Abstract

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, the rod shaft being provided at one of its ends with anchoring means.

Description

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, SUBSTFUTESHEETS(RULEM

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,

3 SUBSTFUTESHEETS(RULEM

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.

4 SUBSTFUTESHEETS(RULEM

5 PCT/CZ2016/050032 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

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.
