## Abstract

A telescopic reel includes a telescopic supporting frame and a central module including at least one bracket constrained to the supporting frame and connectable to a bearing and guide through a fastener. The bearing and guide is adapted to bear and guide, during its rotary motion, at least one transversal intersection element of the reel. The bearing and guide is positioned on the at least one intersection element at a first distance from a longitudinal central shaft of the reel, the first distance being greater than or equal to a second distance between the central shaft and a crosspiece of the reel.

## Claims

### Claim 1

A telescopic reel comprising:
a supporting frame having a length extending between a first end and an opposing second end of the reel, said support frame being telescopic so that said length is adjustable by one portion of the support frame being slidable within another portion of the support frame; and
a central module disposed centrally along said support frame, comprising:
at least one bracket constrained to said supporting frame;
at least one transversal intersection element being rotatable relative to said at least one bracket; and
bearing and guiding means through for bearing and guiding said at least one transversal intersection element during its rotary motion relative to said at least one bracket, said bearing and guide means be connected to said bracket by fastening means;
a longitudinal central shaft extending between said first end and said opposing second end of the reel and extending laterally and centrally from said at least one transversal intersection element;
said bearing and guiding means being positioned on said at least one intersection element at a first radial distance from said longitudinal central shaft; and
a cross piece extending between said first end and said opposing second end of the reel and extending lateral to said at least one transversal intersection element at a second radial distance from said longitudinal central shaft, said first radial distance being greater than or equal to said second radial distance.

### Claim 2 (depends on 1)

The telescopic reel according to claim 1, wherein said at least one intersection element comprises drive means capable of receiving motion through motion transmission means connected thereto; said motion transmission means being connectable to a motor and acting upon said drive means in proximity to said first radial distance.

### Claim 3 (depends on 1)

The telescopic reel according to claim 1, wherein said bearing and guiding means are connected to a motor and allow the rotation of said at least one intersection element.

### Claim 4 (depends on 2)

The telescopic reel according to claim 2, wherein said drive means comprise at least one element selected from the group including: a toothed wheel, a disk, a gear, a pulley, a thrust block.

### Claim 5 (depends on 2)

The telescopic reel according to claim 2, wherein said motion transmission means comprise at least one element selected from the group including: a chain, a rubber belt, a gear.

### Claim 6 (depends on 1)

The telescopic reel according to claim 1, wherein said bearing and guiding means comprise bearings.

### Claim 7 (depends on 1)

The telescopic reel according to claim 1, wherein said fastening means comprise bolts.

### Claim 8 (depends on 2)

The telescopic reel according to claim 2, wherein said at least one transversal intersection elements comprises said drive means, sliding flanges and fixed flanges.

### Claim 9 (depends on 1)

The telescopic reel according to claim 1, wherein said longitudinal central shaft is telescopic so that a length of said central shaft is adjustable by one portion of said central shaft being slidable within another portion of said central shaft.

### Claim 10 (depends on 1)

The telescopic reel according to claim 1, wherein said bearing and guiding means are configured so as to be retained at a constant radius from said central shaft as said transversal intersection element is rotated relative to said at least one bracket.
