  • FIG. 1 shows an embodiment of a trampoline 100.
  • the trampoline comprises a mat 101 , a frame 102, an edge pad 104 and a safety structure 105.
  • the edge pad extends over the border of the mat so that it covers the safety structure, and the safety structure is between the mat and the edge pad.
  • the edge pad comprises an upper surface of the edge pad, a lower surface of the edge pad, an internal side of the edge pad and an outer side of the edge pad.
  • the internal side of the edge pad is towards the centre of the mat and the outer side of the edge pad is away from the centre of the mat.
  • the outer side of the edge pad is above the frame or extends over the frame.
  • the mat comprises an upper surface of the mat, a lower surface of the mat, an edge of the mat, and a border (or a border area) of the mat.
  • the border comprises the edge of the mat and an area of the mat near the edge of the mat.
  • width of the border i.e. distance from the edge at right angles
  • width of the border is 10 cm or less. I any case, it is significantly less than width or length of the mat.
  • Figure 3 shows an example of an embodiment of a safety structure 205.
  • Figure 3 shows a cross section side view of a trampoline.
  • the trampoline comprises a mat 201 , a frame 202, an edge pad 204, and a multitude of resilient members 203.
  • the safety structure comprises a plurality of bump elements 251.
  • the safety structure comprises a skirt 252.
  • skirts are not needed.
  • the mat comprises an upper surface of the mat, a lower surface of the mat, an edge of the mat, and a border of the mat 211.
  • the edge pad has an upper side of the edge pad, a lower side of the edge pad, an internal side of the edge pad, and outer side of the edge pad.
  • the internal side of the edge pad is towards centre of the mat.
  • the resilient members are connected between the mat and the frame, and more specifically, the resilient members are connected to the edge of the mat.
  • the edge of the mat comprises holes or protrusions or similar arrangements for connecting the resilient members.
  • the edge pad is dimensioned in such a way that the internal side of the edge pad extends over the edge of the mat, i.e. the edge pad covers the area between the frame and the mat.
  • the bump elements 251 are elongated objects made of elastic material.
  • the bump elements are attached on the border 211 of the mat on the upper surface of the mat.
  • the bump element comprises an upper side of the bump element, a lower side of the bump element, an internal side of the bump element, and an outer side of the bump element.
  • the lower side of the bump element is towards the mat, and more specifically towards the upper surface of the mat.
  • the internal side of the bump element is towards the centre of the mat. Distance between the upper side of the bump element and the lower side of the bump element is height of the bump element.
  • the bump element further comprises a casing 254 for protecting the bump element.
  • the casing covers the bump element at least partly.
  • the casing fixes the bump element to the mat.
  • casings are not needed due to resistant material of the bump element.
  • the casing is for example cloth or fabric.
  • the bump elements 251 are positioned on the border 211 of the mat in such a way that the bump element is between the mat and the edge pad. This means that the upper side of the bump element and the lower side of the edge pad are in touch each other when the trampoline comprising the safety structure 205 is in use.
  • the edge pad 204 and the bump element have some distance between them in Figures 3 and 2.
  • the height of the bump element is such that the internal side of the edge pad 204 is above the mat 101 and a gap between the edge pad and the resilient members 103 is formed. The gap is dimensioned in such way that the resilient members are not in contact with the edge pad when the trampoline is in use. When the resilient members do not touch the edge pad when the resilient members stretch and contract, noises are significantly reduced.
  • the bump elements both warn users and stop body parts to slide under the edge pad.
  • FIG. 2 shows a cross section side view of an embodiment of a safety structure 105.
  • the safety structure comprises a bump element 151 , a skirt 152 and a multitude of auxiliary resilient members 153.
  • a mat 101 is kept in its place and in tension with a multitude of resilient members 103 that are connected between the mat and a frame 102.
  • the resilient members also provide the bouncing effect for the user of a trampoline.
  • the bump element 151 is embodied with a casing 154 made of cloth through which an elongated foam 155 is carried. Alternatively in some embodiments an elastic cord is carried through the casing to form the bump element.
  • the material used inside the casing is elastic so that it may bend and stretch when the trampoline is used, or when a user of the trampoline hits it. Also the cloth used for the casing need to be flexible like a lightweight mesh fabric.
  • the casing 154 of the bump element 151 is in this example sewn on the border 111 of the mat 101 from the internal edge of the bump element.
  • the sewing on the edge facing towards the centre of the mat prevents the bump element from rising when the mat is deflected during the use of the trampoline.
  • the bump element can be fixed on the border of the mat with a Velcro tape or similar arrangement so that it can be detached if necessary.
  • the safety structure in this example comprises a skirt 152 that is combined with the bump element 151 to inhibit a user from contacting the resilient members 103 or putting leg or hand between resilient members.
  • the skirt comprises an external edge and an internal edge.
  • the fabric used for the skirt is durable and the same or similar fabric that the fabric of the mat is used.
  • the skirt and more specifically the internal edge of the skirt, is sewn on the border 111 of the mat 101 with the same stitch as the bump element and is folded over the bump element. In some embodiments, it is sewn to the mat separately or to the casing 154 of the bump element.
  • the skirt extends between the resilient members and the edge pad so that more than half of the length of the resilient members are covered.
  • the safety structure in this example comprises the auxiliary resilient members 153 to connect the external edge of the skirt 152 to the frame 102.
  • the auxiliary resilient members comprise external ends of the auxiliary resilient members and internal ends of the auxiliary resilient members.
  • the auxiliary resilient members keep the skirt in place during the use of the trampoline.
  • the skirt with the auxiliary resilient members also helps to keep the edge pad 104 straight and above the resilient members 103 even if a user is stepping on it.
  • the external ends of the auxiliary resilient members are attached to the frame from top.
  • the fixing points of the auxiliary resilient members on the frame is above the level of the fixing points of the resilient members and the skirt is folded over the bump element so that it is above the mat 101 surface level. This ensures that there is a sufficient gap between the resilient members and the skirt to prevent noise generation during the use of the trampoline.

Abstract

L'invention concerne une structure de sécurité (105) pour un trampoline (100) comprenant un tapis (101), un cadre (102), une pluralité d'éléments élastiques (103) et un tampon de bord (104). La structure de sécurité comprend une pluralité d'éléments de bosse allongés (151) constitués d'un matériau élastique et disposés sur la bordure du tapis sur la surface supérieure où l'élément de bosse agit comme une limite qui avertit un utilisateur de ne pas se déplacer à l'extérieur de la zone de saut du tapis. L'élément de bosse est disposé sensiblement entre le tapis et le tampon de bord de telle sorte que le côté interne du tampon de bord est élevé au-dessus du tapis et des éléments élastiques pour réduire la génération de bruit pendant les sauts.
