Description

[0001] This application is a divisional application of patent application No. 201880014635.3 (International Application No. PCT / EP2018 / 054968), filed on February 28, 2018, entitled "Lock-in Device with Winding Element". Technical Field

[0002] This invention relates to a locking device. Background Technology

[0003] This locking device includes a first locking element and a second locking element, which are positioned close to each other along the closing direction, remain close to each other in the closed position, and can be released from each other in order to open the locking device.

[0004] Such locking devices are commonly used to connect two components to each other. For example, such locking devices can be provided as locking mechanisms for containers, such as bags or backpacks. However, such locking devices can also be used, for example, as locking elements for shoes, such as athletic shoes. Very generally, locking devices can be used to connect two arbitrary components in a load-bearing manner.

[0005] It is desirable that such a locking device can not only be used to loosely connect two components to each other, but also to fasten them. For example, in the case of a locking mechanism for a backpack or for a shoe, it is desirable to both place the components close to each other and, on the other hand, fasten them together.

[0006] A fastening mechanism having a traction element that can be wound onto a winding element is described, for example, in WO 2015 / 006616A1. Summary of the Invention

[0007] The purpose of this invention is to provide a locking device that, on the one hand, allows components to be loosely connected to each other, and on the other hand, also allows the components to be tightly fastened to each other.

[0008] The objective is achieved through a subject matter having the features of embodiments of the present invention.

[0009] Accordingly, the second locking member has a winding element on which a traction element may be disposed and the winding element may be twisted relative to the first locking member for winding the traction element onto the winding element in the winding direction.

[0010] By means of the proposed locking device, a locking mechanism and a fastening mechanism for releasably connecting two components to each other are combined. On one hand, the locking device has two locking members that can be positioned close to each other along the closing direction and held close to each other in the closed position, such that the components associated with the locking members are connected to each other via the locking members and their holding, and the components can be released from each other by separating the locking members. On the other hand, the second locking member has a winding element on which a traction element can be provided. The winding element can, for example, have the shape of a cylindrical roller and carry a winding groove in which the traction element can be accommodated. Thus, the traction element can be wound and tightened by twisting the winding element.

[0011] While the first locking element can be disposed on the first component, the second locking element can be connected to the second component via a traction element, wherein the first and second components can be secured relative to each other by winding the traction element onto a winding element.

[0012] The traction element can be, for example, a flexible element suitable only for transmitting traction force. The traction element can be, for example, a rope, belt, cord, chain, or (conductive) cable.

[0013] The traction element can be fixed to the winding element by means of its two ends, such that the traction element can be wound onto the winding element by twisting the winding element. It is also conceivable and feasible, however, that only one end of the traction element is fixed to the winding element, so that only one end of the winding element is wound by twisting the winding element. It is also conceivable and feasible, that an internal section of the traction element is disposed on the winding element, so that the traction element is wound by twisting the winding element. Furthermore, it is conceivable that multiple different traction elements are disposed on the winding element and can be wound via the winding element.

[0014] The winding element can be twisted relative to the first locking member along the winding direction to wind the traction element. Preferably, the winding direction is oriented about the closing direction, such that the winding element can be twisted relative to the first locking member about the closing direction. Thus, the locking members can be positioned close to each other along the closing direction, and the winding element can be twisted about the closing direction to fasten the components associated with the locking members together.

[0015] In one design, the winding element is twistable relative to the first locking member in the closed position. Preferably, the winding element is twistable relative to the first locking member in the winding direction in the closed position, but not in the opposite direction. This allows the traction element to be wound onto the winding element when the locking members are positioned close together. After the traction element is wound onto the winding element, the winding element remains in its adopted position. Reverse movement opposite to the winding direction for unwinding the traction element is prevented.

[0016] In another design, it can be proposed that, in contrast, when the locking elements are placed close together, the twisting of the winding element relative to the first locking element is no longer possible. Thus, in this case, when the locking elements are placed close together, torsional movements along the winding direction and in the opposite direction to the winding direction are blocked.

[0017] In one design, the winding element has a toothed mechanism that engages with the toothed mechanism of a first locking element in the closed position. This toothed mechanism can, for example, be formed by a serrated toothed portion that wraps around the winding direction.

[0018] However, such a toothed mechanism can also be formed by a single toothed element, which does not form a continuous toothed portion.

[0019] This toothed mechanism provides a unidirectional motion (Freilauf) that allows the winding element to twist relative to the first locking member in the winding direction when the locking elements are positioned close together and in a closed position, while blocking movement in the opposite direction. As the winding element twists relative to the first locking member, the toothed mechanism of the winding element slides on the toothed mechanism of the first locking member, enabling locking movement of the winding element relative to the first locking member in the winding direction. Under a load opposite to the winding direction, the toothed elements of the toothed mechanism engage with each other, blocking movement and holding the winding element in its proper position.

[0020] The toothed mechanisms can, for example, engage with each other in the axial direction. When the winding element is twisted relative to the first locking member in the winding direction, the toothed mechanisms slide up and down overlapping, for example, by sliding the serrated toothed elements onto each other. If the first and second locking members are torsionally supported relative to each other and axially guided relative to each other, this may be accompanied by a (slight) axial movement of the first locking member relative to the second locking member.

[0021] Alternatively, at least one toothed mechanism may have at least one toothed element that can be pressed to one side transversely to the winding direction when the winding element is twisted along the winding direction. Thus, in this case, no axial movement between the locking members is caused, but rather, when the winding element is twisted relative to the first locking member along the winding direction, the toothed element of one of the locking mechanisms is pressed to one side. This can be particularly useful when the first and second locking members are mechanically locked together in the closing direction and therefore cannot move axially relative to each other.

[0022] In general, the first and second locking members are mechanically locked together in the closed position, in opposition to the closing direction, to maintain the locking members. For this purpose, one of the locking members may, for example, have a locking mechanism with at least one movable locking element that engages in the locking engagement of the other locking member in the locked position, thereby holding the locking members together in opposition to the closing direction. Thus, when the locking members are positioned close together, a mechanical locking is formed between the locking members via the locking mechanism. The locking mechanism holds the locking members together against loads opposite to the closing direction, preventing them from being removed without releasing the locking mechanism.

[0023] Preferably, when the locking elements are placed close together, the locking mechanism automatically reaches the locked position. Thus, when the locking elements are placed close together, they automatically lock together, ensuring that the locking elements remain in the closed position. Here, although the winding element is locked, it can rotate relative to the first locking element in the winding direction if necessary, so that the traction element can be wound onto the winding element when the locking elements are placed close together.

[0024] The locking mechanism may have one or more locking elements. The locking elements are, for example, spring-preloaded toward their locked position, such that the locking elements preferably automatically engage with the associated locking engagement of another locking element when the locking members are positioned close to each other.

[0025] To loosen the locking between the locking elements and to separate them to open the locking device, the locking mechanism preferably has an actuating element that can be operated to disengage at least one locking element from the locking engagement. The actuating element can be operated, for example, by pressing and has, for example, an impact element configured to impact a pre-tensioning element when the actuating element is operated, thereby adjusting at least one locking element, which pre-tensions at least one locking element in the direction of the locking position. The pre-tensioning element can be formed, for example, by a spring coil, on which the locking element is formed on one side and the impact element on the other. By causing the impact element of the actuating element to impact the impact element of the pre-tensioning element, the annular pre-tensioning element deforms, causing the locking element to move and disengage from the locking engagement of the other locking element.

[0026] The winding element can be integrally formed with the engaging element of the second locking member, such that the second locking member, together with its winding element, can move as a whole. Thus, by twisting the second locking member along with the winding element thereon, the traction element can be wound onto the winding element so that the traction element is properly secured. In this case, the locking members are, for example, rotatably supported against each other, wherein the cylindrical flange of one locking member engages with and is thereby supported in the other locking member.

