Definitions
- the invention relates to a lid with an inner part, in particular for an oil container, wherein the inner part has locking elements for interacting with a bayonet cam of the container to be closed and the inner part can be pressed onto the bayonet cam under spring tension.
- Lids of this type which result in a cut by the bayonet connection, are known for numerous applications. This applies e.g. for oil tanks, for the cooling water tank of a motor vehicle and the like.
- An inner part arranged in the interior of the lid, in which locking elements are molded, is placed on the container to be sealed.
- the locking elements are guided on the bayonet cam track of the container and are generally locked after a quarter turn.
- a spring ensures that the locking elements are pretensioned or securely guided and the lid is clamped onto the container. With an additional seal, a seal can be achieved, possibly with a vent hole.
- Known covers consist of several parts, namely the actual cover, the inner part with the locking elements and a spring, generally a helical spring, for generating the desired pretension.
- the lid usually has an inwardly drawn part, which as Counter bearing for the coil spring is used.
- the sheet metal part with the locking elements is designed as a rigid element, the spring had the task of compensating for tolerances in addition to prestressing and sealing the cover.
- the present invention has for its object to provide a lid of the type mentioned, which is simple and cheap to manufacture, i.e. which is particularly suitable for series production and which closes well.
- the inner part has a base plate with fastening elements for fastening to the lid, and that elastic arms extend from the base plate and the locking elements are arranged on the outer free ends thereof.
- the inner part practically consists of only a single element, namely the base plate, on which the fastening elements and the locking elements are arranged via elastic arms.
- the elastic arms with the locking elements thus replace the spring.
- the cantilevered arms which act like a cantilevered support, achieve a spring action and also tolerance compensation during the closing of the cover, ie while the locking elements are being guided on the cam tracks.
- a simple embodiment of the invention can consist in that the arms project freely from the base plate in an arcuate manner. go. Two arms can be arranged opposite one another.
- the course of the bends or their free ends are adapted to the inner wall of the container so that the locking elements can be guided accordingly on the bayonet cam track.
- the attachment of the inner part with the lid itself can be done in any way.
- a simple, but very effective attachment is that the base plate in the central inner region has an opening into which a central pin of the cover protrudes, and that the fastening members attack the central pin.
- Knobs, cams or the like can be used as fastening elements. be used, e.g. in recesses, undercuts or the like. inserted or clamped in the center pin.
- the central pin has a rectangular cross section.
- the base plate also has a correspondingly adapted rectangular recess.
- the inner part can be produced in a simple and very 'cheap way when the base plate with the Befest Trentsglie ⁇ countries, the poor and the latch el ementen from a blank of spring steel is punched.
- the inner part can be punched out practically in one operation, after which it is only necessary to bend the fastening elements and / or the locking elements.
- a plastic can of course also be used within the scope of the invention, it being only necessary for the plastic to have elastic properties.
- each arm is provided with two cams, which are arranged opposite one another at an end of the arms.
- Fig. 1 a plan view of an inner part
- Fig. 3 a reduced view of a cover with an inner part according to the invention in longitudinal section
- a cover 1 with a collar 2 has in its central area a central pin 3 which has a square shape in cross section and which is slightly conical at least in the area of its free end.
- the lid is provided with a seal 4 which is pressed onto the top of a container 5.
- the container 5 has in a known manner an obliquely ending bayonet cam 6, which at the end merges into a horizontal 7 with an end stop. A defined closed position is created by the horizontal 7 and the end stop, the cover simultaneously reaching a latching position.
- the inner part of the lid can be seen in more detail. It consists of a base plate 8 with an opening 9 in the central inner area. Starting from the base plate 8 are two opposing arcuate arms 10 and 11, each of which has an angled portion 12 and 13 or angled portions at its free outer ends.
- Cams 14 each project downward from the offsets 12 and 13, respectively.
- the cams 14 serve as locking elements and are 5 in when closing the container or guided on the bayonet cam track 6.
- tabs 15 are bent at least approximately obliquely downwards, evenly distributed over the circumference.
- the inner part consists of a single element, e.g. a spring steel plate. From this Plati ⁇ ne, in which the opening 9 and slots 15 are punched to separate the arms 10 and 11 from the base plate, the tabs 15 and the locking elements 14 were bent down from the flat surface.
- the inner part can be easily connected to the cover 1 after its manufacture. For this it is only necessary to slide the base plate 8 onto the central pin 3 from below. If there is e.g. the base plate made of a harder material such as the central pin 3, which is preferably in one piece with the cover 1, the tabs 15, which are elastic, can grip or clamp in the central pin 3. In this way, a secure connection is guaranteed.
- the cover 1 is placed on the neck of the container 5, the locking elements 14 being inserted into the bayonet cam 6 of the container 5. With a slight rotation of the cover 1, the locking then takes place in the usual manner, a separate spring being omitted due to the elasticity or the leaf spring-like configuration of the two arms 10 and 11.
- a vent slot 17 can be provided in the lid 1 to vent the container.
