Summary of the Invention

Problems to be Solved by the Invention

[0004] Improve the manufacturing method of components to reduce costs, when the muscle strength of the care recipient decreases, replace with components that improve the performance of the components of the care product according to the decreasing muscle strength, or attach an electric function to a non-electric care product.

Means for Solving the Problems

[0005] To achieve the above objective, the east and west boards of the wooden house were fixed to the opposing sides of the east and west beams with through bolts, and the horizontal sides of short angles were fixed outwards to the north and south ends of the east and west boards, respectively, and one side of a short intermediate angle was fixed vertically at the midpoint between the east and west boards, and the left and right ends of a south long angle were placed on the horizontal sides of the south short angle on the south side of the east board and the south short angle on the south side of the west board and fixed with bolts, and the left and right ends of a north long angle were placed on the horizontal sides of the north short angles on the north side of the east and west boards and fixed with bolts, and reinforcing short angles were fixed at the midpoint between the south long angle and the north long angle.

[0006] The inner circumference of a short sliding pipe is closely attached to the outer circumference of a central pipe located slightly above the ceiling board. Four square plates with bolt holes are fixed at equal intervals to the outer circumference of the short sliding pipe, and the bolt holes of each of these four square plates are connected and reinforced with four reinforcing flat bars to the bolt holes of the east-west short intermediate angles and the bolt holes of the north-south reinforcing short angles.

[0007] The southern and northern ends of the intermediate plate were placed on the midpoint of the horizontal side of the southern long angle and the midpoint of the northern long angle, respectively, and bolted in place. The head of the upper center bolt, which was screwed into the tapped screw hole at the upper end of the center pipe that was placed in the center hole of the intermediate plate, was then placed on top of the intermediate plate, thereby positioning the upper end of the center pipe on the intermediate plate.

[0008] A thread was machined into the inner circumference of the lower end side of the central pipe that hangs down from the ceiling panel. The threaded portion of the lower central bolt that is inserted into this threaded portion accounts for 20% of its total length, with the remaining 80% being in close contact with the inner circumference of the central pipe. The inner circumference of the lower bearing is positioned on the outer circumference of the lower end of the central pipe. The head of the lower central bolt and the threaded bolt portion act as a fall stopper for the lower bearing. A spacing pipe is placed between the inner ring of the lower bearing and the inner ring of the upper bearing, and an outer ring pipe is placed on the outer circumference of the lower and upper bearings.

[0009] The outer circumferences of the upper and lower bearings are fitted tightly into the upper and lower ends of the inner diameter of the outer ring pipe. The inner circumference of a large washer-shaped section is fitted onto the upper end of the outer circumference of the outer ring pipe and secured. A washer section, which is bolted to the top surface of the large washer-shaped section, has the same outer dimensions, but its inner diameter overlaps the outer ring of the upper bearing by 4 mm. There is a medium-length pipe section that is a continuous, integrally molded part with the washer section. The outer circumference of the center pipe is in close contact with the inner circumference of this medium-length pipe section. The upper end of the round bar section of the lower center bolt is located at this contact point. A horizontal bolt is threaded into the medium-length pipe section and the center pipe at this contact point, and the tip of the horizontal bolt penetrates the upper end of the lower center bolt, preventing the lower center bolt from rotating. The various parts connecting the upper and lower bearings are then connected.

[0010] The shape cut out of the thick plate with a laser is a triangular spear-like space, and the right vertical rectangular bar section is fixed vertically to one point on the outer ring pipe. A right-side rectangular bar section is formed 5 cm long from a position 4 cm below the bottom end of the vertical rectangular bar section, and a horizontal rectangular bar section extending to the left from the bottom end of the vertical rectangular bar section and a diagonal rectangular bar section extending diagonally downward to the left from the top end of the vertical rectangular bar section merge at the merging point. A 5cm long left-hand flat rectangular bar section was cut out from the base to the left, and this left-hand flat rectangular bar section was inserted into an unequal-sided rectangular tube approximately 5cm long. A lid plate was then fixed to the left side of the inserted section, and the top edge of the unequal-sided rectangular tube was placed on top of the upper end of the left-hand flat rectangular bar section and secured with bolts. Similarly, the right-hand unequal-sided rectangular tube was inserted into the upper end of the right-hand flat rectangular bar section, and its top edge was placed on top of it and secured with bolts. A lid was then fixed to the right side of the unequal-sided rectangular tube.

