The present invention relates to an elevator and to a
method for locking an elevator car in place.
According to prior art, an elevator car can be locked
in place by means of a separate locking device. In a
prior-art solution, the elevator car is locked in
place by means of a bolt, the elevator car being
provided with an apparatus for pushing the bolt into a
hole in a guide rail so as to lock the elevator car in
place. Another prior-art solution is disclosed in spe-
cification US 4,333,549, which describes a blocking
apparatus for blocking an elevator car in place. The
specification discloses a separate blocking apparatus
by means of which the elevator car is blocked manually
in place by using a separate blocking device. In this
solution, the elevator car must always be blocked
manually separately at each desired position and the
aforesaid blocking device must always be locked and
released manually by means of a tightening bolt. In
these solutions, the problem is a slow and complicated
arrangement for blocking the elevator car in place.
Another problem is that the solutions proposed are not
very well applicable for use e.g. in elevator solu-
tions without counterweight.
The object of the present invention is to overcome the
above-mentioned drawbacks and to achieve an easy and
simple locking apparatus for locking an elevator car
in place. The invention aims at achieving at least one
of the following objectives. On the one hand, the in-
vention aims at developing an elevator car without ma-
chine room so as to allow more effective space utiliz-
ation in the building and in the elevator shaft than
before. This means that the elevator must be capable

of being installed in a fairly narrow elevator shaft
if necessary. On the other hand, the invention aims at
permitting the use of the elevator's own safety equip-
ment even during elevator installation and maintenance
work without a need to add any separate additional
safety devices or separate locking devices to the el-
evator car. A further aim is to increase and ensure
the safety of an elevator.
The elevator, method and other embodiments of the in-
vention are described hereinafter. Inventive embodi-
ments are also presented in the description part of
this application. The inventive content of the present
application can also be defined in other ways. The in-
ventive content may also consist of several separate
inventions, especially if the invention is considered
in the light of expressions or implicit sub-tasks or
in view of advantages or sets of advantages achieved.
In this case, some of the attributes contained in the
claims below may be superfluous in respect of separate
inventive concepts.
By applying the invention, one or more of the follow-
ing advantages, among others, can be achieved:
- the locking device locking the elevator in place by
means of at least one safety gear can be easily used
both during installation work and later during main-
tenance work
— the locking of the elevator car in place is easy and
cheap to implement

- the locking mechanism is simple as the locking of
the elevator car in place is implemented using a
safety gear provided in conjunction with the eleva-
tor car, so there is no need for any separate addi-
tional locking devices
- the invention enables the locking mechanism to be
used all the time during the operation of the eleva-
tor without having to make any separate installa-
tions e.g. for the time of maintenance and/or in-
stallation work
- the locking mechanism of the invention can also be
implemented in a manner permitting the inclusion of
a separate locking element for use during mainte-
nance and/or installation work, which element pref-
erably comprises a pedal for the transmission of a
force to release the safety gear/safety gears and
which can be taken along after maintenance work
- the locking element, preferably a pedal, included in
the locking mechanism is easy to carry along and it
is light in construction
- the locking mechanism provided with a separate lock-
ing element can not be used incorrectly because, as
pressing the pedal does not actuate the safety gear
locking linkage to keep the safety gear released,
the safety gear stops the elevator automatically
- the separate locking element can be quickly and
easily installed in position in the elevator for
the time of maintenance and/or installation work or
in other situations where installation/maintenance
personnel have to get onto the top of the elevator
car.
In the elevator of the invention, which preferably is
an elevator without counterweight, wherein the eleva-

tor car is suspended by hoisting ropes consisting of a
single rope or a plurality of parallel ropes, and
which elevator comprises a traction sheave which moves
the elevator car by means of the hoisting ropes. The
elevator has rope portions of the hoisting ropes going
upwards and downwards from the elevator car. In addi-
tion, the elevator has at least one safety gear fitted
in conjunction with the elevator car and engaging a
guide rail. The elevator car of the invention is
provided with a rope elongation compensating device
for maintaining the rope force ratio between rope por-
tions going upwards and downwards from the car con-