[0027] The cylindrical flange can be guided on another locking element, so that the locking elements can be axially adjusted relative to each other and, for example, can be axially positioned close to each other along the closing direction.

[0028] In one design, the second locking member has a housing element disposed on the first locking member in the closed position, and a winding element is rotatably supported on the housing element. In this case, the housing element can, for example, be torsionally mounted on the first locking member and, for example, fixedly held on the first locking member in the closed position of the locking device. The winding element is rotatable relative to the housing element, such that the traction element can be wound onto the winding element in the winding direction by twisting the winding element, thereby securing it.

[0029] In one design, the second locking member has a blocking assembly that, in a blocking state, blocks the winding element relative to the housing element, allowing the winding element to twist relative to the housing element along the winding direction, but not in the opposite direction to the winding direction.

[0030] Thus, the blocking assembly is used to allow the winding element to twist relative to the housing element in the winding direction, and to prevent the winding element from rotating back in the opposite direction to the winding direction. Thus, the winding element can be twisted in the winding direction according to a unidirectional motion form via the blocking assembly in order to wind the traction element, wherein after twisting, the winding element remains in its occupied position and can absorb the traction force acting on the traction element via the blocking assembly.

[0031] Preferably, the blocking assembly can be unlocked from the blocking state. This allows the winding element to be released, enabling it to twist relative to the housing element in the opposite direction to the winding direction, thereby unwinding the traction element from the winding element. Thus, by unlocking the blocking assembly, the traction element can be loosened by unwinding it from the winding element.

[0032] In one design, the blocking assembly can be proposed to automatically unlock when the locking device is opened. If the locking members are separated from each other and the housing element of the second locking member is removed from the first locking member, the blocking assembly automatically reaches its unlocked state, thereby releasing the winding element and allowing the traction element to unwind from the winding element.

[0033] In one design, the blocking assembly has an operating element, which may be configured as a handle and rotatably mounted on the housing element. The winding element can be twisted via the operating element, wherein this operating element is effectively connected to or disconnected from the winding element, depending on the state of the blocking assembly.

[0034] The operating element and the housing element can be effectively connected to each other, for example, via a one-way mechanism. This one-way mechanism allows the operating element to be twisted relative to the housing element in the winding direction, while preventing twisting in the opposite direction. If the operating element is effectively connected to the winding element, then the winding element can be twisted in the winding direction via the operating element, without twisting in the opposite direction.

[0035] In one design, the one-way mechanism has a toothed portion on the housing element or the operating element and at least one adjustable blocking element, for example in the form of a pawl, on which additional elements are respectively provided. The toothed portion may, for example, be formed as an internal toothed portion on a cylindrical flange of the housing element, wherein in this case, one or more movable (e.g., pivotable) blocking elements are provided on the operating element. When the operating element is twisted in the winding direction, the blocking element slides on the toothed portion, making twisting of the operating element in the winding direction possible; however, reverse twisting opposite to the winding direction is blocked due to the engagement of the blocking element with the toothed portion, thus preventing the operating element from twisting relative to the housing element opposite to the winding direction.

[0036] It is conceivable and possible that the operating element can be unlocked, for example, by axial adjustment relative to the housing element, in order to disengage the blocking element from the toothed portion.

[0037] To establish an effective connection between the operating element and the winding element, the operating element may, for example, have a toothed mechanism, while the winding element carries a second toothed mechanism. The toothed mechanisms may, for example, be sawtooth-shaped, wherein engagement causes the winding element to be driven when the operating element twists in the winding direction, and consequently twists relative to the housing element in the same winding direction. Under a load caused by a traction force introduced via a traction element at the winding element, the winding element is held in position relative to the housing element via the operating element when the toothed mechanisms are engaged, preventing the traction element from unwinding from the winding element, wherein the traction force creates a torque load opposite to the winding direction.

[0038] To release the winding element and unwind the traction element, the operating element can be axially adjusted relative to the housing element, such that the toothed mechanism disengages on the operating element on one side and on the winding element on the other side, thus the winding element is no longer held in position by the operating element. Consequently, the winding element can be twisted relative to the housing element in the opposite direction of winding, thereby unwinding the traction element from the winding element.

[0039] The housing element is held on the first locking member when the locking members are positioned close to each other. The housing element can, in the closed position, be mechanically and permanently connected to the first locking member, for example, by locking the housing element to the first locking member.

[0040] In one design, the first locking member may, for example, have at least one first undercut element, while the housing element of the second locking member includes at least one second undercut element. When the locking members are positioned close together, the undercut elements engage with each other, such that the locking members are held in a closed position in opposition to the closing direction.

[0041] The undercutting elements are rigidly formed, for example, on the base of the first locking member and on the housing element of the second locking member. After the locking members are positioned close to each other in the closing direction, the undercutting elements engage with each other transversely to the closing direction in the engagement direction, such that the undercutting elements engage with each other and establish a connection between the locking members that can withstand loads opposite to the closing direction.

[0042] In one design, the first locking member has at least two first undercut elements, which are arranged laterally and offset from each other on the base of the first locking member in the closing direction. Similarly, the housing element of the second locking member may have at least two second undercut elements, which are arranged laterally and offset from each other on the housing element of the second locking member in the closing direction, and are associated with and engaged with the first undercut elements of the first locking member in the closed position. By providing multiple undercut elements on each locking member, a high-strength, mechanically load-bearing connection between the locking members can be achieved in the closed position.

[0043] For example, the first undercut element of the first locking member is diagonally opposite the axis of rotation of the winding element, and similarly, the second undercut element of the housing element of the second locking member is diagonally opposite the axis of rotation of the winding element. Thus, by providing undercut elements on both sides of the winding element, the force acting between the locking members in the closed position can be absorbed and discharged extremely effectively.

[0044] The undercut elements can be, for example, bow-shaped or V-shaped. Here, bow-shaped is understood as any curved shape, which may, for example, have sections with straight extensions and thus be curved only in some sections. A V-shape can be formed, for example, by two undercut elements arranged at an angle to each other to form a V-shape.

[0045] In one design, one of the locking elements has a locking element for locking the engagement between at least one first undercut element and at least one second undercut element in the closed position of the locking element. This locking element may, for example, be provided on the first locking element and function to lock the locking elements in the closed position, thereby ensuring the engagement between the undercut elements and preventing the undercut elements from disengaging from each other, particularly in the opposite direction of engagement.

[0046] The locking element, for example, can be a member facing another locking member in the locked position, such that the undercutting element is also kept engaged. If the locking member is subjected to a load opposite to the engagement direction, the locking element prevents the undercutting elements from disengaging from each other, thus also ensuring that the locking members remain close together.

[0047] Preferably, the locking element is spring-preloaded in the direction of its locked position. When the locking device is closed, the locking element thereby automatically reaches its locked position, such that the locking members are locked in their interconnection in the closed position.

[0048] To open, for example, the locking element can be adjusted to disengage from its locked position. By, for example, manually applying force to the locking element, the locking of the locking elements relative to each other can be released, so that the locking elements can be released from each other by separating the undercut elements.

[0049] Alternatively, it can be proposed to adjust the member of the locking element in the locked position toward another locking member, thereby releasing the locking effect of the locking element. If the locking element is, for example, located on the first locking member, then the member may relate to the operating element of the second locking member, which may be axially adjusted toward the housing element, thereby disengaging the effective connection between the operating element and the winding element on the one hand, and disengaging the operating element from its locking opposition with respect to the locking element on the other hand.

[0050] The aforementioned type of locking device can be configured as a purely mechanical locking device, wherein the locking elements are arranged close to each other and mechanically held close to each other in the closed position. Through this mechanical holding, shear forces can be absorbed in the plane transverse to the closing direction, and, if necessary, forces opposite to the closing direction can also be absorbed when the locking elements are mechanically locked together.

