Description

DEVICES FOR FASTENING ROPE

AREA

The present invention relates to devices for fixing cordage. In particular, the present invention relates to mobile devices for fixing cordage, which enable the device to be attached to a structure which is designed for connection to a body of a person.

BACKGROUND

When sailing, the weight of the crew can be used to reduce the heel of the boat (so-called riding out). While riding, the controls (especially the ropes) that are close to the boat center line are no longer accessible. Sailors can avoid this problem by keeping the rope permanently in hand.

DISCLOSURE OF THE INVENTION

The permanent use of rope in hand can lead to injuries and chronic signs of wear and tear. It can therefore be advantageous to fix cordage by means of a device (with a non-return device) that is tied to the body of the sailor (for example by means of a belt).

A first device according to the invention for fixing cordage comprises a proximal section, set up for fastening the device to a structure which is designed for connection to a body of a person, and a distal section with a first pulley and a first device for clamping the cordage . l The term “cordage” as it is used in the context of the present description and the claims is to be understood in particular as a laid or braided rope made of natural or synthetic fibers. Furthermore, the term “deflection roller”, as used in the context of the present description and the claims, is to be understood in particular as a roller element (e.g. a hollow cylinder or a perforated disk) that is rotatably mounted about a central longitudinal axis of a free end of a clamping element section and that is used for guidance of the rope has a centrally provided circumferential recess and / or a circumferential web on one or both sides.

The distal section can comprise a first curved section with a free end. The first deflection roller is preferably arranged at the free end of the first curved section.

The distal section can comprise a second curved section with a free end and a second deflection roller. The second deflection roller is preferably arranged at the free end of the second curved section.

For example, the first curved section can be provided for use with the left hand and the second curved section for use with the right hand.

The first curved section and the second curved section can be hook-shaped. This makes it possible to avoid situations in which the rope is inadvertently released from engagement with the device (or slips out of the device).

The first curved section and the second curved section are preferably mirror-symmetrical. This simplifies the change of hands.

Preferably, the first curved section and the second curved section partially encompass a flat area, the free end of the first curved section and the free end of the second curved section Partial section limit an access to the flat area and wherein the access extends along a direction coplanar to the flat area.

The access can be on a side facing away from the person's body, so that rope can be introduced into the device by a horizontal movement towards the person's body and, in the inserted state, runs through the device. The access also enables quick release from the cordage by moving the cordage away from the body by means of a horizontal movement through the access from the interior of the device.

The first device for clamping the rope can have a first element (for example a first eccentric) which is rotatably mounted in relation to the first curved section. A clamping point is preferably formed between the first curved section and the first element. The clamping point can be formed, for example, between the first element and the free end of the first curved section. Furthermore, said first element and / or the free end of the curved section can have areas with a structured surface (e.g. grooves, grooves, teeth, etc.).

A second device according to the invention for fixing cordage comprises a clamping element, the clamping element comprising a first clamping element section which is essentially C-shaped, has a free end and a bound end and is designed as a first cordage receiving area. At the free end of the first clamping element section there is arranged a first roller element which is rotatably mounted about a central longitudinal axis of the free end of the first clamping element section. Furthermore, a first holding element which is prestressed with respect to the free end of the first clamping element section is arranged within the first cordage receiving area.

The clamping element can also comprise a substantially C-shaped, a free end and a bound end having a second clamping element section, which is designed as a second rope receiving area. At the free end of the second Clamping element section can be arranged a second roller element rotatably mounted about a central longitudinal axis of the free end of the second clamping element section. Furthermore, an opposite to the free end of the second within the second cordage receiving area

Clamping element portion prestressed, second holding element be arranged.

The first clamping element section and the second clamping element section can face one another.

The clamping element can further connect the bound end of the first clamping element portion with the bound end of the second

Clamping element connecting clamping element connecting portion comprise. The clamping element can comprise a fastening element, preferably arranged on the side of the clamping element connecting section facing away from the first clamping element section and the second clamping element section.

WAYS OF CARRYING OUT THE INVENTION

1 shows a device 10 for fixing cordage 12. The device 10 comprises an essentially L-shaped base body 14 with a proximal section 16 and a distal section 18. The proximal section 16 is for fastening the device 10 to a structure 20 set up that can be tied to the body of a user. For this purpose, the proximal section 16 has a fastening element through which a section / part (such as, for example, a belt) of the structure 20 is guided.

The device 10 further comprises a first device 24 for clamping the cordage 12. The first device 24 for clamping the cordage 12 comprises two pretensioned elements 26a and 26b, which are rotatably mounted in the L-shaped base body 14 (about axes of rotation oriented perpendicular to the plane of the drawing) are. If the cordage 12 extends through a clamping point 36 between the elements 26a and 26b and if a tensile force is applied to the cordage 12 in the proximal direction, the elements 26a and 26b rotate about their axes of rotation (each in the proximal direction). Through the Rotation of the elements 26a and 26b increases the distance between the elements 26a and 26b, whereby the clamping of the rope 12 is released. If the cordage 12 extends through the clamping point 36 between the elements 26a and 26b and if the cordage 12 is subjected to a tensile force in the distal direction, the elements 26a and 26b rotate about their axes of rotation (each in the distal direction) and thereby reduce an area between the elements 26a and 26b, whereby the rope 12 is fixed. The contour of the elements 26a and 26b is not rotationally symmetrical to the respective axis of rotation. For example, the elements 26a and 26b can be designed as eccentrics.

At the distal end of the base body 14, a laterally projecting axis (not shown) is provided, about which a deflection roller 28 is rotatably mounted. The deflecting pulley 28 comprises a hollow cylindrical base body with lateral webs 28a and 28b for guiding the cordage 12. When fetching or lowering the cordage 12 runs over the pulley 28, which facilitates controlled fetching or lowering.

