Abstract:
An adjustable incline sleeper includes a lower base frame including lower support members movable between a first rocking position which permits rocking of the adjustable incline sleeper in a transverse direction and a second non-rocking position which prevents rocking of the adjustable incline sleeper; an upper support frame; a covering body secured to the upper support frame for supporting an infant thereon; and a pivotable connection arrangement for connecting the upper support frame to the lower base frame in a manner to permit transverse pivotable movement of the upper support frame relative to the lower base frame to change an inclination angle between the upper support frame and the lower support frame.

Description:
BACKGROUND OF THE INVENTION 
     The present invention relates generally to infant sleepers, and more particularly, is directed to an adjustable incline sleeper. 
     Bassinets are well known substitutes for large cribs, particularly for newborn infants, because of their smaller size. Because of their small size, they are generally well suited for transportation to and storage at different locations. 
     However, in many cases, bassinets also too large and bulky. Recently, Fisher-Price, Inc. has introduced a sleeper, which is formed by a frame which, when opened, has an X-shape with a fabric seat connected between the spaced apart upper ends for supporting an infant thereon. The upper ends of the frame can be inclined so that the fabric seat is also slightly inclined. The lower end supports are slightly curved so that the sleeper can be rocked back and forth gently, either by hand, or by a motor. This sleeper is advertised as being a sleeper in which an infant can nap or even sleep through the night, as well as being a playtime seat. Because of the X-shaped frame, this sleeper can be pivoted to a closed position in which the X-shape is collapsed and folded flat for storage and transportation. 
     However, the inclination of the upper end is at a fixed angle at all times. Further, the inclination angle is very small so that the infant cannot effectively sit up in the sleeper. Therefore, to feed the infant, it is necessary to remove the infant from the sleeper and place the infant in a highchair or the like. 
     SUMMARY OF THE INVENTION 
     Accordingly, it is an object of the present invention to provide an adjustable incline sleeper that overcomes the aforementioned problems. 
     It is another object of the present invention to provide an adjustable incline sleeper in which the inclination angle can be adjusted. 
     It is still another object of the present invention to provide an adjustable incline sleeper which can also rock back and forth. 
     It is yet another object of the present invention to provide an adjustable incline sleeper which can also be prevented from rocking back and forth. 
     It is a further object of the present invention to provide an adjustable incline sleeper that folds flat and compact for storage and transportation. 
     It is a still further object of the present invention to provide an adjustable incline sleeper that is easy and economical to use and manufacture. 
     In accordance with an aspect of the present invention, an adjustable incline sleeper includes a lower base frame including lower support members movable between a first rocking position which permits rocking of the adjustable incline sleeper in a transverse direction and a second non-rocking position which prevents rocking of the adjustable incline sleeper; an upper support frame; a covering body secured to the upper support frame for supporting an infant thereon; and a pivotable connection arrangement for connecting the upper support frame to the lower base frame in a manner to permit transverse pivotable movement of the upper support frame relative to the lower base frame to change an inclination angle between the upper support frame and the lower support frame. 
     Specifically, each lower support member includes a curved tube which is movable between a downwardly convex position in the first rocking position and an upwardly convex position in the second non-rocking position. The curved tube further includes at least one stop extension mounted thereto which is moved into supporting contact with a ground surface to prevent rocking of the adjustable incline sleeper when the curved tube is moved to the upwardly convex position in the second non-rocking position. There is also an arrangement for releasably locking the curved tube between the downwardly convex position in the first rocking position and the upwardly convex position in the second non-rocking position. 
     The pivotable connection arrangement includes a pivot connection which pivotally connects together a first side of the upper support frame to the lower base frame; and an adjustment arrangement for adjusting a vertical separation distance of an opposite second side of the upper support frame to the lower base frame. 
     The adjustment arrangement includes a housing mounted to the second side of either the upper support frame or the lower base frame; an adjustment rod having one end mounted to the side of the other of the upper support frame or the lower base frame; the adjustment rod slidably received in the housing; and a releasable locking arrangement for releasably locking the adjustment rod at different positions to the housing so as to adjust the distance of the second side of the upper support frame to the lower base frame. 
