Description

TECHNICAL FIELD

The invention referred to herein concerns and describes an instrument to be used during educational and recreational juggling activities, consisting of a group of props that can be assembled in various ways.

BACKGROUND ART

The art of “poi” comes from the Maori tradition wherein codified movements using tethered weighted objects are performed during certain ceremonies.
Today, poi juggling consists of performing dance moves whilst at the same time spinning weighted objects of various shapes, also called «poi heads», around the body. These heads are attached to a link made of, for example, rope, chain, cloth, natural, synthetic or optic fibers. Poi are sometimes equipped with lights or fire elements.
The poi heads are classically spun and tossed whilst holding onto what are known as “classical” straps or handles, located at the other end of the link.
The art of poi has become highly developed, and numerous jugglers are now able to manipulate up to two poi in each hand. This is achieved by holding two classical handles or two straps in the palm of the hand, which is an uncomfortable thing. There are two problems with this technic; objects can be accidentally dropped, and it can provoke muscular pain due to prolonged periods of working against centrifugal force.
As things currently stand this practice entails a risk, not only to spectators, but also to the user himself, due to a lack of ergonomic comfort when trying to hold onto multiple classical handles.
It is already known the existence of “Meteor” juggling which consists of two weighted objects that are joined together by a link of varying length. In this case, there are neither handles nor modularity involved.
It is also known the existence of “Puppyhammer” which comes from the Shaolin School of martial arts and works in much the same way as meteor juggling, but the link is much longer and features knots which act as position markers.
Several children's games exist that use adjustable devices to be able to realize tridimensional complexes shapes, but none of these is adapted for juggling. Examples of such games are described in European Patent Nos 1348473, 1555056 and 1537901 or GB patent No 726328.
In any event, none of the juggling props currently available is designed to allow the poi heads and poi handles to be linked together in order to juggle various modules separately or together.
Apart from the fact that there are no such adjustable props available, none of the material currently on offer allows one to easily spin more than two poi in each hand. The scope of possibility offered to users is currently restricted in terms of technical diversity but also in terms of visual and artistic effect.
Lastly, and aside from the problems regarding the physical safety of both spectators and/or the user, it would be of great interest to facilitate the exploration of juggling techniques by offering all users the chance to easily customize and learn from his or her props. This would be achieved by providing an integrated training system allowing to record, share and display teaching technics and performances with a facilitating and interactive environment.
This invention sets out to resolve one or more, or even all of the above-mentioned issues.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a set of adjustable juggling props, each of which will remain securely attached. The desired number of links is fastened via any number of cohesive handles allowing the desired quantity of weighted objects to be spun around.
It is a further object of the present invention to improve the possibilities of achieving an ergonomically comfortable grip allowing new manipulation techniques whilst manually maintaining the spin of numerous weighted objects.
A third object of this invention is to enable various props assembly based on the desired number of modules and cohesive handles, which are joined together.
Another object of this invention is to enable the built of innovative juggling structures, using detachable and/or fixed fastening and/or attaching systems, whilst juggling.
It is still a further object of the present invention to offer the user the potential to vary his technique by offering a greater choice of elements making up the object that is to be manipulated.
Finally, a further object of this invention is to supply a user-friendly, reliable tool that can be customized to suit ergonomic requirements and that will encourage the exploration and sharing of juggling techniques. This will be done by using various electronic and mechanic integrated functions described more accurately in a further section.
All of the desired properties will be obtained by combining together in different ways the compatible elements that make up this invention.
The above-mentioned aims will be met by the set of elements comprising this invention. Thanks to the innovative functions of the modules, cohesive handles and links, it will be possible to perform a variety of new and complex juggling structures.
Regardless to all secondary functions, one of the main characteristic of the module is that it involves at least one fastening system that is either detachable or fixed, allowing each handle to be fastened.
The body of the modules can display any dimensions and shapes, such as, for example: a ball, a toroid, a gyroscope, gimbals, or a hoop.
The module might feature recesses and/or ergonomic holes able to integrate specific capsules, for example, ball bearings that will facilitate turning around the fingers, hands and/or around any of the user's limbs.
The fastening system is preferably a magnetic, self-adhesive fastening system or, alternatively, could also feature any type of mechanical fastener. This is not restrictive.
The configurations of said group of elements can be changed in accordance with the user's wishes by simply attaching or detaching the fastening systems described hereunder. The user can therefore choose which system to use according to the envisaged uses/practices.
For that matter, one can also envisage using remotely controlled fastening and/or detaching systems, implicating mechanical or electromechanical systems such as electromagnets.
In one particular mode of use, the fastening system is controlled via an on-board remote control unit lodged inside the module or a mechanical release button. This mode of use is allowing one to easily control the fastening system.
In a particular realization mode, said electronic and/or mechanical systems are preferably hold into removable specific capsules.
The module will preferably feature at least one sensor, for example a cinematic sensor, and the on-board remote control unit preferably logged in a specific capsule. Those capsules could be switched to change functionalities supported on the juggling set.
In a particular realization mode, it could be in communication with an outside source such as a computer, a tablet or a smart phone, so that data generated by the sensor(s) can be exchanged, recorded, treated and used in various ways. An example would be to control other functionalities such as lights, motors or gyroscopic devices depending on module's angular momentum or velocity.
The module will preferably feature a cavity, which will house the elements of a detachable and/or fixed fastening system when these elements are not in use.
In particular realization modes, the juggling module will feature one or more of the following elements:

- ball bearings
- gyroscopic spinning top
- motors
- fibre optic
- LED
- integrated circuits, connectors, slip rings . . .

Each of these elements will enable additional functions that will improve the juggling experience.
Various electronic sets could be proposed by the builder, preferably logged inside specific switchable capsules.
It would allow to easily switch modules properties or simply allow for discharged battery replacement using another capsule.
Preferably, the invention will also feature electronic circuits featuring one or more of the following elements:

- storage memory and/or

- an electric actuator providing functions aiming to coach the user's performance and/or
- a power supply

Furthermore, the module might feature specific capsules for pyrotechnic and/or mechanical system and/or a gyroscopic spinning top to enhance the visual experience of the user and spectators. It can also be adapted as a Control Moment Gyroscope (CMG) to allow for a feature that modifies the module's attitude or angular momentum.
The group of elements has the essential particularity of being able combine multiple module, handles, link and capsule properties for juggling.
Also, both the cohesive handles and the links can act as a support for all kinds of additional devices aimed at enhancing the user and spectator experience. For example, display devices, ball bearings, light features, fire features, sound or other features controlled either mechanically, electronically and notably remotely.
These additional functions, some of which are described hereunder will preferably be logged in specific capsules. It provides a convivial instrument aimed at measuring, recording, communicating, modeling, programming, but equally at helping the user to physically train whilst at the same time offering a wide variety of technical and aesthetic properties.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

The main function of the module is to serve either as a weighted object to be juggled, or as an ergonomic holding device of varying properties. It also allows for attachment to a defined number of cohesive handles according to the number of fastening systems involved.
The body of the modules can be printed, shaped or molded in a variety of materials and can be of differing sizes and geometric shapes according to the desired texture, visual effects and ergonomics.
The main function of the cohesive handles is to serve either as a way of connecting to a module, or as a manual holding device. The handles can also occasionally serve as objects to be spun.
The body of the cohesive handles can be printed, shaped or molded in a variety of materials and can be of differing sizes and shapes according to the desired texture, visual effects and ergonomics.
The main function of the link is to join two cohesive handles together, or to join a cohesive handle and a classic juggling element. It might be rigid, flexible, elastic, retractable, or other. It can be composed of one segment or several different segments, so long as it can withstand the force created by the modules in motion.
The link might be flexible and/or rigid, and/or elastic and/or other so long as it serves to hold the weighted objects together. It might be linear or feature multiple connections.
The detachable fastening system used to connect elements together whilst juggling is made up of two compatible sub-units. One of which is attached in variable number to the module and the other sub-unit is fixed to each cohesive handle.
In one particular realization mode, made possible by developments in miniaturization techniques, electronic circuits are placed in a housing or a capsule that is fixed to a support that is detachable or fixed onto the module bodies, within the body of the cohesive handle or even in the links.
There will also be a housing designed to contain an electronic battery and a charging system, or any other kind of generator allowing an energy source supply.
The modes of use, forms and systems listed hereunder are given as examples only. The aim is to illustrate a certain diversity in the main and secondary functions assured by the different elements. However, the modules, links, cohesive handles, detachable or fixed links, fastening systems and secondary functions presented here could also be obtain by other ways to ensure the same functions.
We will now describe how, in using this new kind of juggling material, one can significantly improve both safety features and user/spectator enjoyment by expanding technical diversity and artistic possibilities.
The building materials used could be any material that is adapted to the desired functions, bearing in mind particularly the need for the fastening systems to be able to withstand the force created by the act of juggling.
Furthermore, the ensemble might include a number of so-called secondary functions that will require the incorporation of various components, certain examples of which are described hereunder.
The invention might integrate different control systems such as visual or audio interfaces, mechanical, electro-mechanical or electromagnetic functions, but also all kinds of systems to measure impacts, position, acceleration, patterns, or such systems that are capable of modifying kinetic properties and/or the attitude of the set of juggling elements.
We will then illustrate a number of possible embodiments of the invention.

