Description

Technical Field

[0001] This invention relates to massage devices, and more specifically, to a pressure bar capable of measuring user load. Background Technology

[0002] In the past, a spinal thermal massage device has been widely used to relieve acute or chronic pain in the muscles and nerve tissues of the spine caused by prolonged work in an inappropriate posture or habitual posture, as well as to improve blood circulation or relieve momentary muscle stiffness. This device moves along the body and applies heat 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 thermotherapy device. This conventional thermotherapy device includes an acupressure module for applying pressure to a user. The acupressure module has a swinging member, one side of which is hinged and fixed, while the other side rises or falls. The upper surface of the other side of the swinging member has an acupressure portion for applying pressure to the user.

[0004] In addition, in order to sense the load applied by the user, a weight sensing part is disposed between the upper surface of the swinging component and the lower surface of the acupressure part, the weight sensing part having a predetermined length in both the length and width directions.

[0005] However, when the weight sensing unit is disposed on the upper surface of the swinging component, the weight sensing unit occupies a large installation space due to its length in both the length and width directions, which is a problem.

[0006] Furthermore, when the swinging member is horizontally positioned, the user load applied by the acupressure point is applied vertically to the weight sensing unit, thus allowing for accurate load measurement. However, when the swinging member is in a raised or lowered state, the user load applied by the acupressure point is applied with a predetermined tilt relative to the weight sensing unit, making it difficult to accurately measure the load.

[0007] Therefore, there is an urgent need to develop technologies that can solve the above problems.

[0008] Existing technical documents Patent documents (Patent Document 1) Korean Patent Publication No. 10-2022-0072812 (Published on June 2, 2022) Summary of the Invention The technical problem that the invention aims to solve The present invention aims to solve the above-mentioned problems. The purpose of the present invention is to provide a pressure rod that can measure user load, which can minimize the installation space and accurately measure the load even when the pressure component is in the raised or lowered state.

[0009] The subject matter of this invention is not limited to the subject matter described above, and other subject matters not mentioned can be clearly understood by those skilled in the art based on the following description.

[0010] means for solving problems According to one embodiment of the present invention, a pressure rod for measuring user load is provided, comprising: a pressure member for applying pressure to a user; a rod member having the pressure member disposed thereon and having a rotating rod that rotates due to the load applied by the pressure member; and a sensing member disposed thereon and measuring the user load using the rotational force of the rotating rod.

[0011] At this time, the rod component may also include a support rod having a rotation axis to rotate the rotary rod.

[0012] At this time, the support rod is equipped with the sensing component, and the rotating rod can convert the user load applied in the height direction into a load in the width direction and transmit it to the sensing component.

[0013] At this time, the support rod may have a receiving groove that opens toward one side in the width direction to configure the sensing component, and the sensing component may have a load application surface configured on one side in the width direction.

[0014] At this time, the upper side of the slewing rod in the height direction may have a first unit rod extending toward the other side in the width direction, and the lower side of the slewing rod in the height direction may have a second unit rod extending toward one side in the width direction.

[0015] At this time, the pressurizing component can be arranged on one side of the width direction of the first unit rod, and the second unit rod can have a pressurizing protrusion extending toward the other side of the width direction.

[0016] At this time, the pressurizing member can be arranged on the other side of the width direction of the first unit rod, and the second unit rod can have a pressurizing protrusion extending toward one side of the width direction.

[0017] At this time, the pressurizing component may have a load application point for the user to apply load, and the load application point may be configured at a predetermined distance from the extension line of the height direction of the rotation axis on one side of the width direction.

[0018] The effects of the invention According to the above configuration, the pressure rod for measuring user load according to one aspect of the present invention, since the sensing element is disposed on the rod member, it is not necessary to place the sensing element on the upper surface of the massage module. This minimizes the space occupied by the sensing element inside the massage module, thereby achieving miniaturization of the massage module and increasing the layout freedom during the internal design of the massage module. Furthermore, when a user load is applied to the pressure rod, the rotating rod on which the pressure rod is disposed rotates in the width direction and transmits the load to the sensing element, thus enabling accurate measurement of the user load regardless of the rotation angle of the pressure rod.

[0019] The effects of the present invention are not limited to those described above, but should be understood to include all effects that can be derived from the detailed description of the invention or the inventive structure described in the claims. Attached Figure Description

[0026] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings to enable those skilled in the art to readily implement the invention. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. For clarity, parts irrelevant to the description have been omitted from the drawings, and identical or similar elements are referred to by the same reference numerals throughout the specification.

