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 the patient during the transfer process.

[0002] For individuals with disabilities or the elderly whose mobility is limited due to lower body damage or loss of function, it is necessary to carry them or use a wheelchair or stretcher to move them to their desired location.

[0003] Furthermore, assistance from a caregiver is mandatory when transferring from a bed to a wheelchair or from a wheelchair to a vehicle; however, physical difficulties and inconveniences arise when a caregiver assists with transfers due to heavy body weight, movement from indoors to outdoors, or vice versa, which acts as a limiting factor for the mobility of people with disabilities and the elderly.

[0004] To address these problems, various mobility aids are being proposed to move elderly people or patients with limited mobility to necessary locations.

[0005] Conventional lifting assistance devices use sling seats to suspend the patient, which not only requires a significant amount of time for the lifting operation but also poses a risk of falls as the patient is lifted to a considerable height before being moved.

[0006] Conventionally, in order to transfer a patient lying in bed, the upper body of the patient lying down is raised, the patient is turned 90 degrees to change their position so that they can face the transfer aid, and then the transfer aid is pushed into the bed to attempt the transfer. However, since it is not easy to turn a patient with limited mobility to the side to face the transfer aid in this way, there is a disadvantage that it is difficult to transfer the patient with only one caregiver.

[0007] The technical objective of the lifting assist device according to the present invention is to provide a lifting assist device that enables lifting operations without changing the patient's position so that the patient is in a position facing the lifting device by human power.

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

[0105] The lifting assistance device (100) according to the present invention is used to move a user, such as an elderly person or a patient with limited mobility, from a seated position in a chair to a necessary place or facility at another location after standing up.

[0106] This lifting assist device (100) is configured to include a bottom part (110), a support part (120), an arm part (130), an actuator (140), a base part (150), an armpit support part (160), and a mounting part (170).

[0107] The above-mentioned floor portion (110) is provided with a footrest on which the user's feet are placed, 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).

[0108] The bottom frame (111) forms the framework of the bottom part (110) and is made of a rectangular frame with long front and rear sides and short left and right sides.

[0109] A pair of spaced-apart rear wheels (114) are installed at the rear of the floor frame (111). A plurality of first beams (1111) extend from the rear of the floor frame (111) toward the front, spaced apart to the left and right. A second beam (1112) extending horizontally is provided at the center of the floor frame (111) to which the end of the first beam (1111) is connected, and a third beam (1113) extending in the front and rear directions is spaced further apart than the first beam (1111) in front of the second beam (1112).

[0110] Among the plurality of third beams (1113), the beam positioned in the center is extended straight forward and then bent upward to stand upright, and the beams positioned on both sides of the plurality of third beams (1113) are configured to be bent upward from the middle and then extended forward.

[0111] At the front end of the plurality of third beams (1113) mentioned above, a fourth beam (1114) connecting the plurality of third beams (1113) to each other is extended in the left and right directions. Front wheels (113) are configured to be installed at the lower ends of both ends of the fourth beam (1114). Since the rear wheels (114) are formed larger than the front wheels (113), the fourth beam (1114) supporting the front wheels (113) is positioned higher than the first beam (1111) on which the rear wheels (114) are installed.

[0112] The floor cover (112) is configured to cover the upper surface of the floor frame (111), have a shape that corresponds approximately to the floor frame (111), and close the open space of the floor frame (111). The floor cover (112) functions as a footrest on which a user's foot is placed.

[0113] The support member (120) is fixedly installed by being erected upward from the floor member (110), and its upper end is positioned at a height corresponding to the user's knee or slightly higher than the knee. The support member (120) is installed at the center of the floor frame (111), that is, at an intermediate position between the front and the rear. The support member (120) extends upward from the floor frame (111).

[0114] An arm (130) is rotatably connected to the upper part of the support member (120), so that the arm (130) can rotate and move forward and backward using the upper part of the support member (120) as a rotation axis.

[0115] The above arm (130) is rotatably connected to the upper end of the support member (120). This arm (130) rotates in either the standing direction or the sitting direction relative to the upper end of the support member (120).

[0116] At this time, the standing direction refers to the direction in which the user is made to stand up by rotating the thigh around the knee joint while the user's shin remains perpendicular to the floor (110).

