The present invention relates to a double entrance for use in an inflatable enclosure for amusement purposes and/or promoting physical activity.
In the prior art, there exists many Inflatable Structures. One such example is found in U.S. Pat. No. 3,159,165, which discloses an inflatable air-supported structure, having a door which may be made out of wood, fiberglass, or other rigid or semi-rigid material. Other examples which can be found are U.S. Pat. Nos. 3,250,024; 3,335,529; 3,769,763; 3,903,659; 4,103,369; 4,164,829; 4,974,829; French patent publication No. 2,101,367; and Soviet patent publication No. 667,649. Of the above, those references purporting to teach the use of an inflatable structure for amusement purposes are: U.S. Pat. Nos. 4,103,369; 4,164,829; and French patent publication No. 2,101,367.
Applicant's prior patents namely U.S. Pat. No. 5,471,797 and U.S. Pat. No. 5,603,185 include a single entrance. Applicant has found that the single entrance does not maintain the pressure in the inflatable enclosure adequately when a plurality of people enter the enclosure. Also, Applicant has found that some children are slower in entering the enclosure, and keep the doors open for an extended period of time which causes partial deflation of the inflatable enclosure.
Nowhere within the prior art, is there shown, as far as applicant is aware, an inflatable structure which has means to prevent substantial deflation of the inflatable enclosure when a person enters and/or exits it. By preventing substantial deflation of the enclosure when a person enters and/or exits the enclosure, the enclosure remains substantially inflated thus maintaining a comfort level for those entering the inflatable enclosure and those watching, for example, parents watching children when entering the enclosure.
Accordingly, it is an object of the present invention to provide an inflatable enclosure, for use as not only an amusement device for children, but also as a physical activity promoter as well.
Yet still another object of the invention is to provide an inflatable enclosure which has ventilation means to regulate the pressure and quality of air therein.
It is still another object of the invention to provide a method of amusing and promoting physical activity (i.e., cardiovascular, muscular, etc.), and teaching children hand-eye, foot-eye coordination, within an inflatable enclosure.
It is yet another object of the invention to provide an inflatable enclosure inflated by a blower or the like. A further object of the invention is to provide an inflatable enclosure which has an air actuated (air inflatable) entrance and exit area that minimizes pressure loss and air loss in the enclosure, when entering and/or exiting the enclosure, and preferably allows a person entrance into and exit from the inflatable enclosure without aid from another person.
According to one aspect of the invention, there is provided an inflatable enclosure for amusement purposes and/or promoting physical activity comprising:

While the foregoing provides a detailed description of preferred embodiments of the invention, it is to be understood that this description is illustrative only of the principles of the invention and not limitative. Furthermore, as many changes can be made to the invention without departing from the scope of the invention is intended that all material contained herein be interpreted as illustrative of the invention and not in a limiting sense.
A preferred embodiment of the present invention is a lightweight inflatable walk-through attraction containing inflated obstacles. A small slide, in one instance approximately 6 feet high and preferably angled approximately 30° to the horizontal, is located at the exit of the attraction, outside the body.
Patrons enter at the mouth of the attraction and walk through to the exit at the tail.
Preferably there are numerous windows and vent holes to permit the operator and other adults to supervise the activities of the children inside. Communication with the occupants can be through the vent holes or simply through the fabric itself.
Preferably, in addition to the main entrance and exit, there are emergency exits consisting of zippered openings placed at the centre on either side so that no patron is more than 3 meters from any exit.
The attraction is supported by air pressure, however preferably a set of plastic hoops may be supplied and placed at 3 meter intervals to afford some support in the event of deflation.
Preferably, the attraction is anchored at the points shown additionally, and preferably when hoops are used their bases are fixed down to provide further restraint.
The anchors, may preferably be ⅝″ bar candy-cane shape, and are to be inserted at least 16″ into firm ground. Alternatively, sandbags each may be used, preferably sandbags weighing 50 lbs.
To set up the unit according to a preferred embodiment of the present invention, it should be set up on a suitable surface. It should not be secured down until it is inflated. One should connect the blowers to the air ducts and secure with the Velcro tape. The blower should be directly connected to the power supply. Inflate the unit, making sure the blower is on high setting and that all deflation vents are closed. The unit can now be secured, for example, staked down. The stakes should be driven into firm ground to a minimum depth of 16 inches. A grassed area will be sufficiently firm. Maximum wind speed for safe operation is 30 km/hr (20 mph).
To operate the preferred embodiment of the present invention at least one operator shall be on duty at all times the unit is being used. The maximum capacity of the unit is 6 persons. It is preferable, to group children by size and age, do not allow small children in at the same time as larger and more boisterous children. The wearing of shoes is not allowed. It is preferable to remove any hard or sharp objects, eg. Pens, buckles, jewelry, etc. It is also preferable to remove glasses. The unit should not be used when wet. It is preferable for the person using the unit to not have any gum or face paint. Children should not deliberately collide with each other. Waiting children should stand at least 3 feet (1 meter) from the front of the unit. In case of power failure the operator should assist the children out of the unit immediately using both main and emergency exits and do not allow them to re-enter until power is restored and the unit fully inflated. The operator should walk through the deflated attraction to ensure no child remains inside.
The unit can be easily cleaned with a cloth or light brush. Use a vinyl cleaner and rinse thoroughly to remove detergent before storing. Do not pack the unit away when wet. If this is unavoidable, lay the unit out to dry at the earliest opportunity.
The unit should be inspected regularly for damage. If there is evidence of tearing at the anchor points, the unit should not be used until repairs have been made.
The unit depicted as a preferred embodiment of the present invention and ones very similar to it have been inspected and tested several times. The tests have been limited to a stability check of the slide and deflation.
Deflation: the body of the attraction deflates quite quickly in one instance, around 1 minute. This time reduces if all emergency exits are opened. Once deflated, the structure is somewhat erect if the hoops are used and a fairly clear view along the interior can be had when fully deflated. One can readily walk through the attraction in this condition and no child can be concealed from an adult doing this. The walk-through can be done in less than 10 seconds.
While the foregoing provides a detailed description of a preferred embodiment of the invention, it is to be understood that this description is illustrative only of the principles of the invention and not limitative. Furthermore, as many changes can be made to the invention without departing from the scope of the invention, it is intended that all material contained herein by interpreted as illustrative of the invention and not in a limiting sense.
