SAKERHETSSKENA FOR ATT SKYDDA EN PERSON FRAN FALL SAMT LoPARE OCH SAKERHETSSYSTEM MED EN SADAN SKENA UPPFINNINGENS OMRADE Uppfinningen avser en sakerhetsskena ingaende i ett system for att skydda en person fran fall fran, varvid sakerhetsskenan inrattad far fastsattning langs en passage pa strukturen, varvid sakerhetsskenan är inrattad for samverkan med en forflyttbar lapare med ett faste for samverkan med en med personen forbunden sakerhetslina, och varvid sakerhetsskenan uppvisar organ for lasning av loparen i en sparriktning. Uppfinningen avser ¥ en lopare jamte ett sakerhetssystem. FIELD OF THE INVENTION The invention relates to a safety rail included in a system for protecting a person from falling from for co-operation with a movable loader with a fixed for co-operation with a safety line connected to the person, and wherein the safety rail has means for loading the runner in a saving direction. The invention relates to a runner and a security system.
UPPFINNINGENS BAKGRUND Det är allnant forut }cant att pa byggnadstak inratta infastningsanordningar for sakerhetshakar till sakerhetslinor i andamal att undvika fatala fall fran ifragavarande byggnader. Sadana fastpunkter kan vara olika typer av skyddsracken, konsolfasten, stegar m m. Ett problem med kanda infastningsanordningar az- att en takarbetare behover manuellt omplacera sin sakerhetslina vid passage av konsoler och liknande, som bryter kontinuiteten hos en langstrackt infastningsanordning sasom en skena. BACKGROUND OF THE INVENTION It is generally advisable to install fastening devices for safety hooks to safety ropes on building roofs in order to avoid fatal cases from the buildings in question. Such fixed points can be different types of protective rack, bracket bracket, ladders, etc. A problem with known fasteners is that a roofing worker needs to manually reposition his safety line when passing brackets and the like, which breaks the continuity of an elongated fastener such as a rail.
For att undvika sadana problem är forut kant att inratta sakerhetsvajrar med speciella, pa avstand fran varandra inrattade fastanordningar, samt lopare, vilka ar konstruerade sa att de automatiskt kan overbrygga en dylik speciell fastanordning utan att ingreppet med vajern behover frigoras. Detta arrangemang ar emellertid kostsamt och komplicerat samt inte i varje situation klanderfri. In order to avoid such problems, it is preferable to set up safety wires with special, spaced-apart fastening devices, as well as runners, which are designed so that they can automatically bridge such a special fastening device without the intervention with the wire having to be released. However, this arrangement is costly and complicated and not in every situation flawless.
Som exempel pa teknikens bakgrund kan namnas US 2010/0012426 Al, US 4 269 284. 1 UPPFINNINGENS ANDAMAL OCH VIKTIGASTE KANNETECKEN Det dr ett hndamal med foreliggande uppf inning att tillhandahalla en shkerhetsskena jhmte ett system och en 18pare av inledningsvis kant slag, vid vilka problemen med bakgrundstekniken atminstone lindras. Examples of the prior art are US 2010/0012426 A1, US 4,269,284. 1 OBJECTS AND MOST IMPORTANT CHARACTERISTICS OF THE INVENTION It is an object of the present invention to provide a safety rail with a system and an 18 pair of initial edge type, in which the problems with the background technique at least alleviated.
Detta astadkommes vid en shkerhetsskena ingaende i ett system for att skydda en person fran fatala fall fran en struktur, varvid shkerhetsskenan hr langstrhckt och i huvudsak remsformig och inrattad for fastshttning lhngs en passage pa strukturen, varvid shkerhetsskenan uppvisar en fOrsta och en andra lhngskant, varvid sakerhetsskenan hr inrhttad for samverkan med en forflyttbar 16pare med ett fhste for samverkan med en med personen f6rbunden shkerhetslina, och varvid sakerhetsskenan uppvisar organ for lasning av 16paren i en sparriktning genom att den forsta langskanten uppvisar ett flertal hakelement med vardera en i huvudsak motsatt sphrriktningen riktad hakyta for lasningsingrepp med ett parti av lOparen, att den andra langskanten forloper med en utdragen meanderform med alternerande inbuktningar och utbuktningar, att varje inbuktning och varje hakelement är positionerade mitt for varandra, och att varje utbuktning är positionerad mitt for ett parti mellan tva hakelement. Dessa senare hakelement hr harvid intilliggande. This is achieved by a safety rail entering a system for protecting a person from fatal falls from a structure, the safety rail being elongate and substantially strip-shaped and arranged for attachment along a passage on the structure, the safety rail having a first and a second longitudinal edge. the safety rail is arranged for co-operation with a movable 16 pair with a first for co-operation with a safety line connected to the person, and the safety rail has means for loading the 16 pairs in a saving direction in that the first longitudinal edge has a plurality of hook elements with each hook surface for welding engagement with a portion of the lopar, that the other longitudinal edge extends with an elongated meander shape with alternating indentations and bulges, that each indentation and each hook element are positioned opposite each other, and that each bulge is positioned midway between a portion between two hook elements. These later hook elements here are adjacent.
