Description

Lee Seung Assist Device

[0001] The present invention relates to a transfer assistance device, and more specifically, to a transfer assistance device that ensures stability and provides comfort to a patient during the transfer process.

[0002] For people with disabilities, the elderly, or others whose lower body is damaged or has lost function and thus has limited mobility, it may be necessary for someone to hold them or use a wheelchair or stretcher to transport them to the desired location.

[0003] In addition, when moving from a bed to a wheelchair or from a wheelchair to a vehicle, assistance from an assistant is absolutely necessary. However, if the person is overweight or the route of movement is from indoors to outdoors or vice versa, it is physically difficult and inconvenient for an assistant to transfer, which acts as a factor limiting the movement of the disabled and the elderly.

[0004] To solve these problems, various mobility assistance devices are being proposed to move elderly people or patients with limited mobility to the necessary places or locations.

[0005] Conventional transfer assistance devices use sling sheets to suspend the patient, which not only takes a considerable amount of time for the transfer process, but also poses a risk of falling, as the patient must be lifted to a considerable height before being moved.

[0006] In addition, assistive robots using two actuators have been known in the past, but this technology uses two actuators to operate the lifting part and the arm, respectively, so the lifting motion of the user becomes smooth and the user's comfort is improved, but the use of two actuators has the disadvantage of leading to an increase in cost.

[0007] The technical purpose of the present invention is to provide a transfer assistance device that allows the user to maintain a stable posture by positioning the user's upper body between the front wheel and the rear wheel during the standing process.

[0008] In addition, the technical purpose of the transfer assistance device according to the present invention is to provide a transfer assistance device in which the rotational axis of the actuator is positioned at a low position around the floor, thereby preventing the user's upper body from being kept high during the standing process, thereby allowing the user to maintain a stable posture.

However, even if a description of a component is omitted, it is not intended that such component is not included in any embodiment.

[0089] The transfer assistance device (100) according to the present invention is used to move a user (W), such as an elderly person or a patient with difficulty in moving, from a seated position on a chair (C) to a necessary location or facility (T) in another location after making the user stand up.

[0090] This Seung-Ah auxiliary device (100) is composed of a bottom part (110), a support part (120), an arm part (130), an actuator (140), a support part (150), and a mounting part (160).

[0091] The above floor portion (110) is provided with a footrest for the user's feet to rest on, and a front wheel (113) is provided at the front and a rear wheel (114) is provided at the rear. This floor portion (110) is composed of a floor frame (111), a floor cover (112), a front wheel (113), and a rear wheel (114).

[0092] The floor frame (111) forms the skeleton of the floor (110) and is made of a rectangular frame that is long on the front and back sides and short on the left and right sides.

[0093] A pair of rear wheels (114) spaced apart from each other are installed at the rear of the floor frame (111). Three first beams (1111) extend forward from the rear of the floor frame (111) in a spaced-apart manner. The front of the three first beams (1111) is configured to extend horizontally while being bent upward. The front of the floor frame (111) has a bent shape so as to accommodate a front wheel (113) larger than the rear wheel (114). A second beam (1112) is provided at the center of the floor frame (111) to intersect the three first beams (1111).

[0094] The above floor cover (112) is a portion that covers the upper surface of the floor frame (111) and has a shape that roughly corresponds to the floor frame (111) and is configured to close the open space of the floor frame (111). The floor cover (112) functions as a footrest on which the user's feet are placed.

[0095] The above support member (120) is fixedly installed upward from the floor member (110) and its upper end is positioned at a height corresponding to the user's knee. The support member (120) is installed in the center of the floor frame (111). The support member (120) extends upward from the floor frame (111). This support beam is composed of a first support beam (121) whose upper end is positioned at a height corresponding to the user's knee, and a second support beam (122) which is integrally attached to the front of the first support beam (121) and protrudes upward shorter than the first support beam (121).

[0096] The upper part of the first support beam (121) is rotatably connected to a female part (130), so that the female part (130) can rotate forward and backward with the upper part of the first support beam as the rotation axis.

[0097] The upper end of the second support beam (122) has a lower height than the middle of the first support beam (121). This second support beam (122) is a part that is hinge-type connected to the actuator (140).

