Opfindelsen angår et fastgørelsesorgan til vaskekummer eller lignende elementer, der ikke frembyder mulighed for anvendelse af værktøjer til fastholdelse af dele af fastgørelsesorganet mod drejning om fastgørelsesorganets længdeakse under tilspændingen af fastgørelsesorganet og bestående af en skrue og et kraftoptagende forholdsvis stift tværstykke, som er indrettet til indføring gennem slidsformede åbninger i elementet, der skal fastgøres, og til ved spænding af skruen at forskydes i retning mod skruens hoved til anlæg mod en indvendig flade i elementet til forbindelse af dette med en konsol.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a wash basin fastener or similar elements which do not allow the use of tools for holding portions of the fastener against rotation of the longitudinal axis of the fastener during tightening of the fastener and consisting of a screw and a power receiving relatively rigid crosspiece adapted for insertion. through slit-shaped openings in the element to be fastened, and to be displaced in the direction of tension of the screw in the direction of the head of the screw to abut an inner surface of the element for connecting it with a bracket.

Ved et fastgørelsesorgan af denne art, som kendes fra beskrivelsen til svensk patent nr. 220.984 er skruehullet placeret asymmetrisk i tværstykket for at opnå en låsning af dette mod drejning, når det er ført ind i hulrummet i vaskekummen. Dette kendte fastgørelsesorgan er behæftet med den ulempe, at montøren kun har ringe kontrol med tværstykkets orientering under monteringen, hvilket kan medføre vanskeligheder under monteringsarbejdet og en upålidelig forankring.By a fastener of this kind known from the specification of Swedish Patent No. 220,984, the screw hole is positioned asymmetrically in the crosspiece to obtain a locking thereof against rotation when it is inserted into the cavity of the wash basin. This known fastening means suffers from the disadvantage that the installer has little control over the orientation of the crosspiece during mounting, which can cause difficulties during mounting work and an unreliable anchoring.

Ved et andet fra beskrivelsen til svensk patent nr. 321.898 kendt fastgørelsesorgan dannes tværstykket under selve tilspændingen af fastgørelsesorganet ved, at øvre afsnit af to eller flere bøjelige strimmelformede organer, der forbinder en i anlæg mod undersiden af en monteringskonsol anbragt og med en gennemgangsboring for en spændeskrue udformet hoveddel og en gennem den slidsformede åbning i elementet, der skal fastgøres ført endedel med en gevindboring for spændeskruen, udbøjes mod siderne, når endedelen ved hjælp af spændeskruen trækkes nedad i retning mod hoveddelen. De strimmelformede organer kommer under deres udbøjning først til anlæg mod de øverste længdekanter af den slidsformede åbning i elementet og bøjes under deres fortsatte udbøjning hen over de nævnte længdekanter og fastholder derved elementet til konsollen. For at de strimmelformede organer ikke skal beskadige porcelænsmaterialet ved åbningens længdekanter, er de fremstillet af et forholdsvis blødt materiale, fortrinsvis formstof. De partier af de strimmelformede organer, der bøjes hen over åbningens længdekanter, er udsat for trækkræfter, medens de øverste partier af de strimmelformede organer er udsat for trykkræfter i deres længderetning.efter tilspændingen. Disse partier vil derfor efterhånden give efter for henholdsvis trækkræfterne og trykkræfterne, og den forankring, der er opnået, vil derfor efterhånden løsnes.In another attachment member known from the specification of Swedish Patent No. 321,898, the crosspiece is formed during the actual tightening of the attachment means by the upper sections of two or more flexible strip-shaped members connecting one abutting to the underside of a mounting bracket and with a passage bore for a a head screw and a through-hole opening in the element to be secured guided end portion with a threaded bore for the head screw are bent towards the sides as the end member is pulled downwards in the direction towards the head part by means of the head screw. The strip-shaped members, during their bending, first come into contact with the upper longitudinal edges of the slit-shaped opening in the element and bend during their continued bending over said longitudinal edges, thereby holding the element to the bracket. In order that the strip-shaped members do not damage the porcelain material at the longitudinal edges of the opening, they are made of a relatively soft material, preferably plastic. The portions of the strip-shaped members bent over the longitudinal edges of the opening are subjected to tensile forces, while the upper portions of the strip-shaped members are subjected to compressive forces in their longitudinal direction, following the tension. These parts will therefore eventually yield to the tensile and compressive forces, respectively, and the anchoring obtained will therefore gradually loosen.

