As shown in FIG. 7 to FIG. 9, it has an inclined portion 95f in the vertical spiral direction connecting the vertical portion 95g and the horizontal portion 95e.

  That is, when the elevating tube 91a rotates around the vertical axis Lz while the inner edge (inner surface) of the cam groove 95 is in sliding contact with the guide roller 96, the vertical pitch dimension (edge) of the upper edge 95c and the lower edge 95d. The elevating cylinder portion 91a (the rotation member 91) is configured to move up and down with a center point vertical separation dimension.

Further, an outer cylinder member 93 is provided on the elevating cylinder portion 91a so as to be fitted around and is rotatable around the vertical axis Lz.
The outer cylinder member 93 includes an upper cylinder part 93c, a lower cylinder part 93d, and a connecting part 93g that connects the upper cylinder part 93c and the lower cylinder part 93d with a predetermined separation dimension. And between the upper cylinder part 93c and the lower cylinder part 93d, the guide roller 96 is arrange | positioned in insertion shape, and the horizontal opening-shaped window part (slit part) 93k which makes one round along the circumferential direction is formed. Yes.
The guide roller 96 prevents the outer cylinder member 93 from moving up and down and can rotate about the vertical axis Lz while being held at a predetermined height position.

  Then, the upper end side (one end side) is pivotally attached to the seat portion side projecting piece portion 90v projecting from the seat portion 9 (the cylindrical portion 90 thereof) with a horizontal seat portion side connecting axis L9, and the outer cylinder. The interlocking connecting member 92 is pivotally attached to the base side protruding piece 93v protruding from the member 93 with the base side connecting axis L8 parallel to the seat side connecting axis L9 at the lower end side (the other end side). It has.

As shown in FIG. 7, when the seat portion 9 is in the reference seat position and in a horizontal plane posture, the guide roller 96 corresponds to the vertical portion 95g of the cam groove 95, and the rotation member 91 is prevented from rotating. Yes.
When the caregiver grips and lifts the tip edge 9b side of the seat 9, the rotating member 91 is also lifted, and the guide roller 96 corresponds to the upper part of the inclined portion 95f. The portion 9 can be rotated from the reference seat position toward the rear side and the left and right outer sides.

When the seat 9 is rotated about the vertical axis Lz by the caregiver, the rotating member 91 is also rotated about the vertical axis Lz, and the guide roller 96 corresponds to the inclined portion 95f of the cam groove 95. Then, as the cam groove 95 extends along the guide roller 96, the rotating member 91 rises as shown in FIG. When the rotation rises, the rotating member 91 rises, but the outer cylinder member 93 (base-side protruding piece portion 93v) rotates while maintaining a predetermined height position. The side projection piece 90v is pulled downward, the cylindrical portion 90 rotates around the horizontal axis Ly, and the seat portion 9 swings upward from the horizontal plane posture to tilt downward at the proximal end (tilt upward at the distal end). As a result, the vertical posture becomes a standing posture.
That is, the caregiver can change the seat portion 9 to the upright posture by the action of the cam groove 95 (with a small force) without swinging the tip edge portion 9b side of the seat portion 9 upward with a large force.

As shown in FIG. 9, when the horizontal portion 95e of the cam groove 95 corresponds to the guide roller 96, the rotating member 91 does not move up and down even if it rotates about the vertical axis Lz, and the seat portion 9 Is held in an upright posture by the outer cylinder member 93 while the base end edge portion (seat portion side protruding piece portion 90v) of the seat portion 9 is drawn downward.
When the guide roller 96 comes into contact with the lower end edge portion 95d of the cam groove 95, the rotation of the rotating member 91 exceeding the rotation possible angle θz is restricted, and the seat portion 9 is arranged at a predetermined maximum retracted position. Established.