I. First Embodiment

In this first embodiment, as illustrated in FIGS. 1, 2 and 3, the elements are put together in one of their simplest form; there is no secondary function. The module is comprised of a ball with three detachable fastening sub-units with a 120° angle between them.
More specifically, FIG. 1 shows a cross section view illustrating the body of module 1 with three fastening systems, 10-1, 10-2 and 10-3 respectively, with a 120° angle between them. They are adapted to allow three handle bodies, for example the cohesive handle 3 with fastening system 5 to fix the link 6.
In this specific mode of use, fastening systems 10-1, 10-2 and 10-3 are detachable magnetic and/or mechanical fasteners.
As shown in FIG. 1, the fastening system 10-1 is made of two fastening sub-units 2 et 4, for example magnetic ones, respectively logged in corresponding recesses inside module 1 and cohesive handles 3. This allows a solid fastening which is however detachable whilst juggling between module 1 and its associated cohesive handle 3.
The cohesive handles illustrated in FIG. 1 are composed from a geometrically simple body 3, displaying a system allowing the fixation of sub-unit 4. This first sub-unit is design to fit with the sub-unit 2. This allows the fastening system 10-1. More generally, one could substitute the magnetic elements 2 and 4 with any other detachable mechanical fastening system. Moreover, distinct fastening systems could be combined 10-1 to 10-3, notably detachable and fixed whilst juggling, depending on user's needs.
The module's and handle's geometries are designed to fit all together. Each handle display a fixation element 5 for the link 6. The link-handle fixation should be well grounded in order to ensure no dropping whilst juggling. The fixation element could be grounded to the body of cohesive handle or to the fastening system 10-1.
In this mode of realization, the link is flexible and could correspond to any type of rope, chain, cloth, natural, synthetic or optic fibers or any other flexible link.
More specifically, the fastening system 10-1 could be constituted, as shown in FIG. 5 a, from a metallic fastening sub-unit 4 in the handle 3 facing a magnetic sub-unit 2 hold by the module 1.
In another particular embodiment, the fastening system 10-1 could be constituted with a magnetic sub-unit 4 hold by the cohesive handle 3, facing a metallic sub-unit 2 hold by the module 1. In both cases, the nature of fastening respective sub-units 2 and 4 must be defined and kept constant in order to achieve interconnectivity of all elements.
In another particular embodiment, the fastening system 10-1 to 10-3 could be constituted with two magnetic sub-units 2 et 4 presenting complementary poles.
Concerning this last case, the respectively exhibited polarities by sub-unit 2 hold by the module 1 and the complementary sub-unit 4 logged in the cohesive handle 3 must be defined and kept constant in order to achieve interconnectivity of all elements.
In another particular embodiment, the detachable fastening system could be constituted from any type of self-adhesive surface enabling a sufficient fastening. In this second case, the nature of fastening respective sub-units 2 and 4 must be defined and kept constant in order to achieve interconnectivity of all elements
However, certain types of fastening systems exhibit no polarities incompatibilities. This is the case for some kind of magnetic systems which presents both polarities on the same side. For example, a magnetic isolating setting will force the magnetic field to flow in and out on the same side of the magnet. In the absence of incompatibility problems, module-module or handle-handle fastening would be allowed, bringing even more diversity to the building possibilities
In all cited elements, fastening is done by a simple rapprochement of the magnetic sub-units 2 and 4. The release is done by a lateral pressure exerted on the cohesive handle. Shearing leads to sub-units release, ensuring a detachable fastening system.
Strong attractive forces are exerted perpendicularly to the surface of the magnet. This is allowing an easy release by lateral pressure while the exerted forces are not so strong. During normal use, fastening can only be released by the user's action. So, one can choose to build the needed association whilst juggling.
However, it will be preferred to associate various mechanical and/or fastening systems to ensure an optimal security. It is not restricted to magnetic fastening.
FIG. 2 show the considered elements, here dedicated to hold three classical poi 7. This is done by replacement of the classical handles with cohesive handles described herein.
It could also be possible to propose mechanical systems displayed on the handles that would serve as a universal fastening system and/or facilitating any juggling prop fastening (not represented).
FIG. 3 is a front view of the first mode of realization depicting a pool of elements comprising four modules and six cohesive handles. Here, the modules can serve as an ergonomically comfortable grip or as a weighted object. This is allowing the realization of new complex juggling patterns, spectacular and aesthetic effects.

