Description
The present invention relates to be used to protect the device of the land vehicles against impacting stones of constrained by rail.The invention particularly relates to the protection of railroad vehicle in the high-speed range of the above speed of 250km/h.
Hit even only speak of stone in specification sheets and claims, its implication has also comprised the similar effect that impact effect produced by other particle, for example the similar effect by causing on the travel or along the mush ice or the loosening thing of travel.
The track of high-speed train is often pressed the casting concrete technique construction of no rubble ballast aggregate now.The danger that hit by stone is very little.But,, there is the track of rubble ballast aggregate also to be used for high-speed train for example in Spain, France, Italy in some country.Therefore, especially in the traveling gear zone of train and other vehicle and the device below the bottom bear more stone strike.These devices for example are current transformers, voltage transformer and other installing component.Therefore may be damaged until operating troubles and accident as time passes under the situation of fender guard not having.
The possibility that a kind of anti-stone hits is; settle the entity baffle plate in the object front that will protect; the surface of baffle plate is orientated as far as possible like this, makes stone on the bump favour the surface normal bump and to for the hazard free direction deflection of other parts of this railroad vehicle.
The shortcoming of this fender guard is that weight is big, and this is owing to high requirement of strength produces, and this requirement of strength is caused by the kinetic energy of being intercepted and captured object.Therefore, mainly be train but comprise that also other car should be suitable for two travel direction, therefore must settle fender guard in the both sides of the object that will protect.The element of this outer baffle can damage as time passes, thereby or must change, perhaps can only bear its defencive function limitedly.Latter event even may cause fender guard itself to become dangerous.
In addition disadvantageously, this baffle plate stops the watching of covered parts, must be disassembled and then load onto in the vehicle inspection of routine.
In low-speed range, also know the fender guard that uses thin plate, panel grid or constitute based on elastic body or fibre reinforced materials.But these devices are not suitable for high-speed range.
Task of the present invention is; provide a kind of open-air driving vehicle that is used to protect constrained by rail to avoid stone to hit and the device of similar impact effect, this device makes the power that is produced when stone strikes on the object of protection reduce as much as possible under the little situation of conducting oneself with dignity.
A basic design of the present invention is that fender guard is flexibly implemented in the subregion at least.If stone or other object strikes are on the part of this fender guard or this fender guard, this bump causes elastic deformation, reduces thereby cause maximum force to be compared with rigid mount.(especially under the very high situation of bump particle momentum) additional plastic deformation that isolated screen occurs is not got rid of in the appearance of elastic deformation.
In first test of the present invention,, clash into from the known physical protection element of prior art with simulated stone with partickle bombardment one entity steel element (for example steel plate).These tests show that the steel element must be counted cm thick, so that enough protections are provided when high moving velocity.
Therefore, at first based on the basic thought of isolated screen elastic construction metal sheet is equipped with rubber element, rubber surface bears stone and hits.But show that the high like this energy of point-like effect is transformed into heat in short-term in elastomeric material under up to the velocity of impact of 350km/h, portion is overheated and lose its elastic behavior within it to make elastomeric material.Show that in addition the power that acts on the bracing or strutting arrangement of fender guard reduces unsatisfactorily.
Therefore propose, this device has an isolated screen, this isolated screen extends on the face of the effect of playing anti-stone strike barrier, and wherein a kind of material of this isolated screen and/or a structure have elasticity, so that the stone that strikes on the isolated screen causes the isolated screen elastic deformation.
The elastomeric isolation screen can be contained in the front of the object that will protect, especially can use knotwork and/or the fabric made from wire rod and/or rope (for example wire rod rope made from many single line materials) as the elastomeric isolation screen.The face that the top isolated screen of mentioning extends thereon is not the surface that is made of a kind of material in this example, but an imaginary or mathematical space face.
Knotwork or fabric are compared and can especially easily be implemented with the blocking capability that is reached.The common own elastically deformable of fabric in addition.This also is applicable to this situation: (being this situation in a preferred embodiment) wire rod and/or rope can extend resilient movement at least partly transverse to its length under the impact effect of estimating.
