The present invention is in the field of lanyards. More specifically, the present invention relates generally to systems, methods, and apparatus for coupling items to lanyards.
A lanyard is a cord, strap, line or other such member used to hold or fasten to an object. Lanyards are commonly worn by persons to secure items around their neck or body. One end of the lanyard typically includes a connector and/or clip to which the items can be attached, such as name tags, wallets, keys, lip balm, or any other personal item. A variety of different lanyards and lanyard connectors are presently available within the art.
A number of presently available lanyards and lanyard connectors utilize multiple separate component parts that are assembled together through many steps, some of which are difficult to perform and can result in assembler fatigue. This results in an increase in manufacturing time and the likelihood of error or manufacturing difficulties. Furthermore, using multiple separate components parts results in a more unwieldy or cumbersome lanyard or lanyard system. As such, there are a number of disadvantages in the art that can be addressed.
Implementations of the present invention solve one or more problems in the art with systems, methods, and apparatus for coupling items to lanyards. In particular, the present invention relates to a lanyard system having a lanyard coupler that receives a lanyard at one end and is selectively attachable or mountable to an attachment member on the other end. A lanyard coupler can include a body having a first end and a second end, an arm portion being formed toward the first end, with the body tapering from the first end toward the second end. A strap receiving opening extends across a portion of the body, while a connector extending from the second end of the body. Optionally, the arm portion can have a generally gooseneck shape with a hook portion.
In another configuration, the lanyard system includes a coupler having a body with an elongate slit extending across at least part of the body near a proximal end, the slit forming a proximal arm portion extending across the body proximal to the elongate slit. A connector extends away from the distal end of the body. The lanyard strap received within the slit has a weld that secures at least three layers of the lanyard strap together, thus forming a loop at a distal end of the lanyard strap.
In still another configuration, the lanyard system can be formed through an assembly method that includes providing a coupler and providing a lanyard strap. The coupler includes a lanyard strap receiving opening extending across a body near a proximal end of the body, the lanyard strap receiving opening forming an arm portion at the first end of the body. The lanyard strap has a loop formed by overlapping portions of the strap substrate and then forming a weld or welding the overlapping portions together, such as through a thermal or ultrasonic welding process. With the provided coupler and strap, the method includes attaching the lanyard strap to the coupler by inserting the lanyard strap into the lanyard strap receiving opening so that the lanyard strap passes through the lanyard strap receiving opening and the arm extends through the loop.
In another configuration, the arm portion of the coupler is connected to a body portion at a first side of the body and separated at a second side of the body. In so doing, the arm portion can extend in a cantilever fashion from a remainder of the body and form the lanyard strap receiving opening. Optionally, repeated protrusions or a roughened surface can be formed along all or a portion of the walls forming the lanyard strap receiving opening and so can surround the lanyard strap receiving opening.
In another configuration, a perimeter of the coupler includes a chamfer or tapered edge. The chamfer or tapered edge can extend along an entire length of the perimeter or along only a discrete portion of the perimeter, such as along all or a portion of the lanyard receiving opening, along all or a portion of the outer surface of the body, or some other combination.
In another configuration, the lanyard strap receiving opening can include a first opening portion and a second opening portion, the first opening portion having a first terminal end having a generally curved profile and a second terminal end terminating toward the second opening portion. The second opening portion can extend angularly from the first opening portion. Optionally, the second opening portion can have a first portion and a second portion, the first portion and the second portion being inclined relative to a longitudinal axis of the body at different inclinations. In another configuration, the first portion can extend from the first opening portion and the second portion extends from the first portion, the first portion being generally parallel to the longitudinal axis and the second portion being transverse to the longitudinal axis.
In still another configuration, the first portion and the second portion of the second opening portion can include at least one lip or protrusion, such as adjacent a junction of a first portion and a second portion forming the lanyard receiving opening. The at least one lip can form a narrow portion to the passageway of the second opening portion.
Additional features and advantages of exemplary implementations of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by the practice of such exemplary implementations. The features and advantages of such implementations may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims. These and other features will become more fully apparent from the following description and appended claims or may be learned by the practice of such exemplary implementations as set forth hereinafter.

