  The bathing stretcher of Patent Document 1 is effective in that it prevents the person being assisted on the stretcher from accidentally unlocking the side fence. However, if the caregiver transfers the person being assisted from the transfer stretcher or wheelchair to the bathing stretcher of Patent Document 1, or vice versa, the first lock mechanism is not released. Cannot be released. That is, there is a problem that the side fence cannot be unlocked easily and quickly, which is troublesome and low in efficiency for the assistant.

  In view of the above-described problems, an object of the present invention is to provide a stretcher that is improved in convenience and efficiency when assisting a caregiver.

  In order to achieve the above object, a stretcher according to the present invention includes a stretcher body, a first fence disposed on a side portion of the stretcher body, and a second fence disposed on the inner side of the first fence. And the second fence is released from a closed state in which the side of the stretcher body is closed by movement in one direction.

  Further, in the stretcher having the above-described configuration, the stretcher main body is composed of a plurality of parts capable of adjusting the angle, a base member is disposed at a lower portion of the stretcher main body, and the first fence is provided on a side portion of the base member. It is desirable.

  Moreover, in the stretcher having the above-described configuration, it is preferable that the plurality of portions include an upper limb portion, a trunk portion, and a lower limb portion, and the second fence is provided at least on a side portion of the upper limb portion or the trunk portion.

  In the stretcher having the above-described configuration, the second fence has a gripping portion, and the height of the gripping portion with respect to the stretcher main body is substantially the same as the height of the eye of the person being laid down or on the side of the stretcher main body. It is desirable to be set to.

  In the stretcher having the above-described configuration, the first fence is released from the closed state in which the side of the stretcher body is closed by movement in one direction, and the first fence has a direction for releasing the closed state of the first fence, It is desirable that the direction for releasing the closed state of the fence 2 is a different direction.

  According to the present invention, the second fence can be released from the closed state by moving in one direction. Therefore, since the second fence can be easily opened when assisting the person being assisted (when getting on and off the stretcher main body or when the person being assisted is washing), it is not troublesome for the assistant. In addition, when the caregiver takes a bath, the first fence and the second fence are arranged outside and inside the stretcher body to form a double fence, so that the safety of the caregiver is ensured.

FIG. 3 is a view showing a state in which the first fence is removed from the right side view shown in FIG. In the description of FIGS. 1 to 3, the upper side of the observer facing the paper surface of FIG. 1 is “up”, the lower side is “lower”, the left hand side is “left”, the right hand side is “right”, Further, the description will be made assuming that the left hand side of the observer facing the paper surface of FIG.

  The stretcher of this embodiment is a device for placing a caregiver such as an elderly person or a handicapped person. Is a tool to be used. However, the use of the stretcher is not limited to bathing. For example, the stretcher may be used for transporting a person being assisted regardless of bathing, or may be used for both bathing and transporting. It may be used.

  In the present embodiment, the stretcher 1 includes a stretcher body 2 and a base member 3 disposed at the lower part of the stretcher body 2. The stretcher body 2 is composed of an upper limb portion on which the upper limb of the person being assisted is placed, a torso portion on which the torso of the assisted person is placed, and a lower limb portion on which the lower limb of the assisted person is placed. The mat is arranged. The mats arranged on the upper limbs, the trunk, and the lower limbs are referred to as mats 4a, 4b, and 4c, respectively. By providing a flexible mat on the surfaces of the upper limbs, the torso, and the lower limbs, the person being assisted is prevented from feeling uncomfortable by contacting the stretcher body 2 made of stainless steel or the like.

  Assuming that the stretcher of the present embodiment is used at the time of bathing, each mat is desirably formed of a material having water repellency and heat retention, and is formed of, for example, an ethylene vinyl acetate copolymer resin. Further, the stretcher body 2 is provided with a plurality of through holes (not shown), and through holes 41 (in FIG. 1 for simplification of the drawing) at positions corresponding to the through holes of the stretcher body 2 in each of the mats 4a to 4c. By forming the reference numeral 41 for one through hole among the plurality of through holes, hot water on the mat can be flowed to the back side of the stretcher 1. This prevents the person being assisted from feeling uncomfortable when the hot water accumulated on the mat cools.

