Abstract
The invention deals with a lock made up of a box-like structure (1)
whose frontal face brings a slot (2) for the insertion of an actuating
plaque (3). A set of holes (4) is made on the plaque the function of
which is the different sliding of the pins (18), when the plate is
inserted. The pins (18) are hosted into the hollows of an internal dowel
(12). From the body of the pins (18) teeth (20) jut out. The height from
which they stick out is not the same. But when the plaque (3) inserted
is the right one, it pushes the heads (19) of the pins (18) each one of
the needed quantity to make the teeth (20) align. This way the teeth
(20) can slide into the longitudinal groove (10) and this makes possible
the movement of the dowel (12). Since the dowel (12) is linked with a
bar (14) that juts out from the box (1), through a rectangular opening
(7) on the rear side, this bar (14) slides, dragged by the single
movement of the plaque (3), pins (18) and dowel (12) and it makes the
lock change its state from open to closed and vice versa.
Description
The invention is a lock with sliding pins put into action by a removable
plate. It can be applied to doors, furniture panels and objects with panels that
are opened by a special device.
We know that already exist locks with sliding pins which are being
moved by keys, the introduction of which causes the translation of the sliding
pins, pushed from behind by springs. The pins put themselves in position in
such a way as to allow the rotation of the cylinder into which the key has been
introduced. And so, by means of a tooth, which juts out from the cylinder, it
causes the movement of a latch. Or, in a more sophisticated type of locks, it
puts into action mechanical articulations. These latest make the lock change its
state from open to closed and vice versa.
The known locks have a fairly deep structure, at least as deep as the
length of the key. In some cases they could be not suitable for a particular
application and could give rise to problems. Another disadvantage of the
known kind of locks is that they need springy auxiliary devices to prevent the
latches from sliding when the tooth, jutting out from the cylinder, is in the off
position. In this position is possible the insertion and the extraction of the key.
The aim of the present invention is to remove the inconveniences of the
so far known techniques and to create a new kind of lock, thought and
structured in such a way as to take up the minimum space, with regard to the
thickness. This way, the new kind of lock can be used into devices or organs
quite thin. In addition, the new lock makes possible not to require auxiliary
devices to hold the latch in the reached position, when the actuating plaque is
extracted from the slot and anyhow the hosting device is off.
The lock which allows to achieve the above results is a box-like
structure, whit a slot in the front for the insertion of a metal plaque on which
have been made holes or marks following well defined patterns to allow, when
the plaque is inserted into the slot, different interactions with the heads of the
pins, hosted into an internal dowel.
In the off phase, the different combinations of the teeth emerging from
the pins, which align themselves on an internal groove when the metal plaque
inserted is the right one, will allow the dowel to move back and forth. The
dowel is firmly coupled through a rectangular slit, with a little bar. When the
plaque makes the dowel move to and fro, the bar, linked with the dowel, opens
and closes the lock.
The extraction of the metal plaque lets the pins to return to their normal
position. The teeth of the pins, which slide into transversal grooves, don't
allow the dowel to move, when the plaque is off the lock.. So the bar can't
change position. And all this is achieved without any auxiliary device.
The metal plaque is frontally shaped in such a way that it can be inserted
either when the dowel is in the on position or when it is off. The conformation
of the metal plaque is such that, when it is inserted, it pushes the head of the
pins to the position in which the hosting dowel can translate, moving from
open to closed and vice versa.
That is, the lock change its state, from on to off, because the linear
translation of the metal plaque and not for the rotation of a cylinder, as it
happens in usual keys. Therefore, the invention consists in a combination of a
specific lock with pins and a removable metal plaque, upon which has been
made holes of different size and depth. Changing the size and the depth of the
holes makes possible to produce a wide set of different combinations. This
pattern of holes distinguishes the plaque from all the others of the same kind.
Such plaque plays the role of the key, for the present kind of lock and it works
sliding instead of rotating as it happens in the usual kind of key.
The lock, object of the present invention, is made up of a set of
component, among which there are:
- a box-like structure, with a slot in the front for the insertion of a metal plaque;
- a sliding dowel, internal to the box-like structure;
- pins with teeth, pushed from behind by springs; the teeth jut out at different heights on the body of the pins;
- a box rear plate, upon which is made a rectangular slit;
- a bar, linked with the dowel; the bar sticks out through the mentioned slit and puts into action the latch;
- a set of marks and grooves made on the box rear plate, shaped in such a way as to allow or prevent the movement of the teeth.
The position of the grooves, on the box rear plate (or on another internal
box surface), is such that the actuating metal plaque can be inserted and
extracted either when the dowel is up or when it is down. At these two
positions the bar makes the two state open/closed correspond.
The above described structure can be implemented as thin as we like and
so it can be miniaturized. The number of the pins ad the different position of
their teeth gives the possibility to have a wide set of combinations, each of
which has one and only one corresponding actuating plaque. Other
characteristics will be more evident following the description which refers to a
particular shape, showed in the enclosed table at the end, only for convenience
of explanation. This example doesn't restrict the field of the present patent.
