Description

  The present invention relates to an electric transfer device according to transfer assistance technology.

  With the advent of an aging society, the role of welfare equipment for elderly care is increasing. Among them, for example, in an operation (transfer) in which an elderly person (including a disabled person) or a patient who has difficulty walking, such as a patient, transfers from a bed to a wheelchair (transfer), the transfer depends on the height of the bed and the wheelchair seating surface. There is a problem that it becomes difficult. When this is transferred manually, a large burden is placed on the assisting side, which may cause problems such as back pain.

Moreover, the nursing care lift apparatus 51 shown in FIG. 7 is conventionally proposed as an apparatus used in such a case (refer patent document 1). However, this device 51 suspends the transferer E from above by a crane mechanism including a vertical support column 52, a horizontal arm 53, a suspension arm 54, etc., and is extremely large as a device, and has the following disadvantages. .
(1) Since the apparatus is large, it takes a space, and since a large apparatus is generally heavy, handling is not good.
(2) Since the device itself does not move, transfer work can be performed only in the vicinity of the device. Therefore, it cannot be transferred to a far destination.
(3) Prior to suspending the transferer E, it is necessary to place the transferor E on the transfer device 55 such as a bag (laying the transfer device 55 under the body of the transferor E), and the preparation work is troublesome. Take it.

  The present invention has been made in view of the above points, and it is an object of the present invention to provide a transfer device according to transfer assistance technology, which is relatively small and can be transferred to a remote transfer destination, and in which transfer work is simple. To do.

In order to achieve the above object, an electric transfer device according to claim 1 of the present invention includes a cart portion with casters, a drive source mounted on the cart portion, and a seat plate portion that is operated by the drive source. ,
The cart has a horizontal frame in which the rear ends of a pair of left and right side frames extending in the front-rear direction are connected by a rear end frame extending in the width direction, and the pair of left and right side frames are not parallel to each other and have a width between the front ends. The dimension is set larger than the width dimension between the rear edges,
A fixed frame is erected on the horizontal frame, a first actuator which is a vertical movement drive source is fixed to the fixed frame, a moving frame is connected to a driving rod end of the first actuator, and the moving frame is moved back and forth. A second actuator, which is a drive source, is fixed, the seat plate portion is coupled to a drive rod end of the second actuator, and the seat plate portion is positioned below the second actuator and the seat plate portion from below. A supporting frame to be supported is fixed to the moving frame, and a passenger protection frame positioned above the second actuator and the seat plate portion is fixed to the moving frame,
When the first actuator is driven, the moving frame moves up and down, and accordingly, the second actuator, the seat plate portion, the support frame, and the protective frame move up and down at the same time. When the second actuator is driven, the seat moves. The plate part is moved back and forth independently, and the seat plate part is moved forward by inserting the seat plate part from the crotch to the lower part of the buttocks with respect to the seated transfer person by driving the first and second actuators. A lifting operation for lifting the transferer from the inserted state in a state of being placed on the seat plate portion, a lowering operation for lowering the transferer from the lifted state, and the seat plate portion from below the transferer in the lowered state The reverse operation to pull out the
During the transfer operation, a contact type sensor is installed on the lower surface of the seat plate portion so that an assistant who operates the transfer device knows that the lower surface of the seat plate portion has contacted the seat surface of the transfer destination or the transfer source. ,
A contact-type sensor is attached to the tip of the support frame so that an assistant who operates the transfer device knows that the tip of the support frame is in contact with the transfer destination or the side of the transfer source during movement. It is characterized by that.

  The electric transfer device according to claim 2 of the present invention is the electric transfer device according to claim 1, wherein the seat plate portion includes a connection portion connected to the drive source, and an advance of the connection portion. It has an insertion part provided in the same plane on the front end side in the direction, and the insertion part is formed gradually thin toward the tip so that the insertion part can be easily inserted below the transferer, And the insertion part is formed in the shape where the width direction center part of the upper surface was dented rather than the both-sides part so that the said transferer's sitting might be good.

  The transfer device of the present invention having the above-described configuration performs transfer by sitting on a seat board portion in a posture that does not suspend a transfer person as in the prior art. In addition, it is assumed that the transferee cannot move up from the posture sitting on the edge of the bed or a wheelchair, and moves on the seat plate portion. The seat plate is moved by a drive source such as an electric actuator and operates as follows.

