Abstract
Abstract A plurality of resilient supports or floats are interposed between a body structure such as the box spring of a bed and the bed frame to float the box spring and mattress, and may if desired be used in conjunction with an electrically energizable vibrator clamped to the box spring base to impart vibrations to the entire box spring and mattress when energized. The positioning of the floats and the vibratory characteristics thereof affect the vibrational amplitude and direction which may be generated at different points on the support structure. A resilient rubber column of 30 to 50 durometer is used in each float and provides for movement with three degrees of freedom. Optimum general usage of the suspension system is provided by two floats on each side of the box spring endspaced inward from head and foot , and when used, the vibrator is preferably clamped to one side of the box spring base.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
185 words
A mechanical suspension system for use with a bed having a bed frame, a substantially rigid mattress support having a head end and a foot end and normally carried by the bed frame in direct mechanical engagement, and a mattress carried by the mattress support, said suspension apparatus comprising a plurality of resilient support means each of which is characterized by more than one degree of motional freedom and being each interposable between and mechanically engageable with the mattress support and bed frame and operative when so interposed to resiliently support the mattress support from the bed frame, each of said plurality of resilient support means comprising, a. a base portion including detenting means for mechanically engaging the bed frame, b. an upper anchor element including anchoring means for mechanically engaging the mattress support, and c. a resilient column extending between and secured to each of said base and upper anchor element, said anchoring means of said resilient support means upper anchor element including anti-slip gripping means operative to grip the mattress support and prevent relative lateral movement of said anchor element with respect thereto.
Claim 2
Dependent Claim
185 words
A mechanical suspension system for use with a bed having a bed frame, a substantially rigid mattress support having a head end and a foot end and normally carried by the bed frame in direct mechanical engagement, and a mattress carried by the mattress support, said suspension apparatus comprising a plurality of resilient support means each of which is characterized by more than one degree of motional freedom and being each interposable between and mechanically engageable with the mattress support and bed frame and operative when so interposed to resiliently support the mattress support from the bed frame, each of said plurality of resilient support means comprising, a. a base portion including detenting means for mechanically engaging the bed frame, b. an upper anchor element including anchoring means for mechanically engaging the mattress support, and c. a resilient column extending between and secured to each of said base and upper anchor element, said anchoring means of said resilient support means upper anchor element including anti-slip gripping means operative to grip the mattress support and prevent relative lateral movement of said anchor element with respect thereto.
Claim 3
Dependent Claim
71 words
A suspension system as defined in claim 1 wherein said resilient support means base portion comprises a substantially rigid box having spaced apart top and bottom walls and opposite side walls, said detenting means comprising at least one detenting finger turned out of the said box bottom wall, and said resilient column being secured at its lower end to said box top wall and extending upward to said upper anchor element.
Claim 4
Dependent Claim
70 words
A suspension system as defined in claim 1 wherein said resilient support means base portion comprises a substantially rigid box having spaced apart top and bottom walls and opposite side walls joining said top and bottom walls, said detenting means comprising a removable strip knock-out portion of said sidewalls immediately adjacent to and extending along the edges of said top wall which when removed leave slot openings in said sidewalls.
Claim 5
Dependent Claim
139 words
A suspension system as defined in claim 1 wherein said plurality of resilient support means comprises four such means spaced apart from one another in a generally rectangular array to provide a four point suspension system with the points of suspension lying substantially at the perimeter of and end-spaced inward from the head and foot ends of the mattress support along opposite sides thereof, at least a portion of each said resilient support means having limited two dimensional motional freedom in a substantially horizontal plane and limited motional freedom in a substantially vertical direction, and wherein said resilient column of each said resilient support means is a column of rubber in the range of 30 durometer to 50 durometer of sufficient cross-section and height to maintain resilience and support when subjected to compressional loads up to four hundred pounds.
Claim 6
Dependent Claim
71 words
A suspension system as defined in claim 4 wherein said resilient support means base portion comprises a substantially rigid box having spaced apart top and bottom walls and opposite side walls, said detenting means comprising at least one detenting finger turned out of the said box bottom wall, and said resilient column being secured at its lower end to said box top wall and extending upward to said upper anchor element.
Claim 7
Dependent Claim
34 words
A suspension system as defined in claim 5 wherein said resilient support means are endspaced inward for a distance between ten and fifteen inches from the head and foot ends of the mattress support.
