Martha A; Buss, Syrause, N; Y; Application May 18, 1948, Serial No. 27,73?
This invention relates to a therapeutic Vibrator and it consists in the constructions, arrangements and combinations herein described and claimed.
It is a particular object of the invention to provide an unbalanced rotor for a vibrator device so as to provide an uneven and lasting shock impulse to the portion of a body undergoing treatment, the impulse being diverted to greater areas of the body.
It is also an object of the invention to provide a vibrator rotor wherein a pair of weight members are disposed at rights to each other, of equal size and of the same cross sectional area whereby under rotation an even force will be transmitted to that portion of the body undergoing treatment.
It is a still further object of the invention to provide a novel construction of housing for a vibrator unit adapting the device to the positioned upon practically all portions of the body of a person and being constructed of a material which will readily transmit the vibratory impulses to the body.
Additional objects, advantages and features of invention will be apparent from the following description, considered in conjunction with the accompanying drawing, wherein Figure 1 is a perspective view of a vibrator constructed in accordance with the invention.
Figure 2 is an end elevation of the vibratorj-with a portion of the wall broken away, illustrating the mounting of the vibrating unit.
Figure 3 is an end View of the vibrator with a portion of the wall broken away, illustrating the relation of the rotor with respect to the vibrator unit.
Figure 4 is a perspective view of the rotor detached from the vibrator unit.
Figure 5 is a rear elevation, and
Figure 6 is a side elevation of the rotor.
There is illustrated a vibrator generally indicated by the reference character l0, which as shown in Figure 2, comprises an upright resonant wooden wall ll upon one face of which there is mounted a vibrator unit [2. In the present instance, a pair of headed bolts 13 are secured in the wall 11 projecting therethrough and rigidly engaged in the frame of the vibrator unit.
To respective end edges of the wall I I resonant wooden side walls 14 are secured as at 15, the lower edges of these walls having a concave contour indicated at 16, while the upper edges of the walls are of convex shape as at 11. A resonant wooden top wall 18 is secured between respective top edges of the side walls, the top wall being so shaped as to lie flush within the top edges of the side walls, so as to form a contiguous convex siir= face.
A concave bottom wall 19 is suitably secured between the wall H, the side walls I4 and the lower edge of the convex top wall I8 so as to enclose the vibrator unit within the housing thus provided.
The vibrator unit includes a motor conven tionally shown at 20 for rotating a shaft 21. The motor is controlled through a suitable switch 22 and receives electrical energy through a conductor 23, the latter having a plug 24 for insertion into an outlet of a source of current.
Upon the shaft 2| there is secured my improved rotor 25, shown in Figures 4 to 6, consisting of a body member having two right angularly disposed legs 21, these legs being of the same length and cross sectional area. The body is formed from metal and the legs 21 are an integral part thereof and connected with each other by a flat portion 28 of the body. As best seen in Figure 4, a tapped bore 29 is formed in the fiat portion 28 disposed medially of the legs 21, the bore 29 intersecting an opening 30 for reception of the motor shaft 2!. A set screw 3| engaged through the bore 29 will impinge upon the shaft 2| and thus secure the rotor to the shaft.
By reason of the fact that the legs 21 are at right angles to shaft 21 a force is exerted over one quarter of the circle described by the rotor under rotation, the force being distributed over a larger surface of the body undergoing treatment, the force further being amplified by reason of the mounting of the vibrator unit within the housing constructed of resonant wooden walls.
It will be apparent that by constructing the housing with convex and concave walls, various portions of the human body may be treated. For instance, the concave portion I6 will readily accommodate the abdomen, head, and other curved portions of the body, while the convex wall I8 will permit treatment of the arms and legs of a patient.
While I have shown and described a preferred form of the device, this is by way of illustration only, and I consider as my own all such modifications as fairly fall Within the scope of the appended claims.
I claim: I
1. A therapeutic vibrator comprising a housing, a motor mounted within and on a .Wall of said housing and said motor having an unbalanced rotor, said housing being formed from resonant wooden material whereby to amplify impulses produced by said rotor under rotation thereof.
2. A therapeutic vibrator comprising a housing having a vertical wall, a concave wall and a convex wall, a motor mounted in the housing and on the vertical wall, said motor having an unbalanced rotor, and means for actuating said motor.
3. A therapeutic vibrator comprising a housing having a flat vertical wall, a concave bottom wall, a convex top wall, and flat side Walls all of said walls being formed from a resonant wooden material, an electric motor mounted in said; housing and on said vertical wall and having a rotary shaft, and a rotor fixed to said shaft and comprising a body member having right angularly disposed legs of equal length and cross sectional area.