II. Second Embodiment

FIG. 4 is a front view of the second embodiment illustrating exemples of the shape and property diversity enabled for modules. For exemple, some modules support various numbers of fastening systems. Modules can also display holes and recesses, holding bearings, a screen, LEDs, push-buttons or any other secondary functionality preferably hold into capsules.
Those functionalities could be changed by the user thanks to modular electronical or mechanical units such as capsules. More complex combinations could be made and it would facilitate multiple properties exploration.
The number of fastening systems per module is comprised between one and a complete module covering.
In a particular embodiment, the invention allows to easily switch between a fixed or detachable fastening system whilst juggling.
Generally, but not restrictively, whilst juggling a high number of modules, we recommend using a fixed fastening system, plugged before routine. A fixed connection between cohesive handles and modules allows the cohesion of complex structures previously assembled. By this mean, important forces can be applied to the juggled structure without risking to drop any module.
In contrast, whilst juggling a limited number of weights, we'll prefer the use of detachable fastening systems, allowing the established connections to be switched whilst performing. It would allow more technics and spectacular diversity.
FIG. 5a is composed of a cutting view schematizing the functional principle of the fastening system 10-1 detachable whilst juggling, regardless to the fixation mean to the handle's nor to the module's bodies.
In contrast, FIG. 5b is showing the fastening unit 8 which is fixed whilst juggling. That system could be substituted for the detachable fastening sub-units 2 and 4 previously shown in FIG. 5 a. In this case, each fixed fastening unit is composed with an element fitting in place of the detachable fastening sub-units, according to respective handle and module fixation systems.
Otherwise, the detachable/fixed fastening systems 10-1 to 10-3 but also fixation of elements 2 and 4, is done depending on the fastening system engaged. Various non limitative examples are given hereunder.
It could be judicious to allow one to have the choice of the fastening system in use. this would be done by switching between detachable/fixed fastening systems. It would ensure the needed maintaining in regard to the weight, the number of modules and the kind of routine performed.
Otherwise, as illustrated with more details in FIGS. 6, 7, 8, 9 et 10, the module's geometry can feature capsules, reliefs, grip or any other esthetic or functional elements that would optimize the ergonomic or modifying the technical and visual properties.
In a general way but without limitations, module's shapes but also the fastening systems repartition is design in a balanced way around the geometric center.
Juggling properties, module's shapes, colors and textures, could be chosen to fit each one's particular needs; for exemple kids, schools, beginner, professionals.
Module's shape will need to be adapted regarding to the properties featured. There is an imperative need that cohesive handle's shape fit with module's shape to ensure the security of the fastening system.
Then, it would be judicious to establish a normalized fastening system, allowing to connect any proposed element.
As it is also shown in FIG. 13, a module can possibly correspond to any ring or bigger hoop featuring or not a bearing system allowing the gravitation of several weights, in a hoop dance manner around the body.
Still as an example, FIG. 10 show in details a module which body features nested gimbals. It can host a gyroscopic motorized spinning top, modifying the physical properties of the module.
Furthermore capsules holding electronical or mechanical secondary functions could be fitted to the holes and recesses. This way, the user could add and switch the secondary functions holt by a basic module. The capsule could hold LEDs, a remote controller device or a ball bearing (61).
Finally, as illustrated with more details in FIGS. 8, 9 and 10, module's body could feature mechanical components, electronic circuits, motors, and other systems allowing pyrotechnical, luminous or any other secondary function. More functions will be described further as a non-limitative example list.

III. Third Embodiment

FIG. 6 is a fragmented view of a third embodiment, illustrating a cohesive handle 3 featuring a fastening sub-unit 4 on the top side and the element 5 allowing to fix the link 6 on the bottom side. Module's body 1 features three fastening devices separated by 120 degree angle. The body also features a hole 60 displaying here a ball bearing capsule (61). It could be any king of capsule holding secondary functions instead of a bearing. The figure also represent a fixed fastening unit 8 that fit in place of the detachable fastening sub-units 2 and 4.
FIG. 6 also represents the possibility for the handle body 3 or the link 6 to feature secondary functions.
Thus, any module could feature needed secondary functions by plugging capsules adding more properties to the elements. As illustrated, a module can feature holes 60 and a bearing capsule 61 allowing easy rotations around the fingers, wrist or any user's limb.
In another realization mode that could be independent from previous ones, bearings could be motorized.
Here, the module body features three fixation systems hold in nicks 63, and retained by a buttress retentions 62. The buttress allows fixing or removing of the magnetic element. This module body 1 is designed with through hosting the handle body 3 when fastened together.
Alternately, magnetic subunits 2 and 4 could be substituted by fixed fastening element 8. This way, fastening systems could be changed before juggling in regard to the routine expected. This would be done by choosing the appropriated fastening system. As shown in FIG. 6, a rotary eyelet 5 is used to hold the link 6 but also serve as swivel, avoiding link torsions whilst juggling.
In another embodiment that could be independent from others, some or all the fastenings could be definitively defined by the builder. In this case fastening sub-units and handle bodies could be suppressed. It could be like classical poi, meteors or any structure ready for juggling with one or more innovative functions proposed in this document.