[0098] The above arm (130) is rotatably connected to the upper end of the support (120). This arm (130) rotates in either the standing direction or the sitting direction based on the upper end of the support (120).

[0099] At this time, the standing direction means the direction in which the thigh rotates around the knee joint to make the user stand while the user's shin remains perpendicular to the floor (110).

[0100] In addition, the seating direction means one of the seating directions in which the user's shins are kept perpendicular to the floor (110) and the thighs rotate around the knee joint to seat the user, which is the opposite direction to the standing direction.

[0101] This arm (130) is composed of a first extension bar (131) to which a support part (150) is fixedly installed at the rear end and the operating part (142) is connected at the front end, and a second extension bar (132) connecting the upper end of the support part (120) and the middle of the first extension bar (131).

[0102] The first extension bar (131) has the shape of a beam extending in the front-back direction, and the second extension bar (132) is integrally fixedly installed at the center of the first extension bar (131), and the operating part (142) of the actuator (140) is hinge-connected to the front end of the first extension bar (131). A support part (150) is fixedly installed at the rear end of the first extension bar (131). The support part (150) is not directly connected to the first extension bar (131), but is connected to a slider (1311) that protrudes inside and outside the first extension bar (131). By adjusting the protruding length of the slider (1311) according to the user's body size, the support part (150) can be in close contact with the user's chest regardless of the user's body size.

[0103] The second extension bar (132) extends downward from the center of the first extension bar (131) and is installed vertically, crossing the first extension bar (131). When seated, the second extension bar (132) extends upward in the same manner as the support member (120). It is preferable that the upper end of the second extension bar (132) be positioned at approximately the height of the user's upper knees.

[0104] The second extension bar (132) rotates with the upper end of the support member (120) as the pivot point.

[0105] As the second extension bar (132) rotates around the upper part of the support part (120) corresponding to the knee height as the rotation axis, the shin of the user below the knee is maintained in a vertical state with respect to the floor part (110), and the thigh, which is the upper part of the knee, rotates around the knee point of view. In this way, as the second extension bar (132) rotates around a position close to the knee as the rotation center, the process of making the user stand up takes on a form similar to that of an actual person standing up, and the positions of the soles of the feet and the chest take on a form identical to that of actual movement, giving the user a sense of stability.

[0106] In addition, in a standing state, the user's chest is located between the front wheel (113) and the rear wheel (114). Specifically, in a standing state, the user's chest is located in the center of the floor (110) on the upper side corresponding to the support (120), so that there is no problem such as the user's chest being placed on the front wheel (113) or being tilted forward relative to the front wheel (113), thereby increasing stability.

[0107] The above actuator (140) is composed of a body part (141) that is rotatably connected to the support part (120), and an operating part (142) that can be pulled out of the body part (141) or entered into the body part (141), and whose end protruding from the body part (141) is hinge-connected to the front of the arm part (130).

[0108] These actuators (140) are operated by any one of electricity, pneumatics or hydraulics, thereby causing the operating part (142) to move in a straight line.

[0109] The lower part of the body part (141) is rotatably installed on the support part (120). Specifically, the lower part of the body part (141) is rotatably hingedly connected to the second support bar as the lower part of the support part (120). The lower part of the body part (141) is configured to be rotatable at a position close to the floor part (110) and approximately at the center of the floor part (110), so that the body part (141) moves downward toward the front in the process of moving from a sitting position to a standing position.

[0110] At the lower end of the body part (141), a stopper part (1411) is provided so that the second extension bar (132) does not fall backwards while in a vertical position and is configured to contact the support part (120) in a seated state. While the body part (141) can tilt forwards in a seated state, tilting backwards is restricted by the stopper part (1411) of the body part (141) being caught by the support part (120).

[0111] The above operating part (142) is installed so as to be retractable with respect to the body part (141), and when it comes out of the body part (141), it places the user in a standing state, and when it is inserted into the body part (141), it places the user in a sitting state.

