Abstract

The present invention relates to an anti-removal device for preventing theft of a liquid such as a fuel from a container such as a tank, wherein the anti-removal device is suitable for placing in a feed for the container, which feed is also suitable for filling the container with the liquid, and the anti-removal device comprises means for semipermanent and/or removable arrangement in the feed by means of two or more arms extending from the anti-removal device in the direction of at least one wall of the feed.

Description

Anti extraction device, insertion device, insertion assembly and method
The present invention relates to an anti-removal device for preventing theft of a liquid. The present invention also relates to an insertion member for the purpose of inserting such a device. The invention also comprises an assembly of an insertion member and an anti- removal device. The invention further relates to a method for inserting an anti-removal device.
Containers such as tanks are generally used to hold liquids such as fuels. Use is usually made of a feed line to carry the liquid into the container. An example hereof is a fuel tank with a feed line extending from an opening in the tank to the wall of the ship, such as the hull or the deck. The fuels used in ships, for instance for propulsion thereof, are generally relatively expensive and therefore attractive to third parties. It is a frequent occurrence for fuels to be siphoned off or pumped out of a fuel tank of a ship for use by such third parties. It is known to close a tank with a lock, such as a padlock, but this is usually undesirable because of the location of the opening, where use of a padlock is impractical.
In order to obviate such a drawback and to provide a solution to the problem of removal of fuel, the present invention provides an anti-removal device for preventing theft of a liquid such as a fuel from a container such as a tank, wherein the anti-removal device is suitable for placing in a feed for the container, which feed is also suitable for filling the container with the liquid, and the anti-removal device comprises means for semipermanent and/or removable arrangement in the feed by means of two or more arms extending from the anti-removal device in the direction of at least one wall of the feed.
An advantage of such an anti-removal device is that the removal of fuel from the tank can be prevented in simple manner. According to the present invention and within the scope of this document, a feed for a container is defined here not only as a filling channel or a filling opening of a container but also as other channels with which a container can be connected to the outside world. An air feed for venting of a container is for instance also defined within the scope of this invention as a feed.
A first preferred embodiment according to the present invention relates to an anti-removal device, also comprising
- a central frame,
- at least two arms extending from the central frame for the purpose of providing a connection between the central frame and at least one wall of the feed, wherein:
- the central frame and/or the arms, as seen in the throughflow direction of the feed, leave a part of the throughflow area clear in order to fill the container therethrough.
An advantage of this preferred embodiment is that the throughflow opening of the line is divided into a plurality of small openings, so that the fuel tank cannot be accessed by siphoning hoses or pump hoses. The arms for instance prevent the possibility of the anti- removal device being pushed out of the feed into the container. In opposite direction the arms prevent the possibility • of the anti-removal device being prised out of the fuel line. In the first case the arms are for instance pushed against a connecting nipple of a fuel tank, while in the other case a mounting member for a valve of the container situated at the open end of the feed prevents the possibility of the anti-removal device being prised out of the feed.
In a further preferred embodiment the arms are suitable for providing a clamping force for clamping the anti-removal device in the feed. Owing to such a clamping force the arms are held under bias against the wall of the feed, whereby placing will be very firm and the difficulty of removing the device, as described in the foregoing paragraph, is increased still further.
In a further embodiment the central frame of the anti-removal device preferably comprises an annular body for passage of at least a part of the liquid. An advantage hereof is that a relatively large opening can be provided for admitting the liquid into the container. This annular body also provides a strong element for attaching the arms thereto or for manufacturing the arms integrally therewith.
The arms preferably extend, as seen in the position of use, from the central frame in both the transverse direction and in the longitudinal direction or flow direction of the feed. A simplified construction hereby becomes possible while retaining the advantages stated in the foregoing.
The arms more preferably comprise a resilient material enabling bending inward at least in the transverse direction of the feed under a counter-pressure and/or clamping against the inner side of the wall of the feed. Such a device can hereby be placed in simple manner and further remain in place semi-permanently or in a manner difficult to remove, whereby the action for preventing removal of the fuel can be sustained for a long period of time.
The frame and the arms are here preferably manufactured comprising a material inert to fuel, such as a suitable plastic or metal. At least some of the arms also comprise an engaging element at the end. Such an engaging element has a form such that taking the device out of the feed is made even more difficult. Pointed outer ends of the engaging elements herein engage on said connecting nipple or mounting member of the valve.
In a further preferred embodiment the arms are arcuate and extend outward from a middle part parallel to the flow direction. The clamping force can hereby be achieved in an advantageous and robust manner.
A further aspect of the present invention relates to an insertion member for inserting a device as described in the foregoing into a feed for a container, comprising a substantially elongate insertion sleeve for holding the arms of the device therein in bent inward position. It hereby becomes possible in simple manner to place the anti-removal device into the feed for the container.
