A device for training and rehabilitation
Field of the invention
The invention relates to the field of sports and sport
rehabilitation, in particular to a device for training and
rehabilitation, comprising a ball, connected in a dismantable
way with at least one rod shaft.
Prior art
Balls are employed, apart from their proper use in ball games
(either on sport, or recreation basis), also as training tools
and rehabilitation tools.
For example, the document CZ 21390 U1 is known from the state
of the art which discloses a pendulous ball for training
volleyball technique. The ball is positioned on a supporting
arm placed on a telescopic rod. The ball is attached to the
arm by means of a magnetic field created between an iron strip
glued to the ball by means of a rubber ring and a neodymium
magnet placed on the end of the supporting arm. The supporting
arm is formed by a rod provided with a spring to enable the
side movement of the rod with the ball.
The disadvantage of this solution is that its use is limited
to training in gymnasiums and it may be used only for a
particular training of a volleyball stroke (spike). A ball
modified in this way cannot be used for regular play due to
the imminent injury caused by the iron strip placed in the
ball. A ball modified in this way cannot be used for any other
sports or for rehabilitation purposes.
The aim of the present invention is to create a universal
device which can serve for training of different ball games,

WO 2017/036435 PCT/CZ2016/050032
as well as a rehabilitation device, whereas the ball can be
used also for regular play.
Summary of the invention
This aim is solved by the device for training and
rehabilitation according to the present invention. The device
comprises a ball, connected in a dismantable way with at least
one rod shaft, whereas the rod shaft is at one of its ends
provided with an anchoring means for anchoring to the ball.
The ball is to be understood as any ball or small ball, of any
shape, designed for any sport, optionally a ball without a
designation for a particular sport. Balls can be of any
material, for example rubber, plastic, gum elastic, leather,
created from a composite material, from a rubberized layered
material, foam, soft foam, etc.
Balls may be either single-shell balls or double-shell balls.
Single-shell balls have only a single shell. In case of
double-shell balls, the outer shell is the casing or cover of
the ball and the second shell is the bladder of the ball.
The rod shaft may be from a hard material, such as for example
hard plastic, wood, metal, or from a flexible material, such
as for example rubber, silicon, gum elastic, braided multi-
layered rubber, soft foam, foam, or made from composite
materials. The rod shaft may either have a fixed length, or an
adjustable length, for example in the form of a telescopic
rod. The rod shaft may have any cross-section, for example
circular, semi-circular, square or hexagonal. The rod shaft
may be easily attached to the ball and it can in turn be
easily removed from the ball, whereas the ball without the
shaft may be used for regular play.

The anchoring means may be made of different materials,
usually from flexible materials, such as plastic, gum elastic,
silicone or composite materials, whereas preferably are used
such materials which will minimise the abrasion at the place
of the anchoring slot in the casing of the ball, and will at
the same time prevent injury in case of the contact of the
person using the device with the ball in the area of the
anchoring slot. The anchoring means may be made by many
different methods. The important thing is that the means
secures the connection between the ball and the rod shaft so
that the ball is not loosened unintentionally during training
or rehabilitation.
The anchoring means may be positioned so that it fits closely
to the valve of the ball, but it may be also in the opposite
position to the valve of the ball, or optionally in any other
position to the valve of the ball.
In case of double-shell balls, the anchoring means is usually
placed outside of the valve of the ball.
In one embodiment of the invention, an anchoring slot is
formed in the casing of the ball (outside of the valve of the
ball), where the anchoring means fits. The anchoring slot is
made in the outer casing of the ball as a hole in the casing
of the ball, so that the bladder of the ball is not affected.
The shape and diameter of the slot is so that it enables the
fitting and holding of the anchoring means in the casing of
the ball and prevents spontaneous release of the anchoring
means during training or rehabilitation. From the perspective
of using the ball for regular play, it is convenient if the
slot is of the smallest possible diameter.
In one embodiment of the invention, the anchoring means is a
slightly convex body of a circular shape which is inserted
into the anchoring slot. The anchoring means may be provided,

