Description

(1) In the following, the invention is described on the basis of an exemplary embodiment, which is explained in more detail on the basis of the figures. In the figures:

(2) FIG. 1 shows a schematic front view of a high chair according to the invention with partially transparently illustrated areas;

(3) FIG. 2 shows individual elements of the high chair according to FIG. 1;

(4) FIG. 3 shows individual elements of the high chair according to FIG. 1 in an oblique view;

(5) FIG. 4 shows individual elements of a high chair according to the invention in a side view and a first position;

(6) FIG. 5 shows the elements according to FIG. 4 in a side view and a second position;

(7) FIG. 6 shows the elements according to FIGS. 4 and 5 in the position according to FIG. 5 and an oblique view; and

(8) FIG. 7 shows individual elements of the high chair according to FIGS. 4 to 6.

(9) In the following description, the same reference numbers are used for identical and identically acting parts.

(10) FIG. 1 shows a high chair 10 with legs 11, a seating surface 12, a backrest 13, a foot rest 14 and a tray 15.

(11) The seating surface 12 and the foot rest 14 are adjustable (independently of one another) with regards to their height with respect to the legs 11. The mechanism for height adjustment is analogous for the seating surface 12 and the foot rest 14, so that in the following, only the mechanism for the height adjustment of the seating surface 12 is explained in detail.

(12) The seating surface 12 generally comprises a (symmetrical) locking device 20. The locking device 20 has an actuating device (lever) 21 and a stabilization strut or a housing 27. A force-transmission device (rod) 23, a spring 24, a bearing element 28 (at the end of the force-transmission device 23), which may be constructed as a pressure plate, and two bolt elements 25 or clamping devices 25 (cf. FIGS. 2 and 3) are provided on each side of the locking device.

(13) The spring tensions the bolt elements 25 with respect to one another in a locked state, wherein these bolt elements 25 are brought into engagement with an (assigned) leg 11 of the high chair 10, actually with a groove 29 provided there. If the locking device 20 is in a locked state, the actuating device 21 can be constructed to be (at least substantially) parallel with the housing 27 and, if appropriate, form a flush surface with this housing.

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

(15) The locking device can be transitioned from a locked state to a released state, in that the actuating device 21 is rotated, so that the force-transmission device 23 is moved outwards (as the force-transmission device 23 can then no longer remain in engagement with the recesses 22a). As a result, the bearing device (pressure plate) 28, which is arranged at a distal end of the respective force-transmission device 23, is moved outwards and presses against proximal ends of the bolt elements 25. Owing to this movement, the bolt elements 25 pivot about their (common) axis 26 counter to the tensioning force of the spring 24 and thus are detached from the leg 11.

(16) Due to a rotation of the actuating device 21 (back into their original position) the spring 24 can pivot the bolt elements 25 back, so that these are in turn locked to the leg 11, as in this state, the force-transmission device 23 is in turn in engagement with the recesses 22a. As a result, in the case of an upwardly acting force or a downwardly acting force of one of the bolt elements (clamping devices) 25 can come into engagement with the corresponding groove 29 and thus prevent the seating surface 12 from being moved in the force direction.

(17) FIG. 4 shows a side view of individual elements of a high chair according to the invention. This may be constructed according to FIGS. 1 to 3, so that FIG. 4 can also be considered as illustrating further details of the high chair according to FIGS. 1 to 3. However, the small slide plate 30 is not illustrated in FIGS. 1 to 3. This small slide plate 30 can optionally be provided (or not) in the embodiment according to FIGS. 1 to 3. Conversely, the small slide plate 30 is indeed illustrated in FIGS. 4 to 7. However, this small slide plate is only optional in the embodiment according to FIGS. 4 to 7 in particular.

(18) One can see in FIGS. 4 to 6, that by rotating the actuating device 21, the bolt elements 25 are forced into (cf. FIG. 4) or are guided out of the groove 29 (specifically by means of pivoting, cf. FIGS. 5 and 6). The position according to FIG. 4 corresponds to the position according to FIG. 2.

(19) Furthermore, the already mentioned small plate 30 can be seen in FIGS. 4 and 7. The small plate 30 (cf. also FIG. 7) has a slot 31, through which the slide elements 25 (cf. FIG. 4) can penetrate. The small plate 30 moves with a movement of the actuating device 21 (upwards or downwards), so that a reliable guidance of the height adjustment is enabled by means of the small plate 30. The small plate 30 is therefore entrained in the groove 29 (in the case of movement of the actuating device upwards or downwards). According to the implementation, the bolting (locking) is produced between the bar elements 25 and the groove 29. The small plate 30 in particular has a reinforcing or stabilizing effect and improves the guidance in the groove. The small plate preferably does not have (or at best has an insignificant) influence on the bolting (locking) (but this may be different in a potential alternative embodiment).

(20) It is noted at this point that all of the above-described parts, considered separately and in any combination, particularly the details illustrated in the drawings, are claimed as essential for the invention. Modifications thereof are familiar for the person skilled in the art.
