Definitions

  • the present invention in some embodiments thereof, relates to a detachable hinge and, more particularly, but not exclusively, to a detachable hinge for wearable articles such as items of jewelry.
  • Detachable hinges generally involve an opening in the socket part of the hinge through which the pin may pass when suitably aligned.
  • the pin is not fully cylindrical, the cylinder being flattened in one orientation. As the flattened orientation is aligned with the slit in the socket, the pin can be removed.
  • U.S. Patent 782,428 teaches a detachable hinge for a swing door.
  • U.S. Patent 2,794,208 has an example of such a hinge for a detachable window sash.
  • U.S. Patent 4,603,452 teaches a detachable hinge with conveniently releasable hinge flaps that work using the same technique.
  • a detachable hinge allows two parts to be rotated about each other, and then with the correct alignment the two parts can be detached.
  • a disadvantage is that the detachment alignment position may be reached accidentally during normal rotation, leading to inadvertent detachment.
  • the problem can be solved by co-opting gravity, so that as well as alignment some at least minor lifting motion is required to detach the parts.
  • inadvertent alignment and detachment cannot easily be avoided.
  • the present embodiments are intended to address the above issue.
  • the present embodiments provide a detachable hinge with a fully cylindrical pin and no special alignment. Rather the hinge socket part is mounted on a contour of a resilient arm to allow normal rotation of the pin.
  • the hinge however is shaped with a lever extension part that operates at beyond the normal rotation to lever open the resilient arm to release the hinge.
  • a hinge arrangement for an article comprising a first part and a second part to be hingeably connected, the arrangement comprising: a hinge mounted on said first part between a first wall and a second wall, at least said first wall being resilient and having a contoured shape comprising first and second troughs separated by a peak;
  • a hinge grabbing member located on said second part and insertable into said first part, said hinge grabbing member comprising a recess for rotatably engaging said hinge and a surface for contacting said first wall along said contoured shape, said surface comprising an extension, said hinge grabbing member having a limited arc of rotation defined by said surface and said contoured shape, said contoured shape preventing tangential motion of said hinge grabbing member during engagement between said contoured shape and said surface, said extension being configured to engage with said peak when rotated beyond said limited arc of rotation, thereby to lever open said first wall and permit release of said hinge.
  • said extension comprises a wall of said recess with a right- angled protrusion.
  • the article may be a personal article, such as a jewelry article, including a bracelet or bangle.
  • a releasable hinge arrangement for an article comprising a hinge and a hinge socket, the hinge mounted on a resilient wall and the hinge socket comprising a leveraging extension, the leveraging extension pressing on the resilient wall when said hinge socket is rotated beyond a predetermined angle, to leverage said resilient wall against a second wall to allow release of said hinge.
  • FIG. 1A is a cross-section of a bracelet in a closed position, the bracelet comprising a hinge according to an embodiment of the present invention
  • FIG. IB is a perspective cut-away view in three-dimensions of the bracelet of Fig. 1A;
  • FIG. 2 is a cross-section of the hinge part of the bracelet of Fig. 1 A;
  • FIGs. 3 A and 3B are simplified cross sectional views of the bracelet of Fig. 1 in an open position
  • FIGs. 4A and 4B are simplified cross sectional views of the bracelet of Fig. 1 rotated beyond the open position so that the hinge grabbing member levers apart the walls of the bracelet to release the hinge;
  • FIGs. 5A and 5B are simplified cross sectional views of the bracelet of Fig. 1 rotated from the position of Figs. 4A and 4B in order to release the hinge;
  • FIG. 6 is a simplified cross sectional view of the bracelet of Fig. 1 showing the upper and lower arm parts released from each other;
  • FIGs. 7A and 7B are simplified cross sectional views of the bracelet of Fig. 1 with the hinge grabbing member reinserted.
  • FIGs. 8A and 8B are simplified cross sectional views of the bracelet of Fig. 1 showing the hinge grabbing member having re-engaged the hinge.
  • the present invention in some embodiments thereof, relates to a detachable hinge and, more particularly, but not exclusively, to a detachable hinge for wearable articles such as items of jewelry.
