Definitions
- Hinge mechanism for glasses with axial rotation, automatic return and extra- opening of the rod
- the present invention relates to a hinge mechanism for glasses wilh rods which open wide in an elastic way, of the type comprising a first element integral wilh a glass frame and a second element rotating together with an end of a rod.
- Glasses provided with similar hinges are substantially different from the usual glasses of the prior arl because they allow the rods to be elastically opened wide beyond the usual opening position (the angle between the rod and the frame is about of 90 degrees) so permitting the user to easily wear them; the axial rotation of the rods allows the glasses to belter fit to Ihe user.
- Glasses of this type are usually made for example by means of an helicoidal spring having a first spiral-shaped end hinged to the first hinge element of the frame, by usual fixing means such as a peg, and a second end connected to the rod by otiier fixing means. Tlie end of the rod is hollow and suitably shaped in order to contain the spring and the fixing means. When the rod is opened wide beyond the usual opening position, the end of the rod connected to the second end of the spring moves away from the first hinge element stretching the spring which causes the rod to elastically return to the usual closing position.
- Suitable constraint means is provided for stiffening the structure so avoiding the rod to accomplish movements different from the simple rotation around the first hinge element and for only stretching the spring, said constraint means are for example telescopic structures or elements and /or slots which longitudinally slide inside each olher.
- the aim of the present invention is to produce a hinge mechanism for glasses with rods which open wide in an elastic way eliminating the drawbacks cited with reference to the prior art.
- a hinge of the type comprising a (list element integral wilh a glasses frame and a second element rotating logcthcr with an end of a rod, characterised in the fact that said second hinge element comprises a pin having two opposite ends, a first end hinged to said first hinge clement and a second free end, an element sliding along said pin and furthermore elastic means positioned between said sliding element and the free end of the pin.
- a first part of said sliding element abuts on the first hinge element when (he rod is in the usual opening position and increasingly presses on the first hinge element when the rod is opened wide beyond ils usual opening position so that said sliding clement moves towards the second free end of the pin and slides along the pin, so as to compress said elastic means, which causes the rod to return to (he usual opening position.
- an element rotating wilh respect to the pin is mounted on the second free end of said pin, said rotating element being longitudinally fixed lo said pin and rotationally moving together with said rod, and said sliding element is rotationally fixed to said pin and said elastic means has two opposite ends, a first end of which is attached to said sliding element and a second end is attached lo said rotating element, so thai rotating the rod around the axis of the pin, starting from the usual position of the rod, said elastic means is torsionally stressed so to cause the rod lo return to the usual position.
- a second part of said sliding element abuts on the first hinge element when the rod is in the usual opening position and increasingly presses on the first hinge element when the rod is moved from the usual opening position towards an intermediate closing position, so thai said sliding element moves towards the second free end of the pin and slides along the pin, so as to compress said elastic means which causes the rod to return lo the usual opening position, and furthermore, characterised in that said second part of the sliding element presses, in a decreasing way, on the first hinge element when the rod is moved from the intermediate closing position towards a complete closing position, so that said sliding element moves away from the second free end of the pin and slides along the pin thanks to said elastic means, which causes the rod to elastically return to the complete closing posilion.
- the rod end is hollow and designed to contain inside said second hinge element so as lo obtain a pleasant aesthetic effect also avoiding the entry of dust or olher impurity hindering the correct operating of the hinge and also preventing hair entangle into (he hinge.
- FIG. 1 is a schematic view of a part of a glasses frame comp ⁇ sing a hinge according lo (he present invention
- figure 2 is an enlarged view ofthe particular enclosed within the circle of figure 1 ;
- FIG. 3,4 and 5 are longitudinal views of figure 2 wherein the rod is respectively represented in the usual closing position, in the usual opening position and opened wide beyond the usual opening position;
- -figures 6,7 and 8 are views of the hinge pin viewed along three directions perpendicular each other;
- FIG. 1 1 and 12 are respectively the front and plant views of a spacer
- FIG. 13 is views or the element sliding along the pin viewed along three direction orthogonal each olher;
- FIG. 16 is a front view section of the rod end
- -figures 19, 20 and 21 are views of a nut screwed into a pin end viewed along three directions perpendicular each olher.
- FIG I is represented a rod 10 hinged lo a glasses frame by a hinge 12. More in particular, from figures 2,3,4 and 5 it can be seen that Ihe hinge 12 comprises a first hinge element 14 fixed to the frame and a second hinge element 16 which rotates together w ith the end 10a of the rod 10.
- the first hinge element 14 has two prongs 14a and 14b respectively provided with holes 15a and 15b having aligned axes.
