Description

The invention relates to a Modellfluggleiter, in particular skid.

Model aircraft ladders known in the art include skimmers and skid gliders.

The US 4,915,664 A describes a skipper having a hook to which a sling can be hung to accelerate the skipper. The hook is slidably mounted in the hull of the skipper. If the hook is acted upon by an acceleration force, it moves backwards and causes the wings (or wing tips) to be pivoted backwards. This should be reduced in the starting phase, the air resistance, so that the skipper can be thrown as high as possible in the air. If the speed of the skipper decreases and thus the air resistance decreases, the restoring force of a rubber band can overcome the air resistance, so that the wings of the skipper swivel back to their original position. In this position, the air resistance is higher, but the skipper has better sliding properties. It is considered disadvantageous that the return strap must be tuned very precisely to the geometry of the skipper, which determines the air resistance and thus the air resistance force. Overall, the construction according to this prior art is perceived as complex and prone to failure.

It is therefore the object of the present invention to propose a model aircraft ladder, in particular a skid, which is easy to manufacture and works reliably.

This object is achieved by a model vehicle ladder, in particular skid glider, according to claim 1.

In particular, the object is achieved by a Modellfluggleiter, in particular skid from, with a hull and at least one pivotable and / or tiltable wing, wherein a Flügelverstelleinrichtung is provided to the wings against a restoring force of at least one return means from a basic position to a start position at wherein the wings are pivoted or tilted by a predetermined angle relative to the basic position, wherein the return means are designed to transfer the model of the coach after starting again in the basic position, wherein the skid is at least partially formed of particle foam.

A core idea of the invention is to design (at least partially) the model vehicle ladder with pivotable or tiltable wings made of particle foam. In the prior art (see. US 4,915,664A ) hard plastic parts have been used in such model aircraft ladders with pivoting wings usually. Only with regard to the wings (but not at the connecting portion with the fuselage) is addressed that these are made of foam (ie not made of particle foam). Furthermore, it is mentioned in terms of a functionally insignificant bottom part, that this can be made of foam (but not of particle foam). The remaining parts, in particular those which allow the pivoting, are usually made of hard plastic and the like in the prior art. A (even partial) training of particle foam has not yet been proposed. The inventors have now recognized that it is quite possible to make the model vehicle ladder to a large extent (or completely, apart from possibly adhesive parts and the like) from particle foam. Surprisingly, it has been possible to develop model aircraft ladders which, with a constructively low outlay, realize the pivoting functions as already proposed in the prior art. In retrospect, it has been shown that the particle foam is particularly well suited due to its tough elastic behavior, to be used in a model co-driver, which has pivotable wings. Furthermore, it was recognized that particle foam over (conventional) foam is characterized in that it (almost) can be adjusted arbitrarily, especially in terms of elasticity, density and resistance. In particular (in contrast to conventional foam), it is possible to design different volume sections in terms of their elasticity and / or density differently within the model aircraft ladder. For example, where needed, the particulate foam can be adjusted so that the elasticity is high (for example, when a high restoring force is desired). Where less of a supporting function is required, the particulate foam may be formed in a particular volume portion of low density. This can reduce the weight.

The statement "made of particle foam" is intended to mean that the model of the vehicle ladder is (essentially) formed of particle foam, for example at least 50% by weight or at least 80% by weight or vol% of the model aircraft ladder made of particle foam. The model coaster may also be made entirely of particulate foam (possibly apart from connectors such as rivets and / or a model cockpit or the like).

Preferably, the return means comprise at least one section of particle foam, which is compressed or stretched at least in the starting position.

An essential idea of this development is that at least one section made of particle foam is provided in such a way that it influences the return, in particular after the start of the model aircraft ladder, the pivoted or tilted wing is returned to its basic or sliding position or contributes thereto. In principle, the necessary restoring force can be provided exclusively by the particle foam sections. However, it is also possible to provide further return means, such as springs or the like. In any case, a time-delayed provision is achieved in a simple manner by the at least one particle foam section, taking advantage of the fact that the particle foam (for example, relative to a rubber band or a spring) returns comparatively slowly to its original (relaxed) state. A delayed provision is therefore not (or not to the same extent) as in the US 4,915,664 A , inevitably associated with a fine vote between the restoring force of a rubber band and the outer geometry of the model of a passenger aircraft.

