Description

The invention relates to furniture fittings for sitting and / or lying, which is formed for the movement of two furniture parts relative to each other.

The invention aims to create such accessories that can be used largely universally and, moreover, is simple and easy to maintain.

This is achieved due to the fact that two levers are mounted with a possibility of rotation on the cross-member fixed on one furniture part, and the opposite ends of which are pivotally mounted on the other furniture part, and the movement of rotation of both levers is limited by stops and an additional lever is connected to each rotary lever which is directed in the opposite direction, but at an angle not equal to 180º.

With the fittings made according to the invention, one or another piece of furniture can be raised or lowered. This does not require complex parts such as articulated four-link, scissors, etc. and when turning the levers no dead zones arise.

According to a further feature of the invention, it is envisaged that the pivoting levers or additional levers on one side are connected by a connecting lever in order to ensure synchronous movement of the spaced apart levers.

In a particularly suitable embodiment of the invention, one of the two levers is mounted in an elongated hole with the possibility of movement in height and its continuation interacts with the stop through which it rises. To both parts of the furniture moved relative to each other, you only need to raise the lever in the elongated hole through the emphasis, which previously blocked it.

The accessories according to the invention of furniture for seating, which can be transformed into sleeping furniture, moreover, its seat cushion with the help of furniture made from a sitting position to the one lying underneath it, characterized in that on the inner side of the two side furniture racks are fixed one cross-section with rotary levers and the ends of the levers pivotally mounted on the frame of the seat cushion.

The fittings according to the invention can be used in a new type of furniture in which the seat cushion frame is fixed and the armrests are movable in height relative to this frame. Therefore, the armrests can lower to the height of the seat cushion so that a large, uniform surface is formed.

Below the invention is described in more detail using the examples shown in the drawings; however, it is not limited to these examples. The following are shown:

FIG. 1 - Furniture for seating according to the invention, a side view in partial section;

FIG. 2 - Section along the line II-II in FIG. fourteen;

FIG. 3 is a schematic view of one side of the furniture according to the invention;

FIG. 4 - Accessories on one side according to the invention;

FIG. 5 - A new type of furniture for sitting with armrests and a related part;

FIG. 6 - Furniture of FIG. 5 with armrests down;

7 is a General view of the accessories according to the invention;

FIG. 8 - Sectional view of the furniture of FIG. 5.

According to the drawings, a cross member 3 is mounted above the recess 1 of the side strut 2. Swivel arms 4 are located on the cross member 3, the opposite ends of which are articulated on the seat cushion frame 5. The support in this case occurs through the screws 6, respectively, of the rod 7.

On the rear side of the cross member 3 on the axes 8 of the pivoting levers 4, additional levers 9 are fixed, which are oriented in the opposite direction, but at an angle not equal to 180º. These additional levers are connected by a connecting lever 10.

As shown in FIG. 1, 2, 3 in the raised position of the seat cushion frame 5, and in the lowered position shown in FIG. 4, the rotation of the levers 4 is limited by the stops 11.

The furniture for seating according to the invention has two side racks 2, with the furniture in question in both racks 2. In this case, the rod 7 connects two opposite pivoting levers 4. Due to this, the rotations of the levers 4, respectively, of the additional levers 9 on both sides of the frame 5 of the additional pillow are synchronized.

As shown schematically in FIG. 1, a furniture part 12 may be provided with a cushion which, when the seat cushion is lowered, complements the furniture surface. With the seat cushion raised, the furniture part 12 with the cushion slides under the seat cushion.

Numerous changes are possible within the scope of the invention. Thus, the fittings may not be located in the recess of the side pillars 2, although this has advantages with respect to the gap between the frame 5 of the seat cushion and the side pillars 2.

In FIG. 5 and 6 show a new type of furniture in which the seating part 20 is surrounded on three sides by a fence consisting of two armrests 21 and a connecting part 22. Elements 21 and 22 have the same height as the seating part 20 and can be moved using the fittings according to the invention in height, thus moving from the position of FIG. 5 to the position of FIG. 6.

In this exemplary embodiment (Figs. 7 and 8), the cross-pieces 23 of the fittings are located in the recesses of the seating part 20, and the levers 24 and 25 act on the armrests 21. The lever 25 rests on the pivoting arm 26. At its lower end, the arm 25 has a protrusion 27, which in the turned upward position of the lever 25 interacts with the stop 28.

The levers 24, 25 are fixed on the axes 29, 30, which at their opposite ends carry additional levers 31, 32. Both additional levers 31, 32 are connected to each other by a connecting lever 33. The additional lever 31 is provided with a continuation 34, on which the spring 25 acts.

Each cross member 23 has an elongated hole 36 in which the axis 30 moves. The lever 25 can thus be lifted and pivoted through the stop 28 until the lever 24 reaches the stop 37. Due to this, the armrests 21 are lowered to the height of the seating part 20.
