Apparatus and Method of Self-Rescue

CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY

[001] The present application claims priority from Indian patent application

202021046939.

TECHNICAL FIELD

[002] The present invention relates to an apparatus and method for self-rescue for a person buried under snow, ice or dirt.

BACKGROUND OF THE INVENTION

[003] An avalanche is a natural disaster linked to snow. Also referred to as snow slide in common parlance, an avalanche is an event that occurs when a cohesive slab of snow lying on a weaker section of snow fractures and slides down the mountain. Avalanches accelerate rapidly and grow in mass and volume as they gather more snow. Avalanches can be triggered by natural causes such as gravity and heavy snow fall or by earthquakes, excessive force from skiers, mountaineers, animals or by explosive devices.

[004] Skiers, mountaineers, hikers, snow boarders , army personnel and those living in mountainous regions are susceptible to avalanches. Avalanches can be dangerous with speeds approaching hundred of miles per hours. A human encountering such avalanche has little to no chance of outrunning the avalanche. Each year avalanches kill more than 150 people worldwide. 74 Indian Army personnel have died due to avalanches from 2017 to 2019. Most common causes are suffocation, hypothermia & wounds.

[005] If a person does manage to outlive the initial impact of the avalanche, being buried several feet under the snow is inevitable. If completely buried, a victim has a greater than 90% survival rate if they are found and extricated within about 15 minutes, but only a 30% survival rate if the rescue time stretches to 30 minutes.

[006] Rescue teams take time to reach the accident site and then proceed to find the trapped victim. Moreover all equipment available today in the market are either limited to the rescue operations team or they just create a small time span for the victim till the rescue team finds him/her.

[007] Rocks and debris sliding down a mountain behave similar to snow. A rockslide or mudslide is also referred to as an avalanche though snow avalanches are more predominant.

[008] Currently existing methods are usually ones used by search and rescue teams. It is uncommon for mountaineers to carry equipment as it tends to add to the weight of the paraphernalia carried by them on their backs which is undesirable.

[009] Avalanches often occur in the wild and unregulated environments.

Therefore the people who go to resorts are less likely to encounter an avalanche. Backcountry skiers/snowboarders, who explore the sport in the wild are more susceptible to avalanches.

[0010] Backcountry enthusiasts are always well trained and never are casual about the sport. In training, they are taught about avalanche safety and rescue. Hence, every athlete religiously carries important rescue equipment i.e transceivers/beacons, probes & shovels.

[0011] Existing methods used by search and rescue teams are: i. Avalanche cords: A long red cord (similar to parachute cord) is attached to the person's belt. While skiing, snowboarding, or walking the cord is dragged along behind the person. The assumption is that if the person gets buried in an avalanche, the light cord stays on top of the snow (it doesn’t always work). The use of avalanche cords goes back to over 100 years. ii. Beacons: Avalanche Transceiver or avalanche beacon is a type of emergency locator, a radio transceiver (a transmitter and receiver in one unit) serving the purpose of finding people buried under snow. iii. Probes: Portable (collapsible) probes are sticks that can be extended to probe into the snow to locate the victim. iv. Shovels: Shovels are used for digging through the snow to the victim. v. Avalung: The snow around the buried victims melts from the heat of the victim's breath and then refreezes stopping the flow of oxygen. The device consists of a mouth piece, a flap valve, an exhaust pipe, and an air collector which stores exhaled air. This buys additional time for rescuers to dig the victim out. vi. Avalanche airbags: Avalanche airbags help a person avoid burial by making the user a less dense object relative to the moving snow, which forces the person towards the surface.

[012] All equipment available today in the market are either limited to the rescue operations team or they just create a small time span for the victim till the rescue team finds him/her. No product available in the market provides the victim the ability to create their way out.

[013] What is lacking in the prior art is a light weight device that can be used by the user who might encounter an avalanche in the time span spent awaiting the rescue mission. Prior art lacks a lifesaving safety equipment that empowers the victim to rescue themselves out of an avalanche.

