Abstract

The reel (10) has a central portion (14) and lateral parts (16, 18) arranged at the central portion. The central portion is provided for receiving respective elongated material. Measured width of the reel is influenced by changing configuration of the central portion along a rotational axis of the reel. Multiple props (12) are rotationally and symmetrically arranged at the central portion over the rotational axis of the reel, where each prop comprises a joint unit (20) and is hingedly connected with the lateral parts. An independent claim is also included for a reel system.

Description

The invention relates to a reel for winding and unwinding of elongated materials such as ropes, wires, cables, chains, belts, hoses, yarns and the like. The invention further relates to a coiler with at least one such reel or for at least one such reel.

Reels of the type mentioned are known per se. Thus, e.g. Electric cables are supplied on so-called cable drums and when using the electric cable suitable lengths of such a cable drum, which is also a reel in the sense of the description presented here, unwound or withdrawn and cut to length.

A disadvantage of known reels, in particular reels in the form of cable drums, drums for hoses, chains or any other reeling material, however, is the comparatively large space required, which is associated with the dimension of the respective reel. This space requirement is particularly disturbing when the originally located on the reel material is removed and the reel must be stored or transported until disposal or return to a manufacturer or intermediary.

From the JP 2004 043 176 A a cable drum with disc-shaped, full-surface side parts is known, between which there is a central part with a plurality of each hinged struts. Also the US 5,467,939 B shows such a cable drum with a central part with a plurality of hinged struts. The US 3,791,606 B finally shows a cable drum with a central part with a plurality of hinged struts, wherein the side parts in a central portion four spokes and in an adjoining outer portion having a significantly higher number of spokes and wherein the hinged struts attack on each of the spokes located in the outer portion of the side parts and protrude from there in the folded state over the outer periphery of the side parts.

An object of the present invention, in particular, starting from this prior art is to provide a further embodiment of a reel whose width measured along a rotation axis of the reel can be influenced by changing a configuration of the middle part, in particular by folding a plurality of struts forming the central part executed and hinged to the side parts of the reel is connected.

This object is achieved with a reel of the type mentioned with the features of claim 1. This is in a reel for winding and unwinding of elongated materials, the reel has a central part and two laterally arranged on the middle part side parts and wherein the central part is provided for receiving the respective elongate material, wherein a measured along an axis of rotation of the reel width the reel can be influenced by changing a configuration of the middle part, in that the middle part has a plurality of struts (center struts) arranged rotationally symmetrically around a rotation axis of the reel, and wherein each strut comprises a middle joint and is articulated with the two side parts is provided, provided that each spoke in the radial direction has a plurality of stop points for releasably fixing a strut with the spoke and that each strut is releasably connected on both sides to a respective spoke at an abutment point with the respective side part.

The invention is based on the recognition that the side parts of a reel are those elements which on the one hand determine the dimension of the reel with respect to a hull contour and on the other hand are not easily modifiable in order to change a size of the reel. On the basis of this, the invention is based on the knowledge that a size of the reel can be influenced very well with regard to an envelope volume is, if a change in a configuration of the central part along a rotational axis of the reel measured width of the reel is influenced overall. For such an influencing of the width of the reel or the longitudinal extent of the central part along the axis of rotation is for example a telescoping of the central part into consideration. An alternative possibility for influencing the width of the reel measured along the axis of rotation of the reel is that the middle part is designed to be foldable, as is generally known in the prior art. In both cases, ie by telescoping or folding the middle part, the length of the middle part along the axis of rotation changes, ie the width of the reel as a whole along the same axis of rotation. The fact that the width can be changed, ie reduced, reduces the envelope volume of the reel considerably, for example from a width of initially forty centimeters to a minimum width determined by the thickness of the two side parts. Several such folded or folded reels can be stacked side by side or on top of each other. A plurality of such folded together reels takes up no more space than a previous reel. Thus, if, for example, at a mounting location where cable supplied on cable drums are used, after the cables have been installed several reels, ie cable drums, have to be removed, a transport vehicle with sufficient space for essentially the sum of the envelope volumes of the cable drums has hitherto been necessary. With the reel according to the invention, especially with a reel with a hinged middle part, in which the height or width of the folded reel corresponds to the height or width of the two side parts or at least substantially the height or width of the two side parts, only a fraction of the results previous space requirements. This results in cost savings during transport and storage. In addition, the reel is sufficiently stable to accommodate even heavy reeling materials such as larger diameter electric cables or power cables and the like or steel cables, iron chains and so on.

