' 9 Claims. (Cl. 12833) This invention relates to vibrating devices and more particularly to an improved portable vibrating device adapted to be readily and easily attached to or detached from a bed.

The invention comprehends a device including a relatively thin flat flexible horizontal member, adapted for insertion between the mattress and spring of a bed, and a vertical member connected to one end of the horizontal member and adapted to be detachably clamped to a side or end rail element of the bed frame.

Although the basic concept of providing a portable at: tachment for creating vibrations in a bed or other related article of furniture is not new, my invention embodies several novel features which, to my knowledge, have never heretofore been employed in prior art devices of this type.

In some of the known bed vibrating devices, vibrating mechanisms are designed to be mounted on some portion of a bed frame and are operable to set up primary vibrations directly in the bed frame itself, with secondary vibrations being transmitted to the bed spring or mattress only indirectly through the frame. In other devices the vibrating mechanisms are attached directly to the bed spring or mattress of a bed.

There are obvious disadvantages to both types of arrangements. In the first type of arrangement, the vibrations in the bed frame are or far greater magnitude than is either necessary or desirable. Naturally, when a bed frame vibrates appreciably, a considerable amount of vibration will be transmitted to the floor of the room in which the bed is located and also to the ceiling and/or walls of adjoining rooms of the building.

In the second type of arrangement, there are at least three important disadvantages: one is that in the absence of a positive means to anchor the device to the bed frame, there is a tendency for the device to shift about relative to the mattress or spring, which of course can cause damage to the mattress or .spring and to the bedding on the mattress. Also, appreciable damage to furniture in the room or injury to an occupant of the room or bed could result if the movement of the device becomes so great as to cause the device to become detached from the spring or mattress; a second disadvantage is the amount of undesirable noise which can be caused by a device which protrudes from a bed without any positive anchoring means other than the weight of the mattress and the person on the mattress; and a third disadvantage is the fact that a device which has a portion projecting outwardly from the bed to which it is applied constitutes a definite hazard or obstacle capable of causing injury to a person coming into contact with the device or damage to clothing of the person.

It is therefore a primary object of this invention to provide an improved portable bed vibrating device comprising one member abuttably engaging the spring and/ or mattress and another member attached to the bed frame.

Another object of the invention is the provision of a Patented Sept. 20, 1960 2 vibrating device including resilient means interposed be tween one portion of the device and the bed frame.

Yet another object of the invention is the provision of a vibrating device wherein the portion thereof which is connected to the bed frame is vertically adjustable to permit its use with beds of various types and sizes.

Still another object of the invention is to provide a vibrating device wherein the mechanical vibrating means is entirely disposed under the mattress with no portions protruding outwardly from the bed any substantial dist-ance.

These and other objects of the invention will be ap parent from an examination of the following description and drawings, wherein:

Figure 1 is a fragmentary end view of a bed to which has been applied a vibrating device embodying features of my invention with certain portions of the device being shown in vertical section, and I Figures 2 and 3 are fragmentary side elevational views of the device illustrated in Figure 1, as seen from the outboard and inboard sides, respectively.

It will be understood that certain elements have been intentionally omitted from certain views where they are better illustrated in other views.

Referring now to the drawings for a better understanding of the invention, it will be seen that the vibrating device embodying features of my invention is shown as applied to a bed having a mattress A and spring B supported on a frame C which comprises side rails D, end rails E, and legs F. Only one side rail, end rail, and leg are shown in the drawings as the bed may be of conventional construction.

As best seen in Figure l, the device comprises a relatively thin flat slightly resilient horizontal member or plate 10, adapted for insertion between mattress A and spring B of the bed, and a vertical member 12 secured to one end of horizontal member 10 and adapted to be detachably mounted on either side rail D, as shown in Figure l, or on end rail E, not shown, of the bed in a manner hereinafter described.

Vertical member 12 preferably comprises a pair of adjustably interconnected parallel upper and

lower elements

14 and 16, respectively.

Horizontal member 10 is preferably of a suflicient length to extend a substantial portion of the distance across or lengthwise of the bed; however, inasmuch as

members

10 and 12 may be detachably interconnected, the device may be provided with separate horizontal members of different lengths to accommodate the use of the device with beds of different sizes. Member '10 may be constructed of various materials, although a preferred material is fiberboard, which has the desired resilient characteristics and which presents on one side thereof a rough surface 18 operable to prevent slippage or relative sliding movement between the horizontal member and the mattress and/ or spring.