  At the upper end of the stretcher body 2, a pillow part 5 for placing the person being assisted is placed. The pillow part 5 is arranged so that the position of the pillow part 5 can be adjusted in the vertical direction with respect to the stretcher body 2 so that the pillow part 5 can be in an appropriate position according to the height of the person being assisted. In addition, in order to raise the convenience at the time of hair washing, it is more desirable that the height with respect to the stretcher main body 2 of the pillow part 5 is adjustable. Moreover, the pillow part 5 may be detachable from the stretcher body 2.

  The upper limb, the trunk, and the lower limb are connected to each other via a shaft (not shown), the upper limb is rotatable with respect to the trunk, and the inclination angle of the upper limb with respect to the base member 3 is set in several steps. It can be set as a desired angle (for example, 5 degrees and 25 degrees). Moreover, the connection part of a trunk | drum part and a leg part is comprised so that it can protrude ahead, and it can deform | transform between a flat shape and a mountain shape. By forming a mountain shape between the torso and the lower limbs, the knee of the person being assisted can be raised and the legs can be bent.

  The stretcher body 2 is a belt that presses the body of the person being assisted against the stretcher body 2 from the front of the stretcher body 2 across the right and left sides of the stretcher body 2 to fix the position of the person being assisted 6 is arranged. One belt 6 is disposed on each of the upper limb, the trunk, and the lower limb.

  On both sides of the upper limb part, a tip 7 is bent inward, and a grip 7 to which a rubber material is attached is provided at the tip. The caregiver in the supine position can stabilize his / her posture by gripping the grip 7, and the helper assists the person being assisted by gripping the grip 7 as necessary.

  The base member 3 supports the stretcher body 2 from the back side. First fences 8 are attached to both sides of the base member 3. The first fence 8 is attached to the base member 3 via a rotating shaft, and is attached to the base member 3 so as to be rotatable. More specifically, the first fence 8 stands perpendicularly to the front with respect to the base member 3 to close the side portion of the stretcher body 2 (closed state), and rearward with respect to the base member 3 by its own weight. A lock mechanism is provided that can be rotated between a position (open state) that hangs vertically and opens the side portion of the stretcher body 2 and maintains the closed state. Hereinafter, the locking mechanism of the first fence 8 will be described with reference to FIG.

  FIG. 4 is a view showing the locking mechanism of the first fence 8, and is a schematic view enlarging the locking mechanism portion of the first fence 8 in the right side view of the stretcher shown in FIG. 2. Support members 31 and 32 are erected at the side end of the base member 3. A rotating shaft 33 is disposed between the upper end portion of the support member 31 and the upper end portion of the support member 32. In addition, a convex portion 34 that can be fitted into a concave portion 35 a described later is formed on the surface of the upper end portion of the supporting member 31 that faces the supporting member 32.

  The rotary joint 35 is joined to the first fence 8, and a through hole (not shown) is formed, and the rotary shaft 33 is inserted through the through hole. The rotary joint 35 is rotatable and slidable with respect to the rotary shaft 33, and a concave portion 35 a that can be fitted to the convex portion 34 is formed on the surface of the rotary joint 35 that faces the support member 31. The slide can be slid left and right with respect to the paper surface of FIG. 4, and FIG. 4 shows a state where the rotary joint 35 is slid to the right.

  An engaging portion 36 is provided at the upper end portion of the support member 32, and an engaging portion 37 is provided inside the rotary joint 35. Therefore, when the rotary joint 35 is slid to the right as shown in FIG. 4, the engaging portion 36 and the engaging portion 37 are engaged to prevent the rotary joint 35 from rotating with respect to the rotary shaft 33. It is out. That is, the engaging portion 36 and the engaging portion 37 constitute a lock mechanism that maintains the first fence 8 in the closed state.

