JP 2011-10703 A JP 2007-7195 A JP 2008-279232 A Japanese Patent Publication No. 2-30260 JP 2006-305092 A

2. Description of the Related Art Conventionally, a need for a transfer operation in which a care recipient is transferred from a wheelchair to a bed or vice versa, often occurs in the course of daily life. However, it will be difficult to be independent until you get help from a helper whenever you need it. On the other hand, there is a problem that the burden on the caregiver, particularly the burden on the restraint time for assistance, the preparation time, etc. is large.
In addition, when a care recipient who needs assistance raises a spiritual feeling toward the caregiver, both of them become stressed and cause a mental state malfunction, or a situation in which only one dangerous person tries to stand up. I'm worried.
Therefore, in the past, development of a transfer assisting device or transfer assisting device that can be used safely and conveniently during a transfer operation in which a care recipient is transferred from a wheelchair to a bed or vice versa, for example, is transferred. Various types of transfer aids as shown in Patent Documents 1 to 5 have been proposed and put into practical use.

Incidentally, the transfer assisting machine proposed in the above-mentioned Patent Document 1 has a strut in front of the base portion, a knee pad provided on the column, an elbow pad provided on the upper end of the column, and further The configuration includes a gripping arm portion provided so as to protrude to the front side.
This transfer support machine is described as being small and easy to use because it can easily and quickly achieve the purpose of transferring care recipients.
The walking assist device proposed in Patent Document 2 includes walking casters at four corners of a base frame, and has a handle-shaped leaning portion at the upper end of a column that stands vertically to the base frame. It is described that since the portion is integrated with the armrest portion and the stable gripping member, the number of parts can be reduced and the manufacturing cost can be suppressed.
The transfer device disclosed in Patent Document 3 is a device for moving a person with a disability, and is provided with a support on a platform that can be moved by a caster, and a base of an operation arm (handle) attached to the support. A chest support is attached to the end, and a knee pad for the care recipient is provided at the bottom of the frame (support). The chest pad is tilted forward via a guide plate, and the knee pad is rearward via a guide rail. It is explained that the system can be linked and the transfer of the care recipient can be done with the minimum possible amount.

The patient hoist disclosed in Patent Document 4 includes a base having wheels at four corners, a support provided on the base, and an arm part (lifting arm) attached to the support. A holding portion for holding a care recipient is provided on the free end of the arm, and the upper part of the care recipient is lifted by the undulation of the arm portion, and the care recipient is transferred onto the base.
Furthermore, the transfer support apparatus disclosed in Patent Document 5 includes a pedestal placed on a floor surface, a support base that is horizontally rotatable on the pedestal, and a slide that is slidably installed on the support base. It comprises a pedestal, a tiltable column, a body holder provided at the tip of the column, and a drive means for tilting the column, and the center of gravity position including the user is determined by the amount of expansion and contraction of the slide pedestal. It is recognized that the configuration is adjusted and controlled.

The outline of the prior art useful for assisting the transfer operation in which an elderly person, a care recipient, a disabled person, etc. transfer from a wheelchair to a bed or vice versa, for example, is illustrated above. However, there are both long and short, and it is not always possible to say that the structure and function can be used safely and sufficiently conveniently.
To put it more extreme, there are concerns about an increase in the number of care recipients, and there are also the reality that there are not enough caregivers, and it is impossible to stand or sit, or elderly people who are not good at such standing and sitting posture and movement. Rotating transfer aids or devices with functions and configurations that help caregivers such as persons with disabilities to turn their directions easily and lightly, and to help independence and support transfer operations, with only a small amount of assistance from an assistant. It has been demanded.

For example, elderly people who need assistance because of physical inefficiency or persons with special needs such as persons with disabilities, will try to transfer to the transfer aid on their own or to get down, but put their first step on their feet. If the rotating disk or the elbow support member that stands and moves even a little (rotates, etc.), the care recipient needs to get on the rotating disk, or to hold the elbow support member itself, and have a strong fear of courage. As a result, it becomes a situation where the desire to use and use is rejected, the use itself is rejected, and the transfer aid becomes useless.
Therefore, it is desirable that the rotating disk on which the care recipient needs to be placed has a structure capable of firmly fixing the position of the rotating disk during the use or at the beginning of the use without causing a slight movement.
In addition, even if people needing care, such as elderly people and people with disabilities, can not maintain their standing posture, it is possible to hold firmly with both hands, and the leaning state is stable and reliable. It also helps caregivers to maintain their standing posture by themselves and to carry out transfer operations (transfers) with relative courage relatively easily. It has been.

