Abstract
本發明係包括一下座、二動力源、二第一桿組件、二第二桿組件及一上座。下座具有一虛擬旋轉軸心,二動力源的固定部、二第一桿組件的一端與二第二桿組件的一端皆係樞接於下座。又,上座係同時架設於二動力源的活動部、二第一桿組件的另端與二第二桿組件的另端上。當動力源之活動部位於收回位置,座墊部位於乘坐位置。並當活動部變換至伸出位置,其係推動座墊部以虛擬旋轉軸心為圓心進行旋轉動作,而由乘坐位置變換至一輔助站立位置。故,本案兼具以膝蓋為虛擬旋轉軸心相當符合人體工學,及無滑槽可大幅降低維護與故障的機率等優點。 The present invention comprises a lower seat, two power sources, two first rod assemblies, two second rod assemblies and an upper seat. The lower seat has a virtual rotation axis, and the fixing parts of the two power sources, one end of the two first rod assemblies and one end of the two second rod assemblies are all pivotally connected to the lower seat. Moreover, the upper seat system is erected on the movable part of the two power sources, the other ends of the two first rod assemblies and the other ends of the two second rod assemblies at the same time. When the movable part of the power source is at the retracted position, the seat cushion is at the seated position. And when the movable part changes to the extended position, it pushes the seat cushion part to rotate with the virtual rotation axis as the center of a circle, and changes from the sitting position to an auxiliary standing position. Therefore, this case has the advantages of taking the knee as the virtual rotation axis, which is quite ergonomic, and the absence of chute can greatly reduce the probability of maintenance and failure.
Description
本發明係有關一種輔助站立裝置,尤指一種兼具以膝蓋為虛擬旋轉軸心相當符合人體工學,及無滑槽可大幅降低維護與故障的機率之輔助站立裝置。 The present invention relates to an auxiliary standing device, especially an auxiliary standing device with the knee as the virtual rotation axis, which is quite ergonomic, and has no chute to greatly reduce the probability of maintenance and failure.
按,對於行動不便者或是老年人而言,有時從座椅上站起來(或者是要坐到座椅上),是一件不容易的事,目前具有輔助站立的座椅裝置,共有下列幾種設計: Press, for people with reduced mobility or the elderly, it is not easy to stand up from the seat (or to sit on the seat) sometimes. At present, there are seat devices for assisting standing. The following designs:
1.台灣新型專利第M291289號之具有輔助站立功能的座椅裝置,其重點在於,當控制氣壓棒伸縮時,主要是透過氣壓棒的樞點於坐墊架之導溝內滑動,達成控制座墊架從輪椅本體上升起或降下的功能。 1. Taiwan's new patent No. M291289 for a seat device with an auxiliary standing function. The key point is that when the air pressure rod is controlled to expand and contract, it mainly slides in the guide groove of the cushion frame through the pivot point of the air pressure rod to achieve control of the seat cushion. The function of lifting or lowering the frame from the wheelchair body.
其缺點是:導溝極易髒污,一旦髒污便會影響氣壓棒之樞點移動的順暢性,嚴重的話甚至可能無法升降。 Its disadvantage is: the guide groove is very easy to be dirty, once it is dirty, it will affect the smoothness of the movement of the pivot point of the air pressure rod, and if it is serious, it may even be impossible to lift.
2.台灣發明專利第I465230號之可輔助站立的輪椅,其重點在於,當控制彈推單元伸縮時,除了透過第三樞結組合體推動座椅單元外,尚須透過第一樞接組合體(包括複數零組件),其缺點是相關之連動結構複雜,且操作複雜,對手腳不靈活的行動不便人士來講,可能不方便操作。 2. Taiwan Invention Patent No. I465230 of the wheelchair that can assist standing. The key point is that when controlling the expansion and contraction of the spring push unit, in addition to pushing the seat unit through the third pivot joint assembly, the first pivot joint assembly must also be used to push the seat unit. (including multiple components), the disadvantage is that the related interlocking structure is complicated and the operation is complicated, and it may be inconvenient to operate for handicapped people with inflexible hands and feet.