A kind of particularly preferred embodiment that can be used for the isolated screen in apparatus of the present invention is disclosed by CH 692 921 A5.This preferred implementation is described by Fig. 1 in the document, but wherein the fixing of wire rod knotwork mesh on the wire rod knotwork edge preferably differently implemented according to the present invention.This also will explain in the back in detail.But about wire rod knotwork itself fully referring to CH 692 921 A5, specifically in these areas: how constitute a wire rod knotwork and the nominal intensity of wire rod and the material of wire rod with different wire rods.Wire rod also can also then be knitted when making the wire rod knotwork mutually in scroll prebuckling, so that generation has the wire rod knotwork of the rule of approximate quadrangle mesh.
Preferred these wire rods are single-piece wire rods, and they no longer are made up of a plurality of single line materials.The wire rod that these wire rods also can preferably be made with high strength steel, they for example are used to make steel rope in other application scenario.For example use according to the DIN2078 standard and have 1000 to 2000N/mm
2Between the wire rod of nominal intensity.Nominal intensity is preferably greater than 1200N/mm
2, especially be preferably greater than 1600N/mm
2But also can use the spring wire that meets the DIN17223 standard.Wire thickness is 3mm, 4mm especially at least at least preferably.Thickness depends on the tensile strength of selected material and hope.If wish the speed up 350km/h of track restrained vehicle, be 1800N/mm for example then at tensile strength
2Shi Houdu is 4mm.
With different by the described wire rod knotwork of Fig. 1 of CH 692 921 A5, angle that knot is reached by forming on the mesh bight, that observation wire rod trend is changed in the knotwork plane also can have different values.For example be about 150 ° in a preferred embodiment, so that form 30 ° mesh interior angle.
As can seeing from Fig. 2 of CH 692 921 A5, the trend of each wire rod is promptly extended in first plane that is parallel to each other and second plane with before adjacent wire rod forms a knot and extend in different planes afterwards.These planes are spaced from each other.
In other words, wire rod or rope and adjacent wire rod or a plurality of knots of rope formation, wherein the trend of wire rod or rope is being extended in one first plane before the knot substantially, extends in one second plane substantially after this knot, wherein, first plane and second plane are parallel to each other.
According to the present invention, the distance on these two planes preferably is at least gauge or diameter of wire wire thickness in other words.This spacing is twice, especially at least three times of wire thickness at least in a particularly preferred embodiment.
Therefore form a kind of wire rod knotwork on the whole, it is not the formation thing on basic plane only, but has three-D volumes.This characteristic allows to compare with type with the intensity of use wire rod the elastic deformation of special high-amplitude.That is, can select very tension and thicker wire rod, this wire rod knotwork just allows than higher amplitude of deformation.
Test shows in addition, and stone or other grain breakage that this wire rod knotwork can make bump come up become less fragment.Even a part of fragment successfully passes this wire rod knotwork, owing to the reason of two aspects is impacted and also obviously reduced.On the one hand, the quality of the original particle of the mass ratio of fragment is little.Speed reduces when on the other hand, striking on the wire rod knotwork.The big I in space is selected like this between the wire rod, makes when the stone of the maximum possible that can not pass the space with wire rod mutual action bump and does not occur unacceptable damage during the expectation speed in maximum possible.
The wire rod knotwork is its ventilative property with another advantage tabular or that flaky material is compared.Therefore interfering aerodynamic effects and aeroacoustics effect have been avoided.Therefore the corresponding optimization of object aspect aerodynamics and aeroacoustics characteristic that will protect is not eliminated or only seldom eliminated to this isolated screen.
Another advantage of wire rod knotwork is that its size (size of the area of being crossed when being knotwork formation isolated screen) can be simply individually at required situation was next adaptive at that time.For example can the wire rod knotwork of being supplied be cut apart or diminish with less expense.This specific character especially makes can install this wire rod knotwork with rational expense afterwards on already present vehicle, because it can be installed with comparalive ease.This exterior line knotwork is than the easier replacing of the plate of entity.
