Description

可收摺踏板的輪椅(四)Wheelchair with folding pedal (4)

本創作是有關於一種輪椅,特別是有關於一種收摺方式更為簡易快速的可收摺踏板的輪椅(四)。This creation is about a wheelchair, especially a wheelchair (4) that is easier and faster to fold off the pedal.

隨著社會人口高齡化時代的來臨,人們對於家中老人與病患的照顧,也相對的需付出更多的心力與時間,以短程的運送代步工具---「輪椅」而言,係屬常見的運輸椅具之一,因此市面上也已開發出各種類型的輪椅,以滿足不同使用者的需求。With the advent of the ageing society, people have to pay more attention to the care of the elderly and the sick at home. In the case of short-distance transport means, "wheelchairs", it is common. One of the transport chairs, so various types of wheelchairs have been developed on the market to meet the needs of different users.

其中,基於方便攜帶及空間收納的考量,又以可折疊式的輪椅最為一般消費者所接受,這種可折疊式的輕便輪椅大致上是在二個呈對稱的骨架之間,樞設了有一個呈X型的折合架,且每個骨架的後方底部各裝了一個主輪,而骨架前方底部則裝設有小輪徑的從動輪,並且兩個骨架之間水平的設置了一個座墊,而骨架後上方再對應主輪又豎立有一椅背桿,椅背桿的頂端裝設有一推把,且兩個椅背桿之間可供套置一椅背墊,另外,每個骨架上又設有一扶手,而各骨架前方則分別一體彎折延伸出有一扶腳桿,該扶腳桿末端樞接有一腳踏板,該腳踏板可以被旋轉擺動成水平與立起狀態,藉此,當老人或患者乘座於該座墊上時,便可將背部倚靠於椅背墊,雙手則扶置於扶手,而雙腳則踏置在腳踏板上,使看護人員能握持著推把來推移輪椅。Among them, based on the convenience of carrying and space storage considerations, it is accepted by the most common consumers of foldable wheelchairs. The foldable lightweight wheelchair is roughly between two symmetrical skeletons. An X-shaped folding frame, and each main frame has a main wheel at the bottom of the rear, and a small wheeled driven wheel is arranged at the bottom of the front of the frame, and a seat cushion is horizontally disposed between the two frames. And the back of the skeleton corresponding to the main wheel is erected with a backrest bar, the top of the backrest bar is provided with a push handle, and a backrest pad can be placed between the two backrest bars, and, on each skeleton Further, a handrail is arranged, and a front leg of each frame is integrally bent and extended, and a footrest is pivotally connected to the end of the footrest. The foot pedal can be rotated and swinged into a horizontal and vertical state. When the old man or the patient is seated on the seat cushion, the back can be rested on the back cushion, the hands are placed on the handrail, and the feet are placed on the pedals, so that the caregiver can hold Push the handle to move the wheelchair.

而當輪椅須長途運送或收納時,便可利用輪椅的折合架的可 折合結構,使兩骨架的間距縮小,以縮小整個輪椅的體積,俾便於運送。When the wheelchair has to be transported or stored for a long distance, the folding frame of the wheelchair can be used. The folding structure reduces the spacing between the two skeletons to reduce the volume of the entire wheelchair and facilitate transportation.

雖然,以往的可折疊式輪椅具有骨架可水平縮移的功能,但是仍存在著一些問題,即,雖然吾人可將腳踏板翻折後呈立起狀,以形成一立足空間,以便於乘座者的乘座或離座,但是立起的腳踏板與延伸至骨架前方的扶腳桿,仍呈凸出於骨架前而形成一障礙,如此一來,將不利於乘座或離座時的動線,且更重要的是,凸出的扶腳桿與腳踏板無法朝骨架內來收摺,恐因佔用過大的空間,以致於無法將輪椅放置入汽車的後行李箱內運送。Although the conventional foldable wheelchair has the function of horizontally retracting the skeleton, there are still some problems, that is, although the person can fold the foot pedal and stand up to form a foot space for easy riding. The seat of the seat is seated or left, but the raised foot pedal and the foot stick that extends to the front of the skeleton still form a barrier protruding from the front of the frame, which will not be advantageous for riding or leaving the seat. The moving line and, more importantly, the protruding footrests and pedals cannot be folded into the skeleton, which may cause too much space to be placed in the trunk of the car. .

