Description

Massage ball with clip attachment

[0001] The present invention relates to a massage ball, and more particularly, to a massage ball provided with a clip member.

[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] These spinal thermal massage devices are equipped with heat-generating massage balls that apply thermal stimulation while applying pressure to the user. A PTC heater is located at the center of the massage ball, which heats when current is applied.

[0004] Korean Patent Publication No. 1711030 (registered on February 22, 2017) discloses a conventional PTC heater. This PTC heater is configured to transfer heat to the outside by including a heating tube with a PTC assembly mounted therein, and a plurality of heating tubes are configured to be joined using a joining protrusion and a joining groove while the PTC assembly is positioned therein.

[0005] However, when configured in this manner, the heat generated in the PTC assembly undergoes thermal expansion in the heating tube during the process of being transferred through the heating tube, and this thermal expansion causes a gap to form between the PTC assembly and the heating tube, resulting in a problem of reduced heat transfer performance.

[0006] In addition, there is a problem that the bonding strength of the bonding projection and bonding groove decreases due to thermal expansion occurring in the heating tube, causing the bonding state of multiple heating tubes to become unstable.

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

[0008] (Patent Document 1) Korean Patent Publication No. 1711030 (registered on February 22, 2017)

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] FIG. 1 is a perspective view illustrating an assembled state of a massage ball equipped with a clip member according to an embodiment of the present invention, FIG. 2 is a perspective view illustrating a separated state of an outer cover member of a massage ball equipped with a clip member according to an embodiment of the present invention, FIG. 3 is a perspective view illustrating a state in which a heating member and a clip member of a massage ball equipped with a clip member are coupled according to an embodiment of the present invention, and FIG. 4 is a front view illustrating a state in which a heating member and a clip member of a massage ball equipped with a clip member are coupled according to an embodiment of the present invention. Here, the a direction is an axial direction, and the b direction is a radial direction. In order to clearly describe the present invention, parts that are not related to the description are omitted from the drawings.

[0037] As illustrated in FIGS. 1 to 4, a massage ball equipped with a clip member according to one embodiment of the present invention is a massage ball (10) that provides a thermal massage effect while pressing a user, and the massage ball (10) includes a heating member (100) equipped with a heater (110), a first inner cover (120) arranged on one side in the radial direction (r) to surround the heater (110), and a second inner cover (130) arranged on the other side in the radial direction (r) to surround the heater (110).

[0038] At this time, the massage ball (10) can be coupled to a support arm placed on the thermal massage device, and the support arm can be arranged on the support portion of the massage device. The support arm can be configured to be rotatable at a certain angle during the thermal massage process. Either the first side plate (400) or the second side plate (500) described later can be coupled to the support arm, and the heater (110) is fixedly coupled to this side plate, so that the massage ball (10) can stably support the user's body during the user's pressing process, and a stable current supply to the heater (110) is enabled.

[0039] The massage ball (10) may be equipped with a power wire (20) that supplies current, and when current is supplied to the heater (110) through this, the heater (110) can generate heat. This heater (110) may be a PTC heater, but is not necessarily limited thereto, and may be any other configuration, such as a heating wire, as long as it has a configuration capable of generating heat.

[0040] At this time, the massage ball (10) includes a clip member (200) that secures the first inner cover (120) and the second inner cover (130), and an outer cover member (300) that is rotatably arranged on the outer surfaces of the first inner cover (120) and the second inner cover (130). This outer cover member (300) may be made of an elastic material so as to reduce pain caused by the pressing force when the massage ball (10) presses the user during a thermal massage. For example, the outer cover member (300) may be made of a silicone material.

[0041] An insert (310) may be provided on the inner surface of the outer cover member (300). The insert (310) may be made of aluminum with high heat transfer performance so that the heat transferred through the heating member (100) can smoothly move to the outer cover member (300). However, the insert is not limited thereto and any material with high heat transfer performance may be used. The insert (310) may be integrally provided by insert injection during the injection molding process of the outer cover member (300).

[0042] In addition, the insert (310) can be formed to extend from one end of the axial direction (a) of the outer cover member (300) to the other end so as to secure structural stability while supporting the inner surface of the outer cover member (300), thereby not only enabling easy assembly of the outer cover member (300) during the manufacturing process of the massage ball (10), but also enabling stable load support even when a user's load is applied to the massage ball (10) during the thermal massage process.

[0043] In addition, a sliding surface may be provided on the inner surface of the insert (310), and when the sliding surface is provided in this way, the outer cover member (300) can rotate smoothly.

