Description

Dynamo system for trekking activities

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

Comparable dynamo systems are used in human trekking activities, such as hiking or mountaineering typically to direct electrical small consumers such as bulbs to power or recharge electricity storage, especially batteries of portable devices such as mobile phones, navigation devices or notebooks. For this purpose, usually a Dy ^¬ namowelle is driven by means of a pull rope and induces a voltage in the dynamo coil.

From DE 299 20 007 Ul a Zugseildynamo is known to be pulled on the pull rope one or more times by hand, so that kurzeitig current is generated, which can be used to charge cell phones or laptops. According to DE 10 2009 011 005 AI a arranged on a backpack traction dynamo, for generating energy for a light source or for charging an energy storage device is provided. The disadvantage here is that only very briefly during the pulling on the traction cable power can be generated. The manual operation of the pull rope disturbs the natural movement of typical trekking activities and also hardly serves the physical exercise. It is therefore the object of the invention to provide an improved contrast dynamo system, which allows for more efficient power generation, a bes ^¬ sere integration of Zugseilbetätigung in the natural motion during trekking activities

allows and thus 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 ^¬ sondere by the fact that a second traction cable to at ^¬ drive the dynamo shaft of Zugseildynamos is provided, wherein both lift cords are independently betae ^¬ tigbar, that is, the actuation or movement of a traction cable is of the other pulling cables entkop ^¬ pelbar and vice versa. This makes it possible that while ^{¬ is} pulled on the one pull rope, the other pull rope is not operated and vice versa. For this purpose, a Dynamohaltemittel for attaching the Zugseildyna ^¬ mos to a person or on a portable on the back of the holder, eg in the form of a backpack and arranged on the traction ropes Seilhalte ^¬ means for attaching the traction cables are provided on people.

The Zugseildynamo dynamo system according to the invention can be connected by means of Dynamohaltemittel so with the Kör ^¬ per person and the traction cables can By means of the rope holding means such as attached to the arms or legs of the human body that, inter alia, natural walking, walking and running movements with opposite movements of the legs or opposite oscillations of the arms for a starting ^¬ changing operation of the traction cables and thus for a continuous Drive the Zugseildynamos can be used. This allows continuous power generation without disturbing the person during the trekking activities. The resistance of the dynamo wave to be overcome for actuating the traction ropes makes a quite desirable contribution to the body training of the person. The dynamo system according to the invention can thus be used in conjunction with trekking activities in the manner of a compact, stream

generating fitness device are used.

According to a first embodiment of the dynamo system according to the invention it is provided that the Zugseildyna ^¬ mo on the outside of a backpack and the

Rope holding means are attachable to the legs of the person. Particularly suitable is the outside of the jerk ^¬ sacks, which is opposite to the intended for the concern on the back ^¬ NEN side. Due to this arrangement of the Zugseildynamos a greater 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 Guiding the tension cables to the effect that the Beinbewegun ^¬ ^¬ gen can be used for the operation of the pull ropes particularly effect fully.

Alternatively, the Zugseildynamo also be attached to one of the legs or more preferably each Zugseildyna ^¬ mo on both legs of the person and the rope holding means on the arms or hands of the person. This arrangement is particularly advantageous when the traction cables are to be actuated by pendulum movements of the arms or by a person lying on his back. You can charge GPS devices, satellite phones etc. At the same time, this arrangement 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 traction ^¬ dynamo can also be a holder, for example made of plastic, for a tether fastened thereto

have, with which the Zugseildynamo particularly flexible on different body parts and brackets, in particular luggage, can be attached.

According to a further embodiment, a traction cable coil, a freewheel device and a return spring are provided. Particularly preferred are the said Kom ^¬ components are present in duplicate and each associated with a traction cable. Each cable reel is connected by means of the freewheel device coupled to the dynamo shaft and rotatable against the return spring with unwinding pull rope. The traction cable can be rewound onto the traction cable reel by means of the freewheel device.

The return spring, for example a spiral 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 outweighed, an automatic coupling or decoupling of dynamo shaft and traction cable coil can be particularly advantageous, so that the driving tensile force and the opposite tensile force of the return spring from ^¬ change.

