Description

Technical Field

[0001] The present invention relates to a massage ball, and more particularly to a massage ball having a clip component. Background Art

[0002] At present, spinal heating massage devices are widely used to relieve acute or chronic pain in the muscles and nerve tissues of the spine caused by long-term work in an incorrect posture or getting used to such a posture, and move along the body parts and apply warm stimulation to the painful parts to improve the body's blood circulation or eliminate temporary muscle soreness, thereby improving blood flow.

[0003] This spinal warming massage device is provided with a heatable massage ball to apply pressure to the user and stimulate through heat. A positive temperature coefficient heater (PTC heater) is provided at the center of the massage ball, and the PTC heater heats up when an electric current is applied.

[0004] In Korean Patent Gazette No. 1711030 (authorized on February 22, 2017), a conventional PTC heater is disclosed. This PTC heater is provided with a heating tube installed with a PTC component inside to transfer heat to the outside, and a plurality of heating tubes are provided to be combined by a combination protrusion and a combination groove portion in a state where the PTC component is arranged inside.

[0005] However, when arranged in the manner as described above, there is a problem that during the transfer of heat generated from the PTC assembly through the heating pipe, thermal expansion occurs in the heating pipe, and a gap is formed between the PTC assembly and the heating pipe by this thermal expansion, so that heat transfer performance is reduced.

[0006] In addition, there is a problem that the coupling force between the coupling protrusion and the coupling groove portion is reduced due to thermal expansion in the heating tube, so that the coupling state of the plurality of heating tubes is unstable.

[0007] Therefore, there is a need to develop a technology that can solve this problem.

[0060] The embodiments of the present invention are described in detail below with reference to the accompanying drawings so that a person skilled in the art can easily implement the present invention. The present invention can be embodied in a variety of different forms and is not limited to the embodiments described herein. In order to clearly illustrate the present invention, in the accompanying drawings, parts not related to the description of the embodiments are omitted, and the same reference numerals are given to the same or similar components throughout the specification.

[0061] The words and terms used in this specification and claims should not be limited to the usual or dictionary meanings, but are intended to explain the invention in the best way. Based on the principle that designers can define terms and concepts, they should be interpreted as meanings and concepts that are consistent with the technical ideas of the invention.

[0062] Therefore, the embodiments described in this specification and the structures shown in the drawings belong to a preferred embodiment of the present invention and do not represent the technical ideas of the present invention. Therefore, the structure may be replaced by various equivalents and modifications before submitting the present invention.

[0063] The terms "including" or "having" in this specification are used to illustrate the existence of the features, numbers, steps, actions, constituent elements, components or combinations thereof recorded in the specification, and do not preclude the existence or other possibilities of one or more other features, numbers, steps, actions, constituent elements, components or combinations thereof.

[0064] Figure 11 is a perspective view showing an assembled state of a massage ball with a clip member according to an embodiment of the present invention. Figure 2 1 is a perspective view showing a state where the outer cover member of a massage ball having a clip member according to an embodiment of the present invention is separated. Figure 3 1 is a perspective view showing a state in which a heating component of a massage ball with a clip component is combined with a clip component according to an embodiment of the present invention. Figure 4 The present invention is a front view showing a state where a heating component of a massage ball with a clip component is combined with a clip component. The a direction is the axial direction, and the r direction is the radial direction. In the accompanying drawings, parts not related to the description are omitted in order to more clearly illustrate the present invention.

[0065] like Figures 1 to 4 As shown, a massage ball with a clip component according to an embodiment of the present invention is a massage ball 10 that applies pressure to a user and provides a warm massage effect. The massage ball 10 includes a heating component 100, and the heating component 100 includes: a heater 110; a first inner cover 120, which is arranged on one side of the radial direction r to wrap the heater 110; and a second inner cover 130, which is arranged on the other side of the radial direction r to wrap the heater 110.

[0066] At this time, the massage ball 10 can be combined with a support arm configured in the warm massage device, and the support arm can be configured on the base of the massage device. The support arm can be set to rotate at a specified angle during the warm massage process. Any side plate of the first side plate 400 or the second side plate 500 described later can be combined with the support arm. Since the heater 110 is fixedly combined with this side plate, during the process of applying pressure to the user, the massage ball 10 can not only stably support the user's body, but also stably supply current to the heater 110.

