DESCRIPTION

MANUAL EMERGENCY BRAKE FOR FALLS AND ACCIDENTS ON ICE

Object of the invention

The present invention refers to an emergency manual brake for falls and accidents on ice, extensive to hard snow, which, due to its conformation, characteristics and applications, improves everything that is part of the state of the art and the usual articles of use in ski touring and other mountain activities.

Specifically, this invention has as its object a safety tool in falls on ice or hard snow, which incorporates means of quick grip on ice or hard snow to stop the sliding of the falling person and avoid serious mishaps or physical damage.

Technical sector

The field of the technique of this invention corresponds to ordinary necessities of life. In particular, safety in sports, and more specifically in ski mountaineering and other sports in which ice or hard snow can be found.

State of the art

Different tools that act as support and anchoring means when the athlete is in complex situations are known in the market for articles for mountain sports, whether on rock or on ice or hard snow. One of these tools is the so-called ice ax, commonly used in ascents and descents, of which there are several models, all of which coincide in having a head with an interlocking point in the ground and a grip handle. It is a piece that the athlete uses at will, that is, when he is in a situation that requires its use, being an article that is usually carried in the backpack, not in the climber's hand continuously, unless it detects a danger in advance. Therefore, in a situation of fall or unforeseen accident, its grip function is null as it is a piece of difficult access for the athlete or hiker.

on the handle, which implies an element of high risk of accidental cutting when continuously carrying a blade in the hand. In the models in which the blade is removable, obviously in the event of a fall there is no time to mount it to stop the fall.

At the legal level, there are several patents that refer to systems and mechanisms to prevent slipping in mountain skiing on ice, as is the case of the file ES0447818 that refers to a “device to be attached to a boot or ski intended for mountain walking , characterized in that by using elements adaptable to skis or any type of boot that is used, it prevents the skis from slipping on ascents on ice, or allows getting into frozen areas while running on ice, having a resting position on the ski or on the boot that, without hindering, allows the ski to slide on snowy descents or riding with boots on non-icy terrain. " For its part, file ES2400896 refers to a “touring ski with, either in a window, in the tail of the ski or on one side by means of screws, at least one anti-reverse means consisting of a frame, inside which there is a plate arranged Angular tilting section, it has a first section, and a second section, arranged in an angular way with respect to the first one, the vertex of the corner plate being attached to the window by means of a joint, through which an axis of the plate rotates. angular, counting on the face of the window facing the one with the articulation, with a stop, which limits the tilting of the tilting angle plate, achieving a ski that even on very steep slopes there is no backward movement, when the plate is locked in one of the sections on snow or ice. ”.

The aforementioned background describes various advances in the design of safety means in the practice of mountain sports and in particular sports on ice or hard snow, but all of them are means of preventive use to avoid falls, forming part of articles such as skis. , ski boots or snowboards. These systems, although in theory functional for what they are designed, are not useless when the fall has already occurred, and the athlete slides uncontrollably on ice or hard snow, with a more than obvious risk to their physical integrity. .

The applicant is not aware that there is an article that acts as an emergency brake in falls on ice or hard snow, of small size and for personal use.

Thus, the object of this invention is an emergency manual brake for falls and accidents on ice, extensive in hard snow and specially designed for use in ski mountaineering and winter sports in the mountains, conceived as a safety tool intended for reduce and / or slow down the sliding speed in a fall by rubbing blades against ice or hard snow.

This emergency brake is specified in a reduced size tool that comprises a body and hand support, a grip handle, a hand guard and at least one front blade and at least one row of rear blades.

The gripping handle, grooved or smooth, and perforated or not internally, is finished in its upper part by at least one horizontal segment that protrudes laterally and ends with a curved finish, this horizontal segment acting as support for the user's body or hands. .

In its lower part, the grip handle, held by one hand, sits, off-center, on a platform that becomes the hand protector and in whose lower part there is at least one front blade followed by at least one row of blades rear, preferably this front blade being larger in size with respect to the rear blades. This protector separates the hand from the lower blades, avoiding contact with them and therefore the risk of accidental cuts.

The front blade is made up of at least one sheet that is preferably perforated or hollowed out so that the piece is as light as possible and with a variable size, depending on the function it is going to perform in the design. In its most functional embodiment, the front blade comprises two parallel blades with the technical characteristics already mentioned. The rear blades can be distributed in groups of 1 to 4 blades with different angles and sizes, in different areas and equally and emptied or not, depending on their function.

The combination of the position, angle, shape, size and quantity of blades is essential for the correct operation of the brake since they decisively influence whether the braking is more aggressive or softer. In different embodiments, the rear blades are located in central and / or lateral rows or in a combination thereof.

,

support for the body or two hands, a hole for the passage of an elastic cord that keeps it always attached to the backpack or attached to a garment worn by the user, such cord being sufficiently elastic to allow the arm to be stretched at least 110% of its length.

In summary, the claimed brake is made up of the body support or two hands with one or two horizontal segments that extend laterally from the upper edge of the grip handle, which is or is not perforated and whose lower end is seated ta in the hand guard that holds the handle and under which the blades are located.

Preferred embodiment of the invention

According to these drawings, the object of this invention is an emergency manual brake for falls and accidents on ice, its use being extensive in hard snow, in ski mountaineering and winter sports in mountain, which complies, by its design and technical characteristics, the function for which it was conceived.

