DETAILED DESCRIPTION OF SOME PREFERRED EMBODIMENTS

[0040] In FIGS. 1 to 5 the first constructive form of an arched easy grip handle 1 according to the invention on a container 2 for loose or liquid materials, i.e. like a mason's bucket visible in the figures. The easy grip and arched handle is hinged on the sides 3 of the container 2 in opposite positions, diametrically opposed in the case of circular shapes such as the bucket shown. Close to at least one of the hinges 4 of the arched handle, a positioning means, shown here as a positioning arm 5 rotating with the same easy grip and arched handle, is fitted to the handle pin. At the end 6 of the positioning arm 5 a permanent magnet 7 is connected which, with the rotation of the arched handle and positioning arm assembly, makes a rotation, so as to reach a position opposite to the reclined position of the easy grip and arched handle on the side; correspondingly in the position in which the arched handle is almost vertical with respect to the container 2, a ferromagnetic element 8 is housed in the side 3 of the container. The magnetic attraction between the permanent magnet 7 and the ferromagnetic element 8 keeps the arched handle 1 in a fixed position, whether it is an almost vertical position, FIG. 1, or a reclined position, FIG. 2. The ferromagnetic element 8 is contained in a specific seat made in the construction of the side 3 of the container.

[0041] The mason's bucket depicted as a portable container on which the easy grip arched handle is applied is generally made of a plastic material, therefore the ferromagnetic elements 8 are inserted in raised seats 9 projecting on the side 3 of the portable container.

[0042] A second constructive form of an easy grip handle mounted on a portable container is shown in FIGS. 6 to 9, in which like parts have like numerals with respect to the preceding Figures. The easy grip and arched handle 1 is connected and rotates in the hinges 3 of the portable container 2 together with a positioning means made here with a positioning arm 10 made of ferromagnetic material. The end 11 of the positioning arm 10 is subject to the attraction of a permanent magnet 12 which, when the rotation of the arched handle assembly and positioning arm, determines the proximity to a respective permanent magnet 12, in a position opposite to the reclined position of the easy grip and arched handle on the side or, correspondingly, in the position in which the arched handle is almost vertical with respect to the container 2. A permanent magnet 12 is housed in each raised seat 9 in the side 3 of the container. The magnetic attraction between the permanent magnet 12 and the end 11 of the ferromagnetic positioning arm 10, when facing the magnet, maintains the easy grip and arched handle 1 in a fixed position, whether it is in an almost vertical position or also in a position. reclined on one side or on the opposite side at the position of the raised seats 9 in the side 3 of the portable container 2.

[0043] A third constructive form of an easy grip handle mounted on a portable container is shown in FIGS. 10 to 17, in which like parts have like numerals with respect to the preceding Figures. The easy grip and arched handle 1 is connected and rotates in the hinges 16 of the sides 17 of the portable container 2 together with a positioning means made here with a rotating flange 18 together with an end 19 of the easy grip and arched handle 1. The rotating flange 18 faces against a radial surface 20 with respect to the hinge 16 on which magnetic elements 21 are positioned inside a circle corresponding to the outer diameter of the rotating flange; said magnetic elements consist of separate permanent magnets or magnetized sectors of a single toroidal element. In the rotating flange 16 are housed, in the surface facing the radial surface 20, ferromagnetic elements 22 in a number equal to the magnetic elements 21 and identically equidistant in the arc of rotation possible for the easy grip and arched handle 1, plus two further ferromagnetic elements 23 of correspondingly equidistant ends. The connection between the rotating flange 18 and the end 19 of the easy grip and arched handle 1 can take place in the most convenient ways based on the material of the rotating flange 18, by interference fitting, fitting with a shaped end or even with a roll pin 24, as shown, in the appropriate matching holes on said end 19 and on the hub of the rotating flange 18.

[0044] As described, the ferromagnetic elements 22 are subject to the attraction of the magnetic elements 21 when the rotation of the easy grip and arched handle and rotating flange assembly determines the correspondence of a respective magnetic element 21, so that the handle maintains the reclined position on one side or, correspondingly, the position in which the easy grip and arched handle is almost vertical with respect to the container 2; the handle itself remains in the corresponding position due to the attraction of two or more magnetic elements on the corresponding two or more facing ferromagnetic elements. The positioning angle D, on the right, or S, on the left, with respect to the central average vertical position of the easy grip handle 1, can be the same or also different depending on the practicality of the grip required by the user of the container 2 on which the easy grip handle is made.

[0045] The use of the portable container on which an easy grip handle is made is obtained by simply moving the easy grip handle 1, rotating it within the respective hinges 4 or 16, allowing the handle itself to reach the position desired by the user, whether it is reclined on one or on the other side or almost vertical with respect to the container 2 itself. The action of attraction between the magnetic element 7, located at the end 6 of the positioning arm 5, and one of the ferromagnetic elements 8, stably positions the same handle in the first constructive form. In the same way, the second constructive form operates with the attraction between the end 11 of the positioning arm 10, which is ferromagnetic, and one of the magnetic elements 12, firmly housed in the respective raised seats 9, present in the side 3 of the container 2.

[0046] With the third constructive form, the position of the magnetic elements and of the ferromagnetic elements facing the radial surface 20 can be obtained in a different way from the one shown, that is by inserting not only three magnetic elements 21 in the seats, inserting a complete number of them corresponding to the number of ferromagnetic elements that must be attracted. In this way the applied attraction force is high, being realized on each correspondence between the magnetic element and the facing ferromagnetic element, and, therefore, the size of the magnetic elements can be reduced in proportion to the forces involved, to the mass of the easy grip handle and to the grip and displacement force, which the user applies to handle the easy grip handle itself when the container is empty, therefore not subject to the mass of its content.

[0047] The advantages in the use of a portable container in which an easy grip handle 1 is made according to any one of the described constructive forms are manifested in the practical use to which the container 2 is put. The user releases at any time the handle of the container and finds it in the same position in which it left it. Therefore, the position of the handle close to the vertical direction is certainly the most advantageous, being made stable and in a practical and simple way already during the construction of the container 2 itself.

[0048] Obviously, a person skilled in the art, in order to satisfy specific and contingent requirements, may make numerous modifications to a portable container in which an easy grip handle is made, as previously described, all however contained within the scope of protection of the present invention as defined by the following claims. Obviously, although less conveniently, the magnetic elements 21 and the ferromagnetic elements 22 in the third constructive form can be inverted in their position indifferently, i.e. housed in the rotating flange 18 or in the facing radial surface 20. Finally, although less conveniently, the magnetic elements can be present both in the rotating flange and in the facing radial surface, but organized with the facing polarity allowing the attraction and not the reciprocal repulsion in defining the foreseen positions of the easy grip handle in the container 2; in fact a permanent magnet is made of ferromagnetic material and has attraction or repulsion with other permanent magnets based on polarity. Furthermore, the container may have a squared shape and a positioning arm or flange operating with a hinge located outside the sides of the container 2.
