This disclosure relates generally to a single piece hammock strap with integral woven eyelets. More specifically, the hammock strap disclosed herein is useful in outdoor applications, such as, for example, supporting a hammock.
Many outdoor activities require that participants camp overnight in order to fully enjoy a chosen work or recreational activity. However, camping, in many cases, is substantially less comfortable than sleeping in a bed. This lack of comfort can lead to restless sleeping, poor rest, and general fatigue, lessening the overall enjoyment of the chosen work or recreational activity for which the participants camped overnight in the first place.
Tents, sleeping pads, tarps, makeshift shelters, recreational vehicles, and other sleeping implements increase the ability of participants in outdoor activities to enjoy spending the night in the outdoors. However, these exemplary sleeping implements are not practical for use in many situations. For example, a hiker on a backpacking trip must carry tools with which to construct a shelter or the shelter itself (i.e., a tent) to the place in which the hiker intends to camp. Carrying either tools or a tent, however, presents other difficulties.
For example, when campers do not have access to a vehicle while camping, and sometimes even when campers do have access to a vehicle, a camper can be limited in the equipment that can be brought because of both excessive weight and excessive bulk. While many would consider a bed to be more comfortable to sleep in than a tent, most campers cannot carry a bed to a camping spot because the bed is too heavy to practically carry. Similarly, some tents may also be too heavy to carry when a camper considers the other items the camper must bring to increase comfort while camping. Excessive bulk is better described in terms of volume. For example, a camper may use a pack that has a finite volume and that can only hold camping comfort items of a specific size. Some camping comfort items, while not necessarily heavy, require a substantial amount of space within a pack. Thus, a camper must carefully balance the gear that can or should be brought camping with the amount of weight that can be carried and the available space in which the gear can be carried.
Hammocks have conventionally been reliable to increase camper comfort during an overnight outdoor activity while also being relatively light and relatively compact, compared to a tent, for example. The main drawback of a hammock is finding a suitable area in which to hang the hammock. In order for a camper to use the hammock under conventional conditions, a camper must find two fixed structures, such as trees, that are appropriately spaced and large enough to support the weight of the camper in the hammock. Conventionally, hammock campers use rope to tie each end of a hammock to a tree at an appropriate height. However, many times, the rope used to tie each end of a hammock slips or slides down the tree, resulting in the camper dropping to the ground. Under conventional conditions, campers would find trees with branches at an appropriate height that would prevent a tie rope from sliding down a tree. Frequently, however, other branches on the tree would have to be cut to allow the camper to stretch a tie rope around a tree. This resulted in substantial damage to trees in popular camping areas.
In response to this arboreal damage caused by campers with hammocks, many states passed laws preventing campers from damaging live trees by hanging hammocks. Accordingly, attempts were made to provide hammock tie down attachments that do not cause damage to trees. One such attempt is described in U.S. Pat. No. 9,003,579, which describes a hammock support strap. Essentially, this hammock support strap provides a plurality of hook points that are folded over on each other and sewn into the strap using stitching. When one looped end of the strap is inserted in another looped end of the strap, the strap cinches down on a tree without damaging the tree. The camper may attach a hammock to one of the hook points along the length of the strap. These folded over portions of the strap provide adequate strength to support a camper's weight within the hammock.
At the same time, however, conventional hammock straps, such as the one described above, require substantial stitching by skilled seamster, which increases production costs. More problematic, however, is that the folding portion of the hooks to provide adequate strength to support a camper's weight in the hammock also substantially increases the overall bulk of conventional straps. In other words, the folded over portion of the hooks along the strap, by its very nature creates more undesirable bulk because the folds increase the overall space required to contain the strap during transport to and from a camping site.
It is therefore one object of this disclosure to provide a hammock strap useful in, but not limited to, attaching a hammock to a fixed structure, such as a tree. Another object of this disclosure is to provide a hammock strap that reduces weight and bulk. Finally, an object of this disclosure is to provide a method of making a hammock strap.
