Stackable saddle of the perfected type for supporting elongated bodies

Abstract

A saddle for supporting elongated bodies has a body with a quadrangular section, on the opposite sides of which wedge-inserted coupling members are provided, to couple the saddle with another saddle, so as to have the reciprocal stacking of these saddles on a support. A saddle according to the invention offers the advantage over known saddles of being stacked on previously installed saddles due to the presence of incorporated members which allow their connection, without resorting to the use of tools or similar auxiliary equipment.

Description

(1) These and other objectives, advantages and features are evident from the following description of a preferred embodiment of the saddle of the invention, shown, for illustrative and non-limiting purposes, in the figures of the enclosed drawings. In which:

(2) FIG. 1 illustrates a cable clamp of the known art wherein the saddles are withheld by means of a jumper;

(3) FIG. 2 illustrates another example of a cable clamp of the known art, with saddles held in position on a respective support by means of a threaded bar screwed onto a clamp;

(4) FIG. 3 illustrates a perspective view of an embodiment of the stackable saddle of the invention;

(5) FIG. 4 illustrates a plan view the saddle of FIG. 3;

(6) FIG. 5 illustrates the saddle of FIG. 4 in a section A-A;

(7) FIG. 6 illustrates the stacking phase of an additional saddle of FIG. 3 on a previously installed saddle;

(8) FIG. 7 illustrate a sectional view of a cable clamp with a plurality of saddles stacked according to the invention;

(9) FIG. 8 illustrates the cable clamp of FIG. 7 with the cables assembled in operation;

(10) FIG. 9 illustrates an embodiment variant of the saddle of the invention with a system of extractable cable clamps;

(11) FIG. 10 illustrates the saddle of FIG. 9 with a view from A;

(12) FIG. 11 illustrates an exploded view of the saddle of FIG. 9; and

(13) FIG. 12 illustrates the saddle of FIG. 11 with a view from B.

(14) The cable-clamp device 1 of the known art, illustrated in FIG. 1, comprises a plurality of saddles 2, each composed of a pair of half-saddles 2a, 2b which form, by joining them, the seat for sustaining the respective cable 3.

(15) The cable clamp 1 provides a jumper 4, fixed on a respective support 5 by means of a screw 6, for sustaining the saddles 2. It is therefore evident that when additional saddles 2, with respect to those already operating, are to be assembled on the cable clamp 1 of FIG. 1, the jumper 4 must be completely substituted by another having a greater length.

(16) In the embodiment illustrated in FIG. 2, also forming part of the known art, the saddles 2 are reciprocally stacked on a threaded bar 7, in turn sustained by a clamp 8 for connection with the support 5.

(17) In this case, if a saddle 2 is to be added to those already present on the cable clamp, the nut 9 of the threaded bar 7 must be disassembled, and the length of the bar must be such as to be able to also receive the saddle or saddles added to the previous ones.

(18) In order to overcome the drawbacks of the known art described above, the saddle of the invention, indicated as a whole with 10 in FIG. 3, substantially consists of a body having a quadrangular section 11, made of plastic material (a cube or other body having the form of a rectangular parallelepiped in general), on two opposite sides 12a and 12b of which the stacking means of the saddles are provided, whereas means for fixing the cables 3 are present on two other opposing sides 13a and 13b.

(19) In particular, the above-mentioned stacking means provided on the side 12a of the body 11 consist of slides 14a, 14b having, for example, a substantially L-shaped section, whose size and arrangement are such as to be wedge-inserted inside corresponding seats 15a, 15b provided on the side 12b of the body 11 of the contiguous saddle 10 and closed in correspondence with their side 15c opposite to that 15d for the insertion of the slides 14a, 14b (FIGS. 6-8).

(20) As can be seen from the section of FIGS. 5 and 7, the body 11 is longitudinally crossed by a hole 16 for housing a screw 17, whose head 18 rests on the abutment 19 of the hole 16 to effect the anchoring of the first saddle 10a of FIG. 7 on the clamp 8, in turn tightened on the respective support 5.