[0117] Additionally, the sitting direction refers to any one of the sitting directions opposite to the standing direction, in which the user is seated by rotating the thigh around the knee joint while the user's shin remains perpendicular to the floor (110).

[0118] In this arm (130), a support part (150) is fixedly installed on the other side, which is the rear end, and an operating part (142) of an actuator (140) is connected to the one side, which is the front end.

[0119] The arm (130) has the shape of a beam that extends long in the front-rear direction, and a support member (120) is rotatably connected to the center of the arm (130), and an operating part (142) of an actuator (140) is hinge-connected to the front end of the arm (130). A support member (150) is fixedly installed at the rear end of the arm (130). The support member (150) is not directly connected to the arm (130) but is connected to a slider (131) that moves in and out of the arm (130). By adjusting the protruding length of the slider (131) according to the user's body dimensions, the support member (150) can be in close contact with the user's chest regardless of body dimensions.

[0120] In the standing position, the user's chest is located between the front wheel (113) and the rear wheel (114). Specifically, in the standing position, the user's chest is positioned at the center of the bottom part (110) as an upper side corresponding to the support part (120), thereby increasing stability by preventing problems such as the user's chest being placed on the front wheel (113) or tilting forward relative to the front wheel (113).

[0121] The actuator (140) comprises a body part (141) rotatably connected to the front of the bottom part (110), and an operating part (142) that can exit from the body part (141) or enter into the body part (141), with an end protruding from the body part (141) being hinge-connected to the front of the arm part (130).

[0122] This actuator (140) is operated by electric, pneumatic, or hydraulic power, and accordingly causes the operating part (142) to move in a straight line.

[0123] The lower end of the body portion (141) is rotatably installed on the third beam (1113) of the floor frame (111) in front of the floor portion (110). Specifically, it is installed on the central beam among the plurality of third beams (1113) and is rotatably installed in front of the third beam (1113).

[0124] The present invention is configured such that the lower end of the body part (141) can rotate from the center in the left and right directions of the bottom part (110), so that during the process of moving from a sitting position to a standing position, the body part (141) moves downward toward the front.

[0125] The above operating part (142) is installed so as to be extendable with respect to the body part (141), and when it comes out of the body part (141), it places the user in a standing position, and when it is inserted into the body part (141), it places the user in a seated position by rotating the front end of the arm part (130) downward.

[0126] Specifically, when the operating part (142) enters the interior of the body part (141), the body part (141) is tilted backward with the front of the bottom part (110) as the center of rotation. At this time, the operating part (142) pulls the front end of the arm part (130) downward. At the same time, the rear end of the arm part (130), which rotates with the upper end of the support part (120) as the axis of rotation, is pushed upward. When the body part (141) is tilted backward, the rear of the arm part (130) is lifted upward, thereby allowing the user to be placed in an upright state without the height of the user's upper body being significantly raised, thus providing a sense of stability.

[0127] The support member (150) is fixedly installed on a slider (131) positioned at the rear of the arm (130) as the other side of the arm (130). The support member (150) supports a part of the user's body, specifically the user's chest. This support member (150) is composed of a support bar (151) installed at the other end of the arm (130), a support plate (152) that is length-adjustably coupled to the support bar (151), and a central cushion member (153) that covers the support plate (152).

[0128] The support bar (151) is fixedly installed on the slider (131) and is positioned upright in the vertical direction. Specifically, it is positioned obliquely at a predetermined angle so that the upper end of the support bar (151) is positioned slightly forward of the lower end when seated. A plurality of fastening grooves spaced apart from each other are formed in the support bar (151), and a position fixing pin (155) is installed in the fastening hole (1511). The position fixing pin (155) is configured to be inserted into the fastening hole (1511) of the support bar (151) after passing through a protruding plate (1521) positioned on the front of the support plate (152).

[0129] A bracket is installed at the front lower end of the support bar (151), and a strap hole (1512) is formed in the bracket. A butt strap (183) is fixed to the strap hole (1512). After wrapping the butt strap (183) around the upper part of the user's buttocks, if the butt strap (183) is fixed to the strap hole (1512), the user can continuously maintain a state of contact with the central cushion part (153) while standing.

