i DK 96 00160 U3in DK 96 00160 U3

Den foreliggende frembringelse angår en tegnelineal, navnlig til taylebrug, og af den i indledningen til krav 1 angivne art.The present invention relates to a drawing ruler, in particular for teal use, and of the kind specified in the preamble of claim 1.

Kendte tavlerekvisitter består almindeligvis af flere dele, nemlig plane emner med forskellig facon - f.eks. trekantede, hel- eller halvcirkulære, plane emner, samt linealer, hvorpå der er monteret udragende håndtag. En sådan konstruktion åbner mulighed for beskadigelser i form af brud mellem det plane emne og håndtag eller lokale trykskader af kanter og hjørner (spidser).Known painting props usually consist of several parts, namely planar items with different shapes - e.g. triangular, semi-circular, flat items, and rulers on which projecting handles are mounted. Such a construction allows for damage in the form of a break between the planar item and handles or local pressure damage of edges and corners (tips).

Frembringelsen har til formål at angive en forbedret tegnelineal af den i indledningen nævnte art, der kan oppebære ekstraordinær styrke, og som i forhold til kendte tavlerekvisitter i forsendelses- og brugssituationen har væsentlige fordele.The object of the invention is to provide an improved drawing ruler of the kind mentioned in the introduction, which can carry extraordinary strength and which has significant advantages over the known painting props in the shipping and use situation.

Tegnelinealen ifølge frembringelsen er kendetegnet ved, at håndgrebet består af fortrinsvis centrale udskæringer i linealen eller af plademateriale mellem nævnte udskæringer. På enkel måde opnås herved en tegnelineal, der kan oppebære ekstraordinær stor brudstyrke, og som har væsentlige fordele. Eksempelvis kan tegnelinealen, der kun består af én del, fremstilles med et reduceret materialeforbrug, der medfører en tilsvarende mindre egenvægt. Desuden har tegnelinealen ifølge frembringelsen bl.a. på grund af o dens rumlige opbygning en forbedret balance, der gør det nemmere at håndtere tegnelinealen. Da håndgrebet er en integreret del af linealen, opnås desuden, at denne kan stables tæt for lagerføring, forsendelse og senere opbevaring.The drawing ruler according to the invention is characterized in that the handle consists preferably of central cuts in the ruler or of sheet material between said cuts. In this way, a drawing ruler is obtained which can carry extraordinarily high breaking strength and which has significant advantages. For example, the drawing ruler, which consists of only one part, can be manufactured with a reduced material consumption, which results in a correspondingly smaller weight. In addition, according to the drawing, Due to its spatial structure, an improved balance makes it easier to handle the drawing ruler. Furthermore, since the handle is an integral part of the ruler, it can be stacked tightly for storage, shipping and later storage.

Hensigtsmæssigt er tegnelinealen ifølge frembringelsen således udformet, at håndgrebet består af to eller tre centrale udskæringer i linealen eller af plademateriale mellem nævnte udskæringer.Conveniently, the drawing ruler according to the invention is designed such that the handle consists of two or three central cuts in the ruler or of sheet material between said cuts.

I en foretrukken udførelsesform er tegnelinealen ifølge frembringelsen således udformet, at håndgrebet består af tre cirkulære huller eller af plademateriale mellem nævnte huller, der fortrinsvis er placeret på begge sider af en langsgående, central ryg af linealen.In a preferred embodiment, the drawing ruler according to the invention is designed such that the handle consists of three circular holes or of sheet material between said holes, which are preferably located on both sides of a longitudinal, central back of the ruler.

Alternativt kan tegnelinealen ifølge frembringelsen være således udformet, at håndgrebet består af radiale ribber af en tredelt, cirkulær udskæring, der strækker sig til begge sider af en langsgående, central ryg af linealen.Alternatively, the drawing ruler according to the invention may be designed such that the handle consists of radial ribs of a three-part circular cut extending to both sides of a longitudinal central back of the ruler.

Eller en yderligere alternativ tegnelineal ifølge frembringelsen kan være således udformet, at håndgrebet består af materialeribber mellem tre udskæringer, der tilsammen danner et centralt ovalt område af linealen, hvilket ovale område fortrinsvis strækker sig til begge sider af en langsgående, central ryg af linealen.Or, a further alternative drawing ruler according to the invention may be designed such that the handle consists of material ribs between three cuts forming a central oval region of the ruler, which oval region preferably extends to both sides of a longitudinal central ridge of the ruler.

