Description

Technical field

 TECHNICAL FIELD The present invention relates to a functional carrier capable of placing and carrying a transported object including a person and a load and changing the direction and placing it.

 Background art

 book

 The recent transition to an aging society with the extension of life expectancy has led to an increase in elderly people with physical disabilities (hereinafter referred to as “elderly people etc.”) The need for care in daily life is increasing. Especially when the number of living alone increases, the carer often takes care of the surroundings, especially when going to the hospital regularly, for example, there is a way to put a wheelchair into a taxi etc. However, it is difficult to spread because it is limited to special vehicles and it costs money. You may switch from a wheelchair to a regular passenger or a taxi, but it is difficult for the caregiver to do this alone.

 The first to third rails are constructed between the car chair and the rear seat of the vehicle as a device for transferring the elderly people to the seat in the vehicle while sitting in a wheelchair. A sheet transfer apparatus has been proposed which performs loading and unloading by lowering the arm rest and moving along the rails (see, for example, Japanese Patent Application Laid-Open No. 2002-222416).

However, the seat transfer device disclosed in the above-mentioned Japanese Patent Laid-Open No. 200202-22464 is provided between the wheelchair stopped near the vehicle with the rear door open and the rear seat on which the mounting plate is placed. The first to third rail portions must be erected, and it is difficult to erect the first to third rails in a stable state. In particular, sliding the seat without a backrest along each rail is much more unstable when considering the sinking of the seat on the vehicle side, and it is dangerous when considering the elderly people. In addition, it is difficult for the seat to bend and slide in the corner because the rails are not only straight. The Also, because the rear seat is equipped with mounting plates and rails, the space occupied by other carers will be blocked.

 In addition, conversely, when carrying out the same operation from the vehicle to the wheelchair again, there is a possibility that the work efficiency and stability may be lost, and it may be difficult for the carer to work alone. . Disclosure of the invention

 An object of the present invention is to provide a functional carrier capable of repeatedly carrying out an operation of placing and transporting an object to be transported including people and luggage with a simple configuration and changing the direction of the object. .

 In order to achieve the above object, a functional carrier according to the present invention has the following configuration.

 In a functional carrier that can place and transport objects to be transported including people and luggage, and change its direction and direction, a support arm is provided on the bogie main body so that it can move up and down. The mountable mounting portion is characterized in that it is rotatable along the longitudinal direction of the support arm and detachably connected in the vertical direction.

 A chair with a support arm vertically movable on the bogie main body, a seat, an armrest, a backrest, and a leg holder, is rotatable along the longitudinal direction of the support arm and can be detachably connected in the upper and lower directions. The chair is rotatably supported by rolling along a guide groove formed in the longitudinal direction of the support arm, and a bearing provided at the lower part of the armrest portion.

 Further, the chair connects the armrest side connecting portion provided at the lower portion of the armrest portion with the arm side connecting portion of the auxiliary arm portion which can slide along the guide groove formed in the longitudinal direction of the arc-shaped arm main body. And the chair is rotatably supported along the guide groove together with the auxiliary arm portion.

 Furthermore, the armrest portion of the chair is formed in a ring shape in which a guide groove is formed in the longitudinal direction and is divisible, and the guide groove of the armrest portion is connected to a guide opening provided rotatably on the support arm. It is characterized in that it is rotatably supported.

In addition, the support arm is connected to and separated from the bogie main body by linking to the first movable part movable along the upper and lower frame parts on both sides of the bogie main body via the link mechanism. A second movable unit, which is supported on the upper side of the first movable unit and which can be driven by the drive source and can move along the upper and lower frame units on both sides, is connected to the link mechanism. When the drive source is driven to move the second movable part up and down, the support arm and the first movable part linked together via the link mechanism are interlocked together, and the link mechanism is tilted when the link mechanism is tilted. The movable portion of the vehicle is moved up and down, and the support arm is moved in contact with and separated from the bogie main body.

