Electric walker with collapsible guide handle

The present invention mainly discloses an electric walker with a collapsible guide handle, and particularly an electric walker capable of switching between a use position and a stowed position.

The walker can assist people with reduced mobility to walk, which provides support for the silver-haired and light-duty physical disabilities, and has positive help for rehabilitation sports training.

The commonly used walking aids are divided into two types according to whether there are wheels or not. The walking device without wheels is as follows, refer to the patent of China Patent Certificate No. M374864 "Assisting the top knee fittings of the walking aid standing by standing" The method includes a mounting assembly assembled to a frame of a walker; a support coupled to the assembly; and a knee pad secured to the support. The top knee fitting is assembled on the existing walking aid, and the walking aid can provide a knee support point, so that the user can complete the process of changing from the sitting posture to the standing posture with less lower limb strength, thereby improving the user's sitting to Station autonomy.

When the walking aid is used for walking, the user's hands are respectively supported on the support bars on both sides of the walker, and the user supports the support bar and moves the two feet forward, and the user extracts the walking device to move forward, and then repeats The action of the two feet forward further achieves the purpose of assisting walking. This type of manual walker has no wheels and requires the user to move the walker to achieve the purpose of assisting advancement.

In addition, the wheeled walker allows the user to push the walker forward at the same time. The user can control the advancement of the walker by simply pushing the walker, and the walker assists the user to advance.

For such a wheeled walker, because the wheel must be accommodated and has a large volume, when the wheeled walker is not used, its larger volume will occupy the use space, especially going out. When traveling, the huge walker takes up a limited amount of space inside the car, making the interior space even smaller.

Therefore, in order to improve the space occupied by the walker, the present invention provides an electric walker with a collapsible guide handle to improve the absence of the prior art.

The present invention "the electric walker with a collapsible guide handle" is intended to solve the technical problems existing in the prior art.

The main technical improvement of the invention is that the electric walker can be completely folded, so that the appearance and volume of the electric walker are similar to that of the chassis, and has the advantages of being convenient for traveling or carrying when going out.

A technically improved method of the present invention is that when the electric walker is completely folded, the guide handle is limited to the body via the positioning member, and the user does not need to worry that the guide handle automatically disengages from the limit of the body.

Another improved technical means of the present invention is that when the electric walker is lying down, the wheel and the guide wheel can contact the ground and travel to the ground, and the pipe of the first portion of the guide handle can provide the grip during extraction. Efficacy, when the electric walker is standing, only the wheel is in contact with the ground and travels to the ground, and the grip portion of the second portion of the guide handle can provide the gripping effect at the time of extraction.

According to another technical improvement of the present invention, the guiding handle can be extended in length, and the user can adjust the length of the guiding handle according to the height and the position of the hand, and can be applied to users of different heights.

Other objects, advantages and novel features of the invention will be apparent from the description and appended claims.
