Field of the invention
[0002] This invention aims at being applied in mortise locks, particularly in those locks
that are bound to be crammed into doors or other locking elements constructed on the
base of metallic sections, what is commonly known as metallic joinery.
[0003] This invention refers to a mechanism of automatic withdrawal of an articulated latch
which is acting in combination with an anti-panic withdrawal mechanism of the locking
lever.
State-of-the-art
[0004] By its proper nature the joinery based on metallic sections is suffering from a notable
lack of space in respect of cramming the casing of the lock into the reduced size
of the normalized sections used for this purpose.
[0005] On the other hand, as un undesired consequence of the aforesaid, the locks used for
this purpose are of simple and cheap constitution; this means that their actuation
in regard of functioning modes, applied adaptability and safety conditions is very
limited, as it turns out to be quite complicated to insert a mechanism in such a reduced
space that offers different alternatives of functioning and application, as larger
locks, which additionally should be cheap. It is most common that in this class of
locks exist different designs, each of them with determined characteristics that include
very limited actuations and some shortcomings that can be found in other designs of
the same class, but which are not directly interchangeable. One has to choose one
or the other, which is sometimes conditional to the specific section used in each
case among the different ones that are normalized. Among the most necessary applications
in a lock considered as conventional are: It should have a simple constitution, its
functioning should be reliable, it should have safety features that offer a reasonable
inviolability in regard of the most common techniques of fraudulent opening, it should
have an anti-panic feature (allows to open from the inside in any case by actuating
only the inner handle), and it should be simply adaptable for doors opening to the
right or the left.
[0006] The present invention also proposes that a radial extension of the follower supplement
is attached under a vertical carriage that incorporates a vertical arm reaching through
the supporting element of the articulated latch, the vertical arm of which has a superior
protrusion in a position corresponding to a state of rigidity of the articulated latch.
In this respect claims 2 to 6 precise the following: That the vertical arm has an
inferior protrusion the ascending vertical run of which towards the articulated latch
is superior to the vertical arm and the brackets of the supporting element; that the
inferior protrusion is driven by the vertical carriage; that a vertical spring is
intercalated between the inferior protrusion of the vertical arm and the supporting
element of the articulated latch; that the vertical arm has a lowered position corresponding
to a relaxed state of the vertical spring and that the superior protrusion remains
inserted in a free space between the head and the supporting element of the articulated
latch; and that the vertical arm has an elevated position corresponding to a compressed
state of the vertical spring and that the superior protrusion remains outside of the
free space between the head and the supporting element of the articulated latch.
[0007] Corresponding to these means, in respect to the lowered position of the vertical
arm in which its superior protrusion stays inserted in the free space between the
head and the supporting element of the articulated latch it results that in its posterior
part or the part opposed to the back of said head said superior protrusion of the
vertical arm remains abutted against the flat frontal face of the brackets of the
supporting element; which can bring about that during the maneuver of inserting and
withdrawing the superior protrusion into the free space a friction occurs that is
detrimental to a larger smoothness of it.
Description of the invention and advantages
[0008] At this state, by means of the present invention a casing for locking for cramming
in joinery on the basis of metallic sections is proposed that - as will be exposed
in the following - is designed to be able to accommodate locking mechanisms with anti-panic
function, with the ability of simple adaptation to right-hand and left-hand doors,
with safety anti-violation devices by using different embodiments of levers for locking
and latches, and for all of that using a reduced number of pieces integrated into
simple constructions, and functioning reliably.