(1) Forward operation As the initial position of the transfer operation, the seat plate part is directly opposed to the front face of the seated passenger, and the height position is the height of the seat on which the seater is seated. Adjust to position. And from this initial position, the seat plate part moves forward toward the transferee, passes through the crotch of the transferee, and is inserted below the buttocks. The seat plate portion is inserted below the seated transferer, and is inserted between the seated seater and the seating surface on which the seater is seated. The transferee sits in a sitting position and slightly opens both feet to the left and right, and waits for the seat plate portion to be inserted.
(2) Lifting operation With the seat plate portion inserted below the transferee, the seat plate portion rises and lifts the transferee. The transferee is lifted while sitting in a posture straddling the seat plate.
(3) Descent operation After moving to the transfer destination, the seat plate part moves down and lowers the transferee to the transfer destination. In addition, the movement from the original position of the transfer to the transfer destination causes the entire transferer to change direction or travel by pushing or pulling the cart portion with casters. For example, transfer is to transfer a person from a bed to a wheelchair or vice versa, but not limited to this, for example, a general chair or sofa may be used as the original position or destination of transfer. The original position and the transfer destination may be any positions where the transferee is seated at the start and end of the transfer operation.
(4) Backward movement With the transferee lowered, the seat plate part moves backward and is pulled out from below the transferee. The transferee is released from the transferer while sitting at the transfer destination.

  As for the operation system of the seat plate portion that operates as described above, an operation portion (for example, a wired or wireless remote control box) operated by an assistant is prepared, and the seat plate portion is advanced, raised, and lowered in this operation portion. A switch (for example, four push button switches) for instructing the backward movement is set. For example, when the assistant presses the forward instruction button, the seat plate portion moves forward at a constant speed while pressing, and stops when the button is released. Since the height of the seating surface varies depending on the transfer position, such as a bed or a wheelchair, the operation unit is also used to adjust the initial movement position of the transfer operation.

  With the above forward operation, the seat plate part is inserted into the seated position from the crotch to the lower part of the buttocks. Sliding resistance with (for example, bed sheets) contributes to hindering insertion. Therefore, it is preferable for the transferee to have the upper body bend forward as much as possible, but to lift the buttocks, but it is necessary to devise the shape of the seat plate so that it can be easily inserted. Therefore, in the present invention, the insertion portion of the seat plate portion is gradually formed in a thin shape toward the tip, thereby making it easy to insert the insertion portion between the transfer person and the seat surface.

  Further, since the seat plate portion is inserted into the seated portion of the seated person from the crotch to the lower portion of the buttocks, the width size of the seat plate portion is set smaller than the width size of the person. Therefore, it is necessary to devise the shape of the seat plate portion so that the seat of the transferee is better. Therefore, in the present invention, the insertion portion of the seat plate portion is formed in a shape in which the central portion in the width direction of the upper surface is recessed from both side portions thereof, so that the transferer sits in a posture straddling the seat plate portion. The shape is easy to balance in the width direction of the seat plate. If the center in the width direction of the upper surface of the insertion part is recessed from both sides, the meat of the buttock of the transferer will approach the recess in the center of the width direction from both sides when the transferor sits in a posture that straddles this. Therefore, it becomes easier to balance the seat plate portion in the width direction. On the other hand, if the center in the width direction of the upper surface of the insertion part protrudes upward from both sides, the seat plate will have a bowl shape. The position shifts to the left or right in the seat plate width direction and falls down.

  As the material of the seat plate portion, it is desirable that the material has a low frictional resistance and is not easily broken even when a load (such as the weight of a transferee) is applied. For example, ultrahigh molecular weight polyethylene, neurite material, etc. Is preferred.

  The present invention has the following effects.

(1) In the above prior art, in order to suspend the transferer, the apparatus needs to be larger than the transferer in a seated posture. On the other hand, in the present invention, since the transferee is seated in a posture straddling the seat plate portion, the apparatus may be smaller than the transferee in a sitting posture. Small devices are lightweight and easy to handle.
(2) Since the assistant can change the direction of the transferer or run by pushing or pulling the cart portion with casters, the transferer can be transferred to a distant destination.
(3) If the transferer takes a sitting posture, the transfer operation is started by the assistant without any other preparation. Accordingly, it is possible to eliminate the trouble of placing the transferer on the transfer device.

  Therefore, according to the present invention, it is possible to provide a transfer device that is relatively small and can be transferred to a far destination, and that can be easily transferred.

  In addition to this, by forming the insertion part of the seat plate part gradually thin toward the tip, the insertion part can be easily inserted, and the insertion part of the seat plate part is centered in the width direction of the upper surface. By forming the part in a shape that is recessed from both side parts, it is possible to easily balance the seat board part in the width direction when the transferee sits in a posture straddling the seat board part. Therefore, the transfer device of the present invention is excellent in workability and safety.

