Abstract
Description
- The present invention relates to an externally-mounted lock with device for blocking the exit of the bolt and mounting adaptor.
- So-called externally-mounted locks conventionally comprise a case which contains the mechanism for actuating a bolt; the case is adapted to be fixed proximate to the lock stile of a door, usually the door that allows access to a room. The bolt actuation mechanism comprises two bits: one is rotatably supported in the cover of the case on the inner side of the door and the other one is rotatably supported in the back plate of the case in contact with the inner face of the door.
- The first bit is actuated by means of a knob or a cylinder lock (hereinafter referenced to as "inner cylinder" for convenience of description), the plug whereof, like the knob, is rotationally coupled thereto. The second bit is rotationally coupled, by means of a bar that passes through the thickness of the door, to the plug of a cylinder lock which is inserted in an adapted seat of the door, which is referenced to hereinafter as "outer cylinder" since it can be accessed from the outer side of the door.
- Accordingly, whilst the bolt can be actuated from the inside by means of the knob or by means of the key of an inner cylinder, actuation from outside occurs by means of the key of the outer cylinder.
- Considerable complexity in construction and assembly and limited flexibility in use have been observed in locks of this type, owing to the fact that the distance of the case from the edge of the lock stile can vary and that the direction of rotation of the knob (or of the key) must be correlated to the door swinging direction.
- A principal aim of the present invention is therefore to provide an externally-mounted lock which allows to obviate the constructive and installation shortcomings of conventional locks.
- Within the scope of this aim, an object of the present invention is to provide a lock which can offer greater resistance to effraction attempts, particularly against forcing actions applied to the bolt.
- This aim and this object are achieved by an externally-mounted lock, which comprises a case composed of a back plate provided with means for fixing to a door and of a cover which is associated with said back plate and forms a seat for the sliding of a bolt in which an element is articulated, said element having a set of teeth which, by virtue of spring means, is kept engaged with two mutually opposite bits, one bit being supported in said cover and being associated with an internal actuation cylinder or knob, the other bit being supported in said back plate and being connected to an external actuation cylinder, said bits being adapted to produce, as a consequence of the actuation of said knob or of said cylinders, the disengagement of the set of teeth of said element from said bits with a first rotation angle and a lock-turn stroke of said element and of said bolt with a second rotation angle, characterized in that an arm is rigidly coupled to said toothed element and is provided with raised portions which are adapted to engage against corresponding protrusions formed inside said cover, said raised portions being disengageable from said protrusions simultaneously with said teeth when the bits are actuated.
- According to another object of the present invention, the lock is provided, in the back plate, with a secondary plate which allows to use various types of cylinder, presets said lock for right-handed or left-handed mountings (i.e., mountings on right-hinged or left-hinged doors), and allows adjustments in a horizontal direction with respect to the lock stile of the door.

- figures 11a-11d are views of various mounting possibilities of the secondary plate of figure 11.
- With reference to figures 1 to 9, the externally-mounted lock is composed of a
rectangular back plate 1 on which twoparallel ridges sliding surface 4 for abolt 5. A plurality of throughholes 5a are formed in theback plate 1 and are arranged in various manners so as to allow to use studs to protect the outer cylinders and allow various door-mounting possibilities. Twoposts sliding surface 4, at the two corners of theback plate 1 that form the bolt exit side; two respective threadedholes posts ridges - Two
teeth back plate 1 that lies opposite to theposts cover 12, which forms the case of the lock together with theback plate 1. - The sliding
surface 4 affects only part of theback plate 1; aseat 13 is formed in the other part and has a contour which is complementarily shaped with respect to asecondary plate 14, which is fully accommodated in the seat. Holes for the passage of fixing screws, described hereinafter, are formed in thesecondary plate 14. - In particular, two
holes 15 and 16 are formed in the secondary plate 14 (figure 2), andpins 17 and 18 which protrude from the bottom of theseat 13 engage in said holes. - An
opening 19 is formed in theseat 13 at thesecondary plate 14 and its contour duplicates that of theseat 13 and accordingly forms astep 20 for the peripheral resting of thesecondary plate 14. - The
secondary plate 14 has, in an eccentric position, ahole 21 in which thehub 22 of a bit, generally designated by thereference numeral 23, is rotatably supported (figures 6 and 7). - The
hub 22 extends into the opening 19 and is crossed axially by ablind hole 24 having a rectangular cross-section, which is open towards the lower face of theback plate 1. The bar for rotary connection to the plug of the cylinder lock to be installed on the outside of the door is subsequently inserted in theblind hole 24. - A
flange 25 is rigidly coupled to thehub 22, above thesecondary plate 14, and is peripherally provided with arecess 26 shaped like a sector of a circle. Apin 27 protrudes eccentrically from theflange 25 and reaches the centerline plane P of thebolt 5 without extending beyond it. - The
pin 27 is adapted to cooperate with anelement 28 which in practice constitutes an articulated extension of thebolt 5. - The element 28 (figure 3) is substantially U-shaped, with a first arm 29 which has a set of
teeth 30 on the inner edge and, on the outer edge, alug 31 which has afront 32 which is substantially perpendicular to the sliding direction of thebolt 5. - The
second arm 33 of theelement 28 forms, together with the first arm 29, a loop 34 which is open towards theteeth pin 27. - The first arm 29 is joined to the
