Description

Massage device with a link section that can adjust the width-wise pressure position

[0001] The present invention relates to a massage device, and more particularly, to a massage device having a link part capable of adjusting a widthwise pressure position.

[0002] Working in an improper posture for extended periods can cause acute or chronic pain in the muscles and nerves of the spine. Furthermore, staring at a computer monitor for extended periods or using a smartphone can also cause acute or chronic pain in the muscles and nerves of the cervical spine.

[0003] Massage devices can move along the body to provide thermal stimulation to the painful area, alleviating the aforementioned pain. This stimulation can improve blood circulation and relieve temporary muscle pain.

[0004] Conventional massage devices utilize thermal cathodes capable of generating heat to provide thermal therapy to body parts. Multiple thermal cathodes may be provided, with pairs of thermal cathodes arranged in parallel widthwise, or these pairs of thermal cathodes arranged in multiple rows lengthwise, moving along the body part to provide massage or thermal therapy.

[0005] However, these conventional massage devices have a problem in that they do not reflect the differences in the width of the body parts where heat therapy is performed. For example, when heat therapy is performed on the back (thoracic spine), waist (lumbar spine), and neck (cervical spine), the neck area is very narrow compared to the back or waist area, so if the width-wise gap between the heat electrodes performing heat therapy is maintained based on the back or waist area, the heat electrodes do not make proper contact with the neck area, which causes the heat therapy to not be performed properly.

[0006] Therefore, there is a need to develop a massage device that can effectively massage narrow body parts such as the neck.

[0007] The present invention is intended to solve the above problems, and an object of the present invention is to provide a massage device having a link part capable of adjusting the widthwise pressure position, which can perform massage on a narrow body part such as the neck.

[0008] The tasks of the present invention are not limited to the tasks mentioned above, and other tasks not mentioned will be clearly understood by those skilled in the art to which the present invention pertains from the description below.

[0009] According to one aspect of the present invention, a massage device is provided, which includes a link part capable of adjusting a widthwise pressing position, including a pressing part having a pressing member for pressing a user's body, a link part providing a path for the pressing member to rotate around a longitudinal direction, and a driving part providing a driving force for the link part to rotate.

[0017] At this time, the first transmission link member may be provided with a first hinge axis to which the pressure member and the guide link member are hinge-fixed.

[0018] At this time, the pressurizing part may further include a first support bracket to which the pressurizing member is rotatably fixed around a first pressurizing rotation axis parallel to the width direction.

[0019] At this time, the first support bracket may be provided with a tilting axis so that an angle is formed while the first pressurized rotation axis rotates around the longitudinal direction.

[0020] At this time, the pressing member may be provided with a first elastic member that applies elastic force so that the first support bracket rotates in a first direction facing inward in the width direction.

[0021] At this time, the pressure member may be provided with a stopper that prevents the first support bracket from rotating by a certain angle or more in the second direction when the first support bracket rotates in the second direction facing outward in the width direction.

[0022] At this time, the pressurizing part may further include a second support bracket to which the pressurizing member is rotatably fixed around a second pressurizing rotation axis parallel to the longitudinal direction.

[0023] At this time, the link part may be provided with a second transmission link member that transmits the rotational force of the driving link member to the pressing member, and a second elastic member that applies an elastic force so that the second transmission link member rotates in a third direction facing inward in the width direction.

[0024] At this time, the second transmission link member may be provided with a third hinge axis to which the pressure member is hinge-fixed and a fourth hinge axis to which the second elastic member is connected.

[0025] At this time, the second transmission link member may be provided with a second expansion surface so that the third hinge axis and the fourth hinge axis are spaced apart from each other by a second distance.

[0026] At this time, the second transmission link member may be provided with a third hinge axis to which the pressing member is hinge-fixed and to which the second elastic member is connected.

[0027] According to the above configuration, the massage device having a link portion capable of adjusting the widthwise pressing position according to an embodiment of the present invention is configured such that the pressing member rotates around the lengthwise direction through the link portion to pressurize the user's cervical vertebrae, thereby allowing the gap between a pair of pressing members to be adjusted, so that not only a wide body part such as the back or waist but also a narrow body part such as the neck can be massaged, thereby improving the massage effect.

