The connection shown in FIG. 6 or FIG. 7 is adopted on both the left and right sides for connection and fixation of the lower knee leg 10 rotatably provided on the lower knee frame 6.
また、台座枠３、背もたれ枠４、頭部枠５、膝下枠及び足載せ枠７は、相互に回転自在に接続されている。これは例えば、図８及び図９に示す構造となる。台座枠３と背もたれ枠４の突合せ箇所に蝶番１７が設けられている。この蝶番１７は、環体１７ａを二つ並べた、断面横８の字型で、一方の環体１７ａに台座枠３を回転可能に挿入し、他方の環体１７ａに背もたれ枠４を回転可能に挿入している。また、これらの蝶番１７を設ける台座枠３及び背もたれ枠４の外周に環状凹部３ａ及び環状凹部４ａを夫々設け、これらの環状凹部３ａ及び環状凹部４ａに前記各環体１７ａを被せている。これにより、前記蝶番１７は横方向にずれない。他の枠体相互の接続も前記図８、図９と同様である。 The pedestal frame 3, the backrest frame 4, the head frame 5, the lower knee frame, and the footrest frame 7 are connected to each other so as to be freely rotatable. This is, for example, the structure shown in FIGS. A hinge 17 is provided at a place where the pedestal frame 3 and the backrest frame 4 meet each other. This hinge 17 has a shape of a cross section of 8 in which two ring bodies 17a are arranged side by side. The base frame 3 is rotatably inserted into one ring body 17a, and the back frame 4 can be rotated to the other ring body 17a. Is inserted. Further, an annular recess 3a and an annular recess 4a are provided on the outer periphery of the base frame 3 and the backrest frame 4 on which the hinges 17 are provided, respectively, and the annular bodies 17a are covered with the annular recess 3a and the annular recess 4a. As a result, the hinge 17 does not shift laterally. The connection between the other frames is the same as in FIGS.
この様にして、内枠Ｂの台座枠３を外枠Ａに固定し、各背もたれ脚８、頭部脚９及び膝下脚１０を固定すると、図２に示すように、台座枠３、背もたれ枠４、頭部枠５、膝下枠６及び足載せ枠７が同じ高さで水平に並び、ベッドが完成する。 In this way, when the pedestal frame 3 of the inner frame B is fixed to the outer frame A, and each back leg 8, head leg 9 and lower knee leg 10 are fixed, the pedestal frame 3, back frame as shown in FIG. 4, the head frame 5, the knee lower frame 6 and the footrest frame 7 are arranged horizontally at the same height, and the bed is completed.
この状態から、車椅子にするには、まず、図１０に示すように、膝下枠６に回転自在に接続した膝下脚１０を前記外枠Ａの内側に入れて当該膝下枠６を台座枠３に対して略直角に折り曲げ、また、足載せ枠７を、膝下枠６の前方に略直角に折り曲げ、図１１に示すように固定する。この固定は、膝下枠６の側面に一端を軸支した回転板１８の自由端の係止切欠き１８ａを足載せ枠７の側面に螺着したボルト１９に引っ掛け、当該ボルト１９を締め付けることにより固定する。これは膝下枠６及び足載せ枠７の左右両側について行う。 In order to make a wheelchair from this state, first, as shown in FIG. 10, the lower knee leg 10 rotatably connected to the lower knee frame 6 is put inside the outer frame A, and the lower knee frame 6 is attached to the base frame 3. The footrest frame 7 is bent at a substantially right angle, and the footrest frame 7 is bent at a substantially right angle in front of the lower knee frame 6 and fixed as shown in FIG. This fixing is achieved by hooking a locking notch 18a at the free end of the rotating plate 18 pivotally supported on one side to the side surface of the lower knee frame 6 to a bolt 19 screwed on the side surface of the footrest frame 7 and tightening the bolt 19. Fix it. This is performed on both the left and right sides of the lower knee frame 6 and the footrest frame 7.
