Abstract
Description
- The present invention relates to a spring-latch and bolt lock with emergency opening device.
- Door locks are currently known which have a spring-latch, which can be opened by means of an adapted handle, and a locking bolt actuated by a key. In some cases, for example in the case of hotels and the like, it is convenient to allow the door to open rapidly from one side, i.e. merely by means of the handle and without using the key. This need arises from evident safety reasons, since it must be possible to easily leave the room, in particular in case of danger, while preserving the lock function of preventing access from outside.
- Locks have therefore been devised which have a single-side opening device constituted by a lever system which opens the bolt upon the actuation of the knob arranged on the inside. In particular, said lever system essentially comprises a first lever which releases the bolt and a second lever which controls the opening movement of the bolt itself.
- Said locks are furthermore generally provided with a safety device adapted to lock the spring-latch in closure position. This device is deactivated by the actuation of the handle or by the actuation of the key which opens the bolt.
- The locks of the above described kind are not free from disadvantages. In particular, the structural complication of the device for the release and quick opening of the bolt, which is the cause of possible malfunctions, is observed, together with the poor reliability of the spring-latch safety device.
- During mounting of the lock, the rotation of the spring-latch about its own axis is furthermore difficult; this rotation is required to adapt the lock to the different door sides on which it is applied.
- The aim of the present invention is to provide a spring-latch and bolt lock which allows to perform in a simplified and surely functional manner the quick opening of the bolt by actuating the spring-latch actuation handle.
- An object of the present invention is to provide a spring-latch and bolt lock which has a spring-latch locking device which is simple in concept and safely reliable in operation.
- A further object of the present invention is to provide a spring-latch and bolt lock which allows to easily orientate the spring-latch itself.
- This aim and these objects are achieved, according to the invention, by the present spring-latch and bolt lock with emergency opening device as defined in the appended claims.
- The details of the invention will become apparent from the detailed description of a preferred embodiment of the spring-latch and bolt lock with emergency opening device, illustrated only by way of non-limitative example in the accompanying drawings, wherein:
- figure 1 is a longitudinal sectional view of the lock according to the invention in closed position;
- figure 2 is a sectional detail view, taken along plane II of figure 1, of the spring-latch orientation device;
- figure 3 is a partially sectional front view of said spring-latch orientation device.
- With reference to the above figures, 1 indicates the box of the lock according to the invention, which is mounted in the
recess 2 of adoor 3; saidbox 1 has afront plate 4 which closes therecess 2 and allows the lock to be fixed to the door. - The lock has a spring-
latch 5 and abolt 6 which are adapted to protrude from thebox 1 through theplate 4 to engage, in closure position, respective seats 7 and 8 provided in the doorjamb; the seats 7, 8 face corresponding openings formed in aplate 10 applied to the doorjamb. - The spring-
latch 5 is provided with astem 11 on which a return helical spring 12 for the spring-latch is mounted; the spring 12 acts, at its opposite ends, on anabutment 13 rigid with the box and on aring 14 rigid with thestem 11. Asmall plate 15 is fixed to the free end of thestem 11, and an opening element, generally indicated by 16, is adapted to act thereon. - The spring-
latch 5 can be actuated by an adapted handle, not illustrated in the drawings, which is engaged in a square-holedpivot 17. Theopening element 16 is mounted on thepivot 17 and is rotatable together with said handle. - The
opening element 16 comprises a series of variously shaped rings mounted side by side on thepivot 17. More in particular, said series of rings includes a pair of outer rings, which are mutually identical and are both indicated by 18, and anintermediate ring 19. - The
outer rings 18 define respective projections forming theprongs 18a of a sort of fork which embraces thestem 11 of the spring-latch 5 so as to act on theplate 15 of said stem; in the closure position of the spring-latch, said fork is kept resting on the fixedabutment 13. - The
outer rings 18 furthermore definerespective expansions 18b which are substantially angled at 90° with respect to theprongs 18a in the handle opening direction of rotation A. Only theexpansion 18b of the ring which is nearer to the observer has been indicated in figure 1 in order to illustrate theintermediate ring 19. - The
expansions 18b are adapted to act on ahelical return spring 20 of the handle; saidspring 20 rests on anabutment 21 which is fixed to thebox 1. - The
bolt 6 can be actuated by a known key device, theseat 22 whereof is illustrated in the drawings. Thebolt 6 is provided with a prism-shaped tang 23 which is slidably guided by the engagement of aslot 24 of the tang with asquare pivot 25 fixed to thebox 1. Thebolt 6 is adapted to be locked in the closed position by the engagement of saidsquare pivot 25 with atooth 26a of alocking element 26 supported by said bolt. Theelement 26 is biased by aspring 27 which acts on a wing 26b of said element and is intended to be released by the key opening device and by theopening element 16. It should be noted that theelement 26 is guided transversely to thetang 23 by the engagement of a tooth 26c and of the wing 26b in correspondent slots of the tang. - The lock is provided with a device for the quick release and opening of the bolt, generally indicated by 28. Said device has an
opening lever 29 which has afulcrum 30 rigid with thebox 1 and can be angularly rotated by theopening element 16 of the spring-latch by means of the related handle. For this purpose, theouter rings 18 of theelement 16 define respective teeth 18c adapted to act on acorresponding flap 29a of the lever. - The
