Description

The invention relates to a dynamo system according to claim 1.

Such dynamo systems are used in human trekking activities, e.g. As when hiking, mountaineering or the like. Typically, to provide small electrical consumers such as bulbs directly with electricity or electricity storage, especially batteries of z. As mobile phones, navigation devices or portable PC's, to charge. For this purpose, pulling on a pull rope, whereby the dynamo shaft rotates and voltage is induced in a coil. Then the pull rope is rewound by a suitable mechanism.

There is a need that necessary for the operation of the pull rope movements in natural movements of Trecking activities, such. B. Hiking, integrate. In other words, already running movements during towing activities should be used to actuate the traction cable of a traction dynamo. The natural movements should not be significantly impaired; Pulling on the pull ropes should rather serve as a workout, in particular strength endurance training for the body part which actuates the pull rope in each case.

From the DE 299 20 007 U1 is a Zugseildynamo known at the pull rope one or more times to be pulled by hand, so that kurzeitig generated electricity and can be used to charge cell phones or laptops. To DE 10 2009 011 005 A1 is arranged on a backpack Zugseildynamo, provided for generating energy for a light source or for temporary storage in an energy storage. The disadvantage here is that only very briefly during the drawing power can be generated. The manual operation of the pull rope disturbs the natural movement of typical trekking activities and also has no training effect.

It is therefore the object of the invention to provide an improved dynamo system on the other hand, which allows a more efficient power generation, allows a better integration of Zugseilbetätigung in the natural movement in Trecking activities and also can be used as a mobile training device.

The object is achieved by the dynamo system according to claim 1.

The dynamo system according to the invention is characterized in particular by the fact that a second traction cable is provided for driving the dynamo shaft of the traction dynamo, wherein both traction cables are actuated independently, that is, the operation or movement of a traction cable can be decoupled from that of the other traction cable and vice versa. This makes it possible that while pulled on a pull rope, the other pull rope is not moved and vice versa. These are a Dynamohaltemittel for attaching the Zugseildynamos to a person or on a portable on the back of the human holder, z. B. in the form of a piece of luggage and arranged on the traction ropes rope holding means for attaching the traction ropes on people provided.

The Zugseildynamo dynamo system according to the invention can by means of the dynamo holding means on the body or the luggage and the traction cables such z. B. attached to the arms or legs of the human body that u. a. natural walking, walking and running movements with opposite movements of the legs or opposite pendulum movements of the arms for an alternating actuation of the traction cables and thus can be used for a continuous drive of Zugseildynamos. This enables continuous power generation without any disturbing movement during the trekking activities. The resistance of the dynamo wave to be overcome for operating the traction ropes also contributes to the body training of the human being. The dynamo system according to the invention can thus be used in trecking activities in the manner of a compact, power generating fitness device.

According to a first embodiment of the dynamo system according to the invention it is provided that the Zugseildynamo on the outside of a backpack and the rope holding means are fastened to the legs of the human. Particularly suitable is that side of the backpack, which is opposite to the intended for the concern on the back page. This arrangement of the Zugseildynamos a clear distance of the Zugseildynamos be created by the back of the backpack carrier in the sense of a projection. This protrusion prevents the pull ropes from gripping body parts on the back of the wearer. Furthermore, the projection allows a particularly advantageous guidance of the traction cables to the effect that the leg movements for the operation of the traction cables can be used very effectively.

Alternatively, the traction dynamo can also be attached to one of the legs or, more preferably, to both legs of the human and the rope holding means to the arms or hands of the human. This arrangement is particularly advantageous if the tension cables by pendulum movements of the arms, z. B. on expeditions in a tent, should be pressed. You can charge GPS devices, satellite phones etc. Furthermore, this arrangement possibility allows a particularly effective training of the arm muscles.

Preferably, the cable retention means comprise loops or straps, which are particularly flexible adaptable to different body dimensions and body parts. The Zugseildynamo can continue to a holder, for. As plastic, have a tether fastened thereto, which the traction dynamo particularly flexible to different body parts and brackets, in particular luggage pieces can be attached.

According to a further embodiment, a traction cable coil, a freewheel device and a return spring are provided. Particularly preferably, the components mentioned are present twice and each assigned to a pull rope. The traction cable coil can be coupled by means of the freewheel device with the dynamo shaft and rotatable against the return spring with unwinding of the traction cable. The traction cable can be wound onto the traction cable reel by means of the freewheel device.

