In the tilted state, the fence 72 is in a state where the top and bottom are almost inverted compared to the state shown in FIG.

  Next, the detailed structure of the connection part 14 provided in the 1st stretcher 1 is demonstrated. As described above, a pair of connecting portions 14 are provided on one side surface in the longitudinal direction of the carriage frame 11, but since these two have the same configuration, only the configuration on one side will be described, while the other The description of the configuration on the side is omitted.

  FIG. 3 is a schematic plan view showing the configuration of the connecting portion 14 included in the first stretcher 1 according to the embodiment of the present invention. 3A is a top view and FIG. 3B is a side view. As shown in FIG. 3, the connecting portion 14 includes a flat plate member 141 having a substantially rectangular shape in plan view. An engagement hole 141 a having a substantially circular shape in plan view is provided in a substantially central portion of the flat plate member 141. The engagement hole 141 a is a through hole that penetrates the upper surface and the lower surface of the flat plate member 141. The engagement hole 141a is provided in such a size that the engagement pin 47 (see FIG. 2) provided in a substantially hemispherical shape can be inserted.

  An outer edge member 142 formed by bending a round member is attached to the outer edge of the flat plate member 141. The outer edge member 142 can be formed using, for example, a round pipe or a round bar. As shown in FIG. 3A, the outer edge member 142 is provided along the three sides of the flat plate member 141, and has a substantially U-shape when viewed from above. Further, as shown in FIG. 3B, the outer edge member 142 is provided with a bend B for adjusting the height position of the flat plate member 141. The bending may be omitted depending on circumstances.

  Two distal end portions of the outer edge member 142 provided in a substantially U shape in plan view are connected to the rotation shaft member 143. The rotation shaft member 143 is rotatably supported on one side surface in the longitudinal direction of the carriage frame 11. In the present embodiment, the pair of connecting portions 14 and 14 share one rotating shaft member 143 (see also FIG. 6 described later).

  FIG. 4 is an enlarged schematic perspective view showing a configuration around the connecting portion 14 included in the first stretcher 1 according to the embodiment of the present invention. FIG. 4A is a view when the connecting portion 14 is in the first posture, and FIG. 4B is a view when the connecting portion 14 is in the second posture. The first posture is a posture for connecting the first stretcher 1 to the second stretcher 2. In addition, the second posture is a posture suitable for use of the first stretcher 1 when the first stretcher 1 is not connected to the second stretcher 2.

  As shown in FIG. 4 (see also FIG. 6 and FIG. 7 described later), projecting pieces 111 that rotatably support the rotating shaft member 143 are provided at both ends of one side surface in the longitudinal direction of the carriage frame 11. Is provided. The projecting piece 111 is provided with a first regulating pin 112 that abuts on the outer edge member 142 of the coupling portion 14 to regulate the rotation of the coupling portion 14 in one direction. Due to the presence of the first regulating pin 112, the connecting portion 14 in the first posture maintains the first posture without rotating due to gravity. In the first posture, the connecting portion 14 protrudes in the horizontal direction.

  Further, the projecting piece 111 is provided with a plunger pin 113. The plunger pin 113 normally abuts on the outer edge member 142 of the connecting portion 14 to change the posture of the connecting portion 14 (first posture → second posture or second posture → first posture). not allowed. However, when a force greater than a predetermined force is applied to the connecting portion 14 to rotate the connecting portion 14, the plunger pin 113 retracts the tip of the pin and permits the posture change. The plunger pin 113 is an example of the selection member of the present invention.

  In the present embodiment, in the first posture, the outer edge member 142 is in contact with the first restriction pin 112 but is not in contact with the plunger pin 113. That is, the connecting portion 14 in the first posture has a range in which the connecting portion 14 can be rotated without coming into contact with the plunger pin 113 in the direction from the first posture to the second posture.

  In the second posture, the outer edge member 142 is in contact with the plunger pin 113 by the action of gravity, but the tip of the pin of the plunger pin 113 is not retracted by the action of gravity. For this reason, the connection part 14 maintains the standing posture. In the present embodiment, the second restriction pin 114 is provided to restrict the connecting portion 14 in the second posture from falling to the cart frame 11 side. The second restriction pin 114 may not be provided depending on circumstances.

  FIG. 5 illustrates the movement when the connecting portion 14 included in the first stretcher 1 according to the embodiment of the present invention and the connected portion (engagement pin 47) of the second stretcher 2 are connected. It is a schematic diagram for doing. The connection procedure proceeds in the order of FIG. 5 (a), FIG. 5 (b), FIG. 5 (c), and FIG. 5 (d).