stant, and in that the elevator comprises an overspeed
governor by means of which the safety gear is activ-
ated during normal elevator operation in a situation

where a predetermined speed of the overspeed governor
is exceeded, and in that the elevator is provided with
a locking device fitted in conjunction with the elev-
ator car for locking the elevator car in place, said
device comprising means for activating and releasing
the at least one safety gear fitted on the elevator
car.
The method of the invention relates to locking the el-
evator car in place in an elevator. The elevator car
is at least partially suspended by hoisting ropes,
said hoisting ropes consisting of a single rope or a
plurality of parallel ropes. The elevator has a trac-
tion sheave which moves the elevator car by means of
the hoisting ropes, and the hoisting ropes of the el-
evator comprise rope portions going upwards and down-
wards from the elevator car. In addition, the elevator
is provided with at least one safety gear fitted in
conjunction with the elevator car and engaging a guide
rail. In the method of the invention, at least one
safety gear fitted in conjunction with the elevator

car is activated and released by means of a locking
device fitted in conjunction with the elevator car.
By increasing the contact angle by means of a rope
pulley functioning as a diverting pulley, the grip
between the traction sheave and the hoisting ropes can
be improved. This allows the car to be made lighter as
well as smaller, thus increasing the space saving po-
tential of the elevator. A contact angle of over 180°
between the traction sheave and the hoisting rope is

achieved by utilizing a diverting pulley or diverting
pulleys. The need to compensate the rope elongation is
due to the friction requirements to ensure a grip be-
tween the hoisting rope and the traction sheave that
is sufficient in respect of operation and safety of
the elevator. On the other hand, it is essential to
elevator operation and safety that the rope portion
below the elevator car in an elevator solution without
counterweight be kept sufficiently tight. This can not
necessarily be achieved by using a spring or a simple
lever.
In the following, the invention will be described in
detail with reference to a few embodiment examples and
the attached drawings, wherein
Fig. 1 presents a diagram representing a traction
sheave elevator without counterweight and a
locking mechanism according to the invention,
and
Fig. 2 presents a diagrammatic illustration of an
elevator according to the invention and its
locking mechanism, which locking mechanism
has been fitted to the car frame of the ele-
vator.
Fig. 1 presents an elevator without counterweight ac-
cording to the invention, in which elevator a roping
arrangement with a 2:1 suspension ratio is used in the
portions of the hoisting ropes 3 above and below the
elevator car 1 and DW roping is used between the trac-
tion sheave 5 and the diverting pulley 7. Compensation
of rope elongations and constant rope forces are im-
plemented using a rope elongation compensating device
as presented in Fig. 1, which produces a rope force
ratio of T1/T2 = 2/1. In the elevator it is also pos-
sible to use a different type of hoisting rope compen-
sator, such as e.g. a lever or a tensioning wheel set

or some other compensating device applicable for the
purpose. In Fig. 1, the hoisting ropes run as follows.
One end of the hoisting ropes is secured to a divert-
ing pulley 25 fitted to hang on the rope portion com-
ing downwards from diverting pulley 14. Diverting pul-
leys 14 and 25 together with the anchorage 26 of the
second end of the hoisting rope form a rope force com-
pensating system, which in the case of Fig. 1 is a
compensating sheave system. This compensating device
is fitted in place in the elevator shaft. From divert-
ing pulley 25, the hoisting ropes 3 go upwards and
meet diverting pulley 14, which is mounted above the
elevator car in the elevator shaft, preferably in the
upper part of the elevator shaft, passing around it
along rope grooves provided in the diverting pulley
14. These rope grooves may be coated or uncoated, the
coating consisting of e.g. a friction increasing mate-
rial, such as polyurethane or some other appropriate
material. From diverting pulley 14, the ropes go fur-
ther downwards to a diverting pulley 9 fitted in place
on the elevator car, and having passed around this
pulley, the ropes 3 go further upwards in tangential
contact with diverting pulley 6 to the traction sheave
5. Diverting pulley is preferably fitted in the vicin-
ity and/or in conjunction with the hoisting machine 4 .
Between diverting pulley 6 and the traction sheave 5
of the hoisting machine 4, the figure shows DW (Double
Wrap) roping, in which roping the hoisting ropes 3 run
in tangential contact with diverting pulley 6 upwards
to the traction sheave 5, and having passed around the
traction sheave 5 the hoisting ropes return to divert-
ing pulley 6, pass around it and return back to the
traction sheave 5. In Double Wrap roping, when divert-
ing pulley 6 is substantially of the same size with
the traction sheave 5, the diverting pulley 6 can also
function as a damping wheel. In this case, the ropes
going from the traction sheave 5 to the elevator car 1

