DETAILED DESCRIPTION OF THE INVENTION
(7) FIG. 1a shows a support device 1 in a position corresponding to a closed position of a furniture flap 21. In this arrangement, the support device 1 has a housing 10 which can be mounted to a furniture carcass 20 and having a first support arm 11 mounted pivotably about a first pivot axis s1, and a second support arm 12 mounted pivotably about a second pivot axis s2 (not visible here). In this case, the first support arm 11 is further connected to a hinged connection 13 which is mounted rotatably about a first axis of rotation d1 and which is also connected to the second support arm 12 rotatably about a second axis of rotation d2. The movement of the first and second support arms 11, 12 is thus coupled by the hinged connection 13. In this position of the support device 1 (corresponding to the closed position), the second support arm 12 is arranged partially in the cavity afforded by the profile of the first support arm 11 substantially over the entire length of the second support arm 12 that projects from the housing 10, with respect to its heightwise extent. Thus, in the direction of viewing FIG. 1a (that is to say laterally or sideways with respect to the pivotal movement), possible in the counter-clockwise direction of movement of the first and second support arms 11, 12, there is a gap-free overlap between the two support arms 11, 12. The support device 1 further has a damping unit 16 which is fixed to the housing 10 and which, in this position of the support device 1 that corresponds to a closed position, in a maximum retracted state which occurs after a damping action has taken place, bears against the first support arm 11.
(8) FIG. 1b shows an intermediate position of the support device which corresponds to a position that occurs shortly after opening or shortly before closing of a furniture flap 21 which can be fixed to the support device 1. In comparison with the position shown in FIG. 1a, the first support arm 11 and the second support arm 12 are pivoted in the counter-clockwise direction (relative to this side view) about the first and second pivot axes s1, s2, respectively. The first support arm 11 now also no longer bears against the damping unit 16 which, as a result, is in a completely extended condition. By virtue of the inequality of the normal distance between the first and second pivot axes s1, s2 and the normal distance between the first and second axes of rotation d1, d2 (see FIG. 3), the pivotal movement of the first and second support arms 11, 12 gives rise to simultaneous translation and rotation of the hinged connection 13, and thus also translation and rotation of a furniture flap 21 which can be fixed thereto. Maintenance of the internested arrangement of the first support arm 11 and the second support arm 12 also results in this position in an overlap between the support arms 11, 12, which overlap is gap-free laterally or sideways with respect to the direction of movement.
(9) FIG. 1c shows the support device 1 in a position corresponding to an almost completely opened position of a furniture flap 21. In this position, the second support arm 12 is arranged substantially completely in the interior of the cavity afforded by the profile of the first support arm 11 and is thus not visible in this view. It can be clearly seen in contrast that the hinged connection 13 is tilted in relation to its starting position as shown in FIG. 1a, this being to a lesser degree than would occur for example in the case of the hinged connection 13 being non-rotatably connected to the first support arm 11. Rather, the coupling of the movement of the first and second support arms 11, 12 by the hinged connection 13, the arrangement of the first and second pivot axes s1, s2, the fixed arm length of the support arms 11, 12, and the arrangement of the first and second pivot axes s1, s2 results in a pivotal movement of the hinged connection 13 relative to the first support arm 11, which pivotal movement is oriented in opposite relationship to the direction of movement of the support arms 11, 12 of the support device 1.
(10) FIG. 1d shows the support device 1 in a position corresponding to a completely opened furniture flap 21. In this position, the support arms 11, 12 involve a maximum degree of internesting, wherein the second support arm 12 is arranged substantially completely within the cavity provided by the profile of the first support arm 11. Likewise, the hinged connection 13 is pivoted at its maximum with respect to the first support arm 11, whereby, for a furniture flap 21 which can be mounted thereto, it can be provided that the lower edge thereof is still in a region that a user can readily reach. In addition, the overlap of the two support arms 11, 12 that is gap-free in the lateral direction affords a user a particularly safe support device for a furniture flap as in that way it offers no possibility of inserting the hand or the fingers into a gap and becoming pinched upon pivotal movement of the support device.
