Definitions

  • the present disclosure relates to a trampoline mat according to the preamble of claim 1 and a trampoline comprising such a trampoline mat.
  • a trampoline comprises a trampoline mat, a frame and at least one resilient member.
  • the trampoline mat is typically circular, oval, square or rectangular.
  • the trampoline mat may comprise a cloth or net-shaped structure. It may be made of a polymeric material, such as polypropylene.
  • the frame is normally made of metal. It encompasses the trampoline mat and typically has substantially the same shape as the trampoline mat.
  • a circular or oval trampoline mat is then surrounded by a circular or oval frame having a larger diameter than the trampoline mat, and a square or rectangular trampoline mat is surrounded by a substantially square or rectangular frame, which however may comprise rounded-off edges.
  • the trampoline mat comprises a plurality of attachments distributed around the edge of the trampoline mat.
  • the attachments are adapted to receive one or more resilient members for retaining the trampoline mat under tension.
  • the resilient members may be a plurality of springs, e.g. helical springs, connecting the edge of the trampoline mat to the frame, thereby tensioning the trampoline mat.
  • the spring may be attached to a loop comprised in the attachment by means of a hook comprised in the spring.
  • the resilient member may comprise an elastic cord.
  • the elastic cord is long enough to go back and forth between the edge of the trampoline mat and the frame a couple of times. Each portion connecting the trampoline mat to the frame then forms a segment, which correspond to a spring in the above example.
  • the elastic cord may be so long, that only one elastic cord is utilized for the whole trampoline mat, or a plurality of elastic cords may be used.
  • the trampoline mat is often surrounded by an edge pad, which is adapted to at least partly cover the at least one resilient member and/or the frame. The edge pad will help preventing a user from stepping or landing between the resilient members, e.g. when climbing on to the trampoline mat.
  • the edge pad may also be arranged to cover the frame, thereby dampening a possible impact with the frame in case of stepping or landing on the frame.
  • the edge pad is often made as a number of segments, the shapes of which are adapted to the frame and the trampoline mat. For a circular or oval trampoline mat, the segments may therefore be arc-shaped. For a square or rectangular mat, rectangular segments may be used.
  • a number of support poles extending upwardly from the frame for carrying a protection, typically e.g. net, surrounding the trampoline mat in order to prevent a user from falling off the trampoline mat.
  • the protection may be attached to either the frame or the trampoline mat. Attaching to the frame results in a larger usable area of the trampoline mat. On the other hand, attaching to the trampoline mat helps to prevent the user from stepping or landing between the resilient members.
  • edge pad and/or surrounding protection there is still a risk that e.g. a foot or an arm of the user, e.g. if landing unfortunately in the vicinity of the edge of the trampoline mat, slips into the gap formed between the edge pad and the trampoline mat.
  • the foot or arm will, in such a case, come in direct contact with the resilient member and there is a risk of discomfort and even injury.
  • Document CN 201 147592Y discloses a trampoline, wherein the edge pad is provided with a circle of soft protecting-net or protecting-cloth. One end of the resilient member is attached to the frame and the other end is attached to the trampoline mat by passing through the soft protecting-net or protecting-cloth. Thereby the gap formed between the edge pad and the trampoline mat is covered by the protecting-net or protecting-cloth hanging down from the edge pad.
  • the proposed solution of CN 201 147592Y thus builds on cooperation between the trampoline mat, the protecting-net/cloth and the resilient member.
  • the object of the present disclosure is to overcome or ameliorate at least one of the disadvantages of the prior art, or to provide a useful alternative. It is desirable to provide a trampoline mat, which can help preventing injury if the user slips outwards over the resilient member. It is further desirable that the trampoline mat by itself can prevent injury, independently of other parts of the trampoline.
  • the object above may be achieved by the subject-matter of claim 1 .
  • a trampoline mat comprising a plurality of attachments distributed in the proximity of a circumference of the trampoline mat.
  • the attachments are adapted to receive one or more resilient members for retaining the trampoline mat under tension.
  • the trampoline mat has an upper side and a lower side.
  • the attachments are located on the lower side of the trampoline mat.
  • upper side and lower side relates to the trampoline mat in an unfolded state, e.g. the state it will have when mounted in the frame, in which it is retained under tension and thus is substantially flat when not in use.
  • the upper side of the trampoline mat is then the side which is intended for the user to jump on.