run via the rope grooves of diverting pulley 6, and
the rope deflection caused by the diverting pulley is
very small. It could be said that the ropes going from
the traction sheave 5 to the elevator car only run in
"tangential contact" with the diverting pulley 6. Such
"tangential contact" serves as a solution damping the
vibrations of the outgoing ropes and it can be applied
in other roping solutions as well. An example of other-
roping solutions is Single Wrap (SW) roping where the
diverting pulley is substantially of the same size
with the traction sheave of the hoisting machine and.
the use of a diverting pulley is applied as a "tangen-
tial contact wheel" as described above. In SW roping
according to the example, the ropes are passed around
the traction sheave only once, the contact angle be-
tween the rope and the traction sheave being about
180°, the diverting pulley is utilized only for "tan-
gential contact" of the rope as described above, the
diverting pulley functioning as a rope guide and as a.
damping wheel for damping rope vibrations. Diverting
pulleys 14,9,6 together with the hoisting machine 4
form the suspension arrangement above the elevator:
car, where the suspension ratio is the same as in the
suspension arrangement below the elevator car, this
suspension ratio being 2:1 in Fig. 1. From the trac-
tion sheave 5, the ropes run further in tangential
contact with diverting pulley 6 to diverting pulley 8,
which is preferably fitted in place in the lower part
of the elevator shaft. Having passed around diverting
pulley 8, the ropes 3 go further upwards to a divert-
ing pulley 18 fitted in place on the elevator car,
pass around this pulley and then go further downwards
to a diverting pulley 23 in the lower part of the ele-
vator shaft, and having passed around it the ropes go
further upwards and return the diverting pulley 25
comprised in the compensating device. Having passed
around this pulley, the hoisting ropes go further up-

wards to the anchorage 26 of their second end disposed
in a suitable place in the elevator shaft. Diverting
pulleys 8,18,23 form the hoisting rope suspension ar-
rangement and the rope portion below the elevator car.
The elevator hoisting machine 4 and the traction
sheave 5 and/or the diverting pulleys 6,14 disposed in
the upper part of the elevator shaft may be mounted in
place on the frame structure formed by the guide rails
2 or on a beam structure at the upper end of the ele-
vator shaft or they may be secured separately in the
elevator shaft or in some other appropriate mounting
arrangement. The diverting pulleys in the lower part
of the elevator shaft may be mounted in place on the
frame structure formed by the guide rails 2 or on a
beam structure located in the lower part of the eleva-
tor shaft or on some other appropriate mounting ar-
rangement. The diverting pulleys on the elevator car
may be mounted in place on the frame structure of the
elevator car 1 or on a beam structure or beam struc-
tures comprised in the elevator car or they may be
mounted separately on the elevator car or some other
appropriate mounting arrangement. In Fig. 1, the ele-
vator is provided with at least one, preferably two or
more safety gears 27 fitted in conjunction with the
elevator car, which safety gears can be activated and
released by means of a locking mechanism 28. By oper-
ating the actuating element 30 of the locking mecha-
nism 28, the safety gear 27 can be released, allowing
the elevator to be moved and operated e.g. in mainte-
nance mode. In this case, however, the locking mecha-
nism 28 of the elevator is in its service position, in
which position the safety gear 27 is in an activated
state when the actuating element 30 is not acted on.
When the locking mechanism of the elevator is in a
normal position, the elevator safety gear 27 is in a
released state and the elevator works in the normal
way.

