BACKGROUND OF THE INVENTION

The present invention relates to human-bearing inflatables and more particularly pertains to multi-function inflatables serving in one or more roles as furniture or as exercise/recreation/therapy equipment.
Human-bearing inflatables are used as furniture as well as exercise, recreational, and therapy devices. However, few devices of the prior art are significantly multi-function, and none combine the benefits of low cost, robustness, and multi-functionality. Simple, rounded shapes with minimal seams and seals offer the highest robustness and lowest manufacturing costs, but generally lack multifunctionality. For example, large rubber and PVC balls (“Swiss balls”, “Pilates balls”, etc.) are widely used for exercise and therapy, but their tendency to roll makes them unsafe for inexperienced users and limits their usefulness as furniture. Ball chairs and ball supports, which hold a ball in a shallow plastic or metal ring, require non-inflatable and costly additional components and do not support intensive recreational-exercise activities. Inner tubes, which, like balls, are also a low-cost and robust shape, are limited by their shape to a few recreational uses, even with added handles, tow points, etc. (E.g. U.S. Pat. No. 5,476,404.) Furthermore, mass-produced inner tubes are often unattractively asymmetrical when inflated outside of tires.

BRIEF SUMMARY OF THE INVENTION

In accordance with the present invention, an inflatable device comprises an inflated spheroid and an inflated base sized so as to fit together to form a stable form suitable for seating, recreation and/or exercise. These can consist of mass-produced molded components (i.e. an exercise ball and a mass-produced inner tube), providing a high degree of robustness at low cost.
The device may include one or more additional options. It may include a system of straps or a form-fitting covering for correcting some asymmetry in the base form. It may include equipment for controlling and-or generating sound, lights and-or video responsive to the actions of person(s)on or around the device. It may also incorporate a weighted bottom to prevent excessive movement during use.
Objects and Advantages
Accordingly, besides the objects and advantages of the human-bearing inflatable described in my above patent, several objects and advantages of the present invention are:
(a) to form a human-bearing inflatable device capable of serving as furniture and/or equipment for exercise, recreation, and/or therapy;
(b) to reduce the cost of manufacturing by employing mass-produced components;
(c) to form a highly portable human-bearing inflatable device;
(d) to form a highly robust human-bearing inflatable device;
(e) to provide, optionally, a simple means for correcting any asymmetry in the base component;
(f) to provide, optionally, a sound, lights, and/or video show responsive to users' movements; and
(g) to incorporate, optionally, a weighted bottom to prevent excessive movement during use.
Still further objects and advantages will become apparent from a consideration of the ensuing description and drawings.

DETAILED DESCRIPTION OF THE INVENTION

FIGS. 1A-1D: Preferred Embodiment

FIGS. 1A-1D depict a preferred embodiment of the invention. In this embodiment, the device is composed of an inflatable spheroid 1 and an inflatable base 2 with a center hole, sized so that said spheroid sits securely in said hole. In a preferred embodiment, the spheroid is made of rubber or PVC, similar to any large exercise or “Pilates” ball. Alternatively, it may be made of any material forming a rounded shape that can support the weight of a person. In additional preferred embodiments, said spheroid is an ellipsoid, egg-shape, rounded-end cylinder, or another generally rounded shape fitting securely into the opening of base 2.
In a preferred embodiment, said base 2 comprises an inner tube, such as those used in car, truck, and tractor tires. In additional embodiments, said base comprises an inflatable form with one or more cavities or holes in which one or more spheroid(s) of said type may sit securely. Said base can be made from rubber, PVC, neoprene, or other material appropriate for a human-bearing inflatable. In an additional embodiment, the spheroid and/or base incorporate handles.
In accordance with the present invention, alternative embodiments may use proportions between the base form and the spheroid form different from those shown in the figures to optimize the device for a particular mode of use. The spheroid 1 and base 2 may be sized to seat individuals of a particular size on the base 2 with the spheroid 1 as a back rest. In this application, an ellipsoidal or cylindrical spheroid may be employed to provide a better back rest. Alternatively, the spheroid 1 and base 2 may be sized to seat individuals of a particular size on the spheroid 1 with the base 2 as a foot rest. For other uses, the optimal proportions will be apparent to anyone skilled in the art.
A pad may be placed around the device (or incorporated into the device) in any of the described embodiments to prevent injury in case a user falls off of the device.

