[0001] The invention relates to a mortise lock for mounting in a door or the like, as this
is known by
US-A-5 317 890.
[0002] In case of this known lock an actuation arm of a lock cylinder contacts the bolt
in order to push it outwards, and a conveying element is used for pushing the bolt
of the lock further outwards when this can no longer be done by an actuating arm.
A bore is provided in the bolt, extending square to its direction of movement. A spring-biased
pin is mounted in said bore. Said pin is provided with a second pin being transverse
to the plane of the bolt, said second pin being guided by a slot made in a wall of
the case. The bolt will be weakened by said slot and the other parts can only be of
limited dimensions.
[0003] Now the object of the invention is to overcome this drawback by the provision of
an alternative conveying element arrangement and so the invention provides a mortise
lock for mounting in a door or the like, comprising a case in which a bolt is slidably
received, an actuating arm being connected to an inner cylinder, mounted in an outer
cylinder which is fixedly connected to said case, said actuating arm being rotatable
with the help of a key, a part of said bolt, connected to the part thereof which can
be located entirely outside of said lock, being fittingly received in said case and
is provided with a recess having two side walls extending square to the longitudinal
direction of the bolt, a conveying element being present for cooperating with said
actuating arm, said conveying element, having almost the same thickness as said bolt,
is slidably received in said recess in said bolt and is slidable together with said
bolt and also transversely to its direction of movement and is pushed into the direction
of the actuating arm by means of a spring, said conveying element being provided with
a cavity in which the actuating arm can be received when the key is rotated for moving
said bolt, at least one pin being present in said conveying element either in the
wall of said case, said pin being guided by a bent slot provided in the case either
in said conveying element, the construction being such that after the actuating arm
has moved the bolt outwardly by turning the key said actuating arm will be completely
released from the conveying element by turning the key further, whereby the spring
(11) then presses the conveying element (10) in the direction of the outer cylinder
(17), such that by cooperation of said pin (13) and said bent slot (14) the conveying
element (10) and the bolt (2) are moved further.
[0004] According to an embodiment said conveying element is provided with two pins being
movable in two bent slots in said case for guiding said conveying element in relation
to said case.
[0005] According to an embodiment, both lateral surfaces of the conveying element can be
provided with one pin, said pins being offset in relation to one another, and each
of the lateral walls of the case engaging them can be provided with a slot.
[0006] Due to this, the distance between the pins can remain small in that the slots are
not situated in one single wall and might overlap. Providing slots in the conveying
element would create the risk that said element might get weakened.
[0007] It can be provided for, that each slot has an oppositely bent portion into which
a pin connected to the conveying element can be received when the bolt is pushed back
into the case without using the key.
[0008] Thus, when the key is not used, the bolt can not be pushed into the case, since then
the conveying element will provide a blocking of the bolt.
[0009] The invention is further explained by way of an embodiment, illustrated in the drawing,
in which:
Fig. 1 shows a perspective view of a mortise lock according to the invention, with
the outer and inner cylinders omitted and the bolt slid completely outwards;
Fig. 2 shows a perspective view of the lock of Fig. 1, on a reduced scale, in which
a lateral wall of the case has been omitted and the bolt is received in the house
completely;
Fig. 3 shows diagrammatically a lateral view of the lock when the key is turned thus
far that the actuating arm starts cooperating with the conveying element;
Figs. 4, 5 and 6 show lateral views according to Fig. 3, yet in successive positions
of the parts when the key is turned ever further.
[0010] The drawing shows a mortise lock comprising a case 1 in which a bolt 2 is slidably
received. The case 1 is defined by the lateral walls 3, in which one of said walls
can be connected to the transverse walls 4, so that a housing 5 is formed, to which
the other lateral wall 3 can be fixed by means of screws. At its front side, the housing
5 is provided with a cross-plate 6, with which the lock can be fastened to a door
or the like by means of screws.
