Description

Walker structure

The creative department belongs to the technical field of an auxiliary device, and specifically refers to a walker structure that can be adjusted in height and easy to be folded, thereby saving space for storage and transportation, and adjusting the support height according to actual needs, thereby Improve its practicality.

According to the people with poor mobility, such as the elderly, patients, and the disabled, if they stay in bed for a long time or sedentary, they often cause hemorrhoids and sores. Furthermore, if the person with poor mobility is not rehabilitated for a long time, his muscular endurance and coordination will degenerate over time, and he will gradually lose the ability to move autonomously. At this time, it is necessary to assist with the aid of related auxiliary devices. The industry has developed a variety of walking aids for the elderly, inconvenient or disabled people to use as auxiliary aids, prevention and exercise aids. The current common walkers are mainly made up of skeletons on both sides. The roller is arranged at the bottom of both ends of the two skeletons, so that the user can hold the crossbars on both sides of the skeleton with both hands to support the body and move the walker. However, the common problem is that the user corresponding to different heights cannot adjust the height, so that the user with different support heights cannot be satisfied, and when the support height does not meet the user's demand, the support force is improper, which not only affects The comfort of use, and in the case of insufficient coordination of people with reduced mobility, dangers may also occur, resulting in the use Inconvenience and safety concerns; in addition, the user uses the way of holding the skeleton to obtain support, the action area is small, and can not be supported by the arm, which affects the convenience of use, and when stored or transported, It is also not easy to be fast, or even impossible to fold, resulting in space occupation during storage or transportation.

In other words, how to have a walker that is easy to adjust height and can be quickly folded is a demand for users with limited mobility, and how to solve the above problems is the subject of this creation.

In view of this, the creator has in-depth discussion on the problems faced by the aforementioned existing walkers, and has been actively seeking solutions through years of experience in R&D and manufacturing of related industries, and has finally succeeded through continuous efforts in research and trials. The development of a walker structure can effectively overcome the troubles and inconveniences caused by the difficulty of adjusting the height and folding of the existing walker.

Therefore, the main purpose of the present invention is to provide a walker structure, which can facilitate the user to adjust the support height, meet the use requirements of different support heights, and improve the comfort and safety of use.

Moreover, another main object of the present invention is to provide a walker structure which can be easily folded and contracted to save space for storage and transportation, and further enhances its practicability.

Accordingly, the present invention mainly achieves the foregoing objectives and effects through the following technical means: the at least one set of tripods and one set of risers are provided: wherein the set of tripods is a bracket which is parallel on both sides and One at The cross-link set between the two sides of the bracket has at least one link mechanism, and each of the link mechanisms is composed of two links which are interlaced in the middle section, and two of the link mechanisms An adjusting mechanism is respectively arranged on the opposite upper ends of the connecting rod for adjusting the height of the strut group, and a lower limiting mechanism is respectively arranged on the opposite lower ends of the two connecting rods for selectively folding the brackets on both sides of the tripod set The gusset set includes two pad bodies and a pivoting mechanism disposed between the two pad bodies, wherein the bottom surfaces of the two pad bodies are respectively pivotally provided with a splicing rod that can be synchronously slidably inserted into the brackets on both sides of the pedestal set And the two plungers have a plurality of positioning holes corresponding to the adjusting mechanism of the cross-link group, and the pivoting mechanism comprises a first rotating body and a second rotating body, wherein the first and second rotating bodies respectively have a relative a mounting portion fixed by the pad body, and the first and second rotating bodies have a shaft portion that can be oppositely disposed, and the first and second rotating bodies are selectively positionally limited to rotate, so that the two sides of the pad body can be positioned or unfolded or folded Received.

Therefore, through the above-mentioned technical means, the creation of the walker structure can greatly enhance the safety of use and enhance its practicability, thereby greatly increasing the added value of the product and improving the economic efficiency and competitiveness of the product.