[0067] The massage ball 10 may be provided with a power cord 20 for supplying current, and when current is supplied to the heater 110 through the power cord 20, the heater 110 may generate heat. The heater 110 may be a PTC heater, but is not limited thereto, and may be other structures such as a hot wire as long as it is a structure capable of generating heat.

[0068] At this time, the massage ball 10 includes: a clip part 200 for fixing the first inner cover 120 and the second inner cover 130; and an outer cover part 300 rotatably arranged on the outer surface of the first inner cover 120 and the second inner cover 130. Such an outer cover part 300 can be made of an elastic material to reduce the pain caused by pressure during the process of the massage ball 10 applying pressure to the user during the warm massage. As an example, the outer cover part 300 can be made of a silicon material.

[0069] The inner surface of the outer cover part 300 may be provided with an insert 310. The insert 310 may be made of an aluminum material having high heat transfer performance, so that the heat transferred by the heat generating component 100 can be smoothly transferred to the outer cover part 300, but the present invention is not limited thereto. Any material may be used as long as it has a structure having high heat transfer performance. The insert 310 may be provided as a whole by an insert injection molding method during the process of injection molding the outer cover part 300.

[0070] In addition, the insert 310 can be configured to extend from one end of the axial direction a of the outer cover part 300 to the other end so that it can support the inner surface of the outer cover part 300 while ensuring structural stability, thereby not only can the outer cover part 300 be easily assembled during the manufacturing process of the massage ball 10, but even if the user's load is applied to the massage ball 10 during the warm massage process, the load can be stably supported.

[0071] Meanwhile, a sliding surface may be provided on the inner surface of the insert 310 , and when the sliding surface is provided as described above, the outer cover member 300 may be smoothly rotated.

[0072] That is, as described above, in a state where the clip part 200 for fixing the first inner cover 120 and the second inner cover 130 is provided, wherein the first inner cover 120 is arranged on one side in the radial direction r to wrap the heater 110, and the second inner cover 130 is arranged on the other side in the radial direction r to wrap the heater 110, since the outer cover part 300 is rotatably arranged on the outer surfaces of the first inner cover 120 and the second inner cover 130, during the process in which the heat generated in the heater 110 is transferred through the first inner cover 120 and the second inner cover 130, even if thermal expansion occurs in the first inner cover 120 and the second inner cover 130, sufficient heat can be transferred to the user by preventing the heat transfer performance from being reduced, and the combined state of the first inner cover 120 and the second inner cover 130 can be stably maintained.

[0073] Figure 5 1 is a perspective view showing a clip component of a massage ball provided with a clip component according to an embodiment of the present invention. Figure 6 This is a cross-sectional view showing a state in which a heat generating component and a clip component of a massage ball with a clip component according to an embodiment of the present invention are coupled.

[0074] like Figure 5 and Figure 6 As shown, the clip component 200 includes a main body 210 and a pair of legs 220 , which are extended from the main body 210 along the axial direction a. Any one of the legs 220 can be fixed to the first inner cover 120 , and the other leg 220 can be fixed to the second inner cover 130 .

[0075] At this time, the pair of legs 220 may be configured to be elastically deformed outward along the radial direction r with the main body 210 as the center. When configured as described above, the pair of legs 220 are elastically deformed during the process of fixing the clip member 200 to the first inner cover 120 and the second inner cover 130, and after the pair of legs 220 are fixed, the elastic restoring force of the pair of legs 220 is applied to the first inner cover 120 and the second inner cover 130, so that the combined state of the first inner cover 120 and the second inner cover 130 can be stably maintained.

[0076] like Figure 4 As shown, the first inner cover 120 may be provided with a first insertion hole 121 for inserting and supporting any one leg 220 of the pair of legs 220 , and the second inner cover 130 may be provided with a second insertion hole 131 for inserting and supporting the other leg 220 of the pair of legs 220 .

[0077] That is, the operator can simply assemble by the following assembly method: when the clip component 200 is arranged on the axial side a of the heat generating component 100, any one leg 220 of the pair of legs 220 is inserted into the first insertion hole 121 and the other leg 220 of the pair of legs 220 is inserted into the second insertion hole 131.