Disclosed herein is a hammock strap. The hammock strap includes an elongated length of flexible strap material that is separated into a first strap and a second strap. The first strap and the second strap are woven together at one or more separation points to form one or more eyelets between the first strap and the second strap.
Further disclosed herein is a method of making a hammock strap. The method includes weaving one or more fibers together to form an elongated length of flexible strap material. The elongated length of flexible strap material may be separated into a first strap and a second strap at a first separation point. Further, one or more fibers in the first strap are woven into one or more fibers in the second strap at a second separation point, thereby forming an eyelet in the hammock strap.
The accompanying drawings illustrate an embodiment of a hammock strap.
In the following description, for purposes of explanation and not limitation, specific techniques and embodiments are set forth, such as particular techniques and configurations, in order to provide a thorough understanding of the hammock strap disclosed herein. While the techniques and embodiments will primarily be described in context with the accompanying drawings, those skilled in the art will further appreciate that the techniques and embodiments may also be practiced in other similar apparatuses.
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used throughout the drawings to refer to the same or like parts. It is further noted that elements disclosed with respect to particular embodiments are not restricted to only those embodiments in which they are described. For example, an element described in reference to one embodiment or figure, may be alternatively included in another embodiment or figure regardless of whether or not those elements are shown or described in another embodiment or figure. In other words, elements in the figures may be interchangeable between various embodiments disclosed herein, whether shown or not.
Hammock strap 100 may be woven from these synthetic fibers such that hammock strap 100 begins with an elongated section 135 of flexible strap material between loop 125 and an eyelet 120n. Hammock strap 100 terminates on an eyelet end 110a and fixed end 110b hammock strap 100. In general, terminating hammock strap 100 at eyelet end 110a may be a result of either sewing strap portion 105 to an eyelet strap portion 115 or, alternatively, weaving fibers from strap portion 105 into fibers from eyelet strap portion 115 to create loop 130. Terminating hammock strap 100 at fixed end 110b may also be a result of either sewing an elongated section 135 of flexible strap material back on itself or, alternatively, weaving fibers from an elongated section 135 of flexible strap material back into itself at another point on elongated section 135 of flexible strap material to create loop 125b. The termination of hammock strap 100 will be further discussed below.
Hammock strap 100 may be constructed as a single piece. For example, while synthetic fibers are being woven together to create hammock strap 100, the synthetic fibers may be separated such that a strap portion 105 and an eyelet strap portion 115 are woven as individual straps from the elongated section 135 of flexible strap material. More simply, the thickness (or alternatively the width) of hammock strap 100 may be divided in half such that strap portion 105 and eyelet strap portion 115 become separate lengths of flexible strap material which are re-connected at various points along hammock strap 100. After a desired length of flexible strap material is created for both strap portion 105 and eyelet strap portion 115, strap portion 105 and eyelet strap portion 115 may be rejoined together at a separation point, such as separation point 115a. Separation points 115a, 115b, 115c, 115d to 115n refer to points along hammock strap 100 where the separated strap portion 105 and the separated eyelet strap portion 115 may be woven together and re-separated successively to form eyelets 120a, 120b, 120c, 120d to 120n. Accordingly, hammock strap 100 is woven such that hammock strap 100 may be divided into a strap portion 105 and an eyelet strap portion 115 that may be selectively rejoined into hammock strap 100 at two or more separation points (e.g., 115a and 115b) along the length of hammock strap 100, forming one or more eyelets (e.g., 120a)
As shown, n number of separation points 115a-115n may join and separate, by selectively interweaving, strap portion 105 to/from eyelet strap portion 115, although preferable implementations will include between 2 and 15 separation points 115a-115n. Separation points 115a-115n each form a corresponding eyelet 120a, 120b, 120c, 120d, to 120n between strap portion 105 and eyelet strap portion 115. Since eyelets 120a-120n are formed by separation points 115a-115n, and n number of separation points 115a-115n may be implemented along strap portion 105 using eyelet strap portion 115, n number of eyelets may also be implemented between strap portion 105 and eyelet strap portion 115. As before, however, preferable implementations of hammock strap 100 will include between 2 and 15 eyelets 120a-120n between strap portion 105 and eyelet strap portion 115. In contrast to eyelets 120a-120n, eyelet end 110a and fixed end 110b of hammock strap 100 are terminated using loop 125 and loop 130. Loops, herein, are distinguished from eyelets in that loops are created in eyelet end 110a and fixed end 110b by sewing using a series of sewing stitches referred to as a bartack or by interweaving the elongated section 135 of flexible strap material back on itself or to eyelet strap portion 115, as described above. A bartack stitch, as used herein, means any number of individual stitches that connect one section of a strap to another section of a strap across substantially the entire width of the strap.
