The present invention relates generally to equipment for individuals who sometimes work at heights, such as construction workers, tower technicians, military and police, firefighters and other rescue professionals.
In some instances, firefighters use safety equipment such as harnesses. In some cases, there is a desire for convenient, easy-to-use harnesses that are comfortable to carry or wear yet can easily be deployed.
An embodiment of the invention is a multi-part bag system designed to hold a firefighter's bailout gear.
A carry and deploy bag system according to embodiments of the present invention includes a holster for housing a controlled descent device and an anchor; a rope pouch for receiving a rope that is securable to the controlled descent device and the anchor; and a connecting gooseneck extending between the holster and the lumbar pouch that protects the rope as it runs through the connecting gooseneck from the lumbar pouch to the holster; wherein the holster comprises a tear-away cover flap that can be opened and disconnected from the holster in one motion.
Another carry and deploy bag system according to embodiments of the present invention includes a holster for housing a controlled descent device and an anchor; a rope pouch for receiving a rope that is securable to the controlled descent device and the anchor; and a connecting gooseneck extending between the holster and the lumbar pouch that protects the rope as it runs through the connecting gooseneck from the lumbar pouch to the holster; wherein the holster comprises an anchor hook holding mechanism configured to hold the anchor hook at an angle with respect to vertical.
While multiple embodiments are disclosed, still other embodiments of the present invention will become apparent to those skilled in the art from the following detailed description, which shows and describes illustrative embodiments of the invention. Accordingly, the drawings and detailed description are to be regarded as illustrative in nature and not restrictive.
While the invention is amenable to various modifications and alternative forms, specific embodiments have been shown by way of example in the drawings and are described in detail below. The intention, however, is not to limit the invention to the particular embodiments described. On the contrary, the invention is intended to cover all modifications, equivalents, and alternatives falling within the scope of the invention as defined by the appended claims.
A system according to embodiments of the present invention may include one or more of the following characteristics and/or features:
Embodiments of the present invention may by used by firefighters, though some embodiments of the invention may be useful to those who wear gloves or mittens that reduce dexterity. Ribs 702 on one or both sides of the flap make it easy to grab with heavy wet gloves.
Embodiments of the present invention may provide certain benefits in the context of firefighting, according to embodiments of the present invention. However, anyone who carries a personal vertical escape and rescue system may find similar benefits.
The multi-part bag system 100 according to embodiments of the present invention can be field stripped and completely disassembled, mid-descent if necessary, to clear any sort of rope jam. The multi-part design also makes it easy to use connecting pieces—for example the rope conduit gooseneck—of different length to accommodate firefighters of different girth, according to embodiments of the present invention. Three such goosenecks 106, 108, 110 are shown in
According to some embodiments of the present invention, the bag system 100 has rope-contacting parts that contact rope which are made of a low-friction material such as Teflon fabric. This low-friction material facilitates rope deployment. Without it, increased friction in the gooseneck may in some cases cause the rope to get stuck. A low-friction material in the rope bag 102, for example, allows rope that is “stuffed” to deploy smoothly without twists or kinks because it allows rope to untwist as it is pulled from the bag.
The holster 104 according to embodiments of the present invention has a tear-away cover flap 302 that can be opened and disconnected in one motion. This makes it faster and easier for a firefighter to access bailout equipment, according to embodiments of the present invention.
The holster 104 according to embodiments of the present invention includes retaining straps 304, 306 that connect to the under-side 308 of the cover flap 302. Retaining straps 304, 306 keep bailout equipment secure inside the holster 104 and prevent premature or accidental deployment of the gear. When these straps 304, 306 are fastened to the underside 308 of the cover flap 302, they are out of the way and less likely to snag as a firefighter goes about his work. Attaching these cover straps 304, 306 to the cover flap 302 in the manner indicated allows them to easily disengage when the cover flap is opened.
A holster 104 according to embodiments of the present invention may hold the anchor hook 310 at an angle. The most advantageous place to grasp an anchor hook 310 is by the portion of the anchor hook 310 that transitions from the curve to the straight shaft. Grasping too far onto the curve or too far onto the straight shaft makes it difficult to position the hook 310 so that it will drive into a wall. If the hook 310 is positioned in the holster 104 so that the straight shaft 312 is vertical, then the portion of the hook 310 that is most naturally grasped is the curved portion of the hook 310. If the hook 310 is positioned in the holster 104 so that the straight shaft 312 is horizontal, then the portion of the hook 310 that is most naturally grasped is the straight shaft 312. Positioning the hook 310 so that it is between ten and forty-five degrees from vertical (with vertical being a substantially up-down direction from the nominal orientation of
A holster 104 according to embodiments of the present invention secures the tip 314 of the anchor hook in a bottomless pocket 316. The tip 314 of a firefighter's anchor hook 310 is sharp and can easily tear the material of the bag that holds it. The bottomless-pocket 316 secures the tip 314 of the anchor hook 310 so that the tip 314 is not in contact with the holster bag 104 and the holster bag 104 is therefore not in jeopardy of being torn.