     The releasable locking arrangement includes a plurality of spaced apart openings in the adjustment rod, and a pin in the housing which is adapted to selectively enter a selected one of the spaced apart openings. The releasable locking arrangement further includes a slide having the pin secured thereto and which is slidably mounted in a first direction in the housing, the slide including a first wedge surface, a spring member for biasing the slide in a direction for moving the pin into a selected one of the spaced apart openings, and a release member slidably mounted in the housing in a second direction transverse to the first direction, and including a second wedge surface for engaging the first wedge surface to move the slide in a direction against the biasing force of the spring member in order to remove the pin from the selected one of the spaced apart openings. 
     The lower base frame includes a first U-shaped base tube including one lower support member; a second opposite U-shaped base tube including another lower support member; and a first pivoting connection assembly which pivotally connects together the first and second U-shaped base tubes for movement between an inverted V-shape in an operative condition of the adjustable incline sleeper and a collapsed, closed condition in which the first and second U-shaped base tubes are substantially parallel and adjacent to each other. 
     The upper support frame includes a third U-shaped support tube having an upper end to which the covering body is secured; a fourth U-shaped support tube having an upper end to which the covering body is secured; and a second pivoting connection assembly which pivotally connects together the third and fourth U-shaped support tubes for movement between a V-shape in an operative condition of the adjustable incline sleeper and a collapsed, closed condition in which the third and fourth U-shaped support tubes are substantially parallel and adjacent each to other. 
     Specifically, the first pivoting connection assembly includes a lower left side pivot assembly which pivotally connects together a left side of the first and second U-shaped support tubes, and a lower right side pivot assembly which pivotally connects together a right side of the first and second U-shaped support tubes; and the second pivoting connection assembly includes an upper left side pivot assembly which pivotally connects together a left side of the third and fourth U-shaped support tubes, and an upper right side pivot assembly which pivotally connects together a right side of the third and fourth U-shaped support tubes. 
     The pivotable connection arrangement includes a pivot connection which pivotally connects together the lower right side pivot assembly and the upper right side pivot assembly; and an adjustment arrangement connected between the lower left side pivot assembly and the upper left side pivot assembly for adjusting a vertical separation distance of a left side of the upper support frame to the lower base frame. 
     The adjustment arrangement includes a housing mounted to either the lower left side pivot assembly or the upper left side pivot assembly; an adjustment rod having one end mounted to the other of the lower left side pivot assembly and the upper left side pivot assembly; the adjustment rod slidably received in the housing; and a releasable locking arrangement for releasably locking the adjustment rod at different positions to the housing so as to adjust the distance of the upper left side pivot assembly to the lower left side pivot assembly. 
     The releasable locking arrangement includes a plurality of spaced apart openings in the adjustment rod, and a pin in the housing which is adapted to selectively enter a selected one of the spaced apart openings. The releasable locking arrangement further includes a slide having the pin secured thereto and which is slidably mounted in a first direction in the housing, the slide including a first wedge surface, a spring member for biasing the slide in a direction for moving the pin into a selected one of the spaced apart openings, and a release member slidably mounted in the housing in a second direction transverse to the first direction, and including a second wedge surface for engaging the first wedge surface to move the slide in a direction against the biasing force of the spring member in order to remove the pin from the selected one of the spaced apart openings.

     DETAILED DESCRIPTION 
     Referring to the drawings in detail, an adjustable incline sleeper  10  according to the present invention includes an X-shaped frame  12  and a flexible covering body  14  therefor. 
     Frame  12  includes a lower pivotable base frame  16 , an upper pivotable support frame  18 , and a transverse pivotable connection arrangement  24  for connecting upper support frame  18  to lower base frame  16  in a manner to permit transverse pivotable movement at a left side of frame  12  relative to a right side of frame  12 . 
     Specifically, lower pivotable base frame  16  includes a first U-shaped tube assembly  26 , a second U-shaped tube assembly  28  and a pivoting connection assembly  34  connecting together U-shaped tube assemblies  26  and  28  for pivoting movement between an open position where the U-shaped tube assemblies  26  and  28  form an inverted V-shape as shown in  FIG. 2  and a collapsed, closed position where the U-shaped tube assemblies  26  and  28  are parallel and adjacent to each other as shown in  FIG. 14B . 
