M422.965 五、新型說明： 【新型所屬之技術領域】 本創作係關於一種助行裝置，特別係指一種寬度可 調式助行裝置。 【先前技術】 助行裝置為行動不便者常需使用的裝置，一般會建 議行動不便者暫時或永久使用助行裝置的原因不外乎 因疾病或外傷導致肌力不足或平衡感較差。而身體機能 慢慢退化的老年人，也常常被建議使用助行裝置以增加 行動的穩定性。使用助行裝置行走最常被提到與所公認 的優點，是為可增加支撐底面積，以幫助平衡能力較差 的患者行走，另外為可利用上肢支撐力以協助下肢支撐 身體的重量，而減輕下肢肌肉負擔，避免因下肢肌肉力 量不足而跌倒。 進行助行裝置設計時，必須考慮使用者與助行裝置 結合之系統性架構，包含：助行裝置本身的設計（如寬 度、高度、輪腳的種類）、使用者本身的體型、能、力（如 身高、肩寬、手腳長度、平衡能力與反應、及體能與疾 病狀況等）、以及行動環境的地形（如斜坡、上下階梯 等），每一個要素皆會影響助行裝置之適用性及操作表 現。 目前大多數習知的助行裝置，例如第1圖所示， M422965 習知助行裝置100苴官疳θ m ^ 八見度疋固疋不變的而其高度是可 調整的。所以目前市面上是崎供不同寬度之助行裝置 的方式以供使用者選擇購買。 【新型内容】 本創作所欲解決之技術問題 目前的助行裝置在市射係分絲種寬度類型供 使=者選擇，而各類寬度類型的助行裝置其之間有一定 的寬度差距。因此，使用者可選擇的助行裝置寬度類型 有限’因*可選擇到寬度最為精確合適之機率也較小。 另外當❹者使用助行裝置時，也無法機動性地根據不 同地形而改變助行裝置的寬度，以配合運用最適合的骨 骼關節角度以便於施力。所以，除了目前助行裝置已具 有的高度可調整功能之外，更進一步設計寬度可調整的 助行裝置顯得極為重要。為了使肌力不足或身體虛弱的 使用者易於自主性地調整助行裝置，可調式助行裝置設 計必需考慮到調整的簡便性。而為了讓使用者安全而穩 疋地使用助行裝置，所以助行裝置其可調整之結構部份 的δ又计則必須更為加強考量結構之堅固及穩定性。 緣此，本創作之目的即是提供一種兼具調整便利 性及結構之堅固及穩定性的寬度可調式助行裝置，讓使 用者可根據本身的體型能力及所活動的環境地形適切 地調整助行裝置的寬度。 4 本創作解決問題之技術手段

New description: [New technical field] This creation is about a walking aid, especially a width adjustable living aid. [Prior Art] The walking aid is a device that is often used by people with reduced mobility. It is generally recommended that the temporary or permanent use of the walking aid for persons with reduced mobility is caused by insufficient muscle strength or poor balance due to illness or trauma. Older people whose body functions are slowly degrading are often recommended to use mobility devices to increase the stability of their actions. The most commonly mentioned and recognized advantages of walking with walking aids are to increase the support floor area to help patients with poor balance, and to use the upper limb support to assist the lower limbs in supporting the weight of the body. The lower limb muscles are burdened to avoid falling due to insufficient muscle strength in the lower limbs. When designing the walking device, the system architecture of the user and the walking device must be considered, including: the design of the walking device itself (such as width, height, type of casters), the user's own body shape, energy, and force. (such as height, shoulder width, length of hands and feet, balance and reaction, physical and disease status, etc.), and the terrain of the action environment (such as slopes, steps, etc.), each of which affects the applicability of the mobility aid and Operational performance. At present, most of the conventional walking aids, such as shown in Fig. 1, M422965 conventional walking aids 100 苴 m m ^ 八 疋 疋 而 而 而 而 而 而 而 而 而 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 Therefore, the current market is a way to provide different widths of walking aids for users to choose to purchase. [New content] The technical problems to be solved by this creative work The current walking aids are selected in the type of width of the city, and the width of the various types of walking devices have a certain width difference. Therefore, the type of width of the walker that the user can select is limited. The probability of selecting the most accurate and appropriate width is also small. In addition, when the wearer uses the walking device, it is also impossible to flexibly change the width of the walking device according to different terrains to match the most suitable bone joint angle to facilitate the application of force. Therefore, in addition to the highly adjustable functions that the current walking aids already have, it is extremely important to further design a width-adjustable walking aid. In order to make it easy for the user with insufficient muscle strength or weakness to adjust the walking device autonomously, the adjustable walking device design must take into account the ease of adjustment. In order to allow the user to use the walking aid safely and steadily, the δ of the adjustable structural part of the walking device must be more robust to the stability and stability of the structure. Therefore, the purpose of this creation is to provide a width-adjustable walking device that combines the convenience and stability of the structure with the stability and stability of the structure, so that the user can appropriately adjust the shape according to his body shape and the environment in which he or she moves. The width of the line device. The technical means for solving the problem of the prior art is a width adjustable walking device comprising a first auxiliary supporting member, a second auxiliary supporting member and a width adjusting mechanism. . The width adjustment mechanism is coupled to the first auxiliary support member and the second auxiliary support member, and the width adjustment mechanism includes a first # rail member, a second tooth member, and a first rack member and a second tooth holder a rotating member between the members. When the rotating member is rotated in a rotational direction, the first rack member and the second tooth member are respectively biased by the rotating member to bring the first auxiliary supporting member and the second auxiliary