Floor panels which are provided with a mechanical locking system including an extruded flexible tongue in a sidewardly open groove which during a vertical folding motion is bent horizontally. A tongue adapted for being received in a sidewardly open groove of a floor panel, wherein the tongue, which is an elongated extruded section, when received in the groove is bendable in a plane substantially parallel with a front face of the floor panel, such that the tongue is at least partially resiliently displaceable inside said sidewardly open groove in said plane during locking of the floor panel with another floor panel and wherein a vertical protrusion, serving as a friction connection between the tongue and the groove, is arranged at an upper or lower part of the tongue, wherein a total width of tongue varies in a longitudinal direction of the tongue.

A residential or commercial building, structure, or building component can include an exterior member, interior member, and plurality of cross-members spatially disposed therebetween. Each of the exterior member, interior member, cross-members can be formed from a multi-layered stack of polymeric material made by a layered three-dimensional printing process, and all can be monolithically integrated. An exterior surface region of the exterior member can have an integrally formed surface finish. Overlying finishing or connective layers can be added. The exterior and interior members can be configured in a parallel arrangement to form a rectangular or curve shaped building block. A fill material can be disposed into openings between the exterior and interior members, and an interior surface region at the interior member can include a cavity configured for an electrical box, plumbing, or a sensing device.

A retail display table includes a table top with openings, and a modular display mat disposed over each opening. Each of the modular display mats is movable between a closed position in which it covers its respective table-top opening, and an open position in which it is lifted above the table top so that a cavity underneath the modular display mat is accessible. Also, each modular display mat has holes to accommodate a configuration of displayed items, and is removable and replaceable with another modular display mat having a different configuration of holes to accommodate a different configuration of displayed items. A retail display system may include such a retail display table, along with other modular retail fixtures such as display walls with modular display wall inserts and retail counter units with modular display mats interchangeable with those of the retail display table.

A sheet metal connector is provided for connecting a brick wall to a second structural member, the connector is received in the mortar joint of the brick wall and is connected to second structural member. The connector is provided with zones of controlled bending and controlled stiffness to allow for controlled bending of the connector in the field.

Systems and methods for under-floor storage include a robotic retrieval system. The robotic retrieval system includes a robot disposed under an upper floor. The robot may retrieve and deposit objects in a space under the upper floor. A portal provides access to the space from above the upper floor. Objects are stored in locations within the space. The robot selectively locates and retrieves the objects.

Devices, structures, and methods for designing, constructing, and fitting modular structural building blocks together into a unified structure. Modular blocks are rapidly fit together into finished assemblies. Finished assemblies include reinforcing elements aligned in a structurally sound pattern. The unified structure includes walls, provisions for corners, and provisions for door/window spaces. The unified structure optionally includes raised floors or lowered ceilings, offset from ordinary associated height, using blocks disposed side-by-side with intermediate supports. The unified structure optionally includes one or more curved structures, such as vaulted ceilings, rounded walls or silos, tunnels, or otherwise.

Floor panels are shown, which are provided with a mechanical locking system on long and short edges allowing installation with angling of long edges and where the short edge locking system has a displaceable tongue that is displaceable essentially in one direction from an inner unlocked position to an final locked position.
