Description

Trampoline and method of exercising

Field of invention

The present invention relates to trampolines, a method of exercising, a trampoline pole and a method of using the suspension of a trampoline pole.

Background to the invention

Trampolines have been described in the art. US 5624122 (Winkelhorn) discloses a trampoline field with two sets of parallel cables that cross each other and run from one to the other side of the trampoline field. The cables are attached to poles on each of the corners of the trampoline field. Panels are constructed of heavy fabric sheets. The unstable trampoline requires padding around each panel to cover the cables and springs, confining the bouncing space.

US2005130772 ( Levy) discloses hydraulic pistons to adjust the elasticity adjustment means.

GB 1056195 discloses a light weight, portable trampoline with a flexible frame to improve mat swinging. A wire connects the poles while a lower-placed tension wire provides inward and outward adjustments of the poles. The detachable connection of the rubber cords to the wire allows for sideway movement along the wire. The disclosed trampoline is flexible -and not rigid- while the cord movement will wear down the wire over time compromising the gymnast's safety. In fact, the entire trampoline will collapse upon breakage of the wire.

DE 195 35 693 discloses a portable trampoline with panels connected to a rigid frame that compromises the gymnast's safety. Pulling chain Kl and tension chain/wire K2 are placed below the plane of the panels respectively for folding the trampoline and for providing stability to the poles at both ends of the trampoline. Neither is connected to the resilient elements.

EP1038556 discloses a portable trampoline with multiple panels in a rigid frame that compromises the gymnast's safety. A chain or wire is mentioned but only for folding of the trampo line .

FR2684882 discloses a trampoline with a panel that covers an open concrete pit. The panel is attached with resilient elements to metal plates and to a cable that requires a cover to protect the padding. US5593368 discloses a trampoline with a lateral restraining mechanism to keep the gymnast away from the rigid frame of the trampoline. The mechanism involves a cable that is not connected or related to the resilient elements of the jumping panel. In fact, mechanism introduces even more rigid elements to the trampoline, potentially leading to more injuries.

FR 2844206 discloses a trampoline with panels and a solid bar. Bar (6) is supported by pivot (8), slide (9) and a suspension spring 10). In case a gymnast accidently hits the bar, the bar will descend upon the suspension, preventing injuries. When bouncing on the panel, the slide is locked with release pin (13). This pin however only moves - using an elastic intermediate- upon vertical movement of the panel, compromising the rigidity of the trampoline. Further, the proposed safety system actually fails when adjacent panels are being used at the same time.

FR2811901 discloses a trampoline with rigid frame that compromises the gymnast's safety and proposes an additional bar that extends outside the rigid frame. The additional bar unlocks moveable unit on to the suspension. However, the additional bar is not integrated into the pole, but extends beyond the perimeter of the trampoline field as it requires space to move downwards upon activation. This means that gymnast is not protected from injury when only hitting the rigid frame. Also, the proposed set-up requires activation of both suspension mechanisms at the same time to be effective, making this proposed safety feature undesirable.

There remains a need in the art for improved trampolines.

Summary of the invention

Surprisingly, we have found a way to improve trampolines and overcome one or more of the above or other problems of the prior art.

Detailed description of the invention

The trampoline device of the present invention comprises a trampoline field with at least one panel that is attached to and stretched within the trampoline frame with resilient elements. The frame and the resilient elements allow the panels to sufficiently stretched so that the panel can be used for bouncing. Trampolines can be used for exercising, such as gymnastics, gaming and/or fitness.

The present invention is in particular directed to a trampoline device comprising a frame with poles that are connected with chains wherein the poles are further interconnected with connecting bars. Preferably, these bars are located below the chains.

While the chains may be used to attach and stretch the panel, we have surprisingly found that the additional use of the connecting bars of the invention leads to better controlled trampoline jumps, reduced noise and less wear. Placement of the bars under the chain and outside the perimeter has been found to be beneficial as to avoid hitting the connecting bars. Surprisingly, we have also found that the invention also allows for stable construction of a tumbling lane, a panel that stretches from one side to the other side of the trampoline field without interruption or intermediate support structures that would interfere with the bouncing of the gymnast. In addition, integrity of the trampoline device of the invention is maintained while the use of the chain provides for enhanced safety when the gymnast does not land on the panel. The frame of the trampoline is rigid. Preferably, the frame is constructed of metal. Preferably, the frame comprises poles to provide a supporting structure for the trampoline with the panels. Preferably, the poles are rigidly interconnected with connecting bars. Preferably, the poles are interconnected with at least two connecting bars - an upper and a lower - to provide for further rigidity and thus forming a rigid rectangular open box frame with the poles extending upwards with the pole tops connected with a chain.

