Description

Belt Type Massager [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a belt-type massager for massaging using a plurality of belts. More particularly, the present invention relates to a belt-type massage machine in which a muscle portion to be massaged is wrapped with a plurality of belts, and then the action of slowing down the belt is repeated to massage the muscle portion.

Our blood circulates through the arteries and veins back to the heart. In other words, the arterial blood is sent to the muscles by the force of the heart, and the blood of the veins returns to the heart by compressing the veins as the muscles around the veins contract and relax. For reference, if you do not exercise your muscles, you can regurgitate the blood, and there is a valve inside the vein to prevent backflow of blood.

Therefore, patients who lack muscle motility, wheelchair users, or occupations (such as office workers) whose occupational use is restricted are susceptible to diseases such as varicose veins because their ability to return blood from the veins is weak. Therefore, it is desirable that these people massage the muscles frequently, such as calves, thighs, or arm muscles, so that the blood of the veins is smoothly circulated.

There are many types of massagers that are suitable for massaging the arm, thigh, or calf muscles.

For example, Korean Patent Registration No. 10-1245189 and Korean Registered Utility Model No. 20-0446318 disclose a roller-type massager applied to a calf muscle, wherein the massage space in which the calf portion is accommodated is formed to the left and right And the calf is accommodated in the massage space, and then the rollers installed in the left and right massage chambers are moved up and down to massage the calf muscles.

Korean Patent Laid-Open Publication No. 10-2008-0089686 also discloses a pneumatic massage machine applied to a calf muscle. This type of massage machine is designed to wrap a calf portion in a plurality of air bags and to supply air to the air bags with an air pump The muscles are pushed or relaxed by discharge, and massage is performed.

However, since the massagers in the related art are installed in a certain place and massage the user by inserting a muscle part (calf) to be massaged by the user, the movement of the user is limited during use. That is, the conventional massage machines have a problem that it is difficult for the user to perform activities such as movement and work while wearing the massage machine to massage the massage machine.

In addition, the roller-type massager has a complicated mechanism for driving the roller, which makes it difficult to manufacture and increase the manufacturing cost. In the case of a pneumatic massage machine, an air pump for supplying high-pressure air should always be provided. However, there is a problem in that the massager is not portable or portable due to the weight and size of the air pump.

The number of lines displayed on the belt length display section 36 is not necessarily limited to six, and the designer can add and display it as necessary.

In this embodiment, three pressure belts are provided at predetermined intervals, but the number of pressure belts can be suitably increased or decreased by the designer.

The configuration of the casing 10 will be described in detail with reference to Figs. 1 and 5. Fig.

As shown in Fig. 1, the casing of the present embodiment is constituted by an outer casing 11 positioned outward when worn on a muscle portion to be massaged and an inner casing 12 contacting the muscular portion, and the outer casing 11 And the inner casing 12 are connected to each other, the inside of the casing is formed as an empty space.

A battery 50 and a control unit 60 connected to the driving unit 20 may be installed in the casing and the casing may be connected to the control unit 60 to control the speed of the motor. (Not shown) and a display (not shown) for indicating the operating state of the device may be provided.

As shown in Fig. 1, at one side of the inner casing 12, a belt entrance 13 is provided by the number of pressing belts. The belt entrance 13 is a slot formed in the casing so that one end of the pressure belt coupled to the motion switching member 25 can enter and exit the inside and the outside of the casing.

As shown in FIG. 5, a belt fixing hole 14 is formed on a surface of the outer casing 11 so as to be engaged with the belt fixing hole 34 of the pressing belt. In this embodiment, the belt fastener 14 is formed of Velcro tape.

5 (a), a belt adjusting reference line 15 is formed on the surface of the outer casing 11 on which the belt fastener 14 is installed.

In this embodiment, the markings of the belt control reference line 15 shown in FIG. 5 (a), the engaging projection position indicator 35 shown in FIG. 3, and the belt length indicator 36 are formed by straight lines. It is also possible to use means such as arrows, dots, or protrusions instead of following lines. The belt control reference line 15 allows adjustment of the installation length of the pressure belt in response to the markings displayed on the belt length indicator 36 of the pressure belt in order to adjust the belt installation length.

