Definitions
- the invention relates to a traction transmission device, in particular a traction rod, for transmitting a traction force from a traction device, in particular comprising a traction harness for a running person or a trailer hitch of a vehicle, to a child trailer and a system comprising such a traction transmission device.
- transmission devices for transmitting a tractive force of a traction device, e.g. B. a harness for a running person on a child trailer are known in principle.
- cargo trailers (especially child trailers that have a receiving device for receiving at least one child) can be directly (e.g. via a harness, e.g. a belt system) or indirectly (e.g. via a bicycle or other vehicle) to be pulled.
- load trailers (child trailers) are often attached to the harness or bicycle by means of a tow bar or a drawbar in order to enable the transmission of tensile forces and a constant distance between the (pulling) person and the trailer. If the pulling person moves in order to pull the trailer, the corresponding movements are normally transmitted undamped to the child trailer and can trigger vibrations that are unwanted, disruptive or even dangerous for the child.
- non-uniform movements of the person pulling in particular the hips of the person pulling, in the direction of movement or in the vertical direction can be problematic.
- the child trailer transmits (undesirable) movements or vibrations to the person pulling, which can impede the person pulling, in particular their walking movements.
- US Pat. No. 8,091,899 B2 shows a traction transmission device (or traction rod) which is or can be connected via a (flexible) connection device to a traction harness for the person pulling.
- the flexible connection device is designed specifically as a flexible line. This flexible leash is surrounded by rigid links that can move in opposite directions.
- the connecting device extends over a comparatively wide area and therefore requires a comparatively large amount of space. Furthermore, a large number of mutually movable links is necessary, which is comparatively expensive and can lead to a susceptibility to errors.
- US Pat. No. 9,840,266 B2 discloses a curved pull rod which is designed to be flexible in order to dampen vibrations that are generated. For this reason, US Pat. No. 9,840,266 B2 is restricted with regard to the choice of material. The material that is required is usually comparatively expensive or complex to process. In the event of a defect, the pull rod must (at least almost) be completely replaced. Furthermore, US Pat. No. 9,840,266 B2 also shows a connecting device in which the pull rod can have a damping element in relation to the retaining harness. The problem with this damping element is that damage can occur, in particular due to the unrestricted load, and this can result in (unintended) destruction of the connection between the towing harness and the towing rod.
- WO 2018/148826 A1 discloses a pull rod which can be folded in on itself. In a state of use, a joint for folding is fixed, so that no relative pivoting between the two mutually foldable sections is possible in the state of use.
- a leaf spring is shown within a connection between the traction device and the belt system (similar to US Pat. No. 9,434,401 B2).
- movements between the person pulling and the child trailer should be decoupled as simply and effectively (and yet safely) as possible.
- a traction transmission device for transmitting a traction force from a traction device, preferably comprising a traction harness for a running person or a trailer hitch of a vehicle (or the vehicle itself, possibly including a trailer hitch), to a cargo trailer (preferably a child trailer ), comprising: a first section with a first and a second end, a second section with a first and a second end, one of the first ends (of the first and second section) being connected or connectable to the cargo trailer (child trailer) and a the other (or the other) of the first ends (of the first and second section) is or can be connected to the traction device, the second ends (of the first and second section) being connected via a connecting device, preferably comprising a joint, in such a way that a relative Movement, preferably relative pivotal movement, is permitted between the second ends (of the first and second sections) in a state of use of the traction transmission device.
- a connecting device preferably comprising a joint
- a first (independent) aspect of the invention lies in particular in dividing a tension transmission device (tension rod) into two sections in such a way that these can also be moved relative to one another when in use.
- a state of use is to be understood in particular as a state in which the traction transmission device is used in such a way that the cargo trailer (or child trailer) can be pulled by the traction device (in a controlled manner). In this sense, a state such as that in WO 2018/148826 A1, for example, in which the joint described there is not locked, would not be a state of use (because then the tension transmission device or tension rod shown there could not be used sensibly).
- a fundamental idea of the invention therefore lies in the subdivision of the tension transmission device into at least two sections (namely the first and the second section), with the two sections in turn (in particular also or only in the state of use) being movable relative to one another, in particular being pivotable relative to one another .
- a connecting device is to be understood in particular as a device that holds the parts to be connected together.
- the (respective, in particular also the first and second explained below) connecting device should be able to hold the respective parts (sections) together independently (i.e. even if, e.g. in the case of a first connecting device, further connecting devices, such as a second connecting device thinks away or omits them).
- a damping device is preferably assigned to the connecting device in order to damp the relative movement, in particular relative pivoting movement.
- the damping device is preferably a component of the connection device, ie it contributes in particular to the connection.