Here and below should be understood by a "pivoting" a rotation about a vertical axis of the fuselage. By "tilting" is meant a rotation about a transverse axis of the fuselage, which in turn is perpendicular to a longitudinal axis of the fuselage. In a "pivoting" thus moves a distal end of the corresponding wing to the rear, with the proximal end remains on the trunk. In a "tilt," the leading edge of each wing moves upward while the trailing edge moves down (or vice versa).

According to a further development, which is however also described and claimed as an independent aspect, the above object is achieved by a model coaster, in particular skid, preferably made of particle foam, wherein the Modellfluggleiter has at least one pivotable wing, wherein a Flügelverstelleinrichtung is provided to the wings against a Restoring force at least one return means from a basic position to a starting position in which the wings are pivoted to transfer, wherein the Flügelverstelleinrichtung is formed such that the wing is tilted by a predetermined tilt angle when it is pivoted.

A key idea of this solution is that with a pivoting of the wing at the same time a tilting is realized. This can be achieved for example by an inclination of a rotation axis or by a guide (slotted guide) at the proximal end of the wing.

Overall, an adaptation to the different conditions that prevail at the start on the one hand and in the sliding phase on the other hand is achieved with simple means. In the starting phase, the tilt angle can be comparatively low (for example, between -1 and 1 °). As a result, the air resistance of the wing is rather low. In the sliding phase, the tilt angle can then be greater (for example, 1 °, in particular 1 to 3 °). As a result, the model glider (due to increased buoyancy) can slide for a particularly long time without losing much height. At this point it should be made clear that a positive tilt angle means that the leading edge of the corresponding wing is higher than the trailing edge. A negative tilt angle means that the leading edge is within the trailing edge.

In a specific development, at least one particle foam section is twisted at least in the starting position. The twisted particle foam portion is thus under a torsional stress and acts as a torsion spring. This makes it easy to restore the basic or sliding position.

At least one particle foam section of the restoring means may be provided at a proximal end of a wing, in particular this cover, wherein preferably the entire wing is made of particle foam. Alternatively or additionally, at least one particle foam section of the return means can be provided on a front edge of a wing and / or on a stop section of the fuselage, which preferably faces the front edge of the wing, in particular, at least in the start position, is in contact therewith. By such measures, a (time-delayed) restoring force can be realized particularly easily.

In a specific embodiment, at least one particle foam section of a wing is in frictional contact with at least one body section in a predetermined position of the wing, in particular the start position. Alternatively or additionally, at least one compressed particle foam section of the hull, in a predetermined position of the wing, in particular in the start position, be in frictional contact with at least one wing section, so that the compressed particle foam section counteracts a provision. Although such particle foam sections do not promote the provision in the sense that a restoring force is provided; they nevertheless influence the provision, in that Due to the compression, a frictional force is generated. This also leads to a time delay, which has a positive effect on the flight behavior of the model of a passenger aircraft. In principle, it should be made clear at this point that the particle foam section of the restoring means can either itself provide a restoring force (which is preferred) or only influence it, by reducing the restoring force of another restoring means.

Preferably, the at least one return means comprises at least one spring, in particular metal spring, preferably helical spring. It is particularly preferred if the spring forms an operative connection between two opposing wings. By means of such a spring, it is possible (possibly parallel to the acting particle foam sections of the return means) to allow the model aircraft ladder to be returned to its basic or sliding position.

In a preferred embodiment, at least one wing adjustment device for pivoting or tilting a wing comprises at least one film hinge, wherein preferably at least one film hinge is tensioned in a predetermined pivoting position, in particular the starting position. Such film hinges are easy to manufacture. If the film hinge is provided as a tensioning device (or designed and arranged), then with only one element, both an attachment of the wing and a movement of the wing, as well as a restoring force can be realized. This significantly reduces the cost of producing the model aircraft ladder.

For throwing or accelerating the model of the aircraft ladder, in particular skid, a gripping device, such as a gripping plate and / or a gripping projection and / or hooks may be provided to start the skid manually (or possibly via a catapult device). An acceleration force acting on the gripping device preferably causes a pivoting or tilting of the wings. Further preferably, the gripping device is made of plastic, in particular as a plastic injection molded part, preferably made of particle foam. As a result, on the one hand the feel of the gripping device is improved, on the other hand weight can be saved. Overall, the operation of the model aircraft ladder is considerably simplified with only one measure.

