DETAILED DESCRIPTION OF THE EMBODIMENT(S)
Embodiments of the present invention will be described hereinafter in detail with reference to the attached drawings, wherein like reference numerals refer to the like elements. The present invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided so that the disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art.
A zipper fastener system 1 according to the invention is shown in FIG. 1. Generally, the zipper fastener system 1 includes a first tape section 10, a second tape section 20, a first slider 30, and a second slider 40.
As shown in FIGS. 1-13, the first tape section 10 (having a first end and a second end) includes a first connection section 12, a first set of fastener elements 14, a first retainer box 16, and a first retainer pin 18b.
The first connection section 12 (having a first end 12a and a second end 12b) is a strip of tape that extends along a length thereof. The first connection section 12 can be attached to a first structure (not shown), such as a garment, textile, or other materials, using stitching, mechanical weld, or adhesive. In particular, the first connection section 12 is attached to the first structure (not shown) along a right side thereof. The second connection section 22 is attached to a second structure (not shown) along a left side thereof and is described in more detail below. Removable attachment of the first structure to the second structure is desirable or advantageous. For instance, in one embodiment of the invention, the first structure may be a sleeping bag, a hammock, or a tent. For instance, the second structure may be a second sleeping bag, a second hammock, a second tent, a net, a tarp, a travel bag, etc.
The first set of fastener elements 14 are teeth in the shown embodiment and are positioned along the length of the first connection section 12. The teeth of the first set of fastener elements 14 are positioned on a left side of the first connection section 12 and are generally parallel to each other. The teeth of the first set of fastener elements 14 extend away from the first connection section 12, substantially perpendicular to the length of the first connection section 12.
The fastener elements 14 of the zippers are of various types including those of nylon coil, or plastic, metal, or nylon teeth 19, 29. It is understood that “teeth” or “coil” are used interchangeably herein. The teeth collectively form a connection (zipper track). Each tooth 19, 29 includes a hollow 19a, 29a on one face and a hook 19b, 29b on the opposite face. Each zipper fastener system 1 includes two connection sections (or zipper tracks) of teeth which are latched together by operation of the sliders 30, 40. The sliders 30, 40 are independently moved along the two zipper tracks of uniformly sized and shaped teeth 19, 29. Wedge-shaped walls 35, 45 internal to the sliders 30, 40 respectively direct the two zipper tracks of teeth 19, 29 at an angle and into an interlocking relationship with each other. The zipper tracks are offset so that, in sequence, as the slider 30, 40 is drawn along the zipper tracks, a hollow 19a of one tooth on one zipper track aligns with a hook 29b of the tooth on the other zipper track as shown in FIGS. 4 and 13. The size of the zipper teeth is on the basis of the use to which the zipper fastener system will be subjected. Use of the zipper fastener system in camping equipment suggests a lightweight #3 gauge nylon coil zipper with a polyester tape and teeth that are water-, abrasion-, and UV-resistant and sliders made of molded plastic or metal, but one of ordinary skill in the art can select the particular material specifications to suit particular conditions.

Likewise, the second slider 40 moves along the second tape section 20 such that the second set of fastener elements 24 engages and connects with the first set of fastener elements 14. Accordingly, the first tape section 10 and second tape section 20 can be connected together and secured, or can be removed and separated from each other.
Likewise, in other shown embodiment, FIGS. 8-13, wherein the first and second retainer pins 18, 28 are located at opposite ends of the same tape section, 10 or 20, respectively, the first slider 30 is movably placed adjacent to the first retainer box 16 and the second retainer pin 28b is positioned through first slider 30 and into the first retainer box 16. As well, in this shown embodiment, the second slider 40 is movably placed adjacent to the second retainer box 26 and the first retainer pin 18b is positioned through second slider 40 and into the second retainer box 26.
After the first retainer pin 18b is positioned into the first retainer box 16 as described above, the first slider 30 moves along the first tape section 10 such that the first set of fastener elements 14 engages and connects with the second set of fastener elements 24. Likewise, after the second retainer pin 28b is positioned into the second retainer box 26 as described above, the second slider 40 moves along the first tape section 10 such that the second set of fastener elements 24 engages and connects with the first set of fastener elements 14. The first slider and second slider are independently moved by means of the inner or outer pull tabs along the first and second tape sections. Accordingly, the first tape section 10 and second tape section 20 can be connected together and secured, or can be removed and separated from each other.
Regardless of whether invention is operated having the first and second retainer pins 18b, 28b and the corresponding first and second retainer box 16, 26 located on the same tape sections, or in the alternative, wherein the first and second retainer pins 18b, 28b and the corresponding first and second retainer box 16, 26 are located on different tape sections, the first slider 30 and the second slider 40 can be movably positioned to engage and connect the first set of fastener elements 14 with the second set of fastener elements 24. The first slider 30 and the second slider 40 may be so positioned on first tape section 10 and second tape section 20 such that, as between the first set of fastener elements 14 and the second set of fastener elements 24, there is a passageway which can be varied in length in position along the first and second tape sections 10, 20. Alternatively, the first slider 30 and the second slider 40 may be so positioned adjacent to each other along the first and second tape sections 10, 20 such that there is no open passageway. The inner and outer pulls allow positioning of the sliders independently along the first and second tape sections as desired by the user from either outside the joined first and second structures or from within the joined first and second structures.