  • the present embodiments provide a detachable hinge with a fully cylindrical pin and no special alignment. Rather the hinge socket part is mounted on a contour of a resilient arm to allow normal rotation of the pin.
  • the hinge however is shaped with a lever extension part that operates at beyond the normal rotation to lever open the resilient arm and release the socket part from the contour. A backward movement of the hinge socket part then allows for the separation of the socket part from the pin and from the contour, to release the hinge.
  • FIG. 1A is a simplified cross-sectional diagram illustrating a bracelet to which a detachable hinge according to the present embodiments has been applied.
  • the hinge is in the closed position.
  • the bracelet 10 comprises an upper arm part 12 and a lower arm part 14.
  • the two arm parts are hinged together at hinge 16 and locked together at lock 18 opposite the hinge.
  • a release button 20 allows the lock to be released to open the bracelet.
  • the lower arm 14 comprises a hinged internal resilient member 21 having hinge side extension 22 towards the hinge 16 and lock side extension 24 towards the lock 18.
  • the hinge side extension 22 has a contoured surface 26 facing the hinge, which interlocks with hinge grabbing member 26.
  • Hinge grabbing member 28 is part of the upper arm part 12 and wraps around hinge 16 when interlocked, allowing the upper arm to rotate about the lower arm.
  • Fig. IB shows the same bracelet in 3D cutaway perspective.
  • Hinge grabbing member 28 has a hinge recess 30 which engages with hinge 16.
  • the hinge recess 30 is open in the radial direction of the bracelet but lower tongue 32 and upper tongue 34 on either side of the recess ensure that there is not enough room for the hinge to be able to exit the hinge recess 30.
  • Lower tongue 32 additionally comprises a downward extension 36 which will be discussed in greater detail in the following figures.
  • the downward extension 36 is shaped to be complementary to the lower part 38 of contoured surface 26.
  • FIGs. 3 A and 3B are simplified diagrams showing the bracelet in the open position. Parts that are the same as in Figs. 1 and 2 are given the same reference numerals and are described again only as needed for further understanding of the embodiment.
  • Upper arm 12 is rotated with respect to the lower arm, causing hinge grabbing member 28 to rotate around hinge 16 until lower tongue downward extension 36 fits into lower contoured part 38.
  • the hinge 16 cannot be removed from the recess 30 because the hinge grabbing member is locked onto contour 26 of arm 32.
  • the contour prevents disengagement of the upper arm 12 and the hinge grabbing member 28 from the lower arm 14 thus ensuring that the hinge grabbing member cannot be released from the hinge.
  • hinge side extension 22 is resilient. As the rotation of the upper bracelet arm 12 exceeds the angle shown in Fig. 3, downward extension 36 slides upwards along the contour lower part 38 until reaching contour bump 40, in doing so pressing down on hinge side extension 22 and levering apart hinge side extension 22 from bracelet upper wall 42.
  • the position at the peak of bump 40 with pressure from extension 22 and wall 42 attempting to close is a position of unstable equilibrium, ensuring that a very light pull from the user is sufficient to cause extension 36 to fall in to the upper trough of contour 26, causing disengagement of hinge 16. Conversely a very light push from the same position would be sufficient to re-engage the hinge.
  • FIG. 5 A and 5B illustrate hinge grabbing member 28 after extension 36 has slid into contour 26 upper trough, consequently moving the hinge grabbing member tangentially upward along the line of the bracelet wall and thus disengaging the hinge 16 with a snap.
  • Fig. 6 shows the upper 12 and lower 14 parts of the bracelet 10 separated. Hinge grabbing member 26 is exposed to view.
  • Figs. 7 A and 7B show how the separated bracelet halves may be put back together.
  • the hinge grabbing member is pushed into the lower bracelet arm at an angle enabling the tongue extension 36 to engage contour 26 upper trough.
  • hinge 16 is not aligned with hinge recess 30.
  • Figs. 8 A and 8B show how the hinge grabbing member is pushed downward from the position shown in Figs. 7A and 7B in order to engage the hinge 16.
  • Tongue extension 36 slides out of contour 26 upper trough over contour bump 40, thus levering open extension 22, and allowing the hinge 16 to slide into the recess 30. Subsequently a slight push snaps the extension 36 into trough 38, trapping the hinge in position.