  When connecting the 1st stretcher 1 and the 2nd stretcher 2, as shown to Fig.5 (a), the connection part 14 is made into the 1st attitude | position. In the case of changing from the second posture to the first posture, the assistant applies a force to the connecting portion 14 using, for example, hands or feet. Thereby, the state which retracted the front-end | tip of the plunger pin 113 and the connection part 14 was in the 1st attitude | position is acquired.

  The second stretcher 2 is in a state where the caster 43 is locked and does not move. Moreover, although it is assumed here that the first stretcher 1 is brought close to the second stretcher 2, the reverse may be possible. In this case, the caster 13 on the first stretcher 1 side is locked.

  The connecting portion 14 is brought close to the engaging pin 47 from the posture shown in FIG. In addition, it is preferable to provide a mark on the first stretcher 1 and the second stretcher 2 so that the connecting portion 14 and the engagement pin 47 can be brought close to each other in a correct positional relationship. When the connecting portion 14 is brought close to the engaging pin 47, the connecting portion 14 whose tip is set to be slightly higher than the guide disk 44 comes into contact with the engaging pin 47 as shown in FIG. .

  In this state, when the connecting portion 14 is further moved in the direction approaching the engaging pin 47, the outer edge member 142 starts to ride on the engaging pin 47 as shown in FIG. It rotates in a direction (counterclockwise direction in FIG. 5). Further, when the connecting portion 14 is moved in the same direction, the outer edge member 142 gets over the engaging pin 47, the connecting portion 14 rotates in the opposite direction, and the flat plate member 141 and the engaging pin 47 are in contact with each other. Become. Further, by moving the connecting portion 14 in the same direction, finally, as shown in FIG. 5D, the engagement pin 47 automatically fits into the engagement hole 141 a provided in the flat plate member 141. Thereby, the connection between the connecting portion 14 and the connected portion (engagement pin) 47 is completed.

  Incidentally, as described above, the first stretcher 1 is provided with a pair of connecting portions 14. In the present embodiment, in a state where the first stretcher 1 and the second stretcher 2 are connected, as shown in FIG. 6, each of the pair of connecting portions 14 is connected to the engaging pin 47. Become. For this reason, the two stretchers 1 and 2 are connected in a well-positioned state and are not easily separated. Therefore, in the case where the person requiring assistance is moved between the two stretchers 1 and 2, the person requiring assistance is unlikely to feel anxiety. In addition, when moving a care recipient between two stretchers 1 and 2, it is preferable to apply a caster lock to both of the two stretchers 1 and 2.

When the movement of the person requiring assistance between the two stretchers 1 and 2 is completed and the two stretchers 1 and 2 are separated, as shown in FIG. Is the second posture (standing posture). Thereby, connection with the connection part 14 and the engagement pin 27 is cancelled | released, and the two stretchers 1 and 2 can be cut off. When the connecting portion 14 is in the second posture, the connecting portion 14 is not in a state of protruding in the horizontal direction, so that the assistant is difficult to contact the connecting portion 14. Moreover, the outer edge of the connection part 14 is comprised with the member which rounded. For this reason, even if a helper contacts the connection part 14, possibility that an injury, such as a laceration, will be low is low. Therefore, the assistant can comfortably perform the assistance work without worrying about injury when moving the first stretcher 1.
<Others>

  The embodiment described above is merely an example of the present invention. The configuration of the embodiment described above may be changed as appropriate without departing from the technical idea of the present invention.

  For example, in the connecting portion 14 described above, a guide groove for guiding the moving direction of the engagement pin 47 may be provided on the lower side of the flat plate member 141 or the outer edge member 142 in some cases.

  Moreover, in embodiment shown above, when connecting two stretchers, the structure which the helper previously made the connection part 14 into the 1st attitude | position was employ | adopted. However, this is only an example. For example, when two stretchers that perform connection are approached, the connection unit may be automatically changed from the second posture to the first posture, and the connection may be completed simultaneously with the posture change. In such a configuration, when the connecting portion changes from the second posture to the first posture, the caster lock of the stretcher including the connecting portion may be configured to operate.

  Moreover, in the above, although the connection structure of this invention showed the structure applied to the connection of the stretcher only for conveyance and the stretcher for bathing, this is only an example. For example, the connection structure of the present invention may be applied to connection between a wheelchair dedicated to transportation (a reclining wheelchair) and a stretcher for bathing. Moreover, for example, the connection structure of the present invention may be applied to connection between a transport-only stretcher and a washing table that is movably connected to the bathtub apparatus. Furthermore, for example, the connection structure of the present invention may be applied to connection between a work table having a transfer function capable of attaching and detaching clothes of a care recipient and a stretcher for bathing. The present invention is widely applicable to the connection between two transfer vehicles, and the transfer vehicle is not limited to a stretcher.
