DETAILED DESCRIPTION
Applicant recognized that there are problems associated with conventional attachment systems used to secure objects together. In particular, Applicant recognized that with some conventional cord attachment systems, it is difficult to adjust the tension in the cord. If there is insufficient tension in the cord, the attachment system may fail to keep the objects together. Applicant further recognized that with some conventional attachment systems, it is difficult to connect and/or disconnect portions of the attachment system to the cord.
Accordingly, aspects of the present invention are directed to a cord attachment system that permits adjustment of the tension in the cord. The attachment system may be configured such that the tension in the cord may be adjusted after the attachment system is coupled to multiple objects. As set forth in greater detail below, according to one embodiment, a cord tensioner is provided, and the cord tensioner may be positioned at one end of the attachment system. The cord tensioner is a component that receives a portion of the cord and is configured to grip or hold the cord to maintain the tension in the cord. The tension in the cord may be adjusted by varying the position of the cord in the tensioner.
Further aspects of the present invention are directed to an attachment system with a fitting that is configured to be easily connected and/or disconnected to the cord. As set forth in greater detail below, according to one embodiment, an attachment system is provided with a first fitting configured to couple a first working component to a first portion of the cord, and a second fitting configured to couple a second working component to a second portion of the cord.
Turning now to the figures, FIGS. 1A-1B are perspective views of one embodiment of an attachment system 200 configured to couple a first object to a second object. The attachment system 200 illustrated in FIGS. 1A-1B includes a cord 10, and a fastener 40 coupled to the cord. The fastener 40 is configured to removably couple the cord to a first object, such as a helmet 80. In one illustrative embodiment, the helmet 80 has a slot 82 and the fastener 40 is configured to attach to the helmet slot 82.
The attachment system 200 also includes a tensioner 60 coupled to the cord 10. As set forth in more detail below, the tensioner 60 is configured to grip or hold a portion of the cord to maintain the tension in the cord 10. In one illustrative embodiment, the tensioner 60 has at least one tooth 64, 66 configured to grip a portion of the cord to maintain the tension in the cord. However, as set forth below, non-toothed tensioners 60 are also contemplated. As shown in FIGS. 1A-1B, the cord 10 may be coupled to a second object, such as a helmet accessory 84. As illustrated, the cord 10 is secured to one or more rings 86, 88 on the helmet accessory 84. FIG. 1A illustrates the helmet accessory 84 as a camera that is in a stowed position above the helmet, whereas FIG. 1B illustrates the camera in an “in use” position rotated down below the helmet 80.
In one illustrative embodiment, the fastener 40 is coupled to a first end 12 of the cord 10 and the tensioner 60 is coupled to a second end 14 of the cord. However, it is also contemplated that the fastener 40 and/or tensioner 60 are coupled to other portions of the cord, such as locations spaced apart from the first and second ends 12, 14, as the invention is not necessarily so limited. For example, it is contemplated that a portion of the cord may be folded over onto itself and the fastener 40 could be coupled to the folded portion of the cord.
As discussed in more detail below, and as shown in FIGS. 4-7, in one illustrative embodiment, the tensioner 60 has an opening 62. A portion of the cord 10 is passed through the opening 62 and the cord 10 is slid through the opening 62 until a desired cord tension is reached. Once the desired cord tension is reached, the tensioner 60 grips the cord 10 to prevent the cord 10 from moving relative to the tensioner 60, thus maintaining the tension in the cord. As set forth below, it should be appreciated that the present invention also contemplates embodiments where the tensioner 60 does not have an opening 62, as the invention is not necessarily limited in this respect.
In the illustrative embodiment in FIGS. 1A-1B, the attachment system 200 is configured to couple a helmet accessory 84 to a helmet 80. As set forth in greater detail below, it is also contemplated that the attachment system 200 may be configured to couple other objects together, as the invention is not necessarily limited in this respect.
Now turning to FIGS. 2-3, the fastener 40 is illustrated in greater detail. As previously mentioned, the fastener 40 is configured to be coupled to the cord 10, and the fastener 40 is configured to removably couple the cord 10 to a first object, such as a helmet 80. In one illustrative embodiment, the fastener 40 is a hook 42 configured to engage with a portion of the first object. For example, as shown in FIGS. 1A-1B, the fastener 40 engages the slot 82 on the helmet 80. As shown in FIGS. 2-3, the fastener 40 may include a substantially C-shaped hook 42. In one embodiment, the hook 42 is non-movable. In another embodiment, one or more portions of the hook 42 may move, and may for example, pivot between an open position and a closed position. Although the drawings illustrate the fastener 40 as a hook 42, other fastener arrangements are also contemplated.