[0044] That is, as described above, in a state where a clip member (200) is provided to fix a first inner cover (120) disposed on one side in the radial direction (r) to surround the heater (110) and a second inner cover (130) disposed on the other side in the radial direction (r) to surround the heater (110), and an outer cover member (300) is rotatably disposed on the outer surfaces of the first inner cover (120) and the second inner cover (130), so that even if thermal expansion occurs in the first inner cover (120) and the second inner cover (130) in the process of heat generated from the heater (110) being transferred through the first inner cover (120) and the second inner cover (130), sufficient heat can be transferred to the user by preventing a decrease in heat transfer performance, and the combined state of the first inner cover (120) and the second inner cover (130) can be stably maintained.

[0045] FIG. 5 is a perspective view illustrating a clip member of a massage ball equipped with a clip member according to one embodiment of the present invention, and FIG. 6 is a cross-sectional view illustrating a state in which a heating member and a clip member of a massage ball equipped with a clip member according to one embodiment of the present invention are combined.

[0046] As illustrated in FIGS. 5 and 6, the clip member (200) includes a body (210) and a pair of legs (220) extending from the body (210) in an axial direction (a), and one of the legs (220) of the pair of 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).

[0047] At this time, a pair of legs (220) may be configured to be elastically deformable outward in the radial direction (r) with respect to the body (210). With this configuration, a pair of legs (220) are elastically deformed in 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.

[0048] As illustrated in FIG. 4, the first inner cover (120) may be provided with a first insertion hole (121) into which one of the pair of legs (220) is inserted and supported, and the second inner cover (130) may be provided with a second insertion hole (131) into which the other of the pair of legs (220) is inserted and supported.

[0049] That is, the worker can simply assemble the clip member (200) by placing it on one side of the axial direction (a) of the heating member (100) and assembling it so that one leg (220) of a pair of legs (220) is inserted into the first insertion hole (121) and the other leg (220) of a pair of legs (220) is inserted into the second insertion hole (131).

[0050] In addition, the heat generated from the heater (110) is transferred through the first inner cover (120) and the second inner cover (130) in a conductive manner. 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 transferred through a conductive manner only moves to the remaining portion where the first insertion hole (121) and the second insertion hole (131) are not formed. This is because the heat flows in the direction where the resistance is less formed. With this configuration, the outer cover member (300) can be quickly heated through the first inner cover (120) and the second inner cover (130).

[0051] FIG. 7 is a cross-sectional view illustrating a modified example of a state in which a heating member and a clip member of a massage ball equipped with a clip member according to one embodiment of the present invention are combined.

[0052] As illustrated in Fig. 7, the inner surfaces of the first insertion hole (121) and the second insertion hole (131) may each be provided with a seating groove (SH) formed inwardly in the radial direction (r) so that the legs (220) are respectively seated.

[0053] As described above, the worker assembles the clip member (200) so that 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) while placing the clip member (200) on one side of the axial direction (a) of the heating member (100). If a settling groove (SH) formed inwardly in the radial direction (r) is provided on the inner surface of each of the first insertion hole (121) and the second insertion hole (131), the first inner cover (120) and the second inner cover (130) can be stably maintained in a coupled state when the elastic restoring force of the pair of legs (220) is applied to the settling groove (SH) while each of the pair of legs (220) is placed and placed in the settling groove (SH).

[0054] As illustrated in FIG. 6, the body (210) may be provided with a heat transfer surface (211) curved along the axial direction (a).

[0055] In this way, when the body (210) is provided with a heat transfer surface (211), heat generated through 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 heat can be smoothly transferred in a conductive manner.

[0056] To this end, the heat transfer surface (211) can be arranged in thermal contact with the heater (110), and if configured in this manner, the heat generated through 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, if the heat transfer surface (211) is curved along the axial direction (a), the heat transfer surface (211) can be easily arranged in thermal contact with the heater (110) during the process of assembling the clip member (200), thereby enabling stable heat transfer.

[0057] At this time, the heat transfer surface (211) may be arranged to be curved in the opposite direction to the axial direction (a), or may be arranged in a straight shape parallel to the radial direction (r). Even if configured in this way, if the heat transfer surface (211) is arranged in thermal contact with the heater (110), the heat generated through the heater (110) can be quickly transferred to the first inner cover (120) and the second inner cover (130) through the body (210).

