Description

Technical area

The present invention relates to a pick-up system for picking up and collecting objects / elements to be collectivized (e.g. keys, tools and correspondingly suitable objects), comprising a pick-up unit for collecting objects and an innovative locking unit that allows objects to be securely picked up in the pick-up unit guaranteed and at the same time enables unhindered and quick removal of the objects from the receiving system. The invention also includes a method for its production.

State of the art

A large number of receiving systems for objects are known from the prior art or are already used in everyday life.

For example, metal rings are known, in which a wire is arranged in a circular manner and spans an arc of more than 360 °, ie usually at least 420 °, whereby an elastic spiral is formed, the ends of the wire being formed so that they are positively attached to one another, so that undesired loosening the objects collectivized with it, in particular of keys, is prevented.

Furthermore, so-called hinged metal rings are known, which are formed from at least two wire elements (for example, semicircular). These wire elements are connected to one another at one end via a hinge and thereby form a ring, the ring being able to be temporarily opened or closed by the wire elements at their respective free ends via a locking means (e.g. a barb) and thereby picking up and removing of objects to be collectivized allowed.

Furthermore, receiving systems are known which, similar to the aforementioned metal ring, are also designed in two parts, a first part of the receiving system forming a receiving area for objects to be collectivized and a second part being mostly inseparably coupled to the first part via one end and via a second end (which is in the form of an eyelet, for example) is separably coupled to the end of the first part (which is in the form of a hook, for example).

Another example of a receiving system is a flexible wire, the ends of which can be coupled to one another in a separable manner by means of a screw connection and thus secure the objects being received.

In addition, snap hooks are also known, the snap hook being formed from a hook with a spring-assisted snap lock.

From the German utility model DE 20 2013 008 833 U1 a locking unit made of wire or wire-shaped material for holding keys and correspondingly suitable objects is known, which consists of a storage area and a locking system, characterized in that the latter is formed by the wire ends which are shaped such that they are starting from the storage area , turn around each other in such a way that in the closed state, due to a tension, they lie on top of each other at least at one point so that no objects can be brought in and out and in the open state they are so far apart or there is so little tension between them that objects can be introduced and carried out, whereby a change from one to the other state requires an exertion of force in which the position of the wire ends is changed to one another.

The disadvantage of the known pick-up systems, particularly in the case of metal rings, is, on the one hand, the complex process for picking up and removing the objects to be collectivized.

When using a metal ring, for example, in which the ends of the wire are arranged in an overlapping and form-fitting manner, the ends of the wire must be laboriously bent up against each other and the ends must be clamped against each other during the process of picking and removing by applying pressure. This is mostly done by applying pressure to the object to be collectivized, which can deform or damage it.

A further disadvantage of the previously known receiving systems is that, in the event that a large number of objects are arranged in the receiving unit, this large number of objects makes it difficult to remove individual objects, since this prevents the necessary opening, for example by pressing the ring on (in particular by a unwanted holding together of the ring).

In addition, in particular in the case of a (open) hinged receiving system, the locking unit is not separately secured, so that, during normal use, the locking unit can mostly be opened unintentionally, for example by popping open, with collectivized Objects can be detached from the receiving unit.

However, the attachment of a securing unit, which is intended to prevent the locking unit from unintentionally popping open, is cost-intensive to produce.

Ultimately, the known receiving systems are limited to a specific design, the receiving area mostly being circular.

Due to the disadvantages of known approaches, the present invention is therefore based on the object of creating a cost-effective and flexible receiving system for objects that (1) on the one hand allows multiple objects to be received in a confined space, (2) at the same time ensures simple and fast operation that allows objects to be picked up and removed easily and (3) at the same time maintains a high level of security for the lock.

According to the invention, this object is achieved by providing a device, preferably an in particular one-piece receiving system, for receiving objects to be collectivized according to claim 1.

Further advantageous refinements are given in the subclaims.

1. a) ein Teil des Drahtelementes als Aufnahmeeinheit (2) ausgebildet ist,
2. b) die Enden des Drahtelementes (4, 4') als Verschlusseinheit (3) ausgebildet sind, wobei die Verschlusseinheit (3) unmittelbar an die Aufnahmeeinheit (2) angeordnet ist,

wobei zumindest ein Ende des Drahtelementes (4') bogenförmig ausgestaltet ist (5),
wobei die Enden des Drahtelementes derart ausgestaltet sind, dass diese bei einer Spannbelastung relativ zur Aufnahmeeinheit (2) ineinandergreifen und gegeneinander verschränkt werden können, wodurch die Verschlusseinheit (3) in einen geschlossenen Zustand überführt wird.The device according to the invention for picking up objects to be collectivized comprises an element ( 1 ) made of wire, wire-like material ( 1 ) or another material with non-zero elasticities (ie a material that exhibits flexibility or that is elastically deformable), with at least one first end ( 4 ' ) and a second end ( 4th ), preferably a one-piece, continuous wire element ( 1 ), in which

1. a) part of the wire element as a receiving unit ( 2 ) is trained,
2. b) the ends of the wire element ( 4th , 4 ' ) as a locking unit ( 3 ) are formed, the locking unit ( 3 ) directly to the recording unit ( 2 ) is arranged,

where at least one end of the wire element ( 4 ' ) is arcuate (5),
whereby the ends of the wire element are designed in such a way that they are exposed to a tension load relative to the receiving unit ( 2 ) can interlock and interlock, whereby the locking unit ( 3 ) is brought into a closed state.

