MULTI-SECTION COLLAPSIBLE LEG STRUCTURE OF HIGH

CHAIR FOR INFANT BABY

BACKGROUND OF THE INVENTION

1. Field of the invention

The present invention relates to a multi-section collapsible leg structure of high chair for infant baby, particularly to a multi-section design of the legs of high chair in which not only the chair after assembling can be used as a general high chair for infant baby, but also the chair can be used as a low stool after the leg units of each leg are detached with each other. The volume or the space occupied either in its packing or in delivery can be apparently reduced so that the cost of delivery can be lowered. In this manner, convenience in practical application is further enhanced in its entire operation.

2. Brief Description of the Prior Art

Generally, infant baby is not tall so that usually a special chair is provided for baby at mealtime in order to allow the baby seat at the same height as adult. In this way, not only the infant baby has participating feeling in mealtime but also adult is convenient in feeding the infant baby. Thus, the relevant industries have developed a variety of high chairs exclusively for infant baby such that infant baby can have his meal by taking a seat on the high chair. Conventionally, the high chair

S

for baby typically has a seat section which has legs with predetermined height provided downward on the bottom end face, and a seat back section integrally formed vertically on the back end of the seat section, and further a meal-tray provided at the front end of the seat section.

When infant baby seats on the high chair, his back is supported by a force from the seat back section, and an equal-height with adult is obtained by the chair-legs having predetermined height so as to facilitate dining.

However, although the above high chair of infant baby can achieve expected effectiveness of having meal at equal height with adult, it is found in practical use that the chair-legs are usually of integrally-molded design to have definite height so as to achieve the equal-height effect.

Although this type of high chair, which to some extent can provides required function for infant baby when in use, occupies remarkable space due to undetacheable design of the chair-legs. Thus, not only the volume after packing is so large as to cause inconvenience in storage or in delivery but also the cost of storehouse and delivery is increased.

Eventually, consumer will be the looser, as the increased cost is always imposed on the end user. Therefore, there still exists some space to be improved in its practical use.

In view of the above defects, the inventor of the present invention thus undergoes the research and improvement with respect to the conventional high chair based on the professional knowledge and experience accumulated in the long term involvement of relevant field, and eventually proposes a multi-section collapsible leg structure of high chair for infant baby, and higher value of practical use can certainly be expected.

SUMMARY OF THE INVENTION

The multi-section collapsible leg structure of high chair for infant baby of the present invention, having chair-legs provided downward on the bottom end face of a seat section, wherein each chair-leg is formed by the connection of several leg units, a shrinking segment being connected to the bottom end of the upper leg unit and a resilient engaging unit being housed within the shrinking segment, an insertion hole corresponding to the shrinking segment of the upper leg unit being provided on the top end of the lower leg unit such that the shrinking segment of the upper leg unit of each chair-leg can be inserted therein, an engagement hole corresponding to the resilient engaging unit being provided outward on the side edge of the insertion hole such that the resilient engaging unit can be engaged therein to ensure positioning. In this manner, not only the high chair after assembling can be used for general high chair for infant baby, but also the leg units of each chair-leg can be detached with each other such that the high chair can be used as a low stool. The volume or the space occupied either in its packing or in delivery can be apparently reduced so that the cost of delivery can be

S

lowered. In this manner, convenience in practical application is further enhanced in its entire operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The technical contents of the present invention will become more apparent from the detailed description of the preferred embodiment in conjunction with the accompanying drawings.

Firstly referring to Figure 1 and 2 that are respectively the perspective exploded view of the present invention and the partial

S

enlarged sectional view of the present invention, the high chair for infant baby of the present invention mainly has chair-legs (2) provided downward on the bottom end face of a seat section (1).

Each chair-leg (2) is formed by the connection of several (two is taken as example in this invention) sections of leg units (21), (22). A shrinking segment (212) is connected by a step edge (211) to the upper leg units (21), and a resilient engaging unit (23) is housed within the shrinking segment (212). The resilient engaging unit (23) includes a resilient element (231) elastically compressed within the shrinking segment (212) and an engaging piece (232) connected at one end of the resilient element (231). The engaging piece (232) projects out of a through hole (213) provided on the side edge of the shrinking segment (212) by the action of the spring force from the resilient element (23 1).

An insertion hole (221) corresponding to the shrinking segment (212) of the upper leg unit (21) is provided on the top end of the lower leg unit (22). An engagement hole (222) corresponding to the resilient engaging unit (23) is provided on the side edge of the insertion hole (221).

In this way, referring to Figures 3 and 4 that are respectively the sectional side view of the assembly of the present invention and the perspective outline view of the present invention in use state, the shrinking segment (212) of the upper leg unit (21) of each chair-leg (2) is inserted into the insertion hole (221) of the lower leg unit (22). The step edge (211) of the shrinking segment (212) is abutted at the upper end of the insertion hole (221) of the lower leg unit (22) to provide a limit action. In this state, the engaging piece (232) of the resilient engaging unit (23) inside the shrinking segment (212) is projected out of

S

the through hole (213) by the action of the spring force from the resilient element (231), and is engaged into the engagement hole (222) to ensure positioning. Thus, the high chair after assembling can be used for infant baby.

Further, referring to Figure 5 showing the sectional side view of the present invention in disassembled state and Figure 6 showing another perspective outline view of the present invention in using state, the engaging piece (232) projected out of the through hole (213) on the upper leg unit (21) is pressed inward from the engagement hole (222) of the lower leg unit (22) such that the engaging piece (232) is moved inward to detach from the engagement with the engagement hole (222).

In this manner, the shrinking segment (212) of the upper leg unit (21) can be separated from the insertion hole (221) of the lower leg unit (22), and the high chair after disassembling can be used as a low stool having the upper leg unit (21) combined therewith.

While the present invention has been described with preferred embodiments in conjunction with the accompanying drawings, it is noted that the preferred embodiments and the drawings are purely for the convenience of description only, not intended to be restrictive on the structural aspect or dimension of the present invention.