- connection device can comprise a first and a second connection device.
- the first and second connecting devices are preferably (in particular each) designed in such a way that they (in principle) can hold the sections to be connected together (at least in a non-use state in which there are no tensile forces), possibly in such a way that the connection can only be made by crossing a predetermined force (e.g. at least 5 N) and/or (only) by applying a force not directed in the direction of pull and/or by destruction.
- both connecting devices can interact in such a way that, when in use, they realize a sufficiently stable and secure connection of the respective sections to be connected.
- the first connecting device preferably enables the relative movement (pivoting).
- the second connecting device can restrict the relative movement (in particular the relative pivoting) to a predetermined range of movement (pivoting angle).
- the first connecting device alone (i.e. without taking the second connecting device into account) enables movement (in particular pivoting) in a predetermined range (in particular pivoting range, possibly also unrestricted pivoting), which predetermined range is limited by the second connecting device .
- the first linkage were omitted, the first linkage (and the structure as a whole) would preferably allow for more movement (e.g., a greater angle of adjustment).
- the pivoting angle then made possible can be 1.3 times, preferably 2 times, possibly at least 3 times as large as the actual pivoting angle to which the movement is limited by the second connecting device.
- the damping device can be assigned (only) to the first or (only) to the second connecting device, or to both the first and the second connecting device. Assignment to the (respective) connecting device means that the damping device at least contributes to the connection (or the holding together) or at least defines it.
- the end of the first or second section can preferably be (reversibly) detachably connected to the towing device or the child trailer.
- the first end of the first or second section is not (non-destructively) releasably connected to the towing device or the child trailer.
- a traction transmission device for transmitting a traction force from a traction device, preferably comprising a traction harness for a running person or a trailer hitch of a vehicle (or the vehicle itself, possibly including a trailer hitch) to a cargo trailer (child trailer ), preferably according to the above first aspect, comprising: a connecting device for connecting a first and a second section, one of the two sections being part of the traction transmission device or the traction device, and the other of the two sections being part of the traction transmission device or the child trailer, the Connecting device comprises a first connecting device, which allows a relative pivoting of the two sections against each other and a second connecting device, which allows the relative pivoting to a predetermined movement range limited and/or cushioned.
- a limitation of the relative pivoting means in particular that the second connecting device limits the pivoting to a predetermined pivoting angle range, although the first connecting device would allow a larger pivoting angle range (if the second connecting device were not considered).
- the second connecting device is designed so that a through the first Connection device allowed pivoting movement is transmitted only damped.
- a torque that is required for (relative) pivoting can be twice as high, for example, by the second connecting device (or by a damping device assigned to it) in a (any) contiguous angular range (D) of, for example, at least 2° or at least 5° be compared to a case in which the second connection device (or a corresponding associated damping device) is not provided.
- the second connecting device should preferably be designed in such a way that it alone can hold the two sections together (although this does not necessarily correspond to a state of use).
- the first connecting device preferably comprises a (bearing) axle.
- the second connecting device preferably comprises a guide device within which an engagement device is movable (the movement of the engagement device being limited by the guide device).
- a second aspect of the invention it is therefore particularly proposed to connect the connection of two sections within a system (comprising a child trailer, a traction transmission device and a traction device) via two connection devices, with one of the two connection devices being able to (relatively) pivot the two connected Allows sections, which in turn is restricted by the second connection device.
- the child trailer can be towed in a comparatively comfortable manner in a safe and yet compact manner.
- the first and/or second section is/are preferably (at least essentially) rigid (or inherently dimensionally stable).
- the first and/or second sections are (at least substantially) inelastic. This should preferably be understood to mean that the modulus of elasticity of the material or materials (which together make up at least 90%, preferably at least 98%, possibly 100% of the weight of the respective section) of the respective section is at least 1 GPa, preferably at least 10 GPa, possibly at least 25 GPa.
- the first and/or second section can have a length of at least 15 cm, preferably at least 30 cm, optionally at least 35 cm and/or less than 100 cm.
- the first section can have a length which is at least 0.5 times, preferably at least 0.75 times and/or at most 2 times, preferably at most 1.5 times the length of the second section.
- the first and second sections can (in the connected state) define at least 60%, preferably at least 90%, of the length (possibly the full length) of the tension transmission device (in particular tension rod).
- the (respective) length is to be understood in particular as the maximum possible distance of a pair of points from all pairs of points of the (respective) section or element.
- the tension transmission device (tension rod) can have a length of at least 40 cm, possibly at least 65 cm and/or at most 200 cm.
- the first and/or second section can (at least predominantly) be made entirely of metal and/or plastic, in particular fiber-reinforced plastic.