Alternatively or additionally (preferably additionally), a (further) gripping device, for example gripping plate and / or gripping projection and / or hook, may be provided, which is rigid relative to the fuselage of the centrifugal glider. In particular, when this (rigid) gripping device is provided next to the (first, movable) gripping device, the play value is again increased significantly. For example, it is possible that by using the (rigid) gripping device an alternative flight behavior, for example a looping, is achieved. If, however, the (movable) gripping device is used, the skid glider can be thrown high into the air and then slide for a comparatively long time.

In an alternative embodiment, a corner portion of a wing may engage in a recess on the fuselage. Alternatively or additionally, a corner section on the hull engage in a recess on the wing. As a result, on the one hand (at least partially) a connection between the wing and the fuselage can be made. On the other hand, the corner portion rotates in the associated recess in a pivoting of the wing. As a result, a torsional stress is generated, which (as soon as no more pivoting force acts or still a little gravity) returns the wing in its basic or sliding position. In a further alternative, the wing may be integrally transitioned into a fuselage component; the wing should thus form a continuous, one-piece component (preferably made of particle foam), at least with a section of the fuselage. Due to the elasticity of the particle foam, pivoting is still possible and can be realized (safely) with structurally simple means.

As far as in the present invention of particle foam is mentioned, in particular (expanded) polypropylene can at least partially be used.

In a particularly preferred embodiment, the entire Modellfluggleiter, in particular skid, made of particle foam (possibly apart from gluing and / or film hinges and / or adhesive films and the like). Such a model passenger, especially skid, is particularly easy. For example, the weight may be less than 40 grams, or even less than 35 grams (especially when expanded polypropylene, EPP is used). The necessary restoring effect can be provided exclusively by the particle foam used. It can thus be dispensed with rubber bands or springs or other plastic particles. Overall, costs can be saved in the production.

The gripping device is preferably connected via at least one particle foam part and / or a plastic (film) part with one or both wings.

It is particularly preferred if the particle foam part is (approximately) V-shaped and the tip of the "V" with the gripping device is connected and the ends of the "V", each with a proximal end of the wing. Also, this can be further weight saved. Furthermore, such connecting parts can be manufactured at comparatively low cost.

A pivoting angle between the transverse axis of at least one steering wing and the longitudinal axis of the fuselage can be varied between a predetermined maximum angle (for example 110 ° or 90 ° or 80 °) and a predetermined minimum angle (for example 0 ° or 10 ° or 30 ° or 45 °). Alternatively or additionally, a tilt angle (adjustment angle difference, EWD) between the longitudinal axis of at least one wing and the longitudinal axis of the fuselage can be set between a predetermined maximum angle (of, for example, 7 ° or 5 ° or 2 °) and a predetermined minimum angle (of, for example, 2 ° or 0 ° or. 1 °) can be varied. As a longitudinal axis of the wing, the chord of the wing can be understood. As with the fuselage, the longitudinal axis of the wing is parallel to the incoming air (during flight). Preferably, in the start position, the minimum angle (of, for example, 0 °) and in the sliding position, the maximum angle (of, for example, 2 °) is set (automatically). As a result, the air resistance during the starting phase can be reduced in a simple manner and sufficient buoyancy is made possible during the sliding phase. As a result, the flight behavior of the model aircraft ladder is improved with a simple structural measure.

At least one wing and the fuselage (preferably the entire model passenger ladder) may be connected via a plug connection. This reduces the manufacturing costs. For example, each three superimposed parts can be zusammenklippbar (for example, a bottom part, a wing and a cover part).

In a preferred embodiment, the return means may comprise a damping element for delaying and / or reducing the restoring force. An additional damping element can further improve the delay in the return of the wings, which increases the efficiency of flight.

In order to effect a tilt by pivoting, an inclined pivot axis can be provided. An inclined pivot axis is to be understood as a pivot axis which is not oriented perpendicular to the longitudinal axis of the wing (and, for example, has an angle of> 1 ° or> 2 ° or> 5 ° with respect to the vertical). Alternatively, a tilting or pivoting can be achieved in that a proximal end of the wing is guided in a slot, which extends in such a (bow) shape that also results in a tilting when moving the proximal end due to the pivoting.