[0051] However, in an advantageous design, the locking device is magnetically configured. For this purpose, the first and second locking members each have at least one magnetic element, which, when the locking members are placed close together, magnetically attract each other to magnetically assist in closing the locking device.

[0052] The magnetic element here can be a permanent magnet or a magnetic armature, for example, formed of a ferromagnetic material. For example, one of the locking elements has a permanent magnet, which interacts with the magnetic armature of the other locking element in a magnetically attractive manner. However, it is also conceivable to have a device in which the two locking elements each have a permanent magnet or multiple permanent magnets, which, when the locking elements are placed close together, are positioned with opposite magnetic poles facing each other and thus aided by magnetic attraction.

[0053] The operation of the operating element can be performed manually by twisting it. However, another possible design is to use a motor to drive the operating element. This motor could, for example, be fixedly mounted on an assembly connected to the first locking member and, when the locking device is in its closed position, engage with the toothed portion of the operating element, for example, via a suitable transmission element, such as a worm gear. Thus, the operating element can be twisted via the motor.

[0054] An alternative that can be considered and is possible is to electrically drive the toothed mechanism of the first locking member so as to twist the winding element by twisting the toothed mechanism of the first locking member.

[0055] In one design, one or more electrical contact elements may be provided on the first locking element and the second locking element respectively, so that electrical contact is formed between the locking elements when the locking device is closed.

[0056] In another design, the locking device may have a winch output element, for example in the form of an eyelet, which is located on the second locking member and may be configured as an additional component for the winding element and the operating element. The winch output element may, for example, be freely rotatable relative to the winding element and / or the operating element and guide the traction element with respect to the winding element, such that the traction element extends into the winding element in a defined manner. This prevents the traction element from uncontrollably unwinding from the winding element and, in particular, prevents the traction element from tangling during unwinding.

[0057] The locking device described herein achieves a releasable connection between the locking element and the locking member, which can be combined with the tightening possibilities of the traction element. This, for example, allows the traction element to be pre-tensioned with tension when the locking member is open, so that the locking device can subsequently be closed and the traction element can be wound and re-tightened by a twisting winding element in the closed position of the locking device. For example, in the case of shoes, the traction element (depending on the type of shoelace) can be manually pre-tensioned with tension at the traction element when the locking device is open and then re-tightened when the locking device is closed.

[0058] Furthermore, the separation of the locking elements allows the traction element, connected to the winding element, to be arranged around the article so that one component can be secured to another component by means of the locking device. Therefore, the traction element can be arranged, for example, around a support post or frame, such as a bicycle frame, when the locking device is open, so that the locking device can be subsequently closed and the traction element tightened, thus securing one component to the support post or frame in this way.

[0059] The locking device of the type described herein can be used in entirely different ways. Therefore, the locking device of the type described herein can be used in bags or other containers such as backpacks, boxes or containers, in shoes (especially athletic shoes such as hiking shoes, snow boots, etc.), in helmets, especially sports helmets, or in medical assistive devices such as, for example, medical support tracks.

[0060] For example, a strap on a bag or pocket can be fastened via a locking device of the type described herein. The straps or belts of a backpack or purse can be closed and fastened via such a locking device. Furthermore, such a locking device can be used on a cable reel used for winding electrical wires, such as, for example, headphones or charging cables.

[0061] The helmet can be secured with a locking device of the type described herein, or items such as goggles (e.g., ski goggles) can be attached to the helmet.

[0062] This locking device can also be used to load and secure accessories or bags to vehicles (bicycles, cars, trucks, boats, airplanes, etc.) or vehicles, for example as a fastening device on bicycle luggage carriers.

[0063] Specifically, such locking devices can be used, for example, on a fastenerable bracket around a bicycle frame to secure components, such as water bottles or containers, to the bicycle frame.

[0064] In addition, this locking device can be used to fasten any type of cover and fabric, such as for fastening tent covers or sunshades.

[0065] Military applications are also possible and warrant consideration. Therefore, the locking device could be used to secure and load weapons and ammunition.

[0066] The type of locking device described can also be used in hemostatic dressing systems to bandage severely bleeding wounds of patients. Attached Figure Description

[0223] Figure 1A , 1B Figures 10A to 10D show an embodiment of a locking device 1, which has a first locking member 2 and a second locking member 3. The locking members 2 and 3 can be arranged close to each other along the closing direction X and held close to each other in the closed position, such that a mechanically fixed connection between the locking members 2 and 3 is achieved in the closed position.

[0224] For example, especially from the basis Figure 2A and 2B As can be seen in the exploded view, the first locking member 2 has a base 20 on which two rigid undercut elements 21 and 22 are formed, each having an arcuate configuration. A locking element 24 is also provided on the base 20, which is pivotally supported between the sidewall portions 200 of the base 20 via a shaft element 240 and spring-preloaded to a locked position via a spring element 241, as will be further explained below.

[0225] The second locking member 3 has a housing element 30 on which two rigid undercut elements 31 and 32 are provided. These two undercut elements are associated with the undercut elements 21 and 22 of the first locking member 2 and mechanically engage with the undercut elements 21 and 22 of the first locking member in the closed position.

[0226] A cylindrical flange 300 is formed on the housing element 30, which surrounds an inner cavity 301 in which the winding element 35 is rotatably supported around a support top 303. An operating element 34, in the form of a gripping element, engages with the inner cavity 301 via a body 340 and penetrates the opening 304 of the support top 303 via a bolt 342, and is connected to a locking element 36 within the support top 303 (see, for example, according to...). Figure 3C (Cross-sectional view).

[0227] A toothed portion 302 is formed circumferentially from the inside on the cylindrical flange 300. This toothed portion interacts with a blocking element 343, which is preloaded via a spring element 344 and movably supported within the body portion 340 by the operating element 34 (see, for example, according to...). Figure 3C (Cross-sectional view). As should be further explained below, the toothed portion 302 together with the blocking element 343 forms a one-way mechanism (Freilauf), which enables the operating element 34 to twist relative to the housing element 30 in the winding direction V, while blocking the opposite rotational movement in the opposite direction of the winding direction V.

[0228] The operating element 34 has a toothed portion 342 on the end side of the body 340 facing the winding element 35. This toothed portion is associated with the toothed portion 351 of the winding element 35, and the operating element 34 can be effectively connected to the winding element 35 via the toothed portion 342. If an effective connection is established between the operating element 34 and the winding element 35, the winding element 35 can be twisted by twisting the operating element 34, thereby traction element 4 (see...) Figure 1B The traction element 4, which is introduced into the inner cavity 301 via the opening 305, can be wound into the groove 353 at the winding body 350 of the winding element 35 so that the traction element 4 can be wound onto the winding body 350.

[0229] The first locking element 2 has a first magnetic element 23 fixed on the base 20. The second locking element 3 has a second magnetic element 33 disposed on the housing element 30 and magnetically interacting with the first magnetic element 23 of the first locking element 2. The magnetic elements 23 and 33 can each be made of permanent magnets and have opposite magnetic poles, thus interacting magnetically when the locking elements 2 and 3 are in place. Alternatively, one of the magnetic elements 23 and 33 can be made of permanent magnets, while the other magnetic element 33 and 23 can be made of a magnetic armature, for example, formed of a ferromagnetic material, thus creating a magnetic attraction between the magnetic elements 23 and 33.

[0230] Figures 3A-3D Figures 10A-10D show the locking device 1 in different positions.

