Description

Locking device for a connecting element and closing arrangement

The invention relates to a locking device for a connecting element and a closing arrangement.

Fasteners such as screws, rivets, bolts, nuts or nails are used in many areas of technology. Often they are used to connect low weight mobile components that can easily become the object of theft. Examples of such components are parts of a bicycle, such as a rim, a saddle, a handlebar fork or a bicycle lock. There is therefore a considerable need for a device which is suitable for securing such connecting elements against unauthorized access, in order to protect the components connected to the connecting elements in this way against theft.

In the document DE 35 38 244 AI a lock for securing fastening nuts is proposed. The lock proposed there takes but a lot of space and includes a variety of components. For example, a key is required for its operation. The material costs for its production are thus comparatively high. Due to its bulky shape, it is also not flexible.

The present invention is therefore based on the object to develop a device for securing a connecting element against unauthorized access, wherein the device consists of the smallest possible number of components and should have the most compact form possible.

This object is achieved by a locking device according to claim 1 and by a locking arrangement according to claim 20. Advantageous developments of the invention are described in the subclaims. Proposed is a locking device for a connecting element, wherein the locking device comprises a first closing body with first locking elements and a second closing body with second locking elements and wherein the closing body form a combination lock such that the closing body in a locked position by means of the first and the second locking elements form fit into each other grab that in an unlocked position caused by the locking elements positive engagement of the closing body is canceled or the closing body are spatially separated and

that the closing bodies are arranged to be brought from the locked to the unlocked and from the unlocked to the locked position by means of a change of a relative arrangement to one another,

wherein the first closing body and / or the second closing body in the locked position, a space for receiving at least a portion of the connecting element or for receiving at least a portion of an element permanently connected to the connecting element

engage behind / engages and wherein the first closing body and / or the second closing body in the locked position, the space at least partially surround / encloses such that access to the space is prevented. It is expressly understood that the connecting element is not part of the claimed locking device. If the connecting element as part of a specific embodiment of the claimed

Closing device is claimed, it is expressly lent noted. However, that the connecting element is part of the invention is then limited to this special case.

Because the locking device is designed as a combination lock, no further components for operating the locking device, such as a key, are required in addition to the closing bodies.

In the locked position, the closing bodies preferably engage in one another in a form-fitting manner such that centers of gravity of the first and second closing bodies are not or are hardly movable relative to one another.

The fact that the first and / or the second closing body in the locked position engages / engages behind a space which is adapted to receive the connecting element or at least a part of the connecting element, it is possible, the connecting element in the locked position so with the Entschließken locking device that the connecting element is not spatially separable from the locking device. Preferably, the connecting element and the closing device engage in one another in the locked position in a form-fitting manner. The engaging behind the space through the locking device can be given in the form of an undercut.

By virtue of the fact that the first closing body and / or the second closing body in the locked position surround / surround the space at least partially in such a way that access to the space is prevented, a connecting element which in the locked position can at least partially be in the space arranged or enclosed by the locking device, not be operated. The locking device can enclose the space in the locked position in such a way that it is impossible to actuate the connecting element or the part of the connecting element enclosed by the locking device with a tool, for example a wrench or screwdriver. One in the locked position arranged in the space part of the connecting element can be quite visible.

Preferably, both closing bodies have a cylindrical or almost cylindrical shape. At least one of the closing bodies may be at least partially formed as a hollow cylinder, wherein one of the closing body is arranged to at least partially enclose the respective other closing body at least in the locked position. As a result, the locking device can be designed to save space. A cylindrical shape without sharp corners or edges can also reduce the risk of injury.

In an advantageous embodiment of the invention, the connecting element is designed as a screw, nut, bolt or rivet. Thus, the locking device is particularly versatile. Preferably that is

Connecting element part of a bicycle or a motor vehicle. For example, the connecting element may be arranged for fastening a rim, a saddle, a steering wheel fork or a bicycle lock to a bicycle.

In a further advantageous embodiment of the invention is the

Locking device at least partially made of metal, preferably made of stainless steel. Metal is particularly stable and can not be destroyed without special tools. This makes the locking device particularly stain-proof. Furthermore, metal is very durable, heat resistant and can be processed well. The closure device may also comprise other metals such as iron, copper, aluminum or titanium. Preferably, a proportion of metal-made components on the

Closing device at least 80, preferably at least 90 weight percent. The locking device may also be partially made of plastic or

Be formed ceramic.

In a further advantageous embodiment of the invention, the

Closing device a weight of at most 300 grams, preferably of at most 200 grams, more preferably of at most 100

Grams. Thus, the locking device is particularly easy to handle. In a further advantageous embodiment of the invention, the

Locking device in the locked position a length of at most 5 cm, preferably of at most 3 cm, a width of at most 4 cm, preferably of at most 2.5 cm and a height of at most 4 cm, preferably of at most 2.5 cm. Thus, the locking device can also be used to complete difficult to access fasteners, such as those used in recesses or within small containers. The small dimensions also make the locking device particularly handy, so that it can easily be stored or transported in a jacket or trouser pocket.

In a further advantageous embodiment of the invention, the change in the relative arrangement includes a relative rotation between the first and the second closing body about a common in the closed position of the first axis of rotation of the first and second closing body. In the locked position, the first closing body and the second closing body are then rotatable relative to each other. As long as the

Closing device is not brought by this relative rotation in the unlocked position, the positive connection between the first closing body and the second closing body, which prevents relative movement of the mass centers of gravity of the closing body to each other, then by the relative rotation of the closing body in the locked position not canceled. The first axis of rotation defines an axial direction of the

Locking. Typically, there is a recessed position in which one of the two closing body is at least partially embedded in the respective other closing body and is enclosed by this. However, the recessed position is an unlocked position in the sense that the first and second locking elements in the recessed position are not positively engaged, so that the centers of gravity of the two closing bodies in the recessed position are movable relative to each other, preferably along the axial direction. From the recessed position, the locking device can be brought by rotation of the two closing body relative to each other in the locked position. By a pure translational movement of the two closing bodies relative to each other, preferably along the axial direction, the two closing body can the recessed position are brought into a position in which the two closing bodies are spatially separated.

In a further advantageous embodiment of the invention, the first locking elements are formed as first projections and / or as first recesses and the second locking elements are formed as second projections and / or as second recesses. The first and / or the second locking elements can protrude perpendicularly from the closing body on which they are respectively arranged. The first and / or the second locking elements may be arranged on an inner side and / or on an outer side of the closing body. Typically, the first and / or the second locking elements are about one millimeter from the respective closing body. The locking elements may be formed as annular projections with recesses. The first and / or the second locking elements typically extend over a distance of about one millimeter to a few millimeters along the closing body, from which they each protrude.

In a further advantageous development of the invention, the first locking elements are made at least partially from the same first workpiece as the first closing body and / or the second locking elements are at least partially made from the same second workpiece as the second closing body. Thus, the locking elements are particularly firmly connected to the respective closing body, so that a stability and security of the locking device are advantageously increased. However, the locking elements can also form-fitting or cohesively with the respective

Be connected closing body. An adhesive bond may include soldering, welding or vulcanization.

In a further advantageous development of the invention, the first locking elements and / or the second locking elements have, in the locked position along the axial direction, aligned surfaces with which the first and the second locking elements in the locked position when exercising along the axial direction between the first and the second locking elements effective force positively engage with each other such that the relative rotation between the first and the second closing body is prevented. Thus, the locking device is special this is theft proof. In this way, it is not possible to simultaneously pull apart the closing bodies and to rotate relative to one another. Typically, the elevations are in the form of recesses and elevations. Typically, the surfaces of the Riegelele- elements on which the profiles are arranged or in which the profiles are embedded, perpendicular to the axial direction.

In a further advantageous embodiment of the invention, the second closing body comprises at least a first closing element and a second closing element, wherein the closing elements permanently in positive

Engage with each other and are rotatable relative to each other about a common second axis of rotation. The more closing elements the second closing body comprises, the greater the number of possible relative orientations, i. Combinations of the closing elements. The second axis of rotation may be in the locked position with the first axis of rotation, i. with the axial

Coincide direction. If only exactly one relative orientation of the closing elements to one another and to the first closing body corresponds to the unlocked position, the safety of the closing device is thereby increased. The second closing body can also comprise more than two closing elements. Typically, the individual closure elements have an annular, cylindrical, disc-like or hollow-cylindrical shape. The closing elements can be connected to each other by clamping rings. The closing elements can also be directly in mutual positive engagement with each other.

