`[ 0001 ] The invention relates to percussive massage
`devices and more particularly to a percussive massage
`device having a Universal Serial Bus ( USB ) port .
`2. Description of Related Art
`[ 0002 ] Massage is the manipulation of the body's soft
`tissues . Massage techniques are commonly applied with
`hands , fingers , or other body parts . The purpose of massage
`is generally for the treatment of body stress or pain . There
`are a wide variety of massage devices commercially avail
`able because conventional massage techniques are labori
`ous .
`[ 0003 ] However , conventional massage devices provide
`ineffective massages that are superficial and do not provide
`any real benefit . Further , conventional massage devices have
`only one function of massaging . Furthermore , conventional
`massage devices make a lot of noise in operation due to
`vibration of the electric motor and in turn components
`thereof may loosen after a period of time of use . In addition ,
`conventional massage devices are relatively large .

`further comprising a hollow cylinder secured onto a right
`side of the follower and disposed at right sides of both the
`upper half housing and the lower half housing ; further
`comprising a rubber pad disposed at a right end of the
`hollow cylinder ; further comprising an applicator head
`
`threadedly fastened in the right side of the hollow cylinder ;
`wherein the handle is extended downward from a bottom of
`the lower half housing ; further comprising a plurality of
`eighth screws driven through the lower half housing into the

`
`DETAILED DESCRIPTION OF THE
`INVENTION
`Referring to FIGS . 1 to 3 , a percussive massage
`[ 0017 ]
`device in accordance with the invention comprises an upper
`half housing 1 , an electric motor 2 , a lower half housing 25 ,
`and a handle 30. The motor 2 is provided in the upper half
`housing 1. A plurality of screws 5 are driven through a flange
`4 into a bottom of the motor 2. A plurality of screws 7 are
`driven through the flange 4 into the upper half housing 1. A
`screw 9 is driven through a counterweight 8 into the motor
`2. An eccentric member ( not shown ) is integrally formed
`with the counterweight 8 to make the counterweight 8
`function as an eccentric wheel . The counterweight 8 is
`below the flange 4. A plurality of screws 18 are driven
`through a link 14 into the counterweight 8. A first bearing 17
`is provided in a hole ( not shown ) at a left side of the link 14 .
`A screw 5 is driven through the first bearing 17 into the
`counterweight 8. A screw 20 is used to fasten the first
`bearing 17. A second bearing 15 is provided in a hole ( not
`shown ) at a right side of the link 14. A follower 10 is
`connected to the right side of the link 14. A screw 16 is
`driven through the second bearing 15 into a left side of the
`follower 10 and the link 14. Thus , the follower 10 and the
`link 14 are joined . A plurality of screws 26 are driven
`through the lower half housing 25 into the upper half
`housing 1 to fasten them together . A plurality of rubber
`sleeves 27 each are put on the screw 26. A hollow cylinder
`11 is put on a right side of the follower 10 so that the
`follower 10 and the hollow cylinder 11 may move as a
`whole . The hollow cylinder 10 is disposed at right sides of
`the upper half housing 1 and the lower half housing 25. A
`rubber pad 12 is provided at a right end of the hollow
`cylinder 11. An applicator head 13 is threadedly fastened in
`the right side of the hollow cylinder 11. The handle 30 is
`extended downward from a bottom of the lower half housing
`25. A plurality of screws 24 are driven through the lower half
`housing 25 into the handle 30 to fasten them together . A
`rechargeable battery 32 is provided in the handle 30. A
`Universal Serial Bus ( USB ) printed circuit board ( PCB ) 33
`is provided below the battery 32 at a lower portion of the
`handle 30. A USB port 31 is provided at the lower portion
`of a left side of the handle 30 and connected to the USB PCB
`33 by wire . A USB plug can be inserted into the USB port
`31 to charge , for example a mobile phone . An ammeter 34
`is provided under the USB PCB 33 for measuring the current
`in the battery 32 and showing same . A master PCB 35 is
`provided under the ammeter 34. A rotating shaft 36 is
`provided in the lower portion of the handle 30. A base 37 is
`provided in the lower portion of the handle 30. A plurality
`of screws 38 are driven through the base 37 into the handle
`30 to fasten them together . A screw 41 is driven through a
`washer 40 and an on / off switch 39 into the base 37 to fasten
`them together . The on / off switch 39 can be turned to an off
`position to stop supplying electricity to the USB port 31 ( i.e. ,
`the mobile phone being not charged ) and the motor 2 ( i.e. ,
`being deactivated ) . A rubber cap 28 is mounted on the screw
`41. A DC rubber bar 29 is mounted on a bottom of the base
`37. A speed controller 21 and a speed display 22 for showing
`a rotational speed of the motor 2 are provided at left sides of
`the upper half housing 1 and the lower half housing 25. A
`motor switch 23 is provided on the left side of the upper half
`housing 1 for controlling the on and the off of the motor 2 .
`The motor 2 , the USB PCB 33 , the ammeter 34 , the master
`
`PCB 35 , the speed controller 21 , and the speed display 22
`are electrically connected to the battery 32 .
`[ 0018 ] Four shock absorbing posts 3 are provided at four
`corners of the rectangular flange 4 for absorbing and damp
`ing shock impulses generated by the motor 2. Thus , com
`ponents of the percussive massage device are prevented
`from being loosened . The shock absorbing posts 3 are made
`of rubber and are excellent in absorbing shock .
`[ 0019 ] The screw 7 is driven through each of a plurality of
`washers 6 and a washer 19 is put on the screw 20. The
`battery 32 is a 24 - volt battery . The shock absorbing posts 3
`are provided at four corners of the rectangular flange 4
`respectively for absorbing and damping shock impulses
`generated by the motor 2. Thus , components of the percus
`sive massage device are prevented from being loosened . The
`shock absorbing posts 3 are made of rubber and are excellent
`in absorbing shock .
`[ 0020 ] The screw 7 is driven through each of a plurality of
`washers 6 and a washer 19 is put on the screw 20. The
`battery 32 is a 24 - volt battery . The link 14 is step - shaped and
`has a lower left side and a higher right side . The link 14 is
`used to accommodate a distance between the motor 2 and the
`follower 10 so that the percussive massage device can be
`made compact .
`[ 0021 ]
`Operation of the percussive massage device is
`described below . In response to activating the motor 2 , the
`counterweight 8 rotates . And in turn , the link 14 converts the
`rotational motion of the counterweight 8 into a reciprocating
`linear motion of the follower 10. The application head 13
`thus strongly moves back and forth to treat body stress or
`pain of a user .
`[ 0022 ] The invention has the following advantageous
`effects in comparison with the prior art : a user may charge
`a consumed battery of a mobile phone by inserting a USB
`plug of the mobile phone into the USB port 31. The
`provision of the shock absorbing posts 3 can absorb and
`damp shock impulses generated by the motor 2. Thus ,
`components of the percussive massage device are prevented
`from being loosened . The link 14 is step - shaped and has a
`lower left side and a higher right side . The link 14 is used to
`accommodate a distance between the motor 2 and the
`follower 10 so that the percussive massage device can be
`made compact .
`[ 0023 ] While the invention has been described in terms of
`preferred embodiments , those skilled in the art will recog
`nize that the invention can be practiced with modifications
`within the spirit and scope of the appended claims .