The term "arched" means in the sense of the present invention that the first end ( 4 ' ) is angled at one or more points in relation to the plane of the wire-like material essentially to obtain a bulge (preferably an arched shape), wherein in particular the first end can be angled at two points in opposite directions, so that an effective s or z -like shape is created.

The acquisition unit ( 2 ) is formed in that the opposite ends of the wire element ( 4th , 4 ' ) in at least one area of the wire ends contacting or non-contacting relative to one another (with the formation of a recess ( 7th )) are merged. Preferably the ends of the wire element ( 4th , 4 ' ) contacting or with a narrow recess ( 7th ) merged relative to each other. This prevents the objects (elements) to be collectivized from being unintentionally or uncontrolled out of the receiving unit when the device is open ( 2 ) can slide out. The recording unit is preferably ( 2 ) formed by the central area of the wire element as a ring or ring-like structure.

In this case, at least one end of the wire element points in the open state of the device at a point (so-called bending point), which the receiving unit ( 2 ) is downstream, one is directly attached to the recording unit ( 2 ) subsequent bend, so that at least a first area of this wire end, which is directly attached to the receiving unit ( 2 ) is arranged, or a second region of this wire end, which is arranged downstream of the bending point, has a contact-free spacing relative to the other end of the wire element.

With the pick-up system, in which the wire ends, which are positioned relative to the pick-up unit ( 2 ) can be interlaced against each other, a simple and quickly reclosable locking mechanism is provided, which enables the objects to be removed / picked up quickly and without hindrance from or into the receiving system and also ensures a high degree of locking security.

Since the wire is not laid twice, as is the case with conventional key rings, it can be made larger. This makes it possible to round off the wire ends sufficiently using cost-effective technical processes (e.g. vibratory grinding), which means that damage to objects to be collectivized and damage to the "environment" (e.g. skin, clothing) is less likely.

In a simple embodiment, the receiving system consists of a continuous, preferably one-piece wire element. The receiving system can also be made up of several components, the individual components being connected to one another, for example, by joints or by a hook / eye mechanism.

In a preferred embodiment of the present invention, the receiving system is designed in one piece. That is to say, the receiving system consists of a continuous, preferably one-piece, wire element. In this case the locking unit ( 3 ) directly into the receiving unit ( 2 ) above.

Ideally the recording unit ( 2 ) when the locking unit is open ( 3 ) (ie without tensioning the two ends of the wire relative to each other) at least semicircular and forms a circular arc section between 180 ° and 360 °, that is, the ends of the wire element ( 4th , 4 ' ) are brought together contact-free relative to one another in at least one area of the wire ends. This ensures that the objects to be collectivized are exposed to little or no pressure during the process of picking up and removing, in contrast to known pick-up systems, whereby deformation or any other type of damage to the objects to be collectivized can be prevented.

Basically, the tension load on the ends of the wire element in the closed state ensures that unintentional opening of the locking unit ( 3 ) (e.g. by the ends of the wire elements jumping open) is prevented.

In order to further minimize the likelihood of unintentional opening, a separate safety unit ( 6th ) (e.g. an eyelet, a locking cap or a locking ring, which the locking unit ( 3 ) at least partially circulate) be provided, which prevent unintentional opening of the locking unit ( 3 ) when closed - as a result of the wire ends springing open relative to the receiving unit ( 2 ) are entangled against each other - prevented by an external force.

In a specific embodiment, the backup unit ( 6th ) be designed as a closure cap, which the closure unit ( 3 ) encloses in the form of a jacket, thereby further reducing the risk of living beings and objects being injured or damaged, for example by pressure points.

The amount of friction which the receiving unit ( 2 ) elements to be picked up or removed when the device is open is directly proportional to the normal force with which the first end of the wire element ( 4 ' ) against the second end of the wire element ( 4th ) presses. This normal force is repeated each time the elements to be collectivized are picked up or removed. As the normal force increases, the risk of the elements to be collectivized being deformed at their contact points (contact points) to the ends of the wire element or experiencing another type of damage increases. In order to optimize the service life of the elements to be collectivized, but also of the device according to the invention, it is desirable to reduce the pressure of the elements to be collectivized at the ends of the wire element ( 4th , 4 ' ) to limit. It can therefore be provided that the recording unit ( 2 ) in the open state of the device according to the invention a recess ( 7th ) (i.e. that in the open state of the receiving unit ( 2 ) a space between the ends of the wire element ( 4th , 4 ' ), whereby the picking up and removal of elements (objects) to be collectivized is facilitated with little or no effect of a normal force.

