Description
~2~2~~
The present invent:Lon relates to a hinge for furni-ture doors with a closing mechanism, comprising a hinge casing on the side of the door, and a hinge arm on a side panel of the piece of furniture, the inner ends of two hinge links being pivotally mounted in said hinge casing and the outer ends of said hinge links engaging on the hinge arm and forming a hinge quadrangle, a pressure member pre-stressed by spring pressure being pivotally mounted on the inner hinge arm nearer to said side panel and abutting on the hinge arm or a member rigidly connected to said hinge arm such as a hinge axle.
Such hinges having an integral closing mechanism are well known. It is their essential advantage that a separate closing member, e.g. a magnetic catch member, is not necessary on the piece of furniture.
Closing mechanism are generally such that the closed door is held in the closed position by the hinge so that, when the door is opened, there must first be acted against the spring pressure of the closing mechanism and after a dead cen-ter position has been overcome, the door is to be pressed out-wardly also by the closing mechanism into the open position.
, -- 1 --~L~iZ8~¢i~
When the door is closed, the closing mechanism operates vice versa in an analogous manner.
It is the main disadvantages of such hinges that the closing effect of the hinge starts, when the door is in a 45 open position, i.e. the door is still relatively wide open, so at a time when the actual effect of the closing mechanism is not yet desired. The doors of the piece of furniture are often banged because of the long e~fective closing path, thus causing undesired noise and, furthermore, creating disadvan-tages in respect of the high stresses acting on the axles and links of the hinge.
The present invention provides a hinge of the afore-mentioned kind in which the angle of the furniture door to the actual closing plane of the furniture door in which the clos-ing effect occurs can be freely selected and can be relatively small, preferably an angle of between 10 and 15. Hence, nei-ther when opening nor when closing the door, a dead center in the hinge musk be overcome. Furthermore, the closing mecha-nism in the hinge according to the invention is accommodated in the hinge arm in a very compact manner.
According -to the present invention there is provided a furniture door hinge including a closing mechanism, said hinge comprising: a hinge casing adapted to be mounted on a door; a hinge arm adapted to be mounted on a furniture wall;
inner and outer hinge links having respective first ends piv-otally mounted to said hinge casing by respective outer hinge axles and respective second ends pivotally mounted to said hinge arm by respective inner hinge axles, thereby forming a quadrangular linkage; said inner hinge link being in the form of a two-arm lever inclu~ing a first arm extending between the respective said outer and inner hinge axles and a second arm extending from said respective inner hinge axle in a direction ,~.
-.~ - 2 -3Z~6 awa~ from said respective outer hinge axle; said hinge arm having a guide surface; a pressure member extending between the inner hinge axles and being directly pivotally mounted on an axle fixed to said second arm at a position spaced from said respective inner hinge axle, said pressure member having a contact surface; and separate spring means for biasing said pressure member to pivot about said axle in a direction to urge said contact surface into direct abutment with a surface on the respective said inner hinge axle of said outer hinge link and in a direction toward said respective inner hinge axle of said outer hinge link in the closed position of the hinge and to urge said contact surface directly against said guide surface at all other positions of the hinge, said spring means comprising a ~ompression coil spring compressed between said first arm and said pressure member.
Thus according to the invention the inner hinge link is a two-arm lever and the pressure member is mounted outside the two hinge axles of the hinge link at the hinge link.
As the mounting point of the pressure member on the hinge link is not between the two hinge axles of the hinge arm, it takes up a minimum of space between the two hinge links and does therefore not interfere with the geometry of said links.
It is advantageously provided that an arm of the inner hinge link extends into the hinge arm and that the pres-sure member is pivotally mounted on that arm.
An embodiment of the invention provides that the pressure member is acted upon by a leg spring mounted on the arm extending into the hinge arm or that the pressure member is the leg of a leg spring pivotally mounted on the arm of the hinge link extending into the hinge arm.
By using a leg spring high functional safety is ~ ~,2~ 6 obtained by simple means as said leg spring can unlike a coil spring be easily anchored in the hinge arm without requiring any guide means. Moreover, an additional pressure member need not be provided in the closing mechanism.
A further embodiment provides that a separate insert member is arranged on the hinge arm, sald insert member extending over the total displacement path of the pressure member and carrying the pressure surface designed as the guide surface for the pressure member. Hence, the hinge arm need not be specially manufactured for the closing mechanism.
