Various embodiments described herein relate to a handicap rail palm assist system and a method.
Handicap rails are placed in various places. Handicap rails help a handicapped person or when that is in a weakened condition to stand. In some cases the handicap rail is used by a person to stabilize their position and prevent falls. Falls many times lead to other health problems. In other instances, the person is unable to get from a sitting position to a standing position using a cylindrical rail. Most of the rails include a knurled or slightly roughened surface to prevent a user's hand from slipping. However, if a user has a less than strong grip then that person's hand may still slip. In addition, when in a weakened state, the actual placement of the hand on a handrail becomes most critical. A stronger person can grip a handrail in a general spot to get an upper body assist in moving from a sitting position to a standing position. When a person is weakened, they just do not have as much finger strength to pull themselves to the standing position. Generally, placement of the hand must be at just the right position and the hand can not slip for a weaker person to move from a sitting position to a standing position.
Many times, a major portion of the surface of the handicap rail is treated so that it can be more easily gripped or grasped. The surface of the handicap rail may be knurled in one instance. In another instance, the surface may be otherwise roughened to make it easier to hold a grip. In still other instances, a tape is applied to the major surface of the handicap rail. When a person is in a somewhat weakened state, it can be difficult or nearly impossible to maintain a grip on the handicap handrail even if it has been treated with a grip enhancing surface treatment, such as knurling or the like. When a user's grip is not maintained, it is difficult to get or maintain the needed leverage to use the handicap rail effectively. For example, a user might not be able to move from a sitting to a standing position.
The invention includes a mechanism that locks onto a handrail at a selected position. The invention may be locked permanently to one position or can be adjustable from one position to another along a handrail. If adjustable, it grips the handrail sufficiently to allow the mechanism to stay in position. The invention is a collar or cuff that attaches to the cylindrical body of the handrail. The collar or cuff generally attaches to the roughened portion of the handicap rail. The collar or cuff attaches to the cylindrical body at a specific position along the handicap rail. If a user has difficulty in maintain his or her grip, the cuff or collar acts as a stop which limits the motion of the user's hand. The cuff or collar is placed at a position that provides optimum or nearly optimum leverage. The user's hand may slip, but is stopped by the cuff or collar so that the person can then place the appropriate forces on the handicap rail to go from a sitting to a standing position without slipping. The cuff or collar prevents the user's hand from slipping down the rail. The cuff or collar acts on the edge of one's hand and acts in the same direction as a fiction force to stop the hand at the necessary position. The user can apply the strength of his or her fingers and his or her palm to the cuff or collar.
The cuff can be placed in a universal position in public applications, such as public restrooms, hospitals, grocery stores, department stores, doctor's offices, rehabilitation centers or the like. In a public place, most of the users will be able to use the cuff or collar to stop their hands so that they can apply the appropriate forces to the handrail to do their desired maneuver. Of course, when placed in a public application, many times the placement is less than optimal for many people. The placement is probably nearly optimal for some who are average. This may not work for a few and may require more energy than when the cuff or collar is optimally placed for most. In public settings where people of many sizes are using the handrail, it is contemplated that more than one collar can be placed on the handrail to accommodate the average smaller user, the average user, and the average taller or bigger user. Multiple collars can be added to accommodate many possible users.
The cuff or collar can also be used in private settings. For example, the cuff may be added to a handicap rail in a user's home or apartment. In this instance, the collar or cuff can be more accurately placed for a particular user so that the user can more easily move from a sitting portion to a standing position with greater ease. The collar might be placed closer to some users so that the hand slips to a stop position where the least amount of power is needed to do a desired maneuver. The most optimal position can vary based on the size of the person, their particular strengths and the like. Generally, the collar or cuff can be moved to different positions based on a scientific estimate for the optimum position. Ultimately, adjustments will have to be made to determine where a person can apply the most power while being the most comfortable. There may even be a tradeoff there between comfort and power. In some embodiments, the collar is moved around on a trial and error basis until the user finds a comfortable position where the user can place forces on the handicap rail to accomplish certain desired maneuvers.
One of the advantages of the handicap rail palm assist system 100 is that it is more safe to use, especially for a person with a weakened grip. The handicap rail palm assist system 100 essentially holds the patient's hand in place so that it does not slip as the user pushes off the rail or pulls on the rail, depending on the orientation of the rail 200. It prevents a user from slipping along the rail and dropping in an uncontrolled fashion. It also prevents falls which can be catastrophic for some users.
The cuff 100 or handicap palm assist 100 can be placed in a universal position in public applications on handicap rails, such as in public restrooms, hospitals, grocery stores, department stores, doctor's offices, rehabilitation centers or the like. In a public place, most of the users will be able to use the cuff or collar to stop their hands so that they can apply the appropriate forces to the handrail to do their desired maneuver. Of course, when placed in a public application, many times the placement is less than optimal for many people. The placement is probably nearly optimal for some who are average. This may not work for a few and may require more energy than when the cuff or collar 100 is optimally placed for most.
In another embodiment, a plurality of cuffs 100 or handicap palm assists 100 can be positioned on a handicap handrail. The plurality of cuffs or handicap palm assists can be positioned on a single rail to accommodate more users of various sizes. For example, one handicap palm assist 100 could be placed for users that are smaller than the average user, and another handicap palm assists 100 could be placed on a handrail for users that are larger than the average user. Yet another handicap palm assists 100 could be placed on the same handrail for the average user. In this embodiment, a high percentage of users could use one of the plurality of handicap palm assists 100 attached to a handrail. Of course, the handicap palm assists 100 will not be optimally placed for all but most users will be able to help themselves even though not optimally.
