1. Field of the Invention
The present invention relates to collapsible structures, and in particular, to collapsible floating assemblies which offer multiple uses, and which may be twisted and folded to reduce the overall size of the assembly to facilitate convenient storage and use.
2. Description of the Prior Art
Collapsible objects have recently become popular with both adults and children. Examples of such collapsible objects are shown and described in U.S. Pat. No. 5,038,812 (Norman), U.S. Pat. No. 5,467,794 (Zheng) and U.S. Pat. No. 5,560,385 (Zheng) in the form of collapsible structures. These structures can be used as play structures, shelters, tents, and storage structures, among other uses. These structures may be twisted and folded to reduce the overall size of the structures to facilitate convenient storage and use. As such, these structures are being enjoyed by many people in many different applications.
Other examples of collapsible objects include blanket, mat and floating assemblies as illustrated in one or more of U.S. Pat. No. 6,073,283 (Zheng), U.S. Pat. No. 6,170,100 (Le Gette et al.), U.S. Pat. No. 6,343,391 (Le Gette et al.) and U.S. Pat. No. 6,908,353 (Zheng). These assemblies can be used as blankets, floor mats, and floating mats. These blankets and mats may be twisted and folded to reduce the overall size of the blanket or mat to facilitate convenient storage and use.
It is an object of the present invention to provide a floating assembly that offers increased flexibility in use.
In order to accomplish the objects of the present invention, there is provided a floating assembly for suspending a person on water, the floating assembly having a sheet material that defines the periphery for the floating assembly. A plurality of floatation devices are attached to the periphery. The plurality of floatation devices includes a top floatation device that forms a head pillow, a first side floatation device, and a second side floatation device positioned opposite to the first side floatation device. A first arm space is defined between the top floatation device and the first side floatation device, and a second arm space is defined between the top floatation device and the second side floatation device.
In accordance with another embodiment of the present invention, the periphery can be defined by a foldable frame member that has a folded and an unfolded orientation.
The following detailed description is of the best presently contemplated modes of carrying out the invention. This description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating general principles of embodiments of the invention. The scope of the invention is best defined by the appended claims.
Referring to
The frame member 26 may be provided as one continuous loop, or may be a strip of material connected at both ends to form a continuous loop, or can be a strip of material having opposite ends that are adjacent to (but not connected to) each other. The frame member 26 is preferably formed of flexible coilable steel, although other materials such as plastics may also be used. The frame member 26 should be made of a material which is relatively strong and yet is flexible to a sufficient degree to allow it to be coiled. Thus, the frame member 26 is capable of assuming two positions, an open or expanded position such as shown in
In addition, a protective covering 28 can be provided to cover the frame member 26. The protective covering 28 can be the same as that which is described in U.S. Pat. No. 5,845,697 to Zheng, whose entire disclosure is incorporated by this reference as though set forth fully herein. The protective covering 28 can be effective in preventing the metallic frame member 26 from rust and damage due to its anticipated exposure to water.
Sheet material 30 extends across the interior space defined by the sleeve 24, and is held taut by the frame member 26 when the sheet material 30 is in its open position. The term “sheet material” is to be given its broadest meaning and should be made from strong, flexible yet lightweight materials and may include woven fabrics, sheet fabrics, meshed fabrics or even films. The sheet material 30 can be water-resistant and durable to withstand the wear and tear associated with extended use, and rough treatment by adults and children. The sheet material 30 can also allow water to pass therethrough (e.g., such as a meshed material).
As illustrated best in
A plurality of floatation devices 50 are provided in spaced-apart manner about the peripheral edge 22. Each floatation device 50 includes a separate floatation sleeve 32 that can be stitched to the sleeve 24 by a stitching 40. Thus, the floatation devices 50 can be permanently attached (e.g., by stitching 40, welding or fusing), or removably attached (e.g., by hooks, VELCRO™ pads, etc.), to the peripheral edge of the sleeve 24. The floatation device 50 can be embodied in any desirable structure, including but not limited to one or more foam pieces, or one or more inflatable bags 42, housed inside the floatation sleeve 32.
As an alternative, the sleeve 32 can be omitted and the inflatable bag 42 can be stitched directly to the sheet material 30 or the sleeve 24.
The floatation devices 50 are spaced-apart about the peripheral edge 22 so as to define an open space between each pair of adjacent floatation devices 50. In particular, at least four separate floatation devices 50w, 50x, 50y, 50z are provided to define four separate open spaces 60, 62, 64 and 66 between each other. Each of these spaces 60, 62, 64, 66 is provided along the peripheral edge 22, and each is adapted to receive part of a human limb when a user is lying on the sheet material 30. For example, when the user lies on the sheet material 30 with the head resting on the top floatation device 50x (which can function as a head pillow), part of each of the user's arms can extend through one of the spaces 60 and 62, and part of each of the user's legs can extend through one the spaces 64 and 66, which are separated by a bottom floatation device 50w.
In use, the user can inflate the floatation devices 50 and then place the assembly 20 into a body of water (e.g., swimming pool, beach, lake, etc.). The user can then climb on to the top surface of the assembly 20 and then lie on the assembly 20 as the assembly 20 floats on the water, as shown in
To store the assembly 20, the user first deflates the floatation devices 50 so that the entire assembly 20 can have a generally flat profile. The assembly 20 can then be folded and collapsed into a compact configuration for storage, as illustrated in
In addition, a retaining member or strap 74 (shown in
The assembly 20 can be expanded again by opening the coiled frame member 26. The bias and resiliency of the frame member 26 will cause the frame member 26 (and the attached sheet material 30) to automatically open out to the expanded position shown in
The assembly 20a can be positioned in several different configurations for use, thereby enhancing its utility to the user. For example, the user can use the assembly 20a in the same manner described above for the assembly 20, as shown in
To store the assembly 20a, the user first deflates the floatation devices 50 so that the entire assembly 20a can have a generally flat profile. The sheet material 30a of the assembly 20a can then be folded a compact configuration for storage.
While the description above refers to particular embodiments of the present invention, it will be understood that many modifications may be made without departing from the spirit thereof. The accompanying claims are intended to cover such modifications as would fall within the true scope and spirit of the present invention.