Loop 125 on fixed end 110b is shown in
In practice, strap portion 105 and eyelet strap portion 115 are separated from each other by altering the weaving technique used to create hammock strap 100. Strap portion 105 and eyelet strap portion 115 begin as a single elongated section 135 of webbing, for example, that forms hammock strap 100. The length of eyelet strap portion 115 may vary depending on the number of eyelets 120a-120n that are created by interweaving strap portion 105 and strap portion 115. In one embodiment, eyelet strap portion 115 is separated from strap portion 105, forming a first one of separation points 115a-115n. In this embodiment, a second one of separation points 115a-115n is again created by weaving eyelet strap portion 115 into strap portion 105 and then re-separating eyelet strap portion 115 from strap portion 105. Along strap portion 105, a length of flexible strap material between the first one of separation points 115a-115n and the second one of separation points 115a-115n is less than a length of flexible strap material between the first one of separation points 115a-155n and the second one of separation points 115a-155n along eyelet strap portion 115. Thus, because there is a longer portion of webbing between two separation points along eyelet strap portion 115 than there is between the two separation points along strap 105, an eyelet 120a-120n is formed between the two separation points on hammock strap 100. Further separation points 115a-115n are similarly formed until the desired number of eyelets 120a-120n are created along hammock strap 100. In one embodiment, the sizes of each eyelet 120a-120n are consistent along the length of hammock strap 100. As mentioned above, when the desired number of eyelets 120a-120n is achieved by weaving an appropriate number of separation points 115a-115n, strap portion 105 and eyelet strap portion 115 are sewn together using bartack stitching or woven together to form loop 130 at eyelet end 110a. Similarly, loop 125 is formed by sewing an end of strap portion 105 back into itself or weaving an end of strap portion 105 back into itself to form fixed end 110b. Accordingly, hammock strap 100 is formed.
The weaving/separating of strap portion 105 and eyelet strap portion 115 at separation points 115a-115n provides a number of advantages. First, weaving fibers of eyelet strap portion 115 into the fibers of strap portion 105 is typically performed by a machine, which reduces labor and production costs when compared to conventional straps. Second, weaving strap portion 105 and eyelet strap portion 115 at separation points 115a-115n provides a connection that is stronger than conventional straps that are folded over and manually sewn together. Third, weaving strap portion 105 and eyelet strap portion 115 at separation points 115a-115n provides a mechanical connection point between the fibers of strap portion 105 and the fibers of eyelet strap portion 115, which substantially maintains the original breaking strength of the material, for example webbing, that is used to construct hammock strap 100. This mechanical connection between the fibers of strap portion 105 and the fibers of eyelet strap portion 115 is superior to other methods of connection such as heat welding, sonic bonds, adhesive based connections, metal fasteners, or other methods of connecting straps that are known in the art. These other methods of connection are more likely to fail under pressure or a load because these other methods of connection have a much lower breaking strength than, for example, the webbing itself. For example, the breaking strength of heat welding, sonic bonds, or adhesive based connections, relies on the strength of the weld, the bond, the adhesive, or other connections to maintain the connection. Frequently, the breaking strength of heat welding, sonic bonds, adhesive based connections is drastically lower than the breaking strength of the webbing itself introducing failure points at the connections. Thus, because the strength of a woven connection maintains substantially the same breaking strength as the original strap, failure points are eliminated. Thus, a woven connection is superior to these other methods of connection.
