Multi-use flotation device
A multi-use flotation device (e.g., 100) includes two end sections (e.g., 101, 103) integrally connected to a central section (e.g., 102). The central section is configured and arranged to accommodate a torso of the user without significantly impeding a full range of movement of the appendages of the user when the user lays on at least the central section. The end sections are characterized by respective geometric shapes that are generally wider than the central section. One of the end sections accommodates at least a head of the user when the user lays on at least the central section. The other end section accommodates at least a derriere of the user when the user lays on at least the central section. The two end sections and the central section together form a concave, unitary device.
This application claims priority upon U.S. Patent Application Ser. No. 60/721,905, entitled “MINI FLOATATION DEVICE”, under 35 U.S.C. § 119(e), which application is incorporated by reference herein in its entirety.
BACKGROUND OF THE INVENTIONThe present invention relates generally to flotation devices and, in particular, to a multi-use flotation device that permits a user to lay comfortably thereon while floating in the water without significantly impeding movement of the user's appendages (e.g., arms and/or legs).
Flotation devices are well known. Such devices come in variety of shapes and sizes and are available in inflatable and non-inflatable forms. Non-inflatable flotation devices (i.e., devices that float without requiring air to be injected into any portion of them by the user) are typically made from open cell or closed cell foam materials. A classic example of an open cell flotation device is the water noodle. Closed cell foam flotation devices are available from various manufacturers, such as Texas Recreation Corporation of Wichita Falls, Tex.
Most flotation devices have a single intended use. For instance, a raft is intended to be laid upon while the user floats in a pool or other body of water; whereas, a floatable chair is intended to be sat in under the same circumstances. However, these single use devices often impede or restrict motion of the user's arms and/or legs during use, thereby preventing a full range of motion of the user's appendages. For example, the overall structure and configuration of the raft prevents a user from flutter kicking in the water while lying on the raft. Additionally, a user can often not readily lower his or her arms or legs while resting in a floatable chair.
Other flotation devices have a variety of intended uses, including permitting full motion of the user's arms and/or legs. For example, the WATER JOGGER floating exerciser manufactured by Texas Recreation Corporation is one such device. The WATER JOGGER device is a generally narrow, rectangular device that includes a notch or dip in a center area to accommodate a crotch of the user. Advertising for the WATER JOGGER device suggests that a user may use the device in various ways, such as by (i) straddling the device to keep the user's hair dry and hands free for water games and/or aqua jogging, (ii) placing the device transversely under the head of the user for use as a headrest, (iii) placing the device transversely under the chest of the user for use as a chest rest during forward flutter kicking, and (iv) placing the device transversely along the upper back and under the arms of the user for use as a back rest during backward flutter kicking.
While the WATER JOGGER device has several purported uses, it is not configured to accommodate a torso of a user and thereby allow a user to lay upon it. In other words, the WATER JOGGER device is not configured to permit it to be used in a raft-like manner. Therefore, a user that wants to float in a generally prostrate manner on his or her back or stomach must use an additional flotation device.
Therefore, a need exists for a flotation device that has multiple uses, including allowing a user to float on his or her back or stomach without significantly impeding the user's ability to move his or her arms and/or legs.
BRIEF DESCRIPTION OF THE DRAWINGS
Before describing in detail exemplary embodiments that are in accordance with the present invention, it should be observed that the embodiments reside primarily in combinations of apparatus components related to implementing a multi-use flotation device. Accordingly, the apparatus components have been represented where appropriate by conventional symbols in the drawings, showing only those specific details that are pertinent to understanding the embodiments of the present invention so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein.
In this document, relational terms, such as “first” and “second,” “top” and “bottom,” and the like, may be used solely to distinguish one entity or element from another entity or element without necessarily requiring or implying any actual such relationship or order between such entities or elements. The terms “comprises,” “comprising,” or any other variation thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements, but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. A claim element proceeded by the article “a” or “an” does not, without more constraints, preclude the existence of additional identical elements in the process, method, article, or apparatus that includes the element.
