Definitions

• the invention relates to a collapsible highchair according to the preamble of claim 1.
• the present invention provides a highchair which, in fact, has a high level of safety, can be operated completely easily and quasi “foolproof” and requires only a surprisingly small amount of storage space in its transport position.
• the highchair according to the invention has legs which are articulated on a central body offset in the circumferential direction and which can be pivoted jointly from one position to the other without problems via a positive link arrangement even when only two legs are gripped and actuated. Since at least five legs are provided, with an upper support and holding section, on which the " high chair seat element is suspended, between the two leg openings, a high level of safety is achieved.
• the adjustment kinematics of the highchair according to the invention appears to be particularly surprising. Because when the legs are swiveled into the space-saving transport position, the upper cranked support and holding sections of the legs are attached to the NEN, the high chair seat element is suspended, in plan view, pivoted in the manner of a swirl movement in such a way that the ends of the carrying and holding sections run past one another, and the similarly suspended high chair seat element, which consists, for example, of plastic or fabric elements, also automatically is folded by twisting and twisting within itself.
• FR 1 243 953 An arrangement for collapsible chairs is known per se, for example from DE 24 59 821 AI, US 2 798 536 or, for example, FR 1 243 953.
• the stand devices presented there comprise four stand legs articulated on a central body offset in the circumferential direction.
• FR-PS 1 243 953 only a fabric-like seat cloth can be folded with the previously known kinematics, the ends of the carrying and holding sections, which are slightly cranked, more or less close to the vertical central axis of the whole Chair device come to rest in the final transport position.

• Figure 4 a children's high chair
• Figure 5 a plan view of the stand device.
• the stand device is explained in more detail below on the basis of a high chair for children, the stand device being shown in FIG. 1 without the actual high seat anchored at the upper end.
• the exemplary embodiment comprises a standing device with six standing legs 1, which extend radially by one each on a central body 3 lying on the vertical central axis to the vertical central axis lying horizontally aligned adjustment axis 5 are pivotable.
• the central body 3 can consist of a tubular or nut-shaped connecting piece, the adjustment axes 5 being formed, for example, by screw bolts or by a rivet connection, the portions of the pivot axes 5 protruding into the interior of the central body 3 preventing them from accidentally slipping out of their anchoring are secured. In particular, even when using a riveted joint, a slight pivoting play can be quite desirable.
• the supporting legs 1 are provided at their lower end with foot sections 1 'and with support and holding sections 1 "which project upwards beyond the respective adjustment axis 5 and which also have a
• cranks 7 'lying above and the cranks 7' 'lying below can be designed such that, in the standing position shown in the figures, the cranking sections are approximately vertically aligned, at least with respect to the sections of the standing legs 1 which are more inclined therebetween.
• the legs 1 are pivoted on the central body 3 all around the adjustment axes 5, whereby in the set-up position a locking of the stand device can be ensured in that one leg 1 rests closest and a further pivoting in the open position thereby is blocked.
• additional intermediate elements for example fastened to the central body 3, can also be provided between each of the two supporting legs.
• a positive guidance is provided according to the invention, which automatically swivels in or out of all other legs only when, for example, two opposite legs are actuated.
• This positive link arrangement 9 consists of a coupling body 11 and adjusting core 13.
• the coupling body 11 is arranged above the central body 3 and, as can be seen from the schematic representations in FIG. 3 using only two opposite supporting legs 1, and for example, also tubular or annular.
• Articulated axes 15 are offset on the outer circumference, by means of which an adjusting link 13 is articulated, the other end of which is in turn fastened to the leg 1 assigned to it via an intermediate articulated axis 17.
• the distances between the articulation axis 15 on the coupling body 11 to the intermediate articulation axis 17 on the associated supporting leg 1 correspond approximately to the length from this intermediate articulation axis 17 to the adjustment axis 5 on the central body 3.
