The present invention is a construction plate and system made of a series of construction plates. The construction plate is a flat sheet of generally square or rectangular material having a length to width ratio of particular dimensions with at least one opening about its center having slots along the top and bottom edges for connecting the construction plates together. The construction plate may additionally have indentations along the top edge for integrating with other construction plates, slots on the left and/or right side edges for receiving other construction plates, apertures near the corner of the top edge and left side and/or right side edges and near the corner of the bottom edge for receiving dowels or poles for hanging items and the at least one opening and/or top edge of the flat sheet may have keyhole shaped apertures extending toward said bottom edge of said flat sheet.

A panel may be configured with panel mounts by forming a panel connector accepting slot in the panel and then locating connector mounts in the slot. In another embodiment, a panel may be configured with panel connector mounts by milling a panel to leave areas of panel material which form the mounts and milling the panel behind to connector mounts to define areas for accepting portions of the panel connector. Panels having the defined connector mounts may be connected by one or more panel connectors which engage the connector mounts.

A gravity-orientation coupler is shown and described. The gravity-orientation coupler includes a first coupler half and a second coupler half, wherein the coupler halves are shaped to fit flush together. Each coupler half is comprised of a tongue having a ball chamber which is located within one end of the tongue. The ball chamber movably houses a ball. The ball chamber has an opening located at one side. The tongue of one coupler half is configured to align with and fit flush against the other coupler half. The ball and ball chamber are configured such that when the coupler halves are fitted together the ball in at least one of the ball chambers will apply pressure to the respective tongue securing it therein.

The present invention includes a multiuse clip assembly which can be employed to secure objects or panels to one another. It incorporates both the male and female features into each clip for greater versatility and durability over conventional clip systems. The unique universal and expandable mating system does not limit the orientation, position, or number of objects or panels that may be secured to one another.

A kit forms a display case or a part of a display case. The kit has at least one frameless side panel with a panel front side, a panel back side, a panel edge extending between the panel front side and the panel back side and four panel corners, and at least one profile strip, which extends along the panel edge from a first of the side corners to a second of the side corners. The profile strip has a fixation section covering either the panel edge and the panel back side in an edge region, or only the panel back side in an edge region, or only the panel edge, and a holding section being subsequent to the fixation section holding a cover or bottom plate. By the kit the display case can be assembled solidly and is easily disassembled.

A modular furniture system includes a plurality of panel elements having opposing first and second major faces, a perimeter wall defining a minor face therebetween, and at least a boss aperture which passes through the first and second major faces. A panel connector has a bridging element and at least two bosses in spaced apart relationship on the bridging element, each boss being a complementary fit in the boss aperture of a respective panel element, a first fastener recess in a distal free end of each boss, and a second fastener recess opposing the first fastener recess and adjacent to a proximal end of each boss. An oversized fastener associated with each boss has a panel-retaining head and a tail which is interengagable with the panel-retaining head.

A connector is provided. The connector includes a post defining a first side, a second side, and a first end. The connector further includes a stationary wing formed on the first side of the post and extending away from the first side of the post. The stationary wing is inflexible relative to the post. The connector further includes a flexible wing attached to the second side of the post adjacent to the first end and extending away from second side of the post. The flexible wing is configured to flex relative to the post.

A clip for attaching an attaching article to an object member may include an engagement claw configured to engage an attaching hole formed in the object member. The clip may also include a slide body configured to retainably hold the engagement claw on the attaching article and configured to slide the engagement claw with respect to the attaching article so as to project and retract the engagement claw. The clip may also include an elastic body configured to apply a restoring force to the engagement claw when the engagement claw slides from a projected state to a retracted state with respect to the attaching article, so as to provide a biasing force to return the engagement claw toward the projected state.

A panel may be configured with panel mounts by forming a panel connector accepting slot in the panel and then locating connector mounts in the slot. In another embodiment, a panel may be configured with panel connector mounts by milling a panel to leave areas of panel material which form the mounts and milling the panel behind to connector mounts to define areas for accepting portions of the panel connector. Panels having the defined connector mounts may be connected by one or more panel connectors which engage the connector mounts.

Building panels including a first and a second panel and including a locking device. The locking device includes a tongue and an edge groove provided in the second panel and the first panel, respectively, wherein the tongue and the edge groove are configured to cooperate with each other for locking a first edge portion of the first panel to a second edge portion of the second panel in a first direction. The locking device further includes a separate tongue provided in an insertion groove and a tongue groove configured to cooperate with each other for locking the first edge portion to the second edge portion in a second direction. A length of the tongue groove along an edge portion may be smaller than a length of the edge portion. A length of the insertion groove along an edge portion may be smaller than the length of the edge portion.