[0041] Hereinafter, with reference to the attached drawings, embodiments of the present invention will be described in detail so that those skilled in the art can easily practice the present invention. The present invention may be implemented in various different forms and is not limited to the embodiments described herein. To clearly explain the present invention, parts irrelevant to the description are omitted in the drawings, and the same reference numerals designate identical or similar components throughout the specification.

[0042] The words and terms used in this specification and claims should not be construed as limited to their ordinary or dictionary meanings, but should be interpreted in a way that is consistent with the technical idea of ​​the present invention, in accordance with the principles by which the inventor can define terms and concepts in order to best explain his or her invention.

[0043] FIG. 1 is a side view of a massage device having a link part capable of adjusting a widthwise pressing position according to an embodiment of the present invention, FIG. 2 is a perspective view of a massage device having a link part capable of adjusting a widthwise pressing position according to an embodiment of the present invention, and FIG. 3 is a front view of a massage device having a link part capable of adjusting a widthwise pressing position according to an embodiment of the present invention, which is a drawing showing a state before the height of a pressure member rises. Here, the X-axis is a longitudinal direction (axial direction) and means the direction in which the massage device moves along the user's body to massage the user, the Y-axis is a width direction and means the left-right direction of the user, and the Z-axis is a height direction and means the direction in which the pressure member of the massage device rises to pressurize the user. In order to clearly describe the present invention, parts that are not related to the description are omitted from the drawings.

[0044] As illustrated in FIG. 1, a massage device having a link portion capable of adjusting a widthwise pressure position according to one embodiment of the present invention may include a ceramic module (10), a transport portion (20) that moves the ceramic module (10), a control portion (30) that controls the operation of the transport portion (20), and an input portion (40) that inputs a desired thermal treatment pattern by a user.

[0045] Such a massage device may include a main mat (11) used for targeting the user's upper body and his / her spine, and an auxiliary mat (12) used for targeting the user's lower body. In addition, it may include a mounting part (13) for placing and supporting the main mat (11) and the auxiliary mat (12), as needed.

[0046] The ceramic module (10) can massage the spine while moving in the longitudinal direction (X) along the user's spine, and as shown in FIG. 2, the ceramic module (10) can provide a massage effect at an appropriate temperature depending on the massaged location by heating or cooling the pressurizing portion (100) using the current supplied through the control portion (30).

[0047] At this time, the ceramic module (10) may be configured to provide the user with a thermal steaming and massage effect by using not only high-temperature heat but also far-infrared rays.

[0048] The pressurizing part (100) provided in the ceramic module (10) may be formed in a roller shape, but is not limited thereto, and various shapes and structures are possible as long as the pressurizing part (100) is configured to rotate during the movement of the ceramic module (10).

[0049] In addition, when the pressurizing part (100) is formed of a material such as ceramic, far infrared rays are generated during the use of the massage device, which can improve the massage effect. However, it is not necessarily limited to such a material, and it is also possible to form it of another material as long as it can provide a massage effect by transmitting heat to the user's body.

[0050] Additionally, the transport unit (20) may be equipped with a transport drive member that moves the ceramic module (10) in the user's longitudinal direction (X). The transport drive member may include a transport drive motor (21) that reciprocates the ceramic module (10) and a transport member (22).

[0051] The transport drive motor (21) is equipped with a transport rotation shaft that rotates when current is supplied, and the transport member (22) is connected to the transport rotation shaft and transmits the rotational force according to the rotation of the transport rotation shaft to move the ceramic module (10).

[0052] The transfer member (22) is connected to the ceramic module (10) and is used to transfer the ceramic module (10) in one or the other direction along the user's longitudinal direction (X) depending on the forward or reverse rotation of the transfer drive motor (21).

[0053] The transport member (22) can be selectively used among a transport belt, a transport chain, and a transport rope, but is not limited thereto, and various means of transporting the object using the driving force of the transport drive motor (21), such as a method using a lead screw or a rack and pinion, can be used.

[0054] This transport drive motor (21) can be configured to provide driving force while being spaced apart from the ceramic module (10), or to provide driving force while being inserted into the ceramic module (10).

[0055] As illustrated in FIG. 2, this ceramic module (10) includes a pressing part (100) equipped with a pressing member (110) to pressurize the user's cervical vertebrae, a link part (200) that provides a path for the pressing member (110) to rotate around the longitudinal direction (X), and a driving part (300) that provides a driving force for the link part (200) to rotate.