  Next, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a schematic perspective view of a transfer device 1 according to an embodiment of the present invention. When a main outer cover 2 is removed from the transfer device 1, the structure is a front view of FIG. 2 and a plan view of FIG. It looks like the figure. In addition, the top view of FIG. 3 has shown the plane of only the site | part below the seat-plate part 31 instead of the whole apparatus. In the following description, the direction of the arrow X in FIGS. 2 and 3 is referred to as the forward direction, the front direction, or the front end direction, and the opposite direction is referred to as the backward direction, the back direction, or the rear end direction.

  First, the transfer device 1 according to this embodiment includes a cart unit 11 to which casters 16 are attached. The cart unit 11 is mounted with operating units such as drive sources 21 and 23 and a seat plate unit 31.

  The carriage unit 11 has a horizontal frame 12 having a substantially U-shaped plane in which the rear ends of a pair of left and right side frames 13 extending in the front-rear direction are connected by a rear end frame 14 extending in the width direction. A fixed frame 15 is erected vertically. The pair of left and right side frames 13 are not parallel to each other, and the width dimension between the front ends is set larger than the width dimension between the rear ends as shown in FIG. The casters 16 are attached to the front end and the rear end of the pair of left and right side frames 13, respectively, for convenience. For safety, a caster 16 with a brake mechanism is used, and a mechanism that can turn on / off the brakes of all four casters with a one-touch operation is used. Each of the casters 16 is of a vertical axis type that can change the direction of the carriage unit 11. A handle portion 17 is attached to the upper end portion of the fixed frame 15 so that the assistant moves (changes direction and travels) the transfer device 1.

  A movable frame 18 that is movable in the vertical direction is disposed on the front side of the fixed frame 15 that is erected on the horizontal frame 12, and the movable frame 18 is a vertical motion drive source that is fixed to the fixed frame 15. 1 It is connected to the drive rod end of the electric actuator 21. Further, an LM guide (linear motion guide) 22 that guides the vertical movement of the moving frame 18 with high accuracy is assembled between the fixed frame 15 and the moving frame 18, and when the first actuator 21 is driven as described above, The moving frame 18 moves up and down.

  A second electric actuator 23, which is a forward / backward drive source, is fixed to the moving frame 18 with the drive rod 23a facing in the front direction, and a seat plate portion 31 is connected to the tip of the drive rod 23a. The seat plate portion 31 will be described later. A support frame 24 with an LM guide that is positioned below the second actuator 23 and the seat plate portion 31 and supports the seat plate portion 31 from below is fixed to the moving frame 18, and the second actuator 23 and the seat plate portion 31. A transferer protection frame 25 having a pair of left and right grips 26 gripped by the transferer is fixed to the moving frame 18. The pair of left and right grips 26 are optional parts and may be omitted. In this case, the transferee directly holds the protective frame 25 instead of the grips 26. Similarly to the horizontal frame 12, the protective frame 25 is provided with a portion having a substantially U-shaped plane and surrounds the transferer during transfer, so that the transferer can lean on it. A safety belt 27 for preventing the transfer person from falling in the back direction is detachably attached to the section. As a mounting position of the safety belt 27, a pair of left and right belt mounting portions 29 having a projecting upward shape are provided at the rear end portion of the seat plate portion 31, and both end portions of the safety belt 27 can be attached to and detached from the belt mounting portion 29. In any case, the safety belt 27 is looped to the back side of the transfer person sitting on the seat plate portion 31.

  When the first actuator 21 is driven as described above, the moving frame 18 moves up and down accordingly, and the second actuator 23, the seat plate portion 31, the support frame 24, and the protective frame 25 move up and down at the same time. When the second actuator 23 is driven, the seat plate portion 31 moves back and forth independently.

  In addition, a pair of left and right footrests 28 on which a transferee rests his / her soles are provided inside the horizontal frame 12 that is substantially U-shaped in a plane. Further, the transfer device 1 is equipped with a battery power source (not shown) for driving the electric actuators 21 and 23. The transfer device 1 is provided with a remote control type control unit (not shown) for controlling the driving of the actuators 21 and 23. The control unit is provided with four push button switches, and controls the driving of the actuators 21 and 23 as follows.