The return spring, z. B. a coil spring, can generate a restoring force, which counteracts a tensile force resulting from actuation of the traction cables. Depending on which of the two forces mentioned is greater, an automatic coupling or decoupling of the dynamo shaft and the traction cable coil can be carried out particularly advantageously.

Furthermore, it is provided in particular space saving that the dynamo wave is hollow and in the cavity electronic components of the dynamo system are arranged.

Furthermore, the Zugseildynamo have a power supplied by him USB interface to which particularly many common small electrical consumers or power storage can be connected for example via appropriate cable for power supply. Other current outputs of different shape and output values may also be provided as required and required within the respective capacity of the tow rope dynamo.

It is furthermore particularly advantageously provided that an iron yoke with at least one magnet is fixedly arranged on the dynamo wave and rotatable relative to a stationary dynamo coil. The iron yoke and the at least one magnet form the rotor of the Zugseildynamos, the iron yoke is particularly advantageous as a flywheel. The stationary dynamo coil forms the stator of the tow rope dynamo. Without being limited to this, it is particularly advantageously provided that a circumferential iron yoke with internal permanent magnets is connected to the dynamo wave and rotatable relative to a fixed dynamo coil with claw pole sheet metal cages, which in particular makes a contribution, magnetic passages lead very well and to enable particularly efficient power generation.

The dynamo system 1 includes one in the 4 to 7 visible and in the 1 to 3 mostly hidden under an encapsulation K haulage dynamo 6 with two independently operable traction cables 7 made of nylon to drive the dynamo wave 8th of the traction dynamo 6 , In addition, at the dynamo wave 8th not shown operating means, for. As cranks, be provided for their rotation, by which they additionally or alternatively to the tension cables 7 can be driven. The directions of movement of the traction cables 7 are shown with dashed double arrows, each one pointing towards the thigh of the human 3 leading arrow direction the direction of actuation of the respective pull rope 7 represents and that of the thigh of man 3 leading arrow direction represents the direction of action of a restoring force, which by serving as a return spring coil spring 14 (please refer 5 ) of the Zugseildynamos 6 is produced.

By means of a serving as Dynamohaltemittel tether 9 is a holder 10 made of plastic of the Zugseildynamos 6 in the embodiment according to 1 and 2 on the backpack 2 attached in the lower part of the back facing away from the back 11 , By means of the free ends of the traction cables 7 firmly attached knee straps 12 , which serve as rope holding means, are the traction cables 7 on the thighs of man 3 attached, in each case in the knee area to the leg movements particularly effective for the operation of the traction cables 7 to be able to use.

According to the alternative dynamo system 3 is a holder 10 made of plastic of the Zugseildynamos 6 by means of a likewise serving as Dynamohaltemittel tether 9 on the thighs of man 3 attached, in the knee area of the thighs. By means of the free ends of the traction cables 7 firmly attached loops 13 , which serve as rope holding means, are the traction cables 7 on the forearms or the hands of man 3 attached to the arm movements particularly effective for the operation of the traction cables 7 to be able to use. The loops 13 can in particular also in the form of knee straps 12 be formed according to the first embodiment. The directions of movement of the traction cables 7 are shown with dashed double arrows, each one pointing towards the forearm of the human 3 leading arrow direction the direction of actuation of the respective pull rope 7 represents and the leading away from the forearm of the human arrow direction is the direction of action of a restoring force, which by serving as a return spring coil spring 14 (please refer 5 ) of the Zugseildynamos 6 is produced.

4 and 5 show details of in 1 to 3 largely hidden under an encapsulation K Zugseildynamos 6 , The ropes 7 are each a traction cable coil 15 , a freewheel device 16 and a return spring in the form of a spiral spring 14 assigned. To protect the traction cables 7 from damage, these run in the area to the traction cable coils 15 in sections in pipe guides 21 , The latter prevent chafing of the backpack 2 and the penetration of moisture, dust and dirt into the enclosure K of the Zugseildynamos 6 , Also, after putting on the backpack 2 are at the ends of the pull ropes 7 attached fasteners 24 easily accessible and can with the knee straps 12 get connected.