[0056] The pressing member (110) provided in the pressing portion (100) may be provided with a separate heating member to provide a thermal massage effect to the user. In addition, the pressing member (110) may be positioned on one side and the other side in the width direction (Y) with respect to the user's spine as the center, thereby providing a massage effect by pressing acupressure points (for example, acupressure points according to the Foot-Taiyang Bladder Meridian) located on both sides along the user's spine.

[0057] FIG. 4 is a front view of a massage device equipped with a link portion capable of adjusting a widthwise pressure position according to one embodiment of the present invention, and is a drawing showing a state after the height of the pressure member has increased.

[0058] In addition, as illustrated in FIG. 4, the link portion (200) provides a path for the pressure member (110) to rotate around the longitudinal direction (X). That is, as the pressure member (110) rotates around the longitudinal direction (X), the width direction (Y) position of the pressure member (110) changes, thereby adjusting the gap between the pair of pressure members (110), and as the height direction (Z) position of the pressure member (110) changes, the degree of pressing the user's body can also be adjusted.

[0059] In addition, the driving unit (300) provides driving force to rotate the link unit (200), and for this purpose, the link unit (200) may include a driving link member (210) directly connected to a driving rotation shaft (310) provided in the driving unit (300). This driving link member (210) is directly connected to the driving rotation shaft (310) provided in the driving unit (300), thereby improving user convenience.

[0060] That is, the pressure member (110) is configured to rotate around the longitudinal direction (X) through the link portion (200) to apply pressure to the user's cervical vertebrae, thereby allowing the gap between a pair of pressure members (110) to be adjusted, so that massage can be performed not only on a wide body part such as the back or waist, but also on a narrow body part such as the neck, thereby improving the massage effect.

[0061] As shown in FIGS. 3 and 4, the drive link member (210) may include a drive link body (211) fixed to a drive rotation shaft (310).

[0062] That is, one end of the drive link body (211) is directly fixed to the drive rotation shaft (310) and rotates together when the drive rotation shaft (310) rotates in one direction or the other, and a separate fastening member may be provided to fix one end of the drive link body (211).

[0063] At this time, the driving unit (300) may be equipped with a separate gear box so that the torque increases while the rotational speed of the driving rotation shaft (310) decreases.

[0064] As shown in FIGS. 3 and 4, the link member (200) further includes a driven link member (220) that is connected to the driving link member (210) and rotates together, and the driving member (300) may be provided with a driven rotation shaft (320) to which the driven link member (220) is directly connected.

[0065] That is, as described above, the pressure members (110) can be provided on both sides of the user's width direction (Y), and when a driven link member (220) connected to the driving link member (210) and rotating together is provided, a pair of pressure members (110) provided on both sides of the width direction (Y) can be configured to rotate around the length direction (X) through one link driving motor provided in the driving unit (300), thereby simplifying the configuration of the massage device and enabling weight reduction and cost reduction.

[0066] At this time, the driven rotation shaft (320) to which the driven link member (220) is directly connected can be configured to rotate freely without a separate power source being connected, and if configured in this way, the driven link member (220) can rotate smoothly together with the driving link member (210).

[0067] As shown in FIGS. 3 and 4, the driven link member (220) includes a driven link body (221) fixed to a driven rotation shaft (320), and the driving link body (211) and the driven link body (221) may each be provided with a driving gear surface (211a) and a driven gear surface (221a) that mesh with each other.

[0068] That is, one end of the driven link body (221) is directly fixed to the driven rotation shaft (320), but the driven rotation shaft (320) is configured to be freely rotatable, so that when the driving link body (211) rotates according to the rotation of the driving rotation shaft (310) in one direction or the other, the driven link body (221) also rotates together.

[0069] To this end, the drive link body (211) and the driven link body (221) may each be provided with a drive gear surface (211a) and a driven gear surface (221a) that mesh with each other, and if configured in this manner, slippage does not occur between them, enabling stable operation of the pressure member (110).

[0070] At this time, a separate fastening member may be provided to fix one end of the driven link body (221).

[0071] Alternatively, the driving gear surface (211a) and the driven gear surface (221a) may be formed integrally with the driving link body (211) and the driven link body (221), but it is also possible to configure a method in which a separate driving pinion with a driving gear surface (211a) formed and a separate driven pinion with a driven gear surface (221a) formed are respectively arranged and then integrally connected to the driving link body (211) and the driven link body (221).

