Description

本発明は、例えば災害発生時に担架に乗せられた負傷者を安全な場所まで素早く運搬（移動）することが可能な防災用折り畳み式リヤカーに関する。   The present invention relates to a foldable rear car for disaster prevention that can quickly transport (move) an injured person on a stretcher to a safe place when a disaster occurs, for example.

一般的に、災害発生時等に発電機や消火器等の災害用備品を運搬する場合の運搬手段としてリヤカーが使用されている。従来、このリヤカーは、地域の防災倉庫等に各種備品と共に保管されることから、例えば特許文献１に示すように折り畳み可能に構成されている。すなわち、リヤカーは、荷物等が積載される荷台部と、タイヤ車輪が取り付けられた側壁部及び着脱可能な前壁部及び後壁部と、荷台部の前方に取り付けられる牽引ハンドル等を有し、これらが折り畳まれて保管時にはその外形が小さくなるように構成されている。   In general, a rear car is used as a transportation means for transporting disaster equipment such as a generator or a fire extinguisher when a disaster occurs. Conventionally, since this rear car is stored together with various equipments in a local disaster prevention warehouse or the like, for example, as shown in Patent Document 1, it can be folded. That is, the rear car has a loading platform portion on which luggage or the like is loaded, a side wall portion to which tire wheels are attached, a detachable front wall portion and a rear wall portion, a traction handle attached to the front of the loading platform portion, and the like. These are folded and configured so that the outer shape becomes smaller during storage.

そして、操作部２４を押し下げた非作動位置においては、押圧部材２５が後退してその先端部とタイヤ車輪１０との間に所定の間隙が確保されて、タイヤ車輪１０の回転が自由となっている。この状態で、操作部２４の摘み２４ａを掴んで上方（図８の矢印ロ方向）に引き上げることにより、各リンク板２３ａ〜２３ｃが図８の二点鎖線で示すように回動し、押圧部材２５が前方に進出してその先端面がタイヤ車輪１０の外周面に所定圧で当接する。なお、操作部２４は、側壁部材５の外面に固定されたガイド板２４ｂでガイドされて上下動するようになっている。   And in the non-operation position which pushed down the operation part 24, the press member 25 reverse | retreats, a predetermined clearance is ensured between the front-end | tip part and the tire wheel 10, and rotation of the tire wheel 10 becomes free. Yes. In this state, by grasping the knob 24a of the operation unit 24 and pulling it upward (in the direction of the arrow B in FIG. 8), the link plates 23a to 23c rotate as indicated by the two-dot chain lines in FIG. 25 advances forward, and the front end surface thereof contacts the outer peripheral surface of the tire wheel 10 with a predetermined pressure. The operation unit 24 is guided by a guide plate 24b fixed to the outer surface of the side wall member 5, and moves up and down.

これによりタイヤ車輪１０の回転が規制され、リヤカー本体２を所定場所に駐輪できることになる。このとき、押圧部材２５のタイヤ車輪１０への当接位置は、タイヤ車輪１０の軸芯を水平に結ぶ線より下側となるように設定されており、押圧部材２５でタイヤ車輪１０の回転が確実に規制されることになる。なお、図１においては、駐輪機構２１を便宜上カバーで覆うようにしているが、このカバーは必ずしも必要ではなく、省略することも勿論可能である。   Thereby, the rotation of the tire wheel 10 is restricted, and the rear car body 2 can be parked at a predetermined place. At this time, the contact position of the pressing member 25 with the tire wheel 10 is set to be lower than a line connecting the axis of the tire wheel 10 horizontally, and the rotation of the tire wheel 10 by the pressing member 25 is performed. It will surely be regulated. In FIG. 1, the bicycle parking mechanism 21 is covered with a cover for the sake of convenience, but this cover is not always necessary and can of course be omitted.