[0009] For this purpose, taking as references superior, inferior, anterior and posterior
as corresponding to the working position of the lock built in a door, the casing according
to the invention consists of a casing body, a lateral cover and of a front; the body
is delimited by a lateral wall, a superior wall, an inferior wall and a posterior
wall; the lateral wall has openings for the first bearing, second bearing and third
bearing, respectively, as well as a vertical rip and a retraction appearing at its
interior face, a vertical window and a horizontal groove; paired with those of the
body the cover has a first bearing, second bearing and third bearing, respectively,
and paired with the vertical window and the horizontal groove of the body this cover
has a vertical window and a horizontal groove. The pairs of first bearings, second
bearings and third bearings have diameters reciprocal to those of the shaft lugs corresponding
to an assembly of follower and follower supplement, and to a first toothed rotatory
lever and a second toothed rotatory lever; the horizontal groove of the lateral wall
is larger than the horizontal groove of the cover and has a width adjusted to exceed
that of a button of a supporting element of an articulated latch. The vertical rip
has a width adjusted by default to that of a vertical groove of a vertical plate that
has a cleavage in which a radial arm of said second toothed rotatory lever enters
that is geared with a first toothed rotatory lever provided with a jut that with a
certain delay is inserted into the run of a radial protrusion of the follower in the
rotational direction for opening the lock, at the same time the radial extension of
the follower supplement is attached under a vertical carriage that comprises a vertical
arm located through the supporting element of the articulated latch the vertical arm
of which has a superior protrusion in a position corresponding to the state of rigidity
of the articulated latch. It can be seen that the elements the multi-purpose casing
of the invention is provided with enable the installation of a set of toothed rotatory
levers (first and second) that - in combination with a follower - enable to move the
vertical plate upwards which by means of its wound channel will trigger the withdrawal
of the lever of the lock which constitutes an anti-panic feature operated by the handle
built in the square hole in which also the follower is disposed. This mechanism can
be combined with a device able to withdraw also the latch without further intervention
of the user.
[0010] It is also proposed that the brackets of the supporting element of the latch exist
as collateral half shafts axially aligned to those in which each of the diameter rollers
is disposed so that they protrude in front of the proper brackets and their anterior
vertical tangential plane is at a distance to the back of the head of the articulated
latch in a measure reciprocal to the diameter of the superior protrusion of the vertical
arm.
[0011] Herein, said roller has - according to a distinctive feature of the invention - an
internal diameter that is reciprocal to the external diameter of an internal half-shell
that at its end that is closest to the respective bracket is provided with a discoid
flange. In this respect, it is another distinctive feature of the invention that at
least the half-shells are made of a plastic with a good resistance to friction.
[0012] This proposed simple solution shows a high efficacy in achieving a high smoothness
for the maneuver of inserting/withdrawing the superior protrusion of the vertical
arm in the free space between the head and the supporting element of the articulated
latch; a smoothness which is also traduced into a highly reliable and silent functioning.
[0013] This and other characteristics and use options of the invention are illustrated in
detail by means of graphic representation contained in the enclosed drawing pages.

Description of a preferred embodiment
[0016] Referring to the drawings and reference signs listed above a preferred execution
mode of the object of the invention is described in consequent levels. It concerns
a multi-purpose casing for reversible actuation and traditional and/or anti-panic
actuation in locks for joinery based on metallic sections. Taking as references superior,
inferior, anterior and posterior corresponding to the working position of the lock
built in a door, the casing according to the invention consists (figure 1) of a body
(1) of a casing, a lateral cover (2) and a front (3); the body (1) is limited by a
lateral wall (1a), a superior wall (1b), an inferior wall (1c) and a posterior wall
(1d); the lateral wall (1a) has an opening for the first bearing (1e), second bearing
(1f) and third bearing (1g), respectively, as well as a vertical rip (1h) and a retention
(1i) emerging from its internal face, a vertical window (1j) and a horizontal groove
(1k); paired with those of the body (1) the cover (2) has a first bearing (2a), second
bearing (2b) and third bearing (2c), respectively, and paired with the vertical window
(1j) and the horizontal groove (1 k) of the body (1) this cover has a vertical window
(2d) and a horizontal groove (2e). The pairs of first bearings (1e, 2a), second bearings
(1f, 2b) and third bearings (1g, 2c) have diameters reciprocal to those of the shaft
lugs corresponding to an assembly of follower (4) and follower supplement (4a), and
to a first toothed rotatory lever (10) and a second toothed rotatory lever (11); the
horizontal groove (1 k) of the lateral wall (1 a) is larger than the horizontal groove
(2e) of the cover (2) and has a width adjusted to exceed that of a button (7h) of
a supporting element (7b) of an articulated latch (7); the vertical rip (1 h) has
a width adjusted by default to that of the vertical groove (12c) of a vertical plate
(12) that has a cut-out (12a) in which a radial arm (11a) of said second toothed rotatory
lever (11) enters that is engaged with said first toothed rotatory lever (10) provided
with a jut (10b) that with a certain delay is inserted into the run of a radial protrusion
(4b) of the follower (4) corresponding to the rotational direction for opening the
lock, at the same time the radial extension (4c) of the follower supplement (4a) is
attached under a vertical carriage (17) that engages with a vertical arm (18) reaching
through the supporting element (7b) of the articulated latch (7) the vertical arm
(18) of which has a superior protrusion (18a) with a position corresponding to the
state of rigidity of the articulated latch (7). This description includes an application
of the casing for housing an anti-panic mechanism the functioning of which is clearly
illustrated by means of figures 1 to 3: On turning the follower (4) by means of the
handle the radial protrusion (4b) triggers the protrusion (10b) of the first toothed
rotatory lever (10) that by its engagement with the second toothed rotatory lever
(11) effects this one to be turned and that by its radial arm (11 a) inserted in the
cut-out (12a) of the vertical plate (12) the elevation of the latter is triggered
that by means of its rivet (12f) of the vertical plate (12) will withdraw the lever
(5) of the lock.
