Description

Pressurized rod capable of measuring user load

[0001] The present invention relates to a massage device, and more particularly, to a pressure rod capable of measuring a user's load.

[0002] Traditionally, spinal thermal massage devices have been widely used to alleviate acute or chronic pain in the muscles and nerve tissues of the spine caused by prolonged work in an improper posture or by habitually maintaining such postures, to improve blood circulation in the body, or to relieve momentary muscle stiffness, by moving along the body and applying thermal stimulation to the painful area to improve blood flow.

[0003] Korean Patent Publication No. 10-2022-0072812 (published on June 2, 2022) discloses a conventional thermal therapy device. This conventional thermal therapy device includes an acupressure module that applies pressure to the user. The acupressure module includes a hinged member on one side and a swivel member that can be raised or lowered on the other side. An acupressure unit is provided on the upper surface of the other side of the swivel member to apply pressure to the user.

[0004] Additionally, a weight sensing unit having a predetermined length in the longitudinal and transverse directions is placed between the upper surface of the pivot member and the lower surface of the pressure member to detect a load applied by the user.

[0005] However, if the weight sensing unit is placed on the upper surface of the pivot member in this way, there is a problem in that it takes up a lot of installation space due to the length and width directions of the weight sensing unit.

[0006] In addition, when the swivel member is placed horizontally, the user's load applied through the pressure part is applied vertically to the weight sensing part, so accurate load measurement is possible. However, when the swivel member is raised or lowered, the user's load applied through the pressure part is applied to the weight sensing part at a predetermined incline, so there is also the problem that accurate load measurement is difficult.

[0007] Therefore, there is a need to develop technologies that can solve these problems.

[0008] (Patent Document 1) Korean Patent Publication No. 10-2022-0072812 (published on June 2, 2022)

[0009] The present invention is intended to solve the above problems, and an object of the present invention is to provide a pressurized rod capable of measuring a user's load, which can minimize installation space and accurately measure the load even when the pressurized member is raised or lowered.

[0010] 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.

[0011] According to one aspect of the present invention, a pressure rod capable of measuring a user's load is provided, including a pressure member that pressurizes a user, a load member on which the pressure member is disposed and which is provided with a rotating rod that rotates by a load applied through the pressure member, and a sensing member disposed on the load member and which measures the user's load using the rotational force of the rotating rod.

[0012] At this time, the load member may further include a support rod having a rotation axis so that the rotation rod rotates.

[0013] At this time, the sensing member is arranged on the support rod, and the rotating rod can convert the user's load applied along the height direction into a width direction load and transmit it to the sensing member.

[0014] At this time, the support rod may be provided with a receiving groove open on one side in the width direction so that the sensing member is placed therein, and the sensing member may be provided with a load application surface placed on one side in the width direction.

[0015] At this time, a first unit rod extending in the width direction may be provided on the upper side in the height direction of the rotating rod, and a second unit rod extending in the width direction may be provided on the lower side in the height direction of the rotating rod.

[0016] At this time, the pressing member may be arranged on one side of the first unit load in the width direction, and the second unit load may be provided with a pressing protrusion extending toward the other side in the width direction.

[0017] At this time, the pressing member may be arranged on the other side in the width direction of the first unit load, and the second unit load may be provided with a pressing protrusion extending toward one side in the width direction.

[0018] At this time, the pressurizing member is provided with a load application point to which the user's load is applied, and the load application point can be arranged at a predetermined distance apart from the height direction extension line of the rotation axis and one side in the width direction.

[0019] According to the above configuration, the pressure rod capable of measuring the user's load according to one aspect of the present invention eliminates the need to place the sensing member on the upper surface of the massage module since the sensing member is placed on the load member, thereby minimizing the space occupied by the sensing member inside the massage module, thereby enabling miniaturization of the massage module and improving the degree of freedom of layout when designing the interior of the massage module. In addition, when the user's load is applied to the pressure rod, the rotating rod on which the pressure rod is placed rotates in the width direction to transmit the load to the sensing member, thereby enabling accurate measurement of the user's load regardless of the rotation angle of the pressure rod.

[0020] The effects of the present invention are not limited to the effects described above, and should be understood to include all effects that can be inferred from the detailed description of the present invention or the composition of the invention described in the claims.

[0027] 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.

[0028] 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.

[0029] Therefore, the embodiments described in this specification and the configurations illustrated in the drawings correspond to a preferred embodiment of the present invention, and do not represent all of the technical ideas of the present invention, so there may be various equivalents and modified examples that can replace the configuration at the time of filing of the present invention.