In one embodiment of a reel, in which the configuration of the middle part can be influenced by the fact that the middle part is designed to be foldable, the middle part has a plurality of struts arranged rotationally symmetrically about an axis of rotation of the reel, wherein each strut comprises a central joint and is articulated to the two side parts. When folding the reel, the struts can be pivoted with its central joint inwards or outwards, ie in the direction of the axis of rotation or away from the axis of rotation, wherein the articulated connection of the struts with the side parts at the outer ends of the struts the mobility in the middle joint allowed. Such kinematics with exactly three joints for each strut is particularly easy to produce. In principle, it is also possible to carry out only individual struts in this form and to provide for other, rigid struts a detachable connectivity to the reel, in particular its side parts. In this respect, the wording according to which each strut comprises a middle joint and hinged to the side parts is to be interpreted as meaning with each strut those struts which in the collapsed condition of the reel are still connected to same as before the connection in use , that is, in the non-merged state has existed.

The advantage of the embodiment of the collapsible reel according to the invention is that the diameter of the central part is variable. By having each spoke in the radial direction a plurality of abutment points for releasably fixing a strut (or a rigid strut) hinged at its central joint to the spoke, each strut can be attached to one of these abutment points. By choosing the attachment points results in the diameter of the middle part. If attachment points are used, which are located on the spokes in the radial direction on the outside, resulting in a larger diameter of the middle part. If stop points are used which are located on the spokes in the radial direction further inside, correspondingly results in a smaller diameter. In this way, the diameter of the middle part can be individually tailored to the respective winding material, because in particular special cables may not be wound arbitrarily tight, for example, so that for such a winding material on the folding reel the struts are attached to the spokes in a configuration that has a central part with a larger diameter to the result. Furthermore, for example, hoses, especially plastic hoses, due to the material properties difficult to be wound on a central part of a reel with a small diameter, so that also offers an adjustment of the diameter of the central part of the reel in the direction of a larger diameter for such a winding material. Other winding material, for example, ropes and normal electric cables, can also be wound on middle parts with a small diameter, so that this is the middle part is set to a small diameter in order to apply the largest possible amount of winding material on the folding reel can. The wording according to which a strut is detachably connected to a spoke therefore does not mean every basically releasable connection, but rather such releasable connections, which allow a change in the diameter of the middle part of the reel with the release of the connection and the subsequent restoration of the connection.

By each strut is connected on both sides releasably connected to a respective spokes at an abutment point with the respective side part, the described adjustability of the diameter of the central part of the folding reel is at any time possible, at least when there is no winding material on the reel that the adjustment of the diameter prevented. Specially empty reels can therefore be individually set to the required diameter before being put into use. The two-way detachable connection of the struts on the spokes also has the advantage that can be removed by solving individual compounds of the side parts of the folding reel and winding material, which for example due to such a configuration in the delivery state is still present in the form of a ring (for example Hoses, cables, ropes and the like), without first unwinding the ring and having to wind the winding material on the reel, can be placed directly on the middle part of the folding reel. Subsequently, the previously removed side panel is attached again and the winding material can be unwound from the reel in the usual way. For combining winding material, which is already present in the form of a ring, with the folding reel this is usually placed after removing one of the side panels with the remaining side part on a surface, so that the middle part projects upwards and the ring is placed directly on the middle part can be. In this position, the removed side part can be easily re-attached.

Advantageous embodiments of the invention are the subject of the dependent claims. This used backlinks point to the further development of the subject matter of the main claim by the features of the respective subclaim; they should not be construed as a waiver of obtaining independent, objective protection for the feature combinations of the dependent claims. Furthermore, with a view to an interpretation of the claims in a closer specification of a feature in a subordinate claim, it is to be assumed that such a restriction does not exist in the respective preceding claims.

When the hinged connection with the side members is on a side facing the central part or edge of the respective side part, pivot the two from the center joint outgoing portions or segments of the struts when folding the reel from the fixed by the articulation with the side fulcrum inwards the side parts, ie above or between the spokes of the side parts. In this way, the space requirement of the folded reel on the footprint of the two side parts or at least substantially reduce the space requirement of the two side parts, because the merged middle part is completely folded into the two sides and corresponding to the resulting for the collapsed reel envelope volume no or only a marginal role.