- the second hinge element 16 comprises a pin 20 (in particular sec figures 6 and 7) having opposite ends 20a and 20b; the end 20a is sphere-shaped with two fiat walls. has a centre hole 20a and is positioned between the two prongs 14a and 14b in such a way to align the holes 15a and 15b with the hole 20a into which a screw 02 (see figure 2) is screwed, whereas the end 20b is threaded and an hexagonal nut 28 (see figure 3) is screwed into the end 20b.
- the second hinge element 16 comprises also a sliding spoon-shaped element 24 (see figures 13.14 and 15) the inside of which is hollow and square into which slides a part of the pin 20 of the same square section (see figure 9) placed near the end 20a so that the sliding clement 24 is rotationally fixed to the pin 20.
- the second hinge element 16 comprises also a spring 26 placed between the sliding element 24 and the nut 28 .
- the spring 26 has two opposite ends 26a and 26b: the end 26a is inserted into a hole 27 made in the sliding element 24 whereas the end
- 26b is inserted inside a hole 30 made in nut 28 (sec figure 20).
- the pin 20. die nut 28 and the spring 26 arc contained inside a cavity 32 made in the end 10a of the rod 10 (sec figure 6).
- Ihe cavity is cylindrical for almost ils length (sec figure 17) and is designed to contain also a cylindrical part 34
- the sliding element 24 has, in addition to the cylindrical part 24, also a spoon-shaped projection 22 which abuts on a shoulder 38 (sec figure 3 ) made on (he first hinge element 14 when (he rod 10 is in the usual opening position as indicated in figure 4. Starting from this position, if the rod is further opened, as indicated in figure 5, the sliding element 24 presses on the shoulder 38 w hereby it is compelled to move away from the first hinge element 14 and slides along the pin 20 so lo approach Ihe nut 28 acting against the spring 26 which is compressed. If the rod is released, thanks to the elastic force of the spring 26, the rod reaches (he original opening position.
- ⁇ tube-like spacer (see figures 1 1 and 12) is positioned between the sliding element 24 and the nut 28 (sec figure 4 ) and inserted between the pin 20 and the spring 26 to limit the extra-opening of the rod 10, the spacer being slightly shorter than the distance between the sliding element 24 and the nut 28 when the rod 10 is in the usual opening position; when the rod 10 is opened wide at the maximum possible extent, the sliding clement 24 is moved towards the nut 28 and the two ends of the spacer 44 comes into contact with the sliding element 24 and the nut 28, so preventing a further opening of the rod 10.
- the sliding clement 24 has a flat surface 39 (see figure 15) whereas the first hinge element 14. and in particular the prongs 14a and 14b, has an right-angle contour formed by (wo sides 40 and 42. Closing the rod, the fiat surface 39 slides along the right-angle contour of the first hinge element 14 which functions like a cam and, more precisely, starting from the position where (he rod is in the usual opening position ( figure 4 ), wherein the flat surface 39 of the sliding element 24 abuts against the side 40 of the right-angled contour of the first hinge clement, until the rod is moved lo the usual closing position (figure 3) in which the fiat surface 39 of
- Consequendy il can be seen that if the rod 10, starting from the usual opening position ( figure 4 ), is moved towards a closing position, the sliding element 24 is compelled to move away from the first hinge element 14 sliding along the pin 20 towards the nut 28 I hc spring 26 is compressed whereby if the rod 10 is released, it returns to Ihe usual opening position.
- the rod 10 may rotate around its axis torsionally stressing the spring 26 because the rotation of the rod causes the nut 28 to rotate and the end 26b of the spring 26 is attached to the nut 28, whereas, the other end 26a is attached to the sliding clement 24 which cannot rotate. Then, if the rod is released, it returns to the original position.
- ⁇ circumferential slot 46 (sec figures 2 and 16) is made on the free end of the cylindrical cavity 32 of the rod 10 in order to limit the rotation of the rod around its axis w hereas a hole 48 (see figure 13 and 15) is made in the cylindrical part 34 of (he sliding element 24 so that, after having inserted the rod 10, a screw 30 (figure 2) is screwed in the hole 48 thanks to the slot 46 so that the screw head may slide inside Ihe slot 46 when the rod 10 is rotated around its axis.
- a screw 30 (figure 2) is screwed in the hole 48 thanks to the slot 46 so that the screw head may slide inside Ihe slot 46 when the rod 10 is rotated around its axis.
- the rod 10 is in the usual position, (he spring 26 is slightly and torsionally stressed compelling Ihe head of the screw 30 lo abuts against an end of the slot 46.
- briell ⁇ consists of a pair of glasses with rods which open wide in an clastic way which aie simple and strong.
- I he frame is very flexible because has two equilibrium positions, one of Ihe usual opening and the other of complete closing and allow s also Ihe rod lo elastically rotate so as lo permit the same lo fit lo the user.
- the hinge may be easily mounted on any type of frame being sufficient lo suitably adapt the sliding element to the first hinge element of the frame.
