METHOD AND ARRANGEMENT FOR FITTING A BENDING BODY IN A LIFT AND BINDING BODY INSTALLATION KIT

The invention relates to a method as set forth in the preamble of claim 1 and to an arrangement for installing a flexible member such as a lifting member, a traction member or a power and data cable in a lift as set forth in the preamble of claim 9.

Nowadays, the delivery of the flexible elements of the elevator, such as the lifting ropes of the elevator, has been carried out in separate cardboard boxes with a reel made of wood and / or metal on which the flexible member is pre-wound. During the installation step, the coil is taken out of the packing box and mounted on a separate tool mounting bracket, from which a flexible member such as a rope can be unwound to prevent the flexible member from rotating. Twisting would cause sharp loops that make it difficult to install a flexible member. When winding a flexible member such as a rope, rotation of the reel must be limited to prevent uncontrolled release of the rope from the coil as the coil rotates momentarily faster than the rope can be fed into the rope to be formed.

In prior art solutions, flexible members of elevators, such as ropes, are individually mounted with a release device designed to prevent the free rotation of the rope by the retractor by spring force. Hereby tightening the spring achieves greater friction and prevents the rope from loosening from the coil. It is further known that the assistant brakes the coil, for example, manually or by means of an auxiliary device.

However, there are significant drawbacks to the prior art. Adjusting the discharge device described above is difficult and it often happens that a flexible member, such as a rope, is discharged too quickly or not at all. In addition, for example, the simultaneous disassembly of ropes is difficult with known devices. This makes the installation of the rope more difficult and time consuming. A further problem is the need for said mounting brackets, since the mounting brackets have no other use. However, there is a significant need for mounting brackets during installation, as there are several elevator models and many elevators are often installed at the same time. Storing and transferring said mounting brackets from storage to site and back to storage is both expensive and environmentally damaging. It is an object of the present invention to overcome the above drawbacks and to provide an inexpensive, environmentally friendly, reliable and easy-to-implement arrangement for mounting a flexible member such as a lifting member, a traction member or a power and data cable in an elevator. The lifting and drawing means may be, for example, a belt or a rope. Another object of the invention is to provide an environmentally friendly flexible body mounting kit that can be recycled after use. The method according to the invention is characterized by what is stated in the characterizing part of claim 1 and the arrangement according to the invention is characterized by what is described in the characterizing part of claim 9. Further, the mounting kit according to the invention is characterized in what is set forth in the characterizing part of claim 14. Other embodiments of the invention are characterized by what is stated in the other claims.

Inventive embodiments are also disclosed in the specification of this application. The inventive content contained in the application may also be defined otherwise than as set forth in the claims below. The inventive content may also consist of several separate inventions, especially if the invention is considered in the light of its expressions or implicit subtasks, or in terms of the benefits or groups of benefits achieved. In this case, some of the attributes contained in the claims below may be redundant for individual inventive ideas. Similarly, the various details presented in connection with each embodiment of the invention may also be used in other embodiments. Furthermore, it can be noted that at least some of the sub-claims can be considered as inventive as such, at least in appropriate situations.

The invention provides considerable advantages. Thus, the weight of the coil and the flexible member, such as the rope, ensures a reliable braking force. Because the rate of discharge of a flexible member such as a rope from the coil may be, for example, about 10 m / s, or even more during installation, the coil must stop reliably as soon as the flexible member is discharged. When the coil is lowered to the bottom of the packing box, the rotational force to weight ratio is generally substantially constant during braking.

It is also an advantage of the solution according to the invention that the packing box of the flexible member acts as a mounting bracket when the flexible member is unwound to its location. This eliminates the need for extra mounting brackets, their storage locations and the need to transport them between the installation site and the storage site, as the packing box itself also acts as an installation bracket.

A further advantage is that the said flexible members are kept in a packing box at all times in a well protected from moisture and dust, which does not need to be opened before installation. It is also an advantage that both the coils and all the structures needed to protect the coils and to re-position the flexible member are recyclable and environmentally friendly. A further advantage is that the coil according to the invention is very quick to implement, since no separate mounting brackets are needed.

In the following, the invention will be explained in more detail by way of example with reference to the accompanying simplified drawings, in which Fig. 1 is an oblique top and side view of one mounting kit according to the invention, Fig. 2 is a side and sectional view; one installation package according to the invention with the coil in its second position, Figure 4 is a front view of one installation package according to the invention and Figure 5 is a side view of the side wall of the packaging box of the invention package.

The idea of the solution according to the invention is that a flexible member 2, such as an elevator bracket, a lifting member, a pulling member or a power and data cable, is wound on a coil 6 for installation at an installation site comprising at least a packing box 1 containing a flexible member 2 As a support, lifting and pulling member, the flexible member 2 is, for example, a belt or rope, which rope preferably has a substantially small diameter, i.e. a so-called. a thin rope, e.g., about 3-8 mm in diameter, suitably, for example, about 4 mm. The packing box 1 provides storage and transport protection and furthermore, during installation, rotates the reel 6 in place to form an installation rack during installation, eliminating the need for a separate mounting bracket to rotate the reel 6 in place. In practice, such mounting kits are placed on a level in the building, such as a floor level or floor of an elevator shaft or engine room, during the elevator installation step, a plurality of flexible members 2 and coil 6 are pulled open to the elevator system, e.g.