In a further advantageous development of the invention, the first closing body has first markings and the second closing body has second markings, the unlocked position being characterized by a relative orientation of the first and second markings and an arrangement of the first markings relative to the first closing body and / or wherein an arrangement of the second markings is variable relative to the second closing body. Due to the fact that the arrangement of the first markings relative to the first closing body and / or that the arrangement of the second markings is variable relative to the second closing body or relative to the closing elements of the second closing body, a "correct" combination of the markers, ie the unlocked Position corresponding arrangement of the closing elements relative to the first closing body to be changed again and again. For example, if an unauthorized person knows the "right" combination, the combination can be changed so that it is no longer easy for the unauthorized person to open the combination lock, thus making the locking device particularly theft-proof and / or the second markers are arranged to be changeable in their arrangement relative to the first or the second closing body only if the first and the second closing body are spatially separated.

In a further advantageous embodiment of the invention, the closing elements and the first closing body are coupled in the locked position via a differential friction mechanism such that when rotating only one of the closing elements in a first direction of rotation relative to the first closing body, a friction between the closing elements is greater than one

Friction between the individual closing elements and the first closing body and that when rotating only one of the closing elements in a first rotational direction opposite second rotational direction relative to the first closing body friction between the closing elements is smaller than a friction between the not rotated in the second direction of rotation

Closing element and the first closing body. This is the

Locking device particularly easy to operate. In this way, at least two of the closing bodies can be brought into a desired arrangement relative to the first closing body by actuating only a single one of the closing bodies.

In a further advantageous embodiment of the invention, the friction between the individual closing elements and the first closing body by complementary projections and / or recesses in or on each mutually facing surfaces of the closing elements and the first

Realized closing body. For example, the respective facing surfaces may have a plurality of axially extending grooves and protrusions, each interlocking by a weak form fit, so that the positive engagement by applying a small force, as it can be easily spent with the fingers , is repealable. In relative rotation, for example, one of the closing elements relative to the first closing body can thus be given a discrete number of latching contacts. The number of such latching contacts may be different between different closing elements or between different closing elements and the first closing body.

In a further advantageous embodiment of the invention, the friction between the closing elements and / or the friction between the individual closing elements and the first closing body by corresponding sawtooth profiles and / or recesses on mutually facing surfaces of the closing elements and / or on mutually facing surfaces of the individual closing elements and realized the first closing body. This can be achieved in a simple manner that, for example, adjacent closing elements are rotatable relative to each other only in one direction of rotation.

In a further advantageous embodiment of the invention, the first closing body encloses a preferably cylindrical interior which is continuous from an upper side of the first closing body to an underside of the first closing body, wherein a receiving opening in the upper side for receiving the connecting element is larger than a retaining opening in the lower side Behind at least a part of the connecting element. In this case, the first closing body is thus designed, for example, as a hollow cylinder, which is partially closed at least on the underside. Typically, the retaining opening is just large enough to allow a pin-like part of the connecting element, for example a

Screw neck, can be passed. A surface of the retaining opening may then be smaller than, for example, a cross section of a head of the screw, so that an undercut for engaging behind the head of the screw is realized by the retaining opening in the underside of the first closing body. Through the receiving opening, the screw can then be inserted into the first closing body and also removed from it.

This embodiment of the locking device is particularly advantageous because the locking device is used in this way to complete a plurality of different fasteners can. The locking device is therefore particularly flexible use. For example, the locking device can be used in this case to complete screws of any length. Decisive in each case only that the first closing body engages behind the head of the screw by means of the partially open bottom, so that in the locked position with the

Closingvorvor direction entangled or positively connected.

In this context, it is particularly advantageous if the underside of the first closing body is at least partially designed as an exchangeable disc, wherein the retaining opening is then embedded in the disc. In this case, the disc is advantageously arranged to be replaced by the receiving opening through, wherein a arranged at a lower end of a main body of the first closing body and at least partially inwardly extending collar of the body at least partially engages behind the disc. Of course, the replacement of the disc in this case can only be made when the locking device is in the unlocked position. In this way, the closing device can easily be closed off, e.g. be used by screws with different thickness screw neck, namely by a surface of the retaining hole of the thickness of the respective screw neck can be adjusted.

In a further advantageous development of the invention, the first closing body is arranged to at least partially enclose the second closing body in the locked position, wherein the second closing body closes the interior space enclosed by the first closing body in the locked position towards the top side and wherein the second closing body closes Locking body in the locked position is accessible through the receiving opening. In this case, therefore, the first closing body is formed, for example, as a hollow cylinder, and the second closing body has a complementary cylindrical body

Form, wherein a radius or an outer radius of the second closing body is a little smaller than an inner radius of the hollow body designed as a first closing body. This is particularly advantageous where the locking device is to be inserted into a body, because the connecting element to be terminated is arranged, for example, on a bottom of, for example, a cylindrical recess in the body. If the first closing body at least partially encloses the second closing body in the locked position, it is particularly advantageous if the first closing element is designed as a hollow cylinder, wherein an outer radius of the first closing element is a little smaller than a radius of the inner space. The second closing element is then advantageously at least partially cylindrical, wherein a radius of the second closing element in a cylindrical part of the second closing element is a little smaller than the radius of the inner space and wherein the second closing element is accessible through the first closing element and / or wherein the second closing element engages at least partially through the first closing element. The closing elements can be arranged nested in this case. By forming the first closing element as a hollow cylinder, it is possible to access both closing elements from the upper side of the first closing body, ie through the receiving opening. If three closing elements are provided, then it is expedient if at least two of them are designed as hollow cylinders, wherein the hollow cylinders can then be nested one inside the other.

In a further advantageous development of the invention, the first and / or the second closing element have / at a top side of the first and / or the second closing element which faces in the locked position of the receiving opening a functional profile for engaging a tool. Thus, the closing elements can be operated particularly comfortable. For example, it may be a profile for receiving an Allen wrench or a screwdriver.

In a further advantageous embodiment of the invention, the second markers are formed as pins, wherein the pins are adapted to be inserted into holes which are provided at a facing in the locked position of the receiving opening top of the first closing element and / or the second closing element. Advantageously, the pins are then additionally formed in different colors. The pins can be made of plastic. If the first closing body at least partially surrounds the second closing body, it is particularly advantageous if a spring is arranged between the underside of the first closing body and the second closing body, ie inside the interior, the spring being in the locked position one towards the top the first closing body directed toward the second closing body exerts such that the second closing body is arranged to be at least partially pushed out of the space enclosed by the first closing body interior, as soon as the

Locking device from the locked position e.g. is brought into the recessed position by rotation of the closing elements relative to the first closing body. This facilitates removal of the second closing body from the first closing body, when the closing body, e.g. to be spatially separated for actuating the connecting element. In a further advantageous embodiment of the invention, the second

Lock body arranged to at least partially enclose the first closing body in the locked position. The second closing body can then be at least partially formed as a hollow cylinder. In this case, the closing elements provided for locking and unlocking can be e.g. be arranged along an outer surface of the locking device.

They are thus particularly easily accessible.

In a further advantageous embodiment of the invention, the closing elements are annular. Typically, the second closing body then has the shape of a hollow cylinder and the closing body form at least a part of a lateral surface of this hollow cylinder.

If the second closing body at least partially surrounds the first closing body, it is particularly advantageous if the second markings are designed as marking rings, wherein a marking ring is assigned in each case to one of the annular closing elements and arranged on an outer side of the respectively associated closing element, and wherein a marking ring and each associated with him annular closure element in positive and / or non-positive engagement with each other. The marking rings may be formed of plastic. Preferably, the

Positive engagement between the closing elements and the marking each realized by running in the axial direction complementary groove-like structures on an outer side of the closing elements and on an inner side of the marking rings realized. Thus, the marking rings can be easily mounted on the closing elements and removed from the closing elements.

