Description

[Technical Field]

[0001] The present invention relates to a lower leg massage device. [Background technology]

[0002] Patent Document 1 discloses a pneumatic massage device equipped with a massage bag that massages the user's lower legs. The massage bag has a zipper, and the user wraps the massage bag around the lower legs with the zipper open, and then closes the zipper to wear the massage bag. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-30948 Summary of the Invention [Problem to be solved by the invention]

[0004] In such a massage device for massaging the lower legs, the user must wrap the massage bag around the lower legs every time, which is time-consuming and can be inconvenient for the user.

[0005] The present invention has been made in view of the above points, and an object of the present invention is to provide a lower leg massage device that can be easily worn by a user's lower legs. [Means for solving the problem]

[0006] The first aspect is This lower leg massage device comprises a casing, a lower leg insertion section having a pair of vertical cylindrical sections extending in the vertical direction and into which the user's lower legs are inserted, an airbag provided in the lower leg insertion section for pressing against the lower legs, an air supply and exhaust mechanism for supplying air to the airbag and discharging air from the airbag, and a support member located within the casing for keeping the vertical cylindrical sections in an upright position.

[0007] In the first mode, the vertical tube portion is held in an upright position by the support member, so the user only needs to insert their lower limbs into the vertical tube portion from above. This eliminates the need for the complicated action of wrapping the vertical tube portion around the lower limbs, and allows the user to easily insert their lower limbs into the lower limb insertion portion.

[0008] The second aspect is the first aspect, The casing has an installation section on which the vertical tube section is installed, the installation section having a first surface facing the circumferential surface of the vertical tube section in the front-to-rear direction, the support member having elasticity, a first end portion which is one end of the support member being fixed to the vertical tube section, and a second end portion which is the other end of the support member being fixed forward of the vertical tube section.

[0009] In the second aspect, the support member is elastic, so that the vertical tube portion is biased so as to be pulled forward. This prevents the vertical tube portion from falling backward or to the side. In particular, by pulling the vertical tube portion forward, a portion of the outer circumferential surface of the vertical tube portion can abut against the first surface of the installation portion. This allows the vertical tube portion to maintain an upright state.

[0010] The third aspect is the second aspect, The lower limb insertion section has a horizontal tube section extending forward from a lower portion of the vertical tube section, and the second end section is fixed forward of the horizontal tube section.

[0011] In the third aspect, the support member is relatively long because it is provided from the front of the horizontal tube portion to the surface of the vertical tube portion facing the first surface on the circumferential surface of the vertical tube portion. Here, the support member is elastic. For example, if the support member is a band-shaped member, a longer band stretches more than a shorter band. Therefore, for example, by grasping the vertical tube portion with one's hand and pulling it backward, the vertical tube portion can be tilted backward from the rear surface of the casing, and when the hand is released, the vertical tube portion can naturally return to the installation portion. In this way, the vertical tube portion has greater freedom of movement than if it were fixed to the installation portion, and the ease of wearing the lower limb can also be improved.

[0012] A fourth aspect is the second or third aspect, The second end is fixed at a height position lower than that of the first end.

[0013] In the fourth aspect, the support member is inclined downward from the first end to the second end. That is, the support member can be made longer than when the first end and the second end are at the same height. This improves the effect of the third aspect.

[0014] A fifth aspect is any one of the first to third aspects, The device further includes a fastener provided on each of the pair of vertical cylindrical portions for opening and closing the circumferential surface of the vertical cylindrical portion in the up-down direction, and a handle member connected to each of the pull members of the fastener.

[0015] In the fifth aspect, the handle member can be held and the pull members of the two fasteners can be raised and lowered simultaneously, eliminating the need to raise and lower the pull members one by one, making it easier to attach the lower leg to the tubular member. [Effects of the Invention]

[0016] As described above, according to the present disclosure, the user's lower legs can be easily attached to the lower leg massage device. [Brief explanation of the drawings]

[0018] Hereinafter, each embodiment of the present invention will be described in detail with reference to the drawings. The following description of each embodiment is essentially merely an example and is not intended to limit the present invention, its applications, or its uses. In the following description, "front," "rear," "right," "left," "upper," and "lower" refer to the respective directions when the lower leg massage device is viewed from the front, and specifically refer to the directions illustrated in each drawing.

