DETAILED DESCRIPTION

[0053] With reference to FIG. 1, number 30 indicates overall a cage for pets, in particular rodents, that is made by joining four vertical mesh walls and a horizontal mesh wall, in which each of the walls is obtained by fixing through welding in the crossing points a plurality of parallel rods to other parallel rods arranged at right angles with respect to the other previously mentioned rods.

[0054] The components used to make the cage comprise a vertical mesh wall 31 placed on the front side and another corresponding wall 32 placed on the rear side, two side mesh walls 33 and 34, and a horizontal upper metal mesh wall 35 that acts as a roof.

[0055] The four vertical walls are located inside a base basin 36 generally made of plastic material adapted to contain possible inert grit or other material for collecting droppings.

[0056] According to an embodiment, the mesh walls 31, 32, 33, 34 and the upper wall 35 can be mutually joined and retained in position by coupling elements that enable the angular sectors of the various mutually approached mesh walls to be joined.

[0057] The main coupling elements according to an embodiment are those indicated by 37 and 38 in FIGS. 1-4, and are made of thermoplastic material, i.e., by hot injection of melted plastics into a mold, and permit joining between the front and upper corners of the two side walls 33 and 34 with the upper front corners of the front wall 31 and simultaneously with the front corners of the mesh wall 35 that constitutes the roof of the cage.

[0058] According to the embodiment shown in FIGS. 1-4, and more in detail in FIGS. 5A and 5B, the coupling elements 37 and 38 are specular and symmetrical to one another and, as visible in yet greater detail in FIGS. 12-12F, the coupling element 37 but similarly also the respective element 38 located on the opposite corner, consists of a plastic angle piece 39 associated with a pawl 40 that is coupled with the upper front corner of the right and left side to retain reciprocally the front upper corners of the side mesh walls 33 and 34, of the front wall 31 and upper wall 35 that acts as a roof.

[0059] More precisely the angle piece 39 of the coupling element 37 and of the specular element 38 thereof, according to the embodiment shown in FIGS. 12-12F, comprises a body 41 having a substantially vertical structure adapted to be inserted and fixed on the upper and front angular corner of the side walls 33 and 34 and thus the body 41 is provided with an inner housing 42, consisting of a vertical angular slit having a conformation such as to comprise perfectly the angular corner of the wall 33, as visible in FIGS. 14-14C.

[0060] Further, as shown in FIG. 12C, the inner face of the body 41 facing said pawl 40 is provided with a tooth 43 facing an elastic tongue 44, in which said tooth 43 and tongue 44 form a seat with a vertical axis in which the most external vertical rod 31′ of the front wall 31 is temporarily housed and fixed, as shown in FIG. 14C.

[0061] According to the embodiment shown in FIGS. 12-12F, and in particular in FIG. 12B, the pawl 40 is provided with a handle facing upwards and with a rotation shaft with a vertical axis that protrudes from the angle piece 39 to terminate with a coupling element 45 with an arrangement that is orthogonal to the shaft but with an operating seat with an axis that is parallel to the shaft that intercepts one of the vertical rods of the front mesh wall 31, in particular the first, indicated by 31′, as shown in FIG. 14C.

[0062] The coupling element 45 is subject to an angular rotation on a vertical axis given by the handle of the pawl 40 so as to adopt two positions arranged at 90° from one another: a release position retracted to the inside of the cage with an arrangement substantially parallel to the front wall 31 and a position constrained on the second rod 31″ of the front wall 31, as shown in FIG. 14C, i.e. a coupling arrangement ejected outside.

[0063] Further, according to the embodiment shown in FIG. 12B, the handle of the pawl is spaced apart vertically from the horizontal portion of the angle piece 39, so that when the pawl is in a closed position it forms seats 46, 47 in which two more external horizontal rods are retained of the upper wall (35) that acts as a roof of the cage.

[0064] In fact, the handle of the pawl has a substantially prismatic rectangular shape that below the two elongated ends forms two equal and opposite undercuts so that in the open position it can enter between the two outer rods of the upper walls forming the roof and after rotation thereof by 90° locks the same two outer rods, retaining the roof in the closed position.

[0065] According to a further embodiment shown in FIGS. 13-13F, the rotatable handle of the pawl 40 is replaced by a sliding selector 48 associated with a coupling element 49 similar to the mentioned coupling element 45 and having the same function. In this case, the sliding selector 48, instead of rotating the coupling element 49, enables translation thereof, to move from a release position retracted laterally with respect to the second rod 31″ of the front wall 31 to a position constrained on the second rod 31″, or a coupling arrangement.