[0030] In this specification, terms such as “include” or “have” are intended to describe the presence of a feature, number, step, operation, component, part or combination thereof described in the specification, but should be understood not to exclude in advance the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts or combinations thereof.

[0031] FIG. 1 is a perspective view of a pressurizing rod capable of measuring a user's load according to one embodiment of the present invention, and FIG. 2 is a front view of a pressurizing rod capable of measuring a user's load according to one embodiment of the present invention. Here, the X direction is a longitudinal direction (the same direction as the user's spinal alignment direction), the Y direction is a width direction, which is divided into one side and the other side in the width direction centered on the user's spine, and the Z direction is a height direction, which is a direction in which a pressurizing member rises or falls to adjust the degree of pressurizing the user's body. In order to clearly describe the present invention, parts that are not related to the description are omitted from the drawings.

[0032] As illustrated in FIGS. 1 and 2, a pressure rod (10) capable of measuring a user's load according to one embodiment of the present invention includes a pressure member (100) that presses a user, a load member (200) on which the pressure member (100) is disposed and which is provided with a rotating rod (210) that rotates by a load applied through the pressure member (100), and a detection member (300) that is disposed on the load member (200) and measures the user's load using the rotational force of the rotating rod (210).

[0033] This pressurized rod (10) can be mounted on a massage module described later, and the massage module can massage the spine while moving in the longitudinal direction (X) along the user's spine, and can provide a massage effect at an appropriate temperature depending on the massaged location by heating or cooling the pressurized member (100) through a separate control unit.

[0034] At this time, the pressurizing member (100) may be configured to provide a thermal steaming and massage effect to the user by using not only high temperature heat but also far infrared rays.

[0035] The pressure member (100) may be formed in a roller shape, but is not limited thereto, and various shapes and structures are possible as long as the pressure member (100) is configured to rotate while the massage module moves in the longitudinal direction (X).

[0036] In addition, when the pressure member (100) is formed of a material such as ceramic, far infrared rays are generated during the use of the massage module, 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.

[0037] At this time, the load member (200) is provided with a detection member (300) that detects the user's load. When the detection member (300) is placed on the load member (200) in this way, there is no need to place the detection member (300) on the upper surface of the massage module described later, so that the space occupied by the detection member (300) inside the massage module is minimized, enabling miniaturization of the massage module and improving the degree of freedom in layout when designing the inside of the massage module.

[0038] This load member (200) is equipped with a rotating rod (210) that rotates when a user's load is applied to the pressure member (100), and the detection member (300) measures the user's load using the rotational force of the rotating rod (210).

[0039] For example, a hinge axis extending along the width direction (Y) may be provided on one side of the pressurizing rod (10), and the pressurizing member (100) described above may be arranged on the other side. In this state, when the pressurizing rod (10) rotates, the pressurizing member (100) rises or falls in the height direction (Z), and the pressurizing force for pressing the user is adjusted according to the height direction (Z) position of the pressurizing member (100).

[0040] At this time, when a load is applied from the user through the pressure member (100), the rotary rod (210) rotates in the width direction (Y). That is, as illustrated in FIG. 2, when the pressure rod (10) is arranged parallel to the height direction (Z) (a state in which the pressure force for pressing the user is maximum), when the user's load is applied to the pressure member (100) in this state, the rotary rod (210) on which the pressure member (100) is arranged rotates in the width direction (Y), which is the left direction based on FIG. 2, to transmit the load to the detection member (300). With this configuration, the user's load can be accurately measured regardless of the rotation angle of the pressure rod (10).

[0041] As illustrated in FIGS. 1 and 2, the load member (200) may further include a support rod (220) provided with a rotation axis (220a) so that the rotation rod (210) rotates. That is, as described above, when a user's load is applied to the pressure member (100), the rotation rod (210) rotates around the rotation axis (220a) provided in the support rod (220).

[0042] The direction of this rotation axis (220a) varies depending on the rotation angle of the pressurizing rod (10). That is, when the pressurizing rod (10) is not rotated and the pressurizing rod (10) is arranged parallel to the longitudinal direction (X) (the rotation angle of the pressurizing rod (10) is 0 degrees), the rotation axis (220a) is arranged parallel to the height direction (Z), and when the pressurizing rod (10) is arranged parallel to the height direction (Z) (the rotation angle of the pressurizing rod (10) is 90 degrees), the rotation axis (220a) is arranged parallel to the longitudinal direction.

[0043] In addition, when the rotation angle of the pressurized rod (10) is greater than 0 degrees and less than 90 degrees, the rotation axis (220a) is arranged in a direction tangent to the circumference of a concentric circle centered on the hinge axis of the pressurized rod (10).

