Field of the Invention
[0001] The present invention concerns a transition device with joining means for use in
joining athletic appliances, an athletic appliance including at least one transition
device, and a method for using a transition device.
Background of the Invention
[0002] In connection with performing jumping, trampoline or tumbling gymnastics, it is common
to use various forms of floor pads/floor mats/landing mats, including air-filled products.
[0003] Through the years this type of products has found wide application in the world of
gymnastics and is used in connection with a great number of gymnastics. The products
in question are used as individual products or appliances, however, it is very common
to use several products in conjunction, why these products are typically equipped
with joining means in the form of strips of Velcro tapes sewn or glued thereon. By
joining such products with Velcro tapes, ample and secure joining is achieved which
is easily separated and jointed according to need. Examples of products that may be
joined with floor pads/floor mats/landing mats can be wedge mats, somersault vaulting
boxes, roll vaulting boxes, foam vaulting boxes, and other types of appliances.
[0004] On products as mentioned above, there are thus arranged strips of Velcro tape along
the edges such that these strips can be brought into engagement and thereby secure
respective appliances to each other.
[0005] The disadvantage of this kind of joining is that the joining means can be pulled
or torn apart when a gymnast e.g. lands on one appliance close to the joining means.
[0006] It is also known to use a transition device for filling the gap between a first appliance
and a second appliance, where the transition device and the appliances are all provided
with joining means, and where the transition device is joined with the first appliance
and the second appliance, respectively.
[0007] The disadvantage of this kind of joining is also that the joining means can be pulled
or torn apart when a gymnast e.g. lands on one appliance close to the joining means.
[0008] EP 2786786 A1 discloses e.g. a gymnastic appliance that is built up of a first appliance and a
second appliance, where both appliances have a top side, a bottom side and edge sides,
and where between the appliances there is arranged a transition device, however a
transition device that cannot be stretched. The two appliances and the transition
device are provided with joining means constituted by Velcro tapes, and therefore
it is the Velcro tapes that are subjected to the tensile load when gymnasts e.g. land
on the top sides of the appliances.
Object of the Invention
[0009] It is the object of the invention to indicate an improved solution for joining athletic
appliances, where a transition device can be joined to e.g. a first appliance and
a second appliance, but where the transition device includes at least one extension
spring member. The joining means are thereby not to absorb the load, and therefore
the joining means cannot be pulled or torn from each other when a gymnast, for example,
lands on an appliance close to the joining means, as the extension spring member will
yield. Therefore, the important issue is the presence of an extension spring member
since the extending properties are crucial for relieving the load to which the joining
means are subjected.
[0010] A further object of the invention is also that the joining means on the individual
athletic appliances are not loaded and worn to such a degree that it results in a
need for replacing the joining means due to inferior attaching capability.
Description of the Invention
[0011] According to a first aspect of the invention, the above indicated object is achieved
by a transition device as described by introduction and as described in the preamble
of claim 1, namely a transition device with joining means for use in joining athletic
appliances, the transition device at least including a length and a longitudinal direction,
an extension spring member and a joining part with joining means, the joining part
including at least two flaps, each flap including at least a first side, a second
side, a first edge and a second edge, where at least the first edge of each flap is
connected with the extension spring member and where at least the first side or second
side of each flap includes joining means.
[0012] In a preferred embodiment, the extension spring member can perform a reversible deformation
where the extension spring member can be extended as well as being capable of returning
to its original shape. The focus is therefore on the extending function.
[0013] This enables joining at least two athletic appliances provided with joining means
to each other and at the same time avoid that the joining means are pulled or torn
apart when a gymnast e.g. lands on an appliance close to the joining means. This is
avoided in that the extension spring member of the transition device yields, preferably
extending between 0 and 10 cm, however preferably between 3 and 6 cm, and such that
the load is not only absorbed by the joining means.
[0014] In a preferred embodiment, the joining part includes two flaps disposed substantially
in the same plane at each their side of the extension spring member. It is hereby
possible that both flaps can be connected to the top side of an athletic appliance.
[0015] In another preferred embodiment, the joining part includes two flaps disposed substantially
at right angles to each other. One flap may hereby be connected to the top side of
an athletic appliance, whereas the second flap can be connected to the edge of an
athletic appliance.
[0016] In a third embodiment, the joining part includes two flaps, each capable of being
connected to the top side of an athletic appliance and at the same time to the bottom
side of yet an athletic appliance, provided that the flaps have joining means at both
sides.
[0017] In a fourth preferred embodiment, the joining part includes three flaps of which
two flaps are disposed substantially in the same plane whereas the third flap is disposed
substantially at right angles to the two other flaps. The two flaps may hereby both
be connected to the top side of an athletic appliance, whereas the third flap can
be connected to the edge of the at least one athletic appliance. The two flaps located
in the same plane can be connected at the same time to the bottom side of yet an athletic
appliance, provided that the flaps have joining means at both sides.
