Abstract
Description
- The present invention concerns an adjustable counterbalancing system, specially suitable for hinges with horizontal axis, used as articulation of the door and body of a household electric appliance.
- Generally speaking, the present system is fitted for all auto-balancing hinges that counterbalance during opening and closing operations of the door.
- The system is equipped with a mechanism that moves in relation with the hinge movement, connected with an elastic extendible member, stressed so that its elastic reaction varies in accordance with the door position and balances the torque produced by the door weight.
- More particular, but not exclusively, the object of the present invention is a counterbalancing system of the above described type, applied to a particular hinge, such as the one disclosed in the Italian Patent No. 1.235.584 of the same Applicant.
- This hinge, shown in a prospective view in Fig. 1, is substantially constituted by a first member 1, aimed at being fastened to the frame structure of the electric household appliance A, and a
second member 2, aimed at being fastened to the door P of the electric household appliance, pivotally connected to the first member 1 in 3. - In order to counterbalance the door weight, the hinge is provided with a mechanism constituted by cooperating
members 4, 5, 6, located between the first and the second members, as described in the above mentioned Italian Patent. - The member 6 is connected with a counterbalancing system that has an extendible member 7 formed by a first spring end connecting member 8, a
helical spring 9, that is subjected to tensile stress, and a second springend connecting member 10, fixedly fastened, by means of asquare plate 11, to the frame structure A of the electric household appliance. - During the opening operation, the free end of the member 6, connected to the first spring end connecting member 8, moves away from the
square plate 11, and the extendible element 7 extends, gradually increasing the reaction force caused by thespring 9, that is subjected to the tensile stress, and thus counterbalances the torque produced by the door weight. - The torque increases in accordance with the lever arm increase that depends on the door opening angle.
- While closing the door, the
spring 9 is gradually released, reducing the counterbalancing force. - This type of counterbalancing system produces various drawbacks, some of which are mentioned below.
- If the spring breaks, the counterbalancing force does not exist any longer, and the door is free to turn downwards, provoking the risk of accidents and serious damages to the appliance.
- The use of helical spring, subjected to tensile stress, results in low fatigue strength and considerable waste of elastic material used to produce the springs.
- Moreover, it is not possible to adjust and/or change the counterbalancing force, if the hinge is mounted on the appliance and the same hinge cannot be used for different electric household appliances with doors of different weights.
- The main object of the present invention is to propose a counterbalancing system that resolves the above reported problems by making use of a spring that is subjected to compressive stress, and means for adjusting the counterbalancing force.
- Other features of the invention, not resulting from what has been stated, will be better seen from the following description in accordance with the contents of claims and with reference to the enclosed drawings, in which:
- Fig.1 shows a hinge for household appliance equipped with a counterbalancing system made in accordance with the prior art;
- fig.2 shows a lateral view of a hinge equipped with the counterbalancing system of the present invention, when the hinge is closed;
- fig.2A shows a particular of the hinge illustrated in fig. 2;
- fig.2B is a sectional view taken along the line B-B of fig. 2;
- fig.3 shows the same view as Fig.2, but with the hinge open;
- fig.3A is an enlarged sectional view taken along the line A-A of fig.3;
- fig.4 is an enlarged view of particular B of fig.3 in a different functional position;
- fig.5 shows a constructive variant with the hinge closed;
- fig.6 shows the same variant illustrated in fig. 5, but with the hinge open;
- fig.7 shows a perspective view of a particular of the variant shown in fig.5.
- With reference to the drawings, the adjustable counterbalancing system, that is the subject of the present invention, is applied to a particular kind of hinge, described in the introductory part, such as the one disclosed in the Italian Patent No. 1.235.584, but it is obvious that this type of hinge has been used as a mere example, therefore the same system can be applied also to other types of hinge, performing the same function within the same inventive idea.
