Cross connection for a stroller or doll's pram

Description

[0001] A cross connection for a carriage frame of a child's or doll's carriage with the features of the preamble of patent claim 1 is disclosed, wherein the carriage frame is designed to be variable in its width by means of the cross connection or the cross connection can only be arranged on the carriage frame. background

[0002] Conventional strollers or doll strollers are usually fixed in width and unchangeable. These are either single strollers for one child or doll, or twin strollers. The frame of the stroller or doll stroller is designed accordingly and has attachments for either one insert or, in the case of a twin stroller, for two inserts. Converting a single stroller into a twin stroller may be necessary under certain circumstances, for example, due to the arrival of a new member of the family. Conversely, it may also be necessary to convert a twin stroller into a single stroller, e.g. .when a child has outgrown the stroller. Adapting the stroller or doll's stroller is usually not possible. Therefore, the described changed circumstances can currently only be addressed by purchasing a single or twin stroller. However, this represents an unnecessary financial burden and is also not sustainable considering the resources required. State of the art

[0003] WO 2010 / 047596 A2 discloses a buggy for transporting children, comprising a frame with first fastening elements for releasably securing a first load. For this purpose, the first load has a first holding device for accommodating a child. Furthermore, the frame is provided with second fastening elements for releasably securing a second load. The width of the buggy frame is adjustable between a first, relatively small frame width and a second, relatively large frame width. The second fastening elements are configured such that they can be used in both the first frame width and the second frame width for releasably securing the second load next to the first load. A disadvantage here is that the width of the buggy frame can only be changed with great effort.The frame cannot be mechanically adjusted to exactly two widths, as would be necessary for the configuration of single and twin carriages.

[0004] US 2002 / 0070531 A1 discloses a jogging stroller that can be expanded from a single seat unit to a double seat unit. The jogging stroller has a U-shaped handlebar assembly with a gripping area having a parting line therein for opening and spreading the handlebar, a handlebar insert arranged within the parting line of the gripping area to create a wider handlebar assembly for accommodating an additional seat. Furthermore, there is a rear axle assembly with an axle having opposite ends, each end carrying a large pneumatic tire, and the axle having a parting line for opening and spreading the axle. Furthermore, there is an axle insert arranged within the parting line of the axle to create a wider rear axle assembly. Furthermore, there are corresponding means for connecting the handlebar assembly to the rear axle assembly.The jogging stroller also includes a front wheel assembly including a front wheel frame, a housing having a front end sleeve, means for connecting the handlebar assembly to the front wheel assembly, and means for connecting the rear axle assembly to the front wheel assembly. A center bar is provided with a torsoward end connected to the handlebar insert and a distal end connected to the front end sleeve of the housing to provide longitudinal structural support for the jogging stroller when the jogging stroller is in dual-seat mode. Finally, a brace member is provided with a lower end frictionally connected to the axle insert and an upper end frictionally connected to the handlebar insert to provide vertical support for the stroller in dual-seat mode.Another disadvantage here is that the width adjustment is mechanically complex and cannot be easily done with a single movement. Furthermore, there are no predefined widths, so widths can also be set that disadvantageously do not form a single or double stroller.

[0005] WO 2001 / 024759 A1 discloses a walking aid for persons with limited walking ability, comprising a first and a second side part. The two side parts are connected via crossbars attached to the two side parts, wherein the crossbars can be moved parallel to one another, thus enabling adjustment of the distance between the first side part and the second side part, so that the width of the walking aid can be varied. The walking aid additionally has wheels and handlebars. The crossbars are moved relative to one another using an adjustment device formed by a gear with a handle lever, wherein the adjustment device is arranged on at least one rod on the second side part. The gear engages with teeth arranged on the crossbar on the first side part, which is connected to the crossbar with the gear.A disadvantage of this state of the art is that only a mechanism for widening is specified, whereby the technical teaching is not sufficient to describe a stroller or doll's pram that can be varied in width so that it can be used both as a single stroller and as a twin stroller.