また、図１２に示すように、台座枠３の後方の背もたれ枠４及び頭部枠５を山形に重ねて立ち上げる。その際、前記各回転板１３及び１５の係止を解き、背もたれ脚８及び頭部脚９を回転フリーにしておく。そして、頭部脚９を、図１２に示すように回転させ、図１３に示すように、頭部脚９の先端を前記台座枠３の前部両側に設けた突出棒１２に係止する。 Moreover, as shown in FIG. 12, the backrest frame 4 and the head frame 5 behind the pedestal frame 3 are piled up in a mountain shape. At that time, the locking of the rotary plates 13 and 15 is released, and the backrest leg 8 and the head leg 9 are made free to rotate. Then, the head leg 9 is rotated as shown in FIG. 12, and as shown in FIG. 13, the tip of the head leg 9 is locked to the protruding bars 12 provided on both sides of the front part of the pedestal frame 3.
この頭部脚９の突出棒１２への係止は、図１４に示すように、突出棒１２の上端に、二つ割の環状の係止具２０を設け、当該係止具２０内に頭部脚９の水平片を嵌め入れ、係止するものである。この係止具２０は、半環状の基部２０ａを前記突出棒１２に固定し、この基部２０ａに蝶番で接続された半環状の蓋部２０ｂを開閉自在とし、前記頭部脚９の水平片を基部２０ａの湾曲凹部に入れ、この上から蓋部２０ｂを被せ、当該蓋部２０ｂを基部２０ａに係止するものである。 As shown in FIG. 14, the head leg 9 is locked to the protruding rod 12 by providing a split annular locking member 20 at the upper end of the protruding rod 12. The horizontal piece of the leg 9 is fitted and locked. This locking tool 20 fixes a semi-annular base portion 20a to the projecting rod 12, allows a semi-annular lid portion 20b connected to the base portion 20a with a hinge to be opened and closed, and allows the horizontal piece of the head leg 9 to be opened and closed. The base 20a is placed in a curved recess, covered with a lid 20b, and the lid 20b is locked to the base 20a.
これにより、患者は前記台座枠３にお尻を載せて当該車椅子に座り、上述のように前記頭部脚９を回して前記突出棒１２の上端に当該頭部脚９の先端を係止すると、この頭部脚９の水平片と台座枠３の前端との間に空間が出来、患者この間から前方に脚を出すことが出来る。また、背もたれ枠４は頭部枠５と共に前記頭部脚９に支持され、患者は背もたれ枠４に寄りかかっても頭部脚９が突出棒１２に係止されているため、背もたれ枠４は動かない。 As a result, the patient sits on the wheelchair with his buttocks on the pedestal frame 3, and turns the head leg 9 as described above to lock the tip of the head leg 9 to the upper end of the protruding rod 12. A space is formed between the horizontal piece of the head leg 9 and the front end of the pedestal frame 3, and the patient can put out the leg forward from this space. Further, the back frame 4 is supported by the head leg 9 together with the head frame 5, and even if the patient leans against the back frame 4, the head leg 9 is locked to the protruding rod 12, so the back frame 4 is It does n’t move.
また、当該車椅子に乗った患者は、前記頭部脚９が患者の左右の脇にあるため、手すりや支えとなり、さらに、前記のように患者の脚が頭部脚９の水平片と台座枠３の前部の隙間に入っていため、車椅子が多少ゆれても車椅子から落ちる恐れが無い。また、上記実施例１に代えて、頭部脚９を台座枠３の前部に直接係止する構成でも良い。この場合、上述のように、頭部脚９と台座枠３の間の間隙は無いが、頭部脚９が患者の左右の脇にあり手すりや支えとなる。 Further, since the head leg 9 is on the left and right sides of the patient, the patient in the wheelchair serves as a handrail and a support. Further, as described above, the patient's leg is supported by the horizontal piece of the head leg 9 and the pedestal frame. Since it is in the gap at the front of 3, there is no risk of falling out of the wheelchair even if the wheelchair is slightly shaken. Moreover, it may replace with the said Example 1 and the structure which latches the head leg 9 directly to the front part of the base frame 3 may be sufficient. In this case, as described above, there is no gap between the head leg 9 and the base frame 3, but the head leg 9 is on the left and right sides of the patient and serves as a handrail and support.