[0011] The bolt 2 comprises a part 7 which is fittingly and slidingly received in the case
1, and a part 8 which can project outwards through the cross-plate 6. A recess 9 in
the part 7 of the bolt 2 holds a conveying element 10, which is slidable in the plane
of the bolt 2 and transverse to its direction of movement V, see fig. 3. The conveying
element 10 is spring-loaded by means of a compression spring 11.
[0012] A pin 13 is mounted on each lateral wall 12 of the conveying element 10 and each
pin 13 is received in a slot 14 in one of the lateral walls 3 of the case 1. As indicated
in Figure 3, the pins 13 are offset in relation to each other and obviously this also
applies to the slots 14 in which they are located. As appears from Fig. 1 in particular,
a slot 14 is provided with an oppositely bent part 15, in which the accompanying pin
13 will fall when an inwardly directed force is exerted on part 8 of the bolt 2 in
particular. With normal operation of the lock, as will be described further, the inward
movement of the bolt 2 is limited by the slots 14, possibly in combination with the
transverse wall 4 the of case 1, indicated in Figure 3. Holes 16 are present for fastening
a possibly applicable metal work on the door.
[0013] An outer cylinder 17 is fixedly mounted in the case 1 and the inner cylinder 18 is
rotatable within said outer cylinder 17. Rotation of the inner cylinder 18 takes place
in a known way with the help of a key 19 providing for deblocking of the inner cylinder
18.
[0014] Like with the known cylinder locks, the key 19 can only be inserted in the inner
cylinder 18 when the latter is in the position shown in Figure 2. On rotation of the
inner cylinder 18 in the direction of the arrow P, the actuating arm 20 connected
to it will at a given moment be received in a cavity 21 of the conveying element 10,
as illustrated in Figure 3. The actuating arm 20 now starts acting on the conveying
element 10, causing it to be pushed to the left, as seen in Figure 3. Further, the
conveying element 10 wil move upward, also due to the pins 13 received in the slots
14. With that, the spring 11 will be compressed.
[0015] After the position of the actuating arm 20 shown in Figure 4, the position as shown
in Figure 5 is achieved. Now, the actuating arm 20 comes to lie below a point of the
conveying element 10 and will not be able to push this element further to the left.
[0016] When turning the key 19 further, the actuating arm 20 will be completely released
from the conveying element 1C as shown in Figure 6. The spring 11 then presses the
conveying element 10 downward in the direction of the outer cylinder 17. By the cooperation
of the pins 13 connected to the conveying element 10 and the slots 14 mounted in the
lateral walls 3 of the case 1, the conveying element 10 will move further to the left,
as seen in Figure 6. This will also cause the bolt 2 to move further to the left and
achieve the position illustrated in Figure 6, in which it protrudes beyond the case
1 across the maximum distance, beyond its plate 6 in particular.
[0017] The key 19 can be turned further, so that it will have been rotated across 360 degrees
in total, and can then be taken out of the lock. As appears from Figure 6, after inserting
the key 19 into the lock, the actuating arm 20 can be rotated in the direction of
the arrow R so that the arm will again be received in the cavity 21 of the conveying
element 10. Conveying element 10 can then be moved upwards and to the right in order
to pull the bolt 2 back into the case 1.
[0018] As stated earlier, application of two pins 13 and two slots 14 will be preferred
in order to guide the conveying element 10 in the recess 9 in the bolt 2 in the best
possible way. It is possible to apply one single pin 13 and a slot 14, but this will
require a more accurate guiding of the conveying element 10 within the recess 9.
[0019] Further, it is possible to make the slots 14 in separate plates which can be secured
on the lateral walls 3 of the case. Then, the lateral walls can be closed, so that
the penetration of dirt into the case is prevented.
[0020] Like with known locks, the lock can be designed in such a way, that the actuating
arm can be rotated from both sides of the lock.
[0021] It will be obvious, that only one possible emodiment of a mortise lock according
to the invention has been illustrated in the drawings and described above, and that
many changes can be made without leaving the inventive idea, as it is indicated in
the appended claims.
