    Abstract

    A seating and/or lounging furniture includes: a seat frame; an extendable footrest; a footrest frame, which is displaceable on the seat frame, and on the front end of which the footrest is held movably, pivotable around a pivot axis; at least one drive for displacement of the footrest frame along a displacement distance relative to the seat frame; and at least one operating rod for swinging the footrest in and out, around the pivot axis, wherein the operating rod is connected at one end to the footrest, while the other end of the operating rod is connected to the seat frame by means of a hinge mechanism, so that displacement of the footrest frame over at least 60%, preferably over at least 80%, and extremely preferably over at least 90% of the displacement distance causes a simultaneous pivoting movement of the footrest about the pivot axis.

    [0022] FIG. 4 shows a side view of the position according to FIG. 3c as seen from the outside,

    [0023] FIG. 5 shows a three-dimensional diagram of an actuating mechanism according to a second exemplary embodiment in which the footrest has, in addition to a main supporting element, also an additional supporting element connected thereto with an articulated connection,

    [0024] FIGS. 6a-6c show side views of the actuating mechanism according to FIG. 5 in various positions of the footrest.

    [0025] The seating and/or lounging furniture illustrated in FIG. 1 is for example an armchair or a sofa. In the exemplary embodiment shown here, the seating and/or lounging furniture has a seat 1, a backrest 2, an armrest 3 and a footrest 4, wherein the footrest 4 is shown in the extended state in FIG. 1.

    [0026] FIG. 2 shows an actuating mechanism 5 for extending and retracting the footrest 4. It has a footrest frame 6 consisting of two rods 6a (only one of the two rods is shown in FIG. 2) and at least one crossbar 6d connecting the two rods 6a. This forms an essentially H-shaped footrest frame 6, which is mounted displaceably in the area of its two opposing rods 6a. In the exemplary embodiment illustrated here, each rod 6a on the seat frame 7 is mounted by means of two guide rolls 8, 9 arranged above the rod 6a and one guide roll 10 arranged below the rod, so that the footrest frame 6 is guided in a stable manner and is displaceable along the extent of the rods 6a on the seat frame 7.

    [0027] The footrest frame 6 is displaced by means of a drive 11, which is designed as a linear motor and is connected at one end to a crossbar 12, which is firmly connected to the seat frame 7, and to the crossbar 6b of the footrest frame 6 at its other end. Therefore, actuation of the drive 11 results in a parallel displacement of the crossbar 6b relative to the stationary crossbar 12 of the seat frame 7 after the crossbar 6b has been firmly connected to the rods 6a, so that actuation of the drive results in displacement of the footrest frame 6 along a displacement distance, which is predetermined by the guide rollers 8-10. However, a slide bearing or any other suitable type of bearing could be provided instead of guide rollers 8-10, for example.

    [0028] The additional embodiments of the actuating mechanism 5 are described in greater detail below with reference to FIG. 2 and the various positions of the footrest illustrated in FIGS. 3a to 3c. FIG. 3a shows the retracted position of the footrest;

    [0029] FIG. 3c shows the extended position and FIG. 3b shows an intermediate position. The maximum displacement distance of the footrest frame 6 is thus indicated by a comparison of the FIGS. 3a and 3c, each of which illustrates the end positions of the footrest frame 6.

    [0030] In this exemplary embodiment, the footrest 4 has a main supporting element 4a which is held movably at the end of the rod 6a to pivot about a pivot axis 13. The pivoting movement of the footrest 4 which is synchronized with the displacement of the footrest frame 6 is implemented with an operating rod 14, which is connected with an articulated joint to the footrest 4 at one end and/or to the main supporting element 4a at a hinge point 15 (FIG. 2a). At the other end of the operating rod 14, an articulated joint mechanism 16 is provided, with which the operating rod 14 is connected to the footrest frame 6 as well as to the seating frame 7.

    [0031] The articulated joint mechanism 16 comprises a first joint lever 16a, which is connected to the footrest frame 6 at a middle joint position 16b in an articulated connection. The operating rod 14 is connected to a first outer hinge point 16c of the first joint lever 16a at its end facing away from the footrest 4. At the other end of the first joint lever 16a, a second outer hinge point 16d is provided, at which the first joint lever 16a is connected to a second joint lever 16e in an articulated connection, wherein the second joint lever 16e is connected to the seat frame 7 in an articulated connection at a third hinge point 16f.

    [0032] The positions of the individual joint levers of the articulated joint mechanism 6 with respect to the footrest 4 can be seen in three different positions of the footrest 4 in FIGS. 3a to 3c. FIGS. 3a to 3c show a side view of the actuating mechanism 5 from the center of the seating and/or lounging furniture, as seen from the outside. It can be seen in FIG. 3c in particular that operating rod 4 and rod 6a of the footrest frame are designed to be parallel and overlapping. When the seating and/or lounging furniture is seen from the outside (see FIG. 4), the operating rod 14 is covered completely by the rod 6a of the footrest frame, resulting in a particularly slender construction. The footrest frame 8 is arranged to be guided by means of the guide rollers 8-10 inside the seat frame 7, so that injury of the user can be ruled out. Only in the area of the folding movement of the footrest 4 on the forward end of the operating rod 14 are suitable covers and/or safety measures provided to prevent injury to the user.

    [0033] FIG. 5 shows a second exemplary embodiment of the invention which corresponds essentially to the exemplary embodiment according to FIG. 2. There is only one difference in the area of the footrest 4, which also discloses, in addition to the main supporting element 4a in the exemplary embodiment according to FIG. 5, an additional supporting element 4b connected thereto in an articulated connection. As can be seen in particular from FIGS. 6a to 6c, the main supporting element 4a and the additional supporting element 4b are connected to each other by an articulated point 4c.

    [0034] The operating rod 14 is still connected to the main supporting element 4a via the hinge point 15 in an articulated connection. However, the operating rod 14 is still connected to the additional supporting element 4b by means of a connecting arm 4d in an articulated connection. Displacement of the operating rod 4 relative to the footrest frame 6 thus causes not only a pivoting movement of the main supporting element 4a about the pivot axis 13, but at the same time also causes the additional supporting element 4b to be pivoted outward by means of the connecting arm 4d at the same time. Due to this construction, the footrest 4 may be designed to be somewhat larger and is also shown in the retracted condition of the footrest, so that the footrest is also folded away, so that it is much more compact and therefore can be placed beneath the seat 1 more easily and in a more aesthetically attractive manner.
