The present disclosure relates generally to portable shelters. More particularly, it relates to a fastening system or connector construction for securing such shelters to each other, in particular, connecting the fabric coverings of such shelters together.
In the past, a wide variety of portable shelters have been used. These include tents and similar structures, as well as inflatable structures, geodesic domes and various types of prefabricated shelters. Tents have the advantages of being inexpensive, quickly erectable, portable, and generally lightweight. They are generally easily assembled, disassembled and stored when disassembled. In short, tents and portable structures of varying designs have many uses. The present disclosure is suitable for a wide variety of recreational, military and business uses whenever a sturdy, yet quickly erectable portable shelter is needed.
It is often advantageous to join or connect two or more shelters to each other or to separate them from one another as may be necessary to accomplish a particular task. A common way to join fabric shelters or tarps is to use becket lace (a short loop of rope with a knot at one end) and grommets. A traditional becket lace fastening system or connector construction has lace located on one side edge of the fabric material covering a shelter and grommets located on the other side edge of the material. However, some designs only have lace on both side edges of a strip of shelter or tarp material and beckets only on the side edges of another strip of material of the shelter or tarp meant to be connected to the first strip. If two shelters only have lace or only have beckets, the connection cannot be made. Another difficulty with becket lace-type arrangements is that at the end of the becket lace, the last two loops are knotted so that the lace cannot be pulled apart. However, often times, someone assembling such a shelter will let go of one of the loops and the whole section unlaces due to the weight of the fabric pulling on the lace. Becket lace connector constructions are also personnel intensive and require a significant amount of time to accomplish.
Other methods of connecting segments of a shelter fabric material include zippers and standard hook and loop (VELCRO®) fasteners or fastening elements. However, zippers can be difficult to start. Also, it is difficult to fasten a zipper connection on adjacent panels of the fabric so that the panels stay aligned. Zippers also break easily. A difficulty with conventional hook and loop fasteners is that a single connection joint can be pulled apart easily. Moreover, hook and loop fasteners require that the correct mating sections be installed on each panel side edge, i.e., a strip of hook material or a strip of loop material. But, since hook material does not connect to hook material, and loop material does not connect to loop material, one side edge of the shelter fabric needs to have a strip of hook material and the other side edge needs to have a strip of loop material. If one side edge of a shelter has hooks on its side edge, then the mating shelter would need to have loops on the edge which is meant to be secured thereto, and vice versa.
However, this requires the two shelters to be built differently and arranged in a particular order, both of which requirements are highly undesirable. To make them the same, one would need to manufacture all the shelter segments so that one side edge would have hook connectors and the other side edge would have loop connectors. But, if this is done, the user has to take care to set up the shelters for ready connection. If loops are facing loops or hooks are facing hooks, the shelter would need to be rotated 180° to align it with an end edge of an adjacent tent. Because shelters can be difficult to set up, rotating them to adjust their alignment with each other is problematic. For example, some of these tents, such as tents used by the military as well as by emergency response teams, weigh over 700 pounds each. Rotating a 700 pound tent is difficult, time consuming and requires multiple personnel. Moving such tents can also lead to damage when done by the untrained.
It would therefore be desirable to provide a shelter interengagement system or connector assembly which is universal so that any shelter can be secured to any other shelter, whether the open sidewalls of two shelters are connected to each other or via interconnected doorways of the two shelters. It would also be desirable to provide a connector assembly that is easy to use, is sturdy and requires a minimum number of personnel to use. Further, it would be desirable to provide a connector assembly that can be employed to connect any desired number of shelters to each other.