前記リヤカー本体２には、図３に示すように、両側壁部材５（もしくは荷台部４）の後端部下面両側に傾動防止機構２７がそれぞれ設けられている。この傾動防止機構２７は、図９に示すように、下端に当接板２７ａが固定されたロッド２７ｂと、このロッド２７ｂの上端を回動可能に支持する支持金具２７ｃと、ロッド２７ｂの係止棒と側壁部材５の係止棒との間に配設されたスプリング２７ｄ等を有している。そして、傾動防止機構２７の作動位置である図９の実線位置から、ロッド２７ｂを足や手で矢印イの如く押して回動させることにより、ロッド２７ｂが二点鎖線で示すように側壁部材５の下部に折り畳まれるようになっている。   As shown in FIG. 3, the rear car body 2 is provided with tilt prevention mechanisms 27 on both sides of the lower surface of the rear end portion of the side wall members 5 (or the loading platform 4). As shown in FIG. 9, the tilt prevention mechanism 27 includes a rod 27b having a contact plate 27a fixed to the lower end, a support fitting 27c that rotatably supports the upper end of the rod 27b, and an engagement of the rod 27b. A spring 27d and the like disposed between the bar and the locking bar of the side wall member 5 are provided. Then, from the position of the solid line in FIG. 9, which is the operation position of the tilt prevention mechanism 27, the rod 27 b is pushed and rotated as indicated by an arrow A with a foot or hand, so that the rod 27 b of the side wall member 5 is indicated by a two-dot chain line. It can be folded at the bottom.

なお、前記スプリング２７ｄは、ロッド２７ｂを収納位置に保持すると共に、その付勢力に抗して反矢印イ方向に９０度以上回動されることで、ロッド２７ｂを実線で示す作動位置に保持するようになっている。また、ロッド２７ｂの当接板２７ａ下端の高さ位置は、図３に示す側壁部材５の先端下部にそれぞれ設けられる脚２８の高さより所定寸法高く設定されて、リヤカー本体２が後方側（後壁部材７側）に傾動し当接板２７ａが路面Ｒに接触した際に、リヤカー本体２が路面Ｒに対して例えば略平行となるように設定されている。このロッド２７ｂの長さは、当接板２７ａをロッド２７ｂに対して伸縮可能として調整できるようにしても良い。   The spring 27d holds the rod 27b in the retracted position, and holds the rod 27b in the operating position indicated by a solid line by being rotated 90 degrees or more in the direction of the opposite arrow B against the biasing force. It is like that. Further, the height position of the lower end of the contact plate 27a of the rod 27b is set to be a predetermined dimension higher than the height of the leg 28 provided at the lower end of the side wall member 5 shown in FIG. The rear car body 2 is set so as to be substantially parallel to the road surface R, for example, when the contact plate 27a contacts the road surface R by tilting toward the wall member 7 side. The length of the rod 27b may be adjusted so that the contact plate 27a can be expanded and contracted with respect to the rod 27b.

図１０〜図１３は、前記リヤカー本体２に載置される担架３の一実施形態を示している。この担架３は、図１０及び図１１に示すように、左右一対の支持フレーム３ａと、この支持フレーム３ａ間に配設されたシート３ｂを有している。前記支持フレーム３ａは、例えばアルミパイプで形成された２本のパイプ３１を有し、これらが連結金具３２の二つの軸３２ａで、図１１の二点鎖線で示すように折り畳み可能に連結されると共に、負傷者が乗せられていない初期状態においては、連結金具３２部分が上方に寸法ｈ反った状態となっている。   10 to 13 show an embodiment of the stretcher 3 placed on the rear car body 2. As shown in FIGS. 10 and 11, the stretcher 3 includes a pair of left and right support frames 3a and a seat 3b disposed between the support frames 3a. The support frame 3a has, for example, two pipes 31 formed of aluminum pipes, and these are connected to each other by two shafts 32a of the connection fitting 32 so as to be foldable as shown by a two-dot chain line in FIG. At the same time, in the initial state in which no injured person is placed, the connecting metal fitting 32 is warped upward by the dimension h.

