longitudinal beams

36 and 37.

As shown in FIG. 8, the box spring assembly Section 31 has a rigid base 63, preferably of plywood. Secured to the top edges of the base 63 are angle irons 64. Upright edge members. 66 are attached to the angle irons to define a cavity for a plurality of spring units 67. The edge members and spring units are covered with suitable padding 68. A fabric covering 69 covers the top and sides of the box spring assembly Section 31. The box spring assembly section 32 is constructed in a similar manner.

As shown in FIGS. 6 and 10, the adjacent corners of the box

spring assembly sections

31 and 32 have

upright arms

71 and 72 that are pivotally joined together at their upper ends forming hinge assemblies 33. The adjacent springs across the box spring assembly can also betcoupled together to form a continuous transverse hinge across the box spring assembly. The padding 68 and the covering is continuous on the top of the entire box spring assembly 29.

A transverse counter weight 73 is connected with a pair of cables 74 to the

frame members

56 and 57 to aid in the upward and forward movement of the forward section of the bed. The cables 74 are trained over pulleys 76 secured to the top wall 47 of the cabinet 27.

A cross beam 77, shown in FIGS. 6, 7 and 10, extends between the

side walls

44 and 46 across the bottom of the housing. The cross member or beam 77 has a pair of

steps

78 and 79 having ramps and shoulders for the

foward wheels

38 and 39. As shown in FIG. 10, the

wheels

38 and 39 are positioned over the crest of the ramps, thereby holding the bed and lounge unit in the lounge position. The bed and lounge unit 20 can be held in the lounge position, as shown in FIG. 10, with releasable locks or spring biased detents (not shown) mounted on the

side walls

44 and 46 and engageable with the side beams 36 and 37. The cross beam 77 can be removed or positioned so that it does not obstruct the movement of

wheel assemblies

38 and 39.

A seat cover or seat cap 82 is positioned over the seat portion 31 of the mattress. Seat cover 82 has a forward or front portion 83 that extends downwardly and is releasably attached to the front panel 42. The seat cover 82 has downwardly directed sides and back or rear portion 84 that extends under the back rest 26. A transverse plate 86 is adjustably mounted on the bottom and rear side of the bake rest. As shown in FIG. 7, the plate 86 has a pair of slots 87 receiving releasable fasteners 88 whereby the plate can be adjusted relative to the back rest 26. FIG. 11 shows the lower edge of plate 86 engaging and holding the cover 82 on the seat 22.

As shown in FIGS. 6 and 10, the back rest 26 includes a support panel 89 attached to the lower edge of the front panel 48 with a transverse hinge 91. A pair of pivoted friction linkages 92 connected to the

side walls

44 and 46 and the panel 89 are used to retain the back rest in its adjusted positions, shown in broken lines in FIG. 6. Linkages 92 can be arranged so that the back rest 26 will automatically move forward and up when the mattress 28 is moved from the seat position to the bed position.

In use, with the bed and lounge unit 20 in the seat position shown in FIGS. 1, 2 and 10, the mattress 28 is transversely bent approximately across the mid-portion with the head portion extended upwardly to the cabinet 27. The top section 31 of the box spring assembly is supported with the

rollers

58 and 59 on the upper ends of the guide rails 51 and 52. The

wheels

38 and 39 are in their lock or hold positions over the step or ramps 78 and 79 in the cross beam 77. The space between the head portion of the mattress and panel 89 can be used to store pillows and extra blankets.

The conversion of the bed and lounge unit 20 from the seat position to the bed position is accomplished by initially raising the back seat 26 as shown in broken lines in FIG. 6. The handle 43 is then used to pull the mattress, forcing the

wheels

38 and 39 over the

steps

78 and 79. The mattress moves out to its bed position shown in FIGS. 3, 4, and 6. When the

rollers

58 and 59 engage the stops 54 at the end of the guide rails 51 and 52, the mattress 28 is in its horizontal or prone position. The back rest 26 is then moved back to its down position, shown in full lines in FIG. 6, to provide a head board for the bed.

Referring to FIGS. 12 to 15, there is shown an arm rest 23 located adjacent one end of seat 22. Arm rest 23 is removably mounted on a support 101 attached to the frame of the seat. The arm rest 24 on the opposite side of the seat is identical in structure and is removably mounted on a similar support.

Support 101, comprises a pair of upwardly directed

arms

102 and 103 connected to a top cross member 104 to form a generally inverted U-shaped structure. The lower ends of the

arms

102 and 103 are secured to inwardly directed

members

106 and 107 secured to the frame of the box spring assembly 29.

The arm rest 23 has a skeleton framework indicated generally at 108 comprising a pair of upright members 109 and-111 positioned in close engagement with outside faces of the

upright arms

102 and 103. A generally horizontal cross member 112 is attached to the upright members 109 and 111 to provide a stop engageable with the top of the cross member 104. The members 109 and 111 are secured to generally

upright side panels

113 and 114. Opposite ends of the.

side panels

113 and 114 are connected to upright ends 116 and 117.

Spacers

118 and 119, shown in FIG. 14, are located between the side panel 114 and the support 101 to minimize the lateral movement of the arm rest 23 relative to the support 101. Side panel 113, upright members 109 and 111 and the

spacers

118 and 119 form an upwardly directed opening or pocket 121 for receiving the support 101. The side panel 113 has a lower opening 122 which permits the arm rest 23 to be located in the pocket 121 in a manner so that the lower edge of the arm rest is located in close proximity with the floor. A suitable cover 123, has a fabric, leather, synthetic material or wood panel surrounding the side panels and ends on 116 and 117.

Located along the top of the arm rest is a cap 124. The cap 124 can be removed for cleaning and repair as well as recovering without disassembling the arm rest. The cap 124 has a base plate 126 supporting an elongated flexible pad 127. A cover 128 positioned over the pad is secured to the bottom of the base plate. Secured to and projected downwardly from the base plate 126 are a pair of positioning blocks 129 and 131. Block 129 extends downwardly adjacent the upright member 109.

In a similar manner, block 131 extends downwardly between the upright member 111 and the end 117.

Elongated rods

132 and 133 secured to the

blocks

129 and 131 extend downwardly through suitable openings in the

bottom plates

134 and 135.

Nuts

136 and 137 threaded on the

rods

132 and 133 secure the cap 124 to the top of the framework. The cap 124 can be readily removed by removing

nuts

136 and 137 and separating the cap from the remainder of the arm rest.

Support means comprising a pair of laterally directed bolts can be used to attach arm rest 23 to the frame of the seat. Nuts on the bolts can be used to fix the position of the arm rest on the bolts and adjust the lateral position of the arm rest 23 relative to the side of seat 22. A block or similar member may be secured to the frame to accommodate the bolts.

While there has been shown and described a preferred embodiment of the combination bed and lounge and removably mounted arm rest of the invention, it is understood that various changes in shape and structure may be made by those skilled in the art without departing from the spirit of the invention.