     First U-shaped tube assembly  26  includes a left tube section  26   a , a spaced apart parallel right tube section  26   b  and a connecting tube section  26   c  which connects together the lower ends of left and right tube sections  26   a  and  26   b . Connecting tube section  26   c  is slightly curved to permit transverse rocking back and forth of frame  12  in the fully open position, that is, from left to right and right to left. 
     In like manner, second U-shaped tube assembly  28  includes a left tube section  28   a , a spaced apart parallel right tube section  28   b  and a connecting tube section  28   c  which connects together the lower ends of left and right tube sections  28   a  and  28   b . Connecting tube section  28   c  is also slightly curved to permit transverse rocking back and forth of frame  12  in the fully open position, that is, from left to right and right to left. 
     Transverse rocking control assemblies  40  rotatably connect opposite ends of connecting tube section  26   c  to the respective lower ends of left and right tube sections  26   a  and  26   b , and other transverse rocking control assemblies  40  rotatably connect opposite ends of connecting tube section  28   c  to the respective lower ends of left and right tube sections  28   a  and  28   b.    
     As shown best in  FIGS. 18-21 , each transverse rocking control assembly  40  includes a rotatable connector  42  having inner and outer coaxial, adjacent cylindrical housings  44  and  46  which are rotatable relative to each other. A connecting tube  48  is connected to and extends radially outward from the outer surface of outer cylindrical housing  46  for receiving the lower end of the respective tube section  26   a ,  26   b ,  28   a ,  28   b  which is fixed thereto by a rivet  50 . A connecting tube  52  is connected to and axially extends inwardly from the inner surface of inner cylindrical housing  44  for receiving one end of connecting tube section  26   c ,  28   c  which is fixed thereto by a rivet  54 . 
     A stop extension  56  is fixed to the outer surface of each connecting tube  52  and extends radially outward therefrom. Because of the rotating nature of inner and outer cylindrical housings  44  and  46  relative to each other, connecting tube sections  26   c ,  28   c  and inner cylindrical housings  44  connected thereto, can be rotated relative to outer cylindrical housings  46  between a first rocking position shown in  FIG. 2  and a second non-rocking position shown in  FIG. 8 . 
     Specifically, in the first rocking position shown in  FIG. 2 , each connecting tube section  26   c ,  28   c  is convexly curved in a downward manner to permit transverse rocking of adjustable incline sleeper  10 . In this position, stop extensions  56  are oriented upwardly away from the floor surface. In the second non-rocking position shown in  FIG. 8 , each connecting tube section  26   c ,  28   c  is convexly curved in an upward manner and stop extensions  56  are oriented downwardly in a manner to support adjustable incline sleeper  10  on the floor surface, thereby preventing transverse rocking. 
     In order to permit rotational movement of each connecting tube section  26   c ,  28   c  between the positions shown in  FIGS. 2 and 8 , and to lock the connecting tube sections  26   c ,  28   c  in their respective positions, each outer cylindrical housing  46  includes an outer circular recess  58  centrally located in the outer axial surface thereof, and the inner surface thereof includes a first locking recess  60  formed by a central circular recess section  62  and diametrically opposite outer recess sections  64  in open communication with circular recess section  62 . Recess sections  64  can have any suitable shape, for example, a substantially rectangular shape or the like. As a result, a central dividing wall  66  separates outer circular recess  58  from first locking recess  60 . 
     Four equiangularly spaced arcuate openings  68  are formed in central dividing wall  66  within the boundaries of central circular recess section  62 . 
     A pushbutton  70  having a circular head  72  with dimensions slightly smaller than the diameter of outer circular recess  58 , is slidably position within outer circular recess  58 . Four equiangularly spaced legs  74  extend at right angles from the inner surface of circular head  72 , with outwardly turned catches  76  at the free ends thereof. Legs  74  fit within openings  68 , and catches  76  prevent escape of legs  74  from openings  68 , while permitting axial sliding movement of legs  74  within openings  68 . 
     A locking member  78  is provided, having a central annular section  80  of the same dimensions as central circular recess section  62 , and diametrically opposite outer sections  82  of the same dimensions as outer recess sections  64 , such that locking member  78  is adapted to be positioned within first locking recess  60 . Locking member  78  also includes an outer closure wall  79  connected to the outer edges of central annular section  80  and outer sections  82 . 