The bending of the two ends of the wire element ( 4th , 4 ' ), which are attached directly to the acquisition unit ( 2 ), or the bend of the receiving unit can be selected in such a way that the degree of the recess can be adjusted as required.

Detailed definition of the invention

The receiving system preferably has a curved wire element, that is produced by a bending forming process or produced by a primary forming process (e.g. by casting metal in a corresponding mold), continuous wire element ( 1 ) on.

The continuous wire element can be made of iron, copper or an alloy, e.g. steel (spring steel), brass or surface-refined starting materials (e.g. gold-plated or silver-plated materials). The wire element, which is referred to simply as a wire element in the following, can actually be designed as a wire element in the narrower sense.

But it can also be an element made of wire-like material. It can also be a different material which has a certain elasticity. An elastic material strives to return to its original shape under deformation. Due to the elasticity, the Device can be closed particularly securely, can be opened securely, can safely remain in an open state. This makes the receiving device very convenient to use, very safe and no collectivized objects, such as keys, are accidentally lost.

The device is preferably designed in such a way that the first end ( 4 ' ) and the second end ( 4th ) have and hold positive contact in the closed state, which can be achieved in particular that the first end in a first portion of the first end with at least a first portion of the second end is in contact or pressure contact, and the first end in a second portion of the first end with at least a second portion of the second end maintains contact or pressure contact, the contact or pressure contact in the second portion of the second end and the contact or pressure contact in the first portion of the second end in substantially the same directions, so that the second end is effective on both sides is bounded and / or clamped in a form-fitting manner by the first end.

The device according to the invention is characterized in that it has a first open state in addition to the closed state. In this case, the device can be transferred to the first open state by an external force, the device being designed in such a way that this open state is then maintained without the action of external force (ie stress-free). This is achieved, for example, in that the recording unit ( 2 ) in the open state of the device (i.e. without tension on the two ends of the wire relative to one another) - as described above - is at least semicircular or forms a circular arc section between 180 ° and 360 ° (i.e. the receiving unit ( 2 ) is designed as a circumferential arc with less than 360 ° in the open state).

It can be provided that, in addition to the closed state, the device has a second open state which is different from the first open state.

Here, too, it is provided that the device can be transferred to the second open state by an external force and is able to maintain this state afterwards without the action of external force.

It has been shown that it is of great advantage that at least one of the ends is designed to be at least partially free-standing when the device is in an open state. This allows the objects to be collectivized to be exposed to little or no pressure during the process of picking up and removing, in contrast to known pick-up systems, whereby deformation or any other type of damage to the objects to be collectivized can be prevented.

The first end of the device is preferably designed to be at least partially free-standing when the device is in the first open state.

In contrast, the second end of the device does not have to be designed to be free-standing when the device is in the first open state.

Advantageously, the device enables a direct change of state between the closed and the first open state, as well as a direct change of state between the closed and the second open state, whereby the device does not change the state between the first and second open state directly, but only indirectly via the closed state enables.

It can also be provided that the second end is designed to be essentially flat in the plane of the wire-like material, while the first end is essentially angled at one or more points in relation to the plane of the wire-like material, with the first end in particular at two spots can be angled in opposite directions to create an effective s- or z-like shape.

According to a further development, the ends of the wire element in the closed state point essentially parallel in a common direction, wherein in particular a loop-shaped topological arrangement of the wire element can arise (so-called “loop variant”). In this variant, the device is extremely easy to open and close. The locking mechanism is attached in a well-defined direction and is easy to locate.

According to a further development, the ends of the wire element in the closed state point essentially anti-parallel in opposite directions, whereby in particular a ring-shaped topological arrangement of the wire element can arise and in particular the ends of the wire element essentially continue the topologically ring-shaped course of the wire element (so-called "ring variant "). In this variant, the locking mechanism forms a harmonious part of the ring. The arrangement is very compact and the risk of injury is reduced.

According to a further development, the first and second ends have and maintain form-fitting contact in the closed state, which can be achieved in particular in that the first end maintains contact or pressure contact in a first sub-area of the first end with at least a first sub-area of the second end, and that The first end in a second sub-area of the first end maintains contact or pressure contact with at least a second sub-area of the second end, the contact or pressure contact in the second sub-area of the second end and the contact or pressure contact in the first sub-area of the second end taking place in substantially the same directions so that the second end is effectively bounded and / or clamped in a form-fitting manner on both sides by the first end. This arrangement means that the ends are interlaced in a space-saving manner. The elasticity is used to generate pressure contact which can hold the device in the open or closed state. This will keep the desired state. This also increases the safety of the device.