In a preferred embodiment at least a part of the insertion sleeve can be deformed for the purpose of following the feed of the container. This is advantageous when the feed of the container is provided with at least one bend, for instance close to an open end thereof.
A further aspect of the present invention relates to an assembly of an anti-removal device and an insertion member according to the present invention. The advantages of the present invention can be obtained in simple manner using such an assembly. A further aspect of the present invention relates to a method for inserting one or more of the devices of the foregoing claims, comprising steps for:
- providing an anti-removal device according to one or more of the foregoing claims,
- providing an insertion member according to one or more of the foregoing claims,
- placing the anti-removal device in the insertion member. An advantage of such a method is that the advantages of using the device according to the present invention can be obtained in simple manner.
Further steps are preferably provided here for:
- introducing the insertion member into the feed for the container,
- pushing the anti-removal device out of the insertion member by means of an elongate pusher member. Insertion of the anti-removal device is hereby made possible in simple manner.
Further advantages, features and details of the present invention are described in greater detail he- reinbelow on the basis of several preferred embodiments and with reference to the accompanying figures. In the figures :
- Fig. 1 shows a perspective view of a preferred embodiment according to the present invention;
- Fig. 2 shows an example of a first stage of placing of a device according to the present invention by means of an example of an insertion device;
Fig. 3 is a schematic representation of a second stage of this method;
- Fig. 4 is a schematic representation of a third stage of this method. Fig. 5 is a schematic representation of a fourth stage of this method.
A preferred embodiment according to the present invention (Fig. 1) relates to a fuel guard 1 for use in a fuel line for feed to a fuel tank. Such a fuel tank is preferably applied in transport means such as moving vehicles or ships, but can also be applied in fixed installations or in other manner.
Fuel guard 1 comprises a substantially annular frame arranged centrally in the device. This annular frame is provided on the inner side with a number of connecting arms 11, in this case four such connecting arms 11 arranged crosswise. It is of course possible to arrange a number other than four. The purpose of arms 11 inside frame 2 is to prevent the passage of a pump or siphoning hose. Subject to the dimensioning of frame 2 a suitable number of connections 11 must therefore be applied so as to prevent passage of such a hose.
Ten arms extend on the top side of frame 2. Ten arms 4 likewise extend on the underside of the frame. These arms have a dual purpose. On the one hand they serve to support or to fix the device in the fuel line. On the other hand they serve to prevent guiding of the siphoning hose or pump hose past the device for the purpose of unauthorized removal of fuel from the tank. In top view the arms provide a star-shaped obstruction to such a hose.
In order to strengthen the connection between the arms and the wall of the fuel line the arms 3 are provided with support elements 5 and arms 4 are each provided with a support element 6. These support elements take a form such that removal of the fuel guard from the fuel line is made very difficult, this improv- ing the protection provided by the device. For strengthening purposes the end elements 5 are widened by means of widened portion 9. The end of the element also has a cut-away portion 7 ending in a sharp edge 8. This sharp edge 8 ensures that it hooks into end elements 26, 27 of fuel line 23. Removal of the fuel guard from this line hereby becomes practically impossible.
The arms have a resilient property, whereby the arms are under bias after being moved inward. Fixing in the fuel line (Fig. 5) is hereby greatly simplified. Owing to the resilient action of the arms the end elements 5 and 6 are pressed simultaneously against the wall of line 23. Such a resilient action can be obtained by preforming of a resilient material during the manufacture of the product of figure 1. Suitable materials for this purpose comprise for instance metals and plastics, such as the plastics POM, PA, PP. An advantage of such plastics is that they are inert in an environment where a fuel, such as a hydrocarbon such as diesel and petrol, is present.
The method for placing the device in the fuel line is shown schematically in four stages in figures 2- 5. Fuel guard 1 is first inserted into an insertion sleeve 21 which has a smaller diameter than fuel line 23 in which fuel guard 1 has to be placed. During insertion into the insertion sleeve the arms of the device are moved toward each other such that they are placed under bias and fit inside the insertion sleeve.
The insertion sleeve is then introduced (Fig. 3) into the fuel line. A suitable position for placing of the fuel guard can here be chosen. The end of the insertion sleeve is herein placed at this position. In Fig. 4 the fuel guard is then pressed out of the insertion sleeve by means of a push-out rod 24. The arms of the fuel guard are hereby released and will engage on the wall of line 23. The fuel guard will hereby be attached firmly, though optionally to some extent slidably. As shown clearly in figure 5, the fuel guard is situated at a location in line 23.
A fuel line is normally attached between two outer ends. Use is made for this attachment of a nipple 27 or a mounting member 26 for a valve. In the example of a ship this mounting member 26 is generally situated somewhere in deck 25, although it may also be situated in the ship's side.
The resilient action of the arms of the fuel guard ensures that, when an attempt is made to remove the fuel guard, the end elements thereof will hook into nipple 27 or mounting member 26. The fuel guard is hereby present in effective manner inside the line. It is not possible to damage the fuel guard since, if this is attempted, it will simply slide downward in the line.
The present invention has been described in the foregoing with reference to several preferred embodiments. Different aspects of different embodiments are deemed as being described in combination with each other, wherein all combinations which can be made by a skilled person on the basis of this document must be included. These preferred embodiments are not limitative of the scope of protection of this text. The rights sought are defined in the appended claims.
