Abstract

A furniture assembly and/or a mechanical coupling system for coupling furniture parts together to form an assembled article of furniture. The furniture assembly may include first and second furniture parts, each of which includes a board or other structural member and a coupler. The first furniture part may include a male coupler attached to the board and the second furniture part may include a female coupler attached to the board. The male and female couplers may be coupled together to thereby couple the first and second furniture parts together to form the assembled article of furniture. The male and female couplers may include engagement features that facilitate the coupling of the furniture parts together and to prevent them from becoming detached during normal use of the assembled article of furniture.

First claim

What is claimed is:

1. A furniture assembly comprising:
a first furniture part comprising:
a first board having at least one first aperture; and
at least one male coupler coupled to the first board, the male coupler being monolithic and extending from a first end to a second end along a first longitudinal axis, the male coupler comprising a first portion that includes the first end and a second portion that includes the second end, the first portion being positioned within the first aperture of the first board and the second portion protruding from the first board and comprising at least one first engagement feature;

a second furniture part comprising:
a second board comprising a front surface having at least one second aperture; and
at least one female coupler coupled to the second board, the female coupler being elongated along a second longitudinal axis and comprising:
a bottom end and a top end, the female coupler positioned within the second aperture so that the top end is flush with the front surface of the second board; and
an inner surface that defines a cavity having a cavity axis and comprising an insertion portion, a nesting portion, and a locking portion, a width of the cavity measured in a direction transverse to the second longitudinal axis increasing from a first end of the nesting portion that is adjacent to the insertion portion to a second end of the nesting portion that is adjacent to the locking portion, wherein along the nesting and locking portions the inner surface comprises a middle portion, a lower portion extending from the middle portion to the bottom end of the female coupler along a first plane that is oriented at an acute angle relative to the cavity axis, and an upper portion extending from the middle portion to the top end of the female coupler along a second plane that is oriented at an acute angle relative to the cavity axis; and

wherein the second portion of the male coupler is inserted into the insertion portion of the cavity of the female coupler and then slid to the locking portion of the cavity in a direction of the second longitudinal axis of the female coupler, the inner surface of the female coupler along the nesting and locking portions forming at least one second engagement feature that mates with the first engagement feature of the male coupler to couple the first and second furniture parts to one another; and
wherein the female coupler is compressed inwardly towards the second longitudinal axis by a sidewall of the second aperture of the second board to reduce the width of the cavity at the first end of the nesting portion thereby creating a snap-over feature that locks the male coupler to the female coupler as the male coupler slides past the snap-over feature.

2. The furniture assembly according to claim 1 wherein the first portion of the male coupler comprises a plurality of barbs that engage a sidewall of the first aperture to couple the male coupler to the first board, and wherein an outer surface of the female coupler comprises a plurality of barbs that engage a sidewall of the second aperture to couple the female coupler to the second board.

3. The furniture assembly according to claim 1 wherein the inner surface of the female coupler comprises a first portion located on a first side of the second longitudinal axis and a second portion located on a second side of the second longitudinal axis, and wherein the first and second portions of the inner surface of the female coupler diverge from one another as they extend from the first end of the nesting portion to the second end of the nesting portion.

4. The furniture assembly according to claim 1 wherein the first engagement feature comprises a groove and the second engagement feature comprises a protuberance.

5. The furniture assembly according to claim 1 wherein the second portion of the male coupler has an hourglass shape comprising a waist portion that forms the first engagement feature and wherein the inner surface of the female coupler has a protuberance along the nesting portion of the cavity that forms the second engagement feature, and wherein the protuberance is configured to nest within the waist portion to couple the male and female couplers to one another.

6. The furniture assembly according to claim 1 wherein the female coupler is a solid structure that is free of any apertures extending in a direction of the cavity axis, and wherein the male coupler is a solid structure that is free of any apertures extending in a direction of the first longitudinal axis.

7. The furniture assembly according to claim 1 wherein each of the first and second planes intersects the cavity axis at a location that is external to the cavity.

8. The furniture assembly according to claim 1 wherein the second portion of the male coupler comprises an upper portion that is adjacent to the first portion of the male coupler and a lower portion that extends to an end of the male coupler, the upper and lower portion converging at a waist portion, and wherein the inner surface of the female coupler along the nesting portion of the cavity comprises the upper portion that extends from the top end of the female coupler to an apex formed by the middle portion of the inner surface and the lower portion that extends from the bottom end of the female coupler to the apex, the apex of the inner surface of the nesting portion of the female coupler nesting within the waist portion of the second portion of the male coupler when the male and female couplers are coupled together.

9. The furniture assembly according to claim 1 wherein the first and second boards are formed from fiberboard and wherein the male and female couplers are formed from plastic.

10. The furniture assembly according to claim 1 wherein the first portion of the male coupler forms a first axial portion of the male coupler and the second portion of the male coupler forms a second axial portion of the male coupler, the first and second axial portions extending along the first longitudinal axis without overlapping, and wherein the second portion of the male coupler and the nesting and locking portions of the cavity of the female coupler have an hourglass shape.

11. A furniture assembly comprising:
a first furniture part comprising:
a first board having at least one first aperture; and
at least one male coupler coupled to the first board, the male coupler being monolithic and extending from a first end to a second end along a first longitudinal axis, the male coupler comprising a first portion that includes the first end and a second portion that includes the second end, the first portion being positioned within the first aperture of the first board and the second portion protruding from the first board and comprising at least one first engagement feature;

a second furniture part comprising:
a second board comprising a front surface having at least one second aperture; and
at least one female coupler coupled to the second board, the female coupler being elongated along a second longitudinal axis and comprising:
a bottom end and a top end, the female coupler positioned within the second aperture so that the top end is flush with the front surface of the second board; and
an inner surface that defines a cavity having a cavity axis and comprising an insertion portion, a nesting portion, and a locking portion, a width of the cavity measured in a direction transverse to the second longitudinal axis increasing from a first end of the nesting portion that is adjacent to the insertion portion to a second end of the nesting portion that is adjacent to the locking portion, wherein along the nesting and locking portions the inner surface comprises a middle portion