[0231] Figures 3A-3D The locking device 1 is shown in the open position when the locking elements 2 and 3 are separated from each other. (As shown from...) Figure 3CAs can be seen in the cross-sectional view, in the position shown, the operating element 34 engages with the toothed portion 351 of the associated winding element 35 via its toothed portion 341, thus forming an effective connection between the operating element 34 and the winding element 35. In the axial position, the operating element 34 (axially adjustable relative to the housing element 30) is held within the support top 303 of the housing element 30 by locking the locking protrusion 360 of the locking element 36 into the locking groove 305.

[0232] If the operating element 34 twists relative to the housing element 30 along the winding direction V, then due to the effective connection between the operating element 34 and the winding element 35, the winding element 35 twists together, causing the traction element 4 provided on the winding element 35 to wind onto the winding body 350 of the winding element 35. The twisting of the operating element 34 is possible here because the locking element 343 slides on the internal toothed portion 302 on the cylindrical flange 300 of the housing element 30 when the operating element 34 twists along the winding direction V, thus not obstructing the twisting of the operating element 34 along the winding direction V.

[0233] After the twist, the operating element 34 and the winding element 35 effectively connected thereto remain in their occupied positions. The traction force acting on the traction element 4 can be introduced into the housing element 30 via the winding element 35 and the operating element 34 through the blocking element 343, which acts as a blocking element from now on, and is absorbed there.

[0234] To relieve the stress at the traction element 4, the operating element 34 is used, as shown in... Figures 4A-4D As shown, it is axially adjusted relative to the support top 303 of the housing element 30, thereby, as from Figure 4C As can be seen, the locking element 360 engages with the upper locking groove 305 within the support top 303, thereby locking the operating element 34 relative to the housing element 30 in an axially upward position. The axial movement of the operating element 34 releases the effective connection between the teeth 341 and 351 of the operating element 34 and the winding element 35, causing the operating element 34 and the winding element 35 to disengage. Thus, the winding element 35 is no longer obstructed and can move relative to the housing element 30 in the opposite direction to the winding direction V, allowing the traction element 4 to unwind from the winding element 35.

[0235] By axially moving the operating element 34, the blocking element 343 at the body 340 is also axially adjusted relative to the internal toothed portion 302 at the cylindrical flange 300 of the housing element 30, thereby releasing the blocking effect between the operating element 34 and the housing element 30. As a result, the operating element 34 can be freely twisted relative to the housing element 30 when necessary (also opposite to the winding direction V).

[0236] Figures 5A-5D Figures 6A-6D show the locking device 1 when the locking elements 2 and 3 are placed close to each other. When the locking elements 2 and 3 are placed close to each other, the undercut elements 21, 22, 31, 32 on the base 20 of the first locking element 2 and on the housing element 30 of the second locking element 3 collide with each other and are laterally offset relative to each other, so that the undercut elements 21, 22, 31, 32 can move close to each other in the closing direction X to form an engagement with each other.

[0237] The locking elements 2 and 3 are magnetically assisted by the magnetic elements 23 and 33, so that the installation can be carried out as automatically as possible.

[0238] If the undercut elements 21, 22, 31, 32 move close to each other and the base 20 of the first locking member 2 and the housing element 30 of the second locking member 3 come into contact with each other, as this occurs... Figures 7A to 7D As shown, magnetic elements 23 and 33 are offset relative to each other. Therefore, a lateral force acts between magnetic elements 23 and 33, which causes the undercut elements 21, 22, 31, and 32 to engage with each other along the engagement direction E, as shown in... Figures 8A to 8D As shown in the diagram. Therefore, locking elements 2 and 3 achieve [the desired effect]. Figures 8A to 8D The closed positions shown in the diagram are mechanically connected to each other and held close to each other in the closed positions.

[0239] For example, especially from Figures 7A to 7D As can be seen, the operating element 34 acts on the locking element 24 when the locking elements 2 and 3 are placed close together, and the operating element deflects against the spring preload of the spring element 241 (see especially according to...). Figure 7C (Cross-sectional view). If the undercut elements 21, 22, 31, 32 engage with each other, then the locking element 24 moves back to its initial position due to the spring preload of the spring element 241 and reaches a position relative to the circumferential edge of the operating element 34, such that it also blocks the movement of the second locking member 3 relative to the first locking member 2 in the opening direction Y (opposite to the engagement direction E) and keeps the undercut elements 21, 22, 31, 32 engaged with each other in a form fit.

[0240] In the closed position, the winding element 35 can be twisted by turning the operating element 34 along the winding direction V, thereby winding the traction element 4 onto the winding element 35. As a result, the traction element 4 can be tightened, so that the first component connected to the first locking member 2 and the second component connected to the second locking member 3 via the traction element 4 can be tightly fixed to each other under traction force.

[0241] If the locking device 1 is opened, then the operating element 34 can be adjusted axially relative to the housing element 30 of the second locking member 3 along the releasing direction L, as is the case in Figures 9A-9D As shown in the figure. Thus, the operating element 34 is disengaged from the winding element 35 (the toothed portions 341 and 351 are separated from each other), so that the winding element 35 can freely twist relative to the housing element 30 and, in particular, can move in the opposite direction to the winding direction V, so as to unwind the traction element 4 from the winding element 35.

[0242] By moving the operating element 34 axially in the releasing direction L, the operating element 34 also disengages from its opposition to the locking element 24. The undercutting elements 21, 22, 31, and 32 can thus disengage from each other, allowing the locking elements 2 and 3 to, as in... Figure 10A-10D As shown, they are separated from each other.

[0243] The locking elements 2 and 3 can also be separated when the traction element 4 is tightened, i.e. when the operating element 34 and the winding element 35 are effectively connected. To do this, the locking element 24 can be manually operated by pressing it downward against the spring preload 241, thereby releasing the locking element 24 from the opposite position locked to the operating element 34.

[0244] Figure 11A , 11B Figures 17A-17B show a second embodiment of the locking device 1, wherein the locking elements 2 and 3 can be along the closing direction X (see, for example, see...). Figure 13A They are placed close to each other and remain close to each other in the closed position.

[0245] According to Figure 13A and 13B As can be seen in the exploded view, the first locking member 2 has a base 20 on which a cylindrical flange 201 is formed. A toothed portion 25 surrounds the cylindrical flange 201, the teeth of which are serrated. A magnetic element 23 is also provided on the base 20.

[0246] The second locking element 3 has an operating element 34, and a winding element 35 is fixedly connected to the operating element, for example, in a one-piece manner. The winding element 35 has a groove 353 in which a traction element 4 can be accommodated for winding onto the winding element 35. A magnetic element 33 is fixed to the operating element 34, and the magnetic element magnetically attracts and interacts with the magnetic element 23 at the first locking element 2.

[0247] A toothed portion 351 is formed on the winding element 35 on the side facing the first locking member 2. When the locking members 2 and 3 are placed close together, the toothed portion 351 of the winding element 35 engages with the toothed portion 25 on the base 20 of the first locking member 2, as shown in... Figures 14A-14D As shown in the figure.

[0248] When the locking elements 2 and 3 are positioned close to each other, the cylindrical flange 301 engages with the operating element 34 and is rotatably and axially movable on the operating element 34.

[0249] The toothed portion 351 of the winding element 35 and the toothed portion 25 of the first locking member 2 are serrated. This enables, as in Figures 15A-15D As shown in 16A-16D, the second locking member 3, together with the winding element 35 and the operating element 34, moves relative to the first locking member 2 along the winding direction V, wherein the teeth of the toothed portions 25 and 351 slide on each other and move back and forth to each other, so that the locking members 2 and 3 are axially offset relative to each other. Thus, the toothed portions 25 and 351 have a one-way mechanism that enables the winding element 35 to be twisted along the winding direction V when the locking members 2 and 3 are placed close to each other, so as to tighten the traction element 4 provided on the winding element 35, while preventing movement in the opposite direction of the winding direction V, so that the traction element 4 will not unwind when the locking members 2 and 3 are placed close to each other.