If this elastomeric isolation screen has framework, maintain by the isolated screen part (for example wire rod knotwork) of this framework an elastic construction, then this framework can selectively shrink on the direction of estimating the stone strike pointedly.Can reach thus, the stone that strikes on the framework is not to act on the framework with its whole momentums, pulverizes in other words but be deflected and/or be broken.
Another conceives the structure that is bracing or strutting arrangement substantially the present invention, and by this bracing or strutting arrangement, isolated screen (identical with for example stiff isolated screen form) can be installed on another object by anti-stone with hitting.This another object for example can be object or other object that will protect.Bracing or strutting arrangement also can be called as holding device.According to the present invention, bracing or strutting arrangement preferably itself has elasticity.Can make the isolated screen frame part that may exist thus or the stone of the isolated screen of non-resilient structure is hit the power that acts on the object that will protect or act on this another object and reduce.
If the supported device of the isolated screen of elastic construction supports maintain in other words, then have additional advantage: the wearing and tearing of elastomeric isolation screen are owing to the elasticity of bracing or strutting arrangement reduces.
Preferably in resilient supporting unit, use at least one elastic element (especially at least one integral type element made from elastomeric material).
If stone or other particles hit are to isolated screen, this particle to the part of its momentum of major general passes to isolated screen.Thus, isolated screen or at least its part move, elastic element is subjected to pressing load thereby elastic deformation in this motion, until reaching the maximum distortion state.Because elasticity is (if other collision does not take place during this period or act on other external force) the anti-motion of beginning (motion with reverse motions direction) usually, to eliminate elastic deformation.The internal friction of elastic element causes vibration damping.
Preferred in addition, elastic element is structure and arranging like this, makes it in sense of motion commutation back be reversed to (finishing in this first vibration semiperiod of moment) back also elastic deformation and so further damped vibration in the back to back vibration semiperiod in the dead position at original (before the stone effect) place.That is, same elastic element makes vibration damping during whole period of vibration in this scheme.Preferred especially at this, a part of pressurized load of this elastic element in each vibration semiperiod, and another part off-load of this elastic element and/or be subjected to pulling load.
Alternatively can in resilient supporting unit, use two elastic elements, wherein directly when stone clashes at first first elastic element (may except that prestress additionally) be subjected to pulling load and elastic deformation, the off-load of first elastic element wherein, takes place again after reaching the maximum distortion amplitude.Usually after the equilibrium point that exists before reaching the stone bump, second elastic element pressurized load is until reaching maximum distortion amplitude etc. again.
This elastic element or two elastic elements can for example respectively have a through hole in a specific embodiment, a microscler extending element, and for example a bar, a sleeve and/or a screw rod pass this through hole and extend.In (on sense of motion, seeing) central region of elastic element, be supported with a retaining element, on the object that elastic element is fixed on the isolated screen by this retaining element or another maintains isolated screen (maintenance matrix).(second kind of situation) retaining element can be provided with through hole between two elastic elements and also in the embodiment with two elastic elements.
One end of microscler extending element (directly or for example passing through framework indirectly) is connected with isolated screen.Retaining element is connected with the object that will protect or another object, and this device is supported on this object.Alternatively, retaining element can be connected with isolated screen and microscler extending element is connected with this object.A plurality of these class bracing or strutting arrangements preferably are set, and they can be supported on the same or different objects, so that support isolated screen.The free end of microscler extending element for example is provided with a final element, one of this elastic element (first kind of situation) or two elastic elements (second kind of situation) was supported on this final element in the corresponding vibration semiperiod, and the regional pressurized that abuts on the final element of elastic element is loaded in this vibration semiperiod.Final element is preferred under second kind of situation installs like this, makes two elastic elements also be in when neutral position and press under the load that prestress is promptly arranged.