Furthermore, a closing arrangement is proposed which a

Locking device according to one of claims 22 to 24, wherein the closing arrangement has a connecting element and wherein the connecting element and the first closing body are made in one piece. In this case, the connecting element forms part of the claimed invention. In this case, the first closing body forms part of the connecting element or the first closing body is permanently connected to the connecting element, for example by a soldered connection or by a welded connection. Thus, the first locking elements are preferably permanently connected to the connecting element. The connecting element in this case is therefore not, for example, a conventional screw, but e.g. around a screw or a nut with a specially shaped head, on which the first locking elements are arranged. The engaging behind the space for receiving the connecting element according to the invention can be realized in this case alone by the second locking elements without the room a

Undercut in the true sense needs. The one of the

Locking device in the locked position behind the room is in this case as the directly from the first closing body and the first

To understand locking elements of the first closing body occupied space so that the engagement of the space is realized in the locked position by the positive engagement of the first and the second locking elements.

An advantageous development of the closing arrangement comprises a third body, wherein the second closing body acts in the locked position as a spacer between the first closing body and the third body. Likewise, the first closing body in the locked position may act as a spacer between the third body and the second closing body. If the second closing body in the locked position acts as a Stands holder between the third body and the first closing body, so may be set by the second closing body in the locked position, a minimum distance between a center of gravity of the third body and a center of gravity of the first closing body. In this case, the first closing body and the third body can partially enclose each other. The same applies to a distance between the third body and the second closing body, when the first closing body in the locked position serves as a spacer between the second closing body and the third body. The third body may also be formed of metal or plastic and have a weight of at most 300 grams, preferably less than 100 grams, more preferably less than 50 grams. The third body may be disc-shaped.

A further advantageous development of the closing arrangement comprises an eccentrically mounted on a shaft and fixedly connected to the shaft cam, which is arranged between the first closing body and the third body, wherein a distance between the first closing body and the third body by a variable arrangement of the cam is controllable. Preferably, the distance, which in each case refers to the centers of mass of the third body and the first closing body and the second closing body, only in the unlocked position by means of the cam controllable. The shaft can be positively connected to the third body or with the locking device. On the shaft, a lever may be arranged, by means of which a torque can be transmitted to the shaft, so that the cam can be actuated via the lever. Preferably, the third body, shaft and cam together weigh less than 300 grams.

In a further advantageous development of the closing arrangement, the closing arrangement is set up to be arranged on an axle, preferably on a front axle or a rear axle of a bicycle, wherein the first closing body is arranged to be fixedly connected to the axle. This arrangement is therefore preferably a closing arrangement for closing a quick-release device on a front axle or rear axle of a bicycle. It should be emphasized that the axle itself is not part of the claimed locking arrangement in this embodiment. The fixed connection between the first closing body and the axle is preferably a positive connection, for example a screw connection. For example, the first closing body may be at least partially hollow and have an internal thread. The third body is then preferably arranged to enclose the axis of the bicycle. The third body is then between the

Locking device and the rim arranged on the bicycle axle and can be pressed by means of the cam for tightening the wheel against the rim or against a arranged between the third body and the rim bicycle fork.

Fig. 1 shows a locking device 101 for a connecting element 102, which is designed as a screw. The connecting element 102 itself is not part of the locking device 101. The locking device 101 comprises a first closing body 103 and a second closing body 105, each being different from the connecting element 102. The first

Closing body 103 has the shape of a hollow cylinder. The first closing body 103 encloses a cylindrical inner space 121, which is continuous from an upper side 119 of the first closing body 103 to a lower side 120 of the first closing body 103. The inner space 121 is accessible to the upper side 119 of the first closing body 103 through a receiving opening 122. FIG. 1 does not show that the first closing body 103 has a retaining opening 123 in the lower side 120. The retaining opening 123 in the lower side 120 of the first closing body 103 is covered in FIG. 1 by a head 108 of the connecting element 102. A radius of the round retaining opening 123 is smaller than a radius of the round head 108 of the connecting element 102. However, a neck 152 of the connecting element 102 has a radius which is smaller than the radius of the retaining opening 123. A radius of the likewise round receiving opening 122 in FIG

The upper side 119 of the first closing body 103 is larger than the radius of the head 108 of the connecting element 102. In particular, the receiving opening 122 is larger than the retaining opening 123. Thus, the receiving opening 122 is adapted to receive the connecting element 102 with the neck 152 in front, the neck 152 through the retaining opening 123

can be inserted. In this case, the retaining opening 123 or the lower side 120 of the first closing body 103, in which the retaining opening 123 is recessed, engages behind the head 108 of the connecting element 102. The inner space 121 enclosed by the first closing body 103 is accordingly arranged, at least the head 108 of the connecting element 102 to receive. At the bottom 120 of the first closing body 103 engages behind the interior 121 enclosed by it.

Here and in the following, a coordinate system fixedly connected to the first closing body 103 is defined by the first closing body 103. In this case, a z-direction 135 should be given by an axis of symmetry (shown in dashed lines in FIG. 1) of the first closing body 103. The axis of symmetry is a cylinder axis of the first closing body 103 designed as a hollow cylinder. The axis of symmetry is referred to below as the first axis of rotation 111. An x-direction 136 and a y-direction 137 are each perpendicular to the z-direction 135. A positive z-direction should be directed upward in FIG. Accordingly, a negative z-direction in the Fig. 1 directed downward.

Due to the fact that the first closing body 103 engages behind the cylindrical inner space 121 enclosed by it in the manner described, it is not possible to separate the connecting element 102 in the negative z-direction from the first closing body 103.

The second closing body 105 is of substantially cylindrical shape and comprises a first closing element 114 and a second closing element 115.

In this case, the first closing element 114 is formed as a hollow cylinder whose outer radius 125 should be slightly less than 1 cm in the present example. The outer radius 125 of the first closing element 114 is thus only slightly smaller than an inner radius 126 of the first closing body 103, ie a radius of the inner space 121. The second closing element 115 is shown only partially in FIG. Also visible is a cylindrical part of the second closing element 115 which engages at least partially through the first closing element 114 formed as a hollow cylinder. The first closing element 114 thus encloses the second closing element 115 at least partially. The second closing element 115 is accessible from an upper side 128 of the first closing element 114. The first closing element 114 and the second closing element 115 of the second closing body 105 are permanently in positive engagement with each other and are rotatable relative to each other about a common second axis of rotation. In FIG. 1, this second axis of rotation coincides with the first axis of rotation 111. The first closing body 103 and the second closing body 105 together form a combination lock. For this purpose, the first closing body 103 has on an inner side first locking elements 104a and 104b. Correspondingly, the second closing body 105 has on an outer side second locking elements 106a and 106b, of which only the second locking elements 106a can be seen in FIG. 1, which are arranged on a cylinder jacket-shaped outer surface of the first closing element 114. The second locking elements 106b, which are arranged on a corresponding outer surface of the second closing element 115, are not shown in FIG. 1 for the sake of clarity. The second locking elements 106a are - like the second locking elements 106b (not shown here) - formed as projections, which rotate around the lateral surface of the first closing element 114 perpendicular to the symmetry axis of the second closing body 105 partially. The second locking elements 106a each protrude perpendicularly from the outer surface of the first locking element 114 by about 1 mm. Along the symmetry axis of the second closing body 105, which coincides with the z-direction in FIG. 1, the locking elements 106a each extend over approximately 1 mm. In a direction perpendicular thereto, the locking elements 106a each extend over a few millimeters. The locking elements 106a are given by ring-like structures, which are each interrupted by recesses. Along the z-direction a plurality of such ring-like structures at a distance of about 1 mm on the lateral surface of the first closing element 114 are arranged.

In Fig. 1, the first closing body 103 and the second closing body 105 are shown spatially separated. In Fig. 1 are the first closing body

103 and the second closing body 105 thus in an unlocked position. If the first closing body 103 and the second closing body 105 are spatially separated as shown in FIG. 1, then the head 108 of the connecting element 102 which is engaged behind the first closing body 103 and by the first closing body 103 is inserted through the receiving opening 122 in the upper side 119 of FIG first closing body 103 accessible therethrough. In particular, the connecting element 102 can thus be actuated through the receiving opening 122 by means of a tool, for example an Allen wrench or a screwdriver.