In preferred embodiments, the model flight conductor may have at least two volume sections which differ in terms of their elasticity (their modulus of elasticity) and / or in terms of their density and / or in terms of their stability (or hardness). For example, portions of the wing and / or fuselage may be formed adjacent to a contact area between wing and fuselage having higher elasticity and / or higher density and / or higher hardness (resistance) than portions farther from the connection between fuselage and wings (e.g. distal ends of the wings and / or an underbody and / or cover element of the fuselage). In general, those particle foam sections which form part of the return means can be formed with a higher modulus of elasticity and / or a higher density and / or a higher resistance force. Overall, with high functionality (pivoting or return) a low total weight with low design effort is achieved. Essentially, a single measure can therefore take account of the most important criteria (high functionality and cost savings in production).

In a specific embodiment, at least two volume sections (and / or surface sections) of the model passenger ladder may also differ in terms of their color. This can also be realized particularly easily with little effort by the use of particle foam. Optionally, more than three colors or a plurality of colors can be easily realized.

In principle, it is conceivable to produce the model passenger ladder "in one shot". This means that the entire model flight ladder can (essentially) be manufactured as a continuous particle foam part. The particles of the particle foam can be bonded together (sintered) in one (single) production step. The manufacturing costs are thereby further reduced.

The model vehicle ladder, in particular skid glider, may have a model cockpit which does not have to be formed of particle foam, for example of plastic (transparent plastic) and / or glass.

The model passenger ladder is preferably designed as a skid slide. The term In the present case, however, a model glider should preferably also include gliders and / or skippers.

Further embodiments emerge from the subclaims.

The invention will be described in terms of further features and advantages based on embodiments, which are explained in more detail with reference to the drawings. Hereby show:

In the following description, the same reference numerals are used for the same and like parts.

1 shows a first embodiment of a centrifugal glider in a view from below.

The bug is with the reference number 10 characterized. The tail is with the reference number 11 characterized. The skid has a hull 14 as well as a first wing 12 and one, the first wing 12 opposite, second wing 13 on. The wings 12 . 13 are on the one hand over the hull 14 and on the other hand via an accelerator 15 connected with each other. The accelerator 15 serves at the same time the pivoting (and possibly tilting) of the wings 12 . 13 (see below). The accelerator 15 has (approximately) a V-shaped or Y-shaped outline and comprises a (horizontal) base plate 16 , a (vertical) gripping plate 17 and a first leg 18 and a second leg 19 , About the gripping plate 17 (see also 3 and 4 ) the skid can be accelerated manually.

The base plate 16 connects proximal ends 20 . 21 the thigh 18 . 19 together. Distal ends 22 . 23 the thigh 18 . 19 are with the wings 12 . 13 connected.

The connection of the proximal ends 20 . 21 with the base plate 16 For example, may be integrally formed, so that the base plate 17 and the thighs 18 . 19 form a one-piece component. The connection between the distal ends 22 . 23 and the wings 12 . 13 can be realized via an adhesive and / or (adhesive) film elements (not shown in the figures) or be integral.

Specifically, the distal ends 22 . 23 the thigh 18 . 19 in rear sections 24 . 25 from proximal ends 26 . 27 the wing 12 . 13 arranged. The distal ends 22 . 23 are thus adjacent to the rear edges 28 . 29 the wing 12 . 13 ,

corner areas 30 . 31 the wing 12 . 13 between the proximal ends 26 . 27 and leading edges 32 . 33 the wing 12 . 13 are in Eckausnehmungen 34 . 35 arranged. The first corner recess 34 is a fixation bar 36 assigned, in turn, the first wing 12 assigned. The second corner recess 35 is associated with a second fixing bar, which is the second wing 13 assigned. The fixation bars 36 . 37 extend to a margin 38 of the hull 14 in a front area.

The wings 12 . 13 are adjacent to the corner areas 30 . 31 in the corner holes 34 . 35 are arranged, with film hinges 40 . 41 provided the wings 12 . 13 with the fixing strips 36 . 37 connect.

