Description

  The present invention relates to a stretcher. More particularly, the present invention relates to a stretcher for carrying an injured person, a sick person, etc. on a sheet part.

  As shown in FIG. 7, the stretcher 51 is generally provided with a rectangular sheet portion (also referred to as a stretcher portion) 54 for placing a person on an upper portion of a carriage 53 having casters 52 (also referred to as a stretcher portion). For example, refer to JP 2002-17786. Some stretchers adjust the height of the seat part by moving the carriage up and down vertically, and the upper part of the person sleeping on the seat part can be raised by tilting the half of the seat part upward In addition, there is a wheelchair that can be changed in shape by folding the seat at two locations. Many stretchers are of any type as described above, so that when the person P is placed on the flat sheet portion 54 as shown, the person P does not fall. Side guards 55 are attached at positions close to both sides. Although it is called a side rail in the above publication, it is disposed on a stretcher for the same purpose as the side guard 55.

  The side guard 55 shown in FIG. 7 is composed of a gate-shaped pipe frame, and has two leg portions 57 that are separated from each other in the longitudinal direction of the seat portion 54. A lower end of the leg portion 57 is attached to a pipe member 56 which is one member constituting the carriage so as to be swingable outward. Specifically, as shown in FIG. 8 which is a side view thereof, the side guard 55 swings outward between a position standing in the vertical direction with respect to the pipe member 56 and a position hanging downward. It is attached as follows. The pipe member 56 constitutes a part of the carriage 53 and extends along the periphery of the seat portion 54.

  When a person is placed on the seat portion 54, the side guard 55 is erected in the vertical direction, and in this state, the side guard 55 is fixed to the carriage 53 by a positioning pin 58 or the like. The side guard 55 exhibits the function of preventing the fall when the side guard 55 is erected in this manner. When a person is placed on the seat portion 54 and when a person is moved from the seat portion 54 to a bed or the like, the side guard 55 is suspended downward so as not to obstruct the transfer operation.

Japanese Patent Laid-Open No. 2002-17786

  As shown in FIG. 8, the conventional side guard 55 is formed into a flat surface. That is, the leg portion of the portal side guard 55 is formed in a straight line. Therefore, when the side guard 55 is erected, the leg portion 57 is in a state of extending straight upward from the pipe member 56 through the vicinity of the side of the seat portion 54. The space Ss between the leg portion 57 and the side of the seat portion 54 is very small.

  Therefore, when the side guard 55 is raised after the injured person or the like is placed on the seat part 54, the arm or the finger of the injured person or the like may be sandwiched between the leg part 57 and the side of the seat part 54. When the user is in a hurry, the side guard 55 is suddenly raised, so that there is a risk that the arm or finger that is pinched may be injured.

  This invention is made in order to solve this subject, and it aims at providing the stretcher which does not have a possibility of pinching the human body on a seat part, even when a side guard is stood | raised rapidly.

  For the above purpose, even when the side guard is in the upright position, the stretcher should be used so that there is sufficient space between the side guard and the side of the seat to prevent the person's arms and fingers from being pinched. What is necessary is just to comprise.

The stretcher of this invention
A carriage, and a seat portion for mounting a person attached to the carriage, and a side guard that is located on a side of the seat portion and is swingably attached from a standing position to the outside. And
At the position where the side guard is erected, the side guard part facing the side of the seat part is outward so that a space where a part of the human body can enter is formed between the side guard and the side part of the seat part. It is curved.

  The side guard is swingably attached to the carriage and extends in a direction away from the side of the seat part, and along the side of the seat part so as to connect the vertical frame members to each other. In a stretcher formed of a frame having a horizontal frame member that extends, at the position where the side guard is raised, the vertical frame member is placed between the side of the seat portion and a part of the human body. Can bend outwards to create a space into which can enter.

  An arbitrary part inside the curved part of the side guard in a standing state and above the side part of the seat part is at least 2 cm away from the nearest part of the side part of the opposing sheet part. Is preferred.