Also arranged on the inside of the first closing body 103 ers- The locking elements 104a and 104b are formed as projections, which are arranged on the inside of the first closing body 103 and project perpendicularly from the inside of the first closing body. Like the second locking elements 106a arranged on the lateral surface of the first closing element 114, the first locking elements 104a and 104b are arranged in an annular manner and are each interrupted by recesses. Also, the first locking elements 104a and 104b extend in the z-direction and along the inner surface of the first closing body 103 in each case by at most a few millimeters. In the present example, both the first closing body 103 and the second closing body 105 are each made almost entirely of stainless steel. For example, made of stainless steel components of the locking device 101 at least 90% of a weight of

Locking device 101 off. The weight of that shown in FIG

Closing device 101 is about 100 g. Like the closing body 103, the first closing elements 104a and 104b arranged on the inner side of the first closing body 103 are also made of stainless steel and manufactured with the first closing body 103 from the same first workpiece. Also, the second closing body 105 and arranged on the surface of the second closing body 105 second locking elements 106a are made of the same second workpiece made of stainless steel.

The first locking elements 104a and 104b of the first closing body 103 are designed to be complementary to the second locking elements 106a and 16b of the second closing body 105. This means that there is exactly one relative orientation of the first closing element 114 and the second closing element 115 relative to each other, in which the second closing body 105 can be inserted from the position shown in FIG. 1 into the inner space 121 enclosed by the first closing body 103, without the first locking elements 104a and 104b and the second locking elements 106a and 106b are in the way. After the second closing body 105 has been inserted from the position shown in FIG. 1 by means of a pure translational movement in the negative z-direction into the inner space 121 of the first closing body 103, the first closing body 103 surrounds the second closing body 105.

If the second closing body 105 is embedded in the inner space 121 of the first closing body 103, then the first closing body 103 and the second closing body 103 can be inserted Closing body 105 are brought by rotation of the first closing element 114 or by rotation of the second closing element 115 about the rotation axis 111 in a locked position in which the first locking elements 104a and 104b and the second locking elements 106a engage in a form-fitting manner. In other words, the first closing body 103 and the second closing body 105 can be brought from the unlocked position to the locked position by means of a change of a relative arrangement to each other. Likewise, it is possible to bring the first closing body 103 and the second closing body 105 back into the recessed position by means of a change in relative position of the closing bodies from the locked position, in which the first locking elements 104a and 104b and the second locking elements 106a and 106b not intermeshing one another and representing an unlocked position. From the recessed position, the first closing body 103 and the second closing body 105 can again be brought into a spatially separated position by the second closing body 105 executing a pure translational movement in the positive z-direction.

In FIG. 1, it can further be seen that the first closing body 103 has first markings 116. The first marks 116 are shown in FIG

Letter pairs are formed, which are engraved along a circumference of the first closing body 103 at regular intervals in the top 119 of the first closing body 103. Likewise, the second closing body 105 on the upper side 128 of the first closing element 114 and on an upper side 129 of the second closing element 115 respectively second markings

117a and 117b. The markings 116, 117a and 117b are highlighted again in FIG. In this case, the unlocked position is characterized by a relative orientation of the first markings 116 to the second markings 117a and 117b. This means that the first closing body 103 and the second closing body 105 can be brought from the locked position to the recessed position by aligning the second marks 117a and 117b with the first marks 116 respectively in accordance with the relative orientation.

In the example shown in FIG. 1, the second markings 117a and 117b are formed as pins which engage in corresponding holes in the upper side 128 of the first closing element 114 and in the upper side 129 of the second closing element 114. elements 115 are embedded. In Fig. 3 it can be seen that the second markings 117a and 117b are designed in different colors. The top 128 and the top 129 are in the locked position of the receiving opening 122 in the top 119 of the first closing body 103 faces. The marks 117a and 117b are formed as different colored plastic pins, which can be removed in the position shown in Figure 1, in which the first closing body 103 and the second closing body 105 are spatially separated from the holes in which they are respectively inserted so that they can subsequently be arranged in a different relative arrangement to the first closing element 114 and the second closing element 115. In other words, an arrangement of the second markings 117a and 117b relative to the second closing body 105 is variable. Thus, the relative orientation of the first marks 116 and the second marks 117a and 117b corresponding to the unlocked position can be changed as desired. This will be a security of

Closing device 101 increased.

2 shows a y-z-section through the closing device 101 in the locked position of the closing body 103 and of the second closing body 105. Here and in the following, recurring features are each provided with the same reference numerals. In the locked position, the first closing body 103 and the second closing body 105 interlock positively by means of the first locking elements 104a and 104b and by means of the second locking elements 106a and 106b. In particular, it can be seen in FIG. 2 that in the locked position the first locking elements 104a are connected to the second locking elements 104a

Locking elements 106a of the first closing element 114 and the first locking elements 104b with the second locking elements 106b of the second closing element 115 are engaged. The fact that the first closing body 103 and the second closing body 105 intermesh positively in the locked position by means of the first locking elements 104a and 104b and the second locking elements 106a and 106b is equivalent to the first closing body 103 and the second closing body 105 being in the Locked position can not be separated by a pure translation movement relative to each other.

In Fig. 2 is also clearly seen that the first closing element 114th and the second closing element 115 by means of further locking elements 139a of the first closing element 114 and by means of further locking elements 139b of the second closing element 115 permanently intermesh positively. Through this permanent positive connection between the first closing element 114 and the second closing element 115, these form the second closing body 105 as a structural unit. The further locking element 139a is formed as an annular recess on an inner side of the first closing element 114 designed as a hollow cylinder. Correspondingly, the further locking element 139b of the second closing element 115 is designed as a projection which extends annularly on an outer side of the second closing element 115. In this way, the first closing element 114 and the second closing element 115 can be rotated relative to each other about the second axis of rotation, which coincides with the first axis of rotation 111 in the locked position shown in FIG.

In the locked position of the first closing body 103 and the second closing body 105 shown in FIG. 2, the first closing body 103 surrounds the second closing body 105. This is equivalent to saying that the first closing body 103 comprises the second closing body 105, provided it is perpendicular to the z-direction is considered, at least partially, but preferably almost completely obscured, and further that the first closing body 103 and the second closing body 105 engage in a positive direction in any direction perpendicular to the z-axis. In the locked position shown in FIG. 2, the second closing body 105 closes the inner space 121 enclosed by the first closing body 103 to the upper side 119 of the first closing body 103. Nevertheless, the second closing body 105 is accessible in the locked position through the receiving opening 122 in the upper side 119 of the first closing body 103. Thus, it is possible to operate the first closing element 114 and the second closing element 115 in the locked position and to bring them back into the inserted position by rotation about the rotation axis 111 relative to the first closing body 103 from the locked position. In the unlocked position, the interlocking engagement of the first closing body 103 and the second closing body 105 is released by means of the first locking elements 104a and 104b and by means of the second locking elements 6a and 6b. In the locked position shown in FIG. 2, the first closing body 103 and the second closing body 105 enclose a space 107 that is a part of the inner space 121 enclosed by the first closing body 103. 2, the head 108 of the connecting element 102 is arranged in the space 107. In other words, the head 108, which is a part of the connecting member 102, is received in the locked position in the space 107.

Furthermore, it can be seen in FIG. 2 that the underside 120 of the closing body 103 is partially formed of exchangeable disk 103b. The retaining opening 123 is embedded in the disc 103b. One surface of the round disc 103b is smaller than a surface of the round receiving opening 122 in the upper surface 119 of the first closing body 103. Thus, it is possible to exchange the disc 103b through the receiving opening 122, so far as the second closing body 105 is from the first closing body 103 is spatially separated and the connecting element 102 is removed from the interior 121. Replacement of the disc 103b is advantageous because the area of the retaining opening 123 inserted into the disc 103b can thus be matched to the radius of the neck 152 of the connecting element 102 which is to be closed by the locking device 101. 2 further shows that a base body 103a of the first closing body 103 has, at a lower end of the main body 103a, a collar 124, which is made in one piece with the main body 103a, extends partially inwards towards the axis of rotation 111, and the disk 103b behind. Therefore, the disk 103b can not be removed in the negative Z direction. On the underside 120, therefore, the first closing body 103 forms an undercut which engages behind the space 107. While the head 108 of the connecting element 102 is received in the space 107, the neck 152 of the connecting element 102 engages through the retaining opening 123 in the underside 120 of the first closing body 103. The fact that the radius of the round head 108 is greater than the likewise round retaining opening 123, there is a positive connection between the locking device 101 and the connecting element 102 in the negative z-direction.