Here, in FIGS. 8 to 10, when the seat 9 (cylindrical portion 90 and support portion 91b) is rotated approximately 180 degrees around the vertical axis Lz from the reference seat position, the guide roller 96 is horizontal from the inclined portion 95f. The seat portion 9 is in a standing posture in a vertical plane corresponding to the shape portion 95e, and after exceeding about 180 degrees, the standing posture of the seat portion 9 is not changed (the vertical plane shape is kept). It is configured to rotate to a position.
Although not shown in the drawings, the cam groove 95 may be provided so that when the seat portion 9 is rotated approximately 90 degrees around the vertical axis Lz, a vertical plane-like standing posture is obtained. Or you may provide so that it may become a vertical planar standing posture in the maximum retracted position.
That is, if the seat 9 is switched from the horizontal plane posture to the upright posture between the reference seat position and the maximum retracted position, the swing timing of the posture of the seat portion 9 and the timing of the end of the swing (the start start time) The moving angle and the standing end turning angle are free.

In the present invention, the “horizontal shape” of the horizontal posture of the seat portion 9 refers to a range in which the reference seating surface 9e is not less than 0 degrees and not more than 15 degrees with respect to the horizontal plane.
Further, the “vertical surface shape” of the vertical posture of the seat portion 9 refers to a range in which the reference seat surface 9e is 70 degrees or more and 100 degrees or less with respect to the horizontal plane.

  Further, when the caregiver rotates the seat portion 9 backward from the maximum retracted position, the elevating tube portion 91a is rotated around the vertical axis Lz, and the guide roller 96 is moved from the horizontal portion 95e of the cam groove 95. This corresponds to the lower side of the inclined portion 95f. Then, the rotating member 91 swings around the vertical axis Lz while descending along the inclined portion 95f by its own weight. As the rotating member 91 is lowered, the seat portion 9 automatically assumes a horizontal plane posture. Further, when the guide roller 96 is disposed at the seat reference position, the guide roller 96 is inserted into the vertical portion 95g of the cam groove 95, and the rotation of the rotation member 91 is prevented.

  That is, the switching of the seat portion 9 from the standing posture to the horizontal surface posture does not apply a large operating force that causes the seat portion 9 to swing around the horizontal axis Ly, but allows the seat portion 9 to move to the vertical axis Lz. This can be done by using the operating force to rotate around.

  Further, as shown in FIGS. 3 to 7, a pair of left and right U-shaped hooking belt portions 20d illustrated by a two-dot chain line suspended (hanging) on the belt hooking portion 22d, and a hooking belt A sling member 20 having a pad portion 20e connected to the portion 20d and supporting the back of the weak body M (the waist or the vicinity of the scapula) is provided. Although not shown, in order to attach the pad portion 20e to the back of the weak body M, the distal end portion has one male and one first buckle member disposed on the left and right sides of the pad portion 20e. A first mounting belt portion; and a second mounting belt portion that is disposed on the left and right side and has a male and female second buckle member at a tip portion. The first buckle member and the second buckle member are detachably engaged (fitted) in the vicinity of the front abdomen of the weak body M so that the pad portion 20e can be attached.

  In addition, a floor lock mechanism 10 that can be operated with a foot pedal is provided at the front portion of the lower frame portion 81. By operating the foot pedal, the pressing member presses against the floor surface (wheel traveling surface) and travel by the wheel 80 is prevented.

  In addition, as a whole transfer vehicle, each part is manufactured by combining resin and stainless steel products and commercial products, rust-proof and waterproof processed products and commercial products, so that it has water resistance, It makes it possible to wash hair and take a shower with a weak person on board.

Next, the operation (usage method) of the transfer vehicle of the present invention will be described.
First, as shown in FIG. 3, it is arranged in front of a weak body M seated on the side edge of a bed or a wheelchair, etc., and the floor lock mechanism 10 is operated by a foot pedal so as to be locked. Stop. Further, the seat portion 9 is disposed at the maximum retracted position, although not shown.