FIG. 2 illustrates a possible modification of the device 10 shown in FIG. 1, which differs from the device 10 shown in FIG. 1 in that the base body 14 is designed in two parts and has a proximal part 14a and a distal part 14b. Both parts 14a and 14b are essentially U-shaped and are connected in an articulated manner (by means of a swivel joint 30) at two free ends. The free ends opposite the swivel joint 30 are connected by means of a lock 32. The lock 32 comprises a latch which is hingedly connected to a free end. The bolt comprises a recess which, in the closed state, partially encloses a projection 34 provided at the opposite end. If a force is applied to the deflection roller 28, the device 10 is secured against unintentional opening.

FIG. 3 illustrates a possible modification of the device 10 shown in FIG. 2, which differs from the device 10 shown in FIG. 2 in that a second clamping point 36 is provided. Both clamping points 36 are Attached to each other laterally offset in order to enable both a guiding of the ropes 12 with the right hand and a guiding of the ropes 12 with the left hand.

4a and 4b show a top view and a side view of a device 10 for fixing rope 12 (not shown) according to a second embodiment. This differs from the devices 10 shown so far in that the distal section 18 comprises a curved section 18a with a free end 18b, the deflection roller 28 being arranged at the free end 18b of the curved section 18a. Furthermore, the clamping point 36 is provided between the element 26a and an inner edge of the curved section 18a. In particular, the clamping point 36 is formed between the element 26a and the free end 18b of the curved section 18a.

As shown in FIG. 5, the element 26a as well as the area of the clamping point 36 at the free end 18b of the curved subsection 18a can have a structured surface (for example grooves, grooves, teeth, etc.). As a result, the risk of the cordage 12 slipping through the clamping point 36 can be reduced.

6a and 6b show a device 10 for fixing rope 12 (not shown) according to a third embodiment. The device 10 for fixing cordage differs from the devices 10 shown in FIGS. 4 a, 4b and 5 in that the distal section 18 comprises a second curved section i8d, which has a free end i8e and a second deflection roller 28 having, wherein the second deflection roller 28 is arranged at the free end i8e of the second curved section i8d.

The first curved section 18a and the second curved section i8d are hook-shaped and mirror-symmetrical to the central axis M. The first curved section 18a and the second curved section i8d partially encompass the flat area 38, the free end 18b of the first curved section 18a and the free end i8e of the second curved section Partial section i8d delimit an access 40 to the flat area 38. The access 40 extends along a direction coplanar with the flat area 38.

The device 10 has a clamping element 42. The clamping element 42 comprises a substantially C-shaped, a free end 18b and a bound end 18c having, first clamping element section 42a, which is designed as a first rope receiving area. At the free end 18b of the first clamping element section 42a there is arranged a first roller element 28 which is rotatably mounted about a central longitudinal axis A of the free end 18b of the first clamping element section 42a. A first holding element 26a, which is prestressed with respect to the free end 18b of the first clamping element section 42a, is arranged within the rope receiving area.

The clamping element 42 further comprises a substantially C-shaped, a free end i8e and a bound end i8f having, second clamping element section 42b, which is designed as a second rope receiving area. At the free end i8e of the second clamping element section 42b there is arranged a second roller element 28 which is rotatably mounted about a central longitudinal axis B of the free end i8e of the second clamping element section 42b. A second holding element 26b is arranged within the second rope receiving area, which is prestressed with respect to the free end i8e of the second clamping element section 42a.

The clamping element sections 42a and 42b are opposite one another, the clamping element 42a connecting the bound end 18c of the first clamping element section 42a to the bound end i8f of the second clamping element section 42b

Clamping member connecting portion 44 comprises. On the side of the clamping element connecting section 44 facing away from the first clamping element section 42a and the second clamping element section 42b there is a Fastening element 22 arranged by means of which the device 10 can be connected to the body of a user.

As shown in FIG. 7, the clamping element connection section 44 can be designed in such a way that gaps S remain between the clamping element connection section 44 and the side of the holding elements 26a, 26b facing away from the clamping point 36, which gaps S are smaller than the diameter of the cordage 12 For example, a section of the clamping element connecting section 44 opposite the access 40 can form a plateau 44a in plan view, through which the cordage 12 is guided in the direction of the clamping points 36 (insertion aid). In addition, the surface of the holding elements 26a, 26b and / or the free ends 18b, i8e of the curved subsections 18a, i8d can be structured.

As shown in FIG. 8, the fastening element 22 can be designed to prevent or at least reduce tilting of the device 10 about a vertical axis, in that the fastening element 22 protrudes laterally beyond the clamping element 42 and is shaped so that the free ends 22a, 22b of the fastening element 22 have an arcuate contour and, when in use, rest in the area of the lateral abdominal muscles of the user. The fastening element 22 can be formed from a rigid material (for example metal, plastic, etc.) or a flexible material (for example a fabric). The fastening element 22 and the clamping element 42 can be designed in one piece or, as shown in FIG. 8, be connected to one another by means of a plurality of connecting elements 22c.

As shown in FIG. 8a, the fastening element 22 can have openings 22d, by means of which a belt (not shown) can be connected to the fastening element 22. Alternatively, a belt can also be screwed to the fastening element 22 or fastened with clips. As shown in FIG. 8b, the fastening element 22 can be significantly wider than the belt (for example more than twice as wide) in order to distribute the load over a large area. Furthermore, as shown in Fig. 8c, the free ends 22a, 22b of the Fastening element 22 can be designed as a wing in order to restrict the mobility of the user (when bending laterally) as little as possible.
