OPASTEKILPIJARJESTELMA JA OPASTETAULU SKYLTSYSTEM OCH SKYLTSTALLNINGSIGNS AND SIGNS SKYLTSYSTEM OCH SKYLTSTALLNING

Keksinnon kohteena on opastekilpijarjestelma, jossa opaste-kilvet sijoitetaan paikoilleen opastetauluun niille tarkoi-tettuihin uriin ja johon jSrjestelmåån kuuluu runkolevyyn kiinnitetty valilista. Keksinto kohdistuu myos menetelmaan 5 opastetaulun muodostamiseksi, johon opastetauluun kuuluu suorakulmainen runkolevy, runkolevya ymparoiva kehyslista, ainakin yksi runkolevyyn kiinnitettava kiinnityslista ja ainakin yksi suorakulmainen, opastetaulun kokoa pienempi opastekilpi, joka asetetaan paikoilleen kehyslistan ja/tai 10 kiinnityslistojen uriin niin, etta opastekilpi tulee urien vSlityksella tuetuksi ainakin kahdelta reunaltaan. Lisaksi keksinto kohdistuu opastekilpijarjestelman kiinnityslis-taan, jonka yla- ja alaosaan on muodostettu urat opastekilpia vårten, ja kehyslistaan, johon on muodostettu kiinni-15 tyskohta kulmakappaletta vårten.The invention relates to a signboard system, in which the signboards are placed in place in the grooves intended for them on the signboard and which includes a selection strip attached to the base plate. The invention also relates to a method 5 for forming a signboard, the signboard comprising a rectangular frame plate, a frame strip surrounding the frame plate, at least one mounting strip to be attached to the frame plate and at least one rectangular signboard smaller than the size of the signboard supported on at least two edges. In addition, the invention relates to a mounting strip for a signboard system, the upper and lower parts of which have grooves formed on the signposts, and a frame strip, in which an attachment point is formed for the corner piece.

Opastekilvet rakennetaan tavallisesti kayttotarkoituksensa mukaan tarvittavan kokoisiksi ja -muotoisiksi. Talloin kilpien uusiminen on erittSin hankalaa, koska kilvet ovat erikokoisia ja muutostyot joudutaan tekemaan kalliisti 20 yksilollisena mittatilaustyona. Sen vuoksi opastekilpia on pyritty standardisoimaan niin, etta kilpia ei olisi kovin monia eri kokoja. Tasta kuitenkin seuraa se epakohta, etta jarjestelma on jaykka. Portaattain suurenevat kilvet ovat usein joko liian pienia tai liian suuria. Sopivaa kokoa ja 25 muotoa ei tailoin loydy helposti. Joustavia kilpijarjes- telmia onkin pyritty tekemaan monin eri tavoin, mutta kovin hyvin siina ei ole onnistuttu.Signs are usually constructed to the required size and shape according to their intended use. In that case, it is very difficult to renew the plates, because the plates are of different sizes and modifications have to be done costly in 20 individual custom-made orders. Therefore, efforts have been made to standardize signboards so that there are not very many different sizes of signs. However, this is followed by the drawback that the system is rigid. Gradually increasing signs are often either too small or too large. The right size and 25 shapes are not easy to find. There have been many attempts to make flexible shield systems, but it has not been very successful.

Erilaisista vakio-osista muodostettuja opastetaulujarjes-telmia on esitetty esimerkiksi US-patenteissa 2 632 271 ja 30 4 138 787. Kummassakin on taulun rakenne muodostettu modu- leista, jotka maaraavat kaytettavan kilpikoon. Opastekilpia paikallaan pitavat kannattimet ovat monimutkaisia ja kiin-nityksessa on kaytetty hankalia rakaisuja, kuten esimerkiksi maaratyin vaiimatkoin sijoitettuja lohenpyrstoliitoksia.Signage systems formed from various standard parts are disclosed, for example, in U.S. Patents 2,632,271 and 30,438,787. The brackets holding the signage in place are complicated and cumbersome dowels have been used in the fastening, such as dovetail joints placed at defined distances.