[0019] (1) Overall configuration of the lower limb massage device The lower leg massage device (1) shown in Figs. 1 to 4 is a device for massaging the lower legs of a user. The lower legs refer to the part of the user's legs from below the knees to the toes. The lower leg massage device (1) of the present disclosure mainly includes a casing (10), a cover part (20), a lower leg insertion part (30), an airbag (40), and an air supply / exhaust mechanism (50). Each component will be described below in order.

[0020] (1-1) Casing The casing 10 shown in Figures 1 and 2 is generally box-shaped. The casing 10 has a front panel 11, a right side panel 12, a left side panel 13, a rear portion 14, a top panel 15, and a bottom panel 16. The front panel 11, the right side panel 12, and the left side panel 13 form the front, right side, and left side of the casing 10, respectively.

[0021] The rear surface portion (14) constitutes the rear surface of the casing (10). The rear surface portion (14) is provided with a mounting portion (70) in which a vertical tube portion (30a) of the lower leg insertion portion (30), which will be described later, is mounted. The mounting portion (70) is a pair of grooves (70) arranged side by side in the left-right direction. Each groove (70) is formed in a semi-cylindrical shape extending in the vertical direction from the bottom plate portion (16) to the top plate (15). In this way, the mounting portion (70) extends in the vertical direction and is formed so as to be recessed toward the inside (front) of the casing (10).

[0022] As shown in FIG. 3, an opening (73) is formed in the lower part of the installation portion (70). The opening (73) is a hole into which the horizontal cylindrical portion (30b), which will be described later, is inserted. In this embodiment, the rear surface of the casing (10) includes an inner surface, which is the inner surface of each groove (70). The inner surface of the groove (70) includes a first surface (71). The first surface (71) is a region of the inner surface of the groove (70) that faces the circumferential surface of the vertical cylindrical portion (30a) in the front-rear direction.

[0023] The top plate (15) shown in Figure 2 constitutes the upper surface of the casing (10). Two semicircular cutouts (15a) are formed in the rear portion of the top plate (15) and aligned in the left-right direction. The cutouts (15a) coincide with the positions of the grooves (70). In this way, the grooves (70) are formed so as to penetrate the top plate (15).

[0024] An operation unit 90 is provided on the top panel 15. The operation unit 90 is used by a user to input information such as power on / off of the lower leg massage device 1, selection of various massage courses, and operation modes of air pressure treatment in the airbag 40 (described later).

[0025] The bottom plate portion (16) forms the bottom surface of the casing (10). Predetermined devices constituting the sole massage section (60) are arranged on the bottom plate portion (16). Leg portions (17) are provided on the lower surface of the bottom plate portion (16). The legs (17) are arranged at the four corners of the lower surface of the bottom plate portion (16). The legs (17) are members that come into contact with the floor surface and support the lower leg massage device (1).

[0026] (1-2) Lid part The lid (20) shown in FIG. 1 is a rectangular member that covers the top plate (15). The lid (20) is detachable from the casing (10). When the lid (20) is attached to the casing (10), the lid (20) covers the cutout (15a) of the top plate (15). The lid (20) may have a cushioning material that has cushioning properties. This reduces the load on the buttocks when a user sits on the lid (20) with the lid (20) attached to the top plate (15).

[0027] (1-3) Lower limb insertion section The lower leg insertion section 30 shown in Figures 2 and 3 is a member into which the user's lower legs are inserted. The lower leg insertion section 30 is a pair of tubular members. The lower leg insertion section 30 is made of a relatively soft material such as resin or cloth. The lower leg insertion section 30 is configured in an L-shape when viewed from the side. The lower leg insertion section 30 has a vertical tubular section 30a and a horizontal tubular section 30b.

[0028] The vertical tube portion (30a) is a tube member that is worn on the lower leg, mainly from below the knee to the heel. The vertical tube portion (30a) is formed in a generally cylindrical shape. The vertical tube portion (30a) extends upward from the bottom of the casing (10). The lower end of the vertical tube portion (30a) is fixed to the bottom plate portion (16) of the casing (10). The height position of the upper end of the vertical tube portion (30a) is the same as or slightly lower than the height position of the top plate (15). The vertical tube portion (30a) is positioned so that a portion of the circumferential surface of the vertical tube portion (30a) faces the inner surface of the recessed groove (70), which is the installation portion (70).