second arm 33 by an arc-shaped portion 35 which is inserted in aslot 36 of the bolt formed at the end thereof that lies inside the lock and is arranged on the centerline plane P that is co-planar to the bolt. - The
element 28 is articulated to thebolt 5 by means of apin 37 driven through the arc-shaped portion 35. - The second arm 34 has, on the outer edge, two raised
portions 38, each whereof has afront 39 which protrudes concentrically with respect to thepin 37. - Hollows remain between the raised
portions 38, and theprotrusions cover 12, at the level of theelement 28, engage between said hollows. - As shown more clearly by figures 4 and 5, the
cover 12 is shaped like a prism-like box and comprises: twolongitudinal walls protrusions transverse walls closure wall 46 which, together with the walls 42-45, encloses the compartment for containing the elements of the lock. - An
opening 47 is formed in thetransverse wall 44 that constitutes the front wall; thebolt 5 protrudes outside through the opening. - The upper edge of the
opening 47 is aligned with aplane 48 formed on the inner face of thewall 46. - The
plane 48 is delimited by tworidges opening 47. Theplane 48 and theridges surface 4 and theridges back plate 1, the sliding seat of thebolt 5. - The
cover 12 is fixed to theback plate 1 by engaging theteeth indents transverse wall 45 and by inserting theposts recesses front wall 44 byflaps walls holes front wall 44, to the sides of theopening 47, and two screws for locking thecover 12 to theback plate 1 are guided through said holes. - A
circular recess 59 is formed outside thewall 46 and continues centrally inwards with a tubular portion 60. - A second bit 61 (figures 1, 8, and 9) can rotate in the tubular portion 60 and is composed of a
disk 62, from which twoaxial pins - The
disk 62 has acavity 65 which is elongated diametrically between thepins slots 65a are formed in the bottom of thecavity 65 and are shaped like an arc concentrically to the axis of thedisk 62. Two ridges 65b are engaged in theslots 65a and fixed therein by folding their edges; the ridges are formed frontally in ahub 66, which is thus rotationally coupled to thedisk 62. Thehub 66 protrudes outwards through therecess 59, and aknob 67 is rigidly coupled thereto. - The
hub 66 can rotate in abush 68 which has acollar 69 that is recessed in a hollow 70 of therecess 59 and is retained by a washer 71 which rests on thecollar 69 and is fixed by screws which engage the bottom of therecess 59. - The
pins element 28 to engage between theteeth 30 of the arm 29. - The described lock is completed by a
spring 72 which is accommodated in ahole 73 formed in thebolt 5 and leading into theslot 36. Thespring 72 acts on achamfered portion 74 formed in the peripheral region of the arc-shaped portion 35 eccentrically with respect to thepin 37. In this manner, theelement 38 is turned, causing the engagement of thepins teeth 30 of the arm 29. - The operation of the described lock is as follows.
- When inactive, with the bolt engaged or disengaged, the action of the
spring 72 causes the oscillation of theelement 28 towards thewall 42 of the cover and therefore the engagement of the raisedportions 38 between theprotrusions 40 of the cover. - In this situation, any force applied to the bolt in the direction in which it retracts into the case is neutralized by the abutment of the raised
portions 38 against theprotrusions 42 and is therefore not discharged exclusively onto thepins - It should also be noted that the
front 39 of the raisedportions 38, by being perpendicular to the radius that passes through thepin 37, prevents any possibility of mutual jamming of the raisedportions 38 and of theprotrusions 42 and therefore prevents the occurrence of friction which might compromise the disengagement of theelement 28 when the lock is operated. By actuating thebit 62 through theknob 66, or thebit 23 by means of an external key, the consequent rotation of thepins spring 72 which contrasts the lifting of the arm 29, which is required in order to first disengage the raisedportions 38 from theprotrusions 40 and then move the bolt so that it protrudes from the case or retracts thereinto. It should also be noted that when the bolt is fully outside the lock, i.e., when it engages the respective selvage, thelug 32 rests on thepost 7 and prevents theelement 28 from rotating and prevents the raisedportions 38 from disengaging from theprotrusions 40 if thebolt 5 is forced so as to retract into thecase - The fact is also important that the wear that affects the
pins portions 38 over time does not compromise the efficiency of the lock. - Any increase in play caused by wear is in fact compensated for automatically by the
spring 72 that acts on theelement 28. - A substantial prerogative of the present invention is constituted by the fact that the
hole 21 for supporting thehub 23 in thesecondary plate 14 is offset with respect to the center thereof, in the bolt sliding direction, and that two pairs ofholes holes 75 has, with respect to the axis D that runs through theholes 15 and 16, a distance (a) that is greater than the distance (b) of the pair ofholes 76 from said axis. This arrangement of theholes - For example, figure 10 illustrates the
back plate 1 of a lock which is mounted on a left-hinged door, whereas figures 10a-10d illustrate four different possibilities of mounting thesecondary plate 14, which allow to mount a matching number of external cylinders. - Figures 11 and 11a-11d illustrate a similar situation for a right-hinged door.
- It should be noted that the plate has
recesses 77 along two sides to allow the passage of the screws for fixing theback plate 1 to the door. Likewise, therecess 26 of thebit 23 allows the screws to pass through theholes - The described invention is susceptible of numerous modifications and variations, all of which are within the scope of the same inventive concept. For example, the
internal bit 61 can be actuated by a pin-tumbler cylinder accommodated in a seat of theknob 67, which in this case is rigidly coupled to thecover 12. - Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly such reference signs do not have any limiting effect on the interpretation of each element identified by way of example by such reference signs.