[0112] Specifically, when the operating part (142) enters the interior of the body part (141), the body part (141) is inclinedly laid down with the lower end of the support part (120) as the rotation center. At this time, the operating part (142) pulls downward the front end of the first extension bar (131). At the same time, the arm part (130) that rotates with the upper end of the support part (120) as the rotation axis pushes upward the rear end of the first extension bar (131). As the body part (141) is inclinedly laid forward, the rear of the arm part (130) is lifted upward, so that the user can stand up without significantly increasing the height of the user's upper body, thereby providing a sense of stability.

[0113] The above-mentioned support member (150) is fixedly installed at the rear of the arm member (130) and supports a part of the user's body. This support member (150) is composed of a base plate (151), a cushion member (152), and an armpit support member (153).

[0114] The above base plate (151) is fixedly installed to the arm (130) and is installed at an angle to the arm (130). Specifically, the upper end of the base plate (151) is positioned obliquely so that it faces forward and the lower end of the base plate (151) faces rearward.

[0115] The above base plate (151) is formed in a square plate shape.

[0116] The above cushion part (152) is configured to cover the base plate (151), and can be manufactured using a poly-based resin that is easy to clean and maintain in consideration of usability. It can also be provided as a porous panel with multiple penetration holes formed so that water drainage, etc. can be improved when in contact with water, such as when showering, or it can be provided as a porous panel made of a porous material including zeolite, etc.

[0117] The above armpit support portion (153) extends rearward from both sides of the base plate (151) so as to be fitted under the user's armpit. Specifically, the armpit support portion (153) extends from the base plate (151) to both sides, then bends rearward and extends rearward so as to be fitted under the user's armpit.

[0118] This armpit support (153) is composed of a first support (1531) and a second support (1532). The first support (1531) is a portion that extends perpendicular to the front-back direction from both sides of the base plate (151) and then bends to extend rearward. Specifically, as illustrated in Fig. 13, the first support (1531) and the second support (1532) are composed of a support cushion and a support frame. The support frames are hinge-type connected to each other to enable hinge operation.

[0119] The second support part (1532) is a part that is fitted into the armpit between the chest and the arm, and is configured to be hinge-connected to the first support part (1531) so as to rotate in a direction toward or away from the user. In this way, the second support part (1532) is hinge-connected to the first support part (1531), so that the user can wrap the second support part (1532) inward while keeping the chest pressed against the cushion part (152), thereby embracing the entire human body, and making it possible for the user to feel comfortable overall.

[0120] The above-mentioned mounting portion (160) is spaced forward from the support portion (120) and extends upward from the floor portion (110) above the front wheel (113). It is composed of a first mounting bar (1601) extending upward from the floor portion (110) at the rear of the first mounting bar (1601), a second mounting bar (1602) extending upward from the floor portion (110) at the center of the first mounting bar (1601) and being bent toward the first mounting bar (1601) and connected to the first mounting bar (1601). Since the first mounting bars (1601) and the second mounting bars (1602) are provided in plurality, it is possible to prevent the transfer assistance device (100) from being deformed or bent during the process of pushing and pulling the transfer assistance device (100).

[0121] The above-mentioned mounting portion (160) includes a handle portion (161) that is erected upward and has a handle that can be held by a user. The handle portion (161) has a square frame shape and is erected upward, with a rounded edge. After a guide guiding the user holds his / her hand on the upper portion of the handle portion (161), the transfer assistance device (100) can be moved forward and backward.

[0122] The above actuator (140) rotates between the mounting portion (160) and the support portion (120). Specifically, it rotates so that it lies down from the support portion (120) toward the bottom of the mounting portion (160), thereby enabling a stable standing motion.

[0123] In the present invention, drawing number 170 denotes a knee support (170). The knee support (170) is installed on the upper end of the support member (120) and is the part that the knees make contact with when seated. These knee supports (170) are arranged in pairs spaced apart from each other in the left and right directions so that a pair of knees can make contact with the knee supports (170) on both sides.

[0124] Drawing symbol 171 represents a main body case that stores the arm (130), cylinder, and support (120) inside. The arm (130), actuator (140), and support (120) are housed in the main body case (171) that has a housing space inside, thereby preventing the user's hand from being caught in the hinge area during operation, ensuring the user's stability, and providing aesthetic appeal.

