I. Field of the Invention
The present invention relates generally to the field of recreational activities and more particularly to a floatation apparatus.
II. Description of the Related Art
Present recreational floatation devices are typically a single elongated piece manufactured of Styrofoam or other suitable material that floats. Other recreational floatation devices are inflatable. While these devices are suitable for use in pools and other calm water, their use in the ocean, where waves are present is typically not desirable. The single piece floatation devices offer the disadvantage that as waves pass by the device, the device tends to be carried along with the wave or be capsized. These devices do not offer any locations through which the water can pass and leave the device in a relatively stable position. As such, lying out or calmly floating on rough water can be interrupted by the presence of waves.
In general, the invention features a floatation apparatus. The apparatus has a generally square frame having several cross ropes or chains onto which individual floating cylinders are attached. The frame is typically PVC pipes with elbows at appropriate connection sections. In another embodiment, chains can be used as the frame. Additional floatation cylinders are added at the front and back for further cushioning and floating power. The apparatus includes a pull rope or chain so that the apparatus can be pulled or connected to another apparatus to create a longer floatation device or, if propped, a lounger. By having several separate floatation cylinders, the apparatus better handles the water by allowing water to pass through the spaces in between the floatation cylinders while still providing floatation. In particular, as waves in the ocean pass over the apparatus with a user on the apparatus, the apparatus better maintains an upright orientation by allowing the force of the waves pass through the spaces.
In general, in one aspect, the invention features a floatation apparatus, including a generally polygonal frame having an upper tube parallel to a lower tube, and two parallel side tubes, a plurality of generally adjacent and parallel floatation cylinders located within the frame, generally perpendicular to the side tubes and parallel to the upper and lower tubes, each cylinder having a hollow center along a longitudinal axis and an elongated connection tie connecting each of the floatation cylinders to the frame.
In one implementation, the apparatus further includes an additional floatation cylinder surrounding the upper tube.
In another implementation, the apparatus further includes an additional floatation cylinder surrounding the lower tube.
In another implementation, the elongated tie is a band connected end to end forming a continuous loop that is disposed through the hollow center of each floatation cylinder and looped around each of the side tubes.
In another implementation, the apparatus further includes an elbow located at each corner of the frame.
In another implementation, the apparatus further includes an elongated rod located within the each of the side tubes.
In still another implementation, the side tubes comprise a plurality of holes aligned with an adjacent hollow center of an adjacent floatation cylinder.
In yet another implementation. the elongated tie is a rope connected end to end forming a continuous loop located within the hollow center of each floatation cylinder and through a corresponding hole on each of the side tubes, and further looped around the elongated rods within the side tubes.
In another implementation, the hollow cylinders are closed cell polyethylene foam.
In another aspect, the invention features a recreational system, including a first floatation apparatus, including, a generally polygonal frame having an upper tube parallel to a lower tube, and two parallel side tubes, a plurality of generally adjacent and parallel floatation cylinders located within the frame, generally perpendicular to the side tubes and parallel to the upper and lower tubes, each cylinder having a hollow center along a longitudinal axis and an elongated connection tie connecting each of the floatation cylinders to the frame, a second floatation apparatus connected to the first floatation apparatus, the second apparatus including a generally polygonal frame having an upper tube parallel to a lower tube, and two parallel side tubes, a plurality of generally adjacent and parallel floatation cylinders located within the frame, generally perpendicular to the side tubes and parallel to the upper and lower tubes, each cylinder having a hollow center along a longitudinal axis and an elongated connection tie connecting each of the floatation cylinders to the frame.
In one implementation, the first and second apparatuses are hingably connected to one another at first ends of the frames by ties.
In another implementation, second ends of the frames are connected to one another by elongated ties.
In another implementation, the elongated ties are adjustable to fix an angular orientation between the two apparatuses.
In another implementation, the elongated ties adjust to a length such that the apparatuses are arranged in an angular orientation sufficient to allow a user to sit in a lounged position.
In another implementation, the system further includes a planar adjustment plate connected to ends of each elongated tie.
In still another implementation, the planar adjustment plate includes three holes, the elongated ties being knotted at one end and threaded through a first hole through an upper surface of the plate, through a second hole through a lower surface of the plate and through a third hole through the upper surface of the plate.
In yet another implementation, the plate is triangular.
In another implementation, the ties are nylon rope.
In another implementation, the elongated ties are nylon rope.
In still another aspect, the invention features a recreational floatation apparatus, including a rectangular tubular frame, means for floating the frame located within the frame, and means for retaining the means for floating the frame within the frame.
One advantage of the invention is that waves can pass through the several openings present in the apparatus.
Another advantage of the invention is that it can be converted to a lounger.
Other objects, advantages and capabilities of the invention are apparent from the following description taken in conjunction with the accompanying drawings showing the preferred embodiment of the invention.
Referring to the drawings wherein like reference numerals designate corresponding parts throughout the several figures, reference is made first to
Each apparatus 100, 200 typically includes an elongated connection tie 130, 230 connecting each of the floatation cylinders 125, 225 to the respective frame 105, 205. The elongated connection ties 130, 230 are discussed in further detail in the description below. In addition, each apparatus 100, 200 includes an additional floatation cylinder 135, 235 surrounding the upper tubes 110, 210 and an additional floatation cylinder 140, 240 surrounding the lower tubes 115, 215. Since it is desirable that the apparatuses 100, 200 alone and combined as the system 300, float, the cylinders are a material that is capable of floating, light weight and resistant to absorbing water. In a typical embodiment, the cylinders are closed cell polyethylene foam. It is understood and appreciated that the cylinders can be other materials in other embodiments.
The apparatuses 100,200 typically further include an elbow 145,245 located at each corner of the frames 105, 205. It is appreciated that the elbows 145, 245 connect all of the respective tubes together to form the frames 150, 205 that are typically rectangular. It is further appreciated that although other shapes are contemplated, the rectangular shape allows a user to lie on either apparatus 100, 200 individually as a single floatation device or as shown in the figure as a lounger. Different lengths of the apparatuses 100, 200 are further contemplated in other embodiments to accommodate users of varying heights. In a typical embodiment, the frames 105, 205 (including all respective tubes and elbows) are a light weight and durable material such as plastic. For example, the frames 105,205 can be poly vinyl chloride (PVC). Suitable adhesive or other glues can be used to connect together the constituent pieces of the frames 105, 205.
