Plougmann & Vingtoft Patent bureau.____ · _ (64) Kasse af plast med dobbelte vægge.Plougmann & Vingtoft Patent bureau .____ · _ (64) Double-walled plastic box.
Opfindelsen angår en kasse af den art, som er beskrevet i krav l's indledning, og nærmere betegnet et arrangement til at aflukke mundingen af mellemrummet mellem de to vægdele af en dobbelt-væg i en sådan kasse.The invention relates to a box of the kind described in the preamble of claim 1, and more particularly to an arrangement for closing the mouth of the gap between the two wall parts of a double wall in such a box.
Det er hensigtsmæssigt at fremstille plastkasser med dobbelte vægge, fordi det giver gunstige styrkeegenskaber i forhold til vægten og materialeforbruget. I sidevæggene har man ved disse kasser udformet ån eller flere åbninger, der bl.a. har kunnet tjene som håndgreb ved løftning af kassen. Åbningen bliver da afgrænset opefter af en dobbeltvægget bjælke, som imidlertid kan virke ubehagelig, når den gribes med hånden. Man har derfor efter kassens støbning lukket mundingen mellem vægdelene ved hjælp af en særlig 1A1361 2 skinne, sqm er blevet fremstillet separat og påsat ved slutningen af kassefremstillingen. Man har da haft problemer med at opnå et sikkert fæste for denne skinne, samtidig med at fremstillingen har været arbejdskrævende og dermed fordyrende.It is appropriate to make double-walled plastic boxes because it provides favorable strength properties in relation to weight and material consumption. In the sidewalls, these boxes have formed rivers or more openings, which include. have been able to serve as a handle when lifting the box. The opening is then bounded upwards by a double-walled beam, which, however, may appear uncomfortable when gripped by hand. Therefore, after casting the box, the mouth has been closed between the wall parts by means of a special 1A1361 2 rail, the sqm has been manufactured separately and applied at the end of the box manufacture. Problems have been achieved in obtaining a secure attachment for this rail, while at the same time manufacturing has been labor intensive and thus expensive.
Hensigten med opfindelsen er at fjerne denne ulempe og at reducere fremstillingsomkostningerne for sådanne kasser. Ifølge opfindelsen kan dette opnås ved at udforme kassen i overensstemmelse med den kendetegnende del af krav 1. Da skinnen støbes i samme arbejdsgang som resten af kassen, bliver fremstillingen forenklet, og skinnen kan umiddelbart efter støbningen svinges på plads og fastholdes dér ved klemning.The object of the invention is to eliminate this disadvantage and to reduce the manufacturing cost of such boxes. According to the invention, this can be achieved by designing the box according to the characterizing part of claim 1. Since the rail is molded in the same workflow as the rest of the box, the fabrication is simplified and the rail can be swung into place immediately after casting and retained there by squeezing.
En udførelsesform for kassen ifølge opfindelsen er vist på tegningen, på hvilken fig. 1 viser en plastkasse ifølge opfindelsen set i perspektiv, medens fig. 2 viser en del af et snit efter linjen II-II i fig. 1.An embodiment of the box according to the invention is shown in the drawing, in which FIG. 1 is a perspective view of a plastic box according to the invention, while FIG. 2 shows a section of a section along line II-II in FIG. First
Den viste kasse har en rektangelformet bund 11, som bærer fire hjørnesøjler 12. Hjørnesøjlerne 12 er ved overkanten to og to forbundet med bjælker 13, som strækker sig langs kassens sider på en sådan måde, at der dannes en åbning 14 i hver kasseside. Ved hver åbning 14 strækker sig langs underkanten en lav sidevæg 15.The box shown has a rectangular base 11 which carries four corner columns 12. The corner columns 12 are connected at the top two and two by beams 13 which extend along the sides of the box in such a way that an opening 14 is formed in each box side. At each opening 14, a low side wall 15 extends along the lower edge.
Hjømesøjlerne 12, bjælkerne 13 og sidevæggene 15 er på kendt måde udformet med dobbelte vægge, idet rummet mellem de dobbelte vægge er lukket opadtil og har en åbning eller munding mellem vægdelene nedadtil. Medens mundingerne i hjørnesøjlerne 12 og i sidevæggene 15 kan være åbne, anvendes bjælkerne 13 til gribning af kassen, hvorfor deres mundinger 16 (fig. 2) må lukkes på en sådan måde, at der dannes en jævn kant.The main columns 12, the beams 13 and the side walls 15 are in known manner formed with double walls, the space between the double walls being closed upwards and having an opening or opening between the wall parts downwards. While the orifices in the corner columns 12 and in the side walls 15 may be open, the beams 13 are used for gripping the box, so that their orifices 16 (Fig. 2) must be closed in such a way as to form a smooth edge.
Kassen i eksemplet har en skinne 17, som fortrinsvis strækker sig langs hele undersiden af den pågældende bjælke 13 således, som detThe box of the example has a rail 17, which preferably extends along the entire underside of the particular beam 13 as
