Definitions

  • the present invention concerns a gymnastic appliance of the type typically used in connection with performing jumping, trampoline or tumbling, wherein the gymnastic appliance includes a trampoline canvas with a periphery and a frame around the periphery of the trampoline canvas, wherein the trampoline canvas and the frame are substantially extending in the same plane, and wherein between the periphery and the frame of the trampoline canvas there are arranged a number of spring elements.
  • trampoline what is not common to the prior art trampoline types is how they are used and not the least the weight of the various users of the trampoline.
  • a mini-trampoline also known as a take-off trampoline
  • the trampoline is typically inclined, and the gymnast utilises it by running/jumping towards the trampoline canvas which then absorbs the force from the gymnast and returns the force so that he is assisted in the jump.
  • the trampoline canvas When speaking about e.g. big trampolines where a gymnast performs a series of jumps, the trampoline canvas is typically arranged horizontally. In certain cases with a big trampoline it may be so that the trampoline is more loaded in certain areas, in particular in the central area at the middle of the trampoline canvas, and as a consequence an increased load is also applied on the spring elements arranged between frame and trampoline canvas at the middle of the sides. When using big trampolines it has occurred many times that the trampoline canvas is pressed or stretched to such a degree that only a very modest distance to the floor is left under the trampoline. At the same time is observed that in particular the spring elements located at the middle of the frame sides are extended appreciably more than the spring elements closer to the corners of the trampoline.
  • the preferred types of spring elements are extension springs of the coil spring type, but elastic ropes are e.g. used in some types of gymnastic appliances/trampolines as well.
  • the present invention concerns a gymnastic appliance of the type typically used in connection with performing jumping, trampoline or tumbling, wherein the gymnastic appliance includes a trampoline canvas with a periphery and a frame around the periphery of the trampoline canvas, wherein the trampoline canvas and the frame are substantially extending in the same plane, and wherein between the periphery and the frame of the trampoline canvas there are arranged a number of spring elements.
  • the new feature of the gymnastic appliance according to the invention is that the spring elements are arranged in at least two zones, where one zone includes at least one first individual spring element, where the at least one first spring element has one total individual and non-adjustable spring characteristic, and where at least one second zone includes at least one second individual spring element, where at least one second spring element has at least one second total individual and non-adjustable spring characteristic.
  • a zone can in principle consist of a spring element, e.g. a coiled extension spring, having its own specific characteristic, but a zone can also consist of e.g. a series of two, three, four, five, six, seven, eight, nine or ten identical spring elements that may be arranged in a strategic way on the trampoline in relation to the points on the trampoline where the wear on the spring elements is the greatest, and/or in order to modify the total characteristic of the trampoline and thereby adapt the trampoline to a specific use, as described in more detail below.
  • a spring element e.g. a coiled extension spring
  • a spring element is to be regarded as a spring extending between frame and trampoline canvas and may in principle consist of an elastic rope which thereby constitutes a plurality of spring elements, or by other resilient devices by which the necessary elasticity/resiliency can be achieved.
  • the gymnastic appliance may include one type of uniform spring elements with a first spring characteristic along part of the periphery the gymnastic appliance, and along a second part of the periphery include a second type of uniform spring elements with a second spring characteristic.
  • a trampoline can therefore have tighter springs mounted along a front edge as seen in relation to the running direction of a gymnast using a take-off trampoline, whereas there are not so tight springs at the side edges, and a spring element with a third characteristic at a rear edge.
  • the invention concerns utilisation of springs with different properties on a trampoline where the springs are arranged in zones in selected areas along the periphery of the trampoline.
  • a side of a mini-trampoline is provided with springs with an alternative spring characteristic compared with the springs arranged on the remainder of the trampoline.
  • Such a mounting of spring elements may contribute positively to a gymnast's utilisation of the mini-trampoline when performing a jump.
  • an additional thrust in a certain direction can be achieved, having a significant effect on the take-off as the gymnast "stands" for a longer time in the trampoline canvas after jumping into the trampoline and before the take-off, thereby achieving the possibility of aligning his body position and performing the subsequent take-off and the exercise itself.
  • the additional effect is also due to the fact that the gymnast's run, which is horizontal, is more easily transformed into a thrust in the right direction, which is more precisely can be termed as "up and forward" when the spring action is not uniform at all sides of a mini-trampoline.
  • a trampoline according to the prior art i.e. a trampoline with identical spring elements at its sides - will deliver the force applied to it in the same direction as the one the force is coming from if the force is at right angles to the surface.