  Then, the foot of the weak body M is placed on the foot placement surface 3d, and the knee portion or the vicinity of the knee is brought into contact with the bent concave portion 70 of the lower leg support member 7 at the lower leg portion of the weak body M. Further, the lower leg belt 27 is attached to the calf part at the lower leg part. Further, the weak body M is caused to grip the grip 51 and the forearm or elbow is brought into contact with the elbow rest 52. Further, the pad portion 20e of the sling member 20 is brought into contact with the back of the weak body M, and the first buckle member and the second buckle member (not shown) are detachably engaged (fitted) in the vicinity of the abdomen of the weak body M. Then, the pad portion 20e is attached. The pair of left and right hooking belt portions 20d are hung on the belt hooking portion 22d from the armpit or lateral abdomen side of the weak body M so as to be ready for lifting. In addition, the contact position of the pad part 20e is free in the vicinity of the scapula, the waist, the buttocks, and the like.

  Since the grip part 51 has an upward projecting shape, the weak body M can relax his / her elbow part against the elbow rest part 52 without twisting his wrist greatly, without taking an unreasonable posture (natural body). it can. Since the step member 3 has an upwardly inclined shape, the sole can be brought into close contact with the step member 3 without extending the ankle in a seated posture (without applying a load). The bent concave portion 70 swings around the upper connection axis Lk and adheres along the lower leg portion of the weak body M. The lower leg belt 27 prevents the weakly handicapped M's knee from separating from the curved concave portion 70. Since the belt hanging portion 22d has a hook portion, the U-shaped hooking belt portion 20d prevents the left and right outwards from coming off.

When a caregiver (not shown) operates the release lever 14 to release the expansion / contraction lock of the expansion / contraction member 50 and swings the handle portion 11 of the operation rod 1 forward and downward with the expansion / contraction lock released. As shown in FIG. 4, the rear end sides of the first and second rod-like bodies 21 and 22 swing forward and upward, and the telescopic member 50 extends. The belt hooking portion 22d of the second bowl 22 moves forward and upward, and the forearm receiving member 5 also moves forward and upward. By grasping the sling member 20 and the grip portion 51, the upper body of the weak body M is moved forward. It is drawn upwards and becomes a standing posture.
Furthermore, since the suspension interlocking rod 4 lowers the front end portion 3a of the step member 3 by the lowering of the front end side (extension portion 22c) of the second rod-shaped body 22, the weight (center of gravity) of the weak body M is moved forward. It becomes easy to move. Further, the curved concave portion (knee pad member) 70 always abuts (fits) the weak body M, thereby helping to raise the upper body with the knee as a fulcrum.

  Further, as the forearm receiving member 5 moves forward and upward by the deformed parallel link mechanism 2, the forward tilt angle α (of the elbow rest 52) gradually decreases, so that the center of gravity of the weak body M moves forward and downward. As a result, the weight is easily supported by the step member 3 and the forearm receiving member 5. Further, even if the weak body M does not grip the grip portion 51 with a strong force, the forearm portion and the elbow portion can be prevented from slipping down from the elbow rest portion 52. In addition, the weak body M can be prevented from slipping out of the pad portion 20e.

  Further, when the weak body M is lifted, the load of the weak body M applied to the step member 3 becomes a force to pull down the suspension interlocking rod 4. The force is a force that lifts the rear end side of the second bowl 22. That is, the load (weight) of the weak body M can be used as an operation force for lifting the weak body M, and the burden on the caregiver who operates the operation rod 1 is reduced as the load of the weak body M moves to the step member 3. Is done.

  When the care giver stops the operation of the release lever 14 in a state where the weak body M is standing, the expansion / contraction of the expansion / contraction member 50 is prevented and the swinging of the second rod-shaped body 22 is prevented. Therefore, even if the caregiver releases his hand from the operation rod 1, the standing posture of the weak body M is maintained. In this standing posture, the physically weak person M puts weight on the sling member 20 (from behind), so that his / her legs are not burdened and his / her posture is maintained. Then, it moves (runs) in this standing posture, or separates a bed, a wheelchair or the like to secure a space below the buttocks of the weak body M. Further, by stopping the operation of the release lever 14 in the middle of standing, it can be held in a desired posture (mid-standing posture) desired by the weak body M or the caregiver.