また、両支持フレーム３ａの各パイプ３１の両先端にはゴム製のグリップ３３が嵌挿されると共に、両支持フレーム３ａの長手方向の両端所定位置には、所定高さの脚部３４がそれぞれ（合計４個）固定されている。この脚部３４は、担架３に乗せた負傷者の身体を拘束する図示ないベルトが取り付けられるベルト取付孔３４ａを有すると共に、一対の支持フレーム３ａを連結する板状の連結フレーム３５の端部がそれぞれ回動可能に連結されている。なお、前後一対の脚部３４の間隔は、前記リヤカー本体２の前壁部材６と後壁部材７の間隔と同一か大きめとなるように設定されている。   In addition, rubber grips 33 are inserted into both ends of the pipes 31 of both support frames 3a, and legs 34 having a predetermined height are respectively provided at predetermined positions on both ends of the support frames 3a in the longitudinal direction ( A total of 4) is fixed. The leg 34 has a belt attachment hole 34a to which a belt (not shown) for restraining the body of an injured person placed on the stretcher 3 is attached, and an end of a plate-like connection frame 35 for connecting the pair of support frames 3a. Each is pivotably connected. The distance between the pair of front and rear legs 34 is set to be equal to or larger than the distance between the front wall member 6 and the rear wall member 7 of the rear car body 2.

そして、前記連結フレーム３５は、図１２に示すように、基端側が前記脚部３４に連結され先端側が基端部より低く形成された左右一対の連結板３５ａと、この両連結板３５ａの先端を回動可能に連結する連結支持板３５ｂを有している。この両連結板３５ａと連結支持板３５ｂとにより、一対の連結板３５ａが連結されて両支持フレーム３ａが所定幅に設定されると共に、連結フレーム３５の幅方向中央に下方に窪んだ凹部３６が形成され、この凹部３６によりシート３ｂ上に乗せられた負傷者の身体が、シート３ｂを介して連結板３５ａに接触しないようになっている。   As shown in FIG. 12, the connecting frame 35 includes a pair of left and right connecting plates 35a whose proximal end is connected to the leg portion 34 and whose distal end is formed lower than the proximal end, and the distal ends of the connecting plates 35a. Is connected to the support plate 35b. The connecting plates 35a and the connecting support plates 35b connect the pair of connecting plates 35a to set the support frames 3a to a predetermined width, and a recess 36 that is recessed downward in the center of the connecting frame 35 in the width direction. The body of the injured person formed and placed on the sheet 3b by the recess 36 does not come into contact with the connecting plate 35a via the sheet 3b.

また、前記連結支持板３５ｂは、図１３に示すように、支持フレーム３ａの長手方向の内側に開口した断面コ字状に形成され、両連結板３５ａの先端がピンにより回動可能に連結されている。そして、連結支持板３５ｂを矢印ニの如く押すことにより、両連結板３５ａが矢印ホの如く回動、すなわち連結板３５ａが折り畳まれた状態となる。なお、前記シート３ｂは、例えば防水加工されたポリエステル、布等で形成され、その幅方向両端に設けたフレーム支持部に、前記支持フレーム３ａがそれぞれ挿入もしくは嵌装されるようになっている。   Further, as shown in FIG. 13, the connection support plate 35b is formed in a U-shaped cross-section opening inside the longitudinal direction of the support frame 3a, and the ends of both connection plates 35a are connected to each other by pins. ing. Then, by pushing the connection support plate 35b as indicated by an arrow D, both connection plates 35a are rotated as indicated by an arrow H, that is, the connection plate 35a is folded. The sheet 3b is formed of, for example, waterproof polyester, cloth, or the like, and the support frames 3a are respectively inserted or fitted into frame support portions provided at both ends in the width direction.

次に、本発明に係わるリヤカー１の使用方法の一例について説明する。例えば災害が発生して負傷者を安全な場所まで避難させようとする場合、先ず、地区の防災倉庫等に保管されているリヤカー本体２と担架３を取り出し、折り畳まれた状態のリヤカー本体２を組み立てて、図１に示す状態にする。このリヤカー本体２の組み立ては、前述した折り畳みと逆の操作で行うことができ、その際、リヤカー本体２の前記駐輪機構２１を作動させてタイヤ車輪１０の回転を規制すると共に、前記傾動防止機構２７を作動位置に設定する。   Next, an example of how to use the rear car 1 according to the present invention will be described. For example, when a disaster occurs and an injured person is to be evacuated to a safe place, first, the rear car body 2 and the stretcher 3 stored in the disaster prevention warehouse of the district are taken out, and the rear car body 2 in a folded state is removed. Assemble to the state shown in FIG. The assembly of the rear car body 2 can be performed by an operation reverse to the above-described folding. At this time, the parking mechanism 21 of the rear car body 2 is operated to restrict the rotation of the tire wheel 10 and to prevent the tilting. The mechanism 27 is set to the operating position.

