This invention relates to new and useful improvements in mattresses.

More specifically, the present invention proposes the construction of an improved mattress for home use in connection with a conventional bed and spring and. which is provided with means for raising the head end and/or the foot end in a manner to meet the needs of the occupant or occupants of the bed.

Still further, the present invention proposes characterizing the mattress by superimposed suitably padded upper and lower mattress layers between which a substantially co-extensive rigid plate is interposed and which is provided with the means for raising the head end and/or the foot end of the upper of the mattress layers to suitably support the bodies of the occupant or occupants of the bed.

The present invention is further characterized by the fact that a headboard is `pivotally mounted on the rigid plate beneath the head end of the upper mattress layer and which is resiliently urged to an inclined position in a manner to raise the head end of the upper mattress layer i to support the head and shoulders of the occu- 'f pant or occupants of the bed for reading or the like.

As a further object, the present invention proposes providing the rigid board adjacent the foot end thereof with means for raising the foot end fof the upper mattress layer in a manner to support the legs and feet of the occupant or cocu pants of the bed in an elevated position.

Still further, the present invention proposes constructing the means for raising the foot end headboard to raise the head end of the uppermattress layer and/or for releasing the means for raising the upper mattress layer at the foot end thereof.

Still further, the present invention proposes constructing the mattresses forms characterized by different means for raising the upper mattress layer at the foot end thereof.

It is a further object of the present invention to construct mattresses of the type disclosedy in two different .2 Y which are simple and durable, which are effective for their intended purposes and which can be manufactured and'sold at a reasonable cost.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

detailed view of a por- The mattress, according to the first form of the present invention, shown in Figs. 1 to l2, includes an upper mattress layer 26 and a lower mattress layer 2|. The mattress layers 26 and 2| are coextensive with the upper layer 26 superimposed on the lower layer 2|. Each of the mattress layers 23 and 2| is alike in construction having an outer tick 22 enclosing the usual padding material 23 which may or may not include inner springs as desired. A joining strip 24, formed of the same material as the outer tick 22 of the mattress layers, is engaged about the periphery of the layers and joined thereto by the usual stitches 25 extended about the peripheryy of the mattress layers, see Figs. 6 and 7. The joining strip 24 functions to hold the upper mattress layer 26 superimposed on the lower mattress layer 2l.

A rigid plate 2B is inserted in position between the adjacent faces of the mattress layers 26 and 2|. The rigid plate 26 may, if desired, be secured to the lower mattress layerv 2|l to prevent shifting of the plate 26 relative to the. layers 23 and 2|. However, frictional contact between the plate 26 and the mattress layers is deemed sufficient to retain the plate 26 i'lxedly in place be tween the mattress layers. 26 and` 2|. Ther plate 26 is preferably formed of a lightweight material such as wood, one of the lightweight non-cor" rosive metals or a synthetic resinous material.

The plate 26, at the head end o1" the mattress, is formed with an undercut top tace forming a space in which a headboard 21 is located, see Figs. 4, 5, and 11. At its edge nearer the foot of the bed, headboard 2-1 is pivotally attached to the plate 26 by meansof hinges 28.

The hinges 28 have one of their' leaves secured to the plate 26 and their other leaves secured to the headboard 21,. The headboard 21 is formed of the same material as the plate 26. Elongated leaf springs 29 are located between the adjacent faces of the rigid platev 26 and the head board 21 and along the outerI edges of the. headboard. The leaf springs 2.3i each have. one end secured to the plate 2-6 by means of rivets 30. The attached ends` of the leaf; springs 29 are located adjacent the pivoted edge of the headboard 21. The free. ends of the leaf. springs 29 engage the bottom face of the headboard 21 and urge it into an upwardly inclined position supporting the head end of thev upper mattress layer 26 in the inclined position `shown in Figs- 3` and 5 to similarly support thel head' and shoulders of the occupant or occupants of the bed provided with the mattress. The joining strip 2'4 at the head end of the mattress is provided with a pleated area 2f.a which expands when the head end of the upper mattress layer 20 is raised by the headboard 2-1. The pleated area 24a can be integrally formed with the joining strip 24 or may be a separate piece of pleated material set into a slit formed inthe joining strip 24', so as to expand when the head end of the upper mattress layer 20 is raised.