[0006] US 8 905 427 B2 describes a convertible single- and multi-seat stroller, comprising at least one chassis. The chassis, in turn, comprises a support unit for supporting at least one person, typically an infant, a wheel assembly coupled to the support unit, an engagement element for connecting the chassis to another such chassis, and a pivot element coupled to the support unit, which enables rotation of the support unit with respect to the chassis. The support unit can be rotatably reoriented to enable transport of the chassis, so that the support unit of the chassis and the other support unit of the other chassis can be aligned in a towing position or, alternatively, in a side-by-side position. Task

[0007] It is therefore an object of the present invention to provide a cross connection for a carriage frame of a child's or doll's pram, which cross connection enables the width of the carriage frame to be changed by changing the length of the cross connection, so that the child's or doll's pram can be adapted according to its use as a single or twin pram, or that the cross connection can be arranged on the carriage frame so that, without widening the carriage frame, the cross connection makes it possible to turn a single pram into a twin pram and vice versa. Solution

[0008] The above object is achieved by the features of the characterising part of patent claim 1.

[0009] The subject matter of the invention described below is applicable to both strollers and doll strollers. For this reason, both terms can be interpreted synonymously. The same applies if only a stroller is mentioned in general terms, rather than a stroller or doll stroller.

[0010] The present invention according to claim 1 describes a cross connection for variable width adjustment for a carriage frame of a child's or doll's pram, or only for arrangement on a carriage frame of a child's or doll's pram, wherein the cross connection is designed to be variable in length, at least comprising a scissor mechanism for changing the length of the cross connection and at least two adapter receptacles for releasably fastening an insert.

[0011] Using the adapter mounts, the insert, which advantageously has adapters itself and into which, for example, a child can be placed and / or sat, can be attached to the cross-connection and thus to the stroller frame. The insert's adapters are brought into active connection with the adapter mounts of the cross-connection. They can, for example, be plugged on and clicked in. A click connection is advantageously realized using locking lugs and corresponding locking recesses on the adapter mounts and, accordingly, complementary on the adapters of the insert to be attached to the cross-connection.

[0012] The scissor mechanism makes it possible to adjust the length of the cross connection. Changing the length of the cross connection can also be accompanied by a simultaneous adjustment of the width of the stroller frame if the cross connection is an integral part of the stroller frame. However, it is conceivable that the cross connection is arranged on the stroller frame in such a way that the cross connection can be adjusted in length, but the stroller frame remains unaffected. The scissor mechanism advantageously dictates the length-changing or width-changing movement of the adjustable cross connection. This allows for easy operation of the cross connection and prevents incorrect operation. Changing the length of the cross connection is intuitive and is clearly dictated by the scissor mechanism.

[0013] However, other mechanical designs can also be used as a replacement for the scissor mechanism, such as an arrangement with at least one building pulley.

[0014] Further advantageous embodiments of the invention are specified in the claims which refer back to claim 1.

[0015] In an advantageous embodiment of the cross connection, it is provided that the cross connection has at least two outer parts and at least one middle part, which are arranged telescopically, wherein the at least one middle part is at least partially received between the at least two outer parts. The at least two outer parts are designed as a hollow profile and the at least one middle part as a solid or hollow profile, wherein the at least one middle part can be received in a form-fitting manner in the at least two outer parts. The at least two outer parts can be moved towards one another in such a way that the at least one middle part is completely received therein. This telescopic movement, in which the at least two outer parts and the at least one middle part are pushed together or apart, causes the length of the cross connection to change.The at least two outer parts and the at least one central part are advantageously made of plastic, composite material, metal, or a metal alloy. The at least two outer parts and the at least one central part can be made of the same material or of different materials.

[0016] It is conceivable that the profiles intended for the cross connection, ie . Hollow profiles and / or solid profiles can be round, oval, or angular, as well as round. These include, for example, cuboid, square, or triangular profile shapes. However, this is not to be construed as a limitation; polygonal profiles with regular or irregular profile shapes can also be used. Profile or profile shape always refers to the cross-sectional shape.

[0017] It is also advantageously conceivable for the cross-connection to have at least two outer parts and at least one central part, which are arranged telescopically, wherein the at least two outer parts are at least partially accommodated by the at least one central part. In this case, the at least two outer parts can be inserted telescopically into the at least one central part. It is also conceivable for at least one spring element to be arranged in the at least one central part, which exerts a symmetrical force on the at least two outer parts, so that they are always inserted or extended into the at least one central part in equal parts.

