Description: BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to inflatable play structures, and more particularly, to children's play structures, such as inflatable houses and tunnels, which are easily attachable to and removable from each other by using hook and loop fasteners. Discussion of the Related Art Children enjoy playing in inflatable toy structures. Conventional inflatable toy structures are individually free standing without being able to interconnect between them. Many types of toys have been devised to help develop children's body spatial relationships. As an example, rigid tubes positioned together, end to end with a wood base, to prevent rolling, are presently in use. Other such tunnels, using helical spring steel hoops covered with a cloth or plastic material are commonly in use and are known in the industry. In child growth, the use of devices that help development of body control in motion, such as creeping and crawling, are becoming more prevalent. Presently, rigid structural tubes, or pipes, are in use both indoors and out. Flexible collapsing tunnels are especially popular for indoor use, however, these devices, as well as the outdoor equipment with a hard bottom surface, have a tendency to scuff the children's legs and clothing and are uncomfortable when in use. Children are typically fond of tunnel like structures, such as large boxes, in which they may play. This preference is embodied in many playgrounds and parks and indoor toys where enclosed slides and tire tunnels are commonly constructed for the children's enjoyment. Recognizing the play value of tunnels, several toy tunnel structures have been developed in the prior art and marketed to children. As is typical with such prior art toy tunnels, the tunnel structure only has openings at its two ends. Accordingly, using a single tunnel structure, children can only enter into one opening and exit at the other opening. As a result, the amusement value of the tunnel quickly wanes as the children become familiar with the tunnel structure. The continuous structure of the toy tunnel and other structure also makes it very difficult to assemble the play structures in a confined area or indoors. A play structure with much more entertainment value is one that allows a child to enter and exit at multiple points. As a result, more than one child can play with the play structure at once, meeting at various points without concern of one child blocking another's passage. Play structures with multiple entrances and exits have been limited mostly to playhouse structures and tents. However, these devices are not easily connectable among each other. Therefore, there is a need in the art for an interconnecting inflatable play structure that can be easily attachable to and removable from other play structures to provide entrances at multiple points. Accordingly, several structures can be joined together in hundreds of differing configurations. A Known inflatable play structure is described in United States Patent 4,629,182. In this document a play structure is disclosed which contains a first structure with a cavity sufficiently large to hold a child and a side wall with an opening. It also discloses a second, similar structure, which can be releasably attached to the first one. Disadvantage of the know structure is the difficulty of connecting the structures in an effective way. SUMMARY OF THE INVENTION Accordingly, the present invention is directed to an interconnecting inflatable play structure that substantially obviates one or more of the problems due to limitations and disadvantages of the related art. An object of the invention provides a multitude of combined shapes and matrixes when houses and tunnels are joined together. A number of tunnels and houses may be attached in tandum with one end of the assembly connected to a multiple opening intersection. Also, others may be attached projecting at various angles therefrom. This flexible arrangement allows the children to use their imagination and creativity in organizing the desired shape or form. Another object of the invention provides collapsible and deflatable play structures, thereby allowing the house and tunnel structures to be easily stored when not in use. Still another object allows construction with cost effective material, such as polyvinyl chloride sheeting, or any other substance having characteristics suitable for inflating, including thermoplastic impregnated cloth, and the like. Additional features and advantages of the invention will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by practice of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS With reference to the drawings, and in particular to Figs. 1-8 thereof, an interconnecting inflatable play structure embodying the principles and concepts of the present invention will be described. Fig. 1 illustrates a perspective view of a preferred embodiment of an interconnecting inflatable play structure 100. Fig. 2 illustrates a detached view of Fig. 1 showing a tunnel 106 placed between and connecting two inflatable playhouses 102, 104 according to the preferred embodiment of the present invention. The present invention is directed to an interconnecting inflatable play structure 100 typically used by children for use in in- or out-doors. The interconnecting inflatable play structure 100 includes a plurality of play structures which are easily interconnected to allow children to move between or among various play structures, such as houses and tunnels. According to the preferred embodiment, the interconnecting inflatable play structure 100 includes a first inflatable house 102 connected to a second inflatable house 104 through an inflatable tunnel 106. The use of the first and second inflatable houses 102, 104 and the inflatable tunnel 106 are for illustration purposes only and should not limit the scope of the present invention. The present invention may be used with any number of inflatable