Description:
WINDING DEVICE FOR BELTS AND ROPES

The present invention refers to a winding device for belts and ropes, in particular a manual winding device, usable to wind belts and ropes used for binding and fastening loads having every shape and size on flatbeds of transport means, such as trucks, railway wagons, ship loading planes, or under any situation in which it is necessary to fasten an object to a plane and make it stable.

More in particular, the winding device for belts and ropes of the invention can be used to wind belts and ropes at the end of their transport, when they are wound to be stored for their following use.

It is known in the art to use belts, which are laid on a load to be fastened after having been hooked on one side and subjected to traction by means of a pawl or ratchet to tighten the load; in order to have a comfortable use, such belts are wound on their flat part to obtain a roll of belt to be easily unwound and/or laid onto the load, leaving it above the load, allowing it to easily reach the opposite side to its fastening point.

For such use, it is necessary that the belt is supplied and kept by the users in a package as compact and well aligned wound.

These known belts and ropes have the problem that, when it is necessary to perform numerous binding and ordering operations for them, it is scarcely practical to re-wind the belt, especially in case of transporters who have numerous belts to collect and re-wind many times a day, with a great waste of time, above all in case of negative atmospheric conditions, for example when there is rain or snow, which complicate and increase the discomfort in re-winding the belts in well composed rolls .

Winding devices for belts and ropes are known, equipped with mechanisms, or with motors, which have big overall sizes and must be fastened, for example to a vehicle, to be used, thereby resulting complex and scarcely practical to use.

With reference to the Figures, preferred embodiments of the winding device for belts and ropes according to the present invention are shown and described.

The winding device 10 for belts and ropes of the invention comprises a first element 11, a second element 12 rotatably and removably connected to the first element 11 and comprising fastening means 15 of a belt 14 or rope, catching means 18 connected to the second element 12 to allow a user to manually rotate the second element 12 and the fastening means to wind the belt or rope 14 blocked by the fastening means 15. In particular, the first element 11 and the second element 12 are removably connected to allow extracting the belt or rope 14 when it is wound, after the first element 11 and the second element 12 have been separated.

Preferably, the second element 12 comprises a pin 16 rotatably and removably connected to the first element 11, on which pin 16 the fastening means 15 are made; for example, the pin 16 comprises a seat 21 rotatably and removably connectable to a fastening pin 22 made on the first element 11; for example, the seat 21 comprises an annular element which can be inserted into a corresponding seat of the fastening pin 22, in order to block the translation of the second element 12 and of the pin 16 with respect to the first element 11, however leaving them free of rotating .

In a preferred way, the fastening means 15 are composed of a notch 15, preferably longitudinal and through, made on the pin 16, within which an end of the belt or rope 14 can be inserted; preferably, the first element 11 and the second element 12 have a substantially plane shape, more preferably a disk, to allow placing the device 10 occupying a very small space, storing it together with the wound belts 14, leaving the last belt 14 wound thereon .

In a preferred way, the winding device 10 for belts and ropes of the invention comprises second catching means 19 connected to the first element 11 to allow the user a firm grip of the winding device

10 for belts and ropes 14, in particular of the first element 11, when he manually rotates the second element 12 with respect to the first element

11 to wind the belt or the rope 14; for example the catching means 18, 19 are knobs.

In a first embodiment of the winding device 10 for belts and ropes 14 of the invention, shown in Figure 4, the pin 16 comprises a part 24 being shaped as a cone and/or has an end 25 with reduced diameter to keep a distance between the belt or the rope 14 and the pin 16, when it is wound thereon, in order to decrease the friction between the wound belt or rope 14 and the pin 16, allowing an easy removal of the belt 14 from the device 10 ponce it has been wound, and the first element 11 has been separated from the second element 12.

In a preferred way, the pin 16 is formed of two hollow semi-cylindrical shells 27, for example made of moulded iron, which, when flanked, form the pin, leaving between them the notch 15 for inserting the edge of the belt 14 and the following winding .

Preferably, the two shells 27 which form the pin 16 have a second enlarged end 26 adapted to be engaged in the edge of a ring-nut 28 which is afterwards fastened, for example screwed onto the second element 12 to fasten the pin 16 thereto.

In a second embodiment of the winding device

10 for belts and ropes 14 of the invention shown in Figures 5a and 5b, the pin 16 comprises a housing 29 made at least in a shell 27 in which a projecting element 31, for example a rod or a quarry, is inserted, rotatable on its axis and having a first external surface 32 adapted to go out of the housing 29 when the projecting element 31 is rotated in a first position, thereby allowing to increase the diameter of the pin 16, and having a second external surface 33, for example plane, which remains inside the housing 29 when the projecting element 31 is rotated in a second position, to enable the belt 14 to go out of the pin 16 when it is wound, loosening it and thereby increasing the diameter of the pin 16 on which it has been wound.