また、折り畳まれた状態の担架３を組み立てて図１０に示す状態とし、この担架３の組み立ても両パイプ３１を直線状に延ばすと共に、一対の連結板３５ａを直線状に延ばすことで行うことができる。そして、この状態で担架３のシート３ｂ上に負傷者を載せ、救助者２人で担架３のグリップ３３を握って持ち上げ、近くに駐輪状態（脚部３４が路面Ｒに接触し駐輪機構２１が作動状態で図３の二点鎖線ａで示す状態）としてあるリヤカー本体２上に載置する。   The folded stretcher 3 is assembled into the state shown in FIG. 10, and the stretcher 3 can be assembled by extending both pipes 31 linearly and extending the pair of connecting plates 35a linearly. it can. In this state, an injured person is placed on the seat 3b of the stretcher 3, and two rescuers hold the grip 33 of the stretcher 3 and lift it up, and in the nearby parking state (the leg 34 comes into contact with the road surface R and the parking mechanism) 21 is in the operating state and is placed on the rear car body 2 in a state indicated by a two-dot chain line a in FIG.

このとき、担架３のシート３ｂ上に負傷者が乗せられると、反った状態の支持フレーム３ａの長手方向中央部が負傷者の重さにより沈んで略水平状態となる。そして、２人の救助者により担架３をリヤカー本体２の側壁部材５の上方まで持ち上げ、担架３の脚部３４を前壁部材６と後壁部材７の外側に位置させて、負傷者の頭部が後壁部材７側となるようにし、図２に示すように両支持フレーム３ａを前壁部材６と後壁部材７の前記係止部１９に上方から載置係止させる。これにより、担架３がリヤカー本体２上に載置される。   At this time, when an injured person is placed on the seat 3b of the stretcher 3, the longitudinal center portion of the warped support frame 3a sinks due to the weight of the injured person and becomes substantially horizontal. Then, the two rescuers lift the stretcher 3 to above the side wall member 5 of the rear car body 2 so that the legs 34 of the stretcher 3 are positioned outside the front wall member 6 and the rear wall member 7, thereby The support frame 3a is placed and locked on the front wall member 6 and the locking portion 19 of the rear wall member 7 from above as shown in FIG. As a result, the stretcher 3 is placed on the rear car body 2.

この担架３の両支持フレーム３ａを前壁部材６と後壁部材７の係止部１９の一対の係止部材１９ｂ、１９ｃにそれぞれ係止させることで、支持フレーム３ａの幅方向への移動が規制される。また、支持フレーム３ａの前後方向の移動は、図６に示すように、脚部３４の内端面が前記ブロック１９ａを含む係止部１９もしくは前壁部材６や後壁部材７の上部外面に当接して規制される。このとき、担架３の前後の脚部３４の間隔と前壁部材６と後壁部材７の間隔が略同一の場合は、２つの脚部３４により担架３の前後方向の移動が規制される。また、前後の脚部３４の間隔が大きくても、一方の脚部３４を前壁部材６か後壁部材７に当接させることで前後方向への移動が規制されることになる。   By moving both the support frames 3a of the stretcher 3 to the pair of locking members 19b and 19c of the locking portions 19 of the front wall member 6 and the rear wall member 7, the support frame 3a can be moved in the width direction. Be regulated. Further, as shown in FIG. 6, the movement of the support frame 3a in the front-rear direction is such that the inner end surface of the leg 34 abuts against the locking portion 19 including the block 19a or the upper outer surface of the front wall member 6 or the rear wall member 7. Regulated in contact. At this time, when the distance between the front and rear legs 34 of the stretcher 3 and the distance between the front wall member 6 and the rear wall member 7 are substantially the same, the movement of the stretcher 3 in the front-rear direction is restricted by the two legs 34. Even if the distance between the front and rear leg portions 34 is large, the movement in the front-rear direction is restricted by bringing one leg portion 34 into contact with the front wall member 6 or the rear wall member 7.

