An attachment assembly for use with furniture and other articles. The attachment assembly includes a connector assembly that is configured to engage with a rail. The connector assembly includes a first, fixed protrusion, a lever, a second protrusion extending from the lever, and a third protrusion positioned between the first protrusion and the second protrusion. The rail includes a lip and a cutout in the lip that is sized to receive the third protrusion. The rail is configured to retain the connector assembly. Pivoting the lever when the connector assembly is positioned within the rail is configured to cause the second protrusion to bear against a bottom surface of the rail, such that the first protrusion and the second protrusion frictionally engage the bottom surface of the rail and the third protrusion frictionally engages the lip to fixedly hold the connector assembly.

A frame for steel furniture and a frame assembly, wherein the frame has a simple structure due to having a press groove and a bent bar formed in a hollow bar, is easily assembled through a connecting part or the like, thus greatly reducing manufacturing, installation, and maintenance costs, and can be expanded as in various embodiments. The frame, which is for steel furniture and formed by a hollow rectangular bar, is characterized in that: the corner of the rectangular bar is press-processed by a jig having a predetermined thickness, thereby forming the press groove in two surfaces contacting the corner; the bent bar having an L-shape forms inside the hollow rectangular bar while the press groove is being formed; and threads for fastening a fastening screw are formed on one surface of the bent bar, wherein the one surface faces the press groove.

This museum showcase comprises a bearing frame and fixed and/or openable walls supported by the bearing frame. The bearing frame comprises a platform that includes joints connected to horizontal beams. The fixed and/or openable walls of the showcase are supported only by the joints. The weight of the walls is supported by the joints, whereas the horizontal beams are not subjected to significant stresses. It is thus possible to design the showcase in a particularly simple and therefore quick manner, choosing the lengths of each beam according to the dimensions of the showcase and leaving the support of the weights to just the joints.

A system is provided comprising a first furniture part (200) and a locking arrangement comprising a connector bracket (1) and a locking element (4). The first furniture part (200) comprises a recess (201) having an oblong shape comprising an insertion portion (203) and a locking portion (204), wherein the locking portion (204) along an inner wall comprises a groove (207). The connector bracket (1) comprises a base portion (2) having an extension adapted to extend along the first furniture part (200), and at least one protrusion (3) having a longitudinal extension extending transverse the extension of the base portion (2) and comprising a rim (7) extending transverse the longitudinal extension of the protrusion (3). The protrusion (3) is configured to be inserted into the insertion portion (203) and to be movable from the insertion portion (203) to the locking portion (204) by applying a force to the connector bracket (1) in a direction transverse to the longitudinal extension of the protrusion (3), whereby the rim (7) engages the groove (207). The locking element (4) being a flexible tongue (4) is integral with the connector bracket (1) and is configured to be inserted into the insertion portion (203), thereby preventing the protrusion (3) from being moved from the locking portion (204) to the insertion portion (203) and thereby releasing its engagement with the groove (207). The locking element (4) is configured to form a safety lock adapted for acting against a portion of an envelope surface of the protrusion (3) facing the insertion portion (203) of the recess (201). Also, a connector bracket and the use of such connector bracket is disclosed.

The present disclosure provides systems and methods for assembling a device while maintaining the aesthetic appearance and structural integrity of a visible surface of the device. In one or more implementations of the invention, a system includes a first assembly piece with an assembly region that comprises an opening defined by first and second connecting elements. The system further includes a second assembly piece and a fastening assembly, where a portion of the second assembly piece is shaped to fit within the assembly region opening and the fastening assembly spans the first and second connecting elements to secure the first assembly piece to the second assembly piece, and tightening of the fastening assembly causes the second connecting element to deform, pressing a surface of the second assembly piece against an adjacent surface of the first connecting element and retaining a substantially even visible surface of the device.

Described herein are securing devices configured to hold one object to another. In some embodiments the securing devices are specifically configured to connect an umbrella to a table. The securing devices can comprise a base component configured to receive a first object and one or more support components configured to connect the base component, and thus the first object, to a second object.