[0029] A portion of the circumferential surface of the vertical tube portion (30a) is exposed to the outside when the lower leg massage device (1) is viewed from the rear. In other words, the rear surface of the vertical tube portion (30a) is exposed to the outside. Fasteners (31) extending in the vertical direction are provided on the rear surfaces of the vertical tube portions (30a). The fasteners (31) are provided on the rear surfaces of the vertical tube portions (30a) from the upper end to the lower end. The fasteners (31) open and close the circumferential surface of the vertical tube portion (30a) in the vertical direction. Specifically, by moving a pull member (32) provided on the fastener (31) downward, the vertical tube portion (30a) is opened, and by moving the pull member (32) upward, the vertical tube portion (30a) is closed.

[0030] The fastener 31 is provided with a rod-shaped handle member 35. One longitudinal end of the handle member 35 is connected to the pull member 32 of one of the vertical cylindrical portions 30a, and the other end is connected to the pull member 32 of the other vertical cylindrical portion 30a. The handle member 35 is detachable from each of the pull members 32.

[0031] The horizontal tube portion (30b) is a component that is worn mainly on the lower leg from the ankle to the base of the toes. The horizontal tube portion (30b) is connected to the lower end of the vertical tube portion (30a) and is formed to extend forward. The horizontal tube portion (30b) only needs to be connected to the vertical tube portion (30a), and the vertical tube portion (30a) and the horizontal tube portion (30b) do not need to be formed integrally.

[0032] The lower leg insertion section 30 has side walls 36 that cover the area around the ankles. The side walls 36 form the lower part of the vertical tube section 30a. Specifically, the side walls 36 form the right and left sides of the lower part of the vertical tube section 30a.

[0033] (2) Airbags The airbag (40) shown in Fig. 4 is disposed inside the lower leg insertion section (30). The airbag (40) is provided in each of the vertical cylinder section (30a) and the horizontal cylinder section (30b). The vertical cylinder section (30a) and the horizontal cylinder section (30b) enclose the airbag (40) so that the airbag (40) is not exposed to the outside.

[0034] The airbag (40) compresses the user's lower legs by air pressure. The airbag (40) is a bag-shaped component made of a relatively soft resin material. The airbag (40) expands when air flows into the bag and contracts when air flows out of the bag.

[0035] The airbag (40) includes a first airbag (40a), a second airbag (40b), and a third airbag (40c).

[0036] The first airbag (40a) presses against the instep and the sides of the instep. One first airbag (40a) is provided for each horizontal cylindrical portion (30b). The first airbag (40a) is provided on the top and side surfaces of the horizontal cylindrical portions (30b). The first airbag (40a) is provided with a first connection portion (41) to which an air hose (53) described below is connected.

[0037] The second airbags (40b) mainly press against the calves and shins. One second airbag (40b) is provided for each vertical cylinder portion (30a). The second airbags (40b) are provided around substantially the entire circumference of the vertical cylinder portion (30a). The second airbags (40b) are provided with second connection portions (42) to which an air hose (53) (described later) is connected.

[0038] The third airbags (40c) compress the area from the base of the instep to near the ankles. One third airbag (40c) is provided on each of the left and right side walls (36) of each vertical cylinder portion (30a). The third airbags (40c) are provided with third connection portions (43) to which an air hose (53) described below is connected.

[0039] (3) Intake and exhaust mechanism The air supply / exhaust mechanism (50) supplies air to each air bag (40) and exhausts air from each air bag (40). The air supply / exhaust mechanism (50) includes a pump (51), a solenoid valve (52), and an air hose (53).

[0040] The pump (51) supplies air to each air bag (40) through an air hose (53) or discharges air from each air bag (40) through the air hose (53).

[0041] The air hose (53) is an air passage that conveys air to the air bag (40) or to the outside by operation of the pump (51). The air hose (53) is composed of a plurality of air hoses. Specifically, the air hose (53) includes a first air hose (53a), a second air hose (53b), a third air hose (53c), and a fourth air hose (53d).

