First up Fig. 1 and 1a to 1g reference, in which the basic structure of an embodiment of the highchair according to the invention is explained. The generally designated 1 high chair has a foot part 2 and a seat member 4, which are rotatably and height-adjustable connected to each other by a gas pressure spring 6 arranged therebetween.

The foot part 2 is constructed in the illustrated embodiment substantially of a ring 8 made of bent metal tube and a fixedly connected cross member 10 made of plastic, on the center of a holding part 12 is arranged with a cylindrical receiving opening 14 for receiving a lower end portion of the gas spring 6.

The seat member 4 is constructed in the illustrated embodiment substantially of a seat 20 with seat pad 22 received therein, wherein the seat shell 20 is held laterally on two approximately quarter-circle curved support arms 24. The support arms 24 are connected to one another at a connection part 26, which at the same time serves to connect to an upper end section of the gas pressure spring 6. A footrest 30 is releasably secured to the seat pan 20.

At upper end portions of the support arms 24, a table 32 is further releasably attached, from which a safety support 34 extends down to a front edge of the seat 20 and is detachably connected thereto.

FIGS. 2 and 3 explain the height adjustment of the highchair 1 more in detail. From the gas spring 6 is at the upper end portion of an actuating projection 40th in front ( Fig. 2a ), which in a depressed state ( Fig. 3a ) a heights -bzw. Length adjustment of the gas spring 6 allows. For this purpose, an acting on the actuating projection 40 angled pressure element 42 is provided which rests with a horizontal central portion 44 on the actuating projection 40 and has two obliquely downwardly angled end portions 46. On each support arm 24, a control element 48 is slidably disposed and connected to one end of a cable or Drahtzugs 50, which is connected at its other end in the region of the pressure element 42 each with a wedge-shaped sliding member 52.

When both controls 48 are simultaneously pulled up, as in Fig. 3 indicated by arrows 54, the sliding members 52 are pulled by the wire 50 toward the central portion 44 of the pressure element 42 to each other and thereby press, because they are supported in the region of its top on a flat guide surface 56, the pressure element 42 down (Arrow 58).

Through the use of two separate acting wire 50 and an angled pressure element 42, a two-hand safety operation is formed, which prevents the height adjustment is undesirably operated by an infant located in the child seat (operation of only one wire train is not enough).

FIGS. 2 and 3 In addition, the holder of the upper end portion of the gas spring 6 in the connecting part 26 of the seat member 4. In the connecting part 26 are arranged two spaced sleeve-like receiving elements 60 whose inner diameter corresponds to the outer diameter of the gas spring 6, and provided with a handle fastening screw 62nd can be tightened laterally against the gas spring 6 to produce a tension and fixation.

4 and 5 basically explain the possibility to pivot the seat member 4 and the seat 20 about a horizontal transverse axis 70 and adjust in this way the inclination of the seat pan. For this purpose, a manually operable actuator 72 is arranged on the rear side of the seat shell.

Fig. 6 and details after Fig. 6a to 6d explain the locking of the seat at a desired inclination. The seat shell 20 is provided with two lateral, the transverse axis 70 fixing axle pins 74, in which longitudinal grooves 76 are formed. On each journal 74, a rotary locking member 78 is disposed axially displaceable and engages with radially inwardly directed projections in the longitudinal grooves 74 so that it is rotatably connected to the journal 74. The rotation locking member 78 is further provided with locking teeth 80 with which it can positively engage with complementary locking projections or teeth formed on the inside in a bearing sleeve 82, which in turn is fixedly connected to the respective support arm 24. Between the rotary locking member 78 and the bearing sleeve 82, a helical return spring 84 is disposed on one side and a rotary cam member 86 on the other side, which is provided with three wedge-shaped rising cam or guide surfaces 88 which are arranged distributed over its circumference. The rotary locking member 78 is provided in a manner not shown with counter-surfaces which cooperate with the cam 88.

The rotary cam member 86 is rotatably mounted on the journal 74 and connected to the operating member 72 by a suitable actuating means, in this example by a wire 90. Conveniently, the in Fig. 6a to 6d shown Drehverriegelungsanordnung in the same way on both sides of the seat 20 available.

Upon actuation of the control element 72 in the direction of arrow 92, the rotary cam member 86 is rotated by a predetermined angular amount and thereby displaces the rotatably guided on the journal 74 rotary locking member 78 against the force of the return spring 84 outward in the direction of arrow 94. The locking teeth 80 of Rotary locking member 78 thereby out of engagement with the locking teeth of the bearing sleeve 82, so that the seat shell 20 can be pivoted freely about the transverse axis 70. Upon reaching a desired inclination, the control element 72 is released, and the return spring 84 brings the rotary locking element 78 again in locking engagement with the bearing sleeve 82, so that the axle journal 74 and thus the seat shell 20 is held non-rotatable relative to the support arms 24.