Bracing or strutting arrangement especially can have with the lower part:
-one microscler extending element, it at one end with the isolated screen that will support (situation a) or with one keeps matrix (situation b) to be connected maybe and can to connect,
-at least one has the elastic element of the portion of leaving a blank, and microscler extending element passes this portion of leaving a blank and extends,
-one retaining element, by it, the central region of this elastic element or two elastic elements is supported on and keeps on the matrix (situation a) or be supported on (situation b) on the isolated screen that will support,
-one final element, it is placed in the zone of second free end of microscler extending element, and a free end of at least one elastic element is supported on this final element in a free end of this elastic element or these elastic elements.
According to another design of the present invention, this design relates to the maintenance of wire rod knotwork and/or rope knotwork, and the edge of knotwork is maintained by (preferred rigidity) framework.This knotwork for example can be the knotwork with quadrangle periphery sideline.Correspondingly framework then is tetragonal framework, wherein adjoins mutually and is mutually permanently connected at each two section (connecting strap) of each bight upper frame.
At least one section of framework, preferred whole four sections or framework connecting strap have the structure of two-piece type in previous example, and a lower member and a upper-part wherein are set.The notion on bottom and top does not limit to be used prevailingly and not to mean that in fact upper-part must be in top in real work.The end in cooresponding connecting strap zone and/or the bending of wire rod or rope are positioned between upper-part and the lower member, and upper-part is individual to be interfixed with parts.At this, wire rod maybe can be clamped between upper-part and the parts or can be free movable.Preferably wire rod and/or rope can be free movable except the mesh bight between upper-part and lower member, and they are crooked or mutual the winding on the mesh bight.Upper-part and/or lower member can have the portion of leaving a blank for this reason, and their shape is corresponding to the knotwork type.
For the fixed mesh bight, microscler extending element, for example the pin or screw, can transverse to, especially extend perpendicular to the knotwork plane.Preferred upper-part and lower member interconnect by pin or screw and interfix.
In addition, will for example be used to protect the land vehicles against impacting stones of constrained by rail also to belong to the scope of the invention by the disclosed known wire rod knotwork of CH 692 921 A5.Especially at least one wire rod knotwork is fixed on this vehicle.
Hit protection in order to reach anti-stone, one for example is connected with vehicle according to the isolated screen of one of such scheme.This isolated screen then for example is arranged in the zone of the bottom of railroad vehicle, perhaps for example be fixed on the bogie truck the object of being installed or the device on.
According to another design of the present invention, isolated screen of the present invention can be used on the arbitrary configuration (preferably having resilient supporting unit) that is used for protecting the anti-stone strike of stationary object.Especially can protect railroad vehicle around avoid by by the railroad vehicle that crosses especially because of mechanical action and/or because the fluid dynamics effect winding particles hit of getting up.This isolated screen for example can be placed on the bridge and (fall to avoid particle), be placed in signalling set or other be used for the highway section operation or be used for the device of personal protection the zone (for example track and near the footway between).
Referring now to accompanying drawing embodiments of the invention are described.The feature that describes below can be individually or combination in any ground combined with previously described the present invention program.Each accompanying drawing illustrates:

The schematic cross section of the replacement embodiment of Fig. 9 bracing or strutting arrangement (the diagram plane comprises the longitudinal axis of elastic element 43).
Isolated screen 1a shown in Fig. 1,1b respectively have a framework 3a, ab.Isolated screen 1a, the knotwork of 1b do not describe in detail in Fig. 1.At framework 3a, the plane of white only can be seen in ab inside.Wire rod knotwork shown in Figure 8 for example constitutes isolated screen 1a, the protective surface of 1b respectively.This wire rod knotwork also will be described in detail.
Isolated screen 1a, 1b is by its framework 3a, and other device of ab and some is connected with the housing 5 of an inverter, also will explain these devices in detail by Fig. 2 and Fig. 3.In order to make isolated screen 1a, in the downward-sloping slightly orientation shown in 1b remains on, on housing 5, also be fixed with some additional adapter plate 6a to 6d, some retaining element 30a, 30b are connected with these adapter plates again.Also to explain these retaining elements in detail by Fig. 2.