(21) In this embodiment, the stacking of a new saddle 10b on that 10a already installed on the cable clamp, is effected by the wedge-insertion of the slides 14a, 14b of the saddle 10a, inside the seats 15a, 15b of the saddle 10b immediately following (FIGS. 6-8).

(22) As better illustrated in FIGS. 3 and 8, the saddle 10 of the invention has, on the side 13a, elastically deformable arms 20, suitable for being elastically tightened around a first cable 21. On the opposite side 13b of the saddle 10, analogous arms 22, 23 are also provided for sustaining respective cables 24 and 25.

(23) It should be understood that the invention is not limited to the embodiment illustrated in these figures, as the saddle 10 can have a different number of arms 20, 22, 23 for forming corresponding seats for as many different cables.

(24) Furthermore, in order to prevent the cables 21, 24 and 25 from becoming detached from the respective arms 20, 22 and 23, the saddle 10 of the invention comprises a flexible flap 26 on the side 13a and an analogous flap 27 on the side 13b of the above-mentioned body 11. The flaps 26 and 27 are fixed at one end, to the respective side 13a, 13b of the body 11, whereas the opposite end 28, 29 is suitable for being engaged on the respective withholding means 30, 31. In particular, the above-mentioned withholding means 30 are positioned on the arm 20a of the saddles of FIG. 6, whereas the withholding means 31 are positioned on the arm 23a of the same saddles of FIG. 6. In this way, the closing of the cables 21, 24, 25 is obtained inside the respective arms 20, 22, 23 by the connection of the flaps 26, 27 on the respective withholding means 30 and 31.

(25) The end 28, 29 of the flaps 26, 27 is advantageously provided with a toothing 32, whose function is to ensure the grip with the withholding means 30 and 31, also in the presence of cables having a different diameter.

(26) In the variant of FIGS. 9 to 12, the saddle of the invention has a modular structure, in which extractable cable clampers 47 and 48 are blocked on the quadrangular body 11. In particular, grooves 33 and 34 are formed on the body 11 of the saddle of the invention, inside which corresponding cursors 35 and 36 are engaged, by inserted sliding, which are T shaped in the example illustrated. These cursors are, in turn, fixed to respective bases 37 and 38, in turned equipped with corresponding deformable arms 39 and 40, substantially analogous to the arms 20, 22 and 23 of FIG. 3.

(27) Thanks to the modular structure of the saddle of the invention with extractable cable clampers 47 and 48, different cable clampers can be assembled on the same body 11, compatible with equivalent different types of cable, in form, dimensions, weight and so forth.

(28) In the variant of FIGS. 9 to 12 the saddle of the invention provides, in place of the flaps 26, 27 illustrated in FIGS. 3 to 8, corresponding caps 41, fixed, at one side, to the end of one of the deformable arms 39 and 40, the other side, however, being left free, so that it can be snap-closed on the cable housed inside the respective cable clamp 47, 48.

(29) As better illustrated in FIGS. 9 and 10, elastic flaps 43a, 43b are advantageously provided inside the seats 15a, 15b, for the slides 14a and 14b, whose function is to cooperate with respective housings 44a, 44b provided on the same slides 14a, 14b. The reciprocal blocking between stacked saddles 10a, 10b is thus effected bidirectionally, thanks to the contribution of the system described of flaps 43a, 43b and housings 44a, 44b with the above-mentioned closing on the side 15c of said seats 15a, 15b.

(30) An analogous system with elastic flaps 45a, 45b positioned inside the body 11 of the saddle of the invention, and with housings 46a, 46b provided on the cursors 35, 36 is used for, blocking the same cursors 35, 36 of the extractable cable clamps 47, 48 inside the respective grooves 33, 34 of the body 11 of the saddle 10, in which said grooves are closed at their ends 49, 50.