     The outer axial surface of inner annular housing  44  includes a second locking recess  84  formed by a central circular recess section  86  and diametrically opposite outer recess sections  88  in open communication with circular recess section  86 . Circular recess section  86  and outer recess sections  88  have the same shapes and dimensions as circular recess section  62  and outer recess sections  64 . As a result, locking member  78  also fits within second locking recess  84 . 
     A central post  90  extends axially from the inner wall  92  of second locking recess  84 , and specifically, is centrally located within circular recess section  86  thereof. A coil spring  94  is positioned around central post  90  and extends between closure wall  79  and inner wall  92  so as to normally bias locking member  78  into first locking recess  60 . In this position, as shown in  FIGS. 20 and 21 , locking member  78  is also positioned within second locking recess  84 , thereby preventing rotation of inner and outer circular housings  44  and  46  relative to each other. This would correspond to either rotation of the respective connecting tube section  26   c ,  28   c  in the position shown in  FIG. 2  or  FIG. 8 . 
     When it is desired to rotate the respective connecting tube section  26   c ,  28  to the other position, pushbutton  70  is pushed inwardly, whereby free ends of legs  74  thereof push locking member  78  inwardly so that locking member  78  is fully positioned within second locking recess  84  and is completely out of first locking recess  60 , thereby permitting relative rotation between inner and outer annular housings  44  and  46 . Once pushbutton  70  is released, coil spring  94  biases locking member  78  back into engagement with both first locking recess  60  and second locking recess  84  to again prevent rotation of inner and outer circular housings  44  and  46  relative to each other. 
     As shown best in  FIGS. 22-29 , pivoting connection assembly  34  includes a lower right side cylindrical pivot assembly  100  including inner and outer coaxial, adjacent cylindrical housings  102  and  104  which are rotatable relative to each other. A connecting tube  106  is connected to and extends radially down from the outer surface of outer cylindrical housing  104  for receiving the upper end of the tube section  28   b  which is fixed thereto by a rivet  110 . A connecting tube  112  is connected to and extends radially down from the outer surface of inner cylindrical housing  102  for receiving the upper end of the tube section  26   b  which is fixed thereto by a rivet  114 . Because of the rotating nature of inner and outer cylindrical housings  102  and  104  relative to each other, connecting tube sections  26   b  and  28   b  can be pivoted between a first open position shown in  FIG. 2  and a second collapsed position shown in  FIG. 14B . 
     Each cylindrical housing  102  and  104  includes an upper arcuate projection  116  which extends upwardly from the outer surface thereof, for fitting within arcuate slots (as will be described hereafter), to maintain cylindrical housings  102  and  104  in their coaxial, adjacent positions and to limit the pivoting extent thereof between the positions shown in  FIGS. 2 and 14B . 
     In order to permit pivotal movement of tube sections  26   a ,  26   b ,  28   a ,  28   b  between the positions shown in  FIGS. 2  and  14 B, and to lock the tube sections  26   a ,  26   b ,  28   a ,  28   b  in their respective positions, each outer cylindrical housing  104  includes an outer facing circular recess  118  centrally located in the outer facing axial surface thereof, and the inner surface thereof includes a first locking recess  120  formed by a central circular recess section  122  and four equiangularly arranged outer recess sections  124  in open communication with circular recess section  122 . Recess sections  124  can have any suitable shape, for example, a substantially rectangular shape or the like. As a result, a central dividing wall  126  separates outer circular recess  118  from first locking recess  120 . 
     Four equiangularly spaced arcuate openings  128  are formed in central dividing wall  126  within the boundaries of central circular recess section  122 . 
     A pushbutton  130  having a circular head  132  with dimensions slightly smaller than the diameter of outer circular recess  118 , is slidably positioned within inner circular recess  118 . Four equiangularly spaced legs  134  extend at right angles from circular head  132 , with outwardly turned catches  136  at the free ends thereof. Legs  134  fit within openings  128 , and catches  136  prevent escape of legs  134  from openings  128 , while permitting axial sliding movement of legs  134  within openings  128 . 
     A locking member  138  is provided, having a central annular section  140  of the same dimensions as central circular recess section  122 , and diametrically opposite outer sections  142  of the same dimensions as outer recess sections  124 , such that locking member  138  is adapted to be positioned within first locking recess  120 . Locking member  138  also includes an inner closure wall  139  connected to the outer facing edges of central annular section  140  and outer sections  142 . 
