Abstract

There is provided a leg massager that massages a user's leg by a position-adjustable massaging system for selectively massaging massage target areas of the leg. The leg massager includes: a lower massaging system that massages a massage target area of the user's leg L including at least user's foot F; an upper massaging system that massages an upper massage target area located above the massage target area which is massaged by the lower massaging system; a driving mechanism that drives the upper massaging system and the lower massaging system; and a rockably supporting portion that supports the upper massaging system for rocking motion about its horizontal axis.

Claims (26)

1. A leg massager comprising:

a lower massaging system that massages a massage target area of user's leg including at least user's foot;

an upper massaging system that massages an upper massage target area located above the massage target area which is massaged by the lower massaging system;

a driving mechanism that drives the upper massaging system and the lower massaging system; and

a rockably supporting portion that supports the upper massaging system for rocking motion about a horizontal axis,

wherein the upper massaging system is mounted within an elongated upper casing, and the lower massaging system is mounted within a lower casing,

wherein the rockably supporting portion, which is located toward a top of the lower casing, supports a base end of the upper casing for free rocking motion to impart rising movement to a front end of the upper casing via a horizontally oriented rock shaft,

wherein the upper massaging system has a first massaging member in elongated plate form that performs massage operation for the massage target area, and

wherein, when the upper casing is tilted forwardly to adjacent the lower casing, then the first massaging member housed within the upper casing faces frontward, and, when the upper casing is raised away from the lower casing, then the first massaging member housed within the upper casing faces upward.

2. The leg massager according to claim 1 ,

wherein the driving mechanism drives the upper massaging system and the lower massaging system together.

3. The leg massager according to claim 2 ,

wherein the driving mechanism comprises: a driving motor that produces output of a rotatably driving force; an upper transmission shaft that inputs the rotatably driving force outputted from the driving motor to the upper massaging system; and a lower transmission shaft that inputs the rotatably driving force to the lower massaging system,

and wherein the upper massaging system is driven under the rotatably driving force transmitted thereto through the upper transmission shaft, and the lower massaging system is driven under the rotatably driving force transmitted thereto through the lower transmission shaft.

4. The leg massager according to claim 3 ,

wherein the upper massaging system comprises: a horizontally oriented first rotation shaft which rotates under a rotatably driving force from the upper transmission shaft; a pair of right-hand and left-hand first massaging members located at an intermediate part of the first rotation shaft, the paired first massaging members being movable close to and away from each other under a rotatably driving force exerted by the first rotation shaft for squeezably holding the upper massage target area; and a first conversion section that converts the rotatably driving force of the first rotation shaft into mutually approaching and separating movement of the paired right-hand and left-hand first massaging members.

5. The leg massager according to claim 3 ,

wherein the lower massaging system comprises: a horizontally oriented second rotation shaft which rotates under a rotatably driving force from the lower transmission shaft; a pair of right-hand and left-hand second massaging members located at an intermediate part of the second rotation shaft, the paired second massaging members being movable close to and away from each other under a rotatably driving force exerted by the second rotation shaft for squeezably holding the massage target area including at least the foot; and a second conversion section that converts the rotatably driving force of the second rotation shaft into rocking motion of the paired right-hand and left-hand second massaging members.

6. The leg massager according to claim 4 ,

wherein the rock shaft and the first rotation shaft are implemented by using one common shaft member.

7. The leg massager according to claim 1 ,

wherein the upper massaging system has a pitch adjustment mechanism capable of changing a distance between the paired first massaging members by moving at least one of the paired first massaging members in a horizontal direction.

8. The leg massager according to claim 5 ,

wherein the lower massaging system has a pitch adjustment mechanism capable of changing a distance between the paired second massaging members by moving at least one of the paired second massaging members in a horizontal direction.

9. The leg massager according to claim 1 ,

wherein the driving mechanism drives the upper massaging system and the lower massaging system together.
