Description:
FIELD OF THE INVENTION 
     The present invention relates to adjustable spinal rehabilitation devices, and more particularly, to a three-dimensional spinal rehabilitation device equipped with elevation adjustment mechanisms for adjusting inclinations of pads on a bed frame and equipped with an inverted U-shaped frame having pulley trains and two tractors, so as to give a pull at a rehabilitation patient&#39;s spine from the front or sideward, with the rehabilitation patient lying on the pads of adjustable inclinations. 
     BACKGROUND OF THE INVENTION 
     U.S. Pat. No. 7,127,757, entitled Adjustable Traction Table, discloses a rehabilitation bed capable of being raised at an angle to the horizontal so as for a rehabilitation patient lying on the rehabilitation bed to receive spinal rehabilitation therapy. However, after putting the rehabilitation patient in place on the rehabilitation bed, moving the rails thereunder, and adjusting four jacks to change inclination of the two-segment rehabilitation bed, a physical therapist performs spine-stretching rehabilitation therapy on the rehabilitation patient by giving a pull at the rehabilitation patient&#39;s spine, that is, exerting a gravitational force on the rehabilitation patient&#39;s spine in a direction parallel to the horizontal. A drawback of U.S. Pat. No. 7,127,757 is that it is impossible to ergonomically adjust the inclination of the rehabilitation bed without using an auxiliary tool, thereby compromising the quality of spine-stretching rehabilitation therapy and the efficacy of the rehabilitation bed. Another drawback of U.S. Pat. No. 7,127,757 is that it is time-consuming to adjust the inclination of the two-segment rehabilitation bed by the four jacks thereunder and thereby inconvenient to use the rehabilitation bed. Yet another drawback of U.S. Pat. No. 7,127,757 is that only inclination relative to the two-segment rehabilitation bed itself can be adjusted due to the structure thereof, and thus the rehabilitation patient is uncomfortable and perceives body stiffnesss after maintaining the same posture on the rehabilitation bed for a long period of time, and in consequence the efficacy of spine-stretching rehabilitation therapy deteriorates. 
     In view of the aforesaid drawbacks of the prior art, the inventor of the present invention endeavored to improve the prior art and thereby invented an adjustable spinal rehabilitation device to overcome the aforesaid drawbacks. 
     SUMMARY OF THE INVENTION 
     A primary objective of the present invention is to provides an adjustable spinal rehabilitation device characterized by integration of a bed frame and an inverted U-shaped frame to enhance efficacy of rehabilitation therapy performed on a rehabilitation patient&#39;s cervical spine, thoracic spine, and lumbar spine, and efficacy of pelvic rehabilitation performed on the rehabilitation patient. 
     Another objective of the present invention is to provide an adjustable spinal rehabilitation device characterized by streamlined elevation adjustment mechanisms provided between the bed frame and pads such that it is easy to adjust inclination of both sides of the pads. 
     Yet another objective of the present invention is to provide an adjustable spinal rehabilitation device with three pads disposed on the bed frame, allowing inclination of both sides of each of the pads to be freely adjusted so as to render the rehabilitation bed fit for the rehabilitation patient lying thereon with a specific lying posture and therefore ensure the rehabilitation patient&#39;s comfort. 
     To achieve the above and other objectives, the present invention provides an adjustable spinal rehabilitation device, comprising: a bed frame, three soft pads, five elevation adjustment mechanisms, an inverted U-shaped frame, two tractors, and five fastening belts. The bed frame is provided with the three soft pads on which a rehabilitation patient lies. Four fastening belts are tied to the bed frame bilaterally such that the rehabilitation patient is fixed in position to the bed frame. The five elevation adjustment mechanisms are positioned between and coupled to the bed frame and the soft pads. Inclinations of the soft pads are adjustable with the five elevation adjustment mechanisms such that the rehabilitation patient lies on the soft pads comfortably. The inverted U-shaped frame is provided outside the bed frame. The bed frame is coupled to the inverted U-shaped frame from below. Two tractors are provided outside the inverted U-shaped frame. A cord is connected to and extended from each of the two tractors. The cords penetrate holes of the inverted U-shaped frame so as for the cords to be coupled to pulley trains disposed on rails provided on inner sides of the inverted U-shaped frame, respectively. The cords are coupled to two of the fastening belts, respectively. The tractors pull the rehabilitation patient so as to increase inclination of the rehabilitation patient&#39;s thoracic spine and lumbar spine to a required angle and pull the rehabilitation patient&#39;s cervical spine from a required angle with a view to performing spinal rehabilitation therapy on the rehabilitation patient&#39;s cervical spine, thoracic spine, and lumbar spine efficiently. 