Formålet med den foreliggende opfindelse er at tilvejebringe et fastgørelsesorgan af den indledningsvis nævnte art, ved hvilket de nævnte ulemper er elimineret.The object of the present invention is to provide a fastener of the kind mentioned in the beginning, by which said disadvantages are eliminated.

Dette opnås ifølge opfindelsen ved, at der mellem tværstykket og en hoveddel, som ligger an mod den mod skrueskaftet vendende side af skruens hoved, er anbragt et holdeorgan bestående af i det mindste in bøjelig strimmel, som forbinder tværstykket og hoveddelen med hinanden og er indrettet til, når tværstykket og hoveddelen bevæges mod hinanden ved spænding af skruen, at bøje ud i retningen i det mindste tilnærmelsesvis vinkelret på det længdeplan gennem skruen, hvori også de yderste ender af tværstykket ligger og derved at forhindre drejning af tværstykket om skruens akse i forhold til hoveddelen. Herved opnås, at tværstykket frit kan udformes på den mest hensigtsmæssige måde under hensyntagen til formen af slidsåbningerne i de aktuelle vaskekummer eller konsoller, herunder de indre hulrum i sådanne vaskekummer, og endvidere opnås at tværstykket kan gøres tilstrækkeligt stift til, at der ikke opstår problemer med eftergivelighed. Den eller de bøjelige strimler tjener ved fastgørelsesorganet ifølge opfindelsen udelukkende til at holde tværstykket i en fikseret stilling i forhold til hoveddelen under monteringen og spændingen af skruen og bidrager således på ingen måde til selve forankringen, idet strimlen eller strimlerne bøjer sig frit Udad i de slidsformede åbninger i henholdsvis vaskekummen og konsollen.This is achieved according to the invention in that between a transverse piece and a main part which abuts against the side of the screw head facing the screw shaft, there is arranged a holding means consisting of at least a flexible strip which connects the transverse piece and the body part to each other and is arranged to bend in the direction at least approximately perpendicular to the longitudinal plane through the screw when the transverse piece and the body are moved towards each other by tensioning the screw, in which also the outer ends of the transverse piece lie, thereby preventing rotation of the transverse axis about the screw's ratio to the main body. Hereby it is achieved that the crosspiece can be freely designed in the most convenient manner, taking into account the shape of the slit openings in the current wash basins or brackets, including the inner cavities of such wash basins, and furthermore, the crosspiece can be made sufficiently rigid that no problems arise. with resilience. The flexible strip (s) serve by the fastener according to the invention solely to hold the crosspiece in a fixed position with respect to the main part during mounting and tensioning of the screw and thus in no way contributes to the anchorage itself, the strip or strips bending freely outwardly in the slotted molds. openings in the sink and the console, respectively.

Opfindelsen forklares nærmere i det følgende under henvisning til tegningen. På tegningen viser:The invention will be explained in more detail below with reference to the drawings. In the drawing:

Fig. 1 et fastgørelsesorgan ifølge opfindelsen under indføringen i åbningerne i henholdsvis en vaskekumme og en konsol for denne, fig. 2 det i fig. 1 viste fastgørelsesorgan drejet 90° om skruens akse, og fig. 3 fastgørelsesorganet i spændt stilling.FIG. 1 shows a fastener according to the invention during insertion into the openings in a wash basin and a bracket respectively, FIG. 2 shows the embodiment of FIG. 1, 90 ° rotates about the axis of the screw, and FIG. 3 in the tensioning position in the tensioned position.

Fastgørelsesorganet på tegningen omfatter et tværstykke 4, en skrue 5, som er forsynet med et hoved 7, og som samvirker med et gevind i tværstykket 4 eller eventuelt med et derpå anbragt endestykke af metal med gevind. Endvidere har fastgørelsesorganet en hoveddel 6, hvori skruehovedet 7 er forsænket, og som er forbundet med tværstykket 4 ved hjælp af tynde bøjelige strimler 8, 8', som er indrettede til at bøje ud ved deres midterparti, når tværstykket 4 og hoveddelen 6 bevæges i retning mod hinanden ved spænding af skruen 5- 3 146978The fastener of the drawing comprises a crosspiece 4, a screw 5, which is provided with a head 7 and which cooperates with a thread in the crosspiece 4 or, optionally, with a threaded metal end piece arranged thereon. Further, the fastener has a head portion 6 in which the screw head 7 is recessed and which is connected to the crosspiece 4 by means of thin flexible strips 8, 8 'which are adapted to bend at their central portion as the crosspiece 4 and the body portion 6 are moved in towards each other by tightening the screw 5- 3 146978