  Then, when the caregiver applies an operating force around the vertical axis Lz to the seat portion 9, the seat portion 9 switches from the maximum retracted position to the reference seat position, and as shown in FIG. Switch automatically. Then, when the caregiver operates the release lever 14 to allow the telescopic member 50 to expand and contract and swing the operating rod 1 upward and rearward, the telescopic member 50 is shortened, and the first and second rod-like bodies The rear end sides of 21 and 22 are lowered, and the forearm receiving member 5 is also moved rearward and downward, and as shown in FIG.

Then, after the weak person M is seated, the operation of the release lever 14 is stopped (brake is released), the lock of the floor lock mechanism 10 is released, the operation rod 1 is gripped and pulled, and the vehicle is driven by the wheels 80. Thus, the physically weak person M can be moved in the seated state (posture).
When the physically weak person M gets off (get-off work), the reverse procedure of the above-mentioned getting-on work may be performed (FIGS. 6, 5, 4 and 3 may be performed sequentially), and the transfer from the bed to the wheelchair is possible. It is also possible to transfer from bed to bed.

It is provided so as to be switchable to an upright posture (FIGS. 1 and 8 to 9) swinging upward. 7 to 10, the cushion part forming the reference seating surface 9 e of the seat part 9 and the lower frame part supporting the cushion part are shown by two-dot chain lines, and in FIGS. 2 to 4, The illustration is omitted.

  As shown in FIGS. 5 to 7, the seat portion 9 is disposed below the buttocks (butt portion) of the weak body M who has boarded, and a reference seat position where the weak body M can sit on the seat portion 9 and FIG. As shown in FIGS. 8 to 9, the seat portion is rotated from the reference seat position toward the left and right sides so as not to interfere with the getting on and off of the weak body M, and is disposed on the left and right sides. It is provided so as to switch to the retreat position. The seat 9 is disposed outside the scheduled movement range of the weak body M at the seat retreat position. The reference seat position is a position at which the base end edge portion of the seat portion 9 (also described below, the horizontal axis Ly, the cylindrical portion 90, and the support portion 91b) is disposed along the left-right direction.

  Then, as shown in FIGS. 7 to 10, the pivotable angle θz in plan view from the reference seat position to the maximum retracted position rotated about the vertical axis Lz is set to 180 degrees or more and 270 degrees or less. ing. More preferably, it is set to 240 degrees or more and 260 degrees or less. If it is less than the lower limit, there is a high possibility that the weak body M will come into contact with the bed or wheelchair on which the weak body M sits. In addition, if the upper limit is exceeded, it is necessary to prevent the seat 9 from coming into contact with other members such as the base 8 and the crus support member 7, so the distance between the base 8 and the seat 9 needs to be increased. , The whole becomes large (the whole cannot be made compact).

  The seat portion 9 is provided so as to be swingable around the horizontal axis Ly, and within the range from the reference seat position to the maximum retracted position, the seat portion 9 is upright from the horizontal plane posture to the base end downward inclination or the vertical plane shape. It is configured to get up in a posture. In other words, the posture is changed from the standing posture to the horizontal posture within the range from the maximum retracted position to the reference seat position.

The seat portion 9 has a cylindrical portion 90 disposed along the base end edge portion in the vicinity of the base end edge portion.
And the raising / lowering cylinder part 91a which is arrange | positioned by the cylindrical part 87 of the base 8, and is rotatable around the vertical axis Lz, and the cross-sectional circular shape which protrudes horizontally from the upper part of the raising / lowering cylinder part 91a And an L-shaped rotating member 91 having a supporting portion 91b.
The cylindrical portion 90 of the seat portion 9 is disposed on the support portion 91b of the rotating member 91 so as to be fitted outside, and the seat portion 9 is rotatable and supported around the vertical axis Lz of the columnar portion 87. It can be swung around the horizontal axis Ly of the portion 91b.