[0027] The words and terms used in this specification and claims should not be construed as limited to their ordinary or dictionary meaning, but should be interpreted as meanings and concepts consistent with the technical idea of ​​this invention, in accordance with the principle that the inventors define terms and concepts in order to best illustrate their invention.

[0028] Therefore, the embodiments described in this specification and the configurations shown in the accompanying drawings correspond only to a preferred embodiment of the present invention and do not represent all the technical ideas of the present invention. Therefore, at the time of application of this invention, there may be various equivalents and modifications that can replace them.

[0029] In this specification, terms such as “comprising” or “having” are intended to describe the presence of features, figures, steps, actions, constituent elements, components or combinations thereof described in the specification, and should not be construed as excluding the existence or additional possibilities of one or more other features, figures, steps, actions, constituent elements, components or combinations thereof.

[0030] Figure 1 This is a perspective view of a pressure rod capable of measuring user load according to an embodiment of the present invention. Figure 2 This is a front view of a pressure rod capable of measuring user load according to an embodiment of the present invention. Here, the X direction is the length direction (the same direction as the user's spine), the Y direction is the width direction, divided into one side and the other side of the width direction with the user's spine as the center, and the Z direction is the height direction, the direction in which the pressure member is raised or lowered to adjust the degree of pressure on the user's body. For the sake of clarity, parts unrelated to the description are omitted in the drawings.

[0031] like Figure 1 and Figure 2 As shown, a pressure rod 10 capable of measuring user load according to an embodiment of the present invention includes: a pressure member 100 for applying pressure to a user; a rod member 200 disposed thereon and having a rotary rod 210 that rotates due to the load applied by the pressure member 100; and a sensing member 300 disposed thereon and measuring the user's load using the rotational force of the rotary rod 210.

[0032] The pressure rod 10 can be installed in the massage module described later. The massage module can move along the user's spine in the length direction X and massage the spine. The pressure rod 100 can be heated or cooled by a separate control unit to provide a massage effect at an appropriate temperature according to the massage position.

[0033] At this time, the pressurizing component 100 can also be configured to provide the user with thermal therapy and massage effects by using high temperature heat and far-infrared rays.

[0034] The pressure-applying component 100 can be made of a roller, but is not limited to this. As long as the pressure-applying component 100 can rotate during the movement of the massage module along the length direction X, it can adopt various shapes and structures.

[0035] Furthermore, when the pressure component 100 is made of a material such as ceramic, it can generate far-infrared rays during the use of the massage module, thereby improving the massage effect. However, it is not limited to this material. As long as it can transfer heat to the user's body to provide a massage effect, it can also be made of other materials.

[0036] At this time, the rod member 200 has a sensing member 300 for sensing user load. Thus, when the sensing member 300 is disposed on the rod member 200, it is not necessary to place the sensing member 300 on the upper surface of the massage module described later. This minimizes the space occupied by the sensing member 300 inside the massage module, thereby achieving miniaturization of the massage module and increasing the layout freedom when designing the internal layout of the massage module.

[0037] The rod component 200 has a rotating rod 210 that rotates when a user load is applied to the pressurizing component 100, and the sensing component 300 uses the rotational force of the rotating rod 210 to measure the user load.

[0038] For example, one side of the pressure rod 10 may have a hinge shaft extending along the width direction Y, and the other side may be provided with the pressure member 100. In this state, when the pressure rod 10 rotates, the pressure member 100 rises or falls along the height direction Z, and the pressure applied to the user is adjusted according to the position of the pressure member 100 in the height direction Z.

[0039] At this time, when the user applies a load through the pressurizing component 100, the rotating rod 210 rotates along the width direction Y. That is, as Figure 2 As shown, the explanation is based on the state in which the pressure rod 10 is arranged parallel to the height direction Z (the state with the maximum pressure applied to the user). In this state, when the user load is applied to the pressure member 100, the rotating rod 210 of the pressure member 100 is positioned to... Figure 2 The load is transferred to the sensing component 300 by rotating to the left (width direction Y) as a reference. When configured in this way, the user load can be accurately measured without being affected by the rotation angle of the pressure rod 10.

[0040] like Figure 1 and Figure 2As shown, the rod component 200 may further include a support rod 220 having a rotation axis 220a to rotate the rotary rod 210. That is, as previously described, when a user load is applied to the pressurizing component 100, the rotary rod 210 rotates about the rotation axis 220a provided on the support rod 220.