     The present invention is hereunder illustrated with preferred embodiments in conjunction with the accompanying drawings, so that one skilled in the pertinent art can easily understand the structures, features, and effects of the present invention.

     Referring to  FIG. 9 , the head pad  105  is provided with two bars  1051  parallel to each other, and two holes  1011  corresponding in position to the two bars  1051  are formed at an end of the first pad  101 , thereby allowing the two bars  1051  of the head pad  105  to be inserted into the two holes  1011  of the first pad  101  so as for the head pad  105  to be coupled to the first pad  101 . 
     Referring to  FIG. 11 , two bars  1061  extend from beneath the foot pad  106 , and two engaging rings  1031  parallel to each other and corresponding in position to the two bars  1061  are provided beneath the third pad  103 , thereby allowing the two bars  1061  of the foot pad  106  to be inserted into the two engaging rings  1031  of the third pad  103  (see  FIG. 2 ). The two engaging rings  1031  are each coupled to a screw element  1032 . Loosening two the screw elements  1032  allows the two bars  1061  to move within the two engaging rings  1031 , and in consequence the foot pad  106  can be moved forward or backward relative to the third pad  103  so as to adjust the distance between the foot pad  106  and the third pad  103 . 
     Referring to  FIG. 2  through  FIG. 6 , to use the adjustable spinal rehabilitation device  1  of the present invention, the front or the rear of the first pad  101 , second pad  102 , and third pad  103  are either lifted or lowered to adjust inclination thereof such that the inclined first, second, and third pads  101 ,  102 ,  103  fit the rehabilitation patient&#39;s lying posture (see  FIG. 3 ), thereby allowing spinal rehabilitation therapy to be performed on the rehabilitation patient in a lying posture. Take the first pad  101  as example: in a preferred embodiment of the front-lift first pad  101 , the front of the first pad  101  is lifted, and thus a point located at the front of the first connecting member  21  becomes an axle because it is the point whereby the first connecting member  21  is pivotally coupled to the chest-section frame  11 , and thus the first connecting member  21  and the second connecting member  22  overlap to lie on a plane and move upward together with the first pad  101  to result in an angle of inclination; meanwhile, the first bar  23  at the rear of the first connecting member  21  moves, when driven by the first connecting member  21 , upward along the hole  256  of the block  255  of the first shaft  25  to result in an angle of inclination and therefore engage the hole  256  of the block  255  of the first shaft  25 ; and in consequence the front of the first pad  101  can be lifted to maintain a fixed angle of inclination and thereby enhance the comfort of the rehabilitation patient receiving spinal rehabilitation therapy. 
     Holding the handles  251  and turning the first shaft  25  by the handles  251  not only stretches the resilient elements  254  coupled to two inner sides of the chest-section frame  11  but also moves the block  255  of the first shaft  25  forward to end up with the same angle of inclination as the first bar  23 , thereby allowing the first bar  23  to move downward along the hole  256  of the block  255  and allowing the first connecting member  21  and the second connecting member  22  which overlap to lie on a plane to move downward together with the first pad  101 ; hence, an angle of inclination of the front of the first pad  101  can be reduced by adjustment. Afterward, releasing the handles  251  of the first shaft  25  allows the resilient elements  254  that flank the chest-section frame  11  to restore the block  255  to the original position such that the first bar  23  is fixed in position to the hole  256  of the block  255  of the first shaft  25 . 
     In a preferred embodiment of the rear-lift first pad  101 , the rear of the first pad  101  is lifted (see  FIG. 3 ), and thus a point located at the rear of the first connecting member  21  becomes an axle because it is the point whereby the first connecting member  21  is pivotally coupled to the second connecting member  22 , and in consequence the second connecting member  22  moves upward together with the first pad  21  to result in an angle of inclination; meanwhile the second bar  24  at the rear of the second connecting member  22  moves, when driven by the second connecting member  22 , upward along the hole  266  of the block  265  of the second shaft  26  to result in an angle of inclination and therefore engage the hole  266  of the block  265  of the second shaft  26 ; and in consequence the rear of the first pad  101  can be lifted to maintain a fixed angle of inclination and thereby enhance the comfort of the rehabilitation patient receiving spinal rehabilitation therapy. 