[0017] This mechanism of anti-panic withdrawal of the lever (5) of the lock can be combined
with another of automatic withdrawal of an articulated latch (7). Its construction
and functioning are illustrated by figures 4 to 9, while figures 10 to 17 show the
corresponding exploded view. According to the constitutive particularities of the
invention it is required in this respect that the vertical arm (18) has an inferior
protrusion (18b) that is at a distance to the superior protrusion (18a) to a larger
measure than the height of the supporting element (7b) of the articulated latch (7);
that the inferior protrusion (18b) is applied on the vertical carriage (17); that
there is a vertical spring (19) intercalated between the inferior protrusion (18b)
of the vertical arm (18) and the supporting element (7b) of the articulated latch
(7); that the vertical arm (18) has a lowered position corresponding to the relaxed
state of the vertical spring (19) and in which the superior protrusion (18a) remains
inserted in a hollow between the head (7a) and the supporting element (7b) of the
articulated latch (7); and that the vertical arm (18) has an elevated position corresponding
to the compressed state of the vertical spring (19) and in which the superior protrusion
(18a) remains outside the hollow between the head (7a) and the supporting element
(7b) of the articulated latch (7). In order to explain how the anti-panic withdrawal
of the articulated latch (7) is effectuated we start from the position reflected in
figures 4 and 5 in which the head (7a) is turned such that one face is abutted against
the rim of the locking plate (20) (in the rotational direction for opening the door.
See arrow in figure 5), the vertical carriage (17) is resting in the radial extension
(4c) of the follower supplement (4a), the vertical spring (19) is expanded and the
vertical arm (18) is lowered so that its superior protrusion (18a) is situated between
the head (7a) and the supporting element (7b) of the articulated latch (7); on continuing
the turn with the handle (figures 6 and 7) (after withdrawing the lever (5) of the
lock) the radial extension (4c) triggers the lifting of the vertical carriage (17),
thereby compressing the vertical spring (19) and producing the lifting of the vertical
arm (18) unto a position in which its superior protrusion (18a) is not blocking anymore
the free turn of the head (7a) on its vertical shaft (7c) so that on continuing the
opening movement of the door it results that the head (7a) is turned into a position
of figure 7. This is the moment when, as the latter can't be continued to be turned
anymore, the horizontal retraction of the whole set is produced by the proper force
of the thrust of the door until the position of figures 8 and 9 is reached, at which
the door is already open. According to another distinctive feature of the invention
it is realized that: The articulation between the head (7a) and the supporting element
(7b) of the articulated latch (7) is materialized in a shaft (7c) that has an annular
intermediate recess; that transversal to the shaft (7c) a retractable pin (7e) is
inserted into the supporting element (7b) with which a helicoid spring (7g) is associated.
Its retractable pin (7e) has an annular recess (7f) that crosses especially (figure
14) with the annular deepening (7d) of the shaft (7c) and its radius corresponds to
the radius of this shaft (7c). That its retractable pin (7e) has a head that is located
along the horizontal groove (2e) of the cover (2); that the retractable pin (7e) has
a non-triggered position corresponding to that its head is located along the horizontal
groove (2e) and that its annular recess (7f) is deviated from the annular deepening
(7d) of the shaft (7c) (figure 22); that the retractable pin (7e) has a triggered
position corresponding to that its head is outside the horizontal groove (2e) and
more inside than the internal face of the cover (2): and that said triggered position
corresponds to an extended position of the articulated latch (7) in which the button
(7h) of the supporting element (7b) is at the anterior end of the horizontal groove
(1 k) of the lateral wall (1 a) of the body (1), the head of the retractable pin (7e)
is in the broadside of the wall of the front (3) of the body (1), and the shaft (7c)
is ahead of this front (3). This construction is also compatible with the favored
multi-purpose casing in its mounting and functioning by means of figures 20 to 25;
starting from the resting situation shown in figures 20 to 22, on triggering the retractable
pin (7e) in combination with the anti-panic spring latch (22) expulsing it the situation
of figures 23 and 24 can be reached in which the retractable pin (7e) is maintained
compressed by the rim of the opening that for its exit has the front (3) whereby the
annular recess (7f) is not inhibiting anymore that the vertical shaft (7c) is already
staying outside of said front (3) (figure 24); all this by turning the head (7a) upside
down by 180° (figure 25) the reversibility of the articulated latch (7) is achieved
so that it serves for the lock of a door that is opening in the opposite direction
than originally; the extraction of the articulated latch (7) indicated in figures
23 and 24 is enabled thanks to the larger length of the horizontal groove (1 k) (figure
21) in respect to that of the horizontal groove (2e) (figure 23).
