Fold-up trampoline, method for folding up a trampoline and method for tensioning a jumping bed
View Patent ↗A fold-up trampoline, having at least three posts arranged in parallel to one another and to a vertical direction (V), wherein a jumping bed is tensioned between the at least three posts, at least three bracing struts which connect a respective other pair of posts arranged next to one another in a peripheral direction (U) of the trampoline and stabilize these posts in a horizontal direction (H), wherein each bracing strut is foldably mounted on both posts arranged next to one another in the peripheral direction (U) and has at least one central joint, which is provided in a central region (B 1 ) of the bracing strut, wherein all the posts arranged next to one another in the peripheral direction (U) can be moved towards one another in order to fold up the trampoline.
1. A foldable trampoline, comprising:
at least three posts arranged parallel to one another and to a vertical direction, wherein a jumping bed is tensioned between the at least three posts,
at least three bracing struts which each connect a different pair of posts adjacent in a circumferential direction of the trampoline to one another and stabilize said posts in a horizontal direction,
wherein each bracing strut is mounted so as to be foldable on the two posts adjacent in the circumferential direction and has at least one bracing strut central joint which is provided in a central region of the bracing strut, wherein all the posts adjacent in the circumferential direction is configured to each be moved toward one another in a horizontal direction in order to fold the trampoline, wherein the posts are always parallel to one another during a folding and unfolding movement of the trampoline.
2. The foldable trampoline according to claim 1 , wherein at least one central joint and at least two poles are provided, wherein each pole connects a different post to the central joint and is mounted so as to be foldable both on the corresponding post and on the central joint.
3. The foldable trampoline according to claim 1 , wherein the jumping bed is tensioned by at least one elastic element, wherein the elastic element is attached to at least one post and/or to at least one bracing strut.
4. The foldable trampoline according to claim 2 , wherein the at least one central joint and the tensioned jumping bed have a minimum distance in the vertical direction, where the minimum distance is greater than or equal to 20, 30, 40 or 50 cm.
5. The foldable trampoline according to claim 1 , wherein at least three securing rods are provided, which each connect a different pair of adjacent posts to one another and stabilize the posts in the horizontal direction, wherein each securing rod is mounted so as to be foldable on the corresponding post and has at least one securing rod central joint, which is provided in a central region of the securing rod and is used for folding the trampoline.
6. The foldable trampoline according to claim 1 , wherein the post has an upper section and a lower section, wherein the upper section is arranged above the lower section in the vertical direction, wherein a section joint is provided, via which the upper section is adapted to be pivoted relative to the lower section.
7. The foldable trampoline according to claim 5 , wherein a jump region for user is provided above the jumping bed in the vertical direction, wherein at least one central joint is provided below the jumping bed counter to the vertical direction and/or the securing rods are provided above the jumping bed in the vertical direction.
8. The foldable trampoline according to claim 1 , wherein a separate tensioning apparatus is provided for tensioning the jumping bed, wherein the tensioning apparatus acts independently of and/or dependent on the unfolding of the trampoline.
9. The foldable trampoline according to claim 5 , wherein joint securing means are provided on the bracing strut central joints and/or of the securing rod central joints in order to lock the bracing strut and/or securing rod central joints.
10. The foldable trampoline according to claim 1 , wherein a tensioner, designed as a motor or a crank, is provided for operating at least a part of the folding movement and/or the unfolding movement.
11. The foldable trampoline according to claim 5 , wherein a first Bowden cable system is provided, by which the unfolding of the trampoline is adapted to be operated, and/or a second Bowden cable system is provided, by which the folding of the trampoline is adapted to be operated.
12. The foldable trampoline according to claim 11 , wherein the first Bowden cable system and/or the second Bowden cable system are guided at least partially within one of the posts and/or a pole and/or a securing rod.
13. The foldable trampoline according to claim 11 , wherein at least one guide element is movably mounted in a bearing device within one of the posts and/or a pole and/or a securing rod, wherein the first Bowden cable system and/or the second Bowden cable system are guided via the guide element or are fixed to the guide element.
14. The foldable trampoline according to claim 11 , wherein the first Bowden cable system has an angled pole between one of the posts and the bracing strut, a pole and/or a securing rod, which angled pole, during unfolding of the trampoline, exerts a force in such a way that the bracing strut, the pole and/or the securing rod moves to the position in the unfolded state.
15. The foldable trampoline according to claim 1 , wherein the trampoline is adapted to be unfolded and/or folded via an exclusively translational movement of each post towards a central axis of the trampoline in each case.
16. A method for folding a foldable trampoline including structure according to claim 11 , comprising the steps of: operating the second Bowden cable system and at least indirectly bring about a folding of the bracing strut central joints and/or of the securing rod central joints and/or of the poles, wherein all the posts adjacent in the circumferential direction move toward one another.
17. The method for folding a foldable trampoline according to claim 16 , wherein the second Bowden cable system is operated and at least indirectly causes the upper section and the lower section of the posts of the unfolded trampoline to be pivoted from a coaxial position into a position in which they form a smallest angle of less than 180°, 90°, 45°, 20°, 10° or 5°.
18. A method for tensioning a jumping bed of a foldable trampoline according to claim 8 , comprising the steps of: tensioning the jumping bed via the separate tensioning apparatus during or after the unfolding of the foldable trampoline.
