    Summary
    In order to provide a quick-release carabiner with a simple design and a carabiner body (10) and a locking catch (20) rotatably mounted on the karabiner body (10) for releasably locking the karabiner, which can also be opened under tensile load, the invention provides that the locking catch ( 20) is horizontally load-bearing for receiving a webbing, in order to absorb the tensile load of the webbing in the closed state of the karabiner and that the locking catch (20) can be opened under the action of the tensile load in order to detach the webbing from the karabiner.

    Description: The invention relates to a carabiner of the type one
    Quick-release carabiner, with which it is possible to separate the two interconnected elements in an emergency under tension.
    In the quick release carabiner of this application, the second of the interconnected elements (webbing) is hung directly in the horizontal snapper and this is locked and secured by means of a rotatable bayonet catch.
    Locking and securing takes place in the form of a "single action" that means that at the end of the locking movement without further action the locking lever with the bayonet is secured against unintentional opening by a spring-loaded locking pin.
    The opening of the carabiner is done by a "double action" that means the release button must be pressed and the locking lever with the bayonet can be turned to open.
    The system has already been verified for its function and mode of operation in practical tests on the paraglider when the parachute is released by the applicant of the invention.
    A distinction is made between conventional carabiners, load-separable carabiners, load-separable systems that are not carabiners. (e.g. three-ring system) and a special design, the Pin Lock carabiner developed by Finsterwalder.
    There is currently a quick release carabiner on the market which is manufactured and sold by Finsterwalder. There is a trademark application under the name "Quick out". The system is not protected by patent law and the principle of operation differs greatly from the present application.
    Conventional carabiners:
    Conventional carabiners are essentially a C-profile open on one side, the snap is on the side and closes the open C-profile. The snapper or its safety catches under load. Due to the design, a separation of the two interconnected elements is not possible under load, nor is it desirable.
    Finsterwalder quick-release carabiner "Quick out" The quick-release carabiner from Finsterwalder is used in paragliding, in fire brigades and in the military sector and has the advantage that the two interconnected elements (harness / rope or harness / paraglider) are separated even under load can. In paragliding, this is used to separate the main glider after the parachute has been deployed. This is particularly advantageous in the case of controllable rescue parachutes, since the partially opened main parachute, which is
    2/191 is still under tensile load, which can greatly influence and disrupt the controllability of the reserve parachute.
    The Quick out carabiner has the following disadvantages:
    High weight of 205 grams per piece.
    To connect the two elements, the carabiner must be partially disassembled and part of the separation system screwed to the element to be separated. This part is called "use".
    Closing and securing are separate processes, the securing must be operated separately after the insert has snapped into place. If the safety device is not closed, the carabiner can be triggered by an unintentional handle movement.
    Hanging the harness e.g. on a simulation hanger to test or to adjust the belt lengths is not possible without mounting the insert part of the quick out on the hanger.
    Three ring systems:
    Three-ring systems are mainly used as a quick disconnect system in parachute sports.
    Advantages of the three-ring system:
    The pilot completely separates both risers of the parachute with a single pulling movement and is again in undisturbed free fall when opening the rescue parachute.
    The three-ring system has the following disadvantage:
    It is not suitable for the paraglider area for approval reasons, since the separation takes place before the rescue parachute is released, but a free fall of the paraglider pilot is not covered in training or underwriting. Use in paraglider harnesses is therefore not possible.
    Special design Finsterwalder "Pin Lock" [0018] The Pin Lock carabiner from Finsterwalder has a pin as a horizontal locking bolt which is slidably guided for locking via the axis x defined in the application.
    The Pin Lock carabiner has the following advantages:
    The one-sided open C-profile of a conventional carabiner is eliminated, which represents a risk of fatigue. The reason for this special design was the increase in fatigue strength.
    The Pin Lock carabiner has the following disadvantages:
    This carabiner can not be separated under load, since the frictional forces are too high and when pulling the pin under load and loss of bilateral storage, the pin is bent and further unlocking is not possible.