FIGS. 2A-2D: Additional Embodiment

FIGS. 2A-2D depict an embodiment similar to that of FIGS. 1A and 1B, with the addition of a system of straps 3 and 4 surrounding the base 2. In a preferred embodiment, this system consists of a set of straps encircling the base in several places as shown in the figures. The base-surrounding straps 3 can be kept in their proper positions by fixing them to an additional strap 4 encircling the base's inner diameter. The straps 3 and 4 may consist of nylon, polypropylene, fabric, rubber, or any other material strong and flexible enough to surround the base while deflated, inflated, and under use. The pictures show four base-surrounding straps 3. In accordance with the invention, however, the system could include any number of such straps.
In a preferred embodiment, each base-surrounding strap 3 may include a buckle, snap, velcro, or other closure device to allow the system to be easily installed and removed. Said closure devices may allow the lengths of the straps to be changed individually. In an alternative embodiment, each of these straps 3 is sewn together around the base. In either case the base-surrounding straps 3 can correct for asymmetry in the base by constraining its expansion as it inflates. This system may serve additional or alternative purposes, such as to provide attachment points for a decorative or protective covering, handles, head rest(s), foot rest(s), sensors, switches, lights, speakers, etc. An example of such use is shown in FIGS. 3A-3F and FIGS. 4A-4F.
As an alternative embodiment, the system around the base consists of a form-fitting covering, rather than, or in addition to straps. This covering may serve to correct asymmetry by constraining the expansion of the base as it is inflated; it may also provide attachment points for an additional decorative/protective covering as mentioned above. This form-fitting covering may consist of fabric, mesh, neoprene, rubber, or some combination of these or other materials capable of serving one or more of the above-mentioned purposes.
Additional embodiments include having a head rest on top of the spheroid, an injury-preventing pad extending around the edge of the base, handles attached to the straps, or some combination of these additional elements.
It will be evident to those skilled in the art that the above-described straps, covering(s), handles, etc. may be employed on any of the following embodiments as well.

