[0001] The object of the invention is an installation pack as presented in the preamble
of claim 1 and an arrangement as presented in claim 4 for installing in an elevator
a flexible member, such as a hoisting member, a traction member or a current & data
cable, of an elevator.
[0002] Nowadays the delivery of the flexible members of an elevator, such as the hoisting
ropes of an elevator, is implemented in separate cardboard boxes, in which is a reel
fabricated from wood and/or metal, onto which the flexible member is prewound. In
the installation phase the reel is taken out of the packing case and fitted onto a
separate installation rack functioning as a tool, from which the flexible member,
such as rope, can be unreeled in order to prevent twisting of the flexible member.
Twisting would produce abrupt loops that would make installation of the flexible member
more difficult. When unreeling a flexible member, such as rope, the rotation of the
reel must be restricted to prevent uncontrolled discharge of the rope from the reel
when the reel rotates momentarily faster than the rope can be fed into the roping
to be formed.
[0003] In the solutions known in the art the flexible members, such as ropes, of elevators
are installed one at a time with a type of discharge device that is designed so that
free rotation of the rope with the reeling device is prevented by the aid of spring
force. In this case greater friction is achieved by tightening the spring and free
discharge of the rope from the reel is prevented. Additionally, it is known for a
helper to brake the reel e.g. manually or by the aid of some auxiliary device.
[0004] There are, however, significant drawbacks attached to prior art. Regulation of the
discharge device described above is difficult and so it often happens that the flexible
member, such as rope, either discharges too quickly or does not discharge at all.
In addition, e.g. the simultaneous discharge of ropes with prior-art devices is difficult.
Thus installation of the roping becomes more difficult and takes a lot of time. Another
problem is the need for the aforementioned installation racks, because there is no
other use for the installation racks. Nevertheless, very many installation racks are
needed in connection with installation, because elevator models are often different
and often many elevators are installed at one time. The storage of the aforementioned
installation racks and their transfer from the store to the worksite and back to the
store is both expensive and ecologically detrimental to the environment.
[0006] The aim of the present invention is to eliminate the aforementioned drawbacks and
to achieve a cheap, ecofriendly, operationally reliable and easily implemented arrangement
for installing in an elevator a flexible member, such as a hoisting member, a traction
member or a current & data cable, of an elevator. A hoisting member and traction member
can be e.g. a belt or a rope. Additionally the purpose of the invention is to achieve
an ecofriendly installation pack of the flexible member, which pack can be delivered
for recycling after use. The installation pack according to the invention is characterized
by what is disclosed in claim 1 and the arrangement according to the invention is
characterized by claim 4 . Preferred embodiments of the invention are subject matter
of the corresponding dependent claims.
[0007] Some inventive embodiments are also discussed in the descriptive section of the present
application. Likewise the different details presented in connection with each embodiment
can also be applied in other embodiments. In addition it can be stated that at least
some of the subordinate claims can in at least some situations be deemed to be inventive
in their own right.
[0008] By means of the invention significant advantages are achieved. Thus, the self-weight
of a reel and a flexible member, such as a rope, ensures a reliable braking force
is achieved. Since the discharge speed of a flexible member, such as a rope, from
the reel in connection with installation can be e.g. approx. 10 m/s, or even more,
it must be possible to stop the reel reliably immediately the discharge of the flexible
member ends. When the reel is lowered onto the base of the packing case, the ratio
of rotation force and weight is generally essentially constant in connection with
braking.
[0009] One advantage of the solution according to the invention is also that the packing
case of the flexible member simultaneously functions as an installation rack when
the flexible member is unreeled to the disposal location. Thus surplus installation
racks, storage locations of them, and also transfers of them between the installation
location and the storage location are not needed at all because the packing case itself
also functions as an installation rack.
[0010] Another advantage is that the aforementioned flexible members are all the time before
installation in the packing case in a space that is well protected from humidity and
dust and that does not need to be opened before installation. Another advantage is
that both the reels and all the structures needed for protecting the reels and for
reeling a flexible member into the disposal location are recyclable and environmentally
benign. A further advantage is also that the reel according to the invention is very
quickly deployed because separate installation racks are not needed.
