(74) Fuldmægtig: Patentbureauet Hofman-Bang & Boutard (54) Anordning til fjedrende fastholdelse af en skinne til et underlag(74) Plenipotentiary: Patent Office Hofman-Bang & Boutard (54) Device for resilient retention of a rail to a substrate

Til fjedrende fastholdelse af skinner mod et underlag er det kendt at anvende neddrevne, fjedrende skinnespigre, der griber direkte ind over skinnefoden, eller fjedrende klemorganer, der er indspændt mellem en i underlaget forankret stiv holder og skinnefoden. Disse anordninger har den ulempe, at den udnyttelige fjeder-00 vej er kort, dvs. at fjederkarakteristikken er stejl, således at 1^, tolerancer i fremstillingen af de indgående dele og unøjagtighe- r\i QQ der i monteringen kan medføre anselige variationer i den kraft, ^ med hvilken skinnen fastholdes til underlaget og hertil kommer, at det isoleringsmellemlæg, der sædvanligt indføres mellem klem-q organet og skinnen, let ødelægges under montagen som følge af, at mellemlægget ikke aflastes ved montagen. På grund af den korte 2 146827 £jedervej ændres også anordningens fjederegenskaber under montering og demontering af skinnerne, hvorfor der ved omlægning af disse ofte må indsættes nye fjederorganer.For resilient retaining of rails against a substrate, it is known to use driven, resilient rails which engage directly over the rails, or resilient clamping means which are clamped between a rigid holder anchored to the substrate and the rails. These devices have the disadvantage that the usable spring-00 path is short, ie. that the spring characteristic is steep such that tolerances in the fabrication of the incoming parts and inaccuracies in the QQ may cause in the assembly considerable variations in the force with which the rail is retained to the substrate and, in addition, the insulation intermediate, which is usually inserted between the clamping member and the rail, is easily destroyed during assembly as a result of the unloading of the spacer during assembly. Due to the short spring travel, the spring properties of the device are also changed during mounting and disassembly of the rails, which means that new spring means must often be inserted when changing these.

Der kendes også en fastholdesesanordning med en lang fjedervej, dvs. med en forholdsvis flad fjederkarakteristik, og opfindelsen angår en sådan anordning, som har en af et fjedrende materiale fremstillet holder, der har et ved siden af skinnen i underlaget forankret endeparti, et fra underlaget opgående og i retning bort fra skinnen bukket mellemparti samt et til en holderpart bukket endeparti, hvilken holderpart griber ind over et klemmeorgan, der strækker sig fra holderen til skinnefodens overside, og som holdes fjedrende presset mod skinnefoden ved hjælp af holderen.There is also known a longitudinal spring retaining device, i.e. The invention relates to such a device having a holder made of a resilient material having an end portion anchored adjacent to the rail in the support, an intermediate portion extending from the support and extending away from the rail, and a a holder portion bent end portion, said holder portion engaging a clamping member extending from the holder to the upper side of the rail foot and which is resiliently pressed against the rail foot by the holder.

Ved den kendte udførelse af en sådan anordning er den fjedrende holder og klemmeorganet udført således, at montering og demontering af skinner er vanskelig, og anordningen egner sig ikke for mekaniseret montage.In the known embodiment of such a device, the resilient holder and the clamping means are designed so that mounting and dismounting of rails is difficult and the device is not suitable for mechanized mounting.

Opfindelsen har til formål at afhjælpe denne ulempe, og dette formål opnås ved, at holderens frie endeparti har form af et mod skinnen åbent U med et øvre, mod skinnen rettet ben og et nedre ben, der går over i holderens mellemparti.The invention aims to alleviate this disadvantage, and this object is achieved by the free end portion of the holder being in the form of an open U facing the rail with an upper, pointed leg and a lower leg extending into the middle portion of the holder.

Ved denne udformning af anordningen er det let ved hjælp af et værktøj at optvinge den ϋ-formede holders fjederben og indføre et klemmeorgan i fjederholderens åbnede spændegab eller fra holderens side, hvorved klemmeorganet indlægges i fjederholderen i ubelastet tilstand og først presses mod skinnefoden, når værktøjet aflastes fra fjederholderen, og hvorved et eventuelt mellem klemmeorganet og skinnefoden indskudt elektrisk isoleringsmellemlæg'kan behandles varsomt uden risiko for ødelæggelse. På grund af holderens store fjedervej foreligger der ikke risiko for ændring af holderens fjedrende egenskaber ved montering og demontering af skinnen, og endvidere vil den ved anordningen udøvede fastholdelseskraft i hovedsagen forblive konstant og uafhængig af enkeltdelenes tolerancevariationer.In this embodiment of the device, it is easy to use a tool to force the spring leg of the ϋ-shaped holder and insert a clamping member in the open clamping gap of the spring holder or from the side of the holder, whereby the clamping means is inserted into the spring holder in the unloaded state and first pressed against the rail foot when the tool is relieved from the spring holder, whereby an electrical insulation intermediate insert inserted between the clamping means and the rail foot can be treated with care without risk of destruction. Due to the large spring path of the holder, there is no risk of changing the spring properties of the holder during mounting and disassembly of the rail, and furthermore, the retaining force exerted by the device will remain substantially constant and independent of the tolerance variations of the individual parts.

