l INI/Enron ALEX J'. KATZ ATTR//EX United States Patent O 3,184,765 BEDS Alex l. Katz, Grange, Nul., assigner, by mesne assignments, to Super Sagless Spring Corporation, Amsterdam, NX., a corporation of New York Filed Apr. 7, 1961, Ser. No. 101,386 22 Claims. (Cl. 5-67) This invention relates to beds, and is particularly related to a bed having an articulated bed frame coniprising a head section, a seat section pivoted to the bed section, and a foot section pivoted to the seat section.

An object of this invention is to provide in a bed, an improved bed frame that could be converted from a iiat horizontal position to a position in which the head and back support section would be elevated for viewing television or reading and at the same time the knees would be elevated to a very comfortable position, in which the bed frame would support a mattress and means to lock the bed frame in an infinite number of positions from completely flat to an almost upright position of the head section.

Bed with bed frames having head, seat and foot sections that could be moved from flat to various inclined positions have been known, but such devices as heretofore made were operated either by external sources of power which are expensive, or such devices had to be operated either by another person or required the ccupant of the bed to get out of bed to adjust them which is very inconvenient.

It is hence another object of this invention to provide a bed construction 0f the character described, so constructed that the positions of the sections of the bed frame can be changed solely by the occupant unlocking the lock and shifting his Weight, thereby making the bed less expensive and easy and convenient to operate.

Still another object of this invention is to provide a bed comprising a bed base, a lever pivoted to the bed base for angular movement relative thereto, and a bed frame comprising a head section, a seat section pivoted to the head section, and a foot section pivoted to the seat section, said bed frame being connected to the lever for movement of its sections to various angular positions are relative to the others and relative to said lever, whereby said bed frame in each of the various relative angular positions of its sections, can be moved as a whole relative to the bed base, by moving the lever angularly relative to said head base.

Another object of this invention is to provide, in a bed of the character described, a bed frame for a mattress, said bed frame having a head section and a seat section, said sections being movable from co-aligned positions to angular positions of less than 180, one relative to the other, and means at the pivot corner for said sections, to support the portion of the mattress which overlies the pivot, and which cannot it into the corner or apex of the angle between said sections, whereby the mattress on the bed frame (which bends to Conform to the angles of the sections of the bed frame) is better supported and hence adds to the comfort of the user.

Still another object of this invention is to provide in a bed of the character described, means to lock the lever to the bed base, said means being7 releasable manually, and separate means to lock the bed frame sections against movement relative to each other and to the lever, said latter lock means also being releasable manually and inpedendently of the lever lock means, the construction being such, furthermore, that back lock means are normally in locking condition and are unlocked only while the operator is actuating them, and both said lock means reverting to locked condition when the operator stops actuating them.

"ice

Still another object of this invention is to provide a bed of the character described having means to raise the seat and foot sections to a position higher than the back section, and means to move the bed frame to a position where the head, seat and foot sections are horizontally aligned, means being further provided to hold the outer end of the head section against movement below a predetermined height.

Yet another object of this invention is to provide in a bed of the character described, highly improved means to prevent side sway or movement of the bed frame in the various positions thereof.

A still further object of this invention is to provide in a bed of the character described, highly improved locks for the lever and for the bed sections, said locks including push buttons, and said locks being normally locked, and being released only while the push buttons are depressed.

Yet a further object of this invention is to provide a strong and durable bed of the character described, which shall be relatively inexpensive to manufacture, easy to manipulate, which shall be smooth and positive in operation, and yet practical and etiicient to a high degree in use.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly Consists in the features of construction, combinations of elements, and arrangement of parts, which will be exemplied in the construction hereinafter described and of which the scope of invention will be indicated in the following claims.

FIG. l5 is a cross-sectional view taken on line 15-15 of FIG. 2; `and FIG. 16 is an enlarged, cross-sectional view taken on line 15-16 of FIG. 2.

Referring now in detail to the drawing, l@ designates a bed embodying the invention. Bed itl comprises a bed base 1l. The base 11 comprises a pair of parallel, horizontal, coextensive, symmetrical side members 12 of angular cross section, each having a vertical upW-ardly extending flange 13 at the lower end of which is a horizontal inwardly extending yflange 14. Said side members 12 are supported in end legs 15 and may be interconnected by usual suitable cross-members, not shown.

