The support body 4 is further provided with an oscillating control lever 12 for a coupling member 13 of the support body 4 to the guide 3.

The oscillation plane of the lever 12 is parallel to the flat base of the support body 4 and, consequently, to the bottom of the drawer 2.

The hooking member 13 is movable between a hooking position of the drawer 2 to the removable part 14 of the guide 3, position in which it engages in a seat 15 provided in the removable part 14 of the guide 3, and a position of disengagement in which the seat is disengaged 15.

The lever 12 advantageously shows a first surface area 16 for the manual grip in which the user can exert, with his fingers of one hand, a traction that determines a first activation force F1 of the lever 12, and a second zone 17 of surface, for the manual grip, in which the user can exert, with his fingers of one hand, a traction that determines a second force F2 of activation of the lever 12.

12 to the second activation force F2 with a direction substantially parallel to the longitudinal direction of the guide 3.

The first surface area 16 and the second surface area 17 are different and are provided on the same arm of the lever 12 and, in particular, on the converging sides of an angled part 18 of the lever 12.

The part of the lever 12 in which the first surface area 16 and the second surface area 17 are placed is the opposite part of the guide 3 with respect to the swinging support point of the lever 12.

Next, reference will be made in more detail to the embodiment of Figures 1 and 2. In this case, the swing support point of the lever 12 is constituted by a hinge shaft with which the lever 12 is hinged to the body 4 support.

The lever 12 may oscillate in the direction that the coupling member 13 leads to the disengagement position in contrast to an elastic automatic adjustment element 25 of the engagement member 13 in the engagement position.

The elastic element 25 comprises a flexible plate spring showing a firmly constrained end on the lever 12 and an end resting against a wall of the body 4. The plate spring is operative in a recess 26 of the body 4 and protrudes from the second surface area 17 in a longitudinal direction towards the coupling member 13 and subsequently thereto.

The first surface area 16 extends from the side of the second surface area 17 facing the part of the support body 4 with which it rests laterally in the drawer 2.

In particular, the first surface area 16 extends on the lever 12 in the direction of the front part 5 of the drawer 2, on a side opposite to the hitch member 13 with respect to the hinge axis 19 of the lever 12, while the second surface area 17 extends on the lever 12 on an opposite side to the longitudinal guide 3 with respect to the hinge axis 19 of the lever 12.

The coupling member 13 is made in one piece with the lever 12.

In the situation where the lever 12 is easily accessible only on a side part of the drawer 2, the user with his fingers exerts a traction, pressing on the first surface area 16, in a manner that generates the force F1 of activation with a direction perpendicular to the guide 3, which is suitable to make the lever 12 oscillate around the axis 19 until the engagement member 13 is brought from the engagement position to the disengaging position.

On the other hand, in the situation in which the lever 12 is easily accessible only from the front of the drawer 2, the user, with the fingers of his hand, exerts a traction by pressing on the second surface area 17, in such a way which generates the activation force F2 with a direction parallel to the guide 3, which is again suitable to make the lever 12 oscillate around the axis 19 until the engagement member 13 is brought from the engagement position to the disengaging position.

Next, reference will be made in more detail to the embodiment of Figures 3 and 4. In this case, the lever 12, the coupling member 13 and the support body 4 are made in a single piece showing at least one part which yields elastically suitable to allow a reversible oscillation of the lever 12 from the engagement position to the disengagement position of the engagement member 13.

The elastically yielding part, which defines a swinging support point of the lever 12, comprises a first flange 21 and at least a second flange 22 for connecting the lever 12 to the support body 4.

In the situation in which the lever 12 is easily accessible only from a side face of the drawer 2, the user, with the fingers of his hand, exerts a traction by pressing on the first surface area 16, in a manner that generates the activation force F1 with a direction perpendicular to the guide 3, which is suitable for elastically deforming the tabs 21 and 22 which, as they flex, cause the lever 12 to oscillate around the support point defined in this way until the hitch member 13 from the hitch position to the disengagement position. When the grip is released, the tabs 21 and 22 recover their elastic deformation and the lever 12 automatically returns to the engagement position of the engagement member 13.

On the other hand, in the situation in which the lever 12 is easily accessible only from the front of the drawer 2, the user, with the fingers of his hand, exerts a traction by pressing on the second surface area 17, in such a way which generates the activation force F2 with a direction parallel to the guide 3, which is again suitable for elastically deforming the flanges 21 and 22 which, by bending, cause the lever 12 to oscillate around the support point defined in this way until bring the hitch member 13 from the hitch position to the disengagement position.

Next, reference is made in more detail to the embodiment of Figure 5.

In this case, the swing support point of the lever 12 is constituted by a hinge shaft 19 with which the lever 12 is hinged to the support body 4.

In this case, the hooking member 13 comprises a slide 20 slidably supported parallel to the base of the support body 4 and perpendicular to the longitudinal direction of the guide 3.

The cursor 20 shows a front projection 23 for engaging the guide 3, parallel side guide surfaces 24, 26 coupled along a straight guide 27 formed in the support body 4, and a rear wall 28, which engages operatively with the end of the arm 30 of the lever 12 opposite the end in which the first surface area 16 and the second surface area 17 are present.

The first surface area 16 extends on the lever 12 in the direction of the front part 5 of the drawer 2, on a side opposite the cursor 20 with respect to the hinge axis 19 of the lever 12, while the second zone 17 of surface extends on the lever 12 on a side opposite the horizontal guide 3 with respect to the hinge axis of the lever 12.

The lever 12 may oscillate in the direction that the engagement member 13 brings to the disengagement position in contrast to an elastic element 25 for automatic adjustment to the engagement position.

The elastic element 25 comprises a flexible plate spring that shows an end firmly constrained to the cursor 20 and which is interposed between the cursor 20 and the lower part 29 of the guide 27.

In the situation in which the lever 12 is easily accessible only from a side part of the drawer 2, the user with the fingers of his hand exerts a traction by pressing on the first surface area 16, in a way that generates the force F1 of activation with a direction perpendicular to the guide 3, which is suitable to make the lever 12 oscillate around the axis 19. By effect of the oscillation, the arm 30 of the lever 12 attracts the cursor 20 in translation, cursor 20 which is leads to the disengagement position in which the elastic element 25 is loaded by elastic deformation against the lower part 29 of the guide 27. When the grip is released, the elastic element recovers the deformation and automatically returns the cursor 20 to the engagement position .

On the other hand, the situation in which the lever 12 is easily accessible only from the front of the drawer 2, the user, with the fingers of his hand, exerts a traction by pressing on the second surface area 17, in such a way which generates the activation force F2 with a direction parallel to the guide 3, which is again suitable to make the lever 12 oscillate around the axis 19 until the release is obtained as described hereinbefore.

Therefore, the present invention provides a hitching device that is especially easy both for unhooking the drawer from a front part, and for unhooking it from the sides thereof, according to specific needs.
