  • a second knob device is illustrated, generally indicated with 1OB, which is adapted to be applied to the above-mentioned door on the inner side of the same, coupling with the previous knob device 1OA, and intended to also operate the bolt of the same door.
  • the knob device 1OB has a lot of components which are identical to those of the knob device 1OA; such device 1OB identical components are indicated with the same reference numbers which have been used for the device 1OA.
  • the device 1OB has, unlike the device 1OA lock
  • the device 1OB is provided with, instead of the hollow pin 18 of device 1OA, a solid pin 28 which is adapted to be male-female coupled precisely to the hollow pin 18.
  • the device 1OB under-key which is indicated with 19B, also has some small differences relative to the device 1OA under-key 19A.
  • the under-key 19A has a projecting guide 3OA along the longitudinal axis, and two opposite shelves 3IA on the sides thereof. Furthermore, two opposite elastic hooks 32A extend from the projecting guide 3OA sides. An elastic detent 33A is provided on the opposite part relative to the guide 3OA along the longitudinal axis.
  • the key 25 has two opposite longitudinal tongues 34, two opposite ribbed shelves 35, two opposite angular projections 36, and a transversal projection 37 in the inner part thereof.
  • the key 25 is caused to slide on the under-key 19A and, from a fixed point on during such travel, the key 25 tongues 34 slide on the under-key 19A guide 3OA, and the key 25 shelves 35 slide on the under-key 19A shelves 3 IA; at the end of the travel, the under-key 19A hooks 32A elastically snap-couple the angular key 25 projections 36, and the under-key 19A detent 33A elastically snap-abuts against the key 25 projection 37.
  • the under-key 19A is also provided, at the opposite part relative to the guide 3OA, with two projecting teeth 38A which, as shown in the Figs. 1, 2, abut in two corresponding recesses 39 which are obtained in the hollow body 11.
  • the knob device 1OB under-key 19B has the same members which have noted above for the knob device 1OA under-key 19A, which are indicated with the same numbers followed by the letter B.
  • the elastic detent which was present in the under-key 19A is omitted in the under-key 19B.
  • the under-key 19B hooks 32B have two sloped planes 40B at the ends thereof, which are absent in the under-key 19A.
  • Such mechanism comprises two overlapped arms 40 which are hinged on a pin 41, so as to have a divaricating and overlapping movement.
  • Each arm 40 has, essentially at the pin 41, a contact side appendix 42, and a coupling vertical appendix 43.
  • Respective lever 14 contact portions 44 act upon the contact appendixes 42.
  • a spring 45 is anchored to the coupling appendixes 43.
  • Fig. 10 The assembling of the knob devices 1OA and 1OB on the door is illustrated in Fig. 10.
  • Such door is indicated with 100, and the bolt is housed therein, which is indicated with 101 and which slides in the door and is kept in a projecting position from the door, opposing an elastic force.
  • the knob devices are secured one to the other by means of screws 29, mounted on the device 10B, which act as to be screwed in the device 1OA special threaded holes.
  • Aligning during the assembling of the devices 1OA and 1OB is achieved by the male-female coupling between device 1OA hollow pin 18 and device 1OB solid pin 28.
  • the lock 16 couples to the locking mechanism 26 (Fig. 3) through the rod 17.
  • each knob device arms 40 fit in a bolt 101 special seat 102; the arms 40 of the two devices are offset in the height thereof, so that each is able to be fitted into such bolt 101 seat 102.
  • the functioning of the knob devices 1OA and 1OB is as follows, with particular reference to Fig. 11.
  • the under-key 19A rotation around the pins 22 thereof (which are visible in the Figs. 1, 2) is obtained.
  • the under-key 19A rotation determines the lever 14 rotation around the pins 15 thereof, by means of the contact between under-key 19 lower projecting ribs 45 and a lever 14 upper portion 46.
  • the lever 14 acts on the arms 40 appendixes 42 with the contact portions 44 thereof, thus determining the same arms divarication, and hence the bolt 101 displacement inside the door in order to open the same under the effect of one of the two arms 40 on a seat 102 wall.
  • the other of the two arms 40 would act on the seat 102 opposite wall.
  • the rod 17 rotation is caused, which rod travels to such a position as to interfere with one of the two contact appendixes 42, so as to prevent the arms 40 from opening.
  • the same effect is achieved when the push button 27 of the knob device 1OB locking mechanism 26 is pushed.
  • the lock 16 is in the locking position, also the push button 27 is locked .
  • the under-key 19A or 19B which under-key constitutes a further lever arm, the stress exerted to control the door opening is reduced. It shall be noted that the under-key has a lever arm extending essentially on the entire knob device length.
  • the key 25, which covers the entire knob device upper part, allows having a large surface where pressure can be exerted.
  • the coupling detent 33A presence, and the absence of the sloped planes on the hooks 32A does not allow easily unfastening the under-key 19A from the key 25, so as to avoid illegal opening operations from the door external side when it is closed, trying to access the knob device inner cinematic motions.
  • the knob device 1OB which is mounted on the door internal side, the presence of the sloped planes 4OB on the hooks 32B, and the absence of the coupling detent allow easily unfastening the under-key 19B from the key 25, with a simple clamping tool acting upon the sloped planes in order to move the hooks away from the angular projections 36 and to withdraw the key .
  • the configuration of the several components may vary as a function of the needs .
  • knob devices that have been described and illustrated herein can be applied to any type of lock.
