Description

- DESCRIPTION -

  A system for connecting a metal target to a vertical post or similar support member at an angle other than 900, while a threaded end with a threaded connection stud is attached to the cable. that the end piece can be driven through an oblique hole in the post or the like, that on the free end of the threaded stud projecting from the post or the like is inserted an adapter provided with a

  bearing surface adapted to the post or the like and of a sup-

  front face directed perpendicular to the threaded stud,

  and that a nut can be screwed onto the threaded stud by

  puyant on the perpendicular front surface and maintaining

  resting the bearing surface against the lateral surface

post or the like.

  Systems of this kind are known from the state of the art. As regards the adapter, it is a tubular element which is perpendicular to the stud bolt on one of its end surfaces and which is oblique in

  various angular positions on its other surface.

  this frontal. According to whether it is a post or a support member which has a flat bearing surface or whose contact surface is rounded, as for example in the case of a circular cross section post , the corresponding support surface of the adapter is not only

  oblique according to the angular position of the metal cable-

  or similar to the post, but it can be

  also dug a groove adapted to the shape of the pole.

  In a system and conformation of this kind, it

  it is necessary to provide a different adapter each time.

  for different angles, a staggering of the over-

  oblique face of five degrees in five degrees being common in

  the state of the art. This entails extreme expenditure

  important storage and manufacturing

  adapters each for angular positions.

  different for the oblique departure of tensioning

  similar from stair railing or similar

  lar. From this state of the art, the object of the invention is to create a system of the kind specified at the beginning which allows to connect metal cables to poles in different angular positions with significantly lower expenses for storage and for

the making.

  To achieve this goal, it is proposed that adapting

  at its end facing the side surface

  of the post or the like, an oblique surface which extends directed at the front surface at an angle other than 0 and 90, and preferably at an acute angle, that the underside of the oblique surface is hollowed out in the form of a spherical cap, and between the oblique surface and a corresponding bearing surface of a post or the like is disposed a pierced washer whose bore is larger than the threaded stud of the tip and that the

  passage of the adapter, preferably being equal to

  of the latter, while the surface of the washer which is turned towards the adapter is previously curved in the form of a sphere in a manner similar to the spherical cap shape of the oblique surface, and that its surface which is turned towards the bearing surface is hollowed into a sphere in the same way, so that the washer can be depressed on

  the adapter with the threaded end in angular positions

different res.

  In a known manner, it is preferably provided that the threaded end has flats which are intended for

the coming into play of a key.

  Thanks to the fact that the support surface of the adapter

  is shaped like a spherical cap or

  similar, and thanks to the presence of the additional puck

  which is previously bent or hollowed, respectively

  on its two frontal surfaces in the manner of a similar spherical cap, it is possible to

  different starting angles by means of one and the same

  including the washer, as the adapter may be

  moved in relation to the puck because of the spherical shape

  that and take different angular positions. Due to the relatively large drilling of the washer, the displacement

  threaded end to different angular positions.

  annuities is not embarrassed. It adds that, because the washer is also hollowed on its surface facing the pole, a free space is made available for the displacement of the threaded end when the latter is moved with the adapter relative to the puck into

different angular positions.

  Thanks to this system and this configuration, storage costs are considerably reduced, since many different angular positions can be obtained at the same time.

  a single adapter and the associated washer

  OETC. According to whether the post or the corresponding support member has a flat bearing surface, as for example in the case of a square or rectangular cross section tube, or that the post or the like has a section

  circular cross-section, we can give a conformation cor-

  corresponding to the washer which, in the case of round or similar posts, must be hollowed out or bent accordingly, transversely to its central axis, depending

  the rounding of the post or the like.

  Preferably, all elements of the system are made of special steel. The flats which are provided on the threaded end serve to engage a tool which may be a flat key, so that when a corresponding nut is screwed onto the threaded stud, the threaded end may be held by means of the flat key being prevented from turning. An exemplary embodiment is shown in the drawing, and is hereinafter described in more detail. The figures show: Figure 1 a washer shown in different elevational views; Figure 2 a corresponding adapter shown in different elevational views; and:

  Figure 3 the system mounted on a vertical pole

  cal. As can be seen in particular in Figure 3, the

  system for connecting a wire rope 1 to a vertical pole

  14 at an angle that is different from 90 'is achieved thanks to the fact that a threaded end 2 provided with a threaded stud

  3 is attached to the wire rope 1 in a manner

  re usual, while the threaded end 2 passes through its threaded stud 3 corresponding oblique holes 4 of the pole 14. On the free end of the threaded stud 3 which is opposite the cable and which projects out of the pole 14 is pressed a adapter 5 provided with a suitable support surface

  to the post 14 and a front surface 6 directed perpendicularly

  the threaded stud 3, a nut 7 can be screwed onto the threaded stud 3. In the desired position, the nut 7 rests on the front surface 6 which is perpendicular to the

  threaded stud, while the support surface of the adapter

5 is supported on the pole 14.

  According to the invention, the adapter 5 is provided at its end facing the lateral surface of the post 14 with an oblique surface 8, the latter extending while being directed by

  compared to the front surface 6 at an angle that is different

  from 0 to 90. Preferably, the arrangement forms

  about an acute angle. The lower side of the surface

  8 is here hollowed out in the form of a spherical cap. The spherical cap shape 9 is particularly visible on the

representation according to Figure 3.

  Between these spherical surfaces 8 and 9, respectively,

  and the corresponding bearing surface of the post 14 is disposed a pierced washer 10, the piercing 11 of which

  a diameter which is about twice that corresponding to

  The surface of the washer 10 which is turned towards the adapter 5 is previously bent in the shape of a sphere in a similar manner to the shape of the adapter 5. spherical cap 9 of the oblique surface 8. The surface of the washer 10 which is turned towards the bearing surface of the post 14 is hollowed out in the form of a sphere in the same manner, so that a free space occurs between the post 14 and the puck 10, as

  it can be seen in particular in FIG.

  In the vicinity of the extension of the threaded stud,

  the threaded end 2 also has flats 13 which serve

  wind & the coming into engagement of a flat key or the like.

  As can be deduced in particular from the

  re 3, the relative angular position of the threaded end 2

  can be set differently. Figure 3 shows a posi-

  extreme situation. However, other angular positions can be made in which the threaded end has substantially rotated counterclockwise in Figure 3 of the drawing. Of course, it is then necessary to provide holes 4 which are adapted to the corresponding post 14. A different oblique position must be adjusted according to the angular position of the threaded end 2, the conformation

  according to the invention making it possible to obtain a plurality of posi-

  angular differences by means of one and the same system

tem.
