Primary Examiner:
Trapp L. W.
Claims:
I claim

1. In a contour and cushion vibrator the combination of a cushion comprised of a pair of cushion members pivotally connected together by hinges, said members having upon their upper side a contour which in combination comprises a contour of a person's body reclined thereupon, and said cushion having self-contained means so to massage a person's body while so reclined.

2. The combination as set forth in claim 1 wherein said means comprises a horizontal opening in a side of said cushion, a removable case in said opening, said case containing a motor, dry cell batteries and switch in electric circuit, said case having a removable end cap having an end wall flush with said side of said cushion, said end cap end wall having a projecting switch button, and said motor driving a crank on a motor shaft thereof, said crank driving a weight reciprocally vertically slidable between stationary parts.

3. The combination as set forth in claim 2 wherein said weight has a central chamber containing a quantity of liquid mercury for providing extra hammering force on the upper and lower end walls of said chamber.

Description:
This invention relates generally to vibrating massagers, and is an improvement over applicant's earlier patent application on a contoured cushion.

A principal object of the present invention is to provide a vibrator fitted into a contoured cushion.

Another object is to provide a vibrator cushion that is contoured to an individual reclined thereupon.

Another purpose is to provide a vibrator cushion which is foldable so to be conveniently stored away or which can be easily transported in a minimum size.

Yet another purpose is to provide a vibrator cushion wherein there is a principally vertical movement in the vibrating movement of the cushion so to give an up and downward massage to a body reclined thereupon.

Other objects are to provide a vibrator cushion which is simple in design, inexpensive to manufacture, rugged in construction, easy to use and efficient in operation.

These and other objects will be readily evident upon a study of the following specification and the accompanying drawing wherein:

FIG. 1 is a perspective view of the invention.

FIG. 2 is a cross section on line 2--2 of FIG. 1.

FIG. 3 is a cross section on line 3--3 of FIG. 1.

FIG. 4 is a cross section on line 4--4 of FIG. 3.

FIG. 5 is a perspective view of the vertically vibrating mechanism.

FIG. 6 is a modified design taken on line 6--6 of FIG. 5 showing wherein the weight is hollow and contains a quantity of mercury which gives an extra hammer blow at upper and lower extremes for further vibration.

Referring now to the drawing in detail the reference numeral 10 represents a vibrator cushion according to the present invention wherein there is a cushion member 11 comprised of two parts 12 and 13 which are pivotally connected together by hinges 14 so that the parts can be folded over into a small unit for easy transportation or storage. The parts are each provided with a contour 15 on their upper side so to conform to the shape of a person's body reclining thereupon.

In this invention, the member 12 includes a vibrator mechanism 16 for massaging particularly the muscles of the person. The member 16 has a horizontal opening 17 therein into which there is inserted a case 18 having an end cap 19 on the end thereof, the end wall 20 of the cap being aligned with a sidewall 21 of the member 12 so that a switch button 22 projecting from the end wall 20 can be conveniently manually operated while a person is reclining on the cushion.

Within the case 18, there is located a plurality of dry cell batteries 23 in electrical circuit with a switch 24 and a motor 25 that drives an eccentric mechanism 26.

The mechanism 26 comprises a weight 27 vertically slidable along vertical posts 28 stationarily mounted in the case. A horizontal slot 29 in the weight receives a pin 30 on the end of a crank arm 31 rotatable about a motor shaft 32 of the motor 25.

In operative use, a person reclines on the cushion, flips the button and receives a massage wherein there is principally a vertical movement so to massage his muscles.

In FIG. 6 a modified construction of weight 33 is shown comprising a hollow chamber 34 therewithin containing a quantity of mercury 35 so that upon vertical travel of the weight there is an extra thrust force on each end stroke of the weight due to a tardy lag of the fluid mercury hitting the upper or lower end wall of the chamber.

Thus there is provided an improved contour and cushion vibrator for promoting good health and relaxation.

While various changes may be made in the detail construction, it is understood that such changes will be within the spirit and scope of the present invention.
