BACKGROUND CF THE INVENTION
1. Field of the Invention The present invention relates to a disconnectible suspension bow for fastening a pipe, a cable or a simi-lar longitudinal object to a supporting structure, said suspension bow being made up of a composite rod-shaped unit, the upper end of which is provided with fastening means for the supporting structure, whilst its lower end, ca~ries a circular element.

BACKGROUND CF THE INVENTION
1. Field of the Invention The present invention relates to a disconnectible suspension bow for fastening a pipe, a cable or a simi-lar longitudinal object to a supporting structure, said suspension bow being made up of a composite rod-shaped unit, the upper end of which is provided with fastening means for the supporting structure, whilst its lower end, ca~ries a circular element.
2. Description of the Prior Art In the prior art, suspension bows have been used in various embodiments. The object thereof is to provide a rapidly and easily mountable structure on the one hand, and to obtain a sufficient strength for taking up the weight of the object to be suspended, on the other hand.
The difficulty with these prior art embodiments, however, is that the mounting is carried out in two steps. First, the object (pipe) is suspended provisional-ly, whereupon f.i. the screw-threaded rod is fastened.
In the second step the bow is put around the pipe; for fastening this bow to the rod, the combination of object plus bow is moved up and down due to the fact that the majority of the bows must be pushed along the rod, star~
ting from the free end of said rod.

, .
~:~3~
Anotker difficulty of the prior art bows, consists in that after a complete or partial mounting of a num-ber of suspension bows, there frequently occurs a slight displacement as a result of mechanical or thermal causes in the object supported,which may give rise to ben-ding stresses or permanent deformations of the suspen-sion bows.
SUMMARY OF THE INVENTION
In view of the foregoing factors and conditions of the prior art it is a primary object of the present invention to provide a suspension bow the supporting structure of which may be fastened to the ceiling, while only then the respective pipe is so arranged thnt the latter is supported at once in its desired position.
It is another object of the present invention to provide a structure which, while maintaining the above mentioned advantages, simultaneously precludes the drawbacks of the prior art structures.
This is attained according to the present invention in that the rod-shaped unit is connected in an adjus-table manner with both the fastening means and the circular element through an all-sided pivotal coupling.
; As a result of these measures, sLight displacements or deformations of the suspended object will be ubsorbed without tensile forces occurring in the suspcnsion struc-ture.
r~5~
In a preferred embodiment of the present inven-tion, the circular element of the suspension bow is provided with two radially protruding tongues adjacent to either side of the rod-shaped unit, which are affixed by a sleeve being slideable with clearance around said element, said sleeve closely fitting around said two tongues. In this embodiment, the tonaues com-prise a recess the end of which is directed toward the rod-shaped element, said element comprising a spheri-cal thickening at that point. This allows a slight angular displacement between the rod-shaped unit, and the circular element co-operating with the object to be suspended.
The features of the present invention which are believed to be novel are set forth with particularity in the appended claims.

DESCRIPTION OF A PREFERRED EMBODIMENT
In order to best understand the present invention a description of a preferred embodiment thereof is provided accompanied by drawings.
Initially referring to Fig. 2, the disconnec-tible suspension bow 1 is intended for fastening a pipe 3 or a similar longitudinal object to a suppor-ting structure 2. The suspension bow is made up of a composite rod-shaped unit 4 which is illustrated in Fig. 1. At the upper end, this unit 4 is provided with fastening means 5 (see Fig. 3) for the supporting structure 2. At the lower end, the unit 4 compxi~es a circular element 6. This element is provided with two radially protruding tongues 7 which are adjacent to both sides of the rod-shaped unit 4. The tongues are held by a sleeve 8, being slideable with clearance along this unit 4 and closely fitting oround both tongues 7.
Referring now to Fig. 1, the rod-shaped unit 4 is connected through an all-sided pivotal coupling 9 with the fastening means 5 and, throvgh an all-sided pivotal coupling 10, also with the circular element 6.
. ~ ~, .
.
~L~L375~5re~;
The ~ffect of these two universal couplings 9, 10 is strated (slightly exaggeroted for the sake of clearness) in Fig. 2. After a provisionol mounting, the pipe 3 may be submitted to a slight displacement, which displacement may be obsorbed by the suspension bow 1 without additional tensions being brought about in the element 6 or in the rod-shaped unit 4. The certerline 11 in Fig. 2 shows the purely vertical suspension, while the centerline 1~ shows that a certain displacement may occur without inconvenience.
The pivotal coupling 10 has been obtained in that near their cnds, the tongues 7 comprise a recess 13 being directed toward the rod-shaped unit 4, said unit comprising a spherical thickening 14 at that point. This thickening constitutes part of a branch piece 15 (see Fig. 4) which is screwed to the lower end of the rod-shaped unit 4. This branch piece 15 consecutively compriscs a nut-shaped end 16, a groove or a narrow zone 17 (also referred to as "a neck portion") and a spherical portion 18. The sleeve 8 may easily ~e slid upward so as to release the circular element, while during the mounting of the suspension bow, a downward movement of the sleeve 8 rcsults in a certain enclosure with the tongues 7, the recess 13 of which is kept in contoct with the spherical thickening 14.
the all-sided pivotal coupling 9 is composed of two parts comprising a stud 19 and a cap nut 20 movably coupled therewith, this cap nut being j .

It will be clear that the suspension bow 1 is composed of a number of parts which, in mounted posi-tion, allow a certain movement by means of which the elevational adjustment of the circular element 6 may `
be obtained, The stud 19 may be fastened more or less far in the supporting structure 2, while the rod-shaped unit 4 may be screwed more or less far into the cap nut 20. The clearance between the sleeve 8 and the nut-.~haped portion 16 of the branch piece 15, in com-bination with the coupling 9, provides a certain displaceability (see Fig. 2). Moreover, a provisional support of the pipe 3 during the mounting of the suppor-ting structure now has become superfluous.

The pivotal coupling 10 has been obtained in that near their cnds, the tongues 7 comprise a recess 13 being directed toward the rod-shaped unit 4, said unit comprising a spherical thickening 14 at that point. This thickening constitutes part of a branch piece 15 (see Fig. 4) which is screwed to the lower end of the rod-shaped unit 4.