(11) FIG. 2a shows a perspective view of a support device 1, wherein the hinged connection 13 is not shown for improved visibility of the end portions of the first and second support arms 11, 12. It is again firstly possible to see the housing 10 and the damping unit 16 which is fixed thereto and which acts on the first support arm 11. The first support arm 11 is mounted to the housing 10 pivotably about a first pivot axis s1, at a first end 11a which as shown is upward in the mounted position. Similarly thereto, at a first end 12a which as shown is arranged upwardly in the mounted position, the second support arm 12 is mounted to the housing 10 pivotably about a pivot axis s2. At a second end 11b of the first support arm 11, that as shown is downward in the mounted position, there is a first axis of rotation d1 for rotatable mounting of the hinged connection 13. Once again, similarly thereto at a second end 12b of the second support arm 12 which as shown is arranged downwardly in the mounted position, there is a second axis of rotation d2 for rotatable mounting of the hinged connection 13. The arrangement of the first axis of rotation d1 and the second axis of rotation d2 is also shown again in an enlarged portion A. The orientation of the first and second pivot axes s1, s2 and the orientation of the first and second axes of rotation d1, d2 are horizontal in this embodiment, and the direction of pivotal movement of the support arms 11, 12 can thus take place in a perpendicular plane.
(12) FIG. 2b shows a perspective view of a support device 1, the position of which corresponds to a position of a partially opened furniture flap. With the support device 1 in this position, the damping unit 16 precisely no longer bears or does not yet bear against the first support arm 11. As can be seen from the detail view A, the second support arm 12 substantially involves a cross-sectional shape of a rectangle. The second support arm 12 is also arranged in the interior of the U-shaped profile of the first support arm 11, partially along the heightwise extent of the second support arm, which is perpendicular in this view.
(13) FIG. 2c shows a perspective view of a support device 1 in a position corresponding to an almost completely opened furniture flap 21. In this case, the first and second support arms 11, 12 are only partially shown for better visibility of the profile shapes. As can be seen from the detail view A, the first support arm 11 has a cross-sectional shape substantially corresponding to a U-shaped profile. In the position of the support device 1 shown in FIG. 2c and corresponding to an almost completely opened position of a furniture flap 21, the second support arm 12 along its heightwise extent which is perpendicular in this view, is arranged substantially completely between the perpendicular flanks (legs) of the U-shaped profile forming the first support arm 11. The open side of the U-shaped profile of the first support arm 11 is towards a furniture flap 21 which can be mounted to the support device 1 (that is to say, the open side of first support arm 11 is substantially facing away from the internal space 22 of a furniture carcass 20 (see FIG. 5b)). In this configuration, the shape of the cross-section of the second support arm 12 substantially corresponds to a rectangle, in which case that cross-sectional shape is afforded by two mutually facing U-shaped profiles riveted in butting relationship.
(14) FIG. 3 shows a side view in section of a support device 1. In this case, the support device 1 is in a position corresponding to an open position of a furniture flap 21 (not shown). FIG. 3 shows the housing 10 of the support device 1 with a spring-loaded mechanical drive 14 which is arranged therein and which acts on the first support arm 11 by a control cam 15. Also provided on the housing 10 is a damping unit 16 for damping the closing movement of a furniture flap 21. The first support arm 11 is connected at a first end 11a to the housing 10 pivotably about a first pivot axis s1. At the second end 11b, the first support arm 11 is connected to a hinged connection 13 rotatably about a first axis of rotation d1. At the first end 12a, the second support arm 12 is connected to the housing 10 pivotably about a second pivot axis s2. At the second end 12b, the second support arm 12 is connected to the hinged connection 13 rotatably about a second axis of rotation d2. The hinged connection 13 which is connected in that way provides for coupling of the movement of the first and second support arms 11, 12 upon actuation of the support device 1. As can be seen in the position of the support device 1 shown in FIG. 3, the second support arm 12 is arranged in a substantially completely overlapping relationship with the first support arm 11 in the position of the support device 1 corresponding to an open position of a furniture flap 12. Thus, there is also no formation of a gap between the two support arms 11, 12 into which a user could laterally put their hand or the fingers and suffer damage thereto upon actuation of the support device 1. By virtue of the selection of the ratio of the normal distance between the first and second pivot axes s1, s2, as measured along a straight line connecting these pivot axes, and the normal distance between the first and second axes of rotation d1, d2, as measured along a straight line connecting these pivot axes, wherein that ratio in this embodiment is less than 1, the desired tilting movement of the angular position of the mounted furniture flap 21 relative to a furniture carcass 20 upon pivotal movement of a mounted support device 1 can be adapted to the height of a furniture carcass 20 or the height of a furniture flap 21.