These figures describe the technical characteristics of the claimed emergency manual brake for falls and accidents on ice, which comprises two specific parts that coincide in any of its embodiments and two parts that, fulfilling the same function, vary in their conformation to adjust to different situations and grip needs depending on the state of ice or hard snow.

In Figures 1, 2, 3 and 4, the preferred embodiment of the brake is shown, with different views that allow understanding its conformation and parts, this brake being a ,, perforated internally or not, which is prolonged in its upper part in a horizontal segment that protrudes on both of its sides and that ends with a curved finish, both segments being the support of the user's body or hands (1). In its lower part, the grip handle (2) sits, off-center, on a platform that becomes the hand protector (3) and in whose lower part at least one front blade (4) is drawn followed by at least one row of rear blades (5), this front blade (4) being preferably larger than the rear blades (5). The front blade (4) is located under the shortest segment of the hand guard (3) delimited by the grip handle (2), while the rear blades (5) are located under the longest segment of said hand guard (3). the hand (3). These blades are formed by a plurality of lines broken at acute angles and all of them are located in the same horizontal plane and with their point of engagement in the same direction. These figures show the inside angle of insertion and pressure on the ice of the front blade (4), in order to have a better grip. The grip handle (2) has in its upper part, close to the point of support of the body or hands (1), a hole (6) for the passage of an elastic cord whose opposite end is attached to an object carried in a fixed way by the user.

Advantageously, and as shown in the figures, the brake is a single piece, without removable components, of great simplicity, with the longitudinal body of rectangular conformation that forms the extended grip handle on both external sides in perpendicular platforms that make up the point upper support for the body or hands of the user, and the flat surface intended to be a protector and support for the hand of said user.

In view of these figures, it is obvious that this tool that constitutes a manual and emergency brake for falls on ice or hard snow consists of four parts, each of them fulfilling its function in any of its embodiments, with two parts that maintain an identical shape, the grip handle (2) with its hole (6) for the cord and the hand protector (3) and two other parts that can be varied, the body and hands support (1) with a single side segment or with two side segments and the blades, varying both the shape of the front blade (4) and the rows and shape of the rear blades (5), which admit different combinations, for example an intermediate row with more blades. pronounced and two side rows with shorter blades or two side rows with longer blades and one center row with shorter blades, or all the same rear blades or any other combination. In these figures, ,

anchored in ice or hard snow in this example and being preferably larger. For its part, the rear blades (5) are more compact than the front ones (4).

The use of the described brake is simple and intuitive since, considering the risky situation in which they find themselves, the user does not have time to think and must react quickly and safely to pick up the tool and apply it.

At the moment of the fall, the first fundamental movement is to grasp the tool by the grip handle (2) with the strongest arm and hand.

The second movement is to lightly drive the front blade (4) into the ice or hard snow, holding the arm and hand firmly until the control of the fall begins, and the body, without any effort , is naturally placed in the correct position to initiate braking. Thanks to its design and shape, the tool locks into the ice without much effort.

Once the front blade or blades (4), normally larger, have been nailed in, the user must pull with the arm that holds the grip handle (2) while placing the free hand on the body and hand support ( 1). At this time, the tool is held by both hands of the user, who loads the weight of his body on them, which translates into greater friction of the brake on ice or hard snow, partially or totally reducing the speed of the sliding, managing to stop the fall and stop it. The hand guard (3) prevents the hand holding the grip handle (2) from touching the ice or any sharp element on the blades (4) (5). Once braking begins, the force of the weight is combined between the hand guard (3) and the support of the body and hand (1).

As indicated in the figures, it is important to point out that the support for the user's body and hands can be simple, present on only one side of the handle, or double, present on both sides of the handle, which allows a greater force to be applied. about the tool.

In view of this explanation, it is obvious that the tool must be located in an easily accessible area, without disturbing the user who carries it. For example, housed in a cover located on the anatomical shoulder straps of the backpacks in the chest area. For its size and ,

standard backpack provided it is a place of quick access.

A fundamental element for the control of the brake is the elastic cord attached to the handle and that links it to the chosen clamping point. In the event that the user lets go and loses physical touch with the tool, the elastic cord ensures its return, allowing the user to retrieve and use it.

As mentioned above, the tool described is an article designed for exclusive use in emergency situations, in unexpected falls on ice or hard snow in which the ice ax is not accessible due to different circumstances, for example, that it is stored in the backpack or lost in the fall, and that the usual emergency braking techniques in the fall are not useful. This novel tool has a specific use in specific situations of unforeseen falls, it can never replace the use of the ice ax, or any other safety element in the mountains, since they are elements of a different nature and function.

The target of users of the new tool are mainly mountain skiers and other sports with significant risk of falls, as can occur while practicing mountaineering or trailrunnig, its use being extensive for groups such as cyclists, runners, climbers or hikers who can be found on terrain with risk of falls.

At the production level, the claimed brake can be manufactured in a single material such as metals, plastics or wood or by combining different materials.

It is not considered necessary to make this description more extensive for any person skilled in the art to understand the scope of the invention and the advantages derived from it. The materials, shape, size and arrangement of the elements will be subject to variation as long as this does not imply an alteration in the essentiality of the invention. The terms in which this report has been written should always be taken in a broad and non-limiting sense.