According to a further development, in addition to the closed state, the device has a first open state. In the open state, for example, elements to be collectivized can be added or removed.

According to a further development, the device can be transferred to the first open state by an external force (i.e. by exerting a rotational movement of the first and the second end relative to one another) and is then able to maintain this state without the action of an external force. This is very convenient when the user wants to add or remove items to be collectivized.

According to a further development, in addition to the closed state and the first open state, the device has a second open state which is different from the first open state. This gives the user two options for opening the device. Depending on how the collectivized elements are arranged in the recording system, he can opt for the simpler option. In one example, the user can thus choose one of the ends of the wire element and make the selection of the end by selecting the first or second open state.

According to a further development, the device can be transferred to the second open state by an external force and is then able to maintain this state without the action of an external force. As with the first state, this is very convenient if the user wants to add or remove elements to be collectivized.

According to a further development, at least one of the ends is designed to be at least partially free-standing when the device is in an open state. As a result, elements to be collectivized can be added particularly easily. In one example, it is also possible that beyond the free end the receiving unit is kept closed by pressure contact in such a way that elements can be added particularly easily, but it is still ensured that collectivized elements do not accidentally leave the receiving unit and get lost.

According to a further development, the first end is designed to be at least partially free-standing when the device is in the first open state. This allows the user to add elements over the free standing first end.

According to a development, the second end is not designed to be free-standing when the device is in the first open state. This is very space-saving and particularly safe. The risk of injury is reduced.

According to a further development, the second end is designed to be at least partially free-standing when the device is in the second open state. This allows the user to add elements via the free-standing second end.

According to a further development, the first end is not designed to be free-standing when the device is in the second open state. This is very space-saving and particularly safe. The risk of injury is reduced. The user now has two options and can choose the end through which he would like to open the device. The other end does not pose a risk of injury.

According to a further development, the device enables a direct change of state between the closed and the first open state, as well as a direct change of state between the closed and the second open state, whereby the device does not change the state between the first and the second open state directly, but only indirectly via the closed state State enables. In this way, in particular, inadvertent failure to close is avoided, for example due to an accidental transition from the first open to the second open state. The device is very easy and intuitive to use. For example, the device, which was opened, for example, by a clockwise rotary movement, then closed again by turning counterclockwise.

According to a further development, the second end is essentially straight / flat in the plane of the wire-like material, while the first end is angled at one or more points in relation to the plane of the wire-like material essentially to achieve the arch shape (as defined herein) In particular, the first end can be angled at two points in opposite directions, so that an effective s- or z-like shape is created. This solution is extremely elegant and particularly easy to manufacture. A free-standing end is therefore parallel to the ring and allows new elements to be easily threaded onto the end.

The device of the present invention is used in particular to pick up objects or elements to be collectivized, in particular keys, tools and the like.

In addition, the device according to the invention can be used as a detachable connecting element (ie as a linking link that can be opened and closed) for elements to be connected to one another (for example within a chain). When the device is subjected to a tensile force (e.g. a load), the permanent tension load advantageously enables the two ends of the wire element in the locking unit to be more closely interlocked and interlocked with one another ( 3 ) relative to the recording unit. Thus, even large loads can advantageously be safely coupled to other objects via the device according to the invention. At the same time, simply twisting the ends relative to one another allows the closure unit to be opened and closed quickly, so that objects can be easily and safely inserted into or removed from the device according to the invention.

Bulges ( 8th ) be provided for the elements to be linked (these bulges are not limited to this development, but one or more can also be provided for the other embodiments of this invention). These bulges ensure that the elements to be linked remain in a fixed position under pressure.

Regardless of the embodiment or its use, the central area of the wire element forms the receiving unit ( 2 ), whereby the acquisition unit ( 2 ) is limited to the inside by a circumferential side of the wire element (referred to as the inside of the receiving unit).

According to a preferred embodiment of the present invention, the receiving unit ( 2 ) at least two such bulges ( 8th ) related to the level of the receiving unit ( 2 ) are arranged protruding into this. As a result, between each bulge ( 8th ) and the inside of the receiving unit ( 2 ) a compartment (ie a receiving area) is formed (see e.g. 10 (A) ). Through the area between the two bulges ( 8th ), a resistance is also generated that the elements have to overcome. The size and the (negative) shape of the compartment can be adapted to the (positive) shape of the elements to be collectivized, which prevents the elements to be collectivized from slipping unintentionally or "jumping around" in a disorderly manner.

