Claims.
This invention relates to he u devices 1' the type which may be removably attached to beds, so that a person resting upon the mattress of said bed may receive therapeutic treatments.
Various devices have been provided for imparting therapeutic, gyratory oscillations to a person resting or reposing upon a bed, but such devices have usually embodied a construction which was a permanent part of said bed or which require a special construction of bed or mattress.
An object of this invention is to provide an improved therapeutic device which may be attached to a standard bed frame in a position over a. mattress, so that a person may, when reposing on said mattress and abutting said device, receive directly the benefits of said therapeutic device.
Another object of the invention is to provide an improved therapeutic device which may be removably attached to the frame'of a bed; which may be adjusted to different distances from the end frame of the bed; which will impart therapeu tic, gyratory movements to a person reposin on the mattress and abutting the device; with which a person may press against said siderable extent without displacing said device; which will not cause objectionable or noisy movements of said bed, and which when not in use may be shifted into a compact position against an end frame of the bed, and which will be relatively simple, compact, effective, quiet, efficient and inexpensive. I I
Other objects and advantages will be apparent from the following description of an embodiment of the invention and the'novel features will be particularly pointed out hereinafter in connection with the appended claims.
In said drawings:
Fig. 1 is a plan of one end portionof a bed to which a therapeutic device constructed in accordance with this invention has been applied;
Fig. 2 is a side elevation of the same with a portion of the bed frame broken away;
Fig. 3 is a sectional elevation through a housing in which the source of gyratory movement is mounted and showing the mounting between the motor and the housing, the section being taken approximately along the line 33 of Fig. 1;
device to a con- Referring first to Figs. 1 and 2, the improved,
device is shown as applied to a bed having an end post or frame I with a plurality of upright bars 2, and a mattress 3 at one side of the end frame. The bed is of any suitable construction, and only that portion thereof has been shown which is necessary in explaining the use of this improved device. A pair of clamping plates 4 and 5 are disposed on opposite sides of a plurality of the bars or upright rods 2, and are clampedthereto by a bolt 6 which passes through the plates and carries a wing nut I by which the plates may be drawn together in firmly clamped relation to the upright rods 2. The plates 4 and 5 have facings 8 of rubber or other resilient means to prevent marring of the rods 2 when the plates are clamped thereto.
The plate 4, which is secured against the inside face of the end frame I, is provided adjacent opposite side edgesthereof with angle members 9 and all which provide ears extending from the same face of the plate 4. Links II and I2 are hinged to the ears 9 and I0 respectively by pins I3. A link I4 is hinged by a pin I5 to the free end'of the link I2, and at its other end by a pin I6 to an ear I"! extending from a plate I8. The free end of the link I I is similarly hinged by a pin I9 to one end of a link 20, and the other end of the link 20 is pivotally connected by a pin 2| to an car 22 also carried by the plate I8 adjacent the opposite side edge from the ear I1. The pin I9 is a bolt with a wing nut 23, so that the links II and 20 may be frictionally clamped together by tightening the wing nut 23 when relative movement of the links is not desired. A tie link 24 hinged at one end upon the pin i5 that connects the links I2 and I 4, is provided with an elongated slot 25 through which the shank of the bolt I9 extends. A washer 26 beneath the wingnut 23 engages against the face of the tie link 24.
By tightening the wing nut 23, the link 24 is tightly clamped to the links II and 20, which unites the links H, l2, I4 and 20 and plates 4 and Fig. 4 is a sectional plan through part of the housing, at right angles to the sectional plane of Fig. 3, to show details of the mounting of the motor in the housing; and I Fig. 5 is a diagram illustrating the principle by agyratory motion in a which the motor creates closed loop path,
I I8, as a rigid frame. By loosening the nut 23, the 7 plate I8 may be moved toward or from the plate 4 over a considerable range, so that the plate I8 may be positioned at any of a plurality of different distances from the end frame of the bed and above the mattress 3. The plate I8 may be secured in any of such of the nut 23. The plate I8 is parallel to the plate 4, and in a plane normal to the upper surface of the mattress 3.
Cemented or otherwise secured to the outer face of plate I8 is an interponent mass or body positions by a tightening 21 of soft, resilient material, preferably sponge rubber, and cemented or otherwise secured against the exposed face of this body 21 is an outside face 28 of the housing 29, so that the housing is secured to the plate l8 solely through the resilient body 21. There is no other connecting means between the housing and the plate l8, and this mass 21 of soft, resilient material, such as sponge rubber, need not be continuous over the entire face of the plate, i8, but may, for example, be a band of this material extending around the periphery of the plate IS. While the mass 21 could extend over the entire face of the plate 18, this is unnecessary, since a marginal band only of this material will anchor the housing to the vantageously be from one-half to oneinchin thickness, and two or more inches in width from the marginal edge.
The housing 29 may bea box formed of any suitable material, such as wood, metal or plastic material, and its interiorisidivided by a partition 39, see Fig. 3, into two chambers 3| and 32. This partition 30 is horizontal and generally parallel to theupper surface of the mattress 3 and nor,- mal to the planeof a face of the plate 8. Within the chamber or compartment 32 or the housing 29 is a motor 33 or other device for causing gyratory movements of small amplitude and high frequency of the housing. A small, standard electric motor is very suitable for this purpose, and it has an armature shaft or rotor 34 extending from both ends of the housing of'the motor, horizontally and parallel to the upper-face of the mattress 3. Each end of the shaft 34 carries a fan 35, and both fans cause movement of air in the same direction in the chamber 32. The end walls of the housing are provided with apertures 36 and 31 by which air may bemoved through the housing from end to end under the propelling action of the fans 35. p 7
The shaft 34 of the motor is provided with an axial unbalance on one side only thereof, so that as the shaft rotates, this unbalance will form a centrifugal force tending to pull the motor shaft in a closedloop, gyratory path with an amplitude depending upon the extent of the unbalance. In this particular example, the blades of the fan are mounted fin-blocks 38 which are eccentric to the shaft 3'4 and secured thereon by screws 29. The screws also 'carry weights 40 which give added unbalance to the blocks 33 and increase the axial unbalance of the rotor to the I desired extent'. The frame of the motor, of cours'e,has openings at its ends and around its periphery through which air may pass in order to remove heat formed during the operation of the motor. Also arranged around the periphery of the frame of the motor are a plurality of cushions or resilient elements ii, there being preferably two of such cushions on each side of the motor frame, and engaging the adjacent wall of the chamber 32.
