Den foreliggende opfindelse angår et sikringselement for byggedele i en legetøjsbyggekasse, hvori byggedelene kan forbindes med hinanden ved hjælp af underskårne noter og ind i disse, passende tappe.The present invention relates to a securing element for building parts in a toy building box in which the building parts can be connected to each other by means of cut grooves and into these, appropriate pins.

Ved en kendt legetøjsbyggekasse, hvis byggedele kan forbindes med hinanden ved hjælp af underskårne noter og underskårne lister eller fremspring, er tolerancerne af disse forbindelsesmidler valgt således, at der opnås en prespasning, hvis friktion tillader at der optages mindre kræfter, som forløber i notens længderetning. Ved større kræfter strækker denne friktionsvirkning alene ikke til. Endvidere anvendes der ved denne kendte legetøjsbyggekasse også fx af aluminium ved strengpresning fremstillede profiler, hvis langsgående noter på grund af fremstillingsmåden har større tolerancer. Derved er det nødvendigt for at opnå stabile tværforbindelser med omstændelige låsninger og afstivninger, der vanskeliggør en modelopbygning og ofte ikke lader sig anbringe på grund af pladsmangel.In a known toy building box whose building parts can be connected to each other by means of cut grooves and cut strips or projections, the tolerances of these connecting means are chosen so as to obtain a press fit whose friction allows less forces to be absorbed extending in the longitudinal direction of the groove. . With greater forces, this friction effect alone does not extend. Furthermore, this well-known toy building box also uses, for example, aluminum profiles made of extruding, whose longitudinal notes have greater tolerances due to the method of manufacture. This makes it necessary to achieve stable cross-links with cumbersome locks and stiffeners that make it difficult to build a model and often cannot be placed due to lack of space.

Den opgave, der derfor ligger til grund for opfindelsen, er at tilvejebringe en mulighed for at forbindelserne også kan optage i længderetningen af noterne rettede kræfter.The object of the invention, therefore, is to provide an opportunity for the connections to absorb longitudinal forces of the directed notes.

I henhold til opfindelsen opnås dette ved, at sikringselementet består af to dele, hvor hver del har en i byggedelenes not indgribende liste, der delvis udfylder notprofilet og som i længderetningen har kileform og ved at de to dele er indrettet til ved sammenskydning at sættes fast i noten i byggedelen.In accordance with the invention, this is achieved by the fact that the securing element consists of two parts, each part having a list which is included in the groove's groove, which partially fills the groove profile and which has a longitudinal wedge shape and that the two parts are arranged to be fastened by means of a joint. in the note in the construction section.

Til fastsætning indlægges de to dele af sikringselementet i byggedelens underskårne not og listerne i de to dele forskydes mod hinanden idet deres smallere endeflader vendes mod hinanden. På grund af kileformen af listen opstår der derved en fastspænding af de to dele i den underskårne not i byggedelen, således at der opnås en fast klempasning. Sikringselementet tjener nu som anslag for en byggesten, som lader sig indføre med en forbindelsestap med let glidepasning i den langsgående not i byggedelen. Med endnu et bag denne byggesten fastgjort sikringselement er denne sikret mod forskydninger i alle retninger. Den kan således indstilles nøjagtigt på forudbestemt afstand også ved høje kræfter.For fixing, the two parts of the securing element are inserted into the cut groove of the building part and the moldings in the two parts are shifted towards each other as their narrower end faces are facing each other. Due to the wedge shape of the molding, there is thus a clamping of the two parts of the cut groove in the construction part, so that a fixed clamping fit is obtained. The securing element now serves as a stop for a building block, which can be inserted with a connecting pin with a slight sliding fit in the longitudinal groove in the construction part. With yet another securing element attached behind this building block, it is secured against displacements in all directions. It can thus be adjusted precisely at a predetermined distance even at high forces.

