Interlocking tent clips for quick setup

Abstract

A tent clip design for coupling with similar adjacent clips comprises a C-shaped upper portion (11) that can be snapped onto a tent pole (12), a webbing slot (19) at the bottom for attaching a loop of webbing (20) extending up from the tent (21) below, a laterally extending tongue (14) with a toothed lower surface (15) near its distal end, and a corresponding tongue slot (16) immediately below the tongue with a toothed upper surface (17) on its lower edge to join in locked engagement with the toothed lower surface (35) of tongue (34) of a similar adjacent tent clip (30) when two or more similar clips are aligned and pressed together. The portion of the clip below the tongue slot is made of flexible material and comprises flexible portion (18) of the clip. A user of the clip can interlock the clip with similar adjacent clips into clusters which can be far more rapidly mounted than can the same number of separated clips, and with considerably less likelihood of being attached in the wrong sequence or orientation, or attached to the wrong pole. Once the clusters are mounted on the poles, a user of the clips can pull down on loops of webbing (20) residing in webbing slots (19) to temporarily widen tongue slots (16) and axially release any toothed tongues held within the tongue slots. The user can thus disengage interlocked clips individually or may disengage them in groups by pulling simultaneously on their webbing or on the attached tent fabric. Thus the tent clip considerably simplifies and expedites the otherwise tedious process of connecting tent clips to overlying support poles. This will greatly reduce the exposure of mountaineers, particularly less experienced mountaineers, to the extreme weather conditions commonly prevailing when tents are erected at high altitudes.

Description

BACKGROUND

1. Field of the Invention

This invention relates to tent clips, specifically to easier-to-use tent clips for attaching tent fabric to an overlying pole.

2. Prior Art

Tents are supplied with their component parts disassembled and packaged. The parts must be unpacked and assembled to erect the tent. Reducing the time required to erect a tent properly may be more than a convenience. In high-altitude, extreme conditions, tent setup can test the patience of even highly experienced alpinists. For the less experienced, simplifying and hastening this process may become a matter of survival.

Many tents used by backpackers and mountaineers employ a series of clips to attach the tent fabric or body to overlying support poles. Such tents usually have from one to six flexible poles, which arch over the body of the tent, with each pole end being attached to the perimeter of the tent fabric. A series of tent clips, each attached to the tent fabric by a strap or piece of webbing, are then attached to the pole in order to support the tent body and to hold the pole in correct alignment. A typical tent may have twenty or more of these clips. Attaching the clips to the support poles is frequently the most time-consuming step in setting up a tent. To attach each clip individually requires considerable time. However, to ensure proper attachment, each clip must be correctly aligned, positioned, and then somehow held in this arrangement prior to attachment to the overlying poles. This is not a simple or a quick process to perform, particularly in extreme weather conditions. If any of the above steps are omitted, or hastily performed, it is likely that some clips will be attached in the wrong orientation and sequence, and frequently to the wrong poles. Thus, further setup time is often required to detach and then reattach errant clips. Ways of expediting this tedious tent setup process are understandably in great demand by tent users and manufacturers.

U.S. Pat. No. 1,643,183 to Smith (1927) and U.S. Pat. No. 1,690,694 to Nissen (1928) show clips which connect on one side to a cord or webbing, while U.S. Pat. No. 4,315,351 to Bartolini (1982) shows a clip that attaches directly to fabric by ultrasonically welding a protruding polymeric tab into the fabric. While these clips do have means that would allow them to be attached to webbing or fabric, no means of simplifying or expediting the process of attaching tent clips to tent poles is shown or suggested.

U.S. Pat. No. 4,193,413 to Watts et al. (1980) shows a means for releasably attaching fabric to an overlying pole, as does U.S. Pat. No. 5,002,083 to Kim (1991) and U.S. Pat. No. 5,421,355 to Cantwell (1995). However none of these patents suggest or show any way to expedite tent clip placement.

In conclusion, no tent clip formerly developed or known addresses or meets the need for systematically organizing and expediting the process of connecting tent clips to tent support poles.

OBJECTS AND ADVANTAGES

Accordingly, several objects and advantages of the invention are to provide an improved tent clip, to provide means of expediting tent setup, and to provide a swifter, more user-friendly, yet economical, means of attaching tent fabric to tent poles. Further objects are to provide means of releasably interlocking adjacent tent clips, and to provide means of releasing interlocked tent clips that may be quickly and easily activated. Still further objects and advantages will become apparent from a study of the following description and the accompanying drawings.