[0041] The direction of the rotation axis 220a changes according to the rotation angle of the pressure rod 10. That is, when the pressure rod 10 is not rotating, i.e., when the pressure rod 10 is arranged parallel to the length direction X (the rotation angle of the pressure rod 10 is 0 degrees), the rotation axis 220a is arranged parallel to the height direction Z; when the pressure rod 10 is arranged parallel to the height direction Z (the rotation angle of the pressure rod 10 is 90 degrees), the rotation axis 220a is arranged parallel to the length direction.

[0042] Furthermore, when the rotation angle of the pressure rod 10 is greater than 0 degrees and less than 90 degrees, the rotation axis 220a is arranged in a direction tangent to a concentric circle centered on the hinge axis of the pressure rod 10.

[0043] Thus, even if the pressure rod 10 has any rotation angle, when the rotating shaft 220a is configured as described above, when a user load is applied, the rotating rod 210 with the pressure member 100 rotates in the width direction Y and transmits the load to the sensing member 300, thereby enabling accurate measurement of the user load regardless of the rotation angle of the pressure rod 10.

[0044] Figure 3 To show a front view of a pressure rod capable of measuring user load according to an embodiment of the present invention, and a diagram showing the operating state when a user load is applied, Figure 4 This diagram illustrates how a user load applied along the height direction in a pressure bar that can measure user load according to an embodiment of the present invention is converted into a load in the width direction.

[0045] like Figure 3 and Figure 4 As shown, the support rod 220 is equipped with the sensing component 300, and the rotating rod 210 can convert the user load W1 applied in the height direction Z into a width direction load W2 and transmit it to the sensing component 300.

[0046] That is, due to the presence of the rotating rod 210, the user load W1 applied along the height direction Z is converted into a width direction load W2 and transmitted to the sensing component 300, thus enabling accurate measurement of the user load regardless of the rotation angle of the pressure rod 10.

[0047] Figure 5A cross-sectional view is shown for a pressure bar capable of measuring user load according to an embodiment of the present invention.

[0048] like Figure 5 As shown, the support rod 220 may have a receiving groove 221 that opens toward the Y side of the width direction to accommodate the sensing component 300. The sensing component 300 may have a load application surface 310 that is disposed on the Y side of the width direction.

[0049] That is, the operator inserts the sensing component 300 into the receiving groove 221 along the width direction Y and assembles it so that the load application surface 310 of the sensing component 300 is exposed on the side of the width direction Y. Then, during the use of the pressure rod 10, as the rotating rod 210 rotates along the width direction Y (direction A), the user load W1 is converted into a width direction load W2 and transmitted to the load application surface 310, thereby enabling the measurement of the user load.

[0050] like Figure 5 As shown, the upper side of the rotating rod 210 in the height direction Z may have a first unit rod 210' extending toward the other side in the width direction Y, and the lower side of the rotating rod 210 in the height direction Z may have a second unit rod 210", extending toward the side in the width direction Y.

[0051] At this time, with Figure 5 Centered on the rotation axis 220a, the upper and lower sides in the height direction Z can be distinguished. The left side of the rotation axis 220a can represent one side in the width direction Y, and the right side of the rotation axis 220a can represent the other side in the width direction Y. That is, the first unit rod 210' is arranged on the other side in the width direction Y centered on the rotation axis 220a and extends upward in the height direction Z, while the second unit rod 210" is arranged on one side in the width direction Y centered on the rotation axis 220a and extends downward in the height direction Z.

[0052] Thus, when the rotary rod 210 is divided into a first unit rod 210' and a second unit rod 210" with the rotation axis 220a as the center, the rotary rod 210 can rotate smoothly and effectively transmit the user load when the user load is applied.

[0053] like Figure 5 As shown, the pressure member 100 is disposed on one side of the width direction Y of the first unit rod 210', and the second unit rod 210" may have a pressure protrusion 211 extending toward the other side of the width direction Y.

[0054] That is, when a user load is applied to the pressurizing member 100, the user load is transmitted to the first unit rod 210', and the first unit rod 210' and the second unit rod 210" rotate about the rotation axis 220a by the load transmitted in this way. When the second unit rod 210" rotates, the pressurizing protrusion 211 transmits the user load to the load application surface 310 of the sensing member 300.

[0055] At this time, the pressure protrusion 211 may be extended to a length sufficient to contact the load application surface 310 of the sensing element 300. However, it is preferable that, in the absence of a user load, the pressure protrusion 211 contacts the load application surface 310, but is only extended to a length that does not apply pressure to the load application surface 310.

[0056] Thus, when the pressure protrusion 211 is configured to contact the load application surface 310, the rotary rod 210 rotates when a user load is applied, thereby enabling the user load to be quickly transferred to the load application surface 310.

