The present invention relates to a silver walking car having a latch gear unit, and more particularly, when folding or unfolding a silver walking car, the silver walking car can effectively prevent the phenomenon that the silver walking car is unfolded or folded in reverse. It relates to a silver walking car equipped.

In the case of elderly people or patients, it is difficult to walk with only two legs.

In the past, a walking stick has been used as a walking aid, but in recent years, there are wheels that use a walking aid that can easily walk with less force on the shoulder than a walking stick while holding and pushing the handle, or a similar stroller walking aid. It is used as a substitute for.

Various types of walking aids or strollers of this type have been filed in Korea Patent Office Application No. 10-2009-0091741 (Prior Art 1), Application No. 10-2010-0040639 (Prior Art 2), and Application No. 10-2008- It is widely known from 0136206 (Prior Art 3) and Application No. 10-2008-0070782 (Prior Art 4).

However, in the case of the aforementioned prior arts 1 to 3, as a simple stroller-type walker, due to structural limitations, the light front wheel is lifted upward during use and there is a high risk of being overturned, so it is not safe for patients or the elderly to use.

In addition, the prior art 4 is an electric stroller and requires additional power, which can increase the cost burden.

Accordingly, the present applicant has proposed a silver walking vehicle as shown in FIGS. 1A and 1B.

First, due to the structural limitation of the folding link 6, when folding or unfolding a silver walking car as shown in FIG. 1B, there is a fear that it may unfold, particularly when folding a silver walking car. If the folded silver pedestrian car is unfolded arbitrarily, it may be necessary to improve this part because it must be folded again.

Second, the current silver walking car has a structure in which the handle 7 is present in a pair on both sides with the bag 1 interposed therebetween, as shown in FIG. 1A, and the structure of the handle 7 is also for the elderly or patients of the elderly. Improvements in this area may be required as it may be inconvenient for the user.

As a result, the present applicant has improved the detailed structure to make the silver walking vehicle, which is currently used for the elderly and patients of the elderly, more convenient for the elderly or patients of the elderly.
