Disclosed herein is an apparatus for mounting hardware to a surface of a structure. The apparatus includes a main body with an upper surface, a lower surface, and an outer edge. The apparatus also includes a distal pad with an upper and a lower planar surface, the distal pad being attached to the main body by at least two torsional joints. The apparatus also includes an attachment device with a contact surface, the attachment device is mounted to at least one of the planar surfaces. The contact surface is for engagement with the surface of the structure. The at least two torsional joints and distal pad may be manually rotated to achieve maximal surficial contact between the surface of the structure and the contact surface of the attachment device.

The present disclosure discloses plastic composite board comprising an upper board, a lower board, and a fastener. The lower board supports the upper board. The upper board comprises a panel and a downward edge disposed on a periphery of the panel. The periphery of the panel sinks downward to define a horizontal step surface, and the downward edge extends downward from an outer edge of the horizontal step surface. The fastener comprises a buckle groove. An inner side of the buckle groove defines an opening, and the buckle groove surrounds side portions of the upper board and the lower board to fixedly clamp the upper board and the lower board together. An upper wall of the buckle groove abuts the horizontal step surface, and a top surface of the fastener is lower than a top surface of the upper board.

A building unit is provided and includes a plurality of modular display panels and a plurality of modular display panel connectors. The plurality of modular display panels is positioned adjacent to each other in a grid shape array and extending between a display support structure having a plurality of interconnecting poles. The plurality of modular display panel connectors not in contact with the display support structure and connecting the plurality of modular display panels from a rear planar surface side of the plurality of modular display panels. Each modular panel connector is positioned along the rear planar surface side of the plurality of modular display panels and includes a plurality of fasteners securing the plurality of modular display panels in the grid shape array.

A modular wall overlay system for installation on a support surface includes a frame; and a cover securely retained on the frame by a tensioning system whereby the cover is free of direct attachment to the frame but rather is retained under tension on the frame by the tensioning system. The frame includes a plurality of frame pieces and a plurality of corner brackets. The frame pieces are directly coupled to respective corner brackets but are free of direct coupling to one another.

A shutter mechanism for a camera of an electronic device can include a slider mechanism that enables the shutter mechanism to operate between an open state in which a lens of the camera is exposed and a closed state that blocks the lens of the camera. The slider mechanism comprises a one or more slider appendages that operate the shutter mechanism between the open state and the closed state. Each of the one or more slider appendages slide along a horizontal axis in relation to a horizontal axis corresponding to the lens of the camera.

An electrical mating interface includes one or more electrical connectors that electrically couple the mounting device to a corresponding set of electrical connectors of an electronic device. The electrical mating interface further includes a front façade comprising a plunger coupled to a safety switch. The safety switch is disposed between the one or more electrical connectors and main wiring of a dwelling. When the plunger depresses upon coupling of the electronic device to the electrical mating interface, the safety switch closes and electrically couples the main wiring of the dwelling to the electronic device.

A fastener unit and related method for securing a board to a support is provided. The fastener unit includes a spacer block, a grip element extending from the spacer block and configured to fit in and engage a groove of the board, and one or more board engagement elements extending from a portion of the spacer block. The board engagement elements can clamp the board, between an upper and/or lower surface of the board and a groove of the board, thereby securing the spacer block in a position adjacent the groove to establish a gap between the board and another board. Related methods of use also are provided.

Provided is a swingable connection structure capable of detachably connecting a first member and a second member to each other easily. The swingable connection structure has a first member, a second member, and a swing holding member, and the second member is swingably connected to the first member. The first member has a swing shaft which defines a swing center axis of the second member, and the second member has a pivotally supported portion which receives the swing shaft. The swing holding member is mounted on a side surface of the second member in a rotatable manner, and the swing holding member is provided with a constraining hole which allows insertion of one end portion of the swing shaft received by the pivotally supported portion.

A modular wall overlay system for installation on a support surface includes a frame; a cover that is securely, yet detachably, retained on and along a front face of the frame by a tensioning mechanism that is configured to tension the cover; and elastic corner inserts that are disposed in corners of the frame and include curved outer surfaces that are configured to permit the cover to be stretched over the elastic corner inserts creating radiused corners and preventing tearing of the cover in corners thereof when the cover is tensioned by the tensioning mechanism.

A modular wall overlay system for installation on a support surface includes an outer frame having a pair of opposing ends and a pair of opposing sides and a customizable inner frame that is coupled to the outer frame. The inner frame includes a plurality of transverse supports that extend between the opposing sides and a plurality of longitudinal supports that extend between the opposing ends. The longitudinal supports and the transverse supports lie in a common plane defined within the outer frame. The system further includes a cover that is securely retained on the outer frame.