Fig. 2 presents a locking mechanism according to the
invention arranged in conjunction with the car frame
of an elevator car, by means of which mechanism the
elevator car can be locked in place e.g. during in-
stallation and/or maintenance work. In the figure, the
safety gear 227 is fitted to the car frame so that it
will engage the elevator guide rails so as to lock the
elevator car in place on the elevator guide rails. The
elevator car may have more than one safety gear, pref-
erably two or more safety gears fitted on it, each one
of which can be actuated by means of the locking
mechanism of the invention. The mechanism presented in
Fig. 2 is in the position of normal elevator opera-
tion, in which position the safety gear is activated
by means of an overspeed governor 231, normally in a
situation where a predetermined speed of the overspeed
governor 231 is exceeded. The overspeed governor acti-
vates the safety gear by means of a linkage 228 ac-
cording to prior art. In the operating position off the
locking mechanism, the linkage 228 activates the
safety gear 227 immediately when the locking mechanism
is turned to the operating position. To do this, using
an actuating element 230, of which there may be more
than one and they may be located anywhere on the ele-
vator car, yet preferably on the top of the elevator
car or in some other location easily accessible to a
person working on the top of the elevator car, the
safety gear 227 is acted on via the linkage 228 so as
to release the safety gear. It is then possible to
drive and/or move the elevator car. The elevator lock-
ing mechanism may be provided with a switching element
for indicating the state of the locking mechanism. For
example, the switching element or elements may indi-
cate when the locking mechanism is in the operating
position, thus informing the elevator system about the
state of the mechanism, and in this situation e.g.
only operation in maintenance mode is possible. The

locking mechanism may also comprise a so-called "dead
man's switch", which is used for monitoring to ensure
that when the actuating element 230 of the locking
mechanism is released, the safety gear is activated,
i.e. grips the guide rail immediately. This arrange-
ment can be easily implemented by using e.g. a gas
spring or some other arrangement applicable for the
purpose, in which arrangement the safety gear is
caused to be activated immediately after the user ac-
tion on the actuating element of the locking mechanism
ceases while the elevator locking mechanism is in the
operating position. An elevator without counterweight
may start moving in an uncontrolled manner only down-
wards during e.g. installation, maintenance or normal
operation because it has no counterweight. In the ele-
vator of the invention, it is possible to use as
safety devices during installation and maintenance
work only the safety gears which can be activated and
released by means of the locking mechanism. In addi-
tion, the safety gears used may be of a type function-
ing in one direction only, in other words, in the case
of an elevator without counterweight, preventing es-
cape in the downward direction only.
Fig. 3 presents a locking mechanism according to the
invention which can be included as a part of the ele-
vator if necessary. For example, a serviceman can add
the locking mechanism to an elevator when he has to
work on the top of the elevator car. Fig. 3 presents a
detachable locking element 332 that can be taken
along. In the arrangement illustrated in Fig. 3, the
locking element is preferably a pedal which is fitted
in place on the elevator car or the frame of the ele-
vator car, on brackets 333 provided for it, and added
as a part of the safety gear locking linkage 330. When
the pedal is pressed down e.g. by foot, the elevator
safety gears will be released in the manner described

