Definitions

  • This invention relates to a device for hooking and unhooking keys carried by a key holder.
  • One type of presently available key holder comprises as its key support element a rigid ring, of which a portion is open and which rotates in a slot provided in the key holder body.
  • a slidable button which is rigid with a tooth. By sliding the button with a finger, the tooth either becomes inserted into or withdraws from the slot.
  • the button is pushed in such a direction that the tooth enters the open portion, so preventing further rotation of the ring.
  • the tooth leaves the slot and returns to its seat, so enabling the ring to rotate in order to move its open portion to the outside for adding or replacing keys.
  • the invention proposes to simplify this design by replacing the tooth and button with a resilient element which spontaneously engages in the open portion, so preventing accidental rotation of the ring, but for which a manually applied force of no great strength is sufficient to oppose the action of the resilient element and allow the ring to rotate.
  • the resilient element gives definitely improved reliability and life to the device, and the keys are held in a secure manner and can be unhooked only by intentional manual action but not accidentally.
  • a device for hooking and unhooking keys carried by a key holder comprising a key holder body and a ring containing an open portion sufficiently large to enable keys to be hooked on to and unhooked from the ring, the ring rotating in a slot of circular arc configuration provided within the body and of length such as to contain in its interior a ring portion of greater length than the open ring portion, characterised in that a portion of the slot is constricted by an arcuate flat spring which presses on to the ring, and of which the curvature is such that when in its rest positioA it lies between the edges of the open portion in order to prevent accidental rotation of the ring, the elasticity of the spring being such as to enable it to deflect under the force exerted by the manual rotation of the ring, thus withdrawing from the open portion.
  • a ring 11 is provided with an open portion 12 and slides in a slot 13 provided in the body 10.
  • the cross-section of the slot 13 is slightly greater than that of the ring, and has the same curvature so that the ring can slide freely inside it.
  • the slot 13 enlarges on one side to form a cavity 14, in which two notches 16 are provided, separated from the slot 13 by walls 15.
  • Suitable spacers 20 retain the ends 17 of the spring 18 in the notches 16, to enable them to slide axially with slight slack so that the spring can deform, but not to translate parallel to itself.
  • the open portion 12 of the ring 11 When in the position shown in Figure 1 and by the full lines in Figure 4, the open portion 12 of the ring 11 contains in its interior the vertex 19 of the spring 18, which prevents rotation of the ring because any small rotational movements of the ring in one direction or the other cause the edges of the open portion 12 to make contact with the spring.
  • the body 10 is advantageously formed from two half-body portions, glued, screwed or otherwise fixed together in order to form between them the slot 13 and compartment 14 for containing the various members of the device.