In accordance with one aspect of the present disclosure, a connector assembly for interlocking adjacent members includes a first Y-shaped connector affixed to a portion of a first member, a second Y-shaped connector affixed to a portion of a second member, wherein each of the first and second Y-shaped connectors includes a first arm with an outer face and an inner face and a second arm with an outer face and an inner face. A loop-type engaging element is mounted on one of: (i) the inner faces of both the first and second arms of each of the first and second Y-shaped connectors; (ii) the outer faces of both the first and second arms of each of the first and second Y-shaped connectors. A hook-type engaging element mounted on the other of: (i) the inner faces of both the first and second arms of each of the first and second Y-shaped connectors; (ii) the outer faces of both the first and second arms of each of the first and second Y-shaped connectors. Each of the first and second Y-shaped connectors is selectively configurable to either a male configuration or a female configuration and an interlocking connection between the first member and the second member is made when one of the first and second Y-shaped connectors is arranged in the male configuration and the other of the first and second Y-shaped connectors is arranged in the female configuration, and the engaging elements on the inner faces of the first and second arms of the Y-shaped connector in the female configuration are respectively lockably engaged with the engaging elements on the outer faces of the first and second arms of the Y-shaped connector in the male configuration.
According to another aspect of the present disclosure, a shelter covering with connectible ends includes a fabric material including a first end and an opposite second end. A first Y-shaped connector is mounted on the fabric first end and a second Y-shaped connector mounted on a fabric second end. The first and second Y-shaped connectors are identical and each of the first and second Y-shaped connectors comprises a first arm having outer and inner faces and a second arm having outer and inner faces. A loop material is mounted on one of: (i) the inner faces of both the first and second arms of each of the first and second Y-shaped connectors; (ii) the outer faces of both the first and second arms of each of the first and second Y-shaped connectors. A hook material mounted on the other of: (i) the inner faces of both the first and second arms of each of the first and second Y-shaped connectors; (ii) the outer faces of both the first and second arms of each of the first and second Y-shaped connectors. Each of the first and second Y-shaped connectors is selectively configurable so that the first and second arms thereof are spaced apart to form a female connector or brought adjacent each other to form a male connector.
According to still another aspect of the present disclosure, a method of interlocking adjacent members includes providing a first Y-shaped connector affixed adjacent a first end of a first member and a second Y-shaped connector affixed adjacent a second end of a second member. Each of the first and second Y-shaped connectors includes a first arm with an outer face and an inner face, and a second arm with an outer face and an inner face. Each of the outer faces includes one of a loop-type engaging element and a hook-type engaging element, and each of the inner faces including the other of a loop-type engaging element and a hook-type engaging element. A male configuration is formed from the first and second arms of the first Y-shaped connector by locating the first and second arms of the first Y-shaped connector adjacent each other, and a female configuration is formed from the first and second arms of the second Y-shaped connector by locating the first and second arms of the second Y-shaped connector to be spaced-apart from each other. The first end of the first member is placed adjacent to the second end of the second member so that the first and second ends are aligned with each other. The male configuration of the first Y-shaped connector is inserted between the spaced-apart first and second arms of the female configuration of the second Y-shaped connector such that the engaging elements located on the outer faces of the first and second arms of the first Y-shaped connector are located adjacent the engaging elements located on the inner faces of the first and second arms of the second Y-shaped connector. The engaging elements located on the outer faces of the first and second arms of the first Y-shaped connector are lockably engaged with the engaging elements located on the inner faces of the first and second arms of the second Y-shaped connector, thereby interlocking the first and second ends of the first and second members.
Among the advantages of the use of Y-shaped connectors mounted on opposite ends of a shelter covering are the durability of the connection so formed and the convenience of operation. The interengaging connectors according to the present disclosure provide a releasable connection between sheet members which connection increases in strength as the tension upon the joint members increases. Put another way, it is difficult to separate two adjacent shelter covers which have been connected via the interengaging Y-shaped connectors, as they provide two separate but adjacent parallel connections or joints, wherein each joint comprises a hook and loop fastening element. The Y-shaped connectors can be sewn or welded around the outside perimeter of a doorway when two shelters are joined at doorways. Alternatively, two open ended shelters can be joined together via Y-shaped connectors installed around the facing edges of two shelters thus providing an open ended connection. Thus, the Y-shaped connectors can be used to join shelters together in an open end style or at doorways.