Referring now to the
The strap 10 extends from the coupler 12 and receives a portion of the coupler 12 within a loop 22 at the distal end 16 of the strap 10 so that at least a portion of the strap 10 overlaps a portion of the coupler 12 when it is received within the loop 22. The loop 22 is formed by overlapping portions or layers of the strap 10, with three layers of strap 10 being joined together in the configuration illustrated in
In the illustrated embodiment of
Returning to
With continued reference to
The reinforcement portion 68, as illustrated in
Returning to
The connector 54 has two spaced apart members 56a, 56b that collectively form the connector 54 to which the attachment member 14 can be selectively coupled and about which the attachment member 14 can selectively rotate. The members 56a, 56b flex inwardly when being mounted to a base 70 of the attachment member 14, then flex outwardly to maintain (e.g., temporarily) the members 56a, 56b within the base 70. It is possible to detach the attachment member 14 from the coupler 12 upon applying sufficient force to move the parts apart e.g., by bending or otherwise manipulating the coupler 12 with respect to the attachment member 14 and pulling the parts apart.
Each member 56a, 56b includes a narrow portion 58a, 58b and an enlarged portion 60a, 60b. The narrow portion 58a, 58b has a generally semicircular cross-section, while the enlarged portion 60a, 60b tapers from the narrow portion 58a, 58b toward an end 62 of the connector 54. The generally semicircular cross-section allows rotational movement of the attachment member 14 relative to the coupler 12, aiding with comfortable positioning of the coupler 12 and an item supported by the attachment member 14 for the user.
With reference to
Slot 74a, 74b are formed in the base 70 thereby forming locking rim 76a, 76b to which the enlarged portions 60a, 60b contact as they flex outwardly. A portion of each enlarged portion 60a, 60b enters a respective one of the slots 74a, 74b so that a proximally facing portion of the enlarged portions 60a, 60b overlap with and engage with the locking rims 76a, 76b to prevent inadvertent detachment of the attachment member 14 from the connector 54 of the coupler 12. However, as mentioned above, it is possible to detach the attachment member 14 from the coupler 12 upon applying sufficient force to move the parts apart e.g., by bending or otherwise manipulating the coupler 12 with respect to the attachment member 14 and pulling the parts apart, causing the members 60a, 60b to move off the locking rims 76a, 76b and out of the base 70.
Turning to
The strap receiving opening 46 includes a first opening portion 90 and a second opening portion 92. The first opening portion 90 has a first terminal end 94 and a second terminal end 96 terminating toward the second opening portion 92. The first opening portion 90 extends horizontally at least partially across a body 40 of the coupler 12 at or near the first proximal end 42 of the coupler 12. In the illustrated configuration, each of the first terminal end 94 and the second terminal end 96 have a curved profile to accommodate the edges of the strap 10. For instance, to aid with retaining in the strap 10 within the strap receiving opening 46, an edge 32 of the strap 10 fits within the curved profile to provide a tight fit and limit lateral movement of the strap 10 relative to the coupler 12. While the curved profile can approximate the size and dimension of the strap 10 and edge 32, it will be understood by one skilled in the art that in other configurations the curved profile need not approximate the strap 10 and edge 32.
Extending from the first opening portion 90 is the second opening portion 92, as illustrated in
As illustrated, the second opening portion 92 includes a first portion 100 and a second portion 102 that is slanted relative to the first portion 100. The first portion 100 can also be inclined relative to the first opening portion 90 or can be perpendicular to the first opening portion 90. Stated another way, the combination of the first portion 100 and the second portion 102 forms an angled passageway that extends from the first opening portion 92 in a proximal-to-distal direction, i.e., downwardly. Alternatively, the combination of the first portion 100 and the second portion 102 forms an angled passageway that extends from the first opening portion 92 in a distal-to-proximal direction, i.e., upwardly. In either case, the first portion 100 can be transverse to the first opening portion 90 (such as transverse to an axis extending in the proximal-to-distal direction, such as a longitudinal axis) or perpendicular to the first opening portion 90 (such as parallel to the axis extending in the proximal-to-distal direction, such as the longitudinal axis) and the second portion 102 can be transverse or perpendicular to the first portion 100, which results in the second portion being transverse to or perpendicular to the axis extending in the proximal-to-distal direction, such as a longitudinal axis.
To form the first portion 100 and the second portion 102, the arm portion 50 includes a wall 110 extending from the second terminal end 96 and a wall 112 that is slanted relative to the first wall 110. The junction of the wall 110 and wall 112 forming a lip 118 that provides resistance to a movement of the strap 10 out of the strap receiving opening 14. Similarly, the body portion 52 includes a wall 114 extending from the first opening portion 90 and a wall 116 that is slanted relative to the wall 114. The walls 110, 114 define a perimeter of the first portion 100 of the second opening portion 92, while the walls 112, 116 define a perimeter of the second portion 100 of the second opening portion 92.
