Definitions
- the present invention refers to certain interesting improvements made to joining devices of the type used for creating load-bearing systems for workstations, particularly but not exclusively for offices.
- the structure created should be as solid and stable as possible over time, without risks of deterioration due to the materials used.
- the general purpose of the present invention is to propose a joining device for making load-bearing systems for workstations that adequately meets all the requirements listed above, with particular reference to the flexibility of use, the production costs, which must be very contained, and the absolute rigidity over time of the structure obtained, also in the presence of relatively demanding stresses.
- a joining device is indicated, as a whole, by 20, and is structurally made up of a body 21 from which at least one attachment 22 extends.
- the body 21 and attachments 22 can be made of a single piece, for example of metal or plastic material having the necessary physical and mechanical characteristics for the purpose of the device.
- each individual attachment 22 is made a seat 24 for a beam 25 which has the function of ensuring stable and durable fixing over time between a tubular section 23 and the attachment 22 itself.
- Said beam 25 for example a metal beam and one having a preferably double-T-section is housed in its seat 24 so as to be movable (parallel to itself) between the lowered, non-operative, position of Figures 3, 6 and 8 and the raised, operative, position of Figures 5, 7 and 9.
- Displacement of the beam 25 with respect to the complementary seat 24 is performed by means of a threaded headless adjustment screw 26, which is screwed through a corresponding threaded hole 27 made centrally in the beam 25 itself.
- the headless screw 26 is provided with a discoidal base 28 housed in a corresponding cavity 29 ( Figures 3 to 5) located on the bottom of the seat 24.
- Said cavity 29 is moreover preferably provided with a perimetral edge 30 for retention of the base 28, which snap-fits into the cavity 29 itself.
- the adjustment of the headless screw 26 is performed using a polygonal spanner (not shown) which is inserted into a complementary seat 31 of the headless screw 26.
- Access to the headless screw 26 is via an aligned hole 32 made in the tubular section 23.
- the body 21 is preferably made in such a way as to enable fitting thereof to a tubular leg 33.
- the fitting systems between the body 21 and the leg 33 may be of various kinds.
- a nut 34 may be used, which is screwed directly on a threaded shaft 35 extending centrally from a disk 36 fixed to the leg 33 ( Figures 11 and 12); or else, a bolt 37 may be used which screws through a threaded hole 38 of a disk 39 fixed to the leg 33 ( Figures 13 and 14).
- a tubular section 23 having a cross section complementary to that of the corresponding attachment 22 is fitted on the latter with the beam 25 in the position where it is retracted inside its complementary seat 24, as shown in Figures 3, 6 and 8 of the drawings.
- the headless screw 26 can be turned so as to load the beam 25, so that it is translated upwards in the direction of the arrow 41 ( Figures 6 and 8).
- the external flanges of the beam 25 engage on the inner surface 42 of the tubular section 23, so as to load, in the direction of the arrows 43 and 44, the attachment 22 so that it engages stably with the tubular section 23 at a large common perimetral surface 45, which occupies almost the entire cross section of the two assembled components 22, 23, except for the area where the beam 25 - adjusted by the headless screw 26 - exerts its thrust.
- the tubular section 23 may be separated from the attachment 22 by unscrewing the-headless screw 26 so as to bring the beam 25 back into the lowered position of Figures 3, 6 and 8. It should be noted that in this position the beam 25 bears upon the base 28 of the headless screw 26, thus determining a stable positioning (end of travel) of the latter completely within the seat 24. In this way, the tubular section 23 may be freely slid off the attachment 22, given that any interference of the headless screw 26 in the path of the tubular section 23 is certainly excluded.
- a stable fixing is thus achieved even over time, which, however, can be released by simply unscrewing the headless screw 26 and then bringing the beam 25 back into the original position shown in Figures 3, 6 and 8.
