Inflatable device for supporting water and beach sport
tools
Technical field of the invention
The device subject of the present invention is inflatable and can be used in the water as a supporting apparatus for sport tools, thus enabling the user to practice water and beach sports such as basketball, volleyball, tennis, etc.
State of the art
Sport tool supporting devices currently available on the market can be used for water sports only, not for beach sports. They are meant to be used for one sport only thus not allowing the practice of any other sport. Existing systems are mostly used for water polo and can only be used in swimming pools as fixed or semi-fixed systems. The patent application US-A-2001009874 describes one of these devices, showing the above mentioned incoveniences. This invention aims to overcome all the problems and disadvantages of the existing systems: it aims, indeed, to be used for a number of sports- both water and beach sports- and to create an easy-to-move device thanks to the inflatable structure which, once deflated, makes the system extremely small and, therefore, particularly easy to handle. This invention aims to create an inflatable supporting device for supporting water and beach sport tools characterized by the fact that it is formed by a three- or more-sided inflatable base structure with a central post and two
bumpers; that inflation/deflation valves are respectively located on the inflatable base structure, on the central post and on the two bumpers; that said inflatable base structure has on a side a hook for the central post that is located laterally and on the adjacent sides two hooks are located for the two bumpers; that on the central post two hooks are located for the two bumpers in such a way that, once hooked to both the base structure and the bumpers (which have, in turn, been hooked to the structure itself), the central post is positioned vertically as to the base structure; that nylon bolts are used to secure the central post and the bumpers to the base structure and between themselves; that cord-loops are located on the corners of the base structure to anchor a rope.
Another characteristic is given by the fact that the sides of the base structure are four.
Another characteristic is given by the fact that each corner of the base structure has two cord-loops.
Another characteristic is given by the fact that the rope anchored to the loops holds up the ballasts.
Another characteristic is given by the fact that, when the device is used on the beach, the rope anchored to the loops holds up a canvas filled with sand, keeping the structure steady on the beach.
Another characteristic is given by the fact that two velcro strips are located on the final stretch of the central post and some cord-loops are positioned along a common inner or outer line.
Another characteristic is given by the fact that the cord-loops located on the central post are used to fasten the net when playing either tennis or volleyball, both in the water and on the beach.
Another characteristic is given by the fact that when the device is used to play water basketball, a backboard is mounted on the central post.
Another characteristic is given by the fact that the backboard has a rectangular appendage; both the backboard and the appendage feature two couples of rectangular string-holders for two strings; the strings are inserted in the relevant holders and then secured to the above mentioned velcro strips.
Another characteristic is given by the fact that the basket is secured to the backboard rectangular appendage by inserting the provided hooks into the rectangular holders, fastening it to the rectangular appendage by means of a long string which is passed into the two couples of rectangular holders.
Another characteristic is given by the fact that a poster panel can be laid out between the bumpers.
Another characteristic is given by the fact that if between the top front of the central posts of two inflatable devices, a first inflatable anterior bar is secured and at the back part of the base structure of the two inflatable devices, a second inflatable posterior bar is secured, in order to create a goal if playing beach soccer or water polo.
Another characteristic is given by the fact that a canvas filled with sands is secured to the base structure, keeping the structure steady on the beach.
Another characteristic is given by the fact that in order to keep the goal steady, the base structure is anchored by using ballasts. Brief description of the illustrations Features and advantages of this invention will appear more evident from the description of several ways in which to build the invention given as non-limiting examples in figures 1 , 2 , 3, 4, 5, 6, 7, 8, 9, 10, 11 , 12, 13 and 14, (showing the several assembly stages) and in figures 15 and 16, showing how to use this device to create a soccer goal and a water polo goal, respectively. Detailed description of the invention Referring to figures, the inflatable device subject of the present invention consists of an inflatable three- or more-sided base structure (1), a central post (2) and two bumpers (3). Figure 2 shows an inflatable four-sided (square) base structure (1). The inflatable three- or more-sided base structure (1 ), the central post (2) and the bumpers (3) are each provided with an inflation/deflation valve (8). The inflatable base structure (1 ) is provided with a side base hook (4) for the central post (2) and two base hooks (4) located on the adjacent sides, for the bumpers (3). The central post (2) is provided with two hooks (5) for the bumpers (3). The hooks (5) on the central post (2) are located in such a way that, once hooked to both the base structure (1 ) and the bumpers (3), which have, in turn, been hooked to the structure itself, the central post (2) is positioned vertically as to the structure itself (1 ). The central post (2) and the bumpers (3) are
secured to the base structure (1 ) and between themselves with respective hooks (4 and 5) by using nylon bolts.
Cord-loops (6) are located on the corners of the base structure (1 ), possibly in couples, and they are used to anchor the ballast rope (7).
When the device is used on the beach, these cord-loops (6) are used to fasten a canvas (9) which is filled with sand and keeps the device steady on the beach.
Two Velcro strips (10) are located on the final stretch of the central post
(2) and some cord-loops (6) are positioned along a common inner or outer line (four in the figure). These cord-loops (6) are used to fasten the net
(17) when playing tennis or volleyball, both in the water and on the beach.
If used to play water basketball, a backboard (11) is mounted on the central post (2). The backboard (11 ) is provided with a rectangular appendage (12). Two couples of rectangular holders (13) for two strings
(14) are located on both the backboard (11 ) and the rectangular appendage (12). Once inserted into the rectangular holders (13), the strings (14) are then secured to the Velcro strips (10).
The basket (16) frame (15) is secured to the backboard (11 ) rectangular appendage (12) by inserting the relevant hooks (17) into the rectangular holders (13) and by fastening it to the rectangular appendage (12) by means of a long string (14) which is passed into the two couples of rectangular holders (13).
A poster panel (18) can be laid out between the bumpers (3).
Figures 15 and 16 show two inflatable devices each consisting of an inflatable base structure (1), a central post (2) and two bumpers (3). Two inflatable bars- one at the front (20) and one at the back (21)- are secured to the top front of the central post. This allows to create a goal which can be used for both beach soccer and water polo. If used for beach soccer (see figure 15), a canvas (9) filled with sand is secured to the base structure (1) in order to keep the device steady on the beach. If used to play water polo (see figure 16), base structures (1 ) are anchored by using ballasts (7). The invention, it must be noted, is not limited in use to the examples given in the illustrations, but can be modified and perfected by anyone skilled in the art without breaking patent.
This invention has several advantages and enables the user to overcome a number of problems which could not be solved if using currently available devices.