For example, the rotation of the projecting element 31 is performed through a lever 34 connected thereto through gears 35 and located on the second element 12.

At an end of the projecting element 31, next to the first element 11, a projection 36 is obtained, preferably shaped as a disk, adapted to be inserted into a continuous circular seat obtained in the first element 11, to connect the first element 11 and the second rotatable element 12, preventing the disengagement of the pin 16 during the winding operation.

With the rotation of the projecting element 31, also the projection 36 enters inside the housing 29 when the projecting element 31 is rotated in the second position, allowing to separate the first element 11 and the second rotatable element 12.

Advantageously, this projection 36 does not prevent the rotation of the second element 12 and does not create additional frictions, makes the device 10 stable during the first winding turns and makes it solid.

In a third embodiment of the winding device 10 for belts and ropes 14 of the invention shown in Figure 6, the pin 16 comprises two housings 29, each one made as a shell 27, in each of which a projecting element 31, as those previously described, is inserted.

In a fourth embodiment of the winding device 10 for belts and ropes 14 of the invention shown in Figures 7a and 7b, the pin 16 is formed of two filled semi-cylindrical shells 27a, for example made of plastics or aluminium or steel, hinged in a hinge 37 at their second end 26 and made in order to leave a space between them to form the notch 15, when are closed to compose the pin 16.

The hinge 37 is perpendicular to the axis of the pin 16 formed of the shells 27a which are closed on the fastening pin 22 made in the first element 11, through an elastic element 38, for example a helical spring, in order to exert a force adapted to keep the shells 27a closed inside the ring-nut 28 and allow the rotation of the second element 12 and of the pin 16 with respect to the first element 11.

Upon separating the first element 11 from the second element 12, the hinge 37 allows the two shells 27 to approach, decreasing the tension at the centre of the wound belt 14 wound and enabling their withdrawal from the pin 16.

In a fifth embodiment of the winding device 10 for belts and ropes 14 of the invention shown in Figures 8a, 8b and 8c, the pin 16 comprises a housing 29, preferably longitudinal, made therein, and the fastening means 15 of the belt 14 comprise a blocking element 41 of the belt 14, inserted rotatable into the housing 29 and projecting therefrom to block an edge of the belt 14, allowing its winding on the pin 16.

The winding device 10 for belts and ropes 14 according to the fifth embodiment of the invention further comprises activating means 44 adapted to activate the blocking element 41 of the belt 14.

Preferably, the fastening means 15 of the belt 14 comprise a shaft 42 inserted rotatable into the housing 29, connected to the blocking element 41 of the belt 14, composed for example of a blade 41 projecting from the housing 29 to block an edge of the belt 14 between the blocking element 41 itself and the edge of the notch 15.

In a preferred way, the activating means 44 comprise a push-button 46 adapted to push a lever 48 connected to the shaft 42, for example keyed thereto, to rotate it, thereby rotating the shaft 42 around its axis, together with the blade 41 connected thereto; in a preferred way, the activating means 44 further comprise an elastic element 38, for example a torsion spring, to keep the blade 41 in contact with the belt 14, which is thereby kept gripped against the edge of the notch 15.

Advantageously, the winding device 10 for belts and ropes according to the fifth embodiment of the invention allows using a smaller winding diameter of the belt, capturing and fastening an edge with a small length to enable the disconnection and unloading step of the roll of belt wound onto the pin.

Advantageously, by pressing the push-button 46, the blade 41 is rotated, freeing the edge of the belt 14; this operation is performed when winding: by pressing the push-button 46, the blade 41 opens, creating the space for inserting the terminal edge of the belt 14 between the blade 41 itself and the edge of the notch 15; by releasing the push-button 46, the spring 38 keeps the blade 41 in contact with the belt 14, keeping it gripped against the edge of the notch 15, allowing to start winding the belt 14.

Advantageously, the winding device 10 for belts and ropes of the invention allows an easy use even under negative weather conditions, for example with wet belts or ropes, avoiding to wet hands or gloves of a user and allowing to wring the belt when winding it, expelling water therefrom.

Advantageously, the winding device for belts and ropes of the invention allows reducing the necessary time to re-order and place the belts or ropes, further preventing their deterioration due to an incorrect winding, and further allows placing the device 10 occupying a reduced space, storing it together with the wound belts, leaving the last belt wound thereon.

Moreover, its simple operation with an almost complete absence of maintenance makes it suitable to be used also in scarcely clean environments, without being it necessary to particularly take care of it when using or when storing it.