[0042] One end of the first air hose (53a) is connected to the pump (51), and the other end of the first air hose (53a) is connected to the solenoid valve (52).

[0043] One end of the second air hose (53b) is connected to the solenoid valve (52). The other end of the second air hose (53b) is connected to the third airbag (40c). Specifically, the second air hose (53b) extending from the solenoid valve (52) branches into four branches, which are connected to the third connecting portions (43) of the two third airbags (40c) of one lower leg insertion section (30) and the third connecting portions (43) of the two third airbags (40c) of the other lower leg insertion section (30).

[0044] One end of the third air hose (53c) is connected to the solenoid valve (52). The other end of the third air hose (53c) is connected to the second airbag (40b). Specifically, the third air hose (53c) extending from the solenoid valve (52) branches into two branches, which are connected to the second connection portion (42) of the second airbag (40b) of one lower leg insertion section (30) and the second connection portion (42) of the second airbag (40b) of the other lower leg insertion section (30), respectively.

[0045] One end of the fourth air hose (53d) is connected to the solenoid valve (52). The other end of the fourth air hose (53d) is connected to the first airbag (40a). Specifically, the fourth air hose (53d) extending from the solenoid valve (52) branches into two, which are connected to the first connection portion (41) of the first airbag (40a) of one lower leg insertion section (30) and the first connection portion (41) of the first airbag (40a) of the other lower leg insertion section (30), respectively.

[0046] The solenoid valves (52) switch the air flow in the air hoses (53) and adjust the flow rate of air flowing through each air hose (53).

[0047] (4) Sole Treatment Department As shown in Fig. 5, the lower leg massage device 1 has a sole massage section 60. The sole massage section 60 massages the soles of the user's feet. A horizontal cylinder section 30b is placed on the sole massage section 60. The sole massage section 60 mainly has a roller member 61, a first massage member 62, and a second massage member 63.

[0048] The roller member 61 is a cylindrical member that rotates to massage the arch of the foot. The roller member 61 is rotatably supported on a shaft 65 that extends in the left-right direction. The shaft 65 is connected to a motor (not shown) and rotates when driven by the motor.

[0049] The roller member (61) is configured to be large enough to touch the arch of the foot when the user's lower limbs are attached to the horizontal tube portion (30b). The roller member (61) has a plurality of ridges (61a). The ridges (61a) are formed to stand on the outer circumferential surface of the roller member (61). The ridges (61a) extend at a predetermined angle with respect to the direction of rotation of the roller member (61). As the roller member (61) rotates, the ridges (61a) press against the sole of the foot.

[0050] The first massage member (62) is disposed in front of the roller member (61). The first massage member (62) is a plate-shaped member. The plate surface of the first massage member (62) is inclined upward from the rear to the front.

[0051] The first massage member 62 has first protrusions 62a. The first protrusions 62a are a plurality of protrusions arranged on the plate surface of the first massage member. The first protrusions 62a press the sole of the foot at the portion corresponding to the palm. Specifically, when the sole of the foot is pressed against the first massage member 62, the first protrusions 62a press the palm of the foot.

[0052] The second massage member (63) is disposed behind the roller member (61). The second massage member (63) is a plate-shaped member. The plate surface of the second massage member (63) is generally horizontal.

[0053] The second massage member (63) has second protrusions (63a). The second protrusions (63a) are a plurality of protrusions arranged on the plate surface of the second massage member (63). The second protrusions (63a) press against the heel. Specifically, the second massage member (63) is connected to a predetermined link mechanism (not shown). The link mechanism moves the second massage member (63) back and forth in response to the rotation of the roller member (61). This causes the second protrusions (63a) to also move back and forth in the front and back direction, thereby providing a massage effect to the heel in contact with the second protrusions (63a).

[0054] (5) Vibration generating unit The sole massage unit 60 has a vibration generator 64. The sole massage unit 60 applies vibrations to the first massage members 62. The vibrations generated by the vibration generator 64 are transmitted to the first massage members 62. This allows the soles of the user's feet placed on the sole massage unit 60 to be massaged by the vibrations.

