Description
本發明係有關於一種病床輔助輪裝置，尤其是指一種輔助病床轉向、迴轉的輪組結構，藉以於病床下設有雙輔助輪，使其病床於轉向、迴轉動作時具有更穩固不搖晃的功效為首先發明應用者。The invention relates to a hospital bed auxiliary wheel device, in particular to a wheel set structure for assisting the turning and turning of a hospital bed, whereby a double auxiliary wheel is arranged under the bed, so that the bed is more stable and not shaken when being turned and rotated. The effect is to first invent the application.
按，於醫院中，一些臥床之重症患者，於往返各診間、檢驗室或病床間時，亦需由醫護人員推動病床將患者推送至各目的地。According to the hospital, some patients with severe beds in bed, when going to and from the clinics, examination rooms or beds, also need to be pushed by the medical staff to push the patients to the destinations.
由於醫院急診或住院人數多時，就會導致病床床位的不足，若增加床位數勢必會造成空間的壓縮，但大部分的醫院為了節省而充分的利用空間，可能一個不算大的空間裡，擺著3~6張病床，病患、家屬共同擠在1、2坪大的限定範圍裡而擁擠不堪，且病房室內外通道、走廊、坡道、避難出入口、室內外出入口、攝影檢查室的進出與迴轉空間、升降梯、廁所盥洗室......等等，也可能會過於狹小，進而造成病床推行移動時的困難，因病床長度關係，當欲進行轉向、迴轉時，其皆需有較大之轉向、迴轉半徑，造成其在操作使用上之極大不便，尤其在狹小空間中，更有可能導致無法轉向、迴轉之情況發生，致令其在整體結構設計上仍存有改進之空間。Because the number of hospital emergency or hospitalization is large, it will lead to the shortage of beds. If the number of beds is increased, it will inevitably cause space compression. However, most hospitals make full use of space for saving, which may not be a large space. With 3 to 6 beds, the patients and their families are crowded together in a limited area of 1, 2 pings, and they are crowded with indoor and outdoor passages, corridors, ramps, evacuation entrances, indoor and outdoor entrances, and photographic examination rooms. In and out and swing space, lifts, toilets, etc., etc., may also be too narrow, which may cause difficulties in moving the bed. Due to the length of the bed, when turning and turning, A large steering and radius of gyration are required, which causes great inconvenience in operation and use, especially in a small space, which is more likely to cause the situation that the steering cannot be turned and the rotation is caused, so that the overall structural design still has improvement. Space.
因此，為了讓病床在有限的空間裡移動時，能夠更加靈活，讓使用者更加容易操作，如公告第M400852號「病床輔助輪機構」的專利，即在病床底部中央位置，裝設有一輔助輪機構，其主要包括有一輔助輪，可被操作下降著地，以使病床形成五輪著地狀態，或者被操作上昇離地，使病床轉變成四輪著地狀態，若當病床被操作成五輪著地狀態時，即適合直向行進及在狹小空間內作迴轉，而當病床被操作成四輪著地狀態時，則適合轉彎的動作。及第公告第M445973號一種病床原地迴轉的輔助輪裝置，是一病床床架的底部中間裝設一輔助輪裝置，並透過一連動桿同步帶動控制前、後床輪與輔助輪裝置的直行或迴旋，而該輔助輪裝置主要包括：一旋轉座單元，是包括一轉盤部下方固設一支座部，並令轉盤部上端軸設於床架上，且令該轉盤部可受到一直行定位單元的定位後而無法轉動，同時又令該支座部下端裝設一可擺動的輔助輪單元；一輔助輪單元，是包括一軸設於上述支座部上、且下端軸設有輪子的輪座，並令輪座與支座部的軸設處裝設一可令輪子彈性著地的緩衝單元。Therefore, in order to allow the bed to move in a limited space, it can be more flexible and easier for the user to operate. For example, the patent of the "bed assisted wheel mechanism" No. M400852 is issued, that is, an auxiliary wheel is installed at the center of the bottom of the bed. The mechanism mainly comprises an auxiliary wheel, which can be operated to descend to the ground, so that the bed forms a five-wheel landing state, or is operated to rise off the ground, so that the bed is turned into a four-wheel landing state, and if the bed is operated into five wheels In the ground state, it is suitable for straight travel and rotation in a narrow space, and when the hospital bed is operated in a four-wheel landing state, it is suitable for the turning action. And the auxiliary wheel device of the in-situ rotation of a hospital bed No. M445973 is an auxiliary wheel device installed in the middle of the bottom of the bed frame, and is controlled by a linkage rod to directly drive the front and rear bed wheels and the auxiliary wheel device to go straight. Or the swinging wheel, and the auxiliary wheel device mainly comprises: a rotating base unit, which comprises a seat portion fixed under a turntable portion, and the upper end shaft of the turntable portion is arranged on the bed frame, and the turntable portion can be subjected to the line After positioning, the positioning unit cannot be rotated, and at the same time, the lower end of the support portion is provided with a swingable auxiliary wheel unit; an auxiliary wheel unit includes a shaft disposed on the support portion and the lower end shaft is provided with a wheel. The wheel base and the shaft seat of the wheel base and the seat portion are provided with a buffer unit for elastically engaging the wheel.
而上述結構大致上都是在病床架底部中間裝設單一輔助輪，而當輔助輪著地之後呈三點接觸，但未著地的二輪也是具有重量且病人也在病床上，會導至病床移動時，有搖晃不穩的現象，而且單輪不容易控制行進方向，也容易因地面些微隆起而致使病床的突然不定轉向而發生危險。The above structure is generally provided with a single auxiliary wheel in the middle of the bottom of the bed frame, and three points of contact after the auxiliary wheel touches the ground, but the second wheel that does not touch the ground also has weight and the patient is also in the hospital bed, leading to the hospital bed. When moving, there is a phenomenon of shaking and instability, and it is not easy to control the traveling direction in a single wheel, and it is also easy to cause a sudden indefinite turn of the bed due to slight bulging of the ground.
緣是，發明人有鑑於此，秉持多年該相關行業之豐富設計開發及實際製作經驗，針對現有之結構再予以研究改良，因而發明出一種病床輔助輪裝置，以期達到更佳實用價值性之目的者。In view of this, the inventor has invented a research and improvement of the existing structure based on the rich experience in design and development and actual production of the relevant industry for many years, thus inventing a hospital bed auxiliary wheel device for the purpose of achieving better practical value. By.
