Description

Krav 1Requirement 1

Faldsikring med henblik på at hindre frit fald af personer og større genstande ned i korrugeret brøndrør kendetegnet ved at bestå af en ringformet konstruktion fortrinsvis af rustfri stål og som designmæssigt udnytter den indvendige profil i et korrugeret brøndrør fig. 4, 12 og er sammensat og bukket i en given radius Faldsikringen fig. 1 består af fire arme, der alle udgår i symmetriske vinkler siddende på og i forlængelse af 2 vinkelret på hinanden og i et krydsfelt fig. 1,2 sammensatte stænger fig. 1,1 og 3,1. Hver arm fig. 1,3 og 3,3 har for enden vinkelret siddende på denne men i samme plan en afrundet flange fig.1,4. Samlet danner de fire arme fig.1,3 og 3,3 med de afrundede flanger fig. 1,4 en tilsyneladende cirkelrund enhed. På eksemplerne i tegningerne fylder hver af de afrundede flanger ca. 1/8 af en cirkels omkreds. Andre dimensioner med samme princip skal dækkes af beskyttelsen.Fall protection to prevent free fall of persons and larger objects into corrugated well pipes characterized by an annular structure preferably of stainless steel and which design utilizes the internal profile of a corrugated well pipe fig. 4, 12 and is assembled and bent in a given radius. 1 consists of four arms, all extending at symmetrical angles sitting on and in extension 2 perpendicular to each other and in a cross-sectional fig. 1,2 composite bars fig. 1.1 and 3.1. Each arm FIG. 1,3 and 3,3 have an end perpendicular to this but in the same plane a rounded flange fig. 1,4. Altogether, the four arms fig.1,3 and 3.3 with the rounded flanges form fig. 1.4 an apparently circular unit. In the examples in the drawings, each of the rounded flanges fills approx. 1/8 of a circle's circumference. Other dimensions with the same principle must be covered by the protection.

De bukkede og afrundede flanger fig. 1,4 føjer sig naturligt ind i brøndens korrugerede design, således at de fire armes flanger fig. 1,4 kan hvile på kanterne i korrugeret brønds rør.The bent and rounded flanges fig. 1.4 naturally fits into the corrugated design of the well, so that the flanges of the four arms fig. 1.4 may rest on the edges of corrugated well pipes.

Mere detaljeret bliver udhulningerne fig. 4,14 og bugtningerne af det indre af brøndrøret udnyttet som hvilepunkt for den yderste del af faldsikringen - nemlig den afrundede flange fig. 1,4.In more detail, the hollows are shown in FIG. 4.14 and the bends of the interior of the well pipe utilized as a resting point for the outermost part of the fall protection - namely the rounded flange fig. 1.4.

Selve flangerne sidder i et stativ på armene fig. 1,3 og er i det væsentlige af plast.The flanges themselves sit in a rack on the arms fig. 1.3 and is essentially plastic.

Krav 2Requirement 2

Faldsikring ifølge krav lkendetegnet ved at armene fig. 1,3 og 3,3 er bevægelige således at de kan skubbes ind mod midten af faldsikringen fig. 1 og fig. 4,15 og ud derfra igen.Fall protection according to claim characterized in that the arms fig. 1.3 and 3.3 are movable so that they can be pushed in towards the center of the fall protection fig. 1 and FIG. 4.15 and out of there again.

Hver af armene fig. 1,3 og 3,3 i eksemplet er fæstnet udenpå en udfra centrum gående kort flad stang (arm) fig,1,1 og 3,1 og som på hver af langsiderne er forsynet med en sideflade ved at kanterne er bukket lodret. I hver af siderne og over for hinanden er på disse sideflader boret to umiddelbart i forlængelse af hinanden men med et lille mellemrum rektangulære skinner eller spor fig. 2,6 og 3,6. Armene fig. 1,3 og 3,3 er i princippet næsten fysisk dimensionerede identiske med de ovenfor nævnte fra centrum af faldsikringen udgående stænger fig. 1,1 og 3,1 -forskellen er at armene fig. 1,3 er længere og en smule bredere. På grund af den lidt smallere bredde "kører" de fra centrum i krydsfeltet fig. 1,2 sammensatte udgående stænger fig. 1,1 og 3,1 som på skinner inde i de lidt bredere arme fig. 1.3 og 3,3 og fæstnes yderligere i samme igennem de førnævnte spor fig. 1, 6 og 2,6 hvorigennem skruer fig. 1,7 og 2,7 er ført. Skruerne fig. 1,7 og 2,7 spændes med møtrikker.Each of the arms FIG. 1,3 and 3,3 in the example are attached to a short flat rod (arm) fig. 1,1 and 3,1, which is projected from the center and which is provided on each of the long sides with a side surface by the edges being bent vertically. In each of the sides and opposite each other two boring two are immediately adjacent to each other but at a small space rectangular rails or grooves fig. 2.6 and 3.6. The arms fig. 1,3 and 3,3 are in principle almost physically dimensioned identical to those mentioned above from the center of the fall protection fig. 1.1 and 3.1 the difference is that the arms of FIG. 1.3 is longer and slightly wider. Due to the slightly narrower width, they "drive" from the center of the intersection fig. 1,2 composite output rods FIG. 1.1 and 3.1 as on rails inside the slightly wider arms of FIG. 1.3 and 3.3 and are further secured in the same through the aforementioned tracks fig. 1, 6 and 2.6 through which screws fig. 1.7 and 2.7 are posted. The screws fig. 1.7 and 2.7 are tightened with nuts.