2 90696 TSmån keksinnon tarkoituksena on poistaa edella esitetyt ongelmat ja aikaansaada uusi opastetaulujarjestelmå, jolla ei ole tunnettujen jarjestelmien epåkohtia.The object of the present invention is to eliminate the above-mentioned problems and to provide a new signboard system which does not have the drawbacks of known systems.

Opastekilpien alareunat nojaavat alapuo-lella olevan kehyslistan uriin, kuten on esitetty kuvioissa 2 ja 6. Vastaavasti kiinnityslistojen 20 ja 21 ylapuolella 5 olevat opastekilvet 26 ja 27 nojaavat kiinnityslistojen ylapuolella oleviin uriin 33. Rakenteen poikkileikkaus on tarkemmin esitetty viela kuviossa 6.Figure 3 shows a partial enlargement of the structure of the central part of the signboard 10. The figure shows a frame plate 23, on both sides of which fastening strips 20 and 1: 5 90696 21 are fastened, the grooves 34 of which lock in place the upper edges of the signposts 24 and 25. The lower edges of the sign plates abut the grooves of the frame strip below, as shown in Figures 2 and 6. The sign plates 26 and 27 above the mounting strips 20 and 21, respectively, rest on the grooves 33 above the mounting strips. The cross-section of the structure is shown in more detail in Figure 6.

Kuviossa 4 on esitetty opastetaulun kehyslistan 13 poikkileikkaus. Kuviosta nahdaan aukko 15, joka on mitoitettu 10 kehyslistoja toisiinsa sitovien kulmapalojen mukaan. Kehys-listaan 13 on muodostettu kolme uraa, joista keskimmainen on runkolevyn ura 30. Taman molemmin puolin on symmetrisesti matalammat ja kapeammat urat 31 ja 32, jotka on mitoitettu opastekilpia vårten. Urien kaytto on selostettu 15 tarkemmin kuviossa 6.Figure 4 shows a cross-section of the frame strip 13 of the signboard. The figure shows an opening 15 dimensioned according to the corner pieces which bind the frame strips 10 together. Three grooves are formed in the frame strip 13, the middle of which is the groove 30 of the frame plate. On both sides of this there are symmetrically lower and narrower grooves 31 and 32 dimensioned relative to the signposts. The use of the grooves is described in more detail in Figure 6.

Kuviossa 5 on esitetty kiinnityslista 21, joka kiinnitetaan runkolevyyn halutulle korkeudelle. Kiinnityslistan 21 ala-puolella on opastekilven ura 34 ja vastaavasti ylapuolellla samanlainen ura 33. Kiinnityslistan 21 kiinnittåmiseksi 20 runkolevyyn on siihen mudostettu uloke 35, joka sopii runkolevyyn jyrsittavaan uraan. Jyrsinta voidaan tehda ohjelmoitavalla jyrsinkoneella. Kiinnityslistan 21 kiinni-tys runkolevyyn on tarkemmin esitetty kuviossa 6.Figure 5 shows a fastening strip 21 which is fastened to the base plate at the desired height. There is a groove 34 on the underside of the mounting strip 21 and a similar groove 33 on the upper side, respectively. To attach the mounting strip 21 to the body plate 20, a protrusion 35 is formed therein, which fits into a groove to be milled in the body plate. Milling can be done with a programmable milling machine. The attachment of the mounting strip 21 to the base plate is shown in more detail in Fig. 6.