  When the first fence 8 is slid in the left direction in this state, the engagement portion 36 and the engagement portion 37 are disengaged, and the concave portion 35 a is fitted to the convex portion 34. In this state, the lock mechanism for maintaining the first fence 8 in the closed state does not work, the rotary joint 35 is rotated with respect to the rotary shaft 33, and the first fence 8 is opened.

  That is, the lock that keeps the first fence 8 closed can be released by moving the first fence 8 in one direction, and the first fence 8 can be opened by releasing the lock. Can do. When the first fence 8 is closed again, the first fence 8 is lifted against gravity, and then the first fence 8 is slid rightward to engage the engaging portion 36 and the engaging portion 37. Can be engaged.

  In this embodiment, the first fence 8 can be unlocked by sliding in the left-right direction (up and down in FIGS. 1 to 3), but the sliding direction is not limited to this. For example, the up-down direction It is good also as unlocking being possible by sliding to the direction (front-back of FIGS. 1-3).

  As described above, the first fence 8 is provided on the base member 3 independent of the stretcher body 2. Therefore, the influence which the angle adjustment of the upper limb part, the trunk part, and the lower limb part of the stretcher body 2 has on the first fence 8 is minimized, and the fence can be made long in the longitudinal direction of the stretcher body.

  Returning to FIGS. 1 to 3, the second fence 9 is provided on both sides of the stretcher body 2. The second fence 9 is a fence that is arranged inside the first fence 8 when the first fence 8 is in the closed state, and closes the side portion of the stretcher body 2. In this embodiment, the 2nd fence 9 is distribute | arranged to the side part of an upper limb part and a trunk | drum part, respectively. The number of the second fences 9 is not particularly limited, but the second fences 9 are provided on the stretcher main body 2 unlike the first fences 8 and are affected by the angle adjustment of the upper limbs, the trunks, and the lower limbs. Therefore, it is difficult to make a long fence straddling each part, and it is a fence that fits the length of each part in the length direction.

  When the caregiver lies on the stretcher body 2, the position of the body with respect to the stretcher body 2 is easily shifted in the upper limbs and the torso. Therefore, the second fence 9 is provided at least on the upper limb or the trunk, so that the safety of the person being assisted is ensured more reliably. In this embodiment, the second fence 9 is provided on the upper limb part and the trunk part, so that the stretcher 1 has higher safety.

  Similarly to the first fence 8, the second fence 9 can release the closed state in which the side portion of the stretcher body 2 is closed by movement in one direction. Hereinafter, the lock mechanism of the second fence 9 will be described with reference to FIG.

  FIG. 5 is a first view showing a lock mechanism of the second fence 9 and is an enlarged schematic view of the lock mechanism portion of the second fence 9 in the right side view of the stretcher shown in FIG.

  The second fence 9 is a substantially U-shaped pipe in a side view, and an accommodation portion 2 a that can accommodate the second fence 9 is formed on a side portion of the stretcher body 2. A through hole 9a is formed in one end of the second fence 9, and a plunger is provided in the recess 2b corresponding to the through hole 9a in the recess 2b into which both ends of the second fence 9 are inserted in the housing 2a. 10 is provided. The plunger 10 is provided in the recess 2b so as to be able to advance and retreat between a position where it is urged toward the second fence 9 and inserted into the through hole 9a and a position where it is not inserted into the through hole 9a.

  When the plunger 10 is inserted into the through hole 9a, the second fence 9 is closed to close the side portion of the stretcher body 2, and when the plunger 10 is removed from the through hole 9a, the second fence 9 is moved to the housing portion 2a. It will be accommodated and will be in the open state which opens the side part of the stretcher main body 2. In FIG. 5, the second fence 9 is in a closed state, and when the plunger 10 is pulled in one direction against the bias, the plunger 10 is detached from the through hole 9a and the second fence 9 is accommodated in the accommodating portion 2a. Is done. On the other hand, when the second fence 9 is changed from the open state to the closed state, the plunger 10 is inserted into the through hole 9a and is locked at that position by grasping and pulling up the second fence 9.