The present disclosure may take physical form in certain parts and arrangements of parts, several embodiments of which will be described in detail in this specification and illustrated in the accompanying drawings which form a part hereof and wherein:
Referring now to the drawings wherein the showings are for purposes of illustrating several embodiments only and are not intended to limit same,

Thus, defined is a first connector element 59 located along one side edge of the first cover 34. The first arm A1 of the connector element 59 includes an outer face 60 (which comprises the outer face of the cover 34) on which there is provided a layer or strip of loop material 62 (also referred to herein simply as a “loop element” or a “loop-type engaging element”) of a hook-and-loop fastening element. One suitable hook-and-loop fastening element is available commercially under the trademark VELCRO®. The layer or strip of loop material 62 is fastened or secured to the material of the cover 34 on the outer face 60 of the first arm A1. The first arm A1 also includes an inner face 64 provided by a first end inner face of the flap 52 on which there is provided or positioned a layer or strip of hook material 66 of a hook-and-loop fastening element (also referred to herein simply as a “hook element” or a “hook-type engaging element”). The second arm A2 includes an inner surface or inner face 68 provided by an inner surface of the second end of the flap 52 on which is provided a layer or strip of hook material 70, and the second arm A2 includes an outer surface or outer face 74 provided by an outer surface of the second end of the flap 52 on which is provided a layer or strip of loop material 76. The hook material and loop material can be secured or fastened to the first and second arms A1,A2 (i.e., to the first cover 34 and the first flap 52) via stitching or other known fastener or fastening constructions such as adhesive or ultrasonic welding or the like. A view of the first connector element 59 by itself is illustrated in
Located on the adjacent edge of the second cover 44 is a second connector element 78 that is identical to the first connector element 59 but oriented in a mirror-image fashion relative to the first connector element 59. The first arm A3 of the connector element 78 includes an outer face 80 (which comprises the outer face of the cover 44) on which there is provided a layer or strip of loop material 82 of a hook and loop fastening element. The layer or strip of loop material 82 is fastened or secured to the material of the cover 44 on the outer face 80 of the first arm A3. The first arm A3 also includes an inner face 84 provided by a first end inner face of the flap 54 on which there is provided or positioned a layer or strip of hook material 86 of a hook and loop fastening element. The second arm A4 includes an inner face 88 provided by an inner face or inner surface of the second end of the flap 54 on which is provided a layer or strip of hook material 90, and the second arm A4 includes an outer surface or outer face 94 provided by an outer surface of the second end of the flap 54 on which is provided a layer or strip of loop material 96. The hook material and loop material can be secured or fastened to the first and second arms A3,A4 (i.e., to the first cover 44 and the flap 54) via stitching or other known fastener or fastening constructions such as adhesive or ultrasonic welding or the like. Here, again, it should be noted that the positions of the hook elements 86,90 can be respectively exchanged with the positions of the loop elements 82,96 without departing from the scope and intent of the present development, provided that the respective inner faces 84,88 of the first and second arms A3,A4 include like elements of a first type (either hook elements or loop elements) and the respective outer faces 80,94 of the first and second arms A3,A4 also include like elements of a second type (either hook elements or loop elements), and provided that the first connector 59 and second connector 78 are correspondingly structured with the hook elements and loop elements thereof located in the same relative positions.
In order to seal out weather and to seal in light (such as for military blackout conditions), the first and second connector elements 59 and 78 can run continuously around the perimeter of the adjoining ends of the respective shelters 30 and 40, i.e., at least along the walls and roof. This can be seen in
In one embodiment, the connector elements 59 and 78 could be made first and then attached to the shelter fabric 34,44. In another embodiment, the connector elements 59,78 could be formed by sewing the necessary components to the shelter fabric 34,44, all at the same time. One difficulty in sewing such layers to each other is that trying to sew more than two layers at a time has been found difficult. Thus, in one embodiment, the flap 52,54 and its layers of hook and loop material will be manufactured first and then the connector element would be finished while the flap is being sewn to the shelter.