In the locked position shown in FIG. 2, the first closing position encloses Body 103 and the second closing body 105, the space 107 such that access to the space 107 is prevented from outside the closing device 101. In particular, the first closing body 103 and the second closing body 105 enclose the space 107 in the locked position such that it is not possible to access the head 108 of the connecting element 102 arranged in the space 107 with a tool. In the locked position, the occlusion device 101 has a length 109 of about 2.5 cm (see FIG. 3). A width 110 of the locking device 101 is also 2.5 cm (see FIG. 3). Due to the roughly cylindrical shape of the

Locking device 101 in the locked position is therefore also a

Height of the locking device 101 in the locked position in about 2.5 cm.

At the upper side 129 of the second closing element 115, this has a functional profile 153 (FIGS. 2 and 3 a) for engaging a tool 154, which is designed as an Allen key in FIG. In the locked position, the upper side 129 of the second closing element 115 faces the receiving opening 122 in the upper side 119 of the first closing body 103. Likewise, the functional profile may e.g. be designed as a slot for receiving a screwdriver. With a corresponding tool, the combination lock formed from the first closing body 103 and the second closing body 105 can be conveniently operated.

Between the underside 120 of the first closing body 103 and the second closing body 105, a spring 140 is arranged (FIG. 2). In the locked position, the spring 140 exerts a force directed onto the upper side 119 of the first closing body 103 on the second closing body 105. As a result, the second closing body 105 is arranged to be moved from the inner space 121 enclosed by the first closing body 103 in the positive z-direction as soon as the closing device 101 is brought from the locked position to the unlocked position.

Based on the Fign. 5a to 5d, a differential friction mechanism is shown, via which the first closing element 114, the second closing element 115 and the first closing body 103 are coupled to one another. This differential friction mechanism allows a particularly simple and convenient operation of the locking device 101. The differential friction mechanism is configured such that, for example, when rotating only the second closing element 115 clockwise relative to the first closing body 103, friction between the closing elements 103 and 105 is greater than friction between the first closing element 114 and the first one

Closing body 103 and as a friction between the second closing element 115 and the first closing body 103rd

As a consequence, when only the second closing element 115 is actuated in the clockwise direction relative to the first closing body 103, a simultaneous rotation of the first closing element 114 and the second closing element 115 takes place in the clockwise direction. In a first step, it is thus possible, by actuating the second closing element 115, e.g. by means of the Allen wrench 154 or by means of a screwdriver, the first closing element 114 are rotated to a desired position relative to the first closing body 103. The differential friction mechanism is further configured such that upon rotation of only the second closure member 115 in the counterclockwise direction relative to the first closure body 103, friction between the second closure member 115 rotated by direct actuation and the closure member 114 previously brought to the desired position is now smaller than that Friction between the already located in the desired position first closing element 114 and the first closing body 103. Thus, if a rotation of the second closing element 115 causes counterclockwise, so the second closing element 115 now rotates - unlike in the first step just described - alone. In this way, it is possible to bring the first closing element 114 and the second closing element 115 successively in the desired position relative to the first closing body 103. Both when locking and when unlocking the locking device 101, the differential friction mechanism configured in this way enables a particularly simple and user-friendly operation

Service.

This differential friction mechanism is realized in the locking device 101 in two ways. Thus, the friction between the first closing element 114 and the second closing element 115 by elevations

118 a (FIGS. 5 a and 5 b) on an inner side of the first closing element 114 and effected by recesses 118b (FIG. 5c) complementary to the elevations 1148a on an outer side of the second closing element 115. In Fig. 5b, which shows an xy-section along the line 155 in Fig. 2, the elevations 118a are shown engaged in the recesses 118b. For the sake of clarity, only two of the recesses 118b are indicated by arrows in FIG. 5b. FIG. 5b shows that the elevations 118a are formed by the second markings 117a designed as plastic pins, which for example extend beyond the inside of the first closing element 114 by 0.5 mm. The recesses 118b complementary to the elevations 118a on the outside of the second closing element 115 can be clearly seen in FIG. 5c.

Just as the second markings 117a formed as pins on the inside of the first closing element 114 facing the second closing element 114 form the elevations 118a, the same pins form elevations 141a (FIG. 5b) on an outside of the first closing element 114 facing the first closing body 103. Recesses 141b complementary to the elevations 141a on the inside of the first closing body 103 can also be seen in FIG. 5b and indicated by arrows. 5d it can be seen that the recesses 141b are incorporated in the first locking elements 104a. Referring to Figure 5b, there are 14 pads between the bumps 118a and the complementary recesses 118b, i. In contrast, there are only five contact points between the protrusions 141a and the corresponding recesses 141b, i. between the first closing element 114 and the first closing body 103. The second markings 117a of the first closing element 114 designed as pins thus effect, in connection with the recesses 118b of the second closing body 115 and in connection with the recesses 141b of the first closing body 103, the friction between The first closing element 114 and the second closing element 115 initially in both directions of rotation relative to the first closing body 103 is greater than the friction between the first closing element 114 and the first closing body 103.

Furthermore, the differential friction mechanism includes sawtooth protrusions 142a on an underside of the hollow cylinder first closing element 114 (FIG. 5a). FIG. 5 a further shows the second markings 117 a formed as pins, which on the one hand extend outward beyond the outside of the first closing element 114 and form the elevations 141 a. On the other hand, it is indicated in FIG. 5a that the second markings 117a likewise protrude beyond the inside of the closing element 114 and thus form the elevations 118a. Furthermore, the second locking elements 106a of the first locking element 114 are shown.

Fig. 5d shows schematically the first closing body 103 in an oblique view. On the inside of the first closing body 103 recesses 142b are shown, which form a counterpart to the sawtooth-like elevations 142a shown in FIG. 5a on the underside of the first closing element 114. The recesses 142 b are embedded in an upper side of a gallery-like projection 143, which extends in an annular manner along the inside of the first closing body 103. In the locked position or in the installed position, the first closing element 114 rests on the projection 143. A locking of the sawtooth-like elevations 142a in the recesses 142b has the result that the friction between the sawtooth-like elevations 142a on the underside of the first closing element 114 on the one hand and the recesses 142b on the upper surface of the projection 143, on the other hand, are largely different upon rotation of the first closure member 114 relative to the first closure body 103 for different rotational directions, respectively. Likewise, the sawtooth-like elevations 142b could be arranged laterally on the outside of the second closing body 105 or on the inside of the first closing body 103. It is crucial that in each case corresponding complementary counterparts exist on the respective other body, in which the sawtooth-like elevations can each engage at least partially, so that a relative rotational movement in one direction is prevented.

Together, the various friction functionalities described between the first closure element 114, the second closure element 115, and the first closure body 103 form the differential friction mechanism previously discussed.

The locking device 101 may have another security functionality that is not explicitly shown here. This security functionality however, in connection with the embodiment shown in FIGS. 7a to 9b illustrated closing arrangement and is in a simple manner to the

Locking device 101 transferable. These are profiles which, in the locked position of the locking device 101, are oriented preferably along the z-direction, ie. preferably perpendicular to the z

Direction arranged surfaces of the first locking elements 104a and / or 104b and / or the second locking elements 106a and / or 106b are arranged. By means of these profiles, the first locking elements 104a and / or 104b and / or the second locking elements 106a and / or 106b interlock positively as soon as a force between the first closing body 103 and the second closing body 105 is effective along the z-direction and is started, to rotate the closing bodies relative to one another. In this way, the rotation of the closing body is prevented relative to each other. Thus, it is not possible to simultaneously pull apart the closing bodies along the z-direction and to rotate relative to one another about the first rotation axis 111.

In the Fign. 6a and 6b, a closing device 201 which is slightly modified with respect to the closure device 101 is shown. The closing device 201 also includes a first closing body 203 and a second closing body 203

Closing body 205. Shown in FIGS. 6a and 6b, a connecting element 202 designed as a screw with a head 208, which, however, is not part of the closing device 201. The first closing body 203 and the second closing body 205 are each different from the connecting element 202. As well as the locking device 101 so is the

Locking device 201 formed almost entirely of stainless steel. A weight of the locking device 201 is about 100 g. The first closing body 203 has first locking elements 204a, 204b and 204c. These are only partially recognizable in FIG. 6a. In contrast, they are clearly shown in FIG. 6b.

