Application April 8, 1937, Serial No. 135,632
My invention relates to .a lifting device for lifting bed spring frames and mattresses, and the purpose is to provide a very simple device of this character by means of which the bed spring and mattress of a bed may be tilted or rocked on an axis to raise them to an elevated position for the purpose of giving ready access for the cleaning of the floor under the bed as well as to place the bed spring frame in a position for easily cleaning the springs, bed frame etc.
Devices have been proposed for this purpose but the present invention is an improvement over former devices, especially in that the device may be applied to any type of bed and bed spring now in use because the lifting device requires no modification of the bed structure, nor the spring frame structure. On the other hand, the lifting device does not have to be applied at the factory to the bed spring, nor the bed, but it may be attached if desired by the user, and without even the necessity of using tools for the mounting of the device on the bed.
Another object of my invention is to provide a bed spring lifter which will more eflectively counterbalance the weight of the spring frame and the parts carried by it and readily hold the spring frame in the raised or tilted position while the floor below the bed is being cleaned, or while the various bed springs and frame are being cleaned.
Another object of the invention is to provide a bed spring lifter which may be mounted entirely on the side beams of the bed, thereby eliminating attachment of any of the parts to any cross members of the bed structure.
Another object of the invention is to provide a bed spring lifter which will permit all cross members of the bed structure, other than the head board and the foot board, to be omitted or removed so that when the bed spring frame is in raised position there will be a full clear space in which to move a mop or other cleaning instrument over the floor beneath the bed.
Another object is to make the bed spring lifter detachable from the bed structure and in a simple manner, so that in case of moving, the lifting device may be detached from the bed frame or from the spring frame, or both, to be readily packed for moving purposes.
Another object is to provide a very simple construction of bed lifter having but few parts, and which will be very simple in operation.
I have shown my invention in two different forms, one of which is adapted to be applied to a woodenbed structure while the other is adapted to be applied a metal bed frame.
Other objects and advantages of the invention will be set forth in the following detailed description of my invention.

Figure 10 is a sectional view showing the type of clamp to be used where the longitudinal members of the bed frameare made of tubular metal instead of angular metal.
Fig. 11 is a modified form of clamp for attaching the brackets to the rail strip of a wooden bed frame.
I will first describe the form of device shown in Figures 1 to 7 inclusive. In these figures I have shown a bed structure consisting of. head and foot boards I, 2 and between which are connected the side beams or rails 3, 4 of the bed frame, and where my invention is employed it is not necessary to have'any cross members between these side rails or beams for the spring frame; and if there are such members on the bed they may be removed if desired when my invention is applied thereto. The spring frame is shown as consisting of a rectangular frame work 5 which may be of one piece and comprising longitudinal members 6, 1 extending parallel along opposite sides of the frame, and cross members 8, 9 connected between the side members which, as stated above, may be formed all of one continuous piece of metal.
The cross bars l6 extend between the sid members 6, I of the spring frame, and I have shown helical springs mounted on the spring frame and supporting the mattress l2.
It will be understood that the present invention may be used in conjunction with any type of spring frame and any spring system, and any type of mattress.
Preferably, the present device is so proportioned that it is spaced some distance from the head board and foot board of the bed structure, to leave a large open space for access to the floor when the spring frame is in elevated position. I employ, preferably, two brackets l3 for supporting one side of the spring frame, arranging them spaced apart lengthwise of the bed, but preferably some distance from the footv and head boards. These bracket devices may be both alike and a description of one will apply to both.
Where the two side beams 3, 4 of the bed frame are made of wood, as shown in Figures 1, 2 and 4, these beams are usually of rectangular construction as shown, with their longest diameter extending vertically. Each bracket l3 consists of a U shaped yoke having a wall M which rests against the outer surface of the bed frame beam 3, a wall l5 resting on the top surface of the beam, and a wall |6 extending downwardly and lying against the inner surface of the bed beam 3. These brackets may be slid downwardly upon the beam 3 so that they come to rest in the position shown in Figures 2 and 4 and no bolts or other members are necessary to hold them in place, and so that they will not injure the beam of the bed the part in contact with the bed is covered with soft felt.
