenient transport and storage.
The techniques discussed in this disclosure can be applied to various collapsible furniture of assorted sizes and shapes, such as, for example, a bed, desk, table, shelf, stool, chair (such as dining chair, lounge chairs, loveseat, other furniture on which one can sit), etc.
The features of the present disclosure can be more readily understood from the detailed description below with reference to the accompanying drawings wherein:
a is a side view of interlocking means in an unlocked position according to an example of the present disclosure.
b is a side view of interlocking means in a locked position according to an example of the present disclosure.
In describing examples and preferred embodiments in connection with the drawings, specific terminology is employed for the sake of clarity. However, the disclosure of this patent specification is not intended to be limited to the specific terminology so selected, and it is to be understood that each specific element includes all technical equivalents that operate in a similar manner.
The interlocking means may comprise female components and complementary male components which when inserted in the female components and interlocked therewith secure the respective members to each other. For example, male components 6a and 6b of back member 30 can be inserted in female component 5a of side member 20a and female component 5b of side member 20b, respectively. In addition, male components 6c and 6d of seat member 40 can be inserted in female component 5c of side member 20a and female component 5d of side member 20b, respectively. Additional corresponding male and female component pairings may be interlocked to provide structural rigidity for the furniture structure including male components 6e and 6f of side members 20a and 20b inserted into female components 5e and 5f of seat member 40; male components 6i and 6j of back member 10 inserted into female components 5i and 5j of side members 20a and 20b; and male components 7a and 7b of back member 10 inserted into female components 8a and 8b of side members 20a and 20b.
a shows a side structural view of positive interlocking means in an unlocked position while
Male component 1 is preferably flexible enough to deflect at a dimension generally designated as numeral 8 such that hook portion 3 will be level with the rest of male component 1 when male component 1 is bent slightly in direction A. By allowing for such a deflection, hook portion 3 may be easily inserted into recessed portion 5. Once inserted, hook portion 3 is secured within recessed portion 5 at a dimension 8 to assure male component 1 and female component 2 are interlocked, providing structural rigidity for assembled furniture structure 100.
In addition, hook portion 3 is sloped at such an angle, generally designated as numeral 6, to allow hook portion 3 to be slidably inserted into recessed portion 5 of the female component 2. By including the positive interlocking means illustrated in
Nook portion 7 provides gripping means for reversibly unlocking male component 1 and female component 2. Although no tools are necessary for the assembly and disassembly of furniture structure 100, a tool, such as a screwdriver, may be inserted into nook portion 7 to act as a fulcrum in aiding in the unlocking of male component 1 and female component 2.
The members 10, 20a, 20b, 30, 40 and 50 may be made of any of the various materials used for furniture, such as plywood, plastic, other composite materials, etc.
The above specific examples and embodiments are illustrative, and many variations can be introduced on these embodiments without departing from the spirit of the disclosure or from the scope of the appended claims. For example, elements and/or features of different illustrative embodiments may be combined with each other and/or substituted for each other within the scope of this disclosure and appended claims.