In a particular advantageous aspect thereof the pre-sent invention provides a hinge for ~urniture doors with a closing mechanism, comprising a hinge casing at the side of the door~ and a hinge arm at a side panel of the piece of fur-niture, the inner ends of two hinge links being pivotally mounted in said hinge casing and the outer ends of said hinge links engaging on the hinge arm and forming a hinge quadran-gle, a pressure member pre-stressed by spring pressure being pivotally mounted on the inner hinge arm nearer to said side panel and abutting on a hinge axle, wherein said inner hinge link is a two-arm lever with an arm extending into said hinge arm and said pressure member is pivotally mounted on said arm, said pressure member is acted upon by a leg spring mounted on said arm of said hinge link extending into said hinge arm or is a leg of a leg spring pivotally mounted on said arm of said hinge link extending into said hinge arm, wherein in the closed position as well as in the open position of the hinge the said leg spring presses with its two legs on the two hinge axles of said hinge arm. ~uitably, said leg of said leg spring pressing on said hinge axle of said external hinge link is discontinuously curved and describes a guide curve for the guiding of the closing pressure. Desirably, said leg of said P~
`~t - 3a -8~
leg spring has two curved portions with oppositely directed curvatures, Preferably, said leg spring surrounds with its middle loop a bolt of said arm of said inner hinge link.
In the following embodiments of the invention will be described in more detail by means of the figures of the - 3b -:l~Z~
r? y ~
a~ ,ached drawings in which ~igure 1 shows a sectional view of a hinge according to the invention in the closed position, Figure 2 shows the same sectional view of a hinge according 5 to the invention in the open position, Figure 3 shows a sectional view of the hinge arm in the region of the closing mechanism of a second embodiment, Figure 4 shows a sectional view analogous to Fig.3 of a third embodiment of the invention, 10 Figure 5 shows a sectional view along line I-I of Fig.4, Figure 6 shows a sectional view of a furhter embodiment of a hinge according to the invention in the closed posi-tion, Figure 7 shows the same sectional view of the hinge in 15 the open position of the hinge, and Figure 8 shows a sec-tional view of the insert member and the pressure member.
As can be seen from the figures of the drawing, the hinge according tc the inventicn has a hinge ar:n 1 fastelled to a 20 furniture side wa:Ll 7 by means of a base plate 8. The base plate 8 is fastened at ~ e furniture side wall 7 in a conventional manner by mearls of screws or dowels. The hinge arm 1 is retained on the base plate 8 by means of a clamping screw 10. An adjusting screw 11 for the adjustment of the 25 joint is also provided on the hinge, said adjusting screw being mounted in a female thread in the hinge arm 1 and abutting against the base plate 8. The hinge casing 2 of the hinge is inserted into the door 9.
The hinge arm 1 is connected with the hinge casing 2 30 by means of hinge links 3,6 mounted on hinge axles 12, 13 on the hinge arm 1 and on hinge axles 14, 15 in the hinge casing 2 The inner hinge link 6 is a two arm lever pivoting around the hinge axle 12 of the hinge arm 1. At the free end of 5 the arm 6' of the hinge link, i.e. outside the points of bearing of the hinge axles 12, 14, the pressure member 4 with its holding arm 17 is moun-ted on a bolt 16. ~he pressure member 4 is, hence, pivotable around the bolt 16 but a pivoting motion is not possible because the path of the 10 pressure member 4 is limited by the hinge link axle 13 and by the support surface 18 on the hinge arm 1. In the embodiment according to ~igs. 1,2 and 6,7,8 the pressure member 4 has a holding arm 17.
In the embodiments accoridng to Figs. 1,2 and 6,7,8 the 15 pressure member 4 receives a pressure spring 5 abutting against the internal hinge link 6, be-tween the hinge link ;~ axles 12 and 14, i.e. on the second hinge link arm 6".
Due to the arrangement of the pressure rnember 4 according to the invention the latter-mentioned abuts in the closed 20 position of the door 9 against the hinge link axle 13 and presses the internal hinge link 6 in-to -the closing direc-tion, i.e. the door 9 is held in the closed position.