[0250] Due to the magnetic interaction of the magnetic elements 23 and 33, the locking elements 2 and 3 are held close to each other and, after being twisted, always reach a position in which the toothed portions 25 and 351 are shaped to engage with each other.

[0251] To release the locking elements 2 and 3 from each other, they can be removed from each other in the opposite direction of the closing direction X. This also releases the interaction between the toothed portions 25 and 351, allowing the traction element 4 to unwind from the winding element 35.

[0252] According to Figure 11A , 11B In embodiments 17A-17D, the second locking element 3 and the winding element 35, which is fixedly connected to the operating element 34, are twisted together. This results in a very simple locking device 1.

[0253] According to Figure 11A , 11B In embodiments 17A-17D, the second locking member 3, in the closed position, is twistable relative to the first locking member 2 along the winding direction V. And... Figure 18A , 18B In the embodiment shown, the toothed portions 25 and 351 at the first locking member 2 and the second locking member 3 are configured such that when the locking members 2 and 3 are placed close together, it is impossible for the locking members 2 and 3 to twist relative to each other (in any direction), but they are blocked by the engagement of the toothed portions 25 and 251.

[0254] In this embodiment, the tightening of the traction element 4 by winding onto the winding element 35 is only possible before the locking members 2 and 3 are placed close together. Similarly, the traction element 4 can be loosened only when the locking members 2 and 3 are removed from each other.

[0255] exist Figure 19A , 19B In the embodiments shown in 26A-26D, the first locking member 2 has a base 20 on which a cylindrical flange 201 is formed, the cylindrical flange surrounding a toothed mechanism 25 having toothed elements 250 connected to each other via rings 251. In the assembled position, the toothed elements 250 extend radially outward through a gap 202 in the cylindrical flange 201 and can form an effective connection with the toothed portion 351 at the winding element 35 of the second locking member 3.

[0256] The second locking member 3 has an operating element 34, which is fixedly connected to the winding element 35. A locking mechanism 37 is provided on the operating element 34, which has a locking element 370. The locking element has a locking protrusion 371 connected via an annular pre-tightening element and can be operated via the operating element 375.

[0257] For example, from according to Figure 21C As seen in the cross-sectional view, the locking mechanism 37 is housed within the body 340 of the operating element 34 and protrudes radially from the body 340 with its locking protrusion 371. When the locking elements 2 and 3 are positioned close together, as shown in this... Figures 22A-22D As shown, the cylindrical flange 201 of the first locking member 2 is axially engaged with the operating element 34 and surrounds the body 340 of the operating element 34, such that as from Figures 23A-23D As seen in 24A-24D, the locking protrusion 371 is radially pressed inward to one side and finally, according to Figures 24A-24D In the closed position of the locking device 1, it engages with the locking engagement portion 203, which is in the form of an annular groove that surrounds the cylindrical flange 201 from the inside.

[0258] Thus, in the closed position, locking elements 2 and 3 are locked together, so that locking elements 2 and 3 are axially held in position relative to each other via locking mechanism 37.

[0259] When installing locking elements 2 and 3, the toothed portions 25 and 351, for example, from according to Figure 24B As can be seen in the partial cross-sectional view, they are engaged with each other. The operating element 34, together with the winding element 35, is movable relative to the first locking member 2 along the winding direction V, where, as from... Figures 25A-25DAs can be seen, the toothed element 250 is pressed into the cylindrical flange 201 radially inward by being squeezed to one side by the teeth of the toothed portion 351 of the winding element 35.

[0260] Therefore, the winding element 35 can be twisted along the winding direction V to wind the traction element 4. The twisting motion of the winding element 35 relative to the first locking member 2 in the opposite direction to the winding direction V is blocked by the engagement of the toothed element 250 on the side of the first locking member 2 and the toothed portion 351 on the side of the second locking member 3, making it impossible for the traction element 4 to unwind from the winding element 35.

[0261] When the winding element 35 is twisted relative to the first locking member 2, the first locking member 2 and the second locking member 3 remain axially fixed relative to each other due to the locking mechanism 37. The twisting of the winding element 35 can be achieved here by the radial compression of the toothed element 250 of the toothed portion 25 of the first locking member 2.

[0262] To release the locking elements 2 and 3 from each other, the user can manually press the operating element 375 at the operating element 34 (in Figure 26A (Operating direction D). Thus, the operating element 375, by means of an impact element 376 having an impact ramp formed thereon, impacts an inclined impact element 372 formed on an annular preload element 373, thereby deforming the preload element 373. Thus, as from... Figure 26C As can be seen, the locking protrusion 371 is pulled radially inward, thereby releasing the engagement between the locking element 371 and the locking engagement 203 at the cylindrical flange 201, and allowing the locking members 2 and 3 to be removed from each other axially opposite to the closing direction X.

[0263] According to Figure 19A , 19B In embodiments 26A-26D, each locking element 2, 3 also has magnetic elements 23, 33, which magnetically attract each other when the locking elements 2, 3 are placed, thereby assisting the locking elements 2, 3 in magnetically close-to-each other placement.

[0264] Figures 27A to 27D Another embodiment is shown, wherein the toothed portions 25, 351 acting between the first locking member 2 and the winding element 35 are similar to those described above. Figure 11A , 11B The embodiments described in 17A-17B are similarly configured such that reference should be made to the above description.

[0265] according to Figures 27A to 27DThe embodiment has a locking mechanism 37, which is disposed on the second locking member 3 and is used to lock the locking members 2 and 3 together in the closed position, such that the second locking member 3 is locked in the opposite direction of the closing direction X and thus is held in a form-fitting manner on the first locking member 2.

[0266] The use of this locking mechanism 37 enables a non-magnetic design for the locking device 1. In principle, this eliminates the need for magnetic elements in the locking mechanism 1. However, it is also possible and feasible to additionally use magnetic elements in the locking mechanism 37.

[0267] The locking mechanism 37 has an engaging element 38, which is axially movably received in a receiving cavity within an operating element 34 via an annular flange 381 and is spring-preloaded relative to the operating element 34 via a spring element 384 in the form of a helical spring. Diagonally opposite receiving openings 382 are formed at a cylindrical body 380 extending from the annular flange 381, in which a spherical locking element 385 is received for use in the closed position of the locking device 1. Figure 27D It is locked into the locking engagement portion 203, so that, as from this, Figure 27D As can be seen, in the closed position, a locking mechanism is formed between the engaging element 38, which engages with the opening of the cylindrical flange 201, and the cylindrical flange 201, thereby locking the locking members 2 and 3 to each other. The locking engagement portion is in the form of an annular groove surrounding the inner side of the cylindrical flange 201 of the first locking member 2.

[0268] Within the central opening 383 of the engaging element 38, the actuating element 39 is axially guided along the closing direction X. The actuating element 39 has a cylindrical configuration and is elastically supported on the first locking member 2 in the closed position via a spring element 394 inserted into the blind hole-shaped opening 393. When it is not yet operated relative to the engaging element 38, it abuts against the engaging element 38 in a limited distance via an annular flange 391 on the end side.

[0269] As from Figure 27D As can be seen, the operating element 39 has two diagonally opposite unlocking openings 392 on its outer circumferential surface. The unlocking openings are positioned at different axial heights with respect to the locking element 385 in the closed position, such that the locking element 385 abuts against the outer circumferential surface of the cylindrical body 390 of the operating element 39 and is also lockedly engaged with the locking engagement portion 203 on the inner side of the cylindrical flange 201.