  According to this invention, when a person is placed on the seat portion and the side guard is raised, even if the person's arm or finger is between the side guard and the side of the seat portion, the side guard is curved outward. As a result, a sufficient space is generated between the side guard and the side of the seat portion without pinching the arms and fingers.

  Hereinafter, the present invention will be described in detail based on preferred embodiments with appropriate reference to the drawings.

  FIG. 1 is a perspective view showing an embodiment of the stretcher of the present invention. FIG. 2 is a front view of the stretcher of FIG. FIG. 3 is a side view of the stretcher of FIG.

  The stretcher 1 includes a carriage 3 having a caster 2 at its lower end, and a rectangular plate-like sheet portion 4 attached to the upper end of the carriage 3. A pipe member 5 constituting a part of the carriage 3 extends along the peripheral edge of the seat portion 4 so as to surround the seat portion 4 with a slight distance from the seat portion 4. The portion of the pipe member 5 along both sides of the seat portion 4 is such that the middle portion in the longitudinal direction is lowered below the seat portion 4, and the portions near both end portions in the longitudinal direction and the front and rear end sides of the seat portion 4. The facing part is bent at a predetermined portion so as to be substantially the same height as the seat part 4. The operator pushes and moves the stretcher while holding the portion of the pipe member that is substantially the same height as the seat portion 4. Moreover, the side guard 6 is attached to the intermediate part slightly lowered of the pipe member 5 so as to be swingable outward. The side guard 6 is attached to the seat portion 4 to prevent a person sleeping on the seat 4 from falling.

  As shown in FIGS. 2 and 4, the side guard 6 connects two vertical frame members (hereinafter referred to as leg portions) 7 spaced apart in the longitudinal direction of the seat portion 4 and the upper end portions of the leg portions 7. The horizontal frame member 8 extending along the side of the seat portion 4 and the intermediate frame member 9 extending in parallel to the horizontal frame member 8 and connected to the leg portions 7 below the horizontal frame member 8 are integrally formed. A pipe frame structure. When the lower ends of the two leg portions 7 are rotatably attached to the pipe member 5, the side guard 6 hangs downward from the vertical position with respect to the pipe member 5 as shown in FIG. 3. It is possible to swing outward between the positions. The side guard 6 having such a configuration prevents a person on the seat portion 4 from being laterally moved by the side guard 6 and falling when the side guard 6 is in a standing position (so-called working position). In addition, the said leg part 7 is not limited to two, You may provide three or more.

  The side guard 6 may be fixed at a position extending outward in the horizontal direction instead of the position hanging down or together with the position. By fixing in a horizontal position, for example, when a person is transferred to or from a bed, the bridge functions.

  A mechanism for attaching the side guard 6 to the pipe member to be swingable as shown in FIGS. 4 and 5 will be described below. A rotating member 10 is externally fitted to the pipe member 5 so as to be rotatable, and a lower end of the leg portion 7 is fitted to an engaging convex portion 11 projecting from the rotating member 10. In order to fix the side guard 6 to the pipe member 5 in an upright state, a through hole 12 is formed in the vicinity of the lower end of the leg 7, a positioning hole 13 is formed in the pipe member 5, A positioning pin 14 to be fed is prepared. Reference numeral 15 denotes a bracket projecting from the leg portion 7 to provide the through hole 12, and reference numeral 16 is fitted to the pipe member 5 to reinforce the pipe member 5 in order to form the positioning hole 13. Reinforcing pipe. As described above, in order to fix the side guard 6 also in the horizontal position, another positioning hole is formed in the corresponding portions of the pipe member 5 and the reinforcing pipe 16. The rotating member 10 and the reinforcing pipe 16 are both configured to be split into two parts, and can be easily attached to and detached from the pipe member 5.