所以,目前這類型的輪椅只能將扶腳桿與腳踏板一體自骨架上卸下,才不致造成包裝及搬運上的阻礙,但卸下後的扶腳桿與腳踏板還要另外收放,不僅麻煩且有遺失的可能,也同樣會產生收藏及運送上的困擾,另一方面,對於老人或患者而言,勢必不能自行再將扶腳桿組立於骨架上,仍必須完全仰賴他人代勞。Therefore, at present, this type of wheelchair can only remove the footrest and the foot pedal from the skeleton, so as not to cause obstacles in packaging and handling, but the footrest and the pedal are removed after the removal. Putting it, not only troublesome, but also the possibility of loss, it will also cause troubles in collection and transportation. On the other hand, for the elderly or patients, it is bound to be able to stand on the skeleton by themselves, and still have to rely entirely on others. On behalf of the work.

本創作的可收摺踏板的輪椅(四),將踏板組收摺至座墊上方,而被座墊、背墊及扶手所包覆,使得收摺後的輪椅體積縮至更小,且外觀更紮實感,收摺方式更簡便快速之外,也有利於搬移與運送。The wheelchair (4) of the created folding pedal folds the pedal group above the seat cushion, and is covered by the seat cushion, the back pad and the armrest, so that the folded wheelchair volume is reduced to a smaller size and appearance. It is more solid and easy to move and transport.

參照第2圖及第3圖所示,該樞結件91,具有一基壁911、 一第一側壁912、一第二側壁913、一貫穿該第一側壁912與第二側壁913的穿孔914,以及一由該基壁911、第一側壁912、第二側壁913所界定出的開放槽915,且該第一側壁912上設有一與該穿孔914相連通的圓形孔槽916,該第二側壁913上設有一與該穿孔914相接通的六角孔槽917。組裝時,將該螺帽942安置在該第二側壁913的六角孔槽917內,該螺桿941則穿入該圓形孔槽916、穿孔914,再穿入於該六角孔槽917內,並與該螺帽942相互鎖固,以藉由該鎖接組件94將該樞結件91鎖固在該前豎桿13的中段處。當該踏板組80的樞轉部83已藉由鎖接組件94樞設在該樞結件91上,此時該主體桿81呈樞接狀態與樞結件91相連接,且螺帽942已限位在該六角孔槽917內部,所以,當旋轉該踏板組80時,樞轉中的主體桿81並不會連動到該螺桿941與螺帽942的緊配合關係,亦即,藉由該六角孔槽917讓螺帽942獲得安全定位,即可避免樞轉活動影響到該踏板組80與該樞結件91的連接關係,因此,其螺帽942不會受外力鬆動,故可確保該主體桿81牢實定位於該樞結件91上,而不致產生鬆脫之意外。Referring to Figures 2 and 3, the pivoting member 91 has a base wall 911, a first sidewall 912, a second sidewall 913, a through hole 914 extending through the first sidewall 912 and the second sidewall 913, and an opening defined by the base wall 911, the first sidewall 912, and the second sidewall 913 The first side wall 912 is provided with a circular hole 916 communicating with the through hole 914. The second side wall 913 is provided with a hexagonal hole 917 connected to the through hole 914. When assembled, the nut 942 is disposed in the hexagonal hole 917 of the second side wall 913, and the screw 941 penetrates into the circular hole 916, the through hole 914, and penetrates into the hexagonal hole 917, and The nut 942 is interlocked with the nut 942 to lock the pivoting member 91 at the middle portion of the front vertical rod 13 by the locking assembly 94. When the pivoting portion 83 of the pedal group 80 is pivotally mounted on the pivoting member 91 by the locking assembly 94, the main body rod 81 is pivotally connected to the pivoting member 91, and the nut 942 has been The position is limited to the inside of the hexagonal hole slot 917. Therefore, when the pedal group 80 is rotated, the pivoting main body rod 81 does not interlock with the screw 941 and the nut 942, that is, by the The hexagonal hole slot 917 allows the nut 942 to be securely positioned to prevent the pivoting activity from affecting the connection relationship between the pedal set 80 and the pivoting member 91. Therefore, the nut 942 is not loosened by the external force, thereby ensuring the The body rod 81 is firmly positioned on the pivoting member 91 without causing an accident of loosening.