houses with or without tunnels. In the preferred embodiment, a continuous side wall 110 includes a plurality of polygon shaped, preferably rectangular, walls. In particular, the side wall 110 comprises an inflatable first side wall 201 having an opening 116, front wall 202 having an opening 118, second side wall 203 and rear wall 204 both of which do not have any openings. The openings 116 and 118 are sufficiently large to allow children to enter or exit the inflatable house 102 or 104. The first side wall 201 has an appearance of a corrugated surface to simulate the shape of a plurality of vertical tubes fused or connected side by side. The first side wall 201 preferably has one air pocket or chamber which defines a rectangular opening 116 once inflated with pressurized air. The same is also true for the front wall 202. The second side wall 203 and the rear wall 204 each includes a plurality of vertical tubes which are in fluid communication with respect to each other. The side edges of the walls 201, 202, 203 and 204 are fused together in tandum to form the continuous side wall 110 using such process as radio frequency sealing or other process known to one of ordinary skill in the art. In the preferred embodiment, each one of the walls 201, 202, 203 and 204 is individually equipped with an air valve to insert and discharge pressurized air. The material for the first house 102 is comprised of a flexible inflatable material, such as polyvinylchloride sheeting (typically referred to as PVC), thermoplastic impregnated cloth or other materials known to one of ordinary skill in the art. The first inflatable house 102 also includes two arched inflatable support tubes 114 preferably placed at the four corners of the side wall 110. The support tubes 114 extend over the height of the side wall 110 to form the facades of the house. Each support tube 114 is equipped with an inflation air valve 115 for the insertion and discharge of pressurized air. The two arched inflatable support tubes 114 are preferably made with PVC or other suitable materials. Placed between two support tubes 114 is a ceiling tube 113 to define the top of the first inflatable house 102. The ceiling tube 113 has independent air chamber. Two ends of the ceiling tube 113 are fused between the two support tubes 114 using a suitable process, such as radio frequency sealing or other process known to one of ordinary skill in the art. Chamber is equipped with an inflation air valve 115 for the insertion and discharge of pressurized air. The ceiling tube 113 is also preferably made with PVC or other suitable materials. As shown in Figs. 1 and 2, the first inflatable house 102 has a roof sheet 112 supported by and attached to the ceiling tube 113 and the two arched inflatable support tubes 114. In particular, the middle of the roof sheet 112 is supported by and attached to the ceiling tube 113. The side edges of the roof sheet 112 are fused to the upper portion of the support tubes 114 to form a roof of the first inflatable house 102. The roof sheet 112 is preferably made with a PVC sheet or fabric for easy folding and flexibility. As shown in Fig. 2, the first inflatable house 102 has a plurality of flaps 160, 166 extending from the lower end portion of the side walls having child access openings 116, 118. In particular, the first inflatable house 102 has a side flap 160 and a front flap 166 extending from the lower end portion of the side wall 201 and the front wall 202, respectively. Each flap includes a pair of hook and loop fasteners securely affixed thereto for easy connection with another toy play structure equipped with hook and loop fasteners. The side flap 160 and the front flap 166 are each made of at least one layer of PVC sheets which are used for constructing the side and bottom walls. Because the flaps are not inflated, the hook and loop fasteners can be stitched directly onto each respective flaps. In addition, other suitable attachment method may also be use, such as using adhesives, etc. Preferably, the side and front flaps 160, 166 extend along the length of their respective sides between four vertical posts formed by two arched supports 114. The details of the flap 160, 166 and the hook and look fasteners are described with respect to Figs. 6 and 7. Referring to Figs. 1 and 2 and similar to the first inflatable house 102, the second inflatable house 104 includes a continuous side wall 122 fused at four corners to the arched support tubes 126. The components and the structure of the second inflatable house 104 are identical to that of the first inflatable house 102 and therefore the description with regard to such components will not be repeated here. As shown in Fig. 2, the second inflatable house 104 also has a plurality of flaps 170 and 176 extending from the lower end portion of the side walls having child access openings 128, 130. In particular, the second inflatable house 104 has a side flap 170 and a front flap 176 extending from the bottom edge of the side wall and the front wall, respectively. Each flap includes a pair of hook and loop fasteners 172, 174 securely affixed thereto for each connection with another toy play structure or one or more tunnels. According to the preferred embodiment, one or more inflatable tunnels may be used with inflatable houses to provide access to one or more inflatable houses interconnected with the tunnels. The inflatable tunnel 106 is placed, for example, between the first and second inflatable houses 102 and 104 to connect the front opening 118 of the first inflatable house 102 and the front opening 130 of the second inflatable house 104. The inflatable tunnel 106 includes three arched tubes 140, 142 and 144 which are serially placed with two opposite tubes 140, 144 placed at an equal distance from the middle tube 142. Connected between the arched tubes 140, 142 and 144 are inflatable tubes 146 that are fully or partially covering the roof portion of the tunnel 106. Also