SUMMARY

In accordance with the invention, an improved tent clip for attaching a tent pole to tent fabric comprises a C-shaped upper portion which can be snapped onto the pole, a webbing slot at the bottom for attaching a loop of webbing extending up from the tent below, a laterally extending tongue with a toothed lower surface near its distal end, and a corresponding tongue slot immediately below the tongue with a toothed upper surface on its lower edge to join in locked engagement with the toothed lower surface of the tongue of a similar adjacent tent clip when two or more similar clips are aligned and pressed together. The material comprising the lower side of the tongue slot and the other material surrounding the webbing slot is flexible so that pulling down on a loop of webbing residing in the webbing slot will temporarily widen the tongue slot and will axially release any toothed tongue held within the tongue slot. Interlocked clips may be thus disengaged individually or in groups by pulling simultaneously on their webbing or on the attached tent fabric.

Description--FIG. 1--Front View

FIG. 1 is a front view of a molded plastic quick setup tent clip 10 constructed in accordance with the invention. The clip comprises a body which has a C-shaped upper connector or portion 11 that forms a tent pole gap 13. The clip is preferably made of a flexible or deformable plastic material, such as nylon, and is about 70 cm high, 5 cm thick, and 8 cm wide, with other parts scaled proportionately. The C-shaped upper portion is generally circular and gap 13 subtends about 40 degrees of the circle. A tongue 14 extends down and out about 5 cm from the clip and is visible above a webbing slot 19.

Description--FIG. 2--Rear View

FIG. 2 is a rear view of the clip 10, showing a tongue-receiving slot 16 above webbing slot 19. Slot 16 (FIG. 3) is behind and is bordered on its top side by the underside of tongue 14. Tongue 14 and slot 16 comprise a side interconnector for connecting adjacent clips, as will be described.

Description--FIG. 3--Cross Section

FIG. 3 is a rear oblique cross section through two identical clips 10 and 30 that have been aligned and pressed into interlocking contact. Tongue 14 of clip 10, on the left, has been pressed into tongue slot 36 of clip 30, on the right. That is, when the two clips are pressed together, tongue 14 of clip 10 is pressed into tongue slot 36 of clip 30 such that the lower surface 15 of tongue 14 of clip 10, which is toothed, engages and locks onto upper surface 37 of the lower edge of tongue slot 36 of clip 30, which is also toothed.

The two clips are held thusly together until flexible portion 38 of clip 30 is deformed downward. This widens tongue slot 36 of clip 30 so that toothed lower tongue surface 15 of clip 10 disengages from toothed upper surface 37 of the lower edge of tongue slot 36 of clip 30. This allows clips 10 and 30 to separate axially. The downward pull on flexible portion 38 of clip 30 can easily be supplied when desired by pulling downward on a piece of webbing (not shown in this figure) which is looped through webbing slot 39.

Description--FIG. 4--Front Oblique View

FIG. 4 is a front oblique view of tent clip 10 hanging from a tent pole 12 after gap 13 of clip 10 is snapped over pole 12. A snap fit is created here because gap 13 is just slightly smaller than the outside diameter of pole 12. As shown, the diameter of the opening or lumen of the clip is substantially larger than the diameter of pole 12 so that the clips can slide freely on the pole. Tongue 14 is visible above the flexible portion 18 of the clip. Webbing 20, sewn to fabric tent 21, is looped through webbing slot 19. If a downward pull is exerted on webbing 20, and thus on flexible portion 18, deformation of flexible portion 18 will occur, as was described above in the description of FIG. 3.

Description--FIG. 5--Front View

FIG. 5 is a front oblique view of a fabric tent 21 connected to two overlying tent poles 12 by quick setup tent clips 10. A tent base pole support (or restraint) 22, made of webbing or a strap (preferably nylon) is sewn to the main body of the tent. Each tent base pole support 22 has a grommet 23 through which the end of tent pole 12 is inserted during the process of setting up the tent. Locking pole tips may be used, if desired, at the ends of the poles to more securely connect the pole ends to the tent base pole supports.

OPERATION

The manufacturer will initially supply the tent with the clips attached to the tent body but not to the poles. The manufacturer may or may not supply the tent with the clips clustered initially to aid in the first setup of the tent.

If the clips are not clustered initially, the user will need to attach them individually to the poles for the first usage or tent setup. The individual clips are attached to the pole by snapping gaps 13 of C-shaped upper portions 11 over the pole in sequence, or by inserting the pole in sequence through the aligned lumens or openings of upper portions 11 of the clips. Once the clips are attached to the poles in the correct order and orientation (at their first usage) they will no longer require individual attachment for subsequent setups.