     The outer facing axial surface of inner annular housing  102  includes a second locking recess  144  formed by a central circular recess section  146  and diametrically opposite outer recess sections  148  in open communication with circular recess section  146 . Circular recess section  146  and outer recess sections  148  have the same shapes and dimensions as circular recess section  122  and outer recess sections  124 . As a result, locking member  138  also fits within second locking recess  144 . 
     A central post  150  extends axially from the lower wall  152  of second locking recess  144 , and specifically, is centrally located within circular recess section  146  thereof. A coil spring  154  is positioned around central post  150  and extends between closure wall  139  and lower wall  152  so as to normally bias locking member  138  into first locking recess  120 . In this position, locking member  138  is also positioned within second locking recess  144 , thereby preventing rotation of inner and outer circular housings  102  and  104  relative to each other. This would correspond to pivoting of tube sections  26   a ,  26   b ,  28   a ,  28   b  in the position shown in  FIG. 2  or  FIG. 14B . 
     Lastly, a pivot rod  141  ( FIG. 27 ) is axially positioned centrally within axial openings in cylindrical housings  102  and  104  about which cylindrical housings  102  and  104  rotate relative to each other, and which further maintain cylindrical housings  102  and  104  in their axial rotatable positions relative to each other. 
     When it is desired to rotate the respective tube sections  26   a ,  26   b ,  28   a ,  28   b  to the other position, pushbutton  130  is pushed inwardly, whereby free ends of legs  134  thereof push locking member  138  inwardly so that locking member  138  is fully positioned within second locking recess  144  and is completely out of first locking recess  120 , thereby permitting relative rotation between inner and outer annular housings  102  and  104 . Once pushbutton  130  is released, coil spring  154  biases locking member  138  back into engagement with both first locking recess  120  and second locking recess  144  to again prevent rotation of inner and outer circular housings  102  and  104  relative to each other. 
     As shown best in  FIGS. 2 and 30 , pivoting connection assembly  34  further includes a lower left side cylindrical pivot assembly  200  including inner and outer coaxial, adjacent cylindrical housings  202  and  204  which are rotatable relative to each other. A connecting tube  206  is connected to and extends radially down from the outer surface of outer cylindrical housing  204  for receiving the upper end of the tube section  28   a  which is fixed thereto by a rivet  210 . A connecting tube  212  is connected to and extends radially down from the outer surface of inner cylindrical housing  202  for receiving the upper end of the tube section  26   a  which is fixed thereto by a rivet  214 . Because of the rotating nature of inner and outer cylindrical housings  202  and  204  relative to each other, connecting tube sections  26   a  and  28   a  can be pivoted between a first open position shown in  FIG. 2  and a second collapsed position shown in  FIG. 14B . 
     Each cylindrical housing  202  and  204  includes an upper arcuate projection  216  which extends upwardly from the outer surface thereof, for fitting within arcuate slots (as will be described hereafter), to maintain cylindrical housings  202  and  204  in their coaxial, adjacent positions and to limit the pivoting extent thereof between the positions shown in  FIGS. 2 and 14B . 
     Lastly, a pivot rod  241  is axially positioned centrally within axial openings in cylindrical housings  202  and  204  about which cylindrical housings  202  and  204  rotate relative to each other, and which further maintain cylindrical housings  202  and  204  in their axial rotatable positions relative to each other. 
     It will be appreciated that the locking mechanism of lower right side cylindrical pivot assembly  100  is not required with lower left side cylindrical pivot assembly  200 , since the locking mechanism only need be provided on one side of frame  12 . 
     Upper pivotable base frame  18  includes a first U-shaped tube assembly  256 , a second U-shaped tube assembly  258  and a pivoting connection assembly  254  connecting together U-shaped tube assemblies  256  and  258  for pivoting movement between an open position where the U-shaped tube assemblies  256  and  258  form a V-shape as shown in  FIG. 2  and a collapsed, closed position where the U-shaped tube assemblies  256  and  258  are parallel and adjacent to each other as shown in  FIG. 14B . 
