DE2355779A1 - Cover for vehicle mounted large vessel - is kept closed by enclosing strap expanded to allow release from vessel mouth - Google Patents

Abstract

The cover swinging upwards on a horizontal axis is particularly for large cylindrical pressure or vacuum vessels on vehicles and containing liquids or viscous material. The cover is locked in the closed position by an enclosing strap expanding in order to release it. The strap can comprise two halves linked together and attached to the vessel or the cover. Expansion and contraction of the strap can be effected by a two-part rod actuated mechanically, pneumatically or hydraulically. The halves can be of U-section, fitting over the mating flanges on cover and vessel. The design combines sure sealing with ease of operation.

"Container closure, especially for large cylindrical containers on vehicles"

The invention relates to a container closure, especially for large cylindrical containers on vehicles, such as suction and pressure containers for liquids up to Viscous material with an end face that can be folded up around an upper horizontal axis, for example of the container closing container lid.

Such container closures are usually high Requirements placed on tightness and stability. to For this purpose, in known constructions, the container is opened by means of individual screws distributed over the circumference.

ben firmly screwed to the container. Such a closure However, because of the many screws that have to be loosened, it is cumbersome and laborious to open or close.

The invention is based on the object of creating a closure, which is characterized primarily by simple Ease of use distinguishes itself. In addition, the required tightness of the cover should be guaranteed. The invention accordingly consists essentially in the fact that to secure the in the closed position Container lid against opening a same enclosing, provided for opening the same expandable locking bracket is. Such a container lid allows a design which in a single operation by simple spreading can be opened.

In a preferred embodiment of the invention there is the locking bracket essentially consists of two directly or indirectly articulated with one another

or container lid
or on the container / hinged bracket halves. The free temple ends can here in a particularly advantageous manner by a - z. B. mechanically, hydraulically, pneumatically or the like. Actuatable and z. B. two-part - extendable and shortenable actuating linkage expandable or together-

be draggable.

It preferably grips the container or the container lid mounted expandable locking bracket over a flange or flange parts of the container and the container lid.

Further details of the invention are as follows Refer to the description of an exemplary embodiment. Show here

1 shows the end view of a container closure according to the invention and
FIG. 2 shows a section along line 2-2 of FIG. 2.

The container 10 (not shown in FIG. 1) can be folded up, for example about a horizontal axis χ the container lid 11 is articulated. The container 10, 10 has e.g. cylindrical shape, that of the container lid is bowl-shaped is adapted. At their facing ends, the container is provided with a flange 12, the container lid with a flange Γ3, each with a circular circumference, which are sealed from one another by a seal 14.

The container closure consists essentially of the two equally or unequal sized bracket halves I5 and 16, which by means of connecting pieces 17 of a joint 18 on the container, preferably as shown in the drawing are hinged.

The two free lower ends of the bracket halves I5 and 16 are diametrically opposite the joint 18 Actuating linkage I9 connected to each other that öaus two Partial units 20 and 21, which in turn each consist of a cylinder 22 and a sliding in the cylinder Piston with piston rod 23 is made. The two cylinders 22 are connected to one another by a joint 24, while the piston rods 23 are each connected by a joint 25 to one at the free Hinge bracket 26 attached to the end of the bracket halves are articulated.

As can be seen in particular from FIG. 2, the bracket halves 15 and 16 U-shaped cross-section, such that the cross-sectional legs, z. B. 15 a, the bow halves in the closed position, the plansche 12 and I3 encompass on both sides, so that a tight seal of the container is guaranteed. The paddles 12 and IjJ are marked with 27 and / or the U-legs 15 a of the bracket halves with roundings I5 b '

provided to prevent the bracket halves from reaching over the To facilitate splashing when closing the container with elastic compression of the seal 14.

In Fig. 1 and 2, the bracket halves 15 and 16 are in the extended Lines, in the open position with dash-dotted lines Lines shown as indicated at 15 ', 16'. Fig. 1 shows (right) the closed position and (left) the open position of the linkage unit 20, in which the piston rod is in its extended end position.

In the closed position, both linkage units 20 and assume their retracted position, in which both bracket halves 15 and 16 the flanges 12 and I3 of the container and of the Tightly enclose container lid I3.

To open the container, the cylinders 22 of both linkage units 20 and 21 are put under pressure so that the piston and piston rod 2j5 are extended out of the cylinders in opposite directions and thereby push the two bracket halves I5, 16 apart, the bracket halves 15 and 16 are in the direction of the arrow y ^^ or y ₂ are pivoted outwards about their common joint 18,

509820/0 136

the flanges 12 and I3 from the bracket halves I5 and in their position I5 'or 16' are released so that now the container lid 11 together with the plan IjJ from the container 10 or its flange 12, for example by pivoting it up about the axis x, in the direction of the arrow ζ (Fig. 2) can remove.

The invention is not limited to the illustrated embodiment, even if this is a particularly suitable one Represents embodiment of the invention. For example - for smaller containers, for example - instead of one locking bracket consisting of two halves, the halves of which are directly or indirectly articulated with one another

are bound, a z. B. be provided essentially two-part, / expandable locking bracket. Spreading can also of the locking clip mechanically, electrically or in any other way.

If necessary, the locking clip can also be attached to the container lid instead of the container, or it can be the locking clip with a simple or angular cross-section only serve to hold the container lid firmly against the container without pressing a flange on the container

to grip the lid and the container. But has that in the The embodiment shown in the drawing has the essential advantage that the sealing forces between the container lid and container as a result of the U-shaped encompassing of Plan vision or flange-like parts in the locking bracket or its halves can directly compensate without To claim the fastening parts such as hinges or the like. Between the container lid and the container.
