Definitions

  • the invention relates to a bouncy cushion of the kind that comprises an inflatable casing comprising a circumferential wall, an upper side wall and a lower side wall.
  • Such cushions are typically made as a simple, airtight casing or cushion of plastic-coated mesh.
  • the casing is filled with air by means of a blower.
  • Comfort and safety during the use of inflated cushions as bouncy cushions is important. If a massive compression takes place in e.g. a first half of a conventional bouncy cushion, there is a risk that children standing somewhere else on the conventional bouncy cushion falls or are thrown off, and conventional bouncy cushions are often considered dangerous. Furthermore, the conventional bouncy cushion can often be compressed to such an extent that both walls of the bouncy cushion will be so close to the underlying hard base that children jumping on the bouncy cushion risk hurting themselves on impact.
  • the requirements to a safe bouncy cushion therefore include that a jumping person must not be able to compress the inflated bouncy cushion to an extent that has the effect that the person hurts himself during jumping-off or impact or that another jumping person accidentally is thrown off the bouncy cushion.
  • the novel and unique feature according to the invention is the fact that the upper side wall is connected to the lower side wall by means of a number of flexible threads or strips.
  • the structure according to the present invention is thus safer to use than known bouncy cushions and also provides a controlled trampoline effect.
  • the flexible threads or strips can be uniformly distributed and attached to the walls, in which case the load distribution on compression and relief of the bouncy cushion is correspondingly uniform.
  • the flexible threads or strips can be non-uniformly distributed.
  • groups of threads or strips can be distributed in a random pattern so that the pressure relief is distributed across the area of the bouncy cushion in a controlled but varied manner.
  • the walls of the bouncy cushion advantageously comprise at least one, mainly airtight outer layer and at least one inner layer, which inner layer is connected to the flexible threads or strips.
  • the at least one inner layer of both the upper side wall and lower side wall is made of a textile such as polyester fabric, in which loops of polyester thread traverse the opposite facing inner layers of polyester fabrics and thus connect the walls in a flexible and defined maximum distance from each other.
  • the maximum distance is defined by about half the length of the circumference of the loop, and the loops of polyester thread thus function as the flexible threads.
  • the flexible threads or strips are made of the same material as the at least one inner layer but within the scope of the present invention, the threads can also be made of another material than the inner layer.
  • the at least one outer layer must, as mentioned above, be made of a mainly airtight material, for example a plastic material welded or glued together with the at least one inner layer.
  • plastic layer examples can e.g. be polyvinyl chloride (PVC) or polyurethane (PUR) but other durable plastic materials that can be joined to the inner layer are also within the scope of the invention.
  • PVC polyvinyl chloride
  • PUR polyurethane
  • the invention is thus not limited to use of polyester for the inner layer but can use similar, flexible materials having corresponding tensile and breaking strength just as the flexible threads can be made of an elastic material, the elasticity of which is chosen so that the above compression and relief can be controlled. That is to say that the maximum elastic elongation of the flexible threads is defined by the length that a corresponding non-elastic flexible thread must have.
  • the number of threads keeping the upper side wall of the bouncy cushion connected to its lower side wall can vary but for a bouncy cushion having a thickness in the order of between 50 mm and 335 mm, there can for example be at least 5 threads per cm 2 , preferably at least 10 threads per cm 2 , but especially 20 threads per cm 2 .
  • an airtight zipper is inserted in at least one of the walls of the bouncy cushion, it will be easy to obtain access to the interior of the bouncy cushion. This is for example expedient when the bouncy cushion is to be repaired and when the bouncy cushion is to be emptied of air quickly.
  • the bouncy cushion can be inflated particularly easy if an air intake opening is made in at least one wall, said opening being arranged to be connected to an air supply source, for example a blower.
  • the number of joints is reduced to a minimum and thereby the risk of leakage.
  • Fig. 1 shows a bouncy cushion 1 on which a child 2 is jumping up and down.
  • the bouncy cushion 1 is made up of two lengths 1a, 1b of a double-walled starting material which will be described in more detail with reference to figs. 2a and 2b.
  • the two lengths 1a,1b are joined by joint 3, for example by welding or gluing.
  • the lengths 1a,1b are long continuous lengths that are folded to form the upper wall side 4, lower wall side 5, and circumferential wall 6a,6b,6c,6d of the bouncy cushion 1.
  • an airtight zipper 7 is mounted in the short end wall 6b of the circumferential wall 6, and an air intake opening 8 is made.
  • the air intake opening 8 can be fitted with e.g. a blind plug or non-return valve (not shown) to prevent air from blowing out.
  • the bouncy cushion 1 can also be provided with a pump or blower (not shown) maintaining a constant pressure in the bouncy cushion 1.
  • Figs. 2a and 2b show in greater detail in perspective how the double-walled starting materials 9;11 are constructed, and the constructions will be further explained with reference to figs. 3a and 3b.
  • Fig. 3a thus shows that the upper side wall 4 of the starting material 9 is made up of an inner layer 4a securely joined by means of for example gluing to an outer layer 4b and that the lower side wall 5 is made up of an inner layer 5a similarly securely joined to an outer layer 5b.
  • the inner layer 4a of the upper side wall 4 is located opposite the inner layer 5a of the lower side wall 5 and is connected to this by means of flexible threads 10.
  • the threads 10 are stretched to maximum extent as the bouncy cushion 1 is in its inflated and not-compressed state.
  • the stretched length of the threads 10 approximately defines the maximum internal distance between two opposite inner layers 4a,5a of the bouncy cushion.
  • the alternative starting material 11 shown in fig. 3b employs another kind of threads 12 for connecting the upper side wall 13 and the lower side wall 14 but is basically constructed in the same way as the starting material 9 shown in figs. 2a and 3a.
  • the upper side wall 13 and lower side wall 14 of the starting material 11 is made up of opposite inner layers 13a,14a connected to each other by means of loops 12 created by letting the thread 12 traverse first one inner layer 13a and then the second inner layer 14a and then letting two ends of the thread 12 be connected to each other. This can for example take place during weaving or during another suitable textile manufacturing method.
  • the circumferential wall 6 can be made of the same double-walled material as the starting materials 9;11 shown in figs. 2a and 2b, in which case the circumferential wall also must be inflated before use.
  • the circumferential wall can merely be made up of a single wall without threads.
  • the bouncy cushion can also be used for e.g. springboard in connection with artistic gymnastics, as trampoline, as gymnastic equipment for e.g. promoting motor behaviour and as air mattress for sleeping on.
  • the thickness, air pressure and number and distribution of flexible threads in the bouncy cushion is easily chosen in relation to the desired object so that the bouncy cushion meet current safety requirements.