Fig. 2 illustrates two isolated screen 1a, the back side of one of 1b.Can see, respectively be fixed with a fuel plate 32a to 32d at folding corner region on framework 3, preferably ground, turning is connected (for example welding or soldering) with two connecting straps in this bight of formation of framework 3 respectively.Can see in addition, among four bracing or strutting arrangement 33a to 33d is housed on each fuel plate 32 altogether.At this, two upper support device 33a only, the retaining element 30a of 33b, 30b and two lower support device 33c, the retaining element 30c of 33d, 30d constructs differently.Construct in an identical manner at these bracing or strutting arrangements of others.
In order to describe the structure of bracing or strutting arrangement in detail, below with reference to Fig. 3.This section by one of two upper support devices also illustrates framework 3, definitely says the connecting strap 3-1 that its top is shown, and this connecting strap is two-piece construction in this embodiment.Also to explain in detail for this two-part construction.This connecting strap 3-1 is connected with fuel plate 32 (plate that for example is made of a steel), and this plate has a centre hole (for example tapped bore 41, one screw rods 42 are screwed in this tapped bore and are prevented from unexpected the back-out).Screw rod 42 (not shown in Figure 3, but referring to the replacement embodiment among Fig. 9) is determined the longitudinal axis of bracing or strutting arrangement and elastic element 43, and retaining element 30 can restrictedly be moved with respect to framework 3 along this longitudinal axis by the elastic behavior of elastic element 43.
Retaining element 30 has a through hole, and elastic element 43 passes this through hole and extends.In elastic element 43, insert at least one other retaining element, it in Fig. 3 in the zone shown in the upper and lower with label 101,102 marks.In this case zone 101,102 be subordinated to an integral type annular and/or flanged vulcanizate be incorporated into element in the elastic element 43.
The inside of the through hole of elastic element 43 this hole vertically on (equal elastic element 43 vertically) extend sleeve 40 (being metal hollow cylinder in the present embodiment), this sleeve is connected with a tabular final element 46 on a free end of elastic element 43.
Elastic element 43 has one (pref. cylindrical) base 44, and this base shrinks towards the nearer end of screw rod 42 respectively.But elastic element also can have the outline of other shape.This cylindrical sector 44 constitutes the shoulder of withdrawing on the longitudinal axis at through hole (wherein the trend that is dihedral in cross-sectional plane of outline in practice can rounding) in a side (right side among Fig. 3) under present case, is connected to a section 45 of contraction gradually on this shoulder.At the other end of elastic element 43, gradually the section 45 of Shou Suoing ' the end abut on the tabular final element 46.For example can the recline screw head of a screw of the outside of this external final element 46, this screw passes described through hole, elastic element 43 by this screw-driving on fuel plate 32 (by being screwed in the tapped bore 41, perhaps be screwed in the nut 49, this nut selectively or replace tapped bore 41 ground settings).
From diagram top and the bottom part, can see, not only fixed anchoring in elastic element 43 retaining element 102 and also retaining element 30 all have at least one hole 103,103 '.Insert these holes 103,103 ' in and the interconnective securely immobilising device of retaining element 30,101 or 30,102 (for example screw) is not shown.
Have retaining element 101,102 and the elastic element 43 of sleeve 40 and final element 46 can be by the title of Kabinenlager (article number 18.01.01-..NR) at auspicious CH-8134Adliswil, Soodstrasse 57, and Schwab Schwingungstechnik AG company buys.
The alternative of bracing or strutting arrangement shown in Figure 9.Only explain difference below with the embodiment of describing by Fig. 3.3 and Fig. 9 in, identical labelled notation identical or at the identical or similar part of function aspects.
Bracing or strutting arrangement according to Fig. 9 replaces an elastic element 43 to have two elastic element 43a, 43b, and they are arranged in the vertical.Retaining element 30 is with two elastic element 43a, and 43b is separated from each other.Screw rod 42 passes two elastic element 43a, and through hole of each among the 43b and in the retaining element 30 extends.