Genom hakelementen pa den f8rsta lhngskanten i kombination med den speciella utdragna meanderformen pa den andra langskanten uppnas att 16paren vid passage av en utbuktning inriktas respektive sidoforflyttas respektive vinklas sá att 16paren effektivt kommer i lAsningsingrepp med hakytan hos ett intilliggande hakelement. Through the hook elements on the first longitudinal edge in combination with the special elongated meander shape on the second longitudinal edge, it is achieved that the pairs are aligned and laterally displaced and angled, respectively, when passing a bulge, so that the 16 pairs effectively engage with the hook surface of an adjacent hook element.
Shkerhetslinan sphrras clamed effektivt efter redan en mycket kort reirelse has 16paren, varvid den fallande personen effektivt kommer att uppfangas. I synnerhet kommer 2 utbuktningarna hos sakerhetsskenan att ombesorja en forflyttning av en fallande eller okontrollerat nedat sig forflyttande lopare i riktning av att sakert kunna uppfangas av hakytan. The shear line is traced clamed effectively after already a very short movement has 16 pairs, whereby the falling person will be effectively captured. In particular, the bulges of the safety rail will provide for a movement of a falling or uncontrolled downwardly moving runner in the direction of being able to be safely caught by the hook surface.
Laparen i sin helhet sidoforflyttas namligen av utbuktningen sa att det parti av loparen som kommer if raga for ingrepp med hakytan forflyttas narmare ett parti av sakerhetsskenan mellan tva hakelement. Vid den fortsatta hastiga fallrorelsen kvarstannar sedan laparen i ett sadant lage visavi sakerhetsskenan. En ytterligare funktion av utbuktningarna ar en tendens till omvinkling av loparen visavi sakerhetsskenan, medforande effektivt ingrepp med hakytan och undvikande av att arbetaren skadas. Namely, the runner in its entirety is moved laterally by the bulge, so that the part of the runner which comes into contact with the hook surface is moved closer to a portion of the safety rail between two hook elements. During the continued rapid fall movement, the runner then remains in such a position vis-à-vis the safety rail. A further function of the bulges is a tendency to deflect the runner vis-à-vis the safety rail, entailing effective engagement with the hook surface and avoiding injury to the worker.
En viktig fordel med uppfinningen är att en lopare kan utnyttjas som saknar rorliga delar for att tillhandahalla lasningen. Harigenom undviks problem med karvande delar pa grund av intrangande smuts, frysande vatten etc. Konstruktionen blir bade robust, tillforlitlig och ekonomiskt fordelaktig. En star fordel ar anvandning vid master, varvid mycket langa sakerhetsskenor kan installeras enkelt och till lagt pris. Sakerhetsbyglar, vilka omger stegar kan bortfalla. Sam foredragna alternativ forloper den andra langskanten flackt sinusformat eller flackt sicksackartat eller i en av cirkelbagpartier beskriven meanderkurvform eller i en kombination av dessa alternativ. An important advantage of the invention is that a runner can be used which lacks movable parts to provide the welding. This avoids problems with carving parts due to penetrating dirt, freezing water, etc. The construction is both robust, reliable and economically advantageous. A major advantage is use with masts, whereby very long safety rails can be installed easily and at an added price. Safety bars, which surround ladders, can be omitted. As preferred alternatives, the second longitudinal edge extends flatly sinusoidal or flat zigzag or in a meander curve shape described by circular rear portions or in a combination of these alternatives.
