High chair with folding legs

Abstract

A high chair ( 1 ) comprising a chair unit ( 2 ), which comprises a seat ( 4 ) and a back rest ( 3 ) attached to the seat, wherein the chair unit ( 2 ) is supported by a front pair of legs ( 20 ) and a rear pair of legs ( 20 ), wherein the rear pair of legs is arranged to be foldable between a support position, in which the pairs of legs are extended from each other, and a storage position, in which the pairs of legs are retracted towards each other. The legs of the rear pair of legs are carried by a link ( 15 ), which is journalled in the in the chair unit ( 2 ) with an upper part for pivotal movement around a horizontal axis. A locking device ( 7 ) is provided in order to allow locking of the link ( 15 ) and thereby of the rear pair of legs in the extended end position of the link ( 15 ).

1 . A high chair comprising a chair unit, which comprises a seat and a back rest attached to the seat, wherein the chair unit is supported by a front pair of legs and a rear pair of legs, wherein the rear pair of legs is arranged to be foldable between a support position, in which the pairs of legs are extended from each other, and a folding position, in which the pairs of legs are retracted towards each other, in that the legs of the rear pair of legs are carried by a link, which is journalled in the chair unit with an upper part for pivotal movement around a horizontal axis, and in that a locking device is provided in order to allow locking of the link and thereby of the rear pair of legs in the extended end position of the link. 
     
     
         2 . The high chair according to  claim 1 , wherein the locking device comprises a guide rail pivotally attached to the link, which guide rail extends through an opening in a wall attached to the chair unit, in that the guide rail carries a locking element that is movable in relation to the guide rail, in that a biasing spring is provided for biasing the locking element to an end position in a direction away from the guide rail, and in that the locking element has an abutment surface facing the wall, which is located adjacent to the wall and outside the edge of the opening, when the link and thereby the rear legs are in the extended end position, and in that the wall opening is arranged to allow the locking element to pass through the opening together with the guide rail when the locking element against the action of the biasing spring is displaced towards the guide rail. 
     
     
         3 . The high chair according to  claim 2 , wherein the locking element comprises a rod arranged to extend along the guide rail which, at its end facing the link, is journalled in relation to the guide rail, so that the free end of the rod forms said abutment surface. 
     
     
         4 . The high chair according to  claim 2 , wherein the guide rail and the end facing away from the link has a tip, which is directed across the longitudinal direction of the guide rail and which, in relation to the link, is situated beyond the wall, in order to prevent retraction of the guide rail through the wall opening, and in that the high chair is provided with a manoeuvring cam for the tip of the guide rail, in that the manoeuvring cam is provided with a recess for the tip of the guide rail in a retracted position for the link and in that the surface of the tip facing the link and the surface of the recess cooperating with the tip surface are shaped to provide a wedge action, which at the application of a predetermined pulling force on the guide rail allows the tip to abruptly leave the recess, so that the resulting momentum becomes substantially higher than the forces acting against the swinging motion of the pair of legs towards the extended end position. 
     
     
         5 . The high chair according to  claim 4 , wherein the tip is spring biased and movable in a direction for engagement in and leaving the recess, respectively, wherein said direction extends substantially across the longitudinal direction of the guide rail. 
     
     
         6 . The high chair according to  claim 5 , wherein the guide rail is resiliently flexible in order to offer the spring biased mobility for the tip of the guide rail. 
     
     
         7 . The high chair according to  claim 1 , wherein the chair unit is rigid and further comprises a foot rest which, in relation to the seat, is rigidly attached to the chair, in that the rear pair of legs is mounted in a lower part of the link, in that the upper part of the link is journalled in a transition area between the seat and the back rest and in that all legs of the chair are mutually equally long. 
     
     
         8 . The high chair according to  claim 7 , wherein the length of the legs substantially corresponds to the largest dimension of the chair unit.