[0057] Alternatively, the pressurizing member 100 may be configured on the other side of the width direction Y of the first unit rod 210', and the second unit rod 210" may have a pressurizing protrusion 211 extending toward the width direction Y side.

[0058] That is, when a user load is applied to the pressurizing component 100, the user load is transmitted to the first unit rod 210', and the first unit rod 210' and the second unit rod 210" rotate about the rotation axis 220a by the load transmitted in this way. When the second unit rod 210" rotates, the pressurizing protrusion 211 transmits the user load to the load application surface 310 of the sensing component 300. The detailed configuration of the pressurizing protrusion 211 is as described above.

[0059] like Figure 3 and Figure 4 As shown, the pressurizing component 100 has a load application point WP for the user to apply load, and the load application point WP can be configured at a predetermined distance from the extension line EL of the height direction Z of the rotating shaft 220a on the width direction Y side.

[0060] like Figure 3 As shown, the pressure member 100 can be formed into a shape that bends outward in the radial direction to apply pressure to specific locations such as acupoints when applying pressure to the user, and as the pressure member 100 forms this shape, a load application point WP for applying the user load W1 is formed at the upper end of the pressure member 100 in the height direction Z.

[0061] like Figure 4As shown, since the load application point WP and the extension line EL of the height direction Z of the rotation axis 220a are arranged at a predetermined distance d on the width direction Y side, when the user load W1 is applied, a torque is generated with a magnitude corresponding to the product of the user load W1 and the distance d. This torque causes the rotary rod 210 to rotate in the A direction, and the width direction load W2 transmitted as the rotary rod 210 rotates is transmitted to the load application surface 310.

[0062] Figure 6 A perspective view of a massage module including a pressure bar capable of measuring user load, according to another embodiment of the present invention.

[0063] like Figure 6 As shown, 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 pressure rod 10 includes: a pressure member 100 for applying pressure to a user; a rod member 200 disposed on the pressure member 100 and having a rotary rod 210 that rotates by the load applied by the pressure member 100; and a sensing member 300 disposed on the rod member 200 and measuring the user's load using the rotational force of the rotary rod 210.

[0064] The plurality of pressure rods 10 are arranged along the width direction Y, and can be configured to apply pressure to one side and the other side of the width direction Y centered on the user's spine. Since the plurality of pressure rods 10 are configured to apply pressure to one side and the other side of the width direction Y centered on the user's spine, a massage effect can be provided while applying pressure to acupoints distributed along both sides of the user's spine (e.g., acupoints according to the Bladder Meridian of Foot Taiyang).

[0065] At this time, the specific configuration of the rod member 200 with the rotating rod 210 and the sensing member 300 that measures the user load using the rotational force of the rod member 200 is the same as described above. Since the sensing member 300 is disposed on the rod member 200, it is not necessary to place the sensing member 300 on the upper surface of the massage module. This minimizes the space occupied by the sensing member 300 inside the massage module, thereby achieving miniaturization of the massage module and increasing the layout freedom during the internal design of the massage module. Furthermore, when a user load is applied to the pressure member 100, the rotating rod 210 with the pressure member 100 rotates along the width direction Y and transmits the load to the sensing member 300. Therefore, the user load can be accurately measured without being affected by the rotation angle of the pressure rod 10.

[0066] The massage module can move along the user's spine in the length direction X and massage the spine. At this time, the massage module may have a transmission unit, which includes a transmission motor component and a transmission component, to move the massage module along the length direction X and apply pressure to the user.

[0067] The transmission motor component has a transmission shaft component that rotates when current is supplied. The transmission component is connected to the transmission shaft component and transmits its rotational force to move the massage module as the transmission shaft component rotates.

[0068] The transmission component is connected to the massage module and is used to transmit the massage module to one side or the other side along the user's length direction X, depending on the forward or reverse rotation of the transmission motor component.

[0069] The conveying component can selectively employ a conveyor belt, conveyor chain, or conveyor rope, but is not limited to these. It can also employ various methods of conveying objects using the driving force of the conveying motor component, such as using a lead screw or a rack and pinion.

[0070] As previously described, one side of the pressure rod 10 may have a hinge axis extending along the width direction Y, and the other side may be equipped with the pressure member 100. In this state, to allow the pressure rod 10 to rotate around the hinge axis, the massage module may have a drive unit 30, which includes a drive motor 31. The control unit adjusts the position of the pressure member in the height direction Z by controlling the operation of the drive motor 31, thereby adjusting the degree of pressure applied to the user by the pressure member.

[0071] Furthermore, the massage module may also have a base frame 21, to which the drive motor 31 is fixed. This allows for stable fixing of the drive motor 31, and in this state, a stable driving force can be supplied via the drive shaft component.