- the first and/or second section can form a profile (solid profile or hollow profile) or tube (straight at least in sections and/or in particular curved at least in sections).
- the first and second sections are preferably connected to one another in such a way that (at least when in use) they can only be moved relative to one another via a relative pivoting movement (ie in particular cannot be moved towards one another via a translatory or purely translatory movement).
- the pivot axis can preferably lie in the connecting device (in particular in the first or the second connecting device), but according to the embodiment it can also lie outside of the connecting device and possibly also outside of the tension transmission device.
- the first and second section can be pivoted relative to one another about an axis that is particularly rigid (preferably at least substantially horizontal at least when in use). This (rigid) axle is preferably part of the first connecting device.
- the damping device can include at least one spring device (or precisely one spring device).
- the spring device preferably comprises or is preferably formed by: an elastic element, wherein the elastic element preferably consists at least partially of an elastomer, and/or at least one helical spring and/or at least one leaf spring and/or at least one torsion spring.
- the elastic element (in particular if it is formed by an elastomer) can have an E module (at 20° C.) of less than 1 GPa, more preferably less than 0.5 GPa, even more preferably less than 0.1 GPa. If the elastic element consists of different materials, this preferably applies to at least one material, possibly to all materials, or at least to materials that together define at least 90% of the total weight. According to the embodiment, however, the elastic element can also have a comparatively large modulus of elasticity, for example if it is a spring (e.g. steel spring).
- the respective conditions preferably apply at least for one direction (in the case of anisotropic materials).
- the modulus of elasticity at 20 °C should preferably be used.
- the connecting device in particular the second connecting device, preferably comprises a guide device (in particular with at least partially round or oval internal cross-section) and an engagement device movable within the guide device (in particular with at least partially round or oval external cross-section).
- a round or oval inner cross-section of the guide device there can also be a slot-like inner cross-section (in particular an inner cross-section which is arcuate at least in sections, possibly describing the section of a circle).
- a damping device in particular comprising an elastic element (preferably at least formed by an elastomer) may be arranged.
- the two sections to be connected are preferably connected to one another via the first connecting device, in particular rotatably mounted (with respect to one another) so that rotation about an axis (preferably lateral with respect to the direction of movement and/or horizontal in the position of use) of the sections is permitted in relation to one another.
- Rotation about a vertical axis (with respect to the direction of advancement or in the state of use) and/or an axis in the direction of advancement (in the state of use) is preferably (already) prevented by the first connecting device.
- all degrees of freedom are (already) taken by the first connecting device of the (relative) movement of the two sections to one another, except for the rotation about a lateral or horizontal axis of the sections to one another.
- a continuous axis (physically at least partially independently formed) can be formed on one of the two sections.
- the other of the two sections can have a through-hole (in particular through-hole) for mounting the axle.
- the two sections are preferably connected to one another by the second connecting device in such a way that one of the two sections has a guide device (guide element) that encompasses or at least partially encompasses (a first recess, in particular in the lateral direction) and within which (in particular within its recess) a Engaging means (engagement element) of the other section is performed (by engaging in the recess).
- a guide device guide element
- a Engaging means engagement element
- a damping device is preferably provided (at least in sections) between the guide device and the engagement device in order to dampen the (relative) movement of the engagement device in the guide device.
- the damping device can also be assigned to the first connecting device, for example, and can be designed, for example, as a rotary or torsion spring.
- the area of restriction of the relative movement (pivoting or rotational movement) is determined or specified in particular by the geometry of the guide device and/or the damping properties of the damping device (the elastic element).
- the guide device can be designed as a sleeve, for example.
- the engagement device preferably extends continuously through the guide device (in particular its recess). A configuration that deviates from this, for example as a socket, is also possible.
- the damping device (in particular the elastic element) can completely or partially fill an interior space or the recess of the guide device, in particular in a cushioning manner.
- a coupling for example via springs, is also possible.
- the elastic element is at least partially made of an elastic material (in particular elastomer), this preferably rests at least in sections on an inner surface of the engagement device (or its recess) and/or itself has a (second) recess, with the guide device itself further preferably extends completely or at least partially through the second recess and further preferably (directly) bears against the elastic element (or the elastic material).
- the second recess can also subdivide the elastic element (or elastic material) into two separate elements.
- the elastic element can consist of one body (in one piece or monolithic) or of several bodies (possibly separate or spaced apart from one another).
- the elastic element should then preferably be arranged in the engagement device (or in its recess) in such a way that it is compressed at least in sections (and/or at least expanded in sections). If the elastic element is an elastic material, the engagement device can have a cross section without edges (in particular a round or elliptical or oval cross section). As a result, it can be prevented in a simple manner that the elastic element (or its material) is subject to excessive mechanical stress.