Electrically controlled means is provided for holding the headboard in a lowered position against the normal action of the leaf springs 29. The electrically controlled means is characterized by a single solenoid 3| xedly mounted in a recess 32 formed in the plate 26 midway of its longitudinal side edges. The solenoid 3| is located below the free edge of the headboard 21. The solenoid 3| has a metallic. core S3 arranged to slide parallel to the length of the plate 23 and provided at its free inner end withl a beveled end 4 34 for engagement with a complementary bracket 35 secured to the bottom face of the headboard 21.

As best shown in Fig. l0, the bracket 35 has a depending portion formed with an opening 36 into which the beveled end 34 of the core 33 extends to hold the headboard 21 in the lowered position.

Adjacent its beveled end 34, the core 33 is formed with an enlarged ange 31 and is sleeved by a coil spring 33. The coil spring 38 operates between the flange 31 and the adjacent end of the solenoid 3| to hold the beveled end of the core 33 in engagement with the opening 36 of the bracket 35. The end of the core 33 remote from the beveled end 34, is formed with an enlarged headV 33 to hold the core from being completely pulledY out` of the solenoid 3| by the action of the spring 38. Normally, the core 33 functions to hold the headboard 21 in the lowered position shown in Figs. 1, 2, 4 and 10. Circuit means, to be hereinafter described, are provided for moving the core 33 against the action of the spring 38 to move its beveled end 34 out of the opening 36.. Immediately, the springs 23 function to pivot the headboard 21 upward to raise the head end of the upper mattress layer 23 to the raised position shown in Figs. 3 and 5. To again lower the headboard 21 and the head end of the upper mattress layer 2! they must be manually pushed down until the beveled end of the core 33 snaps into the opening 33v of the bracket 35.

Means is provided for raising the foot end of the upper mattress layer 23 to similarly raise the legs and thighs of the occupant or occupants of the bed equipped with the mattress. The raising means for the foot end of the upper mattress layer 26 is characterized by a flat platform 40, see Figs. 4 to '7, superimposed above a thickened foot end portion 26a of the rigid plate 2S. Depending from the bottom face ofV the platform 46, at the four corners thereof, there are vertical posts 4|.

The posts 4| are depended slidably through complementary holes 42 and 43 formed in the plate 26 and the foot end of the bottom mattress layer 2|, see particularly Fig. 9. The hole 43 of the bottom mattress layer 2! is reinforced by tubes of cloth material stitched at their top and bottom ends to the tick 22 of the lower mattress layer 2|. In the lowered position of the platform 40, the posts 4| depend from the bottom face of the lower mattress layer 2| and through the openings of the spring of the bed upon which the mattress rests. If the bed is equipped with a boxspring, it must be formed with suitable openings to accommodate the depending ends of the posts 4|.

The outer longitudinal edges of the rigid plate 26 is formed with cutouts 4J! in which pairs of arms 45 are located. The outer ends of the arms 45 are pivotally supported on trunnions it@ which extend from the material of the plate into the cutouts lit. The free ends of the arms @5 are formed with rollers 41 for rolling on the bottom face o the platform d0. Stiff springs 48 are positioned within the cutouts 43 beneath each of the arms t5. Each of the springs iihas one end secured by rivets 39 to the material of the plate 26 at the base of the cutouts 44. The other ends of the spring 438 bear against the bottom edges of the arms @5 urging the arms 35 into the upwardly inclined positions shown in Figs. 3, 5 and '7, raising the platform and the foot end of the upper mattress layer 23 horizontally. As in the case ofthe head end of the mattress, the

joining strip 24 at the foot end is formed with a pleated area 24b which permits the upward raising of the platform 40 and the foot end of the upper mattress layer 26. Such upward movement is arrested by complete expansion of the pleated area 24b of the joining strip 24.