In the table:
- the fig. 1 is the axonometric projection of the lock when the metal plaque is not inserted;
- the fig. 2 is the frontal view of the rear side when the plaque is not inserted;
- the fig. 3 is the frontal view of the rear side when the plaque is inserted;
- the fig. 4 is the perspective view of the rear side when the back slab is removed and the dowel is outside;
- the fig. 5 is the frontal view of the base slab from the point of view of the grooves (inner view);
- the fig. 6 is the lateral view of the base slab;
- the fig. is a drawing, in different scale, of the pins pushed from behind by the springs, of the teeth which jut out from the pins, and of the removable plaque with holes.
It must be made clear, anyhow, that the pictures are given only for
convenience of explanation and don't restrict in any way the invention.
In the drawings the components have been marked with arabic numerals:
The invention substantially consists in a lock made up of many
interacting components. They are:
- a box-like containing structure (1) provide at least whit a slot through which is inserted and extracted the actuating plaque (3). Its length is sufficient to allow the grip, when inserted, and its width is sufficientto host the holes (4), which are normally aligned and anyway they are in a corresponding position with the actuating pins (18);
- a internal dowel (12) with some hollows (15) each of which hosts a pushing spring (16) ad a pin (18). On each pin juts out a tooth, the position of which isn't fixed at a specified height. In addition, the dowel is linked with the bar (14) which sticks out from the box-like structure and moves to and fro as the dowel;
- a slab with at least one longitudinal groove (11); it allows the teeth (20) to slide horizontally, when aligned. The transversal grooves (10) allow the teeth to slide vertically. This movement of the pins happens because the pushing action of the springs (16);
- a rectangular opening (7) on the slab of the base (5). Through it juts out the bar (14), linked with the dowel (12). Its movement can actuate one or more latches connected with the lock;
- a metal actuating plaque (3) capable to penetrate inside the box-like structure (1) through the slot(2).
Each hole is made in such a way as to allow the pin to reach the proper
height. This way each pin can slide the right length and, at last, all the teeth are
aligned.
The favorite version of this project is made up of a box-like structure (1)
with a frontal slot (2) through which can be inserted a metal plaque (3). The
rear side bears a opening (7), through which juts out the bar (6) joined to the
internal dowel (12). The latest, by means of two guides (13) (21), can slide
inside the box (1). The two guides (13) and (21) are hosted into the grooves
(9), made on the slab (5) with which the box structure (1) is closed.
From the frontal face the bars (13) work also as guides for the metal
plaque (3), when it is being inserted in the frontal slot (2). They allow the
holes (4) on the plaque to align correctly with the pins (18), with which they
interact. The mentioned pins can axially slide but are constrained to follow the
dowel (12) for the other movements. For this purpose the dowel is provided
with many hollows each of which hosts either the sliding pin (18) and the
pushing spring (16). These last are at least parallel among them and also
normally aligned. In addition each pin has the head rounded to facilitate, in the
insertion phase or in the extracting one, the interaction with the extractable
actuating plaque (3). To define in an univocal way the closed or open state, the
lock comprises within it also a surface or a plate with the face turned inside.
This surface is provided with longitudinal (11) and transversal (10) grooves.
They have the aim to guide the movement of the internal dowel (12) and to
control, through the interaction of the mentioned grooves with the teeth (20),
jutting out from the sliding pins (18), its movements, and so to define the open
and the closed states, as well as the modalities for the passage from one state
to the other.
The mentioned surface with grooves is obtained in the internal part of
the plate (5) which constitutes the closing element of the rear side of the box-like
structure (1). Along its borders it bears also two holes (22) at least and/or
equivalent means for its fixing with screws (8) to the above box structure (1).
Lastly it bears, in the exemplified solution, the jutting bar (6) fit for the
position of the lock in the seat assigned to contain it. This bar (6) is near the
slot (7) through which the other bar (14) emerges, linked with the sliding
dowel, by means of which the levers and/or articulations are moved. By h of
them the lock transmits the translation of the movable dowel to the bolts of
which the door, or other structure on which the lock has been applied, is
equipped.
The movements of the dowel (12) are therefore driven by the removable
plaque (3) when inserted in the lock. The actuation of which can happen only
by a qualified plaque. That is, once the plaque is inserted between the fore
parts that appear in sight of the actuating bars (13) and pushed to the bottom as
far as it reaches the rabbet on the slab (5), or other landmarks, the plaque (3) is
being pushed along the slot (2) moving in this way the sliding dowel (12) and
the bar (14) with it.
The mentioned operating plaque bears, on the introducing side, a set of
holes (4) or a corresponding set of marks, dimensioned and/or placed in such a
way as to determine, when inserted, related axial sliding of the pins (18), with
whose free extremities the mentioned holes or marks interact.
This causes the sliding of the same pins (18) in such a way as to align all
the teeth (20) of the pins. When the teeth are aligned with the longitudinal
groove (11) (or with the longitudinal mark made on the internal surface of the
slab (5)), the dowel, which bears the pins, can slide horizontally with them,
until it reaches the other allowed position, at which corresponds other grooves
(10) for the teeth. So, if the metal plaque (3) is then extracted, the pins, pushed
by the springs (16), go back at their original sides, locking the dowel (12) and
the bar (14) in the reached position. This way the bar is prevented from sliding,
the lock condition is satisfied, and all this is achieved without any other
auxiliary device, instead of what happens in the known kind of locks.
The actuating plaque is rounded in the inserting side so to ease the
interaction with the heads (19) of the pins. This characteristic, when the plaque
is being inserted or removed, makes the pins slide along their side.