     First U-shaped tube assembly  256  includes a left tube section  256   a , a spaced apart parallel right tube section  256   b  and a connecting tube section  256   c  which connects together the upper ends of left and right tube sections  256   a  and  256   b . In like manner, second U-shaped tube assembly  258  includes a left tube section  258   a , a spaced apart parallel right tube section  258   b  and a connecting tube section  258   c  which connects together the upper ends of left and right tube sections  258   a  and  258   b.    
     Flexible covering body  14  has opposite ends connected to connecting tube sections  256   c  and  258   c  by any conventional means, such as stitching, snaps, Velcro or the like. 
     Pivoting connection assembly  254  includes an upper right side cylindrical pivot assembly  300  including inner and outer coaxial, adjacent cylindrical housings  302  and  304  which are rotatable relative to each other. A connecting tube  306  is connected to and extends radially up from the outer surface of outer cylindrical housing  304  for receiving the upper end of the tube section  258   b  which is fixed thereto by a rivet  310 . A connecting tube  312  is connected to and extends radially up from the outer surface of inner cylindrical housing  302  for receiving the upper end of the tube section  256   b  which is fixed thereto by a rivet  314 . Because of the rotating nature of inner and outer cylindrical housings  302  and  304  relative to each other, connecting tube sections  256   b  and  258   b  can be pivoted between a first open position shown in  FIG. 2  and a second collapsed position shown in  FIG. 14B . 
     Each cylindrical housing  302  and  304  includes a lower arcuate projection  316  ( FIG. 27 ) which extends downwardly from the outer surface thereof, for fitting within arcuate slots (as will be described hereafter), to maintain cylindrical housings  302  and  304  in their coaxial, adjacent positions and to limit the pivoting extent thereof between the positions shown in  FIGS. 2 and 14B . 
     Right side cylindrical pivot assembly  300  is constructed in an identical manner, and operates in the same manner as right side cylindrical pivot assembly  100  so that a detailed description thereof is omitted, except that right side cylindrical pivot assembly  300  is inverted 180 degrees from right side cylindrical pivot assembly  100 . 
     Pivoting connection assembly  254  further includes an upper left side cylindrical pivot assembly  400  including inner and outer coaxial, adjacent cylindrical housings  402  and  404  ( FIG. 17 ) which are rotatable relative to each other. A connecting tube  406  is connected to and extends radially up from the outer surface of outer cylindrical housing  404  for receiving the upper end of the tube section  258   a  which is fixed thereto by a rivet  410 . A connecting tube  412  is connected to and extends radially up from the outer surface of inner cylindrical housing  402  for receiving the upper end of the tube section  256   a  which is fixed thereto by a rivet  414 . Because of the rotating nature of inner and outer cylindrical housings  402  and  404  relative to each other, connecting tube sections  256   a  and  258   a  can be pivoted between a first open position shown in  FIG. 2  and a second collapsed position shown in  FIG. 14B . 
     Left side cylindrical pivot assembly  400  is constructed in an identical manner, and operates in the same manner as left side cylindrical pivot assembly  200  so that a detailed description thereof is omitted, except that left side cylindrical pivot assembly  400  is inverted 180 degrees from left side cylindrical pivot assembly  200 . 
     As shown best in  FIGS. 22-29 , transverse pivotable connection arrangement  24  includes a right side pivot connection  500  for pivotally connecting together lower and upper right side cylindrical pivot assemblies  100  and  300  for transverse pivotal movement. Specifically, right side pivot connection  500  includes a lower circular backing plate  502  of the same diameter as inner cylindrical housing  102  and positioned coaxially at the rear, inner facing surface of inner cylindrical housing  102 . A lower pivot mounting housing  504  has its lower end fixed to the upper surface of lower circular backing plate  502  and forms a continuation of lower circular backing plate  502 , while also extending outwardly from the upper end thereof in the axial direction thereof. Lower pivot mounting housing  504  has a bottom arcuate surface  506  of the same radius as cylindrical housings  102  and  104 , and is positioned directly above cylindrical housings  102  and  104 . 
     Two parallel arcuate slots  508  and  510  are formed through bottom arcuate surface  506  for receiving upper arcuate projections  116  of cylindrical housings  102  and  104  so as to prevent axial displacement of cylindrical housings  102  and  104  relative to each other. The ends of arcuate slots  508  and  510  function also to limit the arcuate travel of upper arcuate projections  116 , and thereby, the rotational movement of cylindrical housings  102  and  104 , and first and second U-shaped tube assemblies  26  and  28  connected thereto. 