[0018] In a further advantageous embodiment of the cross-connection, it is provided that the at least two adapter receptacles are arranged on the at least one central part and / or on at least one of the at least two outer parts. In this case, the adapter receptacles are advantageously oriented vertically upwards so that an insert with its adapters can be plugged on from above. In a cross-connection with two adapter receptacles, these are advantageously arranged symmetrically on the at least two outer parts, in each case in the region of the outer free ends of the outer parts. This advantageously makes it possible to accommodate a single insert and arrange it on the cross-connection, wherein the insert can in turn be varied in width by changing the length of the cross-connection.For the arrangement of two inserts next to each other on the cross-connection, four adapter receptacles are advantageously provided, with two adapter receptacles being arranged on the at least two outer parts and two in front of or on the at least one middle part. The two adapter receptacles on the at least one middle part are again arranged centrally there. The other two adapter receptacles are each arranged in the region of the outer free ends of the outer parts. This makes it possible to arrange two inserts next to each other on the cross-connection and thus on a carriage frame for a stroller or doll's pram.

[0019] The adapter receptacles can advantageously be attached to the at least two outer parts or the at least one middle part by means of a snap or click connection, with the at least two outer parts or the at least one middle part being elastically encompassed and held by a clamp. However, it is also conceivable for the adapter receptacles to be firmly connected to the at least two outer parts or the at least one middle part. It is also conceivable for them to be formed as a single piece.

[0020] In a further advantageous embodiment of the cross connection, it is provided that the cross connection is designed to be lockable in at least two positions using the scissor mechanism, the first position being a basic position and the second position being a spread position that is wider than the basic position. In the basic position, the at least two outer parts and the at least one middle part of the cross connection are pushed together. In this position, the cross connection has its smallest longitudinal extent. This in turn means that the stroller frame for a children's or doll's stroller has its smallest width. The scissor mechanism is closed in this position. In this position, advantageously only one insert can be arranged on the cross connection. In the basic position, the stroller frame forms a single stroller due to the cross connection in its smallest longitudinal extent, which is less wide than a twin stroller.

[0021] In the spread position, the cross-connection has its greatest longitudinal extension. The at least two outer sections and the at least one middle section are pushed apart. The trolley frame with the cross-connection thus has its greatest width. The scissor mechanism is maximally open in this position. In this position, two inserts can advantageously be arranged on the cross-connection. The trolley frame thus forms a twin trolley, which is wider than a single trolley.

[0022] By operating the scissor mechanism, you can switch back and forth between the basic position and the spread position. Simply open or close the scissor mechanism accordingly, which in turn changes the length of the cross-connection and thus widens or narrows the frame for a stroller or doll's pram.

[0023] In a further advantageous embodiment of the cross connection, it is provided that the at least two adapter receptacles are designed to be removable. It is therefore conceivable that the adapter receptacles arranged on at least one central part and / or the adapter receptacles arranged on the at least two outer parts are removable. These can therefore be attached to or removed from the cross connection as required. In this case, it is conceivable to fasten the adapter receptacles to the cross connection, for example using ring sleeves, in a detachable manner using a click or snap connection. The adapter receptacles can also be screwed to the cross connection. It is also conceivable that the ring sleeves that hold the adapter receptacles to the cross connection are screwed to one another.

[0024] In a further advantageous embodiment of the cross connection, it is provided that the at least two adapter receptacles are designed to be pivotable and / or displaceable. In this case, the adapter receptacles can be pivoted about the longitudinal axis of the cross connection or displaced along the longitudinal extent. The pivoting is advantageous because it allows the at least two adapter receptacles to be moved into a use position, in which they are oriented vertically upwards, or into a non-use position, in which they are pivoted away to save space, ie . by at least 90° horizontally up to a maximum of 180° vertically downwards.

[0025] In the use position, at least one insert with corresponding adapters can be plugged and detachably fastened onto the adapter receptacles. Moving the at least two adapter receptacles is advantageous if they are to be moved into a space-saving position, for example because the trolley frame is to be folded together with the cross connection so that the adapter receptacles no longer protrude vertically but can be pivoted into the trolley frame. If the cross connection has four adapter receptacles, for example, but only two are to be used, it is further advantageous if the two unused adapter receptacles can be pivoted into a non-use position so that they do not block an insert that is to be arranged on the other two adapter receptacles in the use position.

