Flerein the first bracket (20) is connected to the second bracket (30) in an articulated manner via the first and the second linkage members (60, 70) and the second bracket (30) is mounted onto the mounting plate (40). One end of the second linkage member (70) is fastened to the second bracket (30) by means of a first pin (33) and the other end of the second linkage member (70) is fastened to the first bracket (20) by means of one arm of a u-shaped connector (23). On the other hand, one end of the first linkage member (60) is fastened to the second bracket (30) by means of a third pin (35) and the other end of the first linkage member (60) is fastened to the first bracket (20) by means of the other arm of the u-shaped connector (23). The first linkage member (60) and the second linkage member (70) are connected between the first bracket (20) and the second bracket (30) such that the first linkage member (60) and the second linkage member (70) are spaced apart each other. Preferably, the side walls of the second linkage member (70) enclose the first linkage member (60).
Figure 3 shows the furniture hinge (10) of the Figure 2 in an exploded state and the components of the furniture hinge (10) are seen here in a greater detail. The first bracket (20) comprises a cup region (22) formed as a depression proceeding from an external face (22.5) which defines a stop for the mounting travel of the first bracket (20) into the bore opened on the furniture door. The cup region (22) which has a base (22.1 ) and a wall (22.2) rising up to the external face (22.5) is formed by a central region (22.3) and a connection region (22.4) that has a narrower internal space than the those of the central region (22.3) and transitions to the central region (22.3) in the same depression. The connection region (22.4) is embodied in the same cup region (22) with the central region (22.3) which is formed substantially in a rounded manner, while the connection region (22.4) provides an outwardly extended form in relation to the central region (22.3). When the furniture door is closed onto the furniture cabin, the first bracket (20) is articulated relative to the second bracket (30), the first and second linkage members (60, 70) are pivoted at the connection region (22.4) and housed in the cup region (22). The connection region (22.4) includes two pin holes (10.2) cut-out in the wall (22.2) which correspond to other two pin holes (10.2) formed on the opposite wall (22.2), by means of those pin holes (10.2) the first linkage member (60) and the second linkage member (70) are connected to the first bracket (20) via the u-shaped connector (23) so as to be spaced apart each other, as seen in figure 8.
The second linkage member (70) includes two pin holes (10.2) as cut-out in a side wall of the second linkage member (70) which correspond to two pin holes (10.2) in the opposite side wall. Said pin holes (10.2) are advantageously provided near ends of the side walls of the second linkage member (70). By way of those opposed pin holes (10.2) the second linkage member (70) is pivotally connected to the second bracket (30) with the help of the first pin (33), and to the first bracket (20) with the help of one arm of the u-shaped connector (23), as seen in figure 2. As seen in the figure 3, the first linkage member (60) comprises a main body (61 ) having a fastening hole (62) at one end which may be formed by being bended of the main body (61). The first linkage member (60) is connected to the first bracket (20) by means of one arm of the u-shaped connector (23) which passes through the respective pin holes (10.2) in the connection region (22.4) and the fastening hole (62).
The first linkage member (60) further comprises a supporting part (63) formed on the other end of the main body (61 ). The supporting part (63) comprises two claws (63.1) disposed at sides of the end of the main body (61 ). Each of said claws (63.1 ) comprises a pin hole (10.2) and a nail portion (63.2). The first linkage member (60) is pivotally connected to the second bracket (30) by means of the third pin (35) which is guided through the pin holes (10.2) cut out in the claws (63.1 ). The further aims of the supporting portions (63) of the first linkage member (60) will be explained later in the following.
The furniture hinge (10) further comprises a torsion spring (80) fitted around the first pin (33) for urging the furniture door to move from an opened position to a closed position relative to the furniture cabin. The torsion spring (80) is connected around the first pin (33) to be strained in the space between the first linkage member (60) and the second linkage member (70) and has a short arm (80.1 ) configured to be secured to internal face of the second bracket (30) so as to be retained immovably there by a second pin (34) and a long arm (80.2) configured to lean on the u-shaped connector (23).
The second bracket (30) comprises an outer body (31 ) having a first screw hole (38) and a second screw hole (39) formed as a slot surrounded by a knurled area (39.1 ). The second bracket (30) is connected to the mounting plate (40) by means of the first adjustment element (36) which is guided through the first screw hole (38). Further the second bracket (30) is also connected to the mounting plate (40) and aligned therewith by means of the second adjustment element (37) which is guided through the second screw hole (39). The transverse adjustment of the outer body (31 ) according to the mounting plate (40) is realized via the second adjustment element (37) interacting with the knurled area (39.1 ). The first screw hole (38) corresponds to a first mounting slot (41 ) formed on the mounting plate (40), while the second screw hole (39) corresponds to a third screw hole (42) of the mounting plate (40). The first adjustment element (36) includes a stopper head (36.1 ) and a guide portion (36.2) to which a first seating surface (41 .1 ) of the first mounting slot (41 ) is introduced such that the stopper head (36.1 ) is located underside of the first seating surface (41 .1 ) in the mounting position and prevents detachment of the second bracket (30) from the mounting plate (40). The third screw hole (42) includes straight knurled ways (42.1 ) at its both sides which cooperate with the knurled area (39.1 ) of second screw hole (39). By way of screwing the second adjustment element (37) through the second screw hole (39) and the third screw hole (42), the knurled area (39.1 ) and the knurled ways (42.1 ) allow the longitudinal progress of the second adjustment element (37) thereon and provide transverse adjustment of the second bracket (30) according to the mounting plate (40).
