Description

[0001] The invention relates to a device for storing a tendon.

[0002] The device is used, for example, to store the bowstring of a sports bow.

[0003] The object of the present invention is to provide a device that enables improved support of a tendon.

[0004] This problem can be solved, at least in part, by a device according to claim 1. The dependent claims describe embodiments of features that may offer additional advantages.

[0005] A device for storing a bowstring is described. The device comprises a first component and a second component. The first component has a bearing surface for the bowstring and a first fastening element. The second component has a second fastening element. The first fastening element and the second fastening element are each designed to receive one end of the bowstring. The first component and the second component are connectable to each other in such a way that they are movable relative to one another, with the two fastening elements being designed and arranged such that a relative movement of the two components relative to each other tensions the bowstring held by the two fastening elements.

[0006] In this description, the term "tendon" is to be understood as "thread- or cord-shaped material" or "thread- or cord-shaped body." The device is designed to allow the storage of any type of flexible thread- or cord-shaped material or body.

[0007] The string could, for example, be the bowstring of a sports bow. Such a string might have a loop at each end, which is attached to the bow's limbs during use. During storage using the described device, these loops can, for example, be hooked onto one of the device's fastening elements. The bowstring of a sports bow is merely one specific embodiment of a string. However, the device is not limited to storing such bowstrings. Any type of flexible thread- or cord-like material or shape can be stored using the device. Other embodiments include kite strings, fishing lines, fiberglass or metal threads, cables, or similar materials.

[0008] The fastening elements can be, for example, hooks designed to receive these loops. The hook represents only one specific embodiment of a fastening element. Any other design of the fastening element that allows the tendon to be attached to the device can be used instead of or in addition to the hooks. Further embodiments include, for example, wedge clamps or undercuts. The wedge clamps can, for example, have a V-shape.

[0009] By moving the two components relative to each other, the relative position of the two fasteners can be changed. Increasing the relative distance between the two fasteners can pre-tension a string held by the fasteners, preventing it from kinking and slipping off. Conversely, decreasing the relative distance between the two fasteners can release the pre-tension, allowing the string to be removed from the fixture.

[0010] Such a device allows the bowstring to be stored in a way that prevents it from being kinked or bent with an excessively small radius, thus reducing or preventing damage. Furthermore, this type of device allows for storage in a compact space. Storing the bowstring in a disassembled state is necessary because permanently storing it while it is strung on the bow will cause undesirable stretching over time. Therefore, storage on the device described here also improves the bowstring's lifespan.

[0011] The first component and the second component can, for example, be connected to each other in such a way that the two components are inserted into each other in one direction parallel to a common central axis.

[0012] According to one embodiment, the device has a coil shape. This allows the bowstring to be wound around the device, thus reducing the space required for storing the bowstring. The diameter of the coil-shaped device can be selected such that no kinks or bends with an excessively small radius occur in the bowstring when it is wound for storage. This reduces the risk of damage to the bowstring during storage.

[0013] According to one embodiment, the relative movement of the two components is a rotation about a common central axis. For example, the first component can be rotated relative to the second component in a first direction about the common central axis, thus changing the position of the two fasteners relative to each other. Increasing or decreasing the relative distance between the two fasteners allows, as described above, the pretensioning or loosening of the tendon.

[0014] According to one embodiment, the first component has a first contact surface designed to abut the second component. This enables the second component to be received and thus a connection between the first and second components. The first contact surface can, for example, be a surface along the inner diameter of the first component.

[0015] According to one embodiment, the first contact surface has a surface profile designed to prevent unintentional movement of the first component relative to the second component. The first contact surface can, for example, have a grooved, serrated, or corrugated surface. However, the surface profiles are not limited to these; any surface profile that prevents unintentional movement of the first component relative to the second component can be used.

[0016] An unintentional movement of the first component relative to the second component can, for example, be a movement in a direction parallel to a central axis or a movement around a central axis. In particular, such an unintentional movement can cause a relative movement of the two fastening elements to each other, which can lead to an undesirable loosening of the tendon tension and cause the tendon to slip off the device. A suitable surface profile of the first contact surface reduces the risk of such movement or prevents it altogether.

[0017] The contact surface and its corresponding surface profile do not prevent intentional movement of the first component relative to the second. By applying a suitable force, the two components can be moved relative to each other, for example, to pre-tension or release a pre-tension on the bowstring. This allows for improved support of the bowstring on the fixture and its removal from the fixture. In particular, intentional relative movement of the two components in one direction around a common central axis is possible to create or release a pre-tension, and intentional relative movement of the two components in one direction parallel to a common central axis is possible, for example, to assemble or disassemble the fixture.

[0018] According to one embodiment, the second component has a second contact surface designed to abut the first component. In particular, the second contact surface of the second component can abut the first contact surface of the first component. This enables a connection between the first and second components. The second contact surface can, for example, be a surface along an outer diameter of the second component.