[0125] The operation of the assist device (100) according to the present invention is described as follows.

[0126] After moving the transfer assistance device (100) toward the user (W) sitting on the chair (C), the user (W) places his / her feet on the upper surface of the floor (110), as illustrated in FIG. 5. Then, the user (W) places his / her chest against the cushion (152) and his / her knees against the knee supports (170). In addition, the user (W) places the armpit supports under his / her armpits and then wraps his / her hands around the cushion (152) from the front.

[0127] Fig. 6 is a drawing showing the internal appearance by removing the main body case (171) for operational explanation, and the user (W) maintains a seat with his / her knees pressed against the knee support (not shown) as described in Fig. 5.

[0128] Fig. 7 is a perspective view of the inside with the main body case (171) removed, in which the front end of the operating part (142) is pivotally hinged to the front end of the arm part (130), and the lower end of the arm part (130) is rotatably installed on the support part (120).

[0129] Fig. 8 shows the actuator (140) in operation. When the actuator (140) operates, the operating part (142) enters the body part (141), thereby pulling the front end of the arm part (130) downward. As a result, the second extension bar (132) of the arm part (130) rotates with respect to the upper end of the first support beam (121) of the support part (120), causing the front end of the first extension bar (131) to move downwardly forward, and the rear end of the first extension part (131) of the arm part (130) to be lifted upward.

[0130] Since the rotation axis of the armrest (130) is located near the knee of the user (W), when the actuator (140) is driven, the user (W) stands up with the knee joint as the rotation axis. Specifically, while maintaining the same posture as in a seated state with the soles of the feet and shins in position, the upper body with the chest pressed against the support (150) rises forward in a similar manner, lifting the user (W) from the chair.

[0131] Fig. 9 illustrates a state in which the operating part (142) is completely inserted into the body part (141) and the user (W) is completely standing up. When the operating part (142) is completely or almost inserted into the body part (141), the front end of the arm part (130) moves downwardly forward, and at the same time, the rear end of the arm part (130) moves upwardly forward. At the same time, the base plate (151) and the cushion part (152) of the support part (150) are maintained in a substantially horizontal state. Accordingly, the chest of the user (W) is maintained in a substantially horizontal state, and the thighs of the user (W) are almost erected while forming an obtuse angle with respect to the shins, so that the user (W) is maintained in a standing state.

[0132] At this time, the user's (W) chest is positioned between the front wheel (113) and the rear wheel (114), and is positioned directly above the support (120), and the user's (W) upper body including the chest is positioned at the center of the floor (110), thereby enabling the user to maintain a stable posture.

[0133] In addition, since the actuator (140) rotates forward and downward while rotating with the lower part of the support (120) as the rotation axis, the front end of the arm (130) is positioned lower than the upper end of the support (120), and accordingly, the rear end of the arm (130) is not positioned at an excessively high position, so that the upper body of the user (W) is not positioned excessively high even in a standing state, and a stable standing state can be maintained.

[0134] Afterwards, the assist device (100) is moved to another location, and after moving, the rear of the floor (110) can be positioned in front of another facility such as a toilet (T). Afterwards, the operations of FIGS. 6 to 9 are performed in reverse, allowing the user (W) to sit on another facility (T).

[0135] FIGS. 11 and 12 illustrate the operation of the support (150). The support (150) that supports the chest can be positioned in various ways depending on the body size of the user (W). Specifically, the base plate (151) is fixedly installed on a slider (1311) that protrudes inside and outside the first extension (131), so that the length can be adjusted. That is, FIG. 11 shows a state where the slider (1311) is deeply inserted into the first extension (131), and FIG. 12 shows a state where the slider (1311) protrudes from the first extension (131). The slider (1311) slides inside and outside the first extension (131) in a square shape to suit the body size of the user (W), and when an appropriate position is determined, the adjustment bolt (1311a) is fixed.

[0136] The above slider (1311) is configured to be able to slide the first extension (131), and the configuration of the adjustment bolt for position fixation is not limited thereto and various modifications are possible.

[0137] In addition, the base plate (151) can be adjusted in height. Specifically, a slider (1311) can be adjusted to an appropriate position by connecting it to one of the fixing bolts (151b) at the front of the base plate (151) in which a plurality of fixing bolts (151b) are spaced apart from each other in the vertical direction.