如第4、5圖所示,該第一夾持件92,包含有一基礎部921、二個自該基礎部921兩側向外延伸之爪形側壁922,及一位於兩爪形側壁922之間的圓弧槽923。利用螺桿941與螺帽942之配合,得以將該第一夾持件92鎖固定在該前豎桿13的底段處。在使用狀態,是將該踏板組80的主體桿81擠入於該圓弧槽923內,而被兩爪形側壁922所夾固,即可令該踏板組80維持定位在該前豎桿13前方,以供承載使用者的腳部。As shown in FIGS. 4 and 5, the first clamping member 92 includes a base portion 921, two claw-shaped side walls 922 extending outward from both sides of the base portion 921, and a claw-shaped side wall 922. An arc groove 923 between. The first clamping member 92 is locked and fixed to the bottom portion of the front vertical rod 13 by the cooperation of the screw 941 and the nut 942. In the state of use, the main body rod 81 of the pedal group 80 is squeezed into the circular arc groove 923, and is clamped by the two claw-shaped side walls 922, so that the pedal group 80 can be maintained positioned on the front vertical rod 13 Front to carry the user's foot.

該第二夾持件93,是一固定在該前豎桿13前端的塞件,並具有一供包夾該踏板組80之主體桿81桿身的圓凹槽931。The second clamping member 93 is a plug fixed to the front end of the front vertical rod 13 and has a circular groove 931 for clamping the shaft of the body rod 81 of the pedal group 80.

因此,當該輪椅的椅架10已藉由該折合單元20及活動關節15分別收摺之後,如第4、5圖所示,各該踏板組80的收摺方式,是直接將該主體桿81拉離該第一夾持件92的圓弧槽923後,再將該踏板組80向 上樞轉,此時該踏板組80經旋轉而收置在該座墊30上方,並藉由該第二夾持件93的圓凹槽931夾抵住在該主體桿81桿身上而獲得定位,即使得該踏板組80處於收摺狀態,且令收摺後的輪椅體積縮至更小、更不佔空間,此外,因該踏板組80是收置在座墊30上方,其隱密式的收摺方式,讓收摺後的輪椅更紮實感,搬運上會更就手且便利。Therefore, after the folding frame 10 of the wheelchair has been folded by the folding unit 20 and the movable joint 15, respectively, as shown in FIGS. 4 and 5, the folding manner of each of the pedal sets 80 is directly to the main body rod. After the 81 is pulled away from the circular arc groove 923 of the first clamping member 92, the pedal group 80 is directed to Upward pivoting, at this time, the pedal group 80 is rotated and received above the seat cushion 30, and is positioned by the circular groove 931 of the second clamping member 93 against the rod of the body rod 81. That is, the pedal group 80 is in a folded state, and the wheelchair volume after the folding is reduced to a smaller size, and does not occupy a space. Further, since the pedal group 80 is housed above the seat cushion 30, the hidden type is The folding method makes the wheelchair after the folding more solid, and it will be more convenient and convenient to carry.

該踏板組80再次回復成使用狀態時,只需將踏板組80自該座墊30上方向外旋轉拉出,並且將踏板組80的主體桿81再次擠入該第一夾持件92的圓弧槽923而被兩爪形側壁922所夾固,即可讓踏板82回復至使用位置,以供使用者腳部踩踏。When the pedal set 80 is returned to the use state again, only the pedal set 80 is rotated outwardly from above the seat cushion 30, and the body rod 81 of the pedal set 80 is again squeezed into the circle of the first clamp 92. The arc groove 923 is sandwiched by the two claw-shaped side walls 922, so that the pedal 82 can be returned to the use position for the user's foot to step on.