[0011] A right-side grooved ring is fixed inside the right-side unequal-sided rectangular tube, and a left-side grooved ring is fixed inside the left-side unequal-sided rectangular tube. The balance string wrapped around the right-side grooved ring hangs down from the right side of the groove and suspends the balance weight. The balance string that suspends the balance weight is positioned at the pivot point, and the balance string extending to the left from the right-side grooved ring is wrapped around the left-side grooved ring and connected to the suspension holder.

[0012] An unequal-sided rectangular pipe column, which raises and lowers the balance weight, has a rectangular pipe column fixed to its side, and a power cord is fixed to the side of the rectangular pipe column, with the overlap at the upper end of the fixed part removed. The power cord that hangs down from the left groove of an outer ring groove fixed to the removed part suspends the balance weight, and the power cord that hangs down from the right groove is wound onto a cord winding ring fixed inside a U-shaped power mechanism. A reduction gear and a gear motor with brake are connected to the rotating shaft that rotates the cord winding ring and fixed on a large plate, and a cover is fixed to the upper end of the unequal-sided rectangular pipe column and the rectangular pipe column, and a circular pipe handrail and control panel are attached to the cover.

[0013] This is an electric balance-type body transfer device that allows the person being cared for to lower a hanging holder to eye level by operating a remote control by their pillow, then unfasten the string holes of their underwear attachment belt from the buttons and attach it to the hanging holder, then use the remote control to stand up, and then move to the wheelchair with shuffling steps in a small turn while holding onto a circular pipe handrail and operating the control parts, and then sit down in the wheelchair. The rotation center position of the balance string hanging from the right side of the grooved ring on the right outer ring makes it easy to attach the electric device, and furthermore, it is an electric balance-type body transfer device that makes it easy to attach and detach parts in order to attach parts that are sized to fit the person being cared for. [Effects of the Invention]

[0014] By laser-processing many of the components, the cost is reduced. For those receiving care with a balance support capacity of up to 17 kg, a non-electric, small-swing body transfer device is used. Using a non-electric device slows down muscle weakness, but if muscle strength declines over time, a balance weight is attached to match the muscle strength, and the device is converted to an electric one.

Mode for Carrying Out the Invention

[0016] A method for attaching an electric motor to a non-electric small swing balance body transfer device according to one embodiment of the present invention is described. The inner surfaces of the east beam TB and west beam NH facing each other were fixed to the east plate TB and west plate NB with through bolts, respectively. Short angles were fixed to the north and south ends of the east plate TB and west plate NB with their horizontal sides facing outwards. One side of a short intermediate angle TYUA was fixed vertically at the midpoint between the east plate TB and west plate NB. The left and right ends of the south long angle MTA were placed on the horizontal sides of the south short angle ANM on the south side of the east plate TB and the south short angle ANM on the south side of the west plate NB and fixed with bolts. The left and right ends of the north long angle KTA were placed on the horizontal sides of the north side of the east plate TB and west plate NB and fixed.

[0017] Four square plates KA with bolt holes are fixed at equal intervals to the outer circumference of the slide pipe SRP, which is in close contact with the inner circumference of the outer circumference of the central pipe TYUP located near and above the ceiling plate TE. Short intermediate angles TYUA are fixed to the midpoint between the east plate TB and the west plate NB. The southern and northern ends of the intermediate plate TUBB are placed on the midpoint of the horizontal side of the south long angle MTA and the midpoint of the north long angle KTA, respectively, and fixed with bolts. The head of the upper central bolt UTB is screwed into the tapped screw hole at the upper end of the central pipe TYUP, which is placed in the hole at the center of the intermediate plate TUBB, and the head of the bolt is placed on the intermediate plate, thereby installing the upper end of the central pipe TYUP on the intermediate plate.