  • a trampoline is inclined, "ideal" and used as take-off trampoline for a gymnast running horizontally and jumping into the canvas of the trampoline with a horizontal force, the trampoline will transmit its force in a direction which generally corresponds to the incident angle of the force, only mirrored, and therefore onwards at a corresponding angle. In theory this corresponds to the physical situation where angle of incidence is equal to angle of reflection, of course in a theoretical and ideal situation.
  • a gymnastic appliance or a trampoline By adapting a gymnastic appliance or a trampoline with spring elements in zones, it can be adjusted how the force applied to a trampoline (the inwardly directed force) can be returned, and with regard to inclined trampolines, adjustment can be made regarding the direction of the inwardly directed force relative to the outwardly directed force.
  • a gymnast can hereby achieve a more efficient jump as his force can be applied more optimally in the take-off.
  • the total characteristic of the trampoline is changed such that the gymnast "stands" for a longer time in the trampoline canvas after landing and before the forward jump is executed.
  • the general purpose of differentiating the springs is to achieve special and desired properties of a gymnastic appliance/trampoline as the trampoline then can demonstrate properties adapted to the exercise or exercises performed on the trampoline. It may also be so that the choice of spring composition is adapted to the properties of a trampoline canvas in respective directions related to e.g. the weaving of the trampoline canvas.
  • a gymnastic appliance according to the invention can be designed such that the gymnastic appliance along at least part of the periphery the gymnastic appliance includes at least two different spring elements with at least two different spring characteristics, where respective spring elements are arranged mixed and in a regular order. It may be so that every other or third spring element is different from one or more other spring elements in a trampoline. Groups of uniform spring elements can be disposed between groups of other uniform spring elements, where spring elements in respective groups can be different. It may be so that in zones of a given size/length along a periphery on a trampoline are mounted differentiated springs. Such springs can be a classic coiled extension spring, though other types of springs can be used as well, including rubber springs and elastic cords, and other suitable spring elements.
  • a trampoline can e.g. be equipped with a plurality of spring elements along one side where the stiffness of respective spring elements increases towards the centre of the side of the trampoline, or where the stiffness/elasticity is determined to be symmetrical or asymmetrical in other ways along part of or along all of a periphery or a side of a trampoline.
  • a gymnastic appliance according to the invention can be a trampoline with a trampoline canvas where the trampoline canvas is substantially horizontal when the trampoline stands ready for use.
  • trampolines By this type of trampolines the user often has a tendency of moving away from the centre of the trampoline which in extreme cases can lead to accidents or injury if the gymnast cannot correct or is not timely correcting his jumps towards the centre point on the trampoline canvas.
  • This "travelling" on the trampoline can be counteracted by providing zones at the corners of the trampoline canvas where the springs have a spring characteristic different from that along the sides of the trampoline, preferably with a greater spring force,. These spring zones at the corners cause the gymnast in his jumping in the big trampoline to be "thrown” in towards the middle of the trampoline canvas.
  • a gymnastic appliance according to the invention can also be a trampoline with a trampoline canvas where the trampoline canvas has an inclination relative to horizontal when the trampoline stands ready for use.
  • the gymnastic appliance can have a frame and a trampoline canvas with a generally rectangular shape as seen on the plane in which frame as well as trampoline canvas extend.
  • Such a gymnastic appliance may advantageously be adapted such that along one side between frame and trampoline canvas, the gymnastic appliance includes one type of spring elements, and along at least two of the other three sides between frame and trampoline canvas, the gymnastic appliance includes a different type or several different types of with spring elements, e.g. the side in parallel with the first side, including springs with a third spring characteristic.
  • a gymnast can therefore optimise his jump due to the fact that the above change of the total characteristic of the trampoline is changed such that the gymnast "stands" for a longer time in the trampoline canvas after landing and before the forward jump is executed.
  • a gymnastic appliance according to the invention can also be a gymnastic appliance with a frame and a trampoline canvas with a generally circular shape as seen on the plane in which frame as well as trampoline canvas extend.
  • a frame and trampoline canvas there may, as already mentioned, be provided spring elements with several different spring characteristics which therefore can be more or less elastic/stiff.
  • zones of spring elements can be chosen according to general guidelines, calculations or philosophies, but may also be chosen for personal and individual reasons, including with regard to body weight, speed of running/jumping into the trampoline canvas, or due to various other reasons.