また、担架３をリヤカー本体２上に載置する際に、負傷者の頭部が高さの高い後壁部材７側となるため、頭部の重さでリヤカー本体２の後壁部材７側が路面Ｒ方向に急に傾動する場合もあり得るが、この傾動は、図３の二点鎖線ｂで示すように、前記傾動防止機構２７の所定長さのロッド２７ｂの当接板２７ａが路面Ｒに当接することで略水平位置に抑えられる。そして、担架３が載置されたら、傾動防止機構２７を収納位置に設定すると共に、駐輪機構２１を非作動位置に設定して、ハンドル８の握持部８ａを握りながらハンドル８を持ち上げて、図３の実線ｃで示すようにリヤカー本体２を路面Ｒに対して略平行な走行状態として、ハンドル８を例えば押すことによりリヤカー本体２を移動させる。   Further, when placing the stretcher 3 on the rear car body 2, the head of the injured person becomes the side of the rear wall member 7 having a high height. In some cases, the vehicle may incline suddenly in the direction of the road surface R. As shown by a two-dot chain line b in FIG. It is suppressed to a substantially horizontal position. When the stretcher 3 is placed, the tilt prevention mechanism 27 is set to the storage position, the parking mechanism 21 is set to the non-operation position, and the handle 8 is lifted while grasping the gripping portion 8a of the handle 8. As shown by the solid line c in FIG. 3, the rear car main body 2 is set in a traveling state substantially parallel to the road surface R, and the rear car main body 2 is moved by pushing the handle 8, for example.

この移動時に、リヤカー本体２は比較的大きなタイヤ車輪１０の回転で移動することから、移動させるための力を軽くでき、救助者一人による移動が可能になると共に、リヤカー本体２を後壁部材７側に押して移動させることから、移動操作時に担架３上の負傷者の顔色を確認しつつ行うことができて、負傷者の安全な移動が可能になる。なお、担架３を載置したリヤカー本体２の移動は、救助者二人で行うことも勿論可能であり、その際は後壁部材７側を持つ救助者が負傷者の様子を確認しつつ、リヤカー１を移動操作する救助者がハンドル８を牽引することで行えば良い。   During this movement, the rear car body 2 moves with the rotation of the relatively large tire wheel 10, so that the force for movement can be reduced, and the movement by one rescuer is possible, and the rear car body 2 is attached to the rear wall member 7. Since it moves by pushing to the side, it can be performed while confirming the face color of the injured person on the stretcher 3 during the moving operation, and the injured person can move safely. Of course, the movement of the rear car body 2 on which the stretcher 3 is placed can be performed by two rescuers. In this case, the rescuer having the rear wall member 7 side confirms the state of the injured person, A rescuer who moves and operates the rear car 1 may pull the handle 8.

このように、前記リヤカー１によれば、リヤカー本体２の荷台部４上方の４隅に、担架３の左右一対の支持フレーム３ａが係止される係止部１９がそれぞれ設けられ、この係止部１９で前壁部材６及び後壁部材７上に載置された担架３の幅方向の移動が規制されると共に、前壁部材６と後壁部材７の上部で担架３の前後方向の移動が規制されるため、リヤカー本体２の荷台部４上方に災害発生時に負傷者を載せた担架３を安定載置した状態で、ハンドル操作によるタイヤ車輪１０の回転でリヤカー本体２をスムーズに移動でき、負傷者を安全な場所まで素早く効率良く運搬できると共に、リヤカー本体２を一人の救助者でも容易に移動できて、救助者への負担を軽減させることができる。   As described above, according to the rear car 1, the locking portions 19 for locking the pair of left and right support frames 3a of the stretcher 3 are provided at the four corners above the loading platform 4 of the rear car body 2, respectively. The movement in the width direction of the stretcher 3 placed on the front wall member 6 and the rear wall member 7 is restricted by the portion 19, and the stretcher 3 moves in the front-rear direction above the front wall member 6 and the rear wall member 7. Therefore, the rear car body 2 can be smoothly moved by the rotation of the tire wheel 10 by the steering wheel operation in a state where the stretcher 3 on which the injured person is placed is stably placed above the loading platform 4 of the rear car body 2. The injured person can be transported quickly and efficiently to a safe place, and the rear car body 2 can be easily moved even by a single rescuer, and the burden on the rescuer can be reduced.