FIGS. 4-7 illustrate the tensioner 60 in greater detail. In this illustrative embodiment, there is a toothed tensioner. As previously mentioned, the tensioner 60 is configured to be coupled to the cord, and the tensioner 60 may include one or more teeth 64, 66 configured to retain a portion of the cord 10 to maintain the tension in the cord 10. In the embodiment illustrated in FIGS. 4-7, the tensioner has a plurality of teeth 64, 66. However, other embodiments contemplate a single tooth, or non-toothed tensioner arrangements, as the invention is not necessarily limited in this respect.
As mentioned above, the tensioner 60 may include an opening 62 extending therethrough, and as shown in FIGS. 1A-1B, the cord 10 may pass through the opening 62. The opening 62 is configured to receive the cord 10 such that the one or more teeth 64, 66 can grip a portion of the cord to maintain the tension in the cord. The tension in the cord 10 may be adjusted by varying the position of the cord 10 relative to the tensioner 60. For example, pulling on the cord in one direction will increase the tension in the cord 10. Sliding the cord 10 in the opposite direction will decrease the tension in the cord 10. Alternatively, the tensioner 60 may be displaced relative to the cord 10.
As illustrated in FIGS. 6-7, the tensioner 60 may include at least one tooth 64 positioned on a first side 70 of the tensioner 60 and at least one tooth 66 positioned on a second side 72 of the tensioner 60. In one illustrative embodiment, the second side 72 of the tensioner 60 is opposite the first side 70 of the tensioner. Applicant recognized that placing teeth on each side 70, 72 of the tensioner enables the teeth to adequately grip the cord, regardless of the orientation of the tensioner 60. Furthermore, by placing the teeth on each side of the tensioner 60, at least one tooth 64 is offset from at least one tooth 66. With such a configuration, the cord 10 is gripped by a plurality of teeth 64, 66 that are spaced apart along the length of the cord 10. It is contemplated that such a configuration further enables the tensioner 60 to grip the cord 10, and thus retain the tension in the cord 10.
In one embodiment, the tensioner 60 has a first plurality of teeth 64 positioned on a top portion of the opening 62, and a second plurality of teeth 66 positioned on a bottom portion of the opening 62, where the top portion of the opening 62 is farther away from the first end 14 of the cord 10 than the bottom portion of the opening 62. Applicant recognized that placing teeth on both the top and bottom portions of the opening 62 enables the teeth to grip two opposing surfaces of the cord. In one particular embodiment, the tensioner 60 includes three upper teeth 64 and three lower teeth 66 and each of the teeth are configured to grip the cord 10 to maintain the tension in the cord. It is also contemplated that in one embodiment, there are more than three upper and lower teeth, and in another embodiment, there may be less than three upper and lower teeth. Further, a different number of teeth may be provided respectively on the top and bottom portions.
The tensioner 60 may be shaped to facilitate the positioning of the cord 10 relative to the teeth 64, 66. For example, in one embodiment, one or more surfaces of the tensioner are curved to facilitate the sliding movement of the cord when adjusting the tension in the cord. In one illustrative embodiment, the tensioner has a first concave surface 74 on a first side 70 of the tensioner 60 adjacent the opening 62. The tensioner 60 may also have a second concave surface 76 on the second side 72 of the tensioner 60 adjacent the opening 62.
As mentioned above, it is also contemplated that the tensioner 60 may be configured without an opening 62. For example, the tensioner 60 may include one or more gripping elements, such as teeth 64, 66 positioned on an outer surface of the tensioner 60 and the gripping elements may be configured to grip the cord 10 to maintain the cord tension.
As mentioned above, non-toothed tensioners are also contemplated. For example, the tensioner 60 may include a clamp configured to press against the cord, thereby maintaining the tension in the cord. The clamp may receive a portion of the cord and the clamp may be spring-loaded to press against the cord.
One of ordinary skill in the art would recognize that the tensioner 60 and/or the fastener 40 may be coupled to the cord using a variety of known techniques, such as, but not limited to adhesives, mechanical fasteners, and knotting the cord around the tensioner or fastener.
