The technical field

The invention relates to a safety device for regulating and blocking moving inside the ropes.

Under the "safety device" means a safety device used mainly in climbing equipment, but not only, by means of which the first climber controls and blocks holding the rope used to belay the second climber.

These devices, known in the field of mountaineering as a "safety device", can be used as on-site mountaineering and climbing wall, and help in case of danger to ensure the safety of the climber, blocking secure the rope to which it is attached, thus preventing his fall.

In fact, these devices are typically used to belay climbing wall climber companion on earth, in the field called "insurance", which prevents free fall of the climber with a safety device in case, if during the ascent, the climber will make a mistake with the consequent loss of grip hands.

This technique is known as "insurance lead climber" in which the lead climber, starting to rise, insured companion on earth, namely insurance, with the help of the safety device, which in the event of an accident can block attached to the climber holding the rope. While the climber attaches the rope to one or more ring located at the climbing wall, during a gradual ascent.

Also known other safety device that is capable of blocking holding the rope in case of an accident, in particular, when the belayer can also perform its function while on a climbing wall.

For example, can be applied to the device to belay the second climber. In this case, the lead climber on the climbing wall acts as a belayer and using a safety device controls the holding rope to which is attached a climbing wall below the second climber. In the case when the second climber loses his grip hands, belay device, attached to the top climber, provides the block holding the ropes, preventing thereby the fall of his companion.

It is also well known how to use these devices as a trigger device, in other words, for the descent to overcome the wall. In fact, the climber, bearing mounted thereon a device that uses the ability of a safety device for blocking moving inside the ropes and subsequent regulation is aniu the speed of descent suitable means, in the case of the supply of devices, or just manually changing the friction force acting on the rope in the device.

The level of technology

Known safety devices regulate the movement of the rope and block it by means of braking, usually creating friction. Thus, it is possible to regulate the movement, slowing or blocking the movement of the rope and thus preventing the fall of the insured of the climber.

Known manually operated device or a semiautomatic device, which in case of an accident with a sudden tension on the rope due to the fall of the climber automatically locks into the emergency position, in which the rope is blocked.

In manually operated devices, on the contrary, in the case of the fall of man, with an attached device for insurance partner at the climbing wall must manually move holding the rope in the position in which the device could slow its movement and to carry out blocking.

For example, a managed manually belay device DOUBLE V-ROW, commercially available "Aludesign SpA company, equipped with a nozzle convenient form, the body of which the rope is held firmly in the case of a falling climber. Special hull shape allows you to create friction of the rope, thereby limiting the force required to lock the rope hand is th man ensuring the safety of the fall of his companion.

This type of safety device despite its cheapness provides a level of security and efficiency of blocking pitches, depending on experience and professionalism using the device of the person, i.e., insuring, ensuring the safety of companion. In addition, after reaching the position of blocking pitches, the user must firmly to keep the rope in his hand, preventing its movement in the body and thereby making the blocking of the rope by friction.

Semi-automatic or effect a safety device is the model GRI-GRI model", manufactured by campaign Petzl company".

This device is equipped with an eccentric Cam, around which passes the restraining rope. A Cam attached to the structure of the device can be rotated so that in the event of an accident, when subject to insurance climber falls, the tension holding the rope will cause rotation of the Cam in the locking position. In this position, the Cam pulls holding the rope between itself and the fixed surface of the device. The device also has an arm, allowing the achievement of the provisions of the lock to adjust the level of braking, carrying a small rotation of the Cam in the opposite of the one direction relative to the direction, providing tension on the rope to lock it. For example, use the handle when the device is used as a trigger device for regulating the speed of descent, partially blocking the rope.

Describes a safety device, which is essentially a semi-automatic device type, provides a higher level of security compared with a controlled manually by the device, since the achievement of blocking the rope position occurs automatically due to the tension holding the rope with the weight of the falling down of the climber.

However, to ensure efficient operation of both manual and automatic devices require holding the rope in a predetermined position by the person applying the device to insure another climber.

In fact, both ends of the rope, incoming and outgoing from the device, in order to avoid any problems with achievement of blocking the rope provisions should be maintained in the correct position relative to the device.

Automatic devices are not particularly reliable when using the arm when required partial exemption rope.

The task of the invention to provide a safety device which guarantees a high level of reliability when locking the retaining cords at any at is the condition of use and with controlled size and weight.

In particular, the device according to the present invention is a hand-held or effect type and provides automatic blocking of the rope after the sudden strengthening of the tension caused by the fall of the insured climber and the user (insurance), holding in one hand the free end of the rope.