 Alternatively, the support arm is movably supported on and off the carriage main body by linking via a link mechanism the first movable portion movable along the upper and lower frame portions on both sides of the carriage main body by drive transmission from the drive source. The second movable part and a part of the link mechanism that is provided above the first movable part and can move up and down along the upper and lower frame parts on both sides and is locked to the stopper to restrict the downward movement position. When the drive source is driven to move the first movable part upward, the support arm connected via the link mechanism moves in a direction away from the carriage main body, and the first movable part is moved. If you move the first movable part upward while keeping it in contact with the second movable part locked to the stopper, the second movable part is engaged with the stopper. Stop and stop, and further move the first movable part down the link machine Support arm through is thus being moved in the direction you close to a truck body.

 Further, the seating portion is characterized in that a seating arm for supporting the thigh is provided so as to be able to open and close on both sides. In this case, a seat provided between the seating arms and capable of supporting the buttocks may be pivoted to a position overlapping the backrest so as to be able to open and close the seating part. A receiving portion for receiving the thigh on the tip end side of the arm may be provided so as to be tiltable with respect to the arm body.

 The seat and / or the backrest of the chair is characterized in that a long adjusting belt capable of adjusting the tension while a person is sitting is installed. In addition, the adjustment belt installed on the seat portion and the Z or the backrest portion is characterized in that the cushion material is inserted and annularly wound around the frames on both sides so that the tension can be adjusted.

The adjustment belt is looped on both sides of the frame through the retaining ring connected on both sides of the seat material laid on the seat and / or the back of the chair, and the tensioning belt is tensioned. Are set up in an adjustable manner.

 By using the functional carrier described above, the support arm is provided on the carriage main body so as to be capable of moving up and down, and the placement portion on which the object to be transported can be placed is rotatable along the longitudinal direction of the support arm. Since the package is detachably connected to each other, the luggage is placed on the placement unit, transported while pushing the main body of the carriage, and changed depending on the orientation and height position of the placement unit as necessary. be able to. Therefore, the worker can save the labor of transporting and replacing the transported object.

 In particular, when the functional carrier is a wheelchair, even a single carer can easily transfer the elderly person etc. from the wheelchair to the vehicle and from the vehicle to the wheelchair. In addition, by moving the bottom frame of the car body into the bottom of the vehicle at the height range of the vehicle and rotating the chair as the placement unit supported by the support arm, the vehicle with the door opened was limited. The space can be used to change the direction of the chair, and the support arm can be lifted up or down to an arbitrary height, so that elderly people sitting in the chair interfere with the seat of the vehicle etc. It is possible to move into the vehicle and put it back together.

 Further, the armrest side connecting portion provided at the lower part of the chair arm portion is connected with the arm side connecting portion of the auxiliary arm portion which can slide along the guide groove formed in the longitudinal direction of the arc-shaped arm main body. When the chair is rotatably supported along the guide groove together with the auxiliary arm, the notch of the arm body can be connected by the auxiliary arm to rotate the chair. The stability of is good.

 Further, the armrest portion of the chair is formed in a ring shape in which a guide groove is formed in the longitudinal direction and can be divided, and the guide groove of the armrest portion is connected to a guide opening provided rotatably on the support arm. If it is rotatably supported, the rotation on the chair's support arm will be improved, and the area required for rotation will not exceed the diameter of the armrest, thus requiring less work space.

In addition, when the drive source is driven to move the second movable part up and down, when the support arm and the first movable part linked together via the link mechanism are interlocked integrally, Lift up the support arm to the desired height position and then tilt the link mechanism to move the support arm horizontally forward of the truck body Can. Also, when the drive source is driven to move the first movable part upward, the link mechanism is tilted to move the support arm away from the carriage main body and move forward, and to the second movable part locked to the stopper. With the first movable portion in contact, the support arm can be integrally moved upward to a desired height position while holding the front orientation of the support arm. In addition, when the first movable part is moved downward, the second movable part is first engaged with the stopper and stopped, and when the first movable part is further lowered, the height position of the support arm is maintained while maintaining the link. Fold the mechanism and move it back close to the truck body. Therefore, if the height position of the second movable part is determined in advance, the support arm can be moved to the front position at a desired position, and the first movable part is further moved upward to move the support arm. You can adjust the height position.

