A rotating plate 24 driven to rotate synchronously, and a control group 25 assembled on the rotating plate unit 20 and the chair frame unit 11. It should be noted that when the rotating plate 24 rotates, the rotating ring piece 22 can also be driven to rotate synchronously.

每一旋板單元20的該固定盤21位於對應的該側架111的外側與對應的該第一轉輪122之間，並形成有一貫穿左右二側且供該第一轉軸121可轉動地穿設的穿孔211，及一徑向往上延伸至外周面的插銷孔212。每一旋板單元20的該旋轉環片22的徑向剖面概成「U」字型，並形成有弧向彼此間隔的一第一固定貫孔221與一第二固定貫孔222。每一旋板單元20的該旋轉板24呈彎弧形的長條板狀，並利用該等連接條23固定地連接於該旋轉環片22的外周面，且能在一位於對應的該第一轉輪122上方的擋泥位置及一貼附於對應的該第一轉輪122底側並撐抵於一地面上的搖擺位置間轉換。該控制組25包括一位於該插銷孔212遠離該固定盤21的外周面的一側的彈性件251、一疊置於該彈性件251上的插銷252、一組裝於對應的該側架111的該握把119的控制把手253，及一連接於該彈性件251鄰近該插銷252的一端並穿出該固定盤21且與該控制把手253連接的連接件254。在本實施例中，該彈性件251是一壓縮彈簧，該連接件254選自於一鐵絲及一不鏽鋼絲。The fixed disk 21 of each rotary plate unit 20 is located between the outer side of the corresponding side frame 111 and the corresponding first rotating wheel 122, and is formed with a penetrating through the left and right sides and for the first rotating shaft 121 to rotatably pass through. A through hole 211 is provided, and a pin hole 212 extending radially upward to the outer peripheral surface. The radial cross section of the rotating ring piece 22 of each rotating plate unit 20 is roughly "U"-shaped, and is formed with a first fixing through hole 221 and a second fixing through hole 222 spaced from each other in an arc direction. The rotating plate 24 of each rotating plate unit 20 is in the shape of a curved long strip, and is fixedly connected to the outer peripheral surface of the rotating ring piece 22 by the connecting strips 23, and can be positioned at the corresponding first The mud guard position above a runner 122 and a swing position attached to the bottom side of the corresponding first runner 122 and supported on the ground are switched. The control group 25 includes an elastic member 251 located on the side of the bolt hole 212 away from the outer peripheral surface of the fixed disk 21, a bolt 252 stacked on the elastic member 251, and a bolt 252 assembled to the corresponding side frame 111 The control handle 253 of the handle 119 and a connecting piece 254 connected to an end of the elastic member 251 adjacent to the plug pin 252 passing through the fixing plate 21 and connected to the control handle 253. In this embodiment, the elastic member 251 is a compression spring, and the connecting member 254 is selected from an iron wire and a stainless steel wire.

該立柱機構3組設於該椅架單元11的該連接桿112(圖1)底側，用以相對該座椅機構1的該椅架單元11，而能在一撐抵於一地面而將該座椅機構1的該第一轉輪單元12的該等第一轉輪122抬離該地面的佇立狀態，及一與該地面間隔而供該第一轉輪單元12的該等第一轉輪122接觸該地面的活動狀態間轉動。The upright mechanism 3 is assembled on the bottom side of the connecting rod 112 (FIG. 1) of the chair frame unit 11 to be opposed to the chair frame unit 11 of the seat mechanism 1, and can be supported against a ground. The standing state of the first runners 122 of the first runner unit 12 of the seat mechanism 1 lifted off the ground, and a spaced apart from the ground for the first runners of the first runner unit 12 The wheel 122 rotates while contacting the ground.

在該等旋板機構2的該等旋轉板24位在該擋泥位置時，每一控制組25的該連接件254不受該控制把手253拉動，故該彈性件251維持不受力之長度最長的狀態，並撐抵該插銷252至突出於該固定盤21的插銷孔212且貫穿該旋轉環片22的該第一固定貫孔221，固定該旋轉環片22不轉動，該旋轉板24也不被該旋轉環片22帶動而轉動。此時，若該立柱機構3位於該活動狀態時，該輪椅裝置能透過該第一轉輪單元12的該等第一轉輪122與該第二轉輪單元13的該等第二轉輪132在該地面轉動而移動；除此之外，該等旋轉板24能阻擋該等第一轉輪122沾染到泥巴或有積水的地面時，往上噴濺的髒汙或汙水滴。再者，在該輪椅裝置行經上坡或下坡時，還能利用該第二輪組13的該等馬達133縮短或伸長該等伸縮桿131，供該坐板113維持在平穩的狀態，避免該坐板113往後傾或往前傾，及使用者隨著該坐板113的傾斜而重心不穩，甚至跌出該輪椅裝置的意外。因此，利用該第二輪組13的設計，能提升使用者乘坐在該輪椅裝置的安全性。When the rotating plates 24 of the rotating plate mechanisms 2 are in the mud guard position, the connecting member 254 of each control group 25 is not pulled by the control handle 253, so the elastic member 251 maintains an unstressed length The longest state, and supports the plug pin 252 to protrude from the pin hole 212 of the fixed disk 21 and penetrates the first fixed through hole 221 of the rotating ring piece 22 to fix the rotating ring piece 22 from rotating, and the rotating plate 24 It is not driven by the rotating ring piece 22 to rotate. At this time, if the column mechanism 3 is in the active state, the wheelchair device can pass through the first wheels 122 of the first wheel unit 12 and the second wheels 132 of the second wheel unit 13 Rotating and moving on the ground; in addition, the rotating plates 24 can block the dirt or sewage droplets splashing upward when the first runners 122 are contaminated with mud or water on the ground. Furthermore, when the wheelchair device travels uphill or downhill, the motors 133 of the second wheel set 13 can also be used to shorten or extend the telescopic rods 131, so that the seat plate 113 can be maintained in a stable state. The seat board 113 is tilted backward or forward, and the user's center of gravity becomes unstable with the tilt of the seat board 113, and even falls out of the wheelchair device. Therefore, the design of the second wheel set 13 can improve the safety of the user riding in the wheelchair device.