[0044] In this way, when the rotational axis (220a) is arranged as described above, regardless of the rotational angle of the pressurized rod (10), when a user load is applied, the rotational rod (210) on which the pressurized member (100) is arranged rotates in the width direction (Y) to transmit the load to the detection member (300), and the user's load can be accurately measured regardless of the rotational angle of the pressurized rod (10).

[0045] FIG. 3 is a front view of a pressurized rod capable of measuring a user's load according to one embodiment of the present invention, and is a drawing illustrating an operating state when a user's load is applied, and FIG. 4 is a drawing explaining that a user's load applied in the height direction to a pressurized rod capable of measuring a user's load according to one embodiment of the present invention is converted into a width direction load.

[0046] As shown in FIGS. 3 and 4, a sensing member (300) is placed on the support rod (220), and the rotating rod (210) can convert the user's load (W1) applied along the height direction (Z) into a width direction load (W2) and transmit it to the sensing member (300).

[0047] That is, since the user's load (W1) applied in the height direction (Z) is converted into a width direction load (W2) and transmitted to the detection member (300) by the rotational rod (210), the user's load can be accurately measured regardless of the rotational angle of the pressure rod (10).

[0048] FIG. 5 is a cross-sectional view of a pressurized rod capable of measuring a user's load according to one embodiment of the present invention.

[0049] As shown in Fig. 5, the support rod (220) is provided with a receiving groove (221) that is open on one side in the width direction (Y) so that a sensing member (300) is placed therein, and the sensing member (300) may be provided with a load application surface (310) that is placed on one side in the width direction (Y).

[0050] That is, the worker inserts and places the sensing member (300) in the width direction (Y) inside the receiving groove (221), and assembles it so that the load application surface (310) provided on the sensing member (300) is exposed on one side in the width direction (Y), and then, during the use of the pressurized rod (10), as the rotating rod (210) rotates (direction A) in the width direction (Y), the user's load (W1) is converted into a width direction load (W2) and transmitted to the load application surface (310), thereby enabling measurement of the user's load.

[0051] As illustrated in FIG. 5, a first unit rod (210') extending in the width direction (Y) may be provided on the upper side of the rotation rod (210) in the height direction (Z), and a second unit rod (210") extending in the width direction (Y) may be provided on the lower side of the rotation rod (210) in the height direction (Z).

[0052] At this time, the upper and lower sides in the height direction (Z) are distinguished with the rotation axis (220a) as the center, and the left side of the rotation axis (220a) may mean one side in the width direction (Y), and the right side of the rotation axis (220a) may mean the other side in the width direction (Y). That is, the first unit rod (210') may be arranged on the other side in the width direction (Y) with the rotation axis (220a) as the center, but may extend upward in the height direction (Z), and the second unit rod (210") may be arranged on one side in the width direction (Y) with the rotation axis (220a) as the center, but may extend downward in the height direction (Z).

[0053] In this way, when the rotary rod (210) is divided into a first unit rod (210') and a second unit rod (210") centered on the rotary axis (220a), the rotary rod (210) can rotate smoothly when a user load is applied, effectively transmitting the user load.

[0054] As illustrated in FIG. 5, a pressure member (100) may be arranged on one side in the width direction (Y) of the first unit load (210'), and a pressure projection (211) extending toward the other side in the width direction (Y) may be provided on the second unit load (210").

[0055] That is, when a user's load is applied to the pressure member (100), the user's load is transferred to the first unit load (210'), and the first unit load (210') and the second unit load (210") rotate around the rotation axis (220a) due to the load transferred in this manner, and when the second unit load (210") rotates, the pressure projection (211) transfers the user's load to the load application surface (310) of the detection member (300).

[0056] At this time, the pressure protrusion (211) may be extended to a sufficient length to be in contact with the load application surface (310) of the detection member (300). However, it is preferable that the pressure protrusion (211) be extended to a length that is sufficient to contact the load application surface (310) when no load is applied by the user, but does not pressurize the load application surface (310).

[0057] When the pressure projection (211) is placed in contact with the load application surface (310) in this way, when the user's load is applied, the rotation of the rotation rod (210) occurs, and through this, the user's load can be quickly transferred to the load application surface (310).

[0058] Alternatively, a pressure member (100) may be placed on the other side in the width direction (Y) of the first unit load (210'), and a pressure projection (211) extending toward one side in the width direction (Y) may be provided on the second unit load (210”).