Alternatively, it can be provided that one or more bulges ( 8th ) are designed in such a way that they relate to the level of the receiving unit ( 2 ) are arranged protruding from this, and each bulge ( 8th ) thereby forms the aforementioned compartment itself (see e.g. 9 (A) and (B)).

It goes without saying that the person skilled in the art can select the thickness as well as the (material) strength of the wire element depending on the required tension load (see 6 (A) compared to 6 (B) ).

The present invention also encompasses a method for producing the device for receiving objects or elements to be collectivized.

1. a) das Bereitstellen eines Drahtelementes mit den vorgenannten Merkmalen durch einen umformenden Prozess eines Drahtes oder durch einen urformenden Prozess, wie hierin definiert; und
2. b) optional das Nachbearbeiten des in Schritt a) bereitgestellten Drahtelementes, wie hierin definiert.

The method for producing the device for picking up objects to be collectivized comprises the following steps:

1. a) the provision of a wire element with the aforementioned features by a forming process of a wire or by a primary forming process, as defined herein; and
2. b) optionally reworking the wire element provided in step a), as defined herein.

In principle, a device according to the invention can be produced using various methods.

A possible reshaping method for producing the device according to the invention is the production by hand in connection with The wire is bent and cut to size without a precisely defined and precisely reproducible geometry. Bending is conceivable, for example, using special pliers that allow wire to be bent in a controlled manner, but without damage.

The advantage of this production method is that the geometry can be selected relatively freely and flexibly. Different geometries can be implemented without major adjustments. Furthermore, there is also a great deal of freedom in the wire material to be used.

Another transforming method for producing the device according to the invention is production with the aid of production devices. Here, the wire is bent and cut to size using production devices specially manufactured or aligned for this purpose. Devices are conceivable which precisely position the wire to be bent and then perform a previously determined and precisely defined bend on the positioned wire.

This manufacturing method has the advantage that the wire element can be bent in a precise and precisely defined manner. This enables an exact reproduction of geometries. In addition, the effort required for bending can be reduced with the aid of the device. For example, leverage can be used. The expected output rate per unit of time is higher here than with the previously mentioned method.

The device according to the invention can advantageously be aligned specifically for the geometry to be generated.

Another transforming method for producing the device according to the invention is production with (computer-aided) machines. In this method, machines are used that have a high degree of flexibility. In principle, they are not specifically designed for the geometry required for the wire element to be produced, but can be used universally. In the case of computer-aided machines, only individual programming usually has to be carried out so that the desired geometry can be implemented. However, depending on the desired geometry, it may also be necessary that the machine is equipped with a suitable tool. Currently available machines of this type are often able to map the complete bending process that is necessary to create the desired geometry. The bending process can take place fully automatically.

The advantage of this production method is that the machines can be used very flexibly. A machine can generate an indefinite number of geometries and, apart from the tool, does not have to be adjusted. In addition, these machines are capable of realizing the desired geometry in a repeatable and very precise manner. They need relatively little time for this, so that the expected output volume per unit of time is comparatively high. In addition, the force required is completely taken over by the machine, which is why fatigue effects, as in the previously mentioned processes, are not to be expected.

In addition, the wire element according to the invention can also be produced using primary forming processes. Solid bodies with a geometrically defined shape are made from shapeless materials. The most suitable methods for manufacturing a wire element according to the invention are the primary shaping from the liquid state and the primary shaping from the plastic state. Both processes combine that the shapeless materials for production are brought into an individually made mold and shaped there. The cast parts produced in this way then at least largely correspond to the desired geometry and may have to be reworked in order to achieve the desired geometry.

The advantage of this manufacturing method is that geometries can be implemented that cannot be implemented in the aforementioned manufacturing methods.

With this manufacturing method, it can be advantageous that post-processing can be dispensed with due to precisely fitting manufacturing of the casting molds, so that manufacturing costs are minimized.

The wire element according to the invention can also be manufactured using additive manufacturing. With this production method, material is applied in layers, which allows three-dimensional objects to be created. The machines used can be used universally and are computer-controlled. They therefore do not have to be adapted to the geometry to be generated, but simply programmed so that the layers can be applied as desired.

The advantage of this manufacturing method is that relatively complex geometries can also be easily implemented. In contrast to the two previously mentioned methods, no individual mold has to be created here, which reduces costs.

A combination of the various manufacturing processes for manufacturing the wire element according to the invention is also possible.

