BACKGROUND
The personal protective equipment (PPE) market has experienced a significant shift on the safety connection between the human body equipped with a safety harness and a secure anchor point. The traditional fixed length lanyards are being replaced by the use of self-retracting devices (SRDs). This market shift to SRDs has created several issues for the end users.
The relatively light weight fixed length lanyard is now being replaced by retractables, weighing significantly more, and is creating an industry wide safety issue for the end user in regards to the dorsal D-ring location. Due to the increased weight, the dorsal D-ring (the “D” shaped connector for SRDs) and any pad connected to it tends to slide down the user's back due to the weight of retractibles (often used in a set of two). This is creating a potentially catastrophic situation in both feet first and head first fall events due to movement of the SRD(s) connector point.
Typical installation of SRDs to the dorsal D-ring area is a time consuming process. Conventionally, the user needs to create a loop out of the torso webbing just below the dorsal D-ring then pass the SRD attachment point (often a safety rated carabiner) through this loop of webbing. This can be challenging for end users and can consume up to fifteen (15) minutes for installation and another fifteen (15) minutes for removal of the SRDs.

DETAILED DESCRIPTION
The descriptions of the various embodiments have been presented for purposes of illustration, but are not intended to be exhaustive or limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The terminology used herein was chosen to best explain the principles of the embodiments, the practical application or technical improvement over technologies found in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein.
Embodiments relate to integration of a pre-established SRD connection point into a dorsal ring (e.g., D-ring, oval ring, etc.) “keeper.” One embodiment includes an apparatus that includes a ring connection element having an opening configured to removably connect with a ring device (e.g., a D-ring, oval ring, etc.) and an SRD attachment port integrated with the ring connection element. One embodiment connects to or is integrated with a base plate that includes one or more integrated tension clips to secure the SRD connection point and to prevent the entire assembly from re-positioning.
Some conventional connection points are not fixed to a D-ring plate, which makes it hard for a user to attach this component and difficult for the component to remain in the correct location. Many conventional devices also fail to address the added weight of SRDs and the inherent slippage caused by this added weight. Other conventional SRD attachment points consist of a metal part built into or off of the dorsal D-ring. This is a heavy and costly alternative and does not address the slippage caused by the weight of SRDs added to a safety harness.
FIG. 1 shows a side view of a device 100 including an integrated SRD connection point 120 and (dorsal) D-ring position keeper (or connection point) 110, according to an embodiment. The device 100 includes a base plate 130, SRD connection point (or SRD quick attachment port) 120 with outer portion 105 and D-ring position keeper 110. In one embodiment, the D-ring position keeper 110 includes an opening for placement of a D-ring device (e.g., D-ring 230, FIG. 2), or other ring type devices (e.g., an oval ring, circular ring, etc.). The D-ring position keeper 110 provides stability of a D-ring that is placed in the D-ring position keeper 110 along with webbing (e.g., webbing 210, FIG. 2) that is placed over an opening portion of a D-ring (or other ring device). In one embodiment, the SRD connection point 120 includes a though-hole or slot for placement of an SRD connector (e.g., round carabiners, oval carabiners, etc. either made of aluminum, steel, etc.).
FIG. 2 shows a top view of the device 100 including the integrated SRD connection point 120 and (dorsal) D-ring position keeper 110 of FIG. 1, according to an embodiment. In one embodiment, the device 100 further includes webbing slots 225 and integrated tension clips 226 for webbing 210 (e.g., webbing from a safety harness). The webbing slots 225 provide a functional means to incorporate the torso webbing from a safety harness through the base plate 130 or the D-ring keeper 110 with an SRD adaptor assembly. Without this feature the critical dorsal D-ring placement would be lost and the safety of the user would be jeopardized.