[0011] In the following the invention will be described in more detail by the aid of some
examples of its embodiment with reference to the attached simplified drawings, wherein

[0012] The idea of the solution according to the invention is that for installation purposes
a flexible member 2, such as a suspension member, a hoisting member, a traction member
or a current & data cable of an elevator, wound onto a reel 6 is delivered to the
installation worksite in an installation pack, which comprises at least a packing
case 1, inside which is the flexible member 2 wound onto a reel 6. The flexible member
2, being a suspension member, hoisting member and traction member, is e.g. a belt
or a rope, which rope is preferably essentially small in diameter, i.e. a so-called
thin rope, e.g. approx. 3-8 mm in diameter, suitably e.g. approx. 4 mm. The packing
case 1 forms a storage-time and transportation-time protection and, in addition, during
the installation supports the reel 6 in its position while allowing it to rotate,
forming an installation-time installation rack, in which case a separate installation
rack is not needed for supporting the reel 6 in its position while allowing it to
rotate. In practice a number of these types of installation packs are placed side-by-side
on a level in the building, such as on a floor level or on the floor of the elevator
hoistway or of the machine room, in the installation phase of the elevator, and the
flexible member 2 on the reel 6 is pulled by unreeling into the elevator system, e.g.
by threading the flexible member 2, such as a suspension rope, from the reel 6 directly
onto the diverting pulleys of the elevator.
[0013] Fig. 1 presents an oblique top and side view of one installation pack according to
the invention, which comprises at least a packing case 1 and inside it a reel 6, onto
which the flexible member 2 to be installed, such as a suspension member, a hoisting
member, a traction member or a current & data cable of an elevator, is wound. The
packing case 1 comprises at least a lid, a base, a front side wall 1a, a rear side
wall and side walls 1b, and at least both the base and the side walls 1b are preferably
reinforced. Both side walls 1b have an aperture 3 pointing obliquely downwards in
two directions, the first end of which aperture points obliquely downwards towards
the front wall 1a of the packing case 1 and the second end of which aperture points
obliquely downwards towards the rear wall of the packing case 1. The reel 6 is configured
to be supported by its shaft 7 in the aperture 3 of the side walls 1b. The apertures
3 function as installation means and as a rotational support for supporting the reel
in a manner that allows rotation inside the packing case 1. Instead of apertures 3,
the rotational supports of the rotating shaft 7 can also be fitted entirely inside
the packing case 1 on the inside surface of both side walls 1b. In this case the aforementioned
inside surfaces can have grooves the shape of the aperture 3, which grooves do not,
however, extend through the side wall 1b to the outside of the side wall 1b. In addition,
the front wall 1a of the packing case 1 has an aperture 5, which comprises an openable
lid part 4, which is opened during the installation of the flexible member 2 so that
the flexible member 2 is able to discharge from the reel 6 to the disposal location.
[0014] The whole installation pack is made from environmentally benign recycling materials,
which can be delivered for recycling after installation of the flexible member 2.
The packing case 1, which is essentially a rectangular prism in shape, is a material
composed of vegetable fiber, preferably of wood fiber, such as cardboard, e.g. corrugated
cardboard, which is folded into the necessary number of layers one on top of another.
Correspondingly, the body of the reel 6 is fabricated from vegetable fibers, preferably
from wood fibers pressed together or from another type of cardboard, or also from
wood. Additionally, the shaft 7 of the reel 6 is also fabricated from vegetable fibers,
preferably e.g. from wood fibers pressed together, or the shaft can also be a shaft
turned from wood.
[0015] Figs. 2 and 3 present a sectioned side view of one installation pack according to
the invention. In the situation according to Fig. 2, the reel 6 is in its first position
inside the packing case 1 detached from the inside base 8 of the packing case. In
this case the reel 6 is supported by its shaft 7, in a manner that allows essentially
free rotation, in the first end of the apertures 3. This position allows the reel
6 to rotate essentially freely. If, however, braking is needed for the rotating of
the reel 6, the reel 6 can be disposed in its second position presented by Fig. 3
such that the shaft 7 of the reel 6 is shifted to the second end of the aperture 3,
which second end is lower than the first end. In this case the outer rim of the reel
6 hits the inside base 8 of the packing case 1, in which case the friction produced
by abrasive contact suitably brakes the rotation of the reel 6.
