METHOD OF MANUFACTURING A BALL WITH EMBEDDED MODULES
Document Type and Number:
WIPO Patent Application WO/2003/059727
Kind Code:
A2
Abstract:
Making of module ball refers to technology of production of PVC ball filled with compressed air, accommodated for installation of different modules, depending on the size of the ball ( light emitting, sound emitting ball, light emitting buoy and similar), as well as to procedures and technologies of installation of modules into the ball wall, so as to shape the bed in the interior of the ball, in which corresponding module is simply pressed in, while the ball retains all essential properties of the ball, without any disturbance of its shape, balance. This is achieved by installation-of the balancing mass opposite to the module, ensuring good sealing due to clamping joint between the module and the bed.

PATENT CLAIMS
1. Making of module ball refers to production technology of PVC ball, filled with compressed air and accommodated for installation of various modules depending on ball application: light emitting ball, sound emitting ball, hanging ball for exercise, light emitting buoy and similar, and module installation procedure into the ball wall determined by building of the module bed within the ball wall and subsequent stamping of the module into the bed. Opposite to bed balance mass is shaped, without disrupting essential ball properties, ensuring closing of the ball to any leakage and proper balance of the ball.
2. Making of module ball according to requirements specified under No. 1 has been characterized by the fact that there are tools for production of balls, which can be simply remodeled into tools for fabrication of module ball, so that the spherical tool chamber is provided with arbor for module bed formation.
3. Making of module ball according to requirement 2 has been characterized by manufacture of the arbor in the contact area with spherical tool chamber; its form continuously spreading and accommodating to radius having approximately 50% of arbor diameter. Depth and diameter of the arbor must correspond to size of the bed, so as to be able to fulfill requirements of high quality sealing and taking over of mechanical stresses on contact surfaces between the bed and module.
4. Making of module ball according to requirements specified under No. 3 are determined by the function of the arbor, and the need to shape around it during stage of pouring of the ball the module bed.
5. The process of pouring of the ball determines module ball manufacture according to requirement No. 5. Base material surrounds the arbor and the pipe on its surface, so that the arbor builds homogenous bed integrated into the wall, and the bed must be shaped in such a manner that after module installation and filling of the ball with compressed air in the field of the bed, the ball wall is shaped in the form of continuous and regular surface without discontinuities and disruption of the object basic geometry.
6. Making of module ball according to requirement No. 6 is determined that module is simply stamped into the bed.
7. Making of module ball according to requirement No. 7 is determined by the requirement that module shape must be simple and its dimensions must allow for simple stamping into the bed. After the installation of module into the bed, elastic clamping joint must be formed, ensuring sealing and preventing movement of the module in the bed, its falling out of the bed during static and dynamic stresses.
8. Making of module ball according to requirements No. 8 are determined by the need that module diameter must be greater than arbor diameter, and the recommended value of the module and arbor ratio must amount to 1,5, which ratio in some cases may differ.
9. Making of module ball according to requirement No. 9 is determined by the need of having balancing mass (pipe having same weight as module) resting opposite to bed, which surrounds the base material creating preconditions for good static and dynamics of the ball.
10. Making of module ball according to requirement No. 10 is determined by the fact that ball with installed module can be easily turned into buoy by installation of specially shaped module for light emitting buoys (with attached element for attachment of the string) same as with light emitting ball, or without it.
Description:
MAKING OF MODULE BALL 1. FIELD OF APPLICATION This invention refers to production process of PVC ball, filled with compressed air, and accommodated for installation of diverse modules, depending on different application purposes, such as light-emitting ball, sound emitting ball, light-emitting buoy (float) and similar, as well as on procedures and installation technologies, how to install module into the ball wall, which matter has been categorized according to international classification standard (MKP) as: 2. TECHNICAL PROBLEM Due to need of installation of diverse modules (light-emitting, sound-emitting modules, module having function of taking over of force-handle, and similar) into elastic walls of the ball filled with compressed air, there is a need for solution of these problems: sealing problem around place of installation of the module, disruption of the basic ball geometry, problems of esthetics, together with creation of conditions to ensure good mechanical properties of the joint between the ball wall and the module itself.

3. STATE OF TECHNIQUE There are no universal solutions how to install the module (light-emitting, sound-emitting, force transfer module and similar) in the ball walls itself.

There are design solutions for balls with modules placed in its interior. These solutions show deficiencies in the following: construction of complex tools for

pouring, complex production process (two component ball filled with foam having role of fixing the module, or ball filled with plastic material and similar), weight of the object itself and poor mechanical strength. Main insufficiencies of these solutions lie in the fact that they completely change ball properties, when compared with PVC balls filled with compressed air.

4. FUNDAMENTALS OF INNOVATION Primary goal is to define production process of manufacture of PVC ball, filled with compressed air and accommodated for installation of different modules, depending of the ball application: light emitting ball, sound emitting ball, light emitting buoy and similar-to define procedures and technologies for installation of modules into the ball wall so that modules are simply stamped into the wall, without affecting the vital ball properties, its balance and simultaneously ensuring tight close against entry of leakage.