Two elastic elements 43 preferably have columniform base 44, and this base shrinks towards the nearer end of screw rod 42 respectively.But elastic element also can have the outline of other shape.This cylindrical sector 44 constitutes a shoulder of withdrawing on the direction of screw rod 42 under present case, is connected to the section 45 that shrinks gradually on this shoulder.The end face of this section that shrinks gradually 45 abuts on the fuel plate 42 or for another elastic element 43b and abuts on the final element 46, and this final element 46 is threaded on the free end of screw rod 42 and is prevented from accidental release by black nut 47 in the present embodiment.
The stone or other object that strike on isolated screen 1a or the 1b have momentum, and the largest component of this momentum is often referred to the direction perpendicular to the isolated screen plane.Therefore this direction component also extends on the direction of screw rod 42 at least.Therefore, because two elastic elements 43, this momentum is attenuated and lingeringly is delivered on the retaining element 30 from fuel plate 32.When stone clashed into, at first elastic element 43a was compressed, up to the peak excursion point of the distortion that reaches elastic element 43a.Then, another elastic element 43b half period of vibration farthest screw rod 42 vertically on shorten i.e. compression, but wherein because the damping force characteristics of elastic element 43 is should compression strong like that in half period of vibration before not.By correspondingly drawing final element 46, elastic element 43 is also prestrain of quilt in neutral position.Be glued on the adjacent part if elastic element 43 cures, then this prestrain also protecting component 43 therefore avoid being subjected to pulling load and split or rupture.
Again also to mention with reference to figure 2, with retaining element 30a, the L shaped position attitude difference of 30b, retaining element 30c, 30d are configured to U-shaped in cross-sectional plane.The structure of retaining element normally freely and depend on the installation situation of isolated screen.
Fig. 4 illustrates a preferred version of the framework of wire rod knotwork.Shown framework for example can be the framework 3a according to Fig. 1, one of 3b.Framework 51 two-piece construction shown in Fig. 4.Can see lower member, promptly with fuel plate 32a to the 32d bonded assembly spare that schematically illustrates.Also can see the tapped bore 41 in the fuel plate 32.Represent that by two parallel oblique lines framework 51 is not described with its whole size.Each connecting strap of framework 51 is a shape element and with label 3-1 (top among the figure), 3-2 (the right), 3-3 (bottom) and 3-4 (left side) mark.These connecting straps are fixedly connected to each other on the bight of framework 51.These connecting straps have the portion's of leaving a blank groove in other words in addition, and they have different shapes according to the connecting strap difference.Groove in top and the connecting strap bottom extend on the whole length dimension of two connecting straps corresponding to the structure flexagon ground of the fabric that will be kept by this framework 51.These grooves label 53a and 53b mark.Can see that the groove 53a of flexagon, 53b not only have the opening 54 towards framework 51 inboards, and have opening 55, but wherein toward the outer side opening 55 not to exist towards this framework outside.On the contrary, the opening 54 towards the inboard must exist, so that allow the wire rod or the rope of knotwork to enter and go out.If knotwork for example shown in Figure 8 is maintained by framework 51, then 91 edges 92 of the knotwork shown in the left side are arranged in the groove 53b of bottom connecting strap 3-3 in Fig. 8.Among the groove 53c of 93 on the left side connecting straps of top edge 3-4 of knotwork 91, wherein these grooves shown in cross-sectional plane in be trapezoidal.Groove 53d among the connecting strap 3-2 of the right also is trapezoidal configuration.
Because the description of Fig. 4 relates to the accompanying drawing of structure design graph type, can see a plurality of line of centerss, they intersect at the mid point in hole respectively.For example at each trapezoidal groove 53c, respectively there is a hole that is used to receive a microscler extending element (not shown) inside of 53d, some holes label 57 marks.When knotwork 91 is clamped, hole 57 or be placed in wherein microscler extending element and be positioned at mesh bight on this knotwork edge with about 30 ° of interior angles perpendicular to the diagram plane of Fig. 4, promptly cross as mentioned like that for example on the edge 93 of knotwork 91.