     Holding the handles  261  and turning the second shaft  26  by the handles  261  (see  FIG. 4 ) not only stretches the resilient elements  264  coupled to two inner sides of the chest-section frame  11  but also moves the block  265  of the second shaft  26  forward to end up with the same angle of inclination as the second bar  24 , thereby allowing the second bar  24  to move downward along the hole  266  of the block  265  and allowing the second connecting member  22  to move downward together with the first pad  101 ; hence, an angle of inclination of the rear of the first pad  101  can be reduced by adjustment. Afterward, releasing the handles  261  of the second shaft  26  allows the resilient elements  264  that flank the chest-section frame  11  to restore the block  265  to the original position such that the second bar  24  is fixed in position to the hole  266  of the block  265  of the second shaft  26 . 
     The front or the rear of the second pad  102  is either lifted or lowered in the same way as the first pad  101  and thus detailed description thereof is omitted herein. 
     Referring to  FIGS. 1 ,  3 ,  4 ,  7  and  9 , in a preferred embodiment of the front-lift third pad  103 , to use the adjustable spinal rehabilitation device  1  of the present invention, the front of the third pad  103  is lifted, and thus a point located at the rear of the third pad  103  becomes an axle because it is the point whereby the third pad  103  is pivotally coupled to the leg-section frame  13 , and thus the third connecting member  61  moves upward together with the third pad  103  to result in an angle of inclination; meanwhile, the third bar  62  and fourth bar  63  pivotally coupled to the third connecting member  61  move, when driven by the third connecting member  61 , upward along the holes  646  of the two blocks  645  of the third shaft  64  to result in an angle of inclination and therefore engage the holes  646  of the two blocks  645  of the third shaft  64 ; and in consequence the front of the third pad  103  can be lifted to maintain a fixed angle of inclination and thereby enhance the comfort of the rehabilitation patient receiving spinal rehabilitation therapy. 
     Holding the handles  641  and turning the third shaft  64  by the handles  641  not only stretches the resilient elements  644  coupled to two inner sides of the leg-section frame  13  but also moves the two blocks  645  of the third shaft  64  forward to end up with the same angle of inclination as the third bar  62  and the fourth bar  63 , thereby allowing the third bar  62  and the fourth bar  63  to move downward along the holes  646  of the two blocks  645  and allowing the third connecting member  61  to move downward together with the third pad  103 ; hence, an angle of inclination of the front of the third pad  103  can be reduced by adjustment. Afterward, releasing the handles  641  of the third shaft  64  allows the resilient elements  644  that flank the belly-section frame  12  to restore the two blocks  645  to the original position such that the third bar  62  and the fourth bar  63  are fixed in position to the holes  646  of the two blocks  645  of the third shaft  64 . 
     Referring to  FIGS. 1 and 10 , in a first preferred embodiment of application of the adjustable spinal rehabilitation device  1 , the two first connecting elements  90  provided for the two ends of the first fastening belt  81  are coupled to the hangers  161  provided for the two rods  16 , respectively. After the rehabilitation patient has lain on the first pad  101 , second pad  102 , and third pad  103  on the bed frame  10  inclined at a well-adjusted angle, the first fastening belt  81  is fastened to the rehabilitation patient&#39;s neck, and then the second fastening belt  82  is wound onto the rehabilitation patient&#39;s waist; afterward, the two first connecting elements  90  provided for the two ends of the second fastening belt  82 , respectively, are coupled to the second connecting element  91  coupled to the front end of the cord  7021  extending from the second tractor  702  such that the second fastening belt  82  can move within the rails  72  when driven by the pulley train  731 , thereby changing the position of the second fastening belt  82  relative to the rehabilitation patient. Then, the two ends of the third fastening belt  83  are coupled to the rods  14  that flank the bed frame  10  such that the rehabilitation patient&#39;s lower limbs are fixed in position. Then, the rehabilitation patient&#39;s head is received in the socket  841  provided for the fourth fastening belt  84 , and the first connecting element  90  corresponding in position to the socket  841  is coupled to the second connecting element  91  coupled to the front end of the cord  7011  extending from the first tractor  701 . Then, the first tractor  701  generates a force whereby the rehabilitation patient&#39;s head is pulled downward by means of the cord  7011  extending from the first tractor  701  and thereby the rehabilitation patient&#39;s head is fixed in position; meanwhile, the cord  7011  changes the path thereof by following the pulley train  731  of the rails  72  beneath the inverted U-shaped frame  70 , and then the cord  7011  is guided through the holes  75  of the rails  72  at the front of the inverted U-shaped frame  70  by the rollers  76  before being tautened by the first tractor  701 . 
