Suspension for Application to Sports Devices
Abstract
The invention relates to a spray can (20) for applying adhesive
(3) and anti-slip particles (2) to sports devices (10). The spray
can (20) comprises an at least partially pressurized body (4) with
a spray nozzle (5), which is filled at least partially with a
propellant. In addition to the propellant, at least one adhesive
(3) and anti-slip particles (2) are contained in the spray can
(20). In order to increase the static friction on sports devices
(1), possibly also for just a short time, anti-slip particles (2)
and adhesive (3) are applied with the aid of the spray can (20). In
this way, the static friction on holding elements, in particular of
sports devices (10), can be increased very quickly. The spray can
(20) can be designed in one part or in two parts. In a one-part
design, the anti-slip particles are added directly to the adhesive.
In a two-part design, the anti-slip particles are stored in a
second chamber of the spray can (20). In the two-part design,
anti-slip particles can be added to the adhesive.

Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application is the U.S. national stage of International
Application No. PCT/DE2011/001973, filed on Nov. 11, 2011, and
claims the benefit thereof. The international application claims
the benefits of German Application No. 102010051090.4 filed on Nov.
12, 2010; all applications are incorporated by reference herein in
their entirety.
BACKGROUND
[0002] The invention relates to a spray can comprising an at least
partially pressurized body with a spray nozzle that is at least
partially filled with a propellant.
[0003] It is very important for the user to get a firm hold on the
sports device when using sports devices such as skateboards,
scooters, boots, motor scooters or the like. Strips with abrasive
or anti-slip particles to be affixed in the form of adhesive
elements are known in the prior art to increase the static friction
on the standing and holding areas.
[0004] Adhesive strips of that type are available in standard
dimensions and have to be applied to the respective sports device
in a complicated way and cut to size. A further drawback to these
adhesive strips arises because of the fact that a new strip has to
be applied as soon as the anti-slip particles are worn away. The
old, worn-away strip has to be removed from the sports device in
the process. The sports device can occasionally be damaged when the
adhesive strip is removed. Furthermore, it turns out to be
extremely difficult to remove the entire adhesive strip with all
residuals so that a new adhesive strip can be cleanly applied. The
replacement of an adhesive strip of that type therefore takes a
long time and can also only be done with a great deal of effort.
Specifically in the case of sports events, this amount of time is
not available to a sufficient extent.
[0005] Moreover, a combination of a separate adhesive and ground
glass for application to sports devices can be found in the prior
art. This application serves to provide a point-by-point
improvement of worn-away areas of the adhesive element of a sports
device. The adhesive is applied to the areas to be repair, and the
ground glass is sprinkled on. The adhesive that is used has a
drying time of more than 40 minutes. The ground glass that is used
has an average size of 40 .mu.m. A major drawback of this
application is that it cannot be applied over large areas of the
sports device.
[0006] The ground glass is not suitable for a large-surface
application. To apply this over a large area, a very large quantity
of material has to be applied to the sports device due to the small
grain size. The large stock of ground glass has to be kept
available. It is necessary to carry out the repair work in a
workshop for this. This is extremely restrictive, because a mobile
application is not possible as a result of that.
[0007] Furthermore, the long drying time of the adhesive is
especially disadvantageous for quick repairs of the adhesive
element. Making the sports device available and ready for use again
in a very short period of time is especially important in the area
of sports. As an example, the adhesive element should be touched up
or replaced during short rest periods. A setting time of more than
40 minutes is therefore not suitable for use with sports
devices.
DETAILED DESCRIPTION
[0008] The object of the invention is to therefore provide an agent
that can be simply and quickly applied, that increases the static
friction on sports devices and that therefore improves the hold of
the user.
[0009] The problem as per the invention is solved by including at
least an adhesive and anti-slip particles in addition to the
propellant. Further advantageous design forms of the invention
follow from the sub-claims.
[0010] The special advantage of a spray can in contrast to the
prior art is that it can always be carried around everywhere by the
user. A small embodiment can be carried along in a jacket or pants
pocket, for instance. Moreover, it is also conceivable to design a
spray can in terms of its size, shape and weight so that it can be
carried along in a sports bag, for example.
[0011] The pressure in the spray can and the propellant in the can
make simple spraying of the adhesive possible with the aid of a
spray nozzle. The adhesive can therefore be simply applied to an
adhesive element, for instance that of a sports device. The user
has to only actuate the spray nozzle for that and evenly apply the
adhesive to the adhesive element of the sports device at a
specified distance form the spray nozzle.