In a further embodiment it is provided that each strut or at least a plurality of struts has a thickness sufficient that the middle joint is attached to a lower side of the strut and that the profile of the strut remaining above the middle joint serves as a stop for the mobility of the middle joint acts. In such a configuration, a reel is immediately ready for use after unfolding without further interventions, such as a locking of individual struts or the like, would be required. In order to take a present in the folded state reel in use, it is therefore sufficient to move the two side parts apart, so that an increasing extension of the initially collapsed struts takes place, the maximum extension of the initially collapsed struts is achieved when the profile of the strut on both sides of the middle joint comes into contact and thus so there is a stop that limits the mobility of the central joint. This stop also prevents any bending of any strut, so that when winding the respective reeling material, even with heavy materials such as heavy power cables, heavy wire cables or heavy iron chains, the integrity of the central part and its function as a hub for each reeling material readily ensured is. In a particular embodiment, it is provided that the struts also include an angle less than one hundred and eighty degrees in the unfolded state, that is, the two segments of the struts are not in the same line even in the unfolded state. This avoids the above-mentioned sagging, but above all allows easy folding of the folding reel, because in a movement of the two side parts to each other with respect to the center joint of the struts no dead center is overcome and the struts directly to the relative movement of the side pieces to fold up. For example, the reel can be tilted sideways so that it collapses when dropped onto the ground.

Of course, the nature and strength of the profile of the struts of the particular situation of use is adjusted, so that a reel for heavy iron chains not only in their dimensions, but also in the material thickness or the type of profiles used by a reel for example nylon ropes or garden hoses different. The fact that each strut is releasably connected on both sides to a respective spoke at an attachment point with the respective side part, however, the configuration of the middle part can be adapted quickly to different load situations. By using heavier struts, which are larger in material thickness in particular, as the central part, the reel can be quickly converted for use in winding heavy iron chains, for example. If then on the same reel light winding material, such as ropes or the like, to be applied, smaller-sized struts can be used again. The detachable connectivity of the struts with the both sides also opens the possibility of using struts of different lengths, for example lengths that result in a width of the reel in the order of forty centimeters, ninety centimeters and one hundred and forty centimeters, etc., so that the reels work well in a coiler Distance of the supports included therein in the order of fifty, one hundred, one hundred and fifty etc. centimeters are usable. For a large amount of reelable material struts come into consideration, which have a greater length in the unfolded state. By such different lengths and / or different heavy struts, although slightly increases the storage costs. The advantage of the small footprint of the empty reels remains, however, and there is the additional advantage that the reels can be configured individually for each need, so that, for example, with full reels no unnecessarily wide reels must be transported and that the weight fraction of When reeling full or empty reels, reels are never unnecessarily large.

In one embodiment of the reel, a pin guided at an abutment point through the free end of the strut and through the spoke acts as a hinged connection between the strut and the respective side member. Such a pen can be attached quickly and easily. As stop points for the struts so matched to the diameter of the pin matched holes in the spokes. The pin thus not only acts as a hinged connection between the strut and the side part, but also fixes the struts on the side part and the respective spoke. In a preferred embodiment of such an articulated connection, the pin can be fixed with a securing device in the attached state. As a pen then, for example, a spring pin or spring split into consideration. Such a spring plug unites in one piece the pin and the securing device, so that the securing device can not be lost. Otherwise, a pin comes into consideration, which has a head on the side and on the opposite side a bore for insertion of acting as a security device cotter pin or the like.

When each side member has radially oriented spokes and at least one of these spokes has at least one recess for passing one end of an elongated material respectively on the reel, the or each recess provides a means for defining one end of the respective wound material to unintentionally unwind or to avoid unwinding. In a variant of this embodiment it can be provided that at least one spoke in the radial direction has a plurality of recesses of the above type, so that depending on the amount of material still on the reel each have a recess in a vicinity of the currently topmost layer of the respective material can be used, so that a sometimes unfavorable lots in the wound material is avoided and the rest of the material located on the reel can be determined by passing the end through the nearest topmost position of the respective top layer. In a particular embodiment, it is also contemplated that a plurality of spokes or all spokes in the radial direction have a plurality of recesses of the type mentioned above and / or that the radial distances of such recesses are alternately arranged on, for example, two or three spokes, so that on the one hand sufficiently large Recesses for passing ends of the respective materials in different thickness are possible without jeopardizing the structural integrity of the spokes, but on the other hand also a recess is selectable, which is maximally adjacent to the current topmost layer of the wound material, so that with the passing the end by a recess a clamping of the material still on the reel is possible.