Electrically controlled means is provided for holding the platform 46 in the lowered position shown in Figs. l, 2, 4 and 6 against the action of the springs 48 on the bottom edges of the arms 45. That means comprises a solenoid 49 mounted on the top face of the plate 26 immediately adjacent the posts 4l at opposite corners of the platform 46. The solenoids 49 have cores 56 arranged to slide toward and away from the respective posts 4I. Springs 5I operate between pins 52 extended upward from the solenoids 49 and pins 53 extended upward from the ends of the cores 59 remote from the posts 4I. The springs 5I act in contraction and urge the cores 56 into contact with the respective posts 4I to extend into complementary niches 54 formed in the sides of the posts 4I to hold the platform 4B in the lowered position shown in Figs. 4 and 6. Circuit means to be hereinafter described, is provided for energizing the solenoids 49 to withdraw the cores 56 from the niches 54 against the action of the springs 5|. That functions to free the platform 49 to be raised by the action of the springs 48 on the arms 45. To again lower the platform, the foot end of the upper mattress layer 20 must be manually pressed downward until the cores 50 snap into niches 54.

Support means is provided for that portion of the upper mattress layer 20 Where it slopes downward from the platform 40 in the raised position thereof. The support means is characterized by a base member 55 supported to slide longitudinally on the top face of the fixed plate 26. Superimposed on the base member, there is a topv member 56 pivoted to the base member 55 by means of hinges 51. Leaf springs 58 are secured to the bottom face of the top member 56 at its edge remote from the hinges '51 by means of rivets 59.

The free ends of the leaf spring 58 bear against the top face of the base member 55 urging the top member 56 into the inclined position shown in Figs. 5 and '1.

Secured to the bottom face of the base member 55, there is a pair of laterally spaced longitudinally extending racks 60. The racks 66 slide in parallel longitudinally extending grooves 6I formed in the top face of the plate 26. Between the grooves 6! the thickened foot portion 26a of the plate 26 is formed with a hollow 62 in which electrically controlled means is provided for moving the base member 55 back and forth relative to the platform 40. The electrically controlled means is characterized by end aligned opposed solenoids 63 and 64 between which a single core 65 is slidably extended. When the solenoid 63 is energized, the core 65 is moved away from the foot end of the mattress and when the solenoid 64 is energized, the core 65 is moved toward the foot end of the mattress. The circuits for controlling the energization of the solenoids 63 and 64 will be hereinafter described.

The bottom face of the core 65 is formed with rack teeth 66 which mesh with a small pinion 61 fixed to the shaft 6B rotatively supported between the side walls of the hollow 62. Fixed on the shaft 68 to one side of the pinion 61, there is .a larger pinion 69 which in turn meshes with a smaller pinion 10 mounted on a second shaft 1| rotatively extended between the opposed walls of the hollow 62. The pinion 10 in turn drives another small pinion 12 fixed to a shaft 13 which has its ends extended beyond the racks 66 and rotatively supported on the opposed side walls: of the hollow 62. Beneath each of the racks 6l)y the shaft 13 carries a large gear 14 which meshes with the racks 60. The gears 14 are both of the same size.

y The gear train interposed between the core 65 and the racks 66 provides the solenoids 63 and 64 with a mechanical advantage for moving the base member 55 and its pivotally mounted top member 56 back and forth relative to the platform 40.

In the lowered position of the platform v4l), the top member 56 is held lowered onto the base member 55 against the action of the leaf springs 58 by the same means which holds the platform 46 lowered. When the platform 40 is free to be raised by the action of the springs 48' on the arms 45, the springs 56 are also freed to raise the top member 56 relative to the base member 55. In the completely raised position of the platform 46, the solenoid 63 is then energized to move the base member 55 and the top member 56 from beneath the platform 46 and into position beneath the downwardly inclined portion of the upper mattress layer 26, as shown in Figs. 5 and 1. 'Ifo move the base member 55 and the top member 56 back into position beneath the platform 49, the solenoid 64 is energized. When in position beneath the platform 46 pressures applied to the top mattress layer 26 to lower the platform against the action of the spring 48 will also lower the top member 56 against the action of the springs 58.

The electrical circuits for controlling the solenoids 3 I, 49, 63 and 64 are shown in the schematic wiring diagram of Fig. l2. Those circuits are operated from a single control box 15 separate from the mattress to be positioned on a night table or the like within convenient reach of the occupant or occupants of the bed. The control box 15 has one push button 16 for energizing the solenoid 3 I, another push button 11 for energizing the solenoid 63, another push button 18 for energizing the solenoid 64 and a last push button 19 `for energizing the solenoids 49 in unison.