[0018] A tapped thread is machined into the inner circumference of the lower part of the central pipe TYUP, which is located slightly below the ceiling panel TE. The remaining 80% of the round bar portion of the lower central bolt CTB, which is screwed into the threaded hole (20% of its total length), is made to be in close contact with the inner circumference of the central pipe TYUP. A spacing pipe NKP is placed between the inner ring of the lower bearing BEC and the inner ring of the upper bearing BEU, which are located at the lower end of the outer circumference of the central pipe TYUP. An outer ring pipe GRP is placed on the outer circumference of the outer rings of the upper bearing BEU and the lower bearing BEC. The inner circumference of a large washer W is fixed to the outer circumference of the upper end of the outer ring pipe GRP, and the bolt is fixed on the upper surface of the large washer W. The washer portion WW has the same outer diameter and its inner diameter is positioned so that it overlaps the outer ring of the upper bearing BEU by 4 mm. The medium-length pipe portion TYP is a continuous, integrally molded part with the washer portion WW. The outer circumference of the center pipe TYUP is in close contact with the inner circumference of the medium-length pipe portion TYP, and the upper end of the round bar portion of the lower center bolt CTB is located at this point of contact. The horizontal bolt YB is screwed into the medium-length pipe portion TYP and the center pipe TYUP at this point, and the tip of the horizontal bolt YB is inserted into the upper end of the lower center bolt CTB, thereby preventing the lower center bolt CTB from rotating and connecting the various parts that connect the upper bearing BEU and the lower bearing BEC.

[0019] The components that attach to or fix the outer ring pipe GRP become parts of the small swing mechanism of the balance-type assistive device, and the majority of this small swing mechanism is made inexpensive by laser cutting from a single thick plate.

[0020] The thick plate is laser-cut into a triangular spear shape with an internal cavity. The right vertical rectangular bar section TAK is fixed vertically to one point on the outer ring pipe GRP. A 5cm long right rectangular bar section M5B is cut out and positioned 4cm below the bottom end of the outer ring pipe GRP, extending to the right. A horizontal rectangular bar section SKB is extended horizontally to the left from the bottom end of the vertical rectangular bar section TAK. A diagonal rectangular bar section NAKB is extended from the top end of the vertical rectangular bar section TAK, so that the diagonal rectangular bar section NAKB and the horizontal rectangular bar section SKB merge. A 5cm long left rectangular bar section H5B is then extended to the left from the point of merging. The left flat bar section H5B is extended, and the left unequal-sided rectangular tube HFT is placed inside the left unequal-sided rectangular tube HFT, with the top edge of the left unequal-sided rectangular tube HFT resting on the top end of the left flat bar section H5B, and the resting point is bolted in place. Similarly, the right flat bar section M5B is placed inside the right unequal-sided rectangular tube MFT, with the top edge of the right unequal-sided rectangular tube MFT resting on the right flat bar, and the balance weight GG inside the unequal-sided rectangular tube column F is suspended. The balance string HH extending to the left from the right outer ring grooved ring MGRNG is wrapped around the left outer ring grooved ring HGRNG, lowered to the left side, and connected to the suspension holder TUH, thereby connecting the balance weight GG and the suspension holder TUH and creating a balance.

[0021] An unequal-sided rectangular pipe column F, which raises and lowers the balance weight GG, has a rectangular pipe column DF fixed to its side, which raises and lowers the power cord DH. The overlap at the upper end of the fixed column is removed, and the power cord DH that hangs down from the left groove of the outer ring grooved ring RNG fixed to the removed portion suspends the balance weight GG, while the power cord DH that hangs down from the right groove is wound onto a cord winding ring HMR fixed inside a U-shaped power mechanism DD. A reduction gear GEN and a gear motor with brake M are connected to the rotating shaft that rotates the cord winding ring HMR and fixed to a large plate D. Covers FTK are fixed to the upper ends of the unequal-sided rectangular pipe column F and rectangular pipe column DF, and a circular pipe handrail ENP and an operation panel SWB are attached to the cover FTK.

[0022] This method involves operating a remote control placed by the bedside to lower the hanging holder TUH in front of the user, grabbing the hanging holder to raise the upper body, attaching the belt sash detached from the chest button to the hanging holder, operating the control panel SWB while sitting in bed, grabbing the pipe handrail ENP to stand up, shuffling a short turn to move to the wheelchair, sitting down, detaching the belt sash from the hanging holder TUH, and going to the toilet. This method involves adding an electric function to a non-electric short-turn personal mobility device to create an electric short-turn personal mobility device. [Explanation of Symbols]