Now acts an acceleration force F (see arrow 42 in 1 ) on the gripping plate 17 , this moves forward (see 2 ). The gripping plate 17 is with the base plate 16 connected (possibly integrally formed with this). About the base plate 16 and the thighs 18 . 19 become the back sections 24 . 25 the proximal ends 26 . 27 the wing 12 . 13 forward towards the bow 10 drawn. At the same time, front sections encounter 43 . 44 the proximal ends 26 . 27 or the corner areas 30 . 31 against the fixing strips 36 . 37 facing the hull 14 are fixed. This will prevent the front sections 43 . 44 to be moved forward. Overall, through this training achieved that the wings 12 . 13 or distal ends 45 . 46 to the rear in the direction of the stern 11 be panned. The accelerator 15 is thus (also) a pivoting device.

The entire skid according to the first embodiment (apart from the film hinges 40 . 41 ) is made of particle foam (EPP) (if necessary, further adhesive components, in particular adhesive film strips or adhesives may be present).

The film hinges 40 . 41 are in the position according to 2 stretched at least partially and thus contribute to a restoring force R, the antiparallel to the force F from 1 acts and a provision in the position according to 1 causes (as soon as there is no acceleration force or falls below a certain threshold). The restoring force R is indicated by an arrow 47 (please refer 2 ). At this point, it should be made clear that there are a large number of restoring forces due to a wide variety of components and that the restoring force R is only the sum of these forces, which is ultimately the return of the wings 12 . 13 in the position according to 1 causes.

To the restoring force R continues to bear the accelerator 15 (or pivoting device 15 ), which are in position according to 2 is under tension, so that an elastic restoring force is generated. Furthermore, in contact areas 48 . 49 on which the wings 12 . 13 with the fixing strips 36 . 37 in contact with the contact areas 48 . 49 compressed adjacent sections. Due to this compression, a restoring force component also arises. In a similar way are also contact areas 50 . 51 between the thighs 18 . 19 and to these adjacent sections of the wings 12 . 13 (partially compressed, partially stretched and overall elastically twisted).

Overall, the restoring force R is achieved exclusively by elastic restoring forces of the various particle foam components (apart from the cooperation of the film hinges 40 . 41 ; However, these can also be omitted in an alternative embodiment or be designed and arranged so that these also in the position according to 2 do not generate restoring force or are not live).

Altogether one recognizes that the position according to 2 reduces the inflow of the centrifugal glider. At the same time, it can be seen that this position is achieved by providing an acceleration force F; the position according to 2 is taken at and shortly after the start (eg for at least 0.5 s or 2 s).

After the start, one of the wings acts on the one hand 12 . 13 on the other hand, the restoring force R, which has been described above, acts on the rear towards the rear. With decreasing speed of the skid, the force also decreases due to the applied flow. At a predetermined speed, the restoring force R overcomes the force due to the applied flow, so that the wings 12 . 13 in the position according to 1 be moved back. Due to the slow-elastic mode of action of the particle foam, this takes place comparatively slowly.

3 shows the position according to 1 in a side view. In this (relaxed) position, in which no acceleration force (or only a small acceleration force) on the gripping plate 17 acts, points the wing 13 a tilting (of in this case 2 °) on. The back edge 29 of the recovered wing 13 is thus below the front edge 33 of the recovered wing 13 , The indicated 2 ° refer to the horizontal (in 3 , based on the direction of the incoming air).

In 4 is the position according to 2 shown in a side view. Here is a smaller tilt angle is formed (of concrete 0 °), which means that the front edge 33 and the back edge 29 are arranged at the same height or horizontally or along a straight line which is parallel to the incoming air. This also reduces the flow resistance during the climb phase of the skid, in which the skid is at a high speed. The skid can thus reach a great height before the wings in the position according to 1 and 3 to return. Overall, both the achievable altitude and the achievable flight distance can be significantly increased (and with simple design means).

As in the 1 to 4 To recognize, the skimmer is modeled on an aircraft. However, it is also conceivable (this also applies to the following embodiments) that the skid glider takes the form of a bird of prey or dragon or other slippery toy.

5 shows a second embodiment of the centrifugal slide in a side view. In this embodiment, the hull is made 14 from a bottom part 52 (Bottom plate) and a shell 53 (Top plate); additional elements can be provided if necessary. The bottom part 52 has a (flat) underside 54 and a (plane) top 55 on. The top 55 is (in sections) with a base 56 of the top 53 connected. The top 53 also has a top 57 on. In a front area of the top 57 is a cockpit 58 . in a rear area a rear wing 59 intended. Furthermore, a wing 13 to recognize. The wing 13 is partially in a recess 60 on the bottom 56 of the top 53 arranged. This may cause the wing 13 or its proximal end within the trunk 14 move backwards (for example due to a pivoting movement).