[0270] In the closed position ( Figure 27DThe operating element 34 is pressed towards the first locking member 2 by the spring preload of the spring element 384, and the winding element 35 is pressed into contact with the toothed portion 25 of the first locking member 2 by the base surface 340 abutting against the annular flange 354 of the winding element 35. Thus, in the closed position, when engaged between the winding element 35 and the first locking member 2, the second locking member 3 is locked onto the first locking member 2.

[0271] If, in the closed position of the locking device 1, the operating element 34, and thus the winding element 35, twist together with the operating element 34 in the winding direction V, then the toothed portions 25, 351 slide over each other, causing a (slight) axial movement of the winding element 35 and thus the operating element 34. Because the engaging element 38 of the locking mechanism 37 is axially fixed relative to the cylindrical flange 201 of the first locking member 2 via the locking element 385, the axial displacement of the winding element 35 and the operating element 34 proceeds against the spring preload of the spring element 384.

[0272] After the operating element 34 and the winding element 35 have completed their twisting, the toothed portions 25 and 351 reconnect due to the spring preload of the spring element 384.

[0273] To release the locking elements 2 and 3 from each other, the user can press the operating element 39 into the engaging element 38 along the operating direction D. This causes the body 390 of the operating element 39 to axially adjust within the engaging element 38 along the closing direction X, so that the unlocking opening 392 reaches the same axial height as the locking element 385, allowing the locking element 385 to shift radially inward. In this way, the locking between the engaging element 38 and the cylindrical flange 201 is released, allowing the locking elements 2 and 3 to be removed from each other in the opposite direction to the closing direction X.

[0274] To reclose the locking device 1, the second locking member 3 can be repositioned onto the first locking member 2 along the closing direction X. This allows the engaging element 38 to engage with the opening of the cylindrical flange 201, and the locking element 385 to engage securely with the locking engagement portion 203, which is in the form of a groove surrounding the cylindrical flange 201. Consequently, the toothed portions 25 and 351 also mesh with each other, and the locking device 1 employs… Figure 27D The closed position is shown in the figure.

[0275] Figure 28 Showing relative to according to Figures 27A-27D The modified embodiment, which differs in appearance view from the embodiment according to Figures 27A-27D The embodiments are similar. According to... Figure 28In one embodiment, the locking mechanism 37 has an engaging element 38 on which a through hole 387 extending transversely to the closing direction X is formed. Two spherical locking elements 385 are disposed in the hole and pre-tensioned relative to each other via a spring element 386. When the locking members 2 and 3 are positioned close together, the engaging element 38 engages with the cylindrical flange 201, and the locking elements 385 are locked with locking engagement portions 203 on the inner side of the opening of the cylindrical flange 201. This can be achieved from... Figure 28 This can be seen from the text.

[0276] The locking mechanism is maintained in the closed position by the spring element 386 due to the spring preload. If the locking needs to be released, the second locking member 3 is removed from the first locking member 2 when sufficient force is applied, opposite to the closing direction X. This causes the locking element 385 to automatically move radially inward along the upper edge of the slotted locking engagement 203, thus disengaging from the locking engagement 203. Therefore, the locking between the locking members 2 and 3 can be released without special operation of the engaging element 38.

[0277] according to Figure 28 The embodiment is magnetically configured such that a magnetic element 23 is provided on the body portion 20 of the first locking member 2 and a magnetic element 33 is also provided on the body portion 380 of the engaging member 38, as shown in the embodiment. Figure 28 As can be seen in the cross-sectional view, locking elements 2 and 3 thus act magnetically together, which makes the installation of locking elements 2 and 3 easy.

[0278] However, according to Figure 28 The embodiments can also be constructed purely mechanically without magnetic components.

[0279] In the embodiments described above, the toothed mechanisms 25 and 351 are configured substantially differently on the sides of the first locking member 2 and the second locking member 3, so as to maintain the shape fit between the locking members 2 and 3 (at least capable of withstanding up to a certain limit torque) in the closed position.

[0280] Figure 29A , 29B 33A and 33B show different embodiments of the toothed mechanisms 25 and 351, which differ in the geometry of their teeth and can be used in locking devices 1 of the type described herein.

[0281] Therefore, according to Figure 29A , 29BIn this embodiment, each tooth of the toothed mechanism 25, 351 has a tooth flank extending at an angle to the closing direction X in the form of an impact ramp 253 and a tooth flank 254 extending approximately vertically, on which a protruding element 252 is formed, projecting along the winding direction V. When the load along the load direction B is opposite to the winding direction V, the protruding elements 252 of the teeth of the toothed mechanisms 25, 351 engage with each other, thereby blocking the movement of the toothed mechanisms 25, 351 along the load direction B (opposite to the winding direction V). Thus, when the locking device 1 is in its closed position, the winding element 35 can be prevented from twisting relative to the first locking member 2 along the load direction B and opposite to the winding direction V.

[0282] According to Figure 29A , 29B In one embodiment, a locking protrusion 255 is additionally formed on the protruding element 252 of each tooth (or at least a portion of these teeth) of the toothed mechanism 351, which, for example, can lockably engage with a corresponding locking notch on the protruding element 252 of the associated tooth of the toothed mechanism 25, so as to additionally prevent the blocking engagement of the teeth of the toothed mechanisms 25, 351 when a load is present in the load direction B.

[0283] according to Figure 30A , 30B Implementation examples and according to Figure 29A , 29B Similar to the embodiments, except that, according to Figure 30A , 30B In the embodiment, the toothed protrusion 252 of the toothed mechanism 351 does not have a locking protrusion 255, as in the embodiment according to Figure 29A , 29B As in the embodiments.

[0284] According to Figure 31A , 31B In this embodiment, the toothed mechanisms 25 and 351 are configured as sawtooth-shaped portions. The teeth of the toothed mechanisms 25 and 351 respectively have tooth sides in the form of impact ramps 253 and vertically extending tooth sides 254. The load on the toothed mechanisms 25 and 351 along the load direction B, which is opposite to the winding direction V, is blocked.

[0285] exist Figure 32A , 32B In the embodiment shown, the teeth of the toothed mechanisms 25 and 351, according to... Figure 31A , 31B Compared to the previous embodiment, the tooth side 254 is undercut, i.e., it is inclined to the closing direction X. Under a load of toothed mechanisms 25 and 351 along a load direction B opposite to the winding direction V, the toothed mechanisms 25 and 351 block each other.

[0286] According to Figure 29A , 29B In embodiments 30A, 30B, and 32A, 32B, the engagement of the toothed mechanisms 25, 351 is self-reinforcing under load in the load direction B. Thus, the locking elements 2, 3 are pulled toward each other under load in the closing direction X. The locking device 1 is also blocked by the form fit of the protruding element 252 or by undercutting, preventing opening in the opposite direction to the closing direction X. In particular, it can absorb and dissipate load forces that are not purely tangential but act with a component opposite to the closing direction X.

[0287] According to Figure 33A , 33B In the embodiment, the teeth of the toothed mechanisms 25 and 351 are inclined at two tooth sides 253 and 254, forming an impact ramp, and the toothed mechanisms 25 and 351 can slide on each other along the winding direction V and also opposite to the winding direction V when the force between the toothed mechanisms 25 and 351 is sufficient, even when the toothed mechanisms 25 and 351 are axially displaced relative to each other. Thus, according to... Figure 33A , 33B In the embodiment, the toothed mechanisms 25 and 351 do not block each other along the winding direction V or opposite to the winding direction V, but can slide on each other in a latching manner when the torque acting between the toothed mechanisms 25 and 351 is large enough.

[0288] exist Figures 34A to 34D In the embodiment shown, the teeth of the toothed mechanisms 25 and 351 extend at their backs inclined to the winding direction V and also inclined to the closing direction X, as in bevel gears. This can increase the surface area of ​​the teeth of the toothed mechanisms 25 and 351 that engages and supports each other under loads opposite to the winding direction V.

