Abstract

At least one furniture upright vertical posts or legs inserted into at least one opening in at least one furniture horizontal span (shelf, top, frame) to retain the span horizontally. Each post diverges from its apex to its base. Each opening is bounded by interior facing walls that diverge downward to complement divergence of the post at an elevated region of the post. The retention of the span at the elevated region of the post arises because of the complementary divergence, which restricts relative movement of the span relative to the post to only allow lifting of the at least one span relative to the at least one post and prevent the span from moving sideways relative to the post at an elevation of the elevated region and prevent the span from being lowered further along the post past the elevated region.

Dependent claims

A self-standing furniture unit;

comprising:
a post extending through an opening in a span in a self-standing position, the post having a base and an apex and having an exterior facing surface that diverges from the apex to the base to define a geometric shape selected from the group consisting of a cone and a pyramid, the opening being bounded by an inclined surface that is in abutment with the exterior facing surface of the post at an elevation that is lower than the apex and higher than the base as the post stands upright so that the apex is higher than the base, the span being retained because of the abutment at an elevation, the abutment restricting relative movement of the span with respect to the post by blocking the span from moving sideways subsequently and from being further lowered subsequently as the post remains upright, wherein the span is configured to become freed of the abutment only from lifting of the span relative to the post as the post remains upright in the self-standing position, the abutment lacking any hardware or adhesives.

A method of assembly a self-standing furniture unit;

comprising:
extending a post through an opening in a span in a self-standing position, the post having a base and an apex and having an exterior facing surface that diverges from the apex to the base to define a geometric shape selected from the group consisting of a cone and a pyramid, the opening being bounded by an inclined surface that is in abutment with the exterior facing surface of the post at an elevation that is lower than the apex and higher than the base as the post stands upright so that the apex is higher than the base;
and
retaining the span because of the abutment, at an elevation, the abutment restricting relative movement of the span with respect to the post by blocking the span from moving sideways subsequently and from being further lowered subsequently as the post remains upright, wherein the span is configured to become freed of the abutment only from lifting of the span relative to the post as the post remains upright in the self-standing position.