1. a. Bewegen eines Drahtes, vorzugsweise eines sogenannten Unendlichdrahtes innerhalb einer Drahtbiegemaschine bis zu einem Arbeitsbereich der Drahtbiegemaschine (sog. Vorlauf);
2. b. Fixieren des Drahtes und/oder Definitieren des Bewegungsspielraums des Drahtes. Dies erfolgt beispielsweise durch im Raum bewegliche und der Drahtbiegemaschine zugehörige Drahtführungswerkzeuge, welche den Draht fixieren und/oder seinen Bewegungsspielraum definieren;
3. c. Formgeben des Drahtes, wobei der Draht umgeformt wird, sodass die hierin definierte Geometrie der erfindungsgemäßen Vorrichtung ausgebildet wird, wobei diese insbesondere aus der Aufnahmeeinheit und der Verschlusseinheit gebildet wird; Dabei erfolgt das Formgeben des Drahtes durch eine Kombination von Biegen und Bewegen (Vor- oder Rücklauf) des Drahtes zu der gewünschten Geometrie; Dieses Formgeben des Drahtes kann beispielsweise durch ein Zusammenspiel von im Raum beweglichen sowie der Drahtbiegemaschine zugehörigen Drahtführungswerkzeuge erfolgen. Die Drahtführungswerkzeuge definieren hierbei den Bewegungsspielraum des Drahtes und biegen diesen auch;
4. d. Trennen des in Schritt c) ausgebildeten Drahtelementes, wie hierin definiert, von dem restlichen Draht; wobei das erhaltene Drahtelement vorzugsweise gleichzeitig von der Drahtbiegemaschine ausgeworfen wird.

For example, the method for manufacturing the device according to the invention comprises the following steps:

1. a. Moving a wire, preferably a so-called infinite wire, within a wire bending machine up to a working area of the wire bending machine (so-called advance);
2. b. Fixing the wire and / or defining the range of motion of the wire. This is done, for example, by means of wire guide tools that are movable in space and belonging to the wire bending machine, which fix the wire and / or define its range of motion;
3. c. Shaping the wire, the wire being reshaped so that the geometry of the device according to the invention defined herein is formed, this being formed in particular from the receiving unit and the closure unit; The wire is shaped by a combination of bending and moving (forward or reverse) of the wire to the desired geometry; This shaping of the wire can take place, for example, through an interaction of wire guide tools that are movable in space and that are associated with the wire bending machine. The wire guide tools define the range of motion of the wire and also bend it;
4. d. Separating the wire element formed in step c), as defined herein, from the remainder of the wire; wherein the wire element obtained is preferably ejected from the wire bending machine at the same time.

The production can take place fully automatically, semi-automatically or manually.

When using a fully automatic wire bending machine, it has the tools required for the forming process, which enable the wire to move during the manufacturing process. Thus, during the entire forming process, the wire can be moved alternately in both directions by the wire bending machine and also held (i.e. positioning the wire and / or defining the range of motion of the wire).

The working area is defined herein as the area within the wire bending machine in which the wire is mainly formed.

Steps b) and c) preferably take place in an interplay with one another (ie simultaneously, repeating one after the other or repeating according to a defined pattern) in order, in combination, to gradually give the wire element the final shape (ie geometry, as defined herein). When using a wire bending machine, static tools and active tools work together in the work area of the wire bending machine, for example to define bends within the wire. For example, the wire is first bent to a first wire end ( 4th , 4 ' ), it closes the design of the receiving unit ( 2 ) on and finally the design of the second wire end ( 4th ) or. ( 4 ' ).

Post-processing of the wire element may be necessary depending on the intended field of application and the manufacturing process used. It can be the case that the wire element has burrs, sharp edges, unevenness, surface roughness, etc. after production, which are not desired.

For the post-processing of the wire element, basically all cutting processes can be used. Which of these processes can be used depends on the material used and the need for post-processing.

An example of machining with a geometrically undefined cutting edge is vibratory grinding. Here, the workpieces to be processed (i.e. the wire elements produced at the beginning) are placed in a container as bulk goods together with grinding tools and usually an additive in an aqueous solution. An oscillating or rotating movement of the working container creates a relative movement between the workpiece and the grinding body, which causes material to be removed from the workpiece, in particular at its edges. The surface appearance of the workpieces, the roughness, the material removal and the deburring performance can be varied almost as desired by the machines and tools used.

The advantage of this process is that it is very economical. A large number of workpieces to be machined can be machined at once. Furthermore, they can also be cleaned in the container so that they can be removed cleanly. In addition, the acquisition and operating costs of the machines used are relatively low.

Another example of machining with a geometrically undefined cutting edge is grinding the wire elements produced at the beginning with hand-held machines or by hand.

The advantage of this method is that the workpieces to be processed can be treated individually. Post-processing can thus take place in a more targeted manner.

It can be provided that the workpieces are cleaned in a further work step after processing.

Milling is an example of machining with a geometrically defined cutting edge. In this process, material is removed by a milling tool rotating around its own axis at high speed, while either the tool follows the contour to be produced or the workpiece (i.e. the wire element produced at the beginning) is moved accordingly.