For enden af den smalle ende af hver af de fire flanger fig. 1.4 er i det væsentlige skruet støttearme fig. 1,5 på. Disse støttearme fig. 1,5 er bukket og vinklet således at de i den modsatte ende er fæstnet ved hjælp af samme skruer fig. 1,6 og 2,6 som armene fig. 1,3 og 3,3 er fæstnet på med. Bl.a. på grund af nævnte skruer fig. 1,7 og 2,7 der føres igennem de rektangulære borede spor fig. 1,6 og 2,6 -igennem både armene fig. 1,3 og 3,3 og de fra centrum udgående stænger 1,1 og 3,1 samt støttearmene fig. 1,5 -kan armene fig. 1,3 og 3,3 og flangerne fig. 1,4 nu positioneres i ønskede stillinger.At the end of the narrow end of each of the four flanges FIG. 1.4 is essentially screwed support arms FIG. 1.5 on. These support arms fig. 1.5 is bent and angled so that they are fixed at the opposite end by the same screws fig. 1.6 and 2.6 as the arms FIG. 1.3 and 3.3 are attached to the med. Among other things. due to said screws fig. 1.7 and 2.7 passing through the rectangular drilled grooves fig. 1.6 and 2.6 - Through both arms FIG. 1,3 and 3,3 and the bars extending from the center 1,1 and 3,1 and the support arms fig. 1.5 - the arms fig. 1.3 and 3.3 and the flanges of FIG. 1.4 is now positioned in desired positions.

Inde i armen fig. 1,3 og 3,3 og toppen af samme er der placeret en i passende længde låseplade 2,8 og 3,8 fortrinsvist af hårdt stål og som er fæstnet i den ene ende (fjernest fra centrum) med fortrinsvist 2 nitter fig. 1,9 og 3,9. En væsentlig del af låsepladen 2,8 og 3,8 er således uden fæstning og er dermed fysisk manipulerbar og kan som sådan løftes ud over en forholdsvis kort tap fig. 1,10. Nar låsepladen 2,8 og 3,8 hviler på tappen fig. 1,10 og 3,10 kan man bevæge armene fig. 1,3 og 3,3 frem og tilbage.Inside the arm FIG. 1,3 and 3,3 and the top of the same is arranged a suitable length lock plate 2.8 and 3.8 preferably of hard steel and which is fixed at one end (furthest from the center) with preferably 2 rivets fig. 1.9 and 3.9. Thus, a substantial part of the locking plate 2.8 and 3.8 is without attachment and is thus physically manipulable and as such can be lifted beyond a relatively short pin fig. 1.10. When the locking plate 2.8 and 3.8 rests on the pin fig. 1, 10 and 3, 10 the arms can be moved. 1.3 and 3.3 back and forth.

Nar låsepladen 2,8 og 3,8 er bag tappen fig. 1,10 og 3,10 er armen fig. 1,3 og 3,3 låst fast i yderposition og dermed i position tilpasset til fæstning inde i brønden. I denne position hviler det yderste af låsepladen fig. 2,8 og 3.8 på det yderste af toppen af den fra centrum udgående arm fig. 1,1 og 3,1. Låsepositionen er afpasset således at armene fig. 1,3 og 3,3 i denne position vil være optimalt presset ind imod den valgte hulning i det indre af brønden. Låsepladen fig. 2,8 og 3,8 skubbes fra låsepositionen ned over tappen fig. 1,10 og 3,10 ved at presse låsepladen fig. 2.8 og 3,8 med en spids genstand igennem et hul fig. 1,11 og 3,11 i armen fig. 1,3 og 3,3 positioneret ovenover det yderste af låsepladen fig. 2,8 og 3,8.When the locking plate 2.8 and 3.8 are behind the pin fig. 1, 10 and 3, 10 are the arm of FIG. 1,3 and 3,3 locked in outer position and thus in position adapted for attachment inside the well. In this position, the outermost of the lock plate rests fig. 2.8 and 3.8 on the outermost of the top of the arm extending from the center fig. 1.1 and 3.1. The locking position is adjusted so that the arms fig. 1.3 and 3.3 in this position will be optimally pressed against the selected hole in the interior of the well. The lock plate fig. 2.8 and 3.8 are pushed from the locking position down over the pin fig. 1, 10 and 3, 10 by pressing the lock plate fig. 2.8 and 3.8 with a pointed object through a hole FIG. 1.11 and 3.11 in the arm of FIG. 1.3 and 3.3 positioned above the outermost of the locking plate fig. 2.8 and 3.8.

Et lille stykke værktøj til formålet i en kort kæde kan hænge i bekvem nærhed af hullet fig. 1,11 og 3,11.A small tool for the purpose of a short chain can hang in convenient proximity to the hole fig. 1.11 and 3.11.

Ved indad mod centrum gående bevægelse tvinges armen fig. 1,3 og 3,3 dybere ind over den fra centrum udgående arm - kroppen fig. 1,1 og 3,1.When moving inwards towards the center, the arm fig. 1.3 and 3.3 deeper into the arm extending from the center - the body fig. 1.1 and 3.1.

Selve princippet med ind- og udskubningsmuligheden er vigtig - teknik og metode måske mindre, idet andre lignende teknikker og metoder til samme formål vil kunne forestilles.The principle of push-in and push-out is important - technique and method maybe less, as other similar techniques and methods for the same purpose can be imagined.