[0058] As illustrated in Fig. 6, a pair of legs (220) may each be provided with a guide rib (221) extending outward in the radial direction (r).

[0059] As described above, the worker assembles the clip member (200) so that 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) while placing the clip member (200) on one side of the axial direction (a) of the heating member (100).

[0060] In this case, if a pair of legs (220) are each provided with a guide rib (221) that extends outward in the radial direction (r), the clip member (200) can be easily assembled as the pair of legs (220) are easily elastically deformed outward in the radial direction (r) through the guide rib (221) during the assembly process of the clip member (200).

[0061] FIG. 8 is a perspective view showing an exploded state of a massage ball equipped with a clip member according to one embodiment of the present invention, FIG. 9 is a cross-sectional view of part I-I of FIG. 1, FIG. 10 is a cross-sectional view of part II-II of FIG. 1, and FIG. 11 is a front view showing a first side plate and a second side plate of a massage ball equipped with a clip member according to one embodiment of the present invention.

[0062] As shown in FIGS. 8 to 11, a first side plate (400) and a second side plate (500) fixedly supported to the heating member (100) may be provided on one side (a) and the other side of the heating member (100), respectively.

[0063] A fastening member (30) may be provided so that the first side plate (400) and the second side plate (500) are respectively coupled to one side and the other side in the axial direction (a) of the first inner cover (120) and the second inner cover (130).

[0064] In this way, when the first side plate (400) and the second side plate (500) are provided, even if the external cover member (300) rotates relative to the heating member (100) while the heating member (100) is fixed so as not to rotate, the external cover member (300) can be prevented from being arbitrarily separated in the axial direction (a).

[0065] As shown in FIGS. 8 to 11, a first support rib (SR1) for strength reinforcement may be provided on the inner surface of at least one of the first side plate (400) and the second side plate (500).

[0066] As shown in FIGS. 8 to 11, a second support rib (SR2) for strength reinforcement may be provided on the inner surface of at least one of the first side plate (400) and the second side plate (500).

[0067] As shown in Fig. 4, the outer surface of the heating member (100) is provided with an insertion groove (IH) into which a rotation pin (P) is inserted, and the rotation pin (P) can support the inner surface of the outer cover member (300) while being inserted into the insertion groove (IH).

[0068] To this end, the first inner cover (120) and the second inner cover (130) are each provided with an insertion groove (IH) into which a rotation pin (P) is inserted, and an opening may be provided on the outer side of the insertion groove (IH) in the radial direction (r) so that a part of the rotation pin (P) is exposed in the radial direction (r).

[0069] That is, the rotary pin (P) can be exposed radially (r) outward from the insertion groove (IH) through the opening, and the portion exposed radially (r) outward in this way transfers heat in a conductive manner while coming into contact with the outer cover member (300).

[0070] That is, since a rotary pin (P) is provided that is rotatably inserted into the first inner cover (120) and the second inner cover (130) and an external cover member (300) that is rotatably placed on the outer surface of the rotary pin (P), heat is transferred through the rotary pin (P) in a conductive manner, thereby improving the thermal massage effect. In addition, since the external cover member (300) can rotate smoothly through the rotary pin (P), no noise is generated during use and no problem of durability degradation due to wear occurs.

[0071] For example, the insertion groove (IH) may include a first slot extending from one side in the axial direction (a) to the other side. At this time, a separation prevention surface may be provided on the other side in the axial direction (a) of the insertion groove (IH) to prevent the rotation pin (P) from coming off. With this configuration, the worker can simply assemble the rotation pin (P) by inserting it from one side in the axial direction (a) to the other side, thereby improving the assembly efficiency.

[0072] As another example, the insertion groove (IH) may include a second slot extending from the other side in the axial direction (a) to one side. At this time, a separation prevention surface may be provided on the one side in the axial direction (a) of the insertion groove (IH) to prevent the rotation pin (P) from coming off. With this configuration, the worker can simply assemble the rotation pin (P) by inserting it from the other side in the axial direction (a) to one side, thereby improving the assembly efficiency.

[0073] As another example, the insertion groove (IH) includes a first slot extending from one side in the axial direction (a) to the other side and a second slot extending from the other side in the axial direction (a) to one side, wherein the first slot and the second slot may be arranged alternately along the circumferential direction. With this configuration, 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, thereby enabling smooth rotation of the outer cover member (300).