[0055] (6) Control device The lower leg massage device 1 includes a control device (not shown). The control device is connected to various devices of the lower leg massage device 1 by wire or wirelessly. The control device operates various devices such as the pump 51, the solenoid valve 52, the roller member 61, and the vibration generator 64 based on predetermined commands input to the operation unit 90 by a user.

[0056] (7) Operating a lower limb massage device An example of the operation of the lower leg massage device (1) will be described below.

[0057] The user turns on the power of the operation unit (90) and then selects a desired operation mode. The control device operates various devices of the lower leg massage device (1) based on the operation mode selected by the user's operation. The operation modes include a first mode, a second mode, and a third mode.

[0058] (7-1) First mode The first mode is an operation mode in which a massage is performed using the airbags (40). When the first mode is selected, the control device operates the pump (51). In the first mode, the pump (51) continuously repeats an air supply operation and an air discharge operation. In the air supply operation, air is transported from the pump (51) to the airbags (40) via the air hose (53). As a result, each airbag (40) gradually inflates and presses against the calves, shins, ankles, insteps, etc. In addition, when air is discharged from the airbags (40) via the air hose (53) in the air discharge operation, each airbag (40) contracts and the pressure is alleviated. In this way, the airbags repeatedly inflate and contract, thereby massaging the user's lower legs inserted in the lower leg insertion sections (30). In the first mode, the solenoid valve (52) may be controlled to select the airbags (40) to be supplied with air and exhausted.

[0059] (7-2) Second mode The second mode is an operating mode in which the sole massage section (60) provides a massage. When the second mode is selected, the control device controls the operation of the motor. The operation of the motor rotates the roller member (61). Controlling the operation of the motor controls the rotation speed of the roller member (61). This adjusts the intensity of the second mode. For example, when "strong" is selected in the second mode, the roller member (61) rotates at a relatively high rotation speed. When "weak" is selected in the second mode, it rotates at a relatively low rotation speed.

[0060] (7-3) Third mode The third mode is an operating mode in which the soles of the user's feet are massaged by vibration. When the third mode is selected, the control device controls the operation of the vibration generator (64). By controlling the vibration generator (64), the strength of the vibration is adjusted. For example, when "strong" is selected in the third mode, the sole massage section (60) vibrates relatively strongly. When "weak" is selected in the third mode, the sole massage section (60) vibrates relatively weakly.

[0061] (8) Support member 3 and 5, the lower leg massage device 1 has a support member 80 for holding the pair of vertical cylinder portions 30a in an upright position. The support member 80 is disposed inside the casing 10.

[0062] The support member (80) is stretchable. Specifically, the support member (80) includes a stretchable belt portion (81) and a string member (82) connected to one end of the belt portion (81). One support member (80) supports one vertical tube portion (30a).

[0063] Specifically, a first end portion (80a), which is one end of the support member (80), is fixed to the vertical tube portion (30a). The first end portion (80a) is the end of the support member (80) to which the string member (82) is not connected. The first end portion (80a) is provided on the surface of the circumferential surface of the vertical tube portion (30a) facing forward. The first end portion (80a) is provided at the lower end of the first surface (71), i.e., at the height of the connection portion between the vertical tube portion (30a) and the horizontal tube portion when the lower limb insertion portion (30) is viewed from the side.

[0064] In this embodiment, the second end (80b), which is the other end of the support member (80), is a string member attached to the end of the belt portion (81). The second end (80b) is fixed forward of the horizontal tube portion (30b). Specifically, the second end (80b) is fixed to a fixing portion (18) that is attached to the bottom plate portion (16) and disposed forward of the horizontal tube portion (30b). The fixing portion (18) is a rectangular plate-like member that extends upright from the bottom plate portion (16). An engagement structure that can engage with the string member (82) is provided at the upper end of the fixing portion (18). The engagement structure is formed in a hook shape at the upper end of the fixing portion (18). The second end (80b) is fixed by hooking the annular portion of the string member (82) onto the engagement structure.

[0065] The height position of the upper end of the fixing portion (18) is lower than the height position of the first end (80a). In other words, the second end (80b) is fixed at a height position lower than the first end (80a). As a result, the support member (80) is disposed above the horizontal tube portion (30b) and is provided so as to slope downward from the second end (80b) to the first end (80a).

