The subject of the invention is a one-piece plastic ^ j || Ä ', with a tendon effect when swiveling the »Beekeltei les, caused by a bulge is tfeokelteil, whereby the tendon effect is an automatic locking of the Lid lid in the open position and helmet closing gate also an automatic locking of the deodorant part eggs plastic boxes.

A plastic box (DBGM 1 932 760), in which the base part and the Beokel part is made with a resilient articulation in one unit. The characteristics of this resilient articulated connection between the cover part and the bottom part consists in that at least three joint sections arranged side by side, but separated from one another by a gap, form the resilient joint connection, the joint line of the central joint section in height and to the side opposite the two Joint lines of the sweeter Geleakabsohnitte is arranged offset. Surahs the Mutual Joint! Inien-Versat " a spring effect arises when the joint halves are bent dee Mittleren Gelenjfcafesehaitte «to the two outer ge * lenkabsehnitten and is thereby the cover part respectively in the hold-open position and la in the hold-open position animals,

This one-piece plastic box with spring hinge connection has the special feature that, due to the open separation gap between the individual hinge parts, the plastic box is always leaky at these points.

Furthermore, a construction for a hinge-like joint made in one piece has become known at

we lohe «! the joint axis of the oil groove over the whole Length is arcuately curved »

This construction, however, has not proven itself in practice, since w the joint halves can bend "α, the curved joint groove very much!" to dissolve opposing tensile forces of the outer area to the middle area of the joint groove. After a short period of actuation, the joint groove tears in this joint ion construction in the respective outer area, making the joint unusable.

The invention is based on the object ie Injection molding produced Seanappgelenfc-Yerbinduiig with opening and closing effect between the Deekel part and the lower part of a one-piece © », but tight plastic box to aehaffeiu

According to the invention, this object is achieved in that, when viewed in the closed position, a positive roof-shaped bulge is inserted into the lid part of the plastic box *, which is raised in the lid surface, and when the lid part is opened, the positive roof front plunges into an opposing negative roof shape. The turning point is stuck in the open position and then reversed in turn when it is closed. The pivot point for the Deekelteil is / executed along de "upper% mA of Bfiokwand of üaterteilea and thereby the cover part with three side parts, '"' The inserted Daehfor "i" öeckelteil consists - seen in the closed position - of a rigid, relatively-thick triangular back side of the plastic box, which forms the gable wall in the area of the positive daehfor "and made of two inclined triangular" oaehilachen, made of relatively thin material "that slope from the ridge line to the left and right, with the outer ends of the roof surfaces and the piret line in The transition from the two triangular, thin roof surfaces to the top surface is via a slightly shaped

Geienkriile * The firet line of the left and right roof flanks is also a slightly outer joint groove, the transition from the relatively thick gable wall on the sloping roof to the two triangular thin roof surfaces consists of a strongly shaped joint groove, the two sweeter joint grooves between the cover surface and the Btickwand the lower part outside the gable wall have a common zusasaienfluchtende joint line and this joint grooves are also strongly ausgeforiat the Seienklinie the articulation of üqu two roof slopes between the roofs and the öiebelwaad running Troubles "si # at straight flight, but each to angled towards the middle area, corresponding to the slope of the gable wall. The entire line between the lid part and the lower part runs there-bit - seen from left to right - first in a straight line, then at an angle to the ridge point, then sloping in the opposite direction bia back into a straight line,

In the middle area of the angled oil groove opposite the two outer areas of the joint groove, there is a sons-lapping effect in the closed position of the lid part in the closed position compared to the open division in the thin roof surfaces of the roof-shaped exterior of the lid part of the iCunetatoff box The "one joint half of the thick gable wall of the lower part *" between the open * and closed position maintains the shape in the plane, while the other half of the joint of the thin, associated part of the joint has the turning point τοη A ^ r Offea »tell» ng in the closed position and vice versa, corresponding to the angular height U0T roof shape and the angle of the gable wall along the ridge line. Preferably, the roof surfaces of the ceiling part, starting from the ridge point, are wavy 1 »spacing» with slightly pronounced grooves, so that the thin roof * 1 »otherwise thicker bevel part above the angled hinge line is flexible compared to the rigid, thick gable wall of the lower part b

the angled »joint line. As a result, the heavily shaped gel groove maintains the angular alignment during the angle of the joint half from the open position into the closed position and, vice versa, without the joint groove becoming jammed in one another angle of the gable wall la connection asur angular position of the lid Teilee in the open division determines the Endateilung de "cover Teilee ^ 4The plastic boxes home Close sYou Schlieüstellung 1st erreiokt when the Trenaflache of Deekelteiles rests on the frennfläohe dee lower part.

The plastic box is each made in the open position in one piece by injection molding.

In some other applications, it is not desirable for the cover part to be locked, as mentioned above, by the tension force, but rather for a special locking device to take place. In these "cases Eiidetellung the lid 1st part it in * SchUeßvergang by the Sehnappeffekt already v r de" Errei marriages de?

of the turning point · swiveled back into the Offeasteliung and there automatically locked by the Mngesehnappen · Sachtorm.

In some other applications, however, it is desirable that the locking of the bevel part is also carried out by a special locking device, but after the locking device has been opened, the locking part jumps into the usage-open part, which is 80 degrees, for example. Since an injection-molded plastic box could not be injected into a one-piece "plastic box even with a difficult viewing eye" in this open position, this "case dl" plastic box is used with an eo. End of the automatic closing path of the lid surface, which then sprays the brewing-open division. For injection molding, the positive bulge is then swiveled right over the turning point to the open position with a negative bulge in the open position on simple wines. In this wide-open state, the plastic box can be "manufactured using a simple injection molding tool". The spring effect of the lid part from the closed position to the open position after the release of the locking device takes place in this application also by balancing the tensile forces!

The possible position in the process of snying of the »corner part, whether ii b« r or under the The separation area of the lower part is determined by the angle of attack the triangular gable wall of the lower part ssu causes the desired open position angle of the öeckelfläohe.

Furthermore, the strongly pronounced, angled joint groove and the joint groove of the ridge line can be widened i * the area of the apex _t ditfuit see the development of the joint halves at the turning point so that tensile forces can easily dissolve within this widened area of the joint groove.

Is can be converted into the plastic box * a for the various Yerweudungsaweoke are produced.

In the injection molding process, brackets, stops and other fixing hinges can be arranged inside or outside in the same production step without additional costs Characters, Nueuaera, Symbols, Scarring and ObtrJlU-cheneffekten can be equipped.

In the case of relatively tall plastic boxes, the articulated connection can also be placed on the outside of the plastic box.

The tendon effect of the joint halves is not limited to a lid and a lower part of a plastic box, but also to all hinge-like eyes, flaps and similar parts that require an open position to be closed.

The characteristic is in each case of an application that one half of the joint is negative angularly due to the angled joint line in the open position and when this joint half is pivoted out of the open position into the viewing area at the turning point, a snap effect angles the negative bulge in this joint half in the opposite direction, while the other "joint half the rigid position in the open position and do the SehlieDstellung preserved"
