Description

Lower limb aids

The invention relates to an auxiliary device, in particular to a lower limb accessory.

Most of the existing lower limb assistive devices passively support the user, and then the lower limbs of the user are driven to achieve the effect of assisting walking or rehabilitation. With the advancement of science and technology, in recent years, for users with lower limb weakness or lower extremity paralysis, the relevant industry has developed the "Proactive Action Aid" of the Republic of China Patent Announcement No. I342767, as shown in Figure 1. The active mobility aid 1 It is a technique in which the driving device 11 actively drives the user's lower limbs to swing, thereby assisting the user with lower limb weakness or lower limb paralysis.

Although it is assisted by lower limbs, it is difficult for long-distance or long-term use for passive or active lower limbs to walk or rehabilitate users who are inconvenient in lower limbs or incapable or even paralyzed. Walking. In order to improve the above-mentioned shortcomings, the related art has developed a patent application such as U.S. Patent No. 20110201978, which is improved in that it combines a lower limb assistive device with an electric wheelchair so that the user can perform long-distance movement.

However, combined with lower limb support and electric wheelchairs, not only has a significant increase The volume of the lower limb aids causes inconvenience in use and storage troubles, while greatly increasing the cost.

Accordingly, it is an object of the present invention to provide a lower limb assistive device that is small in overall size, that facilitates storage, and that assists the user in long-distance movement or rehabilitation.

The lower limb assisting device of the present invention comprises a supporting unit and a carrying unit connected to the supporting unit. The support unit includes a lumbar support mechanism that can cooperate with a user's waist, and two leg support mechanisms respectively corresponding to the user's legs and spaced apart from the lumbar support mechanism.

The carrying unit includes a carrying mechanism between the leg supporting mechanisms, and a positioning mechanism disposed at a distance from the leg supporting mechanism to the lumbar supporting mechanism.

The positioning mechanism is movable between a walking position and a seating position. When in the assisting position, the positioning mechanism is spaced from the ground. When in the seating position, the positioning mechanism and the leg supporting mechanism and the ground Contact, and the user's buttocks can be placed on the carrier.

The utility model has the beneficial effects that the positioning mechanism can be used to move between the assisting position and the seating position, which not only assists the user to walk or rehabilitate, but also allows the user to take a rest and proceed. Long-distance movement, and the overall small size is conducive to storage.
