Definitions
- the invention relates to a method for manufacturing a closure part for vacuum cleaner filter bags from a cardboard cut, which is a base plate, a connected to it on one side along a fold line Cover plate and one on the opposite Side with the base plate along another fold line has connected intermediate plate, initially the intermediate plate and then the cover plate the base plate are unfolded, after which in the Base plate and the cover plate through openings for the air outlet are congruent with each other and in between an externally operable locking slide can be inserted, initially in one piece with the cardboard cut is.
- Such a manufacturing method for the closure part a vacuum cleaner filter bag is from DE-C-42 17 544 known.
- the one there, as a rotary valve trained slide valve consists of the between the base plate and the cover plate to be folded in, the one piece over a connection area sits on the base plate. After folding of the closure part forms this connection area a target deformation or breaking point when twisting the rotary valve between its position of use and the shut-off position, which presupposes that a corresponding Resistance when operating the rotary valve must be overcome. If the rotary valve tears off Base plate, there is a risk of it completely between the base plate and the cover plate.
- the connection point between deforms the rotary valve and the base plate is formed here necessarily a fault, which the base plate and pushes the cover plate apart.
- Closure part known for vacuum cleaner filter bags at which is designed as a rotary slide valve is a separately manufactured part.
- a closure device is in the post-published utility model DE-U-94 19 123 described.
- Such one Closure part can only be manufactured in the way that when assembling the boards of the cardboard cut the slide gate by means of a separate handling process between the base plate and the cover plate is inserted.
- closure part for vacuum cleaner filter bags also prepares from a single die cut problems because the shutter slide between the base plate and the cover plate with a free space a width that requires a slight displacement of the Lock slide allows for a safe Closing or opening the through openings in the Base plate and in the cover plate for the air intake is possible.
- closure parts provided they have a slide valve leading intermediate plate between the base plate and the cover plate were provided, the locking slide with one opposite the intermediate plate reduced thickness and run it if necessary equipped on one side with an easy-sliding coating.
- the invention has for its object a method to propose of the type mentioned at the beginning, according to which that made from a single die cut Closure part including the slide gate after folding the cardboard cut of the slide is largely made freely movable.
- Locking slide consists of part of the intermediate plate and in the folded position of the cardboard cut by a separating cut through the base plate and / or the cover plate from the intermediate plate in order to move it between the Base plate and the cover plate is separated.
- the invention further relates to a closure part according to claim 3.
- closure slide having the thickness of the intermediate plate through impressions in the base plate and / or the cover plate with a resulting offset the wall sections enclosed by the embossments sufficient freedom of movement to the outside between the base plate and the cover plate with an easily overcome inhibition between his Open position and its closed position related to the through openings to be pivoted for the air inlet.
- the slide valve be a rotary slide valve, which for Closing or opening the through openings in the base plate and in the cover plate from the outside is pivoted.
- the Punching line and the interface between the intermediate plate and Locking slide arranged so that the locking slide with sections not shifted against each other of the severed connecting bridge in the Open position with regard to the through openings in the base plate as well as the cover plate.
- the intermediate plate For securely fixing the slide as a rotary slide in a corresponding contour of the intermediate plate can be used a pivot bearing approach to the Rotary valve molded and limited by an arc is, the intermediate plate an associated negative contour has the pivot bearing approach along a Arc angle of more than 180 ° surrounds. So that the Pivot bearing approach in the direction of the level of the intermediate plate are not shifted out of their negative contour, the connection neck between the Pivot bearing approach and the rotary valve is designed that the required swivel angle of the rotary valve for opening and closing the air passage openings of the closure part is not impaired.
- the structure and the function of the closure part by the opening the connecting web between the slide and to avoid the intermediate plate one appropriately arranges the separation point of the slide gate and intermediate plate and the to this end congruent through holes in the Base plate and cover plate in one of the plate corners.
- Figure 1 shows the complete cardboard cut for the closure part of a vacuum cleaner filter bag, the middle part forming a base plate 1 which unfolded the other elements of the cardboard cut become.
- the base plate 1 has an approximately central one Through opening 2 in the area of a wall section 4, which is from the line of an impression 3 is surrounded. Opposite the level of the base plate 1, the wall section 4 is offset so that its Inside compared to the inside of the other parts the base plate 1 is recessed.
- a hinge-like fold line 5 follows the base plate 1 to a cover plate 6, which also has a through opening 7, which at the to Base plate 1 folded over cover plate 6 with their Through opening 2 is congruent.
- the through opening 7 is in the area one with its inside opposite the inside the remaining parts of the cover plate 6 are recessed Wall section 9 by an embossing 8th is formed.
- the base plate 1 and the cover plate match this 6 through holes 18 and 19 on, which in merged Align each other and the arrangement cruciform through opening 17 of the pivot bearing approach 16 of the rotary valve 11, how to release in particular Figure 3 takes.
- Figure 1 also shows two through holes 20 and 21 in the corner area of the base plate 1 and the cover plate 6, also in a folded arrangement of these plates are congruent with each other and the separation point 14 with the connecting web 15 between release the rotary valve 11 and the intermediate plate 10.
- the cover plate 6 is around folded line 5 folded onto intermediate plate 10, here also the one enclosed by the impression 8 Interior receives the rotary valve 11.
- intermediate plate 10 here also the one enclosed by the impression 8 Interior receives the rotary valve 11.
- spaced wall sections 4 and 9 of the base plate 1 and the cover plate 6 then has the thickness direction of Closure part seen the rotary valve 11 such sufficient movement that he around the turning approach 16 using the free space 12 in the intermediate plate 10 can be pivoted so that the together aligned air passage openings 2 and 7 closed in the base plate 1 and in the cover plate 6 can be.
