Description

The invention relates to a swing arrangement according to the preamble of claim 1.

Swinging is not just a fun game or relaxing rhythmic movement, but serves, especially in the development of children, the development of balance and spatial-position orientation. For this reason, swings of the most varied types, especially in the children's play area, have been known for a long time.

For example, reveals DE 20 2004 005 120 U1 a swing seat which is arranged on the transverse beam of a frame via two suspension means. When swinging, the swing seat moves on a circular path around the respective axis of rotation, which runs between the suspension points on the crossbeam.

In the classic swing, the seat surface of the swing seat is generally arranged tangentially to the circular path.

The U.S. 5,665,002 A discloses a cage for two people suspended between two towers on elastic ropes. The ropes are tensioned while the cage remains anchored to the ground. If the anchorage is released, the cage is pulled up forcefully and then swings back and forth. A similar bottom-up bungee is revealed US 6,319,140 B1 . Here a cage ball is suspended from ropes, the ropes being arranged at the other end on a spring system that pulls on the ropes and so the cage ball first shoots up and then vibrates. With the systems, the oscillating movement only goes in the vertical direction.

WO 2017 197 458 A1 discloses a swing system in which the swing is classically arranged with a pivot bearing on a transverse beam. What is special about it, however, is that a swivel joint is arranged between the swivel bearing and the seat for the rocking person, the axis of rotation of which is perpendicular to that of the swivel bearing. In addition to the classic rocking movement, the person can also turn around their own axis.

The swing pleasure can be further increased if the movement path of the swing seat deviates from the circular path. So revealed DE 20 2018 005 162 U1 a suspension in which the swing seat is articulated by means of the suspension means to a suspension device which is also suspended in a pendulum manner. The towing device is actively driven, which on the one hand stimulates or decelerates the rocking movement and on the other causes slight deviations from the circular path. The deviation from the movement on the circular path in DE 299 04 798 U1 influenced. There a swing with a forced movement of the suspension is described. The swing's hitch is non-rotatably connected to a pendulum wheel. The pivot axis of the swing, which is identical to the axis of rotation of the pendulum wheel, is arranged on a swing frame, the lower end of the swing frame being arranged to be rotatable. The construct is held by means of control ropes that are placed around the pendulum wheel, tensioned horizontally and arranged on control rope posts. If the swing is set in motion, the pendulum wheel, which takes part in the rotation of the swing, rolls along the control cables and thereby tilts the swing frame. Depending on how the control cables are routed, the oscillation amplitude can be lengthened or shortened.

DE 299 19 980 U1 discloses a swing in which the frame can also move about an axis parallel to the swing axis. The swing frame is stretched elastically so that it can follow the movement of the swing within certain limits and thus increase the deflection of the swing. DE 10 2004 050 537 A1 discloses an alternative to this. In the resting state, the swing frame is a symmetrical trapezoid, in which the rods are rotatably connected to each other at all corners or anchored in the ground. The suspension means is arranged relatively rigidly on the upper cross strut. When swinging, the upper cross strut is also rotated so that the swing frame must move in the direction of the swing deflection and thus extend the swing path.

The known swings have the disadvantage that the swing frames are exposed to high loads, which leads to increased wear, which has a negative impact on safety.

The object of the invention is now to offer a swing arrangement which gives the user a great deal of swinging pleasure and at the same time offers a high level of operational reliability.

The object is achieved by a swing arrangement having the features of claim 1. Preferred embodiments are claimed in the subclaims.

The subject of the invention is a swing arrangement with a, in particular fixed, support device on which a swing seat is suspended with at least one suspension means that can be loaded at least in tension, the suspension means being coupled to the support device, in particular passively, via at least one lever or handlebar. In contrast to a conventional swing, the suspension means is not arranged directly on the fixed support structure, but on a lever or handlebar, which in turn is coupled to the support device. Passive coupling means that the deflection does not take place via a motor or similar drive, but rather by deflecting the swing, i. H. the swing seat out of equilibrium. Fixed means that at least parts of the support device, in particular the support posts anchored in the ground, cannot be changed in position or location during rocking or as a result of the swing seat being deflected. According to the invention, the at least one lever or link is coupled to the support device via a pivot bearing at one end or via a suspension section located between its ends. In order to articulate the lever or the link in a stable manner on the support device, the use of pivot bearings has proven to be advantageous, the at least one lever or link being designed so that the pendulum length of the swing suspension during the rocking movement, especially during the deflection from the rest position is extended.

Two suspension means are preferably provided in the swing arrangement. When using two suspension devices, the connecting line between the suspension points defines a main axis of rotation of the swing, so that it is preferably performed in one plane. It is advantageous if at least one suspension means comprises a rod, a chain or a rope. The above-mentioned suspension means can withstand tensile loads and lead to a stable suspension. Chains and ropes are still so elastic that the risk of injury from a freely swinging suspension means is reduced compared to a rigid embodiment.

