FILM COIL SUPPORT

DESCRIPTION OBJECT OF THE INVENTION

The present invention relates to a support for film reels, typically wrapping film, such as plastic film.

BACKGROUND OF THE INVENTION

Nowadays, plastic film reels are known that are widely used in packaging, from palletized merchandise to destination luggage to catch a flight.

The manual handling of these coils includes taking them by their ends and, placing them as parallel as possible to the object to be wrapped, applying the film by turning the reel with your hands.

To stiffen the coils, which are often of a certain width, elements arranged inside are known, such as the traditional cardboard or plastic pipe. In addition to this, there are known supports that comprise two tubular sectors with a tongue and groove in their ends for continuous connection, means to fit with the central recess of the coil (provided or not with a canute) to support the rotation of both, and speakers or widened areas extreme and open to the outside, arranged at the distal ends of the sectors (those that are more separated when coupled to each other) for introduction of the hand for handling the coil mounted on the support.

These supports facilitate the handling of the coils and have a better feel than the traditional cardboard poles, but they have the disadvantage that the speakers have edges that hurt the hand, leading to produce cuts, so in the end the handling does not manage to be everything how efficient it can be with the support of the invention.

DESCRIPTION OF THE INVENTION

The support for film reels of the invention is of the type comprising:

-Two tubular sectors with a tongue and groove in their ends for continuous connection, -mediums to fit with the central recess of the coil (whether or not provided with a canute) to support the rotation of both, and

-a horns arranged at the distal ends of the sectors for the introduction of the hand for handling the coil mounted on the support.

With this basic configuration, and in accordance with the invention, the horns comprise, at least, an outer perimeter extension of revolution around the axis of the support, of suitable width for flat hand support (not on edges), so that avoid support on sharp edges, avoiding injuries and improving handling.

But not only this, as an additional advantage has been found that, giving this extension convenient width so that it can contact the thumb of the hand, it can be used to regulate the braking of the coil rotation (around the areas of the hands configured by the other four fingers introduced in the speakers), which serves to give adequate tension to the film on the packed object with great comfort, increasing the speed of the packaging work and its accuracy.

DESCRIPTION OF A PRACTICAL EMBODIMENT OF THE INVENTION

The support (1) for film reels (2) of the invention (see figs. 1 to 3) is of the type comprising: - two tubular sectors (4, 5) with a tongue and groove (6) at their ends for continuous connection ,

-mediums to fit the central hole (20) of the coil (provided in this case with a pipe (21)) to support the rotation of both, and

-a horns (7) arranged at the distal ends of the sectors (4, 5) for insertion of the hand (8) for handling the coil (2) mounted on the support (1), where according to the invention, the horns (7) comprise, at least, an outer perimeter extension (70) of revolution around the axis (10) of the support (1), for flat support by hand.

In a very preferred variant of the invention shown in the figures, it is provided that the perimeter extension (70) has a width similar to that of the thumb (between 5 millimeters and 20 millimeters) in order to support the thumb (100) in the same and regulate the braking, configuring a kind of braking track for this finger.

In the preferred variant it is also preferred that the generatrix (71) (see fig. 6) of the perimeter extension (70) be straight, so that the increase in thumb pressure results in a braking increase as linear as possible. Likewise, it is preferred that the generatrix (71) of the perimeter extension (70) be parallel to the axis (10) of the support (1) for a flat support of the finger in the direction where the braking is most effective, that is, completely perpendicular to the axis of rotation (axis (10) of the support (1)).

As for the means to fit the central recess of the coil can be (see figs 2 and

4) :

- truncated conical sections (14) of increasing section towards the distal ends of the sectors (4,

5) provided therein, and / or

-services (15) projections provided in said sectors (4, 5).

In the example represented in the figures, both are combined.

Also indicate that the sectors (4, 5) are preferably materialized in plastic, due to the economy and ease of manufacture.

The invention has provided for the provision of additional means to facilitate the rotation of the coil with the least friction against the hand, with the exception of the thumb for braking. For this purpose (see figs. 5 and 6) it is provided that the horns (7) may comprise means for rotating attachment - around the shaft (10) of the support (1) - of a formally and dimensionally suitable grip knob (16) for grasping with the corresponding hand (8). In this way there is no friction with the hand, since the rotation of the coil (2) results in a sliding between the support (1) and these knobs (16). Said rotating fixing means most preferably comprise an annular wing (18) of revolution around the axis (10) of the support (1), projection of one of the elements to be joined (horn (7) or knob (16)) and a housing annular (19) complementary to the revolution around the axis (10) of the support (1) arranged in the other element to be joined; comprising a gap between annular wing (18) and annular housing (19) to allow mutual sliding. The annular wing (18) can be continuous (a continuous ring) or segmented (present discontinuities for saving material). In addition, it is preferred that the knob (16) be similar in shape to that of the horn (7) to overlap the inside thereof to allow the hand (100) to be inserted and to better hold the support (1) and therefore the coil (2) during driving. Said knobs (16) can be materialized in plastic for the same reasons as the rest of the support (1) already exposed.

Sufficiently described the nature of the invention, as well as the manner in which it is carried out in practice, it should be noted that the provisions indicated above and represented in the attached drawings are subject to modifications in detail as long as they do not alter the fundamental principle.