また、前壁部材６と後壁部材７の幅方向上部両端部にそれぞれ設けられた係止部１９の高さ位置が前壁部材６と後壁部材７とで互いに異なると共に、前壁部材６と後壁部材７の上部に担架３の脚部３４が当接することで担架３の前後方向に移動が規制されるため、担架３を荷台部４上方に最適角度で安定載置できて、担架３上の負傷者に安心を与えつつ安定した姿勢で運搬することができる。   The front wall member 6 and the rear wall member 7 have different height positions of the locking portions 19 provided at both upper ends in the width direction of the front wall member 6 and the rear wall member 7. Since the leg part 34 of the stretcher 3 abuts on the upper part of the rear wall member 7 and the movement of the stretcher 3 is restricted in the front-rear direction, the stretcher 3 can be stably placed above the loading platform 4 at an optimum angle. 3 can be transported in a stable posture while giving relief to the injured.

特に、係止部１９が内外一対の係止部材１９ａ、１９ｂをそれぞれ有し、外側の係止部材１９ａの高さが内側の係止部材１９ｂより高く設定されているため、駐輪しているリヤカー本体２に担架３を載置する際に、担架３の一対の支持フレーム３ａを一対の係止部材１９間に上方から簡単に載置できると共に、高さの高い外側の係止部材１９ａで担架３のリヤカー本体２上からの脱落を確実に阻止することができる。また、載置した担架３を安全な避難場所等で降ろす際に、担架３を少し斜めとすることで一方の高さの低い内側の係止部材１９ｂとの係止状態を解除しつつ外側の係止部材１９ａによる係止も解除できて、担架３の持ち上げ高さをできるだけ低くした状態で降ろすことができ、その作業を容易かつ安全に行うことができる。   In particular, the locking portion 19 has a pair of inner and outer locking members 19a and 19b, and the height of the outer locking member 19a is set higher than that of the inner locking member 19b. When the stretcher 3 is placed on the rear car body 2, the pair of support frames 3a of the stretcher 3 can be easily placed between the pair of latching members 19 from above, and the outer latching member 19a having a high height can be used. It is possible to reliably prevent the stretcher 3 from falling off the rear car body 2. Further, when the placed stretcher 3 is lowered at a safe evacuation place or the like, the stretcher 3 is slightly inclined to release the latched state with one of the inner latching members 19b having a low height. The locking by the locking member 19a can also be released, and the stretcher 3 can be lowered with the lifting height as low as possible, and the operation can be performed easily and safely.

さらに、担架３が載置される前壁部材６と後壁部材７の高さが異なった形状で識別できるように構成されているため、リヤカー本体２の組み立て時の誤った取り付けを防止できて、リヤカー本体２を素早く組み立てできると共に、前壁部材６と後壁部材７を補給部品とすることにより、既存するリヤカー本体２に適用して、防災用のリヤカー１を安価なコストで簡単に構築することができる。   Further, since the height of the front wall member 6 and the rear wall member 7 on which the stretcher 3 is placed can be identified by different shapes, it is possible to prevent erroneous attachment when the rear car body 2 is assembled. The rear car body 2 can be assembled quickly, and the front wall member 6 and the rear wall member 7 are used as supply parts, so that the rear car 1 for disaster prevention can be easily constructed at low cost by applying it to the existing rear car body 2. can do.

また、側壁部材５の下端前端部に所定高さの脚２８がそれぞれ設けられると共に、側壁部材５の下端後端部に折り畳み可能な傾動防止機構２７がそれぞれ設けられているため、脚２８が路面Ｒに当接することで安定した駐輪状態が得られると共に、傾動防止機構２７が路面Ｒに当接することで、駐輪中のリヤカー本体２に負傷者が乗った担架３を載置した際のリヤカー本体２の反ハンドル８側への急な傾動を規制して負傷者の頭部が低くなること等を防止でき、運搬時等の負傷者の不安を解消することができる。   Further, a leg 28 having a predetermined height is provided at the lower end front end portion of the side wall member 5 and a foldable prevention mechanism 27 is provided at the lower end rear end portion of the side wall member 5. A stable parking state is obtained by abutting R, and the tilt prevention mechanism 27 abuts the road surface R, so that the stretcher 3 on which an injured person is placed is placed on the rear car body 2 during parking. The sudden tilt of the rear car body 2 toward the side opposite to the handle 8 can be restricted to prevent the head of the injured person from being lowered, and the anxiety of the injured person during transportation can be eliminated.