[0026] In a further advantageous embodiment of the cross connection, it is provided that the at least two adapter receptacles are designed so that they can be locked in at least one pivoting and / or sliding position. This advantageously determines the at least two adapter receptacles to at least one specific position. It is particularly advantageous for the at least two adapter receptacles to be designed so that they can only permanently assume the two positions - use and non-use position. As a result, they cannot be accidentally moved from these positions. This increases the safety of the cross connection and thus of the trolley frame. At the same time, the determination to, for example, only two positions facilitates operability, since the adapter receptacles can only permanently be moved into one use and one non-use position.This is particularly relevant for pivoting the at least two adapter receptacles. With at least one lockable displacement position, it is advantageous that a fixed distance from one another can be set using the at least two adapter receptacles on the cross connection, so that at least one insert with a corresponding fixed width can be received safely and easily by the at least two adapter receptacles. Two different displacement positions are advantageously provided for each adapter receptacle, so that the distance between the at least two adapter receptacles can be changed or adjusted independently of the change in length of the cross connection. It is therefore now possible, on the one hand, to change the width of a trolley frame by changing the length of the cross connection and, at the same time, to change or adjust the distance between the at least two adapter receptacles by moving and locking theto be adjusted so that at least one insert with a certain width can be accommodated by the adapter holders.

[0027] In a further advantageous embodiment of the cross-connection, it is provided that the at least two outer parts each have at least one locking point for locking an adapter receptacle in the at least one pivoting and / or sliding position. In this case, it is conceivable that the locking points are designed as protruding cylindrical pins whose longitudinal axis extends outwards radially to the surface of the cross-connection. Advantageously, recesses with locking lugs or locking projections are provided on the at least two adapter receptacles corresponding to the locking points, which are suitable for positively fastening the at least two adapter receptacles to the locking points and holding them by means of the locking lugs or locking projections.To do this, at least two adapter receptacles are brought up to the locking points and pressed against them with light pressure, so that the locking points overcome the locking lug or projections and engage positively in the recesses. Depending on the location of the recesses on the adapter receptacles, various pivoting and / or sliding positions can be predefined by the positive engagement of the locking points on the cross connection. Depending on the location of the recesses on the adapter receptacles, specific pivoting angles, such as 0°, 90°, and 180°, can be predefined.

[0028] To improve the stability of the engaged adapter receptacles at the locking points, it is advantageous to arrange them in pairs and diametrically opposite each other on the cross connection. This means that the locking points, or the pins that form the locking points, are arranged opposite each other in pairs around the circumference of the cross connection.

[0029] It is also conceivable for multiple locking points to be arranged near the outer ends of the cross-connection. For example, a pair of diametrically opposed outer locking points and another pair of diametrically opposed inner locking points can be provided on the cross-connection. A gap is created between the inner and outer locking points, between which an adapter receptacle can be moved back and forth. Each adapter receptacle, located within a gap, can be selectively locked at both the inner and outer locking points. This allows the adapter receptacles on the cross-connection to be adjusted in their spacing from one another. The spacing can be adjusted to suit the width of the insert to be used.

[0030] In a further advantageous embodiment of the cross-connection, it is provided that the at least one central part has at least one locking point for locking an adapter receptacle in the at least one pivot position. In this case, the at least one locking point is designed analogously to the aforementioned locking points. The same applies to the adapter receptacles with corresponding recesses, which engage with the at least one locking point on the at least one central part and can thus be fastened to the cross-connection. Depending on where the recesses are arranged on the adapter receptacles, certain pivot angles, such as 0°, 90°, and 180°, can be predetermined.

[0031] In a further advantageous embodiment of the cross-connection, provision is made for a spring element to be accommodated in each of the at least two outer parts, which spring element effects a symmetrical application of force to the at least one middle part from both sides in order to center the at least one middle part between the at least two outer parts. When the longitudinal extent of the cross-connection is shortened, the at least two outer parts are moved towards one another. In this process, the at least one middle part is telescopically received or pushed into the at least two outer parts. At the same time, the spring elements are tensioned when the outer parts are pushed together. Due to the symmetrical arrangement to the right and left of the at least one middle part, the spring elements also effect a symmetrical application of force from both sides, so that the at least one middle part is always arranged centrally between the at least two outer parts.In the simplest case, the spring elements are designed as spiral springs, one end of which rests against the at least one central part and the opposite end of which rests against an internal abutment in the outer parts or on the carriage frame on which the cross connection is arranged. Advantageously, the spring elements ensure that the at least one central part is positioned centrally between the at least two outer parts in every position of the cross connection—even during length changes.

