Abstract
The tent frame includes an upper hub with a plurality of ribs intended to extend outwardly and a lower hub having an equal number of stretchers. The ends of the stretchers are pivotally connected to the ribs. As the lower hub moves upwardly, the stretchers force the ribs outwardly to erect the tent. Flexible cords extend down from the upper hub through the lower hub and out apertures in the bottom of the lower hub. Pulling the cords apart from within the tent causes the lower hub to move upwardly toward the upper hub to erect the tent. Alternatively, the cords can be passed around pulleys in the lower hub and upwardly through apertures in the top of the upper hub. Pulling the cords apart from above the tent causes the lower hub to move upwardly toward the upper hub to erect the tent.
Description
- The present invention is directed toward a foldable tent and more particularly, toward an improved frame for a foldable tent that allows a person to erect or open the tent from inside or outside of the same.
- Quick opening tents of the type to which the subject matter of this application is directed are, per se, well known in the art. Examples can be found in U.S. Pat. No. 5,479,954 that issued to Lin on Jan. 2, 1996 and U.S. Published Application No. 2007/0062569 to Joo-Tai published Mar. 22, 2007.
- All such prior art tents are structurally very similar and operate in substantially the same manner. They all include a tent fabric supported on a frame. The fabric can be secured to the inside or the outside of the frame. The frame includes a plurality of elongated ribs that are pivoted to an upper hub and which are intended to extend radially outwardly therefrom. The frames also include an equal number of elongated stretcher members that are pivoted to a lower hub and to the ribs. As the lower hub moves axially upwardly toward the upper hub, the stretcher members force the ribs outwardly to erect the tent. The system works essentially like an umbrella being opened.
- To assist the user in opening or erecting such prior art tents, the frame conventionally includes a flexible cord that has one end secured to the lower hub. The cord then extends upwardly through an axial opening in the upper hub where it is accessible from above the tent on the outside thereof. The tent is erected by pulling upwardly on the cord to pull the lower hub upwardly toward the upper hub. In some cases, the distal end of the cord may include a handle or the like to assist the user in gripping the cord to pull it up. As the cord is pulled upwardly, it is also frequently necessary to push the upper hub downwardly to ensure that the lower and upper hubs are being drawn together.
- While such prior art tents may work well, they do present certain problems, particularly with larger tents. Depending on the height or width of the tent, it may sometimes be difficult to reach the cord at the top of the tent frame. And even if one could reach the cord, it might be difficult to apply enough force to pull the same upwardly to erect the tent. Obviously, some taller people may be able to erect such prior art tents, while others may not be able to do so.
- Thus, there is a need for a foldable tent frame that can be easily opened or erected by someone who may not be able to reach over the top of the tent to open the same from above.
- The present invention is designed to overcome the deficiencies of the prior art discussed above. It is an object of the present invention to provide a foldable tent frame that can be opened without having to reach over the top of the tent.
- It is another object of the present invention to provide a foldable tent frame that can be opened from inside the tent.
- It is an even further object of the present invention to provide a foldable tent frame that can be opened from inside the tent or from above the tent from the outside thereof.
- In accordance with illustrative embodiments demonstrating features and advantages of the present invention, there is provided a tent that has a tent fabric and a frame adapted to support the fabric on either the inside or the outside thereof. The frame includes an upper hub with a plurality of elongated ribs pivotally connected thereto and intended to extend radially outwardly and a lower hub having a plurality of elongated stretcher members having first ends pivotally connected thereto. The number of elongated stretcher members is equal to the number of ribs and the free ends of the stretcher members are pivotally connected to the ribs. As the lower hub moves axially upwardly toward the upper hub, the stretcher members force the ribs outwardly to erect the tent. Flexible cords are held in the interior of the upper hub and extend downwardly through the lower hub and out apertures in the bottom of the lower hub. Manually pulling the cords apart from within the tent causes the lower hub to move upwardly toward the upper hub to erect the tent. Alternatively, the cords can be passed around pulleys in the lower hub and be directed upwardly through the upper hub and through apertures in the upper surface of the upper hub. Manually pulling the cords apart from above the tent causes the lower hub to move upwardly toward the upper hub to erect the tent.
- Other objects, features and advantages of the invention will be readily apparent from the following detailed description of a preferred embodiment thereof taken in conjunction with the drawings.
- For the purpose of illustrating the invention, there is shown in the accompanying drawings one form that is presently preferred; it being understood that the invention is not intended to be limited to the precise arrangements and instrumentalities shown.