The poles of the frame are preferably vertical and placed in the line of the forces of gravity. Preferably, the poles are attached to the supporting floor with a bolt.

Preferably, the frame comprises side poles and corner poles and internal field poles. Depending on the number of panels and the set-up of the trampoline field, internal field poles are present, for instance a trampoline field with four rectangular panels has one internal field poles, 4 side poles and 4 corner poles. The bars of the frame of the invention are preferably rigidly connected to the poles of the frame, for instance fixed by welding or with bolts. Preferably, the bars are horizontal. Preferably, the bars are made of metal.

The internal field pole and the side poles (particularly on the side facing inwards of the frame) are preferably connected with a chain in the plane of the panel and outside the perimeter of the panel. Preferably, the chain is connected to the top of the pole. According to the invention, the poles are interconnected with connecting bars more preferably at least two connecting bars, an upper and a lower bar. The connecting bars are preferably located below the chains and preferably outside the perimeter of the panel. Preferably, the lower connecting bar is located near the underlying surface, more preferably up to 20% of the distance of the pole from the ground. The upper connecting bar is preferably located between the chain and the lower connecting bar, more preferably between 30 to 70% of the distance between the two. The lower placement of the horizontal connecting bars below the chain provides a safer bouncing experience for the gymnast.

The side and corner poles of the frame are preferably connected with a bar along the perimeter of the frame at the plane of the panels. Preferably, the side and corner poles are connected along the perimeter of the frame with a field side connecting bar, more preferably two field side connecting bars, an upper and a lower bar. Preferably, the upper field side connecting bar is connected to the top of the poles. Preferably, the side and corner poles are connected with a field side connecting bar at the plane of the panel to allowing for attaching the resilient elements thereto. Preferably, the side and corner poles are connected with a second field side connecting bar below the plane of the panel. We have found that such a frame exterior provides excellent bouncing characteristics. Preferably, the frame comprises internal field poles that are connected to at least three chains, more preferably 4 chains. Preferably, the internal field poles are connected to at least three connecting bars (preferably a set of 2 bars including an upper and a lower connecting bar), more preferably 4 connecting bars (preferably a set of 2 bars including an upper and a lower connecting bar). When next to a tumbling lane, the number of chains on the internal field poles is with one and the number of upper connecting bars on the internal field pole is also reduced with one. However, the lower connecting bar will still be present to provide rigidity to the tumbling lane construction. It will then be understood that, in case of two crossing tumbling lanes, the internal field poles on the corners will have two chains and two upper connecting bars but four lower connecting bars.

The invention relates to a chain. The chain preferably has ring that may have an external width of from 1 to 5 cm (for instance 2.5cm), an internal width of from 0.5 to 2 cm (for instance 1cm) and an external length of 1 to 7cm (for instance 5.5cm) and an internal length of 1 to 3 cm (for instance 2.5cm). Preferably, the chain provides a flexible tie with high tension strength. Use of the chain according to the invention increases the rigidity as well as the safety as compared to a sharp wire under tension. The resilient elements will not move sideways, resulting in more rigidity and less wear. Also, even when a chain breaks, the trampoline will stay in tact, while a trampoline constructed from wire would collapse under those circumstances, compromising the gymnast's safety. Further, the wire under tension can cut the padding or worse the gymnast. The panel (or bounce mat) of the present invention is used by the gymnast for jumping and bouncing upon. The panel is preferably made of fabric. Preferably, the panel is preferably positioned in a flat plane in the frame. The panel may have any shape, but is preferably selected from round and rectangular panels, more preferably rectangular panels. Preferably, the panels of the trampoline field are horizontal. Preferably, the panels of the trampoline side are at an angle to the trampoline field. Preferably, the panel is attached with resilient elements to the frame and more preferably to the chains internally in the trampoline field and to the field side connecting bar on the outside of the trampoline field.

The trampoline field preferably comprises at least 1 panel, more preferably at least 2 panels, most preferably at least 4 panels, and in particular at least 5 panels.

In a preferred embodiment, the trampoline of the invention comprises a trampoline field with at least one tumbling lane. Preferably, the trampoline field with a tumbling lane comprises at least 5 panels wherein one panel extends from one side of the trampoline field to the other side of the trampoline field. This tumbling lane is one continuous panel that extends beyond the size of the other panels. Preferably, the panel of the tumbling lane is connected with resilient elements to the chains that interconnect the poles that are located on the side of the tumbling lane. Preferably, these poles are also interconnected with bars below the plane of the panel, more preferably with 2 bars that run horizontal and parallel to the panel.