As described in more detail below, each Y-shaped connector 59,78 is configurable to be in either a male configuration as shown for the connector 78 or a female configuration as shown for the connector 59. In the male configuration as shown for the connector 78, the arms A3,A4 are arranged proximate each other such that the engaging elements 82,96 on the outer surfaces 80,94 are exposed and face outwardly. In the female configuration as shown for the connector 59, the arms A1,A2 are arranged spaced-apart relative to each other such that the engaging elements 66,70 on the inner surfaces 64,68 are exposed and face inwardly toward each other. In use, the shelters 30,40 are each constructed to include the Y-shaped connectors 59 and 78 at the opposite ends of each shelter such that each connector 59,78 can extend continuously and coextensively with the cover 34,44. The shelters 30,40 are joined in an end-to-end arrangement by mating the connectors 59,78 as shown in

While
The connector constructions disclosed herein significantly reduce and, perhaps completely prevent, the ingress of sand, dust, rain, precipitation, moisture, melting snow, water runoff, water from the ground, flying or crawling insects and animals into the connected shelter construction. As mentioned, the connector construction also serves to block the emission of light at the connection between two shelters. Further, the connector construction is strong so that the two shelters will stay connected until it is desired to disconnect them from each other.
With reference now to
With reference now to
It is contemplated that a shelter construction of the type illustrated herein could be provided with both the Y-shaped connector disposed around the periphery of the door opening as shown in
It should be appreciated that the connector assembly disclosed herein forms a double layer or double joint of hook and loop connections between adjacent shelters or between adjacent panels of fabric material constituting the covering on a shelter. Thus, a sturdy connection can be made between adjacent shelters and in a much faster manner than with the prior art becket lace and grommet shelter connection structures. Further, it takes much less manpower to form the connection between two shelters. A connector assembly as disclosed herein is more difficult to separate than pulling apart a single hook and loop-type connection. A connector assembly as disclosed herein is useful for the purpose of joining shelters together either at doorways using a connection 210 as shown in
It should be appreciated that the first and second Y-shaped connectors are identically disposed on the first and second ends of the fabric material constituting the roof and sidewalls of a shelter. Alternatively, a Y-shaped connector can be affixed to an end wall of a shelter structure and disposed around the perimeter of a doorway defined in the shelter structure.
The connector assembly disclosed herein can be secured to a variety of conventional fabrics employed for shelters. In most cases, the fabric would meet military standards for strength, mildew resistance, light penetration and the like. However, none of these is a requirement for making the connector assembly work.
One advantage of the connector assembly illustrated herein is that the connector assembly is universal and ambidextrous or hermaphroditic. It allows the exact same Y connector to be installed adjacent both side edges of each of two shelters or adjacent the doors of two shelters. No matter which two openings or shelters are connected, the connector assembly from one side will connect to the connector assembly on the other side, without regard to the orientation of the shelters relative to each other. Thus, the shelters don't have to be rotated in order to be connected to each other.
Another advantage of the connector assembly according to the present disclosure is that the connector construction can be made to be either male or female as may be desirable. Because all connections are identical, a user need not worry about having the correct connector in order to secure two shelters to each other. Further, using the hook and loop arrangement disclosed herein, the two sections or two shelters are firmly connected as soon as the two connector assemblies are pressed together. This eliminates the problem with the prior art of the becket lace pulling apart if one lets go of the lace.
Further, one or more shelters can be connected to any other shelter without the use of any additional equipment and without excess handling of the connection structure. Furthermore, the connector construction disclosed does not require a connector of one type to be located on one shelter and a connector of a second type to be located on the other shelter. Thus, all shelters are readily interconnectable.
While the connector construction or system disclosed herein has been described in connection with a shelter, it should be appreciated that the connector system can be employed in a variety of other fabric assemblies. These include tarps, awnings, flexible flanges on rigid panels, as well as the types of tarps or fabric coverings used on truck trailers.
The exemplary embodiments of the present disclosure have been described with reference to several drawings. Obviously, modifications and alterations will occur to others upon a reading and understanding of the preceding detailed description. It is intended that the disclosure not be limited to the embodiments described. Rather, the present disclosure should be construed as including all modifications and alterations which come within the scope of the appended claims or the equivalents thereof.
This application claims the benefit of Provisional Application Ser. No. 62/211,068 which was filed on Aug. 28, 2015, and the entire content of said provisional application is incorporated hereinto by reference.