Fortrinsvis er tegnetrekanten ifølge frembringelsen således udformet, at nævnte opadhvælvede midterste tværsnit har form som et omvendt V.Preferably, the drawing triangle according to the invention is designed such that said upwardly-vaulted middle cross-section is in the form of an inverted V.

Den i fig. 1 viste tegnelineal 2 er udformet med et centralt håndgreb 4, der består af tre radiale ribber 6 af en tredelt cirkulær udskæring 8, der strækker sig til begge sider for en langsgående ryg 10, idet tegnelinealen 2 har omvendt V-formet tværsnit og er fremstillet af et formstabilt plademateriale.The FIG. 1, the drawing ruler 2 is formed with a central handle 4 consisting of three radial ribs 6 of a three-part circular cut-out 8 extending to both sides of a longitudinal back 10, the drawing ruler 2 having the reverse V-shaped cross-section and being made of a mold-stable sheet material.

Den i fig. 2 viste tegnelineal 12 er udformet med et centralt håndgreb 14, der består af tre udskæringer 16 eller af materialet mellem disse udskæringer 16, der strækker sig over et centralt, ovalt felt til begge sider for en langsgående ryg 18, idet tegnelinealen 12 i lighed med linealen 2 jfr. fig. 1 har omvendt V-formet tværsnit og er fremstillet af et formstabilt plademateriale.The FIG. 2, the drawing ruler 12 is formed with a central handle 14 consisting of three cuts 16 or of the material between these cuts 16 extending over a central oval field on both sides for a longitudinal back 18, the drawing ruler 12 being similar to the rulers 2 cf. FIG. 1 has the inverse V-shaped cross-section and is made of a form-stable sheet material.

En foretrukken udførelsesform for en tegnelineal 20 er vist i fig. 3-5. Ved denne tegnelineal består et centralt håndgreb 22 of tre cirkulære huller 24 - eller måske rettere af pladematerialet derimellem. Håndgrebet 22 henholdsvis hullerne 24 er placeret til begge sider for en central, langsgående ryg 26, idet tegnelinealen 20 - som tydeligst vist i fig. 5 - har omvendt V-formet tværsnit.A preferred embodiment of a drawing ruler 20 is shown in FIG. 3-5. At this drawing ruler, a central handle 22 consists of three circular holes 24 - or perhaps rather, the sheet material therebetween. The handle 22 and the holes 24, respectively, are positioned on both sides for a central longitudinal back 26, the drawing ruler 20 - as most clearly shown in FIG. 5 - has inverted V-shaped cross section.

Tegnelinealen 2, 12, 20 ifølge opfindelsen er med andre ord udformet med et håndgreb 4, 14, 22 , der er udformet som en integreret del af selve pladematerialet, hvoraf tegnelinealen er fremstillet - det være sig ved sprøjtestøbning, ekstrudering eller bukning ud fra præfabrikerede pladeemner. Det med pladematerialet integrerede håndgreb 4, 14, 20 giver bl.a. tegnelinealen følgende fordele/egenskaber: Stabilt greb, god balance, ingen eftermontering af greb efter trykproces (målsætning), mere robust (ingen løse dele, der kan rykkes eller knækkes af), reduktion i materiale (vægt og pris), stabelbar (letter distribution og opbevaring).In other words, the drawing ruler 2, 12, 20 according to the invention is formed with a handle 4, 14, 22, which is formed as an integral part of the sheet material itself, of which the drawing ruler is made - be it by injection molding, extrusion or bending from prefabricated coils. The handles 4, 14, 20 integrated with the sheet material provide, inter alia, The drawing line has the following advantages / features: Stable grip, good balance, no retrofitting of grips after printing process (objective), more robust (no loose parts that can be torn or broken), reduction in material (weight and price), stackable (easier distribution and storage).

Navnlig den foretrukne udførelsesform for tegnelinealen 20 jfr. fig. 3-5 giver en ekstra god styring og balance ved både lodret og vandret anvendelse. Det skal påpeges, at antallet og faconen af håndgrebshulleme kan variere efter behov, og at de viste udførelsesformer for tegnelinealen ifølge frembringelsen naturligvis kan modificeres også i størrelse, idet tegnelinealen eksempelvis kan fremstilles i mindre udgaver til bordbrug.In particular, the preferred embodiment of the drawing ruler 20 cf. FIG. 3-5 provides extra good control and balance for both vertical and horizontal applications. It should be noted that the number and shape of the grip holes may vary as required and that the embodiments of the drawing ruler according to the invention can of course also be modified in size, for example the drawing ruler can be manufactured in smaller versions for table use.
