Connectors used in modular furniture system
View Patent ↗A connector for connecting two furniture modules or other stationary objects to form a modular system. The connector includes two hardware pieces, to be mounted onto two furniture modules, respectively. The first piece fits into the second piece in a loading/unloading position, and then moves to a locked position. One or more detent on one hardware piece and one or more systems of tracks in the other hardware piece are provided to help the two pieces move relative to each other in a guided manner, go into and stay in the locked position, and move out of the locked position into the loading/unloading position when sufficient force is applied. Each system of tracks includes multiple indentations and one or more barriers, where the detent can move along the indentations and is resisted or blocked by the barriers.
1. A connector for joining two furniture modules or other objects, comprising:
a first hardware piece;
a second hardware piece having a main cavity for receiving the first hardware piece, wherein the first and second hardware pieces are in an unlocked state when the first hardware piece is received in the main cavity of the second hardware piece, the second hardware piece further having one or more receiving cavities connected to the main cavity for receiving at least a portion of the first hardware piece, wherein the first and second hardware pieces are in a locked state when the portion of the first hardware piece is received in the one or more receiving cavities of the second hardware piece, and wherein the first hardware piece is slidable along a first direction within the second hardware piece to change between the unlocked state and the locked state; and
a detent mechanism, including a first part disposed on a first one of the first and second hardware pieces and a second part disposed on a second one of the first and second hardware pieces, wherein the first and second parts of the detent mechanism engage with and cooperate with each other to hold the first and second hardware pieces in the locked state, and to allow the first and second hardware pieces to change from the locked state to the unlocked when a sufficient force is applied,
wherein the first part of the detent mechanism comprises a detent member affixed to the first one of the first and second hardware pieces, the detent member including a protruding end and a resilient biasing member, the resilient biasing member configured to urge the protruding end toward a second direction perpendicular to the first direction and is retractable in a direction opposite to the second direction when an external force is applied,
wherein the second part of the detent mechanism includes a track formed on the second one of the first and second hardware pieces, wherein the track includes a first section and a second section separated by a barrier, wherein the barrier protrudes in the direction opposite to the second direction relative to the first section and the second section, and
wherein when the first and second hardware pieces move between the unlocked state and the locked state along the first direction, the protruding end of the first part of the detent mechanism moves along the first section of the track and moves between the first section of the track and the second section of the track over the barrier, wherein the protruding end protrudes less in the second direction when it moves over the barrier, and wherein when the first and second hardware pieces are in the locked state, the protruding end is located in the second section of the track.
2. The connector of claim 1 , wherein the first section of the track includes a series of protrusions, indentations, and varying surfaces in a series configured to create mechanical interactions with the protruding end as the protruding end travels along the first section of the track.
3. The connector of claim 1 , wherein the track further includes a third section separated from the first section by another barrier, wherein the other barrier protrudes in the direction opposite to the second direction relative to the first section and the third section.
4. A connector for joining two furniture modules or other objects, comprising:
a first hardware piece;
a second hardware piece having a main cavity for receiving the first hardware piece, wherein the first and second hardware pieces are in an unlocked state when the first hardware piece is received in the main cavity of the second hardware piece, the second hardware piece further having one or more receiving cavities connected to the main cavity for receiving at least a portion of the first hardware piece, wherein the first and second hardware pieces are in a locked state when the portion of the first hardware piece is received in the one or more receiving cavities of the second hardware piece, and wherein the first hardware piece is slidable along a first direction within the second hardware piece to change between the unlocked state and the locked state; and
a detent mechanism, including a first part disposed on a first one of the first and second hardware pieces and a second part disposed on a second one of the first and second hardware pieces, wherein the first and second parts of the detent mechanism engage with and cooperate with each other to hold the first and second hardware pieces in the locked state, and to allow the first and second hardware pieces to change from the locked state to the unlocked when a sufficient force is applied,
wherein the first part of the detent mechanism comprises a detent member affixed to the first one of the first and second hardware pieces, the detent member including a protruding end and a resilient biasing member, the resilient biasing member configured to urge the protruding end toward a second direction non-parallel to the first direction and is retractable in a direction opposite to the second direction when an external force is applied,
wherein the second part of the detent mechanism includes a track formed on the second one of the first and second hardware pieces, wherein the track includes a first section and a second section connected by a barrier, and
wherein when the first and second hardware pieces move between the unlocked state and the locked state along the first direction, the protruding end of the first part of the detent mechanism moves along the first section of the track and moves between the first section of the track and the second section of the track by interacting with the barrier, wherein the protruding end protrudes less in the second direction when it interacts with the barrier, and wherein when the first and second hardware pieces are in the locked state, the protruding end is located in the second section of the track.
5. The connector of claim 4 , wherein the first section of the track includes a series of protrusions, indentations, and varying surfaces in a series configured to create mechanical interactions with the protruding end as the protruding end travels along the first section of the track.
6. The connector of claim 4 , wherein the track further includes a third section separated from the first section by another barrier, wherein the other barrier protrudes in the direction opposite to the second direction relative to the first section and the third section.