參閱圖5至圖7，當該等旋板單元20的該等旋轉板24欲自該擋泥位置轉動到該搖擺位置時，需先將該立柱機構3自該活動狀態轉動到該佇立狀態，使該等第一轉輪122與該地面間隔；之後，持續按壓每一控制組25的該控制把手253以拉緊(如圖5的箭頭所示)該連接件254，既而壓縮該彈性件251的長度，此時，該插銷252連帶地往下移動而不突出於該插銷孔212，該旋轉環片22不受該插銷252的固定而可轉動。5 to 7, when the rotating plates 24 of the rotating plate units 20 want to rotate from the mud guard position to the swing position, the column mechanism 3 needs to be rotated from the active state to the standing state. The first runners 122 are spaced from the ground; then, the control handle 253 of each control group 25 is continuously pressed to tighten (as shown by the arrow in FIG. 5) the connecting member 254, thereby compressing the elastic member 251 At this time, the plug pin 252 moves downward without protruding from the plug hole 212, and the rotating ring piece 22 is not fixed by the plug pin 252 but can rotate.

然後，轉動該旋轉板24，使得該旋轉板24帶動該旋轉環片22轉動，直到該旋轉環片22的該第二固定貫孔222的位置對應位於該插銷252上方；而後，再放鬆每一控制組25的該控制把手253以放鬆該連接件254被拉緊的程度，該彈性件251不再被該連接件254連動壓縮而回復原長度，使該插銷252受回復原長的該彈性件251頂抵而突出於該插銷孔212，且穿設於該等第二固定貫孔222，而將該旋轉板24定位。Then, the rotating plate 24 is rotated so that the rotating plate 24 drives the rotating ring piece 22 to rotate until the position of the second fixing through hole 222 of the rotating ring piece 22 corresponds to the position above the bolt 252; The control handle 253 of the control group 25 relaxes the tension of the connecting member 254, the elastic member 251 is no longer compressed by the connecting member 254 and returns to its original length, so that the bolt 252 is restored to the original length of the elastic member 251 presses against and protrudes from the pin hole 212 and penetrates the second fixing through holes 222 to position the rotating plate 24.

參閱圖8，最後，再將該立柱機構3自該佇立狀態轉動至該活動狀動，使該等旋轉板24撐抵於該地面而位於該搖擺位置，則該輪椅裝置能作為一搖椅使用，供乘坐於其上的使用者的身體能被帶動往後傾斜，而位於不同於必須挺直身驅的斜靠背姿勢。此外，還能利用將該等第二轉輪單元13的馬達133，縮短該等伸縮桿131的長度，避免該輪椅裝置在搖擺時，該等第二轉輪132碰撞地面。Referring to FIG. 8, finally, the column mechanism 3 is rotated from the standing state to the movable state, so that the rotating plates 24 are supported against the ground and located in the swing position, and the wheelchair device can be used as a rocking chair. The body of the user who sits on it can be driven to lean back, and is in a slanting back posture that is different from that of having to stand upright. In addition, the motor 133 of the second wheel unit 13 can be used to shorten the length of the telescopic rods 131 to prevent the second wheels 132 from colliding with the ground when the wheelchair device is swinging.

綜上所述，本發明輪椅裝置，利用該等旋板單元20的該等旋轉板24的設計，而能在該活動位置與該搖擺位置間轉動。在該活動位置時，該等旋轉板24能阻擋該地面的髒汙與汙水往上噴濺；在該搖擺位置時，該等旋轉板24能撐抵於該地面而將該裝置整體作為該搖椅使用，供使用者的身體能往後傾斜，降低身體長時間挺直後的腰椎不適感，故確實能達成本發明之目的。In summary, the wheelchair device of the present invention utilizes the design of the rotating plates 24 of the rotating plate units 20 to rotate between the movable position and the swing position. When in the active position, the rotating plates 24 can block the dirt and sewage on the ground from splashing upward; when in the swing position, the rotating plates 24 can support the ground and the device as a whole The rocking chair is used for the user's body to tilt backwards, reducing the discomfort of the lumbar spine after the body is straight for a long time, so it can achieve the purpose of the invention.

惟以上所述者，僅為本發明之實施例而已，當不能以此限定本發明實施之範圍，凡是依本發明申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾，皆仍屬本發明專利涵蓋之範圍內。However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited by this, all simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification still belong to This invention patent covers the scope.
