  However, in the care shifter of Patent Document 2, the tip of the support arm supports the back from the armpit of the cared person, but when the cared person sitting on the suspension leans against the support arm, the support arm is movable to the left and right. The arm could open and the cared person could fall.

  The present invention has been made to solve the above-described problems, and can improve safety in a state where the cared person is sitting and can easily assist the caregiver in getting on and off the cared person. It is an object to provide a nursing care shifter.

In the present invention, means for solving the above problems are as follows.
According to a first aspect of the present invention, there is provided a base that has moving means, a support that is erected from the support, and an upper body of a human body that protrudes horizontally from the support and moves up and down along the support by a lifting mechanism. It consists of a pair of left and right support arms for supporting, a support band for supporting the lower body of the human body is suspended between the two support arms, and a joint portion is formed at an intermediate position of each of the support arms, The open and closed states of the two support arms can be selected by the rotation of the joint portions, and the rotation shafts of the joint portions are formed to be inclined with respect to the support arms. The both support arms are closed as the tip side is lowered, and the human body applies a load to the support band by attaching the support bands to the tip side of the joints in the both support arms. Conjunction with, characterized by the two support arms closed.

  According to a second aspect of the present invention, there is provided a lock mechanism having a stopper that is stretched substantially linearly between the support arms to maintain the open state, and an operation portion that switches between the substantially linear shape and the bent shape of the stopper. It is characterized by that.

  According to the first invention, a support band for supporting the lower body of the human body is suspended between the support arms, and a joint portion is formed at an intermediate position between the support arms. The open and closed states of the two support arms can be selected by the above, the rotation shafts of the joints are formed to be inclined with respect to the support arms, and the tip sides of the support arms are lowered downward. The both support arms are closed, and the support bands are attached to the front end side of the joints in the both support arms, so that the two support arms are moved in conjunction with the load applied to the support band by the human body. In order to be in the closed state, in the state where the cared person is seated, the closed state is firmly maintained by the weight of the cared person, and even if the cared person leans, the support arm opens and the cared person falls backward Door without, it is possible to ensure the safety of the caregiver.

  According to a second aspect of the present invention, there is provided a lock mechanism having a stopper that is stretched substantially linearly between the support arms to maintain the open state, and an operation portion that switches between the substantially linear shape and the bent shape of the stopper. As a result, even if the cared person is seated on the support band, both the support arms do not suddenly close, and after the cared person's body has completely entered between the two support arms, the two support arms can be closed. It is possible to place the cared person on the care shifter safely and easily.

It is a side view of the care shifter. It is a front view of the care shifter. It is a top view which shows the support arm and locking mechanism of the care shifter.

Hereinafter, the nursing care shifter 1 which concerns on embodiment of this invention is demonstrated.
FIG. 1 is a perspective view of the care shifter 1. However, the operation part 16 (refer FIG. 5) of the locking mechanism mentioned later is abbreviate | omitted.
3 is a side view of the care shifter 1, and FIG. 4 is a front view of the care shifter. However, the support band 10 (refer FIG. 1) mentioned later is abbreviate | omitted.

  As shown in FIG. 1, the base 2 of the care shifter 1 is a U-shaped or U-shaped frame, and is grounded by providing wheels 2 a below the four corners thereof. Making it easy to move. The width of the left and right sides of the base 2 is set wider than the width of a pair of support arms 3 and 3 which will be described later, and the stability is improved to prevent falling.

A single support column 4 stands vertically from the center of the base 2, and an arm base 5 is attached so as to surround the outer periphery thereof. The column 4 has a square cross section, and a wheel-shaped guide roll provided on the arm base 5 comes into contact with the outer wall and rolls up and down to slide up and down. The arm base 5 moves up and down electrically with respect to the column 4. Can be done.
A motor 6 for moving the arm base 5 up and down is provided at the upper end of the column 4.
Further, a side column 7 is erected at the right corner of the base 2, and a control controller 8 connected to the motor 6 is attached to the side column 7 so that the arm base 5 can be moved up and down. (Refer to the broken line portion in FIG. 3). A power plug extends from the control controller 8 as shown in FIG.

As shown in FIG. 1, a pair of left and right support arms 3, 3 set at an interval slightly wider than the lateral width of the human body protrudes substantially horizontally from the left and right ends of the arm base 5.
A joint portion 9 made of a hinge or the like is provided at an intermediate position of each support arm 3, and the joint portion 9 is pivoted inward so that the distance between the tips of the support arms 3 is narrower than the width of the human body. It can be.
A back support portion 3a bent inward is provided at the tip of each support arm 3, and plays a role of supporting the back of the care recipient in the closed state of the support arm 3, as shown in FIG.

