DETAILED DESCRIPTION

Systems and methods described herein provide a magnetic invisible shelf support device that when installed is concealed inside vertical and horizontal panels of the subject item of furniture or shelving. Systems and methods promote shelves to be affixed to vertical sidewalls of bookshelves, cabinets, cupboards, or similar items of furniture with the supporting hardware provided herein being completely concealed.

A magnetic casing is inserted inside an end panel of a shelf. A cylindrical insert with a hole in its center is firmly affixed into the vertical sidewall at the point where the shelf is to be joined.

The casing contains a horizontal sliding pin that is positioned immediately in front of the cylindrical insert such that the head of the pin is situated over the hole in the insert. When the bolt is magnetically caused to slide toward the insert, the pin emerges from the casing and protrudes deeply into the hole in the insert, securing the horizontal shelf to the vertical sidewall. A handheld magnet tool is used to horizontally move the pin forward and backward to its protruded or recessed position, respectively, to engage and disengage, respectively, with the insert.

The system, which may be referred to commercially as the INVISI-BOLSTER™, uses non-contact pass-through magnetic forces to lock and unlock the casing in the shelf and move the pin into and out of the insert in the sidewall or vertical panel. The handheld magnetic tool moves the pin that is within the casing. The casing itself is entirely inside the shelf except for its outermost surface that is flush with the surface of the end panel of the shelf that contacts the surface of the vertical sidewall and binds to it.

The user slides the magnetic tool along the surface of the shelf over the location of the casing. The magnetic forces of the tool contact the casing through the wood or particle board of the shelf and cause the pin in the casing to move in the direction in which the magnet is being moved and toward the hole in the insert. When disassembling the bookshelf or cabinet, the user slides the magnet in the opposite direction which causes the pin to withdraw from the hole in the insert, thus permitting the shelf and the vertical sidewall to no longer be joined.

Turning to the figures,FIG.1is a diagram of components of system provided herein according to an embodiment of the present disclosure. A system100is provided comprising a magnetic casing102. The magnetic casing102, hereinafter casing102, comprises a barrel104and a cover106. The cover106has a face108. There are two holes in the face108through which casing screws110a-bare used to attach the casing102to an end panel of a shelf or other horizontal panel that is to be joined with a vertical panel, for example a bookshelf interior sidewall. The casing102also includes a pin112which is an aluminum or other metal rod that resides primarily inside the casing102when the horizontal panel is not connected to the vertical panel but protrudes forth when moved as described herein, causing the panels to be joined.

The system100also comprises an insert114which is placed fully into a hole bored into the vertical panel at the point where the horizontal panel is to join the vertical panel. The insert114has a hole in its end that is not visible inFIG.1into which the pin112protrudes deeply to firmly affix the casing102to the insert114and the shelf or horizontal panel to the bookshelf sidewall or vertical panel. An insert screw116is shown inFIG.1protruding from the bottom of the insert114. While it appears that the insert screw116is part of the insert114, in embodiments the insert screw116is a separate component from the insert114and is placed through the hole in the bottom of the insert114and then turned to tightly affix the insert114into the bookshelf sidewall.

The system100also comprises a magnetic hand tool118that contains a magnet in its wider end or head area and is used to slide along the surface of the horizontal panel at the location of the casing102. The magnetic attraction of the hand tool118and the pin112allows the pin112to be moved toward or away from the insert114, even though the casing102is almost entirely inside of the wood panel. The magnetic forces penetrate the wood and allow the pin112to be moved even though there is no direct physical contact between the tool118and the casing102.

The casing102houses a ring magnet (not shown) inside the cover106near the pin112. The ring magnet aligns with the metal insert114for a quick attachment of the horizontal shelf panel and vertical side wall of the subject item of furniture. The attraction between the ring magnet of the casing102and the insert114facilitates an intuitive and rapid positioning of the shelves before the tool118is used to attract the bolt120and slide it into the insert114on the side wall.

To secure casing102into an end panel of a horizontal shelf for placement, a hole is bored into the end panel. An electric drill with a Forstner drill bit may be used for this task.