A head rest board 16 may be fixed to the head ends of .the bed base, extending upward-ly from the side memt bers Iand suitably fixed thereto. At the inside of the head rest 16 is fixed a horizontal -transverse angle shaped member 17 having an inwardly extending flange 18 and a downwardly extending flange 19, for the purpose hereinafter appearing. Member 17 is spaced above the side members 12, `as shown in the drawings.

Fixed to opposed portions of ythe inner sides of the anges 13 of side members 12, somewha-t closer to the head ends than foot ends of said members, as by rivets 24), are brackets21, 21a (FIGS. 2,6, 8).

Bracket 21` has a lower portion 23 contacting the inner side of flange 12, an intermediate outwardly bent portion 24 overlying the upper edge of said flange, and an upper portion v25 ydisposed in a plane outside of said flange, Portion 25 has an opening 26 with opposed flat edges 27 (FIG.` l0), and round opposed edges 28 alternating with edges 27, non-rotatably fitted into opening 26 is a ref duced end hub 29 of a lock housing 3l), having surfaces 27a, 28a contacting said

surfaces

27, 28. Lock housing 3i? has an axial through opening 31 through which passes one end of a :rod 32. Extending from the hub 29 is an enlarged intermediate portion 33 having an outer circular surface 34. Extending from the intermediate portion 33 is button orllange 35 `of greater diameter. Intermediate portion 33 is formed with three equiangularly spaced, :radial drilled holes 36 having inner-frustoconical por-tions 37 extending to the inner surface 31 (formed by the base of the drill point) thereby providing seats for balls 38 dropped into the holes. The balls project through the holes 37a in the seats 37 tocontact the outer surface of rod 32.

The bracket 21a is symmetrically disposed relative to bracket 21` `and is similar thereto except that instead of being formed` with ropening 26 as shown lin FIG. l0, it is formed with a round opening 4t), in which the other end ofrod 32 is journalled. SaidV rod 32 has flattened ends 41 received in ysimilar shaped holes 42 in levers 43. Said ends 41 are riveted over and leversj43 are rotatable with trod 32.

The levers 43 are similar and aligned. Rod 32 is the .axis of rotation for said levers. Each lever has a forwardly extending arm 44, the major portion of which is located in a plane outside of the flane of flange 13. The front end of each lever portion 44 lis offset outwardly, as shown in FIGS. 1 and 7. Extending rearwardly of the pivot points of levers 43 are straight portions 46 in the plane of `portion 44. Extending from eachvportion 46 is an upw-ardly bent portion 47 yfrom which extends an upwardly inclined arm 48. At the upper end of arm 48 is an outwardly offset end portion 49 in the planeof portion 45. As shown in FIGS. 2 and 3, arms 44 and portions 46 of the levers 43 are parallel to side members 12 and located thereabove, in one position of said-levers.

Levers 43 may be rotated in clockwise directions from the position of FIGS. 2 and 3 to the positions of FIGS. 4 and 5.

Rotatably mounted on the intermediate portion 33 of lock housing 3) is a lock actuating arm 50. Arm 56 narrows forwardly. At its rear end ithas an inwardly offset portions 59a formed with anv opening 51 receiving said intermediate portion 33 andsurrounding surface 34 and confining the balls 3S to their openings or drilled holes 36. Opening 51 has three similar segments 52 of 120 each. Each segment is of greater radius at the ends than in the middle. The middle of the segments substantially contact surface 34 of :intermedi-ate poi-tion 33. When the meetingends of the segments 52 are over t the drilled holes 36, the balls 38 may move lradially outwardly and are loose on the rod 32, and said rod to-v gether with levers 43 may rotate.` When saidV arm 5t? is rotated in a ycounter-clockwise direction, `in the manner hereinafter explained,.to its normal position, the middle portions of segments 52 are over the drilled holes 36, and the balls A33 are pressed radially inwardly to project through openings 37a in the ball seals` 37, to grip the rod 32 Iand prevent the lrod `from rotating, .and hence 'also keep the levers 42 from rotating.

Means is provided to ynormally. retain the actuating arm Si) in position for locking levers 43. To this end, there is fixed to ange 13 of the side member which carries bracket 21, asby screws -orrivets 55, an upstanding bracket 56 having at its upper end, an inwardly offset linger 57 formed with an opening 58 receiving a hub 59 fixed thereto and formed with an axial through opening 60 for the purpose hereinafter appearing. Finger S7 overlies the small forward end of actuating arm 51D. Said arm at its small end, has an upstanding finger 61 aligned withhub 59. Interposed between finger 57 and arm 59.

is a coil compression spring 62. Its upper end receives the lower end of hub 59. Its lower end receives finger 61. Thus spring 62 presses down on arm 56 to retain the ,lock in locked condition. It is only when the arm Silis rotated upwardly against the pressure of spring 62, in the manner to be described.hereinaftenthat the lock is released, and the levers 43released for rotation.