[0012] A complicated process of cutting adhesive strips to the size
of the surface of the sports device to be treated is not necessary.
The spray can be used for a surface of any size and shape. Even
hard-to-reach areas of sports devices are consequently accessible,
for instance round areas of handles.
[0013] The anti-slip particles are also added to the adhesive in an
advantageous design form; they have an average size of 50 to 1,000
.mu.m, preferably 100 to 500 .mu.m, and especially preferably 50 to
250 .mu.m. When the anti-slip particles are added to the adhesive,
the static friction on the holding element of sports devices, for
instance, is especially increased with the application of the
adhesive. The static friction can hereby be applied to anti-slip
surfaces that already exist.
[0014] The average size of the anti-slip particles that are used
can be adapted to the application in the process. As an example, a
larger grain size with an average size of up to 1,000 .mu.m is
advantageous for sports devices for which the adhesive element is
intended to be used with shoes. That is the case for skateboards
that the user stands on with his shoes to carry out tasks and
exercises, for instance. A large average size of the anti-slip
particles is advantageous in connection with this, because the
contact surface and therefore the static friction are substantially
increased as a result of that.
[0015] A smaller average size of the anti-slip particles is
preferred with other application variants in which the adhesive
element makes contact with the skin of the user. That is the case,
as an example, for surfboards for which the user stands with bare
feet on the sports device or lies on it wearing only swimming
trunks. A large grain size of the anti-slip particles will be
perceived as unpleasant by the user in connection with this. A
smaller grain size of 100 to 500 .mu.m reduces the contact surface
vis-a-vis the above-mentioned large grain size and permits more
pleasant handling of the sports device. That is necessary, among
other reasons, to avoid injury by the adhesive element.
[0016] High levels of holding force can be built up, because the
contact surface and therefore the static friction are large in the
case of a large average size of the anti-slip particles. If the
force with which the user is at risk of slipping off exceeds the
opposing force of the static friction, unpleasant injuries such as
abrasions could come about when the user slips off the sports
device.
[0017] Sports devices that come into contact with especially
sensitive areas of the skin can be provided with an even finer
grain size of the anti-slip particles, for instance with an average
size of 150 to 250 .mu.m. That is especially the case for
surfboards that are used in a prone position by the user.
Furthermore, it is conceivable to also use this for handles of
bicycles, tennis rackets or the like.
[0018] In a further advantageous design form, the body of the spray
can comprises two chambers; one chamber is provided to hold at
least propellant and adhesive, and the second chamber is provided
to hold anti-slip particles with an average size of 200 to 2,000
.mu.m, preferably 500 to 1,250 .mu.m. The fact that especially
large average sizes of the anti-slip particles are used is
especially advantageous in this embodiment. The two chambers of the
body can be designed as one piece, as an example. An embodiment
with a double base particularly suggests itself for this.
[0019] A two-piece design with chambers that can be separated from
one another is likewise conceivable. The upper chamber can be
filled with the adhesive and the propellant and provided with a
spray nozzle here. The lower chamber is filled with anti-slip
particles. The lower chamber is provided with at least a closable
opening in this embodiment. The anti-slip particles can escape
through this opening.
[0020] The use of the spray can then provides for a prior spraying
of the adhesive onto the adhesive element with the aid of the
propellant and a subsequent application of the anti-slip particles.
The anti-slip particles that are included separately from the
adhesive in the spray can could have an especially coarse grain
size here. Particles with an average size of up to 2,000 .mu.m can
be included in connection with this. The opening in the second
chamber can be towards the side or towards the bottom, for
instance. The anti-slip particles can be simply applied to the
sports device with the aid of the opening.
[0021] The opening is adapted to the size of the anti-slip
particles in the process. The opening can be provided with a screen
in connection with this that at least partially closes the opening
with different mesh sizes. A slider or twisting closure can be
provided here. Different mesh sizes of the screen are selected by
sliding or twisting the closure to apply anti-slip particles of
different sizes. That is particularly advantageous when anti-slip
particles with different sizes are stored in the second
chamber.
[0022] The spray can be used for a multitude of different
applications because of the use of screens with different mesh
sizes. This extends from the application to skateboards with an
especially coarse grain size to the application to handles with an
especially find grain size. In particular, anti-slip particles with
an average size of up to 2,000 .mu.m can be used in this
embodiment. The contact surface and therefore the static friction
are increased even further because of the use of anti-slip
particles of that size.