[0072] At this time, the base frame 21 may also have side frames 22 on both sides in the width direction Y. The side frames 22 extend in the height direction Z and can stably support the user load by enhancing the structural rigidity of the base frame 21.

[0073] At this time, the base frame 21 may have a hinge plate, and the hinge axis of the pressure rod 10 is fixed to the hinge plate. When configured in this way, stable support can be achieved even if the user load is applied to the pressure rod 10.

[0074] The massage module can be installed on a pad that supports the user's body. The pad may include a main pad and an auxiliary pad; the main pad is for the user's upper body and spine, and the auxiliary pad is for the user's lower body. Additionally, if needed, a support portion may be included for placing and supporting the main pad and the auxiliary pad.

[0075] like Figure 6 As shown, the rotary rod 210, which is arranged opposite to each other along the width direction Y, can be configured to rotate the pressurizing member 100 toward the inside of the width direction Y.

[0076] That is, as mentioned above, when a user load is applied to the pressurizing member 100, the rotary rod 210 of the pressurizing member 100 rotates in the width direction Y and transmits the load to the sensing member 300. At this time, it is important to configure the rotary rod 210 to rotate in the direction toward the inside of the width direction Y.

[0077] At this time, the rotation direction of the relatively arranged rotary rods 210 is towards the inside of the width direction Y, which means that when the rotary rods 210 rotate, the distance between the pressure members 100 respectively arranged on the relatively arranged rotary rods 210 decreases.

[0078] Typically, when using the massage module, the user wears comfortable clothing to receive the massage. If the rotary rod 210 rotates in a direction outward in the width direction Y (i.e., in a direction that increases the distance between the pressure components 100), the rotation of the rotary rod 210 may be restricted due to the material properties of the user's clothing (especially materials with low elasticity), thereby reducing the accuracy of the user load measurement results. However, as mentioned above, when the relatively configured rotary rod 210 rotates in a direction inward in the width direction Y, the user load can be accurately measured without being affected by the user's clothing.

[0079] like Figure 6 As shown, it may also include heaters 110 respectively inserted into each pressurizing component 100, and power lines 120 supplying current to each heater 110. Each power line 120 may be arranged in the pressurizing component 100 in a direction from the outer side to the inner side in the width direction Y.

[0080] When each of the pressurizing components 100 has a heater 110, the massage effect can be maximized because it can provide a warm massage effect to the user during the massage process. For example, the heater 110 can be a heater using a PTC (Positive Temperature Coefficient) element, but it is not limited to this. Any component that can provide a warm effect can be used, such as a heating wire, a light bulb, or a surface heating element.

[0081] The heater 110 is connected to the power cord 120 to supply current, and as previously mentioned, during the use of the massage module, the rotary rod 210 rotates inward along the width direction Y. Therefore, when the power cord 120 is arranged on the pressure member 100 in the direction from the outer side to the inner side of the width direction Y, interference can be prevented during the rotation of the rotary rod 210.

[0082] like Figure 6 As shown, the outer side of the rod member 200 arranged opposite each other in the width direction Y may have a closed surface 200a extending in the height direction Z.

[0083] As previously described, when the pressure member 100 is positioned inside the width direction Y, the rotary rod 210 rotates inside the width direction Y, thus forming the closed surface 200a outside the width direction Y. When the closed surface 200a is formed outside the width direction Y, the design freedom of the outside of the width direction Y during the design of the massage module can be improved. Even when the pressure rod 10 moves while the massage module is inserted into the pad, interference with other components can be prevented.

[0084] As previously described, in the pressure rod 10 for measuring user load according to an embodiment of the present invention, since the sensing component 300 is disposed on the rod component 200, it is not necessary to place the sensing component 300 on the upper surface of the massage module. This minimizes the space occupied by the sensing component 300 within the massage module, thereby achieving miniaturization of the massage module and increasing the layout freedom during internal design. Furthermore, when a user load is applied to the pressure component 100, the rotating rod 210, on which the pressure component 100 is disposed, rotates along the width direction Y and transmits the load to the sensing component 300. Therefore, the user load can be accurately measured regardless of the rotation angle of the pressure rod 10.

[0085] Although one embodiment of the present invention has been described, the technical concept of the present invention is not limited to the embodiments disclosed in this specification. Those skilled in the art to which this invention pertains can easily propose other embodiments within the same technical concept by adding, changing, deleting, or supplementing constituent elements, based on an understanding of the technical concept of the present invention. These embodiments should also fall within the technical concept scope of the present invention.