In one embodiment, the base plate 130 is the foundation of the device 100 providing the surface in which to build all the other components on. The base plate 130 may be made in a variety of shapes and sizes, ranging from a simple flat shape to a complex multifaceted, multi-contoured shape. The base plate 130 may be sewn in place on padding, riveted, epoxy welded, etc. In one embodiment, the materials for the base plate 130 may range from steel, a steel alloy, an aluminum alloy, plastic resins, leather, fabric, etc.
In one embodiment, the D-ring keeper 110 is a feature that allows a (dorsal) D-ring 230 to maintain a safe and fixed distance from the SRD connection point 120. If the D-ring keeper 110 and the SRD connection point 120 are not within reasonable proximity of each other, the device 100 function can be jeopardized by becoming lost once the safety harness webbing 210 has been laced through the base plate 130 via the webbing slots 225 and integrated tension clips 226. The D-ring keeper 110 may also be strategically contoured or shaped to suit the intended D-ring 230 creating a stand-up or upright D-ring position, which makes it easier for the user to connect/disconnected lanyards and SRDs that are allowed to be connected directly to a dorsal D-ring. In one embodiment, the D-ring 230 is held in place by in a specific location. SRDs have a specific allowable usage marked on every unit. For example, the device can be used only for . . . overhead, 2′ below D-ring, 3′ below D-ring, 4′ below D-ring or foot level tie-off, etc. These are very specific instructions on personal SRDs. Therefore, if the SRD connection point 120 is too far away from the D-ring 230 one can end up with a miscalculation on the clear fall distance, which is the amount of distance one needs to calculate for a fall to prevent the user from hitting the lower level (or ground).
In one embodiment, the SRD connection point 120 creates a fixed loop on the base plate 130 allowing the torso webbing (e.g., webbing 210) from a safety harness to go over the top portion 105 and around the SRD connection point 120 to create a fast and safe connection for SRD attachment devices. The SRD connection point 120 may either be formed directly into the base plate 130 or permanently affixed to the base plate 130 through other means, such as riveting, cementing, a formed connection point method, etc. In one embodiment, materials used for the SRD connection point 120 may range from metal, metal alloy (e.g., steel alloy, aluminum alloy, etc.), plastic resins, leather, fabric, etc. The SRD connection point 120 may be made in the same material as the base plate 130, or alternative materials or an alternative material property (i.e., harder or softer).

In one embodiment, the integrated SRD connection point 820 and the D-ring position keeper 810 may be formed separately from the base plate 830 and attached to the base plate 830 via attachment means, such as welding, fasteners, etc. In another embodiment, the integrated SRD connection point 820 and the D-ring position keeper 810 may be formed together with the base plate 830 (e.g., molded together). The device 800 may be connected to the webbing (e.g., webbing 210, FIGS. 2 and 4) through the webbing slots 825.
FIG. 9 shows a top view of an example 900 including the integrated SRD connection point 820 and dorsal D-ring position keeper 810 (not shown in FIG. 9 due to webbing 210) of FIG. 8 shown with an exemplary D-ring 230 and harness 910, according to an embodiment. As shown, the webbing 210 is placed through the webbing slots 825 of the base plate 830 and over the outer portion 805 (not shown as the webbing 210 covers the outer portion 805), through the opening in the lower portion of the D-ring 230 and back through further webbing slots 825.
FIG. 10 shows a perspective view of the device 900 of the integrated SRD connection point 820 and dorsal D-ring position keeper 810 of FIG. 9 shown with the exemplary D-ring 230 and harness 910, according to an embodiment.
