  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • Referring to FIGS. 1 and 7, an embodiment of a high chair (3) for a child according to the present invention includes a foldable frame work (2), a seat portion (31), a backrest (32), an adjusting mechanism (5) movable along the backrest (32), and a connecting element (4) which is pivotally interconnected to the adjusting mechanism (5) and the foldable frame work (2). The adjusting mechanism (5) can be manipulated to move along the backrest (32), thereby pivotally carrying the connecting element (4) to different inclination angles, so as to support the backrest at a variety of corresponding inclination angles. A user can therefore adjust the inclination of the backrest with one hand only.
  • Referring to FIGS. 7 and 8, the position of the foldable framework (2) includes a deployed position and a collapsed position. The foldable framework (2) has a front leg (21), a rear leg (22) and a pivot element (23). The pivot element (23) pivotally connects with the front leg (21), the rear leg (22) and the connecting element (4), so that the front leg (21) and rear leg (22) can either be deployed to support the seat portion (31), or collapsed into a compact size for storage in a limited space.
  • The seat portion (31) pivotally connects the front leg (21) and the rear leg (22) at the both sides, and pivotally connects the backrest (32) at a rear end therefore. This allows the backrest (32) to pivot about the rear end of the seat portion (31), as seen in the dashed lines illustrated in FIG. 7.
  • In order to guide movement of the adjusting mechanism (5) along the backrest (32), the back of the backrest (32) may preferably be formed with two adjusting channels (321) which extend parallel to each other as shown in FIG. 2. Furthermore, a slot (322) is formed parallel to the two adjusting channels (321) as shown in FIG. 3.
  • The connecting element (4) has two arms (41) and a pivotal portion (42). The arms (41) extend parallel to each other. Referring to FIGS. 1 to 3, each of the arms (41) pivots with the pivot element (23) at one end, and connects to the pivotal portion (42) at the other end. The arms therefore form a U-shaped connecting element (4) which pivotally interconnects the foldable framework (2) and the backrest (32), and provides the backrest (32) with support for different inclination angles, as the dashed line shows schematically in FIG. 7.
  • Referring to FIGS. 2 to 6, the adjusting mechanism (5) may further comprise a pivotal base (51), a limiting piece (53) and a manipulating member (52). The pivotal base (51) pivotally holds the pivotal portion (42) of the connecting element (4), and can carry the pivotal portion (42) while moving along the adjusting channels (321), in order to provide adjustable inclination support for the backrest (32).
  • Referring to FIG. 3, the pivotal base (51) is formed with a pair of catching blocks (511) and a pair of receiving troughs (512), wherein the pair of catching blocks (511) can selectively engage with the bottom of the adjusting channels (321), as is shown in FIG. 5. The manipulating member (52) is pivotally connected to the pivotal base (51) and formed with a prop-up portion (521). The limiting piece (53) is formed with a pair of salient posts (54) which is configured to penetrate through the guided slot (322) and may be moved back and forth within the receiving trough (512) of the pivotal base (51) as shown in FIG. 4. Preferably, a resilient element (55) is telescopically accommodated within the receiving trough (512) for biasing against the pair of salient posts (54), thereby providing a force to keep the pair of catching block (511) engaged with the bottom of the adjusting channels (321). This fixes the inclination position of the connecting element (4) and the backrest (32). In this embodiment, the resilient element can be a compression spring.
  • Once the manipulating member (52) is pressed in the direction indicated by the arrow indicated in the FIG. 6, the prop-up portions (521) are turned to press against the surface of the backrest (32), thereby lifting the catching blocks (511) to disengage from the adjusting channels (321). This carries and moveably repositions the connecting element (4) along the adjusting channels (321) into a new inclination position.
  • Preferably, the catching block (511) and the bottom of the adjusting channel (321) are formed and engaged with a pawl or detent-like portions, through which a user can push the backrest (32) upwardly to change the inclination angle without pressing the manipulating member (52). In this way, the present application creates a more convenient method of operating a high chair, and facilitates operation and adjustment of the backrest with only one hand.
  • The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