IV. Fourth Embodiment

FIG. 7 is a fragmented view depicting a fourth embodiment. It is composed by a cohesive handle fixed to a link and by an openable module. This is allowing an easy storage and commutation of the unused fastening systems. Module closure is ensured by an elastic contention ring also serving as a handling grip.
It is expected to enable choosing between fixed elements 8 and detachable fastening elements 2 an 4. In this case, the module body features a loge 71 for unused fastening elements storage. This would avoid losing of the unused fastening.
In this embodiment, the module body and/or the handle body are open-able in any way to allow fastening systems manipulation.
The module body can feature any kind of fastening system as a magnetic, auto-adhesive, mechanical fastening or like here using a grip 72 band to ensure contention. The aim is to enable easy manipulation of the elements, so the module body aperture could be done by separating half modules or by having doors (not shown) enabling elements access and easy fixation.
In this specific embodiment, fixation of the fastening elements 2 or 8 are ensured by threads featured on the module. The thread is screwed in the notch 70 featured by the module. This is not a limitative way of fixing the fastening systems to modules but it provides an easy way to switch from fixed to detachable fastening systems.
Here, the fastening elements 4 and 8 are combined to the system fixing the link 5. An eyelet ensures a blocking function of the fastening systems in the body of cohesive handles 3 and also ensures link 6 retention.
It is clearly not a limitative example but it shows a way to design elements displaying new properties for an innovative juggling.

V. Fifth Embodiment

FIG. 8 is an exploded view of a fifth embodiment. The fastening system is composed by electromagnets powered by a battery and controlled via an electronic chip. The elements also feature optic connectors, embedded LEDs in module body but also optic fibers allowing light diffusion in the whole elements.
With this fifth embodiment, modules, handles and links features interesting secondary functions, which could be mechanically and/or electronically and/or remote controlled. It could display visual light effects such as a Led POV system.
Said functionalities could be controlled by buttons an/or a screen interface, a sonor interface or telecommunication protocols.
The fastenings are here controlled via electromagnets 80, but it could also be realized by using any electronically controlled mechanical system. Toward this aim, the module features batteries or accumulators or any electric generator 81. It also features an embedded electronic unit 82, electric actuators and command buttons. These functionalities could be holt into specific capsules.
Par ailleurs, les fonctionnalités annexes abritées dans cet exemple par le corps du module pourront être en partie ou complètement délocalisées dans des capsules interchangeables comme décrit précédemment.
As an exemple, module body features command buttons 83 for electromagnets control. Programming buttons 86 are used to interact with a displaying interface. Here it's a multi-media interface comprising a screen 85, a sound interface 87 and LEDs. This multi-media interface could be a component of the embedded tutorial system described further down in this document. Programmation buttons 86 could be any touch, rolling or classical buttons depending on needs.
LEDs are components of a light diffusion system 84 also comprising optical connectors and an electronic controller chip 82.
These light sources are also designed to fit with optical connectors 88 featured on the fastening units. This is allowing light diffusion and signals through cohesive handles 3 and links 6.
Here the link is composed with sheath optic fibers and rotatory optical connectors 89 ensuring light diffusion in the whole elements from one or multiple sources by avoiding link twist and constraints while juggling.
In a specific realization mode, all elements feature facilities for hosting the needed mechanical, optical and electronical components. Those components would be hosted in various pluggable capsules. This would be a great way to implement new functions and a nice improvement for juggling prop modularity.
In a particular embodiment, embedded electronics could be featured within handles and links.
Microprograms could be uploaded in a memory associated to a processor or microcontroller. As an exemple, it could display training programs using sounds, screen or LEDs light patterns to guide the user through exercises. The training applications of this fonctionnalities are limitless and steel remain to be developed. Some application exemples will be described further down in this document.
The fastening command as the secondary functionnalities could be controlled via various external devices. It could be any remote controller, as computers, tablets or smartphones, using telecommunication protocols.
In a specific embodiment, it is to consider using any device using bluetooth, Wi-Fi, ZigBee, HF or any other communication protocol. This could allow programmed data exchanges and specific interactions with users. It could result in some new “video game” gameplay.
It is not necessary to develop here the said communication protocols, well known from any skilled person.
Data processing could be realized on board and/or using an external device. Processors and/or microcontrollers, could analyse, generate and transfer data from and to the juggling props.
Exchanged data and instructions could control the fastening lock or release. But it could allow lightning control, sound control or choosing the pattern to be displayed on screen or LEDs and many more applications.
Communication means and data treatment could be used as a ludic training assistance. This would be of great interest for juggling practice and analysis. It could be helping building a specific prop structure and giving advices while using it. In this case, trainings are provided using data record and analysis.
The embedded electronic control chip is receiving data coming from various sensors logged in the module body or in a pluggable capsule or coming from any part of the prop as handles, links or remote controllers.
We'll describe further down in this document how the control devices could allow using electrical motors and actuators implicated in secondary functions a pyrotechnical lightning, microphone use, music displaying, sensors control and many more secondary functions.
Those examples are not limitative; they aim at illustrating the applications diversity and the potential of such props. It would take a great advantage from using various easy interfaces as internally or externally controlled functionalities.

