Long-legged chair structure

Abstract

A long-legged chair includes a chair leg frame, a seating part, a back part, a dining tray, and two armrests; the seating part is fitted on the chair leg frame in a separable manner, and it can be easily fitted to and separated from the chair leg frame; the back part is pivoted to the seating part in an adjustable manner; the armrests are fitted on top of the chair leg frame; the dining tray is fitted on and supported by the armrests in a forwards and rearwards displaceable manner such that it can be adjusted in position.

1 . An improvement on a long-legged chair structure, comprising
 a chair leg frame, and   a seating part fitted to an upper end of said chair leg frame in a separable manner,   said chair leg frame having a plurality of supporting and fixing elements on each of two inward lateral sides thereof; each of said supporting and fixing elements including a standing detainment portion, and a lying support portion joined to a lower end of the standing detainment portion; said chair leg frame having an elastic securing piece between every two said supporting and fixing elements; each of said elastic securing pieces having a hooked tail portion;   said seating part having a plurality of longitudinal detainment gaps on each of two outward lateral sides thereof; said standing detainment portions of said supporting and fixing elements of said chair leg frame being each received in a corresponding said longitudinal detainment gap of said seating part, with said lying support portions of said supporting and fixing elements propping said seating part;   said seating part having a first detainment hole between every two said longitudinal detainment gaps; said hooked tail portions of said elastic securing pieces being each received in a corresponding said detainment hole and hooked over said seating part so as to fix said seating part and said chair leg frame together.   
   
   
       2 . The improvement on a long-legged chair structure as recited in  claim 1 , wherein each of said elastic securing pieces has an aperture on each of two lateral sides and a lower side thereof. 
   
   
       3 . The improvement on a long-legged chair structure as recited in  claim 1 , wherein the seating part has a holding portion at a front end thereof, and a stopping element is partly received in and secured to the holding portion; said stopping element being in a position corresponding to a location between two thighs of a little child to prevent the little child from falling off said seating part when the little child has been seated thereon. 
   
   
       4 . The improvement on a long-legged chair structure as recited in  claim 1  further having a back part;
 each of said seating part and said back part having a plurality of second detainment holes thereon for connection with a cloth member.   
   
   
       5 . The improvement on a long-legged chair structure as recited in  claim 1  further having a back part pivoted to a rear end of said seating part; said seating part having two hollow connecting portions thereon;
 said back part having a plurality of elongate guide gaps thereon; said back part having a plurality of co-moving members each passed through a respective one of said elongate guide gaps;   said back part having a pulling element fitted thereon in a movable manner; said pulling element being joined to said co-moving members so as to cause said co-moving members to be displaced together with it;   said back part including a plurality of hooking and securing bars pivoted on two lateral sides; said hooking and securing bars being each joined to a first end of a respective said co-moving member; said hooking and securing bars facing corresponding said seating part hollow connecting portions;   said back part having a plurality of elastic elements biasing said hooking and securing bars so as to make said hooking and securing bars hooked over corresponding said hollow connecting portions to secure said back part to said seating part;   said back part being allowed to pivot relative to said seating part for adjustment of position after said pulling element is operated to move said co-moving members with said hooking and securing bars so as to separate said hooking and securing bars from said hollow connecting portions of said seating part.   
   
   
       6 . The improvement on a long-legged chair structure as recited in  claim 5 , wherein said hollow connecting portions of said seating part each include a plurality of position-limiting sections for allowing said hooking and securing bars of said back part to be hooked over. 
   
   
       7 . The improvement on a long-legged chair structure as recited in  claim 1  further having two armrests fitted on said chair leg frame, and a dining tray fitted on said armrests in an adjustable manner; said armrests each having a plurality of cavities thereon;
 said dining tray including:
 two guide rail units each fitted on a corresponding said armrest; 
 an adjustment switch displaceably fitted thereon; 
 a co-moving element connected to said adjustment switch; 
 two propping plates secured thereon; 
 two detainment blocks each joined to a respective one of two ends of said co-moving element; and 
 two elastic return elements each propped by a corresponding said propping plate; said elastic return elements each biasing a corresponding said detainment block in order for allowing said detainment blocks to pass into said cavities of said armrests so as to secure said dining tray to said armrests; 
   said dining tray being allowed to be slid over said armrests for adjustment of position after said adjustment switch is operated to move said co-moving element so as to separate said detainment blocks from said cavities of said armrests.   
   
   
       8 . The improvement on a long-legged chair structure as recited in  claim 7  further having a secondary dining tray fitted on said dining tray in a separable manner; said secondary dining tray having locating protrusions thereon; said locating protrusions having corresponding locating holes formed on an upper side of said dining tray.
