DE6928863U - CLOSURE FOR THE FILLER OPENING OF A PRESSURE PAINT SPRAYER - Google Patents

Description

"Sealed for the egg filling opening of a color pressure vessel

The innovation is aimed at a closure for the filler opening of color pressure vessels for spray equipment.

Such vessels usually have for the filling opening a screw cap or a clip lock. The closure cover is placed on the opening from the outside and neither held by a screw or by a bracket. The holding means, be it the screw connection - be it holding brackets, have to withstand the pressure inside the vessel. she must be dimensioned accordingly. It can also lead to inappropriateness that with such closures the opening of the vessel is also possible under pressure.

In contrast to this, the innovation suggests a lock for a such a color pressure vessel, in which a predominantly oval one Lid in the manner of a manhole cover rests with its sealing edge from the inside against the edge of the filling opening and in this Position even when there is no pressure from the outside by means of a clamping element is held.

The preferred catfish is the Spannelemont with two short parallel ones Arms and a longer lever arm connecting the short arms in a bow-like manner to form an angle lever, which is in bearing blocks is mounted on the lid and the closed position of the lid in the absence of overpressure ensures that its two

shorter arms after crossing their perpendicular to the edge of the opening Position below: Support the pretensioning of the seal on the edge zone around the opening.

In the drawing, an embodiment of the innovation is shown namely show

Figure 1 is a longitudinal section through the upper part

a color pressure vessel,

Figure 2 shows a section according to II-II of Figure 1, Figure 3 is a perspective view of the

Closing cover with the clamping element.

The pressure vessel 1 has an oval filling opening 2 at the top provided, which has a bent-up edge 3. The sealing edge 4 of the oval closure cover lies against this edge 3 from below 5 with its elastic seal 6. The cap 5 has two bearing blocks 7 / in which the Clamping element 8 is mounted in the form of an angle lever. This consists of the two parallel short arms 9 and a lever arm 10 which attaches at right angles to it and connects it in a bow-like manner, which is much longer. One of the two Bearing block 7 is a fork-shaped tab 11 with two aligned Bores 12 are provided for a locking pin or the like.

The application and mode of action of the closure are simple. After the vessel 1 has been filled, the lid 5 is inserted into the opening 2 inserted and rotated into the final position. With the help of the bracket-like Lever arm 10 or with a special handle, not shown in the drawing, it is pulled upwards, so that the sealing edge 4 with the seal 6 against the opening edge 3 from below. Then the tensioning element 8 is moved from the "open" position shown in dash-dotted lines to the solid position "Closed" position flipped over, with the shorter lever arms after exceeding the perpendicular position in a self-locking .. inclined position the cover 5 with compression of the seal 6 in hold on to the locking position.

Pressure can now be applied to the vessel . It can then no longer be opened. It remains closed even after the pressure has been released, whereby the angle lever 8 can still be fixed by a pin inserted through the bore 12 on the tab 11 of the one bearing block 7 to secure it against unintentional opening.

Claims (2)

I If * Schützainsgrüicihe 1. Closure for the filling opening of a color pressure vessel for paint spraying devices, characterized in that it consists of one with its sealing edge (4) in the manner of the known Manhole cover from the inside against the edge (3) of the opening adjacent, mainly oval cover (5.) consists of even with a pressure-free vessel by means of a clamping element (8) in the closed position is held. 2. Closure according to claim 1, characterized in that the clamping element (8) with parallel short arms (9) and a longer lever arm (10) connecting the short arms in a bow-like manner is formed into an angle lever which is in bearing brackets (7) on the cover and the closed position of the lid in the absence of overpressure thereby .sures _f that the two shorter arms (9.) are supported on the edge zone around the opening after exceeding their position perpendicular to the opening edge, with the seal (6) pretensioned. 28863