The second bracket (30) further comprises connection flaps (31.1 ) incorporated in the side walls of the outer body (31 ) and by way of which a damping mechanism (90) having a damper (91 ) and a housing (92) is slidebly held inside the second bracket (30). The connection flaps (31 .1 ) may be formed as protrusion by inwardly bending of a portion of the side walls of the outer body (31 ). A housing slot (45) is disposed on the mounting plate (40) into which the housing (92) is introduced in a linearly movable manner.
Figure 4 shows the damping mechanism (90) removed from the second bracket (30) wherein the damper (91 ) in the released state is partially extended out from the housing (92). Figure 5 shows the damper (91 ) and the housing (92) for receiving the damper (91 ) in a perspective exploded illustration. The illustration shows the damper (91 ) facing the housing (92) in an insertion direction. The damper (91 ) comprises a cylinder body (91.1 ) and a piston rod (91 .2) received into the cylinder body (91 .1 ) in a slideble manner. The damper (91 ) advantageously provides an enlarged body portion (91.4) surrounding the end of the cylinder body (91.1 ) opposite to the free end thereof. The enlarged body portion (91 .4) may be the contact surface with the inner periphery of the housing (92) in order to reduce the friction surface between the cylinder body (91.1 ) and the housing (92) while damping movement. This results in the reduction of the wearing between the components as well as noise during damping.
In a mounted position of the damping mechanism (90) within the second bracket, the free end of the cylinder body (91.1 ) which is extended out from the housing (92) bears on the second pin (34) and the free end of the piston rod (91 .2) is supported inside the housing (92). The piston rod (91 .2) may have a knob (91 .3) in the free end thereof. In this case, the knob (91.3) is supported in the housing (92). Thereby, in case the articulation of the first bracket (20) in relation to the second bracket (30), the movable housing (92) drives the piston rod (91 .2) into the cylinder body (91 .1 ) which is securely supported by the second pin (34) on the free end thereof.
The housing (92) comprises a flat face (92.4) molded onto a dished face (92.3) into which the damper (91) is introduced. In the assembled position, the flat face (92.4) slidebly seats on the inner face of the outer body (31 ). The flat face (92.4) provides guiding webs (92.5) on both sides, by way of which the housing (92) is slidebly held onto the connection flaps (31.1 ) of the second bracket (30). A ramp (92.6) may be disposed on the rear end of the flat face (92.4) for providing more compact form besides ease of sliding movement of the housing (92) within the second bracket (30). The rear side of the housing (92) is received within the housing slot (45) of the mounting plate (40) in a linearly movable manner in relation to therein.
The figure 6 shows the housing (92) in both rear view and front view respectively in a perspective manner. As seen in the figure, the dished face (92.3) is formed with a front opening (92.7) through which the damper (91) is introduced into the housing (92) and with a rear opening (92.8) partially closed with a limiting surface (92.2) which is molded on the rear side of the flat face (92.4) and supports the free end of the piston rod (91 .2), preferably the knob (91 .3).
The housing (92) further comprises a rim (92.1 ) molded on the front side of the flat face (92.4) opposite to the limiting surface (92.2). The front opening (92.7) of the dished face (92.3) is incorporated into the rim (92.1 ) of the housing (92), thereby the cylinder body (91.1 ) of the damper (91 ) is extended out from the front opening (92.7) on the rim (92.1 ). To this end, the damper (91 ) is supported between the limiting surface (92.2) of the housing (92) onto which the free end of the piston rod (91 .2) bears and the second pin (34) pivotably mounted on the second bracket (30) onto which the free end of the cylinder body (91.1 ) bears.
The figure 7 shows a sectional view of the damping mechanism (90) wherein the damper (91 ) is extended out from the housing (92) in the released position. The damper (91 ) is housed within the housing (92) by being supported by the limiting surface (92.2) over the end of the piston rod (91.2), preferably the knob (91.3). The enlarged body portion (91.4) of the cylinder body (91.1 ) is in contact with the inner periphery of the housing (92), and the rest portion may advantageously provide a clearance from inner periphery of the housing (92).
The figure 8 shows the sectional view of the furniture hinge (10) in the assembled form without a mounting plate (40). The damping mechanism (90) is slidebly secured inside the outer body (31 ) via the connection flaps (31.1 ) such that the guiding webs (92.5) are engaged on the connection flaps (31.1 ) of the second bracket (30) and the free end of the cylinder body (91.1 ) bears onto the second pin (34). The knob (91 .3) of the damper (91 ) is supported by the limiting surface (92.2) of the housing (92). The supporting portion (63) of the first linkage member (60) rests against to the rim (92.1 ) of the housing (92). In the articulation of the first bracket (20) in relation to the second bracket (30), the housing (92) is pulled by the supporting portion (63) of the first linkage member (60) with the help of the rim (92.1 ) of the housing (92) and the piston rod (91 .2) is pushed into the cylinder body (91 .1 ), the free end of which is secured on the second pin (34). Thereby the damping impact occurs on the furniture door while being closed onto the furniture cabin.
