Description

The invention relates to an adjustable ring element. The invention also relates to the use of such an adjustable ring element as an edge part of a springform pan. The invention also relates to a springform pan.

Ring elements are used, for example, in springform pans, where they form the edge of the springform pan. The ring elements are usually adjustable in their circumferential width. As a result, the ring elements can be braced against a base part in the case of a springform pan.

Previous springforms, such as those from the DE 87 04 729 U1 are known, have a clamping lever. The clamping lever is to be pivoted in order to adjust the springform ring in its circumferential width. The tension lever is part of a tension lock which is attached to the springform ring.

One object of the invention is to propose an alternative concept for a ring element of the type mentioned at the beginning and / or for a closure which can be used in a ring element of the type mentioned at the beginning. In particular, the ring element should be suitable to be used as a ring for a springform pan.

The object is achieved with a ring element which has the features of claim 1. To achieve the object, a manufacturing method with the features of claim 17 and an assembly method with the features of claim 18 are also proposed. In addition, a use with the features of claim 19, a springform pan with the features of claim 20 and a closure device with the features of claim 21 are proposed to achieve the object. Advantageous embodiments and / or refinements and / or aspects of the invention emerge from the subclaims, the following description and the figures.

A basic ring element comprises a base body which extends over a circumference, preferably in the form of a ring around a central axis and preferably has a band structure with a width extending in the direction of the central axis.

In the present description, the term “ring-shaped” refers in particular to any type of shape that forms a ring structure. The ring structure can be round, in particular circular or oval. The ring structure can also be angular, in particular polygonal, such as, for example, square. The ring structure can also have any other contour, for example an outer contour of a heart, for example in order to be able to form the springform ring of a heart-shaped springform pan.

In the present description, the term “band structure” is to be understood as meaning, in particular, a structure in the manner of a band. In particular, the term “band structure” is to be understood as meaning a strip-shaped structure which is preferably of flat design. In particular, the band structure has an elongated extension and its width preferably extends transversely thereto. In particular, the longitudinal extension of the band structure extends over the circumference of the base body or forms the circumference of the base body. For example, the band structure is designed to be dimensionally stable and / or resilient.

In particular, it is provided that the ring element is adjustable, in particular designed to be adjustable in its circumferential width. For this purpose, it is provided in particular that the ring element has an adjusting device which enables the circumferential width of the base body to be adjusted.

In particular, it is also provided that the base body has two circumferential ends. For example, the two circumferential ends are formed by the two longitudinal ends of the band structure. One possible embodiment now consists in that an insertion receptacle is arranged at one of the two circumferential ends and an insertion section is arranged at the other circumferential end and the insertion section engages or is introduced into the insertion receptacle via an insertion opening. This approach aims to achieve a closed ring structure through a plug connection. The ring structure can also be opened by the plug connection, for example by bringing the plug-in section out of the plug-in receptacle.

In a further embodiment, it is provided that the adjustment device has an active section assigned to the plug-in receptacle and an active section assigned to the plug-in section. For example, the one active section is arranged on the plug-in receptacle. For example, the other active section is arranged on the insertion section. In this respect, the adjusting device uses the plug-in receptacle and the plug-in section in order to change the circumferential width of the ring element or of the base body.

In particular, it is also provided that the adjusting device has an actuating part which is used, for example, to actuate the adjusting device, that is to say around the circumferential width of the To adjust the ring element or the base body. The actuating part is particularly designed to act against the active sections in order to adjust the plug-in receptacle and the plug-in section relative to each other, in particular to adjust the plug-in section and the plug-in receptacle in their current position relative to each other, and thus to change the circumferential width of the ring element or the base body . The actuating part and the active sections propose an adjusting device which promotes a technically simple implementation.

This is also the aim of the measure that, according to a further embodiment, the actuating part is supported against one of the active sections and is set up to be moved against the other active section in order to adjust the plug-in receptacle and the plug-in section relative to one another. For example, the actuating part is rotatable about an axis of rotation running radially with respect to the central axis of the ring element and is preferably designed to adjust the plug-in receptacle and the plug-in section relative to one another by rotating about the axis of rotation.

In a further embodiment, the plug-in receptacle comprises two side surfaces, in particular exclusively two side surfaces, which are arranged at a distance from one another to form a receiving space for the plug-in section. The receiving space is, for example, an intermediate space in which the insertion section engages or is received via the insertion opening.

