Description
本發明是有關於一種適用於照護病人或不便行動人士的照護工具,特別是指一種輪椅。The present invention relates to a care tool suitable for caring for patients or people with mobility impairments, in particular to a wheelchair.
目前現有的輪椅,大多包含一椅座單元、一裝設在該椅座單元底部的椅輪單元、兩個分別由該椅座單元的左右兩側往上突伸的扶手單元,以及一個由該椅座單元後端往上突伸的椅背單元。Currently, most existing wheelchairs include a seat unit, a wheel unit installed at the bottom of the seat unit, two armrest units protruding upward from the left and right sides of the seat unit, and an armrest unit extending upward from the left and right sides of the seat unit. The back unit protrudes upward from the rear end of the seat unit.
該椅座單元適用於供一使用者乘坐。該椅輪單元可供該輪椅在地面上移動。該等扶手單元及該椅背單元固定在該椅座單元上,以支撐並防護該使用者。The seat unit is suitable for one user to sit on. The wheelchair wheel unit allows the wheelchair to move on the ground. The armrest units and the chair back unit are fixed on the seat unit to support and protect the user.
此種現有的輪椅雖已行之有年,但仍有其不足之處。例如,當該使用者幾乎沒有自主行動能力時,如欲將該使用者挪移至病床或者手術、檢查平台時,通常需要將該使用者整個抱起,才能移動到目標位置,然而將該使用者整個抱起,除了力氣需要足夠大外,也需要技巧、巧勁,非專業照護人員可能因操作不慎而傷及自身,甚至摔傷該使用者,不可不慎。Although this kind of existing wheelchair has been in use for many years, it still has its shortcomings. For example, when the user has almost no ability to move independently, if you want to move the user to a hospital bed or a surgical or examination platform, you usually need to lift the user completely to move to the target location. However, the user must be moved to the target location. Lifting the whole thing requires not only sufficient strength, but also skills and dexterity. Non-professional caregivers may injure themselves or even fall and injure the user due to careless operation, so do not be careless.
本發明的目的在於:提供一種能夠改善先前技術的至少一個缺點的輪椅。The object of the present invention is to provide a wheelchair that improves at least one of the shortcomings of the prior art.
該輪椅適用於供一使用者乘坐使用,並適用於供該使用者移動至一支撐面。該輪椅包含一椅座單元、一椅輪單元,以及兩扶手單元。The wheelchair is suitable for a user to ride on, and is suitable for the user to move to a supporting surface. The wheelchair includes a seat unit, a wheel unit, and two armrest units.
該椅座單元包括一椅面。該椅面能在一個橫向延伸而適用於供該使用者乘坐使用的乘坐狀態,變換至一個傾斜延伸的傾斜狀態。該椅輪單元裝設在該椅座單元底部。每一所述扶手單元樞接在該椅座單元左右兩側的其中一側。該等扶手單元的其中至少一者能由一個直立狀態,相對該椅座單元往遠離該椅面的方向樞擺,而變換至一個橫擺狀態,進而適用於與該椅面相配合支撐該使用者移動至該支撐面。The seat unit includes a seat surface. The seat surface can be extended in a transverse direction and adapted to a sitting state for the user to sit on, and can be transformed into an inclined state in which the seat surface is extended obliquely. The chair wheel unit is installed at the bottom of the chair seat unit. Each armrest unit is pivotally connected to one of the left and right sides of the seat unit. At least one of the armrest units can be pivoted from an upright state in a direction away from the seat surface relative to the seat unit, to a swaying state, and is further adapted to cooperate with the seat surface to support the user. Move to this support surface.
本發明的功效在於:該椅面與其中一個所述扶手單元能分別變換至該傾斜狀態與該橫擺狀態,因此能利於該使用者倒向該扶手單元,並以該扶手單元支撐該使用者,進而利於該使用者移動到該支撐面上。The effect of the present invention is that the chair surface and one of the armrest units can be transformed into the tilted state and the swaying state respectively, thereby facilitating the user to lean towards the armrest unit and supporting the user with the armrest unit , thereby facilitating the user to move to the support surface.