When each side part has a plurality of radially oriented spokes or segments functioning as spokes, in one embodiment of the reel, it is provided that the struts of the middle part are uniform over an inner diameter of the side parts, ie a diameter at a height of the articulated connection between struts and side parts, are distributed. Then there is the possibility that there is at least one strut between each two spokes or two each acting as spokes segments. Such an alternating arrangement of struts and spokes / segments allows the folding of the middle part in a gap resulting between every two adjacent spokes. Between each two spokes more than one strut, so for example two or three struts, can be provided.

An alternative embodiment with a uniform distribution of the struts on the inner diameter of the side parts is characterized in that in the circumferential direction each have a strut and a spoke in the same radial direction, so when folding the middle part of the segments of the struts against or over the spokes fold. Such a paired arrangement of struts and spokes allows the midsection to be folded over the spokes.

An embodiment of the reel with a uniform distribution of spokes and struts is characterized in that the reel in their side parts, e.g. three, four or six spokes and in its central part has three, four or six struts, so that on the side parts in the region of the articulated connection between struts and side part either an alternating sequence of struts and spokes or a paired arrangement of struts and Spokes yields. Other numbers of spokes / struts are also conceivable, e.g. five or more spokes and struts. It is also conceivable to provide a plurality of foldable struts between each two adjacent spokes. Likewise, it is conceivable to provide individual struts in a radially identical direction, each with a spoke, wherein one or more further spokes may be located between such spokes. The same applies vice versa for the number of struts, so that individual struts are arranged in the same radial direction with one spoke and there are between them further hinged struts or possibly also non-hinged and instead removable struts.

In a further embodiment of the hinged reel, each spoke has a U-shaped profile, each strut also having a U-shaped profile or a U-shaped profile in the form of a hat profile or the like, and each of the segments of the strut connected by the central joint with its U-shaped profile when folding the middle part over the U-shaped profile of a spoke works. By cutting each strut over a spoke, resulting in the folded reel on the side parts free circle segments, which facilitate the handling of the folded reel, because in the region of these free circle segments can be easily touched. This creates an important difference to the configuration of a hinged reel, in which the collapsed struts fold into a space between each two spokes, because there the struts flatten into those circle segments of the side parts, which are now free.

In a hinged reel, which has recesses in its spokes for passing one end of the respective winding material, the struts folding over the spokes cover these recesses, so that it is reliably avoided that objects inadvertently enter these recesses.

The invention further relates to a coiler with at least one reel or for at least one reel as described here and below. The coiler has at least two vertical or vertical attachment provided with supports formed therein or attached to recordings for an inserted or insertable into a reel axis. The axis has on both sides at their ends a constriction and the constriction is limited at least at one end of the axis of at least twice or even three or four times as large as the diameter of the axis or the like discs. The vertical support is a profile element or comprises a profile element, formed therein or attached thereto receptacle absorbs the constriction of the axis, wherein the right and left of the constriction larger diameter of the axis limited on the one hand, a horizontal mobility of the axis in the support, said at least one side significantly larger than the diameter of the axis running discs or the like abut each other on the profile of the support and so on the other hand reduce any otherwise given pivoting movement of the axis to the support to a minimum. Such a configuration of the axles in connection with the supports and the receptacles formed therein or attached thereto causes two supports connected by at least one axle of the type described above to stabilize one another, because they are distinct relative to the diameter of the axles larger discs a permanent right-angled or at least substantially perpendicular orientation of the axes to at least that support on the profile of these discs, guaranteed. This makes it possible to erect such a coiler quickly. For the supports horizontal feet may be provided, which may be mounted on the ground, so for example screwed to avoid, for example, when unwinding the material a tilting of the coiler in the pulling direction. In any case, a tilting of the coiler in the direction of the longitudinal extent of the axes attached thereto is avoided by the special configuration of the axes. Possibly. can also be provided in the axes that they have not only on one side, but on both sides right and left of the constrictions there discs for stabilizing the coiler as described above. The constriction does not necessarily intervene in the solid material of the respective axle. The constriction can also result from the two adjacently arranged discs, so that the constriction is also the area located between two such discs at one end of the axle and, for example, rings or the like at the other end of the axle. If the discs are designed as round discs, there is a favorable solution with regard to the handling of the respective axes, in particular with round discs compared to square or square discs, an otherwise possibly existing risk of injury at the corners of such discs is avoided. A particular embodiment is characterized by the fact that the disc, whether in otherwise round or square shape, is angled on one side, so that the angle is applied at a mounted on a support axis at a front edge of the support profile. The angled disc provides additional stability and rigidity, such as with an L-profile, and such a disc is particularly well suited for perpendicular or at least substantially orthogonal alignment of the axle with the respective support.