WO 2017/036435 PCT/CZ2016/050032
for the purposes of connecting with the rod shaft and fixing
the means in the anchoring slot, with a connecting material,
such as a bolt (with any shape of its head) with a coil,
either inner coil or outer coil, and may be further provided
with layering, antiskid means or a groove on its perimeter.
In another embodiment of the invention, the anchoring means is
an outer convex cover of a circular shape which is put on the
outer side of the ball and which is further provided with an
insert which fits into the anchoring slot.
The insert can be, for example, in the shape of a cylinder, or
in the shape of a truncated cone. The insert can be made of
any flexible material, such as gum elastic, silicone etc. It
may be in the form of a cast, when the insert is made in one
piece, or it can be assembled from several pieces using
standard connecting means. The anchoring means is usually
inserted into the ball when the pressure in the ball is
deflated, when the ball is softer and the bladder of the ball
will accommodate to the shape of the insert. After re-
inflating the ball, the insert easily holds inside the
anchoring slot. The cover may be provided with other means for
fixing the anchoring means, for example by layering, antiskid
bumps, etc. The cover can be also provided with a coil. The
insert is connected with the cover by suitable means, such as
bolts, flexible washers, strengthening rings etc.
In another embodiment of the invention, related to single-
shell balls, the anchoring means is typically placed so that
it is attached to the valve of the ball. The valve and the
anchoring means may be connected by regular connecting means.
The valve may be used for re-inflating the ball, for example
after unscrewing the means. The valve and the anchoring means
can be also connected in a permanent manner, for example by
gluing.

The connection between the rod shaft and the anchoring means
may be either firm or in a dismantable way. If it is
dismantable, the dismantability of the connection is usually
ensured by a coil, for example using threaded rods with inner
or outer coil.
In order to increase safety and decrease the risk of injury,
balls may be provided with a safety cord or string which will
ensure that in case of an unexpected tearing, damaging or
removing of the ball, the ball will keep hanging on the rod
shaft.
Preferably, the rod shaft is at its second end provided with a
gripping means. The gripping means may be for example a ring
(a hard plastic, or flexible gum elastic), grip in the form of
the letter T, handle, handgrip, hilt or strap. The gripping
means may be attached to the rod shaft by a permanent
connection, or may be attachable using suitable means for
attaching the gripping means to the rod shaft (for example by
screwing). The gripping means may be made from any material,
for example hard, such as plastic, aluminium, titanium,
carbon, steel, or flexible, such as silicone, gum elastic or
composite materials.
Preferably, the ball is connected in a dismantable way with
more rod shafts, such as two, four, six or eight. In such a
case, each rod shaft is provided on one of its ends with an
anchoring means, and for each rod shaft, a corresponding
anchoring slot is made in the casing of the ball, while the
means of the rod shaft fits into the slot.
Preferably, the rod shaft is provided around its perimeter
with a protecting means, the aim of which is to prevent injury
of a user in contact with the rod shaft. The protecting means
may be in the form of a softened material glued in a permanent
manner to the rod shaft. In this case, the gripping means is
SUBSTFUTESHEETS(RULEM
CA 02995508 2018-02-13
WO 2017/036435 PCT/CZ2016/050032
typically attached to the protecting means. The protecting
means may also be in the form of a sleeve from a softened
material which is pushed onto or spread to the rod shaft. In
this case, the protecting means is fixed to the rod shaft by
means of suitable holds.
Preferably, the rod shaft has an adjustable length. This can
be achieved for example by using a telescopic rod, provided
for example with holes for adjusting the length.
When connecting the individual pieces, any available
connecting and auxiliary material may be used, for example
bolts (with circular, semi-circular, or conical head), safety
bolts, pegs, pivots, threaded rods with inner and outer coils,
casings, washers, springs, flexible washers, nuts, poles,
cords, strings, etc.
