     BACKGROUND INFORMATION 
     1. Field of the Invention 
     The present invention relates to grab bars, and more particular to a rapidly mounted, modular, universal grab bar with one piece molded mount with integrated accessories. 
     2. Background Information 
     A handrail is a rail that is designed to be grasped by the hand so as to provide stability or support. Handrails are commonly used while ascending or descending stairways in order to prevent injurious falls. They can also be called banisters and balustrades. Handrails are typically supported by posts (or balusters) or mounted directly to walls. Other common handrail applications include handrails surrounding balconies. 
     A further common handrail application is forming a barre (also called a bar), which serve as training aids for ballet dancers. A barre is a stationary handrail that is used during ballet warm up exercises. The term also refers to the exercises that are performed at the barre, as well as that part of a ballet class that incorporates barre exercises. 
     A further common subset of handrails is known as grab bars. A grab bar is commonly identified as a bar forming a handhold which is designed to help people with disabilities. Grab bars are commonly found in accessible restrooms where they help people get in and out of wheelchairs and walkers. Grab bars can also be installed in full bathrooms to help people navigate the bathroom. In some homes, grab bars are installed in many locations around the house, anticipating a variety of potential needs. Although there is no precise limit or defining length, a grab bar is generally a shorter type hand rail. In fact in most applications a grab bar is a hand rail having only two supports. 
     There are a number of hand rail and grab bar systems illustrated in the prior art. For example U.S. Pat. No. 6,932,328 assigned to Constructions Specialties, Inc. discloses a rail and wall support installation includes an adapter which mechanically couples a wall support having a rotatable locking cam portion to an undercut groove on the rear of the rail. The adapter serves both as a mechanical attachment point for the rail to a wall support and to transfer the cam action of the locking cam portion to the rail. U.S. Pat. Nos. 6,508,458 and 6,270,058 also assigned to Constructions Specialties, Inc. discloses a similar systems. 
     U.S. Pat. No. 4,650,164 describes handrail system for suspending a handrail spaced from a supporting structure such as a wall with internal clamping brackets providing a trim appearance. The handrail system includes an elongated generally cylindrical rail body having a tubular wall of generally uniform wall thickness surrounding a hollow interior region. Slots are formed in the tubular wall along a line parallel with the rail axis. A rail support assembly connects each slot to the supporting structure. Each rail support structure includes a pair of similar stamped and formed metal brackets. Each bracket includes a flat body and an arm of reduced size extending from the body at an angle and defining a pair of rail engaging shoulders on the body. The arms are inserted through a slot into generally side-by-side relation within the hollow interior region with the shoulders extending beyond the slots. A threaded fastener engages the support structure and the brackets for clamping the bodies together and separating the arms to clamp the interior of the rail and hold the rail against the shoulders. 
     U.S. Pat. Nos. 3,433,360 and 3,343,811 disclose handrail mounting systems. Other relevant teachings can be found in U.S. Pat. Nos. 3,306,641, 3,223,371, 2,886,278, and 2,807,834. 
     Many currently available commercial grab bar products are configured with a flange mount that typically utilizes a two or three bolt-mounting pattern. When vertically mounted, these patterns provide for typically only one fastener, at best, on each end to align with a wall stud. If horizontally mounted, engaging a stud with a fastener is only possible if the length of the grab bar is such that it agrees with the spacing of the wall studs, and more often than not, the spacing does not agree. When anchoring to a wall stud is not possible, current grab bar manufacturers recommend using special fasteners such as a Wingits™ brand specialty fasteners and similar fasteners, or toggle bolts or the like. Wingits™ are very expensive and labor intensive. Toggle bolts are not as strong as anchoring to a stud. Consequently wall anchoring of the supports to a stud is preferred. 
     Thus, for optimum mounting strength, the length of the grab bar must match the spacing of the wall studs so that a fastener can be secured directly to a wall stud. Current commercial grab bar lengths are not adjustable or selectable. As noted above, many if not most of the available grab bar lengths do not agree with stud spacing. Installation is more involved, more time consuming, more labor intensive and more expensive when using special fasteners such as Wingits™ type fasteners, which are necessary when, anchoring to a wall stud is not possible. 