While conventional folded over and sewn connections are fairly strong, these connections add additional undesirable bulk to the strap. A woven strap eliminates the bulk created by folded over and sewn connections. For example, a folded and sewn connection in a strap increases the thickness of the strap at the fold to over three times the thickness of the initial strap, when the stitching is included in the overall thickness of the strap at the fold. The thickness of the woven connection at separation points 115a-115n is the same thickness of hammock strap 100 from which strap portion 105 and eyelet strap portion 115 are separated.
As used herein, the term weaving means interconnecting one or more fibers to either form a flexible strap material or to interconnect one or more fibers of one section of a strap with one or more fibers of another section of a strap. Fibers, which form one strap portion, are integrally wrapped around or between fibers from another strap portion in a manner that fastens the two sections of strap together in a permanent fashion. Weaving should not be confused with sewing in which one or more threads that do not make up any portion of a strap to be connected to another is successively inserted through two or more layers of strap material by a needle to form sewn stitches (i.e., sewn by a machine using one or more sewing threads in a chain stitch, a lockstitch, an overlock stitch, or coverstitch.)
In practice, hammock strap 100 may be used to support a load at any height by connecting the load to any one of eyelets 120a-120n. For example, hammock strap 100 may be attached to a fixed structure, such as a tree, by wrapping hammock strap 100 around a tree. Eyelet end 110a may be inserted through loop 125 in fixed end 110b and pulled such that loop 125 surrounds hammock strap 100. Pulling on eyelet end 110a therefore tightens hammock strap 100 around the exemplary tree. Once hammock strap 100 is tightened to the exemplary tree, each of the individual eyelets 120a-120n or loop 130 become points at which a load may be connected to hammock strap 100. In other words, each of the individual eyelets 120a-120n or loop 130 allow a load to be attached at a particular height along hammock strap 100. For example, if a user wished to attach a load as low to the ground as possible once hammock strap 100 is tightened around an exemplary tree, the user may attach the load to loop 130. If, alternatively, a user wished to attach a load as high above the ground as possible once hammock strap 100 is affixed to an exemplary tree, the user may attach the load to eyelet 120n. Similarly, the user may adjust the height of a load supported by hammock strap 100 as appropriate for any application by attaching the load to any of eyelets 120a-120n or loop 130. In another embodiment, hammock strap 100 may include an elongated section 135 between loop 125 and eyelet 120n that accommodates a large diameter tree. Thus, when hammock strap 100 is attached to a tree, elongated section 135 may allow each of eyelets 120a-120n to be accessible in that each one of eyelets 120a-120n passes through loop 125 before hammock strap is tightened to the tree.
While applications for use of hammock strap 100 abound, in one embodiment, two of hammock straps 100 may be used to provide anchor points for a hammock. Since a user may select any eyelet 120a-120n along the length of hammock strap 100 as an attachment point for a hammock, the user may have a much wider range in which acceptable fixed structures may be located to secure a hammock. Further, the user may choose to angle one end of the hammock to be higher than another by attaching, for example, a hammock to eyelet 120a on one of hammock strap 100 while attaching a second end of a hammock to loop 130 on a second hammock strap 100. Other exemplary uses for hammock strap 100 include securing a water vessel at a height suitable for cooking or bathing, securing food or other wildlife attractants in the air between trees, or securing a pack off the ground.
In order to further reduce the bulk and weight of hammock strap 400, hammock strap 400 may be tapered in an elongated section of hammock strap 400 between loop 425a and eyelet 420n, corresponding to elongated section 135 shown in
In order to further reduce the bulk and weight of hammock strap 500, the elongated section of hammock strap 500 may be tapered between loop 525a and eyelet 520n by taper 530. Taper 530, as discussed above with respect to taper 430 in