The first locking elements 204a, 204b and 204c are formed as projections, which are not arranged on an inner side of the first closing body 203, but on an outer side of the closing body 203. From the outside, the first locking elements 204a, 204b and 204c each depend on a little less than 1 mm vertically. The first locking elements

204a, 204b and 204c and the first closing body 203 are made of the same first workpiece made of stainless steel.

The closing body 203 essentially has the shape of a hollow cylinder which has a receiving opening 222 on an upper side 219 and a retaining opening 223 on an underside 220. The first closing body 203 encloses a cylindrical inner space 221, which is adapted to receive the head 208 of the connecting element 202. The connecting element 202 can be inserted through the receiving opening 222 into the inner space 221. On a lower side 220 of the first closing body 203, this has a partially inwardly directed collar 224, which engages behind the interior 221 partially. The bottom 220 could also be partially formed as an exchangeable disc, in which the retaining opening 223 would then be embedded. Conveniently, the dimensions of the disc would be such that it can be easily exchanged through the receiving opening 222. The collar 224 would engage behind such a disk, so that the disk could not be removed from the interior 221 in the negative z-direction.

A construction of the second closing body 205 can be seen particularly clearly in FIG. 6a, which shows the closing device 201 in the closed position. The second closing body 205 comprises a first closing element 214, a second closing element 215 and a third closing element 230. The closing elements 214, 215 and 230 are each of annular design. By way of further locking elements 239a, 239b and 239c, the closing elements 214, 215 and 230 are each permanently in positive engagement with one another. They form a structural unit. The closing elements 214, 215 and 230 form a hollow cylinder, which, however, is closed off at an upper side 228 of the first closing element 214 by a cover 244. The lid 244 is fixedly connected to the first closure member 214, e.g. by a positive connection or by a material connection. For example, the lid 244 may be soldered to the first closure member 214. An outer radius 245 of the first closing body 203 is slightly smaller than an inner radius of the second closing body 205. The second closing body 205 is configured to at least partially enclose the first closing body 203.

The receiving opening 222 in the upper side 219 of the first closing body 203 is larger than the retaining opening 223 in the bottom 220 of the first closing body 203. The closing elements 214, 215 and 230 of the second closing body 205 each have on an inner side second locking elements 206a, 206b and 206c. Like the first locking elements 204a, 204b and 204c, the second locking elements 206a, 206b and 206c are also configured as projections on the inside of the second closing body 205, which is in part designed as a hollow cylinder.

The first closing body 203 and the second closing body 205 form a combination lock. In Fig. 6a, the first closing body 203 and the second closing body 205 are in a locked position. In the locked position, the first closing body 203 and the second closing body 205 engage in one another in a form-locking manner by means of the first locking elements 204a, 204b and 204c and by means of the second locking elements 206a, 206b and 206c. In the locked position, therefore, are pure translational movements of the first

Closing 203 prevented relative to the second closing body 205. This is to mean that centers of mass of the first closing body 203 and the second closing body 205 can not move in the locked position relative to each other. In the locked position, the locking device 201 has a height of 4 cm and a width and a length of 3 cm each.

The locking elements 214, 215 and 230 engage in such a permanent form-fitting manner with each other that they are always rotatable relative to each other about their common axis of symmetry. In Fig. 6a, the common axis of symmetry of

Closing elements 214, 215 and 230 with an axis of symmetry of the first closing body 203 together. This in the locked position shown in FIG. 6a common axis of symmetry of the first closing body 203 and the second closing body 205 is a first axis of rotation 211 of

Locking device 201.

The first locking elements 204a, 204b and 204c and the second locking elements 206a, 206b and 206c are arranged on the outside of the first closing body 203 and on the inside of the second closing body 205, that in the locked position by means of the locking elements between the first closing body 203 and the second closing body 205 existing positive connection by rotation of the closing elements 214, 215 and 230 relative to the first closing body 203 can be canceled. A position in which the second closing body 205 surrounds the first closing body 203, but the positive locking between the first locking elements 204a, 204b and 204c and the second locking elements 206a, 206b and 206c is canceled, is a recessed position. The recessed position is an unlocked position. If the first closing body 203 and the second closing body 205 are in the inserted position, they can be spatially separated from each other, in that the second closing body 205 moves in a positive translation relative to the first closing body 203 in a positive translation.

Direction 235 executes. Also, a position in which the first closing body 203 and the second closing body 205 are spatially separated is an unlocked position of the locking device 201. By changing a relative arrangement to each other, the first closing body 203 and the second closing body 205 can be unlocked from the locked position Position and be brought from the unlocked position to the locked position.

In the locked position shown in FIG. 6a, the first closing body 203 and the second closing body 205 enclose the inner space 221 in such a way that access to the space is prevented by means of a tool, such as an Allen wrench or a screwdriver. In FIG. 6a, the inner space 221, which is enclosed by the first closing body 203 and which is closed off at the upper side 219 by the cover 244 of the second closing body 205, receives the head 208 of the connecting element 202. By means of the collar 224, at the bottom 220 of the first

Closing body 203 is arranged and extends inwardly from a cylindrical side wall of the first closing body 203 to the first axis of rotation 211, the first closing body 203 engages behind the inner space 221. This means that the first closing body 203, the enclosed by him interior 221 at the bottom 220th undercut by means of the inwardly projecting collar 224.

A radius of the retaining opening 223 on the underside 220 of the first closing body 203 is greater than a radius of a neck of the connecting element 202, but smaller than a radius of the head 208 of the connecting element

202. In this way, the locking device 201 is set up, the Bonding element 202 and its head 208 engage behind positively. If the head 208 of the connecting element 202 is received in the inner space 221 as shown in FIG. 6a and the locking device 201 is in the locked position, access to the space 221 which engages behind the head 208 is not possible.

On an outer side of the closing elements 214, 215 and 230, respectively, second markings 217a, 217b and 217c are arranged. The second markings 217a, 217b and 217c are each formed as elastic marking rings made of plastic. Along a circumference of the marking rings letters are engraved in the marking rings at regular intervals. The closing elements 214, 215 and 230 have grooves extending in each case in the z-direction 235 on an outer side facing the second markings 217a, 217b and 217c. Corresponding grooves 256a on the outside of the first closing element 214 can be seen partially in FIG. 6a.

The respective grooves of the closure members 215 and 230 are concealed in Fig. 6a respectively by the second markings 217b and 217c. The second markings 217a, 217b and 217c have, on an inner side facing the closing elements 214, 215 and 230, complementary projections to the grooves, which likewise run along the z-direction in the locked position shown in FIG. 6a.

By means of the grooves on the outer sides of the closing elements 214, 215 and 230 and the bulges on the inner sides of the second markings 217a, 217b and 217c complementary to the grooves, the closing elements and the respective marking rings assigned to them engage in a form-fitting manner. A clamping ring 247 arranged at a lower end of the closing element 230 is in form-locking engagement with the third closing element 230 and prevents, in the locked position shown in FIG. 6a, the marking ring arranged on the closing element 230 in the negative z-direction from the closing element 230 stripped who can. By applying a small force, the clamping ring 247 can be separated from the third closing element 230. However, this is usually only possible if the first closing body 203 and the second closing body 205 are in the unlocked position and are spatially separated from each other. If the clamping ring 247 is removed from the third closing element 230 Thus, the marking rings formed second marks 217c, 217b and 217a can be successively stripped from the annular closure members 230, 215 and 214 on which they are respectively arranged. This is facilitated in an advantageous manner in that the grooves on the outer sides of the closing elements 214, 215 and 230 as well as the protuberances complementary to the grooves on the insides of the marking rings each extend along the z-direction. In the unlocked position, the marking rings can thus be stripped off the closing elements 214, 215 and 230 and, in a modified arrangement relative to the closing elements 230, 215 and 214, re-wound onto the closing elements 230, 215 and 214. In this way, it is possible to change a letter combination indicating the unlocked position at will. A security of the locking device 201 is thereby increased in an advantageous manner. First markings 216 on the first closing body 203 are arranged concealed in FIG. 6a on the underside 220 of the closing body 203. A relative orientation of the second markers 217a, 217b and 217c to the first marks 216 marks the unlocked position of the first closing body 203 and the second closing body 205.