     Despite the plethora of handrail and grab bar systems developed there remains a need for a cost effective rapidly mounted, modular, universal grab bar and handrail system. There is a need for an easy and cost effective rapidly mounted, modular, universal grab bar and handrail system and easy back to back grab bar mounting. 
     The inventors have addressed some of these deficiencies of the prior art with the rapidly mounted, modular, Universal Grab Bar and Handrail System set forth in U.S. Pat. No. 9,181,709, which issued Nov. 10, 2015 and which published as U.S. Publication Number 2013-0167454, which patent and publication is incorporated herein by reference. The present invention is directed to improvements in the design of the type of grab bar disclosed in the &#39;709 patent to improve the economic advantage and commercial applicability of the design.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The present invention can easily be described in connection with the front mounted, modular, universal grab bar system  10  shown in the figures that may be mounted to a wall on studs. Further discussion on the mounting of this type of system is found in in U.S. Pat. No. 9,181,709 entitled “Universal Grab Bar and Handrail System” and which published as U.S. Publication Number 2013-0167454, which patent and publication is incorporated herein by reference. The system  10  includes a plurality of one piece molded mounts or wall supports  20  shown in greater detail in  FIGS. 2A-F  and  3 . Each wall mount  20  can be easily molded of plastic, or other material of suitable strength, and can include any ornamental outer configuration and finish as desired. The cored circular cross section shown for the mounts  20  is believed to be the easiest from a manufacturing standpoint. Each wall mounted support  20  includes a rail member recess  26  or through hole extending generally perpendicular to a longitudinal axis of the mount  20 . The rail member recess  26  is in the form of a rail member encircling through-hole opening and is aligned with a central fastener opening  36  that extends generally along the longitudinal axis of the mount  20 . The central fastener opening  36  is stepped to allow for receipt and rotation of the head of a central faster  24 . 
     In general, each wall support or mount  20  is secured to a wall stud with a fastener  24 , wherein each central fastener  20  includes a drive head and is associated with a wall mounted support or mount  20  for securing each mount  20  to the wall through the central fastener  24 . The central fastener  24  may be any number of conventional fasteners, such as a steel fastener with a hex or Allen head drive head and a wood engaging end for use with the wood studs of the walls. Each molded mount  20  is, at least at time of initial wall attachment, rotationally adjustable about the central fastener  24  to allow for proper alignment with other laterally spaced wall supports  24  of the system or assembly  10 . 
     The grab bar system  10  includes at least one stock rail member  12  forming the grab bar. The rail member  12  may be interchangeably referenced as a grab bar  12 , rail  12 , bar  12  or similar term herein. Each rail member  12  is received within rail member recesses  26  of the mount  20 . The central fastener  24  of each wall support  20  extends perpendicular to the axis of the rail member  12 . The stock rail member  12  can be easily formed of common metal bar stock  12  (or plastic stock) which can be easily cut to length by the user for a designated length. The rail member  12  can have numerous decorative finishes as desired (such as a knurled surface for improved grip) and the material selection is dependent only upon the strength requirements for the grab bar  12 . For example, plastic may be utilized for certain implementations of the rail  12 , such as the glow in the dark application. The rail member  12  is shown used with two mounts  20 , but three or more mounts  20  could be implemented with a single section or piece of rail member  12 . 
     Molded, rail member end caps  14  can be used at distal ends of the grab bar rail member  12 . The molded end caps  14  can take a variety of decorative shapes and be designed for accessories as discussed below in connection with  FIGS. 7-11 . The mounts  20  include set screw holes  30  for receipt of set screws there through to engage with the hand rail member  12  to rotationally and axially secure the hand rail member  12  in position. The pair of set screw holes  30  are positioned in the front of the mount  20  for ease of assembly and to have the set screw be covered by the molded central fastener end cap  22 . Screws need not be in each opening  30  or even at each mount  20 , as one screw per mount  20  or even per rail member  12  may be sufficient. 
