(Cl. 12S- 41) 3 Claims.
My invention relates to electro-therapeutic and mechanically vibratory appliance for the feet for beneficial applications thereto and more especially to a vibrator embodying a movable applicator element and electrically operated means for efecting vibration of the applicator element.
Electrically driven vibrators have long been in demonstrable and practical use as beneficial in massaging of skin tissues and corrective muscle application and treatment, and the especial objects of my invention are to introduce a technique in the treatment of foot troubles, and to promote foot health and comfort.
The principles of my improved vibrator recognizes the fact that common foot troubles are the results of poorly tted shoes, improper Weight distribution, dormant foot muscles and poor circulation. To correct these common causes of foot disorders, my invention provides a corrective therapeutic action to exercise and strengthen muscles and ligaments, stimulate normal circulation, build up the arches to accept and distribute body Weight as nature designed.
My invention provides ve therapeutic actions, namely: controlled vibration, soothing oscillation, gentle percussion, and penetrating healing electromagnetic Waves of the infra-red ray type.
The object of my invention is to provide a therapeutic and corrective device for the human feet characterized by the provision of co-operating vibrated and unvibrated treatment surfaces, and by an improved construction for driving the vibrated surface.
Another object of my invention is to provide a corrective device for the feet which presents a smooth convex treatment surface of extended area, the control portion thereof being adapted for vibrating movement with respect to the outer portion thereof, which outer portion is nonvibratory.
Another object of my invention is to provide an electrically driven vibrator which is so formed as to render it especially applicable for use in treatment of both feet simultaneously, or one foot independently; and for these purposes having its parts so formed and arranged that the device may be supported on a oor with the vibrating elements so positioned that the soles of the feet may be readily and comfortably rested thereon for the operative treatment.
A still further object of my invention is to provide a corrective vibrator by which the feet can be simultaneously massaged, and treated with heat rays or other forms of health giving rays,
in conjunction with or independently of the vibrating action.
A still further object is to provide a duplex therapeutic vibrator equipped with (zo-operating vibrated and unvibrated treatment surfaces in which the vibrated treatment surfaces have components of vibration normal to said surfaces, and components of vibration that Will admit 0f soothing oscillation, gentle percussion, soothing warmth and controlled action.
A further object is to provide a duplex corrective vibrating device which may be placed in a position to accommodate the soles of the feet in such a manner that the portion of the feet undergoing treatment may be pressed against the vibrated portions of the treatment surfaces with variability of pressures controlled by the patient.
A further object is the provision `of a device for the corrective treatment of the feet which embodies vibrators having controlled oscillations, gentle percussion, and that contain electrical elements for producing health giving light rays.
. A further object is to provide a foot corrective device in which the vibrator parts thereof are of extremely simplified and durable construction, and which embody electro-magnets as the vibrating means, and armatures thereof being controllable by means adjustable to vary the amplitude of their vibration.
A still further object is to provide construction in a duplex vibrator whereby parts may be economically formed and readily assembled.
It is also the object of my invention to provide certain and definite improvements over my Letters Patent Number 2,067,979 dated January 19, 1937, and my pending application Serial Number 112,187 filed November 23, 1936.
With the foregoing objects in View, together with such other objects and advantages as may appear, the invention resides in the combination, construction and arrangement of parts hereinafter described and claimed.
Reference is had to the accompanying drawings in which similar reference characters indi cate similar parts wherever they may occur.
In the drawings which form a part hereof:
Figure l is a vertical longitudinal section of my improved electro-therapeutic and mechanically vibratory appliance for the feet, taken on the line I-I of Fig. 2.
Figure 2 is a top plan view of the base per se and showing the operative mechanisms mounted thereon.
Figure 3 is an enlarged vertical section taken on the line 3-3 of Figure 4.
Figure 4 is an enlarged end elevation, partly in section, of one of the vibrator mechanisms per se; and
Figure 5 is a diagram of the electric wiring.
Referring to Figure 1, generally designates the duplex casing having spaced circular openings 23 and 24 in its top wall and convexed or dome-shaped vibrator elements or applicators 25 and 26 operatively mounted thereon.
The applicators 25 and 26 are removably mounted on screw studs 2'1 and 28 which are secured to lugs 29 and 3D secured to magnetic armature bars 3| and 32. Disposed in square shaped openings in base 33 are secondary frames 34 and 35 held in place to base 33 by screw lugs 36 and 3l. Interposed between secondary frames 34 and 35 are a series of posts 38 and 39, shown as four in number to each of the secondary frames 34 and 35 and arranged at the four corners of a square.
The coil springs and 4| are vertically circumferentially affixed to posts 38 and 33'. The lower end portions of coil springs 4|) and 4| are seated in recesses 42 and 43 formed in secondary frames 34 and 35, and the upper ends of coil springs 4i) and 4| seat in recesses formed in the undersides of screws 44 and 45, aiiixed to posts 38 and 39.
