Detailed Description

With reference to the accompanying drawings, the numeral 1 designates in its entirety an accessory for a self-propelled machine 10, comprising a device 2 according to the invention and a tool 3 carried by the device.

More specifically, in the example shown, the apparatus 2 is an improved fork holder designed for use with a telescopic boom forklift 10, and the tool is a fork for lifting a load, however, the inventive concept of the present invention may also be incorporated in different apparatuses.

The proposed apparatus 2 comprises a supporting frame 21, 22, 23, preferably a quadrangular shaped frame, designed to be attached at the rear, for example by means of a rear tubular element, referenced 24 in the figures, to a device 101, which device 101 is intended to be connected to an operating arm 102 of the machine 10.

Furthermore, the device 2 is designed to be coupled to the tool 3 at the front and to support the tool 3.

It should be noted that the expression "at the front" with reference to the apparatus 2 refers to the side (or face) opposite to the machine 10 and the arm 102, while the expression "at the rear" refers to the opposite side.

According to an important aspect of the invention, the frame of the apparatus 2 comprises two lateral uprights 21, 22 (e.g. two plates) joined at the top by a transverse plate 23 instead of the tubular elements of the prior art.

More specifically, the transverse plate member 23 is inclined downwardly in the front direction, preferably forming a downward acute angle (lower angle) with the longitudinal axis of the extension of the uprights 21, 22.

In more detail, if the tool 3 is a fork, the plate 23, which serves as an upper crosspiece, lies in a plane which may define an angle of between 20 and 30 degrees, and preferably between 22 and 24 degrees, with the plane on which the tines 31, 32 lie; even more preferably, the angle is substantially equal to 23 degrees.

As mentioned above and shown in fig. 4 and 5, uprights 21, 22 may be two plates parallel to each other and provided with respective slots 211, 221 for simultaneously receiving elongated support elements 33 of tool 3.

If the tool 3 is a fork, the support element 33 may be a tubular element, preferably circular, on which the tines 31, 32 are mounted, as explained in the description of the prior art, which tines may be slidably associated with the support element.

Furthermore, there may be a central plate 25 connected to the transverse plates 23 and perpendicular thereto, which is likewise equipped with slots 251 for receiving the support elements of the tool 3.

Preferably, the invention comprises two clamps (jaw) 41, 42 removably coupled to the support element, for example by using thumb screws, for locking the tool 3 to the uprights 21, 22 of the device 2.

In practice, the cylindrical ends of the fork tines 31, 32, inserted on the supporting pin 33, are closed in a sandwich-like manner between the clamps 41, 42 and the uprights 21, 22, which constitute the two side walls; alternatively, the cylindrical end can be closed between the two clamps in any position along the pin 33.

The operation of the present invention is explained below with reference to the drawings, whereby a comparison can be made between the prior art and the present invention.

In fig. 8, the numbers N1 'and N2' refer to two invisible spacings for an operator in the cab in the case of use of the device 2 according to the invention.

As is immediately clear from the comparison between fig. 3 and 8, the invisible spacing N1 'and N2' of the proposed device 2, in particular at or near the top ends of the tines 31, 32 of the fork, is significantly reduced compared to the invisible spacing of prior art equipment, which has significant advantages in terms of safety and ease of use.

In fact, thanks to the use of the upper crosspiece defined by the transverse plate 23, when the operator has brought the accessory close to the load, the point of view of the operator looking at the load to be forked is far less obstructed than that of conventional devices.

In this way it is avoided that the operator has to perform, before picking up the load, the inconvenient and inefficient operations mentioned during the discussion of the prior art.

Further, by eliminating the tubular crosspiece and by applying the configuration according to the invention, the tool 3 located on the device 2 can also have a greater degree of inclination, thus obtaining a smaller overall size of the accessory 1 during road transport.

In fact, as can be seen by comparing fig. 6 and 7, it is clear that the invention allows the prongs 3 to be inclined with a front angle between them and the device 2 that is significantly greater than the inclination angle of the prior art.

It should also be noted that the fixing operation is safer since the centre of gravity of the fork 3 according to the invention is positioned in a position in which it tends to keep them in the inclined configuration.

In order to keep the tines 31, 32 in the inclined position, a suitable bracket is provided which replaces the prior art chain; when not in use, these brackets can be simply anchored to the rear of the apparatus 2, which has a clear benefit in terms of operator convenience.

It should also be noted that by locking the position of the tines 31, 32 with respect to the tubular element for supporting the fork with clamps 41, 42 (which are also manually removable, in particular if thumb screws are used to clamp them), it is easier to assemble and disassemble, but above all it allows the device 2 to be equipped with tools even of different sizes and better adjust the relative position in which they are to be applied to the device 2.

Finally, according to an advantageous preferred feature of the invention, the apparatus 2 is equipped with a removable load support grid 5, for example by means of bolts joining it to the transverse plates 23, unlike the prior art which uses grids welded to the upper tubular crosspiece.

In this way, giving priority to heavy loads or visibility firmly on the grid, it is possible not only to choose when the grid is used but also to easily replace the grid 5 in case of damage.
