Abstract
Abstract The apparatus comprises a base having bed support structure pivotally coupled thereto for rocking motion about an upper axis. The bed support structure includes a first guide fixedly connected thereto for rocking motion with the bed support structure. A second guide is pivotally connected to the base for rocking motion about a lower axis. A drive, crank, and linkage are employed for rocking the second guide. Coupling means couples the two guides together such that the first guide and hence the bed support structure is rocked about its axis as the second guide is rocked about its axis. Adjusting means adjusts the position of the coupling means relative to the two guides to adjust the angle through which the support structure may be rocked.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
193 words
An apparatus for supporting and rocking a bed or the like, comprising: base means, support means having structure for supporting a bed, said support means being pivotally coupled to said base means for rocking motion about a first axis, crank means, drive means coupled to said crank means for rotating said crank means, guide means pivotally coupled to said base means for rocking motion about a second axis spaced from said first axis, arm means having a first end pivotally coupled to said crank means, said arm means having a second end pivotally coupled to said guide means for rocking said guide means about said second axis as said crank means is rotated by said drive means, coupling means having a first portion coupled to said guide means and a second portion coupled to said support means for rocking said support means about said first axis as said guide means is rocked about said second axis, and adjusting means for adjusting the position of said coupling means relative to said support means and to said guide means to adjust the angle through which said support means may be rocked about said first axis.
Claim 2
Independent Claim
193 words
An apparatus for supporting and rocking a bed or the like, comprising: base means, support means having structure for supporting a bed, said support means being pivotally coupled to said base means for rocking motion about a first axis, crank means, drive means coupled to said crank means for rotating said crank means, guide means pivotally coupled to said base means for rocking motion about a second axis spaced from said first axis, arm means having a first end pivotally coupled to said crank means, said arm means having a second end pivotally coupled to said guide means for rocking said guide means about said second axis as said crank means is rotated by said drive means, coupling means having a first portion coupled to said guide means and a second portion coupled to said support means for rocking said support means about said first axis as said guide means is rocked about said second axis, and adjusting means for adjusting the position of said coupling means relative to said support means and to said guide means to adjust the angle through which said support means may be rocked about said first axis.
Claim 3
Dependent Claim
127 words
The apparatus of claim 1, wherein: said base means comprises: first and second spaced apart end means, first longitudinal connecting means connecting together said first and second end means at spaced apart positions, and first and second vertical support means extending upward from said first and second end means respectively, said first and second vertical support means being located in alignment with each other for defining said first axis, said support means comprises: first and second arm means pivotally coupled to said first and second vertical support means respectively for rocking motion about said first axis, second longitudinal connecting means connecting together said first and second arm means at spaced apart positions, said first and second arm means comprising structure for supporting opposite ends of a bed.
Claim 4
Dependent Claim
35 words
The apparatus of claim 2 wherein: said first and second longitudinal connecting means and said first and second arm means are adjustable in length to allow said support means to support beds of different sizes.
Claim 5
Dependent Claim
86 words
The apparatus of claim 1 comprising: first pivot means coinciding with said first axis and coupled to said base means and to said support means for allowing said support means to pivot in a rocking motion about said first axis, and second pivot means coinciding with said second axis and coupled to said base means and to said guide means for allowing said guide means to pivot in a rocking motion about said second axis, said second pivot axis being located below said first pivot axis.
Claim 6
Dependent Claim
157 words
The apparatus of claim 4 wherein: said support means comprises guide means fixedly connected to said support means for rocking motion therewith, said guide means supported for rocking motion about said second axis having guiding surface means extending below said second pivot axis for engagement with said first portion of said coupling means, said guide means fixedly connected to said support means having guided surface means extending below said first pivot axis and to a lower position below said second pivot axis for engagement with said second portion of said coupling means, said adjusting means being adapted to adjust the position of said coupling means to locate its second portion to different positions along said guiding surface means of said guide means fixedly connected to said support means thereby locating said first portion of said coupling means to different positions along said guiding surface means to said guide means supported for rocking motion about said second axis.
Claim 7
Dependent Claim
52 words
The apparatus of claim 5 wherein: said first portion of said coupling means may be moved along said guiding surface means of said guide means supported for rocking motion about said second axis between an upper position at or near said second axis to a lower position spaced from said second axis.
Claim 8
Dependent Claim
33 words
The apparatus of claim 5 wherein: said guide means fixedly connected to said support means is located at a position outward of said guide means supported for rocking motion about said second axis.