A particular embodiment of the coiler unit is characterized in that horizontal outriggers are connectable to the vertical supports, each boom having means for combining with at least one of the supports formed in the supports or mounted in the supports. Thus, at the supports are not special Action required if attaching one or more outriggers is desired. As a means for combining with at least one of the supports formed in the supports or mounted on the supports recordings is basically a lateral pin or a pair of lateral pins on the boom into consideration. The boom can be designed overall L-shaped, with a provided for horizontal alignment long leg and a short leg, which is supported either on the respective vertical support of the coiler (in the attached state downwardly directed short leg) or at its end or in the A portion of one end comprises means for combining with at least one of the receptacles formed in the posts (upwardly directed short leg). In a mounted in an attached state up short leg means for combining with the receptacles formed in the supports can be omitted in the region of the joint between the long and the short leg of the boom, because such a boom virtually depends on its short leg and at least in the area the joint between the long and short leg is supported on the support. In any case, a secure, fast and easy to produce connection between the boom and one support of the coiler system is possible in each described configuration. Two cantilevers can be used to mount between them, eg in the form of a tube, an iron rod or the like, an axle on which reels as described above, but also known reels or cable drums can be attached. While the reel system with its provided between the supports axis quasi initially only in two dimensions with reels or reels known per se and cable drums can be equipped, the possibility of using the coiler, each with a pair or more pairs of arms in a third dimension, so that extends the amount of receivable reels is significantly increased.

A special embodiment of the coiler is characterized by at least two horizontal arms and a worktop mounted thereon. The arms are readily usable for placing a countertop. Possibly. the worktop can be detachably connected to the arms, for example by screwing or the like, but also, for example, only intermittently, for example by Attaching a screw clamp or the like. In any case, the surface of the worktop provides a workplace for the coiler operator serving the workstation can be changed at any time in its position by the at least two booms are attached to a different location of the coiler and the worktop is positioned there. If the provided for receiving a reel or cable drum axes, which simultaneously cause, as described above, a stabilization of the coiler perpendicular to a take-off direction, a length of, for example fifty centimeters or the like, the distance between the supports of the coiler from a the coiler-working mechanic, especially a worker using the worktop, are used as a guide when cutting material by the respective material along the width of the coiler each one, two, three or more supports and at longer lengths in the opposite direction ,

Fig. 1 shows a representation of an embodiment of a reel 10 according to the invention. This is intended for winding and unwinding elongated materials such as ropes, wires, cables, chains, hoses, tapes, yarns, etc. The reel 10 comprises one of a plurality of struts 12 - here four struts 12 - formed central part 14 ( Fig. 2, Fig. 3 ) and in each case laterally on the central part 14 arranged side parts 16, 18. In the side parts 16, 18 (wheel) openings are provided for introducing an axis in the middle.

The illustrations in Fig. 2 and Fig. 3 each show a reel 10 ready for use or substantially ready for use, ie with unfolded or at least substantially unfolded middle part. An axis of rotation of the reel 10, not shown in the drawing, runs in the illustrations in FIG Fig. 2 and Fig. 3 approximately horizontally in the area of the respective image center. The difference between the representations in Fig. 2 and Fig. 3 consists in the larger diameter of the central part 14 at the in Fig. 3 shown configuration of the reel 10. The adjustment of the diameter of the central part 14 will be described in detail below.

The reel 10 is characterized in that a measured along the axis of rotation of the reel 10 width of the reel 10 can be influenced by a change in a configuration of the central part 14. In the illustrated embodiment, the configuration of the middle part 14 can be influenced by the fact that the middle part 14 is designed to be foldable. For each strut 12 includes a middle joint 20 and further, each strut 12 is pivotally connected to the two side parts 16, 18, namely each having a spoke 24 of the two side parts 16, 18. As an articulated connection acts here a spring pin 22, the exemplary of Any shape of pin or the like, so for example the bolt of a screw is shown. Overall, the central part 14 comprises a plurality of such struts 12, which are arranged rotationally symmetrical about an axis of rotation of the reel 10.