  In the present embodiment, the second fence 9 is an accommodation type (embedded type) that can be accommodated in the stretcher body 2, but the accommodation method is not limited to that described above. For example, the closed state may be released by moving the second fence 9 in one direction. Specifically, when the second fence 9 is in the closed state, the second fence 9 is moved. The lock may be released by lifting (moving forward in FIGS. 1 to 3) and returning to the accommodation position (open state). FIG. 6 is a second view showing the locking mechanism of the second fence 9.

  A rotating member 91 that moves with the movement of the second fence 9 is arranged on the outer wall of the second fence 9. The rotating member 91 is disposed on the second fence 9 via the rotating shaft 92 and is disposed so as to be rotatable with respect to the second fence 9. The rotating member 91 has a shape in which an upper portion and a lower portion are recessed in a mountain shape on the inside (hereinafter, a portion recessed in the mountain shape in the rotating member 91 is referred to as an “engagement portion”).

  A stopper 21 is provided in the recess 2b, and the stopper 21 is provided at a position where the turning member 91 collides when the stopper 21 moves a predetermined length L above the second fence 9. Further, the recess 2b is provided with an engagement hole 22 that can engage with the rotation member 91 and lock the position of the second fence 9. Hereinafter, a process of locking the second fence 9 at a predetermined position will be described. Fig.6 (a) is a figure which shows the state (open state) in which the 2nd fence 9 exists in an accommodation position.

  When the second fence 9 is lifted from the state shown in FIG. 6A, both end portions of the second fence 9 move upward in the recess 2b. With this movement, the rotating member 91 also moves upward. However, when the rotating member 91 moves upward by a predetermined length L, the upper left portion of the rotating member 91 collides with the stopper 21. On the other hand, since the stopper 21 does not collide with any member in the upper right portion of the rotating member 91, the rotating member 91 rotates counterclockwise. And the engaging part of the upper part of the rotation member 91 engages with the stopper 21, and rotation of the rotation member 91 stops and it will be in the state shown in FIG.6 (b).

  Due to the rotation of the rotating member 91 from FIG. 6A to FIG. 6B, the lower right portion of the rotating member 91 protrudes outward from the engagement hole 22 in the state shown in FIG. 6B. When the second fence 9 is lowered (the hand is released from the second fence 9), the lower right portion of the rotating member 91 collides with the lower end portion of the engagement hole 22. On the other hand, since the lower left portion of the rotating member 91 does not collide with any member, the rotating member 91 rotates counterclockwise, and the lower left portion of the rotating member 91 collides with the inner wall surface of the recess 2b. Thus, the rotation of the rotating member 91 stops and the state shown in FIG. The state shown in FIG. 6C is a state where the second fence 9 is locked at a predetermined position, that is, a closed state.

  When the second fence 9 is lifted from the state shown in FIG. 6C, the upper right part of the rotating member 91 (the upper right part in the state shown in FIG. 6A, and the upper left part in FIG. 6C). Collides with the stopper 21 and the state shown in FIG. As a result, the upward movement of the second fence 9 is stopped, and when the second fence 9 is lowered, the lower left portion of the rotating member 91 (the lower left portion in the state shown in FIG. 6 (d), the lower right portion) collides with the lower end of the engagement hole 22. Then, the rotating member 91 rotates counterclockwise, and the state shown in FIG. 6A, that is, the second fence 9 is opened.

  In the present embodiment, the second fence 9 can also be used as a handrail that can be held by the person being assisted and the person being assisted. That is, the central portion of the second fence 9 can be used as a gripping portion, and the height of the gripping portion with respect to the stretcher body 2 is substantially the same as the eye level of the person being laid down or on the side of the stretcher body 2. Is set.