[0130] The above-mentioned base plate (152) is formed in the shape of a thin rectangular plate and is connected to the base bar (151) in a length-adjustable manner. The above-mentioned base plate (152) performs the function of supporting the central cushion part (153) and is configured to be inserted inside the central cushion part (153).

[0131] A pair of protruding plates (1521) that are vertically extended and spaced apart from each other are fixedly installed on the front surface of the base plate (152). The spacing between the protruding plates (1521) may have a thickness corresponding to the thickness of the base bar (151). A plurality of through holes (1521a) are formed in the protruding plates (1521), and a position fixing pin (155) is configured to pass through the through holes (1521a) of the protruding plates (1521).

[0132] After inserting the support bar (151) between a pair of protruding plates (1521) and adjusting the upper and lower positions of the support plate (152), the position fixing pin (155) is inserted and inserted, thereby fixing the position and allowing the support plate (152) to be fixed in an appropriate position that fits the user's body size.

[0133] The support bar (151) is supported with both sides in close contact with the protruding plate (1521) and the rear side in close contact with the support plate (152), so that three sides are in contact with the protruding plate (1521) and the support plate (152), allowing for stable fixed support.

[0134] The central cushion part (153) is covered with a base plate (152) and has a sponge installed inside to provide a cushioning sensation to the user's chest.

[0135] This central cushion portion (153) is formed in a roughly rectangular shape and can be in contact with the user's chest on the rear side. First cushion portions (164) are configured to be provided on both sides of the central cushion portion (153).

[0136] On the front of the above-mentioned base plate (152), an arm rest (154) is provided, which has a "U" shape that is open in the left and right directions and into which the user's forearm below the elbow is inserted.

[0137] The above arm support (154) is composed of a rear plate (1541) that contacts the front of a base plate (152), a front plate (1542) that is spaced apart from the front of the rear plate by the width of the forearm, and a connecting part (1543) that integrally connects the lower ends of the front plate (1542) and the rear plate (1541).

[0138] It is fixedly installed on the support plate (152) with the support bar (151) in between, and is configured to be fixedly installed on the front of the support plate (152) using a predetermined bracket. When the user lifts their upper body from the bed and inserts their left or right arm into the armrest (154), it prevents the user from turning their body toward the transfer aid (100) or from the user's body moving backward or rapidly forward while lifting their upper body from the bed during the transfer process.

[0139] The above armpit support (160) is positioned on the left and right sides of the support member (150) and extends backward toward the user's armpit to support the user's armpit. The armpit support (160) is configured to protrude from each side of the support member (150) and extend backward. The armpit support (160) supports the user's body, and when the arm is inserted into the armrest (154), the armpit support (160) supports the left and right sides of the user's torso.

[0140] These underarm support members (160) are rotatable between an unfolded position in which the user approaches in a left-right direction perpendicular to the front-rear direction and the user’s chest can come into contact with the support member (150), and a folded position in which the user is folded so as to be fitted into the user’s underarm when the user’s chest comes into contact with the support member (150) and restricts the user from moving in the left-right direction.

[0141] These underarm support parts (160) consist of a fixed part (161), a rotating part (162), a rotation regulating part (163), a first cushion part (164), and a second cushion part (165).

[0142] The above fixing part (161) protrudes from both the left and right sides of the support part (150). Specifically, it is configured to protrude from both the left and right sides of the support plate (152) and extend in a bent state toward the rear. The support part (150) is formed in the shape of a rectangular plate, and the fixing part (161) is fixedly installed at nearly right angles to both edges of the support plate (152). Reinforcing ribs for reinforcement may be installed between the fixing part (161) and the support plate (152).

[0143] The above-mentioned rotating part (162) is rotatably installed on the above-mentioned fixed part (161) by means of a hinge part (166) and rotates between a folded position and an unfolded position. Specifically, the rotating part (162) is connected to the fixed part (161) by means of a hinge part (166), such as a hinge, and is configured to be rotatable with respect to the free end of the fixed part (161). When the rotating part (162) extends in approximately the same direction as the fixed part (161) and is positioned in a direction approximately perpendicular to the base plate (152), this is called the folded position, and when the rotating part (162) is positioned approximately parallel to the base plate (152), this is called the unfolded position.