A particularly advantageous embodiment in this case is that the return spring is axially offset to the traction cable coil mounted on the dynamo shaft. In this case, the traction cable coil sits on a freewheel on the Dy ^¬ namowelle, such that the traction cable coil with the Dyna ^¬ mowing wave in the pulling direction of the traction cable is coupled coupled and decoupled against the pulling direction.

Is the tensile force in a rope greater than the back ^¬ force, the corresponding Zugseilspule is coupled with ^¬ means of the freewheel device with the dynamo shaft and the latter is driven, whereby the train ^¬ rope unwinds from its Zugseilspule. If the restoring force in a traction cable is greater than the traction force, then the associated traction cable coil is decoupled from the dynamo shaft by means of the freewheel device, and the traction cable is wound onto its traction cable spool against the drive direction of the dynamo shaft.

Furthermore, the dynamo wave can advantageously be mounted on a stationary hollow shaft via a ball bearing. In the cavity, electronic components and possibly also a Pufferakkumulator the dynamo system can be installed to save space.

Suitably, the Zugseildynamo have a power supplied by him USB interface, wel ^¬ che usual small electrical consumers or power storage for the power supply can be connected. Also, current outputs different form and with other initial values may be provided as part of the respective performance of the Zugseildy ^¬ namos depending on requirements and needs.

Particularly advantageous is further provided that an iron or metal yoke with at least one magnet fixed to the dynamo wave and is rotatable relative to a fixed dynamo coil. The iron yoke and the at least one magnet thereby form the rotor of the Zugseildynamos, the iron ^¬ inference is particularly advantageous as a flywheel. The stationary dynamo coil thus forms the stator of the Zugseildynamos. Without being limited to may be the rotor via internal permanent magnets connected to the dynamo wave and be rotatable relative to the fixed dynamo coil, which is provided with Klauenpol- sheet cages, to allow a particularly efficient power generation.

Pull ropes 7 firmly attached loops 13, which serve as a cable holding means, the traction cables 7 are attached to the Un ^¬ ter arms or the hands of the person 3 in order to use the arm movements particularly effective for the operation of the traction cables 7. The loops 13 may be formed in particular in the form of the knee straps 12 according to the first embodiment. The directions of movement of the lift cords 7 are displayed with gestrichel ^¬ th double arrows, wherein each leading into Rich ^¬ processing of the forearm of the person 3 direction of the arrow represents the direction of operation of the respective traction cable 7 and the leading away from the forearm of the person direction of the arrow represents the direction of action of a restoring force which is generated by serving as a return spring coil spring 14 (see Fig. 5a) of the Zugseildynamos 6.

4 and 5a, 5b, 5c show details of the in most of Fig. 1 to 3 in a housing capsule K ^¬ built traction dynamo 6. The provided on both sides of the housing capsule K traction cables 7 are each a traction cable 15, a freewheel device 16 and a return spring 14, z. B. assigned in the form of a coil spring. The dynamo shaft 8 is mounted on a stationary hollow shaft 27 via a ball bearing 22. The traction cable 15 is coupled via the freewheel 16 with the Dyna ^¬ mowelle 8 in the pulling direction of the pull cable 7 and connected decoupled against the pulling direction. The return spring 14 is anchored to the housing capsule K and connected to the Zugseilspule 15. The traction cable coil 15 is coupled to the dynamo shaft 8 via the freewheel device 16. The traction cable 7 is tensioned by means of the laterally of the traction cable 15 on the Dynamowelle 8 angeord ^¬ Neten return spring 14 which is supported relative to the housing capsule K.

FIGS. 5b and 5c show two embodiments of the Zugseilspule 15, a (Fig. 5b) with strip-shaped train ^¬ rope 7, another (Fig. 5c) 7 with schnurförmigem train ^¬ rope According to Fig. 5c increases the angular acceleration in accordance with the decreasing Coil diameter with the extension length, so that a largely smooth Be ^¬ drive the dynamo is possible.

To protect the traction cables 7 from damage these run in sections in pipe guides 21. The latter prevent chafing of the backpack 2 and the ingress of moisture, dust and dirt in the Ge ^¬ housing shell K Zugseildynamos 6. In addition, after applying the backpack 2 at the ends the tension cables 7 mounted fasteners 24 (FIG. 6) well ^{¬ he} achievable and can be connected to the knee straps 12.

