Devices and methods based upon the concept of a split ring (604) having certain multiple interior angles (604a, 604b) to engage a stem or post (608) having annular ring(s) with angular geometries that are complimentary to those of the split ring. The disclosure provides designs for a wide range of insertion and desertion forces between latch engagement stems and latch engagement bodies. Changes to insertion contact angles and contact area on engagement stems and corresponding changes to insertion contact angles and engagement areas on engagement bodies can significantly modify insertion forces required to engage various devices. Similarly, changes in degrees of angle between desertion angles and contact areas on engagement stems with corresponding changes in desertion angles and contact areas on engagement bodies will significantly modify the total desertion forces required to disengage various devices. Accordingly, the instant latching mechanism provides insertion and desertion forces that can be controlled independently of each other.

1. A furniture locking assembly comprising: a stem having a first end and a second end, the first end of the stem connected to a first post by a first annular groove portion and the second end of the stem connected to a second post by a second annular groove portion, wherein a geometry formed by the first post and the first annular groove portion is identical to a geometry formed by the second post and the second annular groove portion,a first furniture board element, the stem being mountable within the first furniture board element, wherein the first post and the first annular groove portion extend out from the first furniture board element; anda second furniture board element having a hole formed in the second furniture board element, the hole defining a first portion sized to receive the first post and a second portion sized to receive the first annular groove portion,wherein the stem is configured to form two latch connections creating a joint between the first furniture board element and the second furniture board element, andwherein the stem has a central longitudinal axis extending from the first annular groove portion to the second annular groove portion, wherein the stem has a cross-section having a polygonal shape configured to inhibit rotation of the stem around the central longitudinal axis relative to the hole, wherein the cross-section is taken within a transverse plane perpendicular to the central longitudinal axis of the stem. 2. The furniture locking assembly of claim 1, wherein the first annular groove portion is configured to seat the first post and form a first latch connection. 3. The furniture locking assembly of claim 1, wherein the stem is formed of plastic, metal, or wood. 4. The furniture locking assembly of claim 1, wherein the second end of the stem is mounted in the first furniture element by an adhesive. 5. The furniture locking assembly of claim 4, wherein the first post and the first annular groove portion are received within the hole of the second furniture element by sliding into the hole. 6. The furniture locking assembly of claim 1, wherein the stem is a dual-ended reversible stem. 7. A furniture locking element configured to form two latch connections creating a joint between a first furniture board element and a second furniture board element, the furniture locking element comprising: a stem having a uniform outer diameter extending along a central longitudinal axis between a first end of the stem and a second, opposite end of the stem, the stem having a polygonal cross-sectional shape when taken within a transverse plane perpendicular to the central longitudinal axis of the stem, the shape configured to inhibit rotation of the stem around the central longitudinal axis relative to a hole within which the stem is positioned;a first post located distal to the first end of the stem;a first annular groove portion located between the first end of the stem and the first post, the first annular groove portion having a cross-sectional shape when taken within the plane perpendicular to the central longitudinal axis of the stem that is round;a second post distal to the second end of the stem; anda second annular groove portion positioned between the second end of the stem and the second post, the second annular groove portion having a cross-sectional shape when taken within the plane perpendicular to the central longitudinal axis of the stem that is round,wherein a geometry formed by the first post and the first annular groove portion is identical to a geometry formed by the second post and the second annular groove portion.
