Embodiment Construction

[0053] Next, embodiments of the walker and restraining device of the present invention will be described with reference to the drawings. figure 1 It is a perspective view showing the first embodiment of the walker of the present invention.

[0054] The walker 1 according to the first embodiment of the present invention is basically unchanged from the existing walker except for the slide lock mechanism 10 . The walker 1 has a lower frame 110 , an upper frame 120 , a first frame 130 and a second frame 140 that can be separated and closely connected to the lower frame 110 and the upper frame 120 in parallel.

[0055] The lower frame member 110 is in the shape of a substantially oblong rectangular ring in the front-rear direction, and is made of synthetic resin such as polypropylene. The lower frame 110 has a slowly inclined outer peripheral wall 111 gradually approaching the ground toward the outer periphery, and a rapidly inclined inner peripheral wall 112 gradually approachin...

Abstract

The invention provides a walker which have excellent property in durability and reliability with slide lock mechanism, and have superior safety and impact mitigating performance in folding, and provides a stopper member used therefor. The slide lock mechanism includes a rack member fixed back and forth on the lower surface of an upper frame member, a slide member which pivotally supports a second frame so as to be freely rotatable and is attached to the rack member so as to be slidable back and forth and a pawl member which is arranged in the second frame so as to be freely rotatable back and forth and has a metallic shaft, at the end, for fixing the slide of the second frame by engagement with teeth of the rack member. The intervening soft resin stopper member is projected from the upper frame member slantly downward to the outer part side.

Description

field of invention [0001] The present invention relates to a walker and a restraining device for infants, in particular to a walker for infants and a restraining device adopted in the walker for infants whose height can be adjusted to improve the safety when folded. Background technique [0002] In the growth process of children, walkers have been used in the past for practicing walking and the like. In this walker, it is hoped that the height can be adjusted in accordance with the growth process of the child. [0003] The general structure of a walker is as Figure 9 shown in Figure 9 In , in order to understand the structure of the frame easily, the upper frame parts are indicated by dotted lines. This walker 600 has the ring-shaped lower frame 110 supported on a plurality of casters 115 that can turn freely, and is provided with the upper frame 120 that puts into the opening 122 and the seat portion 123 of the child, and the lower frame 110 can be placed The reverse U-...