I henhold til en udformning ifølge opfindelsen kan den ene langside af listen være underskåret passende til noten og den anden plant udformet. De plane langsider af listen danner 2According to a design according to the invention, one long side of the molding may be cut to fit the groove and the other plant formed. The planar long sides of the list form 2

glidefladerne, medens der på grund af den underskårne langside af listen sker en fuldstændig udfyldning af notprofilet. Begge lister kompletterer således hinanden til et mod begge sider underskåret forbindelsesmiddel, således at der ud over fastklemningen også opstår en mod løsning sikret svalehaleforbindelse.the sliding surfaces, while due to the cut long side of the list a complete filling of the groove profile. Thus, both moldings complement each other to a bonding agent cut against both sides, so that in addition to the clamping, a solution tailor-made dovetail is formed.

I henhold til endnu en udformning ifølge opfindelsen kan listerne på deres tykkeste sted være noget smallere end lysvidden af noten i byggedelen på dens smalleste sted. Denne udformning muliggør at de to dele af sikringselementet kan indsættes fra ydersiden ind i den underskårne not af byggedelen. Den tidsrøvende indskubning fra enden af noten især ved meget lange byggedele er således ikke nødvendig. Sikringselementet kan endvidere også indsættes på et senere tidspunkt mellem to på afstand fra hinanden på et tidligere tidspunkt placerede byggesten.According to yet another embodiment of the invention, the moldings in their thickest place may be somewhat narrower than the light width of the groove in the building portion at its narrowest place. This design allows the two parts of the securing element to be inserted from the outside into the undercut groove of the construction part. Thus, the time-consuming push-in from the end of the note, especially for very long building parts, is not necessary. Furthermore, the securing element can also be inserted at a later time between two spaced apart at an earlier time building blocks.

I henhold til endnu en udformning ifølge opfindelsen kan hver del af sikringselementet have en mod yderfladen af byggedelen anliggende gribeplade. Den som indsætningsbegrænsning tjenende plade letter ved anlægget mod byggedelen håndteringen af sikringselementet.According to yet another embodiment of the invention, each portion of the securing element may have a gripping plate abutting the outer surface of the building portion. The insert serving plate as an insertion limiter facilitates the handling of the securing element at the plant towards the construction part.

Endelig kan. ifølge opfindelsen en del af sikringselementet være udformet som vinkel, hvor hver vinkeldel har en liste. Ved denne særlige udformning af sikringselementet kan også stødforbindelser mellem to byggedele sikres og yderligere afstøttes i vinkelstilling. Der kan således fremstilles meget stabile ramme-konstruktioner, fx til legetøjskøretøjer.Finally, can. According to the invention, a part of the securing element is designed as an angle, with each angle part having a list. In this particular design of the securing element, shock connections between two building parts can also be secured and further supported in angular position. Thus, very stable frame designs can be produced, for example for toy vehicles.

På tegningen er der vist udførelseseksempler på opfindelsen. På tegningen viser:Embodiments of the invention are shown in the drawing. In the drawing:

I en af fire underskårne, langsgående noter 1 i en af et rørformet strengpresset profil bestående byggedel 2 er to dele 3a,3b af et sikringselement 3 indsat på en sådan måde, at disses lister 4 fuldstændig optages i noten 1. Profilet af listen 4 udfylder kun notprofilet delvis og er yderligere i længderetningen udformet med kileform. Som indsætningsbegrænsning på den ene side og for på den anden side at opnå en bedre håndtering, er delene 3a,3b af sikringselementet forsynet med en plade 5, der ligger an mod yderfladen af byggedelen 2, hvilken plade 5 kan være riflet på yderfladen.In one of four undercut longitudinal grooves 1 in a building member 2 of a tubular extruded profile, two parts 3a, 3b of a securing element 3 are inserted in such a way that their moldings 4 are completely included in the groove 1. The profile of the list 4 fills in only the groove profile is partially and is further longitudinally shaped with wedge shape. As insertion restriction on the one hand and to obtain better handling on the other hand, the parts 3a, 3b of the securing element are provided with a plate 5 which abuts the outer surface of the building part 2, which plate 5 may be grooved on the outer surface.