There is a bracket l8 like that shown in Figure 3, attached by means of a rivet l1 pivotally to a laterally extending plate H! on each bracket l3. The bracket |8 has a slot 20 extending inwardly from one end, which is adapted to receive one wall 2| of the angle metal member 1 which forms one of the side beams or rails of the spring frame with the other wall 22 of this angle metal member extending downwardly against the inner side of the portion 23 of the bracket |8 which is bent at right angles to the main portion thereof. The bracket |8 also has a portion 24 bent at right angles to the main portion and this member has two apertures 25 as shown in Figure 3, to receive the pivot pins 26 and 21. The first of these pivot pins pivotally attaches to the member 24 a locking key 28 which, when in the lowered position shown in Figure 6, seats against the vertical web 22 of the bar 1 and holds the angle metal bar of the spring frame with its horizontal web 2| disposed in the slot 20. This holds the spring frame in locked relation with the bracket l8 so that they move together upon the pivot H. The
As long as the device is in operation upon a bed, the locking member 28 is in the lowered position shown in Figure 6. This forms a very convenient means for assembling the spring frame at this position with the brackets l8 and with the brackets l3 which are applied to one of the side beams of the bed, and no screws'or bolts are necessary for assembling and disassembling of the spring frame on the supporting brackets.
On the pivot pin 21 there is pivotally mounted an arm 30 having an offset portion 3| and this is adapted to be swung up into the raised position shown in Figure 2, to act as a stop to prevent the mattress and upper portion. of the spring structure from sliding out of place when the spring frame is to be elevated to the position shown in Figures 1 and 2.
When the bed is in position for sleeping purposes the lever arms 36 may be lowered into the position shown in Figure 4, to be out of the way, or in other words, it need only be elevated when the spring frame is to be lifted. When there are two brackets l3 for supporting the spring frame, there are preferably two arms 30 one for each bracket.
It will be understood that the pivot pins I! by which the brackets |3 are pivotally connected with the brackets l3 will be in alignment and that this line will form the axis about which the spring frame swings between the lower position shown in Figure 4 and the raised position shown in Figures 1 and 2.
I have shown clamps 3|, there being two in the drawings, consisting of two plates connected together by bolts 32, the plates being applied to opposite sides of one of the cross bars ID of the spring frame, with one bolt 32 above this bar and the other below it, as shown in Figure 2. It is understood that both these clamps are alike.
There is a longitudinally extending rod 33 passing through the free ends of the clamps 3| and adjacent each end of the pivot rod there is pivotally mounted a lever arm 34. These lever arms, each being of the same length, are pivotally connected by the pins 35 with other lever arms 36 which are preferably longer than the arms 34. These latter lever arms 36 are pivotally connected with the pins 31 mounted in the lower ends of the downwardly extending members 38 of brackets which are mounted upon the right hand beam 4 of the bed frame in Figures 2 and 4. These brackets 39 are attached to the right hand beam 4 of the bed structure in the same manner as the brackets |3 on the left side. Each consists of a vertical wall 46 engaging the outer surface of the right hand beam 4 of the bed frame, of a horizontal wall 4| resting on the top of the beam 4, and a vertical wall 42 extending downwardly and engaging the inner side of the beam 4. From this latter wall there extends horizontally toward the center line of the bed a rest portion 43 on which the longitudinal bar 6 of the spring frame is adapted to rest and the downwardly extending portion 38 to which the lever arm 36 is pivoted is a downward continuation of the portion 43 of the bracket.
There are spiral springs 44 each having one end connected with a pin 45 on the bracket 43 and another end connected with the rod 46 which extends through apertures in the pair of lever arms 36 so that these springs have a tendency to raise the lever arms 36 from the position shown in Figure 4 to the position shown in Figures 1 and 2. There are other spiral springs 41 each having one end connected with the bar 46 and their opposite ends connected with pins 48' which are mounted on the ends of the lever arms 49 which project below the plane of the pivot points 35 of the lever arms 34 in Figures 1 and 2. Preferably, there are straps 50 connected with these same pins 48 which lie parallel and against the face of the lever arms 36 and they are provided with laterally extending pins 5| which are adapted to abut against one edge of each of the lever arms 36 when the spring frame is in the position shown in Figures 1 and 2, to limit the relative rocking motion of the lever arms 36 and 34 to about the position shown in these figures. In other words, they prevent the joined ends of the lever arms 36, 34 fro-m moving upwardly in Figure 2, and thus allowing the spring frame to drop.