Fig. 7 and 7a to 7f explain how the seat member of the highchair is held relative to the foot part about a vertical axis 96 rotatable and lockable. To this Purposes is provided in or on the holding part 12 of the foot part 2, a C-shaped clamping ring 100, whose opposite ends can be clamped by means of a toggle lever or Übertodpunkthebelanordnung towards each other. The toggle lever assembly is constructed in the illustrated embodiment of a clamping lever 102 and an actuating lever 104 which are pivotally connected to the clamping ring 100 and each other.

In the in Fig. 7a, 7b, 7d, 7e illustrated position, the clamping ring 100 is firmly clamped on the lower end portion of the gas spring 6, so that these and the seat member 4 can not rotate relative to the foot part 2. If the operating lever 104 is released ( Fig. 7c, 7f ), the clamping ring 100 releases the gas spring 6, and the seat member 4 can be rotated.

A circumferentially slidable safety slide 106 takes its spring loaded in Fig. 7a, 7d illustrated initial position in which the operating lever 104 can not be engaged behind, so that accidental operation is prevented by children. Only a return movement of the safety slide 106 in the direction of arrow 108 (FIG. Fig. 7b, 7e ) allows opening of the operating lever 104.

Fig. 8 and 8a to 8d explain the attachment of the table 32 to the support arms 24. Like Fig. 8c shows, the table 32 has two hook-shaped fastening lugs 120, which are provided on the inside with two locking projections 122 and, opposite this, with a detent not shown, the position of which is indicated by 124. The bearing sleeves 82 held at the upper ends of the support arms 24 are provided on the outside with groove-like depressions 126, into which the fastening lugs 120 are to be inserted.

In each bearing sleeve 82 is a spring-loaded locking element 130 ( Fig. 8b ), which carries a latching projection 132 and can be actuated from the outside with a push-button 134, so that the latching projection can be moved back into the bearing sleeve 82.

When attaching the attachment lugs 120 on the bearing sleeves 82 and in the recesses 126 engage the locking projections 122 in corresponding recesses (not shown) in the bearing sleeve 82, and the locking projections 132 engage in the locking recesses 124, so that the table is held firmly on the support arms 24. To release the push buttons 134 are actuated, so that the locking projections 132 pull back and the fastening lugs 120 can be solved.

Fig. 9 and 9a to 9d explain the attachment of the safety support 34, which can be fixed with a locking foot 140 in a locking receptacle 142 of the seat. As Fig. 9d shows, in the illustrated locked initial position spring-biased push-button element 144 is provided, which protrudes with two lateral end portions 146 of the locking foot 140. A trained in the locking receptacle 142 inlet bevel 148 with a latching recess 150 disposed behind it allows automatic locking of the locking foot when inserted into the locking receptacle 142. By depressing the push button member 144, the end portions 146 are released from the Einrastvertiefungen 150, and the locking foot 140 can from the locking receptacle 142 pulled out.

Since the table 32 remains independent of the set angle of inclination of the seat horizontally, the safety support 34 is expediently formed variable in length, which is achieved in the present case by a telescopic design. Alternatively, an elastic material could be provided.

The footrest 30 is also formed variable in length, expediently by two interlocking, telescopically displaceable parts. Again, a clamping or locking means for fixing a selected length may be appropriate. <B><u> REFERENCE LIST </ u></b> 1 Highchair 106 safety slide 2 footboard 108 arrow 4 seat element 120 mounting boss 6 Gas spring 122 locking projection 8th ring part 124 latch recess 10 cross section 126 deepening 12 holding part 130 locking element 14 receiving opening 132 catch projection 20 seat 134 push-button 22 seat cushion 140 Snap-on foot 24 Beam 142 latching receptacle 26 connecting part 144 Push-button element 30 footrest 146 end 32 table 148 run-in slope 34 safety support 150 clicking depression 40 operating projection 42 pressure element 44 middle section 46 end 48 operating element 50 Drahtzug 52 Slide 54 arrow 56 guide surface 58 arrow 60 fixing screw 70 transverse axis 72 operating element 74 journal 76 longitudinal groove 78 Rotary locking element 80 locking tooth 82 bearing sleeve 84 Return spring 86 Rotary cam member 88 cam 90 Drahtzug 92 arrow 94 arrow 96 vertical axis 100 clamping ring 102 clamping lever 104 actuating lever