     Afterward, the second tractor  702  generates a force whereby the rehabilitation patient&#39;s back is lifted; meanwhile, the cord  7021  changes the path thereof by following the pulley train  731  of the rails  72  on top of the inverted U-shaped frame  70  and following the hooks  74  hung on the rails  72  on top of the inverted U-shaped frame  70 , and thus the cord  7021  is guided through the holes  75  of the rails  72  at the rear of the inverted U-shaped frame  70  by the rollers  76  before being tautened by the second tractor  702 , so as for spinal rehabilitation therapy to be performed on the rehabilitation patient. 
     Referring to  FIGS. 1 and 12 , in a second preferred embodiment of application of the adjustable spinal rehabilitation device  1 , the fourth pad  104  is positioned between the rods  16  that flank the chest-section frame  11 , to allow the rehabilitation patient to sit on the inclination-adjusted first pad  101  and second pad  102  on the bed frame  10  and let the rehabilitation patient&#39;s spine rest against the fourth pad  104 . Then, the rehabilitation patient&#39;s head is received in the socket  851  of the fifth fastening belt  85 , and the rehabilitation patient&#39;s two axillae are held by shoulder straps  852 . Then, the first connecting element  90  provided for the fifth fastening belt  85  is coupled to the second connecting element  91  coupled to the front end of the cord  7011  connected to and extended from the first tractor  701 . Afterward, the first tractor  701  pulls the rehabilitation patient&#39;s head and back backward by means of the cord  7011  extending from the first tractor  701 ; meanwhile, the cord  7011  changes the path thereof by following the pulley train  731  of the rails  72  at the front of the inverted U-shaped frame  70 , and then the cord  7011  is guided through the holes  75  of the rails  72  at the front of the inverted U-shaped frame  70  by the rollers  76  before being tautened by the first tractor  701 , so as for spinal rehabilitation therapy to be performed on the rehabilitation patient&#39;s cervical spine, thoracic spine, and lumbar spine. 
     Owing to the integration of a bed frame and an inverted U-shaped frame of the present invention, spinal rehabilitation therapy can be performed on a rehabilitation patient&#39;s cervical spine, thoracic spine, and lumbar spine, and pelvic rehabilitation therapy can be performed on the rehabilitation patient. In a preferred embodiment of the present invention, working the bed frame in conjunction with the inverted U-shaped frame equipped with at least one pulley train enables adjustment of inclinations of a rehabilitation bed and soft pads thereon according to spinal ergonomic principles and thereby enhances the efficacy of rehabilitation therapy performed on the rehabilitation patient&#39;s cervical spine, thoracic spine, and lumbar spine and the efficacy of pelvic rehabilitation therapy performed on the rehabilitation patient—an advantage and effect of the present invention. 
     Elevation adjustment mechanisms of the present invention are equipped with shafts and bars, and the bars are coupled to connecting members beneath pads and engage holes formed in blocks coupled to the shafts. This expedites elevation or depression of the front or the rear of the pads and enable inclination of the pads to be adjusted easily—another advantage and effect of the present invention. 
     As disclosed in the present invention, the bed frame has three pads thereon, and the front or the rear of each of the pads can be lifted or lowered to adjust the inclination of each of the pads freely so as to render the rehabilitation bed fit for the rehabilitation patient lying thereon with a specific lying posture and therefore ensure the rehabilitation patient&#39;s comfort—yet another advantage and effect of the present invention. 
     The above description serves to expound preferred embodiments of the present invention rather than limit the scope of application of the present invention. Persons skilled in the art should be able to make obvious changes or modification of the present invention without departing from the substantive disclosure of the present invention.