The articulated connection of the struts 12 with the side parts 16, 18 is on a side facing the central part 14 or edge of the respective side part 16, 18, so that when folding the reel 10 (FIG. Fig. 1 shows the reel 10 in a snapshot when collapsing / folding) the two outgoing from the central joint 20 sections of the struts 12 in an area inside the side panels 16, 18 can be pivoted, namely here on the spokes 24. An outer peripheral surface of the side parts 16, 18 is closed by a circular tube formed so that the reel 10 can be rolled on the one hand slightly on the ground and on the other hand in a mounted on an axle on a support frame, such as a coiler as described below, configuration can be easily rotated by the outer circumferential tubes 16 of the side parts , 18 or one of the outer circumferential tubes is touched.

In the illustration in Fig. 1 , but better still in the illustrations in Fig. 5 to Fig. 9 , It can be seen that each strut 12 is designed with a U-profile, in this case a so-called hat profile, and in any case has a strength sufficient that the central joint 20 is formed or attached to an underside of the strut 12 and that above the middle joint 20 remaining profile of the strut 12 acts as a stop for the mobility of the middle joint 20. As far as shows Fig. 4 a strut in the unfolded state and Fig. 5 the unfolded strut 12 in a view from above, wherein the in Fig. 5 the viewer facing surface portions of the profile of the strut 12 together with corresponding profiles of adjacent struts 12 form the winding surface of the central part 14 for winding up the respective elongate material. Fig. 6 shows a leg of a strut 12 in a side view, wherein it can be seen that the center joint 20 can be easily formed by the circular bending of an end portion of the profile, wherein in the thus bent profile sections as a hinge axis in Fig. 5 dashed lines marked bolt is inserted. Fig. 7 shows a cross section through the in Fig. 6 shown segment of the strut 12. It can be seen that in its basic contour U-shaped profile, which is supplemented here by the shutdowns on the legs of the U-shaped contour to a hat profile.

Especially the representation in Fig. 4 shows that with an unfolded strut 12 above the middle joint 20, the profiles of the struts 12 abut each other and act as a stop for the mobility of the central joint 20. The hinged struts 12 thus provide sufficient rigidity to interact with the hub Midsection 14 different types of reelable material, so ropes, wires, cables, chains, hoses, etc. to be able to record.

Fig. 8 is an isometric representation of in Fig. 4 shown in a side view strut 12th Fig. 9 is an isometric view of a partially folded strut 12, so a representation of a configuration of a strut 12, as it results when folding the folding reel 10.

Fig. 10 shows the reel 10 in a collapsed state. It can be seen that the struts 12 are folded together at the middle joint 20 and that in this case the two segments of the struts 12 connected to the middle joint 20 come to lie on one another or come to lie substantially opposite one another. A height (or depending on the viewing direction, a width) of the reel 10 in the folded state is only or at least substantially determined by a height or width of the two side parts 16, 18, because in the folded state, the two side parts 16, 18 face each other come or at least essentially come to rest on each other. This is achieved in that each spoke 24 has a U-shaped profile and each strut 12 also has a U-shaped profile, here a hat profile with a U-shaped base profile, whose width is chosen so that the U-profile of Strut 12 fits positively on the U-profile of the respective spoke 24. Each of the connected by the center joint 20 segments of the strut 12 thus works with its U-shaped profile when folding the middle part 14 on the U-shaped profile of a spoke 24. Alternatively, a reverse, not shown configuration is conceivable in which the in the Figures open to the outside U-profile of the spokes 24 in the direction of the central part 14 is open and the struts 12 with a matching U-profile in the U-profile of the spokes 24 fold.

When displayed in Fig. 10 , which, as far as one of the side parts 16, 18 is concerned, can also be understood as representing a side view of the reel 10, it can be seen that the spokes 24 in the side members 16, 18 are radially aligned and evenly distributed and one for insertion of a Axis provided Pipe section go out. The spokes 24 are suitably fixed to this pipe section and to the outer ring of the side parts 16, 18, for example, welded.