The embodiment of
A lip 124′ is formed across the second opening portion 92′ from the lip 118′. The combination of the lip 118′ and the lip 124′ collectively narrows the second opening portion 92′ close to the first opening portion 90 to prevent the strap 10 becoming inadvertently detached from the coupler 12′. It will be understood, that in other embodiments, the coupler can include only the lip 118′ or only the lip 124′, rather than both lips. The second opening portion 92′ can be narrowed by about 35 percent to about 40 percent as compared to the end of the second opening portion 92′ at the perimeter 98′ of the body 40′ by the lip 118′, the lip 124′, or a combination of the lip 118′ and the lip 124′. Alternatively, the second opening portion 92′ can be narrowed by about 10 percent to about 90 percent, by about 20 percent to about 80 percent, by about 30 percent to about 70 percent, by about 65 percent to about 90 percent, by about 20 percent to about 35 percent, by about 40 percent to about 65 percent, or by about 10 percent to about 20 percent.
While the embodiments illustrated in
Additionally, while reference is made to the lip 118′ and the lip 124′ being opposite to each other across the second opening portion 92′, the lip 118′ and the lip 124′ can be offset from each other along the second opening portion 92′. This results in the second opening portion 92′ has a serpentine, bending, tortuous, or twisting form. For instance, with the lip 118′ near the first opening portion 90′ the lip 124′ is closer to the perimeter 98′ than the lip 118′ to form the serpentine, bending, tortuous, or twisting second opening portion 92′. Similarly, with the lip 124′ near the first opening portion 90′ the lip 118′ is closer to the perimeter 98′ than the lip 124′ to form the serpentine, bending, tortuous, or twisting second opening portion 92′.
In addition to the couplers 12, 12′ described and shown herein, one or more embodiments of a coupler 12 can also include one or more protrusions 120 within the strap receiving opening 46, including one or both of the first opening portion 90 and the second opening portion 92. For example, a plurality of repeated protrusions 120, or “teeth,” can be formed along the inside edge or edges of the strap receiving opening 46. The protrusions increase the surface area and frictional contact between the strap 10 and the inside edge or edges of the strap receiving opening 46 to form a more secure connection therebetween. The protrusions can be any number or combination of shapes, including triangular or semicircular protrusions that run along the inside edge or edges of the strap receiving opening 46. Alternatively, all or portions of the strap receiving opening 46, and more generally the body 40, can be roughened or textured to change the frictional engagement between the coupler 12 and the strap 10. Stated another way, all or portions of the strap receiving opening 46, and more generally the body 40, can receive a surface finish to provide desired frictional engagement between the coupler 12 and the strap 10 and/or the coupler 12 and the attachment member 14. For instance, a surface finish to aid with rotational movement of the attachment member 14 about the connector 54 can be applied to one or both of the attachment member 14 and the connector 54, such as applying a TEFLON coating or other low friction coatings. Alternatively, to prevent unwanted movement between the strap 10 and the coupler 12, an appropriate surface finish, such as the protrusions 120 or other roughening surface technique, can be applied to limit movement of the strap 10 within the strap receipting opening 46.
As mentioned above, each of the couplers can either directly or indirectly connect to the attachment member. For an indirect connection, the intermediate adapter 130 can be used. As illustrated in
To manufacture the lanyard system, the strap 10 is welded to form the loop 22 prior to coupling the strap 10 and coupler 12 together. In another embodiment, the strap 10 is first threaded through the strap receiving opening 46 and then the loop 22 is formed by welding the together the first end portion 24, the second end portion 26, and the intermediate portion 28 of the strap 10 together. Additionally, or alternatively, the joint region 30 is provided closer to the proximal arm 20 of the coupler 12 so that the loop is tightly formed around the arm portion 50. In such an embodiment, the loop 22 of the strap 10 may be too small to be moved through the second opening portion 82 and from the coupler 12, thus securing the strap 10 to the coupler 12.
For example, in one embodiment, the strap 10 is welded to form the loop 22 of a first size. The arm portion 20 is then inserted through the loop 22, and then a second weld 30′ (
Generally, the strap, coupler, and the attachment member can each have a variety of sizes and shapes according to various implementations of the present disclosure.