また、一方の側壁部材５の外面に駐輪機構２１を設けているため、この駐輪機構２１を操作することでタイヤ車輪１０の回転を規制することができ、脚２８と併せて駐輪時のリヤカー本体２の移動を確実に阻止して、負傷者が乗せられた担架３をリヤカー本体２上に安定して載置することができる。特に、駐輪機構２１の押圧部材２５をタイヤ車輪１０の下半分の外周面に当接させることで、タイヤ車輪１０の回転を効果的に規制でき、路面Ｒの状況に係わらず一層安定した駐輪状態を得ることができる。   Further, since the parking mechanism 21 is provided on the outer surface of the one side wall member 5, the rotation of the tire wheel 10 can be regulated by operating this parking mechanism 21. The rear car body 2 can be reliably prevented from moving, and the stretcher 3 on which an injured person is placed can be stably placed on the rear car body 2. In particular, when the pressing member 25 of the parking mechanism 21 is brought into contact with the outer peripheral surface of the lower half of the tire wheel 10, the rotation of the tire wheel 10 can be effectively controlled, and the parking can be performed more stably regardless of the road surface R. A ring state can be obtained.

また、ハンドル８が握持部８ａと支持部８ｂを有する平面視略コ字状に形成され、握持部８ａの下方近傍に担架３の前端部が位置するため、ハンドル８の内側への救助者の進入を防止できて、担架３を載置したリヤカー本体２の移動時の作業の安全性を十分に高めることができる。またさらに、担架３の一対の支持フレーム３ａが折り畳み可能に構成されると共に、支持フレーム３ａの前後を連結し下方に窪んだ凹部３６を有する連結フレーム３５が折り畳み可能に構成されて、前後方向と幅方向にそれぞれ折り畳み可能であるため、担架３の使用後の防災倉庫等への保管の省スペース化が図れて、折り畳み式のリヤカー本体２と共に簡単に保管できる等、使い勝手に優れたリヤカー１を得ることができる。   Further, the handle 8 is formed in a substantially U shape in plan view having the gripping portion 8a and the support portion 8b, and the front end portion of the stretcher 3 is located near the lower portion of the gripping portion 8a. It is possible to prevent the person from entering, and to sufficiently increase the safety of the work when the rear car body 2 on which the stretcher 3 is placed is moved. In addition, the pair of support frames 3a of the stretcher 3 is configured to be foldable, and the connection frame 35 having a recess 36 that is connected to the front and back of the support frame 3a and is recessed downward is configured to be foldable. The rear car 1 can be folded in the width direction so that it can be saved in a disaster prevention warehouse after use of the stretcher 3 and can be easily stored together with the folding rear car body 2. Can be obtained.

なお、前記実施形態においては、前壁部材６の高さを側壁部材５と略同一にし後壁部材７を前壁部材６より高く設定したが、例えば後壁部材７の高さを側壁部材５と略同一にし前壁部材６をこれより低く設定するようにしても良い。この場合は、担架３が前壁部材６及び後壁部材７上に載置された際に、その幅方向両側に側壁部材５の上部が位置することになって、例えば担架３に乗せられた負傷者が側壁部材５の上部を掴むことができ、移動時の負傷者の不安を解消することができる。勿論、前壁部材６と後壁部材７の高さが前記実施形態の場合においても、側壁部材５の上部に把手等を着脱可能に配設することでも、同様の作用効果を得ることができる。   In the above embodiment, the height of the front wall member 6 is substantially the same as that of the side wall member 5, and the rear wall member 7 is set higher than the front wall member 6. However, for example, the height of the rear wall member 7 is set to the side wall member 5. The front wall member 6 may be set lower than this. In this case, when the stretcher 3 is placed on the front wall member 6 and the rear wall member 7, the upper portions of the side wall members 5 are located on both sides in the width direction, for example, placed on the stretcher 3.