An additional challenge is overcoming the problems of the known semi-automatic devices, in particular the improvement of safety and reliability, when blocking pitches, and its subsequent partial exemption, for example, when you want to give part of the rope insured climber or when the device is used as the trigger.

An additional object of the invention is to develop a safety device capable of blocking pitches when the user unintentionally wrong it enters.

An additional objective of this invention to provide a safety device for the implementation of blocking pitches.

Disclosure of inventions

A safety device for locking the rope according to the present invention contains a main body made of two preferably located in parallel planes of flat plates fastened together multiple fasteners, preference is sustained fashion four spaced pins.

The rope is introduced into the housing of the device, optionally containing an attached carabiner through the hole in the housing of the device.

The carabiner clip allows you to secure the safety device of the user and configured to move along the hole between nonblocking rope position, which is the condition of normal use, and an emergency position in which the rope is blocked, and Vice versa.

The shape of the hole divided by at least one protrusion into two areas, however, when the carabiner is located in the first area, the device is in non-blocking rope condition, and when the carabiner is located in the second area, the unit is in an alarm state in which the rope is locked.

The device also includes means to prevent accidental movement of the rifle along the holes, preferably representing a movable arm mounted by means of the spring opposite the ledge separating the loop holes. For this reason, the movable lever prevents accidental movement of the carabiner from the first plot holes in the second plot holes and Vice versa.

To lock the rope in an emergency situation, the device comprises at least one blocking element, which together with carabiner creates it is possible friction.

In fact, when the carabiner is located in the second section of the hole, the rope is blocked due to its friction between the carbine and the blocking element.

The special shape of the holes of the plates forming the housing of the device, in particular, the presence of ledge, helps to protect your device from accidental and unwanted blocking of the rope or emergency condition during normal operation.

In fact, the supply device of a movable lever prevents movement of the rifle along the hole, eliminating the risk of accidental transfer of nonblocking rope position to the emergency position, in which the rope is blocked, and Vice versa.

Additionally, as noted above, the safety device can also work as a trigger device, guaranteeing used in this way, high reliability and security.

Unlike traditional automatic safety devices in the device according to the invention has no arms or similar means for the regulation of blocking pitches, for example, when descending from the wall. In fact, a partial exemption of the rope is only the movement of the hand on the device, this avoids the problems, for example, using the arm for the implementation of such action.

More the features and advantages of the present invention will be better understood from the further description with reference to the drawings.

The implementation of the invention

As shown in Fig.1, a safety device according to a preferred variant of its implementation contains the main body 1, consisting of two flat plates 2 and 3 are fastened together multiple fasteners 4-7.

Flat plates 2 and 3 are similar to one another and made of a metal material having high mechanical properties and low weight.

Plate bonded to one another so that between them is formed a space for passing passing inside the ropes.

In the form shown in the drawings, the embodiment of the invention, the plates preferably lie in two PA is allelic planes and tightened by four spaced pins 4-7, made from metal material. As shown in Fig.1, in the housing of the safety device is made the hole 8, the contour of which has a certain form, through which, as will be described more below, the device may be in the first non-blocking rope condition in which it can move freely, or the second locking the rope or emergency condition.

The shape of the hole 8 on both plates 2 and 3 has a protruding section formed by the protrusion 20, the separating hole 8 on the two respective section 21 and 22, and the first section 21 is under the ledge 20 and second section 22 above the ledge 20.

Both bonded to one another, the plates 2 and 3 form the housing 1 of the device, the side surface of which is partially closed by a plastic covering section 9 having an appropriate shape to place on the side surface of the device body so as to close the space between the two plates.

As shown in Fig.1, section 11 of the side surface of the device open for access restraint rope 10, which is injected into the device in the space between the two plates 2 and 3.

In Fig.2 shows the operation of the rope 10 in the device. In particular, holding a rope attached U-shaped for insertion through the opening 11 of the outer side p of the surface of the device until until it reaches the bottom of the housing, as shown in Fig.3.

The rope 10 must be correctly entered into the device, so that the end 10A, i.e., the end that passes over the stud 4, was attached to the insured climber, and the end 10b, passing over the pins 5 and 6 and which is the free end of the rope, gradually moved in the device, while the climber ascends the wall.

The correct operation of the safety device according to the present invention provides the use of the carbine 15 or equivalent connector, which is attached to the device after entering the holding rope, as described previously with reference to Fig.2.

