CROSS-REFERENCE TO RELATED APPLICATION(S) This application is a non-provisional patent application that claims priority to Provisional Patent Application No. 60/588,678 filed on Jul. 16, 2004, entitled, “Bed Side Rail Method and Apparatus,” which is incorporated herein by reference thereto.
BACKGROUND In general, bedside support devices am provided to assistance to patients or other individuals in need of a certain amount of support when getting out of bed or repositioning themselves. Many of the prior art devices have a static portions that are rigidly attached to the central lateral portion of a bed or adjacent structure which often times places a patient in peril in the event she is wedged between the static rigid portions and the lateral region of the bed. It is therefore in objective to provide a bedside rail support that is adapted to allow a handle region which repositions laterally and provides sufficient vertical support to the patient so she can reposition herself to a sitting position and stand with a certain amount of assistance from the bedside support device.

DETAILED DESCRIPTION The bedside support device 20 as shown in FIG. 1 is shown in one form. The general environment for the bedside support device 20 is shown in FIG. 5 where the device 20 is mounted to a bed indicated at 10. The bed comprises a bed frame 11. The bed frame comprises a corner region 12 and a lateral region 13. An axis system 14 is defined as shown in FIG. 4. The longitudinal axis 15 extends in a longitudinal direction and generally indicates the same. The lateral axis 16 indicates a lateral direction and the vertical axis 17 indicates a vertical direction. Of course the axis system 14 is for general reference purposes and indicates general directions that are not categorically perfectly orthogonal to one another.
With the foregoing in mind, there will first be description of the mechanical components of one form of the bedside support device 20 with reference to FIGS. 1-3 followed by a description of a the of operation of the bedside support device 20.
As shown in FIG. 1, the bedside support device 20 comprises a mounting region 22 and a support bar 24. The mounting region 22 has a pivot attachment member 26 that is fixedly attached to a base frame 28. In one form, the base frame 28 comprises a first member 30 and a second member 32. The first and second members 30 and 32 are fixedly attached at the juncture 34. In one form, these items are permanently attached to one another in an orthogonal relationship and are adapted to be fitted to a corner region 13 of the bad frame as shown in FIG. 3. In one form, the mounting region 22 is made from a suitable metal in a configuration such as channel iron or the like to be adapted to handle the transmitted loads from the support bar 24.
The pivot attachment member 26 in one form is a tubular sleeve 40 having an internal bushing or bearing to provide rotation substantially about a vertical axis. The internal bushing or bearing provides an internal cavity adapted to receive the lower portion of the base region 60 of the support bar 24. As shown in FIG. 3, the base region 60 extends through the lower region of the pivot attachment member 26. In one form, the pivot attachment member 28 has a securing mechanism 46 having a spring-loaded pin device adapted to be received by channels such as channel 443 as shown in FIG. 3. There can be numerous channels 48 in the base region 60 of the support bar 24. As shown in FIG. 3, an interior channel behind the pivot attachment member 26 is present where the security mechanism 26 has an internal pin extending therein. As shown in FIG. 3, the channel 48 has a first engagement surface 50 and a second engagement surface 52. These engagement surfaces are adapted to be received by the outer cylindrical surface of the pin of the security mechanism 46 in order to limit the rotational range of the support bar 24. By providing a plurality of slots 48 the height of the support bar 24 can be effectively adjusted. As described further herein, the support bar 24 is adapted to freely rotate away from the lateral region of the bed so the occupant of the bed is not inadvertently pinched if he or she accidentally undergoes a traumatic fall or rolls off the bed.
As shown in FIG. 2, the support bar 24 comprises a base region 60 and a handle region 62. The handle region 52 comprises a substantially horizontally extending grasping area 63. The base region 60 as described above is adapted to cooperate with the pivot attachment member 26 of the mounting region 22 to provide a one degree of freedom motion of rotation substantially about a vertical axis. Of course other forms of repositioning can be obtained such as the use of a linkage system instead of a peer rotational system. However, a pivot rotation about a substantially vertical axis is one way of allowing repositioning of the handle region 62 with respect to the bed frame.
Essentially, the base region 60 and handle region 62 are fixedly connected at a joinder portion 64. In a preferred form of manufacture, the regions 60 and 62 are of a single piece of metal that is that substantially at a ninety-degree angle from one another, however other angle relationships can be employed. Further, the lower portion of the base region as mentioned above is adapted to extend through the open chamber region of the pivot attachment member 26 to provide a limited rotational movement therein.
In one farm, the resistance of the rotation about a vertical axis can be provided to dampen the rotational movement of the handle region 62. This can be accomplished by having a sleeve that is constricted to provide circumferential friction about the base region 22. This could be advantageous where it is desired to have a handle region 62 that repositions with a certain degree of resistance to provide some stability but will reposition in the event the patient falls off the bed and requires a safety limitation to fall freely without being pinched or strangled by any fixed open perilous gaps.
Now referring to FIG. 4, a patient 70 is shown lying in the bed 10. As shown in this figure, the patient grasps the handle region 62 and places a lateral and vertically downward force thereto. This load is transmitted to the base region 60 and through the pivot attachment member 26. This load is transmitted to the mounting region 22. The mounting region 22 in one form is fixedly attached to the corner region 12 of the bed 10. This mounting region should be positioned at a corner region that has the lowest probability of a patient falling. In other words, the mounting region 22 would not be positioned in the central lateral portion of the bed because of the hazard of having a rigid structure attached to the bed frame which presents a perilous choking and suffocating hazard to a patient in need of assistance.
Now referring to FIG. 5, the patient 70 was able to pull herself to a sitting position alongside the lateral region 13 of the bed 10 from this position as shown in FIG. 5, the patient 70 desires to stand and move away from the bed 10. Therefore, the patient will put a vertical load downwardly as indicated by the force vector 72 upon the handle region 62 of the bedside support device 20. The patient 70 can further flex her upper torso and have a laterally inward force to position her center of gravity near the handle region 62. Once the user stands up as Shawn in FIG. 6, the handle region 62 freely repositions to a lateral direction and in one form pivots in a lateral and longitudinally forward position as shown in this figure. The patient can continue to put a downward force upon the handle region 62 to assist her. This is particularly advantageous when the patient is getting up after a period of not being on her feet and she requires the blood to get flawing to her legs for proper bipedal motion. In the event that her foot is asleep or she suffers any other temporary or permanent ailment, the patient 70 can back up where the handle region 62 freely allows this reverse motion and she can sit back down on the bed safely as shown in FIG. 5.
If the patient feels that she can travel away from the bed, she can reposition the handle region 62 to a fully extended lateral position as shown in FIG. 7 whereby at this stage the patient 70 has the confidence to walk without any assisting device. Alternatively, a mobile bipedal motion assisting device such as a walker could be positioned at the distal lateral location from the bed 10 and the user could grasp this device to transfer herself to a desired location.
Of course various modifications and alterations can be performed without departed from the spirit scope of the invention.
From the foregoing, it will be appreciated that specific embodiments of the invention have been described herein for purposes of illustration, but that various modifications may be made without deviating from the spirit and scope of the invention. Accordingly, the invention is not limited except as by the appended claims.
