Articulated junction device
View Patent ↗An articulated junction device between a suspended structure and a load bearing structure comprises a hinge pin, at least one first part being installed in the suspended structure so as to be able to rotate about a first axis and a second part installed in the load bearing structure so as to be able to rotate about a second axis. The hinge pin passes through the first part and the second part. The first axis and the second axis are parallel to each other and offset from each other.
1. An assembly comprising:
a load bearing structure having a first circular member rotatable about a first axis along a first horizontal axis, the first circular member having a first aperture;
a suspended structure having a second circular member rotatable about a second axis along a second horizontal axis, the second circular member having a second aperture, the suspended structure including two plates parallel to each other and configured to receive the load bearing structure therebetween, wherein each of the two plates of the suspended structure cooperate with the load bearing structure through spherical surfaces together defining a ball joint connection therebetween; and
a coupling member received in said first and second apertures to couple the suspended structure to the load bearing structure with the first axis adjacent to the second axis, the coupling member being oriented along a third axis parallel and adjacent to the first axis and the second axis, wherein the first and second circular members are unable to rotate with respect to one another about the third axis via a rotation prevention means and the second axis is offset vertically upwards from the first axis.
2. An assembly comprising:
a load bearing structure having a first circular member rotatable about a horizontally oriented first axis, the first circular member having a first aperture;
a suspended structure comprising two plates parallel to each other between which the load bearing structure is placed, each of the two plates of the suspended structure having a second circular member rotatable about a common horizontally oriented second axis, and each of the second circular members having a second aperture;
a coupling member received in said first and second apertures to couple the suspended structure to the load bearing structure with the first axis adjacent to the second axis, the coupling member being oriented along a third axis parallel and adjacent to the first axis and the second axis, wherein the first and second circular members are unable to rotate with respect to one another about the third axis and the second axis is offset vertically upwards from the first axis;
rotation prevention means provided between the coupling member and each of the first and second circular members, said rotation prevention means being configured to prevent any relative rotation therebetween; and
intermediate parts forming ball joint cages fixed in each of the two plates of the suspended structure, second spherical surfaces being formed between the ball joint cages and the second circular members.
3. An assembly comprising:
a load bearing structure having a first circular member rotatable about a horizontally oriented first axis, the first circular member having a first aperture;
a suspended structure comprising two plates parallel to each other between which the load bearing structure is placed, each of the two plates of the suspended structure having a second circular member rotatable about a common horizontally oriented second axis, and each of the second circular members having a second aperture;
a coupling member received in said first and second apertures to couple the suspended structure to the load bearing structure with the first axis adjacent to the second axis, the coupling member being oriented along a third axis parallel and adjacent to the first axis and the second axis, wherein the first and second circular members are unable to rotate with respect to one another about the third axis and the second axis is offset vertically upwards from the first axis; and
rotation prevention means provided between the coupling member and each of the first and second circular members, said rotation prevention means being configured to prevent any relative rotation therebetween, wherein first spherical surfaces are formed between the load bearing structure and the first circular member, said first spherical surfaces defining a first ball joint connection between the load bearing structure and the complying member, and second spherical surfaces are formed between the second circular members and the two plates of the suspended structure, said second spherical surfaces defining a second ball joint connection between the suspended structure and the complying member.