     The molded one piece central fastener end cap  22  is provided for sealing the central opening  30  of the wall supports or mounts  20 . The end cap  22  may include an annular array of fingers with locking projections that engage an associated undercut in the molded wall support  20 . The cap  22  design having a secure snap fit coupling or other connections could be implemented. The cap  22  covers the fastener  24  and the set screws such that there are no exposed fasteners providing for a tamperproof construction that is advantageous particularly in commercial applications. The rail  12  also covers the fasteners  24 , as understood. 
       FIGS. 1 and 4A  and B are included to demonstrate a typical grab bar assembly of the present invention, sold under the mark SMARTBAR™ assembly  10  of which the one piece molded mounts  20  are a key component. In its simplest form the assembly consists of the following: a bar  12 ; a bar cap  14  at each end of the bar  12 ; a pair of mounts  20 , each mount with a thru hole  26  that encircles the bar  12 ; a pair of mount caps  22 ; two central fasteners  24 , one fastener  24  for securing each mount  20  to a wall surface or structure; underneath each mount cap  22  are setscrews in holes  30  (although less set screws may be used than there are holes  30 ). Once the bar  12  is in the desired location, these setscrews secure the bar  12  from moving in the direction of the bar axis and also prevents the bar  12  from rotational movement. 
       FIGS. 2A-F  and  3  illustrates the features of the new one piece molded mount  20  with the following characteristics: a Bar thru hole  26  which encircles the bar  12  so that bar length and the mounting distance between mounts  20  are non-critical; the mounts  20  are injection moldable; the fastener head mounting surface and the base of the mount can be sealed with O-rings in groove  32  so that the installation can be made waterproof which is highly desirable in wet or corrosive environments; single point fastening via fastener  24  through hole  36  to reduce installation complexity and labor costs; moldable from metal replacement engineered polymers. Note the cored out bottom including ribs to the material forming the central mounting srew hole  36 . Features of the mount  20  include that the mount encircles the bar  12  via holes  26 , allowing the bar  12  to be positioned anywhere between the mounts  12 . This eliminates the necessity of precise bar length and mount  20  location such that a precise length of the bar  12  is not required and precise location of the mounting holes for mounts  20  are not required. Tamper resistance is another feature of the assembly  10  as no access to any fasteners  24  or set screws are visible due to caps  22 . The single fastener  24  per mount  20  yields simple mounting. The mounts are preferably molded from reinforced thermoplastic polymer (a metal replacement engineered plastic) and the design yield a minimum number of parts required. The mounts are internally cored for material savings with ribs for strength. The coring further provides for an ease of production as the molding cycle time is greatly reduced without the core. The mount  20  material and associated hardware are highly corrosion resistant. The design includes a long engagement with the mounting fastener  24  (i.e. the head of the fastener is spaced from the wall and spaced from the end of the mount  20 ) for additional support and strength. The sealed mounting with O-rings in groove  32  on the mounting surface allows for sealed applications such as in bathrooms. 
     The system mounts  20  can be used with or without a flange  34  at the base of the mounts  20 . The underside view is shown to highlight the Mount O-ring seal via O-rings in grooves  32  which is a highly reliable method of sealing without the mess and disadvantages of caulk or silicone. A similar seal may also be included on the flange  34 , if used. 
     An effective, efficient and advantageous force transferring configuration is exhibited in the system  20  wherein the rail member recesses  26  of the wall mounted supports  20  encircle the rail member  12  and are configured to align the rail member  12  with the associated central fasteners  24 . This design provides an efficient load transfer in use from the rail member  12  to the support  20  to the fastener  24  to the wall. Further the positioning of the head of the fastener  24  more than halfway between the end of the mount  20  and the rail member recess  26 , as shown, provides the structural support of the central fastener  24  to the system  10  to resist bending moments. 