Applicant recognized that it may be difficult to connect and/or disconnect portions of the attachment system to a cord using known techniques. Thus, Applicant developed an attachment system with a fitting 20 that is configured to be easily connected and/or disconnected to the cord. This fitting 20 is configured to couple working components, such as a fastener 40 and/or tensioner 60, to the cord. In one embodiment, the fitting is configured to removably couple the tensioner 60 and/or the fastener 40 to the cord 10. As set forth below, the fitting 20 is configured to receive a portion of the cord, such as one end 12, 14 the cord, and portions of the fitting 20 press against the cord to retain the cord in the fitting 20. The fitting 20 is configured to interact with a working component, such as a tensioner 60 or fastener 40 to couple the working component to the fitting 20.
In the embodiment illustrated in FIGS. 2-5 and 8, a fitting 20 is configured to couple the tensioner 60 and/or the fastener 40 to the cord 10. There may be a first fitting configured to couple the tensioner 60 to the cord 10, and a second fitting configured to couple the fastener 40 to the cord 10. As set forth below, in one embodiment, the fitting 20 enables the cord to be easily connected to the tensioner 60 and/or the fastener 40. In this respect, the cord may pass through the opening 62 in the tensioner, and the cord may also be secured to an object, such as by passing the cord through the rings 86, 88 on the helmet accessory 84. Thereafter, the fitting 20 may be coupled to the cord 10, the fitting 20 may be secured to either the fastener or the tensioner, and the position of the cord relative to the tensioner may be adjusted to vary the tension in the cord. The tensioner 60 and/or fastener 40 may be sized such that once secured to the cord, the cord cannot easily be passed through the opening 62 in the tensioner. Thus, the fitting 20 easily allows the components to be connected after the cord is passed through the tensioner opening 62.
In one illustrative embodiment, the tensioner 60 and/or fastener 40 has a cavity 100 constructed to receive at least a portion of the fitting 20. As illustrated, the fitting 20 has an actively moveable element 22, 24 configured to retain the cord when the fitting 20 is positioned in the cavity 100. In one embodiment, the actively moveable element 22, 24 is configured as at least one arm, and in the illustrated embodiment it is configured as a plurality of arms. It is also contemplated that the moveable element 22, 24, may be shaped and configured differently, such as, but not limited to ring-shaped.
The fitting 20 may have a hole 34 extending axially therethrough, and the hole 34 may be configured to receive a portion of the cord. In one illustrative embodiment, the hole 34 is configured to receive an end 12, 14 of the cord 10. In another embodiment, it is also contemplated that the hole 34 is configured to receive another portion of the cord, and may, for example, be sized to receive a middle portion of the cord. As shown in FIG. 8, inserting a portion of the fitting 20 into the cavity 100 causes the actively moveable element 22, 24 to rotate inwardly and press against the cord, thus preventing movement of the cord 10 relative to the fitting 20. The inside of the cavity 100 may have a plurality of channels 102, 104 that align with the moveable element 22, 24. The channels 102, 104 may act as a track to guide movement of the fitting 20 into the cavity 100. The fitting 20 may interlock with the tensioner 60 and/or fastener 40 to couple the components together.
In one illustrative embodiment, the fitting 20 includes a first arm and a second arm, where the second arm is positioned opposite the first arm. Additional arms may also be provided. As mentioned above, other configurations for the actively moveable element 22, 24 are also contemplated.
In one embodiment, each of the arms of the actively moveable element 22, 24 include an inwardly facing projection 26, 28 configured to engage the cord when the fitting 20 is positioned in the cavity 100. The projection 26, 28 may have a pointed tip to grip the cord 10. In one illustrative embodiment, the plurality of arms may also include an outwardly facing detent 30, 32 configured to engage the tensioner 60 and/or fastener 40 when the fitting 20 is positioned in the cavity 100. For example, the outwardly facing detent 30, 32 may be configured to engage a recess 106 in the tensioner 60 and/or fastener 40 to provide an interference fit between the fitting 20 and the cavity 100. In another embodiment, there may be a snap-fit engagement between the two components. As illustrated in FIG. 8, the fitting 20 may include one or more openings 36 to enable the inwardly facing projections 26, 28 to directly contact the cord 10 when the cord 10 has been inserted into the hole 34 in the fitting 20.
In one embodiment, the fitting 20 is designed such that the components may not be easily decoupled once the components are assembled together. This may prevent the attachment system from undesirably disengaging with either of the first or second objects. For example, there may be an interference fit between the fitting 20 and the cavity 100 and a pin-like device may be required to press the moveable element 22, 24 inwardly to disengage the fitting 20 from the working component.
The drawings illustrate a fitting 20 configured to couple the tensioner 60 and/or the fastener 40 to the cord 10. It should also be appreciated that the fitting 20 may also be configured to couple other working components to a cord, as the invention is not necessarily so limited.