In particular, it is provided that one of the two side surfaces of the plug-in receptacle is assigned to a wall section, the wall section being formed by a material section molded onto the base body or being formed on such a material section. This promotes simple and / or inexpensive production of the ring element, since at least a part of the plug-in receptacle can be formed from the section of material that is already present. For example, the base body and the material section are made from a common blank and / or made from one piece. For example, the material section is arranged in the area of one of the two longitudinal ends, in particular formed there on the base body.

The measure aims in the same direction when, according to a further embodiment, the insertion section is also formed by a material section molded onto the base body. For example, the base body and the material section for the one side surface of the plug-in receptacle and the material section for the plug-in section are then made from a common blank and / or made from one piece. For example, the material sections are each arranged in the area of one of the two longitudinal ends, in particular formed there on the base body.

In order to form the one side surface of the plug-in receptacle, it is advisable to undertake a reshaping of the material section due to the molded-on material section. The use of a forming process facilitates the automated production of the ring element, for example in a production line. In particular, achieving short piece times and / or production times is promoted.

For example, bending is used as a forming process. In a pertinent embodiment, one side surface of the plug-in receptacle is formed by bending the material section around a bending line running transversely to the circumferential extension of the base body. As a result, the material section has, for example, a bending edge running transversely to the circumferential extension of the base body. For example, the bending line and / or the bending edge runs in the direction of the central axis of the ring element or the base body.

In one possible embodiment, it is provided that the other side surface of the plug-in receptacle is formed on a wall section of the base body, for example on an outside of the wall section of the base body. As a result, a component of the plug-in receptacle is formed by the base body itself. This favors simple and / or inexpensive manufacture of the ring element. In particular, this favors short piece times and / or production times in the manufacture of the ring element.

If one side surface of the plug-in receptacle is formed by bending the one material section and the other side surface of the plug-in receptacle is formed on a wall section of the base body, bending of the material section is possible in such a way that the material section is folded over in relation to the wall section of the base body to such an extent that the material section and the wall section come to lie in a mutually spaced-apart position with the formation of the above-described receiving space for the insertion section.

In a further embodiment, the plug-in receptacle has a side delimitation in order to prevent a lateral movement of the plug-in section engaging in the plug-in receptacle in direction direction of the central axis of the ring element to limit or avoid. For example, the side delimitation is formed by the edge or the edge of the insertion opening.

A simple and / or inexpensive production of the ring element is favored if, according to a further embodiment, the insertion opening is assigned to the material section on which the one wall section for the insertion receptacle is formed and which is formed on the base body. For example, the insertion opening is formed on this material section, for example formed by a material recess.

A possible arrangement of the insertion opening and the bottom of the insertion receptacle can be implemented in such a way that said material section is molded onto the base body in the area of its one end, in particular is molded onto the base body with one end, and the base body is circumferentially over a length segment overlaps and is connected, in particular fastened, to the base body in a form-fitting and / or force-fitting and / or material fit, in particular in the region of an opposite free end. For example, the free end of the material section forms the bottom of the plug-in receptacle and the plug-in opening, which is formed, for example, by a material recess from the material section, is arranged opposite to this.

In order to accommodate the insertion section, which is preferably plate-shaped when viewed transversely to the longitudinal extension of the band structure and / or at least partially has the contour of the band structure in the direction of its width, the insertion opening is preferably configured accordingly. For example, the insertion opening is designed as an elongated hole, the longitudinal extent of which extends transversely to the longitudinal extent of the belt structure, in particular extends in the longitudinal direction of the bending edge or the bending line.

Another embodiment is that the material section is arranged in the area of the free end, for example via a transverse extension, between a circumferential wall of the base body and a bent lateral edge section, in particular is held in a fixed position with respect to the base body. For example, the free end of the material section thereby forms a stop or a limitation for the insertion section. The plug-in section can therefore be pushed into the plug-in receptacle up to the limit stop or limit formed by the free end.

The bent-over lateral edge section can be a beveled and / or flanged edge section. For example, by bending over the edge section, the free end of the material section is clamped against the peripheral wall of the base body. These measures are also aimed at achieving the shortest possible piece times and / or production times in the manufacture of the ring element. In the present case, this is favored by the fact that bending deformation can be used to fasten the free end, which is used in any case when flanging or folding the edge.

In a further embodiment, the actuating part is rotatably mounted via a rotary bearing on one of the wall sections of the plug-in receptacle, in particular rotatably mounted about the axis of rotation described above. For example, the rotary bearing is formed on the molded material section. This promotes the fact that the actuating part is rotatably held in a predetermined and / or defined position on one wall section.

