Tub guard and extension
BACKGROUND OF THE INVENTION 
     My invention would be recognized as a child safety device, protecting and or guarding the toddler or infant from entering the bathtub. My main objective is to mentally condition the minds of the infant or toddler from becoming accustomed to entering into the bathtub without supervision. The invention is to keep the toddle or infant from falling into the tub thus avoiding any type of head trauma and or physical injury. Assessing and monitoring infant and toddler activity, it is apparent that they are psychologically very curious when exploring. Their sensory motor function is automatically turned on as they approach an area of interest. Whether they see a dripping faucet, or an object sighted near the edge or in the tub, their response is to investigate. The nature of my invention would be to discourage the toddler or infant from entering the bathtub, again avoiding physical trauma, possibly permanent, and drowning if water is present. 
     This tub guard may be constructed of rigid molded plastic tubing forming a frame, nylon netting and a support and anchoring device. The plastic tubing easily slides through tubes formed at the top and bottom of reinforced nylon netting. The horizontal tubes are joined together in the center with a &#34;T&#34; connector both at the top and bottom. Located in the center of the horizontal tubing you would connect a lateral rigid tubing to the &#34;T&#34; connections, thus giving it added support in the center of the guard. The frame is then connected to horseshoe shaped clamps at both ends. The bottom of the tubing frame lies flush to the top perimeter of the outer tub lip wall. There is a spring located within thehorseshoe shaped clamps. This allows the user to expand the horseshoe to the width of the outer tub lip wall. Upon release of the horseshoe, the spring retracts the horseshoe to the width of the tub lip wall securing the suction cups which are located at the bottom ends of the horseshoe clamps. This method would stabilize the mobility of the tub guard from both inside and outside of the tub. The nylon netting consists of a very close knit material. This will inhibit the change of the child getting their fingers caught, thus cutting off the circulation. The nylon netting is machine washable. Also, the tub guard can be quickly and easily removed when the bathtub is to be used. 
     Extension: Very similar to the assembly of the Tub Guard. The top frame end expands and attaches to the side wall or open end of the tub by a suction cup. The lower frame end is secured to the top of the tub wall by a suction cup attached to a 45° elbow fitting. 
     The invention may be used in situations where the tub enclosure is conventional and has three walls one at the back side of the tub and one at each end or in a situation where there is no wall at one or more of the ends of the tub. 
     For conventional enclosures the horseshoe shaped clamps provide support for the assembly across the entry side of the bathtub. The alternate embodiment is also able to be used in conventional enclosures where the support is provided by suction cups. The top frame member is attached to the end walls by suction cups and the lower frame member is attached to the top of the tub lip by suction cups. 
     In situations where the bathtub is configured without an enclosure wall at either or both ends another embodiment provides for support by sue of a horseshoe shaped clamp at the entry side end of the bathtub end that does not have a wall and suction cups at the backside end of the bathtub end. 
     SUMMARY OF THE INVENTION 
     The apparatus disclosed in detail below is of a form that is both practical and economical in order to promote wide use. In addition to its preferred form, it may be made in an adjustable variation or in a kit form. It comprises a rectangular shaped netting with folded over edges, secured by means, to form tube like tunnels along the top and bottom edges, and a vertical fold at the center, secured by means, to also form a tube like tunnel (at the top and bottom of the center portion of the netting a portion of netting is cut out to allow members in the top and bottom tunnels to be joined to a member in the vertical tunnel). A frame of tubular members (top and bottom horizontal members, one vertical member and two T fittings) to support the netting and keep the netting stretched vertically and also as near as possible across the full width of the opening. And a horseshoe shaped spring loaded clamp support means. 
     The outer ends of the top and bottom horizontal members are used to join the frame to the support means. At the mid horizontal points of the top and bottom horizontal members, T fittings are used to join the mid vertical member to the top and bottom horizontal members. The support means used are two spring loaded horseshoe shaped clamps with suction cups, one situated at each lower horizontal end of the frame. In addition, the horizontal ends of the frame may have tubular extensions with suction cups for added strength and stability. 
     In a standard tub installation there would be a wall at each end of the tub to be available to prevent entry. In the event either or both walls do not exist an extension of the apparatus may be installed.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     In FIG. 1 there is shown the Tub Guard and Extension apparatus of the present invention comprising a rectangular shaped netting FIG. 2 (1) with folded over edges, secured by means to form tube like tunnels along the top and bottom edges, (2) and a vertical fold at the center, secured by means, to form a similar tube like tunnel (3). At the top and bottom of the center portion of the netting a portion of netting is cut out (4) to allow the frame members (6 and 7) to be joined to other members or fittings (5). A frame is formed of the tubular members (top and bottom horizontal members (6) and one vertical member (7)) to support the netting and keep the netting stretched vertically and also as near as possible across the full width of the tub opening. Various fittings (5) and support means FIG. 3 (8) with connection posts (9) and suction cups (10) are used to secure the apparatus to the tub. This embodiment may be used whether or not the tub enclosure has walls at either or both ends of the tub. 
     A second embodiment is shown in FIG. 4 where a rectangular shaped netting (11) with folded over edges is secured by means, to form tube like tunnels along the top and bottom edges (12). A frame is formed of tubular members (top horizontal members (13) and bottom horizontal member (14). The top horizontal member having slideable extensions (15) with suction cups at both ends to secure the frame to the bathtub enclosure walls. The bottom horizontal member may be shaped with elbows (16) and suction cups at both ends to secure the frame to the top of the bathtub. This embodiment may only be used for a conventional tub enclosure where there are walls at both ends of the bathtub. 
     In the vent the tub installation does not have a wall at either or both ends to prevent entry an extension may be installed comprising a shorter version of the above described apparatus as shown in FIG. 4 comprising a rectangular shaped netting (11) with folded over edges, secured by means, to form tube like tunnels along the top and bottom edges (12). A frame is formed of tubular members (top horizontal members (13) and bottom horizontal member (14). The top horizontal member having a slideable extension (15) with suction cup to secure the frame to the bathtub back wall. The bottom horizontal member may be shaped with an elbow (16) and a suction cup to secure the frame to the top of the tub. Both the top and bottom horizontal members are secured to a support means (8) with connecting posts (9). Suction cups (10) on the support means are used to secure the extension to the end of the bathtub. The support means (8) is positioned to clamp to the end of the tub. 
     From the foregoing description it will be apparent that modifications can be made to the apparatus without departing from the teaching of the present invention. Accordingly, it is distinctly understood that the invention is not limited to the preferred embodiment but may be embodied and practiced within the scope of the following claims.