     With front mounting, each wall support  20  is fastened with a single centralized fastener  24  from the front through the wallboard or the like and into a stud. As noted above, the wall support  24  has a rail member recess  26  in the form of a through hole, perpendicular to its axis, with a diameter sufficient for the hand rail member  12  to pass through (generally with close tolerances to avoid visible gaps). Each of the two (or more) wall supports  20  can be located on a stud regardless of the stud spacing. A fastener  24  is inserted through the front end of the fastener opening  36  of each wall support  20 , and engaged into the wall and stud. Typically the fastener  24  can be driven directly into the wooden stud with no pre-drilling required. A separate conventional metal stud fastener  24  would be utilized for metal stud containing walls. 
     The required length of hand rail member  12  can be measured, based on the distance between the wall supports  20  and the desired overhang, and the stock material for the member  12  then cut to length. The cut member  12  is inserted through both (or more) wall supports  20  via openings  26  and secured with a set screw fastener in one or more wall supports  20  via openings  30 . A predetermined length of grab bar  12  may also be used with the grab bar  12  centered within the wall secured mounts  20 , as the predetermined lengths of grab bar may make it easier to include some of the integrated accessories discussed below. 
     The present invention provides a simple to install grab bar system  10  that can be adjusted for any length and wall stud spacing and for any desired angle. The ease of cutting the bar stock  12  to length minimized the number of components an installer must carry for any job. The single point fastening of mounts  20  provides for rapid attachment of the system  10  and for easy angular adjustment of a wall support  20  relative to an adjacent support  20 . The present system  20  provides that accurately holding the mounting distance between wall supports  20  is not required since the supports  20  are separate loose pieces that are individually mounted. The present system  10  does not require a multiple-fastener mounting pattern (typical grab bars have 3 fasteners per end—6 total). Further the system  10  can be easily implemented with hex head fasteners and hex head fasteners can be installed with a drive socket rather than a screw driver. It&#39;s physically much easier to install a fastener with a ratchet socket wrench than a screwdriver. With hex head fasteners, much higher tightening torque can be achieved which results in greater holding force. Front mounting, rear mounting and back to back mounting configurations are all easily provided for without special tools or fasteners. 
     The system  10  provides a single versatile, product that&#39;s simple to install and the finished installation are esthetically pleasing. Further the system  10  provides for no exposed fasteners. The system  10  provides for unlimited lengths are possible by simply connecting bars together (appropriate couplers are shown in U.S. Pat. No. 9,181,709). The system  10  provides for significant reduction in installation labor with single point fastening. The system  10  provides for unrestricted mounting capabilities (horizontal, vertical, at any angle). The system  10  preferably utilizes stock rail members  12  cut to length and inexpensive standard fasteners instead of high cost specialty fasteners. 
       FIG. 6  illustrates the injection moldable metal replacement material used in the mounts  20 . As discussed in further detail bellow grab bar  12  can be equipped with the following functionalities: Glow in the Dark grab bar; Lighted grab bar; Wireless speaker grab bar; Radio grab bar; Scent emitting grab bar; Heated grab bar and Vibrating grab bar. Where appropriate these integrated grab bar accessories can be actuated (switching on-off) by a number of different sensing technologies such as Motion-detecting (ultrasonic and microwave), Heat-sensing (infrared), Sound-sensing (acoustic), Touch sensing (capacitance and resistive), Light sensing (photocell), and Passive infrared sensing (occupancy). Mechanical switches can also be employed. 
       FIG. 7  demonstrates the aspects of the glow in the dark grab bar assembly  10 .  FIG. 7  illustrates the grab bar or rail member  12  with bar caps  14 ′. The mounts are not shown. Here the bar caps  14 ′ can be made from glow in the dark material. It is also possible that the stock rail material  12  could be formed of glow in the dark material. Phosphorescence is the term for the process in which energy absorbed by a substance is released relatively slowly in the form of light. This is the proposed mechanism used for “glow-in-the-dark” materials forming the molded caps  14 ′ (and possibly the bar  12 ) which are “charged” by exposure to light. Unlike the relatively swift reactions in fluorescence, such as those seen in a common fluorescent tube, phosphorescent materials “store” absorbed energy for a longer time, as the processes required to re-emit energy occur less often. For this phosphorescent-based purpose, strontium aluminate may be used as a coating pigment, or preferably as an additive to the plastic forming the molded caps  14 ′ (or the bar  12 ). When added to the plastic, the strontium aluminate may be coated with a lubricant due to the hardness of the strontium aluminate particles. Other phosphorescent particles may be utilized. This construction provides illumination in dark conditions while eliminating the need for a powered light source. Additionally the molded mount caps  22  and the molded mounts  20  can be made from glow in the dark material. 
