[0050] FIG. 1 shows an article of furniture 1 with a two-part furniture flap 3 fixed to a furniture carcass 2 in an upwardly folded, that is to say opened, position. In this arrangement the two-part furniture flap 3 comprises a first flap part 31 and a second flap part 32, wherein there is provided a handle 6 for better operability by a user at the lower edge of the second flap part 32. The support device 4 is concealed by the furniture flap 3 in this view.
[0051] FIG. 2 shows a sectional side view of an article of furniture 1 in an opened position approximately corresponding to FIG. 1. In this arrangement the article of furniture comprises the furniture carcass 2, the support device 4 fixed thereto and the two-part furniture flap 3 with a first flap part 31 and a second flap part 32. A handle 6 for actuation of the furniture flap 3 is provided on the second flap part 32. The housing 48 of the support device 4 is mounted in an upwardly disposed region of the furniture carcass 2, in which case mounting of the support device 4 can be effected at a side wall of the furniture carcass 2 or also at the underside of the top panel of the furniture carcass 2. The first flap part 31 of the furniture flap 3 is connected to the housing 48 by way of a first hinged connection 46. As will be further apparent hereinafter this first hinged connection can be a four-point concealed cup hinge. The first flap part 31 can also additionally be fixed to a guide portion 45 of the support device 4. The second flap part 32 is connected to the first hinge part 31 with a second hinged connection 47. The second hinged connection 47 between the flap parts 31, 32 can be a two-point concealed cup hinge, as will be further apparent hereinafter. The first hinge lever 41 is also mounted rotatably to the housing 48. That first hinge lever 41 engages the transmission portion 40 at a first articulation point 43. The second hinge lever 42 in turn engages the second articulation point 44 of the transmission portion 40. The second hinge lever 42 is hingedly connected to the second flap part 32, in the embodiment shown here that connection is made by way of the second hinged connection 47. In this position corresponding to the open position of the furniture flap 3 the first hinge lever 41, the transmission portion 40 and the second hinge lever 42 are substantially aligned with each other. It will also be clearly visible from this view that access to the interior 20 of the furniture carcass 2 is not impeded by components projecting therefrom. The support device 4 can also have an electric drive 5 which cannot be seen from the exterior.
[0052] In the sectional view of the article of furniture 1 shown in FIG. 3 the two-part furniture flap 3 is in an intermediate position between the completely opened and the completely closed state. The pivotal movement of the first hinge lever 41, which is caused by the setting angle of the first flap part 31 which is reduced in comparison with FIG. 2, relative to the furniture carcass 2, is transmitted by the transmission portion 40 to the setting angle between the second flap part 32 and the first flap part 31 with the second hinge lever 42 so that upon closure of the two-part furniture flap 3 there is a pivotal movement of the second flap part 32 with respect to the first flap part 31. Transmission of the setting angle of the first flap part 31 to the setting angle of the second flap part 32 in relation thereto is made possible by the transmission portion 40 which is guided linearly on a guide portion 45 and which bears against the inside of the first flap part 31 over the entire range of pivotal movement, and thus allows controlled pivotal movement of the second flap part 32 with respect to the first flap part 31 upon opening or closing of the two-part furniture flap 3.
[0053] FIG. 4 shows an article of furniture 1 in a completely closed position of the two-part furniture flap 3. The first hinge lever 41, the transmission portion 40 and the second hinge lever 42 of the support device 4 are substantially in alignment with each other in this closed position of the two-part furniture flap 3, whereby the amount of space required by the support device 4 can turn out to be very small.
[0054] FIGS. 5a through 5c show the opening and closing movement of a two-part furniture flap 3 of an article of furniture 1. In this respect FIG. 5a shows an article of furniture 1 with a completely closed two-part furniture flap 3, FIG. 5b shows an article of furniture 1 with a two-part furniture flap 3 in a partially opened or closed position and FIG. 5c shows an article of furniture 1 with a completely opened two-part furniture flap 3.
[0055] In that respect it can be clearly seen that upon opening or closing of the two-part furniture flap 3 the downwardly arranged second flap part 32 is pivoted with respect to the first flap part 31 by the support device 4 in such a way that it is displaced almost perpendicularly upwardly and downwardly respectively. That is contrary to operating comfort and convenience for a user as upon opening or closing of the two-part furniture flap the lower second flap part 32 in that case pivots substantially no further out from the furniture carcass 2 than the lower edge of the upper first flap part 31. In that case, the part of the support device 4 which bears against the inside of the first flap part 31 substantially follows the contour of the two-part furniture flap 3 and thus permits optimum accessibility for a user to the interior 20 of the furniture carcass 2. Optimum operating safety is also achieved by the elimination, which is made possible in that way, of any additional control elements which are provided separately from the flap parts 31, 32 and which project from the furniture carcass 2.
[0056] FIG. 6 shows a perspective rear view of a support device 4 in a position corresponding to a closed position of a two-part furniture flap 3 (not shown). In this case the housing 48, the first hinge lever 41 hingedly fixed thereto, the transmission portion 40 connected thereto at a first articulation point 43 and the second hinge lever 42 hingedly connected thereto at the second articulation point 44 can be clearly seen. In this view the guide portion 45 which is connected to the first hinged connection 46 and the second hinged connection 47 is concealed. In this embodiment the second hinge lever 42 is connected to the second hinged connection 47 by way of a fitting 49. The transmission ratio in terms of transmission of the setting angles of the flap parts 31, 32 of a furniture flap 3, that are provided for mounting to the hinged connections 46, 47, can be adjusted by the fitting 49 in addition to the transmission ratio provided by the proportions of the hinge levers 41, 42 to the transmission portion 40. When using a fitting 49 the first hinge lever 41, the transmission portion 40 and the second hinge lever 42 can further be substantially in alignment with each other.