[0072] As illustrated in FIGS. 3 and 4, the link member (200) may further include a guide link member (230) having a pivot center axis (231) so that the pressure member (110) rotates. The pivot center axis (231) is coupled to one side of the guide link member (230), and the pressure member (110) is coupled to the other side.

[0073] That is, by providing a rotation path of the pressure member (110) through a guide link member (230) that rotates based on the rotation center axis (231), stable movement of the pressure member (110) and precise width direction (Y) and height direction (Z) position control of the pressure member (110) are possible.

[0074] As illustrated in FIGS. 3 and 4, the link member (200) may further include a first transmission link member (240) that transmits the rotational force of the drive link member (210) to the guide link member (230). The drive link member (210) is coupled to one side of the first transmission link member (240), and the guide link member (230) is coupled to the other side.

[0075] That is, the rotational force (rotational torque) of the driving rotation shaft (310) to which one end of the driving link member (210) is fixed is converted into a moment at the other end of the driving link member (210), and when the moment converted at the other end of the driving link member (210) is used to move the first transmission link member (240), the guide link member (230) moves together, and the width direction (Y) and height direction (Z) positions of the pressure member (110) are adjusted.

[0076] In this way, by transmitting the rotational force of the driving link member (210) through the first transmission link member (240), the position of the pressure member (110) can be easily adjusted using a small rotational force.

[0077] At this time, as illustrated in FIG. 3, the driving link member (210) may be configured to be arranged along the height direction (Z) when the pressure member (110) is positioned at the lowest position along the height direction (Z). That is, one end of the driving link member (210) is configured to be arranged at the lower side in the height direction (Z) while the other end of the driving link member (210) is connected to the driving rotation shaft (310).

[0078] With this configuration, when a user's load is applied through the pressure member (110), the load is transmitted to the tartan of the driving link member (210) through the first transmission link member (240). As described above, since the other end of the driving link member (210) is already positioned lower in the height direction (Z) (located at the lowest position), even if the load is transmitted through the first transmission link member (240), the other end of the driving link member (210) can no longer move downward, and thus this state can be maintained even if separate power is not supplied to the driving rotation shaft (310), thereby minimizing power consumption.

[0079] Additionally, as illustrated in FIG. 3, in this state, the first transmission link member (240) and the pressure member (110) can be arranged to form a first angle (θ1).

[0080] As shown in FIGS. 3 and 4, the first transmission link member (240) may be provided with a first hinge axis (241) to which the pressure member (110) is hinge-fixed, and a second hinge axis (242) to which the guide link member (230) is hinge-fixed.

[0081] With this configuration, the position of the first hinge axis (241) to which the user's load is applied through the pressure member (110) and the position of the second hinge axis (242) to which the guide link member (230) is hinge-fixed are mutually separated, so that even when the user's load is applied, stable movement of the pressure member (110) and accurate width direction (Y) and height direction (Z) position control of the pressure member (110) are possible.

[0082] As shown in FIGS. 3 and 4, the first transmission link member (240) may be provided with a first expansion surface (243) so that the first hinge axis (241) and the second hinge axis (242) are spaced apart from each other by a first distance (d1).

[0083] When the first expansion surface (243) is provided in this way, sufficient structural stability of the first transmission link member (240) can be secured, and stable movement of the pressure member (110) and accurate width direction (Y) and height direction (Z) position control of the pressure member (110) are possible even when a user load is applied.

[0084] At this time, the above-mentioned pressure member (110) and guide link member (230) may be configured to be hinge-fixed to the first hinge axis (241) provided in the first transmission link member (240). If configured in this manner, the massage device can be miniaturized.

[0085] FIG. 5 is a cross-sectional view of a massage device having a link portion capable of adjusting a widthwise pressure position according to one embodiment of the invention, and is a drawing showing a state after the height of the pressure member has increased.

[0086] As illustrated in FIG. 5, the pressurizing portion (100) may further include a first support bracket (120) to which the pressurizing member (110) is rotatably fixed about a first pressurizing rotation axis (121) parallel to the width direction (Y).

[0087] At this time, a pressure surface that pressurizes the user can be formed to extend along the circumference of the pressure member (110). When the first support bracket (120) is provided in this way, the pressure member (110) can continuously pressurize the user's body even when it rotates around the first pressure rotation axis (121) while moving along the longitudinal direction (X) while pressing the user's body.

[0088] In addition, the pressure member (110) may be provided with at least two acupressure surfaces to apply pressure to the user at at least two locations along the width direction (Y). At this time, one of the two or more locations may be an acupressure point (second spinal line, acupressure point for treating symptoms related to the internal organs of the body) located about 4.5 cm apart from the user's spine, and the other location may be an acupressure point (third spinal line, acupressure point for treating chronic symptoms related to the internal organs of the body and treating mental symptoms) located about 9 cm apart from the user's spine.

[0089] That is, in order to simultaneously pressurize two or more acupoints while the pressurizing member (110) moves in the longitudinal direction (X), it is important to maintain the arrangement of the acupressure surface constant.

[0090] FIG. 6 is a front view of a massage device having a link portion capable of adjusting a widthwise pressure position according to one embodiment of the present invention, and is a drawing showing a state in which the angle of the acupressure member is changed after the height of the acupressure member is increased.

[0091] As shown in FIGS. 5 and 6, the first support bracket (120) may be provided with a tilting axis (122) so that an angle is formed while the first pressurized rotation axis (121) rotates around the longitudinal direction (X).

[0092] That is, as illustrated in FIGS. 3 and 4, even if the height of the pressure member (110) is adjusted, the first angle (θ1) formed by the first transmission link member (240) and the pressure member (110) can be maintained constant. This is to effectively massage a narrow area, such as the user's neck.

[0093] In addition, as described above, the first support bracket (120) may be provided with a tilting axis (122) so that the first pressure rotation axis (121) rotates around the longitudinal direction (X) to form an angle, and when the tilting axis (122) is provided in this way, even when the height of the pressure member (110) is raised, the horizontal state (parallel state in the width direction (Y)) of the first pressure rotation axis (121) can be maintained, so that the user's waist area can also be effectively massaged.

[0094] At this time, it is preferable that the second angle (θ2) formed by the first transmission link member (240) and the pressure member (110) be formed larger than the first angle (θ1).

[0095] As illustrated in FIG. 5, the pressure member (110) may be provided with a first elastic member (111) that applies elastic force so that the first support bracket (120) rotates in a first direction (a) facing inward in the width direction (Y).

[0096] With this configuration, when the height of the pressure member (110) rises to massage the user's neck, the first support bracket (120) is rotated in the first direction (a) by the first elastic member (111), so that the pressure member (110) can be brought into precise contact with the user's neck.

[0097] In addition, even when the circumferential length of the neck portion is different depending on the user's body shape, when the load of the neck portion is applied to the pressure member (110), the first elastic member (111) is elastically deformed so that the pressure member (110) can be accurately placed on the user's neck portion.

[0098] As illustrated in FIG. 2, the pressure member (110) may be provided with a stopper (112) that prevents the first support bracket (120) from rotating in the second direction (b) by a certain angle or more when the first support bracket (120) rotates in the second direction (b) facing outward in the width direction (Y).

[0099] That is, by configuring the first pressurized rotation axis (121) provided on the first support bracket (120) to be maintained in a horizontal state through the stopper (112) when the pressurized member (110) is positioned at the lowest position along the height direction (Z), effective massage is possible even in a state where a large load is applied, such as to the back.

[0100] At this time, the stopper (112) may also prevent the first support bracket (120) from rotating by a certain angle or more when rotating in the first direction (a) facing inward in the width direction (Y).

[0101] FIG. 7 is a perspective view of a massage device having a link part capable of adjusting a widthwise pressing position according to another embodiment of the present invention, FIG. 8 is a rear view of a massage device having a link part capable of adjusting a widthwise pressing position according to another embodiment of the present invention, and is a drawing showing a state before the height of the acupressure member is raised, and FIG. 9 is a rear view of a massage device having a link part capable of adjusting a widthwise pressing position according to another embodiment of the present invention, and is a drawing showing a state after the height of the acupressure member is raised.

[0102] As illustrated in FIGS. 7 to 9, the pressurizing portion (100) may further include a second support bracket (130) to which the pressurizing member (110) is rotatably fixed about a second pressurizing rotation axis (131) parallel to the longitudinal direction (X).

[0103] By configuring it in this way, when the pressure member (110) rotates around the longitudinal direction (X) and massages the user's neck, the pressure member (110) rotates together, thereby providing a soft massage sensation.