  As can be seen from FIG. 5, the leg portion 7 of the side guard 6 has a curved shape, unlike the conventional leg portion 57 (FIG. 8). As for the side guard 6 in a standing state, it is curved outward. Specifically, the sheet portion 4 is curved in a substantially arc shape outward and upward from the pipe member 5 located below the side of the seat portion 4 and continuously overlaps the pipe member 25 in plan view. It is a shape that curves so as to return to the side, then curves in the opposite direction and extends vertically upward. This vertically extending portion (vertical portion) 18 overlaps the pipe member 5 in plan view. The vertical portion 18 prevents a person on the seat portion 4 from moving outward more than the seat portion 4. The curved portion of the leg portion 7 is called a bending portion and indicated by reference numeral 17.

  Due to the curved portion 17, a space S larger than that of the conventional stretcher 51 (FIGS. 7 and 8) is created between the standing side guard 6 and the side of the seat portion 4. In this space S, the side guard 6 is inadvertently raised suddenly without noticing that a person with a thick arm laid down on the seat part hangs his arm outward from the side of the seat part 4. Even in such a case, the dimensions are such that the arm is not clamped between the side guard 6 and the side of the seat portion 4.

  For example, as shown in the cross section in FIG. 5, the leg portion 7 is formed so as to draw a substantially circular arc centering on the position (side end) closest to the leg portion 7 on the side of the seat portion 4. May be. If the leg portion 7 is formed in an arc shape, any part inside the curved portion 17 of the leg portion 7 that faces the side end of the seat portion 4 is separated from the side end of the seat portion 4 by substantially the same distance. Therefore, it is preferable that the separation distance be set to a diameter of a human arm normally considered (about 10 cm) or larger. That is, the curved portion 17 has a shape along a circle having a radius of about 10 cm with the side edge of the sheet portion 4 as the center. This distance is preferably 12 cm or more, more preferably 15 cm or more. From the viewpoint of preventing finger narrowing, this distance is preferably 2 cm or more, and more preferably 3 cm or more. This distance is usually 30 cm or less.

  The curved portion 17 need not be limited to an arc shape. For example, the leg 7 may be bent at an angle depending on the processing method or the like of the leg 7. Even in such a case, it is preferable that the curved portion is shaped so that any portion inside thereof is separated from the side end of the sheet portion 4 by at least about 10 cm. In short, a space S is formed between the side of the seat portion 4 and the standing side guard 6 so as to prevent a person's arm or finger lying on the seat portion from being pinched. Just do it.

  Therefore, for example, as shown in FIG. 6, the pipe member 25 constituting a part of the carriage is hardly separated in the vertical direction from the seat portion 4, and the height position of the swing fulcrum of the side guard 26 is also the height of the seat member 4. When it is almost the same as the side, the leg portion 27 of the side guard 26 is preferably shaped as shown. In other words, the bending portion 28 when the side guard 26 is raised will be described. The bending portion 28 extends from the attachment position to the pipe member 25 outward in the lateral direction by about 10 cm, and then curves upward in an arc shape so as to be seen in plan view. 25, a shape having a vertical portion 29 that returns to the side of the seat portion 4 to a position overlapping with 25, then curves in the opposite direction and extends vertically upward therefrom. Even when the side guard 26 is erected, a sufficient space S is secured between the curved portion 28 and the side of the sheet member 4 so as not to sandwich an arm or a finger.

  The side guards 6 and 26 described above are both formed from a pipe frame, but the present invention is not limited to this configuration. It may be a frame formed from a bar material, may be a pipe or a frame made of a saddle material, and may be formed from a plate material. When a plate material is used, the bending and bending of the leg portion described above is also applied to this plate material.

  Both of the side guards 6 and 26 described above are curved outward from the pipe member. However, when the positioning pin is removed and the side guards 6 and 26 are hung downward, the side guards 6 and 26 enter the inner side of the swing fulcrum (attachment position to the pipe member). There is no worry of interference with other objects such as beds.

  The present invention includes a side guard that can swing between a state in which it is set in an operation position to prevent a person on the vehicle from falling and a position extending outward in the horizontal direction or a position hanging downward. Can be applied to stretchers.
