Description

wheelchair

The present invention relates to a wheelchair, and more particularly to a wheelchair having a table top.

Wheelchairs are used to assist in the movement of pedestrians. In recent years, wheelchairs have become a very common mobility aid due to the increase in barrier-free space. Wheelchairs can be roughly divided into manual wheelchairs and electric wheelchairs according to their power sources. The former is lighter and cheaper, but the mobile method relies on manpower. The latter is heavier and more expensive but is driven by electricity and can be moved without relying on manpower.

However, the general wheelchair lacks the desktop for the user to place the item, whether manual or electric. Therefore, the desktop needs to be used every time. For example, when dining, the user needs to leave the wheelchair to go to another place, and then take the wheelchair again after use. Undoubtedly a great burden for users with limited mobility. The current common solution is to carry another table, take out the table and place it on the armrest of the wheelchair when needed, but the whole piece of the table is not easy to carry, and it needs to be fixed separately to prevent slipping. inconvenient.

Accordingly, it is an object of the present invention to provide a wheelchair having a table top.

Thus, the wheelchair of the present invention includes a seat and a seat a first armrest on one side, a second armrest on the other side of the seat, and a table panel removably disposed on the first armrest. The seat includes a seat portion and a reclining portion extending upward from a rear end of the seat portion. The first armrest is disposed on one side of the seat portion. The second armrest is disposed on the other side of the seat portion.

The table board includes a swing arm portion pivotally provided at a front end of the first armrest, and a plate body portion pivotally mounted on the swing arm portion. The arm portion is rotatable relative to the first armrest between a collapsed position and a deployed position. In the folded position, the arm portion is juxtaposed with the first armrest, and in the deployed position, the arm portion is located in front of the first armrest. The plate body portion may be unfolded toward the second handrail with the arm portion as a shaft to place the article.

The effect of the invention is that when the table top is needed, the table can be unfolded from the first handrail for the user to use, and after use, the table can be taken back in place, so that no additional table board is needed. The convenience is improved, and the table is pivoted on the first armrest, so it is very stable and does not slip.

The cover portion 122 is slidable in the direction of the arrow A with respect to the accommodating portion 121 as shown in FIG. 3(b), and can be matched with the accommodating portion 121 as shown in FIG. 3(a). The table 14 is closed and received. As shown in FIG. 1, the second armrest 13 is disposed on the other side of the seat portion 111. In the preferred embodiment, the first armrest 12 is disposed on the right side of the user. The first armrest 12 may be disposed on the left side of the user, or the cover portion 122 may be Sideways open, not limited to this.

Referring to FIG. 2, the table 14 includes a swivel arm portion 141 pivotally disposed at a front end of the receiving portion 121 of the first armrest 12, a plate portion 142 pivoted on the arm portion 141, and a pivot The plate body portion 142 is opposite to the extending portion 143 on one end of the arm portion 141. The arm portion 141 is rotatable relative to the first armrest 12 between a collapsed position and a deployed position. Referring to FIG. 3( a ), in the folding position, the plate body portion 142 and the extending portion 143 are stacked and arranged in the receiving portion 121 and are hidden by the cover portion 122 . When the table top 14 is to be used, the cover portion 122 is opened in the direction of the arrow A as shown in FIG. 3(b), and the arm portion 141 is further bent as shown in FIG. 4(a). Rotating in the direction of the arrow B, the arm portion 141 can be inverted from a folded position as shown in Fig. 3 (a) to a deployed position as shown in Fig. 4 (b). Next, as shown in FIG. 5(a), the extending portion 143 is unfolded in the direction of the arrow C with respect to the plate portion 142, and the plate portion 142 is formed with the spiral arm as shown in FIG. 5(b). The portion 141 is pivoted in the direction of the arrow D. Referring to FIG. 5(c) and FIG. 6, the body portion 142 and the extending portion 143 are horizontally arranged side by side for the user to place the object, and the extending portion 143 is abutted against the second armrest 13 for lifting. Support stability.

It should be further noted that the table 14 is made of a material that is light in weight and strong in load, such as aluminum alloy or plastic steel. Referring to FIG. 7 and FIG. 8 , the plate body portion 142 and the extending portion 143 may also be in the form of a guide angle as shown in FIG. 7 . In this type, when the arm portion 141 is in the When moving between the folding position and the unfolding position, the plate body portion 142 is less likely to interfere with the accommodating portion 121, and the user can be prevented from being injured by the corners of the plate portion 142 and the extending portion 143, thereby improving safety. Sex.
