## Title
Portable baby tent

## Abstract

A collapsible tent provides insect protection for infants such as less than a year old while being small and portable enough for use in many public spaces. Excellent ventilation and visibility are provided by mosquito and no-see-um blocking fabric formed into a dome-like shape. Flexible support rods cross one another at the apex of the tent and reside within arch-shaped fabric channels. A detachable or alternatively attached ground barrier completes the enclosure. For storage, the flexible support rods are brought adjacent to one another to form a flat arch-shape with the pair of proximate ends then coiled toward the other pair to form a small circular shape that is readily retained within this compact shape by a carrying pouch. When the tent is erected, the carrying pouch is attachable to the tent to serve as a sunshade. A hanging support inside the tent may be used to suspend infant toys.

## Background
REFERENCE TO RELATED APPLICATIONS
The present application claims the benefit of U.S. provisional patent application Ser. No. 60/564,923 of the same title filed 22 Apr. 2004.


FIELD OF THE INVENTION
The present invention relates, in general, to portable cabanas and tents, and more particularly to such devices that provide protection for infants from insects and summer sun.
BACKGROUND OF THE INVENTION
There is an increasing awareness that flying insects pose a serious health risk, rather than being merely an annoyance. With the spread of mosquito-borne diseases, such as West Nile virus in temperate regions, parents are seeking ways to protect young children and infants. While insect repellants are often used, the more effective formulations with DEET used by adults are not recommended for children. That is especially true for infants who are prone to suck on surfaces that may be sprayed with repellants.
Many insect protective barriers are known to screen in beds and cribs from mosquitoes. In addition, ever lighter and more easily erected camping tents are available that are well ventilated yet block insects. However, there are instances where these generally known insect barriers are too inconvenient to be used. For instance, at an outside youth sporting event, such as soccer or baseball, parents and siblings are arrayed along the sidelines of a field. It would be inconvenient to carry and setup a camping tent just to protect children, even if the physical confines of the area would permit it.
Consequently, a significant need exists for an insect barrier to protect small children that is extremely portable and not too obtrusive for use in public spaces.
BRIEF SUMMARY OF THE INVENTION
The invention overcomes the above-noted and other deficiencies of the prior art by providing a tent formed largely of a mesh material that provides excellent ventilation while blocking flying insects such as mosquitoes. The tent is carried in a flat, coiled configuration that is easily carried. The tent is erected quickly by removing the tent from a pouch, whereupon its flexible support rods spring toward an arch shape, as constrained within the mesh fabric. Drawing the crossed support rods into a more perpendicular cross shape erects an open bottom tent that may be easily placed over a child seat.
In one aspect of the invention, a tent has a dome-like shape that is readily supported by a pair of crossed straight support rods that are flexed by and restrained within sewn channels that are transversely affixed to the mesh material. The ends of one support rod may be drawn toward respective ends of the other support rod to flatten the tent. Drawing the proximate pair of ends toward the other proximate pair of ends forms a roughly circular flat shape that is then inserted into a circular pouch for storing and transporting. A flat ground cloth is shaped to underlie the tent to further block insects that may be on the ground. Thereby, a tent may be quickly erected and placed over an infant seat while at a park to provide protection from insects.
These and other objects and advantages of the present invention shall be made apparent from the accompanying drawings and the description thereof.



BRIEF DESCRIPTION OF THE FIGURES
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and, together with the general description of the invention given above and the detailed description of the embodiments given below, serve to explain the principles of the present invention.
FIG. 1 is a top perspective view of a collapsible tent assembly for providing protection to infants from insects, including a ground barrier, an open bottom tent, and a carry pouch attachable to the tent for sun protection.
FIG. 2 is a perspective view of the collapsible tent assembly of FIG. 1 after the tent has been collapsed.
FIG. 3 is a perspective view of the collapsed tent of FIG. 2 after having been led into a small circular shape.
FIG. 4 is a perspective view of the coiled tent being placed in the carry pouch.



DETAILED DESCRIPTION OF THE INVENTION
Turning to the Drawings, wherein like numerals denote like components throughout the several views, in FIG. 1, a collapsible tent assembly 10 is shown prepared to receive an infant seat (not shown). In particular, a ground barrier 12 has been unfolded and placed upon the ground to act as a barrier to moisture, dirt and insects. A collapsible tent 14 has been erected into its dome-like shape with its rectangular open bottom 16 sitting upon the ground barrier 12. A carrying pouch 18 from which the collapsible tent 14 and ground barrier 12 have been taken may be conveniently attached to the collapsible tent 14 to prevent its being misplaced as well as providing an adjustable sun shade for a protected infant.
The collapsible tent 14 includes four mesh fabric side panels 20–26 that allow ventilation and visibility while blocking insects, thereby, not distressing the protected infant. A pair of sewn fabric channels 28, 30 transverse to one another, pass from opposite bottom corners across the top of the collapsible tent 14, each of the pair 28, 30 having an arch shape. A bottom band 32 of like material forms a square shape connecting these four bottom corners. Ties 34 on the collapsible tent and ties 36 on the ground barrier 12 allow an enclosed space to be formed on uneven ground where otherwise a space may exist therebetween. The ties 34, 36 may comprise instead paired snaps, Velcro attachments, or be omitted. Inside of the collapsible tent 14 attached to its apex is a hanging attachment 38 that may be used to support infant toys (not shown) to amuse the protected infant.
A pair of straight, flexible support rods 40, 42 reside within and are constrained by respective ones of the pair of sewn fabric channels 28, 30. Being unconnected but merely passing by the other at the top of the collapsible tent 14, a parent may fold the collapsible tent 14 into a flat, arch-like shape as depicted in FIG. 2 by drawing the transversely positioned support rods 40, 42 into an adjacent alignment. By further coiling the support rods 40, 42 to form a small circular shape, as depicted in FIG. 3, the collapsible tent 14 may be readily inserted into the carrying pouch 18 for storage or transporting.
As an illustrative version of the collapsible tent assembly 14, the support rods 40, 42 may be fabricated from flexible oil tempered spring steel (e.g., 0.0915 OTNB) or fiberglass that reside within channels 28, 30 made of a grosgrain ribbon or 170 T polyester. The mesh fabric panels 20–26 may be formed from No-See-Um mosquito netting (NN01). The ground barrier 12 may be formed of nylon or 210 T polyester ripstop. The carrying pouch 18 may be formed from polyester or nylon fabric.
As an alternative to having an open bottom tent 14 with a detachable ground barrier 12, the ground barrier 12 may be attached to the tent 14, further simplifying assembly and providing greater assurance of insect protection. A closable opening, such as a flap or slit that may be sealed with attaching means (e.g., Velcro, snaps, zipper, S-hook/fabric loop, etc.) may be provided on at least one panel 20–26 to provide access to the interior of the tent 14. Such a slit may be a vertical slit or an inverted-J shaped opening.
While the present invention has been illustrated by description of several embodiments and while the illustrative embodiments have been described in considerable detail, it is not the intention of the applicant to restrict or in any way limit the scope of the appended claims to such detail. Additional advantages and modifications may readily appear to those skilled in the art. For example, since the tent 14 may be readily lifted and replaced, the tent 14 may also serve to protect picnic food from insects.
As another example, a permanent sunshade portion may be incorporated into the tent 14 so that the carrying pouch 18 need not be used. This may be particularly important in versions consistent with aspects of the invention where the tent 14 is open bottomed and may be readily rotated to maintain shade on the protected infant. It may be further appropriate in embodiments wherein integral fasteners on the tent 14 are included to maintain the tent in a coiled shape for storage and transport without having to use a carrying pouch 18.