Means is provided to control rotation of levers 43 in a clockwise direction looking at the drawing, to raise the forward ends 45'1of the levers. To this` end,there is fixed` to the inner sides of portion 44 of each lever 43, a bracket 65 having a rearwardly extending tongue 66 riveted to said portion as at 67. 'Extending inwardly from the ,forward end of tongue 66 is an intermediate offset 68 from which extends forwardly, a tongue 69 parallel to and spaced from said portions 44 and terminating close to portion 45 `of the lever. Pivoted to tongue 69as by pivot pin 70, is a link 71. Said link 71 has one end 72 received between tongue 69 andlever portion 44. Beyond tongue 69, said link 71 has an inwardly extending offset 72 from which extends the outer end 73 ofthe link, inthe plane of said tongue 69. Tongue 69 is inthe plane of flange 13 of side member 12, .as seen in FIG. 7. Pivoted to the outer end 72 of link 71, as by transverse pivot pin 74are a pair of

parallel links

75, 76 disposed on opposite sides of link end 73.1 The lower ends of

links

75, 76 are oniopposite ends of flange 13 and arepivoted thereto by a common transverse pivot pin 77 located only slightly forwardly of pivot pin when the lever 43 is in its down position. It will now'be understood that levers 43 may be swung up, when the ball lock is released, from the down position of FIG. 2 to the upmost position of FIGS. 4 and 5. The

links

75, 76 being received on opposite sides of link 73, and portion 72 of saidlink, being received between tongue 69 and lever portion 44, serves to stabilize the structure against sidey sway.

When levers 43 swing back,'the bent or curved portions 47 thereof dip below the upper redges'of flanges 13 of side members 12, as seen in FIGS. `4 and 5.

Supportedon and by the levers `43 is abed frame 843 comprising a head or end section 81, a middle or seat section S2 hinged tothe forward end of the head section, anda foot or leg section S3 hinged to the forward end of thek seat section. The head section S1 comprises a transverse angle shaped bar 84 having a top forwardly extending `flange 85 from the rear of which extends downwardly t above the lower edge of llange 36 of the base, and crossbar 84 contacts the upper side of llange 13 of stop bar 17 as shown in FIG. 2 ofthe drawing.

Flange 83 each side bar 87 terminates, at its forward end, short of flange 39 of said bar, as shown in FIG. 1.

The upper ends of portions 49 of the levers 43 contact the inner sides of flanges 89 and are pivoted thereto by pivot pins 95.

The seat section 82 comprises parallel side bars 96 of angle cross-section, each comprising a top, inwardly eX- tending ange 97, and an outer, downwardly extending llange 98. At the far side of the bed, the forward end of flange 89 is pivoted, as by pin 99 to the rear end of adjacent ange 9S. At the opposite side of the bed the

llanges

89 and 98 are interpivoted by a pin (not shown) coaxial with pin 99 but shorter than said pin. Flanges 97 terminate -at their rear ends short of the pivots 99 (FIG. 1).

The bars 96 are interconnected by a pair of spaced cross-braces 9) similar to the cross-brace 96 described above, and located adjacent the outer ends of flanges 97.

Foot section 83 comprises a pair of side-bars 100` interconnected by a front cross-bar 101, all of angle shaped cross-section. Bars 199 have top horizontal ilanges 192 and downwardly extending vertical flanges 103. Cross bar 191 has a top flange 105 and a vertical downwardly extending flange 106.

The rear end of llanges 98 are offset inwardly as at 93a to be located at the insides of llanges 89, as shown in FIG. 11. The forward ends of anges 133 are in planes at the outsides of rear ends of anges 98 as shown in FlG. 15.

Fixed to the inside of each flange 98, adjacent its forward end, is a bar 110 having an inwardly offset portion 111 spaced from the portion of flange 98 which extends beyond ange 97. Fixed to the inside of each flange 193 is a bar 112 having an inwardly oiset portion 113 extending rearwardly beyond flange 102 and spaced from flange 103. Flange 93 is received between flanges 103, 113. Flange 113 is received between flanges 98, 111.

Flanges

103, 98, 113, 111 are pivoted by pivot pin 115. Thus, a pivotal connection and stabilizer is provided for the seat and foot section, to prevent side sway of said sections.