Further, a cam groove (cylindrical groove cam type guide hole) 95 is provided through the cylindrical wall portion of the elevating cylinder portion 91a of the rotating member 91.
Further, a guide roller 96 made of a bearing inserted into the cam groove 95 is projected from the columnar portion 87.
As shown in FIG. 7, the cam groove 95 has an upper edge 95c that contacts the guide roller 96 at the reference seat position of the seat 9, and a lower edge that contacts the guide roller 96 at the maximum retracted position as shown in FIG. 95d.
Further, the cam groove 95 has a vertically short vertical portion 95g having an upper end edge portion 95c as shown in FIG. 7, and a circumferential horizontal portion 95e having a lower end edge portion 95d as shown in FIG. As shown in FIG. 7 to FIG. 9, it has an inclined portion 95f in the vertical spiral direction connecting the vertical portion 95g and the horizontal portion 95e.

  That is, when the elevating tube 91a rotates around the vertical axis Lz while the inner edge (inner surface) of the cam groove 95 is in sliding contact with the guide roller 96, the vertical pitch dimension (edge) of the upper edge 95c and the lower edge 95d. The elevating cylinder portion 91a (the rotation member 91) is configured to move up and down with a center point vertical separation dimension.

Further, an outer cylinder member 93 is provided on the elevating cylinder portion 91a so as to be fitted around and is rotatable around the vertical axis Lz.
The outer cylinder member 93 includes an upper cylinder part 93c, a lower cylinder part 93d, and a connecting part 93g that connects the upper cylinder part 93c and the lower cylinder part 93d with a predetermined separation dimension. And between the upper cylinder part 93c and the lower cylinder part 93d, the guide roller 96 is arrange | positioned in insertion shape, and the horizontal opening-shaped window part (slit part) 93k which makes one round along the circumferential direction is formed. Yes.
The guide roller 96 prevents the outer cylinder member 93 from moving up and down and can rotate about the vertical axis Lz while being held at a predetermined height position.

  Then, the upper end side (one end side) is pivotally attached to the seat portion side projecting piece portion 90v projecting from the seat portion 9 (the cylindrical portion 90 thereof) with a horizontal seat portion side connecting axis L9, and the outer cylinder. The interlocking connecting member 92 is pivotally attached to the base side protruding piece 93v protruding from the member 93 with the base side connecting axis L8 parallel to the seat side connecting axis L9 at the lower end side (the other end side). It has.

As shown in FIG. 7, when the seat portion 9 is in the reference seat position and in a horizontal plane posture, the guide roller 96 corresponds to the vertical portion 95g of the cam groove 95, and the rotation member 91 is prevented from rotating. Yes.
When the caregiver grips and lifts the tip edge 9b side of the seat 9, the rotating member 91 is also lifted, and the guide roller 96 corresponds to the upper part of the inclined portion 95f. The portion 9 can be rotated from the reference seat position toward the rear side and the left and right outer sides.

When the seat 9 is rotated about the vertical axis Lz by the caregiver, the rotating member 91 is also rotated about the vertical axis Lz, and the guide roller 96 corresponds to the inclined portion 95f of the cam groove 95. Then, as the cam groove 95 extends along the guide roller 96, the rotating member 91 rises as shown in FIG. When the rotation rises, the rotating member 91 rises, but the outer cylinder member 93 (base-side protruding piece portion 93v) rotates while maintaining a predetermined height position. The side projection piece 90v is pulled downward, the cylindrical portion 90 rotates around the horizontal axis Ly, and the seat portion 9 swings upward from the horizontal plane posture to tilt downward at the proximal end (tilt upward at the distal end). As a result, the vertical posture becomes a standing posture.
That is, the caregiver can change the seat portion 9 to the upright posture by the action of the cam groove 95 (with a small force) without swinging the tip edge portion 9b side of the seat portion 9 upward with a large force.