placed between the arched tubes 140, 142 and 144 are inflatable side walls 148 having windows 149 to allow viewing of the tunnel's interior. The side walls 148 and the inflatable tubes 146 are preferably in fluid communication with each other so that one air valve can be used to input pressurized air into the inflatable tunnel 106. The inflatable tubes 146 and the side walls 148 of the inflatable tunnel 106 are made of PVC or other suitable material known to one of ordinary skill in the art. The inflatable tubes 146 are fused together with the side walls 148 by such method as radio frequency sealing or by using adhesives or other methods known to one of ordinary skill in the art. The tunnel 106 also includes a bottom wall 156 which comprises a rectangular tube with a plurality of air pockets. The side walls 148 and the arched tubes 140, 142 and 144 are erected from and fused to the top surface and along the length of the bottom wall 156. In particular, the bottom ends of the side walls 148 and the arched tubes 140, 142 and 144 are fused together with the bottom wall 156 to complete the dome portion of the tunnel 106. The bottom wall 156 is also preferably made with the same material as the side walls 148. The tunnel 106 includes a first opening 150 and a second opening 152 for allowing children to crawl therethrough. In particular, the openings 150 and 152 are defined by the arched tubes 140 and 144 and the bottom wall 156. The diameter of the first and second openings 150 and 152 is sized to substantially cover the front openings 118 and 130 of the first and second inflatable houses 102 and 104, respectively. As shown in Fig. 2, the inflatable tunnel 106 includes first and second flaps 180 and 186 extending from the opposite ends of the bottom wall 156 for connecting with the first and second inflatable houses 102 and 104. Each one of the first and second flaps 180 and 186 has a plurality of hook and loop fasteners which are aligned with the hook and loop fasteners placed on the flaps of the inflatable houses 102 and 104. Fig. 3 illustrates a left elevational view of the interconnecting inflatable play structure of Fig. 2. Fig. 3 shows the side openings 116 and 128 of the first and second inflatable houses 102 and 104. The front flaps 166 and 176 and the front openings 118 and 130 of the first and second houses 102 and 104 are hidden from view as they are blocked by the supports 114 and 120. The first and second flaps 180 and 186 of the tunnel 106 are extended from the opposite ends of the bottom wall 156. Fig. 4 illustrates a right elevational view of the interconnecting inflatable play structure of Fig. 2. The side walls of the play house 102 and 104 shown in Fig. 4 do not have any openings and are solidly blocked. As shown in this particular arrangement, the two inflatable houses 102 and 104 and the inflatable tunnel 106 are linearly positioned to allow children to travel from the first house 102 to the second house 104. The first and second flaps 180 and 186 of the inflatable tunnel 106 are aligned with the front or side flaps of the play houses 102 and 104 for easy connection and disconnection by children. Fig. 5 illustrates a bottom planar view of the interconnecting inflatable play structure 100 of Fig. 2. As shown, the first and second flaps 180 and 186 extending from the bottom wall 156 of the inflatable tunnel 106 are overlapped with the front flaps 166, 176 of the first and second houses 102 and 104. The pair of hook and loop fasteners 164 of the front flap 166 are aligned with the hook and loop fasteners 182 of the first flap 180. Similarly, the pair of hook and loop fasteners 174 of the front flap 176 are aligned with the hook and loop fasteners 184 of the second flap 186. Fig. 6 illustrates a detail view of a flap 166 extending from the inflatable tunnel 106 having a pair of hook and look fasteners 164 affixed thereon. Fig. 7 illustrates a detail view showing the connection between the inflatable tunnel 106 and a play house 102. In the preferred embodiment of the present invention, the hook and loop fasteners 164 are placed on an under surface of the front flap 166 of the first and second houses 102 and 104. However, the first and second flaps 180 and 182 extending from the inflatable tunnel 106 have the hook and loop fasteners 182, 184 on the upper surface to interlockingly overlap the corresponding opposite flaps, as shown in Fig. 7. As a result, the flaps may be tilted at any angle to allow, for example, the tunnel 106 to be at an angle with respect to the first inflatable house 102 to allow the children to use the tunnel 106 as a slide. Moreover, because the hook and loop fasteners, by their design, collect and hold loose hairs, dirt, threads, etc., the use of the uninflated overlapping flaps prevent foreign objects from being tangled with the hook and loop fasteners. In addition, unlike the hook and loop fasteners which are directly attached to an inflated structure, the hook and loop fasteners of the preferred embodiment of the present invention will not tear off from the flaps because the flaps are not inflated. Fig. 8 illustrates a detached view of the interconnecting inflatable play structure 300 according to a second embodiment of the present invention. The second embodiment has substantially identical first and second play houses 302 and 304 and the inflatable tunnel 306. However, in lieu of having the front and side flaps in the play houses 302, 304 and the first and second flaps in the tunnel 306, the hook and loop fasteners are directly affixed to the side of the bottom tubes of each structure. The hook and loop fasteners are positioned so that each respective piece of play structure needs to be pushed against each other for attachment. In particular, the hook and loop fasteners 308 of the first house 302 are aligned with and connected to the hook and loop fasteners 310 of the inflatable tunnel 306. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