Fig. 1 is an oblique top and side view of an installation kit according to the invention, comprising at least a packing box 1 and a reel 6 within which a flexible member 2, such as an elevator bracket, lifting member, pulling member or power and data cable, is mounted. The packing box 1 comprises at least a lid, a base, a front wall 1a, a rear wall and side walls Ib, and at least both the bottom and side walls Ib are preferably reinforced. Each side wall Ib has an opening 3 in two directions obliquely downwardly, the first end of which is inclined downwardly towards the front wall 1a of the packing box 1 and the other end is inclined downwardly towards the rear wall of the packing box 1. The coil 6 is adapted to rest on the aperture 3 in the side walls Ib of the axle strip 7. The apertures 3 serve as mounting means and a rotary support for rotatably supporting the coil 6 inside the packing box 1. Instead of the apertures 3, the rotational supports for the rotation axis 7 may also be completely inserted into the inner surface of each side wall Ib within the packing box 1. Hereby, said inner surfaces may have grooves in the form of an aperture 3 which, however, do not extend through the side wall Ib outside the side wall Ib. In addition, the front wall 1a of the packing box 1 has an opening 5 having an openable lid part 4 which is opened during the installation of the flexible member 2 so that the flexible member 2 can be released from the reel 6 to its location.

The entire installation kit is made from environmentally friendly recyclable materials that can be recycled after the flexible member 2 is installed. The packaging box 1, which is substantially rectangular in shape, is made of a material made of vegetable fibers, preferably wood fibers, such as cardboard, for example corrugated board, which is folded over several layers as needed. Correspondingly, the body of the coil 6 is also made of vegetable fibers, preferably wood fibers or other types of cardboard, or also wood. In addition, the shaft 7 of the reel 6 is also made of vegetable fibers, preferably wood fibers, for example, pressed together, or the shaft may also be a shaft turned from wood.

Figures 2 and 3 show a side view and a sectional view of one mounting kit according to the invention. In the situation of Fig. 2, the reel 6 is in its first position within the packing box 1 off the inner base 8 of the packing box, in which case the reel 6 is substantially freely rotatably supported on the first end of the openings 3 from the shaft 7. This position allows the reel 6 to rotate substantially freely. However, if braking is required for the rotation of the coil 6, the coil 6 may be positioned in its second position as shown in Fig. 3 such that the shaft 7 of the coil 6 is moved to one end of the opening 3 which is below the first end. In this case, the outer circumference of the reel 6 hits the inner base 8 of the packing box 1, whereby the friction caused by abrasion contact appropriately retards the rotation of the reel 6.

Fig. 4 is a front view of one mounting kit according to the invention, viewed from the front of the packaging box 1. Fig. 4 clearly shows how the ends of the axis of rotation 7 of the reel 6 extend in each direction out of the side walls Ib of the packing box 1, supported by the openings 3 in the side walls Ib which support and rotate the axis of rotation 7.

Fig. 5 is a side view of the side wall Ib of the packaging box 1 according to the invention. The opening 3 in the sidewall Ib supporting the axis 7 of the reel 6 is bifurcated, each of which branches obliquely downwards. The first end 3a of the opening 3 is directed obliquely towards the front wall 1a of the packing box 1 and the second end 3b of the opening 3 is directed substantially at an angle downwards towards the rear wall of the packing box 1. The first end 3a of the opening 3 is shorter than the second end 3b, so that the first end 3a of the opening 3 is farther from the inner base 8 of the packing box 1 than the second end 3b of the opening 3. The distance of the opening 3 from the insole 8 is dimensioned relative to the diameter of the reel 6 so that when the shaft 7 of the reel 6 is at the first end 3a of the opening 3a, the outer circumference of the reel 6 is detached from the inner base 8 to the insole 8 of the packing box 1 to provide the braking effect of the rotation of the reel 6.

In the method and arrangement of the invention, one or more packing boxes 1 with coils 6 are placed parallel to a building level, such as a floor level, elevator shaft floor or engine room floor, during installation of flexible members 2 and all flexible members 2 1 inside the stationary rotatable coils 6, for example, by pulling the flexible member 2 out of the packing box 1 by the elevator's own machinery or other suitable machinery.

Before removing the flexible member 2 from the packaging box 1, the axis of rotation 7 of the reel 6 is placed at the first end 3a of the opening 3, after which the reel 6 is rotated at the first end 3a of the opening 3 by pulling the flexible member 2 out. If necessary, the rotation of the reel 6 is inhibited by moving the axis of rotation 7 of the reel 6 to one end 3b of the opening 3 and allowing the outer circumference 6a of the reel 6 to rotate against the insole 8 of the packing box 1.

The coil 6 is rotated within the packing box 1 on the packing box 1 substantially throughout the feeding of the flexible member 2. As the reel 6 rotates at the first end 3a of the opening 3, the reel 6 is supported by the shaft 3 through its axis 7 and the side walls Ib of the packing box 1, and the reel 6b is rotated by the inner base 8 of the packing box 1 after feeding the members 2 and with the coils 6 empty, the packaging boxes 1 with the coils 6 and the shafts 7 are recycled.

It is also to be noted that the various solutions and features described above may be inventive features with one or more other features of the invention.

It will be apparent to one skilled in the art that the invention is not limited to the above examples, but may vary within the scope of the following claims. Thus, for example, the shape, construction and operation of the packing box and the coil and the axis of rotation may be different from those described above.

It will also be apparent to one skilled in the art that, if necessary, the coil can be braked by other means than by letting the outside of the coil scrub the inside of the packing box. The sidewalls of the packing box may, for example, have holes at a suitable position, into which can be inserted cardboard or wooden pins, against which the reel may be rotated by suitable displacement.