As shown in Fig.3, a conventional carabiner clip 15 is attached to the body 1 of the device, letting it open through the opening 8 in the housing of the device.

Carbine 15 performs the double function of holding the device on the user (hedges), hedges of the second climber in the event of a fall, and additionally interacting with the device itself to ensure blocking of the rope.

In other words, there is no need for additional hooks or equivalent means for attaching the device according to the invention to the user, insuring companion.

As will be understood, in particular, the description of the operation of the device, carabiner clip 15 attached to the device by carrying capacity, the project through the opening 8, can be moved along the opening between the first section 21 and second section 22, and Vice versa. When the rifle is in the first area 21 of the hole 8, as shown in Fig.4, the device is in the blocking of the rope condition, in other words, in the normal state in which the rope may be freely held within the housing 1 of the device.

When the rifle is in the second section 22 of the hole 8, as shown in Fig.5, the device is in an alarm condition and the rope is locked, thereby preventing its movement.

A safety device is semi-automatic only if the user holds in one hand and loose rope, i.e., its free end. If the insured climber falls, the user (belayer) holds in one hand the free end of the rope and carabiner 15 automatically snaps into locking position. In fact, in the event of a fall, the end 10A, after the rope is subjected to tension, exerted force to the rifle, causing it to move along the hole 8 of the first section 21 and second section 22, whereby the device goes into alarm state, and subsequent movement of the rope is prevented.

Inside the housing 1 a safety device, i.e., within the space bounded by two plates 2 and 3, installed interlocking the first element 12 and a means for preventing accidental movement of the carabiner 15 of nonblocking rope position to the emergency position and Vice versa.

The blocking element 12 is secured in position on the pins 5 and 6 and is the element that provides together with carabiner 15 blocking pitches, when the rifle is moved to the second section 22 of the hole 8 due to the tension of the rope caused by the fall of the insured climber, and that the user (the insurer). hold the free end 10A of the rope. As shown in Fig.1, on the surface of the blocking element 12 in contact with the rope, made a V-shaped notch 45 or equivalent element for increasing the friction created on the rope to more effectively carry out its blocking.

In particular, as seen in Fig.5, when the device is in the blocking of the rope 10, the rope is located between the blocking element 12 and 15 carbine, located in the second section 22 of the hole 8. The movement of the rope 10 is blocked due to friction carabiner clip 15, which is pressed against the blocking element 12 when the tension on the rope 10.

Means for preventing accidental movement of the carabiner 15 is a movable arm 13 mounted to rotate on the end of the blocking element 12. In particular, the lever attached to the blocking element 12 by a spring, not shown in the drawings.

Spring loaded so as to exert pressure on the movable arm 13 DL the location opposite the tab 20 in the hole 8.

In other words, pre-loading of the spring will determine the rotation of the lever 13 so that the latter was located in the Central part of the device.

The lever prevents movement of the carabiner 15 of the first section 21 and second section 22 of the hole and Vice versa, affecting only a rope, or only on the carbine.

When the device is in non-blocking of the rope 10 and the carabiner 15 is in the first area 21 of the hole 8 (the position shown in Fig.4), the movable arm 13 by pre-loading the spring presses on the site 10C rope and carabiner 15 so that the latter will be under the ledge 20, which prevents its movement along the hole 8.

Thus, the person to which is attached a device that can keep the rope moving inside the device without the risk of accidental movement of the carabiner 15 in the second position 22, the blocking of the rope.

Pre-loading of the spring is such that under normal conditions it prevents accidental movement of the carabiner 15.

In emergency conditions, the force applied tight rope 10 to 15 carbine, capable of exceeding exerted by the spring pre-loading, moving the movable arm 13 to provide moving carbine 15 along the holes 8 to achieve the blocks of the respective rope position in the second area 22 (Fig.5).

After the location of the carbine in the second section 22 to lock the rope 10 is movable lever 13 is released, returning to the position in which it is located opposite the protrusion 20 of the hole 8. If necessary, return the device in non-blocking rope condition, the user can manually move the device so that the carabiner 15 moved along the hole 8 of the second section 22 in the first section 21.

To perform this operation must be created such force that exceeds a pre-loading spring rolling lever to cause, so its temporary movement and to prevent movement of the carabiner 15 to tab 20. After returning carbine 15 in the first section 21 in nonblocking rope lever again occupies the position in which it is located opposite the tab 20 to prevent accidental movement of the rifle in the blocking position during the new stage of the application.