The tension devices 134 on opposite long edges 112, 114 are attached to groups of tension connectors 132 at opposite ends to create an extended diagonal portion of the hammock body 110, forming a tension axis 136 shown in FIGS. 16-19 extending at an angle with respect to the suspension axis 128. As shown in FIGS. 16-19, a user may thus lay flat in a diagonal orientation within the hammock 100.
As shown in FIGS. 15-19, the tension system 130 may be used interchangeably in various configurations to enable different diagonal laying orientations. In FIGS. 15-17, the tension devices 134 are attached to and tension a first set of tension connectors 132, forming the tension axis 136 at a first angle with respect to the suspension axis 128. In this orientation of the hammock 100, a user may lay in either a first position shown in FIG. 16 or a second position shown in FIG. 17. In FIGS. 18 and 19, the tension devices 134 are attached to and tension a second set of tension connectors 132, forming the tension axis 136 at a second angle with respect to the suspension axis 128. In this orientation of the hammock 100, a user may lay in either a third position shown in FIG. 18 or a fourth position shown in FIG. 19.
The cover 200, shown generally in FIG. 20, includes a cover body 210 having a first edge 212 and an opposite second edge 214 and is formed of a first material 216 and a second material 218.
Each of the first edge 212 and the second edge 214 has a curved shape as shown in FIG. 20 to match the hammock. The first edge 212 and the second edge 214 extend further from a cover longitudinal axis 220 at opposite longitudinal ends of the cover 200 to form a shape of the cover body 210 corresponding to the shape of the suspended and diagonally tensioned hammock 100 shown in FIG. 15.
As shown in FIG. 20, the first tape section 10 or the second tape section 20 of the zipper fastener system 1 is disposed along each of the first edge 212 and the second edge 214. In various embodiments, the first tape section 10 may be disposed along each of the first edge 212 and the second edge 214, the second tape section 20 may be disposed along each of the first edge 212 and the second edge 214, or any combination thereof. The tape sections 10, 20 may be attached to the edges 212, 214 by sewing, gluing, welding or any other means of attachment known to those with ordinary skill in the art. As described above and shown in the embodiments of FIGS. 6 and 9, the tape sections 10, 20 disposed on each of the first edge 212 and the second edge 214 may each have zero sliders 30, 40, one slider 30, 40, or two sliders 30, 40.
The first material 216 may be formed of nylon such as ARGON 90, cotton, silk, polyester, polypropylene, polyethylene, polytetrafluoroethylene, or any other durable, wind-resistant, water-resistant material known to those with ordinary skill in the art. The first material 216 may be reinforced with a ripstop pattern.
The second material 218, as shown in FIG. 20, is a netting formed of nylon, cotton, silk, polyester, polypropylene, polyethylene, or any other durable netting materials known to those with ordinary skill in the art. The netting of the second material 218 has a hole size sufficient to permit ventilation and visibility while preventing insect penetration such as NO-SEE-UM or NANO NO-SEE-UM netting.
In the embodiment of FIG. 20, the first material 216 forms a majority of cover body 210 while the second material 218 forms a minority of the cover body 210. The second material 218 is disposed at a longitudinal end of the cover body 210. One with ordinary skill in the art would understand that the relative percentages of the first material 216 and second material 218 constituting the cover body 210 may vary depending on the applications of the cover 200. In another embodiment, shown in FIG. 23, the cover body 210 may entirely comprise the second material 218.
The cover body 210, as shown in FIG. 20, has a first side 222 and an opposite second side 224. The first material 216 and the second material 218 constitute the same percentage of each side 222, 224 of the cover body 210.
A hammock assembly using the hammock 100 and cover 200 will now be described with reference to FIGS. 21-23.
The cover 200 is removably attached to the hammock 100 when the hammock 100 is in one of the suspended and tensioned positions shown in FIGS. 15-19. The cover 200 is positioned over the hammock 100 such that the shape of the cover body 210 corresponds to the shape of the suspended and tensioned hammock 100. As shown in FIGS. 21-23, the central suspension line 127 supports the cover 200 along the cover longitudinal axis 220 to create an enclosable space between the hammock 100 and the cover 200.
The cover 200 is removably attached to the hammock 100 by the zipper fastener system 1. The tape sections 10, 20 disposed on the cover 200 are those which mate with the tape sections 10, 20 disposed on the hammock 100; if first tape sections 10 are disposed on each of the long edges 112, 114 of the hammock 100, then tape sections 20 are disposed on each of the first edge 212 and second edge 214 of the cover 200, and vice versa. Each mating set of tape sections 10, 20 of the zipper fastener system 1 between the hammock 100 and cover 200 has a first slider 30 and a second slider 40. The first slider 20 and second slider 40, as shown in FIGS. 6 and 9, may be disposed on either the same tape section 10, 20 or on different tape sections 10, 20.
