Covering Box and Hood for Roller Elements

Abstract

A covering box for roller elements, to be fixed to a wall or ceiling, comprises a casing made up of multiple walls that define an internal housing configured to receive the roller elements. A lower hood is provided with a pivot to form an axis of rotation, such that the hood is able to pivot with respect to the casing between a connected state and a disconnected state. The pivot comprises a hollow and a hook-shaped segment configured to be coupled with a segment of the hood. The hollow is defined by a vertical extension that extends from the casing and an elongated horizontal extension from which the hook-shaped segment extends vertically defining a first point of rotation for a first segment of the hood and a curved segment intended to make contact under pressure on a second segment of the hood. An elongated segment protrudes from the elongated extension that defines a second point of rotation for a third segment of the hood.

DESCRIPTION OF A PREFERRED EMBODIMENT

[0026] In light of the aforementioned figures, and in accordance with the adopted numbering, one may observe therein a preferred exemplary embodiment of the invention, which comprises the parts and elements indicated and described in detail below.

[0027] Furthermore, the terms first, second, third, and the like in the description and in the claims are used to distinguish between similar elements and not necessarily to describe a sequential or chronological order. The terms may be interchanged in suitable circumstances and embodiments of the invention may operate in other sequences than those described or illustrated in the present specification.

[0028] Furthermore, the terms upper, lower, up, down, and the like in the description and the claims are used for descriptive purposes and not necessarily to describe relative positions.

[0029] As can be seen, the protective assembly intended to internally house a roller blind (not shown), suitable to be fixed to a wall or ceiling, generally comprises a covering box, generally indicated with the reference (1), and a hood, generally indicated with the reference (2), which can be linked with said covering box (1), which are described in greater detail below.

[0030] Going into greater detail in the covering box (1) for roller elements, suitable to be fixed to a wall or ceiling, and according to FIGS. 1, 2 and 3, it comprises a casing (3) made up of an upper wall and multiple lateral walls such that they define an internal housing (100) intended to house the roller element, including the hood (2) located in the lower portion of the casing (3) provided with pivoting means to form an axis of rotation such that the hood (2) can pivot with respect to the casing (3) between a connected state (i.e., the hood (2) is coupled to the casing (3) in a closed position) and a disconnected state (i.e., the hood is tilted in a substantially vertical position with respect to the horizontal plane).

[0031] Specifically, the pivoting means comprise a hollow (4) and a hook-shaped segment (5) intended to be coupled with a segment of the hood that has a complementary shape, which will be described later.

[0032] The hollow (4) is defined by a vertical extension (30) that extends from a vertical lateral wall of the casing (3) and an elongated horizontal extension (31) from which the hook-shaped segment (5) extends vertically which defines a first point of rotation for a first segment of the hood and an upper curved segment (32) that is intended to make contact with a pressure force on a second segment of the hood (2) during the placement of the hood (2).

[0033] From the elongated horizontal extension (31), an elongated segment (33) protrudes axially aligned with said elongated extension (31) that defines a second point of rotation for a third segment of the hood (2).

[0034] It should be mentioned that the vertical extension (30) is offset with respect to the outermost face of the vertical lateral wall, defining a recess (6).

[0035] The covering box (1) includes coupling means comprising a recessed portion (9) configured to be coupled with a segment of the hood that has a complementary shape, said recessed portion (9) being located above the hollow (4).

[0036] Now, referring to FIGS. 4 and 5 and to the hood (2) for the previously described covering box for roller elements, the hood has a plate (7) with an internal side (70) oriented towards the housing defined by the covering box (1) and an external side (71) opposite to the internal side. Furthermore, pivoting means are provided which form a pivoting axis so that the hood is pivotable between a connected state and a disconnected state relative to the covering box (1).

[0037] As can be seen, the pivoting means are arranged at one end of the plate (7) of the hood (2), having an extension (72) that ends with a hook-shaped segment (73) that acts as the first point of rotation (P1) with a segment of the covering box (1) and a second point of rotation (P2) present in the extension (72) that is linked to a second segment.

[0038] In addition, the hood (2) also includes coupling means comprising a coupling branch (8) with a curved path and a certain flexural degree, which extends from the extension, configured to be coupled to the covering box (1) in a connected state, the end of the coupling branch having a substantially wedge-shaped widening (80) intended to be coupled to the recessed portion (9) in the connected state.

[0039] Due to the arrangement and geometry of the covering box (1) and the hood (2), in the disconnected state the angle (α) formed by a longitudinal axis (EC) of the horizontal elongated extension (31) of the covering box (1) and a longitudinal axis (ET) of the hood (2) is equal to or less than 90 degrees, such as can be appreciated in FIG. 7. In this manner, the geometric configuration of both bodies provides stop means that prevent an angle greater than 90° between the longitudinal axis (EC) and the longitudinal axis (ET) when the hood (2) adopts a hanging arrangement. Consequently, the hood (2) is prevented from causing damage to the facings or glass of a glass window or door when it is in the disconnected state, i.e., hanging.

[0040] FIG. 8 shows the different movements that have to be carried out during the assembly of the hood (2). In this manner, to place the hood (2) in the casing (3) the operator must carry out a first vertical translation movement, and then a second translation movement in a horizontal plane. Subsequently, once a portion of the hood (2) is partially housed inside the casing (3), a rotation movement is carried out such that the respective aforementioned coupling means of the covering box and the protective hood are linked together to keep the hood (2) in a horizontal plane.

[0041] The details, shapes, dimensions and other accessory elements, used to manufacture the box and hood assembly for roller elements of the invention, may be suitably substituted for others which do not depart from the scope defined by the claims which are included below.