[0018] The casing according to the invention is also compatible with a safety device that
is illustrated by figures 26 to 40. According to that it is required: That because
the concave retract (12b) has a vertical profile bridged with an inferior foot in
which a first hollow (12i) and a second hollow (12j) are separated by a division wall
(12h); the first hollow (12i) has a somewhat larger width than the vertical rip (1
h) of the lateral wall (1 a) of the body (1) of the casing and is vertically aligned
with this vertical rip (1h); the second hollow (12) has a somewhat larger width than
the retention (1i) of the lateral wall (1 a) with which it is vertically aligned;
that the concave retract (12b) has a horizontal recess that opens in its posterior
rim and that in its back has a guiding rail (12e) for a horizontal spring (14) interposed
between the back of this horizontal recess (12g) and an anterior front of a horizontal
carriage (13) and some teeth (12k) that bring the horizontal carriage (13) to its
initial position; that there is a horizontal carriage (13) that has a height reciprocal
to the internal height of the concave retract (12b) and a horizontal measure less
than the deepness of the horizontal recess (12g) of the latter; that at the posterior
end of the superior ramification of the horizontal recess (12g) there is a part interfering
with the opening turn of the tappet (8) in a section of it corresponding to the outmost
positions (superior and inferior) of the vertical plate (12); that the horizontal
carriage (13) is in a position corresponding to the expanded state of the horizontal
spring (14); and that the horizontal carriage (13) is in a position corresponding
to the compressed state of the horizontal spring (14) and with an intermediate position
of the turn for opening the tappet interfered by the position of the horizontal carriage
(13) which corresponds to said expanded state of the horizontal spring (14). Figures
26 to 32 show an exploded view and the mounting of the subset built by the vertical
plate (12) and the horizontal carriage (13). In the following paragraph the functioning
is explained.
[0019] For violating a lock of this type a splint is inserted into the hollow between the
front (3) and the lever (5) that acts on the rivet (12f), pushing it upwards and effectuating
the withdrawal of the lever (5) of the lock. For avoiding it, according to the invention,
when the lock is in a resting position (figures 35 and 38) the horizontal carriage
locates its vertical partition (13a) directly under the retention (1i) of the lateral
wall (1 a) of the body (1) of the casing which will block the fraudulent lifting of
the vertical plate (12); when the key is turned in the cylinder of the lock it occurs
(figure 39) that its tappet (8) effectuates the displacement of the horizontal carriage
(13) by compressing the horizontal spring (14) so that the vertical partition (13a)
withdraws from its blocking position and allows the operative lifting of the vertical
plate (12), as is shown in figure 40.
