Fig. 6 is a front view of a main portion for explaining the internal configuration of a calf portion in a massage chair according to an embodiment of the present invention, Fig. 7 is a sectional view taken along the line AA of Fig. 6 And FIG. 8 is a rear perspective view of the main part for explaining the internal configuration of the calf part in the massage chair according to the embodiment of the present invention. FIG. 10 is a perspective view of a roller module including a massage roller and a roller bracket in a massage chair according to an embodiment of the present invention, and FIG. 11 is a perspective view Fig. 6 is a front perspective view of a roller bracket in a massage chair according to an embodiment of the present invention.

As shown, the calf portion includes a casing 110, a support frame 120, a driving motor 130, a lifting belt 150, a roller bracket 160, and a massage roller 170 .

The casing 110 has a receiving portion 111 for receiving a user's calf as described above. The massage roller (170) is inserted into the receiving part of the casing (110) in a protruding form so that the user can press and calm the user 's calf. In the case of the casing 110, the casing 110 includes an inner portion 110a that forms most of the outer shape, and an outer portion including the cover 110b and the like so as to surround the outer sides of the inner portion 110a and accommodate various components.

The support frame 120 includes a vertical frame 121 rotatably supporting the driving gear 141 and the driven gear 142 inside the casing 110 and a horizontal frame 121 extending from the lower end of the vertical frame 121 And a horizontal frame 122 extending to the vertical frame 121 to support the vertical frame 121. Here, the vertical frame 121 includes a guide bar 125 formed in a lengthwise direction on the left side and on the postal side, respectively. The guide bar 125 serves to guide the extended portion of the roller bracket 160 to be slidably and vertically slidable. The upper horizontal bar 123 and the lower horizontal bar 124 are provided at upper and lower ends of the vertical frame 121.

The driving motor 130 is installed in the vertical frame 121 in the casing 110 to provide a driving force for lifting and lowering the massage roller 170. As shown in FIG. 8, the driving force of the driving motor 130 is transmitted to the massage roller 170. The driving force of the driving motor 130 is transmitted to the horizontal rotating shaft 145 A driving gear 141 coupled to both ends of the horizontal rotation shaft 145 to transmit a driving force to the lifting belt 150 and a driving gear 141 coupled to the driving gear 141, (142).

The lifting and lowering belt 150 converts the rotational force of the driving gear 141 into a vertical motion and transmits the vertical motion to the roller bracket 160. To this end, the lifting and lowering belt 150 is vertically connected to the driving gear 141 and the driven gear 142 while being positioned on the left side and the postal side of the casing 110, respectively. Here, the elevating belt 150 has a tooth cog which is engaged with the driving gear 141 and the driven gear 142 on the inner side. When the lifting and lowering belt 150 is provided with teeth like the timing belt, the driving force can be transmitted more stably and the coupling with the roller bracket 160 can be stably achieved without the influence of the slip. The lifting and lowering belt 150 forms a constant trajectory connecting the driving gear 141 and the driven gear 142 so that the roller module including the roller bracket 160 and the massage roller 170 can be lifted and lowered.

The roller bracket 160 plays a pivotal role in coupling the massage roller 170 to the lifting belt 150 to implement the lifting operation of the massage roller 170. The roller bracket 160 includes a coupling portion formed of a front coupling portion 161 and a rear coupling portion 162 and coupled to a point located forward of the lifting belt 150, An upper extension 163 and a lower extension 164 coupled to the coupling portion and coupled to the upper portions 163 and 164 to rotatably support the massage roller 170 by a rotation shaft 166, And a roller supporting portion 165. In the case of the roller supporting portion 165, since the width of the upwardly extending portions 163 and 164 is wide, the overall shape of the roller bracket 160 is formed into a T shape. It is preferable that the upwardly extending portions 163 and 164 are formed after the front side portion 164 and the rear side portion 163 are separately manufactured and then joined together so that they can be slidably engaged with the guide bar 125. [ It is for this reason.

Here, it can be noted that the upwardly extending portion is formed to be long in the upward direction from the coupling portion, and the massage roller 170 is installed at the upper end thereof. According to such a configuration, the massage roller 170 can be positioned further upward than the trajectory drawn by the lifting belt 150, so that the massage roller 170 can reach the upper end of the user's calf. Therefore, the massage roller 170 can completely press the entire upper part of the user's calf despite the limitation of the installation area where the lifting and lowering belt 150 can be installed.

The front coupling part 161 and the rear coupling part 162 of the roller bracket 160 are coupled to each other while pressing the elevating belt 150 on the outside and inside of the elevating belt 150, And protruding ribs 161d for reinforcing the pressing force against the lifting belt 150 in correspondence with each other in a protruding form on the facing surface. The projecting ribs 161d also serve to reinforce the structural strength of the roller bracket 160 and to stably engage with the cog formed on the inner surface of the lifting belt 150. [ 11, a protruding rib 161d is formed in the seating groove 161c in a state where a seating groove 161c is formed on the rear surface of the front joining portion 161 so that a point of the lifting belt 150 is seated thereon So that the binding force with the lifting belt 150 is further improved. In the case of such a front coupling part 161, a multi-layer structure having a better area on the rear surface of the base panel 161a and a top panel 161b having the seating groove 161c is formed, A bolt hole or the like for engaging the fastening parts.

In the roller bracket 160, a contact protrusion 161e protruding upwardly and downwardly from the upper end and the lower end of the front surface coupling part 161 is formed. The contact protrusions 161e allow easy contact and switching between the upper contact sensor 181 and the lower contact sensor 182 provided at the upper portion and the lower portion of the casing 110, respectively. As a result, cooperation with the upper contact sensor 181 and the lower contact sensor 182 is performed more smoothly. Therefore, the massage roller 170 can stably control the upper and lower lift ranges.

9 and 11, a fitting hole 161f is formed at an upper end and a lower end of the front surface of the front coupling part 161, respectively, so that a magnet 185 is embedded. When the upper magnet sensor 183 and the lower magnet sensor 184, which detect the magnet, respectively, are installed in the upper and lower parts of the casing 110, the elevating range of the massage roller 170 is controlled more precisely It becomes possible.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is clear that the present invention can be suitably modified and applied in the same manner. Therefore, the above description does not limit the scope of the present invention, which is defined by the limitations of the following claims.