Armature bars 3| and 32 are carried by U-shaped support members 45 and 4l secured to cnil springs 46 and 4| by collars as shown at 48 and 43. Arranged within the space bounded by secondary frames 34 and 35 are electro magnets and 5| extending vertically diametrically of the base of secondary frames 34 and 35.
Armature bars 3| and 32 spaced in close proximity to electro magnets 55 and 5| diametrically above thereof are adapted to be attracted by the latter upon the energization of electro magnets 55 and 5| against the opposition of coil 1ings 4U and 4| in such position as to limit the vibrating movements of armature bars 3| and 32 with respect to the electro magnets 5D and 5|, and therefore insure the quiet operation of the device.
Arranged interiorly of the applicators 25 and 25 are electrical heat elements 52 and 53 for supplying health giving warmth to the feet resting upon the applicators. The electrical elements are comprised of coils of chromium alloy wire or any other material having a relatively high temperature co-eiiicient.
Referring to Figure 1, my duplex foot masand therapeutic device is wired with electro magnets 50 and 5| which are connected in iseries with a tapped inductance or choke coil which is provided with a multiple tap switch 54. This provides a selection of intensity of vibration by variation of amount of induction in series with the electro magnets 50 and 5|. lThe heating elements 52 and 53 are connected in series with a toggle switch 55 for manual control from the top of the machine.
The toggle switch 55 is wired in shunt to the terminals of the heat elements 52 and 53, and
the coils of the electro magnets 5D and 5|. As here shown multiple tap switch 54 includes a stationary contact member 5l' to which is connected an electrical conductor 5i' of the alterhating current supply.
The multiple tap switch 54 also embodies 3 terminal switch arms 58, 59 and 60, otherwise designated as low, medium and high, which said terminal switch arms are connected in series with choke or inductance coil 6|. The
choke or inductance coil 6| comprises the tapped winding 52 with the conventional laminated core 63. The core 63 is preferably secured to base 33 through the agency of bolts 64 extending transversely through the core 63 at the ends thereof and respectively engaging a suitable attachment shoulder 65 forming an integral part of the iron base 33 and acts to complete the magnetic circuit of the coil 63. The shoulder 65 is centrally disposed said base between electro magnets 50 and 5| and the bolts 64 serve to both compress the core body upon itself and also to secure the core 63 to the shoulder 65.
Referring to Figure 4 I have shown diagrammatically the necessary circuits for supplying current to energize the electro magnets 50 and 5I for affecting operation of vibrating applicators 25 and 26, and heating the elements 52 and 53 for producing heat.
Alternating current supply lines 55 and 56 are adapted to be connected to stationary contact member 57 and coil winding of electro magnet 55 and from these contacts wires 66 and 57 and 5l leads to contacts 55 which is the toggle switch, and heat elements 52 and 53, and the coil winding of electro magnet 5|.
From stationary Contact 51 wire 5l contacts wire 66 thus connecting the circuit from supply lines 55 and 56 supplying current to electro magnets 5G and 5| and the heating elements 52, 53. In the wire 68 is interposed choke or inductance coil and also multiple tap switch 54. Wires 55, 63 and 'l0 are adapted to be connected to the switch arms 58, 59 and 6G, respectively, and the wires 5? and 66 being connected to the terminals of the heating elements 52 and 53 and the terminals of the coils of electro magnets 5U and 5| so that the inductance coil 52 of the choke coil 6|, which serves to supply current to the heating elements 52 and 53, while the multiple tap switch 54 permits regulating the power and rapidity of the vibrating elements 25 and 26 to meet the requirements of a particular treatment.
In the operation of my foot massaging and therapeutic device when it is desired to actuate the applicators 25 and 26 the multiple tap switch 54 is rotated to direct alternating electrical current through the electro magnets 50 and 5| intermittently energizing the electro magnets so as to cause the armature bars 3| and 32 to magnetically reciprocate with rapid impulses in one direction in opposition to the coil springs 43 and 4|, and in the opposite direction under the resiliency of coil springs 40 and 4| in the intervals between impulses of the electro magnets 50 and 5|. The power and rapidity of vibrations may he increased or decreased at the will of the operator hy positioning the multiple tap switch 54 to direct current through the terminal switch arms 58, 59 and 60, otherwise designated as low, medium and high In the treatment of the feet the device is preferably upon the floor to give the maximum of rigidity, and the soles of the feet are rested on the applicators 25 and 26.
When itis desired to effect the application of heat, the toggle switch 55 is positioned to direct current through the heating elements 52 and 53.
Heat and vibration may be affected concurrently by positioning the multiple tap switch 54 and the toggle` switch 55 as indicated and shown.
Many other modifications and changes in detail will readily occur without departing from the spirit and scope of my invention as dened in the appended claims for which I desire to secure by Letters Patent.