[0104] FIG. 10 is a perspective view of a massage device having a link part capable of adjusting a widthwise pressing position according to another embodiment of the present invention, FIG. 11 is a rear view of a massage device having a link part capable of adjusting a widthwise pressing position according to another embodiment of the present invention, and is a drawing showing a state before the height of the acupressure member is raised, and FIG. 12 is a rear view of a massage device having a link part capable of adjusting a widthwise pressing position according to another embodiment of the present invention, and is a drawing showing a state after the height of the acupressure member is raised.

[0105] As illustrated in FIGS. 10 to 12, the link portion (200) may be provided with a second transmission link member (250) that transmits the rotational force of the driving link member (210) to the pressure member (110), and a second elastic member (260) that applies an elastic force so that the second transmission link member (250) rotates in a third direction (c) facing inward in the width direction (Y).

[0106] A driving link member (210) is coupled to one side of the second transmission link member (250), and a second elastic member (260) is coupled to the other side.

[0107] That is, the rotational force (rotational torque) of the driving rotation shaft (310) to which one end of the driving link member (210) is fixed is converted into a moment at the other end of the driving link member (210), and when the second transmission link member (250) is moved using the moment converted at the other end of the driving link member (210), the second elastic member (260) moves together, and the width direction (Y) and height direction (Z) positions of the pressure member (110) are adjusted.

[0108] In this way, by transmitting the rotational force of the driving link member (210) through the second transmission link member (250), the position of the pressure member (110) can be easily adjusted using a small rotational force.

[0109] In addition, the second elastic member (260) applies elastic force to the second transmission link member (250) to rotate in the third direction (c), so that when the height of the pressure member (110) rises to massage the user's neck, the second transmission link member (250) rotates in the third direction (c) by the second elastic member (260), allowing the pressure member (110) to be in precise contact with the user's neck.

[0110] In addition, even when the circumferential length of the neck portion is different depending on the user's body shape, when the load of the neck portion is applied to the pressure member (110), the second elastic member (260) is elastically deformed so that the pressure member (110) can be accurately pressed against the user's neck portion.

[0111] As shown in FIGS. 11 and 12, the second transmission link member (250) may be provided with a third hinge axis (251) to which the pressure member (110) is hinge-fixed, and a fourth hinge axis (252) to which the second elastic member (260) is connected.

[0112] With this configuration, the position of the third hinge axis (251) to which the user's load is applied through the pressure member (110) and the position of the fourth hinge axis (252) to which the second elastic member (260) is hinge-fixed are mutually separated, so that even when the user's load is applied, stable movement of the pressure member (110) and accurate width direction (Y) and height direction (Z) position control of the pressure member (110) are possible.

[0113] As shown in FIGS. 11 and 12, the second transmission link member (250) may be provided with a second expansion surface (253) so that the third hinge axis (251) and the fourth hinge axis (252) are spaced apart from each other by a second distance (d2).

[0114] When the second expansion surface (253) is provided in this way, sufficient structural stability of the second transmission link member (250) can be secured, and stable movement of the pressure member (110) and precise width direction (Y) and height direction (Z) position control of the pressure member (110) are possible even when a user load is applied.

[0115] At this time, the above-mentioned pressure member (110) and the second elastic member (260) can both be connected to the third hinge axis (251) provided in the second transmission link member (250). That is, the pressure member (110) is hinge-fixed to the third hinge axis (251), and the second elastic member (260) is fixed to the third hinge axis (251). With this configuration, the massage device can be miniaturized.

[0116] As described above, the massage device having a link portion capable of adjusting the widthwise pressing position according to an embodiment of the present invention is configured such that the pressing member (110) rotates around the longitudinal direction (X) through the link portion (200) to pressurize the user's cervical vertebrae, thereby allowing the spacing between a pair of pressing members (110) to be adjusted, so that not only a wide body part such as the back or waist but also a narrow body part such as the neck can be massaged, thereby improving the massage effect.

[0117] Although one embodiment of the present invention has been described above, the spirit of the present invention is not limited to the embodiments presented in this specification, and those skilled in the art who understand the spirit of the present invention will be able to easily propose other embodiments by adding, changing, deleting, or adding components within the scope of the same spirit, but this will also be considered to fall within the spirit of the present invention.
