Definitions

  • This invention relates to a substantially spherical knuckle for a spacial structure, the knuckle being formed by two mating hollow base pieces which are joined together by connecting means and which are each provided with a plurality of holes for the attachment of one or more sections of the spacial structure.
  • the holes in each mating base piece are equidistantly positioned with respectto one another at a predetermined angular distance.
  • US-A-4 027 449 shows a substantially spherical knuckle of this construction.
  • a disadvantage however of the knuckle shown in that prior Patent is that the two mating hollow base pieces have outwardly-extending flanges which seriously inhibit the range of positions to be taken by connecting sections forming part of the spacial structure.
  • One aim of the present invention therefore is to provide a substantially spherical knuckle which avoids this particular disadvantage.
  • a substantially spherical knuckle is also known from EP-A-0 081 608.
  • the knuckle does not have connecting means at the joining area between the two mating base pieces. This leads to structural weakness in the knuckle so that it is a further aim of the present invention to produce a substantially spherical knuckle which avoids this disadvantage as well.
  • the present invention is directed to a substantially spherical knuckle of the construction outlined in the opening paragraph of this specification wherein one of the hollow base pieces is formed with an inwardly-bent perimeter lip while the other hollow base piece is formed with an outwardly-bent perimeter lip which faces and externally engages the lip so as to form a joining area-where the connecting means are located-between the two base pieces.
  • a knuckle of this construction avoids the two disadvantages mentioned above in connection with the prior art and therefore provides an improved form of spherical knuckle.
  • the knuckle is comprised of two base pieces 1 and 2.
  • base piece 1 is larger than base piece 2, giving an asymmetrical joint, but is is perfectly feasible for both pieces to be practically alike.
  • the outside shape of the two base pieces is that of a spherical shell in order that its external form in the coupling is approximately a sphere.
  • Holes 3 provided upon each of the spherical shells are equidistantly positioned with respect to one another; and there is an angle ⁇ between the adjoining edges of the different spherical shells when they lie together. (See Figure 3). These holes 3 form part of the joint between the spacial knuckle and sections 6. The angle ⁇ can be altered for each knuckle and each different structure.
  • the first base piece 1 has a perimeter area 12 which is bent upon itself and is provided with open holes 13 which are preferably threaded.
  • the holes 13 form part of the joint between the two base pieces 1 and 2.
  • the other base piece 2 has, in turn, a lip 21 into which engages the lip 12 provided on base piece 1.
  • the lip 21 is shown as engaging externally with lip 12, but the invention also includes the idea where lip 21 is given a similar shape to lip 12 so that the two can engage together by means of protrusions like those depicted in Figure 4.
  • Base piece 2 is provided with slots 21 bis which facilitate the engagement and joining with sections 6.
  • Base piece 2 is furthermore provided, opposite the holes 13 on base piece 1, with open holes 13 bis, and joining screw 5 is housed in said holes 13 and 13 bis.
  • Base piece 2 is moreover provided with protrusions 30 which engage in siots 31 arranged in base piece 1 (See Figure 4), although it is more logical to think of the reverse construction.
  • a strengthening member 7 which may be a tubular section one of whose ends abuts against the inside of poles 11 and 22.
  • a stud 71 is provided inside said tube 7 whose head 23 abuts against pole 22 and, by means of nut 4, it abuts under pressure against pole 11, thus helping to secure base pieces 1 and 2 against one another.
  • Figure 5 shows a single-piece element 16 in revolution which is weld-attached at 15 to tubular section 6.
  • Said single-piece element 16 has a conical frustrum side surface in order for it to suit different diameters of tube 6.
  • the tightening screw 20 has a head 8 which, either directly or by means of a widened area 9 or an additional member such as a washer having the same shape, is offered to the inside surface of base piece 1,2.
  • the contact face of the widened area 9 is spherical so as to facilitate contact.
  • the single-piece element 16 has a face 10 which is offered to the outside face of the same base piece 1, 2, and said contact face is spherical as well for the reasons given.
  • Screw 20 and single-piece element 16 are threaded together in engagement, thus accomplishing the joint between tubular section 6 and base piece 1, 2.
  • the design can also be such that the side surface 14' adjacent to the joining face 10 is shaped as a conical frustrum, thus preventing said contact face 10 from needing to be excessively large.
  • the joining means comprised (a) of the strength member 8 with its stud 71 and fittings, and (b) of screw 5 in the engagement area, can be used either individually or together, and the presence of protrusions 30 is always optional.