De modstående og som glideflader tjenenfe plane langssider 6 af listerne 4 på de to dele har i længderetningen en tilspidsning på ca. 2°. Listerne 4 er dobbelt så lange .som pladerne 5r således at listerne 4 ved sammenskubning af pladerne 5 bliver overdækket inden for pladerne.The opposed and sliding surfaces serving longitudinal planes 6 of the moldings 4 of the two parts have a longitudinal taper of approx. 2 °. The moldings 4 are twice as long as the panels 5r so that the moldings 4 are covered within the panels by pushing the panels 5 together.

De fra hinanden vendte langsider 7 af listerne 4 er un-derskårne. Ved sammenskubning kompletterer de feo lister 4 dermed hinanden til et underskåret forbindelsesmiddel/ hvis ydre dimensioner lader sig forstørre med 15% i forhold til·notens 1 profil. Derved kan der opnås en stærk fastklemning, således at sikringselementet 3 uforskydeligt kan fastsættes på ethvert ønsket sted i noten 1 på byggedelen. For at kunne gennemføre indsætningen af delene 3a,3b ind i noten udefra er det tykkeste sted på den enkelte liste 4 noget mindre end lysvidden på det snævreste sted af den underskårne not 1 i byggedelen. Additionen af dette tykkeste sted med det svageste sted i den anden liste frembringer dog det til fastklemningen nødvendige overmål i forhold til notprofilet.The longitudinal sides 7 of the moldings 4 are cut apart. By pushing together, the feo moldings 4 thus complement each other into a cut-out connection medium / whose external dimensions can be enlarged by 15% in relation to the profile of the note. Thereby a strong clamping can be achieved so that the securing element 3 can be slidably fixed at any desired location in the groove 1 of the construction part. In order to be able to insert the parts 3a, 3b into the groove from the outside, the thickest place on the individual list 4 is somewhat smaller than the light width at the narrowest place of the cut groove 1 in the construction part. However, the addition of this thickest spot with the weakest spot in the second list produces the excess clamping needed for the groove profile.

Fig. 2 viser anvendelsesmuligheder for sikringselementet 3 ifølge opfindelsen. Til hjørneforbindelser anvendes et sikringselement, hvor en del 3c af sikringselementet 3' er udformet som en vinkel og hvor hvert vinkelben har en liste 4. Til fastklemning af de to byggedele 2, som danner en hjørneforbindelse, sættes der på hvert ben af vinklen en yderligere del 3b, således at der på grund af de overlappende lister 4 dannes forbindelser mellem sikringselementet 3' og byggedelen 2. I den langsgående not 1 af en byggedel 2 er der med glidepasning indsat et med en underskåren forbindelsestap 8 udformet byggedel 9 til anlæg mod vinkelsikringselementet 3'. Til fastgørelse af dette fastklemmes der bag denne byggesten 9 endnu et sikringselement 3. Derved fremkommer der en nøjagtig afstandsfiksering, der også kan holde stand mod høje kræfter.FIG. 2 shows applications for the fuse element 3 according to the invention. For corner joints, a securing element is used, where a portion 3c of the securing element 3 'is formed as an angle and each angular leg has a strip 4. For clamping of the two building parts 2 which form a corner connection, an additional leg is added to each leg of the angle. part 3b, so that, due to the overlapping moldings 4, connections are formed between the securing element 3 'and the building part 2. In the longitudinal groove 1 of a building part 2, a building part 9 designed for abutting against the angle securing element is inserted with a sliding fitting tab 8. 3 '. To secure this, a further securing element 3 is clamped behind this building block 9, thus providing an accurate distance fixing that can also withstand high forces.