The occlusion device 201 may also be oriented on, preferably, the z-directional direction. preferably perpendicular to the z-directional surfaces of the first locking elements 204a, 204b and 204c and / or on corresponding surfaces of the second locking elements 206a, 206b and 206c profiles, by means of which the first locking elements 204a, 204b and 204c and the second locking elements 206a, 206b and 206c form-fitting into one another, as soon as along the z-direction, a force between the first closing body 203 and the second closing body 205 is effective. In this way, a rotation of the closing body is prevented relative to each other. Thus, it is not possible to simultaneously pull apart the closing bodies along the z-direction and to rotate relative to each other about the first rotation axis 211. The configuration of these profiles will be explained with reference to the closing arrangement 301 described below. It can be easily transferred to the locking device 201.

Fig. 7a shows a closing arrangement 301. The closing arrangement 301 comprises a closing device, wherein the closing device in turn a first closing body 303 and a second closing body 305. The closing arrangement 301 also includes a connecting element, which is formed integrally with the closing body 303. In other words, the closing body 303 and the connecting element in the closing arrangement 301 are identical. In this particular embodiment of the invention, therefore, the connecting element, given here by the closing body 303, part of the claimed invention. In the present case, the connecting element or the closing body 303 is designed as a nut. In its function as a nut, the first closing body 303 encloses a downwardly open cavity 348, which has a thread 349 at a lower end. A lower portion of the closing body 303 forms a functional part 350. The functional part 350 can be seen more clearly in FIG. In the present case, the functional part 350 is designed as a regular hexagon. In this way, the first closing body 303 can be actuated by means of a hexagonal wrench acting on the functional part 350. The first closing body 303 is approximately cylindrically symmetric, has a height of about 2.5 cm and a radius of slightly less than 1 cm. On an outer side, the first closing body 303 has first locking elements 304a, 304b and 304c, which are formed as projections and protrude in a direction perpendicular to a cylinder axis of the first closing body in each case by approximately 1 mm from the first closing body 303 to the outside. An arrangement of the first closing elements 304a, 304b and 304c on the first closing body 303 can be seen particularly well in FIG. The first closing body 303 and the first locking elements 304a, 304b and

304c are formed of a stainless steel workpiece. The second closing body 305 comprises a first closing element 314, a second closing element 315 and a third closing element 330, wherein the closing elements 314, 315 and 330 are each of annular design. A part of the second closing body 305 also forms a flange 347. By means of further locking elements 339a, 339b, 339c and 339d are the closing elements 314, 315, 330 and the flange 347 in a permanent positive engagement with each other, thereby forming a structural unit , In particular, the second closing body 305 comprising the closing elements 314, 315 and 330 has the shape of a partially closed at an upper side 328 of the first closing element 314 by a cover 344 and at an underside 356 of the second closing body 305 open hollow cylinder. The cover 344 is permanently connected to the first closing element, for example by a material connection or a non-releasable positive connection. The second closing body 305 thus encloses an approximately cylindrical cavity 307, which is almost completely filled by the first closing body 303 here. The closing elements 314, 315 and 330 have on an inner side in each case second locking elements 306a, 306b and 306c which, with the closing elements, are each formed from the same workpiece made of stainless steel. The second locking elements 306a, 306b and 306c are formed as projections, each of which protrudes slightly less than 1 mm perpendicularly from the closing elements 314, 315 and 330 and project into the cavity 307 formed by the second closing body 305.

The closing elements 314, 315 and 330 are each rotatable relative to each other about a second axis of rotation, wherein the second axis of rotation in the FIG.

7a coincides with the cylinder axis of the first closing body 303. Together, the first closing body 303 with the first locking elements 304a, 304b and 304c and the second closing body 305 with the second locking elements 306a, 306b and 306c form a combination lock. In particular, the second closing body 305 is set up to enclose the first closing body 303 designed as a nut in the present case. The approximately cylindrically shaped first closing body 303 has a shape complementary to that formed as a hollow cylinder second closing body 305. The first closing body 303 is thus set up to be let into the cavity 307 surrounded by the second closing body 305.

In Fig. 7a, the closing device formed from the first closing body 303 and the second closing body 305 is in a locked position. In this locked position, the first closing body 303 and the second closing body 305 engage by means of the first locking elements 304a,

304b and 304c and by means of the second locking elements 306a, 306b and 306c positively into one another. In the locked position, therefore, a center of gravity of the first closing body 303 and a center of mass of the second closing body 305 can not be moved or are hardly moved relative to each other. By corresponding rotation of the closing elements 314, 315 and 330 relative to the first closing body 303 about a first axis of rotation 311, which coincides in the locked position shown in Fig. 7a with the cylinder axis of the first closing body 303 and the second axis of rotation of the second closing body 305 can the locking device formed from the first closing body 303 and the second closing body 305 are brought from the locked position to an unlocked position. In the unlocked position, the positive locking engagement of the first closing body 303 and the second closing body 305 effected by means of the first locking elements 304a, 304b and 304c and by means of the second locking elements 306a, 306b and 306c is released, so that the first closing body 303 and the second closing body 305 can be spatially separated by a pure relative translational movement along the first axis of rotation 311. For this purpose, the first closing body can be removed from the cavity 307 through an opening arranged on the underside 356 of the second closing body 305.

In the locked position of the first closing body 303 and of the second closing body 305 shown in FIG. 7 a, the second closing body 305 engages behind the cavity 307, in which the first closing body 305 is received, by means of the second locking elements 306 a, 306 b and 306 c. In other words, the second closing body 305 in the locked position engages with the second locking elements 306a, 306b and 306c the space occupied directly by the first closing body 303 and the first locking elements 304a, 304b and 304c, which is a part of the cavity 307. Because of the interlocking of the first locking elements 304a, 304b and 304c and the second locking elements 306a, 306b and 306c, therefore, the first closing body 303 and the second closing body 305 can not be spatially separated in the locked position by a mere relative translational movement. In particular, the second closing body 305 configured as a hollow cylinder encloses the cavity 307 such that access to the closing body 303, but in particular to the functional part 350 of the first closing body 303 in the locked position, is prevented. In the locked position, it is thus not possible, in particular, to actuate the first closing body 303 designed as a nut by means of a tool, such as a hexagon wrench, for example. This way is in the Locked position prevents unauthorized access to the connecting element designed as a first closing body 303.

The closing arrangement 301, which comprises the first closing body 303 and the second closing body 305 because of the one-part construction of the first closing body 303 and of the connecting element

Closing device is identical, has a weight of about 100 g. In the locked position shown in Fig. 7a, a length of the latch assembly 301 in the locked position is about 3 cm. A width and a height of the closing arrangement 301 are each slightly more than 2 cm in the locked position.

It can be seen in FIG. 7b that second markings 317a, 317b and 317c are respectively arranged on an outer side of the closing elements 314, 315 and 330. The second marks 317a, 317b and 317c are each formed as plastic elastic marking rings. Along a circumference of the marking rings letters are engraved in the marking rings at regular intervals. The closing elements 314, 315 and 330 have grooves extending in each case in the z-direction 335 on an outer side facing the second markings 317a, 317b and 317c. The second markings 317a, 317b and 317c have, on an inner side facing the closing elements 314, 315 and 330, protuberances that are complementary to the grooves and also run along the z-direction 335 in the locked position shown in FIG. 7b. The first closing body 303 likewise has a first marking 316, which is partially defined by the

Lid 344 protrudes and is formed as a recess. Relative orientation of the second marks 317a, 317b, and 317c to the first marker 316 indicates the unlocked position of the first marker 316

Closing device 301. If the first closing body 303 and the second closing body 305 are spatially separated, the second markings 317a, 317b and 317c can be brought into a changed position relative to the closing elements 314, 315 and 330, respectively, by moving along the grooves first deducted from the closing elements 314, 315 and 330 and then reared in the changed position again on the closing elements 314, 315 and 330. For this purpose, however, first the

Flange 347 are removed with the lower closure member 330 in interlocking engagement and prevents removal of the second markings 317a, 317b and 317c prevented. If the first closing body 303 and the second closing body 305 are spatially separated, the flange 347 can be detached from the lower closing element 330 with little force.