Tværstykket 4 og strimlerne 8, 8' har en sådan bredde, at de kan passere frit gennem de slidsformede åbninger la og 2a i henholdsvis vaskekummen 1 og konsollen 2. Længden af tværstykket 4 og hoveddelen 6 er imidlertid tilstrækkelig til at spænde over de respektive slidsåbninger i den på fig. 2 og 3 viste stilling. Som det navnlig fremgår af fig. 3, er de fleksible strimler 8, 8’ bøjede frit ud i den slidsformede åbning la i vaskekummen uden at komme i berøring med denne. Når fastgørelsesorganet er spændt, som vist på fig. 3, har disse strimmeldele 8, 8' tjent deres formål og er uden betydning for den permanente forankring af vaskekummen 1 til konsollen 2 ved hjælp af fastgørelsesorganet.The crosspiece 4 and the strips 8, 8 'have a width such that they can pass freely through the slotted apertures 1a and 2a in the wash basin 1 and the bracket 2. However, the length of the crosspiece 4 and the body part 6 is sufficient to span the respective slit openings. in the embodiment of FIG. 2 and 3. As can be seen in particular from FIG. 3, the flexible strips 8, 8 'are bent freely into the slotted aperture 1a of the wash basin without contacting it. When the fastener is tightened, as shown in FIG. 3, these strip portions 8, 8 'have served their purpose and are of no importance to the permanent anchoring of the wash basin 1 to the bracket 2 by means of the fastening means.

Som det navnlig fremgår af fig. 1, har hoveddelen 6 en aftrapning, således som vist ved 9, således at dette aftrappede parti kan indtræde i slidsåbningen 2a i vaskekummen 2 og forhindre drejning af fastgørelsesorganet ved spænding af skruen 5-As can be seen in particular from FIG. 1, the main part 6 has a step-up, as shown at 9, so that this step-up portion can enter the slot 2a in the wash basin 2 and prevent rotation of the fastener by tightening the screw 5-

Der er i den viste udførelsesform anvendt to fleksible strimler 8, 8’, men de.t vil forstås, at den beskrevne funktion også vil kunne opnås med en enkelt sådan strimmel til at forbinde tværstykket med hoveddelen af fastgørelsesorganet.In the illustrated embodiment, two flexible strips 8, 8 'are used, but it will be appreciated that the described function can also be achieved with a single such strip to connect the crosspiece to the body of the fastener.

Ved den viste udførelsesform er der gået ud fra, at tværstykket 4, strimlerne 8, 8' og hoveddelen 6 er fremstillet ud i ét stykke af formstof. En særlig interessant variant af fastgørelsesorganet består i, at tværstykket dannes af en metaldel, fortrinsvis af stål, med kanalformet tværsnit. Ved denne udformning vil det være let at opnå tilstrækkelig styrke af tværstykket. Et tværstykke af stål vil naturligvis også være forsynet med et gevindhul for spændeskruen. De øvrige dele af organet, nemlig strimlen henholdsvis strimlerne og hoveddelen, kan i dette tilfælde være støbt ud i ét stykke af formstof. Det er i så tilfælde ikke nødvendigt med særlige foranstaltninger til montering af tværstykket på organet, idet dette uden videre opnås ved hjælp af spændeskruen.In the embodiment shown, it is assumed that the crosspiece 4, the strips 8, 8 'and the body part 6 are made of one piece of resin. A particularly interesting variant of the fastener is that the crosspiece is formed of a metal part, preferably of steel, with channel-shaped cross section. In this design, it will be easy to obtain sufficient strength of the crosspiece. Of course, a steel cross piece will also be provided with a threaded hole for the clamping screw. The other parts of the body, namely the strip and the strips and the main part, may in this case be molded into one piece of plastic material. In that case, no special measures are required for mounting the crosspiece on the member, as this is easily achieved by means of the clamping screw.