As shown in FIG. 5, the joint portion 9 provided in each support arm 3 is inclined about 45 degrees inward in the width direction with respect to each support arm 3. 3 is slightly upward, and in the closed state, each support arm 3 is inclined downward. Thereby, as the front end side of the support arm 3 is lowered, both the support arms 3 are closed as shown in FIG. 2, FIG. 3 broken line part and FIG. 5 broken line part.
As shown in FIGS. 1 and 2, a support band 10 is detachably suspended between the support arms 3 via a hook or the like on the distal end side of the joint portion 9. The support band 10 carries the buttocks or the knees when the care recipient gets on the care shifter 1. The support band 10 is appropriately provided with a cushioning material 10a and the like.

In this care shifter 1, when the care recipient sits on the support band 10 and applies a load, the suspended support band 10 applies a downward force to the support arms 3 and 3. Since both the supporting arms 3 and 3 are formed so as to be tilted downward, the force applied to the both supporting arms 3 and 3 rotates the joint portion 9 inward to close the both supporting arms 3 and 3. Work to keep closed.
Therefore, in this care shifter 1, in the state where the cared person is seated as shown in FIG. 2, the closed state of the support arm 3 is firmly maintained by the weight of the cared person. Even if it leans on, the support arm 3 does not open and the cared person does not fall backward, and the safety of the cared person can be ensured.

  However, when the caregiver puts the cared person on the care shifter 1, the cared person's body enters between the support arms 3 and 3 almost simultaneously with the caregiver sitting on the support band 10. Therefore, if both the support arms 3 and 3 are closed in conjunction with the load applied to the support band 10, the both support arms 3 and 3 are closed before the cared person's body has fully entered, which may cause inconvenience. There is also sex.

Therefore, the care shifter 1 according to the embodiment of the present invention is provided with a lock mechanism that maintains the open state of both the support arms 3 and 3 when the care receiver is placed.
As shown in FIG. 5, in this locking mechanism, the stopper 11 made of a plurality of bar members can be stretched between the support arms 3 and 3 on the tip side of the joint portion 9 to maintain the open state. The stopper 11 has a central central member 12 and one end rotatably fixed to both ends of the central member 12 by a predetermined angle, and the other end rotatably fixed to the left and right support arms 3 and 3, respectively. It consists of a pair of both wing members 13 and 13.

A rod-like checker member 14 is fixed to the central member 12, and when the checker member 14 advances and retreats in the front-rear direction, the stopper 11 is arranged in a substantially straight line and is stretched between the support arms 3 and 3 to maintain the open state. Alternatively, both wing members 13 and 13 are rotated and the stopper 11 is bent to close both support arms 3 and 3.
The checker member 14 is attached to a fixing member 15 that is stretched over a portion closer to the proximal end than the joint portions 9 and 9 of the support arms 3 and 3 so as to be able to advance and retreat. More specifically, the checker member 14 is connected to the operation unit 16 rotatably attached to the fixing member 15 by a rack and pinion mechanism (not shown), and rotates the handle of the operation unit 16 in one direction. When the checker member 14 moves forward and rotates in the reverse direction, the checker member 14 moves backward (the broken line portion in FIG. 5).

In order for the caregiver to place the cared person on the care shifter 1 from the bed or the like, first, the stopper 11 of the lock mechanism is arranged in a substantially straight line to maintain the open state of both support arms 3 and 3 (FIG. 5). ).
Next, the person to be cared is seated on the end of a bed or the like and the foot is hung forward. Thereafter, the arm base 5 and the support arms 3 and 3 are lowered to the vicinity of the knee of the cared person, one end of the support band 10 is removed from the support arm 3, and the arm is again put on the support arm 3 through the knee of the cared person. When the controller 8 for control is operated in this state and the both support arms 3 and 3 are raised little by little, the support band 10 is stretched by the weight of the cared person, and the force which closes both the support arms 3 and 3 acts. At this time, even if a force to close both the support arms 3 and 3 is applied depending on the weight of the cared person, the stopper 11 of the lock mechanism is stretched between the support arms 3 and 3 to maintain the distance between the support arms 3 and 3. Therefore, the open state is maintained.
Next, after confirming that the body of the cared person has completely entered between the support arms 3 and 3, the operation part 16 of the lock mechanism is rotated to bend the stopper 11, and the weight of the cared person Thus, the support arms 3 and 3 are closed (FIG. 2, FIG. 5 broken line portion). Thereafter, the support arms 3 and 3 are further raised, and the cared person is completely lifted from the bed or the like.

  In order to lower the care recipient from the care shifter 1 with both support arms 3 and 3 closed, the support arms 3 are lowered before the bed or the like so that the care receiver is seated on the end of the bed or the like and locked. The operation part 16 of the mechanism is rotated in the reverse direction to make the stopper 11 substantially linear, both the support arms 3 and 3 are opened, the support band 10 is removed from the support arm 3, and is extracted from below the knee of the cared person.

  As described above, in the care shifter 1 according to the embodiment of the present invention, when the care receiver is placed on the care shifter 1 by providing the lock mechanism, both support is provided even when the care receiver is seated on the support band 10. The arms 3 and 3 do not close suddenly, and both the support arms can be closed after the cared person's body is completely entered between the support arms, so that the cared person can be safely and easily cared for the care shifter 1. Can be put on.
