Flexible cable guide with two-directional joints

In office furniture, such as desks, work desks and the like, as in other pieces of furniture, there is a requirement to have devices of various kinds, which require electrical power and / or communication, using electrical cables, with other devices, physically removed from them.

Examples of such devices are telephone sets, calculating machines, computers, lighting devices, etc., which are often also present on desks and similar furniture.

Isbo has the consequence that there are a large number of cables that are intended to connect different areas of the furniture and that it is desirable, both for aesthetic and safety reasons, that they are not directly supported by the furniture itself.

Therefore, there is a need to have a cable gland B that allows these cables to be housed in a single element »keeping them aligned and separated from each other and that can also be arranged according to the profile of the wall of the furniture that it must support said cable gland, however having variations in direction.

These results are obtained by the present invention, which provides for a flexible cable gland which consists of a number of double T-shaped elements, with curved flaps, defining aligned cylindrical spaces, separated from each other by the central core of the profiled element, connected to each other by bidirectional articulations, in the cylindrical spaces delimited by the curved flaps, several electrical power, communication and similar cables can be housed.

Each of the profiled elements has on each of the base surfaces a pair of fins protruding from the central core parallel to the axis of the element itself, spaced apart from each other, suitable for articulating at the end a pair of feet of a hinge element, consisting of an annular body with two pairs of pins protruding radially in perpendicular directions, the fins of a contiguous profiled element, rotated by 90 °, can be connected to the second pair of legs of the articulation element, in relation to the previous one, constituting the pairs of fins and the articulation element connected to them, the bidirectional articulation, cardan type , connecting B contiguous profiled elements.

The core of the profiled element has an axial hole which, in the assembled well, is aligned with the central hole of the hinge element, and a reinforcement cable can be inserted into these aligned holes.

In the middle position of the flaps of the profiled element there is a collar with recessed edges in squared, this collar being able to accommodate by locking profiles fixing the cable gland in the fixed elements.

More details can be seen in the description below, with reference to the accompanying drawings, the figures of which represent »

As shown in fig. 1, 2 and 3 »the cable gland according to the present invention consists of an articulated chain of profiled elements, which is flexible in all directions; the articulated elements have suitable seats to house and maintain in position, in an orderly manner and several electrical and communication cables.

In particular, the cable gland comprises several profiled elements (1) connected to each other with the interposition of a hinge element (2); or the articulated elements (1). or the hinge elements (2), as best seen in figs. 4 and 7 »are drilled axially and a central guide cable (3) can be inserted into that hole.

Each element (1) is constituted by a body substantially in the form of a double T, in which the opposite flaps (4) are curved towards each other, to form, in cooperation with the central core (5). four delimited spaces (6), substantially cylindrical, intended to receive cables, accessible from the outside through the open part (7).

Saliênoias are performed in the central soul (θ)

- 3 provided at the end of a hole (9a), as shown in figs. 4 to 6 or, as shown in figs. la}, provided with a recessed end fork (9b); in the holes (9a) or in the forks (9b) the opposite radial blades (10a) of the hinge element (2) are inserted by means of a ring body, from which two pairs of perpendicular blades radiate outwards (10a) and (10b).

The feet (10b) insert into the holes or forks of a next element (1), which is rotated by 90 ° with respect to the previous one, forming a cardan-like joint, which allows the axes of the two profiled elements (1) to be oriented at a certain angle to each other on any plane: the paBsa-caboB organ according to the present invention is therefore constituted by a number of profiled elementsB and of articulation elements alternately linked together, constituting a flexible structure, suitable to be bent according to the needs, as illustrated in the section represented in figs. 1, 2 and 3 ·

The spaces (6) of the consecutive profiled elements (1) are aligned with each other and can therefore accommodate each one or more cables (11), indicated in dashed lines in fig. 4, which are alternately separated by the web (5) »from the following profile elements (1).

The insertion and extraction of the cables (11) inside the cable gland are made through the opening (7), taking advantage of the flexibility of the cables themselves and the cable gland; through the opening (7), cable shifts can also be passed to a device known per se, or new cables introduced in an intermediate position in the cable gland.

Conveniently, the flaps (4) of the profiled body (1) have the collars (12), substantially cylindrical, with outer edges recessed and sub-squared with respect to the maximum width of the collar; in that collar, which is aligned with those of the contiguous profiled elements rotated by 9θ ° »with

the openings (7) »can be inserted by fitting profiles (13) or similar, through which the cable gland can be fixed on fixed or mobile structures, walls and the like, with glue, screws, by fitting or similar means of fixation, in relation to the surface on which the profiles will be fixed (13).