In one or more embodiments, the outer shape of the devices incorporating a D-ring keeper and SRD connection point (e.g., device 100, FIGS. 1-2, 300, FIGS. 3-4, 500, FIGS. 5-6, 700, FIG. 7, and 800, FIG. 8) along with the inner shape are strategically designed to serve specific purposes. In one example embodiment, the outer shape particularly the narrow top surface and sculpted curved sides along with the inner shape (e.g., oval in a vertical direction being taller than the horizontal direction) are all designed to accommodate common SRD connection options, such as oval carabiners, conventional shaped aluminum carabiners, steel carabiners, etc. that are common to the fall protection market. Without the shape designed in the above-discussed embodiments, the devices would be limited regarding the SRD connection options. In some embodiments, the top outer surface of the device is narrow and the device has sculpted curved sides along with an oval shape in a vertical direction being taller than the horizontal direction. This shape could also be made in the opposite direction with the sides narrow and the oval in a horizontal direction. In some embodiments, whatever direction the oval is taller or longer in, the outer shape has to be narrower in that same direction. In other embodiments, the shape of the through-hole or opening in the SRD connection point may be circular, oval, multi-faceted (e.g., pentagonal, octagonal, etc.), etc.
FIG. 11 shows an integrated webbing tension clip 1126 for webbing slots 1125, according to an embodiment. In one embodiment, the function of the integrated tension clip 1126 is to secure the (dorsal) D-ring keeper (e.g., D-ring keeper 110, FIGS. 1-2, 310, FIGS. 3-4, 510, FIGS. 5-6, 710, FIG. 7, and 810, FIG. 8) in the properly specified location. While webbing slots (e.g., webbing slot 1125) help to hold the (dorsal) D-ring keeper to a safety harness by lacing the webbing through them, these fail to adequately secure the location of the (dorsal) D-ring keeper. In one embodiment, the integrated tension clip 1126 includes multiple raised gripping elements (e.g., 2 or more) on the top portion of the integrated tension clip 1126, which are designed to cause additional friction with webbing and prevent slipping of the webbing when inserted into the webbing slots 1125.

In one embodiment, the webbing transition openings 1320, 1321, 1322 and 1323 each include smooth openings without any sharp edges (e.g., rounded edges, etc.), even at the point (or portion) near or at the formed V portion. The webbing transition openings 1320, 1321, 1322 and 1323 have an equal length on either side of the point or portion (upper and lower points/portions of the opening) near or at the formed V-shaped portions. In one embodiment, the width of the openings for the webbing transition openings 1320, 1321, 1322 and 1323, and the first webbing entry opening (or slot) 1315 and the second webbing entry opening (or slot) 1316 are 3 mm. In other embodiments, the width of the openings for the webbing transition openings 1320, 1321, 1322 and 1323, and the first webbing entry opening (or slot) 1315 and the second webbing entry opening (or slot) 1316 have a range of 2 mm-4 mm.
In one embodiment, the first D-ring attachment opening (or slot) 1330 and the second D-ring attachment opening (or slot) 1335 each include smooth openings without any sharp edges (e.g., rounded edges, etc.). In one embodiment, the openings of the first D-ring attachment opening (or slot) 1330 and the second D-ring attachment opening (or slot) 1335 have a width of 6.5 mm. In other embodiments, the openings of the first D-ring attachment opening (or slot) 1330 and the second D-ring attachment opening (or slot) 1335 have a width with a range of 4 mm-8 mm.
In one embodiment, the first webbing exit opening (or slot) 1326 and the second webbing exit opening (or slot) 1325 each include smooth openings without any sharp edges (e.g., rounded edges, etc.), even at the point (or portion) near or at the formed V portion. The first webbing exit opening (or slot) 1326 and the second webbing exit opening (or slot) 1325 have an unequal length on either side of the point (upper and lower points (1351/1352FIG. 13B) of the opening) near or at the formed V portion. In one embodiment, the length 1353 (or distance) between the lower formed V points 1351/1352 formed of each of the first webbing exit opening (or slot) 1326 and the second webbing exit opening (or slot) 1325 is 45 mm, which is the same as the length of the second D-ring attachment opening (or slot) 1335. The first webbing exit opening (or slot) 1326 and the second webbing exit opening (or slot) 1325 provide a functional means to incorporate the torso webbing from a safety harness through the base plate 1310 or the D-ring keeper 1340 with an SRD adaptor assembly. Without this feature the critical dorsal D-ring placement would be lost and the safety of the user would be jeopardized.