The cuff or collar 100 can also be used in private settings. For example, the cuff 100 may be added to a handicap rail in a user's home or apartment. In this instance, the collar or cuff 100 can be more accurately placed for a particular user so that the user can more easily move from a sitting position to a standing position. The collar 100 might be placed closer to some users so that the hand slips to a stop position where the least amount of power is needed to do a desired maneuver. The most optimal position can vary based on the size of the person, their particular strengths and the like. Generally, the collar or cuff 100 can be moved to different positions based on a scientific estimate for the optimum position. Ultimately, adjustments will have to be made to determine where a person can apply the most power while being the most comfortable. The adjustments can also be made to a position where the user is able to deliver adequate power to do a maneuver. There may even be a tradeoff there between comfort and power. In some embodiments, the collar is moved around on a trial and error basis until the user finds a comfortable position where the user can place forces on the handicap rail to accomplish certain desired maneuvers.
In one embodiment, the shells are symmetrically shaped. Each includes an attachment surface which is fit to a handrail 200. The handrails can have different diameters. Some may be smaller, such as 1.5 inches in diameter. Others may be bigger, such as 2.0 inches or even 2.5 inches in diameter. The outer surface of shell 110 includes a bulbous portion 114 and a rim 116, 117 near or at each of the ends of the first shell 110. Similarly, the outer surface of shell 120 includes a bulbous portion 124 and a rim 126, 127 near or at each of the ends of the first shell 110. It is contemplated that the outer surfaces of the shell 110 is made of a material which can be easily cleaned. For example, as shown, the outer surface of the shell is smooth to enhance to ability to clean and disinfect. The shells 110 are also made of a cleanable material, such as stainless steel.
The inner surfaces of each shell 110 and 120 is dimensioned so that it can attach to the surface of a hand rail 200. For example, if the handrail 200 has an outer diameter of 1.5 inches, the inner surface with be shaped and have a inner diameter that matches or is substantially the same. In addition, the inner surface may include a surface treatment that increases the coefficient of friction between the shell 110, 120 and the handrail 200. In some embodiments, the inner surface can have an elastomeric surface that compresses and grips the handrail 200. In other embodiments, the shells 110, 120 may have inner surfaces that have spray on enhancements. Fasteners connect the first shell 110 to the second shell 120. The fasteners are tightened to the point where the shells 110, 120 will not slip with respect to the handrail or slip with respect to one another. In this way, the first shell 110 and the second shell 120 form a collar or cuff 100 which will stop a person's hand when gripped. The openings 111, 112 align with the openings 121, 122 so that one fastener can go through the openings 111, 121 and another fastener can go through openings 112, 122. The fasteners are sized so as not to protrude from any of the openings 111, 112, 121, 122. Furthermore, the openings include a recess so that the heads of the fasteners will not protrude. This is a safety feature which prevents users from cutting themselves or otherwise injuring themselves on the fasteners. The fasteners may also be made of stainless steel.
As shown in
It is contemplated that the cuff or collar could be sized differently to fit different sized handrails. Furthermore, it is contemplated that the design could differ to fit various user's hands. The size could be sized to the hands of the user. Different dimensions could also be used for different sized handrails.
In summary, a handicap palm assist system includes a first shell, a second shell, and at least one connector for removably attaching a first shell to the second shell. The handicap palm assist system also includes a handrail. The first shell and second shell sized to removably attach to the handrail. The first shell has a first concave portion having an inside diameter substantially equal to the outside diameter of the handrail. The second shell has a second concave portion having an inside diameter substantially equal to the outside diameter of the handrail. The first shell and the second shell place a force on the outside diameter of the handrail when connected to one another. When the two shells are loosely connected to one another, they can be moved along the handrail to adjust the position of the palm assist with respect to the handrail. Once in position, the two shell connectors can be tightened. This tightens the two shells with respect to one another and with respect to the handrails with sufficient force that the two shells do not move with respect to the handrail In one embodiment, the first shell and the second shell are symmetrical. In another embodiment, the concave portion of the first shell, and the concave portion of the second shell further include a friction material. The friction material increases the coefficient of friction between the shells and the handrail so less force is needed to connect the two shells to the handrail to prevent slippage. In one embodiment, the outer surface of at least one of the first shell and the outer surface of the second shell includes a surface treatment to enhance gripping of the shell. Of course, the surface treatment, in some embodiments, should be cleanable. In another embodiment, the first shell and the second shell are asymmetrical. In still another embodiment, one the first shell and the second shell includes a handle. In yet another embodiment, at least one of the first shell and the second shell includes a screw opening therein. The screw opening accepts a set screw which can be tightened so that one end of the set screw contacts the handrail.
A method for adding to the assistance provided by a handrail includes placing a first concave surface of a first shell portion onto a handrail, placing a second concave surface of a second shell portion onto a handrail, and connecting the first shell to the second shell to form a handicap palm assist unit so that the first shell and the second shell are substantially immovable with respect to the handrail. The method also can include adjusting the position of the first shell and second shell along the length of the handrail. The method also includes adjusting the attachment point and position of the first shell and second shell along the length of the handrail to provide additional leverage for a user when using the handrail. In some embodiments, more than one set of shells are attached to the handrail. In one embodiment, the first shell portion and the second shell portion are substantially symmetrical while in another embodiment, the first shell portion and the second shell portion are asymmetrical. In one embodiment of the method, the larger of the first shell portion and the second shell portion is placed on the handrail to provide additional leverage for a user. The larger of the first shell portion can be placed above the second shell portion on the handrail or can be placed below the second shell portion on the handrail.