 Furthermore, when a seating arm for supporting the thighs is provided so as to be able to open and close on both sides of the seating part of the chair, a caregiver can easily shift the bedridden elderly person etc. to a wheelchair alone in a wheelchair. It is easy to use the toilet while it is on the wheelchair. In addition, if a long adjustment belt capable of adjusting tension while a person is sitting is installed on the seat and Z or backrest of the chair, the tension of the seat and backrest may be used. It can be adjusted to sit according to the person's body shape and unique posture. In addition, the adjustment belt installed in the seat and the back or the seat may be wound around the cushion material and annularly wound around the frames, or may be connected to both sides of the seat laid in the seat and / or the seat back. If the adjustment belt is looped on both sides of the frame through the retaining ring, adjusting the tension of the adjustment bell improves the comfort of the chair and the person sitting in the chair The tension can be adjusted individually without being dragged by the belt.

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. As an example of the functional carrier according to the present invention, a wheelchair carrying and carrying elderly people with physical disabilities will be described as a representative example.

First, the configuration of the wheelchair will be described with reference to FIGS. In FIG. 1, 1 is a wheelchair, and is configured as follows. Reference numeral 2 denotes a bogie main body, which is composed of an upper and lower frame portion 3 and a bottom portion frame portion 4. The bottom frame portion 4 is provided with free wheels 4 a at the left and right at two places in the front, and at the left and right two places with free wheels 4 b at the rear. The wheelchair 1 can be traveled by the wheels 4 a and 4 b by holding the handle 5 protruding horizontally in the upper and lower frame portions 3 and pushing the cart body 2. All the front and rear wheels may be the free wheels 4a or only the rear wheels 4a.

 A support arm 6 is provided on the upper and lower frame portion 3 so as to be movable up and down. The support arm 6 is configured such that the left and right guide portions 6 a move up and down along the upper and lower frame portions 3. The support arm 6 supports a chair 7 as an example of a placement unit. As the chair 7, for example, a metal pipe-like frame, in which a cloth such as cloth or mesh is stretched (not shown in FIG. 1) is preferably used. Support arm 6, for example, a chair

An arc-shaped arm is used in which the front of 7 is notched over approximately 90 degrees.

 The chair is rotatable along the longitudinal direction of the support arm 6, and the support arm

It connects with the 6 in the up-down direction so that attachment or detachment is possible. Specifically, chair 7 has a seating section

3 7, armrest 8, backrest 3 8 and leg holder 9 are provided. The leg holder 9 is provided so as to be able to adjust the back and forth and / or the upper and lower positions of the chair 7. Further, in FIG. 2, the chair 7 is rotatably provided along the guide groove 11 provided in the longitudinal direction of the support arm 6 by the bearings 10 provided at the lower part of the armrest 8 at four places. . When the chair 7 is rotated 90 degrees clockwise or counter clockwise from the state in which the armrest 8 is supported at four points, one of the left and right bearings 10 on the front side is a guide groove

Although it is out of orbit from 1 1, it can be rotated at three points supported by other bearings 10 so that it can rotate stably even when a person is on chair 7. The figure

In 2, the backrest 3 8 and the leg holder 9 of the chair 7 are omitted.

 Further, in FIG. 10, a guide roller 39 is supported by the armrest 8 by a support member 40 so as to be capable of coming into and coming out of contact with each other. The support member 40 is provided movably to a guide position suspended in contact with the armrest 8 and a separated position separated from the armrest 8. Chair

In the case of rotating 7, the support member 40 is moved to the guide position, and the guide hole 3 9 is brought into contact with the guide surface 4 1 formed in the longitudinal direction of the support arm 6 to roll. By doing this, the chair 7 can be rotated smoothly. Further, when the chair 7 is to be lifted, the support member 40 may be separated to allow the armrest 8 to move upward.

