Claims

[Claims for Utility Model Registration] 1. Similarity in front view between a front wheel support leg A formed into an almost U-shaped frame that maintains a constant interval W1 and a constant interval W2 that is wider than the front wheel support leg A when viewed from the front. A rear wheel support leg B formed into a U-shaped framework, and a fixed interval W wider than the rear wheel support leg B.
The front wheel support leg A, the rear wheel support leg B, and the pusher frame C are all made of hollow metal pipes to support both of them. A pair of left and right reinforcing pins 15 are provided at the upper ends of legs A and B.
22 are respectively implanted and fixed, while a pair of left and right reinforcing pins 25 are implanted and integrated into the lower end of the pusher frame C, and the exposed heads 16 of the reinforcing pins 15, 22, 25 are integrated.
, 23, and 26 are aligned side by side,
One pivot shaft 2 to the exposed head 16, 23, 26
By skewering and penetrating the front wheel support legs 8 horizontally, the front wheel support leg A, the rear wheel support leg B, and the pusher frame C are rotatably assembled, and the reinforcing pin 15 of the front wheel support leg A in the above-mentioned side-by-side state is attached. Between the adjacent reinforcing pins 22 of the rear wheel support leg B, a set of two parallel fitting protrusions 32 are horizontally extended from the exposed head 23 of one of them, and the remaining exposed head of the other 16 and each fitting protrusion 32
By opening the receiving groove 33 correspondingly and fitting the protrusion 32 and the groove 33, the front wheel support leg A and the rear wheel support leg B can be rotated in a rotation angle range θ of 45 to 60 degrees.
The reinforced pin 22 of the rear wheel support leg B and the reinforced pin 25 of the pusher frame C, which are also in a side-by-side state, are designed so that they can be opened and closed relative to each other. different from 1
The fitting protrusion 34 is extended horizontally, and the receiving groove 35 of the fitting protrusion 34 is opened correspondingly in the remaining exposed head 26, and the protrusion 3 is opened.
4 and the concave groove 35, the pusher frame C can be raised and lowered in a rotation angle range γ of 225 to 240 degrees with respect to the rear wheel support leg B, and both support legs A and B can be opened and closed. Operation status and pusher frame C
2. A folding type elderly person's carriage, characterized in that the up-and-down operation state of the folding wheel can be locked by tightening a fixing nut 30 screwed onto the end of the pivot shaft 28. 2. A reinforcing bar 36 is placed horizontally at the mid-height position of the front wheel support leg A so as to be slidable in the vertical direction, and a locking pawl 38 is integrally projected downward from the center of the reinforcing bar 36, and the front wheel is also supported. A bottom receiving seat 40 of a shopping bag 42 is pivotably mounted near the lower end of the leg A, and the bag receiving seat 40, which is laid down so as to overlap the front wheel supporting leg A, supports the front wheel. The locking claw 38 of the reinforcing bar 36 slides downward along the leg A,
2. The foldable elderly person's car according to claim 1, characterized in that it is configured to be lockable.