FIGS. 3A-3F: Additional Embodiment

FIGS. 3A-3F illustrate an embodiment of the present invention incorporating components to generate some combination of sound, lights, and/or video responsive to user(s) actions on and/or around the device. Components 6, 7, 8, 9, 10, and 1 2 are attached to additional straps 5 which run across the bottom of the device and are anchored to the base itself or to the straps/covering. FIG. 3F shows the functional relationship of these components.
As shown in FIG. 3E, one or more sensor elements 10 can be positioned between a strap 5 and spheroid 1 to detect and/or measure users' activity on spheroid 1. The sensor 10 may be a pressure sensor such as piezoresistors, or a quantum-tunneling composite (such as those available from Peratech Ltd.). It may incorporate voltage sources and/or voltage dividers to generate a signal measurable by analog to digital converter 9. Such pressure sensors may also be placed under various parts of the device (such as under the base 2, or off-center under spheroid 1) to sense the weight and movement of users on various parts of the device. In further additional embodiments, other types of sensors may be placed on or around the device to sense user activity in those areas. These may be accelerometers, proximity sensors (electromagnetic-, IR-, or ultrasound-based), photosensors, piezoelectric sensors, microphones, temperature gauges, or other type(s) which can detect or measure the activity of users on or around the device.
The functional connections of the interactive components are illustrated in FIG. 3F. The sensors' output attaches to the input of the analog to digital converters 9. The digital output of said converters is connected to the digital signal processor (DSP) 12, the output of which connects to some combination of light source(s) 6, sound generators 7, and/or video generators 8. The digital signal processor 1 2 consists of computer(s) and/or circuitry capable of translating digital sensor data into analog voltages and/or digital data to control the actuators 6-8. In a preferred embodiment, said DSP 12 consists of a digital computer with appropriate ports and programming. The output of DSP 12 is some combination of analog audio (e.g. mono, stereo, Dolby 5.1, etc.), analog video (e.g. composite, S-video, RGB, HD, VGA, etc.), other voltage output (e.g. control signals), digital audio (e.g. SPDIF, Firewire audio, digital Dolby surround, etc.), digital video (e.g. DV, DVI, etc.), and/or digital control signals (e.g. MIDI, RS-232, USB, Firewire, etc.).
The light sources 6 are some combination of light bulbs, rope lights, LEDs, electroluminescent material, or other light source (with any necessary power supply or control circuitry) whose output can be controlled by control signals (analog or digital) output by DSP 12. FIGS. 3C and 3D show such a light source underneath the device; however, they may also be on or around the device.
In a preferred embodiment, the sound generator(s) 7 consist of one or more amplifiers connected to one or more speakers. In additional embodiments, said sound generators include audio synthesis capabilities controlled by the DSP 12 (e.g. by MIDI signals). Portions of sound generator 7 may be incorporated in the device (e.g. FIG. 3C) while other portions (such as speakers) may be external to the device.
In a preferred embodiment, the video generator 8 comprises one or more computers programmed to create video output in response to control signals from DSP 12. Alternatively it may comprise a dedicated video synthesizer/generator operating in response to control signals from the DSP 12. In either case the video generator 8 may be connected (using an analog or digital signal) to one or more display devices such as a CRT, video projector, plasma screen display, LCD, etc. The DSP 12 may also feed video directly to such display device(s) without use of a video generator 8.

FIGS. 4A-4F: Additional Preferred Embodiment

FIGS. 4A-4F illustrate an embodiment of the present invention allowing for switches 13 to control the interactive components 6, 7, and/or 8, without requiring a DSP 12. Additional straps 5 across the bottom of the device provide anchor points for components 6, 7, 8, and 13.
FIG. 4F shows the functional relationship of these components. In this embodiment, user(s) actions actuate switches 13 which directly control the output of some combination of light sources 6, sound generators 7, and/or video generators 8. In a preferred embodiment, the switches 13 consist of mechanical switches or quantum tunneling composite switches. In this embodiment, the switches 13 vary in resistance according to user(s) actions, controlling the flow of current to components 6, 7, and/or 8. In an alternative embodiment, the switches 13 incorporate circuits, such as voltage dividers, to generate voltages which control components 6, 7, and/or 8. The switches 13 may include sensors such as piezoresistors, quantum-tunneling composites, accelerometers, proximity sensors (electromagnetic-, IR-, or ultrasound-based), photosensors, piezoelectric sensors, microphones, temperature gauges, or any other sensor which can control current flow or generate a voltage in response to the presence and/or activity of users.

FIGS. 5A and 5B: Additional Preferred Embodiment

In this embodiment, a weight 11 is incorporated into the device by attaching it to the system of straps 3 and 4. In a preferred embodiment, the weight 11 is a hollow container of plastic, fabric, rubber, or other appropriate material, filled with a dense material such as water, sand, or lead shot. Alternately it may consist of any shape fitting below the device weighing enough to substantially limit displacement of the device when used. The weight may also be incorporated into the spheroid 1 and/or the base 2, either as an additional fillable compartment in one or both inflatables or by placing a dense material in one or both inflatables. Weighting of the device as described may be incorporated into any of the previously described embodiments.
Advantages
From the description above, a number of advantages of the described inflatable device become apparent:
(a) The device can be used as furniture and/or as equipment for exercise, recreation, and/or therapy.
(b) The device can be formed from inexpensive mass-produced components.
(c) The device can be highly compact and portable when deflated.
(d) The device can be robust enough for vigorous use.
(e) Asymmetry in inflated components can be easily corrected.
(f) The device can provide a sound, lights, and/or video show responsive to users' activity.
(g) The device can be weighted to prevent excessive displacement during use.