These cushions or elements 6! are of soft, resilient material, such as sponge or gum rubber, and I have found that soft, gum rubber tubing is very suitable for this purpose. Such tubing may be cut into short lengths and the lengths split in halves. The flat faces at the splits abut against the faces of the motor frame, with the convex surfaces of the tube sections abutting against the walls of the chamber 32. The walls 32 may have recesses or grooves 42 which receive the convex surfaces of cushions or elements The distance between opposite walls of the chamber 32 is such that when the motor is placed in the chamber, the cushions or elements M will be under substantial compression, and because they are cemented or secured to the motor, will, through their engagement with the grooves 32, limit displacement of the motor in the chamber 32.
The cushions or elements serve as the sole sup port between the motor and the walls of the chamber 32, and are, in effect, a floating support for the motor. The motor is, of course, of less lateral dimensions than the distance between the opposite walls of the chamber 32, so that there will be no direct contact between the motor. and any part of the housing 29.
Disposed. within the chamber 3! of the bone-- ing 29 is rheostat 43 with an operating stem or shaft i iextending outwardly through an aperture 55 in the housing and carrying at its outer end an operating button 36. ()ne of the lead wires 47 from the motor 33, isconnected to one terminal d3 of the rheostat 43, and the other lead wire 49 of the motor extends outwardly through a tubular bushing 50 provided in an end wall of the housing 29. The other terminal of the rheostat 43 is connected to a wire 52 which also extends exteriorly of the housing 29 through bushing 53. By connecting the wires 39 and 52.
to a source of current, the motor 33 will be operated at a speed dependent upon the adjus ment of the rheostat 43 through manipulation of the button 46. The partition 3%] may have spaced apertures 53 and 54 therein, so that some of the air entering the chamber 32 may also pass through chamber 3] and remove any excess heat from the rheostat43. 7
Referring now to the diagram of Fig. 5, the nature of the movement of the axially unbalanced motor shaft will be briefly explained. The unbalance of the shaftis shown by the weight ref V ence characters 38 40, and when such weight is rotated with the shaft in the direction of the arrow A through operation of the motor 33, centrifugal forces will becreated which are repre sentedby the arrow C. The centrifugal forces Y tend topull the shaft 34 in a closed circular path represented by the arrow B, which has a center, of curvature that is eccentric to the axis of the shaft 34. This unbalance of weight 38-4 Ei therefore tends to move or drag the motor bodily asa unit in a circular, gyratory, closed loop movement having an amplitude or pathof movement depending upon the amount of'unbalance and speed of rotation.
Since the motor is spaced from the wallsof the chamber 32, this centrifugalforce tending to drag the motor in this closed loop path isresisted approximately evenly in all directions by the cushion or elements 4!, and it hasbe en found that under such circumstances the bearings of the motor will not disintegrate, due to the unbalance. however, acts through the cushions or elements 4| upon the housing 23 and tends to cause similar gyratory movements thereof. Since the housing 29 is supported entirely or largely through the sponge rubber mass 2! on plate IS, the housing 29 may move in this gyratory closed path. While some of this movement of the housing 29- may be i transmitted through the mass 2'! to plate I8 and thence to the end frame I of the bed, the trahsmission to the end frame I will not be enough to cause objectionable noise or vibration of the frame of; the bed. Such movement as is trans mitted to the bed frame will be imparted to the This movement of the motor,
4 ,43 3 and through it to a person reposing mattress thereon. I
In the use of a device of this type, and with the device assembled in the manner shown in Figs. 1 and 2, themotor is placed in operation and a person then reposes upon the mattress 3 of the bed in contact with the exposed face 53 of the housing 29. For example, one may lie or sit on the bed. with the bottoms of the feet resting against the upright face 53 of the housing 29, and then this gyratory movement of the housing 29 will be imparted to the bottoms f the feet. The result is something like a massage movement thattend to increase the circulation of the blood through the feet, relax the muscles of the feet and legs, and generally improve the health and condition of the person undergoing the treatment. The housing 29 may be adjusted back and forth toward and from the end frame of the bed so as to be most convenient for persons of different heights, or in different positions on the mattress.
In place of this manner of treatment of the feet, one may sit upon the mattress with his back abutting against the upright face 53 of the housing 29, and in such a case, the therapeutic action of the housing through its contact with the back of the patient will create an improved circulation of the blood in the back, will tend to relax the back muscles, and will generally improve the comfort and health of the patient. There are various other ways in which the device may be used advantageously, but the two examples given illustrate some of the uses to which it can be put. It will be understood that while the gyratory movements of the housing will be transmitted directly to the body of the patient by contact of the patient with the housing, some of these gyrations or movements of the housing may also be transmitted through the frame of the bed to the mattress, and thus to a much lesser extent to the entire body of the patient reposing on the mattress.
It will be understood that various changes in the details, materials and arrangement of parts, which have been herein described and illustrated in order to explain the nature of the invention, may be made by those skilled in the art within the principle and scope of the invention as expressed in the appended claims.