[0059] That is, when a user's load is applied to the pressure member (100), the user's load is transferred to the first unit load (210'), and the first unit load (210') and the second unit load (210") rotate around the rotation axis (220a) due to the load transferred in this manner, and when the second unit load (210") rotates, the pressure protrusion (211) transfers the user's load to the load application surface (310) of the detection member (300). The detailed configuration of the pressure protrusion (211) is as described above.

[0060] As shown in FIGS. 3 and 4, the pressurizing member (100) is provided with a load application point (WP) to which a user's load is applied, and the load application point (WP) can be positioned at a predetermined distance apart from the extension line (EL) in the height direction (Z) of the rotation axis (220a) and one side in the width direction (Y).

[0061] As illustrated in FIG. 3, the pressure member (100) can be formed into a shape that is curved radially outward so that a specific location, such as an acupuncture point, can be pressed when the user is pressed, and as the pressure member (100) is formed into this shape, a load application point (WP) to which the user's load (W1) is applied is located at the upper end in the height direction (Z) of the pressure member (100).

[0062] As illustrated in FIG. 4, since the load application point (WP) is positioned at a predetermined distance (d) apart from the extension line (EL) in the height direction (Z) of the rotation axis (220a) and one side in the width direction (Y), when the user's load (W1) is applied, a moment having a size corresponding to the product of the user's load (W1) and the distance (d) is generated, and the rotation rod (210) rotates in the A direction through this moment, and the width direction load (W2) transmitted while the rotation rod (210) rotates is transmitted to the load application surface (310).

[0063] FIG. 6 is a perspective view of a massage module including a pressurized rod capable of measuring a user's load according to another embodiment of the present invention.

[0064] As illustrated in FIG. 6, according to another embodiment of the present invention, a massage module is provided, which includes a plurality of pressure rods (10) arranged along the width direction (Y), each of which includes a pressure member (100) that presses a user, a rod member (200) having a rotational rod (210) that is rotated by a load applied through the pressure member (100) and on which the pressure member (100) is arranged, and a detection member (300) that is arranged on the rod member (200) and measures a load of the user using the rotational force of the rotational rod (210).

[0065] These plurality of pressure rods (10) are arranged along the width direction (Y), and can be arranged to pressurize one side and the other side of the width direction (Y) with the user's spine as the center. Since the plurality of pressure rods (10) are arranged to pressurize one side and the other side of the width direction (Y) with the user's spine as the center, a massage effect can be provided by pressing acupressure points (for example, acupressure points according to the Foot-Taiyang Bladder Meridian) located on both sides along the user's spine.

[0066] At this time, the specific configuration of the load member (200) equipped with the rotary rod (210) and the detection member (300) that measures the user's load using the rotational force of the load member (200) is the same as the configuration described above, and since the detection member (300) is arranged on the load member (200), there is no need to arrange the detection member (300) on the upper surface of the massage module, so that the space occupied by the detection member (300) inside the massage module is minimized, enabling miniaturization of the massage module and improving the degree of freedom of layout when designing the inside of the massage module. In addition, when the user's load is applied to the pressure member (100), the rotation rod (210) on which the pressure member (100) is arranged rotates in the width direction (Y) to transmit the load to the detection member (300), so that the user's load can be accurately measured regardless of the rotation angle of the pressure rod (10).

[0067] These massage modules can massage the spine while moving in the longitudinal direction (X) along the user's spine. At this time, the massage module can be equipped with a transport unit having a transport motor member and a transport member so that the massage module pressurizes the user while moving in the longitudinal direction (X).

[0068] The transfer motor member is provided with a transfer shaft member that rotates when current is supplied, and the transfer member is connected to the transfer shaft member and transmits rotational force according to the rotation of the transfer shaft member to move the massage module.

[0069] The transport member is connected to the massage module and is used to transport the massage module in one or the other direction along the user's longitudinal direction (X) depending on the forward or reverse rotation of the transport motor member.

[0070] The transport member may be selectively used as a transport belt, transport chain, or transport rope, but is not limited thereto, and various means of transporting an object using the driving force of the transport motor member, such as a lead screw or a rack and pinion, may be used.

[0071] As described above, a hinge axis extending along the width direction (Y) may be provided on one side of the pressure rod (10), and the above-described pressure member (100) may be arranged on the other side. In this state, a drive unit (30) having a drive motor (31) may be provided in the massage module so that the pressure rod (10) rotates around the hinge axis. The control unit controls the operation of the drive motor (31) to adjust the height direction (Z) position of the pressure member, thereby adjusting the degree to which the pressure member presses the user.

[0072] Additionally, the massage module may be equipped with a base frame (21) to which a drive motor (31) is fixed. This enables stable fixation of the drive motor (31), and in this state, stable supply of driving force is enabled through the drive shaft member.