En med hensyn til fremstillingen af fjederholderen og dennes fjederegenskaber særlig hensigtsmæssig udførelse kan opnås ved, at holderen er dannet af to fjederblade, der ligger an mod hinan- 3 146827 den sideflade mod sideflade i holderens i underlaget forankrede, og i holderens frie endeparti, men i holderens mellemparti er bukket bort fra hinanden således, at det ene fjederblad har en stor anlægsflade mod underlaget.A particularly convenient embodiment with regard to the manufacture of the spring holder and its spring properties can be obtained in that the holder is formed of two spring blades which abut each other side face against the side surface of the holder in the base and in the free end portion of the holder, but in the middle portion of the holder is bent apart so that one spring blade has a large abutment surface against the substrate.

Opfindelsen skal nedenfor beskrives nærmere under henvisning til tegningen, hvor fig. 1 i perspektivisk afbildning en anordning ifølge opfindelsen med en af to fjederblade udformet holder, fig. 2 et lodret billede delvis i snit af en anden udførelsesfonn for anordningen ifølge opfindelsen med en af et enkelt fjederblad udformet holder, hvor der samtidigt er vist et værktøj til påvirkning af holderen ved montering af en skinne, fig. 3 viser samme set fra oven med værktøjet fjernet, og fig. 4 viser en fjederkarakteristik for holderen ifølge fig. 1.The invention will be described in more detail below with reference to the drawing, in which fig. 1 is a perspective view of a device according to the invention with a holder formed of two spring leaves; FIG. Fig. 2 is a vertical sectional view, partly in section, of another embodiment of the device according to the invention with a single spring blade holder, in which a tool for actuating the holder is shown when mounting a rail; 3 shows the same view from above with the tool removed, and FIG. 4 shows a spring characteristic of the holder according to FIG. First

I fig. 1 er en skinne 2 fjedrende fastholdt til et underlag 1 ved hjælp af en fjedrende holder 3 og 5 samt et klemmeorgan 6.In FIG. 1, a rail 2 is resiliently secured to a support 1 by means of a resilient holder 3 and 5 as well as a clamping member 6.

Den i fig. 1 viste holder består af to fjederblade 4. Disse fjederblade ligger op mod hinanden i et endeparti, der er indesluttet og forankret i underlaget 1, der kan består af beton, jern, træ eller andet egnet materiale. Det ene fjederblad har et mellemparti 5, der strækker sig op fra underlaget 1 på et forholdsvis langt stykke og derefter er bukket bort fra skinnen 2. Det andet fjederblad har et mellemparti 5, der umiddelbart fra overfladen på underlaget er bukket i retning bort fra skinnen 2, hvorved der dannes en stor anlægsflade for fjederbladet mod underlaget, og efter en vis strækning langs underlagets overside er bukket skråt opad mod det andet fjederblad. Fra det sted, hvor mellempartieme 5 mødes, danner fjederbladene 4 et endeparti af holderen, hvor fjederbladene ligger an mod hinanden. Dette endeparti er bukket til et holderparti 3, der har form af et mod skinnen 2 åbent U med et øvre, mod skinnen rettet parti og et nedre parti, der går over i fjederholderens mellemparti 5.The FIG. 1 is made up of two spring blades 4. These spring blades are arranged against one another in an end portion which is enclosed and anchored in the substrate 1, which may consist of concrete, iron, wood or other suitable material. One spring blade has an intermediate portion 5 which extends upwards from the substrate 1 on a relatively long distance and is then bent away from the rail 2. The other spring blade has an intermediate portion 5 which is bent away from the rail immediately from the surface of the base. 2, whereby a large abutment surface is formed for the spring blade against the substrate, and after a certain stretch along the upper surface of the substrate is bent obliquely upwards towards the second spring blade. From the point where the intermediate portions 5 meet, the spring blades 4 form an end portion of the holder where the spring blades abut. This end portion is bent into a holder portion 3, which is in the form of a U open to the rail 2 with an upper portion directed towards the rail and a lower portion extending into the intermediate portion 5 of the spring holder.