    [0023] Note:
    The Pin Lock carabiner also has the locking screw (11) of the present application to prevent the opened carabiner from falling out of the harness loop. The locking screw is not relevant to the patent and is therefore not described further.
    Quick-release carabiner of the subject application [0025] Advantages of the quick-release carabiner of the subject application:
    Construction-related low weight.
    Compared to the quick out, a weight reduction of around 60% is achieved.
    The carabiner is a coherent assembly both in the closed and in the open state. No component has to be attached to the element to be separated. The use of tools is eliminated. The paraglider can be changed at any time without assembly or disassembly work.
    The harness can be attached to a simulation hanger at any time, for example to adjust the belt lengths.
    Closing and securing are designed as "single action", so closing the fuse cannot be forgotten.
    The securing takes place in one movement with the closing of the locking lever and is realized by a spring-loaded pin.
    The opening of the Karabinersjst designed for security reasons as a "double action". To open it, the safety pin must be pressed with the release button. Pressing the release button does not open the carabiner.
    The bayonet lever must also be turned to open it. It is not possible to operate the lever without pressing the release button. All conceivable unintentional grip movements that can occur in flight therefore do not lead to an unintentional opening of the carabiner.
    [0032] Note:
    The carabiner will be produced and sold by Finsterwalder, as a supplement to the controllable cross cap (rescue parachute), patent no. 518 554, issued on November 15, 2017.

    Carabiner as an entire coherent assembly Task In order to avoid assembly work, loss of parts, use of tools and to achieve greater flexibility when exchanging umbrellas or adjusting work on the harness, the carabiner is carried out without a separate counterpart.
    Technical implementation [0042] The locking catch (20), which in the open state enables the belt or rope to be attached, is carried out horizontally and rotatably supported on one side about the axis z and therefore always remains connected to the assembly.
    In contrast to conventional carabiners, where the locking snap is arranged vertically and is only responsible for the positive locking of the open C-profile and as a safeguard against slipping out of the webbing in the unloaded state, the locking snap (20) on the quick-release snap hook is the subject of the application the horizontal position in the closed state also designed as a seat belt.
    Locking by means of a bayonet Task [0045] In order to close the horizontally lying locking catch (20), which can be rotated on one side, it must be locked reliably on the opposite side and, above all, under load, in a separable manner.
    Technical implementation The opposite end of the locking snap (20) is designed so that it can move through an opening (13) in the carabiner body (10).
    The opening (33) of the bayonet lever (30), which can be rotated about the axis x, is aligned with the opening (13) in the carabiner body (10) in the open state, with which the karabiner catches its position for the closed state. In this position of the locking catch (20), the carabiner is still open, therefore it is neither locked nor secured.
    The locking snap (20) is held by rotating the bayonet lever (30) about the axis z after the positioning of the snap in the bayonet.
    Securing the bayonet lever with securing pin Task [0051] The bayonet lever (30) is designed in such a way that the carabiner is closed and locked with an intuitive movement.
    Technical implementation The bayonet lever (30) is rotatably mounted about the axis x.
    The securing pin (12) is guided linearly in the spring spring along the x axis.
    The bayonet lever (30) has an inclined sliding surface (32) on which the securing pin (12) slides when it is closed. The bayonet lever has a bore (34) in which the securing pin (12) can snap into place and secure the carabiner against unintentional opening.
    Unlocking the bayonet lever with unlocking pin Task [0058] The securing of the bayonet lever (30) is released by the unlocking pin (31) without the carabiner opening.
    Technical implementation In the bayonet lever (30) a spring-loaded unlocking pin (31) is installed, which is linearly guided along the axis x when the unlocking is pressed, which is connected to the unlocking pin (31), presses the locking pin (12) out of the hole (34) in the bayonet lever (30). The carabiner is still closed and the rotational movement of the bayonet lever (30), which is rotatably mounted about the axis x, is released.