     Three parallel, spaced apart finger plates  512 ,  514 ,  516  extend upwardly from lower pivot mounting housing  504 . 
     Right side pivot connection  500  further includes an upper circular backing plate  522  of the same diameter as inner cylindrical housing  302  and positioned coaxially at the rear, inner facing surface of inner cylindrical housing  302 . An upper pivot mounting housing  524  has its upper end fixed to the lower surface of upper circular backing plate  522  and forms a continuation of upper circular backing plate  522 , while also extending outwardly from the upper end thereof in the axial direction thereof. Upper pivot mounting housing  524  has an upper arcuate surface  526  of the same radius as cylindrical housings  302  and  304 , and is positioned directly below cylindrical housings  302  and  304 . 
     Two parallel arcuate slots  528  and  530  are formed through bottom arcuate surface  526  for receiving lower arcuate projections  316  of cylindrical housings  302  and  304  so as to prevent axial displacement of cylindrical housings  302  and  304  relative to each other. The ends of arcuate slots  528  and  530  function also to limit the arcuate travel of lower arcuate projections  316 , and thereby, the rotational movement of cylindrical housings  302  and  304 , and first and second U-shaped tube assemblies  256  and  258  connected thereto. 
     Two parallel, spaced apart finger plates  532 ,  534  extend downwardly from upper pivot mounting housing  524 , and are positioned between finger plates  512 ,  514 ,  516 . Each of finger plates  512 ,  514 ,  516 ,  532 ,  534  includes a through opening  536  which are all in alignment with each other, and a pin  538  ( FIG. 27 ) is positioned within all through openings  536  to permit transverse rotation or pivoting of upper right side cylindrical pivot assembly  300  relative to lower right side cylindrical pivot assembly  100 , between the pivoted positions shown in  FIGS. 2-7  on one hand, and  FIGS. 8-13  on the other hand. 
     Transverse pivotable connection arrangement  24  further includes a transverse pivoting adjustment arrangement  600  at the left side of adjustable incline sleeper  10  and connected with left side cylindrical pivot assemblies  200 ,  400  in order to move left side cylindrical pivot assemblies  200 ,  400  toward and away from each other, while right side cylindrical pivot assemblies  100 ,  300  are pivoted relative to each other by right side pivot connection  500 . 
     As shown best in  FIGS. 15-17 and 30 , transverse pivoting adjustment arrangement  600  includes a housing  602  mounted to the outer axial surface of outer cylindrical housing  204  of lower left side cylindrical pivot assembly  200 . An arcuate cowling  604  extends inwardly from the upper end of housing  602  immediately above cylindrical housings  202  and  204 . Two parallel arcuate slots  608  and  610  are formed through the bottom arcuate surface  606  of arcuate cowling  604  for receiving upper arcuate projections  216  of cylindrical housings  202  and  204  so as to prevent axial displacement of cylindrical housings  202  and  204  relative to each other. The ends of arcuate slots  608  and  610  function also to limit the arcuate travel of upper arcuate projections  216 , and thereby, the rotational movement of cylindrical housings  202  and  204 , and first and second U-shaped tube assemblies  26  and  28  connected thereto. 
     Housing  602  includes a vertically oriented opening  612  therethrough through which an adjustment rod  614  is slidably positioned. The upper end of adjustment rod  614  is fixed in a housing  616  which is fixed to the outer axial surface of upper left side cylindrical pivot assembly  400 . Adjustment rod  614  includes a plurality of spaced apart openings  618  therethrough. It will be appreciated that this construction can be reversed in that housing  602  is mounted to upper left side cylindrical pivot assembly  400  and housing  616  is mounted to lower left side cylindrical pivot assembly  200 . 
     Housing  602  includes a first lower chamber  624  to the outside of opening  612 , and a second lower chamber  626  to the outside of first lower chamber  624  and separated from first lower chamber  624  by a vertical wall  628 . Vertical wall  628  has an opening  630  which serves as a guide, as will now be discussed. 