Det i fig. 1 viste klemmeorgan 6 har form af et i hovedsagen 4 146827 U-formet rundjern med ombukkede ender, der griber ind i holderen 3's holdeparti 4, og hvor den tværgående del af det U-formede klemmeorgan, hvis midterparti kan være forsynet med en elektrisk isolerende bøsning 7, der ligger an mod oversiden af skinnefoden og holdes fjedrende an mod denne ved indvirkningen fra den fjedrende holder 3. I stedet for isoleringsbøsningen 7 kan man benytte en isolerende mellemlægsplade mellem klemmeorganet 6 og skinnefoden.The FIG. 1 is in the form of a generally U-shaped round iron with bent ends which engages the holding portion 4 of the holder 3, and the transverse part of the U-shaped clamping member, the middle part of which may be provided with an electrically insulating member. bushing 7 which abuts the upper surface of the rail foot and is resiliently held against it by the action of the resilient holder 3. Instead of the insulating bush 7, an insulating intermediate plate can be used between the clamping member 6 and the rail foot.

De to i fjederholderen benyttede fjederblade, der er vist i fig. 1, har gennem deres udformning en forholdsvis lang, udnyttelig fjedervej, dvs. har en forholdsvis svagt hældende fjederkarakteristik som vist i fig. 4.The two spring blades used in the spring holder shown in FIG. 1, through their design has a relatively long, usable spring path, i. has a relatively slightly sloping spring characteristic as shown in FIG. 4th

Ved den i fig. 2 og 3 viste udførelsesform er fjederholderen udført af en enkelt stang af fjedermateriale. Stangen har et i underlaget 1* forankret endeparti, et fra underlaget opstikkende og i retning bort fra skinnen 2 bukket mellemparti 5’ og et til en holder 3' bukket endeparti, der har form af et mod skinnen åbent U med et øvre parti, der er rettet mod skinnen, og et nedre parti, der går over i mellempartiet 5'. Den ene ende af et klemme-organ 6* griber ind i holderens 5 bukkede U-formede endeparti. Klemmeorganet selv er i udførelsesformer, der er vist i fig. 2 og 3, udformet som en bukket bladfjeder, hvis anden ende har et elektrisk isolerende mellemlæg 7' og ligger an mod dette mod skinnefoden. Desuden er vist elektrisk isolerende mellemlægsplader mellem skinnen 2 og underlaget 1 og mellem skinnen 2 og den fjedrende holder 5'.In the embodiment shown in FIG. 2 and 3, the spring holder is made of a single bar of spring material. The rod has an end portion anchored to the base 1 *, an intermediate portion 5 'protruding from the substrate and extending away from the rail 2', and an end portion bent into a holder 3 ', which is in the form of a U-opening open to the rail with an upper portion which is directed to the rail, and a lower portion extending into the intermediate portion 5 '. One end of a clamping member 6 * engages the bent U-shaped end portion of the holder 5. The clamping means itself is in embodiments shown in FIG. 2 and 3, formed as a bent leaf spring, the other end of which has an electrically insulating sheath 7 'and abuts against the rail foot. Also shown are electrically insulating shim plates between the rail 2 and the support 1 and between the rail 2 and the resilient holder 5 '.

Fig. 2 viser endvidere et enkelt værktøj 10 til montering og demontering af klemmeorganet 61. Dette værktøj har en momentarm 11 med en gribeknast 12, der kan indgribe under den øverste kantdel af holderen 3'. Momentarmen 11 har også en tap 13 til forankring af en strop 14, som en mod skinnen 2 hvilende vægtstang 15 kan indføres i. Gennem påvirkning af vægtstangen 15 kan man åbne holderens 3’ endeparti og samtidigt dreje holderen noget bort fra skinnen, så man frit kan indføre klemmeorganets 6' ene ende i holderen 3*s enten fra siden (i skinnens længderetning) eller direkte gennem holderen åbnede U-del til den i fig. 2 viste stilling. Uår værktøjet fjernes, fastklemmer den fjedrende holderFIG. 2 further shows a single tool 10 for mounting and disassembly of the clamping member 61. This tool has a torque arm 11 with a gripping knob 12 which can engage under the upper edge part of the holder 3 '. The torque arm 11 also has a tab 13 for anchoring a strap 14 into which a bar 15 resting against the rail 2 can be inserted. By actuating the bar 15, one can open the end portion of the holder 3 'and at the same time rotate the holder slightly away from the rail, so that one can freely can insert one end of the clamping member 6 into the holder 3 * s either from the side (in the longitudinal direction of the rail) or directly through the holder opened to the holder in FIG. 2. When the tool is removed, the resilient clamp clamps
