Description

Easy-to-close accessory structure

The invention relates to an auxiliary device structure which is easy to be folded, and particularly relates to an auxiliary device structure which has a rapid unfolding and folding.

According to newspapers and magazines, the number of elderly people over the age of 60 in China exceeded the young population of 0 to 14 years old in 2011. This shows that the speed of the aging population in China is fast and urgent. Because the elderly are inconvenient due to degeneration of the body, it is easier for the average adult to feel tired and the waist and legs are more weak. When sitting or getting up, it is easy for the knee joint strength to fall and support it to fall, or even difficult to stand on its own. Walking and sitting often require assistance from others, so the elderly usually use wheelchairs or walkers to assist walking.

However, the current mechanism is a single function. In other words, the wheelchair is only wheelchair-enabled. The walker only has the auxiliary walking function. At present, most of the mechanism settings are for the walker to be mounted behind the wheelchair. When the patient wants to use, the patient and the relatives are invited. Helping to remove the walker is not only inconvenient for the patient, but also less dignified.

Based on the above, the inventor of the present invention designs an auxiliary device structure that is easy to be folded. When the walker function is to be used, the support frame of the walker is provided with a spring rope, which expands/folds the support frame, which is labor-saving and simple. When the effect is used and the walking function is not required, the walker is conveniently folded into a wheelchair for use as a table.

The main object of the present invention is to provide an auxiliary structure that is easy to fold, and the support frame of the walker is provided with a spring rope, which has a labor-saving effect of unfolding/folding the support frame.

A second object of the present invention is to provide an auxiliary device structure that is easy to be folded. The walking device has a plate body, and the support frame has a fastening member that corresponds to the armrest of the wheelchair, so that the walking device is coupled to the walking device. A cloth shaft is provided on the armrest.

In order to achieve the above object, the present invention comprises a cloth shaft having a fixed end and a movable end, wherein the left and right sides of the fixed end are respectively provided with a rotating shaft, and the movable end is wound with an elastic cloth; the second supporting frame has its respective shaft The rotating shaft is arranged on both sides of the cloth shaft, and the supporting frame is bent into an inverted U shape, and the supporting rod has a three-tube body supporting rod with a pivoting end, and the supporting frame is provided with a spring rope a snap-on portion having a snap-fit member for assembling the armrest of the wheelchair, and a fastening member for fixing the movable end of the cloth shaft; a spring rope, the two sides of which are fixed to the hook portion of the support frame and the spring The rope is disposed on the strut; the present invention is characterized in that: when unfolding, the support frame is deployed outward, and the spring in the strut is in a shape of a figure; when folded, the support frame is bent inward, the strut The pivoting end and the spring rope are bent into a zigzag shape, and the engaging member is fixed on the armrest of the wheelchair, and the movable end of the cloth shaft is hung on the fastening component of the support frame, and the auxiliary device having the function of folding and unfolding is effective. Structure.

Therefore, according to the technical means of the present invention, the functions obtained by the present invention are briefly described as follows: 1. The support frame is provided with a spring rope, which has the advantages of good bending and returning to the original state, and therefore, the present invention is easy to use. The practical effect of the exhibition. 2. The present invention is provided with a cloth shaft having an elastic portion. When the storage frame is engaged with the wheelchair and the movable end of the cloth shaft is fixed, it can be used as a wheelchair table, and the walker has an additional function.

In order to enable your review board to have a better understanding and recognition of the characteristics and characteristics of the case, the following preferred examples are listed below with the following description:

When unfolding, the support frame 20 is deployed outwardly, and the spring in the support rod 21 has a shape of a straight shape; when folded, the support frame 20 is bent inward, the pivot end 22 of the support rod 21 and the spring rope 30 is bent into a zigzag shape, and the engaging member 24 is fixed on the armrest of the wheelchair, and the movable end 11 of the cloth shaft 10 is hung on the fastening member 25 of the support frame 20, and the auxiliary structure having the function of folding and unfolding is obtained. By.

According to the technical means of the present invention, the mode of use of the present invention and the obtained effects are briefly described as follows:

1. Referring to the first figure, when the user wants to use the invention to assist walking, the support frame 20 is first deployed outward. Since the spring rope 30 is fixed to the hook portion 23 of the support frame 20, the spring rope 30 is elastically restored. The shape of the figure and the assistance of the support frame 20 are unfolded, so that a quick deployment effect can be obtained.

2. Please refer to the second, third, fourth and fifth figures. When the user wants to receive the invention, the support frame 20 is folded along the inner side of the rotating shaft 12. Since the strut 21 is composed of three sections of tubing, the strut 21 will In a zigzag shape, the length of the strut 21 is shortened, the engaging member 24 is fixed to the armrest of the wheelchair, and the movable end 11 of the cloth shaft 10 is hung on the engaging member 25 of the support frame 20. The cloth shaft 10 is composed of one. The elastic cloth 13 is made to provide a stable arrangement of the articles after being unfolded, so that in the present state of use, the present invention can provide a walker with a special function as a wheelchair.

3. Referring to the first figure, the bottom of the support frame 20 is provided with an adjustment rod 26, and the bottom of the support frame 20 has a hole in the vertical direction, and then a four-legged frame 27 is respectively fitted on the four bottom ends of the support frame 20. Moreover, the corresponding hole is inserted, and the adjusting rod 26 is inserted into the hole of the support frame 20 and the stand 27, thereby obtaining the effect of adjusting the height of the support frame 20.

According to the above ideas, the present invention can also be implemented in the following aspects: (1) The cloth shaft 10 can be replaced with a plastic sheet, a plastic steel plate, etc., and the shaft 12 is provided with a rotating shaft 12 on both sides, and the support frame 20 is disposed on the shaft. On both sides of the main body, the strut 21 is provided with a clamping portion fixing plate body, which can be better stabilized and easily cleaned through the plate body when stored and used in the state of use.

In summary, in the present case, the support frame 20 is provided with a spring rope 30. The support foot is unfolded/folded, which has the effect of labor saving, simple use, and does not need to use the walking function, and the walking aid is conveniently folded. The wheelchair is used as a table, and its structure has not been seen in various books or publicly used. It is in line with the requirements of the invention patent application, and it is requested to express the patent as soon as possible.

It is to be understood that the above is the technical principle immediately applied to the specific implementation of the present invention. If the function of the present invention is changed, the function produced by the present invention does not exceed the spirit of the specification and the drawings. All should be included in the scope of the present invention.