參閱圖1至3,本發明輪椅的一個實施例,適用於供一使用者乘坐使用,並適用於供該使用者移動至一支撐面1(見圖4)。所述的支撐面1舉例來說為臥床或病床之床面,或擔架之承載面。Referring to Figures 1 to 3, one embodiment of the wheelchair of the present invention is suitable for a user to ride on and for the user to move to a support surface 1 (see Figure 4). The supporting
本實施例包含一個適用於供該使用者乘坐的椅座單元2、一個固定連接在該椅座單元2後端的椅背單元3、一個裝設在該椅座單元2底部的椅輪單元4,以及兩個分別樞接在該椅座單元2左右兩側的扶手單元5。This embodiment includes a
該椅座單元2包括一椅座架21、數個設置在該椅座架21上的樞接架22、數個底部分別樞接該等樞接架22的伸縮組23、數個設置在該等樞接架22與該等伸縮組23間的彈性件24,以及一個設置在該等伸縮組23上的乘坐組25。The
該椅座架21包括兩支左右間隔且前後延伸的底座桿211、一塊呈矩形板狀並架設在該等底座桿211上的底座板212、四支分別由該底座板212往上延伸的直座桿213、四支設置在該等直座桿213頂端並相配合排列呈方環狀的頂座桿214,以及兩支分別由前後延伸的其中兩支所述頂座桿214往前下方傾斜延伸的腳踏桿215。其中,因為視角關係,其中一支所述直座桿213與其中一支所述頂座桿214被該乘坐組25遮擋住,因此圖1中僅顯示其中三支。The
該等樞接架22用以分別供該等伸縮組23設置在該椅座架21上。每一樞接架22包括一個固定在該底座板212上的底壁部221,以及兩個分別由該底壁部221的前後兩端往上延伸的側壁部222。每一樞接架22的該底壁部221與該等側壁部222相配合使該樞接架22由左右方向看呈U形。The
每一所述伸縮組23透過樞接各別的一個所述樞接架22而設置在該椅座架21的該底座板212上,並包括一個底部樞接各別的一個所述樞接架22的該等側壁部222的伸縮本體231,以及一個能往上突出或往下縮入該伸縮本體231的伸縮件232。Each
其中,該等伸縮組23在橫向方位上,位於該等頂座桿214所構成的方環內,因此每一伸縮件232往上突伸時,插設進該等頂座桿214所圍繞構成的方環中。Among them, the
在本實施例中,每一伸縮組23為一氣壓缸。因此,每一所述伸縮本體231為氣壓缸的缸體,每一所述伸縮件232為氣壓缸的(活)塞桿。在本發明的其他實施態樣中,每一伸縮組23也能為液壓缸或伸縮桿組。所述的液壓缸可為手動或自動。所述的伸縮桿組可以包括一根以電機驅動的伸縮桿,或者包括能以螺紋結構驅動且能以手動驅動的螺桿。In this embodiment, each
在本實施例中,該等伸縮組23的數量為四個,且兩個一群地分為左右兩群。每一群的該等伸縮組23位於該椅座架21的該底座板212左右兩側的其中一側。也就是說,該椅座架21的左右兩側的每一側設置有兩個所述伸縮組23。In this embodiment, the number of the
在本發明的其他實施態樣中,該等伸縮組23的數量也能為六個以上或更多。也就是說,該椅座架21的左右兩側的每一側可以設置有三個以上的伸縮組23,以進一步提高本實施例的載重與作動負荷。In other embodiments of the present invention, the number of
每一彈性件24連接在各別的一個所述伸縮組23的該伸縮本體231底部與該樞接架22的該底壁部221上下之間。Each
該乘坐組25樞接設置在該等伸縮組23的該等伸縮件232頂端,並界定出一個位於頂端且適用於供該使用者乘坐的椅面251。該乘坐組25舉例來說可包括一塊硬質的座板、一塊設置在該座板上且軟質的座墊,以及一片包覆在該座板與該座墊外的表皮或表布。由於該乘坐組25的結構屬於通常知識,故圖中省略示意。The