Extending from the control box 15 there is a lead-in wire 60 provided at its free end with a plug 8l for insertion into a conventional outlet receptacle for supplying the required electric current. The Wire includes the usual parallel leads 82 and 83. Each of the push buttons 16, 11, 18 and 19 has a pair of contacts and within the control box 15, the lead 83 has branches connected to one contact of each of the push-buttons. The lead 82 extends through the control box and out again into the mattress where it is sub-divided into five branches 82, 82h, 82, 82d and 82e. The branch 62a goes to one side of the solenoid 3l. The branch 82b is connected to one side of the solenoid 63 and one side of the branch 62c is connected to one side of thel solenoid 64. The branches 82d and 82e are connected respectively to one side of the solenoids 49.

vExtended from the other contact of the push button 16, there is a lead 84 which is connected to the other side of the solenoid 3| so that when the push button 116 is pushed inward the solenoid 3| is energized to free the headboard 21. A lead 85 extends from the other contact of the push button 11 and is connected to the other side of the solenoid 63 for energizing that solenoid when the push button 11 is pressed inward to move the ense-,595

Abase member 55 and its top member 56 outfrom beneath the platform .49. A lead 86 extends-from the other contact of lthe push button 18 and `is connected -to the other side of the solenoid 64 for energizingthat solenoid when the push button 18 is pressed inward to move the base member 155 and its top member 5t back into position :beneath the platform. Extending from the other contact of the push button 79 there is a lead 81. rIhe lead 8l is extended into `the mattress 'and divided into branches connected to the other 'side of each of the solenoids 49.

Thus, .when the push Vbutton i9 is pushed inward, the two solenoids 49 will be energized to .withdraw vtheir respective cores 50 to free the :platform 4i! to be raised by the action vof the `springs i8 on the arms .45.

The leads 52, `81|, 85, 86 and 81 where they extend between the control box 'l5 and the mattress are embodied in a single cable 88.

.The modification of the invention shown in Figs. 13 Vto lediffers from the previous form in the construction .of the means associated with the fixed plate 2B' for raising the foot end of the upper mattress layer 2D. The head endof the plate is provided with the same pivotally mounted headboard 2l for raising the head end of the upper mattress layer 29.

As in the previous form of the invention, the fixed rigid plate 2-5' isformed adjacent the foot vend thereof with a thickened portion 26b having a hollow 90. -Posiitoned within the hollow 99, Vthere is a U-shaped member 9| having spaced side arms 92 positioned nat against the side walls of the hollow 99. The free ends of the side arms 92 are pivoted to the opposed side walls of the hollow 99 by end aligned pins 93 so that the U-shaped member 9| can pivot in and out of the hollow 99. The opposite -ends of the side arms 92 are joined by an integral intermediate arm which forms a platform 94 which is fixed relative to the side arms 92. Extended transversely between the side arms 92 inward of the platform y91S, there is a group of platforms 95. At their ends, the platforms 95 are provided with depending lugs pivotally attached to the inner faces of the side arms 92 by means of pivot pins 95 so that the platforms 95 can pivot relative to the .side.arms-.92. .Elongated leaf springs 91 are posi- .tioned within the hollow beneath each of the side arms 92 of the .IJ-shaped member 9|.

The leaf springs 9i have one of their endsattached to the bottomwall of the hollow by means vof rivets .9%. The free ends of the leaf springs .91 bear againstthe bottom edges of the side arms S2 to urge the U-shaped member 9| out of the .hollow 99 into the inclined position shown in Fig. 14. When the Ushaped member 9| `is in the inclined position, the free edges Yof the .platforms -95 rest on pins 99 extended inward from the -inner faces of the side arms .92 of the U- shaped member. In the lowered position of the 1U-shapedmemberi, the free edges of the .platforms 95 are held from pivoting upward .by ledge members v| iicarriedby the free edges of the two platforms remote from the xed platform 94. 'In the vraised Vposition of the U-shaped member .9|, the platforms 94 and-95 assume the stepped formation shown `in Fig. 14 to support .the foot Iend portion vof the upper mattress layer 20, to similarly support the legs andhips of the occupant or occupants of the bed provided with the mattress. Thesides of the joining strip .24', at

l.the sides-of the mattress aligned with the hollow `9|) of :thegrigid :plate 26 `is 'formed withvpleated `the core |03 has an enlarged flange |55.

vrelease of the headboard 27.`

areas 24 -which permit the raising of the .foot .end portion of the upper mattress layer 20. Up- -ward movement of the side arms Y92 of the .U-

shaped member 9|, under the influence `of the springs 9i, is arrested upon complete extension of the pleated areas 24C.

