A furniture assembly system (10), comprising: a plurality of cross panels (100,100a), wherein each cross panel comprises a plurality of engaging apertures (102) of a right-angle cross shape arranged in one or more rows and one or more columns, with each engaging aperture being separated from an adjacent engaging aperture at a predetermined distance, at least one top panel (300) comprising a plurality of lock-down apertures, at least one support member (200,200a,200b), wherein the or each support member comprises a first interaction edge (201) and a second interaction edge (202) connectable to the cross panel, and a third interaction edge (203) connectable to the top panel, the first interaction edge and the second interaction edge being substantially perpendicular to the third interaction edge, and
wherein each of the first interaction edge and the second interaction edge comprises at least one hook joint (210) shaped and sized to be insertable into the engaging aperture of the cross panel and to extend beyond the cross panel forming a cantilevered projection, the third interaction edge comprises one or more protruding portions (220) shaped and sized to fit in the plurality of lock-down apertures (304) of the top panel.

The module comprises at least two front and rear chassis-frames, each with two right and left uprights and two top and bottom crosspieces, two right and left side walls inside the frames and a floor inside the frames bearing against the bottom crosspieces of the frames. The floor is arranged to oppose the movement of the bottom portions of the side walls towards each other. The uprights of the frames are arranged to oppose the movement of the side walls away from each other. The top portions of the side walls and the top crosspieces of the frames are arranged to oppose the movement of the side walls towards each other.

A rack has a frame and a plurality of shelves. Each shelf has an enclosing frame member that has two first sides connected by two second sides, a connecting bar that connects the first sides at about the center of the first sides, a plurality of slots provided on the inner surfaces of the second sides, and a plurality of slats, each slat having opposing ends that are fitted into opposing slots at the second sides, and with each slat being connected to the connecting bar. At least one connector is provided for removably connecting each shelf to a portion of the frame.

A shelving system formed by a plurality of vertical posts and horizontal traverses held together through frictional engagement. Disposed between each lateral pair of posts is at least one traverse which includes a male frictional engagement member configured to engage with a removable female frictional engagement member disposed on each post. The post and traverse engage with each other so as to create a proportional or supportive reaction force in response to any shear force applied to the shelving system. Each of the female frictional engagement members has a tapered edge which forms a closely fitted coupling between the post and each traverse. Each of the female frictional engagement members may be selectively disposed in one of a plurality of positions along the height of each vertical post. The shelving system further includes top and bottom connectors, both of which also frictionally engage with the vertical posts.

A connection arrangement for panels including a first panel having a first main plane and a second panel having a second main plane. The first main plane is essentially perpendicular to the second main plane in a connected state. The second panel includes a groove on a first face adapted to receive a first edge of the first panel. The connection arrangement includes an elongate flexible tongue element arranged in an elongate insertion groove in the first panel at an angle of less than 45° relative the first main plane and arranged to cooperate with an elongate tongue receiving groove arranged in the groove of the second panel for connecting the two panels to one another. The elongate insertion groove and the elongate flexible tongue element are configured to extend through the plane of the first face of the second panel when the two panels are in a connected state.

An air conditioning apparatus for cooling and/or dehumidifying an interior space, such as the interior of a shelter or tent that provides for simplified manufacturing, simplified inspection and servicing, reduced noise, reduced vibration, reduced weight, increased ruggedness and health monitoring. Structural components of the apparatus are fabricated from foam-filled molded parts with interlocking components, and the unit is assembled and tested without any outside cover, but once the cover is installed, additional structural strength is obtained from the cover. A refrigerant flow sensor along with other sensors are used to determine actual real time cooling capacity measurements and health monitoring.

Modular building blocks may be used to provide furniture or other items. Each modular building block has a number of interleaved layers that provide first and second arms of the building block. Each modular building block comprises a first engageable finger section formed from one or more of the interleaved layers and a second engageable finger section formed from two or more interleaved layers. The second engageable finger section of one modular building block receives the first engageable finger section of another modular building block allowing various arrangements to be assembled.

An assembled product includes at least three elements arranged in three different planes. A first element is connected perpendicular to a second element, and a third element is connected perpendicular to the second element. The assembled product includes one or more locking devices, each comprising a flexible tongue arranged in an insertion groove one of the at least three elements. The flexible tongue cooperates with a tongue groove, at an adjacent one of the at least three elements, for locking the one element and the adjacent element together. A second edge of the second element is connected to a second edge of the third element by a first of said locking devices.

A single dovetail tenon joint mechanism has a first panel and a second panel; the first panel is provided with a single dovetail tenon groove; the cross-section of the single dovetail tenon groove is a right-angled trapezoid; the right-angle sides of the right-angled trapezoid are near the edge side of the first panel; the long base of the right-angled trapezoid is located at the deepest part of the single dovetail tenon groove; one end of the second panel is provided with a single dovetail tenon that matches the single dovetail tenon groove. The single dovetail tenon is wedged into the single dovetail tenon groove for attachment therewith. During installation, a single dovetail tenon can be inserted from one end of the single dovetail tenon groove, thereby attaching the first panel to the second panel.

This disclosure relates to a drying rack for wet equipment constructed to support wet equipment having absorbent and non-absorbent sides. The drying rack supports the equipment such that absorbent sides of the wet equipment are generally oriented in a single windward direction relative to an external airflow source.