[0018] In a fifth preferred embodiment, the joining part includes four flaps of which the
first two flaps are disposed substantially in the same plane, wherein the two flaps
each can be connected to the top side of an athletic appliance. The last two flaps
are also disposed substantially in the same plane, but in a plane in parallel with
the two first flaps. The remaining flaps can also be connected to the top side of
an athletic appliance, that e.g. is in the form of thin mats placed upon mattresses.
[0019] The length of a transition device may vary, but in a preferred embodiment, the length
of a transition device fits the width of a common landing mat or floor mat, which
is 2 metres. For example, two transition devices, each being two metres, can be laid
in continuation of each other for use e.g. in assemblies that are 4 metres long.
[0020] Some athletic appliances have joining means along one side, along two sides or along
several sides, faces and/or edges, and the invention indicated above is very attractive
in connection with joining a large number of different or uniform appliances irrespective
of the location at which the respective joining means are arranged. These may be athletic
appliances that are foam-filled and/or air-filled, made of wood, plastic or other
suitable materials, including traditional or more modem appliances, such as e.g. parkour
appliances, that may be joined according to the invention.
[0021] The joining means are in a preferred embodiment Velcro tapes, but may e.g. be buttons,
press studs, zippers, hooks or clasps.
[0022] The extension spring member may further include cover means for covering and possibly
shielding the extension spring member partly or entirely from the surroundings. It
is a condition that the cover means are flexible and therefore able to adapt to the
movements of the extension spring member.
[0023] In a preferred embodiment, the cover means includes a pocket in which the extension
spring member is provided and where the extension spring member therefore is well
shielded from the surroundings and well protected against wear, among others.
[0024] Where the cover means include a pocket completely enclosing the extension spring
member, the joining means are consequently connected to the cover means and thus indirectly
to the extension spring member.
[0025] In a second preferred embodiment where the two flaps of the joining parts are disposed
substantially in the same plane, it is only the part of the cover means facing upwards
and thus away from the joined gymnastic appliances that is visible. Thereby it is
possible to have cover means only at the top side of the transition device.
[0026] In a second aspect, the present invention also concerns a transition device wherein
the extension spring member further includes at least one inflatable chamber and at
least one valve.
[0027] By inflatable is meant here the option of using and pumping a desired gas or a gas
mixture, such as e.g. and preferably air, into the at least one inflatable chamber.
By an inflatable chamber is meant a closed compartment to which air by means of a
valve can be supplied or removed.
[0028] Alternatively, it may be a multi-chamber system wherein the chambers are interconnected,
and where one valve therefore is sufficient.
[0029] In a further alternative embodiment, there may be several separate chambers above
each other, side-by-side, or externally of each other. It may thus be a system with
several valves.
[0030] Each valve may also have an overpressure device such that the pressure is regulated,
thereby ensuring that the extension spring member will not rupture. An overpressure
device can thus be an overpressure valve regulating the pressure.
[0031] In an third aspect, the present invention also concerns a transition device wherein
the extension spring member includes at least one foam element.
[0032] When a load is applied to an athletic appliance this will further enable changing
the shape of the foam element without breaking the foam element and without the joining
means being pulled or torn apart.
[0033] In a preferred embodiment, the foam element is a foam tube. It is therefore expedient
to use cover means in the form of a 360° pocket, preferably circular, whereby it is
easy and simple to place and possibly replace the foam tubes. The foam tubes may have
different lengths that may be assembled by means of a joining member, which in a preferred
embodiment is a tube piece or a rod on which the foam tubes can be pushed in over
from both ends of the tube piece or rod.
[0034] In a second preferred embodiment, the foam element is a foam stick, and in further
embodiments the foam element is designed specifically to fit the gaps between the
desired athletic appliances, with a cross-sectional shape that is e.g. triangular,
convex or concave.
[0035] By the embodiments where the extension spring member includes a pocket, a foam element
can readily be replaced, and thereby it is also possible to replace e.g. a foam element
with one elastic property with a foam element with another elastic property. In order
to prevent the foam element from falling/moving out of the pocket, in a preferred
embodiment there is an opening/closable end in the extension spring member of the
transition device.
[0036] In a preferred embodiment, the foam element is made of polyurethane.
[0037] It will thus also be possible to combine a foam element with an inflatable chamber.
[0038] In a fourth aspect, the present invention also concerns a transition device wherein
the extension spring member includes at least one rubber band.
[0039] When a load is applied on an athletic appliance, this will enable changing the shape
of the rubber band such that the joining means are not pulled or torn apart.
[0040] In a preferred embodiment, the rubber band is directly connected with the joining
part, and the cover means may in an embodiment suffice with covering one side of the
rubber band, i.e. preferably the parts of the rubber band and the transition device
that are visible after joining a number of athletic appliances.