     A parallelepiped slide  640  has a retaining pin  642  at one end thereof, with slide  640  being slidingly received within the first and second lower chambers  624  and  626 , and guided horizontally by opening  630  in vertical wall  628 . The opposite end of first lower chamber  624  includes an opening  632  through which retaining pin  642  is slidably received, and which is adapted to engage within a respective opening  618  in adjustment rod  614 . A coil spring  646  is positioned within second lower chamber  626  and engages the end of slide  640  which is opposite retaining pin  642 , so as to normally bias retaining pin  642  through opening  632  in first lower chamber  624 . In this manner, retaining pin  642  can be selectively positioned in a respective opening  618  so as to adjust the vertical separation between left side cylindrical pivot assemblies  200  and  400 . 
     In order to move retaining pin  622  out of a respective opening  618 , so as to enable vertical adjustment between left side cylindrical pivot assemblies  200  and  400 , slide  640  is provided with a vertical opening  648 , with the wall defining the vertical opening  648  which is closest to coil spring  646 , being inclined to form a wedge surface  650 . 
     A release member  652  slidably extends upwardly through the lower end of first lower chamber  624 . Release member  652  includes a pushbutton  654  which extends downwardly out from first lower chamber  624 . Opposite retaining fingers  656  extend upwardly from pushbutton  654 , each including a catch  658  at the free end thereof for engaging within a respective ledge (not shown) in first lower chamber  624  to prevent escape of release member  652  from first lower chamber  624 , while permitting sliding movement of release member  652  in first lower chamber  624 . 
     A finger  660  extends upwardly from pushbutton  654  and includes a wedge surface  662  for engaging with wedge surface  650  of slide  640 . 
     In order to adjust the distance of upper left side cylindrical pivot assembly  400  relative to lower left side cylindrical pivot assembly  200 , pushbutton  654  is pressed upwardly so that wedge surface  662  engages wedge surface  662  to move slide  640  to the right in  FIG. 17  against the force of coil spring  646 , thereby moving retaining pin  642  out of the respective opening  618  in adjustment rod  614 . Since adjustment rod  614  is no longer restrained, upper left side cylindrical pivot assembly  400  can be moved vertically relative to lower left side cylindrical pivot assembly  200 , to adjust the transverse inclination of upper pivotable support frame  18  relative to lower pivotable support frame  16 . When the desired inclination is achieved, pushbutton  654  is released, whereby coil spring  646  biases slide  640  to the left in  FIG. 17 , whereupon retaining pin  642  engages within another opening  618  of adjustment rod  614 , to maintain this new vertical separation between left side cylindrical pivot assemblies  200  and  400 . 
     With the arrangement described above, when the infant is napping or crying, connecting tube sections  26   c ,  28   c  are rotated to the position shown in  FIG. 2 , and adjustment rod  346  is moved down to its lowest position as shown in  FIG. 2 . In this position, the infant is in a horizontal sleeping position and can be safely rocked back and forth in a transverse direction, that is, between the left and right sides. 
     When it is desired to feed the infant, connecting tube sections  26   c ,  28   c  are rotated to the position shown in  FIG. 8 . In this position, stop extensions  50  are supporting adjustable incline sleeper  10  so as to prevent rocking thereof. At the same time, adjustment rod  614  is moved to an upper position such that left side cylindrical pivot assembly  400  is moved away from left side cylindrical pivot assembly  200 , whereby the infant is in a partially inclined position, which facilitates feeding of the infant. 
     It will be appreciated that various modifications can be made to the invention within the scope of the present claims. For example, a curved arm  700  having a mobile  702  at the upper free end thereof can be mounted to adjustable incline sleeper  10 . One manner of mounting curved arm  700  is shown in  FIG. 1  by providing a gap in flexible body covering attached to connecting tube section  256   c , whereby the lower end of curved arm  700  can be clamped onto connecting tube section  256   c . Another manner of mounting curved arm  700  is shown in  FIG. 31  in which the lower end of curved arm  700  telescopically receives the upper end of adjustment rod  614 . 
     Having described a specific preferred embodiment of the invention with reference to the accompanying drawings, it will be appreciated that the present invention is not limited to that precise embodiment and that various changes and modifications can be effected therein by one of ordinary skill in the art without departing from the scope or spirit of the invention as defined by the appended claims.