As described above with reference to Fig.2 and 3, the rope 10 must be properly inserted into the device. If the rope is incorrect, in other words, when the end 10b, passed over the studs 5 and 6, attached to the insured climber, and the end 10A is a free, belay device according to the present invention is able in any case to ensure that blocking is their rope and prevent the fall of the insured of the climber.

Indeed, as shown in the drawings, the upper portion of the plates 2 and 3 on pin 4 has a recess 50 on each of them to ensure blocking of the rope when it was introduced inside the device correctly.

In case of a fall insured climber incorrectly mounted thereon, the end 10b is stretched, but the device snaps into place in the emergency state or in any case not be able to create such friction to ensure the blocking of the rope.

Under the action of the tension caused by the weight of the falling climber, the free end 10A of the rope tends alone or in any case under the influence of a user standing partner, be located so as to be in one of two recesses 50, ensuring that the friction on the rope, causing her blocking. The notches 50 are of the proper form in order to facilitate the location inside of them end 10A of the rope and to create sufficient friction to implement the block.

However, it is necessary to clarify that the notches 50 ensures the blocking of the rope provided by incorrect use, which should not be preferable shown on the drawings variant, according to which the end 10A of the rope passing over the pin 4, is an end attached to the insured climber.

the purpose of the explanation here will be described the working phases of a safety device according to the invention in the case when the device is applied to cover the first climber of the associated rope group. As noted earlier, this technique assumes that the person on the land or on the climbing wall with the device attached carabiner 15, will insure the first climber ascending the wall.

First of all people on earth must enter the rope in the device and lock carabiner by passing it through the hole 8, as described above with reference to Fig.2 and 3.

Then people on earth secures the device on himself in nonblocking rope condition by fixing carbine 15 on your seat belt or a special tape that is normally used in the equipment of the climber.

The purpose of man on earth is to provide for the gradual movement of the retaining rope inside the device, when the climber ascends, i.e. in ensuring the movement of the free end 10b inside the device for its submission to the climber is attached to the end 10A.

Man on earth provides the climber with a rope, applying a known method lies in the cessation of holding in one hand a safety device and using the hands to regulatory sections of rope above and below the device, i.e. the free end 10b and the end 10A used insurable climber.

In case of an emergency, i.e., in the fall insured climber, people on earth holds loose the rope, i.e., its free end 10b, and the device due to the force transmitted stretched the rope to the carabiner, automatically switches to the blocking state by moving carbine 15 along the hole 8.

In fact, when the climber weakens the grip, resulting in the fall, attached to the end 10A of the rope is stretched due to the weight of the climber. This sudden increase in tension of the attached end of the rope moves carbine 15 along the holes 8 under the force transmitted by the rope, trying to exit the device.

The force developed by the rope when the tension is sufficient to overcome the opposing force of the spring movable arm 13, whereby the carabiner 15 is moved to the second section 22 in locking the rope position. In particular, the cord is located between the blocking element 12 and 15 carbine.

Thus, the rope is blocked primarily due to its friction between the element 12 and 15 carbine.

In an emergency situation, for the partial weakening of the rope can be lowered her friction between 15 carbine and a locking element 12. For implementation of this operation the device has no arms or similar de is Aley, as in conventional devices.

The user operates the device manually using the groove 30, is made on the section of plastic material 9, the moving body 1 of the device in the direction shown by the arrow F in Fig.5.

It should be noted that the groove 30 contributes to this capture, which reduces the friction of the rope when the device is in the blocking condition, and is intended to further regulate the movement of the rope with the manual movement of the device in the direction of the arrow F, in other words, in order to limit the friction of the rope located between the blocking element 12 and 15 carbine. Pressure is applied manually on the groove 30 on the merits is the rotation of the device to the free end 10b of the rope (Fig.5), causing a reduction in friction of the rope between the blocking element 12 and 15 carbine.

Adjustable movement of the rope used when the device is in the blocking position, for example when it is desirable to give a little rope a fallen climber, again caught hold of the rope, or if the device is used as a trigger device.

Manual action of the user with the device under tension rope actually will move a fixed blocking element 12 relative to the carabiner 15 essentially pre is her position. Thus, rotation of the blocking element 12 relative to the carabiner 15 modifies the friction force acting on the rope, causing her moving.

Depending on the movement by the user of the device can be obtained managed, more or less noticeable movement of the rope.

Undoubtedly, it should be understood that it is possible to attach more than one device according to the present invention so that they are adjacent to each other in one plate.
