Abstract
A tent having a fabric body defining an internal volume and a door for entering and exiting the internal volume and for providing ventilation to the internal volume. A continuous zipper is located on the periphery of the door and on the door opening. A pair of zipper slides is configured for traversing the continuous zipper enabling the door to completely open, completely close and open partially in any one of a number of orientations.
Description




TECHNICAL FIELD OF INVENTION




The present invention is directed to a structure which is provided with an opening and a closable door. More specifically, the present invention is most appropriately applied to a tent having a fabric body. By employing the appropriate continuous zipper arrangement together with a pair of zipper slides, the door can be completely closed, completely open or partially opened in a number of various configurations.




BACKGROUND OF THE INVENTION




Fabric tents are generally provided with an open doorway and a side wall whereupon a fabric door is applied. Although the fabric door can be appended to the tent fabric by any one of a number of well-known means, it is quite commonplace to attach the door to the fabric tent body by one or more zipper arrangements. In addition, oftentimes, tents are provided with a two-ply door having air venting fabric as a first ply and a waterproof fabric as a second ply. Regardless of these details of construction, all such doors are characteristically limited as to orientations which the door can assume as it is opened.




Perhaps the most relevant teaching regarding the present invention can be found in U.S. Pat. No. 5,765,584. The '584 patent teaches a fabric tent having a two-ply door and a “continuous” zipper which defines a C-shaped arcuate path. A pair of zipper slides are mounted on the zipper path such that a pair of consecutively positioned zipper slides unzips the waterproof fabric to allow ventilation through the air-venting fabric when the pair slides towards one another while the waterproof fabric is zipped closed when the pair slides away from each other.




Although the '584 patent offers a certain degree of flexibility, the zipper employed by this reference is not continuous. As such, the tent door is limited in the orientations it can assume. For example, reference is made to FIG. 1 which depicts an embodiment shown in the '584 patent. When zipper slides 47a and 47b are mounted on zipper 41, the door 40 can be opened and closed. Specifically, when the zipper slides 47a and 47b are moved to the opposite tips of the C-shaped arcuate path, the tent door is in a closed position. A motion of the zipper slide 47a in a clockwise direction or a motion of zipper slide 47b in a counter-clockwise direction unzips tent door 40. Conversely, a motion of the zipper slide 47a in a counter-clockwise direction or a motion of the zipper slide 47b in a clockwise direction closes the tent door 40. However, the tent door cannot be fully stashed away for there is a gap between the ends of the zipper where sliders 47a and 47b reside in FIG. 1. Further, door 40, in the illustration made herein, can only open to the left. In the event that it would be more convenient or practical to open the door to the right, the configuration of FIG. 1 would prove inadequate. Finally, as noted previously, if door 40 was to be stashed away, it could not fully be withdrawn from the tent opening in which it resides for the gap between sliders 47a and 47b cannot traverse the open area not occupied by zipper 41. It is deemed to be desirable to be able to join the sliders together to virtually completely withdraw tent door 40 from the tent opening particularly to enhance ventilation and in the event that large objects which have a difficulty in clearing the tent opening must be brought into or withdrawn from the tent's interior volume.




It is thus an object of the present invention to provide a tent which experiences none of the drawbacks as discussed above which are characteristic of prior designs. These and further objects will be more readily appreciated when considering the following disclosure and appended claims.




SUMMARY OF THE INVENTION




The present invention is directed to a tent of the type having a fabric body defining an internal volume and a door for entering and exiting the internal volume and for providing ventilation. The improvement comprises providing a continuous zipper on the door and on the fabric body. A pair of zipper slides are employed for traversing the continuous zipper enabling the door to open in virtually any desired configuration.

DETAILED DESCRIPTION OF THE INVENTION




As noted previously,

FIG. 2

represents a schematic illustration of the present invention. Specifically, fabric tent


27


is shown as having a traditional door


20


enabling a user to enter and exit the tent's internal volume. The present invention, however, differs from prior embodiments in that continuous zipper


21


is provided as a means of attaching door


20


to fabric tent body


27


. Along continuous zipper


21


which is shown as defining the peripheral edge of door


20


are located a pair of zipper slides


22




a


and


22




b.


In the orientation shown in

FIG. 2

, the zipper slides abut in a first position thus completely closing door


20


as the teeth of that portion of the zipper maintained by the door completely mesh with the corresponding teeth of the zipper sewn into tent fabric


27


. By employing this configuration, the present invention provides a degree of flexibility as noted with respect to

FIGS. 3A

,


3


B and


4


which are unachievable by similar devices employed in the past.




Turning to

FIG. 3A

, the present invention is shown as door


20


is partially opened such that the door is swung to the left exposing the backside


20




a


of door


20


and exposing internal space


25


created as zipper slides


22




a


and


22




b


reside opposite one another. In turning to

FIG. 3B

, zipper slides


22




a


and


22




b


have been caused to travel along continuous zipper


21


in the opposite direction exposing internal space


25


of tent


27


as door


20


partially swings to the right exposing its back side,


20




a.


In comparing

FIGS. 3A and 3B

, it is noted that tent


27


can be made as having a right or left hand door which, as noted previously, is not achievable by the prior art.




Turning to

FIG. 4

, internal space


25


is shown to be completely exposed to the tent's opening by moving zipper sliders


22




a


and


22




b


to a second abutting orientation as shown. In such a configuration, tent door


20


can be rolled into a very tight and compact package and stowed any place along continuous zipper


21


.

FIGS. 5A and 5B

show two alternative means for capturing and retaining door


20


when the configuration as depicted in

FIG. 4

is desired. For example, pouch


30


can be positioned on tent fabric body


27


proximate the door opening. The tent fabric can be rolled into a tight package and stuffed into pouch


30


which conveniently keeps tent door


20


from in any way obstructing entrance or exit from internal space


25


. As an alternative embodiment, once door


20


is compactly rolled, strap


31


sewn to tent fabric


27


can wrap around door


20


employing Velcro® or similar expedient to maintain the strap in place.




As noted previously, various means can be employed for retaining door


20


when the zipper slides abut along zipper


21


to completely open the tent to its interior space


25


. These expedients can be appended to tent fabric


27


at any point along zipper


21


. In order words, when stowing door


20


as shown in FIG.


4


and

FIGS. 5A and 5B

, door


20


need not be stowed at the apex of the door opening. Again, such flexibility is unachievable by practicing the prior art.