As shown in FIG. 9, when the horizontal portion 95e of the cam groove 95 corresponds to the guide roller 96, the rotating member 91 does not move up and down even if it rotates about the vertical axis Lz, and the seat portion 9 Is held in an upright posture by the outer cylinder member 93 while the base end edge portion (seat portion side protruding piece portion 90v) of the seat portion 9 is drawn downward.
When the guide roller 96 comes into contact with the lower end edge portion 95d of the cam groove 95, the rotation of the rotating member 91 exceeding the rotation possible angle θz is restricted, and the seat portion 9 is arranged at a predetermined maximum retracted position. Established.

Here, in FIGS. 8 to 10, when the seat 9 (cylindrical portion 90 and support portion 91b) is rotated approximately 180 degrees around the vertical axis Lz from the reference seat position, the guide roller 96 is horizontal from the inclined portion 95f. The seat portion 9 is in a standing posture in a vertical plane corresponding to the shape portion 95e, and after exceeding about 180 degrees, the standing posture of the seat portion 9 is not changed (the vertical plane shape is kept). It is configured to rotate to a position.
Although not shown in the drawings, the cam groove 95 may be provided so that when the seat portion 9 is rotated approximately 90 degrees around the vertical axis Lz, a vertical plane-like standing posture is obtained. Or you may provide so that it may become a vertical planar standing posture in the maximum retracted position.
That is, if the seat 9 is switched from the horizontal plane posture to the upright posture between the reference seat position and the maximum retracted position, the swing timing of the posture of the seat portion 9 and the timing of the end of the swing (the start start time) The moving angle and the standing end turning angle are free.

In the present invention, the “horizontal shape” of the horizontal posture of the seat portion 9 refers to a range in which the reference seating surface 9e is not less than 0 degrees and not more than 15 degrees with respect to the horizontal plane.
Further, the “vertical surface shape” of the vertical posture of the seat portion 9 refers to a range in which the reference seat surface 9e is 70 degrees or more and 100 degrees or less with respect to the horizontal plane.

  Further, when the caregiver rotates the seat portion 9 backward from the maximum retracted position, the elevating tube portion 91a is rotated around the vertical axis Lz, and the guide roller 96 is moved from the horizontal portion 95e of the cam groove 95. This corresponds to the lower side of the inclined portion 95f. Then, the rotating member 91 swings around the vertical axis Lz while descending along the inclined portion 95f by its own weight. As the rotating member 91 is lowered, the seat portion 9 automatically assumes a horizontal plane posture. Further, when the guide roller 96 is disposed at the seat reference position, the guide roller 96 is inserted into the vertical portion 95g of the cam groove 95, and the rotation of the rotation member 91 is prevented.

  That is, the switching of the seat portion 9 from the standing posture to the horizontal surface posture does not apply a large operating force that causes the seat portion 9 to swing around the horizontal axis Ly, but allows the seat portion 9 to move to the vertical axis Lz. This can be done by using the operating force to rotate around.

  Further, as shown in FIGS. 3 to 7, a pair of left and right U-shaped hooking belt portions 20d illustrated by a two-dot chain line suspended (hanging) on the belt hooking portion 22d, and a hooking belt A sling member 20 having a pad portion 20e connected to the portion 20d and supporting the back of the weak body M (the waist or the vicinity of the scapula) is provided. Although not shown, in order to attach the pad portion 20e to the back of the weak body M, the distal end portion has one male and one first buckle member disposed on the left and right sides of the pad portion 20e. A first mounting belt portion; and a second mounting belt portion that is disposed on the left and right side and has a male and female second buckle member at a tip portion. The first buckle member and the second buckle member are detachably engaged (fitted) in the vicinity of the front abdomen of the weak body M so that the pad portion 20e can be attached.

  In addition, a floor lock mechanism 10 that can be operated with a foot pedal is provided at the front portion of the lower frame portion 81. By operating the foot pedal, the pressing member presses against the floor surface (wheel traveling surface) and travel by the wheel 80 is prevented.