VI. Sixth Embodiment

FIG. 9 is a fragmented view depicting a sixth realization mode. It shows a module body holding gyrometers, accelerometers, control moment gyroscopes (CMG) and the needed control system. As we use here four spinning tops, the control system should be using quaternion mode to control prop momentum.
In this example we show four wheels, but it could be using any number of spinning tops depending on the desired momentum control. Instead of CMG, inertia wheels could be used to the same purpose.
The link is segmented into rigid and flexible segments to enable pivot points. This would allow new circular moves leaded by CMG.
Module, handle and link are supporting LEDs and electrical connectors known as slip rings, avoiding torsions and allowing to power on the entire prop.
More specifically, the sixth realization mode shows segmented links featuring flexible parts 6 and rigid or semi-rigid segments 96 supporting LEDs 97.
Powering and/or functionalities are controlled via electrical connectors featured between modules 94 and cohesive handles 95.
The use of segmented links is modifying juggling properties allowing new practices described further. The example link shown here features three segments but it could be made of any number, any arrangement and any type of segments depending on needs.
In a specific embodiment, the link could be featuring a facilitating length adjustment system. It could be for example a furling roller featured on link segments, or inside the cohesive handle (not shown). Such a system would allow a greater modularity and an easier carriage in bags.
In this embodiment, the link is supporting power and information transmission between modules. It features electrical wires, contact connectors 94 and 95 but also rotatory connectors 98.
In a specific embodiment, an inductive or wireless transmitting system could be used in order to identify established connections. As an example, RFID proximity detection systems could be used to detect established fastenings.
For various reasons described in this document, it could be of major importance to measure, model, and share data recorded while juggling. For example, one could need to record or study a performance video while knowing each module's spatial positioning.
In this embodiment, the powering and control unit 93 features an inertia central for spatial positioning. This device well known from a skilled person is made from acceleration sensors, and/or a gyrometers and/or a compass. It allows to measure module's attitude, linear and rotatory moves. These functionalities will need a powering supply, a data memory system, and a data processing system.
The data record and/or treatment could be realized directly on the module or it could be realized on a deported device such as a smartphone, a computer, a tablet, or any data treating system. Such a prop would implement various new possibilities for the juggling community. For example, it allows data sharing between users. In consequence, it would lead to more accurate performance studies, reproductions and modeling.
It would allow to study each one's performances, greatly improving existing technical databases. It could even allow to study metadata, collected on users while they are juggling. It would inform anyone about users habits and characteristics.
For sure, in a more advanced embodiment, integrated circuits can be fitted with an improved spatial positioning system, such as a system of triangulation of the positions of each module or still scanning the environment of the user for an optimum modeling.
Finally, in a particular realization mode, the user could need to program and control prop's attitude while juggling. For example, it could allow autonomously performed trajectories or depending on user's moves and commands.
In this realization mode, CMGs featured on several modules would allow such performances. Angular momentum is controlled using inertia wheels or Control Momentum Gyroscope, preferably controlled in quaternion mode to avoid well known inefficiency singularity points.
The spinning top 90 of sufficient mass are rotated by primary motors 91. Forced precession are exerted on different axis thanks to secondary motors 92. Those secondary motors are inducing a torque exerted perpendicularly to both rotatory axes. Torques induced by these wheels could be programmed and controlled in order to serve as tridimensional steering wheel. Module's attitude could be influenced, spinning around the junction to the flexible part of the link.
In a particular realization mode, by using a vocal and/or a telecommunication interface, real time data could be provided to the users allowing a better control of the props. Data could be transmitted via IR, Bluetooth or any protocol, to be treated on a computer, tablet, smartphone or any other control device giving a feed back.
After recording and modeling performances using attitude sensors, it allows to program module's autonomous attitude to share an autonomous prop performance or a tutorial method. For exemple, it could be based on social networks and direct exchanges between users but also on centralized databases.
In another realization mode, multiple devices could be combined to realize new mixed position sensors, for example scanning the environment to ensure better tridimensional models.
This device could be programed to induce or reproduce trajectories and/or attitudes. In addition, this device could be used to ensure real time CMG control, depending on user and close environment, avoiding unwanted collisions. Many other CMG based applications remain to be developed.