[0019] According to one embodiment, the second contact surface has a surface profile designed to prevent unintentional movement of the second component relative to the first component. The second contact surface can, for example, have a grooved, serrated, or corrugated surface. However, the surface profiles are not limited to these; any surface profile that prevents unintentional movement of the second component relative to the first component can be used. The surface profiles of the first and second contact surfaces can be matched and, for example, form corresponding counterparts. As already discussed in the context of the first contact surface, the second contact surface also allows intentional relative movement between the first and second components and prevents unintentional movement of the two components relative to each other.

[0020] According to one embodiment, the first and second fastening elements are of different sizes. Bowstrings can have different ends. For example, the bowstring of a sports bow can have loops of different sizes. By using appropriately adapted fastening elements, the risk of damage to the bowstring, especially to the bowstring ends, such as the loops, can be reduced. The fastening elements can be marked accordingly, for example, with a number, to reduce the risk of incorrectly aligning the bowstring ends with the respective fastening element. Furthermore, the fastening elements can be shaped in such a way as to prevent incorrect alignment of the bowstring ends with the respective fastening element.For example, a fastener may be of such a size that only one of the two tendon ends can be accommodated by this fastener, while the other tendon end may be too small to be accommodated by the fastener.

[0021] According to one embodiment, at least one of the first component and one of the second component have a limiting element configured to define the bearing surface of the first component in such a way as to reduce or prevent movement of the bowstring relative to the bearing surface. In particular, both the first component and the second component can have a first limiting element, so that the bearing surface of the first component is bounded on two sides. The limiting elements can, for example, be configured as walls extending perpendicular to the bearing surface, thus limiting the bearing surface in such a way that the bowstring cannot slip off the bearing surface. Such limiting elements improve the mechanical protection of the bowstring supported on the device.For example, such limiting elements can prevent mechanical contact with the tendon, such as contact with the tendon by other objects or the user. This can further improve the lifespan of the tendon.

[0022] The fastening elements can be integrated into the boundary elements, for example. Hooks can be recessed into the walls. This reduces the space required for storing the bowstring. The boundary element can have corresponding recesses in the area of ​​the fastening elements to reduce or prevent damage to the bowstring, for example, from friction against an edge of the boundary element.

[0023] According to one embodiment, the device further comprises a third component designed to clamp the first and second components together. The third component is specifically designed to prevent unintentional movement of the first component relative to the second component. In particular, the third component prevents the unintentional disassembly of the first and second components from each other. The third component can, for example, be inserted into the first component from a side opposite the second component. The third component can, for example, snap or hook into the second component or press against it, so that the second and third components mutually secure each other against unintentional disassembly from the first component. Alternatively or additionally, the third component can be wedged or screwed to the second component.

[0024] According to one embodiment, the relative movement of the two components is a rotation about a common central axis, wherein the third component is designed to prevent movement of the first component relative to the second component in a direction parallel to the central axis. This prevents unintentional disassembly of the second component from the first component.

[0025] According to one embodiment, the first component has a chamfer and the third component has a ramp that matches the chamfer. This combination of chamfer and ramp simplifies the assembly of the third component onto the first and second components. The chamfer and ramp can, for example, center the third component relative to the first and second components. Furthermore, the chamfer and ramp allow the third component to be positioned flush with the first component, thus reducing the space required for supporting the tendon.

[0026] According to one embodiment, the second component has at least one second connecting element, and the third component has at least one third connecting element. The connecting elements are designed to snap, hook, wedge, or screw the third component to the second component. This prevents unintentional movement of the second and third components relative to each other, as well as unintentional movement of the second and third components relative to the first component. Furthermore, it prevents unintentional disassembly of the components from one another. The at least one second connecting element can, for example, be a notch in which the at least one third connecting element snaps into place. The at least one third connecting element can, for example, be a locking hook.Alternatively or additionally, the third component and the second component can have a thread to allow the third component to be screwed to the second component.

[0027] In one specific embodiment, the third component has, for example, five third connecting elements arranged evenly around a central axis, designed to engage with a second connecting element of the second component. In the present embodiment, the third connecting elements are locking hooks and the second connecting element is a notch. The locking hooks can, for example, extend in the direction of the central axis and have a projection in a direction perpendicular to the central axis. This projection can be designed to engage with the notch and thus prevent unintentional disassembly of the device. In one embodiment, the connecting elements can press against the inner diameter of the second component. The connecting elements do not prevent intentional disassembly.The connection between the connecting elements can be released by applying sufficient force.

[0028] According to one embodiment, the second and third components are attached to each other in such a way that non-destructive disassembly is no longer possible. This allows the two components to be fastened together with a higher force, thus further reducing the risk of unintentional disassembly.

[0029] The invention is explained in more detail below with reference to exemplary embodiments and accompanying figures. The figures are schematic and not to scale. Neither absolute nor relative dimensions can be derived from them. Identical or equivalent components are designated with the same reference numerals in the various figures. Fig. Figures 1 to 3 show a schematic representation of the device in its assembled state. Fig. Figures 4 to 7 show a schematic representation of the first component. Fig. Figures 8 to 11 show a schematic representation of the second component. Fig. Figures 12 to 14 show a schematic representation of the third component.

[0030] The Fig. Figures 1 to 3 show a schematic representation of the device in its assembled state. Fig. Figure 1 shows an isometric view, Fig. 2 a side view and Fig. 3 a cross-sectional view.