[0023] It is also possible in this embodiment to add anti-slip
particles to the adhesive in addition to the anti-slip particles in
the second chamber.
[0024] In an especially advantageous design form, anti-slip
particles with an average size of 50 to 1,000 .mu.m are added to
the adhesive in the first chamber and anti-slip particles with an
average size of 200 to 2,000 .mu.m are provided in the second
chamber of the body.
[0025] Enriching the anti-slip particles with a proportion by
weight of 10 to 80% vis-a-vis the proportion of adhesive, 30 to 60%
is especially preferred, is particularly advantageous. This range
results for the use of different particles. A proportion by weight
of the particles of 10% can already be adequate when certain
particles and adhesives are used. A proportion of anti-slip
particles of up to 80% can be necessary for other mixtures. This is
particularly the case when the spray can has to be optimized for
certain applications. For instance, also increasing the static
friction for moist to wet conditions. The range from 30 to 60% by
weight has an especially preferential suitability, because this
range provides an optimal result for the majority of anti-slip
particles and adhesive mixtures.
[0026] The increase in static friction is enabled by the use of
anti-slip particles, especially if they are made up of stone
chippings, garnet, aluminum oxide, silicon carbide, aluminum-zinc
oxide, chromic oxide, ceramic aluminum oxide, silicon dioxide or
rubber particles, either as individual components or a mixture of
these components. In particular, a mixture of two or more
components of the particles listed above is especially suitable for
increasing the static friction.
[0027] The adhesive is a physically setting, chemically hardening
adhesive or a pressure-sensitive adhesive depending on the
requirements on the spray can. Furthermore, paint can be mixed in
with the adhesive. The desire to be different is especially great
in youth and leisure sports. The paint that is mixed in permits the
user to also individually design the surface of the sports
devices.
[0028] The adhesive has a hardening time of 3 to 5 minutes,
preferably less than 2 minutes, in an advantageous design form.
Only a short drying time of that type makes it possible for the
user to quickly use the spray can without major restrictions, for
instance during breaks in the competition, to increase the static
friction and the hold.
[0029] The suspension has the major advantage vis-a-vis the prior
art that it is easy to apply. The suspension can either be sprayed
on, painted on or dabbed on. A complicated process of cutting it to
the size of the surface of the sports device to be treated is not
required, in contrast to the prior art. The suspension can be
applied to a surface of any size and shape and can therefore even
increase the static friction and therefore the hold in
hard-to-reach areas of the sports device. The suspension can
likewise be applied to the existing anti-slip surfaces in an
advantageous way; their static friction can be quickly applied
without taking a great deal of time, particularly during sports
competitions, and the grip is consequently substantially increased
because of this. This type of application can be repeated several
times, one after the other, in connection with this.
[0030] To make the application easier, the suspension is provided
in a spray can that ensures simple handling; the suspension can be
applied especially quickly because of that. The suspension can be
carried along by the user and quickly sprayed on between uses, if
necessary, to also quickly increase the static friction.
[0031] In particular, the suspension can be used in competitions to
quickly increase the static friction between two runs or
presentations, for example, and to therefore achieve optimal
conditions for the user. Furthermore, the suspension offers the
advantage that it does not have to be removed again from the sports
device in a time-consuming way after it wears away, in contrast to
the adhesive strips from the prior art; instead, the suspension can
be simply and quickly applied to the sports device once again.
[0032] The static friction of the surface of the sports device and
therefore the user's hold are improved by the use of anti-slip
particles with an average size of 50 to 2,000 .mu.m. The choice of
the average size of the anti-slip particles depends on the
circumstances, for instance large particles are required for a
moist to wet application environment and small particles are
sufficient when there is skin contact or indirect contact, for
example shoes.
[0033] The static friction can already be increased to an adequate
degree with an average particle size of 50 .mu.m with certain
mixtures of particles and adhesives. An average particle size of
2,000 .mu.m could be required for other applications, especially
for wet environments. An average particle size of 150 to 250 .mu.m
or of 500 to 1,250 .mu.m is sufficient to appropriately increase
the static friction for most application areas and
particle-adhesive mixtures.
[0034] To apply the suspension in an especially easy way, it can be
sprayed on, painted on or dabbed on. The special advantage
vis-a-vis the prior art is the simple and quick application that
permits the suspension to be newly applied in a very short period
of time, for instance when there are breaks in the competition. Use
of the sports device is possible after a short period of time in
combination with a quickly setting glue.