Operation of Preferred Embodiment

In its most basic preferred embodiment (shown in FIGS. 1A and 1B), the device has multiple potential uses as furniture and as equipment for exercise, recreation, and/or therapy. One or more users may sit, and/or bounce on the base 2, using the spheroid 1 as a back rest. A user may sit on the spheroid 1, placing feet on the base 2 or on the ground. An additional, smaller form of the device can be used as a foot rest. Users can also lie on the spheroid 1 or the base 2, stand on the base 2, lean on the base 2, kneel on the base 2, or position themselves on the device in a variety of ways. In an embodiment including handles, users may grasp the handles while lying supine or prone on the spheroid 1 for an upper body stretch or workout.
For exercise, recreation, or therapy, users can bounce or stretch in any of the above positions, perform stretches over the spheroid 1, perform floor exercises with parts of their bodies on the device, or enjoy any number of other positions and activities. Most ball-based exercises can be performed on the device, with the added safety of the stability provided by the base 2. New exercises are also made possible, such as balancing on the stabilized spheroid 1. The spheroid 1 can also be removed from the base 2 to perform conventional ball exercises.
The addition of straps or a form-fitting covering on the base 2 (e.g. FIGS. 2A and 2B) allows for the correction of some asymmetry in the base 2, as well as providing attachment points for additional decorative/protective coverings or interactive components. The correction may be achieved by selective tightening of the straps 3 surrounding the base 2, or the straps/covering may be manufactured in a form that will enforce symmetry as the base 2 is inflated. A covering of the base 2 may protect from sharp objects, abrasion, sunlight, and/or excessive temperature.
In the interactive embodiments (e.g. FIGS. 3A-3F and 4A-4F), users may interact with the device in any of the above-described ways, with the device providing lights, sound, and/or video responsive to user(s) activity. In the DSP-based embodiment (i.e. FIGS. 3A-3F), sensors 10 detect and/or measure the presence, movement, and/or weight of users. The sensor signals are digitized by the A/D converters 9; this digital data is then used by the DSP 12 (which may include digital and/or analog outputs) to drive some combination of light sources 6, sound generators 7, and/or video generators 8. A multimedia show controlled by the user(s) is thus created. In a preferred embodiment, the sensors 10 are pressure sensors generating a waveform representing a user's bouncing on the device. In this preferred embodiment the DSP 12 converts the pressure data into music, flashing lights, and/or a video show (by driving corresponding components 7, 6, and 8), with a rhythm matching that of the user's bouncing, encouraging further use.
In the switch-based embodiment (i.e. FIGS. 4A-4F), the presence, movement, and/or weight of users affects the output of switches 13. The switch output directly controls some combination of light sources 6, sound generators 7, and/or video generators 8. A multimedia show controlled by the user(s) is thus created. In a preferred embodiment, the rhythm of the generated show matches that of a user's activity.
In the additional embodiment incorporating a weight 11, the mass of the device is increased and its center of gravity lowered, reducing the device's movement during intensive use. In a preferred embodiment, the weight 11 is hollow, so that it may be shipped or transported empty.
Conclusion, Ramifications, and Scope
Accordingly, the reader will see that the inflatable device of this invention can be used as furniture and as exercise/recreational/therapeutic equipment. It can be constructed from inexpensive components (i.e. exercise balls and inner tubes). Asymmetry in the base can be corrected easily, ensuring the device's attractive appearance. The device can respond interactively to user(s) actions by generating lights, sound, and/or video responsive to their actions, enriching the experience of using the device and making it an audio-visual instrument. It can also be weighted to prevent excessive movement during intensive use.
Thus the scope of the invention should be determined by the appended claims and their legal equivalents, rather than by the examples given.