Means is provided to connect the foot section to the levers 43. To this end, the forward ends of levers 43 are connected to the side bars 199 of the foot section by pairs of spaced

links

120, 121. Each link 129 is pivoted at its lower end, to portion 45 of lever 43 by pivot pin 123 and at its upper end by pivot pin 124 to ilange 133 of side bar 192. Each link 121 is pivoted at its lower end to the forward end of lever 43 by pivot 125 and at its upper end to said llange 103 by pivot pin 126. The links 12@ are of greater length than links 121, and more inclined to the horizontal when the bed frame is in the position or" FIG. 2. With such construction, as the foot section 83 is pulled back from position of FG. 2, to the position of FIG. 3, said foot section will incline downwardly and forwardly as shown in FIG. 3.

When the levers 43 are in normal position, with arms 44 horizontal, and with head and seat sections of the bed frame horizontal, the foot section will also be held in horizontal position by links 129, 121. When the foot section is horizontal, the

links

120, 121 are inclined forwardly and upwardly. Pivot points 123, 125 are somewhat urther apart than pivot points 124, 126.

Means is provided to releasably lock bed frame sections 31, S2, 83 against relative movement in any relative angular positions thereof. To this end there is rotatably mounted on pivot pin 99 (at the right side of the bed or the same side that has the releasable lock shown in FIGS. 8, 10, l2) a lock housing 139 similar in shape to lock housing 33. Said lock housing 134B has a through opening 131, through which pin 99 passes.

Pin 99 has flats to engage in an opening with correspending tlats in flange 89 so that pin 99 will not rotate relative to said ange. Lock housing 139 has an outer hub 139a with flats received in a corresponding hole 132 with ats, in portion 93a of `flange 93. Lock housing 139 has an intermediate portion 133 of circular shape formed with three equiangularly spaced, radial, drilled holes 134 having annular seats 135 at their inner ends providing holes 136. Balls 137 in the radial holes 134 seat on the seats 133 and project through holes 136 to contact the pin 99. An enlarged inner hub or button 138 is provided at the inner side of lock housing 139. Rotatably mounted on intermediate hub 133 is the rear end 140 of a lock arm 141. Said rear end 140 has a hole 142 similar to hole 51. lt also presents three equal segmental edge portions of less diameter at the middle and gradually increasing in diari eter toward its ends. When lock arm 141 is in its up position, the mid-portions of the segments are over the drilled holes to press the balls radially inwardly into gripping position relative to the pin 99, thereby preventing rotation of sections 81, 82 one relative to the other. Actuating arm 141 narrows toward its forward end. It is formed, in its upper edge with a notch 144 to accommodate the llat end 91 of one of the brace-bars 90. Upon rotating said arm 141 downwardly in a counter-clockwise direction, the ends of the segments of opening 142 are brought over the drilled holes 134 allowing the balls 137 to move radially outwardly, thereby 'releasing pin 99 and permitting rotation of the bed sections.

Means is provided to normally retain the actuating arm 141 in up or locking position. To this end, a bracket 159 is fixed to the inside of flange 98 of side bar 96 adjacent the forward end of actuating arm 141. Said bracket extends down below flange 93 and has an inwardly extending linger 151. A pin 152 is iixed to the linger 151 and projects upwardly therefrom. Said arm 141 is formed at its front end with a downwardly projecting lug 153 aligned with pin 152. A coil compression spring 155 is interposed between finger 151 and arm 141, said spring receiving said pin 152 at its lower end, and the lug 153 at its upper end.

Flange 97 is formed with a hole 156 directly above the narrow end of arm 141. A push button 157 has its upper end slidably extending through said hole. Said button has an enlarged base resting on the arm 141. The spring 155 normally presses arm 141 upwardly, to retain the lock housing in locking or pin gripping position. However, upon pushing the button 157 the arm 141 is depressed sutlciently to bring the lock housing to releasing position. The lock housing remains in releasing position only as long as the push button is manually depressed. rhis construction makes sure that the bed frame sections will not move accidentally one relative to the other unless and only while the push button 157 is being depressed.

Means is provided to release the lock housing 39 for the levers 43. To this end, there is pivoted to the inside of llange 93 on the same side of the bed as arm 5u, as by pivot 161), alever 161 having a rearwardly extending arm 162 lying beneath flange 93, and a forwardly extending downwardly inclined arm 163. Fixed to the inside of ilange 93 is a bracket 164 having an inwardly offset linger 165 at its lower end formed with an opening in which is mounted a hub 166 formed with a through opening 167. A wire 163 has one end hooked through an opening 169 in arm 162 and passes through opening 167 in hub 166 and then passes down through opening 6) in hub 59, through coil spring 62 and is connected or hooked to arm 53 through an opening 5917 therein. A lexible sleeve 170 receives the wire 163 and is interposed between hubs 166 and 59.