[0032] In a further advantageous embodiment of the cross-connection, the scissor mechanism has two levers in the form of a first lever and a second lever. The levers are advantageously designed as flat irons, whereby their flat design takes up as little space as possible. This allows the scissor mechanism to be arranged on the cross-connection in a space-saving manner. It is also conceivable for the scissor mechanism to be made of a metal alloy, plastic, composite material or a combination thereof. Particularly advantageously, the levers of the scissor mechanism also have the shape of flat irons. This means that the levers are advantageously flat. Furthermore, the levers have inherent rigidity so that they are not deformed when operated by hand. As a result, the scissor mechanism is designed to be sufficiently stable and durable for its intended use.

[0033] In a further advantageous embodiment of the cross connection, it is provided that the second lever is articulated with one end to the first lever and with the other end to one of the at least two outer parts and the first lever is articulated with one end to the other of the two outer parts, so that the scissor mechanism can be closed or opened by moving the first lever, which in turn makes it possible to change the length of the cross connection by pushing the at least two outer parts together or apart.

[0034] In its simplest embodiment, the scissor mechanism with its two levers essentially has a Y-shape. The points at which the levers are hinged are advantageously designed as pivotable pivot points. The ends of the first and second levers, each hinged to the outer parts, form the opening and closing scissors of the scissor mechanism. These ends are opened or closed by flipping the first lever, depending on the direction of flipping. The hinged ends to the outer parts push the ends apart or together. Flipping the first lever advantageously facilitates changing the length of the cross connection.On the one hand, this requires little effort because the scissor mechanism applies physical lever laws, and on the other hand, the first lever only provides two types of movement that cause a change in the length of the cross connection, namely a folding in a first direction, which causes the scissor mechanism to open and thus the at least two outer parts of the cross connection to be pushed apart, and a folding in an opposite direction, which causes the scissor mechanism to close and thus the at least two outer parts of the cross connection to be pushed together.

[0035] In a further advantageous embodiment of the cross-connection, it is provided that the scissor mechanism is limited to the at least two positions by at least two stop points on the scissor mechanism and / or on the cross-connection and / or can be locked in the at least two positions. This advantageously limits the movement range of the levers, in particular of the first lever. This can be brought into the two positions by the two stop points, which create the basic position and the spread position of the cross-connection. This makes it possible to operate the cross-connection, ie . Moving the scissor mechanism to the home or spread position is intuitive and easy for the user. By limiting the movement of the scissor mechanism, incorrect operation is virtually impossible. The anchor points lock the cross connection in both the home and spread positions.

[0036] As an attachment point, it is conceivable that, for example, the first and / or the second lever has a projection against which the first lever and / or second lever strikes and cannot be moved beyond. Furthermore, it is conceivable to have an attachment point as a projection on the cross connection, ie . to be arranged on the at least one central part and / or on one of the at least two outer parts, against which one of the levers of the scissor mechanism strikes in the open and / or closed position and thereby limits the movement of the scissor mechanism. A concrete example of a pivot point can be the pivot point between the first lever and the outer part, against which the second lever strikes in the closed position of the scissor mechanism and cannot be moved beyond it. As a result, the closed position of the scissor mechanism and thus the basic position of the cross connection are fixedly predetermined by the pivot point.

[0037] In addition, it is also conceivable to provide locking devices in the anchor points that fix the levers of the scissor mechanism in the open and / or closed position and thus ensure additional mechanical stability of the cross connection.

[0038] Further advantages, features and design options emerge from the following description of figures of non-limiting embodiments. Brief description of the drawings

[0040] Elements provided with the same reference numerals in the drawings essentially correspond to one another unless otherwise stated. Furthermore, components that are not essential to understanding the technical teaching disclosed herein are omitted. Reference numerals will not be repeated for all elements already introduced and illustrated, provided that the elements themselves and their function have already been described or are known to a person skilled in the art. Detailed description of implementation examples

[0041] Fig. 1shows a perspective view of the cross connection 2 in a spread position, in which it has its maximum longitudinal extent. In the embodiment shown, the cross connection 2 has a central part 8 and two outer parts 7, wherein the central part 8 is arranged between the two outer parts 7 and is partially telescopically received by them. This allows the cross connection 2 to be pushed together and apart, with the central part 8 and the outer parts 7 being pushed into and apart from one another. In the spread position shown, the cross connection 2 has its greatest longitudinal extent.

[0042] Below the cross-connection 2 there is an open scissor mechanism 3 consisting of a first lever 4 and a second lever 5. One end of the second lever 5 is hinged to the end of an outer part 7 facing the central part 8. The opposite end of the second lever 5 is arranged in the region of the middle of the first lever 4. One end of the first lever 4 is hinged to the end of the other outer part 7 facing the central part 8. The opposite end of the first lever 4 is free-standing. It can be grasped by a user and moved or folded around the one outer part 7 according to the hinge of the first lever 4. The scissor mechanism 3 can be closed or, conversely, opened, which would push the cross-connection 2 together or apart.In the embodiment shown, the scissor mechanism 3 is open, so that the two ends of the levers, which are hinged to the outer parts 7, point away from each other and are at their greatest distance from each other. The free end of the first lever 4 points toward the hinge point between the outer part 7 and the second lever 5. .

[0043] The cross connection 2 further comprises four adapter receptacles 6, two of which are arranged centrally on the middle part 8, and one of which is arranged in the area of the outer ends of each of the two outer parts 7. All four adapter receptacles 6 are oriented vertically upwards. They enclose the outer parts 7 and the middle part 8 in a ring-shaped manner and are simultaneously designed to be movable and pivotable on them.

[0044] Furthermore, four locking points 9 in the form of radially outwardly projecting pins are arranged on each of the two outer parts 7. They are arranged in pairs diametrically opposite each other. In the embodiment shown, two pairs of locking points 9 are arranged on each of the outer parts 7, with one pair on each outer part 7 being concealed by the adapter receptacle 6 arranged there.

[0045] The center section 8 also has locking points 9. Two pairs of locking points 9 are arranged centrally on the center section 8. However, in the embodiment shown, they are not visible because they are concealed by the two centrally arranged adapter receptacles 6.

[0046] The adapter receptacles 6 can be attached to the locking points 9 via recesses. In the area of the outwardly directed ends of the outer parts 7, the respective adapter receptacles 6 can be moved between the locking points 6 located there. In the illustrated embodiment, the two outer adapter receptacles 6 are attached to the outermost locking points 9 of the outer parts 7. They simultaneously conceal the aforementioned outermost locking points 9.

[0047] In the configuration shown, the adapter receptacles 6 are suitable for accommodating two inserts and arranging them side by side on the cross-connector 2. The cross-connector 2, as part of a carriage frame for a stroller or doll's pram, forms the stroller as a twin stroller in the spread position.

[0048] Fig. 2 shows a perspective view of the cross connection 2 in a basic position. The cross connection 2 shown here corresponds to the cross connection 2 from Fig. 1in the basic position opposite to the spread position, in which it has its smallest longitudinal extension. The two outer parts 7 are pushed completely together so that the middle part 8 is completely taken up by the outer parts 7 and is therefore no longer visible. The two middle adapter receptacles 9 are pivoted by 90° and are now aligned horizontally and point away from the viewer. They thus expose the middle area above the cross connection 2. The two adapter receptacles 6 on the outer parts 7 continue to be aligned vertically upwards and are simultaneously moved from the outer locking points 9 to the locking points 9 arranged further towards the center of the cross connection and are fastened to these. Accordingly, these locking points 9 are concealed by the adapter receptacles 6. The locking points 9 arranged towards the outer end of the respective outer parts 7 can now be seen.

[0049] The scissor mechanism 3 is closed in the basic position of the cross connection 2. Here, both the first lever 4 and the second lever 5 point in the Fig. 1 The ends of the levers, which are hinged to the outer parts 7, are at their closest distance from one another, thereby establishing the home position of the cross-connection 2. At the same time, the second lever 5 rests or strikes the hinge point between the outer part 7 and the first lever 4. This limits the movement of the second lever 5 and, consequently, of the entire scissor mechanism 3. The scissor mechanism 3 cannot be moved beyond the closed position.