[0078] In addition, the heat generated in the heater 110 moves through the first inner cover 120 and the second inner cover 130 in a conductive manner, and when the first insertion hole 121 and the second insertion hole 131 are respectively provided in the first inner cover 120 and the second inner cover 130, an air layer is formed inside the first insertion hole 121 and the second insertion hole 131, so the heat moved by the conductive method moves only to other parts where the first insertion hole 121 and the second insertion hole 131 are not formed. This is because heat flows in a direction with less resistance. When arranged in the manner as described above, the outer cover part 300 can be quickly heated by the first inner cover 120 and the second inner cover 130.

[0079] Figure 7 This is a cross-sectional view showing a modified example of a state in which a heat generating member and a clip member of a massage ball with a clip member according to an embodiment of the present invention are coupled.

[0080] like Figure 7 As shown, the inner surfaces of the first insertion hole 121 and the second insertion hole 131 may be respectively provided with mounting grooves SH formed inward in the radial direction r so as to respectively mount and configure the leg portions 220 .

[0081] As described above, the operator assembles in the following manner: when the clip component 200 is arranged on the axial side a of the heat-generating component 100, any one leg 220 of the pair of legs 220 is inserted into the first insertion hole 121 and the other leg 220 of the pair of legs 220 is inserted into the second insertion hole 131, and when the inner surfaces of the first insertion hole 121 and the second insertion hole 131 are respectively provided with mounting grooves SH formed inward in the radial direction r, when the pair of legs 220 are respectively installed in the mounting grooves SH, the elastic restoring force of the pair of legs 220 is applied to the mounting grooves SH, so that the combination state of the first inner cover 120 and the second inner cover 130 can be stably maintained.

[0082] like Figure 6 As shown, the main body 210 may be provided with a heat transfer surface 211 that is bent along the axial direction a.

[0083] As described above, when the heat transfer surface 211 is provided in the body 210, the heat generated by the heater 110 is transferred to the body 210, and the heat transferred to the body 210 is transferred to the first inner cover 120 and the second inner cover 130, so that the heat can be smoothly transferred by conduction.

[0084] To this end, the heat transfer surface 211 can be configured to be in thermal contact with the heater 110, and when arranged in the manner described above, the heat generated by the heater 110 can be quickly transferred to the first inner cover 120 and the second inner cover 130 through the body 210. In addition, when the heat transfer surface 211 is bent along the axial direction a, the heat transfer surface 211 can be configured to be easily in thermal contact with the heater 110 during the process of the operator assembling the clip member 200, so that stable heat transfer can be performed.

[0085] like Figure 6 As shown, the pair of legs 220 may be respectively provided with guide ribs 221 extending outward in the radial direction r.

[0086] As described above, the operator assembles in the following manner: with the clip member 200 disposed on one side of the axial direction a of the heat generating component 100 , one of the pair of legs 220 is inserted into the first insertion hole 121 and the other of the pair of legs 220 is inserted into the second insertion hole 131 .

[0087] In this case, when a pair of legs 220 are respectively provided with guide ribs 221 extending outward in the radial direction r, during the assembly process of the clamp component 200, the pair of legs 220 are easily elastically deformed outward in the radial direction r by the guide ribs 221, so that the clamp component 200 can be easily assembled.

[0088] Figure 81 is a perspective view showing an exploded state of a massage ball with a clip member according to an embodiment of the present invention. Fig. 9 yes Figure 1 The cross-sectional view of part Ⅰ-Ⅰ, Fig.10 yes Figure 1 The cross-sectional view of the Ⅱ-Ⅱ part, Fig.11 This is a front view showing a first side plate and a second side plate of a massage ball provided with a clip member according to an embodiment of the present invention.

[0089] like Figures 8 to 11 As shown, a first side plate 400 and a second side plate 500 fixedly supported on the heat-generating component 100 are respectively provided on one side and the other side of the axial direction a of the heat-generating component 100, and the inner surface of at least one of the first side plate 400 and the second side plate 500 may be provided with a first accommodating groove AH1 extending along the axial direction a.

[0090] A fastening member 30 may be provided to couple such first and second side plates 400 and 500 to one and the other sides of the first and second inner covers 120 and 130 in the axial direction a, respectively.