When the first switch is pressed, the second actuator 23 is driven and the drive rod 23a of the second actuator 23 extends in the front direction. Accordingly, along with this, the seat plate portion 31 moves forward.
When the second switch is pressed, the first actuator 21 is driven while the switch is being pressed, and the drive rod of the first actuator 21 extends upward. Accordingly, along with this, the seat plate portion 31 is raised.
When the third switch is pressed, the first actuator 21 is driven while the switch is being pressed, and the drive rod of the first actuator 21 is contracted. Accordingly, along with this, the seat plate portion 31 is lowered.
When the fourth switch is pressed, the second actuator 23 is driven while the switch is being pressed, and the drive rod 23a of the second actuator 23 is retracted. Accordingly, along with this, the seat plate portion 31 moves backward.

  Next, details of the seat plate portion 31 will be described with reference to FIG. As described above, the seat plate portion 31 is inserted into the lower part of the transferee in a posture sitting on the edge of the bed and is configured as follows.

That is, the seat plate portion 31 includes a connecting portion 32 having a predetermined length L ₁ (about 230 mm (the dimensional numerical value indicates the actual size value, the same applies hereinafter)) connected to the tip of the drive rod 23a of the second actuator 23. And an insertion portion 33 having a predetermined length L ₂ (about 290 mm) provided in the same plane on the front end side in the forward direction of the connecting portion 32 and made of ultrahigh molecular weight polyethylene (Newlite material). It is formed into a single plate. The seat plate portion 31 has the following features as its shape and structure.

(A) As shown in FIG. 6B, the insertion portion 33 is gradually formed thin toward the tip 33a so that the insertion portion 33 can be easily inserted below the transferee. Constant where the thickness T ₁ of about 35mm of the connecting portion 32 as shown in the figure, the first inclined surface 34 of the downward angle of about 14 degrees on the distal end side of the connecting portion 32, the descending angle of about 2.4 degrees The second inclined surface portion 35 and the third inclined surface portion 36 having a descending angle of about 11.2 degrees are sequentially provided, and the thickness T ₂ of the insertion portion 33 is approximately equal to the boundary portion between the second inclined surface portion 35 and the third inclined surface portion 36. It is set to 20 mm. The tip 33a of the insertion portion 33 is rounded by about R5 mm so that bed sheets and the like are not caught. The lower surface of the seat plate portion 31 is formed in a flat surface shape.

(B) As shown in FIG. 6 (A), the tip 33a of the insertion portion 33 is formed in a flat semicircular shape or an arc shape so that the insertion portion 33 can be easily inserted below the transferee. Since the width W ₂ of the insertion portion 33 is about 145mm, the radius of the semi-circular or arcuate is set to half.

(C) As shown in FIG. 6 (D), the insertion portion 33 is formed in a shape in which the center portion 33b in the width direction of the upper surface is recessed from the both side portions 33c so that the passenger can sit well. The dent shape is formed with a circular arc-shaped cross section (R400 to 450 mm), and the dent amount (depth) is about 4 mm at the maximum. The concave shape is formed in a groove shape extending along the longitudinal direction of the insertion portion 33.

(D) In order to improve the sitting of the transfer person, it is desirable that the width of the insertion portion 33 is as large as possible. However, the width of the connecting portion 32 is the same as the width of the insertion portion 33. When set, for the transferee, the inner crotch easily hits the side surface of the connecting portion 32 while sitting on the insertion portion 33, and the transferee is likely to be uncomfortable. Therefore, as shown in FIG. 6A, the width W ₁ (about 120 mm) of the connecting portion 32 is set to be relatively small (narrow) with respect to the width W ₂ (about 145 mm) of the insertion portion 33.

(E) If the assistant who operates the transfer device 1 can quickly and accurately know that the lower surface of the insertion portion 33 in the seat plate portion 31 is in contact with the transfer destination or the seat surface of the transfer source during the transfer operation. As a result, the safety of the transfer is ensured and the operation / work becomes easier. Therefore, as shown in FIG. 6A, the sensor 41 is assembled to the lower surface of the insertion portion 33 in the seat plate portion 31, and when the sensor 41 comes into contact with the seat surface, this is notified to the assistant. As the sensor 41, a thin contact type sensor is suitable, and the sensor surface (sensor switch) is disposed downward. When the sensor 41 is away from the seating surface, the contact surface pressure is zero, and the sensor circuit is cut off at this time. When the sensor 41 comes into contact with the seating surface, contact surface pressure is generated, the sensor circuit is passed, and a sensor signal is generated. As a means for informing based on the signal, for example, a required number (four in the figure) of light emitting LEDs (for example, green) is embedded in the connecting portion 32 of the seat plate portion 31, and a sensor signal is generated. In the meantime, the LED 42 emits light so that the assistant can view it from above. Thereby, the assistant can confirm that there is no height difference between the seat surface and the seat plate portion 31.

  In order to ensure this safety, as shown in FIG. 2 and the like, a sensor 43 is also assembled at the tip of the support frame 24, and the sensor 43 is mounted on the side surface (vertical surface portion) of the transfer destination or transfer source. When contacted, inform the caregiver of that. As the sensor 43, a thin contact type sensor is suitable, and the sensor surface (sensor switch) is installed in the front direction. When the sensor 43 is away from the side surface, the contact surface pressure is zero, and at this time, the sensor circuit is cut off. When the sensor 43 comes into contact with the side surface, a contact surface pressure is generated, the sensor circuit is transmitted, and a sensor signal is generated. As means for informing based on the signal, for example, as shown in FIG. 6 (A), a required number (two in the figure) of light emitting LEDs (e.g., red) as the light emitting color at the connecting portion 32 in the seat plate portion 31. When the sensor signal is emitted, the LED 44 emits light during this period, and the assistant can visually recognize it from above. Thereby, the assistant can confirm that there is no gap in the horizontal direction between the transfer destination or the side surface of the transfer source and the transfer device 1.

(F) As described above, the seat plate portion 31 is formed of a resin-based material such as ultrahigh molecular weight polyethylene. However, in order to support the weight of one person (for example, assuming a maximum of 120 kg), the strength is insufficient. Concerned. Therefore, as shown in FIGS. 6C and 6D, a recessed portion 39 for installing a reinforcing material is provided on the lower surface of the seat plate portion 31, and a reinforcing material (not shown) made of an iron plate or the like is assembled thereto. ing. Further, when the reinforcing material is assembled in this way, the drive rod 23a of the actuator 23 and the seat plate portion 31 may be coupled via the reinforcing material. As shown in FIG. 6A, the connecting portion 32 is provided with a notch 40 for assembling the connecting portion 32 to the drive rod 23a so as to open to the upper and lower surfaces and the rear end surface.

  Next, a transfer operation using the transfer device 1 will be described. Assuming that the transferor is transferred from the bed to the wheelchair.

  The transfer person sits with his legs slightly open at the edge of the bed, and the assistant brings the transfer device 1 and faces the front of the transfer person. The seat plate portion 31 is in the retracted position shown in FIGS. 2 and 3 as its initial movement position, and the assistant positions the tip of the support frame 24 against the side surface of the bed (at this time, the sensor 43 can confirm the position) As described above, the adjustment of the initial movement position is completed by matching the height position of the seat plate portion 31 with the height position of the bed. Next, the assistant operates the transfer device 1 so that the transfer device 1 operates in the following procedure.

(1) The seat plate portion 31 moves forward from the initial movement position of FIGS. 2 and 3 to the position of FIGS. 4 and 5, whereby the seat plate portion 31 passes through the crotch of the transferee E and is inserted below the buttocks. . If the transferer E takes the posture such that the upper body is bent forward and grips the protective frame 25 or the grip 26 with both hands and the buttocks float, the seat plate 31 is smoothly inserted. Since the forward stroke of the seat plate 31 is set to about 350 mm, the insertion is completed when the stroke limit is reached. The forward (and backward) speed of the seat plate portion 31 is preferably about 36 mm / second.
(2) The seat plate portion 31 rises and lifts the transfer person E. The transferer E is lifted while sitting in a posture straddling the seat plate portion 31. The ascending (and descending) speed of the seat plate portion 31 is preferably about 18 mm / second. Through this (1) and (2), the seat plate portion 31 moves forward and rises to lift the transferer E, so that it becomes an image of scooping up the transferer E as an operation.
(3) The seat plate portion 31 moves backward with the transferer E placed thereon, and is ready to move to the transfer destination.
(4) After moving to the transfer destination, the seat plate portion 31 moves forward with the transferer E placed thereon, and assumes a transfer posture to the transfer destination.
(5) The seat plate portion 31 is lowered, and the transferee E is lowered to the destination (at this time, the height position is confirmed by the sensor 41 as described above).
(6) The seat plate portion 31 is retracted and pulled out from below the transferee E. The transferer E is released from the transfer device 1 while sitting at the transfer destination.

  Therefore, according to the transfer device 1 of the embodiment of the present invention configured and operated as described above, a transfer device that can be transferred to a small distance and is easy to transfer as in the intended purpose of the present invention. Can be provided.