FIG. 1 is a front perspective view of the major portion of the tent frame of the invention shown in its fully collapsed condition; -
FIG. 2 is a view similar toFIG. 1 showing the tent frame in its initial stage of being erected; -
FIG. 3 is another view similar toFIGS. 1 and 2 illustrating a further stage of the opening of the tent frame; -
FIG. 4 illustrates the tent frame in its fully opened or erect position; -
FIG. 5 is a bottom perspective view of the hub system used with the present invention with the cords arranged for opening the tent from the inside thereof; -
FIG. 6 is a side elevational view of the hub system ofFIG. 5 ; -
FIG. 7 is a cross-sectional view similar toFIG. 6 but showing the interior of the hubs; -
FIG. 8 is a top perspective view of the hub system used with the present invention with the cords arranged for opening the tent from the outside thereof; -
FIG. 9 is a side elevational view of the hub system ofFIG. 8 , and -
FIG. 10 is a cross-sectional view similar toFIG. 9 but showing the interior of the hubs. - Referring now to the drawings in detail wherein like reference numerals have been used throughout the various figures to designate like elements, there is shown in
FIGS. 1-10 a foldable tent constructed in accordance with the principles of the present invention and designated generally as 10. Although the tent 10 includes atent fabric 12, this is, per se, conventional and is, therefore, being shown only diagrammatically in figures. Thefabric 12 is not being shown in most of the figures so that the frame 14 and the operation thereof can be seen in more detail. Again, it should be pointed out that the present invention can be used with the type of tent that has the fabric secured to either the interior or exterior of the frame. That is, the frame can be inside of or outside of the tent fabric. - As with many prior art tent frames, the frame 14 includes an
upper hub 16 and alower hub 18 arranged therebelow but in axial alignment therewith. A plurality of elongated ribs, such as shown at 20 and 22, have their upper ends pivotally connected to theupper hub 16. While six such ribs are shown in the figures, it should be clear that this is by way of example only. Fewer or more ribs may be employed depending on the nature and size of the tent 10. - A plurality of stretcher members such as shown at 24 and 26 have their lower or inner first ends pivotally connected to the
lower hub 18. The number ofelongated stretcher members ribs stretcher members ribs - As illustrated in
FIGS. 1-4 , as thelower hub 18 moves axially upwardly toward theupper hub 16, thestretcher members ribs first hub 16 to form the erected tent. Extending upwardly from thelower hub 18 at the center thereof and axially aligned therewith is aspindle 28. This is, perhaps, best seen inFIG. 3 . As shown best inFIGS. 7 and 10 , the lower portion of theupper hub 16 includes arecess 30 which is complementary in shape to the shape of the upper part of thespindle 28. As the upper andlower hubs spindle 28 enters therecess 30 to ensure proper alignment and provide a stop means for properly positioning the hubs in spaced relationship as shown inFIGS. 7 and 10 . Temporary locking means can be provided to lock the upper andlower hubs - With the exception of the
spindle 28 andrecess 30 just described, the tent and tent frame 14 and the operation thereof described above are conventional. Examples can be found in the patent to Lin and the published application to Joo-Tai referred to above. For convenience, the entire disclosure of the Lin patent and the Joo-Tai publication are incorporated herein by reference. As can be seen in Lin and Joo-Tai, the upper and lower hubs are drawn together by a cord that is attached to the lower hub and passes upwardly through the upper hub so as to be exposed at the top and exterior of the tent. By pulling on the cord from the top of the tent, the lower hub is drawn upwardly to erect the tent. The improved hub arrangement of the present invention allows the tent to be erected from either above and outside of the tent or from inside of the tent. - The details of the hub system of the present invention that allow the tent to be erected from either above the tent or inside the tent are shown in
FIGS. 5-10 . With reference first toFIGS. 5 , 6 and 7, it can be seen that aflexible cord 32 extends around asupport 34 that is fixedly secured within the interior of theupper hub 16. The twofree ends cord 32 extend downwardly through the interior of thespindle 28 and throughapertures lower wall 44 of thelower hub 18. Preferably, thelower wall 44 is in the form of a cover or cap that can be snapped onto or otherwise secured to thelower hub 18 and which can be removed when desired. - The use of a
single cord 32 that extends around the fixedmember 34 as shown inFIG. 7 is, of course, by way of example only. It is possible to use two separate distinct cords that each have their upper ends fixed in some manner within the interior of theupper hub 16. It is also within the scope of the present invention to use only a single cord having its upper end secured within thehub 16 and the lower end extending downwardly through one of theapertures - If a single cord such as either
cord hubs lower hub 18. This movement will draw thehubs lower hub 18. Rather, grasping each of the two cords with a different hand and moving the hands apart will force thelower hub 18 upwardly as the sides of theapertures -
FIGS. 8 , 9 and 10 illustrate how the identical system can be utilized to erect the tent from above. To accomplish this, thecords lower hub 18 and then extend upwardly throughopenings spindle 28 and throughsimilar apertures recess 30. Thecords apertures upper hub 16. As with thelower cap 44, theupper cap 62 is adapted to be temporarily secured to the top of theupper hub 16 so that it can be removed when desired. - With the
cords top wall 62 of theupper hub 16 as shown inFIGS. 8 , 9 and 10, the tent can be erected by holding the cords and pulling them up while pushing down on the top 62 of theupper hub 16 or by drawing thecords apertures hubs - The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof and accordingly, reference should be made to the appended claims rather than to the foregoing specification as indicating the scope of the invention.