  • a gymnastic appliance according to the invention can be designed such that the gymnastic appliance includes at least one spring element constructed with at least one compression spring arranged in a spring housing, the spring housing including fixing means for fixation to the frame and to the trampoline canvas, and means for compressing the at least one compression spring when a pull is applied to the fixing means.
  • a spring housing does not necessarily be a closed housing in which is mounted one or more springs but may be constituted by any design or device by which it is possible to perform a compression of a spring element by a pulling action.
  • a compression spring is hereby used as an extension spring as the mentioned spring housing in principle converts the pull into a compression force on respective compression spring or springs.
  • Such compression springs can be coiled springs, an elastomer, disc springs, any mechanical, pneumatic or gas spring, or combinations thereof.
  • the mentioned spring types can also be used in an extension spring configuration.
  • one or more extension springs are arranged in a spring housing, the spring housing including fixing means for fixation to the frame and to the trampoline canvas, and means for pulling in the at least one compression spring when a tension is applied to the fixing means.
  • a gymnastic appliance may include at least one spring element designed with a progressive spring characteristic, where such a spring element is composed of several spring sub-elements.
  • a spring element can thus be composed of e.g. two compression springs with each their spring characteristic, together forming a progressive spring element.
  • One or more compression springs that are compressed by pulling in one or more extension springs can be applied as well, also resulting in a progressive spring characteristic.
  • the invention also concerns the use of springs with a specific spring characteristic and/or shape in respective zones. The shape of e.g. coiled springs can be selected such that the desired characteristics can be achieved, but such a desired spring characteristic may be achieved by other types of springs as well.
  • a spring element can therefore be coiled with diverging diameter and/or pitch, influencing the spring characteristic and the existence of progressivity or not.
  • a spring element can, as mentioned, be any yielding and elastic element that exhibit the desired properties, and the invention as such therefore does not concern a certain type of spring elements, though it is to be mentioned that coiled springs are traditionally preferred, but elastic ropes and hence all other types of spring elements can be used according to the invention.
  • the springs applied according to the invention are therefore not normally adjustable with regard to spring force, ensuring that the desired spring characteristic cannot be varied, and thereby that the characteristic of the trampoline cannot be changed except for the changes occurring by wear on the springs during use of the trampoline. This ensures that the spring characteristic peculiar to the springs in the individual zones on the trampoline cannot be changed substantially, and thereby that the above mentioned characteristics for the trampoline are maintained.
  • Fig. 1 appears a gymnastic appliance 1, here in the form of a rectangular trampoline including an external frame 2 and an internal trampoline canvas 3 fixed in the frame 2 by a number of spring elements 4 along the sides 5.

  • a gymnastic appliance 1 will probably not be configured in this way, and the Figure is therefore only to be regarded as an illustration showing different options. It is thus the intention with the Figure that each side of the trampoline shows different possibilities for different divisions of zones of the trampoline.
  • a rectangular trampoline 1 will typically be configured identically on two sides/ends 5 opposite each other.
  • Fig. 2 shows a gymnastic appliance 1 in the form of a circular trampoline where in a frame 2 is mounted a trampoline canvas 3 with a number of spring elements 4.
  • each spring element 4 is in principle a zone 6 as every other spring element 4 is with a different stiffness/spring characteristic, marked with different line thicknesses, where 6 is one type, while 6' is a spring with a different stiffness/spring characteristic.
  • a spring element 4 including a compression spring 7 in a spring housing 8, where the spring housing 8 has fixing means 9 for fixing on a frame 2 and to a trampoline canvas 3, as shown in Figs. 1 and 2 .
  • This variant of a spring element 4 is different from the classic extension springs as one or more compression springs 7 are used which via a pull in the spring housing 8 in direction of the arrow display a progressive spring characteristic. In Fig. 3 this is illustrated by the pitch of the compression spring 7 being different at the two ends. Progressive springs are known from other applications but have hitherto not been used in connection with trampolines.
  • Fig. 4 is seen yet a variant of a spring element 4 that includes a compression spring 7 in a spring housing 8.
  • this extension spring may advantageously be the stiffest of the two springs 7 and 10 as the extension spring 10 is only activated when the compression spring 7 has performed the work for which it is intended.
  • this extension spring may advantageously be the stiffest of the two springs 7 and 10 as the extension spring 10 is only activated when the compression spring 7 has performed the work for which it is intended.
  • other configurations are possible as well.
  • spring elements are coil springs, but other types, including elastomeric springs, gas and pneumatic springs, and any other possible type of spring and combinations thereof may be applied to a gymnastic appliance according to the invention.