3.台灣新型專利第M505291號之輔助起身裝置,其主要在於設置二撐高座墊板,但是,二撐高座墊板只可升、降。無法旋轉,而人體坐下與站起,均非單純的升降動作,而是包括以膝蓋為軸心旋轉的動作,故,其設計之缺點是單純升降未能完全輔助人體坐下或是站立。 3. The auxiliary stand-up device of Taiwan's new patent No. M505291 mainly lies in the setting of a two-stay high seat plate, but the two-stay high seat plate can only be raised and lowered. It cannot be rotated, and sitting down and standing up of the human body are not simple lifting movements, but include rotation around the knee as the axis. Therefore, the shortcoming of its design is that the simple lifting cannot fully assist the human body to sit down or stand up.
4.美國專利第2021100411A1號之輔助起身裝置,以及 4. Assisted rising device of US Patent No. 2021100411A1, and
5.關於2011年北科大碩士論文:馬桶輔助站立機構。由於此2設計之缺點相近,故同時簡述如下: 5. About the 2011 Beijing University of Science and Technology Master's Thesis: Toilet Assisted Standing Mechanism. Since the disadvantages of the two designs are similar, they are briefly described as follows:
其缺點包括:[a]椅墊抬升太高,腳踝必須墊高,造成使用者可能要墊腳尖,反而產生站不穩而可能跌倒的危險;[b]坐墊旋轉角度太小;[c]須要設置相當大推力的電動缸,費用相當高。 Its disadvantages include: [a] the chair cushion is raised too high, and the ankle must be raised up, causing the user to step on the toes, which may cause the danger of standing unsteadily and possibly falling; [b] the rotation angle of the seat cushion is too small; [c] it is necessary to It is quite expensive to set up an electric cylinder with a relatively large thrust.
總結前述5種設計之缺點: Summarize the shortcomings of the above five designs:
(a)複接頭部分為滑槽,較容易卡垢,清洗維護不易。 (a) The multiple joint part is a chute, which is easy to get dirty and difficult to clean and maintain.
(b)椅墊抬升太高,大腿角位移也跟著大,腳踝必須墊高,較易造成危險。 (b) If the seat cushion is lifted too high, the angular displacement of the thigh will also be large, and the ankle must be raised, which is more likely to cause danger.
(c)坐墊旋轉角度太小。 (c) The seat rotation angle is too small.
(d)在負重100KG的電動缸推動下桿需求力量較大: (d) The electric cylinder with a load of 100KG needs a lot of power to push the lower rod:
參閱第7A圖,其為前述第5種設計(2011年北科大碩士論文)之機構簡化示意圖,其係設置電動缸GA1,並透過複數連桿GA2推動椅墊GA3。且最終的推力攀升至超過8000牛頓(N)(如第7B圖之第四曲線L4所示的第四推力點M4),導致該電動缸GA1容易耗損。 Refer to Figure 7A, which is a simplified schematic diagram of the mechanism of the aforementioned fifth design (Master's Thesis of Beijing University of Science and Technology in 2011), which is equipped with an electric cylinder GA1, and pushes the seat cushion GA3 through a plurality of connecting rods GA2. And the final thrust rises to over 8000 Newton (N) (the fourth thrust point M4 shown in the fourth curve L4 in FIG. 7B ), which makes the electric cylinder GA1 easy to wear out.
再請參閱第8A圖,其為前述第4種設計(美國專利第2021100411A1號)之機構簡化示意圖,其係設置電動缸GB1,並透過複數連桿GB2推動椅墊GB3。重點是起始推力即需超過12000牛頓(N)(如第8B圖之第五曲線L5所示的第五推力點M5),市售電動缸較難尋得。 Please refer to Figure 8A again, which is a simplified schematic diagram of the mechanism of the aforementioned fourth design (US Patent No. 2021100411A1), which is provided with an electric cylinder GB1, and pushes the seat cushion GB3 through a plurality of connecting rods GB2. The key point is that the initial thrust needs to exceed 12,000 Newtons (N) (the fifth thrust point M5 shown in the fifth curve L5 in Figure 8B), and it is difficult to find commercially available electric cylinders.
有鑑於此,必須研發出可解決上述習用缺點之技術。 In view of this, must develop the technology that can solve above-mentioned conventional shortcoming.