Kuviossa 6 on esitetty poikkileikkaus keksinnon mukaisen 25 opastetaulun 10 alaosasta. Kuviosta nahdaan opastetaulun alareunassa oleva kehyslista 13, jonka sisalla on aukko 15 kokoonpanossa tarvittavia kulmapaloja vårten. Kehyslistan 13 ylapinnalla on kolme uraa, joista keskimmainen ura 30 on tarkoitettu runkolevyå 23 vårten. Runkolevyyn 23 kiinnite-30 taån kiinnityslistat 20 ja 21 halutulle korkeudelle kaytet-tåvien opastekilpien 24 ja 25 korkeuden mukaan. Kiinnityslistat 20 ja 21 kiinnitetaan siten, etta runkolevyyn 23 jyrsitaan uloketta 35 vastaava ura, johon kiinnityslistan uloke 35 painetaan ja liimataan kiinni. Koska kiinnityslis-35 toille 20 ja 21 ei ole mitaSn ennalta maarattya paikkaa, 6 90696 voidaan niiden sijainti valita vapaasti. Tasta seuraa se, etta opastejårjestelmåsså kaikkien opastekilpien korkeudet voidaan valita portaattomasti halutun korkuisiksi.Figure 6 shows a cross-section of the lower part of the sign board 10 according to the invention. The figure shows a frame strip 13 at the bottom of the signboard, which has an opening 15 for the corner pieces required in the assembly. The upper surface of the frame strip 13 has three grooves, of which the middle groove 30 is intended for the frame plate 23. Attach the mounting strips 20 and 21 to the base plate 23 to the desired height according to the height of the signs 24 and 25 to be used. The fixing strips 20 and 21 are fixed in such a way that a groove corresponding to the projection 35 is milled into the body plate 23, into which the projection 35 of the fixing strip is pressed and glued. Since there is no predetermined location for the mounting attachments 35 and 21, their location can be chosen freely. It follows that in the signage system, the heights of all signage signs can be selected steplessly to the desired height.

Runkolevyyn 23 kiinnitettyjen kiinnityslistojen 20 ja 21 5 alaspain avautuvat urat 34 muodostavat opastekilpien 24 ja 25 ylareunojen lukituksen. Vastaavasti nåiden kiinnityslistojen ylapinnalla on samanlaiset urat 33, joiden påålle voidaan sijoittaa toiset opastekilvet 26 ja 27, jotka taas ylareunastaan lukitaan samanlaisilla kiinnityslistoilla tai 10 ylåreunan kehyslistalla.The depressing grooves 34 of the fastening strips 20 and 21 5 fixed to the body plate 23 form a locking of the upper edges of the signage plates 24 and 25. Correspondingly, the upper surface of these fastening strips has similar grooves 33, on top of which other signage plates 26 and 27 can be placed, which in turn are locked at their upper edge by similar fastening strips or at the upper edge frame frame.

Keksinndn mukainen opastetaulujarjestelmå, joka muodostuu runkolevystS 23, kehyslistoista 11, 12, 13 ja 14 ja kiinni-tyslistoista 21 ja 22, antaa mahdollisuuden rakentaa opas-tetaulusta lahes minka kokoisen ja muotoisen tahansa.The signboard system according to the invention, which consists of a base plate S 23, frame strips 11, 12, 13 and 14 and fastening strips 21 and 22, makes it possible to construct a signboard of almost any size and shape.

15 Jarjestelmassa tarvitaan ainoastaan kahta erilaista tanko-profiilia 13 ja 20 sekå yhdenlaisia kulmapaloja 16. Runko-levyn 23 ja kilpien 24 ja 25 koot voidaan valita vapaasti. Opastetaulussa 10 voi olla yksi tai useampi opastekilpi sijoitettuna ainoastaan taulun toiselle puolelle, mutta 20 myos taulun molenunilla puolilla voi olla tarvittava maarå opastekilpia.15 The system requires only two different bar profiles 13 and 20 as well as identical corner pieces 16. The sizes of the body plate 23 and the plates 24 and 25 can be freely chosen. The signboard 10 may have one or more signboards placed only on one side of the signboard, but 20 may also have the necessary number of signboards on both sides of the signboard.

Alan ammattiiniehelle on selvaa, etta keksinndn erilaiset sovellutusmuodot voivat vaihdella jSljempanS esitettavien patenttivaatimusten puitteissa.It will be apparent to those skilled in the art that various embodiments of the invention may vary within the scope of the appended claims.