In particular, it is provided that the one active section, which is assigned to the plug-in receptacle, is formed on the rotary bearing. As a result, the rotary bearing is used to assist in adjusting the circumferential width of the base body. In this respect, this results in advantages in the production of the ring element, for example with regard to the piece time and / or the production time and / or the component costs.

The pivot bearing can be formed by a through opening made in the one wall section or the integrally formed material section, into which the actuating part engages, for example, with a shaft section and is rotatably held therein. The active section formed by the rotary bearing can in this case be formed by a section of the peripheral edge of the through opening.

A further possible embodiment consists in that the other active section, in particular the active section assigned to the plug-in section, is formed by bending a material section, in particular an edge section of the plug-in section, preferably around a bending line running transversely to the circumferential extension of the base body. As a result, this material section has, for example, a bending edge running transversely to the circumferential extension of the base body. The bending in connection with the insertion section and the associated active section is a further optimization for the automated production of the ring gelementes, for example in a production line. In particular, this makes it easier to achieve short piece times and / or production times.

One possible embodiment is that the actuating part comprises a cam and is in particular set up to press the cam with a circumferential section against the other active section, in particular the active section assigned to the plug-in section, during a rotary movement in such a way that the plug-in section is moved further into the plug-in receptacle . A technically simple implementation of the actuating part is promoted by the cam if the adjustment device is to be actuated by a rotary movement.

In a further embodiment, the actuating part further comprises a gripping surface in order to be operated by hand. The grip surface can be formed on a handwheel. For example, the handwheel is arranged outside the plug-in receptacle. For example, the cam is arranged inside the plug-in receptacle, in particular within the receiving space of the plug-in receptacle. For example, the handwheel and the cam are arranged non-rotatably with respect to one another via a shaft section, in particular connected non-rotatably with one another or formed on one another.

In order to be able to mount the actuating part on the base body, one embodiment provides that one of the wall sections of the plug-in receptacle, in particular the wall section formed on the molded material section, has a lateral assembly slot running transversely to the insertion direction of the plug-in section. The actuating part is then pushed into the pivot bearing from the outside.

It is provided in particular that the actuating part is a plastic part, in particular consists of a plastic material or has a plastic material. For example, it is provided that the actuating part consists of a heat-resistant hard plastic or has a heat-resistant hard plastic. For example, the actuating part consists of a thermoplastic material or a thermosetting material or has a thermoplastic material or a thermosetting material. The actuating part 12 can also consist of aluminum or comprise aluminum. For example, the actuating part is a die-cast part.

It is also provided in particular that the base body consists of a metallic material or has a metallic material. For example, the base body is a sheet metal part. For example, the base body and / or the plug-in receptacle and / or the plug-in section are made from one piece.

According to one aspect, a method for producing the ring element described above, in particular its base body, is proposed. In particular, the method comprises the step of providing a blank, in particular a strip-shaped blank. In particular, the method further comprises the step that a material section of the blank is bent about a bending line running transversely to the longitudinal extension of the blank in order to form the one side surface of the plug-in receptacle of the base body. This results in the advantages already described above in connection with bending forming.

According to a further aspect, a method for assembling the adjusting device of the ring element described above is proposed. In particular, in the method, the plug-in section is inserted into the plug-in receptacle via the plug-in opening to such an extent that there is a free space for receiving the actuation part between the active section of the plug-in section and a rotary bearing receptacle for the actuating part. In particular, in the method, the actuating part is then pushed into the pivot bearing receptacle from the outside via the assembly slot, the cam of the actuating part lying between the active section of the plug-in section and the plug-in opening. This promotes simple assembly of the actuating part.

According to a further aspect, use of the ring element described above as an edge part of a springform pan is proposed.

According to a further aspect, a springform pan is provided which can be used, for example, for baking cakes and / or cake bases. The springform pan comprises a base part and an edge part which surrounds and / or delimits the base part and is formed by the ring element described above.

The invention also comprises a closure device, for example for the ring element described above and / or for the springform ring described above. The term “closure device” is to be understood in particular as a device for closing or closing, for example in order to close or close an opening.

In one embodiment, the closure device comprises an insertion receptacle and an insertion section which, for example, engages or can engage in the insertion receptacle via an insertion opening. In particular, the closure device further comprises an active section assigned to the plug-in receptacle and an active section assigned to the plug-in section. For example, the one active section is arranged and / or formed on the plug-in receptacle. For example, the other active section is arranged and / or formed on the insertion section.

In particular, the closure device also comprises an actuating part. In particular, the actuating part is designed to act against the active sections in order to adjust the plug-in receptacle and the plug-in section relative to each other, in particular to adjust the plug-in section and the plug-in receptacle in their current position relative to each other, for example when the plug-in section engages in the plug-in receptacle.

The locking device enables locking or closing in that a plug-in connection is generated by means of the insertion receptacle and the insertion section. In addition, the closure device can have an adjustment function in order to adjust the plug-in receptacle and the plug-in section relative to one another. This adjustment function is brought about by the actuating part and the two active sections.

The plug-in receptacle can be the plug-in receptacle described above in connection with the ring element. The insertion section can be the insertion section described above in connection with the ring element. The active sections can be the active sections described above in connection with the ring element. The actuating part can be the actuating part described above in connection with the ring element.

In the 8th the actuating part 12 is introduced into the rotary bearing receptacle 45 via the assembly slot 35 and can be rotated about the axis of rotation 28 in the position shown in order to adjust the circumferential side of the base body 2. In order to prevent the actuating part 12 from becoming detached from the rotary bearing receptacle 45, the plug-in receptacle 7, ie an elevation 41 is arranged on the wall section 20 of the plug-in receptacle 7. The actuating part 12 preferably has a recess 42, which preferably corresponds to the projection 41 ( 9 ).

The elevation 41 is preferably a centering elevation which can be configured, for example, conical, in particular as a straight circular cone, or pyramid-shaped. The projection 41 is preferably formed by shaping the wall section 20. The tip of the projection 41 is preferably located in the axis of rotation 28. The projection 41 is preferably designed to be axially symmetrical with respect to the axis of rotation 28.

The projection 41 preferably has a height such that the clear width between the tip of the projection 41 or the height end of the projection 41 and the opposite wall 17 of the insertion receptacle 7 or an inner collar of the through opening 38 is smaller than the extent of the cam 30 in FIG Direction between the plug-in section 8 and the one wall section 17 of the plug-in receptacle 7.

In order to be able to use the projection 41 for the actuating part 12, the insertion section has a through opening or recess 43 ( 11th ) through which the projection 41 protrudes. The recess 43 is elongated and extends with its longitudinal extension in the insertion direction E, in particular in the direction of the longitudinal extension of the base body 2 or its band structure, in order to ensure sufficient freedom of movement of the insertion section 8 in the insertion receptacle 7.

9 shows an example of the actuating part 12 with the cam 30, the handwheel 33 and the gripping surface 32 provided thereon. The actuating part 12 is shown in a bottom view so that the recess 42 can be seen. As from the 9 It can also be seen that the cam 30 has, in the area of its circumference outside of the axis of rotation 28, the circumferential section 31, which slides along the insertion section 8 when the actuating part 12 rotates about the axis of rotation 28 against the active section 11 and in this way the insertion section 8 continues is inserted into the plug-in receptacle 7 and thereby the adjustment of the circumferential width of the ring element 1 or of the base body 2 takes place.

10 and 11th use the example of the ring element 1 'to show how the circumferential width is adjusted by means of the adjusting device 9. The free end 44 of the plug-in section 8 is pushed so far into the plug-in receptacle 7 that the active section 11 arranged at the free end 44 faces the circumferential section 31 of the cam 30.

By rotating the actuating part 12 about the axis of rotation 28, the circumferential section 31 is now brought into operative contact against the operative section 11 of the plug-in section 8 and presses with the continuous rotary movement of the actuating part 12 against the active section 11, whereby the plug-in section 8 is inserted further into the plug-in receptacle 7 in the plug-in direction E. will. As a result of this further insertion of the plug-in section 8 into the plug-in receptacle 7, the circumferential ends 5, 6 of the base body 2 are moved towards one another and thus the circumferential width of the base body 2 is reduced.

By rotating the actuating part 12 in the opposite direction, the circumferential section 31 of the cam 30 is moved back again and thereby a movement of the plug-in section 8 counter to the plug-in direction E is permitted. By moving the plug-in section 8 counter to the plug-in direction E, the peripheral ends 5, 6 of the base body 2 are moved away from one another and thus the circumferential width of the base body 2 is increased. The movement of the insertion section 8 counter to the insertion direction E can take place by itself due to a possible spring-elastic property of the band structure of the base body 2. This movement can also be carried out manually as a support.