[a]乘坐:如第1A、第1B及第3A圖所示。當該活動部22位於該收回位置P1,該座墊部51係架設於該上端10C,而位於該乘坐位置PA,可供一使用者90乘坐上廁所,此時該使用者90之膝蓋91接近該虛擬旋轉軸心X(也可以說是同軸),且該使用者90之雙腳92係平穩的踩踏於地,可提高穩定性。
[a] Riding: As shown in Figures 1A, 1B and 3A. When the
[b]輔助站立:如第3B至第3C圖所示。控制該活動部22從該收回位置P1變換至該伸出位置P2,該活動部22係推動該座墊部51以該虛擬旋轉軸心X為圓心,對應該上端10C進行旋轉動作,而由該乘坐位置PA變換至該輔助站立位置PB。
[b] Assisted standing: as shown in Figures 3B to 3C. Control the
舉例來講,若該使用者90之體重為100公斤,則由該動力源20與該座墊部51之相對位置(耦桿)所需之推力,可參考第6圖所示的第三曲線L3(對應第3A圖時具有一第一推力點M1)。剛開始所需之推力最大(亦即該第一推力點M1),大約為4796.5牛頓(N),此後需要的推力越來越小(對應第3B圖時具有一第二推力點M2),大約為39146牛頓(N),最後只須大約2990牛頓(N)的推力(對應第3C圖時具有一第三推力點M3)。

亦即,本案係利用電動缸(該動力源20)直接推動椅墊(該座墊部51),除可減少推力分散外,加上該座墊部51係以該使用者90之該膝蓋91做為該虛擬旋轉軸心X,而可以最符合人體工學之站立角度,讓該使用者90之該雙腳92可以平穩踩踏的情況下,於該乘坐位置PA與該輔助站立位置PB之間變換,而可安全的輔助該使用者90在坐下與站立間變換動作。且所有接頭(亦即各樞接部及其樞接裝置)皆以旋轉對相連接與作動(革除公知裝置之導溝或是導槽易髒污,而影響樞接點移動的缺弊)。
That is to say, this case utilizes the electric cylinder (the power source 20) to directly push the seat cushion (the seat cushion part 51), except that the thrust dispersion can be reduced, and the
本發明之特點: Features of the present invention:
(1).構造簡單、無滑槽設計,維護容易。 (1). Simple structure, no chute design, easy maintenance.
(2).利用電動缸直接推動椅墊(耦桿),並以膝蓋位置做為虛擬的旋轉中心(符合人體工學)。 (2). Use the electric cylinder to directly push the chair cushion (coupling rod), and use the knee position as the virtual rotation center (in line with ergonomics).
(3).所有接頭皆為旋轉對。 (3). All connectors are swivel pairs.
(4).電動缸之最大推動力量較小且穩定。 (4). The maximum driving force of the electric cylinder is small and stable.
本發明之優點及功效可歸納如下: Advantage and effect of the present invention can be summarized as follows:
[1]以膝蓋為虛擬旋轉軸心相當符合人體工學。本案之該座墊部係以該虛擬旋轉軸心(亦即使用者之膝蓋)為圓心,對應該下座轉動,而可以最符合人體工學的角度,於該乘坐位置與該輔助站立位置之間變化,進而在使用者雙腳平穩踩踏的情況下,用以輔助在乘坐與站立之間變換。故,以膝蓋為虛擬旋轉軸心相當符合人體工學。 [1] Taking the knee as the virtual axis of rotation is quite ergonomic. In this case, the seat cushion is centered on the virtual rotation axis (that is, the user's knee), and rotates corresponding to the lower seat, so that it can be positioned between the sitting position and the auxiliary standing position at the most ergonomic angle. It can be used to assist the transition between sitting and standing when the user's feet are pedaling smoothly. Therefore, taking the knee as the virtual axis of rotation is quite ergonomic.
[2]無滑槽可大幅降低維護與故障的機率。本案之所有樞接部與相關之樞接元件,皆為"旋轉對"設計,大幅減少公知裝置因滑槽髒污而需維護或甚至故障而無法操作的機率。故,無滑槽可大幅降低維護與故障的機率。 [2] No chute can greatly reduce the probability of maintenance and failure. All the pivot joints and related pivot joint elements in this case are designed as "rotating pairs", which greatly reduces the probability of conventional devices being inoperable due to dirty chutes requiring maintenance or failure. Therefore, no chute can greatly reduce the probability of maintenance and failure.
