[0001] This invention relates to a method of manufacturing and arranging in operating positions
operating devices for a lock intended for a door or the like, the method being in
accordance with the preamble of claim 1. Such a methods is for example known from
US 4 353 582 A or EP 792980 A. The invention also relates to an operating device mechanism
and a lock in which the operating device mechanism is installed.
[0002] Locks and the operating devices thereof are conventionally manufactured of metal.
However for certain uses it is also known to manufacture separate lock operating devices
of plastics material. The manufacture and assembly of locks of numerous separate parts
is both laborious and costly. Also the storage and handling of numerous parts is complicated.
[0003] An aim of the present invention is to provide a new method of manufacturing, assembling
and arranging so as to be operable, a lock and its constituent parts, by means of
which the drawbacks mentioned above can be minimised. An aim is specifically to simplify
the manufacture and assembly of lock parts so that the transfer and handling of numerous
separate lock parts is avoided.
[0004] According to one aspect of the present invention there is provided a method as claimed
in the ensuing claim 1 of manufacturing and arranging in operating positions operating
devices for a lock. The transfer and handling of a uniform moulding incorporating
lock operating devices is thereby accomplished. Since detaching of the lock parts
from each other is achieved by means of a pressing movement in one direction, the
assembling step or phase is simplified and, if desired, easily automated.
[0005] The pressing step and the assembly of the lock parts can be more easily accomplished
if the body element and the operating devices are of at least substantially equal
thickness in a direction normal to the basic plane.
[0006] Advantageously the body element is cast to comprise a substantially uniform frame
structure including at least one bolt opening. Thus, after detachment, all the parts
are kept together ready for arrangement in their operating positions.
[0007] Conveniently the operating devices include also at least one spring member. With
advantage, from the viewpoint of detaching and casting of the parts, the operating
devices are cast so as to be located on either side of the body element.
[0008] In a preferred embodiment of the invention, the operating devices include a latch
bolt and a follower, which are arranged in the moulding on the same side of the body
element. The spring member can then, with advantage, be a return spring for the latch
bolt which is arranged in the moulding on a different side of the body element to
that of the latch bolt and the follower.
[0009] The follower is advantageously provided with a spring of its own which is cast to
be part of the body element.
[0010] When necessary a dead bolt and its preferably key operated bolt lever element may
additionally be cast to the moulding. To enable these parts to be easily kept apart
from the parts of the latch bolt mechanism during assembly, a partition wall is cast
to the body element and separates the latch bolt mechanism from the dead bolt mechanism.
The partition wall can be dimensioned to be flexible so that after installation it
guides the bolt lever element.
[0011] In practice the dead bolt and the bolt lever element are advantageously cast so as
to occupy different sides of the body element in different planes with regard to the
body element.
[0012] The moulding can be designed so as to comprise all the essential component parts
of the lock. The casting process can, however, be simplified, if the moulding is installed
in a separate lock having a front plate and a lock housing fixed thereto. In this
case the front plate and lock housing can be made of different material to the plastics
injection moulded operating devices. The pressing step can be accomplished directly
against the lock housing so that the body element and the operating devices remain
inside the lock housing after pressing. When the installation occurs directly in the
lock housing in one direction along a rectilinear path, the assembly can be fully
automated.
[0013] In order to assemble and arrange for the operating devices to be in their operating
positions, the connection members or connection points are so located in the moulding
that when the operating devices are broken from the body element in the pressing stage
they are arranged relative to each other in their correct positions required for their
operation thereof. Further at least one guiding member may be cast to the body element.
In this case the guiding member(s) together with the spring for the follower guide
the follower into a correct position when the follower is turned for the first time
after the pressing step or phase. In addition the follower may have a guiding surface
which, when the follower is turned, guides, together with guiding surfaces of the
body element, simultaneously the spring for the latch bolt into a correct place and
to a prestressed operating position, whereby the spring for the latch bolt presses
the latch bolt towards its operating position.
[0014] The lock housing is with advantage provided with a stub shaft. In this case the moulding
may include a wedge element which during the pressing step, under the influence of
the stub shaft, guides the bolt lever element in the direction of the movement according
to the bolt operation of the dead bolt towards the dead bolt simultaneously pressing
the dead bolt into its operating position, in which it extends beyond the inner edge
of the bolt opening in the lock case. In this way the dead bolt is arranged to be
directly in its operating condition as a consequence of the pressing phase.
