Referring to FIG.

As shown in the figure, the calf unit 100 includes a support panel 110, a first motor 120a and a second motor 120b, a roller module 130, a screw (not shown) 140, a first sole massage roller 170 and a second sole massage roller 180.

The support panel 110 supports the main components inside the calf part 100 and includes a first motor 120a and a second motor 120b, a first planting massage roller 170, A lower panel 111 on which the foot massage roller 180 is mounted and supported and a lower panel 111 on which the roller module 130 and the guide member 150 are installed and supported, As shown in FIG.

The first motor 120a is installed in the lower panel 111 inside the casing 190 and serves to provide a driving force to move the roller module 130 up and down through the screw 140, The first foot massager roller 170 and the second foot massager roller 180 serve to provide a driving force to rotate the first foot massager roller 170 and the second foot massager roller 180. [

The screw 140 transmits the driving force of the first motor 120a to the roller module 130. [ For this purpose, the screw 140 is connected to the first motor 120a by a connecting member 121. The connecting member 121 includes a first driving gear 121a coupled to the shaft of the first motor 120a and a first driven gear 121c coupled to the lower end of the screw 140, A first belt 121b for connecting the first driving gear 121a and the first driven gear 121c and a bracket 121d for covering the first belt 121b and the first driven gear 121c.

The roller module 130 is screwed to the screw 140 and moves up and down along the longitudinal direction of the screw 140 to press and massage the user's calf muscles. To this end, the roller module 130 includes an elevation member 131, a calf massage roller 132, a filter member 133, and a advancing / retreating member 134.

The elevating member 131 of the fixed roller module 130 is screwed in a state of passing through the screw 140 and is formed long in the left and right direction. A guide hole 131b is formed in a left side portion and a right side portion of the lifting member 131 in a forward and backward direction to provide a space for accommodating the advancing / retreating member 134 so that the advancing / retreating member 134 can move forward and backward. 3, since the vertical ribs and the vertical ribs intersect with each other to form a skeleton frame structure, it is possible to secure the required strength while reducing the weight of the lifting member 131 itself.

The calf massage roller 132 of the roller module 130 is rotatably installed on the left side and the right side front face of the lifting member 131 so that the user can calmly contact the calf as the lifting member 131 moves up and down. .

A rolling wheel 134a is installed on the advancing / retreating member 134 so as to rotate rearward through a through hole to make a rolling contact with the inclined surface 161 of the inclined member 160. The advancing / retreating member 134 is pushed forward by the inclining member 160 when the lifting member 131 descends along the screw 140, and retreats backward when lifted. As a result, the calf massage roller 132 can be uniformly pressed while advancing or retracting in correspondence to the calf curve formed to be thinner toward the lower side.

3, the pair of inclined members 160 paired with the advancing / retreating member 134 of the roller module 130 are disposed on the left side and the rear side of the right side portion of the elevation member 131 And is provided on the panel 112 so as to support the advancing / retreating member 134 from the rear, and has a front and rear width that becomes thicker as it goes down. As a result, the advancement / retraction member 134 and the calf massage roller 132 are pushed forward as they are lowered, and are guided to be pressed corresponding to the calf bending. As such, the inclined member 160 cooperates with the advancing / retracting member 134 to form a system in which uniform intensity massage can be performed over the entire calf flexibly corresponding to the user's calf bending.

The filter member 133 of the roller module 130 is fitted in a seating groove formed on an upper portion of a center point of the screw 140 in the elevating member 131. The screw 140 is in close contact with the inner circumferential surface And has a through hole 133a penetrating in a state of being formed. The filter member 133 is made of urethane or silicone sponge so as to remove foreign substances on the surface of the screw 140 while moving up and down with the lifting member 131 when the lifting member 131 is lifted or lowered. This eliminates the problem that foreign matter interferes between the screw 140 and the elevating member 131, thereby interfering with the elevating operation of the elevating member 131.

The guide member 150 is vertically provided on the left side and the postal side of the rear panel 112 so as to guide the left and right ends of the elevation member 131 up and down, So that the screw 140 is prevented from being excessively loaded due to unnecessary displacement of the screw 140. The guide member 150 includes a fixing portion 151 fixed to the rear panel 112 and a first extension portion 151 extending forward from the fixing portion 151 and covering a side end portion of the elevation member 131, A second extending portion 153 extending from the front end of the first extending portion 152 to the front end of the side end portion of the elevating member 131 and covering the entire side end of the elevating member 131, As shown in Fig. A plurality of ribs 154 are formed on the outer side of the cover at regular intervals along the vertical direction to reinforce the strength. The cover of the guide member 150 is configured such that the left end portion and the right end portion of the elevating member 131 are moved in the front and left and right directions by the first extending portion 152 and the second extending portion 153, It is restrained from being displaced by more than a certain amount.

The guide member 150 further includes a pair of guide protrusions 155 extending vertically from the rear panel 112 at the left and rear ends of the elevation member 131. The left and right rear ends of the elevating member 131 are guided along the guide protrusions 155 so as to prevent the elevating member 131 from being displaced to the left and right by a predetermined amount or more. And a guide portion 131d having a cross section is further formed. The guide member 150 can control the displacement of the elevating member 131 in the forward, backward, and leftward and rightward directions, so that the excessive load on the first motor 120a due to the unbalanced inclination of the elevating member 131, And the elevating member 131 can move up and down more smoothly.
