M284371 捌、新型說明： 一、 【新型所屬之領域】 本案輪椅主輪之手推部輪圈改良結構，係與一般輪椅 主輪之手推部輪圈有關，更詳而言之，即針對如何令手推 部輪圈在作手推前進時，能提供一符合人體工學之舒適握 持所作之結構創作. 二、 【先前技術】 按以一般行動不便者，必須藉助輪椅使自己移動，因 此輪椅主輪部份便有許多輔助之裝置，常見的有業者會在 輪椅主輪加裝手推部輪圈之結構，以便令使用者手臂能配 〇手推部提供一施以手推前進之力量。 而以習式輪椅主輪之手推部輪圈結構觀之，其乃大都 採以呈管體之鋁合金或不鏽鋼等材料製成，且其呈管體之 表面乃都呈平整光滑狀態，導致若欲以手當部推動該手推 部輪圈時，常囚手部帶有水份、油污或出力而流手汗等等， 造成使用者以其手掌部握持該等手推部輪圈時，其手掌部 與該手推部輪圈接觸處之摩擦力大為減低，必須加手掌的 握力才能移動，而造成手部握持久後易酸痛，根本完全不 符合人體工學設計，亟待改進；特別是，因為實際使用輪 椅者’一般不是殘障人士，就是行動不便之體弱人士，此 種設成光滑表面之手推部輪圈結構，往往造成增加使用人 之體力支出’或造成使用上之不便與困難，尤其上坡路段， 倍感吃力，更加在在顯示有其必須再加以改良之急边性。 三、 【新型内容】 •M284371 本創作即是針對前述結構缺點所不盡理相 t w c 4加以再 改良。是以，本創作之主要目的，乃在提 代榷輪椅主輪 之手推部輪圈改良結構，係將手推部輪圈 |付別製.成環狀片 體，而將該環狀片體外周緣表面設成配合 八菔丄學而令使 用者手掌握持推動前進時，可提供舒適握接 〜性忖之圓弧形，其 整體底面環緣，並設以複數個顆粒狀之球體，使手『、 能符合人體工學外，更能增加摩擦力及按摩效果，=: 時不致滑脫及節省握力，實為一進步性、實 ^ μ用性之設計。 四、【實施方式】 餘下，兹再就本案之結構特徵暨操作等項以配合圖 示說明方式，謹述於后，俾提供審查參閱。M284371 捌, new description: First, [the field of new type] The improved structure of the hand wheel rim of the wheelchair main wheel of this case is related to the hand wheel rim of the general wheelchair main wheel, in more detail, how to When the hand-pushing rim is pushed forward, it can provide an ergonomically comfortable grip. 2. [Prior Art] If you are inconvenient in general mobility, you must use a wheelchair to move yourself, so the wheelchair There are a number of auxiliary devices in the main wheel section. Common practitioners will add the structure of the hand-pushing rim to the main wheel of the wheelchair, so that the user's arm can be equipped with a hand-pushing part to provide a hand-pushing force. . In view of the structure of the hand wheel rim of the main wheel of the conventional wheelchair, most of them are made of aluminum alloy or stainless steel which is made of tube body, and the surface of the tube body is flat and smooth, resulting in a smooth and smooth state. If you want to push the hand rim of the hand with your hand, the hand of the prisoner is filled with water, oil or output, and sweat, etc., causing the user to hold the hand rims with the palm of his hand. At the same time, the friction between the palm of the hand and the rim of the hand pushing part is greatly reduced, and the grip strength of the palm must be added to move, and the hand grip is prone to soreness, which is completely ergonomically designed and needs to be improved. In particular, because the actual use of wheelchairs is generally not a person with a disability, or a weak person with limited mobility, this type of hand-pushing rim structure with a smooth surface often results in increased physical exertion of the user' or resulting in use. The inconvenience and difficulty, especially on the uphill section, is more difficult, and it is even more urgent to show that it must be improved. Third, [new content] • M284371 This creation is to refine the tW c 4 for the above structural shortcomings. Therefore, the main purpose of this creation is to improve the structure of the hand wheel rim of the main wheel of the wheelchair, and to push the rim of the hand to make a ring. The outer peripheral surface is designed to cooperate with the gossip to allow the user to grasp and push forward. The circular shape of the comfortable grip can be provided. The overall bottom edge of the ring is provided with a plurality of granular spheres. The hand can be ergonomically enhanced, and the friction and massage effect can be increased. When it is not slipped and the grip is saved, it is a progressive and practical design. IV. [Embodiment] For the rest, the structural features and operations of the case will be described in conjunction with the graphical description.
