Description

 DESCRIPTION

MULTIPLE PROTECTION TUBULAR CASE.

Object of the invention

The present invention relates to a multiple protective tubular sheath, intended to house electrical cables or conduits inside it safely and resistant to friction and mechanical damage.

Background of the invention.

At present, different types of protective covers and conduits are used for the placement of cables and conduits through structures of various kinds.

A usual application of this type of covers is the placement of electrical cables in cars and vehicles in general, which requires that they be wrapped in suitable means for their mechanical protection against friction and their grouping together.

Thus, tubular sleeves comprising a longitudinally open tubular passage, formed from a band of self-closing tissue, are used. This fabric, by its own construction, arches transversely, configuring the tubular passage destined to the housing of the pipes to be protected. This flexible passage allows the cable or inner cables to be placed along the longitudinal side that can be easily opened, instead of requiring the introduction of the cables at one end, such as closed tubes. In the case of introducing several cables or conduits in the sheath, a mallet is formed, which can present problems of cable order and difficulty of handling, which is why sometimes more than one sheath is used, posing a problem of manipulation and space in places of passage and placement.

Description of the invention

The multiple tubular protection sheath, object of this invention, has technical particularities intended to improve the placement and protection of cables and conductors through structures, such as in automobile bodies or the like. Thus, the sheath of this invention comprises at least one band of self-closing tissue, connected by a corresponding means of connection, arranged longitudinally, to a second band of continuous fabric, at least one end of the band of self-closing tissue protruding from the less a longitudinal side of the corresponding joining means, for the conformation of longitudinally open tubular passages to house cables and conduits, individually or in independent mallets.

In this way, the sheath allows to define multiple tubular passages, longitudinally open and configured on the self-closing fabric band when wound on itself. These passages can be used to accommodate the cables and conduits to be protected, which represents a great advantage in maintaining order and isolating certain cables and conduits from others independently or in small mallets.

The joining means allow the sheath to be more rigid, but in turn, allows the mallets to be distributed in a plurality of smaller mallets, so that it gains in handling capacity.

It has been provided that the continuous fabric band, the self-closing fabric band or bands and the longitudinal joining means are constituted in a single piece by knitting by warp or by knitting weaving. Thus, in a warp-knitted embodiment, the sheath can be made in a double-type "Raschel" type machine. At the same time, in case of carrying out the cover by means of openwork weaving, cinteria machines can be used.

In a first configuration of the sheath, the main band has a chain structure knitted with tricots positioned so that the fabric is stabilized flat and has no tendency to roll up the ends or edges. In this way, the sheath is left with a flat configuration with the housing bands of the cables and conduits on one side.

In a second configuration said main band has a chain structure knitted with tricots positioned so that the fabric is stabilized with a tendency to wind up the ends or edges concavely, but controlled in the amount of superposition of said ends, the band remaining or bands of accommodation of the cables inside the sheath, accessible by opening said band of the sheath and protected from the outside.

In a third configuration, said main band has a chain structure knitted with tricots positioned so that the fabric is stabilized with a tendency to wind around the edges in a convex manner, but controlled in the amount of overlapping of said ends or edges, leaving the band or bands of accommodation of the cables in the exterior of the cover, accessible completely independently.

To facilitate the placement of the multiple sheath, it is provided that in the area of the joining means between both bands of fabric there are through holes through said bands of tissue suitable for enabling the fixing of the sheath by means of fixing means adequate. Thus, through these holes mechanical means can be placed, such as screws, pivots or adhesives.

For example, in an embodiment of the sheath with two passages, two bands of fabric are used, which have the ends oriented facing each other and partially overlapping, for the formation of the two parallel and independent tubular passages on both sides of the means. of Union. The cables to be protected can be placed independently in the two tubular passages, entering one through each lateral opening configured by the opposite ends of the fabric bands.

In any of the three configurations of the continuous, flat, concave or convex fabric band, the sheath can have a plurality of self-closing fabric bands, said self-closing fabric bands forming a series of parallel tubular passages, whether lateral, internal or surrounding exteriors, according to the aforementioned configuration of the continuous fabric band.

To complement the description that is being made and in order to facilitate the understanding of the characteristics of the invention, a set of drawings is attached to the present specification in which, for illustrative and non-limiting purposes, the following has been represented:

Figure 1 shows a cross section of a sheath that presents the band of continuous fabric configured in a flat manner - Figure 2 shows a cross section of a sheath that presents the band of continuous fabric configured convexly with respect to the self-closing band.

Figure 3 shows a cross section of a sheath that presents the continuous woven band concavely configured with respect to the band self-closing

Figure 4 shows a perspective view of one end of a sheath with two passages and the flat continuous web of fabric.

Figure 5 shows a view analogous to the previous one with the band of continuous fabric curved on the self-closing band for the configuration of two opposite passages.

Figures 6, 7 and 8 show similar views to those represented in Figures 1, 2 and 3, but with multiple self-closing lateral, interior and exterior bands. Preferred embodiment of the invention

As can be seen in the referenced figures, the sheath of the present invention is constituted by at least one band (1) of self-closing fabric joined by an intermediate joining means (2) corresponding to a band (3) of continuous fabric, said said being joining means (2) arranged longitudinally, so that the lateral ends (1a, 1b) of the band (1) of self-closing fabric are protruding with respect to said joining means (2), forming longitudinally open passages (4) for the placement of cables and conduits.