In one embodiment, the materials for the base plate 1310 may include high-density polyethylene (HDPE or HDPE plastic), thermoplastic elastomer (TPE), or a combination of the two. In other embodiments, the materials for the base plate 1310 may include steel, a steel alloy, an aluminum alloy, plastic resins, leather, fabric, etc. In one embodiment, the materials for the base plate 1310 are 70% HDPE and 30% TPE.

FIG. 13B shows a rear view of the device 1300 of FIG. 13A including the integrated SRD connection point and D-ring position keeper 1340, according to one embodiment. In one embodiment, the D-ring keeper 1340 is a feature that allows a (dorsal) D-ring 230 to maintain a safe and fixed distance from the SRD connection point. If the D-ring keeper 1340 and the SRD connection point are not within reasonable proximity of each other, the device 1300 function can be jeopardized by becoming “lost” once the safety harness webbings 1610/1620 (FIG. 16) have been laced through the base plate 1310 via the first webbing entry opening (or slot) 1315, the second webbing entry opening (or slot) 1316, the webbing transition openings 1320, 1321, 1322 and 1323, the first webbing exit opening (or slot) 1326 and the second webbing exit opening (or slot) 1325. The D-ring keeper 1340 may also be strategically contoured or shaped to suit the intended D-ring 230 creating a stand-up or upright D-ring position, which makes it easier for the user to connect/disconnected lanyards and SRDs that are provided to be connected directly to a dorsal D-ring.
In one embodiment, the D-ring 230 is held in place in a specific location. SRDs have a specific allowable usage marked on every unit. For example, an SRD can be used only for overhead, 2′ below D-ring, 3′ below D-ring, 4′ below D-ring or foot level tie-off, etc. These are very specific instructions on personal SRDs. Therefore, if the SRD connection point is too far away from the D-ring 230 one can end up with a miscalculation on the clear fall distance, which is the amount of distance one needs to calculate for a fall to prevent the user from hitting the lower level (or ground).
In some embodiments, the outer shape of the device 1300 incorporating a D-ring keeper 1340 and SRD connection point along with the inner shape are strategically designed to serve specific purposes. In one example embodiment, the outer shape is designed to accommodate common SRD connection options, such as oval carabiners, conventional shaped aluminum carabiners, steel carabiners, etc. that are common to the fall protection market. Without the shape designed in the above-discussed embodiments, the devices would be limited regarding the SRD connection options.

FIG. 15B shows a left side view of the device 1300 of FIG. 13A including the integrated SRD connection point and D-ring position keeper 1340, according to one embodiment.
FIG. 16 shows a front view of the device 1300 of FIG. 13A including the integrated SRD connection point and D-ring position keeper 1340 that is shown with example webbing 1610/1620 from a fall protection harness 1700 (FIG. 17), according to one embodiment. In some embodiments, the angle of the formed “V” of the webbing transition openings 1320, 1321, 1322 and 1323, the first webbing exit opening (or slot) 1326 and the second webbing exit opening (or slot) 1325 provide the proper alignment for the webbings 1610 and 1620 as they enter, exit and transition through the device 1300.
FIG. 17 shows a front view of the device 1300 of FIG. 13A including the integrated SRD connection point and D-ring position keeper 1340 that is shown with an example fall protection harness 1700, according to one embodiment. In some embodiments, the device 1300 may be included with a harness 1700, or may be added to a harness 1700 as required for fall protection that requires an SRD attachment and dorsal placed D-ring 230. The webbings 1610 and 1620 can be seen as “bending” through the device 1300 for proper alignment and exit angle of the webbings 1610 and 1620 from the device 1300. This provides for added comfort for the user, added safety features from a connection point for properly placing/positioning an SRD and for maintaining a D-ring 230 at a proper required location, position and angle for connection with a carabiner or other device.
