Description

» -1- * MECHANISCHE VERBINDING, o.a. ten behoeve van kunststof buttons.»-1- * MECHANICAL CONNECTION, for example for plastic buttons.

Deze uitvinding betreft de verbinding van een dopachtige bovenplaat met een sluitplaat.This invention relates to the connection of a cap-like top plate with a closing plate.

Beide van een harde kunststof en geproduceerd d.m.v. een massa-produktieproces, zoals spuit--5 gieten en gebruikt kan worden als identificatie-drager of button.Both made of a hard plastic and produced by means of a mass production process, such as injection molding and can be used as an identification carrier or button.

Een mogelijk element is bekend uit een franse publikatie: FR/A/1512473.A possible element is known from a French publication: FR / A / 1512473.

Hierbij worden twee delen met kracht in elkaar 10 gedrukt.Two parts are hereby pressed together with force.

Ook is het bekend kunststofdelen te bevestigen door uitstekende randen, waarachter het onderdeel vastgehouden wordt.It is also known to fix plastic parts by protruding edges behind which the part is held.

Deze produktiemethode heeft het nadeel dat 15 ,,click-in,,-randen, i.v.m. het lossen uit de matrijs, niet toepasbaar zijn bij harde kunststoffen.This production method has the disadvantage that 15 click-in edges, in connection with unloading from the mold, not applicable for hard plastics.

Ook heeft harde kunststof weinig elasticiteit, waardoor het verende deel voor 20 de "click-in^?-verbinding of erg kwetsbaar wordt of niet tot nauwelijks realiseerbaar is.Hard plastic also has little elasticity, as a result of which the resilient part for the "click-in connection" either becomes very fragile or can hardly be realized.

Normaliter heeft een klik-verbinding het nadeel dat het vast te houden onderdeel enige vrijheid van beweging heeft.Normally, a click connection has the disadvantage that the part to be held has some freedom of movement.

25 De mechanische verbinding wordt als volgt omschreveni .* Λ “' λ Ü / y u / £ 3 -2- \ -2- s25 The mechanical connection is described as follows. * Λ “'λ Ü / y u / £ 3 -2- \ -2- s

Figuur 1 geeft de samenstelling, figuur 2 de sluitplaat en figuur 3 de bovenplaat weer.Figure 1 shows the composition, figure 2 the closing plate and figure 3 the top plate.

De sluitplaat (1) is voorzien van een 5 aantal bobbeltjes (2) op de omtrek.The closing plate (1) is provided with a number of bumps (2) on the circumference.

De maat over de bobbeltjes (2) is iets groter dan de ontvangende uitsparing (3) in de bovenplaat (4).The size over the bumps (2) is slightly larger than the receiving recess (3) in the top plate (4).

Deze uitsparing (3) in de bovenplaat (4) . 10 is op het cylindrisch gedeelte (5) van een geruwd oppervlak voorzien, bij voorkeur d.m.v. een vonkerosie.This recess (3) in the top plate (4). 10 has a roughened surface on the cylindrical portion (5), preferably by means of a spark erosion.

Zodra de sluitplaat (1) in de bovenplaat (4) wordt geperst gebeurt het volgende.As soon as the strike plate (1) is pressed into the top plate (4), the following happens.

15 Door de hoge oppervlaktedruk van de bobbeltjes (2) ontstaat er een deformatie van de bobbeltjes (2), waarbij de maat over de bobbeltjes (2) zich aanpast. Deze maataanpassing verzorgt een perspassing tussen de bobbeltjes (2) en de ruwe vonkstructuur 20 van de wand (5).Due to the high surface pressure of the bumps (2), a deformation of the bumps (2) is created, whereby the size over the bumps (2) adjusts. This size adjustment provides a press fit between the bumps (2) and the rough spark structure 20 of the wall (5).

Hierdoor ontstaat een relatief sterke verbinding, die mede afhankelijk is van het aantal bobbeltjes (2).This creates a relatively strong connection, which partly depends on the number of bumps (2).

De verbinding verhindert het verdraaien van de sluitplaat (1) binnen de bovenplaat (4).The connection prevents the closing plate (1) from twisting inside the top plate (4).

25 De sluitplaat (1) kan voorzien zijn van sleuven (6) waarmede b.v. een veiligheidsspeld mede bevestigd kan worden.The closing plate (1) can be provided with slots (6) with which e.g. a safety pin can also be attached.

Tussen bovenplaat (4) en sluitplaat (1) kan een tussenliggend element (7) opgesloten worden.An intermediate element (7) can be enclosed between top plate (4) and closing plate (1).

De mechanische verbinding is niet alleen 5 voorbehouden aan ronde elementen.The mechanical connection is not only reserved for round elements.
