Friction joints for use with head mounted displays are disclosed herein. In various embodiments, a head mounted display includes a front display module and a strap assembly. The strap assembly includes first and second connectors coupling the strap assembly to the front display module. The connectors allow the strap assembly to be moved toward and away from the front display module. The connectors are coupled to the front display module with first and second friction joints.

A device for connecting two construction components (10, 12) that are have engagement structures (16) on two connection surfaces (14) that are facing each other, in which the components (10, 12) have at least two pairs of oppositely disposed circular arc-shaped engagement structures (16) each of which extends over an angle of not more than 180 and has at least one open end, the engagement structures being arranged such that the center of the circular arc of the engagement structure of one pair is different from the center of the circular arc of the engagement structure of each other pair, and at least two connectors (22) are provided, each of which has engagement structures (24) complementary to the engagement structures (16) of one pair and adapted to be inserted in a rotary movement into the two engagement structures (16) from the open end.

A furniture seat with a plurality of keyed slots on a bottom surface receives a plurality of feet. Each of the plurality of feet having a base portion and a unitary peg. The base portion providing a shape with downward taper to a floor engaging end with the peg extending upwardly from a seat engaging end. The peg of each foot having a key shape to interface with the key slots. The peg having a plurality of spring members unitary therewith that deflect as each peg is inserted into a respective key slot and that then retain the foot to the bottom surface of the furniture seat.
