Definitions
- hing devices including a male element of hollow construction to lighten the structure and decrease its manufacturing costs.
- the hollow structure of the male element may develop another problem associated with the surface treatment thereof: when immersed in galvanic baths, some of the liquid seeps into the interior of the male element and is trapped therein as the element is advanced to the next treatment bath, thereby contaminating successive tanks, with small quantities of different liquids from prior baths, the passage whereof is necessary to complete the treatment.
- any liquid left inside the hollow male element could flow out of it and corrode, by its mainly acid nature, other hinges.
- Another important object is to provide a hinge device which combines with the preceding feature a reduction in the overall manufacturing costs, and in particular a significant reduction in the quantity of material employed.
- a further object of the invention is to provide a hinge device which reduces contamination of successive galvanic baths during the treatment thereof.
- a not unimportant object is to provide a hinge device which can be manufactured by utilizing standard equipment, and readily available materials which is safe and reliable in use.
- a hinge device characterised in that it comprises a hollow male element having a pin on the end of which a seat is formed for a sphere made fast with said seat, said hinge further comprising a female element, matingy shaped to match the pin, a means being provided for associating the hinge device with casings.
- the hinge device 1 comprises a male element 2 and a female element 3.
- the male element 2 includes a cylindrical body 4 and a cylindrical pin 5, of similar shape and having the same longitudinal axis but defining a smaller diameter than the body 4.
- the male element 2 defines between the pin 5 and the body 4 an annular flat base 6, extending perpendicularly to the longitudinal axis of the male element 2 and having a radial extension corresponding to the difference between the diameter of the cylindrical body 4 and the diameter of the pin 5.
- Both the body 4 and the pin 5 define hollow intemal cavities, 7 and 7a respectively, the size of the cavity 7 being larger than the latter 7a.
- a cylindrical seat 9 having a slightly larger diameter than the cavity 7, and adapted to accommodate a spherical bearing consisting of a small hardened sphere 10.
- the seat 9 extends along the longitudinal axis of the cavity 7a for a distance which is greater than the radius of said sphere 10 but smaller than the diameter thereof.
- the hardened sphere 10 has a slightly smaller diameter than said seat 9 and is made fast with the pin 5 by upsetting its end 8; this prevents the sphere 10 from coming out of the seat 9 as well as preventing liquid from entering the cavities 7, 7a through the end 8 of the pin 5 during the phase of immersion in galvanic baths.
- the sphere 10 thus becomes the terminating extremity of the pin 5.
- the female element 3 has a cylindrical body 11 matin- gly shaped to receive the pin 5 of the male element 4, in a seat 12 having an end 12a and defining an axial extension which is slightly smaller than the length dimension of the pin 5, with the sphere 10 located in the seat 9.
- the end 12a of the seat 12 defined by the female element 3 rests and is rotatable on the sphere 10 with neglectable friction, due to the small surface area of tangential contact between the curved surface of the sphere 10 and the flat surface of the end 12a.
- a means 15 for associating the hinge 1 with casings said means comprising, for example, a threaded shank 16.
- the hinge 1 owing to the configuration of the pin 5 and seat 12, advantageously works on the sphere 10 and not on the annular base 6: this improves the functional aspect since the coefficient of friction existing between the respectively rotatable elements 2,3 of the hinge is greatly reduced, and the point of rotation is protected inside the female element 3.
- the male element 2 being hollow, lowers the production costs by reducing the quantity of raw material employed in the manufacture of the hinge device.
- the sphere 10, by closing the cavity 7, 7a also prevents the liquid present in the galvanic treatment tanks from entering the male element 2, and being inadvertently transported to, and thereby contaminating, successive tanks containing different liquids.
- the hinge device according to the invention achieves all of the objects set forth, which allows manufacturing costs to be reduced, and simultaneously provides an improved hinge device from the functional point of view.