[0020] Another device that is compatible with the inventive casing is illustrated by figures
41 to 49. Its construction requires: That there is a horizontal balancer (15) that
in one site of its body has a horizontal shaft (15a) which crosses the broadside of
the casing (1-2); that the balancer (15) displays - in regard of its shaft (15a) -
anterior and posterior arms that are substantially horizontal; that the balancer (15)
has a non-swiveled position corresponding to that its anterior arm is adjacent with
its end and somewhat lower than an opening (3a) in the front (3) of the casing (1-2);
that the balancer (15) has a non-swiveled position corresponding to that its anterior
arm remains facing laterally the respective vertical windows (1j and 2d) of the lateral
wall (1a) of the body (1) of the casing; that the balancer (15) has a non-swiveled
position corresponding to that its posterior arm has its end right in front of the
vertical posterior crossbar (6a) of a one-piece latch (6); that the balancer (15)
has a swiveled position corresponding to that its posterior arm has its end somewhat
higher of a vertical posterior crossbar (6a) of a one-piece latch (6); that the pairs
of vertical windows (1j, 2d) are somewhat broader than a vertical posterior crossbar
(6a) of a one-piece latch (6) and that they are located corresponding to a position
of forced extension of this one-piece latch (6). This device allows for the reversibility
of the complete latch (6) in a very simple and quick way: Starting from the resting
position of figure 41 in which the vertical posterior crossbar (6a) doesn't allow
that the one-piece latch (6) exits further because it hits against the posterior arm
of the balancer (15); this resting position of the balancer (15) is marked by the
foot (1 m) of the casing (1) when it presses against the face (15c) of the balancer
(15). Thus, the resistance against cycles of this balancer (15) is larger, when the
latch (6) after withdrawing returns to its position by action of the latch spring
(22); it is the face (15c) that upholds the pressure against the face (1 m) of the
casing (1). On introducing the tip of a screwdriver or the like through the opening
(3a) of the front (3) (figure 46) or through the respective vertical windows (1j and
2d) of the body (1) and the cover (2) it is achieved that the balancer (15) passes
to the position indicated in figure 42 by the action of the one-piece latch spring
(21), whereby the one-piece latch (6) can be extracted and turned (figure 43) to the
position opposite to that of the beginning. For recovering the resting position a
respective execution mode consists in that the balancer (15) comprises (figures 45
and 47) an elastic membrane that emerges as a cantilever between the posterior arm
of the balancer (15) and a superior tip (1l) comprised in the lateral wall (1a) of
the body (1) of the casing; another execution mode consists (figure 44) in that there
is a torsion spring (16) mounted between the superior wall (1 b) of the body (1) of
the casing and the superior arm of the balancer (15).
[0021] Furthermore, by means of the curves (6b) located on the vertical posterior crossbar
(6a) the balancer (15) is lifted which allows the one-piece latch to turn. Once a
complete turn is carried out the mere insertion of the latch brings the latch in the
final position (figure 41) by means of the elastic membrane (15b) or, if applicable,
by the torsion spring (16).
[0022] The brackets (7i) of the supporting element (7b) of the latch (4) have some collateral
half-shafts (7k) axially aligned with those that are mounted on the respective rollers
(23) with a diameter that they protrude in front of the proper brackets (7i) and that
their vertical anterior tangential plane is distant from the head of the articulated
latch in a reciprocal measure to the external diameter of the ring (18c) being concentric
with the superior protrusion (18a) of the vertical arm (18). In figures 50 and 51
only the lowered position of the vertical arm (18) is shown, as this is the most enlightening
for this purpose; the elevated positions of figures 3, 4, 6 and 7 can be easily deducted
when bearing in mind that the brackets (7) are now equipped with the roller (23) device.
[0023] The exploded view of figure 52 clearly illustrates the new device as being operatively
mounted in figures 50 and 51. At the same time the distinctive feature of the invention
is highlighted that consists in that the internal rotatory half-shell (24) is in the
middle between a roller (23) and the half-shaft (7k). These rollers (23) have an internal
diameter that is reciprocal to the external diameter of an internal half-shell (24)
that at its end that is closest to the respective bracket (7i) is provided with a
discoid flange (24a).
[0024] According to another distinctive feature of the present invention it is required
that at least the internal half-shells (24) are made of a plastic with a good resistance
to friction.
[0025] The new benefit of this device in regard to its reference patent is that during the
maneuver accomplished by the ring (18c) that is concentric with the protrusion (18a)
of the arm (18) for passing from its lowered position to its elevated position for
unblocking and allowing the turn of the latch (7) in which it exits from the free
space between the brackets (7i) of the supporting element (7b) and the back of the
articulated head (7a) of the latch (7), the rollers (23) will then start rolling on
the surface of the ring (18c) that is concentric with the protrusion (18a) of the
arm (18). This effects that the maneuver runs very smoothly; the same occurs in the
reverse maneuver when the vertical arm (18) passes from its elevated position to its
lowered position. At the same time this new arrangement is in favor of the liability
of the maneuver of facilitating the insertion, even when there is a small deviation
or misalignment in the movement of said superior protrusion (18a) of the vertical
arm (18).
[0026] In this operative mode it is supposed that the maneuvers of insertion/withdrawal
of the ring (18c) that is concentric with the protrusion (18a) of the arm (18) are
produced by turning, in contrast to the frictional gliding as in conventional locks.