[0057] FIG. 7 shows a perspective rear view of a support device 4, the position of which corresponds to a partially opened or closed position of a two-part furniture flap 3 (not shown). In that respect it can be seen that the first hinged connection 46 connected to the housing 48, in this embodiment in the form of a four-link concealed cup hinge, is partially opened. A part of the guide portion 45 is also visible by virtue of the pivotal movement of the first hinge lever 41 in that position of the support device 4. By virtue of the linear relative movement caused by the pivotal motion between the transmission portion 40 and the guide portion 45, the second hinged connection 47 by way of the second hinge lever 42 and the fitting 49 can be so modified in its setting angle that a flap part 32 intended for mounting thereto would be held in an almost perpendicular position.
[0058] FIG. 8 shows a perspective rear view of a support device 4, the position of which corresponds to an almost completely opened two-part furniture flap 3. The first hinged connection 46 which in this embodiment is in the form of a four-link concealed cup hinge, is equally disposed in an almost opened condition. The transmission portion 40 which is guided linearly at the guide portion 45 has moved in this position of the support device 4 relative thereto from a lower end of the guide portion 45—presupposing an opening movement—in the direction of an upper end of the guide portion 45, and thus transmitted a pivotal movement of the first hinged connection 46 to the second hinged connection 47 by way of the second hinge lever 42 and the fitting 49.
[0059] FIG. 9 shows a perspective rear view of a support device 4 in a position corresponding to a completely opened two-part furniture flap 3. The first hinged connection 46 which is in the form of a four-point hinge, between the housing 48 and the guide portion 45, is disposed in this case in an open position, in other words a pivoted outwardly or also extended position, and the second hinged connection 47 in the form of a two-point concealed cup hinge, between the guide portion 45 and the second hinge lever 42, is in a closed position, in other words in an angled-in or folded-in position. The transmission portion 40 is displaced with respect to the guide portion 45 to the maximum in the direction of the first hinged connection 46, which is characteristic of the position of the support device 4, that corresponds to the opened position of a two-part furniture flap 3. In this embodiment the positive guidance is afforded by the transmission portion 40 engaging behind the guide groove 6 provided on the guide portion 45. The desired tilting movement of the second hinged connection 47 in the position of the support device 4, that corresponds to the opened position, can be adjusted by way of the dimensions of the fitting 49.
[0060] FIGS. 10a and 10b show a side view and a perspective front view of a position of the support device 4, corresponding to a closed position of a two-part furniture flap 3. In this position the transmission portion 40 is displaced relative to the guide portion 45 to the maximum in the direction of the second hinged connection 47. The first and second hinged connections 46, 47 which are in the form of a four-point and two-point concealed cup hinge respectively are respectively disposed in a position in which a flap part 31, 32 of a two-part furniture flap 3, that is intended for mounting thereto, would be respectively disposed in a perpendicular position. The first hinge lever 41, the transmission portion 40 and the second hinge lever 42 are substantially aligned with each other. In this position the first hinged connection 46 which is in the form of a four-link concealed cup hinge is disposed in a closed condition, whereas the second hinged connection 47 which is in the form of a two-point concealed cup hinge is in an opened condition.
[0061] FIGS. 11a and 11b show a side view and a perspective front view respectively of a support device 4 in an intermediate position. The first hinged connection 46 which is in the form of a four-point concealed cup hinge and the second hinged connection 47 which is in the form of a two-point concealed cup hinge are disposed in this case in a partially opened and closed condition respectively. The transmission portion 40 is approximately at half the displacement travel which is possible relative to the guide portion 45, between the lower and upper end positions of the guide.
[0062] FIGS. 12a and 12b show a side view and a perspective front view respectively of a support device 4 in a position corresponding to an opened position of a two-part furniture flap 3. The first hinge lever 41, the transmission portion 40 and the second hinge lever 42 are in this case again aligned with each other. The transmission portion 40 is in an upper end position in its displacement travel relative to the guide portion 45. The first hinged connection 46 in the form of the four-point concealed cup hinge is in a completely opened condition and the second hinged connection 47 in the form of a two-point concealed cup hinge is in a completely closed condition. FIGS. 13a through 13c show a detail view of a portion of a two-part furniture flap 3 with a part of the support device 4 in an opening or closing movement. FIG. 13a shows a portion of the first flap part 31 and a portion of the second flap part 32. In addition it is also possible to see the second hinged connection 47 in the form of a two-point concealed cup hinge, thereby providing a hinged connection between the first flap part 31 and the second flap part 32. In this embodiment the second hinge lever 42 of the support device 4 is connected to the second flap part 32 by way of a fitting 49. The second hinge lever 42 further attaches to the transmission portion 40 at the second articulation point 44 thereof. The first flap part 31 can be fixed to the guide portion 45 of the support device 4 by way of screw means. The transmission portion 40 which is guided at the guide portion 45 is disposed in this position corresponding to the closed position of an article of furniture 1, in a lower end position in its displacement travel. FIG. 13b shows a portion of the support device 4 and the two-part furniture flap 3 in a partially opened or closed position. It can be seen here that the tilting movement of the first flap part 31, due to the relative displacement between the transmission portion 40 and the guide portion 45, has been transmitted with the transmission portion 40 by way of the second hinge lever 42 and the fitting 49 to the second hinged connection 47 and thus the second flap portion 32. FIG. 13c shows a part of the support device 4 and the two-part furniture flap 3 in a completely opened position. It is to be noted in this respect that the inclination of the second flap part 32 can be adjusted in the open position of the two-part furniture flap 3 by the fitting 49. In the embodiment illustrated here the second flap part 32 would incline away from the carcass 2 of an article of furniture 1, whereby it can be made easier for a user to be positioned under an opened furniture flap 3.