The fastening belt of this embodiment includes a first fastening belt 70a provided on the upper portion of the casing and a second fastening belt 70b provided on the lower portion of the casing. Here, the terms 'upper' and 'lower' of the casing mean a portion corresponding to the upper portion of the casing and a portion corresponding to the lower portion, respectively, when the belt-type massage machine is mounted on the calf as shown in FIG.

Fig. 1 shows a fixing belt mounting portion 16. The fixing belt mounting portion 16 of this embodiment forms a protrusion having a rectangular cross-section on the inner casing 12. Fig. And a hole is formed in the projecting portion so that the inside and the outside of the casing communicate with each other.

In this embodiment, after the one end of the fixing belt is inserted into the hole formed in the fixing belt mounting portion 16, the fixing belt may be completely fixed to the fixing belt mounting portion 16 using an adhesive. Of course, the means for fixing one end of the fixing belt to the fixing belt mounting portion 16 is not limited to the above-mentioned configuration using the hole and the adhesive, and all known constituent means capable of fixing one end of the fixing belt to the casing Can be used.

In this state, the muscular part to be massaged with the fixed belt is surrounded, and then the other end of the fixing belt is coupled to the surface of the outer casing 11 as shown in FIG. The configuration for such engagement can be used as it is for the coupling structure between the belt fastener 34 of the pressing belt 30 and the belt fastener 14 of the outer casing 11 described above.

Hereinafter, the operation of the belt-type massage device 100 according to the embodiment of the present invention will be described with reference to Figs. 4 to 6. Fig.

Referring to FIG. 6, a method of mounting the belt-type massage device 100 of this embodiment on a muscle portion (for example, a calf) to be massaged with a fixing belt is as follows.

First, the inner casing 12 is brought into close contact with the shank. In this state, the first fixing belt 70a, one end of which is fixed to the belt mounting portion 16 of the casing, is put on the calf, and the other end of the first fixing belt, which is not fixed to the outer surface of the outer casing 11, .

Then, the second fixing belt 70b at the bottom of the casing is wound around the calf and fixed in the same manner as the first fixing belt 70a.

Accordingly, the belt-type massage device 100 is mounted on the calf with only the fixing belt, and the belt-type massage device 100 can be mounted on other muscles such as the arm or the thighs in the same manner.

When the belt-type massage device 100 is mounted on the muscle part to be massaged with the fixing belt, the pressure belt 30, which acts as a massage, is wound around the muscle part. This process will be described in more detail. When the pressurizing belts are engaged with the engaging projections 27 of the drive unit 20, the pressurizing belts from the first pressurizing belt 30a to the third pressurizing belt 30c, And then the belt fixing holes 34 of the pressure belts are engaged with the belt fixing holes 14 provided on the outer casing 11.

When the pressure belt is installed, the power source of the belt-type massage device 100 is turned on to drive the motor M of the driving unit 20. [ Accordingly, when the driving shaft 21 connected to the motor rotates, the worm 22 formed on the driving shaft 21 also rotates, so that the worm gear 23 held by the worm can be rotated. When the worm gear is rotated, the driven shaft 24 connected to the center of the worm gear rotates along with the rotation arm 26 and the engaging protrusion (not shown) formed at the end opposite to the position of the worm gear 23 on the driven shaft 24 27) are also subjected to circular motion.

Since the engaging projection connecting portion 31 of the pressing belt is engaged with the engaging projection 27, when the engaging projection is circularly moved, the end of the pressing belt is pulled into the casing and reciprocated. In other words, as in the case of the second pressing belt 30b shown in Fig. 4, the end of the engaging projection 27 is pulled deeply into the casing by the circular motion, and the engaging projection 27, like the third pressing belt 30c, The end portion is moved toward the belt entrance 13 by the circular motion of the belt 13, thereby making the reciprocating motion loosened and delayed.

When the end portion is pulled toward the inside of the casing as in the case of the second pressing belt 30b, the pressing belt presses the muscles of the wrapping portion. As the third pressing belt 30c, the end portion is moved toward the belt entrance 13, , The pressure acting on the muscles and veins of the portion where the pressure belt is wrapped is delayed. In this way, the pressurizing belts repeatedly pressurize and relax on the muscular part to generate a massage effect, and smooth the circulation of the venous blood.

However, when the pressurizing belts are set in the same direction and the pressures applied by the respective pressurizing belts to the muscular parts are all set to the same, when the film-like massager is operated, the pressures at which the pressurizing belts press the muscular parts are all different.

This is because the initial positions of the end portions where the pressing belts are engaged with the pressing projections 27 are all different as shown in Fig.

In other words, when the belt-type massager starts operating in the state shown in Fig. 4, the third pressing belt 30c is gradually pulled inwardly into the casing, and the second pressing belt 30b is in the end position The end of the first pressing belt 30a is pulled toward the inside of the casing and then moved back to the belt entrance 13 gradually.

Therefore, when the pressure belts are first wound around the muscles to be massaged, the pressure belts are turned on so that the pressure intensities to tighten the muscles are all the same, ie, the pressure is such that the user feels a moderate pressure. The following problems arise.

First, during the operation of the massage machine, the muscles to which the third pressing belt 30c is clamped will have substantially higher compressive strength than the initially applied compressive strength, so the user will feel inconvenience due to excessive compressive strength.

In the case of the second pressurizing belt 30b, during operation of the massager, only a substantially lower compressive strength than the compressive strength initially applied to the muscular part by the second pressurizing belt will act, so that the user will have difficulty feeling the massage effect will be.

In the case of the first pressing belt 30a, since the pressing strength that moves upward and downward will act on the basis of the pressing strength initially applied to the tightening muscle portion, the user can experience a proper massage effect.

As a result, when the belt-type massager of this embodiment is operated as described above, the massage effect can not be achieved properly if all of the three pressure belts operate in different pressure ranges.

Therefore, when the belt-type massage device 100 of the present invention is first attached to the muscles to be massaged, the position of the end portions of the engaging projections 31 of the first to third pressing belts 30a to 30c , It is necessary to adjust the pressing force to be different for each pressure belt so that the three pressure belts all operate in the same pressure range when the belt type massage machine operates.

4, if the number at the position of the belt entrance 13 formed in the inner casing 12 is 2, as in the case of the third pressurizing belt 30c, the third pressurizing belt 27, It means that the end portion is moved to a position close to the belt entrance 13 and therefore it can be seen that when the massage device starts to operate, only the third pressure belt 30c will be subjected to substantially higher pressures than now, The initial compressive strength of the third pressurizing belt 30c should be set weakly (i.e., the muscle portion is weakly stretched with the third pressurizing belt).

For the same reason, if the number at the position of the belt entrance 13 is 0, as in the case of the second pressing belt 30b, the initial pressing strength of the second pressing belt 30b is set strongly. If the number is 1 as in the case of the first pressing belt 30a By setting the pressing strength of the one pressing belt 30a to a medium level, it is possible to keep the pressing strengths acting on the three pressing belts in the same range in the subsequent operation of the massage machine.

Here, a method of setting the intensity of the pressing force acting on the pressing belts 30 will be described with reference to Fig. 5 (a).

5 (a), the belt length display portion 36 of the pressing belt 30 is formed with lines marked with numbers 1 to 6 for adjusting the belt installation length.

4, since the number at the position of the belt entrance 13 of the second pressing belt 30b is zero, the pressing strength of the second pressing belt 30b is set to be high at the time of initial mounting (i.e., Stretch strongly with a belt).

When the number 6 of the belt length indicating portion 36 comes to the belt control reference line 15 when the second pressing belt 30b is wound around the muscle portion in a situation where the user confirms the number 0 at the position of the belt entrance 13 If the user feels a proper compression strength, the number 5, which is smaller than the number 1, is pulled toward the belt control reference line 15 to reduce the length of the belt that surrounds the muscular part, thereby strongly setting the compression strength.

On the other hand, if the number of the third pressing belt 30c seen at the position of the belt entrance 13 is 2, the pressing strength should be set weak when the third pressing belt 30c is wound around the muscular part to be massaged.

That is, in the case of the third pressing belt 30c, if numeral 2 of the belt length indicating portion 36 comes to the belt adjusting reference line 15, if the user feels a proper pressing strength, ) To increase the length of the belt that surrounds the muscular part, thereby setting the compression strength weakly.

Next, in the case of the first pressing belt 30a, since the number at the position of the belt entrance 13 is 1, when the user presses the first pressing belt 30a on the muscle part to be massaged, .

When the pressure intensities of the pressure belts are set to be different from each other as described above, when the belt type massager is operated, the three pressure belts will all operate in the same compressive strength range, so that massaging can be effectively performed.

The embodiments of the present invention described above and shown in the drawings should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention in various forms. Therefore, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
