Brief Patent Description - Full Patent Description - Patent Application Claims
BACKGROUND OF THE INVENTION [0001] 1.Field of the Invention [0002] This invention relates to a high chair for children with backrest having adjustable inclination and, more particularly, to a high chair which makes use of a pivotal base movable along an adjusting channel of the backrest for pivotally carrying a connecting element, thereby providing the backrest with different support angles, so as to adjust the inclination angle of the backrest. [0003] 2.Description of the Prior Art [0004] A high chair provides a child with a seat for taking a meal. Examples of high chairs can be found in U.S. Pat. No. 5,435,620, U.S. Pat. No. 4,958,885, U.S. Pat. No. 5,509,719, U.S. Pat. No. 5,348,374, U.S. Pat. No. 5,507,550, U.S. Pat. No. 5,806,922, U.S. Pat. No. 5,829,826, U.S. Pat. No. 5,927,805, U.S. Pat. No. 5,951,102, and U.S. Pat. No. 6,010,184. Basically, a high chair may comprise a seat portion, a meal tray on top of the seat portion, and a set of chair legs which stand on the floor. [0005] To accommodate children of different ages who may still be growing or those who may be short, the backrest must be adjusted according to each child's size, to find an inclination angle comfortable for each specific child. U.S. Pat. No. 6,666,505 provides an example of angle adjustment for a backrest, wherein the backrest adjusting device is furnished at both sides of the seat portion so as to adjust the inclination angle of the backrest. However, the structure of said chair is complicated and tedious. Further, for effecting the adjustment, it is necessary to manipulate both sides of the chair at same time. SUMMARY OF THE INVENTION [0006] In order to resolve the above-mentioned troubles with operation, the present invention provides a high chair for children with a simple control mechanism for adjusting the inclination of the backrest. The high chair for children according to the present invention may including a foldable frame work, a seat portion, a backrest, an adjusting mechanism movable along the backrest, and a connecting element pivotally interconnected between the adjusting mechanism and the foldable frame work. The adjusting mechanism can be manipulated to move along the backrest and carries the connecting element pivotally to change to different inclination angles, so as to support the backrest at different inclination angles. [0007] Preferably, the backrest further has an adjusting channel elongated in a vertical direction for guiding the adjusting mechanism. [0008] The adjusting mechanism preferably includes a pivotal base and a manipulating member wherein the pivotal base has a catching block for positioning along the adjusting channel. The manipulating member is pivotally connected to the pivotal base. When adjusting the backrest, a user can move the manipulating member with one hand and carry the connecting element to different inclination angles that can support the backrest with desired inclination angles. [0009] During adjusting the backrest, a user can feel the weight of the baby with the hand. The user is therefore capable of avoiding the hazard of a suddenly drop of the backrest. [0010] Further scope of the applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description. BRIEF DESCRIPTION OF THE DRAWINGS [0011] The present invention will become more fully understood from the detailed description given hereinbelow and the accompanying drawings which are given by way of illustration only, and thus are not limitative of the present invention, and wherein: [0012] FIG. 1 is a side view of a high chair with a backrest having adjustable inclination of the present invention; [0013] FIG. 2 is an exploded view of the members of an adjustable device of the present invention; [0014] FIG. 3 is an exploded view from another view angle different from that of the FIG. 2 of the members of an adjustable device of the present invention; [0015] FIG. 4 is a cross-sectional view of the assembly of a limit sheet and a pivotal base of the present invention; [0016] FIG. 5 is a cross-sectional view showing that the adjusting channel meshes with catching block of the present invention; [0017] FIG. 6 is a cross-sectional view showing the action that the prop-up portion of the manipulating member pushes the backrest to move of the present invention; [0018] FIG. 7 is a side view showing that the backrest rotates at different angles of the present invention; [0019] FIG. 8 is a side view showing that the framework of the child high chair is folded up of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT [0020] 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. Continue reading about High chair with a backrest having adjustable inclination...
