The leg 2G can have a blocking spring that snaps into a corresponding recess of the individual socket 17 in order to ensure the correct orientation of the foot 21. The legs 2 八 eight feet 21 are preferably similar to each other and of equal length. The four legs 20 on the high chair meet up to a point on the seat 4. It can be inferred from Fig. 1 that the cover member 3 is mounted on the bottom side of the chair unit at the area of the wall 6 and the step 5 for screen off a space 31 therebetween. A detachable locking device 7 is attached between the lower end portion of the link μ and the cover member 30 attached to the chair unit 2, as shown in more detail in Figs. 4 and 5. Accordingly, it can be seen that the cover member % has a substantially vertical wall 32 having an opening 33 for a guide track 40, a guide track 疋 passing - a bearing W journaling having a substantially horizontal axis At the lower end portion of the link 15, the locking unit 44 is journaled to the lower portion of the link 5 by a bearing 4i having a horizontal axis. A locking unit 44 is journaled to the guide rail 40, for example, the journal engages the axis of the surrounding bearing 41. The free end portion 47 of the locking soap element extends through the opening 33 of the wall 32 as the rear pair of legs extends. A spring 7 201034603 46 is shown placed between the guide track 4〇 and the locking unit 44. Alternatively, the locking unit, in its own right, elastically bends the support 43 displayed on the guide track 4A to achieve the function of the displayed spring 46. It is further shown that the locking unit has an abutting surface (the abutment s oil is in the form of a m-type 'when the rear leg is extended, the extension position of the locking unit' cooperates with the upper edge portion of the opening π 33 to avoid the rear seat A retraction or folding of the pair of feet. By rotating the locking unit 44 toward the guiding track 40, the abutment surface 45 can pass through the opening 33. The locking unit has a tip end 49 that snaps behind the wall 32. In the region below the opening 33. The cover and the ancient-Schöne, τ complex have a substantially horizontal bottom unit 37 having a guide cam 38 for the lower end of the tip 49. The direction manually applies pressure downwardly against the locking unit 44, which will approach the guiding track 4() such that the abutment surface 45 of the locking unit, along with the guiding track 4(), can be removed through the opening 33, Therefore, during the movement into the space 31, the lower edge of the guide rail 40 and the upper side of the locking unit 44 are slidable against the opening 33 below the respective upper edge. Near the fine return position of 15, the tip 49 will Move to the guiding cam 38 益«铷>58 and the receiver quickly enters a recess 51' as shown in Fig. 5. The slanting mask is sharp from the ^m-h-month display. An end surface 39, which is turned toward the pointed tip & | 7n|, the side of the abutment M that faces the abutment 54. These surfaces are inclined with respect to the longitudinal direction of the guide track and Further, the guiding track 4〇 is flexibly bent and configured. The wood i is provided by a user who wishes to fold the rear connecting rod 15 together with the rear leg 20 toward the display end: the end position of the extension of FIG. The user must apply a relatively large force in the longitudinal direction of the guide track 40 so that the tip 49 leaves the recess 5 1 , 201034603, and then the movement away will occur abruptly. The user can of course not stop applying The force, but will accelerate the connecting rod 15 together with the leg 20 and the guiding track 40 such that the momentum becomes sufficient to reliably overcome between the locking unit 44 and the guiding track 40, respectively, against the opening 33 The friction between the upper and lower edges, and the matching surface of the locking unit 45 The ground is biased to the obstructed position through the opening 33 and under the influence of the spring 46. The spring biased locking unit 44 of course also provides a childproof lock that prevents the link 15 from being associated with the rear leg 2〇Inadvertent folding into the retracted position.