[0015] According to another aspect of the present invention, there is provided an operating
device mechanism as claimed in claim 16 intended for a lock to be installed to a door
or the like and which comprises a one piece moulding of plastics material.
[0016] According to a further aspect of the present invention there is provided a lock intended
for a door or the like and as claimed in the ensuing claim 25.
[0017] An embodiment of the invention will now be described, by way of example only, with
particular reference to the accompanying drawings, in which:

[0018] In Figure 1 reference numeral 1 designates a moulding, or piece of casting, for operating
devices of a lock. The moulding is preferably made in one piece by injection moulding
of plastics material. The moulding includes a frame-like body element 2 having bolt
openings 2a and 2b and to which all the essential operating devices of the lock, as
a consequence of the moulding or casting, are either fixed by connection members or
connection points (as described in more detail later on) or which are permanently
integrated as parts of the body element. In the embodiment shown these operating devices
include a latch bolt 3, a spring 4 for the latch bolt, a follower 5 for moving the
latch bolt through means, for instance a handle, to be installed at an operating axis
5', a spring 6 for the follower, a dead bolt 7 and a bolt lever element 8 for moving
the dead bolt 7.
[0019] As can be more clearly seen in Figures 2 to 8, the operating devices are located
on opposite sides of a central plane of the body element 2. In particular the operating
devices and the body element are conveniently positioned in three separate spaced
apart and parallel planes. The moulding is made by injection moulding, preferably
using a two part mould including only one joint surface. The operating devices are
located relative to the body element 2 and to each other so that the moulding 1 can
be installed as one piece in one direction along a rectilinear path into a desired
lock casing (cf. Figure 14). This enables full automation of the assembly process
to be achieved using simple devices. The design and location of the operating devices
relative to each other, as well as the design of the body element 2, are also so selected
that there is sufficient space provided between the movable parts for the walls of
the casting mould and for the movements required by the normal operation thereof after
installation of the moulding and detachment of the movable parts. In addition the
body element 2 is designed so as to comprise guiding surfaces 2c and 2d which guide
the movements of the bolts after installation as is described in more detail later
on.
[0020] Figure 9 shows connection members A and B by means of which the latch bolt 3 is fixed
at its arm part 3a to the body element 2 of the moulding 1. Figure 10 shows connection
members C and D by means of which the follower 5 is fixed to body element 2. Figure
11 shows connection members E and F by means of which the spring 4 for the latch bolt
is fixed to the body element 2. Figure 12 shows connection members G and H by means
of which the dead bolt 7 is fixed to the body element 2, and Figure 13 shows connection
members I and J by means of which the bolt lever element 8 is fixed to the body element
2.
[0021] Figure 14 shows a lock casing 9 having a lock housing 10 and a front plate 11 fixed
thereto and provided with bolt openings. A cover for the lock housing 10 is not shown
in the drawings. The location and the dimensions of the connection members A - J are
selected so that when the moulding 1 is installed, as shown in Figure 14, in one direction
along a rectilinear path into the lock housing 10 and the operating devices are pressed,
the connection members can be simultaneously broken and the operating devices moved
relative to each other so as to occupy a common plane with the body element.
[0022] With reference to Figures 14 and 16, the installation of the latch bolt part of the
lock and arranging the latter to be operable occurs as follows. After the moulding
1 has been pressed into the lock housing 10 so that the connection members A - J are
broken and the operating devices are detached from the body element 2, limiting members
12 of the latch bolt 3 are pressed towards the arm part 3a of the latch bolt guided
by the guiding members 13 in the lock housing. In addition the arm part 3a is guided
by the guiding surfaces 2c of the body element. The spring 6 for the follower is an
integral part of the body element 2 and is designed and positioned so that the follower
5 can be installed in the lock casing 9 in the same position as it is when moulded.
The lock housing 10 includes a guiding opening 10a for the follower 5, into which
the follower 5 enters so that it is turnably journalled in the guiding opening 10a
(cf. Figures 15 and 17). The spring 4 for the latch bolt is located between the follower
5 and a guiding cam 14 in the body element in such a position which allows installation
of the latch bolt 3 in the same position as it occupies when moulded. The situation
corresponds to that shown in Figure 14.