[0066] (9) Example of installation on a lower limb massage device An example of a procedure for a user to attach and detach his / her lower legs to and from the lower leg massage device (1) will be described below.

[0067] With the lid portion (20) in the open state, the user grasps the handle member (35) and pulls it down, causing both pull members (32) to move down, and both vertical cylinder portions (30a) simultaneously enter the open state.

[0068] Next, the user inserts his / her lower limbs into the lower limb insertion section (30). Here, the vertical tube section (30a) is fixed to the casing (10) only at its lower end, and the outer circumferential surface of the vertical tube section (30a) is not fixed to the inner circumferential surface of the recessed groove (70). However, the vertical tube section (30a) is held in an upright position by the elastic support member (80). Therefore, as shown in FIG. 6, the vertical tube section (30a) can be tilted backward with the lower end of the vertical tube section (30a) as a fulcrum. This eliminates the need for the user to insert his / her lower limbs from directly above the vertical tube section (30a). For example, the user can insert his / her lower limbs into the vertical tube section (30a) relatively easily even while sitting.

[0069] The user pulls up the handle member (35), which raises both pull members (32) and simultaneously closes both vertical cylinder portions (30a).

[0070] When the operation of the lower leg massage device (1) is finished, the user pulls down the handle member (35) to open both vertical cylinder portions (30a). In this state, the user removes the lower leg from the lower leg insertion portion (30) and pulls up the handle member (35) again to close both vertical cylinder portions (30a).

[0071] Since the vertical cylinder portion (30a) is biased forward by the support member (80), the vertical cylinder portion (30a) naturally moves forward with the lower end of the vertical cylinder portion (30a) as a fulcrum and is accommodated inside the recessed groove (70).

[0072] (10) Features (10-1) Feature 1 The lower leg massage device (1) of this embodiment includes a support member (80) that is disposed in the casing (10) and maintains the upright state of the vertical cylinder portion (30a). As a result, the vertical cylinder portion (30a) is maintained in an upright position by the support member (80), and the user simply inserts their lower leg into the vertical cylinder portion (30a) from above. This eliminates the need for the complicated operation of wrapping the vertical cylinder portion around the lower leg, and allows the user to relatively easily attach the lower leg to the lower leg massage device.

[0073] (10-2) Feature 2 The lower leg massage device (1) of this embodiment has a groove (70) in which the vertical cylinder portion (30a) is placed. The groove (70) has a first surface facing the circumferential surface of the vertical cylinder portion (30a) in the front-rear direction. The support member (80) is flexible, and a first end portion (80a) which is one end of the support member (80) is fixed to the vertical cylinder portion (30a), and a second end portion (80b) which is the other end of the support member (80) is fixed forward of the vertical cylinder portion (30a).

[0074] In this manner, the vertical cylinder portion (30a) is pulled forward by the elastic support member (80), thereby preventing the vertical cylinder portion (30a) from tipping backward or to the side. In this embodiment, when the vertical cylinder portion (30a) is pulled forward, a portion of the outer circumferential surface of the vertical cylinder portion (30a) comes into contact with the first surface of the recessed groove (70). This allows the vertical cylinder portion (30a) to be held upright within the recessed groove (70).

[0075] Because the support member is flexible, the vertical tube portion can be pulled backward to move it. This allows the user to pull the vertical tube portion backward and place their lower limbs on the tube member in a rearward tilted state. The user can insert their lower limbs into the vertical tube portion even while sitting, making it relatively easy to place their lower limbs on the tube member.

[0076] (10-3) Feature 3 The lower limb insertion section (30) of this embodiment has a horizontal tube section (30b) extending forward from the lower portion of the vertical tube section (30a), and the second end section (80b) is fixed forward of the horizontal tube section (30b). As a result, the support member (80) extends from the front of the horizontal tube section (30b) to the vertical tube section (30a), allowing the support member (80) to be relatively long. Because the support member (80) is a stretchable band-shaped member, the longer the support member (80) is, the longer it can be stretched. As a result, the vertical tube section (30a) can be tilted further backward by pulling it rearward. This improves ease of fitting the lower limb into the lower limb insertion section (30).