[0091] As described above, when the first side plate 400 and the second side plate 500 are provided, even if the outer cover member 300 relatively rotates while the heat generating component 100 is fixed and does not rotate, the outer cover member 300 can be prevented from being detached in the axial direction a.

[0092] An air layer can be formed inside the first accommodating groove AH1. When configured as described above, the movement of heat generated in the heat-generating component 100 is blocked by the air layer inside the first accommodating groove AH1 and is effectively prevented from being released to the outside through the first side plate 400 and the second side plate 500, thereby minimizing heat loss.

[0093] like Figures 8 to 11 As shown, a first supporting rib SR1 may be provided on an inner surface of at least one of the first side plate 400 and the second side plate 500 so that an axial end a of the heater 110 is disposed inside the first receiving groove AH1.

[0094] That is, the first support rib SR1 is configured to wrap the axial end a of the heater 110, and at the same time, an air layer is located inside the first accommodating groove AH1. When configured as described above, the movement of heat generated in the heat-generating component 100 is blocked by the air layer inside the first accommodating groove AH1, and is effectively prevented from being released to the outside through the first side plate 400 and the second side plate 500, thereby minimizing heat loss.

[0095] like Fig. 9 and Fig.10As shown, the axial end a of the first support rib SR1 can be closely attached to the first inner cover 120 and the second inner cover 130. When arranged in the manner described above, even if the air layer inside the first receiving groove AH1 is heated during the use of the massage ball 10, since the axial end a of the first support rib SR1 is closely attached to the first inner cover 120 and the second inner cover 130, the high-temperature air layer can be effectively prevented from moving by convection, and as a result, it can be prevented from being released to the outside through the first side plate 400 and the second side plate 500, thereby minimizing heat loss.

[0096] like Figures 8 to 11 As shown, a second receiving groove AH2 may be provided on the inner surface of at least one of the first side plate 400 and the second side plate 500 . The second receiving groove AH2 is formed to extend along the axial direction a and is arranged outside the first receiving groove AH1 in the radial direction r.

[0097] An air layer is formed inside the second accommodating groove AH2. When configured as described above, the movement of heat generated in the heat-generating component 100 is blocked by the air layer inside the second accommodating groove AH2 and is effectively prevented from being released to the outside through the first side plate 400 and the second side plate 500, thereby minimizing heat loss.

[0098] In addition, the second receiving groove AH2 can be arranged outside the first receiving groove AH1 in the radial direction r. That is, the air layer inside the first receiving groove AH1 is used to achieve primary heat insulation, and the air layer inside the second receiving groove AH2 is used to achieve secondary heat insulation, thereby effectively preventing the heat generated in the heater 110 from being released to the outside through the first side plate 400 and the second side plate 500, thereby minimizing heat loss.

[0099] In addition, the air layer inside the second accommodating groove AH2 may effectively prevent the heat transferred to the first and second inner covers 120 and 130 from being released to the outside through the first and second side plates 400 and 500 , thereby minimizing heat loss.

[0100] like Figures 8 to 11 As shown, a second supporting rib SR2 configured with a second receiving groove AH2 may be provided on an inner surface of at least one of the first side plate 400 and the second side plate 500 .

[0101] That is, an air layer is formed inside the second accommodating groove AH2 through the second supporting rib SR2. When arranged as described above, the movement of heat generated in the heat-generating component 100 is blocked by the air layer inside the second accommodating groove AH2 and is effectively prevented from being released to the outside through the first side plate 400 and the second side plate 500, thereby minimizing heat loss.

[0102] like Fig. 9and Fig.10 As shown, the axial end a of the second support rib SR2 can be closely attached to the first inner cover 120 and the second inner cover 130. When arranged in the manner described above, even if the air layer inside the second receiving groove AH2 is heated during the use of the massage ball 10, since the axial end a of the second support rib SR2 is closely attached to the first inner cover 120 and the second inner cover 130, the high-temperature air layer can be effectively prevented from moving by convection, and as a result, it can be prevented from being released to the outside through the first side plate 400 and the second side plate 500, thereby minimizing heat loss.

[0103] like Figure 4 As shown, an insertion groove IH into which the rotation pin P is inserted is provided on the outer surface of the heat generating component 100 , and the rotation pin P can support the inner surface of the outer cover component 300 in a state of being inserted into the insertion groove IH.