At one end thereof, horizontal member 10 may be detach-ably secured, in any desired manner, to a horizontal flange 22 formed integrally with and extending inwardly from the upper edge of vertical member upper element 14.

Both the upper 14 and lower 16 elements of vertical member 12 are relatively thin fiat semi-resilient plates, preferably formed of sheet metal. The elements are disposed closely adjacent each other with the lowerelement being positioned inwardly of the upper element between the upper element and the side rail D of the bed. Both

elements

14 and 16 may be provided with a plurality of complementary formed transversely spaced vertically extending ribs 24 to add rigidity to the structure. The ribs may be formed integrally with the elements or they may be permanently affixed to the outer side of element a distance sutficient to locate the lower element in 7 horizontal alignment with thesaid rail D of the bed.

Thus, it will be apparent that this adjustable feature permits the use or the devicewith beds-of various types having diiferent distances between the upper surface of the spring and the side rail.

, Mounted on the inner side of element 16 adjacent the lower end thereof is a small preferably electric motor 28 with a shaft 30 having aweight 32 eccentrically disposed thereon and rigidly secured to the end thereof. Forpurposes of safety, the endof the shaft and the eccentric weight may be enclosed by a housing or cover 34.

On its inner side, element 16-may be provided with one or more relatively thin flat resilient pads or cushions 36 permanently aflixed thereto in'any desired manner as by bonding.

' Additionally, element 16 maybe provided witha pair of clamp brackets 38 to facilitate-clamping of the device to a side rail of the bed. The clamps may be permanently attached toelement 16 in any desired manner,- by welding, not shown. Threadably received within each bracket 38 isa clamp screw 40 having on one end :thereof a swivel pad 42' engageable with side rail D. j Inorder to assemble the device, after member :10 has been secured to flange 22 of element 14 of member 12, 7 member 10 is inserted between the upper surface of spring B and the lower surface of mattress A' and the wing nuts of assemblies 26 are loosened to permit the adjustment of element 16 to the proper height. The Wing nuts are then secured and the entire device is pushed toward the center of the bed .until resilient pad 36 is in contact with the outersurface :of bed side rail D. Clamp screws 40 are tion to a bed having a frame with end and side rails and a mattress and spring supported on the frame, comprising in combination: a horizontally disposed relatively thin flat flexible member adapted tobe interposed between the spring and mattress; a vertical member connected at its upper end to the horizontal member and adapted to be detachably connected to one of the rails of the frame; means to detachably conuectthevertical member to said one rail; resilient means interposed between the vertical member and said. one rail; and means carried by the vertical member operable to vibrate said device and thereby cause said mattress to vibrate. a

'3. A portable vibrating device fordetachable connection to a bed having a frame with end and side rails and a mattress and spring supported on the frame, comprising in combination: a horizontally disposed relatively thin flat flexible member adapted to be interposed between the spring and mattress; a vertical member comprising a pair of parallel upper and lower plate elements interconnected to permit adjustable vertical movement therebetween, the upper elementbeing disposed adjacent the lower element and being connected to the {horizontal member, the lower element including means to detachably connect said vertical memb'er'to one ofthe rails ,of the frame; and means carried by said lower element operable to vibrate said device andthereby cause said mattress to vibrate. V

4. A portable vibrating device according to claim 2, wherein said vibrating means is disposed entirely on the inboard side of the vertical member and entirely under the horizontal member. v

5; A portablevibrating device according to'claimfZ, wherein the means to connect said vertical memberto said one rail includes clamp means permanently attached to the vertical member for detachable connection to said 7 one rail.

6. Aportable vibrating device for a bed having a frame with end and side rails and a spring and. mattress supported on the frame, comprising in combination: a relathen tightened-to secure the vertical member of the device to' the bed.

The motor is then'energized and its vibration, caused by the eccentric weight 32 on shaft 30, causes

elements

14 and 16 of vertical member 12 to vibrate and in turn vibrate horizontal member 10 which transmits "the Vjbl'fl'.

' tory motion to the springs and/or mattress.

If desired, the outwardly facing side of clamp screw pad 42 'may, be. provided .with a small resilient cushion (not shown) for interposition between the-pad and the inner'side of rail 'D' to absolutely minimize the amount of vibratory motion which is transmitted to bed frame C l from element 16 of member 12 of the device.