また、図１５に示すように、前記台座枠３の内側には、内周に水平に突出する突出縁２１ａを有する枠体２１を固定し、当該枠体２１に板体２２を着脱自在に嵌めている。この板体２２には取っ手２２ａを設けて、前記枠体２１から取り出しやすくしている。また、前記板体２２に代えて、中央部に透孔２３ａを有する板体２３を着脱自在に前記枠体２１に嵌めることもできる。この板体２３にも取っ手２３ｂを設けて、前記枠体２１から取り出しやすくしている。 Further, as shown in FIG. 15, a frame body 21 having a protruding edge 21 a that protrudes horizontally on the inner periphery is fixed to the inside of the pedestal frame 3, and a plate body 22 is detachably fitted to the frame body 21. ing. The plate body 22 is provided with a handle 22a so that it can be easily taken out from the frame body 21. Further, instead of the plate 22, a plate 23 having a through hole 23 a in the center can be detachably fitted to the frame 21. The plate body 23 is also provided with a handle 23b to facilitate removal from the frame body 21.
また、この発明の車椅子は、外枠Ａは後部下部に横棒のない略直方体形状であるため、図１６に示すように、洋式便器Ｃを外枠Ａの後から外枠Ａ内に入れることが出来る。その場合、予め、前記板体２３を台座枠３の枠体２１に嵌めておく。これにより、当該車椅子に患者を乗せたまま、洋式便器Cの上方に前記中央部に透孔２３ａを有する板体２３を持っていくことができる。これにより患者が車椅子に乗ったままトイレで用を足すことが出来、いちいちトイレで便器に乗り移ることが不要となる。 Further, in the wheelchair according to the present invention, the outer frame A has a substantially rectangular parallelepiped shape without a horizontal bar at the lower part of the rear portion, so that the western-style toilet C is inserted into the outer frame A from the rear of the outer frame A as shown in FIG. I can do it. In that case, the plate body 23 is fitted in the frame body 21 of the base frame 3 in advance. Thereby, the plate body 23 which has the through-hole 23a in the said center part above the western-style toilet C can be taken with the patient on the said wheelchair. As a result, the patient can use the toilet while riding on a wheelchair, and it becomes unnecessary to transfer to the toilet in the toilet.
また、この発明の車椅子は、図１７に示すように、外枠Ａの後ろから内側に気体又は液体の挿入により伸縮して高さが変化する伸縮部材Ｄを挿入し、この伸縮部材Ｄの高さを上げる。これにより台座枠３が上がり、前記外枠Ａの被係止突片１の孔１ａから内枠Ｂの台座枠３の係止突片１１の突棒１１ａが抜け、当該被係止突片１と係止突片１１の係合が解かれる。そこで、介護者等が背もたれ枠４等を前方に少し押し、この状態で前記伸縮部材Ｄの気体又は液体を排出させ、当該伸縮部材Ｄの高さを低くする。これにより、前記内枠Ｂの台座枠３、背もたれ枠４、頭部枠５が外枠Ａ内に収納され、患者が座ったまま当該車椅子の高さを低くすることが出来る。また、前記伸縮部材Ｄを使って元の状態に容易に戻すことが出来る。 Moreover, as shown in FIG. 17, the wheelchair of this invention inserts the expansion-contraction member D which expands and contracts by insertion of gas or liquid from the back to the inside of the outer frame A, and changes the height of this expansion-contraction member D. Raise the height. As a result, the base frame 3 is raised, and the protruding rod 11a of the locking protrusion 11 of the base frame 3 of the inner frame B is pulled out from the hole 1a of the locking protrusion 1 of the outer frame A. And the engagement of the locking protrusion 11 is released. Therefore, a caregiver or the like pushes the back frame 4 or the like slightly forward, and in this state, the gas or liquid of the elastic member D is discharged, and the height of the elastic member D is lowered. Thereby, the base frame 3, the backrest frame 4, and the head frame 5 of the inner frame B are accommodated in the outer frame A, and the height of the wheelchair can be lowered while the patient is sitting. Moreover, it can return to an original state easily using the said expansion-contraction member D. FIG.
従って、図１８に示すように、車椅子ごと浴槽Ｅに入れ、前記伸縮部材Ｄを使って上述の様に、車椅子の台座枠３等を低くすることが出来る。それ故、患者が車椅子に座ったまま浴槽Ｅに入り、湯につかることができる。 Accordingly, as shown in FIG. 18, the wheelchair can be placed in the bathtub E and the pedestal frame 3 of the wheelchair can be lowered using the telescopic member D as described above. Therefore, the patient can enter the bathtub E while sitting in a wheelchair and can take a bath.
また、上記実施例１では、背もたれ枠４と背もたれ脚８を図６に示すように、相互に直角に固定したが、図１９に示すように、背もたれ枠４に設けた舌片３０と背もたれ脚８に設けた舌片３１とを重ね、これらの舌片３０及び３１に予め設けた孔に、馬蹄形係止片３２を入れて相互に直角に固定しても良い。これは頭部枠５と頭部脚９、膝下枠６と膝下脚１０及び膝下枠６と足載せ枠７との固定についても同様に図２３の構成が採れる。また、これらの固定構造に限るものではない。 In the first embodiment, the back frame 4 and the back leg 8 are fixed at right angles to each other as shown in FIG. 6, but the tongue piece 30 provided on the back frame 4 and the back leg as shown in FIG. 8 may be overlapped with each other, and horseshoe-shaped locking pieces 32 may be inserted into holes provided in the tongue pieces 30 and 31 in advance and fixed at right angles to each other. The configuration shown in FIG. 23 is similarly applied to fixing the head frame 5 and the head leg 9, the lower knee frame 6 and the lower knee leg 10, and the lower knee frame 6 and the footrest frame 7. Moreover, it is not restricted to these fixed structures.
また、図２０は、前記台座枠３の四隅にアングル材からなる垂直ガイド３３を垂直に設け、前部の両側の垂直ガイド３３は、当該垂直ガイド３３の中ほどを、前記台座枠３の角部にその凹部を当てて固定し、後部の両側の垂直ガイド３３は下端の凹部を、前記台座枠３の角部に当てて固定したものである。その際、台座枠３と背もたれ枠４又は膝下枠６との間に前記垂直ガイド３３を設けるが、これらの間隙は、図２１及び２２に示す蝶番１７´を用いれば可能である。また、前記外枠Ａの両側前後に、前記垂直ガイド３３を摺動自在に受ける、アングル材からなるレール材３４を夫々垂直に設けているものである。これらのレール材３４のうち、両側の後部のレール材３４の上端は、外枠Ａの上部水平片より低くなっている。また、両側の前後のレール材３４は夫々前記各被係止片１より前方に位置している。 Further, in FIG. 20, vertical guides 33 made of an angle material are provided vertically at the four corners of the pedestal frame 3, and the vertical guides 33 on both sides of the front part are arranged at the corners of the pedestal frame 3 in the middle of the vertical guides 33. The vertical guides 33 on both sides of the rear part are fixed by applying the concave part at the lower end to the corner part of the pedestal frame 3. At this time, the vertical guide 33 is provided between the pedestal frame 3 and the backrest frame 4 or the lower knee frame 6. These gaps can be formed by using a hinge 17 'shown in FIGS. In addition, rail members 34 made of angle members, which slidably receive the vertical guides 33, are provided vertically on both sides of the outer frame A, respectively. Among these rail members 34, the upper ends of the rear rail members 34 on both sides are lower than the upper horizontal piece of the outer frame A. Further, the front and rear rail members 34 on both sides are positioned in front of the respective locked pieces 1.
