DETAILED DESCRIPTION OF THE INVENTION

(6) In view of the above-said and with reference to the numbering adopted in the figures, FIGS. 1 to 3 depict the preferred embodiments of the lamp ring, which is the object of the invention,

(7) FIG. 1 represents an elevation view of the device for connecting parts of a crate, object of the invention. The connecting device is composed of two parts coupleable with each other, a female sheet (1) and a male sheet (2), which may interchangeably act as base, lid or side walls of a crate in different embodiments of the invention. Said female sheets (1) and male sheets (2) may adopt different geometries in different embodiments of the invention, a preferred embodiment being that wherein a rectangular prismatic shape is adopted, its thickness being defined by a peripheral surface (5). Said thickness defined by a peripheral surface (5) may change depending on the consistency the definitive crate is meant to have.

(8) In FIG. 3, the geometry of a female sheet (1) may be better observed, which in the proximity of its peripheral surface (5) comprises at least one slot (4). Said slot (4) creates a through hole in said female sheet (1), the hole being the prismatic-shaped slot (4), for the coupling with a tab (6) belonging to the male sheet (2), Said sheet (2) comprises a second stop element (11) in its lower horizontal surface, whereon a guiding surface (9) of the tab (6) is supported for the appropriate coupling of the sheets.

(9) In FIGS. 1 and 2, the geometry of two embodiments of the male sheet (2) can be better observed. In the peripheral surface (5), the tab (6) extends for it to be coupled in the slot (4) of the female sheet (1). Said tab (6) comprises in its upper part closest to the peripheral surface (5) a first stop element (10) of rectangular shape, which is coupled in the upper surface of the slot (4) of the female sheet (1). An upper surface (7) of the tab (6) extends upwards following the first stop (10), said upper surface (7) describes an upward chamfer, a horizontal surface and another downward chamfer. Subsequently, a front surface (8) of the same width of the peripheral surface (5) of the male sheet (2) and of shorter length than the length of the slot (4) of the female sheet (1) is extended. Finally, in this embodiment, the lowest part of the front surface (8) is completed with a round-shaped lower surface (14). Said interior lower surface (14) extends up to a guiding surface (9), which is inclined ranging between 0 and 30 until it fits with the second stop element (11) of the female sheet (1).

(10) In an embodiment of the invention the guiding surface (9) starts from the lower surface (14) with an inclination ranging between 31 and 60, as can be observed in FIG. 2. In this embodiment of the invention, the lower surface (14) comprises a circular chamfer.

(11) The invention is characterized by a coupling between the male sheet (2) and the female sheet (1) by means of two simple-path movement directions, without changes in direction. In a first movement (12) perpendicular to the external side (3) of the female sheet (1), the slot (4) of the female sheet (1) and the tab (6) of the male sheet (2) are placed facing each other. Said elements are placed in such a way that the first stop element (10) faces the upper surface (7) of the tab (6). Then, the first movement (12) begins, in perpendicular direction to the external side (3) of the female sheet (1) and oriented towards the peripheral surface (5) of the male sheet (2), until said peripheral surface (5) is faced and in contact with the female sheet (1). In this manner, the first stop element (10) of the male sheet (2) is faced at certain distance from the upper surface of the slot (4) of the female sheet (1).

(12) In a second movement (13) in parallel direction to the external side (3) of the female sheet (1), and oriented towards the first stop element (10) and the second stop element (11), the upper horizontal surface of the slot (4) is made to face and coincide with the first stop element (10) of the male sheet (2). Likewise, the lower surface of the guiding surface (9) is made to face and coincide with the second stop element (11) of the female sheet (1), This second movement (13) can be applied by means of a mechanical action in an embodiment of the invention. In another embodiment of the invention, this second movement (13) is applied by means of a guiding action resulting from the geometry of the tab (6). Thus, the tab (6) is perfectly fit in the slot (4), as it may be observed in FIG. 3.

(13) The invention is characterized in that said connection may be carried out between two parts of a crate, either a lid or its side sheets or its base.

(14) The present invention is not limited by the embodiments disclosed herein, Other embodiments can be made by those skilled in the art following the present description in consequence, the scope of the invention is defined by the following claims.