- With reference to figs.2 and 3, the hinge includes a
first member 101, fastened to the frame structure of the electric household appliance and asecond member 102, fastened to the appliance door. - The two
members - The
member 101 has a transversal "C"-like part that defines threewalls 101a, 101b, 101c (see fig. 2B). - Moreover, the system is equipped with a mechanism that includes cooperating
members first member 101 and thesecond member 102. - The free end of the
member 106, that protrudes from the mechanism, moves in accordance with the hinge opening-closing movement. - With reference to fig.2, the lower end of a
link member 21 is carried, pivoted in 20, by themember 106, while the other end of thelink member 21 is engaged with an end of anextendible member 22. - The
extendible member 22 includes two "T"-likeflat bars helical spring 23, set around the flanked stems of the "T"-like bars, so as to be compressed between the two opposite heads of the "T"-like bars. - The end, opposite to the head, of the
bar 22a, is fastened to thelink member 21, while the corresponding end of the otherflat bar 22b, opposite to the above mentioned head of theflat bar 22a, is connected with the free end of acable 24. - The
cable 24 extends upwards and then is sent downwards turning around aroller 25 that is rotatably supported by themember 101. - The other end of the
cable 24 is fixed in apoint 26 by aclamp 27 constituting a part of a guide-support plate member 28 (fig. 3A). - The guide-
support plate member 28 includes a plate, fixed to themember 101 by nails orrivets 29, and featuring aslot 30 that acts as a horizontal guide for a cylindricalsmall barrel 31. - A
pin 33, acting as a stationary stop, is also fastened to theplate member 28. - The
barrel 31, as seen in fig. 3A, has afirst groove 31a that engages thecable 24, a second groove 31b, and a threaded hole 31c. - The second groove 31b engages slidingly with the
slot 30 so as to obtain a guided sliding connection between thebarrel 31 and the guide-support plate member 28. - The threaded hole 31c engages a
screw 32, thehead 32a of which rests turningly against thewall 101a of themember 101, so that it is possible to act on thehead 32a of the screw by akey 34 from outside of thewall 101a. - The above described counterbalancing system exploits the elastic reaction of the
helical spring 23, that is pre-loaded according to a predetermined value, when the door is closed, and, during opening of the door, the spring is gradually compressed between the wider heads of the twoflat bars - According to a constructive variant, illustrated in figures 5, 6, 7, the free end of the
cable 24 is fixed directly to alink member 121, functionally similar to theanalogous member 21, and theextendible member 22 is subjected, by interpositions of aroller 125, to the stresses transmitted thereto by thecable 24 during the door opening. - More precisely, the end of the
flat bar 22b of theextendible member 22, opposite to the head, is shaped in such a way that it can hook in a seat 101d made in the member 101 (fig.7), while the respective end of theother bar 22b features afork 122, that bears rotatably theroller 125, sending back downwards thecable 24. - In this way, when the door is opened, the
member 121 moves down (fig. 6), causing the stress theextendible member 22, and subsequently, compression of thespring 23, like in the previously described solution. - The main advantage of the described system, in both proposed versions, results from the fact that, if the
spring 23 breaks, i.e. as usually happens when the wire of which the coils are made breaks, the counterbalancing force does not stop to act, but continues to exert its action, although with a slightly lower intensity, since thespring 23 remains still compressed between theflat bars - It is to be pointed out, that after the hinge has been mounted on the appliance, it is possible to adjust the counterbalancing action of the
extendible member 22 without removing the hinge. - This is performed by inserting of a
suitable key 34 in the head of thespring 32 and rotating the spring in order to move thebarrel 31 leftwardly or rightwardly (see fig. 4). - The
barrel 31 movement causes releasing or tensioning of thecable 24, that, correspondingly reduces or increases the compression of thepre-loaded spring 23, that results in reduction or increase of the counterbalancing action. - Another advantage results from the fact that the
spring 23 is subjected to compressive stress, therefore its production requires less elastic wire and its fatigue strength is increased with respect to a helical spring subjected to tensile stress. - It is also to be pointed out that the
spring 23 can be used to define the maximum hinge opening by adjusting thebarrel 31 using thescrew 32 until the turns of thespring 23 are packed when the hinge is opened at most.