One of the pull rope dynamo 6 Powered and externally accessible USB interface 17 is arranged in the region of the encapsulation K. The USB interface 17 is supplied with direct current, which by means of a rectifying component, not shown in the Zugseildynamo 6 producible AC is recoverable. The USB interface 17 provides an output power of about 2.5 W to 5 W at a voltage of 5 V and a current of about 0.5 A to 1 A. They can not shown electrical consumers, eg. As smartphones, especially for charging their power storage via suitable cables or directly connected.

The dynamo wave 8th is in a ball bearing 22 stored, hollow executed and takes in their interior, not shown electronic components and a Pufferakkumulator (Li-ion accumulator) for the operation of the dynamo 1 on. A circumferential, ie 360 ° around the dynamo wave 8th around ironback 19 with permanent magnets 25 is non-rotatable with the dynamo wave 8th connected. Upon rotation of the dynamo wave 8th Therefore, the iron yoke also turns 19 with permanent magnets 25 , relative to a fixed stator coil 20 with pole claw metal cages 18 , in which then electrical voltage is induced.

6 and 7 show the dynamo system 1 to 4 with most of the encapsulation K hidden Zugseildynamo 6 , The holder connected in one piece with the encapsulation K 10 made of plastic has slots 23 on, through which the tether 9 is mutually guided. The tether 9 is still sideways around the backpack 2 tied around and is so firmly attached to him that the Zugseildynamo 6 firmly with the backpack 2 connected is. The connecting elements 24 the pull ropes 7 serve the releasable connection with the in 1 and 2 shown knee straps 12 and are identical to the ones in 3 illustrated hand straps 13 , The releasable fasteners 24 continue to form safety connections between the straps 12 or loops 13 and the ropes 7 which aforementioned components when an allowable load, eg. B. blocking the dynamo system 1 separate each other. This can be a threatening fall of the wandering man 3 be prevented.

The following is a preferred mode of the 1 and 2 respectively. 4 to 7 illustrated dynamo system 1 explained in more detail. Wander, climb, walk or walk 3 , so move his legs in opposite directions and the traction cables 7 are alternately operated, that is, when one leg moves forward and pulls on its pull rope, the other leg moves backwards and does not pull on its pull rope, but the latter is automatically withdrawn, and vice versa.

By pulling on a pull rope 7 during the forward movement of the leg this takes on a corresponding traction. Against the tensile force acts through the coil spring 14 generated restoring force. The spiral spring 14 is with the traction cable coil 15 coupled so that it is tensioned when the Zugseilspule 15 in driving direction of the dynamo shaft 8th (hereinafter: drive rotation direction) rotates.

A pulling force acts on the one pulling rope 7 , which is greater than the restoring force, so is the traction cable coil 15 rotated in the drive direction of rotation and the pull rope 7 from his traction cable reel 15 settled. The case by means of freewheel device 16 non-rotatable with the cable pulley 14 connected dynamo wave 8th is thereby driven in driving direction, so that the iron yoke 19 and the magnets 25 relative to the stator coil 20 with claw pole sheet cages 18 turn and in the stator coil 20 a voltage is induced. The spiral spring 14 is by unwinding the pull rope 7 from the traction cable reel 15 curious; excited.

During the backward movement of the leg takes on the pull rope 7 acting tensile force usually the value "zero" and is thus smaller than the restoring force, so that the freewheel device 16 the traction cable reel 15 from the dynamo wave 8th decoupled. The spiral spring 14 relaxes and twists while the traction cable coil 15 contrary to the driving direction of rotation, causing the pull rope 7 on the traction cable reel 15 is wound up. In the event that the tensile force is equal to the restoring force, the freewheel device decouples 16 also the traction cable coil 15 from the dynamo wave 8th because even when coupled the dynamo wave 8th not twisted. This is especially the case when the coil spring 14 is relaxed, no pulling force on the tow rope 7 acts and the latter with maximum number of turns on the Zugseilspule 15 is wound.

Through even leg movements of humans 3 and a correspondingly rapid winding of the traction cables 7 of the traction dynamo 6 assuming thus the dynamo wave 8th continuously driven by the dynamo system 1 uninterruptible power generated and the actuation of the traction cables 7 be used as a body workout.