 Further, in FIG. 3, the vertical movement mechanism 32 of the support arm 6 will be described. The supporting arm 6 is linked via a nut portion 12 to a rod screw 13 rotatably supported in the vertical direction on the upper and lower frame portions 3 of the carriage body 2. A bevel gear 14 is provided at the upper end of the rod screw 13, and the bevel gear 15 is engaged with the bevel gear 14. An operating handle 16 is linked to the rotation shaft of the bevel gear 15 as an example of a driving means. Therefore, when the caregiver rotates the operation handle 16 in a predetermined direction, the rod screw 13 is rotated via the bevel gears 15 and 14. As a result, the support arm 6 linked to the rod screw 13 via the nut portion 12 is moved in any of the upper and lower directions. The drive source of the drive means is not limited to the operation of the carer's handle, and an electric motor, a servomotor, a hydraulic motor, a hydraulic cylinder or the like may be used. Also, as a drive transmission mechanism, a mechanism for moving a movable portion by rotating a ball screw connected to a servo motor, a movement mechanism by combining rack and pinion gear, a movement mechanism by a piston moving up and down in a cylinder A variety of drive transmission mechanisms can be adopted, such as a movement mechanism using a pantograph or toggle link, or a movement mechanism in which a movable part is connected to a bell chain that is wound between movable elevator wheels.

Next, a working procedure in which a carer puts an elderly person etc. alone into a car using the wheelchair 1 described above will be described with reference to FIGS. 4A to 4E. First, in Fig. 4A, open the front passenger seat or rear seat door of vehicle 17. With an elderly person placed in the wheelchair 1, turn the operating handle 16 to raise the support arm 6 and lift up the chair 7. Next, in FIG. 4B, make the wheelchair 1 obliquely enter the space of the open door of the vehicle 17 and turn the armrest 8 in the counterclockwise direction by 90 ° on the support arm 6 as shown in FIG. 4C. As shown in the figure, the bottom frame 4 of the wheelchair 1 is pushed into a gap with the ground of the vehicle 17. A normal car has a gap of about 20 cm with the ground, so if the bottom frame 4 is designed to have a reduced height, the bottom frame 4 can be used for all vehicles in the height range. It is possible to enter is there. At this time, since the support arm 6 is lifted up, the one sitting on the chair 7 does not interfere with the seat 18 on the car side. Although it is preferable for the door of the vehicle 1 7 to be as open as possible for operation, even in the normal opening and closing range, the chair 7 can be turned to the side of the vehicle 1 7 on the seat 18 with the chair 7 entering by rotating the chair 7. It can be made to enter.

 In FIG. 4D, the chair 7 can be placed on the seat 18 by turning the operating handle 16 in reverse and lowering the support arm 6. Then, turn the operation handle 16 to separate the support arm 6 from the armrest 8 of the chair 7. In this state, as shown in FIG. 4E, the wheelchair 1 is pulled apart from the vehicle 17 and the door is closed to complete the transfer work.

 It should be noted that the chair 7 on which the elderly people and the like sit can be taken in a stable state without putting a burden on the elderly people and the like by putting on the seat belt with the seat 7 placed on the seat 18. In addition, when the chair 7 is fabric-lined on the pipe frame, it is not inferior to sitting directly on the seat 18 and there is no harm to the sitting comfort.

In addition, when chair 7 is rotated 90 degrees along arc-shaped support arm 6, a gap is created between the back portion of chair 7 and the arm, but the backrest of seat 18 of vehicle 17 is tilted. By adjusting it, it can be put on the seat 18 without shifting.

In the case of getting the elderly people out of the vehicle 17, they can be transferred to the wheelchair 1 in the reverse order of the steps shown in FIGS. 4A to 4E. That is, with the support arm 6 in the lower position with the door of the vehicle 17 opened, the bottom frame portion 4 of the wheelchair 1 is pushed into a gap with the ground in the vehicle height range of the vehicle 17. At this time, position the support arm 6 at the bottom of the armrest 8 of the chair 7 sitting on the seat 18. Then, turn the operation handle 16 to raise the support arm 6 to support the bearing 10 of the armrest 8 by the guide groove 11 and lift up the chair 7 on the seat 18. In this state, pull wheelchair 1 away from vehicle 1 7 and turn armrest 8 clockwise on support arm 6 90 degrees to make the elderly people sitting in chair 7 look forward. Can. Then, by turning the operating handle 16 in the reverse direction and lowering the support arm 6, it is possible to return to the state of being seated on the chair 7 before riding. According to the configuration described above, even a single carer can easily transfer an elderly person or the like from wheelchair 1 to vehicle 17 or from vehicle 17 to wheelchair 1. In particular, by moving the bottom frame 4 of the bogie main body 2 into the bottom of the vehicle in the height range of the vehicle and rotating the chair 7 supported by the support arm 6, the door 17 is limited. The space can be used to turn in the direction of the chair 7 and the support arm 6 can be lifted up or down to an arbitrary height. The seat can be replaced without interfering with the seat, etc. When used as a wheelchair 1, it is also possible to use a stopper so that the chair 7 does not rotate unexpectedly.