[0077] (10-4) Feature 4 In the lower leg massage device (1) of this embodiment, the second end (80b) is fixed at a height position lower than the first end (80a). This allows the support member (80) to be longer than when the first end (80a) and the second end (80b) are provided at the same height. Since the support member (80) is longer in this manner, the vertical tube portion (30a) can be pulled and tilted further rearward, thereby improving ease of attachment of the lower leg to the lower leg insertion portion (30).

[0078] (10-5) Feature 5 The lower leg massage device (1) of this embodiment further includes fasteners (31) that open and close the circumferential surfaces of the pair of vertical tube portions (30a) in the vertical direction, and handle members (35) that are connected to the pull members (32) of the fasteners (31), respectively.

[0079] This allows the user to simultaneously raise and lower the pull members (32) of the two fasteners (31) by holding the handle member (35). This eliminates the need to raise and lower the pull members (32) one by one, allowing the user to easily insert and remove the lower limb into and from the lower limb insertion section (30).

[0080] (11) Other embodiments The lower leg massage device (1) of the above embodiment may be configured as follows.

[0081] The lower limb insertion section 30 may be configured with a vertical tube portion 30a and a horizontal tube portion 30b as separate bodies. When the lower limb insertion section 30 is configured with the vertical tube portion 30a and the horizontal tube portion 30b as separate bodies, the vertical tube portion 30a and the horizontal tube portion 30b do not need to be connected to each other, or a portion of the horizontal tube portion 30b may be connected to the vertical tube portion 30a.

[0082] Although it has been described that one end of the support member (80) is fixed to the surface of the vertical cylinder portion (30a) facing the first surface (71) and the other end is fixed to the front of the horizontal cylinder portion (30b), this is not limiting. For example, the first end (80a) may be provided in a region of the circumferential surface of the vertical cylinder portion (30a) facing laterally (i.e., on the side surface of the vertical cylinder portion (30a)). The second end (80b) may be provided on a side of the horizontal cylinder portion (30b). As long as the second end (80b) is fixed within the casing (10), the bottom plate portion (16) does not need to have a fixing portion (18).

[0083] Although the second end 80b of the support member 80 has been described as being lower in height than the first end 80a, this is not limiting and the second end 80b may be the same height as or higher than the first end 80a.

[0084] The support member 80 does not have to be a strip-shaped member as long as it is stretchable. For example, the support member 80 may be an annular member made of rubber. The support member 80 does not have to be stretchable.

[0085] In this embodiment, the second end portion (80b) of the support member (80) is described as being formed by the string member (82), but this is not limiting. The support member (80) may not have the string member (82). In this case, the support member (80) is formed by only the belt portion (81).

[0086] In this embodiment, it has been described that the inner surface of the groove (70), which is the installation portion (70), constitutes the rear surface portion (14) of the casing (10), but the installation portion (70) may also be provided inside the casing (10).

[0087] In the present embodiment, the installation portion (70) is described as being formed in a groove shape, but the shape is not limited thereto. The installation portion (70) may be configured so that the vertical cylinder portion (30a) can be placed therein.

[0088] The lower leg massage device (1) may have a member on the top plate (15) to allow a battery terminal such as a smartphone or tablet to be placed on it. This allows the user to enjoy watching videos or listening to music while receiving a massage. The lower leg massage device (1) may also have a port to which a charging cable for a smartphone or tablet can be connected. This allows the user to charge the smartphone or tablet while receiving a massage.

[0089] The lower leg massage device 1 may have a foldable stand provided near the front of the underside of the bottom plate 16 of the casing 10. The stand lifts the front of the underside of the bottom plate 16, tilting the casing 10 toward the user, making it easier for the user to insert their lower leg into the lower leg insertion section 30.

[0090] Although the embodiments and modifications have been described above, it will be understood that various modifications in form and detail are possible without departing from the spirit and scope of the claims. Furthermore, the above embodiments and modifications may be combined or substituted as appropriate as long as the functionality of the subject matter of this disclosure is not impaired. The terms "first," "second," etc., described above, are used to distinguish the terms to which these terms are attached, and do not limit the number or order of the terms. [Industrial Applicability]