In 6 is the embodiment according to 5 shown in a view from below. At the stern 11 is a (horizontal) rear wing 61 intended. The in 5 recognizable rear wing 59 is vertically aligned.

In 6 it can be seen that the wings 12 . 13 opposite the fuselage 14 over swivel axes 62 . 63 are pivotable. The pivot axes 62 . 63 may for example be formed by pin (or rivet) shaped elements, which may also be the attachment of the wing 12 . 13 serve.

Basically, lower part can 52 and top 53 and possibly other plates (not shown) and the wings 12 . 13 be connected to each other via pins or rivets and thus form, for example, a plug connection. An adhesive bond may be provided, but preferably the connection is achieved exclusively via a (latching) plug connection.

7 shows the embodiment according to 5 . 6 but for better illustration, the bottom plate 52 was omitted. The view according to 7 thus corresponds to a schematic view from below without bottom plate 52 ,

An accelerator 15 comprises (similar to the first embodiment) a base plate 16 and a gripping plate 17 (see also 5 ). The base plate 16 is about film hinges 64 . 65 with corner areas 30 . 31 between leading edges 32 . 33 and proximal ends 26 . 27 the wing 12 . 13 arranged.

The leading edges 32 . 33 the wing 12 . 13 are still over a coil spring 66 connected with each other.

In 7 are still recesses 67 . 68 and 69 to see. The recess 67 is as a guide rail for the base plate 16 provided and trained so that these move towards the bow 10 to be led. This simplifies the acceleration of the skid. The recesses 68 . 69 are provided to the proximal ends 26 . 27 the wing 12 . 13 with a pivoting of these ends towards the bow 10 take. Now acts on the gripping plate 17 an acceleration force F, the gripping plate moves 17 in the recess (rail) 67 in the direction of the bow 10 (please refer 8th ). This will make the wings 12 . 13 or their distal ends 45 . 46 pivoted backwards. The proximal ends 26 . 27 at the same time pivot (forward) into the recesses 68 . 69 into it. This is the coil spring 66 curious; excited.

A restoring force R therefore acts due to the tensioned coil spring 66 and additionally due to a press contact between the leading edges 32 . 33 and jetties 70 . 71 that the recesses 68 . 69 limit to the outside. The contact area is indicated by the reference numbers 72 . 73 marked (see 8th ). Both the bars 70 . 71 as well as the wings 12 . 13 consist of foam (particle foam), thus in the position according to 8th is compressed, resulting in a restoring force. The restoring force of the spring 66 and the press contacts 72 . 73 Overall, when falling below a certain force of the incoming air or below a certain acceleration force (or a sum of acceleration force and force of the incoming air), the wings 12 . 13 in the position according to 7 (automatically) be returned. Due to the slow-elastic behavior of the particle foam parts 70 . 71 . 12 . 13 , this provision takes place with a comparatively high time delay. Overall, thus a high altitude can be achieved with a simple design effort.

In the in 5 shown basic position also show the wings 12 . 13 According to the second embodiment, a tilt angle of (about) 2 °. About an inclination of the pivot axes 62 . 63 (or via a slotted guide in the area of the proximal ends 26 . 27 the wing 12 . 13 ) can result in a tilting a tilt, so in a pivoted position according to 8th for example, the tilt angle is 0 °. In general, the tilt angle in the climbing phase (according to 8th ) be smaller than in the sliding phase (according to 7 ).

Preferably, between the fuselage 14 and the wings 12 . 13 at least partially made a press contact, in particular between the upper part 53 and wings 12 . 13 or lower part 52 and wings 12 . 13 so that a frictional force (due to the compression of the particle foam parts) and a delayed return of the wings 12 . 13 results. Overall, the second embodiment can also be made (almost) completely of particle foam (possibly with the exception of pivot axes or pivot pins and / or adhesive films and / or film hinges and / or adhesives).

It should be noted at this point that all parts described above, taken alone and in any combination, especially the in the drawings illustrated details are claimed as essential to the invention.

Variations thereof are familiar to the person skilled in the art.
