Description

Walker

The invention relates to a walking aid.

By the way, because the walking aid has four-legged poles with larger spacing, it can have greater lateral support, so it can effectively assist the elderly or rehabilitation patients to walk. The walking aid disclosed in the patent number TWM481724 belongs to this kind. In order to make it easier for users to go up and down the stairs, someone invented a walker with a foot pole that can be retracted, so that the four-corner pole can resist steps of different heights by telescoping the foot pole. This is the walker disclosed in TWM540645. kind.

However, the method of retracting the foot bar is more difficult to operate. It requires the body to bend down to hold the foot bar for expansion and contraction. Therefore, for users with inconvenient lower body movements, it is very inconvenient in operation and easy to operate. Inadvertently fall, there are shortcomings that need to be improved urgently.

Therefore, it is necessary to provide a novel and progressive walking aid to solve the above-mentioned problems.

The main purpose of the present invention is to provide a walking aid that can quickly adjust the relative height of the two first foot poles and the two second foot poles for the user to go up and down stairs or walk on non-level ground.

To achieve the above objective, the present invention provides a walking aid, which includes a frame, a connecting component and two first adjusting components. The frame body includes two parallel first leg bars and two parallel second leg bars, each of the first leg bars includes a first pivotal portion. The connecting assembly includes two first crossbars and two second crossbars, each of the first crossbars includes a second pivotal portion pivotally connected to the first pivotal portion, and each of the first crossbars is pivotally connected to another A second leg, and each of the second cross bars are pivotally connected between a first leg and a second leg. Each of the first adjustment components includes a first abutment component and a second abutment component, each of the first abutment components is disposed on a first leg and can move at a first position and a second position, Each of the second card abutment components is arranged on a first crossbar. Wherein, when the two first engaging components are located at the first position, the two first engaging components are respectively engaging the two second engaging components, and the two first pivotal parts cannot be opposite to the two second engaging components. The pivoting portion rotates; when the two first engaging components are located at the second position, the two first engaging components are not engaging with the two second engaging components, and the two first pivoting components can be opposed to each other The two second pivot joints rotate.
