- the embodiment functions as both a latch and bolt.
- FIG. 2 shows double action cylinder locks with an inner doorknob and outer key, a practical variation of the embodiment of FIG. 1.
- FIG. 3 shows the double action cylinder lock cut away at its doorknobs (36) and (37), the cut-away casing (35) showing the support for the inner doorknob (15), the principal body (17), the key-groove (27) for the bolt casing (22), orifice (28) for the engaging of the connecting rod (19), and support. for the outer doorknob (30).
- FIG. 4 shows in its sectioned form the inner doorknob support (15), the sliding bolt (4), the inner knob spring (6), the checkpiece (16) of the doorknob (36), which checkpiece enters into play when the doorknob (36) is pulled outwards, the eccentric piece (8) fixed with the screw (10), which is designed so that when it is well tightened the eccentric piece turns freely.
- FIG. 4 details are shown of the principal body (17) on which the shank (31) acts, the sleeve (12) in which the key cylinder (11) is fitted, the key cylinder (11) the bushing 18, the key (14), the combination (13), the cotter fixed to the key cylinder (11) whose mission is that of moving the sliding bolt (4) when the lock operates with the key.
- the cutter,(5) is also the checkpiece for the latch when the two doorknobs function in combination with the sliding bolt in the latch mode of operation.
- FIG. 5 (section through V-V of FIG. 4): sliding bolt (4), passageway (34) for the travel of the inner doorknob, spring (3) of the thumb latch, recess (33) where the spring (3) is situated.
- FIG. 6 (section through VIVI of FIG. 4): sliding bolt (4), the eccentric piece (8) with itsrecess for shank (31) rotatable by the outer doorknob (37), coupling bolt (7) which is joined to the connecting rod (19) which moves the bar (2), the screw (10) for fixing the eccentric piece.
- FIG. 7 (section through VII-VII of FIG. 4): sliding bolt (4), coupling bolt (7), cotter (5) fixed to the cylinder (11) by a pin, shank (31) of the outer doorknob support, slot (32) for the travel of the latter.
- FIG. 8 shows the whole of the mechanism that moves the bar: the bar (2), the casing (22) for the bar the pivot pin (21) for connecting rod (19), the spring (20) for the connecting rod (19), the connecting rod (19), the coupling bolt (7) for the connecting rod (19), the sliding bolt (4) fixed to to the support of the inner doorknob, the eccentric piece (8), the screw (10) for fixing the latter.
- FIG. 9 shows the support (30) of the outer doorknob (37) and the shank (31).
- the assembly of all the elements, in the double action cylinder lock is effected in the following manner: there is introduced under pressure the sleeve (12) into the outer doorknob support (30); in the recess between the sleeve (12) and the doorknob (37) the shank (31) is also introduced under pressure.
- This complex of doorknob, sleeve and shank turns freely between the head of the sleeve (12) and the principal body (17): there is thus achieved the free rotation of the outer doorknob provided that it is not locked with a key, as will be explained later.
- FIG. 2 shows the double action cylinder lock, in an alternative embodiment of the invention, showing an inner doorknob and outer key.
- FIGS. 10 and 11, and the sections shown in FIGS. 12, 13 and 14 taken, along the axes XII-XII, XIII-XIII and XIVXIV of FIG. 7, represent the components and situation of the pieces that form the double action cylinder lock, in accordance with this embodiment. Since they are pieces common to the double action cylinder lock detailed in FIG. 1, and designated by the same numbers, they are not repeated in this paragraph. The only element that varies is the eccentric piece (9) there being eliminated in this embodiment the outer doorknob (37) and the shank (31).
- FIG. 16 shows the complex of the bar and the connecting rod. There can be seen in this Figure the emergence of the bar (2) in a normal latch position (position 1) where rotation of either inner or outer doorknob (or key) will retract bar (2) substantially into the bar case (22). FIG. 16 also shows the extended position (position 2) of bar (2) where the bar (2) acts as a dead bolt.
- the doorknob (36) is pulled slightly outwards and turned through a second sector extending beyond the limits of the first sector and in a direction opposite to the direction the doorknob (36) is turned to retract bar (2) within case (20).
- the operation of pulling out is effected so that the sliding bolt (4) will pass above (axially to the left in FIG. 4) the fixed cotter (5) when it is operated by the interior of the double action cylinder lock. In this poistion, the cotter (5) prevents movement of the sliding bolt (4) by rotation of the outer doorknob (37).
- the latch can be concealed in the case (22) that supports it by effecting corresponding rotation of the doorknob (37 leaving the door free. This operation can be effected since the doorknob is linked by means of the shank (31) with the eccentric piece (8) which is joined to the connecting rod (19) of the bar.
- the bar is situated in the closed position; the fixing screw is then withdrawn, and subsequently the casing (22) of the bar is withdrawn until the cotter (26) emerges from the key groove (27); the lock (doorknob and casing) is then displaced towards the interior of the room, until the connecting rod (19) is freed from the bolt (7), which is shorther than the width of the orifice (28); finally, on the connecting rod remaining free, there is effected the total extraction of the block formed by the casing of the bar, the bar and the connecting rod.
- This operation of dismantling is carried out in a maximum time of fifteen seconds.
- a double action cylinder lock of the type applicable to doors and similar structures said lock having at least one doorknob, a doorknob actuator assembly, and a bar slideable in a casing, and wherein said doorknob actuator assembly is fitted for insertion into an opening in the plane of the door or similar structure and said bar and bar casing are fitted for insertion into an orifice through the edge of the door or similar structure, said orifice meeting with and oriented normal to said opening, the improvement in which:
