  • the locking mechanism 180 includes a bolt member 183 having a body portion 183c, and a peg 183a and at least one cylindrical column 183b respectively protruded from the body portion 183c, positioned over the cushion member 182 such that the peg 183a and the at least one cylindrical column 183b are respectively corresponding to the first opening 182a and the at least one second opening 182b of the cushion member 182.
  • the locking mechanism 180 includes a wedge member 184 including a base portion 184a and a side portion 184b extending at an angle from the base portion 184a, positioned such that the base portion 184a is under the cushion member 182 and operably engaged with the bolt member 183.
  • the locking mechanism 180 includes an eccentric block 185 having a protrusion 185a, engaged with the at least one first motor 141 such that the protrusion 185a is operably against to the side portion 184b of the wedge member 184.
  • the locking mechanism 180 may also include an ejector positioned under the peg 183a of the bolt member 183.
  • the wedge member 184 is formed in an L-like shape.
  • the locking mechanism 180 is pre-set such that the at least one tab 131b of the chassis member 131 is received in the at least one step-like recess 181a of the base member 181; the peg 183a of the of the bolt member 183 is snapped, through the first opening 182a of the cushion member 182, into the bore 181b of the base member 181; the at least one cylindrical column 183b of the bolt member 183 is snapped, through the at least one second opening 182b of the cushion member 182 and the hole 131 c of the at least one tab 131b of the chassis member 131, into the at least one step-like recess 181a of the base member 181; and the base portion 184a of the wedge member 184 is positioned under the cushion member 182 and releasably engaged with the bolt member 183, thereby locking the chassis member 131 from moving.
  • the eccentric block 185 rotates around the output shaft 141a of the first motor 141, and the rotation of the eccentric block 185 causes the protrusion 185a to push the side portion 184b of the wedge member 184 to move towards a position limit point of the cushion member 182 so as to eject the bolt member 183, thereby releasing the at least one tab 131b of the chassis member 131 from the base member 181 of the locking mechanism 180.
  • the massage device 100 may further comprise a remote controller 190 and a circuit board 195 which is coupled to the first moter141 and the second motor 171 and adopted for receiving wireless signals emitted from the remote controller 190.
  • a user is capable of activating the at least one the first motor 141 and the second motor 171 using the remote controller 190.
  • the output shaft 171a of the second motor 171 may be controlled to rotate either clockwise or counter-clockwise so as to move carriage 130 along the guiding rails 112 and then stop the carriage 130 at a pre-determined position of the guiding rails 112.
  • multiple sensors coupled the circuit board 195 may be arranged along a path parallel to the guiding rail 112 so as to divide the guiding rail 112 into several sections. Under this arrangement, a user is capable of using the remote controller 195 to activate the second motor 171 for moving the carriage 130 back and forth along the guiding rail 112 inside the selected section.
  • the present invention recites a massage device that utilizes a locking mechanism to releasably lock the massage assemblies from moving.
  • the present invention relates to a locking mechanism and a massage device of using same.
  • the locking mechanism includes a base member secured to the a base cover of the massage device, a cushion member positioned over the base member, a bolt member positioned over the cushion member, a wedge member operably engaged with the bolt member, and an eccentric block engaged with the wedge member and a motor of the massage device.
  • the locking mechanism is configured such that the carriage of the massage device is pre-locked against movements, and the activation of the motor unlocks the massage device.