該椅背單元3包括兩根左右間隔而分別固定在該椅座單元2的其中兩支前後延伸的所述頂座桿214後端的椅背桿31,以及一塊左右延伸地張設在該等椅背桿31上的椅背布32。每一椅背桿31概呈倒L形。每一椅背布32適用於支撐該使用者的背部。The
該椅輪單元4包括四顆移動輪41。該等移動輪41兩個為一組。每一組的該等移動輪41彼此前後間隔地樞接該椅座架21的其中一支底座桿211。該等移動輪41用以相配合供本實施例於地面上移動。The
每一所述扶手單元5包括兩根上下延伸且前後間隔地樞接該椅座架21的其中一支前後延伸的所述頂座桿214的樞接桿51、一支前後延伸地一體連接於該等樞接桿51頂端支間的扶手桿52、數支上下間隔排列且前後延伸地樞接於該等樞接桿51間的輥子53,以及一個能分離地插設在位於後方的其中一支所述樞接桿51與該椅背單元3各別的一支椅背桿31的插銷組54。每一所述輥子53能以自身前後延伸的軸線為旋轉軸心轉動。Each of the
參閱圖1、3、4,本實施例的該椅面251能在一個如圖1、3所示的乘坐狀態與一個如圖4所示的傾斜狀態間變換,且本實施例的每一扶手單元5能在一個如圖1、3所示的直立狀態,以及一個如圖4所示的橫擺狀態間變換。其中,由於該等扶手單元5的作動方式相同,因此於圖4中僅以其中一者作為代表示意。Referring to Figures 1, 3, and 4, the
當該椅面251處於該乘坐狀態而橫向延伸,且該等扶手單元5處於該直立狀態時,本實施例便如同一般的輪椅,能以該乘坐組25支撐該使用者的臀部,並能以該等扶手單元5支撐該使用者的雙手,同時該椅背單元3可支撐該使用者的背部。When the
以該使用者有被往圖面右方移動到該支撐面1上的需求為例說明,可先拔掉位於圖面右方的該插銷組54,使位於圖面右方的該扶手單元5往相背遠離該椅面251的方向(即往圖面右方)樞擺而變換至如圖4所示的該橫擺狀態,並先抵靠在該支撐面1上。Taking the user's need to be moved to the right side of the figure onto the
接著,位於圖面左側的該等伸縮件232能分別突伸出對應的該等伸縮本體231,從而使該乘坐組25整體於圖面中左高右低地傾斜,進而使該椅面251變換至傾斜延伸的斜度大於該乘坐狀態的傾斜狀態。如此一來,原本位於該椅面251上的該使用者,在該椅面251變換的過程中,可逐漸且自然地往圖面右方的該扶手單元5倒躺。Then, the
由於位於圖面右方的該扶手單元5的該等輥子53能以自身軸線為旋轉軸心轉動,因此照護該使用者的一照護者,在該等樞接桿51與該扶手桿52的支撐下,並在該等輥子53的轉動配合下,無需高度專業技巧與太大的力氣,便能將該使用者沿著該扶手單元5往右橫向移動至該支撐面1上,也就是能將該使用者移動至病床或擔架上,相當方便。Since the
其中,由於每一伸縮組23樞接各別的一個所述樞接架22與該乘坐組25,因此在每一伸縮件232突伸出各別的一個所述伸縮本體231時,該伸縮組23整體能相對該椅座架21傾斜樞擺,以使該椅面251能滑順地在該乘坐狀態與該傾斜狀態間變換。Among them, since each
當使用者被移動到該支撐面1上後,該等伸縮件232可再次分別縮入該等伸縮本體231中,以使該椅面251回復至該乘坐狀態,接著將該扶手單元5擺正回該直立狀態並插回該插銷組54,本實施例即回復至一般輪椅的狀態。其中,該等伸縮件232分別縮入該伸縮本體231的過程中,該等彈性件24能輔助將該等伸縮本體231分別朝該等樞接架22拉回,從而可協助該等伸縮本體231擺正。After the user is moved to the
綜上所述,本發明輪椅的功效在於:該椅面251與所述扶手單元5能分別變換至該傾斜狀態與該橫擺狀態,因此能利於該使用者倒向該扶手單元5,並以該扶手單元5支撐該使用者,進而利於該使用者移動到該支撐面1上。To sum up, the effect of the wheelchair of the present invention is that the