Flange 97 of side bar 96 has a hole 175 in which is slidably mounted a push button 176 similar to push button 157 and overlying arm 162 of lever 161 and contacting said arm. Upon pushing button 17 6, lever 161 is rotated in a clockwise direction (FIG. 5) to cause a pull on wire 16S upwardly to cause the wire to move through sleeve 170 to pull up arm 5t) to rotate the lock housing bushing 3G to releasing position. Such movement compresses spring 62, so that as soon as the operator takes his finger olf the push button 175, said spring will again pull down on the wire 168 to move the arm 5t) back to normal locking position.

It will now be understood that with the levers 43 in their normal positions of FiGS. 2 and 3, button 1'76 may be depressed andthe bed sections moved from the flat horizontal coplanar positions of FIG. 2, to the position of FIG. 3 or to any intermediate position between these two extremes. The bed sections can be locked in any of these positions by taking the finger off the push button 176. The person lying in the bed need merely press down torwardly of pivots 95 (after pushing button 176) and the head section will rotate about said pivots in a counterclockwise direction to cause the forward end of the head section to pull downwardly and rearwardly in the seat section, which, in turn, pulls back on the foot section to cause it to move under control of links 121i, 121. The

push buttons

157, 176 may be provided adjacent their upper ends with grooves receivingsnap rings 157a, 1'76a to prevent the push buttons from falling out of their holes.

A mattress M may be placed on the bed rame.-

Also, usual springs or wires may be provided to interconnect the bars of the bed fram sections to provide a platform support for the mattress.

The position of FIG. 3 may be considered a sitting up position. By keeping the bed frame sections locked, and releasing the levers 143, the bed frame as a whole may be swung back. to the position of FIG. 4. This position may be called a TN. position, that is, a position from which to watch television.

The position of FlG. 2 is for sleeping or lying down flat.

The position of FIG. 5 may be used for heart patients, since the foot section is raised above the .head and back section. This may be called the fully reclined position.

It will now be understood that the levers may be pivotally moved with the bed frame sections locked in various relative inclined positions.

It will be observed that in many positions of the bed frame, the head section has an angular position relative to the seat section of less than 180. kIn FIG. 4, this angle about 90. The mattress M cannot tit into the corner space formed at the junction of the head and seat sections. Means is provided to support the mattress above such corner space, to give ample support to the mattress at such location. To this end there is pivoted to tianges S9 and 9S on each side of the bed, as by

pivots

130, 131 spaced equi-distant from the pivot pin 99, downwardly and inwardly inclined links 132,183, respectively. Supported on pivot pins 184, 185 at the lower ends oi said links, at each side of the bed, is a cradle 190. Each cradle cornprises a pair of similar symmetrical angular portions 191 located in a vertical plane interconnected by a top horizontal portion or flange 192.` The anges 192, as both sides of the bedare interconnected by a cross-brace titl, such as heretofore described.Y As the angle between the head section 81 and the seat section becomes smaller, the top tlanges 192 cut across the cover formed by said sections, and the mattress Mwill be supported at said corner by said cradles 19t), and the mattress will not wedge into such corner. The cradles 1% may be inter connected by wires or springs if desired.

Means is provided to limit upward rotation of levers 43, to prevent links ,'71, 75 from becoming coaligned, to thereby insure that said levers can be swung down again,

and will not be locked in up position by said links. To`

this end, there is fixed to flanges 13 of one side member 12, a stop pin 2Gb which willcontact an underedge of lever t3 as shown in FlGS. 4 and 5, when the levers 43 have reached their maximum ydesired upswing positions. -In suchposition the stabilizing links '71, 75 are still at an angle one to the other.

It will thus -be seen that there is provided an apparatus in which theseveral objects of this invention are achieved and which is wellA adapted to meet the conditions of practical use.

As possibleembodirnents vmightbe made of the above invention, and as various changes might bemade in the embodiment above `set forth, it is to bel understood that all matter herein set forth or yshown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense. f j

lt will be understood that the levers 43 may be rigidly iixed relative to the bed base, or be part of the base instead of being locked thereto, and the sections of the bed frame moved relative to Vthebed base, as shown in FIG. 3.