The attachment of the cover 200 to the hammock 100 will be described hereinafter with reference to the embodiment of the zipper fastener system 1 shown in FIGS. 1-8, with the first tape section 10 disposed on the first long edge 112 and the second long edge 114 of the hammock 100, and the second tape section 20 disposed on the first edge 212 and the second edge 214 of the cover 200. One with ordinary skill in the art would understand that other configurations of the zipper fastener system 1 described above, such as the embodiment of FIGS. 9-13 or a reversal of the tape sections 10, 20 between the hammock 100 and cover 200, are also possible.
As shown in FIG. 21, with the hammock 100 in a first orientation due to the tension system 130, the first side 222 of the cover 200 faces in a vertical direction and the second long edge 114 of the hammock 100 having the first tape section 10 is aligned with the second edge 214 of the cover 200 having the second tape section 20. As shown in detail in FIGS. 1-8, the first slider 30 is movably attached to the first retainer box 16 of the first tape section 10 attached to the hammock 100. The second retainer pin 28b of the second tape section 20 attached to the cover 200 is positioned through the first slider 30 and into the first retainer box 16. Likewise, the second slider 40 is movably attached to the second retainer box 26 of the second tape section 20 and the first retainer pin 18b of the first tape section 10 is positioned through the second slider 40 and into the second retainer box 26.
The first slider 30 moves along the first tape section 10 of the hammock 100 such that the first set of fastener elements 14 of the first tape section 10 engages and connects with the second set of fastener elements 24 of the second tape section 20 of the cover 200. Likewise, the second slider 40 moves along the second tape section 20 such that the second set of fastener elements 24 engages and connects with the first set of fastener elements 14. Accordingly, the first tape section 10 of the hammock 100 and second tape section 20 of the cover 200 can be connected together and secured, or can be removed and separated from each other, connecting the second long edge 114 of the hammock 100 with the second edge 214 of the cover 200.
Further, with the hammock 100 in the first orientation shown in FIG. 21, the first long edge 112 of the hammock having the first tape section 10 is aligned with the first edge 212 of the cover 200 having the second tape section 20. The removable attachment of the first tape section 10 and second tape section 20, and correspondingly the removable attachment of the first long edge 112 of the hammock 100 with the first edge 212 of the cover 200, is the same as described above with respect to the second long edge 114 of the hammock 100 and the second edge 214 of the cover 200.
The cover 200 is thus removably attached to the hammock 100 by the zipper fastener system 1 connecting two aligned sets of edges 112, 212 and 114, 214. The zipper fastener system 1 used on each set of edges 112, 212 and 114, 214 allows a user to enter and exit the enclosed space between the hammock 100 and cover 200 from either side. The first slider 30 and the second slider 40 meet in the middle of each set of edges 112, 212 and 114, 214 and each have both an outer pull tab 34, 44 and an inner pull tab 36, 46, and consequently, may be used to create variably sized openings and are more easily manipulated by a user from either inside or outside the enclosed space of the hammock 100 and cover 200.
The zipper fastener system 1 also allows other configurations of the hammock 100 and the cover 200. As shown in FIG. 15, because the first tape portions 10 and the second tape portions 20 are separately secured to the hammock 100 and cover 200, the cover 200 is completely removable from the hammock 100. Different embodiments of covers 200 may also be interchangeably attached to the hammock 100. As shown in FIGS. 21 and 22, a cover 200 having the first material 216 and the second material 218 may be attached to the hammock 100. In an exemplary embodiment, the cover 200 shown in FIGS. 21 and 22 is used in cold weather applications as the first material 216 provides wind protection and warmth while the second material 218 constitutes a sufficient percentage of the cover body to permit adequate ventilation for the enclosed space. Alternatively, as shown in FIG. 23, a different embodiment of the cover 200 is interchangeably attached to the hammock 100 in warm weather having only the second material 218 for insect protection.
The cover 200 is also adaptable to different laying orientations and tension axes 136 of the hammock 100. As shown in FIGS. 16 and 17, the user may lay in either the first position or the second position in the first orientation of the tension axis 136. The cover 200 can be attached to the hammock 100 with the first side 222 facing in the vertical direction as shown in FIG. 2 and the second material 218 at either end of the hammock 100, and consequently, the user can position the ventilating second material 218 over an end at which the user's head is positioned. Further, if the user changes the tension axis 136 from the first orientation shown in FIGS. 16 and 17 to the second orientation shown in FIGS. 18 and 19, the cover 220 is reversible and can be attached at either end of the hammock 100 with the second side 224 facing in the vertical direction, as shown in FIG. 22.
The foregoing illustrates some of the possibilities for practicing the invention. Many other embodiments are possible within the scope and spirit of the invention. It is, therefore, intended that the foregoing description be regarded as illustrative rather than limiting, and that the scope of the invention is given by the appended claims together with their full range of equivalents.