       FIG. 8 —Lighted Grab bar assembly  10 . The lighted grab bar  12  in this configuration is a device that will illuminate when activated by an external action such as touching the bar  12 . Activation of the electronic aspects of the grab bar assemblies  10  of the present invention can be accomplished by any of the following known sensing methods/switches: Touch sensing of the rail  12  (via capacitance and resistive sensing), Motion-detecting (via ultrasonic or microwave sensors), Heat-sensing (via infrared sensors), Sound-sensing (acoustic sensors), Light sensing (photocell sensing—Note for the lighted grab bar the light sensing will turn on the lights  44  of the system  10  when sensing the light is below a given threshold rather than above), Passive infrared sensing (aka proximity or occupancy sensors), and Built in the bar switch i.e. tape switch or membrane switch. As the rail member  12  is a hollow tube with open ends, a device or mechanism with (or without a battery pack  40 ), etc. can be housed inside the bar  12 . This is an advantage over current grab bars that have flanges that fasten to the wall. There is no convenient access to insert components and/or batteries into the grab bar. 
     The grab bar power source can be the battery pack  40  (i.e. series of batteries  40  in a carrier such as in a common flashlight), but it can also be external as in an cord which plugs into a common household receptacle.  FIG. 8  illustrates the bar  12  portion of the grab bar assembly  10 . Contained within the bar  12  are a circuit board with the appropriate circuitry shown at  42 , batteries  40  and a light source  44  (such as LED&#39;s) adjacent at least one accommodating bar cap  14 ″. The accommodating bar cap  14 ″ will be formed to accommodate the LED light and will be formed as transparent or translucent member. The bar cap  14 ″ may include conventional light dispersion features/optics to better disperse the light. Any of the above sensing technologies can be used to activate and deactivate the light source  44  (LED&#39;s). Deactivation can also be accomplished by a timer circuit incorporated on the circuit board  42 . 
       FIG. 9 —Wireless Speaker Grab bar: The bar  12  of this embodiment houses an audio speaker  54  which can be utilized in conjunction with any wireless technology such as Bluetooth via controller  52 .  FIG. 9  illustrates the bar portion  12  of the Grab bar assembly  10 . Contained within the bar  12  is a controller  52  including generally a circuit board and wireless receiver, batteries  40  and a sound source (speakers  54 ) adjacent a bar cap  14 ′″. The bar cap  14 ′″ is perforated to assist in the dissemination of sound. Any of the above sensing technologies can be used to activate and deactivate the sound source (speakers  54 ). Deactivation can also be accomplished by a timer circuit incorporated on the circuit board. The grab bar power source can also be external as in plugging into a common household receptacle. 
       FIG. 10 —Radio Grab bar: The bar  12  of this embodiment houses a Radio  62 .  FIG. 10  illustrates the bar portion  12  of the grab bar assembly  10 . Contained within the bar  12  is the radio  62  with (speakers not identified separately) adjacent a bar cap  14 ″&#39;. Any of the above sensing technologies can be used to activate and deactivate the radio. Deactivation can also be accomplished by a timer circuit incorporated on the circuit board. The grab bar power source can also be external as in plugging into a common household receptacle. The radio components may be wirelessly coupled to an external controller to allow the user to adjust the radio (adjust the volume and change the radio station which is tuned in and change the format (e.g., AM, FM or Satellite). Alternatively controls may be provided or accessible through an access opening in the bar  12 , but such a design requires a specific bar to be used or a separate opening cutting step to be used, such that wireless coupled controls are preferred. 