supporting member closer to each other. Wherein, when the rotating member is rotated in a direction opposite to the direction of rotation, the first rack member and the second rack member are respectively biased by the rotating member to move the first auxiliary supporting member and the second auxiliary supporting member away from each other. In an embodiment of the present invention, the rotating member has a gear that meshes with the first and second rack members and a knob that is coaxially coupled to the gear. In an embodiment of the present invention, a cover is further included, and is disposed on the first rack member and/or the second rack member of the width adjusting mechanism. In an embodiment of the present invention, wherein the rotating member has a shaft column, the cover body has a width limiting hole extending along a relative displacement direction of the first auxiliary supporting member and the second auxiliary supporting member, and the shaft column is movably worn through the M4229. .65 is placed in the width limit hole and displaced in the range of the width limit hole. In an embodiment of the present invention, wherein the width adjusting mechanism further comprises a width locating member. In an embodiment of the present invention, the width positioning member includes a sliding seat coupled to the rotating member, a positioning rod movably disposed in the sliding seat, and a plurality of spaced apart formations on the first rack member or the second The positioning port of the rack member is correspondingly engaged with the selected positioning port to position the rotating member with the first tooth holding member and the second tooth holding member. In an embodiment of the present invention, wherein the first auxiliary support member and the width adjusting mechanism and/or the second auxiliary supporting member and the width adjusting mechanism are coupled by a rotating shaft mechanism. In an embodiment of the present invention, the invention further includes a rotation limiting mechanism including a link member and a stop member, the link member having a rotating portion rotatably coupled to the width adjusting mechanism, and a sliding joint a sliding portion of the first auxiliary supporting member or the second auxiliary supporting member, the stopping member being provided to be coupled in the sliding portion to fasten or relax the sliding portion at a specific position of the first auxiliary supporting member or the second auxiliary supporting member . In an embodiment of the present invention, the first auxiliary support member and the second auxiliary support member each have a post height adjustment member. This creation is based on the technical means used in this creation. In addition to the general aid 6 M.422.965, a width adjustment mechanism is added to enable the walking device to adjust the width to the most. It is suitable for the individual body's body ability and the active terrain to achieve the optimization of human mechanics. By using the rotating member and the rack member of the width adjusting mechanism of the present invention, the user only needs to move the end of the limbs such as the hand rotation when adjusting the width, instead of directly using the body arm and the shoulder joint activity. The action is to stretch or press the lateral width members of the walking aid. Therefore, the width adjustment of the creation is simple and does not require too much physical strength, and is very important for users with insufficient muscle strength or weakness, and further enhances the mobility of the walking device that may need to be adjusted at any time to adapt to environmental changes. . Furthermore, all the members of the width adjustment mechanism of the present invention correspond to each other in the center of gravity and the position, and the joint force distribution between the members is averaged, so that the structure of the width-adjustable walking device is fairly balanced and stable, so that the user There is no need to worry about the fact that the mobility aid cannot withstand the forces and the center of gravity. Due to the structural stability, a dense width positioning port can be added to make the width of the width adjusting mechanism fine-tuned and more suitable for the user. And the design of the positioning structure is firm and reliable, so that the user does not have to worry about the problem of poor positioning. The rotation limit mechanism makes it easier for the user to fold the walking device without using the walking device. Therefore, the width-adjustable walking device of the present invention can meet the mobility and stability emphasized by the rehabilitation aids, and is further suitable for the use of patients with lower limb disability, body balance disorder or weakness to enhance their daily routine. The ability and autonomy of the activity. The specific embodiments used in the present application will be further illustrated by the following examples and accompanying drawings.