[0016] Fig. 4 presents one installation pack according to the invention, as viewed from
the front of the packing case 1. From Fig. 4 it is clearly seen how the ends of the
rotating shaft 7 of the reel 6 extend in both directions out from the side walls 1b
of the packing case 1 while resting on the apertures 3 that are in the side walls
1b and that are a resting support and rotational support of the rotating shaft 7.
[0017] Fig. 5 presents in more detail a side wall 1b of a packing case 1 of an installation
pack according to the invention, as viewed from the side. The aperture 3 in the side
wall 1b, said aperture supporting the shaft 7 of the reel 6, has two branches, which
branches both point obliquely downwards. The first end 3a of the aperture 3 points
obliquely downwards towards the front wall 1a of the packing case 1 and the second
end 3b of the aperture 3 points obliquely downwards at essentially the same angle
towards the rear wall of the packing case 1. The first end 3a of the aperture 3 is
shorter than the second end 3b, so that the first end 3a of the aperture 3 is farther
from the inside base 8 of the packing case 1 than the second end 3b of the aperture
3. The distance of the aperture 3 from the inside base 8 is dimensioned in relation
to the diameter of the reel 6 to be such that when the shaft 7 of the reel 6 is at
the first end 3a of the aperture 3, the outer rim of the reel 6 is detached from the
inside base 8 of the packing case 1 and correspondingly when the shaft 7 of the reel
6 is at the second end 3b of the aperture 3, the outer rim of the reel 6 rests at
the same time on the inside base 8 of the packing case 1 for achieving a braking effect
on the rotation of the reel 6.
[0018] In the installation pack and in the arrangement according to the invention one or
more packing cases 1 with reel(s) 6 are disposed in the installation phase of the
flexible members 2 side-by-side on a level of a building, such as on a floor level,
on the floor of the elevator hoistway or on the floor of the machine room, and all
the flexible members 2 to be installed in the same context are fed into the elevator
system at the same time by discharging the flexible member 2 from reels 6 rotating
in their position inside a packing case 1 to be used as a reeling rack e.g. by pulling
the flexible member 2 out of the packing case 1 with the elevator's own machine or
with another suitable machine.
[0019] Before the discharging of the flexible member 2 from the packing case 1 the rotating
shaft 7 of the reel 6 is disposed in the first end 3a of the aperture 3, after which
the reel 6 is rotated in the first end 3a of the aperture 3 by pulling the flexible
member 2 out from the reel 6. The rotation of the reel 6 is braked, if necessary,
by shifting the rotating shaft 7 of the reel 6 to the second end 3b of the aperture
3 and by letting the outer rim 6a of the reel 6 rotate against the inside base 8 of
the packing case 1.
[0020] The reel 6 is rotated inside the packing case 1 while supported on the packing case
1 for essentially the whole time of feeding in the flexible member 2. When the reel
6 is rotating in the first end 3a of the aperture 3, the reel 6 is supported via its
shaft 7 on the aperture 3 and at the same time on the side walls 1b of the packing
case 1, and when the reel 6 is rotating in the second end 3b of the aperture 3, the
reel 6 is mainly supported on the inside base 8 of the packing case 1, but receives
its guidance from the aperture 3. After the feeding in of the flexible members 2 and
when the reels 6 are empty, the packing cases 1 with their reels 6 and shafts 7 are
delivered for recycling.
[0021] It should also be noted that the different solutions presented above can be inventive
features together with one or more other features of the invention.
[0022] It is obvious to the person skilled in the art that the invention is not limited
solely to the examples described above, but that it may be varied within the scope
of the claims presented below. Thus, for example, the shape, structure and operation
of the packing case and reel as well as of the rotating shaft can also be different
to what is presented above.
[0023] It is also obvious to a person skilled in the art that the reel can, if necessary,
be braked otherwise than by letting the outer rim of the reel abrade the inside base
of the packing case. The side walls of a packing case can e.g. at a suitable point
have holes, into which can be placed cardboard or wooden pins, against which the reel
can, by suitable shifting, be made to rotate.