[0104] To this end, the first inner cover 120 and the second inner cover 130 are respectively provided with an insertion groove IH for inserting the rotation pin P, and an opening portion may be provided outside the insertion groove IH in the radial direction r so that a portion of the rotation pin P is exposed in the radial direction r.

[0105] That is, the rotation pin P may be exposed to the outside in the radial direction r from the insertion groove IH through the opening, and as described above, the portion exposed to the outside in the radial direction r contacts the outer cover member 300 and transfers heat in a conductive manner.

[0106] That is, since there are provided a rotating pin P rotatably inserted into the first inner cover 120 and the second inner cover 130 and an outer cover component 300 rotatably arranged on the outer surface of the rotating pin P, heat is transferred by conduction through the rotating pin P. Therefore, not only the warm massage effect can be improved, but the outer cover component 300 can be smoothly rotated by the rotating pin P. Therefore, no noise will be generated during use, and the problem of reduced durability due to wear will not occur.

[0107] As an example, the insertion groove IH may include a first slot extending from one side of the axial direction a to the other side. In this case, a disengagement prevention surface for preventing the rotation pin P from being disengaged may be provided on the other side of the axial direction a of the insertion groove IH. When provided in the manner described above, since the operator can simply assemble by inserting the rotation pin P from one side of the axial direction a to the other side, the assemblability is improved.

[0108] As another example, the insertion groove IH may include a second slot extending from the other side of the axial direction a to one side. In this case, a disengagement prevention surface for preventing the rotation pin P from being disengaged may be provided on the one side of the axial direction a of the insertion groove IH. When provided in the manner described above, since the operator can simply assemble by inserting the rotation pin P from the other side of the axial direction a to one side, the assemblability is improved.

[0109] As another example, the insertion groove IH includes a first slot extending from one side of the axial direction a to the other side and a second slot extending from the other side of the axial direction a to one side, and the first slot and the second slot may be alternately arranged in the circumferential direction. When arranged as described above, since one side of the axial direction a of the outer cover component 300 is supported by the rotation pin P inserted into the first slot, and the other side of the axial direction a of the outer cover component 300 is supported by the rotation pin P inserted into the second slot, the outer cover component 300 can be smoothly rotated.

[0110] As another example, the insertion groove IH includes a first slot extending from one side to the other side in the axial direction a and a second slot extending from the other side to one side in the axial direction a, and the first slot and the second slot may be arranged along the axial direction a. When arranged as described above, since one side in the axial direction a of the outer cover member 300 is supported by the rotation pin P inserted into the first slot and the other side in the axial direction a of the outer cover member 300 is supported by the rotation pin P inserted into the second slot, the outer cover member 300 can be smoothly rotated.

[0111] like Figure 4 As shown, in the first inner cover 120 and the second inner cover 130, any one inner cover disposed adjacent to the user may be provided with a support surface SF in surface contact with the inner surface of the outer cover part 300, and the other inner cover may be provided with an insertion groove IH.

[0112] That is, in the first inner cover 120 and the second inner cover 130, the support surface SF of any one of the inner covers arranged adjacent to the user can be a surface-contact sliding surface, so that the outer cover part 300 can rotate relatively. When arranged in the manner as described above, even when the massage ball 10 applies pressure to the user, the outer cover part 300 is subjected to the load of the user and the outer cover part 300 is in contact with the support surface SF, the outer cover part 300 can also rotate smoothly.

[0113] In addition, the other inner cover may be provided with an insertion groove 1H for inserting the rotation pin P. The rotation pin P may be provided to rotate relative to the other inner cover. That is, since the rotation pin P is provided to rotate relative to the other inner cover while being inserted into the other inner cover, the rotation of the outer cover member 300 can be performed more smoothly.

[0114] In addition, since heat can be transferred by conduction through the rotating pin P during the rotation of the outer cover member 300, the thermal massage effect can be improved.

[0115] At this time, a sliding surface may be further provided on the outer surface of the other inner cover, so that when the massage ball 10 applies pressure to the user, even if the outer cover component 300 is deformed and contacts the other inner cover, the outer cover component 300 may smoothly rotate through the sliding surface.