Secondary goal is to define: universal procedures of ball preparation and universal module shapes, with the objective of production of multi-purpose products (i. e. light emitting, sound emitting, hanging ball for exercise, light emitting buoy (float), and similar.

Additional goals and advantages are partly shown in the description, which follows, and partly will be known through future various applications of the innovation.

Manufacturing procedures and methods of shaping the ball and module to be installed, as well as procedures and installation technologies into the wall can be summarized to following course of actions: manufacture and remodeling of the existing pouring tools, manufacture of beds on the ball wall for installation of

module, process of shaping of balancing mass in the ball interior opposite to module installation bed, manufacture of installation module, definition of methods and procedures for module installation, whereby pouring tools must be made so as to have arbor opposite to pumping valve, having purpose to shape module bed around it during pouring procedure. Module bed itself is installed in such a way that preliminary prepared arbor tool is provided with pipe made of the same material as the base material (material used for manufacture of the ball). During pouring process of the ball the base material drenches the arbor and the pipe on their surface, in such a way that homogenous mass of module bed is being built around the arbor integrated into the ball wall. The bed itself is shaped in such a way that after module installation and filling the ball with compressed air, surface of the ball wall is shaped in the area of module bed, taking the form of continuous and regular surface (without discontinuities and disruption of basic geometry of the object), whereby module must be dimensioned and shaped so as to install it simply by plugging it in into the bed.

After installation into the bed, tight joint is being formed having the purpose of sealing and producing sufficient forces to prevent movement or fall out of the module from the bed (module diameter is approximately 1,5 times of the arbor diameter), under static and dynamic loadings, whereby module must possess required mechanical strength. Opposite to such shaped module bed, pumping valve is provided with balancing mass (PVC pipe having the same weight as the module), which is poured into the base material.

6. DETAILED DESCRIPTION OF AT LEAST ONE METHOD OF REALIZATION OF THE INNOVATION Now we shall give more detailed instructions of presupposed realization of the innovation, giving examples for manufacture and shaping of the wall of light emitting ball and the installed module (which is illustrated in accompanying drawings).

Referring to Fig. 1 it can be seen that the pouring tool for light emitting ball consists of the housing in the shape of cylindrical chamber (Fig. 1, Position 1) and threaded arbor (Fig. 1, Pos. 2), which is installed into the wall of the existing pouring tool (for pouring of standard balls) or the new tool.

The arbor is manufactured so that its shape in the area of its contact with the cylindrical shaped tool chamber can continuously spread to the next corresponding radius having the value close to 50% of the arbor diameter (Fig.

1, Position 2).

Depth and diameter of the arbor must have such dimensions so as that the bed can take over all static and dynamic stresses on contact surfaces between bed and module (Fig. 1, Position 2 and Fig. 5). Its function is based on the requirement that during pouring procedure module installation bed can be shaped.

After arbor installation, the same procedure is applied regarding previously prepared pipe made of material with similar properties as the ball material, and having the same depth and length as the flat part of the arbor (Fig. 2, Pos. 3).

After starting of the process of ball pouring, base material drenches the arbor and the pipe on their surfaces, so as to create homogenous bed mass integrated into the ball wall (Fig. 3).

The bed is shaped so that after module installation and filling in of the ball with compressed air, the ball surface is shaped in the form of continuous and regular surface (without discontinuities or disruption of ball basic geometry)- Fig. 5. After finishing of the ball pouring process, shaping of the module installation bed (Fig. 3, Pos. 2) has been completed.

Module (Fig. 4) is installed in such prepared bed by simply stamping it into the bed.

In this case we deal with light emitting ball with installed light module.

Module has been shaped and dimensioned in such a way, that it can be inserted simply by stamping it into the bed (ingoing edge shown on Fig. 4, Detail"a").

After installation into the bed, elastic clamping joint is formed having the function of sealing and creating of sufficient force to prevent movement of the module in the bed or falling out under static and dynamic stresses.

Module diameter must be larger than the arbor diameter. Recommended value of ratio between module and arbor diameter is 1,5, which ratio might be in certain cases also different. Module must possess necessary mechanical properties. Opposite to such shaped bed, balancing mass Fig. 3, Position 3 and PVC pipe are being positioned, having same weight as module itself and drenching the base material during pouring procedure.

The same manufacturing procedure shall be applied also in production of light emitting buoys (Fig. 6), which can simply be made out of balls having on their wall module installation bed. Special module for installation into buoys shall be installed into the bed: Fig. 6, Position 1 (with element for binding of the anchoring cord), with light emitting system (the same as that for light emitting ball) or without it. Buoy with light emitting module can be used for marking of ships, beaches and similar under conditions of poor visibility, for night tracing of ships and marking of positions of scuba divers.

7. APPLICATION OF INNOVATION This innovation enables production of very practical and useful balls, which production can be carried out economically. It represents vital improvement when compared with standard ball.

Specialists shall evidently find out that this innovation offers numerous variations and options for application on similar products, without having to depart from its field of application and the basic intention of the innovation.
