Arc type baby crib with inclined corner seats

Abstract

An arc type baby crib has four inclined corner seats, top tubes, four bases, bottom tubes and upright tubes each being pivotally connected to the inclined corner seat and the base. The top tube is arced and is concave outward. The inclined corner seat is inclined by an angle so that a portion of the inclined corner seat pivotally connected to the upright tube is not perpendicular to a floor. The upright tube is further arced. An inner wall of the inclined corner seat is formed with a land track corresponding to a sliding slot of the upright tube. Thus, the arced top tubes and the arced upright tubes in the baby crib may be firmly and symmetrically combined when the upright tubes under the inclined corner seats are not perpendicular to the arced top tubes.

1 . An arc type baby crib, the baby crib having four inclined corner seats and four horizontal top tubes, four lower bases and a plurality of horizontal bottom tubes, wherein an upright tube is pivotally connected to the inclined corner seat and the base, the inclined corner seat is pivotally connected to the top tube, the top tube is arced, the top tube has a joint at a middle thereof and the upright tube is arced, wherein the inclined corner seat is characterized in that:
 the inclined corner seat is inclined by an angle toward a center of the baby crib so that a portion of the inclined corner seat pivotally connected to the upright tube is not perpendicular to a floor, the top tube has a straight end portion inserted into and pivotally connected to the inclined corner seat, an inner wall of the inclined corner seat is formed with a land track corresponding to a sliding slot of the upright tube, a more arced upright tube is formed so that the arc type baby crib can be fabricated according to an inclined angle of the inclined corner seat, and the inclined corner seat makes the top tube and the upright tube be firmly and strongly combined together through the land track and the sliding slot when the upright tube under the inclined corner seat is not perpendicular to the top tube.   
     
     
         2 . The arc type baby crib according to  claim 1 , wherein resisting ends extending outward are formed on two sides of the land track of the inclined corner seat, and pushing ends corresponding to the resisting ends are formed in the sliding slot of the upright tube so that the pushing ends are restricted within the resisting ends, respectively. 
     
     
         3 . The arc type baby crib according to  claim 1 , wherein an inner surface of the inclined corner seat is combined with the upright tube by at least one combination post penetrating through the inclined corner seat. 
     
     
         4 . The arc type baby crib according to  claim 1 , wherein the inclined corner seat has two pivoting housings pivotally connected to the top tubes, and the pivoting housings are perpendicular to each other. 
     
     
         5 . The arc type baby crib according to  claim 1 , wherein the top tubes are disposed on one horizontal plane when the top tubes are developed.
