Connectors for assembling off-the-shelf framework such as pipes and tubes. The connectors include parts that can have puzzle-shaped ends for locking the components together, and when connected, the connectors form various cavities that may include friction-inducing components disposed in the cavities to render the framework stationary. The cavities may be sized to accommodate different sizes of framework.

The present disclosure relates to configurable stacking chairs having a standard seat base frame design to which different interchangeable seat backs can be quickly and easily attached. The seat base frames and the interchangeable seat backs may include corresponding quick-connect features that allow selective attachment therebetween. The interchangeable seat backs may be attached to a standard seat base frame via a magnetic connection. Each interchangeable seat back can have a different unique design allowing for a quick change of appearance by exchanging one interchangeable seat back design for another. The interchangeable seat backs and the standard seat base frames can be stored separately and take up less space than completely assembled or fixed back chairs.

A connecting assembly for a sofa includes a first connecting piece fixing on a first component of the sofa, a second connecting piece fixing on a second component of the sofa, and a third connecting piece. The first connecting piece includes a first inserting portion. The second connecting piece includes a second inserting portion. A first end of the third connecting piece is inserting into and connecting with the first inserting portion. A second end of the third connecting piece is inserting into and connecting with the second inserting portion. When the third connecting piece is gradually inserting into the first inserting portion and the second inserting portion, contact pressures between at least portions of the third connecting piece, the first inserting portion and the second inserting portion gradually increases to make the third connecting piece clamping to the first inserting portion and the second inserting portion.

A connector for connecting discrete modular storage units defined by plural hollow elongate support members having longitudinal ends including apertures into which vertical connection members can be inserted to connect adjacent modules. The inserts may be of a predetermined length to connect two horizontally adjacent modules or a length twice the predetermined length to connect two horizontally adjacent modules. For vertically and horizontally connected modules, the inventive connector may be utilized to connect modular shelving units having both an in-line and perpendicular configuration. The connector ideally comprises two identical insert members joined to each other in a desired orientation, so that the modules can be connected in different configurations, whether in-line, staggered or perpendicularly. The inventive connector also vertically connects the horizontally configured shelving modules to a variety of vertically disposed and configured shelving module units in a desired configuration. The connectors can be used to provide for an end connection at a top or bottom of the configuration in a dual insert connector, enabling a tab member to engage onto and retain an adjacent hollow tubular member or, in a single insert embodiment, to provide for insertion of a caster for resting on a floor.

The present invention provides a furniture installation component comprises a connecting member, elastic members, a cross member and a T-shaped member. The elastic members are ring structures and covered on the grooves. The cross member is formed by connecting the first hollow pipe member and the second hollow pipe member, and has four first connecting holes. The T-shaped member is formed by connecting the third hollow pipe member and the fourth hollow pipe member, and the T-shaped member has three second connecting holes. The connecting member passes through the cross member and the T-shaped member through the first connecting hole and the second connecting hole. Therefore, the furniture installation component of the present invention can avoid the use of excessive hardware parts and tools, and can avoid the deterioration of the stability of the furniture after repeated disassembly and use, thereby facilitating the purpose of assembly, disassembly and carrying.

Provided is a coupling system comprises a first tubular member with a top end and a second tubular member with a bottom end, defining together a longitudinal axis. One of the top end of the first tubular member and the bottom end of the second tubular member is configured with a longitudinal axially extending socket portion. The other one of the top end of the first tubular member and the bottom end of the second tubular member is configured with a longitudinal axially extending plug portion for coaxial snug receipt within the socket portion. Each tubular socket portion and the plug portion is configured with a lock opening intersecting the longitudinal axis. The coupling system includes a locking plug configured for locking engagement of the lock openings while in register with one another, thereby preventing axial or rotary displacement of the first tubular member and the second tubular member.

A boat chair configured such that it may be converted between several storage and/or use configurations and may be detachably affixed to and removed from a boat or placed on a boat using a free-standing stand. The boat chair may be configured such that the boat chair may be used in multiple use positions and may be transitioned into one or more storage configurations to allow for the boat chair to be more easily transported and/or stored. The boat chair may further be configured such that the use configurations may allow for customized position and/or use of the boat chair on a boat, including use of a free-standing stand for the boat chair.