[0035] The suspension is especially intended to be used for
application to sports devices, such as skateboards and surfboards,
to increase the static friction. Improving the contact between the
user and the sports device is very important with regard to sports
devices. That is especially the case when the user's hold on the
sports device is only ensured with the static friction, for
instance in the case of skateboards and surfboards, to carry out
the desired figures and exercises.
[0036] A drying time of three to five minutes, preferably less than
two minutes, ensures that the suspension can be quickly used. This
short drying time makes it possible for the user to quickly apply
the suspension without major restrictions, for instance during
breaks in the competition, to increase the static friction and the
hold.
[0037] Furthermore, paint can be mixed in with the adhesive. The
desire to be different is especially great in youth and leisure
sports. The paint that is mixed in permits the user to also
individually design the surface of the sports devices.
[0038] The adhesive is a physically setting, chemically hardening
adhesive or a pressure-sensitive adhesive depending on the
requirements on the suspension. A physically setting or chemically
hardening adhesive is outstandingly suitable for painting and
dabbing applications, for example. A pressure-sensitive adhesive is
especially suitable for sprayable applications.
[0039] Furthermore, a spray can is particularly suitable for
applying the suspension to sports devices in a special way; the
spray can comprises a pressurized body with a spray nozzle, which
is at least partially filled with a propellant. An adhesive and the
anti-slip particles are contained in the spray can for this, in
addition to the propellant. The spray can allows the user to apply
the suspension in an especially simple fashion, because the spray
can is carried along by the user and can be used at any time.
BRIEF DESCRIPTION OF THE DRAWINGS
[0040] The invention will be explained once again below with the
aid of the figures.
[0041] FIG. 1 shows a sports device with applied suspension in an
oblique view,
[0042] FIG. 2 shows a spray can with suspension being discharged
and
[0043] FIG. 3 shows a spray can comprising two chambers.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0044] A sports device 10 is shown in an oblique view in FIG. 1. A
suspension 1 with anti-slip particles 2 and an enriched adhesive 3
is applied to the surface of the sports device 10. The static
friction and therefore the hold of the user on the surface of the
sports device 10 are increased via the anti-slip particles 2. FIG.
2 shows a spray can 20 with a discharging suspension 1 with
anti-slip particles 2 and an enriched adhesive 3. The spray can 20
comprises a pressurized body 4 with a spray nozzle 5.
[0045] The spray can 20 is at least partially filled with a
propellant to spray the suspension 1. The spray can 20 allows the
suspension 1 to be applied to sports devices 10 in an especially
quick and simple way.
[0046] FIG. 3 shows a special embodiment of the spray can; the body
4 comprises a first chamber 22 and a second chamber 23. The first
chamber 22 holds the adhesive 3 in connection with this. It can be
discharged through a spray nozzle 5 with the aid of a propellant
contained in the first chamber 22 and the pressure built up in the
first chamber 22 and applied to a sports device 10. The second
chamber 23 holds anti-slip particles 2. The anti-slip particles 2
can be brought out through the opening that is provided with a
screen 24. The screen 24 also preferentially has a closure that is
not shown here. The anti-slip particles 2 can therefore be brought
out of the second chamber 23 with a simply shaking of the spray can
20. The embodiment of the spray can 20 shown here is especially
advantageous for using anti-slip particles with a coarse grain size
and an average size of 200 to 2,000 .mu.m, preferably 500 to 1,250
.mu.m. Anti-slip particles 2 that have an average grain size of 50
to 1,000 .mu.m, preferably 100 to 500 .mu.m, with a special
preference for 150 to 250 .mu.m, can also be added to the adhesive
3.
[0047] The anti-slip particles 2 are applied to a sports device 10
as follows. First off, the adhesive 3 that has already been
provided with anti-slip particles 2 under certain circumstances is
applied to the adhesive element of the sports device 10 with the
aid of the spray nozzle 5. If anti-slip particles with a coarse
grain size are to be used on the adhesive element, anti-slip
particles 2 can be applied from the second chamber 23 with the aid
of the screen 24 over the sports device 10 supplied with adhesive 3
with a simple shaking of the spray can 20. A spray can 20 in
accordance with this example is especially advantageous for
applications in which high static friction is required, for
instance for skateboards.
