Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a foot massage device that mainly applies acupressure to the belly (back) of the foot.
[0002]
[Prior art]
It is known that the abdomen of the foot has concentrated acupuncture points (acupuncture points) that affect the entire body, and it is possible to identify a disease site and recover the disease site through the acupuncture point by stimulating the acupuncture point. It is also known that the feet can be massaged to promote blood circulation and recover from fatigue. In the present invention, the device for obtaining the above-mentioned effect is widely referred to as a foot massage device. Conventionally, many proposals have been made for such foot massage devices. There are various means for giving a stimulus, for example, those that apply mechanical pressing force to the foot belly (Japanese Patent Application Laid-Open No. 7-255809 “Foot Massager”, Japanese Patent Application Laid-Open No. 8-98865 “Foot Massager”) Those that give vibration over the entire foot abdomen (Japanese Patent Laid-Open No. Hei 6-218021 “Foot Massager”) No. 57438 “Air Massage Cushion and Air Massage Machine Using This”.
[0003]
Many foot massage devices that apply mechanical pressing force to the abdomen of the foot include acupressure protrusions that move up and down so as to protrude from the surface on which the foot is placed (JP-A-7-255809, JP-A-8-98865). ). A user puts his / her foot on the part where the acupressure protrusion appears, and stimulates the abdomen of the foot by the pressing force of the protruding acupressure protrusion. A foot massage device that applies vibrations to the entire abdomen of the foot applies vibrations with a small amplitude to the abdomen of the foot, thereby stimulating the entire foot and promoting blood flow to recover from fatigue. The foot massage device (Japanese Patent Laid-Open No. Hei 6-218021) of the example publication enables vibration not only in the vertical direction but also in the horizontal direction so that the vibration does not become monotonous.
[0004]
On the other hand, there are many examples of foot massage devices that apply a pressing force over the entire foot using an air cell (Japanese Patent Laid-Open Nos. 9-262261 and 10-57438). For example, in the foot massage device disclosed in Japanese Patent Laid-Open No. 10-57438, a bag-like air cell for inserting a foot is used to press the entire foot substantially evenly. Promotes blood circulation by repeatedly pressing and releasing the foot, and aims to recover. The foot massage device disclosed in Japanese Patent Laid-Open No. 9-262261 uses a huge air cell bag that wraps from the inflated shin to the thigh. In addition to these mechanical types, there are also devices that apply stimulation by moving the foot relatively, as disclosed in JP-A-9-75414.
[0005]
[Problems to be solved by the invention]
Each of the above-mentioned foot massage devices is attempting to mechanically realize a movement simulating acupressure, but none of them has been sufficiently effective. In the foot massage devices disclosed in JP-A-7-255809 and JP-A-8-98865, the amplitude of the acupressure protrusions that appear and disappear is constant, so that the amplitude of the press is excessive by a person and may cause pain instead of stimulation. It was. In addition, since the pressure of the acupressure protrusion on the foot abdomen is also a force that lifts the foot upward, it is necessary to hold the foot down or the user must shift the foot according to the position of the acupressure protrusion was there. The foot massage device disclosed in Japanese Patent Application Laid-Open No. 6-218021 has a problem in that it cannot provide sufficient stimulation to the foot, no matter how complicated the vibration is, and it is difficult to obtain a massage effect.
[0006]
A foot massage device using an air cell is excellent from the viewpoint of giving appropriate pressure without giving pain to the foot. When the pressure becomes excessive, air exerts elasticity and absorbs excessive pressing force, so there is no pain in the foot. However, unlike acupressure, because it compresses the foot over a wide range, the massage effect of stimulating the acupuncture points could not be obtained. In addition, the volume of the air cell that feeds air tends to increase, and there is a problem that it is difficult to quickly repeat a series of operations such as pressing and releasing the foot.
[0007]
Such a mechanically driven foot massage device is naturally complex in structure and expensive. As described above, if the effectiveness of the massage is low, it becomes an expensive device, and the commercial value is lowered accordingly. For this reason, a massage device having no power has been invaluable as disclosed in JP-A-9-75414. However, these devices are labor intensive for the user and are cost effective but have not yet become widespread. In view of this, a machine-driven foot massage device that does not impose any effort on the user was examined in order to develop a new machine-driven system that can give a moderate stimulus to an appropriate site and obtain a high massage effect.
[0008]
[Means for Solving the Problems]
What was developed as a result of the study was a body with the upper surface as a footrest plate, an upper massage part consisting of an upper air cell placed on the footrest board, a lower massage part consisting of a lower air cell built into the body, and a lower massage Reciprocating mechanism of each part, and each air cell and the control unit of the reciprocating mechanism, and a device for pressing the foot placed on the footrest plate from the upper and lower abdomen with the upper and lower massage parts, Consists of a pipe guide that forms a straight track parallel to the footrest plate and a screw screw that is a linear motion drive source inside the housing, and the lower massage part penetrates the pipe guide and screw screw Is stored in a moving box that is screwed, and the acupressure protrusions erected on the upper surface of the lower air cell while the screw screw rotates and reciprocates along the pipe guide. By haunt from footrest plate by repeated contractions intermittently pressing the belly of the foot, the upper massage unit and configured to press the top of the foot by expansion and contraction of the upper air cells in synchronization with infested the acupressure protrusionsIn the foot massage device, a foot detection mechanism that moves in synchronization with the lower massage part is attached to the moving box, and the foot detection mechanism is composed of a detection rod that protrudes from the footrest plate. When the foot is placed on the board, it is pushed down by the foot's belly and descends to detect the presence of the foot, and when the lower massage part moves, the detection rod will eventually come off from the toe of the foot, so a certain distance from that stage Move and stop the massage unitIt is a foot massage device.
[0009]
In the foot massage device of the present invention, since the lower massage part moves the acupressure protrusion up and down by using the expansion and contraction of the lower air cell, an appropriate stimulation can be given to the foot belly without excessive pressure. The rise of the acupressure protrusion by the air cell is weaker than the push-up by the mechanical drive, and the acupressure protrusion stops rising at the stage where the reaction force generated by the tip of the acupressure protrusion reaching the belly of the foot is balanced. In addition, since the upper air cell of the upper massage part presses the back of the foot in surface contact, when it is inflated with pressurized air of the same pressure as the pressurized air that inflates the lower air cell, the total amount of pressing force will push up the acupressure protrusion. Since the force is exceeded, the foot can be sufficiently pressed by the acupressure protrusion without being lifted.
[0010]
The movement of the lower massage part on the predetermined trajectory by the reciprocating motion mechanism has the function of displacing the stimulation position by the acupressure process along the time series, and the user can acupressure the belly of the foot over a wide range without moving the foot. Like that. The predetermined trajectory can be freely determined such as a straight line, a curved line, or a combination thereof, but a straight line extending from the toe to the toe is simple and easy to control. Examples of the reciprocating mechanism include a configuration in which a screw screw using an electric motor as a power source is screwed to a support body or the like of the lower massage portion. The movement of the lower massage part is preferably intermittent. With the above configuration, the electric motor itself is intermittently driven, or intermittentness is added to the power transmission mechanism from the electric motor to the screw screw. In addition, since it is not necessary for the acupressure protrusion to move beyond the length of the foot, a mechanism for limiting the moving range of the lower massage portion may be added as appropriate according to the size of the user's foot. The movement range of the lower massage part is a method in which the user sets the movement range electrically or mechanically in advance, or a method of detecting the foot length using a foot detection mechanism that moves in synchronization with the lower massage part. Restrict with etc.Specifically, a configuration in which a foot detection mechanism that moves in synchronization with the lower massage portion is attached to the moving box is preferable. In this case, the foot detection mechanism includes a detection rod that protrudes from the footrest plate, and the detection rod is pushed down by the foot of the foot when the foot is placed on the footrest plate to detect the presence of the foot, When the lower massage part moves, the detection rod eventually comes off from the toe of the foot, so that the lower massage part is moved by a certain distance from that stage and stopped.
[0011]
The acupressure protrusion is displaced along a predetermined trajectory, thereby bringing the effect of the acupressure to the entire foot abdomen. In this case, it is preferable to displace the acupressure protrusions composed of a plurality of protrusions provided at a predetermined interval rather than the acupressure protrusions formed of a single protrusion, because the effect of the acupressure can be applied in a wider range. Thus, when a shiatsu process is comprised by combining a some protrusion, the irritation | stimulation by a better acupressure process can be given to the belly of a foot | leg. Each protrusion can be interlocked or individually displaced. In addition, acupressure protrusions can be provided at an eccentric position with respect to the turning axis in the up-and-down movement direction so that stimulation by the acupressure protrusion is not monotonous, and the acupressure protrusion can be swung in accordance with reciprocation and up-and-down movement. In this case, with the acupressure protrusions composed of a plurality of protrusions, the arrangement relationship of the protrusions can be selected, such as arranging each protrusion around the pivot axis and arranging only a specific protrusion at an eccentric position. If the reciprocation cycle of the acupressure protrusion with respect to the predetermined trajectory is different from the turning period of the acupressure protrusion, the movement of the acupressure protrusion becomes irregular, and a timeless stimulus can be given to the foot abdomen. The pressing action by the acupressure protrusion can be exerted over a wider range.
[0012]
For the expansion and contraction of the upper or lower air cell, a three-way valve type air valve is interposed in the middle of the flow path connecting the air compressor and the upper or lower air cell, and the control unit moves the flow path of the air valve while the air compressor is always pressurized. A configuration for controlling by switching is adopted. The three-way valve type air valve switches the internal flow path by an electrical signal given from the control unit, and can supply or discharge pressurized air to the upper or lower air cell without stopping the air compressor. For example, to expand the lower air cell, the air valve is switched to a flow path connecting the air compressor and the lower air cell, and to contract the lower air cell, the flow path is switched to the flow path connecting the remaining open port of the air valve and the lower air cell. The pressing duration of the acupressure protrusion that affects the feeling of acupressure is proportional to the connection time of the flow path connecting the air compressor and the lower air cell in the air valve. In order to make the acupressure feeling of the acupressure projections by the upper and lower air cells equal to the left and right, basically one air valve is assigned to each pair of left and right air cells. One air valve is assigned to each unit.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a use state of an example of the foot massage device of the present invention, and FIG. 2 is a perspective view of the foot massage device in the same use state excluding the upper massage portion 1 and the inflated shin massage portion 2 (see FIG. 1). FIG. 3 is an internal perspective view showing a state in which the lower massage part 3 is at the origin position. In this example, the foot massaging apparatus of the present invention similarly uses a side air cell 5 (see FIGS. 9 and 10 to be described later) that repeats expansion and contraction due to the supply of pressurized air from the air compressor 4. The product structure which added the massage part 2 is taken.
[0014]
As seen in FIG. 1, the housing 6 has a substantially rectangular shape in plan view as a footrest plate 7 whose upper surface is inclined. The inflatable shin massage part 2 is pivotally attached to the lower rear edge in front of the housing 6 so as to be rotatable in the front-rear direction, and the user holds the inflatable shin from below with the foot placed on the footrest plate 7. I am doing so. The inflatable shin massage part 2 incorporates a pair of side air cells 5 and 5 (see FIGS. 9 and 10 to be described later) in an opposing relation to the inner surface of the frame-like footrest 8. The foot is pushed to the upper massage part 1 having the foot press cover 10 opened in the same plane direction as the footrest plate 7 while the heel is directed to the heel rest 9 (see FIG. 2). An upper air cell 11 (see FIGS. 5 and 6 to be described later) that expands toward the footrest plate 7 is attached to the inner surface of the foot press cover 10. As can be seen from FIG. 2, two elongated holes 12, 12 extending from the heel of the foot to the toe are provided in the footrest plate 7, and the lower massage part 3 (FIG. 2) moves from the heel of the foot toward the toe. 3) causes the acupressure protrusion 13 to appear and disappear from the elongated holes 12 and 12.
[0015]
As shown in FIG. 3, two pipe guides 14, 14 that form a linear track parallel to the footrest plate 7 are provided in the housing 6 so as to be sandwiched between the pipe guides 14, 14. Connected to the electric motor 15 as a linear motion drive sourceScrew screw 16 TheThe air compressor 4 and a control unit 17 that controls and controls each unit are incorporated. The controller 17 can be operated by the user himself / herself with a remote controller 33 connected to the outside of the apparatus by a cable. The remote control may be a wireless system, but since the user does not leave the apparatus, a wired system using a cable is preferable in order to prevent the remote control from being lost.Screw screwThe control unit 17 monitors the rotational speed of 16 using the rotary encoder 18. The lower massage part 3Screw screwIn the horizontally long moving box 19 orthogonal to 16, the lower air cell 21 having the acupressure protrusion 13 having two protrusions 20 and 20 as a set fixed to the upper surface is divided into left and right parts and housed one by one. The pipe guide 14 penetrates the moving box 19,Screw screw16 is screwed into the moving box 19. Further, in this example, when the lower massage unit 3 is returned to the origin position before the housing 6 at the start of the operation of the apparatus, the limit switch 22 for detecting the position is moved to the back of the moving box 19 and the lower massage unit 3 is moved. A rear limit switch 23 is provided on the front surface of the moving box 19 in order to reverse the direction to the reverse direction.
[0016]
Screw screwWhen 16 rotates, the lower massage part 3 moves along the pipe guides 14 and 14 in the forward direction or the backward direction. The limit of the movement range by the slide switch 34 of the remote controller 33 is set by the user before using the apparatus.Screw screwWhen 16 turns onceScrew screwSince the moving box 19 moves by the pitch width of 16, the movement of the lower massage part 3 can be finely controlled.Screw screwSince the rotational speed of 16 is monitored by the rotary encoder 18, the movement amount of the lower massage part 3 can be grasped by the rotational speed × pitch width. When the movement amount of the lower massage part 3 calculated as described above reaches a predetermined value, the control part 17Screw screwThe rotation of 16 is stopped, the lower air cell 21 is expanded, and the acupressure projection 13 is projected from the surface of the footrest plate 7. When the total amount of movement of the lower massage part 3 reaches the movement range set by the slide switch 34, the movement of the lower massage part 3 is stopped, the movement direction is reversed, or the lower massage part 3 is moved to the origin. It will be restored.
[0017]
FIG. 4 is a configuration block diagram of the main part of the foot massage device of this example. As shown in FIG. 3, the pipe extending from the air compressor 4 branches through a three-way valve type air valve 24 and is connected to the left and right lower air cells 21 and 21. That is, one air valve 24 is assigned to both lower air cells 21 and 21. In the foot massage device of this example, as shown in FIG. 4, the upper air cell 11 (see FIGS. 5 and 6 below) and the side air cell 5 (see FIGS. 9 and 10 below) are also the same as the lower massage portion 3. One air valve is assigned to each of the left and right air cells, and each is connected to an air compressor. In addition to controlling the reciprocating motion of the lower massaging unit 3 as described, the control unit 17 switches the flow path of the air valve 24 of each pipe every predetermined period, and controls the expansion and contraction of the lower air cells 21 and 21. The expansion and contraction of the air cells between the massage parts are based on the same period, and if necessary, the length or time difference between the periods can be provided.
[0018]
Specifically, the upper and lower massage parts 1 and 3 and the inflated shin massage part 2 will be described separately. 5 and 6 are sectional views showing the state of the upper and lower massage parts 1 and 3 when the footrest plate 7 is viewed horizontally, FIG. 5 is a contracted state, and FIG. 6 is an expanded state. Yes. In each figure, for convenience of explanation, only the piping system for the lower massage unit 3 is shown, but the same piping system is also configured for the upper massage unit 1. The air compressor 4 shown in this example is always operated during use of the apparatus, and when the pressure of the pressurized air exceeds a safe value due to the occurrence of a reaction force or the like, the air compressor 4 automatically becomes idle operation and no load is applied. ing. Thus, when the compressed air is exhausted from the air cells 11 and 21, even if the air valve 24 blocks communication with the air compressor 4, the air compressor 4 can be operated without stopping.
[0019]
In this example, the expansion and contraction cycles of the air cells 11 and 21 of the upper and lower massage parts 1 and 3 are the same. In each air cell 11, 21, the air valve 24 blocks the flow path with the air compressor 4, and the compressed air is released by communicating each air cell 11, 21 with the open port 26. In particular, in the lower massage part 3 of the present example, the lower air cell 21 is contracted so as to be crushed by the spring force Fs of the spring 25 urging downward (see the black downward arrow in FIG. 5) (FIG. 3 is omitted for the sake of convenience). Although the lower air cell 21 contracts only by releasing the pressurized air, the lower air cell 21 is compressed by the spring 25 in this example for the purpose of quickly immersing the acupressure protrusion 13 protruding from the footrest plate 7. In the upper massage part 1 as well, the upper air cell 11 contracts so that the foot is pushed into the foot cover 10 without difficulty.
[0020]
When the control unit 17 operates the air valve 24 to switch the flow path of each air cell 11, 21 to the air compressor 4 after a predetermined time has elapsed since the start of operation of the apparatus, the pressurized air begins to expand each air cell 11, 21. 6 is reached. The expanded upper air cell 11 presses the foot against the footrest plate 7 with the sum of the pressure Pu of the pressurized air and the contact area ΔSu (not shown) with the instep (see the white downward arrow in FIG. 6). . Further, the lower air cell 21 pushes up the acupressure protrusion 13 so as to pass through the long holes 12 and 12 of the footrest plate 7 to project the acupressure protrusion 13. At this time, if there is no foot, the upper surface of the lower air cell 21 expands until it comes close to the inner surface of the upper surface of the moving box 19 as shown on the right in FIG.
[0021]
However, when there is a foot, the acupressure protrusion 13 pushes up the foot's belly. The sum of the reaction force Fr of the foot belly (see the white down arrow in FIG. 6) and the spring force Fs (see the black down arrow in FIG. 6) is the pressure Pd of the pressurized air sent to the lower air cell 21. The expansion of the lower air cell 21 stops when the product of the contact area ΔSd (not shown) of the acupressure foot with the abdomen of the foot (not shown) is balanced, that is, the acupressure protrusion 13 rises. Stop. Although the pressures Pu and Pd of the pressurized air sent to the air cells 11 and 21 are equal, the upper air cell 11 is in surface contact with the instep of the foot, and the lower air cell 21 is in contact with the abdomen of the foot only near the upper end of the acupressure protrusion 13. Since the spring force Fs exists downward, as a result, the foot can be sufficiently stimulated by the acupressure protrusion 13 while closely contacting the footrest plate 7 without being lifted.
[0022]
When the expansion of the lower air cell 21 is stopped due to the balance of force relationship, the acupressure protrusion 13 is in a state of pushing up the foot of the foot with the pressure Pd of the pressurized air. That is, the pressing force of the acupressure protrusion 13 using the lower air cell 21 is always proportional to the pressure Pd of the pressurized air regardless of the expansion and equilibrium state of the lower air cell 21. The specific size is the product of the pressure Pd of the pressurized air and the contact area ΔSu (not shown) between the finger pressure protrusion 13 and the foot belly. Since the pressure Pd is applied to a narrow range ΔSd (not shown), sufficient stimulation can be given even if the pressure Pd of the pressurized air is small. In this way, the pressing of the acupressure protrusion 13 using the lower air cell 21 is not excessive, unlike the conventional acupressure raising of the acupressure protrusion, and can always stimulate the belly of the foot with a constant force. it can. Thus, the lower massage part 3 returns to the original position after the start of the device operation, and thereafterScrew screwWhile moving along the pipe guides 14 and 14 according to the rotation of 16, the acupressure protrusions 13 are caused to appear and disappear from the footrest plate 7 at predetermined intervals to stimulate the foot belly.
[0023]
As described above, the acupressure protrusions composed of a plurality of protrusions are based on a form in which both are interlocked and the expansion of the air cell is suppressed when one of them reaches the belly of the foot. However, if the plurality of protrusions individually protrude and press the foot belly, acupressure corresponding to the shape of the foot belly can be realized. As an implementation configuration, for example, the upper surface of the air cell is a movable surface that can be tilted in the entire circumferential direction, and the movable surface is tilted according to the pressing force against the belly of each protrusion, and the pressing force by both protrusions is as equal as possible. What to do, those that make up a plurality of protrusions or set a certain number of protrusions and assign individual air cells to each group, and those that allow the protrusions to expand and contract according to the reaction force of the foot belly , Etc.
[0024]
In the foot massage device of this example, the acupressure protrusion 13 has two protrusions 20, 20 fixed on the upper surface of the lower air cell 21, but the position of pressing or stimulating the foot belly as the moving box 19 reciprocates. As shown in FIG. 7, for example, as shown in FIG. 7, the protrusions 20 and 20 are provided at symmetrical positions across the pivot axis in the vertical movement direction to form the acupressure protrusion 27, and the acupressure is adjusted in accordance with the reciprocating and vertical movements. The protrusion 27 may be swung. In this case, the elongated hole 28 may be one.
[0025]
In the example shown in FIG. 1 and subsequent figures, a slide switch 34 is provided in the remote controller 33 as an electrical setting mechanism for limiting the movement range of the lower massage part 3. Instead of the slide switch 34, for example, a setting dial 35 of the same electrical setting mechanism may be provided on the upper surface of the foot press cover 10. Further, as shown in FIG. 8, a detection rod 36 attached to the moving box 19 may be protruded from the long hole 12 as a foot detection mechanism that moves in synchronization with the lower massage portion 3. The detection rod 36 is pushed down by the foot belly when the foot is placed and detects the presence of the foot. If the lower massage part 3 moves, the detection rod 36 will eventually come off from the toe of the foot, so that the lower massage part 3 is moved by a certain distance from that stage and stopped. In the example of FIG. 8, the detection rod 36 is viewed using the long hole 12 through which the acupressure protrusion 13 moves, but a long hole dedicated to the detection rod 36 may be provided separately. In addition, a detection rod having a roller attached to the upper end may be used instead of a simple rod shape so as not to cause movement resistance of the lower massage portion 3. In addition, the length of the foot can be automatically measured by a non-contact sensor (such as an optical sensor) to limit the movement range of the lower massage part.
[0026]
In the foot massage device of this example, in addition to the upper and lower massage parts 1 and 3 for stimulating the abdomen of the foot, the inflated shin massage part 2 using the side air cell 5 is configured. 9 and 10 are cross-sectional views of the inflated shin massage part 2, FIG. 9 shows a state in which the side air cell 5 is deflated, and FIG. 10 shows a state in which the side air cell 5 is inflated. The inflatable shin massage part 2 has an upper and lower massage parts 1 and 3 that press the instep and abdomen with each air cell 11 and 21 as a pair, whereas a pair of sides arranged in a substantially opposite positional relationship. Gently squeeze the user's foot inflatable shin with the air cell 5,5. The side air cell 5 is covered with a cloth cover 29, and a rubber 30 is attached to the edge of the footrest 8 to enhance safety during use. The user inserts the shin into the recess 31 of the footrest 8 as shown in FIG. 9 with the side air cell 5 deflated. In this state, there is a margin between the side air cell 5 and the inflated shin, and of course, the inflated shin is not pressed by the side air cell 5.
[0027]
When the air compressor 4 (see FIG. 3 and the like) starts to operate and the air valve 24 (see FIG. 4) for the side air cell 5 connects the flow path between the air compressor 4 and the side air cell 5, each air cell 5 expands. start. In this example, a rubber piece 32 is attached to one side of the side air cell 5 so that the shins can be sandwiched substantially symmetrically from the left and right by the side air cells 5, 5, and the sectional shape of each side air cell 5 when expanded is shown. It is regulated. As shown in FIG. 10, the side air cells 5 that have been sufficiently inflated are squeezed so as to sandwich the inflated shin from the left and right directions. Also in the inflatable shin massage part 2, the expansion of the side air cell 5 using the pressure of the pressurized air stops the expansion due to the balance with the reaction force from the stage where the inflatable shin is appropriately pressed. It is not a pressing force.
[0028]
In the foot massage device of this example, the expansion and contraction of each air cell of the upper, lower, and inflated shin massaging portions is controlled by each air valve by one air compressor. Since each air valve can be easily operated by the control unit, the device configuration is simple, and the weight of the foot massage device can be reduced. And the point which can obtain moderate irritation | stimulation with high effect as a foot massage apparatus is the biggest effect of this invention.
[0029]
【The invention's effect】
According to the present invention, it is possible to provide a foot massage device that can give an appropriate stimulus to an appropriate site. As shown in the embodiment, the pressure using the air cell can be easily and precisely controlled by switching the flow path in the three-way valve type air valve by interposing in the middle of the piping for distributing the pressurized air. If a control pattern corresponding to the stage is incorporated, an appropriate foot massage can be performed for each user. In addition, the press using the air cell is never excessive due to the balance with the reaction force, so that the foot is not damaged. As described above, the foot massage device of the present invention eliminates the drawbacks of the conventional products and realizes the provision of a device having a more natural acupressure feeling.

By infested intermittently pressing the belly of the foot from the placing plate, the upper massage unit the acupressure protrusions foot massaging apparatus configured to press the top of the foot by expansion and contraction of the upper air cells in synchronization with infested In
A foot detection mechanism that moves in synchronization with the lower massage part is attached to the moving box. The foot detection mechanism is composed of a detection rod that protrudes from the footrest plate, and the detection rod is placed on the footrest plate. When the lower massaging part is pushed by the foot belly at the stage and detected, and the lower massage part moves, the detection rod will eventually come off the toe of the foot, so the lower massage part is moved by a certain distance from that stage. A foot massage device characterized by being stopped .