Operation In order to attach the present device to a bed and its spring frame, it is only necessary to apply the brackets shown in Figures 1 to 7 to the side beams of the bed frame by disposing them upon the side beams in the manner shown in the drawings, where they will engage and rest without any bolts or screws for holding them in place, although such may be used if desired. If there are any cross slats or supports on the bed these may be removed if desired to leave the entire space within the bed structure free and open.
The clamps 3! are attached to the cross bars IQ of the spring frame. One of the side rails of the spring frame is presented to the bracket l8 so that the horizontal wall 2| of the side rail enters the slot 20 of the bracket member I8 while the locking member 28 is'turned up, whereupon this locking member is turned down to hold the member 7 locked to the bracket member It.
When the bed is in use or in condition for use, the parts will be in the condition shown in Figure 4 where one side of the spring frame is supported by the brackets [3 upon one of the side beams of the bed frame and the other bar 6 of the spring frame rests upon the projecting supports 43 of the right hand bracket 39. The
lever arms 34, 35 with their springs are all folded up close to the under side of the spring frame and during this time the springs 41 are drawn out or a under tension, and the springs 44 are also drawn out and under tension. No part of the present device need be connected with any cross members of the bed frame if there are any nor with the head board or foot board structures.
To operate the device to give access for cleaning the floor below the bed, or for cleaning the bed springs, the operator may grasp the spring frame at the right side of the bed, as shown in Figure 4, or the front side as shown in Figure 1, and lift this side of the spring frame until the parts are in the position shown in Figures 1 and 2, whereupon complete access may be had to the floor below the bed as well as to the various parts of the bed springs and frame for cleaning purposes. The spring frame and mattress may also be elevated in this manner to allow better circulation of air around the springs and mattress. Before raising the spring frame the abutment arms 39 may be swung from the horizontal into the vertical position so that when the spring frame is elevated to the inclined position one side of the mattress may rest against these arms which will prevent it from sliding off the spring frame. In the operation of raising the spring frame in the manner described, the operator does springs 44 and 47.
ing pressure upon the rod 46 and therefore upon the lever arms 36 which pressure tends to move the spring frame into the position shown in Figures 1 and 2, but their strength is not sufficient to completely lift the spring frame and mattress as otherwise it would be necessary to lock the spring frame in lowered position.
The springs 41 are also exerting a pulling tension upon the pins 48 which are connected with the arms 49 of the levers 34. While the bed spring and mattress are in the lowered position shown in Figure 4 the springs 4'! have very little effect on the tendency to lift the spring frame and mattress because these springs are almost in alignment with the lever arms 34. However, as soon as the operator starts to lift one side of the spring frame the levers 34 pivot about the pins 35, whereupon the springs 41 exert an increasing pull upon the lever arms 34 and this action is added to the action of the springs 44 and their combined strength may be so designed as to completely lift the spring frame and mattress once the pivotal motion thereof is started by the operator, so that the latter may merely initiate the lifting operation and the remainder of the movement may be carried out entirely by the When the parts reach the position shown in Figures 1 and 2 the pins 5! will strike against the under edges of the lever arms 36 and thus stop the rocking motion of the lever arms 36, 34 after the arms 49 of the latter have passed one side of the pivotal points 35 thereby limiting or setting the positions of the several lever arms so that the spring frame and mattress will remain in the position shown in Figures 1 and 2 while the floor is being cleaned, or while the springs and their frame are being cleaned.
To lower the device back into operative position, shown in Figure 1, the operator need simply press the arms 49 backwardly or press the lever arms 36 backwardly, and pulling downwardly on the right hand side of the spring frame until the lever arms 49 have swung to the other side of the pivots 35 to break the joint, whereupon the operator merely continues to press downwardly on the right side of thespring frame in Figure 2, until the parts have been returned to the position shown in Figure 4. The pressure required on the spring frame to lower the parts to the position shown in Figure 4 is very light as it is merely the difference between the raising effect of the several springs and the weight of the spring frame and mattress. a
During the pivotal motion of the spring frame it swings about the pins IT on the brackets l3. By having the supports 43 extend inwardly some distance from the brackets 39 the spring frame will rest upon these supports even though its width does not correspond exactly with the space between the two beams 3, 4. In other words, the spring frame does not have to correspond exactly with the spacing of the side beams of the bed rame. V
The device may be readily detached from the bed by simply lifting the brackets is, 39 off the bed frame either in conjunction with the spring frame or the brackets may be detached from the spring frame and the bar of the spring frame may be detached from the brackets.