It is particularly advantageous that the pivot bearing is fixedly coupled to the support device. Such an arrangement avoids sliding elements and thus additional maintenance costs for the operation.

It has proven to be particularly advantageous if the lever or link is connected to the support device via a joint. This means that the movements of the lever or handlebar are better guided.

In a particularly preferred embodiment, the support device comprises two support posts connected to one another via a cross member, the at least one lever or link being articulated on the cross member, in particular about a pivot axis that is not parallel to the longitudinal direction of the cross member. The use of a crossbeam increases the stability and allows the lever or handlebar to be arranged in such a way that the swing seat located underneath is not disturbed in its movement by the support posts, even if there are deviations from the target oscillation. The lever or handlebar allows it to swing when the swing moves. Particularly when the pivot axis is not aligned parallel to the direction of longitudinal extent (Y) of the cross member, the oscillation causes the Lever or handlebar at the lower point of the swing movement, does not point directly and collinearly downwards to the suspension means, but also to the side, which leads to a shortening of the swing length. The further the swing is deflected, the more collinear is the lever or link with the extension of the suspension means, which increases the length of the swing's pendulum.

In a further particularly preferred embodiment, the support device comprises two erecting posts, and two levers or links are provided, one lever or link being attached to each of the erecting posts via a connecting means, in particular designed as a rope or chain, one end of which is connected to the respective mounting post, in particular in the area of an upper end portion thereof, and the other end of which is connected to a suspension portion located between the two ends of the respective lever or link. The lever or handlebar has a horizontally arranged distance between its suspension and the articulation of the suspension means. In this way, the suspension section can follow the swing of the swing and thus extend the swing's pendulum length when it deflects.

It has proven to be particularly advantageous that one end of the lever or handlebar is connected to a suspension means connected to the swing seat and the other end to a tensioning means that is to be fixed on the floor. The lever or handlebars are pulled into the starting position by the clamping device. This means that the levers or links are aligned in such a way that the suspension sections point towards the center of the swing arrangement and, when the swing is deflected in the deflection direction, rotate with it, in order to avoid the tension can be pulled back into the starting position when the deflection of the swing decreases again.

In another preferred embodiment, the pivot bearing is coupled to the support device so as to be displaceable relative to the latter. If the lever or handlebar is displaceably coupled to the support device, the stability of the connection is reduced somewhat, but greater mobility is achieved in a relatively small space. The pivot bearing is particularly preferably coupled displaceably along a guide provided on the support device. With the guidance, stability can be regained, as the possibilities of movement are more restricted.

It is very particularly preferred that the support device comprises two support posts and the lever or handlebar as a bracket with a first leg displaceably guided on one support post and a second leg displaceably guided on the other support post as well as a leg connecting the legs, in particular angled with respect to the legs , Connecting portion is formed, wherein the at least one suspension means is suspended from the connecting portion. Here the lever or handlebar takes on the function of the cross member to which the suspension means link the swing seat. The lever or handlebar is articulated displaceably on both support devices and thus also ensures that the swing arrangement is stabilized.

In a further very particularly preferred embodiment, one leg is guided displaceably with a first pivot bearing in one support post and the other leg with a second pivot bearing in the other The support post is displaceably guided, the at least one of the legs, in particular both legs, being coupled to the associated support post via a coupling device, in particular a rope or a chain, with a section, in particular one end, of the coupling device with the respective leg at a distance from the pivot bearing and another section, preferably the other end, of the coupling device is connected to the respective mounting post, in particular in the vertical direction above the pivot bearing. When rocking, that part of the lever or handlebar on which the suspension means are arranged is also deflected in the direction of swing movement by the deflected swing seat. The coupling device guides the lever or handlebar, whereby the pull through the swing seat causes the leg of the lever or handlebar guided on the support device to be raised so that the suspension point of the suspension means does not form a semicircle, but rather follows the movement of the swing seat almost horizontally and thus leads to a further deflection of the swing seat. When rocking back, the lever or the handlebar is positioned vertically again in order to also follow the other direction of rocking during the further rocking movement.

In a further preferred embodiment, the support device comprises two support posts and a lever or link each, which is pivotably coupled at one end to a first pivot bearing and the other end to a suspension means, the first pivot bearing being slidably guided on a guide, with at least one of the levers or links between the two ends of which a coupling link is articulated, which is also pivotably connected to a second pivot bearing, wherein the second pivot bearing is displaceably guided on the guide or on a further guide. The two levers or links are not coupled to one another and can in principle move independently of one another, in particular the suspension points of the suspension means can move towards or away from one another. Especially when the swing seat is deflected to the maximum, the two suspension points of the suspension means move apart, which leads to a slight shortening of the effective swing length and makes the swinging movement appear steeper for the swinging person.

In a particularly preferred embodiment, the guide comprises a guide rod, wherein the first and the second pivot bearing comprise sliding bearings that are mounted displaceably on the guide rod. The use of slide bearings reduces the friction that arises when swinging and thereby slows down the swing, which generally increases the enjoyment of swinging.

The invention is explained in more detail below with reference to figures.

In Figure 1 an embodiment of a swing arrangement 1 is shown in the rest position. The support device 20, 21, 22, 29 consists of two support posts 20, 21, which are arranged on the left and right of the swing suspension 10, 11, 12. At the top, the support posts 20, 21 are connected to one another via a cross member 22; at the bottom, the support posts 20, 21 are firmly anchored in the ground via a floor anchor 29, which in the embodiment shown is a base plate. In the case of a classic swing, as is known from the prior art, the suspension means 11, 12 of the swing seat 10 would be hinged directly to the cross member 22. In a swing arrangement 1 according to the invention, the suspension means 11, 12 are each articulated to a link 23, 24, the link 23, 24 in turn on the cross member 22 via a connecting element 25, 26 (in this embodiment it is a pivot bearing) are hinged. The pivot axes A1, A2 of the links 23, 24 are not arranged parallel to the longitudinal direction Y of the cross member 22, but are inclined symmetrically with respect to the longitudinal direction Y, whereby the links 23, 24 with the ends in the rest position of the swing suspension 10, 11, 12 , on which the suspension means 11, 12 are hinged, point outwards. This shortens the effective pendulum length of the swing arrangement 1, the distance between the swing seat 10 and the pivot bearings 25, 26 compared to an arrangement in which the pivot bearings 25, 26 are aligned parallel to the longitudinal direction Y.

If the swing suspension 10, 11, 12 is caused to vibrate, as shown in FIG Figure 2 is shown, the handlebars 23, 24 are pulled by the swing suspension 10, 11, 12. The oscillating movement of the links 23, 24 is guided by the pivot bearings 25, 26, as a result of which the ends of the links 23, 24, to which the suspension means 11, 12 are hinged, move towards one another, the higher the deflection by the swing suspension 10, 11 , 12 is. This increases the effective pendulum length compared to the rest position and the rocking movement becomes more expansive compared to a pure pendulum movement. In this way, a rocking feeling is conveyed in which the pendulum length of the swing is greater than the overall height of the swing arrangement 1 allows.

At the in Figure 3 As shown in the embodiment of a swing arrangement 1 ′ according to the invention, the support frame comprises two support posts 20, 21 which are slightly inclined towards one another and are fixed in the floor by floor anchors 2. The free upper end section 6 of the support posts 20, 21 has a space between the support posts 20, 21 Reaching extension on which a connecting element 25, 26, here in the form of a chain, a rope or a movably arranged rod, is arranged. A lever or link 23, 24 is arranged on these connecting elements 25, 26 on a suspension section 23a, 24a. At one end of the elongated links 23, 24, which are arranged approximately horizontally, a tensioning means 27, 28 is arranged, which is fixed in the ground with a floor anchor 3 in each case. At the other end of the links 23, 24, the suspension means 11, 12 of the swing seat 10 are articulated.

Figure 4 shows a deflection of a swing suspension 10, 11, 12. The swing suspension 10, 11, 12 pulls on the links 23, 24 in such a way that the ends to which the suspension means 11, 12 are hinged are pulled along. The links 23, 24 stretched by the connecting elements 25, 26 and the tensioning means 27, 28 are rotated so that the ends to which the swing suspension 10, 11, 12 is articulated are moved along in the deflection direction. The pendulum length of the swing suspension 10, 11, 12 is thus lengthened in the event of a deflection. The tension built up by the tensioning means 27, 28 and the connecting elements 25, 26 on the levers or links 23, 24 during rotation causes the levers or links 23, 24 to move back into the rest position as soon as the pulling force of the swing suspension 10, 11, 12 decreases, so that the levers or links 23, 24 always move with the swing suspension 10, 11, 12 in such a way that the pendulum length is increased when deflected, which leads to the feeling of sitting on a larger swing than the overall height of the swing arrangement 1 allows it.

Another embodiment shows Figure 5 . The support posts 20, 21 of the support device are arranged on the left and right of the swing suspension 10, 11, 12. The support posts are arranged vertically or at least largely vertically and firmly anchored in the ground by means of ground anchors 29. A vertical slot, which is intended as guides 20a, 21a, is embedded in each of the support posts. The link 23 belonging to the swing arrangement 1 ″ is made in one piece or is at least composed of parts that are firmly connected to one another. The connecting elements 25, 26, which are arranged horizontally and are arranged vertically movable in the guides 20, 21a, are respectively a suspension section 23a, 23b, which in the rest position is oriented vertically, or at least almost vertically, upwards. At the upper end of the suspension sections 23a, 23b, a connection section 23c is arranged horizontally, which firmly connects the two suspension sections 23a, 23b. Symmetrical the suspension means 11, 12 are arranged around the middle on the connecting section 23c. The handlebar 23 is held by a coupling device 30, 31 arranged on each side on the hanging section 23a, 23b. which are preferably designed as pivot bearings, spaced apart on the suspension sections 23a, 23b arranged. The respective other end of the coupling device 30, 31 is connected to the respective mounting post 20, 21 in the vertical direction Z above the pivot bearing 25, 26. The coupling device can be designed as a rope, chain, rod or tube.

If the swing suspension 10, 11, 12 is deflected, it pulls on the suspension of the suspension means 11, 12 and pulls the upper end of the handlebar 23, that is to say the connecting section 23c, with it. The link 23 hangs on the coupling devices 30, 31, so that the deflection pulls the connecting elements 25, 26 in the guide 20a, 21a upwards, so that the connecting section 23c does not move on an arc, but almost horizontally in the direction of the Rocking motion is moved and thus leads to an apparent pendulum lengthening of the swing.

With such an arrangement, it is advantageous if the connecting elements 25, 26 are retracted back into the rest position to support the movement so that the link 23 is positioned vertically again when the deflection of the swing suspension 10, 11, 12 decreases. This retraction can take place on the one hand in that the deflection of the connecting elements from the rest position also takes place against a spring force which acts on the connecting elements 25, 26. It is also conceivable that an additional weight acts on the connecting elements 25, 26 and tries to pull them into a lower position. Any other resetting options are also conceivable. It is important here to carry out the resetting largely synchronously with the oscillation in order to prevent the rocking behavior of the rocking arrangement 1 from being disturbed by a delayed resetting of the link 23.

The Figure 7 shows a further embodiment of a swing arrangement 1 '''according to the invention. The support device is formed by two support posts 20, 21, at the upper end of which an end section 6 pointing towards the center of the swing arrangement is arranged. At the end sections 6 is in each case by means of a clamping device 5 a guide 20a, 21a is arranged, which is firmly anchored at its lower end by means of a further clamping device 4 in the ground. In the upper section of the guide 20a, 21a, a pivot bearing 32.3, 33.3 is fixedly arranged, on which a coupling link 32, 33 is arranged via a joint 32.2, 33.2. Another pivot bearing 23.3, 24.3 that is movable along the guide is also arranged on the guide 20a, 21a. An elongated link 23, 24 is arranged on this pivot bearing by means of a joint 23.2, 24.2. At a distance from the joint 23.2, 24.2, the coupling link 32, 33 is arranged on the link 23, 24 via a further joint 32.1, 33.1. The suspension means 11, 12 of the swing seat 10 are arranged at the free end 23.1, 24.1 of the link 23, 24.

When the swing suspension 10, 11, 12 is deflected from the rest position, the swing suspension 10, 11, 12 pulls at the end 23.1, 24.1 of the links 23, 24 and pulls them in the deflection direction. The links 23, 24 can follow this train by rotating accordingly in the guides 20a, 21a. At the same time, the pivot bearings 23.3, 24.3 slide upwards on the guides 20a, 21a and increase the deflection of the ends 23.1, 24.1 in the deflection direction. When swinging back, the ensemble of link 23, 24 and coupling link 32, 33 rotates about the guide back into the basic position, in order to follow the swing suspension 10, 11, 12 in the opposite direction when swinging further. As in the previous exemplary embodiment, the sliding movement of the links 23, 24 on the guides 20a, 21a should be supported by restoring forces which bring the links back into the rest position. This is intended to delay the reset relative to the oscillation of the swing suspension 10, 11, 12 must be avoided in order not to disturb the swing oscillation.

Here, too, when the swing suspension 10, 11, 12 is deflected, the extension of the pendulum length produces a greater swinging effect than the overall height of the carrying device 20, 20a, 21, 21a would allow.

The fixed carrying devices of the swing arrangement 1, 1 ', 1 ", 1'" 'achieve a high level of stability in the swing To extend the pendulum length of the swing suspension 10, 11, 12, a swing effect is generated which can be assigned to a normal swing that is significantly larger than the height of the support device of the swing arrangement 1, 1 ', 1 ", 1"' allows .
