Abstract
A removable floor mounted support pole for assisting elderly and disabled persons with standing from a seated surface, and providing adjacent support while moving on, to, and from a bed, bathtub, or toilet. The apparatus is designed to be installed and used typically in buildings with a concrete slab type floor such as a hospital or nursing home. The apparatus comprises two major assemblies: firstly, a floor receptacle which is installed permanently within a concrete slab type floor, and secondly, a support pole assembly which removably fastens into the floor mounted receptacle. When the support pole is not required, it may be removed in less than a minute, and placed in storage. The floor receptacle is sealed with a flush cap when a support pole is not installed within.
The present design includes several novel features including: a novel fastening means to secure the support pole assembly into the floor receptacle, novel mating geometry to ensure minimal movement of the pole while installed in the floor receptacle, a novel means of using the support pole as a tool to disengage the floor receptacle cap, and a novel method of storing the sealing cap of the floor receptacle within the pole while the pole is installed in the floor receptacle.
Description
- 1. Field of the Invention
- this invention relates to a removable floor mounted support pole for assisting elderly and disabled persons with standing from a seated surface, and providing adjacent support while moving on, to, and from a bed, bathtub, or toilet. The apparatus is designed to be installed and used in buildings with a concrete slab type floor, such as in a hospital or nursing home.
- 2. Description of Prior Art
- Elderly and disabled persons often require support surfaces such as hand rails or grasping bars to pull themselves up to a standing position from a bed, toilet, chair or wheelchair. Support surfaces are also needed to help bear their weight while transferring between two functional surfaces such as a bed and wheelchair. Support surfaces are also helpful to lower or steady themselves in the event of a sudden loss of balance, and thereby preventing a fall, which in more senior individuals can result in a serious injury such as a broken hip. Further, in an institutional setting, such as a hospital, support surfaces are important to allow the patient to assist with weight bearing to prevent injury to care staff who are assisting the patient with standing or transferring.
- There are numerous prior art devices for these purposes including; wall mounted grab bars, mobile wheeled walkers, floor to ceiling support poles, bed mounted support rails and permanent floor mounted rails. However, each of these devices has its disadvantages: Wall mounted grab bars cannot provide support in the middle of a room where most standing and transfer actions occur, wheeled walkers can slip during transfers, and have the further disadvantage of occupying considerable floor space making them awkward to use in smaller rooms. Floor to ceiling poles provide good support directly adjacent to a transfer area, however, in many institutional applications, the floor to ceiling height is typically too high to allow the installation of such a device. Bed mounted support rails can be difficult to install, and have limited height thereby not providing a higher gripping point to effect an upward pull. Permanent floor mounted support rails suffer from the disadvantage of being in the way of patients who do not require them.
- Also, in the typical hospital, many different individuals with different support needs may use a particular room within a given time period. Therefore a device that is able to be installed directly beside a bed or toilet, yet easily removed would be beneficial to help meet the frequently changing needs of the various occupants of a particular room.
- The present removable floor mounted support pole device is unique in that it provides support that can be easily installed at a transfer location such as at a bed or toilet, yet it can be removed if not required, and the remaining in-floor receptacle sealed with a flush cap.
- It is the object of the invention to provide a removable floor mounted support pole for assisting elderly and disabled persons with standing from a seated surface, and providing adjacent support while moving on, to, and from a bed, bathtub, or toilet. The apparatus is designed to be installed and used in buildings with a concrete slab type floor such as in a hospital or nursing home. The support pole is designed to be deployed quickly when required and removed when not required in a given location, leaving a unobtrusive flush sealed floor receptacle.
- According to the present invention, the removable floor mounted support pole for elderly and disabled persons comprises the following two major assemblies: the support pole assembly, and the floor receptacle assembly.
- The floor receptacle is a hollow, open top, cylindrically shaped member that is designed to be installed within a cored hole in a concrete slab type floor with the aid of concrete bonding compound with its top surface flush with the surrounding floor surface. The floor receptacle is typically installed at locations where a support pole would be beneficial such as beside a bed, or toilet. The outer surface of the floor receptacle is roughened to optimize adhesion with the concrete bonding agent. A receptacle cap assembly seals the floor receptacle in a liquid tight manner when not in use. The floor receptacle also has means to secure the support pole tightly with minimal deflection during use.
- The support pole assembly provides a solid gripping surface for use by a person undertaking standing or transferring from a bed or toilet. The support pole includes taper mating surface geometry to ensure minimal movement of the pole while installed in the floor receptacle. The support pole also includes two drive pins on the bottom which are used to engage the floor receptacle cap to rotate it for removal. Further, the support pole includes a space within the top knob to store the sealing cap of the floor receptacle within the pole while the pole is installed in the floor receptacle.
- Other objects, features and versions of the present invention will become apparent from the following detailed description, which, when interpreted with the listed drawings, together disclose a preferred embodiment of the invention. It is to be understood that the drawings are intended for the purpose of illustration only, and are not intended as a definition of the limits of the invention.

By example,floor receptacle 3 may be preferably fabricated with helical annular grooves 7. Most preferably two sets of helical annular grooves 7 are used with opposite lead angles as shown to prevent the floor receptacle from rotating within a bonding agent should the surface adhesion mechanism fail. Furthermore, and to promote better surface adhesion with the bonding agent, outercylindrical surface 8 is preferably roughened in some manner such as diamond knurling.Floor receptacle 3 is preferably surface treated in a manner, such as by nickel electroplating, to prevent corrosion when installed in the typically corrosive concrete environment. - FIG. 6 is a section view “I-I”.

Therefore, whenknob 5 is rotated,inner tubular member 48, and threadedspool 43 are rotated causingthreadform 53 to engage into threaded bore 15, thereby pullingsupport pole assembly 1 tightly into the floor receptacle, and thereby giving the support pole assembly I a rigid feel while in use, and preventing inadvertent removal during use. - When
support pole 1 is removed fromfloor receptacle 3, threadedspool 43 is held captive within base stem 36 by retainingscrew 29 acting on either thetop shoulder 44 or thebottom shoulder 45 of the threaded spool. -
Top shoulder 44 andbottom shoulder 45 of threadedspool 43 have an outside diameter that is slightly less that the inside diameter of base stem 36 to permit the threadedspool 43 to float slightly from side to side to allow for any misalignment. - Although the invention has been described relating to a preferred embodiment, it should be understood that various modifications, additions, and alterations may be made to the invention by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