[0041] By the embodiments where the extension spring member includes a pocket, inside the
pocket there is at least one elastic or rubber band preferably disposed in the same
plane as the one in which the joining part is placed externally of the pocket. Where
the at least two flaps of the joining part are not disposed in the same plane, the
at least one rubber band or elastic is disposed in continuation of the joining part
which is provided externally of the pocket.
[0042] In a fifth aspect, the present invention also concerns a transition device wherein
the extension spring member includes at least one spring.
[0043] When an athletic appliance is loaded, this will enable pulling the spring such that
the spring becomes longer and such that the joining means are not pulled or torn apart.
[0044] In a preferred embodiment, the spring is directly connected with the joining part,
and the cover means may in an embodiment suffice with covering the parts of the spring
and of the transition device that are visible after joining with a number of athletic
appliances.
[0045] By the embodiments where the extension spring member includes a pocket, inside the
pocket there is provided at least one spring preferably disposed in the same plane
in which the joining part is placed externally of the pocket.
[0046] In a preferred embodiment, several springs are mounted transversely to the longitudinal
direction of the transition device, where the springs preferably are identical and
with the same elastic modulus, though the springs may be with different elastic modulus
as well.
[0047] In a further preferred embodiment, the springs can be disposed mutually offset at
different planes or at different mutual angles, but where the springs are capable
of absorbing the load on the athletic appliances.
[0048] In a sixth aspect, the present invention also concerns a transition device wherein
the first and second sides of the at least one flap of the joining part include joining
means, respectively.
[0049] This will enable making the transition device more flexible such that the at least
one flap can be connected to more than one athletic appliance and can be connected
to a mat and a mattress lying upon each other, for example.
[0050] In a preferred embodiment, the first side and second side of each flap of the joining
part include joining means. Each of the flaps can hereby be connected to the top side
or bottom side of at least one athletic appliance.
[0051] In a second preferred embodiment, where the first side and second side of each flap
both include joining means, the flaps can be connected to the top side of an athletic
appliance and to the bottom side of another athletic appliance, respectively, if located
in the same plane.
[0052] In a seventh aspect, the present invention also concerns a transition device where
the joining means on each flap either includes Velcro tape only with hooks or only
with loops.
[0053] This may ensure that the Velcro tape cannot be turned upside down, and additionally
there may be some production advantages associated with such a solution as not all
types of Velcro tapes are equally easy to handle in the different situations.
[0054] In an eighth aspect, the present invention also concerns a transition device where
joining means on each side of a flap both includes Velcro tape with hooks and with
loops.
[0055] This enables coupling two appliances together without regard to respective parts
having one or the other type of Velcro tape as there are no longer specific male-female
parts, but so that in a preferred embodiment universal Velcro tapes can be coupled
with corresponding Velcro tapes.
[0056] In an alternative embodiment, the joining means include Velcro tape with hooks as
well as with loops on each flap, where the hooks e.g. are in one row or a section/area
by itself, whereas the loops are in another row or in another section/area by itself.
[0057] In a ninth aspect, the present invention also concerns an athletic appliance including
at least one transition device according to the invention, the athletic appliance
being of the type typically used in connection with performing jumping, trampoline
or tumbling, wherein the athletic appliance includes at least a first appliance and
a second appliance, wherein at least one of the appliances, e.g. an elastic pad/element,
includes a top side, a bottom side and a number of edge sides, and further including
joining means at or along at least part of the top side, bottom side and/or edge sides
of the appliance, and wherein the first and the second appliance via the joining means
are adapted for mutual joining by transition devices, wherein this joining is effected
by complementary joining means arranged on respective appliances and transition devices
that together constitute a gymnastic appliance.
[0058] This enables joining athletic appliances by a transition device where the transition
device includes at least one extension spring member. The joining means cannot thereby
be pulled or torn from each other when a gymnast, for example, lands on an appliance
close to the joining means as the extension spring member will yield.
[0059] In a tenth aspect, the present invention also concerns a method for using a transition
device according to the invention for joining athletic appliances of the type typically
used in connection with performing jumping, trampoline or tumbling, wherein at least
one athletic appliance, e.g. an elastic pad/element, includes a top side, a bottom
side and a number of edge sides, and further including joining means at or along at
least part of the top side, bottom side and/or edge sides of the appliance, and wherein
the first and the second appliance via the joining means are adapted for mutual joining
by transition devices, wherein this joining is effected by complementary joining means
arranged on respective appliances and transition devices that together constitute
an athletic appliance, and wherein the method includes at least the following steps:
- providing a first athletic appliance with joining means;
- providing a second athletic appliance with joining means;
- providing a transition device with joining means;
- providing and mounting at least one transition device with joining means including
Velcro tape between the athletic appliances.