Hakytan bildar lampligen en mot en motsatt sparriktningen appen vinkel med en utstrackningsriktning for sakerhetsskenan, varvid ska forstas att en huvudsaklig utstrackning avses dar langskanternas form bortses fran. The chin surface appropriately forms an angle opposite to the opposite saving direction app with an extension direction for the safety rail, it being understood that a main extension is meant where the shape of the longitudinal edges is disregarded.
Namnda vinkel ãr foredraget en spetsig vinkel och faretradesvis mellan 60° och 90° mot utstrackningsriktningen. Det är lampligt att sakerhetsskenan uppvisar organ far anbringning darav pa en takstege, en husfasad, en mast 3 eller ett konsolarrangemang. Namnda organ ãr lampligen fasthal far genomgang av fastelement, utskjutande vinklar eller bultar etc. Said angle is preferably an acute angle and preferably between 60 ° and 90 ° to the direction of extension. It is appropriate for the safety rail to have means for mounting it on a roof ladder, a house facade, a mast 3 or a bracket arrangement. The said means are suitably fixed for passage of fastening elements, projecting angles or bolts, etc.
Uppfinningen avser aven en lopare ingaende i ett system for att skydda en person fran fatala fall fran en struktur, varvid loparen uppvisar ett faste for samverkan med en med personen forbunden sakerhetslina, varvid laparen âr inrattad att vara forflyttbar pa en Lai-1gs en passage pa strukturen anordnad sakerhetsskena enligt ovan, och varvid laparen ar inrattad att lasas pa sakerhetsskenan i en sparriktning. Enligt uppfinningen ãr fastet inrattat pa ett parti av loparen, som är placerat i sidled av och vasentligen i linje med ett huvudplan genom ett utrymme far formbindande mottagning av sakerhetsskenan. Loparen uppvisar ett parti for lasningsingrepp med pa en forsta langskant av sakerhetsskenan inrattade hakelement med vardera en i huvudsak motsatt sparriktningen riktad hakyta. The invention also relates to a runner entering a system for protecting a person from fatal cases from a structure, wherein the runner has a fastener for co-operation with a safety line connected to the person, the runner being arranged to be movable on a Lai-1gs a passage on the structure arranged safety rail as above, and wherein the runner is arranged to be loaded on the safety rail in a saving direction. According to the invention, the fastener is arranged on a portion of the runner, which is placed laterally of and substantially in line with a main plane through a space receiving form-binding reception of the safety rail. The runner has a portion for loading engagement with hook elements arranged on a first longitudinal edge of the safety rail, each with a hook surface directed substantially opposite the saving direction.
Motsvarande fordelar som for sakerhetsskenan uppnas genom den uppfinningsenliga loparen. Corresponding advantages which for the safety rail are obtained through the runner according to the invention.
Loparen uppvisar lampligen Over sin langd en oppning till namnda utrymme far passage av fastorgan vid forflyttning av loparen langs sakerhetsskenan. Med "langd" avses har parallellt med sakerhetsskenans utstrackningsriktning. The runner suitably has, over its length, an opening to the said space for the passage of fixed means when the runner moves along the safety rail. By "length" is meant has parallel to the direction of extension of the safety rail.
Loparen uppvisar vidare lampligen en utvidgning av namnda utrymme mitt far namnda Oppning for passage av skruv- /nitskallar/muttrar etc. The runner further appropriately shows an extension of the said space with the father called the opening for passage of screw / rivet heads / nuts etc.
Ett uppfinningsenligt system for att skydda en person fran fatala fall fran en struktur, inkluderar atminstone en sakerhetsskena och atminstone en lopare enligt ovan. An inventive system for protecting a person from fatal falls from a structure includes at least one safety rail and at least one runner as above.
KORTFATTAD BESKRIVNING AV RITNINGAR Uppfinningen ska nu narmare beskrivas med ledning av 4 utforingsexempel och med referens till de bifogade ritningarna, pa vilka: Fig. 1 illustrerar ett system enligt uppfinningen med en lapare visad i olika lagen pa en sakerhetsskena, Fig. 2 visar loparen i en andvy, och Fig. 3 visar ett system enligt uppfinningen anordnat vid en byggnadsstruktur. BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be described in more detail with reference to 4 embodiments and with reference to the accompanying drawings, in which: Fig. 1 illustrates a system according to the invention with a runner shown in different layers on a safety rail, Fig. 2 shows the runner in a view, and Fig. 3 shows a system according to the invention arranged at a building structure.