  • the attachments may be attached to or fixed to the lower side of the trampoline mat.
  • the attachments are preferably located at the lower side of the trampoline mat only, i.e. being inaccessible from the upper side of the trampoline mat.
  • the upper side of the trampoline mat thus forms a substantially flat surface.
  • the attachments may e.g. be sewn, welded, clamped and/or glued to the rest of the trampoline mat. If the trampoline mat according to an embodiment of the invention is circular or oval, the attachments are typically located in a circle or oval being concentric with the circumference of the trampoline mat, but having a smaller diameter.
  • the attachments are typically located parallel to, and inside of, the edge of the trampoline mat.
  • the terms inside of, outside of and outwards as used herein are intended to mean with respect to a centre of the trampoline mat.
  • the attachments By locating the attachments on the lower side of the trampoline mat it is made sure, that even if the foot or arm of the user would slip outwards out over the resilient member, it will not be injured by one or more of the attachments. Instead the foot or arm will slip on top of the trampoline mat, which at least partly covers the resilient member. The foot or arm will thus avoid direct contact with the attachments and the resilient members.
  • a spring as a resilient member
  • it is typically attached to a loop of the attachment by means of a hook, which constitutes a potential danger to a foot or arm slipping outwards over the resilient member.
  • the hook will be covered by the trampoline mat, thereby avoiding direct contact between the foot or arm with such a hook.
  • the trampoline mat according to the invention is independent of the edge pad.
  • the trampoline mat will protect a slipping foot or arm also in case no edge pad is present. If an edge pad is present, the trampoline mat is free to move independently of the edge pad.
  • the trampoline mat also works independently of the above-mentioned surrounding protection, e.g. a net, attached to support poles, which however may be used in addition.
  • the trampoline mat according to the invention may be used to retrofit existing trampolines by exchanging an existing trampoline mat to a new trampoline mat according to the invention.
  • the frame, resilient members and any edge pad/s or surrounding protection may then be re-used.
  • the trampoline mat according to an embodiment of the invention comprises a central portion being inside of the attachments and a peripheral portion being located outside of the attachments.
  • the trampoline mat may comprise a cloth or net-shaped structure, in particular in the central portion.
  • the cloth or net-shaped structure is used to provide a suitable surface for jumping.
  • the net-shaped structure differs from the cloth in that it has a higher open area.
  • the open area may vary from substantially zero for a dense cloth to close to 100% for a very open net-shaped structure.
  • the net-shaped structure is less slippery when wet.
  • the cloth is typically cheaper to manufacture than a net-shaped structure. It is further easier to produce in various shapes, such as circular or oval. It also provides higher comfort if the jumper falls than the net-shaped structure. The cloth is thus convenient for trampolines used by children.
  • the trampoline mat may be provided with an edge reinforcement at or adjacent to at least a portion of its circumferential edge.
  • the edge reinforcement will help to prevent damages to the edge, e.g. unravelling or fraying of the edge.
  • the edge reinforcement may comprise one or more seams, glue strings or a fold, a hem or material, e.g. a belt, seamed, welded and/or glued to the trampoline mat.
  • the trampoline mat extends outside of the attachments, preferably by at least 5 cm, more preferably by at least 15 cm and most preferably by at least 25 cm.
  • the exact measure of the extension outside of the attachments is preferably adapted to the size of the trampoline mat and/or the resilient members.
  • the size of the trampoline mat outside of the attachments may be adapted to the gap formed between the edge pad and the trampoline mat.
  • a trampoline mat used for competition i.e. sometimes heavily jumping
  • quite a big gap may be formed between the edge pad and the trampoline mat at the moment it is pressed down by the jumper.
  • peripheral portion of the trampoline is in one piece with the central portion of the trampoline mat. The same material is then used for both the central and the peripheral portions, which makes manufacturing efficient.
  • the peripheral portion is made as a separate unit, which is attached to the central portion, thereby forming the trampoline mat.
  • the two portions may then be made of two separate materials.
  • the central portion may in that case be a net- shaped structure suitable for heavy jumping, while the peripheral portion may be a cloth adapted to offer a good protection for the resilient members.
  • the material of the central portion may be adapted to be air permeable when it is moving up and down through the air, while the material of the peripheral portion may be adapted to provide a good protection of the resilient members.
  • the peripheral portion may be sewn to the central portion by at least one seam.
