Description

Improvements to connection devices for

perforated profiles.

  The invention relates to devices intended for

  born to connect end & end of perforated profiles, and in particular metal gutters at least the bottom of which is pierced by at least one longitudinal row of

  perforations, gutters commonly used to support

  carry layers of electrical cables.

  It will be recalled that these end-to-end connections of profiles are generally made using flat plates or plates or folded in angles which are fixed to the profiles to be connected by bolting of bolt-nut systems or by folding down of legs previously introduced. in perforations of said profiles. These connections are long and tedious and

  they require the use of special tools to

  Make the necessary screw connections or drawdowns.

  The invention aims, above all, to eliminate these drawbacks, the proposed devices allowing

  to ensure the desired connections in a particular way

  particularly simple and fast, without other accessories and

without tools.

  To this end, the connection devices of the kind in question according to the invention are essentially

  characterized in that they consist of splints

  its in the form of angles of which a first wing is

  arranged to be applied against a side wing

  line of each of the two profiles to be joined, over the entire height of this lateral wing and to be hung on

  the latter pivotally by mu-

  tuel of their free edges and whose second wing

  has a row of deformed portions suitable for co-

  act like ratchets with some of the perforations

  tions in the funds of the profiles to be joined.

  In preferred embodiments, we have

  further recourse to one and / or the other of the provisions

  following: - the deformed portions of the splint are semi-punctured legs therein, - the deformed portions of the splint are embossed bosses therein, - each deformed portion of the splint protrudes from this one of a height at most equal to the thickness of the bottoms of the profiles to be joined, - the perforations hollowed out in the bottoms of the profiles

  are elongated longitudinally, the deformed portions

  bars of the splint are distributed in an equal or multiple pitch of the pitch of distribution of the perforations and these

  deformed portions have a longitudinal dimension

  nale lower than that of the perforations, - the splint is intended to cover externally the profiles to be joined and the edge of the first wing of

  this splint is folded down in a semi-circular profile

circular or substantially such.

  The invention comprises, apart from these arrangements

  main provisions, certain other provisions which are preferably used at the same time and which will be

  more explicitly question below.

  In what follows, we will describe some preferred embodiments of the invention with reference to the accompanying drawings in a manner which is of course not limiting.

  Figure 1, of this drawing, shows a

  pective from above one end of a perforated gutter

  equipped with a connection splice according to the invention.

  Figures 2 and 3 show in cross-section

  dirty on an enlarged scale a detail of this assembly

in two variants.

  Figure 4 is a diagram illustrating the assembly

  of the above joint on each gutter.

  Figure 5 shows in perspective view from below one end of a perforated gutter fitted with a

  another connecting splice according to the invention.

  Figure 6 is a diagram similar to that of Figure 4 and relating to the assembly of Figure 5. The profiles & connect illustrated are

  wiring gutters 1 U-shaped, not only of which-

  ment the bottom 2, but also the wings 3 are perforated with

  longitudinal rows of lights 4 elongated longitu-

ultimately.

  To connect these gutters end to end, two identical fishplates 5 are used, one for each side. Each splint 5 is constituted by an angle

  in L presenting a vertical wing 6 and a horizontal wing

zontal 7.

  The vertical wing 6 is dimensioned so as to be able to be applied against the entire height of each wing 3 of the gutter, but not beyond this height, and to pivotally hang on this wing at

level of its edge.

  The pivoting hooking mode differs depending on whether the splint is external ", that is to say intended for

  wrap the gutters on the outside, or "interior

  "", that is to say intended to be housed indoors

laughing gutters.

  In the first case, illustrated in FIGS. 1 to 4, the upper edge 8 of the wing 6 is folded inwards according to a rounded profile extending over 180 ′ or even more, the flap 8 thus obtained being clean

  styling the upper edges 9 of the wings 3 of gutter

  res. These upper edges 9 are advantageously thickened in a manner known per se, for example in the illustrated manner, which has been described in the patent.

France no 80 05840.

  In the second case, illustrated in Figures 5

  and 6, the upper edge of the vertical wing 6 of the

  the fishplate is preferably further thickened by folding down at 10, which stiffens the said wing and makes it easier to handle the fishplate by hand.

  In this case, moreover, the upper edge of each

  that wing 3 of gutter is folded in 11 towards the interior

  laughter of the gutter with a profile wide enough to cover the upper edges 10 of the vertical wings 6

fishplates.

  The horizontal wing 7 of each splint is

  ribbing of protuberances 12 aligned longitudinally and projecting slightly from said wing upwards in the case of FIGS. 1 to 4 and downwards in the case

Figures 5 and 6.

  These protrusions 12 are dimensioned and

  posed in such a way as to be able to react to the way of cli-

  quets with the perforations 4 of the gutters to be joined

  during the installation of the fishplates on these gutters

  res. The protrusions 12 are therefore distributed according to

  a step equal or multiple to that of the perforations.

  They are formed by local deformation of

the horizontal wing 7 concerned.