(15) FIGS. 4a through 4d diagrammatically show various configurations of cross-sectional shapes of the first and second support arms 11, 12 of the support device 1. The position of the support device 1 can in this case correspond to an intermediate position between the opened and the closed end positions of the range of pivotal movement of the support device 1. In this case, the first support arm 11 has a cross-sectional shape substantially corresponding to a U-shaped profile.
(16) FIG. 4a shows a variant in which the second support arm 12 has a cross-sectional shape substantially corresponding to a U-shaped profile. In this case, the second support arm 12, over its heightwise extent, is arranged partially in the interior of the cavity afforded by the U-shaped profile of the first support arm 11, the open sides of the profiles of the first and second support arms 11, 12 respectively facing towards each other. In other words, the open side of the U-shaped profile of the second support arm 12 faces downward, while the open side of the U-shaped profile of the first support art 11 faces upward.
(17) FIG. 4b shows a variant of the support device 1 in which the second support arm 12 has a cross-sectional shape substantially corresponding to a U-shaped profile. The second support arm 12 is again partially overlapping with the first support arm 11, along the heightwise extent of the second arm. In this embodiment, the first and second support arms 11, 12 are so nested that the profiles are respectively oriented in the same way. In other words, the open side of the U-shaped profile of the second support arm 12 faces upward, while the open side of the U-shaped profile of the first support art 11 also faces upward.
(18) FIG. 4c shows a variant having a second support arm 12 which has a substantially rectangular cross-sectional profile.
(19) The cross-sectional shape of the second support arm 12 shown in FIG. 4d substantially corresponds to the cross-sectional shape of the second support arm 12 shown in FIG. 4c, but in FIG. 4d the cross-sectional area of the second support arm 12 is smaller than the cross-sectional area of the second support art 12 of the embodiment shown in FIG. 4c.
(20) FIG. 5a shows a structure of an article of furniture 2 having a support device 1. The furniture flap 21 mounted to the hinged connection 13 of the support device 1 is in a completely closed position in the configuration shown in FIG. 5a.
(21) In this case, the support device 1 is advantageously arranged in an upper region of the furniture carcass 20, for example at a side wall or a top panel, and is mounted by the housing 10. As shown in FIG. 5a, the support device 1 is disposed substantially completely in the interior of the internal space 22 of the article of furniture 2, defined by the furniture carcass 20. By the mechanical drive 14 (which is not visible from the exterior), the furniture flap 21 can in this case be held in the closed position with a force which can be easily overcome by a user.
(22) FIG. 5b shows a configuration of an article of furniture 2 having a support device 1 with a partially upwardly pivoted furniture flap 21. In this intermediate position of the support device 1, the first support arm 11 and the second support arm 12 are disposed in overlapping relationship which is gap-free laterally with respect to the direction of movement of the support arms 11, 12, this being achieved by the second support arm 12 in this and in any other position of the support device 1 being partially arranged within the cavity afforded by the profile of the first support arm 11. It can already be seen in this position of the partially opened furniture flap 21 that the possibility of a user laterally reaching into the internal space 22 defined by the furniture carcass 20 of the article of furniture 2 is not impeded by additional control elements projecting out of the furniture carcass 20. In addition, the mechanical drive 14 which is not visible from the exterior can assist with or also actively drive the opening or closing movement of the furniture flap 21. In addition, the furniture flap 21 can be held in an open position by the mechanical drive 14, with a force which a user can easily overcome. An article of furniture 2 having such a support device 1 for a furniture flap 21 is distinguished by convenient, intuitive and safe operability, while taking up a small amount of space and being easy to fit in place.