FIG. 14 illustrate a use of modules, handles and links combined to an external command unit displaying data on a screen while juggling. In this case, exercises are provided as videogames but it could be displayed directly on the prop using a screen or sounds and LED codes.
As seen in FIG. 14, the user manipulates a previously described juggling module 200. It features sensors 210 recording position and/or velocity and/or linear and/or angular accelerations. It features electronic circuits 220 powered by battery (not shown). Electronic circuits feature Wi-Fi, Bluetooth, ZigBee or any other bidirectional communication chip.
It is not limitative, but various communication possibilities between connected elements are illustrated as examples with black arrows.
Data exchange between connected modules could use wires within links 600. It could also use communication protocols or external memory cards.
Not as a limitative exemple, FIG. 14 illustrate a user wearing a belt holding a position sensors and a transmitter-receiver 700. This belt could serve as a spacial reference allowing taking in account user's moves. Alternatively this calibration system could be replaced or complemented by a movement recognition protocol allowing identifying each user's maximal amplitudes or physical characteristics. It would serve as a basis to calculate elements positions. Those processes are described as examples aiming at improving an optimal performance modeling.
The module 200 is fastened thanks to the previously described system 10-1 (FIGS. 1 and 9), to one or more cohesive handles 300 holding at least a sensor 310 allowing motion capture using velocity and/or accelerations and/or angular momentum data recorded within handles. Moreover, the handle hold a secondary circuit 320 powered with an autonomous battery (not shown) ensuring wireless data transmission. Alternatively, the electronic circuit 320 could be a transmitter/receiver allowing communication in both directions.
FIG. 14 show an external control unit 400 featuring various electronic circuits as an antenna 410 and a transmitter/receiver unit 420 allowing to communicate with the module 200 and the handles 300.
Preferably, the external unit 400 features a microprocessor 430 with data bus and command addresses, allowing data exchanges with RAM, ROM or EPROM memory 440 and peripheral driver circuits 450. It also features displaying circuits 460 needed to control an external displayer such as a TV screen 500, any computer screen or LCD screen.
The microprocessor 430 is associated with a software loaded in the memory 440. It is aiming at displaying a juggling tutorial, using sensor data from modules 200, handles 300 and/or links 600. It allows external data treatment and an external training interface on the displayer 500.
During his routine, the user can see various textual and graphical data, giving feedbacks of major interest for the practice. Particularly, the external device 500 could display representative data, position data, acceleration data, timing data and many more sensor derived data.
The external unit 400 could exploit these data to generate derivate data such as codified colors and/or geometric patterns. This codification could allow an easy interface, displayed on the external screen 500 and/or directly on the module's screen 240.
In a particular embodiment, modules are featuring straps (not shown) to avoid any dropping that would inevitably cause domestic damages, notably when facing a screen.
In a particular embodiment, the executed software is a tutorial or a game with specific rules, allowing to go progressively through various tricks and technics. Specific rules could be implemented, depending on the assembled prop. It could be realized with the prop seen in FIG. 14 or any other assembly featuring any of the previously described secondary functions.
As a non-limitative example, a scoring system could be established, depending on the accuracy of the performance in regard to the asked timings and positions. In order to help the user, LEDs 230 could indicate various things such as relative position to the theoretical pattern by using color or blinking or even sound notifications. By this way, a color shift could be displayed on the prop when the move is not fitting the trained pattern.
Also as a non-limitative example, thanks to CMG it is possible to teach tricks in a slow motions assisted way. By analyzing the user's arm and/or wrist angulation, it is possible, based on mathematical models to induce in consequence a specific momentum to the prop. This process could be developed further to allow main stream accessibility to juggling technics with low hurting risks. It could be developed as a high tech yoga interface or as a kid friendly game. More contents and games would help growing the user community.
It is also possible to integrate physiologic sensor allowing recording various health data during user's routine, facilitating the warm-up and such things. Any other software, ludic or not, could be implemented in order to increase practical possibilities.

This module, destined to advise fire jugglers, could feature an automatic pyrotechnic lighting systems and/or a facilitating flame suppression systems (not shown).
The fuel reserve could also be replaced or mounted on a motorized spinning top. The various gimbals would spin around the spinning top depending on the user's routine.
In this example, the link is rigid and directly fixed to the cohesive handles, implicating new juggling properties.
In a specific embodiment, the prop could feature a system converting a part of the kinetic energy into disposable electric power. It could also be using an inductive wireless system to power the prop. This power would be stored and/or used within the various electronic functions.