[0050] Fig. 3 shows a schematic view from below of the scissor mechanism 3 of the cross connection 2 with first lever 4 and second lever 5, which is already shown in Fig. 1 and in Fig. 2The scissor mechanism 3 shown is in the closed position.

[0051] The special feature of the scissor mechanism 3 lies in the design of the second lever 5. In the closed position of the scissor mechanism 3, this lever rests on the first lever 4, more precisely on the articulation point between the first lever 4 and the outer part 7 (not shown here). For this purpose, the second lever 5 is V-shaped. The inner notch of the V-shape rests on the aforementioned articulation point of the first lever 4, so that the direction of movement of the second lever 5 and thus of the entire scissor mechanism 3 is limited. All articulation points of the two levers are aligned on an imaginary straight line. This gives the scissor mechanism 3 stability. The two ends of the levers, which are each hinged to the outer parts 7, cannot be moved by force applied to these ends when the articulation points are aligned. The scissor mechanism 3 remains stable in this closed position.The same applies to the open position, in which the pivot points of the scissor mechanism 3 are also aligned on an imaginary straight line. This arrangement simultaneously locks the cross connection 2 (also not shown here) both in the home position, in which the scissor mechanism 3 is closed, and in the spread position, in which the scissor mechanism 3 is open.

[0052] Instead of a V-shape, the second lever can also be curved, provided that the articulation points in the shown closed position of the scissor mechanism 3 are aligned on an imaginary straight line and the second lever 5 rests with its inner side of the curved shape on the articulation point between the first lever 4 and the outer part 7.

[0053] To move the scissor mechanism 3 from the closed position to an open position, which simultaneously causes the spread position of the cross connection, the free end of the first lever 4 must be moved or folded around its pivot point at the opposite end by 180° in the direction of the arrow shown.

[0054] Fig. 4a shows a perspective view of the scissor mechanism 3 in the basic position without outer parts 7 and middle part 8. At the ends of the first lever 4 and the second lever 5 there are two ring-shaped connecting parts for coupling to the two outer parts 7 (see Fig. 1 and 2, not shown here). The two levers 4, 5 are pivotally attached or hinged to the annular connecting parts. The second lever 5 has a slight bend; at the same time, the second lever 5 abuts the pivot point between the first lever 4 and the annular connecting part at the bend point. The pivot points of the two levers 4, 5 are aligned with each other in this position.

[0055] Fig. 4b shows a perspective view of the scissor mechanism 3 in a position between the basic position and the spread position without the outer parts 7 and the middle part 8. Fig. 4b corresponds to the Fig. 4awith half-open scissor mechanism 3. The first lever 4 is pivoted approximately 120° around the articulation point with the annular connecting piece at the outer end of the lever. The simultaneous articulation of the first lever 4 to the second lever 5 causes the outer ends of the levers 4, 5, and thus also the two annular connecting pieces hinged to them, to move away from each other. The distance between the ends of the levers 4, 5 and thus also the annular connecting pieces is increased.

[0056] Fig. 4c shows a perspective view of the scissor mechanism 3 in the spread position without outer parts 7 and middle part 8. The scissor mechanism 3 is shown, which can also be used in different positions in the Fig. 4a and 4bIn this position, the ends of the first lever 4 and the second lever 5, as well as the annular connecting parts hinged thereto, are at their greatest distance from each other. At the same time, the first lever 4 is rotated by 180° compared to the position in Fig. 4a pivoted. In this position, the pivot points on the two levers 4, 5 are again aligned with each other.

[0057] In the Fig. 5a and Fig. 5b a perspective view of the scissor mechanism 3 without outer parts 7 and middle part 8 with extended first lever 4 and extended second lever 5 is shown. Fig. 5a shows the scissor mechanism 3 in the basic position and Fig. 5bthe scissor mechanism 3 in the spread position. In contrast to the scissor mechanism 3 shown in the previous figures, the first lever 4 and second lever 5 are longer here. As a result, the maximum width in the spread position is larger, corresponding to the longer levers 4, 5. This makes it possible to effect a greater change in the length of the cross-connection 2 (not shown here) by opening and closing the scissor mechanism 3. List of reference symbols