  In addition, as a whole transfer vehicle, each part is manufactured by combining resin and stainless steel products and commercial products, rust-proof and waterproof processed products and commercial products, so that it has water resistance, It makes it possible to wash hair and take a shower with a weak person on board.

Next, the operation (usage method) of the transfer vehicle of the present invention will be described.
First, as shown in FIG. 3, it is arranged in front of a weak body M seated on the side edge of a bed or a wheelchair, etc., and the floor lock mechanism 10 is operated by a foot pedal so as to be locked. Stop. Further, the seat portion 9 is disposed at the maximum retracted position, although not shown.

  Then, the foot of the weak body M is placed on the foot placement surface 3d, and the knee portion or the vicinity of the knee is brought into contact with the bent concave portion 70 of the lower leg support member 7 at the lower leg portion of the weak body M. Further, the lower leg belt 27 is attached to the calf part at the lower leg part. Further, the weak body M is caused to grip the grip 51 and the forearm or elbow is brought into contact with the elbow rest 52. Further, the pad portion 20e of the sling member 20 is brought into contact with the back of the weak body M, and the first buckle member and the second buckle member (not shown) are detachably engaged (fitted) in the vicinity of the abdomen of the weak body M. Then, the pad portion 20e is attached. The pair of left and right hooking belt portions 20d are hung on the belt hooking portion 22d from the armpit or lateral abdomen side of the weak body M so as to be ready for lifting. In addition, the contact position of the pad part 20e is free in the vicinity of the scapula, the waist, the buttocks, and the like.

  Since the grip part 51 has an upward projecting shape, the weak body M can relax his / her elbow part against the elbow rest part 52 without twisting his wrist greatly, without taking an unreasonable posture (natural body). it can. Since the step member 3 has an upwardly inclined shape, the sole can be brought into close contact with the step member 3 without extending the ankle in a seated posture (without applying a load). The bent concave portion 70 swings around the upper connection axis Lk and adheres along the lower leg portion of the weak body M. The lower leg belt 27 prevents the weakly handicapped M's knee from separating from the curved concave portion 70. Since the belt hanging portion 22d has a hook portion, the U-shaped hooking belt portion 20d prevents the left and right outwards from coming off.

When a caregiver (not shown) operates the release lever 14 to release the expansion / contraction lock of the expansion / contraction member 50 and swings the handle portion 11 of the operation rod 1 forward and downward with the expansion / contraction lock released. As shown in FIG. 4, the rear end sides of the first and second rod-like bodies 21 and 22 swing forward and upward, and the telescopic member 50 extends. The belt hooking portion 22d of the second bowl 22 moves forward and upward, and the forearm receiving member 5 also moves forward and upward. By grasping the sling member 20 and the grip portion 51, the upper body of the weak body M is moved forward. It is drawn upwards and becomes a standing posture.
Furthermore, since the suspension interlocking rod 4 lowers the front end portion 3a of the step member 3 by the lowering of the front end side (extension portion 22c) of the second rod-shaped body 22, the weight (center of gravity) of the weak body M is moved forward. It becomes easy to move. Further, the curved concave portion (knee pad member) 70 always abuts (fits) the weak body M, thereby helping to raise the upper body with the knee as a fulcrum.

  Further, as the forearm receiving member 5 moves forward and upward by the deformed parallel link mechanism 2, the forward tilt angle α (of the elbow rest 52) gradually decreases, so that the center of gravity of the weak body M moves forward and downward. As a result, the weight is easily supported by the step member 3 and the forearm receiving member 5. Further, even if the weak body M does not grip the grip portion 51 with a strong force, the forearm portion and the elbow portion can be prevented from slipping down from the elbow rest portion 52. In addition, the weak body M can be prevented from slipping out of the pad portion 20e.

