  • the edges of the wedge plate are beveled and the internal edges of the lock ring are beveled as well in order to allow good engagement of the surfaces facing each other.
  • the edges on the internal periphery of the lock ring are advantageously beveled in such a direction so that when the lock ring is rotated to engage with the wedge plate, the lock ring pressed the wedge plate towards the back plate of the lock base, which forces the wedge plate to rest on the guiding elements on the back plate which further locks the wedge plate in place.
  • the rotation of the lock ring can be implemented, for example, using springs arranged in a pushing or a pulling configuration.
  • the releasing of the mechanism can be done simply by attaching a piece of cord to the lock ring which cord can then be drawn by the user to rotate the lock ring to an open position.

  • the lock base preferably comprises a mechanism that keeps the lock ring in an open position until the wedge plate is inserted into the lock plate.
  • this lock ring latch mechanism can be implemented using a lever which keeps the lock ring in an open position until the wedge plate is inserted. By pressing the lever down and away from the lock ring, the lock ring is released to rotate and lock the wedge plate in place.
  • This is advantageous, since if there were only one lever holding the lock ring in place, it would be possible to insert the wedge plate at an angle into the lock base so that the lock ring would be released before the wedge plate is fully inserted into the lock base, which would cause the lock ring and the wedge plate to jam at an incorrect position.

  • Figure 2a illustrates the mechanism just after insertion of the wedge plate 120 before turning of the lock ring.
  • Figure 2b When the wedge plate 110 is inserted into the lock base, the lock ring is released. It rotates to the closed position which is illustrated in Figure 2b.
  • Figure 2b it can be seen that edges of the wedge plate 110 are engaged with the edge of the lock ring 130, therefore, locking the wedge plate into its position. In this locked position, this wedge plate cannot rotate because of the guiding pins or guiding shapes of the base plate. Also the wedge plate cannot move out of the lock base. It is prevented from moving in that direction by the lock ring.
  • Figures 2a and 2b also illustrates springs 210, which cause the lock ring to rotate and lock the wedge plate in place when the lock ring is released.
  • Figure 2 A and 2B also illustrate such an embodiment of the invention in which the wedge plate can be inserted into the lock base in eight different angles.
  • the wedge plate has eight wedges and the lock base has corresponding recesses. Consequently, with this number of wedges, the possible attaching angles for the wedge plate are at 45 degree intervals. By increasing the number of wedges, the number of possible attachment angles can be increased.
  • the basic role of the springs 210 is to rotate the locking ring 130 when the locking ring is released.
  • the second reason why the spring elements 210 are very advantageous have in an embodiment of the invention is that they keep pushing the lock ring even when the wedge plate 110 is inserted in the lock base. From this follows that the structure is self-tightening, since any vibration or any shocks that the attachment mechanism endures might shake the wedge plate a little bit, and if that happens, the springs 210 push the lock ring even further, thus tightening the grip of the lock ring on the wedge plate.
  • FIGS. 2A and 2B also illustrate a cord 135 which the user can use to release the lock ring 130 by pulling the cord 135, therefore rotating the lock ring into the open position so that it releases the wedge plate and allows the removal of the wedge plate from the locking base.

  • Lever 142 is pushed by spring 143.
  • the lever When the lever is in the raised position and in the slot of the lock ring, it locks the lock in place, inhibiting the rotation of the lock ring.
  • the wedge plate When the wedge plate is inserted into the lock base, the wedge plate presses down the lever 142, thus removing it from the slot in the lock ring 130. Consequently the lock ring 130 is able to rotate into another position, as shown in figure 3B.
  • the lever 142 is pressed down towards the base plate and the lock ring has in figure 3B rotated slightly so that the lever is out of the slot 145 in the lock ring 130. Therefore the lock ring is able to rotate until it meets with the wedges of the wedge plate, thus locking the wedge plate into place.

  • the user can push the lock ring latch mechanism into a position where the attachment mechanism is open and able to be locked, but the lock ring latch mechanism is not engaged, so that the lock ring is operable and will close when the user puts the wedge plate into the attachment mechanism.

  • a lock ring latch mechanism has several benefits. For example, when the attachment mechanism is locked, this lock ring latch mechanism makes certain that the attachment mechanism stays locked, no matter what kind of loads, vibration, push and pull the mechanism is subjected to. Since the lock ring latch mechanism locks the lock ring into place, it cannot rotate, irrespective of what kind of force the hold mechanism is subjected to. Also when the attachment mechanism is being opened, this lock ring latch mechanism can lock the lock ring into an open position, so that it stays open while the user lifts whatever is attached to the wedge plate.
  • the attachment mechanism is used for attaching a heavy object, say, for example a table top to a support.

  • Figure 6A, 6B, 6C, and 6D also illustrate an embodiment where the attachment mechanism has a locking hole 650, where the user can, for example, put a conventional padlock to prevent removal of whichever object is attached using the attachment mechanism. Any object inserted into the lock hole 650 prevents the movement of the knob 610 from either of the open or closed positions to the other, therefore, any object put into the locking hole 650 effectively disables the operation of the attachment mechanism until that object is removed from the locking hole 650.
