Description

The invention relates to a piece of seating furniture, in particular a high chair for children according to claim 1.

High chairs for children (children's chairs) have been known for a long time and in various designs. Typically, such high chairs comprise a frame with a pair of front chair legs and a pair of rear chair legs (or alternatively, for example, only two chair legs that are appropriately extended at their lower end to ensure stability) and a seat with a seat and a backrest. Additional elements can include armrests, a footrest, a storage area ("tray") and the like. The frame (with or without a seat) can optionally be foldable to enable a use position and a (more compact) folded position.

The seat may be in a fixed position relative to the frame or may be adjustable in height, whereby either the entire seat is adjusted or individual components such as the seat and/or the backrest and/or the footrest (which may then be adjusted independently of each other). In the prior art, it is also common for (in the case of height-adjustable high chairs) a certain number of predetermined positions (height positions) are made possible for the adjustable components, for example by forming holes at suitable locations on the frame and (retractable) pins on the component to be adjusted.

An adjustable child seat is made of DE 690 09 806 T2 known.

According to DE 690 098 06 T2 Two pins (one on each side of the high chair) are provided for height adjustment, which can take on different, discrete positions in a guide track, so that the high chair can be adjusted in height. In principle, similar solutions are available from

US 5 238 292 A as well as US 4 722 570 A known. In US 5 238 292 A Locking elements are provided which can be engaged with corresponding ribs so that the height can also be adjusted.

US 4 722 570 A describes hook elements that can interact with locking elements, also to enable discrete height adjustment. Overall, these solutions in the state of the art are considered to be relatively complex in terms of construction and handling and, in particular, relatively inflexible.

It is therefore an object of the invention to propose a piece of seating furniture, in particular a children's chair, preferably a high chair for children (children's chair) with an adjustable support device for supporting a part of the body of a child, wherein an adjustment of the height should be possible in a simple and in particular flexible manner.

This object is achieved by a piece of seating furniture, in particular a high chair according to claim 1.

Further embodiments of the invention emerge from the subclaims.

The seating furniture, in particular the high chair, can have a frame, possibly with a pair of front chair legs and a pair of rear chair legs (or alternatively, for example, only three or only two chair legs, which may be extended at their lower end to ensure stability) and a seat with a seat and optionally a backrest. Additional elements can include armrests, a footrest and/or a storage area ("tray"). The frame (with or without a seat) can be foldable if necessary to enable a use position and a (more compact) folded position.

The invention not only includes a height adjustment (even if the present invention is particularly advantageous for a height adjustment, since it is particularly important here that the child or other objects can be positioned as precisely as possible), but also generally an adjustment of another position of the support device, in particular a depth adjustment (i.e. in particular an adjustment of the support device further forwards or further back). In this respect, in the above and the following, "height adjustment" can be replaced by "height and/or depth adjustment" wherever the orientation of the respective adjustment option is not important (or at least not crucial) (as is the case when using gravity, for example). Furthermore, information such as "up" or "down" can then be replaced by "forwards" or "down".

Overall, in contrast to the prior art, not only discrete (predetermined) positions of the height adjustment can be achieved, but a continuous adjustment can be carried out. This also reduces material and manufacturing costs, since separate elements such as locking recesses or the like do not necessarily have to be present for the individual predetermined positions (as in the prior art). Overall, a height adjustment device is made possible that allows a continuous height adjustment of an adjustable component and that has a certain setting position can also be held securely, while at the same time the production costs are comparatively low.

In the following description, the same reference numbers are used for identical and equivalent parts.

Fig. 1 shows a high chair 10 with legs 11, a seat 12, a backrest 13, a footrest 14 and a storage area (tray) 15.

The seat 12 and the footrest 14 are (independently of each other) adjustable in terms of their height in relation to the legs 11. The mechanism for adjusting the height is analogous for the seat 12 and the footrest 14, so that only the mechanism for adjusting the height of the seat 12 is explained in detail below.

The seat surface 12 generally comprises a (symmetrical) locking device 20. The locking device 20 has an actuating device (lever) 21 and a stabilizing strut or a housing 27. On each side of the locking device there are also a force transmission device (rod) 23, a spring 24, a contact element 28 (at the end of the force transmission device 23), which can be designed as a pressure plate, and two locking elements 25 or clamping devices 25 (see Fig. 2 and 3 ) is provided.

The spring biases the locking elements 25 against each other in a locked state, whereby these locking elements 25 are brought into engagement with a (corresponding) leg 11 of the high chair 10, specifically with a groove 29 provided there. When the locking device 20 is in a locked state, the actuating device 21 can be designed (at least substantially) parallel to the housing 27 and can optionally form a flush surface with this housing.

The actuating device 21 has a (round) central section 22 and (in the present case two) recesses 22a, wherein in the locked state each recess 22a is in engagement with one of the force transmission devices 23 (rods). The locking elements 25 (on each side) are pivotally mounted on the housing 27 about a common axis 26.

The locking device can be transferred from a locked state to a released state by rotating the actuating device 21 so that the force transmission device 23 is moved outwards (since the force transmission device 23 can then no longer remain in engagement with the recesses 22a). As a result, the contact device (pressure plate) 28, which is arranged at a distal end of the respective force transmission device 23, is also moved outwards and presses against proximal ends of the locking elements 25. Due to this movement, the locking elements 25 pivot about their (common) axis 26 against the tension force of the spring 24 and thus release from the leg 11.

By rotating the actuating device 21 (back to its original position), the spring 24 can pivot the locking elements 25 back so that they are again locked with the leg 11, since in this state the Force transmission device 23 in turn engages with the recesses 22a. As a result, in the event of an upward force or a downward force, one of the locking elements (clamping devices) 25 can come into clamping engagement with the corresponding groove 29 and thus prevent the seat surface 12 from being moved in the direction of the force.

Fig. 4 shows a side view of individual elements of a high chair according to the invention. This can be Fig. 1 to 3 be trained so that Fig. 4 also as an illustration of further details of the high chair according to the Fig. 1 to 3 can be viewed. In the Fig. 1 to 3 However, the sliding plate 30 is not shown. This sliding plate 30 can optionally be used in the embodiment according to the Fig. 1 to 3 be provided (or not). Conversely, in the Fig. 4 to 7 the sliding plate 30 is shown. However, this sliding plate in particular is in the embodiment according to the Fig. 4 to 7 only optional.

In the Fig. 4 to 6 It can be seen that by rotating the actuating device 21 the locking elements 25 are pushed into the groove 29 (see Fig. 4 ) or led out (by swiveling, see Fig. 5 and 6 ). The position according to Fig. 4 corresponds to the position according to Fig. 2 .

Furthermore, in Fig. 4 to 7 the already mentioned plate 30 can be seen.

The plate 30 (see also Fig. 7 ) has a slot 31 through which the sliding elements 25 (see Fig. 4 ) can penetrate. The plate 30 moves when the actuating device 21 moves (upwards or downwards), so that the plate 30 enables reliable guidance of the height adjustment. The plate 30 therefore moves in the groove 29 (when the actuating device moves upwards or downwards). According to the design, the locking (arresting) is created between the locking elements 25 and the groove 29. The plate 30 has a particularly reinforcing or stabilizing effect and improves guidance in the groove. The plate preferably has no (or at best an insignificant) influence on the locking (arresting) as such (however, in a potential alternative embodiment this can also be different).