BESKRIVNING AV UTFoRINGSEXEMPEL I fig. 1 illustreras ett system enligt uppfinningen inkluderande en sakerhetsskena 2, pa vilken ar formbundet anbragt en lapare 3 med ett faste 4 for mottagande av en karbinhake eller liknande i anden av en sakerhetslina. Till yttermera visso är pa sakerhetsskenan 2 loparen 3 visad i tre olika positioner P1, P2 och P3 far illustration av den uppfinningsenliga funktionen, vilket kommer att framga av det nedanstaende. DESCRIPTION OF EMBODIMENTS Fig. 1 illustrates a system according to the invention including a safety rail 2, on which a lapar 3 is fixedly mounted with a fixed 4 for receiving a carabiner or the like in the spirit of a safety line. Furthermore, on the safety rail 2, the runner 3 is shown in three different positions P1, P2 and P3, illustrating the function according to the invention, which will appear from the following.
Sakerhetsskenan 2 ãr i huvudsak langstrackt och remsformad pa sá satt att den uppvisar tva bredsidor, av vilka en framgar av sidovyn i fig. 1 liksom en forsta langskant Kl utgarande en forsta smalsida och en andra langskant K2 utgorande en andra smalsida for sakerhetsskenan 2. The safety rail 2 is substantially elongate and strip-shaped in such a way that it has two wide sides, one of which appears from the side view in Fig. 1 as well as a first longitudinal edge K1 forming a first narrow side and a second longitudinal edge K2 constituting a second narrow side for the safety rail 2.
Den forsta langskanten Kl uppvisar pa sin sida ett antal i sidled utskjutande hakelement 7 fOrdelade efter sin utstrackning U, vilka hakelement 7 vardera uppvisar en hakyta 8, vilken i huvudsak ãr riktad i motsatt en sparriktning S far systemet. Med sparriktning S innebar att loparen 3 är sparrad mot vidare rorelse i riktning S genom ingrepp med ett hakelement 7. The first longitudinal edge K1 has on its side a number of laterally projecting hook elements 7 distributed according to their extent U, which hook elements 7 each have a hook surface 8, which is substantially directed in the opposite direction to a saving direction S for the system. With spar direction S meant that the runner 3 is sparred against further movement in direction S by engagement with a hook element 7.
Av detaljforstoringen tillhorande fig. 1 framgar att varje hakelement 7 har en flack flank, vilken medger att laparen 3 bekvamt kan foras forbi hakelementet 7 i riktning motsats sparriktningen S. Vidare framgar att hakytan 8 i det visade utforingsexemplet ãr v&sentligen plan och bildar en vinkel a, vilken är oppen och foretradesvis spetsig mellan 600 och 900 mot en utstrackningsriktning U for sakerhetsskenan 2. Varje inbuktning 6 och varje hakelement 7 a" positionerade mitt for varandra och varje utbuktning 5 ár positionerad vasentligen mitt for ett parti 10 mellan tva hakelement. Sammantaget är avstandet mellan ytterst belagna punkter pa langssidorna K1 och K2 i varje tvarsektion tilltaget sa, i forhallande till loparens dimensioner, att leparen är formbundet fasthallen pa sakerhetsskenan 2 Over hela dess langsutstrackning. From the detail enlargement belonging to Fig. 1 it appears that each hook element 7 has a flat flank, which allows the lapar 3 to be conveniently passed past the hook element 7 in the direction opposite the saving direction S. Furthermore, it appears that the hook surface 8 in the shown embodiment is substantially flat and forms an angle a , which is open and preferably pointed between 600 and 900 towards an extension direction U of the safety rail 2. Each bulge 6 and each hook element 7a "are positioned opposite each other and each bulge 5 is positioned substantially in the middle of a portion 10 between two hook elements. the distance between the extremely occupied points on the longitudinal sides K1 and K2 in each transverse section has increased so, in relation to the dimensions of the runner, that the runner is form-fittingly fixed to the safety rail 2 over its entire longitudinal extent.
I praktiken motsvarar liar-yid hakelementens grad av utskjutning i sidled av inbuktningarnas grad av inbuktning. Utbuktningarnas dimension i sidled motsvaras av sidledsavstandet mellan en linje genom partiet 10 och en linje mellan hakelementens yttersta andar. In practice, the degree of extension of the hook elements laterally corresponds to the degree of indentation of the indentations. The lateral dimension of the bulges corresponds to the lateral distance between a line through the portion 10 and a line between the outermost ends of the hook elements.