  • the two portions may be welded, glued or clamped together.
  • the two portions may comprise eyelets and a cord may run through the eyelets thereby connecting the two portions.
  • the attachments are located at a fold being formed in the trampoline mat, e.g. being sewn to the fold by at least one seam.
  • the fold may be located where the peripheral and central portions are attached to each other.
  • the attachment may comprise loops, e.g. made of metal, which are located at the lower side of the trampoline mat. The metal loop may be retained by an elongated piece of cloth going through the metal loop and being attached at both ends to the lower side of the trampoline mat.
  • the metal loop may be attached by a male and female connector being attached from either side of the trampoline mat, wherein the connector on the lower side of the trampoline mat retains the metal loop.
  • the attachment should be strong enough to hold the resilient member, also when it is tensioned.
  • it may alternatively be made of a polymeric material.
  • the attachments may be at least partly arranged between a belt and the lower side of the trampoline mat, the belt preferably extending in the proximity of a circumference of the trampoline mat.
  • the belt may be sewn over the attachments, using one, two, three or more seams. Preferably, the number of seams is in the range of 4 to 10.
  • the pre-tensioned length extension of the resilient member relates to the length of the resilient member, when the trampoline mat is held in tension by the resilient members in a deployed trampoline, and nobody is jumping or standing on the trampoline mat, such that the trampoline mat is substantially flat.
  • the resilient members will be stretched to a longer length extension.
  • the pre-tensioned length extension is preferably adapted to the size of the trampoline mat.
  • the pre-tensioned length extension may be in the range of 18-35 cm. This corresponds to about 15-25 cm for an untensioned spring, i.e. when no force is applied to the spring.
  • the trampoline mat is small, such as for an indoor trampoline, a so-called rebounder, the pre-tensioned length extension may be 5-10 cm.
  • the pre-tensioned length extension relates to the pre-tensioned length of a segment of the elastic cord connecting the attachment of the trampoline mat to the frame, and not to the whole length of the elastic cord.
  • the trampoline mat may further comprise a reinforcement, e.g. in the form of a cloth attached to the trampoline mat, overlapping at least a part of the peripheral portion, the reinforcement being located on the lower side of and/or the upper side of the trampoline mat.
  • the reinforcement may extend by at least 20%, preferably at least 40%, more preferably at least 60% and most preferably at least 80% of the pre-tensioned length extension of the resilient member.
  • the reinforcement may prevent wear of the trampoline mat.
  • the resilient member is attached to the outer end of the attachment, e.g. in the above-mentioned metal loop. Especially for the case a spring is attached to the loop by means of a hook, there is a risk of point-wise wear of the trampoline mat over the hook.
  • the reinforcement at least is located over the hook. If using a reinforcement, it will, at least partly, take the wear instead of the trampoline mat. The reinforcement will also distribute the weight if the user happens to step or land on top of the hook. The reinforcement may further help to stiffen the peripheral portion of the trampoline mat; thereby reducing the risk that the peripheral portion loses its shape.
  • the peripheral portion of the trampoline mat may comprise a padding on its upper side.
  • the padding may extend by at least 20%, preferably at least 40%, more preferably at least 60% and most preferably at least 80% of the pre-tensioned length extension of the resilient member.
  • the padding may be 0.5-2 cm thick.
  • the padding may act as a stop wall for a foot or arm sliding along the trampoline mat.
  • the trampoline mat may further comprise a first releasable fastening means at, or adjacent to, its circumference.
  • the first releasable fastening means is intended to cooperate with a second releasable fastening means attached to an edge pad, as described below.
  • the first and second releasable fastening means may be a hook and loop fastening means, a zipper, or one or more buttons.
  • the trampoline mat may extend by at least 10 cm, preferably at least 30 cm and most preferably at least 50 cm outside of the attachments, thereby allowing the peripheral portion to be at least partly folded.
  • the material of the peripheral portion is preferably selected such that it is suitable for folding. It may thus differ from the material of the central portion of the trampoline mat.
  • the first releasable fastening means is preferably located on the upper side of the peripheral portion after it has been folded. For example, if the peripheral portion is folded once, forming a V-shape, the first releasable fastening means is located on the lower side of the peripheral portion when it was still flat. As another example, if the peripheral portion is folded twice, forming a Z-shape, the first releasable fastening means is located on the upper side of the peripheral portion when it was still flat.