Generally, the present invention encompasses a multi-use flotation device for use by a user in a body of water. The flotation device includes two end sections integrally connected to a central section. The central section is configured and arranged to accommodate a torso of the user without significantly impeding a full range of movement of the appendages of the user when the user lays on at least the central section. The end sections are characterized by respective geometric shapes that are generally wider than the central section and optionally taper toward the central section. One of the end sections accommodates at least a head of the user when the user lays on at least the central section. The other end section accommodates at least a derriere of the user when the user lays on at least the central section. The two end sections and the central section together form a concave, unitary device. In some embodiments, the flotation device has a generally hour-glass shape and/or is constructed from closed cell foam. In other embodiments, the tapering between the end sections and the central section, when included, is non-linear (e.g., curved) and/or the overall length of the flotation device is selected to permit a full range of motion of the user's legs when the user is in a prostrate position.
By constructing a flotation device in this manner, the present invention provides a device that is sized and shaped to not only facilitate sitting or leaning upon the device, as does prior art multi-use devices, but also to facilitate laying upon the device while still maintaining a substantially free range of motion of the user's arms and/or legs. In other words, in contrast to prior art multi-use devices that facilitate movement of a user's arms and legs but do not facilitate use of the device in a raft-like manner, the present invention provides a multi-use flotation device than can be used in a raft-like manner while maintaining the benefits of other multi-use devices.
The present invention can be more readily understood with reference to
The first end section 101 is preferably configured in a generally circular shape to accommodate a head and possibly part of the shoulders of a user when the user lays on the flotation device 100 as contemplated herein. The second end section 103 is also preferably configured in a generally circular shape to accommodate a derriere and possibly part of the upper legs of a user when the user lays on the flotation device 100 as contemplated herein. In alternative embodiments, the first and second end sections 101, 103 may be other predetermined geometric shapes as discussed below. In a preferred embodiment, the flotation device 100 is symmetric along its length and/or width; therefore, the first end section 101 may function as the second end section 103, or vice versa, depending on the orientation of the flotation device 100 with respect to the user.
The central section 102 of the flotation device 100 is configured and arranged to accommodate a torso of the user without significantly impeding a full range of movement of the user's arms and/or legs when the user lays on the flotation device 100. The central section 102 interconnects at a first end 105 with the first end section 101 and interconnects at a second end 106 with the second end section 103. The ends 105, 106 of the central section 102 are identified by phantom lines and are used for reference only. In one embodiment intended for use by older children and adults, the lineal distance between the ends 105, 106 of the central section 102 is in the range of about twenty (20) inches to about twenty-eight (28) inches. In an embodiment intended for use by younger children, such lineal distance would, of course, be shorter (e.g., in the range of about sixteen (16) inches to about twenty-four (24) inches).
In an adult embodiment of the flotation device 100 depicted in
In a preferred embodiment, the three sections 101-103 of the flotation device 100 have substantially the same thickness 201 in the range of about one (1) inch to about two (2) inches. Additionally, the overall length of the flotation device 100 is selected such that a full range of motion may be achieved by a user of the device 100. For example, in one embodiment, the overall length of the flotation device 100 is approximately equal to the average length from the top of the head to the top of the hamstring of the group of intended users of the device 100. For instance, in an embodiment intended for use by older children and adults, the overall length of the flotation device 100 may be in the range of about forty-four (44) inches to about fifty (50) inches. The overall length for a device 100 intended for use by younger children would be shorter (e.g., in the range of about thirty-two (32) inches to about forty-four (44) inches).
The flotation device 100 may optionally include one or more apertures 108, 109 (two shown) in the end sections 101, 103 to accommodate at least part of a hand of the user. The apertures 108, 109 preferably act as handles to enable the user to carry the unitary flotation device 100 to and from a desired destination (e.g., the pool or the beach). The apertures 108, 109 may have other uses also, such as providing a means by which a user can balance himself or herself while sitting on the flotation device 100 or providing a means by which the flotation device 100 can be readily retrieved in the event that the user were to fall off the device 100 for any reason. In one embodiment, the apertures 108, 109 have a generally oval shape with a length in the range of about three (3) inches to about five (5) inches and a width in the range of about one (1) inch to about two (2) inches. One of ordinary skill in the art will readily recognize that the apertures 108, 109 may be of other shapes and sizes as desired by the user.
