In general terms, the present invention refers to a device for the structural closure and fastening of folders that comprises a reciprocal set of coupling means (2a)(2b) which, provided with insert fasteners (6)(13) and fixation means (9)(9a)(9b) that are mounted on the edges (23a) of the covers (23), allows the closure of a filing folder (20) keeping a structural fastening that prevents deformations or allows to correct them in case they occurred.
More particularly, the present device (1) is applicable to folders (20) for filing elements such as paper or plastic sheets, laminar elements in general, envelopes, envelopes or cases to keep discs [CD's, DVD's, diskettes], etc. These filing folders (20), usually comprise a back (21) or central part in which an inner face has a set of fastening means or hooks (22) intended to insert the holes of the elements to be filed. From the longitudinal edges (21a) of the back, (21) the mobile covers (23) project—towards both sides—and their mobility allows the opening and closure of the folder (20). Each cover (23) is limited by an outer face (23c), an inner face (23b) and external edges (23a).
The present device (1) comprises a set of reciprocal coupling means (2a)(2b) integrated by a first (2a) and second (2b) coupling means which, in the present embodiment, are of the box and pin type. These coupling means (2a)(2b) comprise a set of bodies (4)(5) which, as an elastic broach, are pluggable by means of the forced wedging until the assembly of an elastically releasable cramp (10a)(11a).
The first coupling means (2a) comprises a first body (4) which, on the one hand, forms a fixation base (6) to the folder (20), whereas, on the other hand, has cramping elastic arms (10) which free ends form two cramping heads (10a). These elements constitute the pin part of the coupling.
The second coupling means comprises a second body (5) which, on the one hand, form a fixation base (6) to the folder (20), whereas, on the opposite part, forms a forced wedging cavity (11) which constitutes the box part of the coupling.
At the bottom of the above-mentioned forced wedging cavity (11), there are some cramping edges (11a) intended to the cramping heads (10a) of the first coupling means (2a). Quite behind, there are some cramping releasing terminals (12a) which project from the elastically conveying cramping releasing arms (12).
The forced wedging cavity (11) presents a progressive widening from the entrance or stop (3), so that said progressive widening constitutes a cooperating means with the functionality of the coupling means (2a)(2b) [when it couples, it gradually compresses the elastic cramping arms (10) and when it decouples, it cooperates with said decoupling].
On the other hand, both fixation bases (6) have a contact wall (7) that contacts the inner face (23b) of the cover (23). This contact wall (7) can be provided with non-slip means such as, for instance, some protruding embossments that can be sharpened so that their action against the cover (23) prevents undesirable movements.
The fixation bases (6) also have anchorage openings where some fastening clips (13) are anchored. The latter (13) can be comprised by elastic laminar means [for example, they can be structured in resistant and elastically flexible metals].
In this manner, the contact wall (7) and the fastening clip (13) complement each other to form an insert fastener which fastening cavity (14) or wedge is prepared to receive the external edge (23a) of the cover (23), on which they act as a fastening little claw.
The fastening clip (13) is folded so that a fastening sector or body (13a) and an anchorage sector or body is distinguished (13b).
It has been provided that the anchorage body (13b) of the fastening clip (13) has a set of alternative positional anchorage means (8a)(8b), which, as positional variation means, are situated in the anchorage opening (8) of the fixation base (6).
The anchorage body (13b) also has an anchorage hole (13c) to allow the action of the fixation means (9)(9a)(9b) constituted [for example] by fixation screws (9b) which, placed into fixation ducts (9a) that cross the fixation bases (6), are capable of projecting and exerting pressure on the part of the cover (23) able to be inserted in the fastening wedge or cavity (14). Upon crossing the hole of the fastening clip (13), the fixation screws (9b) also form part of the anchorage of said clip (13) in the fixation base (6).
To place the present device (1), the edges (23a) of the covers (23) are inserted in the fastening cavity (14) of the insert fasteners formed by the fixation bases (6) and the fastening clips (13). In these conditions, the contact walls (7) remain attached to the inner faces (23b) of the covers (23), whereas the fastening bodies (13a) of the clips (13) stay attached to the outer faces (23c) of said covers (23) of the folder (20).
The fixation screws (9b) are placed in the fixation ducts (9a) so that, projecting themselves through the anchorage opening (8) of the fixation base (6) and through the anchorage holes (13c) of the fastening clips (13), exert pressure on the part of the cover (23) inserted in the fastening cavity (14).
With the device (1) so arranged, the first coupling means (2a) can be inserted in the second (2b), with which, as a mode of elastic broach of forced wedging, said first means (2a) enters until reaching the coupling stop (3). This is possible because the elastic cramping arms (10) are bent by forced insertion and slip within the wedging cavity (11) until the heads (10a) encase into the cramping edges (11a) and said cramp is assembled.
In these conditions, the fastening and fixation exerted by the means described, keep the folder (20) structurally unaltered, preventing its bending, folding or disassembling.
To disassemble the cramp, it is enough to press the releasing arms (12) which releasing terminals (12a) move the cramping heads (10a) from their position against the cramping edges (11a). When the cramp is released, the coupling means (2a)(2b) can be decoupled and the folder (20) can be opened.
It has been provided that the device (1) may have different sizes that facilitate its application to different types of folders (20). For example, that the separation between both insert fasteners (6)(13) is shorter than the width of the back (21) of the application folder (20). In this manner, the folder (20) can be kept adequately closed without the covers (23) being arranged in a parallel manner.