[0074] As another example, the insertion groove (IH) includes a first slot extending from one side in the axial direction (a) to the other side and a second slot extending from the other side in the axial direction (a) to one side, wherein the first slot and the second slot can be arranged along the axial direction (a). With this configuration, 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, thereby enabling smooth rotation of the outer cover member (300).

[0075] As illustrated in FIG. 4, one of the first inner cover (120) and the second inner cover (130) disposed adjacent to the user may be provided with a support surface (SF) that makes surface contact with the inner surface of the outer cover member (300), and the other inner cover may be provided with an insertion groove (IH).

[0076] That is, the support surface (SF) provided on one of the inner covers (120) and the second inner cover (130) that is positioned adjacent to the user may be a sliding surface that makes surface contact with the outer cover member (300) so that the outer cover member (300) can rotate relative to the user. With this configuration, even if the user's load is applied to the outer cover member (300) during the process of the massage ball (10) pressing the user, the outer cover member (300) can smoothly rotate even when the outer cover member (300) comes into contact with the support surface (SF).

[0077] Additionally, another inner cover may be provided with an insertion groove (IH) into which a rotation pin (P) is inserted. The rotation pin (P) may be configured to rotate relative to the other inner cover. That is, since the rotation pin (P) is configured to rotate relative to the other inner cover while being inserted, the rotation of the outer cover member (300) can be performed more smoothly.

[0078] In addition, since heat can be transferred in a conductive manner through the rotating pin (P) during the process of rotating the outer cover member (300), the thermal massage effect is also improved.

[0079] At this time, the outer surface of the other inner cover may be provided with a sliding surface, so that even if the outer cover member (300) is deformed and comes into contact with the other inner cover during the process of the massage ball (10) pressing the user, smooth rotation of the outer cover member (300) is possible through the sliding surface.

[0080] In addition, among the first inner cover (120) and the second inner cover (130), one inner cover disposed adjacent to the user is provided with a support surface (SF) so that the outer cover member (300) can rotate relative to the user while supporting the user's load, and the other inner cover is provided with an insertion groove (IH) into which a rotation pin (P) is inserted, so that the outer cover member (300) can rotate smoothly even when the user's load is applied, and at the same time, the user's load is prevented from being directly applied to the rotation pin (P), thereby minimizing wear on the rotation pin (P).

[0081] Meanwhile, the above-described massage ball (10) may be installed in a thermal massage device, and the thermal massage device may include a transport unit that moves the massage ball (10) that pressurizes the user in the longitudinal direction, a support unit equipped with a support arm to which the massage ball (10) is fixedly connected, a raising / lowering unit that raises or lowers the support unit in the height direction, and a power supply unit that supplies current to the massage ball (10). The power supply unit may be electrically connected to the power wire (20) described above.

[0082] These thermal massage devices can be inserted and placed into a pad that supports the user's body, and the thermal massage devices are inserted and placed into the pad and move along the length direction (in the same direction as the user's spinal alignment) to apply pressure to the user's body.

[0083] Such pads may be provided on a main body supporting the user's upper body, and an auxiliary part supporting the user's lower body may be connected to the main body. In this case, the main body may be configured to support not only the user's upper body but also the buttocks, and the auxiliary part may be configured to support only the user's legs.

[0084] At this time, pads can also be provided on the auxiliary part that supports the user's lower body, and it is also possible to configure the pads to be provided on both the main body and the auxiliary part.

[0085] The main body equipped with a pad may be provided with a separate leg member so that the upper surface of the pad is positioned away from the ground, thereby allowing the user to receive a massage in a comfortable position.

[0086] These leg members can be manufactured in a roughly rectangular band shape. That is, they can include side frames corresponding to the sides of the main body, a lower frame supported on the ground, and a connecting frame connecting the side frames and the lower frame. The above-mentioned frames can be manufactured as a single unit, or can be manufactured separately and then joined. Here, the side frames can be manufactured in a plate shape, and the lower frame can be manufactured in a rod shape.

[0087] The aforementioned main body portion may be configured to have a guide groove formed therein, and the auxiliary portion may be configured to have a guide protrusion formed therein to be inserted into the guide groove, so that the auxiliary portion can slide. Alternatively, it is also possible to configure the auxiliary portion to have a guide groove formed therein, and the main body portion to have a guide protrusion formed therein, so that the auxiliary portion can slide therein.

[0088] Massage balls (10) can be placed on both sides in the width direction (both sides centered on the user's spine), thereby providing a massage effect by applying pressure to acupressure points (for example, acupressure points according to the foot-taiyang bladder meridian) located on both sides along the user's spine.