[0023] When the follower 5 is turned for the first time by means of a handle or the like
(not shown) about an operating axis 5', the return spring 4 for the latch bolt turns,
due to a guiding surface 5a on the follower 5 and a guiding cam 14 in the body element,
into its operating position, in which it remains under guidance of another guiding
surface 5b on the follower 5 and the guiding cam 14. Simultaneously, the latch bolt
3 is pushed by the spring 4 of the latch bolt towards its operating position, whereby
the limiting members 12 of the latch bolt arm 3a are released and prevent the latch
bolt 3 from being pressed back into an inner position corresponding to its installation
position. In addition, at the same time a recess 5c in the follower 5 is moved towards
the head of the spring 6 of the follower. The spring 6 enters the recess 5c and is
retained in the recess by its spring force. When a handle or the like is pressed below
a horizontal plane, a guiding member 5d on the follower 5 moves beyond a guiding member
15 located in the body element 2. The situation corresponds to that shown in Figure
16. At the same time the guiding member 15 prevents the follower 5 from moving into
its original position and keeps the handle in its correct position and the spring
6 of the follower prestressed.
[0024] A wedge element 16 is used to install the bolt lever element 8 and the dead bolt
7. For this purpose the wedge element 16 cooperates with a stub shaft 17 arranged
in the lock housing 10. Before the pressing measure associated with the installation,
the wedge element 16 and the stub shaft 17 are positioned relative to each other as
is shown in Figures 14 and 15. After the pressing measure, the wedge element 16 and
stub shaft 17 are positioned as shown in Figures 16 and 17. As is apparent from Figures
14-17, when the wedge element 16 is pressed over the stub shaft 17, the guiding surface
16 on the wedge element causes the wedge element to be moved to the left as viewed
in the Figures. As a consequence, the bolt lever element 8 and the dead bolt 7 are
also moved to the left in the Figures, pressed by the wedge element 16. Thus the dead
bolt 7 is moved towards the bolt opening in the front plate 11 somewhat inside the
opening. In this position, the dead bolt 7 is additionally under guidance of the guiding
surfaces 2d on the body element, cf. Figure 16. Due to this arrangement the dead bolt
7 and the bolt lever element 8 can be moulded so as to be positioned in inner positions
relative to their operating position so that they can be installed in the lock housing
10 as a stationary part of the moulding 1.
[0025] Figure 18 shows the lock casing 9 of Figure 16 in a situation in which the latch
bolt 3 is in its normal protruding position pressed by the spring 4 and the dead bolt
7 is also in its protruding position and dead-locked, effected by the bolt lever element
8. In this arrangement reciprocating movements of the dead bolt 7 are provided through
the bolt lever element 8, turning of which is achieved by means of a key (not shown)
insertable through a key hole 18 arranged in the lock housing 10. Dead-locking of
the dead bolt 7 is achieved by means of two cams in the bolt lever element 8. A partition
wall 19 separates the dead bolt part and the latch bolt part of the body element 2
from each other and is dimensioned so as to be flexible. The flexible nature of the
partition wall 19, together with suitably designed guiding surfaces 8a and 8b on the
bolt lever element 8, keep the bolt lever element 8 in its position depending on the
operating position in each case.
[0026] From the viewpoint of assembly it is naturally more simple for the whole operating
device part to be formed of a single moulding or casting as described above. In principle,
when desired, even the whole lock casing may be moulded in one or several pieces by
injection moulding of plastics material, when only the selection of the materials
corresponds to the requirements set by the operating conditions, for instance requirements
for strength. On the other hand, when necessary, the lock casing may also comprise
only one bolt part, i.e. the latch bolt part or the dead bolt part.
[0027] The lock body element, the operating devices and the connection members may be designed,
when necessary, in many different ways as regards their details. The installation
of the lock parts and arranging the lock to be put in an operable condition should,
however, be achieved with as few measures as possible. In practice, when desired,
a part of the connection members may be arranged to be broken for detaching of the
parts after installation by utilizing separate measures in order to provide for the
lock to be operable. In other words all the connection members need not necessarily
be broken already when the piece of casting is installed to its place in the lock
housing. There is also a matter of choice as to on which side of the body element
the different operating devices are moulded, how many planes are involved with the
moulding and to which extent the pieces are located inside each other and/or relative
to the body element.
[0028] Thus, the invention is not limited to the embodiment shown, but several modifications