In Figures 8 and 9 I have shown a modification of the bracket devices in order to adapt the present invention to bed frames of metal construction. In FigureS I have shown an angle metal members of a metal bed frame and corresponds in position and function with the wooden beam 3 of the first described form. The bracket member 54 is provided with a slot 55 to receive edgewise therein the horizontal web 56 of this angle metal beam and this bracket is preferably provided with a laterally extending member 51 which engages the under surface of the web 56 of the .bed beam and with another laterally extending member 58 engaging thetop surface of the web 56. To this latter member there is pivoted at 59 a locking member 69 which when in raised position permits the web 56 to enter the slot 55 and which, when in lowered position, as in Figure 8, engages the left hand surface of the vertical web GI and locks the bed frame member to the bracket 54. The bracket member 62 which is pivoted to the bracket member54 on the stud 63 corre sponds with the bracket I 8 shown in Figure 6 and previously described, and the parts connected therewith, such as the swinging arm 39 for holding the mattress and the pivotal locking member 28 are all the same as in Figure 6.
In Figure 9 I have shown a type of bracket to replace the bracket shown at the right in Figure 4 to adapt it for a bed frame of metal construction. In this view the bracket 64 is provided with a slot 65 to receive the horizontal web 66 of the right hand angular bed frame member. This bracket has a lateral projection 61 adapted to engage the under surface of the horizontal web 66 and a lateral web 68 engaging the upper surface of this same horizontal web. To the latter there is pivotally connected by the pin 69 the locking member 10 which when in lowered position as shown in Figure 9, engages the outer surface of the vertical web H and locks the bracket 64 upon the beam. There is a downward projection 12 extending from the bracket portion 64 and the lever arm 36 is pivoted to this downwardly extending projection on the pin 13 in the same manner that the lever arm 36 is connected to the member 43 in Figures 1, 2 and 4. The brackets shown in Figures 8. and 9 adapt the device to a bed frame of metal construction and embody the same principles as are disclosed in the first described form of the invention.
In Figure 10 I have shown a method of attaching the lifting device to a bed frame, the side beams of which are of tubular form. In this form I have shown the tubular member 14 as the longitudinal beam of a bed frame. There are two members 15, I6 pivotally connected with each other at 11 each having an arcuate portion partly surrounding the beam 14 and adapted to be clamped upon this beam by the bolt 18 passing through cars 19 extending laterally from each of the arcuate members. The straight or stem portions 80 projecting from each of the arcuate members 15, I6 lie face to face against each other and they overlap each other. One of these projections is carried out to form an extension 8| which has a pin 82 on which either the bracket shown in Figures 5 and 6 or the brackets shown in Figure 8 is attached. In other respects the construction may correspond with that shown in Figures 1, 2 and 4.
In Figure 11 I have shown a modified form of bracket for attaching the brackets of the lifting device to the rail strip ordinarily present on wooden bed frames, instead of being mounted directly upon the beam of the bed frame. At 83 I have shown one of the rail strips which is attached to the bottom and inner side of the beam 84 of the bed frame. The bracket 85 in this construction consists of a web 86 resting upon the rail strip 83 the web 81 extending downwardly inside the rail strip, and a horizontal web 88- extending under the rail strip. Thumb screws 89 threaded in this lower web 88 are adapted to be screwed up against the under side of the rail strip 83 to hold the clamping member thereon. The bracket 90 has a bottom end 9| extending at right angles thereto and riveted to the upper web of the clamp 85. This bracket 90 extends upwardly along the inner side of the beam 84 and its top end is provided with the rivet 92 on which the bracket 93 is pivotally mounted. This latter bracket 93 and the parts carried by it correspond in construction and function with the bracket l8 shown in Figure 3.
From the above it will be apparent that I have provided a spring lifting device which gives complete access to the floor below the bed for cleaning, as well as full access to the spring for cleaning. The device is simple and effective and while it may be factory built on the spring frame, it is also adapted to be applied to the spring frame and bed frame by the user and without the use of tools. The device in no way injures nor mars the bed frame. It also permits all cross members of the bed frame intermediate the head and foot boards to be removed if desired. The device requires no attachment to either the head board or the foot board.