  Therefore, an object of the present invention is that an elderly person or a disabled person who cannot stand or sit on his / her own (such as a person who needs care) receives only a small amount of assistance from the wheelchair, and the bed can be moved from the wheelchair. It is useful to safely and relatively easily carry out the operation of transferring from a bed to a wheelchair, etc., or the operation of changing the direction of walking, with stability and security. In addition to assisting independence, it is intended to provide a rotary transfer assisting tool that is useful for reducing the labor of assistants and reducing the burden of working hours.

As a means for solving the above-described problem, a rotary transfer assisting tool according to the invention described in claim 1 is:
The turntable 3 on which the foot 101 of the care recipient (user) 100 is placed on the base member 1 is combined in a configuration that allows horizontal rotation, and the column 5 with the lower end fixed to the turntable 3 is in a vertical posture. And
The turntable 3 is configured to rotate horizontally relative to the base member 1, and pin holes 40 a are provided at a plurality of positions on the circumference of either the turntable 3 or the base member 1. The positioning pin 11 that enters the pin hole 40a and stops the rotation of the rotating disk 3 is installed freely to move forward and backward,
The positioning pin 11 is plunged into the pin hole 40a at a desired position to stop the turntable 3 at a desired rotation angle,
An operating mechanism 15 is installed to pull out the positioning pin 11 from the pin hole 40a and freely rotate the rotating disk 3.
The inner peripheral surface of the ring-shaped base member 1 is formed in a tapered bearing receiving surface 1a that narrows downward,
A bearing receiving surface 3c of the rotating disk 3 is formed in a concentric taper shape having a smaller diameter than the bearing receiving surface 1a of the ring-shaped base member 1 and narrowing downward.
A thrust receiving type bearing ball 3d is installed between the bearing receiving surface 1a of the base member 1 and the bearing receiving surface 3c of the rotating disk 3, and the rotating disk 3 is supported so as to be horizontally rotatable. And

The invention described in claim 2 is the rotary transfer assisting tool described in claim 1,
The base end portions of the plurality of pin hole members 40 having the pin holes 40a toward the center of the turntable 3 are moved from the plurality of positions on the circumference where the rotation angle of the turntable 3 should be set to the center direction of the turntable 3. Protruding and installed on the base member 1,
A positioning pin having a configuration that can be freely moved in and out of the pin hole 40a by being pressed by the action of a spring 11a on the lower surface of the rotating disk 3 that rotates relative to the base member 1 is either The rotation of the rotating disk 3 is stopped by being installed in the pin hole 40a of the pin hole member 40,
The operation mechanism 15 that pulls out the positioning pin 11 from the pin hole 40a and makes the rotation of the rotating disk 3 free can be extracted on the rotating disk 3 by a user's hand or finger operation. It is characterized by a possible configuration.

The invention described in claim 3 is the rotary transfer assist tool according to claim 1 or 2,
A knee pad portion 8 is installed in the middle of the column 5 in the height direction so that the user 100 riding on the turntable 3 holds the knees of both feet and maintains a standing posture. The configuration is such that an elbow support portion 7 on which the user stands is installed.

For example, when transferring from a wheelchair to a bed, the wheelchair is first laid side by side with the bed, and facing the front of the user 100 riding in the wheelchair, the front of the rotary transfer aid of the present invention (left side in FIG. 1). Placed near the bed so that the direction) comes.
Then, the rotating disk 3 on which the user 100 rides is a pin of the pin hole member 40 at an angular position opposite to the front surface provided on the base member 1 (or the rotating board 3, the same applies hereinafter) before the user 100 gets on. The positioning pin 11 is inserted into the hole 40a, and the rotating disk 3 is fixed in advance so as not to move (do not rotate).
Therefore, when the user 100 of the care recipient gets on the turntable 3, the turntable 3 that supports the feet never has to worry about shaking. Therefore, the user 100 puts his feet on the turntable 3 based on a sufficiently high sense of security and reliability (stability), first grabs the elbow support 7 with both hands, and knees of both legs are knee pads. It can be used to stabilize the posture and encourage the person to stand alone.
After that, in preparation for changing the posture to the target direction, the user 100 who has boarded on the turntable 3 is asked to “rotate the turntable 3”, and after “preparation of the mind”, the user or assistance When a person removes the positioning pin 11 from the pin hole 40a by the operation mechanism 15 to make the rotating disk 3 rotatable, the assistant rotates the rotating disk 3 in the direction (angle) of 90 ° (−90 °) from the front. The positioning pin 11 automatically enters the pin hole 40a of the pin hole member 40 at that position again, so that the rotating plate 3 never moves (does not rotate) again.
Therefore, it is possible to safely and safely achieve the purpose of transferring the user 100, who is a care recipient on the fixed turntable 3, toward the bed or chair for the purpose of transfer. In this way, while ensuring safety in use, the psychological confidence is increased, and the care recipient's own motivation for use is increased, which in turn helps independence support, and is also effective in reducing the burden on the caregiver.

  The rotational transfer assisting device of the present invention can safely and safely perform the transformation of the posture to the place or position required by the care recipient without fostering psychological anxiety of the care recipient, After the care recipient needs to be used, it can be easily transported and stored in a warehouse or the like using traveling of the wheels.

The perspective view which showed each component of the rotary transfer assistance tool shown in FIG. 1 in the decomposition | disassembly state. Sectional drawing which looked at the rotational transfer assistance tool in the side surface direction. The top view of a rotary transfer assistance tool. Partial enlarged view of the vicinity of the wheel of the rotary transfer aid The partial enlarged view which made Example 2 the part shown in FIG.

Below, Example 1 of the present invention is described based on Drawings 1-5.
The configuration of the rotary transfer assisting device that is Embodiment 1 of the present invention is a base member 1 that is placed on the floor F via the foot 10 so that the outline of the overall configuration can be inferred from FIGS. On top of this, the rotating disk 3 on which the user (care recipient) places both feet is combined in such a manner that it can freely rotate horizontally, and the lower flange part 5a is connected to the center of the upper surface of the rotating disk 3 with bolts 5b. A column 5 having a hollow tube structure, which is firmly fixed (see FIG. 2), stands in a vertically upward posture.
An attachment in which a knee pad portion 8 on which a user (care recipient) 100 who rides on the turntable 3 hits the knees of both feet is fixed to the column 5 in the middle of the column 5 in the height direction. It is installed on the panel 8a with bolts.
In addition, the upper end of the column 5 can be adjusted to an appropriate height so that a user (care recipient) standing on the turntable 3 can hold it with both hands, and the elbows of both arms are sufficient. The elbow support member 7 of a size that can be worn on the mounting plate 7a has a lower end inserted into the support column 5 so that the height position can be changed in stages, and a bolt is attached to the mounting board 7a that extends to the upper end of the insertion support column 5c that can be expanded and contracted vertically. It is stopped and can be installed at an appropriate height for grasping a care recipient (see FIG. 2).

The structure in which the rotating disk 3 rotates relative to the base member 1 is apparent from the enlarged view shown mainly in FIG. 5, and the inner periphery of the ring-shaped base member 1 having a diameter of 600 mm. The surface is formed on a bearing receiving surface 1a having an appropriate taper shape that narrows downward.
On the other hand, on the lower surface of the turntable 3 mounted on the base member 1, a certain bearing clearance is secured between the inner peripheral surface (bearing receiving surface 1a) of the base member 1 at the outer peripheral portion thereof, and Similarly, the ring-shaped rotary frame 3a is fixed to a plurality of set screws 3b.
A thrust receiving type bearing ball 3d is installed between a bearing receiving surface 1a which is an inner peripheral surface of the base member 1 and a bearing receiving surface 3c which is an outer peripheral surface of the rotating frame 3a. The rotating disk 3 has a structure in which a lower surface of the rotating disk 3 has a gap suitable for horizontal rotation between the upper surface of the base member 1 and has a structure in which horizontal rotation is possible with one rotation center.
With the configuration described above, the rotating frame 3a is fitted through the bearing ball 3d while being surrounded by the base member 1, so that the rotating frame 3a and thus the rotating plate 3 do not slide sideways and are difficult to come off. However, the height H on the floor surface F is as low as possible, and the step H (step amount) when getting on and off of a care recipient who has difficulty or is not good at exercise is small, making it easy to get on and off. ing.
Reference numeral 4 in the figure denotes a non-slip mat laid on the upper surface of the rotating disk 3.

As seen from FIG. 5, the base member 1 is lifted from the floor F by the foot 10, and a gap between the floor F and the lower surface of the base member 1 is used, and the base member 1 is viewed in the direction of FIG. The base end portion 40f, which is bent in a substantially L shape, is placed along the lower surface of the base member 1, and the upper end of the standing piece portion 40b is at a height that does not contact the lower surface of the rotating disk 3 and is closer to the inner side. In the embodiment of FIG. 3, the pin hole member 40 provided with the pin hole 40a in the upright piece 40b is centered on the position of the reference line L in the vertical direction assumed at the center position of the transport wheels 9, 9. The base end portion 40f of the pin hole member 40 is firmly attached to the base member 1 by a plurality of screws 40c. Fixed and installed. However, the position and the number of the pin hole members 40 are not limited to this.
Further, bent portions 40e that are bent outwardly in the horizontal direction are set at both ends of the upright piece 40b. This is an introduction part for automatically projecting a positioning pin 11 described later into the pin hole 40a.
Reference numeral 40d shown in FIG. 3 indicates each pin hole member 40 at a position of ± 90 degrees rotated 90 degrees in both the left and right directions in order to prevent a dark overrun during horizontal rotation of a positioning pin 11 described later. The overrun prevention pin provided in FIG. Naturally, the overrun prevention pin 40d is configured to protrude in the horizontal direction at a position where the main body portion 11a of the positioning pin 11 that rotates horizontally together with the turntable 3 just abuts.

On the other hand, on the lower surface of the turntable 3, on the premise of the above-described configuration and arrangement of the pin hole member 40, as illustrated in FIG. 3, a radially outwardly protruding into any pin hole 40b of the pin hole member 40 is provided. In the posture, one positioning pin 11 is installed in a configuration in which it can freely go in and out of the pin hole of the main body portion 11 a fixed to the lower surface of the rotating disk 3. As shown in FIG. 5, the positioning pin 11 receives a force in a direction of projecting toward the pin hole 40 a of the pin hole member 40 by a coil spring 11 b wound in a spiral shape, and is always pressed. Yes. Therefore, when the positioning pin 11 in a state in which the pin protrudes horizontally rotates together with the turntable 3, the positioning pin 11 is bent to the bent portion 40e that is bent outwardly in the horizontal direction of the pin hole member 40. When the tip of the pin hits and the pin advances along the bent portion 40e, the pin gradually retracts and is introduced into the pin hole 40a, and when it just enters the pin hole 40a, it automatically enters the pin hole 40a by the biasing force of the coil spring 11b. Then, the rotation of the turntable 3 is stopped (see FIG. 3).
Next, a configuration in which the positioning pin 11 is pulled out from the pin hole 40a by the operation mechanism 15 and the rotation of the turntable 3 is made free will be described.
One end of an operation rope 15d is connected to the rear end of the positioning pin 11 via a connector 11c. As shown in FIG. 4, the operation rope 15d is raised into the hollow portion of the support column 5 via a guide roller 14 provided at the lower end position of the support column 5 having a hollow tube structure. It is pulled out through the guide roller 14 at the upper end position and is connected to a movable operation lever 15a prepared on the front lower surface of the elbow receiving member 7 via a detachable roller ratchet 15b. The length of the operation rope 15d can be adjusted by the roller ratchet 15b, and is set to an optimum tension according to the set position of the elbow support member 7.

That is, as the operation mechanism 15, when the movable operation lever 15a is pulled out to the front side, the operation rope 15d connected to the movable lever 15a is pulled, and the positioning pin 11 connected thereto overcomes the acting force of the coil spring 11b and moves backward. The pin hole member 40 is pulled out from the pin hole 40a. As a result, the turntable 3 is free to rotate. As the coil spring 11b is restored, the movable lever 15b is also restored to return to the original position, and the positioning pin 11 also returns to the state in which the pin protrudes.
Therefore, it is free to rotate in either the upper 90 degrees or the lower 90 degrees shown in FIG. 3, and the positioning pin 11 in a state where the pin protrudes horizontally rotates to the bent portion 40 e of the pin hole member 40. As the pin advances along, the positioning pin 11 automatically enters the pin hole 40a and the rotating disk 3 is fixed. Then, since any of the overrun prevention pins 40d protrudes on the rotation radius, the overrun prevention pin 40d interferes and does not advance further in the rotation direction, so that the rotation direction is determined and the transfer position is determined.

In the case of the rotary transfer assisting device according to the present invention, when the care recipient 100 gets on the rotating disk 3 as shown in FIG. It is easy to press against the knee pad 8 to balance the body posture and secure a stable and safe standing posture. Therefore, it is easy to perform an operation of pulling the movable operation lever 15a to the front side with the gripping posture.
What care recipients need to do even a little is important for functional recovery, and it is possible to encourage the way to independence with such participation awareness. Reference numeral 7b in FIG. 2 is an adjustment screw knob 7b for fixing the elbow rest 7 after sliding it up and down according to the height of the care recipient to be used.
In addition, it is also a proposal to install and implement a chair on which the care recipient needs to sit on the turntable 3.

In addition, when the rotary transfer assisting tool is used, a moving wheel 9 is prepared in order to simplify the work of carrying it to the target position or returning it to the storage location.
About the attachment structure of the wheel 9 for a movement, the wheel 9 for a movement is set using the base end part 40f of the pin hole member 40 so that it may become easy to understand when seeing description of FIG. 2 and FIG. 3 together. . From the left and right ends of the base end portion 40f, a pair of wheel support portions 9b are raised upward, and a moving wheel 9 is rotatably attached thereto by an axle 9a. However, when this rotary transfer aid is being used, the lower end of the moving wheel 9 is set to a height that does not contact the floor F so that the moving wheel 9 does not move on the floor F. Installed.
When it is desired to move the rotary transfer assisting tool, if the entire rotary transfer assisting tool is tilted obliquely toward the wheel side (right side in FIG. 3), only the moving wheel 9 is in the state of reaching the floor F. The wheel rotates and can be easily moved to a destination such as a storage location.

Next, the second embodiment of the present invention shown in FIG. 6 has a configuration in which the positional relationship between the positioning pin 11 and the pin hole member 40 is opposite to that of the first embodiment, and the positioning pin 11 is the base member 1. The pin hole 40a is fixed on the rotating disk 3 side and is characterized in that the pin hole 40a is installed on the rotating disk 3 side.
Hereinafter, the description will be focused on different components. The pin hole member 40 provided with the pin hole 40a is fixed to the lower surface of the rotating disk 3 with screws 40c in the direction toward the positioning pin 11. Yes.
On the other hand, the positioning pin 11 that goes into and out of the pin hole 40a of the pin hole member 40 is located on the same radial line as the pin hole member 40a, and the base member 1 is lifted from the floor F by the foot 10. A fixing plate 400f extending along the lower surface of the base member 1 extends toward the center of the rotating disk 3 in the gap between the floor F and the lower surface of the base member 1, and the positioning pin 11 is formed at the tip thereof. The main body 11a is placed and its lower surface is fixed with screws 40c.

  The rear end side of the positioning pin 11 is always pushed to the pin hole 40a side by the coiled spring 11b. The positioning pin 11 enters the pin hole 40a and the rotating disk 3 does not rotate. Then, the operation wire 15d 'extends in the diagonally lower floor direction via a connector 11c provided at the rear end portion (right end portion in FIG. 6) of the positioning pin 11, and is rotatably attached to the fixing plate 400f. The guide roller 14 is run in the horizontal direction and is connected to the tip of the action bar 70a having a short distance between the fulcrums of the lever lever 70 in the vicinity of the end of the fixed plate 400f.

The lever lever 70 is formed in an L shape by an action bar 70a having a short fulcrum distance and an action bar 70b having a long fulcrum distance, and a fulcrum shaft 7c is provided on the outer peripheral surface of the base member. The lever lever 70 is rotatably supported.
When the caregiver pushes the long action bar 70b at the tip of the foot and falls to the base member 1 side, the action bar 70a having a short fulcrum distance rotates in the outer direction of the base member 1, and the operation wire 15d 'is moved to the base member 1. Since the positioning pin 11 is finally connected to the rear end of the positioning pin 11, the positioning pin 11 is pulled out of the pin hole 40a against the urging force of the coiled spring 11b and rotated. The rotation of the board 3 becomes free.
In addition, it is possible to connect the movable operation lever 15a to the movable operation lever 15a as in the first embodiment, and the operation wire 15d 'can be routed. Therefore, in the second embodiment, the operation mechanism to be released is an operation mechanism that performs the release with a foot.

  Although the present invention has been described based on the first and second embodiments shown in the drawings, the present invention is not limited to the illustrated embodiments. It should be noted that the scope of design changes and applications that are usually made by those skilled in the art are naturally included without departing from the technical idea of the present invention.