[0144] The rotating part (162) is formed in the shape of a thin rectangular plate and is installed with its longer side extending in the front-rear direction. On the inner surface of this rotating part (162), a scapula support part (1621) is installed to support the user's scapula by protruding inward. The scapula support part (1621) may have the shape of a triangular plate that protrudes from the rotating part (162) and protrudes inward as it moves further away from the fixed part (161).

[0145] This scapula support (1621) is intended to support the user's scapula when the user has the armpit support (160) fitted into the armpit, and can perform the function of supporting the user when the user (H) is lifted from the bed (B) by the operation of the actuator (140) so that the arm (130) rotates relative to the support. The scapula support (1621) can support the lower part of the scapula that can be caught on the back.

[0146] A belt hole is formed at each free end of the rotating part (162) to stably support the user so that the user does not slip out of the armpit support part (160) when the user's chest comes into contact with the central cushion part (153). A belt (182) is fitted into the belt hole (1622) of each rotating part (162), and the user's back can be tightened by the belt (182).

[0147] The above rotation control part (163) defines the position of the rotation part (162) so that the user does not move left or right when the user's chest comes into contact with the support part (150) while the rotation part (162) is folded.

[0148] The rotational regulating member (163) comprises a fixed plate (1631) fixedly installed on the fixed member (161), a locking latch (1632) rotatably installed on the fixed plate (1631), a locking member (1633) installed on the rotating member (162) and engaged with the locking latch (1632) when the rotating member (162) is placed in a folded position, and an elastic bias member (1634) that elastically biases the locking latch (1632) to the locking position.

[0149] The above fixing plate (1631) is installed horizontally at the bottom of the fixing part (161). The fixing plate (1631) is installed at the bottom of one side of the fixing part (161) and is installed protruding from both sides of the fixing part (161).

[0150] A second pin portion (1631a) and a rotating pin (1631b) are installed on the fixed plate (1631). The second pin portion (1631a) is installed spaced apart from the first pin portion (1632c) and protrudes upward from the upper part of the fixed plate (1631). The second pin portion (1631a) is configured to support one side of the elastic bias member (1634). One end of the elastic bias member (1634) is formed in a ring shape, and the one end of the elastic bias member (1634) is supported by being hooked onto the second pin portion (1631a).

[0151] The rotating pin (1631b) passes through the locking latch (1632) and is fixedly installed on the fixing plate (1631). The locking latch (1632) is configured to rotate with the rotating pin (1631b) as the center of rotation.

[0152] The locking latch (1632) is configured to rotate between a locking position, where the hook portion (1632b) engages with the locking portion (1633), and a separation position, where the hook portion (1632b) is separated from the locking portion (1633). Specifically, the locking latch (1632), which rotates around the rotating pin (1631b), is configured to rotate between the locking position and the separation position.

[0153] The locking latch (1632) includes a latch body (1632a) rotatably connected to the fixed plate (1631), a hook part (1632b) disposed on one side of the latch body (1632a) and capable of engaging with the locking part (1633), and a first pin part (1632c).

[0154] The above latch body (1632a) is composed of a first part (1632a1) in the form of a straight bar and a handle part (1632a2) extending perpendicularly from the center of the first part (1632a1). A rotating pin (1631b) is configured to be inserted into the center of the first part (1632a1).

[0155] The handle portion (1632a2) extends from the first portion (1632a1) and protrudes outward from the fixing portion (161) past the lower end of the fixing portion (161), so as to be gripped by a user or caregiver. By grasping and rotating the handle portion (1632a2), the user or caregiver enables the latch body (1632a) to rotate to a separated position.

[0156] The above hook portion (1632b) is positioned on one side of the latch body (1632a) and is formed in a hook shape to engage the catch portion (1633). When the catch portion (1633) is engaged with the above hook portion (1632b), the rotation of the rotating portion (162) is restricted and the position of the rotating portion (162) can be fixed. When the latch body (1632a) moves to the separation position, the above hook portion (1632b) is separated from the catch portion (1633), allowing the rotating portion (162) to rotate freely.

[0157] The first pin portion (1632c) is positioned on the other side of the latch body (1632a) and is formed to protrude upward from the latch body (1632a). This first pin portion (1632c) is configured to support the other side of the elastic bias member (1634). The other end of the elastic bias member (1634) is formed in a ring shape, and the other end of the elastic bias member (1634) is supported by being caught on the second pin portion (1631a).