これらの垂直ガイド３３を有する台座枠３の下に前記伸縮部材Ｄを置いて、台座枠３を上昇させて、上述のように、前記外枠Ａとの係合を解き、介護者が当該台座枠３を前方に押すと、両側の前部の垂直ガイド３３が外枠Ａの両側の前部のレール材３４に当り、そこで、前記伸縮部材Ｄで台座枠３を下げると、台座枠３の前部の垂直ガイド３３は外枠Ａの前部のレール材３４に沿って下がり、台座枠３の後部の垂直ガイド３３が、外枠Ａの後部のレール材３４に嵌合し、当該レール材３４に沿って下がる。さらに伸縮部材Ｄを縮ませると、台座枠３は外枠Ａの４箇所のレール材３４に沿って下降し、常に水平を保って下降する。また、前記伸縮部材Ｄを膨らませると、台座枠３の垂直ガイド３３は前記レール材３４に沿って摺動し乍上昇し、台座枠３は常に安定して上下する。 The telescopic member D is placed under the pedestal frame 3 having the vertical guides 33, the pedestal frame 3 is raised, and the engagement with the outer frame A is released as described above. When the frame 3 is pushed forward, the front vertical guides 33 on both sides hit the front rail members 34 on both sides of the outer frame A, and when the pedestal frame 3 is lowered by the elastic members D, the pedestal frame 3 The front vertical guide 33 is lowered along the front rail member 34 of the outer frame A, and the rear vertical guide 33 of the pedestal frame 3 is fitted to the rear rail member 34 of the outer frame A. Go down along 34. When the telescopic member D is further contracted, the pedestal frame 3 descends along the four rail members 34 of the outer frame A, and always descends while maintaining the level. When the telescopic member D is inflated, the vertical guide 33 of the pedestal frame 3 slides along the rail material 34 and rises, and the pedestal frame 3 always moves up and down stably.
また、その際、図２１に示すように、台座枠３の前部に把手３５を設けておけば、介護者がこの把手３５を手で持って上下すれば、台座枠３が前のめりになったりするのを防ぐことができ、台座枠３を、さらに安定して上下させることが出来る。この把手３５は、その両側で台座枠３の前部に回転自在に支持され、必要時に起せばよい。従って、この車椅子をベッドにした場合でも、前記把手３５を倒せば邪魔にならない。また、前記蝶番１７´は、図２２に示すように、環体１７ａと環体１７ａとの間に連結体１７ｂを設けたものである。 In this case, as shown in FIG. 21, if a handle 35 is provided at the front portion of the pedestal frame 3, the pedestal frame 3 can be turned forward if the caregiver holds the handle 35 up and down. And the pedestal frame 3 can be moved up and down more stably. The handle 35 is rotatably supported by the front part of the pedestal frame 3 on both sides thereof, and may be raised when necessary. Therefore, even when this wheelchair is used as a bed, it does not get in the way if the handle 35 is lowered. Further, as shown in FIG. 22, the hinge 17 'is provided with a connecting body 17b between the ring body 17a and the ring body 17a.
また、前記伸縮部材Ｄを用いないで、当該車椅子の台座枠３の高さを低くすることも出来る。
先ず、外枠Ａの左右の上部水平片に図２１のアングル材２５を夫々固定する。これらのアングル材２５の間には予め、ゴムネット２６を張っておく。また、図２２に示すように、外枠Ａの両側の前後に、垂直に設けたレバー棒２７の上部に上部ストッパー２８を、また、下部に下部ストッパー２９を夫々略水平に突出させ、前記各レバー棒２７は回転自在に支持されている。そして、前記外枠Ａとの係合を解いた、台座枠３を前記ゴムネット２６の上に載せ、前記前後の各上部ストッパー２８を回して前記ゴムネット２６の下にしておく。これにより図２３に示すように、患者がこの車椅子に乗っても、台座枠３は左右前後の上部ストッパー２８に支持され、患者の荷重に耐えられる。
Moreover, the height of the pedestal frame 3 of the wheelchair can be lowered without using the elastic member D.