[0289] Figures 35 to 68 Different embodiments of the application of the locking device 1 are shown, which can be configured according to the embodiments described above.

[0290] According to Figure 35 In one embodiment, the locking device 1 is used to close and fasten the shoe 5. The locking member 3 can be mounted on the locking member 2 at the tongue of the shoe 5 to fasten the traction element 4 in the form of a shoelace.

[0291] Figure 36 Another embodiment of the shoe 5 is shown, which differs from the embodiment according to FIG18 in that the traction element 4 is wound in the form of a shoelace.

[0292] According to Figure 35 and 36In one embodiment, one end of the traction element 4, which is in the form of a shoelace, is fixed to the locking member 3 of the locking device 1 and can be tightened relative to the locking member 2 by means of the twisting operation element 34 and the winding element 35. The tightening can also be achieved manually by pulling on the locking member 3 before fixing the locking member 3 to the locking member 2, thereby tightening the traction element 4, which is in the form of a shoelace.

[0293] According to Figure 37 and 38 In this embodiment, the two ends of the traction element 4, which is a shoelace-like loop, are connected to the locking member 3 of the locking device 1, so that by twisting the locking member 3 relative to the locking member 2, the shoelace-like traction element 4 can be wound around its two ends and thus tightened. For example, in Figure 38 As shown, the traction element 4 can be manually tightened by pulling it with hand 6 at the traction element 4 before the locking element 3 is placed on the locking element 2.

[0294] According to Figure 39 In this embodiment, the two ends of the traction element 4, which is in the form of a shoelace, are also connected to the locking element 3 of the locking device 1, so that the shoe 5 can be closed and tightened by twisting and wrapping the locking element 3 relative to the locking element 2. The traction element 4, which is in the form of a shoelace, is arranged around the tightening element 50 so that the shoe 5 can be tightened by wrapping the traction element 4 around the winding element 35 of the locking element 3.

[0296] According to Figure 41 In one embodiment, the traction element 4, which is in the form of a shoelace, is arranged around the sole 51 of the shoe 5 and is connected at one end to the locking element 3 of the locking device 1, so that the shoe 5 can be closed and tightened via the locking device 1.

[0297] exist Figure 42 In the embodiment shown, the locking device 1 is used to fasten the trouser leg 52 to the shoe 5 via a traction element 4 in the form of a strap. The traction element 4 extends around the trouser leg 52 and is fixed to the shoe 5 via the locking device 1, such that the trouser leg 52 can be fastened relative to the shoe 5 by twisting the locking member 3 relative to the locking member 2.

[0298] Figure 43 Another embodiment is shown. In this embodiment, the trouser leg 52 can also be fastened relative to the shoe by means that the traction element 4 extending through the eyelets in the trouser leg 52 can be fastened relative to the shoe 5 via the locking device 1.

[0299] According to Figure 44 In one embodiment, the trouser leg 52 can also be fastened relative to the shoe, wherein in this case the traction element 4, in the form of a strap, extends around the sole 51 of the shoe 5 and can be fastened to the shoe 5 via the locking device 1.

[0300] According to Figure 45 and 46 In this embodiment, the locking device 1 is used to close and fasten clothing 5, such as a vest or jacket. A traction element 4, in the form of a strap or rope, is fixed to the clothing 5 at a fixing point 53 and can be arranged around fastening elements 50 on both sides of the opening of the clothing 5 to close the clothing 5 in this manner, as in... Figure 46 As shown in the diagram, the garment 5 can be fastened by placing the locking element 3 on the locking element 2 and by twisting the locking element 3 relative to the locking element 2.

[0301] According to Figure 47 In one embodiment, the locking device 1 is also used to close the garment 5, wherein in this case, two locking devices 1 are used to fasten two traction elements 4. The traction elements 4 are respectively fixed at the fixing part 53 on one side of the opening of the garment 5, and can be fastened on the other side of the opening of the garment 5 by setting the corresponding locking member 3 on the associated locking member 2 of the locking device 1.

[0302] According to Figure 48 and 49 In this embodiment, the locking device 1 is used to close and tighten the medical assistive device 5 in the form of an ankle bandage at the foot 7. The ankle bandage can be closed and tightened by providing a locking member 3 connected to one end of the ankle bandage on a locking member 2 connected to the other end of the ankle bandage and by tightening a traction element 4 extending on the ankle bandage.

[0303] Figure 50 and 51 Another embodiment of the medical assistive device 5 in the form of an ankle bandage is shown, wherein a traction element 4 connected to a locking member 2 at one end and to a locking member 3 at the other end can be arranged around an offset mechanism 54, thereby forming a loop of the traction element 4 by placing the locking member 3 on the locking member 2. The loop can be tightened by twisting the locking member 3 relative to the locking member 2 to close and tighten the ankle bandage.

[0304] Figure 52 A medical assistive device 5 configured as a neck brace is shown, wherein a locking device 1 is used for closing and fastening. A traction element 4 connected to the locking element 3 can be arranged around the fastening hook 50, starting from the fixing point 53, and fastened by twisting the locking element 3 relative to the locking element 2.

[0305] Figure 53 and54 The helmet 5 is shown as an embodiment, such as a bicycle helmet, in which the locking device 1 is used to close and tighten the belt 55. The traction element 4 is part of the belt 55 and can be wound around the locking member 3, that is, around the winding element 35 of the locking member 3, so as to tighten the belt 55 in this way.

[0306] According to Figure 55 and 56 In one embodiment, the locking device 1 is used to fasten the helmet 5, such as the chin strap 56 of a bicycle helmet. The locking member 3 of the locking device 1 may be disposed on the locking member 2 and twisted relative to the locking member 2 in order to fasten the strap 56 in this way.

[0307] According to Figure 57 In this embodiment, the locking device 1 is used to adjust the height of the lamp-shaped component 5. The traction element 4 is used to suspend the lamp. By twisting the locking member 3 of the locking device 1, the length of the traction element 4 can be changed, thereby setting the height of the lamp.

[0308] According to Figure 58 In one embodiment, the locking device 1 is used to suspend the painting-shaped component 5. The length of the traction element 4 can be changed by twisting the locking member 3 to match the suspension method of the painting.

[0309] exist Figures 59 to 61 In the embodiment shown, the locking device 1 is used for electrical connection to the component in the form of a lamp 5. The locking member 2 is configured as a plug for this purpose. The locking member 3 can be twisted relative to the plug-shaped locking member 2 in order to change the length of the free extension of the wire realizing the traction element 4.

[0310] According to Figure 62 In one embodiment, the locking device 1 is used to fasten the component 5, which is in the form of a louver. The locking element 3 is connected to the louver via the traction element 4. The louver can be adjusted by winding the traction element 4 by, for example, setting the locking element 2 on the frame and by twisting the locking element 3.

[0311] According to Figure 63 In the embodiments, with respect to Figure 62 In a different embodiment, the two ends of the traction element 4 are connected to the locking element 3, so that by twisting the locking element 3, the two ends of the traction element 4 can be simultaneously wound onto the winding element 35 of the locking element 3.

[0312] exist Figure 64 In the embodiment shown, the locking device 1 is used to fasten the traction element 4, which is in the form of a strap on a piece of luggage.

[0313] exist Figure 65In the embodiment shown, the locking device 1 is used to fasten the strap or rope-like traction element 4 to the backpack-shaped luggage item so as to secure the item to the luggage item in this way.

[0314] exist Figure 66 In the embodiment shown, the locking device 1 is used to secure an item 5, such as a mobile phone, to a bicycle, particularly the handlebars. The traction element 4 is wound around the item 5 and can be secured by partially winding around the winding element 35 of the locking member 3.

[0315] Figure 67 Another embodiment of a different winding method for securing an item 5, such as a mobile phone, to a bicycle via a traction element 4 is shown.