If the clips are clustered initially, each cluster is joined to its pole by snapping all clips in the cluster over the pole, or by inserting the pole through the aligned lumens of upper portions 11 of the cluster.

After the clips are attached to the poles and the tent is set up in the normal manner, it will appear as in FIG. 5. That is, the main body of the tent fabric will be suspended from the poles by the clips and the ends of the poles will be held or restrained by supports 22.

To strike, or take the tent down, the clips are pressed together in clusters while still attached to the pole, in preparation for the next setup of the tent. The clips may be pressed and locked or snapped together into clusters while on the pole by aligning all the clips to be clustered and then pressing them against a locked pole tip on one end of the pole. This is done by pushing the clip furthest from the locked pole tip towards the locked pole tip, with the clips facing in the same direction. The user then compresses the cluster axially such that tongue 14 of each clip in the cluster enters tongue slot 16 of the adjoining clip (FIGS. 1, 2, 3, and 4). The user presses with enough force to snap each toothed lower tongue surface 15 of each clip into locking engagement with the corresponding toothed lower edge 17 of tongue slot 16 of each adjacent clip. This will interlock the clips of the cluster. Since the clips are attached to the tent, clustering the clips will also crumple or compress the tent fabric (not shown). Normally two to six clips will be pressed together for each cluster and there will be one cluster for each pole.

Once the clips are pressed together into clusters, the pole tips are disconnected from tent base pole supports 22 and the clip cluster is slid off each pole. After the tent is thus taken down it will be further compressed and put into a stuff sack for carrying. The poles are also collapsed for transport.

Succeeding tent setups are considerably easier and faster than the first setup. With the clip clusters for each pole already formed, each cluster may be snapped over its corresponding pole, via aligned gaps 13. Each pole end is then inserted into grommet 23 (FIG. 5) of tent base pole support 22. Alternatively the pole may be inserted into aligned lumens of upper portions 11.

The user can then axially release the interlocked clips easily, rapidly, and automatically by simply pulling webbing 20 attached to each clip, either one at a time or in groups. This pull will temporarily deform flexible portions 18 of the clips and enlarge tongue slots 16 to allow an axial release of toothed tongues 14 held within slots 16. Thus, the joined clips will separate from each other axially and will assume positions along the pole according to the spacing of webbing straps 20 (FIG. 5).

To strike the tent again, the clips are first reclustered as before, the poles are detached from their restraints 22, the clusters are slid off the poles, and the tent and poles are repacked.

CONCLUSION, RAMIFICATIONS, AND SCOPE

The reader will see that I have provided an improved tent clip that can be produced economically and that will greatly simplify and expedite tent setup. Tent clips can be quickly snapped together in clusters to allow the clips to be mounted onto their support poles in groups rather than individually, greatly expediting the mounting process and greatly reducing the likelihood of some clips not being mounted, or being mounted in the wrong sequence or the wrong orientation, or mounted to the wrong poles. The ease of disconnecting the interlocked clips--with a simple tug--also saves time and effort, especially critical in extreme weather conditions.

While the above description contains many specificities, these should not be construed as limitations on the scope of the invention, but as exemplifications of the presently preferred embodiments. Many other ramifications and variations are possible within the scope of the invention. For example, side-release plastic buckle technology or other push-button release mechanisms can be applied to the means of release of the interlocked tongue from the tongue slot. More teeth, or differently-shaped teeth, can be added to the interlocking means. The clip can be adapted to connect to poles that are not overhead, or not to poles, but rather to ropes or webbing. The upper end of the clip can be changed from a C-shaped hook with a side opening to a hook in the shape of an upside-down U, with the opening at the lower end. Or the clip can be a closed ring without any opening. Flexible "keepers" can be added just inside the tent clip pole gaps to prevent disengagement of the clip in extremely high winds. The clip can be made to swivel for greater stability. A means for gripping the pole can be added to the clip, and also means for connecting the clips on one pole to clips on an adjacent pole may be provided. Other means of connecting the clips together in clusters can be used, such as using a cord to draw the clips together. The tongue and tongue slot may each be toothed on two sides rather than on only one side. The clips can be made of metal, wood, or any other slightly flexible material. The tongue may be hooked or may have a triangular, rounded, or elliptical cross section. The clips may be attached to the tent by cords that extend up from the tent below and are looped through holes in the clips. The clips may have arms that are barbed or pointed for insertion into a pocket or seam on the tent. The clips may have molded pierceable thin sections attached that are designed to be sewn directly to the tent.

Thus, the scope of the invention should be determined by the appended claims and their legal equivalents, and not by the examples given.