First, the angle members 25 of FIG. 21 are fixed to the left and right upper horizontal pieces of the outer frame A, respectively. A rubber net 26 is stretched between these angle members 25 in advance. Further, as shown in FIG. 22, an upper stopper 28 is provided on the upper part of the lever rod 27 provided vertically and a lower stopper 29 is provided on the lower part of the front and rear sides of the outer frame A, respectively. The lever rod 27 is rotatably supported. Then, the pedestal frame 3, which has been disengaged from the outer frame A, is placed on the rubber net 26, and the front and rear upper stoppers 28 are rotated and placed under the rubber net 26. Accordingly, as shown in FIG. 23, even if the patient gets on this wheelchair, the pedestal frame 3 is supported by the left and right upper and lower upper stoppers 28 and can withstand the patient's load.
そして、患者が車椅子に座った状態で浴槽Ｅに入り、湯を入れない状態で、前記各レバー棒２７を軸を中心に回転させ、各上部ストッパー２８を台座枠３の下から外す。これにより患者の体重で前記ゴムネット２６が伸び、台座枠３は沈む。そこで、図２４に示すように、前記各レバー棒２７を回転させて各下部ストッパー２９を台座枠３の上に被せ、当該台座枠３が浮上するのを押さえる。この状態で患者は浴槽につかる事が出来る。そして、入浴後は、下部ストッパー２９を回転さると、浮力で患者の体重は軽くなり、台座枠３は浮き上がり、前記各レバー棒２７を回して前記各上部ストッパー２８を台座枠３の下に入れ、元の車椅子となる。 Then, in a state where the patient is sitting on the wheelchair and enters the bathtub E, and without pouring hot water, the lever bars 27 are rotated around the axis, and the upper stoppers 28 are removed from the bottom of the pedestal frame 3. Thereby, the rubber net 26 is extended by the weight of the patient, and the pedestal frame 3 sinks. Therefore, as shown in FIG. 24, the lever rods 27 are rotated to cover the lower stoppers 29 on the pedestal frame 3, thereby preventing the pedestal frame 3 from floating. In this state, the patient can take a bath. After bathing, when the lower stopper 29 is rotated, the patient's weight is reduced by buoyancy, the pedestal frame 3 is lifted, and the lever stoppers 27 are turned to put the upper stoppers 28 under the pedestal frame 3. Become the original wheelchair.
なお、図２３以下の前記実施例ではアングル材２５を用い、２つのアングル材２５を夫々外枠Ａの左右の上部水平片に固定し、これらのアングル材２５の間にゴムネット２６を張ったが、これらのアングル材２５を用いずに、外枠Ａの左右の上部水平片にゴムネット２６の端部を直接係止して、左右の上部水平片間にゴムネット２６を張り、このゴムネット２６の上に台座枠３を乗せる構成にしてもよい。この場合においても、前記レバー棒２７、上部ストッパー２８及び下部ストッパー２９は同様に設けるため、各部は上述と同様に作用する。 23 and the following examples, angle members 25 are used, and the two angle members 25 are fixed to the left and right upper horizontal pieces of the outer frame A, respectively, and a rubber net 26 is stretched between these angle members 25. However, without using these angle members 25, the ends of the rubber net 26 are directly locked to the left and right upper horizontal pieces of the outer frame A, and the rubber net 26 is stretched between the left and right upper horizontal pieces. You may make it the structure which mounts the base frame 3 on the net | network 26. FIG. Also in this case, since the lever rod 27, the upper stopper 28 and the lower stopper 29 are provided in the same manner, the respective parts act in the same manner as described above.
