Description

Massage module {MASSAGE MODULE}

The present invention relates to a massage device, and more specifically, to a massage module that is installed on a massage chair to be able to move back and forth a certain distance by a transfer device and performs a massage function while applying vibration or pressure to parts of the user's body. .

Recently, as the standard of living has increased and the population is aging, the number of people suffering from muscle paralysis or muscle pain due to lack of exercise and stress is increasing, leading to increasing interest in massage devices.

Accordingly, beyond simple massage functions, massage devices with various functions and high performance have emerged to meet the needs of users.

A chair-type massage device (hereinafter referred to as a 'massage chair') is a mechanical massage module and/or an inflatable air cell module for each part of the body that is in direct contact with the chair, such as the neck, back, waist, buttocks, arms, legs, and feet. It is designed to be used for massage.

Massage chairs are generally equipped with an elevating massage module on the backrest, so that the elevating massage module moves up and down from the neck to the waist or thighs, performing a massage action of rubbing and tapping the body, thereby lifting the neck to the waist of the person sitting on the massage chair. Alternatively, it relieves fatigue by providing acupressure to the thighs and performs functions such as muscle relaxation, spinal correction, and massage.

The elevating massage module, which is formed on the backrest of the massage chair, has a pair of massage chair brackets that move left and right and forward and backward by a driving actuator containing a motor, and is placed on the left and right, and the user's body is placed on each massage chair bracket. It has a structure in which a plurality of massage elements (for example, rollers or balls) that perform kneading or tapping operations are arranged up and down.

Recently, massage modules are configured so that the position of the massager can be varied as the massager bracket rotates in the forward and backward directions in order to implement various massage movements on a wider body part than before, such as the user's neck and shoulders.

However, as described above, when the massager bracket of the massage module rotates forward and backward and the position of the massager changes in the forward and backward directions, some massager heads protrude further forward than before, and as a result, they protrude further forward than other parts of the body, such as the scapula of the shoulder. Pain occurs because strong force is applied to the part that protrudes further back.

Republic of Korea Patent No. 10-1730782 Republic of Korea Patent No. 10-2129574 Republic of Korea Patent No. 10-1146851

The present invention is to solve the above problem, and the purpose of the present invention is that in the process of massaging the body while the massage module moves back and forth along the massage chair, the massage element (e.g. roller or ball) of the massage module moves to a body part ( For example, it provides a massage module that does not cause pain in the shoulder blade area.

A massage module according to the present invention for achieving the above object includes a module base that moves up and down in the massage device by a transfer device; a massage drive unit installed on the module base to provide at least one of vibration for massaging the body, linear motion, rotational motion, and power for adjusting the massage position; A massage chair bracket rotatably connected to the massage drive unit in the forward and backward directions about the hinge axis; An elastic member elastically connecting the massage chair bracket to the massage drive unit; And, an upper sampler, a middle sampler, and a lower sampler that are installed at the upper, middle, and lower portions of the sampler bracket, respectively, and apply pressure to the user's body. The center of the middle sampler is the center of the hinge axis. It can be placed a certain distance above.

According to one form of the present invention, when viewed from the front of the massage module, the upper massager and the lower massager are arranged on a line extending in the vertical direction with respect to the ground, and the middle massager is connected to the upper massager and the middle massager. It is preferable that they are arranged to be spaced apart at a certain distance outside of the line connecting the lower sample elements.

Additionally, in the initial state before the sample member bracket rotates about the hinge axis by an external force, the front end of the middle sample member may be arranged to be spaced a certain distance rearward from the front end of the upper sample member.

The diameter of the middle sample element may be smaller than the diameter of the upper sample element.

Additionally, the diameter of the lower sample element may be the same as the diameter of the middle sample element.

The vertical distance (L1) between the center of the middle sampler and the center of the hinge axis is preferably between 30% and 50% of the vertical distance (L0) between the center of the upper sampler and the center of the hinge axis.

According to the present invention, the massage module massages the user's head and neck from the top of the massage chair and then descends, and then the upper massage chair receives a load backward from the shoulder area, causing the massage chair bracket to rotate around the hinge axis. Since the amount of the middle massager protruding forward is minimized, it is possible to prevent pain caused by a strong blow to the user's shoulder blade area by the middle massager.

In addition, since the massage module consists of three massagers on the left and right, an upper massager, a middle massager, and a lower massager, it is possible to perform a variety of massage modes in a wider range than before.

The embodiments described in this specification and the configurations shown in the drawings are only preferred examples of the disclosed invention, and at the time of filing this application, there may be various modifications that can replace the embodiments and drawings in this specification.

Hereinafter, the massage module will be described in detail according to the embodiments described below with reference to the attached drawings. In the drawings, like symbols represent like components.

Referring to FIG. 1, the massage chair 1 forms an area for accommodating at least a portion of the user's body, a body massage part 2 that massages the user's body, and a body massage part 2 that massages the user's legs. It may include a leg massager performing massage.

The body massage unit 2 is provided with a backrest 2a and a seat 2b so that the user can comfortably lean the back and head while sitting, and the user is inside the backrest 2a and the seat 2b. The massage module 100, which can massage body parts, that is, from the shoulder area to the back, waist, buttocks, thighs, etc., is configured to move along the guide rail 5 by a transfer device.

2 to 7, the massage module 100 includes a module base 110 installed in the massage device, and at least one of vibration for massaging the body, linear motion, rotational motion, and power for adjusting the massage position. A massage drive unit that provides one or more power, a massage chair bracket 130 connected to the massage drive unit, an elastic member 145 that elastically connects the massage chair bracket 130 to the massage drive unit, and a massage chair bracket 130. It includes an upper massager 151, a middle massager 152, and a lower massager 153 that are installed at the upper, middle, and lower ends, respectively, and apply pressure to the user's body.

The module base 110 moves up and down by a transfer device inside the backrest of the massage chair 1. A plurality of massage units 100 are symmetrically installed in front of the module base 110, and an upper massager 151, a middle massager 152, and a lower massager 153 are installed at the rear of the module base 110. By vibrating back and forth or rotating in a linear or circular or oval shape, a tapping massage or kneading massage is performed, or the user's shoulder position is moved a predetermined distance in the front-to-back direction to determine the user's front-to-back position (depth). ) A massage drive unit that provides power to adjust is installed. This massage driving part can be configured by applying a massage driving part that provides power for kneading and tapping motions of the massage chair and adjusting the position (depth) of the massage chair from the massage module of a known massage chair.

For example, the massage driving unit may include a kneading motor 121 and a tapping motor (not shown), and a power transmission mechanism that transmits the power of the kneading motor 121 and the tapping motor (not shown) to the sampler bracket 130. there is. The power transmission mechanism can be constructed by appropriately combining cams, gears, timing belts, linkage devices, etc.

Additionally, if the module base 110 moves up and down to perform massage while the position of the massager is fixed, the massager may feel pain due to a strong blow to the shoulder area depending on the position of the user's shoulder. Accordingly, by adjusting the anteroposterior position (depth) of the massager according to the user's shoulder position, an effective massage operation can be performed by preventing excessive blows to the shoulder area. To adjust the depth of the massager, a position adjustment motor 124 is used. and a shaft 125 for transmitting the power of the position adjustment motor 124 to the specimen bracket 130, a position adjustment pinion gear 126 coupled to the shaft 125, and a frame constituting the power transmission mechanism. It may include a position adjustment rack gear 127 that is installed at the top and meshes with the position adjustment pinion gear 126.

Therefore, when the position adjustment motor 124 operates and the shaft 125 rotates, the position adjustment rack gear 127 meshed with the position adjustment pinion gear 126 moves forward or backward a certain distance, and accordingly, The sample bar bracket 130 moves forward or backward a certain distance so that the forward and backward positions (depth) of the upper specimen 151, the middle specimen 152, and the lower specimen 153 can be adjusted.

The sample bar bracket 130 is made of an approximately 'V' shaped metal plate, and is connected to the massage drive unit through a connection bracket 140 to receive power and move back and forth and left and right. The middle part of the sample bar bracket 130 is rotatably connected to the connection bracket 140 via the hinge axis 135, and is elastically connected to the connection bracket 140 through the elastic member 145 to protect the user's back. According to the curvature of the body, the anteroposterior positions of the upper sampler 151, middle sampler 152, and lower sampler 153 are flexibly changed while rotating flexibly in the forward and backward directions around the hinge axis 135. Allows you to perform massage.

In addition, a spring connection pin 132 is provided at the lower part of the sample bar bracket 130 to connect the elastic member 145. The elastic member 145 may be a tension coil spring that provides an elastic force to pull the lower part of the sample bar bracket 130 backward.

The upper massager 151, the middle massager 152, and the lower massager 153 are formed in the form of rollers or balls with a predetermined diameter, and the outer skin is made of rubber or rubber to gently massage the user's body. It may be made of an elastic resin material such as silicon, or it may be made of hard plastic, ceramic, or minerals such as jade or germanium. In this embodiment, the upper sampler 151, the middle sampler 152, and the lower sampler 153 are in the form of rollers, so that their centers can rotate at the upper, middle, and lower ends of the sampler bracket 130, respectively. It is connected well. The middle sampler 152 and the lower sampler 153 have generally the same diameter, and the diameters of the middle sampler 152 and the lower sampler 153 may be smaller than the diameter of the upper sampler 151. .

As shown in FIG. 4, when the massage module 100 moves downward while massaging the user's neck and shoulder area at the upper end of the guide rail 5 of the massage chair 1, the upper massage element 151 at the top moves to the neck. The specimen bracket 130 rotates counterclockwise in the drawing around the hinge axis 135 due to the user's load so that it moves from the shoulder area and touches the top of the shoulder area. At this time, the middle massager 152 touches the scapula, which is the most posteriorly protruding part of the user's shoulder area. If the middle massager 152 protrudes forward too much, it hits the scapula strongly, causing pain.

Accordingly, when the sample bar bracket 130 rotates around the hinge axis 135, the upper specimen bar 151 moves backward and the lower specimen bar 153 moves forward, the middle specimen bar 152 moves forward. In order to minimize the amount of damage, it is preferable that the center of the intermediate specimen 152 is placed a certain distance above the hinge axis 135, as shown in FIG. 5. If the center of the middle sampler 152 is the same as or disposed below the hinge axis 135, the distance that the middle sampler 152 moves forward when the sampler bracket 130 rotates counterclockwise in the drawing increases and hits the user's shoulder blade strongly, causing pain. However, if the center of the middle sampler 152 is placed a certain distance above the hinge axis 135, the distance that the middle sampler 152 moves forward when the sampler bracket 130 rotates counterclockwise in the drawing is can be minimized.

At this time, the vertical distance (L1) between the center of the middle sample element 152 and the center of the hinge axis 135 is the vertical distance (L0) between the center of the upper sample element 151 and the center of the hinge axis 135. It is preferably between 30% and 50%. For example, when the vertical distance (L0) between the center of the upper sample element 151 and the center of the hinge axis 135 is 100 mm, the vertical distance between the center of the middle sample element 152 and the center of the hinge axis 135 The distance (L1) is preferably 30 mm to 50 mm. If the vertical distance (L1) between the center of the middle sample element 152 and the center of the hinge axis 135 is 30% of the vertical distance (L0) between the center of the upper sample element 151 and the center of the hinge axis 135 If it is less than %, the amount of forward movement of the middle massager 152 increases, which may cause pain in the scapula. If it is larger than 50%, the gap between the upper massager 151 and the middle massager 152 becomes too narrow. The disadvantage is that the massage range is reduced.

In addition, in order to provide a wide massage range while minimizing the amount of forward movement of the intermediate massager 152, the intermediate massager 152 is in its initial state before the massager bracket 130 rotates about the hinge axis 135 by external force. ) It is preferable that the front end of the upper sample element 151 is spaced a certain distance apart from the front end of the upper sample element 151 or is located on the same line.

And, as shown in FIG. 6, in order to massage a wider area of the body using the middle massager 152, the upper massager 151 and the lower massager 153 are used when viewed from the front of the massage module 100. is disposed on a line extending in the vertical direction with respect to the ground, and the middle sample element 152 is located a certain distance outward with respect to the line connecting the upper sample element 151 and the lower sample element 153. Can be placed spaced apart. For this purpose, a bracket shaft 131 to which an intermediate sampler 152 is rotatably connected to the middle portion of the sampler bracket 130 is formed to extend outward, and an intermediate sampler 152 is formed at the outer end of the bracket shaft 131. (152) is connected. Here, a protrusion 133 protruding in the front direction of the sample bar bracket 130 is formed between the upper end of the specimen bar bracket 130 and the hinge axis 135, and the protrusion 133 is located on the inner side of the bracket shaft 131. The ends may be joined.

In this way, when the bracket shaft 131 is installed to extend outward between the upper end of the sampler bracket 130 and the hinge axis 135, and the intermediate sampler 152 is connected to the outer end of the bracket shaft 131, , when the sample bar bracket 130 rotates and swings in the direction of the arrow shown in FIG. 6, that is, when it swings in the left and right lateral directions, the middle sample bar 152 is connected to the upper specimen bar 151 and the lower specimen bar ( 153), there is an advantage in that the massage range can be expanded by increasing the rotation radius of the middle massage element 152 because it swings in the left and right lateral directions at a position spaced a certain distance outwardly. In other words, when the intermediate sample bar 152 is installed adjacent to the outer surface of the sample bar bracket 130, the intermediate sample bar 130 rotates in the direction of the arrow shown in FIG. 6 and swings in the left and right lateral directions. The rotation radius of the ruler 152 is small, so the massage range is small. However, as shown in FIG. 6, a bracket shaft 131 having a predetermined length is installed in the middle of the massage ruler bracket 130 to extend outward, and the bracket shaft is When the middle massager 152 is connected to the outer end of (131), when the massager bracket 130 swings in the left and right lateral directions, the rotation radius of the middle massager 152 increases, thereby increasing the massage range. It will happen.

Meanwhile, as described above, the lower sampler 153 has a smaller diameter than the upper sampler 151 and is disposed to protrude slightly further forward than the upper sampler 151 and the middle sampler 152. As shown in FIG. 7, the structure of the massager 153 provides the advantage of improving the massage sensation in the user's gluteus maximus and gluteus medius areas and enabling sophisticated massage.

The massage module 100 of the present invention can provide a massage function in a wide range to the user's body by arranging three massage elements in the vertical direction on each of the left and right sides of the module base 110, where three massage elements each The middle sampler 152 disposed in the middle has a smaller diameter than the upper sampler 151, and its center is located at a certain distance above the hinge axis 135 of the sampler bracket 130. Therefore, when the massage module 100 massages the user's head and neck from the top of the massage chair and then descends, and the upper massage chair 151 receives a load backward from the shoulder area, the massage chair bracket 130 moves along the hinge axis ( 135), it rotates counterclockwise in the drawing. At this time, the amount of the middle sampler 152 protruding forward is minimized, so that a strong blow is applied to the user's shoulder blade area by the middle sampler 152. can be prevented.

In particular, when performing a massage mode in which the position of the massager bracket 130 is moved forward using the position adjustment motor 124 of the massage drive, the pressure on the shoulder blade by the middle massager 152 has a greater effect as described above. Therefore, the relative positions between the middle sampler 152, the upper sampler 151, and the hinge axis 135 should be considered more important.

Although the preferred embodiments of the present invention have been described above, various changes, modifications, and equivalents may be used in the present invention. It is clear that the present invention can be equally applied by appropriately modifying the above embodiment. Accordingly, the above description does not limit the scope of the present invention, which is defined by the limitations of the claims below.