in connection with Fig. 1 and 2, whereupon it is pos-
sible to move the elevator car e.g. when the elevator
is to be operated in maintenance mode. The pedal also
functions as a so-called dead man's switch, which
means that when the resistance to the pedal disap-
pears, the safety gears will be activated, i.e. they
will grip, preferably the guide rails of the elevator
car. The locking element 332 together with its actua-
tor can be advantageously placed on either side of the
elevator car and the locking linkage 330, in which
case the elevator car or the car frame of the elevator
car may be provided with at least two mounting points
and/or mounting brackets or other equipment on which
and by means of which the locking element is secured
in place. A serviceman can easily carry the locking
element 332 along due to its light construction. In
addition, the locking element can be easily and
quickly mounted in place as a part of an elevator, and
the locking element is cheap. In respect of operation,
the locking element 332 is simple to mount in place,
and its practically impossible to use it incorrectly
because, when the locking device is not pressing the
locking linkage 330 downwards, the equipment provided
in the safety gear, preferably a gas spring or equiva-
lent, activates the safety gear into the gripping po-
sition and the elevator is stopped.
A preferred embodiment of the elevator of the inven-
tion is an elevator without machine room with machine
above and with a drive machine provided, with a coated
traction sheave, said elevator having thin and hard
hoisting ropes of substantially round cross-section.
In the elevator, the hoisting ropes have a contact an-
gle exceeding 180° on the traction sheave and are im-
plemented as DW roping in the hoisting machine, which
hoisting machine comprises a traction sheave and a di-
verting pulley, and which machine comes with the trac-

tion sheave and diverting pulley ready fitted at a
correct angle relative to each other. The hoisting ma-
chine is secured to the elevator guide rails. The ele-
vator is implemented without counterweight with a sus-
pension ratio of 8:1 in such manner that both the sus-
pension ratio in the roping above the elevator car and
the suspension ratio in the roping below the elevator
car is 8:1, and that the elevator roping runs in the
space between one of the walls of the elevator car and
a wall of the elevator shaft. The elevator is provided
with a compensating device which maintains the ratio
between the forces T1 / T2 as a constant ratio of 2:1.
With the compensating device used, the required com-
pensating distance is half the magnitude of the rope
elongation. The elevator has a locking mechanism for
locking the elevator car in place on the guide rails.
A second preferred embodiment of the elevator of the
invention is an elevator without counterweight wherein
the suspension ratio above and below the elevator car
is 10:1. In this embodiment, conventional elevator
ropes, preferably of a diameter of 8 mm, and a trac-
tion sheave made of cast iron at least in the rope
groove area are used. The traction sheave has undercut
rope grooves and the contact on the traction sheave
has been fitted by means of a diverting pulley to be
180° or more. When conventional 8-mm ropes are used,
the traction sheave diameter is preferably 340 mm. The
diverting pulleys used are large rope wheels which,
when a conventional 8-mm hoisting rope is used, have a
diameter of 320, 330, 340 mm or even more.
It is obvious to the person skilled in the art that
different embodiments of the invention are not limited
to the examples described above, but that they may be
varied within the scope of the claims presented below.
For instance, the number of times the hoisting ropes
are passed between the upper part of the elevator

shaft and the elevator car and. between the elevator
car and the diverting pulleys below it is not a very
decisive question as regards the basic advantages of
the invention, although it is possible to achieve some
additional advantages by using multiple rope passages.
In general, applications are so implemented that the
ropes go to the elevator car from above as many times
as from below, so that the suspension ratios in the
suspension arrangements above and below the elevator
car are the same. It is obvious to the skilled person
that the linkage and/or actuating equipment of the
locking mechanism can be implemented in other ways
than those presented in the examples, e.g. by using
various wire rope arrangements.
It is obvious to the skilled person that the elevator
of the invention can be implemented using almost any
type of flexible hoisting means as hoisting ropes,
e.g. flexible rope of one or more strands, flat belt,
cogged belt, trapezoidal belt or some other type of
belt applicable to the purpose. It is further obvious
to the skilled person that the hoisting machine used
in the elevator may be any type of elevator hoisting
machine applicable for the purpose.
It is also obvious to the skilled person that, in the
elevator of the invention, the elevator can also be
provided with a counterweight, in which elevator for
example the counterweight preferably has a weight be-
low the weight of the car and is suspended by separate
ropes.