[0158] One side of the elastic bias member (1634) is connected to the fixing plate (1631) and the other side is connected to the other side of the latch body (1632a) so that the latch body (1632a) is elastically biased to the locking position.

[0159] When a user or caregiver applies force while gripping the handle portion (1632a2), causing the latch body (1632a) to rotate from the locked position to the unlocked position, the elastic bias member (1634), which is made of a tension coil spring, is extended. Additionally, when the user or caregiver removes force from the latch body (1632a), the latch body (1632a) is configured to move back to the locked position by the restoring force of the elastic bias member (1634). Thus, the elastic bias member (1634) causes the latch body (1632a) to maintain the locked position, thereby allowing the rotating portion (162) to maintain the folded position when the user or caregiver does not apply a separate force.

[0160] The first cushion part (164) covers the fixing part (161) and is designed to provide a cushioning sensation to the user's arm or armpit by containing a sponge inside. This central cushion part (153) has a roughly rectangular shape and is configured to have a receiving part extending from the lower side upward inside. The receiving part is configured to be fitted with the fixing part (161).

[0161] An anti-detachment protrusion (1641) is formed on the upper part of the first cushion part (164). The anti-detachment protrusion (1641) is formed such that one side adjacent to the second cushion part (165) is raised upward, and the other side adjacent to the support part (150) is relatively lower in height. When the user's arm is placed on the other side of the support part (150), the anti-detachment protrusion (1641) catches the user's arm, thereby preventing the user from falling backward and performing the function of positioning the user.

[0162] The above mounting portion (170) is spaced forward from the support portion (120) and extends upward from the bottom portion (110) above the front wheel (113).

[0163] The above mounting portion (170) includes a handle portion (171) that is positioned upward and is provided with a handle that can be grasped by a user. The handle portion (171) has a square frame shape and is positioned upward, with a rounded edge. After a guide guiding the user grasps the top of the handle portion (171), the riding assistance device (100) can be moved forward and backward.

[0164] In the present invention, reference numeral 180 indicates a knee support (180). The knee support (180) is installed on the upper part of the support member (120) and is the part that contacts the knee while in a seated state. These knee supports (180) are arranged spaced apart from each other in a pair of left and right directions so that a pair of knees can come into contact with both knee supports (180).

[0165] Drawing reference numeral 181 indicates a battery section (181) in which a battery is placed. An electrical signal generated from the battery section (181) supplies power to an actuator (140) so that the actuator (140) operates by operation by a user or caregiver.

[0166] Drawing reference numeral 182 is a belt (182) that connects the armpit support members (160) by fixing both ends to the belt holes (1622). When the armpit support members (160) are connected by the belt (182) after the user is positioned within the armpit support members (160), the user is not able to slip out of the armpit support members (160) and can be positioned stably inside the lifting assist device (100).

[0167] Drawing reference numeral 183 is a buttock strap (183) that is placed over the upper buttocks of the user. After the buttock strap (183) is placed over the user's buttocks in a loop shape, the buttock strap (183) is secured to the strap hole (1512). When the buttock strap is placed over the upper buttocks of the user and secured by hooking it to the strap hole (1512) in this manner, the user's body does not slip backward while moving in an upright state, and the chest can stably maintain contact with the central cushion part (153).

[0168] Reference numeral 184 is a main body cover (184) that houses a support member (120), an arm member (130), and an actuator (140) inside. In the present invention, the main body cover (184) is formed only on one side and the main body cover (184) is not formed on the other side. This is to show the external appearance and the internal structure simultaneously.

[0169] The operation of the transfer assistance device (100) according to the present invention is described as follows with reference to FIG. 18.

[0170] As illustrated in FIG. 18(a), the user (H) is moved to the edge of the bed (B), and then the lifting assist device (100) according to the present invention is moved to the side of the bed (B). At the same time, one of the pair of armpit support members (160) is rotated to an unfolded position.

[0171] Then, as shown in FIG. 18(b), only the upper body of the user (H) is raised. At this time, the upper body of the patient enters the front of the support part (150) through the space opened by the unfolded armpit support part (160).