[0031] The device comprises a first component 1, a second component 2, and a third component 3. All three components 1, 2, 3 are essentially rotationally symmetrical about a common central axis ZA. The Fig. The device shown in Figures 1 to 3 has a coil shape.

[0032] The first component 1 has a first fastening element 10, a first limiting element 11, a bearing surface 12, a first contact surface 13 and an insertion chamfer 14.

[0033] The second component 2 has a second fastening element 20, a second limiting element 21, a notch 22 and a second contact surface 23.

[0034] The third component 3 has an insertion ramp 30 and locking hooks 31.

[0035] The two fastening elements 10, 20 are designed to each receive one end of a bowstring. The bowstring is wound around the device so that it rests on the support surface 12. The first component 1 and the second component 2 are connected in such a way that they are movable relative to each other. For example, the first component 1 can be rotated in a first direction R1 about the central axis ZA, while the second component 2 is held in position. This movement changes the relative position of the two fastening elements 10, 20 such that a bowstring, received by the two fastening elements 10, 20 and wound around the support surface 12, can be tensioned. The bowstring could, for example, be the string of a sports bow.

[0036] Components 1, 2, and 3 can, for example, be inserted into one another along the central axis ZA. For this purpose, the second component 2 is inserted into the first component 1 from one side along the central axis ZA. After insertion, the first contact surface 13 of the first component 1 rests against the second contact surface 23 of the second component 2. The third component 3 is inserted into the first component 1 from the side opposite the second component 2 along the central axis ZA. The third component 3 is centered by means of the insertion chamfer 14 of the first component 1 and the insertion ramp 30 of the third component. The locking hooks 31 of the third component 3 engage with the notch 22 of the second component 2 when installed, thus securing the second component 2 and the third component 3 to each other and preventing unintentional separation from the first component 1.The insertion chamfer 14 and the insertion ramp 30 also ensure that the third component 3 does not protrude beyond the first component 1 in a direction parallel to the central axis ZA. When the first component 1 moves relative to the second component 2, the third component 3 can move along with either component 1 or 2.

[0037] The two fastening elements 10, 20 are integrated into the respective limiting elements 11, 21. For this purpose, the fastening elements 10, 20 are recessed into the respective limiting elements 11, 21. The limiting elements 11, 21 have corresponding recesses to facilitate improved retention of the tendon. The limiting elements 11, 21 extend in a direction perpendicular to the support surface 12 and prevent the tendon from slipping off the support surface 12 in a direction parallel to the support surface.

[0038] The pretension of the tendon, which is generated by the relative movement of the two fastening elements 10, 20 to each other, also prevents the tendon from slipping off the support surface 12 in a direction perpendicular to the support surface 12, since the pretension of the tendon presses the tendon against the support surface.

[0039] The radius of the support surface 12 is chosen such that a string stretched on the device can be stored without kinking and with sufficiently low curvature so that the string is not damaged.

[0040] The contact surfaces 13, 23 can have a surface profile designed to prevent unintentional movement of the first component 1 relative to the second component 2. The two contact surfaces 13, 23 are positioned such that the surface profile between them generates sufficient friction to prevent unintentional relative movement. By applying a corresponding force, the first component 1 can be intentionally moved relative to the second component 2. This allows, for example, the deliberate tightening or loosening of the bowstring tension, while preventing unintentional tightening or loosening of the bowstring tension.

[0041] The three components 1, 2, 3 have a ring shape, meaning they have a cavity around the central axis ZA. This allows for a reduction in the weight of the device and improved storage options, for example, on a hook on a wall.

[0042] Since the first direction R1 is a direction around the central axis ZA, the first direction R1 points in Fig. 3 once in the direction of the viewer (in Fig. 3 to the right of the central axis ZA) and once away from the viewer (in Fig. 3 to the left of the central axis ZA).

Fig. Figure 5 shows a detailed view of the first contact surface 13 at the location marked by the reference symbol B. Fig. 4. Fig. 6 shows a second side view and Fig. Figure 7 shows a cross-sectional view along line AA. Fig. 4.

[0044] The first component 1 has a first fastening element 10, a first limiting element 11, a bearing surface 12, a first contact surface 13, and an insertion chamfer 14. The mode of operation of the respective components is already described in relation to the Fig. 1 to 3 described and also apply, unless otherwise stated, to the Fig. 4 to 7.

[0045] In particular, the Fig. 4 to 7 the corrugated surface profile of the first contact surface 13. This surface profile prevents unintentional movement of the first component 1 relative to the second component 2 and allows relative movement between the first component 1 and the second component 2 with appropriate force application.

The mode of operation of the respective components is already described in relation to the Fig. 1 to 3 described and also apply, unless otherwise stated, to the Fig. 8 to 11.

[0048] In particular, the Fig. 8 to 11 the corrugated surface profile of the second contact surface 23. This surface profile prevents unintentional movement of the first component 1 relative to the second component 2 and allows relative movement between the first component 1 and the second component 2 with appropriate force application. This effect is particularly strong in combination with the corrugated surface profile of the first contact surface 13.