This results in a reel 10 for winding and unwinding of elongate materials with a central part 14 and in each case one side of the middle part 14 arranged side part 16, 18. Each side part 16, 18 has a plurality of radially oriented spokes 24. Shown is a reel with four spokes 24. Similarly, reels 10 with three, five, six or more spokes 24 are conceivable. Preferably, the number of spokes 24 depends on the size of the reel 10, so that, for example, three spokes 24 for reels 10 with an outer diameter of the side parts 16, 18 in the order of fifty to sixty centimeters come into consideration. The configuration of reel 10 with four spokes 24 shown in the figures is therefore applicable, for example, to reels 10 having an outside diameter of the side parts 16, 18 of the order of ninety to one hundred and twenty centimeters. Five spokes 24 are contemplated for reels 10 having outside diameters of the side members 16, 18 of the order of one hundred and twenty to one hundred and eighty centimeters. Six spokes 24 are finally contemplated for reels 10 having an outer diameter of the side members 16, 18 of the order of one hundred and eighty centimeters and more.

The middle part 14 located between the side parts 16, 18 and the spokes 24 there is provided for receiving the respective elongate material and thus acts as a winding core. The middle part 14 comprises a plurality of struts 12 arranged rotationally symmetrically about an axis of rotation of the reel 10. Each strut 12 has a middle joint 20 and is articulated to the two side parts 16, 18 by means of a spring plug 22 or the like. For this, each spoke 24 has a plurality of stop points in the radial direction for releasably fixing a strut 12 to the spoke 24. In the embodiment of the reel 10 shown in the figures, these abutment points are bores 26 through the profile of the spoke 24, into each of which a spring pin 22 or the like can be inserted. In this way, each strut 12 is detachably connected on both sides to a respective spoke 24 at an abutment point with the respective side part 16, 18.

The spring connector 22 engages with its acting as a rotation axis for the respective strut segment straight portion through the bore 26 in the spoke 24 and through corresponding holes in the distal end of the central joint 20 of the strut 12 (the lateral holes in the strut 12 are particularly good in Fig. 4 visible). With the resilient portion of the spring pin 22 engages by recesses 28 formed in the spokes 24, which are otherwise also provided for the insertion of material ends, namely cable ends or the like. The resilient portion of the spring connector 22 acts as a securing device, with which the spring connector 22 in total, but especially its effective as an axis for the pivoting movement of the strut segment straight section in the attached state is fixed. Instead of a spring connector 22 may be used for articulating the struts 12 with the side members 16, 18 as well as the bolt of a screw which is guided in the bore 26 in the spokes 24 and corresponding holes in the struts 12. A screw head and a nut or the like mounted in the inserted state function as a securing device with which the screw bolt can be fixed in the attached state.

Characterized in that each spoke 24 in the radial direction a plurality of abutment points - here the holes 26 - for releasably fixing a strut 12 with the spoke 24 and that each strut 12 on both sides releasably connected to a respective spoke 24 at an abutment point with the respective side part sixteenth , 18 is connected or connectable, the diameter of the core acting as a winding core for each material to be wound middle part 14 can be adapted to the respective needs ( Fig. 2 : small diameter; Fig. 3 : larger diameter). In the embodiment shown in the figures, each spoke 24 in the radial direction four as stop points for the struts 12 acting holes 26. Thus, each strut 12 can be mounted in four radially different positions. This results in at least four possible different diameters of the struts 12 formed with the middle part 14. The number of stop points / holes 26 on the spokes 24 depends on the diameter of the respective side part 16, 18, so that more than in the figures shown acting as stop points holes 26 come into consideration. With the use of spring plugs 22 can be the connection of the struts 12 with the spokes 24 solve quickly and easily and later restore, so that a change in the diameter of the central part 14 can be achieved in a very short time.

Due to the detachable connection between the spokes 24 and the struts 12, there is also the possibility that one of the side parts 16, 18 is removed from the reel 10, wherein the struts 12 remain connected to the other side part 16, 18. Then, for example, an electrical cable or the like delivered in the form of a ring (material ring) can be passed over the struts 12 still hinged on the remaining side part 16, 18, and then the previously removed side part 16, 18 can be replaced. Elongated material which is supplied in the form of rings, as is usually the case for electric cables, hoses and the like, accordingly does not need to be wound onto the foldable reel 10, but can be placed in the delivered state on the reel 10. This saves time and avoids damage to the respective elongate material.

In the illustrations in Fig. 1 and Fig. 10 It can be seen that the spokes 24 have at least one recess 28, here a plurality of recesses 28, which are provided for passing one end of a respective material (not shown) located on the reel 10. In various embodiments of the reel 10, namely reels 10 for different materials or different amounts of materials, a plurality of such recesses 28 may be provided on a spoke 24. Otherwise, the width of the recesses 28 is proportional to the size of the reel 10 or the size of the goods to be wound with the reel 10, so that eg a reel 10 for power cables with a diameter of several centimeters and a recess 28 with a corresponding Opening width is available.