[0073] At this time, side frames (22) may also be provided on both sides of the width direction (Y) of the base frame (21). These side frames (22) are formed to extend along the height direction (Z) to reinforce the structural rigidity of the base frame (21), thereby enabling the user's load to be stably supported.

[0074] At this time, the base frame (21) may be provided with a hinge plate to which the hinge axis of the pressure rod (10) is fixed, and if configured in this way, stable support is possible even when a user's load is applied to the pressure rod (10).

[0075] These massage modules can be installed on a pad that supports the user's body. The pad may include a main mat used for the user's upper body and spine, and an auxiliary mat used for the user's lower body. Additionally, the pad may include a mounting portion for placing and supporting the main and auxiliary mats, as needed.

[0076] As shown in Fig. 6, the rotating rods (210) that are arranged opposite to each other along the width direction (Y) can be arranged so that the pressing member (100) rotates in a direction facing inward in the width direction (Y).

[0077] That is, as described above, when a user's load is applied to the pressure member (100), the rotational rod (210) on which the pressure member (100) is arranged rotates in the width direction (Y) to transmit the load to the detection member (300). At this time, it is important that the rotational direction of the rotational rod (210) is arranged to rotate in a direction facing inward in the width direction (Y).

[0078] At this time, the fact that the direction of rotation of the mutually opposed rotating rods (210) is in the direction facing inward in the width direction (Y) means that the rotating rods (210) rotate so that the distance between the pressing members (100) respectively disposed on the mutually opposed rotating rods (210) becomes closer.

[0079] Usually, when using a massage module, the user receives a massage in comfortable clothing. However, if the rotating rod (210) rotates in a direction facing outward in the width direction (Y) (a direction in which the distance between the pressure members (100) increases), the rotation of the rotating rod (210) may be restricted due to the material properties of the clothing worn by the user (particularly, a material with little elasticity), and this may reduce the accuracy of the user load measurement result. However, as described above, if the rotation directions of the mutually opposed rotating rods (210) rotate in a direction facing inward in the width direction (Y), accurate user load measurement is possible without being affected by the clothing worn by the user.

[0080] As illustrated in FIG. 6, each pressure member (100) further includes a heater (110) inserted into each pressure member (100) and a power line (120) supplying current to each heater (110), and each power line (120) can be installed in the pressure member (100) in a direction from the outside to the inside in the width direction (Y).

[0081] When each pressurizing member (100) is equipped with a heater (110), a massage effect by heat can be provided to the user during the massage process, thereby maximizing the massage effect. For example, the heater (110) may be a heater using a PTC (Positive Temperature Coefficient) element, but is not necessarily limited thereto, and any configuration that can provide a heat effect, such as a heating wire, a light bulb, or a surface heating element, may be used.

[0082] A power line (120) is connected to this heater (110) to supply current, and as described above, the rotary rod (210) rotates inwardly in the width direction (Y) during the use of the massage module. Therefore, if the power line (120) is installed in the pressure member (100) in a direction from the outside to the inside in the width direction (Y), interference can be prevented from occurring during the rotation of the rotary rod (210).

[0083] As illustrated in Fig. 6, a finishing surface (200a) extending along the height direction (Z) may be provided on the outer side in the width direction (Y) of the load member (200) that is arranged to face each other along the width direction (Y).

[0084] As described above, since the rotary rod (210) rotates inwardly in the width direction (Y) while the pressure member (100) is positioned inwardly in the width direction (Y), a finishing surface (200a) can be formed on the outer side in the width direction (Y). When the finishing surface (200a) is formed on the outer side in the width direction (Y), the degree of design freedom on the outer side in the width direction (Y) is improved during the design process of the massage module, and even when the pressure rod (10) operates while the massage module is inserted and positioned in the pad portion, interference with other parts can be prevented.

[0085] As described above, the pressure rod (10) capable of measuring the user's load according to one embodiment of the present invention eliminates the need to place the detection member (300) on the upper surface of the massage module since the detection member (300) is placed on the load member (200), thereby minimizing the space occupied by the detection member (300) inside the massage module, thereby enabling miniaturization of the massage module and improving the degree of freedom of layout when designing the interior of the massage module. In addition, when the user's load is applied to the pressure rod (100), the rotation rod (210) on which the pressure member (100) is placed rotates in the width direction (Y) to transmit the load to the detection member (300), thereby enabling accurate measurement of the user's load regardless of the rotation angle of the pressure rod (10).

[0086] Although one embodiment of the present invention has been described, 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.