  In the present embodiment, the first fence 8 and the second fence 9 can be released from the closed state of each fence by moving the components constituting the lock mechanism itself or in one direction. In this configuration, if the moving direction for releasing the closed state of the first fence 8 and the moving direction for releasing the closed state of the second fence 9 are the same direction, the person being assisted has the same operation. When performing for each fence, both fences may be open. Therefore, it is desirable that the moving directions for releasing the closed state of each fence are different directions. Taking the locking mechanism as an example, when the first fence 8 is released from the closed state by moving the first fence 8 to the left (downward in FIGS. 1 to 3), It is desirable that the second fence 9 is released from the closed state by moving upward (forward in FIGS. 1 to 3).

  According to the present embodiment, the second fence 9 can be released from the closed state by moving in one direction. Therefore, since the second fence 9 can be easily opened when assisting the person being assisted (when getting on and off the stretcher body or washing the person being assisted), there is no trouble for the assistant. In addition, when the caregiver takes a bath, the first fence 8 and the second fence 9 are arranged on the outside and inside of the stretcher body 2 to form a double fence, so that the safety of the caregiver is ensured. The

  The first fence 8 is provided on the base member 3 independent of the stretcher body 2. Therefore, the angle adjustment of a plurality of parts (upper limb part, trunk part, lower limb part) included in the stretcher main body 2 can minimize the influence on the first fence 8, and therefore the stretcher main body as compared with the second fence 9. The fence can be long in the longitudinal direction.

  In addition, when the person being assisted lies on the stretcher body 2, it is the upper limbs and torso that the body position with respect to the stretcher body 2 is likely to shift. Therefore, in the configuration in which the stretcher main body 2 includes the upper limb portion, the torso portion, and the lower limb portion, the second fence 9 is provided at least in the upper limb portion or the torso portion, thereby ensuring the safety of the person being assisted.

  In addition, the second fence 9 is provided with a gripping portion, and the height of the second fence 9 is set to the level of a caregiver lying on the side of the stretcher body. The posture can be maintained by the assistant holding the grip portion. Therefore, the person being assisted can take a risk avoiding action such as maintaining his posture or preventing submergence.

  Further, since the closed state of both the first fence 8 and the second fence 9 can be released by movement in one direction, the assistant can easily release the closed state of each fence. On the other hand, because the movement direction for releasing each fence is different, it prevents the helped person from releasing the closed state of both fences by performing the same operation on both fences. Can do. Therefore, it becomes a stretcher provided with a fence that is difficult for the care recipient to release the closed state and is easy for the assistant to release the closed state.

Second Embodiment

  In addition, the 2nd fence 9 of this embodiment can cancel | release the closed state which closes the side part of the stretcher main body 2 by the movement to one direction similarly to the 2nd fence 9 of 1st Embodiment. Hereinafter, the lock mechanism of the second fence 9 will be described with reference to FIG. FIG. 7 is a third view showing the locking mechanism of the second fence 9.

  The second fence 9 is a substantially U-shaped pipe in a side view, and a recess 2 b into which both ends of the second fence 9 are inserted is formed on the side of the stretcher body 2. A ball plunger BP (an example of an urging member) is disposed in the recess 2b, and is disposed on the inner peripheral wall of the recess 2b and protrudes inward. When both ends of the second fence 9 are inserted into the recess 2b, the ball plunger BP presses both ends of the second fence 9 against the inner peripheral wall of the recess 2b.

  When both ends of the second fence 9 are inserted into the recess 2b, the second fence 9 is closed to close the side of the stretcher main body 2, and both ends of the second fence 9 are pulled out from the recess 2b. It will be in the open state which open | releases the side part of the stretcher main body 2. FIG. In FIG. 7, the second fence 9 is in a closed state, and both ends of the second fence 9 are pressed by the ball plunger BP when the second fence 9 is in a closed state, so that the second fence 9 is in a closed state. The vibration of the second fence 9 at the time is suppressed, and the second fence 9 can be held in the recess 2b.

  Further, the force for holding the second fence 9 in the recess 2b by the ball plunger BP is set to such an extent that it can be pulled out, and the assistant pulls the second fence 9 from the recess 2b with a force greater than a certain force. Thus, the second fence 9 can be opened.

  According to the present embodiment, the same effects as those of the first embodiment can be obtained.