The advantage of this process is that a relatively large amount of material can be removed in a short time. The surfaces produced by the milling also have a relatively high quality.

It may be necessary to machine only one workpiece at a time during this process. Furthermore, it can be provided that the workpieces are cleaned in a further work step after machining.

A combination of the various methods for reworking the wire element according to the invention is also possible.

1. a. Bereitstellen von Schleifkörpern in einem Behälter;
2. b. Kontaktieren der in Schritt a) bereitgestellten Schleifkörper mit dem in Anspruch 18 erhaltenen Drahtelement;
3. c. Vermischen der Schleifkörper mit dem Drahtelement durch Oszillieren und/oder Rotieren des Behälters, wodurch die Drahtelemente einen Materialabtrag erfahren;
4. d. Abtrennen der in Schritt c) erhaltenen Drahtelemente von den Schleifkörpern, insbesondere durch Aussieben und/oder Magnete.

The method for post-processing a wire element, in particular wire element obtained by a method defined herein for its production, comprises, for example, the following steps:

1. a. Providing abrasive articles in a container;
2. b. Contacting the abrasive bodies provided in step a) with the wire element obtained in claim 18;
3. c. Mixing the grinding bodies with the wire element by oscillating and / or rotating the container, whereby the wire elements undergo material removal;
4. d. Separating the wire elements obtained in step c) from the grinding bodies, in particular by sieving and / or magnets.

In a fully automatic or semi-automatic method for reworking the wire element, suitable grinding bodies and, if necessary, the additive are selected beforehand, depending on the type and quantity, depending on the initial properties of the wire elements and the desired result after processing.

So-called compounds, for example, come into consideration as additives. The compound is used to absorb and remove the abrasion of the grinding bodies and the removal of the workpieces. Most compounds also contain substances for corrosion protection and degreasing. Pickling work can be done with acidic compounds.

In the case of flat workpieces or sheet metal parts, separating agents are also added as an additive (plastic beads <1 mm) to prevent the workpieces from sticking together (adhesion).

Most compounds can be used for many metals and non-metals, such as For example: Ag, Au, Ni, Cu, Sn, Zn, Fe and its alloys and plastics of all kinds can be used. Such grinding, pickling and polishing compounds and degreasing agents are known to the person skilled in the art or they can be found in the relevant literature.

Provision can be made for an additive to be added to the grinding tools provided before the contacting in step b), the grinding tools and the additive preferably being homogenized (i.e. mixing of grinding tools and additives) before the wire elements are added. For example, the homogenization takes place via an oscillating and / or rotating movement of the working container.

The person skilled in the art is familiar with suitable grinding bodies and additives for this purpose, so that he can select the grinding bodies and additives required for reworking in a targeted manner.

Depending on the desired final state of the wire element, a multi-stage vibratory grinding process may be necessary. Here, the aforementioned method for post-processing is repeated at least one more time, so that the wire elements then experience several vibratory grinding passes with varying process parameters.

For example, machining with coarse grinding wheels is carried out first, followed by machining with finer grinding wheels. The wire elements can also be brought to a high gloss.

After the above-described processing of the wire elements, they have to be separated cost-effectively from the grinding tools and, if necessary, the additive. One possible approach for this is sieving. For this purpose, the entire contents of the working container are passed through a sieve guided, which is designed so that grinding media and additives fall through the sieve so that only the wire elements remain on the sieve.

Character descriptions

The 2 (A) to 2 (C) are schematic representations of a first embodiment of the present invention in the closed state. In this embodiment, the ends of the wire element in the closed state point essentially parallel in a common direction, whereby a loop-shaped topological arrangement of the wire element arises overall.

The terms “essentially (anti-) parallel” emerge for the person skilled in the art from a function-oriented view. Small angles, for example up to 30 degrees, are particularly preferred here. In extreme cases, however, angles of up to 90 degrees can also be used.

The first ending ( 4 ' ) is in an area ( 5 ) preferably arcuate, whereby it is from a rear side of the second end ( 4th ) on the front of the second end ( 4th ) is transferred and the device closes securely.

The 1 (A) to 1 (C) are schematic representations of the first embodiment of the present invention in an open state. The device can be transferred between the open and closed state by simple, intuitive pressing or rotating movements.

The 2 B) is a schematic representation of a first embodiment of the present invention in the closed state in a rear view from behind.

The 1 (B) Fig. 3 is a schematic illustration of the first embodiment of the present invention in an opened state in a rear view from behind.

The 2 (C) shows a schematic representation of the first embodiment of the present invention in the closed state as a profile view from the right.

In this embodiment the second end is ( 4th ) designed in such a way that it runs in a straight line when viewed from the right from the profile view. So there are no further arches or bends here. As a result, the locking mechanism is very easy to manufacture and can be produced inexpensively.