A holster 104 according to embodiments of the present invention includes a cover flap 302 that incorporates a multiplicity of waves or ridges 702. A firefighter's hands can be burned or frozen when a bailout emergency occurs. A holster flap 302 with a multiplicity of waves or ridges 702 makes it easier for numb fingers to find the appropriate part of the flap to pull. Also, the three-dimensional waves or ridges 702 reduce the compression necessary by fingers to prevent fingers from slipping against the material of the flap. And, the waves or ridges 702 provide tactile feedback to the user to indicate that fingers are slipping over the surface, which the user can then use to squeeze the flap more vigorously to prevent slipping.
As illustrated in
Bag system 100 may have parts which contact rope made of a low-friction material such as Teflon fabric. The coefficient of friction of ultra-high molecular weight polyethylene may also be suitable, though the melt temperature of UHMWP is less than ideal in some situations.
A holster 104 according to embodiments of the present invention may include a tear-away cover flap 302 that can be opened and disconnected in one motion. The cover flap 302 of this embodiment is folded over and attached on the “wrong side” to the top of the holster with Velcro as shown in
The holster 104 has retaining straps 304, 306 that connect to the under-side 308 of the cover flap 302, according to embodiments of the present invention. The retaining straps 304, 306 of this embodiment are sewn to the back side of the holster 104 and then wrap around the side of the holster that has the protruding carabiner, as illustrated in
As described above, the holster 104 may be configured to hold the anchor hook 310 at an angle. Some embodiments feature an anchor hook 310 angle of five to forty-five degrees from vertical with the tip 314 of the hook 310 angled downwardly, as illustrated in
The holster 104 may secures the tip 314 of the anchor hook 310 in a bottomless pocket 316, according to embodiments of the present invention. This “bottomless pocket” may be a pocket with a either no bottom or a bottom that is substantially deeper than it is possible for the tip 314 of the hook to penetrate into the pocket. An easy way to make a bottomless pocket is simply to attach a piece of webbing to the holster leaving an un-sewn gap (for example along the top edge) for the tip 314 of the hook 310.
The holster 104 may include a cover flap 302 that incorporates a multiplicity of waves or ridges 702. The portion of the cover flap 302 designed to be grasped to open the holster 104 can contain a single or plurality of parallel, concentric or random ridges or protrusions 702 that facilitate grasping and pulling or lifting of the flap 302. The ridges 702 can be on either or both sides of the flap 302, according to embodiments of the present invention. A “negative ridge” or “indent” functions the same as a “positive ridge” because the point is to create contrast for fingers and palm to feel, according to embodiments of the present invention. Ridge or protrusion effectiveness is determined by amplitude, wavelength and shape. Amplitude is defined as the difference between the base material and the height or depth of the ridge or protrusion. Wavelength is defined as the distance between amplitude crests or troughs. Shape is defined by the cross-section of the ridge or protrusion. A singular ridge or protrusion is less effective than a correctly designed plurality of ridges or protrusions 702. A ridge is most effective when it is substantially perpendicular to the user's fingers as the user grabs the flap. The effective amplitude for a ridge or protrusion is 0.25 mm to 13 mm in some embodiments, is 2 mm to 10 mm in other embodiments, and is 4 mm to 7 mm in other embodiments. Frequency is a function of amplitude. The effective frequency is 1× to 10× the amplitude in some embodiments, is 2× to 7× in some embodiments, and is 3× to 5× in some embodiments. One effective shape has a profile that has one or more acute angles. Another factor that affects the ability of a user to grab a flap is the flexibility of the part of the flap that is grasped. Stiffer is better when the size of the portion of the flap to be grasped is small relative to the size of the user's hand, according to embodiments of the present invention.
Specific ways to create these ridges 702 include, without limitation: (1) gathering and sewing small flaps of fabric to create ridges or protrusions on either or both sides of the flap, (2) sewing pieces of cord or rope into the flap so that the rope creates a ridge on either or both sides of the flap (the rope diameter used to create ridges can be as large as 12.5 mm or as small as 2 mm), and/or (3) attaching an extruded profile that has ridges or protrusions on either or both sides of the flap.
Various modifications and additions can be made to the exemplary embodiments discussed without departing from the scope of the present invention. For example, while the embodiments described above refer to particular features, the scope of this invention also includes embodiments having different combinations of features and embodiments that do not include all of the described features. Accordingly, the scope of the present invention is intended to embrace all such alternatives, modifications, and variations as fall within the scope of the claims, together with all equivalents thereof.