[0116] In addition, in the first inner cover 120 and the second inner cover 130, a support surface SF is provided in any one of the inner covers arranged adjacent to the user so that the outer cover part 300 can rotate relatively while supporting the user's load, and an insertion groove IH for inserting the rotating pin P is provided in the other inner cover. Therefore, even when the user's load is applied, the outer cover part 300 can rotate smoothly while preventing the user's load from being directly applied to the rotating pin P, thereby minimizing the wear of the rotating pin P.

[0117] On the other hand, the massage ball 10 can be provided in a warm massage device, which may include: a conveying part, which moves the massage ball 10 for applying pressure to the user along the length direction; a base part, which is provided with a support arm fixedly coupled to the massage ball 10; a lifting part, which raises or lowers the base part along the height direction; and a power supply part, which supplies current to the massage ball 10. The power supply part may be electrically connected to the power line 20.

[0118] This warm massage device can be inserted into a cushion that supports the user's body. When inserted into the cushion, the warm massage device can move along the length direction (the same direction as the user's spine arrangement direction) and apply pressure to the user's body.

[0119] This cushion can be arranged on the main body for supporting the upper body of the user, and the main body can be connected with an auxiliary part for supporting the lower body of the user. At this time, the main body can be arranged to support not only the upper body of the user but also the buttocks, and the auxiliary part can also be arranged to support only the legs of the user.

[0120] In this case, the cushion may be provided in the auxiliary part that supports the lower body of the user, and the cushion may be provided in both the main body part and the auxiliary part.

[0121] The main body provided with the cushion may be provided with a separate leg member so that the upper surface of the cushion is spaced apart from the ground, whereby the user can receive massage in a comfortable posture.

[0122] Such a leg member can be manufactured in a generally quadrilateral strip shape. That is, it can include: a side frame corresponding to the side of the main body; a lower frame supported on the ground; and a connecting frame connecting the side frame and the lower frame. The above frames can be manufactured as one piece, or manufactured separately and then combined. Among them, the side frame is manufactured in a plate shape, and the lower frame can be manufactured in a rod shape.

[0123] The main body may be provided with a guide groove, and the auxiliary part may be provided with a guide protrusion inserted into the guide groove, so that the auxiliary part can slide. Alternatively, the auxiliary part may be provided with a guide groove, and the main body may be provided with a guide protrusion, so that the auxiliary part can slide.

[0124] The massage balls 10 can be arranged on both sides in the width direction (on both sides of the user's spine as the center), so that pressure can be applied to acupuncture points on both sides along the user's spine (for example, acupuncture points according to the foot-sun bladder meridian) to provide a massage effect.

[0125] In this case, the conveying part may be provided with a plate-shaped conveying plate member for the base part and the lifting part to be provided, and base ribs may be provided at both ends of the conveying plate member in the width direction. The base ribs may be provided with support rollers, which are movably arranged along the guide rails, which are arranged along the length direction. In addition, the conveying part may be provided with a conveying driving member that provides a driving force to move the support rollers along the guide rails.

[0126] In addition, the base portion may be provided with a support arm as described above and configured to be rotatable at a predetermined angle. The lifting portion may be provided with a rack-shaped lifting component and a pinion-shaped lifting drive component, and a separate drive motor may be connected to the lifting drive component, so that the lifting component can be set to rise or fall according to rotating in one direction or the other.

[0127] As described above, according to an embodiment of the present invention, the massage ball 10 is provided with a clip component 200. In a state where the clip component 200 is provided, the clip component 200 is used to fix the first inner cover 120 arranged on one side of the radial direction r to wrap the heater 110 and the second inner cover 130 arranged on the other side of the radial direction r to wrap the heater 110. The outer cover component 300 is rotatably arranged on the outer surfaces of the first inner cover 120 and the second inner cover 130. In the process of heat generated in the heater 110 being transferred through the first inner cover 120 and the second inner cover 130, even if thermal expansion occurs in the first inner cover 120 and the second inner cover 130, the heat transfer performance can be prevented from being reduced, so that sufficient heat can be transferred to the user and the combined state of the first inner cover 120 and the second inner cover 130 can be stably maintained.

[0128] Although one embodiment of the present invention has been described, the concept of the present invention is not limited to the embodiment presented in this specification, and an ordinary technician who understands the concept of the present invention can easily propose other embodiments within the same scope of the concept by adding, changing, deleting, and appending constituent elements, which also falls within the scope of the concept of the present invention.