  Further, when the weak body M is lifted, the load of the weak body M applied to the step member 3 becomes a force to pull down the suspension interlocking rod 4. The force is a force that lifts the rear end side of the second bowl 22. That is, the load (weight) of the weak body M can be used as an operation force for lifting the weak body M, and the burden on the caregiver who operates the operation rod 1 is reduced as the load of the weak body M moves to the step member 3. Is done.

  When the care giver stops the operation of the release lever 14 in a state where the weak body M is standing, the expansion / contraction of the expansion / contraction member 50 is prevented and the swinging of the second rod-shaped body 22 is prevented. Therefore, even if the caregiver releases his hand from the operation rod 1, the standing posture of the weak body M is maintained. In this standing posture, the physically weak person M puts weight on the sling member 20 (from behind), so that his / her legs are not burdened and his / her posture is maintained. Then, it moves (runs) in this standing posture, or separates a bed, a wheelchair or the like to secure a space below the buttocks of the weak body M. Further, by stopping the operation of the release lever 14 in the middle of standing, it can be held in a desired posture (mid-standing posture) desired by the weak body M or the caregiver.

  Then, when the caregiver applies an operating force around the vertical axis Lz to the seat portion 9, the seat portion 9 switches from the maximum retracted position to the reference seat position, and as shown in FIG. Switch automatically. Then, when the caregiver operates the release lever 14 to allow the telescopic member 50 to expand and contract and swing the operating rod 1 upward and rearward, the telescopic member 50 is shortened, and the first and second rod-like bodies The rear end sides of 21 and 22 are lowered, and the forearm receiving member 5 is also moved rearward and downward, and as shown in FIG.

Then, after the weak person M is seated, the operation of the release lever 14 is stopped (brake is released), the lock of the floor lock mechanism 10 is released, the operation rod 1 is gripped and pulled, and the vehicle is driven by the wheels 80. Thus, the physically weak person M can be moved in the seated state (posture).
When the physically weak person M gets off (get-off work), the reverse procedure of the above-mentioned getting-on work may be performed (FIGS. 6, 5, 4 and 3 may be performed sequentially), and the transfer from the bed to the wheelchair is possible. It is also possible to transfer from bed to bed.

In FIG. 2, the second rod-like body 22 connects the pair of left and right arm rods pivotally attached to the base 8 and the rear ends of the pair of arm rods in the left-right direction. A first member 61 is provided that includes a connecting rod material that is fixed by welding and has belt hook portions 22d and 22d at both ends.
Further, the second bowl-shaped body 22 includes a second member 62 integrally having the attachment piece portions 22v, 22w, and 22x. Then, a bolt member 63 with a handle is rotatably held by the second member 62 and screwed into a screw hole provided in the first member 61 so that the second member 62 is screwed to the first member 61. Fixed (fixed).
Further, the second member 62 is pivotally attached to the first member 61 with a left and right horizontal pivot shaft 64 between the pivot portion with the connecting member 6 and the pivot portion with the telescopic member 50. Yes. In a state where the first member 61 and the second member 62 are fixed by the bolt member 63, the swinging of the second member 62 is prevented.
In this way, the first member 61 and the second member 62 are integrated with a screwed structure in a use state in which the weak body M is in a standing posture or a seated posture, and storage, transportation, packing, etc. When the bolt member 63 is screwed out in a non-use state, the second member 62 can swing around the pivot shaft (the pivot shaft 64) that is horizontally horizontal with respect to the first member 61, and the release lever 14 It is possible to tilt the operating rod 1 backward while keeping the telescopic member 50 in a shortened state without releasing the telescopic lock by gripping. The entire height dimension can be reduced (the whole can be made compact) for storage and transportation.

  In the present invention, the design can be changed, and the elastic member 50 only needs to be able to lock / unlock the swinging of the deformable parallel link mechanism 2, and the upper end of the elastic member 50 is the operation rod 1 or the first rod-shaped body 21 or the forearm You may provide so that the receiving member 5 may be pivotally attached.