The corresponding hole 58 that has some to be used for microscler extending element on the inward flange of flexagon groove 53b and 53a again, when knotwork 91 was fixed, these holes were arranged in the zone in the mesh bight with about 150 ° of big blunt interior angles.In the zone in the bight of framework 51, the groove 53a of flexagon, 53b respectively carry out the transition to a trapezoidal groove 53c, among the 53d.
Schematically Fig. 5 illustrates, and this framework two-piece type ground (being the lower member 63 that is in following upper-part 62 in the drawings and illustrates in the above here) constitutes.Can see the opening 55 in two outsides of groove 53, they both also constituted in lower member 63 in upper-part 62.Can see one of them fuel plate 32 in addition.But the tapped through hole 41 that passes this element 32 is not arranged in this diagram plane, but is positioned at its back, as from appreciable Fig. 4.In this fuel plate 32 and lower member 63 welding, as appreciable such on weld seam 64,65.It for example is the folding corner region towards connecting strap 3-3 of connecting strap 3-2.
Fig. 6 illustrates a different slightly embodiment of the framework 71 that also is two-piece type, has the upper-part 74 and the lower member 73 of a connecting strap.With the same outside that this framework is shown among Fig. 5.Also can see the opening of the groove that constitutes in this framework, they use label 65 marks here.Appreciable ellipse representation can be by the approximate location of the knot of these framework 71 securing knotworks among Fig. 6.Different with framework 51 shown in Figure 4, common two are passed lower member 73 and stretch into hole 75a in the upper-part 74 always, and 76b passes connecting strap and extends, and is used to receive two microscler extending elements (for example screw) altogether of the identical mesh that passes knotwork.The hole 75a of adjacent layout only is shown among Fig. 6, among the 75b one complete right because only be a partial view.
Can see from Fig. 7, be not only a two-dimensional structure according to the preferred version of wire rod knotwork of the present invention, and have thickness perpendicular to the knotwork plane, this thickness is greater than the thickness of the single wire rod of this knotwork.Be interpreted as the diagram plane of Fig. 8 for the knotwork plane, promptly this plane in embodiment shown in Figure 8 by whole knots.
Fig. 7 illustrates two wire rods 81,82 that form a knot 83.This knot 83 bendings by two wire rods 81,82 in this example formations of advancing, wire rod 81,82 is owing to this curved course is distinguished roughly semi-ring around another wire rod extension.First wire rod 81 in selected view on top from the right back knot 83 that extends to always, at this knot place forward downwards and in further trend to right front extension.Correspondingly, second wire rod 82, also continues to left back extension downwards from left front this knot that extends to always there backward on top.At this, the zone of extending on top in the drawings of two wire rods 81,82 is positioned at one first plane substantially, and two of wire rod 81,82 are in one substantially at the section shown in the bottom in the drawings and are parallel in second plane on first plane.If these two planes are counted as being determined by the wire rod center then have the about three times spacing of thickness of two wire rods.Correspondingly, wire rod 81,82 is about twice of wire thickness in the zone of spacing at knot 83 of the section shown in the upper and lower in Fig. 7.
Knotwork according to Fig. 8 is referred with label 91.Relate to the knotwork made from wire rod in institute's example, these wire rods constitute by twisting (forming the wire rod rope) with many single line materials respectively again.But alternatively can use the sub-thread wire rod, they are not to be made of some single line materials yet.Wire rod extends substantially from right to left and alternately respectively forms a knot with the wire rod of upside nearest neighbor and the wire rod of downside nearest neighbor in illustrated embodiment.For example represent wire rod shown in Figure 7 with label 81 and 82.
The isolated screen that impacts by the anti-stone of describing by accompanying drawing can obviously reduce in the power that acts under the least favorable situation on the object of fixing this isolated screen.Described worst situation appears when stone strikes on the framework.Because bracing or strutting arrangement has elasticity, directly strike on the rigid objects with stone and compare with identical momentum, this reduces to reach percent 90.If stone strikes on the knotwork, then described power obviously reduces more strongly according to the impingement position difference, is assigned to usually on the more bracing or strutting arrangement in addition.