Electrically controlled means is provided for holding the U-shaped member 9| in a lowered position shown in Fig. 13 against the action of the springs 91. The holding means is best illustrated in Fig. l5, and includes a solenoid IUI fixedly mounted within a recess il2 in the rigid plate 26 which opens into .the hollow 9.0 midway of the longitudinal sides of the rigid plate 26'. The solenoid |9| supports a core v|03 forsliding `movement toward and away fromv the platform vtil.

The core |93 has an upwardly faced beveled end |64 for engaging the top face of the platform 94, as shown in Figs. i3 and 15, to hold the U- shaped member 9| lowered vagainst the action of the leaf springs 9i. Adjacent its'beveled end, A coil spring |539 .is wound'about the core |93 and operates between the ange 95 and the adjacent end of the core 63 for urging the core into its extended position in which the beveled endl |04 engages the top face of the platform 94. The end of the core |93 remote from the beveled end |94 has an enlarged head |01 for holding the core |93 from being shot out of the solenoid mi by the spring |95.

Normally, the spring |95 holds the core' |03 extended, as shown in Figs. 13 and 15, to engage the top face of the fixed platform 9d to hold the U-shaped member 9| lowered against the action of the spring |55. The solenoid |9| can be energized by circuit means to Vbe presently described, To withdraw the core ita against the action of the spring .|59 to free the U-shaped member 9| to be lraised by the springs 91 to the position shownin Fig. 1.4 in which the foot end portion of the upper mattress layer 29 will be raised. To relower the foot end portion of the upper mattress layer 29, the same is manually pressed downward pivoting the U-shaped member 9| into the hollow 99 against the action of the springs 97. The outer edge of the xed platform @d will snap past the beveled end |95 of the core |93 to again maintain the U-shaped member 9| in its lowered position until the solenoid lili is again energized.

The energizing circuit for the form of the invention illustrated in Eigs. 13 to 16 is shown vin conjunction with Fig. i3. The circuit includes a master control box 15 having a push button 15 and a second push button |68.

As in the previous form of the invention, each of the push buttons 75 and |68 has a pair of contacts. The electric wire 8f3' extendingfrom the plug 8| to the control box l5 includes the leads 82 and 83. Within the control boX 15, the lead 83 has branches connected to one of the contacts of each of the push buttons VM5 and i-. The lead 32 extends through the control box l5 into the mattress where it has separate branches 82X and 825'. rihe lead 82X is connected to one side of the solenoid 3| which controls the The lead 82Y is connected to one side of the solenoid 0|. A lead 84 extends from the other side of the push button 'it to the other side of the solenoid 3| so that when the push button 'I6 is pressed inward, the solenoid 3| will `be energized to free the headboard 2l to be pivoted upward. Likewise, a lead |09 extends from the other Contact acreage 9 of the push button |08 to the other side of the solenoid ll to cause the solenoid lill to be energized to release the U-shaped member 9| to pivot upward when the push button |08 is pressed inward.

The leads 82', 84 and H39, where they extend from the control box l to the mattress, are embodied in a single cab-le H0, just as in the rst form of the invention.

Rested on the top face of the mattress at opposite sides of the foot end thereof, there are pillows As best shown in Fig. 16, the pillows I|| are of truncated triangular shape. The pillows are provided to function as guides for indicating when the occupant or occupants of the bed equipped with the mattress, have their legs located directly in the center of the mattress.

In all other respects, the form of the invention illustrated in Figs. 13 to 16 is similar to the first form and like reference numerals are used to identify like parts of the invention.

From the foregoing description, it is apparent that the mattresses of the present invention provide convenient means for raising either or both the head end or the foot end of the mattresses to similarly support the head and shoulders or the legs and hips of the occupant or occupants of the bed equipped with the mattresses. The mechanisms employed for holding the parts of the mattresses in their raised positions are resilient in their formation so that the mattresses are not rigidly supported in their raised positions but rather have certain amount of play to conform themselves to the particular needs of the occupant or occupants of the bed.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as set forth in the appended claims.

Having thus 'described my invention, what I claim as new and desire to secure Iby United States Letters Patent is:
