TRAMPOLINE

Description

[0001] The invention relates to a trampoline, in particular for use as a play device, preferably on a playground, a jumping mat for a trampoline, and a slat, in particular for a jumping mat.

[0002] Trampolines in various designs are regularly used as playground equipment in playgrounds. Trampolines are often particularly appreciated as playground equipment because they help people of all ages, especially children, develop their sense of balance and body coordination. Trampoline jumping also engages the entire body and requires a high level of concentration.

[0003] Trampolines typically have a jumping mat suspended from a steel frame, for example, by tension springs. Trampolines are usually installed in a fixed location on playgrounds. The steel frame with the jumping mat is mounted above a receiving space in the ground at ground level. The jumping mat can be formed, for example, from elongated plastic slats. Such slats often have two openings through which ropes, such as wire ropes, are passed. The slats of a jumping mat are thus threaded onto the ropes, so that the jumping mat is characterized by a pattern of staggered slats. The ropes therefore run perpendicular to the elongated bodies of the slats. Document DE2701446A1 discloses a trampoline according to the prior art.

[0004] The slats are usually rigid, so the jumping mat itself is only movable at those points where the slats are connected to each other at the grommets. Typically, loops are formed at the ends of such ropes, from which the ropes, and thus the jumping mat itself, are suspended on tension springs. The tension springs hold the jumping mat in an articulated position and are connected to the steel frame. The spring effect of the jumping mat, in such designs, results largely from the elastic properties of the tension springs. It is desirable for a trampoline used in a playground to have the best possible trampoline effect and at the same time be robust, low-maintenance, and safe. In particular, it is desirable for a trampoline installed in a playground to stimulate children's urge to move.In order to attract people's interest to a trampoline, for example, motifs can be incorporated into the jumping mat or a trampoline arrangement can be put together from several trampoline modules.

[0005] It is an object of the invention to provide an alternative trampoline, an alternative jumping mat for a trampoline and an alternative slat for a jumping mat.

[0006] According to the invention, this object is achieved by a trampoline according to claim 1, which comprises a jumping mat formed by movably interconnected slats that form a jumping surface of the jumping mat. The slats of the jumping mat each have a slat body with at least two fastening openings and are movably connected to further slats of the jumping mat at the fastening openings. The slats have a tread surface on one step side. The tread surfaces of the movably interconnected slats form the jumping surface. At least one of the slats of the jumping mat has at least one receiving space in which at least one light element is arranged. The at least one light element comprises at least one generator for converting kinetic energy into electrical energy and at least one light source electrically connected to the generator.The generator is arranged and designed such that, in the event of a deflection of the jumping mat, it transfers electrical energy to the lamp, causing the lamp to emit light. The lamp is arranged such that its glow is visible from outside the slat.

[0007] The light element is thus arranged in the receiving space and the slat body is designed in such a way that the illuminant, when supplied with electrical energy by the generator, emits light that is visible from outside the slat, in particular for a user of the trampoline.

[0008] For the purposes of this description, the jumping surface of the jumping mat is the area on which a trampoline user stands or jumps. The jumping surface is formed by the treads of the individual slats of the jumping mat. Accordingly, the tread side of a slat is the side of the slat on which the tread is located.

[0009] The jumping mat is movable at least in those places where slats are movably connected to other slats of the jumping mat at the fastening openings.

[0010] Slats on a jumping mat typically serve the purpose of providing a stepping surface for a user.

[0011] The invention includes the realization that a slat of the jumping mat is suitable for realizing further functions.

[0012] In particular, the invention includes the discovery that a slat is suitable for accommodating functional units and / or generating energy, e.g., housing a generator for generating energy. This includes the discovery that kinetic energy is supplied to the slats of a jumping mat during use. This supplied kinetic energy can be harnessed by a generator.

[0013] The invention includes the further finding that the lamella body of a lamella offers design flexibility that allows at least one receiving space to be arranged in the lamella body. According to the invention, a generator is arranged in the at least one receiving space, which generator is designed to convert at least a portion of the supplied kinetic energy into electrical energy. The supplied kinetic energy is thus converted into electrical energy by the generator directly in a corresponding lamella.

[0014] Energy generated by the generator can be used to supply electrical components with power via electrical lines. According to the invention, the generator is electrically connected to a light source which emits light when in generator mode. The kinetic energy supplied by a user jumping on the jumping mat is therefore advantageously first converted into electrical energy by a generator, and the generated electrical energy is in turn converted into visible light by a light source. The light source is arranged in such a way that emitted light is visible from outside the slat, so that a user can perceive the light while jumping on the jumping mat. Therefore, when a user jumps on a jumping mat which has a slat with a light element, the generator of the light element is advantageously driven by the vibration of the jumping mat and the light source is stimulated to glow.This can increase the attractiveness and play value of a trampoline and encourage users to jump on it. A user can, for example, change or adjust their jumping behavior on the trampoline according to the light effect created.

[0015] The supply of kinetic energy to a slat, the conversion of the supplied kinetic energy into electrical energy by a generator and the conversion of the electrical energy into visible light by a light source all have the effect that a trampoline user receives optical feedback on his physical effort through the generated light effect.

[0016] Particularly advantageous embodiments of the trampoline according to the invention are described below.

[0017] The trampoline according to the invention is particularly suitable for use as a play device in a playground. It is also suitable as a fitness or sports device, for example, in a gym.

[0018] In particularly preferred embodiments of the trampoline, the at least one generator comprises a coil and a permanent magnet. The coil of the generator is arranged relative to the tread surface of the slat such that the longitudinal axis of the coil is perpendicular to the tread surface of the slat. The permanent magnet is arranged inside the coil so that it can move along the longitudinal axis of the coil, so that when the jumping mat is deflected, the permanent magnet arranged inside the coil moves along the longitudinal axis of the coil and perpendicular to the tread surface of the slat. The permanent magnet arranged so that it can move relative to the slat and, due to its mass inertia, actually performs a relative movement with respect to the slat and in particular with respect to the coil of the generator when the slat is accelerated, for example, by jumping children or generally restoring elastic forces.The vertical arrangement of the coil relative to the stepping surface takes advantage of the fact that the momentum transferred to the jumping mat by a user's jump is greatest in the direction of the jump, i.e., perpendicular to the stepping surface. This means that the deflection of the jumping mat, and thus of the individual slats, is greatest in the direction of the jump due to the added kinetic energy.

[0019] A generator with a coil and permanent magnets has the advantage of not requiring a battery and can be manufactured without environmentally harmful metals. A generator with a coil and permanent magnets can be manufactured sustainably, is recyclable, and can typically be used to generate electrical energy for a relatively long period of time without maintenance.

[0020] The coil is preferably a wire coil, the wire of which is wound at a distance around the longitudinal axis of the coil. The coil is preferably an air-core coil, meaning the coil wire is not wound around a solid core, but rather a hollow cylindrical coil cavity is formed inside the coil. The coil can be self-supporting or formed by a non-magnetic coil carrier wound with coil wire. The coil of the generator is preferably arranged with respect to the tread surface of the lamella such that the longitudinal axis of the coil is perpendicular to the tread surface. This means that the base of a cylindrical coil is arranged parallel to the tread surface.

[0021] Preferably, a permanent magnet is arranged in the coil cavity formed inside the coil so that it can move along the longitudinal axis of the coil. This means that when kinetic energy is supplied to the generator, the permanent magnet can move back and forth along the longitudinal axis through the interior of the coil. Due to its inertia, the permanent magnet follows in its back-and-forth movement, in particular, a movement of the slat in which the light element with the generator is arranged. Therefore, when a user jumps on a trampoline mat that has such a slat with a light element, the kinetic energy supplied by the user can be at least partially absorbed by the permanent magnet in the coil. The permanent magnet then, in turn, performs a linear movement along the longitudinal axis of the coil.By moving the permanent magnet inside the coil, the magnetic flux density changes locally, inducing an electrical voltage in the coil according to the principle of electromagnetic induction. The generator described here, with a coil and permanent magnet, therefore functions as a linear generator, converting the kinetic energy of the linearly moving permanent magnet into electrical energy.

[0022] According to the invention, the object stated at the outset is achieved by a jumping mat according to claim 2, which is formed from movably interconnected slats, wherein the slats form a jumping surface of the jumping mat. The slats of the jumping mat each have a slat body with at least two fastening openings and are movably connected to further slats of the jumping mat at the fastening openings. The slats have a tread surface on one step side, and the tread surfaces of the movably interconnected slats form the jumping surface. At least one of the slats has at least one receiving space in which at least one light element is arranged. The light element comprises at least one generator for converting kinetic energy into electrical energy and at least one illuminant electrically connected to the generator.The generator is arranged and designed such that, in the event of a deflection of the jumping mat, it transfers electrical energy to the lamp, causing the lamp to emit light. The lamp is arranged such that its glow is visible from outside the slat.

[0023] The jumping mat according to the invention can be used particularly advantageously as a component of a play device for a playground. The jumping mat according to the invention can also be used indoors, for example as a component of a fitness or sports device in a fitness studio or as a component of a play device in a Indoor -Playground. The jumping mat according to the invention is particularly preferably a component of the trampoline according to the invention.

[0024] When a user jumps on the jumping mat, the generator can absorb at least a portion of the kinetic energy supplied by the user and convert it into electrical energy. The electrical energy generated by the generator is then transferred to the light source, which converts it into visible light. Advantageously, the light source is arranged such that the light emitted by the light source is visible from the outside, in particular to a user of the jumping mat. The emitted light can then be perceived by a user of the jumping mat while jumping on the jumping mat. The deflection of the jumping mat, the driving of the generator, and the emission of light combine to ensure that a user receives different optical feedback, for example, for different jumps.

[0025] Particularly advantageous embodiments of the jumping mat according to the invention are described below.

[0026] In particularly preferred embodiments of the jumping mat, the at least one generator comprises a coil and a permanent magnet. The coil of the generator is arranged relative to the tread surface of the slat such that the longitudinal axis of the coil is perpendicular to the tread surface of the slat. The permanent magnet is arranged inside the coil so that it can move along the longitudinal axis of the coil, so that when the jumping mat is deflected, the permanent magnet arranged inside the coil moves along the longitudinal axis of the coil and perpendicular to the tread surface of the slat.

[0027] During a jumping contact, especially after a user pushes off the jumping mat, the applied kinetic energy typically spreads in a wave-like pattern from the point of contact toward the edge of the jumping mat. If a jumping mat has multiple slats with integrated lighting elements, this can create an optical wave effect, meaning the lights in the individual slats are stimulated to glow at different times. This lighting effect can further contribute to the attractiveness of the trampoline as a piece of sports equipment.

[0028] For example, a jumping mat can have multiple slats with integrated light elements, with the slats with light elements arranged in a radial arrangement within the jumping mat. For example, the multiple slats with integrated light elements can each be arranged in beams emanating from the center of the jumping mat. If a user jumps on the jumping mat so that the jumping contact is in the center of the jumping mat, an optical wave effect can be created in which the slats of a beam emit light one after the other, emanating from the center.

[0029] The slats of the jumping mat can be the same color or, within a jumping mat, can be designed in different colors to create a motif or pattern. The jumping mat can also include slats with transparent slats. If a motif, such as a rocket or a skull or similar, is created through a targeted arrangement of slats with light elements in a jumping mat, this motif only becomes visible through the application of kinetic energy, i.e., by jumping on the jumping mat.

[0030] In order for a light element to illuminate, the permanent magnet must move relative to the coil due to its inertia inside the coil in such a way that its relative movement is converted into electrical energy sufficient to illuminate the light element.

[0031] A jumping mat can also have several slats with integrated light elements, each of which reacts differently to accelerations and, in particular, each has different acceleration thresholds.

[0032] For example, the light elements of different slats can each have permanent magnets with different masses, so that depending on the mass, different accelerations are required for the light element to light up.

[0033] The relative deflection of a permanent magnet inside a coil, which occurs in response to an applied acceleration, can also be adjusted by a spring which is arranged together with the permanent magnet inside the coil in such a way that the spring is compressed by the relative deflection of the permanent magnet and resets.

[0034] For a generator with a spring, a permanent magnet, and a mass, the generator's acceleration threshold is determined by the spring constant of the spring and the mass of the permanent magnet. This means that to specify a specific acceleration threshold, the spring constant of the spring and / or the mass of the permanent magnet can be selected accordingly.

[0035] Accordingly, light elements with different acceleration thresholds can be realized by having permanent magnets with the same mass but springs with different spring constants.

[0036] In the same way, light elements with different acceleration thresholds can also be realized by having the light elements each have springs with the same spring constant but permanent magnets with different masses.

[0037] A user of a jumping mat with slats whose light elements each have different acceleration thresholds can be encouraged to light up different slats of the jumping mat through different jumping variations. For example, a user might find it challenging to light up certain slats.

[0038] According to the invention, the object stated at the outset is achieved by a slat according to claim 3, which has a slat body with at least two fastening openings and a tread surface on a tread side. The slat has at least one receiving space in which at least one light element is arranged. The at least one light element comprises at least one generator for converting kinetic energy into electrical energy and at least one illuminant electrically connected to the generator. The generator is arranged and designed such that it converts supplied kinetic energy into electrical energy and delivers the electrical energy to the illuminant, such that the illuminant emits light. The illuminant is arranged and the slat body is designed accordingly that the illuminant's illumination is visible from outside the slat.

[0039] The slat according to the invention is particularly advantageously a component of the jumping mat of the trampoline according to the invention or of the jumping mat according to the invention. However, the slat according to the invention can also be used as a component of another piece of play or fitness equipment. The slat is particularly advantageously used as a component of a piece of equipment in such a way that kinetic energy can be supplied to the slat during use of the equipment. The slat is therefore advantageously a component of a movable element of a piece of equipment, for example, a jumping mat.

[0040] The generator is designed to absorb at least a portion of the energy supplied to the slat and convert it into electrical energy. The electrical energy generated by the generator is then transferred to the illuminant, which converts it into visible light. The illuminant is arranged such that the light emitted by the illuminant can be perceived from the outside, and in particular by a user who supplies kinetic energy to the generator.

[0041] Particularly advantageous embodiments of the lamella according to the invention are described below.

[0042] The receiving space can be open to the outside on at least one side. The light element arranged in the outer space is preferably accessible from the outside through the opening. The opening is preferably formed in an outer surface, and in particular in the tread surface. The receiving space then extends from the opening formed in the outer surface of the slat body into the slat body. The opening is preferably dimensioned such that the light element can be removed from the receiving space through the opening.

[0043] Preferably, the opening is a light exit opening formed in the tread surface. The light element is then arranged in the receiving space in such a way that the illuminant, when supplied with electrical energy by the generator, emits light toward the tread side of the slat through the light exit opening formed in the tread surface. If the slat is a slat of a jumping mat, a user of the jumping mat can directly perceive the light emitted through the light exit opening.

[0044] The opening can also be a light exit opening formed in an outer surface of the slat body opposite the tread surface. The light element is then preferably arranged in the receiving space such that the illuminant, when supplied with electrical energy from the generator, emits light toward the side of the slat opposite the tread side through the light exit opening formed in the outer surface. If such a slat is part of a jumping mat, a user of the jumping mat can indirectly perceive the light emitted through the light exit opening, for example, by illuminating a cavity beneath the jumping mat.

[0045] Preferably, a light element arranged in a receiving space is mechanically fixed in the receiving space. Mechanical fixation can be achieved by encapsulating or gluing the light element into the receiving space, or by having a housing configured such that the light element and housing are fixed in the receiving space by a positive fit.

[0046] In one embodiment, the light element is cast into the slat body and completely enclosed by the slat body. The slat body then preferably has no opening. The material of the slat body is then preferably at least partially transparent.

[0047] The lamella body preferably has an elongated shape. However, it is also conceivable for the lamella body to have a round or cylindrical, in particular disc-shaped, shape.

[0048] A longitudinally stretched slat body preferably has a length of between 5 and 16 centimeters, a width of between 1 and 7 centimeters, and a depth of between 1 and 7 centimeters. It can be advantageous if the width and depth of a slat body are essentially identical. In some design variants, however, it can also be advantageous if the width and depth of a slat body differ from one another. For example, a width can be 5 to 7 centimeters and a depth 2 to 3 centimeters. For example, it can be advantageous to enlarge the tread surface of a slat body by choosing a comparatively large width. However, the depth can still be selected to be comparatively small in order not to unnecessarily increase the weight of the slat.

[0049] With regard to the tread surface of the slat, it is particularly advantageous to define symmetry planes of the slat body: The slat body is preferably symmetrical to the vertical longitudinal plane perpendicular to the tread surface of the slat. Longitudinal planes are the planes that encompass the longitudinal axis of the slat body.

[0050] Preferably, one of the two fastening openings is located at each of the two longitudinal ends of the elongated slat body. The fastening openings are preferably aligned parallel to one another and extend in a horizontal longitudinal plane, wherein the horizontal longitudinal plane is aligned parallel to the tread surface. Preferably, the fastening openings are arranged symmetrically in the horizontal longitudinal plane along the height of the slat body, i.e., the distances from a fastening opening to the tread surface of the slat and to the side of the slat body opposite the tread surface are equal.

[0051] Preferably, the slat body has an elongated shape and the at least two fastening openings of the slat body are formed by through-openings which run parallel to the tread surface and through the slat body, wherein the through-openings are each arranged at the two longitudinal ends of the elongated slat body and run parallel to one another.

[0052] Furthermore, the slatted body is preferably symmetrical to a transverse plane that runs parallel to the cross-sectional area of ​​the slatted body and exactly centrally between two fastening openings arranged at the longitudinal ends of the slatted body. This transverse plane is thus aligned perpendicular to the jumping surface of a jumping mat and runs exactly perpendicular to the horizontal and vertical longitudinal planes.

[0053] Slats that exhibit the aforementioned symmetry properties make it particularly easy and quick to produce a jumping mat for a trampoline. Furthermore, such slats are comparatively robust and therefore relatively durable, even with regular use in a playground.

[0054] Since the electrical energy for stimulating a light source is generated by the generator, it is advantageously not necessary to integrate a battery or accumulator into the light element, which would have to be replaced or recharged after a certain period of time.

[0055] The light source preferably comprises a light-emitting diode (LED). LEDs can be provided that emit white, green, blue, red, or another color of the visible spectrum. An LED of the light source can be manufactured in various LED designs, for example, as an LED module with multiple LEDs on a circuit board or as a flexible LED strip.

[0056] The illuminant can also comprise at least one LED with an integrated control module, e.g., with a microchip, wherein the control module is configured to control the LED in at least one of different lighting modes. In particular, the control module can be configured to control one LED sequentially in different lighting modes. The control module can also be configured to control multiple LEDs jointly in one of different lighting modes.

[0057] The different lighting modes may include a flickering mode in which the LED is controlled by the control module so that the intensity of the emitted light changes regularly or irregularly over time to achieve a flickering effect.

[0058] The different lighting modes can also include a flashing mode in which the LED is switched on and off by the control module at a defined frequency, so that a flashing effect is achieved.

[0059] The different lighting modes may also include a two-color mode, in which the LED is controlled by the control module so that the LED emits light alternately in one of two different colors to create a two-color effect.

[0060] An RGB LED can also be used, which is formed by an LED module with a red, green, and blue LED. The light emitted by an RGB LED can be perceived by an observer as white light or as light of a different color, depending on the mixture of the light emitted by the individual LEDs. For example, light in a specific mixed color can be generated by specifically controlling the individual LEDs. A control module, e.g. a microchip, can be provided to control individual LEDs of an RGB LED. The control module can be designed to control the individual LEDs of the RGB LED in a color-changing mode such that the color of the light emitted by the RGB LED changes smoothly between different mixed colors, thus achieving a color-changing effect.For example, the control module can be configured to control the RGB LED such that light is emitted successively in different colors in a specified color sequence. The control module can be configured to control the RGB LED such that the color sequence is repeated several times in succession.

[0061] An LED with an integrated control module typically has a similar design to an LED without a control module, so that a slat described here can generally equally have an LED with an integrated control module or an LED without a control module or even an LED with an integrated control module and an LED without a control module at the same time.

[0062] When a slat with a light element, which has an LED with an integrated control module, is integrated into a trampoline jumping mat, a user can create a variety of unexpected and impressive lighting effects by jumping on the trampoline and is thus encouraged to use the play equipment intensively.

[0063] The light source can also be an SMD ( surface-mounted device ) LED or a COB ( chip on board ) LED.

[0064] Preferably, the light element is enclosed in the receiving space with a transparent potting material so that the light element is encapsulated in a watertight manner and the light emitted by the illuminant can be transmitted through the potting material.

[0065] The slat body can be made of a light, translucent material so that the light from the light source is visible from outside the slat. The material can also be only transparent to the extent that light is scattered within the material to such an extent that the light element itself is not visible from the outside or is only vaguely visible. A slat made of this type of material does not initially reveal that it contains a light element with a generator and a light source. Only when kinetic energy is supplied to the slat, and in particular to the generator, which converts this energy into electrical energy and transfers it to the light source, does a user recognize that the slat has a light element based on the light emitted by the light element. The lighting effect then occurs relatively unexpectedly for the user.

[0066] The at least one generator can have a coil and a permanent magnet. The permanent magnet is then preferably arranged inside the coil so as to be movable along the longitudinal axis of the coil and, by moving along the longitudinal axis inside the coil, induces a voltage in the coil by means of electromagnetic induction. The permanent magnet moves in a straight line along the longitudinal axis inside the coil. This advantageously creates a linear generator. The movement of the permanent magnet follows, in particular, the movement of the slats. By supplying kinetic energy, for example through a user's jumping contact on a jumping mat, the permanent magnet inside the coil generally performs a damped oscillation. The permanent magnet therefore moves back and forth inside the coil along the longitudinal axis until it reaches a rest position again. This causes the light to illuminate for the duration of the damped oscillation.

[0067] Preferably, the generator with the coil and the permanent magnet arranged inside the coil is arranged in the at least one receiving space of the slatted body such that the longitudinal axis of the coil is perpendicular to the tread surface of the slatted body and the permanent magnet is arranged to be movable inside the coil perpendicular to the tread surface of the slatted body along the longitudinal axis of the coil, so that the permanent magnet, by supplying kinetic energy, moves inside the coil perpendicular to the tread surface along the longitudinal axis of the coil. By jumping on a jumping mat, a user generates an impulse which is transferred to the jumping mat, causing it to be deflected from its rest position. The impulse transfer is greatest in the jumping direction, i.e. perpendicular to the jumping surface. A slat as a component of the jumping mat therefore experiences an impulse which is greatest in the direction perpendicular to the tread surface.Thus, if the generator with a light element is arranged in the receiving space of a slat such that the longitudinal axis of the coil is perpendicular to the tread surface, the inert permanent magnet moves back and forth by supplying kinetic energy in the direction of greatest momentum transfer. The generator is preferably aligned in the receiving space of the slat body such that the possible momentum transfer to the generator is greatest by supplying kinetic energy in a direction perpendicular to the tread surface.

[0068] The permanent magnet is preferably made of the neodymium-iron-boron alloy. This alloy is characterized by its ability to generate particularly strong permanent magnetic fields. Such permanent magnets can therefore be relatively small in size to generate a specific magnetic field strength. However, the permanent magnet can also be made of other alloys such as cobalt-samarium, AlNiCo, hard ferrites based on barium, strontium, PtCo, CuNiFe, CuNiCo, FeCoCr, martensitic steel, or MnAlC.

[0069] The at least one light element can also have a capacitor electrically connected to the at least one generator and the at least one illuminant for storing electrical energy generated by the generator and for delivering the stored energy to the at least one illuminant. A capacitor can temporarily store electrical energy and deliver it to the illuminant over a period of time. The period of time during which the illuminant emits light can thus be extended relative to the period during which a light element without a capacitor emits light.

[0070] If the slat body has a light exit opening from which the receiving space extends into the slat body, it can be advantageous if the light exit opening is dimensioned such that a light element can be inserted into the receiving space through the light exit opening and removed from the receiving space. If the light exit opening is located in the tread surface of a slat, a light element can be easily replaced from the tread side, even if the slat is installed in a jumping mat, for example, as part of a trampoline.

[0071] The slat body can have at least one light exit opening formed in the tread surface and at least one further opening formed on the side opposite the tread side. In this embodiment, the at least one receiving space preferably extends through the slat body from the light exit opening to the opening in the slat body formed on the side opposite the tread side. The receiving space can be accessible from the tread side and the side opposite the tread side. However, the light exit opening is preferably smaller than the opening formed on the side of the slat body opposite the tread side. Advantageously, a light element arranged in the receiving space is therefore difficult for a user to access from the tread side.

[0072] In some designs, the light exit opening and the opening on the opposite side of the slat body are designed such that the light element can only be removed from the receiving space through the opening in the slat body on the side opposite the stepping side. Therefore, if a slat is part of a jumping mat, a light element can only be inserted or removed from the side opposite the jumping surface. This makes it difficult for a user to remove a light element from an already installed jumping mat.

[0073] The at least two fastening openings of the slat body are preferably formed by through-openings that run parallel to the tread surface and through the slat body. Preferably, one of the through-openings is arranged at each of the two longitudinal ends of a longitudinally stretched slat body. The through-openings preferably run parallel to one another. A through-opening is therefore formed at each of the longitudinal ends of the slat body. The through-openings are preferably aligned parallel to one another and run in a horizontal longitudinal plane that is aligned parallel to the tread surface of the slat. At the through-openings, slats can be connected to other slats by passing a rope, e.g. a wire rope or a rubber rope, through them in order to produce a jumping mat. The through-openings preferably have a diameter of between 4 mm and 8 mm, preferably 6 mm, in the radial direction.The wire rope can be, for example, a galvanized steel wire rope, preferably with a diameter between 3 mm and 5 mm, preferably 4 mm. A wire rope can be coated with a plastic sheath. The plastic sheath can be, for example, a polyethylene sheath.

[0074] The slat body of the slat is preferably made of plastic, for example polyamide, polypropylene, polyurethane, polyethylene or elastomers, or of metal, for example aluminum, or of wood or of a combination of plastic, aluminum or wood. Plastic slats can be produced particularly advantageously using 3D printing. Plastic slats are advantageously comparatively UV and temperature resistant and therefore comparatively robust and durable. A slat body formed from at least one of the aforementioned plastics can also be produced using injection molding. A closure element of a slat can also be manufactured using injection molding. The injection molding process, in particular, enables the production of slat bodies and closure elements in large quantities.

[0075] Preferably, the slat body of the slat is rigid. A jumping mat made of rigid slats is only movable at the points where the slats are movably connected. Rigid slats also result in a comparatively pronounced trampoline effect.

[0076] The at least one lighting element can comprise exactly one generator and a plurality of light sources electrically connected to the generator, so that a plurality of light sources are jointly supplied with electrical energy generated by the exactly one generator in generator mode. To increase the luminous efficacy per lighting element, it may be advantageous to supply a plurality of light sources with power generated by a single generator.

[0077] In a preferred embodiment, the slat body has an elongated shape and the tread of the slat has a lateral widening in one area of ​​the tread in relation to the elongated slat body. The tread of such a slat is therefore enlarged. If a slat with a widened tread is part of a jumping mat, the jumping surface is also enlarged at this point. This can increase a user's sure footing and therefore control during a jump. In addition, the widening of the tread makes it less likely that dirt or small parts, such as keys, will fall through gaps in a jumping mat. Such a jumping mat therefore needs to be dismantled less often in order to clean the cavity underneath the jumping mat or to retrieve small parts.Another advantage of widening a step surface is that a motif incorporated into the jumping mat appears more striking by closing gaps in the jumping mat.

[0078] Preferably, the at least two fastening openings are arranged at each of the two longitudinal ends of the longitudinally stretched slat body. The area of ​​lateral widening of the tread surface is then preferably located between the fastening openings arranged at the longitudinal ends. Therefore, the tread surface is preferably not widened at the points where the slat is to be connected to other slats.

[0079] It can be advantageous if the tread surface of the slat body has a texture to increase slip resistance. Such a texture can be achieved, for example, with a dimpled GRIPTEQ ®< surface, which provides better grip.

[0080] The light element in the receiving space is preferably cast with a casting material. In particular, if a light element arranged in the receiving space is not cast, it can be advantageous to close an opening in the slat body with a diffuser. In one embodiment, a light exit opening formed in the tread is therefore closed by a diffuser. The diffuser is preferably designed to scatter light emitted by the lamp in the direction of the light exit opening. This can intensify the resulting lighting effect. The light emitted by the lamp can therefore be more easily perceived by a user. The diffuser can also illuminate the light exit opening completely, i.e. across its entire surface, which in turn can make the emitted light more easily perceived by a user.Preferably, the diffuser is made of a colored, translucent material so that the light emitted by the lamp is perceived by the user as a specific color. The use of differently colored diffusers is particularly interesting when a motif is to be incorporated into a jumping mat using slats with light elements.

[0081] Preferably, the diffuser comprises a material with fluorescent properties. This allows the material with fluorescent properties to emit light for a typically very short period of time, even after optical excitation. The light effect can thus be made more perceptible to a user, since light is emitted for a comparatively longer period of time overall.

[0082] In some embodiments, a slat comprises a slat body with at least two receiving spaces. In such embodiments, the receiving spaces can be separated from one another by a wall of the slat body. Alternatively, the at least two receiving spaces can also be connected to one another, i.e., the interconnected receiving spaces form a common, enlarged receiving space.

[0083] The slat can have exactly three receiving spaces, in each of which a light element is arranged. Preferably, each of the light elements comprises a generator and two light-emitting diodes that can be powered by the generator. The three receiving spaces can be separated from one another by a wall of the slat body or can be directly connected to one another. Preferably, each of the three receiving spaces extends from a respective light exit opening into the slat body. The slat body therefore preferably has three light exit openings. Each of the light exit openings preferably has a diameter of approximately seven millimeters. The three light exit openings are preferably formed in the tread surface of the slat body.Preferably, the slat body has three openings on the side opposite the tread side, so that each of the receiving spaces extends between one of the openings and an opposite light exit opening. Preferably, a light element can be removed from one of the receiving spaces only through an opening formed on the side opposite the tread side and not through a light exit opening formed in the tread surface. Due to the multiple LEDs, a quantity of light per slat can be emitted, particularly advantageously, that is comparatively easily perceptible to a user.

[0084] In a variant embodiment in which the slat has a slat body with at least two receiving spaces connected to one another, a light element can be arranged such that at least one generator of the light element is located in one receiving space and at least one illuminant electrically connected to the generator is located in another receiving space.

[0085] Preferably, at least one light element comprises exactly one generator and exactly one illuminant.

[0086] The slat can also have an elongated slat body with exactly three interconnected receiving spaces arranged along the longitudinal direction of the elongated slat body. Two light elements are preferably arranged in the receiving spaces such that a lamp of one of the light elements is located in the central receiving space, and a generator of the corresponding light element, electrically connected to a lamp, is located in a further receiving space adjacent to the central receiving space.

[0087] In particular, a lighting element can extend over three interconnected receiving spaces and have two generators, each electrically connected to two LEDs. The total of four LEDs are then preferably arranged in the middle of three interconnected receiving spaces, and one generator is arranged in each of the adjacent receiving spaces. The slatted body then preferably has a light exit opening in the tread surface, adjacent to the middle receiving space. The light exit opening preferably has a diameter of approximately 12 millimeters.

[0088] In some embodiments, one of two light elements is inserted into one of the two outer of three interconnected receiving spaces. Each of the two light elements preferably has a generator that is electrically connected to two light sources. The two light elements can also be separated from one another by an additional partition and simultaneously fixed in the corresponding receiving space by the partition. The two light sources of a light element are preferably arranged such that the generator is located between them. When the two light elements are inserted into the receiving spaces of the slat body, the total of four light sources are preferably arranged at regular intervals along the elongated slat body.In the tread surface of the slat body, there are then preferably four light exit openings with a diameter of preferably seven millimeters, each of which is assigned to exactly one of the four light sources and is arranged in such a way that light emitted by the assigned light source can be emitted through the corresponding light exit opening.

[0089] If a slat body has three interconnected receiving spaces, the slat body preferably has an opening on the side opposite the tread side, which extends over the three interconnected receiving spaces and through which one or more light elements can be removed from the receiving spaces.

[0090] A slat with an opening formed on the side of the slat body opposite the tread side preferably has a closure element. The closure element is then preferably attached to the slat body of the slat in such a way that a light element is sealed in a receiving space.

[0091] The slat can also have at least one receiving space in which several light elements are arranged. It can be advantageous to design a receiving space large enough to accommodate several light elements. In particular, such a slat can be manufactured with less effort than slats with several separate receiving spaces. A comparatively large receiving space can also be achieved by connecting several receiving spaces to one another, thus forming an enlarged receiving space.

[0092] At least one lighting element can also comprise exactly one generator and exactly one illuminant. Such a lighting element represents a particularly simple form of a lighting element according to one concept of the invention. The production of a lighting element with exactly one generator and exactly one illuminant also involves comparatively low production costs.

[0093] A lighting element can also have a housing which is arranged in the at least one receiving space of the slat and which houses the generator and the illuminant. The housing is then preferably made of a transparent material. Advantageously, the housing protects the generator and the illuminant from external influences. The housing is preferably shaped like a counterpart for a receiving space of a slat, so that the lighting element with housing can be inserted precisely into the receiving space and then mechanically fixed therein by a form fit. It is then not necessary to cast the lighting element in the receiving space in order to mechanically fix it.

[0094] The generator and illuminant of a lighting element can, for example, be encapsulated in a housing using a potting material. The potting material is preferably a UV-resistant plastic that is suitable for protecting the generator and illuminant from moisture. The potting material is preferably a polyurethane (PU)-based plastic. The housing can also be encapsulated in a receiving space of a slat body. Preferably, however, the housing is designed as a counterpart to a receiving space of a slat body, so that the housing inserted into the receiving space is mechanically secured in the receiving space by a positive fit.

[0095] A housing in the form of a counterpart for a receiving space of a slat can also be formed directly from a potting material. The housing formed by the potting material encloses the generator and the illuminant, preferably in a form-fitting manner. The potting material is preferably a polyurethane (PU)-based plastic. The housing formed by the potting material preferably has the external shape of a counterpart to a receiving space, such that it can be inserted into the receiving space in a form-fitting manner and then mechanically fixed therein. The housing formed by the potting material advantageously forms a closed housing in which the generator and illuminant of a lighting element are arranged and protected from external influences. The potting material used is preferably transparent to the light emitted by the illuminant.Preferably, a housing of a light element formed by the potting material is not itself potted in a receiving space, but is designed such that it is mechanically fixed in a corresponding receiving space by form-fitting.

[0096] At least one light element can also be encapsulated in the receiving space. After encapsulation, the light element is advantageously fixed in the receiving space of a slat and at the same time protected from external influences. Only a permanent magnet inside a coil is preferably not restricted in its movement inside the coil by the encapsulation. It is therefore advantageous to encapsulate a light element with a housing in the receiving space so that the generator and the light source do not come into contact with the material used for encapsulation. It is also conceivable that only the open sides of a coil carrier are closed with a cover so that a encapsulation material cannot penetrate into the coil carrier interior. Preferably, a material that is transparent to the light emitted by the light element is used for encapsulation.After encapsulation, the light element is advantageously sealed in a watertight manner and, in particular, requires comparatively little maintenance. In addition to or as an alternative to encapsulation, the at least one light element can be glued into the receiving space.

[0097] At least one light element can also comprise a damping element for acoustically dampening the generator. The damping element can, for example, be formed from a damping material such as a foam. The damping element can also have two magnets, one magnet being arranged near the tread side in the receiving space and the other near the side in the receiving space opposite the tread side, each with different magnetic poles to each other, and the generator being arranged between the two magnets. If the generator has, for example, a coil and a permanent magnet, and the permanent magnet is freely movable inside the coil along the longitudinal axis of the coil, magnets can be arranged above and below the coil such that the north pole of the permanent magnet meets the north pole of one magnet and the south pole of the permanent magnet meets the south pole of the other magnet.As a result, the permanent magnet and the corresponding magnets arranged above and below the coil repel each other magnetically, without any mechanical contact occurring during the permanent magnet's reciprocating movement. The permanent magnet is thus damped by the magnetic interaction with the magnets arranged above and below the coil.

[0098] Optionally, a slat can have a closure element. The closure element is then preferably arranged on an outer surface of the slat body such that the opening to the receiving space of the slat body is closed by the closure element. The closure element can protect a light element arranged in the receiving space from being removed or from external environmental influences. The closure element is preferably firmly connected to the slat body by a screw connection, an adhesive connection, or a cast connection.

[0099] A closure element can also have at least one receiving space, so that when the closure element is attached to the slat body, a light element is located with one part in the receiving space of the closure element and with the remaining part in the receiving space of the slat body.

[0100] Preferably, a closure element has a plurality of openings which, when the closure element is attached to the slat body, are arranged on the side facing away from the step side and are connected to a receiving space in the slat body. Rain and condensation, for example, which collects in the receiving space in the slat body, can drain through the plurality of openings in the closure element. A closure element with openings is also comparatively light. If several slats of a jumping mat have a closure element with openings, the overall weight of the jumping mat can be significantly reduced under certain circumstances. Comparatively little material is also required to produce a closure element with openings. Particularly when the total material used to produce a jumping mat is considered, the use of closure elements with openings can lead to significant material savings.

[0101] At least some of the slats of the jumping mat of the trampoline according to the invention or of the jumping mat according to the invention can be designed according to at least one of the previously described developments and variants of the slat according to the invention.

[0102] A light element as described above can also be used independently of the slat according to the invention and represents an independent subject matter of the invention. For example, a light element as described above can be integrated into a structural element of another gaming device or attached to the outside of the gaming device. Preferably, the structural element into which the light element is integrated or to which the light element is attached is one that is accelerated during use of the gaming device, wherein the kinetic energy causing the acceleration can be at least partially converted into electrical energy by the generator of the light element, so that the illuminant of the light element illuminates.

[0103] A light element as described above can, for example, be integrated into a structural element of a swing, a seesaw, e.g., a spring seesaw, or in particular a spring toy that accelerates during use. Alternatively, a light element as described above can be integrated into or attached to a turntable, a slide, or a carousel.

[0104] On one of the previously mentioned playground equipment but also on a suspension belt, also slackline A light element as described above can be attached externally. In particular, a suspended band is regularly deflected from its resting position during use, so that impressive lighting effects can be achieved with one or more light elements attached to the suspended band.

[0105] The trampolines described here, as well as other trampolines, can have slide-bearing springs as described below, from which a jumping mat is suspended within the trampoline frame. A slide-bearing spring as described in more detail below, particularly for a trampoline but also for other playground equipment, can also be implemented independently of the trampolines described here and, in particular, as a component of other playground equipment such as swings, climbing frames with movable elements, suspension bridges, etc., and represents an independent subject matter of the invention.

[0106] According to the invention, a slide-mounted spring, in particular for a trampoline, comprises: a fork holder with two fork arms, wherein the fork arms each have an opening for holding a bolt, a bolt which is held in the openings of the fork arms by the fork holder, a hollow shaft which is pushed over the bolt and arranged between the two fork arms, a spring suspension which is mechanically connected to the hollow shaft so that the spring suspension and the hollow shaft can move together relative to the bolt, and a spring, in particular a tension spring, which is fastened with one spring end to a spring suspension.

[0107] The invention incorporates the insight that in conventional trampolines, the jumping mat is typically suspended from a frame by tension springs. These tension springs are often hooked into openings in the frame. Due to the connection between the spring and the frame, the springs are regularly subject to significant wear, so that springs regularly break and require replacement.

[0108] In the slide-bearing spring according to the invention, the spring itself is not connected to a trampoline frame. Instead, the fork holder is connected to a trampoline frame, e.g. welded or screwed, or can already be designed as a component of a trampoline frame. The spring is connected to the spring suspension and this is connected to the hollow shaft, and the hollow shaft is slide-mounted on the bolt. The weak point of conventional trampolines, namely the contact point between the spring and the trampoline frame, is thus bridged with the slide-bearing spring according to the invention. The slide bearing can advantageously be designed to be significantly more robust than is the case with a contact point between the spring and the trampoline frame of a conventional trampoline. In a conventional trampoline, the contact point between the spring and the trampoline frame is typically subjected to approximately a point load.In the plain-bearing spring according to the invention, the contact point between the spring suspension with hollow shaft and bolt is advantageously designed in such a way that the forces occurring are distributed over a surface load.

[0109] Preferred embodiments of the plain-bearing spring according to the invention are described below.

[0110] The spring suspension is preferably made of metal, for example in the form of a sheet metal. The spring suspension can, for example, be formed by a sheet metal disc having two passages through which the spring is passed at one end. The two passages have a center-to-center distance that is matched to the diameter of the associated spring, so that a spring coil can be passed through both passages. After the spring has been passed through the passages of the spring suspension, the free end of the passed spring coil can be bent over to prevent the spring from winding out of the spring suspension. The spring suspension preferably has a further passage in which the hollow shaft is arranged. The hollow shaft is preferably mechanically fixed in the further passage of the spring suspension. The hollow shaft is pushed over the bolt to connect the spring to the fork holder.

[0111] The sliding bracket, the hollow shaft, and the bolt are preferably made of one metal. The sliding bracket, the hollow shaft, and the bolt can be made of different metals.

[0112] The hollow shaft preferably has a plastic coating on its interior, which slides on the bolt arranged in the hollow shaft cavity in the event of a joint deflection of the spring suspension and hollow shaft. The plastic coating prevents direct contact between the bolt and the metallic part of the hollow shaft, thus preventing metal-on-metal friction. The plastic coating can significantly reduce the resistance caused by sliding friction compared to metal-on-metal friction. The plastic coating can also reduce or completely prevent squeaking caused by metal-on-metal friction.

[0113] Preferably, the spring has, at its other spring end, a further spring suspension for attaching the spring to a wire rope of a jumping mat. For example, a wire rope of a jumping mat can have a loop with a thimble, i.e., a thimble crimp, to which the wire rope can be mechanically connected to the spring suspension. For example, the further spring suspension can have a hook-shaped passage for connecting the spring suspension to the wire rope. A hook-shaped passage for connecting the spring suspension to the wire rope can, for example, be designed as a bayonet lock.

[0114] The invention will now be explained in more detail using an exemplary embodiment with reference to the figures.

[0115] Figure 1schematically shows a trampoline 100 with a jumping mat 102. The trampoline 100 shown is particularly suitable for use as a play device in a playground. In the embodiment shown, the trampoline 100 has a rectangular shape. In various embodiments not shown here, a trampoline has a round shape or a rectangular shape deviating from the rectangular shape shown, or another polygonal shape. The trampoline 100 shown is also suitable for use as a module in a trampoline arrangement.

[0116] The trampoline 100 comprises a jumping mat 102 formed by slats 104 movably connected to one another, wherein the slats 104 form a jumping surface 106 of the jumping mat 102. The slats 104 each have an elongated slat body and a tread surface on one step side. The tread surfaces of the movably connected slats 104 form the jumping surface 106 of the jumping mat 102. In an embodiment not shown here, the slat body does not have an elongated shape, but rather a different shape. Instead of an elongated slat body, round or cylindrical, in particular disc-shaped, slat bodies can be used to form a jumping mat.

[0117] Each of the slats 104 has two fastening openings (not shown) through which a wire cable 108 is guided, so that the slats 104 are threaded onto wire cables 108. In an embodiment not shown here, the slats are threaded onto elastically stretchable cables, e.g., rubber cables. The slats 104 are threaded onto the cables 108 in such a way that the jumping mat 102 is characterized by a pattern of slats 104 arranged offset from one another. In each of the horizontal directions of the jumping surface 106, a gap thus borders each of the slats 104 of the jumping mat 102. The slats are made of plastic and are inherently rigid. The jumping mat 102 itself is therefore essentially movable at those points where the slats 104 are movably connected to one another.

[0118] At least a part of the slats 104, of which the jumping mat 102 of the trampoline 100 is formed, are like those with respect to Figures 3 , 4 ,5 and 6 described lamellae.

[0119] In particular, at least one of the slats 104 of the jumping mat 102 has a Figure 3 described slatted body with a receiving space (not shown) in which a light element (not shown) is arranged. The receiving space extends, as shown in Figure 3shown, starting from a light exit opening (not shown) formed in the tread surface of the slat body into the slat body. The light element comprises a generator for converting kinetic energy into electrical energy and a light source electrically connected to the generator. The light element is arranged in the receiving space such that the light source, when supplied with electrical energy from the generator, emits light in the direction of the tread side of the slat through the light exit opening formed in the tread surface. Light emitted by the light source thus exits through the light exit opening while a user is jumping on the trampoline 100 and can be perceived by the user, in particular while jumping.

[0120] At both ends of the ropes 108, loops (not shown) are arranged, from which the ropes 108 and thus the jumping mat 102 are suspended on tension springs 110, for example, helical tension springs. The tension springs 108 are attached to a frame 112, in particular a steel frame. The tension springs 108 hold the jumping mat 102 in an articulated position and are connected to the steel frame 112. The spring action of the jumping mat 102 thus results largely from the elastic properties of the tension springs 108. In an embodiment not shown here, in which rubber ropes are used instead of wire ropes, the rubber ropes are generally not attached to tension springs, and the spring action depends essentially on the elastic properties of the rubber ropes used. The trampoline 100 is particularly suitable for permanent installation on a playground.The steel frame 112 with jumping mat 102 is then preferably mounted over a cavity in the ground at ground level.

[0121] In an embodiment not shown here, a fall protection border is also provided, which is arranged above the frame and the tension springs. A fall protection border is intended to prevent a user from directly impacting the tension springs or the steel frame. A shock-absorbing floor covering, such as a poured granulate floor, is typically provided around a fall protection border to further reduce the risk of injury to a user.

[0122] Figure 2 shows a jumping mat 202, which is formed by movably connected slats 204. The slats 204 form a jumping surface 206 of the jumping mat 202. The jumping mat 202 shown can be particularly advantageously used as a component for a play device for a playground, for example for a Figure 1described trampoline.

[0123] The slats 204 of the jumping mat 202 each have an elongated slat body with two fastening openings (not shown) and are movably connected at the fastening openings to further slats 204 of the jumping mat 202. The slats 204 have a tread surface on one side, and the tread surfaces of the movably connected slats 204 form the jumping surface 206.

[0124] At least a part of the slats 204, of which the jumping mat 202 is formed, are like those with respect to Figures 3 , 4 , 5 and 6 described lamellae.

[0125] In particular, at least one of the slats 204 has a shape as described with respect to Figure 3described slat body with a receiving space (not shown) which extends from a light exit opening (not shown) formed in the tread surface of the slat body into the slat body. A light element (not shown) is arranged in the receiving space. The light element comprises a generator for converting kinetic energy into electrical energy and a light source electrically connected to the generator. The light element is arranged in the receiving space in such a way that the light source, when supplied with electrical energy by the generator in generator mode, emits light in the direction of the tread side of the slat through the light exit opening formed in the tread surface.Thus, when a user jumps on the jumping mat 202 and supplies kinetic energy to the jumping mat 202 through a jumping contact, a generator can absorb at least a portion of the kinetic energy supplied by a user and convert it into electrical energy. The electrical energy generated by the generator is then transferred to the light source, which converts it into visible light. The generated light can then be perceived by the user while jumping on the jumping mat 202.

[0126] Figure 3 shows a slat 300 with a slat body 302, which has a receiving space 308 in which a light element 318 is arranged. Figure 3 The lamella shown is particularly advantageous as a component of a Figures 1 and 2 described jumping mat.

[0127] The slat 300 comprises an elongated slat body 302 with a tread surface 304 formed on a tread side 306 of the slat body 302. A receiving space 308 is formed in the slat body 302, extending from a light exit opening 310 formed in the tread surface 304 into the slat body 302. In the embodiment shown, however, the receiving space 308 does not extend through the slat body 302. The side 312 opposite the tread side 306 accordingly has no opening.

[0128] The slat body 302 has two fastening openings 314, which are designed as passages through the slat body. One of the passages 314 is located at each of the two longitudinal ends 316 of the elongated slat body 302. The passages 314 run parallel to each other in a horizontal longitudinal plane, which is aligned parallel to the tread surface 304. At the passage openings 314, the slat 300 can be connected to further slats by passing a cable (not shown) through them, in order to form a Figures 1 and 2 to produce the jumping mat described. The slat body 302 of the slat 300 is made of plastic and is inherently rigid.

[0129] Arranged in the receiving space 308 is a light element 318, which comprises a generator 320 designed to convert kinetic energy into electrical energy. The light element 318 further comprises a lamp 322, which is electrically connected to the generator 320 and is supplied with power by the generator in generator mode. The electrical energy generated by the generator 320 is thus transferred to the lamp 322, which is converted into visible light by the lamp 322. The light is emitted in the direction of the light exit opening 310, so that the light can be perceived by a user.

[0130] In an embodiment not shown here, generator 320 includes a coil and a permanent magnet. The permanent magnet is arranged inside the coil so that it can move along the coil's longitudinal axis and, by moving along the longitudinal axis inside the coil, induces a voltage in the coil by means of electromagnetic induction.

[0131] In this embodiment, not shown here, the generator with the coil and the permanent magnet arranged inside the coil is arranged in the receiving space 308 of the lamella body 302 such that the longitudinal axis of the coil is perpendicular to the tread surface 304 of the lamella body 302, and the permanent magnet is arranged inside the coil so that it can move perpendicular to the tread surface of the lamella body along the longitudinal axis of the coil. When kinetic energy is supplied to the lamella 300, the inert permanent magnet moves perpendicular to the tread surface 304 along the longitudinal axis of the coil.

[0132] In an embodiment not shown here, the light exit opening 310 formed in the tread surface 304 is closed by a diffuser. The diffuser scatters light emitted in the direction of the light exit opening 310, whereby the light emitted by the illuminant 322 can be more easily perceived by a user due to the planar illumination of the light exit opening 310.

[0133] Figure 4 shows a slat 400 with a slat body 402 which has three receiving spaces 408, in each of which a light element 418 is arranged. Figure 4 The lamella described is particularly advantageously a component of a device as described in relation to Figures 1 or 2 described jumping mat.

[0134] The slat 400 comprises an elongated slat body 402 with a tread surface 404 formed on a tread side 406 of the slat body 402. Three receiving spaces 408 are formed in the slat body 402, spaced apart from one another along the longitudinal axis of the slat body 402, each extending from a light exit opening 410 into the slat body 402. However, the receiving spaces 410 formed in the slat body 402 do not extend through the slat body 402, so that the slat body 402 has no openings on the side 412 opposite the tread side 406.

[0135] The slat body 402 has two fastening openings 414, which are designed as passages through the slat body 402. One of the passages 414 is located at each of the longitudinal ends 416 of the elongated slat body 402. The passages 414 run parallel to each other in a horizontal longitudinal plane that is aligned parallel to the tread surface 404.

[0136] In each of the three receiving spaces 408, a light element 418 is arranged, which comprises a generator 420 designed to convert kinetic energy into electrical energy. Each of the light elements 418 further comprises a lamp 422, which is electrically connected to the respective generator 420 and is supplied with power by the generator in generator mode. Because multiple light elements 418 are provided in the slat 400, the jointly emitted light is comparatively easily perceptible to a user.

[0137] The tread surface 404 further features a texture 424, which is realized in the form of a dimpled GRIPTEQ® surface. The texture 424 provides the user with improved grip.

[0138] Figure 5 shows a slat 500 with an elongated slat body 502, which has three light exit openings 510 spaced apart along the longitudinal axis of the slat body 502 and three openings 511 formed on the side opposite the tread side. Figure 5 The lamella described is particularly advantageously a component of a device as described in relation to Figures 1 or 2 described jumping mat.

[0139] Between the respective openings 510, 511, a receiving space 508 extends through the slat body 502. A light element 522 is arranged in each of the receiving spaces 508, which comprises a generator 520 designed to convert kinetic energy into electrical energy. Each of the light elements 518 further comprises a lamp 522, which is electrically connected to the respective generator 520 and is supplied with power by the generator in generator mode.

[0140] In the embodiment shown, the light exit openings 510 are smaller than the openings 511 formed on the side 512 of the slat body 502 opposite the step side. Advantageously, the light elements 522 arranged in the respective receiving spaces 508 are therefore difficult for a user to access from the step side 506.

[0141] In the embodiment shown, the light exit openings 510 and the openings 511 formed on the opposite side 512 of the slat body 502 are designed such that a corresponding light element 522 can only be removed from the slat body 502 through the opening 511 of the slat body 502 formed on the side 512 opposite the tread side 506. In particular, a corresponding light element 522 can therefore only be inserted into or removed from the receiving space 508 from the side 512 opposite the tread side 506.

[0142] The slat body 502 has two fastening openings 514, which are designed as passages through the slat body 502. One of the passages 514 is located at each of the longitudinal ends 516 of the elongated slat body 502. The passages 514 run parallel to each other in a horizontal longitudinal plane that is aligned parallel to the tread surface 504.

[0143] In the embodiment shown, a closure element 524 is attached to the slat body 502 on the side 512 opposite the tread side 506. The closure element 524 closes the openings 511 of the slat body 502 formed on the side 512 of the slat body 502 opposite the tread side. The closure element 524 can protect the light elements 522 arranged in the receiving spaces 508 from being removed and from external environmental influences. In various embodiments not shown here, the closure element 524 is firmly connected to the slat body 502 by a screw connection, an adhesive connection, or a cast connection.

[0144] Figure 6 shows a plan view of a slat 600 with a laterally formed widening 612 of the tread surface 604 with respect to the elongated slat body 602. A slat as in relation to Figure 6The lamella described is particularly advantageously a component of a device as described in relation to Figures 1 or 2 described jumping mat.

[0145] The slat 600 comprises an elongated slat body 602 with a tread surface 604 formed on a tread side of the slat body 602. The slat body 602 has three receiving spaces 608 spaced apart from one another along the longitudinal axis of the slat body 602, each extending from a light exit opening 610 into the slat body 602.

[0146] The tread surface 604 of the slatted body 602 further comprises a widening 612 which extends centrally between two fastening openings (not shown) formed at one of the two longitudinal ends 616 of the elongated slatted body 602, wherein the fastening openings are formed according to the manner described with reference to Figures 3 , 4 , or 5described fastening openings. The area of ​​the lateral widening 612 of the tread surface 604 is therefore located between the fastening openings arranged at the longitudinal ends 616. At the locations of the fastening openings where the slat 600 can be connected to additional slats, the tread surface 604 is therefore not widened.

[0147] The treads 604 further have a structuring 614 which is designed in the form of a nubbed GRIPTEQ ®< surface.

[0148] Figure 7 shows a circuit for a light element 700 with a generator 702 and two light sources 704, which are designed as light-emitting diodes 706.

[0149] The generator 702 has a coil 708 and a permanent magnet 710. The permanent magnet 710 is arranged in the interior of the coil 708 so as to be movable along the longitudinal axis of the coil 708 and, by moving along the longitudinal axis inside the coil 708, induces a voltage in the coil 708 by means of electromagnetic induction.

[0150] When kinetic energy is supplied to the generator 702, the inert permanent magnet 710 inside the coil 708 is set in motion, and the kinetic energy of the permanent magnet 710 is converted into electrical energy by the coil 708. The electrical energy is transmitted in the form of a voltage to the two antiparallel-connected light-emitting diodes (LEDs) 706, which convert the electrical energy into visible light. The generated light can be emitted through a light exit opening of a slatted body (not shown here) and perceived by a user. The embodiment shown thus shows a light element 700 with two lamps 704, both of which are supplied with power by the same generator 702 in generator mode. This allows the light output per light element to be increased.

[0151] Figure 8shows a slat 800 with a slat body 802, which comprises a receiving space 808 in which a light element 818 is arranged. The receiving space 808 is arranged in the elongated slat body 802. The slat body 802 further has two fastening openings 814 and has a tread surface 804 on a tread side 806.

[0152] The light element 818 comprises a generator 820 for converting kinetic energy into electrical energy. When the slat 800 is part of a jumping mat and the mat is deflected, the kinetic energy supplied to the jumping mat can be partially absorbed by the generator and converted into electrical energy. The light element 818 also comprises a light source 822 electrically connected to the generator 820. When kinetic energy is supplied to the generator 820, the generator 820 converts it into electrical energy and outputs the electrical energy to the light source 822. The light source 822 converts the electrical energy into light. The light element 818 is arranged such that the illumination of the light source 822 is visible from outside the slat 800 and in particular to a user who supplies kinetic energy to the generator.Since the slat 800 has no opening through which the emitted light can be emitted, the slat body is preferably formed from a bright, translucent material so that the illumination of the illuminant 822 is visible from outside the slat 800. The material used is therefore at least partially transparent to the emitted light.

[0153] The slat 800, shown only schematically here, with a closed receiving space 808 in which a light element 818 is arranged, can be manufactured, for example, by injection molding. The light element 818 can, for example, be overmolded with a material and is then generally completely enclosed by the material. Preferably, an injection mold is used for this purpose, which already predetermines the external shape of the finished slat.

[0154] Figure 9shows a slat 900 with a slat body 902 comprising three interconnected receiving spaces 904, 906, 908. The receiving spaces 904, 906, 908 are designed such that one or more light elements (not shown) can be arranged therein. The receiving spaces 904, 906, 908 can then be closed or cast, for example, with a closure element (not shown), or first cast and then closed. The slat body 902 has fastening holes 914, which are provided so that a closure element can be fastened to the slat body 902 by means of a screw or plug connection.

[0155] The lamella body 902 has an elongated shape and, in the central region, has a lateral widening 910 formed with respect to the elongated lamella body 902. The lateral widening 910 is located between the two longitudinal ends 912 of the elongated lamella body 902. The lamella body 902 also includes two fastening openings (not visible in this view), each of which is arranged in one of the two sections between one of the longitudinal ends 912 and the region of the lateral widening 910 of the elongated lamella body 902.

[0156] The slat 900 shown here does not have an opening formed in the tread surface 916. Depending on the design of the lighting element to be used, the tread surface 916 may, for example, have four light exit openings arranged at regular intervals along the longitudinal direction of the elongated slat body or a comparatively large light exit opening arranged above the central receiving space 906. The light exit openings can be created by drilling into the tread surface as required.

[0157] Figure 10a) shows a top view of a light element 1000. In Figure 10b) is shown a side view of the same light element 1000. The light element 1000 is intended to be inserted into one of the three receiving spaces of the Figure 9 shown slat. In particular, a light element 1000 can be arranged in each of the two outer receiving spaces.

[0158] The lighting element 1000 has a generator 1002 and two lamps 1004 electrically connected to the generator 1002. The generator 1002 comprises a coil 1006 wound around a coil carrier 1008. A permanent magnet (not shown) is movably arranged in the interior of the coil carrier 1008. This means that when kinetic energy is supplied to the generator 1002, the permanent magnet can move back and forth along the longitudinal axis through the interior of the coil carrier and thus through the coil interior. By moving the permanent magnet inside the coil, the magnetic flux density for the coil changes locally, thereby inducing an electrical voltage in the coil according to the principle of electromagnetic induction. The coil 1006 is arranged in a central section of the coil carrier 1008.In the sections of the coil carrier 1008 where no coil 1006 is located, a damping material (not shown), preferably a foam, can be arranged in the interior of the coil carrier. The coil carrier 1008 is closed at each of its two base surfaces with a cover 1010.

[0159] The lighting means 1004 are designed as LEDs that are mounted on a carrier 1012. The carrier 1012 has an opening through which the coil carrier 1008 is guided up to the beginning of the coil 1006. The legs of the LEDs are guided through the carrier 1012 and are in electrically conductive contact with the coil such that a voltage induced in the coil 1006 can be transmitted to the LEDs. The carrier 1012 has a shape that allows it to fit precisely into a receiving space in the Figure 9 This allows the installation of the slat shown in Figure 9Three of the light elements 1000 shown here must be inserted next to each other in the slat shown.

[0160] When the light element 1000 is inserted into a receiving space, the coil 1006 of the generator 1004 is arranged with respect to a tread surface of a slat such that the longitudinal axis of the coil 1006 is perpendicular to the tread surface. The permanent magnet can then move freely within the coil interior perpendicular to the tread surface.

[0161] Figure 11a ) shows a plan view of a light element 1100 and Figure 11b ) shows a side view of the same light element 1100 arranged on a carrier 1102. The light element 1100 can be inserted into the three interconnected receiving spaces of the Figure 9 shown slat can be used.

[0162] The light element 1100 comprises two generators 1104, 1106, each of which is electrically connected to two of the four light sources 1108, 1109, 1110, 1111. The light element 1100 can therefore also be understood as two electrically independent light elements arranged on a common carrier 1102.

[0163] As with regard to Figures 10a) and 10b)As described, the generators 1104, 1106 each comprise a coil carrier 1112, 1113 with a coil 1114, 1115, in which a permanent magnet (not shown) is arranged. The coil carriers 1112, 1113 are each guided through an opening in the carrier 1102 up to the beginning of the coils 1114, 1115. The lighting means 1108, 1109, 1110, 1111, here LEDs, are arranged on the carrier 1102 between the two generators 1104, 1106. Conductor tracks 1116, 1117, 1118, 1119 are routed on the carrier 1102, establishing an electrically conductive contact between the LEDs 1108, 1109, 1110, 1111 and the coils 1114, 1115. The light sources are preferably LEDs and can be either single-color LEDs or RGB LEDs and can have an integrated control module to enable additional lighting effects.

[0164] If the lamp 1100 is inserted into the recording rooms of the Figure 9When the slat shown is inserted, the four LEDs 1108, 1109, 1110, 1111 are located in the central recording chamber, and one of the generators 1104, 1106 is located in each of the two adjacent recording chambers. The four LEDs 1108, 1109, 1110, 1111 can be identical, but can also be different, e.g., have different colors or include a control module for additional lighting effects.

[0165] Figures 12 and 13 show the same light element 1200 from different perspectives. Figure 12 shows a side view of the light element 1200 with housing 1202, which is formed from a potting material. In Figure 13 The light element 1200 with housing 1202 is shown in a plan view. The light element 1200 is as with respect to Figures 10a) and 10b)described and additionally comprises the housing 1202. The potting material from which the housing 1202 is formed is a transparent polyurethane-based plastic. The potting material encloses the coil carrier 1204 and the coil 1206 of the generator, as well as the two light sources (LEDs) 1208, in a form-fitting manner.

[0166] The housing 1202 formed by the potting material is designed in the form of a counterpart to a receiving space of a lamella body and a closure element, so that the housing can be arranged in a form-fitting manner in a receiving space and is then mechanically fixed therein.

[0167] On the side facing the tread side 1210 of a slat body, the housing has cylindrical elevations at the points where the light sources (LEDs) are arranged, which fit precisely into light exit openings of a, for example, Figures 21 and 22shown slat body. The cylindrical elevations preferably have a height that corresponds to the height of the light exit openings of the slat body formed in the tread surface, so that the cylindrical elevations are flush with the tread surface. Light emitted by the light element 1200 can then be emitted through the light exit openings and perceived by a trampoline user.

[0168] Figures 14, 15 and 16 show the same closure element 1400 from different perspectives. Figure 14 shows a plan view of the closure element 1400 and in particular of that side of the closure element 1400 with which the closure element 1400 is attached to a slat body of a slat in order to form a common receiving space. Figure 15 shows a side view of the closure element 1400. Figure 16shows a plan view of the closure element 1400 and in particular of that side of the closure element 1400 which faces away from the tread side of a slat body connected to the closure element 1400.

[0169] This in relation to Figures 14, 15 and 16 described closure element 1400 can, for example, be provided with a closure element as described in relation to Figures 21 and 22 described slatted body. To attach the closure element 1400 to a slatted body, holes 1402 for a screw connection are already provided at the two longitudinal ends of the closure element 1400.

[0170] The closure element 1400 has three interconnected receiving spaces, which together form an enlarged receiving space 1404. The side walls of the receiving space 1404 are designed in a shape that allows a light element to be arranged in a form-fitting manner in each of the three receiving spaces, without the arranged light element being able to slip into one of the adjacent receiving spaces. In particular, a light element can be arranged in each of the two outer receiving spaces, and the middle receiving space can remain free. For example, a Figures 12 and 13 The closure element 1400 can then be screwed to a slatted body as described with reference to Figures 21 and 22, so that the four lamps of the two light elements are each arranged under one of the four light exit openings of the slatted body as described with reference to Figures 21 and 22 described lamella body are arranged.

[0171] The closure element 1400 further has three openings 1406 on the side facing away from the tread side of a slatted body connected to the closure element 1400. Rainwater or condensate, for example, that has collected in the receiving space 1404 can flow out through the openings 1406.

[0172] Figures 17 and 18 show the same lamellar body 1700 from different perspectives. Figure 17 shows the slat body 1700 in a side view. Figure 18 shows the lamella body 1700 with a view of the side of the lamella body 1700 which is Figure 17 shown side. The lamella body 1700 has a through-opening 1702 at each of the two longitudinal ends of the longitudinally stretched lamella body 1700. As shown in Figure 17 As shown, the lamella body 1700 has convex centering cones 1704 adjacent to the through-openings 1702. On the Figure 18On the side of the lamella body 1700 shown, the lamella body 1700 has concave centering cones 1706 adjacent to the through-openings 1702, which are designed to receive convex centering cones of an adjacent lamella body, which are designed correspondingly to the convex centering cones 1704. The concave centering cones 1706 of the lamella body 1700 can thus movably engage the convex centering cones of an adjacent lamella body.

[0173] If adjacent lamella bodies each have convex and concave centering cones and are arranged such that the convex and concave centering cones of adjacent lamella bodies movably engage one another, the force applied can advantageously be distributed to the lamella bodies themselves and no longer primarily to the wire ropes that are routed through the openings. This reduces the mechanical stress on a wire rope caused by the force applied to a jumping mat, thus increasing its service life.

[0174] Convex centering cones 1704 and concave centering cones 1706 complementary to the convex centering cones 1704 can be provided in the slat bodies described here with receiving space for a light element, and in particular also in the slat bodies with respect to Figures 1 , 2 , 3 , 4 , 5 , 6 ,7 , 8 , 9 , 17 , 18 , 21 , 22 , 23 , or 24 described lamella bodies. However, convex centering cones 1704 and concave centering cones 1706 can also be provided in lamella bodies that do not have a receiving space for a light element, such as in relation to Figures 19 and 20 described.

[0175] Figures 19 and 20 show the same lamellar body 1900 from different perspectives. Figure 19 shows a plan view of the slat body 1900 of a slat without a receiving space for a light element, and in particular of the side of the slat body 1900 facing away from the tread surface 1902. Figure 20 shows a top view of the tread 1902 of the slatted body 1900.

[0176] The slat body 1900 does not have a receiving space intended to accommodate a light element. However, the slat body 1900 can be mechanically modified to accommodate a light element. As shown in Figure 19 As can be seen, the lamella body 1900 already has a receiving space 1904 which is divided by a web 1906. The web 1906 mechanically reinforces the lamella body 1900.

[0177] However, the bridge 1906 can be removed mechanically, so that, for example, as in Figure 22 The receiving space shown is created, in which at least one light element can be arranged. Light exit openings can also be incorporated into the tread surface 1902, e.g., light exit openings can be drilled into the tread surface 1902.

[0178] The lamella body 1900 is preferably not connected to a closure element.

[0179] A jumping mat can, for example, consist of a number of slats with a slat body without space for light elements, as in Figures 19 and 20 shown, and of a number of slats with a slat body with space for light elements, such as in Figures 21 and 22 shown, be educated.

[0180] Figures 21 and 22 show the same lamellar body 1900 from different perspectives. Figure 21 shows a plan view of the slat body 2100, which has four light exit openings 2104 formed in the tread surface 2102 and a receiving space 2106 for receiving at least one light element. Figure 22 shows a plan view of the slat body 2100, and in particular of the side of the slat body 2100 facing away from the tread surface 2102, so that the receiving space 2106 is visible. In Figure 22Furthermore, fastening holes 2108 of the slat body 2100 are visible, to which the slat body 2100 can be fastened, e.g. screwed, with a closure element, for example with a Figures 14, 15 and 16 described closure element. In the receiving space 2106 there are preferably two as described with respect to Figures 12 and 13 described light elements are arranged so that the illuminants of the light elements are arranged under the light exit openings 2104.

[0181] Figure 23 shows a slat 2300 with a slat body 2302 and with a closure element 2304 attached to the slat body 2302 in a side view. The slat body 2302 can, for example, be designed like the one described with reference to Figures 21 and 22 The closure element 2304 can, for example, be designed like the one described with reference to Figures 14, 15 and 16Preferably, the lamella body 2302 and the closure element 2304 have a common receiving space in which preferably two as described with respect to Figures 12 and 13 described light elements are arranged.

[0182] Figure 24 shows schematically illustrated slide-bearing springs 2400, which serve to suspend a jumping mat 2402 in a frame 2404 of a trampoline. As an example, the slide-bearing spring 2406 of the slide-bearing springs 2400 is shown partially disassembled to show the components of the slide-bearing springs 2400.

[0183] The plain-bearing spring 2406 includes a fork mount 2408 with fork arms for holding the bolt 2410. To be held by the fork arms, the bolt 2410 is pushed through openings in the fork arms. The bolt 2410 has a length dimensioned such that a portion of the bolt 2410 protrudes from the fork arm through which the bolt is pushed last. In the section of the bolt 2410 that protrudes from this fork arm, the bolt 2410 has a groove along the circumference of the bolt. When the clamp 2412 engages the groove of the bolt 2410 held in the fork mount, the bolt is fixed in the fork mount 2408. Before being fixed in the fork mount, the bolt 2410 is pushed through the openings of two plastic washers 2414 and a hollow shaft 2416. The hollow shaft 2416 is coated with a plastic in its interior so that the metal part of the hollow shaft 2416 is not in contact with the bolt 2410.The bolt 2410 is then movably mounted in the hollow shaft 2416 and slides on the plastic coating in the hollow shaft interior when the hollow shaft 2416 is deflected.

[0184] The spring 2418 is attached to a spring suspension 2420 at each of its spring ends. For attachment, the spring 2418 is guided at each of its spring ends through two openings in the corresponding spring suspension 2420. The spring suspensions 2420 are formed by sheet metal discs. Each of the sheet metal discs 2420 has a hook-shaped passage 2422. On the side facing the frame 2404, the spring 2418 is firmly connected to the hollow shaft 2416 by means of the spring suspension 2420, so that the spring 2418, spring suspension 2420, and hollow shaft 2416 move together. If the spring suspension 2420 is moved together with the hollow shaft 2416, the plastic coating in the interior of the hollow shaft 2416 slides over the bolt 2410. Since the plastic coating of the hollow shaft 2416 slides over the bolt 2410 due to the deflection of the jumping mat 2402, wear of the bolt 2410 can advantageously be reduced due to the comparatively low friction.Furthermore, squeaking noises typically occurring when jumping on the jumping mat 2402 can be largely prevented. In particular, the spring suspension 2420, by means of which the spring 2418 is attached to the hollow shaft 2416 and the bolt 2410, can also have a circular passage instead of the hook-shaped passage in which the hollow shaft 2416 is mechanically fixed.

[0185] At its spring end facing the jumping mat 2402, the spring 2418 is attached to the crimped end of the wire rope 2424 of the jumping mat 2402 by means of the spring suspension 2420.
