Definitions

• the door Once the door is released, it recloses and the force of the spring is unloaded. In this return movement to the starting phase, as the spring has been loaded to the maximum of its opening possibilities, the door acquires a considerable accelerating speed and slams with great violence.
• the spring must exceed not only the weight of the door to be reclosed, but also the friction caused by the spring-holder pin with its hinging seat.
• the springs must in any case be capable of bring the door panel back into a closed position, when released by the user.
• a general objective of the present invention is to overcome the drawbacks of the known art mentioned above in an extremely simple, economical and particularly functional manner.
• a further objective is to provide a hinge with a force regulator for fireproof doors which prevents a violent return to a closed position due to the loading of the spring, under both closing and opening conditions .
• Yet another objective is to provide an improved hinge for fireproof doors in which it is actually possible to regulate the closing movement by delaying or accelerating the door.
• a hinge with a force regulator for, fireproof doors has been : conceived, having the characteristics specified in the enclosed claims. i .
• the structural and functional characteristics of the ⁇ resent invention and its advantages with respect to the known art will appear even more evident from the following description, referring to the enclosed drawings, which, among other things, show a schematization of an embodiment ' of a hinge for fireproof doors produced according to the same invention.
• the drawings show a schematization of an embodiment ' of a hinge for fireproof doors produced according to the same invention.
• figure 1 shows a schematic and synthetic view of a fireproof door equipped with a hinge according to the present invention
• figure 2 shows a partially sectional plan view of the hinge according to the invention in an open position with the spring loaded
• figure 3 is a view from above of the hinge as shown in figure 2 according to the arrow F;
• figure 6 is a view of details shown in figure 4 assembled in the two component parts
• FIG. 7 shows a plan view from above of the cam block which allows a contrary force for the closing and slow-down of the door panel in a rotation for passing from an open door panel to a completely closed door panel;
• FIG. 8 shows a raised view of the upper part of the block shown in figures 5 and 7.
• this illustrates a schematic view which shows a fireproof door in which a real panel or door 14 is assembled on a wall 12 inside a frame 13 or stile.
• a hinge for example the upper hinge, is produced according to the present invention and is indicated as a whole with 11.
• the upper hinge 11 is associated with a lower hinge 10 which automatically closes the panel of the fireproof door 14 by means of a known torsion spring which is not shown in the figures.
• Said torsion spring is almost unloaded when the door panel is closed according to a rotation angle of 0° with respect to the frame 13 and is completely loaded in the maximum opening position when it reaches a rotation angle of 180° with the door panel completely open (maximum operative loading of the return spring) .
• said lower hinge 10 allows the panel 14 to reclose by activating the return torsion spring for its whole return run from 180° to 0°.
• the upper hinge 11 comprises a frame-side portion 15 and a door-side portion 16, both made of a thick 5 metal sheet, for example in galvanized steel or another suitable metallic material.
• connection zone 19 is envisaged between the fixing plate 17 and tubular sections 18.
• Said force- I regulator and supporting hinging group comprises, as in the housing sequence in the tubular sections 18 and 21, [25 a supporting group and a force regulator group with an adjustable force in relation to the specific requirement .
• the supporting group comprises a cylindrically shaped sleeve or bucket 23, blocked in a first tubular section 18 by means of a bead 67 screwed into a respective threaded hole 68 situated in the tubular section 18.
• the bead 67 has a faceted cylindrical tip with six supporting surfaces on one of three sloping slots 69 (when not rotating, it is therefore unlosable with vibrations) .
• a bearing arrangement housed therein is thus created.
• This arrangement allows the adjustment of the position of the bucket 23 inside the tubular section 18 and consequently the regulated positioning of the bearing arrangement housed therein, in addition to a regulation on the vertical axis.
• a second groove 30, facing the first groove, 27, is in fact situated on ai short cylindrical body 31, which is inserted blocked in the tubular section 211 of the door-side portion 16 of the hinge.
• the groove 30 of the cylindrical body 31, the withholding cage 29 of the balls 28 and the groove 27 of the bucket 23 form an axially supporting bearing in the hinge positioned between the frame-side portion 15 and door-side portion 16 of the hinge.
• a cam force regulator group for the rotation of the hinge acting for a certain rotation angle starting from the completely open position at 180° of the door, is envisaged, aligned with the small cylindrical body 31.
• the cam force regulator group i for the rotation of the hinge comprises a cam block 50, also cylindrical, in which a pass-through threaded hole 51 is axially situated and a further threaded hole 52 positioned radially which intersects with the hole 51.
• the surface of the cam block 50 opposite that facing the small cylindrical body 31 comprises a cam surface divided into two symmetrical halves which forms a double half -groove 53 for the sliding of the two balls 54, which culminates with apexes 55.
• the presence of the balls 54 facilitates the sliding between the ; parts thanks to the rolling friction.
• the balls 54 are arranged in housings 56 situated in a further ball-holder body 57, also cylindrical and hollow, aligned with the others and at least partly contained in the second tubular section 18 of the frame-side portion 15.
• said housings 56 can pass into a wall 58 and are kept in position by the base of the spring or by a further stop washer (not shown) such as that indicated hereunder with 62.
• the screw 60 preferably with an embedded hexagonal head, is housed inside the ball-holder body 57 in the hole 59,: after receiving a spring 61 and a head stop washer 62 of the spring 61 at the embedded hexagonal head of the screw 60.
• the cam block 50 and balls 54 of the ball -holder body 57 are therefore kept engaged by the compression spring 61 and by the screw 60 whose position can be regulated, which forms the elastic force regulation means .
• a bead 63 inserted through a radial threaded hole 64' situated in the tubular section 18 of the frame- side portion 15, is then inserted in a hole 64 of the hollow ball -holder body 57 blocking the latter with respect to the tubular section 18 of the frame-side portion 15.
• a double action is actuated.
• the movable part of the hinge including the block 50, follows a rotation angle a, for example a rotation angle of about 100°.
• the cam block 50 brings its apexes 55 into engagement with the balls 54 that are moving upwards on the slope of the groove 53 along the angle a.
• a second descent phase is initiated for an angle: ⁇ , for example of about 80° passing from 100° to 180°, and the door panel 14 springs to a complete opening, trying to remain blocked thereby (on the left in figure 7) .
• Figure 7 shows a plan view from above of the development of the two half-grooves 53 which collaborate with the balls 54 exerting the same double function that extends from 0° to 180° to pass from a closed position of the door panel to a completely open position.
• the cam block 50 rotates by 180° in a clockwise direction.
• Figure 7 also shows how, in a closed : phase of the door panel 14 for the first angle ⁇ of the 180°, the rising slope towards the apex 55 slows down the panel thanks to the presence of the spring 61. Once the apex 55 has been reached, the presence of the descending slope ensures that the force of the spring 61 is added to the residual return force of the torsion spring of the second hinge 10 for the remaining second angle a of the 180°.
• the hinge according to the invention therefore creates a force regulating mechanism which determines the closing velocity of the door.
• This hinge allows the closing velocity of the door to be controlled, in particular heavy fireproof doors, which are closed with a torsion spring.
• a hinge according to the present invention therefore adjustably dampens the return closing force of the door and at the same time advantageously carries the weight of the door per se, thanks to the particular arrangement of the bearing and relative assembly parts of the same .