[0316] exist Figure 68 In the embodiment shown, the locking device 1 is used to secure items, such as luggage, in the vehicle's luggage compartment. A traction element 4 is positioned beyond the luggage and thus holds the luggage in place at the bottom of the luggage compartment. The traction element 4 can be fastened via the locking device 1 to secure the luggage.

[0317] Figures 69 to 73 Another embodiment of the locking device 1 is shown, wherein the locking elements 2 and 3 can be arranged close to each other along the closing direction X and held close to each other in the closed position.

[0318] According to Figures 69 to 73 In one embodiment, the traction element 4 is configured as a strap that can be wound around a winding element 35 in the form of a sleeve, which is a locking member 3. The locking member 3 can be mounted on a locking member 2, which has, for example, a buckle, such that the ends of the traction elements 4 can be connected to each other and fastened relative to each other via the locking device 1.

[0319] The locking member 3 has an operating element 34 with a handle formed thereon, the handle being engageable with the engagement mechanism 355 of the winding element 35 via an engagement mechanism 345, such that the winding element 35 can be twisted relative to the locking member 2 in the winding direction V via the operating element 34.

[0320] For example, especially from the basis Figure 73 As can be seen in the cross-sectional view, the operating element 34 has a bolt 346 with an engagement opening 347. By means of the bolt, the operating element 34 is fitted onto the cylindrical section 201 of the body 20 of the closing member 2 in the closing direction X so as to connect the locking members 2 and 3 to each other.

[0321] For example, due to the spring preload between the operating element 34 and the winding element 35, the engagement mechanisms 345 and 355 do not engage with each other when the locking elements 2 and 3 are separated. Thus, the winding element 35 can freely twist relative to the operating element 34, allowing the traction element 4 to unwind, for example, from the winding element 35. For closure, the locking element 3 is placed on the locking element 3 such that the engagement opening 347 at the pin 346 of the operating element 34 engages with the cylindrical section 201 of the locking element 2, wherein the winding element 35 is supported on the body 20 of the locking element 2 and is attracted by the magnetic elements 23 and 33, on one side on the cylindrical section 201 and on the other side on the pin 346 of the operating element 34 (see...). Figure 73 The operating element 34 is attracted toward the winding element 35, thereby engaging the mechanisms 345 and 355 to achieve a form-fitting engagement. In this way, an effective connection is established between the operating element 34 and the winding element 35, so that when the locking elements 2 and 3 are connected to each other, the operating element 34 and the winding element 35 can be twisted together to wind the traction element 4 onto the winding element 35 and thus tighten the traction element 4.

[0322] At the end facing the body portion 20, the winding element 35 has a toothed mechanism 351 with serrated teeth that engages with the toothed mechanism 25 at the body portion 20 when the locking members 2 and 3 are connected to each other. The engagement of these toothed mechanisms 25 and 351 causes the locking members 2 and 3 to be able to twist relative to each other along the winding direction V so as to fasten the traction element 4 to the traction element 35, but not to the winding element V.

[0323] In order to release the locking device 1, the locking elements 2 and 3 can be removed from each other in the opposite direction of the closing direction X, so as to separate the locking elements 2 and 3 from each other in this way.

[0324] Figure 74A and 74B This shows the situation when locking elements 2 and 3 are separated ( Figure 74A When the locking device 1 is closed () Figure 74B The locking device 1 can be used, for example, to fasten a belt in the form of a waistband.

[0325] Figure 75 Another embodiment of the locking device 1 is shown, wherein the locking elements 2 and 3 can be arranged close to each other along the closing direction X, similar to that described above.

[0326] According to Figure 75 In one embodiment, a transmission mechanism 26 is disposed on the locking member 2. This transmission mechanism may, for example, have a conical transmission mechanism or a worm gear transmission mechanism configuration and is used to engage with the toothed mechanism 351 of the locking member 3 via a toothed mechanism 25 (which, when the locking members 2 and 3 are connected to each other, for example from...). Figure 69 (As can be seen in the image) the locking element 3 is twisted relative to the locking element 2 in order to tighten the traction element 4 in this way. Thus, according to... Figure 75 In one embodiment, the torsion of the locking elements 2 and 3 relative to each other is performed via a transmission mechanism provided on the locking element 2, which can be operated manually, for example.

[0327] Figures 76 to 79A 79B shows another embodiment in which such a transmission mechanism 26 is implemented for securing the winding element 35.

[0328] According to Figures 76 to 79A In the embodiment of 79B, the transmission mechanism 26 is configured as a tensioning transmission mechanism, wherein the tensioning rod 260 is pivotally supported on the body 20 of the locking member 2 about a pivot axis 265 and is preloaded relative to the body 20 to an initial position (in) via a spring element 261. Figure 79A , 79B (As shown in the image).

[0329] In this embodiment, the locking member 3, together with the winding element 35, can be fitted onto the cylindrical section 201 of the body 20 and, in the connected position, engages with the associated toothed mechanism 25 of the body 20 via the toothed mechanism 351, as also described above. A fastening engagement portion 356 in the form of a toothed portion is formed at the winding element 35, the toothed portion extending around the winding element 35 and used to interact with the transmission mechanism 26.

[0330] On the tension rod 260 of the transmission mechanism 26, a connecting rod 262 is pivotally provided around the pivot axis 263, the connecting rod being used to engage with the tensioning engagement portion 356 of the winding element 35.

[0331] To ensure that locking elements 2 and 3 are positioned close together, tension rod 260 can, for example, in Figure 78A , 78B As shown, the engagement rod 262 is offset from its initial position along the pivot direction P1 so as to remove the engagement rod 262 from the area occupied by the winding element 35 when the locking members 2 and 3 are connected to each other. The locking members 2 and 3 can thus be easily and closely positioned to each other without being obstructed by the transmission mechanism 26.

[0332] If the tension rod 260 is released again, then the transmission mechanism 26 and its tension rod 260 will reach the desired state according to... Figure 79A , 79B In the initial position, the engaging rod 262 engages with the tensioning engagement portion 256.

[0333] If the tension rod 260 shifts in the pivot direction P2 from now on, the connecting rod 262 moves together and the winding element 35 twists in the winding direction V, causing the traction element 4 to wrap around the winding element 35. Thus, the traction element 4 is tightened.

[0334] The tightening is performed gradually. Due to the spring element 261 and the spring prestress provided therefrom, the tension rod 260 automatically returns to its initial position after operation, wherein, in the event of elastic displacement of the spring element 264, the engaging rod 262 slides back and forth on the tightening engagement 356, elastically pre-tensioning relative to the tension rod 260 via the spring element engaging rod 262. Thus, the tightening of the traction element 4 is performed gradually by repeatedly operating the tension rod 260.

[0335] One-way movement (Freilauf) is also provided via spring element 264. The winding element 35 can also be twisted by hand along the winding direction V. Here, the engagement 262 slides on the tension engagement 356 of the winding element 35 due to the elastic offset of spring element 264.

[0336] The ideas upon which this invention is based are not limited to the embodiments described above, but can in principle be implemented in completely different forms.

[0337] The locking device of the type described herein combines mechanical locking and a winding mechanism. The locking elements can be positioned close to each other and held close to each other in the closed position. The traction element can be wound and tightened here via the winding element, so that the components can be connected to each other and tightened relative to each other.

[0338] Traction elements are typically, for example, configured as flexible elements suitable only for transmitting traction. Traction elements can be, for example, ropes, belts, or strips.

[0339] The locking device of the type described herein can be configured as a purely mechanical locking device without the application of magnetic elements. However, the use of magnetic elements can be advantageous, on the one hand achieving simple and intuitive operability, and on the other hand improving the retention between the locking elements.