       FIG. 11 —Scent Emitting Grab bar: This version provides the capability of emitting a pleasing scent into the environment (e.g., aroma therapy) while concealing the mechanism inside the bar  12 .  FIG. 11  illustrates the bar portion  12  of the Grab Bar assembly  10 . The bar  12  can house a scent emitting device  72  similar to those found in GLADE PLUG IN® and FABREZE NOTICEABLES® brand air fresheners. Contained within the bar  12  is the scent emitting device  72  (often a heating unit), batteries  40  and the appropriate scent emitting material  74  (often a solid, semisolid or liquid in a container that cooperates with the device  72 . A timer circuit incorporated on the circuit board or controller of the unit  72  can expel scent at adjustable intervals or continuously. The scent compound  74  can be replenished via the bar cap  14 ′″. The perforated bar cap  14 ′″ will assist in emitting and disseminating the scent. The grab bar power source can also be external as in plugging into a common household receptacle. 
     Not shown in  FIG. 11  is a Solid Room Freshener type. The bar caps  14 ′″ can be configured to hold replaceable solid or semi-solid room air fresheners such as GLADE® Solid Air Freshener. No power source or circuit board is required for this type of scent emitting unit. 
       FIG. 12  discloses a Battery Powered Liquid (or powder) Dispenser grab bar system  10  according to one aspect of the present invention wherein the system  10  will store and dispense a liquid (or powder) such as soap, body wash, lotion, hand cleaners etc. when activated by an external action such as touching the bar  12 . Activation can be accomplished by any of the following sensing methods: Touch sensing, Motion-detecting, Passive infrared sensing, or a Built in the bar switch i.e. tape switch, membrane switch. The bar  12  of this embodiment can house the batteries  40  for powering the dispenser, a pump  82  for dispensing, and a liquid reservoir  74  (refillable via the top cap  14 ), and a modified lower bar cap  86  having a dispending nozzle therein controlled by pump  82 . The system  10  is well suited for a bathtub to yield a safety grab bar system with integrated dispenser for soap, conditioner, body wash or the like. Hotels and health clubs represent users of this embodiment. 
     The embodiment of  FIG. 13  is a Battery Powered Rotary Sprayer grab bar assembly  10 . The embodiment is substantially an inverted version of the embodiment of  FIG. 12  wherein the dispenser end cap  86  (now on the top of the assembly  10 ) is replaced formed in the form of a rotary or radial directed sprayer/end cap  96 . The construction of spraying dispensing nozzles is known in the art and not described herein in detail. Essentially the device that will store and spray a liquid, such as a shower cleaner in a rotary pattern to clean the interior of a shower. It can be activated by any of the above methods, or from a remote controller. This embodiment, with remote control activation, is particularly useful for industry applications for cleaning showers (i.e. hotels, hospitals, health clubs and the like). When it is time to clean and disinfect the shower which incorporates the grab bar  10  the worker activates the sprayer (via remote or the like) and the system will automatically spray the shower or bath area. The worker can then typically wait an allotted time (for example, while cleaning the remainder of the room) and wipe down the shower/bath area after the prerequisite amount of time. It almost provides a self cleaning and disinfecting bath/shower area, and the system still provides a useful grab bar for safety applications by other users of the bath. 
       FIG. 14  illustrates a Non-Powered Liquid/powder Dispenser grab bar assembly  10  according to the present invention in which the device will store and dispense a liquid or powder such as soap, body wash, lotion, hand cleaners etc. when activated by an external manual action such as moving a lever or depressing a plunger in the dispenser head/bar cap  106 . The details of this type of dispenser are generally known in the art and not described in detail herein other than they are designed to fit into the rail member  12  as shown. 
     Another alternative is a heated grab bar, not shown, which provides the capability of heating the bar. In areas that are cold or wherever a warm hold is required, the bar can house an electric heater. It can be powered by battery or externally as in plugging into a common household receptacle. Another alternative integrated accessory is a Vibrating grab bar, not illustrated. This version provides the capability of vibrating the bar such as in a hand held massager. It would offer therapeutic benefits to the user. 
     It will be apparent to those of ordinary skill in the art that various modifications may be made to the present invention without departing from the spirit and scope thereof. The scope of the invention is not to be limited by the illustrative examples described above.
