A INVENTOR.
Tonous H. David BY 7;/ TJJ United States PatetitU 2,970,592 SPINAL COLUMN IMPACT DEVICE Tanous H. David, 5400 Aileen Way, Sacramento, Calif. Filed Jan. 29, 1959, Ser. No. 789,895 1 Claim. (Cl. 128-69) This invention relates to a device for creating a controlled impact about the spinal column and is an improvement of that type of apparatus as generally described in United States Letters Patent No. 1,722,662, issued July 30, 1929.
In treatments of the spinal column of the human back it is desirable to create controlled impact at preselected areas immediately over and adjacent the spinal column.
A principal object of this invention is to create a device which more specifically controls the impact that is created either on or immediately adjacent both sides of the spinal column.
A feature and advantage of this invention is the provision of two pads each of which is arranged to translate impact from a single plunger mechanism to the area immediately adjacent the spinal column. The pads are further facilitated with means of relative positioning with respect to the unitary plunger mechanism so that the relative amount of force translated to each pad from the plunger mechanism can be regulated.
Another object of this invention is to create an impact creating device for the spinal column employing a plunger mechanism having a plurality of stops which effectively limits the stroke of action of the plunger mechanism so that the translated force from the plunger mechanism to the back can be adjustably controlled.
Another feature and advantage of this invention is that a constant amount of pressure may be applied on the plunger mechanism against the back. However, the amount of force which is translated to the back may be varied by adjusting the stroke limits of the plunger mechamsm.
A further object of this invention is to provide pads which are individually mounted on spring means so as to create a relatively unyieldable head which is spring mounted in combination with the plunger mechanism to cushion the translation of impact from the plunger mechanism to the spinal column.
Other objects of the present invention will become apparent upon reading the following specification and referring to the accompanying drawings in which similar characters of reference represent corresponding parts in each of the several views.
In the drawings:
Fig. 1 is an elevational View of the principal embodiment of the invention.
Fig. 2 is a sectional view of Fig. 1 taken at line 2-2.
Fig. 3 is a cross-sectional view of Fig. 1 taken at line 33.
Fig. 4 is a fragmentary view showing the details of the shaft of the actuating mechanism for the impact creating device.
In the principal embodiment of the invention there is provided a cylindrical housing A having a bracket 16 mounted on the bottom of the housing and adapted to carry a pair of pads B and C.
A plunger mechanism D is mounted within cylindrical housing A to create impact within the housing which can be translated to pads B and C.
F ice Plunger mechanism D includes a shaft 20 with an actuating handle 23 mounted on the extreme end of the shaft external of housing A. The opposite end 24 of shaft 20 is interior of housing A and is guided by two cylindrical collars 25 for axial reciprocal movement longitudinally of the cylindrical housing.
The bottom of housing A is blanketed with a tip pad 28 which stops downward movement of the bottom end 24 of shaft 20 at the limit of its downward stroke. Impact is created by manually forcing handle 23 down wardly until bottom end 24 strikes the abutment 28 wherein the impact is translated to the housing and thence to the two pads B and C.
A spring 30 is mounted within housing A and is urged against pad 28 and the lower collar 25 to return shaft 20 to the normal position after the manually created impact.
Bracket 16 mounted on the bottom of housing A extends laterally outwardly to provide two outwardly extending ears 32. Each ear is provided with a longitudinal cutout 33. The pads are mounted on each ear 32 respectively via a screw 34 and a wing nut 35. The pads are adjustably mounted so that they may be moved inwardly toward or outwardly from the central axis of housing A. By this means either pad B or C may be positioned substantially closer to the central axis of housing A or alternatively further away from. The relative distance each pad extends outwardly from the central axis of housing A will determine the relative percentage of impact which is translated from the impact creating device to the pads. Thus for example, if pads B and C are at an equal distance from the central axis of housing A there will be an equal translation of impact to the two pads. This is useful when the two pads are centrally positioned over the spinal column so that the impact may be equal on both sides of the spinal column. Should the spinal column be misplaced to one side more than the other the pads can be alinged so that one of the pads would be substantially closer to the central axis of the impact creating device than the other pad. Thus by this means a greater percentage of the impact would be directed to one pad than to the other thus rendering the proper amount of relative pressure on both sides of the spinal column.
Pads B and C each comprise a base plate 40 which is connected directly to screw 34 and a spring member 41 connected to base plate 40 to provide a resilient buffer between the impact of the impact creating device and the pad mechanism. A semi-resilient material is used to form the engaging head 45 of pads B and C. Spring 41 is extremely important in forming a lbulfer between the translation of force from the impact creating device and head 45. With the provision of the spring the material forming head 45 may be even a rigid material such as hard rubber without causing any danger to the spinal column.
Shaft 20 is provided with a plurality of holes 48 formed to receive a stop member 49. With the provision of the stop member in a certain one of the holes the stroke limits of shaft 20 are limited wherein stop-member 49 engages the top wall 50 of housing A, thus limiting the downward movement of shaft 20 at a position substantially above the impact creating condition wherein end 24 impacts with pad 28. This is extremely useful where different opeartors desire to use the device and each operator has his own power of stroke. By adjusting "stop member 49 to the proper location the amount of Although the foregoing invention has been described in some detail by way of illustration and example for purposes of clarity of understanding, it is understood that certain changes andrnodifiactions may be practiced within the spirit of the invention asjlimited only by the scopelof the appended claim.
What is claimed is: a
In an impact deviee thecombination of a cylindrical housing, a shaft reciprocally mounted within said housing, spring bias means connected to said shaft and said housing to urge said shaft and housing to an extended position; a pair of ears mounted on the bottom of said housing extending in opposite directions outwardly from the central axis of said housing, pads adjustably mounted on said ears for relative movement toward and away from the central axis of said housing, said shaft being formed with a plurality of apertures, and a pin selectively mounted in one of said apertures, the top of said housing forming an abutment against which said pin engages when said shaft is forced downwardly.
