Description
本發明係隸屬一種助行器之技術領域,具體而言係指一種可減輕使用負荷的助行器之結構改良,藉以能提升使用的便利性。The invention belongs to the technical field of a walker, in particular to a structural improvement of a walker which can reduce the use load, thereby improving the convenience of use.
按,助行器之發展主要係為了幫助一些下肢喪失部分功能的人們使用,如:年長者、身體障礙或是身體虛弱者,藉由助行器可將部分體重經由上肢轉移到助行器上,而減輕下半身的負擔,以利行走。因此,市面上為了因應此需求發展出各式各樣功能的助行器。一般市面上的助行器有很多種,如:固定型、折疊型、交替型、帶輪型及後拉型等助行器。According to the development of the walker, it is mainly used to help some people whose lower limbs lose some functions, such as the elderly, physical disabilities or the weak, and the part of the weight can be transferred to the walker via the upper limb by the walker. And reduce the burden on the lower body to facilitate walking. Therefore, in order to develop this kind of function, the walker is developed in response to this demand. There are many types of walking aids on the market, such as fixed type, folding type, alternating type, pulley type and rear pull type.
各類助行器因結構及功能設計差異,各有其不同的需求,而本發明所欲討論者係其簡易之固定型助行器,現有固定型助行器係由兩相對之ㄇ型腳架所構成,並於兩腳架的側邊及前側分設有至少一側支桿與至少一前支桿,使助行器由俯視觀之形成可供使用者站於其中之ㄈ形框體,讓使用者利用助行器輔助行走時,可站立於助行器內,並以雙手握住兩側腳架之頂桿段,提起助行器向前移動,再將助行器以腳架定位於地面後,經由雙手施力帶動身體向前行走;然而,由於使用者均係屬老弱傷殘,長時間使用容易造成雙手負擔,且對於雙手亦無法施力及活動不便時,雖然仍可勉強因助行器輔助行走,但必須耗費更多的 力氣,仍有不便利之處。雖然目前市面上設計有帶輪型助行器,可減輕使用者移動的負荷,但其需加裝煞車機構,不僅結構複雜、成本高,且使用過程中使用者需不斷的按壓及釋放煞車把手,反而造成操作上的不便,更甚者,當煞車機構異常時,使用者是無法立即反應,因而無法以該煞車機制來煞住助行器,於此,使用者容易發生摔倒而使身體受到嚴重傷害的情事發生。All kinds of walkers have different needs due to differences in structure and function design, and the present inventors want to discuss their simple fixed type walkers. The existing fixed type walkers are made up of two opposite type of feet. The frame is formed, and at least one side strut and at least one front strut are respectively disposed on the side and the front side of the bipod, so that the walker forms a dome-shaped frame that can be stood by the user in a plan view When the user uses the walking aid to assist walking, he can stand in the walking aid, and hold the ejector section of the two side legs with both hands, lift the walking aid forward, and then use the footer to the foot. After the frame is positioned on the ground, the body is forced to move forward by the force of both hands; however, since the users are old and weak, the long-term use is easy to cause the burden on both hands, and the hands are unable to exert force and the movement is inconvenient. At the same time, although it is still barely able to assist walking by the walker, it must consume more Strength, there are still inconveniences. Although the wheeled walker is designed on the market to reduce the user's mobile load, it needs to be equipped with a brake mechanism, which is not only complicated in structure, high in cost, but also needs to be constantly pressed and released by the user during use. On the contrary, it causes inconvenience in operation. What is more, when the brake mechanism is abnormal, the user cannot immediately respond, and thus the brake device cannot be used to hold the walker. Therefore, the user is prone to fall and the body is easily broken. A serious injury occurs.
換言之,現有助行器因無法兼具減輕負荷及易於操作之效果,而造成使用上或因負荷大無法有效移動、又或因煞車異常存在危險性等困擾與不便,而無法滿足實際使用的需求,有待進一步的改良。In other words, the existing walker cannot meet the needs of actual use because it cannot be combined with the effect of reducing the load and being easy to operate, and the use or the load cannot be effectively moved, or the risk of the brake is abnormal. Further improvements are needed.
有鑑於此,本發明人乃針對前述習式助行器在使用時所面臨的問題深入探討,並藉由多年從事相關產業的研發與製造經驗,經不斷努力的改良與試作,終於成功開發出一種助行器之結構改良,藉以克服現有者無法兼具減輕負載及安全性所造成的不便與困擾。In view of this, the present inventors have intensively discussed the problems faced by the aforementioned walker in use, and have succeeded in developing through continuous improvement and trial work through years of experience in research and development and manufacturing of related industries. A structure improvement of a walker to overcome the inconvenience and trouble caused by the inability of both of them to reduce load and safety.
因此,本發明之主要目的係在提供一種助行器之結構改良,藉以能有效減輕移動助行器的負荷,且能避免其因煞車異常而無法有效定位的問題,大幅增進使用的便利性及安全性。Therefore, the main object of the present invention is to provide a structure improvement of a walker, thereby effectively reducing the load of the mobile walker, and avoiding the problem that the vehicle cannot be effectively positioned due to the abnormality of the brake, thereby greatly improving the convenience of use and safety.
