## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a Continuation of U.S. application Ser. No. 11/230,997 filed Sep. 20, 2005, which is a Continuation of U.S. application Ser. No. 10/638,202 filed Aug. 11, 2003, which applications are hereby incorporated by reference in their entirety.


BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates in general to a rehabilitation support system particularly adapted for utilization by those having debilitating ambulatory conditions due to their age or injuries they have suffered and more specifically relates to a rehabilitation support system designed for safety, comfort and simplicity of use in a wide variety of applications.
2. Description of the Prior Art
Over the years there have been numerous types of devices that have been designed to serve as solutions to the serious problem health care facilities face in having insufficient personnel for properly assisting patients with debilitating ambulatory conditions as a result of their age, disease or injury. The need for such devices is caused by the fact that it may require two to three therapists to safely treat a patient during rehabilitation activities. Typically, health care facilities do not have sufficient manpower available for properly assisting a large number of patients in performing the optimum amount of rehabilitation activities they require. This is particularly true for those patients that require dynamic exercise, gait training or balance exercising as part of their treatment while standing in an erect position.
Some of the various types of known prior art rehabilitation support systems are described in U.S. Pat. Nos. 3,780,663; 4,725,908; 4,164,350 and 4,911,426. The systems disclosed in such prior art patents generally involve patient support systems that include a support harness of some kind for the patient that is suspended from an overhead rail on which a movable mechanism is located so that a patient is supported in an erect position as rehabilitation activities are performed.
The present invention is an improvement over those prior art devices described above in that it allows freedom of movement for the patient in all directions or planes, meaning side-to-side, forward and back and even up and down with transfers or on a step, and can be utilized in combination with a treadmill, stationary bike, balance machine, etc.
BRIEF SUMMARY OF THE INVENTION
The present invention provides an overhead support apparatus for assisting a user while performing physical activities and includes a track assembly supported by the ceiling, and a safe and secure suspension assembly that is depended from the track assembly and is attached to the user so that the apparatus acts to prevent the user from falling down during physical activities.
The suspension assembly includes a trolley adapted to traverse the track assembly, a locking snap assembly attached to the trolley and associated with a swivel means and an adjustable lanyard that is connected to the swivel means at one end and to a body harness at its opposite end, which harness has straps for encircling the torso and legs of a user. The snap assembly has an opening that is normally closed by a keeper that is spring loaded to be maintained in a closed condition. A locking lever is associated with said keeper to normally prevent movement of the keeper to an open condition.
The foregoing and other advantages of the present invention will appear from the following description. In the description, reference is made to the accompanying drawings, which form a part hereof, and in which there is shown by illustration and not of limitation a specific form in which the invention may be embodied.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to the drawings and with reference first to FIG. 1, a preferred embodiment of the rehabilitation support apparatus of the present invention is shown at 10 and it is specifically adapted for providing assistance to a user while performing rehabilitation physical activities such as dynamic exercise, gait training or balance exercising as part of their treatment while standing in an erect position.
The support apparatus 10 includes a track assembly 12 that is preferably hung by means well-known in the art from a ceiling (not shown) and a safe and secure suspension assembly 14 that is depended from the track assembly 12 and is attached to the user so that the apparatus 10 acts to prevent the user from falling down during physical activities. The suspension assembly 14 is formed of a trolley assembly 16, a locking snap assembly 18, a swivel 20, an adjustable lanyard 22 and a body harness 24 that is preferably secured around the torso and legs of a user.
Referring now to FIG. 2, the trolley assembly 16 has an upper body portion 30 that serves as a mounting mean for two pairs of wheels 32 and 34 that are mounted on wheel axles 36 and 38 positioned through the trolley assembly body portion 30 in such fashion so as to place the wheels 32 and 34 in tandem. The lower section of the body portion 30 includes a pair of spaced apart trunnions 42 in which a support pin 44 is secured. As best shown in FIG. 3, the trolley assembly 16 is designed to fit within the interior of the track assembly 12, with the wheels 32 and 34 riding on spaced apart bottom edges 46 of the assembly 12.
The locking snap assembly 18, as best shown in FIG. 4, has a hook shaped main portion 50 to define an opening 52. Pivotally mounted on the main portion 50 is a keeper lever 54 that is spring biased to normally close the opening 52. A locking lever 55 is also pivotally mounted to the main portion 50 and has a bottom end 56 with an abutment 58. The lever 55 is spring biased to normally place the abutment 58 into a position directly beneath a shoulder 60 on the keeper lever 54 to prevent pivotal motion thereof into an open condition. Thus, the snap assembly 18, when secured upon the trolley assembly pin 44, is maintained in position by the keeper lever 54 and locking lever 55 to prevent the suspension assembly 14 from being inadvertently removed or to accidentally come loose from the trolley assembly 16. The bottom of the snap assembly 18 terminates in a pintle 66 that serves as a mount for an eye ring 68 to form a swivel 70.
Attached to the eye ring 68 is the upper end of the adjustable lanyard 22 and the bottom end of the lanyard 22 is attached to a second snap assembly 74, as shown in FIG. 6. The assembly 74 is attached to a sturdy harness ring 75 that is fixed to the shoulder portion of the harness 24. Similar to the snap assembly 18, the snap assembly 74 has a keeper lever 76 that is normally locked in a closed condition by a spring loaded locking lever 78.
As indicated in FIG. 1, the lanyard 22 is formed from top middle and bottom strip portions 81a, 81b and 81c respectively that are connected together preferably by an upper cam buckle 80 and a main cam buckle 82 for adjusting the length of the lanyard 22. The upper cam buckle 80 is used to adjust the height of the main cam buckle 82 so that it can easily be reached by a therapist for adjustment. The main cam buckle 82 is used to lower or raise the snap assembly 74 for connecting and disconnecting a user.
As shown in FIG. 7, the cam buckle 80 includes a pair of spaced apart sidewalls 94, an upper fixed post 96 that is attached to the lower end of the upper strap portion 81a. The bottom of the buckle 80 has a second fixed post 98 adjacent a spring biased brake lever 100. The upper portion of the middle strap portion 81b is threaded between the post 98 and a brake lever 100 so that normally the brake 100 holds the strap portion 81b in a fixed position. The cam buckle 82 operates in a similar fashion. However, the bottom strap portion 81c has a free end 102 with an enlarged portion 104, such as another cam buckle (see FIG. 6) that serves as a safety brake to prevent dropping of the user through careless operation of the apparatus 10.
The harness 24 includes a shoulder strap portion 84 that is positioned about the shoulders of the user and terminates in a pair of chest straps 86 that are connectable together by a seatbelt type fastener 88 to secure the shoulder portion to the torso of the user. The bottom portion of the harness 24 includes straps 90 with release buckles 92 that wrap around a user's legs. Consequently, the harness 24 is designed to support a user's body during a fall in a sufficiently high number of body areas so that no one area will be subjected to such high pressure so as to be likely to cause injury to the user.
Thus, the present invention provides a novel, efficient and simplistic means for providing assistance to a user while performing rehabilitation physical activity. Although the support apparatus 10 of the present invention has been described with respect to a preferred embodiment, it should be understood that such embodiment may be altered without avoiding the true spirit and scope of the present invention. It is also important to note that various modifications may be made to the disclosed embodiment.