lever 29 defines, in a center position, a lug 29b which engages apawl 31 for the release of thebolt 6. Saidpawl 31 is pivoted to thetang 23 of the bolt at apivot 32 and is adapted to engage, by means of atooth 31a defined by an undercut, the wing 26b of thelocking element 26, so as to act in contrast with thespring 27. - The
pawl 31 normally rests on the lug 29b with a front edge 33 thereof. Thetang 23 of the bolt is furthermore provided with atransverse pivot 34 which is slidable in aslot 35 formed at one end of areturn lever 36. Thereturn lever 36 is articulated, at the opposite end, at 37, to a wing 19a of theintermediate ring 19 of theopening element 16. - The opposite ends of a
spring 38, wound around thepivot 17 of the handle, are respectively engaged to the teeth 18c of theouter rings 18 and the wing 19a of theintermediate ring 19 of theelement 16. - The rotation of the handle in the direction indicated by the arrow A therefore causes the retraction of the spring-
latch 5 and the rotation of thelever 29 about thefulcrum 30 for opening thebolt 6. In a first portion of said rotation, theopening lever 29 releases the bolt; thelever 29 in fact causes the rotation of thepawl 31, which raises thebolt locking element 26, compressing thespring 27. - In a second portion of its rotation, the
lever 29 opens thebolt 6, pushing with its lower end against the wing 26b of theelement 26 which conveniently protrudes from the face of thetang 23 and moving theelements 26 and thebolt 6 to the opened position (to the right in figure 1). To summarize, the actuation of the knob, which is conveniently arranged on the side of the door directed toward the inside of the room, allows to open the door immediately even when the bolt is locked. - Vice versa, the return of the handle occurs under the thrust of the
spring 20. - The
return lever 36 has the important function of opening the spring-latch 5, acting on theopening element 16, if the bolt is opened by means of the key. This obviously allows not to mount the handle on the outer side of the door, so as to allow opening only by means of said key. - The lock has a safety device which is adapted to lock the spring-latch and is generally indicated by 39. Said
safety device 39 has alocking lever 40 preventing shifting of the spring-latch 5 and hinged at afulcrum 41 on thebox 1. - The
locking lever 40 can be angularly rotated by the spring-latch opening element 16. For this purpose, theintermediate ring 19 of theelement 6 defines a shoulder 19b which engages a lug 40a of thelever 40; the engagement of the shoulder 19b with thelever 40 is ensured by a spring 42 which is mounted on thefulcrum 41 and engages, with its opposite ends, the fixedabutment 13 and a flap 40b of said lever. Thering 19 furthermore defines anexpansion 19c which is arranged between theprongs 18a of theouter rings 18 of theelement 16 and acts on theplate 15. Thering 19 furthermore has atab 19d which is folded downward (in the drawing) and rigidly associates theinner ring 19 with theouter rings 18 when theelement 16 is rotated by the handle. - The
locking lever 40 is controlled by anelement 43 for sensing the closure of thedoor 9; said element is frontally rounded and beveled like the spring-latch 5. Saidsensor 43 is axially movable under the thrust of aspring 44 guided in a seat 43a provided in the body of said sensor; thespring 44 reacts on a fixedabutment 45 of thebox 1. Thesensor 43 can protrude from thebox 1, through theplate 4, and retract in the door closure position when it abuts against thefront plate 10 of the doorjamb. Thesensor 43 is guided in its movements by theplate 4 and theabutment 45. - A
transmission lever 47 is articulated at 46 to thesensor element 43 and is adapted to release thelocking lever 40 in the door opening configuration. The transmission lever 47 centrally abuts against aninternal wing 48 of thebox 1 and engages in turn, at its end, the flap 40b of thelocking lever 40 on the side opposite to the spring 42. - The
locking lever 40 prevents the movement of the spring-latch 5 when the door is closed, but is brought in an ineffective position by the rotation of theopening element 16 in direction A. When the door is open, the outward movement of thesensor 43 caused by thespring 44 holds thelocking lever 40 in a position in which it does not intercept the free sliding of the spring-latch 5. - The lock is furthermore provided with a spring-latch orientation device, generally indicated by the
reference numeral 49. Said orientation device has aslider element 50 mounted on therear wall 1a of thebox 1 in front of the spring-latch 5 and slidable along a vertical direction (in the drawing). Theslider 50 is guided by a transverse pivot 51 rigid therewith in aslot 52 of the box and can be actuated from the outside of the box by means of atooth 53. - The
slider 50 has anopening 54 adapted to be aligned with thestem 11 of the spring-latch, so as to allow the axial rotation thereof. For this purpose, theslider 50 is movable between said alignment position and an off-center position of theopening 54, said positions being defined by the engagement of a pair ofnotches 55 of said slider with correspondingprotrusions 56 formed on therear wall 1a of the box which is opposite to thefront plate 4. - By moving the
slider 50 to said position of alignment of thestem 11 with theopening 54, it is possible to move the spring-latch 5 inside thebox 1, inserting the end of thestem 11 into said opening. The spring-latch can therefore be rotated axially through theopening 57 provided in the box. - Instead, when the
slider 50 is in the off-centered position, i.e. in the normal condition of use of the lock, theslider 50 acts as stop element for the axial sliding of thestem 11, preventing the accidental extraction of the spring-latch from its seat. - A substantial advantage of the present invention is constituted by the fact that the elements, by virtue of their arrangement, allow to leave free large regions of the walls which laterally delimit the
box 1. This allows to provide, in said regions, holes through which through screws are driven; said screws also traverse the thickness of the door and can retain the plates of the handles. - In the practical embodiment of the invention, the materials employed, as well as the shape and dimensions, can be any according to the requirements.
- 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 scope of each element identified by way of example by such reference signs.