 Next, another example of the support arm 6 will be described with reference to FIG. 5 and FIG. In FIG. 2, the support arm 6 is formed in a circular arc shape which is cut out over approximately 90 degrees, but as shown in FIG. 5, one end of the circular arc arm portion 30 provided over approximately 180 degrees The rod-like arm portion 31 may be connected to the portion so as to be rotatable outward around the rotation supporting point 19. The rod-like arm portion 31 is provided at a position substantially parallel to the armrest portion 8 of the chair 7 and vertically overlapping. A guide groove 11 in which a bearing 10 rolls is formed in the arc-shaped arm portion 30 and the rod-shaped arm portion 3 1, and a bearing 10 is provided in three places in an armrest portion 8 of the chair 7 . The rod-like arm 31 is connected to a torsion coil spring (not shown) or the like so as to be held at the position shown in FIG. When the chair 7 is rotated in a counterclockwise direction, the rod-like arm 31 is moved along the guide groove 11 of the rod-like arm 31 when the bearing 10 of the armrest 8 is moved. Once rotating 1 clockwise about the rotation support point 1 9 (see the broken line in FIG. 5), when chair 7 rotates 90 degrees, it returns to its original position again (see the solid line in FIG. 5). In this case, since the position of the rod-like arm 31 coincides with the position of the back of the chair 7, the seat 7 can be put on the seat without adjusting the reclining of the seat on the vehicle side.

As another example, in FIG. 6, the support arm 6 is provided at both ends of an arc-shaped arm 30 provided at approximately 90 degrees at a position corresponding to the backrest portion of the chair 7. It may be connected so as to be openable and closable outward from the parallel state around the rotation support point 19 respectively. The rod-like arm 3 1 is an armrest 8 of a chair 7 and They are respectively provided at substantially parallel and overlapping positions. A guide groove 11 in which a bearing 10 rolls is formed in the arc-shaped arm portion 30 and the rod-shaped arm portion 31. The armrest 8 of the chair 7 is provided with bearing 10 at six locations. ing. That is, the bearings 10 rolling on the rod-like arm portions 31 on both sides are provided at two places, and the bearings 10 rolling on the arc-shaped arm part 30 are provided at two places. This is because the rotation trajectory of the chair 7 and the rotation trajectory of the rod-like arm 31 are different on both sides. Each rod-like arm 31 is connected to a torsion coil spring or the like (not shown) so as to be held at the position shown in FIG. In this case, the position of the rod-like arm 31 matches the position of the backrest of the chair 7 even if the chair 7 is rotated 90 degrees in either direction (counterclockwise Z clockwise). The seat can be put on the seat without adjusting the reclining of the seat on the side. As a result, the vehicle can be placed on either the left or right door, and can be placed on the passenger seat of a left-hand drive as well as the right-hand drive, improving versatility.

 Next, a wheelchair according to another example will be described with reference to FIGS. 7 AB and 8 AB. In FIG. 8 AB, substantially the same members as in FIG. 7 AB will be assigned the same reference numerals as in FIG.