[0172] Although not shown in the drawing, one of the patient's arms can be inserted into the armrest (154) to allow the patient to maintain a stable posture.

[0173] Then, as shown in FIG. 18(c), the armpit support (160) that was in the unfolded position is rotated to the folded position. Accordingly, the user can be placed between a pair of armpit support (160). Then, by fastening the belt (182) to the end of the armpit support (160), the user is prevented from falling during the rotation process.

[0174] Afterward, as shown in FIG. 18(d), the user is rotated about 90 degrees so that the user's chest comes into contact with the support member (150). Specifically, the user is positioned so that they sit on the edge of the bed and face the lifting assist device. With the belt (182) fastened, the user placed between the armpit support members (160) is rotated 90 degrees, thereby allowing them to maintain a stable posture.

[0175] Afterward, as illustrated in FIG. 18(e), the user's body can be brought into close contact with the transfer aid (100) by placing the buttocks strap (183) against the user's buttocks. Specifically, the buttocks strap is hung on the top of the user's buttocks to complete the preparation for the transfer.

[0176] Afterwards, as shown in FIG. 18(f), the actuator (140) is actuated, and accordingly, the arm (130) rotates the upper part of the support (120) around the center of rotation, thereby causing the user in a seated state to stand up.

[0177] The transfer assist device (100) according to the present invention has the following effects.

[0178] The lifting assist device (100) according to the present invention has the advantage that at least one of the pair of armpit support members (160) can be rotated to an unfolded position, thereby allowing the lifting operation to be performed without the user having to position themselves to face the lifting assist device (100).

[0179] The lifting assist device (100) according to the present invention has a shoulder blade support (1621) provided in the armpit support (160) so that the user does not fall out of the lifting assist device (100) during the lifting process.

[0180] The lifting assist device (100) according to the present invention forms a protrusion (1641) for preventing detachment on the armpit support (160), thereby stably holding the user's posture and preventing the user from slipping backward.

[0181] The lifting assist device (100) according to the present invention has the advantage of preventing the body from suddenly springing forward during the process of the user standing up by providing an armrest (154) in front of the armpit support (160). In addition, the user and the lifting assist device (100) can maintain a close contact state.

[0182] The transfer assist device (100) according to the present invention can be modified as follows.

[0183] In the above-described embodiment, the front wheel (113) and rear wheel (114) of the riding assist device (100) are directly fixed to the floor (110), but this is not limited thereto, and it is also possible to additionally install a weight measuring unit (190) to measure the user's weight.

[0184] A weight measuring unit (190) for measuring the user's weight is provided on either the front wheel (113) or the rear wheel (114), and the weight measuring unit (190) stops measuring the weight when the user's weight is above a certain level.

[0185] At this time, the weight measuring unit (190) includes a stop plate (191), a movable plate (192) positioned on the upper part of either the front wheel (113) or the rear wheel (114) and hinged to the stop plate (191), a support plate (193) positioned on the upper part of the movable plate (192) spaced apart from the movable plate (192) and fixedly installed on the stop plate (191) and connected to the floor part (110), a scale (194) positioned between the movable plate (192) and the support plate (193) to measure the weight of the user when the user rides, and the stopper (195) fixedly installed at the end of the support plate (193).

[0186] Additionally, the end of the movable plate (192) is inserted into the stopper (195), and a slot (1951) is formed to limit the oscillation distance of the movable plate (192) so that the distance between the movable plate (192) and the support plate (193) does not become less than a certain amount.

[0187] When the user's weight exceeds a certain level, the end of the movable plate (192) is configured to come into contact with the inner wall of the slot (1951) and be fixed in position. When the user places their body on the footrest, the movable plate (192) rotates relative to the stop plate (191), and in the process, the gap between the movable plate (192) and the support plate (193) narrows, thereby measuring the user's weight.

[0188] Typically, there is a risk of damage to the scale (194) when measuring a weight above a certain level, but since the end of the movable plate (192) is configured to be movable within the slot (1951), damage to the scale (194) can be prevented by stopping the weight measurement when the user's weight exceeds a certain level.

[0189] 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 variations, and can be implemented in various modified ways within the scope of the technical spirit of the present invention.
