Abstract
Abstract A device for providing vibrating massage to a user's body that is adaptable to be positioned in several different configurations whereby a user may avail himself of the therapeutic vibration massage and/or heat application features thereof. The device includes an A-frame that is foldable to enable storage and transport of the device while in a compact condition. The A-frame folds out into an open expanded condition to present a cushioned pad having a vibrating unit attached thereto for access by a user. The cushioned pad is held on a rectangular frame that is pivoted to the A-frame to facilitate positioning of the vibrating pad in different angular relationships. A heating unit is included in addition to the vibrating unit to provide heat therapy as well as massage. The A-frame and rectangular frame pivoted thereto enables selective positioning of the pad to facilitate massaging of user's feet, legs, and back.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
129 words
A vibration massage device, comprising: an A-frame comprised of two spaced pairs of upright leg members pivoted at upper ends thereof for movement about a horizontal axis between (a) a storage condition wherein the four legs are in alignment along the horizontal axis with edges thereof being coplanar; and (b) an expanded condition wherein the legs of each pair form an inclusive acute angle about the horizontal axis; a cushioned pad; means for removably mounting the pad to the A-frame; spring means for suspending the cushioned pad on the mounting means and for isolating vibrations of the cushioned pad from the A-frame and mounting means; a vibrating unit on the pad for vibrating the cushioned pad to massage an area of a user's body in contact with the pad.
Claim 2
Dependent Claim
129 words
A vibration massage device, comprising: an A-frame comprised of two spaced pairs of upright leg members pivoted at upper ends thereof for movement about a horizontal axis between (a) a storage condition wherein the four legs are in alignment along the horizontal axis with edges thereof being coplanar; and (b) an expanded condition wherein the legs of each pair form an inclusive acute angle about the horizontal axis; a cushioned pad; means for removably mounting the pad to the A-frame; spring means for suspending the cushioned pad on the mounting means and for isolating vibrations of the cushioned pad from the A-frame and mounting means; a vibrating unit on the pad for vibrating the cushioned pad to massage an area of a user's body in contact with the pad.
Claim 3
Dependent Claim
52 words
The device defined by claim 1 wherein the mounting means comprises: an open rectangular frame pivoted at one side thereof to the A-frame at the horizontal pivot axis thereof; and a leg brace member pivotably mounted at one leg end to the rectangular frame at a side thereof opposite said one side.
Claim 4
Dependent Claim
40 words
The device defined by claim 2 wherein the rectangular frame and leg brace member are foldable with the A-frame to the folded condition, wherein the rectangular frame and leg brace align with the folded A-frame legs along the horizontal axis.
Claim 5
Dependent Claim
32 words
The device defined by claim 2 further comprising release means interconnecting the A-frame and rectangular frame along the horizontal axis for selectively releasing the rectangular frame from pivotal engagement with the A-frame.
Claim 6
Dependent Claim
15 words
The device defined by claim 1 further including a heating unit on the cushioned pad.
Claim 7
Dependent Claim
45 words
The device defined by claim 2 further comprising a cross brace extending between opposed aligned leg members of the A-frame to prevent pivotal movement of the rectangular frame past an aligned condition with the opposed leg members in a direction toward the remaining leg members.
Claim 8
Dependent Claim
25 words
The device defined by claim 6 wherein the leg brace member is of sufficient length to effectively brace the rectangular frame in a horizontal condition.
Claim 9
Dependent Claim
37 words
The device defined by claim 2 wherein the spring means is comprised of a plurality of coil springs each having one end mounted rigidly to the cushioned pad and a remaining end affixed to the rectangular frame.
Claim 10
Dependent Claim
37 words
The device defined by claim 7 wherein the spring means is comprised of a plurality of coil springs each having one end mounted rigidly to the cushioned pad and a remaining end affixed to the rectangular frame.
Claim 11
Dependent Claim
15 words
The device defined by claim 9 further including a heating unit on the cushioned pad.
Claim 12
Dependent Claim
22 words
The device defined by claim 10 further comprising control means for enabling selective control of the vibration frequency of the vibrating unit.
Claim 13
Dependent Claim
62 words
The device as defined by claim 6 wherein the cushioned pad is spaced along the rectangular frame from the horizontal axis, such that when the A-frame is folded to the expanded condition and the rectangular frame is in alignment with the opposed leg members of the A-frame, the pad is elevationally positioned adjacent a support surface to engage a user's lower back.