- the engagement device transmits the forces occurring as a result of the movements to the elastic element (possibly the elastic material, in particular the elastomer), as a result of which a damping effect is achieved.
- the material is matched in such a way that no natural vibrations can be excited during normal use (i.e. in particular when the person pulling the child is moving at the expected speeds and taking into account the weight of the child trailer, including the load and the length of the traction transmission device).
- the (possibly physically pronounced), in particular lateral, axis and the guide device can be assigned to the first section, while the engagement device is assigned to the second section, which is mounted rotatably about the (lateral) axis.
- the (possibly physically pronounced), in particular lateral, axis and the engagement device can be assigned to the first section, while the guide device is assigned to the second section, which is mounted rotatably about the (lateral) axis.
- the (possibly physically pronounced), in particular lateral, axis and the guide device can be assigned to the second section, while the engagement device is assigned to the first section, which is mounted rotatably about the (lateral) axis.
- the (possibly physically pronounced) lateral axis and the engagement device can be added to the second section be assigned, while the guide device is assigned to the first section, which is mounted rotatably about the (lateral) axis.
- the (lateral) axis is not (fixedly) assigned to either of the two sections, but is an independent component.
- a possible configuration for this would be one pin or two interacting pins.
- the tension transmission device in particular the tension rod, and/or its first and/or second section can run straight at least in sections (possibly over the entire length).
- the damping device can be arranged at different positions of the tension transmission device, but in particular in a central section and/or in a section of the strongest curvature of the tension transmission device.
- the tension transmission device in particular the tension rod, and/or its first and/or second section can run in a curved manner at least in sections (possibly over the entire respective length).
- the damping device can be adjustable and/or deactivated with regard to its damping properties. For example, a spring hardness of the damping device can be varied or a suspension can be bridged (and thus deactivated). Alternatively or additionally, the damping device is at least partially replaceable. In particular, when walking or skiing, the damping element can be undesirable due to different movement sequences than, for example, when running. In such a case, for example, it can then be advantageous to deactivate the damping device. This can be done, for example, by bridging one of the two connecting devices (e.g. with a rigid element) so that rotation is prevented.
- the tension transmission device is preferably collapsible.
- the tension transmission device can be designed such that it is rotatably mounted in the area of at least one connection device (in particular the first and/or second connection device) such that it can be folded up in order to compress it in length. This can be helpful, for example, for transport or stowage.
- the first and/or second section can be pivoted relative to one another by preferably a maximum of 45°, more preferably a maximum of 25°, and/or at least 2°, preferably at least 5°.
- This may apply to any condition of the traction transmission device (tie rod) as long as it is intact (i.e. not destroyed). If necessary, however, it is also possible to allow further pivoting (for example beyond 45°) in a non-use state (for example storage state).
- a system comprising a traction transmission device, in particular a traction rod, as explained above, and i) a towing harness and/or a vehicle or at least its trailer hitch, with the towing harness or the vehicle or at least its trailer hitch being detachable or non-detachable , preferably relatively movable (particularly relatively pivotable), can be or is connected to the traction transmission device and/or ii) a child trailer, the child trailer being detachably or non-detachably, preferably relatively movable (particularly relatively pivotable), connectable or connected to the traction transmission device.
- the tension transmission device can be connected (possibly fixed) to a tension harness at one end.
- the traction transmission device can have a connection element for connecting the traction transmission device to a traction harness or another element that enables power to be transmitted from a person pulling to the traction transmission device.
- the traction transmission device can be connected (possibly fixed) to another element, such as a cabin or an axle of the child trailer.
- the train transmission device have a coupling element for coupling to another element of the child trailer.
- the child trailer preferably has at least one ground contact element, for example two (possibly exactly two) ground contact elements.
- the at least one ground contact element is preferably a wheel. Alternatively, however, a runner (or a ski) is also possible.
- the child trailer can be designed as a rickshaw.
- the child trailer can be configured in such a way that it can be pulled by human power, in particular by running, walking and/or by a vehicle, in particular a bicycle.
- the child trailer can weigh less than 50 kg and/or more than 5 kg.
- the above object is also achieved by a method for preparing (or producing) the above system, wherein in case i) the towing harness or the vehicle or at least its trailer hitch is detachably or non-detachably, preferably relatively movable, connected to the traction transmission device and/or in case ii) the child trailer is detachably or non-detachably connected, preferably relatively movable, to the traction transmission device.
- Further developments of the method result from the description of the traction transmission device above and/or below, with purpose information and/or functional features being able to be implemented as specific method steps.