A special functionality to increase the security of the first closing body 303 and the second closing body 305 comprehensive

Locking device will be described below with reference to FIGS. 9a and 9b illustrates. This functionality is easy on the

Locking devices 101 and 201 transferable. 9a shows a section through the second closing body 305. The second locking elements 306a, 306b and 306c can be seen clearly, each of which protrudes by about 1 mm into the approximately cylindrical cavity 307, which is enclosed by the second closing body 305. The second locking elements 306a, 306b and 306c in each case form annular and interrupted by recesses

Structures which respectively circulate on inner sides of the annular closing elements 314, 315 and 330 and are arranged approximately symmetrically with respect to the second rotational axis of the second closing body 305. On surfaces 312a, 312b and 312c of the second locking elements 306a, 306b and 306c, profiles 313a, 313b and 313c are respectively introduced. The surfaces 312a, 312b, and 312c of the second locking elements 306a, 306b, and 306c are aligned along the cylinder axis of the second closing body 305, respectively. In particular, the surfaces 312a, 312b and 312c are perpendicular to the cylinder axis of the second closing body 305, i. on the second rotational axis of the two closing body 305.

The profiles 313a, 313b and 313c, which are embedded in the surfaces 312a, 312b and 312c and disposed on the surfaces 312a, 312b and 312c, are formed in the form of protrusions and recesses, each having a height or depth of about one have half a millimeter. The profiles

313a, 313b, and 313c are complementary to the first latch members 304a, 304b, and 304c, not shown in FIG. 9a, such that the first latch members 304a, 304b, and 304c are configured to latch into the profiles 313a, 313b, and 313c. Now are the first closing body 303 and the second closing body 305 in the locked position and is on the first closing body 303 and on the second closing body 305 respectively a train is applied, which aims to spatially separate the first closing body 303 and the second closing body 305 by a relative translational movement along the first axis of rotation 311 and at the same time, for example, the first closing element 314 is rotated relative to the first closing body 303, so snap the first closing elements 304a of the first closing body 303 into the corresponding profiles 313a on the surfaces 312a of the second locking elements 306a, so that further rotation of the first closing element 314 relative to the first closing body 303 is prevented. The profiles 313a, 313b and 313c, which are arranged on the surfaces 312a, 312b and 312c aligned along the cylinder axis of the second closing body 305, in this case thus cause the first locking elements 304a, 304b and 304c to engage in a form-locking manner with the second locking elements 306a, 306b and 306c and with the profiles 313a, 313b and 313c intermesh. FIG. 9b shows an xy-section through the closing arrangement shown in FIG. 7a

301, along a section plane 351 indicated in FIG. 7 a, which is perpendicular to the cylinder axis of the second closing body 305. The closing body 303 with the locking elements 304a and the profiles 313a on or in the surfaces 312a of the second locking elements 306a shown in FIG. 7a can be seen in FIG. 9b. It can be seen that the profiles 313a of the first closing element 314 reach into the cavity 307 enclosed by the second closing body 305 by approximately half a millimeter. The profiles 313 a form a regular coronary structure arranged along an inner side of the first closing element 314. The profiles 313a form projections at regular intervals and recesses arranged between the projections. It is clearly visible that the recesses each have a complementary to the first locking elements 304a structure. In FIG. 9 b, the first locking elements 304 a are respectively engaged in the profiles 313 a, so that rotation of the first locking element 314 relative to the first closing body 303 is prevented.

Of course, the profiles 313a, 313b, and 313c shown herein with respect to the latch assembly 301 may also be used in conjunction with the previously described shutters 101 and 201. This means that e.g. also the first locking elements 104a in FIG.

1 profiles of the type described here may have. The same applies to the first latch members 204a, 204b and 204c as well as the second latch members 206a, 206b and 206c shown in Fig. 6a.

The Fign. 10 to 12 show the closing arrangement 301 as part of a quick-release device 401 of a bicycle, not shown here. For this purpose, designed as a mother first closing body 303 is screwed onto a wheel axle 434 of the bicycle and firmly connected to the wheel axle 434. However, the wheel axle 434, which is a front axle, is not itself part of the quick release device 401. However, part of the quick release device is a third body 431 and a cam 433 eccentrically mounted on a shaft 432. The shaft 432 and the cam 433 are made of stainless steel and made of a workpiece. For actuating the shaft 432, a lever 457 is additionally arranged on the latter, by means of which a torque can be transmitted to the shaft 432. The shaft 432 with the cam 433 and the lever 457 are shown separately in FIG.

The quick-release device 401 is arranged on the wheel axle 434. The third body 431 encloses the wheel axle 434 so that it is positively connected to the wheel axle 434 in a direction perpendicular to the wheel axle 434. However, the third body 431 is not fixedly connected to the wheel axle 434 so as to be movably disposed along the wheel axle 434. The third body 434 is also formed of stainless steel and has a cylindrically symmetrical shape with a height of about one centimeter and a radius of about two centimeters. At a bottom 458, the third body 431 is substantially planar. The third body 431 is adapted to be pressed against a fork of the bicycle, not shown here, and in this way to firmly connect the wheel axle 434, together with a rim rigidly connected to the wheel axle 434, not shown here, to the fork, i. to stretch.

The shaft 432 is positively connected to the third body 431, for example, the shaft 432 engages through a hole in an outside of the partially hollow third body 431 in the third body, wherein the cam 433 is surrounded by the third body 431, ie within the third body 431 is arranged. The shaft 432 is rotatably disposed in the hole in the outside of the third body 431, so that the cam 433 can be moved by means of the lever 457. The cam 433 is arranged between the underside 458 of the third body 431 and the first closing body 303 of the closing arrangement 301. Fig. 10 shows the quick release device 401 in a cocked position.

In this case, the cam 433 bears against the closing body 303 fixedly connected to the rear axle 434, with a cam end 459 which forms an end of the cam 433 which is furthest away from an axis of rotation of the shaft 432. Due to the fact that the shaft 432 positively engages the third body 431, the third body 431 is held by the abutment of the cam end 459 on the first closing body 303 at a maximum distance from the first closing body 303 and against the fork of the Bicycle pressed so that the wheel axle 434 is tensioned. In FIG. 10, the closing arrangement 301 is in the locked position, wherein the underside 356 of the second closing body 305 bears against the third body 431. By the positive engagement between the first closing body 303 and the second closing body 305 in the locked position, the second closing body 305 acts as a spacer between see the first closing body 303 and the third body 431. Is the quick-release device 401 in the cocked position and is the locking assembly 301 is brought into the locked position, as shown in Fig. 10, the quick-release device 401 due to the action of the second closing body 305 as a spacer between the first closing body 303 and the third body 431 also by operating the cam 433 by means of the lever 457th not be moved from the cocked position to a non-cocked position. Thus, the locking assembly 301 prevents theft of the wheel axle 434 and arranged on the wheel axle 434 rim.

The Fign. IIa and IIb show the quick-release device 401 in the unlocked position of the closure assembly 301, wherein the second closure member 305 is spatially separated from the first closure member 303 and not shown. If the closing arrangement 301 is in the unlocked position, the distance between the first closing body 303 and the third

Body 431 are controlled by means of the cam 433. In the Fign. IIa and IIb, this is recognizable by the fact that a distance (indicated in the figures IIa and IIb respectively by dashed lines) between an underside 320 of the first closing body 303 and the third body 431 depends on an arrangement of the cam end 459 of the cam 433. The different arrangements of the cam 433 are each accompanied by a different position of the lever 457.

It should be emphasized that also slightly modified embodiments of the closing arrangement 301 can be used as part of a quick-release device. In particular, it is not necessary for the first closing body 303 on the upper side 319 to be closed. Both the first closing body 303 and the second closing body 305 can be completely formed as a hollow cylinder. So they can be pushed arbitrarily far on the wheel axle 434. It is crucial in each case that an unauthorized person can not detach the first closing body 303 in the locked position of the closing arrangement 301 from the wheel axle 434 and that the second closing body 305 in the locked position acts as a spacer between the first closing body 303 and the third body 431, so that the unauthorized person can not bring the quick release device 401 in the untensioned position.