The whole characteristics described in this document can be combined together. It would allow new object diversity with innovative properties, adding infinite ludic, video-ludic and didactic possibilities.

VIII. Training and Social Network

In our days, training methods concerning juggling and technical tutorials are wide spread on internet. It is natural to propose a user friendly device able to display those programs directly within the props. It would allow the user to follow those instructions in any environment, without facing a screen, avoiding any collisions.
In a specific realization mode, a sportive training system is based on integrated programs uploaded in the embedded memory. From an integrated or a distant interface, the user could follow instructions adapted to his level. Various integrated capsules could be sold by the fabricant.
As previously described, the user interface could comprise any sensor or visual displayer, any screen, button, commutator, LEDs, sounds, vocal or any other codified interface. The goal is to be able to choose the needed training program and to control various secondary functions such as music displaying or visual effects for example.
In a specific realization mode, user's routine could be recorded in order to make sharable contents on social networks. It would allow data sharing between users. A broad new generation of performances could be easily studied and reproduced via this innovative connected teaching media.
More specifically, it would be possible to upload various data on the previously described integrated memory. It may be official training programs from the constructor, from various organisms and/or exchanged directly between users, using module connectivity. Then it would be interesting to establish a data base, collecting, clustering and sharing those contents. This database would facilitate the choice for adapted tutorials to any level. The data system could comprise video data, vocal or musical data, spatial positioning or any other type of data.
The social aspect described here is not limitative; the aim of this section is to illustrate new agreements provided by this interconnected prop. However, many more application remains to be developed.

IX. Synthesis Over a New Juggling Art

As seen previously, the invention allows building new juggling structures with complex modulatory, ludic and esthetical innovative properties.
The invention is based on the possibility to recombine various elements. The assembly comprises one or more of the module elements and one or more of the cohesive handles elements fixed to links.
As illustrated in FIGS. 2, 3, 12 and 13, when adequate forces are engaged, detachable fastening allow efficient maintaining of the weighted objects whilst juggling. But it also allows an easy release of handles and modules when desired.
One goal of the invention is to remedy to the ergonomic problems of holding multiple handle while juggling classical props. This particular problem is solved thanks to this invention.
Another innovative aspect proposed by this invention is to enrich the concept of juggling props such as juggling poi, clubs or staffs by allowing the dissociation/association of module and handles using various link properties to make a tremendous diversity of new props. This allows juggling independently any part of the prop while they are usually monoblocs/monolythics.
We consider that, as illustrated on FIGS. 11, 12 and 13, the prop can be made of a plurality of elements with various properties each.
As an example, we will illustrate some combinatory possibilities and some handling modes made possible thanks to this invention when associating multiple elements.
Various ways to hold the props are available. As seen in FIG. 11, four modules are assembled to serve as weighted objects or as ergonomic grips. The assembly is also composed of three links and six cohesive handles used as fastening systems or manually handled.
Many innovative practices are made possible thanks to this invention. As illustrated in FIG. 12, some modules are manipulated by hand; others are used as weighted objects. The central one is maintaining the cohesion of the structure whilst juggling.
Finally we will consider, as illustrated in FIG. 13, three different assemblies. One is composed with four modules and six handles. The other one is composed with two modules and two handles. The last one is composed with a bearing hoop supporting two spinning modules. This figure illustrates potential configurations offering interesting and innovative manipulation modes.
In this example, the modules are featuring various geometries and sizes. Each one of them is particularly adapted to ensure specific physical and ergonomic properties.
As illustrated previously, modules but also cohesive handles and links can feature various characteristics modifying the ways the assembly is manipulated
As exampled in FIG. 6, a hole 60 is featured on the module modifying the ergonomic. A bearing 61 allow rotations of the assembly around the manipulator's body. A spinning top can modify angular momentum; gimbals will allow rotations around the spinning top etc . . .
Finally, as illustrated in FIG. 4, the combinations and properties offered by a large diversity of compatible elements is potentially infinite.
Such an assembly could be manipulated by multiple users and probably need the use of fixed fastening systems to resist against the strong exerted forces.
The invention is allowing new technical and artistic possibilities. The concept of modifying configurations leads to a new level of technical exploration. By modifying physical properties and using structural and secondary functions of each element, the user is allowed to perform with original objects displaying the desired physical and esthetic properties.
Many programs and games remain to be developed on this support. Associated with an internal/external interface it could allow adapted uses for everyone attempting to learn from juggling disciplines. It is the next generation of physical training systems, interfacing between physical object properties and the virtual world. It is the first augmented reality juggling device, integrating modularity.