One of the Zugseildynamo 6 can be supplied with power and accessible from the outside USB interface 17 is arranged in the Be ^¬ rich housing capsule K. The USB interface 17 can be supplied with direct current, which is generated by means of a rectifier, not shown, from the alternating current which can be generated in the traction dynamo 6. The USB interface 17 provides a Output power of about 2.5 W to 5 W at a voltage of 5V and a current of about 0.5 A to 1 A. They can not shown electrical consumer ^¬ cher, such as smartphones, especially for charging their power storage on suitable Cable or directly be ^¬ closed.

The dynamo shaft 8 is supported via a ball bearing 22 on a fixed hollow shaft 27, the electronic components are not shown in their attachments ^¬ ren and ei ^¬ NEN buffer accumulator (Li-ion battery) for

Operation of the dynamo 1 can record. An umlau ^¬ fender, ie 360 ° around the dynamo wave 8 around extending iron yoke 19 with permanent magnets 25 is rotatably connected to the dynamo wave 8. Upon rotation of the dynamo-wave 8, therefore, the iron yoke 19 also rotates with permanent magnets 25, relative to a fixed Polklauen- with steel cages 18 provided stator coil 20, in which the electrical voltage is induced.

6 and 7 show the dynamo system 1 according to FIG. 4 with traction dynamo 6 largely surrounded by the housing capsule K. The holder 10 connected in one piece with the housing capsule K has slots 23 through which the holding belt 9 is guided alternately. The tether 9 is further bound laterally around the backpack 2 around and is so firmly against him and si ^¬ chert the firm connection of Zugseildynamos 6 with the backpack 2. The connecting elements 24 of the traction cables. 7 serve the detachable connection with the knee straps 12 shown in FIGS. 1 and 2 and are identical to the hand loops 13 shown in Fig. 3. The releasable connecting elements 24 form safety connections between the tethers 12 and loops 13 and the traction cables 7, the aforementioned components when an allowable load is exceeded, eg when blocking the dynamo system 1 are separated from each other. Because ^¬ by an impending fall of the wandering person 3 can be prevented.

In the following, a preferred operating mode of the dynamo system 1 represented by FIGS. 1 and 2 or 4 to 7 will be explained in more detail. When walking, mountaineering, walking or running the person 3, the legs move in opposite directions to each other and the traction cables 7 are alternately betä ^¬ taken. If 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 wound up automatically, and vice versa.

By pulling on a pull rope 7 during the forward movement of the leg, it generates a corresponding tensile force. Against the tensile force acts a restoring force generated by the return ^¬ spring 14. The Rückstellfe ^¬ the 14 is with the traction cable 15 so

couplable that she will be curious when the

Traction cable 15 in the drive direction of the dynamo shaft 8 (hereinafter: driving direction) rotates. If a tensile force acts on a traction cable 7 which is greater than the restoring force, then its traction cable spool 15 is set in rotary motion in the drive direction of rotation and the traction cable 7 is unwound from its traction cable spool 15. The non-rotatably connected by means of a freewheel device 16 with the traction cable coil 15 Dynamowelle 8 is because ^¬ driven in driving direction, so that the iron yoke 19 and the magnets 25 rotate relative to the stator coil 20 with Klauenpol sheet cages 18 and in the stator coil 20, a voltage is induced , The return spring 14 is tensioned by the unwinding of the pull cable 7 from the tension cable coil 15.

During the backward movement of the leg, the pulling force acting on the traction cable 7 generally assumes the value "zero" and is thus smaller than the restoring force, so that the freewheel device 16 decouples the traction cable spool 15 from the dynamo shaft 8. The return spring 14 expands and In this case, the traction cable spool 15 is rotated counter to the drive rotational direction, whereby the traction cable 7 is wound onto the traction cable spool 15. In the event that the traction force is equal to the restoring force, the freewheel device 16 also decouples the traction cable spool 15 from the dynamo shaft 8. This is the case when the return spring 14 is relaxed, no tensile force acts on the pull cable 7 and the latter is wound with maximum number of turns on the pull cable coil 15 ^¬ . By uniform leg movements of the person 3 and if one assumes a correspondingly rapid winding movement of the traction cables 7 of Zugseildynamos 6, thus the dynamo shaft 8 can be driven continuously and generated by the dynamo system 1 uninterruptible power.