  These are for example semi-punctured legs, as visible in FIGS. 1, 2, 4, 5 and 6 or else

  embossed bosses, as seen in Figure 3.

  These protrusions have a height at most equal

the thickness of a bottom 2.

  In the case where the fishplates and profiles are

  made up of sheets of the same thickness, said height

  tor is practically equal to this thickness: in other words, in the case of semi-punctured legs, the

  cut edge of each leg is adjacent to the door

  tion of surrounding sheet metal, with training at most

  an almost invisible slit between them.

  The protrusions 12 preferably have a profile

  asymmetrical transverse in the sense that they are

  limited, on their face intended to cooperate with the

  gutter, by two ramps, one of which is strongly

  inclined on the mean plane of the horizontal wing 7 while the other is only slightly inclined on this plane: in the case of the external fishplates ", it is the ramp facing the vertical wing 6 of the fishplate which is strongly inclined whereas it is the reverse for

interior ribs ".

  This asymmetrical drawing of the protrusions 12

  facilitates assembly and makes it irre-

  versible & snap-on way.

  Said mounting is ensured in the following manner.

  We start by placing the two gutters to be connected end to end in the extension of one another. In the case of the external fishplates (FIGS. 1 to 4), one begins by covering the juxtaposed portions of the two edges 9 with the flap 8 of a fishplate then inclined on the horizontal, as well as visible on the

figure 4.

  Then straighten this splint by rotating it in the direction of the arrow F around the horizontal line of contact between the edge 9 and the flap 8, which brings the horizontal wing 7 closer to the bottom 2, under the latter, then made slide the ridges of the protrusions

  12 of said wing 7 along said bottom 2 up to the

  elastic tent of these protuberances 12 in the perfo-

rations 4 opposite.

The assembly is then completed.

  The assembly obtained is very solid since the release of the protrusions 12 out of the perforations 4

  would require the use of special pressing tools.

  It should also be noted that the assembly in question

  tion was carried out very simply and very quickly, without the assistance of any additional tool or accessory, which constitutes a capital advantage of the invention. It can also be noted that no protrusion protrudes & inside the joined profiles, which allows sliding without any hindrance of

cables-in these profiles. -

  The assembly process is completely

  maple in the case of the illustrated interior ribs

in Figures 5 and 6.

  In this case, the initial attachment of the splint 5

  on each wing 3 of gutter is obtained by introducing

  sant the upper edge 10 of this splint, then incli-

  born, under the flap 11 of the gutter, then in demand

  both the splint upwards to ensure the contact of the

  edge 10 against the flap 11 and by rotating the

  slides in the direction of the arrow G around the line or zone defining said contact, until the two vertical wings are applied one against the other and at the same time

  snap-in time of the protrusions 12 in the perfo-

corresponding 4 rations.

  In each of the two cases described above, the

  perforations 4 used for the snap are adjacent

  nes of the base of the wing 3 of the profile concerned and the pressure of this snap-fastening is due to the fact that the heights, practically identical, of the two gutter wings 3 and of splint 6 pivotally mounted one on the other remain rigorously constant during assembly and after it, these two wings taking support

  one on the other and resistant without deformation, respect-

  in terms of tension and compression in the case

  external ribs and respectively to the compression

  tension and in the case of internal splints

  laughing. To ensure a very intimate application of

  fishplates against the facing faces of the profiles &

  to butt, it may be advantageous to give the angle formed by the two wings of each splint a value a little different from 90 ', namely slightly less than 90' in the case of external splints and on the contrary

  a little more than 90 'in the case of internal fishplates

  laughing: the splicing then results in a slight elastic opening of the ribs in the first case and by a slight elastic closing of the ribs in the

second case.

  To make possible a certain adjustment of the longitudinal position of each splint relative to at least one of the two profiles to be butted, the protuberances are given a longitudinal dimension smaller than that of the perforations which receive them: this measure makes it possible to join together runners with perforations of different dimensions and / or spacings, and / or to provide, as desired, little or no longitudinal play between the runners butted together using the fishplates

considered.

  The number of protrusions, of each splint, cooperating with each profile is preferably at least

equal to 2.

  Of course, in all cases, the distance between the protrusions 12 and the vertical wing 6 of the corresponding splint is equal to the distance between

  the perforations 4 intended to receive these protuberances

  these and the adjacent wing 3 of the corresponding perforated profile so that, at the moment of the snap-in, the two

  wings 6 and 3 are applied one against the other.

  Following this, and whatever the embodiment adopted, we finally obtain a device

  for connecting perforated gutters, the

  tution, implementation and benefits result

enough of the above.

  As it goes without saying, and as it results from

  their already from the above, the invention is not limited

  in no way to those of its modes of application and implementation

  which have been more specifically contemplated; on the contrary, it embraces all variants, in particular those where the perforated profiles to be connected end to end are not U-shaped monobloc gutters,

  but sets made up of lateral angles

  the L-shaped ones joined together by spacers, the

  sides being then mounted on the lateral angles

the.