But there are also other shapes such as arches etc. also for the second end ( 4th ) conceivable. For example, shapes are particularly conceivable that have a form-fitting interaction or further interaction of the second end ( 4th ) with the first end ( 4 ' ) allow.

The 1 (C) is a schematic representation of the first embodiment of the present invention in an open state as a profile view from the right.

The 3 shows a schematic representation of a second embodiment of the present invention in the closed state in a front view.

The wire element ( 1 ), which is referred to simply as a wire element in the following, can actually be designed as a wire element in the narrower sense. But it can also be an element made of wire-like material. It can also be a different material which has a certain elasticity. An elastic material strives to return to its original shape under deformation. Due to the elasticity, the device can be closed particularly securely, can be opened securely, and can remain securely in an open state. This makes the receiving device very convenient to use, very safe and no collectivized objects, such as keys, are accidentally lost.

In the embodiment shown, the ends of the wire element in the closed state point essentially anti-parallel in opposite directions, in particular an annular topological arrangement of the entire wire element being produced. As a result, the entire device is closed as a ring, the device is more symmetrical, easier to stow and the risk of injury is lower. An alternative solution by another embodiment is shown in Related to 1 (and subsequent figures).

The first ending ( 4 ' ) is in an area ( 5 ) preferably arcuate, whereby it is from a rear side of the second end ( 4th ) on the front of the second end ( 4th ) is transferred and securely closes the ring.

The 4th shows a profile view of the second embodiment of the present invention in the closed state as a profile view from above. The first ending ( 4 ' ) is in an area ( 5 ) preferably arcuate, whereby it is from a rear side of the second end ( 4th ) on the front of the second end ( 4th ) is transferred and securely closes the ring.

In this embodiment the second end is ( 4th ) designed in such a way that it only continues the course of the ring, but it runs in a straight line when viewed from the profile view from above. So there are no further arches or bends here. As a result, the locking mechanism is very easy to manufacture and can be produced inexpensively.

But there are also other shapes such as arches etc. also for the second end ( 4th ) conceivable. For example, shapes are particularly conceivable that have a form-fitting interaction or further interaction of the second end ( 4th ) with the first end ( 4 ' ) allow.

The 5a Fig. 3 is a schematic representation of the second embodiment of the present invention in the closed state. In this context, reference is made to the one already discussed 4th referenced.

The 6a and 7a show corresponding further views of the closed state.

The 5b , 6b and 7b are schematic representations of the second embodiment of the present invention in a second open state (to the left). The second end ( 4th ) is now free-standing, whereby, for example, further elements to be collectivized such as keys can simply be placed on the second end ( 4th ) can be attached. Due to the elasticity of the material and the frictional contact of the first end ( 4 ' ) with the ring, the ring itself remains closed in that no elements can unintentionally leave the ring, for example through clumsy handling and consecutive falling of keys. With a simple, intuitive twist of the finger, the device can be removed from the closed state of the 2 transfer to the open state (and vice versa).

The 5c , 6c and 7c are schematic representations of the second embodiment of the present invention in a first open state (to the right). The first ending ( 4 ' ) is now free-standing, whereby, for example, further elements to be collectivized such as keys can simply be placed on the second end ( 4th ) can be attached. Due to the elasticity of the material and the frictional contact of the second end ( 4th ) with the ring, the ring itself remains closed in that no elements can unintentionally leave the ring, for example through clumsy handling and consecutive falling of keys. With a simple, intuitive twist of the finger, the device can be removed from the closed state of the 2 transfer to the open state (and vice versa). The direction of rotation for the second open state is in principle the opposite of that for the first open state.

The 9 (A) shows a schematic representation of a third embodiment of the present invention in a closed state in an application context as a link, wherein the locking unit ( 3 ) analogous to that in the 1 and 2 is trained. A left and a right element are connected by using the device according to the invention as a link. For this purpose, “bulges” (8) for the elements to be linked are provided in the receiving unit (these can also be provided for the other embodiments of this invention). These ensure that the elements to be linked remain in a fixed position under pressure. If the chain is subjected to tensile stress, the second end ( 4th ) only more in the preferably arched design ( 5 ) of the first end of the wire element ( 4 ' ) pressed. Similar to the first variant, the linkage can be opened and closed easily and is mechanically very safe and resilient.

The 9 (B) shows a schematic representation of a fourth embodiment of the present invention in a closed state in an application context as a link. The embodiment shown is mechanically even more resilient than the third embodiment according to FIG 9 (A) . The material thickness is increased compared to the third embodiment. The second end ( 4th ), when closed, fits positively into the preferably arched design ( 5 ) of the first end of the wire element ( 4 ' ) a. As a result, the device can be exposed to high forces and force fluctuations without yielding or being damaged. This embodiment is particularly suitable for mechanically demanding application contexts such as, for example, in heavy industry.