Fig. 11 shows a coiler 30 with at least one reel 10 or for at least one reel 10 as described here, but which is also suitable for receiving other reels or cable drums. The coiler 30 initially consists of a A plurality (at least two) of vertical supports 32, which at its lower end have or can have a foot 34 for fastening, eg by screwing, to the floor. For receiving in each case a reel 10 or other cable drums each have an axis 36 is provided which is effective for stabilizing the supports 32 against each other, as will be described below.

Fig. 12 shows an enlarged view of an axis 36 and Fig. 13 a lateral view of a support 32. It can be seen that the support 32 distributed over its height, in particular at least from a certain height level, regularly distributed, a plurality of receptacles 38 formed in the support 32 has. The axle 36 has constrictions 40 on both sides at its ends, either by removing such a constriction 40 from the solid material of the axle 36 or by providing discs 42 or rings (not shown) laterally adjacent to a constriction 40 on both sides. It is essential that the diameter of the axis 36 in the region of the two constrictions 40 is placed on the width of the receptacles 38 in the supports 32. The disks 42 (or "plates") to the right and left of at least one constriction 40 located on the two outer sides of the axle 36 stabilize a shaft 36 mounted on a support 32 in an axle 36 mounted in its seats 38 in a right-angled or at least substantially right-angled manner Orientation to the respective support 32. In the in Fig. 11 and Fig. 13 illustrated embodiment of the supports 32 are U-profiles and the receptacles 38 are formed in the two legs of the U-profile. In another configuration of the supports 32 may also be provided that the receptacles 38 are mounted in a suitable form on the supports 32, for example by the receptacles 38 are formed in tabs, which in turn are attached to the supports 32. The receptacles 38 are recesses 38 directed downwards in the bottom direction, so that an axle 36 or a reel 10 attached to an axle 36 does not detach from the support 32 and from the receptacle when the wound material is removed and thus in the pulling direction 38 can solve. A possible embodiment of a receptacle 38 is in the enlarged view of a portion of the support 32 in FIG Fig. 14 shown and you can see that the recording 38 is designed finger-shaped, wherein a bottom portion of this finger-shaped receptacle 38 is provided for receiving the constrictions 40 of an axis 36.

It can be seen in the perspective view of the support 32 in Fig. 13 in that the receptacles 38 are formed in both legs of the U-profile of the supports 32, so that at one and the same height of a support 32 a right and a left-pointing axis 36 can be attached.

Fig. 15 shows a boom 44 for the coiler 30 in Fig. 11 and Fig. 16 , The boom 44 has a long and a short leg. The long leg of the boom 44 is oriented horizontally in the attached state. In the region of a joint of the long and the short leg, the arm 44 has means for combining with at least one of the receptacles 38 formed in the supports 32, eg a laterally projecting pin 46, bolt, pin or the like. Instead of a protruding on one side of the arm 44 pin 46 may be provided on both sides of such a pin 46, so that with a pair of such pin 46 both in the U-profile of the support 32 opposite receptacles 38 can be contacted. With the short leg, the boom 44 is supported on the support 32 in the attached state. The boom 44 has on a top of the long leg on a flat surface and in the long leg holes may be provided, for example, allow the insertion of rods, tubes and the like to a pair of such boom 44 cable drums, reels 10 or the like in store an additional level to the main plane formed by the supports 32 of the coiler 30 and thus increase the capacity of the coiler 30.

Fig. 16 shows to another use of the boom 44, namely for attaching a countertop 48. The countertop 48 can be placed on the long legs of at least two arms 44 or attached to these in a suitable manner permanently or temporarily, for example by screwing, jamming, etc. The Worktop 48 is used for a coiler 30 serving fitter as a storage area for tools and the like, but also as a storage area for abzulängende Well. For example, a vice or the like may be attached to the work surface 48 in order to clamp the material to be cut off, for example, to be cut to length with a saw. Finally, the work surface 48 or a regular spacing between the posts 32 may also be used as an orientation in cutting a length of reel 10, cable reels or the like, namely, if the posts 32 have a regular and known distance determined by the length of the axes 36 fifty centimeters, a hundred centimeters, a hundred and fifty centimeters or so.