SUMMARY OF THE INVENTION

[014] The present disclosure relates to an apparatus and method for self-rescue. The present invention discloses a self rescue apparatus (100) wherein the self rescue apparatus (100) comprises of a body (101) and finger-like projections(102); wherein the finger like projections (102) possess saw-like serrations on the top surface called top teeth (103 a) and a front tip (103b) in the front wherein the lower side of the finger like projections have a curved hook (gripper) (104a) and serrated bottom teeth (104b); wherein the inner surface of the body (101) is affixed with a non-slip padding (105); and wherein the sides of the body (101) orthogonal to the finger like projections (103) has a handle (107) comprising of straps (106).

[0015] The present invention further discloses a method for self-rescue using the self-rescue apparatus wherein the self rescue apparatus is strapped onto the User’s (110) hand, the finger like projections (102) facing outwards, aligned in the direction of the fingers of the User(l lO); the User (110) carves through the snow using the top teeth (103 a) causing the snow between the air pockets to collapse thereby enlarging the air pockets around the wrists; the User (110) drills through the snow with the front tip (103b) by repeated rotational movement of the wrists thereby causing the snow to be cleared in front of the User’s (110) face thus providing User (110) with air to breathe; the User (110) uses the lower gripper(104a) and the bottom teeth (104b) to anchor themselves while they take rest during drilling and continuing the above steps until the User (110) is rendered free from the snow.

It must also be noted that as used herein and in the appended claims, the singular forms "a," "an," and "the" include plural references unless the context clearly dictates otherwise.

[031] Various modifications to the embodiment will be readily apparent to those skilled in the art and the generic principles herein may be applied to other embodiments of an apparatus and method for self-rescue. However, one with ordinary skill in the art will readily recognize that the disclosure for the present invention is not intended to be limited to the embodiments described, but is to be accorded the widest scope consistent with the principles and features described herein.

[0032] The present disclosure relates to an apparatus and method for self-rescue. In one embodiment the self rescue apparatus is a mechanical tool that enables the victim to free themselves while being trapped in an avalanche.

[0033] The User (110) using the self rescue apparatus (100) is referred to as User(l 10) and notations such as top/bottom, front/rear are with respect to the User (110) wearing the self-rescue apparatus (100).

[0034] Figure 1 shows the top front view of the main embodiment of self rescue apparatus (100) consisting of self rescue apparatus (100) consisting of a body (101) and fingerlike projections (102). The finger like projections (102) possess saw-like serrations on the top surface called top teeth (103a) and a front tip (103b) in the front. The lower side of the finger like projections have a curved hook (gripper) (104a) and serrated bottom teeth (104b). The inner surface of the body (101) is affixed with a non-slip padding (105). Each side of the body (101) orthogonal to the finger like projections (103) has at least one strap (106a, 106b) for fastening to the User’s (110) hand. In this embodiment the body (101) comprises at least one and maximum four finger-like projections (102).

[0035] Figure 2 shows the top rear view of the self rescue apparatus (100). In one embodiment of the self rescue apparatus, the non-slip padding (105) is affixed by coating, gluing or bolting the padding (105) to the body (101).

[0036] Figure 3 shows the bottom rear view of the self rescue apparatus (100) wherein rubber pad (105) ensures that the apparatus stays in place in contact with the User’s (110) hand and doesn’t slip when being used. The pad (105) has holes or some design punched in or extruded to provide better grip. The adjustable straps (106) allow proper fit to the wrist of user (110). The straps (106a, 106b) can be fastened by a Velcro or an adjustable side release buckle akin to a watch strap. In one embodiment, there are two straps provided, one beneath the other. In one embodiment of the self rescue apparatus (100) the straps (106) are fastened to each other using one of a deployment clasp, a push button deployment clasp, a fold over push button deployment clasp, a double locking fold over clasp, Velcro or tang buckle.

[0037] Figure 4a shows the top view of the single piece polymer design (100). The present embodiment shows the two parts of the single piece polymer design. In the present embodiment the unibody/one -piece polymer body (101) and the adjustable straps (106) are shown. The finger-like projections (103) along with the front tip (103b), top teeth (103a), bottom teeth (104b) and lower gripper (104a) are embedded in the body. The non-slip padding (105), straps (106) are provided for better grip and side teeth (401) are provided to enlarge the drilled path. [0038] Figure 4b shows the bottom view of the single piece polymer design

(100).

[0039] Figure 5 a shows the top view of the free size design of the self rescue apparatus (100) . In the present embodiment, a rigid handle (107) is absent. Instead an adjustable strap or fixing mechanism is provided. This makes the design free size, unlike other designs with body (101) that require different sizes for different User (110) hand sizes.