Uppfinningen f5rklaras enklast med ledning av de i fig. 1 visade positionerna P1, P2, P3 far 15paren 3 pa sakerhetsskenan 2. I det oversta laget, P1, i fig. 1 har en del av loparen 3, som befinner sig motsatt positionen for fastet 4, kommit till anliggning mot en byre flank av en utbuktning 5. Detta innebar en inriktning av fastet 4 i riktning av en invinkling av 15parens 3 parti 18 f5r ingrepp med en hakyta sa att detta parti 18 kommer att befinna sig i direkt narhet av ett parti 10 mellan tva utskjutande hakelement 7. The invention is most easily explained with reference to the positions P1, P2, P3 shown in Fig. 1 for the pair 3 on the safety rail 2. In the uppermost layer, P1, in Fig. 1, a part of the runner 3, which is opposite the position of the fastener, has 4, came into abutment against a burr flank of a bulge 5. This meant an alignment of the fastener 4 in the direction of an angle of the portion 18 of the pair 3 for engagement with a hook surface so that this portion 18 will be in direct proximity to a portion 10 between two projecting hook elements 7.
I det mittre laget, P2, har laparen 3 fortsatt att rora sig nerat langs sakerhetsskenan 2 och aven ett Ovre parti darav har nu forskjutits sá att hela loparen 3 forskjutits for att vara vasentligen i direkt narhet av namnda parti 10 mellan tva hakelement. In the middle layer, P2, the runner 3 has continued to move down along the safety rail 2 and also an upper part thereof has now been displaced so that the entire runner 3 has been displaced to be substantially in direct proximity to said portion 10 between two hook elements.
Vid loparens fortsatta (okontrollerade) rorelse nedat pa grund av ett fall, kommer nu omedelbart efter den mittre 6 positionen, P2, av loparen 3 0 fig. 1, partiet 18 att komma till sakert lasningsingrepp med hakytan 8, varvid fortsatt rorelse i sparriktningen S ar omajlig for laparen 3. En person med en sakerhetslina kopplad till loparen 3 kommer saledes att uppfangas av sakerhetslinan och ett fatalt fall kan undvikas. In the case of the runner's continued (uncontrolled) movement downwards due to a fall, immediately after the middle position 6, P2, of the runner 30 in Fig. 1, the portion 18 will come into a secure welding engagement with the hook surface 8, whereby continued movement in the saving direction S is impossible for the runner 3. A person with a safety line connected to the runner 3 will thus be caught by the safety line and a fatal fall can be avoided.
Det nedre laget, P3, i fig. 1 for loparen 3 illustrerar hur laparen 3 kontrollerat kan bringas att passera nedat fOrbi ett hakelement 7 genom att lata loparen rora sig nedat mot verkan av en i fastet 4 med en kraft uppat verkande sakerhetslina (visas med streckad linje och betecknad med 12). The lower layer, P3, in Fig. 1 for the runner 3 illustrates how the runner 3 can be controlled to pass downwards past a hook element 7 by letting the runner move downwards against the action of a safety line acting in the fastener 4 (shown with dashed line and denoted by 12).
Genom fastets placering kommer nu 18paren 3 att snedstallas under sin rOrelse mot hakytan 8 sã att loparen 3 utan problem kan bringas att passera hakelementet 7. Due to the position of the fastener, the pair 18 will now be inclined during its movement towards the hook surface 8 so that the runner 3 can be made to pass the hook element 7 without problems.
Av andvyn i fig. 2 framgar utformningen av loparen 3 mer i detalj, varvid framgar att fastet 4 ar inrattat i sidled av ett utrymme 17 for mottagning av sakerhetsskenan 2 och i synnerhet i linje med ett huvudplan H genom detta utrymme 7 och en mottagen sakerhetsskena. Detta sett i en riktning R vinkelratt mot huvudplanet H. The view in Fig. 2 shows the design of the runner 3 in more detail, it being seen that the fastener 4 is arranged laterally of a space 17 for receiving the safety rail 2 and in particular in line with a main plane H through this space 7 and a received safety rail . This seen in a direction R perpendicular to the main plane H.