[0066] In this case, the handle of the selector 48 ends on one side with a protrusion that determines the formation of a seat 48′ shown in FIG. 13 that forms a sort of hook adapted to retain the upper wall 35 that acts as a roof, being inserted, as in the case of the handle of the pawl 40, between two of the parallel rods that form the grid of the upper wall 35 and locking on a transverse rod in order to retain the upper wall when the selector is moved to the locked position.

[0067] Both the pawl 40 and the sliding selector 48 have a dual function: whereas the coupling element 37 is positioned and fixed on the front and upper corner of the two vertical side walls 33 and 34, when they are in a closed position they retain both the roof 35 and the front wall 31.

[0068] The rotatable pawl 40 can also adopt three positions: a completely closed position in which it locks both the roof 35 and the front mesh 31, a partially closed position in which it locks only the roof 35, leaving the front wall 31 free and one open, in which it leaves both roof 35 and front mesh 31 free.

[0069] According to further possible embodiments, the cage usable in the system according to the invention, being of modular type, can increase in volume by approaching one of the sides from which one of the mesh walls has been removed, generally one of the side walls 33 or 34, a further portion or extension, as shown in FIGS. 15, 16, 17 and 18.

[0070] In this case, a bracket 50 shown in FIGS. 15, 15A, 16D, 17D and in the details of FIGS. 19-19E is used to join two consecutive adjacent vertical mesh walls and simultaneously two adjacent consecutive roof portions, maintaining the opening features specified above.

[0071] This bracket consists of the junction of two coupling elements 37 disclosed above, or comprises a central body 51 provided with two opposite specular and symmetrical pawls that are each provided with a respective handle and respective shaft at the ends of which that are opposite the handles respective coupling elements 54 and 55 are arranged.

[0072] Moreover, at the central portion of the body 51 a tooth 56 is present facing an elastic tongue 57, in which said tooth 56 and tongue 57 form a seat with a vertical axis in which the most external vertical rod 31′ is temporarily housed and fixed of the front wall 31 that is placed next to the extension portion.

[0073] The cage assembly system for pets according to the present disclosure further involves using two further components.

[0074] The first component, shown in FIG. 5, consists of a rear hinge 60, which consists of two parts 61 and 62 that are connected together in an articulated manner that are connected to the roof 35 and to the rear mesh wall 32 and operate as a hinge to constitute an articulated connecting element between the roof and rear wall.

[0075] The part 62 of the rear hinge 60 that forms the vertical portion coupled with the rear wall comprises a tooth that cooperates with a respective portion of the part 61, to constitute a limit stop that enables the mesh to remain open according to an indicative angle of 100°, i.e., partially facing backwards with respect to the vertical of the rear mesh wall. The hinge 60 was so extended that if the user forces the roof beyond 100°, the hinges do not break, but open so as to permit reassembling.

[0076] A second component is represented by a front hook 70 shown in FIG. 5 and in the detail of FIG. 5D. It is a coupling element consisting of two parts 71 and 72 connected and articulated together, in which the part 71 has a substantially horizontal arrangement and comprises fixing means for fixing to the roof 35 of the cage, whereas the part 72 has an arrangement that is variable from vertical when it is in the position of fixing to the upper edge of the front vertical mesh wall 31, to horizontal when released from the edge.

[0077] The front hook 70 has a dual function: when the part 72 is open and raised it acts as a handle to facilitate the opening of the roof 35, whereas when the part 72 is lowered to the closed position it locks the front wall 31 by coupling the front wall 31 with the edge of the roof 35. In this manner a dual problem is solved: the roof 35 is prevented from moving upwards because it is constrained to the front mesh 31 and the roof 35 is prevented from being able to descend or flex downwards because it rests on the front wall 31.

[0078] According to the embodiment shown in FIGS. 20-20C, in replacement of coupling elements 37 and 38 that connect the corners of three adjacent walls, two coupling elements 80 and 81 are used, each of which is applied by respective fixing bodies 82 and 83 to the orthogonal adjacent edges placed near the front corners of the side wall 33 or 34 and comprises temporary coupling means 84 and 85 coupling respectively with the upper wall 35 and with the front wall 31.

[0079] Said provisional coupling elements 84 and 85 are constituted by a rotatable or sliding pawl, that is able to move from a release position with respect to the upper horizontal wall 35 and to the front wall 31 to a locked position in which the respective handles with which the pawl is provided are coupled by rotation or movement on the rods of the respective upper 35 or front 31 horizontal walls.

[0080] As is possible to note, the coupling system disclosed above reaches the important advantageous objectives disclosed and in particular permits opening of the roof 35 in a stable manner at 100°, leaving however the four side walls fixed in place so as to contain the animal securely, and further permits complete removal of the front wall, leaving the roof closed or open, according to need.
