Definitions
- This invention concerns a holder for cable trays according to the preamble of claim 1.
- a problem with the known solution is that a holding force which is exerted of such a downward folded locking tongue against a co-operating metal wire is limited by such parameters as material thickness of the holder, the width of the tongue and the flexibility of the material in the tongue.
- the locking tongue can be formed and dimensioned for its task, namely to lock a cable tray in the holder, without this having to affect the dimensioning of the holder itself with respect to material thickness, width of the holder etc.
- Fig. la, b shows a holder according to the invention formed as a pendulum holder
- Fig. 2a, b shows a holder according to the invention formed as a bracket
- Fig. 3 shows the holder according to Fig. 1 in engagement with a cable tray intended to be supported
- Fig. 4 shows a detail of Fig. 3 in an enlarged scale.
- a pendulum holder 1 is shown, that is the holder is intended for being suspended from for example a ceiling via a not shown supporting means, which is fastened, for example in the square hole 2, centrally on the holder 1.
- the holder 1 has a first wall 3 and two second walls 4 and 4' extending at right angle against the first wall 3, for forming an upside-down turned U-profile in use.
- each slot 5 Distributed along its length there are arranged recesses going out from the first wall 3, which go over to slots 5, each having a width for reception of a metal wire of a cable tray.
- a remaining portion of the first wall above each slot 5 comprises an engagement portion 6, which together with a slot edge 7 directed against the engagement portion 6 in &ach second wall as well as a slot bottom 7' defines the slot 5.
- the outermost engagement portion 8 is for-med with a cut-out locking tongue 9, having a general direction at an- angle to the general extension of the engagement por ion 8, as seen from its bottom 1 ' .
- the locking tongue 9 is bend-able in towards the associated slot 5' for locking engagement with a metal wire positioned in this slot which will be desc ribed in more detail below.
- Fig. lb shows the pendulum holder 1 in a perspective from below for the sake of increased clarity.
- Fig.2a shows an alternative holder 11 for cable trays , which holder is in this case formed as a bracket for fasten ing to a wall, a pole or the like.
- the holder 11 displays a conventional bracket shape, that is having a (here enforced) , power receiving side 12 and a fastening po tion 13 for contact against said wall or pole.
- the bracket 11 is manufactured in one single piece having bends between the first wall 3 an «d two second walls 12 and 12' (analogous with the pendulum bolde in Fig. la, b) and with a bend between the second wall 12 and the fastening portion 13.
- Fig. 2b shows the bracket 11 in a perspective view from below for the sake of increased clarity.
- Fig. 3 shows the pendulum holder 1 in Fig. la in a using position, however, without a support means in the form of a suspension device for suspension from a ceiling or the like.
- the cable tray 14 intended to be secured is of the previously known kind which consists of a number of longitudinal 15 and transversal 16 metal wires, which are joined to each other in respective cross points.
- the transversal metal wires 16 are, at their end regions, bent upwardly for forming an essentially shallow U-shaped chute profile in section.
- Fig. 3 From Fig. 3 is shown that the longitudinal metal wires 15 are inserted into a respective slot 5 below an engagement portion 6.
- the outermost metal wire (to the left in Fig. 3), of the ones that are in the same plane, co-operates with the outermost slot 5' and is fastened by a downwardly bent locking tongue 9.
- Fig. 4 the area for fastening is shown in an enlarged scale, wherein the metal wire 17 thus is in co-operation with the bent-down locking tongue 9, which is bent down along a bending line 18, which is essentially at a right angle to the extension of the metal wire 17.
- the engagement edge 10 forms an acute angle, which in this case is the same as the acute angle ⁇ limiting the locking tongue, with the axis of the metal wire 17, wherein by bending down the locking tongue, this engagement edge 10 will come into engagement with the metal wire 17.
- the angle is chosen so small that the engagement between the locking tongue 9 and the metal wire 17 will become self-locking, that is that possible vibrations and other movements of the metal wire 17 do not cause the locking tongue 9 to bend back to an initial position where it comes in the • same plane as the first wall 3.
- the edge of the locking tongue which engages the metal thread is provided with a friction increasing element such as grooves for increased engagement security.
- Locking tongues corresponding to the locking tongue 9 on the figures may be present on plural engagement portions on one and the same holder. Locking tongues may be formed differently, possibly with otherwise disposed angling and bending line.
- Bending initiators could be formed otherwise with for example an impression in the material, one or more holes etc.
- the shape of the first, as well as the second walls, may be made differently. Possibly it could be sufficient with one single second wall in certain applications.
- the holder is formed in one piece with holes and bends, but it is not excluded that it is manufactured from plural joint parts, whereby for example the walls are separate parts from the start and, in case of a bracket holder, the fastening arrangement is formed in another way.