[0138] Specifically, the base plate (151) is formed with a plurality of fastening holes (151a) spaced apart in the vertical direction, and the front of the slider (1311) is connected to the base plate (151) through a fixing bolt (151b) that is fastened to one selected from the plurality of fastening holes (151a), so that the height of the base plate (151) can be adjusted in steps.

[0139] The structure in which the above base plate (1311) moves in front of the slider (1311) and the structure in which the base plate (1311) is fixed to any position of the slider (1311) are not limited thereto and various modifications are possible.

[0140] Fig. 13 is an operational view of the armpit support (153). The armpit support (153) is composed of a first support (1531) extending rearward from both sides of the base plate (151), and a second support (1532) hinge-connected to the first support (1531) so as to rotate toward or away from the user (W). When the user (W) leans his / her chest against the cushion (152) and embraces the first support (1531) and then pulls the second support (1532) inward, the second support (1532) forms a shape that embraces the entire body of the user (W). Accordingly, the user (W) can stand up while feeling comfortable, as if a person is embracing the user (W) and making him / her stand up.

[0141] In the above-described embodiment, the body of the actuator is rotatably installed at the bottom of the support, but this is not limited to this, and it is also possible for the body of the actuator to be installed at the bottom as shown in FIGS. 14 to 16.

[0142] Specifically, the assist device (200) according to another embodiment includes a bottom part (210), a support part (220), an arm part (230), an actuator (240), and a support part (250).

[0143] A front wheel (213) is provided at the front lower portion of the floor portion (210), and a rear wheel (214) is provided at the rear lower portion of the floor portion (210). The floor portion (210) is formed in the shape of a rectangular frame, and a body portion (242) is rotatably connected to the front side. Specifically, a connecting piece (211a) protruding upward is formed on the floor frame (211) on the front wheel (213) side, and the lower portion of the body portion (242) of the actuator (240) is rotatably installed on the connecting piece (211a).

[0144] The above support member (220) is fixedly installed upward from the floor member (210) and the upper end is positioned at a height corresponding to the user's knees.

[0145] The above arm (230) is rotatably connected to the upper part of the support part (220) located at the user's knee height and rotates with the upper part of the support part (220) as the center of rotation according to the operation of the actuator (240).

[0146] This arm (230) is composed of a first extension bar (231) to which a support part (250) is fixedly installed at the rear end and the operating part (242) is connected at the front end, and a second extension bar (232) connecting the upper end of the support part (220) and the middle of the first extension bar (231).

[0147] The above actuator (240) is composed of a body part (241) that is rotatably connected to the bottom part (210), and an operating part (242) that can be pulled out of the body part (241) or inserted into the body part (241) and has an end protruding from the body part (241) hinge-connected to the front of the arm part. The lower end of the body part (241) is rotatably installed on a connecting piece (211a) of the bottom frame (211).

[0148] The above support part (250) is fixedly installed at the rear of the above arm part (230) and supports a part of the user's body.

[0149] When the actuator (240) in the assist device for lifting according to the present invention is operated, the front end of the arm (230) is pulled downward, causing the arm (230) to rotate relative to the upper end of the support (229). At the same time, the support (250) positioned at the rear end of the arm (230) rotates to stand up in an upward direction, thereby lifting the user.

[0150] Specifically, when the operating part (242) of the actuator (240) enters the body part (241), the body part is tilted backwards, and at the same time, the front end of the arm part is lowered. At the same time, the support part rotates upward.

[0151] The transfer assistance device (200) according to the present invention has the actuator (240) laid down facing backwards, so that the connection point between the operating part (242) and the arm part (230) moves toward the center of the bottom part (210), thereby positioning the center of gravity at the center. This allows for overall stable operation. In addition, it has the advantage of being easy to have a large turning radius, making it easy to completely stand up the transfer operator.

[0152] Although the present invention has been described in detail above with reference to preferred embodiments, the present invention is not necessarily limited to these embodiments and modifications, and may be implemented in various ways without departing from the technical spirit of the present invention.