When the door 9 is opened or is moved on the opening path, the pressure member 4 moves in the embodiments according 25 to Figs. 1,2 and 6,7,8 from the hinge axle 13 to the stop surface 18 on the hinge arm 1 but no load is taken from the :L;~;~8Z(~6 pressure spring 5, i,e, the pressure member 4 and the pressure spring 5 are equally tcnsioned.
When the door 9 is closed, the pressure member ~ moves back to the hinge axle 13 but -the tensioning condition 5 of the pressure spring 5 is not changed, i.e. with the hinge according to the invention, the person using the piece o~ furniture need not tension the pressure spring neither when closing nor when opening the hinge, and no banging of the door 9 occurs, It is obvious that no dead center must be overcome but nevertheless the door 9 is absolutely securely held in the closed position by the pressure spring 5.
The curve of the pressure surface on the pressure member 4 can obviously be selected such -that the door 9 is closed at a desired angle, e.g. o~ 10, to the closing plane.
In the embodiment according to Figs. ~,7,8 a separate insert member 19 o~ plastic material with a closing region 18" is provided on -the hinge arm, the pressure member 4 pressing against said insert rnember. The insert member 19 is mounted on the hinge axle 13 and abuts on the edge 20 of the hinge arm 1.
Due to the arrangernent according to the invention o~ the insert member 19 the pressure member 4 abuts on the same structural member in the closed position of the door 9 (as shown in Fig.6) as well as in the opened position.
When the door is opened and closed, the pressure member 4 moves along the pressure surface 18. There again no load il2~6 is taken from -the pressure spring 5, i.e. the pressure member 4 and the pressure spring 5 are equally -tensioned.
The curve of the pressure surface 1~3 at the insert member 19 can obviosly be selected such that the door 9 is closed at 5 the desired angle, e.g. of 10, to the closing plane. ~linges may also be provided with different insert members 19 with differently extending pressure surfaces 18. In this manner, different closing angles are obtained without necessitating any changes of the hinge arm as such.
10 The closing mechanism in the embodiment according to Figs.4 and 5 has; a leg spring 21 which, in the one side, abuts against the hinge axle 12 of the internal hinge link ~ on the hinge arm 1 and, on the other side, on the pressure member 4.
15 The pressure member 4 is like the leg spring 21 hingedly connected with -the internal hinge 'ink 6.
The pressure member 4 has a path 22 which forms a guide curve t`or the closing pressure. Said moving pa-th 22 comprises two portions 22', 22" with oppositely directed curves. Portion 20 22' corresponds to -the open position of the hinge. In the closed position the pressure point D lies between the two portions 22', 22".
The pressure member 4 abuts with its path 22 on the hinge axle 13 of the hinge arm 1 for the external hinge link 3.
25 A roller 23 is arranged around the hinge ax:Le 13 to reduce lZ~8Z~6 the friction between the pressure member 4 and the hinge axle 13.
In this embodiment the pressure member 4 is provided with a lateral stop 24 for the leg spring 21.
5 In the embodiment according to Fig.3, a separate pressure member is not provided. The leg spring 21, which is again mounted on a bolt 16 of the internal arm 6' of the hinge link 6, abuts directly on the hinge axles 12, 13 of the hinge arm 1. The hinge axle 13 of the external hinge link 3 10 on which the leg of the leg spring 21 designed as the pressure member 4 is displaced is like in the afore-described embodi-ment provided with a roller 23 to reduce friction.
The leg of the leg spring 21, which leg is the pressure member 4, has two curved portions 4' and 4" with oppo-15 sitely extending curves. The external curve portion 4'corresponds to ~he open position oi the hinge. In the closed position the presaure point lies between said leg of the leg spring 21 and the roller 23 of the hinge axle 13 between the portion 4' ànd the portion 4" of the leg of 20 the leg spring 21 designed as the pressure member 4.
In Figs. 3, 4 the hinge is shown in the closed position.
The present invent:Lon relates to a hinge for furni-ture doors with a closing mechanism, comprising a hinge casing on the side of the door, and a hinge arm on a side panel of the piece of furniture, the inner ends of two hinge links being pivotally mounted in said hinge casing and the outer ends of said hinge links engaging on the hinge arm and forming a hinge quadrangle, a pressure member pre-stressed by spring pressure being pivotally mounted on the inner hinge arm nearer to said side panel and abutting on the hinge arm or a member rigidly connected to said hinge arm such as a hinge axle.