• Each of the supporting legs 1 is connected to the common coupling body 11 via an adjusting link 13 of this type, preferably the articulation axis 15, the intermediate steering axis 17 and the adjusting axis 5 associated with each supporting leg 1 being oriented at least approximately parallel to one another.
• the corresponding link section of the respective adjustment link 13 is completely guided through the tubular or strut-shaped support leg 1 to form the intermediate link axis 17 and protrudes briefly on the opposite side.
• FIG. 3 On the basis of the structure shown schematically in FIG. 3 for two legs 1, it can be seen that only when pivoting, for example, the leg 1, which runs from top left to bottom right in FIG. 3, from the standing position shown there according to the arrow representation 19 via the
• Adjustment 13 automatically the coupling body 11 is raised. This lifting movement of the coupling body 11 is transmitted via the adjusting link 13 on the right in FIG. 3 only to the supporting leg coupled to it, which is then also pivoted toward the vertical central axis until it also assumes the closed position.
• a longitudinal pin 21 serving as a guide can also be attached, for example on the coupling body 11, pointing downwards, as shown in broken lines in FIG. 3, which projects through the central opening in the central body 3.
• a reverse fixed arrangement of the longitudinal pin 21 on the central body 3 is also conceivable, so that in this case the coupling body 11 can be displaced on the longitudinal pin 21 projecting through it.
• the first-mentioned variant is preferred when using a longitudinal pin 21, since in this case the top of the coupling body 11 can simultaneously serve as a support surface, for example for the seat surface of a highchair - which will be discussed later.
• the positive link arrangement 9 can also be provided below the central body 3 in addition or as an alternative to FIG. 3.
• the distance between the pivot axes 15 and thus the diameter of the coupling body 11 can be greater than the corresponding position of the adjustment axes 5 or. the diameter of the central body 3.
• the construction of the stand device explained above also applies, for example, to five legs or also to seven or even more.
• the individual opposite or approximately opposite legs can be marked with the same color or with the same color dots, for example in the foot area, in order to be able to better identify the grip of opposite legs 1 for folding or swinging apart.
• the upper high chair seat element 23 is hung in the stand device explained above.
• the seat element 23 On the upper carrying and holding sections 1 "shown in FIG. 1, the seat element 23 is suspended, which is provided with corresponding vertical pockets 25 which are closed at the top and into which the carrying and holding sections 1" engage.
• the lower fabric or plastic flaps of the seat element 23 can be sewn or welded to a floor and, for example, can be firmly anchored to the coupling body 11 by means of a holding plate (not shown in the drawings).
• a holding plate can, for example, be screwed onto the coupling body 11 from below.
• the coupling body 11 also serves as a support element for the seat surface.
• Complementary can also be a removable, for example at least along one axis collapsible in the seat element. a certain stiffening seat element can be inserted.
• a high level of stability is finally achieved in that an upper support and holding section 1 "
• Main leg 1 lies between the two leg lead-through openings 29. This significantly improves stability compared to previous solutions.
• Rear support and Ilalt sections 1 "can be extended to form a backrest.
• FIG. 5 shows schematically in plan view how the upper cranked carrying and holding sections 1 "are moved along the arrows 27 when folded into the transport position. From this it can be seen that when the highchair seat element 23 is suspended, this fabric-like seat element in FIG This is possible since the upper tips or ends of the carrying and holding sections 1 "pivot on the central axis and thus past one another when being adjusted from the standing to the transport position become .
• the stand device according to the invention only requires very few different components anyway, namely a specific embodiment for a stand leg 1, an adjusting link 13 and a central body 3 and a coupling body 11.
• By self-locking in the opened stand device by mutual jamming of the corresponding spar brackets cuts of the legs 1 is also ensured that even when using the stand device, for example for a high chair, the actual high chair seat element 23rd is not subjected to tensile stress, since in a final standing position the individual standing legs are blocked against each other and thus a further opening movement of the standing legs is not possible.