 In FIG. 7A, the dolly main body 20 is constituted by the left and right frames 21. A rotating shaft 23 connecting the upper and lower frame portions 22 is connected in two foldable via a universal joint 24. Bar screws (not shown) are rotatably supported vertically at the left and right upper and lower frame parts 22. An operating handle 16 is linked to one of the rod screws via a bevel gear. In addition, the mounting plate 25 of the support arm 6 is frequently connected to the rod screw on both sides at a not-shown nut portion. The mounting plate 25 is detachably engaged with the nut portion of one upper and lower frame portion 22. When the operation handle 16 is turned in the specified direction, the rod screws provided on the left and right upper and lower frame parts 22 simultaneously rotate via the rotation shaft 23, and the support arm 6 attached via the mounting plate 25 is It has become possible to raise and lower.

At the lower part of the left and right bottom frame parts 26, two free wheels 26 a are provided at a total of four places at two places, and the bogie main body 20 is supported for traveling. The left and right bottom frame parts 2 6 are at the two ends of the rocking link material 2 7 which intersects at the intersection 2 7 c Each is linked. One end 2 7 a of the rocking link 2 7 is rotatably connected to the front side of the bottom frame portion 26, and the other end 2 7 b is slidable in the longitudinal direction of the bottom frame portion 26 It is linked to the slide member 2 8 linked. The slide member 28 is designed to be able to fix the position on the bottom frame portion 27 in the folded position and the assembled position.

 After placing an elderly person on the chair 7 and putting it on a car, as shown in FIG. 7B, release the locked state of one side of the mounting plate 25 connected to the upper and lower frame parts 22. The mounting plate 25 may be locked as long as the other side can be rotated as long as the locking state with the upper and lower frame portions 22 on one side can be released. Then, the rotary shaft 23 is folded in two at the center of the universal joint 24 so that the left and right upper and lower frame parts 22 come close to each other. Also, slide the slide member 28 to which the other end 2 7 b of the swing link 2 7 is linked to slide in the longitudinal direction of the bottom frame portion 26 so as to bring the left and right bottom frame portions 2 6 closer to each other. As a result, it is possible to place the chair 7 and fold the truck body 20 left and right, put it on an open space such as a car trunk, a carrier or a rear seat, and improve portability.

 Alternatively, in FIG. 8A, the upper and lower frame portions 35 may be supported by the link 36 while the truck body 33 stands on the rectangular bottom frame 34. The upper and lower frame portions 35 are provided with an operating handle 16 and a rotary shaft 23 connected between rod screws (not shown) as in FIG. 7A. In addition, the support arm 6 is movably connected to the upper and lower frame parts 35 vertically through the mounting plate 25. At the lower part of the bottom frame portion 34, there are provided a total of four free wheels 3 4a, which support the bogie main body 33 so that it can travel.

Further, in FIG. 8B, the support arm 6 may be rotated upward to overlap the upper and lower frame portions 35 by releasing the engagement between the mounting plate 25 and the upper and lower frame portions 35. It is possible. Further, by releasing the upright support of the upper and lower frame portions 35 by the link 36, the bottom frame portion 34 is connected so as to be able to overlap the upper and lower frame portions 35. As a result, the chair body 3 can be placed back and forth, and the carriage body 3 3 can be folded back and forth, placed on an open space such as a car trunk, a carrier or a rear seat, and portability can be improved. . The above illustrates the case where the elderly person etc. are transferred to the car together with the chair 7 supported by the wheelchair 1. However, the present invention is not limited to this case. For example, it may be used to transfer the patient from the wheelchair 1 to the bed at a hospital or the like. Also good. If the chair 7 can be placed on the bed in a state of being rotated 90 degrees, it can be moved to the bed by only the patient's own parallel movement, so that the labor can be moved with less.

 Further, as shown in FIG. 9, the chair 7 may be a pipe bed 29 in which a cloth is stretched on a seat portion 29a, a backrest portion 29b, and a leg support portion 29c. In this case, since the inclination angles of the backrest portion 29b and the leg support portion 29c can be arbitrarily changed with respect to the seat portion 29a, it is also possible to place them on the bed as they are. . Next, another example of a wheelchair will be described with reference to FIGS. 11 to 29. The same members as those in the wheelchair described above are given the same reference numerals and their descriptions are incorporated.

 In FIG. 11 and FIG. 12, the support arm 6 uses an arc-shaped arm main body 42 cut out approximately 90 degrees at the central angle.