The Forstner bit may be used to drill more shallow holes or indentations for placement of the areas of the cover106slightly to the right and left of the area of the pin112. The cover106is wider than the barrel104which fits deeply into the hole drilled using the Forstner bit. The entire casing102, which includes the barrel104and the cover106, fits into the area drilled using the Forstner bit. The face108, which is the outer surface of the cover106, would be flush with the surface of the end panel of the shelf or horizontal panel when the casing102is fully installed into the horizontal panel with the casing screws110a-bfully screwed into the horizontal panel.

In an embodiment, a system for binding horizontal and vertical panels is provided. The system comprises a casing comprising a barrel and a cover, the casing inserted into an end of a horizontal panel. The system also comprises a cylindrical metal insert embedded into a first surface of a vertical panel. The system also comprises a sliding metal pin inside the casing that receives attraction with a magnet placed on a second surface of the horizontal panel proximate the casing. The pin moves, based on the received attraction and after the end of the horizontal panel is placed against the vertical panel at a location of the insert, the movement of the pin based on movement of the magnet. The pin also protrudes partially, based on the movement through a first hole in the cover, into a second hole in the insert.

The horizontal panel is a shelf, and the vertical panel is a sidewall of one of a bookshelf and a cupboard. The partial protrusion of and semi-permanent placement of a head portion of the pin into the second hole in the insert promotes the horizontal panel to bind to the vertical panel.

Binding of the horizontal panel to the vertical panel promotes storage of items on the horizontal panel. The magnet makes no physical contact with the casing or with the pin contained within the casing.

The magnet makes contact solely with the second surface. The magnet causes the pin to move solely by magnetic force through the horizontal panel and into the insert.

In another embodiment, a system for binding panels while concealing binding hardware is provided. The system comprises a horizontal panel and a vertical panel with area designated for placement of an end surface of the horizontal panel. The system also comprises a hollow casing placed into the end surface, an end portion of the casing flush with the end surface. The system also comprises a metal insert embedded into the vertical panel at the designated area. The system also comprises a sliding metal pin resident inside the casing that moves, based on receipt of an external force, toward a first hole in the end portion of the casing. The pin also extends partially through the first hole and into a second hole in the insert, the end surface of the horizontal panel having been placed against the vertical panel at the designated area prior to commencement of movement of the pin. The pin also remains semi-permanently placed with a head portion of the pin resident in the insert, the semi-permanent placement promoting binding of the horizontal panel to the vertical panel.

The external force is provided by a magnet placed on an external surface of the horizontal panel proximate a location of the casing inside the horizontal panel, the placement of the magnet attracting the pin. Sliding of the magnet along the external surface causes the pin to slide within the casing toward an edge of the horizontal panel.

The magnet makes no physical contact with the casing or with the pin contained within the casing. The magnet makes contact solely with the second surface and causes the pin to move solely by magnetic force through the casing and partially into the insert.

The horizontal panel is a shelf, and the vertical panel is an interior sidewall of one of a bookshelf and a cupboard. The semi-permanent placement of the pin is terminated when the bookshelf or cabinet is disassembled, and panels are disconnected.

In yet another embodiment, a method for assembling furniture with assembly hardware concealed is provided. The method comprises a portable magnet positioned on surface of a horizontal panel magnetically attracting a metal pin, the pin situated inside a casing contained within the panel. The method also comprises the magnet, based on the attraction and based on movement of the magnet along the surface in a first direction, causing the pin to move toward an edge of the panel and toward a first hole in the casing at the surface. The method also comprises the magnet further causing the pin to protrude partially through the first hole and into a second hole of a metal insert embedded into a vertical panel, the protrusion promoting binding of the horizontal panel to the vertical panel.

The method further comprises the magnet making contact solely with the surface and causing the pin to move solely by magnetic force through the casing and partially into the insert. The method further comprises the magnet moving in a second direction, the second direction opposite the first direction, to cause the pin to withdraw from the second hole and to promote decoupling of the panels.

The horizontal panel is a shelf, and the vertical panel is a sidewall of one of a bookshelf and a cupboard. Actions of the magnet and the pin promote binding of the panels. Binding of the horizontal panel to the vertical panel promotes storage of items on the horizontal panel. The metal insert is embedded into the vertical panel such that an outer surface of the insert is flush with a surface of the vertical panel.