[0040] Figure 5b shows the bottom view of the free size design of the self rescue apparatus (100).

[0041] Figure 6 shows the finger grip design variation of the self rescue apparatus (100). This variation showcases a unibody design with cavities for fingers to grab the part instead of a handle (107).

[0042] Figures 7a, 7b, 7c show the variations in the blade structure of the self rescue apparatus (100). Fig. 7a illustrates an embodiment wherein in lieu of a sharp point a curved edge is provided for user safety. Fig. 7b illustrates an embodiment wherein the curved edge has teeth to allow smoother drill while providing user safety. Fig. 7c illustrates an embodiment wherein the blade has a wedge at the rear / user end to act as an anchor while the User (110) corrects their position / orientation.

[0043] In one embodiment of the self rescue apparatus (100) the finger like projections (102) measure between 30-90 mm in length from the knuckles of the User (110) to the tip of the finger-like projections (102) and the entire tool from tool tip to the base of the body measures 100-200 mm.

[0044] In one embodiment of the self rescue apparatus (100) the finger like projections are attached to the body (101) by conventional fastening mechanisms such as snap fit or screws and bolts. [0045] In one embodiment of the self rescue apparatus (100) the non-slip padding (105) is provided with extrusions in different patterns.

[0046] In one embodiment of the self rescue apparatus (100) the front tip (103b) is rounded or pointed.

[0047] In one embodiment of the self rescue apparatus (100) the rounded front tip (103b) is one of serrated or smooth. In one embodiment of the self rescue apparatus (100) one or more wedges are provided at the user end of the finger-like projections (102). In one embodiment of the self rescue apparatus (100) one or more wedges are provided at the user end of the body (101).

[0048] In one embodiment of the self rescue apparatus (100) the method for self-rescue using the self-rescue apparatus incorporates the following steps: the self rescue apparatus is strapped onto the User’s (110) hand, the finger like projections (102) facing outwards, aligned in the direction of the fingers of the User(l lO); the User (110) carves through the snow using the top teeth (103a) causing the snow between the air pockets to collapse thereby enlarging the air pockets around the wrists; the User (110) drills through the snow with the front tip (103b) by repeated rotational movement of the wrists thereby causing the snow to be cleared in front of the User’s (110) face thus providing User (110) with air to breathe; the User (110) uses the lower gripper(104a) and the bottom teeth (104b) to anchor themselves while they take rest during drilling and continuing the above steps until the User (110) is rendered free from the snow.

[0049] In another embodiment of the self rescue apparatus (100) the method for self-rescue using the self-rescue apparatus for User (110) trapped at a depth greater than 1 m. , in addition to the steps disclosed in the preceding paragraph a. the User (110) crawls with every centimetre of space created and anchors the position with User’s (110) knees and toes; b. loosens the snow in the area around the User (110) hips & torso. and by repeating the procedure a and b, the palms of the User (110) will reach the top of the surface; once the palms of the User (110) are out, the User(l lO) pushes the remaining snow away with the help of the blades (103a, 103b, 104a, 104b); once the shoulders are freed, the legs of the User (110) are cleared by pushing the snow away thus enabling self rescue.

[0050] In one embodiment, after mobility is achieved, the user can dig with both the fore limbs which have the self rescue apparatus attached to reach the surface. While carving, loose snow funnels down and settles around the victim. This is avoided as a result of the tool’s lower extension which helps widen the envelope. The lower extension is the tool mounted over the forearms. It ensures that the hole/ puncture created by the front blades of the claw will widen as the carving progresses.

[0052] In another embodiment, the self rescue apparatus is mounted over the feet for better grip and to keep the forelimbs available for gripping and climbing.

[0053] In another embodiment, the self rescue apparatus is mounted on the forearms to keep the hands available for other climbing needs.

[054] In another embodiment the self rescue apparatus is fitted with an ergonomic design of the handle (107) where the palm and fingers can sit/grip comfortably. In the same embodiment, the ergonomic design consists of ergonomic patterns, crests and troughs.

[055] In another embodiment, the ergonomic patterns are in shapes of crests and troughs designed on a rubber sleeve and then assembled with the basic handle (107).
